Command Line Software Management

December 2, 2009 One comment

One of the nice things about a Debian-based Linux distribution is that it is easy to pull a piece of software onto your system from a repository using either apt-get or aptitude. Some may prefer to have a GUI but I find that the command line offers certain extra transparency that stops the “what’s it doing?” type of question. that’s never to say that the GUI-based approach hasn’t a place and I only go using it when seeking out a piece of software without knowing its aptitude-ready name. Interestingly, there are signs that Canonical may be playing with the idea of making Ubuntu’s Software Centre a full application management tool with updates and upgrades getting added to the current searching, installation and removal facilities. That well may be but it’s going to take a lot of effort to get me away from the command line altogether.

Fedora and openSUSE have their software management commands too in the shape of yum and zypper, respectively. The recent flurry of new operating system releases has had me experimenting with both of those distros on a real test machine. As might be expected, the usual battery of installation, removal and update activities are well served and I have been playing with software searching using yum too. What has yet to mature is in-situ distribution upgrading à la Ubuntu. In principle, it is possible but I got a black screen when I tried moving from openSUSE 11.1 to 11.2 within VirtualBox using instructions on the openSUSE website. Not wanting to wait, I reached for a Live CD instead and that worked a treat on both virtual and real machines. Being in an experiment turn of mind, I attempted the same to get from Fedora 11 to the beta release of its version 12. A spot of repository trouble got me using a Live CD in its place. You can perform an in-situ upgrade from a full Fedora DVD but the only option is system replacement when you have a Live CD. Once installation is out of the way, YAST can be ignored in favour of zypper and yum is good enough that Fedora’s GUI-using alternative can be ignored. It’s nice to see good transparent ideas taking hold elsewhere and may make migration between distros much easier too.

A case of double vision?

November 4, 2009 No comments

One of the early signs that I noticed after upgrading my main PC to Ubuntu 9.10 was a warning regarding the health of one of my hard disks. Others have reported that this can be triggered by the least bit of roughness in a SMART profile but that’s not how it was for me. The PATA disk that has hosted my Ubuntu installation since the move away from Windows had a few bad sectors but no adverse warning. It was a 320 GB Western Digital SATA drive that was raising alarm bells with its 200 bad sectors.

The conveyor of this news was Palimpsest (not sure how it got that name even when I read the Wikipedia entry) and that is part of the subject of this post. Some have been irritated by its disk health warnings but it’s easy to make them go away by turning off Disk Notifications in the dialogue that going to System > Preferences > Startup Applications will bring up for you. To fire up Palimpsest itself, there’s always the command line but you’ll find it at System > Administration > Disk Utility too. My complaint about it is that I see the same hard drive listed in there more than once and it takes some finding to separate the real entries from the “bogus” ones. Whether this is because Ubuntu has seen my SATA drives with SIL RAID mappings (for the record, I have no array set up) or not is an open question but it’s one that needs continued investigation and I already have had a go with the dmraid command. Even GParted shows both the original /dev/sd* type addressing and the /dev/mapper/sil_* equivalent with the latter being the one with which you need to work (Ubuntu now lives on a partition on one of the SATA drives which is why I noticed this). All in all, it looks less than tidy so additional interrogation is in order, especially when I have no recollection of 9.04 doing anything of the sort.

Sometimes, things do get missed…

Being a user of Textpattern, I should have a vested interested in any developments in that venerable web platform. However, the latest release came out at the end of August unbeknownst to me and that’s with an entry on the Dev Blog. Those blog entries come irregularly so that might have been how I missed it but there were other things going on in my life like the installation of new windows in my house and weekends spent in Scotland and Ireland.

Still, the whole release was more low key than, say, a new version of WordPress where many would be shouting how important the upgrade would be and with messages turning up on blog administration screens too. There may be good reason for this given the recent problems experienced by those who fail to keep up with progress. Of course, WordPress is a major target for unwanted attention so it’s best to keep your wits about you. The low key nature of Textpattern might be an asset when it comes to warding off miscreants and its greater compatibility with more technically minded folk may help security too. Saying all of that may be pure speculation but you only have to look at the world of operating systems to see how the idea came into my mind.

A later posting on the Txp blog tells you about the new goodies available in release 4.2.0 but here’s a short selection to whet your appetite: themes for the administration area, multiple sites and new tags. Upgrading proved painless though I did try it out on an offline version of the microsite where I use Textpattern before making a move on its online counterpart. All went smoothly but it’s alway best to look before you leap or a site rebuild might be in order and no one needs that.
