In ubuntu/debian linux software installs, there are such things as “metapackages” which is a package that just describes what OTHER packages it “needs”. For instance in ubuntu, the kubuntu-desktop package is just such a package – when choosing it, it installs everything necessary for the kubuntu desktop/customizations to install. So, I was hit with an idea while I was apt-getting 30-40 odd packages…. everytime I “provision” a new ubuntu system I have a list of packages that I want to make sure are installed, why don’t I just create a single metapackage and be done with it to make life simpler…. But how could I do this?

Clonezilla
For quite a while I’ve used ghost4linux (g4l) for my disc cloning needs. What I REALLY like are the ability to do a network copy of the image to an ftp server and the built in dd_rescue to rescue data from a failing hard drive. Unfrotunately g4l does a bit by bit copy of a drive which means it can take a while and it copies the full drive capacity (say for instance 80GB) even if you only have 5GB worth of information. Now, it can be compressed and if you massage the drive by defraging/filling empty space with ones before you start you can squeeze the image down pretty small, but… sometimes that’s a big task (I remember leaving one box writing zeros to the drive overnight to prepare the empty space for a g4l cloning.) Anyway…. I’ve run across clonezilla recently and am VERY impressed – it’s basically a wrapper around partimage – it will only copy the data component of a disc’s contents if it recognizes the filesystem (most linux filesystem types ext2/3/reiser plus ntfs and fat… it seems like a couple others too.) If it doesn’t recognize the filesystem it drops back to bit by bit mode which is nice. The only other thing I would want from it is better documentation and dd_rescue capabilities. (And maybe a fuse module to be able to image to/from ftp servers.) It supports several network approaches (samba/ssh) for writing/reading images over a network.

Custom livecd’s, virtualbox, seamlessrdp and sata dvd burners…
I thought this writeup was interesting on the idea of using a web interface to customize a livecd. I’ve built a couple livecd’s (that I still use) for tech support, but I’m always thinking of one more tool that I’d like to have. After looking through their wizard it seems a bit limited in the granularity of what can be chosen (at least for what I’m thinking of.) But… it might introduce a new interest in the use of livecds.

Ubuntu Gutsy Gibbon coming
The release date for the 7.10 Ubuntu release is coming soon. I’ve installed a beta into a virtual machine to see what’s what and so far haven’t had much time to play around. I seem to recall the localization question being new in the installer, but then it’s been a while since I used the ubiquity installer (used the alternative install to setup software raid based systems.) But… other than that I haven’t poked around with it much. However, I have read that the 8.04 (April 2008) release will be codenamed Hardy Heron and will be a long term service (LTS) version. I’m MORE interested in that given that I have one server running the previous LTS release 6.06 dapper drake. I’ll be interested in upgrading it to a newer LTS EVENTUALLY, but I don’t know if I’ll jump for the upcoming April release or wait… but I did find some promising instructions for upgrading to Fiesty (7.04). It’s good to see that kind of detailed how-to as opposed to just an upgrade option on the cd so you can do it from within the OS.

Windows web editor
I’ve been looking for a simple windows based web editor to recommend for someone. I use quanta plus on linux and would really have a hard time LEAVING it, but… there’s of course dreamweaver and frontpage… but I’ve also found kompozer which is based on nvu – although I still REALLY wish quanta plus were available for windows. (Of course, if they want the nice toys, maybe they should just think about switching or dual booting…) I’ll leave comments on in case anybody knows of a good windows based, web editor that has some of the similar capabilities of quanta plus.

Torbutton – firefox anonymity browser extension
I don’t know if anonymity is exactly acheived, but…. anyway not too long ago I explored/setup tor on my system to play around with, no real reason I suppose, but doing what I do it pays to be aware of many different kinds of software. Tor proxies web requests from your machine through a tunnel to another machine on the tor network – it could be nearby or far away, but it essentially prevents the destination site from knowing EXACTLY where you’re located and can prevent machines in the middle from logging your access (i.e. your isp, or a wireless access point owner.) The problem is – once it’s setup you have to turn it on by changing the proxy settings in your browser – tedious. Well, in comes torbutton, which is a firefox extension to enable routing through tor with the click of a mouse. (You do have to have it setup beforehand (tor and privoxy work well together for that.)

Miro – rss/videocast aggregator/player
I’ve just been using miro the last few days and I ought to mention it here. It’s a multiplatform program (windows/ mac/ linux) that let’s you subscribe to video feeds (much like a podcast catcher does for audio.) It also plays video within the player (you can organize your local video clips through it as well.) You can also search/download from youtube/etc. and you can add custom rss feeds such as those from tvrss.net for instance. It’s also bittorrent aware, so it can make use of bittorrent for downloading.

Web translation
I found this link of plugins for wordpress to aid in multilingual site building. I’ve been experimenting with English/Spanish designs of one site I maintain using plain html (index.html.en index.html.es and the server gives the correct page depending on the browser localization. It seems as though there was an .htaccess change that I had to make as well although I don’t recall off the top of my head. (Maybe I can update if I read through it again.)

Stopping email hoaxes and chain emails…
How many times have I seen the same chain email about who knows what… it always ends in something along the lines of “I don’t know if this is true, but I figure I don’t have anything to lose, so pass it along and let’s see what happens.” Computers were supposed to improve productivity, sometimes I think they’ve fueled other things though…. breakthechain.org is a good site to refer people to that forward messages to you that may be hoaxes or chains… some of them are real, some are hoaxes, some are absurd but why do we keep emailing them back and forth? Try to get some of your time back by sending folks to breakthechain.org

Residential VOIP
Of course, we’ve heard of skype, vonage, and our dsl/cable providers hawking VOIP. I thought I’d make a note of this one though as the name is a bit more obscure… packet8
