TechComm Labs : Must be good. Brickbat quotient is quite high

http://tcl.leipper.org/author/bryan

Technologies with a focus on communications and media. Must be good. Brickbat quotient is quite high. It’s like the Upstart and Systemd upgrades to the Linux init system. Boy, did that get some people upset. This time around its Snap, Flatpack, and other efforts to solve application compatibility and security issues. (see 2daygeek). The thing is, software applications often depend upon common libraries of functions. Some of these libraries are provided […]. Ubuntu and its ilk. We live in interesting times.

Technologies with a focus on communications and media. Batteries, ignorance, dreams. Roadtreking waxes eloquent about the amazing lithium battery system in his RV. It is, perhaps, a better lesson on why snake oils sales so well rather than anything useful about RV battery systems. First problem is that he is amazed at the kind of power draw you can get from Li batteries rather than the […]. What glue to use? Kit building and hardware hacking.

TechComm Labs : Winchester house software development

http://tcl.leipper.org/2015/01/winchester-house-software-development

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.

TechComm Labs : The microcontroller human interface

http://tcl.leipper.org/2014/10/the-microcontroller-human-interface

Technologies with a focus on communications and media. The microcontroller human interface. Generally, anytime I see a little box with a 2 line by 16 or 20 character display and a few buttons and whatnot, I think microcontroller. An example is the West Mountain Radio Target Tuner. Engadget says You can now get a 7-inch 3G Android phablet for just $54 in China. You get a 1,024 x 600 LCD screen, 1GB of RAM, 8GB of internal storage, 0.3MP/2MP cameras, a 1,800mAh battery and even HSPA connectivity. This open...

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). 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...

TechComm Labs : Telephony

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.
