Comment It's not exppensive either way (Score 1) 837

"...it's next to impossible to create quality cable (ie: cable that will pass a Time Domain Reflectometer test) by hand without expensive dies, special Ethernet jacks and special cable...."

The above is 100% correct except for one work "expensive". The dies don't cost a long. You can buy th tool for under $50. None of the other stuff is expensive either.

That said, Cable with the ends already on don't cost much either. It's just that it is very hard to pull cable with the.ends on

Also look at the fire code. You can need plenum cable.

They are wide band two inch wide helical scan tapes. The specs on those tapes are very impressive even by today's standards. For example we use wide band analog tape in our lab and the specs are not much different. The machines don't cot so much any more only about as much as a new Lexus

You have to figure those old machines where not built for the lunar mission. NASA didn't have that kind of money. These were US Air force machines.

For just getting one machine to work their current method is the best. What they did was get a bunch of these old machines and disassemble them for parts to build one that works. The guy doing that is a volunteer working for free. Hard to beat zero cost.

If you wanted to build many machines then yes, re-design one from scratch. But have you priced the cost of custom one off software. I'm in that business and I'll rtell yo that $1M does not buy you much/ The only reason software is cheap is because they sell millions of copies.

Comment Use VMware or other virtual environment (Score 1) 655

If his software runs under DOS then rub a virtual "DOS" system inside a modern OS

That Modern OS can be Mac OS X, or Linuix. Or even Windows.

Once the computer is running out of a VM yu no longer have to worry about the hardware lasting. You can move copy the VM image file to a DVD or hard drive and plug it into any Mac, Linux or Windows computer that has a VM player and boot the VM image and be up and running. So your system becomes abot as "portable" as a music CD.

Buy him a few 20" iMacs and set up his software in VMware's "Fusion" and he'll be good to go. He will be able to keep up to date as new version of the OS come out while is old software runs in the VM.

Comment No, it is "carbon nuetral" (Score 1) 468

Yes CO2 is produced but the carbon in the (let's say) corn came from the atmosphere. So when it is decomposed or fermented the carbon is put back where it came from.

The burnning of fossil fuels releases carbon back into the air also. This carbon was taken out of the air also but the problem is the time periods. The cabon in oil is the result of millions of years of plant growth and then it is all burned at once in a couple centuries.

Alcohol production is closer to steady state. Same with burning trees and dry grass.

I agree with about above. You do see the small companies grabbing the guys with the best GPAs. The mid level GPA end up at the bigger places.

But WHY? Well there big companies need LOTS of people and by definition there are not a lot of high GPA students. There are simply not very many people in the 5th percentile.

Also they are looking at cost. The big guys need to keep their payroll costs in line

"What many of these HR types look at as a first criterion for consideration is your GPA."

No, they are even more lame than that. Yes they will look at GPA but not first.

The FIRST thing they do is run your resume through a "buzz word filter". They will simply count how many times you use words they are searching for.. Many times they do not even know the meaning of the words.

Then if you pass this computer filter they will rout the resume to the hiring managers based of the "fit". The managers mark some resumes are "interesting" then the HR person will look at the GPA and which school you came from, years of experiance and so on.

"can happen" and "does happen" are DIFFERENT. Yes anything CAN happen. Study CS now and then at age 55 learn to play the guitar form a rock band and be a millionaire. Could happen but likely not.

The best advice is to not thing "I'm different" because of all the people who think that way few are right.

The can't swimm upstream thing is 90% correct. A few people can beat the odds but 90% don't. Basically if you flumked out of mach in the 9th grade and never really "got" Algabra then you are likely not going into Electrical Engineering. Yes you could later go to the local comunity collage and work at math and then go back the universtiy but you get into you managment job and you have kids and don't want to give up the time to go back to school. VERY few beat the rule about swimming upstream. But enough do beat it that we hear of it. Just like some kids DID end up playing for the NBA.

Comment Re:If you are asking this question (Score 1) 372

You are right about that. I ask managment all the time for decisions about "Which is more important? Which of these two ways do you like?" I as an engineer know what I know and I'm happy to defer pollicy questions to management. Part of my job is to explain technical details so that managment CAN make decisions.

I work in the space launch business. There are a lot of smart engineers here but not ONE of them understands how the entire rocket works. I know a little about telemetry software but NOTHING about cryogenic turbo pumps. Not one of us engineers could get a rocket off the ground. It is the management process that makes it work.

I'm 100% certain the the "next big thing" maybe in 40 or 50 years will be intelligent machines. But for this to happen we will need a HUGE leap, a breakthrough in our theoretical understanding about what intelligent being are and how they work and a very deep level.

Which sounds more exciting to you. Writing performance evaluations of router installers or witting software? Only you know what you want to do.

Look at the Apple Mac Pro. It comes with ECC memory. It's not the only computer either.

Most people buy PCs based on price. If they can save $5 they will. These people don't get ECC but then they aren't doing anything critical with their computers, just games or the Internet. Anyone running a critical service would have some kind of redundant setup to either deal with the crashes or prevent/reduce them with with things like ECC, RAID, dual power supplies and so on. Sun's servers even allow you to "boot around" failed hardware

Memory testing will NOT protect from casmic rays and flipped bits, what they call "soft errors"

Comment Re:Filesystems in the kernel! (Score 1) 265

"A database management system is nothing but a fancy filesystem with structured files, yet they are often used in servers and perform just fine."

Yes that is true but "perform just fine" for a database system means something different from "perform just fine" when you are talking about a file system.

For example many people would be happy to see their DBMS do 500 table inserts per second but a file system that could to only 500 writes per second very slow.

All this talk about what should go inside the kernel is pointless now that for years we've had a modular kernel. You can configure in or out what ever you like. If you want a user space file system you can have that or not have it. It's all very configurable.

Comment Re:Adapt (Score 1) 626

You are correct. What is needed is a new instruction set. But we don't need new machine level instructions. Source code level is good enough. A programming language or API that works at a higher level is what's needed. Currently you have to get down in the details of synchronization to make threads work. What's needed s a more declarative approach where you can "mark" sections of the program with informatin about how they interact.

Object Oriented Programming is not a bad way to write parallel code. If the objects model real-world objects that each can be on it's own thread. Problem is that most dumb programmers idea of "object" is a GIU widget.

In the end it is more about educating developers.

In fact if you are buying a computer just for this purpose, Buy yhr one that has the largest maximum RAM. You want at least 4GB. Also get the best disk system you can afford.

Processor speed is not really what you need but you do want a modern Intel Core2 and loads of RAM
