If you have more than one computer running Ubuntu (or Debian), or maybe you are experimenting with different installations of Ubuntu using something like VirtualBox, you might find yourself using a lot of bandwidth and time when downloading packages from the Internet to update or add capabilities to your machine. By default each installation of Ubuntu will go directly to the Ubuntu download servers to get packages, producing a situation where you are downloading the same file multiple times through your connection to your ISP. There is an alternative to this situation though, you can download the packages through a host on your own network that will act as a cache. The next time any machine wanting that file requires it, the cache will serve its own copy, instead of having to download it again. This is a lot quicker, as the speed in your internal network will be much higher than the speed of the connection to your ISP, it is also a great bonus if you have maximum download allowances as part of your Internet connectivity package. Setting this up is not too difficult, thanks to a program called Apt-cacher.

For about the last year I have abandoned the use of my workplace calendar system (based on Microsoft Outlook and Exchange) and using paper diaries in favour of Google Calendar. This solution offers a number of advantages for me, it is entirely web based, it is platform independent and I can even see my appointments on my mobile phone thanks to the mobile version. I've also been using Mozilla Thunderbird, an excellent open source email program, for years. So it was very interesting to read Rob Parsons' post on getting these two technologies working together through a couple of add ons. It looks like Mozilla Thunderbird could become the Personal Information Manager of choice for those who use Web 2.0 services to manage their affairs thanks to an increasing number of addons. On the horizon is also an add on to integrate it with the popular web based task management system Remember the Milk, and apparently it is already possible to integrate Thunderbird with Google Mail.

The idea of PlanetOU was always to represent a community around an institution by aggregating blogs written by people connected to it (the idea is explained in full in my earlier post What planet are you from? PlanetOU of course!). It uses the core Aggregator module in Drupal to pull in content from about fifty different websites to make a constant stream view of the latest blog posts from OU staff bloggers. This approach works well, but a key point to note here is that when feed items are imported in this way Drupal does not create new node items (it isn't native content to the software that runs this site), and as such are not visible to the built-in search engine. These blogs are spread across many different domains (e.g. only a few people on the TwitterLeague for OU people use the OU's blogging facilities) and so are not indexed by any institutional search engine. Fortunately there is now a solution to this challenge; a Google Custom Search Engine (Google CSE).

Thanks to a fellow user of Twitter I was alerted to this great video on YouTube which is a presentation by Michael Wesch who is Assistant Professor of Cultural Anthropology at Kansas State University, given at the Library of Congress back in June 2008 which is all about YouTube and the community that uses it. Admittedly, when I first saw the title I wasn't encouraged really, I thought it might be a rather dry, navel-gazing study of the community surrounding YouTube, reading too much meaning into what is happening there, maybe with slow death by Powerpoint. I was very wrong, this video is well worth watching, and all 55 minutes of it too. It is thought provoking and even moving in places, with plenty of facts and figures that make fascinating viewing.

If you own an Asus EEE PC or another machine running Ubuntu and a camera which is only supported under Video4Linux 2 (V4L2) you will have noticed that it not possible to get your camera to work under Flash. This will hopefully change soon, with V4L2 support in Flash 10. However, as Flash 10 is still a release candidate you might find that you still have problems when using a V4L2 camera. I've seen this on websites that switch the camera off and on again during one Flash session, this seems to not work very well. There is another way to get the camera working under Flash though, the Flashcam project which gets around the lack of support for V4L2 webcams by forwarding the output of the camera to a simulation of device that uses Video4Linux 1, which is supported under Flash 9.

No doubt the big tech story of the week has been the release of the new Google Chrome browser, Google's new entrant into the browser wars. Like many others I downloaded this and gave it a go to see what the fuss was about. So first gripe, the current beta is only for Windows, although we are being promised versions for Linux and the Mac. This is an interesting decision, maybe it was taken as they don't want to aim the product at "geeks"? However, as an old manager of mine used to say, let's "park that thought" for the moment and look at the browser itself. Google came up with a great way to explain their new browser and its features; they did this in the form of a comic book and this can been seen at: http://www.google.com/googlebooks/chrome/. I'm not really into comics or graphical novels, but this made a refreshing change from a white paper or a powerpoint-type presentation, although I must admit my attention was starting to stray at the end! This is well worth reading as it explains the whole project and its features very well.

A few days ago Lifehacker Australia carried a blog post where they said that they felt my method to get the Huawei E169G modem working on an EEE PC was a "tad fiddly". Well, they are probably right, so taking this as a challenge I've had a go at creating a package that will apply these steps automatically and make getting this modem up and running as simple as possible. This is one of my first attempts at packaging, so there might be some problems, however I've successfully tested that it works on both a Xandros and an Ubuntu powered EEE PC. The package is quite basic in what it does, so it may well work on some other Debian-based distributions too.

Having Flash 10 on your EEE PC opens up some interesting possibilities. One of these is the use of Seesmic, a website currently in beta that is designed to allow people to have conversations via video. The idea of this is that people can just use the built in webcam of their computer to record a short dialogue, this can be much quicker for somebody to do than composing a written comment and possibly could speed up the flow of a web-based discussion. The problem for EEE users is that this site just isn't designed for this type of machine. Hopefully the rise of netbooks means that we will see less and less sites being developed that do not work on them (that would be sensible after all) and let's hope that Seesmic will be able to correct this problem once they are out of beta. The way that the site is currently set up means that it is not possible to use it with an EEE. However, this is not the end of the story, open source has a habit of providing amazing flexibility, and we can put this to good use to make this site work for us. You mileage may vary with what is written here, but I have had seesmic working on an Ubuntu-powered EEE. If you get this to work with a standard EEE let me know.

It's been a long journey to get full Adobe Flash player functionality on Linux machines, but now it looks like that journey is drawing to a close. I've just been playing with a release candidate of Flash Player 10 on my Asus EEE PC and am very happy with the results. It looks like the built in camera will now work under Flash Player, thanks to the addition of support for the Video4Linux Version 2 camera API, which is great news if you use applications that make use of this functionality. The other very noticable change is that full screen video now appears to be working at the correct frame rate making it possible to enjoy full screen videos from such YouTube or BBC iPlayer without the choppiness caused by a slow frame rate. This turns the EEE into a great portable net media player (although be very careful using iPlayer and video sites with a mobile internet dongle or you may end up with a hefty bill!).

Back in December 2007 I installed SecondLife on a factory-standard Asus EEE PC to see if it would work or not, it did, even with just 512MB memory installed, but it was a little slow. So since adding a bit of extra power to my EEE by upgrading it to 2GB RAM and installing Ubuntu on it, I was curious to see how this might improve the experience. The SecondLife client has also been updated recently, the version I tested with is version 1.20.15.92456 which I downloaded directly from the SecondLife web site. The results were pleasing, the client was usable, the graphics more vibrant and details than before, as you can see from the picture, even with low graphic detail selected the detail was quite impressive.
