Unrelated, but it reminds me of this C64 demo [1] I posted earlier this week: the whole thing in 17.8 KB.

And... it's gone. I guess mods don't like emoji in titles.

Can't blame them; it draws a bit more attention than normal.

New comment by guiambros in "What AI did to stackoverflow in a graph"

Both things can be true. SO was universally hated because they let (or actively incentivized) bullying run rampant and destroy the culture.

And yes, it's possible AI would have killed it anyway, despite its best efforts. But in this version of parallel universes, AI was only a catalyst. Its fate was sealed well before 2020.

No, of course not coincidence. It's just that people didn't have an alternative until 2021-ish. Users hated SO for many years prior, but had nowhere to go other than small niche communities. When LLMs came into play, it was just the obvious choice.

In an alternate universe, where LLMs didn't exist, I bet you SO would be equally dead by this decade. Someone better, with healthier values and a more welcoming community, would come up and steal their lunch.

Big fan of SW:KOTOR series. Would love to test Vestiges when ready.

You should consider creating the game on Steam, so you can start building your audience.

New comment by guiambros in "Why Switzerland has 25 gbit internet and America doesn't"

guiambros — Sat, 04 Jul 2026 04:56:45 +0000

You missed the point (and I should have clarified better). It's not that 1 Gbps is bad; it's pretty good, actually. And I do think Verizon is one of the least bad options.

The problem is that there's zero competition. And while many other countries have 2, 5, 8Gbps available, there's zero reason for Verizon to offer it, despite being a densely populated area.

And 1 Gbps has been the max available for 10 years. It's very likely in 2036 we'll be in the exact same situation.

I wish we had a model like Switzerland, where the fiber is centrally managed, and providers compete just to connect you to the network.

I live in NYC, one of the most densely populated cities in the world, and yet Verizon Fios 1 Gbps is my only option. I tried to upgrade to Fios 2 Gbps, but it's not available. Spectrum only goes to 200Mbps; no other providers in my area.

I have no idea if Switzerland is any better, but the US situation in 2026 is appalling. If we're this bad in NYC, imagine what someone in rural America goes through.

Dave Jones didn't spare words [1] on how insane it was to have a jellybean component changing specs so significantly, particularly the input voltage from 22V to 18V, the removal of offset trim, and more.

Well done! Reminds me of Atari's Asteroids, with a modern take.

New comment by guiambros in "Associative learning turns DEET from aversive to appetitive in Aedes aegypti"

guiambros — Mon, 01 Jun 2026 01:51:34 +0000

It doesn't seem the case; the study was made purely on behavioral conditioning. And mosquitoes don't live very long, so it's unlikely they'd learn this in practice, outside of a very controlled environment.

But there's a natural selective pressure, and it's plausible that mosquitoes would eventually evolve their sensors to become attracted to DEET, over multiple generations. And with each generation lasting only 20-30 days and a single female mosquito laying 300-500 eggs in total, they can evolve orders of magnitude faster than us.

It works well on Android. Just zoom in and click the number, and you can breakdown per state. Click on any state number and it breaks down per city.

Pretty functional design.

It's really unfortunate that FPGA development is still stuck in the 90s. The incentives between IP owners and hobbyists are so misaligned that I don't see the possibility of this ever improving.

The market is full of dark patterns, and vendors like AMD/Xilinx can pull shitty moves like what OP highlighted, knowing there is no decent alternative (Altera is another disaster). Lattice had the opportunity to fully embrace opensource toolchain and try to disrupt from the bottom, but they seem stuck in the middle, not wanting to commit one way or another.

I'm grateful to SymbiFlow, and IceStorm and others, even though they obviously lack support for proprietary hardware features.

Plus now you get access to Safari books, and you also have their online library, so virtually any books you may need are accessible for free.

(That's for the CS graduate program; not sure about others)

New comment by guiambros in "PyTorch simulator refutes an 18-year-old quantum theorem"

guiambros — Fri, 15 May 2026 03:16:32 +0000

What a horrible title. This has nothing to do with PyTorch (other than the relationship you mentioned).

A better title would be the Github repo title: "Computational Refutation of Quantum Superactivation"
