  • Need some advice on Networking research paper topic...

    - by user498541
    Hello I need a research topic for my networking paper. This is my first networking course I am taking so I have not gone into the actual protocols such as TCP/ip, HTTP, etc.(I have just begun chapter 4 for of network+). What would you suggest for a relatively easy to understand topic to research for my paper(that is also easy write about)?... I am kinda interested in research video game multi-player networking but I don't know if that's out of my league. -Topic can be on anything related to networking(p2p, internet, server architecture etc) -Paper has to be entirely researched on the internet -2-3 pages in length

  • ADNOC talks about 50x increase in performance

    - by KLaker
    If you are still wondering about how Exadata can revolutionise your business then I would recommend watching this great video which was recorded at this year's OpenWorld. First a little background...The Abu Dhabi National Oil Company for Distribution (ADNOC) is an integrated energy company that was founded in 1973. ADNOC Distribution markets and distributes petroleum products and services within the United Arab Emirates and internationally. As one of the largest and most innovative government-owned petroleum companies in the Arab Gulf, ADNOC Distribution is renowned and respected for the exceptional quality and reliability of its products and services. Its five corporate divisions include more than 200 filling stations (a number that is growing at 8% annually), more than 150 convenience stores, 10 vehicle inspection stations, as well as wholesale and retail sales of bulk fuel, gas, oil, diesel, and lubricants. ADNOC selected Oracle Exadata Database Machine after extensive research because it provided them with a single platform that can run mixed workloads in a single unified machine: "We chose Oracle Exadata Database Machine because it.offered a fully integrated and highly engineered system that was ready to deploy. With our infrastructure running all the same technology, we can operate any type of Oracle Database without restrictions and be prepared for business growth," said Ali Abdul Aziz Al-Ali, IT division manager, ADNOC Distribution. ".....we could consolidate our transaction processing and business intelligence onto one platform. Competing solutions are just not capable of doing that." - Awad Ahmed Ali El-Sidiq, Senior Database Administrator, ADNOC Distribution In this new video Awad Ahmen Ali El Sidddig, Senior DBA at ADNOC, talks about the impact that Exadata has had on his team and the whole business. ADNOC is using our engineered systems to drive and manage all their workloads: from transaction systems to payments system to data warehouse to BI environment. A true Disk-to-Dashboard revolution using Engineered Systems. This engineered approach is delivering 50x improvement in performance with one queries running 100x faster! The IT has even revolutionised some of their data warehouse related processes with the help of Exadata and now jobs that were taking over 4 hours now run in a few minutes.  To watch the video click on the image below which will take you to our Oracle YouTube page: (if the above link does not work, click here: http://www.youtube.com/watch?v=zcRpxc6u5Ic) Now that queries are running 100x faster and jobs are completing in minutes not hours, what is next for the IT team at ADNOC? Like many of our customers ADNOC is now looking to take advantage of big data to help them better align their business operations with customer behaviour and customer insights. To help deliver this next level of insight the IT team is looking at the new features in Oracle Database 12c such as the new in-memory feature to deliver even more performance gains.  The great news is that Awad Ahmen Ali El Sidddig was awarded DBA of the Year - EMEA within our Data Warehouse Global Leaders programme and you can see the badge for this award pop-up at the start of video. Well done to everyone at ADNOC and thanks for spending the time with us at OOW to create this great video.

  • Hotmail — avoid sign up confirmation / lost password being marked as spam

    - by Xerxes Cameron
    When sending legit large volume Emails from our IP (e.g. for sign up confirmation or Lost password) it gets marked as Junk in Hotmail. In the past, there was the Sender ID SPF Record Submission Form, where you could put yourself on the radar of Microsoft. See this old discussion. However, as of April 2012 this has been abandoned. Any hints what to do now? What is a good way to contact the Hotmail team?

  • How can a code editor effectively hint at code nesting level - without using indentation?

    - by pgfearo
    I'm writing an XML text editor that provides 2 view options for the same XML text, one indented (virtually), the other left-justified. The motivation for the left-justified view is to help users 'see' the whitespace characters they're using for indentation of plain-text or XPath code without interference from indentation that is an automated side-effect of the XML context. I want to provide visual clues (in the non-editable part of the editor) for the left-justified mode that will help the user, but without getting too elaborate. I tried just using connecting lines, but that seemed too busy. The best I've come up with so far is shown in a mocked up screenshot of the editor below, but I'm seeking better/simpler alternatives (that don't require too much code). [Edit] Taking the heatmap idea (from: @jimp) I get something like this: or even these alternates:

  • My new DNS change works from America but not Sweden

    - by Dougie
    Several hours ago i changed nameserver and DNS info on one of my domains at my domainregistar. When i access the domain from my home computers and when my friends access the domain they get to the old ip-adress hosting the dead site(We all live in Sweden). But when i access the website from my mobile phone or through google.com/translate or North American proxies the website is shown like it should. Why is this?, does it take time for change to take effect for diffrent locations/countries? I find it very strange and would like to start using my site now. Do you think it will change or could i've been doing something wrong?

  • SQL SERVER – 4 Tips for ETL Software IDE Developers

    - by pinaldave
    In a previous blog, I introduced the notion of Semantic Types. To an end-user, a seamlessly integrated semantic typing engine significantly increases the ease of use of an ETL IDE (integrated development environment, or developer studio). This led me to think about other ease-of-use issues I have encountered while building ETL applications. When I get stumped while programming, I find myself asking the variations on these questions: “How do I…?” “Now what?” “Why isn’t this working?” “Why do I have to redo the work I just did?” It seems to me that a good ETL IDE will anticipate these questions and seek to answer them before they are even asked. So here are my tips to help software vendors build developer IDEs that actually make development easier. How do I…? While developing an ETL application, have you ever asked yourself: “How do I set up the connection to my SQL Server database?”,“How do I import my table definitions from Access?”, etc. An easy answer might be “read the manual” but sometimes product manuals are not robust or easily accessible. So, integrating robust how-to instructions directly into your ETLstudio would help users get the information they need at the time they need it. Now what? IDEs in general know where you last clicked or performed an action using an input device such as a keyboard; so they should be able to reasonably predict the design context you are in and suggest the next steps accordingly. Context-sensitive suggestions based on the state of the user’s work will help users move forward in ETL application development. Why isn’t this working? Or why do I have to wait till I compile to be told about a critical design issue? If an ETL IDE is smart enough to signal to users what in their design structures is left to be completed or has been completed incorrectly, then the developer can spend much less time in the designàcompileàerror-correct loop. Just-in-time validation helps users detect and correct programming errors earlier in the ETL development life cycle. Why do I have to redo the work I just did? In ETL development, schemas, transformation rules, connectivity objects, etc., can be reused in various situations. Using mouse-clicks to build and manage libraries of reusable design objects implies that the application development effort should decrease over time and as the library acquires more objects. I met a great company at SQL Pass that is trying to address many of these usability issues. Check them out at www.expressor-software.com. What other ease-of-use suggestions do you have for ETL software vendors? Please post your valuable comments. ?Reference: Pinal Dave (http://blog.SQLAuthority.com) Filed under: Best Practices, Pinal Dave, PostADay, SQL, SQL Authority, SQL Query, SQL Server, SQL Tips and Tricks, T SQL, Technology Tagged: ETL

  • What's In Storage?

    - by [email protected]
    Oracle Flies South for Storage Networking Event Storage Networking World (now simply called SNW) is the place you'll find the most-comprehensive education on storage, infrastructure, and the datacenter in the spring of 2010. It's also the place where you'll see Oracle. During the April 12-15 event in Orlando, Florida, the industry's premiere presentations on storage trends and best practices are combined with hands-on labs covering storage management and IP storage. You'll also have the opportunity to learn about Oracle's Sun storage solutions, from Flash and open storage to enterprise disk and tape. Plus, if you stop by booth 207 in the expo hall, you might walk away with a bookish prize: an Amazon Kindle, courtesy of Oracle. Proving, once again, that education can be quite rewarding.

  • Lessons from a SAN Failure

    - by Bill Graziano
    At 1:10AM Sunday morning the main SAN at one of my clients suffered a “partial” failure.  Partial means that the SAN was still online and functioning but the LUNs attached to our two main SQL Servers “failed”.  Failed means that SQL Server wouldn’t start and the MDF and LDF files mostly showed a zero file size.  But they were online and responding and most other LUNs were available.  I’m not sure how SANs know to fail at 1AM on a Saturday night but they seem to.  From a personal standpoint this worked out poorly: I was out with friends and after more than a few drinks.  From a work standpoint this was about the best time to fail you could imagine.  Everything was running well before Monday morning.  But it was a long, long Sunday.  I started tipsy, got tired and ended up hung over later in the day. Note to self: Try not to go out drinking right before the SAN fails. This caught us at an interesting time.  We’re in the process of migrating to an entirely new set of servers so some things were partially moved.  This made it difficult to follow our procedures as cleanly as we’d like.  The benefit was that we had much better documentation of everything on the server.  I would encourage everyone to really think through the process of implementing your DR plan and document as much as possible.  Following a checklist is much easier than trying to remember at night under pressure in a hurry after a few drinks. I had a series of estimates on how long things would take.  They were accurate for any single server failure.  They weren’t accurate for a SAN failure that took two servers down.  This wasn’t bad but we should have communicated better. Don’t forget how many things are outside the database.  Logins, linked servers, DTS packages (yikes!), jobs, service broker, DTC (especially DTC), database triggers and any objects in the master database are all things you need backed up.  We’d done a decent job on this and didn’t find significant problems here.  That said this still took a lot of time.  There were many annoyances as a result of this.  Small settings like a login’s default database had a big impact on whether an application could run.  This is probably the single biggest area of concern when looking to recreate a server.  I’d encourage everyone to go through every single node of SSMS and look for user created objects or settings outside the database. Script out your logins with the proper SID and already encrypted passwords and keep it updated.  This makes life so much easier.  I used an approach based on KB246133 that worked well.  I’ll get my scripts posted over the next few days. The disaster can cause your DR process to fail in unexpected ways.  We have a job that scripts out all logins and role memberships and writes it to a file.  This runs on the DR server and pulls from the production server.  Upon opening the file I found that the contents were a “server not found” error.  Fortunately we had other copies and didn’t need to try and restore the master database.  This now runs on the production server and pushes the script to the DR site.  Soon we’ll get it pushed to our version control software. One of the biggest challenges is keeping your DR resources up to date.  Any server change (new linked server, new SQL Server Agent job, etc.) means that your DR plan (and scripts) is out of date.  It helps to automate the generation of these resources if possible. Take time now to test your database restore process.  We test ours quarterly.  If you have a large database I’d also encourage you to invest in a compressed backup solution.  Restoring backups was the single larger consumer of time during our recovery. And yes, there’s a database mirroring solution planned in our new architecture. I didn’t have much involvement in things outside SQL Server but this caused many, many things to change in our environment.  Many applications today aren’t just executables or web sites.  They are a combination of those plus network infrastructure, reports, network ports, IP addresses, DTS and SSIS packages, batch systems and many other things.  These all needed a little bit of attention to make sure they were functioning properly. Profiler turned out to be a handy tool.  I started a trace for failed logins and kept that running.  That let me fix a number of problems before people were able to report them.  I also ran traces to capture exceptions.  This helped identify problems with linked servers. Overall the thing that gave me the most problem was linked servers.  In order for a linked server to function properly you need to be pointed to the right server, have the proper login information, have the network routes available and have MSDTC configured properly.  We have a lot of linked servers and this created many failure points.  Some of the older linked servers used IP addresses and not DNS names.  This meant we had to go in and touch all those linked servers when the servers moved.

  • How do you successfully hire out a few programmers to make it cost effective?

    - by Chris
    Many of us know this situation well: we're a one-man (woman) development team, we need some extra help to keep up with all the tasks, the budget is small and we decide to get some help. But hiring someone is difficult. Either the person is inexperienced and I end up becoming their full-time teacher in the hopes they will produce work they way I want, or the person is skilled but for whatever reason doesn't hand over code within budget that I can just plug in and use without reworking it myself. Any thoughts/ideas?

  • The right way to start out in game development/design [closed]

    - by Marco Sacristão
    Greetings everyone I'm a 19 year old student looking for some help in the field of game development. This question may or may not seem a bit overused, but the fact is that game development has been my life long dream, and after several hours of search I've realized that I've been going in circles for the past three or four months whilst doing such research on how to really get down and dirty with game development, therefor I decided to ask you guys if you could help me out at all. Let me start off with some information about me and things i've already learned about GameDev which might help you out on helping me out (wordplay!): I'm not an expert programmer, but I do have knowledge on how to program in several languages including C and Java (Currently learning Java in my degree in Computer Engineering), but my methodology might not be most correct in terms of syntax (hence my difficulty in starting out, i'm afraid that the starting point might not be the most correct, and it would deploy a wrongful development methodology that would be to corrected later on, in terms of game development or other projects). I have yet to work in a project as large as a game, never in my learning curve of programming I've done a project to the scale of a video game, only very small software (PHP Front-ends and Back-ends, with some basic JQuery and CSS knowledge). I'm not the biggest mathematician or physicist, but I already know that is not a problem, because there are several game engines already available for use and integration with home-made projects (Box2D, etc). I've also learned about some libraries that could be included in said projects, to ease out some process in game development, like SDL for example. I do not know how sprites, states, particles or any specific game-related techniques work. With that being said, you can see that I have some ideas on game development, but I have absolutely no clue on how to design and produce a game, or even how game-like mechanics work. It does not have to be a complex game just to start out, I'd rather learn the basic of game design (Like 2D drawing, tiling, object collision) and test that out in a language that I feel comfortable in which could be later on migrated to other platforms, as long that what I've learned is the correct way to do things, and not just something that I've learned from some guy on Youtube by replicating that code on the video. I'm sorry if my question is not in the best format possible, but I've got so many questions on my mind that are still un-answered that I don't know were to start! Thank you for reading.

    I have an issue with my monitor. I just installed Ubuntu 11.10, but the monitor that is plugged in doesn't appear anywhere. And by doesn't appear, I mean that in the "Displays" menu, it doesn't even appear as "Unknown", I just have my screen that appears and nothing else. It is connected through VGA, and the monitor is recognized with no problem on Windows 7. It is a Dell monitor. I'm not a pro with Ubuntu, so any help to diagnose the issue would be really helpful (and help me learn how to fix this kind of monitor issue in the future) Thanks !

  • Preview of MSDN Library Changes

    - by ScottGu
    The MSDN team has been working some potential changes to the online MSDN Library designed to help streamline the navigation experience and make it easier to find the .NET Framework information you need. To solicit feedback on the proposed changes while they are still in development, they’ve posted a preview version of some proposed changes to a new MSDN Library Preview site which you can check out.  They’ve also created a survey that leads you through the ideas and asks for your opinions on some of the changes.  We’d very much like to have as many people as possible people take the survey and give us feedback. Quick Preview of Some of the Changes Below are some examples of a few of the changes being proposed: Streamlined .NET Namespaces Navigation The current MSDN Class Library lists all .NET namespaces in a flat-namespace (sorted alphabetically): Two downsides of the above approach are: Some of the least-used namespaces are listed first (like Microsoft.Aspnet.Snapin and Microsoft.Build.BuildEngine) All sub-namespaces are listed, which makes the list a little overwhelming, and page-load times to be slow The new MSDN Library Preview Site now lists “System” namespaces first (since those are the most used), and the home-page lists just top-level namespace groups – which makes it easier to find things, and enables the page to load faster:   Class overview and members pages merged into a single topic about each class Previously you had to navigate to several different pages to find member information about types: Links to these are still available in the MSDN Library Preview Site TOC – but the members are also now listed on the overview page, which makes it easy to quickly find everything in one place: Commonly used things are nearer the top of the page One of the other usability improvements with the new MSDN Library Preview Site is that common elements like “Code Examples” and “Inheritance Hierarchy” (for classes) are now listed near the top of the help page – making them easy to quickly find: Give Us Feedback with a Survey Above are just a few of the changes made with the new MSDN preview site – there are many other changes also rolled into it.  The MSDN team is doing usability studies on the new layout and navigation right now, and would very much like feedback on it. If you have 15 minutes and want to help vote on which of these ideas makes it into the production MSDN site, please visit this survey before June 30, play with the changes a bit, and let the MSDN team know what you think. Important Note: the MSDN preview site is not a fully functional version of MSDN – it’s really only there to preview the new ideas themselves, so please don’t expect it to be integrated with the rest of MSDN, with search, etc.  Once the MSDN team gets feedback on some of the changes being proposed they will roll them into the live site for everyone to use. Hope this helps, Scott

  • OpenGL ES 2.0: Using VBOs?

    - by Bunkai.Satori
    OpenGL VBOs (vertex buffer objects) have been developed to improve performance of OpenGL (OpenGL ES 2.0 in my case). The logic is that with the help of VBOs, the data does not need to be copied from client memory to graphics card on per frame basis. However, as I see it, the game scene changes continuously: position of objects change, their scaling and rotating change, they get animated, they explode, they get spawn or disappear. In such highly dynamic environment, such as computer game scene is, what is the point of using VBOs, if the VBOs would need to be constructed on per-frame basis anyway? Can you please help me to understand how to practically take beneif of VBOs in computer games? Can there be more vertex based VBOs (say one per one object) or there must be always exactly only one VBO present for each draw cycle?

  • Sed problem in a Bash script

    - by moata_u
    Hello there. I'm having a problem using the sed command . I'm trying to write a bash script that does the following : search for the line that contain :@ then save the line that contained :@ and replace it with new line as in the following: #! /bin/bash echo "Please enter the ip address of you file"<br> read ipnumber<br> find=`grep ':@' application.properties` # find the line<br> input="connection.url=jdbc\racle\:thin\:@$ipnumber\:1521\:billz" # preparing new line<br> echo `sed "s/'${find}'/'${input}'/g" application.properties` # replace old with new line <br> The problem is: nothing happens. I've already tried to use "${find}" instead of '${find}'

  • Record and Play your WebLogic Console Tasks Like a DVR

    - by james.bayer
    Automation using WebLogic Scripting Tool Today on the Oracle internal mailing list for WebLogic Server questions someone asked how to automate the configuration of the thread model for WebLogic Server and they were having trouble with the jython scripting syntax.  I’ve previously written about this feature called Work Managers and the associated constraints.  However, I did not show how to automate the process of configuring this without the console using WebLogic Scripting Tool – the jython scripting automation environment abbreviated as WLST.  I’ve written some very basic introductions to WLST before and there is also an Oracle By Example on the subject, but this is a bit more advanced.  Fear not because there is a really easy-to-use feature of the WLS console that lets you “Record” user actions just like a DVR.  Using these recordings of the web-based console, you can easily create a script even if you are unfamiliar with the WLST syntax and API.  I’m a big fan of both DVR’s and automation as can be evidenced with this old Halloween picture taken during simpler times.  Obviously the Cast Away and The Big Labowski references show some age.  I was a big Tivo fan-boy back in the day and I still think it’s the best DVR. I strongly believe that WebLogic Scripting Tool (WLST) is an absolutely essential tool for automating administration tasks in anything beyond a development environment.  Even in development environments you can make a case that it makes sense to start the automation for environments downstream.  I promise you that once you start using it for any tasks that you do even semi-regularly, you won’t go back to clicking through the console.  It’s simply so much more efficient and less error-prone to run a script. Let’s say you need to create a Work Manager and MaxThreadsConstraint – the easy way to do it is configure it in the WLS console first while capturing the commands with a recording.  See the images for the simple steps – click to enlarge. Record Console Configurations to a File Review the Recordings and Make Slight Modifications In order to make the recorded .py file directly callable as a stand-alone script I added calls to the connect() and edit() functions at the beginning and calls to disconnect() and exit() at the end – otherwise the main section of the script was provided by the console recording.  Below is the resulting file I saved as d:/temp/wm.py connect('weblogic','welcome1', 't3://localhost:7001') edit() startEdit()   cd('/SelfTuning/wl_server') cmo.createMaxThreadsConstraint('MaxThreadsConstraint-0')   cd('/SelfTuning/wl_server/MaxThreadsConstraints/MaxThreadsConstraint-0') set('Targets',jarray.array([ObjectName('com.bea:Name=examplesServer,Type=Server')], ObjectName)) cmo.setCount(5) cmo.unSet('ConnectionPoolName')   cd('/SelfTuning/wl_server') cmo.createWorkManager('WorkManager-0') cd('/SelfTuning/wl_server/WorkManagers/WorkManager-0') set('Targets',jarray.array([ObjectName('com.bea:Name=examplesServer,Type=Server')], ObjectName))   cmo.setMaxThreadsConstraint(getMBean('/SelfTuning/wl_server/MaxThreadsConstraints/MaxThreadsConstraint-0')) cmo.setIgnoreStuckThreads(false)   activate() disconnect() exit() Run the Script If you want to test it be sure to delete the Work Manager and MaxThreadConstraint that you had previously created in the console.  Do something like the following - set up the environment and tell WLST to execute the script which happens in the first 2 lines, the rest doesn’t require any user input: D:\Oracle\wls11g\wlserver_10.3\samples\domains\wl_server\bin>setDomainEnv.cmd D:\Oracle\wls11g\wlserver_10.3\samples\domains\wl_server>java weblogic.WLST d:\temp\wm.py   Initializing WebLogic Scripting Tool (WLST) ...   Welcome to WebLogic Server Administration Scripting Shell   Type help() for help on available commands   Connecting to t3://localhost:7001 with userid weblogic ... Successfully connected to Admin Server 'examplesServer' that belongs to domain 'wl_server'.   Warning: An insecure protocol was used to connect to the server. To ensure on-the-wire security, the SSL port or Admin port should be used instead.   Location changed to edit tree. This is a writable tree with DomainMBean as the root. To make changes you will need to start an edit session via startEdit().   For more help, use help(edit)   Starting an edit session ... Started edit session, please be sure to save and activate your changes once you are done. Activating all your changes, this may take a while ... The edit lock associated with this edit session is released once the activation is completed. Activation completed Disconnected from weblogic server: examplesServer     Exiting WebLogic Scripting Tool.   Now if you go back and look in the console the changes have been made and we now have a compete script.  Of course there is a full MBean reference and you can learn the nuances of jython and WLST, but why not the WLS console do most of the work for you!  Happy scripting.

  • Ubuntu 11.10 cannot boot, gets stuck at BusyBox

    - by Ivan Dokov
    I am using Ubuntu 11.10. An hour ago I had my laptop Sony Vaio VPCEB1S1E running. I saw there are updates to install and I installed them. I turned off the laptop and now when I turn it on it loads until BusyBox v1.18.4 appears. I've seen suggestions for solving this on askubuntu. I booted Puppy Linux from USB and repaired the partition where the Ubuntu is installed. I rebooted but it did not help. I saw other suggestions like writing "exit" at the BusyBox prompt. This didn't help either. I love the Ubuntu OS, but these days I get problems like this while booting. The last times I could repair it with GParted, but then it wasn't a problem with BusyBox, it was some other error, like "cannot boot /". The same problem had occurred on Ubuntu 10.10 and there I had repaired it with GParted.

  • Booting Ubuntu EFI on Macbook Pro Apple Bootmanager

    - by user279771
    Following: http://www.rodsbooks.com/ubuntu-efi/ and https://help.ubuntu.com/community/UEFIBooting#Detect_.28U.29EFI_firmware_processor_architecture I have ubuntu booting on my macbook pro with both refined and the native apple loader working, however, I would like to get the "Improving the Boot Method" (i believe it is called the kernel efi stub loader) working with the Apple Boot manager (the article only explains for refined), but have found no articles explaining this. Can anyone help with this? Below is what I have: What I have is the following: /dev/sda apple partitions /boot ext3 (root) ext3 swap side notes: From what I understand, I should have had my boot partition as fat32/hfs+... I can always switch it or copy the kernel to the apple EFI partition. (I tried creating /boot as an hfs+ partition during installation but was unable. Even after installing hfsprogs, although I was able to create an hfs+ partition in gparted I couldn't use the partition as /boot in ubiquity).

  • Scrum for Team Foundation Server 2010

    - by Martin Hinshelwood
    I will be presenting a session on “Scrum for TFS2010” not once, but twice! If you are going to be at the Aberdeen Partner Group meeting on 27th April, or DDD Scotland on 8th May then you may be able to catch my session. Credit: I want to give special thanks to Aaron Bjork from Microsoft who provided me with most of my material He is a Scrum and Power Point genius. Scrum for Team Foundation Server 2010 Synopsis Visual Studio ALM (formerly Visual Studio Team System (VSTS)) and Team Foundation Server (TFS) are the cornerstones of development on the Microsoft .NET platform. These are the best tools for a team to have successful projects and for the developers to have a focused and smooth software development process. For TFS 2010 Microsoft is heavily investing in Scrum and has already started moving some teams across to using it. Martin will not be going in depth with Scrum but you can find out more about Scrum by reading the Scrum Guide and you can even asses your Scrum knowledge by having a go at the Scrum Open Assessment. Come and see Martin Hinshelwood, Visual Studio ALM MVP and Solution Architect from SSW show you: How to successfully gather requirements with User stories How to plan a project using TFS 2010 and Scrum How to work with a product backlog in TFS 2010 The right way to plan a sprint with TFS 2010 Tracking your progress The right way to use work items What you can use from the built in reporting as well as the Project portals available on from the SharePoint dashboard The important reports to give your Product Owner / Project Manager Walk away knowing how to see the project health and progress. Visual Studio ALM is designed to help address many of these traditional problems faced by teams. It does so by providing a set of integrated tools to help teams improve their software development activities and to help managers better support the software development processes. During this session we will cover the lifecycle of creating work items and how this fits into Scrum using Visual Studio ALM and Team Foundation Server. If you want to know more about how to do Scrum with TFS then there is a new course that has been created in collaboration with Microsoft and Scrum.org that is going to be the official course for working with TFS 2010. SSW has Professional Scrum Developer Trainers who specialise in training your developers in implementing Scrum with Microsoft's Visual Studio ALM tools. Ken Schwaber and and Sam Guckenheimer: Professional Scrum Development Technorati Tags: Scrum,VS ALM,VS 2010,TFS 2010
