Social recommendations and mentions

• Memory-safe sudo to become the default in Ubuntu

  The Lennart post about it explain it https://mastodon.social/@pid_eins/112353324518585654 He was comparing to "normal" sudo, but sudo-rs have the same problems he highlighted anyway. - Source: Hacker News / 7 days ago

• Memory-safe sudo to become the default in Ubuntu

  I think this post explains why much better than I can: https://mastodon.social/@pid_eins/112353324518585654. So yes, I am not saying that privilege escalation bugs are impossible if you have a different architecture, but like Lennart argues is that it makes them much more difficult to happen, especially because creating a proper setuid is difficult. Also there is a bunch of things that makes sudo especially tricky... - Source: Hacker News / 7 days ago

• Faster sorting with SIMD CUDA intrinsics

  I don't -- unfortunately not too well-versed in this field! But I was a bit fascinated with SWAR after I randomly thought of how to prefix-sum with int multiplication, later finding out that it is indeed an old trick as I suspected: https://mastodon.social/@dougall/109913251096277108 As for 64-bit... well, I mostly avoid using high-end GPUs, but I was of the impression that i64 is just simulated. - Source: Hacker News / 7 days ago

• The vocal effects of Daft Punk

  Marc added some extra flavor https://mastodon.social/@marcedwards/114454783708869207 > This article is the longest piece I’ve published on Bjango’s site, and it took a couple of years of research. I purchased around 25 pieces of music gear. I emailed Imogen Heap, and to my surprise, someone from her team got back to me and confirmed the exact harmonizer used on Hide and Seek. > It’s been a huge effort,... - Source: Hacker News / 8 days ago

• The strong case against Microsoft Bitlocker

• How to vibe code for free: Running Qwen3 on your Mac, using MLX

  Coincidentally, I just managed to get Qwen3 to go into a loop by using a fairly simple prompt: "create a python decorator that uses a trie to do mqtt topic routing” phi4-reasoning works, but I think the code is buggy phi4-mini-reasoning freaks out qwen3:30b starts looping and forgets about the decorator mistral-small gets straight to the point and the code seems sane... - Source: Hacker News / 12 days ago

• Someone at YouTube Needs Glasses

  I wish PeerTube had a "flagship" instance like mastodon.social [0] for Mastodon or lemmy.world [1] for Lemmy. The lack of a generalist instance with open sign-ups hinders the adoption. [0] https://mastodon.social/ [1] https://lemmy.world/. - Source: Hacker News / 13 days ago

• Ask HN: What are you working on? (April 2025)

  For awhile I've been working on an MPE MIDI controller called the Mosaichord. It uses a tuning system called just intonation, where the frequencies of all the notes are related to each other by whole number ratios. I'm using a scale that has 28 notes per octave. Keys are pressure sensitive. A few weeks ago I got a video of one of my friends playing it at a show: https://mastodon.social/@DesiderataSystems... - Source: Hacker News / 15 days ago

• Exercise before bed is linked with disrupted sleep

  According to this book foxes are light weight because they jump to capture prey https://mastodon.social/@UP8/114389122128299887 So far as my fox is concerned [1] I know it puts a lot of stress on my hindquarters (wants to be pronograde?) and to express itself wants to use a range of postures and motion wider than I find comfortable.

• Don't make it "like Google"

  I think I meant the same thing as you, see https://mastodon.social/@UP8/110417985807049704 Notably the Google app icons commit the same sin that many multi-colored designs make in that they don't prefer any part of the color wheel over other parts in a particular symbol which makes all the symbols look effectively grey. I think of Scott McCloud's critique of the use of color in Stan Lee-era Marvel Comics and how... - Source: Hacker News / 19 days ago

• Trump administration's attack on university research accelerates

  Back in the 1990s Cornell had three conservative newspapers and I regularly remember seeing speakers like P.J. O'Rourke and Dan Horowitz. Of course we had Pataki as Governor in New York back then. I came to Cornell in 1993 and felt really out of place and got interested in the far left and teamed up with my friend Harel to get all the left-wing organizations pulling in the same direction. Other people formed... - Source: Hacker News / about 1 month ago

• Debts, Tech and Otherwise

  I really liked Yvonne's reframing of tech debt as house work: https://mastodon.social/@yvonnezlam/112474946704366947 no metaphor is perfect, but I think figuring out who is impacted and how by decisions to rush or skip things is important. - Source: Hacker News / about 1 month ago

• Tim, don't kill my vibe

  Surely there is a middle ground where its at least possible to install apps that apple haven't approved[1]? I also like the idea of the _higher_ bar that the app store is supposed to have (not that this bar is always met), but the lack of any alternative is really crappy.
