DropBox LAN Sync

I've enjoyed DropBox as a very good synchronisation between multiple machines. With web and mobile clients as well, one can access your data from anywhere, anytime.

Today I've found another briliant feature, DropBox LAN Sync.

Let me explain. I decided today that my notebook needed a format, so I popped the recovery CD's in and after a couple off minutes, she was up and running. Now because of the format, this machine would have to re-sync the whole DropBox file collection. Now I do have a 4Mbps Uncapped MWEB ADSL service, but still, at a maximum of 400Kbps it would take around 10 hours to sync the 8Gb of files.

Seeing that I use DropBox on my Android Mobile, Mecer Lucid Windows 7 10.1" Slate, Acer Aspire One Netbook, Toshiba Z11 Notebook and Ubunutu 10.10 Server I already have all the files I need on my local home network.

DropBox has a simple feature which allows it to find your other linked machines on the local network, and then rather sync between the local machines, and not back over the Internet.

So incase you still have not tried it, download it from and give it a try. It's free!!!

WhatsApp (mobile post)

The ultimate mobile instant messenger, and no other way to put it!

I had two friends (thanks Wally and Louis) say I should try it, but they couldn't give me a good enough reason but that it works on BB. Well, here are some good reasons from Android's view.

Contact list is build from the numbers in you address book, or people in the case of Android. On registration it send a SMS from your mobile to confirm your registration. It then runs the numbers in your addressbook against other registrations and builds the contact list. No adding people in another IM application, just refresh the list and off you go! Contact links also works on the Android.

Group chat is awesome. Now build groups to chat to easily and quick. Organize a braai quickly with the chicks and guys in one conversation.

Attach things to the chat, quick and easy. Photo, video or sound from camera or library. Current location from GPS or contact card from contacts.

Delivery and read confirmation. Something that is apparently on BBM, but just works wonders when in use. Now see that someone did get the message and is ignoring you!

Conversations to platforms that do not have it. If you've never had conversation based mail or SMS, you are missing out big time. This application shows what live should be like conversation based.

Overall, I'm impressed and can strongly recommend this application to everyone.

Have fun chatting on a new level and stop SMS'ing me!

Pretoria WUG Wierdamall Highsite (mobile post)

Today I spent a good part of the morning at the Pretoria WUG Wierdamall Highsite. This highsite is located on the roof of the office block for Wierdamall.
This site is assembled on a 9m tower and comprises of 2x RB433 boards servicing users onto 4 sectors, 1x RB493 to handle routing and QoS and 4x Rocket dishes for backbone links into and out of the site.
The main thing we changed was the layout of the sectors. Up to now, expantion was done horizontily causing partial overlapping. We now changed it vertically. We placed two sector antennas on top of each other, covering the same area on another frequency. Horizontal overlapping is kept to a minimum.
Feedback from users are already very positive an we will see what happens under load.
This is why I joined the WUG, to learn. Here one can make drastic changes and monitor the result, learning from the outcome. Feedback from users might be lacking, but reading between the lines helps.
