Several weeks ago, the .NET Blog featured a post What is .NET, and why should you choose it?. It provided a high-level overview of the platform, summarizing various components and design decisions, and promising more in-depth posts on the covered areas. This post is the first such follow-up, deep-diving into the history leading to, the design decisions behind, and implementation details of async/a
Hi everyone, Yesterday (2021-03-28) two malicious commits were pushed to the php-src repo [1] from the names of Rasmus Lerdorf and myself. We don't yet know how exactly this happened, but everything points towards a compromise of the git.php.net server (rather than a compromise of an individual git account). While investigation is still underway, we have decided that maintaining our own git infras
The Story of the PS2’s Backwards Compatibility From the Engineer Who Built It
As the PlayStation 2 turns 20 in Japan on March 4, followed by Europe and North America later in the year, game outlets of all stripes will undoubtedly be trotting out lists and retrospectives commemorating one of the most culturally significant and successful consoles to ever be produced. Although much of that attention will likely be focused on the many unique and diverse games that helped make

This is the first of several posts exploring how git works under the hood. While lots of programmers are familiar with using git, I wanted to do a deep dive into how git is implemented. git employs many clever ideas to optimize common version control operations. I'm a big fan of trying to understand software by playing around with it rather than reading lots of documentation. To that end, I've wri

Rootless containers is a new concept of containers that don’t require root privileges in order to formulate. Many solutions ha
IntroductionWhen I started up my journey into the fabulous world of Flutter beginning 2018, very little documentation could be found on Internet compared to what exists today. Despite the number of articles that have been written, very few talk about how Flutter actually works. What are finally the Widgets, the Elements, the BuildContext ? Why is Flutter fast and why does it sometimes work differe
If you combine this with the Unicode table, you’ll see that English is encoded with 1 byte, Cyrillic, Latin European languages, Hebrew and Arabic need 2, and Chinese, Japanese, Korean, other Asian languages, and Emoji need 3 or 4. A few important points here: First, UTF-8 is byte-compatible with ASCII. The code points 0..127, the former ASCII, are encoded with one byte, and it’s the same exact byt

Why You Shouldn't Buy a MacBook With Only 256GB Storage
How much storage do you need for a MacBook? Is 256GB of storage enough for a MacBook Pro or Air? Let's find out. When Apple unveiled the first MacBook Pro with Retina display in 2012, it shipped with 256GB of flash storage at a minimum. Nearly a decade later, in 2022, the entry-level 13-inch MacBook Pro (as well as the MacBook Air) still only includes 256GB of storage, unless you upgrade it. Meanw

Let's build a Chrome extension that steals everything

To prove it, let’s build a Chrome extension that steals as much data as possible. I’m talking kitchen sink, whole enchilada, Grinch-plundering-Whoville levels of data theft.

The complexity of writing an efficient NodeJS Docker image - Specfy
Docker is an invaluable tool for managing containers, but it can be challenging to grasp its inner workings, especially for newcomers.

One of the first XKCD comics to go viral was this one, #303: Today, the web developer version would be “my site’s building” and they would be playing swords in VR. Sites take time to build these days. A large Next.js 11 site will take several minutes to build. This is wasted time in the development cycle. Build tools like Vite or Turbopack highlight their ability to get this number down. But the d

It may not be possible for us to ever reach empirical definitions of "good code" or "clean code", which means that any one person's opinions about another person's opinions about "clean code" are necessarily highly subjective. I cannot review Robert C. Martin's 2008 book Clean Code from your perspective, only mine. That said, the major problem I have with Clean Code is that a lot of the example co

I first learned Kubernetes ("k8s" for short) in 2018, when my manager sat me down and said "Cloudflare is migrating to Kubernetes, and you're handling our team's migration." This was slightly terrifying to me, because I was a good programmer and a mediocre engineer. I knew how to write code, but I didn't know how to deploy it, or monitor it in production. My computer science degree had taught me a

By Francesco Bertolaccini You’ve reached computer programming nirvana. Your journey has led you down many paths, including believing that God wrote the universe in LISP, but now the truth is clear in your mind: every problem can be solved by writing one more compiler. It’s true. Even our soon-to-be artificially intelligent overlords are nothing but compilers, just as the legends foretold. That sma

Avoiding the expensive commit parsing results in a nice constant factor speedup (about 6x in these examples), but we need something more to get even better performance out of certain queries.
