Git pull stopped working

by

So this is a weird one. I'd previously grabbed some code from a git repository. But recently when I went to update it, I got an error fatal: unable to connect to github.com:github.com[0: 140.82.118.4]: errno=Connection refusedgithub.com[1: 140.82.118.3]: errno=Connection refused Uh-oh. Thinking it might be a transient error, I left it for a while. But then … Read more

Gimp 2.8 Resynthesizer Plugin Ubuntu 18.

by

Seems like this plugin changes the rules ever so often. This is what worked for me today.  Remove old plugins from ~/.gimp2.8/plug-ins/ Get the latest code from https://github.com/bootchk/resynthesizer.git git clone https://github.com/bootchk/resynthesizer.git Install dependencies and compile code. ./configure doesn't work as suggested, so I just ran the .autogen script, which did.  sudo apt install libglib2.0-dev libgimp2.0-dev automake intltool./autogen.sh makesudo … Read more

Counting files in subdirectories.

by

ze countOK, it sounds simple, and it probably is if you're sitting at your desktop with Gnome or KDE fired up. However if you're looking on a server half way across the world, using the command line its not so easy.

There are a number of tools which are useful in finding out things about your filesystem. ls, du, df are three of them, but sometimes they just don't give you the information you need. In my case I'm backing up a server to a remote location. The script was timing out becase I was trying to back up too many files at once, so I needed to find the number of files in each subdirectory.

Linux Memory Usage Summary Script

by

I was having trouble with a webserver this week, which I'd just set up for a client. When it went live, it seemed OK initially, but when we left it overnight it curled up its toes and died. It was so dead that I couldn't even ssh in to reboot it, so we had to do a remote reboot. Crunch.

Anyway, on getting it back up, I poked around in the logs and found that it was running out of memory, which it really shouldn't do given that it was a fairly low load on the webserver, and only apache, mysql and php were running on it. I looked around the Interwebs and found an excellent resource called Troubleshooting Memory Usage, which gave me some pointers about how to rein in apache and stop it from eating up memory so quickly. Thanks!

Anyway on the page was a script for summarising memory usage, which I thought was a good idea, so i grabbed that one and adapted it to my own purposes. I thought I'd make the results available here, so feel free to grab it and adapt it to your own needs.
