• set include_path for embed files like .js and .css?

  - by John Isaacks

  OK so I now know there is a way to put all my php files in a single place and have them be able to be included without a filepath by setting an include_path like so: php_value include_path .:/pathToPHPFiles OK so now as long as my PHP files are in this directory I can include them from any subdirectory as if they were in the same directory. I am wondering if there is a trick like this for other file types like .css and .js so I can put them all in single location and embed them in a page without worring about the filepath?

• Are people really using Google App Engine, or they are just playing with it because "the cloud is co

  - by Bozho

  Since there are 1500+ questions for google-app-engine, I was wondering: what are people actually using it for? are they doing something for their companies or startups? are they just playing around with it because "the cloud is cool"? are they using it because it's the "java free hosting"? (answers from actual GAE users are preferable, but logical assumptions from others are welcome) Update: I was asking (as tagged) about the Java aspect of GAE.

• How important is it to unset variables in PHP?

  - by dd0x

  I am somewhat new to PHP and I am wondering: How important is it to unset variables in PHP? I know in languages like C we free the allocated memory to prevent leaks, etc. By using unset on variables when I am done with them, will this significantly increase performance of my applications? Also is there a benchmark anywhere that compares difference between using unset and not using unset?

• What is the best approach using JDBC for parameterizing an IN clause?

  - by Uri

  Say that I have a query of the form SELECT * FROM MYTABLE WHERE MYCOL in (?) And I want to parameterize the arguments to in. Is there a straightforward way to do this in Java with JDBC, in a way that could work on multiple databases without modifying the SQL itself? The closest question I've found had to do with C#, I'm wondering if there is something different for Java/JDBC.

• Do graphic cards have instruction sets of their own?

  - by Matt

  Do graphic cards have instruction sets of their own? I assume they do, but I have been wondering if it is proprietary or if there is some sort of open standard. Is every GPU instruction preceded by a CPU instruction or is it seamless? That is does OpenGL or DirectX call on the driver layer via the CPU which then sends a GPU instruction down the bus or is it more elaborate.

• Any benefits of using Windows Communication Foundation/ Web Services vs. a simple .aspx page for s

  - by Clay Nichols

  I'm working on a VB6 app that will do some very simple communication with a web server (passing value and getting back an anwer. Low bandwith and infrequent use). Someone suggested using WCF or Web Services. I'm wondering what the advantages are vs. just posting to an ASPX page like: Myserver.com/Functions.ASP?FunctionName=GetValue?UserName=BubbGump and returning some simple, easy to parse text, like one value per line.

• FOSS version of SQLCompare or something similar?

  - by Scott

  Actually, free is good enough, it doesn't have to be open source :) I'm currently using the Schema Compare utility of VS2008, but it doesn't have a command line interface and has some other weaknesses as well. I'm wondering what free tools others are using to provide command line schema comparisons/synchronizations? Thanks.

• arbitrary input from stdin to shell

  - by python_noob

  So I have this existing command that accepts a single argument, but I need something that accepts the argument over stdin instead. A shell script wrapper like the following works, but as I will be allowing untrusted users to pass arbitrary strings on stdin, I'm wondering if there's potential for someone to execute arbitary commands on the shell. #!/bin/sh $CMD "`cat`" Obviously if $CMD has a vulnerability in the way it processes the argument there's nothing I can do, so I'm concerned stuff like this: Somehow allow the user to escape the double quotes and pass input into argument #2 of $CMD Somehow cause another arbitary command to run
