1772903255844772.jpg - 5.95 KB (150x150)

Im stuck trying to develop a way to display featured threads on the index of my site for my imageboard backend. The only method i can think of that doesn't involve a clusterfuck of code is to query the database for every top post anytime a user logs into the index, but that still sounds awfully inefficient considering how minimal of a detail it ends up being. Any tips for this sort of stuff? I tried to look at how vichan does it but i didn't really get it tbhdesu.

Your fortune: Outlook good

>>1909 I have used imagemagick for a few things, including making captchas and thumbnails for an imageboard. my advice, if you don't want to post code, is to initially disregard the documentation for your language's port, and instead consult the c/c++ documentation, and/or the command line interface. once you have found a way of doing what you want to do with either of those APIs, you can look up how to translate that to whatever language you are using there are lots of examples on how to do things from the cli, specially things like making thumbnails, striping metadata or querying properties (width, height)

>>

this thread is making me doubt how i handled images in my own abandonware, with imagemagick rce and all...

>>1915 it never crossed my mind to lookup the c documentation, ill be sure to look into that. i still feel embarassed with the current state my code is in rn, maybe ill make a git page for it at some point. >>1916 yeah no kidding, the fact that it even has vulns like that is just lame, totally kills my interest in using it.

There are alternatives written in rust and zig, which guarantee things like bounds-checking (when compiled with the ReleaseSafe flag in the case of zig) that would've prevented that cve: https://github.com/image-rs/image https://github.com/zigimg/zigimg The problem is that neither of them have bindings to other languages or a cli. The good news is that both zig and rust support ffi through the c abi, which means that you can expose a c interface that will then be available to any language that supports calling c libraries (python, javashit, etc.). If you only need to do those three things (query dimensions, remove metadata, generate a thumbnail) you could write that in either zig or rust using these libraries, expose a single c function like "Result processImage(const char* data, unsigned len);" and then call that from whatever language you're using.

>>1918 that sounds like an interesting solution, but way beyond the scope of my current project lol, i feel like it would be better as a standalone project rather than just another component for what im making.

I did my first crackme. I did it with Binary ninja, it was quite easy, I only had to modify a couple of values in assembly mode and modify some conditions. happy If anyone is interesed, you can find a lot of crackmes here: https://crackmes.one/

can anyone point to past haskell vulnerabilities? language specific, focused. (for educational purposes) I've looked their bulletin, and saw only 3rd party issues with XZ, lib supply chain attack.

Thoughts on 4chan's source code? https://github.com/4chan-org/4chan

>>

Are there any actual advantages to using Yotsuba over something like Lynxchan, Vichan, Jschan, etc?

>>

>>1850 I highly doubt it. From what I can tell it's quite outdated and poorly supported. You're very probably better off just using one of the options you mentioned.

>>

>>1844 "I already know my IP, dumbass"

>>

>>1850 Vichan is dead

>>

>>1850 I read a little of the source code back when it got leaked after the hack, and it is quite different from the conventional open source imageboards. The way something like Lynxchan works is that posts are stored in a database, and then when a user wants to see a thread, the program fetches those posts from the database and sends them to their browser, and caching is done between some of these layers to speed up the process. Yotsuba, for the vast majority of user requests, skips the database step entirely: each thread is just a file (.html) that is served statically and modified in-place whenever someone posts something; this is way faster than even caching database queries like Lynxchan does. Although the technique works, from a programmer perspective this is ugly, clunky, error-prone, unmaintainable, etc. so personally I don't think we are going to see established projects adopting it. Most imageboards don't need scale, so it's reasonable that people prioritize readability and maintainability. We are more likely to see someone writing an imageboard with LevelDB or Cassandra than re-implementing Yotsuba.

Anyone know a free VPN add-on for Firefox with lots of IPs/servers? I only know UrbanVPN.

I use Proton, but I’ve also always paid for it. I don’t know how it runs in the free version.

I'm fairly new to messing with my NAS and using Docker to install a program. Does anyone know how to set up Gluetun with Mullvad. Mullvad dropped support for Openvpn and I dont want to run qbittorrent on my NAS without some sort of VPN in the same container. I just cant get the projects to work on my Synology no matter what I configure cry

>>
1000022410.png - 93.55 KB (897x368)

According to the github page for gluetan, it supports Mullvad using Wireguard. Is this an option for you?

>>

>>1877 it is, I'm taking a break from it right now. I also just removed tailscale from my NAS as I dont think I want to use conflicting VPNs. I'm too tired to delve into this more tonight


opti990.jpg - 23.70 KB (334x334)

Silly question for a stupid build of mine. I have a very small chassis (Optiplex 990, 2011 sff workstation) which I have crammed modern itx hardware in, and 4 HDDs (2x3.5", 2x2.5"). It has ~3-400W continuous power draw, depending on what it's doing. The airflow is really bad in this chassis. The drives and the mobo take up the entire top, with no room for any fans larger than 40mm. No side fan mounting options either. The bottom has room for one 80mm. I have a big 80x40 fan (server salvage) and some 40x30s. Right now, the 40x30s are feeding the CPU's air cooler. There's small holes in the ducting to blow air at the VRM heatsink. No significant cooling for the drives yet. GPU and PSU get ample cooling, since they're in the path of the 80mm. Currently, all fans are in intake. I know that's what some servers do, force air in to compensate for poor paths. I can do this to some extent, but at over 20-30%, these fans are too loud to be in the same room as. Currently working on adding ducts to get more of the air from that single big fan to the rest of the components. Thinking of adding foam to the chassis as well. I know this won't reduce the noise much, but hopefully it should lower the pitch a bit? Anyone done anything like this, any tips to share? I know it's an outrageously stupid thing, I have and can build a significantly better chassis, or add holes to it to mount a lot more fan, but I'm quite fond of this one and I like doing silly things.

Any Gentoo Friends on this board? If so tell me what you love or hate about it. What USE flags do you use? In the meanwhile I will post some of my favorite Gentoo Desktops!!

all the qt packages are blocking each other.

How do you guys keep your system nice and tidy? Personally I just --depclean and eclean-dist/pkg/kernel but I was wondering if there was anything else to keep in mind

What's the advantage of Gentoo over Arch or Void? I understand a bit about Gentoo, like how it's source based comp and ability to tailor it to your hardware, but is that all? If your hardware is only 5 or 6 years old, then is Gentoo worth it? Asking because I'm deciding between building a cyberdeck using Radxa Q6A or buying a Thinkpad from around 2022. Will use it for watching anime, reading manga, playing emulators and Morrowind/Oblivion (original, not the shitty version), and general use.
