Reinstallation

I am now running Fedora Core 6 and it’s really nice.

The installer doesn’t appear to have deleted my Windows installation, and after some fiddling with the graphics driver I have everything back to how it used to be – with extras. Fonts look nicer, the KDE theme is nice and soothing to look at, and lots of things Just Work without me having to spend hours fiddling. I like fiddling with things and learning how they work, but not when it gets in the way of me using my computer for normal things. I can write an X.org config file, but would much rather something did it for me.

I can plug USB storage devices in and they mount themselves properly. Everything is as it should be.

What’s really helped was moving my mail and data onto my server. I can use any computer in my house to access it now. There’s IMAP for mail, LDAP for addresses, SMB or SSH for file sharing and when I turn on the ports in my firewall, remote access to my mail and files.

Now if only I could build a recovery DVD that contained my system at this current moment in time. Having an equivalent of the XP System Restore would be handy too. I managed to break Yum by upgrading things and had to spend an hour undoing the mess. I always thought putting /etc in an SVN repository would be a good idea.

Think back to when you were at school. Wasn’t it great waiting for Christmas to come? Two weeks of guaranteed free time away from school and having to get up at half seven in the morning.

Yes, teachers also think this way. Unfortunately we have to get up at 6:45 and at least look like we’re trying to teach you something. It helps if you pretend to listen, makes the whole thing work a bit better.

Teaching year 7′s about formulae in spreadsheets is quite tricky. The fundamental concept of a formula is totally alien to them. How do you explain to a small kid that even though the cell says “14″, it really contains “=B6*B7″? It makes no sense – they see one thing, but it does something else. The link is hard to make.

I spent most of my first lesson trying not to headbutt the wall or eat my whiteboard rubber. The second lesson was a repeat of the first, with slightly cleaverer children. We got further. Most of the class understood what a formula was and how to make them. Shame the actual objective was to understand how formulae can be used to predict and model data, but there you go.

It’s all good practice. Although I do want to glue some of the kids to their chairs. It is really irritating when they don’t sit on them properly or spin round and round.

And it seems the PSU has died. I probed the laptop end with a multimeter and there was nothing coming out of it. I probed the end of the mains cable and that registered 250v, so the black box in the middle is at fault. It’s definitely at fault now since when plugging it back in there was a loud crack from the PSU.

Well, I found a new one for £25 which isn’t so bad. The machine is also still covered by that PC World warranty they convinced me to buy so I think I’m covered even if the motherboard has died.

And fortunately, my paranoid attitude to taking backups have ensured I’ve not lost any data, and can use my sister’s laptop instead. Mind you, I need to get the off-site backup working properly. I have my really important data stored on a USB pen drive, my server here, my University account and my School account. I’d just like to be able to do the same with the rest of my data.

Lessons have been planned, there are no problems :-)
