• Clean URLs for images

  - by Albert

  I'm unable to get a working .htaccess that should accept clean URLs to load images. I mean, for example, if a user type this: http://mysite.com/image/example It works perfectly, as my PHP process and parse it. However, if the user type: .../image/example.jpg It doesn't work. I mean, if a user writes that, I want to load the module with the example.jpg as a parameter, I don't want to load the image at all! Thanks in advance.

• Guidelines for calling controller methods in helper modules?

  - by keruilin

  Few questions: Is it possible to call a controller method in a helper module (e.g., application helper)? If so, how does the helper handle the rendering of views? Ignore it? In what instances would you want to call a controller method from a helper? Is it bad practice? Do you have any sample code where you're calling controller methods in helper?

• How to import modules in Google App Engine?

  - by BrianLy

  I have created a simple GAE app based on the default template. I want to add an external module like short_url. How do I do this? The directions that I have found so far are confusing and GAE doesn't seem to use PYTHONPATH for obvious reasons I guess.

• Debugging an httpmodule on the asp.net development server

  - by Caveatrob

  Hi, I want to integrate some http modules in my asp.net application (v 3.5, visual studio 2008) and I'm not sure how to debug or use such modules while debugging in the asp.net development server that fires when I run the web app. Do I need to include the module source in the solution or can I just drop the DLL into BIN? I'm from the 1.1 world and am not yet used to the asp.net development server.

• Do you know any other programming languages that have interactive mode like Python?

  - by systempuntoout

  Python language has a well known feature named interactive mode where interpreter can read commands directly from tty. I tipically use this mode to test if a given module is in the classpath or to play around and test some snippets. Do you know any other programming languages that has Interactive Mode?

• Rails - why would a model inside RAILS_ROOT/lib not be available in production mode?

  - by sa125

  Hi - I have a class located inside RAILS_ROOT/lib folder, which I use in one of my helpers, and it works great in development. When I switch to production, the application throws a NameError (uninitialized constant SomeHelper::SomeClass), and I have to load it manually in the helper: load "#{Rails.root}/lib/some_class.rb" module SomeHelper def some_method sc = SomeClass.new # blah end end I was under the impression that everything inside RAILS_ROOT/lib/* should be available all to the app - is there anything I need to configure to make this happen in prod mode? thanks.

• Creating a Rails query from a hash of user input

  - by Jamie

  I'm attempting to create a fairly complex search engine for a project using a variable number of search criteria. The user input is sorted into an array of hashes. The hashes contain the following information: { :column => "", :value => "", :operator => "", # Such as: =, !=, <, >, etc. :and_or => "", # Two possible values: "and" and "or" } How can I loop through this array and use the information in these hashes to make an ActiveRecord WHERE query?

• Ruby RegEx not matching valid expression

  - by Matthew Carriere

  I have the following expression: ^\w(\s(+|-|\/|*)\s\w)*$ This simply looks to match a mathematical expression, where a user is prompted for terms separated by basic operators (ex: price + tax) The user may enter more than just 2 terms and one operator (ex: price + tax + moretax) I tested this expression in Rubular http://rubular.com/ With the terms: a + a (MATCH) a + a + a (MATCH) a + a + a + a a a + a a Everything works, but when I use it in Ruby it does not work! expression =~ /^\w(\s(+|-|\/|*)\s\w)*$/ I started picking the expression apart and noticed that if I remove the start of line caret it finds matches but isn't correct. a + a (MATCH) a a (MATCH) <-- this is not correct Why is this expression not working in Ruby code? (I am using Ruby 1.8.7 p174)

• How does this C# asp.net random password code work?

  - by quakkels

  Hello all, I'm new to .NET and C# and I'm trying to figure out how this code works: public static string CreateRandomPassword(int PasswordLength) { String _allowedChars = "abcdefghijkmnopqrstuvwxyzABCDEFGHJKLMNOPQRSTUVWXYZ23456789"; Byte[] randomBytes = new Byte[PasswordLength]; RNGCryptoServiceProvider rng = new RNGCryptoServiceProvider(); rng.GetBytes(randomBytes); char[] chars = new char[PasswordLength]; int allowedCharCount = _allowedChars.Length; for(int i = 0;i<PasswordLength;i++) { /// /// I don't understand how this line works: /// chars[i] = _allowedChars[(int)randomBytes[i] % allowedCharCount]; } return new string(chars); } I think I've got a pretty good handle on most of this. I haven't been able to understand the following line: chars[i] = _allowedChars[(int)randomBytes[i] % allowedCharCount]; I understand that the code generates random binary numbers and uses those random numbers in the for loop to select a character from the _allowedChars string. What I don't get is why this code uses the modulous operator (%) to get the _allowedChars index value. Thanks for any help

• Quote POSIX shell special characters in Python output

  - by ??O?????

  There are times that I automagically create small shell scripts from Python, and I want to make sure that the filename arguments do not contain non-escaped special characters. I've rolled my own solution, that I will provide as an answer, but I am almost certain I've seen such a function lost somewhere in the standard library. By “lost” I mean I didn't find it in an obvious module like shlex, cmd or subprocess. Do you know of such a function in the stdlib?

• Setuptools not passing arguments for entry_points

  - by Austin

  I'm using setuptools for a Python script I wrote After installing, I do: $ megazord -i input -d database -v xx-xx -w yy-yy Like I would if I was running it ./like_this However, I get: Traceback (most recent call last): File "/usr/local/bin/megazord", line 9, in <module> load_entry_point('megazord==1.0.0', 'console_scripts', 'megazord')() TypeError: main() takes exactly 1 argument (0 given) Which looks like setuptools is not sending my arguments to main() to be parsed (by optparse) Here's my setuptools config for entry_points: entry_points = { 'console_scripts': [ 'megazord = megazord.megazord:main', 'megazord-benchmark = megazord.benchmark:main', 'megazord-hash = megazord.mzhash:main', 'megazord-mutate = megazord.mutator:main', ] } Any ideas?

• static arrays defined with unspecified size, empty brackets?

  - by ahmadabdolkader

  For the C++ code fragment below: class Foo { int a[]; // no error }; int a[]; // error: storage size of 'a' isn't known void bar() { int a[]; // error: storage size of 'a' isn't known } why isn't the member variable causing an error too? and what is the meaning of this member variable? I'm using gcc version 3.4.5 (mingw-vista special) through CodeBlocks 8.02. On Visual Studio Express 2008 - Microsoft(R) C/C++ Optimizing Compiler 15.00.30729.01 for 80x86, I got the following messages: class Foo { int a[]; // warning C4200: nonstandard extension used : zero-sized array in struct/union - Cannot generate copy-ctor or copy-assignment operator when UDT contains a zero-sized array }; int a[]; void bar() { int a[]; // error C2133: 'a' : unknown size } Now, this needs some explaination too.

• How can I list the properties of an object programmatically in VB6?

  - by Gregory Higley

  A friend of mine is working on a legacy VB6 project. I haven't touched that language in ten years, so I'm pretty rusty. Anyway, is there any kind of reflection API for VB6? Specifically, he needs a way to iterate the properties (and types) of a user-created Class. (In other words, not an external COM object, but an internal "Class Module" as it's called.) How can this be done?

• Firefox extension file structure best practice

  - by user353969

  Is it a good practice to put js files of the "content" folders in inner folders representing their logical module? For example have a "datalayer" and "view" folders? I looked into some well known extensions, such as Firebug, and saw no such devision. I'm a Java developer so its seems much more natural to divide the files logically.

• apache mod_proxy_html on Ubuntu ProxyHTMLEnable not working

  - by intargc

  I'm trying to use mod_proxy_html on Ubuntu which I installed from apt-get. The module is loading properly and all ProxyHTML* directives work except for the one that matters the most. When I do "ProxyHTMLEnable on" in my apache2.conf or vhost conf files, apache complains that it's an invalid directive and I must have misspelled it. Is anyone else having this issue on Ubuntu and what can be done to fix it?

• python subprocess block

  - by MW

  Hello. I'm having a problem with the module subprocess. I'm running a script from python through: subprocess.Popen('./run_pythia.sh',shell=True).communicate() and sometimes it just blocks and it doesn't finish to execute the script. Before I was using .wait() instead of .communicate() but then because of this: http://dcreager.net/2009/08/06/subprocess-communicate-drawbacks/ I changed to .communicate(). Nevertheless the problem continues. Can anyone help me?

• Help using Horner's rule and Hash Functions in JAVA?

  - by Matt

  I am trying to use Horner's rule to convert words to integers. I understand how it works and how if the word is long, it may cause an overflow. My ultimate goal is to use the converted integer in a hash function h(x)=x mod tableSize. My book suggests, because of the overflow, you could "apply the mod operator after computing each parenthesized expression in Horner's rule." I don't exactly understand what they mean by this. Say the expression looks like this: ((14*32+15)*32+20)*32+5 Do I take the mod tableSize after each parenthesized expression and add them together? What would it look like with this hash function and this example of Horner's rule?

• Dynamically allocated structure and casting.

  - by Simone Margaritelli

  Let's say I have a first structure like this: typedef struct { int ivalue; char cvalue; } Foo; And a second one: typedef struct { int ivalue; char cvalue; unsigned char some_data_block[0xFF]; } Bar; Now let's say I do the following: Foo *pfoo; Bar *pbar; pbar = new Bar; pfoo = (Foo *)pbar; delete pfoo; Now, when I call the delete operator, how much memory does it free? sizeof(int) + sizeof(char) Or sizeof(int) + sizeof(char) + sizeof(char) * 0xFF ? And if it's the first case due to the casting, is there any way to prevent this memory leak from happening? Note: please don't answer "use C++ polymorphism" or similar, I am using this method for a reason.

• How to model a social news feed on Google App Engine

  - by PEZ

  We want to implement a "News feed" where a user can see messages broadcasted by her friends, sorted with newest message first. But the feed should reflect changes in her friends list. (If she adds new friends, messages from those should be included in the feed, and if she removes friends their messages should not be included.) If we use the pubsub-test example and attach a recipient list to each message this means a lot of manipulation of the message recipients lists when users connect and disconnect friends. We first modeled publish-subscribe "fan out" using conventional RDBMS thinking. It seemed to work at first, but then, since the IN operator works the way it does, we quickly realized we couldn't continue on that path. We found Brett Slatkin's presentation from last years Google I/O and we have now watched it a few times but it isn't clear to us how to do it with "dynamic" recipient lists. What we need are some hints on how to "think" when modeling this.
