Hello! I posted a comic on Mastodon this week about what’s in the .git directory and someone requested a text version, so here it is. I added some extra notes too. First, here’s the image. It’s a ~15 word explanation of each part of your .git directory. You can git clone https://github.com/jvns/inside-git if you want to run all these examples yourself.

Webpack 4 was released in February 2018. Since then we shipped a lot of features without breaking changes. We know that people dislike major changes with breaking changes. Especially with webpack, which people usually only touch twice a year, and the remaining time it "just works". But shipping features without breaking changes also has a cost: We can't do major API or architectural improvements.
1行あたりの文字の表示数を多くすると文章が速く読めるようです。 レディング大学のポール・コラーズ氏（Paul Kolers）らの研究チームは、一行当たりの文字数と読む速さの関係性を検討しています。 結果、一文当たりの文字数が多いほど、読み終えるまでにかかる時間が短くなる現象が確認されました。 スマホやkindleで文章を読むときに縦ではなく横向きにし、一行当たりの文字数を多くすることで読み終わる時間を短くすることができるかもしれません。 また表示の文字の大きさを小さくし、一文当たりの文字数を多くすることでも早く読めるようになります。 この一行当たりの文字数を多くすることで読むスピードが速くなる現象は、日本語の文章を対象にした研究でも確認されています。 この研究の初期の報告は、学術誌「Human Factors: The Journal of the Human Factors and Er
論文のrejectという希望 - 人間とウェブの未来
ここ2、3年で目標としていた、IEEE Computer SocietyのFlagship Conferenceの一つとされているCOMPSAC 2020のメインシンポジウムに、ファーストオーサの論文がフルペーパーで採録されました。 送られてきたメールによると、今回のメインシンポジウムのフルペーパ採録は24%以下ということで、昨年の250本程度の投稿論文があることを考えると、全体のフルペーパ採録は60本程度になるかと予想できます。去年はCOMPSACのメインシンポジウムにショートペーパとしてファーストオーサの論文が1本採録、ラストオーサの論文がショートペーパで1本、併設ワークショップに1本という実績でした。 さらに、2年前は未だに当時のショックを覚えているぐらいに、メインシンポジウムでの査読でフルボッコの査読結果を頂き、なんとか気を持ち直してワークショップに通すことができた、ぐらいの実績で

WhyReact.md I heard some points of criticism to how React deals with reactivity and it's focus on "purity". It's interesting because there are really two approaches evolving. There's a mutable + change tracking approach and there's an immutability + referential equality testing approach. It's difficult to mix and match them when you build new features on top. So that's why React has been pushing a

A no-go fantasy: writing Go in Ruby with Ruby Next—Martian Chronicles, Evil Martians’ team blog
Ruby is awesome. We love its readability, flexibility, and developer-centric nature. Still, here at Mars, we also love Go because it has its own sense of simplicity and magic, too. Simply put, Go holds advantages over Ruby in some aspects: it’s faster, statically typed, and comes with cool concurrency primitives out of the box. This being said, some intrepid readers might find themselves grappling

Python is among the one of the most popular programming languages, yet it's generally not the first choice when speed is required.
