• Groovy Refactoring in NetBeans

  - by Martin Janicek

  Hi guys, during the NetBeans 7.3 feature development, I spend quite a lot of time trying to get some basic Groovy refactoring to the game. I've implemented find usages and rename refactoring for some basic constructs (class types, fields, properties, variables and methods). It's certainly not perfect and it will definitely need a lot fixes and improvements to get it hundred percent reliable, but I need to start somehow :) I would like to ask all of you to test it as much as possible and file a new tickets to the cases where it doesn't work as expected (e.g. some occurrences which should be in usages isn't there etc.) ..it's really important for me because I don't have real Groovy project and thus I can test only some simple cases. I can promise, that with your help we can make it really useful for the next release. Also please be aware that the current version is focusing only on the .groovy files. That means it won't find any usages from the .java files (and the same applies for finding usages from java files - it won't find any groovy usages). I know it's not ideal, but as I said.. we have to start somehow and it wasn't possible to make it all-in-one, so only other option was to wait for the NetBeans 7.4. I'll focus on better Java-Groovy integration in the next release (not only in refactoring, but also in navigation, code completion etc.) BTW: I've created a new component with surprising name "Refactoring" in our bugzilla[1], so please put the reported issues into this category.

• Spotlight on GlassFish 4.1: #7 WebSocket Session Throttling and JMX Monitoring

  - by delabassee

  'Spotlight on GlassFish 4.1' is a series of posts that highlights specific enhancements of the upcoming GlassFish 4.1 release. It could be a new feature, a fix, a behavior change, a tip, etc. #7 WebSocket Session Throttling and JMX Monitoring GlassFish 4.1 embeds Tyrus 1.8.1 which is compliant with the Maintenance Release of JSR 356 ("WebSocket API 1.1"). This release also brings brings additional features to the WebSocket support in GlassFish. JMX Monitoring: Tyrus now exposes WebSocket metrics through JMX . In GF 4.1, the following message statistics are monitored for both sent and received messages: messages count messages count per second average message size smallest message size largest message size Those statistics are collected independently of the message type (global count) and per specific message type (text, binary and control message). In GF 4.1, Tyrus also monitors, and exposes through JMX, errors at the application and endpoint level. For more information, please check Tyrus JMX Monitoring Session Throttling To preserve resources on the server hosting websocket endpoints, Tyrus now offers ways to limit the number of open sessions. Those limits can be configured at different level: per whole application per endpoint per remote endpoint address (client IP address)   For more details, check Tyrus Session Throttling. The next entry will focus on Tyrus new clients-side features.

• Small-scale database options for .NET

  - by raney

  I have a .NET 4.0/WPF based application I've developed and maintain for my company that acts as a friendly GUI central-point-of-information, combining information pulled from a couple of SQL databases, as well as CSV exports from a few other applications. I would like to build out my own database to support the entirety of the information that the application accesses, so that I could have a service running on my server that would read in necessary remote SQL info and file exports, to provide the user's application with a single database to connect to, as well as to remove all of the file handling currently involved in the program (copying new CSV resources from network location, reading them into memory each launch.) I have complete control and flexibility here as long as the user's experience isn't affected, and this is as much a learning experience as it is tidying up. Caveat being, I don't have much in the way of a budget. Right now I recognize my options to be: SQL Express - I'm comfortable with the server setup, I like ADO.NET and LINQ to SQL. I feel that I have the least to learn here, but it would let me focus on SQL in a familiar environment. Perhaps in conjunction with Entity Framework? MongoDB - I don't know a whole lot about, but I've heard the name enough to make me curious. Brief research seems friendly enough, and there is .NET support. I like working with open source projects. My questions are: What's popular and extensible right now? I'm not far from starting to job-hunt, and I'd like this project to be relevant going forward. What am I missing? Pros, cons? Other options? What plays well with .NET? What are the things I should be considering, the questions I should be asking, when making a decision like this? Thanks for your time.

• What is the basic loadout for an open source web developer?

  - by DeveloperDon

  Thus far, I have mainly been an embedded developer, but I am interested in having the flexibility to do mobile and web development as well. I think my tools should include the following, but probably a lot more. LAMP stack. Java IDEs like Eclipse and IntelliJ. JS frameworks like Dojo, Node.JS, AngularJS, (is it better to mix or commit to one?). Cloud solutions like EC2 and Azure (again, ok to mix or better to commit to one?). Google APIs. Continuous integration server. Source control tools with Git for new work, SVN, CVS, +others for imports. FTP server. Unit test runners. Bug trackers. OOAD modeling tools or plug-ins? Graphic design tools? Hosting services. XML / JSON / other markup? Content management, SEO? I am also interested to know if there are tools where it might be better to mix, match, or support all available (maybe for source control) and others where the full focus should be on one (maybe Java vs. C# or Windows vs. Linux vs. MacOS). Perhaps some of these questions need context of whether the projects will be greenfield (just pick favorite) or maintenance (no choice, each project continues legacy, sometimes with a poor tools).

"To go beyond primitives, you must understand how these services should be used in a much larger architectural context. In other words, you need to understand how businesses will employ these services to form real workplace solutions -- inside and outside the enterprise."

• Open Source Projects for Beginning Coders?

  - by MattDMo

  After working as a molecular biologist at the bench for many years, I lost my job last year and am thinking about a career change. I've been using open-source software and doing Linux system administration since the mid 90s, and have written/improved some small shell/Perl/PHP scripts, and am very comfortable building from source, but never progressed to creating non-trivial programs de novo. I want to move to actually learning real programming skills and contributing back to the community, with the possible eventual goal of getting into bioinformatics as a career in the future. I'm a stay-at-home dad now, so I have some time on my hands. I've done a lot of research on languages, and have settled on Python as my major focus for now. I'm set up on GitHub, but haven't forked anything yet. I've looked around OpenHatch some, but nothing really grabbed me. I've heard the advice to work on what you use/love, but that category is so broad that I'm having trouble finding any one thing to get started on. What are your suggestions for getting started? How do you pick a project that will welcome your (possibly amateurish) help? With a fairly limited skill set, how do you find a request that you can handle? What are common newbie mistakes to avoid? Any other advice?

• Internet Explorer 9 is coming Monday to a web near you

  - by brian_ritchie

  Internet Explorer 9 is finally here...well almost.  Microsoft is releasing their new browser on March 14, 2011. IE9 has a number of improvements, including: Faster, Faster, Faster.  Did I mention it is faster?   With the new browsers coming out from Mozilla, Google, and Microsoft, there have been a flood of speed test coverage.  Chrome has long held the javascript speed crown.  But according to Steven J. Vaughan-Nichols over at ZDNET..."for the moment at least IE9 is actually the fastest browser I’ve tested to date."  He came to this revelation after figuring out that the 32-bit version of IE9 has the new Chakra JIT (the 64-bit version doesn't).  It also has a DirectX-based rendering engine so it can do cool tricks once reserved for desktop applications. Windows 7 Desktop Integration.  Read my post for more details.  Unfortantely, they didn't integrate my ideas...at least not yet :) Hot new UI.  Ok, they "borrowed" some ideas from Chrome...but that is the best form of flattery. Standards Compliance.  A real focus on HTML5 and CSS3.  Definite goodness for developers. So, go get yourself some IE9 on Monday and enjoy!

• UNESCO, J-ISIS, and the JavaFX 2.2 WebView

  - by Geertjan

  J-ISIS, which is the newly developed Java version of the UNESCO generalized information storage and retrieval system for bibliographic information, continues to be under heavy development and code refactoring in its open source repository. Read more about J-ISIS and its NetBeans Platform basis here. Soon a new version will be available for testing and it would be cool to see the application in action at that time. Currently, it looks as follows, though note that the menu bar is under development and many menus you see there will be replaced or removed soon: About one aspect of the application, the browser, which you can see above, Jean-Claude Dauphin, its project lead, wrote me the following: The DJ-Native Swing JWebBrowser has been a nice solution for getting a Java Web Browser for most popular platforms. But the Java integration has always produced from time to time some strange behavior (like losing the focus on the other components after clicking on the Browser window, overlapping of windows, etc.), most probably because of mixing heavyweight and lightweight components and also because of our incompetency in solving the issues. Thus, recently we changed for the JavaFX 2.2 WebWiew. The integration with Java is fine and we have got rid of all the DJ-Native Swing problems. However, we have lost some features which were given for free with the native browsers such as downloading resources in different formats and opening them in the right application. This is a pretty cool step forward, i.e., the JavaFX integration. It also confirms for me something I've heard other people saying too: the JavaFX WebView component is a perfect low threshold entry point for Swing developers feeling their way into the world of JavaFX.

• #altnetseattle - Kanban

  - by GeekAgilistMercenary

  The two main concepts of Kanban is to keep the queues minimum and to maintain visibility. Management/leadership needs to make sure the Kanban Queue doesn’t get starved.  This is key and also very challenging, being the queue needs to be minimal but also can’t get too small during the course of work.  This is to maintain maximum velocity. Phases of the Kanban need to be kept flowing too, bottlenecks need removed ASAP when brought up. Victory Wall – I dig that idea.  Somewhere to look to see the success of the team. The POs work in Rally or other tools for some client management, but it causes issues with the lack of "visibility" – a key fundamental ideal & part of Kanban. One of the big issues is fitting things into a sprint, when Kanban is used with Scrum, but longer sprints are wasteful. Kanban work sizes are of a set size. At this point I got a bit side tracked by the actual conversation and missed out on note taking.  Overall, people doing Kanban and Lean Style Software Development I would say are some of the happiest coders around.  The clean focus, good velocity, sizing, and other approaches that are inferred by Kanban help developers be the rock stars and succeed. This is definitely a topic I will be commenting on a lot more in the near future.

• Procedural content (settlement) generation

  - by instancedName

  I have, lets say, something like a homework or assignment to do. Roughly said I need to write an algorithm (pseudo code is not necessary, just in depth description) of procedure that would generate settlements, environment and a people to populate it with, as part of some larger world generation procedure. The genre of game is not specified, it could be any genre (rpg, strategy, colony simulation etc.) where interacting with large and extensive world is central to the game. Procedure should be called once per settlement. At the time of calling, world generation procedure makes geography, culture and history input available. Output should be map of the village and it's immediate area, and various potential additional information like myths, history, demographic facts etc. Bonus would be quest ant similar stuff, but that not really my focus at the moment. I will leave quality of the output for later when I actually dig little deeper into this topic. I am free to change parameters as long as I have strong explanation for doing so. Setting of the game is undetermined so I am free to use anything that I like the most. Ok, so my actual question is: Can anyone who has some experience in this field of game design recommend me some good literature, or point me in the direction where I should look/reed/study? I'm somewhat experienced game programmer, but I've never been into game design till now so any help will be great. I want to do this assignment as good as I can. As for deadline, it's not strictly set, but lets say I don't want it to take longer then few weeks, one month at worst case.

• Why don't windows of the same application behave as they should?

  - by Yuttadhammo

  Somewhere along the upgrade path, Unity has developed some strange logic behind window layering. First, before Oneiric, there was a way to see all the windows of an application - I think it was when you click on the icon in the launcher. Now, clicking on the icon often does nothing. Suppose I have two terminals open, one behind this Firefox window, and one in front of it. Clicking on the launcher does nothing - the only way to find the second terminal, afaics, is to move the Firefox window or use the task switcher. Secondly, once I have both terminals on top, then I decide to close one of them, suddenly they both disappear (the second one, for some reason, has gone into hiding behind the Firefox window). Third (though I can't pin it down now), sometimes when a window is on top, focus is still on a window in back; I click on the top x to close the window in front, only to find I've closed an important window in the back. (Update: this question details the problem) I can't really believe these are bugs, since they seem too obvious to not have been fixed by now. My question is, am I missing something? Some compiz option I can set to make it act like it used to? Or is this really how Unity is supposed to act?

• How can you achieve and maintain flow while pair programming?

  - by bizso09

  Flow is a concept introduced by Mihaly Csikszentmihalyi; in short, it means to get into the "zone". You feel immersed in your task, focused; the task can be difficult but challenging at the same time. When people achieve flow their productivity shoots up. Programming requires a great deal of mental focus because we often need to juggle several things in our minds at once. Many like to work in a quiet environment where they can direct their full attention to the task. If they are interrupted, it may take several minutes or even hours to get back into flow. I understand there's a practice in agile development and extreme programming called pair programming. It means you put the whole software development team in one room so that communication is seamless. You do write code with your pair because this way you get instant code reviews and fewer bugs get through. I've always had problems achieving flow while doing pair programming because of constant interruptions. I'm thinking deep about an issue then all of sudden someone asks me a question from another pair. My train of thought is lost. How can you achieve and maintain flow while pair programming?

• 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

• Learning good OOP design & unlearning some bad habits

  - by Nick

  I have been mostly a C programmer so far in my career with knowledge of C++. I rely on C++ mostly for the convenience STL provides and I hardly ever focus on good design practices. As I have started to look for a new job position, this bad habit of mine has come back to haunt me. During the interviews, I have been asked to design a problem (like chess, or some other scenario) using OOP and I doing really badly at that (I came to know this through feedback from one interview). I tried to google stuff and came up with so many opinions and related books that I don't know where to begin. I need a good through introduction to OOP design with which I can learn practical design, not just theory. Can you point me to any book which meets my requirements ? I prefer C++, but any other language is fine as long as I can pick-up good practices. Also, I know that books can only go so far. I would also appreciate any good practice project ideas that helped you learn and improve your OOP concepts. Thanks.

• Question on business connections and page rank?

  - by Viveta

  I just want to ask this question to get a yes no answer on something that I've been wondering on lately. So regarding how there are countless numbers of sites now that use the no-follow; making it harder to get ranking for your page if your website information might be something useful and will get traffic but maybe isn't something that your business connections share content of; but I am trying to find out if the benefit to having a bunch of say "likes" to your facebook page, but all the connection to your website's content isn't passing any benefit to your main page. So are you then competing with your own website in regards to SERPs to your facebook page and that of your home page. Am I correct on this; that if you start having your facebook page doing real good as far as connections and likes (helping bump up your facebook PageRank) but if you have links on your page with certain optimized keywords, that there is no benefit to your website (other than people getting to your facebook page, and then more likely to click to your page). Hope I explained it well what I am asking. Just wanted to get a better picture of this to know what I want to focus on as far as how I'll be linking to my desired landing pages in the future.

• Three New Videos on Social Development

  - by Bob Rhubart

  By now it should be clear to even the most tenacious Luddite that the social media phenomenon is no mere fad. Those ubiquitous icons for Facebook and Twitter and other social networks are little beacons of disruptive change signalling yet again that the 20th century is over, dude. And that presents an opportunity for software developers with the necessary insight and expertise to tap into and expand social platforms for forward-thinking organizations. If you're a developer and you're interested in exploiting these emerging opportunities you'll want to check out three new videos that focus on software development for social platforms. Developing with Facebook: An Introduction to Social Design James Pearce, Facebook's head of Mobile Developer Relations, provides an overview of the Facebook platform and the underlying APIs that are available to the developer community. Building on the LinkedIn Platform: Content Amplified Adam Trachtenberg, Director of LinkedIn's Developer Network, discusses how you can make it simple for a professional audience to discover and distribute your content on LinkedIn. Emergence of the Social Enterprise Roland Smart, Oracle's VP of Social Marketing, shares Oracle’s vision for the social-enabled enterprise and highlights the role developers will play in the next phase of enterprise development. OTN has also created the Oracle Social Developer Community, a new Facebook page devoted to the promotion of community conversation and resources to support Social Developers. If you're working on a social development project, visit the page and tell us about it.

• what languages are good selling points on resume? [closed]

  - by Thomas Galvin

  I have a good amount of experience with C# and Java at the moment but after education and whatnot I wish to be able in more than just 2 high-level, comparatively limited languages, and from what I've seen languages like C(++) or PHP are in demand at the moment. I've thought about learning the following: C. Very standard, lightweight and available on everything. However very old and mostly procedural. C++. Standard like C but I've read in some places that it encourages bad programming design and use of dodgy libraries - but similar things have been said about C too so I'll take that with a grain of salt. D. Quite new but looks promising, but will it be relevant or applicable in the future though? PHP. With the internet becoming ever more important I think this might be the one to go with, but the code itself isn't very intuitive. CoffeeScript (or plain JavaScript). With Microsoft's new idea of HTML5+JS for everything under the sun this doesn't look like a bad choice. However things do change and I wish to be primarily a software dev, not web dev. So out of the above list, or any others that you could suggest, what would you say I should begin to focus on? What is your opinion on staying with C#?

• How to document requirements for an API systematically?

  - by Heinrich

  I am currently working on a project, where I have to analyze the requirements of two given IT systems, that use cloud computing, for a Cloud API. In other words, I have to analyze what requirements these systems have for a Cloud API, such that they would be able to switch it, while being able to accomplish their current goals. Let me give you an example for some informal requirements of Project A: When starting virtual machines in the cloud through the API, it must be possible to specify the memory size, CPU type, operating system and a SSH key for the root user. It must be possible to monitor the inbound and outbound network traffic per hour per virtual machine. The API must support the assignment of public IPs to a virtual machine and the retrieval of the public IPs. ... In a later stage of the project I will analyze some Cloud Computing standards that standardize cloud APIs to find out where possible shortcomings in the current standards are. A finding could and will probably be, that a certain standard does not support monitoring resource usage and thus is not currently usable. I am currently trying to find a way to systematically write down and classify my requirements. I feel that the way I currently have them written down (like the three points above) is too informal. I have read in a couple of requirements enineering and software architecture books, but they all focus too much on details and implementation. I do really only care about the functionalities provided through the API/interface and I don't think UML diagrams etc. are the right choice for me. I think currently the requirements that I collected can be described as user stories, but is that already enough for a sophisticated requirements analysis? Probably I should go "one level deeper" ... Any advice/learning resources for me?

• How to prevent window list "confusion" when detaching eclipse views?

  - by amotzg

  I'm detaching eclipse views to float on my other screen in order to get more coding space on the first screen. When doing that, the detached windows appear in ubuntu's window list applet with the eclipse icon but with no title. Then, when pushing the main eclipse button on the window list, one of the detached views will get to front but not the main eclipse window. When using Alt+tab I can also see the extra eclipse icons but choosing the correct one for the main window works and make it the active window while also showing all detached childs. Other applications behave as expected, e.g. gimp floating panels don't show on the windows list and this is also the case with SlickEdit, Firefox child windows all show on window list but gets the focus correctly, etc. I can see the the workspace switcher show my two screens but in 'Monitor preferences' I see my two screens as one big screen. I'm working with ubuntu 10.04.4 under a VMware Workstation 7.1.3 build-324285. 'uname -a' output: Linux ubuntu 2.6.32-40-generic #87-Ubuntu SMP Tue Mar 6 00:56:56 UTC 2012 x86_64 GNU/Linux The desktop screen shot with the problem, ununtu's version, and Monitor preferences. How can I solve it and make only the main window show in window list or at least get activated when pushing it's button on the window list?

• Hello PCI Council, are you listening?

  - by David Dorf

  Mention "PCI" to any retailer and you'll instantly see them take a deep breath and start looking for the nearest exit.  Nobody wants to be insecure, but few actually believe that PCI does anything more than focus blame directly on retailers.  I applaud PCI for making retailers more aware of the importance of security, but did you have to make them PAINFULLY aware?  POS vendors aren't immune to this pain either as we have to undergo lengthy third-party audits in addition to the internal secure programming programs.  There's got to be a better way. There's a timely article over at StorefrontBacktalk that discusses the inequity of PCI's rules, and also mentions that the PCI Council is accepting comments until April 15th. As a vendor, my biggest issue with PCI is that they require vendors to disclose the details of any breaches, in effect "ratting out" customers.  I don't think its a vendor's place to do this.  I'd rather have the trust of my customers so we can jointly solve the problem. Mary Ann Davidson, Oracle's Chief Security Officer, has an interesting blog posting on this very topic.  Its a bit of a long read, but I found it very entertaining and thought-provoking.  Here's an excerpt: ...heading up the list of “you must be joking” regulations are recent disturbing developments in the Payment Card Industry (PCI) world. I’d like to give [the] PCI kahunas the benefit of the doubt about their intentions, except that efforts by Oracle among others to make them aware of “unfortunate side effects of your requirements” – which is as tactful I can be for reasons that I believe will become obvious below - have gone, to-date, unanswered and more importantly, unchanged. I encourage you to read the entire posting, Pain Comes Instantly, and then provide feedback to the PCI Council.

• Displaying a Grid of Data in ASP.NET MVC

  One of the most common tasks we face as a web developers is displaying data in a grid. In its simplest incarnation, a grid merely displays information about a set of records - the orders placed by a particular customer, perhaps; however, most grids offer features like sorting, paging, and filtering to present the data in a more useful and readable manner. In ASP.NET WebForms the GridView control offers a quick and easy way to display a set of records in a grid, and offers features like sorting, paging, editing, and deleting with just a little extra work. On page load, the GridView automatically renders as an HTML <table> element, freeing you from having to write any markup and letting you focus instead on retrieving and binding the data to display to the GridView. In an ASP.NET MVC application, however, developers are on the hook for generating the markup rendered by each view. This task can be a bit daunting for developers new to ASP.NET MVC, especially those who have a background in WebForms. This is the first in a series of articles that explore how to display grids in an ASP.NET MVC application. This installment starts with a walk through of creating the ASP.NET MVC application and data access code used throughout this series. Next, it shows how to display a set of records in a simple grid. Future installments examine how to create richer grids that include sorting, paging, filtering, and client-side enhancements. We'll also look at pre-built grid solutions, like the Grid component in the MvcContrib project and JavaScript-based grids like jqGrid. But first things first - let's create an ASP.NET MVC application and see how to display database records in a web page. Read on to learn more! Read More >

• Synaptics touchpad problem when disabling it and then enabling it

  - by CYREX

  My girlfriend has an HP dv6000. In ubuntu 10.10 32bit i use the synaptic on it and all is good but when i disable it and enable it the problem starts. when i press the disable button in the synaptics touchpad it disables the mouse AND the keyboard. After enabled the Keyboard keys and Mouse clicks do not work. If i click on the panel below, for example the Applications, Places or System buttons the focus gets stuck there forever. I can open nautilus by clicking on it but i can not use the menus, the ALT+F2 function, see the wireless connections, lower the sound through the panel, etc.. Here comes the weird part. If i press CTRL+ALT+F1 (or any other tty for that matter) and then come back to CTRL+ALT+F7 where the gui is everything works perfect again. This started about a week ago but she told me right now. i checked dmesg which is for sometime now throwing some warnings about Skipping EDID probe do to cached edid but for what i could find out this did not create the problem in the start. NOTE: I do not need to login when i do CTRL+ALT+F1 i just need to change to another tty then come back to F7. What could be causing this problem?
