On Tuesday, the latest version of Fedora came out which includes the usual round-up of new updates for several purposes, which can be read http://docs.fedoraproject.org/release-notes/f10/en_US/index.html#sn-Fedora_10_overview

I use a Fedora 9 server, which I can’t get to, so the normal method of putting a disc in and letting anaconda do all the work just isn’t suitable for me, so using yum I “upgraded” by telling yum to use the Fedora 10 repos and then getting the system to update from this. This method is somewhat risky, but for this case it seemed to turn out well. Previously this method has caused funny problems with X-server, but as I don’t use any x applications (everything is just command line for me) this wasnt an issue.

The steps I used to set up this system was as follows.

  1. Firstly, make sure your Fedora 9 installation is as up to date as possible. This is done in the normal way, and for this, it is probabily best if you clear your cache of any repos.
    yum clean all && yum update && yum clean all

    You will notice I clear the repo cache twice, this is to make sure that when we get it to do the upgrade, it doesnt try to use any old F9 repos.

  2. Remove any extra repos other than the default Fedora ones, to minimise package conflicts even further. These files can be found in /etc/yum.repos.d/
  3. Run the following command into rpm to get fedora to believe it is Fedora 10 and then to update itself to it:
    rpm -Uhv http://www.mirrorservice.org/sites/download.fedora.redhat.com/pub/fedora/linux/releases/10/Fedora/i386/os/Packages/fedora-release-10-1.noarch.rpm http://www.mirrorservice.org/sites/download.fedora.redhat.com/pub/fedora/linux/releases/10/Fedora/i386/os/Packages/fedora-release-notes-10.0.0.1.noarch.rpm
  4. Run another yum update, this time it will download a lot of packages as this will now upgrade you to Fedora 10
  5. Reboot using the reboot command
  6. Pray (a little)
  7. Say hello to Fedora 10

You should now be running a proper version of Fedora 10. Note however that using an installation disc and upgrading using anaconda is still the recommended method of upgrading, but for those that cannot do that, at least this offers an alternative.

Note however that due to to some changes that happen between versions, you might notice some slight bugs running a new version upgraded in this way. I have yet to see any of these probems, but that is not to say that there aren’t any. Problems that are found will have to be fixed some other way, and I cannot be held responsible for any of these. Basically, here is a method but it is unsupported so it’s at your own risk.

I hope these instructions will come in handy to someone at some point, but basically if you need them, they are here.

Now it’s about time for some real content. Presenting the first publicly visible project, the VAT Converter! Inspired by the need to convert prices from the old 17.5% VAT standard over here in the UK to the new 15%, I wrote a little script to do this for you. I will at some point release the code behind this script after I have deceided on a licence for it (probabily some CC licence), but hey, its content on here right!

The URL to play with the converter is http://www.spcook.co.uk/projects/vat1715/

For those of you who broke it, or want to suggest improvements, the Project Forum is available at http://www.spcook.co.uk/forum/forum/vat-converter

 

I hope you enjoy this, and possibly find a good quick use for it.

Here goes nothing, a nice new plugin for my blog so I can highlight code… let’s see if it works:

#include <stdio.h>
 
int main(void){
  printf("Hello World\n");
}

Yup, that seems to work :D

Just got this update literally a minute ago, and it confused me… what the hell, my gmail looks different. It appears theres now themes built into it, which seem to be just like iGoogle themes. There are 31 themes at the moment, and I have screenshotted a few for you here:

Right now I am using the Planets theme, its offering me quite a good mix of image and transparency, though I think I may settle on the Shiny theme or some other theme that resembes a normal Google blank page.

Anyone else seeing this at all? To see, go to your Gmail settings page, and look for the “Themes” tab.

 

Edit: This is only showing on my Gmail account, not my Google Apps account at the moment, so it appears its a gradual rollout (I have give me beta stuff turned on in Apps)

Let’s write something marginally interesting then shall we. Last Wednesday I went to play a couple of hours of Laser Question with some of the CSS. This was probabily the best time that I have had in a long time. I haven’t really got my score cards with me at the moment, but from memory I have gotten alot better as I have progressed.

I think it was this: 55, 109, 155, 243 (give ±20 in the latter two). Not bad for my first time playing, and not as Si, no, I must represent Techious so my name was TCHS in the games. Oh yes, and not last for any of the games! (First one last bar one, but meh, I still like).

 

In other news, I gave a really bad presentation embarasing Techious for all it’s worth, well I needed to give a presentation on something technical I’d done. Technical, umm Techious yes that works! Anyway I’ll try attaching it as a PDF to see if this system allows it.

Coding is becoming more interesting, I’m currently writing an over the top method for my latest coursework, I’m sure theres easier methods, just mine works for lols!

This is about it

Now, I’ve finally fixed the problem (sort of, it publishes half the time but it should work now) but this now means that a month of blogging has come back to life.

Enjoy the comment spam Skillers ;)

Now really, this is really stupid. Personally, I think that people who do this should be banned from driving for ages, not that that will stop them. Some people just don’t care.

A £10,000 new car?!?!? What the fuck?!?! Why on earth would someone be that stupid? I mean come on, if I had a new car like that I wouldn’t mistreat it like that at all. Going to Bristol Magistrates now, I really think that is when you know that you are in some shit. Well, at least it’s close to the University, driving better not be an option to get there, someone else should drive there.

It’s also on the front page of the Epigram (not suprisingly), theres the link:

I’m not going to comment much more on this but hey, doesn’t show our Uni in too good a light now does it :(

Now really, this is something that could be taking the metaphorical piss, exam today. We had three hours to do it in, and it was well, done in about 20 minutes, and half an hour in the room was half empty. Now exams that easy, worry me a little, because it’s almost like something has been overlooked, but I would be really suprised if something has been overlooked, but hopefully I should get my results within about a week so that should be good :)
