fp64··on Why Pascal Deserves a Second Look
Oh, I must have missed the real-world benchmarks and experience reports in that article. Yeah, it's not as slow as Python, who would have thunk.
fp64··on Pascal deserves a second look
I always liked Pascal but apart from being “nicely structured and thus good for beginners” the article doesn’t convince me that I should use it again. Probably would use Ada instead anyways, as that has some really good ideas and I always got along with it
fp64··on A near impossible literacy test Louisiana used to suppress the black vote
So I can vote in these places when I am on vacation there? Of course just once.
fp64··on Codon: A high-performance Python implementation that compiles to native
Not sure if I understand the license correctly, this is only for non-commercial (it reads "non-production") work, and otherwise requires a paid license?
fp64··on Nasir Ahmed's digital-compression breakthrough helped make JPEGs/MPEGs possible
Yeah, I thought about the video codecs but I wasn't too sure about even the majority there. But here, the quote might be at least much closer to reality.

And yes, I am sorry mixing DCT with entropy coding, I've noticed already during writing my comment, but didn't find a better way, and I see you understood what I meant.

fp64··on Nasir Ahmed's digital-compression breakthrough helped make JPEGs/MPEGs possible
>"Only a few image-compression standards not using DCT exist today.”

I am only aware of JPEG, actually. Can anyone help me? PNG uses deflate and not DCT, TIFF supports sort of everything (JPEG is uncommon but possible) but generally no DCT is used, GIF uses some RLE but also not with a DCT, J2K also does not use a DCT, EXR can use Wavelet as well but no DCT I'm aware of.

fp64··on Cardinal – Virtual modular synthesizer plugin
Ah, thank you. The Plug-in version is one of the main selling points of VCV Pro though, no? I have VCV as a VST plug-in, plus the ability to use any VST plug-in inside VCV which were for me the main reasons to purchase it (apart from wanting to support the project and buy commercial modules).
fp64··on Cardinal – Virtual modular synthesizer plugin
Does this offer anything besides circumventing the little set of features that VCV Rack charges money for? Am I subsidizing the development of this tool with my paid VCV Rack version?
fp64··on Creator of Zig asked "how to open a file in C++" in SO 15 years ago
I don't get it. 15 years is quite a while, if I think back what my own experience was then compared to now it's also quite a significant improvement. Also `std::ifstream` and `operator<<` is, in my humble opinion, stupid. If you make a story out of the fact that this lead to something in Andrew's philosophy, it might be an interesting post, but this I find just silly and borderline creepy.

EDIT: ah misleading title and post altogether, makes it even worse. Should farm some karma here so I can downvote

fp64··on Ask HN: What is in C-00000291*.sys?
It's not an anti-virus, it's intended to monitor all and everything on the machine. You^WAn attacker might want to hide what you're doing and thus it runs at that level.
fp64··on Sljit: Platform independent low-level JIT compiler
2-clause BSD vs LGPL-2 can be an advantage, depending on your perspective
fp64··on My .gitconfig File Dissected
Nice to see other people carrying on with ci and co aliases as well. I don’t really remember, co goes back to cvs no? ci as well I think?
fp64··on Gruen transfer
When I was a little kid, my mom often took me with her for shopping. One time there was a big barrel full of some cheap products, and bored and weird as I was, I started sorting and stacking everything in the barrel. Looked really nice. At some point a clerk came over and explained to me that this is not in the best interest of the shop, as people are more likely to buy stuff if it's in this cluttered mess, as it's more inviting to quickly grab something. For some reason that made sense to my 6 year old self so I happily abandon the stacking and moved to something else. Note, I'm generally rather a messy person. Maybe it's the fault of that clerk.
fp64··on Show HN: Elles – A nicer /bin/ls
>It differs from eza or lsd in that it has a slightly different feature set, and makes some different choices about various aspects.

Can you elaborate? Eza supports icons and I guess I prefer its color scheme, but difficult to judge without installing Elles

fp64··on Low-latency scripting for game engines
I don't have an answer either, but I've seen people who want to use bytecode/a VM using RISC-V just because it's well defined and tooling is already there. This has less to do with RISC-V hardware, or even really the fact that it's RISC-V, and more with using a simple bytecode and VM - e.g. JVM could also work there, but the Java ecosystem comes with what some people consider considerable pain.
fp64··on Drone Flying 101 – An interactive tutorial for beginners
Well, at least in the City of LA it's pretty much illegal to fly FPV (unless commercially, with very involved regulations). But that's also LA so..
fp64··on Drone Flying 101 – An interactive tutorial for beginners
If I recall correctly, the wording is "people and structures". If you want to fly close-by (10m or so) buildings and people, you can file for a special class/permit which requires an in-person exam. I might do that at some point, but haven't yet. Otherwise it's about what you said, couple hundred meters.

A 5" fpv quadcopter is already terribly dangerous, it happily pulls up to 50A, goes above 100km/h easily, and the rotors shred through flesh like butter, so it makes sense to at least regulate it somewhat. When I started, I had drones fall out of the sky because my battery connection was not firm enough and while I have by now quite some confidence in my soldering and building abilities, that's always something that can happen, so I naturally stay away from roads, regardless the rules.

For flying 5" drones, I usually take a trip to the country side where there's plenty of space. It's already stressful enough, and that way you can enjoy your flights much more without endangering people. Nobody ever asked for my permit, though, and nobody ever measured my signal strength and asked whether I have the required HAM license (which is far more involved getting). I don't fly in densely populated areas, at least not with my bigger drones. Sub-250g drones are barely regulated, and while they can hurt as well, the risk of serious injury is quite low - so you can try tinywhoops (which come even under 50g)

fp64··on DuckDuckGo was down
I'm sorry, I did not realize that complaining about big corporations using their monopoly was considered political and ideological now, but I suppose it makes sense. Please excuse my previous comment, I agree it's not helpful, and I should have resisted the urge to voice my frustration with the direction I see the internet heading
fp64··on DuckDuckGo was down
You're supposed to get your information from big platforms exclusively, otherwise how would you be able to see all the nice ads and "curated activism"?
fp64··on Drone Flying 101 – An interactive tutorial for beginners
I am a registered pilot. Had to do an online course and learn about restrictions, took an hour and was free and is valid across most countries in EU. Most stupid restriction is that for FPV, a spotter is required. But if I stay away from people/buildings I am permitted to fly up to IIRC 6kg drones
fp64··on Underwater acoustic analysis reveals unique pressure signals – Revisiting MH370
Try replace each instance of “we” with “I” and you will notice it will sound weird and narcissistic. At least that’s how I (we) feel
fp64··on Growing sodium chloride crystals at home
When I read about growing crystals online, I always have to think of the old 4chan "prank" that under the promise of beautiful crystals instructs the unsuspecting reader to brew some chloramine gas.

fp64··on Germany solar power output jumps to record highs
The articles says the hot water _threatened_ a shut down. Did it actually happen to shut down because of the water temperature in the summer month in 2022, or was this FUD?
fp64··on Germany solar power output jumps to record highs
Why? I would expect it to be comparatively chill, as it should be running mostly constant and reliable?
fp64··on Protecting your email address via SVG instead of JavaScript
Crawl every link, now including SVG, and grep all 'mailto:' does not sound super sophisticated?

    wget --recursive --quiet $BASE_URL && grep -roh 'mailto:\([^"]*\)'
works on the example and just prints the email
fp64··on Protecting your email address via SVG instead of JavaScript
I don't get it, I can just curl the svg and grep for mailto?
fp64··on Ovid's myths of macOS: password entry dialogs and the death of Semele
You can draw whatever you want onto the screen, you can not just prevent someone from drawing a little lock icon (maybe through copyright but malware authors wouldn’t care). Think of a video game, I can choose the color of any pixel on the screen. That’s the problem
fp64··on ViHN: Vim for Hacker News
There should be a couple command line tools to read HN, this way you can even stay in the terminal and don't need to switch to the browser

Switching to my browser, navigating to HN, and checking the first page (and going back if nothing interests me) already does not require me to touch my mouse and can be done with very few keystrokes. Typically, I visit HN when I'm waiting for something to complete or similar, though, in which case I anyways happily move my hand to the mouse, as I'll be _browsing_ for a bit
