  • ISUCON12予選 スコア4位相当でしたが失格になりました - Classi開発者ブログ

    TL;DR こんにちは。Classi開発部のminhquang4334です。 今年は開発支援部のhenchiyb先輩と一緒に 2回目でyasuoチームとして ISUCON12の予選に参加しました (参考: 1回目で参加したブログ)。 最終結果は予選通過スコアを超えて、 4位/700チーム相当でしたが、SecurityGroupの TCP:8080 ポートがオープンされていたため、レギュレーションに引っ掛かって失敗しました。 以下のチームは予選通過スコアを記録していましたが、追試において失格となっています。 yasuo 環境チェックにおいて、SecurityGroupの TCP:8080 ポートがオープンされていた このブログでは積極的に自分の感想やチームがやったことを共有したいと思っています。 全体的な感想 正直、悲しい気持ち半分、嬉しい気持ち半分で戸惑っています。予選の実施前には、ここま

          👋 This page was last updated ~3 years ago. Just so you know. In the two years since I’ve posted I want off Mr Golang’s Wild Ride, it’s made the rounds time and time again, on Reddit, on Lobste.rs, on HackerNews, and elsewhere. And every time, it elicits the same responses: You talk about Windows: that’s not what Go is good at! (Also, who cares?) This is very one-sided: you’re not talking about th

When I was first learning Go, I already knew several other programming languages. But after reading an introductory book and the language specification I felt like I really didn’t know enough about Go to use it for real world work. I felt I’d probably need to fall into many traps before

                  One of the key benefits of open-source software is that anyone can read the source code and inspect what it does. And yet most software, even open-source software, is downloaded in the form of compiled binaries, which are much more difficult to inspect. If an attacker wanted to run a supply chain attack on an open-source project, the least visible way would be to replace the binaries being served

                    Introduction to Go 1.19 The latest Go release, version 1.19, arrives five months after Go 1.18. Most of its changes are in the implementation of the toolchain, runtime, and libraries. As always, the release maintains the Go 1 promise of compatibility. We expect almost all Go programs to continue to compile and run as before. Changes to the language There is only one small change to the language, a
