all the people I've seen supporting Palestine and being against the genocide have not changed stance

who have you seen change their opinion ?

What are your strategies to not be late? in c/adhd@lemmy.world

[–] RAM@discuss.tchncs.de 10 points 3 weeks ago* (last edited 3 weeks ago)

I try to be ready to leave, meaning dressed and bag is packed, as early as possible. I am for being as ready as possible at least 15 minutes before I leave. I add and subtract minutes depending on how important the event is and how much I need to have checked before leaving.

also, I try to aim for being at least 10 minutes early for most events. this is working very good for me. it allows small talk with other people who've arrived and it allows time for being late.

it is time consuming, but I've come to enjoy the breaks it gives, before leaving and when arriving early ^^

also, thinking through what I need to prepare before leaving as early as possible. Often, I think about it the afternoon before I have to pack.

good luck :)

//edit:

these systems don't stop me from getting distracted and forgetting things, but because I've moved everything 15 minutes earlier, then when I'm late for my own deadlines, often I'll still make it to the actual deadlines :)

that's a good idea - it certainly would have saved me from a lot of work :)

thanks for the answer :)

I just tried to remove and insert the wifi adapter, and now the dmesg has a message about loading a driver :)

for some reason, it loads the old driver still. rtw_8821cu instead of rtw_8821au. I'm a tad confused, but I'm happy it's working :)

thanks a lot for the help :)

it does not show up from ip link show.

what does it mean, that it is not initialised ?

//EDIT:

I ran a script called remove-driver.sh from the driver that I used to use (https://github.com/morrownr/8821cu-20210916) and now the wifi adapter is up and running again :)

Thanks a lot for the help - I'm not really sure, what was wrong, but I'm very thankful for the help :)

Was the problem, that I had a bad driver installed ?

//Solution:

I installed this driver (https://github.com/morrownr/8821au-20210708).

The driver however, did not work until I ran a script called remove-driver.sh from the driver that I used to use (https://github.com/morrownr/8821cu-20210916). Then the wifi adapter started working again :)

Thanks a lot for the help - I am still not really sure what the problem actually was, but I'm very thankful for having my internet connection back :)

//Original post below:

Hey :)

I've been using a wifi adapter for my computer for about a year. A few days ago, it suddenly stopped working. It no longer shows up when I run 'nmcli device' in the terminal. When running 'lsusb' it still shows up as 'Realtek Semiconductor Corp. 802.11ac NIC'.

To my knowledge I hadn't updated anything before it stopped working. After it had stopped working, I used usb-tethering from my phone to do a system update, hoping it would fix the problem. I think one of the updates was a linux firmware update. Anyways, it didn't fix anything.

The adapter didn't work out of the box. It arrived with a driver called 'RTL88x2BU' and a document stating that it was compatible with the following chip drivers for linux: RTL8811AU RTL8811CU RTL8812BU RTL8814AU

I couldn't get the driver it arrived with to work, so instead I downloaded this driver and have been using it until it stopped working. https://github.com/morrownr/8821cu-20210916

this driver only states that it supports some linux kernel version. I'm using '6.8.0-40-generic', which it does not claim to suppport. I download this driver, which should support my kernel, but it didn̈́'t work either. https://github.com/morrownr/8821au-20210708

I've tried running lsmod on my system, and it seems to be, that no wifi driver even starts. The only thing I can remember doing just prior to my internet not working, was running 'systemctl disable jellyfin.service'. I doubt that has anything to do with this, but I'm not sure what else it could be. My only other theory is, maybe the usb wifi adapter hardware just gave up.

Any help is appreciated ^^

Any good beginner guides for identifying broken parts in a desktop computer ? (discuss.tchncs.de)

submitted 8 months ago* (last edited 8 months ago) by RAM@discuss.tchncs.de to c/askelectronics@discuss.tchncs.de

I've recently bought a used computer, and it has a few problems. I'm looking for a guide to help me identify which parts are causing the problem.

I've tried to watch and read a few guides on how to build a pc, but they haven't given me any information on how to identify broken parts.

I'm interesting in a guide, but I'll also post my specific problems, if any of you know how I might fix them ^^

the problems I'm experiencing are the following:

the screen will sometimes glitch out with black areas when watching movies, but only when in fullscreen. The problem usually disappears for some time when exiting and re-entering fullscreen mode.

The computer won't run certain drivers and sometimes when powering off, the computer will use a long time closing certain applications, but will fail in the end and I have to power it off manually. Also, it will sometimes reset my settings. Back to factory wallpaper and factory everything. it remembers my users and my applications.

I've grouped them into two paragraphs, because I have an idea, that the graphical problem might be caused a bad GPU.

I have no idea, what's causing the stuff in the second paragraph 😅

also, I hope this is the right community for this question - I couldn't find any communities specifically for computers.

any help is welcomed ^^

//EDIT:

Thanks for the help :))

I removed the gpu and now only use the integrated graphics in the cpu, and the visual glitches are gone :))

I've run some tests on the computer (from the boot screen), and it seems the memory is fine. The only driver I know to be a problem is the driver for my WiFi usb. I'll try to work on that, or maybe I'll buy a WiFi card and pray that works better ^^

thanks for the help :))

//EDIT2:

All my problems are fixed now ^^

the wallpaper change was because I am a doofus and forgot that I had made a new user on the computer, which of course had the default wallpaper 😅

the driver problem was only with my WiFi adapter, and I fixed that by removing the current driver (rtl8812ub) and installing another driver (rtl8811au), which fixed the problem :))

thanks for the help :))

2024 = 2³ + 3³ + 4³ + 5³ + 6³ + 7³ + 8³ + 9³ (discuss.tchncs.de)

I just saw somebody on mastodon share this fact, and I wanted to share it here too :))

It can be explained by the follow:

2025 = 2024 + 1

2025 = 45²

45 = 1 + 2 + ... + 9

(1 + ... + n)² = 1³ + ... + n³

and since 1³ is just one, we get the above equation for 2024 :))

This also means that next year will be even nicer, as it will include the 1³ :))

Do you have any other interesting facts about 2024 ? :))

The best name I've found for the last formula is just "Sum of consecutive cubes". I had never heard about that relation before, it really is bizare how math is connected sometimes :))
