The M6117C also isn’t the original and not that old. Also the 8MB of RAM aren’t true to the original.

I’m not sure. I occasionally use emulation. And I think it’s fine. Unless you’re a speed runner and need everything to be exact to the frame timing, you won’t notice. Certainly not for a desktop UI like the Win 3.11 on the photo. I guess it depends on the use-case.

Something like a FPGA or an ESP32 can also be repaired, replaced, programmed and most of the things a CPU or different architecture can do. And if the emulation layer doesn’t have too many flaws, it’ll be pretty realistic. Not exactly the same thing, but I think it’ll do for practically any use-case. And it comes with other benefits.

I think you’re allowed to do it just for the sake of it. But I often see people using an original SNES because “emulation is shit” and then they proceed to connect it to the TV set in their livingroom, which isn’t even close to the original experience because it adds lots of latency and doesn’t have interlacing and the colors are different than on a CRT, too. I think that’s just having strong opinions despite being uneducated. And I think I’m equally as well off with my Raspberry Pi and Emulationstation. (Which can also run DOS games.)

In the end everyone is entitled to their opinion. But this also isn’t the original (You can get an old Laptop… I have one with an 486.) But this isn’t the original but a replica. And it’s debatable (in my opinion) whether it’s the CPU architecture that does the realism, or other factors. I think for realism, you’d need a black and white liquid crystal display, a NiMH battery that degrades fast if you don’t charge it right and half the amount of RAM at most. And maybe just a floppy drive. The CPU is something you wouldn’t notice with the current state of technology.

h3ndrik , (edited )

Agreed. I think most prominently competitive gaming; development where you need to assure it later on actually works as intended on the target platform; and business stuff where parties are obliged by contract to guarantee something works flawlessly and keeps running that way - are good examples.

That laptop doesn’t look to me like it was intended to do any of that, so that’s maybe why I’m being a bit negative here. It’s cool and a nice idea, though…

(And we already have ARM-based retro machines, FPGA clones if popular processors available. So there is no need for them to do the exact same thing.)

Is Conduit (Matrix server) sustainable, do some of you host it?

I plan to host Conduit for my friends and family. Even if I invite absolutely everyone there would be no more than 50 users, max. But would it actually sustain and work, as it is not yet on 1.0 is a question. I do not want to host Synapse as I had bad time with it’s (lack of) garbage collecting. We do not plan to join very big...

h3ndrik ,

I installed it like 2 weeks ago. As of now it’s still running and has a really low memory footprint compared to Synapse. But a lot of things aren’t implemented. Chatting works fine. I get a lot of warning messages about not implemented things, though. Like my client (FluffyChat) trying to query some profile status … I’d say try it. I’ve done so. But I can really only give some good advise after a few more weeks of using it. Maybe there is a dealbreaker.

h3ndrik , (edited )

Definitely the whole server name. Other servers and clients can’t guess that information. I think it’s properly documented how to do it.

h3ndrik ,

Depends a bit on how much images and videos get shared. If its mainly used for chat by a bunch of people and a few gifs and stickers in-between, it shouldn’t consume that much storage. But sure if you frequently share all your vacation photos, the cache is going to grow fast.

h3ndrik ,

Ah, well I only read the official documentation on docs.conduit.rs

I’m gonna take a look at this later.

h3ndrik ,

I found that. Seems it mainly addresses caching and database performance, adds some admin and moderation commands. I’m not sure if it addresses any of the shortcomings I have.

My main question is: Which one is going to be maintained in the years to come and have the latest features implemented? And secondly: Why a fork? Why don’t they contribute their fixes upstream to Conduit?

h3ndrik ,

Oh well, seems both reasonable. Maybe I should switch before the projects diverge too much. Conduwuit seems pretty active. Hope it stays that way.

Do you happen to have a link where I can read the backstory myself? Thanks for the info anyways. Seems to be a good call.

h3ndrik , (edited )

Ah, nice. Alright. Thanks again. I’ll see how I can do it. Unfortunately I’ve already set everything up, joined Rooms and connected a few bridges. I hope it doesn’t break. I’ll do a backup first. Seems reasonable and not that hard to upgrade.

h3ndrik ,

Nice, didn’t know about HomeBox. Are there other good inventory systems for home use?

A supermarket trip may soon look different, thanks to electronic shelf labels (www.npr.org)

Grocery store prices are changing faster than ever before — literally. This month, Walmart became the latest retailer to announce it’s replacing the price stickers in its aisles with electronic shelf labels. The new labels allow employees to change prices as often as every ten seconds....

h3ndrik ,

They’re already widely adopted in supermarkets here (Germany).

h3ndrik , (edited )

Seems the two German supermarket chains really like to have the same infrastructure everywhere. Everywhere I go the Aldis look exactly the same. They have slightly different products depending on the country. But the price tags, interior, … is basically the same. Okay and we don’t have “Flaschenpfand” everywhere… (deposit on the plastic bottles and the machines where you can return bottles.) I bet all of this makes it a lot easier for their techs and management. And it could also explain why they sometimes redo a store that still looks fine and fit it with the latest shenanigans.

And as an aside: I’ve shopped in the first Aldi store ever. It’s not far from where I live.

"Moderation tools are nonexistent on here. It also eats up storage like crazy [...] The software is downright frustrating to work with" - Can any other instance admins relate to this?

After a year online the free speech-focused instance ‘Burggit’ is shutting down. Among other motivations, the admins point to grievances with the Lemmy software as one of the main reasons for shutting down the instance. In a first post asking about migrating to Sharkey, one of the admins states:...

h3ndrik , (edited )

Though Lemmy has funding for full-time developers.

And it’s not like other features get implemented in the meantime. Progress is really slow here, even compared to hobby projects.

Edit: Lol, thanks for downvoting.

h3ndrik , (edited )

AFAIK the NLnet funding is still running and there were still some milestones to claim as I last asked them in some AMA. Should be paying them an additional 3.000€ a month?!

They really should be more transparent an link that stuff and their progress.

lemmy.ml/post/11023519

codimd.tyhou12.xyz/s/TukD_H96z#

h3ndrik , (edited )

I’m not sure about the numbers but it should be like 6,600€ a month?! join-lemmy.org shows 3,656€ per month from donations, plus ~750€ a week they said in their last AMA from the NLnet fund.

I’m not sure if I’d consider that low… Sure it’s not much compared to the revenue of a commercial platform. But still, you can build something with like 2x40h weeks. (plus a community)

Maybe they already factored in the 3k from NLnet and it’s just 3.6k in total, I don’t really know. But they’re always talking about two full-time developers plus one more they’d like to pay… So that makes me think it’s probably 6.5k€. Maybe someone can fact-check it.

h3ndrik , (edited )

Since I’m dabbling in AI at the moment: What about llama.cpp? Dude handles like 50 pull requests a week, coordinates everything and codes himself. And it’s really complicated stuff and not the only project. And I mean there is lots of Linux software I use, (web-development) frameworks, smarthome stuff and electronics projects that I participate in and I’m always fascinated by their pace and how they manage to do that in addition to a day-job?! And they regularly push new features… I’ve had contact with some, filed bugreports and sometimes the next day they solved my issues and pushed a new version.

With Lemmy, my UI bugreports from a year ago are still open and not fixed. And it feels like contributions and bugreports are more a burden to the devs here and not that welcome like I’m used to from other projects. And yeah, I’m glad the last release was a bit bigger. But I mean it took 5 months… And moderation tools are traditionally an issue here. I’m glad something gets implemented. But we’re still far from where we need to be. Same with the image handling and proxying.

I’m not sure what to make of this. Sure, software development ain’t easy. But every new release I check the changelog and usually it’s just some minor bugfixes. And twice a year a bigger release like this month with new features, yet the last bigger user-facing feature I can remember was instance blocking in december. And this is more or less adding the ability to hide posts and change how voting is displayed, if you’re just a user.

Edit: I appreciate the work, though. And I like the idea of the platform. It’s just that I’d like it to grow and flourish. But to me it seems we’re often taking baby steps. And in the meantime stuff breaks and admins complain they barely cope with everything with the tools they have.

h3ndrik ,

Kinda depends on productivity. I’d say 45k to 60k€ is alright for an average coding job in some company. I don’t know the details here. For self-employed people that varies a lot and developing Lemmy propapbly doesn’t compare to a salaried job at all.

h3ndrik , (edited )

Thanks. So the number on join-lemmy.org already includes the NLnet fund? I suppose that means you get ~600€ a month from the other (independent) supporters?

I’m confused. Liberapay 1.679$ + Patreon 1.165€ + OpenCollective 935$ + Crypo

adds up to the ~3.600€ but in which category are the NLnet bank transfers?

h3ndrik ,

I think it’s a bit of a chicken and egg problem if the revenue depends on the product. Lemmy needs to be shiny, grow and be attractive to attract more money. And they need more money to do it. Currently the userbase is stagnant at a bit less than 50k active users. I’m not sure if the community will jump in and provide the required amount of money if the situation stays as is.

h3ndrik ,

That makes more sense. Thanks.

h3ndrik , (edited )

Yeah, you’re not doing it right. On Github you have to click on “Insights”. And alike Lemmy which is split into two parts, llama.cpp also has a backend called ggml that does the (tensor) maths. Combined, the git stats are as following for the last four weeks:

  • Lemmy (+UI) 207 files changed, +7,841 additions and -6,472 deletions
  • llama.cpp (+ggml) 707 files changed, +157,754 additions and -95,611 deletions.

So they definitely touch a lot more code regularly. Whichever PRs you clicked on, they added 50 times as much new lines of code in the same timeframe. And coding things like that is maths heavy and you also need to read the scientific papers and implement the maths. And they did quite some maths themselves and contributed their quanitzation techniques and benchmarked and studied them in addition to the coding. I’m really impressed by the guy. And he seems nice and attracted quite some contributors with his excellent and fast software. Reviews and comments their ideas and integrates them fast. And now it’s a flourishing project that leads in its field. And the project isn’t even that old…

I get it. Software development isn’t that easy. Especially the ‘touching different parts of the code’ is something I don’t really like. I mean it is like it is. And having architectural patterns like this is fairly common (logic, database, UI) and you have like 2 models of the data, one for federation and then the internal representation. I’m not that familiar with the Rust frameworks and how cumbersome it is to deal with them. With the correct database abstraction toolkit and other frameworks it gets better and you can often tie the stuff together. Also helps with the bugs. If it’s really bad, maybe the architecture isn’t optimal. Or the chosen frameworks suck. Other than that it’s the job of a programmer to tie those aspects together, deal with the complexity and combine it into a working product.

I’m not even sure if you can assure that Lemmy has no bugs… I mean unit tests, integration tests and reviews won’t cut it with distributed or federated software, right? I mean you’d need to roll out a small cloud of instances and do end to end tests, check if everything federates and if there are performance regressions… I’m not sure where Lemmy is regarding this. I occasionally observe when something big happens like federation breaking.

Sure. And UI programming is also something that is not really fun to me. I’m also not sure why it hasn’t more contributors. Maybe the atmosphere isn’t that welcoming to new people. Or the userbase in total is just too small. I mean fediverse observer reports like 50k Lemmy users, and that’s not that much people if we’re talking about the subset of people who learned programming and have the spare time to contribute. Maybe it’s too interlinked with the rest of the code or not documented enough. I’d say it’s probably not that attractive to get involved because it’s mainly small bugfixes that can be implemented without also getting involved with the rest of the project. And apart from drive-by pull requests, people usually have some bigger vision when they join a project.

h3ndrik , (edited )

Hmmh. Why ActivityPub? I mean I suppose it’s alright as a standard for some turn based or slow trading game. But it’s neither very efficient nor suited for realtime. And having long (and descriptive) JSON messages, queues, … is baked in per design.

And it’s not even interesting to a Mastodon user if player x sold y latinum to player z. So for lots of game logic we don’t need messages in a common format that’s federated to Mastodon, Lemmy, Peertube etc.

I think a nice and not too complicated coding challenge would be to design a world that spans multiple servers. Players could roam a world, go through some door or portal and the client seamlessly connects to the next server. So that part of the world (the other server instance) is behind that portal. That’d make sense from an in-game perspective and won’t be that hard to implement. Basically it’s just like any other game, just that the client auto-connects to servers with some internal logic and not just in the start menu. And ideally authentication would be federated. The new server could ask the player’s home instance to authenticate them on entering the new instance.

h3ndrik ,

How is divorce a matter of consent?

h3ndrik ,

You could also try the ROCm fork of KoboldCpp

Koboldcpp bundles an interface ontop of llamacpp. And generally it’s relatively easy to get it running.

h3ndrik ,

We probably need one super popular self-hosting solution. With SSO so it’s simple to invite friends. Atomic / A/B updates so it’s indistructible. Backups preconfigured and a Marketplace with 1-click installers. Backed by a non-profit or nice community and non-commercial.

h3ndrik ,

And cosmos-cloud.io too.

I think you mentioned the major ones. I don’t think I’d give any of them perfect score. But I’ve had a look at most of them. And I’ve been using YunoHost for years.

I’d really like to have something that I can recommend to people, without any downsides. Maybe for small businesses, too. Or non-profits / clubs etc who need a mailinglist and a Nextcloud.

Is it safe to open a forgejo git ssh port in my router?

Hello all! Yesterday I started hosting forgejo, and in order to clone repos outside my home network through ssh://, I seem to need to open a port for it in my router. Is that safe to do? I can’t use a vpn because I am sharing this with a friend. Here’s a sample docker compose file:...

h3ndrik , (edited )

As of now all advice here is kinda missing the point or wrong… (Exept the one recommendation to do updates ;-) I wouldn’t use Cloudflare as it’s really bad for freedom, watches your traffic and most interesting things aren’t even in the free/cheap plans… You can’t restrict connections to the “Established state” or you can’t ever connect to your server… And SSH is a safe protocol. Just depends on the strength of your passwords… And yeah, opening ports is never 100% safe. Neither is using computers. They can be hacked but that’s not helping… And I’d agree using Wireguard or Tailscale would help. But you already said you don’t want a VPN…

I didn’t have a proper look at the Forgejo Docker container. I’d say it’s safe. It’s probably using keys instead of passwords(?!) I hope they configured it properly if they ship it per default. And it’s running sandboxed in your Docker container anyways and not running a system shell on the machine.

The issue with SSH is, there are lots of bots scanning the internet for SSH servers and testing passwords all day. Your server will be subject to a constant stream of brute-forcing attempts. Unless you take some precautions. Usually that’s done by blocking attackers after some amount of failed login attempts. This is either preconfigured in your Docker container (you should check, or watch the logs.) Or you’d need to use something like fail2ban on top. Or ignore the additional load and have all your users use good passwords.

(What I do is use Git over https. That worked out of the box while ssh would have required additional work. But I also have lots of other ports forwarded to several services on my home-server. Including ssh. No VPN, no Cloudflare … I have fail2ban and safe passwords. I’m happy with that.)

h3ndrik , (edited )

You mentioned exactly the two ROMs I’m currently using. GrapheneOS on my Pixel phone. And LineageOS for microG on my Samsung tablet. I’m really happy with both of them.

I don’t use that many proprietary tech so there is little issues for me. My car only has regular old plain bluetooth, so I wouldn’t know. And instead of some add-on firewall/dns adblocker solutions, I’m just using the Librewolf Mull browser with the uBlock plugin.

h3ndrik ,

Hmm, if you have a home network anyways… Maybe you can run AdGuard/PiHole there. I’ve switched to blocky.

I made it listen externally and just configure it in the network settings of my devices to override the automatic DNS server. That way I don’t need to install sth like AdAway on all of my laptops and phones, because I have one central instance.

Is there anything else that blocks video ads? I’ve never found anything except for uBlock which actually works. And I’ve recently learned that you can enable developer mode in Firefox based browsers on Android and install all the Plugins they don’t like you to use on mobile. Like SponsorBlock etc.

h3ndrik ,

I think you’re doing it wrong. There are lots of people on Mastodon.

h3ndrik , (edited )

It depends on the exact specs of your old laptop. Especially the amount of RAM and VRAM on the graphics card. It’s probably not enough to run any reasonably smart LLM aside from maybe Microsoft’s small “phi” model.

So unless it’s a gaming machine and has 6GB+ of VRAM, the graphics card will probably not help at all. Without, it’s going to be slow. I recommend projects that are based on llama.cpp or use it as a backend, for that kind of computers. It’s the best/fastest way to do inference on slow computers and CPUs.

Furthermore you could use online-services or rent a cloud computer with a beefy graphics card by the hour (or minute.)

h3ndrik ,

Meh. No Flatpak, no worries. And no updates, no new software or security patches.

h3ndrik , (edited )

I have Debian on my servers for a decade or so, and on several workstations. My past experience doesn’t quite reflect that. The Debian guys and gals have always been pretty quick with patching the vulnerabilities. Like outstanding fast.

There is some merit to the bugfixing. But that’s kind of the point of Debian Stable(?!) Like in the meme picture of this post I don’t want updates each day. And I also don’t want the software on my servers to change too much on their own. I know my bugs and have already dealt with them and I’m happy that it now works seamlessly for 6 months or so…

And that’s also why I have Debian Testing on my computer. That gives me sort of an unofficial rolling distro. With lots of updates and bugfixes. I mean in the end you can’t have no updates and lots of updates at the same time. It’s either - or. And we can choose depending on the use-case. (I think the blame is on the admin if they choose a wrong tool for a task.)

h3ndrik , (edited )

Wow. That settles the discussion pretty quickly…

I’m not sure with the transition layer… Isn’t there things like qemu and box64… And multiarch support is part of most of the Linux distributions as of today? I always thought it’s just a few commands to make your system execute foreign binaries. I mean I’ve only ever tried cross-compiling for arm and running 32bit games on amd64 architecture so I don’t know that much. In the end I don’t use that much proprietary software, so it’s not really any issue for me. >99% of Linux software I use is available for ARM. But I can see how that’d be an issue for a gamer, regardless of the operating system being Windows or Linux or MacOS.

And I’m not really interested in the AI coprocessor itself. The real question for me is: Can it do LLM inference as fast as a M2/M3 Macbook? For that it’d need RAM that’s connected via a wide bus. And then there’s the question what does a machine with 64GB of RAM cost. That’s the major drawback with a Macbook because they get super expensive if you want a decent amount of RAM.

h3ndrik , (edited )

Hmmh. I can’t really make an informed statement. I can’t fathom qemu being experimental. That’s like a 20 year old project and used by lots of people. I’m not sure. And I’ve yet to try Box64.

I looked it up. The Snapdragin X Elite “Supports up to 64GB LPDDR5, with 136 GB/s memory bandwidth” while the Apple M2/M3 have anywhere from 100 GB/s memory bandwith to 150/300 or 400. (800 in the Ultra). And a graphics card has like ~300 to ~1000GB/s)

(Of course that’s only relevant for running large language models.)

h3ndrik , (edited )

Maybe you can find a guide/tutorial on how to set it up?

Usually you need the correct packages installed on your system to enable something like VAAPI or QSV. Then you need a version of ffmpeg with that enabled. And then configure it in Jellyfin correctly.

I don’t have any specific insights on how to do it with Fedora. I suppose it’s very similar to how it’s done on other Linux distros.

h3ndrik ,

As far as I know you want a web application firewall to block attacks. A reverse proxy is just to proxy requests and doesn’t necessarily care if it forwards legitimate traffic or attacks.

h3ndrik ,

Just put it on Codeberg or Github. Having other people’s config for reference is always nice. Especially for beginners.

h3ndrik ,

Fair enough. I personally think someday someone will have the same niche issue I’ve already tackled and be happy to stumble over my code while googling it. So I just drop most things I do somewhere for other people to find. Regardless.

But concerning NixOS, I also still need to switch over a few things to agenix and generalize parts of my config before publishing it.

h3ndrik ,

Hmm. There is value in both. When I started out with NixOS I read lots of wiki articles. And we all know there is some room for improvement. And I also read several configs of other people to see how things tie together. And to look up things that aren’t documented. Nowadays I just put in what I’m looking for and “language:nix” into Github. So there’s lots of personal configs that turn up. Sometimes with useful stuff. So I think anything is better than nothing. But obviously if you have kids, prefer them and let other people come up with the detailed wiki articles 😆

Beginner in need of real help!

I’ve been interested in self-hosting for a while, but didn’t really know where to start. I’ve never messed with Linux before and wanted to jump ship from Windows since Microsoft decided to start putting ads everywhere. I came across this post [lemmy.world/post/6542543] which was exactly what I was looking for to start, and...

h3ndrik , (edited )

I’d recommend YunoHost, too. It’s pretty beginner friendly and you’ll probably get some positive results without learning all at once. I mean you have quite something on your plate if you’re learning Linux, Docker, Docker-Compose and maybe networking and Dev-Ops all at the same time.

h3ndrik ,

But actually following Jesus’ teaching would be way too progressive. As far as I remember he was basically a hippie, advocating for love, helping each other out and the poor, and strongly against hate and capitalism. And he didn’t quite like the old traditions. So I think as a christian as of today you definitely need some counterbalance and some other book to point at to defend your conservatism, egoistcal behaviour and hate towards people who aren’t 100% like yourself.

Goodbye secularism, goodbye constitution and whoever still likes what’s been the original idea behind the foundation of the United States of America.

A second-hand used laptop. Or an used Intel NUC.

I’d say it’s difficult to buy anything new for $100 that’s actually worth spending that money.

I’d recommend one if the Mini PCs like

But that’s about twice your budget with a decent amount of RAM and some storage. (And way faster than a RasPi.)

h3ndrik ,

Out of curiosity: Did you measure the idle power consumption?

h3ndrik , (edited )

Hmm. I wasn’t trying to recommend privileged or non-privileged mode, just trying to use that to single in on the actual issue.

Alright, if it’s just av1, maybe try to use a tool like vainfo to find the supported codecs. I think ffmpeg fails if an unsupported codec is explicitly specified. But take care if Encoding is mentioned. Some hardware has decoding capabilities only.

It’s a complicated topic. And it also took me 2 whole evenings to get the permissions and everything right. I’m using systemd-nspawn, so my experience doesn’t directly translate. And it’s not any easier than docker.

For video acceleration I found the Arch wiki somewhat helpful. But it’s lots of info and not specific to Docker. Maybe it helps anyways: wiki.archlinux.org/…/Hardware_video_acceleration
