I used to dump video frames to jpg with mplayer, do some wild editing with shell loops calling ImageMagick and dc, then reencode it with mencoder.

Democracy is voting to make decisions, elections have always been oligarchic in nature. You're operating on a misinformed definition of democracy that stems from an Orwellian inversion of meaning peddled by aristocrats in the late 18th century. Aristotle outlines clearly in his Politics that the people who actually invented democracy considered sortition to be democratic while elections have a tendency to select for people who are already in the upper levels of society.

I want to get an old thinkpad, like an x200 and make it into a secure, tor-only machine. What is the best way to do this? Something like Qubes OS or is that just a meme? Looking for solutions for full disc encryption, network card that connects to TOR alone, that kind of stuff.

Thanks.

Holy shit, Google and Apple may have unwittingly just destroyed the highly unethical false-sense-of-security marketing of encrypted-messaging apps to dissidents and whatnot.
For years, many of us here on /g/ who have 200+ IQs and who keep our computer gear in a basement Faraday cage alongside our anti-psychotic medication have been alerting the masses that you can't have a secure encrypted-messaging app on an endpoint device that's Swiss cheese. We've been talking about exotic baseband attacks, OTA SIM attacks, 0days against software running on the AP, etc.
But if the latest reports about auto-installed COVID apps in some states are true and not Qoomer-tier nonsense, Google and Apple are perfectly happy to give governments the keys to the kingdom for installing whatever the fuck they wish on a device. Poof go any assurances that dissidents have with regard to their encrypted-messaging apps.
Keep an eye on this. Shit is about to get lit in the neurodiverse community.

Those companies always could install apps whenever unless measures are taken to remove the preinstalled shit from stock devices, so it should not be a surprise that it is potentially used for the COVID tracker business. And there are a lot of allegedly secure encrypted message apps that are glow in the dark honeypots, so even besides the PUP installation shit, problems are already existent about security. Just don't use modern phones, if one has to do shady work or so.

What programming languages do you guys use? I'm mostly Python, Java, C#, C++. Used to like functional programming but IMO now that regular OO languages have alot of function features like first class functions its not as big a deal to write code in a pure functional language like lisp or haskell, better to write regular python or something and occasionally write some functional-styled code

>>9387
Rust has a very politically-inclined community full of wokies who are susceptible to trendy politics and zeitgeist, which as we have seen, corps exploit regularly.

Its development and future is also heavily influenced by Mozilla, and the compiler is free of FSF ideology, unlike GCC.

I actually really like Rust, from a technical standpoint, but there is no doubt that it is far more prone to corporate and political influence compared to C.
>>

 No.9397

>>9387
Also, Rust already has an OS project called RedoxOS, so maybe Rustfags need to leave Linux alone and go contribute there. It is MIT licensed though, so it's basically just ripe for any corporation to swoop in and lock up behind a closed license if it ever develops significantly beyond the hobbyist stage. I don't think it will ever attract a large number of contributors due to the license.

I couldn't give a fuck about le SJWs. Linux is already full of contributions from GPL-hostile companies and that didn't change anything.
You can compile Linux with clang, but you can't compile rust with GCC and the based motherfuckers at FSF already recognized this trick and are working on their own GPL compiler. Let's hope they succeed.

How does anyone use the APP? I have tried to use that app over and over again and i just can't get adjusted to it.
This isn't a knock on the devs or the hard work they have done or the people who use it. It has done a lot of good and with out the app we very well wpuld have probably been put on a different time line where the forces pf evil and the bunker won out.

That being said, I just don't get it. Aesthetically the app is very jagged and rough on my eyes. When in comparison to just the normal browser view I still get to pick my themes and the themes look like they do on my desktop machine. There's also just the general browsing experience. The browser allows me to judt browse the board as if i was on my desktop, but, the app just feels counter intuitive to the browsing habits of imageboards i have acquired over the years.

Can some one explain to me?

And I think you can change themes in the settings (although they're not the same as the browser)

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.

>>9353
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.

>>9358
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.
>>

 No.9366

>>9365
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.
