tXt (also known as GroupSMS) is a mobile chat service that enables a subscribers to quickly send the same message to several members of a group from a single SMS, instead of having to manually resend the same message to all the members of a given group. It can be used in the various group scenarios such as a family, bible study groups, and golfing buddies, just to name a few.

Ok, bible study groups, *g*. I think it is great that Safaricom provides such a service that can be managed via SMS. But on the other hand, there are some drawbacks. They charge 10KSH per SMS.

Twitter seems to be good alternative to me instead. Since some weeks I have put up a network with family and friends from Kenya and Germany. Via Twitter it is possible to receive 250 SMS per week at no charge. Messages can be sent via SMS (at your normal SMS rates), Web or Messenger. Twitter does not depend solely on SMS. It can be managed via website or Instant Messenger as well. They also offer a handy mobile site that can be found on m.twitter.com. All you need is to put up an account for yourself and friends and start following each others “tweets”. The only function I am missing at Twitter is the possibility to put up your own groups within the people that follow your tweets - e.g. “bible study”, family or co-workers.

Jaiku is a similar service that also offers SMS, but not to the extend of Twitter. Good thing are their group-channels. I’m not quite sure why Jaiku isn’t as pupular as twitter, but maybe just because twitter came first. Safaricom’s tXt might be a real good thing for exchanging few information within a small group once in a while. Group-size is restricted to only ten participants, so this limits use e.g. as one way information channel for large groups. In case you need something of that kind, be sure to give Twitter or Jaiku a try. What I could not find on Twitter is a way to put up accounts solely by SMS. It is possible to invite friends from an existing account via SMS though. A quite extensive introduction to twitter can be found on Caroline Middlebrook’s weblog.

Here is the Twitter-FAQ answering most of your possible questions. This are the commands you can use via SMS or Messenger provided on twitter.com:

Twitter Lingo

Send these commands to +44 762 4801423 or over IM and interact with Twitter on your mobile phone or chat window!

Inviting or Adding People

• invite +49 454 784564 john sends a text invite to john (use the full number including the country code)

Talking To Friends

• To update your own Twitter timeline just text or IM whatever is on your mind.

I guess if Safaricom would extend their service on Instant messenger and web this would be much more useful. The Website they mention to manage Groups does not seem to be available (or is this just the case from Germany?).

BarCamps are really getting popular in Nairobi. Just last Saturday the 2nd BarCamp at Strathmore University, and today a third version as an informal Meet-up of BarCampers and participants of the Web4Dev conference. This is what JKE forwarded:

The BarCamp will be held at the Pizza Garden in the Jacaranda Hotel in
Westlands on Tuesday evening, 27th November from 5pm onwards. The Pizza
Garden is near Sarit Centre.

I guess I’ll have to move back to Nairobi soon. Mental promised to upload the sessions as podcast and has some BarCamp-photos on flicker. Thanx - and I’m waiting for the podcasts ;-).

(Btw. BarCamp is an ad-hoc gathering born from the desire for people to share and learn in an open environment. It is an intense event with discussions, demos, and interaction from attendees. Everyone should come prepared to stand up and talk about something - this is interactive.)

Linux Terminal Server Project (LTSP) is an add-on package for Linux that allows many people to simultaneously use the same computer. Applications run on the server with a terminal known as a thin client handling input and output. […] Generally, they are low-powered, lack a hard disk and are quieter than desktop computers. […]

This technology is becoming popular in schools as it allows the school to provide pupils access to computers without purchasing or upgrading expensive desktop machines. […] (from Wikipedia)

German TV has a short coverage online (yes, in german). Recently I also posted a presentation-video on a thin client network that has been set up in Malawi.
