Syslogd Overwhelming Your Computer?

If your Leopard (Mac OS X 10.5) system is unexpectedly sluggish, logging might be the culprit. Run Activity Monitor (Applications/Utilities/ folder), and click the CPU column twice to get it to show most to least activity. If syslogd is at the top of the list, there's a fix. Syslogd tracks informational messages produced by software and writes them to the asl.db, a file in your Unix /var/log/ directory. It's a known problem that syslogd can run amok. There's a fix: deleting the asl.db file.

Launch Terminal (from the same Utilities folder), and enter these commands exactly as written, entering your administrative password when prompted:

sudo launchctl stop

sudo rm /var/log/asl.db

sudo launchctl start

Your system should settle down to normal. For more information, follow the link.

Lytro Promises to Revolutionize Photography

Send Article to a Friend

By recording and processing the direction of light rays entering its sensor, the forthcoming Lytro camera promises to provide previously impossible features, such as the capability to focus on any part of a photo, at any time, or even bring an entire photo into focus at once. The camera isn’t slated for release until later in 2011, but you can play with refocusing photos and read more about the technology on Lytro’s site now (the picture gallery requires Flash on a Mac, but does work in iOS via HTML5).favicon follow link

I just scanned Dr. Ng's thesis, what a beautiful piece of work! I frequently cope with blurry photos and after-the-fact sharpening algorithms. What a wonderful breakthrough this is!

The New York Times has a nice article about Lytro too.
It's worth mentioning that the interactive aspect of the gallery shots doesn't exist if you use a Flash blocker such as the "ClickToFlash" extension for Safari. It's not obvious that there's any Flash content in the page, so you have to right-click and select "Load All Flash".

Otherwise, you'll be left scratching your head for a while - like I was - wondering what the fuss is all about. :-)

Interestingly, if you view the site on an iOS device, it uses some sort of HTML5 approach for the picture gallery. It's not great, but it sort of works, even without Flash.
