This year, the focus of the conference is security.

We'll discuss context-based security, cloud hacking scenarios, information security in the cloud, defense against cyberattacks and the complexities of cyber warfare, vulnerability management implementation with AWS services, OWASP Top Web Application Security Risks, and more.

Just to name a few speakers: Nazar Tymoshyk — CERT-UA State Communications Engineer, Anastasiia Voitova — Head of Security Engineering at Cossack Labs, Brian Tarbox — Principal Solutions Architect at Caylent, Rotem Refael — Director of Engineering and open-source ARMO, and many more!

See you there!

A nice read about ArgoCD.

What I especially liked about it is that it goes beyond your typical “hello world” examples and also touches topics like multi cluster deploys, app-of-apps pattern, and encryption.

A case study from Grammarly on their migration from Graphite to VictoriaMetrics, which helped them to improve DevEx as well as save money.

Unfortunately, there are not many technical details in this article, but I still want to share it, ‘coz I’ve rarely seen posts about VictoriaMetrics in production. So, maybe you are the one who can write something on the matter?

P.S. Do you, folks, even remember Graphite?

Bees With Machine Guns is a tool to load test web applications.

The main difference from other popular tools like Vegeta is that in this case instead of using a single CLI, the tool creates a "swarm" of micro instances in AWS to emulate a DDoS attack so the load originates from multiple points, not a single one.

​​For those of you who like meddling with their terminal emulators - Oh My Posh is a command line prompt that can replace p10k, since the latter one is no longer actively maintained.

Here’s a video where it’s shown in action (and basically this is how I discovered it):

https://youtu.be/9U8LCjuQzdc?si=ho-67Xuht02Ql0kT

What I personally liked from the video is a possibility of creating a neat config in YAML or TOML and ease of replacing current config with another one right in the shell configuration file.

I’ll definitely give it a try when I have some time.

A new late issue of the CatOps Newsletter is out!

https://newsletter.catops.dev/p/catops-digest-2024-06-09

I'll try to get back to the bi-weekly schedule with newsletters coming on Sundays, but no promises for the Summer.

There are some articles-cheat sheets that are very useful in certain circumstances.

For example, here's a nice cheat sheet for reassignment of Kafka partitions. As you may know, Kafka doesn't reassign partitions automatically when new brokers are added or removed from a cluster.

Save this one just in case, especially if you have Kafka somewhere.

For today's Donations Monday, I would like to share with you a fundraiser by Come Back Alive and PrivatBank for the establishment of the "Yatagan" UAV school.

The goal is to raise 33M UAH and currently about 21.5M are raised. It's also possible to donate using a European bank card - I've just checked that ;)

​​As Charity Majors put it: "Nines do not matter if your users are unhappy". At the same time, nines do not matter if your users do not care.

This small article is a friendly reminder about the cost of adding nines to your SLOs.

P.S. There are some other interesting articles in that blog, BTW.

An article called Maybe you need Kubernetes is surprisingly not about Kubernetes.

Instead, it touches the topic of embracing the complexity of modern tech and, more importantly, how one can only progress by learning complex stuff.

As the author puts it himself:

People don’t like to hear this, but difficulty is a moat. When something gets easy, it gets cheap. If you want to be paid a lot, you need to be really good at something that’s both in-demand and hard. If it were easy, everyone would be doing it.


P.S. It's also nice to see that this article is an answer to a video on YouTube. I missed the good old polemics. It seems like online comments have killed it.
