The distinction between internal and external drives is partally due to electrical problems with making external drives, at 1.5Gbps a 1m cable looks a whole lot like a transmission antenna....
Yes, SerialATA does have provisions for backwards compatability between the current Gen (whatever that may be) and earlier Gens, There are of course situations where backwards compatability cannot be maintained, but they're moderatly few.
Standard disclaimer applies, I'm not an analog engineer, nor am I an expert in Serial ATA, I just work for a company that does a lot of work in Serial ATA
Correct, Gen1 doesn't daisy chain. The HBA's we have here in the office are set to a two port configuration, but can be made as big as 8 ports.
Gen1 serial ATA is also a strictly in-box connection solution.
It does have plenty of benefits over ATA and SCSI as they stand now, hot-plug, blind-mateable connectors, really thin wires, the wires you see in all of the demo pictures are test wires, we'd always hoped to have thinner wires than those on the end product, but at this point those cables may become standard.
The connector is also tiney, we have a drive here that looks like a standard ATA drive on first inspection, but if you look closer, you notice the jumper block is only one row of pins, and that where the other row should be is a serial ATA connector.
The inital plan for Serial ATA involved features like daisy chain, and a few others, but as the problems started to arise in development of the spec (as they always do) it was decided to push most of them back to gen2.
Oh, I forgot my favorite feature, with Serial ATA, the legacy power connectors will eventually disappear, the new power connector is blind-mateable, just like the serial cable, and doesn't have most of the problems assosiated with "Molex" power plugs (ability to insert backwards with sufficient force, variation in size causing some connector/drive combos to be nearly impossible to connect dis-connect, etc).
Also, remember that when people talk about the 1.5Gbps speed, that each connector has the full bandwidth available to it, unlike U160 SCSI or ATA/133, and that it's also the Gen1 speed, Gen2 runs twice that, 3Gbps. Well, back to work for me.
I run 7.1 and had problems with logrotate creating thousands upon thousands of files under/var/log/news and/var/log/mail. It was zipping the old logs and keeping 4 around named logname.x.gz where x was 1-4. Well, in those two directories, it didn't seem to understand that it shouldn't rotate it's own.gz files. I finally noticed this after probably 6 months. It took me probably a hour and a half just to delete them all... there was far too many for a simple rm logname.1* -f or something like that, had to go through and try to pick out small enough chunks to make it work. I noticed this happening because logrotate was taking 100% cpu for FAR too long.... That might be your problem, also with that many files slocate would probably take forever as well...

SCSI can go up to 320MB/s but that's shared among all of the drives on the chain. SerialATA gets rid of the whole chain idea, it's a point to point connection, so while it's only a 150MB/s link, it's not shared between drives.
You also need to ask, what is the peak transfer speed of the fastest HDD around, right now it's around 60MB/s if I remember correctly, not even enough to max out ATA66, the only time you need ATA100 is if you're using the slave channel. So while 150MB/s seems slow compared to the fastest SCSI connection around, you never have to share it with another device.
-Ted
As a matter of fact, yes it does. One of the output plugins, Disk Writer, has been included with Winamp for many versions now. Basically it takes the wave data it would've sent to your sound card and sends it instead to a file on the hard disk. This allows you to convert pretty much any format Winamp recognizes (MIDI, CD, etc.) to a.wav file.
Only one problem with this. The CD player plugin only tells the CD to play through the cable connecting the CD drive to the sound card. The same way every other piece of CD software works. Don't believe me? Either try ripping a CD to a wave with the DiskWriter plugin, or just look at the osiliscope part, notice it doesn't do anything? that's because Winamp never sees the bits fly by, it only sends commands to the CD drive.

Gundam: action based sci-fi that spawned several series
Having watched Gundam Wing all the way through riecently I have to say that it deserves more than just that for a review. While I can't speak for the other's in the series, as I have yet to watch them, I got hooked into Gundam Wing on the CartoonNetwork back when it started. The entire show is visually stunning, and the plot is just as good. At times it doesn't make much sence (especailly if you watch the cut vs. uncut versions and try to notice the differences. I guess saying "I'll distroy you" is much more sutable for childeren than "I'll kill you", but back on topic). By the end of the series everything is explained. I really appriated the continuity of the charchters, while they all evolved through the story, none of them ever did anything that they shouldn't have, even if I as a viewer wanted them to.
Gundam W is the best Anime I've seen, although I have yet to see Neo Genesis Eveangelon, which I've been told is atleast as good. -Ted
There's been some discussion about an alpha channel in X on the e-develop list for some time. Your idea of extending the xshape extension to include a 8 16 or 32 bpp alpha mask was discussed, the problem comes when a client tries to get information about their window, and their window happens to be alpha-blended in with 16 other windows... I personally think that it could be done through the xshape extension, but I'm not under any pretence that it would be easy. Nor do I know anything about X programming, otherwise I would go and do it myself. -Ted
uptime isn't the inverse of downtime, as odd as that may seem. It's quite possible to have very little down time but not years of uptime, it seems to me that in most cases 1 minute of downtime is quite acceptable when it allows you to fix problems. I think that the 45 seconds worth of reboot time to get important new features in the kernel is well worth it, even if it does ruin the whole uptime thing... I personaly think that the best way to measure uptime isn't in hours or years, but in percentage. -Ted

I'm not going to cripple MY operating system just so some person who buys a computer from circut city can use it in linux.
If you aren't able to recompile the kernel and remove support for hardware like winmodems, I don't think you really have the right to refer to Linux as "MY" operating system. That being said, I'm all for Linux support for any hardware out there, the more capable Linux is of replacing Windows, the more likely it will. Near as I've seen the only remaining point of contention is office suite applications. -Ted
How long ago was it that CD's were pressed, so you couldn't write them because they just didn't work that way? I dobut that this technology would take long to become writable, if I remember right one of the companies was working on making ones of these that use AFM's to write it in the first place.

How fesable is it for him to make backups of 3+gb worth of data that's all on a remote server.

His link is probably faster than that, but 3gb is a lot to be backing up like that. I'm sorry for his loss, and sorry that the admins at Harvord are being such morons. -Ted
I agree completly on SP not just being for kids, I had an english teacher once who absolutly loved the show, I can remember many an afternoon we wasted watching SP tapes when she ran out of things to teach. I haven't watched it in ages, but from what I remember a lot of the jokes would go right over the 11-14 year old's heads, heck I remember some that went over my head. but what the kiddies really miss is the satire. I personaly believe that childeren under the age of 15 or 16 shouldn't watch SP at all, I don't think any of them really understand the satire, they just see toilet humor. -Ted
