Here are two Android Apps I created that are now available on the Google Market Place (Google Play). They are both free and both display surf reports for the states of NJ and NC. I created these apps in Eclipse using Java. They are the first apps I have created using Java. I actually believe it might have been just as much work as using the Google App Inventor. I will now be creating all of my apps via Java from now on and doing some more advanced stuff in the future as I have time.

File sizes and download speeds of 56k, 3G, 4G, and High speed wireless internet
Here is a chart I made comparing speeds of various internet connections and showing how fast/slow one would expect their files to download. Remember that these are really hypothetical and depend so much on where you are, what kind of device you have, etc. You should also remember that equipment you are using should be regularly maintained (visit BoostPoorSignal.com for more info). Theoretically 4G and high speed internet should be nearly the same but realistically this is not the case. So please do not take these as fact, rather, use this chart as a guide to consider when developing for both web and mobile devices.
| 100kb | 250kb | 500kb | 1mb | 1gb | |
| 56k Modem | 15 seconds | 36 seconds | 1 minute | 2.5 minutes | 1 day 18 hours |
| 3G | <1 second | 6 seconds | 12 seconds | 25 seconds | 7 hours |
| High Speed/Wireless/4G | <1 second | 1 second | 3 seconds | 5 seconds | 1.5 hours |
*note – these speeds assume best case scenario. More than likely all speeds will be
Slower. Both 3G and 4G speeds will probably be significantly slower, especially as 4G max.
Your PC behaving strangely? Is it very slow? Does it crash very often? Doesn’t it boot at all? Well, these are common problems, that everybody have met in their life – to be honest, I’ve got these problems several times – and this comes from several reasons, but the first is: tech devices ages very fast. Xtra-PC is a small USB device that you plug into an old, slow or dead computer (Windows or Mac) to give it new life. Basically, it’s a custom operating system, based on the proven foundation of Linux, that runs directly from the Xtra-PC USB device, and it even works on computers with a missing or crashed hard drive.

Speeds are not even available yet.

Microsoft giving away xbox 360 when you buy a windows machine for school
This is a pretty cool offer for students. Buy a laptop, get an xbox 360. Here are the details:
“Students. PCs. Free Xbox 360. The Redmond team’s at it yet again. Similar to last year’s deal, Microsoft’s hooking students up with a 4GB Xbox 360 if they drop some cash on one of its Windows machines. It’s simple: shell out over $699 on a PC, or $599 if you’re in Canada, and you’ll be walking out with a shiny new console free of charge — naturally, you’ll have to do so at participating shops such as Best Buy, Fry’s, Newegg, Staples, The Source and, of course, Microsoft’s own stores. The promo is set to kick off here in the States on May 20th, while those living in the True North can take advantage of it starting today. And before you ask — yes, you will need to show your scholar credentials to get in on the bargain.”

Facebook IPO
Will you be buying? I will not be – not because I do not have the money (Although I do not because I am a college professor which means I cannot even afford to live). The reason I would not buy at least in the long term, for those looking for investments, is that this company can go down and fail overnight. If you do not believe me, look at myspace or any of the IPOs in the early 2000s during the tech boom. On the other hand as a short term investment for the person who watches the market and pay attention to what is happening in the tech world, this is probably a decent investment as it will go up right away just as google did. The key here is watching and knowing when to get rid of it. The best part of everything was watching and learning how big financial firms operate in the market and do things. SoFi is such a big player and any advice they have for you is something id recommend.

What is Human Computer Interaction – HCI
What is HCI?
“Human-Computer Interaction (HCI) is the study and the practice of usability. It is about understanding and creating software and other technology that people will want to use, and will find effective when used. The concept of usability, and the methods and tools to encourage it, achieve it, and measure it are now touchstones in the culture of computing” – Carroll (2002)
HCI is how we interact with computer hardware and software. Not just computer though, but all machines – such as your car, dishwasher, airplane etc. The point of HCI is to make these technologies more ‘user friendly’ so that they are easier for us to interact with both physically and mentally. The key to HCI being usability – so expect more blog posts on usability.
Presentation on mobile learning
Doing a presentation tomorrow on Instructional Technology projects for UNCW. The presentation is highlighting what we are doing in our program. Here is the presentation.
UNCW Board of Visitors Instructional Technology presentation: uncw_InstruTech2012
Classes begin today!
Summer courses begin today. I will be teaching a graduate course: Computer Interface Design. The course will cover HCI and interface design strategies then move into Adobe Photoshop. Students will develop several interfaces and projects using Photoshop. I am very excited, this is going to be a fun course.
Do you trust ‘information’ and ‘history’?
This is a very interesting tale of a professor whose class was designed to try and create a fake part of history via the web. They made up a person and a story about them. This is very fascinating and makes me wonder how much of history was made up? Are there things we believe that were simply the act of someone trying to trick us?
From the article:
“A woman opens an old steamer trunk and discovers tantalizing clues that a long-dead relative may actually have been a serial killer, stalking the streets of New York in the closing years of the nineteenth century. A beer enthusiast is presented by his neighbor with the original recipe for Brown’s Ale, salvaged decades before from the wreckage of the old brewery–the very building where the Star-Spangled Banner was sewn in 1813. A student buys a sandwich called the Last American Pirate and unearths the long-forgotten tale of Edward Owens, who terrorized the Chesapeake Bay in the 1870s.
These stories have two things in common. They are all tailor-made for viral success on the internet. And they are all lies.
Each tale was carefully fabricated by undergraduates at George Mason University who were enrolled in T. Mills Kelly’s course Lying About the Past.
Their escapades not only went unpunished, they were actually encouraged by their professor. Four years ago, students created a Wikipedia page detailing the exploits of Edward Owens, successfully fooling Wikipedia’s community of editors. This year, though, one group of students made the mistake of launching their hoax on Reddit. What they learned in the process provides a valuable lesson for anyone who turns to the Internet for information.”
