Welcome to /tech/ THE RULES: 1. Please spoiler all porn and gore 2. Talk about something actually related to /tech/nology 3. Have fun! Required reading http://cryptome.org/2012/07/gent-forum-spies.htm Beginner Info If you would like to try out GNU/Linux because of https://itvision.altervista.org/why-windows-10-sucks.html, you can do one of the following: 0) Install a GNU/Linux distribution of your choice in a Virtual Machine (preferably using KVM or Oracle VirtualBox for newfriends). 1) Use a live image and to boot directly into the GNU/Linux distribution without installing anything (keep in mind that the performance of live distros might be very different than from distro that was booted from your HDD, as most distros are loaded in RAM and don't include the proprietary drivers for NVIDIA GPUs or up-to-date Mesa libraries in their isos). 2) Dual boot the GNU/Linux distribution of your choice along with Windows (make sure to install Windows first, as it can "replace" GRUB or other UNIX bootloaders, and troubleshooting of Windows replacing your bootloader of choice might be painful for people that just started learning about the Linux kernel) 3) Go balls deep and replace everything with GNU/Linux (you really shouldn't do this, if you don't know what you're putting yourself into, see: https://itvision.altervista.org/why.linux.is.not.ready.for.the.desktop.current.html).

BitChan Beta v0.9.0 Release Anonymous 11/15/2020 (Sun) 19:38:41 No.3162 [Reply]
The BitChan beta just got released and is looking for people to try it out. It's a decentralized imageboard that runs on top of BitMessage. You can create and completely control your own public or private board, globally moderate as an owner, add admins who can also globally moderate, moderate your own instance locally as a user, upload literally anything with size limits theoretically up to 100gb. Uploads can be sent purely over BitMessage or you can choose to use a hosting service. Uploads that use hosting are subjected to heavy duty protection: every file is zipped, encrypted/password protected, the zip's header is removed and random chunks of the file are removed before being uploaded. The removed parts are hidden in the PGP encrypted message that's sent over BitMessage. Once the upload is received the zip is put back together again, decrypted, unzipped and displayed in the thread. 100% of BitChan traffic happens over tor. Private boards prevent posting from all but explicitly added IDs. The permitted ID list can be edited by the owner at any point to include new IDs or restrict old ones. On public boards any ID can post until it is banned, but because of how BitMessage works, you can always just make another ID. Communications on every board are PGP encrypted. This means that even if someone somehow guessed the board name on BitMessage (basically impossible for reasons I won't go into here), they would be unable to read anything without also having the BitChan PGP symmetric password. Owners can globally change CSS, banners and wordfilters. Owners can even wipe a board if they want. You can join and create as many boards as you want. There's also a prototype steganography thread running alongside of every normal thread. The steg thread shows decrypted steg from jpg/pngs. There are also public and private lists. Lists are just collections of links to boards or other lists. Owners can do much of the same moderation, CSS changes etc. as they can do on boards. They can be updated and edited after their creation. BitChan is fully dockerized so it is cross-OS compatible, but has only been tested with Ubuntu 20.04 and the most recent version of Whonix. I could go on about all the features (there's a lot more), but I just wanted to give you a taste. It's surprisingly fast for text only messages that total around 20kb or less and using hosting services for file attachments, taking usually only a few seconds to a minute depending on how many people are on your part of the BitMessage network. https://github.com/813492291816/BitChan

A kiosk onion hidden service is now online. You can post and upload attachments. Test it out if you'd like. There's a bug report link at the bottom of the home page. http://bitchan5zleliwr7egmn4yskth5k6ofu6qbax3y4t45k3k2plt363nad.onion In kiosk mode you can only post anonymously. There's a help page which covers pretty much everything except for the peculiarities having to do with the kisok. If you actually go through the trouble (it's not that bad) of installing it you can very easily host your own kiosk instance (and if you run you're own version you get full functionality). Kiosk mode has a permissions system which allows for multiple passwords. There are password classes. Admins, guests, guests who can only view, guests who can post. There's a lot of options. How to safely host a kiosk: Pay for VPS via mixed/tumbled crypto, sftp bitchan.tar.gz over tor, ssh in over tor, extract bitchan, uncomment random hidden service lines in torrc, make daemon, load random onion address in tor browser, upload archive with custom onion address, and you're set. This kiosk instance has a 50 second post refractory period. It works with JS disabled. The kiosk disallows board and list creation, mailbox use and prevents using BM as an attachment upload method. The only things this kiosk instance allows is 1) view boards, 2) view threads (steg included), 3) make posts, and 4) submit bug reports.

Robi's MultiScraper tool seems promising but broken (at least for me) Anonymous 03/11/2021 (Thu) 00:59:35 No.3233 [Reply]
Not sure if this is the place to post this. Perhaps someone can give me some pointers, I attempted to use the MultiScraper tool that Robi wrote to do some board migration, however, the script seems to break and only can migrate one thread (files are not downloaded etc). https://gitgud.io/rb/MultiScraper Link to the project. I've attached some screenshots to show the errors that I'm getting. For reference I'm using Python 3.8 (Ubuntu 20.04), and have followed the exact instructions on the repo (this is a LynxChan to LynxChan migration). A question that I have that is not answered in the repo is however the target board should be established, in other words, should I make a blank board with the target board name, or just run the script and the script will make the board by default?

>>3233 Update: I removed inc from inc.download_file(f.path) on live 307 in lynxchan.py, this seemed to allow for files to be properly downloaded now, and one whole thread downloaded before getting this error again: "AttributeError: 'NoneType' object has no attribute 'cssselect'" Or check the screenshot
>>3233 Hopefully Robi will post here (or somewhere else) and explain exactly what his code is doing. I don't into Python, but I wrote a C++-based scraper that has been working for about a year and a half now. If I knew what his stuff was doing exactly, then I could probably relate that to my work and explain exactly how I'm doing it. Maybe it would help out some.
>>3235 Post your scraper somewhere?
>>3236 Sure, OK. (It's been readily available all along, actually). I just recently made a version that supports operating on a Raspberry Pi too. BUMP currently supports about 6 different types of imageboard software, and also kind of unifies the archives into a generalized, filesystem-based structure after download. So, it's kind of both a multi-scraper, as well as a generalization of the data storage that should enable easy script-based exporting to any type of other system -- no intermediate database required. >>>/robowaifu/8772

Arch Linux Eliteism Anonymous 12/31/2019 (Tue) 23:30:03 No.1221 [Reply]
Does anyone know why the Arch community is eliteist? Out of all communities, they are the most eletist and toxic, even gentoo isn't that bad, despite similarities.
10 posts omitted.
>>1221 >the Arch community is eliteist? proofs and we can have a discussion until then hide and sage
As a member of said toxic eliteist community, I can confidantly say that it is the package manager and the install process. God I fucking love pacman
>>1221 There is a flaw to Linux altogether and that is that it never really adopted a "plug and play" mindset for the user experience and that its very much a "read the handbook to learn how it works" OS. And because of this there is the common mistake in teaching Linux of making people belief that using Linux is just like switching from an IPhone to an Android phone and that all they is just the right distro and they are good to go just like on a Windows machine. Linux requires a learning period and a willingness to learn it before it can be used as a substitute for Windows or MacOS. Conveying that to people is more important than what distro they try out first. On top of that I think a good beginner book for Linux is mandatory as searching the Internet for answers to questions can suck ass and in some cases Internet isn't always accessible when installing a new system, especially for people who have just one computer.
>>3045 I'm not a huge faggot when it comes to operating systems, but I really love gentoo. Portage is so fucking nice, USE flags are the best idea any package manager has ever implemented. I hope CPU power continues to increase enough to the point that normal machines can compile software without perceptible delays, though even on my 8 year old laptop compilation isn't that bad unless it's some bloated piece of shit garbage software like firefox.
>>3050 Do you ever want to keep an old version of a package, because the updated version isn't working? How would you set that up with pacman?
