For this Donations Monday, I want to share with you a well-known Serhiy Prytula Charity Foundation.

Kelsey Hightower said that he’s retiring from Google.

So, I would like to share with an episode of the ReadME podcast with Kelsey.

ReadME is a community podcast by GitHub. So, you may also find other interesting episodes there.

VictoriaMetrics have released their first iteration of the log platform!

Here’s the info:

The first release of VictoriaLogs!

Release page on GitHub

Documentation

Docker demos

Helm Chart

Here you can find a Benchmark for VictoriaLogs

Since I’m not a user, it’s hard for me to provide feedback right away. Yet, if you use it or want to try and want to provide any feedback to the maintainers, do not hesitate to submit bug reports and feature requests on GitHub.

A new episode of our voice chat chat (in Ukrainian)!

This time we spoke about job related topics beyond DevOps. Specifically:

- How often does it make sense to change a job. And what does “often” even mean in this context.
- Does it make sense to grow professionally beyond the Senior level or it can be the final stop in one’s career.

You can listen to this episode on:

- YouTube
- Substack
- Spotify
- Apple Podcasts
- Google Podcasts

BTW, since I moved the audio hosting to Substack, it makes sense to subscribe there to get new episodes right after they’re published.

A story from VS Code developers about how they made bracket pair colorization 10,000x faster.

I like such articles, which touch topics of raw computer science. I think such stories help us to reconnect with the beauty of our craft.

Although, it won't make me switch to VS Code from NeoVim :D

A system design exercise for on-premise infrastructure. The article is called DevOps Big Picture (On-Premises). However, it only explores a single example with a limited scope and a lot of assumptions. Yet, you still can use this diagram as a baseline in system design interviews, for example.

Unfortunately, data layer is completely missing there. I mean, data layer is the most difficult one, so a lot of people are omitting it on purpose. I cannot blame them for that. So, you can have a mental exercise and think about how would you manage the persistent data in the proposed infrastructure 😉

​​Git is simply too hard.

I have mixed feelings about this article. On one hand, Git is too hard indeed. I personally google certain Git operations from time to time.

On another hand, this article doesn't provide any alternatives or ideas on how to fix this situation. Also, a lot of Git complexity comes from its distributed nature. Distributed systems are much harder to architect compared to centralized ones. Although, currently, we're mostly using Git as a centralized system nowadays.

So, I'll just add this well-known comics here.

A new issue of the CatOps digest is available on Substack!

#newsletter #digest

UA Responders is a foundation that raises funds for tactical medicine, protective gear, and field hospitals.

And some drones, of course.

Handling concurrency is hard, even if it was made simple.

The Go 1.19 Atomic Wrappers and why to use them explores the sync/atomic package which was introduced in Go 1.19 and use cases for it.

I haven't used this one personally, but we have sync.Map in one of the projects to get the results from goroutines in one place.

Another article from our subscribers.

My experience migrating my infrastructure from Terraform to Pulumi is a story of the IaC migration to… well, Pulumi. A nice thing about this article is that it has some concrete examples of code as well as recommendations out of experience.

Yet, the final thoughts are somewhat questionable. For example, the claim that Pulumi is faster without any measurements.

BTW, I also wrote an article about Pulumi 3 years ago. It’s obviously outdated today but it’s interesting to observe how the project evolves.

P.S. If you want to share an article or just have a casual conversation, do not hesitate to join our chat (chat is in Ukrainian).

Wanna share a video with you about WTF is Platform Engineering.

https://youtu.be/ghzsBm8vOms

I would say it's good enough. Mostly because the reality is usually more complex than the theory. However, if you were wondering WTF is Platform Engineering, this is a good start!

(and no, platform engineer is a specialization, not profession!)

Today's Donations Monday request comes from our friends' channel - Ukrainian DevOps Digest.

They are raising funds for a retransmitter for the 28th brigade.

Here's the link to the Monobak jar: https://send.monobank.ua/jar/2cEiqdkjQ3

Pro-tip: if you copy the Monobank jar link into your mobile browser, you should be able to select Apple / Android Pay as a payment method and thus pay from a different card. It doesn't work all the time, but this is a nice workaround in case you don't have a Monobank or another Ukrainian card.

I personally don’t know this publisher. Yet, the noscripts of some books look interesting. For example, there is a book about FinOps as well as “Kubernetes for Jobseekers” (lol).

This is a Cloud OPS and Development bundle by BPB.

If you know this publisher or have any feedback on these books, feel free to share your impressions in our chat (chat is in Ukrainian).

As usual, you can pay different amount to unlock different number of books. This bundle is active for 20 more days.

It may happen that you have a catch-all repository to store some work that may or may not be important. Notice, it's not quite a monorepo pattern, rather a single junkrepo. Like, I saw devops, utils, tools, and similar repositories in quite a few companies.

But what if some things from those repos are actually important, and you want to have a dedicated home for those things? Here's a guide by GitHub that explains how to separate things from a repository while saving the Git history.

This guide is created by GitHub, but it should work with any Git repository. Although, I only tested it with GitHub.

Enjoy!

The episode is in Ukrainian and available on:
