Thoughtworks have published their usual TechRadar. You can also get the full PDF report there there.

This tech radar provides some valuable insights into the industry. Besides, this is already the 31st volume, so you can compare it with previous versions. Just keep in mind that this tech radar (as any other) is biased, because it basically represents the Thoughtworks' customer base, thus it's not universal.

A nice overview of the evolution of Bluesky by Gergely Orosz and Elin Nilsson.

Bluesky is a decentralized social network which was born as an alternative to Twitter. It’s super interesting that for almost half a year Bluesky only had 2 engineers and even today the team behind the whole platform is rather small.

It’s also interesting that infrastructure wise they have started with AWS and Pulumi and eventually moved to their own equipment for cost savings.

A critical view point on OpenTelemetry implementation from VictoriaMetrics.

In nutshell, the idea is good, but the implementation is too bloated, which often happens when the aim is to provide a one-size-fits-all solution.

As a commenter pointed out in a Reddit discussion:

 problem is they are right, otel is a simple idea standardize observability. However when you get every vendor involved it can expand to a huge project very quick.

AWS at last allowed users to serve assets from private networks via CloudFront.

https://aws.amazon.com/about-aws/whats-new/2024/11/amazon-cloudfront-vpc-origins/

In the announcement, they mention simplification of operations and security, but not cost, and you have to pay for public traffic in AWS. So, not sure, what are the hidden costs of this new feature.

Another interesting article from our chat.

As you probably already know, Terraform has introduced ephemeral values in version 1.10. The goal is to address the long-standing issue with credentials in the state file.

However, there is also a great complimentary article by a HashiCorp developer, who worked on this feature, with the detailed justification. Honestly, this article is a good read!

​​For today’s Donations Monday I would like to remind you of a standing jar of my German teacher.

https://send.monobank.ua/jar/8jQSHW57kP

He’s also a volunteer and he uses this jar to address ongoing requests from the combatants.

These things may not be as favorable to the media compared to some other equipment, but it doesn’t make it not important.

And to re:Invent announces:

AWS accidentally reinvented a few things once again like "K8s administrator not needed anymore" and "DBA not needed anymore" which means that these folks will have a wonderful opportunity to automate some toil work 🥳

If you haven't checked out yet Top announcements of AWS re:Invent 2024, they are pretty decent

Regardless my feelings about Python, it's still a very popular language among the platform people.

So, here is a bundle of Python books by Pearson that I forgot to share with you earlier!

This offer is still valid for 7 days. As usual, you can pay about €25 to unlock the whole bundle.

One of the members of our community wrote an article about ArgoCD, more specifically about generators in an ApplicationSet.

This article has words "Part I" in it, so I hope that other parts are ready as well, since there is a golden rule: do not publish parts unless you have all of them ready :D

#cicd #argocd

I didn't pay enough attention yesterday, so I didn't post the second part of the article about Argo CD :\

Let's fix it! Here it is. This second part focuses on the .source configuration parameter of ApplicationSet.

Asking questions during an interview is as important as answering them, one could argue.

Here are a couple of articles with examples of what to ask your potential employer and the team.

- Reverse Interviewing Your Future Manager and Team - an old article from Gergely Orosz on the topic. Kudos to him for not closing old articles behind a paywall as many Substack creators do!
- 40+ questions to ask at a job interview - the website itself is Berlin-centric, but these questions are independent from a location.

Also, one of the top motivations to search for a new job is compensation. So, if you have spare 10 minutes this Sunday afternoon, folks from DOU would greatly appreciate if, if you could participate in their annual salary survey (in Ukrainian). This year they collect all the answers, including people who do not live in Ukraine (hopefully, those answers won’t be filtered out in the end results as well).

For today's Donations Monday, we’re raising funds to support a friend of my wife, who is currently serving with the KORD Special Purpose Police Unit on the front lines in Donetsk.

His team is in urgent need of essential components for
the FPV drones.

The funds are for:

- Repeaters for better signal range
- Antennas for stable communication
- Batteries for extended flight time

Your support will help KORD improve their operations and stay safe while protecting Ukraine.

An online calculator for DataDog costs + some tips on how to keep these costs in check.

Yes, this is a marketing material, so you need to take the "comparison" part with a kilogram of salt. Also, the calculator itself is tricky: DataDog has many ways of "committing" to some capacity, which impacts the price drastically. They mention this fact in the article as well. So, this calculator is rather a reference than a precise tool.

Otherwise, this article provides some sane tips on the DataDog cost management.

Breaking down OpenAI's outage: How to avoid a hidden DNS dependency in Kubernetes - in this article, folks at Render analyze the recent OpenAI outage and provide some insights on the possible cause of the issue.

This article also serves as a reminder that you'd better run DNS and the Control Plane on separate nodes and also that the data in ETCD is organized by namespace, thus listing "all" resources is very costly, especially in large clusters, since you need to scan everything.

For today’s Donations Monday, I want to share with you a fundraiser from one of our community members.

This is a fundraiser for a mini-excavator for the 36th separate brigade of AFU, which will tremendously help them to dig trenches in winter.

An almost New Year episode of our voice chat (in Ukrainian).

At the end of this year, we gathered to discuss certifications: who needs them and why, and how to obtain them. You can find the episode on:

- YouTube
- Substack
- Spotify
- Apple Podcasts

Enjoy this new episode while making some New Year salads!

P.S. Please, let me know in the YouTube comments or elsewhere, if you like the voice chat format and if it makes sense to continue it in the new year. Cheers!

З новим роком, коти! ❤️

​​It’s time to get out from the holidays hibernation and get back to this channel again. And what could be the best way to start a year, if not with a donation for AFU?

Wife of my friend from my very first tech-related job raises 15k UAH for AFU. There’s also a raffle to win a certificate to buy books.

The goal is not that high, so I’m pretty sure we can close it today together!
