  • What is an effective git process for managing our central code library?

    - by Mathew Byrne
    Quick background: we're a small web agency (3-6 developers at any one time) developing small to medium sized Symfony 1.4 sites. We've used git for a year now, but most of our developers have preferred Subversion and aren't used to a distributed model. For the past 6 months we've put a lot of development time into a central Symfony plugin that powers our custom CMS. This plugin includes a number of features, helpers, base classes etc. that we use to build custom functionality. This plugin is stored in git, but branches wildly as the plugin is used in various products and is pulled from/pushed to constantly. The repository is usually used as a submodule within a major project. The problems we're starting to see now are a large number of Merge conflicts and backwards incompatible changes brought into the repository by developers adding custom functionality in the context of their own project. I've read Vincent Driessen's excellent git branching model and successfully used it for projects in the past, but it doesn't seem to quite apply well to our particular situation; we have a number of projects concurrently using the same core plugin while developing new features for it. What we need is a strategy that provides the following: A methodology for developing major features within the code repository. A way of migrating those features into other projects. A way of versioning the core repository, and of tracking which version each major project uses. A plan for migrating bug fixes back to older versions. A cleaner history that's easier to see where changes have come from. Any suggestions or discussion would be greatly appreciated.

  • Understanding branching strategy/workflow correctly

    - by burnersk
    I'm using svn without branches (trunk-only) for a very long time at my workplace. I had discovered most or all of the issues related to projects which do not have any branching strategy. Unlikely this is not going to change at my workplace but for my private projects. For my private projects which most includes coworkers and working together at the same time on different features I like to have an robust branching strategy with supports long-term releases powered by git. I find out that the Atlassian Toolchain (JIRA, Stash and Bamboo) helped me most and it also recommending me an branching strategy which I like to verify for the team needs. The branching strategy was taken directly from Atlassian Stash recommendation with a small modification to the hotfix branch tree. All hotfixes should also merged into mainline. The branching strategy in words mainline (also known as master with git or trunk with svn) contains the "state of the art" developing release. Everything here was successfully checked with various automated tests (through Bamboo) and looks like everything is working. It is not proven as working because of possible missing tests. It is ready to use but not recommended for production. feature covers all new features which are not completely finished. Once a feature is finished it will be merged into mainline. Sample branch: feature/ISSUE-2-A-nice-Feature bugfix fixes non-critical bugs which can wait for the next normal release. Sample branch: bugfix/ISSUE-1-Some-typos production owns the latest release. hotfix fixes critical bugs which have to be release urgent to mainline, production and all affected long-term *release*es. Sample branch: hotfix/ISSUE-3-Check-your-math release is for long-term maintenance. Sample branches: release/1.0, release/1.1 release/1.0-rc1 I am not an expert so please provide me feedback. Which problems might appear? Which parts are missing or slowing down the productivity?

  • Google Loon–A network of balloons to provide internet to everyone

    - by Gopinath
    Google once just a super powerful search engine provider and now they are venturing in to a lot of interesting non software projects like self driving cars, glasses that beam information right on to your eye balls, high speed internet services @ 1 Giga bytes per second. A recent addition to this innovative list is Google Loon – a network of flying balloons that provide internet access to remote parts of the world where it is not feasible for many governments/corporate to provider internet services. Google says there are several billions of people around the world who don’t have access to internet and Google Loon aim is to provide internet facilities to all these people. A pilot project is started couple of days ago by launching 30 balloons into stratosphere from New Zealand. These balloons fly 20 Kilometers above earth(much higher than where aero planes fly) and they beam internet to homes having Loon receiver wirelessly. Checkout the embedded introductory video on Google Loon What is in it for Google? Why is Google getting into these type of projects and what is in it for them? Google is the gateway to web and majority of people find information on web using Google Services/Software. So providing internet facilities to more people means, more people using Google services and it in turn contributes to their revenue growth. Google is not a charity, they do all these projects to earn money just like every other corporate. The best part is while earning money they are touching lives of billions of people in a positive way. Just imagine everyone in the world connected and have ability to take informed decisions irrespective of whether they live in developed countries or underprivileged parts of the world! Wow that will be a beautiful day.

  • Our winners- and some BBQ for everyone

    - by Steve Tunstall
    Congrats to our two winners for the first two comments on my last entry. Steve from Australia and John Lemon. Steve won since he was the first person over the International Date Line to see the post I made so late after a workday on Friday. So not only does he get to live in a country with the 2nd most beautiful women in the world, but now he gets some cool Oracle Swag, too. (Yes, I live on the beach in southern California, so you can guess where 1st place is for that other contest…Now if Steve happens to live in Manly, we may actually have a tie going…) OK, ok, for everyone else, you can be winners, too. How you ask? I will make you the envy of every guy and gal in your neighborhood or campsite. What follows is the way to smoke the best ribs you or anyone you know have ever tasted. Follow my instructions and give it a try. People at your party/cookout/campsite will tell you that they’re the best ribs they’ve ever had, and I will let you take all the credit. Yes, I fully realize this post is going to be longer than any post I’ve done yet. But let’s get serious here. Smoking meat is much more important, agreed? J In all honesty, this is a repeat of another blog I did, so I’m just copying and pasting. Step 1. Get some ribs. I actually really like Costco’s pack. They have both St. Louis and Baby Back. (They are the same ribs, but cut in half down the sides. St. Louis style is the ‘front’ of the ribs closest to the stomach, and ‘Baby back’ is the part of the ribs where is connects to the backbone). I like them both, so here you see I got one pack of each. About 4 racks to a pack. So these two packs for $25 each will feed about 16-20 of my guests. So around 3 bucks a person is a pretty good deal for the best ribs you’ll ever have. Step 2. Prep the ribs the night before you’re going to smoke. You need to trim them to fit your smoker racks, and also take off the membrane and add your rub. Then cover and set in fridge overnight. Here’s how to take off the membrane, which will not break down with heat and smoke like the rest of the meat, so must be removed. Use a butter knife to work in a ways between the membrane and the white bone. Just enough to make room for your finger. Try really hard not to poke through the membrane, you want to keep it whole. See how my gloved fingers can now start to lift up and pull off the membrane? This is what you are trying to do. It’s awesome when the whole thing can come off at once. This one is going great, maybe the best one I’ve ever done. Sometime, it falls apart and doesn't come off in one nice piece. I hate when that happens. Now, add your rub and pat it down once into the meat with your other hand. My rub is not secret. I got it from my mentor, a BBQ competitive chef who is currently ranked #1 in California and #3 in the nation on the BBQ circuit. He does full-day classes in southern California if anyone is interested in taking his class. Go to www.slapyodaddybbq.com to check him out. I tweaked his run recipe a tad and made my own. It’s one part Lawry’s, one part sugar, one part Montreal Steak Seasoning, one part garlic powder, one-half part red chili powder, one-half part paprika, and then 1/20th part cayenne. You can adjust that last ingredient, or leave it out. Real cheap stuff you can get at Costco. This lets you make enough rub to last about a year or two. Don’t make it all at once, make a shaker’s worth and use it up before you make more. Place it all in a bowl, mix well, and then add to a shaker like you see here. You can get a shaker with medium sized holes on it at any restaurant supply store or Smart & Final. The kind you see at pizza places for their red pepper flakes works best. Now cover and place in fridge overnight. Step 3. The next day. Ok, I’m ready to go. Get your stuff together. You will need your smoker, some good foil, a can of peach nectar, a bottle of Agave syrup, and a package of brown sugar. You will need this stuff later. I also use a clean spray bottle, and apple juice. Step 4. Make your fire, or turn on your electric smoker. In this example I’m using my portable charcoal smoker. I got this for only $40. I then modified it to be useful. Once modified, these guys actually work very well. Trust me, your food DOES NOT KNOW how expensive your smoker is. Someone who tells you that you need to spend a bunch of money on a smoker is an idiot. I also have an electric smoker that stays in my backyard. It’s cleaner and larger so I can smoke more food. But this little $40 one works great for going camping. Here is what my fire-bowl looks like. I leave a space in the middle open, and place cold charcoal and wood chucks in a circle going outwards. This makes it so when I dump the hot coals down the middle, they will slowly burn outwards, hitting different wood chucks at different times, allowing me to go 4-5 hours without having to even touch my fire. For ribs, I use apple and pecan wood. Pecan works for anything. Apple or any fruit wood is excellent for pork. So now I make my hot charcoal with a chimney only about half-full. I found a great use for that side-burner on my grill that I never use. It makes a fantastic chimney starter. You never use fluids of any kind, nor ever use that stupid charcoal that has lighter fluid built into it. Never, ever, ever. Step 5. Smoke. Add your ribs in the racks and stack them up in your smoker. I have a digital thermometer on a probe that I use to keep track of the temp in the smoker. I just lay the probe on the top rack and shut the lid. This cheap guy is a little harder to maintain the right temperature of around 225 F, so I do have to keep my eye on it more than my electric one or a more expensive charcoal one with the cool gadgets that regulate your temp for you. Every hour, spray apple juice all over your ribs using that spray bottle. After about 3 hours, you should have a very good crust (called the Bark) on your ribs. Once you have the Bark where you want it, carefully remove your ribs and place them in a tray. We are now ready for a very important part to make the flavor. Get a large piece of foil and place one rib section on it. Splash some of the peach nectar on it, and then a drizzle of the Agave syrup. Then, use your gloved hand to pack on some brown sugar. Do this on BOTH sides, and then completely wrap it up TIGHT in the foil. Do this for each rib section, and then place all the wrapped sections back into the smoker for another 4 to 6 hours. This is where the meat will get tender and flavorful. The first three hours is only to make the smoke bark. You don’t need smoke anymore, since the ribs are wrapped, you only need to keep the heat around 225 for the next 4-6 hours. Obviously you don’t spray anymore. Just time and slow heat. Be patient. It’s actually really hard to overdo it. You can let them go longer, and all that will happen is they will get even MORE tender!!! If you take them out too soon, they will be tough. How do you know? Take out one package (use long tongs) and open it up. If you grab a bone with your tongs and it just falls apart and breaks away from the rest of the meat, you are done!!! Enjoy!!! Step 6. Eat. It pulls apart like this when it’s done. By the way, smoking tri-tip is way easier. Just rub it with the same rub, and put in your smoker for about 2.5 hours at 250 F. That’s it. Low-maintenance. It comes out like this, with a fantastic smoke ring and amazing flavor. Thanks, and I will put up another good tip, about the ZFSSA, around the end of November. Steve

  • Do you tend to write your own name or your company name in your code?

    - by Connell Watkins
    I've been working on various projects at home and at work, and over the years I've developed two main APIs that I use in almost all AJAX based websites. I've compiled both of these into DLLs and called the namespaces Connell.Database and Connell.Json. My boss recently saw these namespaces in a software documentation for a project for the company and said I shouldn't be using my own name in the code. (But it's my code!) One thing to bear in mind is that we're not a software company. We're an IT support company, and I'm the only full-time software developer here, so there's not really any procedures on how we should write software in the company. Another thing to bear in mind is that I do intend on one day releasing these DLLs as open-source projects. How do other developers group their namespaces within their company? Does anyone use the same class libraries in personal and in work projects? Also does this work the other way round? If I write a class library entirely at work, who owns that code? If I've seen the library through from start to finish, designed it and programmed it. Can I use that for another project at home? Thanks, Update I've spoken to my boss about this issue and he agrees that they're my objects and he's fine for me to open-source them. Before this conversation I started changing the objects anyway, which was actually quite productive and the code now suits this specific project more-so than it did previously. But thank you to everyone involved for a very interesting debate. I hope all this text isn't wasted and someone learns from it. I certainly did. Cheers,

  • Should I start making connections even if I'm not ready for a job yet?

    - by James
    The first job is always the hardest to get and I'm not exception. I'm 23 years old and I have no college degree but planned on going to college this year if all goes well (CS of course). I'm self-studying java right now. I know most of the topics related to the language besides the more advanced topics and I'm beginning to look at open source projects. I would like to find a job (at least a part time job) after a year or two when I'll gain more experience and learn more about java technologies and other technologies that interest me. Finding a job will be a bit difficult because most of the people (or a lot of them at least) at my current age already have 2 years or more of experience, so I will be somewhat disadvantaged. Should I start building connections and joining websites such as linkedin ? I never bothered to look into it because I'm not much of a social network person. If I start contributing to open source projects and create personal projects for 2 years could I apply for jobs that require 1-2 years of experience? Does this experience count ?

  • Python or Ruby in 2011.

    - by Sleeper Smith
    What I'm really asking is, in the current services and technologies provided, which is a more "useful" language? Which one has more opportunity? Some background info first. I'm a .net C# dev for 5 years. Having done a few projects on Amazon AWS, I'm looking to start a few projects of my own. But Azure's too expensive, and AWS has too much management overhead. My current choice is Google App Engine and Python. Logical enough. But what I want to ask here is this: In Linux world, which is more useful? Recently heard about Heroku for Ruby. How viable is this? Looking at the pricing model indicates that it's more expensive. Which one has more up-to-date and exciting open source projects? For instance Trac is just plain out dated compared to Redmine. One of the big reason pulling me for Ruby is Redmine. Implementations? IronPython/IronRuby/JRuby etc etc. Which one is more standardised and more implementation agnostic? Which one is easier to port between Windows/Linux? Anyway, your input and thoughts are greatly appreciated. thanks.

  • Can I assume interface oriented programming as a good object oriented programming?

    - by david
    I have been programming for decades but I have not been used to object oriented programming. But for recenet years, I had a great opportunity to learn OOP, its principles, and a lot of patterns that are great. Since I've learned OOP, I tried to apply them to a couple of projects and found those projects successful. Unfortunately I didn't follow extreme programming that suggests writing test first, mainly because their time frame were tight. What I did for those projects were Identify all necessary classes and create them with proper properties and methods whenever there is dependency between classes, write interface between them see if there is any patterns for certain relationships between classes to replace By successful, I meant that it was quick development effort, the classes can be reused better, and flexible enough so that another programmer does not have to change something else to fix another part. But I wonder if this is a good practice. Of course, I know I need to put writing unit tests first in my work process. But other than that, is there any problem with this approach - creating lots of interfaces - in long term?

  • Why isn't there a culture of paying for frameworks?

    - by Marty Pitt
    One of the side effects of the recent trend of "Lean" startups, and the app store era, is that consumers are more acclimatised to paying small prices for small games / products. Eg.: Online SAAS that charges ~$5 / month (the basecamp style of product) Games which are short, fun, and cheap ($0.99 from the app store This market has been defined by "doing one thing well, and charging people for it." DHH of Rails / 37 Signals fame argues that if your website isn't going to make money, don't bother making it. Why doesn't the same rule apply to frameworks? There are lots of software framework projects out there - many which are mature and feature-rich, which offer developers significant value, yet there doesn't seem to be a market or culture of paying for these. It seems that the projects which do charge money are often things like UI component toolsets, and are often marginalized in favour of free alternatives. Why is this? Surely programmers / businesses see the value in contributing back to projects such as Ruby, Rails, Hibernate, Spring, Ant, Groovy, Gradle, (the list goes on). I'm not suggesting that these frameworks should start charging for anyone who wants to use them, but that there must be a meaningful business model that would allow the developers to earn money from the time they invest developing the framework. Any thoughts as to why this model hasn't emerged / succeeded?

  • POP Forums will be at Mix!

    - by Jeff
    If you've never been to Mix, you're missing out on what is arguably one of the best conferences that Microsoft does. I'm not just saying that because I work here... I felt that way before, having been to most of them. The breadth of people and disciplines make it a really exciting event that pushes it well beyond the "Redmond bubble," as I like to call it. You should go.In any case, there's an Open Source Fest happening the night before Mix starts, on Monday, from 6 to 9 p.m. There will be people there representing a ton of great projects, some as enormous as Umbraco, as well as people doing SDK's, controls and other neat stuff. Best of all, you get to vote for your favorites. Unless your favorite is Orchard, because Microsoft is sponsoring that directly. Or if it's POP Forums, not because Microsoft is sponsoring it, but because that's where I work in my day job. No prizes for me! Come by and say hello. I think the app will be nearly final by then, and it's already running on MouseZoom, one of my little side projects.The quality and diversity of open source projects around the Microsoft stack just keeps getting better. Our platform is also pretty great at running stuff we don't make. This will be a pretty exciting Mix. Can't wait!

  • From TFS to Git

    - by Saeed Neamati
    I'm a .NET developer and I've used TFS (team foundation server) as my source control software many times. Good features of TFS are: Good integration with Visual Studio (so I do almost everything visually; no console commands) Easy check-out, check-in process Easy merging and conflict resolution Easy automated builds Branching Now, I want to use Git as the backbone, repository, and source control of my open source projects. My projects are in C#, JavaScript, or PHP language with MySQL, or SQL Server databases as the storage mechanism. I just used github.com's help for this purpose and I created a profile there, and downloaded a GUI for Git. Up to this part was so easy. But I'm almost stuck at going along any further. I just want to do some simple (really simple) operations, including: Creating a project on Git and mapping it to a folder on my laptop Checking out/checking in files and folders Resolving conflicts That's all I need to do now. But it seems that the GUI is not that user friendly. I expect the GUI to have a Connect To... or something like that, and then I expect a list of projects to be shown, and when I choose one, I expect to see the list of files and folders of that project, just like exploring your TFS project in Visual Studio. Then I want to be able to right click a file and select check-in... or check-out and stuff like that. Do I expect much? What should I do to easily use Git just like TFS? What am I missing here?

  • Migration of PowerBuilder application to multiplatform

    - by Alex Bibiano
    I developed a client/server application with PowerBuilder in the past for medical clinics and done maintenance for it until now. Now, some clients are asking me to develop a release for Mac/Linux and need some advice about what programming language/technology is best suited for it and the learning curve. It’s not a very very big program but I’m the only developer and have done it in my spare time. PowerBuilder is very productive for this kind of projects (database centric), but it’s not multiplatform and it’s hard to sell PowerBuilder application now days (web, .NET, java sells a lot better with his marketing). My programming skills: - I studied C and C++ in the past (university) but never used it on real projects - Have some Java experience but not in desktop applications - Some experience with Ruby on Rails for web projects - Good skills with PowerBuilder and C# (.NET) (there are my main developing languages) My first dilemma is if I change the desktop application to a web interface, but I think the user will lose some user-experience, and some doctors don’t have a clinic (they are alone at home with my software). I think installing a web application (with webserver) for one user will be overwhelming. If I continue developing desktop application, what is at the moment a good framework/toolset to learn having my skills? Somebody has had similar experiences? A lot of thanks

  • What's cool about Lisp nowadays? [closed]

    - by Kos
    Possible Duplicates: Why is Lisp useful? Is LISP still useful in today's world? Which version is most used? First of all, let me clarify: I'm aware of Lisp's place in history, as well as in education. I'm asking about its place in practical application, as of 2011. The question is: What features of Lisp make it the preferred choice for projects today? It's widely used in various AI areas as far as I know, and probably also elsewhere. I can imagine projects choosing, for instance... Python because of its concise, readable syntax and it being dynamic, Haskell for being pure functional with a powerful type system, Matlab/Octave for the focus on numerics and big standard libraries, Etc. When should I consider Lisp the proper language for a given problem? What language features make it the preferred choice then? Is its "purity and generality" an advantage which makes it a better choice for some subset of projects than the modern languages? edit- On your demand, a little rephrase (or simply a tl;dr) to make this more specific: a) What problems are solvable with Lisp much more easily than with more common, modern languages like Python or C# (or even F# or Scala)? b) What language features specific for Lisp make it the best choice for those problems?

  • New Responsibilities

    - by Robert May
    With the start of the new year, I’m starting new responsibilities at Veracity. One responsibility that is staying constant is my love and evangelism of Agile.  In fact, I’ll be spending more time ensuring that all Veracity teams are performing agile, Scrum specifically, in a consistent manner so that all of our clients and consultants have a similar experience. Imagine, if you will, working for a consulting company on a project.  On that project, the project management style is Waterfall in iterations.  Now you move to another project and in that project, you’re doing real Scrum, but in both cases, you were told that what you were doing was Scrum.  Rather confusing.  I’ve found, however, that this happens on many teams and many projects.  Most companies simply aren’t disciplined enough to do Scrum.  Some think that being Agile means not being disciplined.  The opposite is true! So, my goals for Veracity are to make sure that all of our consultants have a consistent feel for Scrum and what it is and how it works and then to make sure that on the projects they’re assigned to, Scrum is appropriately applied for their situation.  This will help keep them happier, but also make switching to other projects easier and more consistent.  If we aren’t doing the project management on the project, we’ll help them know what good Agile practices should look like so that they can give good advice to the client, and so that if they move to another project, they have a consistent feel. I’m really looking forward to these new duties. Technorati Tags: Agile,Scrum

  • Learning Programming during the job?

    - by Hossein
    Introduction: I have read and heard advice, about learning programming by accepting programming projects. I need real assistance to understand this, because: Problem: Although, it would seem to me that one would gain much more technical knowledge by doing, real world projects, if one doesn't know much about a technology, it would add much more risk to the actual delivery of the final product! Even the smallest of real world projects could be too much for a newbie. There is a contradiction here: You need to know the job to do it! and It's recommended to do the job, in order to learn it! Question: Any personal experiences in this case would be very pleasant to know while describing: How new was the subject to you? didn't have a clue at all? Or, did you have experience with similar technologies? Was it a solo project or were you in a team? If team, then did others help you with learning it? Did it work as expected? Did you deliver on time? Do you recommend this approach to others as well?

  • How can I make myself better at programming working at a shi* job ?

    - by Scrooge
    I recently graduated with an Engineering degree in Computer Science, but my employer (a mid-sized software company) is not using my logical and programming skills. I want to move to a better opportunity but how do I do that since my experience here is not going to count as much? How do I get a better programming job? The worst part is that I am still reading from books (and not writing code myself) even after I have started working. They are paying me a standard entry level Indian IT job rate but I really dont care. It's not worth it. Please advise as to how I can do something worthwhile. (I have studied C++; Core Java; Ruby On Rails ..made a couple of academic projects but no relevant practical real world experience). Just to make things easier .. let me list a few basic queries How I get better at programming without a good project at my company? Please suggest projects where I can learn to write practical code (platform doesn't matter) Best place to take part in open source development? Is it possible that I earn slightly more while I learn? (apart from my sh** job I mean) What kind of practical projects are best suited for me? (ie for an entry level programmer)

  • Need ideas for an innovation week

    - by slandau
    So 4 times a year we have an innovation week (to even out the odd sprint releases). This whole week is dedicated to experimenting with new technology/ideas that could potentially help progress the software department or the company as a whole, and serve as sort of a starting point for new ideas and brainstorming. For example, the last one contained a lot of projects. One was the re-design of our web app into more of a Web 2.0 look and feel using JQuery and a lot of cool CSS tricks. Another was a proposal for a new bug tracking software as opposed to the clearly outdated one we use, and another was a very cool JQuery/Js design that could show the same page to multiple users on different computers and allow each of them to take "charge" of the page, disabling the other one from doing anything, and vice versa, seeing all updates in real time -- sort of like Netmeeting through Js. Well, this is my first one as a new employee so I wanted to think of something cool. We get one week (anywhere from 40-60 hours or so), and we usually pair up or do this in groups of 3-4, depending on how many projects there are. Projects have to get approved but usually that doesn't prove to be too difficult. We are in the financial analysis software industry if the domain was leading you guys to think of anything helpful. I am primarily working on a web app in MVC 2 at the moment using a lot of JQuery and a C# backend. Do you guys have any idea of something that would be cool/beneficial/worth it?

  • Towards Ultra-Reusability for ADF - Adaptive Bindings

    - by Duncan Mills
    The task flow mechanism embodies one of the key value propositions of the ADF Framework, it's primary contribution being the componentization of your applications and implicitly the introduction of a re-use culture, particularly in large applications. However, what if we could do more? How could we make task flows even more re-usable than they are today? Well one great technique is to take advantage of a feature that is already present in the framework, a feature which I will call, for want of a better name, "adaptive bindings". What's an adaptive binding? well consider a simple use case.  I have several screens within my application which display tabular data which are all essentially identical, the only difference is that they happen to be based on different data collections (View Objects, Bean collections, whatever) , and have a different set of columns. Apart from that, however, they happen to be identical; same toolbar, same key functions and so on. So wouldn't it be nice if I could have a single parametrized task flow to represent that type of UI and reuse it? Hold on you say, great idea, however, to do that we'd run into problems. Each different collection that I want to display needs different entries in the pageDef file and: I want to continue to use the ADF Bindings mechanism rather than dropping back to passing the whole collection into the taskflow   If I do use bindings, there is no way I want to have to declare iterators and tree bindings for every possible collection that I might want the flow to handle  Ah, joy! I reply, no need to panic, you can just use adaptive bindings. Defining an Adaptive Binding  It's easiest to explain with a simple before and after use case.  Here's a basic pageDef definition for our familiar Departments table.  <executables> <iterator Binds="DepartmentsView1" DataControl="HRAppModuleDataControl" RangeSize="25"             id="DepartmentsView1Iterator"/> </executables> <bindings> <tree IterBinding="DepartmentsView1Iterator" id="DepartmentsView1">   <nodeDefinition DefName="oracle.demo.model.vo.DepartmentsView" Name="DepartmentsView10">     <AttrNames>       <Item Value="DepartmentId"/>         <Item Value="DepartmentName"/>         <Item Value="ManagerId"/>         <Item Value="LocationId"/>       </AttrNames>     </nodeDefinition> </tree> </bindings>  Here's the adaptive version: <executables> <iterator Binds="${pageFlowScope.voName}" DataControl="HRAppModuleDataControl" RangeSize="25"             id="TableSourceIterator"/> </executables> <bindings> <tree IterBinding="TableSourceIterator" id="GenericView"> <nodeDefinition Name="GenericViewNode"/> </tree> </bindings>  You'll notice three changes here.   Most importantly, you'll see that the hard-coded View Object name  that formally populated the iterator Binds attribute is gone and has been replaced by an expression (${pageFlowScope.voName}). This of course, is key, you can see that we can pass a parameter to the task flow, telling it exactly what VO to instantiate to populate this table! I've changed the IDs of the iterator and the tree binding, simply to reflect that they are now re-usable The tree binding itself has simplified and the node definition is now empty.  Now what this effectively means is that the #{node} map exposed through the tree binding will expose every attribute of the underlying iterator's collection - neat! (kudos to Eugene Fedorenko at this point who reminded me that this was even possible in his excellent "deep dive" session at OpenWorld  this year) Using the adaptive binding in the UI Now we have a parametrized  binding we have to make changes in the UI as well, first of all to reflect the new ID that we've assigned to the binding (of course) but also to change the column list from being a fixed known list to being a generic metadata driven set: <af:table value="#{bindings.GenericView.collectionModel}" rows="#{bindings.GenericView.rangeSize}"         fetchSize="#{bindings.GenericView.rangeSize}"           emptyText="#{bindings.GenericView.viewable ? 'No data to display.' : 'Access Denied.'}"           var="row" rowBandingInterval="0"           selectedRowKeys="#{bindings.GenericView.collectionModel.selectedRow}"           selectionListener="#{bindings.GenericView.collectionModel.makeCurrent}"           rowSelection="single" id="t1"> <af:forEach items="#{bindings.GenericView.attributeDefs}" var="def">   <af:column headerText="#{bindings.GenericView.labels[def.name]}" sortable="true"            sortProperty="#{def.name}" id="c1">     <af:outputText value="#{row[def.name]}" id="ot1"/>     </af:column>   </af:forEach> </af:table> Of course you are not constrained to a simple read only table here.  It's a normal tree binding and iterator that you are using behind the scenes so you can do all the usual things, but you can see the value of using ADFBC as the back end model as you have the rich pantheon of UI hints to use to derive things like labels (and validators and converters...)  One Final Twist  To finish on a high note I wanted to point out that you can take this even further and achieve the ultra-reusability I promised. Here's the new version of the pageDef iterator, see if you can notice the subtle change? <iterator Binds="{pageFlowScope.voName}"  DataControl="${pageFlowScope.dataControlName}" RangeSize="25"           id="TableSourceIterator"/>  Yes, as well as parametrizing the collection (VO) name, we can also parametrize the name of the data control. So your task flow can graduate from being re-usable within an application to being truly generic. So if you have some really common patterns within your app you can wrap them up and reuse then across multiple developments without having to dictate data control names, or connection names. This also demonstrates the importance of interacting with data only via the binding layer APIs. If you keep any code in the task flow generic in that way you can deal with data from multiple types of data controls, not just one flavour. Enjoy!

  • Release notes for 9/25/2012

    Below are the release notes from today's deployment. 1. With today’s deployment we’ve made some significant changes to the source code experience. First of all, you’ll noticed that we moved the Source Code tab closer to the project home tab.   We believe that this will help make source code more discoverable and emphasizes our focus on developer collaboration. The next thing you’ll notice is that when you click on the Source Code tab, you will immediately be browsing code. We want to get you to the project source code in a minimum number of clicks, and this change helps get you there. The changeset history is still there, which brings us to the next change… We implemented an action bar in the source code section, which will make certain actions more discoverable, including forking, cloning, and downloading source code The popups in the action bar will help you perform the tasks you need to do when contributing to projects, as well as managing your own projects. Take a look at how easy it is to find the clone/connection URL now! 2. The second exciting thing we turned on this week is the ability to enable Windows Azure Web Sites to build and deploy your project source code (for Git source code projects). You can read more about how to do this in Mark's post here. 3. We also made some improvements in other areas this week: Made some improvements to screen reader accessibility Fixed some minor UI issues in the browse source code page We'd love to have your feedback on the new changes to the source code tab. Please let us know what you think on our suggestions page, send us a message on Twitter @codeplex, or you can reach Mark Groves directly @mgroves84

  • Do you tend to write your own name or your company name in your code?

    - by Connell Watkins
    I've been working on various projects at home and at work, and over the years I've developed two main APIs that I use in almost all AJAX based websites. I've compiled both of these into DLLs and called the namespaces Connell.Database and Connell.Json. My boss recently saw these namespaces in a software documentation for a project for the company and said I shouldn't be using my own name in the code. (But it's my code!) One thing to bear in mind is that we're not a software company. We're an IT support company, and I'm the only full-time software developer here, so there's not really any procedures on how we should write software in the company. Another thing to bear in mind is that I do intend on one day releasing these DLLs as open-source projects. How do other developers group their namespaces within their company? Does anyone use the same class libraries in personal and in work projects? Also does this work the other way round? If I write a class library entirely at work, who owns that code? If I've seen the library through from start to finish, designed it and programmed it. Can I use that for another project at home? Thanks, Update I've spoken to my boss about this issue and he agrees that they're my objects and he's fine for me to open-source them. Before this conversation I started changing the objects anyway, which was actually quite productive and the code now suits this specific project more-so than it did previously. But thank you to everyone involved for a very interesting debate. I hope all this text isn't wasted and someone learns from it. I certainly did. Cheers,

  • Parameterized Django models

    - by mgibsonbr
    In principle, a single Django application can be reused in two or more projects, providing functionality relevent to both. That implies that the same database structure (tables and relations) will be re-created identically in different databases, and most times this is not a problem (assuming the projects/databases are unrelated - for instance when someone downloads a complete app to use in their own projects). Sometimes, however, the models must be "tweaked" a little to better fit the problem needs. This can be accomplished by forking the app, but I wondered if there wouldn't be a better option in cases where the app designer can anticipate the most common customizations. For instance, if I have a model that could relate to another as one-to-one or one-to-many, I could specify the unique property as a parameter, that can be specified in the project's settings: class This(models.Model): other = models.ForeignKey(Other, unique=settings.OTHER_TO_THIS) Or if a model can relate to many others, I could create an intermediate table for each of them (thus enforcing referential integrity) instead of using generic fks: for related in settings.MODELS_RELATED_TO_OTHER: model_name = '%s_Other' % related globals()[model_name] = type(model_name, (models.Model,) { me:models.ForeignKey(find_model_class(related)), other:models.ForeignKey(Other), # Some other properties all intersection tables must have }) Etc. Let me stress out that I'm not proposing to change the models at runtime nor anything like that; once the parameters were defined and syncdb called for the first time, those parameters are not to be changed again (unless you're doing a schema migration). Is this a good design? Are there better ways to accomplish the same thing, or maybe drawbacks I coulnd't anticipate? This technique is meant to be used sparingly (only on apps meant to be reused in wildly different contexts, and only when a specific need of customization can be detected while the app model is being designed).

  • To PHP or Not to PHP? [closed]

    - by Vad
    Should I learn PHP in depth for my smaller projects or not? My main knowledge is Java/JavaScript for the web. My old small projects were written in classic ASP. However, ASP had its days. Now I am looking into going deeper with another scripting language which I can use for small website projects. Though I know PHP on a basic level I never liked PHP. But I have to admit it is so widely used that I better start liking it. And all hosting services offer mostly PHP solutions. However, there is quite a number of issues with PHP when I google for it. Developers seem to not like it a lot. I wish I would use server-side JavaScript for all my needs, but hosting is an issue plus many small businesses already want to improve their existing PHP sites. And lastly, say I want to create a web app for distribution. PHP sounds like the best bet. Or am I wrong?

  • Can't get directory listing on my Apache to work.

    - by joon
    Hi, I'm having trouble enabling the directory listing on apache. I did it a few weeks ago but had to reinstall cause my Wubi ran out of space, and now I can't get it to work and it's driving me crazy. I have a folder /home/joon/Dropbox/Projects/apache, which I want to set as the root for my apache. Here's the first lines of the 'default' file in the sites-available folder: <VirtualHost *:8888> ServerAdmin webmaster@localhost DocumentRoot /home/joon/Dropbox/Projects/apache <Directory /home/joon/Dropbox/Projects/apache> Options +Indexes FollowSymLinks AllowOverride None The rest is unchanged. Ports.conf is set to Listen 8888. I thought the +Indexes should do it, but I must have overlooked something. I get a 403, forbidden. "You don't have permission to access / on this server." If I input the url of an image, http://127.0.0.1:8888/joon/bin/1chart.png, it displays, but no directory listing. Please help.

  • Any empirical evidence on the efficacy of CMMI?

    - by mehaase
    I am wondering if there are any studies that examine the efficacy of software projects in CMMI-oriented organizations. For example, are CMMI organizations more likely to finish projects on time and/or on budget than non-CMMI organizations? Edit for clarification: CMMI stands for "Capability Maturity Model Integration". It's developed by the Software Engineering Institute at Carnegie-Mellon University (SEI-CMU). It's not a certification, but there are various companies that will "appraise" your organization to various levels of CMMI, such as level 2 and level 3. (I believe CMMI level 1 is an animalistic, Hobbesian free-for-all that nobody aspires to. In other words, everybody is at least CMMI level 1, even if you've never heard of CMMI before.) I'm definitely not an expert, but I believe that an organization can be appraised for CMMI levels within different scopes of work: i.e. service delivery, software development, foobaring, etc. My question is focused on the software development appraisal: is an organization that has been appraised to CMMI Level X for software projects more likely to finish a software project on time and on budget than another organization that has not been appraised to CMMI Level X? However, in the absence of hard data about software-oriented CMMI, I'd be interested in the effect that CMMI appraisals have on other activities as well. I originally asked the question because I've seen various studies conducted on software (e.g. the essays in The Mythical Man Month refer to numerous empirical studies, as does McConnell's Code Complete), so I know that there are organizations performing empirical studies of software development.
