Scientists Detect Two Dozen Computers Trying To Sabotage Tor Privacy Network
"... almost two dozen computers that were actively...", "Two of the 25 servers... ".
Oh, they clear that up nicely - "Almost two dozen" is actually 25. Perhaps dozen is like gallon: different sizes in different countries.
NASA's Next Frontier: Growing Plants On the Moon
The "coffee can" is a US unit unknown to the rest of the world. We buy our coffee in packets or jars (of differing sizes). How big is a coffee can?
Captain Cyborg Is Back! Kevin Warwick Predicts the Future
If the good captain is back in the public eye, it probably means he had a new book to promote.
Using Truth Serum To Confirm Insanity
"This certainly raises legal questions on how this is being played out 5th, 14th amendments."
How about a little less of the colloquial and a little more grammar?
The author could look "infer" up in the dictionary while he's at it.
Team Aims To Build Robot Toddler In Nine Months
WTF does a spider on tank tracks look like? I suspect it would be less creepy than a robot toddler.
Instagram Wants To Sell Users' Photos Without Notice
at what point is enough, enough.
It is like boiling a frog -- if the water gets hotter slowly enough, some frogs won't notice they are being cooked to death.
Gas Prices Jump; California Hardest Hit
Here in the UK, petrol (gasoline) is the equivalent of about $8.30 a gallon. We buy in litres these days and I only realised we are paying > six quid a UK gallon when I did the conversion to post here.
Teardown Finds iPhone 5 Costs Apple About the Same As Did 4S
"Bill of materials" does not mean what the article seems to think. "Bill of materials" is a list of the stuff needed to make something, not the cost of the stuff on the list. http://en.wikipedia.org/wiki/Bill_of_materials
Ask Slashdot: Teaching Chemistry To Home-Schooled Kids?
OP here. There have been some useful replies to my post, particularly the recommendations of books and on-line resources. Thanks to everyone who posted these. I have already followed up on several and have arranged to spend time with the kids regularly doing science experiments. I plan to focus on explosions, smoke and bad smells which, I think, are the things to keep kids interested. Once they've seen an explosion etc, I hope they will also listen to an explanation of what caused it.
I'll respond to some of the things that have been said here to clarify what is going on:
1) The boy's parents are hippies, not religious. He seems unusually bright to me, but I am obviously biased.
2) There are a lot of home schooled kids in the area and several well-attended support groups. These groups are mostly social, not educational. This area has perhaps the highest population of "alternative" types in the UK.
3) None my grandchildren are forced to learn anything they don't want to. Forcing children to study stuff they can't stand is, IMO, abusive and a waste of everyone's time. My eldest grandchild is 12. She took to reading suddenly a couple of years ago and now reads at a very good adult level. When kids (or adults for that matter) want to learn something, they do it quickly. The eldest grandchild has decided for herself to attend high school to prepare for national exams.
4) At school, I did well in all sciences except chemistry. I don't believe I lacked aptitude, I believe if you wanted to put kids off the subject, you couldn't have done a much better job than the sadistic, boring teacher we had. That was about 45 years ago. Have things have improved? Or just changed?
Passwords Are the Weakest Link In Online Security
I recommend using KeePass on Windows and KeePassX on Linux. I carry my passwords around on a USB stick. I use a password I can remember to access the password database. That wouldn't be too hard to crack, but first the cracker would need to steal the physical stick. KeePass generates nice long unmemorable strings of random characters, so attack without stealing the stick is tough.
One word of warning: one oafishly implemented site I registered with silently truncated the 20 character password I pasted from KeePass to 12 characters.
Best Tool For Remembering Passwords?
As already noted, KeePass is great for Windows. There is also KeePassX for Linux which uses the same file format, so you can move the password database around easily if you use both operating systems.
