  • Security of executing a command from php

    - by Nicolò Martini
    I'm writing a web application in which i use several thirdy party commands calling them with the exec function in PHP (for example, I render Latex formulas through a command-line program). My question is: what are the security issues of executing external command-line programs in php? What I have to be aware of? Can you give me a list of points to check? Thanks in advance.

  • How to flush the input stream in python?

    - by jinxed_coder
    I'm writing a simple alarm utility in Python. #!/usr/bin/python import time import subprocess import sys alarm1 = int(raw_input("How many minutes (alarm1)? ")) while (1): time.sleep(60*alarm1) print "Alarm1" sys.stdout.flush(); doit = raw_input("Continue (Y/N)?[Y]: ") print "Input",doit if doit == 'N' or doit=='n': print "Exiting....." break I want to flush or discard all the key strokes that were entered while the script was sleeping and only accept the key strokes after the raw_input() is executed.

  • Learning the Introspection API (used by FxCop)

    - by Anand Patel
    Microsoft's FxCop tool uses the introspection API. This introspection API could be used to develop new code analysis tools. But the introspection api is not documented well. Additionally, I was not able to figure out any blogs which explains this API in breadth and depth of it. The knowledge gained by understanding the API can also be used for writing custom FxCop rules. Does anybody knows about any blog or resources which explains the same?

  • braces for Math in LaTeX

    - by Tim
    Hi, Is there any convenient way to type in braces in Math in Latex? Especially when I have already typed in a lot of "(" and ")" instead of "\left(" and "\right)", how can I do a quick replacement? similarly for "{" and "}" and "[" and "]"? Is it important to make such changes? I am writing a thesis. Thanks and regards! BTW: I mainly edit latex file in Texmaker and I know how to use emacs.

  • Compile/use unrar C++ source for iphone app?

    - by greypoint
    Writing an app that will include the ability to decompress zip and rar files. I think I'm OK on how to handle the .zips but .rars seem a little more trouble. I noticed that rarlabs has source available but it's C++. Is there a way to compile, wrap or otherwise use this code within an iPhone app? Reference: http://www.rarlab.com/rar_add.htm Open to alternate suggestions on how to handle .rar files as well. I'm still pretty much a newbie so please explain in small words :)

  • Can I make ruby send network traffic over a specific iface?

    - by rjorgenson
    I am writing a script that grabs the external IP address along with some other information about each iface. I can't figure out how to make ruby send traffic over a specific iface(eth0 and wlan0 for example). I am currently using the open-uri library to open http://whatismyip.org and read it into a variable. def get_external_ip begin open("http://whatismyip.org") { |f| return f.read } rescue return "none" end end Is there any way to specify this at runtime of the script or from within the script itself(ideally)?

  • Are there programs that iteratively write new programs?

    - by chris
    For about a year I have been thinking about writing a program that writes programs. This would primarily be a playful exercise that might teach me some new concepts. My inspiration came from negentropy and the ability for order to emerge from chaos and new chaos to arise out of order in infinite succession. To be more specific, the program would start by writing a short random string. If the string compiles the programs will log it for later comparison. If the string does not compile the program will try to rewrite it until it does compile. As more strings (mini 'useless' programs) are logged they can be parsed for similarities and used to generate a grammar. This grammar can then be drawn on to write more strings that have a higher probability of compilation than purely random strings. This is obviously more than a little silly, but I thought it would be fun to try and grow a program like this. And as a byproduct I get a bunch of unique programs that I can visualize and call art. I'll probably write this in Ruby due to its simple syntax and dynamic compilation and then I will visualize in processing using ruby-processing. What I would like to know is: Is there a name for this type of programming? What currently exists in this field? Who are the primary contributors? BONUS! - In what ways can I procedurally assign value to output programs beyond compiles(y/n)? I may want to extend the functionality of this program to generate a program based on parameters, but I want the program to define those parameters through running the programs that compile and assigning meaning to the programs output. This question is probably more involved than reasonable for a bonus, but if you can think of a simple way to get something like this done in less than 23 lines or one hyperlink, please toss it into your response. I know that this is not quite meta-programming and from the little I know of AI and generative algorithms they are usually more goal oriented than what I am thinking. What would be optimal is a program that continually rewrites and improves itself so I don't have to ^_^

  • Java NIO Servlet to File

    - by Gandalf
    Is there a way (without buffering the whole Inputstream) to take the HttpServletRequest from a Java Servlet and write it out to a file using all NIO? Is it even worth trying? Will it be any faster reading from a normal java.io stream and writing to a java.nio Channel or do they both really need to be pure NIO to see a benefit? Thanks.

  • What is this particular type of revelation called?

    - by Lars Haugseth
    After struggling with a particular problem or bug in some part of my code for hours, without getting anywhere, I often get a sudden revelation as soon as I try to explain the problem to one of my coworkers, or while formulating it in writing for posting to some forum. Does this kind of experience have a name? Where can I read more about it and how to train it? Do any of you use this consciously in your day-to-day work?

  • How do you search between two columns using a parameter and a case when statement? SQL Server

    - by Kip Birgen
    I would like to search between to columns in a s query or a table depending on the variable on a paramenter e.g Declare @SelectAll as interger Set @SelectAll = 1 Declare @Column as interger Select mt.Column1, mtColumn2 From MyTable as mt Where Case When @SelectAll = 1 Then mt.Column1 IN(@Column) and mt.Column2 (' Selecting all") When @SelectAll = 1 Then mt.Column2 IN(@Column) and mt.Column1 (' Selecting all") End The purpose of this query is to allow the user to search between the column they choose. Further more the use of parameter is for the purposes of writing reporting services reports.

  • Looking for: C/C++ Regex library that supports Named Captures

    - by user318811
    I'm thinking about writing a small application that will help me mass rename files. I currently use an application named 'RegexRenamer', which (I'm assuming) uses the .NET regex engine. The application is fine, but is sort of clunky. So what I'm looking for is a C/C++ regex library that I can build my custom program off of. Anything that is small and lightweight is preferred (.Net seems heavy). Thanks.

  • Python Script to check website for a tag

    - by LinuxGnut
    Hello all. I'm trying to figure out how to go about writing a website monitoring script (cron job in the end) to open up a given URL, check to see if a tag exists, and if the tag does not exist, or doesn't contain the expected data, then to write some to a log file, or to send an e-mail. The tag would be something like or something relatively similar. Anyone have any ideas?
