I'm from yurop and my middle- to high-school was relatively well funded. We had programming classes and you had to pay to go to prom.
It makes you think about where these schools actually spend their money, when we had to order calculators and multiple school books per year. We had some type of consultant to teach us sex ed and he just made us talk about public information videos he played on his laptop.

Zag Forums is an 8chan archive disguised as a forum. It seems no one is posting in it and the site only serves as an advertisement space.
I came across unstructured link farms, fake filesharing sites and autogenerated reviews before, but this type of site seems unique to me if only because of the moderate effort needed to set it up.
Are these types of forums more common than i thought or may this have been an attempt at a type of spam site that never caught on?

For those who don't know, a bunch of major subreddits (at least 3000 in total) are going to go private for 48 hours to protest Reddit killing third party use of its API. It's technically supposed to start tomorrow but a bunch of subreddits are getting a head start already.

More info:

https://www.bbc.com/news/technology-65855608

Thoughts? There's more backlash than I expected, and I'm all for it, but I think going with a 48-hour blackout with no demands is basically a toothless gesture, much like the 24-hour protest strikes some unions do. Doesn't really mean anything.

Hey comrades,

This article came up https://www.vice.com/en/article/v7e9y3/activists-are-designing-mesh-networks-to-deploy-during-civil-unrest about an open source mesh network (including the hardware made from easily accessible parts) to be used when governments shut down the internet. It seems the original project is dead, but I did manage to find this repo
https://0xacab.org/kirsa/mycelium-mesh-old/

I have (as of this moment) limited expertise in hardware and protocol programming but I have time and resources to delve into it and perhaps start it back up.

There's several things they mention in the description of the program, such as a lack of encryption, lack of peer to peer, how all messages are saved in nodes, etc. These strike me as someone with not too much knowhow, as bad design aspects.

I would like to dedicate this thread to trying to dig up more info on this project, and for people with more know how to chime in on what ought to be different, if you would restart as the sole dev(s) anyway, or pointers on where to start.

They don't have the means to enforce a ban on ad-hoc wifi and bluetooth even if they wanted. Imagine how many extremely tech-literate cops they would need running around with PDAs sniffing for packets to triangulate
>A meshnet would only make sense during a time of war
Meshnets are used commonly to share free internet or to connect remote areas without landline infrastructure, some of them are even sponsored by local government

Is this the only safe communications technology out there? To elaborate further, WWII-era encryption methods, such as the German Enigma machine, would not be easily cracked by a modern consumer computer. The Enigma machine was used by the Germans during World War II to encrypt their communications, and it was considered highly secure at the time.

Cracking the Enigma code was a significant challenge and required the efforts of a large team of mathematicians, engineers, and codebreakers at Bletchley Park, including notable figures like Alan Turing. The codebreakers employed various techniques, including developing early computers called "bombes" to assist in the decryption process. It took years of dedicated work to decipher Enigma-encrypted messages.

Modern consumer computers are significantly more powerful than the computing technology available during World War II, but cracking the Enigma code still required advanced mathematical and cryptanalytic techniques. It's important to note that the Enigma encryption was not fundamentally flawed; rather, it was vulnerabilities in the implementation and operator errors that led to its eventual decryption.

However, it's worth mentioning that modern consumer computers, combined with advanced algorithms and techniques, can crack certain encryption methods used during that era if they were weak or based on known vulnerabilities. But the more robust and well-implemented encryption methods, such as the Enigma, would still pose a significant challenge even to modern computing power.

OP the fact that the Enigma never encrypted a letter to itself was a huge flaw. in fact it was what allowed the bombes to work in the first place, thanks to easily guessable cribs (a known-plaintext attack)
I'm not even sure what point you're making. you can implement AES in a microcontroller for offline encryption if you like. it is largely immune to known-plaintext attacks

Name a single time you used a search engine to find anything worthwhile. They are even on a conceptual level just a bad way to navigate the web, and on top of that many algorithms are centred around marketing and spam and noise muddles up every result. They remove the interactive aspect of the web which makes it such a unique medium and help commercialize its very content. Stop using search engines.

Two issues:
a) You're limited to just what the SEARCH ENGINE reddit offers which is limited by it's bias.
If I were interested in getting a torrent of a video game, and reddit is legally or culturally pressured to take down content about that, (just like r/shoplifting and r/incel respectfully), unless I can find a link to a separate resource from another comment, (which also can be censored if reddit is against such resource), I'm fucked.
b) Using reddit limits you to what reddit directly offers. If the solution is something outside of reddit, you'd have to hope that this resources is accessible (either through subreddit link or a comment link)

Like seriously: I recently had an issue with trying to figure out why my cpu jumps in usage when watching a video, and while I found the solution of a clone of a stackoverflow, I would've never found it since I'd neither knew that it was on that alternative stack overflow, but I'd never find a resource that would've granted a SEARCH ENGINE that would give me the stack overflow alternative or even an answer from that overflow.

And it's funny that you go: "normies use it" – normies type "X reddit" on a search engine since even though reddit is helpful, it doesn't always help and having alternatives lined up is needed.

Again: search engines are fine, they're just one of many tools in your tool box to work with.
Saging so the thread can wind down from the dumb take.

Soft of related note, do you guys have any search engiones you recommend?

I switch to duckduckgo in the past, and I'm noticing that they recommend not based off
of what actually will satisfy you query.
Like these two screenshots just happened to me recently – and I haven't has bad of a result than when I was using youtube, and I got only 3 results I kind've wanted, and 9 results that were literally disconected from anything I asking.
On that youtube example. Here's one off the top of my head: trying to look up lets play content to the parrot moment from ace attorney, and after 4 results it game me results from ace attorney role play videos.

I don't know anything about the internal design of search engines. Still i suspect duckduckgo tends to match keywords and literal text while google has more of a dwim approach. Most of the results you are getting are SEO optimized to death. I do several things to minimize the presence of these in the search results:
>minimize pronouns, prepositions and articles as much as possible
<the more individual word matches, the more likely optimized sites will win
>quote the word with the least likely results or an idiom
<may get no results at all, especially with long quoted text
>if a search fails, try again with synonyms
The reformulation you did for the first search isn't different enough. Either be more creative or get a thesaurus.
The most important thing is to anticipate what sites may match. Some search patterns will always give you crap results, even with google or whatever dwim search.

with searx you can curate what websites are pulled from in search results, you could set it up to e.g. search all alt stack overflows you compiled (not a response to you so much as a comment on a practical way to cut down the google bullshit while still finding collective knowledge thats been posted online b4)

Not a bad tip, but it's odd just how many rings you have to jump through to make the engion work with you.

Like sure, these two aren't that different:
>Study in one sitting or throughout the day
>Should you study multiple times a day or once a day.
But I find it odd that a word like "study" was almost entirely descarded, and instead I was given results for tips for studying and working out.

>The most important thing is to anticipate what sites may match. Some search patterns will always give you crap results, even with google or whatever dwim search

Interesting.
You can use the "site:" argument in the search, so I guess I should use more tags.

The apple car development team has to be so demoralised right now. EVs are losing steam thanks to Elon and the increasing conciousness about battery technology, its limitations and the imperial origins of lithium. Even more, the dream of self driving is as far away as it was 10 years ago, for they didn't take in account the crumbling infrastructure of the US (and the whole western world for that matter). And now Tim Cook is betting the future of Apple on "spatial computing", which itself it's an ofshoot of self driving development.
