Digest 01/2026

I have 100+ tabs open in my mobile browser all the time. I use it as read list eg. whenever I see something interesting which I don't have time to read at that moment, I just open it as new tab and leave as is. Once in a time I get so frustrated by the sheer quantity of the tabs that I want to just want to close my eyes and hit "Close all" button.

Then I remember that this habit of mine once served a real purpose - I've been hoarding articles for the company's newsletter. And then suddenly I don't want to close those but I want to pick few and send them to someone who might find it interesting to read it.

Security & AI

Now this looks like an good old whack-a-mole game to me - threats generated at rapid speed by AI tools also caught at rapid speed by AI tools.

📺 There is new type of security attacks emerged from vibe-coding.

📺 Here is great video on how almost whole Internet was pwned.

Writing the code was never hard - once you learn how to code it is easier and easier. The hard part is to think about problem and come up with the solution. AI only solved the easy part.

Other

📺 If you are tired of reading watch this take on System design from Bassem Dghaidi, senior software engiheer at GitHub. Basically you will find out that building simple things is actually hard. Design for now not for what could happen in 10 years.

Interesting projects

• formisch - schema-based headless form library from Fabian Hiller - creator of valibot
• fate - interesting data client for React and tRPC
• TypeGPU - control WebGPU APIs with TypeScript
