For the past few weeks life has been busy, and when I say busy I mean hectic beyond belief. In that time I’ve had a few OSS revelations I’d like to share.

As an experiment at work I thought I’d try using eclipse as an IDE instead of my normal vim+terminator job. Scary as it is, I find myself actually quite liking eclipse. It may be that my work machine has 4GB of RAM, and so copes better than the machines I’ve used in the past, or it may be that I’m starting to lose my qualms about what tools I use to do a job, as long as a job gets done. The PHP and Python tools inside eclipse have made my life a lot easier, and I really do find little things, like it reading out the docstring I’d put in a function when I hover over that function when it’s called, useful. Has eclipse evolved to where it’s useable or has affordable technology caught up with eclipse? A bit of a quandry for me that one.

The other small revelation I’ve had recently is that KDE4 is now inherently useable, and quite shiny to boot. when I’ve tried it in the past I quickly got fed up with things that didn’t quite fit or where missing completely, but now time has passed, and like KDE4 I believe I’ve changed a bit, and actually quite like it. I won’t be using it at home for a while, as the 7″ screen on this tiny little netbook certainly won’t make it very use-able compared to the  20″ odd monitor I have at work. The one big thing annoying me with it at the moment though is that konquerer doesn’t seem to fit with the default theme. Niggly annoyance I know, but surely that should be a papercut?

The last revelation I’ve had, though it’s not really a revelation, is a pang of guilt. I’m inherently a consumer in the whole Linux ecosphere. I consume by far more than I give back, and at the moment I simply don’t have the time to give back as much as I’d like. So this is my decree, and a proclamation that as of next year (with certain exceptions) I intend to deem one night a week free software night. On that night I will help to squish bugs, I’ll sit on IRC and be patient with people trying to help them through problems, I shall try and get involved in the various mailing list debates I sit and read, and I shall attempt to stop consuming quite so much and start giving back as much as I can.

In order to do this I will need a little help. The whole software workflow thing is a bit of a mystery to me. I’ve had little formal training in such things and as such tend to wing it more than I’d like. Can people point me in the direction of some good literature to help mend this? I’m quite willing to get my hands dirty if people are willing to be patient with me as I learn how the OSS developer crowd works so I can learn and adjust. In a way I’m hoping that this will flow back and help me at work as much as it’ll help me contribute back to the community in general.

If anyone also has a project they might want a hand with one evening a week from the of the month, feel free to drop me a line by your favourite communications method

My knowledge of linux is sadly lacking, but every day I improve on it. Since I had a few days free over the easter holidays I thought I’d try and improve this further by installing Linux From Scratch. This is essentially building up a linux system from it’s base packages and takes a LONG time. This to me seemed like a good idea, it would exponentially increase my knowledge of what makes linux tick, and what depends on what.

I started on Monday night by reading through all of the LFS documentation. As bedtime reading goes, it’s actually quite interesting, and it seemed like a good idea to get an overview of what needs doing before I started.

Luckily for me my laptop has a fairly large HD (320GB) so finding some space on a partition was quite easy. A quick boot into a livecd and resizing my /home partition created a nice little 10GB partition for LFS to go in. That was at 9am in the morning. By 10:00am I had downloaded all the required programs in the mounted partition as directed by the book and started to build them.  In the first day, I managed to build the initial toolchain and got into the chroot and got to chapter 6.15 in the LFS PDF. The longest thing to build was probably either glibc or GCC, which took just over an hour, but did give me time to cook some tortillas from scratch for lunch

The second day, it took me from about 10 in the morning till roughly 3 in the afternoon to finish installing everything.  Was a bit quicker than I expected, but also a lot more involved.

I did hit a few roadbumps, I didn’t have gawk installed on the host system, so at one point something didn’t compile properly and freaked out a bit. A simple sudo aptitude install gawk fixed that though. When I was recompiling glibc all of the tests failed, it took me a few minutes to realise that the reason this was happening was because I’d forgotten to run “make”.. oops.

The last major bump was that when I chose which options to compile with the kernel, I forgot to add the drivers for my ethernet card and my wireless card, so when I booted the machine I had no network! A quick scan through the options and a recompile sorted that out (to include the b44 driver)

What have I learnt from this? Two things mainly.

1. Where everything should live on a linux system and why its there
2. Package Managers are beyond fantastic. They save so much time and hassle!

Tomorrow I intend to try and make my LFS install useful by installing openssh initially, wget and possible x.org and gnome. That may be a bit ambitious at the moment though!
