If you and your ISP both use a Windows system, turning on "software compression" (and don't forget to turn off the modem's hardware compression) basically gives you mod_gzip on ALL your incoming AND outgoing data.
A drawback used to be that the server at the provider side was often overloaded, so I set up several "accounts" to switch between hard- and software compression with and without proxy. Now that my ISP is no longer "free", I haven't seen the server become overloaded any longer, so I use software compression and their proxy all the time. HTML and text download at 20kB/s over a 48kbps connection. Off course, there's no gain in already-compressed content like images and audio.
So I'm waiting for some dude to hack it and have the car follow you (or any target of choice) around like a puppy, or just drive it with a PDA, wristwatch or whatever . . . 007 eat your heart out:-)
Speed does make a difference, but slower is definitely NOT neccesarily better. Writing at 1x in a 48x burner guarantees you the worst quality you'll be able to get. Both drive and media were designed for much higher speeds.
For example, this article contains a nice analysis from the 12x days.
Also, don't be confused by pits: The LENGTH of the pit is the data. The pit can be 3 to 11 um long, and encodes 3 bits (8 values) into a single pit. The space between the pits doesn't matter much, it just cannot be too large because the laser has to have pits in order to follow the spiral.
Looks to me that you only need to upgrade when either:
You use basic authentication in combination with multi-threading mpm on UNIX AND you're afraid of DOS (authentication after attack will fail for everybody until restart)
You use mod_dav (I haven't got a clue what that mod does) AND don't like to see your server crash after an attack.
It does seem like a good idea to cure stuff, to enhance intelligence and all that good stuff. But i'm afraid all that we'll get is genetically engineered soccer players who excel at soccer but are crap at stuff that matters.
Because open source software writers cannot afford a multimilion dollar project to get a USB6.1 port in your left ear, while silly sports event sponsors can...
Most of the windoze rendering is still 2D, but that does not mean it isn't accellerated. In windows, you don't need to use 3D functions for alpha blending, interpolation and such. DirectDraw (the 2D component of DirectX) takes care of this. It also lets you render directly into video memory, using whatever accelleration possible (e.g. DMA controlled blt-ing, very nice for movie rendering and such...).
The limiting factor in Windows' Windows rendering is still the GDI. That's why a GeForce4 isn't really much faster in this than a TNT, despite the bigger memory bandwidth. Using GDI+ instead (just a dump-this-dll-somewhere) allows hardware accellerated interpolation and stuff like that using DirectDraw.
To upgrade my 2.0.44 box, I'll have to bring it down... So it's better to wait for the first attack and when it stops, upgrade it. It will be down only once then.
Maybe i'll compile the 45 version, and install it automatically when the current httpd exits...
Think about it. If you dialup with a windoze machine to a windoze machine, you get "software compression" (a tad bit better than what's built into the modem).
If your provider has a proxy supporting HTTP/1.1 and you're using a 1.1 browser like Lynx, Phoenix, or IE, your connection to the provider is already persistent. The browser will typically open 2-4 TCPs to the proxy and keep them alive at all times. Even 1.0 browsers can keep-alive connections, though they lack a few encodings to do this for server-generated (content-length unknown) content.
Too bad the servers at the provider are so overloaded that using the proxy actually lowers performance...
Web designers can do a lot more on the performance than this kind of software. For example, putting a 1-week expiration time on button/icon images will instruct the browser to not even check for a newer version during that week. (mod_expire is a must...)
...Windows server, then you'd better just pony up the $100-300 for a real monitor... because you're going to be spending a lot of time sitting at the console fixing broken Microsoft crap.
Actually, you will be going to notice that most configuration dialogs won't fit on the 234 pixel wide screen...
I don't mind dragging my 15 kg desktop to a LAN party, but I do mind carrying my 24 kg Iiyama around, i'm afraid i'll drop and break it.
But the screen is a bit small for my taste. How about recycling an old laptops TFT screen? I have a defunct laptop with a perfectly good working TFT screen. I'd love to stick its display to the case with doublesided tape. But I have no idea how to wire it, or what kind of video card I could use for this. Any comments/links on that?
These units will be slammed into desktop machines before you can say "hamspamandeggs". Joe sixpack will think that his video editing will go faster with this drive, the fact that the 10k rotation won't help (bulky) data transfer speeds at all will not appeal to him (or her, if it's Jane Average).
Politics and profit margins were the only thing keeping 10k drives away from the mass (read: IDE) market. Since 90% of the 7200 drives are IDE units with a TI IDE-to-SCSI convertor chipset, I expect the 10k drives to go the same route soon now. If they aren't already.

We could save the environment, we could find a cure for cancer, we could ...
NO! Let's use it to play games!

Hmm, just a DOS vulnerability.

Just add some comments to your program!

I have a very vivid image of Saddam sitting behind a Gates powered laptop that goes:
"New hardware found: US Laser Guided Missile"
And then asks for DirectMedia 8 to be able to get a live cam view
Yeah, right. For the server market.
