  • Running Teamsite User Admin tool IWUSERADM.exe from ASP.NET

    - by Narendra Tiwari
    It has really been a head scratching task for me. I 've tried many options but nothing worked. Finally I found a workaround on google to achive this by TaskScheduler. PROBLEM When we run Teamsite user administration command line tool IWUSERADM.exe though ASP.Net it gives following error: Application popup: cmd.exe - Application Error : The application failed to initialize properly (0xc0000142). Click on OK to terminate the application. CAUSE No specific cause, it seems to be a bug, supposed to be resolved with this Microsoft patch http://support.microsoft.com/kb/960266. and there is nothing related to permission issue, y web application is impersonated with an administrator account. off course running a bat file from dmin account is a potential secury threat but for this scenario lets conifned our discussion to run the command line tool. RESOLUTION I have not tried this patch as I have not permitted to run this patch on server. Below are the steps to achive the requirement. 1/ Create a batch file which runs the IWUSERADM.exe.         echo - Add Teamsite User    CD E:\Appli\GN00\iw-home\bin    iwuseradm add-user %1 2/ Temporarily create a schedule task and run  the .bat file by scheduled task by ASP.Net code using TaskScheduler http://www.codeproject.com/KB/cs/tsnewlib.aspx. 3/ Here is the function: private int AddTeamsiteUser(string strBatchFilePath, string strUser) { //Get a ScheduledTasks object for the local computer. ScheduledTasks st = new ScheduledTasks(); // Create a task Task t; try{ t = st.CreateTask("~AddTeamsiteUser"); } catch { throw new Exception("Schedule Task ~AddTeamsiteUser already exist."); }    t.SetAccountInformation(yourLogin, yourPassword); //Set the account under which the task should run.  t.Save();  t.Run(); Thread.Sleep(2000); //for sync issue //Remove the scheduled task st.DeleteTask("~AddTeamsiteUser"); return t.ExitCode;   Below are few resources related to the above scenario:- - Task Scheduler Class Library for .NET  http://www.codeproject.com/KB/cs/tsnewlib.aspx - Run a .BAT file from ASP.NET  http://codebetter.com/blogs/brendan.tompkins/archive/2004/05/13/13484.aspx - TaskScheduler Class  http://msdn.microsoft.com/en-us/library/system.threading.tasks.taskscheduler.aspx - Application Hangs whle running iwuseradm.exe through ASP.Net  http://bytes.com/topic/asp-net/answers/733098-system-diagnostics-process-hangs     t.ApplicationName = strBatchFilePath; t.Parameters = strUser; t.Comment = "Adding user to Teamsite Application"

  • Qt's future in the light of Nokia-Microsoft partnership

    - by Shinnok
    In case you missed it, a lot has happened in the last two day that could potentially impact the Qt framework, for the worse. :-( It will impact the mobile sector in several and probably not currently acknowledged ways, for sure. It started yesterday with Nokia's CEO Stephen Elop internal letter depicting Nokia sitting on a burning platform and the need for a big and aggressive shift in business. A day later, at the Nokia World conference, Nokia announced the partnership with Microsoft , which at the moment resumes to Nokia adopting the Windows Phone 7 platform and development environment, dumping Symbian along the road and tagging Meego as R&D(a pretty dangerous keyword if you ask me), as for Maemo/N900 series i guess it's bye bye for good. I know what you're thinking but no, Qt is not going to be ported to the Window Phone platform. And i'm also scared about this. You can watch the Elop & Ballmer joint press release here. Now after reading this huge thread on the Qt-interest mailing list i can't help but wonder, what is the future of Qt at Nokia, now that they aren't focused(at all?) on Qt anymore(remember the full focus switch on Qt as main development framework for all Nokia products(including Symbian, yes) back in October?). I love Qt, in my opinion it is the only true cross-platform application development framework and one of the few to make C++ development a joy(to the extent possible) and good things has happened to the framework and considerable momentum while under Nokia, thus i am wondering, what are the chances that Qt might suffer a slow death at Nokia after this? Yes i know about KDE.org and the fact that Qt is easily spawnable, but i still feel uneasy. It also must be horrible for all of the efforts either by Nokia employees or third parties that have gone into Symbian and all of the Ovi Store Symbian/Qt content and business and why not, Maemo/Meego. There are also massive layouts planned, i suspect Symbian techs and Qt? I'd love to hear your input on this? Is Qt future safe&proof? LE: The question as been gradually revised, improved and better referenced, thus you might want to throw a quick re-read to see what you might have missed.

  • The Politics of Junk Filtering

    - by mikef
    If the national postal service, such as the Royal Mail in the UK, were to go through your letters and throw away all the stuff it considered to be junk instead of delivering it to you, you might be rather pleased until you discovered that it took a too liberal decision about what was junk. Catalogs you'd asked for? Junk! Requests from charities? Who needs them! Parcels from competing carriers? Toss them away! The possibility for abuse for an agency that was in a monopolistic position is just too scary to tolerate. After all, the postal service could charge 'consultancy fees' to any sender who wanted to guarantee that his stuff got delivered, or they could even farm this out to other companies. Because Microsoft Outlook is just about the only email client used by the international business community in the west, its' SPAM filter is the final arbiter as to what gets read. My Outlook 2007, set to the default settings, junks all the perfectly innocent email newsletters that I subscribe to. Whereas Google Mail, Yahoo, and LIVE are all pretty accurate in detecting spam, Outlook makes all sorts of silly mistakes. The documentation speaks techno-babble about 'advanced heuristics', but the result boils down to an inaccurate mess. The more that Microsoft fiddles with it, the stickier the mess. To make matters worse, it still lets through obvious spam. The filter is occasionally updated along with other automatic 'security' updates you opt for automatic updates. As an editor for a popular online publication that provides a newsletter service, this is an obvious source of frustration. We follow all the best-practices we know about. We ensure that it is a trivial task to opt out of receiving it. We format the newsletter to the requirements of the Service Providers. We follow up, and resolve, every complaint. As a result, it gets delivered. It is galling to discover that, after all that effort, Outlook then often judges the contents to be junk on a whim, so you don't get to see it. A few days ago, Microsoft published the PST file format specification, under pressure from a European Union interoperability investigation by ECIS (the European Committee for Interoperable Systems). The objective was that other applications could then access existing PST files so as to migrate from existing Outlook installations to other solutions. Joaquín Almunia, the current competition commissioner, should now turn his attention to the more subtle problems of Microsoft Outlook. The Junk problem seems to have come from clumsy implementation of client-side spam filtering rather than from deliberate exploitation of a monopoly on the desktop email client for businesses, but it is a growing problem nonetheless.

  • virtual host not working in windows7 xampp

  • Inspiring a co-worker to adopt better coding practices?

    - by Aaronaught
    In the Handling my antiquated coworker question, various people discussed strategies for dealing with coworkers who are unwilling to integrate their workflow with the team's. I'd like, if possible, to learn some strategies for "teaching" a coworker who is merely ignorant of modern techniques and tools, and possibly a little apathetic. I've started working with a programmer who until recently has been working in relative isolation, in a different part of the company. He has extensive domain knowledge and most importantly he has demonstrated good problem-solving skills, something which many candidates seem to lack. However, the actual (C#) code I've seen is a throwback to the VB6 days. Procedural structure, Hungarian notation, global variables (abuse of static), no interfaces, no tests, non-use of Generics, throwing System.Exception... you get the idea. This programmer is a fair bit older than I am and, by first impressions at least, doesn't actively seek positive change. I'm not going to say resistant to change, because I think that is largely an issue of how the topic gets broached, and I want to be prepared. Programmers tend to be stubborn people, and going in with guns blazing and instituting rip-it-to-shreds code reviews and strictly-enforced policies is very likely not going to produce the end result that I want. If this were a new hire, a junior programmer, I wouldn't think twice about taking a "mentor" stance, but I'm extremely wary of treating an experienced employee as a clueless newbie (which he's not - he just hasn't kept pace with certain advancements in the field). How might I go about raising this developer's code quality standard the Dale Carnegie way, through gentle persuasion and non-material incentives? What would be the best strategy for effecting subtle, gradual changes, without creating an adversarial situation? Have other people - especially lead developers - been in this type of situation before? Which strategies were successful at stimulating interest and creating a positive group dynamic? Which strategies weren't successful and would be better to avoid? Clarifications: I really feel that several people are answering based on personal feelings without actually reading all of the details of the question. Please note the following, which should have been implied but I am now making explicit: This coworker is only my "senior" by virtue of age. I never said that his title, sphere of influence, or years at the organization exceed mine, and in fact, none of those things are true. He's a LOB programmer who's been absorbed into the main development shop. That's it. I am not a new hire, junior programmer, or other naïve idiot with grand plans to transform the company overnight. I am basically in charge of the software process, but as many who've worked as "leads" will know, responsibilities don't always correlate precisely with the org chart. I'm not asking people how to get my way, come hell or high water. I could do that if I wanted to, with the net result being that this person would become resentful and/or quit. Please try to understand that I am looking for a social, cooperative method of driving change. The mention of "...global variables... no tests... throwing System.Exception" was intended to demonstrate that the problems are not just superficial or aesthetic. Practices that may work for relatively small CRUD apps do not necessarily work for large enterprise apps, and in fact, none of the code so far has actually passed the integration tests. Please, try to take the question at face value, accept that I actually know what I'm talking about, and either answer the question that I actually asked or move on. P.S. My sincerest gratitude to those who -did- offer constructive advice rather than arguing with the premise. I'm going to leave this open for a while longer as I'm hoping to hear more in the way of real-world experiences.

  • Running Multiple Queries in Oracle SQL Developer

    - by thatjeffsmith
    There are two methods for running queries in SQL Developer: Run Statement Run Statement, Shift+Enter, F9, or this button Run Script No grids, just script (SQL*Plus like) ouput is fine, thank you very much! What’s the Difference? There are some obvious differences between the two features, the most obvious being the format of the output delivered. But there are some other, more subtle differences here, primarily around fetching. What is Fetch? After you run send your query to Oracle, it has to do 3 things: Parse Execute Fetch Technically it has to do at least 2 things, and sometimes only 1. But, to get the data back to the user, the fetch must occur. If you have a 10 row query or a 1,000,000 row query, this can mean 1 or many fetches in groups of records. Ok, before I went on the Fetch tangent, I said there were two ways to run statements in SQL Developer: Run Statement Run statement brings your query results to a grid with a single fetch. The user sees 50, 100, 500, etc rows come back, but SQL Developer and the database know that there are more rows waiting to be retrieved. The process on the server that was used to execute the query is still hanging around too. To alleviate this, increase your fetch size to 500. Every query ran will come back with the first 500 rows, and rows will be continued to be fetched in 500 row increments. You’ll then see most of your ad hoc queries complete with a single fetch. Scroll down, or hit Ctrl+End to force a full fetch and get all your rows back. Run Script Run Script runs the contents of the worksheet (or what’s highlighted) as a ‘script.’ What does that mean exactly? Think of this as being equivalent to running this in SQL*Plus: @my_script.sql; Each statement is executed. Also, ALL rows are fetched. So once it’s finished executing, there are no open cursors left around. The more obvious difference here is that the output comes back formatted as plain old text. Run one or more commands plus SQL*Plus commands like SET and SPOOL The Trick: Run Statement Works With Multiple Statements! It says ‘run statement,’ but if you select more than one with your mouse and hit the button – it will run each and throw the results to 1 grid for each statement. If you mouse hover over the Query Result panel tab, SQL Developer will tell you the query used to populate that grid. This will work regardless of what you have this preference set to: DATABASE – WORKSHEET – SHOW QUERY RESULTS IN NEW TABS Mind the fetch though! Close those cursors by bring back all the records or closing the grids when you’re done with them.

  • Returning null vs Throwing exceptions

    - by Svish
    Is in a bit of disagreement with a more experienced developer on this issue, and was wondering what you guys here think about this. Environment is Java, EJB 3, services, etc. The code I wrote calls a service to get things and to create things. Problem was that I got null pointer exceptions in places that didn't make sense. For example when I asked the service to create an object, I got null back. And when I tried to look up an object with an id I knew existed, I still got null back. Was like it was ignoring me. Spent some time trying to figure out what was wrong in my code (since I'm less experienced I usually assume I have messed up). Turns out the reason was security. If the user principal using my service didn't have the right permissions to use the service I called from my service, then that service simply returned null. The services that are here already are usually not documented either, so this is just something you have to know... somehow... So here is the thing: I mean that this is rather confusing as a developer interacting with this service. To me it would make much more sense if that service thew an exception which would tell me that hey, you don't have the proper permissions to get info about this thing or to create this new thing. I would then immediately know why my service wasn't working as expected. However, he argued that asking is not wrong. Exceptions should only be thrown when there is an error and asking for a thing is not an error. Even if you don't have permission to "see" that the thing you asked for. The things are often looked up in a GUI by users and for those users not having the right permissions, these things simply "do not exist". So, in short: Asking is not wrong, hence no exception. Get methods return null because to those users those things "doesn't exist". Create methods return null because nothing was created, since the user wasn't allowed to create anything. So, what do you guys think? Is this normal and/or good practice? I prefer exceptions as I prefer throwing and catching exceptions because I find it much easier to know what's going on. So I would for example also prefer to throw a NotFoundException if you asked for an id which didn't exist, rather than returning null. Anyways, just curious to what others think about this as I'm not the most experienced developer yet.

  • The Diabolical Developer: What You Need to Do to Become Awesome

    - by Tori Wieldt
    Wearing sunglasses and quite possibly hungover, Martijn Verburg's evil persona provided key tips on how to be a Diabolical Developer. His presentation at TheServerSide Java Symposium was heavy on the sarcasm and provided lots of laughter. Martijn insisted that developers take their power back and get rid of all the "modern fluff" that distract developers.He provided several key tips to become a Diabolical Developer:*Learn only from yourself. Don't read blogs or books, and don't attend conferences. If you must go on forums, only do it display your superiority, answer as obscurely as possible.*Work aloneBest coding happens when you alone in your room, lock yourself in for days. Make sure you have a gaming machine in with you.*Keep information to yourselfKnowledge is power. Think job security. Never provide documentation. *Make sure only you can read your code.Don't put comments in your code. Name your variables A,B,C....A1,B1, etc.If someone insists you format your in a standard way, change a small section and revert it back as soon as they walk away from your screen. *Stick to what you knowStay on Java 1.3. Don't bother learning abstractions. Write your application in a single file. Stuff as much code into one class as possible, a 30,000-line class is fine. Makes it easier for you to read and maintain.*Use Real ToolsNo "fancy-pancy" IDEs. Real developers only use vi.*Ignore FadsThe cloud is massively overhyped. Mobile is a big fad for young kids.The big, clunky desktop computer (with a real keyboard) will return.Learn new stuff only to pad your resume. Ajax is great for that. *Skip TestingTest-driven development is a complete waste of time. They sent men to the moon without unit tests.Just write your code properly in the first place and you don't need tests.*Compiled = Ship ItUser acceptance testing is an absolute waste of time. *Use a Single ThreadDon't use multithreading. All you need to do is throw more hardware at the problem.*Don't waste time on SEO.If you've written the contract correctly, you are paid for writing code, not attracting users.You don't want a lot of users, they only report problems. *Avoid meetingsFake being sick to avoid meetings. If you are forced into a meeting, play corporate bingo.Once you stand up and shout "bingo" you will kicked out of the meeting. Job done.Follow these tips and you'll be well on your way to being a Diabolical Developer!

  • Difference between EJB Persist & Merge operation

    - by shantala.sankeshwar
    This article gives the difference between EJB Persist & Merge operations with scenarios.Use Case Description Users working on EJB persist & merge operations often have this question in mind " When merge can create new entity as well as modify existing entity,then why do we have 2 separate operations - persist & merge?" The reason is very simple.If we use merge operation to create new entity & if the entity exists then it does not throw any exception,but persist throws exception if the entity already exists.Merge should be used to modify the existing entity.The sql statement that gets executed on persist operation is insert statement.But in case of merge first select statement gets executed & then update sql statement gets executed.Scenario 1: Persist operation to create new Emp recordLet us suppose that we have a Java EE Web Application created with Entities from Emp table & have created session bean with data control. Drop Emp Object(Expand SessionEJBLocal->Constructors under Data Controls) as ADF Parameter form in jspx pageDrop persistEmp(Emp) as ADF CommandButton & provide #{bindings.EmpIterator.currentRow.dataProvider} as the value for emp parameter.Then run this page & provide values for Emp,click on 'persistEmp' button.New Emp record gets created.So when we execute persist operation only insert sql statement gets executed :INSERT INTO EMP (EMPNO, COMM, HIREDATE, ENAME, JOB, DEPTNO, SAL, MGR) VALUES (?, ?, ?, ?, ?, ?, ?, ?)    bind => [2, null, null, e2, null, 10, null, null]Scenario 2: Merge operation to modify existing Emp recordLet us suppose that we have a Java EE Web Application created with Entities from Emp table & have created session bean with data control.Drop empFindAll() Object as ADF form on jspx page.Drop mergeEmp(Emp) operation as commandButton & provide #{bindings.EmpIterator.currentRow.dataProvider} as the value for emp parameter.Then run this page & modify values for Emp record,click on 'mergeEmp' button.The respective Emp record gets modified.So when we execute merge operation select & update sql statements gets executed :SELECT EMPNO, COMM, HIREDATE, ENAME, JOB, DEPTNO, SAL, MGR FROM EMP WHERE (EMPNO = ?) bind => [7566]UPDATE EMP SET ENAME = ? WHERE (EMPNO = ?) bind => [KINGS, 7839]

  • SQL SERVER – What is SSAS Tabular Data model and Why to use it – Part 2

    - by Pinal Dave
    In my last article, I talked about the basics of tabular data model and why use it. Then I demonstrated step by step creation of a basic tabular model project. In this part I’m going to throw some light on how to create measures and analyses in excel. If you look at the tabular project closely, you will notice that we have not defined any measure yet. So, in the first step we will define the measure first.  Open the solution and select the column you want to define as a measure. Then, click on the summation icon on the toolbar. You will see the aggregated results at the bottom of that column. You have also other choices as well like average, min, max, count and distinct count. After creating the required measures, we need to analyze our data in excel. To do this, click on the excel icon in the upper left corner of the toolbar. This will open your analysis in excel. Notice the pivot table field list here. I have highlighted the measures that we created in the earlier step. Now, we can use these measures in our analysis Now, we have to put the required fields in their respective places as column labels, row labels, Values and Report filter for analysis. See below snapshot for details, it shows region wise sales on a yearly basis You can even apply filters on the above analysis by placing the slicer field in report filter. In our example, we will take an English product name as a filter. You can use the filter as depicted in the below snapshot. Optionally, you can also use the slider to filter data more interactively. Further to improve our analysis, we can insert pivot charts That’s all for this time, in my next post I’m going to show in detail about how to create hierarchies, perspectives, KPI’s  and many more features.

  • What Counts For A DBA: ESP

    - by Louis Davidson
    Now I don’t want to get religious here, and I’m not going to, but what I’m going to describe in this ‘What Counts for a DBA’ installment sometimes feels like magic. Often  I will spend hours thinking about the solution to a design issue or coding problem, working diligently to try to come up with a solution and then finally just give up with the feeling that I’m not even qualified to be a data entry clerk, much less a data architect.  At this point I often take a walk (or sometimes a nap), and then it hits me. I realize that I have the answer just sitting in my brain, ready to implement.  This phenomenon is not limited to walks either; it can happen almost any time after I stop my obsession about a problem. I call this phenomena ESP (or Extra-Sensory Programming.)  Another term for this could be ‘sleeping on it’, and while the idiom tends to mean to let time pass to actively think about a problem, sleeping on a problem also lets you relax and let your brain do the work. I first noticed this back in my college days when I would play video games for hours on end. We would get stuck deep in some dungeon unable to find a way out, playing for days on end until we were beaten down tired. Once we gave up and walked away, the solution would usually be there waiting for one of us before we came back to play the next day.  Sometimes it would be in the form of a dream, and sometimes it would just be that the problem was now easy to solve when we started to play again.  While it worked great for video games, it never occurred when I studied English Literature for hours on end, or even when I worked for the same sort of frustrating hours attempting to solve a homework problem in Calculus.  I believe that the difference was that I was passionate about the video game, and certainly far less so about homework where people used the word “thou” instead of “you” or x to represent a number. This phenomenon occurs somewhat more often in my current work as a professional data programmer, because I am very passionate about SQL and love those aspects of my career choice.  Every day that I get to draw a new data model to solve a customer issue, or write a complex SELECT statement to ferret out the answer to a complex data question, is a great day. I hope it is the same for any reader of this blog.  But, unfortunately, while the day on a whole is great, a heck of a lot of noise is generated in work life. There are the typical project deadlines, along with the requisite project manager sitting on your shoulders shouting slogans to try to make you to go faster: Add in office politics, and the occasional family issues that permeate the mind, and you lose the ability to think deeply about any problem, not to mention occasionally forgetting your own name.  These office realities coupled with a difficult SQL problem staring at you from your widescreen monitor will slowly suck the life force out of your body, making it seem impossible to solve the problem This is when the walk starts; or a nap. Maybe you hide from the madness under your desk like George Costanza hides from Steinbrenner on Seinfeld.  Forget about the problem. Free your mind from the insanity of the problem and your surroundings. Then let your training and education deep in your brain take over and see if it will passively do the rest for you. If you don’t end up with a solution, the worst case scenario is that you have a bit of exercise or rest, and you won’t have heard the phrase “better is the enemy of good enough” even once…which certainly will do your brain some good. Once you stop expecting whipping your brain for information, inspiration may just strike and instead of a humdrum solution you find a solution you hadn’t even considered, almost magically. So, my beloved manager, next time you have an urgent deadline and you come across me taking a nap, creep away quietly because I’m working, doing some extra-sensory programming.

  • Upgrading Code from 2007 to 2010

    - by MOSSLover
    So I’ve been doing some upgrades just to see if things will work from 2007 to 2010.  So far most of the stuff I want works, but obviously there are some things that break.  Did you guys know that in 2007 you could add a webpart to the view pages for lists and libraries without losing the toolbar?  In 2010 the ribbon disappears every time you add a webpart.  So if you are using Scot Hillier’s Codeplex project to hide buttons it will not work the same way, because the ribbon is going to disappear altogether. I have also learned another reason why standalone installations are the bane of my existence.  Nine times out of ten the installation is done using Network Service as the application pool account.  You are wondering why is this bad?  Well, let’s just say the site collection administrator with local admin rights wants to attach the IIS Worker process and debug say a webpart.  Visual Studio 2010 will throw a nasty error that tells you that you are not an administrator.  You will say, but I am an administrator?  I have all the correct group permissions on the server and on SQL and in SharePoint.  Then you will go in and decide let’s add my own admin account just to see if I can attach the debugger and you will notice that works properly.  So the morale of the story is create a separate account on your development environment to run all the SharePoint Services and such.  You don’t need to go all out and create the best practices amount of accounts if it’s just your dev environment.  I would at least create one single account to run all your SharePoint process (Services, SQL, and App Pool).  Also, don’t run a standalone install unless you want to kill kittens (this is a quote from Todd Klindt).  We love kittens they are cute and awesome.  Besides you learn more if you click Complete and just skip standalone.  You will learn how to setup SQL Server 2008 and you will learn how to configure your environment.  It will help you in the long run.  So I have ranted enough for today I figure these are enough tidbits for you this time around.  The two of you who read my blog and I know some of you are friends who don’t understand SharePoint.  I might as well have just done “wahwahwahwah” in Charlie Brown adult speak.  Thanks for reading as usual.  I’ll catch you all when I complain more about the upgrade process and share more tidbits, which will inevitably become a presentation at a conference or two.

  • What is the SharePoint Action Framework and Why do I need it ?

    - by SAF
    For those out there that are a little curious as to whether SAF is any use to your organisation, please read this FAQ.  What is SAF ? SAF is free to use. SAF is the "SharePoint Action Framework", it was built by myself and Hugo (plus a few others along the way). SAF is written entirely in C# code available from : http://saf.codeplex.com.   SAF is a way to automate SharePoint configuration changes. An Action is a command/class/task/script written in C# that performs a unit of execution against SharePoint such as "CreateWeb"  or "AddLookupColumn". A SAF Macro is collection of one or more Actions. SAF Macro can be run from Msbuild, a Feature, StsAdm or common plain old .Net code. Parameters can be passed to a Macro at run-time from a variety of sources such as "Environment Variable", "*.config", "Msbuild Properties", Feature Properties, command line args, .net code. SAF emits lots of trace statements at run-time, these can be viewed using "DebugView". One Action can pass parameters to another Action. Parameters can be set using Expression Syntax such as "DateTime.Now".  You should consider SAF is you suffer from one of the following symptoms... "Our developers write lots of code to deploy changes at release time - it's always rushed" "I don't want my developers shelling out to Powershell or Stsadm from a Feature". "We have loads of Console applications now, I have lost track of where they are, or what they do" "We seem to be writing similar scripts against SharePoint in lots of ways, testing is hard". "My scripts often have lots of errors - they are done at the last minute". "When something goes wrong - I have no idea what went wrong or how to solve it". "Our Features get stuck and bomb out half way through - there no way to roll them back". "We have tons of Features now - I can't keep track". "We deploy Features to run one-off tasks" "We have a library of reusable scripts, but, we can only run it in one way, sometimes we want to run it from MSbuild and a Feature". "I want to automate the deployment of changes to our development environment". "I would like to run a housekeeping task on a scheduled basis"   So I like the sound of SAF - what's the problems ?  Realistically, there are few things that need to be considered: Someone on your team will need to spend a day or 2 understanding SAF and deciding exactly how you want to use it. I would suggest a Tech Lead, SysAdm or SP Architect will need to download it, try out the examples, look through the unit tests. Ask us questions. Although, SAF can be downloaded and set to go in a few minutes, you will still need to address issues such as - "Do you want to execute your Macros in MsBuild or from a Feature ?" You will need to decide who is going to do your deployments - is it each developer to themself, or do you require a dedicated Build Manager ? As most environments (Dev, QA, Live etc) require different settings (e.g. Urls, Database names, accounts etc), you will more than likely want to define these and set a properties file up for each environment. (These can then be injected into Saf at run-time). There may be no Action to solve your particular problem. If this is the case, suggest it to us - we can try and write it, or write it yourself. It's very easy to write a new Action - we have an approach to easily unit test it, document it and author it. For example, I wrote one to deploy  a WSP in 2 hours the other day. Alternatively, Saf can also call Stsadm commands and Powershell scripts.   Anyway, I do hope this helps! If you still need help, or a quick start, we can also offer consultancy around SAF. If you want to know more give us a call or drop an email to [email protected]

  • Is there a language or design pattern that allows the *removal* of object behavior or properties in a class hierarchy?

    - by Sebastien Diot
    A well-know shortcoming of traditional class hierarchies is that they are bad when it comes to model the real world. As an example, trying to represent animals species with classes. There are actually several problems when doing that, but one that I never saw a solution to is when a sub-class "looses" a behavior or properties that was defined in a super-class, like a penguin not being able to fly (there are probably better examples, but that's the first one that comes to my mind, having seen "Madagascar 2" recently). On the one hand, you don't want to define for every property and behavior some flag that specifies if it is at all present, and check it every time before accessing that behavior or property. You would just like to say that birds can fly, simply and clearly, in the Bird class. But then it would be nice if one could define "exceptions" afterward, without having to use some horrible hacks everywhere. This often happens when a system has been productive for a while. You suddenly find an "exception" that doesn't fit in the original design at all, and you don't want to change a large portion of your code to accommodate it. So, is there some language or design patterns that can cleanly handle this problem, without requiring major changes to the "super-class", and all the code that uses it? Even if a solution only handle a specific case, several solutions might together form a complete strategy. [EDIT] Forgot about the Liskov Substitution Principle. That is why you can't do it. Assuming you define "traits/interfaces" for all major "feature groups", you can freely implement traits in different branches of the hierarchy, like the Flying trait could be implemented by Birds, and some special kind of squirrels and fish. So my question could amount to "How could I un-implement a trait?" If your super-class is a Java Serializable, you have to be one too, even if there is no way for you to serialize your state, for example if you contained a "Socket". So one way to do it is to always define all your traits in pair from the start: Flying and NotFlying (which would throw UnsupportedOperationExceiption, if not checked against). The Not-trait would not define any new interface, and could be simply checked for. Sounds like a "cheap" solution, in particular if used from the start.

  • Shadows shimmer when camera moves

    - by Chad Layton
    I've implemented shadow maps in my simple block engine as an exercise. I'm using one directional light and using the view volume to create the shadow matrices. I'm experiencing some problems with the shadows shimmering when the camera moves and I'd like to know if it's an issue with my implementation or just an issue with basic/naive shadow mapping itself. Here's a video: http://www.youtube.com/watch?v=vyprATt5BBg&feature=youtu.be Here's the code I use to create the shadow matrices. The commented out code is my original attempt to perfectly fit the view frustum. You can also see my attempt to try clamping movement to texels in the shadow map which didn't seem to make any difference. Then I tried using a bounding sphere instead, also to no apparent effect. public void CreateViewProjectionTransformsToFit(Camera camera, out Matrix viewTransform, out Matrix projectionTransform, out Vector3 position) { BoundingSphere cameraViewFrustumBoundingSphere = BoundingSphere.CreateFromFrustum(camera.ViewFrustum); float lightNearPlaneDistance = 1.0f; Vector3 lookAt = cameraViewFrustumBoundingSphere.Center; float distanceFromLookAt = cameraViewFrustumBoundingSphere.Radius + lightNearPlaneDistance; Vector3 directionFromLookAt = -Direction * distanceFromLookAt; position = lookAt + directionFromLookAt; viewTransform = Matrix.CreateLookAt(position, lookAt, Vector3.Up); float lightFarPlaneDistance = distanceFromLookAt + cameraViewFrustumBoundingSphere.Radius; float diameter = cameraViewFrustumBoundingSphere.Radius * 2.0f; Matrix.CreateOrthographic(diameter, diameter, lightNearPlaneDistance, lightFarPlaneDistance, out projectionTransform); //Vector3 cameraViewFrustumCentroid = camera.ViewFrustum.GetCentroid(); //position = cameraViewFrustumCentroid - (Direction * (camera.FarPlaneDistance - camera.NearPlaneDistance)); //viewTransform = Matrix.CreateLookAt(position, cameraViewFrustumCentroid, Up); //Vector3[] cameraViewFrustumCornersWS = camera.ViewFrustum.GetCorners(); //Vector3[] cameraViewFrustumCornersLS = new Vector3[8]; //Vector3.Transform(cameraViewFrustumCornersWS, ref viewTransform, cameraViewFrustumCornersLS); //Vector3 min = cameraViewFrustumCornersLS[0]; //Vector3 max = cameraViewFrustumCornersLS[0]; //for (int i = 1; i < 8; i++) //{ // min = Vector3.Min(min, cameraViewFrustumCornersLS[i]); // max = Vector3.Max(max, cameraViewFrustumCornersLS[i]); //} //// Clamp to nearest texel //float texelSize = 1.0f / Renderer.ShadowMapSize; //min.X -= min.X % texelSize; //min.Y -= min.Y % texelSize; //min.Z -= min.Z % texelSize; //max.X -= max.X % texelSize; //max.Y -= max.Y % texelSize; //max.Z -= max.Z % texelSize; //// We just use an orthographic projection matrix. The sun is so far away that it's rays are essentially parallel. //Matrix.CreateOrthographicOffCenter(min.X, max.X, min.Y, max.Y, -max.Z, -min.Z, out projectionTransform); } And here's the relevant part of the shader: if (CastShadows) { float4 positionLightCS = mul(float4(position, 1.0f), LightViewProj); float2 texCoord = clipSpaceToScreen(positionLightCS) + 0.5f / ShadowMapSize; float shadowMapDepth = tex2D(ShadowMapSampler, texCoord).r; float distanceToLight = length(LightPosition - position); float bias = 0.2f; if (shadowMapDepth < (distanceToLight - bias)) { return float4(0.0f, 0.0f, 0.0f, 0.0f); } } The shimmer is slightly better if I drastically reduce the view volume but I think that's mostly just because the texels become smaller and it's harder to notice them flickering back and forth. I'd appreciate any insight, I'd very much like to understand what's going on before I try other techniques.

  • What information must never appear in logs?

    - by MainMa
    I'm about to write the company guidelines about what must never appear in logs (trace of an application). In fact, some developers try to include as many information as possible in trace, making it risky to store those logs, and extremely dangerous to submit them, especially when the customer doesn't know this information is stored, because she never cared about this and never read documentation and/or warning messages. For example, when dealing with files, some developers are tempted to trace the names of the files. For example before appending file name to a directory, if we trace everything on error, it will be easy to notice for example that the appended name is too long, and that the bug in the code was to forget to check for the length of the concatenated string. It is helpful, but this is sensitive data, and must never appear in logs. In the same way: Passwords, IP addresses and network information (MAC address, host name, etc.)¹, Database accesses, Direct input from user and stored business data must never appear in trace. So what other types of information must be banished from the logs? Are there any guidelines already written which I can use? ¹ Obviously, I'm not talking about things as IIS or Apache logs. What I'm talking about is the sort of information which is collected with the only intent to debug the application itself, not to trace the activity of untrusted entities. Edit: Thank you for your answers and your comments. Since my question is not too precise, I'll try to answer the questions asked in the comments: What I'm doing with the logs? The logs of the application may be stored in memory, which means either in plain on hard disk on localhost, in a database, again in plain, or in Windows Events. In every case, the concern is that those sources may not be safe enough. For example, when a customer runs an application and this application stores logs in plain text file in temp directory, anybody who has a physical access to the PC can read those logs. The logs of the application may also be sent through internet. For example, if a customer has an issue with an application, we can ask her to run this application in full-trace mode and to send us the log file. Also, some application may sent automatically the crash report to us (and even if there are warnings about sensitive data, in most cases customers don't read them). Am I talking about specific fields? No. I'm working on general business applications only, so the only sensitive data is business data. There is nothing related to health or other fields covered by specific regulations. But thank you to talk about that, I probably should take a look about those fields for some clues about what I can include in guidelines. Isn't it easier to encrypt the data? No. It would make every application much more difficult, especially if we want to use C# diagnostics and TraceSource. It would also require to manage authorizations, which is not the easiest think to do. Finally, if we are talking about the logs submitted to us from a customer, we must be able to read the logs, but without having access to sensitive data. So technically, it's easier to never include sensitive information in logs at all and to never care about how and where those logs are stored.

  • What's Old is New Again

    - by David Dorf
    Last night I told my son he could stream music to his tablet "from the cloud" (in this case, the Amazon Cloud).  He paused, then said, "what is the cloud?"  I replied, "a bunch of servers connected to the internet."  Apparently he had visions of something much more magnificent.  Another similar term is "big data."  These marketing terms help to quickly convey topics but are oversimplifications that are open to many interpretations.  At their core, those terms a shiny packages holding recycled ideas. I see many headlines declaring big data changes everything, but it doesn't.  Savvy retailers have been dealing with large volumes of data since the electronic cash register was invented.  But the there have a been a few changes to the landscape that make big data a topic of conversation: 1. Computing power has caught up to storage volumes. Its now possible to more thoroughly analyze the copious volumes of data retailers have been squirreling away.  CPUs are faster, sold state drives more plentiful, and new ways to store and search data are available.  My iPhone is more power than the computer used in the Apollo mission to the moon. 2. Unstructured data is everywhere.  The Web used to be where retailers published product information, but now users are generating the bulk of the content in the form of comments, videos, and "likes."  The variety of information available to retailers is huge, and it meaning difficult to discern. 3. Everything is connected.  Looking at a report from my router, there are no less than 20 active devices on my home network.  We can track the location of mobile phones, tag products with RFID, and set our thermostats (I love my Nest) from a thousand miles away.  Not only is there more data, but its arriving at higher velocity. Careful readers will note the three Vs that help define so-called big data: volume, variety, and velocity. We now have more volume, more variety, and more velocity and different technologies to deal with them.  But at the heart, the objectives are still the same: Informed decisions Accurate forecasts Improved optimizations So don't let the term "big data" throw you off the scent.  Retailers still need to execute on the basics.  But do take a fresh look at the data that's available and the new technologies to process it.  The landscape will continue to change and agile organizations will always be reevaluating their approaches.  You can just add some more weapons to the arsenal.

  • Code review recommendations and Code Smells

    - by Michael Freidgeim
    Some time ago Twitter told that I am similar to Boris Lipschitz . Indeed he is also .Net programmer from Russia living in Australia. I‘ve read his list of Code Review points and found them quite comprehensive. A few points  were not clear for me, and it forced me for a further reading.In particular the statement “Exception should not be used to return a status or an error code.” wasn’t fully clear for me, because sometimes we store an exception as an object with all error details and I believe it’s a valid approach. However I agree that throwing exceptions should be avoided, if you expect to return error as a part of a normal flow. Related link: http://codeutopia.net/blog/2010/03/11/should-a-failed-function-return-a-value-or-throw-an-exception/ Another point slightly puzzled me“If Thread.Sleep() is used, can it be replaced with something else, ei Timer, AutoResetEvent, etc” . I believe, that there are very rare cases, when anyone using Thread.Sleep in any production code. Usually it is used in mocks and prototypes.I had to look further to clarify “Dependency injection is used instead of Service Location pattern”.Even most of articles has some preferences to Dependency injection, there are also advantages to use Service Location. E.g see http://geekswithblogs.net/KyleBurns/archive/2012/04/27/dependency-injection-vs.-service-locator.aspx. http://www.cookcomputing.com/blog/archives/000587.html  refers to Concluding Thoughts of Martin Fowler The choice between Service Locator and Dependency Injection is less important than the principle of separating service configuration from the use of services within an applicationThe post had a link to excellent article Code Smells of Jeff Atwood, but the statement, that “code should not pass a review if it violates any of the  code smells” sound too strict for my environment. In particular, I disagree with “Dead Code” recommendation “Ruthlessly delete code that isn't being used. That's why we have source control systems!”. If there is a chance that not used code will be required in a future, it is convenient to keep it as commented or #if/#endif blocks with appropriate explanation, why it could be required in the future. TFS is a good source control system, but context search in source code of current solution is much easier than finding something in the previous versions of the code.I also found a link to a good book “Clean Code.A.Handbook.of.Agile.Software”

  • Any reliable polygon normal calculation code?

    - by Jenko
    I'm currently calculating the normal vector of a polygon using this code, but for some faces here and there it calculates a wrong normal. I don't really know what's going on or where it fails but its not reliable. Do you have any polygon normal calculation that's tested and found to be reliable? // calculate normal of a polygon using all points var n:int = points.length; var x:Number = 0; var y:Number = 0; var z:Number = 0 // ensure all points above 0 var minx:Number = 0, miny:Number = 0, minz:Number = 0; for (var p:int = 0, pl:int = points.length; p < pl; p++) { var po:_Point3D = points[p] = points[p].clone(); if (po.x < minx) { minx = po.x; } if (po.y < miny) { miny = po.y; } if (po.z < minz) { minz = po.z; } } for (p = 0; p < pl; p++) { po = points[p]; po.x -= minx; po.y -= miny; po.z -= minz; } var cur:int = 1, prev:int = 0, next:int = 2; for (var i:int = 1; i <= n; i++) { // using Newell method x += points[cur].y * (points[next].z - points[prev].z); y += points[cur].z * (points[next].x - points[prev].x); z += points[cur].x * (points[next].y - points[prev].y); cur = (cur+1) % n; next = (next+1) % n; prev = (prev+1) % n; } // length of the normal var length:Number = Math.sqrt(x * x + y * y + z * z); // turn large values into a unit vector if (length != 0){ x = x / length; y = y / length; z = z / length; }else { throw new Error("Cannot calculate normal since triangle has an area of 0"); }

  • Segmentation fault 11 in MacOS X- C++ [migrated]

    - by Marcos Cesar Vargas Magana
    all. I have a "segmentation fault 11" error when I run the following code. The code actually compiles but I get the error at run time. //** Terror.h ** #include <iostream> #include <string> #include <map> using std::map; using std::pair; using std::string; template<typename Tsize> class Terror { public: //Inserts a message in the map. static Tsize insertMessage(const string& message) { mErrorMessages.insert( pair<Tsize, string>(mErrorMessages.size()+1, message) ); return mErrorMessages.size(); } private: static map<Tsize, string> mErrorMessages; } template<typename Tsize> map<Tsize,string> Terror<Tsize>::mErrorMessages; //** error.h ** #include <iostream> #include "Terror.h" typedef unsigned short errorType; typedef Terror<errorType> error; errorType memoryAllocationError=error::insertMessage("ERROR: out of memory."); //** main.cpp ** #include <iostream> #include "error.h" using namespace std; int main() { try { throw error(memoryAllocationError); } catch(error& err) { } } I have kind of debugging the code and the error happens when the message is being inserted in the static map member. An observation is that if I put the line: errorType memoryAllocationError=error::insertMessage("ERROR: out of memory."); inside the "main()" function instead of at global scope, then everything works fine. But I would like to extend the error messages at global scope, not at local scope. The map is defined static so that all instances of "error" share the same error codes and messages. Do you know how can I get this or something similar. Thank you very much.

  • How do software projects go over budget and under-deliver?

    - by Carlos
    I've come across this story quite a few times here in the UK: NHS Computer System Summary: We're spunking £12 Billion on some health software with barely anything working. I was sitting the office discussing this with my colleagues, and we had a little think about. From what I can see, all the NHS needs is a database + middle tier of drugs/hospitals/patients/prescriptions objects, and various GUIs for doctors and nurses to look at. You'd also need to think about security and scalability. And you'd need to sit around a hospital/pharmacy/GPs office for a bit to figure out what they need. But, all told, I'd say I could knock together something with that kind of structure in a couple of days, and maybe throw in a month or two to make it work in scale. * If I had a few million quid, I could probably hire some really excellent designers to make a maintainable codebase, and also buy appropriate hardware to run the system on. I hate to trivialize something that seems to have caused to much trouble, but to me it looks like just a big distributed CRUD + UI system. So how on earth did this project bloat to £12B without producing much useful software? As I don't think the software sounds so complicated, I can only imagine that something about how it was organised caused this mess. Is it outsourcing that's the problem? Is it not getting the software designers to understand the medical business that caused it? What are your experiences with projects gone over budget, under delivered? What are best practices for large projects? Have you ever worked on such a project? EDIT *This bit seemed to get a lot of attention. What I mean is I could probably do this for say, 30 users, spending a few tens of thousands of pounds. I'm not including stuff I don't know about the medical industry and government, but I think most people who've been around programming are familiar with that kind of database/front end kind of design. My point is the NHS project looks like a BIG version of this, with bells and whistles, notably security. But surely a budget millions of times larger than mine could provide this?

  • GUI device for throwing a ball

    - by Fredrik Johansson
    The hero has a ball, which shall be thrown with accuracy in a court on iPhone/iPad. The player is seen from above, in a 2D view. In game play, the player reach is between 1/15 and 1/6 of the height of the iPhone screen. The player will run, and try to outmaneuver his opponent, and then throw the ball at a specific location, which is guarded by the opponent (which is also shown on the screen). The player is controlled by a joystick, and that works ok, but how shall I control the stick? Maybe someone can propose a third control method? I've tried the following two approaches: Joystick: Hero has a reach of 1 meter, and this reach is marked with a semi-opaque circle around the player. The ball can be moved by a joystick. When the joystick is moved south, the ball is moved south within the reach circle. There is a direct coupling with the joystick and the position of the ball. I.e. when the joystick is moved max south, the ball is max south within the player reach. At each touch update the speed is calculated, and the Box2d ball position and ball speed are updated. NB, the ball will never be moved outside the reach as long as the player push the joystick. The ball is thrown by swiping the joystick to make the ball move, and then releasing the joystick. At release, the ball will get a smoothed speed of the joystick. Joystick Problem: The throwing accuracy gets bad, because the joystick can not be that big, and a small movement results in quite a large movement of the ball. If the user does not release before the end of the joystick maximum end point, the ball will stop, and when the user releases the joystick the speed of the ball will be zero. Bad... Touch pad A force is applied to the ball by a sweep on a touchpad. The ball is released when the sweep is ended, or when the ball is moved outside the player reach. As there is no one to one mapping between the swipe and the ball position, the precision can be improved. A large swipe can result in a small ball movement. Touch Pad Problem A touchpad is less intuitive. Users do not seem to know what to do with the touch pad. Some tap the touchpad, and then the ball just falls to the ground. As there is no one-to-one mapping, the ball can be moved outside the reach, and then it will just fall to the ground. It's a bit hard to control the ball, especially if the player also moves.

  • need some concrete examples on user stories, tasks and how they relate to functional and technical specifications

    - by gideon
    Little heads up, Im the only lonely dev building/planning/mocking my project as I go. Ive come up with a preview release that does only the core aspects of the system, with good business value and I've coded most of the UI as dirty throw-able mockups over nicely abstracted and very minimal base code. In the end I know quite well what my clients want on the whole. I can't take agile-ish cowboying anymore because Im completely dis-organized and have no paper plan and since my clients are happy, things are getting more complex with more features and ideas. So I started using and learning Agile & Scrum Here are my problems: I know what a functional spec is.(sample): Do all user stories and/or scenarios become part of the functional spec? I know what user stories and tasks are. Are these kinda user stories? I dont see any Business Value reason added to them. I made a mind map using freemind, I had problems like this: Actor : Finance Manager Can Add a Financial Plan into the system because well thats the point of it? What Business Value reason do I add for things like this? Example : A user needs to be able to add a blog article (in the blogger app) because..?? Its the point of a blogger app, it centers around that feature? How do I go into the finer details and system definitions: Actor: Finance Manager Action: Adds a finance plan. This adding is a complicated process with lots of steps. What User Story will describe what a finance plan in the system is ?? I can add it into the functional spec under definitions explaining what a finance plan is and how one needs to add it into the system, but how do I get to the backlog planning from there? Example: A Blog Article is mostly a textual document that can be written in rich text in the system. To add a blog article one must...... But how do you create backlog list/features out of this? Where are the user stories for what a blog article is and how one adds/removes it? Finally, I'm a little confused about the relations between functional specs and user stories. Will my spec contain user stories in them with UI mockups? Now will these user stories then branch out tasks which will make up something like a technical specification? Example : EditorUser Can add a blog article. Use XML to store blog article. Add a form to add blog. Add Windows Live Writer Support. That would be agile tasks but would that also be part of/or form the technical specs? Some concrete examples/answers of my questions would be nice!!

  • If not now, then when?

It seems like only yesterday that I mentioned the gorillagator, a simple construct of confusion to try to draw attention to my message. In reality, that message was sent over a month ago. During that time, the hours slipped to days and days to weeks. Many exciting things have happened to myself; I'm sure many exciting things have happened to you. I'm also sure that many terrifying things have happened to children and their families. 62 children enter treatment at a Children's Miracle Network Hospital every minute. That's nearly 60,000 children since I sent the last email. To put that number in perspective, that is more than the population of Greenland. If we expand that to the past year, they have been nearly 550,000 children treated. That is almost the population of Huntsville, Decatur, and all their suburbs combined. Over the past 4 years, I have raised a little more than $3,000 for Children's Hospital of Alabama. As a result, I received a call from the organizers of Extra Life thanking me for my dedicated work and informing me that I was the top supporters for Children's Hospital of Alabama ... with my measly three grand. We can do much better than that. It may sound like I'm trying to have fun by playing games for 24 hours. It is more than that. It is me using my time and body as a catalyst. It is me putting my passion to work for a cause. It is me turning my love into something tangible. I have been campaigning and fighting to give these children a chance for years. I have been asking you to help me support these children and families. I've been putting in countless hours of talking to people, impassioned emails, and carefully constructed tweets. I have been fighting with cutting edge, and sometimes expensive, technology to try to provide live streams of my marathons. I yearly put my body through 24 (and, this year, 25) hours of no sleep. I do this to represent the countless hours these families sit awake at their children's side. All I ask is a few minutes on a website and a few dollars. These few minutes and few dollars go a long way help people that are experiencing circumstances that only occur in our nightmares. I also ask that you take one extra step. Forward this plea to those that you know. I can only reach a small fraction of a percentage of the people that may be able to help. Together, we can reach the world. I raise money for Children's Hospital of Alabama. As this message branches out, people may wish to support a hospital closer to their area. I have included a link to the list of people that have dedicated their time and have received no donations. Find someone on the list supporting your local hospital and give them a donation. Let them know that their time and effort are appreciated. Together, we can do something great. Together, we can make a difference. Together, we all stand tall. Thank you. You can get more information at http://www.extra-life.org and http://childrensmiraclenetworkhospitals.org/" My donation page is http://www.extra-life.org/participant/cgardner The list of participants without donations is http://www.extra-life.org/index.cfm?fuseaction=donorDrive.eventParticipantList&page=629&eventID=512
