Auto Dial

Filed under: Research,Usability | ,
― Vincent Gable on June 28, 2008

Today, most people I see making phone calls use cellphones. As near as I can tell, every time they call someone they know, they do it using their phone’s address book, instead of keying in their a ten-digit “telephone number”. It’s pretty obvious why. Nobody wants to have to memorize ten-digit numbers. And we think of people by their name, not some number.

This was not something that was hard to predict. Rolodexes have been in every office for decades, because people want to look up people by name, not number. Only recently has software supplanted them.

I was very surprised when I found this unknown invention from the late 1930’s

A NEW desk telephone directory not only finds the number you want but actually dials it for you. All you have to do is slide the knob on the face of the device, called an Auto Dial, to the name you want, then press the small lever at the foot of the machine. When the lever returns to its normal position, in five or six seconds, your call is made and you pick up the phone.

The Auto Dial was invented by a German before (World War II). The only sample in (America) is owned by Alfred Altman, President of the National Dairymen Association. The machine can handle any 50 telephone numbers desired by the user, and changes can be made at will.

The signals can be made up of any number of letters and digits, according to the system used in the local exchange. The regular hand dial on the telephone can be used in the ordinary way when the automatic device has been attached.

What an improvement over memorizing and/or dialing a number! We all have these devices built into our cellphones today. Frighteningly, the original appears easier to use then my cellphone’s “Address Book”.

So why didn’t this invention catch on half a century ago, not just a decade ago? I don’t know. I can only speculate, and I don’t think there is value in writing uninformed guesses down. But understanding why the Auto Dial was never popular is probably very instructive.

The Heat Barrier

Filed under: Research | , , , ,
― Vincent Gable on June 27, 2008

Technology improves at an overwhelming pace. The prospect of exponential growth has some people making fantastic predictions. Eg. “In 15 years, life expectancies will start rising faster than we age”.

I’m a big believer in the power of human invention. But I stumbled upon a somewhat sobering magazine article a few days ago.
CAN WE CRASH THE DEADLY FLAME BARRIER? (Oct, 1955)

Fly a plane fast enough and friction will melt it. Can we “put out the fire?”

As near as I can tell, the answer is no. Worse, maximum airspeed has declined over the years. For example, the absolute air-speed record of 2,194 MPH was set in 1976 with a currently retired aircraft. In 1976, we came up against the heat barrier, and could not break it. Since then, we have also retired the only two models of supersonic transport aircraft to see active service. The minimum time to cross the Atlantic is higher today then 20 years ago.

Now it’s safe to say that miles per gallon of fuel, and speed / gallon, have increased since 1976. This is almost certainly of more practical importance to the world. But I think it’s worth noting an example of a purely-technological dimension that has regressed with time. Not everything in technology doubles every two years.

Nobody Likes a Pimp

Filed under: Quotes
― Vincent Gable on June 21, 2008

On a personal note, recently my shrink said to me, “Hey, Wil, why don’t you drop the pimp act? Nobody actually looks at show-offs and thinks, ‘Oooh, I like him.’ In fact, everyone resents them.”

This made a lot of sense, so I’m officially renouncing my phony pimpitude.

Modern Browsers

… What struck me watching these (WebKit) demos is that you could build a really slick web app UI using stuff like the canvas tag, SVG, and advanced CSS. Yes, none of this stuff works in IE, and IE still has massive market share — but not among the sort of people who adopt hip new web apps. The combined market share for, say, Firefox 3 and Safari 3 is larger than the overall market share for Mac OS X. Plenty of developers write desktop software that only works on the Mac — why aren’t more people writing apps web apps that only work in truly modern web browsers? The first one to do it is going to be a sensation.

I didn’t have a sense for how far behind IE lags, historically and today, until I saw this compatibility table (via Toby Jungen),

Backup

The single most important thing any company or individual can do to improve security is have a good backup strategy. It’s been true for decades, and it’s still true today.

Here’s a good article on backing up data.

Hold off on Upgrading QuickTime to Version 7.5

Filed under: Announcement,MacOSX,Tips |
― Vincent Gable on June 16, 2008

The QuickTime 7.5 update appears to have broken sound in VMWare Fusion, and also in some code I’m working on. I will know more once I have fixed the issue in my own code. But for now, I advise waiting to update QuickTime to version 7.5.

UPDATE 2008-06-19: problems in my code solved. Basically I was specifying a bit-rate for a compressed audio stream, and QuickTime expected it to be 0. Earlier versions of QuickTime didn’t care, but 7.5 was more strict. Also, the VMWare problems have been fixed.

Bring an Extra Battery for WWDC

Filed under: Programming,Tips | , ,
― Vincent Gable on June 11, 2008

I was chatting with a saleswoman at the San Francisco Apple Store, a few blocks from where WWDC is being held this year. According to her, the top things people wearing WWDC badges bought from the Apple Store are (most popular to least popular):

Laptop Batteries. Specifically, 15″ MacBook Pro batteries. This is apparently #1 by a wide margin. It’s what I was in the store to buy. I don’t normally carry a brick spare battery with me, because in my experience you can’t rely on it being charged when you need it. But at WWDC, there are stations which charge your battery while you work, so you always have a fresh battery ready to swap in. You can go the whole day without plugging in!

Power Adapters. (I guess battery chargers are not a panacea)

Laptop bags/backpacks. This one is funny, because Apple gave out a laptop case to every WWDC attendant. I’ve always thought that giving out laptop carriers to people at a tech conference was a bad idea, because everyone there already has a laptop and a laptop carrier that fits them. Mass-produced swag is probably not going to be better quality then something a nerd picked out for their computer. More people purchased a backpack then a smaller brief-case-sized carrier (presumably so they could haul around extra gear).

So when you go to WWDC, bring an extra battery. It’s the number-one thing attendees (including me) regretted not bringing so much that they ran out to buy one.

Michigan Flyer

Filed under: Tips | ,
― Vincent Gable on June 8, 2008

I’m writing this on Michigan Flyer 344, in transit from East Lansing to the Detroit Airport (DTW). So far, I’m happy. Wireless internet is available on the bus, and there are maybe one or two power-outlets (125 volts @ 60Hz) if you look carefully. So far, it’s been a better experience then catching a connecting flight to DTW.

The verdict so far: recommended.

UPDATE: So on my return trip, there was no internet. I suspect this might have been because the lights and TVs were turned off, but I am not sure. Also, I had to wait around 3 hours for the bus to show, so I didn’t get home until 1 AM. Not good. On the other hand, no delays or rescheduling. The airline industry is in a crisis right now, and about one in four flights are delayed. Busses are more predictable.

UPDATE 2008-10-19 5:48 AM: No internet this time either; the driver said it went out last night and hasn’t been fixed yet. The power-outlets still work however. (And during a stop I was able to check my email over hotel-wifi that leaked into the bus.) This time the bus-schedule matched up very well to my flight schedule.
