Just recently Denys made a video about the interviewing process into a “hot” AI startup.

They use Python there (surprise, surprise). And just today I’ve noticed a Python book bundle on Humble Bundle.

Also, if you’d rather switch to the management career track all together, there’s another book bundle for you.

I know that some people complain about the quality of Packt books, but I’m a simple man: I see a relevant book bundle - I share it. Now, you can decide for yourself.

You know how it works: people are posting their end-of-the-year results at the end of each year and their predictions for the future at the beginning of each year.

In this video, Viktor Farcic shares his thoughts on the tools to check out (or continue using) in 2024.

​​Good news in Terraform world!

tofu test syntax is the same (or pretty similar) to terraform test syntax in 1.6+

Also, it's first GA release of opentofu (about 5 months from forking)
Let's see how it will go. Currently, I can said that there bunch of folks who bombard everything with "please support tofu in N" (before there were any releases) but don't do anything to contribute to projects.

Also, in case you're excited about migration to tofu - firstly, you must fix all your TF code stacks, which is nearly impossible in huge organizations. Or make gradual migration => live with both tf and tofu side by side for months.

Infrastructure as Code and Configuration Management topics are old and boring. It seems like it's almost impossible to have anything conceptually new in this domain, except some drama around licensing.

Yet, in this blogpost Nathan Peck (he works in AWS, IIRC) argues that we could do it differently and that we could do it better.

The core idea is that instead of writing some YAML or DSL to define various resources and then try to group them somehow, we could leverage the same approach that Web technologies took. More specifically, "decorating" objects with properties provided separately. Similarly to what CSS does to HTML.

There's also a discussion of this post on Hacker News

We usually don't post event announcements. Yet, there's an exception: our direct involvement in the event :)

On 17th of February I'm speaking at DevOps fwdays'24 conference together with other wonderful people.

You can join the conference either offline in Kyiv or online from anywhere in the World as long as you have the Internet connection.

Also, I have a promo-code CCD4090099 that gives 15% off for any type of tickets!

UPD: if you would like to talk at the conference, you have the last chance to submit your talk via the CfP form!

Google shares their experience from 20 years of SRE.

This article contains overview and lessons learned from some older incidents. It’s nice, but I can’t say that there is any mind blowing information in there. Anyway, it’s nice that it came from Google.

A late Sunday digest is out!

​​My boss from one of my previous jobs used to say: “Stop starting, start finishing”.

TBH, I wish much more companies adopt this motto. So, let’s lead by example!

A joint fundraiser by Come Back Alive and Kyivstar - “We live here” is almost over! Its goal is to raise 175M UAH and right now they are lacking about 4M UAH to close this goal!

So, let’s help them to finish it!

For some folks it’s easier to digest information in video format.

I am myself guilty of watching way too many YouTube videos.

Thus, today I want to share with you a bundle of Linux Video Courses from Packt & HumbleBundle.

#books #bundle

We don't make posts related to events, unless we are personally invested in those.

Today is one of such examples. I am a part of an organizational committee of the first DOU Technical Conference.

The CfP is still open. However, it's closing tomorrow.

So, don't miss your chance to become a speaker!

The only caveat is that this is an offline event, so you should be able to physically travel to Kyiv on the day of event.

Do you run databases in Kubernetes?

Even if you don't, I bet you may run database migrations there. How do you do that?

This article on "The New Stack" makes a case for GitOps approach to the database migrations in Kubernetes.

*tl;dr*: It's Atlas Operator, there's no alternative.

There were quite a few nice bundles at HumbleBundle lately!

This one is about cloud as well as ML pipelines design, which should be interesting.

Also, these are O’Reilly books and O’Reilly is famous for their high quality.

How Discord Serves 15-Million Users on One Server.

I think this article was posted before on some of DevOps-related channels.

tl;dr: It's BEAM & Elixir. Also, every time you see an article noscriptd "how a chat app scales to crazy number of users", it's always BEAM.

Yet, in their case, Discord had to make some performance analysis and architectural optimizations with some data offloading. That part is interesting.

P.S. I'd love to learn Elixir someday, but I have zero experience with it or Erlang, or FP in general. So, if you're in the same position, and you're looking for a learning buddy, please, let me know :)

#elixir #architecture

And now it's time for a story of how Pinterest scaled to 11 million users with only 6 engineers.

No BEAM this time, though Pinterest isn't a chat app either. They managed to scale that much and stay so lean thanks to the architectural decisions (mostly around keeping it simple).

P.S. Also, Pinterest is probably the best social network out there (if you could call it a social network).

#architecture

I’m a CLI guy. For me it was always easier to use good old commands like find and cd to navigate around. At some point I even memorized the flags of tar.

Thus, it is still much easier to me to use plain kubectl with a couple of plugins to navigate the clusters.

However, I know that many folks prefer graphical interfaces or at least some TUI. Also, I remember that a lot of folks were pissed when Lens split into a community and a paid versions.

So, today I want to share a new native Kubernetes desktop client - Seabird.

I haven’t tried it for the reasons I mentioned above, but you may enjoy it.

​​Today a new issue of CatOps Newsletter should’ve come out. However, it’s delayed for reasons.

P.S. If you’re attending Fosdem/CfgMgmt Camp, let’s meet for coffee!
