Out of curiosity, what other computationally difficult problems are there?

I'm very interested in bioinformatics, but sadly don't know as much about the field as I'd like.

You don't seriously believe that any age restrictions are able to prevent a 14 year from seeing whatever porn he/she wants? Or whatever else.

Sure, they might make the process a bit annoying, but in the end it's always possible to simply jailbreak the device. (not to mention that most 14 year olds know more about technology than their parents)

This is great, exactly what I needed for the new Coursera class about Programming Languages: https://class.coursera.org/proglang-2012-001/class/index

(They start of with ML and a very simple REPL)

Is there a reason why all the fields for protobuf are declared as "optional", when it looks like they are in fact not optional at all?

I can't seem to clone the repo anymore - can someone push it to github?

I'm confused. Why does it matter which name you have? Why keep the old ones and not just pick a random new one you happen to like?

> Canonical's secret sauce in selling carriers on Ubuntu might lie in helping them sell their own services to end users. Carriers "care about brand and we know how to accommodate that," Shuttleworth said. "They care about their own content and we've essentially put their content on an equal footing with content from the ecosystem. The handset manufacturer or operator that has music, films, or other types of content can promote their content to their users or other users directly in a way that doesn't feel like a bolt-on or a sideshow."

I do not want any content from my phone manufacturer, much less operator. From experience, this is almost exclusively overpriced crap, useless apps or branding.

Interesting tidbit about preordering: They claim to only bill when they ship a device, but ask for Credit Card information. Ergo they need to store cc information in clear text somewhere.

Leak in 3.. 2..

If it's like the other chromebooks, you can if you enable Dev mode.

You could always have that, but now you can use just "yourdomain.com" instead of a subdomain.

I believe you are referencing "DIE WAHRHEIT, WAS WIRKLICH PASSIERTE UND WAS IN DER ZEITUNG STAND" (the truth, what really happened and what the newspapers said) http://events.ccc.de/congress/2012/Fahrplan/events/5181.en.h..., which is the talk after the keynote.

Jacob's talk was in English.

Especially since this is obviously obfuscated Haskell. A more readable version:

  pow = 1 : [ 2*x | x <- pow]

I just started to look through the slides and they look really cool. However, only on 80% zoom can I actually see the "run" button at the bottom. It would be great if you could fix this :)

iirc, if you write a kernel module you have to release it under GPL, but if it's just a user space program you can keep its source closed.

works fine for me in Chrome 23.0.1271.64 on Ubuntu 12.10

the script I use on linux:

  #!/bin/bash
  userid="your id here"
  myfile=$(date +%Y%m%d%S).png
  scrot -s "/home/mononofu/Dropbox/public/$myfile" 
  echo "http://dl.dropbox.com/u/$userid/$myfile | xclip -selection c
  notify-send "Done"

Spanner is also a kind of butterfly in German: http://de.wikipedia.org/wiki/Spanner_(Schmetterling) ;)

This reminds me of the Teensy: http://www.pjrc.com/teensy/

Anyone up for a Hacker News meetup at the congress?

As some from Metalab in Austria, I can only agree. Feel free to visit!

Club Mate is definitely an acquired taste, but it grows on you - I really like it now.

That said, you should definitely come - C3 is an amazing event, there are always great talks and sessions. If you need some help with German, just ask me ;)

the name is quite annoying, but it has a ridiculously large battery.

Now I have to decide between the Nexus 4 and the Droid Razr Maxx HD :-/

a) how is this different from browsing on your desktop?

b) why would a company as big as Google care about what a single user does?

this is why I'm going to the US, in a nutshell. Sadly, there are not a lot of options at that level here.. (aside from working in a local Google office)

Why do they assume that I'll be only testing on either laptop or desktop?

This looks like Fountain codes: http://en.wikipedia.org/wiki/Fountain_code

Basically, you split your data into blocks, XOR random blocks together and the client can recreate the data by solving the equation of which blocks where XORed with which.

A good tutorial is here: http://blog.notdot.net/2012/01/Damn-Cool-Algorithms-Fountain...

And a fast implementation: http://en.wikipedia.org/wiki/Raptor_code

At least in my university solutions to all past problems are posted anyway, we even have our own wiki for it. I imagine it's similar in other universities.

(fwiw, I use Github exactly in this way, only with public repos)

As someone taking the course - yes, it was pretty obvious. And even if he had said nothing, it's common sense that uploading other's solutions as your own is frowned upon.

I for one like the new keyboard and think it's great. (I used both old and new keyboard on two Thinkpads simultaneously for 2 months)

I've never really been able to get into Vim, but this is completely awesome! Especially on laptops, where scrolling and hitting links without a mouse is really annoying normally. (yes, I know, page up / down, but those scroll too much)
