  • Adopting Technologies for the Sake of Technologies

    - by shiju
    Unlike other engineering industries, the software engineering industry is really lacking maturity. The lack of maturity can see in different aspects of entire software development life cycle. I think other engineering industries are well organised and structured with common, proven engineering practices. The software engineering industry is greatly a diverse industry with different operating systems, and variety of development platforms, programming languages, frameworks and tools. Now these days, people are going behind the hypes and intellectual thoughts without understanding their core business problems and adopting technologies and practices for the sake of technologies and practices and simply becoming a “poster child” of technologies and practices. Understanding the core business problem and providing best, solid solution with a platform neutral approach, will give you more business values and ROI, instead of blindly adopting technologies and tailor-made your applications for the sake of technologies and practices. People have been simply migrating their solutions in favour of new technologies and different versions of frameworks without any business need. The “Pepsi Challenge” in the Software Development  Pepsi Challenge marketing campaign of the 1980s was a popular and very interesting marketing promotion in which people taste one cup of Pepsi and another cup with Coca Cola. In the taste test, more than 50% of people were preferred Pepsi  over Coca Cola. The success story behind the Pepsi was more sweetness contains in the Pepsi cola. They have simply added more sugar and more people preferred more sweet flavour. You can’t simply identify the better one after sipping one cup of cola based on the sweetness which contains. These things have been happening in the software industry for choosing development frameworks and technologies. People have been simply choosing frameworks based on the initial sugary feeling without understanding its core strengths and weakness. The sugary framework might be more harmful when you develop real-world systems. There is not any silver bullet for solving all kind of problems and frameworks and tools do have strengths and weakness. So it would be better to understand their strength and weakness. And please keep in mind that you have to develop real apps to understand the real capabilities and weakness of a framework. Evaluating a technology based on few blog posts will harm your projects and these bloggers might be lacking real-world experience with the framework. The Problem with Align a Development Practice with Tools Recently I have observed a discussion in a group where one guy asked suggestions for practicing Continuous Delivery (CD) as part of the agile based application engineering. Then the discussion quickly went to using and choosing a Continuous Integration (CI) tool and different people suggested different Continuous Integration (CI) tools for simply practicing Continuous Delivery. If you have worked with core agile engineering practices, you could clearly know that the real essence of agile is neither choosing a tool nor choosing a process. By simply choosing CI tool from a particular vendor will not ensure that you are delivering an evolving software based on customer feedback. You have to understand the real essence of a engineering practice and choose a right tool for practicing it instead of simply focus on a particular tool for a practicing an development practice. If you want to adopt a practice, you need a solid understanding on it with its real essence where tools are just helping us for better automation. Adopting New Technologies for the Sake of Technologies The another problem is that developers have been a tendency to adopt new technologies and simply migrating their existing apps to new technologies. It is okay if your existing system is having problem  with a technology stack or or maintainability challenge with existing solution, and moving to new technology for solving the current problems. We have been adopting new technologies for solving new challenges like solving the scalability challenges when the application or user bases is growing unpredictably. Please keep in mind that all new technologies will become old after working with it for few years. The below Facebook status update of Janakiraman, expresses the attitude of a typical customer. For an example, Node.js is becoming a hottest buzzword in the software industry and many developers are trying to adopt Node.js for their apps. The important thing is that Node.js is a minimalist framework that does some great things for some problems, but it’s not a silver bullet. I have been also working with Node.js which is good for some problems, but really bad for choosing it for all kind of problems. By adopting new technologies for new projects is good if we could get real business values from it because newer framework would solve some existing well known problems and provide better solutions where it can incorporate good solutions for the latest challenges . But adopting a new technology for the sake of new technology is really bad idea. Another example is JavaScript is getting lot of attention so that lot of developers are developing heavy JavaScript centric web apps. First, they will adopt a client-side JavaScript MV* framework from AngularJS, Ember, Backbone etc, and develop a Single Page App(SPA) where they are repeating the mistakes we did in the past with server-side. The mistakes we did in the server-side is transforming to client-side. The problem is that people are just adopting new technologies, but not improving their solutions. I predict that many Single Page App will suck in the future. We need a hybrid approach where we should be able to leverage both server-side and client-side for developing next-generation web apps. The another problem is that if you like a particular framework, use it for all kind of apps. In the past, I know some Silverlight passionate guys were tried to use that framework for all kind of apps including larger line of business apps. And these days developers are migrating their existing Silverlight apps in favour of HTML5 buzzword. So the real question is, what is the business values we are getting from these apps when we are developing it for the sake of a particular technology instead of business need. The another problem is that our solutions consultants are trying to provide unnecessary solutions for the sake of a particular technology or for a hype. For an example, Big Data solutions are great for solving the problem of three Vs : volume, velocity and variety. But trying to put this for every application will make problems. Let’s say, there is a small web site running with limited budget and saying that we need a recommendation engine for the web site with a Hadoop based solution with a 16 node cluster, would be really horrible. If we really need a Hadoop based solution, got for it, but trying to put this for all application would be a big disaster. It would be great if could understand the core business problems first, and later choose a right framework for providing solutions for the actual business problem, instead of trying to provide so many solutions. The Problem with Tied Up to a Platform Vendor Some organizations and teams are tied up with a particular platform vendor where they don’t want to use any product other than their preferred or existing platform vendor. They will accept any product provided by the vendor regardless of its capability. This will lets you some benefits regards with integration and collaboration of different products provided by the same vendor, but it will loose your opportunity to provide better solution for your business problems. For a real world sample scenario, lot of companies have been using SAP for their ERP solutions. When they are thinking about mobility or thinking about developing hybrid mobile apps, they can easily find out a framework from SAP. SAP provides a framework for HTML 5 based UI development named SAPUI5. If you are simply adopting that framework only based for the preference of existing platform vendor, you might be loose different opportunities for providing better solution. Initially you might enjoy the sugary feeling provided by the platform vendor, but you have to think about developing apps which should be capable for solving future challenges. I am not saying that any framework is not good and I believe that all frameworks are good over another one for solving at least one problem. My point is that we should not tied up with any specific platform vendor unless your organization is having resource availability problems. Being Polyglot for Providing Right Solutions The modern software engineering industry is greatly diverse with different tools and platforms. Lot of open source frameworks and new programming languages have been releasing to the developer community, where choosing the right platform without any biased opinion, is really a difficult task. But it would really great if we could develop an attitude with platform neutral mindset and being a polyglot developer for providing better solutions based on the actual business problems. IMHO, we should learn a new programming language and a new framework every year. This will improve the quality of our developer capabilities and also improve the quality of our primary programming language skills. Being polyglot for individual developers and organizational teams will give you greater opportunity to your developer experience and also for your applications. Organizations can analyse their business problem without tied with any technology and later they can provide solutions by choosing different platform and tools. Summary    In this blog post, what I was trying to say that we should not tied up or biased with any development platform, technology, vendor or programming language and we should not adopt technologies and practices for the sake of technologies. If we are adopting a technology or a practice for the sake of it, we are simply becoming a “poster child” of the technology and practice. We should not become a poster child of other people’s intellectual thoughts and theories, instead of it we should become solutions developers and solutions consultants where we should be able to provide better solutions for the business problems. Being a polyglot developer is a good idea for improving your developer skills which lets you provide better solutions for the business problems. The most important thing is that we should become platform neutral developers where our passion should be for providing brilliant solutions. It would be great if we could provide minimalist, pragmatic business solutions. You can follow me on Twitter @shijucv

  • How to keep word document, html and pdf documentation aligned

    - by dendini
    Is there a way to write documentation in a WYSIWYG editor which can then export into HTML, WORD and PDF and keep copies synchronized? This documentation are mostly technical notes and some contextual help for some softwares so they must contain images and some styling, they are not programmer's documentation (API list or functions list) for which probably a program like Javadoc or Doxygen would be the best choice. For example how do companies with hundreds different software lines and thousands of programmers deal with this? I have several solutions but they all seem lacking in some aspect: Latex/Tex : very good pdf and html export, not very user friendly and no full-blown WYSIWYG editor available. LibreOffice/OpenOffice : full blown WYSIWYG editor however html export not so good (need to edit manually exported html which needs to be maintained separately ) Mediawiki or any other wiki : could be keeping documentation in wikitext format, so html is automatically generated, pdf exportation is quite good with many available plugins. Again however need some formation for the staff to use it and need to setup a server for this. Notice I'm not asking for software A vs software B, I'm asking for general advice, big companies procedures for documentation and yes some software product names if available.

  • On the frontier between work and home

    - by MPelletier
    I think we've all been there: You hear of someone say "hey, wouldn't it be nice if platform X had feature Y?" You look around (on SO!), the feature really doesn't exist, even though it probably would be useful in many contexts. So it's pretty generic. Your mind wanders for a bit. "How tough would it be? Well, it'd probably be just a snippet. And an ad-hoc function. And maybe a wrapper." And boom, before you know it, you've spent a dozen hours of your free time implementing a FooFeature that's really neat and generic. The kind of code you might not even have the time to spit and shine at work, that would be a bit rushed and not so documented. So now you wonder "wouldn't this be useful to others?" And you've got your blog, maybe a CodeProject account, and your colleague who asked if FooFeature exists might, haphazardly, come accross that blog entry, had it existed before they told you. On the otherhand, the NDA agreement. It's sort of vague and general. It doesn't forbid you from coding at home, but it's clear on sharing company code, that's a big NO. But this isn't company code. Or is it? Or will it be? So, what do you do with code (that's more than just a snippet) you wrote in your off time with universality in mind but an idea that came from work, and that will most likely be used at work? Can it be published?

  • The Mystery of the Vanishing Disk Space

    - by Oddthinking
    My disk space is dwindling by about 2GB a day! I only have a few more days before I run out of space. $ df -h Filesystem Size Used Avail Use% Mounted on /dev/sda4 143G 126G 11G 93% / udev 491M 4.0K 491M 1% /dev tmpfs 200M 696K 199M 1% /run none 5.0M 0 5.0M 0% /run/lock none 499M 144K 499M 1% /run/shm /dev/sda2 1.9G 580M 1.2G 33% /tmp /dev/sda1 92M 29M 58M 33% /boot I have been searching for the biggest directories/log files, deleting and compressing. But I am still losing the war. Finally, I realised I have a big misunderstanding: julian@server1:~$ sudo du -h / | tail -n 1 16G / All of my files in / only add up to 16 GB. That leaves 110 GB unaccounted for! Clearly I have a misunderstanding: I thought the '/dev/sda4' line represented all the files visible from '/'. What should I be reading to understand where the other storage has gone? More details: I have an Ubuntu 11.10 server, that was set-up by data-center staff. It is running my own code (which is fairly prolific with log files, but otherwise doesn't store much stuff on the drive) duplicity for backups (which tends to store a lot of signature files) various other standard services, like Apache, nagios, etc. They are very lightly used. It has been up for about 4 months without a reboot. I lied about the du output (simplified it for effect). It also complained about not being able to access GVFS and the du processes's own resources. I believe they are irrelevant: . du: cannot access `/home/julian/.gvfs': Permission denied du: cannot access `/proc/10841/task/10841/fd/4': No such file or directory du: cannot access `/proc/10841/task/10841/fdinfo/4': No such file or directory du: cannot access `/proc/10841/fd/4': No such file or directory du: cannot access `/proc/10841/fdinfo/4': No such file or directory

  • ASP.NET MVC: Moving code from controller action to service layer

    - by DigiMortal
    I fixed one controller action in my application that doesn’t seemed good enough for me. It wasn’t big move I did but worth to show to beginners how nice code you can write when using correct layering in your application. As an example I use code from my posting ASP.NET MVC: How to implement invitation codes support. Problematic controller action Although my controller action works well I don’t like how it looks. It is too much for controller action in my opinion. [HttpPost] public ActionResult GetAccess(string accessCode) {     if(string.IsNullOrEmpty(accessCode.Trim()))     {         ModelState.AddModelError("accessCode", "Insert invitation code!");         return View();     }       Guid accessGuid;       try     {         accessGuid = Guid.Parse(accessCode);     }     catch     {         ModelState.AddModelError("accessCode", "Incorrect format of invitation code!");         return View();                    }       using(var ctx = new EventsEntities())     {         var user = ctx.GetNewUserByAccessCode(accessGuid);         if(user == null)         {             ModelState.AddModelError("accessCode", "Cannot find account with given invitation code!");             return View();         }           user.UserToken = User.Identity.GetUserToken();         ctx.SaveChanges();     }       Session["UserId"] = accessGuid;       return Redirect("~/admin"); } Looking at this code my first idea is that all this access code stuff must be located somewhere else. We have working functionality in wrong place and we should do something about it. Service layer I add layers to my application very carefully because I don’t like to use hand grenade to kill a fly. When I see real need for some layer and it doesn’t add too much complexity I will add new layer. Right now it is good time to add service layer to my small application. After that it is time to move code to service layer and inject service class to controller. public interface IUserService {     bool ClaimAccessCode(string accessCode, string userToken,                          out string errorMessage);       // Other methods of user service } I need this interface when writing unit tests because I need fake service that doesn’t communicate with database and other external sources. public class UserService : IUserService {     private readonly IDataContext _context;       public UserService(IDataContext context)     {         _context = context;     }       public bool ClaimAccessCode(string accessCode, string userToken, out string errorMessage)     {         if (string.IsNullOrEmpty(accessCode.Trim()))         {             errorMessage = "Insert invitation code!";             return false;         }           Guid accessGuid;         if (!Guid.TryParse(accessCode, out accessGuid))         {             errorMessage = "Incorrect format of invitation code!";             return false;         }           var user = _context.GetNewUserByAccessCode(accessGuid);         if (user == null)         {             errorMessage = "Cannot find account with given invitation code!";             return false;         }           user.UserToken = userToken;         _context.SaveChanges();           errorMessage = string.Empty;         return true;     } } Right now I used simple solution for errors and made access code claiming method to follow usual TrySomething() methods pattern. This way I can keep error messages and their retrieval away from controller and in controller I just mediate error message from service to view. Controller Now all the code is moved to service layer and we need also some modifications to controller code so it makes use of users service. I don’t show here DI/IoC details about how to give service instance to controller. GetAccess() action of controller looks like this right now. [HttpPost] public ActionResult GetAccess(string accessCode) {     var userToken = User.Identity.GetUserToken();     string errorMessage;       if (!_userService.ClaimAccessCode(accessCode, userToken,                                       out errorMessage))     {                       ModelState.AddModelError("accessCode", errorMessage);         return View();     }       Session["UserId"] = Guid.Parse(accessCode);     return Redirect("~/admin"); } It’s short and nice now and it deals with web site part of access code claiming. In the case of error user is shown access code claiming view with error message that ClaimAccessCode() method returns as output parameter. If everything goes fine then access code is reserved for current user and user is authenticated. Conclusion When controller action grows big you have to move code to layers it actually belongs. In this posting I showed you how I moved access code claiming functionality from controller action to user service class that belongs to service layer of my application. As the result I have controller action that coordinates the user interaction when going through access code claiming process. Controller communicates with service layer and gets information about how access code claiming succeeded.

  • How can we make agile enjoyable for developers that like to personally, independently own large chunks from start to finish

    - by Kris
    We’re roughly midway through our transition from waterfall to agile using scrum; we’ve changed from large teams in technology/discipline silos to smaller cross-functional teams. As expected, the change to agile doesn’t suit everyone. There are a handful of developers that are having a difficult time adjusting to agile. I really want to keep them engaged and challenged, and ultimately enjoying coming to work each day. These are smart, happy, motivated people that I respect on both a personal and a professional level. The basic issue is this: Some developers are primarily motivated by the joy of taking a piece of difficult work, thinking through a design, thinking through potential issues, then solving the problem piece by piece, with only minimal interaction with others, over an extended period of time. They generally complete work to a high level of quality and in a timely way; their work is maintainable and fits with the overall architecture. Transitioning to a cross-functional team that values interaction and shared responsibility for work, and delivery of working functionality within shorter intervals, the teams evolve such that the entire team knocks that difficult problem over. Many people find this to be a positive change; someone that loves to take a problem and own it independently from start to finish loses the opportunity for work like that. This is not an issue with people being open to change. Certainly we’ve seen a few people that don’t like change, but in the cases I’m concerned about, the individuals are good performers, genuinely open to change, they make an effort, they see how the rest of the team is changing and they want to fit in. It’s not a case of someone being difficult or obstructionist, or wanting to hoard the juiciest work. They just don’t find joy in work like they used to. I’m sure we can’t be the only place that hasn’t bumped up on this. How have others approached this? If you’re a developer that is motivated by personally owning a big chunk of work from end to end, and you’ve adjusted to a different way of working, what did it for you?

  • Changing Palette for Day/Light Mode using GIMP

    - by J.C.
    Hello, Suppose I've a picture, which want to achieve day/light mode by changing 8bpp color palette. If I want the pixel index of my picture is always fixed for both day mode and night mode. For example, the 1st pixel index is 100. Which I can look up index 100 in day mode palette and night mode palette. How can I use GIMP to do so? My goal is to not update my pixel index of my picture. Also, as you see in two palette, they are not one one mapping. That is index 1 of the day mode palette and index 1 of the night mode palette may not used in the same pixel of the picture, how can I tackle this problem? Actually, my use case is as follow I want to use one 8bpp picture to achieve day/night mode by update only the color palette (without updating the pixel index). The advantage is I only have to prepare 2 256 byte palette rather than saving 2 big pictures in my limited data ram. Thanks a lot

  • Web developing- Strange happenings

    - by Jason
    As I'm teaching myself PHP and MySQL during break, I'm experimenting coding in a Ubuntu virtual machine where Apache, MySQL and PHP have been installed and configured to a shared folder. I'm not a big fan of Kompozer because the source code layout is a PIA, so I've started checking out gPHPEdit. However, since using it, I've come across two issues: when I edit the .html and .php files, sometimes the file extension will change to .html~ and .php~, becoming invisible to the browser. The only solution is to switch to Windows, right click and rename the file extension. In Ubuntu Firefox, when I click on my prpject's Submit button for in a practice form, a dialog box pops up asking what Firefox should do with the .php file, rather than simply displaying it in the browser. When I do this in Windows Chrome & Firefox, it goes right to the response page. I'm not sure if this behavior is limited to gPHPEdit/Kompozer, but I've never noticed this happening in Dreamweaver. Any solutions? EDIT The behavior in Point 1 occurs both when Dreamweaver is open in Windows accessing the same files and when it is not. I changed the extension filename of welcome.php, added a comment in gPHPEdit, and the file changed to welcome.php~ upon saving.

  • Will HTML5/JS Eventually Replace All Client Side Languages? [closed]

    - by Shnitzel
    I'm just wondering about the future of it all. IMHO, there are 4 forces that define where technology goes: Microsoft, Apple, Google, Adobe. It looks like in Apple's iPhone/iPad iADs can now be programmed in HTML5. So does that mean HTML5 will eventually replace objective-c? Also, Microsoft has now shifted it's focus from WPF/Silverlight to HTML5 and I assume Visual Studio 2011 will be all about tooling support for HTML5. Because that's what Microsoft do. (Tools). In a few months IE9 the last major browser will support HTML5. Similarly Adobe is getting on the HTML5 bandwagon and allows to export flash content to HTML5 in their latest tools. And we all know how much in bed Google is with html5. Heck, their latest Operating System (Chrome OS) is nothing but a big fat web browser. Apps for Mobile (i.e., iPhone, Android, WM7) are very hard for a company to program especially for many different devices (each with their own language) so I'm assuming this won't last too long. I.e., HTML5 will be the unifying language. Which is somewhat sad for app developers because now users will be able to play the "cool" html5 apps for free on the web and it'll be hard to charge for them. So are strongly-typed languages really doomed, and in the future, say 5-10 years, will client side programming only be in HTML5? Will all of us become javascript programmers? :) Because the signs are sure pointing that way...

  • 24 Hours of PASS scheduling

    - by Rob Farley
    I have a new appreciation for Tom LaRock (@sqlrockstar), who is doing a tremendous job leading the organising committee for the 24 Hours of PASS event (Twitter: #24hop). We’ve just been going through the list of speakers and their preferences for time slots, and hopefully we’ve kept everyone fairly happy. All the submitted sessions (59 of them) were put up for a vote, and over a thousand of you picking your favourites. The top 28 sessions as voted were all included (24 sessions plus 4 reserves), and duplicates (when a single presenter had two sessions in the top 28) were swapped out for others. For example, both sessions submitted by Cindy Gross were in the top 28. These swaps were chosen by the committee to get a good balance of topics. Amazingly, some big names missed out, and even the top ten included some surprises. T-SQL, Indexes and Reporting featured well in the top ten, and in the end, the mix between BI, Dev and DBA ended up quite nicely too. The ten most voted-for sessions were (in order): Jennifer McCown - T-SQL Code Sins: The Worst Things We Do to Code and Why Michelle Ufford - Index Internals for Mere Mortals Audrey Hammonds - T-SQL Awesomeness: 3 Ways to Write Cool SQL Cindy Gross - SQL Server Performance Tools Jes Borland - Reporting Services 201: the Next Level Isabel de la Barra - SQL Server Performance Karen Lopez - Five Physical Database Design Blunders and How to Avoid Them Julie Smith - Cool Tricks to Pull From Your SSIS Hat Kim Tessereau - Indexes and Execution Plans Jen Stirrup - Dashboards Design and Practice using SSRS I think you’ll all agree this is shaping up to be an excellent event.

  • Java web app, with plugin framework and ability to connect to source for updates

    - by lessthancommon
    I've searched all around for some good sources, but either have been searching for the wrong keywords, or I'm just missing something. I'm looking to redevelop a web app I've been using for some time now. Many parts are out of date, and we're constantly throwing in little hacks to attempt to give it new life. So what I'd like to do is re-engineer it from the ground up, built on some sort of plug-in framework. Before I continue, I'm more or less an intermediate Java programmer. In some ways, I'm hoping to use this project as a big learning experience. I've read a lot about OSGi, and it seems that's the most complete framework. Ideally, I would like an end result web app which I can run one instance as my hosting environment, and other instances can connect to it to grab new and updated plug-ins. Eventually I'll want to lock down these plug-ins based on some undecided criteria of who can get them (basically some will simply be updates, others will provide new functionality and should be "purchased" through an external system). But that will probably be handled in a later phase. There should be an administration view for managing bundles in a hot environment (looking to avoid having to restart the server for an update). I know all these things are possible, I'm just trying to find some good resources for reference. All the OSGi tutorials I'm finding seem to be too simplistic. If anyone here can guide me in the right direction on any or all of the items I'm looking for, it would be much appreciated. Also, this is my first post, so I'll take any comments/criticisms about the content of my post. Thanks!

  • IoT? Time for Enterprise Architecture

    - by OTN ArchBeat
    Of course you've been listening to the latest OTN ArchBeat Podcast on the challenges and opportunities in the Internet of Things. If so, you'll also be interested in ZDNet blogger Joe McKendricks' recent post, Will the 'Internet of Things' make CIOs' jobs harder?. In that post McKendrick offers this important bit of advice that will certainly have architects saying "I told you so." Enterprises need to develop architectural approaches to the management of data. Meaning the development of repeatable processes to source, ingest, transform and store information. For years, IT managers simply bought more hardware and addressed data with on-off integration projects. Now it's time for enterprise architecture. IoT is an important new phase in the evolution of enterprise IT. Challenging? You bet! But meeting any such challenge requires big, broad thinking and planning. In that context Enterprise Architecture has always been important. But as IoT gains traction and speed, enterprise architecture should be top of mind for all concerned.

  • What are the licensing issues involved in the Oracle/Apache java dispute?

    - by Chris Knight
    I've just started following with interest the soap opera involving Oracle's acquisition of Java and the detriment of goodwill it seems to have generated in the open source community. Specifically, I'm now trying to get my head around the implications of Oracle's decision to refuse Apache an open source license for Harmony. My questions: 1) What is Harmony anyway? Their website states "Apache Harmony software is a modular Java runtime with class libraries and associated tools". How is this different than J2SE or J2EE? Or is Harmony akin to Andriod? 2) The crux of this issue is around the Java Technology Compatibility Kit (or TCK) which certifies that your implementation adheres to the JSR specifications. If I understand correctly, Oracle refuse to offer free or open source license access to the TCK, denying projects like Harmony from being released as open source. Why is this such a big deal for Apache? E.g. why can't (or don't) they release Harmony under a restricted license? 3) From this site is the following quote: It looks like Oracle’s plan is to restrict deployments of Java implementations in certain markets, particularly on mobile platforms, so that it can monetize its own Java offering in those markets without any competition. Presumably anything Oracle produced would be subject to the same restrictions it is imposing on others with respect to end-technology licensing, so how could they get a leg up on the competition? While no doubt distateful, wouldn't other competitors such as Google or Apache be able to release competing platforms under the same license as Oracle?

  • How to make the run button run the project, not the file, in Eclipse

    - by Roy T.
    I'm using the Spring IDE, a variant of Eclipse to create a Java project. One big irritation I have is that when I press the run button Eclipse tries to run the current file, which usually fails because it doesn't have a main method. I've set up run configurations in the hope that would make the play button default to the run configuration instead of the current file, but that doesn't work either. Now to run my application correctly I have to press the little arrow next to play, select my favorite run configuration and then it works, this is only two extra clicks but it's tedious, the button is small and I feel like I shouldn't have to perform these extra steps. I mean what is the point of run configurations and projects if it still tries to run a file by default? Even more preferably I wouldn't even want to touch the mouse but just press Ctrl+F11, but this has the same behavior. All above applies to debugging as well btw. So my question is this: how do I make the run and debug buttons (and their short keys) default to the project's run configuration instead of to trying (and failing) to run only the current file? Much like it is in Visual Studio and other IDEs?

  • What should I expect from a system engineer university career

    - by Trufa
    I'm starting tomorrow a series of interviews to decide which university should I choose to get a degree in System Engineer. I know this is a serious university but I would like to get some feedback about what should I expect or "demand" from the university. My experience in the technology field is (obviously) limited and would like to be aware of what should I to be aware if the university might be good or not. Specially in following fields: Infrastructure: what are the essentials? big pluses? Theoretical vs Practical: how practical should it be? what is a "good" mix? Programming languages, frameworks, etc: Which are the ideal for learning? Most demand? Latest technologies: What should they be teaching right know to "prove" they are up to date. Qualification system: What exam methods do you think are ideal for this kind of degree, good ol' Q&A, multiple choice, projects, a fair mix? What other points do you think I should care about? What isn't important? Thanks in advance. I realize this is might be a very subjective topic so I tried to make it as specific and on topic as I could but any recommendations are of course welcome. I also understand that none of this questions will guarantee this will be a good university but it might give me another reference as to which should I choose when the moment comes.

  • Almost at our first year anniversary!

    - by Vizioz Limited
    It has been a hectic first year at Vizioz and things are still going from strength to strength. 11 months ago I started Vizioz with zero capital investment in the middle of a recession, which to some may seem a daunting prospect but to others including myself it was the challenge I needed to make me want to get up in the morning :) I wanted to prove that even in the curent financial climate it is still possible to start a new business.We are still experiencing the normal growing pains of a small business but this is something we just need to work our way through, it is amazing how much paperwork and administration there is running a small business, office admin, insurance, vat and for the last few months PAYE.For the last 9 months we have shared an office with another small business called Little Big Ideas. They are a design agency working across a broad spectrum of design from branding, print and digital. Last month we decided to move offices to a larger office and now have room for 8 of us, so now we need a couple more clients to help produce enough work to fill the space and grow to the next level.As well as moving office 2 months ago I blogged about my first employee Colin starting work for me, he has picked up Umbraco very well and has mastered the art of good CSS design, as the majority of our clients are large multi-nationals they still require support for IE6 which as all web developers know is the nightmare of all web browsers.This month has seen the next step in the growth of Vizioz as I have taken on another PhD graduate called Pricilla, welcome to the team!This month we plan to launch our own website to enable us to showcase some of the sites we have built over the past 11 months and to allow potential clients to see what we can offer. We might still be relatively small but we have some great case studies to show and with two PhD graduates on the team we have great talent capable of producing complex and innovative solutions for our clients. As soon as we have launched out new website I will blog again about what the future holds for Vizioz and what we can offer our prospective clients as well as e obvious Umbraco CMS solutions.

  • How can we make agile enjoyable for developers that like to personally, independently own large chunks from start to finish

    - by Kris
    We’re roughly midway through our transition from waterfall to agile using scrum; we’ve changed from large teams in technology/discipline silos to smaller cross-functional teams. As expected, the change to agile doesn’t suit everyone. There are a handful of developers that are having a difficult time adjusting to agile. I really want to keep them engaged and challenged, and ultimately enjoying coming to work each day. These are smart, happy, motivated people that I respect on both a personal and a professional level. The basic issue is this: Some developers are primarily motivated by the joy of taking a piece of difficult work, thinking through a design, thinking through potential issues, then solving the problem piece by piece, with only minimal interaction with others, over an extended period of time. They generally complete work to a high level of quality and in a timely way; their work is maintainable and fits with the overall architecture. Transitioning to a cross-functional team that values interaction and shared responsibility for work, and delivery of working functionality within shorter intervals, the teams evolve such that the entire team knocks that difficult problem over. Many people find this to be a positive change; someone that loves to take a problem and own it independently from start to finish loses the opportunity for work like that. This is not an issue with people being open to change. Certainly we’ve seen a few people that don’t like change, but in the cases I’m concerned about, the individuals are good performers, genuinely open to change, they make an effort, they see how the rest of the team is changing and they want to fit in. It’s not a case of someone being difficult or obstructionist, or wanting to hoard the juiciest work. They just don’t find joy in work like they used to. I’m sure we can’t be the only place that hasn’t bumped up on this. How have others approached this? If you’re a developer that is motivated by personally owning a big chunk of work from end to end, and you’ve adjusted to a different way of working, what did it for you?

  • Podcast Show Notes: Old Habits Die Hard in the New SOA World

    - by OTN ArchBeat
    Like the previous series, the latest OTN ArchBeat Podcast program was also recorded in a hotel room just around the corner from Oracle OpenWorld in San Francisco just a few weeks ago. The gathered experts, all members of the OTN architect community, agreed to participate in an informal roundtable discussion of what's happening in Service Oriented Architecture. As you'll hear, the conversation ranged from the maturity of Service Oriented Architecture technology and tools, to the the lingering and typically self-imposed problems that can prevent organizations from realizing the full potential of SOA, to what SOA means in the era of *aaS, mobile computing, and big data. Hajo Normann, Torsten Winterberg, Ronald van Luttikhuizen, and Guido Schmutz (L-R) Hajo Normann, Torsten Winterberg, Danilo Schmeidel, and Lonneke Dikmans (L-R) The Panelists (Listed alphabetically) Lonneke Dikmans, Managing Partner at Vennster, Oracle ACE Director Ronald van Luttikuhuizen, Managing Partner at Vennster, Oracle ACE Director Hajo Normann, SOA & BPM Lead for ASG at Accenture, Oracle ACE Director Danilo Schmiedel, Solution Architect at Opitz Consulting Guido Schmutz, Technology Manager for SOA/BPM and Architecture Board at Trivadis, Oracle ACE Director Torsten Winterberg, Director of Strategy and Innnovation and head of SOA Competence Center at Opitz Consulting, Oracle ACE Director The Conversation Listen to Part 1: SOA technology and tools are mature, says this panel of experts, but why do some organizations still struggle to take full advantage of industrialized SOA? Listen to Part 2 (Nov 6): Human nature and a lack of trust among stakeholders can thwart successful SOA. Can a marketplace approach and social tools improve the situation? Listen to Part 3 (Nov 13): Do SOA stakeholders recognize the problems caused by poor communication among siloed service development teams? Coming Soon SOA and B2B: The authors of Getting Started with Oracle SOA B2B Integration: A Hands-On Tutorial discuss Business to Business capabilities in Oracle SOA Suite 11g.

  • How to Recover that Photo, Picture or File You Deleted Accidentally

    - by The Geek
    Have you ever accidentally deleted a photo on your camera, computer, USB drive, or anywhere else? What you might not know is that you can usually restore those pictures—even from your camera’s memory stick. Windows tries to prevent you from making a big mistake by providing the Recycle Bin, where deleted files hang around for a while—but unfortunately it doesn’t work for external USB drives, USB flash drives, memory sticks, or mapped drives. Luckily there’s another way to recover deleted files. Note: we originally wrote this article a year ago, but we’ve received this question so many times from readers, friends, and families that we’ve polished it up and are republishing it for everybody. So far, everybody has reported success!

  • Why does TDD work?

    - by CesarGon
    Test-driven development (TDD) is big these days. I often see it recommended as a solution for a wide range of problems here in Programmers SE and other venues. I wonder why it works. From an engineering point of view, it puzzles me for two reasons: The "write test + refactor till pass" approach looks incredibly anti-engineering. If civil engineers used that approach for bridge construction, or car designers for their cars, for example, they would be reshaping their bridges or cars at very high cost, and the result would be a patched-up mess with no well thought-out architecture. The "refactor till pass" guideline is often taken as a mandate to forget architectural design and do whatever is necessary to comply with the test; in other words, the test, rather than the user, sets the requirement. In this situation, how can we guarantee good "ilities" in the outcomes, i.e. a final result that is not only correct but also extensible, robust, easy to use, reliable, safe, secure, etc.? This is what architecture usually does. Testing cannot guarantee that a system works; it can only show that it doesn't. In other words, testing may show you that a system contains defects if it fails a test, but a system that passes all tests is not safer than a system that fails them. Test coverage, test quality and other factors are crucial here. The false safe feelings that an "all green" outcomes produces to many people has been reported in civil and aerospace industries as extremely dangerous, because it may be interepreted as "the system is fine", when it really means "the system is as good as our testing strategy". Often, the testing strategy is not checked. Or, who tests the tests? I would like to see answers containing reasons why TDD in software engineering is a good practice, and why the issues that I have explained above are not relevant (or not relevant enough) in the case of software. Thank you.

  • Which would be a better way to load data via ajax

    - by Mike
    I am using google maps and returning html/lat/long from my MySQL database Currently A user picks a business category e.g; "Video Production". an ajax call is sent to a CodeIgniter controller the Controller then queries the db, and returns the following data via JSON Lat/Long of the marker HTML for the popup window this is approximately 34 rows in the database across two tables per business the ajax call receives this data and then plots the marker along with the html onto the map The data that is returned from the controller is one big json object... This is done for all businesses that exist in the Video Production category (currently approx 40 businesses). As you can see, pulling this data for multiple categories (100s of businesses) can get very very taxing on the server. My question is Would it be more beneficial to modify the process flow as such: a user picks a business category e.g; "Video Production". an ajax call is sent to a CodeIgniter controller the controller then queries the database for the location base information lat/long level (used to change marker icon color) This would be a single row per business with several columns the ajax call receives this data and then plots the marker on the map when the user clicks a marker an ajax call is sent to a CodeIgniter Controller the controller queries the database for the HTML and additional data based on business_id and if not, what are some better suggestions to this problem? In summary this means rather than including the HTML and additional data along for each business, only submitting minimal location information and then re-query for that information when each business marker is clicked. Potential Downsides longer load times when a user clicks a marker icon more code?? more queries to the database
