• Craftsmanship Tour: Day 3 &amp; 4 8th Light

  - by Liam McLennan

  Thursday morning the Illinois public transport system came through for me again. I took the Metra train north from Union Station (which was seething with inbound commuters) to Prairie Crossing (Libertyville). At Prairie Crossing I met Paul and Justin from 8th Light and then Justin drove us to the office. The 8th Light office is in an small business park, in a semi-rural area, surrounded by ponds. Upstairs there are two spacious, open areas for developers. At one end of the floor is Doug Bradbury’s walk-and-code station; a treadmill with a desk and computer so that a developer can get exercise at work. At the other end of the floor is a hammock. This irregular office furniture is indicative of the 8th Light philosophy, to pursue excellence without being limited by conventional wisdom. 8th Light have a wall covered in posters, each illustrating one person’s software craftsmanship journey. The posters are a fascinating visualisation of the similarities and differences between each of our progressions. The first thing I did Thursday morning was to create my own poster and add it to the wall. Over two days at 8th Light I did some pairing with the 8th Lighters and we shared thoughts on software development. I am not accustomed to such a progressive and enlightened environment and I found the experience inspirational. At 8th Light TDD, clean code, pairing and kaizen are deeply ingrained in the culture. Friday, during lunch, 8th Light hosted a ‘lunch and learn’ event. Paul Pagel lead us through a coding exercise using micro-pomodori. We worked in pairs, focusing on the pedagogy of pair programming and TDD. After lunch I recorded this interview with Paul Pagel and Justin Martin. We discussed 8th light, craftsmanship, apprenticeships and the limelight framework. Interview with Paul Pagel and Justin Martin My time at Didit, Obtiva and 8th Light has convinced me that I need to give up some of my independence and go back to working in a team. Craftsmen advance their skills by learning from each other, and I can’t do that working at home by myself. The challenge is finding the right team, and becoming a part of it.

• Woes of a Junior Developer - is it possible to not be cut out for programming?

  - by user575158

  (Let me start off by asking - please be gentle, I know this is subjective, but it's meant to incite discussion and provide information for others. If needed it can be converted to community wiki.) I recently was hired as a junior developer at a company I really like. I started out in the field doing QA and transitioned into more and more development work, which is what I really want to end up doing. I enjoy it, but more and more I am questioning whether I am really any good at it or not. Part of this is still growing into the junior developer role, I know, but how much? What are junior developers to expect, what should they be doing and not doing? What can I do to improve and show my company I am serious about this opportunity? I hate that I am costing them time by getting up to speed. I've been told by others that companies make investments in Junior devs and don't expect them to pay off for a while, but how much of this is true? There's got to be a point when it's apparent whether the investment will pay off or not. So far I've been trying to ask as many questions I can, but I've you've been obsessing over a simple problem for some time and the others know that, there comes a time when it's pretty embarrassing to have to get help after struggling so long. I've also tried to be as open to suggestion as possible and work with others to try to refactor my code, but sometimes this can be hard clashing with various team members' personal opinions (being told by someone to write it one way, and then having someone else make you rewrite it). I often get over-stressed and judge myself too harshly, but I just don't want to have to struggle the rest of my life trying to get things work if I just don't have the talent. In your experience, is programming something that almost everyone can learn, or something that some people just don't get? Do others feel this way, or did you feel that way when starting out? It scares me that I have no other job skills should I be unsuited for having the skills necessary to code well.

• Claims-based Identity Terminology

  - by kaleidoscope

  There are several terms commonly used to describe claims-based identity, and it is important to clearly define these terms. · Identity In terms of Access Control, the term identity will be used to refer to a set of claims made by a trusted issuer about the user. · Claim You can think of a claim as a bit of identity information, such as name, email address, age, and so on. The more claims your service receives, the more you’ll know about the user who is making the request. · Security Token The user delivers a set of claims to your service piggybacked along with his or her request. In a REST Web service, these claims are carried in the Authorization header of the HTTP(S) request. Regardless of how they arrive, claims must somehow be serialized, and this is managed by security tokens. A security token is a serialized set of claims that is signed by the issuing authority. · Issuing Authority & Identity Provider An issuing authority has two main features. The first and most obvious is that it issues security tokens. The second feature is the logic that determines which claims to issue. This is based on the user’s identity, the resource to which the request applies, and possibly other contextual data such as time of day. This type of logic is often referred to as policy[1]. There are many issuing authorities, including Windows Live ID, ADFS, PingFederate from Ping Identity (a product that exposes user identities from the Java world), Facebook Connect, and more. Their job is to validate some credential from the user and issue a token with an identifier for the user's account and  possibly other identity attributes. These types of authorities are called identity providers (sometimes shortened as IdP). It’s ultimately their responsibility to answer the question, “who are you?” and ensure that the user knows his or her password, is in possession of a smart card, knows the PIN code, has a matching retinal scan, and so on. · Security Token Service (STS) A security token service (STS) is a technical term for the Web interface in an issuing authority that allows clients to request and receive a security token according to interoperable protocols that are discussed in the following section. This term comes from the WS-Trust standard, and is often used in the literature to refer to an issuing authority. STS when used from developer point of view indicates the URL to use to request a token from an issuer.

• Oracle collaborates with leading IT vendors on Cloud Management Standards

  - by Anand Akela

  During the last couple of days, two key specifications for cloud management standards have been announced. Oracle collaborated with leading technology vendors from the IT industry on both of these cloud management specifications. One of the specifications focuses "Infrastructure as a Service" ( IaaS )  cloud service model , while the other specification announced today focuses on "Platform as a Service" ( PaaS ) cloud service model. Please see The NIST Definition of Cloud Computing to learn more about IaaS and PaaS . Earlier today Oracle , CloudBees, Cloudsoft, Huawei, Rackspace, Red Hat, and Software AG   announced the Cloud Application Management for Platforms (CAMP) specification that will be submitted to Organization for the Advancement of Structured Information Standards (OASIS) for development of an industry standard, in an effort to help ensure interoperability for deploying and managing applications across cloud environments.  Typical PaaS architecture - Source : CAMP specification The CAMP specification defines the artifacts and APIs that need to be offered by a PaaS cloud to manage the building, running, administration, monitoring and patching of applications in the cloud. Its purpose is to enable interoperability among self-service interfaces to PaaS clouds by defining artifacts and formats that can be used with any conforming cloud and enable independent vendors to create tools and services that interact with any conforming cloud using the defined interfaces. Cloud vendors can use these interfaces to develop new PaaS offerings that will interact with independently developed tools and components. In a separate cloud standards announcement yesterday, the Distributed Management Task Force ( DMTF ), the organization bringing the IT industry together to collaborate on systems management standards development, validation, promotion and adoption, released the new Cloud Infrastructure Management Interface (CIMI) specification. Oracle collaborated with various technology vendors and industry organizations on this specification. CIMI standardizes interactions between cloud environments to achieve interoperable cloud infrastructure management between service providers and their consumers and developers, enabling users to manage their cloud infrastructure use easily and without complexity. DMTF developed CIMI as a self-service interface for infrastructure clouds ( IaaS focus ) , allowing users to dynamically provision, configure and administer their cloud usage with a high-level interface that greatly simplifies cloud systems management. Mark Carlson, Principal Cloud Strategist at Oracle provides more details about CAMP  and CIMI his blog . Stay Connected: Twitter |  Face book |  You Tube |  Linked in |  Newsletter

• .NET Reflector Pro Coming…

  The very best software is almost always originally the creation of a single person. Readers of our 'Geek of the Week' will know of a few of them.  Even behemoths such as MS Word or Excel started out with one programmer.  There comes a time with any software that it starts to grow up, and has to move from this form of close parenting to being developed by a team.  This has happened several times within Red-Gate: SQL Refactor, SQL Compare, and SQL Dependency Tracker, not to mention SQL Backup, were all originally the work of a lone coder, who subsequently handed over the development to a structured team of programmers, test engineers and usability designers. Because we loved .NET Reflector when Lutz Roeder wrote and nurtured it, and, like many other .NET developers, used it as a development tool ourselves, .NET Reflector's progress from being the apple of Lutz's eye to being a Red-Gate team-based development  seemed natural.  Lutz, after all, eventually felt he couldn't afford the time to develop it to the extent it deserved. Why, then, did we want to take on .NET Reflector?  Different people may give you different answers, but for us in the .NET team, it just seemed a natural progression. We're always very surprised when anyone suggests that we want to change the nature of the tool since it seems right just as it is. .NET Reflector will stay very much the tool we all use and appreciate, although the new version will support .NET 4, and will have many improvements in the accuracy of its decompiling. Whilst we've made a lot of improvements to Reflector, the radical addition, which we hope you'll want to try out as well, is '.NET Reflector Pro'. This is an extension to .NET Reflector that allows the debugging of decompiled code using the Visual Studio debugger. It is an add-in, but we'll be charging for it, mainly because we prefer to live indoors with a warm meal, rather than outside in tents, particularly when the winter's been as cold as this one has. We're hoping (we're even pretty confident!) that you'll share our excitement about .NET Reflector Pro. .NET Reflector Pro integrates .NET Reflector into Visual Studio, allowing you to seamlessly debug into third-party code and assemblies, even if you don't have the source code for them. You can now treat decompiled assemblies much like your own code: you can step through them and use all the debugging techniques that you would use on your own code. Try the beta now. span.fullpost {display:none;}

• LLBLGen Pro feature highlights: model views

  - by FransBouma

  (This post is part of a series of posts about features of the LLBLGen Pro system) To be able to work with large(r) models, it's key you can view subsets of these models so you can have a better, more focused look at them. For example because you want to display how a subset of entities relate to one another in a different way than the list of entities. LLBLGen Pro offers this in the form of Model Views. Model Views are views on parts of the entity model of a project, and the subsets are displayed in a graphical way. Additionally, one can add documentation to a Model View. As Model Views are displaying parts of the model in a graphical way, they're easier to explain to people who aren't familiar with entity models, e.g. the stakeholders you're interviewing for your project. The documentation can then be used to communicate specifics of the elements on the model view to the developers who have to write the actual code. Below I've included an example. It's a model view on a subset of the entities of AdventureWorks. It displays several entities, their relationships (both relational and inheritance relationships) and also some specifics gathered from the interview with the stakeholder. As the information is inside the actual project the developer will work with, the information doesn't have to be converted back/from e.g .word documents or other intermediate formats, it's the same project. This makes sure there are less errors / misunderstandings. (of course you can hide the docked documentation pane or dock it to another corner). The Model View can contain entities which are placed in different groups. This makes it ideal to group entities together for close examination even though they're stored in different groups. The Model View is a first-class citizen of the code-generator. This means you can write templates which consume Model Views and generate code accordingly. E.g. you can write a template which generates a service per Model View and exposes the entities in the Model View as a single entity graph, fetched through a method. (This template isn't included in the LLBLGen Pro package, but it's easy to write it up yourself with the built-in template editor). Viewing an entity model in different ways is key to fully understand the entity model and Model Views help with that.

• SQL Server Scripts I Use

  - by Bill Graziano

  When I get to a new client I usually find myself using the same set of scripts for maintenance and troubleshooting.  These are all drop in solutions for various maintenance issues. Reindexing.  I use Michelle Ufford’s (SQLFool) re-indexing script.  I like that it has a throttle and only re-indexes when needed.  She also has a variety of other interesting scripts on her blog too. Server Activity.  Adam Machanic is up to version 10 of sp_WhoIsActive.  It’s a great replacement for the sp_who* stored procedures and does so much more.  If a server is acting funny this is one of the first tools I use. Backups.  Tara Kizer has a great little T-SQL script for SQL Server backups.  Wait Stats.  Paul Randal has a great script to display wait stats.  The biggest benefit for me is that his script filters out at least three dozen wait stats that I just don’t care about (for example LAZYWRITER_SLEEP). Update Statistics.  I didn’t find anything I liked so I wrote a simple script to update stats myself.  The big need for me was that it had to run inside a time window and update the oldest statistics first.  Is there a better one? Diagnostic Queries.  Glenn Berry has a huge collection of DMV queries available.  He also just highlighted five of them including two I really like dealing with unused indexes and suggested indexes. Single Use Query Plans.  Kim Tripp has a script that counts the number of single-use query plans.  This should guide you in whether to enable the Optimize for Adhoc Workloads option in SQL Server 2008. Granting Permissions to Developers.  This is one of those scripts I didn’t even know I needed until I needed it.  Kendra Little wrote it to grant a login read-only permission to all the databases.  It also grants view server state and a few other handy permissions.   What else do you use?  What should I add to my list?

• Tom Cruise: Meet Fusion Apps UX and Feel the Speed

  - by ultan o'broin

  Unfortunately, I am old enough to remember, and now to admit that I really loved, the movie Top Gun. You know the one - Tom Cruise, US Navy F-14 ace pilot, Mr Maverick, crisis of confidence, meets woman, etc., etc. Anyway, one of more memorable lines (there were a few) was: "I feel the need, the need for speed." I was reminded of Tom Cruise recently. Paraphrasing a certain Senior Vice President talking about Oracle Fusion Applications and user experience at an all-hands meeting, I heard that: Applications can never be too easy to use. Performance can never be too fast. Developers, assume that your code is always "on". Perfect. You cannot overstate the user experience importance of application speed to users, or at least their perception of speed. We all want that super speed of execution and performance, and increasingly so as enterprise users bring the expectations of consumer IT into the work environment. Sten Vesterli (@stenvesterli), an Oracle Fusion Applications User Experience Advocate, also addressed the speed point artfully at an Oracle Usability Advisory Board meeting in Geneva. Sten asked us that when we next Googled something, to think about the message we see that Google has found hundreds of thousands or millions of results for us in a split second (for example, About 8,340,000 results (0.23 seconds)). Now, how many results can we see and how many can we use immediately? Yet, this simple message communicating the total results available to us works a special magic about speed, delight, and excitement that Google has made its own in the search space. And, guess what? The Oracle Application Development Framework table component relies on a similar "virtual performance boost", says Sten, when it displays the first 50 records in a table, and uses a scrollbar indicating the total size of the data record set. The user scrolls and the application automatically retrieves more records as needed. Application speed and its perception by users is worth bearing in mind the next time you're at a customer site and the IT Department demands that you retrieve every record from the database. Just think of... Dave Ensor: I'll give you all the rows you ask for in one second. If you promise to use them. (Again, hat tip to Sten.) And then maybe think of... Tom Cruise. And if you want to read about the speed of Oracle Fusion Applications, and what that really means in terms of user productivity for your entire business, then check out the Oracle Applications User Experience Oracle Fusion Applications white papers on the usable apps website.

• Announcing Oracle Enterprise Content Management Suite 11g

  - by [email protected]

  Today Oracle announced Oracle Enterprise Content Management Suite 11g. This is a major release for us, and reinforces our three key themes at Oracle: Complete New in this release - Oracle ECM Suite 11g is built on a single, unified repository. Every piece of content - documents, HTML pages, digital assets, scanned images - is stored and accessbile directly from the repository, whether you are working on websites, creating brand logos, processing accounts payable invoices, or running records and retention functions. It makes complete, end-to-end management of content possible, from the point it enters the organization, through its entire lifecycle. Also new in this release, the installation, access, monitoring and administration of Oracle ECM Suite 11g is centralized. As a complete system, organizations can lower the costs of training and usage by having a centralized source of information that is easily administered. As part of this new unified repository release, Oracle has released a benchmarking white paper that shows the extreme performance and scalability of Oracle ECM Suite. When tested on a two node UCM Server running on Sun Oracle DB Machine Half Rack Hardware with an Exadata storage server, Oracle ECM Suite 11g is able to ingest over 178 million documents per day. Open Oracle ECM Suite 11g is built on a service-oriented architecture. All functions are available through standards-based services calls in Web Services or Java. In this release Oracle unveils Open Web Content Management. Open Web Content Management is a revolutionary approach to web content management that decouples the content management process from the process of creating web applications. One piece of this approach is our one-click web content management. With one click, a web application builder can drag content services into their application, enabling their users to also edit content with just one click. Open Web Content Management is also open because it enables Web developers to add Web content management to new and existing JavaServer Pages (JSP), JavaServer Faces (JSF) and Oracle Application Development Framework (ADF) Faces applications Open content distribution - Oracle ECM Suite 11g offers flexible deployment options with a built-in smart cache so organizations can deliver Web sites or Web applications without requiring Oracle ECM Suite as part of the delivery system Integrated Oracle ECM Suite 11g also offers a series of next generation desktop integrations, providing integrations such as: New MS Office integration with menus to access managed content, insert managed links, and compare managed documents using standard MS Office reviewing tools Automatic identity tagging of documents on download - to help users understand which versions they are viewing and prevent duplicate content items in the content repository. New "smart productivity folders" to show a users workflow inbox, saved searches and checked out content directly from Windows Explorer Drag and drop metadata pop-ups Check in and check out for all file formats with any standard WebDAV server As part of Oracle's Enterprise Application Documents initiative, Oracle Content Management 11g also provides certified application integrations with solution templates You can read the press release here. You can see more assets at the launch center here. You can sign up for the announcement webinar and hear more about the new features here. You can read the benchmarking study here.

• Customization: It’s Wanted in Enterprise Tech Platforms Too

  - by Mike Stiles

  Did you know that every customer service person does their job the exact same way in every business organization?  And did you know that every business organization cares about the exact same metrics? I hope not, because both those things couldn’t be farther from the truth. And if there are different needs and approaches in different enterprises, it stands to reason technology platforms must become increasingly customizable. Oracle Social Cloud sees that coming and is doing something about it, at least in terms of social media management. Today we introduce Social Station, a customizable user experience workspace within the Oracle Social Relationship Management (SRM) platform. We think a lot about customer-centricity and customer experience around here, and we know our own customers are ready to start moving forward in being able to set up their work environments in the ways that work best for them. That kind of thing increases productivity, helps deliver on social objectives faster, and generally just makes life more pleasant. A recent IDG Enterprise report says that enterprises currently investing in more consumerized, easy-to-use technologies experience a 56% increase in employee productivity and a 46% increase in customer satisfaction. Imagine that. When you make it easier and more pleasant for employees to help customers, more customers get helped and everyone ends up happier. So what does this Social Station do and what does it mean, exactly? It’s an innovative move to take some pretty high-end tech (take a bow developers) and simplify it, making things more intuitive: Drag and drop lets you easily build out and personalize your social workspace with different modules. The new Custom Analytics module can mix and match over 120 metrics with thousands of customizable reporting options. You can check constantly refreshed updates and keep a real-time eye on the numbers you’re trying to move. One-click sharing and annotation in the Custom Analytics module improves sharing and collaboration across teams, departments and executives. Multi-view layout helps you leverage social insights by letting you monitor conversations by network, stream, metric, graph type, date range, and relative time period. The Enhanced Calendar is a better visual representation of content, posts, networks and views, letting you easily toggle between functions and views. The Oracle Social Station sets us up to always be developing & launching additional social modules for you, covering areas like content curation, influencer engagement, and command center creation. Oracle Social Cloud Group VP Meg Bear says, “Consumers today have high expectations of their technology application capabilities and usability, and those expectations don’t stop when they enter their workplaces.” In other words, internal enterprise technology platforms must reflect the personalization and customization being called for in consumer products and marketing. “One size fits all” is becoming an endangered concept. @mikestiles @oraclesocial

• Adding AjaxOnly Filter in ASP.NET Web API

  - by imran_ku07

          Introduction:                     Currently, ASP.NET MVC 4, ASP.NET Web API and ASP.NET Single Page Application are the hottest topics in ASP.NET community. Specifically, lot of developers loving the inclusion of ASP.NET Web API in ASP.NET MVC. ASP.NET Web API makes it very simple to build HTTP RESTful services, which can be easily consumed from desktop/mobile browsers, silverlight/flash applications and many different types of clients. Client side Ajax may be a very important consumer for various service providers. Sometimes, some HTTP service providers may need some(or all) of thier services can only be accessed from Ajax. In this article, I will show you how to implement AjaxOnly filter in ASP.NET Web API application.         Description:                     First of all you need to create a new ASP.NET MVC 4(Web API) application. Then, create a new AjaxOnly.cs file and add the following lines in this file, public class AjaxOnlyAttribute : System.Web.Http.Filters.ActionFilterAttribute { public override void OnActionExecuting(System.Web.Http.Controllers.HttpActionContext actionContext) { var request = actionContext.Request; var headers = request.Headers; if (!headers.Contains("X-Requested-With") || headers.GetValues("X-Requested-With").FirstOrDefault() != "XMLHttpRequest") actionContext.Response = request.CreateResponse(HttpStatusCode.NotFound); } }                     This is an action filter which simply checks X-Requested-With header in request with value XMLHttpRequest. If X-Requested-With header is not presant in request or this header value is not XMLHttpRequest then the filter will return 404(NotFound) response to the client.                      Now just register this filter, [AjaxOnly] public string GET(string input)                     You can also register this filter globally, if your Web API application is only targeted for Ajax consumer.         Summary:                       ASP.NET WEB API provide a framework for building RESTful services. Sometimes, you may need your certain API services can only be accessed from Ajax. In this article, I showed you how to add AjaxOnly action filter in ASP.NET Web API. Hopefully you will enjoy this article too.

• Emoti-phrases

  - by Tony Davis

  Surely the next radical step in the development of User-interface design is for applications to react appropriately to the rising tide of bewilderment, frustration or antipathy of the users. When an application understands that rapport is lost, it should respond accordingly. When we, for example, become confused by an unforgiving interface, shouldn't there be a way of signalling our bewilderment and having the application respond appropriately? There is surprisingly little in the current interface standards that would help. If we're getting frustrated with an unresponsive application, perhaps we could let it know of our increasing irritation by means of an "I'm getting angry and exasperated" slider. Although, by 'responding appropriately', I don't include playing a "we are experiencing unusually heavy traffic: your application usage is important to us" message, accompanied by calming muzak. When confronted with a tide of wizards, 'are you sure?' messages, or page-after-page of tiresome and barely-relevant options, how one yearns for a handy 'JFDI' (Just Flaming Do It) button. One click and the application miraculously desists with its annoying questions and just gets on with the job, using the defaults, or whatever we selected last time. Much more satisfying, and more direct to most developers and DBAs, however, would be the facility to communicate to the application via a twitter-style input field, or via parameters to command-line applications ("I don't want a wide-ranging debate with you; just open the bl**dy PDF!" or, or "Don't forget which of us has the close button"). Although to avoid too much cultural-dependence, perhaps we should take the lead from emoticons, and use a set of standardized emoti-phrases such as 'sez you', 'huh?', 'Pshaw!', or 'meh', which could be used to vent a range of feelings in any given application, whether it be SQL Server stubbornly refusing to give us the result we are expecting, or when an online-survey is getting too personal. Or a 'Lingua Glaswegia' perhaps: 'Atsabelter' ("very good") 'Atspish' ("must try harder") 'AnThenYerArsFellAff ' ("I don't quite trust these results") 'BileYerHeid' or 'ShutYerGub' ("please stop these inane questions") There would, of course, have to be an ANSI standards body to define the phrases that were acceptable. Presumably, there would be a tussle amongst the different international standards organizations. Meanwhile Oracle, Microsoft and Apple would each release non-standard extensions. Time then, surely, to plant emoti-phrases on the lot of them and develop a user-driven consensus. Send us your suggestions! The best one will win an iPod nano! Cheers! Tony.

• How to Code Faster (Without Sacrificing Quality)

  - by ashes999

  I've been a professional coder for a several years. The comments about my code have generally been the same: writes great code, well-tested, but could be faster. So how do I become a faster coder, without sacrificing quality? For the sake of this question, I'm going to limit the scope to C#, since that's primarily what I code (for fun) -- or Java, which is similar enough in many ways that matter. Things that I'm already doing: Write the minimal solution that will get the job done Write a slew of automated tests (prevents regressions) Write (and use) reusable libraries for all kinds of things Use well-known technologies where they work well (eg. Hibernate) Use design patterns where they fit into place (eg. Singleton) These are all great, but I don't feel like my speed is increasing over time. I do care, because if I can do something to increase my productivity (even by 10%), that's 10% faster than my competitors. (Not that I have any.) Besides which, I've consistently gotten this feeback from my managers -- whether it was small-scale Flash development or enterprise Java/C++ development. Edit: There seem to be a lot of questions about what I mean by fast, and how I know I'm slow. Let me clarify with some more details. I worked in small and medium-sized teams (5-50 people) in various companies over various projects and various technologies (Flash, ASP.NET, Java, C++). The observation of my managers (which they told me directly) is that I'm "slow." Part of this is because a significant number of my peers sacrificed quality for speed; they wrote code that was buggy, hard to read, hard to maintain, and difficult to write automated tests for. My code generally is well-documented, readable, and testable. At Oracle, I would consistently solve bugs slower than other team-members. I know this, because I would get comments to that effect; this means that other (yes, more senior and experienced) developers could do my work in less time than it took me, at nearly the same quality (readability, maintainability, and testability). Why? What am I missing? How can I get better at this? My end goal is simple: if I can make product X in 40 hours today, and I can improve myself somehow so that I can create the same product at 20, 30, or even 38 hours tomorrow, that's what I want to know -- how do I get there? What process can I use to continually improve? I had thought it was about reusing code, but that's not enough, it seems.

• Programming doesn&rsquo;t have to be Magic

  - by Wes McClure

  In the show LOST, the Swan Station had a button that “had to be pushed” every 100 minutes to avoid disaster.  Several characters in the show took it upon themselves to have faith and religiously push the button, resetting the clock and averting the unknown “disaster”.  There are striking similarities in this story to the code we write every day.  Here are some common ones that I encounter: “I don’t know what it does but the application doesn’t work without it” “I added that code because I saw it in other similar places, I didn’t understand it, but thought it was necessary.” (for consistency, or to make things “work”) “An error message recommended it” “I copied that code” (and didn’t look at what it was doing) “It was suggested in a forum online and it fixed my problem so I left it” In all of these cases we haven’t done our due diligence to understand what the code we are writing is actually doing.  In the rush to get things done it seems like we’re willing to push any button (add any line of code) just to get our desired result and move on.  All of the above explanations are common things we encounter, and are valid ways to work through a problem we have, but when we find a solution to a task we are working on (whether a bug or a feature), we should take a moment to reflect on what we don’t understand.  Remove what isn’t necessary, comprehend and simplify what is.  Why is it detrimental to commit code we don’t understand? Perpetuates unnecessary code If you copy code that isn’t necessary, someone else is more likely to do so, especially peers Perpetuates tech debt Adding unnecessary code leads to extra code that must be understood, maintained and eventually cleaned up in longer lived projects Tech debt begets tech debt as other developers copy or use this code as guidelines in similar situations Increases maintenance How do we know the code is simplified if we don’t understand it? Perpetuates a lack of ownership Makes it seem ok to commit anything so long as it “gets the job done” Perpetuates the notion that programming is magic If we don’t take the time to understand every line of code we add, then we are contributing to the notion that it is simply enough to make the code work, regardless of how. TLDR Don’t commit code that you don’t understand, take the time to understand it, simplify it and then commit it!

• My thoughts on the future of the web with respect to flash, plugins, etc…

  - by joelvarty

  More than 10 years ago I was coding Java applets.  They were great at the time because I could reasonably expect them to run the same way in Netscape and Internet Explorer.  I could also reliably do asynchronous networking back to the server.  But then, Microsoft pulled their native Java runtime from Windows and Internet Explorer.  It got a lot harder to get applets running in people’s browsers. So I started writing ActiveX controls for IE and Java applets for Netscape. Then I switched to Flash, not for too long, but it was enough for me to see that it was a capable and curious implementation of animation, multimedia and script. I even wrote a few Silverlight controls, but then I stopped. I stepped back from all of the “richness” and “interactivity” and I thought about things like accessibility and SEO.  I wondered how my apps and sites might appear to the greater world.  I wondered how the developers I am working with, or who might be inheriting my code down the road, might interact with it. And I thought to myself, What the hell was I thinking? Those embedded controls are not what the web is about, and they run contrary to nearly all of the things that makes the web exciting and fosters innovation within and around.   Those plugins or controls, or whatever you want to refer to them as, are only stop-gaps that fill a hole in the basic HTML/Script/CSS specifications, and that’s all they should ever be used for.  Full stop.  Period.  For instance, I still make use of a nifty little flash control called SWFUpload because it lets me check file size before an upload starts.  I can do the same thing from a Silverlight control.  But rest assured, if I could do this from native javascript, I would in a second.  In fact, the only reason I chose SWFUpload over a ton of other alternatives is that it has a great javascript API so I can do (nearly) all of the UI in regular HTML.  And I ALWAYS provide a non-flash alternative for uploading, and for the rest of any website where the designer has insisted on some piece of creativity that requires flash (usually because the designer is also the flash developer, but that’s an aside…). The web is about openness, and about exposing that openness in such a way that it can be taken advantage of as a small part of a greater whole.  Sure we need security and authentication and ssl and all that stuff, but for me, its something more profound.  For me, the majority of what the web is, is about exposing something that delivers meaning.  What meaning can we derive from an <object> tag?   more later - joel

  Why business needs should shape IT architecture - McKinsey Quarterly - Business Technology - Organization "Too often, efforts to fix architecture issues remain rooted in a company’s IT practices, culture, and leadership. The reason, in part, is that the chief architect—the overall IT-architecture program leader—is frequently selected from within the technical ranks, bringing deep IT know-how but little direct experience or influence in leading a business-wide change program. A weak linkage to the business creates a void that limits the quality of the resulting IT architecture and the organization’s ability to enforce and sustain the benefits of implementation over time." -- Helge Buckow and Stéphane Rey (tags: architecture it technology enterprise mckinsey) Eric Maurice: April 2010 Critical Patch Update Released Eric Maurice offers the details on April 2010 Critical Patch Update (CPUApr2010), "the first one to include security fixes for Oracle Solaris" (tags: oracle otn database fusionmiddleware peoplesoft security) @shivmohan: Oracle – OAF – Oracle Application Framework – OA Framework "For all the PL/SQL and Oracle Forms developers out there, start planning your evolution.

• SQL SERVER – Select and Delete Duplicate Records – SQL in Sixty Seconds #036 – Video

  - by pinaldave

  Developers often face situations when they find their column have duplicate records and they want to delete it. A good developer will never delete any data without observing it and making sure that what is being deleted is the absolutely fine to delete. Before deleting duplicate data, one should select it and see if the data is really duplicate. In this video we are demonstrating two scripts – 1) selects duplicate records 2) deletes duplicate records. We are assuming that the table has a unique incremental id. Additionally, we are assuming that in the case of the duplicate records we would like to keep the latest record. If there is really a business need to keep unique records, one should consider to create a unique index on the column. Unique index will prevent users entering duplicate data into the table from the beginning. This should be the best solution. However, deleting duplicate data is also a very valid request. If user realizes that they need to keep only unique records in the column and if they are willing to create unique constraint, the very first requirement of creating a unique constraint is to delete the duplicate records. Let us see how to connect the values in Sixty Seconds: Here is the script which is used in the video. USE tempdb GO CREATE TABLE TestTable (ID INT, NameCol VARCHAR(100)) GO INSERT INTO TestTable (ID, NameCol) SELECT 1, 'First' UNION ALL SELECT 2, 'Second' UNION ALL SELECT 3, 'Second' UNION ALL SELECT 4, 'Second' UNION ALL SELECT 5, 'Second' UNION ALL SELECT 6, 'Third' GO -- Selecting Data SELECT * FROM TestTable GO -- Detecting Duplicate SELECT NameCol, COUNT(*) TotalCount FROM TestTable GROUP BY NameCol HAVING COUNT(*) > 1 ORDER BY COUNT(*) DESC GO -- Deleting Duplicate DELETE FROM TestTable WHERE ID NOT IN ( SELECT MAX(ID) FROM TestTable GROUP BY NameCol) GO -- Selecting Data SELECT * FROM TestTable GO DROP TABLE TestTable GO Related Tips in SQL in Sixty Seconds: SQL SERVER – Delete Duplicate Records – Rows SQL SERVER – Count Duplicate Records – Rows SQL SERVER – 2005 – 2008 – Delete Duplicate Rows Delete Duplicate Records – Rows – Readers Contribution Unique Nonclustered Index Creation with IGNORE_DUP_KEY = ON – A Transactional Behavior What would you like to see in the next SQL in Sixty Seconds video?

• SQL SERVER – Rename Columnname or Tablename – SQL in Sixty Seconds #032 – Video

  - by pinaldave

  We all make mistakes at some point of time and we all change our opinion. There are quite a lot of people in the world who have changed their name after they have grown up. Some corrected their parent’s mistake and some create new mistake. Well, databases are not protected from such incidents. There are many reasons why developers may want to change the name of the column or table after it was initially created. The goal of this video is not to dwell on the reasons but to learn how we can rename the column and table. Earlier I have written the article on this subject over here: SQL SERVER – How to Rename a Column Name or Table Name. I have revised the same article over here and created this video. There is one very important point to remember that by changing the column name or table name one creates the possibility of errors in the application the columns and tables are used. When any column or table name is changed, the developer should go through every place in the code base, ad-hoc queries, stored procedures, views and any other place where there are possibility of their usage and change them to the new name. If this is one followed up religiously there are quite a lot of changes that application will stop working due to this name change.  One has to remember that changing column name does not change the name of the indexes, constraints etc and they will continue to reference the old name. Though this will not stop the show but will create visual un-comfort as well confusion in many cases. Here is my question back to you – have you changed ever column name or table name in production database (after project going live)? If yes, what was the scenario and need of doing it. After all it is just a name. Let me know what you think of this video. Here is the updated script. USE tempdb GO CREATE TABLE TestTable (ID INT, OldName VARCHAR(20)) GO INSERT INTO TestTable VALUES (1, 'First') GO -- Check the Tabledata SELECT * FROM TestTable GO -- Rename the ColumnName sp_RENAME 'TestTable.OldName', 'NewName', 'Column' GO -- Check the Tabledata SELECT * FROM TestTable GO -- Rename the TableName sp_RENAME 'TestTable', 'NewTable' GO -- Check the Tabledata - Error SELECT * FROM TestTable GO -- Check the Tabledata - New SELECT * FROM NewTable GO -- Cleanup DROP TABLE NewTable GO Related Tips in SQL in Sixty Seconds: SQL SERVER – How to Rename a Column Name or Table Name What would you like to see in the next SQL in Sixty Seconds video?
