• Scripted SOA Diagnostic Dumps for PS6 (11.1.1.7)

  - by ShawnBailey

  When you upgrade to SOA Suite PS6 (11.1.1.7) you acquire a new set of Diagnostic Dumps in addition to what was available in PS5. With more than a dozen to choose from and not wanting to run them one at a time, this blog post provides a sample script to collect them all quickly and hopefully easily. There are several ways that this collection could be scripted and this is just one example. What is Included: wlst.properties: Ant Properties build.xml soa_diagnostic_script.py: Python Script What is Collected: 5 contextual thread dumps at 5 second intervals Diagnostic log entries from the server WLS Image which includes the domain configuration and WLS runtime data Most of the SOA Diagnostic Dumps including those for BPEL runtime, Adapters and composite information from MDS Instructions: Download the package and extract it to a location of your choosing Update the properties file 'wlst.properties' to match your environment Run 'ant' (must be on the path) Collect the zip package containing the files (by default it will be in the script.output location) Properties Reference: oracle_common.common.bin: Location of oracle_common/common/bin script.home: Location where you extracted the script and supporting files script.output: Location where you want the collections written username: User name for server connection pwd: Password to connect to the server url: T3 URL for server connection, '<host>:<port>' dump_interval: Interval in seconds between thread dumps log_interval: Duration in minutes that you want to go back for diagnostic log information Script Package

• ECS with Go - circular imports [migrated]

  - by Andreas

  I'm exploring both Go and Entity-Component-Systems. I understand how ECS works, and I'm trying to replicate what seems to be the go-to document of ECS, namely http://cowboyprogramming.com/2007/01/05/evolve-your-heirachy/ For performance, the document recommends to use static arrays of every component type. That is, not arrays of component interfaces (arrays of pointers). The problem with this in Go is circular imports. I have one package, ecs, which contains the definitions for Entity, Component and System types/interfaces as well as an EntityManager. Another package, ecs/components, contains the various components. Obviously, the ecs/components package depends on ecs. But, to declare arrays of specific components in EntityManager, ecs would depend on ecs/components, therefore creating a circular import. Is there any way of avoiding this? I am aware that normally a high level system should not depend on lower systems. I'm also want to point out that using an array of pointers is probably fast enough for my purposes, but I'm interested in possible workarounds (for future reference) Thank you for your help!

• Emacs stops taking input when a file has changed on disk [migrated]

  - by recf

  I'm using Emacs v24.3.1 on Windows 8. I had a file change on disk while I had an Emacs buffer open with that file. As soon as I attempt to make a change to the buffer, a message appears in the minibuffer. Fileblah.txt changed on disk; really edit the buffer? (y, n, r or C-h) I would expect to be able to hit r to have it reload the disk version of the file, but nothing happens. Emacs completely stops responding to input. None of the listed keys work, nor do any other keys as far as I can tell. I can't C-g out of the minibuffer. Alt-F4 doesn't work, not does Close window from the task bar. I have to kill the process from task manager. Anyone have any idea what I'm doing wrong here? In cases it's various modes not playing nice with each other, for reference, my init.el is here. Nothing complex. Here's the breakdown: better-defaults (ido-mode, remove menu-bar, uniquify buffer `forward, saveplace) recentf-mode custom frame title visual-line-mode require final newline and delete trailing whitespace on save Markdown mode with auto-mode-alist Flyspell with Aspell backend Powershell mode with auto-mode-alist Ruby auto-mode-alist Puppet mode with auto-mode-alist Feature (Gherkin) mode with auto-mode-alist The specific file was a markdown file with Github-flavored Markdown mode and Flyspell mode enabled.

• What are the memory-management capabilities of MySQL + JDBC (in light of autonomic computing)?

  - by Adel

  I'm interested in implementing some kind of autonomic-computing functionality using MySQL. By autonomic-computing I mean roughly some failsafe abilities, whereby the application appears to be at least slightly "intelligent" For reference, the main parts of autonomic computing we'd like are the "self-configuring" and "self-healing" features (the other two - "self-optimizing" and "self-protecting", are too abstract/futuristic for us, at this time). Sofor example, if we have a sample Java application that utilizes a MySQL database, we might want to automatically restart the MySQL database if we take up too much memory. Or maybe we want to have the ability to dynamiccally adjust the database memory as needed. So for example, when we start the application the database begins with a 56 Megabyte buffer; but then as we insert so many rows we want to have it automatically jump up to 512 MB, then to 1024, until a max of 4096 MB. Does all of the above suggest that MySQL is too "weak" for the task? Do you suggest using Oracle database? My professor believes that by using Java we can basically make up for any memory-management deficiencies that MySQL has in relation to Oracle DB. I'm new to MySQL , but have experience with Oracle. If all of the above sounds wishy-washy, it is because I'm still fleshing it out. thanks

• LDoms with Solaris 11

  - by Orgad Kimchi

  Oracle VM Server for SPARC (LDoms) release 2.2 came out on May 24. You can get the software, see the release notes, reference manual, and admin guide here on the Oracle VM for SPARC page. Oracle VM Server for SPARC enables you to create multiple virtual systems on a single physical system.Each virtual system is called alogical domain and runs its own instance of Oracle Solaris 10 or Oracle Solaris 11. The version of the Oracle Solaris OS software that runs on a guest domain is independent of the Oracle Solaris OS version that runs on the primary domain. So, if you run the Oracle Solaris 10 OS in the primary domain, you can still run the Oracle Solaris 11 OS in a guest domain, and if you run the Oracle Solaris 11 OS in the primary domain, you can still run the Oracle Solaris 10 OS in a guest domain In addition to that starting with the Oracle VM Server for SPARC 2.2 release you can migrate guest domain even if source and target machines have different processor type. You can migrate guest domain from a system with UltraSPARC  T2+ or SPARC T3 CPU to a system with a SPARC T4 CPU.The guest domain on the source and target system must run Solaris 11 In order to enable cross CPU migration.In addition to that you need to change the cpu-arch property value on the source system. For more information about Oracle VM Server for SPARC (LDoms) with Solaris 11 and  Cross CPU Migration refer to the following white paper

• Booting off a ZFS root in 14.04

  - by RJVB

  I've been running a Debian derivative (LMDE) on a ZFS root for half a year now. It was created by cloning a regular ext4-based install with all the necessary packages onto a ZFS pool, chrooting into that pool and recreating a grub menu and bootloader. The system uses an ext-3 dedicated /boot partition. I would like to do the same with Ubuntu 14.04, but have encountered several obstacles. There is no Trusty zfs-grub package The default grub package doesn't have ZFS support built in. I found a small bug in the build system responsible for that (report with patch created) and built my own grub packages. The built-in ZFS support is dysfunctional, it does not add the proper arguments to the kernel command line I thus installed the ZoL grub package I also use on my LMDE system, which does give me a correct grub.cfg However, even with that correct grub.cfg, the boot process apparently doesn't retrieve the bootfs parameter from the ZFS pool; instead the variable that's supposed to receive the value remains empty. As a result, initrd tries to load the default pool ("rpool"), which fails of course. I can however import the pool by hand, and complete the process by hand. If memory serves me well, I also had to disable apparmor, to avoid the boot process from blocking after importing the pool. Am I overlooking something? Just for comparison, I installed the Ubuntu 3.13 kernel on my LMDE system, and that works just fine (i.e. the identical kernel and grub binaries allow successful booting without glitches on LMDE but not on Ubuntu).

• Query for server DefaultData & DefaultLog folders

  - by jamiet

  Do you ever need to query for the DefaultData & DefaultLog folders for your SQL Server instance? Well, I just did and the following script enabled me to do that: DECLARE @HkeyLocal NVARCHAR(18),@MSSqlServerRegPath NVARCHAR(31),@InstanceRegPath SYSNAME; SELECT @HkeyLocal=N'HKEY_LOCAL_MACHINE' SELECT @MSSqlServerRegPath=N'SOFTWARE\Microsoft\MSSQLServer' SELECT @InstanceRegPath=@MSSqlServerRegPath + N'\MSSQLServer' DECLARE @SmoDefaultFile NVARCHAR(512) EXEC MASTER.dbo.xp_instance_regread @HkeyLocal, @InstanceRegPath, N'DefaultData', @SmoDefaultFile OUTPUT DECLARE @SmoDefaultLog NVARCHAR(512) EXEC MASTER.dbo.xp_instance_regread @HkeyLocal, @InstanceRegPath, N'DefaultLog', @SmoDefaultLog OUTPUT SELECT ISNULL(@SmoDefaultFile,N'') AS [DefaultFile],ISNULL(@SmoDefaultLog,N'') AS [DefaultLog]' I haven’t done any rigorous testing or anything like that, all I can say is…it worked for me (on SQL Server 2012). Use as you see fit. Doubtless this information exists in a multitude of other places but nevertheless I’m putting it here so I know where to find it in the future. Just for fun I thought I’d try this out against SQL Azure Windows Azure SQL Database. Unsurprisingly it didn’t work there: Msg 40515, Level 15, State 1, Line 16 Reference to database and/or server name in 'MASTER.dbo.xp_instance_regread' is not supported in this version of SQL Server. @Jamiet

• Input of mouseclick not always registered in XNA Update method

  - by LordrAider

  I have a problem that not all inputs of my mouse events seem to be registered. The update logic is checking a 2 dimensional array of 10x10 . It's logic for a jewel matching game. So when i switch my jewel I can't click on another jewel for like half a second. I tested it with a click counter variable and it doesn't hit the debugger when i click the second time after the jewel switch. Only if I do the second click after waiting half a second longer. Could it be that the update logic is too heavy that while he is executing update logic my click is happening and he doesn't register it? What am I not seeing here :)? Or doing wrong. It is my first game. My function of the update methode looks like this. public void UpdateBoard() { MouseState currentMouseState; currentMouseState = Mouse.GetState(); if (currentMouseState.LeftButton == ButtonState.Pressed && prevMouseState.LeftButton != ButtonState.Pressed) { UpdatingLogic = true; // this.CheckDropJewels(currentMouseState); //this.CheckMatches(3); //this.RemoveMatches(); this.CheckForSwitch(currentMouseState); this.MarkJewel(currentMouseState); UpdatingLogic = false; //reIndexMissingJewels = true; reIndexSwitchedJewels = true; } prevMouseState = currentMouseState; this.ReIndex(); this.UpdateJewels(); }

• How should I group these variables?

  - by stariz77

  I have a shape that will be defined by: char s_type; char color; double height; double width; These variables are scanned in from a request string sent to my server and passed into my printing function, which then prints out the shape. Currently they are just local variables sitting in my main(); however, I was wondering if there would be any advantage in creating a struct containing these variables, and then passing the struct to my printing function? or how else might I improve my program's structure/style, would passing a struct by reference have any kind of performance benefit if there were many requests and therefore many printing function calls? printer(char st, char cr, double ht, double wd); int main() { // Other main functionality. char s_type; char color; double height; double width; sscanf (serv_req, "GET /%c/%c/%lf/%lf", &s_type, &color, &height, &width); printer(s_type, color, height, width); // Other main functionality. return 0; } It seemed "neater" if I had a struct or something that didn't leave me with declarations in the middle of everything else going on in main. I'm interested in structure/style as well as performance. EDIT: didn't mean to put printer declaration inside main.

• What’s ‘default’ for?

  - by Strenium

  Sometimes there's a need to communicate explicitly that value variable is yet to be "initialized" or in other words - we’ve never changed it from its' default value. Perhaps "initialized" is not the right word since a value type will always have some sort of value (even a nullable one) but it's just that - how do we tell? Of course an 'int' would be 0, an 'enum' would the first defined value of a given enum and so on – we sure can make this kind of check "by hand" but eventually it would get a bit messy. There's a more elegant way with a use of little-known functionality of: 'default'Let’s just say we have a simple Enum: Simple Enum namespace xxx.Common.Domain{    public enum SimpleEnum    {        White = 1,         Black = 2,         Red = 3    }}   In case below we set the value of the enum to ‘White’ which happens to be a first and therefore default value for the enum. So the snippet below will set value of the ‘isDefault’ Boolean to ‘true’. 'True' Case SimpleEnum simpleEnum = SimpleEnum.White;bool isDefault; /* btw this one is 'false' by default */ isDefault = simpleEnum == default(SimpleEnum) ? true : false; /* default value 'white' */   Here we set the value to ‘Red’ and ‘default’ will tell us whether or not this the default value for this enum type. In this case: ‘false’. 'False' Case simpleEnum = SimpleEnum.Red; /* change from default */isDefault = simpleEnum == default(SimpleEnum) ? true : false; /* value is not default any longer */ Same 'default' functionality can also be applied to DateTimes, value types and other custom types as well. Sweet ‘n Short. Happy Coding!

• Encapsulating code in F# (Part 2)

  - by MarkPearl

  In part one of this series I showed an example of encapsulation within a local definition. This is useful to know so that you are aware of the scope of value holders etc. but what I am more interested in is encapsulation with regards to generating useful F# code libraries in .Net, this is done by using Namespaces and Modules. Lets have a look at some C# code first… using System; namespace EncapsulationNS { public class EncapsulationCLS { public static void TestMethod() { Console.WriteLine("Hello"); } } } Pretty simple stuff… now the F# equivalent…. namespace EncapsulationNS module EncapsulationMDL = let TestFunction = System.Console.WriteLine("Hello") ()   Even easier… lets look at some specifics about F# namespaces… Namespaces are open. meaning you can have multiple source files and assemblies can contribute to the same namespace. So, Namespaces are a great way to group modules together, so the question needs to be asked, what role do modules play. For me, the F# module is in many ways similar to the vb6 days of modules. In vb6 modules were separate files and simply allowed us to group certain methods together. I find it easier to visualize F# modules this way than to compare them to the C# classes. However that being said one is not restricted to one module per file – there is flexibility to have multiple modules in one code file however with my limited F# experience I would still recommend using the file as the standard level of separating modules as it is very easy to then find your way around a solution. An important note about interop with F# and other .Net languages. I wrote a blog post a while back about a very basic F# to C# interop. If I were to reference an F# library in a C# project (for instance ‘TestFunction’), in C# it would show this method as a static method call, meaning I would not have to instantiate an instance of the module.

• Designing communications for extensibility

  - by Thomas S.

  I am working on the design stages of an application that will a) collect data from various sources (in my case that's scientific data from serial ports), keeping track of the age of the data, b) generate real-time statistics (e.g. running averages) c) display, record, and otherwise handle the data (and statistics). I anticipate that I will be adding both data producers and consumers over time, and would like to design this application abstractly so that I will be able to trivially add functionality with a small amount of interface code. What I'm stumbling on is deciding what communication infrastructure I should use to handle the interfaces. In particular, how should I make the processed data and statistics available to multiple consumers? Some things I've considered: Writing to several named pipes (variable number). Each consumer reads from one of them. Using FUSE to make a userspace filesystem where a read() returns the latest line of data even if another process has already read it. Making a TCP server, and having consumers connect and request data individually. Simply writing the consumers as part of the same program that aggregates the data. So I would like to hear your all's advice on deciding how to interface these functions in the best way to keep them separate and allow room for extenstions.

• Spring Cleaning

  - by Tim Dexter

  I recently got a shiny new laptop; moving my shiz from old to new, was not the nightmare it used to be. I have gotten into the habit of using a second hard drive in the media bay where the CDROM normally sits. That drive contains my life's work with BIP. I can pull it out and plug it into another machine very easily. I have been sorting through some old directories and files, archiving some, sharing others with colleagues. For instance, a little dated but if you were looking for a list of Publisher reports available in EBS R12.1, here it is. Im trying to track down a more recent R12 instance and will re-post the document. I also found another gem; its a little out there in terms of usefulness but Im sharing it none the less. You can embed, locally or remotely reference SVG graphics (in XML format) and bring the images into the BIP outputs. Template and sample data here. A nice set of templates showing page number control and page suppression - they will need some explanation, so I'll save them for another post. The list goes on but I'll save them for later. Back to the clean up!

• Why job postings always looking for "rockstars?" [closed]

  - by Xepoch

  I have noticed a recent trend in requesting programmers who are rockstars. I get it, they're looking for someone who is really good at what they do. But why (pray) make the reference to a rockstar? Do these companies really want these traits as a real rockstar? Party all night and wake up to take care of quick business in the morning? Substance abuse, Narcissism with celebrity, Compensation well exceeding their management, Excellent at putting on a short-lived show, Entertainment instead of value, 1 hit (project) wonders or single-genre performers, Et cetera What is wrong with Senior or Principal Software Engineer who has an established and proven passion for the business? Rather do we mean quite the opposite, someone who: rolls up the sleeves and gets to work, takes appropriate direction and helps influence teams, programs in lessons' learned and proper practices, provides timely communication to the whole team, can code and understand multiple languages, understands the science and theory behind computation, Is there a trend to diversify the software engineering ranks? How many software rockstars can you hire before your band starts breaking up? Sure, there are lots of folks doing this stuff on their own, maybe even a rare few who do coding for show, but I wager the majority is for business. I don't see ads for rockstar accountants, or rockstar machinists, or rockstart CFOs. What makes the software programmer and their hiring departments lean towards this kind of job title?

• Installation questions

  - by user12609425

  I've gotten a couple more questions about the installation process for Ops Center. "Can I install on any SPARC / X86 based platform?" Ops Center can run on Oracle Solaris on either architecture, or on Linux. The Certified Systems Matrix lists the supported OSes, and the Linux and Solaris install guides go into more detail about the hardware and OS requirements. "Can we install it on local zones or LDOMS?" Zones, yes; LDOMS, sort of. You can install the Enterprise Controller in a local zone. There are a few caveats, which are explained in the Preparing a Non-Global Zone section. You can also install a Proxy Controller in an Oracle Solaris 11 zone. Agent Controllers, which are the part of the infrastructure that's installed on managed systems, can be put on zones or LDOMS. "Do we need any dedicated network ports from all agent monitoring systems?"  Yes. The port requirements are covered in the Network Port Requirements and Protocols table, which is in the feature reference guide as well as in the install guides.

  Simple Shell script echo "Enter 1 for month of March" echo "Enter 2 for month of April" echo "Enter 3 for month of May" read Month case "$Month" in 1) echo "enter establishment name" read a; mysql -u root -p $a < "March.sql";; 2) echo "enter establishment name" read b; mysql -u root -p $b < "April.sql";; 3) echo "enter establishment name" read c; mysql -u root -p $c < "May.sql";; esac done In this i have three other query files March.sql, April.sql, May.sql. i'm linking this in shell script . Example of .sql file: SELECT DISTINCT substr( a.case_no, 3, 2 ), b.case_type, b.type_name, a.case_no into outfile '/tmp/April.csv' FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\r\n' FROM Civil_t AS a, Case_type_t AS b, disposal_proc AS c WHERE substr( a.case_no, 3, 2 ) = b.case_type AND a.date_of_decision BETWEEN '2014-04-01' AND '2014-04-30' AND a.case_no = c.case_no AND a.court_no =1; I have to alter the .sql script every time. Is there any method to read the variables from shell script and use it in mysql. For example:- echo "enter date" read a #input date Now i have read a "date" and i want to use it in March.sql query in where clause. Is there is any method of using this variable in .sql query.

• How to create repeatable table with unique ID's using jQuery

  - by milbert

  I need to create a table structure that can be "copied" and populated with a new set of data. However, each table must have unique IDs for functions that must access them later. For example: <table class="main"> <thead><tr><th class="header"></th></tr></thead> <tbody> <tr class="row"><td class="col0"></td><td class="col1"></td></tr> </tbody> </table> My current thought is to use jQuery to load the table from a seperate html file into a variable. Using this saved table I could then create a function that copies it, traverses the table to add an ID to each section where information will need to be appended from a seperate data source, and return this new table. I am new to jQuery and feel like I may be missing an easier/better way to accomplish this. Any help on this subject would be appreciated.

• HTML Manifest for Content Folios

  - by Kyle Hatlestad

  I recently worked on a project to create a custom content folio renderer in WebCenter Content. It needed to output the native files in the folio along with a manifest file in HTML format which would list the contents of the folio along with any designated metadata and a relative link to the file within the download.  This way a person could hand someone the folio download and it would be a self-contained package with all of the content and a single file to display the information on the contents.  The default Zip rendition of the folio will output the web-viewable version of the file with an HDA formatted file for each one. And unless you are fluent in HDA or have a tool to read them, they are difficult to consume. I thought this might be useful for others, so I'm posting a copy of the component here. Beyond the standard instructions for installing a component, there is an environment configuration file (folionativezipwithmanifestrenderer_environment.cfg) which has a couple of options. FolioMetadataManifestList - This is a comma separated list of metadata fields (system or custom) that should be included in the manifest file. FolioMetadataManifestUseOriginalFilename - (True or False) If set to True, the filenames in the zip file will be based on the original filename as it was checked into WebCenter Content.  If False, it will use the 'Name' of the item as defined within the Folio.  This is usually the Title of the item. The component also includes the source code, so feel free to use this as a reference for creating other interesting folios.

• How to dynamically override a method in an object

  - by Ace Takwas

  If this is possible, how can I change what a method does after I might have created an instance of that class and wish to keep the reference to that object but override a public method in it's class' definition? Here's my code: package time_applet; public class TimerGroup implements Runnable{ private Timer hour, min, sec; private Thread hourThread, minThread, secThread; public TimerGroup(){ hour = new HourTimer(); min = new MinuteTimer(); sec = new SecondTimer(); } public void run(){ hourThread.start(); minThread.start(); secThread.start(); } /*Please pay close attention to this method*/ private Timer activateHourTimer(int start_time){ hour = new HourTimer(start_time){ public void run(){ while (true){ if(min.changed)//min.getTime() == 0) changeTime(); } } }; hourThread = new Thread(hour); return hour; } private Timer activateMinuteTimer(int start_time){ min = new MinuteTimer(start_time){ public void run(){ while (true){ if(sec.changed)//sec.getTime() == 0) changeTime(); } } }; minThread = new Thread(min); return min; } private Timer activateSecondTimer(int start_time){ sec = new SecondTimer(start_time); secThread = new Thread(sec); return sec; } public Timer addTimer(Timer timer){ if (timer instanceof HourTimer){ hour = timer; return activateHourTimer(timer.getTime()); } else if (timer instanceof MinuteTimer){ min = timer; return activateMinuteTimer(timer.getTime()); } else{ sec = timer; return activateSecondTimer(timer.getTime()); } } } So for example in the method activateHourTimer(), I would like to override the run() method of the hour object without having to create a new object. How do I go about that?

• Google Analytics custom variables and how are they recorded?

  - by mrtsherman

  I have been asked to add GA custom variable tracking to my company's website. The company website uses server side includes, so making modifications to the tracking code happens identically everywhere. Maintenance is therefore a headache. Also, GA takes about twenty-four hours for custom variables to start showing up in reports and that makes troubleshooting a headache. So if you have custom variables // visitor level tracking, id = 12345 _gaq.push(['_setCustomVar', 1, 'id', '12345', 1]); // page level tracking, email = [email protected] _gaq.push(['_setCustomVar', 1, 'email', '[email protected]', 1]); The marketing people want the following out of this: User visits site and we record a unique id for them. Whenever they return this id will be used in GA. User signs up for our newsletter on page X and we record their email address. Whenever they return this email address is used in GA. Now a big problem for me is that I don't use GA and the marketing people don't use custom variables. So we don't actually know how this will work. Do I want Page, Session or Visitor level tracking? What happens because the same GA code is used on every page? If they visit the email sign up form and we record the email address, but then they go somewhere else where email is nonexistent will the value get 'overwritten.' Sorry for the long question, but there are a lot of unknowns for a GA noob.

• Draw "vision cone" / targetting element onto game world

  - by gkimsey

  I'm wanting to indicate various things using a "pie slice" sort of shape as below. Similar to vision cones in stealth game minimaps, or targetting indicators in RTS type games for frontal area attacks. Something generic enough to be used for both would be ideal. I need to be able to procedurally (and efficiently) change things like the slice width and length, color, transparency, position in the world, etc. For my particular situation, there's no concern with elevation, funky terrain, or really any third axis at all as far as this element is concerned. I have two first inclinations on how to accomplish this: 1) Manually generate the vertices for a main triangle, (possibly two, superimposed to get the border effect), a handful more to approximate the arc at the end, and roll it into a mesh. 2) Use some sort of 2D drawing library to create a circle and mask it off at the right angles, render to texture, and use that. For reference, I have some experience with Ogre3D, but I'm not attached to it as this is a mostly academic pursuit at the moment. Other technologies that might be better at accomplishing this are more than welcome. Finally, I'm kind of curious about how to do a "flashlight" or similar 3D effect that could produce the same result, but on all surfaces in the lit area.

• CSOM (Client Side Object Model) - What's new with SharePoint 2013

  SharePoint CSOMThe Client-Side Object Model or CSOM came out with SharePoint 2010. CSOM is accessible through client.svc but all client.svc calls must go through supported WFC entry points (supported entry points are .NET, Silverlight and JavaScript). So a developer would need to use client side proxy objects exposed by either a .NET assembly or a JavaScript library. Changes with SharePoint 2013REST Capabilities - Direct access to client.svcNew APIs - App ModelREST CapabilitiesOne of the most important changes to the CSOM with SharePoint 2013 is that the web service entry point of client.svc has been extended to allow direct access  via REST-Based web service calls. This is a really critical change since its going to make the SharePoint platform accessible to any other platform, opening the horizons of integration and collaboration with other REST based platforms and devices. OData (a really popular standard data access API for HTTP-based clients) is supported similar to 2010 but will be a more important aspect of SharePoint 2013 development.New API'sCSOM for SharePoint 2013 has been buffed up with several new APIs for not only SharePoint server functionality but also an API for Windows Phone applications. For a SharePoint 2010 farm most of the new APIs mentioned below are available only via server side APIs:SearchTaxonomyPublishingWorkflowUser ProfilesE-DiscoveryAnalyticsBusiness DataIRMFeedsSharePoint 2013 remote APIs being accessible through both CSOM and REST is very important to the new app model where developers can no longer run code in a SharePoint environment nor can they access the server-side APIs. So CSOM plays the savior here.Also, you can now substitute the alias '_api' in order to reference '_vti_bin/client.svc'.

• How to Downgrade Razor 3 and fix the issue that CSHTML not work in VS10,12 ?

  - by Anirudha

  Originally posted on: http://geekswithblogs.net/anirugu/archive/2013/11/04/how-to-downgrade-razor-3-and-fix-the-issue-that.aspxFew days ago I migrate a project to MVC 4 and suddenly I have seen that MVC project’s cshtml file is no longer working. The problem happen because my project is now based on Razor 3 RC and VS12 doesn’t even have support it. (Remember that VS team will ship support in VS update 4). My migration update it to Razor 3 (which is not related to MVC 4, MVC 4 used old version of Razor 2).   So how to fix the problem. Since VS update 4 in development and MVC 3 support exist in both old Version of VS (10,12) then better to migrate back our Razor to old version so we can use our project in VS 10 or 12. If your project have Razor 3 and it seem that Syntax highlighting doesn’t work for you then I suggest you to try this Nuget package https://www.nuget.org/packages/UpgradeMvc3ToMvc4 Remember that this will not be succeed. What you need to do is delete package folder in your project and now open the packages.config remove all entry of package now.   Now Run this command PM> Install-Package UpgradeMvc3ToMvc4 If this is failed then see what thing make error in console. simply remove the reference and try again. Now run it and see this will work.   After run this you will see that WebGrease Dll have a version number issue. Simply update it to version 1.5.2 and now you have ready your project to run it in .net 4. If you do bin deployment then you don’t need to have installed MVC 4 on server either. Remember that MVC 5 is based on .net 4.5 which simply means you can’t run it in VS10. until VS12 update 4 MVC 5 cshtml page will be work as simple html pages (syntax highlighting and intellisense).

• Movement on the X an Z axis are combined?

  - by Magicaxis

  This is probably a stupid question, but I'm trying to simply move a 3D object up, down, left, and right (Not forward or backward). The Y axis works fine, but when I increment the object's X position, the object moves BOTH right and backwards! when I decrement X, left and forwards! setPosition(getPosition().X + 2/*times deltatime*/, getPosition().Y, getPosition().Z); I was astonished that XNA doesnt have its own setPosition function, so I made a parent class for all objects with a setPosition and Draw function. Setposition simply edits a variable "mPosition" and passes it to the common draw function: // Copy any parent transforms. Matrix[] transforms = new Matrix[block.Bones.Count]; block.CopyAbsoluteBoneTransformsTo(transforms); // Draw the model. A model can have multiple meshes, so loop. foreach (ModelMesh mesh in block.Meshes) { // This is where the mesh orientation is set, as well // as our camera and projection. foreach (BasicEffect effect in mesh.Effects) { effect.EnableDefaultLighting(); effect.World = transforms[mesh.ParentBone.Index] * Matrix.CreateRotationY(MathHelper.ToRadians(mOrientation.Y)) * Matrix.CreateTranslation(mPosition); effect.View = game1.getView(); effect.Projection = game1.getProjection(); } // Draw the mesh, using the effects set above. mesh.Draw(); } I tried to work it out by attempting to increment and decrement the Z axis, but nothing happens?! So using the X axis changes the objects x and z axis', but changing the Z does nothing. Great. So how do I seperate the X and Z axis movement?
