...to keep running): nohup node server.js & There's also the jobs command to see an indexed list of those backgrounded processes. And you can kill a backgrounded process by running kill %1 or kill %2 with the number being the index of the process. Powerful solution (allows you to reconnect to ...

...se not that this doesn’t escape the string itself, but wraps it using \Q and \E. This may lead to unexpected results, for example Pattern.quote("*.wav").replaceAll("*",".*") will result in \Q.*.wav\E and not .*\.wav, as you might expect. – Matthias Ronge Jan ...

I have been reading the programming guide for CUDA and OpenCL, and I cannot figure out what a bank conflict is. They just sort of dive into how to solve the problem without elaborating on the subject itself. Can anybody help me understand it? I have no preference if the help is in the context of CUD...

...st is defined simply by '(1 2 3 4 5) . Python's lists, [1, 2, 3, 4, 5] , and tuples, (1, 2, 3, 4, 5) , are not, in fact, linked lists, and linked lists have some nice properties such as constant-time concatenation, and being able to reference separate parts of them. Make them immutable and they a...

I often hear the terms 'statically linked' and 'dynamically linked', often in reference to code written in C , C++ or C# . What are they, what exactly are they talking about, and what are they linking? ...

...ator protocol, which basically means they provide two methods: __iter__() and __next__(). The __iter__ returns the iterator object and is implicitly called at the start of loops. The __next__() method returns the next value and is implicitly called at each loop increment. This method raises a...

... if we define dx=x2-x1 and dy=y2-y1, then the normals are (-dy, dx) and (dy, -dx). Note that no division is required, and so you're not risking dividing by zero. share ...
