User Interface Testing/QA Tool for Web Developers

A good friend of mine, Vid Luther from PHPCult /, Selenium IDE screenshotshowed me Selenium, a nifty Firefox extension, today for developing test cases that you can play back into the Firefox browser including pauses, delays, keystrokes, form values, and link clicks.

Selenium IDE is an integrated development environment for Selenium tests. It is implemented as a Firefox extension, and allows you to record, edit, and debug tests. Selenium IDE includes the entire Selenium Core, allowing you to easily and quickly record and play back tests in the actual environment that they will run.

If you find yourself repeatedly running the same user flow tests on a website or web application, try out this extension today!


Data Visualization – Oh So Pretty!

Have you ever been into a meeting with a presentation being shown by some techie or project lead that attempts to describe some kind of trend or probabilistic projection and been bored by the visualization? Well many sectors of the economy rely on very simple visualization tools that aren’t at the fore front of data visualization and mining techniques that are available nowadays.

In the recent past I’ve posted about Google Maps mashups with heat map technology but there are many powerful tools out there (some web based, others not) that intrinsically yield powerful trends that may not even have been discoverable with simple charts, graphs and basic visualization tools of the past era.

An article in has catalogued and captured screenshots of the most amazing and beautiful data visualization models out there including everything from 3d heatmapping/contouring, content clouding, to mind mapping.

One of my favorites is a 3d visual population hill/spike density map from Time Magazine:
Time Magazine uses visual hills (spikes) to emphasize the density of American population in its map.

If you are in the business of analysis of any kind, you should definitely read this article and check out the screen shots. You might find the technologies that these companies are creating useful to your endeavor.


How to Avoid the 10 Biggest Mistakes Freelancers Make

Having been a freeleancer myself in several realms (branding / design, IT / software architecture and engineering, business development and strategy planning, operations) I’ve learned a lot from my own experience dealing with clients of all types. I recently came upon a great Digg post that might help fellow free lancers out there to avoid certain mistakes that could hurt your livelihood and career. A lot of these tips I’ve learned through my own sweat but the writer of the original post puts it altogether so well.

These mistakes can easily be made by design firms and other outsourcing companies as well so this doesn’t just apply to potential freelancers.

Essential TabletPC tools and software

So I’ve been yapping about touch screen technologies a lot this year (Apple iPhone, Microsoft Surface, Jeff Han’s Multi-touch) and you may have enjoyed the essential tools I’ve posted for Apple’s iPhone but I thought that my fellow TabletPC friends out there could enjoy some of the tools and resources that I’ve been enjoying on my TabletPC.

Also if you’re not yet a TabletPC lover and are thinking about getting a laptop PC in the near future, I recommend you review and compare the prices / features of your choice notebooks and also the top TabletPC’s out there. I own the Lenovo Thinkpad X61 TabletPC which I believe to be the best TabletPC out there by far in comparison to the others.

Now here are your tools. Enjoy!

A New Theoretical Model for time travel being imagined

Technion Israel Institute of Technology researchers have developed a theoretical model of a time machine that, in the distant future, could possibly enable future generations to travel into the past. An article on this research was published last week in the scientific journal Physical Review.

By tweaking Einstein’s space time and general relativity models these researchers are becoming more confident with the idea of travelling back in time, something that most scientists believe to be improbable because of the paradoxes and other reasons that could happen if one did so. Curving space time, as is the basis for wormholes to travel instantaneously from one point in space to another, is the basis for this research. So instead of going to another space point in your time, you go from your point in time to another point in time.
