PostgREST is a standalone web server that turns your PostgreSQL database directly into a RESTful API. The structural constraints and permissions in the database determine the API endpoints and operations.

Sounds like a way to write less code. I skimmed through the reference, looks cool. PostgREST is written in Haskell for some reason though.

ntfy is a simple HTTP-based pub-sub notification service. It allows you to send notifications to your phone or desktop via scripts from any computer, and/or using a REST API.

curl \
  -d "Backup successful 😀" \

Free notifications!

UPD. Used it in my SystemD service files to notify me of service restarts. It was extremely easy to do so. Will use it for now, until I migrate to a proper monitoring system.

This article made me very angry. It's written very misleadingly, it's full of lies. The proposed language offers too much decisions to the config designer (all of the decisions that matter, actually). Nevertheless, there are some ideas I want to mention here:

• Not having primitive types beside strings is good. I'd also keep lists and dictionaries (not the way they made it, but the way it should be). Numbers, dates, booleans, all of this is a mess.

• So, empty config or no config file at all must be a valid configuration.

And it's kinda neat how they find connections between category theory and configuration languages.

What I've learned from ten years working on projects like this

Given that events play such a central role in event-driven architecture, there’s an astonishing lack of agreement on what should be contained in an event. This may be rooted in the fact that, depending on your perspective, events fulfill different purposes.

Isometric games are extremely popular. Let's learn the theory behind isometric projection and how it is used by gamedevs to write isometric-looking games.

As game developers, we can learn a lot from the past. Let's look at the history of game consoles to understand the driving forces that helped shape the modern gamedev technologies we use today.

Идемпотентность — звучит сложно, говорят о ней редко, но это касается всех приложений, использующих API в своей работе. Меня зовут Денис Исаев, и я руковожу одной из бэкенд групп в Яндекс Такси. Сегодня я поделюсь с читателями описанием проблем, которые могут возникнуть, если не учитывать идемпотентность распределенных систем в своем проекте.

Giving write access to your contributors might motivate them to do more. Super cool!

Computers are amazing. So why is software so terrible?

Applying The Blue Angel Criteria To Free Software

The 1OPS principle is the single principle that had the biggest impact in my entire coding career. I gave some hints about it in a previous post, but I was suggested that it might warrant a post on its own to go more in depth.

There is a single advice I would give to anyone writing software, and specially to great devs : Always optimize your code for your most junior developers. I agree that it is not a very popular advice, but it is the one that, in my experience, give the biggest bang for the buck.

When project scope is perfectly decomposed and management rules are clear and strict, speed of delivery is the virtue, not the quality.

It is very important to conduct regular code reviews within every software team, but it is not so easy to do them right; here are a few typical pitfalls.

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 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.

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.

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.

Innovation tokens and whatnot.

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.

Programmers are the builders of ontologies.

Apple released a language for configs. It's well-designed, take a look. Has Go bindings. I would've considered it if I needed a config language.

Гришаев решил корабль Тезея.

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.

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 😭
