I bought a framework laptop because my previous one was so cheaply constructed that it literally disintegrated from use.

I quite like it. I'm not going to pretend that buying a product will solve any systemic capitalist evils like ending e-waste or granting a right to repair, but on a personal level, I'm hopeful to be able to avoid some common pitfalls with consumer products like disposability and planned obsolescence by being able to repair this thing myself or replace parts on it. Plus it seems pretty sturdily constructed in the first place. The keyboard's very crisp by laptop standards and is backlit (which is thoroughly unremarkable, but my previous laptop wasn't, because I lived in the stone age), the trackpad's nice, the screen is annoyingly glossy, though it is high resolution with a large color gamut. Hopefully they release a matte screen at some point. And being able to choose where the ports are on it is a bit of a godsend to deal with cable mess.

Thoughts on this thing?

Also framework's planning to make some sort of marketplace to buy/sell secondhand parts, so you can buy used parts or sell parts to users once you're done with them to recoup some of their cost.

They're also trying to cultivate a market of third-party manufacturers to make parts and modules etc. and they're releasing the specs of their designs accordingly. Maybe it will make the laptop more flexible and less prone to vendor lock-in.

Also they said in the forums they had plans to support coreboot, which is cool.

Why does Rust get hate here? I know its a memed language but is there any good reason not to use it other than be contrarian?

I don't think the language used in the implementation of the compiler has ANY impact on the language it compiles. The language design (usually) is done before even a lexer is written

 No.11073

>>11058
It does influence how the language is compiled, its internal data structures and its function primitives. But more importantly if, we return to the example of fasm, it would only need to interact with code compiled from C during runtime, yet the lowest level of high level programming would still gravitate towards C-like patterns, because widespread modern hardware is for all intends and purposes "built to run C", meaning imperative code with variables of wordsize or below and continuos memory access, thanks to the bottleneck of read/write operations through a memory bus. http://www.loper-os.org/?p=46
Optimizing for hardware reifies its bias towards this programming pattern, even more so with POSIX compatible software. I programmed in C, so I cannot unsee.

 No.11667

Rust gets hate because a lot of its userbase is basically zoomer train stations, furries, etc hyperliberal types that'll remind you to say "person" instead of man or woman. But it's a better C++ otherwise.

 No.11668

>>11073
The processor world moved on from C, now compilers do black magic to turn "imperative code with variables of wordsize or below" into SIMD code. If you want to write it by hand, all the architectures have nonstandard extensions to C to enable vectorization, but they are very clumsy and very obviously don't fit into C's model. A language that lets you easily write portable vector code could become really big.

>>11668
How does SIMD fundamentally change the dominant programming paradigms of C?
As far as I see, it simply amounts to loading data into the SIMD registers, potentially at a size different from wordsize, which could be implemented by loop unrolling of continuous memory access in the form of duff's device.
You may consider how high of a performance gain multimedia processing, the main motivation for adding SIMD extensions to x86, receives from caching, which indicates its proximity to the continuous memory access pattern.
>The high cache hit rates of multimedia applications can be contributed to the following three factors. Most multimedia applications apply block partitioning algorithms to the input data, and work on small blocks of data that easily fit into the cache. Secondly, within these blocks, there is significant data reuse as well as spatial locality. The third reason is that a large number of references generated by multimedia applications are to their internal data structures, which are relatively small and can also easily fit into reasonably-sized caches.

Why is it so hard for chans to be profitable and make money compared to other kinds of "social media" ? is it just the edginess? Or lack of data mining that comes with anonymity?

First forget existing forms like image boards and social media exist.
Now think about this starting from profitability, and work backwards.
You want to maximize the rent you can extract from advertisers.

1. Must be image or video based, so that ads can blend in with the other visual content.
2. Norms to funnel people to create content most similar to ads. Videos should be around the same length as an ad, so everything blends together and can't be re-separated.
3. Must be algorithmically moderated so you don't need to pay any workers.
4. Must have strong identities for two reasons.
- Minor reason: Increase the quality of targeting metrics
- Major reason: So brands can go down and mingle with the plebs. Force people to interact with brands using the same tools they interact with people (Likes and retweets).
5. Captive audience. You want people who have already had their autonomy constrained by circumstance, in this case platform. (Tech illiterates use phones and can't install adblockers to fight back).
6. Platform level data harvesting. Adverting companies want to see reports on where their money went, even if it's 100% a bullshit fantasy (Which it is). The more plausible deniability embedded in the system, the longer the system will operate without tearing itself apart.

Well done, you've invented instagram or tiktok. And not 4chan. Even reddit is clearly showing its age, and fails to be the most modern and extractive social media it could be.

 No.11718

>>11717
1. Chans require an OP which have images or videos (usually)
2. It's totally possible in theory, though not usually done, to have threads/posts which are the equivalent of "sponsored tweets" aka ads which look like normal tweets.
3. Even FB/Insta have manual moderation to some degree. Paying workers, esp. thirdoids to delete spam is way cheaper than making muh deep learning facial recognition spam deleter (tm) latte sipping silicon valley engineers that you have to pay $300k a year.
4. you're right, chans will never have this. It's inimical to the nature of chans. Even with accounts there's limited knowledge of the actual person. Pseudonymous platforms like twitter/reddit are much less profitable than insta/fb which have data mining up the wazoo.
5. Phonefagging is actively discouraged on chans by lack of official apps and also bad mobile CSS. Android has 4chanx at least. This could be corrected though by having mobile friendly CSS.
6. see 5

Your argument basically boils down to platforms which collect the most info and data mine the hardest are the most profitable

ok whatever the point is with the ability to host imageboards cheaply you would think they'd manage to make it work. I read somewhere hosting 4chan costs $20k a month. This is BS. for 4 app servers? Even with the beefiest servers and a load balancer any retard can create a chan for like a few hundred bucks a month MAX. Even bunkerchan at its peak only cost like $120 a month. With shit like that you'd THINK they'd be able to make SOME money on it. At most it should be like 1000 or 2000 dollars a month

Why are 90% of the threads here dedicated to programming? Code has hardly changed since the early 1900s with most of the actual development in computer tech being in processing power and multipurpose functions but computers like that are use by the government for research in medical shit, heavy machinery(rockets, military and exploration tech, nuclear equipment etc that kinda shit) and particle physics than whatever the fuck most people on here are posting about. What's the appeal in the never ending barrage of different languages and shitty undergrad textbooks?

Parcimonie-like[1] RSS feeder. Which means each feed is fetched at a random interval through a throwaway Tor circuit, the goal is defense against profiling you on the basis of your feed selection. Its requests have the exact same fingerprint as Tor Browser at the safest security level. Also supports custom plugins so that you can convert whatever page you want into a RSS feed in case the page doesn't provide its own feed.

(But you still need a separate RSS client to view the fetched feeds locally, like newsboat[2] for example.)

I have a few projects open sourced

- A Rust EPP library for domain registrars
- A browser for git repositories on Gemini written in Rust. It allows you to browse trees but it needs a commit browser to be added.
- A Capistrano-like deployment automation project that's written in shell script so there are minimal dependencies. It allows you to deploy to docker hosts, registries and kubernetes clusters also. I like Capistrano but I didn't want my non-Ruby projects to have a Ruby dependency. It's been working well in production use doing 30+ deployments a day without issue.

I won't link the repos here because prefer to maintain (pseudo?) anonymity, but you can easily find them since there aren't really many EPP libraries for Rust available apart from mine.

Nah for gentoo for sure. I mean, gentoo is in some aspects slower than Arch and others. For example, PGO flag was borked for firefox for many years (I think it works now but idk) and all other distros like Arch have Firefox with PGO compiled and that's 6-10% performance improvement according to mozilla. There are some other packages that also have borked PGO right this second (and compiled with PGO in all binary distros) so basically yeah, gentoo is a meme. Or that is to say, maybe they should stop supporting 100 architectures and focus on relevant ones.

"dark net intelligence" firm aka glowing grifting company wrote an article about chans on TOR.

>An imageboard is considered a type of bulletin-board-like forum that revolves around the posting of images, often alongside text and discussion. Imageboards are characterized by a community of users with non-identifiable usernames, usually simply “Anonymous” - that rely on a system of tripcodes instead of registration with credentials. A tripcode is the hashed result of a unique password that allows one's identity to be recognized without storing any data about the user and entering a particular password will let one "sign" one's posts, often necessary for moderators and staff, with the tripcode generated from that password. 4chan and 8chan (or 8kun) implemented secure tripcodes that are not reproducible across different imageboards and are more resistant to the hashed password getting hacked or cracked. The originating IP address of the user is known to the administrator of the imageboard, but the pseudo-anonymity of the forum structure led to its users calling themselves “anons.”

Since US tech embargo on China is still in effect and US plans to squeeze Chinese tech companies by restricting their access to computer chips. China's reaction to this was to make one of their goals to have a home-grown alternative for Intel, AMD, TSMC and the like to decrease dependence on the US. So I was wondering what kind of progress have they been making lately and what are their prospects of ever having a viable alternative to Intel and AMD?

There is all this talk about SMIC, Loongson and Zhaoxin and that in early 2020 Zhaoxin allegedly published a chip comparable to 2017 level intel and AMD tech and they are planning to have parity with Intel in a few years. Then there are Some sources are saying that China is failing horribly at acquiring manufacturing tech for more advanced processors. And I really can't make any real sense out of it.

So when will I be able to buy a computer that uses a hardware that dunks on burger made tech and sends my personal data to Beijing instead of Washington, if ever?

Hello tech! Recently I have been feeling a bit nostalgic as of late and I am looking to build a computer with the best specs I can put in it that will still be reasonable and run windows 98 for nostalgia and classic computer gaming purposes. The only issue I am having trouble with is where, exactly, to start. I was around during this time, but, I was not exactly very tech savvy. I am curious if anyone would have any ideas for how this build should go. What case should I use? Hard drive? Floppy drive? Etc etc.

Would enjoy to get this off the ground. I think it would be a neat project. If you have any advice let me know. Thanks, tech.
