I want to learn virtualization basics inside out. All the books in top results of amazon are too superficial and are only meant for managers, ie people who only need to have a vague idea of what it is all about. I want to understand it inside out and from the basics.
Please DONT suggest virtualization for dummies. That book is superficial.
I want the core concepts only, that is how virtuazlization works behind the scenes. I am NOT looking for books to set up any virtual machine software like vmware, hyper-v etc.
As far as I know, there are no books covering this subject (how a VMM actually works).
The way I gained my knowledge was by reading whitepapers and research-papers, and once I was past that, looking at QEmu/KVM and VirtualBox.
A nice overview can be found here:
http://www.vmware.com/files/pdf/VMware_paravirtualization.pdf
A deeper paper (often refered to in other paper) can be found here:
https://www.vmware.com/pdf/asplos235_adams.pdf
After reading those, you should have gotten a nice "vocabulary" about VMMs, and you should be able to google your way to other papers by using VMM specific vocabulary such as "Hardware assisted VMM page faults", and so forth.

I'm looking into developing a title for the next PlayStation (to be unveiled on Feb 20th) and PSVita to be distributed on the PlayStation Network. I know how to get in contact with Sony and all, but I haven't submitted my application yet (even though I have a pretty good portfolio) and I was hoping to use Sony's own PhyreEngine for development of the game.
I was wondering if any of you guys knew what programming language the engine uses or is based on? As I want to be well prepared for production of the game. Also, if there's anyone who reads this and has developed a PSN game before, do you have a rough outline of how much it'd cost? (Dev Kits, SDKs, licenses etc.)
Thanks
Harry
PhyreEngine itself is written in C++. The tools are primarily C#.
Can't tell you anything about costs in general, you'd have to get in touch through official channels for that info. PhyreEngine itself is free to any licensed developer though, it's just part of the SDK.
(disclosure - PhyreEngine is my project)
PhyreEngine is based on C++, with a possibility of a few low level C libraries.
This information is from a post in this forum: http://www.3dbuzz.com/forum/threads/181890-What-runs-on-a-PS3/page2, about halfway down the page. A poster asked the same questions you did.
Hope this helps!
I am currently working with CAVE systems and I'm looking into hooking up a pre-exisiting game engine in one. I know this is possible through Unity and the Unreal Engine as there is already research out there showcasing that it has been done.
Right now, I have not decided upon one game engine to use and I'm currently looking around and researching if it is possible with the likes of CryEngine and Valve's Source Engine. The one issue that I am going to face, however, is getting the image to correctly render across all four of the monitors / screens.
Thusly, as a result I have two questions:
1.Does anyone know of any good research / books on distrubuted rendering? It doesn't need to be specificly for games, just the topic in general would be very useful
2.Does anyone know if other developers have managed to get Source and the CryEngine to run in a CAVE system? Through all my research I haven't been able to find anything on this, but then my google skills aren't the greatest.
If anyone could spare the time to answer these questions, I'd be extremely greatful.
Thanks.

I work on a project known as the Security Development Lifecycle (SDL) project at Microsoft (http://microsoft.com/sdl) - in short it's a set of practices that must be used by product groups before they ship products to help improve security.
Over the last couple of years, we have published a great deal of SDL documentation, as customers ask for more information about what we're doing.
But what I'd like to know is:
What are you doing within your organization to help improve the security of your product?
What works? What doesn't work?
How did you get management to agree to this work?
Thanks.
Honestly, Reading your book was a good start. :-)
Responding to your questions:
Crypto is a hobby of mine that I sometimes blog about (e.g. on TLS and AES). After writing my own implementation of AES, I learned enough to know beyond a reasonable doubt that I should never use my own implementation but rather use the ones written by the CryptoAPI and OpenSSL guys.
Code reviews where people that are good at security issues are marked as required.
Having a class on-site with labs to raise awareness of issues mentioned in your book as well internal mailing lists discussing new issues.
Several folks listen to the Security Now podcast to keep current on what types of issues are out there and what is getting attacked. This indirectly affects design.
Except for an on-site course and buying the code review tool, none of these require management approval.
I'm an indie mac developer, but also a platform security evangelist: I'm the author of Pro Cocoa Application Security published by Wrox. In that book I champion the secure dev technique I use myself: it's based on the Swiderski and Snyder threat modeling, but with two changes. I make it lighter weight by considering which entry points access which assets without using DFDs. I also put more focus on identifying users and misusers, which I think makes it more applicable to shrinkwrap software.
As far as tool support is concerned, I use the Xcode static analyzer (based on clang), but have found it doesn't detect some common vulnerabilities. I did file bugs though :-). I also always use the gcc _FORTIFY_SOURCE macro. There aren't good Mac risk analysis tools but I'm working on that... ;-)
I've spoken on security to Mac devs at conferences and in podcasts and gotten plenty of feedback, if you want me to clarify anything I've said or are interested in the community feedback please ask in comments. Private questions are welcome to (though I'd prefer to stay on the forum): iamleeg at securemacprogramming dot

We think before we code. Strangely enough, it avoids many bugs, including those which are exploitable by adverse parties and henceforth known as "security holes".
Part of the trick is not letting anyone near a keyboard unless he has a solid amount of experience and expertise.
This is not 100% programming related. But I think this is somewhat useful because it is addressing a minority in the SO community.
Microcontroller programming is one of the interesting areas in programming. I saw some topic here requesting the Resources for starting / learning / discussing about PICs.
Example topic
Since I have plenty of knowledge and experiences in this area I am thinking of publishing some resources that helps a novice to learn them from the basics. It will be not just a theoretical publication and will be based on example projects. I hope to start this over a new blog + forum so the users can dynamically interact with each other. I came in to this decision because I found very small amount of Sites that a novice can start learning and work collaboratively.
What do you guys think about this? Have you ever experienced such difficulty? Do you think you can get some use of that? What are the things you like to see on the site?
I would be thankful If you are not going to close this as NPR. I just want to do some service to other microcontroller lovers :)
There are already a few such tutorials on the net (e.g. this one from SparkFun), another one might be a valuable addition, but only if it is better or different in some way.
What will you offer that is a real improvement?
Some suggestions:
Don't assume I have windows
Have some side discussion of difference between various MCU and/or supporting electronics. Discuss some of the trade offs
You'll need a pretty general tutorial to suck people in, but the real value added might be in a specialized focus after the start
Build up to something useful and/or geeky cool
A unit on component integration (i.e. I can buy a Polar style heart rate receiver, and a MCU and a USB interface. How do I get them talking to each other so I can build an exercise data logger?)
What every you do, I'm looking forward to it (just learning embedded stuff in my spare time...).
There are the excellent tutorials at www.mikrocontroller.net, but they are in German.
If you could create something similar for an English speaking community, that would be great.
Yes! The more resources out there for helping with embedded software (microcontroller programming) the better.
It can be quite daunting to start with, especially if you've only written software for PCs or similar in the past. There are lot more constraints (e.g. on RAM and code space), and a whole load of things you need to know that don't apply to non-embedded software.
As others have mentioned here, there a number of websites that cover different aspects of this; some others are OnARM, for ARM processors, the related STM32 Circle, and Jack Ganssle's articles on his website and on Embedded.com.
Though embedded systems are an enormous market (just think how many such devices there are in your house, or in your car), my impression is that there is a lot less coverage of the subject on the web - and on Stack Overflow - than for non-embedded.
So, I look forward to seeing the fruits of your labour!
Something else that's worth to take into account when targeting beginners, is to directly provide pointers to useful resources, such as suitable simulators/emulators, or even addresses/webpages where you can easily order a starter kit or even free samples of some chips.
For example, most semiconductor manufacturers provide free samples of their products, e.g. see microchip.com or atmel.com.
Ideally, an introductory course would be based on working with such a hardware simulator or emulator in the beginning, so that the project and all relevant experience may directly map onto a real device once the beginner is interested in moving his work onto a real chip, providing pointers to freely available resources, or very affordable starter kits can be very useful.
This would ensure that beginners can get started as easily and cheaply as possible.
Maybe for the different ARM7 and CortexM3...?
Here everyone asumes there is a lot of information, but it is spread all over the net and without any red line what so ever...
But if you take AVR there is quite a lot of stuff over at http://www.avrfreaks.net, and I guess that PIC has quite a lot as well.
I have written many such examples myself but they are scattered and not organised and probably rarely read (one time the folks at avrfreaks borrowed something). StackOverflow might curb this but SO could in theory be used. Ask a question about boot code for an arm whatsit, then answer your own question with example code and text on how and why it works. The SO tags would be nice in that you could do a search on "boot" "arm" "embedded" and then one on "boot" "avr" "embedded", etc and get similar example programs for different platforms.
Personally I would go more in the direction of creating an example archive of complete programs for specific microcontroller versions (in typical uses), instead of making yet another "general" tutorial. E.g. one of microcontroller x/y that enables a serial port, one that configures a few digital outputs (setting TRIS and friends), how to set up common frequency/oscillator options etc.
When I started with PIC, (very short PIC16, then PIC18 then 24F and now dspic), one of the main problems is that all the examples are either only fragments or describing very general principles.
A tutorial is no good, if it takes more skills to get the examples actually working than the tutorial teaches.
I usually couldn't find one single complete program for exactly my controller, or even for the slightly wider group (that only vary in number of pins and memory/flash).
The initial program was always the problem, but sometimes later I had the same problem (initializing a certain peripheral) all over again (e.g. the encoder) It is specially frustrating if is the first run of a new micro controller line, and you might not be 100% sure of your hardware.
Unfortunately that takes some coordination, from a forum, an user group or so, since nobody has all devices, and all variants to wire them up (e.g. different oscillator options).
I posted this community wiki in the hopes of creating a thread of expertise. My question is thus ... "Where do the experts go to learn about the newest coding techniques?".
I'm basically looking for the leading/bleeding edge of architecture, design, development and theory.
I know conferences and trade shows are probably the best venues to see the latest and greatest, but for those on a limited budget (of both time and money) such as myself, I'm looking for websites that I can read in the evenings that will keep me current on what's new in the world.
I program mostly in C# but the websites need not be geared towards C#.

The ondemand(previously recorded) webcasts from Microsoft are normally really good, but it's a painful number of clicks to actually get to the point where you can download the file, and sometimes you find that it is not available.
Also sometimes you can find a .NET User Group locally that will have speakers/sessions occasionally. These are also great ways to network and find out what kind of work is going on in your area.
Books, books, books! Good books are written by subject matter expects, involve input from many sources, are peer reviewed, well structured and go orders of magnitude deeper than trade shows, and most online material. When you buy a book, you get the experience of an expert for a very reasonable price.
NDepend documentation comes with two white books and also online blog posts and articles concerning the architecture for large .NET application:
Partitioning code base through .NET assemblies and Visual Studio projects (8 pages)

I never get to go to PDC, but I do love to watch the videos.
As a previous post mentioned the MS PDC videos are on online. Same with Mix which has good MS Web development related content. Also, for general MS videos there is Channel 9, it's not all technical content, but it's worth searching if you are looking for something in particular.
Someone already mentioned blogs, here are a few more:
Scott Hansleman - lots of stuff on there, a lot of ASP, MVC stuff.
Phil Haack - another good MVC guy.
Rob Connery - again a lot of focus on MVC.
ScottGu - according to his blog he "builds a few products for Microsoft", which has to be the understatment of the year - he is in charge of ASP, IIS, SIlverlight and much more besides at MS.
Check out Sharp Architecture, it's very promising.
I've collected several RSS feeds that I regularly to stay up-to-date on .NET and Agile. If you like I can share the list with you. It contains most of the stuff already mentioned here.
