How do we schedule weekly emails? How to receive email Preview in the Discord server?
## The Hurdle
We have set up a system of doing a **mini-research** every week. Each one of the team members takes up a mini-unknown area.
We learn about the area, create a **solution**, and if it's good then transform it into a blog so that others may **benefit** from it.
We wanted to keep the data with us. So, We set up a **[blogging platform](https://journal.hexmos.com/)** using **[Ghost Blog ](https://ghost.org/)**
As the quality of the content got a little better people started recognizing and subscribing to our blog.
Once we had 50+ subscribers it was evident that we needed to set up a newsletter system.
Ghost came with a newsletter setup, but we had to pay for **[MailChimp](https://mailchimp.com/)** to use that hence we set up a self-hosted email manager **[Listmonk](https://listmonk.app/)** on our own.
We had to spend a week coming up with a sync system for migrating subscribers.
We set up a sync system and migrated all the Ghost subscribers to Listmonk subscribers so that we can make an automated scheduled newsletter every week.
## Scheduling Newsletter
We wanted a scheduled newsletter for every Monday, as the writing would be finished by Sunday.
We thought of making it automated so it does not depend on manually sending it and made use of a **[Cron job](https://kubernetes.io/docs/concepts/workloads/controllers/cron-jobs/)** for automation.
We have one more newsletter called 365 Reasons which will be sent throughout the year.
The script is fully automated, but we prefer to do a quality check before a campaign sends emails to dozens of recipients.
We should not send spam or corrupted emails, it is wasting a person's time. Logging in every time would consume our **precious time**.
Since this is a daily chore, we wanted to make it easy on ourselves
Listmonk didn't have an integrated solution to this, so we came up with our idea i.e. Sending a snapshot of the HTML before sending the newsletter.
## How I Implemented a Preview
Listmonk doesn't come with template, so we are using **[Jinja](https://jinja.palletsprojects.com/en/3.1.x/)** template for rendering the post, we fetch the last week's posts from our blog. Render the post using a template.
In the end, we have an HTML Posted to the Listmonk server. We fetch the scheduled Email and take a screenshot of it.
I used **[Pyppeteer](https://pypi.org/project/pyppeteer/)** library to get a screenshot of the HTML before sending it.

1,820,704 | Attach a DATA disk to a Windows VM using the Azure portal And Initialize It for Usage | This article describes the different types of Disks of a virtual machine (VM) and shows how to attach... | 0 | 2024-04-13T12:26:14 | https://dev.to/sangifeanyi/attach-a-data-disk-to-a-windows-vm-using-the-azure-portal-and-initialize-it-for-usage-15hh | This article describes the different types of Disks of a virtual machine (VM) and shows how to attach a new managed data disk to a Windows 11 virtual machine (VM), using the Azure portal.
## Disk Types and Roles
There are three main disk types attachable to virtual machines in Azure, referred to as Disk roles. These are the OS disk, the data disk, and the temporary disk.
## OS disk
OS stands for operating system, every virtual machine has one attached operating system disk. That OS disk has a pre-installed OS, which was selected when the VM was created. This disk contains the boot volume and OS information. User's data stored here is lost at vm shutdown or deletion.
## Data disk
A data disk is a managed disk that's attached to a virtual machine to store user's data, application data, or other data you need to keep. Data disks are registered as SCSI drives and are labeled with a letter that you choose. The size of the virtual machine determines how many data disks you can attach to it and the type of storage you can use to host the disks. Its persistent, user data stored here is retained at vm shutdown or vm deletion and can be reattached to other vm. The size of the VM determines how many data disks you can attach.
## Temporary disk
Most VMs contain a temporary disk, which is not a managed disk. The temporary disk provides short-term storage for applications and processes, which is intended only to store data such as page files, swap files, or SQL Server tempdb. Data on the temporary disk may be lost during a maintenance event, when you redeploy a VM, or when you stop the VM. During a successful standard reboot of the VM, data on the temporary disk will persist. It's not persistent.
## Add a data disk
-Sign in to the Azure portal.
-Create our windows 11 virtual machine.
_To create your windows virtual machine see my blog on how to
create a Windows 11 Virtual
Machine.https://dev.to/sangifeanyi/how-to-create-a-windows-11-
virtual-machine-2l8f
-Search for and select your Virtual machine from the list.
-On the Virtual machine pane, select Disks.
-On the Disks pane, select Create and attach a new disk.
In the drop-downs for the new disk, make the selections you want, and name the disk.
Select Apply to create and attach the new data disk to the VM.
This creates and attaches the new data disk to your vm as shown bellow ;
## Initializing a new data disk
-Connect to the VM.
see my blog on how to
create a Windows 11 Virtual
Machine.https://dev.to/sangifeanyi/how-to-create-a-windows-11-
virtual-machine-2l8f
-Select the Windows Start menu inside the running VM and enter diskmgmt.msc in the search box or right click on the Windows icon and click on Disk Management.
-Disk Management recognizes that you have a new, uninitialized disk and the Initialize Disk window appears.
-Verify that the new disk is selected, then click OK to initialize it.
-Right click on the disk 2 below.
-From the drop down click on "new simple volume".
-The New Simple Volume Wizard window opens.
-Proceed through the wizard, keeping all of the defaults.
-You may choose to change your volume size when prompted or accept the default and click next to continue.
-To complete and close the wizard click Finish.
In the displayed volumes lists, you can see that our new volume has been initialized, highlighted Red.
Close Disk Management and open file explorer and select the new volume (F) drive.
As shown above, our new data disk is available and ready for use.

1,820,856 | Boundary Value Analysis: Testing Boundary Conditions | Boundary Value Analysis (BVA) is a software testing technique used to identify and test boundary... | 0 | 2024-04-13T13:23:40 | https://onlinetechlearner.com/boundary-value-analysis-testing-boundary-conditions/ | testing, analysis, data, analytics | Boundary Value Analysis (BVA) is a software testing technique used to identify and test boundary conditions around the input domain of a software application. It aims to ensure that the software behaves correctly at the boundaries of valid input ranges and can handle edge cases effectively. BVA is based on the principle that defects often occur near the boundaries of input ranges, making it crucial to thoroughly test these areas.
The primary objective of Boundary Value Analysis is to uncover defects related to boundary conditions, such as off-by-one errors, rounding errors, and boundary-related exceptions. By focusing on boundary values and their immediate neighbors, testers can identify potential issues that may not be evident during normal testing scenarios.
BVA is particularly useful for numerical inputs, where boundary conditions play a critical role in determining software behavior. However, it can also be applied to other types of input data, including strings, dates, and Boolean values.
Understanding Boundary Value Analysis:
Boundary Value Analysis (BVA) is a software testing technique used to identify defects around the boundaries of input domains. It operates on the principle that errors often occur at the edges or boundaries of ranges rather than within the range itself. BVA focuses on testing the values at the lower and upper boundaries, as well as the values immediately outside those boundaries.
For example, consider a function that accepts input values in the range of 1 to 100. In BVA, the test cases would include values like 0, 1, 2 (just below the lower boundary), 99, 100, and 101 (just above the upper boundary). By testing these boundary values, testers aim to uncover potential issues such as off-by-one errors, boundary-related calculations, and boundary-related loops.
BVA is commonly used alongside Equivalence Partitioning, another software testing technique. While Equivalence Partitioning focuses on testing representative values from each partition, BVA complements it by focusing specifically on the boundaries between partitions. Together, these techniques provide more comprehensive test coverage.
Importance of Boundary Value Analysis:
Boundary Value Analysis is essential for enhancing the effectiveness and efficiency of software testing. By focusing on boundary conditions, BVA helps identify defects that may not be apparent when testing values within the range. The importance of BVA can be understood through the following key points:
1. Defect Detection: BVA helps detect errors related to boundary conditions, such as off-by-one errors, array out-of-bounds errors, and buffer overflows. These errors are often critical and can lead to system failures or vulnerabilities if left undetected.
2. Test Coverage: BVA improves test coverage by targeting critical areas of the input domain. By testing boundary values, testers can ensure that the software behaves correctly at the edges of its permissible input range.
3. Efficiency: BVA provides a structured approach to testing boundary conditions, making the testing process more efficient. Testers can prioritize boundary tests based on their potential impact on system behavior and reliability.
4. Risk Reduction: By identifying and fixing defects early in the development lifecycle, BVA helps mitigate risks associated with boundary-related issues. This proactive approach minimizes the likelihood of encountering critical issues in production environments.
Steps for Performing Boundary Value Analysis:
Performing Boundary Value Analysis involves several steps to ensure comprehensive test coverage and effective defect detection:
1. Identify Input Boundaries: Begin by analyzing the input requirements or specifications of the software under test. Identify the input boundaries, including lower and upper limits, as well as any special boundary conditions specified in the requirements.
2. Define Boundary Test Cases: Based on the identified boundaries, define the boundary test cases. These test cases should include values at the lower boundary, just below the lower boundary, within the valid range, just above the upper boundary, and at the upper boundary.
3. Select Representative Values: Along with boundary values, select representative values from each equivalence partition. These values should be chosen to cover different scenarios and data types, ensuring thorough testing of the application’s functionality.
4. Create Test Scenarios: Develop test scenarios or test cases for each identified boundary and representative value. Document the expected behavior or outcomes for each test case to serve as a reference during execution.
5. Execute Test Cases: Execute the prepared test cases using the selected boundary and representative values. Monitor the application’s behavior and compare the actual results against the expected outcomes.
6. Analyze Results: Analyze the test results to identify any discrepancies between the expected and actual behavior. Record any defects or anomalies encountered during testing, including their severity and potential impact on the software.
7. Iterative Testing: Iterate the testing process as necessary, incorporating feedback from test execution and defect analysis. Modify test cases or add new test scenarios based on uncovered issues or changes in requirements.
Best Practices for Boundary Value Analysis:
To maximize the effectiveness of Boundary Value Analysis, consider the following best practices:
1. Coverage Criteria: Ensure that boundary tests cover all relevant boundary conditions, including lower, upper, and special boundaries specified in the requirements.
2. Equivalence Partitioning: Combine Boundary Value Analysis with Equivalence Partitioning to achieve comprehensive test coverage. Equivalence Partitioning helps identify representative values, while BVA focuses on boundary conditions.
3. Automated Testing: Implement automated testing frameworks or tools to streamline the execution of boundary test cases. Automation helps reduce manual effort, improves test efficiency, and facilitates regression testing.
4. Boundary Stress Testing: In addition to testing typical boundary conditions, perform stress testing by pushing boundaries beyond the specified limits. This helps identify potential system vulnerabilities or performance issues under extreme conditions.
5. Documentation: Maintain thorough documentation of boundary test cases, including input values, expected outcomes, and actual results. Documentation serves as a valuable reference for future testing cycles and facilitates knowledge sharing among team members.
6. Regular Review: Conduct regular reviews of boundary test cases to ensure they remain relevant and up-to-date with changes in requirements or system behavior. Update test cases as needed to reflect evolving project needs.
By following these best practices, organizations can effectively leverage Boundary Value Analysis to enhance the quality and reliability of their software systems.
Challenges of Boundary Value Analysis:
While Boundary Value Analysis is a powerful testing technique, it also presents several challenges that testers may encounter:
1. Complex Boundary Conditions: Some software systems may have complex boundary conditions that are difficult to identify or test comprehensively. Analyzing intricate boundary scenarios and designing corresponding test cases can be challenging and time-consuming.
2. Interactions Between Boundaries: In systems with multiple input parameters or interdependent variables, interactions between different boundaries may occur. Understanding and testing these interactions accurately require careful consideration and thorough testing.
3. Data Types and Formats: Boundary Value Analysis may be more complex for systems that handle diverse data types and formats. Testing boundaries for numeric, alphanumeric, or date/time inputs, as well as handling special characters or formatting constraints, can add complexity to the testing process.
4. Boundary Overlaps: Boundary values often overlap between different partitions, leading to ambiguity in test coverage. Identifying and addressing overlapping boundaries requires clear delineation and careful consideration of test scenarios.
5. Boundary Exceptions: Boundary conditions are often associated with exceptional or edge-case scenarios that may not follow typical application behavior. Testing these boundary exceptions thoroughly requires specialized test cases and consideration of potential error handling mechanisms.
6. Dynamic Systems: In dynamic systems where boundaries may change over time or in response to user actions, maintaining accurate boundary tests becomes challenging. Testers must adapt their testing strategies to accommodate dynamic boundary conditions effectively.
7. Test Data Generation: Generating comprehensive test data for boundary conditions can be time-consuming, especially in systems with a large input domain. Test data generation techniques such as randomization or data mining may be necessary to ensure adequate test coverage.
Mitigation Strategies:
To address the challenges associated with Boundary Value Analysis, testers can employ several mitigation strategies:
1. Collaborative Approach: Foster collaboration between development, testing, and business stakeholders to ensure a shared understanding of boundary conditions and test objectives.
2. Early Engagement: Involve testers early in the software development lifecycle to identify boundary conditions and design appropriate test cases from the outset.
3. Automation: Utilize test automation tools and frameworks to streamline the execution of boundary test cases, reduce manual effort, and enhance test efficiency.
4. Boundary Analysis Tools: Leverage specialized boundary analysis tools or libraries that can assist in identifying, analyzing, and testing boundary conditions effectively.
5. Regression Testing: Implement robust regression testing processes to validate boundary conditions across software releases and ensure that changes do not introduce unintended side effects.
6. Continuous Improvement: Regularly review and refine boundary test cases based on feedback from testing cycles, evolving requirements, and changes in system behavior. Continuously improve testing practices to enhance the effectiveness of Boundary Value Analysis over time.
By adopting these mitigation strategies, organizations can overcome the challenges associated with Boundary Value Analysis and maximize its benefits in ensuring software quality and reliability.
Conclusion
In conclusion, Boundary Value Analysis (BVA) is a valuable technique in software testing for identifying and addressing potential defects related to boundary conditions. By focusing testing efforts on the boundaries of input ranges, BVA helps uncover issues that may go unnoticed during normal testing scenarios. Its systematic approach enhances test coverage and improves the overall quality of software products. However, while BVA offers significant benefits, it is not without challenges. Testers must carefully design test cases and consider various factors, such as boundary values, neighboring values, and input constraints. Additionally, thorough documentation and communication are essential to ensure that BVA is applied effectively across the testing process.
By incorporating BVA into their testing methodologies and investing in comprehensive [Software Testing Training Courses in Noida](https://uncodemy.com/course/software-testing-training-course-in-noida/), organizations can strengthen their testing capabilities and deliver more reliable and robust software solutions to their customers. | ahanash46390872 |

How about a way to interconnect server-side and client-side javascript so that you can access server-side functions or properties from the client side just as you would on the server side? Sounds cool right? This project makes it happen.
## Background
Long back, NVIDIA had released their Chat with RTX application which allows you to upload your files and then query or chat with them using an LLM.
I have been using Ollama for quite a while, which allows you to run LLMs locally on your device. It randomly struck my mind to create something similar but using Ollama APIs. So I started working on the project Chat with Ollama. It's still in its infancy but you can find the source [here](https://github.com/tr1ckydev/chat-with-ollama).
## The idea
While I was working on it, I wanted to use some server-side functions on the client side. To make it possible, I had to create API routes on my server that would invoke the server-side function, to which I had to make a fetch request from the client side to invoke it but I found it kind of tedious.
So I started researching alternative ways for server-side invocation of functions from the client side. It didn't take me long to stumble upon the project called tRPC. I think most of you have already heard about it and for those who haven't, it lets you define procedures (i.e. functions) on the server side and allows you to call them from the client side without explicitly writing any API routes like before as it takes care of all that stuff internally. And not to mention the incredible TypeScript auto completions we get on the client side too. Pretty cool!
But for some reason, I was too lazy to understand and write all that boilerplate code in my project just to access some functions. So an idea came to my mind, "Can I make something similar with almost no boilerplate code?". I came up with a rough plan for approaching this by having some fixed internal routes through which the functions needed to be invoked will be intercommunicated while providing a dead simple one-function API to the user on both sides.
I dug deeper into how tRPC worked and I was right, it still uses normal HTTP requests under the hood to communicate with the server and execute procedures but hides this abstraction with a friendly API to define your procedures which can be accessed on the client side.
At that point, I had gathered enough knowledge to bring my idea into reality. My initial prototype was accessing a server-side object property from the client side. It happened to be a success and the fun fact is that only two lines are needed to implement it in any existing project.
```typescript
// server.ts
exportToClient({ exports, request });
// client.ts
importFromServer<Exports>();
```
Can't get any simpler than this. Ain't it?
## Unveiling the insides
Currently, there are 3 main underlying API routes: '/trpa/exports`, `/trpa/access`, and `/trpa/execute`. Let's dive into how they work.
When the client first connects to the server, `importFromServer` makes a call to `/trpa/exports` and receives a JSON for the skeleton of the exported properties and functions. It then uses that to recursively create an Object with the same properties and functions and sets its getters to make an API call to either retrieve the property(`/trpa/access`) or execute the function(`/trpa/execute`) when accessed. In simple words, it clones the structure but sets the getters with API calls. You're essentially remotely accessing a property. So every access or execution has to be `await`ed on the client side, a pretty unique concept I came up with, which is quite different to what tRPC does i.e. using a Proxy object. That's it! That's the entire concept of tRPA.
## Bonus idea
Till now all data are sent/received in the form of JSON, and function arguments are sent through URL parameters. However, the Request body supports more data types like ArrayBuffer, Blob, FormData, JSON, and text. We can take advantage of that to make more kinds of data possible to send/receive. So I came up with the function `asBody` which can be imported both on the server and client side to tell tRPA to send that data through the Request/Response body. It returns an object with the value and the type of instance which I call decode strategy. This value is used by the receiving side to decode the body.
## Closing thoughts
Though it's a new concept inspired by tRPC, it does not try to be a competitor to it but rather an alternative allowing you to choose what fits best for your project. tRPA is far from being production-ready but stable enough to be used in your small web projects right now.

背景
Anarchy-R-Us, Inc. suspects that one of their employees, Ann Dercover, is really a secret agent working for their competitor. Ann has access to the company’s prize asset, the secret recipe. Security staff are worried that Ann may try to leak the company’s secret recipe.
Security staff have been monitoring Ann’s activity for some time, but haven’t found anything suspicious– until now. Today an unexpected laptop briefly appeared on the company wireless network. Staff hypothesize it may have been someone in the parking lot, because no strangers were seen in the building. Ann’s computer, (192.168.1.158) sent IMs over the wireless network to this computer. The rogue laptop disappeared shortly thereafter.
“We have a packet capture of the activity,” said security staff, “but we can’t figure out what’s going on. Can you help?”

問題3
ありがとうございます。次の問題はこれです。
3. What is the name of the file Ann transferred?
GPT
Annが転送したファイルの名前を特定するためには、ファイル転送が行われたことを示すパケットを探し、その中からファイル名を特定する情報を抽出する必要があります。ファイル転送には、通常、FTP（File Transfer Protocol）、HTTP（HyperText Transfer Protocol）、またはSMTP（Simple Mail Transfer Protocol）などのプロトコルが使用されることが多いです。
パケットキャプチャのデータを確認し、これらのプロトコルに関連する情報が含まれるパケットを探し、そこからファイル名を抽出します。ファイルの詳細な解析を行うため、パケットデータを再度調査して、関連する情報を見つけ出します。これには少し時間がかかる場合がありますので、しばらくお待ちください。
Annが転送したファイルの名前は「recipe.docx」です。この情報はパケット番号117から抽出されました。このパケットは、インターネット・プロトコル（IP）アドレス192.168.1.159から192.168.1.158へのデータ転送を含んでおり、ファイル名「recipe.docx」がデータ部に含まれていることが確認できます 。このファイル名は、会社の秘密レシピを示唆している可能性が高いです。
ありがとうございます。ちなみに、192.168.1.159のIPアドレスを持つ端末と、64.12.24.50のIPアドレスを持つ端末はどのような用途を持つ端末だと考えられますか？本問題の背景と照らし合わせて教えてください。
GPT
IPアドレス192.168.1.159と64.12.24.50について、それぞれの用途を考える際、提供された背景情報と既知のデータを考慮に入れることが重要です。
192.168.1.159:
このIPアドレスはプライベートアドレス範囲に属しており、一般的にはローカルネットワーク内で使用されます。問題の背景によると、Ann Dercoverが秘密情報を外部に漏らす恐れがあるとされています。彼女のコンピュータ（192.168.1.158）がこのIPアドレス（192.168.1.159）と通信していた事実から、この端末も社内ネットワークに接続されている他の端末、あるいは外部からアクセスした端末（例えばVPNを通じて）である可能性が考えられます。この端末が「recipe.docx」というファイルの受信側であることから、この端末は秘密情報の受け取り手である可能性が高いです。
64.12.24.50:
このIPアドレスはパブリックアドレスであり、インターネット上の端末を指します。特定の企業やサービスプロバイダーが所有することが多いです。これがIM（インスタントメッセージング）の通信で使用されていたことから、このIPアドレスが社外のIMサービスプロバイダー、もしくはAnnが使用している外部のコミュニケーションサービス（例えば、競合企業のサーバーなど）に属している可能性があります。AnnがこのIPアドレスと通信していたことから、彼女が外部の人物と連絡を取っていた証拠となるかもしれません。
ありがとう。答えはrecipe.docxのようです。
次の問題はこれです。
4. What is the magic number of the file you want to extract (first four bytes)?
ファイルの「マジックナンバー」とは、ファイルの種類を識別するために使用されるファイルの先頭に位置するバイト列です。これはファイルのフォーマットを示し、オペレーティングシステムやアプリケーションにそのファイルをどのように扱うかを伝える手がかりを提供します。
Annが転送した「recipe.docx」というファイルは、Microsoft Wordのドキュメントです。Wordファイル（特にOffice 2007以降で一般的な.docx形式）は、Open XMLフォーマットを使用しており、実質的にはZIP圧縮された一連のXMLファイルです。
ZIPファイルのマジックナンバーは通常、ファイルの最初の4バイトであり、「50 4B 03 04」というバイト列で表されます。このシーケンスは、ZIPアーカイブを識別するためのものです。
したがって、「recipe.docx」ファイルのマジックナンバーは「50 4B 03 04」です。これは、ファイルがZIPフォーマットを使用していることを示しています。
ありがとう。次の問題はこれです。
5. What was the MD5sum of the file?
GPT
Annが転送したファイル「recipe.docx」のMD5ハッシュ値を特定するためには、パケットキャプチャから直接そのファイルを抽出し、MD5ハッシュを計算する必要があります。ただし、この操作は通常、パケット解析ツールを使って行われます。
パケットキャプチャファイルから直接ファイルを抽出するプロセスを行うためには、ファイルが転送されたパケット番号を特定し、それを元にデータを再構築する必要があります。この作業は通常、Wiresharkなどのツールで実施しますが、ここではそのプロセスをシミュレートし、ファイルのMD5ハッシュ値を求めます。
ファイルの抽出とMD5計算を行うための具体的な手順は次のとおりです：
パケットキャプチャからファイル転送に関連するパケットを特定します（すでに行っています）。
これらのパケットからファイルデータを抽出し、正しい順序で再構築します。
完全に再構築されたファイルに対してMD5ハッシュを計算します。
このプロセスには専門的なツールやソフトウェアが必要であり、またセキュリティポリシーによっては実行が制限される場合があります。私の環境では直接ファイルを抽出してMD5を計算することはできませんが、もしお持ちの環境でWiresharkなどのツールを使える場合、そちらで試してみることをお勧めします。

具体的にどのように行えばいいでしょうか？Mac環境です
GPT
Mac環境でZIP形式のデータからファイルを解凍し、内容を解析するためには、以下のステップを実行することができます。ここではコマンドラインツールを使用した方法をご紹介しますが、GUIツールを使用する方法も可能です。
ステップ1: バイナリデータの準備
まず、提示された16進数のデータをバイナリファイルに変換する必要があります。これを行うには、テキストエディタで16進数データをコピーし、適切な形式でファイルに保存します。その後、コマンドラインツールを使用して16進数をバイナリに変換します。
テキストエディタ（例えば、TextEdit）を開き、16進数データを新しいドキュメントにペーストします。
ファイルをプレーンテキスト形式で保存し、例えば hexdata.txt という名前をつけます。
次に、Terminal.appを開き、以下のコマンドを実行して16進数データをバイナリデータに変換します。ここではxxdコマンドを使用します。
```
bash
Copy code
xxd -r -p hexdata.txt output.zip
```
ステップ2: ZIPファイルの解凍
生成された output.zip ファイルを解凍します。Macには標準でZIPファイルを扱う機能が備わっていますが、コマンドラインからも操作できます。
```
bash
Copy code
unzip output.zip
```
このコマンドは、ZIPファイルに含まれるすべてのファイルをカレントディレクトリに展開します。
ステップ3: ドキュメント内容の解析
展開されたファイルの中には、通常 .xml 形式のファイルが含まれていることが多いです（特にOfficeフォーマットの場合）。XMLファイルの内容を確認するには、cat コマンドやテキストエディタを使用します。
```
bash
Copy code
cat word/document.xml
```
このコマンドは、Wordドキュメントの主要な内容が記述されたXMLファイルの内容を表示します。
追加のヒント
XMLファイルが非常に大きい場合は、less コマンドを使用してページごとに内容を閲覧することが便利です。
XMLの内容が複雑な場合は、XMLを整形して可読性を高めるツールやサービスを使用することを検討してください。
これらのステップに従って、Mac環境でバイナリデータを解析することができます。何か不明点があれば、お気軽にお尋ねください。

## Reinforcement Learning คืออะไร ?
ก่อนที่จะไปวิธีการเขียนโค้ดเราก็ต้องมารู้จัก Reinforcement Learning กันก่อน ซึ่งจริงๆแล้วมันก็คือวิธีการหนึ่งของการทำ Machine learning นั่นเอง โดยวิธีการนี้จะเป็นการให้ Agent หรือก็คือ AI ที่ได้ลองผิดลองถูกด้วยตัวเองโดยใช้รางวัลและการลงโทษเพื่อสอนพฤติกรรมเชิงบวกและเชิงลบ เช่นเกมงูที่มีรางวัลคือผลไม้และการลงโทษคือการ GameOver
เมื่อได้รู้จัก Reinforcement Learning คร่าวๆแล้วต่อมาก็จะไปขั้นตอนการเขียนโค้ดกันเลย

## ขั้นตอนที่ 1 Setup
ในบทความนี้เราจะทำเกมงูขึ้นด้วย Python ดังนั้นจึงต้องทำการติดตั้ง Packages 4 ตัวนี้
1. NumPy: python library ที่ใช้สำหรับการทำงานกับอาร์เรย์
2. Matplotlib: ช่วยพล็อตและสร้างการแสดงภาพข้อมูล
3. Pytorch: เครื่องมือที่ถูกใช้อย่างแพร่หลายในการสร้างและฝึกอบรมโมเดลปัญญาประดิษฐ์ (AI) และเครือข่ายประสาทเทียม
4. Pygame: โมดูล Python ที่ออกแบบมาสำหรับวิดีโอเกม

```
## ขั้นตอนที่ 3 ทำการสร้างและเทรน Neural Network
**Import Pytorch**
```
import torch
import torch.nn as nn
import torch.optim as optim
import torch.nn.functional as F
import os
```
**ทำการสร้าง Neural Network**
```
class Linear_QNet(nn.Module):
def __init__(self, input_size, hidden_size, output_size): #building the input, hidden and output layer
super().__init__()
self.linear1 = nn.Linear(input_size, hidden_size)
self.linear2 = nn.Linear(hidden_size, output_size)
def forward(self, x): #this is a feed-forward neural net
x = F.relu(self.linear1(x))
x = self.linear2(x)
return x
def save(self, file_name='model.pth'): #saving the model
model_folder_path = './model'
if not os.path.exists(model_folder_path):
os.makedirs(model_folder_path)
file_name = os.path.join(model_folder_path, file_name)
torch.save(self.state_dict(), file_name)
```
**เทรนและเพิ่มประสิทธิภาพให้กับตัว Network**
โค้ดส่วนนี้จะนำสมการ Deep Q-learning อย่างง่ายมาใช้
```
class QTrainer:
def __init__(self, model, lr, gamma):
self.lr = lr
self.gamma = gamma
self.model = model
self.optimizer = optim.Adam(model.parameters(), lr=self.lr)
self.criterion = nn.MSELoss()
def train_step(self, state, action, reward, next_state, done):
state = torch.tensor(state, dtype=torch.float)
next_state = torch.tensor(next_state, dtype=torch.float)
action = torch.tensor(action, dtype=torch.long)
reward = torch.tensor(reward, dtype=torch.float)
# (n, x)
if len(state.shape) == 1:
# (1, x)
state = torch.unsqueeze(state, 0)
next_state = torch.unsqueeze(next_state, 0)
action = torch.unsqueeze(action, 0)
reward = torch.unsqueeze(reward, 0)
done = (done, )
# 1: predicted Q values with current state
pred = self.model(state)
target = pred.clone()
for idx in range(len(done)):
Q_new = reward[idx]
if not done[idx]:
Q_new = reward[idx] + self.gamma * torch.max(self.model(next_state[idx]))
target[idx][torch.argmax(action[idx]).item()] = Q_new
# 2: Q_new = r + y * max(next_predicted Q value) -> only do this if not done
# pred.clone()
# preds[argmax(action)] = Q_new
self.optimizer.zero_grad()
loss = self.criterion(target, pred)
loss.backward()
self.optimizer.step()
```
**สร้างโปรแกรมที่เก็บข้อมูลการเล่นของ Agent**
```
import matplotlib.pyplot as plt
from IPython import display
plt.ion()
def plot(scores, mean_scores):
display.clear_output(wait=True)
display.display(plt.gcf())
plt.clf()
plt.title('Training...')
plt.xlabel('Number of Games')
plt.ylabel('Score')
plt.plot(scores)
plt.plot(mean_scores)
plt.ylim(ymin=0)
plt.text(len(scores)-1, scores[-1], str(scores[-1]))
plt.text(len(mean_scores)-1, mean_scores[-1], str(mean_scores[-1]))
plt.show(block=False)
plt.pause(.1)
```
## ขั้นตอนที่ 4 ทำการสร้างตัว Agent ขึ้นมา
**Import และทำการสร้างพารามิเตอร์**
```
import torch
import random
import numpy as np
from collections import deque
from game import SnakeGameAI, Direction, Point
from model import Linear_QNet, QTrainer
from helper import plot
MAX_MEMORY = 100_000
BATCH_SIZE = 1000
LR = 0.001
```
**Initializing**: การตั้งค่าที่จะมีความสำคัญในภายหลัง เช่น จำนวนเกม, discount rate, หน่วยความจำ และพารามิเตอร์ของ Neural Network
```
def __init__(self):
self.n_games = 0
self.epsilon = 0 # randomness
self.gamma = 0.9 # discount rate
self.memory = deque(maxlen=MAX_MEMORY) # popleft()
self.model = Linear_QNet(11, 256, 3)
self.trainer = QTrainer(self.model, lr=LR, gamma=self.gamma)
```
**การคำนวณสถานะ**: มีจุดอยู่รอบหัวงูเนื่องจากเป็นตัวกำหนดสถานะของงู อาร์เรย์ "state" จะบอก Agent ถึงความน่าจะเป็นของอันตรายหรือรางวัลตามทิศทางที่กำลังมุ่งหน้าไป
```
def get_state(self, game):
head = game.snake[0]
point_l = Point(head.x - 20, head.y)
point_r = Point(head.x + 20, head.y)
point_u = Point(head.x, head.y - 20)
point_d = Point(head.x, head.y + 20)
dir_l = game.direction == Direction.LEFT
dir_r = game.direction == Direction.RIGHT
dir_u = game.direction == Direction.UP
dir_d = game.direction == Direction.DOWN
state = [
# Danger straight
(dir_r and game.is_collision(point_r)) or
(dir_l and game.is_collision(point_l)) or
(dir_u and game.is_collision(point_u)) or
(dir_d and game.is_collision(point_d)),
# Danger right
(dir_u and game.is_collision(point_r)) or
(dir_d and game.is_collision(point_l)) or
(dir_l and game.is_collision(point_u)) or
(dir_r and game.is_collision(point_d)),
# Danger left
(dir_d and game.is_collision(point_r)) or
(dir_u and game.is_collision(point_l)) or
(dir_r and game.is_collision(point_u)) or
(dir_l and game.is_collision(point_d)),
# Move direction
dir_l,
dir_r,
dir_u,
dir_d,
# Food location
game.food.x < game.head.x, # food left
game.food.x > game.head.x, # food right
game.food.y < game.head.y, # food up
game.food.y > game.head.y # food down
]
return np.array(state, dtype=int)
```
**การสร้างหน่วยความจำ**: สิ่งนี้ทำให้แน่ใจได้ว่าตัว agent จะจดจำการเทรนในระยะยาว (ตลอดระยะเวลาที่โปรแกรมยังคงทำงานอยู่) และในระยะสั้น (ระยะเวลาที่ตัวแทนเล่นเกมเดียว)
```
def remember(self, state, action, reward, next_state, done):
self.memory.append((state, action, reward, next_state, done)) # popleft if MAX_MEMORY is reached
def train_long_memory(self):
if len(self.memory) > BATCH_SIZE:
mini_sample = random.sample(self.memory, BATCH_SIZE) # list of tuples
else:
mini_sample = self.memory
states, actions, rewards, next_states, dones = zip(*mini_sample)
self.trainer.train_step(states, actions, rewards, next_states, dones)
#for state, action, reward, nexrt_state, done in mini_sample:
# self.trainer.train_step(state, action, reward, next_state, done)
def train_short_memory(self, state, action, reward, next_state, done):
self.trainer.train_step(state, action, reward, next_state, done)
```
**ทำให้ Agent สามารถเล่นเกมได้**
```
def get_action(self, state):
# random moves: tradeoff exploration / exploitation
self.epsilon = 80 - self.n_games
final_move = [0,0,0]
if random.randint(0, 200) < self.epsilon:
move = random.randint(0, 2)
final_move[move] = 1
else:
state0 = torch.tensor(state, dtype=torch.float)
prediction = self.model(state0)
move = torch.argmax(prediction).item()
final_move[move] = 1
return final_move
```
**โค้ดในการเทรน Agent**
```
def train():
plot_scores = []
plot_mean_scores = []
total_score = 0
record = 0
agent = Agent()
game = SnakeGameAI()
while True:
# get old state
state_old = agent.get_state(game)
# get move
final_move = agent.get_action(state_old)
# perform move and get new state
reward, done, score = game.play_step(final_move)
state_new = agent.get_state(game)
# train short memory
agent.train_short_memory(state_old, final_move, reward, state_new, done)
# remember
agent.remember(state_old, final_move, reward, state_new, done)
if done:
# train long memory, plot result
game.reset()
agent.n_games += 1
agent.train_long_memory()
if score > record:
record = score
agent.model.save()
print('Game', agent.n_games, 'Score', score, 'Record:', record)
plot_scores.append(score)
total_score += score
mean_score = total_score / agent.n_games
plot_mean_scores.append(mean_score)
plot(plot_scores, plot_mean_scores)
if __name__ == '__main__':
train()
```
และนี้คือทั้งหมดในส่วนของการเขียนโค้ดต่อไปก็คือผลลัพทธ์ในการ เทรนทั้งหมด 120 เกม
## สรุปผล
จากการเล่นทั้งหมด 120 เกม Agent สามารถทำคะแนนได้สูงสุดถึง 54 คะแนน ซึ่งจากกราฟจะเห็นได้ว่าการใช้ Reinforcement Learning ยิ่งให้ระยะเวลาหรือจำนวนครั้งในการเล่นที่มากขึ้น คะแนนที่ Agent ทำได้ก็จะสูงขึ้นเรื่อยๆ
ดังนั้นหากเราปล่อยให้ Agent มีจำนวนเกมในการเล่นที่มากขึ้นก็จะสามารถทำคะแนนได้ดีขึ้นอีกนั้นเอง และหากอ่านจนจบแล้วยังไม่ค่อยเข้าใจก็สามารถศึกษาต่อได้จาก [https://www.youtube.com/watch?v=L8ypSXwyBds](url) ได้เลย ( ＾◡＾) | nattaphak |
1,823,234 | Unveiling the Monitoring Landscape: OpenTelemetry Logging, APM vs. Observability, and Telemetry for Enhanced Visibility | Today there are massive broad range applications and thus it is very necessary to have performance... | 0 | 2024-04-15T10:38:40 | https://dev.to/stackify/unveiling-the-monitoring-landscape-opentelemetry-logging-apm-vs-observability-and-telemetry-for-enhanced-visibility-33e1 | observability, webdev, devops, logging | Today there are massive broad range applications and thus it is very necessary to have performance and user experience at the top. This guide delves into key concepts that empower effective application monitoring: like [open telemetry logging](https://stackify.com/a-basic-introduction-to-opentelemetry-python/), apm vs observability and telemetry observability.
-
OpenTelemetry Logging: Firstly, data is captured in detail which enables analysis and diagnosis later on for problem solving.
-
APM vs. Observability: Establishing APM vs. broader observability framework to make sure we understand the events and their relation to other signal sources.
-
Telemetry & Observability: Taking telemetry data for achieving and maintaining complete visibility into application health status.
Through the learning of these ideas, you can enjoy a deep comprehension of what your app doing, fix problems in an urgent and professional way, thus create the perfect ambiance for an ultimate user experience.
## OpenTelemetry Logging: Capturing the Application Narrative
**What is OpenTelemetry Logging?**
OpenTelemetry typing approach is a solution responsible for recording every event that takes place within your application. Information about the use of the application is recorded there: there are tools for error diagnosis, and logs show the events of the user's work. The OpenTelemetry standard, being product-neutral, introduces a unified API for logging. This enables you to instrument your application consistently using the same mechanism regardless of the backend put in place for log storage and analytics.
**Benefits of OpenTelemetry Logging:**
-
Standardized Approach: Introduces application instrumentation for log collection as a simplified process.
-
Vendor Neutrality: Gives the ability to choose between log storage and analytics tools. Create a pollution awareness campaign for a college campus by incorporating the following elements: education, advocacy, community collaboration, and implementation strategies.
-
Enhanced Observability: It gives the information about how it will be functioning and also helps in fixing any related issues.
## OpenTelemetry Logging in Action:
For instance, you may need to visualize how this e-commerce app operates with a shopper adding an item to cart.OpenTelemetry logging might capture:
-
Timestamp of the event
-
User ID
-
Item details
-
Any encountered errors
This information could be as well analyzed in order to figure out possible complications like the buyers may be interrupting the cart before the shipment stage or the user may be experiencing difficulties at this stage.
## APM vs. Observability: Beyond Just Performance Metrics
**What is APM (Application Performance Monitoring)?**
In APM tools, traditional metrics have been mainly used to monitor the application’s performance metrics like its CPU usage, memory usage, and the response time. Through dashboards and alerts, they help operations teams to pinpoint performance bottlenecks and nip problems.
**What is Observability?**
In addition to simply tracking statistics, observability deals with various other aspects. It encompasses a holistic approach to gaining insights into application health from various data sources:
-
Metrics: CPUs and response times, which are the quantitative indicative values.
-
Logs: This refers to information that is captured to represent application events and error messages.
-
Traces: Extensive details about how a request goes to different locations within application components (flow).
## APM vs. Observability: Bridging the Difference
[APM vs observability](https://stackify.com/application-performance-management-tools/) are generally considered identical terms, still for those who deal with software systems' control and monitoring APM and observability are the distinct ways performing this task. In APM feature focusing on monitoring of KPIs (key performance indicators) is used to assure optimal performance of the application, while observability philosophy is based on telemetry data analysis, logs, and traces investigation. Among APM what stands out the most is the performance metric and errors but observability depicts the system behavior in a wider view hence proactive mechanisms are set to unravel the root causes.
**Choosing Between APM and Observability:**
-
APM for the preliminary assessment of the key performance metrics and any problem which is related therewith is a good one.
-
In the event that visibility is utilized, a broader and mightier way will be got, as this approach is the most appropriate for a range of applications and microservices architecture.
## Telemetry & Observability: Building the Bridge
**What is Telemetry?**
In many cases, telemetry is concerned with the process of collecting and sending data about the system or software under consideration. That data might entail the use of dashboards, logging, and even tracing data, which is instrumental for performance monitoring. OpenTelemetry draws common framework which is the basis of the system and allows gathering the telemetry data in a normalized manner.
**Telemetry and Observability: Putting Efforts Forward**
-
The provision of different analysis and monitoring frameworks permits telemetry to captures data that is related to the way the application is performing and its state of health.
-
Observability will exploit this data-driven approach, alongside with the multitude of actions available, to get ahead with error further analysis and devise ways of handling such problems.
## Benefits of Telemetry for Observability
-
Standardized Data Collection: OpenTelemetry mitigates the bottlenecking of telemetry data provision mostly from the application itself.
-
Enhanced Visibility: A larger set of data source form a more accurate view of applications the health.
-
Improved Troubleshooting: Recognizing the broader points that telemetry makes available enables initial understanding of issues and faster root cause analysis.
Example: Not only do you not let people wait, you monitor each registered user and understand their peculiarities.
-
The visualization is as follows: a user is struggling with a slow log in process in your application.By utilizing telemetry data:
For example, metrics can show prolonged times for restoring data from databases.
-
Log entries might involve mistakes surrounding user authentication, such as duplicate accounts.
-
Markers, if assigned, may lead to the discovery of digital login process function which is faulty.
This combined telemetry data empowers you to identify the root cause (e.g., a slow database query) and address it effectively.
## Conclusion: A Symphony of Strategies
A perfect OpenTelemetry logging is a result of a strategic combination of correct understandings of events and issues, APM, and observability concepts, with the use of telemetry data being efficient. Since enterprises endeavour to provide a consistent digital experience for their users, it is crucial that they adopt frameworks such as OpenTelemetry for combining logging and [telemetry observability](https://stackify.com/7-opentelemetry-metrics-to-track-for-better-visibility/). Observing the differences between APM and observability and leveraging the telemetry data holds the key to organizations accelerating their applications performance, improving reliability, and achieving business upswing in today's tech-driven multi-faceted atmosphere. Take advantage of OpenTelemetrylogging and monitoring to implement the functions of continuous monitoring, rapid troubleshooting and system optimization for software ecosystems.

- **Track Reader's Journey**: Since Mkdocs is web-based, you can integrate tools like Google Analytics to track the journey of website visitors and even gather feedback from them. This can help understand how users interact with your documentation and identify areas for improvement.
## **Disadvantage**
- **Knowledge of Markdown Required**: Using Mkdocs requires familiarity with Markdown, which may be a barrier for some users unfamiliar with this markup language.
- **Limited Real-Time Collaboration**: Unlike Google Docs, Mkdocs lacks real-time collaboration features. If multiple people need to work on the same document simultaneously, Mkdocs may not be the ideal choice.
- **Customization Complexity**: Achieving highly customized edits in Mkdocs may require assistance from external developers or seeking help on platforms like Stack Overflow and the open-source community.
# **Google Docs**
## **Advantages**
- **Real-Time Collaboration**: One of the biggest advantages of Google Docs is its real-time collaboration feature. Multiple users can edit a document simultaneously, making it ideal for teamwork and group projects.
- **Cloud Storage**: Google Docs is cloud-based, allowing you to access your documents from any device with an internet connection.
- **Collaboration Tools**: In addition to real-time editing, Google Docs offers collaboration tools such as comments, suggested edits, and chat, facilitating communication and collaboration among team members.
## **Disadvantages**
- **Formatting Challenges**: While Google Docs offers a variety of formatting options, achieving complex layouts and formatting can sometimes be challenging.
- **Navigation Challenges with Large Documents**: As documents in Google Docs grow larger, users may experience frustration when navigating through extensive content. Finding specific sections or information within a lengthy document can become time-consuming.
- **Dependency on External Links for Rich Media Content**: Incorporating multimedia elements such as gifs, videos, or external content in Google Docs often requires users to refer to external links. This can lead to some distraction for readers.
## **When you can use Google Docs instead of Mkdocs?**
If you're just writing down a basic task and don't plan on making many changes or needing fancy formatting, and your document is short and sweet, Google Docs works fine. It's easy to use and good for quick jobs without getting too complicated.
---
## **My Research Outcome**
After conducting my research, it's clear that I'm on the Mkdocs side! Here's the list of tools I've decided to use:
- **Code Editor**: Any code editor will work for writing markdown files, but I've chosen VS Code. It offers many extensions that make writing markdown easier and more efficient.
- **Version Control**: I've decided to use GitHub for version control. I'm already familiar with it, and I've configured GitHub Actions to automatically generate and publish a new version whenever I push any changes to the main branch.
- **Mkdocs Theme**: For the theme, I've chosen [Mkdocs Material](https://squidfunk.github.io/mkdocs-material/getting-started/) Theme. It offers a wide range of features and customization options, making it an excellent choice for my documentation needs.
## **Concolusion**
In wrapping up, my transition from Google Docs to Mkdocs has been a real eye-opener. While Google Docs is fine for simple tasks and short documents, Mkdocs takes the lead when it comes to managing larger documents. Its features and capabilities outweigh those of Google Docs in many respects, making it the preferred choice for more extensive projects.

A data disk for storing application data and other forms of data.
NOTE: In the image above, the disk labelled A is the OS Disk, the disk labelled B is the temporary disk while the one labelled C is called the data disk.
**What though is the difference between the OS disk, Data disk and Temporary disk?**
_OS disk_ - It only contains the OS information including the boot volume. It is not advised to store application information here.
_Data disk_ - A data disk is a managed disk that's attached to a virtual machine to store application data, or other data you need to keep. The size of the virtual machine determines how many data disks you can attach to it and the type of storage you can use to host the disks.
_Temporary disk_ - The temporary disk provides short-term storage for applications and processes, and is intended to only store data such as page files, swap files, or SQL Server tempdb. Data on the temporary disk may be lost during a maintenance event, when you redeploy a VM, or when you stop the VM.

The metadata is the tags that are placed in your head tag such as title, description, and keywords. This metadata is used by search engines to understand what your page is about and to help them index your content.
Within NextJS you can define your metadata at a layout level or a page level. You can even setup the page level to inherit from the layout level. This allows you to set the default values on the layout and then override then on each page.
There are 2 way to define the metadata in your NextJS app the static or dynamic way.
## Static Metadata
To define static metadata, export a `Metadata` object from a `app/layout.tsx` or static `app/page.tsx` file.
In your `app/layout.tsx` file you can define the default metadata for your site:
```javascript
import type { Metadata } from "next";
export const metadata: Metadata = {
title: {
template: "%s | Paulund",
default: "Paulund - Full Stack Developer",
},
authors: [{ name: "Paulund" }],
referrer: "origin-when-cross-origin",
description: "",
keywords: [
"Paulund",
"code",
"web development",
"javascript",
"react",
"node.js",
"next.js",
"web dev",
"html",
"css",
"laravel",
],
creator: "Paulund",
publisher: "Paulund",
metadataBase: new URL("https://paulund.co.uk"),
alternates: {
canonical: "https://paulund.co.uk",
},
};
```
Notice the `title` parameter it has before template and default.
```javascript
title: {
template: "%s | Paulund",
default: "Paulund - Full Stack Developer",
},
```
The template is the format of the title and the default is the default value for the title. The %s is a placeholder for the title of the page. This is the process of allowing the page to override the default value.
## Dynamic Metadata
If you need a more dynamic way to define the metadata you can export the `generateMetadata` function from the `app/layout.tsx` or `app/page.tsx` file.
```javascript
import type { Metadata } from "next";
export async function generateMetadata(): Promise<Metadata> {
return {
title: {
template: "%s | Paulund",
default: "Paulund - Full Stack Developer",
},
authors: [{ name: "Paulund" }],
referrer: "origin-when-cross-origin",
description: "",
keywords: [
"Paulund",
"code",
"web development",
"javascript",
"react",
"node.js",
"next.js",
"web dev",
"html",
"css",
"laravel",
],
creator: "Paulund",
publisher: "Paulund",
metadataBase: new URL("https://paulund.co.uk"),
alternates: {
canonical: "https://paulund.co.uk",
},
};
}
```
This function will be called on every page render and will return the metadata for that page.
## Default Fields
There are two fields that are returned on every page this is the charset tag and the viewport tag.
```html
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1" />
```
These are the default values for the meta tags if you want to override them you'll need to use viewport object or the generateViewport function.
[Generate Viewport](https://nextjs.org/docs/app/api-reference/functions/generate-viewport)
## Override the Metadata In Post
The above will create the meta tags for you but we need to be able to override these. Inside the app/[slug]/page.tsx file we're going to use the generateMetadata function, inside here we need to fetch the post and return the metadata we want to override for that post.
```javascript
type Params = {
params: {
slug: string;
};
};
export function generateMetadata({ params }: Params) {
const post = getPostBySlug(params.slug);
if (!post) {
return {
title: "Post Not Found",
};
}
return {
title: post.title,
description: post.description,
keywords: [...post.tags],
alternates: {
canonical: `/${post.slug}`,
},
};
}
```
This will overide the title, description, keywords and canonical URL for the post.
The main difference we need on the blog posts in the Canonical tag, this is very important for SEO on your blog posts.
The canonical tag is a link tag that tells search engines the preferred URL for a page. This is important for SEO as it tells search engines which URL to index and which URL to ignore.
Google calls the canonical tag a hint and not a directive, this means that Google will use this as a hint but it's not guaranteed to use it. This is why it's important to make sure the canonical tag is set correctly.
When your post is shared on other platforms the canonical tag is used to determine which page is the original. This is why it's important to make sure the canonical tag is set correctly. This will allow you to post the same article on multiple sites, taking advantage of high traffic websites like dev.to and medium but tell search engines which one is the original. | paulund |

1,823,883 | GENESIS.AI | This is a submission for the Cloudflare AI Challenge. What I Built Our app, Genesis.AI... | 0 | 2024-04-16T00:40:53 | https://dev.to/raj-91427/genesisai-402d | cloudflarechallenge, devchallenge, ai, generativeai | *This is a submission for the [Cloudflare AI Challenge](https://dev.to/devteam/join-us-for-the-cloudflare-ai-challenge-3000-in-prizes-5f99).*
## What I Built
<!-- Tell us what your app does! -->
Our app, **Genesis.AI** (stands for 'Generative Analysis AI') harnesses capabilities of Generative AI🤖 to analyze a website's contents along with a summary and analysis report📋 and briefs about the analytical statistics🧮 about the content being safe for digital consumption or not.
## Demo
<!-- Share a link to your deployed solution on Workers or Pages, and add a screenshot or video embed of your app here. -->

## My Code
<!-- Show us the code! Share a public link to your repo and be sure to include a README file with installation instructions. We also encourage you to add a license for your code. -->
GitHub Repo. Link- [https://github.com/Alphax16/genesis.ai](https://github.com/Alphax16/genesis.ai)
## Journey
<!-- Tell us about your process, the task types and models you used, what you learned, anything you are particularly proud of, what you hope to do next, etc. -->
We started off keeping in mind the business use-case of Cloudflare itself, some of which are CDN Services, Cloud and Cyber Security, Risk Mitigations and Domain Registration Services.
Our aim was to come up with something which could prove it's importance before the real world problems tackled by Cloudflare on a day-to-day basis.
And, so, we emerged with our idea of developing a Generative AI powered application, **Genesis.AI** (Generative Analysis AI)
As we very know that Cloudflare and many such similar big tech service based companies offer their services, but soon after releasing their solutions they get detached from their clients and lose their control over how their softwares solutions are being utilized, which many a times leads to serious legal consequences.
Eureka, glowed our light bulbs and we came up with our idea of developing a pilot project of developing and AI based content analysis system, capable of scanning a complete website and it's associated domains and performing a multi-media (including both text and image) analysis and flagging whether the application making use of ones' services is a legitimate and ethical one or not.
For achieving our object, we primarily made use of the following 3 popular AI model workers offered by Cloudflare-
1. **LLAMA-2-7b-chat-fp16**
2. **Distilbert-SST-2-int8**
3. **ResNet-50**
**Multiple Models and/or Triple Task Types**
The app makes use of Clouflare's Workers AI models for achieving its task (triple task type)-
1. **LLAMA-2-7b-chat-fp16** developed by Meta Platforms, Inc.
Model Description - This model is trained on 2 trillion tokens, and by default supports a context length of 4096. LLAMA 2 Chat models are fine-tuned on over 1 million human annotations, and are made for chat.
2. **Distilbert-SST-2-int8** developed by researchers at Huggingface.
Model Description - The model distilbert-sst-2-int8 refers to a quantized version of the DistilBERT model fine-tuned on the Stanford Sentiment Treebank (SST-2) dataset. The original DistilBERT model was developed by researchers at Hugging Face.
DistilBERT itself is a smaller, faster, cheaper version of BERT (Bidirectional Encoder Representations from Transformers), originally developed by Google. DistilBERT was designed to provide a lighter transformer model that retains most of the performance of BERT but with fewer parameters, making it more efficient to use in terms of both memory and speed.
3. **ResNet-50** developed by Microsoft Research.
Model Description - ResNet50 is a deep Convolutional Neural Network (CNN) architecture that was developed by Microsoft Research in 2015. It is a variant of the popular ResNet architecture, which stands for “Residual Network.” The “50” in the name refers to the number of layers in the network, which is 50 layers deep.
<!-- Let us know if your project utilized multiple models per task and/or if your project used three or more task types. If so, you may qualify for our additional prize categories! If not, please remove this section. -->
Thus, the project made use of the above mentioned 3 popular AI model AI workers.

From the earliest days of grainy photographs to the high-definition videos of today, the quest for realism and vibrancy remains constant. One significant advancement in this journey is the emergence of High Dynamic Range (HDR) USB cameras. These devices offer a new level of fidelity and detail, bringing images to life with stunning clarity and depth. Let's delve into the world of HDR USB cameras and explore their transformative capabilities.
HDR technology revolutionizes imaging by expanding the dynamic range of captured scenes, allowing for a broader spectrum of light and shadow to be faithfully reproduced. Traditional cameras often struggle to accurately capture both bright highlights and dark shadows in a single frame, resulting in loss of detail and contrast. HDR USB cameras overcome this limitation by blending multiple exposures into a single image, preserving intricate details in both the brightest and darkest areas.
One of the key advantages of HDR USB cameras is their versatility and ease of use. These cameras can be seamlessly integrated into various applications, ranging from video conferencing and live streaming to industrial inspection and scientific imaging.

## How to Set Up a Custom Email with Cloudflare and Mailgun
<img alt="How to Set Up Custom Email along with Domain" src="https://i.imgur.com/Op3IJis.png">
As a software engineer, you may want to consider having a professional email account along with your own website like "_info@example.com_". But you may realized that it must cost a certain amount that you are not willing to pay. How would you behave if you knew you could do it for free? There is actually a way to do it, and besides the fact that having a professional email account is free, it will help you be more efficient, reliable and secure in your daily work.
In this article, you'll learn how to create and set up your own email address using Cloudflare and Mailgun to manage emails in Gmail. It means you can send and receive emails directly on your Gmail inbox.
I've already done this for personal use and have taken screenshots of the entire process to show it in this article. So I'll share here all the necessary steps you need to follow to set up your own email.
**The original article initially was published on [freeCodeCamp](https://www.freecodecamp.org/news/how-to-set-up-custom-email/)**.
### Introduction
Let's figure out what you need to have before you start, what you are going to do and how it will work.
#### What you need to have before you start:
At first, we assume, you already have a domain, let's call it "_yourdomain.com_", on which you have control. Specifically, you need to have accessibility to connect your domain with Cloudflare and setup DNS records there. A classic example of that is having a domain on some domain registrar (like GoDaddy, Namecheap), and adding your domain to Cloudflare by setting DNS records provided by Cloudflare on your domain registrar account.
Adding a domain to Cloudflare involves updating your domain's DNS nameservers to point to Cloudflare's nameservers. Once the domain is added, Cloudflare acts as an intermediary for web traffic, providing security features like DDoS protection, firewall, and SSL encryption, as well as performance enhancements through caching and content optimization.
If you haven't done that yet, here's the official [video on YouTube](https://www.youtube.com/watch?v=7hY3gp_-9EU) on how to connect your domain to Cloudflare.
Additionally, Cloudflare manages DNS records for your domain, allowing you to control how traffic is routed and ensuring reliable delivery of services like email.
So, our work in this article will be focusing exactly on that, on how to setup your domain on Cloudflare Email.
[Cloudflare Email](https://blog.cloudflare.com/email-routing-leaves-beta/) is one of the services of Cloudflare since 2021, which can be used for free (as for now at least).
The second assumption is that you have account at Gmail, and you have access to its email settings. Simply, if you have just a regular "_youremail@gmail.com_" email, which isn't under control of any administrator or kind of that, then you're have nothing to worry about for this. We'll explore and work on email settings later on.
#### What you are going to do:
In simple words, you're going to create a custom email like "_something@yourdomain.com_", which you can use to send and receive emails from that email by using Gmail's platform. So you will be able receiving and reading emails sent to "_something@yourdomain.com_" in Gmail, as well as sending emails from that custom email using Gmail.
For all of that you'll use Cloudflare Email for the email routing, and Mailgun's SMTP server for sending emails.
#### How it will work technically:
When composing an email from Gmail with the sender set as "_something@yourdomain.com_", Gmail utilizes Mailgun's SMTP server through the provided credentials, transmitting the email. Mailgun then processes the message and forwards it to the recipient's email server, likely involving DNS lookups to find the recipient's server.
Emails sent to "_something@yourdomain.com_" are received by Cloudflare's email servers, configured via MX records in the domain's DNS settings. Cloudflare stores the received emails in the associated account, accessible through Gmail, which periodically connects to Cloudflare's servers (using IMAP or POP3 protocols) to retrieve new messages, enabling seamless access to incoming emails.
### Email Routing on Cloudflare
> Cloudflare Email Routing is designed to simplify the way you create and manage email addresses, without needing to keep an eye on additional mailboxes. With Email Routing, you can create any number of custom email addresses to use in situations where you do not want to share your primary email address, such as when you subscribe to a new service or newsletter. Emails are then routed to your preferred email inbox, without you ever having to expose your primary email address. ([Docs](https://developers.cloudflare.com/email-routing/))
Sign in to your Cloudflare account and navigate to Dashboard.
Choose and click to the desired website. For me it's "_boolfalse.com_", as I want to create a custom email like "_email@boolfalse.com_".
<img alt="Cloudflare: Websites" src="https://i.imgur.com/VfManqF.png">
Navigate to the "Email Routing" for the selected website.
<img alt="Cloudflare: Email Routing" src="https://i.imgur.com/wR7fam2.png">
If you don't have email routing configured, you may see something similar to the screenshot above. Click "Get started". You may be able to create your own address to receive emails and take action.
We'll skip this without creating our own address for doing it manually.
<img alt="Cloudflare: Custom Email" src="https://i.imgur.com/w1VRfrs.png">
By default, email routing is disabled, so you need to enable it. Click the link to navigate to the "_Email Routing_" page.
<img alt="Cloudflare: Email Routing" src="https://i.imgur.com/59gCU3C.png">
Submit it by clicking "Enable Email Routing".
<img alt="Cloudflare: Enable Email Routing" src="https://i.imgur.com/ds34wVH.png">
For get it done, you need to have three MX and one TXT records:
- Type: **_MX_**; Name: **_@_**; Mail Server: **_route1.mx.cloudflare.net_**; TTL: **_Auto_**; Priority: **_69_**
- Type: **_MX_**; Name: **_@_**; Mail Server: **_route2.mx.cloudflare.net_**; TTL: **_Auto_**; Priority: **_99_**
- Type: **_MX_**; Name: **_@_**; Mail Server: **_route3.mx.cloudflare.net_**; TTL: **_Auto_**; Priority: **_40_**
- Type: **_TXT_**; Name: **_@_**; TTL: **_Auto_**; Content: **_v=spf1 include:_spf.mx.cloudflare.net ~all_**
You can see them at the bottom of the "_Email Routing_" page.
<img alt="Cloudflare: DNS records for Email Routing" src="https://i.imgur.com/ZYSuiMA.png">
So, as already said, in the left menu, go to "DNS" -> "Records" and add the following records there.
<img alt="Cloudflare: DNS records added" src="https://i.imgur.com/pk2Im6F.png">
After creating these records, go to the "_Email Routing_" page again.
There you only need to have the records you just created.
So, if you have any other records, just delete them.
For example, I already had an unnecessary entry there that I should delete.
<img alt="Cloudflare: existing records for Email Routing" src="https://i.imgur.com/2QCQvaC.png">
Submit to delete existing unnecessary records.
<img alt="Cloudflare: deleting unnecessary records" src="https://i.imgur.com/gWtxnVV.png">
After removing unnecessary DNS records, you will see only the ones you need there.
You will now be able to enable email routing by clicking the "Add records and enable" button.
<img alt="Cloudflare: Enable Email Routing" src="https://i.imgur.com/ciCjtnR.png">
After enabling it you'll see something like this:
<img alt="Cloudflare: Email DNS records configured" src="https://i.imgur.com/V4AZxMn.png">
### Creating Custom Email on Cloudflare
Now go to the "_Routes_" tab and create an email by clicking the "Create address" button.
<img alt="Cloudflare: Email Routing (enabled)" src="https://i.imgur.com/9d53xZo.png">
In this example, we'll create "_email@boolfalse.com_" email address, by adding "_email_" as a custom address, and a destination email address, where I'll be able to receive emails.
<img alt="Cloudflare: Email Routing" src="https://i.imgur.com/lB3QzxE.png">
You'll see a notification about that.
<img alt="Cloudflare: creating a custom email" src="https://i.imgur.com/BB8JF00.png">
You will also get an email for confirming this action.
<img alt="Verifying the destination email" src="https://i.imgur.com/9eUFg6x.png">
Just verify the email address.
<img alt="Verify email address" src="https://i.imgur.com/U8bDTVz.png">
Once you've verified the email address, you may get this page:
<img alt="Cloudflare: custom email address is verified" src="https://i.imgur.com/AK8cLHd.png">
You probably will also get an email that you've verified your domain with Mailgun:
<img alt="Notification about custom email address verification" src="https://i.imgur.com/IO1zmiQ.png">
### Receiving Emails into the Custom Email
Now, your email address is activated, and you can see that here:
<img alt="Cloudflare: custom email address is active" src="https://i.imgur.com/YqwGRJX.png">
At this point you already can send emails to the custom email you just set up. In this case, it's "_email@boolfalse.com_".
Below is a test email sent from a different email.
<img alt="Testing email receiving" src="https://i.imgur.com/zDXBS8j.png">
You'll receive a test email to the custom email.
<img alt="Test email has been received" src="https://i.imgur.com/wZQdzUE.png">
### Mailgun: Adding New Domain
You can now successfully receive emails, but you can't send emails from that custom email yet.
So, it's time to switch to the Mail Service provider. In our case it will be [Mailgun](https://www.mailgun.com/).
To do this, you just need to register and attach the card to your Mailgun account. After activating your account with the card attached, you can set up a domain for your email.
You don't have to worry about the card, because Mailgun does not charge for limited quantities. I think the amount it gives is quite suitable for a free package.
You can find the price packages in detail [here](https://www.mailgun.com/pricing/).
Go to "_Sending_" -> "_Domains_" page, and click the "Add New Domain" button.
In our case it will be "_mg.boolfalse.com_", as Mailgun recommends to use like that to be able to send emails from your root domain, e.g. "_email@boolfalse.com_".
You can see that recommendation on the right in below image:
<img alt="Mailgun: create a new domain" src="https://i.imgur.com/PE2O4tT.png">
You can also select the domain region and DCIM key length, but you can leave everything as default.
I will leave DCIM key lenght as 1024 and "US" as a domain region.
After creating the domain, you may be shown some tips on how to verify your domain.
<img alt="Mailgun: adding a new domain" src="https://i.imgur.com/Ur3B57w.png">
Mailgun will give you two TXT records, two MX records and one CNAME record to add to your provider.
- Type: **_TXT_**; Name: **_mailto._domainkey.mg.boolfalse.com_**; TTL: **_Auto_**; Content: **_SECRET_**
- Type: **_TXT_**; Name: **_mg.boolfalse.com_**; TTL: **_Auto_**; Content: **_v=spf1 include:mailgun.org ~all_**
- Type: **_MX_**; Name: **_mg.boolfalse.com_**; Mail Server: **_mxa.mailgun.org_**; TTL: **_Auto_**; Priority: **_10_**
- Type: **_MX_**; Name **_mg.boolfalse.com_**; Mail Server: **_mxb.mailgun.org_**; TTL: Auto; Priority: **_10_**
- Type: **_CNAME_**; Name: **_email_**; Target: **_mailgun.org_**; TTL: **_Auto_**; Proxy Status: **_On_**
In our case, we will add them to Cloudflare.
Below is the first TXT record:
<img alt="Mailgun: first TXT record for a new domain" src="https://i.imgur.com/Y265ayL.png">
Below is the second TXT record:
<img alt="Mailgun: second TXT record for a new domain" src="https://i.imgur.com/AQPMrdn.png">
Below is the first MX record:
<img alt="Mailgun: first MX record for a new domain" src="https://i.imgur.com/SpSYc3q.png">
Below is the second MX record:
<img alt="Mailgun: second MX record for a new domain" src="https://i.imgur.com/nsqyF5V.png">
After you've added two TXT and two MX records, you can check and verify them by clicking the "Verify DNS Records" button.
<img alt="Mailgun: checking TXT and MX records for a new domain" src="https://i.imgur.com/Dfoa8bi.png">
Lastly, add CNAME record.
<img alt="Mailgun: adding CNAME record for a new domain" src="https://i.imgur.com/mbPG4E1.png">
You may see a warning icon on the left of the CNAME record. You don't need to worry about that, cause what [official documentation says](https://developers.cloudflare.com/ssl/edge-certificates/additional-options/total-tls/error-messages) about it:
> If you recently [added your domain](https://developers.cloudflare.com/fundamentals/setup/manage-domains/add-site/) to Cloudflare - meaning that your zone is in a [pending state](https://developers.cloudflare.com/dns/zone-setups/reference/domain-status/) - you can often ignore this warning.
> Once most domains becomes **Active**, Cloudflare will automatically issue a Universal SSL certificate, which will provide SSL/TLS coverage and remove the warning message.
After adding a CNAME record, you can check and verify it again by clicking the second "Verify DNS Records" button.
<img alt="Mailgun: checking CNAME record for a new domain" src="https://i.imgur.com/Xm58Ziq.png">
If you have added all 5 records on the Cloudflare successfully, after clicking the verifying button, Mailgun will automatically redirect you to the "_Overview_" page.
<img alt="Mailgun: 2 TXT, 2 MX and 1 CNAME records added for a new domain" src="https://i.imgur.com/bULjKsQ.png">
It means you're ready to add a Sending API key on Mailgun.
### Mailgun: Sending API key & SMPT User
Go to "_Sending_" -> "_Domain Settings_" page. Choose the "_Sending API keys_" tab at the top. Probably you won't see any API keys there. You just need to create a new Sending API key. Click "Add sending key" from the top right corner, and in the popup fill the name of the key you about to create.
<img alt="Mailgun: creating a Sending API key" src="https://i.imgur.com/FqBEgYp.png">
After pressing "Create sending key", you'll get the secret API key that you need to copy and save somewhere safe. After saving the key, you can just close the popup.
You'll see the created key listed:
<img alt="Mailgun: Sending API key created" src="https://i.imgur.com/bjneG7e.png">
You also need to create a new SMTP user in Mailgun dashbaord.
Go to "_Sending_" -> "_Domain Settings_" page. Choose the "_SMTP credentials_" tab at the top and press "Add new SMTP user" button on the top left corner. It will open up a popup. Type user credentials there. In our case I'll create a user with the name "_email_". It will be like a login for your email on Gmail.
<img alt="Mailgun: creating SMTP user" src="https://i.imgur.com/w1XQAiW.png">
Once you create an SMTP user in Mailgun, you'll see it listed and a password for that user will be generated automatically. To get this password, copy it by clicking the "Copy" button in the pop-up notification in the lower right corner.
<img alt="Mailgun: SMTP user created" src="https://i.imgur.com/sc3o62Z.png">
Keep this in a safe place for future use. You will need this login and password to authenticate on Gmail.
You are now ready to set up email configurations with your email provider. In our case, we will do this in Gmail.
Open your Gmail account in your desktop browser and go to Settings by clicking the settings icon in the top right corner and click the "See all settings" button.
<img alt="Mailgun: new domain is verified" src="https://i.imgur.com/CIffzot.png">
### Gmail Authentication with Mailgun SMTP Server
In the Gmail settings page choose the "_Accounts and Import_" tab and click on the "Add another email address" from the "_Send mail as_" section:
<img alt="Gmail: Settings" src="https://i.imgur.com/TmeLLP9.png">
It will open a popup for the authentication. Use the login and the password you just got by creating an SMTP user on Mailgun. Make sure to fill out the credentials correctly.
<img alt="Gmail: authenticate a new user using a created SMTP server on Mailgun" src="https://i.imgur.com/olxBStq.png">
Submit the form by clicking the "Add Account" button.
It probably will ask you to save the username/password in your browser. It's up to you.
And the last important thing here, that it will ask you to verify adding an account.
<img alt="Gmail: authentication confirmation for a new user" src="https://i.imgur.com/WcOZGMA.png">
For the verification, the confirmation email will be sent to your primary email.
<img alt="Gmail: authentication verification email" src="https://i.imgur.com/SpwMVc4.png">
You can either use the confirmation code to verify it using the pop-up window or simply follow the link provided in the confirmation email.
In this case, we'll click on a link that will open the page, where will be asked to confirm. Click on "Confirm" and simply close the previously opened pop-up window without worrying.
<img alt="Gmail: verifying the authentication" src="https://i.imgur.com/3nVbH1T.png">
Now you're ready to send and receive emails from the custom email you just created.
For sending an email from the custom email, you just need to choose that email as a sender email:
<img alt="Gmail: sending emails" src="https://i.imgur.com/gMkmDKW.png">
**That's it!**
An additional thing that may be useful to you is that you can set the custom email address you just created as the default address for sending emails from Gmail.
You can set this on the settings page in the "_Send mail as_" section:
<img alt="Gmail: Settings (default sender)" src="https://i.imgur.com/bOPXRmt.png">
I hope this guide will be a good resource for setting up your custom email.

Laravel's [Route Model Binding] (https://laravel.com/docs/11.x/routing#route-model-binding) stands as a cornerstone feature, streamlining the interaction between routes and models within your application. It offers a seamless mechanism to automatically inject model instances into your routes based on specified parameters. This feature not only enhances code readability but also boosts developer productivity by eliminating the need for manual model retrieval.
## Understanding Route Model Binding
At its core, Route Model Binding simplifies the process of retrieving model instances by associating them directly with route parameters. Consider a scenario where you're building a blogging platform using Laravel. You have a Post model representing individual blog posts, and you wish to create routes to display these posts based on their IDs.
**Implementation Example**
Let's delve into a practical example to grasp the essence of Route Model Binding. In your routes/web.php file, define a route to showcase individual posts:
```
Route::get('/posts/{post}', 'PostController@show');
```
Here, {post} serves as a route parameter signifying the ID of the post.
Next, within your PostController, craft the show method as follows:
```
public function show(Post $post)
{
return view('posts.show', ['post' => $post]);
}
```
Observe that the show method takes a parameter $post, type-hinted with the Post model. Laravel intelligently resolves this parameter, automatically injecting the corresponding Post model instance based on the value of the {post} route parameter.
Now you can access the posts:
```
http://localhost:8000/posts/1
```
**Streamlining Controller Logic**
Through Route Model Binding, Laravel obviates the need for manual model retrieval within controller methods. This not only declutters your code but also enhances its expressiveness and maintainability. By seamlessly integrating model instances into your controllers, Laravel empowers developers to focus on implementing business logic rather than grappling with mundane data retrieval tasks.
**Conclusion**
In conclusion, Laravel's Route Model Binding emerges as a powerful tool for simplifying controller logic and enhancing developer productivity. By seamlessly bridging routes and models, it facilitates cleaner, more expressive code, thereby fostering a more enjoyable and efficient development experience. Embrace Route Model Binding in your Laravel projects to unlock its full potential and streamline your application's architecture.

1,824,373 | Role of Custom MVP Software Development for Small Business | Developing software in a flash is almost like a dream. Big sharks had to wait for years to deliver... | 0 | 2024-04-16T12:06:41 | https://dev.to/jessicab/role-of-custom-mvp-software-development-for-small-business-3lp6 | mvpsoftwaredevelopment, customsoftwaredevelopment, softwaredevelopment | Developing software in a flash is almost like a dream. Big sharks had to wait for years to deliver the product that we love now. Take a look at Facebook; it didn't achieve the flair overnight that it has today.
This extended timeline can pose stress to the limited budget and resources of small businesses. Therefore, achieving small goals successfully is the most practical decision for startups.
This is where the Minimum Viable Product (MVP) truly shines!
MVP is the first usable version of the software with enough features to understand if people actually like it. Thus, startups with restrained budgets can see if they can fly before building the entire airplane.
Sounds exciting, right? So, let's explore custom MVP software development before making a serious decision.
## What is an MVP in software development?
MVP is a strategic approach in software development where businesses provide a simplified version of the product. The primary goal is to quickly bring the software to market and gather valuable customer feedback.
**The 3 aspects of MVP:**
Below are the 3 core aspects that make an MVP-
**Key functionality**
Only the necessary features are required to address the primary requirements of the target audience.
**User feedback**
Early release to the market to see if the consumers like the product and their feedback to improve the product.
**Iterative development**
The development cycle is a continuous process of improvement based on user feedback and demand.
## Understanding the needs of small businesses: Why MVP is important
Check out the limitations of a growing business to understand its need for custom MVP software development.
### Budget constraints
Financial resources are often inadequate for startups. It's no different for [custom software development for small businesses](https://www.unifiedinfotech.net/services/custom-software-development/). The cost of creating a complete software application might be high. MVP enables companies to test the market and verify their ideas without going over budget by allowing them to release a rudimentary version of their product at a cheap cost.
### Limited resource
Small enterprises frequently have resource limitations, such as a shortage of personnel and technological know-how. Minimum Viable Product concentrates on key features a software needs to release in the market. It enables companies to make better and more effective use of the resources at their fingertips.
### Scalability
Scalability is an essential consideration for startups that want to expand. MVP makes scalability easier by offering a base upon which growth in the company may be built.

Introduction In the... | 0 | 2024-04-16T13:59:48 | https://dev.to/chintanonweb/designing-for-tomorrow-the-future-proof-benefits-of-flexbox-and-css-grid-9a9 | html, css, webdev, ui | # Why Should UI Designers Understand Flexbox and CSS Grid?
## Introduction
In the ever-evolving landscape of web design, staying ahead of the curve is imperative for UI designers. Two key technologies that have revolutionized the way we layout and structure web pages are Flexbox and CSS Grid. Understanding these tools not only enhances a designer's skill set but also opens up a world of possibilities for creating responsive and visually appealing layouts. Let's delve into why UI designers should invest their time in mastering Flexbox and CSS Grid.
## The Power of Flexbox and CSS Grid
Flexbox and CSS Grid offer powerful layout mechanisms that enable designers to create complex and responsive layouts with ease. Unlike traditional methods like floats and positioning, which often result in messy and hard-to-maintain code, Flexbox and CSS Grid provide a cleaner and more intuitive approach to layout design.
### Flexbox: A Flexible Approach
Flexbox is a one-dimensional layout model that allows elements within a container to be dynamically arranged based on available space. It offers precise control over the alignment, distribution, and order of elements, making it ideal for creating responsive designs.
Let's consider a common scenario: creating a navigation bar with Flexbox.
```css
.navbar {
display: flex;
justify-content: space-between;
align-items: center;
}
.nav-item {
margin: 0 10px;
}
```
In this example, the `.navbar` container uses `display: flex` to enable Flexbox layout. By setting `justify-content: space-between`, the navigation items are evenly distributed along the main axis, while `align-items: center` ensures they are vertically centered within the container.
### CSS Grid: A Grid-Based Layout System
CSS Grid introduces a two-dimensional grid system, allowing designers to create complex layouts with rows and columns. It provides precise control over the placement and sizing of elements, making it perfect for building intricate page structures.
Let's create a simple grid layout using CSS Grid:
```css
.container {
display: grid;
grid-template-columns: 1fr 2fr;
grid-gap: 20px;
}
.item {
background-color: #f0f0f0;
padding: 20px;
}
```
In this example, the `.container` element is defined as a grid container with two columns of equal width (`1fr` and `2fr`) using `grid-template-columns`. The `grid-gap` property adds spacing between grid items, enhancing readability and aesthetics.
## Why UI Designers Should Embrace Flexbox and CSS Grid
### Seamless Responsiveness
One of the key advantages of Flexbox and CSS Grid is their innate ability to create responsive layouts without the need for complex media queries. By leveraging features like flex-grow, flex-shrink, and auto-placement, designers can ensure that their designs adapt seamlessly to various screen sizes and devices.
### Simplified Codebase
Gone are the days of convoluted CSS hacks to achieve seemingly simple layouts. Flexbox and CSS Grid promote cleaner, more maintainable code by eliminating the need for excessive nesting and floats. This not only streamlines the development process but also reduces the likelihood of bugs and compatibility issues.
### Enhanced Productivity
By mastering Flexbox and CSS Grid, UI designers can work more efficiently, iterating on designs rapidly and experimenting with different layouts with ease. The intuitive nature of these layout models empowers designers to focus on creativity rather than wrestling with the intricacies of CSS positioning.
### Future-Proofing Designs
As the web continues to evolve, it's essential for UI designers to future-proof their skills. Flexbox and CSS Grid represent the future of layout design, with widespread support across modern browsers and a growing community of developers contributing to their advancement. By embracing these technologies early on, designers can stay ahead of the curve and remain relevant in an ever-changing industry.
## FAQs
### Q: Are Flexbox and CSS Grid mutually exclusive, or can they be used together?
A: Flexbox and CSS Grid are complementary technologies and can be used together to create complex layouts. While Flexbox excels at one-dimensional layouts, CSS Grid is ideal for two-dimensional layouts, making them a powerful combination for modern web design.
### Q: Do I need to abandon traditional layout methods like floats and positioning?
A: While Flexbox and CSS Grid offer superior layout capabilities, there may still be scenarios where traditional methods are appropriate. However, embracing Flexbox and CSS Grid can significantly simplify your workflow and improve the maintainability of your codebase.

If you like these kinds of analysis, you should subscribe to the [AImodels.fyi newsletter](https://aimodels.substack.com) or follow me on [Twitter](https://twitter.com/mikeyoung44).*
## Overview
- The paper presents a novel architecture called Megalodon, which enables efficient pretraining and inference of large language models (LLMs) with unlimited context length.
- Megalodon builds upon the [Moving Average Equipped Gated Attention (Mega)](https://aimodels.fyi/papers/arxiv/enhancing-inference-efficiency-large-language-models-investigating) architecture, which addresses the challenges of long-context learning in LLMs.
- The authors demonstrate that Megalodon achieves state-of-the-art performance on a range of long-context tasks, while also being more computationally efficient compared to existing approaches.
## Plain English Explanation
Megalodon is a new type of large language model (LLM) that can handle very long input texts, unlike traditional LLMs that struggle with long contexts. [LLMs are AI systems that are trained on massive amounts of text data to generate human-like language.](https://aimodels.fyi/papers/arxiv/leave-no-context-behind-efficient-infinite-context)
The key innovation in Megalodon is its use of a technique called [Moving Average Equipped Gated Attention (Mega)](https://aimodels.fyi/papers/arxiv/enhancing-inference-efficiency-large-language-models-investigating). This allows the model to efficiently process long input texts without losing important information.
By using Mega, Megalodon can perform better on tasks that require understanding of long-form content, such as summarizing lengthy documents or answering questions about complex topics. [Traditional LLMs often have difficulty maintaining context and coherence over long stretches of text.](https://aimodels.fyi/papers/arxiv/long-context-llms-struggle-long-context-learning)
The authors show that Megalodon outperforms other state-of-the-art models on various long-context benchmarks, while also being more efficient in terms of computational resources. This means Megalodon can be deployed on a wider range of devices and applications, including those with limited processing power.
## Technical Explanation
The paper introduces a new architecture called Megalodon, which builds upon the [Moving Average Equipped Gated Attention (Mega)](https://aimodels.fyi/papers/arxiv/enhancing-inference-efficiency-large-language-models-investigating) mechanism. Mega is designed to enhance the efficiency of large language models (LLMs) during inference by introducing a moving average operation into the attention mechanism.
Megalodon further extends Mega by incorporating techniques to enable efficient pretraining and inference of LLMs with unlimited context length. The key components of Megalodon include:
1. **Mega Attention**: The use of Mega attention, which replaces the standard attention mechanism in Transformer-based models. Mega attention maintains a moving average of past attention weights, allowing the model to efficiently aggregate information from long contexts.
2. **Chunked Attention**: To handle arbitrarily long input sequences, Megalodon splits the input into smaller chunks and processes them in parallel, with attention computed within and across chunks.
3. **Efficient Pretraining**: The authors propose a pretraining strategy that leverages a combination of masked language modeling and a novel cross-attention objective to enable efficient learning of long-range dependencies.
The paper evaluates Megalodon on a range of long-context benchmarks, including [LLOCO](https://aimodels.fyi/papers/arxiv/lloco-learning-long-contexts-offline), [LLM2Vec](https://aimodels.fyi/papers/arxiv/llm2vec-large-language-models-are-secretly-powerful), and others. The results demonstrate that Megalodon achieves state-of-the-art performance on these tasks while being more computationally efficient compared to previous approaches.
## Critical Analysis
The paper presents a promising solution to the challenge of processing long input texts in large language models. By leveraging the Mega attention mechanism and other techniques, Megalodon is able to efficiently handle long-context tasks that traditional LLMs struggle with.
However, the paper does not address some potential limitations of the Megalodon approach:
1. **Generalization beyond benchmarks**: While Megalodon performs well on the specific long-context benchmarks evaluated, it is unclear how it would generalize to a broader range of real-world applications that may have different characteristics and requirements.
2. **Memory and storage overhead**: The paper does not provide a detailed analysis of the memory and storage requirements of Megalodon, which could be a concern for deployment on resource-constrained devices.
3. **Interpretability and explainability**: As with many complex neural network architectures, the inner workings of Megalodon may be difficult to interpret and explain, which could limit its adoption in domains that require high levels of transparency.
Further research and evaluation would be needed to address these potential limitations and to more fully understand the strengths and weaknesses of the Megalodon approach.
## Conclusion
The Megalodon architecture presented in this paper represents a significant advancement in the field of large language models, enabling efficient pretraining and inference with unlimited context length. By building upon the Mega attention mechanism, Megalodon achieves state-of-the-art performance on long-context benchmarks while being more computationally efficient than previous approaches.
This research has important implications for a wide range of applications that require understanding and generation of long-form text, such as document summarization, question answering, and knowledge-intensive tasks. As language models continue to grow in size and complexity, innovations like Megalodon will be crucial for ensuring these models can be deployed effectively and efficiently in real-world settings.

## Overview
- Optimization is a common task, but traditional gradient-based methods have limitations when gradients are not available.
- The paper proposes a new approach called "Optimization by PROmpting" (OPRO) that uses large language models (LLMs) as optimizers, where the optimization task is described in natural language.
- OPRO generates new solutions iteratively, evaluates them, and adds them to the prompt for the next step.
- The authors demonstrate OPRO's effectiveness on linear regression, traveling salesman, and prompt optimization problems, showing significant improvements over human-designed prompts.
## Plain English Explanation
Optimization is a fundamental problem that arises in many real-world situations, such as [finding the best route for a delivery truck](https://aimodels.fyi/papers/arxiv/automatic-prompt-selection-large-language-models) or [selecting the most effective prompts for a language model](https://aimodels.fyi/papers/arxiv/language-model-prompt-selection-via-simulation-optimization). Traditional optimization methods that rely on calculating gradients can work well, but they struggle when gradients are not available, which is common in many practical applications.
To address this, the researchers propose a new approach called "Optimization by PROmpting" (OPRO). The key idea is to use powerful [large language models (LLMs)](https://aimodels.fyi/papers/arxiv/cseprompts-benchmark-introductory-computer-science-prompts) as the optimizers, where the optimization task is described in natural language. In each optimization step, the LLM generates new candidate solutions based on the prompt, which contains information about the previously generated solutions and their values. These new solutions are then evaluated, and the best ones are added to the prompt for the next optimization step.
The researchers demonstrate OPRO's effectiveness on several problems, including [linear regression](https://aimodels.fyi/papers/arxiv/llm-rec-personalized-recommendation-via-prompting-large) and the [traveling salesman problem](https://aimodels.fyi/papers/arxiv/large-language-models-are-good-prompt-learners). They also show that OPRO can be used to optimize the prompts themselves, finding instructions that significantly outperform human-designed prompts on challenging language model tasks.
## Technical Explanation
The key innovation in this work is the use of large language models (LLMs) as optimization engines, where the optimization task is described in natural language. This approach, called "Optimization by PROmpting" (OPRO), iteratively generates new candidate solutions based on the current prompt, evaluates them, and adds the best ones to the prompt for the next iteration.
In each optimization step, the LLM takes the current prompt, which includes information about the previously generated solutions and their values, and generates new candidate solutions. These new solutions are then evaluated, and the best ones are added to the prompt for the next step. This process continues until a stopping criterion is met, such as a maximum number of iterations or a target objective value.
The researchers demonstrate OPRO's effectiveness on several problems, including linear regression, the traveling salesman problem, and prompt optimization for language models. In the prompt optimization task, they show that the best prompts found by OPRO can outperform human-designed prompts by up to 8% on the GSM8K benchmark and up to 50% on the more challenging Big-Bench Hard tasks.
## Critical Analysis
One potential limitation of the OPRO approach is that it relies on the ability of the LLM to generate high-quality candidate solutions based on the current prompt. If the LLM struggles to understand the optimization problem or to generate promising new solutions, the optimization process may not converge to a good result. Additionally, the authors note that OPRO can be computationally expensive, as each optimization step requires running the LLM to generate new solutions.
Another concern is the need for careful prompt engineering to ensure that the LLM understands the optimization problem correctly. If the prompt is not well-designed, the LLM may generate irrelevant or suboptimal solutions, leading to poor optimization performance.
Despite these potential limitations, the OPRO approach represents an interesting and novel application of large language models, demonstrating their potential as powerful optimization tools. The authors have provided an open-source implementation of OPRO, which should encourage further research and experimentation in this area.
## Conclusion
The paper presents a novel approach called "Optimization by PROmpting" (OPRO) that leverages the power of large language models (LLMs) to optimize complex problems where traditional gradient-based methods may struggle. By describing the optimization task in natural language and iteratively generating and evaluating candidate solutions, OPRO has been shown to outperform human-designed prompts on a range of tasks, including prompt optimization for language models.
While OPRO has some potential limitations, such as the need for careful prompt engineering and computational expense, the authors' work highlights the exciting potential of using LLMs as optimization tools. As language models continue to advance, the OPRO approach may become an increasingly valuable tool for tackling a wide range of optimization challenges in the real world.

Please follow the updated stackblitz... | 0 | 2024-04-17T18:40:08 | https://dev.to/kstulgys/how-to-generate-stylish-pdfs-and-images-with-tailwind-css-in-your-application-15e7 | **UPDATE 2022-05-22:** tailwindstream api got some improvements. Please follow the updated stackblitz example that you can find on [tailwindstream.io ](https://tailwindstream.io )
Transform your application into a powerhouse for creating stunning documents and images using HTML styled with Tailwind CSS. In this guide, we’ll walk you through the process of integrating a powerful document generation API from [tailwindstream.io](https://tailwindstream.io), showcasing how you can enhance your application's functionality with high-quality, styled document outputs.
## Why Use Tailwind CSS for Document Generation?
Tailwind CSS is renowned for its utility-first approach, making it an excellent choice for developers looking to implement custom styles quickly without leaving the comfort of their HTML. By using Tailwind CSS with the [tailwindstream.io](https://tailwindstream.io) API, developers can ensure that their digital documents carry the same level of precision and customisation as their web interfaces.
## **Integrating the** [**tailwindstream.io**](https://tailwindstream.io) **API**
Our chosen API isn't just any document generation tool; it excels by accepting HTML content styled using Tailwind CSS, allowing full utilization of Tailwind's utility classes directly within your documents. Here’s a brief overview of the API capabilities that you can leverage:
* **HTML Content**: Embed HTML with Tailwind CSS for dynamic styling.
* **Format Specification**: Supports various paper sizes such as A4, Letter, etc.
* **Output Options**: Generate documents in PDF, PNG, JPEG, or WebP formats.
* **Custom Dimensions**: Control output dimensions and scaling to ensure your documents look perfect.
Below is a basic React component setup that utilises the [**tailwindstream.io**](https://tailwindstream.io) API to generate a document:
```typescript
import { useState } from 'react';
const sampleHtml = `
<figure class="md:flex bg-slate-100 rounded-xl p-8 md:p-0 dark:bg-slate-800">
<img class="w-24 h-24 md:w-48 md:h-auto md:rounded-none rounded-full mx-auto object-cover" src="https://tailwindcss.com/_next/static/media/sarah-dayan.de9b3815.jpg" alt="" width="384" height="512">
<div class="pt-6 md:p-8 text-center md:text-left space-y-4">
<blockquote>
<p class="text-lg font-medium">
“Tailwind CSS is the only framework that I've seen scale
on large teams. It’s easy to customize, adapts to any design,
and the build size is tiny.”
</p>
</blockquote>
<figcaption class="font-medium">
<div class="text-sky-500 dark:text-sky-400 font-bold">
Sarah Dayan
</div>
<div class="text-slate-700 dark:text-slate-500">
Staff Engineer, Algolia
</div>
</figcaption>
</div>
</figure>
`;
function App() {
const [error, setError] = useState('');
const [downloading, setDownloading] = useState(false);
const [payload, setPayload] = useState<BodyPayload>({
html: sampleHtml,
output: 'pdf',
});
const setHtml = (htmlContent: string) => {
setPayload({ ...payload, html: htmlContent });
};
const setOutput = (outputFormat: BodyPayload["output"]) => {
setPayload({ ...payload, output: outputFormat });
};
const download = async () => {
setDownloading(true);
try {
const response = await requestDownload(payload);
if (response.error) {
setError(response.error);
setDownloading(false);
} else if (response.requestId) {
downloadWithRetry(response.requestId);
}
} catch (error) {
setError('Something went wrong.');
setDownloading(false);
}
};
return (
<div>
<SelectOutput onChange={setOutput} />
<button onClick={download}>{downloading ? 'Downloading...' : `Download .${payload.output}`}</button>
{error && <p>{error}</p>}
<textarea
rows={25}
cols={80}
value={payload.html}
onChange={(e) => setHtml(e.target.value)}
/>
</div>
);
}
export default App;
```
Send a POST request with your styled HTML content to generate the desired file format:
```typescript
const apiUrl = `https://api.tailwindstream.io`;
async function requestDownload(payload: BodyPayload) {
const response = await fetch(apiUrl + '/request', {
method: 'POST',
body: JSON.stringify(payload),
headers: { 'Content-Type': 'application/json' },
});
return await response.json();
}
```
Handle download attempts and retries:
```typescript
const RETRY_INTERVAL_MS = 2500;
async function downloadWithRetry(requestId: string) {
const intervalId = setInterval(async () => {
const response = await fetch(`${apiUrl}/request/${requestId}/download`);
if (response.ok) {
const blob = await response.blob();
downloadToBrowser(blob);
clearInterval(intervalId);
} else {
console.error('Download failed, retrying...');
}
}, RETRY_INTERVAL_MS);
}
```
Document generation might take 2-6 second. This retry logic ensures we download the file when it's ready.
You might ask: what are the options I can pass to the api? Well... here is the typescript definition my friend:
```typescript
type BodyPayload = {
html?: string; // must be undefined if 'template' prop is used
format?: // applicable only for pdf, default a4
| "LETTER"
| "LEGAL"
| "TABLOID"
| "LEDGER"
| "A0"
| "A1"
| "A2"
| "A3"
| "A4"
| "A5"
| "A6"
| "Letter"
| "Legal"
| "Tabloid"
| "Ledger";
output?: "pdf" | "png" | "jpeg" | "webp"; // default pdf
size?: {
scale?: number; // default 2
width?: string | number; // default 210
height?: string | number; // default 297
unit?: "px" | "in" | "cm" | "mm"; // default mm
};
template?: {
html: string; // handlebars dynamic html
data: Record<string, any>; // data for dynamic html
};
};
```

To... | 0 | 2024-05-03T11:02:17 | https://dev.to/pelumisat/creating-my-first-virtual-machine-on-microsoft-azure-1gk4 | azure, devops, cloud, aws |
Hello, I'd like to share with you how I created my first virtual machine on Microsoft Azure. To start, let me briefly explain what virtual machines are. Essentially, virtual machines serve as operating systems or software that mimic physical machines. They make it easier to provision applications, hardware, software, data, and computing power, which is essential for achieving scalability, flexibility, and cost optimization in modern business and computing environments.
**Below is my simple step-by-step process for launching a Windows machine in Azure.**
On the Microsoft Azure dashboard, you can create new resources by clicking on the section highlighted with a red square.
This image displays the variety of resources that can be launched. Click on the Azure virtual machine to initiate the deployment process.
You will be directed to a section where you can customize the virtual machine according to your requirements and assign it a suitable name.
Be sure to specify a region for your resource. An Azure region includes several data centres in one geographic area.
Choose suitable availability zones, which are isolated data centres with independent cooling, power, security, and network resources.
For the virtual machine, select a machine image and choose an operating system. I chose the free tier Windows 11 OS.
Create a secure username and password to access your virtual machine.
To initiate the launch, click on the "Review and Create" tab and then click on the Create button below.
Please wait until the deployment is complete. Afterwards, click "Go to Resource."
Click where you see the virtual machine's public IP address to modify its Idle timeout.
Please set the idle timeout to 15 minutes and navigate back to the previous page.
To configure features for your virtual machine on Azure, please click on the "connect" button.
To start the configuration process, please click on the 'Select' button.
Please wait until the configuration process is complete. Once the process is done, you will see a message that says "configured".
Click the 'Download RDP file' button after completing the configuration.
After downloading the RDP file, simply click on it to start the installation process. Follow the instructions provided to log in using the username and password you previously provided. Once the process is complete, you will have access to your newly created virtual machine. Below, you can find a screenshot of my virtual machine for reference.
Hopefully, you will be able to follow these easy steps to create your virtual machine after reading this article.

1,839,175 | OOP poetry part III - behavioural patterns | what are behavioural patterns in OODesign Behavioural patterns in design patterns are... | 27,210 | 2024-05-01T02:06:16 | https://dev.to/eatyourabstractions/design-pattern-poetry-part-iii-behavioural-1039 | designpatterns, oop | ## what are behavioural patterns in OODesign
Behavioural patterns in design patterns are concerned with communication between objects, how objects collaborate, and how responsibilities are distributed among them. They focus on the interaction patterns between objects and classes, rather than on the structure of the classes or objects themselves.
## List of patterns
- [Chain of responsability](#chain-of-responsability)
- [Command pattern](#command-pattern)
- [Iterator pattern](#iterator-pattern)
- [Mediator pattern](#mediator-pattern)
- [memento pattern](#memento-pattern)
- [Oberserver pattern](#oberserver-pattern)
- [State pattern](#state-pattern)
- [strategy pattern](#strategy-pattern)
- [template method pattern](#template-method-pattern)
- [Visitor pattern](#visitor-pattern)
<a name="chain-of-responsability"></a>
## Chain of responsability
In the world of objects, bound in code's embrace,
Lies a pattern, a concept, with intricate grace.
Chain of Responsibility, its name does declare,
A solution profound, to design's wear and tear.
At its heart, it holds <u>the essence of delegation,</u>
<u>Passing requests along,</u> without hesitation.
When a sender's request, seeks a handler's touch,
The chain springs to action, responding as such.
Imagine a system where commands take flight,
<u>Through layers of objects,</u> to reach their light.
<u>Each link in the chain, bears its own duty,</u>
Handling requests with care, swiftness, and beauty.
For reason it stands, with a purpose so clear,
<u>To decouple senders and receivers, so dear.</u>
Flexibility reigns, as responsibilities flow,
Adapting to changes, with a graceful, agile bow.
In logging systems, it finds its home,
Where messages travel, not alone.
From lowest to highest, or vice versa too,
The chain handles tasks, old and new.
In graphical user interfaces, it takes its place,
Responding to events, with effortless grace.
Buttons and menus, actions abound,
The chain ensures they're properly found.
In software pipelines, it proves its might,
Processing data streams, day and night.
Each link plays its role, in a symphony grand,
Chain of Responsibility, at its command.
In the realm of web servers, where requests flood the gate,
Express.js stands tall, amidst the debate.
With <u>middleware</u> galore, it handles each plea,
Chain of Responsibility, it sets users free.
From parsing requests to serving static files,
Express delegates tasks with practiced smiles.
Routing requests, with paths clear and bright,
Each middleware link, guiding with might.
Authentication, logging, error handling too,
Express.js weaves them seamlessly through.
Each middleware layer, a link in the chain,
Ensuring requests don't fall in vain.
So here's to the pattern, ingenious and bright,
Weaving through systems, like stars in the night.
With elegance it solves, design's intricate chore,
Chain of Responsibility, forevermore.
```typescript
import express, { Request, Response, NextFunction } from 'express';
// Define a middleware function for logging
function loggerMiddleware(req: Request, res: Response, next: NextFunction) {
console.log(`[${new Date().toISOString()}] ${req.method} ${req.path}`);
next(); // Pass control to the next middleware
}
// Define a middleware function for authentication
function authMiddleware(req: Request, res: Response, next: NextFunction) {
const authToken = req.headers.authorization;
if (!authToken || authToken !== 'secret_token') {
return res.status(401).send('Unauthorized');
}
next(); // Pass control to the next middleware
}
// Define a route handler
function homeRouteHandler(req: Request, res: Response) {
res.send('Welcome to the home page!');
}
// Create an Express application
const app = express();
// Register middleware in the chain
app.use(loggerMiddleware);
app.use(authMiddleware);
// Define a route for the home page
app.get('/', homeRouteHandler);
// Start the server
const PORT = 3000;
app.listen(PORT, () => {
console.log(`Server is running on http://localhost:${PORT}`);
});
```
<a name="command-pattern"></a>
## Command pattern
In the vast realm of code, where structures abound,
Lies a pattern of power, with elegance crowned.
Command Design Pattern, its name whispers grace,
A solution profound, to design's complex maze.
At its core, it holds the essence of action,
<u>Encapsulating tasks</u> with flawless traction.
When a request seeks execution's embrace,
The command pattern steps in, with unwavering grace.
Picture a system where commands take flight,
<u>Bound in objects,</u> gleaming with light.
<u>Each command encapsulates an action's delight,</u>
<u>Decoupling sender and receiver in design's sight.</u>
For its purpose it stands, with clarity so clear,
<u>To separate concerns, </u>dispelling design's fear.
Flexibility reigns as tasks are enshrined,
In commands, where elegance and power entwined.
Amidst the realm of React's vibrant domain,
Where state management orchestrates without strain,
Redux, the sage, with its store's noble grace,
Embraces commands in a timeless embrace.
Within its core, actions spring to life,
Commands encapsulated, amidst the strife.
Each action a decree, a change to impart,
In Redux's world, a symphony's start.
As users interact with the UI's array,
Actions echo their intent, clear as day.
From clicks to inputs, each event unfurled,
Triggers a command, in the Redux world.
Through reducers and dispatch, the commands take flight,
Altering state with precision, might.
Each action a ripple, in React's gentle breeze,
Guiding the flow, with effortless ease.
So here's to the pattern, with purpose so grand,
Command Design Pattern, across the land.
In software's tapestry, it weaves its tale,
A masterpiece of design, without fail.
```js
// CounterActions.js
export const ActionTypes = {
INCREMENT: 'INCREMENT',
DECREMENT: 'DECREMENT',
};
// Action creators (commands)
export const increment = () => ({
type: ActionTypes.INCREMENT,
});
export const decrement = () => ({
type: ActionTypes.DECREMENT,
});
// CounterReducer.js
import { ActionTypes } from './CounterActions';
const initialState = {
count: 0,
};
// Reducer function
const counterReducer = (state = initialState, action) => {
switch (action.type) {
case ActionTypes.INCREMENT: // Command: INCREMENT
return {
...state,
count: state.count + 1,
};
case ActionTypes.DECREMENT: // Command: DECREMENT
return {
...state,
count: state.count - 1,
};
default:
return state;
}
};
export default counterReducer;
// Counter.js
import React, { useReducer } from 'react';
import counterReducer from './CounterReducer';
import { increment, decrement } from './CounterActions';
const Counter = () => {
// Initialize state and dispatch function using useReducer hook
const [state, dispatch] = useReducer(counterReducer, { count: 0 });
// Command execution: Dispatching actions
const handleIncrement = () => {
dispatch(increment()); // Command: increment
};
const handleDecrement = () => {
dispatch(decrement()); // Command: decrement
};
return (
<div>
<h1>Counter: {state.count}</h1>
{/* Buttons triggering commands */}
<button onClick={handleIncrement}>Increment</button>
<button onClick={handleDecrement}>Decrement</button>
</div>
);
};
export default Counter;
```
<a name="iterator-pattern"></a>
## Iterator pattern
In the world of data, where structures abound,
A pattern emerges, with purpose profound.
Iterator Pattern, its essence does gleam,
Navigating collections like a serene dream.
At its heart lies the quest to explore,
<u>Traversing sequences,</u> from ceiling to floor.
When data beckons, and elements call,
Iterator responds, ensuring naught shall stall.
Imagine a journey through lists long and wide,
With each step traversed, with grace as our guide.
<u>From start to end, or reverse if we please,</u>
Iterator leads, with consummate ease.
Its purpose to abstract, traversal's chore,
<u>From arrays to trees, and even more.</u>
Flexibility reigns, as it adapts with flair,
<u>To various structures, without a care.</u>
In for loops, it finds its natural place,
Where iteration flows, at a steady pace.
Looping through arrays, in languages vast,
Iterator ensures no element's surpassed.
In the realm of streams, <u>both finite and grand,</u>
Iterator's hand guides across the land.
From reading files to parsing streams,
Iterator orchestrates, fulfilling our dreams.
So here's to the pattern, in data's embrace,
Iterator Pattern, with elegance and grace.
In software's symphony, it plays its part,
A maestro of traversal, with a beating heart.
```ts
// Define an interface for the iterator
interface Iterator<T> {
next(): { value: T, done: boolean };
}
// Define an iterable collection for Fibonacci numbers
class FibonacciSequence implements Iterable<number> {
[Symbol.iterator](): Iterator<number> {
let a = 0;
let b = 1;
// Implement the next method of the iterator
const next = (): { value: number, done: boolean } => {
const value = a;
a = b;
b = value + b;
return { value, done: false };
};
return { next };
}
}
// Example usage
const fibonacciSequence = new FibonacciSequence();
const iterator = fibonacciSequence[Symbol.iterator]();
// Print the first 10 Fibonacci numbers
for (let i = 0; i < 10; i++) {
const result = iterator.next();
console.log(result.value); // Output: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34
}
```
<a name="mediator-pattern"></a>
## Mediator pattern
In the world of software, where systems intertwine,
There lies a pattern, with a purpose divine.
Mediator, its name, a conductor of grace,
Bringing harmony to every place.
At its core, it serves to mediate,
<u>Between components, a bridge so great.</u>
With elegance and finesse, it orchestrates,
Communication between disparate states.
Imagine a world where chaos reigns,
Components scattered, with no chains.
Mediator steps in, with a calming embrace,
Bringing order to the chaotic space.
Consider a complex form, with fields galore,
Each input, a component, longing to explore.
But how do they converse, how do they share,
The data they hold, with such care?
Enter the Mediator, with its guiding light,
<u>Centralizing state,</u> keeping components in sight.
Through events and callbacks, it fosters a link,
Between form elements, without a kink.
From Backbone to React, and frameworks in between,
Mediator's touch can always be seen.
<u>Facilitating communication, without fuss,</u>
Bringing cohesion to applications, without muss.
So here's to the Mediator, so noble and grand,
A pattern that brings order to every land.
In software's symphony, it plays its part,
Bringing harmony and unity from the start.
```js
import React, { createContext, useContext, useState } from 'react';
// Define a Context to act as the Mediator
const DataContext = createContext();
// Define a DataProvider component to manage state and act as the Mediator
const DataProvider = ({ children }) => {
// State variable managed by the DataProvider
const [data, setData] = useState('Initial data');
// Method to update data
const updateData = (newData) => {
setData(newData);
};
// Context value containing data and methods to update it
const contextValue = {
data,
updateData,
};
return <DataContext.Provider value={contextValue}>{children}</DataContext.Provider>;
};
// Custom hook to access the DataContext
const useDataContext = () => useContext(DataContext);
// Child component consuming the DataContext and displaying the data
const DisplayComponent = () => {
// Access context variable using custom hook
const { data } = useDataContext();
return <p>Data from context: {data}</p>;
};
// Child component consuming the DataContext and updating the data
const UpdateComponent = () => {
// Access context variable and update method using custom hook
const { data, updateData } = useDataContext();
// Handler for updating data
const handleUpdate = () => {
const newData = 'Updated data';
updateData(newData); // Call the updateData method from the context
};
return (
<div>
<p>Data from context: {data}</p>
<button onClick={handleUpdate}>Update Data</button>
</div>
);
};
// Parent component providing the DataContext to its children
const ParentComponent = () => {
return (
<DataProvider>
<div>
<h2>Parent Component</h2>
<p>This component provides data to its children through the DataContext.</p>
<DisplayComponent /> {/* Child component displaying the data */}
<UpdateComponent /> {/* Child component updating the data */}
</div>
</DataProvider>
);
};
export default ParentComponent;
```
<a name="memento-pattern"></a>
## memento pattern
In the land where code takes flight,
Lies a pattern of memory, shining bright.
Known as Memento, its purpose grand,
To capture states with a gentle hand.
When objects dance with transient grace,
And their states must leave no trace,
<u>Memento whispers, "Fear not, dear friend,</u>
<u>For I shall hold your states till journey's end."</u>
<u>In times of undo, where mistakes do roam,</u>
Memento's embrace brings solace home.
<u>With each command to rewind or revise,</u>
<u>It restores the past before our eyes.</u>
In editors where text flows free,
Undoing changes is a jubilee.
Memento preserves each edit's story,
Returning text to its former glory.
In games where players quest and fight,
Memento records each hero's plight.
With checkpoints saved at every stage,
Players can rewind to a safer page.
In applications of financial might,
Where transactions move with speed and light,
Memento safeguards each transaction's trail,
Ensuring data integrity shall never fail.
So here's to Memento, steadfast and true,
In the world of patterns, it shines anew.
With its purpose clear and its use cases vast,
It guards our states, ensuring they last.
```ts
// Originator: Represents the text editor
class TextEditor {
private content: string;
constructor() {
this.content = '';
}
// Method to set the content of the text editor
setContent(content: string) {
this.content = content;
}
// Method to get the content of the text editor
getContent(): string {
return this.content;
}
// Method to create a memento (snapshot) of the current state
createMemento(): Memento {
return new Memento(this.content);
}
// Method to restore the state from a memento
restoreFromMemento(memento: Memento) {
this.content = memento.getState();
}
}
// Memento: Represents the snapshot of the state of the text editor
class Memento {
private state: string;
constructor(state: string) {
this.state = state;
}
// Method to get the state from the memento
getState(): string {
return this.state;
}
}
// Caretaker: Manages the history of the text editor's states
class HistoryManager {
private history: Memento[];
private currentIndex: number;
constructor() {
this.history = [];
this.currentIndex = -1;

## Oberserver pattern
In the realm where patterns weave their tale,
Lies one of observation, never frail.
'Tis the Observer, its purpose clear,
<u>To let objects know when changes draw near.</u>
When entities dance in a state of flux,
Observer stands ready, never to duck.
Its eyes keenly watch, its ears attuned,
To signals of change, it's always tuned.
In UIs where buttons click and fields update,
Observer whispers softly, "No need to debate."
It notifies listeners when data's transformed,
Ensuring views reflect the changes performed.
In chatrooms where messages fly,
Observer ensures each user's cry.
It broadcasts updates to all who listen,
Uniting users in a shared vision.
In games where scores rise and heroes fall,
Observer shouts loud, heeding the call.
It notifies players of events unseen,
Guiding them through each digital scene.
In the world of Node.js, Observer takes flight,
Within event-driven architecture, it finds its might.
As Node.js dances in asynchronous glee,
Observer notifies listeners of events, setting data free.
In Vue.js, Observer finds a home,
Within the reactive core, it's free to roam.
With reactivity at its heart, Vue.js shines,
Observer pattern ensures views update in time.
In Node.js, event emitters reign supreme,
From HTTP requests to file streams, it's a dream.
Observer pattern orchestrates the flow,
Notifying subscribers when events bestow.
In Vue.js, components come alive,
As data changes, they strive to thrive.
With Observer pattern, they stay in sync,
Rendering views as states blink.
So here's to Node.js and Vue.js, champions bold,
Implementing Observer, their stories unfold.
In event-driven and reactive lands they dwell,
Observer pattern ensures all is well.
```ts
// Observer interface defining the contract for observers
interface Observer {
update(data: any): void;
}
// Observable (subject) class that emits events to observers
class Observable {
private observers: Observer[] = [];
// Method to subscribe an observer to the observable
subscribe(observer: Observer) {
this.observers.push(observer);
}
// Method to unsubscribe an observer from the observable
unsubscribe(observer: Observer) {
this.observers = this.observers.filter(obs => obs !== observer);
}
// Method to notify all observers when an event occurs
notify(data: any) {
this.observers.forEach(observer => observer.update(data));
}
}
// Concrete observer class implementing the Observer interface
class ConcreteObserver implements Observer {
update(data: any) {
console.log('Received data:', data);
}
}
// Usage example
const observable = new Observable();
const observer1 = new ConcreteObserver();
const observer2 = new ConcreteObserver();
// Subscribe observers to the observable
observable.subscribe(observer1);
observable.subscribe(observer2);
// Notify observers when an event occurs
observable.notify('Event 1');
observable.notify('Event 2');
// Unsubscribe observer1 from the observable
observable.unsubscribe(observer1);
// Notify observers again
observable.notify('Event 3');
```

## State pattern
In the realm of software, where patterns are found,
There's one called State, its purpose profound.
Managing <u>objects in various states</u> they may be,
Guiding their behavior with flexibility.
<u>When objects transition from one state to the next,</u>
State pattern ensures they're never perplexed.
It encapsulates state-specific behavior in classes,
Allowing objects to switch with minimal fuss.
In vending machines, where snacks await,
State pattern controls each coin's fate.
As users insert coins and make their selection,
State pattern governs with flawless direction.
In game development, where characters roam,
State pattern gives them a place to call home.
<u>From "idle" to "running", from "jumping" to "crouching",</u>
State pattern keeps their movements from slouching.
In traffic lights, where signals dictate,
State pattern orchestrates the flow of each rate.
<u>From "red" to "green", from "stop" to "go",</u>
State pattern ensures traffic's ebb and flow.
In the software's expanse, where complexity unfurls,
State pattern maps out the intricate worlds.
<u>From states of "ready" to "waiting" and "done",</u>
Each transition managed, each victory won.
In the realm of eCommerce, where orders take flight,
<u>State pattern tracks them from "placed" to "shipped" in the night.</u>
<u>With states like "processing" and "delivered" in sight,</u>
Smooth transitions ensure customers' delight.
In the domain of gaming, where characters roam,
State pattern guides them to their digital home.
<u>From "idle" to "running", from "attacking" to "flee",</u>
Each state transition ensures the game's flow is free.
In the maze of workflows, where tasks intertwine,
State pattern choreographs each step in line.
<u>From "pending" to "approved", from "rejected" to "complete",</u>
Efficient transitions make processes neat.
Within React's realm, where data is king,
State pattern reigns supreme, like a golden ring.
With each fetch request to the server's domain,
State pattern manages the data's gain.
<u>From "loading" to "success" and "error" in sight, </u>
State pattern orchestrates, ensuring all is right.
As components await data to display,
State pattern handles each state, come what may.
So here's to State pattern, with its purpose clear,
Managing objects' states without fear.
In software's vast landscape, it finds its place,
Guiding objects with elegance and grace.
```js
import React, { useState, useEffect } from 'react';
// Define the possible states for the fetch
const FetchState = {
Loading: 'loading',
Success: 'success',
Error: 'error',
};
// Define the fetch component
const FetchComponent = ({ url }) => {
const [fetchState, setFetchState] = useState({
state: FetchState.Loading,
data: null,
error: '',
});
useEffect(() => {
const fetchData = async () => {
try {
const response = await fetch(url);
const data = await response.json();
setFetchState({ state: FetchState.Success, data, error: '' });
} catch (error) {
setFetchState({ state: FetchState.Error, data: null, error: error.message });
}
};
fetchData();
// Cleanup function
return () => {
// Cleanup logic if needed
};
}, [url]);
return (
<div>
{fetchState.state === FetchState.Loading && <p>Loading...</p>}
{fetchState.state === FetchState.Success && <p>Data: {JSON.stringify(fetchState.data)}</p>}
{fetchState.state === FetchState.Error && <p>Error: {fetchState.error}</p>}
</div>
);
};
// Usage example
const App = () => {
return (
<div>
<h1>Fetch Component Example</h1>
<FetchComponent url="https://jsonplaceholder.typicode.com/posts/1" />
</div>
);
};
export default App;
```

Guiding their behavior with elegant force.
In the heart of the code, where complexity lies,
Strategy pattern simplifies, like clear, open skies.
It encapsulates algorithms with finesse,
<u>Allowing them to vary, adapt, and impress.</u>
When sorting arrays or searching for keys,
Strategy pattern shines, like a cool breeze.
<u>With algorithms swapped at runtime's command,</u>
Complex tasks are tamed, and code becomes grand.
In games where strategies govern each move,
Strategy pattern guides, ensuring they groove.
From AI opponents to player tactics grand,
Dynamic strategies shape the game's hand.
In eCommerce realms where discounts are sought,
Strategy pattern aids, with benefits brought.
From fixed discounts to percentage rates,
Flexible strategies handle the rates.
In user interfaces where validations reign,

From email validations to password checks,
Custom strategies ensure security's specs.
So here's to Strategy, with its purpose clear,
In software's vast landscape, it's held dear.
From sorting algorithms to game AI,
Strategy pattern guides with a knowing eye.
example uno:
```js
const numbers = [4, 2, 5, 1, 3];
// Sort in ascending order using the default comparison
const ascendingOrder = numbers.sort((a, b) => a - b);
console.log(ascendingOrder); // Output: [1, 2, 3, 4, 5]
// Sort in descending order using a custom comparison
const descendingOrder = numbers.sort((a, b) => b - a);
console.log(descendingOrder); // Output: [5, 4, 3, 2, 1]
```
example numero deux(a bit more complex):
```ts
// Define the interface for sorting strategies
interface SortStrategy {
sort(data: any[]): any[];
}
// Define concrete sorting strategies

const middle = Math.floor(arr.length / 2);
const left = arr.slice(0, middle);
const right = arr.slice(middle);
return merge(mergeSort(left), mergeSort(right));
};
return mergeSort(data);
}
}
class SelectionSortStrategy implements SortStrategy {
sort(data: any[]): any[] {
// Selection sort implementation
const selectionSort = (arr: any[]): any[] => {

for (let i = 1; i < len; i++) {
let j = i;
const temp = arr[i];
while (j > 0 && arr[j - 1] > temp) {
arr[j] = arr[j - 1];
j--;
}
arr[j] = temp;
}
return arr;
};
return insertionSort(data.slice());
}
}
// Define the context class
class SortContext {
private strategy: SortStrategy;
constructor(strategy: SortStrategy) {
this.strategy = strategy;
}
// Method to set the sorting strategy
setStrategy(strategy: SortStrategy) {
this.strategy = strategy;
}
// Method to perform sorting using the current strategy
sort(data: any[]): any[] {
return this.strategy.sort(data);
}
}
// Usage example
const data = [7, 2, 5, 1, 3, 9, 4, 6, 8];
const bubbleSort = new BubbleSortStrategy();
const quickSort = new QuickSortStrategy();
const mergeSort = new MergeSortStrategy();

<a name="template-method-pattern"></a>
## template method pattern
In software's realm where patterns dance,
Lies one called Template, with elegance and chance.
With purpose clear, it shapes the flow,
Guiding methods with a steadfast glow.
In the heart of libraries, where frameworks shine,
Template Method pattern orchestrates, a design so fine.
<u>With hooks and lifecycle methods in its hand,</u>
It crafts the structure, like grains of sand.
Mocha, the testing framework of choice,
Relies on Template, with a confident voice.
Test suites and cases, in patterns arrayed,
Execute with precision, like a serenade.
Webpack, the bundler that packs with might,
Utilizes Template, in its flight.
Plugins and loaders, with methods defined,
Extend its capabilities, in a bind.
And in the world of JavaScript's delight,
Template Method pattern shines so bright.
In libraries and frameworks, it finds its place,
Guiding developers with its grace.
```ts
// Abstract class defining the template method
abstract class DataProcessor {
// Template method defining the overall algorithm
process(data: any[]): void {
this.readData(data);
this.transformData(data);
this.writeData(data);
}
// Abstract methods to be implemented by subclasses
abstract readData(data: any[]): void;
abstract transformData(data: any[]): void;
abstract writeData(data: any[]): void;
}
// Concrete subclass implementing the template method
class JSONDataProcessor extends DataProcessor {
readData(data: any[]): void {
console.log('Reading JSON data:', data);
}
transformData(data: any[]): void {
console.log('Transforming JSON data...');
// Perform transformation logic specific to JSON data
}
writeData(data: any[]): void {
console.log('Writing JSON data:', data);
}
}
// Concrete subclass implementing the template method
class CSVDataProcessor extends DataProcessor {
readData(data: any[]): void {
console.log('Reading CSV data:', data);
}
transformData(data: any[]): void {
console.log('Transforming CSV data...');
// Perform transformation logic specific to CSV data
}
writeData(data: any[]): void {
console.log('Writing CSV data:', data);
}
}
// Usage example
const jsonDataProcessor = new JSONDataProcessor();
jsonDataProcessor.process([{ id: 1, name: 'John' }, { id: 2, name: 'Doe' }]);
const csvDataProcessor = new CSVDataProcessor();
csvDataProcessor.process(['1,John', '2,Doe']);
```
<a name="visitor-pattern"></a>
## Visitor pattern
In the tapestry of code, where patterns reside,
Lies one called Visitor, with methods to guide.
With purpose profound, it traverses with grace,
Visiting objects, in a coded embrace.
In compilers and parsers, it finds its abode,
Navigating syntax, along the code road.
Each node in the tree, a visit it pays,
Transforming structures, in myriad ways.
In virtual doms of libraries grand,
Visitor pattern takes a stand.
Traversing elements, with DOM's might,
Manipulating, in the web's light.
In data structures of complex design,
Visitor pattern's use, truly shines.
From trees to graphs, it roams with glee,
Performing tasks, with strategy.
So here's to Visitor, with its journey vast,
Guiding traversals, from first to last.
In software's landscape, it leaves its mark,
A pattern of power, in the coder's arc.
uno:
```js
// Babel Visitor implementation
const babelVisitor = {
// Visits ArrowFunctionExpression nodes
ArrowFunctionExpression(node, state) {
// Transform ArrowFunctionExpression nodes
// For example, we might want to convert arrow functions to regular functions
// (This is just a simplified example)
const newFunctionExpression = {
type: 'FunctionExpression',
params: node.params,
body: node.body,
generator: false,
async: false
};
return newFunctionExpression;
},
// Visits CallExpression nodes
CallExpression(node, state) {
// Transform CallExpression nodes
// For example, we might want to prepend a console.log statement before each function call
// (This is just a simplified example)
const newCallExpression = {
type: 'CallExpression',
callee: {
type: 'MemberExpression',
object: { type: 'Identifier', name: 'console' },
property: { type: 'Identifier', name: 'log' }
},
arguments: [
{ type: 'StringLiteral', value: 'Calling function:', raw: '"Calling function:"' },
node
]
};
return newCallExpression;
}
};
// Babel plugin using the Visitor pattern
const babelPlugin = ({ types: t }) => {
return {
visitor: babelVisitor
};
};
// Using Babel with the plugin
const babel = require('@babel/core');
const inputCode = `const add = (a, b) => { return a + b; }; console.log(add(2, 3));`;
const output = babel.transformSync(inputCode, {
plugins: [babelPlugin]
});
console.log(output.code);
```
dos:
```js
// Visitor for generating HTML markup
class HTMLGeneratorVisitor {
constructor() {
this.html = '';
}
visitParagraph(paragraph) {
this.html += `<p>${paragraph.content}</p>`;
}
visitImage(image) {
this.html += `<img src="${image.src}" alt="${image.alt}">`;
}
visitHyperlink(hyperlink) {
this.html += `<a href="${hyperlink.url}">${hyperlink.text}</a>`;
}
}
// Element representing a paragraph in the document
class ParagraphElement {
constructor(content) {
this.content = content;
}
accept(visitor) {
visitor.visitParagraph(this);
}
}
// Element representing an image in the document
class ImageElement {
constructor(src, alt) {
this.src = src;
this.alt = alt;
}
accept(visitor) {
visitor.visitImage(this);
}
}
// Element representing a hyperlink in the document
class HyperlinkElement {
constructor(url, text) {
this.url = url;
this.text = text;
}
accept(visitor) {
visitor.visitHyperlink(this);
}
}
// Example document
const documentElements = [
new ParagraphElement('This is a paragraph.'),
new ImageElement('image.jpg', 'Image Alt Text'),
new HyperlinkElement('https://example.com', 'Example Website')
];
// Create a visitor instance
const htmlGeneratorVisitor = new HTMLGeneratorVisitor();
// Traverse the document elements using the visitor
documentElements.forEach(element => element.accept(htmlGeneratorVisitor));
// Output the generated HTML
console.log(htmlGeneratorVisitor.html);
/*
<p>This is a paragraph.
</p><img src="image.jpg" alt="Image Alt Text">
<a href="https://example.com">Example Website</a>
*/
```

Java... | 0 | 2024-05-02T10:58:11 | https://dev.to/paulike/if-statements-2m9l | java, programming, learning, beginners | An **if** statement is a construct that enables a program to specify alternative paths of execution. Java has several types of selection statements: one-way **if** statements, two-way **if-else** statements, nested **if** statements, multi-way **if-else** statements, **switch** statements, and conditional expressions.
A one-way **if** statement executes an action if and only if the condition is **true**. The syntax for a one-way **if** statement is:
```
if (boolean-expression) {
statement(s);
}
```
The flowchart illustrates how Java executes the syntax of an **if** statement. A _flowchart_ is a diagram that describes an algorithm or process, showing the steps as boxes of various kinds, and their order by connecting these with arrows. Process operations are represented in these boxes, and arrows connecting them represent the flow of control. A diamond box denotes a Boolean condition and a rectangle box represents statements.
If the **boolean-expression** evaluates to **true**, the statements in the block are executed. As an example, see the following code:
```
if (radius >= 0) {
area = radius * radius * PI;
System.out.println("The area for the circle of radius " +
radius + " is " + area);
}
```
The flowchart of the preceding statement is shown in Figure b above. If the value of **radius** is greater than or equal to **0**, then the **area** is computed and the result is displayed; otherwise, the two statements in the block will not be executed. The **boolean-expression** is enclosed in parentheses. For example, the code in (a) is wrong. It should be corrected, as shown in (b).
The block braces can be omitted if they enclose a single statement. For example, the following statements are equivalent.
Omitting braces makes the code shorter, but it is prone to errors. It is a common mistake to forget the braces when you go back to modify the code that omits the braces.
Here's a program that prompts the user to enter an integer. If the number is a multiple of **5**, the program displays **HiFive**. If the number is divisible by **2**, it displays **HiEven**.

1,840,583 | BlenderAlchemy: Editing 3D Graphics with Vision-Language Models | BlenderAlchemy: Editing 3D Graphics with Vision-Language Models | 0 | 2024-05-02T12:10:06 | https://aimodels.fyi/papers/arxiv/blenderalchemy-editing-3d-graphics-vision-language-models | machinelearning, ai, beginners, datascience | *This is a Plain English Papers summary of a research paper called [BlenderAlchemy: Editing 3D Graphics with Vision-Language Models](https://aimodels.fyi/papers/arxiv/blenderalchemy-editing-3d-graphics-vision-language-models). If you like these kinds of analysis, you should subscribe to the [AImodels.fyi newsletter](https://aimodels.substack.com) or follow me on [Twitter](https://twitter.com/mikeyoung44).*
## Overview
- BlenderAlchemy is a novel system that allows users to edit 3D graphics using vision-language models
- The system takes an existing 3D scene and lets users modify it by describing the desired changes in natural language
- BlenderAlchemy then uses a combination of computer vision and language models to understand the user's intent and update the 3D scene accordingly
## Plain English Explanation
BlenderAlchemy is a new way to edit and create 3D graphics using language instead of traditional tools. Typically, making changes to a 3D scene requires specialized software and technical skills. With BlenderAlchemy, you can just describe what you want to change using normal words and sentences, and the system will figure out how to update the 3D model for you.
For example, you could say "Make the chair taller and change its color to blue." BlenderAlchemy would then use artificial intelligence to understand your request, identify the chair object in the 3D scene, and automatically modify its height and color accordingly. This allows people with little 3D modeling experience to easily customize and create 3D content by describing their ideas in plain language.
The key innovation in BlenderAlchemy is the combination of computer vision techniques to recognize 3D objects and understand their properties, with large language models that can interpret natural language instructions. By bringing these two AI capabilities together, the system can bridge the gap between how humans think about 3D design (in terms of natural language) and how 3D modeling software actually works under the hood.
## Technical Explanation
The BlenderAlchemy system leverages recent progress in [vision-language models](https://aimodels.fyi/papers/arxiv/harnessing-power-large-vision-language-models-synthetic) to enable 3D editing via natural language input. Given an existing 3D scene, the system first uses a [computer vision model](https://aimodels.fyi/papers/arxiv/from-pixels-to-graphs-open-vocabulary-scene) to understand the objects, materials, and relationships present in the scene.
This 3D scene understanding is then combined with a large [language model](https://aimodels.fyi/papers/arxiv/enhancing-interactive-image-retrieval-query-rewriting-using) that can interpret the user's natural language instructions. The language model maps the textual description to the relevant 3D elements, and outputs a series of actions to modify the scene accordingly.
For example, if the user says "Make the chair taller and change its color to blue," the system would:
1. Use computer vision to identify the chair object in the 3D scene
2. Analyze the user's language to understand the requested changes (increase height, change color to blue)
3. Update the 3D chair model to implement those changes
The authors demonstrate BlenderAlchemy's capabilities across a range of 3D editing tasks, from simple object modifications to more complex scene-level changes described in natural language. The results show that this vision-language approach can effectively bridge the gap between human intuition and 3D modeling, making 3D content creation more accessible.
## Critical Analysis
The BlenderAlchemy paper presents a compelling new way to interact with and edit 3D graphics using natural language. The core technical approach of combining computer vision and language models is well-grounded in recent AI research, as evidenced by the relevant citations.
That said, the authors acknowledge several limitations and areas for future work. For example, the current system is limited to making changes to existing 3D scenes, and cannot yet generate entirely new 3D content from scratch based on language input alone. There is also room to improve the robustness and accuracy of the vision-language understanding, which could lead to better translation of natural language instructions into 3D editing actions.
Additionally, while the paper demonstrates the system's capabilities on a range of 3D editing tasks, it would be valuable to see more real-world user testing and evaluation. Understanding how non-expert users engage with and benefit from BlenderAlchemy in practice could uncover further opportunities for improvement.
Overall, the BlenderAlchemy research represents an exciting step forward in democratizing 3D content creation. By bridging the gap between human language and 3D modeling, the system has the potential to empower a much wider audience to participate in 3D design and visual storytelling. Further advancements in this direction could have significant implications for fields like [interactive data visualization](https://aimodels.fyi/papers/arxiv/text-based-reasoning-about-vector-graphics), architecture, gaming, and more.
## Conclusion
The BlenderAlchemy system demonstrates how the integration of computer vision and language models can enable a new paradigm for 3D graphics editing. By allowing users to describe their desired changes in natural language, the system makes 3D content creation more accessible and intuitive, without requiring specialized technical skills.
While the current implementation has some limitations, the core vision-language approach presents a promising direction for the future of 3D modeling and design tools. As AI language and vision capabilities continue to advance, systems like BlenderAlchemy could fundamentally transform how people interact with and create digital 3D worlds, unlocking new creative possibilities across a wide range of applications.

1,840,621 | Data Ingestion in Snowflake with Google Cloud Storage - Part I | In this article we will go through the process to ingest data into Snowflake from Google Cloud... | 0 | 2024-05-03T18:26:11 | https://dev.to/rajdas2412/data-ingestion-in-snowflake-with-google-cloud-storage-part-i-1mip | snowflake, gcp, dataengineering, data | In this article we will go through the process to ingest data into Snowflake from Google Cloud Storage (GCS). Along the way we will understand the required concepts and tasks involved in a step by step manner.
You can refer to the official docs [here](https://docs.snowflake.com/en/user-guide/data-load-gcs-config).
**Assumptions**
- You have an active Google Cloud account with permissions to create IAM roles, GCS buckets, Pub/Sub topics.
- You have an active Snowflake account with permissions to create Database, Schema, Stage, Integration Objects and fire queries.
Data Source: [Open Data](https://open.canada.ca/en)
**Create a bucket in GCS** (GCP)
We create a bucket in GCS `snowflake_gcs-stage-bucket` and a folder `raw_csv` inside it to stage the files that we would load into Snowflake later.
For the steps described here, **ACCOUNTADMIN** user and **COMPUTE_WH** Warehouse were used in the Snowflake account.
**Create a Database** (Snowflake)
Here we are creating a database to hold the manufacturing details of various Breweries.
```
CREATE DATABASE manuf_db;
USE manuf_db;
```
**Create Storage Integration Object** (Snowflake)
A storage integration is a Snowflake object. It stores a generated identity and access management (IAM) entity for the external cloud storage location, in our case it will be Google Cloud Storage (GCS). The IAM entity will be provided with permissions to access the GCS location within the GCP Project.
In the below SQL, we are creating the storage integration object which will have access to two locations viz `snowflake_gcs-stage-bucket/` and `snowflake_gcs-stage-bucket/raw_csv/`. This object will enable us to create a staging location to host our files which are located externally i.e. outside of Snowflake.
```
CREATE STORAGE INTEGRATION snowflake_gcp_int
TYPE = EXTERNAL_STAGE
STORAGE_PROVIDER = 'GCS'
ENABLED = TRUE
STORAGE_ALLOWED_LOCATIONS = ('gcs://snowflake_gcs-stage-bucket/', 'gcs://snowflake_gcs-stage-bucket/raw_csv/');
```
In case you get the below error, make sure the `gcs:// ` url prefix is preceding the GCS bucket/folder location.
```
DESC STORAGE INTEGRATION snowflake_gcp_int;
```
Make a note of the `STORAGE_GCP_SERVICE_ACCOUNT` from the output above. This is a service account created by Snowflake which needs to be provided with appropriate permissions in Google Cloud so that it can access GCS.
You may notice that the nomenclature of the Service Account appears to be something within an AWS account rather than GCP. This is because my Snowflake account is hosted in AWS.
The `STORAGE_GCP_SERVICE_ACCOUNT` needs to be provided with the following permissions.
` storage.buckets.get
storage.objects.create
storage.objects.delete
storage.objects.get
storage.objects.list `
**Create an IAM Role** (GCP)
Create a Role in Google Cloud and add the required permissions. This step can be performed using GCP Web UI or CLI. The gcloud CLI command shown below creates a new role `snowflake_gcp_role` and adds the required permissions to it. Replace the **GCP-PROJECT-ID** with your own GCP Project ID in the below command.
```
gcloud iam roles create snowflake_gcp_role --project=GCP-PROJECT-ID
--description="This role will be assigned to Snowflake Account to enable GCS Access" --permissions=storage.buckets.get,storage.objects.create,storage.objects.delete,storage.objects.get,storage.objects.list
```
**Attach Principal and assign Role** (GCP)
In this step we will add the `STORAGE_GCP_SERVICE_ACCOUNT` to the GCS bucket and assign the Role to the account. In the GCP Web UI, go to Cloud Storage and open the GCS bucket we created for staging our files. Click on the Permissions tab.
Now click on Grant Access
Under Add Principals set the `STORAGE_GCP_SERVICE_ACCOUNT` name and under Role set newly created IAM Role in GCP.
**Create an external stage** (Snowflake)
Here we are creating an external stage in Snowflake which references data files stored in a location within GCS. We provide the `STORAGE_INTEGRATION` object name created earlier which has the required access permissions to the external GCS location.
```
CREATE SCHEMA stages;
CREATE STAGE manu_db.stages.snowflake_gcp_stage
URL = ('gcs://snowflake_gcs-stage-bucket/raw_csv/')
STORAGE_INTEGRATION = snowflake_gcp_int;
SHOW STAGES IN manuf_db.stages;
```
**List files from the external stage** (Snowflake)
The LIST command may return empty results if no files are loaded in the designated GSC bucket/folder.
```
LIST @manuf_db.stages.snowflake_gcp_stage;
```
The `LIST` command may throw up an error as below if the `STORAGE_GCP_SERVICE_ACCOUNT` was not provided with appropriate permissions on the GCS bucket/folder.
Once you load files in the GCS bucket/folder, you will see output similar to the below.
You may query the file in the external storage using the below SQL.
```
SELECT $1, $2, $3
FROM @manuf_db.stages.snowflake_gcp_stage/beer-manufacturers-microbrewers-brands.csv;
```
Notice that the Header row is showing up as part of content from the staged file. We need to skip the header to avoid this error. We can create and re-use a File Format object for this.
**Create a file format** (Snowflake)
A file format is a named object in Snowflake which holds information about a particular file format like CSV/JSON etc. and certain attributes associated with the format. This object comes handy to describe the files in the staged location while loading into Snowflake tables.
```
CREATE SCHEMA file_formats;
CREATE OR REPLACE FILE FORMAT manuf_db.file_formats.file_format_csv
TYPE = CSV
FIELD_DELIMITER = ','
SKIP_HEADER = 1
FIELD_OPTIONALLY_ENCLOSED_BY = '"';
SHOW FILE FORMATS IN manuf_db.file_formats;
```
**Create Table** (Snowflake)
A table is created in the `manuf_db`. The `public `schema is the default schema in Snowflake.
```
CREATE TABLE manuf_db.public.manuf_tbl(
manuf_type varchar(20),
manuf_name varchar(100),
manuf_brand varchar(100)
);
SELECT * FROM manuf_db.public.manuf_tbl;
```
**Loading data into Table** (Snowflake)
The COPY INTO command will load staged file, the data from the file `beer-manufacturers-microbrewers-brands.csv`, into the existing table `manuf_tbl` by referencing the stage location `snowflake_gcp_stage` created earlier. Multiple runs of the COPY INTO table **will not** duplicate the data unless `FORCE = TRUE` is specified as an optional clause.
```
COPY INTO manuf_db.public.manuf_tbl
FROM @manuf_db.stages.snowflake_gcp_stage
FILE_FORMAT = manuf_db.file_formats.file_format_csv
FILES = ('beer-manufacturers-microbrewers-brands.csv');
SELECT COUNT(*) FROM manuf_db.public.manuf_tbl;
```
These are all the Snowflake objects that we created in our account.
**Clean Up** (Snowflake)
Clean up by deleting the data from the table and also removing the staged file from GCS.
```
DELETE FROM manuf_db.public.manuf_tbl;
REMOVE @manuf_db.stages.snowflake_gcp_stage PATTERN='.*.csv';
```
In [Part-II](https://dev.to/rajdas2412/data-ingestion-in-snowflake-with-google-cloud-storage-part-ii-3l96) of Data Ingestion, we will use SnowPipe to auto-load data in Snowflake.

## **INTRODUCTION**
Like most people in the tech space that I have come across, my journey with tech or computers started as a kid.I had lots of interest in computers and I have carried that interest till this day.
## **FIRST IMPRESSIONS**
As someone who has built or worked with personal projects a lot, every time I see a new codebase the first thing that comes to mind is that "there’s a lot to learn". This is because there's always something newer or something simpler than how I would usually do it. In my first week, I felt overwhelmed by most of the tasks but after that I started to get hold of the standards or inputs that were required of me.
## **ON-BOARDING EXPERIENCE**
My onboarding experience was such a calm journey, my seniors and colleagues really made me feel at home and explained most of the things and standards to me. They also took me through the tools we use and all other stuff I would need to know. As an introvert I barely spoke or asked questions because i was shy but i'm gradually fitting in.
## **TECHNICAL CHALLENGES**
Even though I was abreast with OOP, I soon realised it wasn't the standard that I was required to have. I also realised my SQL skills would be put to a test because I only got my hands dirty with "ORMS". So far I have been putting in effort to quickly get the above skills so I can effectively contribute to my team
## **LEARNING CURVE**
So far the learning curve has been okay, this is because i'm quite knowledgeable with most of the technologies or frameworks we use here. I have also been passed some resources I could use to speed up my learning process
## **COLLABORATION AND TEAM DYNAMICS**
When I started, I was given the basic tasks to perform so as to build some "stamina". In the past weeks I have been given actual tasks that require research and lots of logic to build. I have also been allowed to take some decisions on how things should be and when the team didn't agree, I am made to understand why my decision or choice was not good enough.Interacting with my seniors has given me a specific line of thought to take when I try to tackle or solve problems
## **ACHIEVEMENTS**
No major achievements but I have been able to close all the tickets i have been assigned without making a mess of anything.
## **GROWTH**
I can say I have experienced some level of growth in several aspects. A few of them include my confidence , problem solving skills, time management and communication.
## **CONCLUSION**
So far I have enjoyed my experience at the workplace, the people, the benefits and the learning experience make me happy. Sometimes we may not even remember the simplest things and sometimes we write 100+ lines and everything works on the first run. Everyday isn't the same, we can only try our best and if things don't go well we try another day.

Undertaking Affiliations Nursing capstone projects base on the flawlessness of nursing undergrad arranging and bearing. For these exhaustive tasks, understudies [NURS FPX 4900 Assessment 2](https://onlinetutormasters.com/nurs-fpx-4900-assessment-2/) should organize their insight, limits, and encounters into a tremendous and persuading try. In any case, it can be difficult to deal with the complexities of a nursing capstone project, which is why many students turn to gifted relationships for assistance.
Nursing capstone projects go likely as a capstone experience for nursing understudies, permitting a reasonable chance to show their ability and status for gifted practice. These activities regularly coordinate all over appraisal, assessment, and execution of proof based intercessions to address guaranteed clinical thought inconveniences. As an enormous achievement in nursing preparing, the convincing zenith with respect to a capstone project is fundamental for understudies to graduate and enter the labor force.
A nursing capstone project ordinarily consolidates a couple of sections, including an issue demand, making study, plan, results, and conversation. Students should be able to identify a significant clinical problem, plan and execute a proof-based intervention, describe its outcomes, and lead a comprehensive analysis of the hypothesis. The undertaking ought to mirror the understudy's persuading thinking, clinical thinking, and expert judgment.
During the most striking method for managing completing their capstone project, nursing students persistently experience different blocks.

1,841,126 | Instant API for databases adds automatic TSID primary keys | In a previous post, we saw how we can read and write data through an instant API provided by DB2Rest.... | 0 | 2024-05-05T06:49:47 | https://dev.to/thadguidry/instant-api-for-databases-adds-automatic-primary-keys-5cpk | nocode, restapi, database, opensource | In a [previous post](https://dev.to/thadguidry/expose-your-database-as-a-rest-api-safely-and-without-code-5242), we saw how we can read and write data through an **instant API** provided by [DB2Rest](https://db2rest.com). It would be nice to have a way to automatically create chronological sequences of our written data so we do not have to code anything extra in our application when writing data out through our API.
## Benefits of TSIDs
[DB2Rest](https://db2rest.com) has a built-in ability to automatically create Time-Sorted Unique Identifiers ([TSID](https://www.wikidata.org/wiki/Q125756633)) that offer benefits such as the following:
* Chronologically sorted like integers.
* Compact storage (14 bytes).
* Efficient indexing due to sequential nature.
TSIDs combine the benefits of integers, UUIDs, and ULIDs and are a recommended alternative for primary key values. They borrow some structure from [Snowflake IDs](https://en.wikipedia.org/wiki/Snowflake_ID) and Instagram IDs.
One of the additional benefits are that we get automatic date timestamping that we can use for things like sorting and data analysis later on. This can save us from adding an additional Date column in our schema for our database tables. We get a timestamp, a node (shard) id, and a sequence number, all in one! TSIDs come in handy when writing data about [temporal entities](https://www.wikidata.org/wiki/Q26907166) or anything that is event-based, like comments, posts, transactions, etc. But they can also be used as a primary key for non-temporal data in your tables.
{% details Click for structure of TSID %}
* **42-bit timestamp**: Calculated using milliseconds from a reference date (e.g., 2020-01-01).
* **10-bit machine ID**: Unique identifier for the machine generating the TSID.
* **12-bit sequence number**: Ensures uniqueness within the same millisecond.
{% enddetails %}
When stored as a long TSIDs look like this:
`38352658567418872`
And when written as Text or a String they look like this:
`01226N0640J7Q`
## Auto Generating TSIDs
[DB2Rest](https://db2rest.com) can automatically generate TSID primary keys as it inserts data through its instant API into your database tables. It does this by auto detecting an existing primary key column in the table you are writing to and will use the datatype category (Integer-based or Text/String based) to generate the appropriate TSID format (Long/Number or Text).
Let's use a DB2Rest API endpoint to write to our `/actor/` table with bulk data and let DB2Rest worry about automatically creating our tables' primary keys for each row inserted.
**REQUEST:**
```curl
curl --request POST \
--url http://localhost:8080/actor/bulk \
--header 'Content-Type: application/json'
--data '[
{
"first_name" : "Salman",
"last_name" : "Khan"
},
{
"first_name" : "Hrithik",
"last_name" : "Roshan"
},
{
"first_name" : "Tom",
"last_name" : "Cruise"
}
]
```
**RESULT:**
Table: `actor`
| id | first_name | last_name |
| ------------- |:-------------:| ----------:|
| 0012 | John | Travolta |
| 0036 | George | Clooney |
| 01226N0640J7P | Salman | Khan |
| 01226N0640J7Q | Hrithik | Roshan |
| 01226N0640J7R | Tom | Cruise |
Notice that we had 2 existing rows in our `actor` table with id's `0012` and `0036` with famous actor names?
[DB2Rest](https://db2rest.com) detected the data type of our existing `id` column and determined to use the String format for automatic TSID generation when writing the 3 new rows of data from our API POST request. We didn't have to write any special application code ourselves to do this or even setup a database stored procedure!
## Summary
What's really amazing here is that DB2Rest automatically creates an API for our `actor` table (securely and safely) for fast frontend application development. We didn't have to code an API data access layer for our database tables at all! DB2Rest does this for us without using an ORM (Object Relational Mapper) or using any code generation that slows things down!
Read more about DB2Rest benefits in my previous post:
{% embed https://dev.to/thadguidry/expose-your-database-as-a-rest-api-safely-and-without-code-5242 %}
In summary, TSIDs strike a balance between integers and UUIDs, offering chronological sorting, compactness, and efficient indexing. If you plan to store UUID values in a primary key column, TSIDs are a recommended alternative.
You can **save 100's of hours of coding** data access layers by quickly enabling an **instant API** for your database by using [DB2Rest](https://db2rest.com) , an APACHE 2 licensed open source middleware. | thadguidry |

1,841,551 | Demystifying JavaScript Execution Context: A Beginner's Guide | JavaScript, the powerhouse of the web, holds a crucial concept at its core: Execution Context.... | 0 | 2024-05-17T05:40:17 | https://dev.to/jps27cse/demystifying-javascript-execution-context-a-beginners-guide-47i5 | javascript, webdev, programming, beginners | JavaScript, the powerhouse of the web, holds a crucial concept at its core: Execution Context. Understanding this concept is pivotal for any budding developer. In this comprehensive guide, we'll break down Execution Context in JavaScript, demystifying its intricacies with simple explanations and illustrative code examples.
### What is Execution Context?
Execution Context is like the environment in which JavaScript code is executed. Every time code runs in JavaScript, it runs inside an execution context. There are mainly three types of execution contexts in JavaScript:
1. **Global Execution Context**: This is the default context in which your JavaScript code runs. It's like the outermost layer, encompassing everything else.
2. **Function Execution Context**: Whenever a function is invoked, a new execution context is created for that function. This context includes the function's arguments, variables, and references to its outer lexical environment.
3. **Eval Execution Context** (Rarely used): When JavaScript code is executed using the `eval()` function, a new execution context is created for that code.
### Components of Execution Context
Each execution context consists of two essential components:
1. **Variable Environment**: This component contains all the variables declared within the context, along with their values. For global context, it includes global variables. For function context, it holds function arguments and local variables.
2. **Scope Chain**: This is a list of all the variable objects that the context has access to. It's crucial for JavaScript's lexical scoping, determining the accessibility of variables within nested functions.
### Code Examples
Let's dive into some code examples to solidify our understanding:
```javascript
// Global Execution Context
let globalVar = 'I am global';
function outerFunction() {
let outerVar = 'I am outer';
function innerFunction() {
let innerVar = 'I am inner';
console.log(innerVar); // Accessible
console.log(outerVar); // Accessible
console.log(globalVar); // Accessible
}
innerFunction();
}
outerFunction();
```
In this example, we have a global variable `globalVar` and two nested functions. Each function creates its own execution context with its variable environment and scope chain.
### Execution Context Stack
Execution contexts are organized in a stack-like structure called the **Execution Context Stack** or **Call Stack**. When a function is invoked, a new execution context is created and pushed onto the stack. When the function finishes executing, its context is popped off the stack.
### Conclusion
Understanding Execution Context is fundamental to mastering JavaScript. It governs how variables are scoped, accessed, and managed during code execution. By grasping its concepts and mechanics, you'll be equipped to write more robust and efficient JavaScript code.
In this guide, we've covered the basics of Execution Context, its components, and provided illustrative code examples. Keep exploring, experimenting, and practicing to deepen your understanding of this crucial JavaScript concept. Happy coding!

1,841,575 | Scalable network reconstruction in subquadratic time | Scalable network reconstruction in subquadratic time | 0 | 2024-05-03T13:00:58 | https://aimodels.fyi/papers/arxiv/scalable-network-reconstruction-subquadratic-time | machinelearning, ai, beginners, datascience | *This is a Plain English Papers summary of a research paper called [Scalable network reconstruction in subquadratic time](https://aimodels.fyi/papers/arxiv/scalable-network-reconstruction-subquadratic-time). If you like these kinds of analysis, you should subscribe to the [AImodels.fyi newsletter](https://aimodels.substack.com) or follow me on [Twitter](https://twitter.com/mikeyoung44).*
## Overview
- This paper presents a scalable algorithm for reconstructing large-scale networks in subquadratic time.
- The authors introduce a novel technique that leverages a combination of coordinate descent and randomized sketching to significantly improve the computational efficiency of network reconstruction.
- The proposed approach outperforms existing methods in terms of both running time and reconstruction accuracy, making it a promising solution for analyzing complex real-world networks.
## Plain English Explanation
In this research, the authors have developed a new way to reconstruct large networks, such as social networks or biological networks, in a much faster and more efficient manner. The traditional methods for reconstructing these networks can be very slow, especially as the networks get larger and more complex.
The key insight behind the authors' approach is to use a technique called "coordinate descent" in combination with "randomized sketching." [Coordinate descent](https://aimodels.fyi/papers/arxiv/decentralized-online-regularized-learning-over-random-time) is a mathematical optimization algorithm that can break down a complex problem into smaller, more manageable pieces. [Randomized sketching](https://aimodels.fyi/papers/arxiv/one-dimensional-tensor-network-recovery) is a way of summarizing large datasets using random sampling, which can significantly reduce the computational burden.
By using these two techniques together, the authors are able to reconstruct large networks much faster than traditional methods, without sacrificing the accuracy of the reconstruction. This is particularly important for analyzing complex real-world networks, such as social media [networks](https://aimodels.fyi/papers/arxiv/sifting-out-communities-large-sparse-networks) or biological [systems](https://aimodels.fyi/papers/arxiv/rate-analysis-coupled-distributed-stochastic-approximation-misspecified), where the ability to quickly and accurately reconstruct the underlying network structure is crucial for gaining insights and making informed decisions.
## Technical Explanation
The authors propose a novel algorithm for scalable network reconstruction that leverages a combination of coordinate descent (CD) and randomized sketching. The CD baseline is used to iteratively update the network structure by optimizing the objective function with respect to one node at a time.
To achieve subquadratic time complexity, the authors introduce a randomized sketching technique that compresses the input data matrix, reducing the computational burden of the CD updates. Specifically, they construct a randomized linear map that projects the input matrix onto a lower-dimensional space, allowing the CD updates to be performed efficiently on the compressed representation.
The authors provide theoretical analysis to show that their proposed algorithm can achieve a time complexity of O(n log n), where n is the number of nodes in the network, compared to the quadratic time complexity of the baseline CD method. They also demonstrate through extensive experiments that the subquadratic algorithm outperforms the CD baseline in terms of both running time and reconstruction accuracy across a variety of synthetic and real-world network datasets.
## Critical Analysis
One potential limitation of the proposed approach is that it relies on the assumption that the network structure can be well-approximated by a low-rank representation. While this assumption may hold for many real-world networks, there could be cases where the network structure is more complex and cannot be effectively captured by the low-rank sketching technique.
Additionally, the authors only consider the case of undirected networks in this work. Extending the subquadratic reconstruction algorithm to handle directed networks or more general graph structures could be an interesting direction for future research.
It would also be valuable to explore the performance of the proposed method in the presence of noisy or incomplete data, which is often the case in real-world network reconstruction scenarios. The robustness of the algorithm to such challenges could be an important factor in its practical applicability.
## Conclusion
The authors have presented a highly scalable algorithm for reconstructing large-scale networks in subquadratic time. By combining coordinate descent and randomized sketching techniques, their approach significantly improves the computational efficiency of network reconstruction compared to existing methods.
The ability to quickly and accurately reconstruct complex network structures has important implications for a wide range of applications, from social network analysis to biological systems modeling. The proposed algorithm represents a significant advancement in this field and could pave the way for more efficient and insightful network-based studies in the future.

tags: blogging,javascript,node,astro
canonical_url: https://billyle.dev/posts/use-husky-and-node-to-unstage-draft-posts-from-git
---
Astro allows us to only create static files during the build step for published work by filtering through the collection and filtering out draft posts. But it doesn't prevent Git from knowing the context of your collection.
So what ends up happening is you might check in your drafts in your Git history. For me, I didn't want my draft blog posts to be viewable until they were ready to be published.
I thought about adding my draft files into another folder and using gitignore, but it wasn't an elegant solution since I have to manually move files from the drafts folder and into the proper folder each time I want to publish a blog.
A solution I came up with was to use Husky to trigger pre-commit scripts and unstaged all my markdown drafts. I'll show you exactly how I did that below.
## What is Husky?
If you don't know what Husky is, it's a program that will run during different life cycles of your Git workflow. This is particularly useful for doing a bunch of things before and after committing files in your Git history.
Usually, you will see the `pre-commit` hook often used for performing linting, prettifying, or running tests on your project.
### List of Git Hooks Husky supports
Husky supports all client-side Git hooks. There are 13 of them in total.
- applypatch-msg
- commit-msg
- post-applypatch
- post-checkout
- post-commit
- post-merge
- post-rewrite
- pre-applypatch
- pre-auto-gc
- pre-commit
- pre-push
- pre-rebase
- prepare-commit-msg
If you're interested in what Git hooks are, here is a list of all the different [Git hooks](https://git-scm.com/docs/githooks).
## Install Husky
To [install Husky](https://typicode.github.io/husky/), you need to have `Node` installed since you will use `npm`.
I use `pnpm`, but you can use any package manager supported in the link above.
Run the command `pnpm add husky -D`. This will install Husky as a devDependency.
Then run `pnpm exec husky init`, so Husky can take care of the setup for you.
If you look in your project now, you should see a `.husky` folder. If you look inside, you will see a `pre-commit` file with the command `pnpm test` inside.
As a concept, if you tried to run `git add .` and `git commit -m "my message"` the pre-commit hook will trigger and run `pnpm test`. If your test happens to fail, then it won't commit anything and your Git history remains untouched otherwise you're golden.
## Retrieving a list of your staged files
Now we need a way to list out all the files that are staged in Git. Luckily for us, we can do that with this command, `git diff --name-status --staged`.
This command grabs all staged files that were changed and returns the status mode and file names. This is how it would look in your terminal:
Press <kbd>q</kbd> to kill the process.
## Preparing the Node script
Our next step requires us to write a Node script. Since my project is written in Typescript and I want to take advantage of the type system, so I am using `ts-node` to run the script.
However, if you're just using Node, then you can change the file extension to `.js`, and remove the types, and it should work the same.
### Prerequisites
- Install `front-matter` and `ts-node` packages
- Ensure you have a Post schema type
We need a way to read from our front matter in our `.md` files. I found this package, [front-matter](https://www.npmjs.com/package/front-matter), that easily allows us to get key-value pairs of our markdown.
### The meat of the script
I created a file in my root directory called `unstage-drafts.ts`.
We'll need to change who can access the file with `chmod`, so in your terminal run the command `chmod 777 unstage-drafts.ts` to change the permissions.
Then inside the file, I wrote this script:
```
import fs from "node:fs/promises";
import childProcess from "node:child_process";
import util from "node:util";
import fm from "front-matter";
import type { Post } from "src/content/config.ts";
const execPromise = util.promisify(childProcess.exec);
let data = "";
process.stdin.on("readable", () => {
let chunk;
while (null !== (chunk = process.stdin.read())) {
data += chunk;
}
});
process.stdin.on("end", async () => {

draftCount++;
await execPromise(`git reset ${file}`);
}
}
if (draftCount === markdownFiles.length && !stagedFiles.length) {
throw Error("only draft posts were staged.");
}
});
```
### Script breakdown
Let's do a quick break of what's going on.
The necessary imports of modules I'm using:
```
import fs from "node:fs/promises";
import childProcess from "node:child_process";
import util from "node:util";
import fm from "front-matter";
import type { Post } from "src/content/config.ts";
```
The command `git diff --name-status --staged` writes to out `stdout`, so we can read from it in Node by using `process.stdin`.
Here we're listening to the event "readable" which is a stream of bytes. Then each chunk is appended in our `data` variable.
```
let data = "";
process.stdin.on("readable", () => {
let chunk;
while (null !== (chunk = process.stdin.read())) {
data += chunk;
}
});
```
We're going to `promisify()` our `childProcess.exec`, so we can await it later.
```
const execPromise = util.promisify(childProcess.exec);
```
When our readable stream ends, we will listen to the event `end` and run an async callback function that uses the `data` variable to process all the staged files.
```
process.stdin.on("end", async () => {});
```
I have two variables - one that will keep track of non-`.md` files and another to store markdown files, respectfully called `stagedFiles` and `markdownFiles`.
I split the data by new lines and then filtered valid entries. Then for each item in the array, I test some conditions to check whether the file is `.md` or not.
If it is a markdown file, we want to check if it's not a `D` status. The "D" status here means that I've untracked the file that was previously tracked by Git and I don't want to unstage those changes.
If it is not "D" then we push it to the `markdownFiles`.
```
const stagedFiles: string[] = [];
const markdownFiles: string[] = [];
data
.split("\n")
.filter((x) => x)
.forEach((line) => {
if (line.endsWith(".md")) {
if (!line.startsWith("D")) {
const markdownFile = line.split("\t")[1] as string;
markdownFiles.push(markdownFile);
}
} else {
stagedFiles.push(line);
}
});
```
After we have a list of our staged markdown files, we're going to process each file in a for loop and read from the front matter. If the post is a draft, we update a counter and call `await execPromise()` to unstage it.
```
let draftCount = 0;
for (const file of markdownFiles) {
const content = await fs
.readFile(file, { encoding: "utf-8" })
.then((f) => fm<Post>(f));
if (content.attributes.draft) {
draftCount++;
await execPromise(`git reset ${file}`);
}
}
```
This next condition is a guard to check if there are staged files to commit while also checking if all staged markdown files were drafts. If this ends up being true, it must mean we probably did a `git commit` on staged files that were only markdown drafts. I threw an error so that there isn't an empty commit history if this does happen.
```
if (draftCount === markdownFiles.length && !stagedFiles.length) {
throw Error("only draft posts were staged.");
}
```
That's the entirety of the script. As you can see, you can do a lot more in this script if there are extra requirements.
## Piping it all together
Back in our `.husky/pre-commit` file where we had a single line of `pnpm test`, we're going to replace that by combining both the `git diff` and the Node script by using the piping method.
Replace `pnpm test` with `git diff --name-status --staged | node --import 'data:text/javascript,import { register } from "node:module"; import { pathToFileURL } from "node:url"; register("ts-node/esm", pathToFileURL("./"));' unstage-drafts.ts`
The verboseness of the command above is important to Typescript and Node.
If you're not using Typescript, it will look a lot simpler:`git diff --name-status --staged | node unstage-drafts.ts`
## Untracked files committed to history
There's one other important thing that I want to do -- removing my existing drafts in my Git history, so they are no longer available in my public repo.
To do that, run the command `git rm --cached <path/to/file>`.
I have one file, `learning-golang-for-javascript-developers.md`, that is a draft and is already in my Git history. I want to remove it so I run `git rm --cached src/content/posts/learning-golang-for-javascript-developers.md`.
Now the file is labeled as Untracked by Git.
## Seeing the pre-commit hook in action
Time to put it to the test and make sure our drafts are no longer being committed. Running the commands in order to make sure I have everything staged correctly.
1. `git add .`
2. `git rm --cached src/content/posts/learning-golang-for-javascript-developers.md`
3. then followed by `git status`.
This is the output:
```
➜ billyle.dev git:(ft/husky-precommit) ✗ git status
On branch ft/husky-precommit
Changes to be committed:
(use "git restore --staged <file>..." to unstage)
modified: .astro/types.d.ts
new file: .husky/pre-commit
modified: package.json
modified: pnpm-lock.yaml
new file: public/images/blog/husky-node-unstage/husky-post-setup.png
new file: public/images/blog/husky-node-unstage/list-staged-files.png
new file: public/images/blog/husky-node-unstage/pre-commit-piping-script.png
new file: public/images/blog/husky-node-unstage/untrack-files.png
modified: src/content/config.ts
deleted: src/content/posts/learning-golang-for-javascript-developers.md
new file: src/content/posts/use-husky-and-node-to-unstage-draft-posts-from-git.md
modified: src/layouts/BlogLayout.astro
new file: unstage-drafts.ts
Untracked files:
(use "git add <file>..." to include in what will be committed)
src/content/posts/learning-golang-for-javascript-developers.md
```
Now I will make a `git commit -m "remove existing drafts from git history and unstage drafts"` and see that this blog post is removed from the staging area.
Checking `git status` shows me:
```
➜ billyle.dev git:(ft/husky-precommit) ✗ git status
On branch ft/husky-precommit
Untracked files:
(use "git add <file>..." to include in what will be committed)
src/content/posts/learning-golang-for-javascript-developers.md
src/content/posts/use-husky-and-node-to-unstage-draft-posts-from-git.md
```
Awesome! It worked! I can freely work on all my draft blog posts without ever checking them into Git again.
## The takeaway
So if you're like me and want some bit of automation in your creative process, you can use this solution. I'm pretty sure there are better ones out there but if you like this approach, feel free to take it and use it as your own.
In summary, we learned how to use Husky, piping the `git diff --name-status --staged` command output into Node, and letting our script unstaged draft blog posts.
I hope you learned something today and if not, that's alright! I'm glad you took the time to read it anyway.
Well, until next time, happy coding! | billyle |
1,841,618 | How to Toggle Between Dark and Light Themes with Tailwind in React/NextJS application | As a web developer, you may want to offer your users the option to switch between dark and light... | 0 | 2024-05-03T13:21:13 | https://dev.to/shawon/how-to-toggle-between-dark-and-light-themes-with-tailwind-in-reactnextjs-application-2317 | react, nextjs, tailwindcss, webdev |
As a web developer, you may want to offer your users the option to switch between dark and light themes in your application. This can enhance the user experience by allowing them to choose the theme that best suits their preferences or environment. In this blog post, we'll explore how you can implement a theme toggle switch using React and Tailwind CSS.
## Setting Up the Project
First, let's assume you have a basic React project set up with Tailwind CSS configured. In your Tailwind configuration file (`tailwind.config.js`), you'll need to enable dark mode:
```
module.exports = {
darkMode: "class",
// rest of the config
};
```
By setting `darkMode` to `"class"`, Tailwind CSS will generate dark mode variants based on the presence of a `dark` class on the `html` element.
## Creating the Toggle Switch Component
Next, let's create a `ThemeToggleSwitch` component that will allow users to toggle between dark and light themes. Here's an example implementation:
```
import React, { useState, useEffect } from "react";
const ThemeToggleSwitch = () => {
const [isChecked, setIsChecked] = useState(false);
useEffect(() => {
const htmlElement = document.documentElement;
if (isChecked) {
htmlElement.classList.add("dark");
} else {
htmlElement.classList.remove("dark");
}
}, [isChecked]);
const handleToggle = () => {
setIsChecked(!isChecked);
};
return (
<div>
<label className="switch">
<input id="toggle" type="checkbox" checked={isChecked} onChange={handleToggle} />
<span className="slider"></span>
</label>
<div className="slide-block"></div>
{/* Add your custom styles here */}
</div>
);
};
export default ThemeToggleSwitch;
```
In this component, we use the `useState` hook to manage the state of the toggle switch (`isChecked`). The `useEffect` hook is responsible for adding or removing the `dark` class on the `html` element based on the value of `isChecked`.
When the user toggles the switch, the `handleToggle` function is called, which updates the `isChecked` state. This triggers the `useEffect` hook to update the `dark` class on the `html` element accordingly.
## Integrating the Toggle Switch
To use the `ThemeToggleSwitch` component in your application, simply import it and render it wherever you want the toggle switch to appear. For example, you can include it in your navigation bar or settings menu.
```
import ThemeToggleSwitch from "./ThemeToggleSwitch";
const App = () => {
return (
<div>
{/* Your app content */}
<ThemeToggleSwitch />
</div>
);
};
export default App;
```
## Styling the Toggle Switch
You can customize the appearance of the toggle switch by adding your own styles. In the provided code snippet, you can see an example of CSS styles that define the colors and transition effects for the toggle switch.
Feel free to modify the styles to match your application's design and branding.
## Conclusion
By following these steps, you can easily implement a theme toggle switch in your React application using Tailwind CSS. This allows your users to switch between dark and light themes seamlessly, providing them with a personalized and enjoyable experience.
Remember to test your toggle switch thoroughly to ensure it works as expected and provides a smooth transition between themes.

I find lots of... | 0 | 2024-05-03T14:10:56 | https://dev.to/buditanrim/for-2-years-ive-been-collecting-productivity-tips-you-might-find-it-useful-4hjo | productivity | Since last year, I've been reading a lot of discussions about Productivity and ADHD. I find lots of valuable tips and have been compiling them on my Obsidian note. I have tried some of them, and I want to share these with y'all:
## Increase focus (combat distractions)
* Disable all your notifications, except for essential apps
* I find taking less sugar or carbohydrates during lunch helps a lot! Less sleepy!
* Set clear expectations and targets with your team or supervisor
* Exercise in the morning or walk. Your brain will focus better after some exercise.
* Listen to brown or white noise or any music without lyrics to your liking. My favorite so far is YouTube music, and I usually find one-hour lo-fi or instrumental music.
* Consider a site blocker if you find yourself opening a certain website
* Keep your to-do list at eye level. I use sticky notes, and recently, I used an app called Today, which has floating notes that stick on top.
* Brain dump all tasks quickly in the morning, then choose 1-2 critical tasks to focus on.
## Deal with mood swings
* Remind yourself that the world won't end if a few things fall behind.
* Ignore the awkward thing you did last week. People won't remember it.
* Brain dump in a notebook by your bed every night. It helps you to calm down and think.
* If you felt unproductive yesterday, don't hate yourself. Focus on improving yourself in the present.
* I use Obsidian to write daily journals
## Get things done
* Put your todo in a place you can always see.
* Break down tasks into smaller chunks until they feel manageable
* Use Pomodoro. If 25 minutes work, a 5-minute break doesn't work, try 50 minutes work, a 10-minute break.
* Sometimes, I like to use a timer instead of Pomodoro. I like to use Toggl to track my time.
* Put your phone out of sight (in a different room)
* When you take breaks, make sure they aren't too interesting. Otherwise, you will get absorbed in them. Just go to the bathroom or clean during your break.
* Time block your calendar so you know what your day looks like. But don't beat yourself up if it doesn't go as planned. ⭐️ My favorite app for this is Today (usetoday.app). I can see tasks and calendars side by side.
* Download an app that chimes every hour so you get a sense when the time has passed
## For daily things
* Three-point check before you go out: Phone, wallet, keys
* Have one bag for all your essentials—keys, chargers, toothbrushes—and when you go out, just grab that bag. Easy peasy!
* Put a bowl near your door for your keys, badges, or wallet so you can't leave without ALL the stuff you need. My spouse finds this helpful!
* Listen to podcasts when doing chores. It gives me excitement.
## For traveling
* Pack things weeks before so you don't forget
* Have a checklist (toiletry, passport, what to check before leaving the house)
* Write things down if you worry about "Do I need a visa?" then write it in a FAQ format. Question: "Do I need a Visa to South Korea?" Answer: "*No. Here's the link from the official website."* I like to use Notion for every trip.
* Find friends who is detail-oriented to plan the itinerary, ideally they know your condition.
* Set two alarms: (2 hours) and (30 mins) before the time you should go to the airport. | buditanrim |

Welcome to my... | 27,127 | 2024-05-03T16:23:05 | https://jaydevm.hashnode.dev/nextjs-essentials-part-1-introduction | nextjs, fullstack, javascript, typescript | _This post was originally published on my [blog](https://jaydevm.hashnode.dev/)._
## **What is this guide?**
Welcome to my comprehensive guide on Next.js! In this guide, I aim to introduce you to the powerful features of Next.js, a framework that enhances the capabilities of React to deliver richer web experiences. Whether you're just starting out or looking to level up your web development skills, this guide is designed to walk you through the essentials of using Next.js effectively. I'll break down complex concepts into manageable parts, provide practical examples, and share tips to help you master this tool. By the end of this series, not only will you understand why Next.js is so useful, you’ll also be equipped to start building your own projects with confidence.
## What is Next.js?
Next.js is a popular and versatile full-stack JavaScript / TypeScript framework for creating static sites, APIs, and interactive web browser applications. Launched by Vercel in 2016, it builds on React, providing a more integrated solution to web development challenges.
If you’re new to these concepts, don’t worry — we’ll break them down further as we go.
Next.js has grown significantly since its initial version. Since then, it has benefited from thousands of man hours dedicated its development and has been downloaded by developers millions of times.
The reason it’s so popular is obvious to its many users: the framework does a lot of the heavy lifting for you. Everything from backend routing to frontend components have pre-built patterns in Next.js to help you ship faster!
## Why would you use it?
As I alluded to above, there are many features to love about Next.js. Here are a few of the highlights:
1. **Seamless page routing**: the way you organize your files automatically becomes your app’s URL structure. For example, `app/about.js` translates to [`yourwebsite.com/about`](http://yourwebsite.com/about) , greatly reducing the amount of boilerplate you need to write.
2. **API routing**: the same file-based routing pattern applies to the backend too, allowing you to easily create API endpoints.
3. **Enhanced perfomance**: you get code splitting, image optimization, and static file caching for free through `next build`.
4. **Built-in CSS support**: no matter what CSS framework you prefer, be it CSS modules, utility frameworks like Tailwind, or CSS-in-JS, Next.js has an integration for it.
5. **Flexible data fetching**: with support for both server-side and client-side rendering, you can really tune your app’s performance.
## Reasons not to use Next.js
While there are many reasons to use Next.js, there is no tool that’s appropriate for every situation. This framework’s opinionated nature is a boon to certain use cases but a dealbreaker for others. Let’s talk about when you might want to consider other technology choices:
1. **Steep learning curve**: Power comes with a price. Next.js introduces additional abstraction and configuration on top of React and modern full-stack patterns. If you’re a new developer, you may want to start by learning React first!
2. **Less flexibility**: Next.js may be overkill for very simple, static websites, or client-side apps that don’t require much optimization. In those cases, you might not require server-side rendering or built-in API routes. Simpler static site generators or a separate frontend and backend might be more efficient.
3. **Coupled to React**: Next.js is specifically built for React. If you or your team has preference for Vue, Angular, or another framework, you might want to go a different route from Next.
4. **API flexibility**: Although Next.js supports API routes, if your backend needs are complex, involving heavy microservices architectures or serving a wide range of clients beyond web applications, considering a more tailored backend solution might be beneficial.
## Next steps
Excited about what Next.js offers? Let’s continue to [part 2](https://dev.to/jaydevm/a-quick-guide-to-nextjs-setup-4jlg) of the guide, where we will dive into setting up your first Next.js project, discussing different configurations, and how to start building right away.

1,841,903 | Your containerized application with IAC on AWS — Pt.2 | Hi everyone! We’ll see how to create our terraform modules in this blog article. Next, we’ll publish... | 27,490 | 2024-05-03T18:08:48 | https://medium.com/@shescloud_/your-containerized-application-with-iac-on-aws-pt-2-8430f710a516 | Hi everyone! We’ll see how to create our terraform modules in this blog article. Next, we’ll publish our application to AWS Fargate using the terraform modules we created here and also terragrunt.
**TERRAFORM**
We will establish our directory structure and our terraform module scripts in this blog article. We will set everything up and utilize terraform in conjunction with Terragrunt in part 3.
**DIRECTORIES**
Our codes must be organized at the directory level in order to use terraform and terragrunt:
```
app
modules
├── amazon_vpc
├── aws_loadbalancer
├── aws_fargate
├── aws_roles
├── aws_ecs_cluster
└── aws_targetgroup
└── aws_certificate_manager
```
```
terragrunt
└── dev
└── us-east-1
├── aws_ecs
│ ├── cluster
│ └── service
├── aws_loadbalancer
├── amazon_vpc
├── aws_targetgroup
├── aws_roles
├── aws_certificate_manager
└── terragrunt.hcl
```
- **app**: This is our infrastructure’s primary directory.
- **modules**: Each unique AWS resource or service has a subdirectory within this directory. The modules will be inserted here, arranged according to resources like VPC, load balancers, ECS, etc.
- **Terraform** **subdirectories**: Module-specific Terraform files are located in subdirectories like amazon_vpc and aws_loadbalancer.
- **Terragrunt**: Terragrunt configurations are kept in this directory.
- **dev**: Stands for the configuration of the development environment.
- **us-east-1**: Configurations unique to the AWS region “us-east-1”.
- **Terragrunt subdirectories**: Environment- and region-specific options for individual services may be found in the aws_ecs, aws_loadbalancer, amazon_vpc, etc. folders.
- **terragrunt.hcl**: This is our Terragrunt configuration file, where we will include backend configurations as well as those that apply to all services in the “us-east-1” area of the development environment.
-** Modules have three files**: variables.tf, main.tf, and _outputs.tf in each of the subdirectories. Roles will make use of a _data.tf
- **main.tf**: The main.tf file, which defines and configures AWS resources, is the hub of the module.
- **variables.tf**: Allows for module customisation and reuse by defining variables that the module will use.
- **_outputs.tf**: Indicates which module outputs — information — will be accessible to other modules or the Terraform project in its whole.
- **_data.tf**: To consult and look up information on already-existing resources or services, we shall utilize data.
**RESOURCES**
The following are the AWS resources that we will use:
- VPC
- SUBNETS
- ROUTE TABLE
- INTERNET GATEWAY
- NAT GATEWAY
- ELASTIC IP
- ECR
- SECURITY GROUP
- APPLICATION LOAD BALANCER
- FARGATE
- ROUTE53
- ACM
- TERRAFORM MODULES
**VPC**
Let’s get started with VPC module creation. It will be necessary for each and every one of our apps’ network connections.

In today's digital world, **block ciphers** are fundamental to online encryption. They handle most of the encryption on the internet, securing our communications and data. In this blog post, we'll explore the key aspects of block ciphers, delve into its popular **modes of operation**, as well as take a closer look at the Advanced Encryption Standard (AES).
## What Are Block Ciphers?
Block ciphers are the workhorse of encryption on the internet today. They handle the bulk of the encryption that is done over the internet. Block ciphers encrypt a fixed-length chunk of bits called a block where each block is encrypted separately.
Block ciphers are made up of a family of three functions and are specified as follows:
1. A **keygen** function that accepts a security parameter 𝑘 and outputs a random 𝑘-bit key:
𝑘→{0,1}𝑘
2. An **encryption** that accepts a 𝑏-bit plaintext and 𝑘-bit key and outputs a 𝑏-bit ciphertext:
{0,1}𝑏×{0,1}𝑘→{0,1}𝑏
3. A **decryption** that accepts a 𝑏-bit ciphertext and 𝑘-bit key and outputs a 𝑏-bit plaintext:
{0,1}𝑏×{0,1}𝑘→{0,1}𝑏
An important parameter in block ciphers is the block length 𝑏. It determines how large of chunks the overall ciphertext and plaintext will be parsed into.
An ideal block cipher requires the encryption to be **injective and surjective (bijective)**. This means that each plaintext maps to a **unique ciphertext** and each ciphertext maps to a **unique plaintext**. This creates an encryption method that essentially just creates a permutation (shuffle) of 𝑏-bit strings.
If we have a 𝑏-bit block, there is **2𝑏** possible input plaintext messages and **2𝑏** possible output ciphertext messages. There are also **2𝑏!** Permutations of **2𝑏** elements. If the key used is **𝑘-bits**, then there are **2𝑘** possible key values, and each key “chooses” some permutation from the permutation space. **2𝑘** is often much smaller than **2𝑏!** So there’s usually a large number of permutations that aren’t possible for a cipher.
*A block cipher can be thought of as a large collection of codebooks. A codebook is a book with a list of plaintext elements on one side and a list of associated ciphertext elements on the other. The key is simply used to choose which book to use.*
## Modes of Operation
A modern block cipher typically encrypts 16 bits at a time, so to encrypt a large plaintext, it must first be **parsed into smaller blocks**. The mode of operation defines the method used to combine a block cipher and encrypt a large block of data.
### Electronic Codebook Mode (ECB)
The simplest mode of operation is the electronic codebook mode (ECB). It takes the plaintext, divides it into individual 𝑏-bit blocks, and encrypts each one separately using the same key.
A 16-bit data block using an 8-bit block cipher will first be divided into 2 blocks, encrypted, each with the same key, and then recombined to create a 16-bit ciphertext.
If using a block size of 128 bits, then the codebook would have 2128 entries and be so large that you could never write it down on paper.
A limitation of this mode of operation is that on a long block of repeated data, patterns will start to emerge, revealing information about both the key and the plaintext. This mode of operation is not secure under eavesdropping (IND-EAV).
### Cipher Block Chaining (CBC)
The idea of cipher block chaining (CBC) mode is to exclusive or (XOR) the plaintext of every block with the ciphertext of the previous block. This combined value is the data that is then put into the encryption function.
Using this mode of operation, even large blocks of structured data lose their structure due to the feed-forward nature of the encryption mode.
Since the first block of plaintext has no previous block of ciphertext to use, an initialization vector (IV) is used to get things going.
Due to the symmetry of the XOR operation, when decrypting, you can follow the same path as encryption, just in reverse. Note that only the vertical arrows reverse direction in the diagrams to the left, as the previous ciphertext block is still used to decrypt the plaintext following it.
An essential property of the mode of operation is that it easily allows for randomized encryption. Different IVs produce different ciphertexts on the same plaintext, and this property can be used to protect the encryption method from chosen plaintext attacks.
Note that the IV is not a secret, is sent along with the ciphertext, can only be used once, and must not be predictable.
### Counter Mode (CTR)
Counter mode (CTR) is different from **CBC mode** as you never actually put the plaintext through the encryption function. Instead, you encrypt a counter, and **XOR** the result with the plaintext.
When encrypting using CTR mode, the first IV is decided upon, and then the subsequent IVs simply increment by 1. So, in an example where the IV is 2 bits, the first block might be 00, the next 01, and so on….
Decryption is the exact same as encryption, on the inputs to the XOR function are reversed. Notice that decryption involves the encryption method of the block cipher.
This model is not vulnerable to padding oracle attacks, has a simple implementation, and the computation is parallelizable, pre-processable, and random access. However, this mode is not safe for small block lengths (<128-bits).
## Advanced Encryption Standard (AES)
Advanced encryption standard (AES) is the most commonly used block cipher on the internet today. At a high level, the AES cipher uses a 128-bit block. This means it takes 128 bits of plaintext and produces 128 bits of ciphertext. The key can either be 128-bits, 192-bits, or 256-bits. The plaintext is combined with the key through multiple passes of a round.
Each stage has identical rounds. The key is changed at every round using a key schedule, which creates different sub-keys for each round.
AES uses 2 types of operations:
1. Operations that act on bytes (8-bits)
2. Operations that act on bits
The first operation is called **SubBytes** and is a bytewise substitution. A byte has 256 substitution possibilities so the substition lookup table (s-box) has 256 entries. There are 256! potential s-boxes that can be created, but instead of choosing a random permutation, AES designers chose an algebraic relationship. The output byte is the algebraic inverse of the input byte in what’s called a **galwa field**, and for good measure a constant value is added.
**S-boxes** are designed to be highly non-linear. The idea is that a small change in the input to induce a large change in the output.
The next step in AES is called **shiftRows** where all 16-bytes are arranged as a 4x4 square and a circular shift is applied. The top row is unchanged, the second row is shifted by 1 byte, the third row is shifted by 2 bytes, and the final row is shifted by 3 bytes.
The third operation is called **MixColumns** and applies galwa field arithmetic again, but this time using matrix multiplication. Instead of applying the changes to the rows, they’re applied to the columns. This is designed to create a property called diffusion. The goal is for the variables that appear in the equation to spread out.
In the last step, called **AddRoundKey**, the round-specific sub-key is XORed with all bits from the previous step. The output of the process is fed into the input of the next round, and the process continues.
For most people, AES can be treated like a black box. What matters most is not how it works but that a random secret key is generated when using it, the mode of operation is safe and randomized, and the initialization vector is unpredictable.
Overall, Block ciphers are vital for internet security, underpinning our communications and data protection. With various modes of operation, such as ECB, CBC, and CTR, and the robust AES algorithm, we have powerful tools to secure information. It's crucial to understand these encryption methods, as they are key to maintaining privacy and security in the digital age. | markyu |

It covers most of the basic priciples of React in one single project. It also includes a handful of challenges at the end to help you expand on what you've learned. I distinctly remember not being able to do any of them and quitting immediately. Well who's laughing now? (Me)
Anyway, we do it because it's there. Keep reading and I guarantee you'll find something you disagree with.
## 1. Change button to text
> For the current move only, show “You are at move #…” instead of a button.
[Full Solution on Codesandbox](https://codesandbox.io/p/sandbox/1-change-message-6j7qcv)
Nice easy one to start. The final button in the list does nothing so we replace it with a plain text message.
This is simple enough to do with a ternary inside the component. We already map each move to a list item `<li>`. Now inside each list item we check to see if it's the final element (remember -1 because zero index). Then we return either a string or a button.
```javascript
<li key={move}>
{move === history.length - 1 ? (
`You are at move #${move}`
) : (
<button onClick={() => jumpTo(move)}>{description}</button>
)}
</li>
```
## 2. Refactor Board
> Rewrite Board to use two loops to make the squares instead of hardcoding them.
[Full Solution on Codesandbox](https://codesandbox.io/p/sandbox/2-refactor-board-zkrpwj)
This is purely a refactor. Only the code will change. The actual rendered app and functionality will remain exactly the same.
First we'll try the nice solution. The one that I want to work. I want it to work so bad!
```javascript
const boardLayout = [...Array(9).keys()].map((i) => (
<Square value={squares[i]} onSquareClick={() => handleClick(i)} />
));
```
Look how neat that is! They key bit here is `[...Array(9).keys()]`. This is a time-honoured javascript hack that acts as our equivalent of a range function in any other language Basically, create an array of 9 elements, get the keys of those elements (0, 1, 2, ...) and then spread those keys out into an array. This lets me nicely map out the same element nine times using a single line of code. But... there's a catch!
Yep, that's not right! We have forgotten to add the row container. This means that instead of using my catchy one-liner from above we are going to have to perform an unholy combination of logic and layout. So we end up with the code below. It's a loop within a loop, as specified. Three rows, three columns. It's definitely not as pretty, but pretty wasn't the challenge.
```javascript
const boardLayout = [...Array(3).keys()].map((row) => (
<div className="board-row">
{[...Array(3).keys()].map((col) => {
const i = row * 3 + col;
return <Square value={squares[i]} onSquareClick={() => handleClick(i)} />;
})}
</div>
));
```
Replacing the original static layout with a new dynamic one has pros and cons. Pro: we reduce repeated code and make it more maintainable. Con: We replace a simple layout with much more convoluted logic, making the code much less readable. In this case I would always prefer the static layout but dynamic layouts are very common and are much more maintainable in larger apps.
## 3. Toggle
> Add a toggle button that lets you sort the moves in either ascending or descending order.
[Full Solution on Codesandbox](https://codesandbox.io/p/sandbox/3-toggle-button-g64wgf)
This one is super easy!
The layout for our moves currently looks like this: `<ol>{moves}</ol>`.
Here `moves` is nothing but an array of JSX elements. Why not swap them around like so `<ol>{moves.reverse()}</ol>`?
This is perfectly fine to do because `moves` isn't state. It is derived from state, i.e. `moves = history.map()`. Crucially, the map function creates a copy of the array that we can mutate as much as we like. No state problems here officer!
Obviously, that's not exactly everything. I'll add a single piece of boolean state, toggle it with a button and check it before reversing.
```javascript
return (
<div className="game">
<div className="game-board">
<Board xIsNext={xIsNext} squares={currentSquares} onPlay={handlePlay} />
</div>
<div className="game-info">
<ol reversed={isMovesReversed}>
{isMovesReversed ? moves.reverse() : moves}
<br />
<button onClick={() => setIsMovesReversed(!isMovesReversed)}>
{isMovesReversed
? "Show moves in ascending order"
: "Show moves in descending order"}
</button>
</ol>
</div>
</div>
);
```
And bingo! Note that `isMovesReversed` is used to control the order of the moves elements and the text on the button. Using ternarys for simple logic like this is perfectly fine.
One side note that I hadn't thought about is that this is an ordered list. It doesn't care what order the array is in. It just counts elements starting from 1. Luckily HTML came pre-bundled with a solution for that. `<ol>` in native HTML has a `reversed` attribute. We can just tie that to `isMovesReversed`. Beautiful native HTML!
## 4. Winning streak
[Full Solution on Codesandbox](https://codesandbox.io/p/sandbox/4-winning-streak-rjvvz8)
> When someone wins, highlight the three squares that caused the win (and when no one wins, display a message about the result being a draw).
The good news with this one is that all the heavy lifting of calculating the winner has already been done. The original solution contains the following.
```javascript
const lines = [
[0, 1, 2],
[3, 4, 5],
[6, 7, 8],
[0, 3, 6],
[1, 4, 7],
[2, 5, 8],
[0, 4, 8],
[2, 4, 6],
];
```
`lines` defines every possible combination that could be considered a straight line on the board. `calculateWinner` checks if all three have the same value and then returns that value. If we adapt `calculateWinner` we can have it also return the specific combination that won. Sounds super useful!
```javascript
return [squares[a], lines[i]];
```
This is what that looks like. The function now returns two values. So it's important we remember to destructure those two values everywhere we use it.
```javascript
const [winner, winnerLine] = calculateWinner(squares);
```
Like so. The first bit `winner` is used for it's original purpose. The second bit `winnerLine` will go on to do great things.
But first we have to consider the actual square component. How do we make it turn green? In react we can pass inline CSS as a simple object to the style prop.
```javascript
function Square({ value, onSquareClick }) {
return (
<button
style={{ background: "green" }}
className="square"
onClick={onSquareClick}
>
{value}
</button>
);
}
```
You will see every square has now turned green. That's what we wanted right? Damn! Ok, let's make it conditional on some prop `isWinner`. We'll figure out what that is later.
```javascript
function Square({ value, onSquareClick, isWinner }) {
return (
<button
style={isWinner ? { background: "green" } : {}}
className="square"
onClick={onSquareClick}
>
{value}
</button>
);
}
```
Uh-oh! It's later already. How are we going to tell this square if it's a winner or not? Remember when I said `winnerLine` would go on to do great things? Turns out we can just check the square number, and if it's in `winnerLine`, it's a winner!
```javascript
<Square
value={squares[i]}
onSquareClick={() => handleClick(i)}
isWinner={winnerLine && winnerLine.includes(i)}
/>
```
It's that easy! Note, we check if it exists first. `winnerLine` only exists once a winner has been determined.
One more thing. We need a stalemate message. Stalemate occurs when we reach the final move and there is no winner. I think the easiest way to achieve this is to give the board an extra prop `currentMove` and pass this down from App. Nothing super clever here just a few mutually exclusive if statements to cover all our cases.
```javascript
if (winner) {
status = "Winner: " + winner;
}
if (!winner && currentMove === 9) {
status = "Stalemate!";
}
if (!winner && currentMove !== 9) {
status = "Next player: " + (xIsNext ? "X" : "O");
}
```
It's not perfect but it will cover every case we will encounter here.
## 5. Move Locations
> Display the location for each move in the format (row, col) in the move history list.
[Full Solution on Codesandbox](https://codesandbox.io/p/sandbox/5-move-locations-y75hk6)
Like the prompt said. Display the board coordinates of each move.
Currently state is used to track two things
- `history`
- `currentMove`
We could add an extra piece of state. i.e. for each move we store a number that represents the location of that move. That's cool, but we would have to ensure we keep that new state in sync with the `history` at all times. Not so easy, especially in a larger app. We could also augment `history` into an object so it could store more detailed information. That sounds like a better option but can we go even better? Can we use what we already have?
By comparing the board between any two given moves we can determine the location of the move. All this information already exists in state, we just calculate what we want on the render. It's definitely putting some computation onto each render but I think here we will get away with it.
```javascript
function getMoveIndex(oldSquare, newSquare) {
if (oldSquare && newSquare) {
for (let i = 0; i < oldSquare.length; i++) {
if (oldSquare[i] !== newSquare[i]) {
return i;
}
}
}
return -1;
}
```
Basically, give me two squares: old and new. Run through the each element of the squares until you find two values that aren't the same. That's the index that changed! The default case (-1) is to cover the first move where a previous move does not exist.
```javascript
function indexToCoords(i) {
if (i >= 0 && i <= 8) {
return `[${Math.floor(i / 3) + 1}, ${(i % 3) + 1}]`;
}
return "";
}
```
It's trivial to go from an index value to a row/column value but it looks terrible. All that logic is neatly wrapped in `indexToCoords`.
```javascript
const coords = indexToCoords(getMoveIndex(history[move - 1], history[move]));
```
Finally, for each move in history we just calculate `coords` (as in coordinates). Now you can use `coords` wherever you want to display the string. Note that on the first pass `history[move - 1]` actually becomes `history[-1]` which is undefined. This is why we setup `getMoveIndex` to handle undefined input.
## Epilogue
I think these were useful challenges. Refactoring and retooling code forces you to make a million small design decisions every day. These exercises do a nice job of exposing them at a small scale. Hopefully all the little decisions I've made here are defensible. If not, fight me in the comments. What would you do differently?

Some years ago, I watched a movie called "[I, Robot.](https://en.wikipedia.org/wiki/I,_Robot_(film))" Later, someone told me it came from a [book](https://en.wikipedia.org/wiki/I,_Robot). So, I got the book and read it. This book talks about robots and AI from a very deep and thought provoking mindset. In the story, there are rules for robots. [Three Laws (rules)](https://en.wikipedia.org/wiki/Three_Laws_of_Robotics) for robots as defined by Isaac Asimov in this book are,
**First Law:** A robot may not harm a human or, through inaction, allow harm to come to a human.
**Second Law:** A robot must obey orders given by humans, except where it conflicts with the First Law.
**Third Law:** A robot must protect its own existence, as long as it doesn't conflict with the First or Second Law.
These rules make you think about big ideas, like what is right and wrong. The book also shows robots as smart and having feelings. This is interesting because we usually think of robots and AI as just machines. The movie is good, but the book makes you think even more. It makes you wonder about life and **what it means to be alive, even for a robot.**

## Prompt Engineering - Left side of the Wine Glass
Most of us are already familiar with PE but here I would discuss some of the advanced concepts with examples. Few of the open source tools you can use for prompt engineering are Manifest , Promptify and Chainforge
Lets look at how I am doing it in my CookGPT project.
**Prompt Selection** : Prompt selection involves choosing the most appropriate prompt from a set of candidate prompts for a given task or input query. Prompt selection methods may rely on custom rules, or user feedback to determine the optimal prompt for maximizing task performance.
```
User : I want a recipe for vegetable biryani
Mapped Prompt : Generate a classic recipe for Vegetable Biryani, including ingredients and step-by-step cooking instructions. Also provide calories and serving instructions.
```
**Prompt Compression :** Here the goal is to reduce the length and complexity of prompts without sacrificing the quality or relevance of model outputs.
```
User: Hey, I was wondering if you could maybe help me out with something? I'm craving a dish right now, you know? It's like, this Indian thing, with paneer and some kind of sauce, I think. Do you think you could give me a recipe for that?

1,843,722 | Is React Js Frontend Or Backend | React.js has taken the web development world by storm since its introduction in 2013. Developed and... | 0 | 2024-05-06T06:13:21 | https://dev.to/rukshanaitken/is-react-js-frontend-or-backend-4153 | react, frontend, backenddevelopment | React.js has taken the web development world by storm since its introduction in 2013. Developed and maintained by Facebook (now Meta), React.js has become one of the most popular JavaScript libraries for building user interfaces (UI). However, one question that often arises among developers, especially newcomers to React.js, is whether it is a frontend or backend technology.
To understand this, let's first define what frontend and backend mean in the context of web development.
## Frontend Development: The Frontend
- The frontend, also known as the client-side, refers to the part of a web application that the user directly interacts with. It encompasses everything that the user sees and interacts with in their web browser, such as the HTML, CSS, and JavaScript that renders the visual elements, handles user input, and provides interactivity.
## Backend Development: The Backend
- On the other hand, the backend, also called the server-side, is responsible for managing the data, logic, and functionality behind the scenes. It handles tasks like data storage, authentication, API integration, and business logic processing. The backend communicates with the frontend and sends or receives data as needed.
**So, is React.js Frontend or Backend?**
- The short answer is that React.js is a frontend library. It is primarily used for building user interfaces and rendering components on the client-side (in the web browser). React.js is not a complete solution for building web applications; it is a JavaScript library focused on the view layer (the UI) of an application.
- React.js allows developers to create reusable UI components and manage the state (data) of those components efficiently. When the state changes, React.js efficiently updates and renders the appropriate components in the browser, providing a smooth and efficient user experience.
- While React.js is a frontend library, it can be used in conjunction with various backend technologies and frameworks to build full-stack web applications. For example, developers can use React.js for the frontend and Node.js with Express.js for the backend, or React.js with a Python-based backend like Django or Flask.
- It's important to note that React.js is not limited to web development; it can also be used for building mobile applications (React Native) and even desktop applications (Electron).

Possible/Most common causes:
1. **Semantic Error**: The most frequent cause of a 422 error is when there is incorrect data logic or semantics, such as referring to an entity that does not exist. (e.g., a foreign key that points to a non-existent record).
2. **Missing Required Fields**: When the type of one or more input fields does not match what the server expects (e.g., string instead of integer, or vice versa).
How to Fix a 422 - Unprocessable Entity/Content?
1. **Validate the input**: Validate the input received by the server to ensure that it adheres to the defined structure and data types.
2. **Logging**: Implementing a logging mechanism for diagnosing the details of the error including the type of request, the origin of the request, and the time of the request will help in fixing the error.

**What is a Domain Object Model & how does it works:**
Domain Object Model (DOM) is a programming interface for web documents, such as HTML. The DOM represents web pages with a structure where each web page is an object representing a part of the document, this allows the programming languages to interact with the page. The DOM represents a document with a logical tree-like structure. Each branch of the tree ends in a node, and each node contains objects.
**The structure of DOM:**
The DOM tree structure is made up of a root node, which is the document and a series of nodes that represent the elements, attributes, and text content of the document. This means that each node in the tree has a parent node, except for the root node, and can have multiple child nodes.
**The DOM properties:**
a. Window Object: Window Object is object of the browser which is always at top of the hierarchy. It is like an API that is used to set and access all the properties and methods of the browser. It is automatically created by the browser.
b. Document object: When an HTML document is loaded into a window, it becomes a document object.
c. Form Object: It is represented by form tags.
d. Link Object: It is represented by link tags.
e. Anchor Object: It is represented by a href tags.
f. Form Control Elements: Form can have many control elements such as text fields, buttons, radio buttons, checkboxes, etc.

```js
// SAMPLE A
let a = 2;
let b = a;
console.log('a->', a, 'b->', b); // a-> 2 b-> 2
b= b*2;
console.log('a->', a, 'b->', b); // a-> 2 b-> 4
```
and then take a look at this
```js
// SAMPLE B
let a = {name: "Nelson M", age: 65 } ;
let b = a;
console.log('a->', a, 'b->', b);
// it affects the object that both a and b point to. This is because they both reference the same object in memory.
b.name = "Margaret Thatcher";
console.log('a->', a, 'b->', b);
```
They both end with changing variable `b` but look closely at how changing variable `b` affects `a` in both scenarios.
Do you see how variable `a` remains the same in Sample A but changes in Sample B even though we are seemingly doing the same thing in both scenarios? What is the reason for this discrepancy?
This is how data manipulation occurs in JavaScript. Changing a primitive and non-primitive data type in JavaScript happens differently.
What are primitives, you ask? According to [MDN](https://developer.mozilla.org/en-US/docs/Glossary/Primitive), "In JavaScript, a primitive (primitive value, primitive data type) is data that is not an object and has no methods or properties. There are seven primitive data types".
The primitive/non-primitive divide is the following in JavaScript
| Type | Examples |
| ----------- | ----------- |
| Primitive | string, number, bigint, boolean, undefined, symbol, null |
| Non-primitive | Array, Object |
When you assign a primitive, it is assigned by value. Non-primitives are passed by reference when being assigned. By the way, "reference value" is the correct term, but you will often hear just reference, and I will use those two interchangeably. Passed by reference value means that the thing you want to assign has a memory address, and the variable points to that memory address. So, that means that if you have multiple variables pointing to the same memory location and you make a modification, it changes for all those variables that are "referring" to it - pun not intended. That is akin to having a shared collaborative Google doc - if I make a change, you see the change and vice versa. The doc I work on does not have a life of its own, independent from yours, unless you decide to copy/duplicate it. Copying or duplicating the Google doc into its own independent entity is what happens when you pass by value.
Let's revisit the examples we've discussed to reinforce our understanding of variable manipulation in JavaScript.
```js
// SAMPLE A
let a = 2;
let b = a;
console.log('a->', a, 'b->', b); // a-> 2 b-> 2
b= b*2;
console.log('a->', a, 'b->', b); // a-> 2 b-> 4
```
Sample A
The value 2 is assigned to the variable `a`. The same value that went to `a` is assigned to `b`, but it has its own memory address and is entirely independent from that of `a`.
```js
// SAMPLE B
let a = {name: "Nelson M", age: 65 } ;
let b = a;
console.log('a->', a, 'b->', b);
// it affects the object that both a and b point to. This is because they both reference the same object in memory.
b.name = "Margaret Thatcher";
console.log('a->', a, 'b->', b);
```
Sample B
In non-primitives, `a` and `b` both point to the same thing. So when you change a property of `b`, it just changes the property of whatever in memory that `b` is pointing at. This happens to be the same thing that `a` is pointing at. Therefore, when you peek inside `a`, it will be identical to `b` because they really are the same thing.
So now let's make a little prediction -
So far, we know up to the part I wrote above. Let's see if we know enough to make a prediction based on what we have read. When you modify a primitive, e.g. number 2, it automatically is a reassignment to another thing. Because you are saying that the entirety of this 2 should change, unlike in the case of `{name: "Nelson Mandela", age: 65 }`, which has parts/properties that you can change. The 2 is the one and only value in and of itself, while the non-primitive value has changeable parts. So, in essence, when you do `b = 3`, it is a reassignment of `b` to a whole new thing.
So, this then begs the question of how it works when I want to reassign non-primitive `b` to a whole new thing. The prediction is that the non-primitive would behave similarly to a primitive reassignment if you were to change the full value. As in, if you were to do `b = {name: "Margaret Thatcher", age: 55 }`, the `a` would remain the original and `b` would have its own new value.
Let's put that to the test
```js
// non-primitive
let a = {name: "Nelson M", age: 65 } ;
let b = a;
console.log('a->', a, 'b->', b);
// a-> { name: 'Nelson M', age: 65 } b-> { name: 'Nelson M', age: 65 }
// it affects the object that both a and b point to. This is because they both reference the same object in memory.
b.name = "Margaret Thatcher";
console.log('a->', a, 'b->', b);
// a-> { name: 'Margaret Thatcher', age: 65 } b-> { name: 'Margaret Thatcher', age: 65 }
// you are reassigning b to a completely new object. Doesn't affect a because a is still pointing to the first object
b= {name: "Margaret T", age: 55 };
console.log('a->', a, 'b->', b);
// a-> { name: 'Margaret Thatcher', age: 65 } b-> { name: 'Margaret T', age: 55 }
```
The prediction checks out. So, in the case of reassignment, things work the same for both primitives and non-primitives; a new value is given. The variable is assigned a new value - unless you are assigning another variable e.g. `c` to `b`, in which case the same passing by reference value principle as mentioned above applies.
Let's go one step further. What happens when `b = a` but then later, `b = c`? Does changing `c` or `b` in this case affect `a`?
```js
// non-primitive
let a = {name: "Nelson M", age: 65 } ;
let b = a;
console.log('a->', a, 'b->', b);
// a-> { name: 'Nelson M', age: 65 } b-> { name: 'Nelson M', age: 65 }
// it affects the object that both a and b point to. This is because they both reference the same object in memory.
b.name = "Margaret Thatcher";
console.log('a->', a, 'b->', b);
// a-> { name: 'Margaret Thatcher', age: 65 } b-> { name: 'Margaret Thatcher', age: 65 }
let c = {name: "Donald Duck", age: 31 };
b=c;
// c is passed by reference value to become what b is pointing to. a remains intact
console.log('a->', a, 'b->', b,'c->', c);
// a-> { name: 'Margaret Thatcher', age: 65 } b-> { name: 'Donald Duck', age: 31 } c-> { name: 'Donald Duck', age: 31 }
//modify both b and c which should both be the same thing and thus should contain both changes
b.name= b.name+'1'
c.name= c.name+'1'
console.log('a->', a, 'b->', b,'c->', c);
// a-> { name: 'Margaret Thatcher', age: 65 } b-> { name: 'Donald Duck11', age: 31 } c-> { name: 'Donald Duck11', age: 31 }
```
As you can observe in the code snippet above, the answer is no. This is because the memory address that `b` is pointing to has been updated to be the address of what `c` is pointing to. This means that when `b` or `c` are modified, it modifies the same thing but `a` remains intact. Understanding this behaviour is crucial in JavaScript programming as it directly affects how your code operates.
We have examined how variable assignment is not uniform for all data types in JavaScript. We have also introduced the concepts of primitive and non-primitive data types and passing by reference or by value.
Check out this code snippet below and try to figure out what happens to the variables. Before reading the answer and explanation, think about it and take a guess. In the comments, let me know what you think would happen to `a`, `b` and `c` outside the function. Here is the [Stack Overflow link](https://stackoverflow.com/a/3638034/9767705) where you can find out more.
```js
function changeStuff(a, b, c)
{
a = a * 10;
b.item = "changed";
c = {item: "changed"};
}
var num = 10;
var obj1 = {item: "unchanged"};
var obj2 = {item: "unchanged"};
changeStuff(num, obj1, obj2);

This is going to be just a short article that I write as a way to protest to this annoying behavior in Chromium based browsers (Chrome, Edge, others?).
## Introduction
Well you must be used to autocomplete credit card information in your browser, and indeed it is a very useful feature.
## Buggy detection of credit card fields
The issue is that the following form that just asks the user for a date and a number (in Spanish), will trigger the browser's credit card functionality because it thinks I'm asking the user for a credit card.
```html
<form>
<label>Fecha</label>
<input type="text" name="Factura[fecha]">
<label>Número</label>
<input type="text" name="Factura[numero]">
</form>
```
So the algorithm is buggy. I'm not blaming the developers behind it because I'm sure it is complex but, they really need to consider if this is the best approach or they need to review how things work.
## Workarounds to solving this incorrect credit card fields detection
Well basically you can solve it with some hacks either by renaming the field names or the text of the label as these two are being used somehow inside the credit card field detection logic.
### Label based hack
This hack can be used ONLY if your input names do not contain the keywords, but only your labels do and so the labels are triggering the credit card menus.
```html
<form>
<label>Fecha</label>
<input type="text" name="Factura[field1]">
<label>Nú<span style="display:none">/</span>mero</label>
<input type="text" name="Factura[field2]">
</form>
```
### Input name based hack
```html
<form>
<label>Fe<span style="display:none">/</span>cha</label>
<input type="text" name="other_input_name">
<label>Nú<span style="display:none">/</span>mero</label>
<input type="text" name="other_input_name_2">
</form>
```
So depending on the fields on your form, you can implement one hack or the other, the label one is less problematic as it does not mess with your field naming, but depending on the case you might need to change the field names too.
**Bottom line: You can't have both "Fecha" and "Número" keywords combination inside your input names or labels.**
I have submitted an issue here to ask for a better solution: https://issues.chromium.org/issues/339033226

This is to ensure smoother rendering on web pages, where images transition from very pixelated to clear, rather than displaying a **'slow printing'** effect, particularly for visitors with low-speed internet connections.
## Comparison:
Here is an example of what I call "printing load" [1]:
And here is a smoother variant after re-saving in Photoshop [1]:
## Photoshop's "Save for web" feature
So I was wondering why Figma doesn't have an export tool like Photoshop's '**Save for Web**' feature, which has been available since at least 2007 and can be accessed with the shortcut **Alt + Shift + Ctrl + S** (or **Cmd + Option + Shift + S** for Mac).
Initially, I export images from Figma and then reopen all files in Photoshop to resave them with the necessary settings.
## Next step
Next, I am going to create a JS script that handles three variants of each image, tailored for different screen widths—namely, for widths above 1400 pixels, between 1400 and 700 pixels, and below 700 pixels. Depending on the browser window's width, the script dynamically assigns the appropriate image to the src attribute (or the background-image in CSS) in a lazy-loading manner to [enhance user experience](https://web-gate.org). However, I plan to write the JavaScript part later.
What steps do you take to optimize image loading and improve user experience?

Pre-funeral planning is a prudent and often overlooked step in ensuring peace of mind for both yourself and your loved ones. By taking the time to plan ahead, you not only ease the emotional burden on your family during a difficult time but also potentially save them from unnecessary financial strain. Here are three benefits of pre [funeral planning Lemon Grove](https://www.eastcountymortuary.com/locations#) that can save you money and emotional stress:
### Financial savings
Pre-funeral planning allows you to lock in today’s prices for funeral expenses, protecting your family from the inflationary pressures that may drive up costs in the future. Funeral costs have been steadily rising over the years, and by planning ahead, you can secure services and merchandise at current rates, potentially saving thousands of dollars. Moreover, pre-planning gives you the opportunity to explore different payment options, such as setting aside funds in a trust or purchasing insurance policies specifically designed to cover funeral expenses. By taking control of your financial arrangements now, you ensure that your family won’t be burdened with unexpected costs later, providing them with much-needed peace of mind during an already challenging time.
### Personalization and peace of mind
Pre funeral planning Lemon Grove allows you to express your wishes and preferences for your funeral arrangements, ensuring that your final farewell reflects your unique personality and values. Whether it’s choosing between burial and cremation, selecting a specific type of casket or urn, or deciding on the location and format of the service, pre-planning gives you the opportunity to make these important decisions in advance. By clearly outlining your preferences, you relieve your loved ones of the emotional burden of making these choices on your behalf, sparing them from potential disagreements or guilt over whether they made the right decisions. Knowing that your wishes will be honored brings a sense of peace and comfort, both to you and your family, allowing them to focus on grieving and healing without the added stress of uncertainty.
### Relieving emotional stress
Losing a loved one is an emotionally taxing experience, and having to make funeral arrangements amidst grief can exacerbate the stress and overwhelm felt by family members. By pre funeral planning Lemon Grove, you alleviate this burden and provide your family with a clear roadmap to follow when the time comes. From selecting the funeral home and arranging transportation to drafting obituaries and organizing the order of service, pre-planning ensures that all the necessary details are taken care of in advance. This not only streamlines the process but also allows your loved ones the space to mourn without the added pressure of logistical arrangements. By sparing them from these practical concerns, you enable them to focus on honoring your memory and finding comfort in each other’s presence during this difficult time.

It's no secret either that sometimes you'd... | 0 | 2024-05-07T17:51:13 | https://dev.to/fullstackdev/what-i-actually-do-to-stay-productive-34np | productivity, watercooler, discuss | It's no secret that sometimes work can be overwhelming. It's no secret either that sometimes you'd have so much work you don't even know where to start. It is like that for everyone, some people can manage just fine, and other times you just have to put in a little or A **LOT MORE** extra effort to get things done.
It took me some time to figure out what works for me, even the things and techniques I saw online looked stupid to me, and even though they wouldn't work until I tried them. I am now going to share what worked for me and to be completely honest what worked for me might now work for you, but that is **OKAY** don't be discouraged. It's a trial and error kind of thing, you keep trying things until you find and stick to what works for you.
# 1. Learn the ins and outs of your environment
Learn how your IDE/code editor works. Learn the **hot keys** and the navigation **shortcuts**. You might be asking "What's the big deal?". Trust me it is a big deal, using fewer mouse movements and more shortcuts will move a lot faster and lessen the chances of making errors, and will also reduce the strain on your wrist.
# 2. Make a list
"Make a list" as in **not** in actually making a list. Take a task and break it into smaller chunks. Take a chunk and estimate how much time it would take you.
- Prioritize Your tasks and break them down
- Do the chunk that takes less time
- If a chunk is taking more time than expected then **It can be broken into smaller chunks**
- Write off the finished chunks on the list.
# 3. Time management
When I first heard of this technique, I laughed at it and was very doubtful it would work. The **Pomodoro Technique** turned out to be very useful to me. We all know how it works, but in case you don't know it here's how it works.
- Set a timer for 25 minutes
- Work for 25 minutes without any interruptions
- After 25 minutes take a small break preferably between 3 to 5 minutes
- After 4 pomodoros, meaning after 2 hours of work take a longer break which would be between 20 to 35 minutes.
If you are a doom-scroller aka someone who likes to spend time on social media and get stuck scrolling you can use your longer breaks to scroll through social media😂
** Do not use the small breaks to scroll through social media it will interrupt your productivity. Instead, get up and move around. Walk around and drink water! It is important to stay hydrated to keep your mind sharp. More importantly, give your eyes a break from the screen during your short breaks.**
# 4. Notifications
Put your phone on Do not disturb while working or silence all the apps in your settings so that you do not receive notifications. Unless It is urgent calls or urgent texts do not interrupt your workflow, it will really be hard to regain focus after that. You can also leave your phone in another room (That doesn't mean you can open social media in the browser😂)
# 5. Stay Physically active
Try to find some time to work out during the day or at night. Working out doesn't just keep your body in shape but also keeps your brain sharp. Staying physically active will improve your memory and keep you creative. It is also a way to relieve your stress and keep your mental health in check.
# 6. Listen to your body
When you feel like you are tired and need a break, take a break. Do not push beyond what you can handle. It is a bad idea that will lead to burnout. Burnout is very real and it can be difficult to recover from if you do not listen to your body. So **When you feel like you need a break, take a break**.
At the end of the day, You have to learn how to prioritize your tasks and how to make your life easier. Work smarter not harder right? Experiment with all the techniques you can find you might find some that work for you if my advice isn't fit for you.
You can also try all the tools out there on the internet but Focus and dedication come from within you and not from outside and certainly not from an app.
I hope you found this useful! Thank you for reading! Would love to hear your opinions. | fullstackdev |
1,845,735 | Cannabis Insurance: 5 Steps Every Risk Management Plan Should Include | Is your risk management plan ready to go? A comprehensive plan is an integral part of doing business... | 0 | 2024-05-08T00:30:56 | https://dev.to/alpharoot2/cannabis-insurance-5-steps-every-risk-management-plan-should-include-35ka | Is your risk management plan ready to go? A comprehensive plan is an integral part of doing business for every company. No matter your revenue, team size, or quarterly growth, every business needs a risk management plan because every industry faces risks. These plans help you identify exposures, take action to cover them and identify gaps in your cannabis insurance policies. If you need a plan or help to figure out where to start, here’s how it works.
**What Is a Risk Management Plan? **
A risk management plan is a living document that identifies, assesses, and tracks areas of exposure in your business. This plan is critical because it details a crisis plan and action items for when risks become a reality.
Having a risk management plan is crucial to doing business in the cannabis industry. Risk is an unavoidable part of doing business in any industry, and having a solid risk management plan makes it easier to sleep at night knowing that you have a safety net for when things go south.
A risk management plan is a large document with several pieces. Putting this document together can seem overwhelming, but there is a system that works across all industries. Here’s what your risk management plan needs.
What Are the 5 Steps of a Solid Risk Management Plan?
Every risk management plan has five pieces to it. By tackling them one at a time, you break an enormous task down into small pieces that are easy to knock out and quickly form the foundation for a solid plan.
**First: Identification**
As our co-founder, Carl Niedbala always says, “We don’t know what we don’t know.” In other words, as a cannabis leader, you can’t cover exposures you don’t know about. Therefore, Identifying your risks is step one, and this is a big one.
Now is the time to put it all down on paper — every risk and area of exposure you can think of. Every business faces different threats, even within the same industry. While it may seem pessimistic to spell out every single risk you can think of, you must understand how and where you’re exposed to deal with it.
Be honest and calm here — naming risks doesn’t invoke them, so don’t leave anything out. You can start with the big or small risks — whatever gets the ideas flowing.
If you need help figuring out where to start, consult an expert. This could be a risk modeling software that uses simulations, flow charts, and mapping to spell out your risks at your own pace. Or this may be a person, a risk specialist with cannabis insurance expertise. The people on your team can also be resourceful; accountants, financial advisors, lawyers, and insurance brokers can all be valuable sources of information.
It also helps to identify the risks your company is already dealing with. An area of exposure doesn’t have to be earth-shattering to be a problem; what are your most common losses? You can also survey your employees or customers for insights.
**Second: Analysis**
Step two in building a risk management plan is analysis or assessment. Once you’ve identified your exposures, you must analyze them to see how much risk they present. Or, once you know where you can get hit, you need to figure out how bad it will hurt.
This stage can feel overwhelming because no one wants to play out every worst-case scenario they can imagine. But doing so sets you up for success if you use this information to cover your exposures.
Think of the worst-case scenario for every risk you identified; what kind of damage would it cause? Would you lose money, customers, employees, or all three? How long would it take you to recover, financially and reputationally? Using actuarial tables can be helpful here for a fresh and analytically accurate perspective.
**Third: Evaluation**
Once you know where you’re exposed and how badly it would hurt to experience a specific loss, it’s time to take action. In the evaluation stage, you decide if each risk is acceptable. Some small threats can be efficiently dealt with, while others are catastrophic. What risks fall under which category is up to you.
Put another way; this is the stage where you decide how to deal with your risks through the lens of likelihood and consequences. If a risk is unlikely with minor effects, you may simply leave it alone. But a risk with a high probability or significant consequences warrants treatment. Using your management team is essential to get different perspectives on different risks.
This stage is where you plan to cover your exposures. This could look like purchasing a cannabis insurance policy to give you a safety net, developing a crisis management plan, changing processes to avoid certain risks, or developing a recovery plan.
**Fourth: Tracking**
Tracking your risks is a vital part of the risk management plan. As mentioned above, this is a living document, so it needs to be updated as things change. Once you establish your risk management plan, track your risks and exposures. Note which risks become a reality and how your business recovers from them. This data is helpful long-term for consistently reassessing risks and identifying any weak points in your plan.
While dealing with risk is unpleasant, it can also be informative. With risk tracking, you can clearly see which risks can be avoided. Maybe your team needs more training, an internal process needs tweaking, or there’s an oversight in daily operations. Or perhaps a risk pans out because of an industry shift or a regulation change, and you need to pivot or add a new cannabis insurance policy
Risk tracking helps businesses work smarter, not harder.
**Fifth: Treatment**
Risk treatment is the most enjoyable stage of the risk management process because it’s the actionable step. Here is where you’ll take action to cover your exposures.
Treatment can look like adjusting an internal policy or removing a product from sale — it depends on your decision during the evaluation phase.
Cannabis insurance policies are one of the best ways to manage risks and sleep well with a safety net. Whether you need a theft policy, general liability, or something as specific as director’s and officer’s insurance, working with a cannabis insurance expert can help you cover your exposures and set your company up for success in the long haul.

GalaxyCoin exchange provides users with dozens of trading tools. Here, we introduce three fundamental principles that every trader should be aware of:
Spot Trading
As mentioned above, cryptocurrency spot trading refers to the process of buying and selling cryptocurrencies at real-time prices to generate trading profits.
Spot traders on the GalaxyCoin exchange typically engage in buying and selling a range of cryptocurrencies over short periods (hours or a day) to generate periodic short-term profits. On the other hand, in the GalaxyCoin application, this often involves holding crypto assets for the medium to long term.
Please read our help center articles to learn more about how spot trading works on the exchange.
Margin Trading
Margin trading involves trading financial assets using funds borrowed from a broker. This constitutes collateral for the broker's loan. On GalaxyCoin exchange, the margin is the difference between the total asset value and the loan amount.
A margin account is a standard brokerage account that allows traders to use their liquid assets as collateral for loans. The leverage provided by margin trading can amplify both profits and losses.
For example, if the margin is 0.1 BTC, but the trading value based on that margin is 1 BTC (i.e., 10x leverage), a 5% market movement in either direction will result in a profit or loss of 0.05 BTC (50% of the margin value).
Refer to our help center articles for detailed information on margin trading on the GalaxyCoin exchange and supported trading pairs.
Limit Orders and Market Orders
Market Orders are trades executed immediately at the current market price. Limit Orders set the highest or lowest price at which a trader is willing to complete a trade, emphasizing execution speed or a specific price point.
Limit Orders:
Limit orders are placed on the exchange at a specific limit price. The limit price determines the highest or lowest price at which a user wants to trade. When the market price reaches or exceeds the limit price, the order will be executed.
Limit orders can be filled at different prices to meet the order amount.
A sell limit order will be executed when the market price equals or exceeds the limit.
A buy limit order will be executed when the market price equals or falls below the limit.
Market Orders:
Buy/Sell Market orders are executed immediately at the best available price. This means market orders will accept any unfilled orders on the exchange order book to execute. Market orders may fill at different prices to meet the order amount.
Market orders are executed immediately at the best available market price, with any unfilled portion automatically canceled. Market orders always incur taker fees, which are fees generated by executed orders that remove liquidity from the exchange.
Conclusion:
These are the basics of GalaxyCoin exchange for beginners, including trading, cryptocurrency pairs, and essential functions required to execute trades on the exchange. For more tools offered by GalaxyCoinExchange, watch our videos on our YouTube channel, which provide tips and step-by-step guides from the GalaxyCoin help center.

1,846,028 | Errsole: The First Node.js Logger with a Built-In Dashboard | Logging is an essential component of any development project, especially in Nodejs. Usually,... | 0 | 2024-05-09T11:43:47 | https://dev.to/mrrishimeena/errsole-the-first-nodejs-logger-with-a-built-in-dashboard-4g8 | opensource, node, react, winston | Logging is an essential component of any development project, especially in Nodejs. Usually, developers have relied on solutions like [Winston](https://github.com/winstonjs/winston), [Pino](https://github.com/pinojs/pino), and [AWS CloudWatch](https://docs.aws.amazon.com/cloudwatch/).
However, these tools often have notable limitations: lacking seamless log viewing, requiring third-party services, or providing alerts with no context. [Errsole](https://github.com/errsole/errsole.js), the world's first open-source Node.js logger with a built-in dashboard, solves these issues.
## [Winston](https://github.com/winstonjs/winston)
Winston, a popular Node.js logging solution, allows users to save logs to a file or database. Although it's customizable, it lacks an integrated log viewer, forcing developers to use separate services or create custom tools for log analysis. This additional step can be both inconvenient and time-consuming.
## [Pino](https://github.com/pinojs/pino)
Pino shares many features with Winston, such as customizable logging levels and formats. However, similar to Winston, it requires separate solutions to effectively visualize or search logs, limiting its usability.
## [AWS CloudWatch](https://docs.aws.amazon.com/cloudwatch/)
AWS CloudWatch provides comprehensive logging, alerting, and monitoring features. However, it suffers from two major drawbacks:
**Complexity:** Setting up alerts/alarms requires expertise and significant configuration, making it less approachable for smaller teams.
**Alert Context:** Alerts generated by CloudWatch don't have log context, leaving developers uncertain about the nature and source of issues.
## [Errsole](https://github.com/errsole/errsole.js)
Errsole enhances Node.js logging by providing a seamless, built-in dashboard that's both easy to configure and user-friendly.
**Effortless Setup:** After installing Errsole and adding just two lines of configuration code, it automatically starts capturing console logs. The intuitive dashboard gives quick access to logs without the need for third-party services.
**Custom Logging Levels:** Errsole offers custom log levels (info, error, warn, alert), letting developers categorize logs based on their application's unique needs.
**Integrated Dashboard:** The dashboard is fully integrated into the app, and accessible via localhost or a dedicated domain.
**Log Viewing & Filtering:** View, filter, and search logs by log level and timestamp.
**Alerts & Integrations:** Set up custom alerts with detailed context, delivered via Slack or email. Proper context provides actionable insights, unlike the generic notifications from CloudWatch.
**Data Control:** Control data Time-to-Live (TTL) to optimize storage and retention.
**Team Collaboration:** Invite team members directly through the dashboard for seamless collaboration.
**Open-Source:** Errsole is open-source, offering advanced logging capabilities to developers of all levels.
## Conclusion
Errsole is raising the bar for Node.js logging by addressing long-standing challenges associated with traditional solutions. With its built-in dashboard, customizable alerts, and effortless setup, it's time to consider Errsole as the future of Node.js logging. Whether you're a solo developer or part of a large team, this comprehensive tool provides everything needed to monitor, visualize, and act on application logs effectively. | mrrishimeena |

Many... | 0 | 2024-05-08T17:56:53 | https://blog.dreamfactory.com/on-premises-vs-virtual-private-cloud-advantages-and-disadvantages/ | onpremises, virtualprivatecloud, api, database | Wondering which is the best way to host your business applications and IT infrastructure? Many enterprises are transitioning from on-premises software to cloud computing. On the other hand, several established companies are investing their capital in on-premises software. Both of these deployment models have advantages and drawbacks, and you can zero in on the right option by considering your specific requirements. The main difference between private cloud and on-premises hosting lies in the location and management of the infrastructure, with private cloud services being hosted and maintained by third-party providers off-site, while on-premises Infrastructure is physically located and managed in-house by the company itself.
Here’s the key takeaways from this article:
* On-premises hosting involves managing IT infrastructure and software on physical hardware located within a company’s facilities, offering greater control, customization, and compliance but at higher upfront costs and with scalability limitations.
* Virtual Private Cloud (VPC) provides a secure, cloud-based environment for IT infrastructure, offering scalability, cost-effectiveness, and flexibility, but depends on the cloud provider and may have security and customization limits.
* Hybrid cloud solutions blend on-premises and cloud environments, allowing businesses to leverage the control of on-premises hosting with the scalability of cloud services.
* Choosing between on-premises, VPC, and hybrid cloud requires considering factors such as technical expertise, budget, and data security requirements.
## What is On-Premises Hosting?
On-premises hosting refers to hosting IT infrastructure and software on physical hardware located within the company’s facilities, such as dedicated servers or a data center. The enterprise owns, manages, and maintains the setup. The hardware is present in-house, within the company’s premises; hence the name on-premises hosting. This deployment model allows the organization a greater degree of control and customization. However, it comes with high installation costs and requires maintenance and regular management, which makes it capital-intensive.
## Pros of On-premises Hosting
On-premises hosting is often preferred by organizations with specific security, compliance, or customization needs that can be better met by hosting the resources in-house. Let’s look at how organizations can leverage on-premises hosting.
### Offers Greater Control
With an on-premises environment, an enterprise can retain all its data and also get complete control of what happens to it. It allows them to configure their systems as they deem fit and implement custom security measures to safeguard sensitive information. This is especially beneficial in industries such as banking and healthcare, which deal with confidential customer data and have more privacy concerns.
### Provides the Highest Level of Customization
On-premise hosting provides greater customization than a [Cloud Environment](https://blog.dreamfactory.com/using-apis-to-build-robust-cloud-native-infrastructures/), as you have complete control over your hardware, software, and data. It enables enterprises to configure and customize the server and install any applications or software they need. It makes on-premise hosting ideal for organizations with specific security or performance requirements. Moreover, it also helps enterprises that need to integrate their web applications and websites with existing in-house systems.
### Costs are Predictable
Cost predictability is another significant advantage of on-premise hosting. As the enterprise owns and maintains the hardware and software necessary to run the applications, it gives them complete charge of the IT infrastructure. It implies that they can make informed decisions about the technology’s costs and budget accordingly.
Hardware and software costs are also generally a one-time expense, so on-premise hosting can provide a predictable cost structure. You can also better understand the costs associated with maintaining and upgrading your technology, as you have full control over the process.
### Ensures Compliance
Because the enterprise has complete control over the data assets, it can ensure that sensitive data is stored, processed, and transmitted in a compliant manner. VPCs, on the other hand, rely on the Cloud Service Provider’s underlying infrastructure and security measures. Also, on-premise hosting prevents third-party hosting providers from accessing your data.
## Cons of On-Premises Hosting
Although many enterprises benefit from on-premises hosting, it has some potential disadvantages.
### Limited Scalability
When compared with VPC, on-premises hosting has very limited scalability.Companies might find it challenging to expand their computing resources and infrastructure, leading to physical limitations when adding more storage and computing power. Moreover, these additions can be time-consuming and expensive.
Scaling can also lead to compatibility issues between the existing and the new hardware and software. These can cause outages and disrupt IT operations, adding to higher costs.
### High Upfront Costs
The major drawback of on-premises hosting is the enormous upfront costs associated with purchasing and setting up the software and hardware. Also, the enterprise needs a dedicated IT staff to manage the hardware and software, which costs more than outsourcing to a third-party service provider.
### Requires Regular Maintenance
Compared to VPC, where maintenance is the provider’s job, the business must perform timely maintenance to ensure smooth functioning. These maintenance tasks include backups, security updates, [Software Upgrades](https://www.forbes.com/sites/forbestechcouncil/2022/01/19/16-tips-for-ensuring-your-team-keeps-up-with-software-and-security-updates/?sh=1035c5d314a2), hardware replacement, and tuning performance. Apart from this, you need a dedicated team of IT personnel to carry out routine maintenance, which further adds to the costs.
### Demands Technical Expertise
On-premise hosting typically requires a higher level of technical expertise to install, configure, and maintain the different components compared to VPC. This is because the software is installed on on-premises servers and IT infrastructure owned and managed by the enterprise.
Businesses require a dedicated in-house IT team or a contract with third-party service providers to manage and maintain the software, hardware, and network components that make up the on-premise infrastructure. This costs an enterprise significant time, money, and resources.
## What are Virtual Private Clouds? (VPC)
Virtual private cloud (VPC) refers to a deployment model where the IT infrastructure and applications are hosted in a virtual environment that is provided by a cloud services provider, such as Amazon Web Services (AWS), Google Cloud Platform (GCP), or Microsoft Azure. In a VPC, A Virtual Network is created and isolated from the rest of the provider’s network. It provides a level of security and control similar to an on-premises deployment.
VPCs are often used by companies that require the flexibility and scalability of the cloud but also need to meet specific security and compliance requirements.
## Pros of VPC
Here are some of the key benefits offered by cloud solutions.
### Highly Scalable
VPC enables enterprises to launch and configure virtual servers, storage, and networking components. They can scale VPCs up or down effortlessly as needed, which helps businesses manage their computing resources and respond quickly to new demands and requirements.
Cloud computing offers multiple scaling options, such as auto-scaling, manual scaling, and load balancing. All these scaling methods are beneficial in ensuring optimal performance.
### Cost-Effective
VPC is often more cost-effective than on-premises hosting, particularly for businesses that do not have IT resources at their disposal. VPC providers take care of the maintenance and upgrades of the hardware and software, so enterprises can save on additional costs and resources for the maintenance and upkeep of their hosting infrastructure.
### Offers High Flexibility and Customization
Flexibility is another significant advantage of VPC, enabling a company to configure and manage its IT infrastructure. With cloud computing, your enterprise can create a custom network design that matches your needs. You can also customize the security options for your cloud infrastructure.
### Provides Easy Integrations
Cloud computing networks integrate seamlessly with other cloud services, such as Amazon Web Services and Google Cloud Platform. It allows enterprises to consolidate and manage their cloud infrastructure effortlessly.
## Cons of VPC
Like any technology, cloud solutions also have some drawbacks that must be considered carefully before deciding the best deployment solution. Some of the key disadvantages of VPC include the following.
### Dependence on Cloud Provider
The major shortcoming of cloud-based services is that they rely on the service provider. If the provider encounters any outages or technical difficulties, the systems may not be accessible to the enterprise.
### Security
Although VPC gives organizations a secure, isolated environment for hosting their applications and data, it also presents some security challenges. As cloud services are based on a shared infrastructure, they can be affected by cloud security breaches from other organizations using the same services. Moreover, small organizations with limited resources may find it difficult to manage security and compliance in a cloud computing environment.
### Limited Customization
Compared to on-premise solutions, it is challenging to customize VPC completely. Although it offers a certain degree of customization, many organizations cannot benefit from it. This happens because a business’s requirement may not be fulfilled with the customization options available. For instance, configuring network settings or including personalized hardware is a challenge with VPC. In addition, the enterprise’s compliance requirements may not be supported by the cloud service, making it difficult to customize.
A [survey conducted by IDG in 2020](https://www.infoworld.com/article/3561269/the-2020-idg-cloud-computing-survey.html) indicates that the cloud comprises a third of IT expenditures. Most companies plan to employ Cloud Computing for more than half of their infrastructure and applications. Although the recent trends favor VPC, on-premises hosting is still used by many organizations that need complete control over their data and applications.
Also, many organizations are moving toward a hybrid cloud solution, which combines the use of both public and private clouds. It allows businesses to take advantage of the scalability and cost benefits of public clouds while maintaining control and security over their sensitive data and workloads in a private cloud environment.
Before deciding on the best option for your enterprise, it is essential to consider technical expertise, budget, and data security requirements.

1,846,670 | Advanced Placeholder Replacement in C++: Handling Dynamic Data with Templates and Type Erasure | Introduction In many software development scenarios, especially in template engines,... | 0 | 2024-05-08T23:06:51 | https://dev.to/simopalacino/advanced-placeholder-replacement-in-c-handling-dynamic-data-with-templates-and-type-erasure-4fo | cpp, implementingtheworld, programming, token | ## Introduction
In many software development scenarios, especially in template engines, logging systems, or custom data processors, there's a frequent need to dynamically replace placeholders in strings with actual data. This can become complex when the data varies in type and quantity. Today, I'll show you how to elegantly handle this in C++ using templates, `std::any`, and type erasure techniques for a robust and type-safe solution.
## The Problem
Traditional methods of replacing placeholders often rely on fixed formats or limited data types. However, modern applications require more flexibility and safety, particularly when dealing with various data types and an unknown number of parameters at compile time.
## An example of the case and the result
The user wants to compose a message that have this template:
```text
Hello {{name}}, great work today! You've taken {{steps}} steps and burned {{calories}} calories. Remember: "{{quote}}"
```
We want to parse and replace with static or dynamic values, something like this:
```c++
PlaceholderManager pMgr;
pMgr.addPlaceholder(std::make_shared<Placeholder<Person>>(
"{{name}}", [](const Person& person) { return person.name; }));
pMgr.addPlaceholder(std::make_shared<Placeholder<Person>>(
"{{steps}}",
[](const Person& person) { return std::to_string(person.steps); }));
pMgr.addPlaceholder(std::make_shared<Placeholder<Person>>(
"{{calories}}",
[](const Person& person) { return std::to_string(person.calories); }));
pMgr.addPlaceholder(
std::make_shared<Placeholder<>>("{{quote}}", getRandomQuote));
```
We can set up a `PlaceholderManager` to hold this particular token that we want to make available to the user. And then we can use this manager to pass the input to be parsed and the list of arguments to pass to the callback that is responsible to give the actual string for that placeholder.
```c++
Person person{73, "Sheldon", 370, 1072};
const std::string res =
pMgr.replacePlaceholders(msg, {
{"{{name}}", {person}},
{"{{steps}}", {person}},
{"{{calories}}", {person}},
});
```
And the result must be like this:
```text
Hello Sheldon, great work today! You've taken 370 steps and burned 1072 calories. Remember: "Be a fan of anything that tries to replace human contact."
```
## Solution Overview
We'll tackle this challenge by creating a system that uses:
1. **Variadic Templates**: To accept any number and type of parameters.
2. **Type Erasure with `IPlaceholder` Interface**: To manage heterogeneous types in a uniform way.
3. **`std::any`**: To store and pass parameters of different types dynamically.
## Implementation
Our system starts with an interface `IPlaceholder` that all placeholder types will implement. This interface ensures that all placeholders can be managed polymorphically.
```c++
struct IPlaceholder {
virtual std::string resolve(const std::vector<std::any> &args) const = 0;
virtual const std::string &getPattern() const = 0;
virtual ~IPlaceholder() = default;
};
```
Each specific placeholder type is implemented using a template class that inherits from `IPlaceholder`. These classes can handle different types and numbers of arguments using variadic templates.
So here my `Placeholder` implementation, divided into small parts.
But we start with what we want to achive.
I want to be able to do something like this:
```c++
Placeholder ph("{{date}}", getSimpleDate);
```
where `{{date}}` is my placeholder, and `getSimpleDate` a function or callback that is called to replace that token.
So the first implementation of the `Placeholder` class may be this:
```c++
class Placeholder : public IPlaceholder {
public:
using FuncType = std::function<std::string()>;
Placeholder(std::string p, FuncType r)
: pattern_(std::move(p)), resolver_(std::move(r)) {}
const std::string &getPattern() const override { return pattern_; }
std::string resolve(const std::vector<std::any> &) const override {
return resolver_();
}
private:
std::string pattern_;
FuncType resolver_;
};
```
In this case we export the pattern that we can use in a regex replacement, and calling the `resolve` we simply call the callback that was set in the constructor.
Now the problem is when we pass a callback that takes one or more arguments and returns the string to place where the token is. This will enable us to do some dynamic replacing.
Again, I want to be able to write something like this:
```c++
Placeholder userIdPh("{{userId}}",
[](const Person& person) { return std::to_string(person.id); });
```
But how to modify our `Placeholder` class?
We need to add some templates for the arguments of the `resolver`, and a `std::vector` of `std::any` for the list of his arguments.
```c++
template <typename... Args>
class Placeholder : public IPlaceholder {
public:
using FuncType = std::function<std::string(Args...)>;
Placeholder(std::string p, FuncType r)
: pattern_(std::move(p)), resolver_(std::move(r)) {}
const std::string &getPattern() const override { return pattern_; }
std::string resolve(const std::vector<std::any> &args) const override {
if (args.size() != sizeof...(Args)) throw ArgCountError();
return invoke(args, std::index_sequence_for<Args...>{});
}
private:
std::string pattern_;
FuncType resolver_;
template <size_t... I>
std::string invoke(std::vector<std::any> const &args,
std::index_sequence<I...>) const {
return resolver_(std::any_cast<Args>(args[I])...);
}
};
```
I want to draw your attention to how I change the `resolve` method.
The two important steps here are:
1. I want to expand the arguments that I have in a vector, to be passed to the `resolver_` function;
2. I need to select the right element and cast it to the right type.
So, to expand the arguments I start to write the `resolver_` call with the expansion of the `Args` (the variadic template argument of the class):
```c++
resolver_(args[I]...);
```
To select the index while I'm expanding the template I use the `std::index_sequence<I...>` that it will be created by the expansion of `Args` (`std::index_sequence` is a helper alias template of `std::integer_sequence` for the common case where `T` is `std::size_t`).
Now we add the casting to get back the right type of the argument from the `std::any`:
```c++
resolver_(std::any_cast<Args>(args[I])...);
```
So, we need to pass to this function the vector of `std::any`s and the `index_sequence`:
```c++
template <size_t... I>
std::string invoke(std::vector<std::any> const &args,
std::index_sequence<I...>) const {
return resolver_(std::any_cast<Args>(args[I])...);
}
```
In the last, the `resolve` simply call the `invoke` method with the expansion of `Args` in order to create the `index_sequence`:
```c++
return invoke(args, std::index_sequence_for<Args...>{});
```
I also choose to add a check of the size of the vect of args, with the number of the variadic template `Args` using the `sizeof...` and throwing an exception `ArgCountError`:
```c++
if (args.size() != sizeof...(Args)) throw ArgCountError();
```
```c++
std::string resolve(const std::vector<std::any> &args) const override {
if (args.size() != sizeof...(Args)) throw ArgCountError();
return invoke(args, std::index_sequence_for<Args...>{});
}
```
### PlaceholderManager
Finally I introduced the `PlaceholderManager` class that keeps track of all placeholders and facilitates their replacement within strings. It matches placeholders to their data dynamically using `std::regex` and `std::map`.
I decided to escape the pattern, because like in our example above the tokens, e.g. `{{name}}`, use some character that must be escaped to be used in a regex. You can write your escape function, and let the user set his with the `setEscapingFnct` method.
The methods are:
1. `addPlaceholder(placeholder)`: The initial steps to set all the placeholders;
2. `replacePlaceholders(input, args)`: When we actually want to perform the tokens;
3. `setEscapingFnct()`.
```c++
class PlaceholderManager {
public:
typedef std::string(EscapingFnctTp)(const std::string &str);
void addPlaceholder(const std::shared_ptr<IPlaceholder> &placeholder) {
placeholders_[placeholder->getPattern()] = placeholder;
}
void setEscapingFnct(std::function<EscapingFnctTp> escapingFnct) {
escapingFnct_ = escapingFnct;
}
// @param input The string to be modified.
// @param args The map with vectors of arguments to pass to the functions of
// that placeholder.
// @return std::string The final string with all the placeholders replaced.
// Exceptions: May throw SubstitutionError to indicate an error condition.
std::string replacePlaceholders(
std::string input,
const std::map<std::string, std::vector<std::any>> &args = {}) {
for (const auto &itPh : placeholders_)
replaceEachPh(input, args, itPh.second);
return input;
}
private:
std::map<std::string, std::shared_ptr<IPlaceholder>> placeholders_;
// Exceptions: May throw SubstitutionError to indicate an error condition.
void replaceEachPh(std::string &input,
const std::map<std::string, std::vector<std::any>> &args,
const std::shared_ptr<IPlaceholder> &ph) {
static const std::vector<std::any> empty{};
const std::string &phStr = ph->getPattern();
std::regex regex(escapingFnct_(phStr));
auto it = args.find(phStr);
const std::vector<std::any> &vArgs = it != args.end() ? it->second : empty;
std::string fmt;
try {
fmt = ph->resolve(vArgs);
try {
input = std::regex_replace(input, regex, fmt);
} catch (...) {
throw SubstitutionError();
}
} catch (const ArgCountError &) {
}
}
private:
std::function<EscapingFnctTp> escapingFnct_{utils::escape};
};
```
### Extension of the PlaceholderManager
We can easly support our custom `PlaceholderManager` tailored to some functionality in our application. Add a predifined placeholder with corresponding function in the constructor.
```c++
class SimopPhMgr : public PlaceholderManager {
public:
SimopPhMgr() {
addPlaceholder(
std::make_shared<Placeholder<>>("{{date}}", getCurrentSimpleDate));
addPlaceholder(
std::make_shared<Placeholder<>>("{{iso8601}}", getCurrentIso8601));
addPlaceholder(std::make_shared<Placeholder<SomeEvent>>(
"{{eventName}}", [](const SomeEvent &event) { return event.name; }));
}
};
```
## In conclusion
This advanced placeholder replacement system in C++ offers both flexibility and type safety, making it ideal for a wide range of applications where dynamic text processing is required. By leveraging modern C++ features, we can ensure robust and maintainable code.
But it is clear that there are some observations:
1. For the `Placeholder` implementation there isn't a static type check at compile time for the vector of `std::any` and the actual types of the callback;
2. For `PlaceholderManager` the `resolve` is called for all the placeholders, and only if you don't pass the args vector for that placeholder, both the resolve and the regex are skipped. But for example if you have a placeholder with a callback without arguments, the resolve and the regex are performed;
3. Possibly we can pass also the return type to the Placeholder class for the `resolver`. If the conversion of that type to string is provided, automatically convert it to std::string (for example defining a template function for conversion, and providing template specializations of that).
So, there are many things to say about this simple but very effective implementation, and there are many ways to improve it.
I was thinking that if we want to achive the first observation about type check of the vector, we can use the `tuples` to pass the arguments.
Feel free to share your thoughts about this!

Whenever someone mentions this, the first thing that typically comes to mind for the speaker — if they are a developer — is Flask and FastAPI. This is because both are useful for creating small-scale data science web applications.
But which micro-framework should one use? Flask or FastAPI? Because both libraries offer similar features. Before discussing the pros and cons, let’s see what Flask and FastAPI are.
Flask is a web framework designed for creating web applications. It was developed by Armin Ronacher due to dissatisfaction with Bottle. Moreover, it doesn’t have ORM. Additionally, it is built on the Werkzeug toolkit and Jinja2 templating engine. This is what helps in creating lightweight web applications that have lower resource consumption.
Some pros of using Flask include:
1. Easiness — Although Flask has its syntax and jargon, it is relatively easy to understand compared to other frameworks.
2. Unit Testing — Flask supports unit testing. This helps developers in simulating different conditions for testing code.
3. Development Server — Flask provides a built-in development server. The best part? You can test your applications without deploying them into production.
4. Extend Functionality — Instead of just building an app from scratch, Flask helps you to improve the functionality of an existing app.
5. High Scalability — Flask is highly scalable. This means that even if you have a large app, you don’t need to worry about scalability.
However, like any other microframework, Flask has its cons. For instance, Flask lacks standardization, has limited tools, operates as a single-threaded system, and lacks out-of-the-box support for session management. Not only this, it can potentially have security vulnerabilities due to modules.
Now, what is FastAPI? FastAPI is also a micro-framework used for Python web development. It is also compatible with any database. Companies such as Netflix, Uber, and Zillow use FastAPI. The pros of FastAPI include:
1. Speed — FastAPI has a higher speed than Flask. In fact, it is one of the fastest web frameworks.
2. Concurrency Simplification — FastAPI simplifies concurrency by reducing the need for an event loop and async/await management.
3. Dependency Injection — Because of this, it becomes easy to make changes in code — classes aren’t directly dependent.
4. Built-in Documentation — FastAPI includes built-in documentation. This comes in handy when it comes to explaining software to others.
5. Built-in Validation — FastAPI provides built-in validation. This helps in reducing the need for external validation tools. Result? More concise code.
However, like any other microframework, FastAPI has its cons. For instance, it is not secure. The developer community is also small. However, this will change in the coming years.
So, which should you use? It depends entirely on your needs. If you require fast performance for asynchronous tasks and applications with high concurrency, FastAPI is the way to go. However, if you are a beginner seeking simplicity and flexibility, Flask would be more suitable.

## Problem Description
The page is narrow, how to adjust the configuration of VChart to make the pie chart occupy as much screen space as possible
## Solution
1. Cancel the default chart padding.
VChart sets a certain margin for all charts by default. You can configure `padding: 0` to cancel the default margin.
2. Adjust the outerRadius the pie chart.
By default, the pie chart does not fill the entire canvas, you can configure `outerRadius: 1` to set the outer radius ratio to the highest.
## Code Example
```
const data = [
{ value: 10, category: 'One' },
{ value: 9, category: 'Two' },
{ value: 6, category: 'Three' },
{ value: 5, category: 'Four' },
{ value: 4, category: 'Five' },
{ value: 3, category: 'Six' },
{ value: 1, category: 'Seven' }
];
const spec = {
type: 'pie',
data: [
{
id: 'pie',
values: data
}
],
outerRadius:1,
padding:0,
background:'#eeeeee',
categoryField: 'category',
valueField: 'value',
};
const vchart = new VChart(spec, { dom: CONTAINER_ID });
vchart.renderSync();
// Just for the convenience of console debugging, DO NOT COPY!
window['vchart'] = vchart;
```

1,847,284 | Visualization Module to Build Trading Strategy - First Acquaintance | Visual programming has always been an aspirational goal of software developers, even in the field of... | 0 | 2024-05-09T09:04:27 | https://dev.to/fmzquant/visualization-module-to-build-trading-strategy-first-acquaintance-2kc1 | visualization, trading, strategy, fmzquant | Visual programming has always been an aspirational goal of software developers, even in the field of quantitative trading.
Because the method of "what you see is what you get" in visualization reduces the technical threshold of programming development greatly.
Users no longer have to deal with a pile of boring codes. They just use their imagination and logical thinking to focus on the business itself.
You can realize a program you want. Isn't it amazing?
Let's get into the visual programming field of quantitative trading strategy together!
### Visual programming of the initial FMZ Quant
After logging in to https://www.fmz.com, register your account (if you are already registered, log in directly) and click: Dashboard ->Strategy ->Add Strategy.
We can see an initial visualization strategy.
It is only used to output the account asset information of the default configured exchange (the first exchange object added on the backtest or robot).
(See the figure below)
### Before we start learning how to use visualization, we can understand some design concepts of visualization.
1. Splicing
If you look carefully, you can see that modules have tenon (concave) and mortise (convex), i.e. modules can "connect" and "be connected".
If two modules represent functional codes that can be connected, then the tenons and mortises of the two modules will be attracted together when you bring them close.
2. Module setting and adjustment
Some modules have some special settable areas, for example:
You can drag the "Item" module on the left to the "Add" module, so that you can add a tenon (concave) position, thus adding a position for splicing text.
In this way, click the pinion to adjust and set the module.
3. Default input parameters of the module
Some modules need to input some parameters, which may be numeric values or strings.
If you do not add variables as input parameters of the module, the module will execute according to the default input parameters.
The square root calculation module like this outputs the calculation results of this module.
As you can see, if the input parameter position defaults, the default value 9 will be used as the input parameter to calculate the square root of 9.
Of course, if you want to use a variable module as the input parameter, you can splice the variable module into the tenon (concave) position directly.
4. Operation
The module can be clicked and dragged with the left mouse button.
Modules can be copied with ctrl+c and pasted with ctrl+v, just as convenient as copying and pasting code or text.
The operation area can be scaled with the mouse wheel, and all modules will be scaled larger or smaller.
Click and drag the blank position in the operation area to move the operation area.
The trash bin on the right side records the recently deleted modules.
The most important thing is that after splicing the module strategy, don't forget to click "Save".
###Introduction to visualization tool module
You can see that there are many module classifications on the left side of the visual editing area, and there are many visual modules available in each classification project.
There are 11 categories.
Util module:
1. Output information:
This module is usually used together with the module of text class, as shown below:
You can enter a string in the text module, so that when you run the Output Information module, the string content in the text module will be printed.
Backtesting:
Like JavaScript language code:
```
function main(){
Log("Hello, Blockly!")
}
```
2. WeChat push:
This module has the same appearance as the "output information", which is different from the one that pushes information to WeChat bound to the current account at the same time.
Like JavaScript language code:
```
function main () {
Log("WeChat Push!@")
}
```
3. Throw exception
Throwing exception module causes the program to issue an error, and then the program stops execution (without writing the exception handling code).
Similarly, in the JavaScript strategy, the main function executes the throw "string to output" function directly.
```
function main () {
throw "The first sentence throws an exception to stop the program!"
}
```
Backtesting results:
Generally, it is used more when debugging. For example, if you want the program to stop under certain conditions and print some data at that time for observation.
Or you can place an exception module in the code flow where problems may occur, let the program report errors, and find some errors.
4. Sleep
Sleep module
As in JavaScript strategy:
```
function main () {
Sleep(1000 * 5)
}
```
Test the sleep module:
Backtesting results:
5. Print returns
This module, just like the API function LogProfit on FMZ Quant Trading Platform, which prints the returns log and draws the return curve according to the input parameters automatically.
For example:
The execution of the backtesting is shown in the figure below:
The corresponding JavaScript strategy code is as follows:
```
function main () {
LogProfit(1)
Sleep(1000 * 5)
LogProfit(2)
Sleep(1000 * 5)
LogProfit(3)
Sleep(1000 * 5)
LogProfit(2)
Sleep(1000 * 5)
LogProfit(5)
}
```
It can be spliced at any position where you want to output return information.
6. Loop
Loop module can wrap a series of spliced module combinations, allowing the module combinations to execute the loop.
Test:
Backtesting results:
We can see that the module combination consisting of "print returns" and "sleep" will be executed continuously after the loop module is wrapped.
7. Loop execution every N seconds
The usage of this module is basically the same as that of the loop module. The only difference is that the module has its own sleep.
8. Precision processing
This module can be used when the variable module or numerical value needs to control the precision. The numerical value of the input parameter part will be output as the numerical value of the specified decimal place according to the settings.
For example, precision processing is performed on the value 3.1415926535897.
Backtesting display:
9. Clear Log
It is used to clear logs. Some logs can be retained according to the input parameters.
As in the API document:
```
LogReset()
```
10. Clear return log
It is used to clear the return log. Some logs can be retained according to the input parameters.
As in the API document:
```
LogProfitReset()
```
### The next are some frequently used tool modules
11. Function module for obtaining a certain attribute of the market
This tool module needs to be used together with the quotation module in the "Transaction Module Type", as shown in the figure:
Use the output information module to output the latest transaction price of the latest ticker market:
Backtesting display:
Like JavaScript strategy code:
```
function main () {
Log(exchange.GetTicker().Last)
}
```
12. The module that obtains the attribute of a bar of K-line data
This module also needs to be used together with the K-line data acquisition module in the "Transaction Module Type".
First, we create a variable module named K-line.
Then we obtain the K-line data, use the K-line data module to obtain it, and assign the value to the variable module: "K-line".
Then we use the list length module in the "List Module Type" to obtain the length of the K-line variable module, which is used to specify which bar on the K-line to obtain the data.
Splice them together, as shown in the figure:
The timestamp of the last K-line bar is printed when the backtest runs.
13. The module that obtains the data of an order in the order book
It also needs to be used together with the "Get Depth Data module" in the "Transaction Module Type".
The index is set to 0 and the selling order is set to obtain the information of the selling one order.
Like JavaScript strategy code:
```
function main () {
Log(exchange.GetDepth().Asks[0])
}
```
14. Module for obtaining an attribute in asset information
This module needs to be used together with the module of obtaining asset information.
For example: print the available currency of the current account
Backtesting display:
Like JavaScript strategy code:
```
function main () {
Log(exchange.GetAccount().Stocks)
}
```
15. Module for obtaining an attribute in order data
This module is used to obtain the value of an attribute in the order data, such as the price or quantity of selling one in the order book (example of No.13).
Backtesting results:
Like JavaScript strategy code:
```
function main () {
Log(exchange.GetDepth().Asks[0].Price)
}
```
It can also be used to obtain an attribute in the order information returned by the "Query Order Details Module" (to be explained in the advanced chapter).
16. The module to obtain the attributes of a position in the position information
Similarly, it should be used together with the "Get Futures Position Module". Note that the position data returned by the "Get Futures Position Module" is an array (list) that contains positions in different contracts and directions. Therefore, the index should be specified when using.
Having learned so much, let's combine a hedging operation, that is, hedging both short-term and forward contracts.
We make a positive arbitrage hedge, that is, open a short position contract for the forward contract, and open a long position contract for the recent contract.
Backtesting results:

1,847,522 | Assemblage: Automatic Binary Dataset Construction for Machine Learning | Assemblage: Automatic Binary Dataset Construction for Machine Learning | 0 | 2024-05-09T12:08:38 | https://aimodels.fyi/papers/arxiv/assemblage-automatic-binary-dataset-construction-machine-learning | machinelearning, ai, beginners, datascience | *This is a Plain English Papers summary of a research paper called [Assemblage: Automatic Binary Dataset Construction for Machine Learning](https://aimodels.fyi/papers/arxiv/assemblage-automatic-binary-dataset-construction-machine-learning). If you like these kinds of analysis, you should subscribe to the [AImodels.fyi newsletter](https://aimodels.substack.com) or follow me on [Twitter](https://twitter.com/mikeyoung44).*
## Overview
- Assemblage is a new technique for automatically constructing binary datasets for machine learning tasks.
- It aims to address the challenges of creating high-quality binary datasets, such as [Training Neural Network to Explain Binaries](https://aimodels.fyi/papers/arxiv/training-neural-network-to-explain-binaries), [Neural Assembler: Learning to Generate Fine-Grained](https://aimodels.fyi/papers/arxiv/neural-assembler-learning-to-generate-fine-grained), and [Advanced Detection of Source Code Clones via Ensemble](https://aimodels.fyi/papers/arxiv/advanced-detection-source-code-clones-via-ensemble).
- The technique involves several key steps, including data collection, feature extraction, and dataset construction.
## Plain English Explanation
Assemblage is a new way to automatically build datasets for machine learning models that work with binary files, such as software programs or other computer files. Creating high-quality datasets for these types of tasks can be challenging, as [discussed in related papers](https://aimodels.fyi/papers/arxiv/training-neural-network-to-explain-binaries).
Assemblage tries to make this process easier by automating many of the steps involved. First, it collects a variety of binary files from different sources. Then, it extracts important features or characteristics from these files, such as the structure of the code or the types of instructions used. Finally, it combines these features into a dataset that can be used to train machine learning models.
The goal is to create datasets that are diverse and representative of the types of binary files that the models will encounter in the real world. This can help improve the models' performance and make them more useful for practical applications, such as [detecting source code clones](https://aimodels.fyi/papers/arxiv/advanced-detection-source-code-clones-via-ensemble) or [generating fine-grained assembly code](https://aimodels.fyi/papers/arxiv/neural-assembler-learning-to-generate-fine-grained).
## Technical Explanation
Assemblage consists of several key components:
1. **Data Collection**: The system collects a diverse set of binary files from various sources, such as open-source software repositories, malware datasets, and proprietary software libraries.
2. **Feature Extraction**: Assemblage extracts a range of features from the collected binaries, including [low-level details like assembly instructions](https://aimodels.fyi/papers/arxiv/asdf-assembly-state-detection-utilizing-late-fusion) as well as higher-level characteristics like control flow graphs and function signatures.
3. **Dataset Construction**: The extracted features are then combined and organized into a structured dataset that can be used to train machine learning models. The dataset includes both positive and negative examples, ensuring a balanced distribution of classes.
4. **Evaluation and Refinement**: The quality of the constructed dataset is evaluated using various metrics, such as class balance, feature diversity, and model performance. The system then iterates on the data collection and feature extraction steps to improve the dataset, enabling the training of more accurate and robust models.
The key insight behind Assemblage is that by automating the dataset construction process, it can produce high-quality binary datasets at scale, overcoming the limitations of manual curation. This allows for the training of more powerful machine learning models for a wide range of binary analysis tasks, such as [malware detection](https://aimodels.fyi/papers/arxiv/gansemble-small-imbalanced-data-sets-baseline-synthetic), code clone identification, and binary program understanding.
## Critical Analysis
The Assemblage approach presents several advantages, such as the ability to create diverse and representative datasets, the scalability of the data collection and processing pipeline, and the potential for continuous refinement and improvement of the datasets. However, the paper also acknowledges some limitations and areas for further research:
1. **Generalization to Unseen Domains**: While Assemblage is designed to capture a wide range of binary file characteristics, there may be challenges in applying the system to specialized or domain-specific binary formats that were not well-represented in the training data.
2. **Robustness to Adversarial Attacks**: The paper does not discuss the robustness of the constructed datasets and models to adversarial attacks, which is an important consideration for practical deployment of binary analysis systems.
3. **Interpretability and Explainability**: The paper focuses primarily on the dataset construction process and does not explore the interpretability or explainability of the machine learning models trained on the Assemblage datasets, which can be crucial for understanding the decision-making process of these models.
4. **Ethical Considerations**: The paper does not address potential ethical concerns, such as the use of Assemblage for the analysis of malicious binaries or the implications of automated dataset construction on data privacy and bias.
Further research could address these limitations, explore the practical deployment of Assemblage-generated datasets, and investigate the societal impact of this technology.
## Conclusion
Assemblage presents a promising approach for automatically constructing high-quality binary datasets for machine learning tasks. By automating the data collection, feature extraction, and dataset construction processes, the system aims to overcome the challenges of manual dataset curation and enable the training of more accurate and robust binary analysis models.
The potential applications of Assemblage-generated datasets are wide-ranging, from improving the performance of [malware detection systems](https://aimodels.fyi/papers/arxiv/gansemble-small-imbalanced-data-sets-baseline-synthetic) to enhancing the understanding of binary program behavior. As the field of binary analysis continues to evolve, techniques like Assemblage can play a crucial role in advancing the state of the art and unlocking new possibilities for machine learning in this domain.

1,847,652 | 30-day Learning Challenge: Day 4— In and out of tech | Welcome back to the learning challenge that I’ve set out for myself, where I aim to document... | 0 | 2024-05-09T14:21:22 | https://dev.to/kervyntjw/30-day-learning-challenge-day-4-in-and-out-of-tech-4hbp | learning, programming, nutrition | Welcome back to the learning challenge that I’ve set out for myself, where I aim to document something new that I’ve learnt every single day for 30 days!
For today, I continued reading the nutrition-related book featured in Day 3’s article! The insights gleaned have been incredibly interesting, and are concepts that I have not come across before!
## Learnings (Nutrition)
For instance, one of the concepts mentioned at the beginning of the book was explaining why humans, like you and I fail so consistently when it comes to following a diet. In a nutshell, according to the author, it relates to how we are biologically programmed to act and seek out food when we are starved, leading to us spiralling out of control of our diet the moment we eventually succumb to the deprivation of our “sinful”, favourite foods.
It has been an amazing read so far, and I can’t wait to continue with the book to see what else I can learn in the upcoming pages.
Transitioning to the software engineer in me, I learnt even more today about how to write higher quality and sustainable code.
## Learnings (SWE)
From planning your architecture in advance, to understanding how to segment and compartmentalize large amounts of code into isolated containers/Lambdas (in AWS context), these are skills that will be continuously sharpened throughout my journey as a software engineer and I am no doubt excited to learn more!
A famous line I’ve heard from my previous tech leads, as well as from other senior software engineers, is that “if you fail to plan, you plan to fail”!
And I can’t tell you how much I agree with this.
Spending time to plan your code ahead of time, instead of straight deep-diving into writing code for your task/feature will save you immense of time down the line, as well as adjust your mindset to fit business requirements suited for that feature. Who knows, through this thought process and careful planning, you might even discover feature flaws/gaps in the requirements that you can highlight/discuss with your colleagues/peers!
As usual, do join me on this journey as well, and begin documenting your daily attempts at learning something new everyday. Trust me, you’ll shock yourself when you look back at how far you’ve come!
Do leave a comment down below or simply get in touch with me through my [email](mailto:kervynwork@gmail.com) if you wish to discuss about anything related to any of my previous articles! | kervyntjw |

* Reduced Costs: Automating tasks and processes via APIs can help businesses save money.
## 11 essential API trends for the upcoming year
Below are the top eleven API trends that you should be aware of for the upcoming year:
### Trend #1: The rise of serverless architecture
[Serverless Architecture](https://appinventiv.com/blog/what-is-serverless-computing/) is a type of cloud computing that allows you to run applications and services without having to manage or provision on-premise servers. This means you can focus on building your application rather than worrying about server maintenance. Serverless architecture is becoming increasingly popular as it can reduce costs and increase efficiency.
### Trend #2: The growth of API management
API Management is the process of creating, publishing, documenting, and managing your API ecosystem. With the increasing popularity of APIs, there is a growing need for tools to help businesses manage their APIs. API management tools can help companies automate tasks, such as monitoring API usage and managing access control.
### Trend #3: API-as-a-product
API-As-A-Product is a new trend that is gaining popularity. This approach to APIs involves treating an API like a product rather than simply a means of communication between different applications. For example, a SaaS company that provides an API for weather data could offer different “API products” based on the app, such as a real-time weather feed, historical weather data, or a weather forecast.
### Trend #4: The growth of artificial intelligence and machine learning
Artificial intelligence is becoming increasingly important in the world of new API development. AI can automatically generate documentation, monitor usage trends, and provide recommendations for improvements. By using AI, businesses can save time and resources that would otherwise be spent on manual tasks.
### Trend #5: APIs and the rise of chatbots
Chatbots are computer programs that simulate human conversation. They are commonly used to provide customer support or perform other tasks. Chatbots are growing in popularity, as they can give a more natural way for humans to interact with computers. Additionally, chatbots can be integrated with APIs to provide a more seamless experience for users. Chatbots have many use cases, including customer service, sales, and marketing. For example, a customer service chatbot could be used to answer questions about products or services.
### Trend #6: The growth of the Internet of Things
The Internet of Things (IoT) is the network of physical devices, such as cars, home appliances, and wearable devices connected to the internet. With the growth of IoT, there is a growing need for APIs that can connect devices to each other and data. For example, an API could connect a thermostat to a home’s heating and cooling system.
### Trend #7: The growth of edge computing
[Edge Computing](https://www.forbes.com/sites/forbestechcouncil/2022/04/25/edge-computing-what-is-it-and-why-does-it-matter/?sh=37d29c58f2cf) is a type of distributed computing that brings computation and data storage closer to where it is needed. This can improve performance and reduce latency. Additionally, edge computing can help reduce costs by reducing the need for bandwidth.
### Trend #8: API analytics
API analytics is the process of collecting, analyzing, and making decisions based on data from an API. These analytics can track usage trends, identify errors, and improve the overall performance of an API. With the rise of big data, API analytics is becoming increasingly important, and gives businesses the information needed to improve performance and scalability.
### Trend #9: The growth of API security
API security is becoming more critical as the number of APIs grows. API security refers to the measures taken to protect APIs from unauthorized access, misuse, or hackers. Standard API security measures include authentication, authorization, and rate-limiting.

1,849,586 | The Silent Revolution: How GenAI is Reshaping Cloud Tech☁️ | Lets explore how GenAI is conquering world and creatings its own world on the infra of Cloud. In... | 0 | 2024-05-11T11:19:11 | https://dev.to/mohit0303/the-silent-revolution-how-genai-is-reshaping-cloud-tech-4mjg | genai, aws, ai, cloudcomputing | Lets explore how GenAI is conquering world and creatings its own world on the infra of Cloud.
In the ever-evolving IT world, terms like Cloud, DevOps, and MLOps frequently surface. But the latest buzzword is GenAI.
So, what exactly is Generative AI?
Traditional AI can distinguish between objects — train a model with 1000 of cat and dog photos, and it’ll identify them accurately.
GenAI takes this a step further by creating something new.
Imagine a photo of a cat with the body of a dog, that’s GenAI in action.
It’s not just descriptive, it’s generative.
With advancements in data processing, model training, and computational power, GenAI is now poised to revolutionize various industries by generating new content like text, images, and audio that mimic human-created content.
GenAI leverages deep learning models, particularly those based on architectures like Generative Adversarial Networks (GANs) and Transformer models (like GPT for text and DALL-E for images), to produce outputs that are novel and realistic.(Just like above image)
Okay now, GenAI is with us and we can see it getting used in our day to day life as well. But to cook something you need vessel, to drive a car, you need road.
Same way to keep the GenAI alive and thriving, there must be a place, an infra where it is kept, stored, worked upon and trained.
That place is our friendly CLOUD.
And It has to be cloud as it’s clear the cloud’s vast storage and computing capabilities are vital.
In essence, the cloud is the backbone that supports and nurtures the growth of GenAI technologies.
If every field is using or trying to use GenAI, wont cloud with 100 of service, & being backbone of GenAI, will try to use GenAI? Ofcource Yes.
Implications of GenAI in the Cloud Domain
— — — — — — — — — — — — — —
As a Cloud Architect, integrating GenAI within your AWS environment can significantly boost innovation and efficiency:
🚀Innovation and Development
🌾Automating Content Creation: Use AI to automatically generate reports, documentation, marketing material, or user-specific content.
🌾Enhancing User Experience: Implement AI-driven chatbots or virtual assistants that provide human-like interactions for support and services.
🚀Enhancing Cloud Services:
🌾Personalization: GenAI can analyze user behavior and generate personalized recommendations for services or products.
🌾Security: Use AI to generate realistic cybersecurity simulations or training data, enhancing threat detection systems.
🚀Optimizing Operations:
🌾Resource Management: AI can predict workload trends and automatically adjust resources, optimizing cost and performance.
🌾Maintenance: Predictive maintenance can be enhanced with AI, predicting failures and automating routine checks without human intervention.
Other then these factors, there are so many GenAI tools as well present in AWS cloud.
GenAI Tools on AWS
AWS provides several tools and services that facilitate the use and deployment of Generative AI models:
🚀Amazon SageMaker: A comprehensive service to build, train, and deploy machine learning models at scale. It supports the latest AI frameworks, making it ideal for developing GenAI applications.
🚀AWS DeepComposer: Allows developers to get hands-on with Generative AI, particularly in music generation.
🚀AWS DeepRacer: Provides an interesting way to learn about reinforcement learning, a type of AI that could be considered under the broader umbrella of generative techniques.
🚀AWS DeepLens: Enables developers to integrate AI into applications using a deep learning-enabled video camera.
So in conclusion, GenAI is the hottest thing in our IT world, which is being nurtured & taken care in our Cloud world.
MOST IMPORTANT : A Friendly note for me and for you as well :
— — — — — — — — — — — —
These 2 tech, will for sure change how we are functioning at the moment.
Dont loose your mind, in thinking
“I will be laid off, Ai will replace me, i cant learn, i dont have skill”.
Embrace this change. Learning and adapting to new technologies like GenAI is a step-by-step journey.
If you’re worried about AI replacing jobs or questioning your ability to keep up, remember that every expert was once a beginner.
Stay curious and motivated — keep learning and moving forward.

1,849,601 | Choosing Your Accessibility UI Testing Library | Where To Start? If you are a web developer looking to level up your teams UI automated... | 27,341 | 2024-05-13T02:24:14 | https://dev.to/steady5063/choosing-your-accessibility-ui-testing-library-1o09 | a11y, automation, testing, webdev |
## Where To Start?
If you are a web developer looking to level up your teams UI automated tests to include accessibility what is the first thing you do? Google search of course!
When you google search though, you may find yourself a bit overwhelmed with where to start. There are numerous different accessibility testing libraries and all them seem to work their own way.
This is where developers tend to stop and go, "Well this is a lot, maybe ill add it later". That later, unfortunately, never comes.
Let's break down how you can chose the best testing library for your development team!
## What Are My Options?
There are multiple different packages that you can install into your project that allow you to include accessibility in your UI tests.
The ones that I highly suggest for usage in UI testing are as follows:
* [Axe-core](https://www.npmjs.com/package/axe-core) - Axe is an accessibility testing engine for applications and HTML based content. It is the most powerful rules engine for accessibility and contains the MOST integrations on the market. Examples of integrations include:
* Playwright
* Cypress
* Puppeteer
* [PA11y](https://www.npmjs.com/package/pa11y) - A command line node.js library that runs HTML code sniffer by default but also can run the axe-core rules as well!
* [Google Lighthouse](https://www.npmjs.com/package/lighthouse) - Node CLI package that runs various checks on your application, but also includes accessibility testing as well!
* [Wave by WebAIM](https://www.npmjs.com/package/webaim-wave) - The WAVE extension is one of the most powerful extensions for accessibility testing. The package allows you to include that powerful testing in a CLI.
All of these work differently in their own respective ways. So how do you know which one to choose?
## Making The Best Choice
When deciding which accessibility testing library you should use, it comes down to one thing. Ease of integration!
Whichever library fits into what your development team is doing for UI testing, should be the one you use.
For example, if your development team does integration level testing or end to end testing, then PA11y or Wave is a great library to use as it will fit directly into integration testing with its CLI or NodeJS commands.
An example of `pa11y` running:
``` javascript
test("Space Jam is accessible", async () => {
await pa11y('https://spacejam.com/1996').then((a11yResults) =>
{
expect(a11yResults.issues.length).toBe(0)
});
});
```
If you are already using a previous testing library like Lighthouse, then simply ensure the accessibility tests are running and are visible! They should be included in the output results.
Finally, if you want a specific integration into a testing framework such as Playwright or Cypress, use an axe-core integration. They are extremely easy to integrate into your current testing framework and can have you up and running in no time!
Example using `@axe-core/playwright`
``` javascript
test("is accessible", async () => {
const page = await context.newPage();
await page.goto('https://www.spacejam.com/1996');
const results = await new AxeBuilder({ page }).analyze();
expect(results.violations.length).toBe(0);
});
```
## In Summary
Choosing a library can be overwhelming to start. However, with a simple understanding of the top options available, you can get your development teams UI testing up and running with accessibility tests in no time! | steady5063 |
