• Gmail Rolls Out New Compose Features

  - by Jason Fitzpatrick

  Gmail has several new features that make it even easier to compose email messages including pop-over compositions windows (similar to the Google Chat window), contact profile pictures in the address box, and drag and drop address switching. If you’ve ever had to open two separate windows in order to continually tab back and forth so you could reference one email while composing another, you’ll certainly appreciate the new pop-over compose window that allows you to work within Gmail while keeping a small email composition window open in the corner–as seen in the screenshot above. In addition to that major change, Gmail has also introduced contact photos in the address suggestion window (making it easier than ever to make sure you’re selecting the right recipient) and the ability to drag and drop addresses between the To:, CC:, and BCC: address slots.

• How To Smoothly Animate From One Camera Position To Another

  - by www.Sillitoy.com

  The Question is basically self explanatory. I have a scene with many cameras and I'd like to smoothly switch from one to another. I am not looking for a cross fade effect but more to a camera moving and rotating the view in order to reach the next camera point of view and so on. To this end I have tried the following code: firstCamera.transform.position.x = Mathf.Lerp(firstCamera.transform.position.x, nextCamer.transform.position.x,Time.deltaTime*smooth); firstCamera.transform.position.y = Mathf.Lerp(firstCamera.transform.position.y, nextCamera.transform.position.y,Time.deltaTime*smooth); firstCamera.transform.position.z = Mathf.Lerp(firstCamera.transform.position.z, nextCamera.transform.position.z,Time.deltaTime*smooth); firstCamera.transform.rotation.x = Mathf.Lerp(firstCamera.transform.rotation.x, nextCamera.transform.rotation.x,Time.deltaTime*smooth); firstCamera.transform.rotation.z = Mathf.Lerp(firstCamera.transform.rotation.z, nextCamera.transform.rotation.z,Time.deltaTime*smooth); firstCamera.transform.rotation.y = Mathf.Lerp(firstCamera.transform.rotation.y, nextCamera.transform.rotation.y,Time.deltaTime*smooth); But the result is actually not that good.

• Issues with ILMerge, Lambda Expressions and VS2010 merging?

  - by John Blumenauer

  A little Background For quite some time now, it’s been possible to merge multiple .NET assemblies into a single assembly using ILMerge in Visual Studio 2008.  This is especially helpful when writing wrapper assemblies for 3rd-party libraries where it’s desirable to minimize the number of assemblies for distribution.  During the merge process, ILMerge will take a set of assemblies and merge them into a single assembly.  The resulting assembly can be either an executable or a DLL and is identified as the primary assembly. Issue During a recent project, I discovered using ILMerge to merge assemblies containing lambda expressions in Visual Studio 2010 is resulting in invalid primary assemblies.  The code below is not where the initial issue was identified, I will merely use it to illustrate the problem at hand. In order to describe the issue, I created a console application and a class library for calculating a few math functions utilizing lambda expressions.  The code is available for download at the bottom of this blog entry. MathLib.cs using System; namespace MathLib { public static class MathHelpers { public static Func<double, double, double> Hypotenuse = (x, y) => Math.Sqrt(x * x + y * y); static readonly Func<int, int, bool> divisibleBy = (int a, int b) => a % b == 0; public static bool IsPrimeNumber(int x) { { for (int i = 2; i <= x / 2; i++) if (divisibleBy(x, i)) return false; return true; }; } } } Program.cs using System; using MathLib; namespace ILMergeLambdasConsole { class Program { static void Main(string[] args) { int n = 19; if (MathHelpers.IsPrimeNumber(n)) { Console.WriteLine(n + " is prime"); } else { Console.WriteLine(n + " is not prime"); } Console.ReadLine(); } } } Not surprisingly, the preceding code compiles, builds and executes without error prior to running the ILMerge tool.   ILMerge Setup In order to utilize ILMerge, the following changes were made to the project. The MathLib.dll assembly was built in release configuration and copied to the MathLib folder.  The following folder hierarchy was used for this example:   The project file for ILMergeLambdasConsole project file was edited to add the ILMerge post-build configuration.  The following lines were added near the bottom of the project file:  <Target Name="AfterBuild" Condition="'$(Configuration)' == 'Release'"> <Exec Command="&quot;..\..\lib\ILMerge\Ilmerge.exe&quot; /ndebug /out:@(MainAssembly) &quot;@(IntermediateAssembly)&quot; @(ReferenceCopyLocalPaths->'&quot;%(FullPath)&quot;', ' ')" /> <Delete Files="@(ReferenceCopyLocalPaths->'$(OutDir)%(DestinationSubDirectory)%(Filename)%(Extension)')" /> </Target> The ILMergeLambdasConsole project was modified to reference the MathLib.dll located in the MathLib folder above. ILMerge and ILMerge.exe.config was copied into the ILMerge folder shown above.  The contents of ILMerge.exe.config are: <?xml version="1.0" encoding="utf-8" ?> <configuration> <startup useLegacyV2RuntimeActivationPolicy="true"> <requiredRuntime safemode="true" imageVersion="v4.0.30319" version="v4.0.30319"/> </startup> </configuration> Post-ILMerge After compiling and building, the MathLib.dll assembly will be merged into the ILMergeLambdasConsole executable.  Unfortunately, executing ILMergeLambdasConsole.exe now results in a crash.  The ILMerge documentation recommends using PEVerify.exe to validate assemblies after merging.  Executing PEVerify.exe against the ILMergeLambdasConsole.exe assembly results in the following error:    Further investigation by using Reflector reveals the divisibleBy method in the MathHelpers class looks a bit questionable after the merge.     Prior to using ILMerge, the same divisibleBy method appeared as the following in Reflector: It’s pretty obvious something has gone awry during the merge process.  However, this is only occurring when building within the Visual Studio 2010 environment.  The same code and configuration built within Visual Studio 2008 executes fine.  I’m still investigating the issue.  If anyone has already experienced this situation and solved it, I would love to hear from you.  However, as of right now, it looks like something has gone terribly wrong when executing ILMerge against assemblies containing Lambdas in Visual Studio 2010.

• How to handle mutiple API calls using javascript/jquery

  - by James Privett

  I need to build a service that will call multiple API's at the same time and then output the results on the page (Think of how a price comparison site works for example). The idea being that as each API call completes the results are sent to the browser immediately and the page would get progressively bigger until all process are complete. Because these API calls may take several seconds each to return I would like to do this via javascript/jquery in order to create a better user experience. I have never done anything like this before using javascript/jquery so I was wondering if there was any frameworks/advice that anyone would be willing to share.

• Java Alphabetize Algorithm Insertion sort vs Bubble Sort

  - by Chris Okyen

  I am supposed to "Develop a program that alphabetizes three strings. The program should allow the user to enter the three strings, and then display the strings in alphabetical order." It's instructed that I need to use the String library compareTo()/charAt()/toLowerCase() to make all the characters lowercase so the Lexicon comparison is also a alphabetical comparison. Input Pseudo Code: String input[3]; Scanner keyboard = new Scanner(System.in); System.out.println("Enter three strings: "); for(byte i = 0; i < 3; i++) input[i] = keyboard.next() The sorting would be Insertion Sort: 321 2 3 1 2 31 231 1 23 1 2 3 1 23 1 23 123 Bubble Sort 321 231 213 123 Which would be more efficient in this case? The bubble sort seems to be more efficient though they seem to have equal stats for worst best and avg case, but I read the Insertion Sort is quicker for small amounts of data like my case.

• Problem with audio sharing between different programs

  - by Lars Borg

  I've been using Linux for quite some time, but until now I've never run into any problems. I also saw the thread "Sound, stopping between multiple programs", but it is referring to a very old version... My problem is that when I run Diablo 3 (using PlayOnLinux) and Skype 4 at the same time, I only get audio from the program that I start first. If I start skype first and then Diablo 3, I have perfekt audio in Skype and sometimes I might hear a faint whisper of the Diablo sounds... This problem started after I changed motherboard to Asus p8z77-v pro with 16GB memory and Intel i7 3770K CPU. With the old motherboard, all this worked just fine. The OS is Ubuntu 12.04. I have only installed Wine, PlayOnLinux, Skype 4, and Diablo 3. All of the latest version, as far as I know. What should I do? What do you need to know, in order to be able to help? Thanks /Lasse

• What's the best Wireframing tool?

  - by Strae

  I'm looking for something similar to iPlotz or Mockup. I've found the Pencil Project, but it requires xulrunner-1.9 (which seems to be incompatible with xulrunner-1.9.2) in order to run as a standalone application. It can be used as a firefox plugin... but it is a bit slower. The error on my desktop (Ubuntu 10.04) is: Could not find compatible GRE between version 1.9.1 and 1.9.2.* Does anyone know other software? Edit: Open-source software is preferred, and it doesn't matter whether or not it's free.

• Using Windows Previous Versions to access ZFS Snapshots (July 14, 2009)

  - by user12612012

  The Previous Versions tab on the Windows desktop provides a straightforward, intuitive way for users to view or recover files from ZFS snapshots.  ZFS snapshots are read-only, point-in-time instances of a ZFS dataset, based on the same copy-on-write transactional model used throughout ZFS.  ZFS snapshots can be used to recover deleted files or previous versions of files and they are space efficient because unchanged data is shared between the file system and its snapshots.  Snapshots are available locally via the .zfs/snapshot directory and remotely via Previous Versions on the Windows desktop. Shadow Copies for Shared Folders was introduced with Windows Server 2003 but subsequently renamed to Previous Versions with the release of Windows Vista and Windows Server 2008.  Windows shadow copies, or snapshots, are based on the Volume Snapshot Service (VSS) and, as the [Shared Folders part of the] name implies, are accessible to clients via SMB shares, which is good news when using the Solaris CIFS Service.  And the nice thing is that no additional configuration is required - it "just works". On Windows clients, snapshots are accessible via the Previous Versions tab in Windows Explorer using the Shadow Copy client, which is available by default on Windows XP SP2 and later.  For Windows 2000 and pre-SP2 Windows XP, the client software is available for download from Microsoft: Shadow Copies for Shared Folders Client. Assuming that we already have a shared ZFS dataset, we can create ZFS snapshots and view them from a Windows client. zfs snapshot tank/home/administrator@snap101zfs snapshot tank/home/administrator@snap102 To view the snapshots on Windows, map the dataset on the client then right click on a folder or file and select Previous Versions.  Note that Windows will only display previous versions of objects that differ from the originals.  So you may have to modify files after creating a snapshot in order to see previous versions of those files. The screenshot above shows various snapshots in the Previous Versions window, created at different times.  On the left panel, the .zfs folder is visible, illustrating that this is a ZFS share.  The .zfs setting can be toggled as desired, it makes no difference when using previous versions.  To make the .zfs folder visible: zfs set snapdir=visible tank/home/administrator To hide the .zfs folder: zfs set snapdir=hidden tank/home/administrator The following screenshot shows the Previous Versions panel when a file has been selected.  In this case the user is prompted to view, copy or restore the file from one of the available snapshots. As can be seen from the screenshots above, the Previous Versions window doesn't display snapshot names: snapshots are listed by snapshot creation time, sorted in time order from most recent to oldest.  There's nothing we can do about this, it's the way that the interface works.  Perhaps one point of note, to avoid confusion, is that the ZFS snapshot creation time isnot the same as the root directory creation timestamp. In ZFS, all object attributes in the original dataset are preserved when a snapshot is taken, including the creation time of the root directory.  Thus the root directory creation timestamp is the time that the directory was created in the original dataset. # ls -d% all /home/administrator         timestamp: atime         Mar 19 15:40:23 2009         timestamp: ctime         Mar 19 15:40:58 2009         timestamp: mtime         Mar 19 15:40:58 2009         timestamp: crtime         Mar 19 15:18:34 2009 # ls -d% all /home/administrator/.zfs/snapshot/snap101         timestamp: atime         Mar 19 15:40:23 2009         timestamp: ctime         Mar 19 15:40:58 2009         timestamp: mtime         Mar 19 15:40:58 2009         timestamp: crtime         Mar 19 15:18:34 2009 The snapshot creation time can be obtained using the zfs command as shown below. # zfs get all tank/home/administrator@snap101NAME                             PROPERTY  VALUEtank/home/administrator@snap101  type      snapshottank/home/administrator@snap101  creation  Mon Mar 23 18:21 2009 In this example, the dataset was created on March 19th and the snapshot was created on March 23rd. In conclusion, Shadow Copies for Shared Folders provides a straightforward way for users to view or recover files from ZFS snapshots.  The Windows desktop provides an easy to use, intuitive GUI and no configuration is required to use or access previous versions of files or folders.

• Moving camera, or camera with discrete "screens"?

  - by Jacob Millward

  I'm making a game with a friend, but having trouble deciding on a camera style. The basic idea for the game, is having a randomly generated 2-dimensional world, with settlements in it. These settlements would have access to different resources, and it would be the job of the player to create bridges and ladders and links between these villages so they can trade. The player would advance personally by getting better gear, fighting monsters and looking for materials in the world, in order to craft and trade them at the settlements. My friend wants to use an old-style camera, where the world is split into a discrete number of screens that the player moves between. Similar to early Zelda dungeons, or Knytt Stories. This is opposite to me, as I want a standard camera that follows the player around as I feel the split-screen style camera limits the game. Can anyone argue the case either way? We've hit a massive roadblock here and can't seem to get past it.

• What simple techniques do you use to improve performance?

  - by Cristian

  I'm talking about the way we write simple routines in order to improve performance without making your code harder to read... for instance, this is the typical for we learned: for(int i = 0; i < collection.length(); i++ ){ // stuff here } But, I usually do this when a foreach is not applicable: for(int i = 0, j = collection.length(); i < j; i++ ){ // stuff here } I think this is a better approach since it will call the length method once only... my girlfriend says it's cryptic though. Is there any other simple trick you use on your own developments?

• How to clone a VirtualBox Disk

  - by [email protected]

   How to clone a VirtualBox DiskCopying the image of Virtual Disk (.vdi file) is a convenient way to duplicate the disk, in cases you want to avoid re-installing an operating system from scratch. However, simply copying the .vdi file into another location will make a verbatim copy of the virtual disk, including the UUID of the disk. If you try to add the copy in the Virtual Media Manager, you will get an error like this:In this case, you have to do is to clone the vdi disk: cd C:\Program Files\Sun\VirtualBox\C:\Program Files\Sun\VirtualBox>vboxmanage clonevdi G:\VMWARES\Database\11GR2onOEL5forVbox\11GR2_OEL5_32GB.vdi G:\VMWARES\Database\11GR2onOEL5forVbox\OEL5_32GB.vdi$ VBoxManage clonevdi Master.vdi Clone.vdiIn case you receive a error like this. It means that the disk is already a copy of other VirtualBox Disk.In that case you chould change the UUID before to clone the Disk.Follow the steps given here in order to do that.

• google analytics reverse transaction not working with sales performance

  - by prasad maganti

  We have google analytics account and trying to do reverse transaction. We have created a transaction on one date and reverse transaction on some other date. After transaction if we do reverse transaction it disappears from transactions list. Is it the expected behavior or abnormal behavior? But, if we check the same order data in sales performance, the reverse transaction does not reflects on when we created the transaction, it reflecting on when we made reverse transaction date. It should not be do like this. The reverse transaction should affect the same date on when we made transaction date.

• Opening images sorted by modification date/size/type/etc

  - by menino bolinho

  Suppose I have a folder with pictures in them. If I sort them by name once I open one with Image Viewer and navigate to the others the order is respected. But if I sort my files by modification date, for example, I can't do that. Basically, the default Image Viewer only lets you navigate images by name. According to this post on the ubuntuforums this has been an issue since 2007! Is there a good/easy way to fix it? Seems like such a trivial thing to me.

• HTML Canvas: Should my app x, y values be global?

  - by Joe

  I have a large file of functions. Each of these functions is responsible for drawing a particular part of the application. My app has x and y parameters that I use in the setup function to move the whole app around in order to try different placements. So, naturally, I need to use these x and y values to anchor each function's component rendering so that everything moves in unison if the global x,y values ever change. My question is, is it bad practice/architecture to have these x,y values in the global namespace and having the each function directly access them like so? function renderFace() { var x = App.x; var y = App.y; // drawing here } is there a better way i'm missing?

• Silverlight Html Placeholder now support OOB mode

  With the official Silverlight 4 release this week, one of the things we introduced in the Telerik Silverlight controls is the ability to use the Html Placeholder control in OOB in the same way you do when the control is hosted in the browser. The good news is that you don't need to do anything in order to enable this feature. It comes out of the box and if you have an app that is using the HtmlPlaceholder you just need to install it in OOB mode to see the same html that you are seeing when the application is hosted in the browser. When in OOB mode we are using internally the Microsoft WebBrowser control to render the Html - that's why this feature is SL4 specific and is not available in the SL3 binaries (which we still officially support).   Go play with it and if you have any questions ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Custom code in SharePoint

  - by Sahil Malik

  SharePoint 2010 Training: more information Microsoft launched SharePoint 2013 with great fanfare. But what stuck out was the introductory blog post by Corporate SVP of SharePoint, Jeff Teper. You can read the blogpost titled “The New SharePoint”. But one paragraph has stuck out, “Use SharePoint as an out-of-box application whenever possible - We designed the new SharePoint UI to be clean, simple and fast and work great out-of-box. We encourage you not to modify it which could add complexity, performance and upgradeability and to focus your energy on working with users and groups to understand how to use SharePoint to improve productivity and collaboration and identifying and promoting best practices in your organization.” The keywords here is “whenever possible”. The reality is, frequently it is not possible to not customize SharePoint in order to meet the customer requirements. But you must try and minimize SharePoint customization.

• Manual bootstrapping with Juju on VPS

  - by aaronfc

  I recently bought a VPS (OpenVZ) with Ubuntu 13.04. Lately I've read about Juju and I thought it would match my needs on my brand new VPS as I want to easily configure Hadoop, Wordpress, Graphite and other services. I tried the juju-local approach but I got an error while installing it: http://paste.ubuntu.com/6373143/ So I got to #juju IRC channel and I was told to use "Manual bootstrapping" and create a question here in order to get more info as it seems is something under development. Could anybody help me getting Juju to work on my VPS? Did any had the same problem? Thanks in advance! EDIT: After some more research (and after reading my own question) I think I should clarify a little more the situation. What I want is a manual provider to allow me manage my VPS from Juju. I know there might be a work in progress and I would appreciate any info regarding it's state and any possible solution :)

• Do you know that every user story should have an owner?

  - by Martin Hinshelwood

  When you are building complicated software and working with customers it is always nice for them to have some idea on who to speak to about a particular story during a sprint. In order to achieve this one of the Team takes responsibility for “looking after” a story. They will collect all of the “Done” emails and make sure that everyone follows the Done criteria identified by the team as well as answering any Product Owner queries. Figure: Bad example, The product owner is not sure who to speak to. Figure: Good example, The product owner can now see who he should speak to an developers know where to send done emails.   Technorati Tags: SSW,Scrum,SSW Rules,Rules to better Scrum with TFS

• Where should i organize my matrices in a 3D Game engine?

  - by Need4Sleep

  I'm working with a group of people from around the world to create a game engine(and hopefully a game with it) within the next upcoming years. My first task was writing a camera class for the engine to use in order to add cameras to the scene, position and follow points in the scene. The problem i have is with using matrices for transformations in the class, should i keep matrices separate to each class? such as have the model matrix in the model class, camera matrix in the camera class, or have all matrices placed in one class/chuck? I could see pros and cons for each method, but i wanted to hear some input form a more professional standpoint.

• Paying a developer in stock/fixed rate? [closed]

  - by user51648

  I have an idea for a cross platform application. It will require knowledge of several different languages, web development, and system administration/IT. I don't personally code, but I want to pay professionals to do it. I'm wondering how I should go about paying them. Yes, this will be a large project, but I want it done ASAP. Is it ok if I don't pay them by the hour? I really want it to be a set price. Also, is it reasonable to pay them in stock of the company? Like, 20%? P.S. How do I know how big a project will be in order to give the devs themselves an idea?
