• How to read and modify the colorspace of an image in c#

  - by Matthias

  I'm loading a Bitmap from a jpg file. If the image is not 24bit RGB, I'd like to convert it. The conversion should be fairly fast. The images I'm loading are up to huge (9000*9000 pixel with a compressed size of 40-50MB). How can this be done? Btw: I don't want to use any external libraries if possible. But if you know of an open source utility class performing the most common imaging tasks, I'd be happy to hear about it. Thanks in advance.

• Hierarchical data in Linq - options and performance

  - by Anthony

  I have some hierarchical data - each entry has an id and a (nullable) parent entry id. I want to retrieve all entries in the tree under a given entry. This is in a SQL Server 2005 database. I am querying it with LINQ to SQL in C# 3.5. LINQ to SQL does not support Common Table Expressions directly. My choices are to assemble the data in code with several LINQ queries, or to make a view on the database that surfaces a CTE. Which option (or another option) do you think will perform better when data volumes get large? Is SQL Server 2008's HierarchyId type supported in Linq to SQL?

• Higher than high-level web frameworks or CMS's?

  - by Ben

  I'm looking for options that allow very high-level web site development with these special characteristics: not requiring the user to program in a complex programming language not requiring the user to use GUI-like administration areas allow the user to "program" in a lightweight markup language The last point is not only about look and structure of the output but also about creating simple dynamic output. For example: listing pages fetching the content of other pages doing a site search and displaying its output dynamically show or hide parts of the page depending on login status Of course, I am not expecting a solution that provides the same possibilities like a Ruby, Python or PHP web framework. Rather I am looking for support of the "basics" that are common for web sites. Until now, I have found only one piece of software that fulfills these requirements but while it's free, it's not open source: BoltWire at http://www.boltwire.com/. Being open source is required.

• ZF1 + Doctrine 2 ODM: Call to undefined method AnnotationReader::setDefaultAnnotationNamespace

  - by Rafael

  I am trying to setup a zf1 + doctrine mongo odm 1.0.0BETA4-DEV project.

• Can one prevent Genshi from parsing HTML entities?

  - by DNS

  I have the following Python code using Genshi (simplified): with open(pathToHTMLFile, 'r') as f: template = MarkupTemplate(f.read()) finalPage = template.generate().render('html', doctype = 'html') The source HTML file contains entities such as &copy;, &trade; and &reg;. Genshi replaces these with their UTF-8 character, which causes problems with the viewer (the output is used as a stand-alone file, not a response to a web request) that eventually sees the resulting HTML. Is there any way to prevent Genshi from parsing these entities? The more common ones like &amp; are passed through just fine.

• zlib memory usage / performance. With 500kb of data.

  - by unixman83

  Is zLib Worth it? Are there other better suited compressors? I am using an embedded system. Frequently, I have only 3MB of RAM or less available to my application. So I am considering using zlib to compress my buffers. I am concerned about overhead however. The buffer's average size will be 30kb. This probably won't get compressed by zlib. Anyone know of a good compressor for extremely limited memory environments? However, I will experience occasional maximum buffer sizes of 700kb, with 500kb much more common. Is zlib worth it in this case? Or is the overhead too much to justify? My sole considerations for compression are RAM overhead of algorithm and performance at least as good as zlib.

• Concerns about reading a file in Flash 10

  - by user246114

  Hi, I'd like to read an xml file on a user's machine (which can be kind of large). There's no point in me sending the file to my server as I can do all the work I need on the file right on the client's machine. Not sure if this is a good fit though, was wondering if anyone can answer these questions before I dive in: I see at adobe's website that Flash 10 has like 94% penetration, is this true, I thought it was just released not too long ago? After opening the xml file in flash, is it possible to just throw it to a javascript function on my same page for further processing? I'd like to go into flash world for as short a time as possible. Is it at all common to use flash for file upload stuff? I heard aol/flickr are? I would need to buy flash in order to do this right, they don't have a free ide/compiler yet? Thanks

• Most used .NET namespace

  - by Michael Prewecki

  What is your most commonly used namespace in .NET. I know it will vary greatly based upon the types of projects you develop but the stack overflow audience should provide a fairly decent sample set for the types of .NET projects being developed. I'm simply interest in the name of the namespace (one namespace per answer and no one person should have more than one answer, if someone else has the same answer as you then just upvote their answer). Try to be as specific as possible (so answering System, isn't helpful). I'm after this information to help new developers focus their attention on the most common .NET namespaces...there are after all thousands of them! To start off mine is almost certainly System.Collections.Generic, I use lists of things everywhere.

• Output Path property issue on build server

  - by Jay Clarke

  I am working in the .NET 3.5 framework. I have a project that builds fine locally. I can build it on our build server when the source files are posted there. However when I am running the build process through Visual Studio 2010 I get a warning that says "C:\WINDOWS\Microsoft.NET\Framework64\v3.5\Microsoft.Common.targets: The OutputPath property is not set for this project. Please check to make sure that you have specified a valid Configuration/Platform combination. Configuration='DEV' Platform='Any CPU'" Any suggestions anyone has or if you need additional information please let me know. I have been struggling with this for a couple of days now. Thanks in advance for your help. Jay Clarke

• where should we send notification for updating many views?

  - by Thanh-Cong Vo

  Hi all, I want to ask about software design. I have a task, the view controller handles UI event for calling a model manger to perform that task. After finishing, the model manager will callback to update the view. There have also other views who care about that task, and also want to update its own view when that task is finished. So I register a Notification for that task in each views. The problem is defining where should I send Notification, in Model manager or in the View who handles event and receives the callback from Model manager? What is better design? Shoud the model care about send this "common" task, or shoud the view? Thanks

• Kendo UI, searchable Combobox

  - by user2083524

  I am using the free Kendo UI Core Framework. I am looking for a searchable Combobox that fires the sql after inserting, for example, 2 letters. Behind my Listbox there are more than 10000 items and now it takes too much time when I load or refresh the page. Is it possible to trigger the sql query only by user input like the autocomplete widget do? My code is: <link href="test/styles/kendo.common.min.css" rel="stylesheet" /> <link href="test/styles/kendo.default.min.css" rel="stylesheet" /> <script src="test/js/jquery.min.js"></script> <script src="test/js/kendo.ui.core.min.js"></script> <script> $(document).ready(function() { var objekte = $("#objekte").kendoComboBox({ placeholder: "Objekt auswählen", dataTextField: "kurzname", dataValueField: "objekt_id", minLength: 2, delay: 0, dataSource: new kendo.data.DataSource({ transport: { read: "test/objects.php" }, schema: { data: "data" } }), }).data("kendoComboBox"); </script>

• Windows Workflow foundatation scheduling.

  - by MushRoom

  If I have an ASP.NET app hosting a worflow where a trouble ticket passes through a fairly standard flow....at one point there needs to be an escalation occurring if a ticket has not been looked at or resolved in 6 months. Now lets say the 6 months have passed, but the IIS machine has been rebooted last month and not used. Will the workflow escalate the ticket? When/how does the runtime check conditions on long running processes? Does it scan through the 1000's of workflows looking...or have an events table it checks? Does it even handle this kind of out-of-process workflow? Seems like it would be a very common situation for a WF to handle but i can't seem to find any information.

• How to keep views free of authorization logic in mvc?

  - by David Lay

  I have a view to display a list of items. The user can edit, delete or create new items, but according to their authorizations they may or may not be allowed to do some of this actions. I have the requirement to display only the actions which the current user is allowed to do, but I don't want to clutter the views with authorization if-else's Despise of being a very common requirement, I can't find a real satisfactory way of doing it. My best approach so far is to provide an overload to the Html.ActionLink extension method that takes the permission to ask for, but there are going to be more complex scenarios, like hiding entire blocks of html or switching a textbox for a label+hidden. Is there a better way to do this?

• Is `hg pull --rebase` analogous to `svn update`?

  - by allyourcode

  This question assumes there's a "blessed" central repository that members of a team clone from push to when they have contributions that they want other team members to see pull from when they want to see other people's contributions. etc. If so, I would assume hg update is not analogous to svn update (why would there be two commands that do exactly the same thing?). From what I can gather, hg update more like svn revert. Is that correct? Update: My understanding of rebase is largely based on the "A common case" section on this page: http://mercurial.selenic.com/wiki/RebaseProject

• Using SharePoint user profiles to build a company phone directory

  - by Jonathan

  I'm working on a Sharepoint 2007 (MOSS Std) intranet implementation right now, and one of the things we'd like to do is replace the manually-maintained phone directory with the profile information we're importing from AD. People search is great, but I want to have a big page with all the names and phone numbers of the 150 or so people that work at the company (which means using the People Search webpart with a query hard-coded to return everyone won't work). A few quick searches haven't turned up anything, but this seems like a really common request. Can anyone help me out? I'm not opposed to buying a reasonably-priced webpart to solve this or writing some custom code, but both seem like they shouldn't be required for such a simple request.

• Silverlight, dealing with Async calls

  - by Billy

  Hi there, I have some code as below: foreach (var position in mAllPositions) { DoAsyncCall(position); } //I want to execute code here after each Async call has finished So how can I do the above? I could do something like: while (count < mAllPositions.Count) { //Run my code here } and increment count after each Async call is made ... but this doesn't seem like a good way of doing it Any advice? Is there some design pattern for the above problem as i'm sure it's a common scenario?

• Dice face value recognition

  - by Jakob Gade

  I’m trying to build a simple application that will recognize the values of two 6-sided dice. I’m looking for some general pointers, or maybe even an open source project. The two dice will be black and white, with white and black pips respectively. Their distance to the camera will always be the same, but their position on the playing surface will be random. (not the best example, the surface will be a different color and the shadows will be gone) I have no prior experience with developing this kind of recognition software, but I would assume the trick is to first isolate the faces by searching for the square profile with a dominating white or black color (the rest of the image, i.e. the table/playing surface, will in distinctly different colors), and then isolate the pips for the count. Shadows will be eliminated by top down lighting. I’m hoping the described scenario is so simple (read: common) it may even be used as an “introductory exercise” for developers working on OCR technologies or similar computer vision challenges.

• What is the difference between Java RMI and JMS?

  - by Sanoj

  When designing an distributed application in Java there seams to be a few technologies that address the same kind of problem. I have briefly read about Java Remote Method Invocation and Java Message Service, but it is hard to really see the difference. Java RMI seams to be more tightly coupled than JMS because JMS use asynchronous communication, but otherwise I don't see any big differences. What is the difference between them? Is one of them newer than the other one? Which one is more common/popular in enterprises? What advantages do they have over eachother? When is one preferred over the other? Do they differ much in how difficult they are to implement? I also think that Web Services and CORBA address the same problem.

• How to override TOMCAT Oracle ojdbc14 driver in the application?

  - by Luís Henrique Rocha

  The TOMCAT server is using an Oracle 9G ojdbc14 driver to its jndi connections in the /common/lib folder. My web application uses Maven + Spring and I'm getting the dataSource using Spring jndi features. I'm trying to bypass TOMCAT old ojdbc14 driver with a newer one (ojdbc14 10.2.0.4.0). I've tried putting the jars in the WEB-INF/lib folder as a project dependency, but it doesn't work the application keeps using the old oracle driver that is in the TOMCAT folder. I'm trying to bypass the TOMCAT oracle driver because I cannot update it to the newest version because there are lots of other projects using it. Does anyone have a clue?

• Windows Azure Platform, latest version?

  - by Vimvq1987

  I searched through internet but found nothing. The whitepapers of Windows Azure Platform say something like that: In its first release, the maximum size of a single database in SQL Azure Database is 10 gigabytes A few things are omitted in the technology’s first release, however, such as the SQL Common Language Runtime (CLR) and support for spatial data. (Microsoft says that both will be available in a future version.) I want to know that Microsoft had updated Windows Azure Platform and removed these limits or not? I decided to post this question here instead of Serverfault.com because it's more relative to programming than administration. Thank you

• How can HTML5 "replace" Flash?

  - by Kassini

  A topic of debate that's seen a resurgence since the unveiling of the iPad is the issue of Flash versus HTML5. There are those that suggest that HTML5 will one day supplant/replace Adobe Flash. I do not develop software that runs in a browser, so my (limited) understanding is: HTML is a pure-text markup language that is delivered over HTTP to a client browser. The client browser interprets the markup and renders (with varying degrees of success) the page according to an standard specification. Adobe Flash is a propriety framework for working with audio, video, sound and raster/vector graphics. It requires special authoring tools (a compiler perhaps?) and a custom player that's available as a plug-in to most common browsers. Could someone please explain (to this C/C++ developer) how it is possible from a technical/coding point-of-view that a text-based markup language (HTML5) could be considered a replacement to a multimedia framework (Flash)? Please no opinionated arguments - just technical facts.

• How to write a linter?

  - by jbdavid

  In my day job I, and others on my team write a lot of hardware models in Verilog-AMS, a language supported primarily by commercial vendors and a few opensource simulator projects. One thing that would make supporting each others code more helpful would be a LINTER that would check our code for common problems and assist with enforcing a shared code formatting style. I of course want to be able to add my own rules and, after I prove their utility to myself, promote them to the rest of the team.. I don't mind doing the work that has to be done, but of course also want to leverage the work of other existing projects. Does having the allowed language syntax in a yacc or bison format give me a leg up? or should I just suck each language statement into a perl string, and use pattern matching to find the things I don't like? (most syntax and compilation errors are easily caught by the commercial tools.. but we have some of our own extentions.)

• Replacing xcode with macports software

  - by Feynman

  I have been trying to replace everything in xcode with stuff I can get from macports. So far, I installed xcode, then macports, then used macports to install gcc, gcc_select, gmake, elf-bintools, bintools, arm-bintools (just to be sure I replaced all the bintools), and then uninstalled all of xcode. I then linked /usr/bin/make with /opt/local/bin/gmake and used gcc_select to select gcc44--the one from macports. I also exported all the bintool executable paths into the .profile path. I was sure this would work (although I should have known better after working on it for 48 hours straight), but nothing will configure, and the log files all have the common error: :info:configure configure: error: C compiler cannot create executables I have a feeling it has something to do with libraries, but I am really not sure. I use a mac 10.5.8. If this is truely 'impossible', what parts of xcode to I need for macports to work? For example, I can uninstall the xcode folder without a problem.
