64 Bit Computing
Most computers people use nowadays are 32 bit, but 64 bit computers are becoming popular. A 64 bit computer's fundamental instructions can work with twice as much data in about the same amount of time. This translates to faster MP3 encoding, higher resolution video encoding and playback, and increased precision (correct to more decimal places). I have been playing with Microsoft Windows XP 64 bit edition on a new AMD 4800+ computer with tricked out graphics (SLI'd NVIDIA 7800's) (my 3DMARK05 is 14571 (that's high!)). This AMD chip is also dual core, which means it has two CPU cores that run mostly independently in parallel.
Now, a 64 bit computer and operating system can usually run older 32 bit programs, but certain programs and hardware depend upon drivers. Most drivers are still 32 bit, and 32 bit drivers can't easily be installed on this Windows XP system. This means my good sound cards and video cams aren't yet working. Further, several network drivers I use for sneaky purposes aren't yet compatible. I suspect I'll have problems with DVD burning too.
So, if you want to be cool and take advantage of all those 64 bits, you have to be 64 bit end-to-end, which means you need the 64 bit operating system, the 64 bit drivers, and 64 bit applications. Since I'm cool, I've installed 64 bit Java (FINALLY, IT IS FAST ENOUGH!), Oracle 10g Enterprise 64 Bit AMD Edition, and a few other programs. It's going okay, but I'm not super happy about the availability of drivers (I wanted to use this box for video encoding and streaming too). It's REALLY fast though. Java installed in about 1 second.
Something odd is that vendors are taking their sweet time releasing drivers. It seems that if you want to do audio and video, it's taken over a year for drivers to start coming out in 64 bit form except for some ultra-expensive super-pro stuff. Even things like those Wacom graphire tablets are not 64 bit compatible (but their super expensive tablets are). I think the vendors are not releasing the drivers so you are forced to buy 'new' products from them. Take Logitech for instance -- big company (mice, keyboards, webcams, etc...). They haven't released a single 64 bit webcam driver in a YEAR.
Further, as I found out, LOTS of people are having HUGE problems with not only 64 bit platforms, but also the new expansion card format PCI Express that new PC's are including. These two technologies are fairly new, and it seems they haven't been perfected yet.
So, since I couldn't get my good soundcard to work on this new box, I decided to route audio through the gigabit LAN via 'Jack', which is a cool program that lets you essentially select speaker outputs on other computers on your network. Since my house is networked, and there are lots of speakers and amps in the house, I can select any one as an output through the network. Jack is free, and runs on Linux, and OS X. I tried it through the wireless network, but it was glitchy. If you have a LAN, it's a great way to have one good stereo, and route all your computers audio to it via the network.
CORONAL MASS EJECTION ALERT
Oh, and go for a drive to the country tonight. Due to a large coronal mass ejection, you might be able to see the aurora!!!! (also check the sky clock at the bottom of this page) - click the link and it will tell you how clear and dark the night sky will be where you are).
OH, and DARN YOU FEDEX
I received a tesla coil in the mail today, but it was pretty bashed up. A transformer was ripped off the board it was screwed into, and was bouncing all over the circuit board during shipping. Instead of millions of volts, I get a lame duck. Now I have to fix it, which is FUN! I don't think it's possible for FedEx to actually treat packages worse. What a freaky company.
