What is the runtime performance cost of a Docker container?
...on-CPU hardware); there's significant overhead around memory paging... but raw floating-point? I'd want to look at what was actually going on there -- perhaps excessive context switches.

What is the difference between Cloud, Grid and Cluster? [closed]
...t, except that nowadays the concept is applied more widely. (I.e. not just raw computing, also entire services, or storage ...)
Grid: a grid is simply many computers which together might solve a given problem/crunch data. The fundamental difference between a grid and a cluster is that in a grid eac...
Move an array element from one array position to another
...example, this was [1]. So we take the first index of that array to get the raw 1 there.
Then we use splice to insert this element in the new_index's place. Since we padded the array above if new_index > arr.length, it will probably appear in the right place, unless they've done something strange ...
What are allowed characters in cookies?
...e going by the Netscape spec or RFC 6265, whitespace is not permitted in a raw (un-DQUOTEd) cookie value. It does nonetheless work in browsers I've tried, but I wouldn't rely on it.

Which C++ idioms are deprecated in C++11?
...lly deduced would help a lot making the syntax more easily comparable to a raw loop.
Basically, reading algorithms made with standard algorithms are far easier as words hiding the implementation details of the loops.
I'm guessing only higher level algorithms have to be thought about now that we ha...
Multiple arguments vs. options object
...the last three are optional.
So why not do this? (Note: This is fairly raw Javascript. Normally I'd use a default hash and update it with the options passed in by using Object.extend or JQuery.extend or similar..)
function map(nodeList, callback, options) {
options = options || {};
var t...
Rolling or sliding window iterator?
...ables and small windows. On larger windows, the deque pulls ahead again in raw speed.
Access to individual items in the deque may be faster or slower than with lists or tuples. (Items near the beginning are faster, or items near the end if you use a negative index.) I put a sum(w) in the body of my...
Microsoft Excel mangles Diacritics in .csv files?
...ion where they don't particularly support Excel < 2007, but are sending raw UTF8 text to Excel, which is misinterpreting it and sprinkling your text with à and other similar Windows-1252 characters. Adding the UTF8 BOM is probably your best and quickest fix.

Fast way to get image dimensions (not filesize)
...know how much room it must reserve before starting to read the file. Some "raw" type file formats might just be a stream of bytes with some "end of line" byte at the end of each horizontal row of pixels (in which case the software must read the first line and divide the size of the byte stream by th...
What is the difference between buffer and cache memory in Linux?
...er caches. Since 2.4, the page and buffer cache are unified and Buffers is raw disk blocks not represented in the page cache—i.e., not file data. The Buffers metric is thus of minimal importance. On most systems, Buffers is often only tens of megabytes.
