I'm posting this on a Compaq Presario. WinModem is no good but a Xircom real-port 56K/10/100 card makes up for that. NeoMagic chipset is well covered now with XFree86. I really like this laptop and Linux works well on it since RedHat 4.2.
In UNIX, everything is a file, and a file is simply a sequence of bytes without any particular structure.
There are four basic kinds of files:
ordinary files
directories
special files (also called device files,
character files, or
block files)
links
Ordinary files may be ASCII or binary. Special files are the interfaces for peripherals and other real and pseudo devices. One can open, read, and write on device files and directories just as
with ordinary files, although the commands or system calls may be different for different file types.
I use 1600X1200 on the desktop at work. This will allow a way to do presentations that look the same on the laptop as I see them on desktop. I hate having to go over it again just to see what has changed when I get down to 800X600. WOOHOO .

The drive whirred, and the program handled the rest.

Well, so let me relate how Microsoft has included an ISAPI.dll as part of the FrontPage extension package/Option Pack/Visual Interdev, to "improve a hacker's experience while downloading software from your web site". I was contacted by Alf Serer (alf@at.clientlogic.com), who indicated to me that dvwssr.dll looked like it was a backdoor, and that it contained the string 'Netscape engineers are weenies!'(although, it's found backwards in the.dll). Being the curious pup that I am, I decided to take a look. Using some prior research code attempts at cracking the encoding algorithm (herein referred to as the 'weenie algorithm'), I used a test ISAPI app Alf sent to figure out what the hell this thing was for, and what it is supposed to do. Searches on Microsoft's site said it was to 'verify URLs'. However, I could not find any references to it elsewhere, and even decompilation of the various FrontPage extension applications, FrontPage clients, and Interdev clients yeilded no calls or references to dvwssr.dll that I could see; however, I was later told that Interdev 1.0 requies this..dll. Microsoft's site had dvwssr.dll down on the manifest for various FrontPage packages/installations. So, taking a peek at the.dll versions, I see that the other ISAPI.dlls that make up the core of FrontPage extensions are of version 3.0.2.1105, while dvwssr.dll is only 1.00.00.2503A. I would think that to mean it was recently introduced into the pack by Microsoft (if you don't know, FrontPage was an original program developed by Vemeer Technologies Inc; hence the _vti_ prefixes.)

I was in Desert Shield/Storm. I tried to see both sides of the Journalistic points of view, both as a person who would pay if my position were to be given out and as a news reporter trying to tell what was going on. I came to the conclusion that both can be served. Give out all troop movement and other similar information, I mean ALL of it, 48 hours after it happens.

I've got a Sony Video Walkman with a 3-1/2" LCD screen and an 8mm VCR built into. It takes camcorder batteries and one of the batteries will last about 2 hours. It plugs into a lighter socket in the car too. My kids watch movies on it in the backseat while we're on a trip. I've also got (now) an Apex 600 DVD player just because of the Macrovision deletion with that little TV in mind. I copy CDs to audio tape for use in the car, now I've got a travel collection of video tapes for use in the car. I only copy those I own on some media type, though. Now there's another way to do it. The more holes in the MPAA's story, the better.
Autorotation means putting the collective to the full down position and allowing the (now upwards vertical) relative wind create the power to get your blades up to speed so you have momentum at the bottom when you go to start your smooth and progressive deceleration, and create more momentum. When you pull initial you need every bit of that momentum and as much more as you can get to cusion it to the ground. "Real" helicopter blades are twisted from the root to the tip, some more than 3 degrees for two reasons, one so you do not get ALL your lift from the outer end of the blade (reduces coning and blade flexing) and two, so you have "positive" pitch in autorotation as part of the driving region of the blade. 6' blades - no momentum, no collective (fixed pitch) - cannot put the blades down to full flat pitch. No blade twist, no ability to get a driving region in the blades for an auto. You would have a driven and a stall region but no driving region. If you would like a deeper answer, please come over, I'm a helicopter instructor pilot with 1400 hours in them. I'll be glad to give you an aerodynamics class.
120mph, about 112 knots, 6' blades, 900rpm, still no problem with retreating blade stall. 35' blades require somewhere about 200 kts before it's a problem. I'd imagine this one would be somewhere about 400+ knots. Things would fall off (like the pilot) long before the blades shread. I wonder what a full dive into a loop would do? Hmmmm.
Stay underneath the overlying controlled airspace. 700' for most of the country (US) 1200' away from airfields and up to 10,000' for out West (where Class E begins.) The uncontrolled (Class G) airspace is made for weekend pilots who fly VFR/VMC only. Even if you're in controlled airspace, you would still come under the "no electronics, no radio" rules of gliders and ultralights. Stay the heck away from larger airfields (Class B) though. The larger the airfield the more likely there's a VFR procedure just so the ATC people do not have to talk to you. Stay in your lane and it's a piece of cake.
When I read the "No Sue-um" law, admittedly a few years ago, it was only for structures that have been in production for over 20 years. This has been on the drawing board since about DaVinci's time but this actual production would not be covered by that.
Someone already mentioned the lack of autorotational capability. Dual engines would almost be mandatory. Retreating blade stall would be a non-issue with 6' blades and a top speed of 60mph. Counter rotating blades have proven themselves already in a few designs out there. Nice "toy" but I wouldn't want to depend on it for my living. I'd much prefer a cage of some kind for minor things like birds and bugs (ever stuck your head out a car window @60 mph and gotten a bug in the eye or mouth?) The good thing it that it's MUCH cheaper than a Bell 206. I wonder how long it will take before it's regulated to death "for our own safety." Big ol' knobby tires might make roll-on landings more interesting as hovering takes a LOT of gas. "Honey?? All the other guys have one..."
The Federal Government, by continuing to accept bids by a monopoly for it's software and OS requirement, is also giving the message that it's okay to be a monopoly. There is no incentive to change if you are still getting millions of dollars from the very Government you are supposedly getting punished by.
Here's my suggestion, no Federal contract for fiscal year 00 or 01 may include a Microsoft product. Six months, a year, whatever. That would send a definite message about the Fed's views of a monopoly.

The good thing it that it's MUCH cheaper than a Bell 206. I wonder how long it will take before it's regulated to death "for our own safety." Big ol' knobby tires might make roll-on landings more interesting as hovering takes a LOT of gas. "Honey?? All the other guys have one..."

How about this for a punishment:
The Federal Government, by continuing to accept bids by a monopoly for it's software and OS requirement, is also giving the message that it's okay to be a monopoly. There is no incentive to change if you are still getting millions of dollars from the very Government you are supposedly getting punished by.
Here's my suggestion, no Federal contract for fiscal year 00 or 01 may include a Microsoft product. Six months, a year, whatever. That would send a definite message about the Fed's views of a monopoly.

Check again. RealPlayer 7 is out in "beta" for Linux and I've been having a ball seeing all the RealMedia stuff that I've not been able to view before.
Let's see, a post about a pre-release purchasing of a movie, I suggest that due to the current law suits going on that I might be a bit reluctant to purchase said movie, and someone moderates me as 'Offtopic'? Is that the same person who moderates Natilie Portman getting hot grits down her petrified pants up to 3? Oh well, said my $.02 HerrGlock
