• Creating sitemap for Googlebot - how to mark dynamic content / dynamic subpages?

  - by ojek

  I have a website that is an Internet forum. This forum has many categories, and a single category page that contains a lot of subpages with listed threads. This Internet forum is brand new, and about a week ago I filled it with a few hundred thousand threads. I then looked at my Google Webmasters Tools page to see any changes in indexing, but the index went up from 300 to about 1200, so that means it did not index my added threads (although it added something). The following is what my sitemap.xml contains, which I uploaded to their website. Of course there is a lot more code, this is just a snippet for a single category. In my real sitemap file I have all the categories listed as below: <url> <loc>http://mysite.com/Forums/Physics</loc> <changefreq>hourly</changefreq> </url> Now, I would expect Googlebot to go into mysite.com/Forums/Physics, and crawl through all the subpages with thread links, and then crawl inside of each thread and index its content. How can I achieve this? Also if this is unclear, I will add a real link to my website.

• "Siebel2FusionCRM Integration" solution by ec4u (D)

  - by Richard Lefebvre

  ec4u, a CRM System Integration leader based in Germany and Switzerland, and an historical Oracle/Siebel partner, offers a complete "Siebel2FusionCRM Integration" solution, based on tools methodology and services. ec4u Siebel2FusionCRM Integration solution's main objectives are: Integration between Siebel (on-premise) and Fusion CRM / Marketing (“in the cloud”) Accounts, Contacts and Addresses are maintained by Sales in Siebel CRM and synchronized in real-time into Fusion CRM / Marketing CDM Processing ensures clean data for marketing campaigns (validation and deduplication) Create E-Mail marketing campaigns and newsletters in Fusion The solution features: Upsert processes figure out what information needs to be updated, inserted or terminated (deleted). However, as Siebel is the data master, it is still a one-way synchronization. Handle deleted or nullified information by terminating them in Fusion CRM (set start and end date to define the validity period) Initial load and real-time synchronization use the same processes Invocations/Operations can be repeated due to no transactional support from Fusion web services Tagging sub entries in case of 1 to N mapping (Example: Telephone number is one simple field in Siebel but in Fusion you can have multiple telephone numbers in a sub table) E-Mail-Notification in case of any error (containing error message, instance number, detailed payload) Schematron Validation Interested?

• Book: DevOps for Developers

  - by Tori Wieldt

  We all know development and operations often act like silos, with "Just throw it over the wall!" being the battle cry. Many organizations unwittingly contribute to gaps between teams, with management by (competing) objectives; a clash of Agile practices vs. more conservative approaches; and teams using different sets of tools, such as Nginx, OpenEJB, and Windows on developers' machines and Apache, Glassfish, and Linux on production machines. At best, you've got sub-optimal collaboration, at worst, you've got the Hatfields and the McCoys.  The book DevOps for Developers helps bridge the gap between development and operations by aligning incentives and sharing approaches for processes and tools. It introduces DevOps as a modern way of bringing development and operations together. It also means to broaden the usage of Agile practices to operations to foster collaboration and streamline the entire software delivery process in a holistic way. Some single aspects of DevOps may not be new, for example, you may have used the tool Puppet for years already, but with a new mindset ("my job is not just to code, it's to serve the customer in the best way possible") and a complete set of recipes, you'll be well on your way to success. DevOps for Developers also by provides real-world use cases (e.g., how to use Kanban or how to release software). It provides a way to be successful in the real development/operations world. DevOps for Developers is written my Michael Hutterman, Java Champion, and founder of the Cologne Java User Group. "With DevOps for Developers, developers can learn to apply patterns to improve collaboration between development and operations as well as recipes for processes and tools to streamline the delivery process," Hutterman explains.

• What is the best way to track / record the current programming project you work on? [duplicate]

  - by user2424160

  This question already has an answer here: Methodology for Documenting Existing Code Base 6 answers When do you start documenting the code? 13 answers Where should a programmer explain the extended logic behind the code? 5 answers I have been in this problem for long time and I want to know how it's done in real / big companies project? Suppose I have the project to build a website. Now I divide the project into sub tasks and do it. But you know that suppose I have task1 in hand like export the page to pdf. Now I spend 3 days to do that , came across various problems, many Stack Overflow questions and in the end I solve it. Now 4 months after someone told me that there is some error in the code. Now by that I completely forgot about (60%) of how I did it and why I do this way. I document the code but I can't write the whole story of that in the code. Then I have to spend much time on code to find what was the problem so that I added this line etc. I want to know that is there any way that i can log steps in completing the project. So that I can see how I end up with code, what errors I got, what questions I asked on SO and etc. How people do it in real time? Which software to use? I know in our project management software called JIRA we have tasks but that does not cover what steps I took to solve that tasks. What is the best way so that when I look back at my 2 year old project, I know how I solve particular task?

• How to present a stable data model in a public API that allows internal data structures to be changed without breaking the public view of the data?

  - by Max Palmer

  I am in the process of developing an application that allows users to write C# scripts. These scripts allow users to call selected methods and to access and manipulate data in a document. This works well, however, in the development version, scripts access the document's (internal) data structures directly. This means that if we were to change the internal data model/structure, there is a good chance that someone's script will no longer compile. We obviously want to prevent this breaking change from happening, but still want to allow the user to write sensible C# code (whilst not restricting how we develop our internal data model as a result). We therefore need to decouple our scripting API and its data structures from our internal methods and data structures. We've a few ideas as to how we might allow the user to access a what is effectively a stable public version of the document's internal data*, but I wanted to throw the question out there to someone who might have some real experience of this problem. NB our internal document's data structure is quite complex and it could be quite difficult to wrap. We know we want to expose as little as possible in our public API, especially as once it's out there, it's out there for good. Can anyone help? How do scripting languages / APIs decouple their public API and data structures from their internal data structures? Is there no real alternative to having to write a complex interaction layer? If we need to do this, what's a good approach or pattern for wrapping complex data structures that include nested objects, including collections? I've looked at the API facade pattern, which looks like it's trying to address these kinds of issues, but are there alternatives? *One idea is to build a data facade that is kept stable across versions of our application. The facade exposes a set of facade data objects that are used in the script code. These maintain backwards compatibility and wrap access to our internal document's data model.

• What are the advantages of programming to under an OS as opposed to bare metal executive?

  - by gby

  Assume you are presented with an embedded system application to program, in C, on a multi-core environment (think a Cavium or Tilera) and need to choose between two environments: Code the application under Linux in SMP mode or code the application under a thin bare metal executive (something like a very minimal RTOS), perhaps with a single core running UP Linux that can serve control tasks. For the purpose of this question, assume that both environment provide the same level of performance guarantees in any measurable aspects of run time performance, including number of meaningful action per second, jitter, latency, real time considerations - the works. (and yes, I realize this is by far not a trivial assumption at all, bare with me). How would you justify going with a Linux SMP based solution rather then a bare metal thin executive solution? The question may seems silly. It certainly seems obvious to me - but I have to convince someone that does not think the same. Could you help make a list of arguments in favor of choosing a real SMP aware OS (Linux) vs. a bare metal executive assuming performance guarantees are NOT an issue? Many thanks

• Improved Customer Experience, but at what Cost?

  - by Tony Berk

  We can all probably agree that improving your customers' experience is a good thing. But a key question many people are asking is will it help your organization and, in particular, what are the financial benefits?That's a good question, especially when companies ARE experiencing phenomenal return on investment (ROI). Of course, there are many factors that impact ROI or other measures of success, but we'd like to share some success stories as examples of customer experience in action and delivering positive results. If you would like to learn more about the economics of customer experience, see Brian Curran's presentation at the Oracle Customer Experience Summit last month. In this series of blog posts, we'll share actual customer stories. Today's example is Dell, which uses Oracle Real-Time Decisions (RTD) and Siebel CRM as part of their customer experience portfolio to better understand their customers' needs and wants and provide consistent interactions. Regular readers of this blog are probably familiar with Siebel, but RTD may be new to many of you. RTD is a complete decision management solution that delivers real-time decisions and recommendations and automatically renders decisions within a business process to create tailored messaging for every customer interaction.What does that mean? In the video below, Dell describes how customer experience is important not just for one interaction channel, but across all "vehicles." RTD is helping Dell understand customer behavior and communicate with the customer in a more relevant manner, across all communication  or interaction channels including sales and service call centers, email marketing and online. Dell continues to expand use of RTD because the benefits are showing up in sales, service and marketing results including 19% increase in close rates, faster issue resolution and 40% improvement in revenue per click in email marketing.

• Metaphor for task synchronization [closed]

  - by nkint

  I'm looking for a metaphor. A friend of mine taught me to use metaphors from nature, everyday life, math, and use them to design my projects. They can help in creating a better design or better understanding or the problem, and they are cool. Now I'm working on a project with hardware and micro-controllers in C. For convenience, I have decided to use multiple micro-controllers as co-processor units for real-time (the slaves) and a master. This has saved me a lot of headache: I can code the main logic in the master without paying too much attention to super optimizing everything; I don't care if I need some blocking-call; I don't worry about serial communication with the computer. I just send messages to the slaves and they are super fast super in real time. I like my design and it seems to work well. So here are the important concepts that I'm trying capture in the metaphor: hierarchy of processing Not using one big brain but rather several small, distributed brain units using distributed power or resources I'm looking for a good metaphor for this concept of having one unit synchronize the work of all the others. Preferably, the metaphor would come from nature, biology, or zoology.

• The Developers Conference 2012: Presentation about CEP & BAM

  - by Ricardo Ferreira

  This year I had the pleasure again of being one of the speakers in the TDC ("The Developers Conference") event. I have spoken in this event for three years from now. This year, the main theme of the SOA track was EDA ("Event-Driven Architecture") and I decided to delivery a comprehensive presentation about one of my preferred personal subjects: Real-time using Complex Event Processing. The theme of the presentation was "Business Intelligence in Real-time using CEP & BAM" and I would like to share here the presentation that I have done. The material is in Portuguese since was an Brazilian event that happened in São Paulo. Once my presentation has a lot of videos, I decided to share the material as a Youtube video, so you can pause, rewind and play again how many times you want it. I strongly recommend you that before starting watching the video, you change the video quality settings to 1080p in High Definition.

• Kids and programming: ScratchKara

  - by Mike Pagel

  Ever now and then I kept wondering how to share with my kids the excitement of creating something with your computer. Of course, today this is a bit more difficult, as they have seen 3D animation games and well-edited websites. I guess that's why they weren't all that hyped when I found my first computer model at our local recycling facilities (an 8-bit Laser VZ-200 with rubber keys). When I finally got it up and running with an old analog TV set they finally asked whether we could play soccer on it. Needless to say that my showing them how it remembers some BASIC commands and lists and executes them did not make any impression. So the question is for real: How do you get today's kids excited about programming? And just recently I looked again for environments that allow even young kids (mine are 7 and 9 years old now) to do something and have fun. Obviously any real, text-oriented programming language wouldn't work well. To cut it short: Something really nice was built by University of Oldenburg: ScratchKara. It is the perfect mixture of Kara, a simulation of a little ladybug and Scratch, an authoring environment from MIT. ScratchKara allows kids to initially simply explore how the bug moves and turns by pressing the action buttons, then move towards sequencing commands through drag & drop, and eventually end up building algorithms with procedures and functions. Even through it is built for kids and beginners, the environment comes with debugging and refactoring, which I found more than amazing. My kids love it and I have to admit I keep thinking about how to solve a bit more advanced problems with this language, which does not allow you to store any state information (other than your call stack). Yes, I am hooked, too... Once the language is understood you can then move to one of the original Kara versions, where you can define the bug's behavior through finite statemachines, Turing tables, Java and other textual languages. And from there, anything is possible.

• Is these company terms good for a programmer or should I move?

  - by o_O

  Here are some of the terms and conditions set forward by my employer. Does these make sense for a job like programming? No freelancing in any way even in your free time outside company work hours (may be okay. May be they wanted their employees to be fully concentrating on their full time job. Also they don't want their employees to do similar work for a competing client. Completely rational in that sense). - So sort of agreed. Any thing you develop like ideas, design, code etc while I'm employed there, makes them the owner of that. Seriously? Don't you think that its bad (for me)? If I'm to develop something in my free time (by cutting down sleep and hard working), outside the company time and resource, is that claim rational? I heard that Steve Wozniak had such a contract while he was working at HP. But that sort of hardware design and also those companies pay well, when compared to the peanuts I get. No other kind of works allowed. Means no open source stuffs. Fully dedicated to being a puppet for the employer, though the working environment is sort of okay. According to my assessment this place would score a 10/12 in Joel's test. So are these terms okay especially considering the fact that I'm underpaid with peanuts?

• Linux distro for software development support?

  - by Xie Jilei

  I've spent too much time on setup & maintain a development server, which contains following tools: Common services like SSH, BIND, rsync, etc. Subversion, Git. Apache server, which runs CGit, Trac, Webmin, phpmyadmin, phppgadmin, etc. Jetty, which runs Archiva and Hudson. Bugzilla. PostgresSQL server, MySQL server. I've created a lot of Debian packages, like my-trac-utils, my-bugzilla-utils, my-bind9-utils, my-mysql-utils, etc. to make my life more convenient. However, I still feel I need a lot more utils. And I've spent a lot of time to maintain these packages, too. I think there maybe many developers doing the same things. As tools like subversion, git, trac are so common today. It's not to hard to install and configure each of them, but it took a long time to install them all. And it's time consuming to maintain them. Like backup the data, plot the usage graph and generate web reports. (gitstat for example) So, I'd like to hear if there exist any pre-configured distro for Development Server purpose, i.e., something like BackTrack for hackers?

• My parked domain was de-indexed by Google - what to do?

  - by Programmer Joe

  I have a question about how to handle my domain. In a nutshell, I bought a domain last year from Go Daddy. My intention was to launch a real site with this domain and I have spent the last year working on my site. For the last year, I have been using the default Go Daddy page display for an up and coming site. When I first bought this site, it was indexed by Google - you could search for "alphabanter" and my site would show up on the search result page for Google. Several months ago, it seemed Google de-indexed my domain and if you type "alphabanter," my domain no longer shows up on the list of search results. However, if you search for "www.alphabanter.com", that's the only way it shows up in the search results for Google. Anyways, I am about to launch my site for real. However, I don't quite know if I can get my site back into Google's index. I have a few questions: 1) Was my domain permanently penalized by Google and removed from their index just because it was a parked domain? I don't believe I have done anything abusive other than using the Go Daddy default page for almost a year because my site was not ready. 2) Should I just launch my site, put a few backlinks to my site, and hope that Google indexes my site again? 3) Should I submit my site to Google at Google submit your content I assume getting Google to reconsider my site is the last option if none of the above works.

• How do I disable all lid close processes?

  - by Mat

  I want to be able to close my laptop without Ubuntu registering it. I've been looking everywhere and I've found plenty of people with the same problem but no real solutions. Obviously I have set the lid close setting to 'do nothing' for both AC and battery, but when I close the lid it still blanks the screen, disconnects from external monitors, and brings up the lock screen when I reopen it. Some people have suggested disabling the lock screen, but this doesn't stop the screen blanking and external displays disconnecting, and I don't want to disable the lock anyway, as I still want it when I tell Ubuntu to lock or sleep or whatever else. Others have suggested it's something to do with ACPI support, but I have tried changing some ACPI scripts, and even removed them completely (e.g. /etc/acpi/lid.sh and /etc/acpi/events/lidbtn) and it makes no difference. There must be a bit of code somewhere that can just be removed or commented out or altered to prevent any lid close actions - does anyone know where? I know this has been asked before, but I'm getting really frustrated with this problem. I'm disappointed to say that I'm actually using Windows 7 more often just because it's quite happy to completely ignore the closed lid. So I just wanted to check, are we any closer to a real solution for this problem?

• What is a user-friendly solution to editing email templates with replacement variables?

  - by Daniel Magliola

  I'm working on a system where we rely a lot of "admins / managers" emailing users from the database. One of the key features is being able to email several people at the same time, with specific information relevant to each of them. Another key feature is to be able to hand-craft emails, because it tends to be be necessary to slightly modify them each time, but having a basic template saves a lot of time. For this, we have the typical "templates" solution, where we have a template that looks kind of like this: Hello {{recipient.full_name}}, Your application to {{activity.title}} has been accepted. You have requested to participate on dates {{application.dates}}, in role {{application.role}} Blah blah blah The problem we are having is obviously that (as we expected), managers don't get the whole "variables" idea, and they do things like overwriting them, which doesn't let them email more than one person at a time, assuming those are not going to get replaced and that the system is broken, or even inexplicable things like "Hello {{John}}". The big problem is that this isn't relegated, as usual, to an "admin" section where only a few power users have access to editing the templates that are automatically send out, and they're expected to know what they are doing. Every user of the system gets exposed to this problem. The obvious solution would be to replace the variables before showing this template for the user to edit, but that doesn't work when emailing several people. This seems like a reasonably common problem, and we are kind of hoping that someone has already solved it. Have you seen anywhere/created/can think of good solutions to this problem?

• Effortlessly resize images in Orchard 1.7

  - by Bertrand Le Roy

  I’ve written several times about image resizing in .NET, but never in the context of Orchard. With the imminent release of Orchard 1.7, it’s time to correct this. The new version comes with an extensible media pipeline that enables you to define complex image processing workflows that can automatically resize, change formats or apply watermarks. This is not the subject of this post however. What I want to show here is one of the underlying APIs that enable that feature, and that comes in the form of a new shape. Once you have enabled the media processing feature, a new ResizeMediaUrl shape becomes available from your views. All you have to do is feed it a virtual path and size (and, if you need to override defaults, a few other optional parameters), and it will do all the work for you of creating a unique URL for the resized image, and write that image to disk the first time the shape is rendered: <img src="@Display.ResizeMediaUrl(Path: img, Width: 59)"/> Notice how I only specified a maximum width. The height could of course be specified, but in this case will be automatically determined so that the aspect ratio is preserved. The second time the shape is rendered, the shape will notice that the resized file already exists on disk, and it will serve that directly, so caching is handled automatically and the image can be served almost as fast as the original static one, because it is also a static image. Only the URL generation and checking for the file existence takes time. Here is what the generated thumbnails look like on disk: In the case of those product images, the product page will download 12kB worth of images instead of 1.87MB. The full size images will only be downloaded as needed, if the user clicks on one of the thumbnails to get the full-scale. This is an extremely useful tool to use in your themes to easily render images of the exact right size and thus limit your bandwidth consumption. Mobile users will thank you for that.

• How do I get my graphic card to work properly?

  - by Lucas

  I been having some problems with my graphic card for a time now. But I had enough when I did'nt get Oil Rush to work on my HP Pavilion g6. The system has suggested hardware drivers for me, but the first time I installed them they pretty much fucked up the graphics. After some time I managed to get the computere to work properly (I thought) again. When the game did'nt work I tried to the hardware drivers for the graphic card anyway. First of all there was to possible choices insted of one, as the last time I installed the drivers (when it did'nt work out so good). The choices are: ATI/AMDs proprietary video drivers FGLRX (update for edition) and Proprietary FGLRX-video drivers for ATI/AMD I realized the drivers probebly are pretty much the same, so I tried the first one. But this did'nt work. Instead I was asked to "Look in to /usr/var/log/jockey.log". This did'nt helped me much. Instead I choiced the other one, wich was installed and after reboot there where some changes. First of all there was a lot more details for Unity that was'nt there before and some shortkeys are now working that did'nt before (like Ctrl + T and the Prt Sc-button). But overall everything doesn't work as it used to. Like when you browse between the workspaces it doesn't look the same. To get to the point: it doesn't work well right now even if I got some things better and now will not Oil Rush (as I mentioned in the beginning) even start. SO! Can someone give me any advice with this? I'm stuck. Can't manage to see whats wrong right now. Any help? My graphic card is AMD Radeon HD 6470M.

• What benefits can I get upgrading my ASP.NET (Webform) + DAL(EF) + Repository + BLL structure to MVC?

  - by Etienne

  I'm in the process of defining an approach that may best fit our needs for a big web application development. For now, I'm thinking going with an ASP.NET Architecture with a DAL using Entity Framework, a Repository concept to not access DAL directly from BLL and a BLL that call the repository and make every manipulations necessary to prepare data to push in a presentation layer (.aspx files). I don't plan to use ASP.Net controls and prefer to keep things simple and lightweight using plain html, jQuery UI controls and do most of the server calls with jQuery Ajax. Sometimes, when needed, I plan to use handlers (.ashx) to call BLL methods that will return JSON or HTML to client for dynamic stuff. My solution also has a test project that Mock the Repository with in-memory data to not repose on database for testing BLL methods... It may be usefull to add that we will build a big application over this architecture with hundreds of tables and store procedures with a lot of reading and writing to database. My question is, having this architecture in mind, Is there any evident advantages that I can obtain by using an MVC3 project instead of the described architecture base on Webform? Do you see any problem in this architecture that may cause us problem during the next steps of development? I know the MVC pattern for using it in others projects with Django... but the Microsoft MVC implementation look so much more complex and verbose than Django MVC and it's why I'm hesitating (or waiting for a little push?) right now before jumping into it... We are in a real project with deadlines and don't want to slow the development process without any real benefits.

• Calling COM from Intel Fortran?

  - by user57460

  I'm trying to get COM working from my Fortran application. I do a "COMINITIALIZE" followed by a "COMCreateObjectByProgID". Both of these appear to be successful and return a status of zero. However, when I try to use the COM object, I get "Unhandled exception at 0x00000000 in FortranProg01.exe: 0xC0000005: Access violation." I realize that this error can mean almost anything, but has anyone got some suggestions of common problems with COM that produce this problem? Here are some more details. My program code: program FortranProg01 use myolepg implicit none integer*4 comInitStatus integer:: comCreateStatus INTEGER(INT_PTR_KIND()) $OBJECT INTEGER(4) funcResult REAL(8) pkgVersion call COMINITIALIZE(comInitStatus) print *, comInitStatus call COMCreateObjectByProgID('MyOlePg.MyOlePkg', $OBJECT, comCreateStatus) print *, comCreateStatus funcResult = IMyOlePkg_GetPackageVersion($OBJECT, pkgVersion) print *, funcResult call COMUNINITIALIZE() end program FortranProg01 The wizard-generated interface code: INTERFACE !property PackageVersion INTEGER(4) FUNCTION IMyOlePkg_GetPackageVersion($OBJECT, pVal) INTEGER(INT_PTR_KIND()), INTENT(IN) :: $OBJECT ! Object Pointer !DEC$ ATTRIBUTES VALUE :: $OBJECT REAL(8), INTENT(OUT) :: pVal !DEC$ ATTRIBUTES REFERENCE :: pVal !DEC$ ATTRIBUTES STDCALL :: IMyOlePkg_GetPackageVersion END FUNCTION IMyOlePkg_GetPackageVersion END INTERFACE Any help would be much appreciated! Thanks! Brad.

• Generic Repositories with DI & Data Intensive Controllers

  - by James

  Usually, I consider a large number of parameters as an alarm bell that there may be a design problem somewhere. I am using a Generic Repository for an ASP.NET application and have a Controller with a growing number of parameters. public class GenericRepository<T> : IRepository<T> where T : class { protected DbContext Context { get; set; } protected DbSet<T> DbSet { get; set; } public GenericRepository(DbContext context) { Context = context; DbSet = context.Set<T>(); } ...//methods excluded to keep the question readable } I am using a DI container to pass in the DbContext to the generic repository. So far, this has met my needs and there are no other concrete implmentations of IRepository<T>. However, I had to create a dashboard which uses data from many Entities. There was also a form containing a couple of dropdown lists. Now using the generic repository this makes the parameter requirments grow quickly. The Controller will end up being something like public HomeController(IRepository<EntityOne> entityOneRepository, IRepository<EntityTwo> entityTwoRepository, IRepository<EntityThree> entityThreeRepository, IRepository<EntityFour> entityFourRepository, ILogError logError, ICurrentUser currentUser) { } It has about 6 IRepositories plus a few others to include the required data and the dropdown list options. In my mind this is too many parameters. From a performance point of view, there is only 1 DBContext per request and the DI container will serve the same DbContext to all of the Repositories. From a code standards/readability point of view it's ugly. Is there a better way to handle this situation? Its a real world project with real world time constraints so I will not dwell on it too long, but from a learning perspective it would be good to see how such situations are handled by others.

• Rule of thumb for cost vs. savings for code re-use

  - by Styler

  Is it a good rule of thumb to always write code for the intent of re-using it somewhere down the road? Or, depending on the size of the component you are writing, is it better practice to design it for re-use when it makes sense with regards to time spent on it. What is a good rule of thumb for spending extra time on analysis and design on project components that have "some probability" of being needed later down the road for other things that may or may need this part. For example, if I have the need for project X to do things A, and B. A definitely needs to be written for re-use because it just makes sense to do so. B is very project specific at the moment, and I can hack it all together in a couple days to finish the project on time and give everyone kudos for being a great team, etc. Or if we say, lets spend a whole friggin' 2 weeks figuring out what project Y/Z might need this thing for and spend a load of extra time on on part B because someday we might need to use it on project Y/Z (where the savings will be realized). I'd imagine a perfect world situation would be a nicely crafted combination of project specific vs. re-use architected components given the project. However some code shops might feel it would be a great idea to write everything for the intention of using it at some point down the road.
