I'm just amazed what 512MB of RAM can do :O
That's htop from my VPS I feel sorry for the CPU though.
It is running three docker containers:
1. Dotnet Core
2. MySQL
3. OpenVPN

TL;DR
I accidentally surpassed(?) my user permissions and closed some of my classmates browsers and locked up a terminal for me
In school we have 2 primary operating systems: Windows and Ubuntu. Windows is hell in general and but not as hell as the firefox installation on Ubuntu.
"Just loaded this page. Now wait half a minute so that I can render it"
"Woah, woah, woah. Slow there. You just made an input event. Give me those 5 seconds to compute what you just did"
Executing "top" or "htop" shows you a long list of firefox processes with a cpu usage of 99.9%, since the whole school shares that linux environment.
Anyway, one day it was way more servere than normally and I way forced to kill my firefox instances. So I pressed CTRL+ALT+T for that terminal, waited 5 minutes until it accepted input typed "killall firefox" with a delay of half a minute per character and smahed that enter key.
At this very point in time I could hear confusion from every corner of the room. "What happened to firefox?"
Around 30% of the opened browsers where abruptly stopped. I looked back to my screen noticed I was logged out. I couldn't login from that terminal for the rest of that day.
Our network admin, which happened to be there, since the server is just next door, said that this was just convenience, but the timing was too perfect so I heighly doubt that.
I felt like a real hackerman even if it was by accident :)8 -
when i was fired as an external contractor with half an hour notice, because i didn't process enough tickets. I didn't process many tickets because:
1. In the morning everyone grabs tickets just to stop the timer.
2. I worked on some complicated tasks that involved multiple third and fourth parties(not to forget an fucking dropping firewall)2 -
Things that I always install and configure in a server:
automysqlbackup, rsnapshot, htop, zsh (oh-my-zsh)7 -
When every ubuntu based distro fails, from kubuntu to xubuntu, lubunto, mint etc.
You will always have Linux Lite. How the fuck this thing manages to keep 2 vs code editors opened as well as firefox and chrome at the sime time while at 3.55g mem(according to htop) without fucking up?
Good engineering, das how. Kudos to my ninjas at the Linux Lite team. This is why I recommend this distro to anyone wanting to go Linux. Good for the beginner and the working professional alike(I use it for work)4 -

A functional system bar for my window manager in Go. It's so light on system resources that htop can barely report its system usage. Also, I haven't changed anything in the code in a year and it still works perfectly.2

Mom: my photos are gone. Can you find them?
Me: *searches the phone an finds nothing.*
Me: i cant find them.
Me: *Tries to copy 5GB of random Data*
Phone: Copy Error
------------------
Its a noname china phone my Father bought. I warned him about it, because they stole the Samsung design and it said that it was Version 8.1, but didnt had the features 8.1 has
------------------
Me: The Phone deleted it.
Mom: why would a Phone delete my Photos?
Me: because the manufacturer wanted to maximize the money he can get and made an device with higher specs on the paper than it has and manipulated the internal tools to hide this.
------------------
My father asked me why she is so furious. I said to him: because you got screwed so easily.6 -

i cant stand these idiots anymore. My instructor needed 12 Minutes to understand Megabyte and Mebibyte. He just used the snipping tool to save an SVG from Wikipedia. My instructor is an Person who wrote small Programs in the past and thought that an instructor license is something useful. It hurts listening to him. he was kept busy for hours because of nothing, so we could only twiddle our thumbs. our first instructor went probably because of the Management.
At the beginning of June I will give my lecture for my final exam.

Yay, Dubba didnt die.
Okay, hello'ed back, lets fucking rant.
Im fucking SICK and TIRED and ANNOYED by all freaking cloud fanboys. Yeah, sure. You get scalability. You waste less resources. Sure. But it depends on use case. There is suprising ammount of services that can be run on VPS or dedicated servers that will be a lot cheaper if you just DONT run it on cloud. And dont you dare to missinterpret me. I fully recognize that there are valid uses for cloud services. But for fuck sakes, its not anwser for ALL of your needs, and it costs insane ammount of money if you use it where you should use dedicated.
WHY we, as humanity came to this place where self-claimed "proffesionals" will anwser you "cloud" before you even ask your question.
No, fuck off, take calculator and think for around 60 seconds. And than decide if you need cloud or not.
And no, this mail server will be fucking few times more expensive on cloud, and I know it becouse I have fucking calculator and I was running it past 1.5 year and actually run sometimes htop, so stop bullshitting me.
Sorry if some cloud die-hard felt offended but it is exacly how I see and feel it.
Peace.1 -

I have this colleague that who is nice, but if you mention anything about (not complete) java, sun, vmware, windows, daus(dumbest possible user), car manufacturer your ears bleed with is rants about it.
For example:
We talked about BMW which published that the energy generated from recuperation of one of their cars is around 60%. Immediatly he rants that it its not possible and the calculated number of an forum user of the newssite who calculated that 90% of the kinetic energy is regenerated has no idea about the problems.
Sometimes its hard to endure the hate, but i can relate with him in some things.2 -

All the procrastinating in my schooltime.

They haunt me till today among other things.1 -
Wanted to work from home as usual. Logged in in citrix with my credentials and totp, started rdp to connect with the bank.
i try it for the first time: failed to connect
I try it for the second time: error 0x112d (some thing about two programs that have an the same port open)
I ask my colleagues to look after the pc in the office and what was it:
FUCKING WINDOWS UPDATE FILLED THE RAM COMPLETLY.
Luckily no data was lost, since i had everything important commited and pushed.3 -
In last episode of "How SystemD screwed me over", we talked about Systemd's PrivateTMP and how it stopped me from generating SSL certificates.
In today's episode - SystemD vs CGroups!
Mister Pottering and his team apparently felt that CGroups are underused (As they can be quite difficult to set up), and so decided to integrate them into SystemD by default. As well as to provide a friendlier interface to control their values.
One can read about these interactions in the manual page "systemd.resource-control"
All is cool so far. So what happened to me today?
Imagine you did a major system release upgrade of a production server, previously tested on a standalone server. This upgrade doesn't only upgrade the distribution however, it also includes the switch from SysVInit to SystemD. Still, everything went smooth before, nothing to worry now then, right? Wrong.
The test server was never properly stress-tested. This would prove to be an issue.
When the upgrade finishes, it is 4 AM. I am happy to go to bed at last. At 6 AM, however, I am woken up again as the server's webservices are unavailable, and the machine is under 100% CPU load. Weird, I check htop and see that Apache now eats up all 32 virtual cores. So I restart it, casting it off to some weird bug or something as the load returns to normal.
2 hours later, however, the same situation occurs. This time, I scour all the logs I can, and find something weird - Many mentions that Apache couldn't create a worker thread? That's weird.
Several hours of research and tinkering later, I found out the following:
1 - By default, all processes of a system that runs SystemD are part of several CGroups. One of these CGroups is the PID CGroup, meant to stop a runaway process from exhausting all PIDs/TIDs of a system.
This limit is, by default, set to a certain amount of the total available PIDs. If a process exhausts this limit, it can no longer perform operations like fork().
So now, I know the how and why, but how should I solve this? The sanest option would be to get a rough estimate of just how many threads the Apache webserver might need. This option, though, is harder, than apparent. I cannot just take the MaxRequestsWorkers number... The instance has roughly double the amount of threads already. The cause being, as I found out, the HTTP/2 module, which spawns additional threads that do not count towards this limit. So I have no idea what limit to set.
Or I could... Disable the limit for just the webserver via the TasksAccounting switch. I thought this would work. And it did seem to... Until I ran out of TIDs again - Although systemctl status apache2.service no longer reported the number of tasks or a task limit of the process, the PID CGroup stayed set to the previous limit. Later I found out that I can only really disable the Task Accounting for all the units of a given slice and its parents.
This, though, systemctl somewhat didn't make apparent (And I skimmed the manual, that part was my fault)
So... The only remaining option I had was to... Just set the limit to infinite. And that worked, at last.
It took me several hours to debug this issue. And I once again feel like uninstalling systemd again, in favor of sysvinit.
What did I learn? RTFM, carefully, everything is important, it is not enough to read *half* the paragraph of a given configuration option...
Oh, and apache + http/2 = huge TID sink. -
it was the last time i used PHP for an school project. i and an other group decided to make an website. it was luck that no input was required. Because i already knew PHP and HTML i need to help them. the code they made was the cause i quit php. the site only worked after an redirect. it was irony that tje code looked like it was written from a junkey and the theme was drugs.7

Why the fuck does a windows server 2016 guest with ballooning service on proxmox take the full 10GB RAM from the host I assign to it?
I have installed all the virtio drivers and it does show in the guest summary itself the real usage of 1GB RAM, but if I check in htop or the datacenter summary, it shows the usage is 10/11GB all the time.17 -

When i was fired in a few minutes in my first meeting with the boss since i was working there.
but now im glad im out of there. The kpis they use to see how someone performs are utterly useless.6 -
Probably the one where we had an error, because the service from a thirdparty we needed to install used a fourthparty service that was behind a proxy. Due of internal reasons we needed to use our own tomcat instead of the standard tomcat. We made a meeting because we didn't found out at that point that the problem was the firewall that dropped the packages from the application. We replayed it to them (at that point it was in my musclememory) and after a month i got the idea to use tcpdump to see if the server is calling another webservice, which was denied by the developers.

How do you do bootstrapping of blanko machines?
Imagine you get a linux/BSD/osx machine and you want it set it up to a defined state to be prepared for further setup.
Like users
ssh config
Sudoers file
Config management client or credentials
Software like vim, htop and tmux
A simple shell script sounds a bit archaic to me and i was wondering, if there is a better way...
Makefiles also came to my mind but still... Unsatisfactual4 -
short: The admin with enough xp is ill, there is no one with xp with varnish is and after 1 restart varnish outputs only 503.
long: there original admin is ill but he gave me an project to migrate an typo3 installation to a new server. Thats ok.
Plan: I move 150 GB of data with rsync to the new server, let specialists do something and switch ips between the new and old and clear varnish with a restart.
Reality: +2 hours to migrate the data, because of false infos from the admin, 7 hours preparing the switch, 5 minutes switch, 3 hours to find out the F*****G varnish is the single point of failure. I and the t3 guys agree to see the next day what went wrong.
ALL HAPPENED TODAY!
Plan for tomorrow: speak with the boss to account the extra hours to that day so i dont get over 10 hours and debug that fucking varnish and delete some servers from another project from the backupsystem and monitoring.3 -

Somebody: (whinwy) we need something to log into nonprivileged technical accounts without our rootssh proxy. We want this pammodule pam_X.so
me: this stuff is old (-2013) and i can't find any source for it. How about using SSSD with libsss_sudo? Its an modern solution which would allow this with an advantage of using the existing infrastructure.
somebody: NO I WANT THIS MODULE.
me: ok i have it packaged under this name. Could you please test it by manipulating the pam config?
Somebody: WHAT WHY DO I NEED TO MANIPULATE THE PAMCONFIG?
me: because another package on our servers already manipulates the config and i don't want to create trouble by manipulate it.
Somebody: why are we discussing this. I said clearly what we need and we need it NOW.
we have an package that changes the pam config to our needs, we are starting to roll out the config via ansible, but we still use configuration packages on many servers
For authentication as root we use cyberark for logging the ssh sessions.
The older solution allowed additionally the login into non-rootaccounts, but it is shut down in the next few weeks after over half an year of both systems active and over half an year with the information that the login into non-privileged accounts will be no more.7 -

Bullshittery continues. This time around, absolutely innocent, clamav is root cause. For once not incompetent idiot, but piece of software. IDK if that makes me happy or upset.
So our email server that I configured and took care of died. RIP. Damn, better put it back together ASAP. So Im under pressure, while still pissed at everything that I ranted before (actually my last 2 rants were throttled, and in total all of that happened past 60 minutes but devrant rate limiting) I start auditing logs. You imagine, we kindda need it NOW, and it's second time last month clamav is pulling stunts and MTA refuses (properly) to work without antivirus. So pressurized, I look at logs, what the fuck went wrong.
clamav deamonize() failed - cannot allocate memory
Hmm. Intresting, but sounds like bullshit. I know server is quite micro becouse they wanted to save on costs as much as possible, but it has well over half a gig free ram just before it crashes (like 800MB) with that message. Is it allocating almost gig in one call or what? Looked carefully at trusty htop while it was starting, and indeed, suddenly it just dies with quite a bit of ram free, almost as much as it weights already. And I remember booting it up when I was configuring it, and it had fair bit of headroom.
Google, help me friend... Okay, great, so apparently at some point clamav loads virus DB into ram (dafuq?), and than forks, which causes spike of 2x the ram usage, and than immidietely frees it up.
Great, that sounds like great design decision... At least I know, I can just slap on SWAP file, restart it and call it a day.
It worked, swap file is almost empty (used 15megs, 900 megs free ram, whatever).
That leaves me wandering, who figured out to load DB to ram? That means pretty much that clamav will eat a little bit more ram each vir db update, and that milisecond "double ram" spike will confuse innocent people who just wanted to run clamav and it worked last *long period of time* and now crashes without warning without any changes to configuration.
Maybe there is logical explanation, I want to know it.8 -

The best ones are in my opinion the ones that are easy to use and don't need a manual to exit(i look at ypu emacs). This is a list of tools that i use only if nothing else is available:
- nodejs directly

Any recommendations for a terminal app for iPad? I only need it to ssh into Linux servers and run stuff/vim/htop/etc., don't really care about fancy features or local device access. Good performance and security would be pluses. I don't mind paying if it's worth it. Coming from Termux on Android the ones I've tried so far (Termius, Shelly, LibTerm) have felt pretty crap so far, though I guess Shelly is the best one out of them.1
