today's helldivers 2 discovery: it has an unlockable revolver. makes sense, right? lots of games do.

you fire six out of six shots and reload. your character uses a speedloader. makes sense!

you fire two shots and reload.

  • if you're in a fight, your character uses a speedloader, and you lose four
  • if you're not, they reload it round by round, and you lose none

this is an incredible level of attention to detail holy shit. nobody does this!!

@whitequark BF4 does some minimal version of this - I think it tracks one step in the middle (e.g. is the mag in but not loaded yet) for some weapons, but that is legitimately impressive

Okay so installing bluefin in a VM to test drive it as a post-nixos desktop. First observation, is installation meant to be very slow? Or have I configured this VM hilariously wrong somehow? With 16 cores and 16G RAM it's been crunching through the installer very slowly indeed, when I was hoping for one of those systemd cinematic universe things where you can dd a disk image onto the disk, reboot and then systemd expands and makes filesystems and stuff and you're done?...

nroach44,
@nroach44@mastodon.social avatar

@danderson the only thing I can think of is that the installer is single threaded, or your vCPU config is a bit unusual and the OS doesn't know how to use it? I've seen libvirt throw 16 sockets at a VM, and naturally the windows desktop VM wasn't having a bar of it.

Swapping it to cores and threads made the difference

Question for my peeps:

My A475 has the touchpad/touchpoint device on the PS/2 bus, and whenever the battery dies, my touchpad is no longer recognized in Linux - ANY Linux.

How do I wake up the PS/2 bus in Linux and get my touchpad back?

The only remedy thus far has been to boot to a Windows install ISO.

@RockyC try adding "i8042.reset" to the Linux cmdline

@textfiles I have about 80 GiB of recorded Japanese TV from a DVR (ads included). Do you know anywhere good to upload it?

It's all MPEG2 so compression probably wouldn't hurt

I guess that if you have a Canon bj-10 or an apple portable stylewriter (Same thing) you need to replace the caps and maybe the battery

Another leaky cap but on other part of the board
Another very crusty cap
A battery, kinda like the ones used on some game cartridges

@kiwa you need to do ALL caps, mine has some damage on inner layers that I've yet to fix from those big bastards

Anyone know what the little cloth loops you put around a socketed fuse to ease its eventual removal are called? Or where to get them?

Not seeing anything obvious under fuse accessories on Digikey. Feels like the kind of thing you can find a thousand of for a dollar at aliexpress if you know what they're called.

nroach44,
@nroach44@mastodon.social avatar

@azonenberg are you talking about something like a pull cord, like some devices have for batteries? Otherwise not sure I've ever seen something like that

So it turns out that capacitor WAS holding a charge!

Always discharge your mains caps everyone!

This was a PlayStation 2 power supply, which I would have thought was modern enough to not need it!

Upgrading this raspberry pi to bookworm has been one of the worst Linux upgrades I've done yet other than the fact that it still, miraculously somehow, booted. Apparently, the bookworm keys weren't trusted by buster and somehow it "upgraded" a bunch of stuff to armhpf (32-bit) instead of arm64, resulting in some not fun broken dependencies. It was quite the foot-shoot over all.

nroach44,
@nroach44@mastodon.social avatar

@vwbusguy Have you done it on real Debian before? s/oldrelease/newrelease/ on /etc/apt/sources.list and update, upgrade, reboot, done.

I've gone iirc 6 -> 7 -> 8 -> 9 -> 10 in one afternoon because my brain figured (and was mostly right) it was easier than burning a disk.

The cURL vuln only impacts these versions of these distros:
Debian 10 (with back ports)
Debian 11+
Ubuntu 22.04+
RHEL 9

So no huge immediate panic for most clients (sad lol)

I'm generally not a fan of AI but one thing I'd really like that seems like it wouldn't be impossible for a machine learning system to do...
give it a compressed file and an uncompressed file. Generate an algorithm to get from one to another

@foone I have a certain piece of Japanese hardware with full disk encryption, community's found what the key is, cracked the software on it, but not the algo in the chip that does it. Same sort of thing I'd love to "throw" something at and leave it for a while

Guys, some hardware (or rather, advice). My burst into smoke 🔥 and now it's okay 😮

🧱 So, I had this problem where my laptop went completely unresponsive: no charging, no powering on, no indicator lights, nothing

🔌 Tried a new power adapter + opened up and line-tested the power socket but no response

🔥 Decided to connect up and try once more. Battery + other indicators finally came on...and also a mini explosion with smoke! So I quickly disconnected

@badrihippo Nicely figured out!

Since that's a decoupling cap, if you carefully snip it off or desolder it, it might work fine.
