Of course the bluetooth kit that comes with this board is really tiny, which makes me wonder if you might be able to integrate it into a small remote device... But anyway, if a computer upgrade is on the horizon, have a look at this Epox board review and the bluetooth gear it uses."

Fact check on bluetooth volume (Score:4, Informative)
"In 2Q02, 802.11b hardware shipments grew 15%, totaling 3.9 million units." [216.239.35.100] 3.9 million x 4 quaters/year = 15.6 million/year if volumes are at least flat for the next three quarters. x 365 = 5.7 billion bluetooth devices produced per year? I read in a magazine recently that the total number of computers ever produced is expected to reach one billion in the next few months.
Poking around the internet, all I see are projections that perhaps bluetooth unit volumes will catch up to 802.11 this year. "It is not fair to run comparisons between Bluetooth and WLAN regarding the number of chips being shipped or expected to be shipped for either technology. Because of its price and the type of products where it is going into, Bluetooth will soon surpass 802.11 chip shipments but dollar volume might still be smaller for some time." [mobileinfo.com]
"Our annual Bluetooth study predicted Bluetooth chipset shipments would rise from close to zero in 2000 to just over 10 million units in 2001, and the year will end not far from this figure." [wirelessdevnet.com]
Could you please post a reference for your claim that "more bluetooth devices are made each day than 802.11b in a year" or a retraction? Thanks in advance.

Such as you ask? I have multiple KVMS switches for handling multiple monitors connected to multiple systems. These all use standard VGA and serial/PS2 ports for mouse/keyboard. One KVMS can run $200-$1000 easily - and that's before buying all the cabling for them. Heck, a few of 'em still use the large DIN connectors for keyboard and 9 pin serial for the mouse.
My printer likes Parallel and I like my printer - it works just fine. Now I'm supposed to drop another few hundred bucks on a printer?

But anyway, USB 2.0 and IEEE1394b at at least 800mbps, with multiple buses of each. I really don't want to settle for less than 1.6Gbps on the 1394.
All I really want in a computer (Hey industry types, print this out you cocks, this is the way of the future) is some really super-speedy expansion buses which can be chained out to support legacy shit if I need to, multiple AGP slots (there has to be a way to pull this off, especially what with the stupid fast chips coming out these days), a handful of PCI slots, some good fast firewire, USB 2.0, good built in audio (true 48khz with no auto-resampling except when mixing streams with incompatible rates, optical spdif with at least true 5.1, etc) and, here's my last little fever dream --
Support for as many Hammer CPUs as AMD's new bus allows.
I know it's a wet dream and no one will make this but isn't the idea of this hypertransport bus (anyone remember hyperprotocol? that was tight. hyperp++) to make it painfully easy to do SMP? So just give me a bus which sticks off the side somehow and lets me add more processor modules, so many chips per box, up to the limit of the architecture, which is something like 31 CPUs, right?
I know there's probably not much point to extending the system that way, that you would have to do something really incredible and costly to make a system like that that was done the way you really SHOULD do it. I know that you would probably have to do special optimization to actually make the most out of a SMP configuration that runs along linearly like that. Then again maybe Hammer is the holy f'n grail and I'm wrong, it would be magically fast. But I didn't really think so.
But it would have so much cool factor that as long as it didn't suck every geek with spare cash or who could whore themselves out in some way to get some loose funds would at least think about buying one. The ability to extend out to a whole goddamn bunch of processors would be the most beautiful piece of wankery ever.
I'd buy one for sure, and max it out eventually. Just make sure that the additional modules use really good connectors and support at least four CPUs per module and the modules cost no more than a motherboard. I don't think that that's unreasonable.

SATA, Linux, and Archive Storage (Score:5, Informative)
----------
Maxtor recently announced a 320GB ATA drive. This, in itself, isn't too remarkable, other than the quite large size jump. What is remarkable is that they are targetting it to somewhere that has never been specifically aimed at with ATA drives, the large corporate storage market.
About a year ago, my company was running out of hard disk space, again. We had filled up our 500GB main live SCSI RAID, and our 190GB work in process Fiber Channel RAID was looking pretty small and obselete.
For reference, we paid about $30,000 for the 500GB SCSI RAID only three years ago. The Fibre Channel RAID came about a year earlier and cost about $45,000. Support on both is over $5,000 a year.
Our main archive needs are for mostly dead storage, that is, speed is not critical, but availability is. The main archive was previously housed on a very slow 1TB tape robot. The tapes were becoming a bottleneck in our workflow, so about two years ago I designed a shell script system in IRIX to allow the files to be stored on live RAIDs without the risk of using older versions of files by accident.
This worked fine, but with the increased throughput, we also had increasing demands for more storage. Our archive has increased in size almost 100% since 2 years ago, and grows by nearly 5GB per week or more.
So, about a year ago, things were starting to get tight again. I looked at the options, and Maxtor 100GB ATA drives were out. I figured we could use Linux in this situation, and just attach the storage to the network, since speed was not critical. After some searching, I found 3ware, www.3ware.com, who makes a PCI ATA RAID controller that holds up to 8 drives and has good Linux support.
There were some issues at first, due to a hardware recall on 3ware's part, but after the bugs were worked out, I managed to build two NAS systems. These were a huge leap forward in terms of storage cost, each server cost about as much as we pay in one year of support on the old RAID systems, and were complete computers, compared to simple direct attached storage. We got 3 TB of storage for about $12,000.
These storage servers were pretty novel a year ago. Very few people had built multiple Terabyte systems from ATA drives at that point. Now they are becoming pretty common. For example, RaidZone (www.raidzone.com) makes a similar NAS (Network Attached Storage) product based on Linux. www.acnc.com is also embracing ATA as a viable platform for large RAID, though they are packaging it with special controllers that allow one to use the ATA RAID with any operating system, the OS sees the RAID as a single, directly attached storage device, through SCSI and fibre channel. This has the added benefit of allowing SCSI features like command reordering, and more robust command integrity checking.
The coming of serial ATA over the next year is serving to quickly push ATA into the mainstream low-to-mid end server market. For large data storage needs, tapes no longer offer a viable option. Linux based NAS and hardware based directly attached ATA storage are quickly becoming the de facto standard for large archival storage, at 25% or less of the cost of tapes, without the hassle that comes with the non-random access of tapes.
ATA is often viewed in the industry as a "consumer level" technology, or "not for serious use". This view is quickly becoming outdated with the wealth of new ATA based server products.
ATA in many ways has a history a lot like Linux's. It is a low cost technology, that is quickly eating away the market of more "serious" technologies like SCSI and Tape. This is the same way Linux is eating away at the old UNIX market, replacing so called "high end" servers with commodity hardware. It's no surprise that many ATA NAS products are Linux based, for an embedded system where cost is a primary concern, a Windows license would add unnecessarily to the cost, and reduce reliability while limiting the freedom of the developer to customize the system to the application.
Theere is a long history of lower cost disruptive technologies killing superior technologies. ATA isn't technologically better (yet). It is, however, good enough, and much much lower cost, and that's all it needs.
The lack of high speed 10,000 RPM ATA drives does tend to make it not currently viable for high speed, random access, low latency, applications at this point, such as heavily loaded databases. There is no reason a high RPM ATA drive could not be produced in the future though. In my experience, most high capacity storage needs are archival, or only require a low transaction rate with moderate to high data rates.
In terms of raw throughput, ATA RAID can easily outpace any SCSI RAID, do to the nature of the interface. ATA RAID is implemented like switched ethernet, each drive has its own channel to the host controller. SCSI and basic configurations of Fibre Channel are like old fashioned shared ethernet, ATA is like switched ethernet.
ATA is Linux's new partner in the server room. Together, they are drastically reducing the cost of operations, while at the same time, offering a much more capable solution for many common needs.
Re:SATA, Linux, and Archive Storage (Score:2)
I agree with you that IDE solutions are novel, making inroads, and are a great solution for low-end data storage. Once you reach the mid-range market, however, I really would have to suggest that you use SCSI. SCSI was designed intelligently, without any ugly hacks to work around. Many of the features are not apparent in benchmarks or low-end usage. Sometimes, you won't even see any apparent benefit to SCSI unless you're dealing with high-end or cutting-edge storage solutions! What you're missing, however, is that these storage solutions (even if it's just a simple file server with a bunch of disks (JBOD)), each disk drive has a massive warranty (5 years is the industry standard), is over-engineered (so that it doesn't fail right after the warranty period ends), and is compatible with every other SCSI storage solution ever made. Do you need your drives to be external? No problem. Do you need your disks to go into an Alpha server? No problem. What about the existing RAID setup? No problem.
IDE is a great innovation, and I'm glad that Maxtor is pushing the envelope. However, to suggest that SCSI is obsolete, except in the most demanding situation possible... ugh... I don't know about you, but I trust a Seagate Cheetah a lot more than a Maxtor DiamondMax. Sure, you could load up all the brand new servers with low-end motherboards, generic RAM, and IDE hard drives, but I'd be a little wary of depending on them when the site gets slashdotted.

You make some valid points, but my main point was one of cost-efficiency.
Also, with PCI 64/66, triple Ultra 160/320 is pretty silly. A 8 disk ATA contoller already maxes out said bus, so does a single Ultra 320 channel. Until we get faster busses, all that speed is wasted anyway, the only thing you eliminate is some device contention, something that doesn't exist in SATA/PATA one-disk-per-channel controllers.
Also, about "low-end", do you consider a 5-10TB RAID low-end? As I said, the only drawback is in heavy transaction loads, latency sensitive applications, because of lack of intelligent command queuing (sometimes, as I said the integrated devices that have SCSI on the outside and ATA on the inside get around this in large part) and lower RPMs.
If I had the money, I'd love to see modern ATA put up against modern SCSI in real world tests. It's a hands down winner in cost/GB, performance is not as clear, but I bet it would be "good enough" for a lot of applications, and that is what matters.
As far as your comments on reliability... I see this as more of a non-issue, since the useful life of a RAID is far less than 5 years in a lot of applications. As I pointed out in my real world examples, the cost to maintain a 5 year old RAID outweighs the cost of newer technology in many cases. Immediate redundancy is taken care of, because one can easily afford completely redundant systems, in addition to RAID on each, and still have a cost advantage over SCSI.
As far as platform independance, the ATA-SCSI hardware RAID devices take care of that if you need it. If you don't, lower cost internal solutions can be used.
Also, I don't think SCSI is obselete, I just see ATA as the disruptive technology that will soon relegate it to highly specialized applications.
In a way it is sad, I admit, SCSI/FC is a far better technology. The writing is on the wall it seems though, and cheap and "good enough" seems to have won again, just like VHS/Beta.
