I was in the US two weeks ago, looked everywhere for 1 module 32 gb ddr4 sodimm, couldn't find it anywhere. But apparently it was pretty expensive as well (from the price tag on the empty shelf in best buy)

I never liked React, but after working with it for several years, I got use to it. Specially JSX. Pretty neat to mix html and js in the same code. That actually inspired me to write tinyJS - https://github.com/victorqribeiro/tinyjs

Later I've a managed state, cause let's agree, it's pretty convenient to have UI updated after a change in the state.

That's very interesting, thanks.

The first time I went to the US I saw a foldable electric bike, in target, I think. Being someone who likes to explore the city (burning calories) I thought to myself: I can cover a way bigger area by bike than by foot. I can carry this with me to my travels and goodbye Uber. Thankfully I called United before buying it to ask If would be able to bring it home with me. The answer was no, of course. No eletric vehicles of any kind on a plane. What a shame.

Should I assume a steam room has the same effect? I prefer it over sauna

New comment by atum47 in "Codex Hacked a Samsung TV"

atum47 — Fri, 17 Apr 2026 03:22:18 +0000

My Philips smart tv started to give hints of programmed obsolescence this week, after 4 or 5 years. Besides the fact that I cannot install any real apps other than the ones built in this model (YouTube, Netflix and Prime). How I wish I could hack it and install another os. Honestly I don't think I have the time anymore to investigate this kind of thing. I decided to leave this comment here in hopes of someone pointing me in the right direction, if there's one. For now I'm thinking about getting a TV box and ditching the smart features all together.

New comment by atum47 in "Generative art over the years"

atum47 — Fri, 10 Apr 2026 03:27:03 +0000

One of my hobbies back in college was to write fun js fiddles [1]. It was super fun to have the time and curiosity to investigate something. I've been missing it more and more each passing day. I was super curious about generative art, procedural generation... I guess it is a negative term now, with AIs being able to create such complex stuff as video, audio and God knows what else. I was once working on a memes app where users could submit images. I was knee deep in how to identify duplicate images to keep my meme database "clean", so I was investigating cosine similarities... Few months went by and AI can do that better. Thats how ai feel now: AI can do it better, so why bother?

I gave up on Netflix years ago, never looked back. Went back to my old reliable external HD which I can plug directly to my TV.

See if you can count how many times the video "where do video games come from" appears in my front page.

I'm not popular enough to write a post about everything that is wrong with YouTube, from recommending the same few videos over and over again in different "categories" to ALL the results of a search being cringe shorts no one wants to see.

Show HN: Play Bang Bang against a neural network

atum47 — Fri, 13 Feb 2026 16:52:59 +0000

Browsing through some old projects I found this game I wrote a long time ago, back when I was super interested in NN.

My goal was to have the NN to learn as it plays against the player so they could have a chance of winning.

Now a days, with the work load of my full time job I don't have that much free time to investigate fun projects like this one.

I spent years doing that post processing on Photoshop, trying to increase realism on my archviz scenes, clients never went for it. They use to prefer the fake, perfect 3D look. Nice project, well done.

Don't know what happened. I stumbled onto a funny coincidence - me talking to a LLM about its similarities with MC - decided to share on a post about using MC to generate text. Got some nasty comments and a lot of down votes. Even though my comment sparked a pretty interesting discussion.

Hate to be that guy, but I remember this place being nicer.

Yes. Yes I was. Thank you for the wake up call. I was under the impression that he was talking only to me.

When you say nobody you mean you, right? You can't possible be answering for every single person in the world.

I was having a discussion about similarities between Markov Chains and LLMs and short after I found this topic on HN, when I wrote "I can share if you like" was as a proof about the coincidence.

I usually have this technical hypothetical discussions with ChatGpt, I can share if you like, me asking him this: aren't LLMs just huge Markov Chains?! And now I see your project... Funny

Android gestures need to be prevented in order for the game to work on mobile (drag finger from right to left go back). Nice game thought.

At some point I would like to add more features as you described in your article; feature detection, image stitching...

Here's the source code if anyone's interested https://github.com/victorqribeiro/customFilter

I was working on a image editor on the browser, https://victorribeiro.com/customFilter

Right now the neat future it have is the ability of running custom filters of varied window size of images, and use custom formulas to blend several images

I don't have a tutorial at hand on how to use it, but I have a YouTube video where I show some of its features

Yeah, but do they want to?
