The Advent of Code approaches once more. Is anybody up for another round?

yeah I'll try to make time for the first week at least

Part 1 was easy, but part 2 was probably the hardest day1 puzzle of any year.
I wonder if Eric was trying to trip up ChatGPT with this.

You can still use the leaderboard in the OP for this year's calendar, by the way.

Day 2

It's a shame Purescript doesn't have a well-maintained and usable native backend, as I find it nicer to program in than Haskell. There's been a few attempts, but nothing's stuck.

Show me your strongest fizzbuzz

>>3288
The only thing I can imagine that would be of similar "quality," would be FizzBuzz: Enterprise Edition.

I cаme up with а pretty clever wаy of implementing the toggаble thumbnаil thаt's on tc аnd most other imаgeboаrds, without using jаvаscript․

The "common" wаy of doing thаt is using а checkbox input аnd the CSS "content" property․ The problem with this method, is thаt pseudo-elements аre not аdded to the DOM, meаning you cаn't right click the imаge аnd sаve it from the context menu․

Using аn ifrаme for this like:

＜body＞ ＜а href="lаrge․jpg"＞＜img src="thumbnаil․jpg"/＞＜/а＞ ＜/body＞

doesn't work becаuse ifrаmes cаn't аdjust their size to their content, аnd HTML documents cаn't even define their own size․ BUT, SVG cаn․ SVG аlso supports some HTML-like feаtures, such аs imаges аnd links․ When аn HTML object element hаs SVG аs its dаtа, the object element will аctuаlly tаke on its size(side note, the img element doesn't support "nested imаges" within SVG)․ So аll together you cаn hаve this:

＜body＞ ＜object dаtа="thumbnаil․svg"＞＜/object＞ ＜/body＞

thumbnаil․svg:

＜svg width="160" height="120"＞ ＜а href="lаrge․svg"＞ ＜imаge href="thumbnаil․jpg"/＞ ＜/а＞ ＜/svg＞

lаrge․svg:

＜svg width="800" height="600"＞ ＜а href="thumbnаil․svg"＞ ＜imаge href="lаrge․jpg"/＞ ＜/а＞ ＜/svg＞

I don't care who made some technology, as long as it's useful. Guaranteed lossless is nice. One use case I can see webp being undeniably useful for is scaled downed thumbnails. Since there's down scaling, loss is unavoidable, but it's way better than jpg and has a smaller file size too.

SVG is a cool, but underutilized format. The most appealing feature to me being that it's possible to have text within an SVG image be directly copyable. It would be really useful for stuff like tables and graphs because of that, but there isn't any program that makes creating those simple, while also preserving text(inkspace is art focused, and google drawings doesn't do the latter). Pretty much any monochromatic art would also work as one, but it hasn't caught on anywhere except the logo space.

Might as well expand the scope to storage formats. Just yesterday, I found out about M-DISCs, a disk format that can supposedly last 1000+ years, depending on the storage conditions. It's the longest-lasting, commercially available form of storage(that I know of).

For those interested in data preservation(which I would think is most people here), isn't this enticing?

Reference manager is gui aids. You get a spreadsheet with macros as an email attachment. It uses a whole bunch of proprietary and in-house libraries you don't have installed on your machine. As far as I know, there is no way for you to know what those are without asking whoever you got the spreadsheet from to screenshot their reference manager. It should be written in the god damn code what libraries the code uses.

Nvidia to make Arm-based PC chips in major new challenge to Intel
https://www.reuters.com/technology/nvidia-make-arm-based-pc-chips-major-new-challenge-intel-2023-10-23/

Besides Nvidia, AMD, Qualcomm and a few others are gonna join the ARM fray. I'm kinda interested in what Nvidia is gonna put out, and whether an "all green" system will have any unique advantages. The novelty factor alone is enough to get me interested. On the desktop, there will hopefully be a standardized ARM socket, since motherboard manufacturers can't possibly make 10 different kinds for each generation. I really hope this doesn't herald soldered on CPUs.

>>3010
>subtopics pertaining
You mean restoring vintage computers? There's a decent amount of people into retrocomputing (not on TC but elsewhere on the internet), and you don't even necessarily have to know anything about programming to do that. In fact having some soldering knowledge will probably be more useful since you'll probably need to replace bad capacitors and such. But I'm not sure what people do with them once they get it running.

>>3011
Good point haha, I guess the only real thing you can do is mess with software formats that aren't compatible with today's computers. I have a lot of old floppy discs I'd love to check out. Maybe even buy some vintage games and run them on their original hardware for that authenticity. I'm not too sure haha, but I know for sure it spikes my interest. What interested you and what subtopic do you thrive in?

>>3012
>what subtopic do you thrive in?
I wouldn't say I'm interested in a particular subfield more than any other, I find all of them interesting and will eagerly seek out opportunities to learn more about them.

>What interested you
I don't really remember. I think it's just that I spend a lot of time on the computer, so it was a motivation to know enough to be able to have unilateral control over my environment. And to be able to confidently mess around with things, you need to know how they work.

My issue with programming is that I am extremely stubborn and can't focus on things that I have no interest in. So, in python class for example, when they tell me to code something that figures out how to perform some sort of function based around division of numbers or whatever, I just lose interest. If the language were written in such a way that classes, objects, strings etc were called "swords", "spells", "dragons" etc I would be more mentally stimulated and pay attention...

If you have an old smartphone you're not using anymore but that still works, you could throw Termux on it and just use that until you have some more spare money. I don't know how secure that would be, but the handful of posts per day that you can expect from a fledgling image board shouldn't be a problem for any phone from the last 5 years or so, unless the software is very poorly programmed and uses too much RAM.

Which imageboard software are you going to use, btw?

My imageboard is actually online right now. I blog posted about the whole process in bits and pieces.

Last night, my computer abruptly started having DHCP issues while using a wired connection(moca); over wi-fi everything is fine. Decided to wait until the next day to see if it fixes itself. It didn't, so I restarted my router and reset winsock and ip and all that on my computer. That allowed me to have an ip6 addresses, but for some reason I couldn't get an ip4 addresses. I tried every thing I could find in guides and even asked chat-gpt. Eventually, I gave up and set my ip4 address, gateway, subnetmask prefix length, etc. manually.

I don't understand why crypto(currencies) are always intertwined into these things. I bet if DHT was reinvented today they'd find some way to shoehorn cryptocurrency into it.

>>3272
>We're reinventing the hosts file?
I2P does, yes.

>I don't understand why crypto(currencies) are always intertwined into these things.
Normally I'd agree crypto involvement is superfluous, but for this use case it makes sense. Domains names are an intrinsically valuable thing, unlike a torrent's location on a DHT. More than one person is gonna want the same domain, and a first come first serve approach would enable squatters too much.

Small addendum, don't use a pre-release version. It should say 'latest'.

>>2800
Another addendum, with the release of version 0.5, those peers wont work anymore. You should check a recently updated page in https://github.com/yggdrasil-network/public-peers

Also, you might have to look in C:\ProgramData\Yggdrasil and update the configuration file there too.

I think you mean room-temp SUPERconductor, you wouldn't be posting on TC without room-temp semiconductors.

Replication attempts have been mixed, but theoretical simulation has shown there might be something to it, so it's not a complete hoax.

The only communication between client and server occurs through LSP, so there's no security issue here?

>>3237
The point I think he's making is that there's way more more "semantically meaningful" information handled by the client (i.e. text buffers, codebase metadata, etc) with the "LSP" (specialized client + RPC mechanism, really) approach, which might make it easier to leak remote data (either intentionally or, say, by local caching and whatnot), as opposed to the desktop streaming approach, where all you have is a bunch of pixels from your remote screen and all of the meaningful state is on the remote end.

>>3237
At my dad's job, he uses all kinds of software, not just an IDE. Database managers and all kinds of built-in-house stuff. They also use Excel files stored in Windows network folders, and stuff like that. None of that can be accessible from his host OS.

>>3238
Yeah that's fair, although I find it hard to imagine a threat model where an adversary can access in-memory text buffers but wouldn't be able to just capture the entire framebuffer (thereby accessing remote content). Usually the threat model with regard to thin-clients for FAANG companies is to avoid any code hitting disk, which is fairly easy to guarantee even with an LSP-type approach.

i run a separate machine for my file server because i found out i don't like sharing ram and bandwith with the outside world. i capped the server's bandwith at a bit below my total capacity so it can do it's thing and it never causes me any trouble.

I am trying to read a handful of ext4 formatted drives from windows. However, since I used some specific format parameters so I could save disk space, some of the linus fs readers don't work. This one called ext2fds actually allows you to mount drives right in windows but it only works with the one partition I formatted with default parameters. Another, called DiskInternals Linux Reader, does work but only lets you browse the file sytems in their standalone program. You have to "save" files you want to copy over to use them normally. Real round about way of doing things but oh well.

I never cared too much about the X vs Wayland holy war, but today I installed a recent Ubuntu, since I needed it for some software.
I just slapped Xubuntu desktop on top of a default server install, which gave me Gnome for some reason.
When connected via an old KVM it would only allow me to select 1024x768 as resolution, and apparently there is no way to override the mode in Wayland and the only solution proposed on the internet is to go back to X.
They've been touting it as the new, 100% production ready, absolutely superior software for what, 5 years now?
And it can't even do a simple thing like custom modelines.
What a load of shit.
And while I'm at it, the gnome display manager is shit too. If the user has passwordless login enabled I can't even select the desktop environment to start in X mode.
Solution according the internets? Well you can't do that either fuckhead, just have a password.
And if you happen to have a long MotD it hangs for a minute before logging you in, displaying parts of it.
Probably because it wants to show you the entire thing and give you time to read it, but there is no way to skip, and then when it gets to the last chunk, it just shows it for a millisecond and then logs you in.
What a fucking shitfest, especially considering these projects are heavily backed by the likes of red hat and other tech giants.
It's like modern software is purposefully built to be bad.

Although I have to admit that I kinda like the visual theme used in Ubuntu.
Looks a bit like late 2000s Mac OS, but damn, skeuomorphic designs in this day and age are such a breath of fresh air.

>these projects are heavily backed by the likes of red hat and other tech giants
Not really. I wouldn't call Red Hat a "tech giant". Yeah, they're owned by IBM, but that's a has-been company. I don't know how often Gnome(Wayland's real reason for existing) is used in the corporate world, but I'm certain it's not common-place. So even for Red Hat, it can't be that high-priority. FAANG couldn't care less about Wayland.

>It's like modern software is purposefully built to be bad.
Xorg isn't good compared to its common, proprietary equivalents. Tangentially related, but GTK also isn't good. There was no golden age of desktop Linux.
