There is a purity to the idea of music as the primary goal for the iPod (the phrase “it used to be about the music” always reminds me of Almost Famous and this scene above).  I’ve written about the feature craziness of the iPhone (here), but recently got an iPod Touch for Xmas, so I thought I would try an experiment.  You see, the iPod touch really has only two features – it plays music and video, like any iPod these days, AND it has a WiFi connection, a feature that leads to all sorts of mischief.  I wondered what I could get up to with only the WiFi connection.  Would the device still be useful if it were not about the music at all?

The results were entertaining.  I spent my vacation downloading apps and trying to get as much mileage out of the Touch as I could.  In fact, I’ll give you a preview of the ending: it was a lot of fun.  Let the games begin…

I started my trip to Milan for Xmas with Tripit, a program I’ve used before (but never on the Touch).  I synced my travel plans (with confirmation numbers and quotes), allowing me to tell the rather snotty Italian Avis rental guy that no, it was no ok if the price was 50 Euros more than the quote and yes I do have proof. In Italian this exchange was the rental guy saying  “e normale…” (shrug) and me responding: “NO non e normale.”  (insert look that said “just because I’m foreign doesn’t make me an idiot”).

Once on the road, I could look at my world clocks to make sure that my time zones were in sync.  This isn’t technically a new feature (it’s on the iPod Classic) but I found it very useful.

While in the air, I had read through one of  my kindle books (no not the complete works of Shakespeare – it just makes a nice picture).  It was great to do the same tricks that I do on my kindle:  taking notes, highlighting passages and adding bookmarks.  I also like having access to all my books, with the ability to download the books that I make have deleted or recently purchased using WiFi.  If the screen were 1 inch bigger, this app alone would be a selling point (if you don’t already have a kindle).

At road stops, a quick glance at Google earth provided a bit of entertainment, as I pinpointed my location and explored local attractions.  In the end, I used it for almost the same purpose as Google Maps (also included on the Touch), but I found the controls much more fun…  Turn by turn directions are available from other apps and as there is no GPS on the touch, it’s tough to get more mileage out of mapping features.

Once at my destination, I managed to tune my guitar (picture on the left) and then call ANYONE in my address book for free with Skype (picture on right).

Skype is such a useful app on the Touch that I’d almost buy one if it were a one trick pony.  The ability to call anywhere from any WiFi network saves oodles of dough and somehow, almost magically, the call quality is better than when I call from my laptop.  All you need to make this work is a headset with a microphone built-in – conveniently the same as my old blackberry headset…

Once I had arrived at my destination, there was nothing else to do but enjoy the vacation.  I wrote blog posts using Evernote, my favorite online note taking application.  You can write notes, add pictures, and then sync it all up to the cloud for safe keeping.  I will say that the built-in camera of the iPhone does add to the power of having applications like Evernote, as you can upload shots documents like business cards and such (which Evernote can scan for text and process for you).   However, I enjoyed typing away while in the kitchen with my grandparents.  It was convenient and much more subtle than opening a full laptop.

I won’t go into the details of the rest of my trip, but suffice to say, it was with family so the lively conversation sparked a few ideas which I captured with Remember the Milk (on left), probably the best task application out there (which I wrote about here).  I also had to do some grocery shopping, for which I found the lovely app ShopShop (right).

Also, family conversations inevitably end up in small arguments about relatively insignificant facts.  Wolfram-Alpha to the rescue!  This handy (although expensive) app connects to the full Wolfram-Alpha website (which I wrote about here) and allows you to type natural language queries such as NYC vs Milan (8.364 million people vs 1.298 million people) or my age in days (10061 days).  I find the math functions most impressive in this app (integrals and derivatives computed in seconds), but access to swaths of useless information is an agreeable plus!

For those of you who haven’t had a Panettone, your lives are incomplete.  That said, a quintuple bypass is probably not a life goal so perhaps a fitness app would be useful?  I’ll admit that I haven’t actually worked out per se with this sucker, but it looks great!  iFitness allows you to make up your own works outs from a large collection.  My new year resolutions will involve heavy use of this software – I’ll let you know how it turns out…

To close, I include the apps that are only for amusement.  Flixster allows you to update your NetFlix queue while doing heavy movie research complete with trailers and reviews.  You can also buy tickets and find theatres for new releases.  Also, I’ve included a screenshot of the games I’ve tried so far.  I think Collapse might be my kryptonite (perfectly good evenings gone forever trying to beat the floating bat creature who ruins this Tetris like game with gobs of ink).  Physics free is fun too – it’s not nearly as nerdy as it sounds.

Overall, the grand experiment was a success.  I managed to do many tasks on the one device and could have ignored the music function completely.  I recommend an iPod Touch to any traveler who wants a bit of fun on top of music player.  Let me know if you have any suggestions for me to try in the comments!

I’ve recommended portable applications before (here and here) but in the past year, capabilities have improved even further.  Running full-blown versions of some of the most popular programs from a flash drive has gotten easier.  Moreover, the open-source alternatives to unavailable applications are improving as well.  Here is a breakdown of what I’d recommend.  Download them and install them to your flash drive once, then make copies for friends (to carry around as thoughtful gifts).  My thanks to Lifehacker for giving me this idea last year.

Google Chrome – My favorite browser can now go anywhere.  Keep your favorite bookmarks and settings with you wherever you go.

Firefox Portable – Not everyone is a fan of Google Chrome.  For those on your list who prefer the Mozilla flavored browser, try Firefox instead.  Equally portable  – add-ons can even be installed on the portable drive.

Skype Portable – If your recipient is a road warrior, they’ll already love this application for chat and free calls.  I used it extensively from many countries, calling my wife for free.

Pidgin Portable – For those who use AIM, Google Talk, Jabber or the variety of other chat programs out there, try Pidgin as the be all end all in chat apps.  Pidgin can connect to most services and integrates  your buddy list into one place.

VLC Portable – Videos come in a bazillion flavors these days.  VLC makes simple work out of many formats, avoiding the complications of windows media player codex downloads and such.

Songbird Portable – Songbird is an alternative to Itunes, for those who want to carry a small media library (or a large one).  As Itunes doesn’t come in a portable package yet, Songbird makes a great replacement – even including a music store.

Open Office Portable – If you want to edit a word doc while on the go, Open Office is a great solution.  Capable of opening word, excel, and powerpoint docs, and these days a realistic office replacement, Open Office is a tremendous tool.

SpyDLLRemover – Spyware is not something to trifle with… SpyDLLRemover provide spyware protection and repair, in a tiny package – a great tool for keeping your computer safe.

7-Zip Portable – 7 zip is like winzip on steroids.  This is one of the cases where the alternative is simply better.  Carry this compressed file swiss-army knife with you and never be stumped by a file again…

Keepass Portable – Your mind might be a brilliant machine, but entirely too many passwords make life either very complicated or very insecure (if you’re using just one password for everything).  Keepass portable provides a safe repository for each of your passwords, without compromising security.

WinDirStat Portable – Is your hard drive mysteriously full?  Can’t seem to find that 20GB file that is hogging all your space?  WinDirStat scans your computer and maps out the contents of your drives.  The visual results make quick work of cleaning house.

Notepad++ Portable – A text editor to destroy all others.  Writing code?  Simply need a way to edit text files on the go?  Notepad++ will get you there.  Improved find/replace, among many other features, will make you forsake notepad for ever.

Finally, you’re going to need some flash drives – I don’t normally try to generate revenue from Just an Asterisk, but in an effort to recoup my costs for running the site, I ask you to buy your USB drives from the following Amazon link.  When you do, they throw a few bucks my way.

If you’re simply not interested in buying flash drives, you can always make a small donation (of any amount) via PayPal secure checkout using the link below.

Thanks for reading and the happiest of holidays to you all!

I have a webcam which I never thought was bad but whenever I video-chat with anyone they always say it’s grainy and the picture is not very good.  So, I was planning on getting a new one and was wondering what to look for.  Is expensive always better?

Great questions!  There are two major concerns with a webcam (other than price) – Frames and Resolution.  However, before you think about buying something new, consider the following options.

Connection Speed and other animals

Although I’d love to tell you that getting a new webcam would do the trick, there are other issues that you should understand.  I found a great resource here with some very technical details.  However, before you dive into that, I would suggest trying the following:

1. Make sure your camera plugs into your computer directly (and not through a hub).  You don’t want any other devices to share your potential speed.
2. Remember that Skype video quality will be better after a few minutes of a call, so don’t expect the best quality when you first connect.
3. Do a speed test of your connection at Speed.io.  A slow connection will make all of your webcam purchasing totally pointless…

If all that turned out fine, then on to the techie gooey details…

Frames

I guess it’s not much of a secret.  The more frames you have, the more times you get to see the image, therefore the smoother the result.  The human eye does not process images like a video camera, so we don’t have a “frame rate” for our eyes.  However, just to give you a point of reference, at the movies, we enjoy 25 frames per second (fps), while on TV it is more often around 30 fps.

In the interest of completeness, I should add that the human eye makes all of this a bit complicated by adding a twist: a blurred image at a slower frame rate can look the same as a sharp image at a higher frame rate.  This isn’t terribly important, unless you are planning to webcast from a moving car, but it’s worth knowing that the subject isn’t quite as simple as it sounds.

My theory, when it comes to webcams, is that you want to stream video, so you’re looking for 30fps.  The good news?  Nearly all camera’s these days, over 10 dollars, have an acceptable frame rate.  All you have to do is know that frame rate exists and watch out for frame rates (if listed) under 30fps.

Resolution

Resolution is the number of pixels per inch.  What is a pixel?

A decent zoom	A crazy zoom

Do you see the little tiny red dot in my crazy zoom?  That is a pixel.  In a way, it’s just a piece of color information.  Make it red (like in my example) and it causes a tiny defect in the image.  The more pixels you have per inch of space, the more information is there for a computer to display.

72 pixels per inch	5 pixels per inch

So what kind of resolution should you buy?

Here are the options (as of the date of this post) on CNET.com.  352×288 stinks.  1280×960 rocks.

The thing to remember is that the resolution is simply how good the image taken could be.  Therefore a really, really cheap webcam that can pump out 1280×960 may not be the best choice.

Also, watch out for “effective resolution”.  Sometimes a low resolution camera will tout itself as a better product by saying that with software, which they include, you can increase the resolution from the standard provided by the lens.  My personal advice would be – try to find a decently priced camera, with good resolution out of the box.

Most internet connections cannot support the highest resolutions of today’s webcams.  However, getting a better top end may improve performance around 800×600 (where most people end up streaming).

Conclusion

I hope this helps.  To summarize, you need to look for a frame rate near 30fps, although you might only stream at 800×600 – consider a higher resolution and finally, remember to check your connection speed.  If you follow those basic guidelines, you’ll be fine with a mid-range webcam (at this moment between 30 and 60 USD).

Good luck!
