At the opposite end of the spectrum, you can buy some very expensive tools that let you try to capture every single nuance of the software in the UML diagram itself, and the code is generated directory from the UML model. Yes where I work a couple of million dollars of developer resources were burned up doing this. The pure OO code it generated just wasn't appropriate to our application.
Hauer completely blows away Ford in that movie. I have read that the speech he gives before dying came from Hauer, but was discussed with Scott in advance. It wasn't in the original script.
By the time the lander gets to about 30 meters (98 feet) above the surface, it will have slowed
to about 2.4 meters per second (5.4 miles per hour) in vertical velocity. Continuous adjust-
ments to the thruster firings based on radar sensing will also have minimized horizontal veloc-
ity and rocking. Touchdown will be about 12 seconds away. For that final piece of the journey,
Phoenix will maintain a steady descent velocity with accelerometers until it reaches the surface
for a soft touchdown. It will shut off the thrusters when sensors on the footpads detect contact with the ground.
I don't even think that would have worked very well on Pluto. There is obviously a limit to how cold something can be, and thermal conductivity being what it is (not having access to real world thermal superconductors, sorry about talking about that other book) it would take hours to freeze solid on the surface of pluto and probably days to get down to a few degrees kelvin.
Nice story all the same. What I want is a way to grow circuits through my brain, following the existing logical structure so that I can eventually dump that biological substrate. Hey! that might be a new approach to transhumanism.
Once you've achieved genesis however, evolution takes over, and so long as you don't have a fast severe change in conditions, life will adapt over time to become well-suited to whatever the environment can throw at it. This is why I think martian life would be obvious to us if it existed. The fact that we have to hunt around for it strongly suggests to me that it doesn't exist.
Two billion years from now it may be difficult to imagine life evolving on the Earth. If you can still find the Earth, that is. Time has a way of hiding things. OT but in Harry Harrisons Stainless Steel Rat books people from 30000 years in the future are puzzled as to why the name of the ancestral home planet of humanity translates as "Dirt".
LEDs are solid-state, but are presently very expensive as lightbulbs. In outlay, yes. But they are unlikely ever to need to be replaced. I could imagine light fittings being sold with hard wired LEDs, and lasting decades.
Add anything that is not "politically correct", and it'll be filtered.
1. Encryption is mandatory over such a network
At 25 Mhz with a bandwidth of, what? 1 Mhz throughput will be 1 megabit per second shared with hundreds of users. Free wifi in the gigahertz range is already a joke. This system won't have the throughput for (decent) porn, encrypted or not.
I have an eeePC and I reckon a version without screen or keyboard would fit into a box (say) 100*100*20 mm. It would be great for taking to work on my bike.
Why the hell is the department of justice hosting a manual on how to be a terrorist? So they can arrest the people who access it? Sounds like something which could be automated to a high degree.
My wife is an architect. She has just started using CAD (Autodesk Revit). We were at the shop yesterday looking for a new windows box for her to use but she fell in love with an iMAC which was on display.
I can get more RAM for the MAC, and parallels, but is it likely to be practical to run Revit on parallels? I know that it would be hopeless on vmware. She needs mouse interaction to be perfect.
I am just looking for an indication of how fast windows runs in parallels.
As an industry, we really need to start growing up and using the tools the mathematicians have provided us, just as other engineers do in other disciplines, to show our programs actually work as advertised.
The competent have nothing to fear from formal verification and anyone who is not capable of doing such verification should not be writing software anyway.
How can I keep unvalidatable requirements out of my system? In my field, validation is used to show that the software satisfies requirements, not that the requirements are in any way correct.
Still, the OS kernel is, by definition, one of the most complex pieces of software in a system. Only because of its architecture. I know of many more complex systems but they are modularised into different processes with middleware for interfacing.
My laptop is low on ram (256 MB) and it stops responding under load all the time. The reason seems to be disk saturation caused by firefox, but that shouldn't make it not be able to scroll windows.
I run netbsd on some systems and have noticed that performance degrades much more gracefully than linux.

So ruby has gone off the rails?
It is generally thought to be impossible to make a movie which could do it justice.
Bits of it have been ripped off by so many mediocre films that it might be accused of being derivative, which would be tragic.
You were wrong Case. To live here is to live, there is no difference.
Strange that they got so much dirt on the pads then. From the Phoenix landing press kit[pdf]:

Good point.

I am surprised this one is so large.
Solar power should be required by the design standards for commercial air conditioning systems.
Taking out an albatross could be bad luck.
Looking for a bit of advice.

You can google for it. I found this document.
