I'm going to take a wild guess that you live somewhere that doesn't freeze. lol!

Kudos to you. Where we live, it's cold AF.

When my wife bought a new Mazda, the dealer made her sign a form that said the remote start app would only be free for one year. He told her it was just boiler plate; the remote start app would be free forever. I knew when she bought the vehicle the remote start app would be a monthly charge starting in precisely one year. lol!

I slightly regret switching one of my development machines from Manjaro to EndeavourOS. At the time, I needed to test an app I was writing with ffmpeg v8.0 and Manjaro was not going to have that for quite some time. I tried the AUR package but it didn't work and I had to back it out.

EndeavourOS is absolutely great. I literally am not aware of a single flaw in it. My regret, infinitesimal as it is, is based on being so close to upstream projects. I would far, far rather have a stabilized distro.

My Manjaro machine, for example, has a perfect KDE right now. My EndeavourOS requires directory renaming 2 to 4 times to get it to stick. I know that's not EndeavourOS. It's KDE but I vastly prefer a distro with some quality control.

Meanwhile, Manjaro turned into a dumpster fire so there's no point going back. I do have one machine on Manjaro and it's running fine, taking the extremely occasional update. I may go to Fedora LXQt spin but EndeavourOS is great, except for the Dolphin issue. They may have fixed it by now but I'm too scared to take any updates in case it gets worse.

No problem. I'm drifting away from flatpak, anyway. Anything that's married to systemd is going to be a problem for an increasing number of people, over time.

 

I have a service menu with 13 items that is unsorted.

18 months ago, it was sorted alphabetically. Now I cannot see any sort order for the same service menu.

It isn't in Actions= order, either.

If there is a way to sort a service menu, it would be extremely helpful.

Any help appreciated.

I wish that were true but 99% of the time, it's executives first, then shareholders. Executives give themselves massive bonuses, even when companies are losing money. They don't need shareholder approval, just the board of directors who rarely represent the shareholders or are even the top shareholders.

Reddit used to be a really nice thing with good conversations and good people. That's all gone but I can't help but think every community will go toxic, at some point. Sooner or later, any group of people is taken over by people who either don't understand how to respect people or actively seek to abuse people who do not share their view. Perhaps Lemmy will go that way, one day. I hope not but I will enjoy Lemmy while it's a terrific place.

I understand it's an odd request. I'm testing an OpenCV app I'm working on and want to be able to match the perspective as close to identical as possible as part of some testing. It only took a couple of minutes, after learning how to adjust window opacity.

[–] TomB19@lemmy.world 1 points 11 months ago

Thank you. I appreciate it.

[–] TomB19@lemmy.world 2 points 11 months ago

This is absolutely brilliant. Thank you! This is massively helpful.

The app I want to be transparent is a GTK app: OrcaSlicer. I want to overlay an Orca render on top of a web cam image of the actual part and align them to have identical zoom, perspective, etc. Is there a way?

Any help or suggestions appreciated!

The problem seems to be lack of ability to give the board a magic serial number. The vial app looks for a specific string in the serial number ("vial:") to identify a vial capable keyboard. My R75 won't accept a serial number, no matter what I do.

Apparently, this is a limitation of some cheap USB controllers (always answer 0 to all serial requests). I don't know if that's true but ChatGPT tells me it's so.

udevadm info -a -n /dev/hidraw$(ls /dev/hidraw* | tail -1 | tr -dc '0-9') | grep -i serial  2 ✘ ATTRS{serial}=="00000000000000000000000000000000" ATTRS{serial}=="0000:09:00.0"

Apparently, the magic number can be coded into the UID, also. I'm working on that, too, with no success so far. Apparently, USB controllers don't stand in for UID in any case.

I'm struggling with this. If anyone has some ideas or clear direction, I would consider it a favor. If I can manage to make it work, I'll publish the firmware for everyone.

Even if someone got the mossbed firmware to work, that would be helpful to know. I have been banging on it for three days with no luck. This is the most expensive, cheap keyboard I've ever purchased. lol!

 

My R75 works fine under via.

I'm using the R75 vial firmware located here.

https://github.com/mossbed/r75

It won't compile, as cloned. It's more than just the directory structure which is completely silly. It's not surprising it didn't work, given it's messy state. I had to modify it a bit, so it could easily be something I did.

I had to add a UID:

config.h -> #define VIAL_KEYBOARD_UID { }

and uncomment tap_dance_action in keymap.c.

tap_dance_action_t tap_dance_actions[] = { [TD_RESET] = ACTION_TAP_DANCE_FN(safe_reset), [TD_CLEAR] = ACTION_TAP_DANCE_FN(safe_clear), [TD_CTL_TG] = ACTION_TAP_DANCE_LAYER_TOGGLE(KC_RCTL, _CTL_LYR) };

That's about it.

It compiles and downloads cleanly. Via continues to work but Vial does not discover it.

This mosbed firmware extension claims to be a derivative of this work but it doesn't seem to be.

https://github.com/irfanjmdn/r65/tree/vialrgb?tab=readme-ov-file#guide

Anyone have Vial working? It's a popular keyboard so I expect someone has solved this problem. If no one responds, I'll take it on in a week or so so we can all enjoy ou R75 on linux with Vial.

[–] TomB19@lemmy.world 1 points 1 year ago

Thanks. He has the core done. It could have saved me some time. I'm quite a bit further along with auto discovery and a couple of minor conveniences.

If I can get it to install with a UDEV rule so it runs at user privilege level, it'll be all set and I'll push it into the AUR.

[–] TomB19@lemmy.world 2 points 1 year ago

Thank you. I really appreciate it, on both counts!

 

Like a lot of Chinese devices, my TEMPer clone creates two HID interfaces. This isn't how TEMPer is supposed to work but this unit is a knock-off. It was purchsed from Amazon and I tried to get an authentic part (Got from Amazon. The brand looked right and it wasn't the cheapest TEMPer, by far, but turned out to be a junky knock-off).

Right now, the app only works with root permission. I need to get it completely into the user space

Anyway, it creates two HIDRAW dev interfaces. The first one does not work. It responds on the second one. It always seems to show up on /dev/hidraw3 but I understand this cannot be counted on after re-plug, reboot, or other installs.

How can I create a udev rule that will allow my app to find the device (either scan with HIDAPI or libusb) and create symlink under /dev with user space access that my app can interface with?

Or, perhaps there is a better way?

I'm trying to write a driver that anyone can use with a knock-off TEMPer.

I could use a sanity check on a cooling situation. It doesn't seem right or possible. Sorry for the long post.

CPU: AMD 9700X MB: Asus TUF Gaming B650E Wifi RAM: 4x16GB T-Force CL30 Case: Antec P182 (Giant quiet gaming case from 2007)

The system has been together for about 5 months. When I got the components, I picked up a $30 CAD generic cooler:

"iCan 6-Heatpipe CPU Cooler | 2*120mm PWM Fans with Rainbow Color | TDP - 265W | Fan Speed upto 1800RPM | Fan Noise - 31DBA"

It all ran OK, was quiet but not silent. Only has fan noise when working hard. In other words: Great.

I'm doing a bunch of ffmpeg/x265 transcode benchmarking. With the iCan cooler, it would thermal throttle (75C throttle, 76C measured) at 5350MHz. It would bounce between about 5200 and 5450.

Anyway, a buddy told me the Noctua D15 is the best air cooler going. I did some reading. He seems to be right. It is a highly regarded cooler.

The D15 fits into the system fine but only one of the 140MM fans will fit. The 140mm fan won't fit in the back, due to the VRMs. The 140mm fan won't fit in the front, due to RAM. So, the D15 has a 140mm stock fan and a 120mm screamer (140CFM). That's a lot of air.

It doesn't cool nearly as well. Not even close. I've bumped up the thermal throttle to 80C (where it sits 100% of the time while transcoding). Fans are set to 100%, all the time. It barely makes 5GHz with the D15. Average is about 4900MHz.

I put the iCan cooler back on and it went back to almost boost clock frequency.

The thermal paste is very well done. I was super careful between cooler changes and I clean the old stuff with alcohol before applying fresh and mounting another cooler.

Why does the smaller cooler with a far worse machined CPU contact area cool better than the gigantic D15?

I will say, when using QFan and the iCan cooler, the fans ramp in about 2 seconds after launching ffmpeg. QFan with the D15, it takes about 4~5 seconds for the fans to fully ramp. The D15 has a substantially heavier CPU block and this does seem to add considerable inertia (which is nice).

Any thoughts?
