Two words: Angular Momentum
At the outside of the disk there would be an incredible amount of stress on the rotating media. The head seek times would go up as well.... Though, while 7200+ RPM would certainly be out, and likely 5400 RPM as well (remember the old drives ran <= 3600RPM, I would consider a 4200 RPM 10 TB drive for near-line storage... even 5.25/FH that would be a decent volumetric density (equivelent to 5x 3.5" drives). -nB
no I meant 100C. Mind that the boards are off, and remember that while in reflow the temperature is vastly over 100C. The whole point of being at that temperature is to boil the water. metal migration does not occur in Si semiconductors until well over 125C.
We use CMOS grade IPA (95% Rubbing alcohol) to clean boards all the time. Works a treat.
Buy a couple gallons from a chem supply company and a handful of *hogs hair* brushes (not metal brushes, obviously, and not nylon, not so obviously)
If you can't order from a supply company, then you will spend more, but get either 99% IPA or 190 proof everclear from the drugstore and soft bristle toothbrushes. Go to town, be sure to lightly soak the board under components to flush out residual water.
Bake cleaned boards under some 60-100 watt desk lights for a day or two (close enough to feel that the boards get warm) or in your oven at 110deg C for about 90 minutes (door open). -nB
I work on firmware and one of our biggest challenges is that there are soooo many seperate systems that have to come together that even though the devs unit test their code to death (and for the most part it works), once you start integrating stuff, things break. You have the kernal, then apps running on it, then the end user interface software. All this simply must work. The only way to get there is to test it. 5000 hours of tests, and yet we still had escapes:( As to the submitter: Ask how you can get involved with writing software to help your group. Even if it's "programming" a smarter excel sheet to collect data, or a perl parser with GD to plot results automatically from logfiles, just find an unfilled itch in your group and scratch it. If it's hardware QA, see if you can work on programming your instrumentation drivers/data collection/etc. While I genuinely realize what I'm going to say is not true everywhere, many bosses are open to employee development, especially if it helps their group out. Tell your boss you'd like to grow your skills and want to stay in the group. Ask where you could pick up a small extra project. Be proactive and *look* proactive. Most managers want smart employees, just not smart asses. Single most important advice: be humble. A close second? Don;t piss in anyone's cornflakes/eat from their ricebowl (especially if they are territorial).
this all assumes your injectors are electronic. My car uses a Bosch IDI mechanical pump so while if the throttle is off the fuel load is small, it still injects fuel consistent with the engine RPMs. FWIW.
actually, we have the opposite way of doing things. you may only use "My Documents" to store business docs, no other dirs of your filesystem. A daily backup job runs (and we are encouraged to do a manual run if we feel it's needed). Backups are journaling (and de-duplicated). Works a treat and limits data loss on average to 1.5-2 days of work.
Just to be clear here... [mic check]123 alpha bravo charlie[/mic check] you appear to be advocating for violent overthrow of the United States Government. Is that correct sir?
FWIW I'm writing a full test suite for our hardware in perl. kind of like e-test, but while I do timing centric and low level stuff in C, I'm writing the test scripts in perl. It's actually the right tool for the job as anyone can modify the script as needed for their boards and if you know c/c++ then there is very little you need to know additional to modify an existing perl script. We are nearly a 100% windows shop too. (there are a few people with MACs (mostly running windows) and we do test most of the major OS's on our boards at one point or another, but the bulk of the testing and software is Windows based. -nB
simply using zips would obfuscate this, yes, since compression works by removing redundancy (thus increasing entropy).
As to backups out of date, All you need is the previous backup and the current encrypted volume. Since most people do not back up after every file change, there is your required delta.
There are three easy solutions: *backup to a separate encrypted volume with unique encryption keys. *use entropy increasers in your encrypted volume (zip, rar, etc.) *don't backup your encrypted volumes.
yes, but here at least, an unpatched rogue XP install will get you a writeup of the unpleasant sort. I too have a dual boot system, XP for IT centric stuff, Linux, when I don't want IM, Mail, IT crap etc. My boss know and loves it (had to let him in on it else he'd wonder why I'm always off-line.) -nB

The 32 bit limitation is 4 gigs of RAM (total). Your video card's memory is mapped into the same address space as your system ram, but from the top of the address space downward, rather than system ram (mapped from bottom of address space upward). The video ram has priority, thus if you have 3G of ram and a 1G video card you are using 100% of your address space. any more system memory installed will be masked by the video ram and thus is "lost". -nB
Ok I'm going completely OT for the most part here. as to your first points AFAIK all accurate. As your comment about the sig, true as far as it goes with it's assumptions, now on to the OT part: you are looking at garden variety images, then you come across one as in the sig you commented on... What now. If you are repulsed, close the browser, etc. then what? Is it still a crime (thought or otherwise?)
Problem with our legal system is the answer is yes. A single questionable image is enough to fry you, even if that was not your thing and the viewing was accidental.
It's ok. My front plate is stolen regularly... It is a hassle, I have to go to the DMV and order replacements then show up at the city office to get a sign off of my fix-it ticket once the plate is installed. Then it gets stolen again. (go figure):) -nB
Intel knew they were losing the performance curve long before AMD passed them. Woodcrest was the response, yes. It's development started in parallel with attempts at making netburst faster (as a mitigating strategy IIRC b/c while netburst was built for speed, their R&D dept was having trouble getting said speed from Si transistors) and when they came out with it, it was after quite some time in R&D. Remember, the architecture of the CPU is one part of the equation, and also IIRC Woodcrest uses a lot of the previous proc's arch, built with a new transistor and some other front-end tweaks to lower power. It wasn't a radical design change, it was a radical implementation change (cheaper and faster than wholesale re-design). -nB
I hate to burst your bubble, But neither company is "decades" ahead. Both are roughly 4-5 years ahead on transistor design, less so on architecture. Based on what I do know of business, if they were decades ahead on a product they would get it to market ASAP, not sit on it.
Any time you see a tech company "sitting" on something for a trade show, it's because they are still trying to get it to work as close to flawlessly as possible, not because they are hoarding technology.
Ah, you made two fatal mistakes (possibly three) 1) you did not wait till your karma was 'invincible' only 'excellent' to start a flame fest 2) you did not do what most trolls do and create a trash account for this flame fest 3) you did something that I can't seem to put my finger on while I wait for my build script to finish... (going on a 16 hour day here)
Actually I happen to think you're smarter than you think I think you may think you are. (or something along those lines) but for some reason these 'mod points' you people are referring to are foreign to me.;-)
