Remember last February the Martian rovers were sidelined by a computer crash. The reputed problem was the huge flash memory appeared to fill due to not properly building the free inode list in the Unix OS. This was the realtime VxWorks UNIX from Charles River used by NASA on space probes for 20 years. The Spirit rover went into a perpetual reboot cycle for a day (rebooting its default response to a severe crash). Then it took two weeks to diagnose, repair and test the software patch.
So the point is, that bugs can appear even in highly tested OSes.
(3) I'd consider laser printing, introduced shortly after the Mac.

I wonder if there isa physical limit to how much potential energy of a landslide could be converted into wave height? Meteor impact students suggest much of that energy would be immediately converted into heat because the bedrock can only transmit so much energy before vaporizing.
However, as we've seen from historical tsunamis, the known largest waves of a100 feet is sufficient to kill millions.
Recently, the much of the dust was observed to have been removed from the solar panels. Wind is suspected, but not seen. This combined with approaching Martian summer bodes well for battery recharging. There were plans to have rovers "sleep-recharge" every other day or every two of three days, but that isnt needed yet.
The MERS had an original operational budget of three months, with two six-month renewals until March 2005. At some point the 2007 and 2009 lander preparations will intrude. NASA cut budgets for Magellan-Venus and Jupiter-Galileo before they completely wore out, but 3-5 times longer than their original design lifetimes.
The pathfinder only went about 110 yards over its two month career. The two Russian Lunakhods lasted just under a year in the harsher lunar climatea and went about 11 km each. The Russians had the advantage of a nuclear power source and semi-interactive remote control (3 second round trip delay).
California Governor Leland Stanford employed Eadweard Muybridge to settle a bet whether a horse gallopss with all four feet off the ground. Muybridge took the first motion picture by chaining 16 cameras together. The horse farm of this experiment is tucked away in a corner of the Stanford college campus which was founded ten years later.
The length of a day fluctuates
two milliseconds, or a thousand times more, over the course of a year. Most of this attributed to the annual pattern of ocean storms.
The length-of-day (LOD) fluctuates about 2.5 milliseconds during the course of the year. Almost all of the change is attributed to momentum of oceanic storms which change location on a seasonal basis. A quake may cause a minor step change in the baseline. Decade-long trends are attributed to rock flow in the mantle caused by glacial melting rebound and convention cells. The LOD number is an immortant geophysical monitor number.
Though the "improved" Gregorian calendar with less frequent leap years was invented in 1582, it wasnt adopted by America (England) until 1752 and by Russia until the revolution. Thats why you see footnotes on US founding fathers birthdays, with some birthdays under the older Julian calendar.
This contributed to the protestant-catholic wars of the era.
Many Parkinsons-like tremors (dyskensias) are caused by certain chemicals like insecticides and PCP. Others are side-effects of SSRIs such as Prozac. Watch out, you are playing with "Mother Nature" here. Many such side-effects arent detected in clinical trials with only thousands of participants, but until millions use it, as with recent pain drugs.
Irronically, there has been clinically measured anti-correlation between caffine, nicotine and Parkinsons. Its not clear whether these slow down progression, or whether people who have a Parkinsons-resistant brain are attracted to these stimulants.
I'd presume that short video and audio clips would help teach language. That would make a more vivid impression than audio alone. I figured I learned a fair amount of English from TV as an infant (though not as fast as the Splash mermaid).
I submitted the the idea of the space scientists/adventurer to Time Magazine for its Man of the Year. This would note efforts of both the Rover/Cassini teams and Space Ship One. I cant think of a comparable political, international or cultural achievement. Perhaps they'll give to Karl Rove who managed to keep a shakey president in office when they announce it Sunday.
The thing I remember most about the Harvard Widner main library is floors upon floors, walls upon walls of bookshelves. Some areas smelled like no one had been there in a century. Lots of stories of ghosts, perpetual students living there into old age, and lusty encounters between patrons. This atmosphere was captured in the movies Love Story and The Paper Chase. Other old, large libraries have these stacks too. where will the romance be when all this is turned into "bits"?

Since year 2000 Dynamic RAM has stayed around $100-$200 a gigabyte, while flash has fallen from nearly a $1000 to $70 a gigabyte. If you dont need RAM's greater speed, you might as well go wiht the slower and less power-hungry flash.
I dont know whats slowing down the release of next generation RAM. Typically they release a new four-times-larger chip every 3-4 years. Some RAM manufacturers have been fined recently for memory price collusion.
The Russians have a six-seater in production.
The Chinese have leased the Soyuz design for their manned space program. Early remarks point to adding more functionality than capacity. It would be usefule if they installed ISS ports on their models.

40 GB IPOD is 6.2 ounces.
Inversely, the weight per bit (ignoring checkbits and formatting waste) is half a nano-gram.
I choose IPOD as a reference because it is "a full media device" and not just a raw disk.
One five pound, 500-page ream of typewriter paper prints 2 megabytes both sides a 2,000 bytes per page of text. A gigabyte is 2.5 tonnes. Each bit is about a half milligram.
I wonder about all those teenagers holding those EF generators next to their brains several thousand hours a year. Older studies were inconclusive, but much of the world's population uses these now.
This is on a related topic. I wrote to Time Magazine suggesting that the space scientist be Man of the Year. This is due to the impressive success of the Mars and Saturn probes, and the first private astronauts.

I live in Denver and was hoping to have some beachfront property sometime. Its depressing to have to drive so far to see the ocean.

(No really. Dictionary-based natural language generation has been one of the least productive approaches int he past 60 years.)
I guess you wont have to worry about noise, extremely toxic rocket fuels, and things falling onto your house and children.
