MobiOne Promo Code - app development software One of the highlights of my year thus far has been publishing iOS apps with kids. We've gotten two apps successfully published in the App Store and are working on several more. As of this writing, we have one in review that we hope will be approved soon. I often get asked how we publish apps, since this is not something that is typical...

Two quick links on Cognitive Load Theory I've been fielding lots of questions lately about Cognitive Load Theory. Here are two quick links that may be useful. First is an article talking about the practical implications of CLT on the design of learning. The second are some "recent" (as of 2003) developments regarding CLT. Happy reading! Update: I clarified the second...

Practical advice on kids and Android app development After hearing about my students' success developing an Android app, I've gotten several emails asking for more details as to how I practically worked with my kids. Here are some pointers that I offered to the first person that emailed me, perhaps they are of some use to you. Please note that your mileage may vary. It's ok to not be...

Publishing an App Inventor app to the Android Market As I mentioned earlier, my students and I published an Android app to the Android Market. See those links for more information on the background. This post is decidedly technical. First, once we finished the coding process, we packaged the app for to download to the computer. This is an option in App Inventor. This downloaded an .apk file....

Graduate School, here I come!

Category : General

I didn’t do so well in my first few years of undergraduate studies. I went from a very populated section of southern Florida (Broward County) to Presbyterian College, in Clinton, South Carolina (population 10,000ish back then) a sleepy former mill town. Can you imagine the culture shock? Couple my shock of moving to a state where the confederate flag still flew above the state house with the overnight change of being a high school senior to a college freshman, and I was doomed. I made poor choices and had terrible study skills, and it ended poorly. I transferred to the University of South Carolina (the REAL USC ;) )in the Fall of 1997 and spent a couple of years trying to figure out what I was going to do. I dropped out, and didn’t go back until 2002. I finally graduated with my BA in 2004. Well here we are a short time later and I am going back for a Master’s.

I’m a glutton for punishment.

At nearly 30 years old, I am certainly more mature than the first time I started college, and I am even a little excited. I am more organized and less interested in fraternity parties.

Here are the two courses I am taking to start off…

EDET652 – Design & Application of Academic Games

EDET709 – Application of Learning Principles to Educational Design

We’ll see! I’ll let you know how it goes. It begins Tuesday…

How to run Windows under Ubuntu

Category : General

So I installed a fresh copy of Ubuntu 6.10 Edgy Eft on my Sony Vaio 2.4 Ghz 40 GB 4200 RPM (yuk) HD that has a couple of years on it. I was running Edubuntu and it was running a little bloated, and some of the educational software got a little excessive. So here I am with a fresh install of Ubuntu and loving it. So needless to say, I had to try out Brian’s comment, right? Here is what he said…

Hi I would suggest instead of dual booting to try running XP under VMware Server (its free).
Installing it under ubuntu is easy:
0: sudo apt-get install linux-headers-`uname -r` build-essential xinetd
1: download and extract VMware Server
2: sudo ./vmware-install.pl
3: Accept all defaults

http://ubuntuforums.org/showthread.php?t=183209

Can’t be that easy, right? Well, it was enough to catch Miguel‘s attention, so I perked up and listened. He’s a few (lots!) ahead of me with open source, so if he digs it, and calls it fantastic, I should too, or at least I should try it.

So I did.

It’s awesome! It works like a charm! The only suggestion I might add is to get a serial number ahead of time. I had to re-run the config script because I didn’t have a serial number handy. No big deal though, just a few extra minutes and a lesson learned.

So go, try this! It’s amazing!

I am going to go play with it some more, but it looks like a solid solution. Now to try and figure out how to install XGL. Or maybe I should just stick with that cool firefox extension that gives you XGL-life effects when you switch tabs. Man I wish I could remember the name…oops.
Do you know the extension to which I refer? It’s installed at work, so I can fix this tomorrow. Or can you help me now?

KompoZer – a release of Nvu without the bugs

Category : Software

I had been a little frustrated with Nvu of late. Now I don’t do a whole heck of a lot of web design these days. If I am looking at code, it is probably within the context of a content management system. I may hack a sidebar here, or call a function there, but long gone are my days of staring at a blank notepad screen typing out html code. I am glad I have that experience, as it helps me put together quick and dirty pages when all I need to do is embed a quick tutorial video. Heck, Google video did the encoding code for me, so all I did is wrap it in html, title, and body tags, center it up and I was golden.

When I was working on my new entry portal to be used when folks want to find me (yikes!) I naturally turned away from those evil proprietary softwares (which I really just don’t own ;) and looked for an open source solution. Along came, Nvu, a solid WYSIWYG based editor. Except it is a little frustrating due to a couple minor bugs.

Enter KompoZer. They bill themselves as “Nvu’s unofficial bug-fix release”. KompoZer is available for all three platforms. Enjoy (mostly) bug-free web editing!

WordPress 2.0.6 is available

Category : Software

Caught this in my dashboard, and inside of fifteen minutes I upgraded three blogs.

WordPress 2.0.6 has been released, roughly a day ago and sports a few bug fixes and security releases.

Their upgrade directions indicate a process involving deleting directories, backup up and the like. Me, I’m a bit wreckless.

All I did is extract the file on my machine and FileZilla’d it straight up, knowing that it would not overwrite my config.php file (since WP doesn’t ship with one preconfigured). Nor were my plugins in danger, save for the fact that they would be infected by close contact with the Hello Dolly plugin that ships with WP. All I can hope is that it was the Carol Channing (I met her) version of Hello Dolly.

Anyhoo, it works flawlessly as far as I can tell. The sites look the same and it threw no errors. It copied in record time and doesn’t seem to show any ill effect (nor any positive effect, but hey).

So go upgrade! Security risks are abound for the late adopter!

Have I become anti-Windows(r)?

Category : General

I can’t tell for sure, but I think I may have become a little bit anti-Windows(r).

This time last year I had two computers, a desktop which is an AMD Athlon 3000+ running Windows XP Professional and a Sony Vaio 2.4 Ghz P4 which ran Windows XP Home painfully slow. I attribute the slowness to the fact that the whopping 40GB hard drive spun at a resounding 4200 rpm. Not fast enough to keep up. I upgraded it to 2gb of RAM which helped very little.

Now, I find myself surrounded by a pleasent ambiance of Mac. Let me explain my desktop setup. It has recently been the topic of conversation by some family visitors to the house.

Farthest to my left (within reach) is a 15″ 2.16 Ghz MacBook Pro (Intel) which handles alot of my iTunes needs when I am not traveling. Sometimes I will let it run Skype if I am participating in a Skypecast or interview so I can multitask on this machine.

Next to that is a Dell 19″ LCD Monitor which displays (using the DVI) a larger version of the MacBook pro desktop. When switched to analog mode it displays the ever heart-wrenching Windows XP display from the Athlon machine mentioned above. Truth is, I hardly ever turn that one on, partly because the on-board video chipset fan is going bad and it whines until I stop and start the fan a few times. Also one if its three hard drives died recently, an older 20GB. I built this machine, and am sad to see it falling apart. That fan is almost impossible to find since it’s for the on-board video I don’t use.

Next to this monitor is my 20″ Intel iMac. This is the machine I use primarily, and the one I am using to write this. If you had told me a year ago that I would be a Mac enthusiast, I’d have called you silly. Now, I am eating my hypothetical words. It has taken some adjusting, but I am in a position now that I absolutely love my Mac. There are a few programs I wish existed for the mac (Picasa and Filezilla, namely) although I have found alternatives (picasa exporter for iphoto and cyberduck), but other than that the sheer uptime and reliability is worth millions to me. I rarely restart it, just put it to sleep. I have found myself increasingly impatient when I turn my Windows machine on since bootup takes forever.

To the right of that machine is that older Sony Vaio laptop I mentioned earlier.

It’s running Edubuntu.

And runs it very well. I don’t have wireless for it at the moment (wife’s laptop uses the NetGear card) but it serves well as a backup.

I am considering a new primary hard drive for the “big” machine (the Athlon 3000+) and a fresh install of Ubuntu. I would have to make sure I could still boot into Windows occasionally without having to connect and disconnect cables, but it is an option still.

Ok, all that said, recently two different people have asked my opinion about new computer purchases. Assuming I await the new Best Buy ad with bated breath, they wanted to know what machine from a big box store would be the best for their purposes.

Being the geek that I am, I managed to covince the first couple to seriously consider a mac (education discount, anyone?), and I am going to install Ubuntu linux on the other couple’s machine, potentially saving them the cost of a new PC and breathing new life into that old machine.

Does this make me anti-Windows (r)? With Vista coming out, I have no computer capable of running it, and no desire to do so. I like the near-zero threat of viruses and spyware/malware. I like reliability and uptime. I like that my machines (save for the Windows one, but naturally that is hardware, not software) “just work”.

So why am I steering folks away from Microsoft? It is not for any philosophical reason, I don’t claim to know much about either company’s business practices, I guess I am just a bit of a pragmatist in the narrow definition that I just like to help folks find stuff that works.

It saves me the phone calls during dinner when they can’t figure out why they’re all of a sudden getting thousands of pop-ups.

Anything I can do to avoid being someone’s personal (and assumed free) tech support is worth a lot. It gives me more time to talk to you, and I enjoy that.

Update: I accidentally mentioned that folks think I await the Best Buy ad with baited breath, when in fact I should have said bated. Thankfully, the grammarcops only gave me a warning this time. Thanks, grammarcop!
