Wanted: A PowerPoint Shrinker

I've noticed that you can often substantially reduce the size of PowerPoint files simply by saving the same file to a new filename. I just did this for a lecture on social networking theory, and it went from 7 megs to 3.5 megs.

I'm trying to guess why PowerPoint does this, and not coming up with any good ideas. It can't be for undo, since PowerPoint eliminates your undo queue whenever you normally save. It might be for faster saves, though I never notice any difference between saving normally and saving to a new file.

At any rate, one thing that would be really nice would be something that did this automatically before emailing it out or posting it on your web site, just imagine the savings!

Have you tried disabling "Fast Saves"? Go to Tools->Options...->Save tab, and uncheck "Allow fast saves". That will probably keep your file size down.

Ah thanks. I wonder what the goal of fast saves is? Does it actually do, well, a faster save, especially given the performance of today's machines?

How to Fix a Jammed Toyota Camry Trunk

This problem needs a higher pagerank, so I figured I would post the solution here. If your Toyota Camry trunk won't open, one possible reason is that it is set to valet mode. Valet mode means that you cannot open the trunk using the release lever inside the car. To set valet mode, you put the key into the trunk lock and turn it counterclockwise. You will know that your trunk is in valet mode if the lock is horizontal rather than vertical, and if you cannot open the trunk using the lever near the driver's seat. Of course, a problem is that sometimes the Camry can get stuck in valet mode, such that you can't use your key to get out of it. (You can see how I spent part of my Sunday morning ...) The solution turns out to be WD-40 . Spray some WD-40 on your key and on the lock. Put the key in, and jiggle it around, and happiness ensues. From an interaction design perspective, it sort of makes sense to have a valet mode. After all, the point of having a valet key is to limit the...

Web 2.0 and Research

I've been chatting with many of my friends and colleagues about an issue that's been bugging me for a while, namely whether academic research has any role to play in the emerging Web 2.0 . I've been slowly coming to the conclusion that the answer is not much. I had a similar discussion with other researchers at HotMobile a few weeks ago. When the web first came out, pretty much every systems researcher ignored it because it was so ugly. The web was not very sophisticated in terms of distributed systems, HTTP lacked elegance, HTML conflated many different ideas, and so on. There were also not any really new ideas with the web, as evidenced by the fact that Tim Berners-Lee 's first paper on the Web was (probably rightfully) rejected from an ACM conference on hypertext. I'm sure one thing that really irked researchers about the nascent web was that it completely ignored the large body of work in hypertext and distributed systems that had preceded it. Even in 1997, as ...

[Research] Famous Rejected Papers

I've always thought it would be fun to compile a list of famous rejected research papers, ones that later turned out to be highly influential. For example, in My Life as a Quant , the author tells the story of how the famous Black-Scholes paper (which describes how options should be priced) was rejected several times. The work eventually led to a Nobel Prize in economics. (Yes, I know, there technically is no Nobel Prize in economics). Then there's George Akerlof 's work on asymmetric information . I don't recall exactly, but I think the reviewers thought it was too simplistic. It also led to a Nobel Prize in econ. And then there's Tim Berners-Lee 's original paper on the World Wide Web. He describes his experiences in his book Weaving the Web . I think it was submitted to a hypertext conference, but was accepted only as a demo. I'm guessing reviewers didn't see much novelty in the work, which probably was correct from a research perspective.
