"so then i tried ..."

If you're just starting out, or even if you're a seasoned professional, why did you violate the first fundamental rule of troubleshooting: Stop, Drop, and Roll ?

If you've violated that first rule, you may very well be exacerbating the problem rather than ameliorating it. There are a lot of things you might do when an error or bug comes up. Many of them make the problem worse. For example, maybe you've deleted all your Word documents by mistake, but before calling in any expert help, you tried reinstalling Word, and then running a disk defrag. Neither of those will help recover the deleted files, and between them they will probably scramble the disk to the extent that no Undelete program in the world will been able to recover anything. There might be a chance if the system is left alone.

Users like this are like a mongoose backed into a corner: with its back to the wall and seeing certain death staring it in the face, it attacks frantically, because doing something has to be better than doing nothing. This is not well adapted to the type of problems computers produce. Instead of being a mongoose, be an antelope. When an antelope is confronted with something unexpected or frightening, it freezes. It stays absolutely still and tries not to attract any attention, while it stops and thinks and works out the best thing to do. (If antelopes had a technical support line, it would be telephoning it at this point.) Then, once it has decided what the safest thing to do is, it does it.

When something goes wrong, follow the first law of troubleshooting! Immediately stop doing anything. Don't touch any buttons at all. Look at the screen and notice everything out of the ordinary, and remember it or write it down. Then perhaps start cautiously pressing "OK" or "Cancel", whichever seems safest. Try to develop a reflex reaction - if a computer does anything unexpected, freeze. If you manage to get out of the problem, whether by closing down the affected program or by rebooting the computer, a good thing to do is to try to make it happen again. Programmers like problems that they can reproduce more than once. Happy programmers fix bugs faster and more efficiently.

"i think the tachyon modulation must be wrongly polarised"

It isn't only non-programmers who produce bad bug reports. Some of the worst bug reports ever written come from programmers, and even from good programmers. Take the example of the programmer who kept finding bugs in his own code and trying to fix them. Every so often he'd hit a bug he couldn't solve, and he'd ask a colleague over to help. "What's gone wrong?" they ask. He replies by stating his current opinion of what needed to be fixed.

This worked fine if his current opinion was right - it meant he'd already done half the work and together the problem could be solved. It's efficient and useful. But quite often he was wrong. Work could go on for some time trying to figure out why some particular part of the program was producing incorrect data, and eventually the discovery is made that it wasn't, that the investigating was in a perfectly good piece of code, and that the actual problem was somewhere else. There's wasted time.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.

anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
Hello
