For the last year, strange things were happening with Medium. Many people complained that Medium hides everything behind the paywall, but I didn’t get it, until recently… but let us start from beginning.

My first blog was a static page on GitHub, written in Markdown. They were deploying through Jekyll. I love everything about Jekyll and GitHub Pages, but when you need to make drafts, share them with your technical editor, got comments on your writing style, etc… it becomes harder to handle all of that, since these are just plain Markdown files.

While looking for other solutions, I’d found Medium a few years ago. It was a breakthrough. It has a WYSISYG editor, you can make drafts and share them with people, getting the feedback as comments to your lines. You were fixing those issues and “Publish”. Decent!

Everything was great until they had introduced paid membership. They were selling this with a motto “let your posts make you money” or something like that. It was optional, so I just refused and forgot about it. You still can read other’s people posts, write your own, so what is the difference, right?

Recently, I have published an article where I describe a few tricks about how to migrate your project from multi-repository to mono-repository. Some of you really appreciated the topic:

However, some of you wanted more details about the build process itself. So, I have written about that in depth.

We had a lot of repositories for different services. There are 20K+ commits in 15+ repositories. Each repository has its own Dockerfile, tests, lint rules, etc.

Turns out, it’s hard to maintain, especially when you have dependent repositories across. I.e. you have repository api that is using a package from another repository, let’s say commons. If you publish an update in commons, you need to go through all the dependent repositories and update commons there.

Now, just imagine how long it takes, to make a clone of each repository, make an update there and push changes back to remote. It’s hard to say for me, but these kinds of updates were leading to half a day work just for updating the changes in other repositories. Therefore, we allocated resources for changing that.

But, before I started migration to a mono repository, I spent some time investigating the pros and cons of other alternatives.

Recently, I’ve faced a problem with slow logs collection and their delivery to our logs aggregator — Graylog. So, I looked into fluentd documentation and digging up its sources to understand, how fluentd collects logs and how it delivers them.

It’s not an article in a regular sense; it’s more of a small tip…

Turns out that Node.js cannot receive signals and handle them appropriately (if it runs as PID 1). By signals, I mean kernel signals like SIGTERM, SIGINT, etc.

The following code wouldn’t work at all if you run Node.js as PID 1:

process.on('SIGTERM', function onSigterm() {
  // do the cleaning job, but it wouldn't
  process.exit(0);
});

As a result, you will get a zombie process that will be terminated forcefully via SIGKILL signal, meaning that your “clean up” code will not be called at all.

So what, you might say. I’ll describe a real case.

How often do you face the issue with configuring your development environment? How often do you configure your terminal? Did you install Command Line Tools? What about Homebrew, don’t you forget to install it? Maybe you forgot about some cool plugin for your shell and can’t find it?

This is the problem I am usually faced with clean MacOS install, so maybe you too.

Some error in the terminal, oh, I forgot to install X…
How did that work before? Oh, I had plugin Y, but I don’t remember its name…
Who enjoys remembering all the fishy commands? I don’t…
Burn out my own eyes with a default theme and colors? No, thanks…
Navigating through a plugin repository of your shell to find out all plugins you had
again? Haha, nope…
