• How mod_cache working with "must-revalidate" and "max-age"?

  - by Dmitriy Sosunov

  Quick question before I will explain my flow: ?an mod_cache perform revalidate with if-none-match only if max-age is expired in case if it configured in reverse proxy mode? My goal is to reduce a number of revalidation requests to our the origin server. For instance: The first request goes to the origin server and then mod_cache save a response in to the cache according to header cache-control: max-age. And only when max-age is expired then mod_cache will revalidate with if-none-match. Currently, mod_cache revalidate each request, regardless that max-age is defined or not. My configuration of Apache 2.4.3 (Windows), on linux I see the same behavior that I will show below. ServerName proxy.lo ProxyRequests Off ProxyPreserveHost Off Header set Vary "Accept, Content-Type, Content-Encoding, Accept-Language" RequestHeader set X-Forwarded-Proto "http" # modify header for user agent's Header set Cache-Control "private, no-cache, no-store, no-transform" CacheQuickHandler off CacheDefaultExpire 300 # the origin server do not provide last-modified CacheIgnoreNoLastMod On CacheIgnoreCacheControl On # the origin server define cache-control: private, no-store only for user agents # Therefore, I would like ignore those headers on the proxy server. CacheStorePrivate On CacheStoreNoStore On CacheEnable disk / CacheRoot "C:/Apache.Cache" CacheDirLevels 5 CacheDirLength 4 CacheMinExpire 15 CacheDetailHeader on CacheHeader on KeepAlive Off ProxyPass / http://origin.lo/ ProxyPassReverse / http://origin.lo/ Also, I have turned on debug log level to see how mod_cache handles a content for caching: I provided this to show that mod_proxy always decides that a content isn't fresh. Why?I provided this to show that mod_proxy always decide that a content isn't fresh. Why? max-age was provided (see below).

Is't right? Let's check it:) Within 30 sec, the Google Chrome didn't perform any requests to the origin server to revalidate a request and has return the response from local cache. When max-age is expired, the Google Chrome perform a request to revalidate: GET http://origin.lo/testpage HTTP/1.1 Host: origin.lo Connection: keep-alive Cache-Control: max-age=0 User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.4 (KHTML, like Gecko) Chrome/22.0.1229.94 Safari/537.4 Accept: application/xml If-None-Match: "7cf651e2-176f-4ac1-808e-0e0c17cfd0a2" Accept-Encoding: gzip,deflate,sdch Accept-Language: en-US,en;q=0.8 Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3 and response: HTTP/1.1 304 Not Modified Cache-Control: must-revalidate, proxy-revalidate, max-age=30 ETag: "7cf651e2-176f-4ac1-808e-0e0c17cfd0a2" Server: Microsoft-IIS/7.5 X-AspNet-Version: 4.0.30319 X-Powered-By: ASP.NET Date: Sun, 04 Nov 2012 10:16:20 GMT As you can see, all works as expected.

N.B. Apache 2.4.3 Thanks, I would be grateful for any help.

• Apache2 graceful restart stops proxying requests to passenger

  - by Rob

  Issue with apache mod proxy, it stops proxying requests after a graceful restart but not all the time. It seems to happen only on a Sunday when a graceful restart is triggered by logrotate. [Sun Sep 9 05:25:06 2012] [notice] SIGUSR1 received.

It's worth noting that the destination is just another vhost on the same apache instance, but the vhost (http://api.myservice.org) is serving passenger (mod_rails) I was thinking that maybe there's some startup issues with the passenger workers not being ready during a graceful restart?

• Deploying Django on EC2 using Bitnami Djangostack: WSGI script cannot be loadded

  - by Arman

  I've been struggling to deploy Django application on Amazon EC2 using Bitnami Djangostack for the last couple of days. When I go to http://dewey.io I see the default bitnami page (/opt/bitnami/apache2/htdocs/index.html), however, when I open http://dewey.io/portnoy, I get 'Internal Server Error'. But it's known that if mod_wsgi is setup correctly, the DocumentRoot value from httpd.conf is ignored, thus, I should see my Django application when accessing http://dewey.io. Essentially, the main error is this - 'Target WSGI script cannot be loaded as Python module'. Two questions: 1) any ideas how to fix these mod_wsgi errors (the Apache logs are below)? 2) how to disable the default /opt/bitnami/apache2/htdocs/index.html page and show my homepage from django application when accessing http://dewey.io? Thank you in advance! The details On my EC2 instance I"m running 64-bit Ubuntu 12.04 with DjangoStack 1.4-1.

• Bitlocker and SQL Server (2012)

  - by cdonner

  I just turned on Bitlocker on my development laptop for the first time (Windows 8.1) and encrypted both SSDs. When I started SQL Server Enterprise Manager, it could not connect to the default instance on the local machine. Does this not work? I have been googling for an hour and only found anecdotal evidence, but no solid information. Just to clarify - I am not interested in encrypting a database. I want to run SQL Server on a machine with an encrypted drive.

• Server 2012, Jumbo Frames - should I expect problems?

  - by TomTom

  Ok, this sound might stupid - but is there any negative on just enabling jumbo frames in practice? From what I understand: Any switch or ethernet adapter that sees a jumbo frame it can not handle will just drop it. TCP is not a problem as max frame size is negotiated in the setinuo phase. UCP is a theoretical problem as a server may just send a LARGE UDP packet that gets dropped on the way. Practically though, as UDP is packet based, I do not really think any software WOULD send a UDP packet larger than 1500 bytes net without app level configuration changes - at least this is how I do my programming, as it is quite hard to get a decent MTU size for that without testing yourself, so you fall back in programming to max 1500 packets. The network in question is a standard small business network - we upgraded now from a non managed 24 port switch to a 52 port switch with 4 10g ports (netgear - quite cheap) and will mov a file server to 10g for also ISCSI serving. All my equipment on the Ethernet level can handle minimum 9000 bytes and due to local firewalls I really want to get packets larger (less firewall processing), but the network is also NAT'ed to the internet. On top, different machines move around (download) large files (multi gigabyte area) quite often for processing. The question is - can I expect problems when I just enable jumbo frames? Again, this is not totally ignorance - I just don't see programs sending more than 1500 byte UDP packets (if that is a practical problem please tell me) and for TCP the MTU is negotiated anyway. if there is a problem I can move to a dedicated VLAN, but this has it's own shares of problems as basically most workstations must then be on both VLAN's.

• Start jade via batch script as service on windows server 2012 amazon ec2 instance

  - by E. Lüders

  I would like to start the Jade agent platform with a batch script on an windows server ec2 instance as a service. The reason for this is, that I want to start jade automatically at system startup. For creating the service I use nssm. However so far its working fine and the service is created. When I want to start the service I get an error message: Windows could not start the NAME service on Local Computer. The service did not return an error... My batch file contains only one line: java jade.Boot -platform-id P%random% If i execute the script via cmd it works fine. Anybody got an idea why this is not working if I start the batch script as a service?

• Symantec Backup exec 2012 for SBS - moving data to offsite drives

  - by Will Lennard

  Can anyone advise how best to run the following strategy, or even if it is possible/sensible strategy? I am looking to backup an SBS server using BE2012 where the data is backed up on a weekly full backup, with subsequent daily incrementals till the end of the week, a fresh full backup will then be taken the next weekend, and the cycle repeats for 4 weeks, thus 4 full backups with incrementals. This months worth of backups will then be moved off to an offsite store via USB drive for safe keeping. Is this viable, sensible, or am i just a bit crazy? All ideas are welcome.

• Can Ping but Cannot Telnet directly to SQL Server 2012 Cluster Nodes

  - by tresstylez

  We have a monitoring tool (Solarwinds Orion) that needs to connect to a 2-node failover SQL Server Cluster. For reasons outside of our control -- we cannot monitor the CLUSTER IP directly at this time, so we have fallen back to monitoring each cluster node IP directly. This is not working. Upon troubleshooting, we tried to test that the cluster node was listening on the proper (fixed) port by using telnet to the cluster node IP/port -- and the telnet failed. However, telnet'ing to the Cluster IP/Port was SUCCESSFUL! Each node has its own IP. Each node is listening on the identical FIXED port. Each node has Dynamic Ports disabled. Each node can be PINGED successfully from the monitoring tool. Windows Firewall is DISABLED. How can I troubleshoot why I cannot telnet to the listening port on the cluster nodes?

• No compatibility tab for Devenv.exe (VS 2010 and VS 2012) on Windows 8

  - by mkinkade

  I've tried checking the "Run as Administrator" on the shortcut, but that doesn't always seem to work, like when I open the solution through the jumplist. I browsed to the devenv.exe file, but when I open the properties for the file the Compatibility tab is not there. It is there for other executables in the same directory. Does anyone know how I can get the tab back so that I can set the Run as Administrator open on the executable?

• Microsoft Deployment Toolkit 2012 Error

  - by Jacob Schaer

  I just started with MDT2012 recently in hopes of eventually getting away with using Ghost to deploy all of our department computers. When I test deploy in VirtualBox, it deploys the OS properly, but stops because of a network driver failure (it gets the "could not allocate resources" issue). On physical hardware (Latitude E6500, Optiplex 980, and an older Latitude) it gets through the multicast and stops immediately after with: "Setup was unable to create a new system partition or locate an existing system partition. See the Setup log files for more information" I've looked at the logs and never see anything really of note. Originally I was using DriverPacks from DriverPacks.net, but thinking it was a driver issue, I switched over to using Dell's cab driver packs. Still the same issue. I check and it did the HDD is all fine - it was properly partitioned, set to bootable, and was loaded with all the proper OS installer files. I'm using a flash drive to do the install - when I make changes to the deployment share I rebuild and copy the ISO to the drive, then use YUMI multiboot to start the ISO (probably irrelevant).

• HP DL380 G3 2U For Basic Web Server in 2012

  - by ryandlf

  I have an opportunity to pick up a used HP DL380 G3 2U for $100. I'm looking for a basic entry level web server that I can host a small - medium size website on and more or less learn the ins and outs of running my own web server before I bite the bullet and spend a couple grand on a server. The specs are: Dual (2) Intel Xeon 2.4GHz 400MHz 512KB Cache 4GB PC2100 ECC Registered Memory 6 x 72GB 10K U320 SCSI Hard Drives Smart Array 5i RAID Controller Redundant Power Supplies DVD/Floppy, Dual Intel GB NIC's, USB Or would I be better off spending a couple hundred bucks on something like: this new HP Seems like the only major difference is SATA and a bit of storage, but I will likely be implementing a separate storage system of some sort anyways. I guess it also wouldn't hurt to mention that I plan on running a linux server distro, so would the hardware be likely to support linux with a system that is 4 generations old? I don't mind spending a couple hundred extra dollars if its a better solution, but as mentioned previously I am simple looking for a server to learn on and probably use for a year or so while I put together a small - medium size website.

• Windows 2012 Master & Ubuntu Bind 9 Slave & SOA

  - by RecentCoin

  I'm kinda like the maid... I don't do Windows. But thanks to new things we're implementing, I'm now attempting replicating a single zone from our AD cluster. We had this working just fine but someone had to "adjust" it. That broke the replication completely. We've gotten that restarted but now a different DC is showing as the SOA. Does it matter which of the domain controllers is listed as the SOA? The contents of the zone file appear to be correct. Part of me says "Good enough. Leave it be." but the rest of me doesn't want a 3AM phone call. So does anyone know if it matters which DC is listed as the SOA?

• The reasons to upgrade from Delphi 2009

  - by Serg

  I have made the question "community wiki" - it is subjective. I have upgraded to Delphi 2009 because of unicode support. I have found the anonymous methods a very interesting and useful language feature, I can't say the same about generics. The generics seemed important for me before the upgrade to Delphi 2009, but I have never used them and probably will never use. As for Delphi 2010, I don't need the attributes and I don't like the whole idea of extended RTTI - that is why Delphi 2009 is better for me. Sometimes I hit one or other annoying bug in Delphi 2009 IDE, but they are not critical and I can live with them. I have no plans to develop software for Mac or Linux. Sure sometime I will need 64-bit support, so I think about upgrading to Delphi 2012. Are where any more reasons that can force me to upgrade from Delphi 2009?

• VS2012 equivalent of Eclipse's default Ctrl-Shift-O?

  - by x3chaos

  I'm used to Java (in Eclipse), which has its import statements, but I'm writing a DLL in Visual C# (in Visual Studio 2012), which has its using statements. I'm used to Eclipse's default keyboard shortcut Ctrl-Shift-O, which updates the list of import statements in the Java perspective, deleting unused imports and adding necessary imports found on the build path. Is there an equivalent operation in VS2012 with VC#? I've just been selecting the word, opening the Office-style popup, and added the "using" statement that way, but it conflicts with my workflow (read: I'm lazy and I like having my shortcuts).

• vb.net auto detect dependency files for wix 3.7

  - by Khan

  I am in the process of learning WIX all thanks to MS for removing such a nice tool (vdproj) from the latest versions of visual studio. I have come to know that I can add my files (and dlls) to distribute in WIX using that tag. It is OK. But in vdproj it was very easy to add all files. I just need to right click in file view, and select 'add project output'. This was enough to add dozen of files that were required for my application. In visual studio 2012, and using WIX 3.7, what options do I have to automatically list all those dlls that are required by my application?

• Waiting for a background operation to complete

  - by JohnHenry

  I have been suffering from the all too common 'Waiting for a background operation to complete...' message in Visual Studio 2012 (Professional) for a while now but it has been fairly sporadic. Lately though, I am really struggling to use Visual Studio as pretty much whenever i try and do anything with any Razor views (mostly clicking to move the cursor) visual studio hangs and the above message appears for about a minute at a time. (If when its finished doing stuff i then click in the view again, the process repeats, and repeats, and repeats.....) I have searched high and low, and read loads of articles regarding this and peoples suggestions and tried changing indentation settings, resetting settings, etc but none have worked. Has anyone come across something else that may work as this is seriously impeding my ability to use visual studio and sadly provoking much cursing.

• How to Create C++ Project Filter/Folder in Visual Studio?

  - by BSalita

  Using Visual Studio 2012, I'd like to create a C++ project folder called "Include Files", which has the same characteristics as the well known folder "Header Files". That is, the files in Include Files have a cpi extenson and will be parsed out for use with InteliSense, and also can be precompiled. I'm able to create the folder but files within it aren't parsed. I've tried setting the type to C++ Header file. Nothing seems to work. The files work fine when given a hpp extension and put into Header Files folder.

• Reasons for sticking with TEXT, NTEXT and IMAGE instead of (N)VARCHAR(max) and VARBINARY(max)

  - by John Assymptoth

  TEXT, NTEXT and IMAGE have been deprecated a long time ago and will, eventually, be removed from SQL Server. However, they are not going to be discontinued right away, not even in the next version of SQL Server, so it's not convenient for my enterprise to transform thousands of columns right away, even if it is using SQL Server 2012. What arguments can I use to postpone this migration? I know there are some advantages in using the new types. But I'm strictly looking for reasons not to migrate my data that is already functioning pretty well in the old types.

• Do Portable Class Libraries work with .net 3.5?

  - by Eric

  I am running Windows 8 and have both Visual Studio 2010 Ultimate w/sp1 and Visual Studio 2012 Ultimate and I am trying to create a Portable Class Library that supports .net 3.5 and greater. When I first try to create a PCL I get a screen like this: I noticed that .net 3.5 is not in the list so I clicked on "Install additional frameworks" and found a Targeting Pack for version 3.5. But when I download and run "dotnetfx35setup.exe" nothing happens. And when I go back into VS and try to create a new Portable Class Library, it lists the same target frameworks as before. I have also turned on the Windows Features for .NET Framework 3.5 and am now out of ideas. Here is a screen shot in case I missed something else. Thanks,

• SQL SERVER – Thinking about Deprecated, Discontinued Features and Breaking Changes while Upgrading to SQL Server 2012 – Guest Post by Nakul Vachhrajani

  - by pinaldave

  Nakul Vachhrajani is a Technical Specialist and systems development professional with iGATE having a total IT experience of more than 7 years. Nakul is an active blogger with BeyondRelational.com (150+ blogs), and can also be found on forums at SQLServerCentral and BeyondRelational.com. Nakul has also been a guest columnist for SQLAuthority.com and SQLServerCentral.com. Nakul presented a webcast on the “Underappreciated Features of Microsoft SQL Server” at the Microsoft Virtual Tech Days Exclusive Webcast series (May 02-06, 2011) on May 06, 2011. He is also the author of a research paper on Database upgrade methodologies, which was published in a CSI journal, published nationwide. In addition to his passion about SQL Server, Nakul also contributes to the academia out of personal interest. He visits various colleges and universities as an external faculty to judge project activities being carried out by the students. Disclaimer: The opinions expressed herein are his own personal opinions and do not represent his employer’s view in anyway. Blog | LinkedIn | Twitter | Google+ Let us hear the thoughts of Nakul in first person - Those who have been following my blogs would be aware that I am recently running a series on the database engine features that have been deprecated in Microsoft SQL Server 2012. Based on the response that I have received, I was quite surprised to know that most of the audience found these to be breaking changes, when in fact, they were not! It was then that I decided to write a little piece on how to plan your database upgrade such that it works with the next version of Microsoft SQL Server. Please note that the recommendations made in this article are high-level markers and are intended to help you think over the specific steps that you would need to take to upgrade your database. Refer the documentation – Understand the terms Change is the only constant in this world. Therefore, whenever customer requirements, newer architectures and designs require software vendors to make a change to the keywords, functions, etc; they ensure that they provide their end users sufficient time to migrate over to the new standards before dropping off the old ones. Microsoft does that too with it’s Microsoft SQL Server product. Whenever a new SQL Server release is announced, it comes with a list of the following features: Breaking changes These are changes that would break your currently running applications, scripts or functionalities that are based on earlier version of Microsoft SQL Server These are mostly features whose behavior has been changed keeping in mind the newer architectures and designs Lesson: These are the changes that you need to be most worried about! Discontinued features These features are no longer available in the associated version of Microsoft SQL Server These features used to be “deprecated” in the prior release Lesson: Without these changes, your database would not be compliant/may not work with the version of Microsoft SQL Server under consideration Deprecated features These features are those that are still available in the current version of Microsoft SQL Server, but are scheduled for removal in a future version. These may be removed in either the next version or any other future version of Microsoft SQL Server The features listed for deprecation will compose the list of discontinued features in the next version of SQL Server Lesson: Plan to make necessary changes required to remove/replace usage of the deprecated features with the latest recommended replacements Once a feature appears on the list, it moves from bottom to the top, i.e. it is first marked as “Deprecated” and then “Discontinued”. We know of “Breaking change” comes later on in the product life cycle. What this means is that if you want to know what features would not work with SQL Server 2012 (and you are currently using SQL Server 2008 R2), you need to refer the list of breaking changes and discontinued features in SQL Server 2012. Use the tools! There are a lot of tools and technologies around us, but it is rarely that I find teams using these tools religiously and to the best of their potential. Below are the top two tools, from Microsoft, that I use every time I plan a database upgrade. The SQL Server Upgrade Advisor Ever since SQL Server 2005 was announced, Microsoft provides a small, very light-weight tool called the “SQL Server upgrade advisor”. The upgrade advisor analyzes installed components from earlier versions of SQL Server, and then generates a report that identifies issues to fix either before or after you upgrade. The analysis examines objects that can be accessed, such as scripts, stored procedures, triggers, and trace files. Upgrade Advisor cannot analyze desktop applications or encrypted stored procedures. Refer the links towards the end of the post to know how to get the Upgrade Advisor. The SQL Server Profiler Another great tool that you can use is the one most SQL Server developers & administrators use often – the SQL Server profiler. SQL Server Profiler provides functionality to monitor the “Deprecation” event, which contains: Deprecation announcement – equivalent to features to be deprecated in a future release of SQL Server Deprecation final support – equivalent to features to be deprecated in the next release of SQL Server You can learn more using the links towards the end of the post. A basic checklist There are a lot of finer points that need to be taken care of when upgrading your database. But, it would be worth-while to identify a few basic steps in order to make your database compliant with the next version of SQL Server: Monitor the current application workload (on a test bed) via the Profiler in order to identify usage of features marked as Deprecated If none appear, you are all set! (This almost never happens) Note down all the offending queries and feature usages Run analysis sessions using the SQL Server upgrade advisor on your database Based on the inputs from the analysis report and Profiler trace sessions, Incorporate solutions for the breaking changes first Next, incorporate solutions for the discontinued features Revisit and document the upgrade strategy for your deployment scenarios Revisit the fall-back, i.e. rollback strategies in case the upgrades fail Because some programming changes are dependent upon the SQL server version, this may need to be done in consultation with the development teams Before any other enhancements are incorporated by the development team, send out the database changes into QA QA strategy should involve a comparison between an environment running the old version of SQL Server against the new one Because minimal application changes have gone in (essential changes for SQL Server version compliance only), this would be possible As an ongoing activity, keep incorporating changes recommended as per the deprecated features list As a DBA, update your coding standards to ensure that the developers are using ANSI compliant code – this code will require a change only if the ANSI standard changes Remember this: Change management is a continuous process. Keep revisiting the product release notes and incorporate recommended changes to stay prepared for the next release of SQL Server. May the power of SQL Server be with you!

• SQL SERVER – A Puzzle Part 3 – Fun with SEQUENCE in SQL Server 2012 – Guess the Next Value

  - by pinaldave

  Before continuing this blog post – please read the two part of the SEQUENCE Puzzle here A Puzzle – Fun with SEQUENCE in SQL Server 2012 – Guess the Next Value and A Puzzle Part 2 – Fun with SEQUENCE in SQL Server 2012 – Guess the Next Value Where we played a simple guessing game about predicting next value. The answers the of puzzle is shared on the blog posts as a comment. Now here is the next puzzle based on yesterday’s puzzle. I recently shared the puzzle of the blog post on local user group and it was appreciated by attendees. First execute the script which I have written here. Today’s script is bit different than yesterday’s script as well it will require you to do some service related activities. I suggest you try this on your personal computer’s test environment when no one is working on it. Do not attempt this on production server as it will for sure get you in trouble. The purpose to learn how sequence behave during the unexpected shutdowns and services restarts. Now guess what will be the next value as requested in the query. USE AdventureWorks2012 GO -- Create sequence CREATE SEQUENCE dbo.SequenceID AS BIGINT START WITH 1 INCREMENT BY 1 MINVALUE 1 MAXVALUE 500 CYCLE CACHE 100; GO -- Following will return 1 SELECT next value FOR dbo.SequenceID; ------------------------------------- -- simulate server crash by restarting service -- do not attempt this on production or any server in use ------------------------------------ -- Following will return ??? SELECT next value FOR dbo.SequenceID; -- Clean up DROP SEQUENCE dbo.SequenceID; GO Once the server is restarted what will be the next value for SequenceID. We can learn interesting trivia’s about this new feature of SQL Server using this puzzle. Hint: Pay special attention to the difference between new number and earlier number. Can you see the same number in the definition of the CREATE SEQUENCE? Bonus Question: How to avoid the behavior demonstrated in above mentioned query. Does it have any effect of performance? I suggest you try to attempt to answer this question without running this code in SQL Server 2012. You can restart SQL Server using command prompt as well. I will follow up of the answer in comments below. Recently my friend Vinod Kumar wrote excellent blog post on SQL Server 2012: Using SEQUENCE, you can head over there for learning sequence in details.

• Connect Team Foundation Service/TFS 2012 with Visual Studio 2010 &amp; Visual Studio 2008

  - by Vishal

  Hello, Microsoft finally released the Team Foundation Service in late October 2012 after its long time in the preview phase. I was already using the TFS Preview which was free but I was happy to see Microsoft releasing the Team Foundation Service also FREE for upto 5 users. Isn't that great news? I know there are bunch of other free source control repositories (Github, Bitbucket, SVN etc.) out there but I somehow like TFS better. Also the other good thing about the final release was that I didn’t had to do any kind of migration of my code from preview to final release version. Just changed the TFS connection URL and it worked like a charm. Anyways, if you are a startup with small team and need some awesome Source Control along with all the good Project Management, Continuous Integration (Build, Test, Deploy), Team Collaboration, Agile/Scrum planning etc. features than Team Foundation Service is your answer. Microsoft has not yet released their pricing for more than 5 users and will be releasing it sometime in early 2013. What if as of now you have a team more than 5 users and you want to use Team Foundation Service, the good news is you can use it for FREE but when they release the final pricing, you will have to transition to the paid plan. Lot of story, getting to the point, connecting to Team Foundation Service with Visual Studio 2012 is straight forward and would work out of the box but it wont for previous versions of Visual Studio. You will have to upgrade to the latest service pack first and than install the forward compatibility pack. (1st : Service Packs & 2nd: Forward Compatibility packs) For Visual Studio 2010: Visual Studio 2010 Service Pack 1. Visual Studio 2010 forward compatibility for TFS 2012 and Team Foundation Service.         For Visual Studio 2008: Visual Studio 2008 Service Pack 1. Visual Studio 2008 forward compatibility for TFS 2012 & Team Foundation Service. Restart your system. Visual Studio 2008 will not work if you only put https://xxx.visualstudio.com. You will have to put your collection name too as shown below.       By the way, it doesn’t matter if you are an Apple Application Developer or Android App Developer, you can still use Team Foundation Service as your source control. Below are few links to connect to Team Foundation Service with other IDEs: Connect Eclipse to Team Foundation Service. Connect XCode to Team Foundation Service. Happy coding. Vishal Mody

• Today VS 2010 SP1 comes out, any news on the roadmap for Visual Studio 2012?

  - by Abel

  Today Visual Studio 2010 SP1 comes out as general availability release. This made me wondering about the upcoming release of Visual Studio 2012: What are Microsoft's plans for Visual Studio 2012? I heard they'll come with a new version every two years. Are there any open fora or discussions? When will a preview be publicly available? But most importantly: what are the new highlights, improvements in .NET and C#/F#/VB (and C++ of course, request from Stijn)?

• Application Integration Future &ndash; BizTalk Server &amp; Windows Azure (TechEd 2012)

  - by SURESH GIRIRAJAN

  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… BizTalk Server feature enhancements Manageability: ESB Tool Kit is going to be part of the core BizTalk product and Setup. Visualize BizTalk artifact dependencies in BizTalk administration console. HIS administration using configuration files. Performance: Improvements in ordered send port scenarios Improved performance in dynamic send ports and ESB, also to configure BizTalk host handler for dynamic send ports. Right now it runs under default host, which does not enable to scale. MLLP adapter enhancements and DB2 client transaction load balancing / client bulk insert. Platform Support: Visual Studio 2012, Windows 8 Server, SQL Server 2012, Office 15 and System Center 2012. B2B enhancements to support latest industry standards natively. Connectivity Improvements: Consume REST service directly in BizTalk SharePoint integration made easier. Improvements to SMTP adapter, to add macros for sending same email with different content to different parties. Connectivity to Azure Service Bus relay, queues and topics. DB2 client connectivity to SQL Server and SQL Server connectivity to Informix. CICS Http client connectivity to Windows. Azure: Use Azure as IaaS/PaaS for BizTalk environment. 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 Hybrid Connectivity 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…
