## **3. Review Profiles and Portfolios**
Always spare time and look at the profiles and portfolios of the candidates. Search for the individuals with experience in the tasks for which you require assistance and look at their rating and their past clients’ feedback.
##
4. Conduct Interviews
Before meeting in person or having a phone/skype interview, define key objectives, inquire about their availability and interest, and ask meaningful questions in order to evaluate their communication style and working method as well as compatibility with what you require from an employee. Prepare questions that help you understand their experience and approach to work, such as: Prepare questions that help you understand their experience and approach to work, such as:
**When do you use quartiles?**
Have you worked on similar assignments in the past that you could specifically tell that you were handling similar tasks?
Describe your experience in dealing with pressure and constricted time to complete a task.
**5. Test Their Skills**
If you are working with several candidates, ASK THE SHORTLISTED CANDIDATES TO PERFORM A SMALL, PAID TASK BEFORE HIRING A DECISION IS MADE. Through this test you will be able to know their productivity, quality of work and how they adhere to directions given.

1,904,421 | Git | I. Add Commits to A Repo Configuration $ git --version $ git config --global... | 0 | 2024-07-01T08:25:46 | https://dev.to/congnguyen/git-2of0 | ## I. Add Commits to A Repo
- Configuration
```$ git --version```
```
$ git config --global user.name "<NAME>"
$ git config --global user.email "<EMAIL>"
$ git config --global color.ui auto
$ git config --global merge.conflictstyle diff3
$ git config --global core.editor "code --wait"
```
- Check configuration
```$ git config --list```
- To make a commit, the file or files we want committed need to be on the Staging Index. Command do we use to move files from the Working Directory to the Staging Index
```$ git add```
- Command takes files from the Staging Index and saves them in the repository
```$ git commit```
- Bypass The Editor With The -m Flag
```$ git commit -m "Initial commit"```
These Changes Were Not Committed on local let use this to know what those changes actually were
```$ git diff```
- Good Commit Messages
- Do
do keep the message short (less than 60-ish characters)
do explain what the commit does (not how or why!)
- Do not
do not explain why the changes are made (more on this below)
do not explain how the changes are made (that's what git log -p is for!)
do not use the word "and"
if you have to use "and", your commit message is probably doing too many changes - break the changes into separate commits
e.g. "make the background color pink and increase the size of the sidebar"
- To explain Why
##II. Tagging, Branching, and Merging
### **Tagging**
```$ git tag -a v1.0```
- Verify tag
```$ git tag```
- Delete tag - A Git tag can be deleted with the -d flag
```$ git tag -d v1.0```
- Adding A Tag To A Past Commit
```$ git tag -a v1.0 a87984```
### **Branch**
- Verify branch
```git branch```
- Create branch
```git branch sidebar```
- Create Git Branch At Location
```$ git branch alt-sidebar-loc 42a69f```
- Create branch + switch to it right after
```git checkout -b <new_branch_name> <at_SHA or at <name current_branch>```
_Will create the `alt-sidebar-loc` branch and have it point to the commit with SHA `42a69f`_
- Switch to desired branch
```git checkout sidebar```
_How this command works:
- Remove all files and directories from the Working Directory that Git is tracking
(files that Git tracks are stored in the repository, so nothing is lost)
- Go into the repository and pull out all of the files and directories of the commit that the branch points to_
- Show branch in log
```$ git log --oneline --decorate```
- Show all branch in gragh
```git log --oneline --decorate --graph --all```
- Delete branch, need to switch to other branch firstly (-D force delete)
```$ git branch -d sidebar```
### **Merge**
- There are two types of merges:
Fast-forward merge – the branch being merged in must be ahead of the checked out branch. The checked out branch's pointer will just be moved forward to point to the same commit as the other branch.
the regular type of merge
two divergent branches are combined
a merge commit is created
- Git merge to combine branch (merging some other branch into the current (checked-out) branch)
```$ git merge <name-of-branch-to-merge-in>```
- if you make a merge on the wrong branch, use this command to undo the merge
```$ git reset --hard HEAD^```
### **Undoing Changes**
- Update commit by modifying message or Add Forgotten Files To Commit
1. Make changes required file and do ```git add``` (if any)
2. Update message and commit file via ```$ git commit --amend```
The ```git revert``` command is used to reverse a previously made commit:
```$ git revert <SHA-of-commit-to-revert>```
This command:
1. Will undo the changes that were made by the provided commit
2. creates a new commit to record the change
### **Reset vs Revert**
_**Resetting** Is Dangerous_
- Reverting creates a new commit that reverts or undos a previous commit.
- Resetting, on the other hand, erases commits! (with flag --mixed (default to working dir); --soft; --hard)
However, Git does keep track of everything for about 30 days before it completely erases anything by ```git reflog``` command
💡 Create a backup branch on the most-recent commit so that I can get back to the commits if I make a mistake:
```$ git branch backup```
##III. Working with remote
A remote repository is a repository that's just like the one you're using but it's just stored at a different location. To manage a remote repository, use the git remote command:
```$ git remote```
It's possible to have links to multiple different remote repositories.
A shortname is the name that's used to refer to a remote repository's location. Typically the location is a URL, but it could be a file path on the same computer.
git remote add is used to add a connection to a new remote repository.
git remote -v is used to see the details about a connection to a remote.
- Git push (sync the remote repository with the local repositor)
```$ git push <remote-shortname> <branch>```
```$ git push origin master```
You'd like to include in your local repository, then you want to pull in those changes
```$ git pull origin master```
When you want to use ```git fetch``` rather than git pull is if your remote branch and your local branch both have changes that neither of the other ones has. In this case, you want to fetch the remote changes to get them in your local branch and then perform a merge manually. Then you can push that new merge commit back to the remote.
```$ git fetch origin master```
### **Working On Another Developer's Repository**
- Git log
```$ git shortlog -s -n```
```$ git log --author=Surma``` (tìm gần đúng tên)
```$ git log --author="Surma Lewis"``` (tìm chính xác tên)
```git log --grep=bug``` (Tìm text có chữ bug)
```git log --grep="this bug"``` (Tìm text có chữ this bug)
## NOTE
Before you start doing any work, make sure to look for the project's CONTRIBUTING.md file.
Next, it's a good idea to look at the GitHub issues for the project
look at the existing issues to see if one is similar to the change you want to contribute
if necessary create a new issue
communicate the changes you'd like to make to the project maintainer in the issue
When you start developing, commit all of your work on a topic branch:
do not work on the master branch
make sure to give the topic branch clear, descriptive name
As a general best practice for writing commits:
make frequent, smaller commits
use clear and descriptive commit messages
update the README file, if necessary
## Stay Syncing with source
When working with a project that you've forked. The original project's maintainer will continue adding changes to their project. You'll want to keep your fork of their project in sync with theirs so that you can include any changes they make.
To get commits from a source repository into your forked repository on GitHub you need to:
get the cloneable URL of the source repository
create a new remote with the git remote add command
use the shortname upstream to point to the source repository
provide the URL of the source repository
fetch the new upstream remote
merge the upstream's branch into a local branch
push the newly updated local branch to your origin repo

1,907,358 | GBase 8c Slow SQL Queries and Optimization | GBase 8c database supports slow SQL diagnostics and provides several parameter interfaces for... | 0 | 2024-07-01T08:25:06 | https://dev.to/congcong/gbase-8c-slow-sql-queries-and-optimization-4dli | database | GBase 8c database supports slow SQL diagnostics and provides several parameter interfaces for developers.
## 1. Slow SQL Related Parameters
### `track_stmt_stat_level`
Controls the level of statement execution tracking. This parameter has two parts, formatted as `'full sql stat level, slow sql stat level'`.
**full sql stat level**: Full SQL tracking level, with values OFF, L0, L1, L2.
**slow sql stat level**: Slow SQL tracking level, with values OFF, L0, L1, L2.
When the full SQL tracking level is not OFF, the current SQL tracking level is the higher level between the full SQL and slow SQL levels (L2 > L1 > L0).
### `log_min_duration_statement`
This parameter controls the logging of the duration of each completed statement when the duration is greater than or equal to a specified number of milliseconds.
When used together with `log_statement`, statements already logged by `log_statement` will not be logged again. Without syslog, it's recommended to use `log_line_prefix` to log PID or session ID, making it easier to connect the current statement message to the final duration message.
### `instr_unique_sql_count`
Increase this parameter to avoid the "missing SQL statement, GUC instr_unique_sql_count is too small." message.
## 2. Enabling Slow SQL
```bash
gs_guc reload -N all -I all -c "log_min_duration_statement=5s"
gs_guc reload -N all -I all -c "track_stmt_stat_level='OFF,L0'"
gs_guc reload -N all -I all -c "instr_unique_sql_count=2000"
```
## 3. Slow SQL Queries
Here are some example queries to detect slow SQL:
```sql
select * from dbe_perf.get_global_slow_sql_by_timestamp('2024-01-17 00:00:00', '2024-04-17 23:00:00');
select pid, now(), now() - query_start as query_duration, query
from pg_stat_activity
where datname = 'cloudx'
and pid != pg_backend_pid()
and state != 'idle'
order by query_duration desc;
```
### Causes of Slow SQL
#### (1) Lack of Indexes
In such cases, it is recommended to create indexes:
- **a.** Create indexes on columns used in join conditions and `WHERE` clauses.
- **b.** Create composite indexes for multiple column conditions in `WHERE`.
- **c.** Create indexes on columns with high selectivity.
- **d.** Create indexes on columns that require sorting.
#### (2) Index Invalidation
- **a.** Leftmost prefix rule for composite indexes is invalidated.
- **b.** `SELECT *` queries unnecessary fields.
- **c.** Predicates involved in calculations or functions.
- **d.** Use of `LIKE` for fuzzy search, e.g., `c1 LIKE '%aa'`.
- **e.** Use of `!=`, `NOT IN`, `NOT EXISTS`, `IS NOT NULL`, etc.
### System Configuration
#### (1) Memory-Related Parameters Need Optimization
- **`max_process_memory`**: Used with `enable_memory_limit`, limits the maximum memory available to the GBase instance. Recommended to be 70%-80% of system memory.
- **`shared_buffers`**: Size of the database system cache pool. If set too low, insufficient cache will cause excessive disk I/O. Recommended to be 25% of system memory.
- **`work_mem`**: Specifies the amount of memory for internal sorting and hash tables. If set too low, more temporary files will be written to disk.
#### (2) Optimizer-Related Configurations
Below are some commonly used parameters:
- **`enable_bitmapscan`**
- **`enable_mergejoin`**
- **`enable_sort`**
- **`enable_nestloop`**
- **`enable_hashjoin`**
- **`enable_seqscan`**
#### (3) Use of Hints
Specify the use of nestloop join method:
```sql
select /*+ nestloop(t2 t1) */
```
Specify query parallelism:
```sql
select /*+ set(query_dop 24) */

This is a time of infinite curiosity for your child, and their mind absorbs information and experiences like a sponge. While formal schooling may not be here just yet, you can nurture their love of learning with fun [activities at home](https://hikalpaa.org/)!
Engaging preschool children in creative activities at home during the early formative years enhances their development and strengthens the parent-child bond. Here are some fun and educational activities designed to stimulate learning while having fun:
Engaging Activities Inspired by [Hi Kalapa Preschool in Bengaluru](https://hikalpaa.org/):
1. Tactile Treasure Hunt: Fill a box with various labelled objects such as pine cones, cotton balls, and smooth pebbles. Cover your child’s eyes and let them think by touching the objects. This is a great way to introduce descriptive words and develop their sense of touch.
2. Nature Scavenger Hunt: Explore the local garden or your garden to collect leaves, flowers, and stones. This activity adds to Bengaluru’s natural beauty and makes playtime educational and engaging.
3. Letter and Number Hunt: Write letters or numbers on paper plates or cards and place them around the room or outside. Use signs or symbols to help preschoolers recognize and identify letters or numbers. This activity reinforces basic literacy and numeracy skills in a fun way.
4. Rainbow Rice: Colour rice with vinegar and food colouring. Have your child use pots, bowls, and spoons to create colourful sensory containers. This activity is both visually stimulating and great for developing fine motor skills.
5. DIY Puzzles: DIY puzzles offer a creative twist to traditional play. Let your preschooler draw or paint a picture, then cut it into pieces using safety scissors. They can then mix the pieces and challenge themselves to put the puzzle back together. These puzzles are entertaining and provide valuable learning experiences.
6. Finger Painting: Finger painting is a colourful and messy way for preschoolers to have fun. Set up a paint station with vibrant hues, and let their little fingers become brushes. Encourage them to mix colours and create handprint masterpieces on paper or personalised cards.
7. Straw Painting: Straw painting can be done by either splattering or blowing paint. Kids can splatter paint by picking up some in a straw and releasing it onto the paper, or they can put a drop of paint on the paper and use the straw to blow, creating fascinating patterns. This activity allows kids to experiment and uniquely create art.
These activities encourage the growth and development of preschoolers by inculcating the essence of [Hi Kalpaa Pre School in Bengaluru](https://hikalpaa.org/). Hi Kalpaa nurtures a passion for learning within a comforting and familiar home setting.

1,907,341 | Magic Cloud Security | Since we're attracting larger clients today than a year ago, with more complex needs for security, we... | 0 | 2024-07-01T08:07:56 | https://ainiro.io/blog/magic-cloud-security | security | Since we're attracting larger clients today than a year ago, with more complex needs for security, we wanted to write some words about our platform's security to ease our clients' minds.
[Magic Cloud](https://ainiro.io/magic-cloud) is the name of our platform. Magic is what allows us to deliver our [AI solutions](https://ainiro.io/) - So writing about our technology's security basically implies writing about Magic Cloud's security.
## 1. Cloudlets
We serve our AI platform as _"cloudlets"_. A cloudlet is basically a Kubernetes POD built from a Docker image. This implies there are no shared file system or configurations. Each of our clients have their own file system, their own set of configuration options, and their own private database. Magic Cloud is _not_ a multi tenant system, but a Docker container.
This makes it more difficult to deploy and manage, but increases security by several orders of magnitudes. It's not even possible in theory to have one client accessing data from another client for instance.
When we build these Docker images, we also create a unique user that the process runs within, which does not have write access to anything but the files and folders it should be able to write to. So having a security breach corrupting the underlying operating system is theoretically impossible.
We are also scanning these images automatically as an integrated part of our build process using automated tools such as [Snyk](https://snyk.io/).
In addition we're running our core server infrastructure on Linux, and we're always keeping the operating systems of our cloudlets updated, with recent versions, to avoid operating system related security issues.
On top of this, we're using a CDN network, and never exposing the physical IP address of our Kubernetes cluster publicly, encrypting the information sent from our CDN network to our Kubernetes controller plane, eliminating yet again an entire axiom of security related issues.
## 2. Database
In addition, the core database Magic runs on is not exposed to the internet at all. It's an SQLite-based database, only accessible from the file system within the cloudlet itself. This eliminates an entire axiom of security issues, resulting in that it's impossible for un-authorised users to get raw access to the database itself.
In addition we persist passwords into the database using BlowFish slow hashing, with per-record based salts, making it matemathically impossible to reverse engineer your password, even if some adversary gained physical access to the raw database files itself. BlowFish password hashing is the same technique that the NSA and the CIA uses to store passwords may I add.
SQL injection attacks is also effectively eliminated by using SQL parameters, making SQL injection attacks literally impossible.
## 3. Static code analysis and unit testing
Statically analysing code can eliminate an entire axiom of security related issues. Magic contains more than 1,000 unit tests, measuring test coverage, in addition to scanning the codebase for security issues during builds. Most projects in Magic have more than 98% unit test coverage. The industry requirement is 80%. We're outperformning the industry requirement by almost one order of magnitude.
For the record, less than 2% of all software is even capable of meeting the industry minimum requirement. We are outperforming the industry minimum requirement by one order of magnitude!
In addition, not one single method in Magic has a cognitive complexity above what's considered the maximum threshold required to make it easy to maintain. Cognitive complexity is a huge source for security issues, because once the code becomes difficult to understand, security issues becomes difficult to see.
## 4. Updating libraries
All 3rd party libraries we're using in Magic are kept updated. GitHub helps us here, by giving us warnings about updates we have to apply for security reasons - But we always makes sure we're using the latest security patches of any libraries we're using in Magic. In addition we're super conservative with what 3rd party libraries we pull into its core, and we are analysing all libraries for security related issues before we consider using them - And only if the library is found to be of super high quality applying all security related best practices we consider using these in the core of Magic.
For instance, Magic is using the latest stable release of .Net 8, and once .Net 9 becomes mature, we'll update the entire codebase to .Net 9. By using .Net we're also eliminating an entire axiom of security related issues, such as buffer overflow or buffer overrun. 98% of every single security breach we've seen in Windows and Linux the last 20 years are based upon buffer overflow issues. Because of the way .Net is built, experiencing a buffer overflow in .Net applications is literally impossible.
## 5. The best security I've seen
This is going to sound like bragging, but it is the truth. I've worked as an enterprise software developer for 25 years of my life, and Magic is the by far most secure system I have ever worked with.
The reason is quite simple, I'm its sole developer. Security related issues often sneaks into a system as a consequence of human software developers misunderstanding parts of the code base, and therefore unwillingly adds security issues, simply because of a lack of understanding how the existing code works. An entire axiom of security related issues originates from junior software developers. I've got 25 years of professional experience, and 42 years of software development experience in total - So I'm obviously _not_ a junior software developer.
Being the sole software developer on Magic, this entire axiom of security related issues simply vanishes, and becomes 100% irrelevant for us.
I have worked on finance related software projects responsible for moving billions of dollars annually, in addition to medical related software where security issues could literally be the difference between life and death. Still, Magic is the by far most secure system I have ever worked with in my entire life.
Magic's codebase is from 2019, and its core foundation was invented in 2013. This implies we've had more than 10 years to stabilise and mature our technology.
## 6. We're NOT ISO compliant
We are not ISO compliant, simply because there's no ISO standard in existence today, with requirements high enough for our platform - So we've not even bothered with ISO standardising our security. Security related ISO standards are often also counter productive for security. A great example of this is how they force you to install password managers, sometimes extremely insecure password managers may I add, adding a whole new axiom of potential things that can go wrong, effectively _increasing_ your attack surface - Instead of reducing it.
> We've evaluated all security related ISO standards, and they're simply not secure enough for us!
A great example of counter productive security measures can be illustrated by how a security firm contacted us about a security issue they claimed having found in our AI chatbot technology a couple of months ago. We analysed their report, reproduced the issue, and after careful examination of their findings, we concluded with that the only thing they had achieved was to literally _hack their own browser_ - And that there was no way their alleged security issue could in any ways affect other users besides themselves.
Since I didn't want to pay this security firm for having _"hacked their own browser"_, I checked out their website, and I found 3 security issues I reported back to them, 1 of which was severe.
In addition there's _one_ person in the world having access to our Kubernetes infrastructure, and that person is me - Period! This is because when it comes to security, I'm the most paranoid person you've ever met - And when it comes to security, paranoia is a _good_ thing!
On top of that, I have never physically logged into neither our Kubernetes cluster, nor our cloud hosting provider's admin dashboard, using anything but *Nix based operating systems, making spearphish attacks based upon keyloggers almost impossible. We also have 2FA turned on in every single part of our Kubernetes cluster infrastructure, in addition to on our codebase - Making it impossible to modify our code and inject malicious code without physically stealing my phone.
## 7. Disclaimer
So far (knock on wood), we've not have a single security related issue at AINIRO, and we are constantly doing everything we can to avoid breaches.
There are of course no guarantees when it comes to software security, because of the complexity of the domain - But we've applied dozens of layers of security, making security breaches highly unlikely.
If you are still not convinced, we allow for enterprise customers to study our codebase, assuming they're willing to pay for access to it, and sign the relevant IP contracts to avoid misuse or IP theft.
If you do, I'm 100% sure of that you'll see just as we do, that this is literally the most secure software system you've ever seen!
When that's said, please for the love of God use passwords with high amount of entropy that you don't use any other places as you create your root users in your cloudlet. 99% of every single intrusion ever seen in this world was because some human being chose to use _"admin123"_ as his password.
FYI, not even Facebook is hashing your password, implying there are 20,000 software developers working for Facebook that already knows your Facebook password - Implying if you're reusing this password on your cloudlet, any schmuck working for Facebook can access your cloudlet. Yes, true story, it was revealed almost a _decade_ ago by a leak, and there are few reasons to believe they've fixed these issues since!
The latter seems to be a general pattern in our vertical, where almost _none_ of the big social media companies are capable of avoiding storing your passwords in clear text, implying one breach at Facebook, and malicious hackers can access every single system you've ever used that same password on.
With Magic you can even use passphrases, entire sentences, increasing the entropy from 72 to the power of 8 to 12 to 150,000 to the power of 25 to 50, allowing you to use entire sentences as your password. If you do, the amount of energy required to brute force your password would exceed the amount of energy required to boil all the H2O (water) in the entire known universe!
And secure your client for the love of God. No amount of security features in Magic is ever going to save you from a keylogger you unwillingly downloaded because of _"clicking that love letter some random girl on the internet sent you a couple of days ago."_
99.99% of every single security breach originates from human failure and human flaws, and there's nothing we can do here except warning you about it, and teaching you how to avoid such human failures. However ...
> I can guarantee you that Magic is probably the most secure system you have ever used!
And ...
> I'm willing to bet 100 bucks on that if the CIA currently have an _"OpenAI management system"_ in use, it's with 99% certainty Magic! If it's not, they're doing something wrong!

1,907,336 | Implementing Multiple Density Image Assets in Flutter | As the mobile landscape continues to evolve, the range of screen sizes and resolutions across devices... | 0 | 2024-07-01T08:04:57 | https://dev.to/vincwestley/implementing-multiple-density-image-assets-in-flutter-3h05 | As the mobile landscape continues to evolve, the range of screen sizes and resolutions across devices has expanded significantly. From compact smartphones to expansive tablets, ensuring that your application’s visuals remain sharp and consistent across all these devices is crucial. This is where the concept of **multiple density image assets** comes into play, especially in the context of Flutter—a popular framework for cross-platform mobile development.
---
📄 **Understanding Screen Density and Image Assets**
Before getting into the details of Flutter it’s important to understand the basics of screen density and image assets:
- **Screen Density (DPI)**: Density refers to the number of pixels within a given physical area of the screen, typically measured in dots per inch (DPI). Devices with higher screen densities have more pixels per inch, which makes their displays sharper and clearer.
- **Image Assets**: These are the visual elements (like icons, buttons, and background images) used in an app. To appear sharp on screens with different densities, these assets need to be provided in multiple resolutions.
**Why Multiple Density Image Assets Matter**
**1. Enhanced Visual Quality**: High-resolution devices demand high-quality images to avoid appearing pixelated. By providing multiple density image assets, you ensure that your images look sharp and clear on any device, regardless of its screen density.
**2. Optimized Performance**: Using the appropriate image for each screen density can significantly improve performance. Loading images that are too large for a given screen’s resolution wastes memory and processing power, leading to slower performance and higher power consumption. Multiple density assets allow Flutter to select the most suitable image, optimizing both memory usage and performance.
**3. Consistent User Experience**: Ensuring that images look consistent across various devices is crucial for a seamless user experience. Whether your app is being used on a low-resolution screen or a high-resolution one, users should have a consistent visual experience. Multiple density image assets help achieve this by providing the right image for each screen type.
**4. Scalability Across Devices**: As new devices with varying screen resolutions are released, having multiple density assets makes your app scalable and future-proof. It ensures that your app can easily adapt to new hardware without requiring significant changes or additions to your image assets.
---
**Implementing Multiple Density Image Assets in Flutter**
Flutter simplifies the process of handling multiple density image assets through its asset management system. Here’s a step-by-step guide on how to implement them effectively:
**1. Preparing Image Assets**
For each image asset, prepare multiple versions at different resolutions. Commonly, these are:
- 1x for baseline resolution (mdpi)
- 1.5x for low-density screens (hdpi)
- 2x for medium-density screens (xhdpi)
- 3x for high-density screens (xxhdpi)
- 4x for extra-high-density screens (xxxhdpi)
For example, if you have an icon named `logo.webp` for a baseline resolution, you should also provide `logo@1.5x.webp`, `logo@2x.webp`, `logo@3x.webp`, and `logo@4x.webp`.
📄 - In this example, I'm using WebP for all the images because WebP offers better image compression. It's a good idea to use WebP for your images too. To learn more, visit this link.
**2. Organizing Assets in the Project**
Organize these assets in your Flutter project’s assets directory. A typical structure might look like this:
```
assets/
- images/
- logo.webp
- 1.0x/
- logo.webp
- 1.5x/
- logo.webp
- 2.0x/
- logo.webp
- 3.0x/
- logo.webp
- 4.0x/
- logo.webp
```
3. Defining Assets in pubspec.yaml
In your `pubspec.yaml` file, list the image assets. Flutter will automatically detect and use the appropriate resolution based on the device’s screen density:
```
flutter:
assets:
- assets/images/logo.webp
```
4. Using Assets in Your Flutter Code
When you need to use these assets in your Flutter widgets, simply refer to the base asset name. Flutter’s asset resolution system will automatically select the most suitable image:
```
Image.asset('assets/images/logo.webp');
```
**Best Practices for Managing Multiple Density Assets**
**1. Asset Compression**: Optimize your images for size without sacrificing quality. Tools like Respresso can help compress images while maintaining their visual fidelity and also splitting your image to all density.
**2. Regular Updates**: As new devices with higher resolutions are released, ensure that your assets are updated accordingly to support these new screens.
**3. Testing on Multiple Devices**: Always test your app on a variety of devices and screen densities to ensure that your assets render correctly and the user experience remains consistent.
---
⛔ **Trade-offs of Implementing Multiple Density Image Assets**
While multiple density image assets offer some benefits, they also come with certain trade-offs that developers should consider:
**Increased App Size**
In Flutter providing multiple versions of each image for different screen densities will inevitably increase the overall size of your app. This can be a concern for users with limited storage or slow download speeds. Large app sizes can also affect your app’s ranking and reviews, as users often prefer smaller, quicker-to-download apps.
📄 - The way multiple image densities are handled differs between native apps and Flutter. In native apps, using different densities can reduce the app's download size because only the appropriate density images are downloaded for each device. However, in Flutter, all image densities are included in the app package, which means the app download size isn't reduced by splitting images based on density.
**Development and Maintenance Overhead**
Managing multiple versions of each image can increase the complexity of your development process. You need to ensure that all images are updated consistently across all densities, which can be time-consuming. This also requires designers and developers to work closely together to maintain image quality and consistency across different resolutions.
**Balancing Trade-offs**
When deciding whether to implement multiple density image assets, consider the nature of your app and your target audience:
**- High-End Visuals**: If your app relies heavily on visual quality (e.g., a graphic-rich game or a photo editing app), investing in multiple density assets is crucial despite the increased app size.
**- Performance Optimization**: For apps that prioritize performance and efficient resource use, multiple density assets can reduce CPU load and power consumption, making the app more responsive.
**
- App Size Constraints**: If your app is targeted at regions with limited internet connectivity or users who are sensitive to download sizes, you might choose to use fewer resolutions or use methods that deliver assets as needed.
---
✨ **Conclusion**
Implementing multiple density image assets in Flutter is a strategic choice that balances visual quality, performance, and app size. By providing the right assets for each screen density, you ensure your app looks sharp and performs well across a variety of devices. However, this comes at the cost of increased app size and development complexity.
As a Flutter developer, it’s essential to evaluate your app’s specific needs and user demographics when deciding how to manage image assets. Whether you choose to implement multiple density image assets for optimal performance or streamline assets to minimize app size, the decision should align with your app’s goals and user expectations. By carefully considering these factors, you can deliver a high-quality user experience while maintaining efficient app performance. | vincwestley | |

1,907,335 | The Significance of Test Automation: Some unsaid Benefits | In the ever-evolving landscape of software development, the need for robust and efficient testing... | 0 | 2024-07-01T08:01:07 | https://mobilemarketingwatch.com/the-significance-of-test-automation-some-unsaid-benefits/ | test, automation | 
In the ever-evolving landscape of software development, the need for robust and efficient testing processes has become paramount. With the increasing complexity of applications and the demand for faster release cycles, manual testing alone is no longer sufficient. This is where test automation steps in, playing a crucial role in ensuring the quality and reliability of software products.
In this blog, we’ll delve into why test automation is essential, its importance, and the myriad direct and indirect benefits it brings to the table. Let us learn about advantages of automation testing.
**Why Test Automation**?
**Accelerated Time-to-Market**
One of the primary drivers behind test automation is the ability to expedite the software development lifecycle. Automated tests can run parallelly on different configurations, significantly reducing the time required for testing. This acceleration allows for quicker releases, meeting the demands of today’s fast-paced development environments.
**Enhanced Test Coverage**
Manual testing is limited by human resources and time constraints, making it challenging to achieve comprehensive test coverage. Test automation allows for the creation and execution of a vast number of test cases, ensuring that every aspect of the application is thoroughly tested.

Isso que nós nos perguntamos quando iniciamos nossa jogatina anual, o mais fácil seria abrir uma porta usando o redirecionamento de porta no roteador e “hostear” o servidor na própria máquina enquanto jogavamos, mas enfrentamos um problema: o provedor de internet. Atualmente existem mais computadores domésticos do que IPv4 no mundo, isso faz com que os provedores não forneçam um IPv4 único para cada rede contratada e dificulte o redirecionamento de porta/aplicações self-hosted na própria casa.
Foi ai que usamos o serviço de EC2 da AWS e um proxy reverso (FRP) para criar um tunelamento entre a rede pública e o servidor que estava rodando localmente na máquina, vamos recapitular tudo:
__________________________________________________________________________
##Configurar uma instância da EC2
Essa parte do trabalho foi realizada pelo @lucas_barros_1e6eb9a9ce38 onde ele me providenciou a chave privada para acessar via SSH a máquina virtual.
É importante liberar as portas 7000 (para conexão com o FRP) e a 25565 (porta padrão do servidor de minecraft).
##Configurar o FRP na máquina virtual
O FRP (Fast Reverse Proxy) é uma solução que facilita a criação de túnel de redes para acessar serviços internos de redes privadas através da internet.
Para isso você precisará baixar a versão mais atualizada do FRP compatível com o sistema operacional que você está rodando, no caso da máquina virtual será o linux_amd64.
No momento você pode baixar a versão mais atual através desse [link](https://github.com/fatedier/frp/releases/tag/v0.58.1)
Então você precisará acessar via SSH a máquina virtual da AWS com o comando
> **ssh -i “chave_privada.pem” dns-publico-da-sua-maquina**
E para fazer o download do FRP via terminal você pode usar o comando
> **wget <link-do-arquivo>**
Após descompactar e acessar o conteúdo da pasta, editaremos o arquivo **frps.toml** para termos certeza que o conteúdo dele é:
`bindPort = 7000`
Estamos especificando que a porta 7000 é a que será usada para a conexão entre o FRP do servidor com o FRP da máquina local.
Após isso rodaremos o comando abaixo para iniciar o serviço do FRP no servidor.
> **./frps -c ./frps.toml &**
O “&” é usado para rodar o serviço sem anexar a saída no terminal e assim podemos fechar a conexão com a máquina virtual da AWS sem parar o serviço do FRP.
Com isso podemos começar a configurar o serviço FRP localmente e também o servidor minecraft.
##Configurar o ambiente localmente
O primeiro passo é configurar o FRP na sua máquina local e para isso também iremos baixar através do mesmo [link](https://github.com/fatedier/frp/releases/tag/v0.58.1), porém no meu caso será a versão windows_amd64.
Após descompactar editaremos o arquivo frpc.toml que deve estar mais ou menos assim
```
serverAddr = "dns-publico-da-sua-maquina"
serverPort = 7000
[[proxies]]
name = "identificador"
type = "tcp"
localIP = "127.0.0.1"
localPort = 25565
remotePort = 25565
```
Salvando o arquivo e rodando o comando
> **frpc.exe -c frpc.toml**
É esperado que a conexão com o FRP que está rodando na máquina virtual da AWS seja estabelecida e portanto uma saída parecida com essa será exibida no terminal.
Como configuramos que a porta usada para o servidor minecraft é a padrão (25565) então idealmente todo o tráfego feito para a porta 25565 da rede da máquina virtual está sendo redirecionado para a porta 25565 da minha rede local, então basta apenas rodar o servidor do minecraft na porta 25565 da minha rede local que os jogadores terão acesso ao servidor de minecraft.
O IP público para o servidor será "dns-publico-da-sua-maquina":25565.
Boa jogatina!

Both operators are used to compare values, but they do so in distinct ways, leading to different outcomes. Let's delve into what sets these two operators apart and when to use each.
## `==` (Equality Operator)
The `==` operator, also known as the equality operator, compares two values for equality after converting both values to a common type. This process is called type coercion.
### Type Coercion
Type coercion means that JavaScript will try to convert the values being compared to the same type before making the comparison. This can lead to some unexpected results, as shown in the following examples:
```javascript
console.log(5 == '5'); // true
console.log(true == 1); // true
console.log(null == undefined); // true
console.log([] == false); // true
```
In these cases:
- `5 == '5'` is `true` because the string `'5'` is coerced to the number `5`.
- `true == 1` is `true` because `true` is coerced to the number `1`.
- `null == undefined` is `true` because they are considered equal in non-strict comparison.
- `[] == false` is `true` because the empty array is coerced to an empty string `''`, which is then coerced to `0`, and `false` is also coerced to `0`.
### When to Use `==`
Use `==` when you are certain that the type coercion will not lead to unexpected results, or when comparing values of the same type is not critical. However, it is generally advisable to avoid `==` due to the potential for bugs introduced by type coercion.
## `===` (Strict Equality Operator)
The `===` operator, also known as the strict equality operator, compares two values for equality without performing type coercion. This means that if the values are not of the same type, the comparison will immediately return `false`.
### No Type Coercion
Because `===` does not perform type coercion, the comparisons are more predictable and safer:
```javascript
console.log(5 === '5'); // false
console.log(true === 1); // false
console.log(null === undefined); // false
console.log([] === false); // false
```
In these cases:
- `5 === '5'` is `false` because the types (number and string) are different.
- `true === 1` is `false` because the types (boolean and number) are different.
- `null === undefined` is `false` because they are different types.
- `[] === false` is `false` because the types (object and boolean) are different.
### When to Use `===`
Use `===` when you need to ensure that the values being compared are both of the same type and value. This is generally the preferred operator because it avoids the pitfalls of type coercion and makes your code more predictable and easier to debug.
## Conclusion
Understanding the differences between `==` and `===` is essential for writing robust JavaScript code. The `==` operator can lead to unexpected results due to type coercion, while the `===` operator provides a stricter comparison that ensures both type and value are considered. As a best practice, use `===` to avoid the potential issues associated with type coercion and make your code more reliable and maintainable.
Happy coding! | manthanank |

## Para Meus Leitores
Se você está lendo esta página, é provável que esteja enfrentando dificuldades com o teste fechado de 14 dias envolvendo 20 testadores definido pelo Google e enfrentando desafios para reunir testadores. Quando desenvolvedores de apps Android se unem, superar a fase de teste se torna uma certeza. Meu app está aqui para ajudar com isso. Vamos cooperar para garantir que nenhum desenvolvedor tenha que interromper seu desenvolvimento por esses desafios. Preciso da sua ajuda para tornar isso possível.
## Funcionalidades Oferecidas pelo App
O app oferece funcionalidades de duas perspectivas principais:
* Como testador
* Como desenvolvedor de apps
### Como Testador
DevsPayForward auxilia você a testar outros apps de desenvolvedores, o que por sua vez garante que você receba testes de qualidade quando se tornar um desenvolvedor.
Principais características incluem:
* Listando apps que estão recrutando testadores
* Suporte para entrar como testador
* Monitoramento e pontuação das conquistas de testes
* Assistência com feedback durante os testes
#### Listando Apps que Estão Recrutando Testadores
Você pode visualizar uma lista de apps que estão atualmente recrutando testadores para testes fechados. Você pode escolher um app de sua preferência e conduzir testes.
#### Suporte para Entrar Como Testador
O método para se tornar um testador depende das configurações escolhidas pelo desenvolvedor do app, que podem incluir listas de e-mails e GoogleGroups. DevsPayForward suporta ambos os métodos. Se um app gerencia testadores via lista de e-mails, você precisa adicionar seu endereço de e-mail à lista. DevsPayForward facilita isso e suporta você até a instalação do app de teste. Para GoogleGroups, você pode se juntar ao grupo e se tornar um testador por conta própria, e então proceder com a instalação do app. DevsPayForward torna esse processo sem problemas, facilitando o início dos testes.
#### Suporte para Informações de Conta de Teste
Se o desenvolvedor do app forneceu informações de conta de teste, estas serão exibidas na tela de listagem do app. Você pode fazer login usando essas informações para avaliar facilmente as funcionalidades essenciais do app sem a necessidade de registrar uma conta própria.
#### Assistência com Feedback
Quando você testa o app de outro desenvolvedor, você pode lançar o app diretamente da listagem e fornecer feedback ao desenvolvedor do app imediatamente. O mecanismo de feedback suporta traduções, tornando mais fácil para testadores que precisam lidar com vários apps.
#### Monitoramento e Pontuação das Conquistas de Testes
Os apps que você declara como testados terão seu histórico de lançamentos monitorado, e os resultados serão quantificados como conquistas de teste. Isso ajuda a prevenir testes inadequados.
| Escolha Seu App Favorito | Suporte Contínuo Até o Feedback | Avalie no Seu Idioma Preferido |
|--------------------------|---------------------------------|---------------------------------|
|  |  | |
## Como Desenvolvedor de Apps
DevsPayForward ajuda você a conseguir que outros desenvolvedores testem seu app.
Características chave incluem:
* Registro de apps e assistência com o registro
* Confirmação/notificação de testadores
* Revisão de feedback
* Geração de texto para recrutamento de testadores
* Modo de teste (somente para o primeiro uso)
### Registro de Apps e Assistência com o Registro
Você pode registrar seu app para exibi-lo na lista de apps recrutando testadores. O registro requer prova de conquistas de teste. Durante o registro, assistência é providenciada para configurar automaticamente os ícones e nomes de app de acordo com seu app.
### Confirmação/Notificação de Testadores
Quando testadores registram seu app, você será notificado. A lista de endereços de e-mail dos testadores pode ser acessada a partir da tela do app. Se usando uma lista de e-mails, após adicioná-la, você pode completar o processo de registro para notificar os testadores de que eles foram aceitos e registrar sua aceitação.
### Revisão de Feedback
O feedback pode ser acessado a partir da tela do app. Feedback em idiomas desconhecidos pode ser traduzido, e você pode ver o tipo de dispositivo e a versão do sistema do usuário que forneceu o feedback, aliviando problemas com a reprodução de bugs devido a ambientes de testadores desconhecidos.
### Geração de Texto para Recrutamento de Testadores
Você pode compartilhar informações sobre seu app registrado como texto para garantir que ele passe nos testes com qualidade melhorada. Compartilhar informações necessárias e expandir a comunidade de desenvolvedores são essenciais para melhorar a qualidade do app.
### Modo de Teste
Para usuários de primeira viagem, um recurso de teste é suportado. Normalmente, registrar seu app requer testar apps de outros desenvolvedores. O recurso de teste permite registrar seu app mesmo que suas conquistas de teste sejam insuficientes, mas seu app não será visível para outros desenvolvedores até que um certo número de testadores seja recrutado. O status limitado é exibido na visualização onde você verifica seu próprio app. Se você achar DevsPayForward útil e desejar continuar usando-o, você deveria testar os apps de outros desenvolvedores e realizar a operação para remover as restrições da tela do seu app.
## Suporte Multilíngue
DevsPayForward suporta numerosos idiomas para tornar o app acessível para desenvolvedores em todo o mundo, especialmente aqueles de regiões com menos desenvolvedores. A partir de julho de 2024, o app suporta os seguintes 14 idiomas:
* Inglês
* Espanhol
* Francês
* Alemão
* Português
* Turco
* Árabe
* Hindi
* Indonésio
* Japonês
* Chinês Simplificado
* Chinês Tradicional
* Vietnamita
* Romeno
Novos idiomas serão adicionados continuamente. Se desejar uma tradução para um idioma específico ou encontrar uma tradução incorreta, por favor solicite através da seção de pedidos do app, e considerarei dar-lhe prioridade.
## Notas Importantes
### Testes Ativos e Feedback
DevsPayForward é um mecanismo para ajudar em assistência mútua, não uma ferramenta para vender testadores. Como desenvolvedores, os benefícios que você recebe são em troca do que você contribui. Por favor, vise proporcionar benefícios significativos para outros desenvolvedores. As revisões do Google estão se tornando mais rigorosas, portanto, a consideração mútua entre os desenvolvedores é necessária para garantir revisões bem-sucedidas.
### Status Público do App
Certifique-se de que seu app tenha passado pela revisão inicial e esteja pronto para testes fechados quando você o registrar. Se você registrar antes da revisão estar completa, a maioria dos testadores deixará o app antes que a revisão do seu app seja finalizada.
### Configurações Públicas para Grupos
Ao usar o Google Groups, sempre verifique as configurações públicas do grupo. Se não estiver configurado para permitir que qualquer pessoa se junte, seu app pode não ser testado corretamente.
### Configurações Regionais da PlayStore
Não limite as configurações regionais dos testadores na PlayStore. Como as configurações para Grupos, se os testadores não puderem acessar seu app, ele pode não ser testado adequadamente.
## Histórico de Desenvolvimento
Iniciei o desenvolvimento deste app quando o Google introduziu o requisito de testar com 20 testadores, pois eu tinha poucos conhecidos ou amigos para solicitar testes. O serviço era algo que eu desejava que existisse, então eu o criei para ajudar desenvolvedores independentes a se apoiarem mutuamente.
## Meu Objetivo
Meu objetivo com este app é criar um ambiente onde:
* Cada desenvolvedor independente possa lançar apps de alta qualidade de maneira eficiente.
* Novos desenvolvedores continuem surgindo, e os desenvolvedores não desistam do desenvolvimento de apps devido a fatores externos.
* Desenvolvedores de todo o mundo possam cooperar e se apoiar mutuamente.
Seria grato se mais desenvolvedores se juntassem a nós nesse esforço. Você também pode ler sobre o processo de desenvolvimento no meu [blog](https://zmsoft.org/blog/) se estiver interessado.

1,890,498 | Maintain chat history in generative AI apps with Valkey | Integrate Valkey with LangChain A while back I wrote up a blog post on how to use Redis as a chat... | 0 | 2024-07-01T07:57:54 | https://community.aws/content/2hxacO2sAyLAWy1eCFERO8d6Xrb | redis, database, machinelearning, go | > Integrate Valkey with LangChain
A while back I wrote up a blog post on how to use [Redis as a chat history component with LangChain](https://community.aws/content/2aq9ju6xvYtywGVbuPoWFTk5oK4/build-a-streamlit-app-using-langchain-amazon-bedrock-and-redis). Since LangChain already had Redis chat history available as a component, it was quite convenient to write a client application.
But, thats not the same with [langchaingo](https://github.com/tmc/langchaingo/) which is a Go port of LangChain. I am going to walk through how to do the same, but for [Valkey](https://valkey.io/) (not Redis). Valkey is an open source alternative to Redis. It's a community-driven, [Linux Foundation project](https://www.linuxfoundation.org/press/linux-foundation-launches-open-source-valkey-community) created to keep the project available for use and distribution under the open source Berkeley Software Distribution (BSD) 3-clause license after the [Redis license changes](https://redis.com/blog/redis-adopts-dual-source-available-licensing/).
> I also wrote about a [similar approach for DynamoDB](https://community.aws/content/2b4szPY94f8mCJa4eVIVH5jpfVj/lambda-ddb-app) as well as how to use [Valkey with JavaScript](https://community.aws/content/2hx81ITCvDiWqrAz06SECOvepoa)
Refer to **Before You Begin** section [in this blog post](https://community.aws/concepts/amazon-bedrock-golang-getting-started#before-you-begin) to complete the prerequisites for running the examples. This includes installing Go, configuring Amazon Bedrock access and providing necessary IAM permissions. The application uses the [Anthropic Claude 3 Sonnet model on Amazon Bedrock](https://docs.aws.amazon.com/bedrock/latest/userguide/model-parameters-claude.html).
## Run the chat application
The chatbot is a simple CLI application. Before we run it, let's start a Valkey instance using the [Valkey Docker image](https://hub.docker.com/r/valkey/valkey/):
```bash
docker run --rm -p 6379:637 valkey/valkey
```
Also, head over to https://valkey.io/download to get OS specific distribution, or use Homebrew (on Mac) - `brew install valkey`. You should now be able to use the Valkey CLI (`valkey-cli`).
Clone the app form GitHub and run the chat application:
```shell
git clone https://github.com/abhirockzz/langchain-valkey-chat-history
cd langchain-valkey-chat-history
go run *.go
```
Start a conversation - as you do that, all the conversation history will be stored in Valkey.
If you peek into Valkey, notice that the conversations are saved in a `List`:
```bash
valkey-cli keys *
valkey-cli LRANGE <enter list name> 0 -1
```
> Don't run` keys *` in production - its just for demo purposes
## Chat history component implementation
You can refer to the [complete implementation here](https://github.com/abhirockzz/langchain-valkey-chat-history/blob/master/valkey_chat_history.go). The component implements the `schema.ChatMessageHistory` interface methods in `langchaingo` and uses `List` data structure behind the scenes. Starting the application creates a new "chat session" is associated with a `List` - each new instance will be backed by a separate `List`.
Key methods that were implemented:
- `AddMessage` - Stores a conversation message, using [LPUSH](https://valkey.io/commands/lpush/)
- `Messages` - Retrieves all the messages in a conversation using [LRANGE](https://valkey.io/commands/lrange/)
- `Clear` - Deletes all messages in a conversation using [DEL](https://valkey.io/commands/del/)
## Conclusion
It's important to note that it's possible to use any Redis-compatible client with Valkey. I used the [go-redis](https://github.com/redis/go-redis) client, but (at the time of writing) there is work underway to build Valkey specific client libraries. Check the [Valkey GitHub org](https://github.com/orgs/valkey-io/repositories) to take look at the forks of existing Redis client libraries such as [valkey-go](https://github.com/valkey-io/valkey-go) (corresponding to [rueidis](https://github.com/redis/rueidis)), [iovalkey](https://github.com/valkey-io/Jackey) (corresponding to [ioredis](https://github.com/redis/ioredis)), [Jackey](https://github.com/valkey-io/iovalkey) (corresponding to [jedis](https://github.com/redis/jedis)) etc. These are very early days (at the time of writing), and it will be interesting to see the progress here!
Happy building! | abhirockzz |

Security: BitPower's impeccable security
BitPower, a decentralized platform built on the blockchain, knows the importance of security. In this rapidly changing digital world, security is the top priority for every user. BitPower is not just a financial platform, it is more like a solid fortress, based on five major security features to ensure that users' funds and information are foolproof.
First, decentralization is the cornerstone of BitPower's security system. All transactions and operations are automatically executed through smart contracts, and no one can unilaterally change the rules or manipulate funds. After deploying smart contracts, founders and developers, like ordinary users, have no privileges to intervene in the system. This decentralized design eliminates the risk of human manipulation and makes every transaction transparent and irreversible.
Secondly, BitPower emphasizes the transparency of transactions. All transaction records are permanently stored on the blockchain and can be viewed by anyone at any time. Users can clearly see the flow of funds and operation records, ensuring that everything is open and transparent. The immutability of the blockchain ensures the authenticity of the records, and users do not need to worry about information being tampered with or deleted.
Third, smart contracts are the core of BitPower's security system. Smart contracts are pre-written codes that automatically execute as long as the triggering conditions are met. This automated feature not only improves efficiency, but also greatly reduces the possibility of human error and fraud. Every operation of the user is completed by the smart contract, ensuring the security of funds and the accuracy of operations.
Fourth, BitPower adopts a strict risk management mechanism. The management and auditing of the platform are the responsibility of Comptroller, and each underlying asset has a specific collateral factor. Comptroller monitors and manages risks in real time through smart contract calls to ensure that every lending operation is carried out within a safe range. When the value of the asset drops to a certain level, the liquidation mechanism is automatically triggered to protect the interests of both borrowers and lenders.
Finally, BitPower operates through a global distributed network, further improving security. The platform has no single server or control center, and all data is distributed in nodes around the world. This distributed structure not only prevents single point failures, but also resists hacker attacks and other network threats. Users' funds and data are best protected in this network.
In summary, BitPower has created an impeccable security system through decentralization, transparency, smart contracts, risk management, and distributed networks. Users can safely operate on this platform and enjoy the convenience and benefits brought by decentralized finance. BitPower is not only a financial tool, but also a solid guarantee for user funds and information. Safe and worry-free, all in BitPower. | ping_iman_72b37390ccd083e | |

Privacy problems have grown in... | 0 | 2024-07-01T07:53:13 | https://www.zeeve.io/blog/how-zkrollups-and-fhe-rollups-tackle-privacy-challenges-differently/ | rollups, zkrollups | <p>One of the most serious challenges Ethereum faces today is privacy. Privacy problems have grown in priority as the number of users and apps on the network has increased. To solve these challenges, <a href="https://www.zeeve.io/appchains/polygon-zkrollups/">zk-rollups</a> and FHE rollups have emerged as some of the most viable options. The article will compare zk-rollups vs. FHE rollups, examining their advantages and applications for improving privacy.</p>
<h2 class="wp-block-heading" id="h-what-are-zk-rollups-btw">What are ZK Rollups, btw?</h2>
<p>To fully comprehend <a href="https://www.zeeve.io/appchains/polygon-zkrollups/">zk-Rollups</a>, one has to have a thorough understanding of zero-knowledge proofs.</p>
<p>A zero-knowledge (ZK) proof is a cryptographic method that enables one person (the prover) to convince another (the verifier) that a particular claim is true without revealing any details about the claim itself. </p>
<p>This is especially helpful in situations where it's important to verify authenticity or condition compliance without disclosing sensitive information. The name "zero-knowledge" refers to this technique, which allows transaction records to be validated without revealing any further information. Applications for it include private transactions, improving blockchain scalability, and identity verification, as shown by digital wallets and verifiable credentials.</p>
<p>A particular type of layer-two (L2) scaling technique called Zero-Knowledge Rollups (ZK Rollups) emerged to overcome the scalability issues with blockchains like Ethereum. To free up space on the main blockchain, they function by carrying out the majority of transaction processing and computation off-chain. </p>
<p>Subsequently, ZK Rollups adds zero-knowledge proof, a cryptographic validation of these transactions, along with a summary of them for the main chain. This verification confirms the transactions' legitimacy without necessitating the storage of every detail on the chain. ZK Rollups greatly increase the efficiency of transaction processing overall, which lowers wait times and transaction fees.</p>
<p><a href="https://www.zeeve.io/appchains/polygon-zkrollups/">zk-Rollups</a> are made up of two essential parts that are necessary for them to function:</p>
<li>On-chain contracts: On-chain contracts are essential to the zk-rollup protocol by establishing the operating guidelines. The primary contract and the verifier contract are the two main contracts in this segment. The primary contract serves as a rollup block repository, manages deposit monitoring, and enables essential changes. On the other hand, the verification contract has the responsibility of verifying the created Zero-Knowledge Proofs (ZKPs).</li>
<li>Off-chain virtual machines: These machines, which execute transactions on Layer 2 (L2) outside of the main Ethereum blockchain, are another essential component of the zk-rollup ecosystem. They run independently of the Ethereum network.</li>
<h2 class="wp-block-heading" id="h-what-are-fhe-rollups">What are FHE Rollups?</h2>
<p>A key aspect of the design of FHE Rollups is Fully Homomorphic Encryption (FHE), which allows calculations on encrypted data to produce outcomes identical to those on plaintext. Since its inception, Gentry's concept of FHE has taken several forms. This innovative method permits a wide range of activities, from basic arithmetic to intricate computations, while guaranteeing a high degree of data protection.</p>
<p>A straightforward illustration of FHE would be this: A data owner wants to protect their privacy while still transferring data to a cloud provider for processing. In this case, the data owner transfers the data to the server after encrypting it so that it is no longer readable. Without first decrypting the data to restore its legibility, the server can execute computations on it and return the encrypted results. </p>
<p>Because they have the secret key, only the data owner may decode the results, guaranteeing data security and process confidence.</p>
<p>Fully Homomorphic Encryption Rollups guarantee the confidentiality of all data during transmission, computation, and storage, preventing the ever-present possibility of sensitive data exposure. Because of the incredibly high level of privacy and security offered by continuous encryption, FHE Rollups are especially well-suited for sensitive data-handling applications like financial transactions and medical information.</p>
<p>FHE Rollups provide a scalable method for blockchain integration. They process massive amounts of encrypted data off-chain and guarantee that the outcomes can be safely validated before being reintegrated into the blockchain. </p>
<p>Once the necessary operations have been completed on the encrypted data, the encrypted results must be sent back to the data owner or another designated party for decryption. This technique improves overall efficiency and scalability by lowering the computing load on the blockchain itself while also guaranteeing privacy and security.</p>
<p>Let's examine how the discussion of zk Rollups vs FHE Rollups is contributing to advancements in privacy solutions.</p>
<h2 class="wp-block-heading" id="h-the-architecture-of-fhe-rollups">The Architecture of FHE Rollups</h2>
<p>The choice of whether to employ a Zero-Knowledge (ZK) Rollup or an Optimistic Rollup method forms the architectural cornerstone of FHE Rollups. This choice necessitates a careful balancing act between verification efficiency and proof speed.</p>
<p>Preferred for its speed, optimistic rollups presume transactions are valid by default and only do on-chain verification in response to disagreements. Although transaction processing is sped up with this method, any differences must be resolved by a robust fraud-proof mechanism. On the other hand, ZK Rollups provide more privacy by using Zero-Knowledge Proofs to protect transaction data, but at the expense of slower proving times.</p>
<p>An optimistic-based method within the encrypted domain is recommended, taking into account the difficulties of incorporating Fully Homomorphic Encryption (FHE) into the verification process. This approach acknowledges the existing barriers to generating effective ZK-based FHE Rollups while also being in line with FHE's fundamental properties.</p>
<h2 class="wp-block-heading" id="h-comparing-privacy-solutions-zk-rollups-vs-fhe-rollups">Comparing Privacy Solutions: zk-Rollups vs. FHE Rollups</h2>
<p>The origins of Zero Knowledge Proofs (ZKPs) and Fully Homomorphic Encryption (FHE) date back several decades. Although FHE was first proposed in 1978, it wasn't until 2009 that it became a reality. Conversely, ZK first appeared in the 1980s and served as the basis for a large number of cryptographic systems. Both FHE and ZK have had major improvements over time and are still essential to protecting data privacy.</p>
<h3 class="wp-block-heading" id="h-data-visibility-and-protection">Data visibility and protection</h3>
<p>The transaction data in zk-Rollups is protected from validators by zero-knowledge proofs, although the data isn't necessarily encrypted. This implies that even though validators cannot view transaction details, there is still a chance for the data to be compromised in the event that the proof system is hacked. </p>
<p>On the other hand, FHE Rollups keep data encrypted throughout. Continuous encryption guarantees that, even in the event of a compromised computing environment, the attacker can only access encrypted data that is useless without the decryption key. As a result, FHE Rollups are better able to safeguard data against leaks and illegal access.</p>
<h3 class="wp-block-heading" id="h-security-nbsp">Security </h3>
<p>By using cryptographic proofs, zk-Rollups minimize the danger of fraud and data exposure while providing excellent security. By guaranteeing the legitimacy of transactions without disclosing the specifics, a safe transaction environment is created. </p>
<p>But by guaranteeing that data is encrypted during every process, FHE Rollups go above and beyond for security. Ensuring that sensitive data is always safe, this end-to-end encryption guards against data breaches and unwanted access. Because of its strong encryption, in the comparison of zk Rollups vs FHE Rollups, FHE Rollups are especially well-suited for situations where the highest level of data confidentiality is required.</p>
<h3 class="wp-block-heading" id="h-privacy-guarantees-and-performance">Privacy guarantees and performance</h3>
<p>With zk Rollups, high privacy guarantees can be achieved by using ZKPs, which can be computationally demanding to prove but are very efficient in terms of verification. This implies that although the process of verifying transactions is quick and effective, the generation of the proofs themselves may take longer.</p>
<p>FHE Rollups, on the other hand, have a large computational expense but provide strong privacy by encrypting all computations. When compared to plaintext data, operations on encrypted data require more resources to complete. As a result, if we consider zk rollups vs FHE rollups, the latter offers superior privacy despite the fact that they can be slower and need more processing power.</p>
<h2 class="wp-block-heading" id="h-difference-between-zk-rollups-vs-fhe-rollups-nbsp">Difference between zk Rollups vs. FHE Rollups </h2>
<p>When evaluating zk Rollups vs FHE Rollups, there are a few important things to take into account. zk Rollups are known for their excellent efficiency when it comes to scalability. To do this, they group transactions off-chain and carry out as little on-chain verification as possible, enabling a high transaction throughput. However, because FHE requires more resource-intensive computations, FHE Rollups only provide limited scalability.
<p>Another area where these technologies diverge greatly is in privacy. FHE Rollups offer a moderate level of privacy, making them appropriate for situations where lone users rely on zero-knowledge proofs to keep information private. FHE Rollups, on the other hand, provide a far greater level of privacy. They are perfect for applications that demand strict security measures because they allow complex multi-party calculations on encrypted data.</p>
<p>There are differences in computation difficulty between the two as well. Since zero-knowledge proofs must be generated, zk Rollups are quite challenging but nonetheless rather effective. On the other hand, FHE Rollups have extremely high computational complexity. This is due to the fact that FHE necessitates greater processing power and time due to its extensive computation on encrypted data.</p>
<p>Another factor to consider is the verification time. Quick verification is advantageous for zk Rollups because zero-knowledge proofs are concise. FHE Rollups, on the other hand, have a moderate verification time because it is more difficult to verify the encrypted computations.</p>
<h2 class="wp-block-heading" id="h-projects-using-fhe-nbsp">Projects using FHE </h2>
<p>With the 2020 launch of TFHE and fhEVM, open-source cryptography company Zama elevated FHE ahead in the crypto space. Few projects currently take advantage of the Fully Homomorphic Encryption (FHE) rollups to increase privacy and security within blockchain applications. </p>
<p>Here are some notable ones:</p>
<h3 class="wp-block-heading" id="h-zama">Zama</h3>
<p>In early 2020, Hindi and Pascal Paillier, a well-known cryptographer and co-inventor of Fully Homomorphic Encryption (FHE), founded the open-source cryptography startup Zama. The company focuses on creating FHE solutions for applications utilizing blockchain technology and artificial intelligence (AI). Among Zama's products are the “TFHE-re library,” FHE compiler “Concrete,” “Concrete ML,” and “fhEVM.”</p>
<p>Zama has a three-phase plan for its development approach. The first phase (2022–2024) is dedicated to putting FHE for machine learning into practice, namely to create effective encrypted inference for neural networks. Phase 2 (2025–2027) intends to extend the use of FHE by incorporating analytics, encrypted search, and more extensive privacy-preserving computations. In the end, Phase 3 (2028–2030) aims to attain full FHE capabilities, allowing for practical performance in arbitrary calculations on encrypted data.</p>
<h3 class="wp-block-heading" id="h-fhenix">Fhenix</h3>
<p>Fhenix is driven by fhEVM, a private programming environment, and runs on a layer-2 network that is compatible with EVM. With this configuration, programmers can design apps on the Fhenix platform without needing to have a deep understanding of Fully Homomorphic Encryption. The method provides more comprehensive data protection, especially in cases where data comes from many sources, setting it apart from previous privacy solutions like ZK-SNARKs.</p>
<p>Zama's fhEVM technology lies at the core of Fhenix's capabilities. This makes it possible for developers to include FHE in blockchain applications with ease. As a result, blockchain technology has advanced and it is now possible to write encrypted smart contracts in Solidity without having a deep understanding of cryptography. </p>
<p>Fhenix's first development, the FHE Rollup, enables it to process private and sensitive data on Ethereum in a safe manner, increasing the blockchain's usefulness for a range of applications.</p>
<p>Their fheOS library contains the essential FHE logic. This is an encrypted computing library that includes pre-compiles for frequently used encrypted opcodes, like addition and multiplication, and comparison of two numbers. It allows network-running Smart Contracts to use FHE primitives inside the contract. This implies that encrypted data can be incorporated into the smart contract logic of dApps that are utilizing or running on Fhenix. </p>
<h3 class="wp-block-heading" id="h-inco">Inco</h3>
<p>Inco is a universal confidentiality layer and modular Layer-1 blockchain for Ethereum and other networks that use Ethereum security and fully homomorphic encryption (FHE). </p>
<p>Their fhEVM (FHE + EVM) removes the complexities of FHE and allows Solidity developers to create private dApps in 20 minutes or less by utilizing Solidity, the most popular smart contract language, together with Ethereum ecosystem tools like Metamask, Remix, and Hardhat. </p>
<p>The network provides a programmable and dynamic layer of decentralized identity (DID) that uses FHE to securely store private data on-chain and lets dApps query certain insights.</p>
<h2 class="wp-block-heading" id="h-final-thoughts">Final Thoughts</h2>
<p>Both zk Rollups and FHE Rollups endorse data privacy, although they function according to different ideas. Since FHE Rollups enable direct computations on encrypted data, data processing can benefit from them. In contrast, Zk Rollups prioritizes demonstrating knowledge of information without divulging it, which makes it perfect for safe transactions and identity authentication.</p>
<p>It is worth considering and conducting more studies to see if it is possible to combine homomorphic encryption with Zk in a single application to provide data security and identity protection and improve the ZKP and FHE algorithms. In the upcoming years, several advances are anticipated that could make data processing and storage even more private and safe.</p>

Everyone who's played an RPG knows "in-game" magic. The stuff of clerics, wizards, warlocks, enchanted weapons, magical traps, and cursed knickers.
You could easily argue that the GM's ability to invoke arbitrary fantasy-reality and the players' ability to give life to characters are forms of performative (real-world) magic too.
A third kind of magic might be in the remnants and re-tellings of the shared fiction.
Those of us who summarize fantastical happenings as or after they transpire get the opportunity for additional twists of fantasy-reality. It's more than magical. With the benefit of even a few seconds of hindsight, you have the chance to create an adaptation that might be funnier, pithier, more memorable, more apt, or more exciting than the original performance. Not to mention additional remixing and offshoots. It's art all the way down.
If magic is the ability to bend reality, let's not forget that "post-production" magicians get a chance to work wonders too, the kind evoked by that old Hollywood euphemism, "The Magic Store."

Als eine der führenden <strong><a href="https://junker-digital.de/webdesign-agentur-berlin/">Webdesign-Agenturen Berlin</a></strong> wissen wir, wie wichtig es ist, sowohl Above-the-fold- als auch Below-the-fold-Inhalte strategisch zu gestalten, um Besucher zu binden und Konversionen zu fördern.</p>
<p><strong>Verstehen von Above-the-Fold-Inhalten</strong></p>
<p>Above-the-fold-Inhalt bezieht sich auf den Teil einer Webseite, der ohne Scrollen sichtbar ist. Es ist der erste Eindruck, den Ihre Website auf Besucher macht, und damit eine hervorragende Gelegenheit, ihre Aufmerksamkeit zu gewinnen. Zu den Elementen, die in der Regel oberhalb der Falz zu finden sind, gehören Überschriften, Hauptbilder und erste Handlungsaufforderungen.</p>
<p><strong><em>Strategien zur Erlangung der Aufmerksamkeit oberhalb des Falzes</em></strong></p>
<p>Die folgenden Strategien helfen Ihnen bei der Optimierung von Above-the-fold-Inhalten, um eine maximale Wirkung zu erzielen:<br /> </p>
<ul>
<li><strong>Überzeugende Überschriften und Zwischenüberschriften</strong>: Verwenden Sie aufmerksamkeitsstarke Überschriften und Zwischenüberschriften, um die Aufmerksamkeit der Besucher auf sich zu ziehen und sie bei der Stange zu halten.<br /> </li>
</ul>
<ul>
<li><strong>Hochwertiges Bildmaterial und Multimedia</strong>: Binden Sie visuell ansprechende Bilder, Videos und Animationen ein, um ein intensives Erlebnis für die Besucher zu schaffen.<br /> </li>
</ul>
<ul>
<li><strong>Klare und prägnante Botschaften</strong>: Halten Sie Ihre Botschaften kurz und bündig und konzentrieren Sie sich auf die wichtigsten Vorteile und Funktionen Ihres Produkts oder Ihrer Dienstleistung.<br /> </li>
</ul>
<ul>
<li><strong>Platzierung und Gestaltung von Handlungsaufforderungen</strong>: Platzieren Sie die Handlungsaufforderungen strategisch so, dass sie hervorstechen und die Besucher zum nächsten Schritt ermutigen.</li>
</ul>
<p><strong>Verständnis für Below-the-Fold-Engagement</strong></p>
<p>Während der ohne Scrollen sichtbare Inhalt den ersten Ton angibt, ist der ohne Scrollen sichtbare Inhalt ebenso wichtig, um die Besucher beim Scrollen auf der Seite zu halten. Below-the-fold-Inhalte enthalten zusätzliche Informationen, Funktionen und Handlungsaufforderungen, die zur Interaktion und Konversion anregen.</p>
<p><strong><em>Strategien zur Erlangung von Aufmerksamkeit unterhalb der ersten Seite (Below-the-Fold)</em></strong></p>
<p>Konzentrieren Sie sich auf diese Strategien, um die Aufmerksamkeit am unteren Rand der Seite zu maximieren:<br /> </p>
<ul>
<li><strong>Fesselndes Storytelling und Inhaltsstruktur</strong>: Entwerfen Sie eine fesselnde Erzählung, die das Interesse der Besucher aufrechterhält und sie zum Weiterforschen anregt.<br /> </li>
</ul>
<ul>
<li><strong>Interaktive Elemente und Funktionen</strong>: Integrieren Sie interaktive Elemente, die zum Mitmachen anregen und die Besucher bei der Stange halten.<br /> </li>
</ul>
<ul>
<li><strong>Sozialer Beweis und Testimonials</strong>: Heben Sie Kundenreferenzen und Fallstudien hervor, um Vertrauen und Glaubwürdigkeit aufzubauen.<br /> </li>
</ul>
<ul>
<li><strong>Vorschläge für verwandte Inhalte und Navigationshilfen</strong>: Bieten Sie Vorschläge für verwandte Inhalte und eine benutzerfreundliche Navigation, damit Besucher Ihre Website besser entdecken können.</li>
</ul>
<p><strong>Mobile Optimierung für Aufmerksamkeitserwerb</strong></p>
<p>Mobile Responsivität bezieht sich auf die Fähigkeit einer Website, sich an verschiedene Geräte und Bildschirmgrößen, einschließlich Smartphones und Tablets, anzupassen und diese korrekt anzuzeigen. Mit der zunehmenden Verbreitung von Mobilgeräten ist die Optimierung Ihrer Website für Mobilgeräte nicht mehr optional, sondern unerlässlich. Mobile Nutzer haben andere Bedürfnisse und Verhaltensweisen als Desktop-Nutzer, so dass es wichtig ist, Ihre Webdesign-Strategien entsprechend anzupassen.</p>
<p><strong><em>Strategien zur Erlangung von Aufmerksamkeit für mobile Geräte</em></strong></p>
<p>Um Ihre Website für mobile Geräte zu optimieren, sollten Sie die folgenden Strategien in Betracht ziehen: Above und Below the Fold:<br /> </p>
<ul>
<li><strong>Vereinfachen Sie die Navigation</strong>: Der Bildschirmplatz auf mobilen Geräten ist begrenzt, daher ist es wichtig, die Navigation zu vereinfachen. Verwenden Sie klare und intuitive Menüoptionen und erwägen Sie die Implementierung eines Hamburger-Menüs, um Platz zu sparen und gleichzeitig Zugang zu wichtigen Seiten zu erhalten.<br /> </li>
</ul>
<ul>
<li><strong>Optimieren Sie die Seitengeschwindigkeit</strong>: Mobile Nutzer sind oft unterwegs und haben weniger Geduld für langsam ladende Websites. Optimieren Sie daher die Leistung Ihrer Website, indem Sie die Dateigrößen minimieren, das Browser-Caching nutzen und responsive Bilder verwenden, um schnelle Ladezeiten zu gewährleisten.<br /> </li>
</ul>
<ul>
<li><strong>Priorisieren Sie den Inhalt</strong>: Da mobile Bildschirme weniger Platz bieten, sollten Sie die wichtigsten Inhalte und Informationen in den Vordergrund stellen. Stellen Sie sicher, dass Schlüsselbotschaften, Handlungsaufforderungen und wichtige visuelle Elemente an prominenter Stelle angezeigt werden und ohne Scrollen leicht zugänglich sind.<br /> </li>
</ul>
<ul>
<li><strong>Verwenden Sie Responsive Design</strong>: Responsive Design ist ein Webdesign-Ansatz, der das Layout und den Inhalt einer Website automatisch an das Gerät des Nutzers anpasst. Durch die Verwendung von Responsive Design-Prinzipien können Sie sicherstellen, dass sich Ihre Website nahtlos an verschiedene Bildschirmgrößen, Ausrichtungen und Auflösungen anpasst.<br /> </li>
</ul>
<ul>
<li><strong>Optimieren Sie Formulare und Eingaben</strong>: Deshalb sollten Sie Ihre Formulare für Mobilgeräte optimieren, indem Sie die Anzahl der Felder reduzieren, mobilfreundliche Eingabefelder verwenden und Funktionen wie automatisches Ausfüllen und Eingabevalidierung implementieren, um den Prozess zu vereinfachen.<br /> </li>
</ul>
<ul>
<li><strong>Implementieren Sie mobile-spezifische Funktionen</strong>: Nutzen Sie mobilspezifische Funktionen wie Click-to-Call-Schaltflächen, standortbasierte Dienste und mobilfreundliche Gesten wie Streichen und Tippen, um das Benutzererlebnis zu verbessern und das Engagement zu fördern.</li>
</ul>
<p>Die Umsetzung der hier vorgestellten Strategien zur mobilen Optimierung kann dazu beitragen, ein nahtloses und ansprechendes mobiles Erlebnis für Ihre Nutzer zu schaffen.</p>
<p><strong>Erfolgsmessung und Iteration</strong></p>
<p>Die Messung der Effektivität Ihrer Webdesign-Strategien ist wichtig, um sicherzustellen, dass Ihre Website ihre Ziele erreicht und ein positives Nutzererlebnis bietet. Durch die Analyse von Daten und Nutzerfeedback können Sie verbesserungswürdige Bereiche identifizieren und Ihr Design verbessern, um die Leistung kontinuierlich zu optimieren.</p>
<p><strong><em>Wichtige Leistungsindikatoren (KPIs)</em></strong></p>
<p>Bevor Sie den Erfolg Ihres Webdesigns messen können, müssen Sie Leistungskennzahlen (Key Performance Indicators, KPIs) festlegen, die mit den Zielen Ihrer Website übereinstimmen. Gängige KPIs für Webdesign sind:<br /> </p>
<ul>
<li><strong>Absprungrate</strong>: Der Prozentsatz der Besucher, die Ihre Website nach dem Aufrufen einer einzigen Seite wieder verlassen. Eine hohe Absprungrate kann darauf hinweisen, dass die Besucher nicht finden, wonach sie suchen, oder dass der Inhalt oder das Design Ihrer Website verbessert werden muss.<br /> </li>
</ul>
<ul>
<li><strong>Verweildauer auf der Seite</strong>: Die durchschnittliche Zeit, die Besucher auf einer bestimmten Seite Ihrer Website verbringen. Eine längere durchschnittliche Verweildauer auf einer Seite kann darauf hindeuten, dass sich die Besucher mit Ihrem Inhalt beschäftigen, während eine kürzere Verweildauer darauf hindeuten kann, dass sie den Inhalt nicht überzeugend oder relevant finden.<br /> </li>
</ul>
<ul>
<li><strong>Konversionsrate</strong>: Der Prozentsatz der Besucher, die eine gewünschte Aktion auf Ihrer Website durchführen, wie z. B. einen Kauf tätigen, ein Formular ausfüllen oder sich für einen Newsletter anmelden. Anhand der Konversionsrate können Sie die Effektivität Ihrer Aufforderungen zum Handeln und die allgemeine Benutzerfreundlichkeit beurteilen.<br /> </li>
</ul>
<ul>
<li><strong>Seitenladegeschwindigkeit</strong>: Die Zeit, die Ihre Website benötigt, um im Browser eines Besuchers vollständig zu laden. Schnellere Ladezeiten stehen in Zusammenhang mit höherer Benutzerzufriedenheit und niedrigeren Absprungraten, so dass die Optimierung der Seitengeschwindigkeit für ein positives Benutzererlebnis unerlässlich ist.</li>
</ul>
<p><strong><em>Tools zur Messung</em></strong></p>
<p>Es gibt verschiedene Tools, mit denen Sie die Leistung Ihrer Website messen und analysieren können, z. B:<br /> </p>
<ul>
<li><strong>Google Analytics</strong>: Ein kostenloses Webanalyse-Tool, das wertvolle Einblicke in den Website-Verkehr, das Nutzerverhalten und die Leistungsmetriken bietet. Mit Google Analytics können Sie KPIs nachverfolgen, benutzerdefinierte Berichte einrichten und ein tieferes Verständnis für Ihr Publikum gewinnen.<br /> </li>
</ul>
<ul>
<li><strong>Heatmaps</strong>: Heatmap-Tools wie Crazy Egg oder Hotjar stellen die Interaktion der Nutzer mit Ihrer Website visuell dar und heben Bereiche mit hohem Engagement und Bereiche, die möglicherweise verbessert werden müssen, hervor. Mithilfe von Heatmaps können Sie feststellen, welche Elemente die Aufmerksamkeit auf sich ziehen und welche ignoriert werden.<br /> </li>
</ul>
<ul>
<li><strong>A/B-Tests</strong>: Beim A/B-Testing werden zwei Versionen einer Webseite miteinander verglichen, um festzustellen, welche Version in Bezug auf die Nutzerinteraktion und die Konversionsrate besser abschneidet. Durch das Testen verschiedener Designelemente, Layouts oder Handlungsaufforderungen können Sie feststellen, welche Varianten am effektivsten sind, und diese entsprechend anpassen.</li>
</ul>
<p><strong><em>Iteration für den Erfolg</em></strong></p>
<p>Sobald Sie Daten und Erkenntnisse aus Ihren Messinstrumenten gesammelt haben, ist es an der Zeit, Ihre Webdesign-Strategien zu iterieren, um die Leistung zu verbessern. Hier sind einige Tipps für eine effektive Iteration:<br /> </p>
<ul>
<li><strong>Identifizieren Sie verbesserungswürdige Bereiche</strong>: Analysieren Sie die Daten, um Trends, Muster und Schwachstellen in der Leistung Ihrer Website zu erkennen. Suchen Sie nach Möglichkeiten zur Verbesserung der Benutzerfreundlichkeit, zur Steigerung des Engagements und zur Förderung von Konversionen.<br /> </li>
</ul>
<ul>
<li><strong>Setzen Sie Prioritäten</strong>: Setzen Sie Prioritäten für die zu verbessernden Bereiche auf der Grundlage ihrer potenziellen Auswirkungen auf die Ziele Ihrer Website. Konzentrieren Sie sich zunächst auf die kritischsten Probleme, bevor Sie zu kleineren Optimierungen übergehen.<br /> </li>
</ul>
<ul>
<li><strong>Änderungen umsetzen</strong>: Nehmen Sie auf der Grundlage Ihrer Analysen und Erkenntnisse gezielte Änderungen am Design, am Inhalt oder an der Funktionalität Ihrer Website vor. Experimentieren Sie mit verschiedenen Ansätzen und beobachten Sie deren Auswirkungen auf Ihre KPIs.<br /> </li>
</ul>
<ul>
<li><strong>Ergebnisse überwachen</strong>: Überwachen Sie fortlaufend die Auswirkungen Ihrer Änderungen auf die Leistungskennzahlen Ihrer Website. Verfolgen Sie, wie sich die Änderungen auf die Absprungrate, die Verweildauer auf der Seite, die Konversionsrate und andere relevante KPIs auswirken, um ihre Wirksamkeit zu beurteilen.<br /> </li>
</ul>
<ul>
<li><strong>Erneut iterieren</strong>: Auf der Grundlage der Ergebnisse Ihrer Änderungen können Sie Ihre Webdesign-Strategien weiter verfeinern und die Optimierung für den Erfolg fortsetzen. Der iterative Prozess ermöglicht es Ihnen, Ihre Website im Laufe der Zeit schrittweise zu verbessern und sicherzustellen, dass sie in der sich ständig weiterentwickelnden digitalen Landschaft effektiv und wettbewerbsfähig bleibt.</li>
</ul>
<p>Im Grunde genommen ist das Messen und Wiederholen Ihrer Webdesign-Strategien also unerlässlich, um den Erfolg und die Effektivität Ihrer Website sicherzustellen. Durch die Festlegung von Leistungsindikatoren, die Verwendung von Messinstrumenten und die kontinuierliche Anpassung auf der Grundlage von Daten und Erkenntnissen können Sie Ihre Website für ein Höchstmaß an Engagement, Konversion und Nutzerzufriedenheit optimieren.</p>
<p><strong>Abschließende Überlegungen</strong></p>
<p>Zusammenfassend lässt sich sagen, dass es für den Erfolg Ihrer Website von entscheidender Bedeutung ist, die Aufmerksamkeit oberhalb und unterhalb des Falzes zu gewinnen. Durch die Umsetzung der in diesem Beitrag beschriebenen Strategien können Sie ein überzeugendes Nutzererlebnis schaffen, das die Besucher bei der Stange hält und sie zum Handeln anregt.</p>

Using Lighthouse, we can assess web pages based on overall performance, accessibility, SEO, and what Google considers “best practices”, all with the click of a button.
We might use these tests to evaluate out-of-the-box performance for front-end frameworks or to celebrate performance improvements gained by some diligent refactoring. And you know you love sharing screenshots of your perfect Lighthouse scores on social media. It’s a well-deserved badge of honor worthy of a confetti celebration.
Just the fact that Lighthouse gets developers like us talking about performance is a win. But, whilst I don’t want to be a party pooper, the truth is that web performance is far more nuanced than this. In this article, we’ll examine how Google Lighthouse calculates its performance scores, and, using this information, we will attempt to “hack” those scores in our favor, __all in the name of fun and science__ — because in the end, Lighthouse is simply a good, but rough guide for debugging performance. We’ll have some fun with it and see to what extent we can “trick” Lighthouse into handing out better scores than we may deserve.
But first, let’s talk about data.
## Field data is important
Local performance testing is a great way to understand if your website performance is trending in the right direction, but it won’t paint a full picture of reality. The World Wide Web is the Wild West, and collectively, we’ve almost certainly lost track of the variety of device types, internet connection speeds, screen sizes, browsers, and browser versions that people are using to access websites — all of which can have an impact on page performance and user experience.
Field data — and lots of it — collected by an [Application Performance Monitoring](http://sentry.io/for/performance/) tool like Sentry from real people using your website on their devices will give you a far more accurate report of your website performance than your lab data collected from a sample size of one using a high-spec super-powered dev machine under a set of controlled conditions. Philip Walton reported in 2021 that “[almost half of all pages that scored 100 on Lighthouse didn’t meet the recommended Core Web Vitals thresholds](https://philipwalton.com/articles/my-challenge-to-the-web-performance-community/)” based on data from the HTTP Archive.
Web performance is more than a single [core web vital metric](https://sentry.io/for/web-vitals/) or Lighthouse performance score. What we’re talking about goes way beyond the type of raw data we’re working with.
## Web performance is more than numbers
*Speed* is often the first thing that comes up when talking about web performance — just how long does a page take to load? This isn’t the worst thing to measure, but we must bear in mind that speed is probably influenced heavily by business KPIs and sales targets. Google [released a report in 2018](https://www.thinkwithgoogle.com/marketing-strategies/app-and-mobile/mobile-page-speed-new-industry-benchmarks/) suggesting that the probability of bounces increases by 32% if the page load time reaches higher than three seconds, and soars to 123% if the page load time reaches 10 seconds. So, we must conclude that converting more sales requires reducing bounce rates. And to reduce bounce rates, we must make our pages *load* faster.
But what does “load faster” even mean? At some point, we’re physically incapable of making a web page load any faster. Humans — and the servers that connect them — are spread around the globe, and modern internet infrastructure can only deliver so many bytes at a time.
The bottom line is that page load is not a single moment in time. In an article titled “[What is speed?](https://web.dev/articles/what-is-speed)” Google explains that a page load event is:
> an experience that no single metric can fully capture. There are multiple moments during the load experience that can affect whether a user perceives it as ‘fast’, and if you just focus solely on one, you might miss bad experiences that happen during the rest of the time.
The key word here is *experience*. Real web performance is less about *numbers* and *speed* than it is about *how we experience* page load and page usability as users. And this segues nicely into a discussion of how Google Lighthouse calculates performance scores. (It’s much less about pure speed than you might think.)
## How is the Google Lighthouse performance score calculated?
The Google Lighthouse performance score is calculated using a weighted combination of scores based on core web vital metrics (i.e., First Contentful Paint (FCP), Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS)) and other speed-related metrics (i.e., Speed Index (SI) and Total Blocking Time (TBT)) that are __observable throughout the page load timeline__.
This is [how the metrics are weighted](https://developer.chrome.com/docs/lighthouse/performance/performance-scoring/#weightings) in the overall score:
| Metric | Weighting (%) |
| ------------------------------ | ------------- |
| Total Blocking Time (TBT) | 30 |
| Cumulative Layout Shift (CLS) | 25 |
| Largest Contentful Paint (LCP) | 25 |
| First Contentful Paint (FCP) | 10 |
| Speed Index (SI) | 10 |
| | |
The weighting assigned to each score gives us insight into how Google prioritizes the different building blocks of a good user experience:
### 1. A web page should respond to user input
The highest weighted metric is __Total Blocking Time (TBT)__, a metric that looks at the total time after the __First Contentful Paint (FCP)__ to help indicate where the main thread may be blocked long enough to prevent speedy responses to user input. The main thread is considered “blocked” any time there’s a JavaScript task running on the main thread for more than 50ms. Minimizing TBT ensures that a web page responds to physical user input (e.g., key presses, mouse clicks, and so on).
### 2. A web page should load useful content with no unexpected visual shifts
The next most weighted Lighthouse metrics are __Largest Contentful Paint (LCP)__ and __Cumulative Layout Shift (CLS)__. LCP marks the point in the page load timeline when the page’s main content has *likely* loaded and is therefore *useful*.
At the point where the main content has likely loaded, you also want to maintain visual stability to ensure that users can use the page and are not affected by unexpected visual shifts (CLS). A good LCP score is anything less than 2.5 seconds (which is a lot higher than we might have thought, given we are often trying to make our websites *as fast as possible*).
### 3. A web page should load something
The __First Contentful Paint (FCP)__ metric marks the first point in the page load timeline where the user can see something on the screen, and the __Speed Index (SI)__ measures how quickly content is visually displayed during page load over time until the page is “complete”.
Your page is scored based on the speed indices of real websites using performance [data from the HTTP Archive](https://developer.chrome.com/docs/lighthouse/performance/performance-scoring#metric-scores). A good FCP score is less than 1.8 seconds and a good SI score is less than 3.4 seconds. Both of these thresholds are higher than you might expect when thinking about speed.
## Usability is favored over raw speed
Google Lighthouse’s performance scoring is, without a doubt, less about speed and more about __usability__. Your SI and FCP could be super quick, but if your LCP takes too long to paint, and if CLS is caused by large images or external content taking some time to load and shifting things visually, then your overall performance score will be lower than if your page was a little slower to render the FCP but didn’t cause any CLS. Ultimately, if the page is unresponsive due to JavaScript blocking the main thread for more than 50ms, your performance score will suffer more than if the page was a little slow to paint the FCP.
To understand more about how the weightings of each metric contribute to the final performance score, you can play about with the sliders on the [Lighthouse Scoring Calculator](https://googlechrome.github.io/lighthouse/scorecalc/), and here’s a rudimentary table demonstrating the effect of skewed individual metric weightings on the overall performance score, proving that page usability and responsiveness is favored over raw speed.
| Description | FCP (ms) | SI (ms) | LCP (ms) | TBT (ms) | CLS | LH perf Score |
| ---------- | ---------- | ---------- | ---------- | ---------- | ---------- | ---------- |
| Slow to show something on screen | 6000 | 0 | 0 | 0 | 0 | 90 |
| Slow to load content over time | 0 | 5000 | 0 | 0 | 0 | 90 |
| Slow to load the largest part of the page | 0 | 0 | 6000 | 0 | 0 | 76 |
| Visual shifts occurring during page load | 0 | 0 | 0 | 0 | 0.82 | 76 |

The overall Google Lighthouse performance score is calculated by converting each raw metric value into a score from 0 to 100 according to where it falls on its Lighthouse scoring distribution, which is a __log-normal__ distribution derived from the performance metrics of real website performance data from the HTTP Archive. There are two main takeaways from this mathematically overloaded information:
1. Your Lighthouse performance score is plotted against real website performance data, not in isolation.
1. Given that the scoring uses log-normal distribution, the relationship between the individual metric values and the overall score is non-linear, meaning you can make substantial improvements to low-performance scores quite easily, but it becomes more difficult to improve an already high score.
Read more about [how metric scores are determined](https://developer.chrome.com/docs/lighthouse/performance/performance-scoring#metric-scores), including a visualization of the log-normal distribution curve on [developer.chrome.com](http://developer.chrome.com).
## Can we "trick" Google Lighthouse?
I appreciate Google’s focus on usability over pure speed in the web performance conversation. It urges developers to think less about aiming for raw numbers and more about the real experiences we build. That being said, I’ve wondered whether today in 2024, it’s possible to fool Google Lighthouse into believing that a bad page in terms of usability and usefulness is actually a great one.
I put on my lab coat and science goggles to investigate. All tests were conducted:
- Using the Chromium Lighthouse plugin,
- In an incognito window in the Arc browser,
- Using the “navigation” and “mobile” settings (apart from where described differently),
- By me, in a lab (i.e., no field data).
That all being said, I fully acknowledge that my controlled test environment contradicts my advice at the top of this post, but the experiment is an interesting ride nonetheless. What I hope you’ll take away from this is that Lighthouse scores are only one piece — and a tiny one at that — of a very large and complex web performance puzzle. And, without field data, I’m not sure any of this matters anyway.
## How to hack FCP and LCP scores
---
__TL;DR: show the smallest amount of LCP-qualifying content on load to boost the FCP and LCP scores until the Lighthouse test has likely finished.__
---
FCP marks the first point in the page load timeline where the user can see anything at all on the screen, while LCP marks the point in the page load timeline when the main page content (i.e., the largest text or image element) has likely loaded. A fast LCP helps reassure the user that the page is *useful*. “Likely” and “useful” are the important words to bear in mind here.
### What counts as an LCP element
The types of elements on a web page considered by Lighthouse for LCP are:
- `<img>` elements
- `<image>` elements inside an `<svg>` element
- `<video>` elements
- An element with a background image loaded using the `url()` function, (and not a CSS gradient)
- Block-level elements containing text nodes or other inline-level text elements
The following elements are *excluded* from LCP consideration due to the likelihood they do not contain useful content:
- Elements with zero opacity (invisible to the user),
- Elements that cover the full viewport (likely to be background elements), and
- Placeholder images or other images with low entropy (i.e., low informational content, such as a solid-colored image).
However, the notion of an image or text element being useful is completely subjective in this case and generally out of the realm of what machine code can reliably determine. For example, [I built a page](https://hacking-lighthouse.netlify.app/lcp/) containing nothing but a `<h1>` element where, after 10 seconds, JavaScript inserts more descriptive text into the DOM and hides the `<h1>` element.
Lighthouse considers the heading element to be the LCP element in this experiment. At this point, the page load timeline has finished, but the page’s main content has not loaded, even though Lighthouse thinks it is *likely* to have loaded within those 10 seconds. Lighthouse still awards us with a perfect score of 100 even if the heading is replaced by a single punctuation mark, such as a full stop, which is even less *useful*.
This test suggests that if you need to load page content via client-side JavaScript, we‘ll want to avoid displaying a skeleton loader screen since that requires loading more elements on the page. And since we know the process will take some time — and that we can offload the network request from the main thread to a web worker so it won’t affect the TBT — we can use some arbitrary “splash screen” that contains a minimal viable LCP element (for better FCP scoring). This way, we’re giving Lighthouse the impression that the page is useful to users quicker than it actually is.
All we need to do is include a valid LCP element that contains something that counts as the FCP. While I would never recommend loading your main page content via client-side JavaScript in 2024 (serve static HTML from a CDN instead or build as much of the page as you can on a server), I would definitely not recommend this “hack” for a good user experience, regardless of what the Lighthouse performance score tells you. This approach also won’t earn you any favors with search engines indexing your site, as the robots are unable to discover the main content while it is absent from the DOM.
I also tried this experiment with a variety of random images representing the LCP to make the page even less useful. But given that I used small file sizes — made smaller and converted into “next-gen” image formats using a third-party image API to help with page load speed — it seemed that Lighthouse interpreted the elements as “placeholder images” or images with “low entropy”. As a result, those images were disqualified as LCP elements, which is a good thing and makes the LCP slightly less hackable.
View [the demo page](https://hacking-lighthouse.netlify.app/lcp/) and use Chromium DevTools in an incognito window to see the results yourself.
This hack, however, probably won’t hold up in many other use cases. Discord, for example, uses the “splash screen” approach when you hard-refresh the app in the browser, and it receives a sad 29 performance score.
Compared to my DOM-injected demo, the LCP element was calculated as some content behind the splash screen rather than elements contained within the splash screen content itself, given there were one or more large images in the focussed text channel I tested on. One could argue that Lighthouse scores are less important for apps that are behind authentication anyway: they don’t need to be indexed by search engines.
There are likely many other situations where apps serve user-generated content and you might be unable to control the LCP element entirely, particularly regarding images.
For example, if you can control the sizes of all the images on your web pages, you might be able to take advantage of an interesting hack or “optimization” (in very large quotes) to arbitrarily game the system, as was the case of RentPath. In 2021, developers at RentPath managed to [improve their Lighthouse performance score by 17 points](https://blog.rentpathcode.com/we-increased-our-lighthouse-score-by-17-points-by-making-our-images-larger-83f60b33a942) when increasing the size of image thumbnails on a web page. They convinced Lighthouse to calculate the LCP element as one of the larger thumbnails instead of a Google Map tile on the page, which takes considerably longer to load via JavaScript.
The bottom line is that you can gain higher Lighthouse performance scores if you are aware of your LCP element and in control of it, whether that’s through a hack like RentPath’s or mine or a real-deal improvement. That being said, whilst I’ve described the splash screen approach as a hack in this post, that doesn’t mean this type of experience couldn’t offer a purposeful and joyful experience. Performance and user experience are about understanding what’s happening during page load, and it’s also about intent.
## How to hack CLS scores
---
__TL;DR: defer loading content that will cause layout shifts until the Lighthouse test has likely finished because it thinks it has enough data. CSS animations using transform won’t cause CLS, except if used in conjunction with adding new elements to the DOM.__
---
CLS is measured on a decimal scale; a good score is less than 0.1, and a poor score is greater than 0.25. Lighthouse calculates CLS from the largest burst of unexpected layout shifts that occur during a user’s time on the page based on a combination of the viewport size and the movement of unstable elements in the viewport between two rendered frames. Smaller one-off instances of layout shift may be inconsequential, but a bunch of layout shifts happening one after the other will negatively impact your score.
If you know your page contains annoying layout shifts on load, you can defer them until after the page load event has been completed, thus fooling Lighthouse into thinking there is no CLS. [This demo page I created](https://hacking-lighthouse.netlify.app/cls-bad/), for example, earns a CLS score of 0.143 even though JavaScript immediately starts adding new text elements to the page, shifting the original content up. By pausing the JavaScript that adds new nodes to the DOM by an arbitrary five seconds with a `setTimeout()`, Lighthouse doesn’t capture the CLS that takes place.
[This other demo page](https://hacking-lighthouse.netlify.app/cls-hacked/) earns a performance score of 100, even though it is arguably less useful and useable than the last page given that the added elements pop in seemingly at random without any user interaction.
Whilst it is possible to defer layout shift events for a page load test, this hack definitely won’t work for field data and user experience over time (which is a more important focal point, as we discussed earlier). If we perform a “time span” test in Lighthouse on the page with deferred layout shifts, Lighthouse will correctly report a non-green CLS score of around 0.186.
If you do want to intentionally create a chaotic experience similar to the demo, you can use CSS animations and transforms to more purposefully pop the content into view on the page. In [Google’s guide to CLS](https://web.dev/articles/cls), they state that “content that moves gradually and naturally from one position to another can often help the user better understand what’s going on and guide them between state changes” — again, highlighting the importance of user experience in context.
On [this next demo page](https://hacking-lighthouse.netlify.app/cls-animated/), I’m using CSS `transform` to `scale()` the text elements from `0` to `1` and move them around the page. The transforms fail to trigger CLS because the text nodes are already in the DOM when the page loads. That said, I did observe in my testing that if the text nodes are added to the DOM programmatically after the page loads via JavaScript and then animated, Lighthouse will indeed detect CLS and score things accordingly.
## You can’t hack a Speed Index score
The Speed Index score is based on the visual progress of the page as it loads. The quicker your content loads nearer the beginning of the page load timeline, the better.
It is possible to do some hack to trick the Speed Index into thinking a page load timeline is slower than it is. Conversely, there’s no real way to “fake” loading content faster than it does. The only way to make your Speed Index score better is to optimize your web page for loading as much of the page as possible, as soon as possible. Whilst not entirely realistic in the web landscape of 2024 (mainly because it would put designers out of a job), you could go all-in to lower your Speed Index as much as possible by:
- Delivering static HTML web pages only (no server-side rendering) straight from a CDN,
- Avoiding images on the page,
- Minimizing or eliminating CSS, and
- Preventing JavaScript or any external dependencies from loading.
## You also can’t (really) hack a TBT score
TBT measures the total time after the FCP where the main thread was blocked by JavaScript tasks for long enough to prevent responses to user input. A good TBT score is anything lower than 200ms.
JavaScript-heavy web applications (such as single-page applications) that perform complex state calculations and DOM manipulation on the client on page load (rather than on the server before sending rendered HTML) are prone to suffering poor TBT scores. In this case, you could probably hack your TBT score by deferring all JavaScript until after the Lighthouse test has finished. That said, you’d need to provide some kind of placeholder content or loading screen to satisfy the FCP and LCP and to inform users that something will happen *at some point*. Plus, you’d have to go to extra lengths to hack around the front-end framework you’re using. (You don’t want to load a placeholder page that, at some point in the page load timeline, loads a separate React app after an arbitrary amount of time!)
What’s interesting is that while we’re still doing all sorts of fancy things with JavaScript in the client, advances in the modern web ecosystem are helping us all reduce the probability of a less-than-stellar TBT score. Many front-end frameworks, in partnership with modern hosting providers, are capable of rendering pages and processing complex logic on demand without any client-side JavaScript. While eliminating JavaScript on the client is not the goal, we certainly have a lot of options to use a lot *less* of it, thus minimizing the risk of doing too much computation on the main thread on page load.
## Bottom line: Lighthouse is still just a rough guide
Google Lighthouse can’t detect everything that’s wrong with a particular website. Whilst Lighthouse performance scores prioritize page usability in terms of responding to user input, it still can’t detect every terrible usability or accessibility issue in 2024.
In 2019, Manuel Matuzović [published an experiment](https://www.matuzo.at/blog/building-the-most-inaccessible-site-possible-with-a-perfect-lighthouse-score/) where he intentionally created a terrible page that Lighthouse thought was pretty great. I hypothesized that five years later, Lighthouse might do better; but it doesn’t.
On this final [demo page](https://hacking-lighthouse.netlify.app/unusable/) I put together, input events are disabled by CSS and JavaScript, making the page technically unresponsive to user input. After five seconds, JavaScript flips a switch and allows you to click the button. The page still scores 100 for both performance and accessibility.
You really can’t rely on Lighthouse as a substitute for usability testing and common sense.
## Some more silly hacks
As with everything in life, there’s always a way to game the system. Here are some more tried and tested guaranteed hacks to make sure your Lighthouse performance score artificially knocks everyone else’s out of the park:
- Only run Lighthouse tests using the fastest and highest-spec hardware.
- Make sure your internet connection is the fastest it can be; relocate if you need to.
- Never use field data, only lab data, collected using the aforementioned fastest and highest-spec hardware and super-speed internet connection.
- Rerun the tests in the lab using different conditions and all the special code hacks I described in this post until you get the result(s) you want to impress your friends, colleagues, and random people on the internet.
__Note__: *The best way to learn about web performance and how to optimize your websites is to do the complete opposite of everything we’ve covered in this article all of the time. And finally, to seriously level up your performance skills, [use an application monitoring tool like Sentry](https://sentry.io/for/performance/?utm_source=smashingmag&utm_medium=paid-community&utm_campaign=perf-fy25q2-evergreen&utm_content=blog-lighthouseblog-signup). Think of Lighthouse as the canary and Sentry as the real-deal production-data-capturing, lean, mean, [web vitals](https://docs.sentry.io/product/performance/web-vitals/?utm_source=smashingmag&utm_medium=paid-community&utm_campaign=perf-fy25q2-evergreen&utm_content=blog-lighthouseblog-signup) machine.*

I ended up writing a simple Python script that allows you to get the current value in the clipboard, clear it, and get its history via the command line interface (CLI).
---
## How it Works
Here is a step-by-step guide to implementing this functionality:
- **Define a ClipboardManager class**:
The first step is to define a `ClipboardManager` class. This class will serve as the foundation for managing clipboard operations within the script. The `__init__` method is the constructor: it sets up the initial state of the object when it is created. In this example, `__init__` initializes `history` as an empty list and `current_value` as None.
```python
class ClipboardManager:
def __init__(self):
self.history = []
self.current_value = None
```
- **Implement get clipboard and clear clipboard methods**:
Using the [pyperclip](https://pypi.org/project/pyperclip/) module, we define methods within the `ClipboardManager` class to interact with the clipboard. These methods allow fetching the current clipboard value and clearing the clipboard. Every time we get the current clipboard value, we add it in the history list to keep track of it.
```python
def get_clipboard(self):
value = pyperclip.paste()
if value != self.current_value:
self.history.append(value)
self.current_value = value
return value
def clear_clipboard(self):
pyperclip.copy('')
self.current_value = ''
print("Clipboard cleared.")
```
- **Implement the show history method**:
Next, we need to include a method that displays the history of clipboard values stored in `self.history`. In this method, we loop through the items in the list and use the [enumerate built-in function](https://docs.python.org/3/library/functions.html#enumerate) to pair each value with an index, producing a numbered list. We set the starting index to 1 to make the output more user-friendly, aligning with the human convention of counting from 1, unlike computers which typically start counting from 0.
```python
def show_history(self):
if self.history:
for idx, value in enumerate(self.history, start=1):
print(f"{idx}: {value}")
else:
print("No history available.")
```
- **Instantiate the class and provide options in the CLI**:
The last step is to implement the main execution logic of the script. We instantiate an object of `ClipboardManager` and create a user-friendly menu in the command-line interface to allow users to perform operations on the clipboard.
```python
if __name__ == "__main__":
manager = ClipboardManager()
while True:
print("\nMenu:")
print("1. Get current clipboard value")
print("2. Show clipboard history")
print("3. Clear clipboard")
print("4. Exit")
choice = input("Enter your choice (1-4): ")
if choice == '1':
current_value = manager.get_clipboard()
print(f"Current clipboard value: {current_value}")
elif choice == '2':
manager.show_history()
elif choice == '3':
manager.clear_clipboard()
elif choice == '4':
print("Exiting...")
break
else:
print("Invalid choice. Please enter a number from 1 to 4.")
```
This is the final script:
```python
import pyperclip
class ClipboardManager:
def __init__(self):
self.history = []
self.current_value = None
def get_clipboard(self):
value = pyperclip.paste()
if value != self.current_value:
self.history.append(value)
self.current_value = value
return value
def show_history(self):
if self.history:
for idx, value in enumerate(self.history, start=1):
print(f"{idx}: {value}")
else:
print("No history available.")
def clear_clipboard(self):
pyperclip.copy('')
self.current_value = ''
print("Clipboard cleared.")
if __name__ == "__main__":
manager = ClipboardManager()
while True:
print("\nMenu:")
print("1. Get current clipboard value")
print("2. Show clipboard history")
print("3. Clear clipboard")
print("4. Exit")
choice = input("Enter your choice (1-4): ")
if choice == '1':
current_value = manager.get_clipboard()
print(f"Current clipboard value: {current_value}")
elif choice == '2':
manager.show_history()
elif choice == '3':
manager.clear_clipboard()
elif choice == '4':
print("Exiting...")
break
else:
print("Invalid choice. Please enter a number from 1 to 4.")
```
## Usage
To utilize this script, follow these steps:
- Save the script into a file with a .py extension (e.g., clipboard-script.py).
- Open a terminal and navigate to the directory containing the script.
- Run the script by providing the script path. For example:
```bash
python3 <script-path>
```
```bash
python3 clipboard-script.py
```
Now, you can test the script by copying text from your command-line interface (CLI) and begin utilizing its functionality to manage clipboard operations effectively.✨

The Titanic dataset, available on Kaggle, contains detailed information about the passengers aboard the ill-fated RMS Titanic. This dataset is a popular choice for data analysis and machine learning practice due to its rich variety of numerical and categorical variables. The purpose of this review is to conduct an initial exploration of the dataset, identifying key insights and patterns at first glance.
**Observations**
Upon examining the Titanic dataset, several initial observations can be made:
**Survival Rate: **The dataset includes a Survived column, where 0 indicates the passenger did not survive, and 1 indicates survival. A quick count of this column shows that a minority of passengers survived the disaster. Specifically, only about 38% of the passengers survived, highlighting the tragedy's severity.
`# Basic survival rate calculation
survival_rate = df['Survived'].mean()`
**Passenger Class Distribution:** The dataset contains a Pclass column indicating the class of travel (1st, 2nd, or 3rd class). A review shows that the majority of passengers were in the 3rd class, followed by 1st and then 2nd class. This distribution suggests a diverse socio-economic background among the passengers.
```
# Distribution of passenger classes
class_distribution = df['Pclass'].value_counts()
```
**Age Distribution: ** The Age column reveals the age distribution of the passengers. The dataset includes a range of ages from infants to elderly passengers. A histogram of the ages shows a concentration of passengers in their 20s and 30s, with fewer children and older adults. There are also some missing values in the Age column, which could impact further analysis.
```
# Basic age distribution and missing values
age_distribution = df['Age'].describe()
missing_age_values = df['Age'].isnull().sum()
```
**Visualization**
To support these observations, a simple visualization of the age distribution can be helpful. Below is a histogram depicting the age distribution of the passengers.
```
import matplotlib.pyplot as plt
import seaborn as sns
# Loading the Titanic dataset
df = sns.load_dataset('titanic')
# Histogram of passenger ages
plt.hist(df['Age'].dropna(), bins=30, edgecolor='black')
plt.title('Age Distribution of Titanic Passengers')
plt.xlabel('Age')
plt.ylabel('Frequency')
plt.show()
```
**The image output will be **
**Conclusion**
In summary, the Titanic dataset reveals several initial insights:
- The survival rate among passengers was low, with only about 38% surviving.
- The majority of passengers traveled in the 3rd class, indicating a varied socio-economic passenger base.
- The age distribution shows a concentration of passengers in their 20s and 30s, with some missing age data that could be addressed in further analysis.
These observations provide a foundation for more in-depth exploration and analysis. Future steps could include examining the impact of different variables on survival rates, filling missing age values using predictive modeling, and exploring relationships between other variables such as fare, gender, and passenger class.

In today’s fast-paced job market, the integration of artificial intelligence (AI) in recruitment is not just a trend but a necessity. A [recent study](https://blog.namely.com/how-ai-is-transforming-talent-acquisition-strategies) revealed that 58% of hiring managers and recruiters say AI has made their jobs easier, with 56% predicting that AI will continue to revolutionize the recruitment process. As companies strive to fill [top IT jobs in Germany](https://www.tech-careers.de/) and other competitive markets, the deployment of AI tools like ChatGPT is transforming how organizations find and engage talent.
**What is ChatGPT?**
ChatGPT, developed by OpenAI, is an advanced language model that uses machine learning to understand and generate human-like text. Trained on a diverse range of internet text, ChatGPT can perform a variety of tasks, from answering questions to conducting conversations. In the context of ChatGPT in recruitment, it can automate numerous tasks, making the hiring process more efficient and effective.
## Applications of ChatGPT in Recruitment

1,907,303 | Exploring the World of Testing: Automated vs Manual | Testing is like the superhero of the software world – it ensures everything works smoothly and saves... | 0 | 2024-07-01T07:31:41 | https://www.thetealmango.com/featured/automated-vs-manual-testing/ | automated, testing, manual | 
Testing is like the superhero of the software world – it ensures everything works smoothly and saves the day. But did you know there are different ways to do it? Let’s dive into the two main types: automated testing vs manual testing.
**Automated Testing: The Tech Wizard**
Imagine a robot doing your homework – that’s automated testing. It’s like having a computer run through your software to check if everything is in order. This is super handy when you have a lot of tasks and want them done fast and accurately.
**Pros of Automated Testing**:
**Speedy Gonzalez**: Computers are lightning fast. They can run tests way quicker than a human could click through every button.
**Repetition Friendly**: If you have to test the same things over and over, why not let a computer handle it? They don’t get bored or tired.
**Accuracy Squad**: Computers follow instructions in the letter. No typos, no mistakes – they’re like the superheroes of precision.
Cons of Automated Testing
**Not for Everything**: Some things are just better checked by a human with a keen eye. Automated testing might miss out on the “human touch.”
Set-up Time: It takes a bit of time to set up the automated tests initially. Once they’re ready, though, it’s smooth sailing.
**Manual Testing: The Hands-On Hero**
Now, picture yourself going through a treasure map with your own hands. That’s manual testing. You’re the detective, exploring every nook and cranny to make sure everything is as it should be.
**Pros of Manual Testing**:
**Adaptability**: Humans are great at adapting to changes. If something unexpected comes up, a tester can handle it on the spot.
**User Experience Experts**: Testing isn’t just about functionality; it’s also about how easy and enjoyable it is for users. Humans can sense that better than robots.
**Exploration Mode**: Manual testing allows for exploration. Testers can find unexpected issues that automated tests might overlook.
**Cons of Manual Testing**:
**Snail’s Pace**: Compared to automated testing, manual testing can be slower. Humans can’t click as fast as computers.
**Human Error Risk**: We’re not perfect. Humans might make mistakes – click the wrong button, miss a tiny bug, or forget a step.
ERP testing tools are crucial for ensuring the smooth operation of integrated business systems. With a focus on ERP testing tools, organizations can leverage solutions like SAP Test Acceleration and Oracle Application Testing Suite to automate processes, reduce manual effort, and guarantee the robustness of their ERP implementations. These tools, driven by keyword-driven testing approaches, empower businesses to conduct comprehensive testing, leading to enhanced efficiency and reliability in their ERP ecosystems.
**Finding the Right Balance**
So, who wins in the battle of Automated Testing vs. Manual Testing? Well, it’s not really a battle. Both have their strengths and weaknesses. The trick is finding the right balance.
Imagine a superhero team where computers and humans work together. Automated testing can handle repetitive tasks, leaving humans to do what they do best – adapt, explore, and make sure everything feels just right for the users.
In the end, it’s not about choosing one over the other; it’s about combining their powers to create a testing dream team. And together, they ensure the software world stays safe and sound. | rohitbhandari102 |

Signed drivers are the main actors who guarantee the system’s safety and stability by permitting only trusted and verified software components to communicate with the kernel.
Signing a driver is a process of validation where the developer’s identity is confirmed, and the construction of the driver code is verified. This procedure is communally pursued by a certificate authority (CA) or any trusted third-party website.
After the driver is verified, a digital certificate is issued to the driver, which contains the developer’s information and the cryptographic hash of the driver file. A digital signature is embedded in the driver file itself.
Using signed drivers by operating systems like Windows, macOS, and Linux is one security measure to prevent unauthorized access to the software.

1,907,290 | How to Annul Promises in JavaScript | In JavaScript, you might already know how to cancel a request: you can use xhr.abort() for XHR and... | 0 | 2024-07-01T07:26:16 | https://webdeveloper.beehiiv.com/p/cancel-promises-javascript | webdev, react, javascript, programming | In JavaScript, you might already know [how to cancel a request](https://levelup.gitconnected.com/how-to-cancel-a-request-in-javascript-67f98bd1f0f5?utm_source=webdeveloper.beehiiv.com&utm_medium=newsletter&utm_campaign=how-to-annul-promises-in-javascript): you can use `xhr.abort()` for XHR and `signal` for fetch. But how do you cancel a regular Promise?
Currently, JavaScript's Promise does not natively provide an API to cancel a regular Promise. **So, what we’ll discuss next is how to discard/ignore the result of a Promise.**
## **Method 1: Using the New Promise.withResolvers()**
A new API that can now be used is [Promise.withResolvers()](https://levelup.gitconnected.com/new-async-api-promise-withresolvers-simplifies-your-code-1355784fb435?utm_source=webdeveloper.beehiiv.com&utm_medium=newsletter&utm_campaign=how-to-annul-promises-in-javascript). It returns an object containing a new Promise object and two functions to resolve or reject it.
Here’s how the code looks:
```javascript
let resolve, reject;
const promise = new Promise((res, rej) => {
resolve = res;
reject = rej;
});
```
Now we can do this:
```typescript
const { promise, resolve, reject } = Promise.withResolvers();
```
So we can utilize this to expose a `cancel` method:
```typescript
const buildCancelableTask = <T>(asyncFn: () => Promise<T>) => {
let rejected = false;
const { promise, resolve, reject } = Promise.withResolvers<T>();
return {
run: () => {
if (!rejected) {
asyncFn().then(resolve, reject);
}
return promise;
},
cancel: () => {
rejected = true;
reject(new Error('CanceledError'));
},
};
};
```
Then we can use it with the following test code:
```typescript
const sleep = (ms: number) => new Promise(res => setTimeout(res, ms));
const ret = buildCancelableTask(async () => {
await sleep(1000);
return 'Hello';
});
(async () => {
try {
const val = await ret.run();
console.log('val: ', val);
} catch (err) {
console.log('err: ', err);
}
})();
setTimeout(() => {
ret.cancel();
}, 500);
```
Here, we preset the task to take at least 1000ms, but we cancel it within the next 500ms, so you will see:
Note that this is not true cancellation but an early rejection. The original `asyncFn()` will continue to execute until it resolves or rejects, but it doesn’t matter because the promise created with `Promise.withResolvers<T>()` has already been rejected.
## Method 2: Using AbortController
Just like we cancel fetch requests, we can implement a listener to achieve early rejection. It looks like this:
```typescript
const buildCancelableTask = <T>(asyncFn: () => Promise<T>) => {
const abortController = new AbortController();
return {
run: () =>
new Promise<T>((resolve, reject) => {
const cancelTask = () => reject(new Error('CanceledError'));
if (abortController.signal.aborted) {
cancelTask();
return;
}
asyncFn().then(resolve, reject);
abortController.signal.addEventListener('abort', cancelTask);
}),
cancel: () => {
abortController.abort();
},
};
};
```
It has the same effect as mentioned above but uses AbortController. You can use other listeners here, but AbortController provides the additional benefit that if you call `cancel` multiple times, it won’t trigger the `'abort'` event more than once.
Based on this code, we can go further to build a cancelable fetch. This can be useful in scenarios like sequential requests, where you might want to discard previous request results and use the latest request results.
```typescript
const buildCancelableFetch = <T>(
requestFn: (signal: AbortSignal) => Promise<T>,
) => {
const abortController = new AbortController();
return {
run: () =>
new Promise<T>((resolve, reject) => {
if (abortController.signal.aborted) {
reject(new Error('CanceledError'));
return;
}
requestFn(abortController.signal).then(resolve, reject);
}),
cancel: () => {
abortController.abort();
},
};
};
const ret = buildCancelableFetch(async signal => {
return fetch('http://localhost:5000', { signal }).then(res =>
res.text(),
);
});
(async () => {
try {
const val = await ret.run();
console.log('val: ', val);
} catch (err) {
console.log('err: ', err);
}
})();
setTimeout(() => {
ret.cancel();
}, 500);
```
Please note that this does not affect the server-side processing logic; it merely causes the browser to discard/cancel the request. In other words, if you send a POST request to update user information, it may still take effect. Therefore, this is more commonly used in scenarios where a GET request is made to fetch new data.
### Building a Simple Sequential Request React Hook
We can further encapsulate a simple sequential request React hook:
```typescript
import { useCallback, useRef } from 'react';
type RequestFn<T> = (signal: AbortSignal) => Promise<T>;
const buildCancelableFetch = <T>(
requestFn: (signal: AbortSignal) => Promise<T>,
) => {
const abortController = new AbortController();
return {
run: () =>
new Promise<T>((resolve, reject) => {
if (abortController.signal.aborted) {
reject(new Error('CanceledError'));
return;
}
requestFn(abortController.signal).then(resolve, reject);
}),
cancel: () => {
abortController.abort();
},
};
};
function useLatest<T>(value: T) {
const ref = useRef(value);
ref.current = value;
return ref;
}
export function useSequentialRequest<T>(requestFn: RequestFn<T>) {
const requestFnRef = useLatest(requestFn);
const currentRequest = useRef<{ cancel: () => void } | null>(null);
return useCallback(() => {
if (currentRequest.current) {
currentRequest.current.cancel();
}
const { run, cancel } = buildCancelableFetch(
requestFnRef.current,
);
currentRequest.current = { cancel };
const promise = run().then(res => {
currentRequest.current = null;
return res;
});
return promise;
}, [requestFnRef]);
}
```
Then we can simply use it:
```typescript
import { useSequentialRequest } from './useSequentialRequest';
export function App() {
const run = useSequentialRequest(async (signal: AbortSignal) => {
const ret = await fetch('http://localhost:5000', { signal }).then(
res => res.text(),
);
console.log(ret);
});
return (
<button onClick={run}>Run</button>
);
}
```
This way, when you click the button multiple times quickly, you will only get the latest request data, discarding the previous requests.

La Inteligencia Artificial (IA) ha revolucionado muchos campos, y la visión por computadora es una de las áreas donde su impacto es más pronunciado. Sin embargo, como con cualquier tecnología, el desarrollo y la implementación de sistemas de IA no están libres de sesgos y limitaciones. Este artículo profundiza en los matices del sesgo cultural en los sistemas de visión por computadora impulsados por IA, basándose en hallazgos recientes para destacar los desafíos y proponer posibles soluciones.
**Introducción**
La visión por computadora, una subdisciplina de la IA, permite a las máquinas interpretar y tomar decisiones basadas en datos visuales. Esta tecnología impulsa aplicaciones que van desde el reconocimiento facial y la conducción autónoma hasta la imagen médica y la realidad aumentada. Sin embargo, un problema crítico que ha surgido es el sesgo cultural inherente en muchos de estos sistemas de IA.
El sesgo cultural en la IA se refiere a la tendencia de los modelos de IA a rendir mejor con datos de ciertas culturas sobre otras. Este sesgo puede llevar a disparidades significativas en el rendimiento y la fiabilidad de las aplicaciones de IA en diferentes grupos demográficos. En el contexto de la visión por computadora, este sesgo se manifiesta de diversas maneras, incluyendo el reconocimiento de objetos, la detección de emociones y la comprensión de escenas.
El Estudio del Sesgo Cultural en los Modelos de Visión-Lenguaje
Investigaciones recientes, como el estudio titulado "See It from My Perspective: Diagnosing the Western Cultural Bias of Large Vision-Language Models in Image Understanding," proporcionan un análisis exhaustivo de cómo los modelos de visión-lenguaje actuales (VLMs) exhiben un sesgo cultural occidental. Estos modelos, que combinan datos visuales con capacidades de procesamiento del lenguaje, se utilizan cada vez más en diversas aplicaciones pero a menudo no representan con precisión las culturas no occidentales.
**Principales Hallazgos:
Disparidades en el Rendimiento:**
VLMs tienden a rendir mejor en imágenes y anotaciones de culturas occidentales en comparación con las orientales. Esta disparidad es evidente tanto en tareas objetivas (como la identificación de objetos) como en tareas subjetivas (como la clasificación de emociones en el arte).
Influencia del Preentrenamiento del Idioma:
La mezcla de idiomas utilizada durante la fase de preentrenamiento de estos modelos afecta significativamente su rendimiento. Los modelos preentrenados con una mezcla más equilibrada de idiomas, incluyendo el chino, muestran una reducción del sesgo occidental.
Impacto del Idioma de Consulta:
Consultar a estos modelos en el idioma de la cultura objetivo (por ejemplo, chino para culturas orientales) puede reducir el sesgo. Sin embargo, la reducción es más significativa cuando el idioma estaba bien representado durante el preentrenamiento.
Abordando el Sesgo Cultural en la Visión por Computadora
Para construir sistemas de IA más equitativos y representativos, es crucial abordar los sesgos culturales inherentes en los modelos actuales. Aquí hay algunas estrategias para mitigar estos sesgos:
**Datos de Entrenamiento Diversos:**
Asegurar que los conjuntos de datos de entrenamiento incluyan una amplia gama de imágenes y anotaciones de diversas culturas. Esta diversidad ayuda a los modelos a aprender representaciones más equilibradas.
Preentrenamiento Multilingüe:
Incorporar una mezcla equilibrada de idiomas durante la fase de preentrenamiento de los modelos de visión-lenguaje. Este enfoque ayuda a los modelos a desarrollar una comprensión más amplia de diferentes contextos culturales.
Ajuste Fino Específico de la Cultura:
Ajustar los modelos utilizando conjuntos de datos y anotaciones específicos de la cultura. Este paso puede ayudar a los modelos a adaptarse mejor a los matices de diferentes culturas.
Evaluación Transcultural:
Evaluar regularmente los modelos utilizando benchmarks culturalmente diversos. Esta evaluación ayuda a identificar y abordar las disparidades en el rendimiento desde las primeras etapas del proceso de desarrollo.
Incorporación de Contextos Culturales en el Diseño:
Diseñar sistemas de IA con los contextos culturales en mente. Este enfoque implica comprender cómo diferentes culturas perciben e interpretan los datos visuales e integrar esta comprensión en el diseño del modelo.
**Conclusión**
A medida que la IA continúa avanzando, es imperativo garantizar que estas tecnologías sean inclusivas y justas. Abordar el sesgo cultural en la visión por computadora no es solo un desafío técnico sino también un imperativo moral y ético. Al adoptar estrategias como datos de entrenamiento diversos, preentrenamiento multilingüe y ajuste fino específico de la cultura, podemos desarrollar sistemas de IA que sean más representativos y equitativos.
El camino hacia una IA sin sesgos está en curso y requiere un esfuerzo concertado de investigadores, desarrolladores y responsables de políticas. Al reconocer y abordar los sesgos culturales en la IA, podemos aprovechar todo el potencial de estas tecnologías en beneficio de todos.

Mobile App testing is the process of validating mobile Apps... | 0 | 2024-07-01T07:25:13 | https://dev.to/robort_smith/why-is-testing-important-for-your-mobile-app-2l9i | mobileapptesting, testing, mobile, software |
## **What is Mobile App Testing?**
**[Mobile App testing](https://www.alphabin.co/services/mobile-app-testing)** is the process of validating mobile Apps (Android, IOS) for better functionality, usability, performance, and much more. It can be tested using manual testing and automated testing. Our primary goal is to analyze the app's performance, including some parameters such as user loads and network speed.
## **Popular Types of Mobile App Testing**
**1. Functional Testing:**
It is a type of testing that determines that every aspect of an application is compatible with a software application. It is typically done by a single person or team that works on mobile testing and also it confirms how the user moves throughout the application.
Some common situations need to be evaluated during Mobile app testing as follows:
- First of all on many devices software is installed and launched without facing issue
- Users can easily log in and log out daily basis.
- Ensure that every element in the app like the Navigation button, text, and menu is perfectly functioning.
- keep in mind that the software we are using with a logical user interface and also has a consistent API for the smooth functioning of mobile apps.
**2. Compatibility Testing**
When software runs consistently on various mobile devices is called **[compatibility testing](https://www.alphabin.co/services/compatibility-testing)**.QA engineer is responsible for How well the application adjusts to varying screen sizes and for better device-specific functionalities also remain effective across mobile platforms. These kinds of tests are essential to occur in today's mobile industry.
**3. Usability Testing**
Usability testing focuses on the overall user experience provided by the app. Our primary goal for usability testing is to identify areas of the user experience that need work and present chances for enhancement.
It also contributes to improving the overall functionality and user satisfaction of a product by evaluating the effectiveness with which users accomplish their goals inside it.
**4. Performance Testing**
It is a type of testing used to access computer networks and software programs such as responsiveness and page loading speed. It also allows the measurement and analysis of critical metrics such as response time, **network latency**, and database query This also helps to access how social media, E-commerce, and video streaming apps handle heavy usage and ensure a smooth user experience.
**5. Installation Testing**
Installation testing is a type of software testing that verifies the software testing and also ensures that software is installed correctly on various systems and its configuration it also covers the aspect of the software testing process and also helps us to determine whether software can easily be installed and configured.
## Why Mobile App Testing is so Important?
Mobile app testing is very important for several reasons and also to gain experience on the user side so that before launching the app to the public any technical glitches or errors occur the QA tester can find the error and solve the Bug. For example, if we do not perform the mobile testing without launching the app it may be possible that the app may crash, freeze, or otherwise malfunction on mobile devices.
There are some reasons so that it could be better understand that why mobile app testing is Important in details :
- **Better Quality Assurance:** This type of testing helps us to identify and rectify the defects and bugs that may occur early in the development process. This process also helps to better enhancement of app stability, performance, and usability and leads to a better experience.
- **Interactive User Satisfaction:** By performing this method of testing developer can feel the experience on the user side and also feel how the app looks like and how a user can navigate through it. When users get a great and seamless experience they feel more likely to stay loyal and get some positive feedback.
- **Making Brand Reputation:** A well-performed and tested apps also reflect positive feedback and reviews. While launching of mobile app, when software faces several bugs and malfunctioning files get results in negative reviews and also reduces the customer experience.
- **Compatibility and Performance Testing:** This method of testing signifies the app compatibility and performance such as how the app looks on several devices and how the screen sizes occur. It also evaluates based on performance so that it also improves the network connectivity and app loading speed.
- **Performing Security Testing:** It is very essential to perform security testing when the app is made for fintech and used for payment services, for example, HDFC Bank. By implementing rigorous security testing developer can use their safeguard for the information and also protect from potential Threats.
## **Common Mistakes to Avoid While Running Mobile Apps:**
As we discussed earlier, mobile app testing is the critical phase of the app development life cycle. It can also compromise the quality and reliability of the final product. Some common Mistakes that should be avoided during Mobile app testing which is described as follows:
**1. Failing to Perform Cross-platform Testing:** When a tester fails to perform cross-platform testing then it may cause a serious problem with a mobile App’s usability and functioning.
According to the current diversity of eco mobile systems where users can access apps of different sizes relevant to their screen sizes and also operating systems that depend on consistent performance across the platform.
**2. Incomplete process of Performance Testing:** Users can impact bad reviews by the performance problem. To perform the comprehensive performance testing services we have to evaluate the application’s ability to manage various load and network speeds in the context of variation.
**3. Ignoring the Security Testing:** When the tester ignores the security testing the mobile apps face various malfunctioning threats just as Data leaks, unauthorized access as well and injection attacks. Without an incomplete process of security testing, the mobile app may be found to be at risk. It is essential to prioritize security testing throughout the development life cycle and also developers can protect user data and maintain app integrity.
**4. Incomplete Process of Automated Testing:** If we are continuing with manual testing then it can take so much time and also if we only rely on manual testing.
So **[automated testing](https://www.alphabin.co/services/automation-testing)** is used to manage the repetitive and regression tests effectively. Automated testing also provides constant coverage and also helps to free the tester to work on complicated scenarios by running their test cases.
**5. Neglecting User Feedback:** User feedback is very valuable for understanding the real-world issue and user expectations. It is not a common error in the testing process including user feedback. User feedback plays a vital role on the user side so that if the user finds any type of issue in the app and also any bug occurs he mentions it in the user feedback section. It also helps us to enhance user experience. It also helps to build trust between developer and user so that users feel that the app they are using is more secure and makes the app loyal.
## **Conclusion:**
Testing is very Important for Mobile apps because it helps to identify the bug and solve bugs and also helps to improve overall performance. It also helps to maintain compatibility across the mobile devices. It also defines the app as desirable for all users. It also observed that a well-tested app is more dependable and Trustworthy. Regular Testing also helps to increase our Happiness and usage.

title: The Evolution of Web Development: A Historical Perspective
published: true
---
Since the Internet's inception, web development has undergone significant transformations. Understanding its evolution provides insight into web technologies' current state and future direction. This article explores critical milestones in the history of web development and their impact on the industry.
### The Early Days: Static HTML
In the early 1990s, web pages were static and composed primarily of HTML. They were simple, text-based, and lacked interactivity. Their primary purpose was to share information in a readable format. Developers manually coded HTML, and the web was largely a read-only medium.
### The Advent of CSS and JavaScript
The mid-1990s saw the introduction of CSS (Cascading Style Sheets) and JavaScript, which revolutionized web design and interactivity. CSS allowed developers to separate content from presentation, making it easier to maintain and style websites. JavaScript brought dynamic functionality, enabling user interactions and real-time content updates.
### The Rise of Server-Side Programming
As websites became more complex, server-side programming languages like PHP, ASP, and JSP emerged. These languages allowed for the creating of dynamic web pages that could interact with databases and provide personalized content. E-commerce, content management systems, and web applications began to flourish.
### Web 2.0: User-Generated Content and Social Media
The early 2000s marked the advent of Web 2.0, characterized by user-generated content, social media, and interactive web applications. Platforms like MySpace, Facebook, and YouTube emerged, emphasizing user engagement and content sharing. AJAX (Asynchronous JavaScript and XML) enabled seamless data exchange between the client and server, enhancing the user experience.
### Modern Web Development: Frameworks and Libraries
Today's web development landscape is dominated by powerful frameworks and libraries that streamline development. Frameworks like React, Angular, and Vue.js enable developers to build complex, responsive user interfaces efficiently. These tools provide a structured approach to development, promoting best practices and maintainability.
### The Future: Progressive Web Apps and Beyond
Progressive web apps (PWAs), artificial intelligence, and the continued evolution of web standards are likely to shape the future of web development. PWAs combine the best of web and mobile applications, offering offline capabilities and improved performance. AI integration will enable more personalized and intelligent web experiences.
### Conclusion
The evolution of web development reflects the ongoing quest for better, more interactive, and user-friendly online experiences. From static HTML pages to sophisticated <a href="https://softdevlead.com/comparison-top-frontend-frameworks-for-web-development-in-2024/">frameworks for web development</a>, the journey has been marked by continuous innovation and adaptation. As technology advances, web development will continue to evolve, driving the future of the internet.

1,904,353 | Binary Decision Tree in Ruby ? Say hello to Composite Pattern 🌳 | Decision trees are very common algorithms in the world of development. On paper, they are quite... | 0 | 2024-07-01T07:23:16 | https://dev.to/wecasa/binary-decision-tree-in-ruby-say-hello-to-composite-pattern-h8n | ruby, rails, tutorial, programming | Decision trees are very common algorithms in the world of development. On paper, they are quite simple. You chain if-else statements nested within each other. The problem arises when the tree starts to grow. If you're not careful, it becomes complex to read and, therefore, difficult to maintain.
In this article, we'll see how we implemented decision trees at Wecasa to make them as readable and maintainable as possible.
Before we go any further, let's take some time to define what a Composite is.
## What Links Composite and Binary Decision Tree?
Composite is a structural design pattern. It is a way of arranging objects in a tree structure, which allows us to have a logical hierarchy.
When we talk about a decision tree, we can represent it as boxes that can contain boxes, which can contain boxes, which can contain… a final result.
It's precisely this recursive aspect that makes the decision tree so powerful.
Let's take an example. We want to create a decision tree to calculate the amount of the promotion a customer is eligible for on our e-commerce site.
- In input, our tree receives a User object with all its attributes.
- In output, our tree returns a number.
Each node in our tree has a condition. You can notice by the color code that we have three types of Composites here: Creation Date, Zip Code, and whether the user has already made a purchase. Now that our example is set, let's see how this translates into code!
---
## Firstly, we need tools !
In our implementation of the decision tree, we will need three classes:
1. **The Node Class**: The base class for all other classes. Its purpose is to encapsulate the common logic for all different Nodes in my tree.
```ruby
class Node
attr_accessor :left_node, :right_node
def call(user)
raise NotImplementedError
end
private
# this method is used to ease composites definition
def call_with_condition(user)
if yield
left_node.call(user)
else
right_node.call(user)
end
end
end
```
2. **The Leaf Class**: Its purpose is to end the tree. You can find them as bottom nodes without any child nodes. The only job they have to accomplish is to return the value they encapsulate.
```ruby
class Leaf < Node
attr_accessor :value
def initialize(value)
self.value = value
end
def call(_)
value
end
end
```
3. **The Composite Classes**: Their role is to contain the condition to guide between the success branch and the failure branch, to proceed to the next step in the algorithm. They also contain a method to set arguments. We will see later why this method is useful.
```ruby
class CreationDateComposite < Node
attr_accessor :days
def initialize(left_node, right_node)
self.left_node = left_node
self.right_node = right_node
end
def call(user)
call_with_condition(user) do
self.days.ago > user.created_at
end
end
def set_days(days)
self.days = days
self
end
end
class ZipCodeComposite < Node
[...]
end
class HaveBoughtComposite < Node
[...]
end
```
I only show `CreationDateComposite` so you understand the logic, no need to show the rest.

## How We Finally Manage to Create a Binary Decision Tree
Thanks to all the classes we have built, we will now create our first complete tree. Here is the proposed implementation:
```ruby
class PromotionTree
# We use Singleton because we don't need to rebuild the tree
# everytime we call the class
include Singleton
TREE = CreationDateComposite.new(
ZipCodeComposite.new(
BoughtComposite.new(
Leaf.new(60),
Leaf.new(150)
),
BoughtComposite.new(
Leaf.new(30),
Leaf.new(100)
)
).set_zip_code('75'),
BoughtComposite.new(
Leaf.new(30),
ZipCodeComposite.new(
Leaf.new(75),
ZipCodeComposite.new(
Leaf.new(78),
Leaf.new(0)
).set_zip_code('78')
).set_zip_code('75')
)
).set_days(7).freeze
def call(user)
TREE.call(user)
end
end
```
And now we can simply use the tree :
```ruby
user = User.last
PromotionTree.instance.call(user) # => 60 🎉
```
That being explained, this implementation offers several benefits:
- **No if-else mixed in my business logic**: By encapsulating conditions in separate objects, we have a clear separation of responsibilities. Each condition is handled by a specific composite, making the code more readable, elegant and maintainable.
- **Centralization of conditions in separate objects**: This allows easy reuse and modification of conditions without touching the main application logic. Conditions can be changed or extended by creating new composites or modifying existing ones thanks to OOP.
- **Ease of testing**: Each component of the decision tree can be tested in isolation, simplifying the unit testing process. Tests can focus on specific conditions without having to simulate the entire decision tree.
- **Extensibility**: Adding new conditions or modifying existing conditions is simple and straightforward. Just create new composite nodes and insert them into the existing decision tree.
- **It's easy to build a new tree**: Let's say tomorrow I want to build a new kind of tree. I always have all my Nodes ready to be used.
But apart from this, I can see some downsides :
- **The setup cost is High**: I think it's not that pertinent to use this if you setup this kind of architecture if you don't plan to create other trees.
- **It uses recursion**: The limit of your tree will be the limit of your Stack Size. So if your tree is bigger than your allowed stack size, you won't be able to use it. Fortunately, this value is quite big : 10867 for my setup. But it can depend on your setup !
- **You need to get into the habit to read it quickly**: At first it's kinda disturbing. The fact that we need to read on the top the Composite, and the bottom the value it used is quite weird. But don't be afraid of this syntax, I will publish another article to show you how I implemented a DSL for Tree building based on this architecture.
## Conclusion
Using Composite to implement decision trees allows us to structure our conditions in a clear and maintainable way. Rather than getting lost in a maze of nested if-else statements, we have a logical hierarchy of decisions, each node playing a well-defined role.

1,907,295 | Introduction to Cloud Computing & AWS Cloud Services | Cloud computing refers to the on-demand delivery of IT resources via the Internet, operating on a... | 27,845 | 2024-07-01T07:22:35 | https://dev.to/ansumannn/introduction-to-cloud-computing-aws-cloud-services-50n | aws, cloud, devops, cloudcomputing | Cloud computing refers to the on-demand delivery of IT resources via the Internet, operating on a pay-as-you-go model. Instead of investing in and maintaining physical data centers and servers, users can leverage technology services like computing power, storage, and databases as needed from cloud providers such as Amazon Web Services (AWS).
## Types of Deployment Models
**On-Premises Deployment**:
- Running applications and services on dedicated infrastructure within the organization’s physical premises for maximum control and compliance.
- Although you get complete control and enhanced security with on-premises deployment, the upfront costs and maintenance overhead are substantial and require ongoing investment.
**Cloud Based Deployment**:
- Hosting applications and services entirely on third-party cloud infrastructure(like AWS) for scalability and cost efficiency.
**Hybrid Deployment**:
- Combining cloud-based and on-premises infrastructure to leverage the benefits of both environments.
- This is very flexible but increases complexity in management and integration.
## Benefits of Using Cloud Computing
- **Cost Efficiency**: Cloud computing allows businesses to trade upfront expenses for variable expenses, paying only for the resources they use. This shift from capital expenditures to operational expenditures reduces financial risk and improves budget management.
- **Simplified Operations**: By leveraging cloud services, organizations can eliminate the need to run and maintain their own physical data centers. Cloud providers handle infrastructure management, including hardware maintenance, software updates, and security, freeing up internal IT resources for strategic initiatives.
- **Scalability**: Cloud computing offers unparalleled scalability. Businesses can quickly scale resources up or down based on real-time demand, ensuring they have the right amount of computing power, storage, and networking capabilities without the delays and costs associated with traditional infrastructure scaling.
- **Economies of Scale**: Cloud providers operate massive data centers worldwide, benefiting from economies of scale. This allows them to offer services at a lower cost than would be feasible for individual organizations managing their own infrastructure. Businesses can access enterprise-grade technology and infrastructure without the upfront investment.
- **Speed and Agility**: Cloud computing enables businesses to innovate faster. Developers can provision resources within minutes, deploy applications rapidly, and iterate on software updates seamlessly. This agility helps businesses stay competitive by responding quickly to market changes and customer demands.
- **Global Reach**: With cloud computing, businesses can expand their operations globally with minimal effort. Cloud providers have data centers in multiple geographic regions, allowing businesses to deploy applications closer to their customers for improved performance and compliance with local data regulations. This global infrastructure also enhances disaster recovery and business continuity capabilities.
## What are AWS Cloud Services?
1. **Amazon EC2 (Elastic Compute Cloud)**:
- EC2 provides resizable compute capacity in the cloud. It allows you to run virtual servers (instances) for various workloads, such as web applications, databases, and batch processing.
2. **ELB (Elastic Load Balancing)**:
- ELB automatically distributes incoming application traffic across multiple EC2 instances to ensure optimal performance and fault tolerance of your applications.
3. **AWS SNS (Simple Notification Service)**:
- SNS is a fully managed messaging service that enables you to send notifications from the cloud. It supports multiple communication protocols (HTTP, HTTPS, Email, SMS, etc.) to distribute messages to subscribers or other services.
4. **AWS SQS (Simple Queue Service)**:
- SQS is a fully managed message queuing service that allows you to decouple and scale microservices, distributed systems, and serverless applications. It enables you to send, store, and receive messages between software components without losing messages or requiring other services to be available.
5. **AWS Lambda**:
- Lambda lets you run code without provisioning or managing servers. It automatically scales your application by running code in response to triggers (such as changes in data, HTTP requests, or timers), and you only pay for the compute time consumed.
6. **AWS ECS (Elastic Container Service)**:
- ECS is a highly scalable, fast container management service that allows you to run, stop, and manage Docker containers on a cluster of EC2 instances. It integrates with other AWS services like ELB and IAM for enhanced container management.
7. **AWS EKS (Elastic Kubernetes Service)**:
- EKS provides a managed Kubernetes service that allows you to run Kubernetes clusters on AWS without needing to install, operate, and maintain your own Kubernetes control plane or nodes.
8. **AWS Fargate**:
- Fargate is a serverless compute engine for containers that works with both ECS and EKS. It allows you to run containers without managing the underlying infrastructure. You specify the resources (CPU and memory) needed for your containers, and Fargate handles the rest.
These are some of the 100s of services that aws provides for scalable, reliable, and cost-effective solutions for building and running applications in the cloud, catering to a wide range of use cases from simple web applications to complex, distributed systems.
In the next article, we'll dive deeper into key AWS services like EC2, ELB, etc. exploring their features, how to use, and best practices for implementation. Stay tuned to uncover how these services can transform your cloud computing strategy and drive business success.

1,907,288 | Comparing Lexical Scope for Function Declarations and Arrow Functions | In JavaScript, understanding lexical scope is crucial for understanding how variables are accessed... | 0 | 2024-07-01T07:14:39 | https://dev.to/rahulvijayvergiya/comparing-lexical-scope-for-function-declarations-and-arrow-functions-go3 | In JavaScript, understanding lexical scope is crucial for understanding how variables are accessed and managed within functions. Lexical scope refers to the context in which variables are declared and how they are accessible within nested functions. Let's explore how lexical scope behaves differently between traditional function declarations and arrow functions.
## Function Declarations (Lexical Scope)
Function declarations in JavaScript define functions using the function keyword. They have their own this binding and are hoisted to the top of their scope.
### Example 1: Lexical Scope with Function Declaration
```
function greet() {
let message = "Hello!";
function innerFunction() {
console.log(message); // Accesses message from parent scope
}
innerFunction();
}
greet(); // Output: Hello!
```
**Explanation**: The inner function innerFunction can access the message variable defined in its parent function greet. This is because of lexical scope, where functions can access variables declared in their outer scope.
---
## Arrow Functions (Lexical Scope)
Arrow functions were introduced in ES6 and provide a more concise syntax compared to traditional function declarations. They do not have their own this binding and do not get hoisted.
### Example 2: Lexical Scope with Arrow Functions
```
const greet = () => {
let message = "Hello!";
const innerFunction = () => {
console.log(message); // Accesses message from parent scope
};
innerFunction();
};
greet(); // Output: Hello!
```
**Explanation**: The arrow function innerFunction can also access the message variable from its parent function greet. Despite the use of arrow functions, lexical scope still applies, allowing inner functions to access variables declared in their containing functions.
---
## More Examples of Lexical Scope
### Example 1: Accessing Outer Scope Variables
```
// Function Declaration
function outerFunction() {
let outerVar = "I'm outside!";
function innerFunction() {
console.log(outerVar); // Accesses outerVar from parent scope
}
innerFunction();
}
outerFunction(); // Output: I'm outside!
```
**Explanation**: The inner function innerFunction can access the outerVar variable from its parent function outerFunction due to lexical scope.
### Example 2: Arrow Function Accessing Outer Scope Variables
```
// Arrow Function
const outerFunction = () => {
let outerVar = "I'm outside!";
const innerFunction = () => {
console.log(outerVar); // Accesses outerVar from parent scope
};
innerFunction();
};
outerFunction(); // Output: I'm outside!
```
**Explanation**: Similarly, the arrow function innerFunction can access the outerVar variable from its parent function outerFunction due to lexical scope, just like function declarations.
### Example 3: this Binding Differences function vs arrow function
```
// Function Declaration with `this`
function Counter() {
this.count = 0;
setInterval(function() {
this.count++; // `this` refers to the global object or undefined in strict mode
console.log(this.count);
}, 1000);
}
// Arrow Function with Lexical `this`
function CounterArrow() {
this.count = 0;
setInterval(() => {
this.count++; // `this` refers to CounterArrow's `this`
console.log(this.count);
}, 1000);
}
const counter = new Counter(); // Output increments every second, but `this.count` is not updated as expected.
const counterArrow = new CounterArrow(); // Output increments every second, `this.count` is updated correctly.
```
**Explanation**: In the function declaration (Counter), the this context within setInterval refers to the global object or undefined in strict mode, leading to unexpected behavior when trying to update this.count. In contrast, the arrow function (CounterArrow) maintains the lexical scope of this, ensuring this.count updates correctly within the CounterArrow instance.
## Differences and Considerations
- **this Binding**: Arrow functions do not have their own this context, while function declarations do. This affects how this is accessed within methods and constructors.
- **Hoisting**: Function declarations are hoisted (moved to the top of their scope during compilation), allowing them to be called before they are defined in the code. Arrow functions are not hoisted.
- **Use Cases**: Arrow functions are commonly used in scenarios where a concise syntax and lexical this behavior are beneficial, such as in callbacks or when creating functions that do not rely on this.
## Conclusion
Understanding these differences helps in choosing the appropriate function type based on the requirements of your JavaScript code. Lexical scope ensures that functions, whether declared traditionally or using arrow syntax, can access variables declared in their containing scope, facilitating clear and maintainable code structure.

1,907,280 | Breaking the Blockchain Silos: Exploring Link Network’s Cross-Chain Interoperability | While blockchain technology has revolutionized the management and exchange of digital assets, it... | 0 | 2024-07-01T07:05:07 | https://dev.to/linknetwork/breaking-the-blockchain-silos-exploring-link-networks-cross-chain-interoperability-eho |
While blockchain technology has revolutionized the management and exchange of digital assets, it has brought forth a significant challenge known as “blockchain silos.” This issue refers to the lack of effective interoperability between different blockchains, making it difficult for their respective data and assets to be transferred and interoperated across chains. Link Network provides an effective solution to this challenge by implementing advanced cross-chain interoperability protocols, aiming to break down these silos and build a more open and interconnected blockchain ecosystem.
This interoperability not only enhances the connectivity between different blockchain platforms but also greatly improves the functionality and efficiency of the entire blockchain network. Through Link Network’s technology, assets and information can flow freely, bringing unprecedented convenience and new opportunities to users and enterprises, thus unleashing the full potential of blockchain technology.
The Importance of Cross-Chain Technology
In a diversified blockchain ecosystem, the importance of cross-chain technology is self-evident. It not only addresses compatibility issues between different blockchain platforms but also significantly enhances asset liquidity and expands the possibilities of application scenarios. For example, an asset created on Ethereum can seamlessly transfer to other chains, such as Link Network or Solana, through cross-chain technology, increasing the market exposure and flexibility of these assets.
Moreover, cross-chain technology also provides a broader platform for innovative applications of blockchain. Developers can leverage the characteristics of different chains to design more complex and feature-rich decentralized applications (DApps), such as cross-chain financial services, supply chain management, and decentralized identity verification systems, all of which rely on robust cross-chain communication capabilities to achieve.
Overview of Link Network’s Inter-Chain Protocol
Link Network’s cross-chain interoperability is based on the Inter-Blockchain Communication (IBC) protocol, which is a standard for reliable and secure data transmission between blockchains. The IBC protocol allows independently operated blockchains to connect with each other through specific channels, supporting not only asset transfers but also the exchange of data and state information. This design enables Link Network to serve as the hub for multi-chain applications and services, enhancing the network’s flexibility and scalability.
By implementing IBC, Link Network has established a decentralized network where each chain can maintain its governance independence while securely exchanging information and value when needed. The implementation of this inter-chain communication protocol not only promotes the standardization process of blockchain technology but also lays the foundation for building a global blockchain network.
Technical Details of Achieving Seamless Connectivity
Link Network achieves seamless connectivity between independently operated blockchains through the IBC protocol. This process involves several key components, including clients, connections, channels, and packets. Each client represents a blockchain and is responsible for monitoring and verifying information from other chains it communicates with. This mechanism ensures the authenticity and security of cross-chain data transmission. For example, a client can verify if an asset transfer request from Chain A to Chain B complies with Chain A’s rules and state.
Channels are created on established connections and are responsible for specific data transmission tasks. Each channel is configured with specific data and asset exchange protocols, such as token transfers or smart contract invocations. This layered architecture enables channels to efficiently transmit information between different blockchains, while connections provide the foundational security and protocol support for these channels. Data packets contain specific transaction information, which are packaged and sent from the source chain to the destination chain for execution after verification.
Benefits for Users and Developers
For users, Link Network’s cross-chain technology greatly enhances asset liquidity and availability. Users can easily transfer assets from one blockchain to another without worrying about compatibility issues between different chains. This not only accelerates the transaction process but also reduces transaction costs, improving asset utilization efficiency. For example, users can directly purchase tokens on one chain and use them on another chain without the need for conversion through centralized exchanges.
For developers, cross-chain technology opens the door to innovation. They can design and develop applications that run across multiple blockchain platforms, leveraging the advantages of different chains, such as speed, security, or cost efficiency. Additionally, developers can more easily access the broad blockchain ecosystem through Link Network’s cross-chain protocol, developing more complex and feature-rich distributed applications to meet diverse market and user needs.
Challenges and Solutions
Despite the many advantages brought by cross-chain technology, there are also challenges in its implementation, mainly security and performance issues. For example, cross-chain operations increase the exposure of blockchain networks to potential security risks, such as inter-chain communication becoming a target for attackers. To address this, Link Network adopts multiple security measures, such as encryption techniques, security protocols, and multi-factor authentication
mechanisms, to protect the security of data transmitted between different chains.
Performance issues are also a consideration, as cross-chain communication may increase transaction confirmation times. Link Network addresses this issue by optimizing protocols and enhancing network infrastructure, such as upgrading network nodes and enhancing inter-chain data processing capabilities, to ensure high performance and stability of the network even under high loads. These solutions ensure that Link Network maintains overall efficiency and security while providing cross-chain functionality.
Conclusion
Link Network’s cross-chain interoperability technology is a breakthrough in blockchain development, not only addressing the issue of blockchain silos but also significantly driving the widespread application and development of blockchain technology. By enabling seamless connection and interaction between different blockchains, Link Network not only enhances the overall functionality of the blockchain ecosystem but also increases the liquidity of assets and information, creating tremendous value for global users and developers.
With more blockchain platforms and technologies joining, Link Network’s cross-chain protocol is expected to be further optimized to support more complex interactions and broader application scenarios. Meanwhile, Link Network will continue to face new technical challenges and market demands, continuously upgrading and perfecting its cross-chain technology. In summary, Link Network’s cross-chain interoperability is not only a technological innovation but also a key step in promoting the wider application and acceptance of blockchain technology. | linknetwork | |

Hope you all have been doing great! I was supposed to post an update about 3 days after my last post, but things went south. My AutoCAD crashed, and when I booted everything back up, all my progress was lost.
My Mario Tube was gone, so I had to redo everything. Technically, I have made some progress since the last update, but just a tad bit. I've taken some basic measurements to see if the part will fit into the hole that will be the main base of the turret.
So here is what I have so far. Sorry for the short update, but I wanted to keep you all in the loop. I learned my lesson to save frequently – a big lesson indeed. Still working on this though.
Lesson of the day: Save your work!
Have a great one, and I'll be back to normal posting in 6-7 days with my next update.

To be honest, I've lost count.
I could bore you with the details of how Specify launched or that Product Hunt awarded me Community Member of the Year in 2022 (runner-up).
No. What you probably care about is what my key takeaways are.
So, here we go — what I learned from 42 (or 55) dev-first product launches on Product Hunt.
## Why Product Hunt
**Product Hunt definitely _is_ a great place to launch** — a place where many developer-first products launched successfully: Supabase, Resend, and Warp, to name a few.
According to [similarweb.com](https://www.similarweb.com/website/producthunt.com/#overview), it gets 4.8 million unique visitors every month, and according to [Ahrefs](https://ahrefs.com/website-authority-checker/?input=producthunt.com), it has a 91 domain rating.
Product Hunt helps raise awareness, get feedback, and enable early traction.
Rishabh Kaul, Head of Marketing at Appsmith, who launched in March 2023 and ranked #5 Product of the Day, adds:
> **One of the often overlooked parts of Product Hunt is the reviews that you get during launch. They are customer testimonials for your marketing site.**
> — [Rishabh Kaul](https://www.linkedin.com/in/rishabhkaul), Head of Marketing, Appsmith
**The question isn't _if_ you should launch on Product Hunt. It's *how*.** | fmerian |

How was this week? Have you tried anything new?
Both for work and personal projects, I am studying a lot and this certainly makes me happy; moreover, this allows me to gather some material for newsletters and future articles: what more could I ask for?
Meanwhile, we have also reached the warm season, and the moments of work with slower rhythms are alternated with moments to take a break and let the brain breathe.
For this reason, with today's newsletter, as I had anticipated a few weeks ago, I will close this first "season" (as if it were a series) of MonDEV.
I am doing this to enjoy this period of the year, also to take the time to do some upgrades, both to the newsletter and the website! The plan is to come back around the end of August with richer, more varied, and better organized content, with many new tools, projects, and ideas to share.
In the meantime, I will certainly continue to work on my Open Source projects, so if you happen to want to contribute, see you on [github](https://github.com/Giuliano1993).
Also, if you would like to give me suggestions for a tool, idea, or content that you would like to see covered in the newsletter when it resumes (which I predict will be around the end of August), I am open to every idea! Feel free to contact me, whether under the articles on [Dev.to](https://dev.to/giuliano1993) or on [Linkedin](https://www.linkedin.com/in/giuliano-gostinfini/) or [Twitter](https://x.com/gosty93) and we can have a chat.

1,906,033 | How to Containerize Your Backend Applications Using Docker | Imagine you have spent months meticulously building a backend application. It handles user requests... | 0 | 2024-07-01T07:00:00 | https://dev.to/mlasunilag/how-to-containerize-your-backend-applications-using-docker-3ap7 | devops, docker, aws | Imagine you have spent months meticulously building a backend application. It handles user requests flawlessly, scales beautifully, and is ready to take your product to the next level. But then comes deployment dread. Different environments, dependency conflicts, and a looming fear of something breaking - all potential roadblocks on your path to launch.
Docker solves these problems and gives you a cleaner, more efficient way to package, deploy, and scale your applications. This article will guide you through the process of containerizing your backend application and deploying it to an EC2 instance on Amazon Web Services (AWS).
## What is Docker?
Assume you have a perfect pie recipe, complete with ingredients and instructions, and you bake it using an oven set to 190 degrees Celsius. When your friend tries to bake the same pie using only a microwave that goes up to 140 degrees, it doesn't turn out as expected. You can solve this problem by providing not just the ingredients and recipe, but also the exact oven, kitchen setup, and tools you used. This way, your friend can recreate the exact same pie, regardless of their own kitchen's limitations.
Similarly, [Docker](https://docker.com/) is a tool that helps developers package an application and all its parts—like code, libraries, and system settings—into a "container". This container can run on any computer, making sure the application works the same everywhere. Docker also lets you move these containers around easily, so you can run your app on any computer or even in the cloud without any fuss. And since containers are lightweight, you can spin up as many as you need without hogging too much space or resources. Overall, Docker makes developing and running software smoother, more consistent, and less of a headache.
### How Does Docker Work?
In simple terms, Docker works by creating containers, which are like [virtual machines](https://v2cloud.com/blog/what-is-a-virtual-machine) but much lighter. These containers package up all the code and dependencies needed to run an application, including libraries, system tools, and settings. Docker then runs these containers on any computer, making sure the application runs the same everywhere. It's like having a portable box that contains everything your app needs, so you can easily move it around and run it on any computer without any extra setup.
## Getting Started With Docker
This article will refer to a [Node.js](https://nodejs.org) application built with [NestJS](https://nestjs.com) as an example. To follow along, you'll need a few things:
1. **A Linux Environment:** Linux operating system or a virtual machine running Linux is preferred. If you primarily work with Windows, you can download the [Windows Subsystem for Linux (WSL)](https://learn.microsoft.com/en-us/windows/wsl/install). If you use MacOS, that also works fine.
2. **Docker installed:** Download and install Docker Desktop for your operating system from the [official Docker website](https://www.docker.com/get-started/).
3. **Node.js and npm:** Ensure you have Node.js and [npm](https://www.npmjs.com/) (Node Package Manager) installed on your machine. You can verify this by running `node -v` and `npm -v` in your terminal. If not installed, download them from the official [Node.js website](https://nodejs.org/en/).
4. **A basic NestJS Application**: I will be working with a project called "Dorm Haven". I will assume you have a NestJS application set up. If you do not have one, you can clone [A NestJS project](https://github.com/alexindevs/nestjs-starter-pack) from my GitHub account.
5. **Having an account on Docker Hub:** Sign up for a Docker Hub account at [Docker Hub](https://hub.docker.com/) if you don't already have one. This will be necessary for pushing your Docker images to a remote repository.
6. **Having an AWS Account:** Sign up for an AWS account at [AWS](https://aws.amazon.com/) if you don't already have one. This will be necessary for deploying your application to Amazon EC2.
Now that you have Docker, Node.js, npm, and a basic NestJS application ready, let's containerize your application and deploy it to an EC2 instance on AWS.
### Setting up Docker on your application
1. **Create a file and name it `Dockerfile`**: Note that this file should have no extension. This is a text file that contains a set of instructions to build a Docker image. Each instruction in a `Dockerfile` defines a step in the process of setting up the environment Docker needs to run a specific application. Add the following code to the file:
```
FROM node:20.10.0-alpine
WORKDIR /usr/src/app
COPY . .
RUN npm install
RUN npm run build
ENV NODE_ENV production
EXPOSE 3000
CMD ["npm", "start"]
```
The code above does the following:
- **`FROM node:20.10.0-alpine`:** Sets the base image for the Docker container to the official Node.js Alpine Linux image.
- **`WORKDIR /usr/src/app`:** Changes the working directory to `/usr/src/app`.
- **`COPY . .`:** Copies the entire contents of the local directory to the container's working directory.
- **`RUN npm install`:** Installs NPM packages.
- **`RUN npm run build`:** Builds the Node.js application inside the container.
- **`ENV NODE_ENV production`:** Sets the `NODE_ENV` environment variable to `production`.
- **`EXPOSE 3000`:** Exposes port 3000, so the application can be accessed from outside the container.
- **`CMD ["npm", "start"]`:** Defines the command to start the application.
2. **Build Your Docker Image:** In the root directory of your project, run the following command to build your Docker image. Replace `dorm-haven` with the name of your application:
```bash
$ docker build -t dorm-haven .
```
This command tells Docker to build an image (a lightweight, standalone, executable package that includes everything one needs to run a piece of software) using the instructions in your `Dockerfile` and tag it with the name `dorm-haven`.
3. **Run Your Docker Container:** After building the image, you can run it as a container. Use the following command to start the container:
```bash
$ docker run -p 3000:3000 dorm-haven
```
This command maps port 3000 on your local machine to port 3000 in the Docker container, allowing you to access your application at `http://localhost:3000`.
### Pushing the Docker Image to Docker Hub:
To deploy your application to an EC2 instance on AWS, you first need to push your Docker image to a Docker registry like [Docker Hub](https://hub.docker.com). Follow these steps:
- Log in to Docker Hub using the command:
```bash
$ docker login
```
- Tag your Docker image:
```bash
$ docker tag dorm-haven alexindevs/dorm-haven
```
- Push the image to Docker Hub:
```bash
$ docker push alexindevs/dorm-haven
```
Now that you have your application containerized and ready for deployment, it's time to set up the EC2 instance on AWS.
## Setting up the EC2 instance
1. Log in to your AWS Dashboard. You should see something similar to the screen below.
2. Click on the `Services` option on the navigation bar. Click on Compute, then select EC2.
3. You'll be redirected to the EC2 dashboard. There, click on `Launch Instance`.
4. Enter your server name, and choose an Amazon Machine Image. For this tutorial, I will be using Ubuntu.
5. Next, create a key pair. This will grant you SSH access to your server.
6. Enter a name and choose a key pair type. It is recommended to use the RSA encrypted `.pem` type.
7. Click on `Launch Instance`. This will redirect you to the dashboard shown below. You have successfully created an EC2 instance on AWS!
## Accessing the EC2 instance through SSH
Now your repository is stored on the Docker Hub, and you have an EC2 instance. It is time to navigate to the EC2 instance and deploy your application.
1. Open your instance dashboard and click on `Connect to Instance`. Navigate to the `SSH client` tab.
2. On your terminal, locate your private key and change its permissions as described above. Then run the command. It will grant you access to your instance.
3. Switch to the super user using this command.
```bash
$ sudo su
```
4. Run the following commands to install and set up Docker on the instance.
```bash
$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt install docker.io
$ systemctl start docker
$ systemctl enable docker
```
5. Check that Docker is running.
```bash
$ docker --version
```
6. Login to Docker. This will grant you access to your stored repositories.
```bash
$ docker login
```
7. Pull the uploaded image from the Docker Hub, and confirm that it was downloaded successfully.
```bash
$ docker pull alexindevs/dorm-haven
$ docker images
```
8. After pulling the image, run your Docker container. Map port 80 on your EC2 instance to port 3000 in the Docker container (or any other appropriate port based on your application - make sure to configure your instance to allow public requests on that port).
```bash
$ docker run -d -p 80:3000 alexindevs/dorm-haven
```
The `-d` flag runs the container in detached mode, which means it will run in the background.
9. Verify that your container is running using the following command:
```bash
docker ps
```
### Additional Tips
- **Check Container Logs:**
If you need to check the logs for your container to troubleshoot any issues, use:
```bash
docker logs <container-id>
```
Replace `<container-id>` with the actual container ID from the `docker ps` output.
- **Manage Containers:**
To stop a running container:
```bash
docker stop <container-id>
```
To remove a stopped container:
```bash
docker rm <container-id>
```
## Conclusion
In this article, we walked through the process of setting up Docker, creating a `Dockerfile` for your Node.js application, building and running your Docker container, and finally deploying it to an AWS EC2 instance. By following these steps, you can streamline your deployment process, reduce environment-related issues, and scale your application effortlessly. Thank you for reading!

1,907,251 | How to Track USDT TRC20 Transactions | Tether USDT (TRC20) is a USDT stablecoin issued on the TRON network using the trc20 token standard.... | 0 | 2024-07-01T06:57:56 | https://dev.to/bitquery/how-to-track-usdt-trc20-transactions-565e | tracing, cryptocurrency, cybersecurity, data |
Tether USDT (TRC20) is a USDT stablecoin issued on the TRON network using the trc20 token standard. It is pegged to the US Dollar, which allows it to provide the stability a traditional currency gives while leveraging the benefits of blockchain technology.
By combining the stability of Tether and the efficiency of the TRON network, Tether USDT TRC20 becomes an important tool for crypto traders.
## Understanding TRC20
The TRC20 standard is used to issue and implement tokens on the TRON network. Similarly, as with the Ethereum ERC-20 standard, TRC20 is the standard specially developed for the TRON blockchain, allowing the perfect functioning of tokens within its ecosystem. Tether USDT TRC20 is the representation of the stablecoin Tether, issued according to the standard TRC20 on the TRON network
## Benefits of Tether USDT TRC20
Here are some benefits of Tether USDT TRC20, and why it has become a popular choice for individuals and organizations in the cryptocurrency ecosystem;
- Low Transaction Fees: Transactions involving Tether USDT TRC20 on the Tron network are less expensive than those on other networks.
- Fast Transactions: Transactions on the Tron network are executed quickly, reducing the time required for USDT transfers.

## How to Track Tether USDT TRC20 Transactions Using Bitquery API?
Tracking USDT transactions can be a difficult task due to the decentralized nature of blockchain technology. All cryptocurrency transactions are recorded on the blockchain, providing transparency while also maintaining a sense of anonymity.
This means all wallet addresses are anonymous, making it difficult to link them to actual identities.
However, with blockchain explorers like [Bitquery](https://explorer.bitquery.io/), we can easily search for a specific wallet address and view its entire transaction history.
## Fetching Transactions by Wallet Address
Consider a practical scenario where you need to monitor a specific wallet for Tether USDT TRC20 transactions. Let's break down how you can analyze and interpret the data effectively.
Transaction Volume: By watching daily transfers of USDT, we can spot patterns and unusual changes in transaction levels. Big spikes in activity, like sudden increases in transactions, often mean important events such as large trades, market shifts, or specific wallet actions.
For example, let's look at the [In/Outbound transfer](https://ide.bitquery.io/InOutbound-transfer-count-by-date-from--June-21-2024---June-28-2024) of the wallet address:TL98FzQWz35qsMP93QcXk1vAUfTpqeE3kU from June 21st to June 27th, 2024.
On June 27th, there was a significant rise in activity: 25 deposits and 14 withdrawals. This surge suggests major financial movements, possibly involving large trades or significant payments.
Wallet Activity Insights: By examining USDT TRC20 transactions flowing in and out of a wallet, we can understand its behavior.
This includes how often and how much it transacts, and whether it is mainly accumulating or distributing assets.
Let's look at wallet `TL98FzQWz35qsMP93QcXk1vAUfTpqeE3kU`.
When we look at its transactions, we see significant movements of USDT TRC20 tokens. These large [inflows](https://ide.bitquery.io/inflow-of-USDT-on-Tron) and [outflows](https://ide.bitquery.io/Outflow-of-USDT-on-Tron) suggest that money is being moved around, most likely for storage and accumulation.
Account Management: Analyzing the inflow and outflow of funds in a wallet can give us insights into how the wallet owner manages their money.
- Inflow: Regular large deposits suggest the owner is making consistent investments.
- Outflow: Significant withdrawals could mean the owner is transferring funds to other wallets, or making payments.
Let's look at wallet TL98FzQWz35qsMP93QcXk1vAUfTpqeE3kU.
This wallet shows regular [inflows](https://ide.bitquery.io/inflow-from-june-20-to-june-27) which suggests the owner is making consistent investments. The significant [outflows](https://ide.bitquery.io/outflow-from-June-20th-to-June-27th) indicate regular spending or transfers to other wallets. By examining these transactions, we can see that the owner is maintaining a balanced financial state.
Overall, these observations suggest that the wallet owner is in good financial health by effectively managing their expenses and investments.
By collecting and studying data from many wallets and transactions on the Tron blockchain, we can understand overall market trends and activity. This helps us identify important participants, liquidity sources, and major market changes.

1,907,273 | Building a RESTful API with Spring Boot: A Comprehensive Guide to @RequestMapping | @RequestMapping is a versatile annotation in Spring that can be used to map HTTP requests to handler... | 27,843 | 2024-07-01T06:57:21 | https://dev.to/jottyjohn/building-a-restful-api-with-spring-boot-a-comprehensive-guide-to-requestmapping-49lf | springboot, api | @RequestMapping is a versatile annotation in Spring that can be used to map HTTP requests to handler methods of MVC and REST controllers. Here’s an example demonstrating how to use @RequestMapping with different HTTP methods in a Spring Boot application.
**Step-by-Step Example**
Set up the Spring Boot project as mentioned in my previous post, with Spring Web dependency.
Create a new package for your controller, e.g., com.demo.controller.
Create a new Java class inside this package, e.g., UserController.java.
```
package com.demo.controller;
import org.springframework.web.bind.annotation.*;
@RestController
@RequestMapping("/api/users")
public class UserController {
// GET method to retrieve user details
@RequestMapping(method = RequestMethod.GET, value = "/{userId}")
public String getUser(@PathVariable String userId) {
return "User details for user " + userId;
}
// POST method to create a new user
@RequestMapping(method = RequestMethod.POST)
public String createUser(@RequestBody String user) {
return "User created: " + user;
}
// PUT method to update user details
@RequestMapping(method = RequestMethod.PUT, value = "/{userId}")
public String updateUser(@PathVariable String userId, @RequestBody String user) {
return "User updated for user " + userId + ": " + user;
}
// DELETE method to delete a user
@RequestMapping(method = RequestMethod.DELETE, value = "/{userId}")
public String deleteUser(@PathVariable String userId) {
return "User deleted with userId " + userId;
}
}
```
@RestController: This annotation is used to mark the class as a RESTful controller.
@RequestMapping("/api/users"): This annotation is used at the class level to map all requests that start with /api/users to this controller.
@RequestMapping(method = RequestMethod.GET, value = "/{userId}"): This maps GET requests to /api/users/{userId} to the getUser method. The @PathVariable annotation is used to extract the userId from the URL.
@RequestMapping(method = RequestMethod.POST): This maps POST requests to /api/users to the createUser method. The @RequestBody annotation is used to bind the HTTP request body to a transfer object.
@RequestMapping(method = RequestMethod.PUT, value = "/{userId}"): This maps PUT requests to /api/users/{userId} to the updateUser method. The @PathVariable and @RequestBody annotations are used similarly as before.
@RequestMapping(method = RequestMethod.DELETE, value = "/{userId}"): This maps DELETE requests to /api/users/{userId} to the deleteUser method. | jottyjohn |

It's crucial to understand concepts like hoisting, lexical... | 0 | 2024-07-01T06:56:11 | https://dev.to/rahulvijayvergiya/hoisting-lexical-scope-and-temporal-dead-zone-in-javascript-55pg | webdev, javascript, react, beginners | JavaScript is often a quirky language. It's crucial to understand concepts like **hoisting, lexical scope, and the temporal dead zone (TDZ)**. Rather than just going through theory, let's dive into practical examples that illustrate these concepts, some of which might initially seem confusing.
## Hoisting
Hoisting is JavaScript's behavior of moving declarations to the top of their containing scope during compilation. This can lead to some unexpected results.
### Example 1: Variable Hoisting
```
console.log(myVar); // undefined
var myVar = 5;
console.log(myVar); // 5
```
In this example, you might expect a ReferenceError for the first console.log, but JavaScript "hoists" the declaration of In this example, you might expect a ReferenceError for the first console.log, but JavaScript "hoists" the declaration of myVar to the top, so it exists (but is undefined) before its initialisation. to the top, so it exists (but is undefined) before its initialisation.
### Example 2: Function Hoisting
```
console.log(myFunction()); // "Hello, world!"
function myFunction() {
return "Hello, world!";
}
```
Function declarations are also hoisted, allowing them to be called before their definition in the code.
### Example 3: Hoisting with Function Expressions
When a function is assigned to a variable using var, only the variable declaration is hoisted, not the function assignment. This can lead to different behavior compared to function declarations.
```
console.log(myFunction); // undefined
myFunction(); // TypeError: myFunction is not a function
var myFunction = function() {
console.log("Hello, world!");
};
myFunction(); // "Hello, world!"
```
The variable myFunction is hoisted and initialised to undefined, causing a TypeError when called before the function assignment.
### Example 4: Hoisting Confusion with Var
```
function testHoisting() {
console.log(foo); // undefined
var foo = 'bar';
console.log(foo); // "bar"
}
testHoisting();
```
In testHoisting, foo is hoisted and initialised to undefined, resulting in the first console.log(foo) logging undefined.
### Example 5: Hoisting with Let and Const
```
function testLetConst() {
console.log(bar); // ReferenceError
let bar = 'baz';
console.log(bar); // "baz"
}
testLetConst();
```
Variables declared with let and const are not hoisted to the top, so the first console.log(bar) results in a ReferenceError.
---
## Lexical Scope
Lexical scope means that the scope of a variable is determined by its position in the source code.
### Example 1: Nested Functions (Lexical Scope)
```
function outerFunction() {
var outerVar = 'I am outside!';
function innerFunction() {
console.log(outerVar); // "I am outside!"
}
innerFunction();
}
outerFunction();
```
Here, **innerFunction** can access **outerVar** because it is defined within the same lexical scope.
### Example 2: Scope Confusion (Lexical Scope)
```
var x = 10;
function foo() {
var x = 20;
bar();
}
function bar() {
console.log(x); // 10
}
foo();
```
One might expect bar() to print 20, but it prints 10 because bar is defined in the global scope, where x is 10.
### Example 3: Lexical Scope and Closures (Lexical Scope)
```
function createFunction() {
var localVar = 'local';
return function() {
console.log(localVar); // "local"
};
}
var myFunction = createFunction();
myFunction();
```
myFunction retains access to localVar even after createFunction has finished executing, demonstrating a closure
### Example 4: Lexical Scope in Loops (Lexical Scope)
```
for (var i = 0; i < 3; i++) {
setTimeout(function() {
console.log(i); // 3, 3, 3
}, 1000);
}
for (let j = 0; j < 3; j++) {
setTimeout(function() {
console.log(j); // 0, 1, 2
}, 1000);
}
```
The var declaration in the first loop results in i being hoisted to the global scope, so all three setTimeout callbacks log 3. The let declaration in the second loop creates a new j for each iteration, so the callbacks log 0, 1, and 2.
### Example 5: Comparing Lexical Scope for Function Declarations and Arrow Functions
I think this topic is big enough to complete in one example, so i created a article about it, [here is the link](https://dev.to/rahulvijayvergiya/comparing-lexical-scope-for-function-declarations-and-arrow-functions-go3)
---
## Temporal Dead Zone (TDZ)
The TDZ refers to the period between the entering of a scope and the actual declaration of variables, where they cannot be accessed.
### Example 1: Let and Const - Temporal Dead Zone (TDZ)
```
console.log(a); // ReferenceError
let a = 5;
```
Unlike var, variables declared with let and const are not hoisted to the top of their block scope, resulting in a ReferenceError if accessed before their declaration.
### Example 2 - Temporal Dead Zone (TDZ)
```
{
console.log(b); // ReferenceError
let b = 10;
}
{
let c = 20;
console.log(c); // 20
}
```
In the first block, accessing b before its declaration results in a ReferenceError due to the TDZ. In the second block, c is accessed after its declaration, so it logs 20.
### Example 3: Temporal Dead Zone with Functions
```
{
console.log(func); // ReferenceError
const func = function() {
return 'Hello!';
};
}
{
const func = function() {
return 'Hello!';
};
console.log(func()); // "Hello!"
}
```
In the first block, accessing func before its declaration results in a ReferenceError due to the TDZ. In the second block, func is accessed after its declaration, so it works as expected.
## Combining Concepts
### Example 1: Hoisting and TDZ
```
{
console.log(d); // ReferenceError
let d = 15;
console.log(d); // 15
}
```
This example shows how accessing a let variable before its declaration results in a ReferenceError due to the TDZ, even though the declaration is hoisted to the top of the block.
### Example 2: Lexical Scope and Hoisting
```
var e = 30;
function test() {
console.log(e); // undefined
var e = 40;
console.log(e); // 40
}
test();
console.log(e); // 30
```
In test(), e is hoisted and initialised to undefined within the function scope, so the first console.log(e) logs undefined.
### Example 3: Hoisting, Lexical Scope, and TDZ Combined
```
let f = 50;
function outer() {
console.log(f); // 50
let f = 60;
inner();
function inner() {
console.log(f); // ReferenceError
}
}
outer();
```
Here, inner is defined within the scope of outer, but f is in the TDZ within outer before its declaration, leading to a ReferenceError when inner tries to access it.
## Conclusion
Understanding **hoisting, lexical scope, and the temporal dead zone** is vital for writing robust JavaScript code. These examples illustrate how JavaScript handles variable and function declarations, scopes, and the strange behaviour of accessing variables before their declaration. By experimenting with these concepts, you'll develop a more intuitive grasp of JavaScript's behaviour.

In this blog post, we will explore how to build a Digital Audio Workstation (DAW) in React. We will use the Tone.js library to create music and audio effects, and we will discuss the key components and features of a DAW application.
## Introduction
A Digital Audio Workstation (DAW) is a software application used for recording, editing, and producing audio files. DAWs are commonly used by musicians, sound engineers, and producers to create music, podcasts, and other audio content.
In this tutorial, we will dive into the logic of **Liberty Beats**, a simple (but powerful) DAW application in React that allows users to create and edit music tracks.
The application is built using React components, state management, and the [Tone.js](https://tonejs.github.io/) library for audio synthesis and effects.
## First Steps
Before we start building the DAW application, let's outline the key features and components that we want to include:
- **Track Editor**: A visual interface for creating and editing music tracks. Users can add, remove, and modify audio clips, adjust volume and panning, and apply effects.
- **Transport Controls**: Play, pause, stop, and seek controls for playback. Users can control the tempo from the panel.
- **Mixer**: A mixer section for each track, where users can adjust volume, set solo and mute options.
## Create a Vite React App and Set Up Tone.js
To get started, we will create a new React application using [Vite](https://vitejs.dev/), a fast build tool that supports React and modern JavaScript features.
Then, follow my previous blog post on how to [integrate Tone.js in a React application](https://blog.coluzziandrea.com/react-tonejs) to set up Tone.js in your project.
## Create a store for the DAW
In Liberty Beats, we used Redux Toolkit to manage the application state. [Redux Toolkit](https://redux-toolkit.js.org/) is a powerful library that simplifies the process of managing state in React applications.
Once you have set up Redux Toolkit in your project, you can create a store for the DAW application. The store will hold the state of the application, and the most important part is the playlist slice, which will contain the tracks and their settings.
Here's the type of the track object, taken from the [Liberty Beats](https://github.com/coluzziandrea/liberty-beats) project:
```javascript
export interface Track {
id: string
title: string
/**
* Tailwind CSS color class
* @example 'green'
*/
color: TrackColor
instrumentPreset: InstrumentPreset
/**
* Drums track specific data (can be undefined if track is not drums track)
*/
trackDrums?: TrackDrums
bars: Bar[]
volume: number
muted: boolean
soloed: boolean
areThereAnyOtherTrackSoloed: boolean
}
```
In the `Track` interface, we define the properties of a track:
- `id`: A unique identifier for the track.
- `title`: The name of the track.
- `color`: A Tailwind CSS color class for the track (values set in the `TrackColor` enum).
- `instrumentPreset`: The instrument preset for the track, defined in the `InstrumentPreset` enum.
- `trackDrums`: Specific data for drums tracks (can be `undefined` if the track is not a drums track). Drums need a different representation in the UI, and also different settings when it comes to the sequencer.
- `bars`: An array of `Bar` objects, representing the bars in the track. Each `Bar` object contains the notes for each step in the bar.
- `volume`: The volume level of the track.
- `muted`: A boolean value indicating whether the track is muted.
- `soloed`: A boolean value indicating whether the track is soloed.
- `areThereAnyOtherTrackSoloed`: A boolean value indicating whether there are other tracks soloed in the playlist.
## Building the Editor
Building the Editor is one of the most challenging parts of the DAW application. The Editor is a grid-based interface where users can create and edit music patterns by placing notes on a grid.
In Liberty Beats, we used a custom Editor component that allows users to create and edit music patterns for each track. The Editor component is built using React and Tone.js, and it provides a visual interface for creating and editing music patterns.
At the very beginning of the project, the Grid was made using a simple HTML table, but then I switched to a more performant solution using a canvas element. The canvas element allows for better performance and more flexibility when it comes to drawing the grid and the notes.
Here's a simplified version of the Editor component in Liberty Beats:
```javascript
import React, { useEffect, useRef } from 'react'
import { Bar, Note } from '../types'
import { drawGrid, drawNotes } from '../utils/draw'
interface EditorProps {
bars: Bar[]
onNoteClick: (barIndex: number, stepIndex: number) => void
}
const Editor: React.FC<EditorProps> = ({ bars, onNoteClick }) => {
const canvasRef = useRef<HTMLCanvasElement>(null)
useEffect(() => {
if (canvasRef.current) {
const canvas = canvasRef.current
const ctx = canvas.getContext('2d')
if (ctx) {
drawGrid(ctx, bars)
drawNotes(ctx, bars)
}
}
}, [bars])
const handleClick = (event: React.MouseEvent<HTMLCanvasElement>) => {
const rect = event.currentTarget.getBoundingClientRect()
const x = event.clientX - rect.left
const y = event.clientY - rect.top
const stepIndex = Math.floor(x / 20)
const barIndex = Math.floor(y / 20)
onNoteClick(barIndex, stepIndex)
}
return (
<canvas
ref={canvasRef}
width={bars[0].notes.length * 20}
height={bars.length * 20}
onClick={handleClick}
/>
)
}
export default Editor
```
## Implementing the Transport layer
The Transport layer is responsible for controlling the playback of the tracks in the DAW application. It provides controls for playing, pausing, stopping, and seeking the playback of the tracks.
In Liberty Beats, we used the Tone.Transport object from the Tone.js library to control the playback of the tracks. The Transport layer provides controls for starting, stopping, and seeking the playback of the tracks, as well as setting the tempo and time signature.
Using the store as a source of truth, we can easily control the playback of the tracks in the application. Here's a simplified version of the Transport component in Liberty Beats:
```javascript
import React from 'react'
import { useDispatch, useSelector } from 'react-redux'
import { selectPlaylist, setPlaying } from '../store/playlistSlice'
const Transport: React.FC = () => {
const dispatch = useDispatch()
const playlist = useSelector(selectPlaylist)
const handlePlay = () => {
dispatch(setPlaying(true))
}
const handlePause = () => {
dispatch(setPlaying(false))
}
const handleStop = () => {
dispatch(setPlaying(false))
}
return (
<div>
<button onClick={handlePlay}>Play</button>
<button onClick={handlePause}>Pause</button>
<button onClick={handleStop}>Stop</button>
</div>
)
}
export default Transport
```

During my discussion with our guest Gaurav Batra, CTO at Semaai (a hyper-growth agritech startup from Indonesia), he mentioned about the criticality of optimizing their engineering team's productivity. In this article, we aim to share his journey as a CTO, and tech advisor, the challenges he faced, and the strategies he implemented to boost productivity in his own dev teams at Semaai and other growth-stage startups. I hope these insights can serve as a valuable guide for other engineering leaders.
How do you define Developer Productivity?
Developer productivity, in fundamental terms, refers to the efficiency and effectiveness with which software developers can complete their tasks and contribute to the company's goals. It encompasses various aspects, including:
Code Quality: Writing clean, maintainable, and bug-free code.
Development Speed: The pace at which developers can deliver features and fixes.
Collaboration: How well developers work together and with other teams.
Innovation: The ability to come up with creative solutions and improvements.
Work-Life Balance: Ensuring that developers maintain a healthy balance to avoid burnout.
Several factors impact developer productivity, such as:
Tooling and Infrastructure: The quality and suitability of development tools and platforms.
Processes and Workflows: How tasks are organized, prioritized, and managed.
Team Dynamics: Communication, collaboration, and team cohesion.
Work Environment: Physical and psychological conditions in the workplace.
Skills and Training: The knowledge and competencies of the developers.
The Journey: Challenges and Solutions
When we started out, we faced numerous challenges that hindered our developers' productivity. Here are some key problems and the solutions we implemented:
Problem: Inefficient Tooling
Solution: We conducted a thorough audit of our development tools and identified areas for improvement. We invested in modern IDEs, faster build systems, and automated testing frameworks. This reduced the time developers spent on mundane tasks and allowed them to focus more on coding and problem-solving.
Problem: Poor Processes and Workflows
Solution: We introduced agile methodologies, including Scrum and Kanban, to streamline our workflows. Regular stand-up meetings, sprint planning, and retrospectives helped us keep track of progress and address bottlenecks promptly. This not only improved task management but also fostered a culture of continuous improvement.
Problem: Lack of Collaboration
Solution: To enhance collaboration, we implemented Slack for communication and Confluence for documentation. We also encouraged pair programming and code reviews, which not only improved code quality but also facilitated knowledge sharing among team members.
Problem: Skills Gap
Solution: Continuous learning and development were key to addressing this issue. We provided access to online courses, hosted internal tech talks, and supported attendance at industry conferences. This empowered our developers to stay updated with the latest technologies and best practices.
But, did it lead to any positive outcomes?
To ensure that our efforts were yielding results, we adopted several data-driven measures:
Cycle Time: We measured the time taken from code commit to deployment to assess the speed of delivery.
Pull Request Reviews: We monitored the number and quality of pull request reviews to ensure thoroughness and knowledge sharing.
Project Completion Rates: We tracked the completion rates of projects and features to evaluate overall increase in efficiency.
Developer Experience Surveys: Regular surveys helped us gather feedback on what was working and what needed improvement.
We saw a positive change in these metrics, driven with actionable insights and helped us make informed decisions to further enhance productivity.
Last words
Boosting developer productivity is an ongoing process that requires attention to detail and a willingness to adapt. By focusing on efficient tooling, streamlined processes, collaborative practices, a supportive work environment, and continuous learning, we were able to significantly improve our team's productivity. I hope our experiences inspire other engineering leaders to implement similar strategies and drive productivity within their own teams.
Feel free to reach out if you have any questions or would like to share your own experiences.
