• buffer size for socket connection in c++

  - by wyatt

  I'm trying to build a basic POP3 mail client in C/++, but I've run into a bit of an issue. Since you have to define the buffer size when building the program, but a message can be arbitrarily large, how do you, say, get the mail server to send it to you in parts? And if this isn't the correct means of solving the problem, what is? And while I'm here, can anyone confirm for me that RFC 2822 is still the current document defining email layout? Thanks

• Python script to remove all comments from XML file

  - by Jennifer Greentree

  I am trying to build a python script that will take in an XML document and remove all of the comment blocks from it. I tried something along the lines of: tree = ElementTree() tree.parse(file) commentElements = tree.findall('//comment()') for element in commentElements: element.parentNode.remove(element) Doing this yields a weird error from python: "KeyError: '()' I know there are ways to easily edit the file using other methods ( like sed ), but I have to do it in a python script.

• How to use Rx to asynchronously query Twitter search ?

  - by Jalfp

  Hi, I'm thinking about using Rx (Reactive Framework) in order to asynchronously query Twitter search API on a given keyword. The sample app I'd like to build should be able to display new tweets in the console. Do you think it is possible to do that ? Would it be simpler than using standard programming techniques ? How would you do that ? Thank ! Jeremy

• Create all directories up to a point?

  - by Stefan Kendall

  I need to be able to build all directories up to and including the directory specified by my File object. For example, suppose I have something like this: File file = new File( "/var/a/b/c/d/" ); But only /var/ exists. I need a method that builds up to d, and I was wondering if there was a method in a java io library somewhere that does this already.

• Expression builder in Javascript or jQuery?

  - by morpheous

  I am searching for an expression builder GUI (like the one used in Microsoft Access). It can be plain Javascript or JQuery plugin. I am loathe to build my own and reinvent the wheel if one already exists - and yet, a search on Google does not find anything remotely useful. Is anyone aware of any such library/plugin or article that covers this?

• Creating vCard file in .NET Compact Framework (C#)

  - by Will

  Hi, Is there a built-in way to create vCard files in the .NET Compact Framework? If not, what is a good library for this? I have found this one which after some adaptations would seems to be able to do the job on the Compact Framework: http://thoughtproject.com/Libraries/vCard/index.htm But I'm not sure if there is not a build-in or more standard way to do it. Regards, Will

• Will the Order of my Associative Array be maintained from PHP to Javascript?

  - by Colin

  In PHP I'm running a mysql_query that has an ORDER BY clause. I'm then iterating through the results to build an associative array, with the row_id as the key. Then, I'm calling json_encode on that array and outputting the result. This page is loaded with AJAX, and defined in a Javascript variable. When I iterate through that Javascript variable, will I still have the order that was returned from the mysql_query?

• Tortoise SVN diff two trees

  - by Midhat

  Hi Consider the following situation Code was added to the trunk at revision x A branch was created The modifications of rev x were removed from trunk in rev x+10 trunk and branch goes their own ways till rev x+100 Now we need to update the branch with changes form the trunk The problem with a simple "merge a range of revisions" is that due to step 3, the initial branch modifications are being removed. Is there any way to work around this without resorting to manual merge. Version Info: TortoiseSVN 1.6.7, Build 18415 - 32 Bit , 2010/01/22 17:55:06 Subversion 1.6.9,

• How do I test how customers use my Cocoa application?

  - by John Gallagher

  I'm interested in finding out how customers use features in my Cocoa application. I want to build up statistics on which features people use and how they use them, so that I can measure the value of features I'm implementing. This feedback of course will be off by default and anonymous. Does anyone know of any frameworks that have been developed that can achieve this without me having to write stuff from scratch?

• How to program simple chat bot AI?

  - by Larsenal

  I want to build a bot that asks someone a few simple questions and branches based on the answer. I realize parsing meaning from the human responses will be challenging, but how do you setup the program to deal with the "state" of the conversation? EDIT: It will be a one-to-one conversation between a human and the bot.

• Are there localization tools which spot content strings in xaml/wpf?

  - by Noel Kennedy

  When globalizing a wpf application with static resx classes, it's very easy to miss the odd label or button that has its Content property set to a hard coded string in a particular language, ie English. These should of course be moved off to a {x:Static ...} so they can be localised for each culture. Are there any tools which can spot this and warn you? Built in to VS would be ideal, but I'm thinking that 'style cop' type build tools would do the job as well.

• Can one construct a "good" hash function using CRC32C as a base.

  - by DavidD

  Given that SSE 4.2 (Intel Core i7 & i5 parts) includes a CRC32 instruction, it seems reasonable to investigate whether one could build a faster general-purpose hash function. According to this only 16 bits of a CRC32 are evenly distributed. So what other transformation would one apply to overcome that? David
