ulvund··on A Prediction: Bitcoin Is Doomed to Fail
They are infinitely divisible
ulvund··on Julia for Numerical Computation in MIT Courses
I think the idea is that you can move the threshold on when to implement in Fortran/C(++) since you only have a '1x-5x slowdown' for most common application compare to the 20x-5000x slowdown with R/Python/Matlab/..
ulvund··on This is for bicycles what Tesla is for cars
Electricity powered bicycles are not that rare here in Denmark, they look like this:

which is not particularly more heavy than your average bicycle. They are mostly used by elderly ladies and heavy-set women, so the Tesla marketing aspect is not huge.

ulvund··on Free Online Book: Bayesian Reasoning and Machine Learning
The first few chapters of

ET Jaynes: 'Probability Theory: The Logic of Science': http://bayes.wustl.edu/etj/prob/book.pdf

Are great (and free) as a thorough introduction to bayesian reasoning.

ulvund··on Bitcoinica sued for $460,000 by 'out-of-pocket' punters
That's just glib. People use lots of bitcoins on silk road every day with no interest in speculation. Bitcoins are a real currency with value backed by the interest in silk road products.

If you can only look at bitcoins from the viewpoint of turning a quick buck, then you are not able to see a substantial part of the elephant.

ulvund··on Bitcoin just crossed $7.00.
My guess is that bitcoins are mainly used for college students' and drug hobbyists' $50 purchases of LSD and the like on silk road and not for big transactions.
ulvund··on ESPN Developer Center
How far back does your score data go?
ulvund··on Julia is a high-level, high-performance dynamic programming language
If you have worked a lot with R you won't be surprised that anything is faster than R
ulvund··on Ask HN: What would you work on, if money was of no concern?
It is possible here in Denmark. There is a very safe and unique ID for everyone, the kicker is that it costs $0.60 per user/year to utilize.
ulvund··on Ask HN: What are the good old ideas that still make money on the web?
It takes a hell of a lot of $50 websites to pay an average programmer's salary
ulvund··on Tell HN: RAM Requirements are going through the roof
Exactly, OP does not understand the role RAM plays in computers.

It is a disappointment for me to see the link get so many points in this community where you would expect the baseline of knowledge of technology to be 'above the average'.

ulvund··on The Slashdot Effect from the Other Side
Static. On this site I host mostly huge-ass html files (about 1 MB per request) with apache 2 and mod_deflate :-)

There is also a wordpress site and another database-request-heavy site with 500 requests a day.

The problems I had was that the access.log and error.log quickly ate up the 5GB space of the micro instance :-) Causing mysql to stop operating and me to scratch my head for a few minutes.

5GB is not a lot .. you want ruby1.9 with the default setup? That will be 180MB, and so on :-)

ulvund··on Hypercasual: when the web gets a little too friendly
It's a small point to make but there are no cat videos on my small corner of facebook :)
ulvund··on Google Fiber: 151Mbps down / 92Mbps up
A lower bound for latency to the 'other side of the earth':

(20 000 km) / the speed of light = 66.712819 milliseconds

I have never seen this attitude
ulvund··on Google Plus Deleting Accounts En Masse: No Clear Answers
I think the main purpose would be for Google to target ads very specifically like facebook does now.

ulvund··on What G+ is really about (pst it's not social)
On Facebook you buy ads for ~$1+ because you can set target demographic to something as specfic as "women; 42-47 years old; looking for relationships with other women; with a degree in biology or computer science; attened Harvard; Works at IBM; who likes horseback riding or skiing"

Imagine if google knew BOTH your search term and your complete personal history. Then the ad price and conversion would increase enormously.

That is what Google is trying to get a piece of.

ulvund··on Light - If you view the Earth from far enough away can you observe its past?
Strictly speaking, everything we see happened in the past :)
ulvund··on ITerm2 1.0 Released
I have a hard time changing functionality of the alt key between alt and meta. I Terminal.app I just go to preferences and it is there. Here it takes a little more..
ulvund··on An example: being mentioned on Reddit

ulvund··on Team Fortress 2 now free forever
It is funny CS enabled Valve to make a ton of money eventually
ulvund··on Team Fortress 2 now free forever
Valve has Steam from which they take 30% of any game sale. So they will never hurt for cash. They can give away every game they ever make and still make a killing from selling others' games because they have the most popular and best working platform.

Valve is now in the content delivery network business and just happen to have a department that produce video games.
