  • Ubuntu 12.10 - launcher stays hidden

    - by Mieszko
    Just upgraded to 12.10 today. Everything seems fine for now, aprat from one thing: The launcher on the left side of the screen doesn't come up after moving the cursor to the left side of the screen. It IS there since it show the app start animation and I can have it on top all the time, but I'm really fond of it being hidden most of the time. I did check the sensitivity settings and even set it up to MAX (thus high) and it changes nothing. Please help ;) Cheers

  • Large Sprite Performance

    - by Iansen
    I've got a large Sprite generated using a set of vertices(x,y coordinates) and a bitmap pattern (using moveTo, lineTo, beginBitmapFill, endFill ...etc). It's about 15000 pixels wide and between 1500 - 2000 pixels high depending on the level -it's the terrain for a 2D game. My question is: what is the best way to display/move it on the stage - performance wise? Currently I'm just adding it to the stage as is...I get decent frame rate/ memory/ cpu usage but I want to optimize it for slower PCs. Any ideas? I've been reading a little about blitting but I'm not sure how to implement it in my case. Thanks.

  • SPException: Catastrophic failure (Exception from HRESULT: 0x8000FFF (E_UNEXPECTED) in Sharepoint

    - by BeraCim
    I've been trying to programmatically copy custom content type and its custom columns from one web to another for some time now, and I always get different errors or exceptions every time. After yet more tries, I received more strange and cryptic exception from Sharepoint after clicking onto a newly copied custom column in a custom content type. I checked the logs, and this is what I got: Unknown SPRequest erorr occurred. More information: 0x80070002 Unable to locate the xml-definition for FieldName with FieldId 'guid without braces', exception: Microsoft.SharePoint.SPException: Catastrophic failure (Exception from HRESULT: 0x8000FFF (E_UNEXPECTED)) ---> System.Runtime.InteropServices.COMException... ... at Microsoft.SharePoint.Library.SPRequestInternalClass.GetGlobalContentTypeXml(String bstrUrl, Int32 type, UInt 32 lcid, Object varIdBytes...

I'm confused with what Sharepoint is trying to do here, and why a simple process of copying a custom content type from one web to another just wouldn't work in contrast to the information found on the web e.g. this. Appreciate any help to get over this problem. Thanks.

  • MvvmLight EventToCommand and WPFToolkit DataGrid double-click

    - by Tom
    Trying to figure out how to use EventToCommand to set a datagrid double click handler for rows. The command lives in the viewmodel for each row. Just that much out of my experience, since I haven't used interactions yet. Thanks. I would have used mvvmlight tag, but I don't have high enough rep yet to make new tags.

  • Alternative to Amazon’s S3 service?

    - by Cory
    Just wondering if there is good alternative to Amazon's S3 service? I like S3 but the bandwidth cost is high. I looked at CouldFiles from Rackspace but the cost is even higher. I don't mind prepaying or having monthly payment in order to reduce the bandwidth cost greatly. Thank you for any help

    I am making a WPF Application in C# where I need to show the recent documents history (just like it happens in word, excel and even visual studio), showing the list the last 5 or 10 documents opened. I have absolutely no idea as to how I should go about it. Please help. And please be kind and gentle...I am an amatuer coder, and it is tough to digest high-tech talks as of now! :)

  • Kanban vs. Scrum

    - by Andrew Siemer
    Can someone with Kanban experience tell me how Kanban and Scrum differ? What are the pro's and con's of each of the different project management methodologies? Kanban seems to be getting a lot of press these days. I don't want to miss the hottest new way of tracking my teams failures (...and successes). Responses @S. Lott - What part of this article wasn't clear enough? infoq.com/articles/hiranabe-lean-agile-kanban/…. Do you have a more specific question? That is a great article but technically no it is not clear enough. That article gives a great amount of detail about kanban (and thank you for it...good read) but it does not specifically contrast Kanban vs. Scrum. That article will help someone like me make a decision but it most certainly won't help someone like my boss or in general someone less experienced! I was hoping for a quick overview of kanban pros and cons contrasted to scrum pros and cons. Thanks though! @S. Lott - Why do you say kanban vs. scrum? What leads you to conclude they are conflicting approaches? Can you make your question more specific? I don't think that they are necessarily conflicting. But they are different enough for a user to adhere to one over the other. Perhaps one fits a project or company better than the other? How would I sell one over the other when presenting a project management approach. Say I went to a company that was currently stuck in the rutt that is "water fall" - why would I sell one approach over the other?

  • Creating content of window programmatically

    - by Rui Pacheco
    Hi, I've a window that will have an unknown amount of text fields, determined by the content of a remote server. In high level terms, how should I go about this? Create a custom view or create an empty window with a backing NSWindowController and then add stuff to it when the window is opened? I've seen the examples on the O'Reilly Cocoa book and those effectively create a custom NSView. Is this the right way to do it, 8 year later?

  • which metric(s) show the difference between object-oriented and procedural code

    - by twieger
    Which metric(s) could help to indicate that i have procedural code instead of object-oriented code? I would like to have a set of simple metrics, which indicate with a high probability, that the analyzed code contains procedural transaction scripts and an anemic domain model instead of following sound object-oriented design principles. Would be happy about any set of useful metrics and tools for measuring. Thanks, Thomas!

    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

    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?

  • 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?

  • 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.

  • Creating a Custom Design-Time Environment

    - by Charlie
    Hello all, My question is related to the design-time support of WPF. From MSDN I read, The WPF Designer provides a framework and a public API which you can use to implement custom adorners, tools, property editors, and designers. But the vast majority of the examples I have found are trivial, and do not illustrate much concerning the creation of a customized designer in an existing WPF application. We have migrated our application from Windows Forms to WPF over the past year, and the next step will be to take an existing WinForms Panel designer, and rewrite it in WPF. Suffice it to say that this will be a huge project. But I don't even know where to begin. I am wondering if any of you have had similar experiences writing a customized designer for a WPF application, and what it was like. Even better, if you could compare and contrast the functionality between the WinForms designer and the WPF designer, or explain the transition from the former to the latter, that would be helpful. If you know of any simple examples that demonstrate a customized design environment (with custom controls, etc.) that would be extremely beneficial. All in all, I am just wondering if many people have undertaken this yet, and what their results have been. EDIT: To clarify, yes, I am talking about hosting a WPF designer. It appears that this may not even be possible, which is a huge setback. Here is a screenshot of our current WinForms designer. As you can see, it is used to create customized user interfaces. You can drag custom controls onto it and design them, then put the panel into a "run mode" in which all of the controls become functional. Short of spending months writing our designer, would this be possible in WPF? What about .NET 4.0 and VS2010? Will those add any designer functionality?

  • 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.
