Hola, comrade Anon. What Linux distro is on your device? What Desktop environment? If you say Windows or Mac you're getting sent to the gulag for using Liberal Yankee cyber imperialist software.

How do you hold packages from installing certain files on apt or simply stopping them from upgrading? in pacman.conf you can have IgnorePkg, NoUpgrade and NoExtract. As for the differences, they do differ a lot: one has 2 commands with long args that do what other can do with just a short one; other takes commands when the other can do it only after making a change in the config file.
Upgrading everything while leaving no cached packages behind is pacman -Syu && paccache -rk0 but in debian you have to use apt-get update && apt-get dist-upgrade && apt autoremove && apt autoclean. And no don't get me started on the difference between dpkg, apt, apt-get, synaptic and aptitude. This syntax shows clearly that the goal was not to have the pm being used from its CLI interface, rather they probably thought it as a library for clicky-click GUI wrappers that get installed alongside the DE. You could try partialy fixing it with shell aliases, i think that could do wonders but i can't figure out how you could fix the broken configuration. It took me like 15 minutes just to find out how to stop it from pulling 2GB of useless dependencies when installing xorg as there's no mention of it on debian wiki, but how about not interrupting the install just to ask me for what to do with the developer provided config file for a random package? Why is this the default behavior instad of simply keeping it in the cache just like the package itself so i can make that choice later? You can't use the command in a script if it does that. Pipeing yes? i don't think so. Adding user repositories? Another pain in the ass. In the end what pissed me the most was how it's supposed to be noob friendly just like the distro itself, but i always get headaches when something goes wrong with it.

Anyway, pacman isn't the greatest- i didn't said that. That would be apk-tools but with this capabilty i was talking about which it doesn't have at all. I also can't say i couldn't live with apt only, but it would be inconvenient.



if you're asking about portage, its equivalent to that pacman thing is package masks.


But you shoudln't always do what you want, and themes are just a mistake.


Linux Mint (just cos I felt like a change), but normally an OpenBSD.

I'm no certified Linuggs Eggspert, but I've just continuously heard about systemd and how bad it is over the years from all manner of /g/entoomen,
but I still really don't understand it like at all.
I essentially "just wanna grill for god's sake" when it comes to using my computer, so I try to stick in the realm of Linux things that just werk.

So my question is what's so bad about these things in general I guess?
Both for nixlets like myself, as well as for the experts and the whole of Linux?
General discussion thread as well for these things.

> doing one thing and doing it well
t. system where every utility implements its own idiosyncratic way of handling command line arguments


systemd is analogous to a well functioning ML One Party state, and is good


Basically, Linux used to have a bunch of random programs made by random people that did random things that Linux users needed their computers to use.

-need to synchronize network time?
-need to get an IP address?
-need to schedule a program to execute once a week?
-need to write system logs somewhere?

There are random programs written by random people to do all of that, and they were called by shell scripts that executed them in the original Linux init daemons.

What systemd did is, it made a very excellent init daemon that used this trick with sockets that allowed it to start all services at once, making the computer boot really fast.

If it had stopped at that, people would have loved it.

This is a good thread with nice accessible and, amazingly to me at least, relatively simple to follow guides.

I'm not a programmer, I just want to automate some of my job/hobbies, but I just love how cosy this place is for noobs like me reading this stuff.

Thanks for making this shit comprehensible, I took one class once because I thought about doing Game Dev and I was confused to shit and no one would explain. They just expected you to sink or swim. The thick accents didn't help either.


Damn, that takes me back. I think the last I checked they are still running some oldschool phreaking challenges.

I'm honestly up for any brand, I live in Hong Kong (no I don't support the neolibs that is currently getting ) so I could get some mainland brands as well.


I have a Lenovo T450s and its great, Thinkpads have been getting less good as time goes on though
Really depends on how much you want to pay and what you want to run, I'm pretty much stuck on Thinkpads because I hate using trackpads and need the trackpoint but I've looked at Huawei and Xiaomi and some of the higher end Huawei devices are really nice with excellent 3:2 screens and good Linux support

If you're planning to run Linux and spend a fair bit of money on a quality machine System76 do Linux dedicated laptops that are supposed to be pretty good and they come with Coreboot

The Serval WS looks sick. It's basically just a portable desktop.


You have to tell us what you want out of a laptop. Does it have to be powerful, durable, affordable, large, portable, etc…

Laptops are pretty shit these days though, because they are produced more as a fashion accessory than as a tool that needs to be handy and ergonomic.


My intent is to have mostly desk work so a good monitor and RAM is nice. I don't plant to game on it so a dedicated GPU isn't my concern. Budget is &lt550USD


T, W, E or P series thinkpad
Check out /tpg/ on 4chan for specifics, T440p is current reigning thiccboi, socketed upgradeable processor, cheap for the machine you get, good expansion options
T470 should also be doable with your budget but that generally has a 2c/4t ultrabook processor which is fine irl but isn't as nice as a proper quad core

If you don't want a thinkpad a new line of Ryzen mobile processors just came out that are meant to be very good, you could probably get an entry level machine with 4th gen ryzen for that kind of budget, or pick up a higher spec machine 2nd hand

I am having a discussion with my buddy right now about the pros and cons of tiling windows mangers; Why are they superior? Personally with my time spent using i3 I find it incredibly convenient to have all my windows placed and perfectly sized in a way that maximizes my screen real-estate. He says that he can already do that with a normal GUI interface. He also said the keybindings can be confusing, which, ok, I can understand that, but, practice makes perfect in my opinion.

What says you /tech/? Are we Tiling master race here at bunkerchan or not?

the less you have to click and drag shit, the faster you are. rule of thumb for computing.


Some tests showed that l33t keyboard users are on average not faster than n00bs who use a mouse. Instead they perceive the speed-up because it is their mind that does more stuff in the same amount of time, since for every action they have to recall exactly which keys to press - whereas a mouse user barely has to think and instead spends the same amount of time just moving the mouse.
The benefit of using the keyboard is more in reducing physical movement instead of being faster. But that depends on what you're trying to do. Some things are just way easier with a mouse, even if they take a few milliseconds more.


its been almost 2 months since i switched from kubuntu to arch+i3. I couldn't be happier. it took a couple of days to configure, then maybe a week to get used to it. Now, using a floating desktop paradigm seems extremely inefficient to me. don't get me wrong, i don't feel superior because i use a tiling wm, but after i got used to it, it just feels weird having to always reposition windows with the mouse and minimizing/maximizing them.
They do look good, which i do like, but i use it because it's efficient, at least for me. When i tried it, i instantly fell in love with it. the manjaro i3 iso is a good way to get started


Using a floating window manager after a few months of using a tiling window manager is very frustrating. Tiling window managers with good keybinding and window placement are so much supperior but it is hard to explain why. Everyinth just "flows" better, especially with multiple monitors or high resolution display. I personally don't like i3wm much but it is pretty good if you're using the python autotiling script. If i only had one monitor i'd use awesomewm but with multiple monitors i prefer spectrwm, xmonad, and qtile.


I use dwm on Manjaro after switching from i3. I like the suckless philosophy and the way dwm arranges its tiles.

Who's doing lefty tech shit that isn't computer wizardry? 3D printing, open source hardware, electronics, manufacturing, phys sec?

Whatcha making? What are some projects you're into?

I've been prototyping some mischief doodads - 3D printed throwaway handcuff "keys", slingshots and snips for offending valve-stems/zipties - not that 3D printing is all that useful for -the ppl- but after seeing every idiot with a printed hop on the covid ppe train I wonder if freely available low-cost diy projects might help radicalize the hardware folk. Also been doing actually useful shit like leveraging my access to industrial suppliers to get gloves, respirators and googles out to the secret antifa supersoldiers worldwide

If it is a hobby then it belongs in /hobby/ not in /tech/


I mean machinery isn't that inaccessible - "makerspaces" frequently will have some CNC routers now and many metropolitan areas have shops or art collectives where welders, casting, lathes and digital fab tool etc can be accessed with a membership. Hell my local bicycle club has a CNC plasma cutter they built and another friend bought and refurbished a Kuka industrial robot for under a couple grand.

Welding, casting and woodworking can all be individual level investments and you hardly need the anarcho-syndicalist revolution to go in on a a knee-mill with a couple friends. Other than like bicycle stuff or making idk parts for other machines I'm not 100% on what is helpful for ~the revolution~ I would love to hear ideas though - there is a CNC mill languishing in a friend's motorcycle shop and I haven't had the motivation to go try and get it running so I can use it.




Makerspaces took over Hackerspaces and pushed capitalist ideology into what had a sort of revolutionary DIY spirit. I don't really know where I'm going with this in terms of substantial critique, it's just a feeling I've gotten. The same thing like how corporate "Open Source" co-opted and marginalized Free/Libre Software.


Very cool and useful story

What kinds are you thinking because prototyping / low-vol production of PCB stuff is definitely doable. You'd still need to buy components from a conventional supplier (unless you go hard desoldering junk or something) - and most modern devices are all SMD stuff so anything you want to make with your human meat fingers will have to be a lot bulkier.

Ideas for hardware things:

radios are cool I've heard - making antennas and shit

same with mesh networks- idk much about computers other than the one at my house my mom put a couple games on it but it seems like the internet is cool and important and idk yall dual power infrastructure?
https://technical.ly/2015/04/06/12-communities-experimenting-mesh-networks/ kinda old article but I've heard of working projects in metro areas

Maybe like air conditioning/ power generation? I know a lot of low income areas have poor access to this and it can be an actual health issue when combined with comorbid conditions of poverty

I finished getting what I need\want last week. Archived the following conferences in their entirety: CCS, CGO, ICFP, ISCA, ISMM, MICRO, OSDI, PLDI, PLOS, POPL, SDE, SOSP, UIST, VEE.


Anything on there relevant to planning an economy the size of North Korea? (Asking for a friend.)


No, its a computer\technology association… Not that it matters, it will be too late for you to look after today.


>its a computer\technology association
I figured that much from the OP. I don't expect them to have stuff explicitly proposing things for socialism. But if they have stuff on scheduling things in a big company…?


They should have linear programming, (mathematics) optimizations, etc.

check out this guy's youtube channel if you want to see some of the cool shit that's doable in a one-man game project with this engine: https://www.youtube.com/watch?v=EsJa0n-u67c


I second this motion.


>What would interest me (no idea why you'd care about that): I'd like to have a tool for people voting how to share things or tasks, like spliddit.org – but as something you can download and run offline (could be just a HTML file without any pictures and with javascript stuff for client-side computation).

I can build for you for like 30$

Has anyone heard of cwtch.im ? it's made by the same people who made ricochet (which is now deprecated). it's still in the early stages but it looks like some sort of multicast version of ricochet.

Possible replacement for IRC in the future?

Riot is just a client for the matrix protocol though.


Well that's probably what anon means then.
Matrix/Riot is already in the GNU/Linux position it seems in regards to people calling it by the name of the interface rather than the underlying system.


if we're thinking about it this way, Riot is more like GNU than it is like Linux. GNU is what the user actually interacts while Linux does all the mediating with the hardware so that shit actually gets done. So it's more like Riot/Matrix.


It's more like Riot/Electron (or Riot/Firefox). Matrix could be POSIX. Or you could say, Riot is not Matrix.

But it doesn't matter, they are changing their name: https://blog.riot.im/the-world-is-changing/
