こんにちは、エンジニアの id:mp0liiu です。 8月28日(土)の Learn Languages 2021 というイベントの Language Update というセッションで@charsbarさんと一緒に2018年以降のPerl5やPerlコミュニティの最新動向について話してきたので、そのとき話した内容に補足などしつつ記事にしていきたいと思います。 配信アーカイブはこちらから見れます。 時系列 2019/5/22 Perl5.30 リリース 2020/6/20 Perl5.32 リリース 2020/6/24 Perl7の発表 2021/5/21 Perl5.34 リリース Perl5.30 の変更点 正規表現や文字周りの細かい改善などはありますが、正直めぼしい変更点が見られないです。 Perl5.32 の変更点 isa 演算子の実装 値があるクラスのインスタンスもしくはそのサブ
The forgotten mistake that killed Japan's software industry - Disrupting Japan
This is our 200th episode, so I wanted to do something special. Everyone loves to complain about the poor quality of Japanese software, but today I’m going to explain exactly what went wrong. You’ll get the whole story, and I’ll also pinpoint the specific moment Japan lost its way. By the end, I think you’ll have a new perspective on Japanese software and understand why everything might be about

Hello! I’m slowly working on explaining git. One of my biggest problems is that after almost 15 years of using git, I’ve become very used to git’s idiosyncracies and it’s easy for me to forget what’s confusing about it. So I asked people on Mastodon: what git jargon do you find confusing? thinking of writing a blog post that explains some of git’s weirder terminology: “detached HEAD state”, “fast-
Speculation in JavaScriptCore
This post is all about speculative compilation, or just speculation for short, in the context of the JavaScriptCore virtual machine. Speculative compilation is ideal for making dynamic languages, or any language with enough dynamic features, run faster. In this post, we will look at speculation for JavaScript. Historically, this technique or closely related variants has been applied successfully t

Bash Pitfalls This page is a compilation of common mistakes made by bash users. Each example is flawed in some way. 1. for f in $(ls *.mp3) One of the most common mistakes BASH programmers make is to write a loop like this: for f in $(ls *.mp3); do # Wrong! some command $f # Wrong! done for f in $(ls) # Wrong! for f in `ls` # Wrong! for f in $(find . -type f) # Wrong! for f in `find . -type f` # W

Patterns for Reactivity with Modern Vanilla JavaScript
Patterns for Reactivity with Modern Vanilla JavaScript August 21, 2023 “Reactivity” is how systems react to changes in data. There are many types of reactivity, but for this article, reactivity is when data changes, you do things. Reactivity Patterns are Core to Web Development We handle a lot with JavaScript in websites and web apps since the browser is an entirely asynchronous environment. We mu
Tooling for Tooling
We’ve seen a boom in programming language tooling in the past few years. Language servers, formatters, and linters have become commonplace in most languages. I’d call it a golden age, but I suspect this is only the beginning. Fulfilling Developer Expectations This explosion has in turn raised the bar for developer experience. No longer is it satisfactory to provide a basic syntax highlighting sche
I first got into web design/development in the late 90s, and only as I type this sentence do I realize how long ago that was. And boy, it was horrendous. I mean, being able to make stuff and put it online where other people could see it was pretty slick, but we did not have very much to work with. I’ve been taking for granted that most folks doing web stuff still remember those days, or at least t

Dear Google Cloud: Your Deprecation Policy is Killing You
God dammit, I didn’t want to blog again. I have so much stuff to do. Blogging takes time and energy and creativity that I could be putting to good use: my novels, my music, my game, and so on. But you get me riled enough, and I have to blog. Let’s get this over with, then. I’ll begin with a small but enlightening story from my early days at Google.

Perlに限らない話ですが、プログラミングをしているとセミコロンが抜けた、タイポなど些細な記述ミスでエラーが出ますよね。エラーメッセージから、原因を明確に特定できれば対処はしやすいですが、現実は、そうではなく、この辺が怪しい...くらいしか分からないことも多々。慣れたプログラミング言語でなければ、当然、土地勘がなくエラーの意味を汲み取れず、逆に慣れていれば「あーそれね」とすぐ解決に辿り着くのものです。 この記事では、Perlの初学者を対象に、Perlでよくある記述ミスとエラー、その対処方法、そして、そもそもエラーを起きにくくするための予防策をできる限り書きます。 いろんな記述ミスを紹介する前に perldiagを利用する use strict; use warnings あるいは use VERSIONを利用する can't use string as a hash ref Global

“Command line interfaces. Once that was all we had. Then they disappeared, replaced by what we thought was a great advance: GUIs. GUIs were - and still are - valuable, but they fail to scale to the demands of today's systems. So now command line interfaces are back again, hiding under the name of search. Now you see them, now you don't. Now you see them again. And they will get better and better w
*display on phone is technically 2.61x Frame size. This is the “point size” or “@1x” size of a given device. I strongly recommend designing on frames of this size for a given device. (Here’s an explanation of points vs. pixels) Export scaling. This is how much bigger to make a raster image (PNG, JPG) when exporting to take maximum advantage of the higher resolution of some devices. What size frame

Designing Effective Breadcrumbs Navigation — Smashing Magazine
Breadcrumbs UX are often neglected, but they can be extremely helpful when designing a complex navigation. We can improve them with sideways navigation, clearer breadcrumbs paths and accordions on mobile. Nobody gets particularly excited about breadcrumbs navigation. You know, those tiny little crumbles of pathways that illustrate where a user currently is in the intricate hierarchy of the website

Scott Hanselman's 2021 Ultimate Developer and Power Users Tool List for Windows
Can you believe it's been 6 years since my last Tools list? Tools have changed, a lot are online, but honestly, it's just a LOT OF WORK to do the tools list. But here's one for 2020-2021. These are the tools in my Utils folder. I made a d:\dropbox\utils folder and I added it to my PATH. That way it's on all my computers and in my path on all my computers and I can get to any of them instantly. Thi
Questionable Advice: “My boss says we don’t need any engineering managers. Is he right?”
I recently joined a startup to run an engineering org of about 40 engineers. My title is VP Engineering. However, I have been having lots of ongoing conflict with the CEO (a former engineer) around whether or not I am allowed to have or hire any dedicated engineering managers. Right now, the engineers are clustered into small teams of 3-4, each of which has a lead engineer — someone who leads the
In general, if you want a key-value storage with the highest performance, choosing the file hash database is recommended. If you need ordered access of records, choosing the file tree database is recommended. If you need scalability of ordered databases, choosing the file skip database is recommended. If you need extreme performance, the on-memory hash database and the on-memory tree database are
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.

Knowing how to profile a React application to improve real-world performance is a good tool in any front-end developer’s toolkit. The Profiler API allows us to do just that with insights on why and how long our components are rendering for. We can use the profiling data to find unnecessary and expensive renders that may be impacting performance negatively. Thankfully, it’s not that complicated. Le

If this target is provided by LLVM, LLVM may have the target as an experimental target, which means that you need to use Zig-provided binaries for the target to be available, or build LLVM from source with special configure flags. zig targets will display the target if it is available.

Design tool canvas handles
Design tools often pack a lot of functionality around the bounding box of selected objects. Some of this functionality is represented by handles or icons, but a lot of it is hidden. This can make learning the behaviour and interacting with objects pretty tricky. The only way to know if you can perform an action is to hover near the edge of a selected shape and note cursor changes. It’s like inspec
Extreme HTTP Performance Tuning: 1.2M API req/s on a 4 vCPU Instance
The main takeaway from this post should be an appreciation for the tools and techniques that can help you to profile and improve the performance of your systems. Should you expect to get 5x performance gains from your webapp by cargo-culting these configuration changes? Probably not. Many of these specific optimizations won't really benefit you unless you are already serving more than 50k req/s to
