datr··on Show HN: Horcrux, a Mac app to back up or move your IMAP emails
This is similar to a product I've been thinking about recently. Is there anything I can use to take emails from a server I trust (my company server say) encrypt them and move them to a server I don't necessarily trust (gmail for instance) and have the emails decrypt with the standard gnupg extensions that are available for most email clients?
datr··on Genetic algorithms, Mona Lisa and JavaScript + Canvas
Indeed, I ran the script for 12 minutes and managed 37511 mutations which came up with this:

datr··on Computational reproducibility: IPython in the age of data-driven journalism
Documentation generator templates which split the comments and the code help with the scope problem of solution 1. E.g.:

http://reload.github.io/phing-drupal-template/

The trade off being that the vertical spacing of the code is now inconsistent.

datr··on Facial Recognition Failed in Boston Bombing
I've wanted to ask about this since seeing the Boston police channel available on the internet. In the UK all the channels are encrypted making it virtually impossible for a civilian to listen in. Is it simply financial reasons that the USA doesn't do this?
datr··on Idea HN: Bomb proof bins
Unfortunately I don't think there's an easy component x which you could test for.

How about weight though? I imagine most bombs are considerably heavier than normal refuse. Could we add scales to bins and notify authorities that it should be examined if the weight suddenly increases by 2+ standard deviations, say.

I suppose this could be worked around by dropping explosive material piecemeal into the bin so this would have to be paired with an effective surveillance system to pick up on this behaviour.

datr··on FBI wants real-time Gmail, Dropbox spying power
This would probably be considered fruit of the poisonous tree so would also be inadmissible. Whether the defence could show that to be the case though is another matter.
datr··on Dots - Modularize your dotfiles
Fresh is quite similar too.

datr··on Amazing Dice: Rediscovering surprise
A UK investment firm called Gloucester Research used these for a cool recruitment puzzle:

> You've probably come here via the dice we handed out at one of our recruiting

> events. By now you've hopefully noticed what's special about the 4 dice you're

> looking at: "red beats green beats blue beats white beats red", each with 66.7%

> probability. They are known as Efron's dice, and you can find some more info on

> this Wikipedia page.

> Your mission, should you choose to accept it, is to generalise the situation.

> For example, can you improve on the 66.7%? What if the dice are replaced by

> arbitrary random variables? What is the best "mutual beating probability" if

>you have only three dice? Or more than four?

It's a fun challenge and I'd recommend giving it a go if you have an interest in maths.

datr··on Ask HN: What do you use to store your bookmarks
I generally don't rely that much on bookmarks any more. I find I can recall enough about a page that a few minutes searching on google is enough to find it again. So these sorts of mildly interesting pages don't get bookmarked.

Pages that I think might be useful for some task and that I'm unlikely to recall get placed into a comment on that task in trello. Overtime each task builds up a small online literature review.

Pages that fall somewhere in between get bookmarked but if they haven't made their way to trello by the time I next wipe my computer, they're gone.

datr··on Show HN: now.sh
For an alternative way of accomplishing the example given take a look at multitail [1]. Hitting return will insert a line with the current date and time to the file you're tailing.

It also colour codes the output and allows you to tail multiple files simultaneously.

datr··on Firefox introduces PDF viewer
I really like Chrome and use it when developing just for webkit inspector but I can't switch to it for regular browsing as I still feel like Chrome can't match the browsing experience of FF. For example:

Tab Management

In firefox I can much more easily have dozens of tags without them all becoming squished. Instead I get scroll bars and a drop down menu.

With tab mix plus, tabs which I haven't read yet are highlighted.

I also have a close tabs to the left option in the context menu (which I really love).

Adverts

Adblock in firefox seems to be much more stable than the chrome alternative and just does a better job generally of blocking adverts. (This one might be solved by the likes of privoxy but then I lose the tight integration with the browser.)

Password Management

I'm a regular user of last pass but in chrome it can't integrate with the http auth dialog which means I'm forced to open up my vault and copy and paste my credential manually which is a huge hassle.

I really like Chrome and I'd love to use it all the time but these things (and a few others) prevent me from doing so. Does anyone know if there are any chrome extensions which address these issues?

datr··on Chinese Army Unit Is Seen as Tied to Hacking Against U.S.
Didn't stuxnet spread itself to air gaped machines through USB sticks?
datr··on Ask HN: What is the most impressive thing "other than this startup" you've done?
I flooded part of the University of Cambridge.

datr··on Relax. You'll be more productive
> A friend also suggested to me that it's possible for groups of people to become 'addicted' to stress; it would be interesting to see more on this.

This NY Times article was posted here a few months back and touches on the same idea: http://opinionator.blogs.nytimes.com/2012/06/30/the-busy-tra...

datr··on Ask HN: Did you regret getting a CS degree?
The danger with this is that it requires a lot of self-control to dedicate yourself to something else for three years. It becomes very easy to ignore your university work in favour for that which you're more passionate about. The risk is you end up in more or less the same position but with a lower GPA.
datr··on Can This Man Save Pinball?
Where in London? I'd love to give it a go.
datr··on Ask HN: Best way to programtically convert html -- pdf
wkhtmltopdf (http://code.google.com/p/wkhtmltopdf/) is a cool little project which uses the webkit rendering engine to generate the pdf.
datr··on 2012 Personal Annual Report
Any reason behind the move to Starbucks as the end of the year?
datr··on Fermat Theorem Puzzle
Solution: Look at the equation modulo 10.
datr··on Pen and Paper
A trick that Neil Gaiman mentioned, and I quite like, is to alternate your ink colour each day. That way you can quickly see how much progress you've made.
datr··on Show HN: I think I re-imagined IRC on mobile devices
Can you indicate how this would be different to ZNC with message replay and push notifications?
datr··on Ask HN: How do you find out what you want to do?
On a related note I saw a link posted about a year ago to a "guide to life-type pdf that was written by the CEO of an investment fund. The book had some good points in it, if anyone could share the link again I'd appreciate it.

datr··on Lego Finds Discontinued Set For Boy Who Saved Up For 2 Years
I think there was a piece on hacker news attacking them a few months back for a shift in their advertising from being relatively gender balanced in the 80s to being very boyish today.

Other than that though I completely agree with you. They seem like a great company.

datr··on That'll Never Work
The first thing I thought of when reading the title of this post is Adaptive Optics (http://en.wikipedia.org/wiki/Adaptive_optics). When I was told the idea of using a mirror which could reposition itself thousands of times a second to correct for atmospheric disturbances I had an initial gut reaction of "this will never work". There just seemed like there was too much which could go wrong or would have to be compensated for. Of course I was completely wrong - the technology works brilliantly and along side telescopes is now being used in microscopes, medicine and weapons!
datr··on Destroying drug cartels, the mathematical way
I read an article about using IBM's Watson to do such a thing about a year ago but I can't seem to find it right now. The gist was much like Watson can be used to find how data and information moved in e-discovery, the same principles could be used to determine which employees were driving innovation and had the most influence in the company.
datr··on Ask HN: Freelancer? Seeking freelancer? (November 2012)
I really like this idea. I use some of my free time to help out charities with development but I'm not much of a designer so this looks like it could be a great help!
datr··on Facebook party invite sparks riot in Haren, Netherlands
Not always the case. The clean up efforts after the london riots last year were quite successful.

This photo [1] is from during the riots but helped to restore my faith in people too.

datr··on Innocent man jailed for 8 months after DNA match
I imagine it depends on the lab. A friend worked as an assistant at a place that did forensic dna matching five years ago and she definitely used your suggested method.
datr··on Heading Out on Your Own: 31 Life Skills in 31 Days
I liked the section titled "Good manners are not stiff, formal, or awkward." It reminded me of a story I was told of a dinner party at which one of the guests suffered from cerebral palsy. The host seeing that the guest was having trouble with her knife and fork immediately put down her own cutlery and started eating with her hands. Once the guest noticed this she felt she had leave to do the same. The story's a good example of "people over process".
