My wife is into going to estate sales. There's even a phone app that she looks at that shows where they are with pictures of what's in the sale. So last Saturday we found an estate sale that was in the neighborhood and we went. In the dusty basement there was some old computer accessories and I saw this little blue thing with a data cable attached and I said I bet this is a Zip drive. Sure enough. My first thought was I don't think you can buy the data cartridges for it any more. My second thought was I wonder if anyone under 30 knows what a Zip drive is. The folks running the sale had already had a trash dumpster out front of the house.
EDIT: I guess the valve stem could be the shaft inside the coils of the solenoid. Another point is valve springs have incredibly high force constants - they are really hard to push. This might take a pretty high current to open the valve.
I assume the electric valve system would use something like a solenoid to push against the valve stem supported by a spring. The solenoid would need a force exceeding the force of the spring to open the valve.
I'm not an expert here, so please correct me if I'm wrong. One thing about solenoids is that they are either on or off or at least the times to actually activate the push on the valve to full open or release its force for full close are pretty short. Cam shafts are shaped for a more controlled valve action. I would guess that one could control the current through the solenoid coils to match that of the cam action. All this would mean computer activity, control circuits and a substantial increase in electric energy use. Also, there needs to be a serious comparison for failure modes between the two systems for reliability purposes. There are some common failure points such as a broken valve spring, but replacement failure points such as the failure due to solenoid piston valve stem contact wear in stead of wear due to contact with the cam or failure due to timing belt breakage instead of the electrical control system failure. And if failure modes are equally probable, what will be the respective repair and maintenance costs? I'm not sure which will come out to be the better solution.
Just what I was thinking. Take a baby (babies?) that's a total orphan and have it grow up as if it were born on Mars, then send the adult to to Mars. After all, the new Martian will not be returning back to earth ever.
The picture in the original NASA article to me shows arrangements like some chemical structures including perhaps fused rings. There is a nice hexagonal ring in the middle of the pic, much like a benzene ring, with some substitution. Do we have some kind of spontaneous formation of low energy structures here? All this is really neat.
This film may have gotten it right. Haven't read the short story ("The Sentinel") or book, but assume those opening scenes in the film were represented in the short story by Clarke. Apparently the book of the same title was written concurrently with the film's production and released after the film's release. For the film, the screenplay was co-written by Kubrick and Clarke.
Yes, that's right. They're really useful only with a display and my guess is the display will be something from Apple made in China or maybe, if the interface is right, in Korea.
Made or assembled? For instance, where did the display panels come from? I'm not sure any LED/OLED or whatever panels are made in the US. Spinning hard drives could very well be manufactured in Thailand. Keyboards? Who knows. The same thing goes for cars and trucks. Notice the tag on new vehicles will indicate something like North American content with a percentage. Mexico is a North American country and many such vehicles get their engines from there.
This is what I was wondering: before the big bang, and whatever it was that resulted in the big bang, was there time and was there space? Space and time were created at the instance of the big bang and before the big bang (ah, that thing in our reference system, time) neither space nor time existed. Furthermore, is space and time still being created outside the volume of the universe? If quantum mechanics posits that a particle of matter can transition from one place to another while being at both places simultaneously, does space and time exist where this transition occurs? Again, this use of space and time in our reference system vocabulary...
"Microsoft updates support policy: New CPUs will require Windows 10"
And here's the summary,
"In a change to its longstanding support policy, Microsoft says PCs based on new CPU architectures, including Intel's Skylake chips, will require Windows 10. A list of preferred systems will support older Windows versions on new hardware, but only for 18 months."
It says,...new CPU architectures, including Intel's Skylake chips will require Windows 10.
The article doesn't say that in 18 months new CPUs "can't" run other OSs. But also it doesn't say new CPU's "can" run non-Windows 10 OSs. Tech journalists are journalists, after all. Read any newspapers lately? I'd expect more from Ed Bott, though.
Intel hardware to become windows-locked so you won't be able to run any alternative OS.
I don't think windows will run on UltraSparc and I doubt it runs well on Arm.
There have been headlines for some articles that implied that the latest Intel processors would only run Windows 10. My first thought was Apple might have to build Windows 10 machines or get a different company to make its processors.
If this proposal goes into affect wait 'till you see the continuous robocalls and other "advertising" and non advertising spam on your cell phones voice calls. It will be continuous and not just 10 per day and you won't be able to keep up with it. What is happening to land lines will happen to cell phones.
I can't find my copy for the exact name. It was published, I think, by the HAM radio organization. Incredibly useful for both the amateur and professional. Not sure if it's been updated for the digital world. That tells you how old my copy must be as well as me and my need to use it.
The problem with back doors is that they can lie in the software for long periods of time while data theft continues unknown to its owner. Stealing a physical key, stealing a pickup (and sending it to Syria) or car will likely be noticed quickly. And of course, there may be multiple back doors, so swatting down one of them doesn't ensure data security.
As many writers in these forums have noted, once a back door is installed, anyone, good or bad, with the appropriate tools and skill can open the door. The distinction between bad and good guys seems to be blurred these days.
Exactly! Then again, how would you prove you played a lottery and lost? People won't keep a lottery ticket if it didn't win or the cash register receipt for the ticket purchase. The individual states might sue but that wouldn't help those who paid and lost.
Clearly everyone along the "chain of command" need to know math, including the legislature writing the law, the governor who signs and orders it implementation of the law, and the many likely members of the prison hierarchy who will interpret the rules that go to the ultimate coder. My guess is there is no equation in any of these communications and it's not likely that there is much, if any, reverse communication back up the chain.
Chemists have also found The Merck Index, Beilstein (Beilstein's Handbook of Organic Chemistry, founded in 1881), as well as Chemical Abstracts (CAS) published by The American Chemical Society to be incredibly useful and necessary. All are either available on the Internet or other computer databases. Before computer accessibility, a year's subscription of CAS in paper would occupy something like a yard or more of bookshelf.
I'm sure other professions have their necessary references they could not do without.
Perhaps theoretical mathematicians see what I see as pretty simple concepts of arithmetic as higher math. OK, I can go with that but on the practical level maybe not so much. One of you stated the math involved here is high school math. I think I learned that the result of 3 times 4 is the same as 4 times 3 or the result of 3 + 4 is the same as 4 +3 in elementary school. One should obviously know that the result of 4x(3 +1) is also the same as 4x3 + 4x1 but not the same as 4x3 + 1 which may be the mistake made by the prison officials.
In talking to a HS math teacher he pointed out that much of his first year HS algebra course is 5th grade arithmetic since his students' math experience was at that level coming out of middle school. No wonder one-third of HS grads need remedial work when they get to college.
Those who write software, even if it's a spreadsheet calculation, sometimes need to understand the distributive and commutative rules of arithmetic. Actual knowledge of the names of these terms doesn't excuse one for understanding the principles of arithmetic. No higher math needed.
i think there's a difference between the number of jobs and number of job openings. The original article asserts that the number of EE workers will remain constant for the next 10 years. If that's so and some workers vacate their job positions as EEs either by retirement or for other reasons, then there will be some opportunities for EE graduates. Where they come from is another question.
What we need are the data as to the number of new hires that will be needed to keep that worker number constant. It would also be useful to know the number of new US EE college grads expected during the next 10 years. Will supply exceed or be less than demand? Predictions like this are sometimes unreliable, but the IEEE should have some guesses at least for the next four or so years given college enrollment in EE programs and some knowledge of the EE economy.
This is totally different. The linked article even explains it
Following the link, it tells us that model aircraft to which the rule applies are defined as "unmanned aircraft... Flown within line of sight".
As i understood it, the new FAA rule applies to drones capable of being flown outside the pilot's line of sight. Therefore this law is irrelevant as to whether or not the FAA can regulate, since it covers a different type of aircraft.
I have no idea what the turnover rate is for EEs. Some fraction of those in the profession will retire, die or otherwise leave the profession leaving room for new graduates in these fields even if its population is constant. And of course if the age distribution is such that an increasing number are nearing retirement age during the next 10 years the opportunities for new grads will increase. The original article doesn't say anything about that.

We used to use it as lawn fertilizer in Michigan from a product called Milorganite produced buy the Milwaukee sewer system.
