• Can't build and run an android test project created using "ant create test-project" when tested proj

  - by Mike

  I have a module that builds an app called MyApp. I have another that builds some testcases for that app, called MyAppTests. They both build their own APKs, and they both work fine from within my IDE. I'd like to build them using ant so that I can take advantage of continuous integration. Building the app module works fine. I'm having difficulty getting the Test module to compile and run. Using Christopher's tip from a previous question, I used android create test-project -p MyAppTests -m ../MyApp -n MyAppTests to create the necessary build files to build and run my test project. This seems to work great (once I remove an unnecessary test case that it constructed for me and revert my AndroidManifest.xml to the one I was using before it got replaced by android create), but I have two problems. The first problem: The project doesn't compile because it's missing libraries. $ ant run-tests Buildfile: build.xml [setup] Project Target: Google APIs [setup] Vendor: Google Inc.

• SQLAuthority News – SafePeak’s SQL Server Performance Contest – Winners

  - by pinaldave

  SafePeak, the unique automated SQL performance acceleration and performance tuning software vendor, announced the winners of their SQL Performance Contest 2011. The contest quite unique: the writer of the best / most interesting and most community liked “performance story” would win an expensive gadget. The judges were the community DBAs that could participating and Like’ing stories and could also win expensive prizes. Robert Pearl SQL MVP, was the contest supervisor. I liked most of the stories and decided then to contact SafePeak and suggested to participate in the give-away and they have gladly accepted the same. The winner of best story is: Jason Brimhall (USA) with a story about a proc with a fair amount of business logic. Congratulations Jason! The 3 participants won the second prize of $100 gift card on amazon.com are: Michael Corey (USA), Hakim Ali (USA) and Alex Bernal (USA). And 5 participants won a printed copy of a book of mine (Book Reviews of SQL Wait Stats Joes 2 Pros: SQL Performance Tuning Techniques Using Wait Statistics, Types & Queues) are: Patrick Kansa (USA), Wagner Bianchi (USA), Riyas.V.K (India), Farzana Patwa (USA) and Wagner Crivelini (Brazil). The winners are welcome to send safepeak their mail address to receive the prizes (to “info ‘at’ safepeak.com”). Also SafePeak team asked me to welcome you all to continue sending stories, simply because they (and we all) like to read interesting stuff) as well as to send them ideas for future contests. You can do it from here: www.safepeak.com/SQL-Performance-Contest-2011/Submit-Story Congratulations to everybody! I found this very funny video about SafePeak: It looks like someone (maybe the vendor) played with video’s once and created this non-commercial like video: SafePeak dynamic caching is an immediate plug-n-play performance acceleration and scalability solution for cloud, hosted and business SQL server applications. By caching in memory result sets of queries and stored procedures, while keeping all those cache correct and up to date using unique patent pending technology, SafePeak can fix SQL performance problems and bottlenecks of most applications – most importantly: without actual code changes. By the way, I checked their website prior this contest announcement and noticed that they are running these days a special end year promotion giving between 30% to 45% discounts. Since the installation is quick and full testing can be done within couple of days – those have the need (performance problems) and have budget leftovers: I suggest you hurry. A free fully functional trial is here: www.safepeak.com/download, while those that want to start with a quote should ping here www.safepeak.com/quote. Good luck!

• Messing with the Team

  - by Robert May

  Good Product Owners will help the team be the best that they can be.  Bad product owners will mess with the team and won’t care about the team.  If you’re a product owner, seek to do good and avoid bad behavior at all costs.  Remember, this is for YOUR benefit and you have much power given to you.  Use that power wisely. Scope Creep The product owner has several tools at his disposal to inject scope into an iteration.  First, the product owner can use defects to inject scope.  To do this, they’ll tell the team what functionality that they want to see in a feature.  Then, after the feature is developed, the Product Owner will decide that they don’t really like how the functionality behaves.  To change it, rather than creating a new story, they’ll add a defect.  The functionality is correct, as designed, but the Product Owner doesn’t like it.  By creating the defect, the Product Owner destroys the trust that the team has of the product owner.  They may not be able to count the story, because the Product Owner changed the story in the iteration, and the team then ends up looking like they have low velocity for something over which they have no control.  This is bad.  One way to deal with this is to add “Product Owner Time” to the iteration.  This will slow the velocity, but then the ScrumMaster can tell stake holders that this time is strictly in place to deal with bad behavior of the Product Owner. Another mechanism often used to inject Scope is the concept of directed development.  Outside of planning, stand-ups, or any other meeting, the Product Owner will take a developer aside and ask them to complete a task for them.  This is bad!  The team should be allocating all of their time to development.  If the Product Owner asks for a favor, then time that would normally be used for development will be used for a pet project of the Product Owner and the team will not get credit for this work.  Selfish product owners do this, and I typically see people who were “managers” do this behavior.  Authoritarian command and control development environments also see this happen.  The best thing that can happen is for the team member to report the issue to the ScrumMaster and the ScrumMaster to get very aggressive with management and the Product Owner to try and stop the behavior.  This may result in the ScrumMaster being fired, but if the behavior continues, Scrum is doomed.  This problem is especially bad in cases where the team member’s direct supervisor is the Product Owner.  I don’t recommend that the Product Owner or ScrumMaster have a direct report relationship with team members, since team members need the ability to say no.  To work around this issue, team members need to say no.  If that fails, team members need to add extra time to the iteration to deal with the scope creep injection and accept the lower velocity. As discussed above, another mechanism for injecting scope is by changing acceptance tests after the work is complete.  This is similar to adding defects to change scope and is bad.  To get around, add time for Product Owner uncertainty to the iteration and make sure that stakeholders are aware of the need to add this time because of the Product Owner. Refusing to Prioritize Refusing to prioritize causes chaos for the team.  From the team’s perspective, things that are not important will be worked on while things that the team knows are vital will be ignored.  A poor Product Owner will often pick the stories for the iteration on a whim.  This leads to the team working on many different aspects of the product and results in a lower velocity, since each iteration the team must switch context to the new area of development. The team will also experience confusion about priorities.  In one iteration, Feature X was the highest priority and had to be done.  Then, the following iteration, even though parts of Feature X still need to be completed, no stories to address them will be in the iteration.  However, three iterations later, Feature X will again become high priority. This will cause the team to not trust the Product Owner, and eventually, they’ll stop caring about the features they implement.  They won’t know what is important, so to insulate themselves from the ever changing chaos, they’ll become apathetic to all features.  Team members are some of the most creative people in a company.  By losing their engagement, the company is going to have a substandard product because the passion for the product won’t be in the team. Other signs that the Product Owner refuses to prioritize is that no one outside of the product owner will be consulted on priorities.  Additionally, the product, release, and iteration backlogs will be weak or non-existent. Dealing with this issue is not easy.  This really isn’t something the team can fix, short of taking over the role of Product Owner themselves.  An appeal to the stake holders might work, but only if the Product Owner isn’t a “manager” themselves.  The ScrumMaster needs to protect the team and do what they can to either get the Product Owner to prioritize or have the Product Owner replaced. Managing the Team A Product Owner that is also the “boss” of team members is a Scrum team that is waiting to fail.  If your boss tells you to do something, failing to do that something can cause you to be fired.  The team needs the ability to tell the Product Owner NO.  If the product owner introduces scope creep, the team has a responsibility to tell the Product Owner no.  If the Product Owner tries to get the team to commit to more than they can accomplish in an iteration, the team needs the ability to tell the Product Owner no. If the Product Owner is your boss and determines your pay increases, you’re probably not going to ever tell them no, and Scrum will likely fail.  The team can’t do much in this situation. Another aspect of “managing the team” that often happens is the Product Owner tries to tell the team how to develop the stories that are in the iteration.  This is one reason why I recommend that Product Owners are NOT technical people.  That way, the team can come up with the tasks that are needed to accomplish the stories and the Product Owner won’t know better.  If the Product Owner is technical, the ScrumMaster will need to take great care to protect the team from the ScrumMaster changing how the team thinks they need to implement the stories. Product Owners can also try to manage the team by their body language.  If the team says a task is going to take 6 hours to complete, and the Product Owner disagrees, they will use some kind of sour body language to indicate this disagreement.  In weak teams, this may cause the team to revise their estimate down, which will result in them taking longer than estimated and may result in them missing the iteration.  The ScrumMaster will need to make sure that the Product Owner doesn’t send such messages and that the team ignores them and estimates what they REALLY think it will take to complete the tasks.  Forcing the team to deal with such items in the retrospective can be helpful. Absenteeism The team is completely dependent upon the Product Owner to develop features for the customer.  The Product Owner IS the voice of the customer and without them, the team will lack direction.  Being the Product Owner is a full time job!  If the Product Owner cannot dedicate daily time with the team, a different product owner should be found. The Product Owner needs to attend every stand-up, planning meeting, showcase, and retrospective that the team has.  The team also must be able to have instant communication with the product owner.  They must not be required to schedule meetings to speak with their product owner.  The team must be the highest priority task that the Product Owner has. The best way to work around an absent Product Owner is to appoint a new Product Owner in the team.  This person will be responsible for making the decisions that the Product Owner should be making and to act as the liaison to the absent Product Owner.  If the delegate Product Owner doesn’t have authority to make decisions for the team, Scrum will fail.  If the Product Owner is absent, the ScrumMaster should seek to have that Product Owner replaced by someone who has the time and ability to be a real Product Owner. Making it Personal Too often Product Owners will become convinced that their ideas are the ones that matter and that anyone who disagrees is making a personal attack on them.  Remember that Product Owners will inherently be at odds with many people, simply because they have the need to prioritize.  Others will frequently question prioritization because they only see part of the picture that Product Owners face. Product Owners must have a thick skin and think egos.  If they don’t, they tend to make things personal, which causes them to become emotional and causes them to take actions that can destroy the trust that team members have in the Product Owner. If a Product Owner is making things person, the best thing that team members can do is reassure them that its not personal, but be firm about doing what is best for the Company and for the users.  The ScrumMaster should also spend significant time coaching the Product Owner on how to not react emotionally and how to accept criticism without becoming defensive. Conclusion I’m sure there are other ways that a Product Owner can mess with the team, but these are the most common that I’ve seen.  I would encourage all Product Owners to seek to be a good Product Owner.  If you find yourself behaving in any of the bad product owner ways, change your behavior today!  Your team will thank you. Remember, being Product Owner is very difficult!  Product Owner is one of the most difficult roles in Scrum.  However, it can also be one of the most rewarding roles in Scrum, since Product Owners literally see their ideas brought to life on the computer screen.  Product Owners need to be very patient, even in the face of criticism and need to be willing to make tough decisions on priority, but then not become offended when others disagree with those decisions.  Companies should spend the time needed to find the right product owners for their teams.  Doing so will only help the company to write better software.

• tfs 2010 RC Agile Process template update New Task progress report

  Maybe my next post will just be about why I am so excited and impressed with the out of the box templates.  But, for this first blog with my new focus, I thought I would just walk through the process I went through to create a task progress report (to enhance the out of the box Agile template). So, I started with the MSF for Agile Development 5.0 RC template.  After reviewing the template, I came away pretty excited about many of the new reports.  I am especially excited about the reporting services reports.  The big advantage I see here is that these are querying the Warehouse directly instead of the Analysis Services Cube which means that they are much closer to real-time which I find very important for reports like Burndown and task status.  One report that I focused on right away was the User Story Progress Report.  An overview is shown below: This report is very useful, but a lot of our internal managers really prefer to manage at the task level and either dont have stories in TFS or would like to view this type of report for tasks in addition to the User Stories.  So, what did I do? Step 1: Download the Agile Template In VS 2010 RC, open Process Template Manager from Team->Team Project Collection Settings.  Download the MSF for Agile Development template to your local file system.  A project template is a folder of xml files.  There is a ProcessTemplate.xml in the root and then a bunch of directories for things like Work Item Definitions and Queries, Reports, Shared Documents and Source Control Settings.  Step 2: Copy the folder My plan here is to make a new template with all of my modifications.  You can also just enhance update the MSF template.  However, I think it is cleaner when you start making modifications to make your own template.  So, copy the folder and name it with your new template name. Step 3: Change Template Name Open ProcessTemplate.xml and change the <name> of the template. Step 4: Copy the rdl of the Report you want to use a starting point In my case, I copied Stories Progress.rdl and named the file Task Progress Breakdown.rdl.  I reviewed the requirements for the new report with some of the users here and came up with this plan.  Should show tasks and be expandable to show subtasks.  Should add Assigned To and Estimated Finish Date as 2 extra columns. Step 5: Walkthrough the existing report to understand how it works The main thing that I do here is try to get the sql to run in SQL Management Studio.  So, I can walkthrough the process of building up the data for the report. After analyzing this particular report I found a couple of very useful things.  One, this report is already built to display subtasks if I just flip the IncludeTasks flag to 1.  So, if you are using Stories and have tasks assigned to each story.  This might give you everything you want.  For my purposes, I did make that change to the Stories Progress report as I find it to be a more useful report to be able to see the tasks that comprise each story.  But, I still wanted a task only version with the additional fields. Step 6: Update the report definition I tend to work on rdl in visual studio directly as xml.  Especially when I am just altering an existing report, I find it easier than trying to deal with the BI Studio designer.  For my report I made the following changes. Updated Fields Removed Stack Rank and Replaced with Priority since we dont use Stack Rank Added FinishDate and AssignedTo Changed the root deliverable SQL to pull @tasks instead of @deliverablecategory and added a join CurrentWorkItemView for FinishDate and Assigned to SELECT cwi.[System_Id] AS ID FROM [CurrentWorkItemView] cwi             WHERE cwi.[System_WorkItemType] IN (@Task)             AND cwi.[ProjectNodeGUID] = @ProjectGuid SELECT lh.SourceWorkItemID AS ID FROM FactWorkItemLinkHistory lh             INNER JOIN [CurrentWorkItemView] cwi ON lh.TargetWorkItemID = cwi.[System_Id]             WHERE lh.WorkItemLinkTypeSK = @ParentWorkItemLinkTypeSK                 AND lh.RemovedDate = CONVERT(DATETIME, '9999', 126)                 AND lh.TeamProjectCollectionSK = @TeamProjectCollectionSK                 AND cwi.[System_WorkItemType] NOT IN (@DeliverableCategory) Added AssignedTo and FinishDate columns to the @Rollups table Added two columns to the table used for column headers <Tablix Name="ProgressTable">         <TablixBody>           <TablixColumns>             <TablixColumn>               <Width>2.7625in</Width>             </TablixColumn>             <TablixColumn>               <Width>0.5125in</Width>             </TablixColumn>             <TablixColumn>               <Width>3.4625in</Width>             </TablixColumn>             <TablixColumn>               <Width>0.7625in</Width>             </TablixColumn>             <TablixColumn>               <Width>1.25in</Width>             </TablixColumn>             <TablixColumn>               <Width>1.25in</Width>             </TablixColumn>           </TablixColumns> Added Cells for the two new headers Added Cells to the data table to include the two new values (Assigned to & Finish Date) Changed a bunch of widths that would change the format of the report to display landscape and have room for the two additional columns Set the Value of the IncludeTasks Parameter to 1 <ReportParameter Name="IncludeTasks">       <DataType>Integer</DataType>       <DefaultValue>         <Values>           <Value>=1</Value>         </Values>       </DefaultValue>       <Prompt>IncludeTasks</Prompt>       <Hidden>true</Hidden>     </ReportParameter> Change a few descriptions on how the report should be used This is the resulting report I have attached the final rdl. Step 7: Update ReportTasks.xml Last step before the template is ready for use is to update the reportTasks.xml file in the reports folder.  This file defines the reports that are available in the template.           <report name="Task Progress Breakdown" filename="Reports\Task Progress Breakdown.rdl" folder="Project Management" cacheExpiration="30">             <parameters>               <parameter name="ExplicitProject" value="" />             </parameters>             <datasources>               <reference name="/Tfs2010ReportDS" dsname="TfsReportDS" />             </datasources>           </report> Step 8: Upload the template Open the process Template Manager just like Step 1.  And upload the new template. Thats it.  One other note, if you want to add this report to existing team project you will have to go into reportmanager (the reporting services portal) and upload the rdl to that projects directory.Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Advice on SCRUM for the solitary developer [closed]

  - by ProfK

  Possible Duplicate: Agile for the Solo Developer I am looking for advice on the SCRUM process for a solitary developer. Most SCRUM resources I see focus on its use in a team environment, hence my question here. I'd like some guidance on structuring and managing my projects for SCRUM, with me as a solitary developer and business owner, but still occasionally including my clients for input and feedback. Areas I'm not clear on include resolving my backlog into 'sprintable' project areas and stories, defining user stories properly with a view to being digested by developer level users, defining feasible sprints for a single developer etc. Essentially I'm looking for advice on moving from using scrum in a team/office environment, with colleagues and project manager, and using chaos/cowboy-coding on my own, to assuming the role of PM myself and adopting scrum for work on my own. Any advice is welcome.

• When to mark a user story as done in scrum?

  - by Saeed Neamati

  There is a notion in scrum that emphasizes delivery of workable units at the end of each sprint. Each workable unit also maps directly of indirectly to a user story and when in new sprint PO introduces new PBI (new user stories), this means that practically team can't always go back to previous user stories to do the rest of the job, which in turn means that when you implement a user story, you should do it as complete as it's known to the team in that time, and you shouldn't forget anything (something like "I'm sorry, I've forgotten to implement validation for that input control" or "I didn't know that cross-browser check is part of the user story"). At the other hand, test, backward compatibility, acceptance criteria, deployment and more and more concepts come after each user story. So, when can team members know that the user story is done completely, not just for demo, and start a new one?

• Walmart and Fusion Apps

  - by ultan o'broin

  Photograph: Misha Vaughan I attended Fusion Apps (yes, I know I am supposed to say "Oracle Fusion Applications", but stuffy old style guides are a turn-off in interwebs conversations) User Experience Advocate (FXA) training in Long Beach, California last week; a suitable location as ODTUG KSCOPE 11 was kicking off and key players were in the area. As a member of Oracle's Apps-UX team I know the Fusion Apps messaging, natch, and done some other Fusion Apps go-to-market content work too. For the messaging details themselves, see Lonneke Dikmans (@lonnekedikmans) great blog, by the way. However, I wanted some 'formal' training combined with the opportunity to meet and learn from people already out there delivering those messages. The idea in me reaching out to Misha Vaughan, Apps-UX FXA maven, to get me onto this training was that in addition to my UX knowledge, I could leverage my location in EMEA and hit up customer events more quickly and easily. Those local user groups do like to hear the voice of locals too you know (so I need to work on that mid-Atlantic accent). I'm looking forward to such opportunities. The training was all smashing stuff, just the right level of detail, delivered professionally and with great style and humor. I was especially honored to be paired off for my er, coaching with Debra Lilley (@debralilley), who shared with everyone all kinds of tips and insights from her experiences of delivering the message and demo. For me, that was the real power of the FXA event--the communal, conversational aspect--the meeting up with people who had done all this for real, the sharing in their experiences, while learning along with other newbies. Sorry, but that all-important social aspect doesn't work so well with remote meetings. Katie Candland (Apps-UX) gave us a great tour of the Fusion Apps demo and included some useful presentational tips too (any excuse to buy that iPad). It's clear to me that the Fusion Apps messaging and demos really come alive with real-world examples that local application users will recognize, and I picked up some "yes, that's my job made easier" scene-stealers from Debra and Karen Brownfield too, to add to the great ones already provided. This power of examples shouldn't surprise anyone, they've long been a mainstay of applications user assistance, popular with users. We'll offer customers different types of example topics in the Fusion Apps online help too (stay tuned), and we know from research how important those 3S's (stories, scenarios, and simulations) are to users when they consume and apply information. Well, we've got the simulation, now it's time for more stories and scenarios. If you get a chance to participate in an FXA event (whether you are an Oracle employee or otherwise), I'd encourage it. It's committing your time and energy for sure, but I got real bang for the buck from it for my everyday job too. Listening to the room's feedback on the application demo really brought our internal design work to life, and I picked up on some things that I need to follow up on (like how you alphabetically sort stuff in other languages). User experience is after all, about users. What will I be doing next, and what would I like to see happen? Obviously, I need to develop my story-telling links with the people I met in Long Beach and do some practicing with the materials, and then get out there and deliver them at a suitable location. The demo is what it is right now, and that's a super-rich demo that I know everyone will want to see and ask questions about. Then, as mentioned by attendees at the FXA event, follow up on those translated and localized messages for EMEA (and APAC), that deal with different statutory or reporting requirements of the target markets. Given my background I would say that, wouldn't I? However, language is part of the UX, and international revenue is greater than US-only revenue for Oracle, so yes dear, we all need to get over the fact that enterprise apps users don't all speak, or want to speak, American-English. Most importantly perhaps, the continued development of a strong messaging community between Oracle and partners and customers where we can swap and share those FXA messaging stories and scenarios about Fusion Apps in a conversational way. The more the better, a combination of online and face-to-face meetings. I must also mention the great dinner after the event at Parker's Lighthouse, and the fun myself and Andrew Gilmour (Apps-UX) had at our end of the table talking about just about everything except Fusion Apps with Ronald Van Luttikhuizen and Ben Prusinski (who now understands the difference between Cork and Dublin people. I hope). Thanks to all the Apps-UXers who helped bring the FXA training to town, and to Debra and all the others that I am too jetlagged to mention right who were instrumental in making it happen for me. Here's to the next one. And the Walmart angle? That was me doing my Robert Scoble (ScO'bilizer?)-style guerilla smart phone research in Walmart in Long Beach, before the FXA event. It's all about stories for me. You can read more about it on the appslab blog (see the comments).

• New Java EE/GlassFish Testimonial

  - by reza_rahman

  As you may be aware, we have been making a concerted effort to ask successful Java EE/GlassFish adopters to come forward with their stories. A number of such stories were shared at this year's GlassFish Community event at JavaOne. In addition to Adam Bien's testimonial (which we posted earlier), another story that really stands out is the one from Stephan Janssen. Stephan is one of the main organizers of Devoxx and the webmaster of the popular Parleys e-learning platform. Parleys, which won the Duke's Choice award this year, runs on GlassFish as does the Devoxx CFP/registration website. Stephan's story is particularly interesting because he talks about his reasons and experience of moving from Tomcat to GlassFish and from Spring to Java EE. See what Stephan had to say here.

• Real life example of an agile game development process

  - by Ken

  I'm trying to learn about applying agile methodologies to game development. But seems to be impossible to find real life examples. What I am looking for are things like; Initial user stories Final user stories (complete, covering the entire game requirements) Acceptance criteria Task list Sprint backlogs (before and after each sprint) The agile books seem to have some limited examples, many of which seem contrived. In this era of open source software, there must be an documented example of the process applied to a game that is publicly available. I am asking specifically about games because they are so different from normal applications. Regular applications are built to all users to complete specific tasks in order to get stuff done(book a room, print a report etc). People play games for much less tangible reasons, so I think the process is significantly different. [it doesn't have to be scrum, it could be any process, just needs to be a real life example game and be reasonably complete]

• A Comparison of Store Layouts

  - by David Dorf

  Belus Capital Advisors is an independent stock market research firm that sometimes rolls up its sleeves and walks retail stores.  This month Brian Sozzi walked both Macy's and Sears and snapped pictures along the way.  The results are a good lesson in what to do and what not to do in retail.  The dichotomy between the two brands is stark, and Brian's pictures tell the stories of artistry and neglect.  For example, look at these two pictures: Where do you want to shop for sneakers?  The left picture shows the Finish Line store within Macy's and the right shows empty shelves at Sears.  The pictures really show the importance of assortments, in-stock inventory, and presentation.  Take a look at the two stories, and pay particular attention to the pictures of Sears. 19 Photos that Show the New Magic of Macy’s Sears is Vanishing from our Minds, the Shocking 18 Photos That Show Why

• How to estimate tasks in scrum?

  - by Arian

  Let's say we have a backlog of User Stories, each with an estimated number of Story Points, and now we're doing the Sprint Planning. Now, the Stories should be broken down into tasks and many Scrum resources suggest that each task should be estimated in person-hours. Since all questions have been discussed by the team at this point, estimating a task should not take longer than a minute. However, since a task should not be longer than a day, assuming a three week sprint with 8 developers means 120 tasks, and taking two hours only for estimations seems to be a bit much to me. I know that experienced teams can skip or short-cut task estimations, but let's say we're not at that stage yet. In your experience, how many tasks are there in a sprint* and how long should it take to estimate all of them? (Estimating only half of them doesn't make much sense, does it?) (*) I know that depends on sprint length and team size, so let's assume 8 developers and three weeks.

• Should your client be able to view your project management board?

  - by bizso09

  We're making a bespoke software for our client and use Codebase for our project management. Is it a good idea to let our client view our project management board? The advantages that we thought of are that this would enhance the cooperation between the client and the dev team, following agile practices. He would essentially become part of our team. It would also reduce communication overhead and make sure we're on the same page. The client could track the progression of the system and make suggestions along the way on the user stories. In addition, he could submit bugs or feature requests. The disadvantages that we though of are that some aspects of the board might be too technical to the client. He would suggest changes to the user stories too often and he might view some content that we normally wouldn't want our client to see. For example, when we compromise on technology or functionality, the client might question that and insist on doing things one way or the other.

• Using Definition of Done to Drive Agile Maturity

  - by Dylan Smith

  I’ve been an Agile Coach at a lot of different clients over the years, and I want to share an approach I use to help them adopt and mature over time. It’s important to realize that “Agile” is not a black/white yes/no thing. Teams can be varying degrees of agile. I think of this as their agile maturity level. When I coach teams I want them to start out being a little agile, and get more agile as they mature. The approach I teach them is to use the definition of done as a technique to continuously improve their agile maturity over time. We’re probably all familiar with the concept of “Done Done” that represents what *actually* being done a feature means. Not just when a developer says he’s done right after he writes that last line of code that makes the feature kind-of work. Done Done means the coding is done, it’s been tested, installers and deployment packages have been created, user manuals have been updated, architecture docs have been updated, etc. To enable teams to internalize the concept of “Done Done”, they usually get together and come up with their Definition of Done (DoD) that defines all the activities that need to be completed before a feature is considered Done Done. The Done Done technique typically is applied only to features (aka User Stories). What I do is extend this to apply to several concepts such as User Stories, Sprints, Releases (and sometimes Check-Ins). During project kick-off I’ll usually sit down with the team and go through an exercise of creating DoD’s for each of these concepts (Stories/Sprints/Releases). We’ll usually start by just brainstorming a bunch of activities that could end up in these various DoD’s. Here’s some examples: Code Reviews StyleCop FxCop User Manuals Updated Architecture Docs Updated Tested by QA Tested by UAT Installers Created Support Knowledge Base Updated Deployment Instructions (for Ops) written Automated Unit Tests Run Automated Integration Tests Run Then we start by arranging these activities into the place they occur today (e.g. Do you do UAT testing only once per release? every sprint? every feature?). If the team was previously Waterfall most of these activities probably end up in the Release DoD. An extremely mature agile team would probably have most of these activities in the DoD for the User Stories (because an extremely mature agile team will probably do continuous deployment and release every story). So what we need to do as a team, is work to move these activities from their current home (Release DoD) down into the Sprint DoD and eventually into the User Story DoD (and maybe into the lower-level Check-In DoD if we decide to use that). We don’t have to move them all down to User Story immediately, but as a team we figure out what we think we’re capable of moving down to the Sprint cycle, and Story cycle immediately, and that becomes our starting DoD’s. Over time the team makes an effort to continue moving activities down from Release->Sprint->Story as they become more agile and more mature. I try to encourage them to envision a world in which they deploy to production as each User Story is completed. They would need to be updating User Manuals, creating installers, doing UAT testing (typical Release cycle activities) on every single User Story. They may never actually reach that point, but they should envision that, and strive to keep driving the activities down closer to the User Story cycle s they mature. This is a great technique to give a team an easy-to-follow roadmap to mature their agile practices over time. Sure there’s other aspects to maturity outside of this, but it’s a great technique, that’s easy to visualize, to drive agility into the team. Just keep moving those activities (aka “gates”) down the board from Release->Sprint->Story. I’ll try to give an example of what a recent client of mine had for their DoD’s (this is from memory, so probably not 100% accurate): Release Create/Update deployment Instructions For Ops Instructional Videos Updated Run manual regression test suite UAT Testing In this case that meant deploying to an environment shared across the enterprise that mirrored production and asking other business groups to test their own apps to ensure we didn’t break anything outside our system Sprint Deploy to UAT Environment But not necessarily actually request UAT testing occur User Guides updated Sprint Features Video Created In this case we decided to create a video each sprint showing off the progress (video version of Sprint Demo) User Story Manual Test scripts developed and run Tested by BA Deployed in shared QA environment Using automated deployment process Peer Code Review Code Check-In Compiled (warning-free) Passes StyleCop Passes FxCop Create installer packages Run Automated Tests Run Automated Integration Tests PS – One of my clients had a great question when we went through this activity. They said that if a Sprint is by definition done when the end-date rolls around (time-boxed), isn’t a DoD on a sprint meaningless – it’s done on the end-date regardless of whether those other activities are complete or not? My answer is that while that statement is true – the sprint is done regardless when the end date rolls around – if the DoD activities haven’t been completed I would consider the Sprint a failure (similar to not completing what was committed/planned – failure may be too strong a word but you get the idea). In the Retrospective that will become an agenda item to discuss and understand why we weren’t able to complete the activities we agreed would need to be completed each Sprint.

• How do you get a high paying job programming in finance?

  - by q303

  Hi, I'm interested in eventually programming for a financial company. Unfortunately, I have a degree in linguistics with a minor in CS along with 4 years experience in .NET. I picked .NET because I thought that it would be more used in the financial world. I've heard some horror stories about badly done VBA Excel programming and being way underpaid...but then I've heard great stories about highly skilled C++ programming along with high pay (including some feedback to previous questions). I just get the impression that unless you have a MS in CS from a top 10/20 school, it might not be realistic. For those of you doing programming for bankers/traders, how did you break in?

• How to make sprint planning fun

  - by Jacob Spire

  Not only are our sprint planning meetings not fun, they're downright dreadful. The meetings are tedious, and boring, and take forever (a day, but it feels like a lot longer). The developers complain about it, and dread upcoming plannings. Our routine is pretty standard (user story inserted into sprint backlog by priority story is taken apart to tasks tasks are estimated in hours repeat), and I can't figure out what we're doing wrong. How can we make the meetings more enjoyable? ... Some more details, in response to requests for more information: Why are the backlog items not inserted and prioritized before sprint kickoff? User stories are indeed prioritized; we have no idea how long they'll take until we break them down into tasks! From the (excellent) answers here, I see that maybe we shouldn't estimate tasks at all, only the user stories. The reason we estimate tasks (and not stories) is because we've been getting story-estimates terribly wrong -- but I guess that's the subject for an altogether different question. Why are developers complaining? Meetings are long. Meetings are monotonous. Story after story, task after task, struggling (yes, struggling) to estimate how long it will take and what it involves. Estimating tasks makes user-story-estimation seem pointless. The longer the meeting, the less focus in the room. The less focused colleagues are, the longer the meeting takes. A recursive hate-spiral develops. We've considered splitting the meeting into two days in order to keep people focused, but the developers wouldn't hear of it. One day of planning is bad enough; now we'll have two?! Part of our problem is that we go into very small detail (in order to get more accurate estimations). But when we estimate roughly, we go way off the mark! To sum up the question: What are we doing wrong? What additional ways are there to make the meeting generally more enjoyable?

  A key question to answer for Java EE and GlassFish centers on proof of successful adoption. To that end, we have made a serious effort to ask Java EE/GlassFish adopters to tell us their stories. There were a number of such stories shared at this year's GlassFish Community event at JavaOne. One that particularly stands out is a testimonial by celebrated Java EE advocate and independent consultant Adam Bien. For those of you that don't know it, Adam was given the "Top Java Ambassador" award by this year's JAX Innvovation Awards. See what Adam had to say here. We'll share more of these testimonials in days to come, so stay tuned.

  I need to provide a quote to an external client for some software. I'm looking to use agile just for initial requirements building (which I'm experienced in from a developer perspective) but I need to do everything this is just a one man job. The client are having a hard time working out what there requirements are and the value I can add will be to sit down with them and work out what they want using user stories etc, I basically need to be a BA for a little bit. I am looking for good overview of the procedures to go through in the agile process for building requirements, and the continuing process a bit for further down the line. For example the initial inception through to elaboration of epics and building user stories (or not) just need to read a bit about it before the meeting so I know the best way to proceed if I spend a day with them. Having additional resources to provide to the client so that we are all on the same page would be useful too.

• Need help with memory leaks in RSS Reader

  - by Stilton

  I'm trying to write a simple RSS reader for the iPhone, and it appeared to be working fine, until I started working with Instruments, and discovered my App is leaking massive amounts of memory. I'm using the NSXMLParser class to parse an RSS feed. My memory leaks appear to be originating from the overridden delegate methods: - (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string and - (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName I'm also suspicious of the code that populates the cells from my parsed data, I've included the code from those methods and a few other key ones, any insights would be greatly appreciated. - (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string { if ([self.currentElement isEqualToString:@"title"]) { [self.currentTitle appendString:string]; } else if ([self.currentElement isEqualToString:@"link"]) { [self.currentURL appendString:string]; } else if ([self.currentElement isEqualToString:@"description"]) { [self.currentSummary appendString:string]; } } - (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName { if ([elementName isEqualToString:@"item"]) { //asdf NSMutableDictionary *item = [[NSMutableDictionary alloc] init]; [item setObject:currentTitle forKey:@"title"]; [item setObject:currentURL forKey:@"URL"]; [item setObject:currentSummary forKey:@"summary"]; [self.currentTitle release]; [self.currentURL release]; [self.currentSummary release]; [self.stories addObject:item]; [item release]; } } // Customize the appearance of table view cells. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } // Configure the cell. // Set up the cell int index = [indexPath indexAtPosition: [indexPath length] - 1]; CGRect contentRect = CGRectMake(8.0, 4.0, 260, 20); UILabel *textLabel = [[UILabel alloc] initWithFrame:contentRect]; if (self.currentLevel == 0) { textLabel.text = [self.categories objectAtIndex: index]; } else { textLabel.text = [[self.stories objectAtIndex: index] objectForKey:@"title"]; } textLabel.textColor = [UIColor blackColor]; textLabel.font = [UIFont boldSystemFontOfSize:14]; [[cell contentView] addSubview: textLabel]; //[cell setText:[[stories objectAtIndex: storyIndex] objectForKey: @"title"]]; [textLabel autorelease]; return cell; } - (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict { if ([elementName isEqualToString:@"item"]) { self.currentTitle = [[NSMutableString alloc] init]; self.currentURL = [[NSMutableString alloc] init]; self.currentSummary = [[NSMutableString alloc] init]; } if (currentElement != nil) { [self.currentElement release]; } self.currentElement = [elementName copy]; } - (void)dealloc { [currentElement release]; [currentTitle release]; [currentURL release]; [currentSummary release]; [currentDate release]; [stories release]; [rssParser release]; [storyTable release]; [super dealloc]; } // Override to support row selection in the table view. - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { // Navigation logic may go here -- for example, create and push another view controller. // AnotherViewController *anotherViewController = [[AnotherViewController alloc] initWithNibName:@"AnotherView" bundle:nil]; int index = [indexPath indexAtPosition: [indexPath length] - 1]; if (currentLevel == 1) { StoryViewController *storyViewController = [[StoryViewController alloc] initWithURL:[[stories objectAtIndex: index] objectForKey:@"URL"] nibName:@"StoryViewController" bundle:nil]; [self.navigationController pushViewController:storyViewController animated:YES]; [storyViewController release]; } else { RootViewController *rvController = [[RootViewController alloc] initWithNibName:@"RootViewController" bundle:nil]; rvController.currentLevel = currentLevel + 1; rvController.rssIndex = index; [self.navigationController pushViewController:rvController animated:YES]; [rvController release]; } }

• xmlns="> was not expected

  - by Anthony Shaw

  OK. I'm trying to work on communicating with the Pivotal Tracker API, which only returns data in an XML format. I have the following XML that I'm trying to deserialize into my domain model. <?xml version="1.0" encoding="UTF-8"? <stories type="array" count="2" total="2" <story <id type="integer"2909137</id <project_id type="integer"68153</project_id <story_typebug</story_type <urlhttp://www.pivotaltracker.com/story/show/2909137</url <current_stateunscheduled</current_state <description</description <nameTest #2</name <requested_byAnthony Shaw</requested_by <created_at type="datetime"2010/03/23 20:05:58 EDT</created_at <updated_at type="datetime"2010/03/23 20:05:58 EDT</updated_at </story <story <id type="integer"2909135</id <project_id type="integer"68153</project_id <story_typefeature</story_type <urlhttp://www.pivotaltracker.com/story/show/2909135</url <estimate type="integer"-1</estimate <current_stateunscheduled</current_state <description</description <nameTest #1</name <requested_byAnthony Shaw</requested_by <created_at type="datetime"2010/03/23 20:05:53 EDT</created_at <updated_at type="datetime"2010/03/23 20:05:53 EDT</updated_at </story </stories My 'story' object is created as follows: public class story { public int id { get; set; } public int estimate { get; set; } public int project_id { get; set; } public string story_type { get; set; } public string url { get; set; } public string current_state { get; set; } public string description { get; set; } public string name { get; set; } public string requested_by { get; set; } public string labels { get; set; } public string lighthouse_id { get; set; } public string lighthouse_url { get; set; } public string owned_by { get; set; } public string accepted_at { get; set; } public string created_at { get; set; } public attachment[] attachments { get; set; } public note[] notes { get; set; } } When I execute my deserialization code, I receive the following exception: Exception: There is an error in XML document (2, 2). Inner Exception: <stories xmlns='' was not expected. I can deserialize the individual stories just fine, I just cannot deserialize this xml into an array of 'story' objects And my serialization code var byteArray = Encoding.ASCII.GetBytes(value); var stream = new MemoryStream(byteArray); var deserializedObject = new XmlSerializer(typeof (story[])).Deserialize(stream) Does anybody have any ideas?

• Best Non-Microsoft/.NET Development Blogs and Podcasts

  - by Mark Lubin

  I really don't want to rile anyone's feathers and I really enjoy blogs like Joel, Coding Horror, Scott Hanselman, etc. However, what are some good blogs/podcasts that focus on other platforms besides Microsoft based ones or maybe even no particular platform at? In particular I am interested in areas like Python, Ruby, Java, C, but any area besides Microsoft fits the bill. There may be other similar questions to this but I think this one is unique since we might get some answers we wouldn't see otherwise, that is, everyone knows Coding Horror is great. Please try to refrain from religious debates; the content of the blog is more important than the platform they are talking about, I just want to get an idea of what is out there and worth the time.
