That's actually not true. I'm typing this from a Win8 tablet that gets 10+ hours out of a 30Wh battery... not shoddy by any means.

Of course, if you're running an i5 with active cooling in your tablet a la Surface Pro, you'll see significantly lower battery life. The HP tablets are likely to have very low power parts though.

People who know what they're doing use standby or at least hibernate. The rest boot... seriously, 90% of the people I know with Windows 8 laptops praise them for their fast boot times, because even with XP and 7 they used to perform a full boot every time they wanted to use their device. Years of conditioning ("Windows only runs properly when it's freshly rebooted!"), I suppose :(


Astrophysicists Use Apollo Seismic Array To Hunt For Gravitational Waves 25

This array sent back data until 1977, when NASA switched it off. Now astrophysicists are using this lunar seismic data in the hunt for gravitational waves. The idea is that gravitational waves must squeeze and stretch the Moon as they pass by and that at certain resonant frequencies, this could trigger the kind of seismic groans that the array ought to have picked up. However, the data shows no evidence of activity at the relevant frequencies.

That's important because it has allowed astronomers to put the strongest limits yet on the strength of gravitational waves in this part of the universe. Earlier this year, the same team used a similar approach with terrestrial seismic data to strengthen the existing limits by 9 orders of magnitude. The lunar data betters this by yet another order of magnitude because there is no noise from sources such as oceans, the atmosphere and plate tectonics. The work shows that good science on gravitational waves can be done without spending the hundreds of millions of dollars for bespoke gravitational wave detectors, such as LIGO, which have yet to find any evidence of the waves either.

The interesting thing is that I seem to have conditioned myself to only be good at videogames (I play mostly Counter-Strike GO these days) when I've had a sip of beer - not even a lot of beers, just one or two over the course of a few hours of gaming. I can't hit anything when I haven't cracked open a beer, but as soon as I take that first sip, the headshots start coming.

I'm actually sliding down in the ranks slowly because I've been too lazy to buy beer lately...

What kind of a workload are you looking at on the go? For office/web/coding, there are many laptops already available that will last longer than your typical smartphone.

I have a Thinkpad X220 (Sandy Bridge) that I unplug in the morning, use on battery all day (9 cell 94Wh) and then plug in when I get home, usually with 20-30% remaining after an active runtime of roughly 10 hours. A 13" MacBook Air should be able to improve on that time...

Also (according to the professor who taught my advanced mathematics course), FORTRAN compilers are easy to trick into doing exactly what you want in Assembly. In languages like C, it's apparently much more difficult to predict what the compiler will end up spitting out, but in FORTRAN they are (or were - my prof's experiences with FORTRAN date back to the 80s) able to pretty much able to optimize the actual Assembly quite well without actually needing to touch Assembly...

I found that tidbit quite interesting...
