https://git.kernel.org/…/ke…/... sure some of you are working on the patches already, if you are then lets connect cause, I am an ardent researcher for the same as of now.
So here it goes:
As soon as kernel page table isolation(KPTI) bug will be out of embargo, Whatsapp and FB will be flooded with over-night kernel "shikhuritee" experts who will share shitty advices non-stop.
1. The bug under embargo is a side channel attack, which exploits the fact that Intel chips come with speculative execution without proper isolation between user pages and kernel pages. Therefore, with careful scheduling and timing attack will reveal some information from kernel pages, while the code is running in user mode.
In easy terms, if you have a VPS, another person with VPS on same physical server may read memory being used by your VPS, which will result in unwanted data leakage. To make the matter worse, a malicious JS from innocent looking webpage might be (might be, because JS does not provide language constructs for such fine grained control; atleast none that I know as of now) able to read kernel pages, and pawn you real hard, real bad.
2. The bug comes from too much reliance on Tomasulo's algorithm for out-of-order instruction scheduling. It is not yet clear whether the bug can be fixed with a microcode update (and if not, Intel has to fix this in silicon itself). As far as I can dig, there is nothing that hints that this bug is fixable in microcode, which makes the matter much worse. Also according to my understanding a microcode update will be too trivial to fix this kind of a hardware bug.
3. A software-only remedy is possible, and that is being implemented by all major OSs (including our lovely Linux) in kernel space. The patch forces Translation Lookaside Buffer to flush if a context switch happens during a syscall (this is what I understand as of now). The benchmarks are suggesting that slowdown will be somewhere between 5%(best case)-30%(worst case).
4. Regarding point 3, syscalls don't matter much. Only thing that matters is how many times syscalls are called. For example, if you are using read() or write() on 8MB buffers, you won't have too much slowdown; but if you are calling same syscalls once per byte, a heavy performance penalty is guaranteed. All processes are which are I/O heavy are going to suffer (hostings and databases are two common examples).
5. The patch can be disabled in Linux by passing argument to kernel during boot; however it is not advised for pretty much obvious reasons.
6. For gamers: this is not going to affect games (because those are not I/O heavy)
Meltdown: "Meltdown" targeted on desktop chips can read kernel memory from L1D cache, Intel is only affected with this variant. Works on only Intel.
Spectre: Spectre is a hardware vulnerability with implementations of branch prediction that affects modern microprocessors with speculative execution, by allowing malicious processes access to the contents of other programs mapped memory. Works on all chips including Intel/ARM/AMD.

Update on my previous rants: finally got it working! after spending 2 days compiling the kernel and trying to fix some issues, I just reinstalled my laptop with a fresh antergos image, installed the kernel and both the speaker and headphones work just fine! no distortion, no weird chrome video speed ups, just works - it was probably just something I had installed ages ago to make external usb sound work.
I also used this opportunity to apply the missing grub theme and found this: https://gnome-look.org/content/... it's perfect with almost any custom background too.
Why is this a rant? well some asshat at gnome decided to remove the "global dark theme" option from tweaks, so now thousands of themes are broken if you want the dark theme, since the developers now have to offer the dark theme seperately, well numix-frost has had this reported since the 7th may and no response since, the hack to make it work is to replace the gtk.css with the dark equivalent gtk-dark.css for now..

To all the people complaining about a windows update breaking their computer.
A linux kernel update just broke my computer.7 -
I've got a confession to make.
A while ago I refurbished this old laptop for someone, and ended up installing Bodhi on it. While I was installing it however, I did have some wicked thoughts..
What if I could ensure that the system remains up-to-date by running an updater script in a daily cron job? That may cause the system to go unstable, but at least it'd be up-to-date. Windows Update for Linux.
What if I could ensure that the system remains protected from malware by periodically logging into it and checking up, and siphoning out potential malware code? The network proximity that's required for direct communication could be achieved by offering them free access to one of my VPN servers, in the name of security or something like that. Permanent remote access, in the name of security. I'm not sure if Windows has this.
What if I could ensure that the system remains in good integrity by disabling the user from accessing root privileges, and having them ask me when they want to install a piece of software? That'd make the system quite secure, with the only penetration surface now being kernel exploits. But it'd significantly limit what my target user could do with their own machine.
At the end I ended up discarding all of these thoughts, because it'd be too much work to implement and maintain, and it'd be really non-ethical. I felt filthy from even thinking about these things. But the advantages of something like this - especially automated updates, which are a real issue on my servers where I tend to forget to apply them within a couple of weeks - can't just be disregarded. Perhaps Microsoft is on to something?11 -
Yesterday (or the day before that depending on your timezone and day-night schedule - this Friday) my OnePlus 6T arrived. After only 2 days of time between placing the order and actually getting the phone, quite impressive!
The DHL guy asked me upon receipt - is it the OnePlus 6T? - Yes it is!! - "An amazing device it is!", he said. And honestly.. he couldn't be more right.
I might be a bit biased on this because after all I did just spend €630 on this phone. But it feels so snappy, high quality, the 8GB of RAM is just.. it blows my mind. But I'm sure that the other reviews did this sort of jazz already.
The things that set this phone apart for me though were the following.
When I get a new phone or tablet, usually the first thing I do is rooting it. This one was no different, about an hour after receipt it was successfully rooted and loaded with Magisk. Currently I'm still in the phase of "getting to know the phone", wherein fuckups are usual. This time again being no different - I removed some apps and apparently did something to it that the search engines - both Google and DuckDuckGo - didn't quite like, as both of them would crash upon application launch. Me in full panic mode of course, desperately trying to find the stock ROM (which doesn't seem to be present in its usual form) or a new set of GApps (which didn't resolve the issue). OnePlus does seem to offer its OTA updates in zip archives though. So I downloaded its latest update (same as what was on the device) and applied it.
That's when the nerdgasm happened.
The "update" was simply a matter of going into the settings, tapping this and that and applying the update. No recovery, no unrooting, no nothing. The update just went like that despite the phone being rooted and just having had TWRP flashed to it. I always wanted this sort of thing, which even the Nexus couldn't offer - having the cake and eating it too. Being able to root the device and muck around with it while still being able to update the device timely without too many hurdles. This fucking thing does it!!!
That is to say, after my initial nerdgasm I did find that it bulldozed over my su binary (effectively unrooting the thing), custom emoji I've set (iOS 12 because fuck Google's most recent emoji set) and some other things. But those are easy to install back, much more so than it would've been to download a whole Android release and dirty flash it, as it was on the Nexus.
Other than that, battery life, dash charging (edit: on that topic, it does remain cool like a cucumber despite getting 15-20W of power jammed into it, quite impressive!), snappiness, the usual jazz.. eh, as I said earlier that's the usual reviewer stuff. But this feature of being able to upgrade the phone while it's modified, that's something which seems to be severely underrated by those.
Oh and during kernel builds, I couldn't quite get the source to work - probably due to my lack of experience with builds of Android kernels - but I did find that this phone actually exposes its kernel config through /proc/config.gz as it should. None of my MediaTek devices do this, so that's something that I found really appealing. Always nice to see when a manufacturer exposes this information to give you a stock sort of config that you can be rest assured will work configuration-wise. And it allows you to see what the stock kernel is actually built with, which again is really nice. I quite like this! It really encourages further development.11 -
I was part of a on-call rotation. We had ~800 microsites with decent traffic on this one box, because that's a good idea...
One day the box was experiencing kernel panics and causing core dumps. After exhausting every possiblity I decided it was time to restart the box:
sudo shutdown now
Missed the -r and the box was not accessible remotely. Had to wait for someone at the data center to terminal in.
Downtime was ~2 hours.
This was caused by a crontab that automatically ran apt-get update & apt-get upgrade... Also made by me... None of this should have worked or allowed to be done! -
I bricked my Manjaro install by interrupting a kernel update like a fucking doofus.
After two hours of painstaking troubleshooting using a live image I finally resolved the issue. And man is that a good feeling. Solving complex problems (at least to me) on Linux is just such an amazing feeling ♥️12 -
Update on my previous kernel rant, I finally compiled it down to just 2.9GB! included all the needed modules and I am also able to boot off of it!
Great news is, that sound both on speakers and also through headphones work, bad news is, that there's some overlayed buzz/distortion, the playback is higher pitched and chrome for some reason plays videos "normally" if you set it to 0.5 speed, else the video get sped up in the "normal" speed setting, well fuck me, but atleast I am closer, also as always thanks to arch wiki, that has tons of resources.
It might be some of the quick hacks that causes this, that I used in the past to make sound work through an external usb card atleast, so might be worth it just reinstalling it all.11 -
"Linux is shit because nothing works on my new DOM 2017/2018 laptop!"
Yes it's true that nothing will work if you put your finking ubuntu 14.04 installation with a fucking old 3.13 kernel in your new Laptop!
Update. Your. Fucking. System.6 -
Casually debugging some cuda code today. Something's not working so I add a breakpoint in the suspicious kernel. For some reason I set the display GPU as the active device from my code *GENIUS* ( I have two GPUs installed, one for compute, one for the monitors).
Starts cuda debugging... Control flow reached the kernel and eventually the breakpoint. Suddenly the whole system freezes. Mouse doesn't move, keyboard seems dead. I realize I have unsaved code on the open text editor😲 *panic*. Keyboard shortcut to stop debugging doesn't work *panic^2*. My colleague says I have to hard reset the machine *panic^3*. I don't remember the last time I saved *panic^4*.
I take a deep breath. I reset. *sidenote: WINDOWS DECIDED TO FUCKING UPDATE ON REBOOT* Once I login, 50% of my code was lost. I didn't save 😢
Fuck you Nvidia 😢

5 stages of failing WIFI connectivity on Linux
This morning I woke up my laptop to start my work day. I have 2 very important meetings today, so I better get all prepared.
"Wifi connection failed"
Syslog says:
- wpa_supplicant: wlp9s0: SME: Trying to authenticate with <MAC>
- kernel: wlp9s0: authenticate with <MAC>
- kernel: wl9s0: send auth to <MAC> (try 1/3)
- kernel: wl9s0: send auth to <MAC> (try 2/3)
- kernel: iwlwifi: Not associated and the session protection is over already...
- kernel: wl9s0: send auth to <MAC> (try 3/3)
- kernel: wl9s0: authentication with <MAC> timed out
#### DENIAL #####
No biggie, let's try another AP (I have 3). All 3 failed to connect. Fine, let's try my phone's hotspot! FAILED!!!!!
w00t.... okay, let's restart the router... but failing to connect to a phone hotspot is already a worrying sign.
Wifi connection failed
wtf.. disable and re-enable wifi
Wifi connection failed
#### ANGER #####
the fuuuuuuck. Maybe my router is dead. But my phone connects to it, no fuss. My personal lappy also connects there easily.
wtf... Does that mean I'm about to lose my uptime?? Come one!! It's Linux - there MUST be something I could do! I don't see processes hanging in D state so the radio must be fine - it's gotta be a software issue!
ChatGPT – type all the log entries manually, via phone (that took a while...). Nothing useful there: update firmware, restart NetworkManager, etc.
#### BARGAINING #####
Alright... How about a USB dongle? Plug it in and wifi connects immediately! Yayyy!!! But that's only b/g/n and I'd very much like to have ac. It works well as a limping backup, but not something I'd use for the meetings.
rfkill block/unblock all the radios. No change. USB dongle connects right away but the PCIe adapter keeps throwing notifications at me with failure messages. It's annoying, to say the least.
So I've already tried
- restarting the router(s)
- disabling/reenabling the radios
- multiple APs
- suspending/waking again several times
- praying
#### DEPRESSION #####
The only thing I haven't tried yet is the most cruel one - restarting the laptop. But that's unfair... It's LINUX! How could it disappoint me. I have so many tmux sessions open, so many unsaved leafpad notes, terminal histories with oh so comfy ^r and ! retriggers all ready and waiting to be executed...
#### ACCEPTANCE #####
But I can't miss the meeting. So I slowly start closing off apps, starting with the least important ones, trying to preserve as much history and recent commands as I can. I'm gonna lose my uptime, that's the inevitable obvious truth... Linux has failed me. Or maybe it's a hardware issue... I can't be sure until I restart.
I must reboot.
#### A NEW HOPE #####
Hold on.. What if... What if before restarting I try to reload the Intel wifi kernel module? Just for the giggles. I've got nothing to lose anyway...
rmmod iwlmvm
rmmod iwlwifi
modprobe iwlwifi
modprobe iwlmvm
*WiFi Connected*
YESSSS!!!!!!!!! My uptime is saved!
403 days and counting! YEAH BABY!!!
Linux is the best!8 -
Our new hired (promoted intern) just installed Ubuntu on his new machine.
Now we are the only ones using Linux at work.
He was having trouble with a flickering bug on kernel 4.4.0 and I just told him to apt upgrade that it would solve it..
And he was like: oh.. Can you update the kernel?
That's gonna be a long month...hope he learns this faster than git7 -
24th, Christmas: BIND slaves decide to suddenly stop accepting zone transfers from the master. Half a day of raging and I still couldn't figure out why. dig axfr works fine, but the slaves refuse a zone update according to tcpdump logs.
25th, 2nd day: A server decides to go down and take half my network with it. Turns out that a Python script managed to crash the goddamn kernel.
Thank you very much technology for making the Christmas days just a little bit better ❤️
At least I didn't have anything to do during either days, because of the COVID-19 pandemic. And to be fair, I did manage to make a Telegram bot with fancy webhooks and whatnot in 5MB of memory and 18MB of storage. Maybe I should just write the whole thing and make another sacred temple where shitty code gets beaten the fuck out of the system. Terry must've been onto something...5 -
So my laptop is a Lenovo y50-70 and it's quite good. The keyboard is amazing compared to most other Laptops I've tried the screen is nice, it's durable and it's got some decent specs. With it (and also my desktop) I dual boot Kubuntu and Windows 10.
About three years ago I decided I wanted to reinstall both OS' since they were starting to get cluggered. Lo and behold I wasn't able to do that because, and I quote: "EFI USB Device boot failed".
Hours were spent trying to Google different things to the point where I was even desperate enough to go beyond page 0 on the different searches with (as you might have guessed), no luck. "Fuck that" I thought. It worked and I could clean it manually anyway.
Fast forward to the last part of August this year where I upgraded my Kubuntu from 17.10 to 18.04 and shit got weird. You can read more about it here:
https://reddit.com/r/kde/...
but the TL;DR is in the link. Windows was also quite annoing as well (but don't take my word for it).
As you might understand it made me really frustrated. I couldn't update my BIOS since they were already at the current version, but one way or another I had to fix it. After a while was almost about to give up when I decided to give this:
https://forums.lenovo.com/t5/...
https://bugs.launchpad.net/ubuntu/...
a go. It was weird though. Like imagine the conversation:
"Can't boot from USB bro, what do I do?"
"Just update your kernel, bro"
Well IT. FUCKING. WORKED.
So I imideatly installed Linux and have just now bothered installing Windows (since all of the teachers are vacation so I had plenty of time to set it all up).
But got damn.

1) Remove kernel linux
2) Change kernel to linux-zen
3) Make init ramdisk
4) Everythings great -> hit reboot
5) Stuck at Grub
Me: Fuck.. Forgot to update grub config.
(Lesson : RTFM first.)1 -
imagine having kernel memory leaks in 2020
AT&T or Huawei, whichever, pushed an update for my already-struggling-to-exist phone that made the kernel memory leak go from 480KB/hr avg to 22.5MB/hr avg. When my free RAM is never under 50% of 2GB after the kernel starts loading other shit and i'm able to express free RAM, at any time in use, in megs, with 8 bits... this means my phone crashes, with no apps running aside from a trimmed list of stock apps, every 3-4 hours due to running out of RAM. The only usable (read: not R/O because unrooted) swapfile is located on a tmpfs, so it's completely fucking useless (and eats another 100MB of RAM that I could be using for LITERALLY anything else, that's like another 3 hours of full idle between crashes) and I can't unlock the bootloader to fix any of this as Huawei no longer hands out keys and it'd take 7 years or so to brute (32-bit @ 10/sec)
tl;dr: fuck15 -
About a year ago, I started a new position as a Full Stack Java Developer. When I started my employer got me a brand new, shiny, Asus laptop. As I prefer Linux (mint) to perform my magic I had to whipe Windows 10 and reinstall it. It turned out that my new shiny laptop was in fact so shiny that Linux (mint) didn't support/contain all the necessary drivers (yet), especially the network/bluetooth drivers and the gfx's drivers turned out a bit of a pain.. Over the year things slowly got better with every new kernel update that came in. However, due to me trying to fix things before those updates, Linux also had become somewhat unstable.
So ... last week I took some time to re-install that laptop and also take the opportunity to upgrade from Linux mint 18 to Linux mint 19 ... or so I thought ... Linux mint 19 was running (very) hot to the point where the laptop would shutdown due to the MOBO's thermal protection mechanims kicking in. ... Ok ...maybe Linux mint 19 was not such a good choice .... let's see if Ubuntu 18.04 is an option ... Nope ... Linux would lock up within a minute after booting up ... no mouse, no keyboard ... nothing. .... *sigh* ... let's (re)install Linux Mint 18.3 again ... and behold, I can start performing magic again.
Linux, it can be such a pain at times. I still prefer it, but running into all those 'weird' things on my laptop when reinstalling, I have to admit I have seriously considered 'just' installing windows 10 again and be done with it. Luckily I could also remind myself of what a pain Windows is to do serious docker/java development in comparison to Linux which gave me the strength to keep going ... :)6 -
Tried to figure out why my computer was being slow and lagging earlier. Thought it may have been a bad update to the kernel I recently did, or an update to a package.
No, it was chrome and its horrible memory usage.7 -
Laying cozy on sofa, watching yt from phone. Decide there's a need for a bigger screen but too cozy to adjust position to watch from TV. Grab trusty old chromebook running Debian from arm's reach instead. Haven't used that thing in a while. Try to connect bt headphones. Notice that the Bluetooth module is not detected according to the UI. Weird, never noticed that. Wonder what that's about. Apparently someone had fixed it in kernel already long ago, I'm on a much newer kernel. Too lazy to pick up wired headphones from across the room. Maybe I'll update the firmware, I haven't done that in a while. Oh, the script doesn't run because it requires newer glibc. Wait, I'm still on Debian 11, maybe it would be worth it to upgrade to 12. Wow, upgrading Debian is a surprisingly manual process. Wonder what I'll be doing tonight. Wait, what was I doing again?14

After ages of waiting for it too install, i finally managed to update my kernel to the latest version.
And i know its not good to have a unstable kernel but screw you.

I'm freaking done trying to get Linux on my machine. I've tried every distro with many different versions of the kernel and I always run into the same problem on my desktop.
The computer super stutters for 2 seconds ish than freezes.
I've spent DAYS looking into this issue trying to find something. The worst part is that it can happen 5 minutes when I boot or 5 hours. At first I thought it was Compton. Then I thought I installed arch wrong. Maybe an update to the BIOS? How about downloading updated microcode? Maybe this obscure bug with AMD processors and setting power idle to typical? Nothing. I'm now behind on my school work because of the massive amount of time ive spent getting this fixed. It works just fine on my laptop, but it doesn't work on the machine I built to code with. I'm done. Give me Force Lightning, a red lightsaber, and call me a Sith baby because I'm joining the dark side. Here I come Windows.
For those who are wondering my setup:
Ryzen 7 1700
Rx 480
Asus x-370 prime
16 gb Corsair RAM
And no, Windows has never had this bug.31 -
Last night: Wow, I just finished that massive feature and I still get some time left! Why not play something?!
Oh crap, this game is so cool but my video card drivers needs an update (AMD Radeon on a Fedora system).
The proprietary drivers don't run on this version of Xorg server... Fine, let's search for some solutions online and... Hey! Found it! Let's see: downgrade Xorg, download the driver, patch it for your kernel version...
Did I just fucked my display? Oh yeah... Let's try to fix it........
Fuck...
5am: Finally got it all working perfectly again... Fuck this game, I hate it!3 -
Okay so my brother in law has a laptop that is... To put it mildly, chockful of viruses of all sort, as it's an old machine still running w7 while still being online and an av about 7 years out of date.
So my bro in law (let's just call him my bro) asked me to install an adblock.
As I launched chrome and went to install it, how ever, the addon page said something like "Cannot install, chrome is managed by your company" - wtf?
Also, the out of date AV couldn't even be updated as its main service just wouldn't start.
Okay, something fishy going on... Uninstalled the old av, downloaded malware bytes and went to scan the whole pc.
Before I went to bed, it'd already found >150 detections. Though as the computer is so old, the progress was slow.
Thinking it would have enough time over night, I went to bed... Only to find out the next morning... It BSoD'd over night, and so none of the finds were removed.
Uuugh! Okay, so... Scanning out of a live booted linux it is I thought! Little did I know how much it'd infuriate me!
Looking through google, I found several live rescue images from popular AV brands. But:
1 - Kaspersky Sys Rescue -- Doesn't even support non-EFI systems
2 - Eset SysRescue -- Doesn't mount the system drive, terminal emulator is X64 while the CPU of the laptop is X86 meaning I cannot run that. Doesn't provide any info on username and passwords, had to dig around the image from the laptop I used to burn it to the USB drive to find the user was, in fact, called eset and had an empty password. Root had pass set but not in the image shadow file, so no idea really. Couldn't sudo as the eset user, except for the terminal emulator, which crashes thanks to the architecture mismatch.
3 - avast - live usb / cd cannot be downloaded from web, has to be installed through avast, which I really didn't want to install on my laptop just to make a rescue flash drive
4 - comodo - didn't even boot due to architecture mismatch
Fuck it! Sick and tired of this, I'm downloading Debian with XFCE. Switched to a tty1 after kernel loads, killed lightdm and Xserver to minimize usb drive reads, downloaded clamav (which got stuck on man-db update. After 20 minutes... I just killed it from a second tty, and the install finished successfully)
A definitions update, short manual skimover, and finally, got scanning!
Only... It's taking forever and not printing anything. Stracing the clamscan command showed it was... Loading the virus definitions lol... Okay, it's doing its thing, I can finally go have dinner
Man I didn't know x86 support got so weak in the couple years I haven't used Linux on a laptop lol.9 -
First of all, a great channel to follow and where all this is from: https://youtube.com/watch/...
It listed a lot of open source news I missed myself and I'm sure others did too, for those that are too lazy to watch the video or open the description, I've stripped away the links and "X version got released" just to give an idea of what he covers.

fuck oracle. fuck my company.
Using Oracle VM Manager/Servers to host Oracle Phone transfer solution without support coverage from Oracle.
Requiring Unix sysadmins to update to latest release and not telling that we do not have coverage from Oracle if anything goes wrong.
Gues what.. We've updated to Oracle VM Manager/Server 3.4.5 which was released this year and it uses fucking XEN hypervisor version 4.4.4 which has been deprecated and dead since who knows when. Latest release of XEN is 4.11. But that is not an issue, whatever, enterprise, legacy software, etc.
This fucking update introduced memory leak on the hypervisor which has been reported as per xen 4.4.4 history. Furthermore, we have no support from Oracle which means that I have to dig through mailing lists and limited information on the net since oracle has freakin support wall on nearly each of the major bugs found on that shitty software.
I have no idea whether any newer version of xen will work with that old Oracle Linux kernel or not.
Furthermore, Oracle provided great documentation on how to rollback the fcking update. Reinstall the hypervisor. Riiiight. XEN does not have export/import feature.

FUCK YOU SYNOLOGY
Fuck you for breaking all my custom shit.
Fuck you for wiping almost everything (but leaving random stuff) every major update.
Fuck you for switching from upstart to systemd 219 (RELEASED MARCH 2015!).
Fuck you for using an outdated kernel.
Fuck you for having the weirdest shittiest preconfigured settings.
Fuck you for using your own custom package format.
Fuck you for being so utterly broken.
Fuck you for making me work 10 hours just to get everything back up and running the way it was.

Quick question/update over a previous rant.
My netbook battery status was always 100% on Lubuntu 18.10, I switched to Xubuntu and the same happens, but it reports correctly with Puppy Linux (old version). I thought the problem was in the battery itself, but now I think it's due to some broken drivers in newer version of Debian-based distros, or it is a bug in newer Linux kernel. But since I have no time to spend on a spare netbook, I'm not willing to test more options.
Anyone has a clue? 🤔

TL;DR: Fuck fucking Arch fucking Linux. Gentoo. Yay or nay?
So over the last few days my arch install has gone to hell. A small install of a package brings up some other update as it needs an updated version, then shit starts to segfault. I've been compiling anything and everything from sources rather than using pacman, and it works great. My DE has an issue with animations and does a FULL FUCKING KERNEL PANIC when I as simple as change what virtual desktop I focus. I'm genuinely so fucking done with Arch and I wish to change. I'm not touching Ubuntu with a 10 foot pole, nor any other Debian shit, so I'm wondering whether Gentoo might be it. Anyone got experience with it? Worth a shot for an experienced linux user?6 -
Actually have a dev thing to say now.
I wrote a script to compile my kernel with the latest mainline version using my current config options. It works...so far. I'll check back with it in a couple months and hope it still works good. It also checks daily if my kernel is out of date (yes I'm one of those, fight me)
Also managed to get my laptop to boot from power on to LightDM in 15 seconds, and 9 of those seconds are firmware. It DOES have this thing on occasion where it freezes during the boot process while initializing everything tho?? I've been meaning to try and figure it out for a minute but I put it off so much cause I don't reboot that often anyways.
As for a personal update, I hung out with some good friends today and my best friend heard my singing voice for the first time, she said I have a good voice (she does a lot of musicals and stuff and just sings all the time, so I trust her opinion). I also gave that friend a gaming laptop as a late birthday gift/early graduation gift today because she doesn't have anything to game on and I didn't really use the laptop much anyways. Plus she's like my favorite person ever and she really deserves it. Unrelated note, I have had an off and on crush on this girl for 2 years. She's always been there for me and she's just an amazing person.9 -
Anyone else getting a bug with every opengl application on Linux? Gives me an error something like "X error of failed request: badvalue"
Weird- maybe happened in the latest kernel update? I'm using 4.147 -
Fucking nvidia and its fucking proprietary linux drivers. Of course I had to attempt an update, because the game was freezing, and of course it ruined my Friday evening. Because the newest kernel apparently cannot even boot (with any version of the proprietary drivers).7

Why did Microsoft lock down TTF files?
https://support.microsoft.com/en-us...
None of their links work anymore.4 -
Nothing like a fucking kernel corruption after Ubuntu update and restart.
It's so great
Really
My two hard drives now are encrypted and to unlock them the kernel should be intact.
The amount of time it'll take to reconfigure my machine to work is insane.
Also, I had commits in products I'm working that weren't on remote. So fuck me.
Now I have to do a fresh install and hope that I can read my second drive.17 -
At the end of my shift I updated my work linux with corporate update, shutdown and go home. Next day I come to work, try to boot up but ends up in kernel panic.
tfw I lost my personal scripts and projects.
tmw when whole department has bricked computers.2 -
tl;dr Which new laptop + Linux distro combo should I get when seeking for minimal configuration and maintenance hassle?
Hey devRant gang!
I'm looking for a new laptop: which one is supported out-of-the-box by Ubuntu based Linux distros like Elementary OS?
Why Elementary OS you ask? Well, I want to move away from macOS and/but keep the minimal (and pretty) design/interface!
But: I don't want to waste time configuring stuff after install or a kernel update. I don't have time for that: I need to get shit done.
As much as I dislike closed source/evil corporate stuff the fact of the matter is that my MacBook Pro Just Works (and lets me get shit done).3 -
Let me tell you about my wonderful weekend. It all started with a game that doesn't run in wine and it ended up in the biggest nightmare of Windows Update and EFI configuration.
1 - let's boot on my Windows partition to play trackmania 2.
2 - Windows Update interrupts me while driving a track.
3 - Update keep failing over and over again.
4 - I keep trying things to fix Windows Update, but with no success.
5 - Let's try system restore, failed
6 - Let's try to do a reset. "You don't have a recovery drive". Oh, right...
7 - Let's try to upgrade Windows 10 to Windows 10, just because. Nope, "we could not determine if your pc can run Windows 10". Wait what....
8 - I guess I'll be reinstalling this trash. "Nope, can't. Don't like that partition I just formatted". Of course you can't...
9 - Had to delete the partition and let it create new ones. It created a new EFI partition. Just why???
10 - Okay that worked. Let's fix grub now.
11 - Maybe not, let's try rEFInd, because it looks fancy.
12 - After rebooting on the live USB for about 50 times and reconfiguring rEFInd without any luck, I realised the install script didn't install fs drivers for ext4. Oh, right... That's why you didn't find any Linux kernel...
13 - It can't boot windows, they're using a different EFI partition. Let's move rEFInd to the new EFI partition windows created for me.
14 - Finally everything works again. So much effort to play a freaking game without being bothered by windows update. And rEFInd abience theme looks beautiful.
I've got to say though, I learned a lot and the Arch wiki is awesome!6 -
Just saw that Ubuntu 19.04 extended the live patching option to desktop users and we no longer have to restart the system after a kernel upgrade.
And here we have windows which restarts after every bloody security update.
How come Microsoft is such a big shit that they can't put a feature like this in WIndows. They definitely have the resourses and the people. I think they are just lazy and don't think it's "important enough"11 -
A colleague of mine has built a kernel module that is part of our system. He wrote it for Linux 4.4 but in the meantime our servers got updated to 4.15. The kernel API changed from 4.4 to 4.15 so the module does not build anymore. He said he will update it, but in the mean time I figured it would be easiest to just use 4.4 in the meantime. I downloaded the kernel deb package and installed it. Now, after reboot I can't ssh into the machine any more. I just started this project and I'm already tired of it. Every time I fix something a new issue appears. And I did not even start what I am supposed to do1

Finally decided to work on my kernel update script a bit (basically I compile the mainline kernel and configure it to slim it down a ton for my laptop, and that gets annoying so I wrote a script to do it for me). As of right now it is functional, it MAY require some babysitting, cause sometimes shit goes wrong, but it hasn't given me any problems the last few times I've run it. But it's also written with Arch in mind (using linux-mainline AUR package), because I use Arch btw. At some point in the future I want to add support for other distros, but I also want to get everything functional on Arch first.
If anyone has any suggestions or anything:
