The first problem of this sort that I encountered was back in the 70's on an octal machine (telephone computer). The last two digits of the year were stored in a hardware counter so on Jan 1, 1978 the date showed up as 1970 instead of 1978.
for those that might not know octal, 77 is the max value for two digits then comes 100. 8's & 9's are illegal values.
Same with me. No pager, no cell phone, no television, no newspapers. Just me and my lady living in a cabin in the forest.
The dialup line is a hassle though since the trees are too tall for a satellite connection and Sprint will not have DSL in my lifetime in this area of the Appalachians.
I would not trade working from home. I almost never go out unless it is for fun, movie, to eat or to party.
I really tried to follow the logic in your comment but while reading it, I suddenly began to feel like I was on speed or something and lost it on the last sentence.
Could you clarify your comments?
Here are my beliefs
Usually larger disk drives have cylinders that are closer together and thus the typical access time is less as the head move a smaller distance.
Also larger disk drives often have more heads/platters so more data can be accessed without repositioning the heads.
Quite often the data is packed more tightly on larger capacity disk drives permitting more sectors of data without repositioning the heads.
The increase of RPMs only affects the latency of the information being accessed.
my friend, Why not ask for what is good for those on slashdot rather than what is good for your karma.
I personally support displaying a short page like this rather than waiting long hours for the site to become operational again after a slashdotting experience.
Actually, I find myself often lining up on the other side of the ACLU on most issues.
Most ACLU confrontations seem silly and wasteful rather than focused on those that really are in need of help.
This case, however I do support and would like to see the DMCA dismantled piece by piece.
I spent a long time in china back in 1980. The Chinese government was worried when the chinese peasants were getting the money (yuans) that the China vistors were spending. (at that time we were to buy only at the authorized places) however there was a lot of black market and gray market stuff going on.
So the entire money system was exchanged for a new style of money making the old money worthless. So the chinese individuals who accumulated these old yuans could not trade them in for the new currency.
The exchange of the old money for the new was really well organized though and caught many peasants unprepared.
Being skilled in hardware and software plus knowing the kernal that we used at the time kept me hopping between the cities.
Had to take a train to Harbin though as the planes can't fly that close to Siberia during cold weather.
I found the people there to be extremely nice and caring about my comfort more than their own.
Like I said "perhaps a bolted one for those who want to tinker or experiment."
I was not trying to make a top to bottom comparison, rather that disk drives have greatly improved in MTBF over the years and I see cars following a similiar path.
Perhaps it is anedotal and only appears to be so to me based a limited set of occurrances with which I have been involved, however I don't believe that to be the case.
I headed up the PC integration center for McDonnell Douglas (when it existed) and saw many many PC's with disk drives being built. Mr expwereince with cars are much less though.
I do concur that comparing the disk drive to the whole car is not totally adequate, however comparing the disk drive to the engine isn't either.
You are right, there is a parallel that i have already seen with disk drives.
The first disk drive (CDC) I work on had a big hydraulic actuator to move the head carriage and the whole drive was about 5 feet long, 3 feet wide and 4 feet high with a total capacity of 262K or something like that. A detent dropped into a slot on a gear to keep it on track. It required daily periodic maintenance - cleaning the heads and rollers
Then the move was to voice coil head movement and the drive got smaller and required less service, however you could trace a signal through the logic to fix it when necessary. RM05 types
Then CDC came out with an onboard computer to run the drive. All sensors and buttons were inputs to the computer and all relays and motors were outputs from the computer and what really happened depended upon the embedded microcode. Signal tracing was very difficlt and readout lights displayed the errors that accumulated similar to cars today.
The drives become more and more reliable until now a typical drive's MTBF will outlast your computer twice over not to mention the storage capacity increase.
It would be nice to see this progress with cars as well. And well, one can still fix their own hard drive if they wish, but why bother unless the data isn't backed up.
I was a teenager in the 50's and 60's and we tinkered with our cars so they would run.
Today my S-10 has 55,000 miles on it and other than periodic oil/lube maintenance all I have replaced was the serpentine belt because of a cross country trip i was taking. That is 55,000 miles without any problem at all with the pickup, and this is not uncommon.
My Mistibushi Montero has over 125,000 miles on it and except for scheduled maintenance items there has been no failures either.
We never achieved that in the 50'd or the 60's. If we got 5,000 miles without a breakdown of some kind we considered ourselves lucky.
So maybe a welded hood is not such a bad idea eventually, or perhaps a bolted one for those who want to tinker or experiment.
When I worked in OZ back in the 70's the voltage varied by locations. Somplaces it was 240V AC and other places it was as high as 270V AC.
Did they standardize the voltages?
Well, are the train tracks the same gauge now? Going into some territories they had to change the carriage wheels on the cars because the tracks were different widths
I worked with a lady named Bonnie who lived in KC. For her Anniversery, her kids saved up money to treat her and her husband to a night out. They were dancing under the skywalk when it let loose and instantly killed them both.
I had stayed in the hotel several times before and patrons did indeed make the skywalks swing. I don't care what the experts say, having that skywalk swing back and forth had to weaken the material at the points of stress.
You aren't too far wrong on removing the functionality to Chinese.
The company I worked for a couple of decades ago sold disk drives to the Chinese with high altitude heads and the RPM of the platters were reduced from 3600 RPM to 2400 RPM.
Also extra capacitors were added to the seek circuit so the settling time after a head seek was greatly extended. This was done to reduce the data access capability of the disk drives.
Several months ago this (or an exact situation like it) was an "ask slashdot" entry and many slashdotters said NOT to notify the company nor the competitor.
If I recall correctly the situation was that you lost a contract to a competitor, the competitor did a marginal job, and left the site open. It appeared to most slashdotters that your pursuing this was sour grapes in an attempt to win back the client and make your competitor look bad.
Telling the client was like telling a mother that her baby is ugly. In essense he made an ugly choice.
Over and over the advise was not to even go to the site and definitely not to notify anyone because of this very thing.
Oh what the ego can do to us. A site lost to competition is a poison site.
Even an innocent visit to a poison site may not be defendable if the site is cracked later and your addresses are found in their logs.
Life is about choice. You chose a most difficult board postion and I wish you well in the end-game.
That was the Hyatt Regency. I stayed there before the accident and when the band would play, spectators on the catwalks would start the catwalks to sway by pumping the catwalks like a swing - adding positive energy.
I lost a co-worker that night that the two cat walks fell. It was their anniversery and their kids saved their money so that their parents could celebrate by dancing, dinning, and spending the night.
Evolution is in process. The mind is being modified from a mind that works like a file cabinet... where we simply open the drawer and extract the information that we want... to a mind that "knows" the answers and works from intuition.
during this change which is occurring to all age groups, the file drawer memory is being dis-barred to a degree so that the intuitive mind can come forward and take charge.
After the intuition is functioning then the file-drawer memory will once again become acessible as it once was.
I find that many individuals with ADD's are "Indigo Children" and that they will be very God like in the forth coming years and will instruct their parents, teachers, and supervisors and will be often mistaken for the "One"... in each case he/she will carefully and lovingly correct the mis-understanding.
If you do not know about the Indigo children then search the web and after reading about them, see if you do not find that it is about most of the individuals on slashdot.

Not all nuclear wapons had such safety devices. This is before your time, but a B-52 crashed off the coast of North Carolina back in the 60's. Now at that time there were 6 switches in each warhead that had to all be closed to detonate. When they recovered the warheads after much difficlty, one of the warheads had 5 of the switches closed just from the impact of the crash. If the 6th had closed then we would have blown up a part of North Carolina.
The designers then realized that conditional situations had to be enforced and so various switches were used that could only occur in a normal delivery condition of the warhead such as what you describe.
This was at first top security information, but then this information in great detail was given to the USSR so that they too could safely keep from blowing themselves up and thinking it was us that did it.

Curt Lemay was a tough cookie. He would smoke a cigar while an airplane was being refueled and if someone would mention that the plane could blow up he would say "It wouldn't dare" and keep on smoking.
An old story about a general dying and going to heaven. As he was talking to St. Peter he exclaimed that there was Curt Lemay and how did he get to heaven. St. Peter replied... no, that's god... he just thinks he is Curt Lemay.
Lemay once walked out on a briefing by the military strategists after he ask them how did the Navy targets and the air Force targets interact. A few days later we were out at the missile silo's reprogramming the targets and re-aiming the missiles. It turned out that there was no interaction between these two departments and some targets were overly targeted by both and others were not targeted at all.
The air force was aghast that they had to co-ordinate with the navy, and the likewise for the navy.
I was in the air force during the cuban missile crisis. I was a systems analyst and my job was to aim the minuteman missiles to their target and to program in the launch information about the various target choices available.
Things like whether the target was Moscow or Paris (kidding) and whether it was an air burst (destructive) or a ground burst (dirty).
Missile sites near Malstrom AFB Montana that were still being built by Boeing were comadeered by the air force and missiles and warheads were installed even though everything was not completed within the silo.
Few portable radios were available back in the early 60's and ALL were confiscated by superiors. The only things that we knew was what we were told by our superiors. So we knew little as to what was really happening.
Only that it was imperative we got as many silos into strategic alert (green) as possible in the shortest amount of time because eveyone of them counted.
One thing is that there will always be the "have's" and the "have not's". Earth is about duality, it is about individual growth spiritually. All of the focus of it... in the final end is pure illusion. The night life is illusion, the internet is an illusion, and even JWZ himself is an illusion.
I myself am retiring from the computer industry which began in 1960. It seems that there were lots of changes, but in the final glances that I make... "nothing has really changed".
I live in Southeastern Ohio in the Appalachians. I see poverty and 8th generation welfare families who have no hope and see only despair.
I too was a millionaire on paper with Wang Labs several decades ago and when Wang fell on hard times many dedicated employees experienced what the dotcoms employees today are feeling and might yet feel.
Where JWZ chooses to focus his energy and money certainly is his business, however the scope of need of humanity is much wider than the glitz of a tinsel town or the Bay area.
JWZ is gifted with a great amount of Energy, and Stamina, and Wisdom and he is in a position to make a difference. His choice is where to make that difference.
