Hi, lovely subscribers! 

Welcome to the first edition of Behind The Helm, your monthly dose of K8s news. Today, we’ve got a mix of info about KubeCon EU, interesting new tooling, and some fascinating blog posts for your perusal.

Earlier this month, there were some great community events in Europe. Two Scalers went to KCD Amsterdam and met some awesome people, and if the FOMO isn’t too strong you can [read about their experience](https://www.scaleway.com/en/blog/kcd-ams-2023/). KCD Paris was also a roaring success; the organisers spent nine months of volunteer work making it happen, and Scaleway was proud to be a sponsor!

KubeCon EU is coming up! Find out what you need to know about spending time in Amsterdam in this [great blog post](https://loft.sh/blog/surviving-amsterdam-during-kubecon-eu-2023/) from Lian Li. Co-located events at KubeCon are also filling up fast, so make sure to register for anything that’s a must-attend for you. Check out [the schedule](https://events.linuxfoundation.org/kubecon-cloudnativecon-europe/program/schedule/) and see what’s good!

[KWOK was announced](https://kubernetes.io/blog/2023/03/01/introducing-kwok/) at the beginning of this month and it looks very exciting; it’s a tool for mocking pods and nodes, allowing you to simulate enormous clusters with minimal resource usage. If you’re developing new K8s tooling or stress testing a configuration, it could be worth a look!

The deprecated image registry at `k8s.gcr.io` will [no longer be updated after April 3rd](https://kubernetes.io/blog/2023/02/06/k8s-gcr-io-freeze-announcement/), meaning that if you haven’t switched over to the new one at `registry.k8s.io` you’ll be missing out on updates including security patches. Get your manifests and Helm charts updated!

David Flanagan of [Rawkode Academy](https://rawkode.academy) is launching a new podcast: Cloud Native Chronicles. It’ll focus on the cloud native landscape, and the [first episode](https://community.rawkode.academy/c/cloud-native-compass/cloud-containers-kubernetes) features our very own Eli Holderness ([that’s me!](https://twitter.com/EliHolderness)).

Finally, Scaleway has some great new blog posts out this month covering K8s topics. Learn about l[oad balancing for your cluster](https://www.scaleway.com/en/blog/kubernetes-load-balancer/), or take a journey into the world of [documentation translation and managing open-source communities](https://www.scaleway.com/en/blog/on-kubernetes-human-languages-and-building-open-source-communities/).

That’s all for this month! May your clusters be fully operational, and your deployments smooth.

Yours,
Eli & the rest of the Scaleway team

C++ for algorithms (part 1.)
Tags: stl, algorithms, cpp, atcoder
Published: 2023-05-05 11:41:20

## Introduction

I haven't been using C++ for a while, so I'm writing some notes while I solve some algorithm challenges.

## Tip #0: Create a vector

```c++
vector<int> v; // empty vector

vector<int> v(n); // vector of size n - can be dynamic

vector<int> v(n, 42) // initialize all n-elements to 42

vector<int> v{0, 1, 2, 42}; // 4 elements like in the list
```

## Tip #1: Find the biggest (smallest) element in vector

```c++
#include <algorithm>

//....
auto biggest = *max_element(v.start(), v.end());
auto smallest = *min_element(v.start(), v.end());
```

## Tip #2: foreach loop

```c++
long sum = 0;
for (auto &d : v)
  sum += d;
```

## Tip #3: convert integer to string

Old C-style

```c++
#include <cstdlib>
//....
char buf[10];
int n = 123;
sprintf(buf, "%d", n);
```

C++ style

```c++
string s = to_string(34);
```

# Tip #4: find element in vector

```c++
#include <algorithm>

int value = 42;
auto iterator = find(v.begin(), v.end(), value);
// if not found, iterator == v.end()
auto index = iterator - v.begin();
```

# Tip #5: make a struct sortable

```c++
struct Edge {
  int start;
  int end;
  int cost;

  bool operator<(const Edge &other) const { 
    return this->cost < other.cost; 
  }
};
```

## Easy problems to practice

How to run driver tests for Apache Age
Tags: apacheage
Published: 2023-05-03 15:22:58

When you make some changes to Apache AGE code, it's important to check if those changes are causing errors. You can do this using AGE's `installcheck` command, which runs regression tests. 

However, AGE also has four drivers (Go, NodeJS, Python, and JDBC) with their individual tests, and testing them can be a tedious process. You need to go to each driver's folder, find the `README.md` file, follow the instructions, download dependencies, and run the appropriate commands.

Fortunately, there's an easier way to test these drivers using Github Workflows. 

Follow these steps:

- Fork the Apache Age repository to your Github account.
- Make any changes you want and push them to a separate branch of your fork.
- Change the '.yml' files in `.github/workflows` folder. Each file has the following code:
 ```
 on:
 push:
 branches: ["master", "PG11"]
 pull_request:
 branches: ["master", "PG11"]
 ```
  Remove `"PG11"` from these lines.
- Submit a pull request to the master branch of your fork.
- You can now run all the tests by going to the Checks tab on your Github account.
- After verifying that all the results are accurate, remove the commits you made in the `.github/workflows` folder. Alternatively, delete the pull request and branch, create a new branch and push the changes but do not modify the `.github/workflows` files this time.

By following these steps, you can easily test the AGE drivers and ensure that your changes don't cause any errors. This method saves you time and effort compared to manually testing each driver.

The Emergence of Self-Governing NFTs in the Art World
Published: 2023-05-05 11:08:04

Collectors now have the opportunity to own a one-of-a-kind piece of art and have a say in how it is displayed and distributed, thanks to the emergence of self-governing NFTs. This forward-thinking development was made possible by NFT marketplace development services constantly pushing the limits of what is possible.

**What Are Self-governing NFTs?**
Self-governing NFTs allow for decentralized ownership and decision-making. Unlike traditional art ownership, which gives the collector little control over how the artwork is displayed or sold, self-governing NFTs give collectors a voice. They can vote on how the art is displayed, who can view it, and even who can purchase it.

**Energizing Art Collections for the Future with NFT Marketplace Development Services**
[NFT marketplace development](https://www.pyramidions.com/nft-marketplace-development) is at the forefront of this new era in the art collection. They are the ones who are working on the technology that will allow self-governing NFTs to exist. These services constantly innovate and improve their offerings to provide collectors with the best possible experience. Thanks to NFT marketplace development services, art collectors can now access a new world of possibilities.

NFT marketplaces constantly push the boundaries of what is possible and are the driving force behind this innovation. Thinking about how art collections will evolve as technology advances is exciting!

Mastering Debounce and Throttle: Improve Your Web Performance with Ease
Tags: javascript, webdev, programming, react
Published: 2023-05-05 10:27:13

Get the most out of your web applications by learning when and how to use debounce and throttle functions

Introduction:

When building web applications, developers often face a common challenge:

optimizing the performance of their apps, especially when it comes to handling user interactions. Debouncing and throttling are two powerful techniques used to improve performance by controlling the rate at which events are triggered. In this blog post, we will explore both concepts and provide practical examples to help you understand when and how to implement them in your projects.

1) Understanding Debounce and Throttle

Debouncing and throttling are used to limit the number of times a function is called within a specified time frame, reducing the impact of repetitive and rapid user interactions on your application’s performance. Here’s a brief overview of each technique:

- Debounce: Delays the execution of a function until a specified amount of time has passed since the last time the function was called. If the function is called again before the time has elapsed, the timer is reset, and the process begins again.

- Throttle: Ensures that a function is only executed once during a specified time period, regardless of how many times it is called.

2) Real-World Use Cases
Debouncing and throttling are commonly used in the following scenarios:

Search input: Debounce can improve the search experience by only triggering the search request when the user has stopped typing, reducing unnecessary requests to the server.

Scroll events: Throttle is useful for handling scroll events, ensuring that the function is not executed too frequently, and improving the performance of features such as infinite scrolling or lazy loading.

3) Implementing Debounce and Throttle

Here’s how you can create simple debounce and throttle functions in JavaScript:


![JavaScript](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/2obupyg3futl8l0fm1ui.png)

4) Practical Examples

Let’s see how to implement debounce and throttle in real-world scenarios:

A. Debounce — Search Input

B. Throttle — Scroll Event

Conclusion:

Debouncing and throttling are essential techniques for optimizing the performance of web applications that handle user interactions. By understanding their differences and how to implement them, you can significantly improve the responsiveness and user experience of your projects. Next time you face performance issues due to repetitive events, consider using debounce or throttle to streamline your app’s behavior!

Tailwind CSS and HTML for Production without Framework
Published: 2023-05-05 10:07:12

Want to use plain old HTML with Tailwind CSS but you're not using any framework?

Because https://cdn.tailwindcss.com is only advised to be used for "play" not for production.

**Here's the ABC:**

1. Assuming you already have your html site in a directory called `'site'`, create a parent directory to contain `'site'` - `'tailwind/site'`

2. Install and initial Tailwind CSS:
`cd tailwind
npm install -D tailwindcss
npx tailwindcss init`

3. Update the content array of your tailwind.config.js to:
`content: ["./site/**/*.html"]`

4. If you have any theme config go ahead to update the theme object as well

5. Create a `tw.css` file in your project root `./tailwind/tw.css` and add the following tailwind directives:
`@tailwind base;
@tailwind components;
@tailwind utilities;`
 
6. Run Tailwind build command 
`npx tailwindcss -i ./tw.css -o ./site/main.css --watch`

7. Tailwind will generate a main.css inside your /site dir. Add `<link>` it to your html and start using Tailwindcss utility classes

8. When you're done building your site, stop the tailwind cli and copy the site directory or push just the site directory to GitHub for onward deployment

9. Enjoy!
