Our team optimized and rebuilt a simulator for the futures and options (F&O) exchange.

---

## What?

The F&O exchange is a massive software product with many moving parts.  Cloud computers run multiple copies of the exchange simultaneously: some make up the real exchange that customers use, but most are just simulations.  Software engineers often use simulations to verify their work and try new things.


![Computers run code to simulate a program.](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/e2sywgipj3j0te3g9yc7.png)

Simulations are VERY useful for lots of reasons.  We'll explore one in particular.

## Quality Assurance

All customers ***hate*** buying shitty software, so it's mission-critical to fix every bug before selling your app or service.  But the futures&options exchange is *massive*, and we're updating it all the time!  How do you manage to catch all the bugs in such a big piece of software?

Automated testing is the answer.

![A series of testing suites validates market behavior using simulations.](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/jzmujtumat3hrxpox1sz.png)

The F&O exchange is rigorously vetted by automated testing suites.  Each suite is powered by its own simulation, like in the picture.  Suites interact with the simulation and watch its behavior for defects.  This process automatically catches bugs, and it works quite well.

> My role was to build a testing suite that behaves like a trader.  The pretend-trader reads English descriptions of expected market behavior, then it trades on the simulated F&O exchange to ensure it's behaving as described.

## Simulations for Sale

The process of creating simulations has been automated for quite some time, since so many of them are needed for automated testing.  This production process is very intricate and brittle.

Here is the visualized production line for mass-producing F&O simulations:

![A long and convoluted process to creating one simulation for the F&O exchange](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/dz9s7olo7n7rse8cyeh4.png)

These simulations are bulky and expensive since producing one is complicated.  Developers spend a very long time reading deployment strategies, just trying to understand how simulations are made.  Part of our team's work is to de-clutter the process of deploying a simulation.  That way, (a) simulations are cheaper to produce, and (b) it's easier for devs to understand them.

## What's Next

I have hopes, goals, and aspirations for the project, but it's technically company property so I don't want to accidentally get in trouble.  With that being said, a one-click deployment process would be sick.  Just push a single button, and ***bam!*** - you have a live, running F&O exchange allllllll to yourself.  Kinda like a poke-ball for the F&O exchange.

Exploring DNS: Understanding the Communication Between Domain Names and IP Addresses!

Ever wondered how, when you type "example.com" in your browser, what happens behind the scenes? 🌐 That's where DNS (Domain Name System) steps in.

DNS, which stands for Domain Name System, plays a crucial role in facilitating user access to websites by translating domain names into IP addresses.
When a user enters a website like example.com in the search bar, the DNS server performs the essential task of converting the website name into its corresponding IP address and promptly delivers it to the client. This IP address enables the web browser to establish communication with the web server, ultimately retrieving the requested data.

Building a data stack with Kubernetes and Argo CD
Tags: kubernetes, database, devops, opensource
Published: 2023-12-05 06:22:05

I have been working on ClickHouse and Kubernetes for several years at my current company, Altinity. Earlier this year we found out about Argo CD from one of our customers and have been learning how to use it to stand up analytic database stacks. 

In case you are not familiar with Argo CD, it provides a way to define Kubernetes applications, store them in GitHub, and deploy/update them in live Kubernetes clusters. It's addictive once you get used to it. Based on the experience, I wrote a tutorial on how to set up ClickHouse clusters on Kubernetes.

[Bring up ClickHouse on Kubernetes with Argo CD](https://altinity.com/blog/bring-up-clickhouse-on-kubernetes-with-argo-cd)

One of the things we picked up on quickly is that Argo is very powerful to use for building stacks, but there's a learning curve. It's extremely helpful to see working Argo CD code to understand how to use it effectively. We are planning to build out the project the article references into a proper blueprint for analytic stacks. 

I would love to hear what people think of this tutorial and more generally how you are building stacks on Kubernetes. Are you using Argo CD? If not, what are you using? Flux? Terraform? Mega-scripts of death?

How to use React <Suspense>
Tags: react, javascript, frontend
Published: 2023-11-30 10:10:13

React Suspense is a feature introduced in React to simplify the handling of asynchronous operations like data fetching or code splitting. Here's a basic guide on how to use it:

1. **Code Splitting with `React.lazy`:**
   - Use `React.lazy` to dynamically import a component. This helps split your code into chunks that are loaded only when needed.
   ```javascript
   const SomeComponent = React.lazy(() => import('./SomeComponent'));
   ```

2. **Wrap with `<Suspense>` Component:**
   - Wrap the lazily loaded component with the `<Suspense>` component.
   - Provide a fallback UI to display while the component is being loaded.
   ```jsx
   import React, { Suspense } from 'react';

   function MyComponent() {
     return (
       <Suspense fallback={<div>Loading...</div>}>
         <SomeComponent />
       </Suspense>
     );
   }
   ```

3. **Handling Data Fetching:**
   - For data fetching, you can use libraries like Relay or others that support Suspense.
   - Wrap the component that performs data fetching inside `<Suspense>`.
   - The fallback will be displayed until the data fetching is complete.

4. **Error Boundaries:**
   - Use error boundaries to handle errors in asynchronous code. Suspense boundaries only handle loading states, not errors.
   - Wrap your Suspense component in an error boundary to catch and handle errors gracefully.

5. **Server Side Rendering (SSR):**
   - If using SSR, ensure your server-rendering environment supports Suspense.
   - Libraries like Next.js have built-in support for Suspense with SSR.

6. **Use with Concurrent Mode (Experimental):**
   - Suspense works best with React's Concurrent Mode, which is still experimental.
   - Concurrent Mode allows for more fine-grained control over the rendering process, improving performance for complex applications.

7. **Testing:**
   - When writing tests for components using Suspense, make sure to mock the loading state and test the fallback UI.
   - Also, test the loaded state to ensure the component renders ``correctly after the asynchronous operation completes.

Project Five: Star Rating
Tags: webdev, beginners, challenge, codingquokka
Published: 2023-12-05 06:00:00

How many stars would you give to a rating component? I think it deserves all of them!

Think about it: from e-commerce websites to mood diaries those shiny little helpers make a day a little bit brighter.

Ready to take it on?

## Star Rating: requirements and recipe

> As a user I want to be able to see a visual representation of a rating, so that I can make a quick judgement just by glancing on it.

Here's an example of how it can look like: ⭐⭐⭐⭐⭐.

Though just emojis are unfortunately not enough to meet all the requirements:

### Requirements
1. It should be possible to render 1,2,3,4 and 5 stars ratings
2. It should be possible to render ratings in between, rounded to a half (e.g. 4.5)
3. Both filled and empty stars should have sufficient contrast ratio
4. Rating should have a title, label or a screen reader specific text
5. Rating markup should include *microdata* for search engine snippets

### Recipe
1. Create a star
2. Create three versions of it: filled, empty and half-filled (or half-empty, depending on your preference 😁)
3. Create a static markup for 2.5
4. Make sure that markup matches all requirements, including accessibility ones
5. Write a function that would round a rating to the nearest available value and render it
6. Sprinkle with your favourite framework or leave it as is
7. Give yourself a 5 star rating!

### Hints

There are several ways to draw a star with HTML: for example one could use an image, inline SVG or pure CSS. 

## Hard mode: Star rating input

Now that you have a way to display a rating it would make sense to create an input so that you could get those ratings in when needed.

The hardest part about an input like this is to make it accessible and there's nothing better for it than a built-in HTML element. Unfortunately, there isn't one that would give the visual representation of lined up stars.

With accessibility in mind, think about all the visual feedback you'd like to give users: should you light the stars on hover? Maybe also handle the case when the user is changing one rating to another.

Have fun! And it if's not wild enough, you can join me in implementing a terminal-based star rating input (there's a special sequence of characters you could print to *stdout* to enable mouse input that I really want to try out 🤩). 

Share your creations and feedback and see you tomorrow!

Liked the idea a lot and would love to have it all year long?
