More of my thoughts have been stolen: In my
previous job the customer wanted a progress bar displayed while information was copied off of proprietary hardware, during which the software didn't get any indication of progress until the copy
was finished. I joked (mostly) that we could display a progress bar that continuously slows down and never quite reaches the end until we know we're done getting info from the hardware. The amount
of progress would be a function of time where as time approaches infinity, progress approaches a value of at most 100 percent.
This is similar to Zeno's Paradox which says you can't cross a room because to do so first you must cross half the room, then you must cross half the remaining distance, then half the remaining again, and so on which means you must take an infinite number of steps. There's also an old joke inspired by Zeno's Paradox. The joke is the prototypical engineering vs sciences joke and is moderately humorous, but I think the fact that Wolfram has an interactive applet demonstrating the joke is funnier than the joke itself.
I recently found Lou Franco's blog post "Using Zeno's Paradox For Progress Bars" which covers the same concept as Zeno's Progress Bar but with real code. Apparently Lou wasn't making a joke and actually used this progress bar in an application. A progress bar that doesn't accurately represent progress seems dishonest. In cases like the Vista Defrag where the software can't make a reasonable guess about how long a process will take the software shouldn't display a progress bar.
Similarly a paper by Chris Harrison "Rethinking the Progress Bar" suggests that if a progress bar speeds up towards the end the user will perceive the operation as taking less time. The paper is interesting, but as in the previous case, I'd rather have progress accurately represented even if it means the user doesn't perceive the operation as being as fast.
Update: I should be clearer about Lou's post. He was actually making a practical and implementable suggestion as to how to handle the case of displaying progress when you have some idea of how long it will take but no indications of progress, whereas my suggestion is impractical and more of a joke concerning displaying progress with no indication of progress nor a general idea of how long it will take.
I signed up for the pre-release beta and purchased a Chumby last year. Chumby looks like a cousin to a GPS
unit. Its similar in size with a touch screen, but has WiFi, accelerometers, and is pillow like on the sides that aren't a screen. In practice its like an Internet alarm clock that shows you photos
and videos off the Web. Its hackable in that Chumby Industries tells you about the various ways to run your own stuff on the Chumby, modifying the boot sequence (it runs Linux), turning on sshd,
etc, etc. The Chumby forum too has lots of info from folks who have found interesting hacks for the device.
When you turn on the Chumby it downloads and runs the latest version of the Chumby software which lets you set alarms, play music, and display Flash widgets. The Chumby website lets anyone upload their own Flash widgets to share with the community. I tried my hand at creating one using Adobe's free Flash creation SDK but I don't know Flash and didn't have the patience to learn.
Currently my Chumby is set to wake me up at 8am on weekdays with music from ShoutCast and then displays traffic and weather. At 10am everyday it switches to showing me a slide-show of LolCats. At 11pm it switches to night mode where it displays the time in dark grey text on a black background at a reduced light level so as not to disturb me while I sleep.
I like the Chumby but I have two complaints. The first is that it forces me to learn flash in order to create anything cool rather than having a built-in Web browser or depending on a more Web friendly technology. The second complaint is about its name. At first I thought the name was stupid in a kind of silly way, but now that I'm used to the name it sounds vaguely dirty.
I saw this odd looking cute cat and it reminded me of Thom Yorke. On a related note also see the myth buster lol-cat.
Also I think the whistling puppy (~0:05) and hungry lumas transforming on Super Mario Galaxy (~0:15) sound very similar.
My manager has come back this week from a 10 week vacation and paternity leave. In response and similar to other office hacks some dedicated coworkers and I decided to do something to my manager's office.
While gone we knew my manager, Venkat, was getting into meditation. My coworker Vishu had the excellent idea of easing Venkat back into work by making his office
better suited for meditation. To start with, we updated his nameplate with an Om.
Next we emptied his office of anything that could distract him from meditation and replaced it with a yoga mat. Of course I left a copy of the specification
for the remodel in his office.
After Carissa and Elijah's wedding Sarah and I went to San Francisco. We drove in, well Sarah drove anyway, still in
the PT Cruiser Sunday morning and checked into our hotel, Hotel Diva. I was originally concerned that I wouldn't fit in as I don't really consider myself a
diva, however the hotel was cool. They have Internet rooms setup in various themes, the front desk is always staffed, our room had a very modern look, and when we entered the flat-screen over the
front desk was playing an episode of Aqua Teen Hunger Force.
We walked around a bit before going to the SF Museum of Modern Art. There was a Picasso exhibit at the time
which we could see for only $3 more. It felt kind of wrong like my ticket was super-sized. I think the most memorable piece I saw was three white
panels which consisted of three blank panels. Art. Sure. After that Sarah wanted to see the giant Hello Kitty store she had heard of from her sister. We ended up going to the Westfield Shopping
center which has a disappointingly average sized Hello Kitty store. Apparently the giant one is gone. That night we went to First Crush for dinner. I had a
flight of wine which consists of three one-third sized glasses of various but complimentary wines. It was a great restaurant in terms of food, drink, atmosphere and service.
The next morning we were even more the tourists when we went down to Fisherman's Wharf and Pier 39. We visited the famous wax museum and purchased multiple
pounds of taffy. On the way back to the Oakland airport we got to experience a little traffic as part of the
580 freeway had collapsed the morning we arrived and was still under repair on our way out. We survived of course and I think the trip went rather well.
