Does /tech/ participate in the Fediverse? Seems to me that this is the sort of social media we should be trying to get people into, even if social media itself is kinda trash.

I've always disliked social media, but after the news at >>>/leftypol/1066439, I've been considering getting into the Fediverse. You see, I would like the people who DO use social media (basically everyone) to be on better platforms, but I feel I cannot demand that from them if I cannot even use them myself. For instance, it would be disingenuous to ask Comrade Cockshott to start his presence in Mastodon after getting banned from fedbook if I could not be there to follow him and boost his follower stats. So..

So, /tech/, any thoughts on the Fediverse? What are some good instances and communities I could join? What are some people I should be following? What implementations are better, Pleroma, Mastodon, something else?

Also fediverse general.

Now that peertube supports streaming. When should I expect seeing one of you streaming silent hill there?

Get a mastodon account for that


I only stream good games tbh famalam


The e-influencers are getting real agressive with their Rokfin shilling this week. I am genuinely concerned for the future if they corral people into another fucking centralized Youtube clone.


Can someone explain to what the hell the difference is between PeerTube, D.Tube, and LBRY? I've already chosen PeerTube as my alternative to migrate off Youtube, and I'm really annoyed that I can't mount a proper argument against the other two.

Some anon here earlier was talking about making a standard API for chans/imageboards?

I assume the format will be REST using JSON as a serialization/marshaling format?

This would be great, if all standard chan software could implement this, possibly in addition to server side rendered HTML(optional) for the NO-JS /g/entoo-fags and torfags, people could easily write their own clients, maybe even a desktop app

I tried reading what NNTP was about, but quit because there is very little info on the topic. I assumed it was a protocol that was built on top of TCP, like an alternative version of zeronet.

Unless you're doing something highly specialized AND have institutional backing, there is no reason not to use HTTP over TCP.


NNTP was an internet protocol used for usenet articles before the world wide web was invented in the early 90s. Its basically dead but theres one anon here who keeps autistically focusing on it, same as /g/entoofags talk about disabling javascript in browser because Stallman told them to like 10 years ago


Vichan's code is littered with nntp protocol autism. It was never completed, afaik.


My assumption was, that NNTP articles were close to a drop-in replacement for IB messages.
After reading the RFC, I must admit NNTP's retrieval of articles by traversing a GROUP is less than optimal for throughput and the structure of NNTP is inherently incompatible with the notion of threads, unless the server automatically moved articles to a new "subGROUP".

However I believe we should think about adopting some NNTP concepts such as:
board hierarchies (perhaps with their own overboards)
ability to retrieve resources through WILDMAT

Observing NNTP also gives us the chance to avoid its shortcomings.
Being able to retrieve messages by their ID is undoubtedly a good thing, but you could implement a request for threads or even boards.

Are operations on threads and boards (and/or matching against messages by date) sufficient to negate the cost of linear traversal, or are there more elaborate data structures, that curb the overhead of common usage.


>Are operations on threads and boards (and/or matching against messages by date) sufficient to negate the cost of linear traversal, or are there more elaborate data structures, that curb the overhead of common usage.

Assuming the threads/posts are stored in a database, aren't most relational and even some non relational dbs based on B/B+ or modified B+ trees? If so average search complexity is O(log n), same for insert and delete.

Thinking about shit on the data structure level is a little too low level for web dev anyway since you would most likely be using a database/store someone else developed and its their job to make it efficient.

>board hierarchies (perhaps with their own overboards)

interesting, would the only point be for overboards?

>ability to retrieve resources through WILDMAT

is that some sort of regex search? Modern intelligent information retrieval techniques have probably obviated the need for that. Most likely using some sort of search engine thats already built although basic search functionality can be built pretty easily in a normal program.

How do I stop being neurotic about privacy? I'm seriously considering turning down a job offer just because thanks to this pandemic I'm going to have to use Google Meet every day for a few minutes. I don't want to give my data to the basilisk but this honestly feels like a losing battle. Should I just give up and perish like a dog?

>both by westerners and the Chinese themselves?
Yes especially by the Chinese themselves, ironically the companies involved are usually more honest in what they can actually do, but the media and state rely on most people thinking its way more advanced than it is. Much like cops how ask to search a car (even though it is against your rights) in the US, criminals are threatened with an imaginary god AI when no actual evidence exists of them committing any crime.


about facial recognition, you're potentially subject to it like all the time. It's much easier to live with the fact that the botnet has your name correlated with your face and your address and your phone and email, etc. From there you can stop worrying about hiding your face from every camera ever, and just understand what they likely have, and then work from there. Like if you dont want your computer associated with your face, thats one thing, get a computer for clandestine shit and one for your google meetings, and dont have them on around each other. If you worry that the gov will catch ur face while you're on your way to some maoist org or whatever shit you're a part of and worried about, then hide your face then when you're doing the sketchy thing, or reevaluate your priorities and risks and threat model.


if you want you can chain traffic from a few companies through each other, so that no one server company has your info.
Please understand that there is no "perfect" security in the internet.
VPS are mostly for avoiding passive surveillance, i.e. you can go to a site and it doesnt know your ip, and your isp doesnt know where you're going. This VERY GOOD, but of course doesnt help you if you're under active investigation because they can subpeona your connections, or if we assume that the whole of the internet is surveilled and effort is put into matching all inputs to outputs so as to maximize knowledge of everything. This is a goal of the US gov, but whether or not it's happening or possible at this moment, no one knows. If it is though, then Tor, I2p, etc. are all trivially breakable anyways because of traffic correlation, especially over time with fingerprinting.
I dont get the anti-vpn autists here, no one is saying they keep you safe if you do some thing very illegal and the government knows about it and wants to find out who. Literally people just wanna torrent stuff without their ISP freaking on them


As someone who works on projects involving facial recognition you'd need to be constantly surrounded by high definition cameras for the notion that "you're potentially subject to it like all the time" to be true. Maybe if you lived in some first world city like New York.


only some millions of people live in those cities :^)

but it's not just security cameras, some jobs require to you give them your data, and this can include images of your face

Comrades, we need a thread on privacy. Any decent activist should try ways of staying anonymous on the web and prevent being tracked by governments and corporations.General tips===* Use free software as much as you can.* Use GNU/Linux and keep it up-to-date, to be sure that you don't have unpatched security exploits* Don't use Flash Player, use youtube-dl instead for watching streaming videos online* Do not use Google, use DuckDuckGo or StartPage instead* Use a password manager like Keepass or for GNU/Linux users keepassx. Create new passwords for every site that you visit and use a strong password as a master password. A tip for easy remembering of your master password is to use a sentence. "i fucking love cookies and tits!" with extra capital characters etc. is easier to remember than some random characters and long enough to prevent brute force attacks of any kind.* Use the Tor Browser Bundle if you really want to stay anonymous.Firefox====* Go to Preferences -> History and set History to "Never remember history". * See for additional tweaks: https://github.com/amq/firefox-debloat and https://vikingvpn.com/cybersecurity-wiki/browser-security/guide-hardening-mozilla-firefox-for-privacy-and-securityAdd-ons-----------* Use uBlock Origin for preventing tracking etc. Bonus: use hard-mode to manually whitelist external domains on sites. Don't use uBlock but be sure to use uBlock Origin https://github.com/gorhill/uBlock/wiki/Blocking-mode:-hard-mode* HTTPS Everywhere* DecentralEyes: prevents CDN hosting from tracking you (Google for Jquery etc.)* Self Destructing Cookies: only allow cookies that you choose to allowOS==* Encrypt your hard drive or home partition at least* If you use GNU/Linux, you can try to restrict systemd or syslog from logging. * Use a distribution which takes security seriously. Also, be sure that you don't install a lot of things outside the repository. It will cover most of your needs.Real life tips===* Pay with cash if you canFeel free to provide tips to each other comrades!

Hello comrades, I have a quick question and I hope this is the proper place to ask.
plebbit spacing in honor of the ongoing gamestop short squeeze
Are there any good, privacy-respecting (but also free) www whiteboard services? Ease of use is a high prio since I need to get normies in on it.


Some days ago both DDG and Startpage.com stopped allowing search requests (at least) on Tor Browser with JS off, sooo…
Just leaving this here if anyone else were looking for an alternative, I hope this is a temporary bug of some sort because Startpage images is very reliable, and I had just gotten into the groove of using "" around terms and words on DDG onion to get quite good search results…

I'm not fucking enabling JS or using Google. Only forward.


DDG disallowing searches from tor w/o JS is alarming if true.

I have to disagree with everyone else in this thread, my experience has been that DDG has provided superior search results for almost five years now, and Google’s results have been in steady decline since 2007, becoming particularly shitty in 2003. My personal stance is that if Google provides you better results than DDG, you are the cancer that’s killing /b/, the algorithms were designed around you.


>Use Searx more than twice
>Rate limit exceeded
Wat do?

Also, I tested both my default Tor install with only the security preset set to "Safest" (no js) and my IceCat install with JavaScript disabled and a custom user.js from reddit via EFF's Coveryourtracks tool (FKA Panopticlick).

Can anyone explain why my IceCat install is marked as fingerprint-protected (1 in 4000 browsers have same fingerprint) and my Tor install isn't (unique fingerprint)?
I'm trying to wrap my head around why this is possible given Tor's whole point, so maybe I misunderstood what it does and doesn't do in the first place.


html.duckduckgo.com works without JS
The TBB approach to browser fingerprinting is to blend in https://blog.torproject.org/browser-fingerprinting-introduction-and-challenges-ahead

>Rate limit exceeded

Change Tor circuit, or use another searx instance https://searx.space

Many features are exclusive to synapse since they haven't been actually implemented into the matrix protocol yet or are undocumented.
>What element calls "communities" is actually an undocumented matrix feature called "groups".


Why would you say that blindly? Other clients have had e2e for years now.
>visit https://matrix.org/clients-matrix/
>check E2E row
- Element
- weechat-matrix
- gomuks
- nheko Reborn
- DittoChat
- Mirage
- FluffyChat
- Seaglass
- matrix-commander
There is also pantalaimon, a proxy dameon that can encrypt and decrypt E2EE for arbitrary clients.

Disclaimer: I haven't used any of them except for Element, and some like Nheko have disclaimers about their E2EE being 'proof-of-concept'. Read before you rely on it. I recommend Element for E2EE because at least it's been externally audited; I don't know if others have (only because I haven't checked).


Is there a client that supports proxying through Tor?


Good question

You're right, I apologize.

Reposting features from the feature-list that I think are critical for leftypol:
>E2E: weechat-matrix, Element Web/Desktop, gomuks, nheko Reborn, Mirage, FluffyChat, matrix-commander
>MMA*: weechat-matrix, Spectral, Quaternion, Mirage, matrix-commander
>VoIP: Element Web/Desktop, nheko Reborn,
>*: Multiple Matrix Accounts**
>**: Because it's pretty wise to compartmentalize online commie terrist activity like this from let's say your legal name or other uniquely compromising information (we're an open target of both state actors and nazis).

Will investigate tomorrow


It is caused by new changes in Kuroba itself
I've reverted them, for now

It may be related to the thread watcher, since when deactivated the app doesn't halt
If I have time by the weekend, I'll try to pinpoint the error


I believe its only happening when opening cyclical threads


The commits that introduce the issue are trying to enhance shift-formatting, where if a post is too long, the text is displayed below the thumblnail.

If we are to merge with Kuroba someday, this must be fixed, so I'll be working on it for the next week or two


Don't know if its related, but another new bug that I only started seeing around the same time as the crashing is OP images being wrong. If you have two threads, thread B will have the same image as thread A in the catalog view. Fixes itself if you open the error thread. Quite frequent too

Are javascript/typscript based single page applications better, or server side template based rendering? Do we really need something like react/angular?

I know /g/entoofags hate javascript because stallman told them to like 10 years ago but normalfags will complain if their front end experience isn't silky smooth with js animations and shit

Obviously some applications like darknet markets try to minimize or eliminate the use of javascript for security reasons.

server side html rendering also makes app deployment simpler since you don't have to worry about the front end and back end separately.

OTOH separating the front from the backend helps make a richer UI and also separation of concerns. Also makes it easier to swap out UIs

What does everyone think?

based. what language/framework you using?


scala with http4s and doobie, using postgresql. I'm planning on long term, if I ever get to it, adding redis for caching.




scala is too big brained for me tbh I had a hard time using it in school, but it seems pretty based


With enough pain, most programming languages eventually become usable.

7 posts omitted. Click reply to view.


so why does x86 still have so much power draw?


idk, not an expert on the power side. Ask a semiconductor engineer. Intel's chips are mainly used in desktop/server environments anyway so its possible using less power isn't a design priority for them anyway, or at least as much of one
open hardware implies open architecture


roughly speaking, more transistors generally implies higher power consumption.


>No RISC processors are up to performance level with AMD let alone intel


the process of decoding x86 into a risc-like language is extremely complex
