as /u/FigMcLargeHuge mentions, recent logfiles in /var/log. Notably /var/log/messages (EL) and syslog (Debian) but anything that's recent.
journalctl - More and more things are moving to binary logging. If you know the process, then journalctl -u processname restricts to just that. also add a -f for tailing it for ongoing logs.
dmesg -T - especially at system level, this captures any hardware/low level logs. (-T reports actual times, not just seconds since boot)
Once you have some logs that you think are related, but don't know WTF they actually mean, you have two options. The first is to google likely strings. This is... ineffective much of the time - accidental misinformation and outdated advice is increasingly common. The answer might be there, but it takes time and can be frustrating to weed out the cruft.
The better way, (IMO, and people downvote me for saying this) is to use AI. Get a few lines of logs with the errors, check them for confidential information, and simply paste the suspect lines into chatgpt, gemini, claude, co-pilot, whatever. No need for context, it'll figure that out. The LLM will, 4 times out of 5, identify the problem very quickly.
Now, once it's identified that, it will offer to fix it for you. This is where you've got to be on your toes as LLMs are really really quick to give bad advice at this level. But that first triage is nearly always worth doing and helps shape your own mind as to what's going on. AI is still useful for fixing it, but do understand what it's telling you to do.
It's technology like this that I think will become more and more important as governments seek to restrict access to large parts of the internet. UK and Australia are forging ahead in censorship, and the EU is well on their way. The US already does some censorship, as do large parts of Asia and Russia.
No matter the reason given, it's always about control. So less easily censored technologies will be very useful for anyone that wants the ability to research truth, or at least, alternate points of view.
I understand having a dislike for a medium that encourages shallow, gimmicky, reactive content
That's all social media.
And Reddit has a huge amount of reposting/karmafarming bots as well as a lot of political/troll botfarms targetting it, and a lot of human trolls. And if you don't have an adblocker, a sometimes miserable user experience. But Reddit also has the biggest userbase by a huge factor, a lot of really interesting subs with some really good content and people.
You can find positives and negatives about any platform or, really, anything anywhere. At least with social media platforms we have a choice as to whether we engage or not. That's how you avoid the trash if you think the pool is full of shit - don't swim in it.
Honestly, if someone genuinely believes "everything is shit" then maybe the problem is with them.
That's like saying "I read a book once that I didn't like, so all books are shit"
Tiktok is like all other streams - there's a huge variety of content and it includes a lot of good and innovative creators. Yes, there's a lot of utter shite, just lke reddit, facebook and even Lemmy.
But there's also people who spend time making something good, sharing interesting things about their day and teaching what they know.
It sounds... very odd, and I'm interested in knowing the reasons for apparently breaking the law, especially in what seems to be a clumsy and legally difficult way. What did they hope to achieve? I note from the Guardian's article that Ansari has already started legal proceedings against the home secretary and the chief constable of north Wales police.
What is Bob good at? Is any of his skill set useful to the team as a whole? If not, to the department? Then to the company? A sideway move might help everyone.
You say you've tried to train him, but has anyone else? Sometimes two people just don't click enough to learn/teach together through no fault of either.
Ultimately, if nothing you think of can help, then you need to talk to HR and work with them about a performance improvement plan.
Re-reading your message, it seems you're not his manager. In which case this isn't your job. If he is affecting your ability to do your own job, then you need to talk to your manager.
