• 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?

• 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?

• 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?

• 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.

• 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?

• LINQ Quicksort is Unstable Except When Cascading

  - by Mystagogue

  On page 64 of "LINQ To Objects Using C# 4.0" (Tony Magennis) he states that LINQ's quicksort ordering algorithm is unstable... ...although this is simply solved by cascading the result into a ThenBy or ThenByDescending operator. Huh? Why would cascading an unstable sortation into another sortation fix the result? In fact, I'd say that isn't possible. The original order, once passed through an unstable sort, is simply lost. What am I missing here?

• 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)

• 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?

• 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

• 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?

• Get CGI Fields from URL Python

  - by user299196

  When using the cgi module in Python, I can't seem to figure out how to extract CGI variables in the URL. For example if the url servercgi.py?name=user , how do I get 'name' after import cgi? For some reason, form.getvalue and form['user'] do not work but if I print the object, I see something like FieldStorage(None, None, [MiniFieldStoreage('name', 'user')]).

• 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.

• 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.

• 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?

• Who makes software validation? What are the steps of its?

  - by uzay95

  Fill in the X,Y,Z please. Software validation has X,Y,Z steps. Client have to provide X,Y,Z to the developer before starting to write software. When software finished, validation completes with doing X,Y,Z (sign, approval, test pictures, logs etc.). If we buy a general software like invoice management tool or SAP module which can modify/change for every customer, who should make the software validation?

• Calculating co-ordinate of a point on a path given a distance

  - by Alex

  I'm working on a project that surveys the condition of a road or highway using a calibrated trip computer connected to a rugged-PC. An operator keys in defect codes as they travel along a pre-defined route. I need to show an indicator on the map screen that shows the vehicles current position, taking into account the distance data from the trip computer. I know the exact lat lon co-ordinates at the starting point of each section of road, and the road is made up of a series of points. The question is: how can I calculate the lat lon co-ordinates of the vehicle assuming that it has continued on the route and traveled a certain distance (e.g. 1.4km). The co-ordinates would be 'locked onto' the road line, as shown in blue on the diagram below. Thanks, Alex

• 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 provide hyperlink in email pointing to a specific method inside gwt app (but not main page)

  - by subh

  My GWT app has a search result with orderid column as hyperlink. On clicking, it opens up another tab which shows the details. I want to expose this particular functionality externally say in an email http://www.myapp.com/XYZApp.html?orderid=1234 so that user can directly go to the details page after login to the App. In JSP world, it was pretty straightforward. Is it possible in GWT given that the call to show up the details page is not in the main GWT module (XYZApp.html)

• Implement functionality in PHP?

  - by Rachel

  How can we Implement Bisect Python functionality in PHP Implement function bisect_left($arr, $item); as a pure-PHP routine to do a binary-bisection search for the position at which to insert $item into $list, maintaining the sort order therein. Assumptions: Assume that $arr is already sorted by whatever comparisons would be yielded by the stock PHP < operator, and that it's indexed on ints. The function should return an int, representing the index within the array at which $item would be inserted to maintain the order of the array. The returned index should be below any elements in $arr equal to $item, i.e., the insertion index should be "to the left" of anything equal to $item. Search routine should not be linear! That is, it should honor the name, and should attempt to find it by iteratively bisecting the list and comparing only around the midpoint.
