Please explain some of Paul Graham's points on Lisp
...mpiler can't provide first class support for - if you make a simple syntax error, the compiler is unable to give you a clear error message.
Well, with Lisp, you have all this in one single language. You use the same stuff to generate code at run time as you learn in your first day. This isn't to su...
Why does Python print unicode characters when the default encoding is ASCII?
... with some bogus encoding:
$ export LC_CTYPE=klingon
# we should get some error message here, just ignore it.
Then start the python shell again and verify that it does indeed revert to its default ascii encoding.
$ python
>>> import sys
>>> print sys.stdout.encoding

Convert light frequency to RGB?
... observer (which could be considered to be the "precise" model), there are errors. But from the paper, if you look at the Figure 1 on page 7 (compare (d) with (f)), this method provides quite a close approximation. Especially if you look at (f), you could see that there is also a bluish line even in...
REST, HTTP DELETE and parameters
...e. Judging from your use of the DELETE method, this is not the case.
HTTP error code 409/Conflict should be used for situations where there is a conflict which prevents the RESTful service to perform the operation, but there is still a chance that the user might be able to resolve the conflict hims...
How do I choose grid and block dimensions for CUDA kernels?
... those limits, any kernel you can successfully compile will launch without error.
Performance Tuning:
This is the empirical part. The number of threads per block you choose within the hardware constraints outlined above can and does effect the performance of code running on the hardware. How each co...
Do you need to dispose of objects and set them to null?
...l = 5;
//iVal == 5
}
//iVal == 8
In C#, however you get a a compiler error:
int iVal = 8;
if(iVal == 8) {
int iVal = 5; //error CS0136: A local variable named 'iVal' cannot be declared in this scope because it would give a different meaning to 'iVal', which is already used in a 'parent or...
xUnit.net: Global setup + teardown?
...e in my opinion, as forgetting to decorate a single test class can lead to errors that are difficult to track down. It would be nice if xUnit created a way to truly global setup and teardown.

Detach (move) subdirectory into separate Git repository
... you can't "push" deletes to GitHub and the like. If you try you'll get an error and you'll have to git pull before you can git push - and then you're back to having everything in your history.
So if you want to delete history from the "origin" - meaning to delete it from GitHub, Bitbucket, etc - yo...
