I took a shot at new (to me) certification exam for BizTalk 2010. I was able to pass it without any preparation just based on the experience. That does not mean this exam is a very simple one. Comparing to previous (2006 R2) it covers some new areas (like WCF) and has some demanding questions and situation to think about. But the most challenging factor is broad feature coverage. Overall, the impression that if BizTalk continues to grow in scope it’s better to create separate exams for core functionality and extended features (like EDI, RFID, LOB adapters) because it’s really hard to cover vast array of BizTalk capabilities. As far as required knowledge and questions allocation I think Microsoft description is on target. There were definitely more questions on deployment, configuration and administration aspects comparing to previous exam. WCF and WCF based adapters now play big role and this topic was covered well too. Extended functionality is claimed at 13% of the exam, I felt there were plenty of RFID questions but not many EDI, that’s why I thought it’d be useful to split exam into two to cover all of them equally. BRE is still there and good, cause it’s usually not very known/loved feature of the package. At the and, for those who plan to get certified, my advice would be to know all those areas of BizTalk for guaranteed passing: messaging and orchestrations, core adapters, routing, patterns; development of all artifacts and orchestrations; debugging and exceptions handling; packaging, deployment, tracking and administration; WCF bindings and adapters; BAM, BRE, RFID, EDI, etc. You may get by not knowing one smaller non-essential part (like I did with RFID, for example). In such case you better know all other areas very well to cover for the weak spot. If there more than one whiteouts in the knowledge it’s good idea to study and prepare: MSDN, blogs, virtual labs and good VM to play with can help when experience is not enough. So best wishes and good skill to you in passing this certification!
When I install ubuntu 12.04 beta 2 using wubi ,
first it extracts the files
and then asks to reboot to complete the installation.
But when I reboot the machine the installation hangs
and there is a message

but when I git status for a project I still end up getting the .idea files when I start using rubyMine.
So my git status still shows this:
# modified: .idea/dataSources.xml

I have run git config --global core.excludesfile ~/.gitignore_global bvut it didn't help.
I installed Ubuntu 12.04.1 in a desktop with the following specs:
CPU: Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz
Motherboard: Intel DH67B
However the monitor is not identified (Monitor: Unknown) such that maximum resolution is 1024x768. This occurs with Samsung Syncmaster 2033 (resolution 1900x600), and is the same with ViewSonic VX2453mh-LED (resolution 1920x1080). I'd be very grateful if anyone could give me a suggestion as to how to fix the resolution.

I am currently undecided between which of the following web algorithms book to buy:
1) Algorithms of the Intelligent web by Marmanis
2) Collective Intelligence by Alag
Both feature code in Java; Marmanis' book delves deeper into the core algorithms while Alag's book discusses more APIs including WEKA. I have already read Programming Collective Intelligence by Segaran and enjoyed it.
Any comments on these books or any other recommendations are welcome.
I am a bit of a noob when it comes to Linux. I have a basic understanding but struggle with the more complex things. I am using a Dell XPS 17 (L207X) which has a core i7 processor and Nvidia GT555M hybrid card and cannot get a successful installation of any Ubuntu distro from 11.Xx upwards.
Could anyone offer any help / advice / step by step instructions to help me get a successful installation of at least 11.10 as that is the distro I was using on my old laptop?
Another book that I re-read while travelling last week was Fast Track to MDX . I still think that it's the best book that I've seen for introducing the core concepts of MDX. SolidQ colleague Mark Whitehorn, along with Mosha Pasumansky and Robert Zare do an amazing job of building MDX knowledge throughout the book. I had dinner with Mark in London a few years back and I was pestering him to update this book. The biggest limitation of the book is that it was written for SQL Server 2000 Analysis Services,...(read more)

Please suggest books for procedural programming. I need to know the core principles/patterns of procedural programming. So it doesn't matter if the book using any language to convey the procedural programming principles, be it pure C or others languages.
Nowadays it is difficult to find ones. Even google and amazon searches didn't give me a satisfactory books. You may vote to close this question but please recommend books in comment section.
In Ubuntu 12.04 I can only reload my uwsgi app once, after this reload and force-reload fail. This appears to be because after the first reload the process names change from uwsgi to uwsgi-core, and the reload script looks for uwsgi processes with specific pids.
I'm not sure if this is just a bug, and if so is there somewhere sensible for me to report it?
Otherwise is there something I could be doing wrong to cause this?
My graphic on ubuntu 12.10 does not work as well as on 12.04.
After upgrade I installed driver
sudo apt-add-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update
sudo apt-get install nvidia-current
for my Nvidia 450 GTS graphics card.
But sometimes I see slight lag on my videos played in VLC player, some of desktop and window effects are lagging, sometimes I can see an indescribable souce of pixels on my screen at the start of ubuntu and so on.
I feel difference between 12.04 and 12.10 in favour of former version.
Does anyone know whats wrong or what I am missing?

The cursor sometimes goes wild, I get random clicks, the windows are resizing, the cursor disappears. In the worst case, clicks and keyboards are disabled.
I've tried the solution given on doc.ubuntu-fr.org and add tu grub :
i8042.nomux=1 i8042.reset=1 in GRUB_CMDLINE_LINUX_DEFAULT
But it didn't work
What can I do ?
Graphic card : Geforce GTX460M.
Ubuntu : 11.10 (64 bits).
Laptop Asus G73sw
Interface : Unity (since 11.10) - didn't get this problem with Gnome before.
Complement: when a window is resizing, it gets drag-boxes at every corner, center of sides and center of the window. It looks like my touchpad sends random info, or like a "ghost" touchscreen.

I have a question, it's about why programmers seems to love concurrency and multi-threaded programs in general.
I'm considering 2 main approaches here:
an async approach basically based on signals, or just an async approach as called by many papers and languages like the new C# 5.0 for example, and a "companion thread" that manages the policy of your pipeline
a concurrent approach or multi-threading approach
I will just say that I'm thinking about the hardware here and the worst case scenario, and I have tested this 2 paradigms myself, the async paradigm is a winner at the point that I don't get why people 90% of the time talk about multi-threading when they want to speed up things or make a good use of their resources.
I have tested multi-threaded programs and async program on an old machine with an Intel quad-core that doesn't offer a memory controller inside the CPU, the memory is managed entirely by the motherboard, well in this case performances are horrible with a multi-threaded application, even a relatively low number of threads like 3-4-5 can be a problem, the application is unresponsive and is just slow and unpleasant.
A good async approach is, on the other hand, probably not faster but it's not worst either, my application just waits for the result and doesn't hangs, it's responsive and there is a much better scaling going on.
I have also discovered that a context change in the threading world it's not that cheap in real world scenario, it's in fact quite expensive especially when you have more than 2 threads that need to cycle and swap among each other to be computed.
On modern CPUs the situation it's not really that different, the memory controller it's integrated but my point is that an x86 CPUs is basically a serial machine and the memory controller works the same way as with the old machine with an external memory controller on the motherboard. The context switch is still a relevant cost in my application and the fact that the memory controller it's integrated or that the newer CPU have more than 2 core it's not bargain for me.
For what i have experienced the concurrent approach is good in theory but not that good in practice, with the memory model imposed by the hardware, it's hard to make a good use of this paradigm, also it introduces a lot of issues ranging from the use of my data structures to the join of multiple threads.
Also both paradigms do not offer any security abut when the task or the job will be done in a certain point in time, making them really similar from a functional point of view.
According to the X86 memory model, why the majority of people suggest to use concurrency with C++ and not just an async approach ? Also why not considering the worst case scenario of a computer where the context switch is probably more expensive than the computation itself ?
I am really excited to see lot of new news around BizTalk in TechEd 2012. I was recently watching the session presented by Sriram and Rajesh on “Application Integration Futures: The Road Map and What's Next on Windows Azure”. It was great session and lot of interesting stuff about the feature updates for BizTalk and Azure integration. I have highlighted them below, definitely customers who haven’t started using Microsoft BizTalk ESB Toolkit should start using them which is going to be part of the core BizTalk product in future release, which is cool…

Use Azure to provision BizTalk environment for test environment / development. Later move to On-premises or build a Hybrid cloud approach.
Eliminate HW procurement for BizTalk environment for testing / demos / development etc.
Enable to create BizTalk farm easily and remove/add more servers as needed.
EAI Service:
EAI Bridge
Protocol transformation
Message Transformation
Running custom code
Message Enrichment

LOB Applications On-premises
Application On-premises
Connectivity to
Applications in the cloud
Queues/ Topics
Ftp
Devices
Web Services
Bridge can be customized based on the service needs to provide different capabilities needed as part of the bridge. Look at the sample for EDI bridge for EDI service sample. Also with Tracking enabled through the portal.
http://msdn.microsoft.com/en-us/library/windowsazure/hh674490
Adapters:
Service Bus Messaging adapter - New adapter added.
WebHttp adapter - For REST services.
NetTcpRelay adapter - New adapter added.
I will start posting more and once I start playing with this…
Ethical questions come up more and more in the news, and can be core to a software developers' life. On several occasions this year I was asked for advice that amounts to answering ethical questions, in a computer programming context, and I was surprised to see how much fretting and trouble questions which I consider trivial can lead to.
Are there any courses or programs specializing in teaching what is expected of an ethical programmer? Has anyone put together a formal curriculum anywhere?
