Inside Google Mini

AnandTech has a great little article on the inner workings of Google’s search appliance, Google Mini (a rackmount server which indexes your intranet). I knew for some time that the device existed, and I’d always been interested to know what’s inside and how you configure it. It’s worth a look if you’re curious. For all the Google related posts I do, you’d think by know I would have a dedicated category for them…

Tagging Standards

Sites like del.icio.us organize data through the use of tags, which I think is a brilliant idea. However, I disagree with the occasional comment lamenting the lack of tagging standards. I think the absence of a standard encourages a diversity of categories, bringing in more related content that would not otherwise be found.

The idea behind letting users tag their own content goes beyond simple per-user categorization. The theory is that, when enough users have tagged the same piece of information, it should be possible to find similarities between tags and produce an “average” list of tags for that data. While some users may append not-so-common tags, if enough do, the popular ones will rise to the top with the rest and create a new commonly used tag.

I’m wondering, though, what cutoff should be used to gauge when a tag or grouping is “popular enough”? And what tag sample size is necessary to determine that, as well?

Ultimate Xbox HD Pack

While scouring Google for an image, I ran across this fantastic schematic of a way to get nearly every possible audio/video output out of the Xbox. It represents the bottom of the Xbox motherboard, where you would solder wires to the Xbox AVIP connector (the inside back of the Xbox A/V port). Using switches, you can control the video modes and get just about any format video you could possibly need from the Xbox.

SmartJoy FRAG Insides

I recently purchased an Xbox SmartJoy FRAG PS/2 adapter to try it out, with the hopes of gaining some extra precision in Halo 2 (which I play less and less as my interest in Xbox modification grows). The SmartJoy does more than just connect the devices together — it actually emulates the signals an Xbox controller would be sending when you use the keyboard and mouse for movement. It allows you to play games on the Xbox as if it were a desktop computer game, moving around using the WASD key setup and mouse clicking for firing. While my long-range shots in Halo became much more accurate, close-combat and vehicle control suffered greatly. For now, I’ve switched back to my standard Xbox “S” controller.

Because I was curious how it worked, I opened up the SmartJoy to see what makes it tick. It’s nothing more than a Cypress USB chip and a programmed PIC microcontroller. The USB chip speaks the proper protocol to the Xbox (as the controllers and memory units are all just USB devices in disguise), and the PIC handles key programming and PS/2 interfacing. All in all, it’s a pretty neat little gadget, but not quite worth the $35 plus shipping from Hong Kong.
