• process incoming mail and parse out original text

  - by florin

  I have inherited a rails forum (Rails 2.3.2 I think) that alerts people of new posts/replies for the forums or threads they are watching. To make it easier for people to answer to threads I would like to enable reply-to-post, similar to basecamp and a bunch of other forums and tools out there. I would add a separator text (like "----add your reply above this line-----") in the original email. I need to: - process incoming email - extract the new text (above the separator line) - ideally strip out text like "on ... [email protected] wrote:" that is automatically added by some mail clients - identify the thread this email is referring to (either using the incoming address or the subject line) - identify the sender - post the content as new reply Any suggestions on how to get started? Any good plugins for this? I've seen many mentioning Mailman and Fetcher, are there any other and which one is the best for this little feature? Thanks!

• How do I re-set a BMP file's resolution (DPI) indicator?

  - by Joshua Fox

  I have a BMP tagged as 299 DPI resolution. I'd like to change that to 99 DPI. Importantly, the DPI marker in a BMP has no structural meaning. An image has a certain width and height in pixels. The displaying application can show the image at any width in inches. So, the DPI is just a hint. However, I am dealing with some third-party software which behaves differently depending on this marker, so I need to re-set it. I will appreciate suggestions on how to do this programmatically (especially in Java) as well as in GUI graphics tools (e.g. Gimp).

• Compiling C Source with Makefile in Windows

  - by humoeba

  I'm trying to compile a downloaded program in Windows. The program is usually run in Linux, but is programmed to also run in Windows (the code has #if defined(_WIN32)'s in it, and claims to work with borland free tools). When I try to use make from the command line, it tells me "Incorrect command line argument: -C". In the makefile, there are many lines that say "make -C" followed by a directory name. Does this syntax not work in Windows? What is a correct way to do this? Is there any way to compile this for native use in Windows with this makefile?

• Passing input to Ant's <exec> task

  - by mikek

  I have an Ant script running a standard -task after taking in an inputed password: <input message="Password:" addproperty="password"> <handler classname="org.apache.tools.ant.input.SecureInputHandler" /> </input> <exec executable="/bin/sh" input="${password}" failonerror="true"> <arg line='-c "myScript.sh"' /> </exec> The script myScript.sh prompts the user for a password, and, it was my understanding that from the Ant documentation that input is supposed relay input into whatever the <exec> task is executing, but instead I get (for entering the password foobar) [exec] Failed to open /usr/local/foobar which is followed by a stack trace from my script complaining about an incorrect password...so obviously I've understood the documentation wrong. Does anybody know how to handle prompted input from external scripts in Ant?

• Finding PHP dependencies

  - by JW

  Are there any tools that can list the names of classes used by a PHP file? For example, if I ran it on this file: <? class Test { public function __construct(Obj1 $x) { $y = new Obj2(); $str = "Obj3"; $z = new $str(); } } ?> it would report "Obj1" and "Obj2". If it were really smart it might report "Obj3" as well, but that's not essential. I'm trying to package up some code, and I want some help making sure that I didn't miss any dependencies. There's something called PHP_Depend, which can graph the number of dependencies, but can't report what they are.

• Structure of open source project's repository

  - by hokkaido

  I'm in the beginning of starting a small open source project. When cloning the main repository one gets a complete build environment with all the libraries and all the tools needed to make an official installer file, with correct version numbers. I like the fact that anyone who wants to contribute can clone the repository and get started with anything they want. But I'm thinking this makes it to easy for Evil People to create malicious installers and release into the wild. How should it be structured? What do you recommend including in the repository, versus keeping on the build server only?

• How to analyse Wikipedia article's data base with R?

  - by Tal Galili

  Hi all, This is a "big" question, that I don't know how to start, so I hope some of you can give me a direction. And if this is not a "good" question, I will close the thread with an apology. I wish to go through the database of Wikipedia (let's say the English one), and do statistics. For example, I am interested in how many active editors (which should be defined) Wikipedia had at each point of time (let's say in the last 2 years). I don't know how to build such a database, how to access it, how to know which types of data it has and so on. So my questions are: What tools do I need for this (besides basic R) ? MySQL on my computer? RODBC database connection? How do you start planning for such a project?

• Porting library from Java to Python

  - by Mike Griffith

  I'm about to port a smallish library from Java to Python and wanted some advice (smallish ~ a few thousand lines of code). I've studied the Java code a little, and noticed some design patterns that are common in both languages. However, there were definitely some Java-only idioms (singletons, etc) present that are generally not-well-received in Python-world. I know at least one tool (j2py) exists that will turn a .java file into a .py file by walking the AST. Some initial experimentation yielded less than favorable results. Should I even be considering using an automated tool to generate some code, or are the languages different enough that any tool would create enough re-work to have justified writing from scratch? If tools aren't the devil, are there any besides j2py that can at least handle same-project import management? I don't expect any tool to match 3rd party libraries from one language to a substitute in another.

• hibernate distributed 2nd level cache options

  - by ishmeister

  Not really a question but I'm looking for comments/suggestions from anyone who has experiences using one or more of the following: EhCache with RMI EhCache with JGroups EhCache with Terracotta Gigaspaces Data Grid A bit of background: our applications is read only for the most part but there is some user data that is read-write and some that is only written (and can also be reasonably inaccurate). In addition, it would be nice to have tools that enable us to flush and fill the cache at intervals or by admin intervention. Regarding the first option - are there any concerns about the overhead of RMI and performance of Java serialization?

• Moving webshop storage to NoSQL solution

  - by mare

  If you had a webshop solution based on SQL Server relational DB what would be the reasons, if any, to move to NoSQL storage ? Does it even make sense to migrate datastores that rely on relations heavily to NoSQL? If starting from scratch, would you choose NoSQL solution over relational one for a webshop project, which will, after a while, again end up with a bunch of tables like Articles, Classifications, TaxRates, Pricelists etc. and a magnitude of relations between them? What's the support like in .NET (4.0) for MongoDB or MongoDB's support for .NET 4.0? Can I count on rich code generation tools similar to EF wizard, L2SQL wizard etc. for MongoDB? Because as what I have read so far, NoSQL's are mostly suited for document storage, simpler object models. Your answer to this question will help me make the right infrastructure design decisions.

• .NET: efficient way to produce a string from a Dictionary<K,V> ?

  - by Cheeso

  Suppose I have a Dictionary<String,String>, and I want to produce a string representation of it. The "stone tools" way of doing it would be: private static string DictionaryToString(Dictionary<String,String> hash) { var list = new List<String> (); foreach (var kvp in hash) { list.Add(kvp.Key + ":" + kvp.Value); } var result = String.Join(", ", list.ToArray()); return result; } Is there an efficient way to do this in C# using existing extension methods? I know about the ConvertAll() and ForEach() methods on List, that can be used to eliminate foreach loops. Is there a similar method I can use on Dictionary to iterate through the items and accomplish what I want?

• Syntax Highlighting in a ListBox

  - by ph0enix

  Hi all, I've searched the web and I can't seem to find anything that will work for me. I've seen plenty of discussion, and even some fairly extensible open-source tools, for code editors that provide line numbers and syntax highlighting. Here's my dilemma... I'm working on a "digital code review" project in C#.NET that allows users to specify source files, add them to a particular session, and other users can make comments and line references to the files being reviewed. Basic requirements: Must be written in C#.NET I don't need to be able to edit the text in the text box Users need to be able to select a line (or multiple lines), to make line references. It seems to me that I need some fancy implementation of a ListBox control (not a drop-down list) that has some OwnerDraw capabilities to add line numbers and syntax highlighting. Unfortunately, I haven't had any luck putting it together myself, and I can't seem to find a control that's already been written or a reference on how I might be able to accomplish this. Any suggestions??

• Second CSS class not working in IE8.

  - by ProfK

  I have the following div being rendered to the client, but on IE, the checked-yes class is ignored. If I view the target element in the 'Developer Tools', that class is completely missing from the Style panel. The shift-item-present class is attached server side, and the checked-yes class client side, depending on the present attribute of the parent row, also shown below. <td><div class="shift-item-present checked-yes" jQuery1272958392665="94"/></td> Parent row: <tr class="shift-item" id="ctl00_mainContentPlaceHolder_ctl00_shiftList_ctl01_shiftRow" present="True" shift-id="641" jQuery1272958392665="64"> The page works perfectly in FF

• Clear sqlalchemy reflection cache

  - by OrganicPanda

  Hi all, I'm using sqlalchemy's reflection tools to get a Table object. I do this because these tables are dynamic and tables/columns can change. Here's the code I'm using: def getTableByReflection(self, tableName, metadata, engine): return Table(tableName, metadata, autoload = True, autoload_with = engine) The problem is that when the above code is run twice it seems to return the same results regardless of whether or not the columns have changed. I have tried refreshing using the mysession.refresh(mytable) but that fails because the table is not attached to any metadata - which makes sense but then why am I seeing cached results? Is there any way to tell the metadata/engine/session to forget about this table and let me load it cleanly?

• Uninstalling user install of Apache on Mac Mini

  - by Zeophlite

  I got a MacMini at work for development, and was asked to follow this article to install SVN on it: http://developer.apple.com/tools/subversionxcode.html The article assumes that only Apache 1.3 was installed and asks the reader to install Apache 2. I've since learned that the MacMini has Apache 2 already installed. So basically I've installed two versions of Apache 2. The preinstalled one has access to PHP, so I wanted to remove my version, but I'm unsure of how. My version has httpd.conf stored at: /usr/local/apache2/conf/httpd.conf And the preinstalled version has it stored at: /etc/apache2/httpd.conf, which I believe is an alias for /private/etc/apache2/httpd.conf Thanks for your help

• Web and stand-alone apps development tendency

  - by Narek

  There is a strong tendency of making web apps and even seems that very soon a lot of features will be available online so that for every day use people will have all necessary software free online and they will not need to install any software locally. Only specific (professional) tools that usually people don’t use at home will not be available as a web app. So my question, how do you imagine selling software that was necessary for everyday use and was not free (seems they can't make money any more by selling their product – no need of those products). And what disadvantages have web apps, that is to say, what is bad to use software online compared with having the same software locally (please list)? Please do not consider this question not connected with programming, as I really would like to have a little statistics from professional programmers who are aware from nowday’s tendency of software and programming. Thanks.

• HTML, Javascript, PHP and Actionscript all in one Eclipse install (2010)

  - by ThunderChunky_SF

  I just wanted to poll the community and see which plugins people are currently using to get all of these different technologies running in Eclipse. I saw this thread which mentioned Spket & WPT: http://stackoverflow.com/questions/1575617/eclipse-which-plugins-for-html-javascript But I noticed that Spket doesn't seem to have been updated since October of 2009 so I'm wondering if it's still a good tool to use. I'm not sure what would be best for PHP since it seems like some of the tools are disjointed at the moment. For Actionscript I know I can just install the latest Flash Builder plugin and be done. Any suggestions are greatly appreciated.

• .NET vs Mono differences in Development

  - by jason

  I'm looking into Mono and .NET C#, we'll be needing to run the code on Linux Servers in the future when the project is developed. At this point I've been looking at ASP.NET MVC and Mono I run an ubuntu distro and want to do development for a web application, some of the other developers use windows and run other .NET items with Visual Studio. What does Mono not provide that Visual Studio does? If running this on Linux later shouldn't we use Mono Develop ? Is there some third party tools or addin's that might be an issue with Mono later?

• drop-down combo box-like functionality for queries.

  - by Frank Developer

  Is it possible to provide the following type of fuctionality with informix client tools? As the user types the first two characters of a name, the drop-down list is empty. At the third character, the list fills with just the names beginning with those three characters. At the fourth character, MS-Access completes the first matching name (assuming the combo's AutoExpand is on). Once enough characters are typed to identify the customer, the user tabs to the next field. The time taken to load the combo between keystrokes is minimal. This occurs once only for each entry, unless the user backspaces through the first three characters again. If your list still contains too many records, you can reduce them by another order of magnitude by changing the value of constant conSuburbMin from 3 to 4.

• .net exception pool

  - by javier

  I want to create a mecanism in a large .net application to handle all the exceptions in the application, and to save the error messages (in db or log file) so these errors can be fixed, and so we are aware of the problems in the application. Does anyone know a good way of creating a library to handle and process all the exceptions?. Are there any tools around that can simplify my task. What aproach would you suggest me to take.... If you previously implemented something similar to what I want to do, I do want to heard from you Thanks all

• Netbeans or Eclipse for C++?

  - by Robert Gould

  I'm currently working on a pet project and need to do C++ development on Windows, Mac, Linux, and Solaris, and I've narrowed it down to Netbeans and Eclipse, so I was wonderig which is more solid as a C++ editor. I just need solid editing, good autocompletion for templated code ad external libraries, and project file management, the build tools are external, so thats irrelevant here, for my comparison. Thus which is a better choice? Note: I know I should be using emacs or vim, but the issue is, my theory at least, that I'm left handed, so I use my right side (design,creativity) of the brain more than the left side (logic, memory), so I just simply cannot use emacs or vim, my brain simply isn't compatible, I tried them many times too, even used emacs for a few months but it drove me crazy... Thanks

• What would be a good starting point for development of a 3D application for representation of struct

  - by Lela Dax

  I was thinking QT on OpenGL. Multiplatform ability and being able to be closed (at no cost) at a later point would be important points. But I'm very interested in finding a way that is not only viable but also has the least amount of reinvention of the wheel. e.g. "Why not Ogre? A ready powerful 3D engine without reinventing that part". But I'm very uncertain in what is the optimal collection of tools for that job.

• Is Microsoft CCR gaining any traction?

  - by spender

  Microsoft's Concurrency and Coordination Runtime quite literally saved a project that was running into major issues with deadlocking. Since then I find that I use it more and more frequently for almost anything that requires asynchronous coding producing results that run lighter and faster than before. I can honestly state that it has transformed the way I think about multithread/multicore dev. Despite my personal love for CCR, there appears to be very little buzz surrounding it on the web and was wondering if anyone can offer any reason for this. Are there better alternatives, or is it a lack of promotion from MS, or are people simply happy with the existing tools?

• RemoteWebDriver InternetExplorer navigate().to() timeout?

  - by the qwerty

  i was running a test remotely on internet explorer, and when using navigate().to() selenium returns me this: "12:13:58.770 INFO - WebDriver remote server: Exception: The driver reported that the command timed out. There may be several reasons for this. Check that the destinationsite is in IE's 'Trusted Sites' (accessed from Tools-Internet Options in the 'Security' tab) If it is a trusted site, then the request may have taken more thana minute to finish." i've done what's said. but when looking at the browsers the page is loaded, but still this message continues. i've already tried as simon told me: "(16:32:54) simonstewart: ponto: http://code.google.com/p/selenium/wiki/FrequentlyAskedQuestions#Q:_The_does_not_work_well_on_Vista._How_do_I_get_it_to_work_as_e " but did not solve. could it be google analytics that on the background is getting data or something like that? ps: i ran the test on firefox and it works well. i've tried on Windows 7 and Windows XP, and Internet Explorer 7 and Internet Explorer 8.

• Automating builds from subversion tags

  - by Ajaxx

  I'm trying to automate the build process for engineering group. As part of that automation, I'm trying to get to a point where the act of applying a specific tag that adheres to a pattern will kick off an automated process that will do the following: Check out source code Create a build script from a template Build the project I'm pretty certain I could do this with a post-hook in subversion, but I'm trying to figure out a way to do this with something other than a subversion hook. Would it make sense to monitor the tags directory in the subversion repository to kick off my workflow? Are there any decent tools that help with this (.NET would be great if possible). Am I better off just writing an engine to do this? My preferences: Existing product that does all or part of this If development work needs to occur, .NET is preferable Works with Windows (we've got a Linux based repo, but builds all occur on windows)
