Re: Wearable tech lets boss track your work, rest and play
I think workplace performance should come with 'desire' to the technology. Programmers desire to code and code and see it working. Software testers like to find mistakes and prove it not working. Bug fixers desire is to fix bugs create the best patch and keep the #fixes that he fixed. Hardware troub...

Re: Increase disk Space in Windows 7
How large is your C: drive?. Mine is 37GB, but only about 3GB left. Most of the space is wasted in windows folder due to WinSxS folder (5GB) . I wish I could delete that folder. :evil: As much as Google seem to think everyone has fiber optics links connecting their homes to global network, Microsof...

Re: Chemical weapons sniffed quickly by zappy detector
When their hatch is open nuclear weapons on ground could be identified using satellites in low earth orbit.
When will be able to identify chemical weapons from the satellite ?
I'm waiting for that new future day.

Re: refrigerator power saving
Is this what you talking about ? http://upload.wikimedia.org/wikipedia/commons/thumb/e/e4/Condensatorenbatterij.jpg/800px-Condensatorenbatterij.jpg If so this does not help. This is designed for applications beyond 10KVA. You could never cover your ROI in 10 years if you only using a fridge. But if ...

Re: How to validate HTML5 forms without JavaScript
Somewhere I've read that it's not good to use attributes in HTML5. So is there any way to do the same thing without using attributes but only css ? Just to know. One another question, According to how I feel , I think validation belongs to the behavior of the page. So then it should belongs to HTML ...

Re: MQ7 & MQ135 Gas Sensors
If your application is automobil then you need oxygen sensor too. Because parameters would change due to oxygen concentration.So this question is all about sensor calibration right ? so it's sensitivity graph. And please note that it's x and y axes are on logarithmic scale. So sounds like the the si...

Re: Copying files over Wi-Fi
So this is about 4 Mbits/s which is slow as you said.Having 3 out of 5 signal bars in not too good, so that could be the issue. Having low signal strength is associated with the low bandwidth you have. Is the net drive that you copy local or in the internet ? If it is local, then I do see an issue....

Re: How to switch on/off 4 bulbs individually and together
Well, I reviewed your design sir neo. Sounds no problem since LS1-3 are pure resistive loads. And yes 240V 4 pole dual throw relays are available in pettah , and yes the brand name OMRON. But how could that item is just only 150/- Rs while it's in here around 1800/- Rs. So I don't think it's origina...
