warpech··on SpaceX to buy Cursor for $60B
Yes, it seemed from another word at the time. Now is table stakes. Thanks for showing the way!
warpech··on HTML is a native image format, hear me out
What wrong with inlining base64 in regular .html if you want it all in one file?

Plus zipping that one file is you insist on a smaller file size

warpech··on Show HN: Open-source Workspace (mail,docs,spreadsheet,drive) web/iOS
Thanks for a good word! Founder of HyperFormula here. HF will go AGPL soon, too
warpech··on Bun support is now limited and deprecated
I see Bun’s Rust rewrite (esp the style how it was done) as a form of massive internet trolling for PR reasons. By making a bigger fuss about it, we’re feeding the troll
warpech··on Turbo Vision 2.0 – a modern port
My programming career literally started in a dumpster in the ’90s, when I found a Turbo Vision book someone had thrown away. I picked it up and immediately fell in love with the bluish TUIs that anyone could make.
warpech··on Ask HN: Any interesting niche hobbies?
I got into improv theatre. There are groups in every city, at least here in the EU. It is both fun and developing creativity, alertness, etc.
warpech··on Lightpanda migrate DOM implementation to Zig
Thanks! But I meant JS based virtual scrolling in web pages. E.g. dynamic data tables that only render the part of the table that fits in the viewport.

> Definitely fun for me to watch as someone who is making a lightweight browser engine with a different set of trade-offs (net+DOM+style/layout/paint-only with no script)

Both projects (Lightpanda, DioxusLabs/blitz) sound very interesting to me. What do you think about rendering patterns that require both script+layout for rendering, e.g. virtual scrolling of large tables?

What would be a good pattern to make virtual scrolling work with Lightpanda or Blitz?

warpech··on Show HN: Picknplace.js, an alternative to drag-and-drop
I love this. We need more experimenting with UX status quo. Especially with drag and drop, which, I think all many would agree, is one of the not ideal UX patterns espacialy with scrolling involved.

The research is never over. Good ideas, bad ideas, doesn't matter as long as they continue to inspire.

warpech··on Ask HN: What are you working on? (July 2025)
As a HyperFormula founder, thank you for the mention. I wonder what’s your opinion on our formula library
warpech··on Default styles for h1 elements are changing
What surprised me that they roll it out to 50% of the beta channel users. So you might or might not see the change until they roll it out for all
warpech··on We can, must, and will simulate nematode brains
Such a beautiful magazine design. Does anyone have recommendations for more skillfully designed online magazines, blogs, etc?
warpech··on A Commentary on the Sixth Edition of the Unix Operating System (1977)
I was very curious how come there is a PDF from 1977. Apparently it is built from these source files: http://www.lemis.com/grog/Documentation/Lions/index.php

A fork on GitHub: https://github.com/kanner/lions-book

warpech··on Is My Blue Your Blue?
Agree. If the author collects the IP address of the response, maybe countries can be mapped retrospectively.

Amazing news! It would be great to read how did it come to attract such great sponsorships. Was that actively searched for by Andreas?

warpech··on Engineering for Slow Internet
I assume it was considered, but I don’t see it mentioned: Would it be a terrible idea to use a cloud computer and Remote Desktop/VNC to it? Your slow internet only needs to stream the compressed pixels to your thin client.
warpech··on Ask HN: Why do you all think that Htmx is such a recent development?
Sure, the concept is not new at all, but it is distilled to a very usable form. A similar comment can be made about TailwindCSS.
warpech··on Rethinking Text Resizing on Web
You are right. I edited my comment to remove the negative sentiment towards the advice itself. I also admire the craftsmanship there. Still, the dark patterns are just increasingly unbearable. Same can be said about many market leaders in other categories.
warpech··on Rethinking Text Resizing on Web
I find the experience of Airbnb user hostile. The last time I checked, the app pushed irrelevant search results on me with no option of turning that off. Now they give advice on UX? The advice might be sound, but it comes from an authority in marketing, not UX

warpech··on How do computers calculate sine?
This made me realize that trigonometric functions are not deterministic across different CPU architectures, OS, and programming languages (floating point precision aside).

E.g. I would assume that Math.sin(x) returns the same thing in NodeJS on Windows and Mac/M1, but it turns out it is necessarily so. https://stackoverflow.com/questions/74074312/standard-math-f...

warpech··on JSR: The JavaScript Registry
I am not a user of Deno, but I acknowledged that HTTPS module imports were one of the original selling points of Deno compared to Node/NPM. Was it revised at some point that a package repository is needed? What's the back story?
warpech··on Ask HN: Making an organization focused on making modern and efficient apps
Setting "green" as a goal in a project, including software, might increase the possibility to get funding grants. YC "Requests for Startups" recently wrote about how much money there is for grabs in "climate tech": https://www.ycombinator.com/rfs
warpech··on Web design inspiration catalog
I have kind memories of Styleboost, TheFWA, K10K... I wish I also know PatternTap back then.
warpech··on How to Annotate Everything
I recommend everyone who's looking for a single solution to annotating common online media to check out Readwise Reader. It just went into public beta. It can annotate Web pages in original or in a beautiful reading mode, PDFs, YouTube, and probably more things that I haven't tried yet.
warpech··on GPT based tool that writes the commit message for you
Came here to make the same comment.

There is a great blog post about it: https://dev.to/jacobherrington/how-to-write-useful-commit-me...

It boils down to the following commit message template:

  <what you changed>

  because <why it was needed>
warpech··on What things did you purchase that enhanced the quality of your life in 2022?
Home office lighting.

In my home office room (10.5 m²/115 sq. ft), I used to have 4 neutral-white (3000K) LED bulbs of average brightness (450 lm).

I replaced them with the same number of cool-white (6000K), super bright LED bulbs (900 lm). What a difference! It took a few days to get used to it, but I am very happy with the change. I feel much more energized at work.

I sometimes work before bedtime, and I was worried that the lew light would affect my sleep quality, but I haven't noticed any difference in that respect.

A while ago, I read a blog claiming that most people have their light at home way too dim, but I cannot find it anymore. If anyone has some resources on this topic, I would be grateful for a link.

Edit: Fixed the color temperature values, added some bg info.
