This is the type of thread that you can write in every time you visit the site! You can do anything from use this as a personal log for your project, to sharing what you're hacking on at the moment, to critique something some else did in the thread, or request help with a bug you're struggling with. I'm looking forward to hearing what you guys are up to!

>>910I made a bit of progress on this project. I've got a working OpenGL ES2 context using libdrm, and I've rendered a blue screen to it. The program is mostly copied from various tutorials all be it with some stylistic changes and offensive programming. I've found a few blogs and some official documentation which should let me improve on it more. I plan on doing some literate programming to improve my own comprehension. Do any of you have any suggested tools for this? I've found noweb and CWEB, but I've also seen a number of modern takes on the idea in my brief search.Also I wrote a little partially broken responsive menu for a imageboard over at >>919, it's been awhile since I've written any CSS.


>>923I forgot to post a update yesterday, I made a little progress with my literate programing venture using noweb, and wrote a "Red Yotsuba" theme for the imageboard menu I made the other day just cause.

reading capital. writing a script for a friends short film. learning GURPS. but mostly just working. feeling lonely and aimless but ive been worse. just trying to not get caught in the feeling that everything's going to inevitably spiral cause that ends up being a self fulfilling prophecy more often than not.


>>2488oh, this must have been merged from /tech/, i thought it was a general hobby project thread

Don't worry we'll make an AI that detects other AIs which will cause a neverending feedback loop giving us the one true AI


>runs on their server and you can't have the trained network
bullshit. openwashing.


AIs have blind spots.

Alpha Go never reached one specific node that Lee forced it to play on fourth game.

OpenAI five was defeated by dragging the game & punishing their gold sharing tactics with stronger core heroes.

Alphastar was defeated by fucking cannon rush on the corner.

libratus had bugs on various turn spots. I think it was pairing turns but can't remember anymore.

deep learning AIs will obviously have upper hand when it comes to time it takes to reach 'expert level of play' but I think humans will be always able to outwit it…unless they actually 'solve' the problem space completely.


but think about how stupid people on social media are. corporations often use marketing (which includes twitter accounts) to incite identity politics and keep the working class separated, and what's worse is that it's considered legal and not corrupt at all.


I would say such polarizing marketing is side effect not the main goal of porky AIs trying to get most exposure on social media.

I am sure there would be an interesting way to hijack their bot to our advantage somehow.

Maybe NOVIDEO is going to try making good cards again now that AMD is back.

Exactly the same thread exists on /g/
It reached 300+ replies so there's another one about the topic.
Why create an identical thread here, when the same topic is being discussed elsewhere, by more people? We should be discussing things that aren't being discussed on other chans/boards. Besides, discussing consumer stuff and companies is really really boring.

But de-botnetting isn't.
>If you don't care about gaming or only plan on emulating old consoles, an old Nvidia card and the completely FOSS nouveau driver or a CPU with integrated graphics would be better.
I'm interested in emulating, tried with lattepanda and raspi, but it could only handle PS1 games. I'd like to emulate ps2 games, at least. So which used nvidia card would you recommend for the purpose?


either buy a cheap optiplex and take 1650 or something in the same range if it's affordable in your country,


Afaik only cpu matters when emulating (except for RPCS3, which can handle multicore too I think), someone correct me if I'm wrong

Unless you want to deal with inefficient intel housefires which only have a bit better single threaded performance but overall are worse you should get a zen 2 ryzen (not zen 1, those are from before amd made the jump to 7nm and are pretty bad compared to zen 2), ideally higher end and used, or one of the newest ryzen

Though this answer is about emulation in general, if you only care about ps2 my shitty ass amd bulldozer housefire can handle it so far


*or one of the newest ryzen if you've got disposable income


Praise Israel.

/g/ had a good idea for once:
We need a third option to the dichotomy between the fascist commie NIH philosophy of the FSF and the boot-licking brown-nosing philosophy of the OSI.
>OSI: in an ideal world, all software should be libre, but good software is more important than libre software, so when proprietary software is better than libre software, it should be able to cannibalize the libre software to make itself even better
>FSF: libre software is more important than good software, and therefore libre software is ALWAYS better than proprietary alternatives, no matter how many features are missing, and anyone who uses proprietary software should be harassed until they change their mind, and libre software should never promote proprietary software, not even for interoperability

What's the commonality that necessitates this dichotomy?
It's the fact that both the OSI and the FSF respect laws around proprietary software.
>OSI: those laws are kind of unethical, but it's okay if you want to license under them and steal our shit, your work is better after all
>FSF: those laws are unethical, so if you're going to license under them, then the only way to simultaneously avoid breaking them and retain user freedoms is to not use your software or even acknowledge its existence

I present the MAOSS. An idea for a gang of criminal e-thugs who use violence to force proprietary licensors to forfeit their IPs against their will so that users don't have to choose between software that works and software that respects their freedoms.
>oh, you're going to license your work under a proprietary license? *rips terms of service in half*
>*decompiles your work, neuters it of anti-features, and redistributes the libretized version as a component of other freedom-respecting libre work without your permission*
>oh what's that, you're gonna sue us? lol *brings flamethrower to court*
>*casually murders major proprietary software vendors in cold blood and burgles their laptops*

oh, sorry. didn't mean to post such a serious post on a glowie site.
But for real though, send me that shit.


would have really liked the source code to that


Is this really what Static Analysis is? I've taken a class on static analysis and its all about analyzing OO code for object oriented quality metrics like McCall's model, Chidamber and Kemerer metrics, etc. Maybe it has a different meaning in software/quality engineering from security


Doing posting is peak praxis.


Free software terrorism thank god I wasn't the only one thinking about bricking some corporate servers and giving proprietary vendors free trips to the pit.

This must be incorporated to the agenda of the communist party. The freedom of the working class shall be complete.

Share your custom CSS and JS for bunkerchan settings. Here's mine:


28 posts and 4 image replies omitted. Click reply to view.


/* Firefox */
* {
scrollbar-width: thin;
/* Chrome */
::-webkit-scrollbar {
width: 7px;
height: 7px;

but the settings CSS does not apply to the catalog page, so you would need Stylus extension for that.


Doesn't work


Oh I guess for Chrome you need to set the colors as well. Try this

::-webkit-scrollbar {
width: 7px;
height: 7px;
::-webkit-scrollbar-thumb {
background: #666;
::-webkit-scrollbar-corner {
background: transparent;


Is Firefox just one line? By itself it doesn't seem to do anything.


You need the * {} part too. Maybe try below with color added. It requires FF version 64+ also.

* {
scrollbar-width: thin;
scrollbar-color: #666 transparent;

Hows it not easier in 2020.


Remember, the Oklahoma bombings was possible and now it's nearly impossible to do the same état today.


… anon terrorist attacks happen multiple times a year in most of our countries. the ATF obviously aint shit.

OKlahoma bombings would absolutely be achieved today. Brevik did something similar, there is no reason couldnt do same again in US either theortically. Why do you think otherwise/


You can't simply buy fertilizer and chemicals as a farmer normally anymore. Stealing mining blasting caps is pretty easy still though so I give you that.
You need to be deeply interconnected with the criminal underworld and import explosives abroad.
The ATF had in fact made it harder to do the same as the Oklahoma bombings.


that's just a V1

So there's a small ongoing discussion atm about Guerilla comms in the following thread.
>>>/leftypol/611691 (https://bunkerchan.xyz/leftypol/res/611691.html)

So it brings up the question. In a hypothetical SHTF situation in the continental USA, where Guerillas must operate from clandestine forest bases, and move consistently without an abundant power supply or reliable physical networks, also against an adversary with a very large signals department;
How do we secretly send messages that only an intended recipient, ie Guerilla command or other groups can read?

So one poster suggested a mix of HAM radio types, with modification to allow for encryption, and another suggested LoRaWAN gateways like pest control units or trail cameras use, but with gateways acting as tor servers.
What do you guys think?

Do we have any new guerilla communication threads up?

>LoRaWAN gateways like pest control units or trail cameras use, but with gateways acting as tor servers.

I'm very interested in this, how the hell would it work?

>What about signals analysis? Is there no way that they could hone in on the strength of the signal and have a direct route to your guerilla camp?
I was talking to my friend about this a while back and the idea that he came up with was using pulses from infrared light beams focused on a precise point in order to transmit information. Has anyone heard of anything like this?


Ham radio anon here. You could use something like FreeDV with symmetric crypto and a nonce for every frame. FreeDV works even when you can't hear the signal, down to around -10 dB SNR in a 2.5 kHz bandwidth. This is better than SSB.

Codewords can work just as well as encryption, and works over analog radio (FM, SSB).

You can use APRS for simple data communication and station-to-station chat.

Keep in mind even if you use encryption the feds can easily use HFDF to pinpoint your location. Consider using a remote controlled rig.

Using very large bandwidth can also work to avoid HFDF, since that spreads your signal out enough for it to just look like noise. Something like CDMA and UWB combined.

You can get very large coverage per Watt if you use HF bands like 20m (14 MHz) or 40m (7 MHz).


>So one poster suggested a mix of HAM radio types, with modification to allow for encryption, and another suggested LoRaWAN gateways like pest control units or trail cameras use, but with gateways acting as tor servers.
What do you guys think?
Ideally you would not only try to harden the software, but also optimize the hardware if you can make antennas more directional it will be harder to detect them because they create lower stray EM emission unless you happen to be in-between two actively communicating devices.


The best way to do it is number stations. E.G A type of code that can only be decrypted once and is tossed.



Dealing with one-time pads is a major hassle tho

I did an analysis of the official leftypol twitter performance, and wrote a report on it. You can see more information in these two threads:



I was asked by a poster to also share this here, and to specifically ask if anyone here has any ideas how the twitter cropping algorithm works, and can offer any tips/insights.

Thank you in advance.

I have recently started my first course in Software Engineering. The first programming subject we got apart from C is learning assembly language. I have zero knowledge of the subject and it seems quite intimidating at first glance, and was described to us as a hard course. So I wanted to ask, what would be the best sources of information to learn the language and how to even use it? The YouTube tutorials always seem a bit shit and from my first glance it is true for asm as well. We were also all recommended to read picrel over the course. Is it good and or enough for learning? It's 34 years old, so I was wondering if there were more recent manuals on the subject.

Play TIS-100 or Shenzhen IO or Exapunks. They don't use actually existing assembly languages, but the principles, commands and syntax are kinda similar.


Where would one be able to find a pirated version of this?


I've played all of them on Linux. Can post links to Linux versions if that's your OS, but it shouldn't be hard to find Windows ones via your preferred search engine.


Thanks for the help anons. Just finished my first proper assembly program. Feels good, but damn is this shit unintuitive to code.
