General Discussion / Re: Mark Greaves (PC Netspec) - Passing Away
« on: January 15, 2020, 09:05:03 pm »
I'm afraid I'm almost at a loss for words, Mark was one of the most of the likeable and helpful people I know and has done a massive amount for the community and in particular people who frequent these forums where he's answered everyone's questions and kept the peace for the these last 10 years. There's more on the Peppermint forums here; https://forum.peppermintos.com/index.php/topic,9283.0.html
Mark - you will be sorely missed. R.I.P

General Discussion / Re: Is there any legitimate use case for "rm -rf /"?
« on: January 15, 2020, 08:39:13 pm »
Hi David,

I once watched a gobby consultant type in "rm -rf /*" on the console of an IMB RS6000 running AIX, in front of a client, while bragging about how the UNIX system was so great it could withstand such a command. I cautioned him (in front of said client) not to press return, a caution that was met with much displeasure and an insistence that of course he would not actually press return .. at which point he did in fact, accidentally press return.

I immediately left the building, however I did hear that he was on-site for the following three days and never returned to our office (!)

In general it's Linux's job to do what it's told and the user's job not to be an idiot careless.  ;)  .. there are always special cases, but you never know when someone might actually want to do something that you think they shouldn't .. Off the top of my head, I think you can mount an overlay filesystem on top of "/", which is how "live CD" systems used to work .. in which case "rm -rf /" should strip any changed files from your system (?) leaving it running on the underlying (possibly read-only) file-system .. or if you mount "/" read-only, "rm -rf /" might remove any RW files from non-root mount points. (although I've not tried it)

Lincon, your post seems incomplete - did you miss something off?

Ok, this was a really good catch, spotted a generic issue that's been bugging me for a while - should be fixed, please let me know if you're still seeing a problem.

Working for me, so long as you enter a valid user name. "mark" will not work as this isn't a valid name .. if you use "madpenguin" it works, or "mark.greaves@linux.co.uk" it works .. I think your username is "mark greaves (pcnetspec)", not tried it, but I suspect this will work too ...

Erm, it's an alternative to Google analytics, the difference being you see the analytics in real-time, rather than as a historical view ...

Ok, had an initial issue with the changes interfering with posts so I partially backed out of one section, but I've fixed that now (or I have if you're reading this  :)  .. also fixed a couple of minor issues left over from the http->https upgrade a couple of weeks ago, and a theme/css issue from the last SMF upgrade. (still tweaking)

Hi, if anyone has a little time tonight, I'm trying to put together a screenshot of some new software I'm writing but I need a few people from different geographical locations to browse a website to get a decent picture. So, if anyone is able to bring up "https://linux.co.uk" in a browser and leave it open in a tab over 10pm, I would be very grateful.

it's a "real time" Analytics plugin for wordpress so you can see who's on a given site at any given point in time, which page they're on and which pages they've visited.


Essentially I'm after a "better populated" version of this;

With rolling daily totals;

Ok, I'm going to stick my neck out and assume that the installation is *not* older than the hard drive. Which means the hard drive is more than likely 8 years old .. given the average lifespan of a hard drive is around 3 years, you're more than a standard deviation or two into borrowed time.


That aside, the symptoms you describe sound a little like a failing hard drive.


I would recommend booting from a live distro, then running "badblocks" on the drive to see how many errors it has.
- make sure when you run badblocks you choose the "read" i.e. non-destructive option.


(the chances of it being "another" hardware issue, i.e. motherboard etc, are pretty slim)

If top is showing zero cpu usage, what does "load average" say?
- if this isn't low, it sounds like something crashed in the kernel, in which case you'll need a reboot ..
