KiND is a popular tool for local development in Kubernetes. But what if the thing you're developing is not published anywhere yet?

Sure, you can use tools like Tilt or Skaffold, but they add additional knowledge overhead.

However, you can also load a Docker image into a KiND node. Of course, this won't be such a streamline developer experience as with the tools mentioned above, but it will make the job done with very little additional configuration.

If you work with NodeJS on backend, this article may be useful to you.

This one is about how to increase (or decrease) memory limit for NodeJS when working with PM2.

In his last interview for Deutsche Welle, Taras Chmut - the head of Come Back Alive foundation - described that it's much harder to raise funds for projects that are focused on trainings and other strategic initiatives that may not result in the "direct hits" on the battlefield.

That's why today I'd like to share a fundraiser for the Captain's Trainig program by Come Back Alive.

25 years of Google data-center networking evolution is a sneak peek into Google's internal network, phases of its evolution through the company's history, as well as technologies that allow them to handle up to 13 Petabits/sec of bisectional bandwidth.

I especially liked this quote:

 network is the foundation of reliability for all other compute services, from storage to AI. As such, the network must fail last and fail least.

A brief overview of how to choose the right size for your RDS instance in AWS.

Although, I would argue that certain workloads would already experience problems at 80%+ CPU load on CPU. So, sometimes it doesn't make sense to wait the whole four-week evaluation period.

Also, make sure to keep track of your reserved instances: you don't want to pay more than you should when jumping between instance types!

You have a Database that can be affected by Disk corruption, and you have millions of transactions? Well, good for you that nothing bad happens yet.

But what if I say that there is better solution, x1000 faster and safer? Just send 0.1BTC called TigerBeettle.

Also, it has of the best presentation what I ever saw. Check it

A new fundraiser for the International Legion, where my friend's brother serves.

This is a fundraiser for ongoing expenses such as car repairs and Starlink fees. The goal is 80k UAH and about a half is achieved already.

An article and a CNCF NA talk about Atlas - a tool to manage database migrations, and specifically about the Atlas Operator - a way of managing database state in Kubernetes. It's important to point out, that the database itself doesn't have to reside in Kubernetes.

Except some advertisement for Atlas, this article actually points out problems of executing migrations that are not limited to K8s. Still, even though this is an article about a tool from a creator of the tool, I think both blogpost and the tool itself are interesting.

But to be completely fair, there's also the SchemaHero tool - a truly open source one.

Where you good at math in school?

Humble Bundle sales a collection of Math for Programmers books. One of the books is from the “Grokking” series. I’ve heard that series is a good one.

Also, one of the books is written by a Ukrainian author. You can read an interview with him on DOU (in Ukrainian).

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.
