• Looking Under the Hood of ...

  - by rickramsey

  copyright 2012 Rob Lang Fair is fair. Our last post featured a conversation with the beautiful and talented Eva Mendez, so today we're featuring something for those of you who prefer the other gender of our fair species. This dude has quite the hardware challenge ahead of him. He hasn't begun to find out what's really under that hood. Life is much easier for you and me, thanks to Jeff Wright and Suzanne Zorn. They wrote a wicked cool article about Oracle VM Server for SPARC. Here's a little bit about it... Looking Under the Hood of Networking in Oracle VM Server for x86 Oracle VM Server for SPARC lets you create logical networks out of physical Ethernet ports, bonded ports, VLAN segments, virtual MAC addresses (VNICs), and network channels. You can then assign channels (or "roles") to each logical network so that it handles the type of traffic you want it to. Greg King explains how you go about doing this, and how Oracle VM Server for SPARC implements the network infrastructure you configured. He also describes how the VM interacts with paravirtualized guest operating systems, hardware virtualized operating systems, and VLANs. Finally, he provides an example that shows you how it all looks from the VM Manager view, the logical view, and the command line view of Oracle VM Server for x86. More Resources for Oracle VM Server for x86 If you liked Greg and Suzanne's paper, you can ...

• Friday Tips #6, Part 2

  - by Chris Kawalek

  Here is a question about updating Oracle VM: Question: How can I perform Oracle VM 3 server updates from Oracle VM Manager? Answer by Gregory King, Principal Best Practices Consultant, Oracle VM Product Management: Server Update Manager is a built-in feature of the Oracle VM Manager. Basically, Server Update Manager automatically configures YUM updates on all the Oracle VM Servers, pointing each to our Unbreakable Linux Network (ULN) update channel for Oracle VM. The servers periodically check with our Oracle YUM repository and notify the Oracle VM Manager that an update is available for each server. Actual server updates must be triggered by the Oracle VM administrator – they are not executed automatically. At this point, you can use the Oracle VM Manager to put a server into maintenance mode which live migrates all the running Oracle VM Guests to other Oracle VM Servers in the server pool. Once all the Oracle VM Guests have been migrated, the Oracle VM administrator can trigger the update on the server. The entire process is documented in the Installation and Upgrade Guide of Oracle VM Documentation so I won’t spend time detailing the steps. However, configuring the Server Update Manager is exceedingly simple. Simply navigate to the Tools and Resources tab in the Oracle VM Manager, select the link for Server Update Manager and ensure the following values are added to the text boxes as shown in the illustration below: YUM Base URL: http://public-yum.oracle.com/repo/OracleVM/OVM3/latest/x86_64 YUM GPG Key: file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle Every server in the pool will be automatically configured for YUM updates once you choose the Apply button. Many thanks to Greg and Rick for providing the answers to this week's questions. If you want to ask us something, hit up Twitter and use hashtag #AskOracleVirtualization. See you next week! -Chris

• Further question on Intel graphics driver

  - by Thomas Byers

  Ok, Josh answered almost immed.! I need to know specifically, now that I am using Nvidia card effectively, do I need to allow update manager to update the intel gr. drivers? I must add, I believe I know why Update Manager is telling me I need to update those Intel gr. drivers. It probably happened because I tried to update my nvidia drivers and got a buggy install, which let to to a black screen. I shut the system down manually after that and rebooted to a black screen and upon a further reboot I ascertained that I could still dual-boot(windows 7) into the other os. Then I went through the restart process and at the grub2 menu chose other options and it was probably, at that time, that Linux was smart enough to know that nvidia drivers as installed weren't cutting it, and reverted to the onboard Intel graphics system...does that make sense? Anyway, after successfully getting up and running, I reinstalled my old but successful nvidia drivers and all was well again, except now upon running Update Manager, I am offered the Intel graphics driver upgrade each time, which, up til now I have unchecked...my question is now more obvious. Should I accept the Intel driver update and if I do, will it once again override my nvidia drivers?

• Thoughts on type aliases/synonyms?

  - by Rei Miyasaka

  I'm going to try my best to frame this question in a way that doesn't result in a language war or list, because I think there could be a good, technical answer to this question. Different languages support type aliases to varying degrees. C# allows type aliases to be declared at the beginning of each code file, and they're valid only throughout that file. Languages like ML/Haskell use type aliases probably as much as they use type definitions. C/C++ are sort of a Wild West, with typedef and #define often being used seemingly interchangeably to alias types. The upsides of type aliasing don't invoke too much dispute: It makes it convenient to define composite types that are described naturally by the language, e.g. type Coordinate = float * float or type String = [Char]. Long names can be shortened: using DSBA = System.Diagnostics.DebuggerStepBoundaryAttribute. In languages like ML or Haskell, where function parameters often don't have names, type aliases provide a semblance of self-documentation. The downside is a bit more iffy: aliases can proliferate, making it difficult to read and understand code or to learn a platform. The Win32 API is a good example, with its DWORD = int and its HINSTANCE = HANDLE = void* and its LPHANDLE = HANDLE FAR* and such. In all of these cases it hardly makes any sense to distinguish between a HANDLE and a void pointer or a DWORD and an integer etc.. Setting aside the philosophical debate of whether a king should give complete freedom to their subjects and let them be responsible for themselves or whether they should have all of their questionable actions intervened, could there be a happy medium that would allow the benefits of type aliasing while mitigating the risk of its abuse? As an example, the issue of long names can be solved by good autocomplete features. Visual Studio 2010 for instance will alllow you to type DSBA in order to refer Intellisense to System.Diagnostics.DebuggerStepBoundaryAttribute. Could there be other features that would provide the other benefits of type aliasing more safely?

• JavaOne LAD Call for Papers

  - by Tori Wieldt

  JavaOne LAD Call for Papers closes next Friday, October 4. Here are Java Evangelist Steven Chin's top three reasons why you submit a session:1) Imagine a parallel world where Java is king. Where the government has mandated that all software be open-source and recognized Java as an official platform. That is exactly what happened in Brazil and it shows in all aspects of their country from government systems to TV standards.2) A JUG in Every Village - Brazil has the most user groups of any country in the world by a significant margin. "I've stayed after JavaOne to visit several cities and gotten a great audience whether it was a large city like Brasilia or Goiania, or a coastal town like Fortaleza, Salvador, or Maceio," Chin explains.3) A Community-Supported Conference - SouJava and the entire Brazilian user group community is active and involved with JavaOne Brazil, making it a really engaging regional JavaOne conference. Submissions should be: From the community, all proposals should be non-Oracle. Java-related topics (not technologies such as Flex, .NET, Objective C, etc... unless it's specifically a topic about how such things INTEGRATE with Java) Non-product pitches Interesting/innovative uses of Java Practical relevant case studies/examples/practices/etc. The call for papers will close on Friday, October 4, 2012 at 11:59 pm local time. We look forward to hearing from you!

• PHP mySQL count number of fields not empty

  - by Pez Cuckow

  I have a database of users where they can send messages to other users (up to four) and the ID of the message they sent is in their user row. e.g. Name, Email, Msg1, Msg2, Msg3, Msg4 Pez, [email protected], 1, 55, 42, 5 //Send 4 messages Steve, [email protected], 0, 0, 0, 0 //Send 0 messages Leon, [email protected], 3, 0, 3, 5 //Send 3 messages How in a MySQL query can I get the amount of those message rows that are not empty or not equal to 0, allowing me to order by that? So it would return Pez - 4 Mesasges Leon - 3 Messages Steve - 0 Messages Im my mind something like order by count(!empty(msg1)+!empty(msg2)+!empty(msg3)+!empty(msg4)) Many thanks,

• Value of text box disapears - binding viewmodel to a tab (content control)

  - by Eli Perpinyal

  Based on the MVVM example by Josh Smith, I have implemented the multi tab option which binds to a different tab to a different view model using a simple datatemplate that binds a viewmodel to a view. <DataTemplate DataType="{x:Type fixtureVM:SearchViewModel}"> <SearchVw:SearchView/> </DataTemplate> The issue that I'm having, is when I switch tabs and then switch back again, the value in the textbox disappears. When I bind the Text in the textbox to a value in the ViewModel it does not disappear. This is fine, and I can overcome this but I am having another issue for example with the position of the scroll bar in a grid disappearing once the tab has lost focus. Why is the value disappearing? I'm assuming it is a WPF sub system task that cleans up resources!? how can I avoid this? I also feel it might be slowing down my app.

• Object as an array

  - by owca

  I need to create class Dog and PurebredDog extending Dog. Problem is that Dog can be at once single object and array of objects (Dogs and PurebreedDogs : Dog pack[]={new Dog(76589,"As","black",18, "Ann","Kowalsky"), new PurebreedDog(45321,"Labrador","Elf","black",25, "Angus","Mati","Barbara","Smith"), new Dog(102467,"Gamma","brown",89, "Josh","Coke"), new PurebreedDog(9678,"York","Theta","brown",8, "Emka","Figaro","Alice","Cat")}; for(int i=0; i < pack.length; i++) System.out.println(pack[i]+"\n\n"); How to write proper constructor for Dog ?

• masked input: I can't get the simplest completion to work

  - by Karl Messner

  Trying to use Josh Bush's masked input plugin. I want to shift focus and do other things once the person puts their cell phone in. I mask to a phone shape. When I hit the last letter, I want it to trigger a javascript function. Right now that function just alerts hi. But I can't get it to work: function jump(){ alert('hi'); } $(document).ready(function(){ $("#cellphone").focus(); jQuery(function($){ $("#product").mask("(999) 999-9999",{completed:function(){jump();}}); }); });

• Rewriting a Subdomain with mod-rewrite

  - by resonantmedia

  I have a project that uses the moodle library. I had to change the URL from moodle.example.com to learn.example.com, due to a client request. I thought this would be an easy change, but alas moodle inserts all links and images in with the complete url instead of the relative url. Is it possible using mod-rewrite to point all requests to moodle.example.com to learn.example.com and maintain the query string? Example: I want a request to: http://moodle.example.com/course/view.php?id=2&topic=1 to go to http://learn.example.com/course/view.php?id=2&topic=1. Is this possible? Thanks, Josh

• Can't pass a single parameter to lambda function in MVVM Light Toolkit's RelayCommand

  - by Dave

  I don't know if there's a difference between Josh Smith's and Laurent Bugnion's implementations of RelayCommand or not, but everywhere I've looked, it sounds like the Execute portion of RelayCommand can take 0 or 1 parameters. I've only been able to get it to work with 0. When I try something like: public class Test { public RelayCommand MyCommand { get; set; } public Test() { MyCommand = new RelayCommand((param) => SomeFunc(param)); } private void SomeFunc( object param) { } } I get the error: Delegate 'System.Action' does not take '1' arguments. Just to make sure I am not insane, I went to the definition of RelayCommand to make sure I didn't have some rogue implementation in my solution somewhere, but sure enough, it was just Action, and not Action<. What on earth am I missing here?

• Is this a good code (came across while reading code of a colleague)

  - by eriks

  // file a.hpp class a; typedef boost::shared_ptr<a> aPtr class a{ public: static aPtr CreateImp(); virtual void Foo() = 0 ; .... }; //file aImp.hpp class aImp : public a{ virtual void Foo(); }; //file aImp.cpp aPtr a::CreateImp() { return aPtr(new aImp()); } void aImp::Foo(){} The client must use CreateImp to get ptr to 'a', and can't use 'a' other ways. What do you think about this implementation? what do you think about this king of implementation?

• Computing unique index for every poker starting hand

  - by Aly

  As there are 52 cards in a deck we know there are 52 choose 2 = 1326 distinct matchups, however in preflop poker this can be bucketed into 169 different hands such as AK offsuit and AK suited as whether it is A hearts K hearts or A spade K spades it makes no difference preflop. My question is, is there a nice mathematical property in which I can uniquely index each of these 169 hands (from 0 to 168 preferably). I am trying to create a look up table as a double[][] = new double [169][169] but have no way of changing a hand representation such as AKs (an Ace and a King of the same suit) to a unique index in this array.

• NSNumber >= 13 won't retain. Everything else will.

  - by jkap

  The code I'm currently working on requires adding an NSNumber object to an array. All of the NSNumbers with value 0-12 are added fine, but 13 onward causes a EXC_BAD_ACCESS. I turned on NSZombieEnabled and am now getting *** -[CFNumber retain]: message sent to deallocated instance 0x3c78420. Here's the call stack: #0 0x01eac3a7 in ___forwarding___ #1 0x01e886c2 in __forwarding_prep_0___ #2 0x01e3f988 in CFRetain #3 0x01e4b586 in _CFArrayReplaceValues #4 0x0002a2f9 in -[NSCFArray insertObject:atIndex:] #5 0x0002a274 in -[NSCFArray addObject:] #6 0x00010a3b in -[Faves addObject:] at Faves.m:24 #7 0x000062ff in -[ShowController processFave] at ShowController.m:458 #8 0x002af405 in -[UIApplication sendAction:to:from:forEvent:] #9 0x00312b4e in -[UIControl sendAction:to:forEvent:] #10 0x00314d6f in -[UIControl(Internal) _sendActionsForEvents:withEvent:] #11 0x00313abb in -[UIControl touchesEnded:withEvent:] #12 0x002c8ddf in -[UIWindow _sendTouchesForEvent:] #13 0x002b27c8 in -[UIApplication sendEvent:] #14 0x002b9061 in _UIApplicationHandleEvent #15 0x02566d59 in PurpleEventCallback #16 0x01e83b80 in CFRunLoopRunSpecific #17 0x01e82c48 in CFRunLoopRunInMode #18 0x02565615 in GSEventRunModal #19 0x025656da in GSEventRun #20 0x002b9faf in UIApplicationMain #21 0x00002498 in main at main.m:14 If it wasn't isolated to NSNumbers of a certain range, I'd assume I screwed something up with my memory management, but I've just got no idea. Any ideas? Thanks, Josh

• How Can I Add a New Command to a Control's Event

  - by Chris

  Hi, thanks for taking a look at this question. I have been building an application (VB/WPF) following Josh Smith's example of an MVVM pattern: Click here to view My Views have Controls which trigger a Command upon an event, such as a button click and these are bound to properties in the ViewModel. My ViewModel exposes properties of type ICommand which invoke the appropriate methods. This has worked well, until now! I now want to use a Thumb Control to allow a user to move an object within a Canvas. I don't believe that the Thumb has a Command capability 'out of the box'. A Thumb raises a 'DragDelta' event when being moved. So my question is as follows: How do I extend a Control's capability to issue a Command upon an event please? I wish to issue a new Command, let's say 'onDragDelta' so that I can bind it to a property in my ViewModel just like my Buttons. Thank you very much

• Is it possible to resize a SpriteAsset without adding it to the display list?

  - by Sophistifunk

  Hi guys, I have an embedded image asset (with a scale9 grid), and I'm trying to get the bitmapdata when it's resized, but I can't seem to do this without adding it to the display list. I try this: spriteAsset.setActualSize(w,h); spriteAsset.width = w; bmd.draw(spriteAsset); But when I then draw out the bitmapdata with graphics.beginBitmapFill(), I just get the original un-stretched image. Any pointers? Or do I need to take 9 separate BitmapData images and make 9 separate bitmap fills? Cheers, -Josh

• Getting started in Mac Development; No Mac.... What Do?!

  - by Andrew Bolster

  Hi folks, With all the RDF et al around King Jobs' newest glass beermat, I'm getting the feeling that its a good time to add the 'iphone/ipad developer' string to my bow. One problem (two if you count not being in a financial position to slap down $1000+ for a mac) ; I am a PC head, specifically a Linux-head, and have no regular access to a Mac platform to develop on. I cannot see any way of getting my hands on iSDK without being on a Mac, (but have been known to be wrong) How hopeless is my plight and where can I go from here?
