using Python to model complex
simulations. Due to faulty partitions,
Rob has been unable to shift the

out of JRPG mode and he is now
trapped in the sky, dressed as Cid.
His LVM research (p.46) was thrown
overboard and delivered by chocobo.

Welcome to the latest issue of Linux User &
Developer, the UK and America’s favourite Linux
and open source magazine.
There’s still a lot of buzz about the Raspberry
Pi 2 and we’re starting to see the next generation
of projects emerge, taking advantage of the new
processing power to achieve more than ever before.
Here at the Flying Fortress, however, we still think some of the
best projects are the hardware hacks that tear up old, broken
devices and turn them into something new and exciting. So we
went out and spoke to the makers behind some of the best –
find out how you can put a spaceship in your kid’s bedroom,
upcycle old TVs and radios, build an alarm clock that’ll keep
you on your toes and more, all starting on page 18.
This month we’re welcoming more Linux experts aboard,
too. Alexander Tolstoy takes us through the Qt5 applications
stack from page 54, while Anna Kobylinska and Filipe Martins
get us started with virtual Linux instances from page 58. Plus,
you can join Mihalis Tsoukalos in his brand new coding column
on page 13, where each issue he will be teaching us essential
skills for solving coding problems with algorithms. We also
have a guest column this issue from code quality experts
Coverity, which you can find on page 14. To see what else is in
store for you this issue, just flip the page – enjoy your mag!

RichardSmedley
started using computers long
before WYSIWYG and still maintains
that the command line, and Emacs,
is the most productive working
environment. This month Richard
explains how to troubleshoot and
repair your network connections
(p.30) and picks out the best tabbed
terminal emulators (p.77).
Mihalis Tsoukalos
is a UNIX system
administrator with expertise in
programming, databases and
maths. He has been using Linux
since 1993. Mihalis follows Richard’s
networks feature with a closer
look at netstat in this issue (p.50),
and also begins his new column on
coding and problem solving (p.13).
AlexanderTolstoy
has used Linux for years.
Though brevity is the soul of wit,
Alexander loves writing on desktop
Linux in details. He has been doing
it since he installed his first distro
from a floppy disk. In his first
LU&D
tutorial, Alexander shows us how to
customise and improve a basic LXQt
desktop with better Qt apps (p.54).
Gareth Halfacree
is our resident news
reporter and brings us the latest
developments from all over the
open source world, starting over
on page 8. This month, Gareth
also tests the long-awaited Intel
Edison module and its companion
breakout board to see how much
has changed since CEX (p.82).
