This is what computers looked like in 1492-1932 (over the span of 440 years total, this is what people had to use before electricity became common).

nah smartphones have been around for a long time and they still give them out at the county fair and stuff.


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.
>In the west calculators are given away for free as promotions.
I only ever won a pen and a mug at some school event.


I didn't mean at school, business just give them away. I probably have half a dozen free calcs. We never used calculators in school until hs and graphing calculators and shit because they're haram for low level math.

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?


It's been around for ages.


Good to know. It appears to be a surprisingly comprehensive archive of some 8chan boards like /hgg/.


In my "software engineering" job, during the past 6 months, I wrote approximately ZERO lines of code.

This is true, however you can probably get around it by just open sourcing your work, with Apache or GPL licenses. Your work will still own it, but the source will remain open, and apparently Apache protects it from patent fuckery or something.


That's nothing. I worked several years in a plywood factory watching the drying machine for problems. Only ever had to press the emergency stop button four times, that was all the work I ever did. No relevant education btw.


I have been in a similar situation and it was a rather soul crushing experience. you don't have anything to do, but it is still work so you can't really engage in non-trivial entertainment
I don't know how people cope with those workplaces where, on the one hand, everyone snitches on you and you have to install corporate spyware, but on the other, there is no real work to be done

I don't think you can license company property. imo the best strategy is simply not telling them about your side project


I think this how a lot of nominally professional jobs go for people.

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:

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.

>In an interview Thursday with NBC News, Reddit CEO Steve Huffman praised Musk’s aggressive cost-cutting and layoffs at Twitter, and said he had chatted “a handful of times” with Musk on the subject of running an internet platform.

<“Long story short, my takeaway from Twitter and Elon at Twitter is reaffirming that we can build a really good business in this space at our scale,” Huffman said.
>“Now, they’ve taken the dramatic road,” he added, “and I guess I can’t sit here and say that we’re not either, but I think there’s a lot of opportunity here.”


Top Fucking KEK this guy sucking off Elon so hard that he thought that doing the same thing was going to be good for Reddit. Despite the fact that Twitter has been losing money and is a giant echo chamber for far-rightoids as Twitter will finally die.

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

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.

Phones near police reported not recording:
-Microwave weapons that stop electronics would not be it as that is not permanent.
-Backdoors are not responsive

Phones near police don't upload:
Simple Jamming a mobile antenna running on battery with a giant antenna running on generator.

Stopping Internet in local areas:
1. If they stop it, they will also ban HAM radio for civilian use.
2. If they ban HAM radio (send, not receive), than no sense creating a mesh due to arrest risk.

Wide area Internet shutdown:
-They are loyal to money. They have to find a way to make money flow. Wide area shutdowns are only loyal outside of 9 to 5 M-F.


A meshnet would only make sense during a time of war, when laws would be suspended or disregarded anyway.


>If they ban HAM radio (send, not receive), than no sense creating a mesh due to arrest risk.
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

what in the heavens do they mean with this formulation?


It means only retards trust Elon's suckware.


If you install it as an APK instead of through a "store" like F-Droid, you don't get automatic updates.


If you install Signal from the APK on their website, it'll download updates automatically and send you a notification when it's ready to install. Then you just tap on it and hit install on Android's usual app install dialog.


Why not XMPP + OMEMO?


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.


Where am I going to get a KL-7 from?

>the Enigma encryption was not fundamentally flawed
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.

Flood detected; Post discarded.


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)


>The reformulation you did for the first search isn't different enough. Either be more creative or get a thesaurus.
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

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

That's interesting, can you make it give highlighted results?

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.

Linux Distro users are good, because it is open source. I won't lie and say linux is good, but if you like linux, what distros do you use?

I'll start
I use Fedora and Manjaro on my two devices, but the one with Manjaro is mostly because i installed it there 2 years ago, and it hasn't broken down yet. If you're considering using Manjaro just don't, I think arch would be better since it's more stable than manjaro probably

>The kernel is by definition seperate from userspace and usually consists of multiple differently privileged parts internally.
Then I expressed myself incorrectly (or I was incorrect, take your pic). What I should have said is: Windows runs a lot of things in kernel space that Linux runs in user space, e.g. window manager. I assume wm in Windows is explorer.exe.


>Windows runs a lot of things in kernel space that Linux runs in user space, e.g. window manager. I assume wm in Windows is explorer.exe.
No, explorer.exe can in fact be killed and restarted through ctrl+alt+del, which is also started by the user on keypress. Windows has graphic components in its kernel, but i don't know to what extent. X-Windows used to come with drivers that accessed the raw video devices. Now, at least on linux, the lower half of any video driver resides in kernelspace.
The windows base system is as locked-down as it is, because there is a system layer, where software runs in userspace with more privileges than a regular user (see the evocative diagrams in my previous post). In principle it's as if init, getty, dbus, powerd, and X were the only programs running as root.


On your own graph here >>20723 window manager is part of the kernel subsystem.

You are right.
The diagram is a bit misleading, as the component most closely resembling a window manager (DWM) operates in userspace while communicating over a kernel ipc mechanism. The "composition engine" (gdi/win32k) in kernelspace ostensibly does drawing to the screen. Documentation hints at some of it being in userspace before NT 4.

>"composition engine" (gdi/win32k) in kernelspace
This time i got it wrong. The composition engine is entirely in userspace. Only the legacy dgi and low-level DXddi apis are actually in kernel.
