   A colleague of mine wrote an article about data migrations. Handling data migrations without anyone noticing. This one specifically is about a data migration that took several days and involved some external systems. Hopefully, these learnings will help you to design similar migrations at your place! #data #programming

   I’m going on a vacation, which means that I likely won’t post at all or post something very occasionally for the next 2 weeks. Here are 2 AI-related book bundles on Humble Bundle, so I don’t just leave an informational message here. - AI in Production by Manning - only 4 days left. - GenAI and Agentic AI by BPB - 20 days left. See you in the end of October!

   While I’m still enjoying my vacation, this CVE is too interesting to pass by. PwnEscape: Guest-to-Host KVM Escape (CVE-2026-99999). First of all, it has a neat number, but it is also has 9.3 severity score. This CVE describes how the IPv4 checksum check mechanism in Linux can be used to gain access to the host machine from a sandbox or a virtual machine. The former article explains how this CVE was identified. And yes, it was found with help of AI, and apparently it dates back to the 2.x ker…

   For today’s Donations Monday, I’d like to highlight a fundraiser for 3 laptops for the Air Defense unit (1st Corps of Azov). Strictly saying, that's a way to have heat, light, and gas, not only inside ourself, but in our houses too. So, please don't hesitate to donate: https://send.monobank.ua/jar/4Xqw8mdW2W #donations #Ukraine

    Here's a story from a colleague of mine about RDS connection pooling and our endeavors with it. Connection pooling. A long journey.. The main takeaway is that the RDS Proxy is nice and managed, but not a silver bullet suitable for all the cases. Similarly, pgbouncer is old and boring, but it gets the job done. #aws #rds #databases

    ​​I traded my personal information for a report again, so you don't have to. This time it's "The State of Developer Experience 2026" report by Atlassian. I haven't read it fully yet - it is 24 pages long, and honestly I usually just skim through such reports. Still, here are some bullet points from the report's executive summary organized by me with some personal comments in italic: - People still report productivity gains from AI, albeit less dramatic. There were previous reports that people…

    I have quite a few articles piled up in the “to read” queue for the time I was on vacation. So, I was not sure where to start and decided to read an article about reading. Going a bit meta, sorta speaking. Here it is: You Are What You Read by Steve Huynh. This is a complementary article for another piece of his, but unfortunately that other article is now behind a paywall. I am also not sure if he wouldn't paywall this one as well. However, if you're subscribed, you can still find both articles…

    Terraform drift has always been PITA. Now, you have a ready-to-use GitHub Action to run tfdrift CLI to get your reports. Terraform Drift Is Now a Native GitHub Security Alert is an article that explains how. P.S. This article comes from Anton Babenko's weekly.tf newsletter. It's a great resource about Terraform, so make sure that you're subscribed if you're interested in Terraform. #terraform #tofu #cicd

    ​​Adding some video content to the mix, which is, I think, suitable for a weekend. Here’s a talk from Gergely Orosz aka The Pragmatic Engineer on the trends in the industry from as conference in NY this September. https://youtu.be/Ru99FGJ_yuE?is=zYJrIOYbe8gsSQhp I usually do not read comments to YouTube videos, but some comments here are interesting. Some of those repeat the same takes, but paint those in different colors, which adds the perspective to the whole ordeal. #slides #ai

    I think it was Stafford Beer who raised concerns about new cybernetics and AI developments being applied in the "old ways" and thus missing their potential. "Hammering nails with a microscope" sort of things. In his article "The Agentic Software Factory is the Wrong Metaphor" Rob West makes a similar argument about the new trend of AI-powered "software factories". This is not an anti-AI piece. Quite the contrary: it argues that the true value of software development lies in understanding the do…

    ​​My colleague from the previous job wrote an article about him fixing a bottleneck in ArgoCD (bug is in version 3.4, fix is in 3.5). "When a Routine Argo CD Upgrade Slowed Everything Down" would be interesting not only as an investigation story, but also as a cautionary tale for those, who write Kubernetes controllers. The gist is that a Kubernetes API call on a hot path may be difficult to catch in the smoke tests but can easily become a bottleneck when reconciling many resources. Yet, you m…

    Lately, a bunch of websites ask me to create a passkey. "Passkeys are a trap. Do not use them." is a nice technical primer on what passkeys actually are. Also, you are adults; it's not my job to tell you what to use and what not. I'm just sharing articles that I find interesting here. UPD: the issue with passkeys is the remote attestation i.e. a server can dictate the client what passkeys are acceptable and what passkeys are not. This is a tl;dr for more details read the article. #security
