Is using a tiling WM and a well-configured TLP enough to get the most of my battery on Linux?

 No.22525

>>22524
/bin is real on gales, /sbin links to /bin and /usr links to /. Links to the actual commands are copied from a package hierarchy similar to gobolinux stow. If linux had a proper union mount implementation, the package/bin/s could be be mounted to /bin though.

 No.22560

You can also use mdev or mdevd for managing /dev
Alpine Linux supports both and also udev.

>>22494
>Shouldn't Openbox be as good as a tiling WM too?
Yes. But, as far as I know, OpenBox development has stalled. I think IceWM is still being developed (it's very similar WM). There is also JWM.

Consider switching to Wayland. During the early days of Wayland, so much focus was on embedded and low power devices, where X is an absolute train wreck, and Wayland is now undisputed king.
Taking that mentality forward has real advantages for anything battery powered, like a laptop.

/pol/ might be a better fit for you. Something that used to take me 5 seconds now takes me 20 minutes because I have to go back to doing it manually. Your "solution" was plainly obvious to me before you offered it. And there was nothing "male" about it. I was doing it for years before remove.bg showed up. They went back to not allowing me to copy the image btw.

Is randomizing your MAC address with software like macchanger or NetworkManager enough to actually conceal it or can your hardware MAC actually get leaked when connecting to a random network by whatever means, like wireless traffic sniffing i.e. Aircrack?

Basically, how do I make sure I can't get identified when connecting to random wifi spots or even when only scanning for networks? I know your hostname can also be detected in a LAN but changing that is easier.

If you're going to change the hostname under X remember to update the authentication cookie with xauth or you will break your session unless you restart.

where should i start with linux? i really want to jump ship, but i've been on windows since 2000/xp and really don't know were to start. i want to be able to customize my desktop gui, use video editing software (it's for work), and still play my video games. i've been looking into Nobara and it seem like a good place to start. Should I dual boot it on my main OS, or put it on my old labtop to get use to it?

Virtualbox often breaks after new releases or kernel upgrades, leading to relatively frequent crashes and file corruption.
Apparently Oracle only keeps vbox around as a legacy enterprise product and for gullible hobbyists, so stability and testing have suffered over the last decade.

 No.22505

>>22504
I think you are right to some extent. But I know for a fact of many irl important uses of VMs in corpos and academia that are not legacy or hobbyism at all. Particularly to do with cybersec and other networking related stuff where without a VM you would have to run like 80 physical machines with the same OS and other software on top of each of them and VMs are just a whole lot easier

 No.22506

>>22505
I never claimed anything about VMs in general, only that Oracle treats virtualbox as a legacy and hobbyist product.
IIRC virtualization is indispensible in the server market; Xen, Bhyve and Docker in particular.

That's the list of toggles for disabling telemetry in Firefox. By default, Firefox sends pings every time you shut down your browser, make a new profile, it pings their servers when you run firefox and much more. Is this supposed to be 'le privacy browser?

I actually just copied and pasted one of these hardened configs and starting up firefox still pings home every time. Very cool!

I always get a full sized keyboard. You don't actually need a mechanical keyboard as long as you buy something that's better than the cheap entry-level stuff. That being said, I think Cherry Mx Brown keys are the most comfortable ones.

The actual topics to cover will largely depend on what you want to get out of it. Since you mentioned ASCII, I assume you are interested in the actual representations used by computers and not just the numeral systems in mathematics. I'm sure there are plenty of textbooks that cover these things but I can't recommend any because I learned these stuff by attending lectures in university.

I would cover at least these topics:
- Boolean algebra, maybe a little digital circuits
- Numeral systems (binary, octal, decimal, hexadecimal)
- Bitwise operations
- Number representations (BCD, sign-magnitude, one's complement, two's complement, floating point)
- Memory, endianness
- Arbitrary precision numbers (maybe?)
- Character encodings (ASCII, ISO/IEC 8859, Unicode)
- Maybe some simple image format like something from netpbm? Or some other example of how other things are represented in computers. 3D models, audio? idk

I'm sure I missed something, hopefully other anons will insult me for it,

"current text generation models carry with them the seeds for worldwide human extinction and we need to act accordingly" is a massively strong claim that is entirely hypothetical and carries zero evidence to back it up. It was more believable to say that nuclear weapons would cause a human extinction event and it still didn't happen. Why does anyone take these clowns seriously
