The International AI Safety Report is the world’s first comprehensive synthesis of current literature of the risks and capabilities of advanced AI systems. Chaired by Turing-award winning computer scientist, Yoshua Bengio, it is the culmination of work by 100 AI experts to advance a shared international understanding of the risks of advanced Artificial Intelligence (AI).

From one conference to another!

On 22nd of February (which is sooner than it may appear) I’m speaking at the DevOps fwdays’25 about the pitfalls of a platform team and caveats you can encounter when building one. The talk is online and in English, so you can join from anywhere you want!

Also, here’s a promo code for 15% off from your ticket: 4A91C4612C

Another thing from FOSDEM PostgreSQL devroom is pgroll - a tool that allows one to execute zero-downtime (zero lock-time really) migrations in PostgreSQL.

Slides are available at the talk page. I hope, the video will be available soon as well. It was a very good talk!

Ok. I think I can start sharing things from FOSDEM / CfgMgmt Camp conferences.

To my knowledge, the videos are not available yet, but here are some pretty self-explanatory slides from the opening talk of the PostgreSQL panel: PostgreSQL Performance - 20 years of improvements.

In this talk, the author - a core contributor of PostgreSQL - presets the benchmark results of 10 major versions of PostgreSQL, so you can see how it evolved over the years.

​​There’s a new fundraiser by Come Back Alive has a new fundraiser for communication equipment for the army aviation.

As someone who studied telecommunications back in a day, I have a soft spot in my heart for everything related, even though I don’t remember shit about telecommunications.

P.S. Unfortunately, smaller fundraisers do not get much traction any more. Hopefully, a bigger fundraiser will go better.

If you missed O’Reilly’s “Linux for seasoned admins” books bundle, you can get the same books in a new bundle that is now called “Linux from beginner to professional”.

There are some good books in that bundle, BTW.

A small list from HoneyComb with good practices to organize your logs.

It's in a form of a numbered list (the peak Internet format, he-he), so it is easy to read. If you're a seasoned engineer, there won't be any unexpected points for you. However, from my experience, log management is often left as an afterthought. So, maybe, this article could serve as a neat checklist for you.

There are many different release patterns. Today I'd like to share with you one that is called "dark reads". This one is hard to google, because you get a lot of articles either about dark patterns of web development or a bunch of photos of dark red wallpapers.

Here's one article I could find about it. The core idea is that you have both versions v1 and v2 running at the same time, but you only read and outputs from v2 and check that for correctness.

It is very similar to canary releases or feature flags, but it's more applicable to data pipelines. If you have a stream of messages, it's not always easy to stream a percentage of them via a new system. Also, when running two versions at the same time, you need to have additional logic to deduplicate messages at some point. "Dark reads" says that you should be able to validate and discard v2 events on the consumer side and flip the switch once you're satisfied with the results.

How AI-assisted coding will change software engineering: hard truths is a sort of "wrapped article". You can call it a "reaction article" or an "enriched article" if you with.

It has two parts: the original post about AI usage in development teams by Addy Osmani, I think I already shared this article on this channel.

The second part are comments by Gergely Orosz - the author of Pragmatic Engineer - on the topic.

I think, those comments are valuable and do provide additional input and perspective instead of just parasitizing on existing content, as many reaction videos do.

So, enjoy! Especially, if you haven't read the first article.

One of the strengths of Go is the existence of default helper tools such as gofmt and goimport. Thus, you don't have to worry about formatting, for example. These tools can also be easily integrated into your editor of choice.

For quite some time now, I have to write Python code in professional setting and an automated import is one of the things I miss the most. There are tools to achieve that, ofc, but still.

Another thing about such helper tools is that we often take them for granted, especially when they are default. But you don't have to!

This article describes on a high level how goimport works. While it is kinda intuitive, it's always nice to see a bit deeper perspective. And if you want to dive even deeper, you can always just read the code yourself.

I know that oftentimes folks are critical towards Packt, because many books and courses there are not that good. However, some of them could still provide value.

Thus, it's nice to get them at a discount. Right now, Humble Bundle has two discounts on Packt products:
- Books bundle about databases
- Courses for AWS certification

I might actually get the one on databases, because I want to learn more about Postgresql, but I don't have any specific resource in mind except reading the docs.

Speaking of certifications, we had a voice chat recently on that topic. The voice chat is in Ukrainian.

It seems like this week is a week of cultural posts, so be it.

This one is as cultured as it gets, since it explores a technic of Socratic questioning towards the idea that meetings are the waste of time.

You can try it in your team, if you like. Maybe, you'll be able to remove some meetings or re-arrange them in a better way. Or maybe, you really need more meetings, not less - who knows.

It is this time of the year: many companies are doing their performance reviews and calibrations. So, make sure to recall what you did last year, write something nice about your peers. Keep calm and carry on.

Here is a nice small write-up on performance reviews, specifically its dark side. One thing to take away from there:

> If you want them to MAYBE change, talk to them directly. If you want them to get stabbed by management, put it in their performance review.

Here's also an opinion piece from Rory Sutherland - a vice chairman of the Ogilvy & Mather group - where he explains how individual performance goals jeopardizes risk taking with potential sharable results.

P.S. Another interesting topics when talking about performance reviews in the way they are today is the use of AI. I know for sure that people use it to write those reviews, and it can be definitely used to analyze a huge influx of reviews. Thus, we are one step closer to a singularity in which machines will write reports for other machines to read, so us, flesh bags, can focus on our work.

An article on how to foster a culture of ownership in your company. Ownership culture is crucial for engineering success.

Yet, I have a problem with such articles: they are always written from the perspective of a senior manager or a high-level individual contributor. In this case, the author describes the time he was a Principal Engineer.

I am yet to see such an article from an individual contributor's perspective. At this point, I am not even sure, if it's possible to make grassroot changes in your organization, given that the organization is big enough. If you have a success story, please, let me know!

P.S. This particular Substack also have a clutter problem: there is a sponsor part in the beginning and a self-promotion part in the end, which you can skip.

​​For today's Donations Monday, I would like to remind you about a fundraiser 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
their FPV (First-Person View) drones, which are critical for
surveillance and reconnaissance in the region.

The funds will go towards purchasing:

- 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.
