Maximum Total Importance of Roads
Medium
You are given an integer `n` denoting the number of cities in a country. The cities are numbered from `0` to `n - 1`.
You are also given a 2D integer array roads where <code>roads[i] = [a<sub>i</sub>, b<sub>i</sub>]</code> denotes that there exists a **bidirectional** road connecting cities <code>a<sub>i</sub></code> and <code>b<sub>i</sub></code>.
You need to assign each city with an integer value from `1` to `n`, where each value can only be used **once**. The **importance** of a road is then defined as the **sum** of the values of the two cities it connects.
Return _the **maximum total importance** of all roads possible after assigning the values optimally_.
**Example 1:**
- **Input:** n = 5, roads = [[0,1],[1,2],[2,3],[0,2],[1,3],[2,4]]
- **Output:** 43
- **Explanation:** The figure above shows the country and the assigned values of [2,4,5,3,1].
- The road (0,1) has an importance of 2 + 4 = 6.
- The road (1,2) has an importance of 4 + 5 = 9.
- The road (2,3) has an importance of 5 + 3 = 8.
- The road (0,2) has an importance of 2 + 5 = 7.
- The road (1,3) has an importance of 4 + 3 = 7.
- The road (2,4) has an importance of 5 + 1 = 6.
- The total importance of all roads is 6 + 9 + 8 + 7 + 7 + 6 = 43.
- It can be shown that we cannot obtain a greater total importance than 43.
**Example 2:**
- **Input:** n = 5, roads = [[0,3],[2,4],[1,3]]
- **Output:** 20
- **Explanation:** The figure above shows the country and the assigned values of [4,3,2,5,1].
- The road (0,3) has an importance of 4 + 5 = 9.
- The road (2,4) has an importance of 2 + 1 = 3.
- The road (1,3) has an importance of 3 + 5 = 8.
- The total importance of all roads is 9 + 3 + 8 = 20.
- It can be shown that we cannot obtain a greater total importance than 20.
**Constraints:**
- <code>2 <= n <= 5 * 10<sup>4</sup></code>
- <code>1 <= roads.length <= 5 * 10<sup>4</sup></code>
- <code>roads[i].length == 2</code>
- <code>0 <= a<sub>i</sub>, b<sub>i</sub> <= n - 1</code>
- <code>a<sub>i</sub> != b<sub>i</sub></code>
- There are no duplicate roads.
**Solution:**
```
class Solution {
/**
* @param Integer $n
* @param Integer[][] $roads
* @return Integer
*/
function maximumImportance($n, $roads) {
$ans = 0;
$count = array_fill(0, $n, 0);
foreach ($roads as $road) {
$u = $road[0];
$v = $road[1];
++$count[$u];
++$count[$v];
}
sort($count);
for ($i = 0; $i < $n; ++$i) {
$ans += ($i + 1) * $count[$i];

BitPower's smart contracts have undergone rigorous code audits and testing to ensure their logical correctness and vulnerability protection capabilities. Specifically, BitPower smart contracts have the following characteristics:
Transparency: The code of all smart contracts is open source and can be viewed and audited by anyone. This transparency not only enhances user trust, but also allows community members to discover and report potential vulnerabilities.
Immutability: Once a smart contract is deployed on the blockchain, its code and data will not be tampered with. This means that no one can unilaterally modify the contract rules, ensuring the stability and fairness of the system.
Automated execution: Smart contracts automatically execute transactions and operations through preset conditions and logic, avoiding human intervention and operational errors. This automated feature not only improves transaction efficiency, but also further reduces risks.
Data security and privacy protection
On the BitPower platform, user data security and privacy protection are also highly valued. First, all transaction data is recorded on the blockchain, which is highly transparent and tamper-proof. Secondly, BitPower uses advanced encryption technology to ensure that users' sensitive information is not leaked or tampered with during transmission and storage. In addition, the platform uses privacy protection technologies such as zero-knowledge proof to maximize user privacy while ensuring transaction transparency.
Comprehensive security mechanism
In addition to the above technical measures, BitPower has also implemented a series of comprehensive security mechanisms to fully protect the security of the platform:
Multi-signature mechanism: In fund transfers and important operations, BitPower adopts a multi-signature mechanism to ensure that any important operation requires multiple independent signature authorizations, further improving security.
Risk control system: BitPower has built-in a powerful risk control system to monitor all transactions and operations on the platform in real time, and promptly detect and prevent abnormal behavior and potential attacks.
Insurance fund: In order to deal with emergencies and unforeseen risks, BitPower has established a special insurance fund. Once user assets are lost due to platform vulnerabilities or other reasons, the insurance fund will provide corresponding compensation to protect the rights and interests of users.

1,904,497 | Using Reverse Auctions for Government Procurement | Explore the innovative approach of reverse auctions in government procurement, and how it drives efficiency and cost savings. | 0 | 2024-06-28T16:41:46 | https://www.govcon.me/blog/using_reverse_auctions_for_government_procurement | government, procurement, reverseauctions, technology | # Using Reverse Auctions for Government Procurement
When it comes to government procurement, efficiency, transparency, and cost savings are paramount. Traditional procurement methods often fall short of these goals, leading to delays, increased costs, and a lack of competition. Enter *reverse auctions*, a revolutionary approach that flips the script on conventional purchasing.
## What is a Reverse Auction?
Imagine your typical auction: sellers compete to offer the highest bid. A reverse auction turns this concept on its head. Here, sellers compete to offer the lowest bid. The government, acting as the buyer, sets the terms and conditions, while suppliers vie to provide their goods or services at the lowest price. This method not only encourages competitive pricing but also ensures transparency in the selection process.
## The Mechanics Behind Reverse Auctions
Reverse auctions are typically conducted online via specialized platforms. Here's a high-level overview of how it works:
1. **Preparation Phase**
- **Identify Needs**: Government agencies identify the goods or services needed.
- **Set Specifications**: Detailed requirements and specifications are prepared.
- **Choose Auction Platform**: An appropriate online auction platform is selected.
2. **Auction Phase**
- **Invitations Sent**: Potential suppliers are invited to participate.
- **Bid Submission**: Suppliers submit their bids within a specified timeframe.
- **Dynamic Bidding**: Suppliers can see the current lowest bid (without knowing the bidder's identity) and adjust their bids accordingly.
3. **Award Phase**
- **Bid Evaluation**: Bids are evaluated based on predefined criteria, not just price but also quality and delivery capability.
- **Contract Award**: The contract is awarded to the supplier with the best offer.
## Benefits of Reverse Auctions in Government Procurement
### 1. **Cost Savings**
Reverse auctions foster competitive pricing, often leading to significant cost reductions. With suppliers vying to offer the lowest bid, the government can procure goods and services at highly competitive rates.
### 2. **Efficiency**
The streamlined approach of reverse auctions eliminates the cumbersome paperwork and prolonged negotiation phases typical of traditional procurement methods. This leads to faster award times and quicker project starts.
### 3. **Transparency**
Every bid and bidding activity is documented and visible, ensuring a transparent process. This reduces the risk of corruption and builds public trust in government procurement practices.
### 4. **Enhanced Competition**
By lowering the barrier to entry, reverse auctions promote wider participation from a diverse pool of suppliers. This is particularly beneficial for small and medium-sized enterprises (SMEs) that may have been previously excluded from the procurement process.
### 5. **Improved Supplier Relations**
A clear and objective bidding process can improve relations between the government and suppliers. Suppliers appreciate the fairness and clarity of reverse auctions, which can lead to more positive long-term relationships.
## Technical Considerations
Implementing reverse auctions require robust technology platforms capable of handling several aspects, including:
- **Real-Time Bidding**: The platform must support real-time bid submissions and updates.
- **Secure Environment**: Ensuring data privacy and secure transactions is paramount.
- **User-Friendly Interface**: Both government officials and suppliers should easily navigate the system.
- **Compliance and Reporting**: The platform should facilitate compliance with government procurement regulations and provide comprehensive reporting capabilities.
## Challenges and Mitigation Strategies
Like any innovative approach, reverse auctions come with challenges:
### 1. **Resistance to Change**
Resistance from stakeholders accustomed to traditional methods can hinder adoption. **Mitigation**: Comprehensive training and demonstration of benefits.
### 2. **Technical Issues**
A robust, glitch-free platform is essential. **Mitigation**: Partner with experienced technology providers to ensure reliability.
### 3. **Quality Concerns**
Lowest bid doesn't always guarantee the best quality. **Mitigation**: Implement a dual-criteria evaluation system focusing on both price and quality.
## Conclusion
Reverse auctions represent a game-changing approach to government procurement. By promoting competition, ensuring transparency, and driving cost savings, this innovative technique aligns perfectly with the goals of modern public administration. As technology continues to advance, the potential for reverse auctions to revolutionize procurement practices becomes increasingly promising. It's time for governments globally to embrace this strategy and pave the way for a more efficient and transparent procurement process.

## Introduction <a name="introduction"></a>
Our goal was to be able to run Reth on a RISC-V GNU Linux. Why? Because:
1. We believe it enhances client diversity. It's not only about what is the most used client implementation, but also what hardware it runs on.
2. It's an amazing challenge. We learned many things about cross-compilation, QEMU and the tools used in Reth.
3. Extending the previous reason, we just wanted to share our journey with the community. Maybe it'll help some of you get started on RISC-V, exploring QEMU and more.
We'll explain how we managed to configure a RISC-V environnement, how we cross-compiled Reth for the RISC-V target and present the tools used to achieve it. We'll also recap the limitations we currently know about.
## The RISC-V environnement <a name="the-risc-v-environnement"></a>
In this first section, we describe how we failed to run Reth on a non-compatible bare-metal environnement, which led us to use a VM with the help of QEMU.
### Bare Metal <a name="bare-metal"></a>
At the beginning, we really wanted to run Reth on a bare-metal server with a RISC-V processor.
We used the [Elastic Metal RV1 instances from Scaleway](https://labs.scaleway.com/en/em-rv1/) but faced a first error we previously encountered when trying to run Reth on ARM64 machines: the virtual memory layout on Linux.
In a nutshell, the Linux kernel can be compiled to use a specific virtual memory layout, but the hardware on the machine might not support all of them.
Scaleway's instances only support SV39 mode at best, while we need SV48 at least. Not using a proper virtual memory layout leads to an error which was [documented in the Reth issue here](https://github.com/paradigmxyz/reth/issues/2211) .
On RISC-V Linux, the SV39 mode allows up to 256 GB of user-space virtual memory while the SV48 allows up to 128 TB - as specified in the [kernel documentation](https://www.kernel.org/doc/html/v6.4-rc7/riscv/vm-layout.html).
Check-out the issue linked above to learn more about the underlying reasons of why this is an issue for Reth, onbjerg did an amazing job explaining it in simple terms.
When we started the project, Scaleway was the only cloud provider with RISC-V instances and we did not have a dev board at home, which led us to look for another setup: using QEMU to create a RISC-V VM.
### QEMU to the rescue <a name="qemu-to-the-rescue"></a>
We tried to follow the [official documentation for running Linux on QEMU for RISC-V](https://risc-v-getting-started-guide.readthedocs.io/en/latest/linux-qemu.html) but faced too many compilation errors on macOS with Apple Silicon.
As we had a Ubuntu machine with an x86 CPU on Hetzner for development purposes, we decided to immediately switch.
After following the instructions to compile QEMU with RISC-V compatibility and running a compatible Debian image (amazing blog post with the [instructions here](https://colatkinson.site/linux/riscv/2021/01/27/riscv-qemu/)), it worked!
You can connect to the VM using:
```bash
ssh root@localhost -p 2222 # Passord: root
```
```bash
root@debian:~# uname -r
6.8.12-riscv64
root@debian:~# cat /proc/cpuinfo
...
mmu : sv57 # Sweet, this virtual memory layout allows up to 64 PB user-space virtual memory. Enough to store da blobs.
...
```
Note that the provided image only has a 10 GB-size disk. If you'd like to extend it consider taking a look at this [SO answer](https://serverfault.com/questions/324281/how-do-you-increase-a-kvm-guests-disk-space) and then resizing the FS using `fdisk` (be careful, when expanding the root partition, the first sector might not be the default one) and `resize2fs`.
The development environnement is ready. Now is the time to build and run Reth.
## Cross-Compiling Reth <a name="cross-compiling-reth"></a>
To compile Reth for the RISC-V 64 target, we have different options:
- Compile natively inside the VM. Slow but less prone to errors and requires less configuration tweaks.
- Compile using the cross-compiler. Requires to setup the tools first but leads to way faster compilation time.
The first option is actually really easy: just follow the official documentation to [build Reth from source](https://reth.rs/installation/source.html) from within the VM.
The second option is a bit more complex: we can either use install the cross-compiler from a package manager or build it from source.
As your distribution may very from our own, we chose to build it from the [official toolchain sources](https://github.com/riscv-collab/riscv-gnu-toolchain). In fact, we built a [Docker image](https://hub.docker.com/layers/quartztech/riscv-gnu-toolchain/latest/images/sha256-5e97020d214ba5abc16709db4f1e3c39c2c0cc5417fb901506a3297284af62b7?context=repo) which contains the RISC-V toolchain built from source for both the `amd64` and `arm64` platforms.
From there, it's as easy as just running `cargo build` right? Well, there are two details.
The cross-compilation target must be specified and requires some extra parameters, and the MDBX auto-generated bindings requires extra-configuration.
### Cross-Compilation Target <a name="cross-compilation-target"></a>
When cross-compiling in Rust using cargo, the target can be specified using the `--target` flag.
Here, we will inform cargo that the target is `riscv64gc-unknown-linux-gnu`.
One thing we discovered was that another target we aimed for, `riscv64gc-unknown-none-elf`, is not yet fully supported by Rust. Namely, it does not support std right now and therefore Reth cannot be cross-compiled for this target.
During the cross-compilation, the linker also must be specified manually, and we chose the easiest way (an environnement variable) to do so:
```bash
export CARGO_TARGET_RISCV64GC_UNKNOWN_LINUX_GNU_LINKER=riscv64-unknown-linux-gnu-gcc
```
But if we try to build Reth, the compilation will fail due to the custom `mdbx-sys` crate build process.
```bash
...
33.85 error: failed to run custom build command for `reth-mdbx-sys v1.0.0 (/build/crates/storage/libmdbx-rs/mdbx-sys)`
33.85
33.85 Caused by:

33.85 /usr/include/stdint.h:26:10: fatal error: 'bits/libc-header-start.h' file not found
...
```
Let's fix it by tweaking the bindgen configuration.
### MDBX Bindgen Configuration <a name="mdbx-bindgen-configuration"></a>
To build the `mdbx-sys` crate bindings, the bindgen tool is used. As it uses clang to generate the C/C++/Rust bindings, it does not know about the RISC-V toolchain and we must specify it manually.
Hopefully, as stated in the bindgen's README, we can pass extra flags to clang using the `BINDGEN_EXTRA_CLANG_ARGS` environnement variables (we could also tweak the `build.rs` file in the crate, but we did not wanted to temper with the sources).
```bash
# The sysroot for the quartztech/riscv-gnu-toolchain image is in /usr/local/
export BINDGEN_EXTRA_CLANG_ARGS="--sysroot=/usr/local/sysroot"
```
Finally, we can build Reth.
## Building Reth <a name="building-reth"></a>
Here's the command to build reth using our RISC-V cross-compiler:
```bash
cargo build --release --target riscv64gc-unknown-linux-gnu
```
### Wrapping Up <a name="wrapping-up"></a>
#### Custom Docker image for RISC-V toolchain <a name="custom-docker-image-for-risc-v-toolchain"></a>
Here's our Dockerfile used as the based image in the next sub-section.
It contains the RISC-V toolchain built from source.
```dockerfile
FROM ubuntu:22.04 AS builder
WORKDIR /build
RUN apt-get update && apt-get install -y \
autoconf \
automake \
autotools-dev \
curl \
python3 \
python3-pip \
libmpc-dev \
libmpfr-dev \
libgmp-dev \
gawk \
build-essential \

patchutils \
bc \
zlib1g-dev \
libexpat-dev \
ninja-build \
git \
cmake \
libglib2.0-dev \
libslirp-dev
RUN git clone https://github.com/riscv/riscv-gnu-toolchain .
# Newlib installation.
RUN ./configure --enable-multilib
RUN make
# Linux installation.
RUN ./configure --enable-multilib
RUN make linux
FROM ubuntu:22.04 AS runtime
WORKDIR /
COPY --from=builder /usr/local /usr/local
ENTRYPOINT [ "/bin/bash" ]
```
#### Using the non-trivial approach <a name="using-the-non-trivial-approach"></a>
For the braves, here's a Dockerfile which uses the Quartz base image to cross-compile Reth:
```dockerfile
FROM quartztech/riscv-gnu-toolchain:latest
WORKDIR /build
ENV PATH=/opt/riscv/bin:$PATH
RUN apt-get update && apt-get install -y \
curl \
build-essential \
git \
pkg-config \
libssl-dev \
libclang-dev
RUN curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- -y
ENV PATH=/root/.cargo/bin:$PATH
RUN rustup target add riscv64gc-unknown-linux-gnu
RUN git clone https://github.com/paradigmxyz/reth .
ENV CARGO_TARGET_RISCV64GC_UNKNOWN_LINUX_GNU_LINKER=riscv64-unknown-linux-gnu-gcc
ENV BINDGEN_EXTRA_CLANG_ARGS="--sysroot=/usr/local/sysroot"
RUN cargo build --release --target riscv64gc-unknown-linux-gnu
ENTRYPOINT [ "/bin/bash" ]
```
#### Using a simpler approach <a name="using-a-simpler-approach"></a>
Now if you use a simpler method and just install the toolchain from a package manager, here's what the Dockerfile would look like (with Ubuntu as the base image at least):
```dockerfile
FROM ubuntu:22.04
WORKDIR /build
RUN apt-get update && apt-get install -y \
curl \
build-essential \
git \
pkg-config \
libssl-dev \
libclang-dev \
# All of this article for this change ^^, I love reinventing the wheel.
gcc-riscv64-linux-gnu
RUN curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- -y
ENV PATH=/root/.cargo/bin:$PATH
RUN rustup target add riscv64gc-unknown-linux-gnu
RUN git clone https://github.com/paradigmxyz/reth .
ENV CARGO_TARGET_RISCV64GC_UNKNOWN_LINUX_GNU_LINKER=riscv64-linux-gnu-gcc
RUN cargo build --release --target riscv64gc-unknown-linux-gnu
ENTRYPOINT [ "/bin/bash" ]
```
Way simpler than everything else, sometimes it's all about installing one package that does the job.
## Running Reth <a name="running-reth"></a>
The last step is to copy the binary built inside the Docker image to the RISC-V VM:
```bash
docker cp <containerId>:/build/target/riscv64gc-unknown-linux-gnu/release/reth .
scp -P 2222 reth root@localhost:/tmp
ssh root@localhost -p 2222
# ...
# ...
# ...
root@debian:~# cd /tmp
root@debian:/tmp# ls
reth
root@debian:/tmp# ./reth node --full
2024-06-24T20:00:40.554366Z INFO Initialized tracing, debug log directory: /root/.cache/reth/logs/mainnet

```
While it is definitely NOT an environnement suited for production, it works!
## Conclusion <a name="conclusion"></a>
We managed to overcome some challenges to build and run Reth on RISC-V, which contributes to maximizing the diversity of the Ethereum infrastructure!
Now let's not celebrate too much: RISC-V is VERY early, slow and insecure (even MDBX reminds us of this, look back at the logs ^^). It's just a proof of concept and also a good excuse for us to test new things.
We also did not (but it's in the TODO list) synchronized a full-node entirely, and therefore can not attest that it works completely.
I really encourage you to try this on your own, hopefully you'll learn a few things in the process. I spent some time reading documentation on RISC-V, the Rust bindgen, cross-compilation and many more. As everyone has it's own way of approaching this deep-focus phase, I'll let you invest your time as you wish.

## what is stock market
You can invest our money in various of company and as per your intrest you can buy and sell shares in market with a proper research and analysis. Other wise they may loose money
## how to buy stocks
To buy and sell stocks we need a demat account and we need to take that demat account under SEBI register comapany only other wise we may face concequence ex:-FYERS,ZERODHA,ANGEL ONE, MOTHI OSWAL,
## HOW STOCK MARKET WORKS(** THE INTERNAL PROCESS**)
If you want to buy a share we cnat go directly to the company and can't ask for shares it is big process so to handle this we have exchanges name it's self exchange stocks they are NSE and BSE.
1. Consider a company like infosys they tieup with a banks and nse or bse they try to list some of there company shares in exchanges
2. Now as i said before we need a demat account to buy those share here intermediates are exchanges(nse,bse) and brokers like angelone.
3.Those will be store in demat account in 2 working days.
## what is bull market and bear market
- In a bull market is liked by retail investors most but we need to be caution when will be end we dont know.
- In a bear market look like blood in dalal street.in that time even a good stocks will fall .And this is actually a good time to invest for future in sip.
## TYPES OF INVESTORS
1. FILLS(out of india like morgan stanly,bank of america)
they will control our market before 2020
2.DILLS (it is noting but our money like FD,bonds,and mutual funds**)
3.HIS also called as big players (like harshath mahatha)
4.retail investors (small investors but now controlling market)
## conclusion :- You may feel regret to miss bitcoin but your grand children will feel regret why my grandpa did't invest in "indian"stock market.

1,904,237 | Accelerated Integration: How We Met Our Deadline Ahead of Schedule. | Introduction: This story or blog is about an Journey of an Integration project. I am sure that today... | 0 | 2024-06-28T16:37:54 | https://dev.to/vaibhav9017/accelerated-integration-how-we-met-our-deadline-ahead-of-schedule-57fl | acceleratedintegration, teamwork, rapiddevelopment, deadlinedriven | **Introduction**: This story or blog is about an Journey of an Integration project. I am sure that today everyone is aware about Integration. What it is? right? But still, let me highlight the thing what is an Integration. In simple words or for better understanding, Integration is nothing but an communication or passing data between two systems through one communication channel.
Similarly as mentioned in above definition, we had one project to integrate Salesforce with WordPress. I won't provide you the details about project itself - thats a story for another time.
In today's world of technology, things can change very quickly. Recently, we faced a big challenge: the deadline of our ongoing project was moved up. Earlier it was different and based on that deadline the progress is going on, however suddenly it gets changed from Client's end. With this change, we found that we don't have much time to complete our tasks. Our tasks was to integrate Salesforce with WordPress. In short its a two way integration, it means data will flow from Salesforce to WordPress and vice versa, both are the crucial systems for client.
The project was going smooth but suddenly we came in trouble, I am not even aware about How to handle this situation. It was very challenging and tough situation for us. I had reached out to our Manager and then after discussion, revising next flow and current state of project we got more resources for that project and target to achieve the end goal. You might think this resolve our issue, that we got resource we can complete the project and meet the deadline, but its not so easy! here! "actually problem starts"... The project was partially build and we got new resource working on that project. Our main aim to meet the deadline, but now with new resources challenge is increased "to make each team member productive from day one." Here's how we did it!
**The Challenge**
Our project was originally planned and to be completed in several months. This actually gives us enough time to carefully perform development and complete integration between Salesforce and WordPress. However, suddenly the deadlines was changed, we had to deliver the project much sooner than expected.
**Solution**
**Expanding the Team**
Our first step was to bring in new resources or team members. This wasn't just about having more hands on deck; it was about having right skills and ensuring everyone could hit the ground running. Everyone is much focused and with confident; as all team members are important and valuable asset for us.
**_How we achieved the speed, lets read below_**
**Getteing Everyone Up to Speed**
To make sure each and every team member should be productive from day one joined the team, we took several steps as below.
- **Clear Communication:** We make sure that everyone should understand the project flow, project goals, their roles and important one that is new timeline. This actually helped to align everone's efforts.
- **Design Diagram:** We have prepared Architectural design diagram of project, and that was iterated to small unit level as well. Once member joined we are providing that diagram and explaining project over it. It actually helps team member lot rather than reading project documentations.
- **Mentorship Communication:** We paired new team member with experienced one, experienced one means the person working since long on that project. This not only worked with quick learning but also build a collaborative team culture.
- **DSM:** Everyone is aware about DSM. We also held daily standup meetings to track the progress and address any issue immediately. This kept everyone one the same page and also allowed for quick adjustments. This also gives us clear picture about today's output.
- **Daily Check-in/Unit testing:**
We also have implemented an unit test case suite in Postman, once we made check in any code over test environment we are running our test suite. It gives clear idea about everything going over production server is errorless.
**- Reporting:** Each day, we are reporting back to our stakeholders, detailing the tasks we had completed. This ensures transparency and kept everyone informed about our progress.
**The Outcome / Result:**
By focusing on above key areas, we turned a potential crises into a success story. The expanded team worked efficiently, confidently and we met the new deadline without compromising on quality. The integration of WooCommerce and Salesforce was completed smoothly.
**What we learned:**
Below are some key takeaway from this experience:
1. **Become Flexible:** Being able to adapt quickly to changing circumstances crucial.
2. **Teamwork:** A well coordinated team can achieve great results, even under pressure.
3. **Preparation:** Having a solid onboarding process can make a big difference in how quickly new team members become productinve.
4. **Communication:** Regular updates and clear communication are vital to keep the project on track.
Accelerated Integration is challenging, but with right approach, its possible to turn it into an opportunity for success. By expanding our team, ensuring everyone was productive from the start, and maintaining clear communication through daily reports, we were able to meet our tight deadlines and deliver high-quality integration of Salesforce and WordPress.

1,904,492 | How to Use Predictive Maintenance for Construction Equipment | Explore the transformative potential of predictive maintenance in construction, ensuring equipment efficiency and minimizing downtime. | 0 | 2024-06-28T16:36:19 | https://www.govcon.me/blog/how_to_use_predictive_maintenance_for_construction_equipment | predictivemaintenance, constructiontechnology, innovation | # How to Use Predictive Maintenance for Construction Equipment
Welcome to the future of construction technology! Predictive maintenance is revolutionizing the industry by maximizing equipment uptime and minimizing costly failures. Buckle up as we dive into how you can leverage this cutting-edge technology to keep your construction projects running smoothly and efficiently.
## What is Predictive Maintenance?
Predictive maintenance (PdM) involves using data analysis tools and techniques to detect anomalies in your equipment's performance. By anticipating issues before they become serious problems, you can perform maintenance activities precisely when needed. This not only extends the life of your machinery but also significantly reduces downtime.
### The Key Components
To effectively implement predictive maintenance, it’s crucial to understand its three core components:
1. **Data Collection**: Sensors installed on construction equipment continuously monitor various parameters like temperature, vibration, and oil condition.
2. **Data Analysis**: Advanced algorithms and machine learning models analyze the collected data to identify patterns indicative of future failures.
3. **Actionable Insights**: The analysis provides actionable insights that inform when and what type of maintenance needs to be performed.
## Benefits of Predictive Maintenance
Predictive maintenance offers a myriad of benefits that can propel your construction projects to new heights:
- **Reduced Downtime**: By predicting equipment failures before they occur, you can schedule maintenance during non-critical times, thereby reducing downtime.
- **Cost Savings**: Avoiding unexpected breakdowns minimizes repair costs and extends the life of your equipment.
- **Improved Safety**: Regular maintenance ensures machinery operates safely, thus minimizing the risk of accidents.
- **Optimized Resource Allocation**: Maintenance can be planned more effectively, allowing for better allocation of labor and resources.
## How to Implement Predictive Maintenance
Implementing predictive maintenance in your construction operations involves a few critical steps:
### Step 1: Sensor Installation
Equip your machinery with IoT (Internet of Things) sensors. These sensors will monitor key parameters such as:
- **Vibration Analysis**: Changes in vibration patterns can indicate mechanical issues.
- **Thermal Imaging**: Infrared sensors detect overheating components that may fail.
- **Oil Analysis**: Sensors monitor the condition of oil for signs of contamination or wear.
### Step 2: Data Connectivity
Ensure all sensors are connected to a centralized cloud-based system. This allows for real-time data transmission and remote monitoring.
### Step 3: Data Analytics
Use advanced analytics platforms powered by AI and machine learning to process and analyze the data. These platforms can identify anomalies and predict potential failure points. Common tools and services include:
- **AWS IoT Analytics**
- **IBM Maximo**
- **Microsoft Azure IoT Suite**
### Step 4: Maintenance Scheduling
Integrate your data analytics with a Computerized Maintenance Management System (CMMS). This helps in creating a predictive maintenance schedule. Tools like **SAP PM** and **UpKeep** can be highly effective.
## Challenges and Considerations
While the benefits are numerous, implementing predictive maintenance isn't without its challenges:
- **Initial Costs**: The upfront investment in sensors and analytics platforms can be significant.
- **Data Overload**: Collecting vast amounts of data can be overwhelming. It's essential to have a robust data management strategy.
- **Skilled Personnel**: You'll need skilled technicians capable of interpreting the data and making informed decisions.
## Real-World Success Stories
Several industry leaders have already reaped the benefits of predictive maintenance:
- **Caterpillar**: By using predictive analytics, Caterpillar has significantly reduced maintenance costs and equipment downtime for their clients.
- **Komatsu**: This heavy equipment manufacturer uses IoT and AI to predict machinery failures, improving their service efficiencies.
## Conclusion
Predictive maintenance is not just a buzzword; it's a game-changer in the world of construction. By harnessing the power of data, IoT, and AI, you can keep your equipment running at peak efficiency, minimize downtime, and drive your projects to success. So, why wait?

1,904,490 | God Explained With Math | How God is the origin we are all expressions of One! | 0 | 2024-06-28T16:34:06 | https://www.rics-notebook.com/blog/Personal/GodUniverse | esoteric, consciousness, meditation, alchemy | ## 🌌 God as the Origin: Expressions and the Universe
### The Origin of All
In esoteric philosophy, God is often seen as the origin and the starting point of everything. This perspective sees God as the fundamental source from which all existence emanates. The universe, in this view, is a manifestation of God's infinite potential, encompassing all of space and time, and all possibilities within them.
### The Universe: Infinite Possibilities
The universe is not just a collection of stars and planets; it is the totality of all that exists, seen and unseen. It represents everything God could choose to be. This infinite space is filled with potentialities, each an expression of the divine will and creativity.
### Human Beings: Divine Expressions
We, as human beings, are seen as expressions of God. Each individual is a unique manifestation of divine essence, contributing to the diversity and richness of the universe. The concept of oneness suggests that everything is interconnected and part of a greater whole, meaning that our existence and actions are intimately linked with the divine and the cosmos.
### Interconnectedness and Oneness
The idea of interconnectedness highlights the intricate relationships between all beings and phenomena. In this interconnected web, nothing exists in isolation; every action and event reverberates through the entire universe, affecting all other parts. This interconnectedness is a reflection of the divine oneness, suggesting that at the deepest level, all is one and all is God.
### Divinity in All
The notion of divinity in all reflects the belief that every aspect of creation contains a spark of the divine essence. This idea is central to many spiritual traditions, which teach that recognizing and honoring the divine within ourselves and others is key to spiritual awakening and enlightenment.
## 🎥 Visualizing the Concept
To further explore and visualize these concepts, you can watch the following animation. It delves into the idea that God is the origin, the universe is the totality of all possible spaces, and we are expressions of God.
[](https://youtu.be/Wfg-IZeRML8)
In this animation, we explore the idea that God is the origin and the starting point of everything. The universe, represented by the circular space, encompasses all of existence as we know it. Within this universe, we are all expressions and functions of God, emanating from the divine origin. The concept of oneness suggests that everything is interconnected and part of a greater whole. The idea of interconnectedness highlights the intricate relationships between all beings and phenomena. Lastly, the notion of divinity in all reflects the belief that every aspect of creation contains a spark of the divine essence.
## The Cosmic Dance: Flux and Reflux
Imagine the whole universe as one big, never-ending dance! Everything in existence is constantly moving and changing, just like dancers on a stage. This continuous movement is called the flux.
The flux is like when the dancers move outward from the center of the stage, expressing their creativity and bringing new shapes and forms to life with their movements. In the same way, the flux represents the outward flow of divine energy, the creative force that brings forth all the amazing diversity we see in the universe – from stars and galaxies to plants, animals, and every single one of us!
Just as the dancers can't move outward forever, there's also a reflux in this cosmic dance. The reflux is like when the dancers move back towards the center of the stage, coming together in unity. It's the inward movement of all creation, where individual expressions ultimately merge back into the oneness of the divine source, like different colors blending into one.
This eternal dance between the flux (outward movement) and the reflux (inward movement) is the rhythm of the cosmos, the very heartbeat of existence. It's like the dancers constantly moving outward to express their creativity, and then coming back together in harmony.
In mathematics and science, we can see similar patterns of flux and reflux. For example, in the study of waves, there's the outward flow of energy (like the crest of a wave), and then the inward flow (like the trough of a wave). Or in the study of cycles, there's the outward expansion phase and the inward contraction phase, which repeats over and over again.
By aligning our intentions and actions with this cosmic dance, we can move in sync with the fundamental currents of life itself. Whether through prayer, meditation, service, or any other spiritual practice, the essence lies in attuning ourselves to the flux and reflux, just like dancers attuning themselves to the music and rhythm.
When we move in harmony with the outward and inward tides of divine energy, we find ourselves carried by the wind at our backs, propelled towards our highest aspirations and deepest fulfillment, just like dancers gliding gracefully across the stage.
All authentic spiritual paths, though diverse in their methods, ultimately aim to help us consciously participate in this dance of creation and dissolution, unity and diversity, the eternal play of the one infinite reality.
## The Divine Unity: All Paths Lead to the Source
In recognizing the interconnectedness and oneness inherent in the universe, we can appreciate the validity of diverse spiritual traditions and practices. Though expressed through different lenses, mythologies, and rituals, all authentic spiritual paths are ultimately striving towards the same goal – union with the divine essence.
Just as a multitude of rivers eventually merge into the vast ocean, the myriad religions and spiritual teachings are like streams flowing towards the ultimate reality of God or the absolute source. Each tradition offers a unique perspective and method tailored to the cultural, historical and geographical contexts from which it emerged. Yet, at their core, they all point towards the realization of our true nature as expressions of the divine.
This understanding allows us to transcend divisive dogmas and doctrinal conflicts. We can honor the sacred wisdom carried within various faiths, recognizing that they are complementary avenues for experiencing the infinite beauty, love, and truth that pervades all of existence.
Whether through prayer, meditation, selfless service, or conscious living, every sincere spiritual seeker is essentially undertaking a journey of remembrance – rediscovering their intrinsic connection to the source and its infinite potentialities. This realization liberates one from the confines of the separate self, enabling a state of unity, peace, and reverence for all life.
In this light, adherents of various religions need not perceive themselves as being in conflict or competition. Rather, they can celebrate the wondrous diversity through which the one divine reality is expressed and experienced. For the sincere seeker, all paths are sacred and valid, ultimately leading towards the same transcendent realization – union with the origin of all. | eric_dequ |

1,630,497 | React Hydration explained | If you are a frontend developer and have some experience with React, you may have heard the term... | 0 | 2024-06-28T16:27:37 | https://dev.to/saeedmosavat/react-hydration-explained-egh | react, javascript, webdev, frontend | If you are a frontend developer and have some experience with React, you may have heard the term "Hydration". In this article we will explore what it is, why we need it and how it works.
This is what the official react [documentation](https://react.dev/reference/react-dom/hydrate#:~:text=In%20React%2C%20%E2%80%9Chydration%E2%80%9D%20is,the%20app%20on%20the%20client.) says about hydration:
>In React, “hydration” is how React “attaches” to existing HTML that was already rendered by React on a server environment. During hydration, React will attempt to attach event listeners to the existing markup and take over rendering the app on the client.
"React on the server", you may wonder! "Wasn't react a client-side thing?"
Well, not anymore. This is 2024 and we even have Server Components now (how crazy is that?!)
There is a lot of things going on in this definition that we will cover in this post. Let's start with **why** and **how** react is rendered on the server.
## React on the server
Traditionally, a react application is a tiny HTML with a giant JavaScript including react code itself and the application code that uses react. when this JavaScript runs, it will populate the HTML with some meaningful and interactive content (our app).
```html
<html>
<head>
<title>React App</title>
<script src="the/giant/app.bundle.js" ></script>
</head>
<body>
<div id="root"></div>
</body>
</html>
```
We can send this tiny HTML to the users, their browser will download and run the JavaScript code, which will populate that "root" div element and then they'll have the running application. No matter what page the user is looking for, it can always start from the same HTML above. This is actually how Create React App works.
There are two things to consider:
- Every time a user opens our website, they will see a blank page followed by a spinner for a while. The blank page is not surprising because we have sent them an empty HTML! But even after receiving that HTML, it takes some time to download the js files (still showing a blank page) and even when js files are downloaded and our application runs, it usually needs some data from the server to show the page content, so we show spinners while waiting for that data. It kinda sucks, right?
- Humans are not the only users of our websites, robots are visiting too. Like the Google Bot.
But unfortunately, robots have more work to do than humans and they will not wait for our stupid spinners to finish. (Well actually sometimes they do, but they do it later in a "less busy" time and we don't want to rely on that).
So, in order to keep both humans and robots happy about our website, we should give them the real HTML they are looking for the moment they request a page. Just like the good old-fashioned websites. And since our application is rendered by react, we need a way to "pre-render" the app on the server to get that HTML.
For simplicity let's imagine our App only has one page (so we can ignore "routing" on the server) and this is the corresponding component:
```jsx
const App = () => {
const [product, setProduct] = useState(null);
const [isLoading, setIsLoading] = useState(true);
useEffect(() => {
fetch("/product")
.then((res) => res.json())
.then((data) => setProduct(data))
.finally(() => setIsLoading(false));
}, []);
if (isLoading) {
return <div>Loading...</div>;
}
return <div>{product.name}</div>;
};
```
So, we need to run our react App on the server to get the final HTML that the user wants to see and then return that HTML as the response to the clients request for the page.
React provides a `renderToString` method specifically for this purpose. All we have to do is to pass it the JSX element for the root of our App and get the rendered app as HTML. then we can send back this HTML to the client:
```jsx
import { renderToString } from 'react-dom/server';
const html = renderToString(<App />);
```
But, there is a small problem. Our app calls an asynchronous API to fetch the data and render something meaningful. However, there is no way for react's `renderToString` method to know this logic and to know how much it should wait for the App to finish all data fetches and re-renders until the final meaningful content is rendered. So it just lets the app to render **once** and before executing any `useEffects` or re-renders, it returns the resulting HTML. Oops!
In our example the result will be something like this:
```html
<html>
<body>
<div id="root">
<div>Loading...</div>
</div>
</body>
</html>
```
This is obviously not desired. The solution to this is to provide the data that is needed for the App at the time we want to render the App. So we have to make some slight improvements:
```jsx
const App = (props) => {
const [product, setProduct] = useState(props.initialProduct);
const isInitialized = !!props.initialProduct;
const [isLoading, setIsLoading] = useState(!isInitialized);
useEffect(() => {
if(!isInitialized) {
fetch("/product")
.then((res) => res.json())
.then((data) => setProduct(data))
.finally(() => setIsLoading(false));
}
}, [isInitialized]);
if (isLoading) {
return <div>Loading...</div>;
}
return <div>{product.name}</div>;
};
```
```jsx
const response = await fetch("/product");
const data = await response.json();
const html = renderToString(<App initialProduct={data}/>);
```
And now we get the correct HTML that shows the product details.
## Back to the client
So far the client has received the content-full HTML, along with the js files to run the react app. Robots are happy now, but it's not the case for our human users because React is not happy! When React loads, it tries to render the `<App>` and create something called "[Virtual DOM](https://legacy.reactjs.org/docs/faq-internals.html#what-is-the-virtual-dom)" (just think of it as a copy of the page document, managed by react). Virtual DOM is the single source of truth for React and all its changes will be reflected on the browser DOM. so it has to make sure the browser DOM matches the virtual DOM to begin with. But in our example, react app has started with a loading state in the first render on the client (because here we don't have any value to pass to `<App>` as `initialPrduct` prop) while the browser DOM has the product details. React has to get rid of anything that it doesn't acknowledge in the document, so it removes the page and shows the loading state again! We are back to square one!
##Dehydration to rescue
To address the above issue and prevent a loading state on the client and keeping the already fetched data on the page, we should somehow transfer the fetched data on the server to the client. This way the client has everything it needs to take over the rendering of the App that has started on the server.
What if We could send the server data in a JSON string alongside the rendered HTML. Let's assume the server has put this script in the HTML:
```html
<script>
window._data = '{ "id": 1, "name": "some product name" }';
</script>
```
We can then use it to bootstrap the app like this:
```jsx
// index.jsx
const dataFromServer = JSON.parse(window._data);
ReactDOM.render(
<App initialProduct={dataFromServer} />
document.getElementById("root")
);
```
This process of sending the data required for hydration from server to client is called **dehydrarion**. Frameworks like Next.js handle this process seamlessly for you. You can inspect the `window.__NEXT_DATA__.props` object in the console of a Next.js website to see it in action.
##Conclusion
In summary, hydration is a crucial process in React applications that allows for a seamless transition between server-rendered HTML and the fully interactive client-side application. By sending the necessary data alongside the initial HTML, we can avoid an unnecessary loading state on the client and ensure a smooth user experience. This approach improves initial load times, enhances SEO, and provides a more responsive application for users.

Welcome to the future: a place where **laser scanning technology** revolutionizes how we plan, execute, and monitor construction projects. In this post, we will delve into the exciting world of laser scanning, exploring its incredible accuracy, efficiency, and how it can be integrated into your construction workflow.
## What is Laser Scanning?
Laser scanning, also known as **LiDAR** (Light Detection and Ranging), is a method that captures detailed 3D data by illuminating the target with laser light and measuring the time it takes for the light to bounce back. The result is a highly accurate, detailed representation of the surveyed area.
## Advantages of Laser Scanning in Construction
### Precision and Accuracy
With traditional surveying methods, human error is a significant concern. Laser scanners, on the other hand, offer millimeter-level precision, drastically reducing the risk of mistakes. This accuracy is crucial when dealing with complex structures or tight urban environments.
### Time Efficiency
Speed is of the essence in any construction project. Laser scanners can survey extensive areas in a fraction of the time it would take with traditional methods. This reduced survey time translates into quicker project completion and, ultimately, cost savings.
### Comprehensive Data Collection
Laser scanners can capture millions of data points per second, resulting in a **point cloud**—a dense, 3D representation of the scanned environment. This comprehensive data allows for better planning, visualization, and even virtual walkthroughs of the project site.
## How Does Laser Scanning Work?
### Equipment Selection
First things first: choose the right scanner. Options range from hand-held devices for small projects to tripod-mounted and vehicle-mounted scanners for larger, more complex environments. Leading brands include **Leica**, **Trimble**, and **Faro**.
### Setting Up
Set up your scanner at strategic locations around the area to be measured. Ensure the location provides a clear line of sight and minimal obstructions to maximize data accuracy.
### Scanning Process
Once set up, the scanning process begins. The laser device will rotate and shoot beams of light across the scanning area, capturing every surface it encounters. The scanner's software algorithms will stitch together these points to form the final 3D model.
### Data Processing
After scanning, the raw point cloud data needs to be processed. Software like **AutoCAD**, **ReCap**, and **Pointfuse** can transform raw point clouds into usable models and blueprints. These tools allow you to clean up the data, remove redundancies, and convert it into formats that can be used in CAD applications.
## Integrating Laser Scanning Data into Construction Workflow
### Planning and Design
Utilize the 3D models generated from laser scans to enhance your planning and design stages. Visualization of the project in its context will help in identifying potential issues and making informed decisions early in the project lifecycle.
### Quality Control
Laser scanning can be an invaluable tool for quality control. Conduct regular scans throughout the construction process to ensure the project stays true to the design specifications. Any deviations can be quickly spotted and corrected.
### Documentation
Laser scans provide an indisputable record of existing conditions before, during, and after construction. This historical record is valuable for future renovations, compliance with regulations, and resolving disputes.
## Future Trends in Laser Scanning Technology
### Integration with BIM
Building Information Modeling (BIM) and laser scanning are a match made in heaven. The point cloud data from scans can be integrated directly into BIM software, providing a robust digital twin of the physical space.
### Mobile and UAV Scanning
The advancement of mobile laser scanning units and UAV (Unmanned Aerial Vehicle) or drone-based scanners expands the reach of this technology. This allows for the quick and safe scanning of hard-to-reach or hazardous areas.
### Real-Time Scanning
As processing power and algorithms improve, real-time scanning and processing are becoming possible. This would enable immediate feedback and on-the-fly adjustments during construction, leading to even greater efficiency.
## Conclusion
Laser scanning technology is undeniably transforming the construction landscape. Its unmatched precision, efficiency, and comprehensive data collection capabilities make it an invaluable asset.

In the traditional way of... | 0 | 2024-06-28T16:14:18 | https://dev.to/ak_15/40-days-of-kubernetes-docker-fundamentals-193c | docker, fundamentals, kubernetes, cka | To understand Kubernetes, we should understand the concept of containers.
In the traditional way of development, the application deployment in local environments such as development and testing worked fine but would fail when promoted to production. The **"it works on my machine"** problem was never-ending.
When analyzed, the reasons behind the failure were mostly due to environment misconfigurations and missing dependencies or libraries etc.
To solve this problem, we use **containers**
What are containers?
Containers are packages of software providing an isolated environment with all the necessary libraries, dependencies, application code, and the operating system required to run an application making sure that the application is running in the same way irrespective of the host operating system. The purpose of containers is to build-ship-run the code.
Unlike virtual machines, which has its own Infrastructure, OS, binaries, dependencies of its own where the chance of resources being underutilized are very high; Containers are lightweight environments that include only the required components that is required by the application. Containers are isolated but they share some of the resources and infrastructure of the host.
**Docker** is a platform that carries out containerization by building, running and shipping the tasks.
**Docker File**: A set of instructions that are required for building docker image.
**Docker Image**: Its a template packaged with necessary software's and dependencies.
**Docker Container**: It's a running instance of a Docker image.
The Key commands of Docker are:
- _docker build_: This command builds a Docker image based on the Docker file.
- _docker push_: This command pushes the created image to a Docker registry.
- _docker pull_: This command is used to pull the image from the registry to the desired environment.
- _docker run_: This command creates and runs a container from the pulled image.
**Docker Architecture:**
**Docker Client** is the interface using which users interact with Docker.
**Docker Daemon (DockerD):** All the commands issued by the docker client are received and executed by Docker daemon. It is the most important service that runs in the background managing the containers.
**Docker Host:** It is a component of docker architecture that is responsible for running one or more containers.
**Docker Registry:** A Docker registry is a storage for Docker images. They can be pushed to a registry before deploying them to various environments.
**Container Runtime:** The component that is responsible for running containers.
When a client request is sent to Docker Daemon, it interacts with container runtime to build an image based on Dockerfile and then the image is pushed to Docker registry and pulled from it when required.
We will learn in the next step to create a Dockerfile, build an image, and execute our first containerized application.

1,904,479 | How Next router handles routing differently from React Router Dom | React and Next.js are similar in some ways, and different in others. One of those differences is in... | 0 | 2024-06-28T16:22:32 | https://dev.to/armstrong2035/how-next-router-handles-routing-differently-from-react-router-dom-o40 | **React** and **Next.js** are similar in some ways, and different in others. One of those differences is in how both frameworks handle routing. As someone who has used React for most of my career, I was surprised to find how different Next.js routing is from React Routing. Understanding these differences is crucial for developers working with either framework. I will continue to update this article as I learn more about Next routing. But for now, this article will cover the following:
- Declarative vs file-based routing
- Dynamic routing
Before we dive in, it's important to note that routing in React is typically done with **React Router Dom**, an external library. Next.js, however, has its inbuilt routing capabilities.
Also, this article is written for the [HNG internship](https://hng.tech/internship). It is a three-month-long program where new developers can test themselves. They also offer career services such as recruitment and mentorship. More details [here](https://hng.tech/premium)
Okay, let's explore these differences in detail.
## Declarative vs File-Based Routing
The first major difference between routing in React and Next.js is how routing is handled.
### React Routing
In React, we need to:
1. Add **BrowserRouter** to `index.js`
2. Declare the **Routes** component
3. Nest each **Route** component inside **Routes**
4. Add the intended component we want to route to, and the URL to each **Route** component
Here's an example:
```jsx
// index.js
ReactDOM.render(
<BrowserRouter>
<App />
</BrowserRouter>,
document.getElementById('root')
);
// App.js
const App = () => {
return (
<div>
<Routes>
<Route path="/" element={<Home />} />
<Route path="/about" element={<About />} />
<Route path="/blog" element={<Blog />} />
<Route path="/blog/:id" element={<BlogPost />} />
</Routes>
</div>
);
};
export default App;
```
In summary, you have to define each route in React explicitly.
### Next.js Routing
Next.js uses a different paradigm. You don't have to define routes explicitly due to Next's file-based routing, which uses the path of the file where your component is located as the URL of that route.
Using the same example as we used for React, our routes in Next.js might look like this:
```
my-next-app/
├── pages/
│ ├── index.js // Corresponds to "/"
│ ├── about.js // Corresponds to "/about"
│ ├── blog/
│ │ ├── index.js // Corresponds to "/blog"
│ │ └── [id].js // Corresponds to "/blog/[id]"
├── components/
│ ├── Home.js // Component used in pages/index.js
│ ├── About.js // Component used in pages/about.js
│ ├── Blog.js // Component used in pages/blog/index.js
│ ├── BlogPost.js // Component used in pages/blog/[id].js
└── public/
└── ...
```
Next.js chose this file-based routing approach to simplify the routing process and make it more intuitive. It eliminates the need for a separate routing configuration, reducing boilerplate code and making the project structure more straightforward. This approach aligns well with Next.js's goal of providing a more opinionated and streamlined development experience.
In Next.js, we write our JSX inside `About.js` and then render it inside its route, `about.js`. This introduces an important design pattern when using Next.js - separating concerns:
```jsx
// pages/about.js
import About from '../components/About';
export default function AboutPage() {
return <About />;
}
// components/About.js
import React from 'react';
const About = () => {
return <h1>About Page</h1>;
};
export default About;
```
In summary, Next.js routes are defined based on the component tree and the respective paths.
## Dynamic Routing
The declarative approach of React Router and the file-based approach of Next.js impact how dynamic routes are built and executed in both frameworks.
### Dynamic Routing in React
In React, you can define a dynamic route by adding a colon to the route URL:
```jsx
// App.js
const App = () => {
return (
<div>
<Routes>
<Route path="/blog" element={<Blog />} />
<Route path="/blog/:id" element={<BlogPost />} />
</Routes>
</div>
);
};
export default App;
```
Each blog has a unique URL, so the path is `/blog/whatever-the-title-of-the-blog-is`.
Here's how you would use the dynamic parameter in React:
```jsx
import { useParams } from 'react-router-dom';
const BlogPost = () => {
const { id } = useParams();
return (
<div>
<h1>Blog Post {id}</h1>
{/* Use the id to fetch and display the blog post */}
</div>
);
};
export default BlogPost;
```
### Dynamic Routing in Next.js
Next.js handles dynamic routing differently:
```
├── pages/
│ ├── blog/ // Corresponds to "/blog"
│ │ └── [id].js // Corresponds to "/blog/[id]"
```
Next.js indicates that a route should be dynamic by putting a variable inside square brackets. Here's how we might configure this:
```jsx
import { useRouter } from 'next/router';
const BlogPost = () => {
const router = useRouter(); // Get the router object
const { id } = router.query; // Destructure to get the 'id' from the URL
return (
<div>
<h1>Blog Post {id}</h1>
{/* Use the id to fetch and display the blog post */}
</div>
);
};
export default BlogPost;
```
Here's what Next.js is doing under the hood:
1. Inside the `[id].js` file, we call the **useRouter()** method. This method reads `[id].js` file and saves it as an object. We save the result inside the `router` variable.
2. Then, we use the `query` function from **useRouter** to extract a specific part of the object that was generated. In this case, we collect the `id`.
3. Next.js will use that `id` collected as the URL for that route.
Let's see how we would link to this route:
```jsx
import Link from 'next/link';
const BlogList = ({ blogs }) => {
return (
<div>
<h1>Blog List</h1>
<ul>
{blogs.map((blog) => (
<li key={blog.id}>
<Link href={`/blog/${blog.id}`}>
<a>{blog.title}</a>
</Link>
</li>
))}
</ul>
</div>
);
};
export default BlogList;
```
We're taking the URL `/blog/[id].js`, and replacing it with `/blog/${blog.id}`. This way, whatever value `blog.id` holds becomes the URL, giving each individual blog its own unique route.
## Conclusion
While both React (with React Router) and Next.js provide powerful routing capabilities, they approach it differently. React Router uses a more declarative style, while Next.js leverages file-based routing. Understanding these differences can help developers choose the right framework for their needs and use routing effectively in their applications. | armstrong2035 | |

It’s... | 0 | 2024-06-28T16:22:27 | https://dev.to/divine-ikechukwu/how-to-overcome-creative-block-as-a-web-designer-50mh | webdesign, design, webdev, productivity |
You know those times when you want to design something but just don’t know how to start? It’s always frustrating, isn’t it? You know you can do it, but your creative juices just aren’t flowing. This often happens after taking a short break from your regular design practice, or when you’re not feeling inspired by anything. So, how do you get past this phase? Because, obviously, you need to get back to producing clean, creative designs at work as quickly as possible. This article is written just for you. We will be looking at:
- The main causes of creative block
- How to get back your creative juices
- Daily habits you can engage in to stay creative
Without further ado, let’s look at the main causes of creative block:
**Feeling Burnt Out**
Not getting enough rest or being inconsistent with your design practice can mess with your creativity. It's always adviceable to make sure you're taking breaks and allowing yourself time to recharge, but not for too long sha.
**Playing It Safe with Design**
Are you designing the same things as every other uncreative, regular designer? I hope not. Well, the fact that you’re reading this suggests you like being creative with your designs. Constantly doing things the same way as others doesn’t make you creative. As my friend Bassey Thomas says, “creativity is limitless,” and I believe that too. Develop a design language of your own. Let people see your design outside and be like, "this is surely Zubi's work.
**Starting Your Design on Screens**
Sketching on paper or starting a project with low-fidelity processes is becoming less common. Many companies now prefer to start with design sprints, perhaps due to the need to meet short deadlines or simply out of convenience. What makes first sketching your ideas so important is that everything is rough and you don’t care. You’re also not afraid of changing anything. This approach creates room for mind exploration.
So now, how can you get back your creative side again?
### Explore Other People’s Creative Designs
As a web designer, one of the fastest way to get inspiration is by looking at fellow designers' work. This may involve visiting websites like Pinterest, Dribbble, or Behance to immerse yourself in creative works on similar subjects and patterns. Once you open Figma and start designing, you might initially hate what you create, but don’t worry. Keep your composure😂 and continue. Rebuilding your creativity takes time, but it will come back.
### Replicate Creative Designs
Constant practice leads to perfection. Training your brain to behave in a certain way it previously used to can help. Engaging with other people’s designs by replicating them is one of the fastest ways to regain your creative juices. This approach is even more effective than just looking at designs. Trust me, after completing at least two full website UI design projects, your creative side will return.
### Change Your Environment
Sometimes, a change of environment can be what you need. This doesn’t necessarily mean taking a vacation or traveling far. Simply stepping out of your home office or exercising in a different place can spark your creativity. Attending art shows or design events can also be a source of inspiration.
**Daily Habits to Stay Creative**
- Exercise
- Practice design daily
- Read design articles
- View other people’s designs
- Take breaks and get some fresh air
- Keep a sketchbook or inspiration board
I think we have reached the end of this piece. Remember: take breaks when you need to, but practice design consistently and always seek inspiration.
Thank you! | divine-ikechukwu |

1,904,469 | How to Use Geofencing for Enhanced Construction Site Security | Discover how geofencing technology can revolutionize security measures on construction sites by offering real-time alerts, precise monitoring, and robust protection. | 0 | 2024-06-28T16:16:04 | https://www.govcon.me/blog/how_to_use_geofencing_for_enhanced_construction_site_security | geofencing, construction, security, technology | # How to Use Geofencing for Enhanced Construction Site Security
In the ever-evolving landscape of construction, the integration of advanced technology is not merely beneficial but essential. Among the myriad of innovative solutions, geofencing stands out as a game-changer in ensuring robust security on construction sites. Imagine a virtual perimeter that not only safeguards your site but also enhances operational efficiency. Intrigued? Let's dive into how geofencing can transform construction site security.
## What is Geofencing?
Geofencing leverages GPS, RFID, Wi-Fi, or cellular data to create a virtual boundary around a physical location. When this virtual perimeter is breached, specific actions are triggered, such as sending alerts or notifications. This technology, which might have seemed like science fiction a few decades ago, is now an accessible and powerful tool for security and operational management.
## Advantages of Geofencing in Construction Security
### **1. Real-Time Alerts and Notifications**
Geofencing allows for instantaneous alerts whenever the virtual boundary is crossed. These alerts can be customized to notify site managers, security personnel, or law enforcement via SMS, email, or specialized apps. It's not just about detecting intruders but about proactive management.
### **2. Enhanced Surveillance Capabilities**
Integrating geofencing with CCTV and drone technology creates a formidable surveillance system. Drones can be deployed automatically to areas where the virtual boundary has been breached, providing real-time video feeds and helping to effectively assess and respond to threats.
### **3. Access Control and Authorization**
By defining geofences around sensitive areas within the site, access can be restricted to authorized personnel only. This ensures that critical equipment and materials are protected from theft or vandalism, and safety is maintained by preventing unauthorized access to hazardous areas.
### **4. Efficient Resource Management**
Beyond security, geofencing helps in tracking the movement of resources and equipment. If an asset is moved beyond its designated area, immediate alerts can be generated, minimizing loss and enabling efficient resource management.
## Implementing Geofencing: Steps to Get Started
### **Step 1: Define Your Zone**
Identify the areas around and within your construction site that require monitoring. This involves recognizing critical points such as entry and exit gates, storage areas for valuable equipment, and zones with high safety risks.
### **Step 2: Choose the Right Technology**
Select the appropriate geofencing technology based on your needs. GPS-based geofencing is excellent for outdoor sites, while RFID and Wi-Fi-based systems work well for indoor applications. Ensure the system is compatible with your existing security infrastructure.
### **Step 3: Integration with Existing Systems**
Integrate your geofencing solution with current security measures, including surveillance cameras, access control systems, and monitoring software. This unified approach ensures a seamless security operation.
### **Step 4: Customize Alerts and Responses**
Set up customized alerts and define the response protocols. Who gets notified? What steps should be taken once a breach is detected? For example, if expensive machinery is moved outside the authorized zone during non-working hours, an alert can be sent to the site manager and security team simultaneously.
### **Step 5: Train Your Team**
Inform and train your team on the new system. Ensuring that everyone understands how geofencing works, the types of alerts they might receive, and the protocols for responding to those alerts is crucial for effective implementation.
## Case Study: Real-World Application
Consider a large-scale construction project undertaken by a leading multinational firm. By deploying a combination of GPS-based geofencing and RFID tags, they managed to reduce equipment theft by 75% over six months. Real-time alerts allowed immediate responses to unauthorized access, while integrated surveillance provided actionable insights for on-ground personnel.
## Future Prospects
The potential of geofencing in construction security is immense and continually evolving. Integration with AI can predict and alert about potential breaches before they happen by analyzing patterns. Furthermore, as IoT devices become more prevalent, interconnected systems can provide even more fine-grained control and efficiency.
## Conclusion
Geofencing is more than just a security measure; it’s a technological advancement that offers peace of mind while enhancing productivity. By harnessing the power of geofencing, construction sites can operate safely, securely, and efficiently, paving the way for a future where technology and construction seamlessly blend.

1,904,425 | My Journey as a Backend Developer: Tackling AI-Powered Sentiment Analysis for Course Reviews | INTRODUCTION My name is Adekolu Samuel Oluwaseun, an undergraduate student of Veritas... | 0 | 2024-06-28T16:14:51 | https://dev.to/samixx_yasuke/my-journey-as-a-backend-developer-tackling-ai-powered-sentiment-analysis-for-course-reviews-4doi | webdev, javascript, programming, node | ## INTRODUCTION
My name is Adekolu Samuel Oluwaseun, an undergraduate student of Veritas University Abuja studying Computer Science and Information Technology. I want to open up my journey as I talk about one of the most difficult backend projects I've worked on which I used as my final year project. But before that I'll like to say a little about myself, Python was one of the first programming language I learned, but I wasted a lot of time by not writing at an especially high volume. I had my first serious programming experience during the 6-month SIWES in 2023. While the organization I worked with as an intern (AUDA NEPAD) was not tech-focused, a friend by the name Mercy gave me her course from Udemy.The course which was taught by one of the best tutors in the tech space by the name Angela Yu was for HTML, CSS, JavaScript(Node js, Express. js, and more). Keeping up with the learning was a struggle but I kept going and attempted some more Frontend Mentor challenges to see how far i had come.
One Year year later, in 2024, I think I'll consider myself an intern-level developer looking to get hands on experience and wanting to be amongst other developers. So i registered for the HNG 11 internship even though I am an introvert and a person that cannot stay out of my comfort zone as it is very difficult to do but with advice from some friends and dad, I decided to go into this. One of my primary goal during the HNG internship is to work on projects where real-world impact can be seen and network in the right circles.
Now that you guys have an Idea about me let's talk about the backend project that pushed me to my limit.
## Building an AI-Powered Sentiment Analysis System
I have found one of the toughest projects to be my Final Year Project where I had built this AI-based Aspect Based Sentiment Analysis tool for course reviews. It aimed to invite students express course feedback in natural language, while the AI divides the content into seven categories and score sentiment (positive/ negative / neutral) respectively.
Initial Planning
I first came up with these requirements:
Student Route:
- Matric authentication with password.
- View submitted course forms.
- View course forms those not submitted
- Make reviews.
University Route:
- Create course review forms.
- Change form visibility.
- Update/delete forms.
- University Authentication
- View general reviews.
## 1. Implementing the Solution
Initially, I planned to handle authentication for both students and universities. However, after researching, I decided to manage authentication on the frontend using an authentication service called Auth0. This simplified the backend by removing the need for separate authentication routes for students and universities. Users authenticate via email/password or Google, receiving a unique ID stored in my database to identify them.
## 2. AI Model and Sentiment Analysis
My original plan was to fine-tune a BERT model using Python. However, due to my limited Python skills, I decided to use OpenAI's GPT-3.5 model. I sourced course review datasets from Hugging Face and created training data in OpenAI's JSONL file format for fine-tuning. The dataset can be accessed [here](https://huggingface.co/datasets/kkotkar1/course-reviews). The fine-tuned model performed well in splitting reviews into aspects and determining their sentiment.
## 3. Database and Schemas
I used MongoDB to store information and the Mongoose Node.js library to interact with the database. I created the following schemas:
- Course Feedback Form Schema
- Student Schema
- University Schema
- Student Feedback Schema
## Workflow
The architecture involves students submitting open-ended course reviews, which are processed by the AI model to extract aspects and sentiments. The results are then stored in the database. Here’s a simplified workflow:
1. Student Authentication: Using Auth0 on the frontend.
2. Review Submission: Students submit reviews.
3. AI Processing: Reviews are processed by the fine-tuned GPT-3.5 model.
4. Database Storage: Processed reviews are stored in MongoDB.
5. University Access: Universities can create, update, and view reviews.
## Final Thoughts
This project taught me a lot about backend development, AI integration, and real-world problem-solving. It was a challenging but rewarding experience that has prepared me for future projects. I'm eager to apply these skills in the HNG Internship, contribute to meaningful projects, and grow as a developer.

1,904,468 | Understanding RAID Levels | A comprehensive guide to understanding the different RAID levels and how they can improve performance, capacity, and fault tolerance of hard disk drives. | 0 | 2024-06-28T16:13:36 | https://www.rics-notebook.com/blog/Networking_priciples/Raid | raid, storage, technology, devops | # Understanding RAID Levels
RAID redundant array of independent disks is a technology that combines
multiple hard disk drives HDDs into a single logical unit. RAID provides
several benefits over using a single HDD, including improved performance,
increased capacity, and improved fault tolerance.
In this guide, we will be discussing the different RAID levels, their advantages
and disadvantages, and help you determine which RAID level is right for you.
## RAID 1 (Mirroring)
RAID 1 involves creating an exact copy of all data on two or more HDDs. This
provides the highest level of fault tolerance, as if one HDD fails, the data can
be recovered from the other HDD. However, RAID 1 has the lowest capacity
utilization, as all data is duplicated.
## RAID 5 (Striping with Parity)
RAID 5 divides data into blocks and stores each block on a different HDD. A
parity bit is also stored on each HDD, which can be used to reconstruct the data
if one HDD fails. RAID 5 provides good fault tolerance and capacity utilization,
but it is not as reliable as RAID 1.
## RAID 6 (Striping with Double Parity)
RAID 6 is similar to RAID 5, but it uses two parity bits per block. This
provides even better fault tolerance than RAID 5, but it also has a lower
capacity utilization.
## RAID 10 (Mirroring and Striping)
RAID 10 is a combination of RAID 1 and RAID 0. It involves creating an exact
copy of each block of data on two HDDs, and the blocks are then striped across
the HDDs. RAID 10 provides the highest level of fault tolerance and capacity
utilization of any RAID level, but it is also the most expensive.
## Choosing the Right RAID Level
The best RAID level for you will depend on your specific needs. If you need the
highest level of fault tolerance, RAID 1 is the best choice. If you need a good
balance of fault tolerance and capacity utilization, RAID 5 or RAID 6 is a good
choice. If you need the highest capacity utilization, RAID 10 is the best
choice.
Remember, no RAID level is 100% reliable. It is always important to have a
backup plan in place for critical data.

1,904,464 | Styled Components vs TailwindCss (UIs Showdown) | As a front-end developer, when it comes to styling user interfaces, two popular options always come... | 0 | 2024-06-28T16:09:58 | https://dev.to/oladee/styled-components-vs-tailwindcss-uis-showdown-2jho | react, css | As a front-end developer, when it comes to styling user interfaces, two popular options always come to mind: Styled Components and Tailwind CSS. Both offer distinct approaches, and the "better" choice depends on your project's specific needs, although I have my preferred option of the two, but lets take on a journey to understand what both styling frameworks have to offer and leave the picking to you!
## STYLED COMPONENTS
Talking about the reuse-ability of components style of thinking and approach, Styled Components embraces a component-centric approach. Styles are encapsulated within JavaScript components, promoting code maintainability. With styled components, css code is specific to the component it is being used for, as this allows for component-specific styling and helps to reduce the problem of unused styling when a component isn't rendered or in use
## TAILWINDCSS
Tailwind tends to lean to the ideology of utility first. Utility first just boils down to styling that does a specific thing, ranging from padding, colour, e.t.c. Tailwind provides a vast amount of predefined utility classes that users could apply directly to their components and dumb the hassle of write css code from scratch.
Here are some key points that seek to delve into the strengths and difference of these frameworks
## Theming
- **Styled Components:**
Offers built-in theming capabilities. You can define themes with variables and easily apply them to styled components for consistent UI styles
- **Tailwindcss** :
Requires customisation of its default theme through configuration files. While effective, it might not be as intuitive as Styled Components' theming approach.
## PERFORMANCE
- **Styled Components:**
Might have a slight overhead due to the runtime manipulation of styles. However, this is generally negligible for most modern web applications.
- **Tailwind CSS:**
Generally considered performant due to its reliance on pre-defined utility classes. However, excessive class usage can lead to larger CSS payloads.
This is great to know, but when really is the best time to choose either of the framework seeing they both offer different approach to solving major styling issues.
1. You're working on a large-scale React project with a focus on reusability and maintainability.( Styled Component preferably)
2. You prefer a utility-first approach with fine-grained control over styles. (Tailwind all the way)
3. You value clear separation of concerns and keeping styles encapsulated within components. (Styled Component)
4. You prioritize a component-based approach to UI development.
(Styled Component)
5. You need a rapid prototyping tool for quick UI development.
(Tailwind)
## Conclusion
Both Styled Components and Tailwind CSS are excellent tools. The best choice depends on your project's specific requirements and team preferences.
Consider Styled Components if you prioritize component-based development, maintainability, and theming in React projects.
Opt for Tailwind CSS if you value rapid prototyping, utility-first styling, and a gentler learning curve, especially for teams with traditional CSS experience.
If you are asking about my preferred option, then it will be Tailwindcss, due to its simplicity and straightforwardness. During my time interning at HNG, i am looking towards using it to build worthwhile projects. Kindly find out more about this using https://hng.tech/internship or https://hng.tech/premium.
This should be fun at its best. Thanks for taking out time to read

2. **Scalability**: As quantum computing technology advances, quantum networks have the potential to scale up to handle increasingly complex tasks and larger volumes of data. 📈🖥️
3. **Applications**: Quantum networks have a wide range of potential applications, from secure communications and financial transactions to distributed sensing and blind quantum computing. 🏦🔍
4. **Integration**: Quantum networks can be integrated with existing classical networks, allowing for a smooth transition and the ability to leverage the strengths of both technologies. 🤝🌐
## Challenges and Future Prospects 🚧
Of course, realizing the full potential of quantum networks is not without its challenges. Researchers are still working on developing reliable quantum hardware, error correction techniques, and standardized protocols for quantum communication. 🔧💡
However, with major tech companies and governments investing heavily in quantum research, the future of quantum networks looks bright. As the technology matures, we can expect to see increasingly sophisticated and secure communication networks that will revolutionize the way we connect and share information. 🚀🔮
## Conclusion 💡
Quantum networks represent a paradigm shift in the way we think about communication and cybersecurity. By harnessing the power of quantum mechanics, these networks offer the promise of virtually unhackable data transmission, increased efficiency, and a wide range of transformative applications. 💪🔐
As we continue to navigate the challenges and opportunities of the digital age, quantum networks will undoubtedly play a crucial role in shaping the future of secure and efficient communication. 🌐💡

542,053 | 利用 Excel 陣列計算不重複項目 | 因為需要計算不重複項目, 發現大家的解決方案都是在 Excel 中使用陣列公式, 所以稍微瞭解了一下陣列的用法, 果然是神兵力器, 值得學一下。 Excel... | 0 | 2020-12-14T10:47:30 | https://dev.to/codemee/excel-4d33 | excel | 因為需要計算不重複項目, 發現大家的解決方案都是在 Excel 中使用陣列公式, 所以稍微瞭解了一下陣列的用法, 果然是神兵力器, 值得學一下。
## Excel 的陣列
如果你有以下的資料, 想要算出小計：
一般的作法可能是在 B4 建立公式 `=B2*B3`, 然後再複製公式到 C4 與 D4；有了這些資料後, 我們就可以計算總價, 也就是所有小計的總和。
我們可以改用陣列公式取代上述運算, 在大多數情況下能夠節省很多操作時間。
### 使用陣列計算出選取範圍內的個別結果
以下列步驟完成同樣的結果：
1. 選取小計範圍 B4:D4:
2. 在公式欄位填入 `=B2:D2*B3:D4` 後先不要急著按下 <kbd>Enter</kbd>
5. 接著按 <kbd>Ctrl</kbd>+<kbd>Shift</kbd>+<kbd>Enter</kbd>, 你會看到小計欄位就已經填入我們所需要的結果了：
另外你也可以注意到我們剛剛填入的公式自動加上了一對大括號, 這表示這個公式是以陣列的形式運作。
陣列運作會針對範圍內的儲存格一個一個去運算, 像是剛剛的公式 `=B2:D2*B3:D4` 就是把 `B2:D2` 範圍內的儲存格與 `B3:D4` 範圍內的處存格兩兩對應相乘後放到我們選取的範圍內, 也就相當於：
```
B4 = B2 * B4
C4 = C2 * C4
D4 = D2 * D4
```
### 使用陣列匯總範圍內的資料
除了剛剛這樣用範圍內的儲存格一一計算出個別結果外, 你也可以用陣列公式匯總計算。例如要計算上述資料的總價, 我們就可以這樣做：
1. 首先在 B5 儲存格輸入公式 `=SUM(B2:D2*B3:D4)` 加上加總函數, 一樣先不要急著按 <kbd>Enter</kbd>：
2. 接著按 <kbd>Ctrl</kbd>+<kbd>Shift</kbd>+<kbd>Enter</kbd>, 你會看到總計欄位已經算出我們所需要的結果了：
同樣的, 我們輸入的公式也自動加上了一對大括號, 表示這是陣列公式。這個公式除了依照兩個範圍兩兩對應相乘外, 還會運用 SUM 公式將計算結果全部加總。
在剛剛的作法裡, 你可以看到我們其實不需要小計欄也可以直接算出總價, 而且還可以將這個公式直接套用在別的公式裡面。
## 使用陣列計算不重複項目的個數
瞭解陣列的基本用法後, 我們就可以來思考一下如何使用陣列來幫我們計算一串資料中不重複項目的個數了。假設我們有以下清單：
這裡會使用一個小技巧來計算不重複項目的個數, 我們邊做邊說明。首先計算個別項目在資料中出現的次數, 這可以透過 COUNTIF 及陣列達成：
1. 先選取 `B1:B6` 後輸入公式 `=COUNTIF(A1:A6, A1:A6)`：
2. 按下 <kbd>Ctrl</kbd>+<kbd>Shift</kbd>+<kbd>Enter</kbd>, 就會看到個別項目出現的次數出現了：
這裡 COUNTIF 要計數的範圍是 A1:A6, 而用來判斷是否計入計數的條件並不是單一儲存格, 而是一個範圍, 由於這是陣列公式, 因此這就等於是將該範圍內的儲存格一一帶入成為 COUNTIF 的判斷條件, 並將個別的計數結果一一放入我們選取的 `B1:B6` 內。也就是：
```
B1 = COUNTIF(A1:A6, A1)
B2 = COUNTIF(A1:A6, A2)
B3 = COUNTIF(A1:A6, A3)
B4 = COUNTIF(A1:A6, A4)
B5 = COUNTIF(A1:A6, A5)
B6 = COUNTIF(A1:A6, A6)
```
接著我們再計算上述出現次數的倒數, 這只在 `C1:C6` 範圍內輸入陣列公式 `=1/COUNTIF(A1:A6, A1:A6)` 就可以完成：
這裡就可以看出竅門了, C 欄是 A 欄對應資料出現次數的倒數。以橘子為例, 因為它出現 2 次, 所以在 C1 和 C6 都是 2 的倒數, 也就是 1/2。如果我們將 C 欄加總, 橘子的 2 個 1/2 相加會變成 1, 所以橘子雖然在資料中重複出現, 但加總後只會是 1。利用這個作法, 如果某個項目在資料中重複出現 N 次, 那麼加總的結果就是 N * 1/N, 也就是 1, 因此就可以計算清單中不重複項目的個數了。
有了以上的認知, 大家應該都可以猜到該怎麼算出不重複的項目的個數了, 我們在 D4 輸入陣列公式 `=SUM(1/COUNTIF(A1:A6, A1:A6))`：
就可以看到不重複項目有 4 個, 就是橘子、頻過、鳳梨、香蕉。你還可以再延伸發揮, 想看看如果清單中有空白項目時, 要怎麼處理？
請特別留意, 在 Office 365 中若輸入公式含有陣列, 也就是原本應該是單一儲存格的參數卻輸入了範圍, 會自動變成陣列公式, 但若不是 Office 365, 就一定要按 <kbd>Ctrl</kbd>+<kbd>Shift</kbd>+<kbd>Enter</kbd> 才會變成陣列公式。 | codemee |

1,904,435 | Getting started with Passwordless Authentication | Passwordless authentication is an alternative to traditional password-based authentication that is... | 0 | 2024-06-28T16:02:44 | https://dev.to/userfront/getting-started-with-passwordless-authentication-2ao4 | webdev, authentication, passwordless, learning | Passwordless authentication is an alternative to traditional password-based authentication that is gaining traction among organizations aiming to bolster their security infrastructure while enhancing user experience. This article explores the concept of passwordless authentication, its benefits for organizations, various methods, and how to implement passwordless authentication with Userfront.
## Definition of Passwordless Authentication
**Passwordless authentication** refers to the verification of a user's identity without requiring the user to enter a password. This method leverages other forms of identification like single-use codes or security keys, providing a more secure and user-friendly login experience. By eliminating the need for passwords, this authentication method mitigates common password-related security risks.
##Benefits of Passwordless Authentication for Organizations
The primary benefits of passwordless authentication boil down to three areas: security, user experience, and operational efficiency.
### Security:
- **Mitigation of Weak or Reused Password Risks:** Traditional password-based systems often suffer from weak or reused passwords, making them easy targets for cyber attackers. Passwordless Authentication eliminates this risk, offering a more secure alternative.
- **Reduced Phishing Attacks:** Phishing attempts often target password credentials. By eliminating passwords, the chances of successful phishing attacks are significantly reduced.
### User Experience:
- **Simplified Login Process:** Passwordless Authentication simplifies the login process by reducing the steps required to verify a user’s identity.
- **Elimination of Password Memorization and Resets:** Users no longer need to remember or reset passwords, which enhances the overall user experience and reduces frustration.
## Operational Efficiency:
- **Reduced Password-related Support:** Organizations often dedicate resources to handle password resets and related support issues. Passwordless authentication lowers the demand for such support.
- **Lower Operational Costs:** By reducing the need for password-related support, organizations can lower operational costs and reallocate resources to other critical areas.
## Types of Passwordless Authentication
- **Verification Codes:** Users can opt for a verification code (sometimes called a time-based one-time password or TOTP) sent to their email or SMS address. They then enter this one-time verification code instead of a password.
- **Magic Links:** Much like a verification code, except instead of a code, the user receives a link that they click on to authenticate. Magic links usually have an expiration date and can only be used once.
- **TOTP Applications:** This authentication method allows users to use a TOTP application on their smartphone to verify their identity. TOTP authentication is primarily used as a second factor in MFA signup flows because users must authenticate with the TOTP application through other factors.
- **Security Keys:** Security keys are physical devices that store cryptographic keys to authenticate users. These keys can be connected via USB, Bluetooth, NFC, or even embedded within devices.
- **Biometrics:** Biometric authentication utilizes unique biological traits such as fingerprints or facial recognition to verify a user’s identity.
- **Single Sign On:** SSO could be viewed as a form of passwordless authentication because once a user is verified with an SSO provider, they don’t need to enter an additional password to log in to additional applications.
## Implementing Passwordless Authentication with Userfront
Userfront supports the following methods of passwordless authentication:
- Magic links
- Email verification
- SMS verification
- TOTP applications
- SSO
Here is how you can enable passwordless authentication methods in minutes:
1. In your Userfront account, navigate to [your dashboard](https://userfront.com/dashboard/authentication).
2. Under “First factors,” select the methods of authentication you would like to allow. While you can choose as many methods as you’d like, we recommend just a few to keep it simple.
3. Email verification works with Userfront right out of the box. Just click the toggle, and users can log in using a code sent by Userfront.
4. Similarly, email magic links also work out of the box and do not need to be configured. If you prefer to build your own magic link experience, [follow these instructions](https://userfront.com/docs/js#login-via-link-method).
5. To set up SSO, you will need to follow the steps for each SSO provider.
6. To set up TOTP, [follow these instructions](https://userfront.com/docs/api-client#set-up-totp-authenticator).
Passwordless authentication is a solid solution for organizations aiming to enhance their security and user experience. With platforms like Userfront, implementing passwordless authentication is a straightforward process.

When it comes to government contracts, the Federal Acquisition Regulation (FAR) is the cornerstone guideline that bidders and contractors must understand. Yet, navigating FAR can often feel like deciphering a dense legal manuscript. Fear not! This blog post is here to break down some of the key sections of FAR that every contractor should know.
## What is FAR?
The Federal Acquisition Regulation (FAR) is a set of rules issued to ensure that the government acquires goods and services in a manner that is efficient, economical, and fair. It covers everything from cost principles to contract clauses, providing a comprehensive framework for federal procurement activities.
## Key Sections of FAR for Contractors
Below, we'll delve into the essential sections of FAR that are most relevant for contractors:
### **1. FAR Part 12 - Acquisition of Commercial Items**
FAR Part 12 is a game-changer for contractors and vendors dealing with commercial items. This section simplifies and streamlines the processes for acquiring commercial products and services.
**Why it matters:**
- **Streamlined Requirements:** This part allows for the use of simplified procurement procedures, making it easier and faster for businesses to enter into contracts with the government.
- **Flexible Terms:** Encourages the use of customary commercial practices, reducing the rigidity often associated with federal contracts.
### **2. FAR Part 15 - Contracting by Negotiation**
Negotiation can be the linchpin of a successful government contract deal. FAR Part 15 outlines the intricacies of this process.
**Key Takeaways:**
- **Source Selection:** Discusses how the government evaluates proposals and establishes source selection strategies.
- **Proposal Guidelines:** Guides contractors on submitting their best proposals, focusing on cost, technical capability, and past performance.
### **3. FAR Part 19 - Small Business Programs**
If you are a small business owner, FAR Part 19 holds the keys to your success in federal contracting.
**Key Features:**
- **Set-Asides:** Explains set-asides for small businesses, including the 8(a) Business Development Program, HUBZone, SDVOSB, and WOSB programs.
- **Subcontracting:** Provides rules on subcontracting plans to maximize small business participation in federal procurement activities.
### **4. FAR Part 31 - Contract Cost Principles and Procedures**
Understanding allowable and unallowable costs is crucial for financial planning and compliance. FAR Part 31 is the go-to section for this.
**Essential Elements:**
- **Cost Principles:** Defines what costs are considered allowable and allocable under government contracts.
- **Indirect Costs:** Clarifies the handling of indirect costs, which can often be a perplexing area for contractors.
### **5. FAR Part 52 - Solicitation Provisions and Contract Clauses**
This part lists the obligatory contract clauses that must be included in government contracts, which can shape your contractual obligations.
**Highlights:**
- **Standard Clauses:** Covers a wide range of clauses, including those related to changes, termination, and disputes.
- **Compliance:** Stresses the importance of including the right provisions to ensure compliance with federal requirements.
## Why Understanding FAR is Crucial
Grasping the nuances of FAR is vital for several reasons:
- **Competitive Advantage:** More adeptly navigate the bidding process, potentially increasing your odds of winning contracts.
- **Compliance:** Ensure adherence to the guidelines, minimizing the risk of legal complications.
- **Financial Prudence:** Properly manage costs and avoid penalties or sanctions related to non-compliance.
## Conclusion
The Federal Acquisition Regulation (FAR) may be dense, but understanding its key sections can offer significant advantages in the highly competitive world of government contracts.

1,904,355 | Turning Adobe Illustrator Into A People Generator (aka, A Dress Up Doll Maker) | The Problem I recently had a very tight ask: to populate an image with hundreds of unique characters... | 0 | 2024-06-28T15:56:10 | https://dev.to/kocreative/turning-adobe-illustrator-into-a-people-generator-aka-a-dress-up-doll-maker-29j1 | beginners, tutorial, codenewbie, illustrator | **The Problem**
I recently had a very tight ask: to populate an image with hundreds of unique characters in under 2 weeks. This is naturally quite a tall order, so I broke out the javascript.
I have never used javascript on anything other than After Effects, but I was aware that you could write and run scripts on other adobe programs. I cracked open the [scripting guide](https://ai-scripting.docsforadobe.dev/) and figured that what I wanted wasn't too much of an ask.
All I needed to do was draw sections of a body which were interchangeable. I have played with this idea before, making dress up dolls in my teens using flash, and more recently playing with picrew. So I needed to write a script which was smart enough to say "on each layer, turn off all sub-layers, then turn one back on randomly." Bonus points if I could also make it randomise clothes and skin colour.
Here's how I achieved this.
**Turning a random sub-layer on**
I started testing my idea out on shapes. I knew if I could make a script work for 1 layer, I could make it work for multiple. I set up a document with 1 layer and 4 sub-layers, and drew a simple shape on each: a square, a circle, a star, and a triangle.
I decided to use sub-layers instead of groups/loose path items/compound paths because it meant I could keep artwork tidy, and my code could stay consistent.
I opened up adobe ExtendScript CC. I like to use this because it can plug straight into illustrator without having to save out a .jsx file.
The first thing I needed to do was tell the script to turn all the sub-layers **off**. This is to ensure that no sub-layers are left on when the script is run multiple times. I ended up creating a function using for loops to accomplish this:
```
var doc = app.activeDocument;
function hideAll() {
for (i = 0; i < doc.layers.length; i++) {
for (a = 0; a < doc.layers[i].layers.length; a++) {
doc.layers[i].layers[a].visible = false;
}
}
};
hideAll();
```
Here, I set up a variable for my active document, to avoid typing "app.activeDocument" repeatedly throughout the script. I then created my function "hideAll". The first for loop cycles through each layer in the document in turn, then stops when it has looped through all of them (using the argument "i < doc.layers.length" to set the number of layers, and "i++" to incrementally add 1 to the i value until the maximum layer number is reached). The second loops through all the sub-layers on each layer, then stops when it has looped through all of them (referencing sub-layers in illustrator simply requires repeated use of "layers[index]", which is why I chose this workflow). As the loop goes through each sub-layer, it sets the sub-layer's visibility to "false", turning it off.
Next I needed to script turning **on** a random sub-layer. I figured all I needed was a random variable, and to set the sub-layer's visibility to true. So I created a new function:
```
function showRandom() {
for (i = 0; i < doc.layers.length; i++) {
var randomLayerCount = Math.floor(Math.random() * doc.layers[i].layers.length);
doc.layers[i].layers[randomLayerCount].visible = true;
}
};
```
showRandom goes through each layer in the document, and creates a random number for the variable "randomLayerCount" between 0 and the number of sub-layers on the current layer. It uses "Math.random" to randomise a number between 0 and 1, multiplies that number by the number of sub-layers, and then finally uses "Math.floor" to round that number down to an integer. The for loop then turns on the sub-layer whose index number corresponds to the randomly generated number. I then run both my functions together:
```
hideAll();
showRandom();
```
To randomly turn on one of the shape sub-layers.
**Randomising Colour**
It works! Now to think about colours. If the people generator is going to truly work, it needs to be able to change skin tones, hair colours, clothes colours, etc.
I ended up creating colours within the script, rather than referencing swatches, in case I wanted to repurpose the script for another document. I created my colours like this:
```
var colour01 = new CMYKColor();
colour01.cyan = 3;
colour01.magenta = 11;
colour01.yellow = 18;
colour01.black = 0;
```
Since my document needed to be for print, I used CMYK instead of RGB (if you need to use RGB, just use "new RGBColor()" instead, and set each R G B colour value). I set the values for my new colour, and did this for each colour I needed to add to my script.
I then created an array for all the colours I wanted to cycle through. In this case, I wanted to cycle through 4 different skin tone options:
```
var skinTones = [colour01, colour02, colour03, colour04];
```
And a random number which could be used to select each colour:
```
var skinRandom = Math.floor(Math.random() * skinTones.length);
```
Now to colour the shapes. I decided that I wanted to colour all the shapes at once, should I want to adjust the image after the script was run. This meant I needed to turn **on** all the sub-layers, in order to make them valid targets for the script to select. I created a new function, the opposite of hideAll:
```
function showAll() {
for (i = 0; i < doc.layers.length; i++) {
for (a = 0; a < doc.layers[i].layers.length; a++) {
doc.layers[i].layers[a].visible = true;
}
}
};
```
Now all the sub-layers were on, I could go through all the shapes in turn and change their colours with a new function:
```
function colourAll() {
for (i = 0; i < doc.pathItems.length; i++) {
doc.pathItems[i].fillColor = skinTones[skinRandom];
}
};
```
This function goes through all the pathItems in the document, and changes their colour. I decided at this point to only use pathItems in my illustrator document going forward for the final artwork. What are pathItems specifically? They are any shapes which show up as "path" when drawn in illustrator:
This meant I had to remember not to use compound paths, patterns, or anything complex when drawing parts for my people I wanted the script to recolour later (or the script would not work).
I add my new functions to the end of my script:
```
showAll();
colourAll();
hideAll();
showRandom();
```
Now the script will turn all sub-layers on, colour all the pathItems a random colour from the array, turn all the sub-layers back off, then finally select 1 at random to turn back on. This may be over complicating things, but I found that, for me, this made the most logical sense.
**Making the people generator**
From here, I had the basic building blocks I needed to make my people generator. Now I needed to think how this would work for multiple colour changes, and multiple layers. I created more shapes as a holding place for my finished artwork, across multiple layers and sub-layers.
Next I created 12 colours in total (adding to the 4 already created), to be my skin, hair and clothes colours. Then I create the arrays and random number generators, like so:
```
var skinTones = [colour01, colour02, colour03, colour04];
var skinRandom = Math.floor(Math.random() * skinTones.length);
var clothesTones = [colour05, colour06, colour07, colour08];
var clothesRandom01 = Math.floor(Math.random() * clothesTones.length);
var clothesRandom02 = Math.floor(Math.random() * clothesTones.length);
var clothesRandom03 = Math.floor(Math.random() * clothesTones.length);
var hairTones = [colour09, colour10, colour11, colour12];
var hairRandom = Math.floor(Math.random() * hairTones.length);
```
I gave clothes 3 separate random number generators, so the shirt, trousers, and shoe layers could all be different colours. Now that I had more than 1 colour array, I needed to go back and change my function "colourAll." I decided to break this into multiple functions: "colourSkin", "colourHair", "colourClothes01", "colourClothes02", and "colourClothes03." After this, I needed a way to specify which pathItem needed to be coloured with skin tones, which needed to be clothes, and which needed to be hair. I decided to do this by naming my pathItems in illustrator accordingly.
I then added an if statement to my new functions, so that they would only recolour pathItems whose names matched the function:
```
function colourSkin() {
for (i = 0; i < doc.pathItems.length; i++) {
if (doc.pathItems[i].name == "skin") doc.pathItems[i].fillColor = skinTones[skinRandom];
}
};
function colourHair() {
for (i = 0; i < doc.pathItems.length; i++) {
if (doc.pathItems[i].name == "hair") doc.pathItems[i].fillColor = hairTones[hairRandom];
}
};
function colourClothes01() {
for (i = 0; i < doc.pathItems.length; i++) {
if (doc.pathItems[i].name == "clothes01") doc.pathItems[i].fillColor = clothesTones[clothesRandom01];
}
};
function colourClothes02() {
for (i = 0; i < doc.pathItems.length; i++) {
if (doc.pathItems[i].name == "clothes02") doc.pathItems[i].fillColor = clothesTones[clothesRandom02];
}
};
function colourClothes03() {
for (i = 0; i < doc.pathItems.length; i++) {
if (doc.pathItems[i].name == "clothes03") doc.pathItems[i].fillColor = clothesTones[clothesRandom03];
}
};
```
Then updated the functions at the end of the script again:
```
showAll();
colourSkin();
colourHair();
colourClothes01();
colourClothes02();
colourClothes03();
hideAll();
showRandom();
```
I was almost there! I had a script that could change the colours in the way that I wanted. But if I wanted to have my arms, legs, and hair layers separated out (which I need to to make the artwork overlap correctly) I needed to make one small change to my showRandom function. Otherwise each arm, hair and leg layer would be randomized separately, meaning mismatching sleeve lengths and clashing artwork!
Like with the colours, I split the function into multiple functions and used my layer names in order to label everything. If a layer's artwork could be independent, and did not need the same random number as another, I named it "unit." If a layer needed to match the same random number as another, I gave it and all other layers which matched it a consistent name, such as "arm," "leg," or "hair," and made sure each had the same number of sub-layers, in the same order I wanted them to be displayed.
Then, instead of the random variable being inside the for loop for these functions, I created it **outside** of the function entirely:
```
function showUnit() {
for (i = 0; i < doc.layers.length; i++) {
var randomUnitCount = Math.floor(Math.random() * doc.layers[i].layers.length);
if (doc.layers[i].name == "unit") doc.layers[i].layers[randomUnitCount].visible = true;
}
};
var randomHairCount = Math.floor(Math.random() * doc.layers["hair"].layers.length);
function showHair() {
for (i = 0; i < doc.layers.length; i++) {
if (doc.layers[i].name == "hair") doc.layers[i].layers[randomHairCount].visible = true;
}
};
var randomLegCount = Math.floor(Math.random() * doc.layers["leg"].layers.length);
function showLeg() {
for (i = 0; i < doc.layers.length; i++) {
if (doc.layers[i].name == "leg") doc.layers[i].layers[randomLegCount].visible = true;
}
};
var randomArmCount = Math.floor(Math.random() * doc.layers["arm"].layers.length);
function showArm() {
for (i = 0; i < doc.layers.length; i++) {
if (doc.layers[i].name == "arm") doc.layers[i].layers[randomArmCount].visible = true;
}
};
```
This meant the random number wasn't re-rolled every time the for loop was used. Once again, I updated my functions at the end of the script:
```
showAll();
colourSkin();
colourHair();
colourClothes01();
colourClothes02();
colourClothes03();
hideAll();
showUnit();
showHair();
showLeg();
showArm();
```
And it was finished! The basic script for randomising body parts in illustrator.

1,904,440 | Understanding Sine Cosine and the Unit Circle Mapping Problems in a New Light | Sine and cosine functions are fundamental concepts in trigonometry that help us model periodic phenomena. By understanding these functions and their relationship to the unit circle, we can map problems in a new way and gain valuable insights into the world around us. | 0 | 2024-06-28T15:53:07 | https://www.rics-notebook.com/blog/Math/UnitCircle | trigonometry, mathematics, education, unitcircle | # 🔍 Introduction: Exploring the World of Sine and Cosine 🔍
Trigonometry is a fascinating branch of mathematics that deals with the relationships between the sides and angles of triangles. At the heart of trigonometry lie the sine and cosine functions, which are essential tools for modeling periodic phenomena and solving a wide range of problems in science, engineering, and everyday life.
In this blog post, we will dive deep into the meaning of sine and cosine waves, explore the significance of the unit circle, and discover how these concepts can help us map problems in a new and illuminating way.
# 📈 Sine and Cosine: The Building Blocks of Periodic Functions 📈
Sine and cosine are periodic functions that oscillate between -1 and 1, repeating their values at regular intervals. These functions are defined in terms of the unit circle, which is a circle with a radius of 1 centered at the origin of a coordinate plane.
## 🌊 Sine Waves: Measuring Height 🌊
The sine function, denoted as sin(θ), represents the vertical component or height of a point on the unit circle. As we move around the circle, the sine value oscillates between -1 and 1, creating a smooth, wave-like pattern.
Mathematically, the sine of an angle θ is defined as:
sin(θ) = opposite / hypotenuse
where "opposite" is the length of the side opposite to the angle θ in a right triangle, and "hypotenuse" is the length of the longest side of the triangle.
## 🌉 Cosine Waves: Measuring Width 🌉
The cosine function, denoted as cos(θ), represents the horizontal component or width of a point on the unit circle. Like the sine function, cosine values oscillate between -1 and 1 as we move around the circle.
Mathematically, the cosine of an angle θ is defined as:
cos(θ) = adjacent / hypotenuse
where "adjacent" is the length of the side adjacent to the angle θ in a right triangle, and "hypotenuse" is the length of the longest side of the triangle.
# 🎯 The Unit Circle: A Trigonometric Roadmap 🎯
The unit circle is a powerful tool that helps us visualize and understand the behavior of sine and cosine functions. By placing an angle θ in the unit circle, we can determine the corresponding sine and cosine values based on the coordinates of the point where the angle intersects the circle.
## 📐 Angles and Radians: Measuring Rotation 📐
In the unit circle, angles are typically measured in radians rather than degrees. One radian is defined as the angle subtended by an arc length equal to the radius of the circle. The circumference of the unit circle is 2π, so a full rotation around the circle corresponds to an angle of 2π radians or 360 degrees.
## 🧭 Navigating the Unit Circle: Key Angles and Coordinates 🧭
There are several key angles in the unit circle that serve as reference points for understanding sine and cosine values:
- 0 radians (0°): (1, 0)
- π/6 radians (30°): (√3/2, 1/2)
- π/4 radians (45°): (√2/2, √2/2)
- π/3 radians (60°): (1/2, √3/2)
- π/2 radians (90°): (0, 1)
- π radians (180°): (-1, 0)
- 3π/2 radians (270°): (0, -1)
- 2π radians (360°): (1, 0)
By memorizing these key angles and their corresponding coordinates, we can quickly determine the sine and cosine values for any angle in the unit circle.
# 🗺️ Mapping Problems with Sine and Cosine 🗺️
Sine and cosine functions, along with the unit circle, provide a powerful framework for mapping and solving a wide range of problems in mathematics and beyond. By understanding how these functions behave and relate to each other, we can gain new insights and approach problems from a fresh perspective.
## 🌡️ Modeling Periodic Phenomena 🌡️
One of the most important applications of sine and cosine is in modeling periodic phenomena, such as sound waves, light waves, and temperature fluctuations. By representing these phenomena as sine or cosine waves, we can analyze their properties, such as amplitude, frequency, and phase shift, and make predictions about their behavior.
For example, consider a simple pendulum swinging back and forth. The angle θ between the pendulum and the vertical axis can be modeled using a cosine function:
θ(t) = θ₀ cos(ωt + φ)
where θ₀ is the initial angle, ω is the angular frequency, t is time, and φ is the phase shift.
## 🌉 Solving Triangles and Trigonometric Equations 🌉
Sine and cosine functions are also essential tools for solving triangles and trigonometric equations. By using the unit circle and the definitions of sine and cosine, we can find missing angles and sides in triangles, as well as solve equations involving these functions.
For instance, suppose we want to find the height of a tree that casts a 20-meter shadow when the angle of elevation from the tip of the shadow to the top of the tree is 30°. We can solve this problem using the tangent function, which is defined as:
tan(θ) = opposite / adjacent
In this case, the opposite side is the height of the tree (h), and the adjacent side is the length of the shadow (20 m). Plugging in the values, we get:
tan(30°) = h / 20
Solving for h, we find that the height of the tree is approximately 11.55 meters.
# 🎉 Conclusion: Embracing the Power of Sine and Cosine 🎉
Sine and cosine functions, together with the unit circle, form the foundation of trigonometry and offer a rich set of tools for modeling periodic phenomena, solving triangles, and mapping problems in new and exciting ways. By understanding the meaning behind these functions and their relationship to the unit circle, we can unlock a world of possibilities and gain a deeper appreciation for the beauty and power of mathematics.
As you explore the fascinating world of trigonometry, remember to embrace the elegance of sine and cosine, and let the unit circle guide you on your journey. With these tools at your disposal, you'll be well-equipped to tackle a wide range of problems and discover new insights into the world around you.
So go forth, intrepid math explorer, and let the power of sine and cosine be your guide! 🧭📐🌿 | eric_dequ |

1,904,403 | Real-Time Capabilities in API Integration | As suggested by their name, real-time APIs allow applications to send and receive data in real time,... | 0 | 2024-06-28T15:51:53 | https://dev.to/apidna/real-time-capabilities-in-api-integration-45lj | api, webdev, realtime, learning | As suggested by their name, real-time APIs allow applications to send and receive data in real time, ensuring up-to-date information and immediate responses.
They are essential for applications demanding rapid response times, such as online gaming, financial trading, and IoT devices, aiming to minimise latency and ensure accurate data processing.
Unlike traditional REST APIs that rely on request-response mechanisms, real-time APIs often use WebSocket technology, providing persistent, bidirectional communication between client and server.
In this article we’ll take a look at the benefits and use cases when integrating real-time APIs.
## How Real-Time APIs Work
Real-time APIs utilise technologies such as WebSockets and Server-Sent Events (SSE) to deliver data with minimal latency.
Let’s take a look at how each of them work, and when it is appropriate to use them.
### WebSocket
WebSocket is a protocol that facilitates two-way, full-duplex communication over a single, persistent connection between the client and server.
This persistent connection allows for continuous data exchange without the overhead of establishing new connections for each request, significantly reducing latency.
Examples of appropriate WebSocket use include online gaming, live chat, collaborative tools, and financial trading platforms.
1. **Connection Establishment:** The WebSocket connection starts with an HTTP handshake. The client sends an HTTP request to the server with headers indicating the intent to establish a WebSocket connection. If the server supports WebSockets, it responds with an upgrade header, switching the protocol from HTTP to WebSocket.
2. **Persistent Connection:** Once the WebSocket connection is established, it remains open as long as both the client and server agree to keep it alive. This persistent connection enables real-time communication, allowing data to flow freely in both directions without repeated handshakes.
3. **Bidirectional Communication:** WebSocket supports full-duplex communication, meaning both the client and server can send and receive messages independently and simultaneously. This is crucial for applications requiring instant updates and interactions, such as online gaming, live chat, and collaborative tools.
4. **Event-Driven Architecture:** WebSockets operate on an event-driven model. Events, such as messages or notifications, trigger data transmission. When an event occurs on the server, it pushes the relevant data to the connected clients in real-time. Similarly, clients can send events to the server, facilitating interactive and dynamic user experiences.
### Server-Sent Events (SSE)
SSE is a protocol designed for unidirectional communication where the server sends updates to the client over a single, persistent HTTP connection.
It is particularly suitable for applications like news streaming and stock trading, where the client primarily needs to receive real-time data from the server.
1. **Connection Establishment:** SSE uses standard HTTP connections. The client initiates a connection by sending an HTTP request to the server, which responds with an HTTP header indicating the start of an SSE stream.
2. **Persistent Connection:** The server keeps the HTTP connection open and continuously sends updates to the client as new data becomes available. This persistent connection ensures that the client receives real-time updates without the need to repeatedly request new data.
3. **Unidirectional Communication:** Unlike WebSocket, SSE supports only unidirectional communication from server to client. This is ideal for scenarios where the client needs to be updated continuously, such as live news feeds, stock price updates, and social media notifications.
4. **Automatic Reconnection:** SSE includes built-in support for automatic reconnection. If the connection drops, the client automatically attempts to reconnect and resume receiving updates from where it left off, ensuring a robust and reliable data stream.
5. **Event-Driven Model:** Similar to WebSockets, SSE operates on an event-driven model. The server sends data in the form of events, each identified by an event type and containing data payloads. Clients listen for specific events and update the UI or perform actions based on the received data.
## Types of Real-Time APIs
Real-time APIs come in various forms, each tailored to specific use cases and communication patterns.
The main types include Streaming APIs, Pub/Sub APIs, Push APIs, and Event-Driven APIs.
Each type leverages different mechanisms to deliver real-time data and updates to clients efficiently, so let’s take a look at each of them.
### Streaming APIs
Streaming APIs provide continuous data streams for applications that require large volumes of real-time data.
These APIs are designed to handle persistent connections and deliver data as soon as it becomes available, ensuring minimal latency.
They are essential for applications such as live video broadcasting, real-time analytics, financial market data feeds, and IoT sensor data streams.
For instance, platforms like Twitch and YouTube Live use streaming APIs to broadcast live video content to viewers.
Streaming APIs maintain an open connection between the client and server and utilise WebSockets.
Data is pushed to the client in a continuous stream, ensuring that updates are delivered immediately as they are generated.
### Pub/Sub APIs
Pub/Sub (Publish/Subscribe) APIs utilise a messaging pattern where publishers send messages to specific topics or channels, and subscribers receive messages by subscribing to those topics.
This model supports efficient, scalable communication by decoupling message producers and consumers.
They are commonly used in distributed systems, microservices architectures, and event-driven applications.
News websites use Pub/Sub APIs to push breaking news to subscribers, while collaborative platforms like Slack use them for real-time messaging.
Publishers broadcast messages to topics without needing to know who the subscribers are.
Subscribers express interest in one or more topics and receive all messages published to those topics.
This decoupling allows for scalable and flexible communication, enabling systems to handle high message volumes and dynamic subscriber lists.
### Push APIs
Push APIs enable servers to send updates or notifications directly to clients when specific events occur.
Unlike traditional request-response models, push APIs allow the server to initiate communication, ensuring timely delivery of critical information.
They are widely used for push notifications in mobile applications and web browsers, such as social media alerts and reminders.
Push APIs rely on technologies such as Web Push Protocol for web browsers and Firebase Cloud Messaging (FCM) for mobile apps.
These allow servers to send notifications to clients even when the client application is not actively running, ensuring that users receive important updates promptly.
### Event-Driven APIs
Event-Driven APIs are based on the principles of event-driven architecture, where clients subscribe to specific events, and servers notify them when those events occur.
This model allows for real-time communication and interaction based on events within a system.
They are ideal for applications where real-time event notifications are crucial.
For instance, an IoT system might use event-driven APIs to alert users when a sensor detects a significant change.
n an event-driven architecture, components communicate by generating and responding to events.
Clients subscribe to events of interest, and servers push notifications to clients when those events occur.
This setup ensures that clients are always informed of relevant changes in real time.

1,904,437 | Understanding Indirect Cost Rates in Government Contracts | Dive into the complexities of indirect cost rates in government contracts and learn how they can impact your project’s budget and performance. | 0 | 2024-06-28T15:50:32 | https://www.govcon.me/blog/understanding_indirect_cost_rates_in_government_contracts | governmentcontracts, indirectcosts, finance | # Understanding Indirect Cost Rates in Government Contracts
Navigating the labyrinthine landscape of government contracts can be challenging, especially when it comes to understanding indirect cost rates. These rates can make or break your project's budget and performance, so it's crucial to grasp their nuances. Today, we’ll dive deep into the world of indirect cost rates, demystifying these crucial components of government contracts.
## What Are Indirect Costs?
Indirect costs are expenses that are not directly attributable to a specific project or activity. They are necessary for the general operation of an organization and for the performance of ongoing activities. Examples include:
- Administrative salaries
- Office supplies
- Utilities
- Maintenance
Indirect costs are usually divided into two categories: **overheads** and **general & administrative costs (G&A)**. While overheads are tied to the operational side of a business, G&A costs are more aligned with the administrative aspects.
## The Role of Indirect Cost Rates
Indirect cost rates are used to allocate indirect costs to specific projects, making it easier to manage and control budgets. These rates are vital in government contracts as they ensure that all projects of an organization carry their fair share of indirect costs. The rates are usually expressed as a percentage and applied to direct costs.
### Calculating Indirect Cost Rates
Calculating indirect cost rates involves several steps. Here’s a simplified overview:
1. **Identify Indirect Costs:** Gather all the indirect costs from your financial records over a given period.
2. **Determine Direct Costs:** Identify which costs can be directly attributable to specific projects.
3. **Develop Cost Pools:** Create cost pools, which are groupings of similar indirect costs.
4. **Calculate Base:** Determine the base to which the indirect costs will be applied, such as direct labor costs or direct material costs.
5. **Compute the Rate:** Divide the total indirect cost pool by the total direct cost base to get your indirect cost rate.
Consider this example for clarity:
- Total indirect costs (G&A, overheads): $500,000
- Total direct costs (labor, materials): $2,000,000
Indirect cost rate = (Total Indirect Costs / Total Direct Costs)
= ($500,000 / $2,000,000)
= 25%
This 25% rate means that for every dollar of direct costs, 25 cents should be allocated for indirect costs.
## Importance for Government Contractors
### Compliance with Regulations
Government contracts are governed by stringent regulations, such as the Federal Acquisition Regulation (FAR). Compliance with these regulations is non-negotiable and understanding indirect cost rates is essential for:
- **Proposal Preparation:** Accurate calculation ensures competitive and compliant bid proposals.
- **Audit Defense:** Proper allocation of costs can withstand government audits, which frequently scrutinize indirect costs.
### Financial Planning and Management
Accurate indirect cost rates are crucial for:
- **Budgeting:** Ensures all costs are captured, reducing the risk of underfunding.
- **Pricing Strategies:** Competitive pricing while ensuring profitability.
- **Cash Flow Management:** Predictable allocation impacts how funds are managed daily.
### Performance Measurement
Indirect cost rates offer insights into operational efficiency. High indirect costs might indicate inefficiencies in administrative processes, while lower rates could suggest a lean and well-managed operation.
## Strategies to Optimize Indirect Cost Rates
There are several strategies organizations can employ to optimize their indirect cost rates:
1. **Efficient Allocation:** Ensure accurate and fair allocation of indirect costs to cost pools.
2. **Cost Control:** Implement cost-control measures to reduce unnecessary expenses.
3. **Regular Reviews:** Conduct periodic reviews to adjust and update rates based on current financial situations.
4. **Training:** Train employees to understand costs allocation to minimize errors.
## Conclusion
Understanding indirect cost rates in government contracts is not just about compliance—it's about managing your resources efficiently. By mastering the principles behind these rates, you can enhance your financial planning, improve your project proposals, and ensure successful, compliant, and profitable operations. Dive into the numbers, optimize your costs, and watch your projects soar! | quantumcybersolution |

1,904,431 | Understanding Cost Accounting Standards CAS for Government Contracts | Dive into the world of Cost Accounting Standards (CAS) and discover how they shape government contracts, ensuring fairness, transparency, and fiscal responsibility. | 0 | 2024-06-28T15:45:13 | https://www.govcon.me/blog/understanding_cost_accounting_standards_cas_for_government_contracts | costaccounting, cas, governmentcontracts | # Understanding Cost Accounting Standards (CAS) for Government Contracts
Welcome to a deep dive into one of the most pivotal elements in government contracting: **Cost Accounting Standards (CAS)**. If you're aiming to secure a government contract, these standards are your guiding light towards fairness, transparency, and accountability. Buckle up as we explore CAS's importance, its intricate framework, and why it’s a game-changer for businesses aiming to work with Uncle Sam!
## What Are Cost Accounting Standards (CAS)?
Cost Accounting Standards (CAS) are a set of 19 stringent rules designed to achieve uniformity and consistency in the cost accounting practices of companies that engage in government contracts. Created by the Cost Accounting Standards Board (CASB), a unique entity within the U.S. Office of Federal Procurement Policy, these standards ensure that the government gets a fair deal by requiring contractors to document and follow consistent cost accounting practices.
### Why Are CAS Important?
Imagine a world without CAS – rife with inconsistent pricing, opaque bookkeeping, and mismanaged funds. CAS brings several benefits to the table:
1. **Consistency:** Ensures that companies adhere to uniform accounting principles.
2. **Transparency:** Makes cost structures clear and auditable.
3. **Fairness:** Prevents overcharging and ensures costs are allocated correctly.
4. **Accountability:** Facilitates compliance and reduces fraud risk.
For companies, embracing CAS is not just about compliance; it’s about building a reputation of transparency and reliability.
## The Framework of CAS
### Who Must Comply with CAS?
Not all contracts require CAS compliance. There are thresholds and exemptions:
- **Full CAS Coverage:** Required for contracts valued at $50 million or more in net CAS-covered awards.
- **Modified CAS Coverage:** Applies to contracts between $7.5 million and $50 million.
Exemptions include contracts awarded to small businesses, contracts for commercial items, and contracts under the simplified acquisition thresholds.
### The Nineteen Standards
Each of the 19 standards addresses a specific aspect of cost accounting. Here's a brief overview:
1. **CAS 401:** Consistency in estimating, accumulating, and reporting costs.
2. **CAS 402:** Consistency in allocating costs incurred for the same purpose.
3. **CAS 403:** Allocation of home office expenses.
4. **CAS 404:** Capitalization of tangible assets.
5. **CAS 405:** Accounting for unallowable costs.
6. **CAS 406:** Cost accounting period.
7. **CAS 407:** Use of standard costs for direct material and direct labor.
8. **CAS 408:** Accounting for costs of compensated personal absence.
9. **CAS 409:** Depreciation of tangible capital assets.
10. **CAS 410:** Allocation of business unit G&A expenses.
11. **...**
*For full detail on each standard, consult the [CAS Board website](https://www.whitehouse.gov/omb/casb).*

1,904,413 | A confusing task! | Have you ever felt a requirement was either impossible or atmost unrealistic? Like utterly confusing... | 0 | 2024-06-28T15:44:46 | https://dev.to/kramstyles/a-confusing-task-43d | backend, django, djangorest, webdev | Have you ever felt a requirement was either impossible or atmost unrealistic? Like utterly confusing and you can't wrap your head as to why such a task was given?
I'm helping a friend out on a task; he has this particularly intersting criteria he wants sorted out. Apparently he an expense tracker app he uses to store information concerning budgets, expenses made and contributions. These data are stored and obviously validation are carried out on each input to ensure amounts are floated digits, emails are emails, ... and I'm sure you know the rest.
So far everything is going well and he just received a load of information to save. The problem with this information is that more than half of the data have no phone numbers yet (yet as it could be gotten later and updated).
As we discussed on the possible solutions, I suggested leaving the phone number fields blank but he didn't want that. I suggested randomizing the phone numbers if they are blank but he didn't want that because he mentioned he would find it difficult locating them later incase he needs to update the records.
After a while, he mentioned he would love to enter the numbers himself with he pattern he would recognize. He suggested prefixing the phone number with the country code, fixed double digits and remaining 7 numbers
i.e., **(+233 (99) 1234567)**. This makes sense as he would always recognize the **99**.
Now here's the kicker, our Phone Number Serializer refused to accept this pattern and I thought it was impossible. The reason was, +233 is the Ghanian country code and **99** cannot be the first two digits after it (Ghanians should understand this).
I won't lie, I honestly told him this was impossible as to achieve this, I had to remove the **PhoneNumber **Serializer field and use a normal **CharField** and this was unacceptable professionally as other countries could be registered and we needed a validation engine avaliable.
After my brief moment of doubt, I decided to research and see how possible this was and I suprised when I found out I could actually manipulate the process to allow numbers following the pattern **+23399** and to ensure every other number entered was properly checked.
This brings me to one of the reasons I'm making this public. Apart from the fact that I'm a programmer with over 10 years of development experience trying to come into the light and make myself public, (I've hidden myself for a while. I don't know why) one other major reason is this is a task from **HNG**. I have to talk about a recent task I found difficult (in my case disturbing because I actually felt it was unrealistic).
**HNG** is a company with a mission `to empower the next generation of tech talent.` They work with the brightest technologists (programmers, designers, project managers, social media managers etc) to help them improve their skills and expand their professional network. Here's their link ([awesome link taking you to the HNG Tech official website](https://hng.tech/)).
In case you want to join their network as an intern (trust me it's awesome), you can click this **link** too ([This link, not the previous one that's bold and shouty](https://hng.tech/internship)).
They also have a love channel where they share job opportunites, you get to meet more awesome people (**like me**) and expand your professional network. Click the next link to visit ([Yes, this awesome link](https://hng.tech/premium)).
So, back to our solution. It's actually simple. I can manipulate the **Field** method of the **serializer** class and modify the expected serializer field. Like i mentioned earlier, the solution is quite simple; the **CharField** serializer field would be used for any number that is prefixed with **+23399** and any other number would have to deal with the strict validation process of the **PhoneNumberField**.
The first block of code below is the DynamicPhoneNumberField class created to handle my request.
` class DynamicPhoneNumberField(serializers.Field):
"""
Custom serializer field to handle phone numbers dynamically.
Uses CharField for Ghanaian numbers prefixed with +23399
and PhoneNumberField for others.
"""
default_error_messages = {
'invalid': 'Enter a valid phone number.',
}
def to_internal_value(self, data):
# Check if it's a prefixed Ghanaian number and use
# CharField for it.
if data.startswith("+23399") and len(data) == 13:
return serializers.CharField().to_internal_value(data)
else:
try:
# Try to parse the number using PhoneNumberField
parsed = phonenumbers_parse(data, None)
return PhoneNumberField().to_internal_value(data)
except Exception:
self.fail("invalid")`
And the code below is the serializer class where I used this life saver in the form of a codebase
`
class ContributionSerializer(serializers.ModelSerializer):
phonenumber = DynamicPhoneNumberField(required=False)
first_name = serializers.CharField(required=False)
last_name = serializers.CharField(required=False)
...
`
I smiled like a kid who found a new toy when this actually worked. I felt like a superhero (Batman to be precise) ...
If you made it this far, `Thank you for sticking around`.

Securing a government contract is an arduous yet gratifying journey, especially for small businesses. Once the ink is dry and celebratory cheers have settled, the real challenge begins: financing the contract. While the government comes with its perks—reliable payments, stability, and prestige—the road to project completion requires understanding and navigating several financing options. Buckle up as we delve into the world of contract financing, breaking down complex concepts into digestible, actionable insights.
## Types of Contract Financing
To start, it's crucial to comprehend the various types of financing available. These are the lifelines that can bridge the gap between initial project costs and the eventual government payout.
### 1. **Mobilization Financing**
Mobilization financing covers the upfront costs needed to get the project off the ground. Think of it as your startup capital for buying materials, hiring labor, and setting up logistics.
#### Features:
- Typically provided by banks or specialized lenders.
- Secured against the government contract itself.
- High-interest rates compared to other financing options.
### 2. **Progress Payments**
Progress payments are incremental payments made by the government as the project hits specific milestones. They provide a steady stream of cash flow, making it easier to manage ongoing project expenses.
#### Key Points:
- Governed by Federal Acquisition Regulation (FAR) clauses.
- Payments are made based on the percentage of work completed.
- Usually necessitate thorough record-keeping and regular audits.
### 3. **Invoice Factoring**
Invoice factoring involves selling your accounts receivable (invoices) to a factoring company at a discount. This instant influx of cash can be used to maintain liquidity without waiting for government processing times.
#### Advantages:
- Quick access to cash—often within 24-48 hours.
- Reduces the risk and hassle of collecting payments.
#### Disadvantages:
- Factoring fees can be substantial, eating into your profit margins.
- Might not be suitable for firms with low profit margins.
### 4. **Bank Lines of Credit**
A line of credit from a bank offers flexibility. It allows you to draw funds up to a pre-approved limit, repaying and borrowing again as needed without the delay of reapplication.
#### Considerations:
- Interest rates vary based on your creditworthiness and relationship with the lender.
- Generally cheaper than mobilization financing.
- Often require personal guarantees or collateral.
## Navigating Government Requirements
Understanding the nuances of government requirements is pivotal. Each financing option comes with its own set of federal regulations and compliance mandates.
### Compliance with FAR
The Federal Acquisition Regulation (FAR) is the principal set of rules in the Federal Acquisition Regulations System. Familiarize yourself with FAR clauses relating to payments, including:
- **FAR 32.5**: Governs progress payments based on cost and performance.
- **FAR 52.232-16**: Details regulations on progress payments and how they are calculated.
- **FAR 52.232-32**: Focuses on performance-based payments.
### Financial Reporting
Accurate and timely financial reporting is vital. The government demands transparency and accountability, requiring meticulous documentation of all expenditures, milestone achievements, and usage of funds. Failure to comply can result in payment delays, penalties, and even contract termination.
## Tips for Securing Government Contract Financing
### Build a Robust Financial Plan
Your financial plan should include detailed projections, including startup costs, milestone expenses, and expected cash inflows. A robust plan reassures lenders and smooths the approval process.
### Leverage Small Business Programs
Federal agencies often have programs specifically designed to assist small businesses. For instance, the Small Business Administration (SBA) offers various loan programs that can provide the necessary capital with reasonable terms.
### Maintain Strong Relationships
Cultivate relationships with financial institutions, government officials, and industry peers. Networking can open doors to more favorable financing terms and inside knowledge of new opportunities.
## Conclusion
In the labyrinth of government contract financing, knowledge is power. By understanding the various financing options and navigating the regulatory landscape adeptly, you can transform a secure government contract into a thriving business venture. Arm yourself with a solid financial plan, leverage available resources, and cultivate relationships that fortify your business's financial health. With these strategies, the journey from contract award to project completion can be as rewarding as the contract itself. | quantumcybersolution |

Explore how digit sum is used in various applications and how it could revolutionize our understanding of number theory and Exploreing. | 0 | 2024-06-28T15:37:45 | https://www.rics-notebook.com/blog/Math/DigitSum | mathematics | ## Exploring Number Theory and Digit Sum: Unveiling New Possibilities in Exploreing Large Numbers 🔢🔍
Number theory, the study of integers and their properties, has captivated mathematicians for centuries. One particularly intriguing concept within number theory is digit sum, which is the sum of the digits of a given number. While digit sum may seem like a simple notion, it has the potential to revolutionize our understanding of number theory and open up new possibilities in Exploreing large numbers. 🚀📊
## Understanding Digit Sum 🧮
The digit sum of a number is calculated by adding up all of its individual digits. For example, the digit sum of 1234 is 1 + 2 + 3 + 4 = 10. Digit sum has several interesting properties and applications in number theory, such as:
- Divisibility tests: The digit sum can be used to quickly check if a number is divisible by certain divisors, such as 3 or 9. If the digit sum of a number is divisible by 3 or 9, then the original number is also divisible by 3 or 9, respectively. 🔢✅
- Recursive digit sum: The process of calculating the digit sum can be repeated on the resulting sum until a single-digit number is obtained. This is known as the recursive digit sum or digital root. For example, the recursive digit sum of 1234 is 1, as 1 + 2 + 3 + 4 = 10, and 1 + 0 = 1. 🔄🌿
## Digit Sum and Exploreing Large Numbers 🔒🔑
Exploreing large numbers is a crucial problem in cryptography and computer science, as many encryption systems rely on the difficulty of Exploreing large composite numbers. Currently, the most efficient known algorithms for Exploreing, such as the general number field sieve, have a time complexity that grows exponentially with the size of the number being Exploreed. 💻🔐
However, exploring the relationship between digit sum and the Explores of a number could potentially lead to new insights and more efficient Exploreing methods. By calculating the digit sum of a large number and mapping it to possible Explore combinations based on the number and size of the addends, we may be able to narrow down the search space for potential Explores. 🔍➕
For example, consider the number 1234567890. Its digit sum is 45, which can be obtained by adding various combinations of numbers, such as:
- 9 + 9 + 9 + 9 + 9 = 45
- 18 + 18 + 9 = 45
- 22 + 23 = 45
By analyzing these addend combinations and their relationships to the Explores of the original number, we may uncover new patterns and insights that could help us develop more efficient Exploreing algorithms. 💡🔢
## Other Applications of Digit Sum 🌍📊
Digit sum has numerous applications beyond number theory and Exploreing, including:
1. **Checksum validation**: Digit sum is often used in checksum algorithms to verify the integrity of data transmission or storage. For example, the ISBN-10 book identification system uses a weighted digit sum to validate the correctness of ISBN codes. 📚✔️
2. **Numerology and astrology**: In numerology and astrology, digit sum is used to calculate life path numbers, destiny numbers, and other significant values that are believed to provide insights into an individual's personality and future. 🔮✨
3. **Gaming and puzzles**: Digit sum can be used to create engaging mathematical puzzles and games, challenging players to find numbers with specific digit sums or to manipulate numbers based on their digit sums. 🎮🧩
## Conclusion 🌟
As we continue to explore the fascinating world of number theory and digit sum, we may uncover new ways to approach complex problems like Exploreing large numbers. By unlocking the hidden patterns and relationships within numbers, we can expand our understanding of mathematics and develop innovative solutions to real-world challenges. 🔓💡
The potential applications of digit sum extend far beyond number theory, impacting fields such as data validation, numerology, and gaming. As we delve deeper into the properties and uses of digit sum, we may discover even more exciting possibilities and insights. 🌍💫

This way we know what we expect from our function and then write the function so that it passes the test cases. There are a total of 3 steps involved in TDD (Test-Driven Development).
1. Red - You write test cases first which fails
2. Green - You then write just enough code that passes the test cases.
3. Refactor - Now you improve the code quality
For a demonstration of TDD, we will be writing a simple function that calculates the area of a rectangle.
```
def rect(length,breadth):
return length*breadth
```
Although this function looks good the reality is that it is full of bugs let's try it out.
```
def rect(length,breadth):
return length*breadth
print(rect(5,10)) #Output: 50
print(rect(4.5,3.4)) #Output: 15.29
print(rect(3,"HELLO")) #Output: HELLOHELLOHELLO
print(rect(-3,2)) #Output: -6
print(rect(0,5)) #Output: 0
```
As we can see when we pass a string with an integer, a negative value or zero it handles them incorrectly and we get unexpected results. No side of a rectangle can have a negative value or zero nor should it accept a string value. This is where unit testing comes into place. Before writing code we first write some of the test cases.
Create a new file and make sure you add `test_` prior to the name for example, if we assume our python file's name is `app.py` then our test file should be `test_app.py`.
Write the following test cases
```
from unittest import TestCase #import TestCase class from unittest module
from app import rect #import your rect function from app.py you wrote
class testApp(TestCase): #make a class which inherits the TestCase class
'''Test rect function'''
from unittest import TestCase #import TestCase class from unittest module
from app import rect #import your rect function from app.py you wrote
class testApp(TestCase): #make a class which inherits the TestCase class
'''Test rect function'''
def test_area_of_rectangle(self):
'''Test the area of a rectangle'''
self.assertEqual(rect(5,10),50)
def test_bad_value(self):
'''Test if the function rejects invalid values'''
self.assertRaises(ValueError, rect,-5,3)
self.assertRaises(ValueError, rect,0,2)
def test_bad_types(self):
'''Test if the function rejects invalid types'''
self.assertRaises(TypeError, rect,"Hello", 3)
self.assertRaises(TypeError, rect,True, 5)
```
The first test case will check if the function is returning the expected result when passing good values.
> This is an example of 'Happy paths' in testing which tests if the function returns the expected result.
The next two test cases check if the function handles exceptions when passed bad data.
> This is an example of 'Sad paths' in testing which tests if the function's exception handlers works properly when bad data is passed.
You can either use the default test-runner that comes with Python i.e unittest.
go to the file location and type in `python -m unittest discover` this will run all the test cases. If the test case pass then it will show '.' else it will show 'E' along with the test case name with which failed. In our case if we run this we get:
So, two of the tests failed but the output was not so helpful. let's try another test runner `nosetests`
But we need few other things as well, `pinocchio` for organized output and coloured text and `coverage` for code coverage report
We need coverage to ensure that every code statement e.g if-else branches etc. are tested before pushing it to production. The code coverage should be as high as possible.
Install:
`pip install nose pinocchio coverage`
To run `nosetests` along with `pinocchio` and `coverage`
`nosetests --with-spec --spec-color --with-coverage`
The test cases highlighted in red are the ones that failed and the one highlighted in green has passed. We can also see that the code coverage for the file is 100% which is perfect. We can see that the exceptions were not raised. So let's update our code.
```
def rect(length,breadth):
if type(length) not in [int,float] or type(breadth) not in [int,float]:
raise TypeError("Length or Breadth must be int or float")
return length*breadth
```
We have added a statement to raise TypeError if the type of length or breadth is not integer or float. Let's try out our test cases.
Great! test_bad_types has passed but still, the test_bad_values is not raising an exception when it is getting a negative or zero value for length or breadth. Let's modify our code again.
```
def rect(length,breadth):
if type(length) not in [int,float] or type(breadth) not in [int,float]:
raise TypeError("Length or Breadth must be int or float")
if length<=0 or breadth<=0:
raise ValueError("Lenght or Breadth cannot be zero or negative")
return length*breadth
```
Now we have added a statement to raise ValueError when we receive negative or zero values for length or breadth. Let's try our test cases once more.
Congratulations! All the test cases have been passed, the happy paths and the sad paths have been tested, the code coverage is 100% and our `rect` function is now ready to be pushed in production.
**Quick tip:** The `nosetests` command is a long one and everytime you run it, you need to pass all the required flags to trigger pinocchio and coverage. So add a file `setup.cfg` which will contain the following:
```
[nosetests]
verbosity=2
with-spec=1
spec-color=1
with-coverage=1
cover-package=app
[coverage:report]
show_missing = True
```
I have also added `show_missing = True` parameter which will pinpoint the line numbers which are not tested. Now just run `nosetests` without any parameter or flags, it will fetch all the required configuration flags and parameters from `setup.cfg` and will provide the same result.
So we now have understood the idea of TDD. Write test cases first and let your unit test derive your code.
Thank you,
Happy Coding!

_Javascript VM in Golang_
### Introduction
Integrating user-defined scripts into backend systems can significantly enhance the flexibility and power of your applications. In this article, we will explore how to run a **JavaScript Virtual Machine** (VM) within a **Go** (Golang) application. Specifically in this example, we’ll focus on performing **HTTP body and headers transformations** via user-provided scripts.
We will be using the [**goja**](https://github.com/dop251/goja) library, a JavaScript VM written in Go, to execute JavaScript code. This setup allows developers to provide custom transformation logic for http payloads and headers.
### The Project
[Inhooks](https://github.com/didil/inhooks) is an open source project aiming to build a lightweight incoming webhooks gateway solution. As some users have requested a way to **transform http messages** before forwarding them to targets, I have been looking for a proper solution.
_Simplified Inhooks Architecture for Transforms_
### High-Level Overview
Our system listens for incoming HTTP requests, processes the payloads using a JavaScript VM, and applies user-defined transformations to the HTTP body and headers. This allows dynamic and customizable data processing, which can be very useful in various integration scenarios.
#### Features
- **Execute JavaScript in a Go application:** Run Javascript user scripts provided at runtime.
- **Transform HTTP payloads and headers** : Give users a powerful and easy-to-use method to modify incoming requests data.
- **Security and Error handling** : The VM is isolated and does not have access to the network or file system. Robust error handling ensures smooth operation and easy debugging.
#### Code Walkthrough
Let’s dive into the implementation. Below is a snippet of the core transformation function written in Go. This function takes in the original HTTP body and headers, applies the user-defined transformation script, and returns the transformed data.
```
package main
import (
"fmt"
"github.com/dop251/goja"
"net/http"
"encoding/json"
)
// transformPayload function to apply user-defined JavaScript transformations
func transformPayload(jsScript string, body []byte, headers http.Header) ([]byte, http.Header, error) {
// Create a new JavaScript VM
vm := goja.New()
// Set the HTTP body in the VM
bodyStr := string(body)
err := vm.Set("bodyStr", bodyStr)
if err != nil {
return nil, nil, fmt.Errorf("failed to set bodyStr: %w", err)
}
// Marshal headers to JSON and set in the VM
headersStr, err := json.Marshal(headers)
if err != nil {
return nil, nil, fmt.Errorf("failed to marshal headers to JSON: %w", err)
}
err = vm.Set("headersStr", string(headersStr))
if err != nil {
return nil, nil, fmt.Errorf("failed to set headersStr: %w", err)
}
// Prepare the full script with user function
fullScript := fmt.Sprintf(`
/* User Function */
%s
/* End User Function */
const headers = JSON.parse(headersStr);
var results = transform(bodyStr, headers);
[results[0], results[1]];
`, jsScript)
// Run the script
val, err := vm.RunString(fullScript)
if err != nil {
return nil, nil, fmt.Errorf("failed to execute JavaScript: %w", err)
}
// Get the results from the script
results := val.Export().([]interface{})
if len(results) != 2 {
return nil, nil, fmt.Errorf("expected 2 results in js transform, got %d", len(results))
}
// Extract and type assert the transformed payload and headers
transformedPayloadStr, ok := results[0].(string)
if !ok {
return nil, nil, fmt.Errorf("expected payload to be of type string, got %T", results[0])
}
transformedHeadersTemp, ok := results[1].(map[string]interface{})
if !ok {
return nil, nil, fmt.Errorf("expected headers to be of type map[string]interface{}, got %T", results[1])
}
// Rebuild the header object
transformedHeaders := http.Header{}
for k, values := range transformedHeadersTemp {
valuesArr, ok := values.([]interface{})
if !ok {
return nil, nil, fmt.Errorf("expected header values to be of type []string, got %T", values)
}
stringValuesArr := make([]string, len(valuesArr))
for i, value := range valuesArr {
stringValue, ok := value.(string)
if !ok {
return nil, nil, fmt.Errorf("expected header value to be of type string, got %T", value)
}
stringValuesArr[i] = stringValue
}
transformedHeaders[k] = stringValuesArr
}
// Return the final results
return []byte(transformedPayloadStr), transformedHeaders, nil
}
```
What the code above does is:
1. **Setting Up the VM:** We initialize a new JavaScript VM using _goja.New()_ and set the HTTP body and headers as variables within the VM.
2. **Running the Script:** The user-defined script is embedded within a template that parses and transforms the body and headers.
3. **Handling Results** : The transformed payload and headers are extracted, type-checked, and returned.
The users then provide a user script such as the one below in the Inhooks configuration file. This example handles a JSON body, adds a http header _X-INHOOKS-TRANSFORMED_, converts the _body.msg_ field to upper case if it is present and deletes the _body.my\_dummy\_key_ field.
```
function transform(bodyStr, headers) {
const body = JSON.parse(bodyStr);
// add a header
headers["X-INHOOKS-TRANSFORMED"] = ["1"];
// capitalize the message if present
if (body.msg) {
body.msg = body.msg.toUpperCase();
}
// delete a key from the body
delete body.my_dummy_key;
return [JSON.stringify(body), headers];
}
```
The following unit tests make sure the code is working properly:
```
package services
import (
"context"
"net/http"
"testing"
"time"
"github.com/didil/inhooks/pkg/lib"
"github.com/didil/inhooks/pkg/models"
"github.com/stretchr/testify/assert"
)
func TestMessageTransformer_Transform_Javascript(t *testing.T) {
config := &lib.TransformConfig{
JavascriptTimeout: 5000 * time.Millisecond,
}
mt := NewMessageTransformer(config)
m := &models.Message{
Payload: []byte(`{
"name": "John Doe",
"age": 30,
"locations": ["New York", "London", "Tokyo"],
"scores": [85, 90, 78, 92]
}`),
HttpHeaders: http.Header{
"Content-Type": []string{"application/json"},
"X-Request-Id": []string{"123"},
"Authorization": []string{"Bearer token123"},
},
}
transformDefinition := &models.TransformDefinition{
Type: models.TransformTypeJavascript,
Script: `
function transform(bodyStr, headers) {
const body = JSON.parse(bodyStr);
body.username = body.name;
delete body.name;
delete body.age;
body.location_count = body.locations.length;
body.average_score = body.scores.reduce((a, b) => a + b, 0) / body.scores.length;
headers["X-AUTH-TOKEN"] = [headers.Authorization[0].split(' ')[1]];
delete headers.Authorization;
return [JSON.stringify(body), headers];
}
`,
}
err := mt.Transform(context.Background(), transformDefinition, m)
assert.NoError(t, err)
assert.JSONEq(t, `{"username":"John Doe","locations":["New York","London","Tokyo"],"scores":[85,90,78,92],"average_score":86.25,"location_count":3}`, string(m.Payload))
assert.Equal(t, http.Header{"Content-Type": []string{"application/json"}, "X-AUTH-TOKEN": []string{"token123"}, "X-Request-Id": []string{"123"}}, m.HttpHeaders)
}
func TestMessageTransformer_Transform_Javascript_Error(t *testing.T) {
config := &lib.TransformConfig{
JavascriptTimeout: 5000 * time.Millisecond,
}
mt := NewMessageTransformer(config)
m := &models.Message{
Payload: []byte(`{
"name": "John Doe",
"age": 30,
"locations": ["New York", "London", "Tokyo"],
"scores": [85, 90, 78, 92]
}`),
HttpHeaders: http.Header{
"Content-Type": []string{"application/json"},
"X-Request-Id": []string{"123"},
"Authorization": []string{"Bearer token123"},
},
}
transformDefinition := &models.TransformDefinition{
Type: models.TransformTypeJavascript,
Script: `
function transform(bodyStr, headers) {
const body = JSON.parse(bodyStr);
throw new Error("random error while in the transform function");
return [JSON.stringify(body), headers];
}
`,
}
err := mt.Transform(context.Background(), transformDefinition, m)
assert.ErrorContains(t, err, "failed to transform message: failed to execute JavaScript: Error: random error while in the transform function")
}
```
### **Conclusion**
Adding a JavaScript VM to the Go project turned out to be quite easy and allows easily customizable data transformations. The **goja** library provides an efficient and straightforward way to execute JavaScript code in Go without using V8/CGO. Another option would have been to use lua scripts via [**gopher-lua**](https://github.com/yuin/gopher-lua) for example. That could be an idea for a future project.

Explore strategic steps to ensure a seamless and successful transition. | 0 | 2024-06-28T15:29:52 | https://www.govcon.me/blog/transitioning_from_subcontractor_to_prime_contractor_strategies_for_growth | businessgrowth, contracting, strategy | # Transitioning from Subcontractor to Prime Contractor: Strategies for Growth
Breaking away from the subcontractor mold and stepping up as a prime contractor can be a game-changer for your business. It's akin to manifesting your business's latent potential and scaling new heights in terms of reputation, revenue, and responsibility. Today, we delve deep into the nitty-gritty of making this significant transition effective, productive, and seamless.
## Understanding the Roles: Subcontractor vs. Prime Contractor
To ensure a successful transition, you must first understand what each role entails:
- **Subcontractor**: A subcontractor is typically hired by a prime contractor to perform a specialized task as part of the overall project. Your responsibility is to your immediate contractor, and you often operate with a narrower focus.
- **Prime Contractor**: When you're a prime contractor, you're the primary entity responsible for delivering the entire project to the client. You manage subcontractors, oversee project execution, and maintain direct communication with the client.
The leap from subcontractor to prime contractor involves more than just ascending the hierarchy—it involves escalating your skills, expanding your management capabilities, and bolstering your business operations.
## Strategy #1: Build Strong Client Relationships
The backbone of any successful prime contractor is solid client relationships. Transitioning requires trust and this trust is forged over time through:
- **Consistent Delivery**: Ensure your work as a subcontractor is exemplary. Consistency in delivering high-quality work sets the stage for larger responsibilities.
- **Open Communication**: Foster open, transparent communication channels with your clients. Keep them informed about project progress, challenges, and milestones.
- **Client Feedback**: Actively seek feedback and make improvements. Demonstrating that you value client input builds confidence in your ability to handle larger projects.
## Strategy #2: Expand Your Skill Set and Resources
As you transition, you’ll need to broaden your expertise and resources:
- **Project Management**: Gain proficiency in project management methodologies like Agile and SCRUM. These frameworks will help you manage multiple moving parts more effectively.
- **Technical Skills**: Diversify your technical portfolio. Being knowledgeable about a wide range of related fields (e.g., integrating software development with cloud computing) showcases your capability to handle comprehensive projects.
- **Human Resources**: Expanding your team is crucial. Hiring skilled professionals who bring diverse expertise can help you handle larger, more complex projects.
## Strategy #3: Develop a Robust Bid Proposal System
Winning prime contracts typically involves a competitive bidding process. A carefully crafted bid proposal can set you apart:
- **Understand the Client's Needs**: Tailor your proposals to clearly outline how your approach aligns with the client's specific needs and pain points.
- **Evidence of Success**: Include case studies and past successes as a subcontractor. Demonstrate metrics and tangible outcomes you've achieved.
- **Cost-Benefit Analysis**: Present a clear cost-benefit analysis. Showing clients the tangible value they get for their investment can make your proposal more compelling.
## Strategy #4: Foster Strategic Partnerships
Building alliances with other subcontractors and firms can multiply your strength:
- **Collaborate**: Form joint ventures where skills complement each other. Such partnerships can tackle larger projects more effectively.
- **Mentor Networks**: Join networks or groups of seasoned prime contractors who can provide mentorship and strategic advice.
## Strategy #5: Invest in Marketing and Branding
Lastly, elevate your market presence and brand credibility:
- **Online Presence**: Invest in a professional website, robust SEO practices, and active social media profiles. Showcasing your work and expertise online can attract larger clients.
- **Content Marketing**: Publish case studies, whitepapers, and blogs. Demonstrating thought leadership can position you as a prime choice for large projects.
- **Industry Participation**: Attend industry conferences, trade shows, and seminars. Networking in these spaces can provide invaluable opportunities for growth and visibility.
## Final Thoughts
Transitioning from a subcontractor to a prime contractor is not just a shift in title—it's a strategic advancement in your business’s evolution. It requires careful planning, diligent execution, and relentless pursuit of excellence. But with the right strategies in place, the rewards—both tangible and intangible—are enormous.
Seize the opportunity, elevate your game, and watch your business soar to new heights!

1,904,338 | APNs (Apple Push Notification service) using Laravel | In this post, I will discuss the only Laravel end functionality, assuming you have 'certificate.p12',... | 0 | 2024-06-28T15:28:40 | https://dev.to/asadut_zaman/apns-apple-push-notification-service-using-laravel-3odc | In this post, I will discuss the only Laravel end functionality, assuming you have 'certificate.p12', 'password', and 'app_bundel_id' from Apple
**Step 1**
If you have 'Certificates.p12' you need to convert this to 'Certificates.pem' file. I have stored my 'Certificates.p12' file in the 'storage' directory.
In .env
```
APN_ENVIRONMENT=sandbox
APN_CERTIFICATE_PATH=storage/Certificates.p12
APN_CERTIFICATE_PASSWORD=123456
APN_APP_BUNDLE_ID=com.btrac.ems
```
Now run the below comment to your project terminal
`openssl pkcs12 -in storage/Certificates.p12 -out storage/Certificates.pem -nodes -clcerts`
that command convert my 'Certificates.p12' file into 'Certificates.pem' file
**Step 2**
Create app/helper.php
```
<?php
if (! function_exists('createApnPayload')) {
function createApnPayload($title, $body) {
return json_encode([
'aps' => [
'alert' => [
'title' => $title,
'body' => $body,
],
'sound' => 'default',
],
]);
}
}
if (! function_exists('sendApnNotification')) {
function sendApnNotification($deviceToken, $payload) {
$certificatePath = storage_path('Certificates.pem');
$passphrase = env('APN_CERTIFICATE_PASSWORD', ''); // Use the passphrase if set, otherwise empty
$url = "https://api.sandbox.push.apple.com/3/device/$deviceToken"; // Use 'api.push.apple.com' for production
$headers = [
'apns-topic: ' . env('APN_APP_BUNDLE_ID'),
'Content-Type: application/json',
];
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_PORT, 443);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $payload);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSLCERT, $certificatePath);
curl_setopt($ch, CURLOPT_SSLCERTPASSWD, $passphrase);
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_2_0);
$response = curl_exec($ch);
if (curl_errno($ch)) {
throw new Exception('cURL error: ' . curl_error($ch));
}
$httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
if ($httpCode == 200) {
return 'Notification sent successfully';
} else {
return 'Notification failed with HTTP code ' . $httpCode . ' and response ' . $response;
}
}
}
```
**Step 3**
Create a Controller for example 'NotificationController.php'
```
public function sendNotification()
{
$deviceToken = 'Your_device_token';
$title = 'Hello';
$body = 'Hello from the other side';
$payload = createApnPayload($title, $body);
try {
$result = sendApnNotification($deviceToken, $payload);
return response()->json(['message' => $result]);
} catch (\Exception $e) {
return response()->json(['error' => 'Notification failed: ' . $e->getMessage()], 500);
}
}
```
**Step 4**
Make a new route for your notification function in web.php
`Route::get('/sendNotification3', [NotificationController::class, 'sendNotification']);`
Now you can test the notification functionality form Postman or browser or call the function from any other function depending on your business logic.
**Save device token**
```
public function userDeviceToken(Request $request, $profileId)
{
$token = $request->device_token;
$user = User::find($profileId);
if ($user) {
$user->device_token = $token;
$user->save();
$response = [
'code' => 200,
'message' => 'Device token updated successfully',
'device_token' => $token
];
return response()->json([
'results' => $response
], 200);
} else {
return response()->json([
'results' => [
'code' => 404,
'message' => 'User not found'
]
], 404);
}
}
```

1,904,411 | Solving User Authorization Issues for Deposits in a Fintech Project | The fintech world is constantly changing and securing financial transactions is of utmost importance.... | 0 | 2024-06-28T15:27:24 | https://dev.to/ubong_patrick/solving-user-authorization-issues-for-deposits-in-a-fintech-project-566l | The fintech world is constantly changing and securing financial transactions is of utmost importance. Recently, I faced a particularly challenging problem in a fintech project I was working on. The task was to ensure that only authorized users could make deposits into their accounts. Despite using JSON Web Tokens (JWT) for authentication and authorization, I ran into some significant roadblocks. Here's a personal account of how I tackled this issue and finally found a solution.
Imagine this: You’ve done a decent job building a fintech application using Node.js, Express, MongoDB, and JWT. You’re feeling pretty good about it, but then you realize that your user authorization isn't working as expected. Valid tokens aren’t being recognized, and worse, invalid tokens are slipping through the cracks. This isn’t just a bug; it’s a security nightmare waiting to happen. Frustration sets in as you try to figure out what went wrong.
**These Are The Steps I Followed To Resolve The Issue**
**Step 1: Identifying the Root Cause**
First, I needed to relax my mind and carefully identify why the JWT authorization was failing. This meant digging deep into the potential issues and these where the questions I asked myself:
- Was the token generation process flawed?
- Were tokens being stored and retrieved correctly?
- Was the middleware for token verification functioning as intended?
- Were the authorization checks in the deposit route properly configured?
**Step 2: Correcting JWT Generation**
Making sure to use a strong secret key and including necessary user information in the token payload was the first step toward regaining control.
**Step 3: Storing and Retrieving Tokens**
Next, I ensured that tokens were correctly sent to the client and stored securely. Tokens should typically be stored in HTTP-only cookies or local storage on the client side. Here's an example of how to set an HTTP-only cookie in Express:
**Step 4: Implementing Token Verification Middleware**
The next step was to verify tokens for protected routes. I implemented middleware to check if the token provided in the request header was valid. Here's how I did it:
**Step 5: Implementing Authorization in the Deposit Route**
With the token verification in place, I added the authorization check in the deposit route. This ensured that only authenticated users could make deposits. Here’s the implementation:
**Step 6: Testing the Implementation**
Finally, after implementing these steps, I tested the authorization flow rigorously:
- Verified that valid tokens allowed access to the deposit route.
- Ensured that invalid or expired tokens were correctly rejected.
- Checked that unauthorized users couldn't make deposits.
When I saw everything working perfectly, it was a moment of great relief. The frustration and uncertainty I felt earlier were replaced with satisfaction and fulfilment. It was a reminder that persistence pays off and that every problem, no matter how daunting, has a solution if approached methodically.

With the shared metadata... | 0 | 2024-06-28T15:27:06 | https://dev.to/ayush9892/how-to-query-spark-tables-from-serverless-sql-pools-in-azure-synapse-8e8 | azure, serverless, sql | ## Introduction
Say goodbye to constantly running Spark clusters! With the shared metadata functionality, you can shut down your Spark pools while still be able to query your Spark external tables using Serverless SQL Pool. In this blog we dive into, how Serverless SQL Pool streamlines your data workflow by automatically synchronizing metadata from your Spark pools.
---
## Shared Metadata functionality
Azure Synapse Analytics allows the different workspace computational engines to share databases and tables between its Apache Spark pools and serverless SQL pool.
When we create tables in Apache Spark Pool, whether managed or external, the Serverless SQL pool automatically synchronizes its metadata. This metadata synchronization automatically creates a corresponding external table in a serverless SQL pool database. Then after a short delay, we can see the table in our Serverless SQL pool.
<u>Create a managed table in Spark and query from serverless SQL pool</u>
Now we can shut down our Spark pools and still be able to query Spark external tables from serverless SQL pool.
>
**Note**: Azure Synapse currently only shares managed and external Spark tables that store their data in Parquet, DELTA, or CSV format with the SQL engines. Tables backed by other formats are not automatically synced. You may be able to sync such tables explicitly yourself as an external table in your own SQL database if the SQL engine supports the table's underlying format. Also, External tables created in Spark are not available in dedicated SQL pool databases.
---
## Why we get an error if you use `dbo` schema in Spark pool or if you don’t use `dbo` schema in Serverless SQL pool?
The `dbo` schema (short for “database owner”) is the default schema in SQL Server and Azure Synapse SQL pools.
Spark pool only supports user-defined schemas. Means, it does not recognize `dbo` as a valid schema name. While in serverless SQL pool, all the tables belong to the `dbo` schema, regardless of their original schema in Spark pool or other sources. | ayush9892 |

In the vast realm of mathematics, there exists a surprising and counterintuitive principle known as Benford's Law. This statistical phenomenon has far-reaching applications, from exposing financial fraud to ensuring the integrity of AI-generated content. But what if we could harness the power of Benford's Law and digitums to gain new insights into not just the digital world, but also the natural world around us? 🌍💡
### Understanding Benford's Law 📊
Benford's Law, also known as the First-Digit Law, states that in many naturally occurring collections of numbers, the leading digit follows a specific distribution pattern. According to this law, the probability of each leading digit can be calculated using the following formula:
$$
P(d) = \log_{10}(1 + \frac{1}{d})
$$
where $d$ is the leading digit (1, 2, ..., 9). This means that the number 1 appears as the first digit about 30.1% of the time, while the number 9 appears only 4.6% of the time.
Here's a table showing the expected frequencies of each leading digit according to Benford's Law:
| Leading Digit | Probability |
| ------------- | ----------- |
| 1 | 30.1% |
| 2 | 17.6% |
| 3 | 12.5% |
| 4 | 9.7% |
| 5 | 7.9% |
| 6 | 6.7% |
| 7 | 5.8% |
| 8 | 5.1% |
| 9 | 4.6% |
To illustrate this concept, let's consider a real-world example:
🏦 Imagine you're an auditor reviewing a company's financial statements. You notice that the distribution of the leading digits in the transaction amounts deviates significantly from Benford's Law. This could be a red flag indicating potential fraud or manipulation.
### Benford's Law in Action 🕵️♂️
Benford's Law has proven to be a valuable tool in various domains, including:
- **Fraud Detection**: Auditors use Benford's Law to identify potential fraud or manipulation in financial data. Deviations from the expected distribution can indicate tampering.
- **Ensuring Data Integrity**: In the era of big data and AI, Benford's Law helps verify the authenticity of large datasets.

1,904,368 | Why DeFi Protocols Should Migrate from Push Oracles to Pull Oracles: A Case for the Pyth Network | Introduction In the dynamic world of decentralized finance (DeFi), oracles play a crucial... | 0 | 2024-06-28T15:14:43 | https://dev.to/skandesh_304185c05025ba6c/why-defi-protocols-should-migrate-from-push-oracles-to-pull-oracles-a-case-for-the-pyth-network-522l | oracle, defi, blockchain, web3 | ##Introduction
In the dynamic world of decentralized finance (DeFi), oracles play a crucial role in bridging the gap between blockchain systems and real-world data. With the rapid evolution of DeFi, the need for accurate, timely, and reliable data has never been more critical. Traditionally, push oracles have been the go-to solution, but the emergence of pull oracles, exemplified by the Pyth Network, presents a compelling case for a paradigm shift. This article explores why DeFi protocols should consider migrating from push oracles to pull oracles, supported by quantitative evidence and real-world examples.
##Understanding Oracles in DeFi
Oracles are essential components in the DeFi ecosystem, enabling smart contracts to interact with and process external data. They ensure that blockchain applications can access off-chain information such as asset prices, weather conditions, and sports scores, thereby expanding the functionality and applicability of decentralized applications (dApps). Accurate data is paramount, as inaccuracies can lead to financial losses, security vulnerabilities, and diminished user trust.
##Push Oracles: An Overiew
Push oracles operate by periodically updating on-chain prices based on predefined conditions. These updates are executed by a set of permissioned operators who commit to a specific update frequency or price movement threshold. Examples of push oracle providers include Chainlink and Band Protocol. While push oracles offer advantages such as automated updates and established market presence, they also have notable limitations. These include potential inefficiencies due to unnecessary updates, higher costs, and the risk of data manipulation by malicious operators.
##Pull Oracles: A New Paradigm
Pull oracles, in contrast, update on-chain prices only when requested. This model introduces greater flexibility and efficiency, as updates are triggered by user demand rather than a fixed schedule. The Pyth Network exemplifies this approach, allowing anyone to permissionlessly update the on-chain price by requesting the latest data from an off-chain service. This method reduces unnecessary updates, lowers costs, and enhances data accuracy.
##Case Study: _Pyth Network_
The Pyth Network stands out as a leading pull oracle provider, delivering real-time asset price data with high fidelity. Launched in April 2021, Pyth has rapidly grown to offer over 500 low-latency price feeds across various asset classes, including digital assets, FX, ETFs, equities, and commodities. The network comprises major exchanges, market makers, and financial services providers, ensuring a robust and reliable data stream. Quantitative analysis reveals that Pyth's pull oracle design significantly reduces costs and improves data accuracy compared to traditional push oracles.
##Why DeFi Protocols should migrate to Pull Oracles
1. **Improved Data Accuracy and Reliability:** Pull oracles provide data on demand, ensuring that information is up-to-ate and relevant when needed. This reduces the likelihood of using outdated or incorrect data in smart contracts.
2. **Enhanced Security and Fraud Prevention:** By decentralizing the data update process and allowing anyone to request updates, pull oracles mitigate the risk of data manipulation and centralization vulnerabilities.
3. **Cost Efficiency and Resource Optimization:** Pull oracles eliminate unnecessary updates, reducing transaction fees and resource consumption. This makes them a more economical choice for DeFi protocols.
4. **Flexibility and Scalability:** The on-demand nature of pull oracles allows them to scale more efficiently with the growth of DeFi applications, adapting to varying data requirements without overburdening the network.
##Quantitative Evidence and Analysis
Data from the Pyth Network demonstrates a marked improvement in cost efficiency and data accuracy. For instance, Pyth's model shows a reduction in unnecessary updates by up to 50%, leading to significant savings in transaction fees. Additionally, the real-time data provided by Pyth ensures more accurate pricing, which is crucial for high-frequency trading and other time-sensitive applications.
##Challenges and Considerations
Despite the advantages, migrating from push to pull oracles presents certain challenges. These include technical complexities in integrating pull oracles into existing systems, potential delays in data retrieval, and the need for robust verification mechanisms to ensure data authenticity. DeFi protocols must carefully evaluate these factors and implement strategies to address them, such as hybrid models combining the strengths of both oracle types.
#An example to understand this much better -
This will involve fetching the latest price from Pyth's off-chain service and then submitting this price to an on-chain smart contract.
```
import requests
from web3 import Web3
PYTH_API_URL = "https://pyth.network/api/latest_price"
INFURA_URL = "https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID"

'gasPrice': web3.toWei('50', 'gwei')
})
signed_txn = web3.eth.account.sign_transaction(transaction, private_key=PRIVATE_KEY)
tx_hash = web3.eth.send_raw_transaction(signed_txn.rawTransaction)
tx_receipt = web3.eth.wait_for_transaction_receipt(tx_hash)
print(f"Submitted price for {asset}: {price}. Transaction hash: {tx_hash.hex()}")
return tx_receipt
except Exception as e:
print(f"An error occurred while submitting price for {asset}: {e}")
return None
def main():
# Connect to Ethereum node
web3 = Web3(Web3.HTTPProvider(INFURA_URL))
if not web3.isConnected():
print("Failed to connect to Ethereum node. Exiting.")
return
# Instantiate smart contract

return
# Submit prices to the smart contract
for asset, price in prices.items():
submit_price_to_contract(web3, contract, asset, price)
if __name__ == "__main__":
main()
```
1. `fetch_price(asset)`: Fetches the latest price of a single asset from Pyth Network's API.
2. `submit_price_to_contract(web3, contract, asset,price)`: Submits the fetched price to the smart contract on Ethereum.

1,904,384 | Is pixel-perfect front-end development still a thing? | Pixel-perfect front-end often sparks heated debates among developers. How come? While some view it as... | 0 | 2024-06-28T15:11:47 | https://dev.to/momciloo/is-pixel-perfect-front-end-development-still-a-thing-1ban | Pixel-perfect front-end often sparks heated debates among developers. How come? While some view it as a relic of the past, others view it as a crucial quality standard. Clearly, pixel-perfect has become a more popular goal with the advent of new tools and libraries.
However, the question remains: Does pixel-perfect still matter?
## Pixel-perfect front-end: Back in the days vs Now
Pixel perfection was challenging to achieve before frontend frameworks like Bootstrap and design tools like Figma became popular. Using programs such as Photoshop, developers had to measure every pixel precisely to ensure it matched the design requirements. It was not only preferred but also necessary to guarantee that the finished product fulfilled the client's expectations and to pay close attention to every last detail.
With the appearance of responsive design and a boom of devices with different screen sizes, the focus has shifted. The web is no longer a static canvas, and achieving flawless design across all devices is even more difficult.
Flexbox, CSS Grid, and other current layout methods enable developers to build fluid, responsive designs that effortlessly adjust to various screen sizes. Precision is still necessary, but the emphasis has shifted to consistency.
### The challenge of consistency
Despite the shift in focus, the issue of creating a consistent design persists. Designers and developers must collaborate closely to ensure that the final result is consistent with the design goal. Miscommunication and varying expectations can result in disagreements that frustrate both parties.
A well-defined design system reduces the random usage of space and other design components, making it easier to obtain pixel-perfect results. A design system promotes uniformity and precision, which is necessary to maintain the application's visuality and functionality. So, if you want to achieve that, the code is literally identical to the design. Don't throw away a pixel-perfect design concept so easily.
# **3 reasons why pixel-perfect matters**
Perfect design means that you have a good design, professionally done in tools like Figma, and then you code it so that it is identical to the design. This attention to detail is essential for several reasons:
**Client expectations**: There are a million free templates available today, and they're all very nicely designed and mostly pixel-perfect. Platforms such as Webflow, Squarespace, and Wix have elevated clients' standards and expectations. They expect their site to be pixel-perfect and to match the design closely, with no big variations.
**Besides consistency, spacing and alignment count too**:
A design system is a precisely designed collection of components, such as buttons, inputs, dropdowns, date pickers, photo galleries, etc. For example, IBM's Carbon design system includes over 50 components that share common typography sizes, spacing, rounding, and more. If the frontend implementation is superficial, the whole application will look amateurish, leading to major UX problems. Small variations in any component can add up to cause serious alignment problems.
**Professional Appearance**: To a keen designer's eye, non-pixel-perfect sites look amateurish. Even to a non-sharp eye, the overall experience on such a site is not as impressive and pleasant as when the site or web application is pixel-perfect. Precision in design translates to a more professional and appealing user experience.
## How to create pixel-perfect website
Getting exact code as a design is challenging and not so simple, but yet achievable. Here are some tips that any fronted engineer should know and practice:
### Design files
The first step is to ensure that your design files are correctly prepared. Whether you use Figma or Figma alternatives, export your resolution assets at 1x resolution. This approach simplifies the whole process and makes future changes easier.
### CSS best practices
Using a CSS framework like Tailwind CSS for common UI elements can be helpful. Use a CSS reset or normalizer to eliminate browser inconsistencies, particularly with positioning components, and as a result, you will get defined font sizes, margins, and other properties and therefore consistency.
### Image handling
When photos are used in the design, using the maximum width dimension is always better to avoid distortion. Also, don't hesitate to cache element dimensions in CSS variables.
### Stop optimizing for every screen size
Avoid over-optimization for screen sizes, instead create fluid design and optimize for standard breakpoints.
Values of common CSS breakpoints are:
- **320px or 480px (for mobile phones)**
- **768px (for tablets)**
- **1920px (for desktop computers)**
These breakpoints are the spots where the website will automatically transform for viewing on a specific screen size.
### Don't forget about colors and spaces
Consistency in spacing and colors is crucial for a professional look. Assemble components on template pages and review design specs such as padding, margins, and heights for each new page or section.
### Use Version Control
Implementing version control in your design process ensures that changes can be tracked, reviewed, and reverted if necessary. This is particularly useful when collaborating with other designers and developers, as it helps maintain the integrity of the design over time.
### Design reviews
Conduct regular design reviews between designers and developers. Both design and developers follow the component-based design, which means concentrating on compositing a set of standard components. Ensure that designers and frontend engineers stick to the predefined colors, typography, and grid.
## Still thinking of ditching pixel-perfect? Think twice.
In an era where user experience must be outstanding, pixel perfection is not just an aesthetic preference but a necessity.
While the web is no longer a static canvas and the focus has shifted towards responsive design, today, more than ever, websites need to be pixel-perfect. This attention to detail sets professional developers apart and ensures that the final product meets both the client's and the designer's expectations.
By leveraging modern tools, frameworks, and design systems, developers can navigate the complexities of responsive design while still maintaining the precision that pixel-perfect development demands. | momciloo |
