Fair enough on all points. As to inductive Vs. Crosstalk, the latter is getting signal bleed in system the former would be getting signal from the old magnetic ballast the install guy ran the cable near and other similar building nasties.
My general thought train was that a faulty connection will result in 1 to 0 loss, but not 0 to 1. The latter indicates way excessive jitter or shorting (or sick crosstalk). The former may be as simple as a cracked solder joint that needs to be re-flowed. -nB
Avast is not free. They give home users a free copy as advertising. SOHO technically should pay (though I don't think the police it) and business must pay according to the license agreement.
That said I use Avast and plan on using it at my pipe-dream cyber cafe. It's a good product and fortunately they are a company that "gets it" that the home user market is rife with piracy and really is low (profit(/(work to extract $$) ratio. They aviod the issue by giving it away to home users and charging businesses, which is the way it should be with everything IMHO. -nB
Well I'll tell ya what. If you promise to pay for shipping on _all_ the audio cards I dig up I'll sell them and the manuals to you at $1.00/Lb as that's the going rate for high gold content boards.:-) I just need the space and have had that techie epiphany that I'm not likely to use the lions share of what I have and even if I could use it I likely don't know I have it so would buy a replacement anyway. The chances that I *need* that one obscure bit are rather low, and the few super rare things I have are already tucked away safely.
Most of the rest will be used to fill USPS flat rate boxes as grab bags and sold for $1-10 dollars or sold as scrap for $0.10-$1.00 per pound. -nB
This may be somewhat scary, but I recently (last year or so) gave up figuring "no-one would ever want these" and off went almost 100 of them to the gold reclaimers! That said if you really wanted one I may have one lying around somewhere. I'm going to be clearing out a 15x20x10 foot locker soon that is almost floor to ceiling with old crap. If I find any old soundcards I'll look for what the topic poster wants too....
no there's nothing "worse" except that the possibility of *creating* signal is indicative of severe issues with CM noise and inductive issues.
Going from a 1 to a zero in single ended signaling is as simple as signal loss. going from a 0 to a 1 means signal was injected into your system (again assuming positive logic).
A crappy cable will introduce jitter. Look at a data "eye" on a scope with infinite persistence on, the broader the spread at the crossing point the higher the jitter. Cable impacts this more than almost anything else. Bad jitter will cause frame sync errors and such. You should never see a 1 become a 0, and heaven help you if a 0 becomes a 1! (assumes true logic)
If I had enough money to make an impact, I'd definitely contribute to an effort to produce a competitive OS to Windows and MacOS. Um, $10 is enough to be an impact. You send the money along with a short note that says: Thanks for your work, I'm broke but I can afford at least this. It will let the dev know you care, and supply him with caffeine for a day. In addition if we all did this for our favorite distros and apps these devs would be well paid! -nB
The only time I implemented that draconian a policy it was for the gateway from an R&D lab to the outside world. I allowed access to equipment vendor sites (tek.com for example) and that was it. If you needed anything else go do it in your office, not my lab. To lock down a general office environment that much is going too far IMHO. We use an automated log auditing tool. Even one or two porn hits won't cause issues (it happens by accident sometimes).
I clicked a link in google once (before firefox and during the pop-up heyday). Blew open at least a dozen porn windows before I could hit the power button (every time you closed a window a dozen more would seem to open). Called out IT dept and they said: no worries. it flags number of hits over time, so one burst like that every few months won't do anything. The same number of hits spread over a few hours would pop the alarm though. -nB

Semiconductor R&D You want design validation. You'll be spending some time in a cube, but in my experience, you'll spend most of your time in a lab.

I think there are some dimmable CFLs but they dim by changing the duty cycle of the light, adding flicker, and are not compatible with resistive dimmers (which save no power over always on, as the excess power is simply expelled as heat).
As to LED, since you seem to use quite a few, have you noticed any issues of light intensity over distance (inverse square law)? I.e. that LED flashlight sucks for illumination in the far field much worse than a comparably "bright" Maglight. Do the fixtures exhibit similar behavior?
I have a few "always-on" lights I'd like to replace. -nB
CFL is direct radiation? Last I checked they were UV which through the use of a phosphor produced the desired color of light. Is that not indirect? -nB
I think you're being beaten up here because while an individual or even a small team at microsoft can write brilliant code, it seems without fail that the whole (vista, xp, whatever) is much less than the sum of its parts. Your management is seen as lacking direction, grasping at eye-candy and restrictive releases (re: DRM). I was going to just chalk you off as a poor shill then I read this:
I'll cut to the chase. I work for Microsoft. But it wasn't always that way. My first Linux distro was TAMU, and I first used kernel.98. My first unix experience was in middle school. I still have the sparcstation 10 i bought in highschool (Before I owned a Car, even). So, I may be a Microsoft sellout, but don't accuse me of making an uninformed decision:) so you're either a brilliant shill, or a good coder trapped at the slow moving mega-sloth. Go to Apple or Google and you will make a difference, stay where you are and I fear that you will not be happy.
I work in the hardware side of the world, and your company's main product gives me fits. I have no malice towards you, but I really wish all the zealots in the Linux/OSS cam would get their heads out of their individual distro's asses and produce a real competitor to your OS/Office suite. I think they are close with Ubuntu, now all we nead is a 100% compatible exchange server mimic and client, along with a powerpoint clone that's not power-bloat and we're all set. -nB
FWIW, manhole covers are round (and lipped) such that the cover can not fall down the hole. There spoiled that question for whomever's interviews going forward.
Also FWIW I have *no* idea where I learned that tidbit but sure as shit it wasn't college. I still don't have anything on paper over a HS diploma, been in the high tech industry doing pre-production design validation on hardware for the last 7 years. I love my job and I know plenty others who want it. A degree is worthless over real-world experience. I got in on merits and overall knowledge (recruited from a small electronics surplusser). All you need is a passion for what you do and drive to do it. When asked how I thought to implement a suite of perl scripts to compile a boatload of data (a process that took at least a week using assorted hacked together excel macros and manual copy paste) in about half an hour, I replied: I'm lazy. Why waste time on such a trivial task when the machine can do it better and I can go take more data (which is vastly more fun). Bastard promoted me for that... -nB
The interface is also fairly irrelevent when you are running a single application fullscreen. These aren't desktops. And what happens when your radar toggles to window mode, but the display doesn't scale so you lost a chunk of display. Especially if you don't have a mouse and keyboard, but rather have a console with only the keys you need for the application? -nB
