Change the default width of Blogger posts

The visualizations from Google Fusion Tables are wider than the default width of Blogger. To prevent Blogger from cutting them off on the right, change the default width of Blogger posts.

  1. Go into the "Layout" tab
  2. Click "Edit HTML" 
  3. Download a copy of your current template just for back-up. 
  4. Find the editable text box. 
  5. Scroll through the content until you see "Outer Wrapper"
  6. Under "#outer-wrapper" change "width: 660px" to "width: 1000px"
  7. Under "#main-wrapper" change "width: 410px" to "width: 750px"
  8. Tip: if the numbers aren't precisely 660px and 410px to start with, don't worry.
  9. Click "Save Template" and view your blog post again.

GPS implants: small RFID implant and a nearby GPS receiver.

NaviGadget -- GPS Navigation Systems, GPS Tracking Devices, GPS Phones, Receivers, Reviews, and Hacks:

An article is kind of stating the obvious – at least for us – saying that GPS implants, the size of a grain of rice is not technologically feasible considering our current state with batteries mostly.

This Mexican security company claim they made 178 rescues using a small RFID implant that goes under your skin and it relays a signal to a nearby GPS receiver. If the GPS and the RFID implant get separated the company claims they can pinpoint person of interest.

This sounds a lot like science fiction however since RFIDs do not have a power source of their own and can not transmit signals. An RFID reader can only pick up their existence from at most a couple of hundred meters provided the person is still near the last location of the GPS tracking device.

ActMAP (Actualize Map); the complexity of multiple map suppliers and multiple versions of in-vehicles maps, Map database management -GPS

Map database management:
A European consortium called ActMAP (Actualize Map) is "developing standardised mechanisms to update existing map database content and enable dynamic attachment of information to the digital in-vehicle map".

The ActMAP consortium comprises ERTICO (coordinator), BMW, CRF Fiat Research Centre, DaimlerChrysler, Navigon, NAVTEQ, Tele Atlas, and Siemens VDO Automotive.
They have finished most of their work and published a number of reports, which were submitted to the ISO committee TC204 WG3 for standardization. Their reports serve as a good starting point and reference for the work of this project.

An important issue their reports address is dealing with the complexity of multiple map suppliers, using proprietary formats, coupled with multiple data suppliers and multiple versions of in-vehicles maps. They resolve this by using an open intermediate map format expressed with XML and based on the concepts of the ISO standard GDF 4.0. All modifications to a supplier's database are first converted to this intermediate format, stored on a server and then converted to each format used within individual vehicles.
