  • Have you changed your coding style recently? It wasn't hard wasn't it?

    - by Ernelli
    I've used to write code in C-like languages using the Allman style, regarding the position of braces. void foo(int bar) { if(bar) { //... } else return; //... } Now the last two years I have been working mostly in JavaScript and when we adopted jslint as part of our QA process, I had to adopt to the Crockford way of doing things. So I had to change the coding style into: function foo(bar) { if (bar) { //... } else { return; } //... } Now apart from comparing a C/C++ example with JavaScript, I must say that my JavaScript-Crockford-coding style now has spread into my C/C++/Java coding when I revise old projects and work on code in those languages that for example has no problem with single line statements or ambiguous newline insertion. I used to consider the later format very awkward, I have never had any problems with adapting my coding style to the one chosen by my predecessors, except for when I was a Junior developer mostly being the solve developer on legacy projects and the first thing I did was to change the indenting style. But now after a couple of months I consider the Allman style a little bit too spacious and feel more comfortable with the K&R-like style. Have you changed your coding style during your career?

  • The future for Microsoft

    - by Scott Dorman
    Originally posted on: http://geekswithblogs.net/sdorman/archive/2013/10/16/the-future-for-microsoft.aspxMicrosoft is in the process of reinventing itself. While some may argue that it’s “too little, too late” or that their growing consumer-focused strategy is wrong, the truth of the situation is that Microsoft is reinventing itself into a new company. While Microsoft is now calling themselves a “devices and services” company, that’s not entirely accurate. Let’s look at some facts: Microsoft will always (for the long-term foreseeable future) be financially split into the following divisions: Windows/Operating Systems, which for FY13 made up approximately 24% of overall revenue. Server and Tools, which for FY13 made up approximately 26% of overall revenue. Enterprise/Business Products, which for FY13 made up approximately 32% of overall revenue. Entertainment and Devices, which for FY13 made up approximately 13% of overall revenue. Online Services, which for FY13 made up approximately 4% of overall revenue. It is important to realize that hardware products like the Surface fall under the Windows/Operating Systems division while products like the Xbox 360 fall under the Entertainment and Devices division. (Presumably other hardware, such as mice, keyboards, and cameras, also fall under the Entertainment and Devices division.) It’s also unclear where Microsoft’s recent acquisition of Nokia’s handset division will fall, but let’s assume that it will be under Entertainment and Devices as well. Now, for the sake of argument, let’s assume a slightly different structure that I think is more in line with how Microsoft presents itself and how the general public sees it: Consumer Products and Devices, which would probably make up approximately 9% of overall revenue. Developer Tools, which would probably make up approximately 13% of overall revenue. Enterprise Products and Devices, which would probably make up approximately 47% of overall revenue. Entertainment, which would probably make up approximately 13% of overall revenue. Online Services, which would probably make up approximately 17% of overall revenue. (Just so we’re clear, in this structure hardware products like the Surface, a portion of Windows sales, and other hardware fall under the Consumer Products and Devices division. I’m assuming that more of the income for the Windows division is coming from enterprise/volume licenses so 15% of that income went to the Enterprise Products and Devices division. Most of the enterprise services, like Azure, fall under the Online Services division so half of the Server and Tools income went there as well.) No matter how you look at it, the bulk of Microsoft’s income still comes from not just the enterprise but also software sales, and this really shouldn’t surprise anyone. So, now that the stage is set…what’s the future for Microsoft? The future I see for Microsoft (again, this is just my prediction based on my own instinct, gut-feel and publicly available information) is this: Microsoft is becoming a consumer-focused enterprise company. Let’s look at it a different way. Microsoft is an enterprise-focused company trying to create a larger consumer presence.  To a large extent, this is the exact opposite of Apple, who is really a consumer-focused company trying to create a larger enterprise presence. The major reason consumer-focused companies (like Apple) have started making in-roads into the enterprise is the “bring your own device” phenomenon. Yes, Apple has created some “game-changing” products but their enterprise influence is still relatively small. Unfortunately (for this blog post at least), Apple provides revenue in terms of hardware products rather than business divisions, so it’s not possible to do a direct comparison. However, in the interest of transparency, from Apple’s Quarterly Report (filed 24 July 2013), their revenue breakdown is: iPhone, which for the 3 months ending 29 June 2013 made up approximately 51% of revenue. iPad, which for the 3 months ending 29 June 2013 made up approximately 18% of revenue. Mac, which for the 3 months ending 29 June 2013 made up approximately 14% of revenue. iPod, which for the 3 months ending 29 June 2013 made up approximately 2% of revenue. iTunes, Software, and Services, which for the 3 months ending 29 June 2013 made up approximately 11% of revenue. Accessories, which for the 3 months ending 29 July 2013 made up approximately 3% of revenue. From this, it’s pretty clear that Apple is a consumer-and-hardware-focused company. At this point, you may be asking yourself “Where is all of this going?” The answer to that lies in Microsoft’s shift in company focus. They are becoming more consumer focused, but what exactly does that mean? The biggest change (at least that’s been in the news lately) is the pending purchase of Nokia’s handset division. This, in combination with their Surface line of tablets and the Xbox, will put Microsoft squarely in the realm of a hardware-focused company in addition to being a software-focused company. That can (and most likely will) shift the revenue split to looking at revenue based on software sales (both consumer and enterprise) and also hardware sales (mostly on the consumer side). If we look at things strictly from a Windows perspective, Microsoft clearly has a lot of irons in the fire at the moment. Discounting the various product SKUs available and painting the picture with broader strokes, there are currently 5 different Windows-based operating systems: Windows Phone Windows Phone 7.x, which runs on top of the Windows CE kernel Windows Phone 8.x+, which runs on top of the Windows 8 kernel Windows RT The ARM-based version of Windows 8, which runs on top of the Windows 8 kernel Windows (Pro) The Intel-based version of Windows 8, which runs on top of the Windows 8 kernel Xbox The Xbox 360, which runs it’s own proprietary OS. The Xbox One, which runs it’s own proprietary OS, a version of Windows running on top of the Windows 8 kernel and a proprietary “manager” OS which manages the other two. Over time, Windows Phone 7.x devices will fade so that really leaves 4 different versions. Looking at Windows RT and Windows Phone 8.x paints an interesting story. Right now, all mobile phone devices run on some sort of ARM chip and that doesn’t look like it will change any time soon. That means Microsoft has two different Windows based operating systems for the ARM platform. Long term, it doesn’t make sense for Microsoft to continue supporting that arrangement. I have long suspected (since the Surface was first announced) that Microsoft will unify these two variants of Windows and recent speculation from some of the leading Microsoft watchers lends credence to this suspicion. It is rumored that upcoming Windows Phone releases will include support for larger screen sizes, relax the requirement to have a hardware-based back button and will continue to improve API parity between Windows Phone and Windows RT. At the same time, Windows RT will include support for smaller screen sizes. Since both of these operating systems are based on the same core Windows kernel, it makes sense (both from a financial and development resource perspective) for Microsoft to unify them. The user interfaces are already very similar. So similar in fact, that visually it’s difficult to tell them apart. To illustrate this, here are two screen captures: Other than a few variations (the Bing News app, the picture shown in the Pictures tile and the spacing between the tiles) these are identical. The one on the left is from my Windows 8.1 laptop (which looks the same as on my Surface RT) and the one on the right is from my Windows Phone 8 Lumia 925. This pretty clearly shows that from a consumer perspective, there really is no practical difference between how these two operating systems look and how you interact with them. For the consumer, your entertainment device (Xbox One), phone (Windows Phone) and mobile computing device (Surface [or some other vendors tablet], laptop, netbook or ultrabook) and your desktop computing device (desktop) will all look and feel the same. While many people will denounce this consistency of user experience, I think this will be a good thing in the long term, especially for the upcoming generations. For example, my 5-year old son knows how to use my tablet, phone and Xbox because they all feature nearly identical user experiences. When Windows 8 was released, Microsoft allowed a Windows Store app to be purchased once and installed on as many as 5 devices. With Windows 8.1, this limit has been increased to over 50. Why is that important? If you consider that your phone, computing devices, and entertainment device will be running the same operating system (with minor differences related to physical hardware chipset), that means that I could potentially purchase my sons favorite Angry Birds game once and be able to install it on all of the devices I own. (And for those of you wondering, it’s only 7 [at the moment].) From an app developer perspective, the story becomes even more compelling. Right now there are differences between the different operating systems, but those differences are shrinking. The user interface technology for both is XAML but there are different controls available and different user experience concepts. Some of the APIs available are the same while some are not. You can’t develop a Windows Phone app that can also run on Windows (either Windows Pro or RT). With each release of Windows Phone and Windows RT, those difference become smaller and smaller. Add to this mix the Xbox One, which will also feature a Windows-based operating system and the same “modern” (tile-based) user interface and the visible distinctions between the operating systems will become even smaller. Unifying the operating systems means one set of APIs and one code base to maintain for an app that can run on multiple devices. One code base means it’s easier to add features and fix bugs and that those changes become available on all devices at the same time. It also means a single app store, which will increase the discoverability and reach of your app and consolidate revenue and app profile management. Now, the choice of what devices an app is available on becomes a simple checkbox decision rather than a technical limitation. Ultimately, this means more apps available to consumers, which is always good for the app ecosystem. Is all of this just rumor, speculation and conjecture? Of course, but it’s not unfounded. As I mentioned earlier, some of the prominent Microsoft watchers are also reporting similar rumors. However, Microsoft itself has even hinted at this future with their recent organizational changes and by telling developers “if you want to develop for Xbox One, start developing for Windows 8 now.” I think this pretty clearly paints the following picture: Microsoft is committed to the “modern” user interface paradigm. Microsoft is changing their release cadence (for all products, not just operating systems) to be faster and more modular. Microsoft is going to continue to unify their OS platforms both from a consumer perspective and a developer perspective. While this direction will certainly concern some people it will excite many others. Microsoft’s biggest failing has always been following through with a strong and sustained marketing strategy that presents a consistent view point and highlights what this unified and connected experience looks like and how it benefits consumers and enterprises. We’ve started to see some of this over the last few years, but it needs to continue and become more aggressive and consistent. In the long run, I think Microsoft will be able to pull all of these technologies and devices together into one seamless ecosystem. It isn’t going to happen overnight, but my prediction is that we will be there by the end of 2016. As both a consumer and a developer, I, for one, am excited about the future of Microsoft.

  • Dilemma for growing a project: Open source volunteer developers VS closed source paid / revshare developers? [closed]

    - by giorgio79
    I am trying to grow my project, and I am vaccillating between some examples. Some options seem to be: 1. open sourcing the project to draw volunteer developers. Pros This would mean anyone can try and make some money off the code that would motivate them to contribute back and grow the project. Cons Existing bigger could easily copy and paste my work so far. They can also replicate without having access to the code, but that would take more time. I also thought of using AGPL license, but again, code can still be copied without redistribution. After all, enforcing a license costs a lot of money, and I cannot just say to a possible copycat that it seems you copied my code, show me what you got. 2. Keep the project closed source, but create some kind of a developer program where they get revshare Pros I keep the main rights for the project, but still generate interest by creating a developer program. Noone can copy code easily, just with some considerable effort, but make contributions easy as a breeze. I am also seeing many companies just open source a part of their projects, like Acquia does not open source its multisite setup, or github does not open source some of its core business. Cons Less attention from open source committed devs. Conclusion So option 2 seems the most secure, but would love some feedback.

  • No endpoint listening at.........

    - by Michael Stephenson
    I was having some very frustrating behaviour on our build server and while I found a number of articles online with similar error messages none of them helped me.  I thought I would just explain this here incase if helps me or anyone else in future.The error message we were getting is:There was no endpoint listening at http://localhostStubs.ExternalApplication/SampleService.svc that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more detailsOur scenario is as follows:We have a solution where a WCF service application hosting the WCF routing service is listening to the Windows Azure Service Bus Relay.  We have an acceptance test project in the solution which sends a message to the service bus which is then received by the WCF routing service and routed to SampleService.svc which is hosted in another IIS application on the same box.  A response is flowed back through to the test.  In the tests there are 5 scenarios simulating a successful message, and various error conditions.  On my developer machine it was working absolutely fine every time, and a clean build on my developer machine worked fine.  On the build server however one or more of the tests would fail each time with the above error message.  There didnt seem to be any pattern to which test would fail.The solution was building on a Windows 2008 R2 machine with IIS 7 and AppFabric Server installed with auto-start configured for the IIS Application which would be listening to service bus.After lots of searching online and looking at logs etc it turned out to be a simple solution to just restart the WAS service (Windows Process Activation Service) and the services it advised you to restart with it.  Hope this helps someone else

  • Is there something special about the number 65535?

    - by Nick Rosencrantz
    2¹6-1 & 25 = 25 (or? obviously ?) A developer asked me today what is bitwise 65535 & 32 i.e. 2¹6-1 & 25 = ? I thought at first spontaneously 32 but it seemed to easy whereupon I thought for several minutes and then answered 32. 32 seems to have been the correct answer but how? 65535=2¹6-1=1111111111111111 (but it doesn't seem right since this binary number all ones should be -1(?)), 32 = 100000 but I could not convert that in my head whereupon I anyway answered 32 since I had to answer something. Is the answer 32 in fact trivial? Is in the same way 2¹6-1 & 25-1 =31? Why did the developer ask me about exactly 65535? Binary what I was asked to evaluate was 1111111111111111 & 100000 but I don't understand why 1111111111111111 is not -1. Shouldn't it be -1? Is 65535 a number that gives overflow and how do I know that?

  • Essential roles for web application team

    - by jromero
    Some friends of mine came up with an idea for a web application which we (so far) think could be great. I made the analysis and all the early stages of the development process and I'm about to start the coding. I'm talking about something that is barely a mid-level project, so I consider one developer (myself) should be enough. The thing is that we are trying to assign roles to each one of us so we can be focused on our duties and have clear our responsibilities within the team. We are a crew of four people, three of us (my friends) are business people who would do the marketing, customer relationship, management and accounting stuff and I'm basically the developer. I have in mind to get them involved into the development process by giving them documentation to write and use them as testers, all of that besides the management duties they have. Perhaps someone out there have been in the same situation, so I would appreciate if the experience is shared so we can effectively give ourselves positions in the project based on what I explained above. Which are the essential roles or the optimal team layout so the idea can be developed successfully? The question is not strictly about programming, but it's related to build a software entrepreneurship beyond the code, that is something that I'm sure plenty of us are looking. Any help is really appreciated! Regards.

  • Running ADF Essentials in Tomcat

    - by Rodrigues, Raphael
    Oracle released a few days ago ADF Essentials, which is a free version of its Oracle ADF Framework. Oracle ADF Essentials can run on the Glassfish Application Server, well explained by Shay here  . Glassfish is also certified to run ADF Essentials Application. However, It could be possible to run ADF Essentials Applications in a Java EE Container. So, I’ll describe the steps to run the ADF Faces Rich Client demo application into a Tomcat 7. Before we start, you should download the files: • Apache Tomcat 7 : http://tomcat.apache.org/download-70.cgi • Oracle ADF Essentials 11.1.2.3 : http://www.oracle.com/technetwork/developer-tools/adf/downloads/index.html • Oracle ADF Faces Components Demo 11.1.2.3: http://www.oracle.com/technetwork/developer-tools/adf/downloads/index.html Steps: 1. Extract your tomcat 7. In my case, I choose D:\ apache-tomcat-7.0.29 2. Extract ADF Essentials zip file inside the %TOMCAT_HOME%\lib 3. Put the rcf-dvt-demo.war file inside the %TOMCAT_HOME%\webapps 4. Open the file %TOMCAT_HOME%\bin\catalina.bat (or .sh if you’re in linux environment) and add in the end of the line ‘set JAVA_OPTS=%JAVA_OPTS% %LOGGING_CONFIG%’ this -Xms1024m -Xmx1024m If you don’t do this, probably when you start you’ll see a OutOfMemory error. 5. Here is the little trick, tomcat does not come with jsf jar’s, so you have to put there. So, I went to the Oracle Jdeveloper 11.1.2 instalation and search for this files: • jsf-api.jar • jsf-impl.jar • glassfish.jstl_1.2.0.1.jar 6. You’re ready to start tomcat in %TOMCAT_HOME%\bin\startup.bat If everything is fine, you will be able to open your favourite browser and type http://localhost:8080/rcf-dvt-demo/faces/index.jspx

  • Evil DRY

    - by StefanSteinegger
    DRY (Don't Repeat Yourself) is a basic software design and coding principle. But there is just no silver bullet. While DRY should increase maintainability by avoiding common design mistakes, it could lead to huge maintenance problems when misunderstood. The root of the problem is most probably that many developers believe that DRY means that any piece of code that is written more then once should be made reusable. But the principle is stated as "Every piece of knowledge must have a single, unambiguous, authoritative representation within a system." So the important thing here is "knowledge". Nobody ever said "every piece of code". I try to give some examples of misusing the DRY principle. Code Repetitions by Coincidence There is code that is repeated by pure coincidence. It is not the same code because it is based on the same piece of knowledge, it is just the same by coincidence. It's hard to give an example of such a case. Just think about some lines of code the developer thinks "I already wrote something similar". Then he takes the original code, puts it into a public method, even worse into a base class where none had been there before, puts some weird arguments and some if or switch statements into it to support all special cases and calls this "increasing maintainability based on the DRY principle". The resulting "reusable method" is usually something the developer not even can give a meaningful name, because its contents isn't anything specific, it is just a bunch of code. For the same reason, nobody will really understand this piece of code. Typically this method only makes sense to call after some other method had been called. All the symptoms of really bad design is evident. Fact is, writing this kind of "reusable methods" is worse then copy pasting! Believe me. What will happen when you change this weird piece of code? You can't say what'll happen, because you can't understand what the code is actually doing. So better don't touch it anymore. Maintainability just died. Of course this problem is with any badly designed code. But because the developer tried to make this method as reusable as possible, large parts of the system get dependent on it. Completely independent parts get tightly coupled by this common piece of code. Changing on the single common place will have effects anywhere in the system, a typical symptom of too tight coupling. Without trying to dogmatically (and wrongly) apply the DRY principle, you just had a system with a weak design. Now you get a system which just can't be maintained anymore. So what can you do against it? When making code reusable, always identify the generally reusable parts of it. Find the reason why the code is repeated, find the common "piece of knowledge". If you have to search too far, it's probably not really there. Explain it to a colleague, if you can't explain or the explanation is to complicated, it's probably not worth to reuse. If you identify the piece of knowledge, don't forget to carefully find the place where it should be implemented. Reusing code is never worth giving up a clean design. Methods always need to do something specific. If you can't give it a simple and explanatory name, you did probably something weird. If you can't find the common piece of knowledge, try to make the code simpler. For instance, if you have some complicated string or collection operations within this code, write some general-purpose operations into a helper class. If your code gets simple enough, its not so bad if it can't be reused. If you are not able to find anything simple and reasonable, copy paste it. Put a comment into the code to reference the other copies. You may find a solution later. Requirements Repetitions by Coincidence Let's assume that you need to implement complex tax calculations for many countries. It's possible that some countries have very similar tax rules. These rules are still completely independent from each other, since every country can change it of its own. (Assumed that this similarity is actually by coincidence and not by political membership. There might be basic rules applying to all European countries. etc.) Let's assume that there are similarities between an Asian country and an African country. Moving the common part to a central place will cause problems. What happens if one of the countries changes its rules? Or - more likely - what happens if users of one country complain about an error in the calculation? If there is shared code, it is very risky to change it, even for a bugfix. It is hard to find requirements to be repeated by coincidence. Then there is not much you can do against the repetition of the code. What you really should consider is to make coding of the rules as simple as possible. So this independent knowledge "Tax Rules in Timbuktu" or wherever should be as pure as possible, without much overhead and stuff that does not belong to it. So you can write every independent requirement short and clean. DRYing try-catch and using Blocks This is a technical issue. Blocks like try-catch or using (e.g. in C#) are very hard to DRY. Imagine a complex exception handling, including several catch blocks. When the contents of the try block as well as the contents of the individual catch block are trivial, but the whole structure is repeated on many places in the code, there is almost no reasonable way to DRY it. try { // trivial code here using (Thingy thing = new thingy) { //trivial, but always different line of code } } catch(FooException foo) { // trivial foo handling } catch (BarException bar) { // trivial bar handling } catch { // trivial common handling } finally { // trivial finally block } The key here is that every block is trivial, so there is nothing to just move into a separate method. The only part that differs from case to case is the line of code in the body of the using block (or any other block). The situation is especially interesting if the many occurrences of this structure are completely independent: they appear in classes with no common base class, they don't aggregate each other and so on. Let's assume that this is a common pattern in service methods within the whole system. Examples of Evil DRYing in this situation: Put a if or switch statement into the method to choose the line of code to execute. There are several reasons why this is not a good idea: The close coupling of the formerly independent implementation is the strongest. Also the readability of the code and the use of a parameter to control the logic. Put everything into a method which takes a delegate as argument to call. The caller just passes his "specific line of code" to this method. The code will be very unreadable. The same maintainability problems apply as for any "Code Repetition by Coincidence" situations. Enforce a base class to all the classes where this pattern appears and use the template method pattern. It's the same readability and maintainability problem as above, but additionally complex and tightly coupled because of the base class. I would call this "Inheritance by Coincidence" which will not lead to great software design. What can you do against it: Ideally, the individual line of code is a call to a class or interface, which could be made individual by inheritance. If this would be the case, it wouldn't be a problem at all. I assume that it is no such a trivial case. Consider to refactor the error concept to make error handling easier. The last but not worst option is to keep the replications. Some pattern of code must be maintained in consistency, there is nothing we can do against it. And no reason to make it unreadable. Conclusion The DRY-principle is an important and basic principle every software developer should master. The key is to identify the "pieces of knowledge". There is code which can't be reused easily because of technical reasons. This requires quite a bit flexibility and creativity to make code simple and maintainable. It's not the problem of the principle, it is the problem of blindly applying a principle without understanding the problem it should solve. The result is mostly much worse then ignoring the principle.

  • Average SPA weight [on hold]

    - by Emmanuel Istace
    First, sorry my noobs questions, but I'm mainly Windows Developer and not Web Developer :) I'm developing a single page application with a lot of css & javascript. For now the page is 1.3Mo composed by 5 section. Here are the rounded stats : Document : 10kb Style : 60kb Images : 450 kb (already compressed, include a big gallery thumbnails) Javascript : 700kb - 600kb of "framework" (jquery, jquery-ui, boostrap, modernizer, waypoint, ...) and 100kb of custom js. Fonts : 125kb And the site is not finished yet. (Will include gmap api, and some others...) My questions are : Do you have any statistics about the average weight of an SPA ? As this is the whole website, do you think it's acceptable ? Is lazy load (for images) a solution ? What will be impact for SEO ? Is the "200kb rule" of google still relevant ? Do you know great tools to detect which javascript code is not used during the the exection of a page and then the availability to optimize these 700kb of framework js stuffs ? Can a caching strategy be an answer ? Thank you in advance for you help ! Best regards

  • iOS: Using Jenkins for nightly internal builds (TestFlight), plus frequent client builds

    - by Amy Worrall
    I'm an iOS dev, working for a small agency. I'm currently on a few smaller projects where I'm the only developer. We recently acquired a Jenkins server, but each project is left to fend for themselves as for how to use it. I'd like to use it for making and distributing builds. My ideal would be: Every commit is built as a single IPA that is placed in a HTTP-accessible location. (It only needs to keep the latest one, otherwise the disk would fill up — some of our apps are 500MB or more.) Once a day it makes a build, signs it with our internal provisioning profile, tacks a build number onto the end of the version number, and sends it to our internal TestFlight team. When manually prompted, it builds the latest commit, gives it a manually specified version number, signs it with the client's provisioning profile and sends it to TestFlight. I'm pretty new to Jenkins. The developer who set up the server is running it on one of our projects, so I know it has the right stuff installed to do Xcode builds. I believe he's only using it to run unit tests though, not to do any of the code signing, IPA creation or TestFlight stuff. So my questions: I've listed three distinct kinds of build. How does Jenkins cope with that? I see there's a "build triggers" section in the config for a Jenkins project, but it doesn't seem to mention different types of build. Should I just set up multiple Jenkins projects, called "App X (continuous)", "App X (nightly)" and "App X (client)"? How do I specify the provisioning profile through Jenkins? If there isn't a way, I guess I could make different configurations in the Xcode project… Has anyone else used Jenkins to actually do the release (i.e. build and push to TestFlight) of beta builds of their apps? Is it a good idea? Or should I continue just doing it manually?

  • Using Scrum on small projects where Owner doesn't want to be involved

    - by Andrej Mohar
    Recently I've been reading and learning quite a lot about scrum and I like it a lot. However, I do have a couple of likely scenarios in my head to which I don't know the solution. So let's say that I might want to organize an agile team of (for instance) four web developers (one of them UI/UX designer). This team would operate on scrum principles. Initially we would probably be working on projects like landing pages for ordinary people's small businesses, like renting apartments, selling cookies... Such customers simply can't be set with Product Owner role (IMHO), because they usually expect to hire a company, give them the overall project goal with some details, and then expect the job to be done (including a lot of decision making) with as little of their involvement as possible (in their opinion, they have more important things to do). Let's say I'd like to engage myself in a developer/scrum master role (I know that even that is debatable, being a team member and scrum master at once), so I simply shouldn't take the role of the product owner as well. So as for my questions: If I'm my company's business owner, do I simply need to be a product owner as well (do these roles include each other)? Can I employ a sales person which might have the product owner role? Would it be better if it is an experienced developer instead of a sales person? Is this even a smart move? Lastly, is there another agile approach that might better suit my position? EDIT: Thank you everyone for good inputs. I added some comments, any aditional info will be greatly appreciated.

  • Ajax application: using SOAP vs REST ?

    - by coder
    I'm building an ajax heavy application (client-side strictly html/css/js) which will be getting all the data and using server business logic via webservices. I know REST seems to be the hot topic but I can't find any good arguments. The main argument seems to be its "light-weight". My impression so far is that wsdl/soap based services are more expressive and allow for more a more complex transfer of data. It appears that soap would be more useful in the application I'm building where the only code consuming the services will be the js downloaded in the client browser. REST on the other hand seems to have a smaller entry barrier and so can be more useful for services like twitter in allowing other developers to consume these services easily. Also, REST seems to Te better suited for simple data transfers. So in summary SOAP is useful for complex data transfer and REST is useful in simple data transfer. I'm currently under the impression that using SOAP would be best due to the complexity of the messages but perhaps there's other factors. What are your thoughts on the pros/cons of soap/rest for a heavy ajax web app? EDIT: While the wsdl is in xml, the data I'm transferring back and forth is actually in JSON. It just appears more natural to use wsdl/soap here due to the nature of the app. The verbs GET and POST may not be enough. I may want to say something like: processQueue, or executeTimer. This is why my conclusion has been wsdl/soap would be good for bridging a complex layer between two applications (client and server) whereas REST would be better (due to its simplicity) for allowing many developer-users to consume resources programmatically. So you could say the choice falls along two lines Will the app be verb-oriented (completing tasks: use soap) or noun-oriented (consuming resources: use REST) Will the api be consumed by few developers or many developers (REST is strong for many developers)? Since such an ajax heavy app would potentially use many verbs and would only be used by the client developer it appears soap/wsdl would be the best fit.

  • Is my current employer expecting too much?

    - by priyank patel
    This is my first job as a programmer.I am working on ASP.NET/C#,HTML,CSS,Javascript/Jquery. I am working for a firm which develops software for small banking firms. Currently they have their software running in 100 firms.Their software is developed in Visual Fox Pro. I was hired to develop online version of this software.I am the solo developer. My boss is another developer.So my company has two developers. My boss doesnot have any idea about .NET development.I am working on their project since 8 months.The progress is surely there but not very big. I try my best to do what my boss asks.But the project just seems too ambitious for me. The company doesnot have any planning for the project.They just ask me to develop what their older software provides.So I have to deal with front end , back end,review codes , design architecture and etc. I have decided to give my best.I try a lot.But the project sometimes just seems to be overwhelming. So my questions is , is it normal for a programmer to be in this place. I always feel the need to work in atleast a small team if not big one. Are my employers just expecting too much of a fresher.Or is that I being a programmer am lacking the skills to deal with this. I am just not able judge my condition.Also I am paid very low salary.I do work on saturday as well. Can anyone just help me judge this scenario? Any suggestions are welcome.

  • Computer Science Degrees and Real-World Experience

    - by Steven Elliott Jr
    Recently, at a family reunion-type event I was asked by a high school student how important it is to get a computer science degree in order to get a job as a programmer in lieu of actual programming experience. The kid has been working with Python and the Blender project as he's into making games and the like; it sounds like he has some decent programming chops. Now, as someone that has gone through a computer science degree my initial response to this question is to say, "You absolutely MUST get a computer science degree in order to get a job as a programmer!" However, as I thought about this I was unsure as to whether my initial reaction was due in part to my own suffering as a CS student or because I feel that this is actually the case. Now, for me, I can say that I rarely use anything that I learned in college, in terms of the extremely hard math, algorithms, etc, etc. but I did come away with a decent attitude and the willingness to work through tough problems. I just don't know what to tell this kid; I feel like I should tell him to do the CS degree but I have hired so many programmers that majored in things like English, Philosophy, and other liberal arts-type degrees, even some that never went to college. In fact my best developer, falls into this latter category. He got started writing software for his church or something and then it took off into a passion. So, while I know this is one of those juicy potential down vote questions, I am just curious as to what everyone else thinks about this topic. Would you tell a high school kid about this? Perhaps if he/she already knows a good deal of programming and loves it he doesn't need a CS degree and could expand his horizons with a liberal arts degree. I know one of the creators of the Django web framework was a American Literature major and he is obviously a pretty gifted developer. Anyway, thanks for the consideration.

  • How do web-developers do web-design when freelancing?

    - by Gerald Blizz
    So I got my first job recently as junior web-developer. My company creates small/medium sites for wide variety of customers: autobusiness companies, weddign agencies, some sauna websites, etcetc, hope you get my point. They don't do big serious stuff like bank systems or really big systems, it's mostly small/medium-sized websites for startups/medium sized business. My main skills are PHP/MySQL, I also know HTML and a bit of CSS/JS/AJAX. I know that good web-developer must know some backend language (like PHP/Ruby/Python) AND HTML+CSS+JS+AJAX+JQuery combo. However, I was always wondering. In my company we have web-designer. In other serious organisations I often see the same stuff: web-developers who create business-logic and web-designers, who create design. As far as I know, after designers paint design of website they give it to developers either in PSD or sliced way, and developers put it together with logic, but design is NOT created by developers. Such separation seems very good for full-time job, but I am concerned with question how do freelance web-developers do websites? Do most of them just pay freelance designers to create design for them? Or do some people do both? Reason why I ask - I plan to start some freelancing in my free time after I get good at web-development. But I don't want to create websites with great business-logic but poor design. Neither I want to let someone else create a design for me. I like web-development very much and I am doing quite good, I like design aswell, even though I am a bit lost how to study it and get better at it. But I am scared that going in both directions won't let me become expert, it seems like two totally different jobs and getting really good in both seems very hard. But I really want to do both. What should I do? Thank you!

  • Part 3: Customization Strategy or how long does it take

    - by volker.eckardt(at)oracle.com
    The previous part in this blog should have made us aware, that many procedures are required to manage all these steps. To review your status let me ask you a question:What is your Customization Strategy?Your answer might be something like, 'customization strategy, well, we have standards and we let requirement documents approve'.Let me ask you another question:How long does it take to redeploy all your customizations into a fresh installation?In 90% of all installations the answer to this question would be: we can't!Although no one would have to do it (hopefully), just thinking about it and recognizing that we have today too many manual steps involved, different procedures and sometimes (undocumented) manual steps to complete a customization installation. And ... in general too many customizations.Why is working with customizations often so complicated and time consuming?Here are the key reasons as I have identified them in my projects:Customization standards defined, but not maintainedDifferent knowledge on developer side (results getting an individual developer touch)No need to automate deployment (not forced by client)Different documentation styles, not easy to hand over to someone elseDifferent development concepts, difficult for the maintenanceJust the minimum present for testing, often positive testing onlyDeviations from naming conventions accepted, although definedComplicated procedures, therefore sometimes partially ignoredAnd last but not least, hand made version control (still)If you would have to 'redeploy all your customizations' you would have to Follow all your own standards and best practiceTrack deviations and define corrective tasksAutomate as much as possible, minimize manual tasksDo not allow any change coming in without version controlUtilize products to support you in deploymentMinimize hand made scripts and extensive documentationReview regularly used techniques to guarantee that all are in line with the current release and also easy maintainableCreate solution libraries and force the team to contribute and reuseDefine quality activities and execute themDefine a procedure to release customizationsI know, it is easy to write down, but much harder to manage.
