• New MyOracleSupport (MOS)Interface Coming 13 July 2012

  - by user793553

  On July 13, 2012, we plan to upgrade the My Oracle Support HTML-based user interface (UI) with additional functionality that will allow those users remaining on the Flash-based user interface to switch over to the HTML version. Our goal is to provide a single-online support portal so that all My Oracle Support users can benefit from the same features and functionality. Prior to July 13, 2012, users of Oracle On Demand, Oracle CRM On Demand, Taleo, and Oracle Configuration Manager should continue accessing the My Oracle Support Flash-based user interface. After July 13, 2012, the above features and functionality to support these users will be available on the HTML interface. All other users of My Oracle Support can make the switch now. Benefits of using the HTML-based user interface include: Streamlined, three-step process for initiating new Service Requests (SRs) Single, consistent workflow for both hardware and software incidents Enhanced personalization and filtering within the user interface New accessibility features (enabling screen readers, large fonts, etc.) Additionally, please note Internet Explorer 6 (IE6) will no longer be supported. For further information, please check Doc ID 1385682.1

• Will Tracking Subdomains as Single Entity with Google Analytics Help SEO? [closed]

  - by Sam Gridley

  Possible Duplicate: Does Google Analytics data affect SEO? We have two subdomains, one for our blog and one for our ecommerce store. The blog serves to bring traffic and the store is how we monetize the site. We have them designed to appear as one large site, but I know google sees them as two sites. Here is how the subdomains look: www.example.com (store) blog.example.com (blog) I believe I can configure analytics to use subdomain tracking as explained here: http://support.google.com/googleanalytics/bin/answer.py?hl=en&answer=55524 But my question is whether this will cause google to see our 2 subdomains as one larger domain for SEO purposes. In other words, is there any relationship to how you configure google analytics and how google indexes and ranks your website(s) and pages? Is there anything I need to do in anaytics or webmaster tools to make google aware that these two subdomains work together as one website? Thanks! Sam

• Is "PHP and MySQL Web Development, 4th ed." an outdated book to learn from?

  - by ForeverLearnNeverMaster

  I want to get into web stuff, and thought of going with PHP+MySQL. I have experience in C#, C++, desktop graphics, but no web stuff besides HTML, CSS which I started learning 2 months ago. On SO PHP-book question, the highest rated book is "PHP Objects, Patterns and Practice". However, I'm not sure if it's a book to start PHP with... or is it? Most of the books mentioned in that SO question seem to be for those who already know PHP. I considered "PHP & MySQL Web Development, 4th Ed.", but someone mentioned that "it uses the mysql_* functions which are almost deprecated." Help?

• How can I work out how many IP addresses there are in a given range?

  - by Jarede

  I'm wondering if there is a formula to work out the amount of IP addresses in a given range. I have a system that takes either a single IP address or a start and and end IP address: A single one might be: 145.16.23.241 A range might be: 145.16.23.122 - 145.16.23.144 The people inputting these aren't technical, nor are they receiving these details from technical people, so suggesting using CIDR notation isn't an answer for me. I want to be able to highlight that when entering a range such as: 122.100.10.12 - 128.10.200.140 it might not actually be a range and rather 2 singular IP addresses since such a range would comprise of x (large number of) IP addresses. Is there a basic formula to help me highlight this?

• Q&amp;A: Will my favourite ORM Foo work with SQL Azure?

  - by Eric Nelson

  short answer: Quite probably, as SQL Azure is very similar to SQL Server longer answer: Object Relational Mappers (ORMs) that work with SQL Server are likely but not guaranteed to work with SQL Azure. The differences between the RDBMS versions are small – but may cause problems, for example in tools used to create the mapping between objects and tables or in generated SQL from the ORM which expects “certain things” :-) More specifically: ADO.NET Entity Framework / LINQ to Entities can be used with SQL Azure, but the Visual Studio designer does not currently work. You will need to point the designer at a version of your database running of SQL Server to create the mapping, then change the connection details to run against SQL Azure. LINQ to SQL has similar issues to ADO.NET Entity Framework above NHibernate can be used against SQL Azure DevExpress XPO supports SQL Azure from version 9.3 DataObjects.Net supports SQL Azure Open Access from Telerik works “seamlessly”  - their words not mine :-) The list above is by no means comprehensive – please leave a comment with details of other ORMs that work (or do not work) with SQL Azure.

• In OpenGl ES 2, should I allocate multiple transformation matrices?

  - by thm4ter

  In OpenGl ES 2, should I declare just one transformation matrix, and share it across all objects or should I declare a transformation matrix in each object that needs it? for clarification... something like this: public class someclass{ public static float[16] transMatrix = new float[16]; ... public static void translate(int x, int y){ //do translation here } } public class someotherclass{ ... void draw(GL10 unused){ someclass.translate(10,10); //draw } } verses something like this: public class obj1{ public static float[16] transMatrix = new float[16]; ... void draw(GL10 unused){ //translate //draw } } public class obj2{ public static float[16] transMatrix = new float[16]; ... void draw(GL10 unused){ //translate //draw } }

• "A good programmer can be as 10+ times more productive as a mediocre one"

  - by m3th0dman

  I had read an interview with a great programmer (it is not in English) and in it he said that "a great programmer can be as 100 times as good as a mediocre one" giving reason for why good programmers are very well paid and why programming companies give many facilities for their employees. The idea was that there is a very large demand for good programmers, because of the above reason and that's why companies pay very much to bring them. Do you agree with this statement? Do you know any objective facts that could support it? Edit: The question has nothing to do with experience; if you talk about one great programmer with 1 year experience then s/he should be 10 times more productive than a mediocre programmer with 1 year experience. I agree that from certain experience years onwards, things start to dissipate but that's not the purpose of the question.

• Difference between Sound and Music

  - by Southpaw Hare

  What are the key differences between the Sound and Music classes in Pygame? What are the limitations of each? In what situation would one use one or the other? Is there a benefit to using them in an unintuitive way such as using Sound objects to play music files or visa-versa? Are there specifically issues with channel limitations, and do one or both have the potential to be dropped from their channel unreliably? What are the risks of playing music as a Sound?

• Deprecate a web API: Best Practices?

  - by TheLQ

  Eventually you need to depreciate parts of your public web API. However I'm confused on what would be the best way to do it. If you have a large 3rd party app base just yanking old versions of the API seems like the wrong way to do it as almost all apps would fail overnight. However you can't keep ancient web api's available forever as it might be outdated or there are significant changes that make working with it impossible. What are some best practices for deprecating old web api's?

• Hello NHibernate! Quickstart with NHibernate (Part 1)

  - by BobPalmer

  When I first learned NHibernate, I could best describe the experience as less of a learning curve and more like a learning cliff.  A large part of that was the availability of tutorials.  In this first of a series of articles, I will be taking a crack at providing people new to NHibernate the information they need to quickly ramp up with NHibernate. For the first article, I've decided to address the gap of just giving folks enough code to get started.  No UI, no fluff - just enough to connect to a database and do some basic CRUD operations.  In future articles, I will discuss a repository pattern for NHibernate, parent-child relationships, and other more advanced topics. You can find the entire article via this Google Docs link: http://docs.google.com/Doc?docid=0AUP-rKyyUMKhZGczejdxeHZfOGMydHNqdGc0&hl=en Enjoy! -Bob

• What is an acceptable GC frequency for a SlimDX/Windows/.NET game?

  - by Rei Miyasaka

  I understand that the Windows GC is much better than the Xbox/WP7 GC, being that it's generational and multithreaded -- so I don't need to worry quite as much about avoiding memory allocation. SlimDX even has some unavoidable functions that generate some amount of garbage (specifically, MapSubresource creates DataBoxes), yet people don't seem to be too upset about it. I'd like to use some functional paradigms to write my code too, which also means creating objects like closures and monads. I know premature optimization isn't a good thing, but are there rules of thumb or metrics that I can follow to know whether I need to cut down on allocations? Is, say, one gen 0 GC per frame too much? One thing that has me stumped is object promotions. Gen 0 GCs will supposedly finish within a millisecond or two, but if I'm understanding correctly, it's the gen 1 and 2 promotions that start to hurt. I'm not too sure how I can predict/prevent these.

• Is having a class have a handleAction(type) method bad practice?

  - by zhenka

  My web application became a little too complicated to do everything in a controller so I had to build large wrapper classes for ORM models. The possible actions a user can trigger are all similar and after a certain point I realized that the best way to go would be to just have constructor method receive action type as a parameter to take care of the small differences internally, as opposed to either passing many arguments or doing a lot of things in the controller. Is this a good practice? I can't really give details for privacy issues.

• Program to Help Order Undated Photos

  - by Richard

  I have a large number of photos which have the correct DateTimeOriginal set in EXIF. I have about 300 photos for which the DateTimeOriginal is completely wrong. The DateTimeOriginals of these photos are not correlated, so I cannot change their time en masse. It must be done individually. I'm looking for a program that would essentially allow me to drag and drop the incorrectly time stamped photos into their place in the sequence of correctly time stamped photos. It would be nice to then be able to have the DateTimeOriginal tag updated, or the photos renamed chronologically. Thanks!

• The how of a collision engine

  - by JXPheonix

  This is a very, very broad question - what is the general algorithm of how a collision engine works? No code in specific, but rather, just a general idea of how a collision engine does what it does, constantly refreshing the points of an object and comparing it to other objects? (see, I have the general gist of it here.) A collision engine is basically an engine used in games (generally) so that your player (call him Bob), whenever bob moves into a wall, Bob stops, Bob does not walk through the wall. They also generally handle the gravity in a game and environmental things like that.

• Plan variable and call dependencies

  - by Gerenuk

  I'd like to write down the design of my program to understand the dependencies and calls better. I know there are class diagrams which show inheritance and attribute variables. However I'd also like to document the input parameters to method functions and in particular which calls the methods function executes inside (e.g. on the input parameters). Also sometimes it might be useful to show how actual objects are connected (if there is a standard structure). This way I can have a better understanding of the modules and design before starting to program. Can you suggest a method to do this software design? It should be one-to-one to programming code structure so that I really notice all quirks beforehand (instead of high-level design where thing are hard to implement without further work). Maybe some special diagram or tool or a combination? It is static dependency and call design rather than time dependent execution monitoring. (I use Python if you have any specialized recommendations).

• Store VOD wmi data in a database directly or use CQRS?

  - by JD01

  I need to collect Video on demand bandwidth usage every few minutes (or maybe ever few seconds) and store this in a database so users can produce graphs on bandwidth usage over a period of time (few hours, days, weeks or even possibly months). So the sort of data that will be stored will be the number of users watching videos, current server bandwidth (Mb/s), multicast bit rate etc. I am wondering whether using CQRS would be a good approach with Event sourcing as I can then rebuild my objects to create different projections (I.e. different graphs/reports etc) but then again it seems like I am introducing complexity which might not be needed. Or would it be best to just put the data directly in a database (currently using PostGres) directly and query off that? Having thought about it, my table is a form of audit log anyway, so I don't think I need event sourcing at all. Any thoughts?

• Bzr to git migration

  - by Sardathrion

  I am planning to do two things on several large (several gigs) and old (several years) repositories: Move from bzr to git without losing the commit history. Restructure all the repositories either using bzr or git. This will involve moving files/directories from one repository to another with its change history. Doing both at once would be foolish (I think!) but I am not sure which one should be done first. Any suggestions? Anything I should watch out for when migrating/restructuring?

• View Frustum Alternative

  - by Kuros

  I am working on a simulation project that requires me to have entities walking around in a 3D world. I have all that working, matrix transformations, etc. I'm at the point where I need what is essentially a view frustum, so I can give each entity a visible area. However, when looking over the calculations required to do it, it seems like a perspective frustum is only required to be able to project it onto a 2D screen. Is there another, easier to code solution, that would function better, such as an orthogonal perspective? Could I just define a shape mathematically and test wether the coordinates of the objects are inside or out? I am not really a 3D coder (and I am doing this all from scratch, not using an engine or anything), so I would like the simplest solution possible for my needs. Thank you!

• What measures can be taken to increase Google indexing speed for a given newly created page?

  - by knorv

  Consider a website with a large number of pages. New pages are published regularly. When publishing a new page the website operator wants to get the newly created paged indexed in Google as soon as possible. The website operator wants to minimize the time spent between publication and indexing. Consider the site http://www.example.com/ with hundreds of thousands of pages. The page page http://www.example.com/something/important-page.html is created at say 12:00. How do I get important-page.html indexed as soon as possible after 12:00? Ideally within seconds or minutes. Or more generally: What options are available to try to get Google to index a specific newly created page as soon as possible?

• How You Helped Shape Java EE 7...

  - by reza_rahman

  For many of us working with the JCP for years, the commitment to transparency and openness is very clear. For others, perhaps the most visible sign to date of this high regard for grassroots level input is a survey on Java EE 7 gathered a few months ago. The survey was designed to get open feedback on a number of critical issues central to the Java EE 7 umbrella specification including what APIs to include in the standard. The survey was highly successful with a large number of high quality responses. With Java EE 7 under our belt and the horizons for Java EE 8 emerging, this is a good time to thank everyone that took the survey once again for their thoughts and let you know what the impact of your voice actually was. I've posted the details on my personal blog. I hope you are encouraged by how your input to the survey helped shape Java EE 7 and continues to shape Java EE 8. Maybe now is the time for you to get more involved :-)?

• How can I neatly embed Flash in a page in a way that is cross-browser compatible?

  - by Mark Hatton

  When I receive Flash objects from my designer, it comes with an example HTML page which includes both <object> tags and <embed> tags as well as a whole heap of JavaScript. If I copy and paste this code in to my webpage, it works, but the code looks a mess (and there is so much of it!). If I remove the extra code and try either just <embed> or <object> on their own, it works in some browsers, but not others. Is there a neat, minimal method that works in all the major browsers?

• why would you use textures that are not a power of 2?

  - by Will

  In the early days of OpenGL and DirectX, it was required that textures were powers of two. This meant that interpolation of float values could be done very quickly using shifting and such. Since OpenGL 2.0, and preceding that via an extension, non-power-of-two texture dimensions has been supported. Are there performance advantages to sticking to power-of-two textures on modern integrated and discrete GPUs? What advantages do non-power-of-two textures have, if any? Are there large populations of desktop users who don't have cards that support non-power-of-two textures?
