For a project in e-learning courses I want to implement the standard scorm 2004 in my LMS (Learning management system), for that I did a little research about the standard. Among the results that I found, many articles talk about the "failure" of scorm 2004. The standard seems to me very little implemented in the existing LMS. This article Aticle scorm 2004, for example, indicates the disadvantages of the standard and compares it with the other standards ans we can see a very big difference. I also found on Internent that Moodle has abandoned the implementation of SCORM 2004 on its LMS. In addition, when we look at the documentation of the scorm 2004 (the books CAM, RTE and SN) we soon realize the completeness of the standard.
Do you think the standard has really failed?

Edit: in an attempt to avoid this question being closed as a reference request (though I still would appreciate references!), I will give a few general, non-link-only questions for concreteness. I would accept an answer for any of these, but the more the better.
Is the A12 in-order, or out-of-order?
How many instructions can it retire per cycle?
How many pipeline stages does it have?
What sort of cache hierarchy does it have?
Does it architecturally resemble modern Intel processors, and if not, what are the major differences?
Original question: There is a lot of publicly available documentation about how the current mainstream Intel core design works (Pentium Pro and all its descendants). Both Intel’s own optimization manuals, and descriptions published by WikiChip and Agner Fog.
Any curious person can learn what the pipeline stages are, what each part of the core does, and so on.
I can’t find anything similar for the Apple Ax series. Does it exist?
Apple is an ARM architectural licensee and they have developed several generations of ARM64 chips. A resource for some of the micro-architectural detail on their chips is the Cyclone LLVM scheduler model analyzed here. This is upstreamed into LLVM and also released by Apple as open source. I think the Cyclone model covers all their chips.
Other resources are WikiChip and Wikipedia which aggregate information and cite sources. The Apple patent file provides other information. Benchmarks and reviews are available but not at the level of Agner.
First, Wikipedia says the A12 is OOO but a Big Little chip. Big (Vortex) on the A12 decodes 7-wide and Little (Tempest) is 3-Wide with 13 and 5 execution ports respectively. I can't find retire rates.
I have spent a lot of time recently looking for some resources to help me to learn some more advanced techniques for developing AX 2009 SSRS reports. There is a lot of information available about making basic reports and Microsoft provides some nice walkthroughs.
What I am looking for is some more in-depth information covering more about writing business logic and methods in C#. Where can I locate some Code samples or even a solid technical book?
I trust you have found the great videos from Saveen Reddy. There are dozen of great videos explaining also into details on how you go about to make AX 2009 SSRS reports:

Furthermore, I would highly recommend having a look at the already created report libraries. Start off with the libraries ending with SRS (Like CustSRS and VendSRS). Just rightclick a library and choose to edit it in Visual Studio. I assume your environment is already set up for this.
Look into how some reports use queries to collect data directly and some use datamethods. By examining what is already in standard, you can learn a great deal of how to solve your own requirements.
I have one advice to you:
To develop a neat looking SSRS report, use SharedLibrary already exist project and use its styles.
I am making a design document and I need to draw pictures using Visio. I have searched through the Internet, but there is no getting started guide or tutorial. Can somebody help? I need a tutorial which helps me to draw figures of moderate complexity.
At the surface, this looks like a fairly straightforward question, but I would argue that there are some underlying problems inherent in what you are looking for. There are a couple of ways to address this question:
First, how to use Visio.. Finding that information is fairly straightforward. The documentation via the Help menu is handy when trying to determine how to actually add elements, tie them together and define schemas based on those elements (be it an E-R diagram, UML, or some other architectural diagram). Finding the tutorials you are seeking might be difficult as Microsoft has moved Visio from a standalone product, to a part of the Visual Studio Suite, to part of the Office Suite, back to a standalone product. I would start my search on MSDN. Here are a few resources:
Visio Insight - A blog dedicated to using and modifying Visio
A portion of the Visio documentation
Second, how to you develop diagrams (and perhaps more specifically architectural diagrams). This falls outside of the realm of Visio and moves more towards fundamentals. There are a lot of books on UML and diagramming problem domains. I keep a copy of the UML Cheat Sheet handy. The same goes for E-R diagrams as well as other models.
And finally, with a question: What kind of diagrams are you trying to create? As with all tools, make sure that Visio is the right tool for the job. Would the table diagraming system in SSMS work for you? How about the class diagraming system build into Visual Studio? (and this is just assuming you are using Microsoft technologies in order to develop software). Visio is great for creating flowcharts and systems diagrams as well -- and those are much more straightforward.
As one final note, check out some of the samples that should be included. Here is a link to some (albeit older) sample for Visio that should get you started.
You can always read a book on the tool and that's my personal preference. I learned Visio 2010 by reading the book "Microsoft Press Microsoft Visio 2010 Step by Step"
I am looking for some literature on CSLA.NET, does anyone have any direct links to/for this framework?
If someone also has time would you mind providing insight into this platform.
Thank you
One of the best sources of detailed information regarding CSLA is this book, written by Rocky:
Expert C# 2008 Business Objects
In this book, Rocky explains in detail not only how to apply the CSLA framework, but also how it is constructed.
Unfortunately this edition of the book only covers CSLA 3.x, not the current 4.0 release. However most of the priciples remain the same with some changes to implementation detail.
I learned from C# 2008 Business Objects and it's a great book. Besides learning the framework, you can learn a lot of oop principles that you can use outside the csla.net.
I am an senior-slash-"advanced" C#/.NET developer, currently using 3.5 Framework with WPF/WCF and Silverlight (WPF/E). I have come up right through 1.0 and 2.0 and so am well versed with the evolution of .NET. My next project could be "back" into 2.0 Framework, but with enough complexity (and time pressure) so as to call on "expert" skills, not just "advanced" ones.
Thus I am looking for a book with comprehensive coverage of the 2.0 Framework, primarily the organization and use of the libraries (by which, yes, I really just mean "the Framework"...) available in that rev. I want to have a complete, organized reference on hand for what tools are available in the box, so to speak, to choose the right ones at each step and not re-invent any wheels.
I own and love "CLR via C#", but this isn't a question about the CLR, it's about libraries (Framwork) primarily, and also interfacing techniques to .NET-supported related products.
If I "subtract out" my existing 3.0/3.5 knowledge/experience, I might say that I've only ever thoroughly investigated and used some 50-75% of the 2.0 Framework - so what I'd like to see is an authoritative guide to the full 100%. Doesn't need rigorous details or comprehensive examples, but rather a full assessment of scale and scope to be able to design and implement effective solutions in .net 2.0 "the right way".
C# 3.0 in a Nutshell covers parts of the framework in sufficient detail. I find it to be a very useful book to have around.
Programming Microsoft Visual C# 2005: The Base Class Library specifically covers the framework, but in my opinion the Nutshell book is better and you can always find additional information on MSDN.
Windows Forms Programming in C# covers WinForms in detail, or you may want to look at Chris Sells' book on WPF instead. I'm not familiar with the latter, but the first is okay.
It sounds like you have a good grasp on C# itself, so you probably want to know what was in 2.0 that isn't in 3.0 or 3.5. For this reason, you might be interested in some of the following resources, namely the C# 2.0 standard:
ECMA C# 2.0 Standard
C# 2.0 - The Complete Reference
Any of the C# books by Apress
I particularly like the C# 2.0 Complete Reference book, and keep a copy on my desk at home, but the C# 2.0 standard is incomparably good as well; it's just a question of whether you can stay awake long enough to get through any of it. :)
For WinForms programming, the book that has proved itself most useful to me is Windows Forms 2.0 Programming. If there isn't a single book that has everything you're looking for, I think this book would be part of the collection comprising the next best thing.
