Is it worth hashing passwords on the client side
...order to make sure, that such a replay attack cannot work, usually, by allowing the client to select a bunch of random bits, which are hashed along with the password, and also submitted in the clear to the server.
On the server:
generate a few bits of random
send these bits (in clear text) to th...
When do you use POST and when do you use GET?
... to provide the PUT and DELETE calls also.
But, even if you are not following RESTful principles, it can be useful to think in terms of using GET for retrieving / viewing information and POST for creating / editing information.
You should never use GET for an operation which alters data. If a se...
Which comment style should I use in batch files?
... is an actual command that just does nothing. In neither case (at least on Windows 7) does the presence of redirection operators cause a problem.
However, :: is known to misbehave in blocks under certain circumstances, being parsed not as a label but as some sort of drive letter. I'm a little fuzzy...
Why is Go so slow (compared to Java)?
...
In the next release of the Go FAQ, something similar to the following should appear.
Performance
Why does Go perform badly on benchmark
X?
One of Go's design goals is to
approach the performance of C for
comparable programs, yet on some
benchmarks it does quite poorly...
Performance surprise with “as” and nullable types
.... While the IL code for the new syntax is indeed 1 byte smaller, it mostly wins big by making zero calls (vs. two) and avoiding the unbox operation altogether when possible.
// static void test1(Object o, ref int y)
// {
// int? x = o as int?;
// if (x.HasValue)
// y = x.Value;
// }...
Retrieve specific commit from a remote Git repository
...ey are fed to us by the config machinery, as that lets our usual "last one wins" config precedence work (and entries in .git/config, for example, will override /etc/gitconfig).
So you can now do:
git config --system transfer.hideRefs refs/secret
git config transfer.hideRefs '!refs/secret/not-...
How do I expire a PHP session after 30 minutes?
... session handler, your filesystem must keep track of access times (atime). Windows FAT does not so you will have to come up with another way to handle garbage collecting your session if you are stuck with a FAT filesystem or any other filesystem where atime tracking is not available. Since PHP 4.2.3...
What is “stdafx.h” used for in Visual Studio?
...long, slow process. Compiling the huge header structures that form part of Windows API and other large API libraries is a very, very long, slow process. To have to do it over, and over, and over for every single Cpp source file is a death knell.
This is not unique to Windows but an old problem face...
CALL command vs. START with /WAIT option
...ing another batch it's a big difference,
as CALL will start it in the same window and the called batch has access to the same variable context.
So it can also change variables which affects the caller.
START will create a new cmd.exe for the called batch and without /b it will open a new window....
In what cases do I use malloc and/or new?
...to use C, you should never use malloc. Always use new." Why? What is the win here? For objects we need construction, but for memory blocks, you clearly document two ways to make coding mistakes (the more easily caught () vs [] in new and the less easily caught mismatched array vs scaler new and d...
