  Can someone make a junit test of this? public class PersonName { int NumberNames(String wholename) { // store the name passed in to the method String testname=wholename; // initialize number of names found int numnames=0; // on each iteration remove one name while(testname.length()>numnames) { // take the "white space" from the beginning and end testname = testname.trim(); // determine the position of the first blank // .. end of the first word int posBlank= testname.indexOf(' '); // cut off word /** * it continues to the stop sign because that is where you commanded it to end */ testname=testname.substring(posBlank+1,testname.length()); // System.out.println(numnames); // System.out.println(testname); numnames++; System.out.println(testname); } return numnames; } public static void main(String args[]) { PersonName One= new PersonName(); System.out.println(One.NumberNames("Bobby")); System.out.println(One.NumberNames("Bobby Smith")); System.out.println(One.NumberNames("Bobby L.

• Recovering a lost website with no backup?

  - by Jeff Atwood

  Unfortunately, our hosting provider experienced 100% data loss, so I've lost all content for two hosted blog websites: http://blog.stackoverflow.com http://www.codinghorror.com (Yes, yes, I absolutely should have done complete offsite backups. Unfortunately, all my backups were on the server itself. So save the lecture; you're 100% absolutely right, but that doesn't help me at the moment. Let's stay focused on the question here!) I am beginning the slow, painful process of recovering the website from web crawler caches. There are a few automated tools for recovering a website from internet web spider (Yahoo, Bing, Google, etc.) caches, like Warrick, but I had some bad results using this: My IP address was quickly banned from Google for using it I get lots of 500 and 503 errors and "waiting 5 minutes…" Ultimately, I can recover the text content faster by hand I've had much better luck by using a list of all blog posts, clicking through to the Google cache and saving each individual file as HTML. While there are a lot of blog posts, there aren't that many, and I figure I deserve some self-flagellation for not having a better backup strategy. Anyway, the important thing is that I've had good luck getting the blog post text this way, and I am definitely able to get the text of the web pages out of the Internet caches. Based on what I've done so far, I am confident I can recover all the lost blog post text and comments. However, the images that go with each blog post are proving…more difficult. Any general tips for recovering website pages from Internet caches, and in particular, places to recover archived images from website pages? (And, again, please, no backup lectures. You're totally, completely, utterly right! But being right isn't solving my immediate problem… Unless you have a time machine…)

• Controlling what data populates STAR

  - by user10747017

  Beginning with the Primavera Reporting Database 2.2\P6 Analytics 1.2 release, the first release that supported the P6 Extended Schema, a new ability was added to filter which projects could be included during an ETL run. In previous releases, all projects were included in an ETL run. Additionally, all projects with the option to enable publication are included in the ETL run by default.Because the reporting needs for P6 Extended Schema are different from those of STAR, you can define a filter that will limit the data that is included in the STAR schema. For example, your STAR schema can be filter to only include all projects in a specific Portfolio, or all projects with a project code assignment of 'For Analytics.'  Any criteria that can be defined in a Where clause and added to a view can be used to filter the projects included in the STAR schema. I highly suggest this approach when dealing with large databases. Unnecessary projects could cause the Extract portion of the ETL process to take longer. A table in STAR called etl_projectlist is the key for what projects are targeted during the ETL process. To setup the filter, perform the following steps:1. Connect to your Primavera P6 Project Management Database as Pxrptuser (extended schema owner) and create a new view:create or replace view star_project_viewasselect PROJECTOBJECTID objectidfrom projectportfolio pp, projectprojectportfolio pppwhere pp.objectid = ppp.PROJECTPORTFOLIOOBJECTIDand pp.name = 'STAR Projects'--The main field that MUST be selected in the view is the projectobjectid. Selecting any other field besides the projectobjectid will cause the view to be invalid and will not work. Any Where clause can be used, but projectobjectid is the key.2. In your STAR installation directory go the \res folder and edit the staretl.properties file.  Here you will define the view to be used.  Add the following line or update if exists:star.project.filter.ds1=star_project_view3. When running the  staretl.cmd or staretl.sh process the database link to Pxrtpuser will be accessed and this view will be used to populate the etl_projectlist table  with the appropriate projectobjectids as defined in the view created in step 1 above.

• Four Proven Advantages of Online Learning | Outside Cost, Accessibility or Flexibility

  - by Mohit Phogat

  Coursera believes that online courses complement and supplement traditional education (versus a common misconception online will “replace” traditional.) Our research shows that Coursera’s platform, when used concurrently with a traditional classroom setup, is ideal for “blended learning” (i.e., students watch lectures pre-class, then class-time focuses on interactive work and discussion.) Additionally, we agree with Brad Zomick of SkilledUp—an online learning aggregator—who acknowledges an online course “isn’t an alternative at all but rather a different path with its own rewards.” The advantages of Coursera and our apps for mobile were straightforward and conspicuous from the start: we’re free, open, and flexible to learners’ unique needs and style. Over the past two years, however, the evidence proves there are many more tangible benefits to open, online learning. In SkilledUp’s “The Advantages of Online Courses [Infographic]”–crafted from findings of leading educational research–four observations stand out from the overt characteristics: Speedier Learning - “Research shows that online students achieve same or better learning results in about half the time as those in traditional courses” More Active, Engaged & Motivated - Learners thrive “when working with coursework that is challenging but within their capacity to master.” Tangible Skill Building - with an “improved attitude toward learning” Better Teaching Quality - Courses are taught by experts, with various multimedia and cutting-edge technology, and “are usually better organized than traditional courses” This is only the beginning, Courserians! Everyday we hear your incredible stories on how open online courses enrich your lives and enhance your careers. Meanwhile we study the steady stream of scientific, big-data research proving their worth on a large-scale (such as UPenn’s latest research on the welcomed diversity in Coursera-hosted Wharton MBA courses.) Our motto “Learning without Limits” reminds us that open, online courses give tremendous opportunity to those that might not otherwise have access (or time, or money) to study at a high-caliber institution.

• login takes long time

  - by Arkaprovo Bhattacharjee

  I am using Ubuntu 12.04 from past 12 days. In the beginning login was fast enough after I put the password it hardly takes 3 to 4 sec to enter in desktop, but now its taking like more that 40 sec to show desktop after entering password. whats the problem, is there any solution? P.S there is only two programs (psensor and jupiter) that starts automatically after login. boot.log fsck from util-linux 2.20.1 /dev/sda6: clean, 254544/3325952 files, 2133831/13285632 blocks * Stopping Userspace bootsplash[164G[ OK ] * Stopping Flush boot log to disk[164G[ OK ] * Starting mDNS/DNS-SD daemon[164G[ OK ] Skipping profile in /etc/apparmor.d/disable: usr.sbin.rsyslogd Skipping profile in /etc/apparmor.d/disable: usr.bin.firefox * Starting bluetooth daemon[164G[ OK ] * Starting network connection manager[164G[ OK ] * Starting AppArmor profiles [170G [164G[ OK ] * Stopping System V initialisation compatibility[164G[ OK ] * Starting CUPS printing spooler/server[164G[ OK ] * Starting System V runlevel compatibility[164G[ OK ] * Starting Bumblebee supporting nVidia Optimus cards[164G[ OK ] * Starting LightDM Display Manager[164G[ OK ] * Starting save kernel messages[164G[ OK ] * Starting anac(h)ronistic cron[164G[ OK ] * Starting ACPI daemon[164G[ OK ] * Starting regular background program processing daemon[164G[ OK ] * Starting deferred execution scheduler[164G[ OK ] speech-dispatcher disabled; edit /etc/default/speech-dispatcher * Starting CPU interrupts balancing daemon[164G[ OK ]

• beginner - best way to do a 'Confirm' page? [closed]

  - by W_P

  I am a beginning web app developer, wondering about the best way to implement a "Confirm Page" upon form submission. I have heard that it's best for the script that a form POSTs to to be implemented by handling the POST data and then redirecting to another page, so the user isn't directly viewing the page that was POSTed to. My question is about the best way to implement a "Confirm before data save" page. Do I Have my form POST to a script, which marshals the data, puts in a GET, and redirects to the confirm page, which unmarshals and displays the data in another form, where the user can then either confirm (which causes another POST to a script that actually saves the data) or deny (which causes the user to be redirected back to the original form, with their input added)? Have my form POST directly to the confirm page, which is displayed to the user and then, like #1, gives the user the option to confirm or deny? Have my form GET the confirm page, which then does the expected behavior? I feel like there is a common-sense answer to this question that I am just not getting.

• How should developers handle subpar working conditions? [closed]

  - by ivar

  I have been working in my current job for less than a year and at the beginning didn't have the courage to say anything about the things that bothered me. Now I'm a bit fed up and need things to get better. The first problem is not random but I'll mention it anyway. We are running out of space so every new employee gets a smaller table. We are promised that the space problem will be fixed soon. Almost every employee has a different keyboard, mouse, headphones (if any). Mine are $10 keyboard, some random cheap mouse and some random crappy headphones with a mic. All these were used and dirty when I got them. The number of monitor is 1-3 and with different sizes. I have 2 nice monitors and can't complain but some are given 1 small monitor. When it's their first job they don't have the guts to ask for 2 even if most others have 2. Nobody seems to care too. Project manager asked if it's ok? He obviously said he can handle the 1 small one. Then the manager said you can go ask for 1 more. I'm watching this and think go and ask where? The company is trying to hire more people but is not doing much after the person has signed the contract. We are put in one room that is open to the hallway and it's super noisy. Almost like a zoo at times. Even if nobody is talking the crappy keyboards make too much noise. Is this normal? Am I too negative and should I just do my job with what I was given? Should I demand better things? Should the company have some system that everybody gets things in some price range?

• Hidden files in Nautilus after extracting ISO

  - by Luis Alvarado

  I need to first point to the image below to explain a bit about what I find weird here: I extracted the informacion from an ISO I from Nautilus I could only see two folders but from the terminal I can see the rest of the files and folders. This folders do not have the . character in from of them to hide them from plain sight. When I try to "Show hidden files" in Nautilus, Nautilus closes itself. It does not show the hidden folders or files. Somehow they are hidden without using the normal dot in the beginning of the name. The have my user permission but no way of seeing them from Nautilus. I can interact with them but the fact that they appear hidden when I can see them inside the ISO and after extracting them they disappear is what confuses me. What permission or setting makes this folders appear hidden and does not let Nautilus show them and like I said before, trying to show them with the "Show hidden files" option crashes Nautilus and exits it. Forcing me to have to open Nautilus again from the Launcher.

• Can thousands of backlinks from the same site harm PageRank?

  - by Dejan Pelzel

  I just noticed that one particular site has almost 7000 backlinks linking back to our website. The site is something like a news aggregator and for each post they created around 20 (sometimes much more) backlinks back to our page and they basically linked over 400 pages. I am beginning to get concerned that this amount of links might harm our page. They seem to have more backlinks to our page than all the other pages combined and more backlinks that our website has pages. We have seen a massive negative effect going on for quite a while and the PageRank seems to have dropped to None (Not even 0). But I am not sure when and why exactly that happened seeing that PageRank updates take quite a while to appear. The site linking to us is otherwise pretty reputable and doesn't seem to be having any problems with their rank. (PR 6 actually) I was thinking of using the Google disavow tool for this site, but I don't want to make things even worse. Do you think these are harmful? If so, how do I fix this? Thanks :)

• The Middle of Every Project

  - by andrew.sparks

  I read a quote somewhere “The middle of every successful project looks like a mess.” or something to that effect. I suppose the projects where the beginning, middle and end are a mess are the ones you need to watch out for. Right now we are in ramp up of the maintenance/support teams at a big project in the Nordics. We are facing a year of mixed mode operations, where we have production operations and the phased rollout to new locations in parallel. The support team supports, and the deployment team deploys. As usual the assumption right up to about a month or so before initial go-live was that the deployment team would carry the support. Not! Consequently we had a last minute scramble over the Christmas/New Year to fire up a support/maintenance team. While it is a bit messy and not perfect – the quality of the mess (I mean scramble) is not so bad. Weekly operational review with the operational delivery managers, written issue lists and assigned actions, candid discussions getting the problems on the table and documented, issues getting solved and moved off the table. So while the middle of a project might look like a mess (even the start) it is methodical use of project management tools of checklists and scheduled communication points that are helping us navigate out of the mess and bring it all under control.

• How can I make sense of the word "Functor" from a semantic standpoint?

  - by guillaume31

  When facing new programming jargon words, I first try to reason about them from an semantic and etymological standpoint when possible (that is, when they aren't obscure acronyms). For instance, you can get the beginning of a hint of what things like Polymorphism or even Monad are about with the help of a little Greek/Latin. At the very least, once you've learned the concept, the word itself appears to go along with it well. I guess that's part of why we name things names, to make mental representations and associations more fluent. I found Functor to be a tougher nut to crack. Not so much the C++ meaning -- an object that acts (-or) as a function (funct-), but the various functional meanings (in ML, Haskell) definitely left me puzzled. From the (mathematics) Functor Wikipedia article, it seems the word was borrowed from linguistics. I think I get what a "function word" or "functor" means in that context - a word that "makes function" as opposed to a word that "makes sense". But I can't really relate that to the notion of Functor in category theory, let alone functional programming. I imagined a Functor to be something that creates functions, or behaves like a function, or short for "functional constructor", but none of those seems to fit... How do experienced functional programmers reason about this ? Do they just need any label to put in front of a concept and be fine with it ? Generally speaking, isn't it partly why advanced functional programming is hard to grasp for mere mortals compared to, say, OO -- very abstract in that you can't relate it to anything familiar ? Note that I don't need a definition of Functor, only an explanation that would allow me to relate it to something more tangible, if there is any.

• How different is WPF from ASP.NET [closed]

  - by Tom

  I have been quickly moved over to a different project at work because the project needs more help. I was chosen because they are confident in my abilities and they thought I would be best fit for the next couple weeks to help finish the application out. I am a little nervous. I do tend to pick things up quickly. I was moved to a different project at the beginning of this year and now I know it like the back of my hand. Previously I was on another project. Both of these projects were an ASP.NET web application, which I believe is considered a winforms web application? The project I am moving to is a desktop WPF application. I have read that many people enjoy developing their applications with WPF. I just have never dealt/worked with WPF before. I like to consider myself pretty good at ASP.NET/C# and I do a solid job. We deal with a lot of data processing from the database and report generation. So I do get to experience C# more so than some web applications where the C# end of it is mostly just event driven and simple instructions. How different are the two? Will it be completely foreign to me? Or is it just a different way of looking at a problem and I can familiarize myself quickly? Thanks for the input.

• Should I start making connections even if I'm not ready for a job yet?

  - by James

  The first job is always the hardest to get and I'm not exception. I'm 23 years old and I have no college degree but planned on going to college this year if all goes well (CS of course). I'm self-studying java right now. I know most of the topics related to the language besides the more advanced topics and I'm beginning to look at open source projects. I would like to find a job (at least a part time job) after a year or two when I'll gain more experience and learn more about java technologies and other technologies that interest me. Finding a job will be a bit difficult because most of the people (or a lot of them at least) at my current age already have 2 years or more of experience, so I will be somewhat disadvantaged. Should I start building connections and joining websites such as linkedin ? I never bothered to look into it because I'm not much of a social network person. If I start contributing to open source projects and create personal projects for 2 years could I apply for jobs that require 1-2 years of experience? Does this experience count ?

• How do you stay productive when dealing with extremely badly written code?

  - by gaearon

  I don't have much experience in working in software industry, being self-taught and having participated in open source before deciding to take a job. Now that I work for money, I also have to deal with some unpleasant stuff, which is normal of course. Recently I was assigned to add logging to a large SharePoint project which is written by some programmer who obviously was learning to code on the job. After 2 years of collaboration, the client switched to our company, but the damage was done, and now somehow I need to maintain this code. Not that the code was too hard to read. Despite problems - each project has one class with several copy-pasted methods, enormous if nestings, Systems Hungarian, undisposed connections — it's still readable. However, I found myself absolutely unproductive despite working on something as simple as adding logging. Basically, I just need to go through the code step by step and add some trace calls. However, the idiocy of the code is so annoying that I get tired within 10 minutes of starting. In the beginning, I used to add using constructs, reduce nesting by reversing if's, rename the variables to readable names—but the project is large, and eventually I gave up. I know this is not the task I should be doing, but at least reducing the mess gave me some kind of psychological reward so I could keep going. Now the trick stopped working, and I still have 60% of my work to do. I started having headaches after work, and I no longer get the feeling of satisfaction I used to get - which would usually allow me to code for 10 hours straight and still feel fresh. This is not just one big rant, for I really do have an actual question: Is there a way to stay productive and not to fight the windmills? Is there some kind of psychological trick to stay focused on the task, instead of thinking “How stupid is that?” each time I see another clever trick by the previous programmer? The problem with adding logging is that I actually have to understand what the code does, and doing so hurts my brain in an unpleasant fashion.

• Breadcrumbs in a modern web application, make sense? [on hold]

  - by Xtreme Biker

  I'm currently beginning with the development of a new web application. The whole web application is going to be bookmarkable and all the pages accesible via GET requests and url parameters. Having said that, let's suppose I've got three entities in my application, Customer, Team and City. Each Customer and Team belong to a city and I've got a city-detail page which displays the detail for a concrete city. So next navigation cases are possible: Customers - Customer detail (id=2) - City detail (id=3) Football teams - Team detail (id=5) - City detail (id=3) Cities - City detail (id=3) There are three possible ways of ending up in a city detail view. My question is, does it make sense to implement a breadcrumb to show such a history, having it available in the browser itself? Would it be more appropiate to show a breadcrumb with the last case, no matter where we're coming from (hierarchical breadcrumb)? That's what Jakob Nielsen points out here: Offering users a Hansel-and-Gretel-style history trail is basically useless, because it simply duplicates functionality offered by the Back button, which is the Web’s second-most-used feature. A history trail can also be confusing: users often wander in circles or go to the wrong site sections. Having each point in a confused progression at the top of the current page doesn’t offer much help. Finally, a history trail is useless for users who arrive directly at a page deep within the site. Also, even if the history trail seems the most natural way to implement it, it requires an extra effort to keep the whole track being HTTP a stateless mean.

• Leveraging ERP Investments with EPM and BI Solutions

  - by john.orourke(at)oracle.com

  Now that many organizations have implemented ERP systems to automate and integrate their operational processes, IT investments are beginning to shift to the management systems i.e. EPM and BI tools and applications that integrate data from multiple transactional systems.  These solutions automate and integrate the management processes and enable organizations to achieve "management excellence" becoming smarter, more agile and more aligned than their competitors.  In fact the results of a recent IDC survey indicate that "Organizations that have implemented performance management more broadly are nearly four times more likely to be among the most competitive organizations in their industry."  One example of an organization that is leveraging their ERP investments with Oracle EPM and BI solutions is General Dynamics.  The Business Intelligence Collaborative (BIC) group within General Dynamics' IT organization assists various business units with the implementation, application support, and application hosting for their Business Intelligence and Enterprise Performance Management Applications.  Attend the Oracle Virtual Trade Show "Spotlight on Customer Success" on February 3rd to hear the details of how General Dynamics is using Oracle Essbase, Hyperion Planning, and Oracle BI to improve their planning, reporting and analysis processes and leverage their investments in Oracle E-Business Suite and other operational systems.   During the event, you can also hear about the latest developments and plans for Oracle Applications products, as well as what's coming with Oracle Fusion Applications. Here's a link to the Virtual Trade Show event overview and registration page.  The event runs from 8AM - 1PM PST/11AM - 4PM EST, and the EPM session is 10:30 - 11AM PST/1:30 - 2PM EST.    http://event.on24.com/event/26/79/15/rt/opFb.html?partnerref=internal I hope you'll join us on February 3rd!

• SQL SERVER – Get Schema Name from Object ID using OBJECT_SCHEMA_NAME

  - by pinaldave

  Sometime a simple solution have even simpler solutions but we often do not practice it as we do not see value in it or find it useful. Well, today’s blog post is also about something which I have seen not practiced much in codes. We are so much comfortable with alternative usage that we do not feel like switching how we query the data. I was going over forums and I noticed that at one place user has used following code to get Schema Name from ObjectID. USE AdventureWorks2012 GO SELECT s.name AS SchemaName, t.name AS TableName, s.schema_id, t.OBJECT_ID FROM sys.Tables t INNER JOIN sys.schemas s ON s.schema_id = t.schema_id WHERE t.name = OBJECT_NAME(46623209) GO Before I continue let me say I do not see anything wrong with this script. It is just fine and one of the way to get SchemaName from Object ID. However, I have been using function OBJECT_SCHEMA_NAME to get the schema name. If I have to write the same code from the beginning I would have written the same code as following. SELECT OBJECT_SCHEMA_NAME(46623209) AS SchemaName, t.name AS TableName, t.schema_id, t.OBJECT_ID FROM sys.tables t WHERE t.name = OBJECT_NAME(46623209) GO Now, both of the above code give you exact same result. If you remove the WHERE condition it will give you information of all the tables of the database. Now the question is which one is better – honestly – it is not about one is better than other. Use the one which you prefer to use. I prefer to use second one as it requires less typing. Let me ask you the same question to you – which method to get schema name do yo use? and Why?

• Defunct website taken over by spammer. How to stop them?

  - by Robert

  A friend of mine used to publish a small literary fiction magazine, both in print and on the web. In 2011 she announced that she was quitting, put a note on the website, and carefully unwound the subscriptions. She continued hosting the site (with all the back-issues available for free) until the beginning of this year, when she let the hosting lapse and the domain name expire. Today she discovered that some unknown person has purchased her former domain name and put up a modified version of her entire site. The design is different but all the content is the same, including all of the back-issues of the magazine (and the stories by diverse authors contained within), their cover art, news posts, and even her contact information. All the content would have been available from Archive.org, so it's no mystery how they got it. The only thing noticeably changed is a column added to the front page titled "Favorite Videos", with around 35 links to Youtube videos. The links are named things like "Video (Worry)" and "Video (Squirting)" and the videos all feature a man named Leo giving dubious advice and promoting his life-coaching website. Here's one of the suspect videos. There does not appear to be any connection between the content of the videos and my friend or her magazine. I also posted to the Security StackExchange to ask why someone would do this and what the security risks are to her. What I want to know here is, what can she do to stop them? To be clear she doesn't want the domain name back. She just doesn't want her name and copyrighted material used deceptively. Also, what (if anything) could she have done when shutting down her website to avoid this happening?

• How to manage own bots at the server?

  - by Nikolay Kuznetsov

  There is a game server and people can play in game rooms of 2, 3 or 4. When a client connects to server he can send a request specifying a number of people or range he wants to play with. One of this value is valid: {2-4, 2-3, 3-4, 2, 3, 4} So the server maintains 3 separate queues for game room with 2, 3 and 4 people. So we can denote queues as #2, #3 and #4. It work the following way. If a client sends request, 3-4, then two separate request are added to queues #3 and #4. If queue #3 now have 3 requests from different people then game room with 3 players is created, and all other requests from those players are removed from all queues. Right now not many people are online simultaneously, so they apply for a game wait for some time and quit because game does not start in a reasonable time. That's a simple bot for beginning has been developed. So there is a need to patch server code to run a bot, if some one requests a game, but humans are not online. Input: request from human {2-4, 2-3, 3-4, 2, 3, 4} Output: number of bots to run and time to wait for each before connecting, depending on queues state. The problem is that I don't know how to manage bots properly at the server? Example: #3 has 1 request and #4 has 1 request Request from user is {3,4} then server can add one bot to play game with 3 people or two bots to play game of 4. Example: #3 has 1 request and #4 has 2 requests Request from user is {3,4} then in each case just one bot is needed so game with 4 players is more preferrable.

• Oracle Flashback Technology - Webcast 9th June 2010

  - by Alex Blyth

  Hi All Here are the details for webcast on Oracle Flashback Technologies on Wednesday (9th June 2010) beginning at 1.30pm (Sydney, Australia Time). The Oracle Database architecture leverages the unique technological advances in the area of database recovery due to human errors. Oracle Flashback Technology provides a set of new features to view and rewind data back and forth in time. The Flashback features offer the capability to query historical data, perform change analysis, and perform self-service repair to recover from logical corruptions while the database is online. With Oracle Flashback Technology, you can indeed undo the past! Oracle9i introduced Flashback Query to provide a simple, powerful and completely non-disruptive mechanism for recovering from human errors. It allows users to view the state of data at a point in time in the past without requiring any structural changes to the database. Oracle Database 10g extended the Flashback Technology to provide fast and easy recovery at the database, table, row, and transaction level. Flashback Technology revolutionizes recovery by operating just on the changed data. The time it takes to recover the error is now equal to the same amount of time it took to make the mistake. Oracle 10g Flashback Technologies includes Flashback Database, Flashback Table, Flashback Drop, Flashback Versions Query, and Flashback Transaction Query. Flashback technology can just as easily be utilized for non-repair purposes, such as historical auditing with Flashback Query and undoing test changes with Flashback Database. Oracle Database 11g introduces an innovative method to manage and query long-term historical data with Flashback Data Archive. This release also provides an easy, one-step transaction backout operation, with the new Flashback Transaction capability. Webcast is at http://strtc.oracle.com (IE6, 7 & 8 supported only)Conference ID for the webcast is 6690835Conference Key: flashbackEnrollment is required.

• Do you have a contract between the Product Owner and the Team?

  - by Martin Hinshelwood

  Working in Scrum it is useful to define a Sprint Contract between the Product Owner (PO) and the implementation Team. Doing this helps to improve common understanding in, and sometimes to enforce, the relationship between the PO and the Team. This is simply an agreement between the PO for one Sprint and is not really a commercial contract and should be confirmed via an e-mail at the beginning of every Sprint. “The implementation team agrees to do its best to deliver an agreed on set of features (scope) to a defined quality standard by the end of the sprint. (Ideally they deliver what they promised, or even a bit more.) The Product Owner agrees not to change his instructions before the end of the Sprint.” - Agile Project management (http://agilesoftwaredevelopment.com/blog/peterstev/10-agile-contracts#Sprint) Each of the Sprints in a Scrum project can be considered a mini-project that has Time (Sprint Length), Scope (Sprint Backlog), Quality (Definition of Done) and Cost (Team Size*Sprint Length). Only the scope can vary and this is measured every sprint. Figure: Good Example, the product owner should reply to the team and commit to the contract This Rule has been added to SSW’s Rules to better Scrum with TFS   Technorati Tags: SSW,Scrum,SSW Rules
