• Set App Windows to Always be on Top

  - by Asian Angel

  Sometimes you have a small app or other software that you want to keep topmost but how do you keep it on top without a lot of hassle? If this sounds like your situation then you might want to have a look at OnTop. Before For our example we had four individual apps open…any of the four could easily be on top at the moment. OnTop in Action The exe file for the app comes in a zip file. Simply unzip the file, place it in the Program Files Folder, create a shortcut and you are ready to go. Once you start OnTop you will see a new System Tray Icon…right click to access the Context Menu with a list of currently open apps. We decided to set Winamp to be always topmost first. Note: OnTop detected all three individual sections of our Winamp Player along with the individual monitors running in our Taskbar. Clicking on Paint.NET brought it forward over Firefox and Microsoft Word but Winamp was still sitting on top. Clicking on Microsoft Word next still did not affect Winamp’s topmost status. Nice. As soon as we switched the topmost status to Microsoft Word you can see that it immediately came to the front. One thing that we did note in our tests…the best method for switching topmost status is either to choose a different app or close the app that was topmost. Conclusion OnTop might be considered niche software but if you have an app window that you need to keep on top of other windows then you might want to give this small app a try.

• Oracle VM Deep Dives

  - by rickramsey

  "With IT staff now tasked to deliver on-demand services, datacenter virtualization requirements have gone beyond simple consolidation and cost reduction. Simply provisioning and delivering an operating environment falls short. IT organizations must rapidly deliver services, such as infrastructure-as-a-service (IaaS), platform-as-a-service (PaaS), and software-as-a-service (SaaS). Virtualization solutions need to be application-driven and enable:" "Easier deployment and management of business critical applications" "Rapid and automated provisioning of the entire application stack inside the virtual machine" "Integrated management of the complete stack including the VM and the applications running inside the VM." Application Driven Virtualization, an Oracle white paper That was published in August of 2011. The new release of Oracle VM Server delivers significant virtual networking performance improvements, among other things. If you're not sure how virtual networks work or how to use them, these two articles by Greg King and friends might help. Looking Under the Hood at Virtual Networking by Greg King Oracle VM Server for x86 lets you create logical networks out of physical Ethernet ports, bonded ports, VLAN segments, virtual MAC addresses (VNICs), and network channels. You can then assign channels (or "roles") to each logical network so that it handles the type of traffic you want it to. Greg King explains how you go about doing this, and how Oracle VM Server for x86 implements the network infrastructure you configured. He also describes how the VM interacts with paravirtualized guest operating systems, hardware virtualized operating systems, and VLANs. Finally, he provides an example that shows you how it all looks from the VM Manager view, the logical view, and the command line view of Oracle VM Server for x86. Fundamental Concepts of VLAN Networks by Greg King and Don Smerker Oracle VM Server for x86 supports a wide range of options in network design, varying in complexity from a single network to configurations that include network bonds, VLANS, bridges, and multiple networks connecting the Oracle VM servers and guests. You can create separate networks to isolate traffic, or you can configure a single network for multiple roles. Network design depends on many factors, including the number and type of network interfaces, reliability and performance goals, the number of Oracle VM servers and guests, and the anticipated workload. The Oracle VM Manager GUI presents four different ways to create an Oracle VM network: Bonds and ports VLANs Both bond/ports and VLANS A local network This article focuses the second option, designing a complex Oracle VM network infrastructure using only VLANs, and it steps through the concepts needed to create a robust network infrastructure for your Oracle VM servers and guests.

  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 Developer Data Modeler: On Notes, Comments, and Comments in RDBMS

  - by thatjeffsmith

  Ah the beautiful data model. They say a picture is worth a 1,000 words. And then we have our diagrams, how many words are they worth? Our friends from the Human Relations sample schema So our models describe how the data ‘works’ – whether that be at a logical-business level, or a technical-physical level. Developers like to say that their code is self-documenting. These would be very lazy or very bad (or both) developers. Models are the same way, you should document your models with comments and notes! I have 3 basic options: Comments Comments in RDBMS Notes So what’s the difference? Comments You’re describing the entity/table or attribute/column. This information will NOT be published in the database. It will only be available to the model, and hence, folks with access to the model. Table Comments (in the design only!) Comments in RDBMS You’re doing the same thing as above, but your words will be stored IN the data dictionary of the database. Oracle allows you to store comments on the table and column definitions. So your awesome documentation is going to be viewable to anyone with access to the database. RDBMS is an acronym for Relational Database Management System – of which Oracle is one of the first commercial examples If the DDL is produced and ran against a database, these comments WILL be stored in the data dictionary. Notes A place for you to add notes, maybe from a design meeting. Or maybe you’re using this as a to-do or requirements list. Basically it’s for anything that doesn’t literally describe the object at hand – that’s what the comments are for. I totally made these up. Now these are free text fields and you can put whatever you want here. Just make sure you put stuff here that’s worth reading. And it will live on…forever.

• DevExpress XAF, Behavior Driven Development (BDD), Domain Driven Development (DDD) and more&ndash;Introduction

  - by Patrick Liekhus

  OK.  I admit it.  I have been horrible at this blogging thing.  However, I have made a commitment to get better at it so here goes.  I have many crazy ideas when it comes to coding and how to make my processes better and now is the time to get them down on paper and get your feedback.  Now, these ideas might not be nearly as wild and crazy as Charlie Sheen, but at least they help me get through my coding assignments. So let’s start by laying out the vision and objectives of this exercise.  I have been trying to come up with the best set of tools, tips and practices so I can get a small team to be as productive as possible without burning out my resources.  My thoughts tend to lean towards the coding practices first as this is what I have been doing for years.  However, as one looks at the process as a whole, we need to remember to keep the users in mind.  If we don’t have a user to accept our application, do we really have an application in the first place? I have been using a commercial framework from DevExpress called eXpress Application Framework (XAF) with their eXpress Persistent Objects (XPO) behind the scenes for a few years.  We have had tremendous success with it and even implemented a code generation layer to save us some time.  Now we want more!!! My goals here are to create a technical stack that employs as many UI’s as possible, while being true to the layers and documenting the process along the way.  I will continue to have a series of these posts that will walk through each step as I work on it.  Right now here is what I have planned: Defining the solution SCRUM/Agile Story Planning Overview of Architectural Plan Feature Driven Development Domain Driven Development Persistence Layer with XPO Windows UI with XAF/XPO Web UI with XAF/XPO OData Services Layer Windows Mobile UI Android UI iPhone UI Blackberry UI Excel UI Outlook UI Lessons Learned I will explain the solution that I plan to implement in the next post.  Thanks again and let me know what you think.

• Technology Selection for a dynamic product

  - by Kuntal Shah

  We are building a product for Procurement Domain in JAVA. Following are the main technical requirements. Platform Independent Database Independent Browser Independent In functional requirements the product is very dynamic in nature. The main reason being the procurement process around the world is different from client to client. Briefly we need to have a dynamic workflow engine and a dynamic template engine. The workflow engine by which we can define any kind of workflows and the template engine allows us to define any kind of data structures and based on definition it can get the user input through workflow. We have been developing this product for almost 2 years. It has been a long time till we can get down with the dynamics of requirements. Till now we have developed a basic workflow and template engine and which is in use at one of the client. We have been using following technologies. GWT-Ext (Front End Framework) Hibernate (Database Layer) In between we have faced some issues with GWT-Ext (mainly browser compatibility) and database optimization due to sub classing in hibernate. For resolving GWT-Ext issue, which a dying community so we decided to move to SmartGWT. In SmartGWT we faced issues related to loading and now we are able to finalize that GWT 2.3 will be the way to go as the library is rich and performance is upto the mark. We are able to almost finalize GWT-Spring based front and middle layer. In hibernate, we found main issues with sub-classing due to that it was throwing astronomical queries and sometimes it would stop firing any queries for 5-10 seconds or may be around 30 seconds and then resume again. Few days back I came to one article related to ORM. I am a traditional .Net SQL developer and I have always worked with relational database. Reading through this article, I also found it relating to the issues I face. I am still not completely convinced of using hibernate and this article just supported my opinion. Following are the questions for which I am looking for an answer. Should we be going with Hibernate in case of dynamic database requirements and the load of the data will be heavy in future? How can we partition the data, how we can efficiently join the data, how we can optimize the queries? If the answer is no then how do we achieve database independence? Is our choice related to GWT and Spring proper or do we need to change that too? Should we use any other key value pair database if the data is dynamic in nature and it is very difficult to make it relational?

• Changing Focus on my Blog

  - by D'Arcy Lussier

  I try to limit these types of blog posts – the ones where I communicate some change as if I have a loyal subscriber base that will be somehow affected. Still, I think its of worth if for nothing else than to document for myself an acknowledgement that my career is evolving. For the last who knows how long, I’ve had this as my banner: It’s funny how technology focuses change over time. 3.5 – 4 years ago I was wanting to immerse myself in BizTalk. Then I shifted, focussing on Silverlight. I even started a short-lived Silverlight user group here in Winnipeg that had, IMO, one of the *best* UG logos ever (do a Google search for the old school Winnipeg Jets logo if you don’t catch the reference)… And even how I identified myself – as a Developer – isn’t really accurate anymore as I’ve shifted more into an architect/analyst role at Online Business Systems as well as getting much more involved in business development. So I’m switching the focus of this blog a bit. Nothing too great, but you’ll find my posts aren’t necessarily tied to a technology or platform. Instead I’ll be focussing on current passions and interests. Solution Architecture Before a line of code is written, a solution is envisioned. The process of performing solution analysis and architecture is an intriguing process that encompasses negotiation and interpersonal skills as much as technical knowledge. Business & Entrepreneurship Creating things, building things, and working with others – business is fascinating and exciting! Entrepreneurship, and intrapreneurship, are growing trends that I’ve been exploring over the last few years through my conference (www.prairiedevcon.com) and within Online. Microsoft At Online one of my roles is “Microsoft Practice Lead” and my entire career has been built around the Microsoft stack of technologies. That focus won’t change here on my blog, and there’s tonnes of exciting new products and technologies coming out of Redmond. Adoption This is a very personal subject that’s extremely close to my heart. I’m not talking about technology adoption, I’m talking about human adoption. Almost three years ago we adopted our first daughter, Sadie, and two years ago we adopted our second daughter, Skylar; an amazing new chapter in my life as I became a “parent”. Adoption is very much misunderstood, and many people have questions about it. Hopefully I can shed some light into our experiences and provide some guidance for those that are looking into it. So come along with me as I start chronicling the next phase of my career and life.

• Fair Comments

  - by Tony Davis

  To what extent is good code self-documenting? In one of the most entertaining sessions I saw at the recent PASS summit, Jeremiah Peschka (blog | twitter) got a laugh out of a sleepy post-lunch audience with the following remark: "Some developers say good code is self-documenting; I say, get off my team" I silently applauded the sentiment. It's not that all comments are useful, but that I mistrust the basic premise that "my code is so clearly written, it doesn't need any comments". I've read many pieces describing the road to self-documenting code, and my problem with most of them is that they feed the myth that comments in code are a sign of weakness. They aren't; in fact, used correctly I'd say they are essential. Regardless of how far intelligent naming can get you in describing what the code does, or how well any accompanying unit tests can explain to your fellow developers why it works that way, it's no excuse not to document fully the public interfaces to your code. Maybe I just mixed with the wrong crowd while learning my favorite language, but when I open a stored procedure I lose the will even to read it unless I see a big Phil Factor- or Jeff Moden-style header summarizing in plain English what the code does, how it fits in to the broader application, and a usage example. This public interface describes the high-level process and should explain the role of the code, clearly, for fellow developers, language non-experts, and even any non-technical stake holders in the project. When you step into the body of the code, the low-level details, then I agree that the rules are somewhat different; especially when code is subject to frequent refactoring that can quickly render comments redundant or misleading. At their worst, here, inline comments are sticking plaster to cover up the scars caused by poor naming conventions, failure in clarity when mapping a complex domain into code, or just by not entirely understanding the problem (/ this is the clever part). If you design and refactor your code carefully so that it is as simple as possible, your functions do one thing only, you avoid having two completely different algorithms in the same piece of code, and your functions, classes and variables are intelligently named, then, yes, the need for inline comments should be minimal. And yet, even given this, I'd still argue that many languages (T-SQL certainly being one) just don't lend themselves to readability when performing even moderately-complex tasks. If the algorithm is complex, I still like to see the occasional helpful comment. Please, therefore, be as liberal as you see fit in the detail of the comments you apply to this editorial, for like code it is bound to increase its' clarity and usefulness. Cheers, Tony.

• SpaceX’s Falcon 9 Launch Success And Reusable Rockets Test Partially Successful

  - by Gopinath

  Elon Musk’s SpaceX is closing on the dream of developing reusable rockets and likely in an year or two space launch rockets will be reusable just like flights, ships and cars. Today SpaceX launched an upgraded Falcon 9 rocket in to space to deliver satellites as well as to test their reusable rocket launching technology. All on board satellites were released on to the orbit and the first stage of rocket partially succeeded in returning back to Earth. This is a huge leap in space technology.   Couple of years ago reusable rockets were considered as impossible. NASA, Russian Space Agency, China, India or for that matter any other space agency never even attempted to build reusable rockets. But SpaceX’s revolutionary technology partially succeeded in doing the impossible! Elon Musk founded SpaceX with the goal of building reusable rockets and transporting humans to & from other planets like Mars. He says If one can figure out how to effectively reuse rockets just like airplanes, the cost of access to space will be reduced by as much as a factor of a hundred.  A fully reusable vehicle has never been done before. That really is the fundamental breakthrough needed to revolutionize access to space. Normally the first stage of a rocket falls back to Earth after burning out and is destroyed. But today SpaceX reignited first stage rocket after its separation and attempted to descend smoothly on to ocean’s surface. Though it did not fully succeed, the test was partially successful and SpaceX was able to recovers portions of first stage. Rocket booster relit twice (supersonic retro & landing), but spun up due to aero torque, so fuel centrifuged & we flamed out — Elon Musk (@elonmusk) September 29, 2013 With the partial success of recovering first stage, SpaceX gathered huge amount of information and experience it can use to improve Falcon 9 and build a fully reusable rocket. In post launch press conference Musk said if things go "super well", could refly a Falcon 9 1st stage by the end of next year. Falcon 9 Launch Video Next reusable first tests delayed by at least two launches SpaceX has a busy schedule for next several months with more than 50 missions scheduled using the new Falcon 9 rocket. Ten of those missions are to fly cargo to the International Space Shuttle for NASA.  SpaceX announced that they will not attempt to recover the first stage of Falcon 9 in next two missions. The next test will be conducted on  the fourth mission of Falcon 9 which is planned to carry cargo to Internation Space Station sometime next year. This will give time required for SpaceX to analyze the information gathered from today’s mission and improve first stage reentry systems.

• Who Are the BI Users in Your Neighborhood?

  - by Brian Dayton

  Forrester's Boris Evelson recently wrote a blog titled "Who are the BI Personas?" that I enjoyed for a number of reasons. It's a quick read, easy to grasp and (refreshingly) focuses on the users of technology VS the technology. As Evelson admits, he meant to keep the reference chart at a high-level because there are too many different permutations and additional sub-categories to make such a chart useful. For me, I wouldn't head into the technical permutations but more the contextual use of BI and the issues that users experience.  My thoughts brought up more questions than answers such as: Context: -          HOW: With the exception of the "Power User" persona--likely some sort of business or operations analyst? -          WHEN: Are they using the information to make real-time decisions on the front lines (a customer service manager or shipping/logistics VP) or are they using this information for cumulative analysis and business planning? Or both? -          WHERE: What areas of the business are more or less likely to rely on BI across an organization? Human Resources, Operations, Facilities, Finance--- and why are some more prone to use data-driven analysis than others? Issues: -          DELAYS & DRAG ON IT?: One of the persona characteristics Evelson calls out is a reliance on IT. Every persona except for the "Power User" has a heavy reliance on IT for support. What business issues or delays does that cause to users? What is the drag on IT resources who could potentially be creating instead of reporting? -          HOW MANY CLICKS: If BI is being used within the context of a transaction (sales manager looking for upsell opportunities as an example) is that person getting the information within the context of that action or transaction? Or are they minimizing screens, logging into another application or reporting tool, running queries, etc.?   Who are the BI Users in your neighborhood or line of business? Do Evelson's personas resonate--and do the tools that he calls out (he refers to it as "BI Style") resonate with what your personas have or need? Finally, I'm very interested if BI use is viewed as  a bolt-on...or an integrated part of your daily enterprise processes?

• Music before bells and whistles

  - by Tony Davis

  Why is it that Windows has so much difficulty in finding content on its file system? This is not an insurmountable technical problem; on my laptop, I have a database within which I can instantly find text or names within millions of records, within 300 milliseconds. I have a copy of Google Desktop that can find phrases within emails or documents, almost as quickly. It is an important, though mundane, part of an operating system to be able to find files. The first thing I notice within Windows is that the facility to find files or text within files is called 'search' rather than 'find'. Hmm. This doesn’t bode well. What’s this? It does a brute-force search for file names? Here we are in an age when we can breed mice that glow in the dark, and manufacture computers that fit in our shirt pockets, and we find an operating system that is still entirely innocent of managing and indexing content in hierarchical data. I can actually read the files of my PC into a database, mimic the directory/folder hierarchies and then find files in a flash; but when I do the same with Windows Vista, we are suddenly back in a 1960s time warp. Finding files based on their name is bad enough, but finding files based on the content that they contain is more or less asking for an opportunity to wait 20 minutes in order to see a "file not found" message. Sadly, with Windows 7, Microsoft seems to have fallen into the familiar trap of adding bells and whistles before finishing the song. It's certainly true that Microsoft has added new features and a certain polish to Windows Search 4.0, the latest incarnation. It works more like a web search and offers a new search syntax, called Advanced Query Syntax, which allows you to search on file author, file size, date ranges (e.g. date:=7/4/09still does not work reliably. I've experienced first-hand its stubborn refusal, despite a full index, to acknowledge the existence of a file I know exists, based on a search for a specific term within that file that I know is in there somewhere; a file that Google Desktop search, or old wingrep, finds in seconds. When users hark back to the halcyon days of Windows XP search, you know something is seriously amiss. Shouldn't applications get the functionality right before applying animated menus and Teletubby graphics, or is advancing age making me grumpy? I’d be pleased to hear your views, as always. Cheers, Tony.

• How can I troubleshoot flash player/hardware conflict?

  - by sparthikas

  OBJECTIVE: Have a web browser on my Ubuntu install that can play youtube and hulu videos. Also would like to understand problem so that I can fix it again if I change software. Workarounds welcome, technical understanding and solution preferable. SYMPTOMS: Flash does not run - cannot make the right-click menu appear, an empty box is where video should be, changes to black box when hovering over other links. The "The Adobe Flash plugin has crashed" message does not appear with its sad lego face. cannot activate proprietary graphics driver - causes system to reboot to a prompt. SOLUTIONS TRIED: Replaced OS (tried slackware 13.37, fedora 17, linuxmint 13 maya, gentoo, lubuntu, and even winXP. lubuntu confirmed to work, don't remember how much tweaking, if any, this required. Slack, fedora, mint, and gentoo all failed to run flash just like ubuntu) many reinstalls of flash player via different methods, including cleaning up old installs first, also tried gnash and lightspark. replaced graphics card (replaced HIS IceQ Radeon HD 4670 AGP with older GeForce 5700 LE no change in problem) flash does successfully work on winXP installation with Catalyst AGP hotfix driver applied, however I consider windows wholly unacceptable for web browsing due to lack of security. Lubuntu install also works, however I do not want to be tied down to just using Lubuntu on this computer. SYSINFO: Have latest versions of Ubuntu, Firefox, and Flash on fresh Ubuntu install. Using Gigabyte 7s748 motherboard with Athlon XP 2800+ and 3 GB of RAM with Radeon HD 4670 AGP card, also a Dell soundblaster live series sound card (due to malfunction of onboard sound on motherboard) Wired internet connection, Maxtor 6Y120L3 HDD, Sony DVD RW AW-Q170A, Dell M993s monitor. NOTES: I do not know if the graphics driver issue and the flash troubles are linked. Substitution of older graphics card having same flash troubles seems to suggest they aren't. My troubleshooting method is rather reductionist, consisting mainly of "replace things until you find out what was causing the error by process of elimination" only it seems that this must be a conflict which arises when software decides how to configure itself on my hardware. That is, I know the hardware can run Flash, and I know that on other systems the same software can too, but somehow the combination fails. Consequently I feel out of my depth. I will keep trying things off and on, but I have spent probably about 30 man-hours in the last 4 months working on this problem with no joy other than the lubuntu workaround. Any help will be appreciated, I will be checking back and posting updates. Any pertinent questions regarding me or my computer will be answered, outputs from config files can be accessed and posted (IDK which ones or what parts to post).

• Book review: Microsoft System Center Enterprise Suite Unleashed

  - by BuckWoody

  I know, I know – what’s a database guy doing reading a book on System Center? Well, I need it from time to time. System Center is actually a collection of about 7 different products that you can use to manage and monitor your software and hardware, from drive space through Microsoft Office, UNIX systems, and yes, SQL Server. It’s that last part I care about the most, and so I’ve dealt with Data Protection Manager and System Center Operations Manager (I call it SCOM) in SQL Server. But I wasn’t familiar with the rest of the suite nor was I as familiar as I needed to be with the “Essentials” release – a separate product that groups together the main features of System Center into a single offering for smaller organizations. These companies usually run with a smaller IT shop, so they sometimes opt for this product to help them monitor everything, including SQL Server. So I picked up “Microsoft System Center Enterprise Suite Unleashed” by Chris Amaris and a cast of others. I don’t normally like to get a technical book by multiple authors – I just find that most of the time it’s quite jarring to switch from author to author, but I think this group did pretty well here.  The first chapter on introducing System Center has helped me talk with others about what the product does, and which pieces fit well together with SQL Server. The writing is well done, and I didn’t find a jump from author to author as I went along. The information is sequential, meaning that they lead you from install to configuration and then use. It’s very much a concepts-and-how-to book, and a big one at that – over 950 pages of learning! It was a pretty quick read, though, since I skipped the installation parts and there are lots of screenshots. While I’m not sure you’d be an expert on the product when you finish reading this book, but I would say you’re more than halfway there. I would say it suits someone that learns through examples the best, since they have a lot of step-by-step examples I do recommend that you take a look if you have to interact with this product, or even if you are a smaller shop and you’re the primary IT resource. The last few chapters deal with System Center Essentials, and honestly it was the best part of the book for me. Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

• Is your test method self-validating ?

  - by mehfuzh

  Writing state of art unit tests that can validate your every part of the framework is challenging and interesting at the same time, its like becoming a samurai. One of the key concept in this is to keep our test synced all the time as underlying code changes and thus breaking them to the furthest unit as possible.  This also means, we should avoid  multiple conditions embedded in a single test. Let’s consider the following example of transfer funds. [Fact] public void ShouldAssertTranserFunds() {     var currencyService = Mock.Create<ICurrencyService>();     //// current rate     Mock.Arrange(() => currencyService.GetConversionRate("AUS", "CAD")).Returns(0.88f);       Account to = new Account { Currency = "AUS", Balance = 120 };     Account from = new Account { Currency = "CAD" };       AccountService accService = new AccountService(currencyService);       Assert.Throws<InvalidOperationException>(() => accService.TranferFunds(to, from, 200f));       accService.TranferFunds(to, from, 100f);       Assert.Equal(from.Balance, 88);     Assert.Equal(20, to.Balance); } At first look,  it seems ok but as you look more closely , it is actually doing two tasks in one test. At line# 10 it is trying to validate the exception for invalid fund transfer and finally it is asserting if the currency conversion is successfully made. Here, the name of the test itself is pretty vague. The first rule for writing unit test should always reflect to inner working of the target code, where just by looking at their names it is self explanatory. Having a obscure name for a test method not only increase the chances of cluttering the test code, but it also gives the opportunity to add multiple paths into it and eventually makes things messy as possible. I would rater have two test methods that explicitly describes its intent and are more self-validating. ShouldThrowExceptionForInvalidTransferOperation ShouldAssertTransferForExpectedConversionRate Having, this type of breakdown also helps us pin-point reported bugs easily rather wasting any time on debugging for something more general and can minimize confusion among team members. Finally, we should always make our test F.I.R.S.T ( Fast.Independent.Repeatable.Self-validating.Timely) [ Bob martin – Clean Code]. Only this will be enough to ensure, our test is as simple and clean as possible.   Hope that helps

• Development processes, the use of version control, and unit-testing

  - by ct01

  Preface I've worked at quite a few "flat" organizations in my time. Most of the version control policy/process has been "only commit after it's been tested". We were constantly committing at each place to "trunk" (cvs/svn). The same was true with unit-testing - it's always been a "we need to do this" mentality but it never really materializes in a substantive form b/c there is no institutional knowledge base to do it - no mentorship. Version Control The emphasis for version control management at one place was a very strict protocol for commit messages (format & content). The other places let employees just do "whatever". The branching, tagging, committing, rolling back, and merging aspect of things was always ill defined and almost never used. This sort of seems to leave the version control system in the position of being a fancy file-storage mechanism with a meta-data component that never really gets accessed/utilized. (The same was true for unit testing and committing code to the source tree) Unit tests It seems there's a prevailing "we must/should do this" mentality in most places I've worked. As a policy or standard operating procedure it never gets implemented because there seems to be a very ill-defined understanding about what that means, what is going to be tested, and how to do it. Summary It seems most places I've been to think version control and unit testing is "important" b/c the trendy trade journals say it is but, if there's very little mentorship to use these tools or any real business policies, then the full power of version control/unit testing is never really expressed. So grunts, like myself, never really have a complete understanding of the point beyond that "it's a good thing" and "we should do it". Question I was wondering if there are blogs, books, white-papers, or online journals about what one could call the business process or "standard operating procedures" or uses cases for version control and unit testing? I want to know more than the trade journals tell me and get serious about doing these things. PS: @Henrik Hansen had a great comment about the lack of definition for the question. I'm not interested in a specific unit-testing/versioning product or methodology (like, XP) - my interest is more about work-flow at the individual team/developer level than evangelism. This is more-or-less a by product of the management situation I've operated under more than a lack of reading software engineering books or magazines about development processes. A lot of what I've seen/read is more marketing oriented material than any specifically enumerated description of "well, this is how our shop operates".

• Using MVP, how to create a view from another view, linked with the same model object

  - by Dinaiz

  Background We use the Model-View-Presenter design pattern along with the abstract factory pattern and the "signal/slot" pattern in our application, to fullfill 2 main requirements Enhance testability (very lightweight GUI, every action can be simulated in unit tests) Make the "view" totally independant from the rest, so we can change the actual view implementation, without changing anything else In order to do so our code is divided in 4 layers : Core : which holds the model Presenter : which manages interactions between the view interfaces (see bellow) and the core View Interfaces : they define the signals and slots for a View, but not the implementation Views : the actual implementation of the views When the presenter creates or deals with views, it uses an abstract factory and only knows about the view interfaces. It does the signal/slot binding between views interfaces. It doesn't care about the actual implementation. In the "views" layer, we have a concrete factory which deals with implementations. The signal/slot mechanism is implemented using a custom framework built upon boost::function. Really, what we have is something like that : http://martinfowler.com/eaaDev/PassiveScreen.html Everything works fine. The problem However, there's a problem I don't know how to solve. Let's take for example a very simple drag and drop example. I have two ContainersViews (ContainerView1, ContainerView2). ContainerView1 has an ItemView1. I drag the ItemView1 from ContainerView1 to ContainerView2. ContainerView2 must create an ItemView2, of a different type, but which "points" to the same model object as ItemView1. So the ContainerView2 gets a callback called for the drop action with ItemView1 as a parameter. It calls ContainerPresenterB passing it ItemViewB In this case we are only dealing with views. In MVP-PV, views aren't supposed to know anything about the presenter nor the model, right ? How can I create the ItemView2 from the ItemView1, not knowing which model object is ItemView1 representing ? I thought about adding an "itemId" to every view, this id being the id of the core object the view represents. So in pseudo code, ContainerPresenter2 would do something like itemView2=abstractWidgetFactory.createItemView2(); this.add(itemView2,itemView1.getCoreObjectId()) I don't get too much into details. That just work. The problem I have here is that those itemIds are just like pointers. And pointers can be dangling. Imagine that by mistake, I delete itemView1, and this deletes coreObject1. The itemView2 will have a coreObjectId which represents an invalid coreObject. Isn't there a more elegant and "bulletproof" solution ? Even though I never did ObjectiveC or macOSX programming, I couldn't help but notice that our framework is very similar to Cocoa framework. How do they deal with this kind of problem ? Couldn't find more in-depth information about that on google. If someone could shed some light on this. I hope this question isn't too confusing ...

• How do I Integrate Production Database Hot Fixes into Shared Database Development model?

  - by TetonSig

  We are using SQL Source Control 3, SQL Compare, SQL Data Compare from RedGate, Mercurial repositories, TeamCity and a set of 4 environments including production. I am working on getting us to a dedicated environment per developer, but for at least the next 6 months we are stuck with a shared model. To summarize our current system, we have a DEV SQL server where developers first make changes/additions. They commit their changes through SQL Source Control to a local hgdev repository. When they execute an hg push to the main repository, TeamCity listens for that and then (among other things) pushes hgdev repository to hgrc. Another TeamCity process listens for that and does a pull from hgrc and deploys the latest to a QA SQL Server where regression and integration tests are run. When those are passed a push from hgrc to hgprod occurs. We do a compare of hgprod to our PREPROD SQL Server and generate deployment/rollback scripts for our production release. Separate from the above we have database Hot Fixes that will need to be applied in between releases. The process there is for our Operations team make changes on the PreProd database, and then after testing, to use SQL Source Control to commit their hot fix changes to hgprod from the PREPROD database, and then do a compare from hgprod to PRODUCTION, create deployment scripts and run them on PRODUCTION. If we were in a dedicated database per developer model, we could simply automatically push hgprod back to hgdev and merge in the hot fix change (through TeamCity monitoring for hgprod checkins) and then developers would pick it up and merge it to their local repository and database periodically. However, given that with a shared model the DEV database itself is the source of all changes, this won't work. Pushing hotfixes back to hgdev will show up in SQL Source Control as being different than DEV SQL Server and therefore we need to overwrite the reposistory with the "change" from the DEV SQL Server. My only workaround so far is to just have OPS assign a developer the hotfix ticket with a script attached and then we run their hotfixes against DEV ourselves to merge them back in. I'm not happy with that solution. Other than working faster to get to dedicated environment, are they other ways to keep this loop going automatically?

• Scrum and Team Consolidation

  - by John K. Hines

  I’m still working my way through one of the more painful team consolidations of my career.  One thing that’s made it hard was my assumption that the use of Agile methods and Scrum would make everything easy.  Take three teams, make all work visible, track it, and presto: An efficient, functioning software development team. What I’ve come to realize is that the primary benefit of Scrum is that Scrum brings teams closer to their customers.  Frequent meetings, short iterations, and phased deployments are all meant to keep the customer in the loop.  It’s true that as teams become proficient with Scrum they tend to become more efficient.  But I don’t think it’s true that Scrum automatically helps people work together. Instead, Scrum can point out when teams aren’t good at working together.   And it really illustrates when teams, especially teams in sustaining mode, are reacting to their customers instead of innovating with them.  At the moment we’ve inherited a huge backlog of tools, processes, and personalities.  It’s up to us to sort them all out.  Unfortunately, after 7 &frac12; months we’re still sorting. What I’d recommend for any blended team is to look at your current product lifecycles and work on a single lifecycle for all work.  If you can’t objectively come up with one process, that’s a good indication that the new team might not be a good fit for being a single unit (which happens all the time in bigger companies).  Go ahead & self-organize into sub-teams.  Then repeat the process. If you can come up with a single process, tackle each piece and standardize all of them.  Do this as soon as possible, as it can be uncomfortable.  Standardize your requirements gathering and tracking, your exploration and technical analysis, your project planning, development standards, validation and sustaining processes.  Standardize all of it.  Make this your top priority, get it out of the way, and get back to work. Lastly, managers of blended teams should realize what I’m suggesting is a disruptive process.  But you’ve just reorganized the team is already disrupted.   Don’t pull the bandage off slowly and force the team through a prolonged transition phase, lowering their productivity over the long term.  You can role model leadership to your team and drive a true consolidation.  Destroy roadblocks, reassure those on your team who are afraid of change, and push forward to create something efficient and beautiful.  Then use Scrum to reengage your customers in a way that they’ll love.
