Don't Aim for Quality, Aim for Speed

Hits-of-Code Instead of SLoC

www.yegor256.com/2014/11/14/hits-of-code.html

How about we measure the amount of times programmers touch the lines. Instead of counting the number of lines we’ll count how many times they were actually modified—we can get this information from Git (or any other SCM). The more you touch that part of the aircraft—the more effort you spent on it, right?

I called it Hits-of-Code (HoC) and created a small tool to help us calculate this number in just one line.

What a nice idea! I installed this program and ran it on Betula and Mycorrhiza codebases. For Betula it's 26350 HoC, for Mycorrhiza it's 137208 HoC. Yeah, Betula is still comparatively young! Hey, what about Mycomarkup? 23443. Oh wow, just a little less than Betula. I expected a small number.

EditorConfig

editorconfig.org

EditorConfig helps maintain consistent coding styles for multiple developers working on the same project across various editors and IDEs. The EditorConfig project consists of a file format for defining coding styles and a collection of text editor plugins that enable editors to read the file format and adhere to defined styles. EditorConfig files are easily readable and they work nicely with version control systems.

Trunk Based Development

trunkbaseddevelopment.com

A source-control branching model, where developers collaborate on code in a single branch called ‘trunk’ *,
resist any pressure to create other long-lived development branches by employing documented techniques. They
therefore avoid merge hell, do not break the build, and live happily ever after.

Interning strings in Go

commaok.xyz/post/intern-strings

In Go, a string is a (possibly empty) immutable sequence of bytes. The critical word here for our purposes is immutable. Because byte slices are mutable, converting between string and []byte generally requires an alloc and copy, which is expensive.

What if such conversions were cached? That would make comparing strings so much faster!: two integer comparisons (len and ptr). This article explains how this approach could be implemented.

A library implementing this:

It looks pretty small and simple. Despite having only 81 stars, it is used by 67.4k GitHub packages. Transitive dependencies. Found it at work accidentally. OpenSource woes.

Wrapping Errors in Go - How to Handle Nested Errors

blog.boot.dev/golang/wrapping-errors-in-go-how-to-handle-nested-errors

By wrapping errors and building well-formatted error messages, we can keep better track of where errors are happening. I often just add the name of the function being called to my error messages, but we can make the message say whatever we want. For example, I’ll often include parameter information in the error so I know which inputs caused the error.

Don’t prefill config files

www.makeworld.space/2024/02/no_prefill_config.html

The biggest design mistake I made with Amfora, my first community open source project, was autogenerating config files. On startup, the application looks for a config file, and creates one if it doesn’t exist, full of all the application defaults. At the time, I thought this was great, as it documents all the existing options, and makes them very visible to the user in case they want to change them. In the end, this decision created a lot of headaches and is not something I’d ever do again.

makeworld is right! I had the same problem in Mycorrhiza but didn't suffer great consequences because the configuration design didn't change much.

Some activities are harder than others

alexschroeder.ch/view/2024-01-31-activities

Alex tells us that, for him, baking and cooking are easier than programming and soldering, because the errors there average out. As for me, this is completely inverse.

In programming, an error never fixes itself. You can observe it and fix it, you can write tests. You can run the program multiple times. It's you who fixes it, and you can understand how it's done. It's measurable!

Meanwhile, cooking is a nightmare. Burning something is routine for me. Is that too much or too little oil? For how long do I fry? What do I do with these spices? Do they really affect the taste? And to observe something, I can't rely on symbolic things like text. No, I have to look (is this color good? No idea!), smell (as if I know the difference) and taste (nothing more inaccurate).

I'm happy when something can be cooked with a timer. 15 min for buckwheat? I'm in. I'm more happy when the time is short. 4 min for this thin kind of spaghetti? Already boiling water!

I mean, even boiling water is not simple. My parents told me to wait until the correct bubbles appear. I'm waiting for the scary ones. Also, salt is supposed to make it boil faster. How much salt do I add?

And I didn't even talk about plants, which Alex also considers easy. They're not 😭

Реальный Windows. Пишем realtime под окошками

Результат всего этого счастья нужен в режиме реального времени и крайне важен. Пропускать нельзя ни одного замера, потому что основную работу по анализу данных исследователи выполняют после окончания эксперимента. Поэтому всё это богатство данных, помимо показа на экране, придётся записывать на жёсткий диск. Все 1,3 гигабайта данных в секунду. И потом читать в Matlab'е, NeuroExplorer'е или другой программе. Система, которая сохраняла 99,99999% данных, не прошла контроль качества и была забракована, потому что теряла до 13 тысяч замеров каждую секунду.

В комментах пишут ещё:

я долго мечтал войти в медицину и больше 5 лет пытался работать с врачами. в итоге пришёл к печальному выводу, что это очень трудные во взаимодействии люди. не умеют мыслить структурно, стараются постоянно держать лицо, привыкли к строгой иерархии и за её пределами работать не обучены. так что непреодолимое и авторитарное требование виндовса тут неудивительно.

Статью написал Alex Hitech, что уже показатель качества. И комментарии у него заводные:

Мозг необязательно должен быть человеческим. Большинство исследований мозга выполняются на крысах и мышах, — их мозг очень похож на наш, а стоят они не в пример дешевле.

Not only did his compiler know it was compiling the login function and inject a backdoor, but it also knew when it was compiling itself and injected the backdoor generator into the compiler it was creating. The source code for the compiler thereafter contains no evidence of either virus.
