Now that I got out of vim, any ideas whether the keys are fixable? How would one attempt a repair? Should I just but a replacement keyboard?#diy #repair

@matthew T440S, a new keyboard with backlight is already enroute (hopefully). At least I have a backup to experiment with.

#JustAdminThingsMy #Letsencrypt certificates auto-renewed (yay!) but did not propagate correctly to #Prosody (XMPP server), and #Slidge (Whatsapp-to-XMPP bridge) silently lost connection, meaning that I missed on roughly a week of family chat, only thinking "what a boring time of year".I'll have to rethink this Rube Goldberg machine of message delivery.

@alrs I had to, manually, yes. For some reason my post-cert-update hook did not work. Have to improve logging.

I have a new keyboard on my #Thinkpad #T440sTurns out the replacement is super easy, barely an inconvenience, and I *did not* need to open the bottom of the laptop at all:https://www.ifixit.com/Guide/Lenovo+Thinkpad+T440s+Keyboard+Replacement/116749And I finally can use Escape again! 🎉

Now that I the Thinkpad community's attention, is there a way to "upgrade" the screen on this laptop?My TN-looking screen has terrible colors and ghosting - I go to the toilet and when I come back, any high contrast image is burned to the screen for the next few minutes...Even a basic 1080p IPS would be an upgrade...

I was building the Adafruit 3D printed case for my #RaspberryPi 4 + HQ Camera.https://www.printables.com/model/32718-raspberry-pi-hq-camera-caseI only have M3 and M2 standoffs / screws. It turns out the Pi uses M2.5 (!?!) - the M3s are too thick, and my M2s are too short.Since I only need it to roughly hold together and not "rattle", needle and thread to the rescue!

The main gripe I have with #Lua is not the 1-indexing, not the non-"mainstream falsiness", not the "weird" definition of table/array length, not the keyword-based lexical blocks, not the global-by-default...But the fact that relational operators are not as virtualizable as e.g. arithmetic operators, forcing bool output. [1][2]This prevents from implementing fancy operators like vector masks in Panda or relations in Z3.[1] https://www.lua.org/pil/13.2.html[2] http://lua-users.org/wiki/LuaVirtualization

@fuxoft Yes. Case in point:$ echo 'c=a+b' | luac -l -GETGLOBAL 0 -2 ; aGETGLOBAL 1 -3 ; bADD 0 0 1SETGLOBAL 0 -1 ; cWhatever the ADD returns is set to 'c'.$ echo 'c=a<b' | luac -l -GETGLOBAL 0 -2 ; aGETGLOBAL 1 -3 ; bLT 1 0 1JMP 1 ; to 6LOADBOOL 0 0 16: LOADBOOL 0 1 0SETGLOBAL 0 -1 ; cThe '<' creates LT/JMP/LOADBOOL instructions, effectively forcing bool output.

I'm trying to upgrade the screen on my #Thinkpad T440s. I'm following this guide: https://www.ifixit.com/Guide/Lenovo+Thinkpad+T440s+Display+(Full-HD+no+touch)+Replacement/63644The guide did not mention one crucial detail - that the screen background is glued to the back, and I just ruined my old screen.Now there's no way back...

Mission successful, I ended up following step 10 of a different guide to get the laptop running: https://www.ifixit.com/Guide/Lenovo+Thinkpad+T440s+Display+Assembly+Replacement/130373#s255250As usually, it's a matter of making sure to "(actually) turn it off and on again".

I think I'm pretty happy with the result of replacing the TN screen on my #Thinkpad T440s to "B140HAN01.1 1NV140FHM-N41 N140HCE-EAA 14'' Lcd screen For Lenovo L440 T440S T440P T450 T450S IPS 1920x1080 HD Laptop LCD Screen FHD IPS 45NTSC, 14.0INCH":- More consistent backlight- More vivid colors- Better color rendering at low brightness- No more ghosting after a static high-contrast screen for ~5 minI can keep my laptop at 10% brightness and it looks fine, my battery will appreciate that.

I wanted to "properly" power my #raspberrypi 5 from 12V. Initially I wanted to go through GPIO pins with a buck converter, but then I thought "what runs on 12V? Car!" So I got a cheapish car lighter plug -> USB-C PD adapter.It's tiny! It claims 35W, the Pi pulls ~10W at peak, so hopefully it's fine. Right now it's powering the Pi via bunch of aligator clip cables, I'm benchmarking it and it hasn't yet complained about undervoltage.Fingers crossed!

$ uptime ... up 3 days, 19:51 ...Seems to be working well for just a bunch of aligator clips hanging off random surfaces!
