Extract Directly from Time Machine

Normally you use Time Machine to restore lost data in a file like this: within the Time Machine interface, you go back to the time the file was not yet messed up, and you restore it to replace the file you have now.

You can also elect to keep both, but the restored file takes the name and place of the current one. So, if you have made changes since the backup took place that you would like to keep, they are lost, or you have to mess around a bit to merge changes, rename files, and trash the unwanted one.

As an alternative, you can browse the Time Machine backup volume directly in the Finder like any normal disk, navigate through the chronological backup hierarchy, and find the file which contains the lost content.

Once you've found it, you can open it and the current version of the file side-by-side, and copy information from Time Machine's version of the file into the current one, without losing any content you put in it since the backup was made.

Algorithmic Animation and El-Fish

There are several interesting things about El-Fish, reviewed in TidBITS-231. Its fish breeding capability, which follows genetic rules, is fairly well-known. Less known is something which may in the end prove more important, namely that its animation is algorithmic and not frame by frame. This is why it is so life-like. The program was developed in Russia. The animator emigrated to the Boston area where I met him in a computer store. He explained and demonstrated for me how he had developed mathematical descriptions of the possible motions. This was necessary because the program will breed incredibly odd-looking, impossible fish, making frame by frame animation impossible. Because the fish move by rules, they essentially choose where to swim from moment to moment. To prove this wasn't a fluke, he then showed me a program of horses trotting which he said he put together in a few days. It was eerie to watch the horses run next to each other, cross, turn away, etc. While much animation is moving toward captured motion (optically, magnetically), the potential of algorithmic animation is vast. By the way, he hated the straight at you / away from you azimuths (because they look squashed) and was upset that they were added to his work. I hesitate to tell you how little he was paid.
