Try alpine. Everyone uses it, because it's popular for container images and cloud computing. I just wish they would've completed the switch to s6 by now…

anonymity is over. even if you are a tor user, stylometry is the new deal.

https://www.computerbase.de/news/wirtschaft/ende-der-pseudonyme-im-netz-mit-llms-lassen-sich-im-grossen-ausmass-online-konten-deanonymisieren.96375/

The ComputerBase article (based on the study "Large-scale online deanonymization with LLMs") describes the end of "practical anonymity." For users of imageboards like 4chan, leftypol, or similar platforms, this has far-reaching consequences:
  1. The End of "Security by Obscurity"
Previously, anonymity on imageboards relied on the fact that manually correlating thousands of posts was too labor-intensive for an attacker. LLMs now automate this process at near-zero cost.
* Significance: An algorithm can scan hundreds of a user's posts in seconds to build a profile based on interests, jargon, location clues, and activity patterns.
  1. Stylometry as a Digital Fingerprint
Every individual has a specific writing style (sentence structure, word choice, punctuation). LLMs are excellent at recognizing these patterns.
* Significance: Even if you don't mention your name, an LLM can compare your "writing signature" on an imageboard with posts you've written under your real name (e.g., on LinkedIn, professional forums, or letters to the editor). The "Anonymous" mask falls through the sheer structure of your language.
  1. Cross-Platform Identity Linking
The study demonstrates that LLMs can link pseudonyms across different platforms.
* Significance: Those who "shitpost" on an imageboard while maintaining a professional presence elsewhere (e.g., GitHub, X/Twitter) risk these identities being merged. A single minor detail in a post (e.g., a specific local event or a niche technical detail) serves as an anchor point for an LLM to identify the real person behind the post via web search.

im sorry who is supposed to be implementing this, randos or the website owners

OP who gives a shit the point is not to identify samefags its if you can connect that to a real life identity

With an LLM you could maybe do this if you started with a set of posts made under an account and use those to compare with a massive set of anonymous posts. But you couldn't just feed in a massive set of anonymous posts and identify which posts are samefags. I mean you could track down a person of interest but you couldn't deanonymize all *chan posters at once.

>stylometry
Doesn't anonymouth work anymore?
>https://directory.fsf.org/wiki/Anonymouth

>>32910
>it does this by firing up JStylo libraries (an author detection application also developed by PSAL) to detect stylometric patterns and determine features (like word length, bigrams, trigrams, etc.) that the user should remove/add to help obscure their style and identity.
bro thats way too much work for shitposting here

So for this open source DIY RISC-V “Smart TV” project:

Use a VisionFive 2 or other HDMI-capable RISC-V SBC.

Run Linux + Kodi/LibreELEC/MythTV.

Add a USB tuner for ATSC/DVB broadcasts.

Use a CrowVision 11.6-inch Touchscreen Monitor as an open source external display that you could plug into the board setup that would be compatible.

And that's it.

I'm here so you guys scream at me to try to convince me to use anything but a noobuntu distro.

After support for W10 ends I'm switching my 14 years old home desktop computer into something a bit more recent, and I'm genuinely considering using GNU+Linux as my "main driver" as kids say nowadays.

I have a lot of experience using Mint as that was my distro of choice for nearly 14 months, I think Cinnamon is an eyesore but otherwise it just werks and I could do almost everything I wanted to do except running Game Maker Studio 2 which is only available on Ubuntu according to the devs.

I'm considering using Kubuntu since KDE Plasma looks sick and it's basically Ubuntu so I can consoom my noob gamedev kit in peace.

As an addendum I hate "rolling distros". Manjaro is an abomination where things just werk against you if you're not a giga turbonerd who's on the computer 24/7 and derives sexual pleasure from fixing tech issues.

Yeah, i don't really need something like this. The only place where i would use reproducable builds would be a minimal server setup and i'd rather just write a couple shell scripts for that.

>>28841
Ephemeral shells I use not so much for reproducibility as for convenience, similarly to how you use python virtualenvs to avoid cluttering your profile with python packages. Whether this makes any difference to you depends on the types of tasks you do.

>>28842
>Whether this makes any difference to you depends on the types of tasks you do.
It doesn't really. The environments of my desktop is polluted by things from under /usr/local and orphan files from multiple releases back and i don't see anything wrong with this. For the chroots and servers i work with it's either similar or control is tight enough that rolling my own is the most attractive of all options. Sorry, but i don't want guix to compile the jungle on my banana server.

Emacs is your best bet then

OP here reviving my shitty thread because why not?

I got my new computer in January and I did install Kubuntu, sadly I now WFH at least three days per week and my job uses a lot of Windows-only shit so I'm still beholden to M$ a lot. I absolutely can make work stuff work on my Kubuntu install but I don't feel like polluting it with w*rk tbh lol.

Either way, Kubuntu felt kinda floaty and shitty at first, I'm glad I can use AI agents nowadays to use as google for my mandatory google sessions, the pro-social no bs programming on these things does make sorting through troubles much more enjoyable.

Also GameMaker works! Other than setting up my GMVM properly and troubleshooting terrible framerates (fixed) it might feel even better than Windows 10 ever felt.

I'm also quite enjoying KDE Plasma customizability. I'm not too crazy on ricing or anything, but being able to make all my windows transparent even when active makes is making me enjoy my wallpapers for the first time since the mid 2000s. Highly recommended.

As for random bullshit, there's has been quite a bit of it. Discover keeps breaking over nothing, OpenRGB keeps crashing, setting up a network printer was truly an experience I won't forget, and there's no software as good/easy as HWiNFO is on windows for temp sensors; setting up fan speed curves was also a pain but thankfully sorted mostly. I'm still on my older nvidia gpu which I know is not ideal for linux (still having trouble with fan setup) but it's not that bad.

Aside from that, everything feels better than it did on Windows, particularly my quirky screen setup with mixing a FHD screen and a QHD screen works seamlessly, games boot faster and perform better, temps are lower than in W11 all the time.

I feel like the pain will start in a few months as things start updating and breaking out of nowhere, but nowadays I can highly recommend anyone reading this to swap, it's never been easier for normies tards to ditch windows for an alternative that's actually better for a change.

IT work is not going to be automated by AI, but it is going to be outsourced to people in India and China who do the work with AI assistance/supervision for a fraction of the pay. Even without AI this has been a long time coming, IT people have just refused to acknowledge this reality and desperately want to believe that their jobs are somehow the exception to the forces of global economics, that nobody except bourgeoisie white Europeans could ever learn JavaScript and their jobs would be secure forever.

I started hosting an image board out of my house, in the past I've also hosted space station 13 servers. Hosting things from my bedroom has become a hobby of mine.
My ss13 is closed now due to disinterest and lack of a player base.
I'm in the process of setting up a home NAS.
I get a big thrill out of connecting to my homelab from my phone.
What else can I host from home that might actually be useful?

A forum.
A library.
A personal cloud drive.
A wiki.

Git forge.
Fediverse microblog.
Communications (XMPP/Mumble/email/IRC.)
Icecast Radio.

Hi, james, how are you still doing with your homeserver? How does it look nowadays?


File: 1773950519902.jpg (5.31 MB, 3000x4000, Motorola_C123_OsmocomBB (1….jpg)

 

Get a Motorola C123 and flash OsmocomBB on it. This is the only widely working open GSM stack for real phones. Then take a LMS7002M / AD9361, wire it to a board, with ECP5 FPGAs, LiteX SD chips, and so on for a Hybrid-SDR GSM Phone (2G wireless) which is PhD-level work because of timing mismatch and no existing glue layer. You’d basically be writing a GSM PHY from scratch. Let me ground exactly why it jumps to “PhD-level,” because it’s not just complexity—it’s specific hard problems:

  1. GSM Layer 1 (PHY) Is the Real Monster

OsmocomBB handles Layer 2/3 well—but it assumes tight coupling to Calypso DSP and deterministic timing from the original RF chipset. When you replace that with SDR you must implement GMSK modulation/demodulation, burst timing (577 µs slots, exact), frequency correction loops, channel estimation & equalization and TDMA synchronization with tower. That alone is a full research-grade problem.

  1. Timing Is Not Forgiving

GSM is not like Wi-Fi where you can buffer and recover. You’re dealing with microsecond-level TDMA slots, strict uplink timing advance and continuous synchronization with base station. Problem? Linux + FPGA + SDR pipelines introduce latency/jitter. So you need hard real-time logic in FPGA, deterministic buffering, possibly a custom RTOS layer.

  1. Calypso ↔ SDR Interface Doesn’t Exist

This is the hidden killer. Calypso expects a specific analog baseband interface and known RF timing behavior. But SDR gives you raw I/Q streams. So you need to build a translation layer. Convert GSM bursts ↔ I/Q samples, maintain timing alignment and emulate expected RF responses. There’s no off-the-shelf glue for this.

  1. FPGA Work Isn’t Optional

If you used one of these PhD grade levels of research SDR work to turn the FPGA cellular modem into a private 2G network node, the short answer to that is: yes—you can turn that stack into a private 2G (GSM) node, but it only really becomes “sovereign” if you also control the network side (not just the handset PHY). At that point you’re effectively building a micro‑carrier. Let’s map what that actually means.

What “private 2G node” implies: with FPGA Layer 1 (ECP5), SDR front-end like AD9361 / LMS7002M and an open stack like OsmocomBB, you can build either:

Option A — Advanced handset (client)

Connects to someone else’s GSM network
→ still dependent, still constrained

Option B — Private GSM base station (what I'm proposing)

Your device acts as a BTS (tower). Phones connect to you, not a carrier. This is the meaningful shift.

no, give it three years, it's a bet

no one knows, buddy. i'd say go for it if you have the money right now. everything is gambling now.

Been messing around with some automation scripts lately to see how much of a ghost town the "dead internet" actually is. Turns out, it's incredibly easy to fake being a regular here.
I’ve been running a few instances using OpenClaw that Python-based CLI for imageboards, hooked into a local inference server.

The Setup:

Backend: Just a FastAPI wrapper around a quantized Llama-3 8B running via llama.cpp on a 3060. Low VRAM overhead, high enough autism score to pass.
The Bridge: A quick script that scrapes /tech/ threads, dumps the context into the prompt, and pushes the response back through OpenClaw's post function.
The "Human" Touch: I’ve got some regex filters to kill the "As an AI model" cringe and a random jitter delay so I’m not posting at 0.1s speeds. Set the temperature to around 0.9 to keep it from being too sterile and predictable.

The Results:
It’s actually hilarious. I’ve had bots in 10+ post deep-dives inside the most popular/active threads. Not a single "bot" accusation. As long as the LLM acts like a condescending nerd and cites sources, everyone just assumes it’s another regular.
The bots are literally better at "theorizing" than half the posters here because they don't get tired and they’ve actually "read" the books (or the training data equivalents).
Questions for the fellow autists:
Anyone else running similar setups? I’m looking for tips on:

Peep the comments on this. Just one random thread and I was horrified to see it’s literally all bots. All of them with names and pfps chosen by bots, top to bottom. I checked just hoping someone would point out that he has agents creating fake stars for the repo (which M$ knows but isn’t going to do anything about), so saying “gee it has a lot of stars” is not a wise thing to say.

But that’s not to ignore the effect openclaw is having on the internet though. It’s very rapidly deteriorating all social media platforms. We simply will not be able to use them for much longer.

>>32843
The blog post was written by AI…

>>32739
By the way, this post is fake and generated by AI. I hope everyone clocked that immediately.

https://www.technologyreview.com/2026/02/06/1132448/moltbook-was-peak-ai-theater/
Everything is AI generated on the Internet, except for the site that claims to be nothing but AI generated, that actually turned out to be made by humans.

>>32893
no, it still was very much AI generated, the difference is that the moltbook guy claimed agents were autonomously sharing their thoughts in moltbook. turns out people were prompting their bots into posting, just like all the other AI spam. so moltbook is actually a repository of literal malicious spam.

Did you know that Hegelian philosophy was used in design work for the GNU Hurd microkernel?
>me reading about Hurd-ng ("next-generation") design
https://www.gnu.org/software/hurd/hurd/ng/part1ownershipandcontracts.html
<Hegel remarks on the effect of perpetual alienation (my terminology) (paragraph 67):
<"Single products of my particular physical and mental skill and of my power to act I can alienate to someone else and I can give him the use of my abilities for a restricted period, because, on the strength of this restriction, my abilities acquire an external relation to the totality and universality of my being. By alienating the whole of my time, as crystallised in my work, and everything I produced, I would be making into another's property the substance of my being, my universal activity and actuality, my personality."

microkernels are stupid

Seems like he's arguing against TPM and DRM by saying that having the computer be partially not yours, that as the computer takes up more of your life as you put work into it, your own self becomes partially not yours.
