Pawel Kozlowski @pkozlowski.bsky.social · 18/01/2026After using AI (chats / coding) for a while I would really like to invest into startups seriously working on the brain <-> computer interface. The distance between a thought and a result is still too wide. Typing and reading are now substential bottleneck for some of the work I'm doing. 020
Pawel Kozlowski @pkozlowski.bsky.social · 17/01/2026Iterating on a "visiting card" with Gemini (changed the place recently so lots of friends / contractors / etc that need my new address). Kind of insane what you can do in very few steps... I like this last concept - going with it unless you all think is terrible or ... have better ideas! 010
Pawel Kozlowski @pkozlowski.bsky.social · 13/01/2026Seeing technical presentations full of AI-generated images bring back memories of the days where we all were going giphy. Eh, good old times... 120

Pawel Kozlowski @pkozlowski.bsky.social · 07/11/2025Spent the last 4 months looking into LLM codegen quality and techniques of improving it for the new APIs (not in the training set). Many learnings from the process, with the key one being: LLMs "preffer" good API design. Codegen fails? Your human devs would be likelly confused as well! 151
Pawel Kozlowski @pkozlowski.bsky.social · 21/09/2025Time to go back home after two weeks of travel and speaking about @angular.dev . Thnx for having me @angularconnect.com and WhatTheStack conference! Got a couple more talks lined up this year but that's a story for another post. 080
Pawel Kozlowski @pkozlowski.bsky.social · 18/09/2025I'm so happy that @trueadm.dev shares his learnings in the open. There are 2 problems very close to my hart being explored here: - reactivity / rendering dance; - modern authoring format. Some will claim that UI fwks are "solved problem". I don't agree. There is still so much room for improvement! 0161
Pawel Kozlowski @pkozlowski.bsky.social · 18/09/2025Putting finishing touches on my "Angular: framework of the future" talk (wts.sh/sessions/8iw...) for @what_the_stack conference. Arriving a few days earlier to explore Skopje was a great move - loving it here! 171
Pawel Kozlowski @pkozlowski.bsky.social · 15/09/2025Tune to this one if you've got a chance. We will be sharing some LLM-related tools and techniques that I'm particularly interested in atm. 010
Pawel Kozlowski @pkozlowski.bsky.social · 15/09/2025We did lots of experiments with LLMs generating @angular.dev code. They are _great_. Totally should be part of the #Angular community, proudly wearing a #Angular T-shirt. 173
Pawel Kozlowski @pkozlowski.bsky.social · 10/09/2025LLMs are _really_ good at writing code - not a news at this point. What I find more interesting is LLMs used as beta-testers for new APIs and DSL: - start with idea + docs + examples - LLM-generate lots of code - see what and how it fails. It seems like LLMs tend to fail _similarly_ to humans 1/2 173
Pawel Kozlowski @pkozlowski.bsky.social · 23/08/2025I've got so many great memories from the previous editions of #AngularConnect and couldn't be happier to see it happening again. The hardest part of it all: select keynote material. With so much stuff happening in #Angular we will need to do some ruthless "scope cuts" - a good pb to have I guess? 070
Pawel Kozlowski @pkozlowski.bsky.social · 21/08/2025Yep, the Chrome DevTools Perf panel extension point is _great_. We clearly saw its potential and this is why @angular.dev ships with the tight integration.

Pawel Kozlowski @pkozlowski.bsky.social · 27/01/2025I wish this would be a more universal knowledge. I've profiled hundreds of apps. None of them was anywhere close to the tech limits. Perf of all was improved by relatively simple treatment of removing obvious bottlenecks. Most of those apps were never profiled until someone complained.... 2102
Pawel Kozlowski @pkozlowski.bsky.social · 24/01/2025There is so much passion, energy and history behind @angular.dev. There are many ways to tell its story and different people will have different stories. But I can very much identify with the story told in the Angular documentary: www.youtube.com/watch?v=nONH...

Pawel Kozlowski @pkozlowski.bsky.social · 25/11/2024Working on frameworks (and dev tooling in general) is such and interesting and subtle game. If we don't built-in enough abstractions / flex points people won't be able to do their job. But too much flexibility can make the tool cumbersome to use for _typical_ situations. 1/3 2357

Pawel Kozlowski @pkozlowski.bsky.social · 17/11/2024All modern JS frameworks run on the same idea: model driven UI (data is the source of truth) + declarative model to the UI mapping ("templates"). Simple, powerful and consequential. But I like pushing those simple stories to the "extreme" and "see what breaks". There are 2 places with cracks. 1/3 1190
Pawel Kozlowski @pkozlowski.bsky.social · 11/11/2024Angular v19 ships with the two new reactive APIs: linkedSignal and resource. On the surface those might seem like unrelated APIs. The truth is that both come from the same line of thinking: derive state without effects. Both linkedSignal and resource can be seen as specialized "computed". 1406
Pawel Kozlowski @pkozlowski.bsky.social · 10/11/2024Many of the design decisions in Angular have a very simple "backing story". One or two fundamental thoughts. But somehow those cornerstone thoughts are lost, or simply untold, when foundational ideas are translated into APIs and make into a release. 🧵 140

Pawel Kozlowski @pkozlowski.bsky.social · 09/11/2024Tool preferences is something that was on my mind quite a bit lately. Some heated A vs. B tech debates are really about tools philosophy. Ex.: small, focused and composable vs. do it all / integrated. It is not like is "better" than the other. All depends on the current needs. And ones preferences 070
