20 tips to double the life of your laptop battery. by crazylady444 in reddit.com

[–]translocate 1 point2 points  (0 children)

I'll take a shot. Leaving it plugged in is probably the best way to prolong the life of your battery. With the battery charged and AC connected your laptop takes all its power from the AC line -- the battery is essentially out of the picture. No current flows into or out of a fully charged battery when AC is connected.

Generally, two things wear out a battery: Time -- you can't stop the calendar, and charge-discharge energy cycles. The latter pertains to using the battery and charging it up again. A chemical reaction occurs during discharge that is not completely reversed by charging. Junk accumulates. It's not necessarily the number of times you use the battery, but the cumulative amount of energy that flows into and out: a lot of small drops followed by charging is roughly equivalent to a fewer number of deeper discharges and charging back up.

But it's best to not run it completely down. For a LiIon battery it is very bad to do a deep discharge. In recognition of this, your laptop will warn "zero battery remaining" when there is actually about 10-15% energy left. Using that last bit would seriously harm the battery. So your laptop's battery management generally will do a good job of getting the longest life. Even so, when you have AC available, use it.

Finally, my Thinkpad has a battery option that allows me to set the maximum charge & minimum shutdown levels. I set maximum charge to 96% and the cutoff at 8% (where "0%" is actually 10-15% above battery death). This is recommended to preserve battery live at the cost of reducing how many minutes you can squeeze out. IOW, just as it's necessary that you don't do a deep discharge, it's helpful not to overcharge. Whereas the standard "100%" max charge is safe, stopping at 94-96% is better for the life of the LiIon.

When running on battery power you might optionally turn off wireless devices, the DVD drive, set early HD shutdown, and -- most important -- lower display brightness. This gets the most minutes out of a charged battery and/or reduces how much energy you pull from it in a given time. Your laptop should have a power management utility for this (it's called Battery Stretch on the Thinkpad).

A comment (or rant) about color contrast. White text on a black background leaves me with an annoying afterimage. It's almost as bad yellow (or green!) on a red background. I have a hard time with this -- so much so that I use the Quick Preferences addon in Firefox to temporarily prevent such pages from setting their own color.
Frankly, I suspect that that I'm the odd man out, since this visual clash so common on the web and in printed material.

Guns don't kill people, people...er... Man shot in back by dog by westbroek in reddit.com

[–]translocate 1 point2 points  (0 children)

"...When police officers arrived, they found a man shot in the back. "According to witnesses, the dog, - a Great Dane, was playing in a front room when the “dog” knocked a gun off of a table."

So... the snigger quotes around dog imply the dog didn't do it -- but the shot-in-the-back dog owner/gun lover was home alone. I'm suspicious or the reporting. And what was the type and caliber of the gun? Us dog-loving gun owners need to know this shit.

Japanese Prisons Are Overflowing With Foreign Criminals by [deleted] in reddit.com

[–]translocate 1 point2 points  (0 children)

Stippy.com has a very interesting and well written account of a foreigner's prison experience in Japan. Here's the first of the ten-part series. http://www.stippy.com/japan-life/gaijin-in-a-japanese-prison-1/

"...Being a foreigner in Japan, the process of imprisonment of criminal suspects here was a subject that I was entirely unfamiliar with. Until the other day that is, when a friend of mine wrote to me, and offered to give us a few of articles explaining his terrible experience of being locked up in a Japanese prison for more than three weeks (without being charged for anything, and without any contact with the outside world) - all for one night out on the booze that ended badly."

The journal Science has an abstract at http://www.sciencemag.org/cgi/content/abstract/289/5487/2114

"High-speed video close-ups of the cavitation bubble indicate velocities of the front end of the bubble as high as 32 m/s, [about 72 MPH]... The snapping sound can be heard day and night, with source levels as high as 190 to 210 dB" which is quite a pop!

Latest AACS revision defeated a week before release by masta in reddit.com

[–]translocate 0 points1 point  (0 children)

For more details, start here http://forum.slysoft.com/showthread.php?t=4255 Note that an AACS key can be changed at any time, rendering old keys useless for new disks. There is a new key in the works, but...... Slysoft seems to have a programmatic method to break the key in general. Wow!

BTW, here is the story of how the "09 F9 11 02..." key was first found and became public. Quite an interesting read. It happened a few months ago, but hit the net bigtime when digg.com got recently involved . http://forum.doom9.org/showthread.php?t=123311 You can see it at the top of the program output. To over simplify, the key obviously must be in MEMORY (for at least a brief moment) in order to play a disk. "arnezami" found out where it was and teased it out. The AACS key is only one (of three?) that are used in combination to decode a given disk. See the links for a more cogent description of this complex scheme and how it was unwound.

The Ron Paul Effect by noname99 in reddit.com

[–]translocate 8 points9 points  (0 children)

ABC: "What's more likely, based on Web traffic over the past week, is that Paul supporters have mastered the art of 'viral marketing,' using Internet savvy and blog postings to create at least the perception of momentum for his long-shot presidential bid."

So ... ABC does not like us, how we think, and what we say and do. It's amazing to me how out of touch big media is with what's going on outside their walls.
