nsilvestri··on Glacier Mice
It had 13 glaciers pre-eruption, so perhaps "added" is doing a lot of heavy lifting :)
nsilvestri··on The Prompt API
This is the Soylent of written communication. Full nutritional value with an unremarkable flavor.
nsilvestri··on Anki ownership transferred to AnkiHub
Community focused organizations like this are hard to run without governance transitions. I think Anki brings value to the world and anyone willing to take on a leadership role in keeping it going should be given trust and grace to make the best decisions they can with the knowledge they have. I wish them luck.
nsilvestri··on Project Genie: Experimenting with infinite, interactive worlds
The bottleneck for games of any size is always whether they are good. There are plenty of small indies which do not put out good games. I don't see world models improving game design or fun factors.

If I am wrong, then the huge supply of fun games will completely saturate demand and be no easier for indie game devs to stand out.

nsilvestri··on Noclip.website – A digital museum of video game levels
In a similar vein, but for Old School RuneScape, is https://osrs.world/

This one is kept up-to-date with the state of the game world. Even includes full NPC locations and animations.

nsilvestri··on Roblox is a problem but it's a symptom of something worse
How dare this child be excited for a special event in his game!
nsilvestri··on Counter-Strike: A billion-dollar game built in a dorm room
"Fairly unprofitable [if you ignore all the parts that generate revenue.]"

I will admit that gambling $0.16 in skins on pro matches when I was 15 was a lot of fun. Maybe I'm lucky to have gotten away (relatively) unscathed, but I do have a little nostalgia for those days.

nsilvestri··on OpenAI Announces SearchGPT
I have never felt like my searches in other engines have been helped by AI. I hope SearchGPT changes that. My expectations are low.
nsilvestri··on FDA warns top U.S. bakery not to claim foods contain allergens when they don't
As someone who can't eat gluten, we look for that label because gluten isn't included as one of the mandatory allergens in the US. I would prefer if things were simply labelled as "contains gluten" because instead I have to evaluate the ingredients of things without a GF label to see if it's suitable.
nsilvestri··on Mitsubishi robot solves Rubik's Cube in 0.305s
Computers can generate optimal solutions to arbitrary positions. There's no need to apply the human-optimized ergonomic algorithms or methods that human use to speedsolve.

nsilvestri··on Webb and Hubble confirm Universe's expansion rate

nsilvestri··on CUBOTino: A small, simple, 3D printed, inexpensive Rubik's Cube solver robot
WCA Delegate here. The limiting factor generally isn't cost, but the need to handle cubes of various sizes and other puzzles entirely. Having a robot that can only scramble a 3x3 isn't useful for the majority of competitions.
nsilvestri··on My speed cubing page
Ah, whoops, the 2020, not the 2021! Should only be $9 at the right place. In my opinion, the extra couple dollars are worth it :)
nsilvestri··on My speed cubing page
MoYu RS3M 2021 is considered a better budget cube nowadays. Many people use it as their main, which is not something that can be said about the YLM.
nsilvestri··on Re: I Don't Use Copilot
For $10 a month, all Copilot has to do is save me a handful of minutes each month for it to be worth it.

Most of my current work is creating new React components. In these tasks, Copilot probably saves me 20 or 30 minutes a day on average. Often more. It's not always right, but often close enough, and I'm not committing my code without testing it anyway.

nsilvestri··on Show HN: Boring Report, a news app that uses AI to desensationalize the news
I disagree, as I think this would be useful to people with anxiety disorders who don't want to entirely disconnect from the news. Just because they may be able to logically identify articles and headlines as "sensationalist" doesn't mean their brain won't still kick off some uncomfortable physiological responses.
nsilvestri··on How Postgres Triggers Can Simplify Your Back End Development
The article mentions it at the very bottom, but I almost never reach for triggers because they are obscure places to put application logic. On more than one occasion I've been burned by not realizing that the code in the backend did not represent the whole picture of business logic. It's more complexity, requiring more documentation, adding another point of failure that probably isn't necessary.
nsilvestri··on NASA’s Double Asteroid Redirection Test Is a Smashing Success
You can derive it yourself. Dimorphos's orbital eccentricity is pretty low, meaning you can use:

mean_orbital_velocity = 2 * pi * semimajor_axis / period

As for the orbit around the sun, the parent body Didymos is about 100x more massive, so any change in the center of mass from this impact will have, in the short term, negligible effects on their orbit around the sun.

nsilvestri··on Poll: What's the best laptop for Linux these days?
I love the form factor, but the battery is my second biggest gripe with my Framework (after fractional scaling still not supported by many apps). Even after tweaking settings ad nauseam, I cannot get the suspend battery life to last more than 12-16 hours.
nsilvestri··on Sesame allergen labeling law has unintended effect: sesame in more foods
I can't eat gluten. I ate plenty of wheat growing up, and suddenly developed a problem digesting it at 18. I was on a full-gluten diet when diagnosed and still felt sick all the time.

So, as someone who was exposed as a baby, and was pretty much doing maximal exposure therapy, you need to write better test cases.

nsilvestri··on 2D Rubik’s Cube solution visualization
It does, but not elegantly: when a non-slice move is made, you have to rotate the 3x3 group at the center. You see it in the animation.
nsilvestri··on Ask HN: Do you recall any book or course that made a topic finally click?
3blue1brown's Essence of Linear Algebra: https://www.youtube.com/playlist?list=PLZHQObOWTQDPD3MizzM2x...

Many linear algebra courses struggle to bring the abstract concepts into an intuitive mental model, which is sad because I think linear algebra fundamentally represents fairly visually-oriented concepts. I never was able to put the pieces together before seeing the visualizations and animations of the numbers.

nsilvestri··on Meta Quest Pro
I believe I'll be able to replace my monitors to do my desk job with a VR headset within 10 years. Rather than having 2 monitors of different sizes and resolutions on a desk, why not just have as many virtual monitors with exactly the size, position, and distance I want? In fact, why have monitors at all? Just position the windows in arbitrary space in front of me.

Desktop computing with a VR headset is somewhat possible right now, but I am not quite able to stomach the resolution limitations of the Quest 2. I'm looking forward to devices like SimulaVR [0], which intend to fully replace desktop computing with a self-contained VR headset (plus a mouse and keyboard).

In my mind, there are two and a half problems to solve to make it possible. One is pixel density. It has to at least be equivalent (or very close) to our own eyes. Two is comfort, both physical (ventilation, weight) and health-wise (eye strain). Two and a half is being able to navigate without a mouse and keyboard, and preferably no peripherals, but I think I'm able to wait for that.

nsilvestri··on /r/StableDiffusion – Mod here – My side of the story
Reddit's ToS require all users to be 13 or older. There is no other requirement to be a moderator, and moderation is independently managed by each subreddit. Reddit tends to be very hands-off with interfering with who moderates a subreddit, for both better and worse.
nsilvestri··on /r/StableDiffusion – Mod here – My side of the story
Mods cannot edit posts, only admins. In my experience, however, reddit generally opts to fully remove any posts that break terms of service or guidelines. I've never seen a partial edit of another user's post by an admin with one drama-filled exception.
nsilvestri··on A beginners guide to Esperanto (2003)
Anecdata, but I've met a whole two other Esperanto speakers (that I know of) in the wild since I began learning it a couple years ago! It's not prominent with the general population, but I do think there are certain types of people whom are more inclined to learn it.
nsilvestri··on Linux on the laptop works so damn well that it’s boring
How does your suspend battery life work out for you? I'm running Ubuntu with Framework and even though I've done tweaked some settings I still end up with a dead battery after I reopen my laptop a day later.

nsilvestri··on 1Hz CPU made in Minecraft running Minecraft at 0.1fps [video]
Minecraft has a feature called redstone. It's "dust" that you can pour on blocks to create wires. These wires can be powered from in-game items. Combining two or more of these powered wires with some spatial positioning can give you an OR gate. Some of these power sources can be turned off if they receive power themselves. Those are NOT gates. With an OR and a NOT gate, the world's your oyster.
