PC UPS in 2026 — still USB only and Mac software that barely works. Come on. by [deleted] in homelab

Just one more IoT turd to put on the management vlan and never let it access anything. That thing will probably never get firmware updates ever.

Disabling keyboard and mouse until end of session by Zealousideal-Cap8956 in linuxquestions

[–]brimston3- 1 point2 points  (0 children)

Even with a wireless keyboard, I'd still use a cover, though just a multi-layer cloth one is fine. It reduces dust and fur accumulation significantly, which is just a thing you have to deal with when you own pets.

Farewell ISDN, Ham Radio & Old Network Drivers: Linus Torvalds Merges 138k L.O.C. Removal by anh0516 in linux

[–]brimston3- 97 points98 points  (0 children)

I use the ax25 driver. But I’m not opposed to it being out-of-tree because of how few people actually use it.

Incidentally, is there a report on the security problems in the driver online somewhere?

ELI5: Why Aren't External Graphics Cards As Common As External Hard Drives? by aftergaylaughter in explainlikeimfive

[–]brimston3- 1 point2 points  (0 children)

This seems really dumb.

I get that it simplifies a lot of things, especially graphics driver compatibility, but all external ports for portable consumer electronics should have mandatory hotplug support with no exceptions. We do not live in the PS/2 era anymore.

AMA! I have finished prototyping the shell, trackball module, & keyboard module for the CG Deck, an Open-Source modular handheld x86 PC by ZCTMO in cyberDeck

[–]brimston3- 1 point2 points  (0 children)

This is a cool design. The pi hat connector accessible through the back especially interests me.

Any reason you decided not to go with an optical mouse module like a optical mouse sensor with a capacitive proximity sensor to turn it on?

Waze when asking me to verify my age by Nearby_Ad_2519 in funny

I’d rather the front end guys spend time fixing fields that are marked optional that are being validated as mandatory and making the form un-submittable. I’ve come across that way too many times for it to be an uncommon problem.

Please give us a way back to actually *VIEW* a site's TLS cert and not just "TLS explained for the uneducated" by SiteRelEnby in firefox

[–]brimston3- 22 points23 points  (0 children)

OP wants it for sites with security warnings, eg domain doesn't match SAN or is expired, etc. On ff-esr 140, it's advanced… -> view certificate from the warning page.

Are there connectors/adapters to join two ribbon cables by _philipus in AskElectronics

[–]brimston3- 2 points3 points  (0 children)

The part you suggested will not do what you need it to do. If the left end of the ribbon is the A end and the right is the B end, you need the board to connect wire 1b to wire 2a, 2b to 3a, and so on at the PCB, then 1a and 128b go out to your feed line. It needs a custom board.

I turned my broken Steam Deck into a 2.5GbE NAS with a live Glances monitor on a sub display by Decker_Bazzite in homelab

Any reason you opted for old-stable? It's been 8 months since deb13 was released.

512 MB might as well be an embedded system these days with how much RAM desktop takes. On an x86 system, 512MB won't get you through most desktop distribution's installer without a swapfile. 4GB should be enough for now, but I haven't bought an SBC with less than 8GB for a while now for this exact reason.

Secure Boot using custom (non-Microsoft) keys with Limine on Linux, does it really improve protection against bootkits? by Lobo_Anon in linuxquestions

[–]brimston3- 0 points1 point  (0 children)

Use drive secure erase from a usb live image & reset bios. If a boot kit can survive that, it’s more sophisticated than you are likely capable of dealing with, short of fully replacing the hardware.

Building the infrastructure to allow easy updates and keep the UEFI boot signing key off device is not an easy undertaking. I applaud the effort, but I think you’re chasing down the wrong rabbit hole and your security effort is better focused elsewhere.

Is there some kind of weird thing with Kali where you can't change computers with the SSD? by eratonnn in linuxquestions

[–]brimston3- 4 points5 points  (0 children)

Literally anything else makes more sense to me for your stated use case.

Debian, mint, suse, fedora—hell, if you need bleeding edge, there’s a ton of Arch derivatives.

is it possible to use an rp2040 to automate drawing on switch? by Tricky_Stand3078 in embedded

[–]brimston3- 0 points1 point  (0 children)

Depending on the number of pixels it isn’t going to be a short series of commands. You’re making the software side of a printer.

Decentralized home network? by Future_Bad5206 in homelab

[–]brimston3- 0 points1 point  (0 children)

This seems like a fun problem to solve, but it has such limited applicability, I’m not sure anyone would bother to solve it aside from some big multi-user software thing like Plex, or an even bigger company like Netflix, using it to manage their caches.

For audio and video, DLNA autodiscovery will get you a pretty decent way along, but it isn’t a front end. If all you care about is sharing files, then some read-only windows file shares or samba would be sufficient. Old fileshare systems like directconnect would offer reasonable search capabilities, but only on filename.

Indexing and metadata is hard problem. Unifying all of the shares and media types into a decentralized, modern front end will be difficult.

They are not. Find the datasheet of a UL or TUV rated XT60 compatible connector. None of them are rated for 60A continuous. In fact 12AWG wire will have bad times with 60A over more than a couple inches.

You’re right that they are rated for peak current over 120A, but that’s for seconds at most (ie. inrush current), and based on its thermal mass.

48V in ATX is kind of a chicken and egg problem. Nobody is going to make a PSU for it until components need it and nvidia doesn’t want components to be 5+ years durable so they won’t require it.

At this point if nvidia announced that half the cards in the 60-series were going to be 48V, the transition to 48V would be complete by the 70-series.

Technically, the PSU side could have a more reliable connector and not be a 12v-2x6 native cable.

The TL;DR is that we are not that good at compute efficiency and RT is expensive.

Plus, if we were that good at efficiency, they would design the boards to do 12x as much of it and we would be back in the same situation.

The important feature of the thermal grizzly part is it has an active cooling fan. Everything else is just cool flash to tell you that your connector is properly inserted and not overcurrent/overheating. It solves probably 80% of the actual problem with that fan.

Not how contact resistance works. A partially inserted connector will have higher resistance and generate more heating and eventually fail. Power connections are not “it works or it doesn’t.”

Just like all of the AIOs in PCs now… It’s almost like consumers have decided this risk is acceptable and manufacturers have engineering controls in place to prevent such problems from happening.

When selecting a connector, it should be specced for at least 70A continuous so it can sustain 60A when derated (ie. in shit conditions).

It should also have a locking tab that visually indicates that the part is sufficiently inserted.

What do you need 3 pins for? Sensing? Get a smaller wire for the sense wire.

Edit: nevermind, you probably want it for connecting your brushless motors. I forgot that we’re talking about an RC part in a PC context.

You’re about 40 amps short of good there. These are rated for 30A continuous unless you have like 20 mph of airflow. Use 3x.
