Seemingly like everything else in the world, Stack Overflow is getting more & more competitive as time passes. Gaining a good reputation - and even finding good questions to answer - is becoming harder and harder, as more and more people compete for less and less unanswered questions.

This is fantastic if you want to find an answer - but makes it much harder for newcomers to get started and build a reputation on the site.

This guide will help you jump-start your reputation on StackOverflow and help you get more out of the site.

I switched my XFCE machines over to use Compton for window compositing today - and it’s a noticeable improvement.

A compositor glues your stacks of windows together to form the final image that you see on screen. It’s responsible for any fancy effects like drop-shadows, as well drawing windows while dragging, resizing and minimizing or maximizing them. [1]

Compton does this beautifully. It does one thing and it does it well. It provides glassy smooth, tear free compositing and supports a few tasteful effects - drop shadows, fades and transparency.

I stumbled across this while searching for something else and found a great guide in the NeoWin forums [2], where most of this info comes from, so thanks ViperAFK.

Switch off the existing compositor

You’ll need to switch of any existing compositing you’ve got running, otherwise this won …

My wife and I currently live in Canada, and our families are back in the UK. We’d been using Skype to chat with people in the UK, but I was getting frustrated with Skype’s limitations: it either ties you to a computer and WiFi, or running a battery hungry app which slows down your phone. It doesn’t work very well over the 3G phone network here and while it’s free to make Skype to Skype calls, it’s fairly expensive calling real phones. I didn’t really want to buy a dedicated Skype phone - we both already have mobile/cell phones. And, to top it all off, the Skype software for Linux is the poor cousin of the Windows one …

As I mentioned previously, this site was put together using Pelican - a static site generator, written in Python.

Static site generators take your content, pour it into your templates and output the result as static pre-generated HTML, CSS, JS & image files. You can then just upload the resulting folder of output to your server and you’re done. All you need on the server is a web server of some sort, like Apache or Nginx - anything really - all it’s doing is serving static pages.

Ever tried to copy something onto a USB flash drive, only to discover that the file was too big to copy?

This is because most USB Flash drives are formatted using the FAT32[1] filesystem - which only supports individual files up to 4 GB in size, no matter how much free space you’ve got. It also only supports drives up to 2 TB, can’t store symbolic links, can’t store files with these characters in the name: "*/:<>?\| – and is generally pretty crappy.

I recently needed to convert some Apple Lossless music files to FLAC. Here’s how to do it:

If you don’t already have ffmpeg or libav-tools installed, do this:

$ sudo apt-get install libav-tools

Then run this to do the conversion, in the folder with music in:

$ for f in *.m4a; do avconv -i "$f" "${f%.m4a}.flac"; done

And that’s it - it will convert all the .m4a files in that folder to .flac files, preserving the metadata. You can now delete the .m4a files if you want:

$ rm ./*.m4a

The compose key on Linux is incredibly useful, but not configured by default - and on XFCE there’s currently no graphical UI to change it. However, it’s pretty simple to change…​ here’s how to make the Caps Lock key your compose key:

In the file /etc/default/keyboard, change XKBOPTIONS to look like this:

XKBOPTIONS="compose:caps"

Save the file. You can now either reboot, restart X, or see Activating your change without rebooting, below.

If you don’t want to use Caps Lock as your compose key, there are some other options to choose from in this file: /usr/share/X11/xkb/rules/xorg.lst - search for ‘compose’, they’re listed towards the …

I’ve been meaning to consolidate my personal websites onto this domain for a long, long time. My original personal website, dflock.co.uk, started in the late nineties - and has been getting a bit long in the tooth of late.

That site has been up, looking mostly like that, for ~15 years - with zero maintenance or downtime. Nice to know it’s still valid CSS 1.0 :)

When I created that site originally, the options were either Adobe PageMill, or hand editing HTML in a text editor. I’ve never been a fan of WYSIWYG (what-you-see-is(supposedly)-what-you-get) editors - and the early ones were…​ not good, so I wrote all the HTML code by hand.

That site also has some data heavy pages, which are manually published from …
