Systemd, I fucking love you. When a service crashes, let's just keep it turned off, don't restart it on your own, no need for that. That's what statefulness means, right Poettering? Such an amazing init, well worth the quarter GB of code or however much it is now. And yes I know that the unit files can be edited to achieve that. But seriously, should I really have to do that for each individual service on each individual box, because systemd can't do it on its own?
That feeling when an init system is (relatively) decent at doing everything else it absorbed into itself, yet fucking sucks at being.. a goddamn init. Good game Poettering. Such an amazing init system you wrote there. God fucking dammit man.. how hard can it be? There's OpenRC and BSD's /etc/rc.conf which are literally mere kilobytes of scripts and they do both statefulness and parallelization (in case of OpenRC anyway) *excellently*. Yet systemd can't even do that much? Awesome. Great init. I love it.
Come fucking on man...20 -
Another case of "devs too stupid to poop" TM.
We had a funny discussion today.
Topic came up that a project using Lucene was incredibly slow.
Then came the yadda yadda of Java bad, Java sucks, Java bla Java blub in the gossip mill.
Both things irritated me, last thing was just the usual "I want to use new stuff cause I wanna be a cool jackass" trouble.
So. Today meeting. We did quick analysis by pair programming.
If I tell you that a whole team managed to review an PR, give it green light...
Despite the PR using the thread safe Lucene IndexWriter in a non-parallel fashion for large bulk inserts?
The whole problem screamed parallelization.
Yeah. If you ignore that scream and implement it in a sequential fashion, it is slow.
Congrats Jimmy, your retard level is off the charts. -
Added a bond interface in my Proxmox installation for added cromulence, works, reboot again, works, reboot once more just to be sure, network down.. systemctl restart networking, successfully put the host's network back up.. lxc-attach 100, network in containers is still down apparently.. exit container, pct shutdown 100, pct start 100, lxc-attach again... Network now works fine in containers too.
Systemd's aggressive parallelization that likely tried to put the shit up too early is so amazing!
I'm literally almost crying in despair at how much shit this shitstaind is giving me lately.
Thank you Poettering for this great init, in which I have to manually restart shit on reboot because the "system manager" apparently can't really manage. Or be a proper init for that matter.

And yes I know that you've never had any issues with it. If you've got nothing better to say than that then please STFU. "Works for me" is also a rant I wrote a while back.12 -
TL;DR: Embedded software guy needs to create a multi-instance sandbox environment in Jenkins for testing and not sure what good solutions are out there. Looking for suggestions.
So at work, we have these really cool integration tests that validate our system for flight safety. What's not so cool is that due to factors outside of my control, each test has to be run serially and the entire test suite can take many many hours. This is mostly due to a hardware limitation (not enough physical NICs), but there are other SW factors as well.
What I would like to do is somehow be able to wrap up all the resources into a neat little package and then deploy that package into some kind of virtual environment that can be instantiated on a Jenkins job. The NIC issue would be replaced with a virtual one and *theoretically* I should be able to spawn as many instances of this virtual environment as my CPU and RAM can handle. In short, I want to pseudo parallelize our test suite and drive down our testing time. Somehow I would need to be able to control this entire thing from a script of some sort.
Does anyone know of something out there that would satisfy these kinds of requirements? Double internet points if it's open source.
