• I need to pad IP addresses with Zeroes for each octet

  - by Felipe Alvarez

  Starting with a string of an unspecified length, I need to make it exactly 43 characters long (front-padded with zeroes). It is going to contain IP addresses and port numbers. Something like: ### BEFORE # Unfortunately includes ':' colon 66.35.205.123.80-137.30.123.78.52172: ### AFTER # Colon removed. # Digits padded to three (3) and five (5) # characters (for IP address and port numbers, respectively) 066.035.05.123.00080-137.030.123.078.52172 This is similar to the output produced by tcpflow. Programming in Bash. I can provide copy of script if required. If it's at all possible, it would be nice to use a bash built-in, for speed. Is printf suitable for this type of thing?

• New or not so well-known paradigms, syntax features and behaviours of programming languages?

  - by George B

  I've designed some educational programming languages and interpreters for them, but my problem always was that they ended up "normal" and "boring", mostly similar to some kind of existing language (ASM and BASIC). I find it really hard to come up with new ideas for syntax features, "neat things" and new or very modified programming paradigms for it. I always thought that it was hard to come up with good new things not fun/useless new things for this case. I wondered if you could help me out with your creativity: What features in terms of language syntax and built-in functions as well as maybe even new paradigms can I work into my language to keep it useless but more fun, enjoyable, interesting and/or different to program in?

• Simple addition calculator in python

  - by Krysten

  I built a very simple addition calculator in python: #This program will add two numbers entered in by the user print "Welcome!" num1 = input("Please enter in the first number to be added.") num2 = input("Please enter in the second number to be added.") sum = num1 + num2 print "The sum of the two numbers entered is: ", sum I haven't setup python yet, so I'm using codepad.org (an online compiler). I get the following error: Welcome! Please enter in the first number to be addeded.Traceback (most recent call last): Line 5, in num1 = input("Please enter in the first number to be addeded.") EOFError

• First iPhone App View Position Problem

  - by hytparadisee

  I am closely following the instructions given in the tutorial "Your First iPhone Application" on apple ADC. In the interface builder, I have set up a button positioned on the top according to the Apple Interface Guidelines. It runs without trouble if I simulate the interface in IB. However, if I run the built app, I get what is shown here. If you look at the view clearly, you will see that the entire view has been shifted up. And the magnitude of the shift is exactly the height of the status bar. And that's why the there is blank space at the bottom of the window, which was white instead of red. I have tried turning on the "Simulated Interface Elements", but that doesn't work either. The problem persists on real devices as well. However, using the "Simulate Interface" from IB looks fine. Any help is appreciated. Yun Tao

• How to convert from integer to unsigned char in C, given integers larger than 256?

  - by Alf_InPogform

  As part of my CS course I've been given some functions to use. One of these functions takes a pointer to unsigned chars to write some data to a file (I have to use this function, so I can't just make my own purpose built function that works differently BTW). I need to write an array of integers whose values can be up to 4095 using this function (that only takes unsigned chars). However am I right in thinking that an unsigned char can only have a max value of 256 because it is 1 byte long? I therefore need to use 4 unsigned chars for every integer? But casting doesn't seem to work with larger values for the integer. Does anyone have any idea how best to convert an array of integers to unsigned chars?

• Find value within a range in lookup table

  - by francis

  I have the simplest problem to implement, but so far I have not been able to get my head around a solution in Python. I have built a table that looks similar to this one: 501 - ASIA 1262 - EUROPE 3389 - LATAM 5409 - US I will test a certain value to see if it falls within these ranges, 389 -> ASIA, 1300 -> LATAM, 5400 -> US. A value greater than 5409 should not return a lookup value. I normally have a one to one match, and would implement a dictionary for the lookup. But in this case I have to consider these ranges, and I am not seeing my way out of the problem. Maybe without providing the whole solution, could you provide some comments that would help me look in the right direction? It is very similar to a vlookup in a spreadsheet. I would describe my Python knowledge as somewhere in between basic to intermediate. Many thanks in advance.

• Nginx and Django on Dotcloud

  - by jmetz

  I currently have a dotcloud app that uses django to serve everything. It works great, however, we recently had our site redone in angular.js, and I don't want to use django to serve the actual html pages (I want to just use nginx for that), but I want django to serve some links for the API we built for the angular code to use. Is it possible for me, in the same app, to configure nginx to serve some static files for particular urls, and have it send other urls for django to serve? I want nginx to serve my index.html page is a request comes in to wwww.example.com, but if a request for example.com/api/login/ comes in, I want that to be handled by django. Is this possible?

• Validate decimal number in (known) national format

  - by Álvaro G. Vicario

  PHP has many built-in functions to validate numbers but they all expect input in computer format: 1234.56. I need to validate stuff like 1,234.56 (English) or 1.234,56 (Spanish), together with some typical attributes (accepted range, max number of decimals, etc.). I started writing my own function but I soon got lost. It's easy to read the user input into a float variable but I want to be able to detect numbers with invalid formats like 1,23456.7 or 1..25. Do you have any recommendation on the subject? (Decimal and thousand characters are known beforehand and it's okay to hard-code digit groups as three, there's no need to cover Indian number format.)

• C++/CLI Missing MSVCR90.DLL

  - by Mitch

  I have a c++/cli dll that I load at runtime and which works great in debug mode. If I try and load the dll in release mode it fails to load stating that one or more dependencies are missing. If I run depends against it I am missing MSVCR90.DLL from MSVCM90.DLL. If I check the debug version of the dll it also has the missing dependency, but against the debug (D) version. I have made sure debug/release embed the manifest file. I read something about there being issues with the app loading the dll being build as Any CPU and the dll being built as x86, but I don't see how to set them both to x86. I am using VS2010. Anyway, I've been messing around for a while now and have no idea what is wrong. I'm sure someone out there knows what is going on. Let me know if I need to include additional info.

• Website image caching with Apache

  - by Piskvor

  How can I get static content on Apache to be {cached by browser} and not {checked for freshness {with every request}}? I'm working on a website hosted on Apache webserver. Recently, I was testing something with headers (Content-Type for different types of content) and saw a lot of conditional requests for images. Example: 200 /index.php?page=1234&action=list 304 /favicon.ico 304 /img/logo.png 304 /img/arrow.png (etc.) Although the image files are static content and are cached by the browser, every time an user opens a page that links to them, they are conditionally requested, to which they send "304 Not Modified". That's good (less data transferred), but it means 20+ more requests with every page load (longer page load due to all those round-trips, even with Keep-Alive and pipelining enabled). How do I tell the browser to keep the existing file and not check for newer version? EDIT: the mod_expires method works, even with the favicon.

• Fallback to another existing MIME type when the required is missing in Rails

  - by fifigyuri

  I want to extend the existing supported HTML type of my site by support for iPhone. For this I registered a new MIME type. I created a layout for iphone and also converted some of the html views to iphone version. However, I did not convert all of the html.erb files. I do not see the reason to convert all views, some of them should not change, some partials simply just remain the same. I guess there should be a solution for this case. I tried to search for ways how to fallback to an existing format, but did not find any answer. Does a way to define fallback for MIME types in Rails exist? How does it work? If it doesn't exist and thus I wanted to solve the issue not the right way, what could simply solve the task of extending an existing site by another format? Thanks for your suggestions.

• Synchronous HTTP Client with .NET sockets

  - by Ray Wits

  Does anyone know of any open source C# projects or some sample code that implement a synchronous HTTP client using sockets? I'm working on a project where I need a HTTP client using sockets. It can't use WebRequest or WebClient, nor can it use Asynchronous sockets. Don't ask. Also it would ideally be on .NET 2.0, yeah very cutting edge here. I figured the web would have tons of samples for this but suprisingly I couldn't find any. Probably because everyone is fortunate enough to use the built in APIs. If I don't find something I'll have to write it myself, which I don't really want to have to reinvent that wheel.

• List<T> add method in C#

  - by Nano HE

  Hello. As I know. List Add method works as below. List<string> cities = new List<string>(); cities.Add("New York"); cities.Add("Mumbai"); cities.Add("Berlin"); cities.Add("Istanbul"); If I designed the data structure as this List<object> lstObj = new List<object>(); if (true) // string members { cities.Add("New York"); cities.Add("Istanbul"); } else // List obj members here { List<object> AListObject= new List<object>(); cities.Add(AListObject); // how to handle this? } Does the List Add method works or not if I add different types members in the same function.

• I can't fix a broken image in Internet Explorer

  - by lewisqic

  Hi All, I have a broken image in IE that I can't seem to fix. I have tried everything I could think of so far. It works just fine in all browsers except IE. You can view the broken image here... http://74.53.164.152/~maury66/index.php?cPath=5_11 As you can see, all of the product images work except for the one for the product titled "Facial Hydrating Lotion - 120 ml/4 fl oz - For normal and oily skin types". Does anyone have any idea what would be causing this? Any advice or direction would be greatly appreciated.

• Calling HttpRequest::getRawRequestMessage() without send()

  - by danielgrad

  I am trying to call getRawRequestMessage() to get the raw HTTP content of the request described by a HttpRequest object, but I notice it always returns an empty string if I don't call send() first. Which kind of defeats my purpose (I want to send the data through other means than the HttpRequest's own send() method). Is there any other way to convert a HttpRequest object to it's raw string equivalent? To give more context: I'm working with a complex class that builds a HttpRequest object and sends requests through it and I want to add a new mode to the class that will work through raw sockets instead. The request is already built in the HttpRequest object and I would like to not have to parse the object manually to generate the HTTP message.

  I'm using dijit combobox for populating a JSON List. Also I'm using ItemFileReadStore for getting the JSON data from the server. Once the data is downloaded, when I click on the combobox it shows all the data. But I don't want the user to see all the data. The user should see the list only when he types something. I tried using queryExpr parameter-${0}*. But at that time the list is not populated.Can someone please help me to fix it? Any help will be greatly appreciated Thanks, Apps

• Custom Extension not showing up wthin experimental instance

  - by user1333524

  I have a VSIX extension that I created which shows up in Visual Studio 2010 and works as designed. However I am attempting to build some Visual Studio automation which relies on this Extension and although its present in the project where I am building my automation package, when I run the package project, the visual studio experimental solution loads no problem, however when I look within the Extension Manager I do not see my registered Extension (even though it shows up within my Visual Studio project where I am building my extension. The extension is a custom shell for LightSwitch which may be a clue as to why it is not showing within my experimental instance of Visual Studio, not sure as I see other extensions I built and registered for LightSwitch showing up. Of course my issue is that when I attempt to load a solution that has a dependency on my LightSwitch extension, which otherwise loads fine outside of the Experimental Instance, fails due to the fact it can't locate my custom extension when I try to load the solution within my experimental solution.

• customizing Django look and feel in Python

  - by user248237

  I am learning Django and got it to work with wsgi. I'm following the tutorial here: http://docs.djangoproject.com/en/1.1/intro/tutorial01/ My question is: how can I customize the look and feel of Django? Is there a repository of templates that "look good", kind of like there are for Wordpress, that I can start from? I find the tutorial counterintuitive in that it goes immediately toward customizing the admin page of Django, rather than the main pages visible to users of the site. Is there an example of a "typical" Django site, with a decent template, that I can look at and built on/modify? The polls application is again not very representative since it's so specialized. any references on this would be greatly appreciated. thanks.

• Securing input of private / protected methods?

  - by ts

  Hello, normally, all sane developers are trying to secure input of all public methods (casting to proper types, validating, sanitizing etc.) My question is: are you in your code validating also parameters passed to protected / private methods? In my opinion it is not necessary, if you securize properly parameters of public methods and return values from outside (other classes, db, user input etc...). But I am constantly facing frameworks and apps (ie. prestashop to name one) where validation is often repeated in method call, in method body and once again for securize returned value - which, I think, is creating performace overhead and is also a sign of bad design.

• Framework/tool for processing C++ unit tests with numerical output

  - by David Claridge

  Hi, I am working on a C++ application that uses computer vision techniques to identify various types of objects in a sequence of images. The (1000+) images have been hand-classified, so we have an XML file for each image containing a description of where the objects are actually located in the images. I would like to know if there is a testing framework that can understand/graph results from tests that are numeric, in this case some measure of the error in the program's classification of the images, rather than just pass/fail style unit tests. We would like to use something like CDash/CTest for running these automated tests, and viewing over time how improvements to the vision algorithms are causing the images to be more correctly classified. Does anyone know of a tool/framework that can do this?

• Can I detect unused extra parameters passed to javascript methods?

  - by Pablojim

  In Javascript I can call any method with more than the necessary amount of parameters and the extra parameters are silently ignored. e.g. letters = ['a','b','c'] //correct letters.indexOf('a') //This also works without error or warning letters.indexOf('a', "blah", "ignore me", 38) Are there ways to detect cases where this occurs? My motivation is that in my experience cases where this occurs are usually bugs. Identification of these by code analysis or at runtime would help track these errors down. These cases are especially prevalent where people are expecting alterations to base types which may not have occurred. Logging a warning where this happens e.g. Date.parse('02--12--2012', 'dd--MM--YYYY') Notes: To be clear I would like a solution that doesn't involve me sprinkling checks all over my code and other peoples' code.

• Can I have fixed typed ArrayList in C#, just like C++?

  - by Kazoom

  I have an ArrayList which contains fixed type of objects. However everytime I need to extract an object a particular index, I need to typecast it to my user defined type from object type. Is there a way in C# to declare ArrayList of fixed types just like Java and C++, or is there a work around to avoid the typecasting everytime? Edit: I apologize I forgot mentioning that I require the datastructure to be thread-safe, which List is not. Otherwise I would have just used a normal Array. But I want to save myself from the effort of explicitly locking and unlocking while writing the array. So I thought of using ArrayList, synchronize it, but it requires typecasting every time.
