On the 11th of January 1982 twenty-two computer scientists met to discuss an issue with ‘computer mail’ (now known as email). Attendees included the guy who would create Sun Microsystems, the guy who made Zork, the NTP guy, and the guy who convinced the government to pay for Unix. The problem was simple: there were 455 hosts on the ARPANET and the situation was getting out of control. This issue w
C10K 問題 (the C10K problem) は1999年に Dan Kegel が発表した文章、ならびにそこで提示された「問題」です。文章はその後も2000年代前半に何度か更新されているのですが、さすがに令和に読み返すと、当初の問題意識がわかりにくいところがあります。 2000年からの10年は、 ソフトウェア面では、select(2), poll(2) にかわる新しいシステムコールの実装と、それを使ったアプリケーションの普及 ハードウェア面では、x86 アーキテクチャの64ビット移行、仮想化命令の追加と、マルチコア化 さらにそこにクラウドも登場する、面白い時代でした。ここでは、それらの出来事を中心に、さらに、当時の雰囲気をつたえるような日本国内のブログやインタビュー記事をまとめることで、C10K 問題が、さまざまな側面から解決されていく流れを説明したいと思います。 書き足したいと

Why I Won't Use Next.js
You’ve got a new project to work on. Or you’ve got an existing project you’re motivated to upgrade to a more modern approach. Or perhaps you’re dissatisfied with your current modern framework or second-guessing yourself and you’re investigating alternatives. In any case, you’ve got a decision to make. There are lots of “modern” frameworks to choose from. Even if you’re not facing this choice right
As your web app matures, it becomes challenging to ensure your GUI doesn’t break with any given update. There are a lot of browsers and devices, and countless states for every one of your components. Unit tests ensure your code remains consistent, and E2E tests will ensure your system remains consistent, but neither will catch visual anomalies, layout issues, or platform compatibility issues.

The Dangerous Populist Science of Yuval Noah Harari ❧ Current Affairs
Watch videos of Yuval Noah Harari, the author of the wildly successful book Sapiens: A Brief History of Humankind, and you will hear him being asked the most astonishing questions. “A hundred years from now, do you think we will still care about being happy?” — Canadian journalist Steve Paikin, on the “The Agenda with Steve Paikin” “What I do, is it still relevant, and how do I prepare for my futu
During 2011-2012 there was a small but significant revolution in how we worked at Thoughtworks. When we needed to communicate while separated we used to do telephone meetings, but within a year the telephone disappeared and we started using video calls instead. As we got more comfortable with video, we took more opportunity to collaborate with video meetings rather than trying to get everyone toge
Python as a language is comparatively simple. And I believe, that you can learn quite a lot about Python and its features, just by learning what all of its builtins are, and what they do. And to back up that claim, I'll be doing just that. Just to be clear, this is not going to be a tutorial post. Covering such a vast amount of material in a single blog post, while starting from the beginning is p

Bicycle – Bartosz Ciechanowski
There is something delightful about riding a bicycle. Once mastered, the simple action of pedaling to move forward and turning the handlebars to steer makes bike riding an effortless activity. In the demonstration below, you can guide the rider with the slider, and you can also drag the view around to change the camera angle: Compared to internal combustion engines or mechanical watches, bicycles
The activities of the Central Intelligence Agency (CIA) in Japan date back to the Allied occupation of Japan.

－－－1980年5月19日、バージニア州の片隅にあるビルの会議室 この日、ある民間会社が経営するよくあるビルの一室に、少なくない人数の人間が集まっていた。 もしその日、その一室を覗き見る事ができたならば、それは、異様な光景であっただろう。 たとえば、普通の会議室であるのにも関わらず、ビルには空港級の警備がついていたことや、その会議室にいた人間の年齢的バリエーションなど、気になることは色々あっただろう。 そして、もし、軍隊に詳しい人間が見たならば、その一室に集まった内の一人の階級章が、現役アメリカ陸軍大将であることに気づいただろう。 しかし、何よりも異様であったのは、それらの集まった人々が、二人の外国人の老人に対し矢継ぎ早に質問を浴びせていたことだろう。 特に片方の老人はかなりの高齢で、80代も後半、もはや90代近くに見れた。 しかし、この高齢にもかかわらず、老人は質問者のエネルギーに答える

Red Hat’s commitment to open source: A response to the git.centos.org changes
I spent a lot of time walking this weekend thinking about the reaction from our industry to my last blog post. We’ve been called evil; I was called an IBM exec who was installed to turn Red Hat closed source — and that’s only the “nice” stuff. So let’s clear things up. My name is Mike McGrath, and I’m the Vice President of Core Platforms Engineering at Red Hat. I’ve been here for 16 years, and bef

Announcing the Visual Studio Code Installer for Java - Microsoft for Java Developers
It’s been almost 3 years since the first Java language server was developed during a hackathon in a small conference room at Microsoft’s Zurich office with people from Red Hat, IBM, Codenvy and Microsoft, which later became one of the most popular extensions for Visual Studio Code with more than 2.7 million installations. Since then, Visual Studio Code has gone through a thrilling journey and beco

How do you know if your models are behaving as you expect them to? What about next week/month/year when the customer (or fraudster) behavior changes and your training data is stale? These are complex challenges, compounded

Since I was unable to travel for a couple of years during the pandemic, I decided to take my new-found time and really lean into Rust. After writing over 100k lines of Rust code, I think I am starting to get a feel for the language and like every cranky engineer I have developed opinions and because this is the Internet I’m going to share them. The reason I learned Rust was to flesh out parts of t
Data Structures & Algorithms I Used Working at Tech Companies
Do you actually use data structures and algorithms on your day to day job? I've noticed a growing trend of people assuming algorithms are pointless questions that are asked by tech companies purely as an arbitrary measure. I hear more people complain about how all of this is a purely academic exercise. This notion was definitely popularized after Max Howell, the author of Homebrew, posted his Goog

What I Worked On
February 2021 Before college the two main things I worked on, outside of school, were writing and programming. I didn't write essays. I wrote what beginning writers were supposed to write then, and probably still are: short stories. My stories were awful. They had hardly any plot, just characters with strong feelings, which I imagined made them deep. The first programs I tried writing were on the
Look-up-tables, more commonly referred to as LUTs, are as old as Mathematics itself. The act of precalculating things into a row or table is nothing new. But in the realm of graphics programming, this simple act unlocks some incredibly creative techniques, which both artists and programmers found when faced with tough technical hurdles. We’ll embark on a small journey, which will take us from simp

Cameras and LensesPictures have always been a meaningful part of the human experience. From the first cave drawings, to sketches and paintings, to modern photography, we’ve mastered the art of recording what we see. Cameras and the lenses inside them may seem a little mystifying. In this blog post I’d like to explain not only how they work, but also how adjusting a few tunable parameters can produ
How a simple Linux kernel memory corruption bug can lead to complete system compromise
In this case, reallocating the object as one of those three types didn't seem to me like a nice way forward (although it should be possible to exploit this somehow with some effort, e.g. by using count.counter to corrupt the buf field of seq_file). Also, some systems might be using the slab_nomerge kernel command line flag, which disables this merging behavior. Another approach that I didn't look
