DATA: All shield, weapons, and propulsion systems are offline. We are being drawn into the nearby star Jhi-Quwo IIV. Hull temperature is reaching maximum tolerances. I estimate destructive hull breach and core detonation in 23 minutes...22:59...22:58...
PICARD: Geordi! Is there anything we can do?
GEORDI: Well, Captain, there is one possibility...but there may be risks.
PICARD: We're in a risky situation now! What is it?
GEORDI: I've run some analysis and we may be able to slingshot around the star and get to a safe distance -- if we can survive that long. Currently we will be unable to withstand the heliosphere of that star. But there is a chance...
PICARD: Yes?
GEORDI: One of the crew members has a vapor-phase cooling system installed on their workstation. If we can utilize a tachyon pulse modulator in combination with the vapor-phase cooler and route it through the warp core and to the shield arrays, we just might have a chance...
PICARD: Make it so! Who has this vapor-phase cooling system?
GEORDI: Well, sir, uh, *cough*worf*cough*
PICARD: What? Worf?
WORF: Grrrr...(string of Klingon insults and scowling) 0v3rc1o|<3rz r00l!!11!
PICARD: *head in hands* I guess this is it. Send a message to Starfleet, and tell Dr. Crusher to meet me in my ready room.
Sorry, this really annoys me: It's "preventive," not "preventative." Don't say "orientated" either, it's "oriented."
Please.

An Athlon with a different chipset. And do research first this time; you'll find Intel chipsets with problems too.
Also if you want reliability, hunting for the "budget replacement" is probably going to hurt you. Probably part of the reason this current computer isn't working. I've had friends whose Asus boards died pretty quick.
Well...with some creative engineering, maybe it could get up to that speed.;-) It would certainly bounce over the terrain nicely. Maybe more of a hamster-ball type of concept with internal wheels driving the ball.
Look up to my second post on this thread, I have a link to a more traditional concept I rendered last night. For scale, the wheels are supposed to be ATV wheels.
Whatever it is, it needs to be bulky enough not to get stuck in a foot-wide gully. Maybe something with sets of tri-star wheels, and a very wide wheelbase to keep from tipping over. I whipped together a rendering in POV-Ray, which explains the concept for those who don't know what "tri-star" means: robotconcept.jpg (121.95 Kb)
Ideally, the robot should be able to keep going if it does get tipped over. That was the beauty of the sphere concept...but of course, the atmosphere on Mars is pretty thin and winds wouldn't have as much of an effect.
The robot ideally needs to be able to navigate without fear of being stuck on a 2" pebble 100' from the starting line. Obviously you can't map 250 miles of terrain down to millimeter resolution, but you can design the robot to render such obstacles nonexistant.
One concept is a large inflated sphere with light tread patches on the outside. The power/electronics pack is suspended inside with cables running to various points on the sphere. By adjusting the lengths of the cables, the sphere can shift the center of gravity and roll forward. A 6 to 10 foot sphere would allow most small obstacles to be avoided, then the robot only needs to note current position and the general surrounding topography.
Major difficulties with this concept are high winds (unless they are blowing in the right direction!) and steep uphill gradients.
As a petroleum product, though, I'd seriously doubt that it would be as inert.
There's additives and things in there, too; I could see solvent components getting into bad places. So what exactly is required to dissolve the adhesives holding a layered motherboard together?
USB and Firewire are vastly different from EIA-232 and siblings.
USB is much closer to Ethernet than it is to EIA-232. I've done some serial development and some USB development, and the USB development is abstracted from hardware by several layers; while serial is barely abstracted by one layer (in microcontrollers, if you're lucky to get a UART).
It really is different. I would agree that students would benefit from learning more modern interfaces later on, though EIA-232 is perfect for teaching basic communications concepts. I certainly had difficulty the first time I developed a USB peripheral; it had never been taught, if barely mentioned at all.
It makes sense now. The abstraction almost makes it easier to develop for on the PC side, and there are amazing features built right into the protocol. A simple microcontroller can change from a keyboard, to a mouse, to a joystick, or dozens of other devices with a simple change in firmware.
They're not practical for any purpose other than being a wedding ring, and do you honestly need any more purpose? If I ever have need of one, I'm definitely going with the sine wave style.
Dan Statman (of the site you linked) is a member of the TurboCNC community, CNC software that runs on an old 486 with step rates up to 20,000Hz. TurboCNC is being actively developed by Dave Kowalczyk. It's 100% free to use, $20 for the Pascal source. This is for something that can cost hundreds or thousands of dollars elsewhere, and would never run on anything below 400MHz.
Dan Statman built all of his own tools, using TurboCNC to drive his titanium-ring engraver. He quit his job and does this full-time now. He's a regular poster (as am I) in the TurboCNC user group.
It's amazing what you can do with $300 of scrap metal and surplus parts.
I would recommend 'the Pragmatic Programmer' by Andy Hunt and Dave Thomas over this book.
Such a multi-talented man Dave was. I still prefer Wendy's over any other fast-food restaurant. So the 'Pragmatic Programmer' has an extra-spicy approach to coding?
I guess you're trying to make a point, but at least post under your own name. People might think it was me complaining about the mods. No big deal, I wasn't trying to rack up my karma (can't any more anyway).
The next goverment-sponsored RTS will be awesome. Pay 500,000 gold for a peasant, 30.6 million for a ballista.
I'd pay good money for an updated version of Lemmings, in which the characters are models of current government officials, patchable after every election. "Oh, sorry, the bridge to the 21st century is taking a little too long to build. Haha...*splat*"

If don't mind, I join your shuddering, since you said...that...that word.
I could not resist.
You meant to say "for all intents and purposes" instead of "for all intensive purposes."
Sorry. Just trying to squash the stereotype that we all can't write or spell.
If I'm not mistaken, vapor-phase cooling is just an ordinary refrigeration cycle.
Geeks, of course, always go for the term that would sound coolest on the bridge of the Enterprise.

Try it with an 4-wheeler ATV and we'll watch for you. Maybe dump a GPS and primitive steering arrangement on there for a better chance.

Incredible. Thanks for the link!
Yay for comments that are better than the story!
I once saw an old article detailing how you could build a circuit to attach to your radio, and then attach it to your oscilloscope to see the image.
It's called Slow-scan TV, and has been around for ages.
No.

I see we've come full-circle back to X10.
...around Christmas, the vendors brought in a massive plate of cheddar and crackers, and an equally massive plate of fresh jumbo shrimp cocktail.
;-)
;-)
That's what you get for being loyal to your vendors.
Also there was the time I figured out that rollerblade wheels were a good replacement for something we were having custom manufactured.
Load up Movable Type and blog those volunteers into submission!
Also, this site may be helpful. Someone has already done a LOT of research and typing.

Not superior, but definitely not wasting my valuable time while being programmed into impulse buying.
currently have 5 computers setup in my room, but should drop to 3/2 soon
1 and 1/2?
Poor, poor half-a-computer! What are you going to do, remove its floppy drive? It will have no reason to live!
