I am using this little script to find out whether Firebug is open: if (window.console && window.console.firebug) { //is open }; And it works well. Now I was searching for half an hour to find a way to detect whether Google Chrome's built-in web developer console is open, but I couldn't find any hint. This: if (window.console && window.console.chrome) { //is open }; doesn't work. EDIT: So it seems
I was wondering if there is any way to escape a CDATA end token (]]>) within a CDATA section in an xml document. Or, more generally, if there is some escape sequence for using within a CDATA (but if it exists, I guess it'd probably only make sense to escape begin or end tokens, anyway). Basically, can you have a begin or end token embedded in a CDATA and tell the parser not to interpret it but to
Moderator note: Please resist the urge to edit the code or remove this notice. The pattern of whitespace may be part of the question and therefore should not be tampered with unnecessarily. If you are in the "whitespace is insignificant" camp, you should be able to accept the code as is. Is it ever possible that (a== 1 && a ==2 && a==3) could evaluate to true in JavaScript? This is an interview qu
This probably never happened in the real-world yet, and may never happen, but let's consider this: say you have a git repository, make a commit, and get very very unlucky: one of the blobs ends up having the same SHA-1 as another that is already in your repository. Question is, how would Git handle this? Simply fail? Find a way to link the two blobs and check which one is needed according to the c
Just installed El Capitan and can't install gem eventmachine 1.0.7. openssl is at 1.0.2a-1. Tried to use --with-ssl-dir but it seems ignored. Reported it to their github repo as well. Any suggestions are really appreciated. Thanks. $ ls /usr/local/Cellar/openssl/1.0.2a-1/include/openssl/ssl.h /usr/local/Cellar/openssl/1.0.2a-1/include/openssl/ssl.h $ gem install eventmachine -v '1.0.7' -- --with-s
What's a good way to profile a PHP page's memory usage? For example, to see how much memory my data is using, and/or which function calls are allocating the most memory. xdebug doesn't seem to provide memory information in its profiling feature. xdebug does provide it in its tracing feature. This is pretty close to what I want, except the sheer amount of data is overwhelming, since it shows memory
It was mentioned in the unset manual's page in 2009: unset() does just what its name says - unset a variable. It does not force immediate memory freeing. PHP's garbage collector will do it when it see fits - by intention as soon, as those CPU cycles aren't needed anyway, or as late as before the script would run out of memory, whatever occurs first. If you are doing $whatever = null; then you are
I want to share a latex document via git with many other people. Therefore we decided to put all the special sty files, that are not present in everyones latex-installation, into a resources directory. It would be cool, if this dir would be a superdir. of the actual working directory How exactly can I import those style files? It is important that even the dependencies of those remote styles are r
