Where are touch screens going ?

I, like many others, enjoy a smart phone with a big touch screen. Many people don't like the big touchscreen for one major reason: tactile response. It is for that reason that a lot of people opt for Bleckberry phones and symbian os phones that have a small physical keyboard. I never minded the keyboard much on my old treo (before I moved to an iphone), but I got used to the iphone screen pretty fast too.

I have to admit that there is a challenge when trying to operate a touchscreen based keyboard, especially with one hand. (I won't tell "where i am" or "what I am doing" at the time that this is the biggest issue, and I won't ask you either...).

The iphone and newest android phones try to compensate for this issue by doing "click" sounds or screen buzzing tactile response. It kind of works, but you still can't tell whether you hit the "j" versus the "k" on the virtual keyboard, especially when you have big sausage fingers.

Enter a new technology called "Tesla Touch" by Disney Research. According to the sources, this new technology uses electronic pulses and/or vibration to change the sensation under the user's finger. This can apparently be used to make the screen feel rough or rubbery, or even make certain "hot spots" feel heavier or lighter for "drag and drop" operations. Supposedly this could be used to make a virtual keyboard that users can "feel" and accurately type on.

Sounds exciting, but will I still know the difference when I type a "j" versus a "k" ?

Installing python 3.4.x on OSX El Capitan

I love "brew" package manager, but sometimes being too progressive breaks things.  I have several python apps that I maintain that get deployed to AWS using Elastic Beanstalk.  AWS eb can deploy with python 2.7 or 3.4.  Any recent 'brew install python3" will get 3.5.1. #annoying

Making Macbook Air with 128GB SSD usable with Bootcamp

I recently got a new Macbook Air 11" (the 2012 version) and loaded it with goodies like 8GB ram and 2GHz Core i7.  What I DIDN'T upgrade was the internal SSD.  My config came with 128GB SSD and I refused to pay $300+ to upgrade it to 256GB.  Yeah I know, some call me cheap, but SSds cost $75-$150 for 240GB, so adding another 128GB for $300 seemed way too steep for me.  I figured "ok, I'm going to make 128G work!"

Here is the story of how that went...

Getting Started with OpenVAS on CentOS - an open source vulnerability scanner

The Open Vulnerability Assessment System (OpenVAS) is a framework of several services and tools offering a comprehensive and powerful vulnerability scanning and vulnerability management solution. (Taken from the OpenVAS website, which is at )

This blog entry will introduce OpenVAS version 3.1, walk through installation on CentOS and is intended as a "getting started" guide. I'll also do a guide for installing on Ubuntu later.
