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
紅白歌合戦見直しました。 正味、「紅白をフェスにする」という前回の方針は凄い勢いでハマり、正味近年では最強の紅白になったわけですが、今回は恐らくもう去年のアレを越えようという方針ではなかったと思います。 少なくとも「2020東京オリンピック」にまつわる演出という「枷」があり、そういうところには持っていけなかったのではないかと。 見た限り、去年のようなすっ飛び方はなく、既存の紅白としての演出の延長線上でどこまでやれるかという感じに見受けました。 正直、ウサイン・ボルトが出てくる文脈などは全体としてもよくわからず、本当に「2020東京オリンピック」に引っ張られてしまったな、と。 結果として、演出の部分ではOfficial髭男dismに「ルネッサンス」をやらせ、その後綾瀬はるかに「樋口カッター」やらせたところが多分今回の白眉。 あと、出演者名のテロップの下に変な豆知識入れるの、それはテレビ東京の
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
Broken Ownership
Have you been in any of these situations? Managers make decisions that’s out of their leagues and everyone else in the team ends up paying for it. Knowledgeable people passively observe without bothering to contribute. Sometimes they are denied access to the room. Developers act like code monkeys, throwing the code over a metaphorical wall for the QA to test and “DevOps” to run. In “you build it,

Don't Use Kubernetes, Yet
Early-stage startups shouldn't run on Kubernetes yet. But eventually, growth-stage and large companies should be running on Kubernetes in some form. Kubernetes Maximalism doesn't mean one-size-fits-all. Infrastructure should progressively grow with your workloads and team. How can you choose the right technology now so that you can maximize growth and minimize pain later when you inevitably outgro
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

Docker is deleting Open Source organisations - what you need to know
Coming up with a title that explains the full story here was difficult, so I'm going to try to explain quickly. Yesterday, Docker sent an email to any Docker Hub user who had created an "organisation", telling them their account will be deleted including all images, if they do not upgrade to a paid team plan. The email contained a link to a tersely written PDF (since, silently edited) which was mi

ML Ops: Machine Learning as an Engineering Discipline
So, your company decided to invest in machine learning. You have a talented team of Data Scientists churning out models to solve important problems that were out of reach just a few years ago. All performance metrics are looking great, the demos cause jaws to drop and executives to ask how soon you can have a model in production. It should be pretty quick, you think. After all, you already solved

Linux Crisis Tools
(This is based on Table 4.1 "Linux Crisis Tools" in SysPerf 2.) Some longer notes: [1] bcc and bpftrace have many overlapping tools: the bcc ones are more capable (e.g., CLI options), and the bpftrace ones can be edited on the fly. But that's not to say that one is better or faster than the other: They emit the same BPF bytecode and are equally fast once running. Also note that bcc is evolving and
We want the default build output of Next.js to work well when self hosting, and also well on Vercel. And guess what? They're the same output. Well, almost. Let me clarify. It took us a while at Vercel to figure out the correct format and boundary between open source framework and infrastructure platform. Our philosophy is called framework defined infrastructure. And critically, the specification t
How NAT traversal works
* can theoretically exist, but don't show up in the wild Once broken down like this, we can see that cone-ness isn’t terribly useful to us. The major distinction we care about is Symmetric versus anything else — in other words, we care about whether a NAT device is EIM or EDM. While it’s neat to know exactly how your firewall behaves, we don’t care from the point of view of writing NAT traversal c

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.

This article is about what it would mean to add generics to Go, and why I think we should do it. I’ll also touch on an update to a possible design for adding generics to Go. Go was released on November 10, 2009. Less than 24 hours later we saw the first comment about generics. (That comment also mentions exceptions, which we added to the language, in the form of panic and recover, in early 2010.)

Parse, don’t validate
Historically, I’ve struggled to find a concise, simple way to explain what it means to practice type-driven design. Too often, when someone asks me “How did you come up with this approach?” I find I can’t give them a satisfying answer. I know it didn’t just come to me in a vision—I have an iterative design process that doesn’t require plucking the “right” approach out of thin air—yet I haven’t bee
Then, as discharged passengers made their way into the Tokyo subway system, derision grew. Waves of death were predicted. They did not eventuate. Attention then shifted from Japan to South Korea, Italy, Europe and the United States. Only in late March did Japan start to enter an unwanted limelight again. The Tokyo governor’s March 25 announcement of “emergency measures” was in fact largely an urge
