Is MATLAB OOP slow or am I doing something wrong?
...T: I used to have some notes here on "path sensitivity" with an additional table of function call timings, where function times were affected by how the Matlab path was configured, but that appears to have been an aberration of my particular network setup at the time. The chart above reflects the ti...
What is the best CSS Framework and are they worth the effort?
...r presentation into your markup. 'div class="span-24"' is no better than a table, you'll have to go back in there and change the markup to affect the layout. And all the frameworks I've seen are based around fixed-pixel floated boxes, making it impossible to create a liquid layout accessible on a wi...
What is declarative programming? [closed]
...tion for a completely different user just executed a similar query and the table that you are joining with and that you worked so hard to avoid loading is already in memory anyway.
There is an interesting trade-off here: the machine has to work harder to figure out how to do something than it would...
Pointer to pointer clarification
... "lvalue" instead of "variable", but I feel it is more clear to describe mutable storage locations as "variables".)
So we have variables:
int i = 5, j = 6;
int *ip1 = &i, *ip2 = &j;
Variable ip1 contains a pointer. The & operator turns i into a pointer and that pointer value is assig...
JSTL in JSF2 Facelets… makes sense?

Hash collision in git
...wice. But "surprisingly few" is a very relative term here.
Wikipedia has a table on the probability of Birthday Paradox collisions. There is no entry for a 40 character hash. But an interpolation of the entries for 32 and 48 characters lands us in the range of 5*1022 git commits for a 0.1% probabil...
How useful/important is REST HATEOAS ( maturity level 3)?
...e client development schedule. Abrupt changes to the API are simply unacceptable to everyone involved, as it disrupts traffic and operations on both sides.
So, an operation like that would very likely benefit from HATEOAS, as it's easier to version, easier for older clients to migrate, easier to be...
Java 256-bit AES Password-Based Encryption
...putStream is not much of a problem. Shuffling all the exceptions under the table is a problem. The fact that the salt suddenly has become a field and that the IV is required is a problem.
