Absolutely spot on.

I wrote a Calcudoku generator/solver a while ago (now in heavy use at http://www.calcudoku.org/ and spent a _lot_ of effort on the difficulty rating bits (and still know there is room for improvement).

One idea that isn't in there yet is to somehow incorporate the distance between the solving steps: if the next logical step is in a cell very near the previous one, you see it more quickly, hence the puzzle is easier.

Comment: do what you love (Score 1) 379

I'm an older programmer (yes past 40, programming for about 30 years) and find no problems at all with finding work.

You'll bring more experience than the hipsters. Only issue with some companies is the higher rate/salary.

Ridiculous that once you're older you should be managing a group of 20-something programmers: do what you love, and if that's programming and not managing, stick with it.

Obscene and Tasteless - This category will block sites that offer advice on how to commit illegal or criminal activities, or to avoid detection.

The trick is to combine things that parents will obviously want
to block (in that category: "how to commit murder, build
bombs, " and "gruesome or even frightening content such as
shocking depictions of blood or wounds, or cruel animal
treatment.") with stuff that the MPAA/government etc. want to
block: "Sites with information about illegal manipulation of
electronic devices, hacking, fraud and illegal distribution of
software will be blocked along with ..."

... in the same category!

"Illegal manipulation of electronic devices, hacking" is nice and
broad as well, so plenty of sites to block.

Why is hacking "obscene and tasteless" anyway?

I've posted a (torrent of a) 6 month archive of tweets about bitcoin at bitcoinscope.com

To be precise, it's 50% of all tweets (every other tweet), so it can be used as a training set, with the other 50% to be used as a test set later (for your sentiment tracker / price predictor, etc.)

Following this announcement President Ortega of Nicaragua also offered asylum "if circumstances permit it". Snowden had previously applied for asylum in both countries."
