Tip: A nice software for screen captures 2

I was only able (or rather, willing) to do the cool, long screen captures on my previous post because of Easy Screen Capture And Annotation—a nice and full-featured software that allows you to capture the entire content of a scrollable window, among many other things.

It’s shareware ($30), but you can use it for free without any limitation other than a welcome-nag and a red-watermark when saving your image (which can of course be easily bypassed by copy-pasting your capture to another graphic-editing program). Very useful if you ever need to do serious scren-capturing.

We have met the enemy, and it is us 2

[Vernor Vinge] added a third [future] trend: “The great conspiracy against human freedom.” As novelist Doris Lessing has observed, barons on opposite sides of the river don’t need to be in cahoots if their interests coincide. In our case, defence, homeland security, financial crime enforcement, police, tax collectors and intellectual property rights holders offer reasons to want to control the hardware we use. Then there are geeks, who can be tempted to forget the consequences if the technology is cool enough. Vinge quotes the most famous line from the comic strip Pogo: ”We have met the enemy, and he is us.”

Vinge’s technology to satisfy these groups’ dreams is the Secure Hardware Environment (She), which dedicates some bandwidth and a small portion of every semiconductor for regulatory use. Deployment is progressive, as standards are implemented. Built into new chips, She will spread inevitably through its predecessors’ obsolescence.

This part is terribly plausible. It sounds much like the Trusted Computing Platform, implemented in Intel chips and built into machines from Dell, Fujitsu-Siemens and others. Most people don’t realise their new computer contains a chip designed to block the operation of any software not certified by the group. Now enhance that and build it into RFID chips, networked embedded systems, shrink and distribute as “smart dust”. All are current trends or works in progress.

Geeks are willing to fight Trusted Computing on the grounds that it could be used to block open-source software or to enforce draconian digital rights management. But what if accepting it meant less visible security, less bureaucracy, even slight profit? She automatically sends taxes, enables much less noticeable surveillance and gets you through security checkpoints with no waiting. There’s less crime, because legislative reality can be enforced on physical reality. Fewer false convictions. Make regulation automatic, and it seems to go away. New laws can be downloaded as a regulatory upgrade.

Azureus: 3d View 2

Except for its nasty tendency to crash unexpectedly (great strides have been made, but it still does it once in a while), Azureus is pretty much the BitTorrent Client. My favorite thing about it (and this seems to be a pattern of open source projects) is its extensibility. There’s everything from a Flag plugin (to get a kick out of how international piracy is!) to a Web (HTML+JS+CSS) UI to the program.

But my favorite plugin is far and away 3D View—a dense, beautiful 3d representation of the torrent process (really, just the standard swarm graph writ 3d). Like the 12/60 clock, it comes with no instructions but it doesn’t need them. If you’ve read anything about how torrents work (and you should!), everything will fall into place after some staring. Its pure infosight—real-time infoporn of the best kind1.

1 Which reminds me: I heard somewhere today that “there is no such thing as bad porn, there’s only better porn.”

An easy way to create your own file format 2

I stumbled upon the .CBR extension some days ago and it was interesting to read its description, via filext:

This is a renamed .RAR file and can be decompressed with any .RAR file utility. The CDisplay program displays the comic book images so it is useful to use for this particular .RAR archive type.

Think about it, to create the ultimate comic-book format you simply wrap together some images (GIFs, JPGs, PNGs) and some (optional) introductory text (a .NFO or a .TXT) in a .RAR file and rename it. That’s it. A batch of pictures has been converted into a black-box, into a comic book. We’ve reified a comic out of thin pixels. That’s all CDisplay needs to let you seamlessly experience those images as a comic, but you could get as baroque in your specification of a file format as you like. For, say, a hypothetical .BIO file-extension used to store people’s biographies, you would specify a .RAR wrap of that person photo (that must be named, say, “mypic”, and must be a JPG), one photo as a kid (named “kidpic”), one photo of each parent (“mompic and “dadpic”), a curriculum vitae (“vitae”, must be a .TXT file),... you get the picture. Half of the magic, of course, resides in the reading-program, but that’s the easy part.

Here are two extra, contradictory advantages of creating file-formats thru .RAR wrapping:

the tying is loose
The elementary constituents are still available to anyone with a .RAR decompressing utility.
the tying is tight
You’re using a compression format after all, so you are probably saving at least a couple of bytes (though the time spent decompressing things on the fly could easily turn this into a disadvantage).

What struck me about this file-extension thing was how such a seemingly low-level nitty-gritty construct as a file-extension can be blackboxed mostly thru the high-level path of drag-and-dropping icons to WinRar.

  1. Given a sufficiently complete Beatles discography, every song will include at least one song from the Beatles among its best-acoustic-match recommendations.

Oh, the beauty!

I’m on the verge of screaming. The thing I’m going to tell you about is that good.

Even though I’ve got 9,165 songs in my library—my collection exploded some months ago when I started donwloading entire discographies (which is a brave new way of listening to music)—I find myself falling into the same old ruts, much to my chagrin, with only the occasional shuffle surprise showing me something unexpectedly good.

Enter Predixis MusicMagic Mixer, a new function of the just launched Winamp 5.21. There are detailed instructions of how to use it here, but it’s all incredibly simple. Basically, after letting MusicMagic acoustically analyze all your library, you can now select any song and ask MusicMagic to generate a list of best-acoustic-match recommendations. It’ll surprise you. This thing is so sufficiently advanced it’s indistinguishable from magic (there’s a beautiful relevant eemadge on the statistical process behind this). I can’t stop using it, I’m looking at my music library as I’d never been able to and, my god, it’s full of wonderful songs!
