I haven't ranted for today, but I figured that I'd post a summary.
A public diary of sorts.. devRant is amazing, it even allows me to post the stuff that I'd otherwise put on a piece of paper and probably discard over time. And with keyboard support at that <3
Today has been a productive day for me. Laptop got restored with a "pacman -Syu" over a Bluetooth mobile data tethering from my phone, said phone got upgraded to an unofficial Android 9 (Pie) thanks to a comment from @undef, etc.
I've also made myself a reliable USB extension cord to be able to extend the 20-30cm USB-A male to USB-C male cord that Huawei delivered with my Nexus 6P. The USB-C to USB-C cord that allows for fast charging is unreliable.. ordered some USB-C plugs for that, in order to make some high power wire with that when they arrive.
So that plug I've made.. USB-A male to USB-A female, in which my short USB-C to USB-A wire can plug in. It's a 1M wire, with 18AWG wire for its power lines and 28AWG wires for its data lines. The 18AWG power lines can carry up to 10A of current, while the 28AWG lines can carry up to 1A. All wires were made into 1M pieces. These resulted in a very low impedance path for all of them, my multimeter measured no more than 200 milliohms across them, though I'll have to verify and finetune that on my oscilloscope with 4-wire measurement.
So the wire was good. Easy too, I just had to look up the pinout and replicate that on the male part.
That's where the rant part comes in.. in fact I've got quite uncomfortable with sentences that don't include at least one swear word at this point. All hail to devRant for allowing me to put them out there without guilt.. it changed my very mind <3
Microshaft WanBLowS.
I've tried to plug my DIY extension cord into it, and plugged my phone and some USB stick into it of which I've completely forgot the filesystem. Windows certainly doesn't support it.. turns out that it was LUKS. More about that later.
Windows returned that it didn't support either of them, due to "malfunctioning at the USB device". So I went ahead and plugged in my phone directly.. works without a problem. Then I went ahead and troubleshooted the wire I've just made with a multimeter, to check for shorts.. none at all.
At that point I suspected that WanBLowS was the issue, so I booted up my (at the time) problematic Arch laptop and did the exact same thing there, testing that USB stick and my phone there by plugging it through the extension wire. Shit just worked like that. The USB stick was a LUKS medium and apparently a clone of my SanDisk rootfs that I'm storing my Arch Linux on my laptop at at the time.. an unfinished migration project (SanDisk is unstable, my other DM sticks are quite stable). The USB stick consumed about 20mA so no big deal for any USB controller. The phone consumed about 500mA (which is standard USB 2.0 so no surprise) and worked fine as well.. although the HP laptop dropped the voltage to ~4.8V like that, unlike 5.1V which is nominal for USB. Still worked without a problem.
So clearly Windows is the problem here, and this provides me one more reason to hate that piece of shit OS. Windows lovers may say that it's an issue with my particular hardware, which maybe it is. I've done the Windows plugging solely through a USB 3.0 hub, which was plugged into a USB 3.0 port on the host. Now USB 3.0 is supposed to be able to carry up to 1A rather than 500mA, so I expect all the components in there to be beefier. I've also tested the hub as part of a review, and it can carry about 1A no problem, although it seems like its supply lines aren't shorted to VCC on the host, like a sensible hub would. Instead I suspect that it's going through the hub's controller.
Regardless, this is clearly a bad design. One of the USB data lines is biased to ~3.3V if memory serves me right, while the other is biased to 300mV. The latter could impose a problem.. but again, the current path was of a very low impedance of 200milliohms at most. Meanwhile the direct connection that omits the ~200ohm extension wire worked just fine. Even 300mV wouldn't degrade significantly over such a resistance. So this is most likely a Windows problem.
That aside, the extension cord works fine in Linux. So I've used that as a charging connection while upgrading my Arch laptop (which as you may know has internet issues at the time) over Bluetooth, through a shared BNEP connection (Bluetooth tethering) from my phone. Mobile data since I didn't set up my WiFi in this new Pie ROM yet. Worked fine, fixed my WiFi. Currently it's back in my network as my fully-fledged development host. So that way I'll be able to work again on @Floydian's LinkHub repository. My laptop's the only one who currently holds the private key for signing commits for git$(rm -rf ~/*)@nixmagic.com, hence why my development has been impeded. My tablet doesn't have them. Guess I'll commit somewhere tomorrow.

Autodesk + Linux is such a goddamn clusterfuck.
Firstly, they only release RPM builds for Maya, and say that they officially support RHEL and CentOS only.
No support for Debian, Arch, etc. What. The. Fuck.
Fine. Okay. Corporate policy. I can live with that. I use alien to convert the RPMs to DEBs on my ZorinOS installation and then found a script which does the installation for me. Cool.
Installs with a few library fuckups. Okay, no problem. I added the missing library versions (ancient libpng and libtiff). I run it. It throws up with some error involving licensing.
Upon searching it seems that Maya 20-fucking-17 can't handle the "new" consistent device naming system (the one which renames eth0 to enp1s0 or whatever). WHAT THE FUCK. Okay. Found a way to disable that. No effect. It's doing the equivalent of a boot loop with the same error.
Wow. This is the leading player in 3D content creation software :/
(As an aside, I did try to install Fedora 28 but it keeps failing with a TPM error. Yay for Linux distro quirks).1 -
Today, I have installed/uninstalled a combination of [windows 7, arch linux, dual-boot] a total of 9 times...
I wouldn't be surprised if my 120G SSD fails next week
It all started when I had to whip up a GUI-wrapped youtube-dl based program for a windows machine.
Thinking a handy GUI python library will get it done in no time, I started right away with the Kivy quick-start page in front of me.
Everything seemed to be going fine, until I decided it would be "wise" to first check if I can run Kivy on said windows machine.
Here I spent what felt like a day (5 hours) trying to install core pip modules for kivy.. only before realizing my innocent cygwin64 setup was the reason everything was failing, and that sys.platform was NOT set to "win32" (a requirement later discovered when unpacking .whl files)
"Okay.. you know what? Fuck........ This."
In a haze of frustration, I decided it was my fault for ever deciding to do Python on windows, and that "none of this would've happened if I were installing pip modules on a Linux terminal"...
I then had the "brilliant" idea of "Why don't I just use Linux, and make windows a virtual machine within, for testing."
And so I spent the next hour getting everything set up correctly for me get back to programming.... And so I did.
But uh... you're doing GUI stuff, right? -> Yeah...
And you uh.. Kivy uses OpenGL on windows, doesn't it? -> Yeah..?
OpenGL... 2.
-> Fuck.
That's when I realized my "brilliant" idea, was actually a really bad prank. Turns out.. I needed a native windows environment with up-to-date non-virtual graphics drivers that supported at least OpenGL2 for Kivy GUI programs!
Something I already had from square 1.
And at this point, it hurts to even sigh knowing I wasted hours just... making... poor decisions, my very first one being cygwin64 as a substitution for windows cmd.
But persistent as any programmer should be in order to succeed, I dragged my sorry ass back to the computer to reinstall windows on the actual hardware... again.
While the windows installer was busy jacking off all over my precious gigabytes (why does it need that much spaaace for a base install??? fuck.). I had "yet another brilliant idea" YABI™
Why not just do a dual-boot? That way, you have the best of both worlds, you do python stuff in Linux, and when it's time to build and test on the target OS, you have a native windows environment!
This synthetic harmony sounded amazing to the desperate, exhausted, shell of a man that I had become after such a back-breaking experience with cygwin
Now that my windows platter with a side of linux was all set-up and ready-to-go, I once again booted up windows to test if Kivy even worked.
And... It did!
And just as I began raising my victory flags, I suddenly realized there was one more thing I had to do, something trivial, should take me "no time" to do, being in a native windows environment and all.................... -.- (sigh)
I had to make sure it compiles to a traditional exe...
Not a biggy, right? Just find one of those py2exe—sounding modules or something, and surprisingly enough, there was indeed a py2exe—sounding module, conveniently named... py2exe.
Not a second thought given, I thought surely this was a good enough way of doing it, just gonna look up the py2exe guide and...
-> 3 hours later + 1 extra coffee
What do you meeeeean "module not found"? Do I need to install more dependencies? Why doesn't it say so in the DAMN guide? Wait I don't? Why are you showing me that error message then????
-------------------------------
No. I'm not doing this.
I shut off my computer and took a long... long.. break.
Only to return sometime the next day and end up making no progress, beating my SSD with more OS installs (sometimes with no obvious reason to do so).
Wondering whether I should give up Kivy itself as it didn't seem compatible with py2exe.. I discovered pyInstaller, which seemed to be the way Kivy wants exe's to be made on windows..
Awesome! I should've looked up how Kivy developers make exe's instead of jumping straight into py2exe land, (I guess "py2exe" just sounded more effective to me then)
More hours pass, and you'd think I'd have eliminated all of my build environment problems by now... but oh, how wrong you'd be...
pyInstaller was failing, and half the solutions I found online were to download some windows update KB32946..whatever...
The other half telling me to downgrade from Python 3.8.1 to Python 3.8.0000.009 (exaggeration! But you get the point)
At the end of all that mess, I decided it wasn't worth some of my lifespan, and that maybe.. just maybe.. it would've been better to create WINDOWS GUI with the mother fuc*ing WINDOWS API.
Alright, step 1: Get Visual Studio..
Step 2: kys
Step 3: kys again.6 -
Yet another day at my company, Im rewriting some old code for client (rewriting old, php 4 system for vindications managment) and you know the moment when you are focused and someone comes to you to absolutely ruin your focus. Fine, whatever. Oh, for fuck sake. Again dev is doing as support becouse one moron with second can't login into zimbra admin panel and add fucking mailbox. I show them exacly how they login, remind them they are admins too, slowly show them, so you click "manage" than you click that gear icon and than you click "new", fill in email address and password. As simple as 1-2-3. Okay, fuck it, time to go for a cig. I just finish up few lines and stand, grab my vape and start walking towards door. In door I find my buddy with 2 random people. He told me that they are interns and that I should show them some basics and stuff around that. Oh god, fuck my life. If anything, Im definitely very bad teacher, mainly becouse I often have problems with saying what I mean in the way that somebody actually understans and knows what I am trying to say. Whatever. Fuck it all. I grab two of our old laptops that nobody used in like a year or so, and first thing I quickly figure out, is that one day for some what the fuck reason I dont even dont bothered to remember I installed Arch on both while I dont usually use Arch. I just needed it for some specific reason. Whatever. So I guess I will need to upgrade fucking system. Our network isn't really great so that was like... hour or so. In the meantime I figured what they know about coding in general etc, and holly shit. One of them (there was boy and girl), girl, apparently never ever in her life even touched code. Well... fuck. Why am I wasting my time? Becouse there was some programme or some shit like that... Someone could tell me before so I could mentally prepare.. fuck it. whatever. So while laptops are doing their pacman thing, I sit with them and slowly start to explain based on my machine some really basic concepts. Second guy actually had some expirience, he knew how to make some really really basic logic and stuff, so he had another world of problems, becouse it was PHP and, as we all know, everyone hates PHP, and... yeah.. You can probably imagine his approach. Yes, you get user input in super global array. I really wanted to say "Now shut the fuck up and write that fucking $_POST".
hour or so passed, I was close to giving up to not let my anger rise (im not really good teacher... I mentioned it. I suck at teaching others) but luckly machines upgraded. He wanted to use visual studio code, she didnt care too much, so I installed phpstorm in trial mode. whatever. Since that's linux and they were not comfortable with that, I walked them through installing LAMP stack, and when finally it started to look like LAMP stack, I requested them to google how to install xdebug, becouse xdebug is very usefull and googling skill is your best weapon on that field. I go for cig, come back and what I see boiled me a little bit. The girl was stuck looking at github page randomly looking through xdebug source code and idk... hoping for miracle (she admited she thought there will be instructions somewhere) and the guy was in good place, xdebug has a place to paste your phpinfo() for custom instructions. But it didn't work for him, he claims that wizzard told him it cant help him.. hmm intresting, you are sure you pasted in phpinfo? yes, he is sure. Okay, show me.
Again mindblown how someone can have problems with reading.
so his phpinfo() looked like that:
```<?php
phpinfo();```
I highlighted on the page the words "output of phpinfo". He somehow didn't see it or something. He didnt know, he thought that he needs to put in phpinfo so he did. OMG.
Finally, I figured out I can workaround my intern problem, and I just briefly shown them php.net, how documentation looks, said to allways google in english, if he uses tutorial to read whole fucking thing, not just some parts of it, and left them with simple task, that took them whole day and at which they ultimately failed.
To make 3 buttons labeled "1" "2" "3" and if someone presses one of them, remember in session that they pressed it and disallow pressing other ones.
Never fucking again interns. Especially those who randomly without apparent reason almost literally just spawn in front of you and here, its your fucking problem now.
Fuck it, I have some time to get back to my stuff. Time is running so lets not waste it.
After around 15 minutes my one of my superiors comes in and asks me if I can go on meeting with him and other superior. My buddy goes with us, and next 3 hours I was basically explaining that you cannot do some things (ie. know XYZ happened without any source of information) in code, and I can't listen for callbacks from ABC becouse it wont send anyc cuz in their fucking brilliant idea ABC can't even know that this script would even exist, not to mention it wants callbacks.
Sometimes I hate my job.4 -
So last night I ran out of space on my root partition, apparently 30GB isn't enough for `/` besides `/home` and `/data` because both `/var` and `/usr` used around 14GB each so I decided to create partitions for them, had 500GB unallocated disk space on my SSD for if I wanted to install windows on my machine besides Arch Linux.
I edited the fstab file and sure enough, the partitions were mounted on boot, everything went fine. Then U realised the data wasn't actually removed from the first partition so I decided to mount the drive again and remove the files, the system still worked fine.
Untill I rebooted. Apparently the bit scripts require files in the`/usr` folder which wasn't mounted at boot, but right after. F*ck, system won't boot and now I'm in a recovery shell in busybox. After googling and reading the arch wiki I noticed a small message saying what you should do if you want to have `/usr` on another partition. I didn't do any of that.
After a couple of hours and a lot of reboots and chroots from a live USB to the broken installation it was fixed without losing any data! I did learn to read the manual or wiki to see any specifics when using more partitions. 😂2 -
A friend of mine who wants to learn about Linux has a stronger will than me, as I think installing Linux in 2020 is gonna break me but he's still stoked as shit. I'm fucking serious. He asked me to install several distros, in order of interest (because they all fucking failed, because of fucking course they did) on a USB HDD he was using just for this.
We tried, in order:
Arch: initramfs wiped his Windows HDD when it crashed. IDFK how, but it zeroed the top 32KB of the drive. It wasn't even the right HDD...
Linux Mint: nvidia drivers refused to see his GPU after install. No matter what we did. Live media saw it fine until it was installed on the external drive, too.
Debian: Installer couldn't see the external HDD, ever. No matter what we did. It had a /dev entry, lsblk and fdisk saw it, I could format and mount it, but the installer crashed when it refreshed the device list when it was present. Every goddamn time.
Fedora: Installer broke halfway through as an executable (or 70) were corrupted, but the disc matched the ISO and the ISO sums correctly, so this is apparently how it was packed and shipped.
CentOS: Refused to boot. Just entirely. GRUB would go to load the kernel and it'd hang.
All ISOs and discs were verified as matching provided sums using MD5 and SHA256. How the fuck is Linux so fucking hard to get working on older hardware in 2020? Worked great in 2008, worked great in 2018, why is 2020 such a goddamn issue?11 -
yes, i know this isn't omg! ubuntu
yes i know it's obviously not StOve (you guys are way too nice)
but im going to look like an idiot for asking this here. my process is a rollercoaster to read so bear with me
context:
· xubuntu 17.10
· zsh (not that it matters)
° i want to be able to use java -jar file.jar
i tried using that command
zsh: java: permission denied
then used sudo
sudo: java: command not found
i grabbed the generic x64 tar.gz and extracted to ~/.local/.app/java/
set the Java path to the openjdk folder inside, no good
i installed openjdk-8-jre
couldnt figure it out that way, so uninstalled
RE-GRABBED the x64 tarball
extracted into /usr/java
set the path to the folder containing java & javaws executables
still no luck
what is the problem here17 -
Linux, you never fail to amaze me!
Started using Arch based Manjaro with xfce de couple of months ago. Everything was mostly fine even though I've never used anything that was based on Arch but it had a learning curve.
Couple of weeks ago I couldn't update my packages, I thought it would fix it by itself but I was wrong as you already probably know.
So yesterday I tried to manually fix it. Famous last words. After a lot of googling, trying some terminal commands - and failing, I see a warning labek on some text on the arch wiki - sudo pacman -Syi --force. I said fuck it and did it. Let's see if it works, I try to install a package, I mistype the name, press backspace - it puts a space instead of deleting?!?!?
I tried restarting, googling - nothing...
Guess I'll switch back to Debian based OSes.5
