The linked page says "High level != inefficient" and shows an example program which will print "every TCP packet". With no "if" anywhere in the code, I wondered how it knew to print only TCP packets and not oth

So you use a GC and have occasional CPU usage spikes. You correctly identify the cause. You then use "unsafe" code to go behind the GC's back and build some stuff which probably has crash bugs or worse, and by your analysis

Major ones include R, Python, Matlab, and K/Q, roughly in that order of current popularity. Matlab used to have more marketshare and Python less.

Don't you see the connection? School fees are high partly because people can get free money to pay them. This of course screws the people who do not take the free money by defaulting on loans.

All automated trading technology providers suffer this paradox: failing customers will fail, excellent ones will profit and move on to develop their own platforms. It's unavoidable. You must continually attract new customers and hope s

With the status quo, say you call malloc() once. After a long while you call free(). Now the first thing free() needs to do is figure out the size, which is stored "before" the pointer. Until that load is complete, it can'

Having used both SWIG and Boost.Python professionally, I find manual work required by the latter to be 100% worthwhile and usually necessary. C++ and Python are not very similar, and the result of auto-binding them typically gives up a comb

Really interesting writeup. The contraption has parallels to some of what we do with software: automating a legacy system without completely reinventing it. For such an accomplished practitioner, the author made one glaring mistake: > W

That won't help. Concatenate needs to know the total length up front. It will evaluate all the input items at once.

I live in Singapore and even within the past years there has been a clear shift in cuisine as hawker centres become homogenized. Long ago the street vendors were shifted into groups under permanent roofs. But over time the areas under those

You could make a single-state work permit without internal borders. If workers from California want to spend their vacation money in Nevada, let them. You can still reject them if they apply for work in another state.

Why does the Economist republish its own articles on a different subdomain with a current dateline? This one is dated 27 March, but it has a link right at the bottom to the original, from 5 September 2013: http://www.economist.co

I read your post and am left with two questions. 1. Robinhood Gold interest is 6%. Interactive Brokers is 2.4% [1]. Why do you think there is such a massive difference, and would anyone benefit from paying it? 2. Your analysis works on ten

Sailing is a very stereotypical rich man's sport, and track & field is perfect for the poor (low equipment and facilities costs). So it's no surprise the research used these. But they are saddled with a confounding factor: par

I don't see why that would help. Of course there is more precision in terms of decimal places around 1 than around 360. But if you use 360 each 1 represents a much smaller piece of the circle. To put it another way...it's about si
