• ASP.Net MVC: Areas and controllers

  - by xamlnotes

  Areas are a great feature of MVC now. The let you put common code into an Area and then its segregated from other code. That makes it really easy to put those common feature in one spot and not have the interfere with other code. So today I was working on a new area and starting to test code in it. But the controller method could not be found. Testing the routes and all of the names proved no help either. So I am banging my head against the wall. Then I took a peak at one of the existing controllers in another Area in the same app. Looked similar, but … There was a Namespaceat the top of that controller with that Area in the Namespace.  I had copied my controller in from somewhere else and therefore it did not have the Namespace there.   I put in the right Namespace and cool, it worked right away. So add that to your list when testing.

• Is this kind of Design by Contract useless?

  - by Charlie Pigarelli

  I've just started informatics university and I'm attending a programming course about C(++). The programming professor prefers to teach very few things (in 3 month we have just reached the functions topic) and connect every topic with a type of programming design that somehow is similar to the Design by Contract design. Basically what he ask us to do is to write every exercise with comments Pre-conditions, Post-conditions and Invariants that should prove the correctness of each program we write. But this doesn't make any sense to me. I mean, ok: maybe writing down your thoughts prevent you from doing some mistakes, but if this is all an abstract thing, then if your program intuition is wrong you'll write your program wrong and then you'll also write pre and post conditions wrong probably auto convincing your self about its correctness. Most of the time, both me and other students have written programs that seemed ok and that had correct pre and post condition too. But at the moment of testing it was just completely wrong. I had some experience before this course of programming and I had written a lot of line of code before and I found myself comfortably with just writing a program and unit test it. It take less time to accomplish and is less "abstract" than just thinking about what every single piece of your program should do in every case (which is kinda like mentally testing it). Finally, all this pre and post conditions takes me like 80% of the total time of the exercise. It's harder to think about putting down this pre and post correct than to write the program itself. Since we are like the only course of the only university probably in the entire world that makes this things, could someone please tell me how should I manage this thing? Am I right thinking that this doesn't worth anything? Should I change university? (there are like double of the people attending that course and it seems that usually very few people passes the exam the first year). Should I convince myself it's method is right?

• Generalized Ajax function [migrated]

  - by TecBrat

  Not sure if this question will be considered "off topic". If it is, I'll remove it, but: I hadn't see this yet so I wrote it and would like to know if this is a good approach to it. Would anyone care to offer improvements to it, or point me to an example of where someone else has already written it better? function clwAjaxCall(path,method,data,asynch) { var xmlhttp; if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } if(asynch) { xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { //alert(xmlhttp.responseText); //var newaction=xmlhttp.responseText; //alert('Action becomes '+newaction); return xmlhttp.responseText; } } } if(method=='GET'){path=path+"/?"+data;} xmlhttp.open(method,path,asynch); if(method=='GET'){xmlhttp.send();}else{xmlhttp.send(data);} if (!asynch){return xmlhttp.responseText;} } I then called it like Just Testing <script type="text/javascript" src="/mypath/js/clwAjaxCall.js"></script> <script type="text/javascript"> document.write("<br>More Testing"); document.write(clwAjaxCall("http://www.mysite.com",'GET',"var=val",false)); </script>

• Staying OO and Testable while working with a database

  - by Adam Backstrom

  What are some OOP strategies for working with a database but keeping thing testable? Say I have a User class and my production environment works against MySQL. I see a couple possible approaches, shown here using PHP: Pass in a $data_source with interfaces for load() and save(), to abstract the backend source of data. When testing, pass a different data store. $user = new User( $mysql_data_source ); $user-load( 'bob' ); $user-setNickname( 'Robby' ); $user-save(); Use a factory that accesses the database and passes the result row to User's constructor. When testing, manually generate the $row parameter, or mock the object in UserFactory::$data_source. (How might I save changes to the record?) class UserFactory { static $data_source; public static function fetch( $username ) { $row = self::$data_source->get( [params] ); $user = new User( $row ); return $user; } } I have Design Patterns and Clean Code here next to me, but I'm struggling to find applicable concepts.

• How do I speed up XML parsing operation?

  - by absentx

  I currently have a php script set up to do some xml parsing. Sometimes the script is set as an on page include and other times it is accessed via an ajax call. The problem is the load time for this particular page is very long. I started to think that the php I had written to find what I need in the XML was written poorly and my script is very resource intense. After much research and testing the problem is indeed not my scripting (well perhaps you could consider it a problem with my scripting), but it looks like it takes a long time to load the particular xml sources. My code is like such: $source_recent = 'my xml feed'; $source_additional = 'the other feed I need'; $xmlstr_recent = file_get_contents($source_recent); $feed_recent = new SimpleXMLElement($xmlstr_recent); $xmlstr_additional = file_get_contents($source_additional); $feed_additional = new SimpleXMLElement($xmlstr_additional); In all my testing, the above code is what takes the time, not the additional processing I do below. Is there anyway around this or am I at the mercy of the load time of the xml URL's? One crazy thought I had to get around it is to load the xml contents into a db every so often, then just query the db for what I need. Thoughts? Ideas?

• MySQL – Export the Resultset to CSV file

  - by Pinal Dave

  In SQL Server, you can use BCP command to export the result set to a csv file. In MySQL too, You can export data from a table or result set as a csv file in many methods. Here are two methods. Method 1 : Make use of Work Bench If you are using Work Bench as a querying tool, you can make use of it’s Export option in the result window. Run the following code in Work Bench SELECT db_names FROM mysql_testing; The result will be shown in the result windows. There is an option called “File”. Click on it and it will prompt you a window to save the result set (Screen shot attached to show how file option can be used). Choose the directory and type out the name of the file. Method 2 : Make use of OUTFILE command You can do the export using a query with OUTFILE command as shown below SELECT db_names FROM mysql_testing INTO OUTFILE 'C:/testing.csv' FIELDS ENCLOSED BY '"' TERMINATED BY ';' ESCAPED BY '"' LINES TERMINATED BY '\r\n'; After the execution of the above code, you can find a file named testing.csv in C drive of the server.

• How Visual Studio 2010 and Team Foundation Server enable Compliance

  - by Martin Hinshelwood

  One of the things that makes Team Foundation Server (TFS) the most powerful Application Lifecycle Management (ALM) platform is the traceability it provides to those that use it. This traceability is crucial to enable many companies to adhere to many of the Compliance regulations to which they are bound (e.g. CFR 21 Part 11 or Sarbanes–Oxley.)   From something as simple as relating Tasks to Check-in’s or being able to see the top 10 files in your codebase that are causing the most Bugs, to identifying which Bugs and Requirements are in which Release. All that information is available and more in TFS. Although all of this tradability is available within TFS you do need to understand that it is not for free. Well… I say that, but if you are using TFS properly you will have this information with no additional work except for firing up the reporting. Using Visual Studio ALM and Team Foundation Server you can relate every line of code changes all the way up to requirements and back down through Test Cases to the Test Results. Figure: The only thing missing is Build In order to build the relationship model below we need to examine how each of the relationships get there. Each member of your team from programmer to tester and Business Analyst to Business have their roll to play to knit this together. Figure: The relationships required to make this work can get a little confusing If Build is added to this to relate Work Items to Builds and with knowledge of which builds are in which environments you can easily identify what is contained within a Release. Figure: How are things progressing Along with the ability to produce the progress and trend reports the tractability that is built into TFS can be used to fulfil most audit requirements out of the box, and augmented to fulfil the rest. In order to understand the relationships, lets look at each of the important Artifacts and how they are associated with each other… Requirements – The root of all knowledge Requirements are the thing that the business cares about delivering. These could be derived as User Stories or Business Requirements Documents (BRD’s) but they should be what the Business asks for. Requirements can be related to many of the Artifacts in TFS, so lets look at the model: Figure: If the centre of the world was a requirement We can track which releases Requirements were scheduled in, but this can change over time as more details come to light. Figure: Who edited the Requirement and when There is also the ability to query Work Items based on the History of changed that were made to it. This is particularly important with Requirements. It might not be enough to say what Requirements were completed in a given but also to know which Requirements were ever assigned to a particular release. Figure: Some magic required, but result still achieved As an augmentation to this it is also possible to run a query that shows results from the past, just as if we had a time machine. You can take any Query in the system and add a “Asof” clause at the end to query historical data in the operational store for TFS. select <fields> from WorkItems [where <condition>] [order by <fields>] [asof <date>] Figure: Work Item Query Language (WIQL) format In order to achieve this you do need to save the query as a *.wiql file to your local computer and edit it in notepad, but one imported into TFS you run it any time you want. Figure: Saving Queries locally can be useful All of these Audit features are available throughout the Work Item Tracking (WIT) system within TFS. Tasks – Where the real work gets done Tasks are the work horse of the development team, but they only as useful as Excel if you do not relate them properly to other Artifacts. Figure: The Task Work Item Type has its own relationships Requirements should be broken down into Tasks that the development team work from to build what is required by the business. This may be done by a small dedicated group or by everyone that will be working on the software team but however it happens all of the Tasks create should be a Child of a Requirement Work Item Type. Figure: Tasks are related to the Requirement Tasks should be used to track the day-to-day activities of the team working to complete the software and as such they should be kept simple and short lest developers think they are more trouble than they are worth. Figure: Task Work Item Type has a narrower purpose Although the Task Work Item Type describes the work that will be done the actual development work involves making changes to files that are under Source Control. These changes are bundled together in a single atomic unit called a Changeset which is committed to TFS in a single operation. During this operation developers can associate Work Item with the Changeset. Figure: Tasks are associated with Changesets   Changesets – Who wrote this crap Changesets themselves are just an inventory of the changes that were made to a number of files to complete a Task. Figure: Changesets are linked by Tasks and Builds   Figure: Changesets tell us what happened to the files in Version Control Although comments can be changed after the fact, the inventory and Work Item associations are permanent which allows us to Audit all the way down to the individual change level. Figure: On Check-in you can resolve a Task which automatically associates it Because of this we can view the history on any file within the system and see how many changes have been made and what Changesets they belong to. Figure: Changes are tracked at the File level What would be even more powerful would be if we could view these changes super imposed over the top of the lines of code. Some people call this a blame tool because it is commonly used to find out which of the developers introduced a bug, but it can also be used as another method of Auditing changes to the system. Figure: Annotate shows the lines the Annotate functionality allows us to visualise the relationship between the individual lines of code and the Changesets. In addition to this you can create a Label and apply it to a version of your version control. The problem with Label’s is that they can be changed after they have been created with no tractability. This makes them practically useless for any sort of compliance audit. So what do you use? Branches – And why we need them Branches are a really powerful tool for development and release management, but they are most important for audits. Figure: One way to Audit releases The R1.0 branch can be created from the Label that the Build creates on the R1 line when a Release build was created. It can be created as soon as the Build has been signed of for release. However it is still possible that someone changed the Label between this time and its creation. Another better method can be to explicitly link the Build output to the Build. Builds – Lets tie some more of this together Builds are the glue that helps us enable the next level of tractability by tying everything together. Figure: The dashed pieces are not out of the box but can be enabled When the Build is called and starts it looks at what it has been asked to build and determines what code it is going to get and build. Figure: The folder identifies what changes are included in the build The Build sets a Label on the Source with the same name as the Build, but the Build itself also includes the latest Changeset ID that it will be building. At the end of the Build the Build Agent identifies the new Changesets it is building by looking at the Check-ins that have occurred since the last Build. Figure: What changes have been made since the last successful Build It will then use that information to identify the Work Items that are associated with all of the Changesets Changesets are associated with Build and change the “Integrated In” field of those Work Items . Figure: Find all of the Work Items to associate with The “Integrated In” field of all of the Work Items identified by the Build Agent as being integrated into the completed Build are updated to reflect the Build number that successfully integrated that change. Figure: Now we know which Work Items were completed in a build Now that we can link a single line of code changed all the way back through the Task that initiated the action to the Requirement that started the whole thing and back down to the Build that contains the finished Requirement. But how do we know wither that Requirement has been fully tested or even meets the original Requirements? Test Cases – How we know we are done The only way we can know wither a Requirement has been completed to the required specification is to Test that Requirement. In TFS there is a Work Item type called a Test Case Test Cases enable two scenarios. The first scenario is the ability to track and validate Acceptance Criteria in the form of a Test Case. If you agree with the Business a set of goals that must be met for a Requirement to be accepted by them it makes it both difficult for them to reject a Requirement when it passes all of the tests, but also provides a level of tractability and validation for audit that a feature has been built and tested to order. Figure: You can have many Acceptance Criteria for a single Requirement It is crucial for this to work that someone from the Business has to sign-off on the Test Case moving from the  “Design” to “Ready” states. The Second is the ability to associate an MS Test test with the Test Case thereby tracking the automated test. This is useful in the circumstance when you want to Track a test and the test results of a Unit Test designed to test the existence of and then re-existence of a a Bug. Figure: Associating a Test Case with an automated Test Although it is possible it may not make sense to track the execution of every Unit Test in your system, there are many Integration and Regression tests that may be automated that it would make sense to track in this way. Bug – Lets not have regressions In order to know wither a Bug in the application has been fixed and to make sure that it does not reoccur it needs to be tracked. Figure: Bugs are the centre of their own world If the fix to a Bug is big enough to require that it is broken down into Tasks then it is probably a Requirement. You can associate a check-in with a Bug and have it tracked against a Build. You would also have one or more Test Cases to prove the fix for the Bug. Figure: Bugs have many associations This allows you to track Bugs / Defects in your system effectively and report on them. Change Request – I am not a feature In the CMMI Process template Change Requests can also be easily tracked through the system. In some cases it can be very important to track Change Requests separately as an Auditor may want to know what was changed and who authorised it. Again and similar to Bugs, if the Change Request is big enough that it would require to be broken down into Tasks it is in reality a new feature and should be tracked as a Requirement. Figure: Make sure your Change Requests only Affect Requirements and not rewrite them Conclusion Visual Studio 2010 and Team Foundation Server together provide an exceptional Application Lifecycle Management platform that can help your team comply with even the harshest of Compliance requirements while still enabling them to be Agile. Most Audits are heavy on required documentation but most of that information is captured for you as long a you do it right. You don’t even need every team member to understand it all as each of the Artifacts are relevant to a different type of team member. Business Analysts manage Requirements and Change Requests Programmers manage Tasks and check-in against Change Requests and Bugs Testers manage Bugs and Test Cases Build Masters manage Builds Although there is some crossover there are still rolls or “hats” that are worn. Do you thing this is all achievable? Have I missed anything that you think should be there?

• Exalytics Increases Customer Revenue, and Saves Time, Risk & Cost

  - by Mike.Hallett(at)Oracle-BI&EPM

  We are getting some great proof point stories now from our customers who are succeeding with the Exalytics in-memory system for OBI and Essbase.  See below for some recent testimony: San Diego Unified School District Harnesses Attendance, Procurement, and Operational Data with Oracle Exalytics, Generating $4.4 Million in Savings: according to independent assessment by Mainstay Salire, the district is on track to achieve substantial benefits from the Oracle Exalytics solution, including an $8.25 million increase in attendance revenue, $75,000 a year savings in operational efficiencies, and $1 million in hardware cost avoidance. NilsonGroup chooses Oracle Exalytics In-Memory Machine as their solution to access critical data to keep its stores competitive with real-time Mobile BI: it took only “3 days to get up and running” with Exalytics.  Video Nykredit, in the Danish Financial Sector, describes their experiences from testing the Exalytics Business Intelligence Machine: “it was up and running within 4 days” with “more intuitive dashboards” and “up to 70x better performance” and “cheaper maintenance and lower total cost of ownership”. Video Sodexo chose Oracle Exalytics as their business analytics platform; accelerating Essbase “more than 8x” performance for more than 2,000 Excel-addin users, “significantly changing how people in information management now deal with data”.  Video Polk, Savvis, Nykredit, and Key Energy describe testing of the Oracle Exalytics In-Memory Machine: to “reach more users than we ever have before”, “to fly through the data without impeding the analytic process”, “drive our enterprise groups into this tool instead of having departmental solutions”, and the “advanced visualisation this product enables”.  Video

• SQL Server 2008 R2: These are a Few of My Favorite Things

  - by smisner

  This month's T-SQL Tuesday is hosted by Jorge Segarra (blog | twitter) who decided that we should write about our favorite new feature in SQL Server 2008 R2. The majority of my published works concentrates on Reporting Services, so the obious answer for me is about favorite new features is...Reporting Services. I can't pick just one thing in Reporting Services, so instead I thought I'd compile a list of my posts of the new features in Reporting Services 2008 R2: Map Wizard for spatial data (The World is But a Stage) Pagination features (I've Got Your Page Number) Lookup functions (Look Up, Look Down, Look All Around - Part I, Part II, Part III) Test Connection button (Testing, Testing 1-2-3) Conditional formatting based on format, i.e. RenderFormat (As You Like It) And I wrote an overview of the business intelligence features in SQL Server 2008 R2 for Microsoft Press in the free e-book, Introducing Microsoft SQL Server 2008 R2, if you're curious about what else is new in both the BI platform as well as the relational engine.

• Advantages and Disadvantages of the Waterfall Methodology

  In my personal opinion I believe the waterfall method is one of the worst methodologies to use when developing larger systems because it leaves is no room for mistakes. As the name implies the waterfall methodology does not allow  for projects to go back up stream to recover from design errors, missing and/or limited requirements. In addition, hidden bugs are not usually found until the testing phase. This can prove to be very costly and time consuming to the developer and the client. According to NCycles.com, the waterfall methodology structures a project into separate stages with defined deliverables from each phase. Define Design Code Test Implement Document and Maintain The advantages found by Ncycle.com to this methodology are: Ease in analyzing potential changes  Ability to coordinate larger teams, even if geographically distributed Can enable precise dollar budget Less total time required from Subject Matter Experts The disadvantages found by Ncycle.com to this methodology are: Lack of flexibility Hard to predict all needs in advance Intangible knowledge lost between hand-offs Lack of team cohesion Design flaws not discovered until the Testing phase References: NCycles.com  (2002).

• Fuzzing for Security

  - by Sylvain Duloutre

  Yesterday, I attended an internal workshop about ethical hacking. Hacking skills like fuzzing can be used to quantitatively assess and measure security threats in software.  Fuzzing is a software testing technique used to discover coding errors and security loopholes in software, operating systems or networks by injecting massive amounts of random data, called fuzz, to the system in an attempt to make it crash. If the program contains a vulnerability that can leads to an exception, crash or server error (in the case of web apps), it can be determined that a vulnerability has been discovered.A fuzzer is a program that generates and injects random (and in general faulty) input to an application. Its main purpose is to make things easier and automated.There are typically two methods for producing fuzz data that is sent to a target, Generation or Mutation. Generational fuzzers are capable of building the data being sent based on a data model provided by the fuzzer creator. Sometimes this is simple and dumb as sending random bytes, swapping bytes or much smarter by knowing good values and combining them in interesting ways.Mutation on the other hand starts out with a known good "template" which is then modified. However, nothing that is not present in the "template" or "seed" will be produced.Generally fuzzers are good at finding buffer overflow, DoS, SQL Injection, Format String bugs etc. They do a poor job at finding vulnerabilites related to information disclosure, encryption flaws and any other vulnerability that does not cause the program to crash.  Fuzzing is simple and offers a high benefit-to-cost ratio but does not replace other proven testing techniques.What is your computer doing over the week-end ?

• SPUtility.SendMail and the 2048 Character Limit

  - by Damon

  We were in the middle of testing a web part responsible for gathering information from visitors to our Client's website and emailing it to someone responsible for responding to the request.  During testing, however, it was brought to our attention that the message was cutting off at 2048 characters.  Now, 2048 is one of those numbers that is usually indicative of some computational limit, but I was hopeful that Microsoft had thought through the possibility of emailing more than 2048 characters from SharePoint.  Luckily I was right. and wrong. As it turns out, SPUtility.SendMail is not limited to any specific character limit as far as I can tell.  However, each LINE of text that you send via SendMail cannot exceed 2048 characters.  Since we were sending an HTML email it was constructed entirely without line breaks, far exceeding the 2048 character limit and ultimately helping to educate me about this obscure technical limitation whose only benefit thus far is offering me something to rant about on my blog.  The fix is simple, just put in a carriage return and a line break often enough to avoid going past the 2048 character limit.  I'm sure someone can present a great technical reason for the 2048 character limit, but it seems fairly arbitrary since the "\r\n" that got appended to the string are ultimately just characters too.

• Php profiling on production server or other options

  - by absentx

  Alright I need some help here. I am commonly asked to speed up certain sections of some websites that I program for. I have yet to be able to figure out how to use a good php diagnosis/profiling tool. Some things to consider: The sites I am working on are already built, getting a testing server set up locally is just a huge pain..I have to rewrite include paths and just so many things. This is a results oriented deal and spending days to get a site fully working on a testing platform so I can debug one page probably isn't an option. I can write tons of php, but I have no clue how to interact or mess with servers. So every tutorial I read about setting up xdebug or xhprof all seem to involve getting something installed on a production server that I don't have access to or have no clue how to work with. So are there any solutions out there that will show me where my php is slow without having to do all sorts of server stuff that I just don't know how to do? Xhprof seems to be the closest to useable for me but from what I can tell it still has to be installed on a server. If anyone can just point me in the right direction on this I would be very grateful. Maybe getting these things put on the server isn't a big deal...but I have never interacted with server command lines or anything like that. I suppose I should start sometime but I really have no idea where to start. Plus I realize that profiling on a live platform is not the greatest idea either but I feel I am in a tough spot. I have speed issues to solve and setting up a local environment while a great idea, just doesn't seem real practical at the moment.

• Enterprise Manager Grid Control licencelése

  - by Lajos Sárecz

  Gyakran kapok kérdéseket az Oracle Enterprise Manager Grid Control licencelésével kapcsolatban, ezért az alábbiakban igyekszem összefoglalni a legfontosabb információkat. Az alábbi ismerteto nem teljes köru, mivel számos olyan termék van (Data Masking, Real Application Testing, Real User Experience Insight, Application Testing Suite), melyek kapcsolódnak az Enterprise Manager-hez, azonban licencelésük másképp muködik. Az Enterprise Manager licenceléssel kapcsolatban az elsodleges információ forrás a Licensing Information doksi. A legfontosabb információk: - A Grid Control keretrendszer (Agent-ek és a konzol az alapfunkciókkal - lásd késobb) önmagában ingyenes, sot restricted-use licencet tartalmaz Oracle Database-re, amennyiben azt csak az Oracle Management Repository céljára használják. Fontos, hogy ez nem tartalmaz egyéb Oracle Database opciókat, mint például a RAC! Hasonlóképpen az Oracle WebLogic Server is kizárólagosan az Oracle Management Server kiszolgálására használható ingyenesen, de fürtözés nélkül. - A Grid Control alapfunkcionalitása: Discovery, Groups, Job Scheduling, Real time availability, Performance & monitoring, Target Home Pages, Administration, Console alerts - Az alapfunkcionalitás felügyelt termékektol függoen bovítheto Management Pack, Plug-in és Connector termékekkel. Alapvetoen ezek licencelése mindig a monitorozott, felügyelt termék licenceléséhez kell, hogy igazodjon. Tehát például ha 2 adatbázis szerverre szeretnénk Diagnostic Pack-ek használni, akkor mindkettore kell CPU vagy NUP (Named User Plus) licencet vásárolni, attól függoen az adatbázis maga milyen licenccel rendelkezik. Megjegyzem ezt a konkrét Management Pack-ek kizárólag Enterprise Edition Database esetén lehet alkalmazni. - Számos fizetos funkció külön telepítés nélkül is elérheto a Grid Control felületén (ugyanez igaz Database Control-ra és Fusion Middleware Control-ra is). Hogy elkerüljük a licenc sértést, érdemes ellenorízni hogy az adott környezetben mely Management Pack-ek használata került bekapcsolásra. Ezt a Grid Control Setup menüjében a Management Pack Access almenüben tehetjük meg legegyszerubben. Részleteseb leírás itt található. Database Diagnostic és Tuning Pack adatbázis szintu kikapcsolására is lehetoség van, hogy parancssorból se lehessen használni oket, errol korábban már írtam. Az egyes management termékek USD ára megtalálható az árlistában. Ha valami fontos kimaradt, várom a kérdéseket, hozzászólásokat, és igény szerint bovítem a fentieket.

• Non-Obvious Topics to Learn for Game Development

  - by ashes999

  I've been writing games for around 10 years now (from QBasic to C# and everything in-between). I need to start stretching my skills into different areas. What are other, surprising topics I should read up on? Expected topics would include the usual suspects: Programming language of your choice Scripting language Source control Project management (or Agile) Graphics API Maybe some AI (A* path-finding?) Physics (projectile physics) Unit testing (automated testing) I'm looking for more esoteric topics; things that you don't expect to need to know, but if you do know them, they make a difference. This could include things like: Art skills (drawing, lighting, colouring, layout, etc.) Natural language processing The physics of sound (sound-waves, doppler effect, etc.) Personally, I feel that having technical art skills (eg. can make decent art-work if you can only come up with ideas; or, following Photoshop/GIMP tutorials) was the most beneficial for me. This is not intended to be an open-ended question; I'm looking for specific skills that helped you and you expect will continue to benefit you in the short- and long-term.

• How do you manage a complexity jump?

  - by glenatron

  It seems an infrequent but common experience that sometimes you're working on a project and suddenly something turns up unexpectedly, throws a massive spanner in the works and ramps up the complexity a whole lot. For example, I was working on an application that talked to SOAP services on various other machines. I whipped up a prototype that worked fine, then went on to develop a regular front end and generally get everything up and running in a nice, fairly simple and easy to follow fashion. It worked great until we started testing across a wider network and suddenly pages started timing out as the latency of the connections and the time required to perform calculations on remote machines resulted in timed out requests to the soap services. It turned out that we needed to change the architecture to spin requests out onto their own threads and cache the returned data so it could be updated progressively in the background rather than performing calculations on a request by request basis. The details of that scenario are not too important - indeed it's not a great example as it was quite forseeable and people who have written a lot of apps of this type for this type of environment might have anticipated it - except that it illustrates a way that one can start with a simple premise and model and suddenly have an escalation of complexity well into the development of the project. What strategies do you have for dealing with these types of functional changes whose need arises - often as a result of environmental factors rather than specification change - later on in the development process or as a result of testing? How do you balance between avoiding the premature optimisation/ YAGNI/ overengineering risks of designing a solution that mitigates against possible but not necessarily probable issues as opposed to developing a simpler and easier solution that is likely to be as effective but doesn't incorporate preparedness for every possible eventuality?

• Is it a bad idea to release software on the night before Christmas?

  - by Conor

  We're about to go live with a new version of our system. It's getting really close to Christmas. I work in a very small company. Everyone will be on leave or sporadically available over the next week or so. I've argued with my boss that this is very risky and that we should go live in the new year when everyone is back and when we can provide full support. He is unflinching - he argues that we need to go live sooner - so that we can get new users and more revenue which we need. The number of new users will be minor amount over the next week or so. There has been a decent amount of system testing performed on the system. However a new live system, in my experience, needs a lot of care and attention in the first few days. Am I being pessimistic or realistic? Update - January: The system did not go live over Christmas. Ongoing system testing revealed various problems. So no support issues to deal with. Still preparing for release...

• Fixed Assets Recommended Patch Collections

  - by Cindy A B-Oracle

  After the introduction of the Recommended Patch Collections (RPCs) in late 2012, Fixed Assets development has released an RPC about every six months.  You may recall that an RPC is a collection of recommended patches consolidated into a single, downloadable patch, ready to be applied.  The RPCs are created with the following goals in mind: Stability:  Address issues that occur often and interfere with the normal completion of crucial business processes, such as period close--as observed by Oracle Development and Global Customer Support. Root Cause Fixes:  Deliver a root cause fix for data corruption issues that delay period close, normal transaction flow actions, performance, and other issues. Compact:  While bundling a large number of important corrections, the file footprint is kept as small as possible to facilitate uptake and minimize testing. Reliable:  Reliable code with multiple customer downloads and comprehensive testing by QA, Support and Proactive Support.  There has been a revision to the RPC release process for spring 2014.  Instead of releasing product-specific RPCs, development has released a 12.1.3 RPC that is EBS-wide.  This EBS RPC includes all product-recommended patches along with their dependencies. To find out more about this EBS-wide RPC, please review Oracle E-Business Suite Release 12.1.3+ Recommended Patch Collection 1 (RPC1) (Doc ID 1638535.1).

• Finishing an iteration early

  - by f1dave

  I'd like some input on this on those working with agile methodologies... A current project is finding that development on our planned user stories is finishing some time before the end of the iteration, and that the testing effort and business acceptance is what's actually dragging us out longer towards the end. This means that the devs in question have spare time, and they're essentially going out to the iteration+1 backlog and starting work on cards there before our current iteration cards are 'done'. As iteration manager, I want to put a stop to this - I want a more team-orientated approach where the group takes ownership of getting all the cards done, as opposed to "Well, dev's done so what do I dev next?" The problem I face is convincing the team of this. On one hand, I understand why the devs don't want to test the code they've written (there are unit tests they write of course, but the manual testing to be done could be influenced by their bias). The team sees working ahead as making our next iterations easier, because a lot of the work is done before we start. I see this as screwing with the whole system of planning/actuals - but it's difficult to convince the team as to why this matters. What advice can you guys and girls give? How do we stop devs reaching ahead? What should they be doing instead? How much of a problem is this in the scheme of things, if things are still getting done?

• Overwhelmed by complex C#/ASP.NET project in Visual Studio 2008

  - by Darren Cook

  I have been hired as a junior programmer to work on projects that extend existing functionality in a very large, complex solution. The code base consists of C#, ASP.NET, jQuery, javascript, html and xml. I have some knowledge of all these in addition to fair knowledge of object-oriented programming and its fundamental concepts of inheritance, abstraction, polymorphism and encapsulation. I can follow code up through its base classes, interfaces, abstract classes and understand a large part of the code that I read while doing this. However, this solution is so humongous and so many things get tied together whenever I navigate through the code that I feel absolutely overwhelmed. I often find myself unable to fully follow everything that is going on with objects being serialized, large amounts of C# and javascript operating on the same pages and methods being called from template files that consist mainly of markup. I love learning about code, but trying to deal with this really stresses me out. Additionally, I do know that a significant amount of unit testing has been done but I know nothing about unit testing or how to utilize it. Any advice anyone could offer me regarding dealing with a large code base while using Visual Studio 2008 would be greatly appreciated. Are there tools that I can use to help get a handle on what is going on? Perhaps there are things even in Visual Studio that I am not aware of. How can I follow the code to low level functionality in order to get a better grasp of what is going on at a high level?

• MvcReportViewer v.0.4.0 is available!

  - by Ilya Verbitskiy

  Originally posted on: http://geekswithblogs.net/ilich/archive/2014/06/04/mvcreportviewer-v.0.4.0-is-available.aspxToday I released new version of MvcReportViewer. This release contains mostly bug fixes reported by library users. I am glad to see that Open Source model works and people try to contribute to the project! Thank you everybody for your bug repots and help with the project. Version 0.4.0 Added support for ASP.NET MVC 5 Removed jQuery dependency. I have not tested it on IE8 or earlier versions. Any help with testing is welcome! Fixed problem with SSRS keep-alive cookies. Keep-alive cookies are issued every time a report is opened during a browser session. Many people don't restart their browsers and in my case, Chrome doesn't get rid of the cookie session data on close - had to manually delete them for the reports to start working again. I added KeepSessionAlive control settings to manage SSRS keep-alive behavior. It is set to false by default to fix Bad Request 400: Request Too Long issue. You can find usage example in Fluent.cshtml. Fixed the bug when ReportViewer Control parameters was not parsed when ShowParameterPrompts parameter had not been set. Changed public static MvcReportViewerIframe MvcReportViewer method to use IEnumerable<KeyValuePair<string, object>> reportParameters instead of simple object. The reason is users reported that they mostly use multiple report parameters’ values. Added support for SSRS hosted on Windows Azure. Users should set MvcReportViewer.IsAzureSSRS property to true in Web.config to use Windows Azure authentication. I do not have Windows Azure SSRS and build the code using http://msdn.microsoft.com/en-us/library/gg552871.aspx#Authentication article. It would be nice if somebody from community tested the change or provided me a test report on Windows Azure for testing purposes.

• Happy Day! VS2010 SP1, Project Server Integration, Load Test Feature Pack

  - by Aaron Kowall

  Microsoft released a PILE of Visual Studio goodness today: Visual Studio 2010 SP1(Including TFS SP1) Finally done with remembering which GDR packs, KB Patches, etc need to be installed with a new VS/TFS 2010 deployment.  Just grab the SP1.  It’s available today for MSDN Subscribers and March 10th for public download. TFS-Project Server Integration Feature Pack MSDN Subscribers got another little treat today with the TFS-Project Server integration feature pack.  We can now get project rollups and portfolio level management with Project Server yet still have the tight developer interaction with TFS.  Finally we can make the PMO happy without duplicate entry or MS Project gymnastics. Visual Studio Load Test Feature Pack This is a new benefit for Visual Studio 2010 Ultimate subscribers.  Previously there was a limit to Ultimate Load Testing of 250 virtual users. If you needed more, you had to buy virtual user license packs.  No more.  Now your Visual Studio Ultimate license allows you to simulate as many virtual users as you need!!  This is HUGE in improving adoption of regular load testing for development projects. All the Details are available from Soma’s blog. Technorati Tags: VS2010,TFS,Load Test
