Know some good shit on Tor? Let us know. Whether it be substitutes for clearnet services, or just the .onion domain for whatever, or just something cool.

What I found:
>privacytools.io site
>Invidious (YouTube front-end)
(Clearnet version: https://vid.puffyan.us/ )
Requires enabling certain scripts to work unfortunately. You can sign up and make a list of subscriptions though.
>Nitter (Twitter front-end)
>/leftypol/ (/leftypol/)

Some things I was interested in hearing about:
Post too long. Click here to view the full text.



Hidden service for snopyta.org
Basically an index of their services, and about half of them have a hidden service through Tor. I prefer the Invidious instance I linked before, but theirs probably works just as well if not better if you don't want to sign up for an account to keep a subscriptions list. The Invidious instance I linked before had registration while Snopyta's didn't when I checked.piratePirate

Hello lads, I'm looking to start a conversation on a topic that's been popping up alot recently, and will likely develop further as the technology gains more adoption. As I'm sure you know, robotic dogs from the likes of Boston Dynamics are being rolled out at police departments and military bureaus across the US, and I'd bet we see widescale adoption as the technology is fleshed out further.
So as a result, I'd like to start a conversation on the best feasible means, both expensive and DIY, to deal with these fuckers. With the advent of home-based 3D printing, easily accessible lasers, and other modern user tech, I believe there are a number of options available to us.
In the resistance against drones being used by the police in Chile, Argentina and now in Portland, lasers were used to incapacitate drone dogs during protests. However, this incapacitation *only* makes these dogs unusable at that single protest; any police department will simply repair their $75k digidog and send it back at the next protest. So, what I'm interested in is ways to make them *inoperable* for extended periods of time, whether physically or electronically. I was bouncing around the idea of somehow using very strong magnets to damage the internal electronics, but this may be unfeasible due to the size of magnet that would be needed. Other options that seem viable would be permanently damaging the optics being used by the dogs, but I'm not sure on the best option for this. As such, I'd like to open this to conversation. I'll be posting this thread here, as well as on a few other imageboards that may be interested and able to help in this discussion.

How about smoke, could that screw up the sensors on the device?

What about covert methods to disable these pricy toys?

Guns would draw the attention from the officers if they were used to disable these robots.


event paintball guns may work if it has optical sensors


then theyll just install little eye wipers…


paint isn't that easy to scrape off by simple wipers thoughanarcha-feminismAnarcha-Feminism


I’ve never wanted to violently destroy something more than these disgusting fucking robots


Just installed arch

What do I do now?


install gentoo




enjoy how ridiculously convenient pacman is
just install a bunch of shit you don't even need because why not

Hello tech, does anyone here know of a way to bypass public VPN/TOR blocks, such as those used on 4chan and wikipedia? It must be technically possible no? Any other anonymizing software that might not be blocked?

A Tor bridge? Like Meek Azure or Obfs4? Those are for disguising you at the entry node, not the exit node.anarcho-communismAnarcho-Communism


OP's talking about exit node blocks

Put a proxy at the end of Tor. I sometimes even use web proxies from within Tor Browser.


>Put a proxy at the end of Tor. I sometimes even use web proxies from within Tor Browser.
Based, what proxies do you use? For using wikipedia with TOR should I hire out a dedicated IP proxy with BTC or something? Or does that completely defeat the purpose of using TOR circuits dedicated for use with a single account?


I don't know why this didn't occur to me before, but you should be able to use 4chan through Tor if you use a 4chan Pass. Which requires money. It can be paid for with crypto, but CURIOUSLY not Monero.
I probably wouldn't give money to 4chan though. But it's a way to get around rangebans and shit, people use it to use rare VPNs that have permabans on them so they can get North Korea or China flags on /pol/anarcho-communismAnarcho-Communism

Hello there, /tech/ comrades.

I am passing by to let you know that a Matrix chat for /tech/ talk has been created! The chat has been added to the official leftypol community. This chat is meant to serve as a place to talk tech and programming in general.

Come join us! The link is: https://matrix.to/#/#leftylambda:matrix.org?via=matrix.org

This chat will also be hosting an SICP /read/ing group. That is, we will be studying the book "Structure and Interpretation of Computer Programs" and helping each other solve the exercises. For those unaware, SICP used to be the introductory textbook for Computer Science classes at MIT back in the day, and remains a cult classic to this day. It can be used as a general introduction to programming, but will also be rewarding for those more experienced.gentooGentoo

Macros are evaluated at compile time. Lisps are known for their awesome macros. You don't get to write any for SICP, but see pic. related for an example.

However, dynamic dispatch is dynamic, you can't do that at compile time. If you knew what kind of data you will have to handle at compile time, you wouldn't need the dynamic dispatch. Fortunately symbols are identical (every time you evaluate 'sicp, you get back the exact same value), therefore they can be trivially and more importantly very quickly and cheaply compared. With a "sufficiently smart compiler" it should be possible to generate very efficient dynamic dispatch. But it will depend on both the Scheme implementation and the code you write. I'm not sure if any actually does it.


Thanks for the pdf, I'll check it out.

What I was thinking of was the fact (with the impl. in the book) that the cost of dynamic dispatch for towers scaled for every operation as the height of the tower grew, which is much worse than the single indirection OOP languages usually have for virtual member functions.

While reading this book, I also thought about the fact that everything is a linked list. Isn't this horribly inefficient compared to classes with contiguous memory, where you can access any member in constant time? Are the lisp's out there smart enough to cope with this?

Don't get me wrong, so far it looks extremely versatile, but the lack of static typing, contiguous data and so on spook me.


Lisp has vectors (which are contiguous). The book's primary goal is not to make you an efficient lisp programmer, rather it is to teach general programming principles via lisp.
I wouldn't judge lisp based on the pedagogical implementations given in sicp.


Good to hear, it's just something my C++ autism has been nagging me about throughout

Signal decided to include a payment mechanism in their app based on some obscure cryptocoin which is located in the British virgin islands, a known tax heaven.

Them hiding their server commits for over a year sure makes sense now

Imagine shilling telegram.


It's a matter of which glowies are preferred, the choice of chat apps and ilk, so best stick to the old technology that works or what others in this thread already said.


Just use XMPP for chatting with people directly and Matrix for group chats. XMPP is proven and reliable and completely open.

Any programmers here? I thought about simulating a population organizing resources for a while. Nothing serious, just doing it for fun. Anyone tried that before in their free time? Do you have any conceptual starting points? I will start:

Type: Person
Attributes: sex, age_range
That is to predict how much resources they themselves need and how much work they can produce. All based on averages.

Type: Resource
Attributes: quantity, state
Subtypes: metal, mineral, wood, food
The attribute "state" describes for example if the resource has been refined based on some procedure. The mentioned subtypes have further subtypes of course.

Type: Product
Attribute: kcal, components
Subtypes: electronics, furniture, dish
kcal is supposed to represent the average amount of work exerted with the most efficient available tools available to produce the product.

Brainlet here, but for the "Too simple" etc etc didn't Cockshott make an open source program in Julia for planning?
Couldn't you anons use this as a base?


Cockshott has a github with some relevant code: https://github.com/wc22m?tab=repositories


yes that works but the question is scale


Write an OpenTTD script/bot or whatever


At such simplistic level you could just structure the whole thing on iterations, so you have a simple mathematical function that takes the current state as input and transforms it according to some chosen model to produce a new state which is then again fed as input. Then just iterate to see how it behaves through hundreds of generations.

Hello /techbros/ i want to create a textboard (or oldstyle forum) for a rather small group of users is there a way to host this in a decentralized manner it has to be as secure as possible
Software recommendations are welcome




>in a decentralized manner it has to be as secure as possible

Just use schemebbs or weabot on an onion website.


i second schemebbs

LM was the first OS I ever used for Linux and if you are openly making declarations of your laziness then I can't fault you. Hell, I use Gentoo on my desktop but i installed Ubuntu on my laptop just out of sheer laziness. Mint is a great Os though and I can't knock you for using it for the sake of laziness.


Fedora for desktop and Centos for servers.


Debian, because it just werks


Debian. Works for almost every use case from making old computers still useful to my daily programming work, container shit, server side stuff, etc. and has a massive community that ensures that you have reasonably up-to-date versions of every software within the linux/unix ecosystem.

Also it helps that at least some who use and develop for it still have an ideological inclination towards the FSF and real free software instead of being fronts for corporate shit (Fedora, Ubuntu, etc) or total sellouts like the user-focused ones whose priorities lie more towards being Apple clones in functionality instead of free software.
