aDeskbar!

my desktop with aDeskbar on the right

I should have posted this earlier, but... well, anyway. aDeskbar is a perfect solution for those of us who are really Mac users but have migrated to linux for whatever reason (I use linux at work mostly). As you can see from the screenshot it can sit anywhere you want it to, it can autohide, and it works seamlessly and trouble-free with the lightweight distros out there (in this case, Peppermint-ice). If you are interested, read the original post on OMGubuntu and download the deb file by following the links. I'm finding aDeskbar a valuable utility at the moment. Enjoy. The link:

A quick meerkat (Lubuntu 10.10)

As you know, I'm using a minimum-ram laptop at work so the full-blown-bells-and-whistles (read bloated) OS-es are not really an option for me right now, especially as it's the desktop environment that typically hogs the available RAM.

Peppermint's two flavours -- Standard and Ice -- are great, as is Jolicloud 1.0. To these I can now add Light Ubuntu (Lubuntu). Lubuntu is another LXDE environment (the Peppermints are too) with Openbox but the newest release is built upon Ubuntu's meerkat (10.10) whereas the Peppermints are using lucid (10.04).

Lubuntu 10.10 is fast, attractive, and pretty much ideal once you've installed it and added a few tweaks. Since I always use more than one partition on my machines, I encountered a GRUB problem after installing Lubuntu in that I could access other OS-es but not boot from them. The problem was that Lubuntu doesn't install osprober so the startup sequence doesn't see the other partitions. The way to fix this is simple, however. Open a terminal, type

sudo apt-get install os-prober then
update-grub

and the other systems will be available to select from at the next reboot.

The other tweak is to download a new lubuntu add-on, lubuntu-control-center_0.2_all.deb which is available from the web: http://www.mediafire.com/?3kyy21ubztiki0c. This gives you a gui that you can use to modify much of lubuntu's interface.


But there's more:

If you like Peppermint Ice's respin cursors, you can get them from synaptic -- search for dmz-cursors, download and restart.

An easy way to get a terminal is to add (again through synaptic) a little app called guake, which allows you to utilise F12 for this purpose. I've found it very handy.

There's no need for Peppermint's Ice web-app creator, since Lubuntu comes with Chromium as default and you can create your own web-apps by going to a site with the browser, selecting tools, create application shortcuts, and saving the new app directly into your Applications menu.

And, of course, if you choose to add Firefox (not installed with Lubuntu) remember to add my Sifundzani1 Firefox Persona!

Overall, I like the new Lubuntu; and I think its menu behaviour is actually better than Peppermint's at this point. It's also of course very fast.

Ice prevents freezing!

Although I have a variety of computers, I mostly use three: a Macbook, a Samsung NC10, and a generic laptop that comes with my office at work. I use the generic laptop a lot, especially since I maintain a LAN in the school's admin block. But it came with only 200+ MB of RAM. Needless to say, the new releases of Ubuntu and OpenSUSE hardly get out of their starting blocks on this machine.

Enter Peppermint and especially Peppermint Ice! Instead of waiting, with mounting frustration, for the bigger distros to actually do something on this machine I can actually do my work through Peppermint without hassles. I prefer Ice since it's browser back-end is Chromium rather than Mozilla, and I also think it's slightly faster. Printing doesn't come with Ice initially but CUPS is easy to install via synaptic. All-in-all, I'm a fan.

Ruby Shoes!

Everyone knows of course (or should!) about Dorothy's famous ruby slippers in The Wizard of Oz:

they are justly iconic.








But have you seen this icon before?

These are also ruby shoes! 

Let me explain. From time-to-time I do some coding/programming, since I began using computers in the days when computers came with built-in programming languages; in those far-off days the only way you could have a program is if you wrote one (my first computer was a ZX-80, R50 at the time from South Africa). The languages I learnt back then were BASIC, LOGO, and PASCAL. Later on, I actually posted a few programs online for Mac OS 7,8, and 9. 

Well, recently I've been tinkering with PYTHON and RUBY. RUBY... aha! RUBY is quite special I think.

It got me considering how I might be able to teach some RUBY at school to the students. Surfing the net I came across SHOES, which is a mini-GUI kit for RUBY. When students start learning something they want to see quick results, and SHOES certainly provides quick results. Like RUBY itself beginners can see results from the get-go. I think it might be what educators are looking for. And it's not even difficult to get hold of. It's already in the Ubuntu/Mint/Peppermint repositories, works as call-to app, and (obviously) runs on ruby. More on this next week...
