In the recent upgrade of my server that also host this website, I noticed a couple of spam email could be useful.

(I'm not asking to be spammed though, so please deter that from your mind Wink )

Mesh GPS network PDF Print E-mail
Blog - Ideas
Saturday, 22 November 2008 00:27

When I was reading the current happening on computer network, I have heard several terms about cloud computing, mesh network, etc.

Cloud computing is basically the possibility where a bunch of computer do the job in a 'similar' manner. As for the mesh network, it is basically the possibility to provide 'wireless' network in a more 'mobile' and robust yet reliable point-to-point network connectivity (or should I say point-through-point?).

So here is another idea related with GPS enhancements:

  • the current car manufacturer starts putting GPS as part of the vehicle navigation system
  • the current GPS manufacturer also gained several market share for customer's demand in having their vehicle equipped with GPS for their navigation need

I also noticed that today, GPS unit available in the market can cater the following user:

  • Pedestrian (very slow mobility)
  • Bicycle or any non-motor vehicle (slow to moderate mobility)
  • Motorbike (open vehicle with moderate to high mobility)
  • Cars, trucks or busses (closed vehicle with moderate to high mobility)

Those GPS user 'class'-es are available for both on-road and off-road (more on this in a separate article).

VMware 2.0 Server Upgrade - too easy! PDF Print E-mail
Blog - Article
Thursday, 04 December 2008 04:42

I finally managed to upgrade my VMWare server to 2.0 build 11xxx (not the latest one).

There were two reasons for the upgrade delay:

  • I keep receiving incomplete/failed download, until 2/3 weeks ago
  • Once downloaded, I keep getting distraction on performing the upgrade

So, here are a couple things that I noticed:

  • The new release, changed its console from application into web-based. The 'VMWare Server Console' changed into 'VMware Server Homepage'
  • During installation, the installer asked for two unused (TCP) ports in the host for management access. One is for http and the other one is for https access. The default is 8222 and 8333 for http and https.
  • The guest console is no longer directly accessible from within the management console. Instead, it is now using browser plugin that pops-up a separate browser window for guest console access.
  • ... and the blue theme is lovely Wink (it's only one bar on top, so don't ask me where is the theme)

The steps that I did for performing the upgrade were quite straight forward:

Predictive (integrated) GPS PDF Print E-mail
Blog - Ideas

Two days ago, I hit with a thought while driving: what is the current GPS is enhanced with some sort of 'predictive' mechanism.

The scenario goes like this:

  • During turn-by-turn navigation, the GPS unit is linked with various sensor and status of the vehicle
  • If the vehicle is making a turn sign (either left or right) and yet it is not yet the 'acceptable' distance, then the GPS unit will start recalculating the alternative route for the (about-to-be) new route.

That's the starting predictive mechanism.
