Attached is my attempt at making a small toy S3 client without any other dependency besides libcurl and OpenSSL. Was tested mainly on MinIO (RIP) locally, so I would expect some bugs when using it against AWS, although I was able to play with it on some open access buckets Be aware that I am not a C++ programmer and this project was indeed done to learn a bit of C++ myself :') Feedback on any of the code, either on gtest, or the benchmarking section or the core itself is welcome!

Microsoft is preparing to lay off a significant chunk of its Xbox division and is reevaluating the plans for its next-generation Project Helix console. It's apparently also considering dramatically restructuring its relationship with Xbox, and hasn't ruled out spinning it off into a separate company. A new report from The Information suggests that Microsoft has […]

I’ve struggled with insomnia since I was very young. Like many chronic overthinkers, I tend to fall asleep best when my mind is occupied by something else, such as podcasts, YouTube compilations, or my personal favorite: rain sounds. But earbuds can be uncomfortable, and playing audio out loud isn’t exactly considerate when I’m staying at […]

If you’re planning on traveling anytime soon, Bose’s second-generation QuietComfort Ultra headphones are a great companion for long flights and train rides. Not only do they offer excellent noise cancellation, but they also retain the foldable design of their predecessor, making them easy to pack in a carry-on. They’re even easier to recommend today, now […]

GSoC 2026 | CircuitVerse × Canvas LMS LTI 1.3 Integration If Week 1 was about getting familiar with the codebase and understanding what needed to be built, Week 2 was about learning the hard way that writing code is only half the job. The other half — the messier, more humbling half — is getting that code accepted by the people who actually maintain the project. This week was full of detours, rejected pull requests, reviewer feedback that stung a little, and a surprisingly frustrating fight with a two-letter word in Ruby. But by the end of it, I had something real to show: a clean, reviewed, and submitted change to CircuitVerse that lays the foundation for the entire LTI 1.3 integration. Let me walk you through it. A Quick Refresher: What Are We Building? CircuitVerse is an open-source platform where students can build and simulate digital circuits right in their browser. The project I'm working on aims to connect CircuitVerse with Canvas, one of the most widely used Learning Management Systems (LMS) in universities around the world. The technology that makes this connection possible is called LTI — Learning Tools Interoperability. Think of it as a universal plug that lets any educational tool (like CircuitVerse) slot into any LMS (like Canvas) so that students can log in once, get assignments, submit work, and have their grades flow back automatically — all without leaving their course page. There are two versions of this plug: LTI 1.1 , which is old and uses a simpler (but outdated) security mechanism, and LTI 1.3 , which is newer, more secure, and what Canvas actually recommends today. My job is to bring CircuitVerse fully up to LTI 1.3 standards. Monday–Tuesday: A Pull Request That Taught Me to Read Diffs I started the week with what I thought was a solid pull request (PR) — a fix for a bug in CircuitVerse's existing LTI 1.1 grade passback feature. "Grade passback" is the process where CircuitVerse sends a student's score back to Canvas after they complete an as

How a PHP SDK Can Save You Hundreds of Lines of API Integration Code Most APIs provide documentation, examples, and maybe even a Postman collection. That's usually enough to get started. But once your application grows, you'll quickly discover that working directly with HTTP requests introduces a surprising amount of repetitive code. You end up writing the same things over and over: Authentication headers Request serialization Response parsing Error handling Pagination logic DTO mapping This is exactly why SDKs exist. In this article, we'll look at how a PHP SDK can simplify API integrations and reduce maintenance costs over time. The Hidden Cost of Direct API Calls Let's imagine you're integrating a URL shortening API. A typical implementation might look like this: $client = new GuzzleHttp\Client (); $response = $client -> post ( 'https://example.com/api/links' , [ 'headers' => [ 'X-Api-Key' => $apiKey , 'Content-Type' => 'application/json' , ], 'json' => [ 'url' => 'https://example.com' ] ] ); $data = json_decode ( $response -> getBody () -> getContents (), true ); This doesn't seem bad. Now repeat it for: Create link Update link Delete link Get link List links Create group Update group Get profile Eventually your codebase becomes filled with API boilerplate. The business logic becomes harder to see because it's buried under HTTP implementation details. What a Good SDK Does A well-designed SDK abstracts repetitive tasks and exposes a clean programming interface. Instead of dealing with HTTP requests directly, developers work with resources and objects. For example: $link = $client -> links () -> create ([ 'url' => 'https://example.com' ]); This is easier to read and easier to maintain. The SDK becomes responsible for: Authentication Request building Validation Serialization Response mapping Exception handling Consistent Error Handling One common problem with raw API integrations is inconsistent error handling. Without an SDK, every request may need its own validat

If you've ever tried building a sports betting application, odds tracker, arbitrage scanner, value betting tool, or sports analytics dashboard, you've probably experienced the same thing: You start with the exciting part. The idea. The algorithm. The UI. The business logic. And then reality hits. The Hidden Problem Nobody Talks About Most developers assume the hardest part of a betting-related project is the prediction model or arbitrage logic. In practice, the real challenge is data infrastructure. Before your project can calculate anything, you need: Live events Accurate odds Multiple bookmakers Consistent market structures Historical updates Reliable refresh rates And suddenly your "weekend project" turns into a full-time data engineering job. The Scraping Trap Most developers begin by scraping bookmaker websites. At first it seems simple: Open DevTools Find the API request Parse the response Save the data Done, right? Not quite. Within a few weeks you'll likely encounter: Changed endpoints Rate limits Cloudflare protection Different JSON formats Missing markets Broken parsers Increased maintenance costs Instead of improving your product, you're fixing scrapers. Again. And again. And again. Every Bookmaker Speaks a Different Language Let's say you want to compare odds from five sportsbooks. You quickly discover that every provider structures data differently. One bookmaker might return: { "home" : "Liverpool" , "away" : "Arsenal" } Another might return: { "team1" : "Liverpool" , "team2" : "Arsenal" } A third one could use: { "participants" : [ "Liverpool" , "Arsenal" ] } Now multiply that problem across: dozens of bookmakers hundreds of leagues thousands of events You end up spending more time normalizing data than building features. Real-Time Data Changes Everything Many projects work perfectly during testing. Then live data arrives. Odds can move multiple times within a minute. If your system refreshes too slowly: arbitrage opportunities disappear alerts become
