  • Any known orchard cms case studies ?

    - by Georges
    Hi, We're looking into using orchard cms for a project. I know the CMS hasn't been around for a long time, but I was wondering if there were any known high profile and successful case studies using orchard cms or its predecessor Oxite ? Thanks.

  • .NET Expression Trees Tutorial

    - by zoman
    I've been looking for a good tutorial on Expression trees (C#) for a while, but no luck so far. Most of the stuff I've found on the Web was too high level and very basic. Does anyone know some decent tutorial that goes beyond the fundamentals?

  • Objective C for beginners

    - by Golfgod130
    I was just asked to talk about Objective C to a bunch of High School student for 20 minutes. They have no experience with programming at all. What topics should I cover? Should I define vocab such as Method, Class, Variable? Or should I do something else? Any comments are helpful!

  • Offloading to HLSL/GPU without displaying?

    - by George R
    As far as I know, certain mathematical functions like FFTs and perlin noise, etc. can be much faster when done on the GPU as a pixel shader. My question is, if I wanted to exploit this to calculate results and stream to bitmaps, could I do it without needing to actually display it in Silverlight or something? More specifically, I was thinking of using this for large terrain generation involving lots of perlin and other noises, and post-processing like high passes and deriving normals from heightmaps, etc, etc.

  • Android: manifest targetSdkVersion change resulted in: icon not visible, widget no longer works, and

    - by Casey
    I recently upgraded my Android app to support multiple resolutions. Previously, my Android.manifest file had a line: To support multiple density and resolution devices, I changed this to: <supports-screens android:smallScreens="false" android:normalScreens="true" android:largeScreens="true" android:anyDensity="true" /> <uses-sdk android:minSdkVersion="3" android:targetSdkVersion="4" /> I then added a couple of new directories, like drawable-hdpi-v4 and drawable-long-hdpi-v4 that includes the high-res versions of the graphics. That's about it. Ever since releasing this update, there have been a decent number of users complaining about various problems: - the app icon doesn't appear (I did not create a high res version of the icon) - the home screen widget no longer works, even if they delete and re-add it (this code did not change with the update). I've had a user send me their error log, which shows: 03-19 20:59:41.617 W/ActivityManager( 1854): Unable to launch app com.alt12.babybump/10078 for broadcast Intent { action=android.appwidget.action.APPWIDGET_UPDATE flags=0x4 comp={com.alt12.babybump/com.alt12.babybump.WidgetGirl} (has extras) }: process is bad There is one questionable section in my existing widget code that may be relevant: @Override public void onReceive(Context context, Intent intent) { // v1.5 fix that doesn't call onDelete Action final String action = intent.getAction(); if (AppWidgetManager.ACTION_APPWIDGET_DELETED.equals(action)) { final int appWidgetId = intent.getExtras().getInt( AppWidgetManager.EXTRA_APPWIDGET_ID, AppWidgetManager.INVALID_APPWIDGET_ID); if (appWidgetId != AppWidgetManager.INVALID_APPWIDGET_ID) { this.onDeleted(context, new int[] { appWidgetId }); } } else { super.onReceive(context, intent); } } And perhaps most troublesome: the sqlite database is no longer accessible/writeable for some users so their data is no longer available. I did add the WRITE_EXTERNAL_STORAGE permission to the manifest. This is only happening to certain users and it tends to be HTC Eris users. In that error log I see things such as: 03-19 16:00:56.173 E/FlurryAgent( 4791): java.io.FileNotFoundException: /data/data/com.alt12.babybump/files/.flurryagent.-2333f5cb 03-19 16:00:56.173 E/FlurryAgent( 4791): at org.apache.harmony.luni.platform.OSFileSystem.open(OSFileSystem.java:231) 03-19 16:01:09.393 E/Database( 4791): sqlite3_open_v2("/data/data/com.alt12.babybump/databases/uitematmamad.db", &handle, 6, NULL) failed 03-19 16:01:09.393 W/System.err( 4791): android.database.sqlite.SQLiteException: unable to open database file It's as if the update has caused a new process and it can't access the old process's data, or something. Any help appreciated!

  • Why is Html.DropDownList() producing <select name="original_name.name"> instead of just <select name

    - by DanM
    I have an editor template whose job is to take a SelectList as its model and build a select element in html using the Html.DropDownList() helper extension. I'm trying to assign the name attribute for the select based on a ModelMetadata property. (Reason: on post-back, I need to bind to an object that has a different property name for this item than the ViewModel used to populate the form.) The problem I'm running into is that DropDownList() is appending the name I'm providing instead of replacing it, so I end up with names like categories.category instead of category. Here is some code for you to look at... SelectList.ascx <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<System.Web.Mvc.SelectList>" %> <%= Html.DropDownList( (string)ViewData.ModelMetadata.AdditionalValues["PropertyName"], Model) %> Resulting HTML <select id="SkillLevels_SkillLevel" name="SkillLevels.SkillLevel"> <option value="1">High</option> <option value="2">Med</option> <option selected="selected" value="3">Low</option> </select> Expected HTML <select id="SkillLevels_SkillLevel" name="SkillLevel"> <option value="1">High</option> <option value="2">Med</option> <option selected="selected" value="3">Low</option> </select> Also tried <%= Html.Encode((string)ViewData.ModelMetadata.AdditionalValues["PropertyName"])%> ...which resulted in "SkillLevel" (not "SkillLevels.SkillLevel"), proving that the data stored in metadata is correct. and <%= Html.DropDownList( (string)ViewData.ModelMetadata.AdditionalValues["PropertyName"], Model, new { name = (string)ViewData.ModelMetadata.AdditionalValues["PropertyName"] }) %> ...which still resulted in <select name=SkillLevels.Skilllevel>. Questions What's going on here? Why does it append the name instead of just using it? Can you suggest a good workaround? Update: I ended up writing a helper extension that literally does a find/replace on the html text: public static MvcHtmlString BindableDropDownListForModel(this HtmlHelper helper) { var propertyName = (string)helper.ViewData.ModelMetadata.AdditionalValues["PropertyName"]; var compositeName = helper.ViewData.ModelMetadata.PropertyName + "." + propertyName; var rawHtml = helper.DropDownList(propertyName, (SelectList)helper.ViewData.Model); var bindableHtml = rawHtml.ToString().Replace(compositeName, propertyName); return MvcHtmlString.Create(bindableHtml); }

  • Replacement for C low level programming?

    - by Sauron
    So C obviously has a pretty dominant low level programming stronghold.....but is anything coming out that challenges/wants to replace it? Python/C#/etc all seem to be aimed at very high level, but when it comes down to nitty-gritty low level stuff C seems to be king and I haven't seen much "try" to replace that? Is there anything out there, or does learning C for low level stuff seem to be the standard?

  • Upgrade guide for Kohana 3.0.9 (from 3.0.8)

    - by Darryl Hein
    Is there an upgrade guide for Kohana 3.0.9 from 3.0.8. I'm looking for something like what jQuery provides when they release a new version. It allows for a quick scan of the changes to notice if there's anything I could use or would change how I've done things. The resolved issues are part of this, but I'm looking for something more high level. The issues require reading everything in each issue and it's often hard to understand what's actually changed.

  • Java EE technologies after learning SE?

    - by jlafay
    Ok so there are lots of nifty little technologies included in Java EE. When one learns SE, where should they go from there? I think what I'm looking for is more abstract/high level technologies that pertain to EE. I want to learn more and it seems to be difficult to find a book to transition into EE from SE. Where should I go from here?

  • Refactoring method with many conditional return statements

    - by MC.
    Hi, I have a method for validation that has many conditional statements. Basically it goes If Check1 = false return false If Check2 = false return false etc FxCop complains that the cyclomatic complexity is too high. I know that it is not best practice to have return statements in the middle of functions, but at the same time the only alternative I see is an ugly list of If-else statements. What is the best way to approach this? Thanks in advance.

  • How are hash functions like MD5 unique?

    - by Aly
    Im aware that MD5 has had some collisions but this is more of a high level question about hashing functions. If MD5 hashes any arbitrary string into a 32-digit hex value, then according to the Pigeonhole Principle surely this can not be unique as there are more unique arbitrary strings than there are unique 32-digit hex values

  • Event not bubbling in some Browsers when clicked on Flash

    - by 166_MMX
    Environment: Windows 7, Internet Explorer 8, Flash ActiveX 10.1.53.64, wmode=transparent Just wrote a small test page that you can load in IE and Firefox or any other Browser. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Event bubbling test</title> </head> <body onclick="alert('body');" style="margin:0;border-width:0;padding:0;background-color:#00FF00;"> <div onclick="alert('div');" style="margin:0;border-width:0;padding:0;background-color:#FF0000;"> <span onclick="alert('span');" style="margin:0;border-width:0;padding:0;background-color:#0000FF;"> <object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://fpdownload.macromedia.com/get/shockwave/cabs/flash/swflash.cab#version=7,0,0,0" width="159" height="91" id="flashAbout_small" align="absmiddle"> <param name="movie" value="http://www.adobe.com/swf/software/flash/about/flashAbout_info_small.swf"/> <param name="quality" value="high"/> <param name="bgcolor" value="#FFFFFF"/> <param name="wmode" value="transparent"/> <embed src="http://www.adobe.com/swf/software/flash/about/flashAbout_info_small.swf" quality="high" bgcolor="#FFFFFF" width="159" height="91" wmode="transparent" name="flashAbout_small" align="absmiddle" type="application/x-shockwave-flash" pluginspage="http://www.adobe.com/go/getflashplayer"/> </object> </span> </div> </body> </html> So clicking any colored shape should produce an alert (except for the green one in IE, not sure why but I hope that's off topic and not related to my issue). Clicking the Flash container in Firefox will work Perfectly fine. You should get alert boxes in this order containing: span, div and body. Flash bubbles the event to the HTML. But this is not happening in IE. So why is Flash in IE not bubbling events to HTML? Edit: As mentioned by Andy E this behavior can also bee seen in Google Chrome which to my knowledge is not using ActiveX to embed the flash movie into the page.

  • Plotting Scientific data in .net

    - by Dan Schubel
    Does anyone have any recommendations for plotting scientific data in .net (c# winforms). Some of my requirements are: real time plotting, 3D (waterfall), multiple axis, ability to accept BindingList as a data source and recognize any changes to the data. I also need a high level of user interactivity such as the ability to graphically select 1 or more series, draw regions. highlight part of a series, etc. So far I've looked at Nevron, Synchfusion, Infragistics, TeeChart and a few others.

  • How do I rename an R object?

    - by Milktrader
    I'm using the quantmod package to import financial series data from Yahoo. library(quantmod) getSymbols("^GSPC") [1] "GSPC" I'd like to change the name of object "GSPC" to "SPX". I've tried the rename function in the reshape package, but it only changes the variable names. The "GSPC" object has vectors GSPC.Open, GSPC.High, etc. I'd like my renaming of "GSPC" to "SPX" to also change GSPC.Open to SPX.Open and so on.

  • How do you set the sitemap priority for flatpages in django?

    - by mlissner
    I have a site with about 60,000 pages that are getting placed in the sitemap, and which have a priority of 0.3. These are all really long pages that are rich in keywords. I also have a few pages (like the about page), that need high priority, but which I've implemented with the django flatpages framework. Is it possible for pages created this way to have a higher priority in the sitemap?

  • JavaScript parser in JavaScript

    - by emk
    I need to add some lightweight syntactic sugar to JavaScript source code, and process it using a JavaScript-based build system. Are there any open source JavaScript parsers written in JavaScript? And are they reasonably fast when run on top of V8 or a similar high-performance JavaScript implementation? Thank you for any pointers you can provide!

  • database splitting; multiple tables

    - by Ben
    I am coding a classifieds ad web app. What is the optimal way to structure the database for this? Because of the high repeatability, would it be faster (in terms of searching/indexing) to have a separate table in the database for each city? Or would it be okay to just have one table for every city (it would have a lot of rows..). The classifieds table has id, user_id, city_name, category,[description and detail fields].

  • Single Instance Storage layers

    - by Moo
    Hi, I have a data storage requirement which is an excellent candidate for single instance storage and deduplication. Can anyone suggest any .Net compatible libraries or systems which handles SIS and deduplication, either with SQL Server as an actual back end or its own high performance storage engine? What have peoples experiences been with such engines, and are there any pit falls to watch out for? Regards Moo
