Technologies with a focus on communications and media. Winchester house software development. Jon Evans’ Three Reasons Why Your Software Is So Far Behind Schedule. Got me thinking about Winchester House ( wikipedia. Software development. His rationale is that it is “technical debt” rather than an irrational effort to keep ghosts at bay – but maybe technical debt is indeed just such an effort? Saturday, January 31, 2015, at 10:06 am.

Technologies with a focus on communications and media. PCD (personal communications device a.k.a. smartphone) theft and trivia. Some interesting trivia by Robert Brokamp when describing How to prevent mobile phone theft. According to Consumer Reports, 3.1 million smartphones were stolen in 2013, which was nearly a 100 percent increase from 2012 s number. Another 1.4 million were lost.

Void - Debian Wheezy Image for Seagate Dockstar
http://wej.k.vu/dockstar/debian_wheezy_image_for_seagate_dockstar
Debian Wheezy Image for Seagate Dockstar. I've been running Arch Linux on most of my machines, including the Dockstar, but I am getting more and more annoyed by the horrible system breakages that occur regularly when updating Arch. The amount of maintenance required is just too high for my taste - even for a rolling release distro it does not have to be that bad. To get a working Debian installation for your Dockstar, you have to use debootstrap, or Doozan's Debian install script. Thank you for the image!

Gatta’ have those TLA’s (three letter acronyms) so I’m calling the modern smart phone a PCD (personal communications device). Ye olde flip phone’s external LCD decided that it was going to emulate a modern art postage stamp rather than communicate things such as time or date or ID of incoming calls. That screen was a […].

Technologies with a focus on communications and media. Paradigm shift: cell phone to PCD (Personal Communications Device). Gatta’ have those TLA’s (three letter acronyms) so I’m calling the modern smart phone a PCD (personal communications device). Utility and variety issues were similar then to the situation now. The second key is in the hardware. The modern PCD has sensors to detect its position, movement, and environment. Radios are available for the cell phone network, WiFi, Bluetooth, and GP...There...

Technologies with a focus on communications and media. The Amp Hours confusion. When it comes to batteries, the energy capacity is often given as Amp-Hours. For smaller batteries like those used in portable devices, this often shows up as milliamp-hours. This can be misleading because a proper measure of energy needs volts as well as amps over time. An example is the auxiliary batteries available for charging […]. Disruptive Technologies: Cell phones. We live in interesting times. Primer on digital voice.
