Password Security: Why the Horse Battery Staple Is Not Correct

catprog Re:Not contradictory (546 comments)

Sorry the calculation should be
10,000 * 16 * 100 * 2 * 2 = 6.4 * 10^8

Password Security: Why the Horse Battery Staple Is Not Correct

catprog Re:Not contradictory (546 comments)

XKCD's shitty advice is protecting against brute force attacks by using length (even though in many cases the effective length is still limited to something stupid like 16 characters). By following XKCD's shitty advice, you open yourself up to statistical attacks - your search space is just a combination of a few words. People generally only use a few thousand words, and when you want them to be random about it they'll likely pick common ones, fairly short ones, mostly nouns, etc.

4 words from a list of 1000 words = 10^12 possible passwords

10,000 uncommon words, 4 symbol replacements on average , 2 digits of numbers , numbers at the start or end. capital/non capital at the start.

10,000 * 16 * 2 * 2 * 2 = 1.28 * 10^7.

A lot less passwords.

Any other ways you can think of to increase the passwords complexity?

Humans are terrible at being random. Any magician, con-artist, or statistician will tell you that. The most commonly-picked "random" cards are the ace of spades and the queen of hearts, for example. The 4 "random" words scenario will give you a search space many orders of magnitude smaller than a good, traditional password.

That is why you need a randomizer to pick the words rather then you picking them.

Solar Could Lead In Power Production By 2050

catprog Re:The big problem with PV (167 comments)

I'd say you live in a warm climate.. Cloudy days means more energy in colder climates. France uses at its peak about 100 GWatts of electricity. Say you'll need at least 10 hours of battery storage, then you are talking about 1 TWh of power storage for 100% replacement by PV. .

So a peak that lasts 10 hours?

If fact the 40% peak PV is for a Sunny Sunday afternoon, so a lot further away from 80% than you think. .

So storage is even further away from being needed?

And if we go to the actual data at http://en.openei.org/apps/TCDB... and not a cached version we get a different view.

Numerous Methane Leaks Found On Atlantic Sea Floor

So I presume you are not a big fan of mammals but instead reptiles. They were the dominate species after all during that period.

FCC Warned Not To Take Actions a Republican-Led FCC Would Dislike

catprog Re:By that logic... (338 comments)

Was that the company that brought near GPS spectrum despite it being regulated for something different then what they wanted and then the FCC would not change it too what they wanted?

The Cost of Caring For Elderly Nuclear Plants Expected To Rise

catprog Re:Falling energy prices and weak demand? (249 comments)

I think I see the confusion.

Wholesale price = -2.5c + feed in tariff 3c = .5c profit.

I was calculating the feed in tariff separate from the wholesale price.

The Cost of Caring For Elderly Nuclear Plants Expected To Rise

catprog Re:Falling energy prices and weak demand? (249 comments)

if the feed in tariff is 3c . Then so long as the operator can sell power for more then -2.9c he will do so.

(possibly even -3.1 if their was a cost in shutting down)

MIT Combines Carbon Foam and Graphite Flakes For Efficient Solar Steam Generati

catprog Re:3T gallons at a Superfund site with earthquakes (110 comments)

I am not saying to use that site. It is still an active mine . I am just using it as an example of the size of the hole needed.

(you may be able to halve the number by using the amount dug out to form a upper reservoir too)

The main problem with this method is of course the cost.

And you have only flooded the US to 34m. Somehow I think the US is not 34m from it's lowest to highest.
