by expatriot (#48720883) Attached to: Ask Slashdot: Are Progressive Glasses a Mistake For Computer Users?

I have two pairs of progressive glasses: one for distance and reading (obvious compromise if reading a lot) and another for computer and book distance (no good for away from desk).

Works well, but I find the transition (?) from one pair to another sometimes a bit distracting. If for example I put on the distance ones and immediately get up from the desk.

The best overall solution (optically) was astigmatism corrected contacts (not progressive) and two different strengths of reading glasses, but it was too much hassle putting in the contacts and then putting on and taking off the glasses to read anything.

Technical writing is probably the best bet unless you are both very ambitious (to spend many many hours teaching yourself) and lucky (to get past HR).

One problem with technical writing is that, like management, it is usually a one-way street. If someone who is very technical leaves engineering it is almost impossible to get back into doing real engineering because the world moves on.

The exceptions, if you call it that, are that less technical generalists can sometimes thrive in project management or marketing.

Pipelining increases performance and instructions per cycle, but at the cost of power efficiency as branches cause a pipeline flush.

The problem is balancing area, performance, and performance.

There are obviously limits the the ability to make smaller circuits, even the ones described as 14nm are not really 14 in the same way 160 was 160. There is a lot of wasted space because of the LELE process and the need to minimise crosstalk and distortion.

The real limit however is not how much better X-ray exposure will shrink the size, but how much it costs to make circuits, 28nm is likely to be the most cost efficient size for some time to come. Many fabs are making chips in larger process sizes for fast turnaround and cheap masks.

Some theories for the end of the universe say that if the expansion of the universe keeps accelerating, eventually the expansion even between subatomic particles will be greater than the speed of light and everything will be ripped apart. This is long long after the skies are black because all objects and space have moved too far away.

This is one of those topics that attracts loonies like flies to honey. Of course in the comments below, each side thinks the other side crazy too much control or too irresponsible.

For me, I think everyone should be vaccinated for common and dangerous diseases. The uncommon ones you can chose to or not (as when traveling). People don't remember polio and smallpox or brain-damage caused by measles.

“I would not hurt you, little man,' he said.

'I think that I got the disorder in Mullingar,' I explained. I knew that I had gained his confidence and that the danger of violence was now passed. He then did something which took me by surprise. He pulled up his own ragged trouser and showed me his own left leg. It was smooth, shapely and fairly fat but it was made of wood also.

'That is a funny coincidence,' I said. I now perceived the reason for his sudden change of attitude.

'You are a sweet man,' he responded, 'and I would not lay a finger on your personality. I am the captain of all the one-legged men in the country. I knew them all up to now except one—your own self—and that one is now also my friend into the same bargain. If any man looks at you sideways, I will rip his belly.'
