  • TechEd Israel 2010 may only accept speakers from sponsors

    A month or so ago, Microsoft Israel started sending out emails to its partners and registered event users to Save the date! Micraoft Teched Israel is coming, and its going to be this november! Great news I thought to myself. Id been to a couple of the MS teched events, as a speaker and as an attendee, and it was lovely and professionally done. Israel is an amazing place for technology and development and TechEd hosted some big names in the world of MS software. A couple of weeks ago, I was shocked...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Should I use C style in C++?

    - by c.hughes
    As I've been developing my position on how software should be developed at the company I work for, I've come to a certain conclusion that I'm not entirely sure of. It seems to me that if you are programming in C++, you should not use C style anything if it can be helped and you don't absolutely need the performance improvement. This way people are kept from doing things like pointer arithmetic or creating resources with new without any RAII, etc. If this idea was enforced, seeing a char* would possibly be a thing of the past. I'm wondering if this is a conclusion others have made? Or am I being too puritanical about this?

  • How do I find funny pictures?

    - by Hanno Fietz
    No, not lolcats. And I'm not really looking for a specific site, either. I have often wished that I had some funny picture to illustrate a presentation, a website, a post, an email, or something else. Google image search and stock photo services have hardly ever helped me, although that may be because I'm doing something wrong. Jeff Atwood seems to have no problem to find funny pictures for his codinghorror and stackoverflow blogs, as well as for the error messages on the trilogy sites. One of my favourites was this elephant. Other bloggers also seem to be quite good at it. I'm wondering if I simply lack the creativity or if there's sources or methods I don't know about. I could think of the following ways to get pictures, but I'm not sure whether this is really "how they do it". keep a collection of pictures that you stumbled upon and liked (takes quite some time to build up to a proper library), when you need a picture, there's one in there maybe have pictures on paper, too, like from magazines or ads. when you are looking for a picture, search online (Flickr, Google, stock photos). This has never really worked for me, I don't know why. produce the pictures yourself, i. e. have a good library of source material or find some online and apply some creativity and suitable software. I could imagine that this could work well once you have the practice.

  • Laptops or Notebooks in a meeting? [closed]

    - by greengit
    Is taking the laptop to the meeting a good idea? Of course, the project leader needs to have one -- but the programmers -- especially those who only need to get straight instructions on what to do next on the project -- do they need to take laptops? I feel it takes longer to save notes in a software -- and it's lot easier to just jot down "things to do" in a simple note book. That way you can keep up with the discussion and not lose track of what someone else is saying by spending too much time entering text in the machine.

  • How to create VHD disk image from a Linux live system?

    - by Federico
    Once more, I have to resort at the experts here at SuperUser, as my other sources (mainly Google ;-)) didn't prove very helpful... So basically, I would like to create a VHD image of a physical disk to be archived/accessed/maybe even mounted in a virtual machine. Now, there are dozens of articles and tutorials on how to do that on the web, but none that meets exactly the conditions I would like to achieve: I would like the destination file to be a VHD image, as Windows 7 can mount it natively, even over the network and many other programs can use it (VirtualBox, ...) The disk I'm trying to image contains a Windows XP install, so in theory, I could use the disk2vhd utility, but I would like to find a solution that doesn't require booting that Windows XP install (ie keep the disk read-only) Thus I was searching for a solution involving some sort of live system (running from a USB stic or the network) However, all the solutions that I've came across either make use of disk2vhd or use the dd command under linux, which does a complete copy of the disk (ie even empty blocks) and does not output a VHD file. Is there a tool/program under Linux that can directly create a VHD file? Or is is possible to convert a raw disk image created using dd to a VHD file, without allocating space for the empty blocks? How would you proceed? As always, any advice or comment is highly appreciated!!

  • How can I become more agile?

    - by dough
    The definition of an agile approach I've adopted is: working to reduce feedback loops, everywhere. I'd describe my Personal Development Process (PDP) as "not very agile" or "not agile enough"! I've adopted TDD, automated building, and time-boxing (using the Pomodoro Technique) as part of my PDP. I find these practices really help me get feedback, review my direction, and catch yak shaving earlier! However, what still escapes me is the ability to reduce feedback time in the ultimate feedback loop; regularly getting working software in front of the end user. Aside from team-oriented practices, what can I do to personally become more agile?

  • Can a loosely typed language be considered true object oriented?

    - by user61852
    Can a loosely typed programming language like PHP be really considered object oriented? I mean, the methods don't have returning types and method parameters has no declared type either. Doesn't class design require methods to have a return type? Don't methods signatures have specifically-typed parameters? How can OOP techniques help you code in PHP if you always have to check the types of parameters received because the language doesn't enforce types? Please, if I'm wrong, explain it to me. When you design things using UML, then code classes in PHP with no return-typed methods and no-type parameters... Is the code really compliant with the UML design? You spend time designing the architecture of your software, then the compiler doesn't force the programmer to follow your design while coding, letting he/she assign any object variable to any other variable with no "type-mismatch" warning.

  • Installing sqlite gem fails on AWS Linux instance with sqlite-devel libraries installed

    - by Scott
    Hi, I'm running an instance built off ami-595a0a1c. I am trying to install the sqlite3 (or sqlite) gem and it's failing with the below error: $ sudo gem install sqlite3 Building native extensions. This could take a while... ERROR: Error installing sqlite3: ERROR: Failed to build gem native extension. /usr/bin/ruby extconf.rb checking for sqlite3.h... no sqlite3.h is missing. Try 'port install sqlite3 +universal' or 'yum install sqlite3-devel' and check your shared library search path (the location where your sqlite3 shared library is located). extconf.rb failed * Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers. Check the mkmf.log file for more details. You may need configuration options.

However, I have installed the sqlite-devel packages and still no dice. Since this is the Amazon Linux instance, I'd rather not add more repositories than the ones Amazon provides if possible. What can i do to get this thing to compile? Thanks for any insight! From a brand new instance, here's what I've done: $ sudo yum install rubygems ruby-devel $ sudo gem update --system $ sudo gem install rails $ rails new app $ cd app $ rails server Could not find gem 'sqlite3 (= 0)' in any of the gem sources listed in your Gemfile. $ sudo yum install sqlite-devel $ sudo gem install sqlite (or sqlite3 -- same result) See breakage above

  • Integrating application ad-support - best practice

    - by Jarede
    Considering the review that came out in March: Researchers from Purdue University in collaboration with Microsoft claim that third-party advertising in free smartphone apps can be responsible for as much as 65 percent to 75 percent of an app's energy consumption. Is there a best practice for integrating advert support into mobile applications, so as to not drain user battery too much. When you fire up Angry Birds on your Android phone, the researchers found that the core gaming component only consumes about 18 percent of total app energy. The biggest battery suck comes from the software powering third-party ads and analytics accounting for 45 percent of total app energy, according to the study. Has anyone invoked better ways of keeping away from the "3G Tail", as the report puts it. Is it better/possible to download a large set of adverts that are cached for a few hours, and using them to populate your ad space, to avoid constant use of the wifi/3g radios. Are there any best practices for the inclusion of adverts in mobile apps?

  • Java - learning / migrating fast

    - by Yippie-Kai-Yay
    This is not one of those questions like "How do I learn Java extremely fast, I know nothing about programming, but I heard Java is cool, yo". I have an interview for a Java Software Developer in a couple of weeks and the thing is that I think that I know C++ really good and I am somewhat good at C# (like, here I can probably answer on a lot of questions related to these languages), but I have almost zero experience with Java. I have a lot of projects written in both languages, I participiated in several open-source projects (mostly C++, though). Now, what should I do (in your opinion) to prepare myself for this Java interview. I guess migrating from C# to Java should be kind of fast, especially when you know a lot about programming in global, patterns, modern techniques and have a lot of practical experience behind you. But still two weeks is obviously not enough to get Java in-depth - so what should I focus on to have the best chances to pass the interview? Thank you.

  • How to introduce versioning for questions on Stack*? [closed]

    - by András Szepesházi
    What today is the best answer for any given question, yesterday was not available and tomorrow will be obsolete. Especially when we're talking about software development. Here is an example for you (there must be thousands, this one is absolutely imaginary): Q: What is the best way to implement autocomplete in javascript? A: (2000) Whut? A: (2007) Write a custom ajax function, display the results after processing A: (2011) Use this plugin: http://jqueryui.com/demos/autocomplete/ (nono, I'm not a jQuery affiliate, actually I prefer MooTools) What would be your recommendation to introduce versioning for Stack Exchange questions and answers? Is there a need at all for that?

  • What resources will help me understand the data model for QC 10.0 in order to write my SQL queries?

    - by srihari
    I am a fresher in Quality Center 10.0 HP software testing tool. As per my understanding in order to generate reports from QC and to troubleshoot the scenarios, we need to write SQL queries in the QC back end database. In my case it is SQL db. I downloaded the database reference help file but I could not understand from where I can start. It just gave the table name and its information. For a starter like me are there any online tutorials or helpful websites,hands on exercises,scenario's where I can better understand how to write queries for the QC data model? I am very confident about the SQL coding itself, what I want to know is how to query on the QC database tables based on the scenarios that occur in QC tool. Please suggest. Thanks, Srihari

  • Testing on Device Other Than the Known Brand Question (Local and Imported Phone Question)

    - by David Dimalanta
    I have a question. When testing a device by using Eclipse, it's easy to install and add device software with these specific brands commonly used in game testing like Samsung, Google, T-Mobile, and HTC; according to the Android Developers website. What if I'm using other brands that runs on Android to test the program via Eclipse (i.e. MyPhone, Starmobile), what should I look for to download in order to enable testing phones that those brands are using other than the brands that are known and commonly used: model number or simply brand? Here's some examples of these brands other than the brands we've known that runs on Android: Starmobile Engage 7 (http://www.lazada.com.ph/Starmobile-Engage-7-Android-40-4GB-with-Wi-Fi-Black-Starmobile-Mercury-B201-COMBO-39833.html/) My|Phone A898 Duo (http://www.myphone.com.ph/#!a898-duo/c1yt) Also, take note that I'm a Filipino programmer working at the Philippines to test our local smartphones for the created Android game or app. Hope you can understand me for my help.

  • Better Programming By Programming Better?

    - by ahmed
    I am not convinced by the idea that developers are either born with it or they are not. Where’s the empirical evidence to support these types of claims? Can a programmer move from say the 50th to 90th percentile? However, most developers are not in the 99th or even 90th percentile (by definition), and thus still have room for improvement in programming ability, along with the important skills.The belief in innate talent is “lacking in hard evidence to substantiate it” as well.So how do I reconcile these seemingly contradictory statements? I think the lesson for software developers who wish to keep on top of their game and become experts is to keep exercising the mind via effortful studying. I read a lot technical books, but many of them aren’t making me better as a developer.

  • OpenJDK DIO Project Now Live! Java SE Embedded API Accessing Peripherals

    - by hinkmond
    The DIO project on OpenJDK is now live! For those who grew up in the 1970's and 1980's, you might remember Ronnie James Dio, lead singer of Black Sabbath after Ozzy was fired, and lead singer of his own band, Dio. Well, this DIO is not that Dio. This DIO is the OpenJDK Device I/O project which provides a Java-level API for accessing generic device peripherals on embedded devices, like your Raspberry Pi running Java SE Embedded software. See: OpenJDK DIO Project Here's a quote: + General Purpose Input/Output (GPIO) + Inter-Integrated Circuit Bus (I2C) + Universal Asynchronous Receiver/Transmitter (UART) + Serial Peripheral Interface If you're familiar with Pi4J, then you're going to like DIO. And, if you liked Ozzy, you probably liked Ronnie James Dio. This will probably make Robert Savage happy too. The part about DIO being live now, not the part about Dio replacing Ozzy, because everyone likes Ozzy. Hinkmond

  • How to document/verify consistent layering?

    - by Morten
    I have recently moved to the dark side: I am now a CUSTOMER of software development -- mainly websites. With this new role comes new concerns. As a programmer i know how solid an application becomes when it is properly layered, and I want to use this knowledge in my new job. I don't want business logic in my presentation layer, and certainly not presentation stuff in my data layer. Thus, I want to be able to demand from my supllier that they document the level of layering, and how neat and consistent the layering is. The big question is: How is the level of layering documented to me as a customer, and is that a reasonable demmand for me to have, so I don't have to look in the code (I'm not supposed to do that anymore)?

  • Delving into design patterns, and what that means for the Oracle user experience

    - by Kathy.Miedema
    By Kathy Miedema, Oracle Applications User Experience George Hackman, Senior Director, Applications User Experiences The Oracle Applications User Experience team has some exciting things happening around Fusion Applications design patterns. Because we’re hoping to have some new offerings soon (stay tuned with VoX to see what’s in the pipeline around Fusion Applications design patterns), now is a good time to talk more about what design patterns can do for the individual user as well as the entire company. George Hackman, Senior Director of Operations User Experience, says the first thing to note is that user experience is not just about the user interface. It’s about understanding how people do things, observing them, and then finding the patterns that emerge. The Applications UX team develops those patterns and then builds them into Oracle applications. What emerges, Hackman says, is a consistent, efficient user experience that promotes a productive workplace. Creating design patterns What is a design pattern in the context of enterprise software? “Every day, people use technology to get things done,” Hackman says. “They navigate a virtual world that reaches from enterprise to consumer apps, and from desktop to mobile. This virtual world is constantly under construction. New areas are being developed and old areas are being redone. As this world is being built and remodeled, efficient pathways and practices emerge. “Oracle's user experience team watches users navigate this world. We measure their productivity and ask them about their satisfaction. We take the most efficient, most productive pathways from the enterprise and consumer world and turn them into Oracle's user experience patterns.” Hackman describes the process as combining all of the best practices from every part of a user’s world. Members of the user experience team observe, analyze, design, prototype, and measure each work task to find the best possible pattern for a particular work flow. As the team builds the patterns, “we make sure they are fully buildable using Oracle technology,” Hackman said. “So customers know they can use these patterns. There’s no need to make something up from scratch, not knowing whether you can even build it.” Hackman says that creating something on a computer is a good example of a user experience pattern. “People are creating things all the time,” he says. “On the consumer side, they are creating documents. On the enterprise side, they are creating expense reports. On a mobile phone, they are creating contacts. They are using different apps like iPhone or Facebook or Gmail or Oracle software, all doing this creation process.” The Applications UX team starts their process by observing how people might create something. “We observe people creating things. We see the patterns, we analyze and document, then we apply them to our products. It might be different from phone to web browser, but we have these design patterns that create a consistent experience across platforms, and across products, too. The result for customers Oracle constantly improves its part of the virtual world, Hackman said. New products are created and existing products are upgraded. Because Oracle builds user experience design patterns, Oracle's virtual world becomes both more powerful and more familiar at the same time. Because of design patterns, users can navigate with ease as they embrace the latest technology – because it behaves the way they expect it to. This means less training and faster adoption for individual users, and more productivity for the business as a whole. Hackman said Oracle gives customers and partners access to design patterns so that they can build in the virtual world using the same best practices. Customers and partners can extend applications with a user experience that is comfortable and familiar to their users. For businesses that are integrating different Oracle applications, design patterns are key. The user experience created in E-Business Suite should be similar to the user experience in Fusion Applications, Hackman said. If a user is transitioning from one application to the other, it shouldn’t be difficult for them to do their work. With design patterns, it isn’t. “Oracle user experience patterns are the building blocks for the virtual world that ensure productivity, consistency and user satisfaction,” Hackman said. “They are built for the enterprise, but incorporate the best practices from across the virtual world. They empower productivity and facilitate social interaction. When you build with patterns, you get all the end-user benefits of less training / retraining from the finished product. You also get faster / cheaper development.” What’s coming? You can already access design patterns to help you build Dashboards with OBIEE here. And we promised you at the beginning that we had something in the pipeline on Fusion Applications design patterns. Look for the announcement about when they are available here on VoX.

  • OracleWebLogic YouTube Channel

    - by Jeffrey West
    James Bayer and I have been working on content for an Oracle WebLogic YouTube channel to host demos and overview of WebLogic features.  The goal is to provide short educational overviews and demos of new, useful, or 'hidden gem' WLS features that may be underutilized.  We currently have 26 videos including Advanced JMS features, WLST and JRockit Mission Control.  We also have a few videos about our JRockit Virtual Edition software that is pretty neat. We will be making ongoing updates to the content.  We really do want people to give us feedback on what they want to see with regard to WebLogic.  Whether its how you achieve a certain architectural goal with WLS or a demonstration and sample code for a feature - All requests related to WLS are welcome! You can find the channel here: http://www.YouTube.com/OracleWebLogic.  Please comment on the Channel or our WebLogic Server blog to let us know what you think.  Thanks!
