  • Teamwork 101 for the solo newbie

    - by clankercrusher
    Forgive my newbishness but I have a question to ask about teamwork...mainly because I stink at it. Most of my projects up until this point have been solo so I have a very limited experience with teamwork. I did make graphics for a game that was being developed by several people, but that was completely different than programming with several different people. Right now I'm working with someone else on an indie MMO along with a few other team members. I've already made some pretty stupid mistakes, (like rewriting EVERYTHING) so I have two questions for you guys: 1) What are some of the most common mistakes that people make in a team environment and how can they be avoided? 2) How can the structure of your program be altered to allow for multiple teams members to work on different parts of the program at the same time? P.S. Is this the right stack exchange site for this type of question? (if not, where does it go? Thanks)

  • Modular Open MMO RPG

    - by Chris Valentine
    Has there been an MMORPG type attempt at some kind of open universe where you could host a server on your own if you wish and it would merely be added to the collective of possible places to travel within the MMO? Two types come to mind, a DnD Neverwinter Nights type place or something like EVE online. Where there is a "universe" and each hosted space is a planet or solar system or galaxy and players can travel between them using the same characters/ships/portal system and each new server is than just a new adventure or place to go. I would also assume there were dedicated/replicated servers that housed the characters/inventory themselves so that the environment was decentralized and always expandable. Not sure thats clear but has there been any such attempts or WIP? thanks

  • Is there a way to hide & reveal the launcher at will with the press of a key?

    - by thanos
    I'm using Ubuntu 12.04 with the default Unity desktop environment. I'm aware of all the keyboard shortcuts that relate to the launcher as well as the possible tweaks using Ubuntu Tweak Tool, Unsettings, MyUnity. What I'd like to know is this: Is there a way to hide & reveal the launcher at will with the press of a key? Example given, press Key A, launcher hides, press Key A again and launcher is revealed until I press the A Key once more and so forth. The autohide function won't do because I want the launcher to stay visible once revealed.

  • Installing Ubuntu 14.04 on macbook pro EFI

    - by user279771
    Macbook pro: mavericks, 5.2, graphics: nvidia geforce 9600M I followed the guides from here: https://help.ubuntu.com/community/UEFIBooting#Detect_.28U.29EFI_firmware_processor_architecture and http://www.rodsbooks.com/ubuntu-efi/. What I have is the following: /dev/sda apple partitions /boot / (root) swap When installing ubuntu, I did not install the boot loader during installation but did so in a chroot environment after installing grub-efi. I installed grub to /dev/sda1 (efi) which created the grub64.efi file in efi/ubuntu. This allows the refined boot manager to bring up grub and select ubuntu however, the graphics does not work. Even after adding nomodeset and removing quiet/splash from the kernel parameters. Any ideas on what could be wrong? To be clear, if I remove quiet/splash, I can see all the text startup messages being printed out however, the display manager doesn't appear to start (the screen stays black). Oddly enough though, the ubuntu startup sound can be heard.

  • Unit test and Code Coverage of Ant build scripts

    - by pablaasmo
    In our development environment We have more and more build scripts for ant to perform the build tasks for several different build jobs. These build scripts sometimes become large and do a lot of things and basically is source code in and of itself. So in a "TDD-world" we should have unit tests and coverage reports for the source code. I found AntUnit and BuildFileTest.java for doing unit tests. But it would also be interesting to know the code coverage of those unit tests. I have been searching google, but have not found anything. Does anyone know of a code coverage tool for Ant build scripts?

  • User Experience Fundamentals

    - by ultan o'broin
    Understanding what user experience means in the modern work environment is central to building great-looking usable applications on the desktop or mobile devices. What better place to start a series of blog posts on such Applications User Experience team enablement for customers and partners than by sharing what the term really means, writes team member Karen Scipi. Applications UX have gained valuable insights into developing a user experience that reflects the experience of today’s worker. We have observed real workers performing real tasks in real work environments, and we have developed a set of new standards of application design that have been scientifically proven to be beneficial to enable today’s workers. We share such expertise to enable our customers and partners to benefit from our insights and to further their return on investment when building Oracle applications. So, What is User Experience? ?The user interface (UI) is about the on-screen user context provided by the layout of widgets (such as icons, fields, and buttons and more) and the visual impact of colors, typographic choices, and so on. The UI comprises the “look and feel” of the application that users interact with, and reflects, in essence, the most immediate aspects of usability we can now all relate to.  User experience, on the other hand, is about understanding the whole context of the world of work, how workers go about completing tasks, crossing all sorts of boundaries along the way. It is a study of how business processes and workers goals coincide, how users work with technology or other tools to get their jobs done, their interactions with other users, and their response to the technical, physical, and cultural environment around them. User experience is all about how users work—their work environments, office layouts, desk tools, types of devices, their working day, and more. Even their job aids, such as sticky notes, offer insight for UX innovation. User experience matters because businesses needs to be efficient, work must be productive, and users now demand to be satisfied by the applications they work with. In simple terms, tasks finished quickly and accurately for a business evokes organization and worker satisfaction, which in turn makes workers feel good and more than willing to use the application again tomorrow. Design Principles for the Enterprise Worker The consumerization of information technology has raised the bar for enterprise applications. Applications must be consistent, simple, intuitive, but above all contextual, reflecting how and when workers work, in the office or on the go. For example, the Google search experience with its type-ahead keyword-prompting feature is how workers expect to be able to discover enterprise information, too. Type-ahead in PeopleSoft 9.1 To build software that enables workers to be productive, our design principles meet modern work requirements about consistency, with well-organized, context-driven information, geared for a working world of discovery and collaboration. Our applications must also behave in a simple, web-like way just like Amazon, Google, and Apple products that workers use at home or on the go. Our user experience must also reflect workers’ needs for flexibility and well-loved enterprise practices such as using popular desktop tools like Microsoft Excel or Outlook as required. Building User Experience Productively The building blocks of Oracle Fusion Applications are the user experience design patterns. Based on the Oracle Fusion Middleware technology used to build Oracle Fusion Applications, the patterns are reusable solutions to common usability challenges that ADF developers typically face as they build applications, extensions, and integrations. Developers use the patterns as part of their Oracle toolkits to realize great usability consistently and in a productive way. Our design pattern creation process is informed by user experience research and science, an understanding of our technology’s capabilities, the demands for simplification and intuitiveness from users, and the best of Oracle’s acquisitions strategy (an injection of smart people and smart innovation). The patterns are supported by usage guidelines and are tested in our labs and assembled into a library of proven resources we used to build own Oracle Fusion Applications and other Oracle applications user experiences. The design patterns library is now available to the ADF community and to our partners and customers, for free. Developers with ADF skills and other technology skills can now offer more than just coding and functionality and still use the best in enterprise methodologies to ensure that a great user experience is easily applied, scaled, and maintained, whether it be for SaaS or on-premise deployments for Oracle Fusion Applications, for applications coexistence, or for partner integrations scenarios.  Oracle partners and customers already using our design patterns to build solutions and win business in smart and productive ways are now sharing their experiences and insights on pattern use to benefit your entire business. Applications UX is going global with the message and the means. Our hands-on user experience enablement through ADF  is expanding. So, stay tuned to Misha Vaughan's Voice of User Experience (VOX) blog and follow along on Twitter at @usableapps for news of outreach events and other learning opportunities.

  • Unity 2d support dropped in 12.10, what now?

    - by tomodachi
    So its been announced. Ubuntu is dropping unity 2d support. I wouldn't mind if it wasn't for two things that are important to me. 1) A working system Unity is nice, i try to use it quite often. But it lags. 2) Support for older hardware. I also have old computers. You can imagine how they would work with unity if my current laptop is slog in Ubuntu. I guess i could use another desktop environment/ window manager , like switching to fluxbox. Anyone have any suggestion ideas/solutions on how to proceed with Ubuntu in the future? All insights welcome

  • Visual Programming paradigms

    - by Rego
    As the number of "visual" OS's such as Android, iOS and the promised Windows 8 are becoming more popular, it does not seem to me that we programmers have new ways to code using these new technologies, due to a possible lack in new visual programming languages paradigms. I've seen several discussions about incompatibilities between the current coding development environment, and the new OS approaches from Windows 8, Android and other tablets OS's. I mean, today if we have a new tablet, it's almost a requirement for coding, to have, for instance, an external keyboard (due it seems to me it's very difficult to program using the touch screen), exactly because the coding assistance is not conceived to "write" thousands of lines of code. So, how advanced should be the "new" visual programming languages paradigms? Which characteristics these new paradigms would be required?

  • Troubleshooting Microsoft Message Queuing Issues on Microsoft Lync Server 2010

    - by John Breakwell
    This blog post sounds specific but most of the troubleshooting tips can be applied to other scenarios: Troubleshooting Microsoft Message Queuing Issues on Microsoft Lync Server 2010 Microsoft Message Queuing (MSMQ) plays an important role in the Microsoft Lync Server 2010 Monitoring/Archiving server infrastructure: in a distributed network environment, MSMQ is used to transmit data from agents located on other servers (such as Front End Servers) to Monitoring/Archiving servers. The purpose of this article is to help you discover the root cause of any MSMQ problems that you might encounter, and to provide suggested ways to fix those problems. Microsoft Lync Server is the new name for Microsoft Office Communications Server. It’s good to see a major product make use of MSMQ – there aren’t many in the public eye (Symantec’s Enterprise Vault comes to mind).

  • Polygon count target range for MMO being released in 2 years

    - by classer
    What would a realistic poly count target range be for NPC and player models in a 3D MMO that will be released in 2 years? What about poly count target range for the entire camera view (environment, NPC and player meshes)? I read in some places that one should not aim too low if the game will come out in a couple years because technology is always advancing. If you can give some mesh poly stats on what other current MMOs / MMORPGs are running and future projections, that would be great. Thank you.

  • Ubuntu 13.10 AdobeAIR application: Failed to load module "unity-gtk-module"

    - by nobuzz
    I have installed AdobeAIR on 13.10, but am getting the following error messages when using: Gtk-Message: Failed to load module "overlay-scrollbar" Gtk-Message: Failed to load module "unity-gtk-module" Has someone faced this issue. I looked at comment giving a possible resolution here , but that didn't help, as I already have those packages installed. Basically to install AdobeAIR, being a 32-bit, I had to install various i386 packages: libgtk2.0-0:i386 libnss3-1d:i386 libnspr4-0d:i386 lib32nss-mdns libxml2:i386 libxslt1.1:i386 When I run the program as root, it opens up properly without errors. But that is not an option. Could it be a problem that necessary modules are not getting loaded on non-root user's environment.

  • Using IP Restrictions with URL Rewrite-Week 25

    - by OWScott
    URL Rewrite offers tremendous flexibility for customizing rules to your environment. One area of functionality that is often desired for URL Rewrite is to allow a large list of approved or denied IP addresses and subnet ranges. IIS’s original IP Restrictions is helpful for fully blocking an IP address, but it doesn’t offer the flexibility that URL Rewrite does. An example where URL Rewrite is helpful is where you want to allow only authorized IPs to access staging.yoursite.com, but where staging.yoursite.com is part of the same site as www.yoursite.com. This requires conditional logic for the user’s IP. This lesson covers this unique situation while also introducing Rewrite Maps, server variables, and pairing rules to add more flexibility. This is week 25 of a 52 week series for the Web Pro. Past and future videos can be found here: http://dotnetslackers.com/projects/LearnIIS7/ You can find this week’s video here.

  • Monitoring almost anything with BizTalk 360

    - by Michael Stephenson
    When you work in an integration environment it is common that you will find yourself in a situation where you integrate with some unusual applications or have some unusual dependencies. That is the nature of integration. When you work with BizTalk one of the common problems is that BizTalk often is the place where problems with applications you integrate with are highlighted and these external applications may have poor monitoring solutions. Fortunately if you are a working with a customer who uses BizTalk 360 then it contains a feature called the "Web Endpoint Manager". Typically the web endpoint manager is used to monitor web services that you integrate with and will ping them at appropriate times to make sure they return the expected HTTP status code. When you have an usual situation where you want to monitor something which is key to the success to your solution but you find yourself having to consider a significant custom solution to monitor the external dependency then the Web Endpoint Manager could be your friend. The endpoint manager monitors a url and checks for a certain status code. This means that you can create your own aspx web page and then make BizTalk 360 monitor this web page. Behind the web page you could write any code you wished. An example of this is architecture is shown in the below diagram.     In the custom web page you would implement some custom code to do whatever it is that you want to monitor. In the below code snippet you can see how the Page_Load default method is doing some kind of check then depending on the result of the check it returns a certain HTTP code. protected void Page_Load(object sender, EventArgs e) { var result = CheckSomething();   if (result == "Success") Response.StatusCode = 202; else if (result == "DatabaseError") Response.StatusCode = 510; else if (result == "SystemError") Response.StatusCode = 512; else Response.StatusCode = 513;   }   In BizTalk 360 you would go into the Monitor and Notify tab and then to BizTalk Environment which gives you access to the Web Endpoint Manager. You need an alarm setup which configures how the endpoint will be checked. I'm not going to go through the details of creating the alarm as this is already documented in the BizTalk 360 documentation. One point to note is that in the example I am using I setup a threshold alarm which means that the url is checked about every minute and if there is an error that persists for a period of time then the alarm will raise the alert notification. In my example I configured the alarm to fire if the error persisted for 3 minutes. The below picture shows accessing the endpoint manager.   In the web endpoint manager you would then configure your endpoint to monitor and the HTTP response code which indicates all is working fine. The below picture shows this. I now have my endpoint monitoring setup and BizTalk 360 should be checking my custom endpoint to see that it is available. If I wanted to manually sanity check that the endpoints I have registered are working fine then clicking the Refresh button will show if they are all good or not. If my custom ASP.net page which is checking my dependency gets a problem you will see in the endpoint manager that the status code does not match the expected return code and your endpoints will display in red and you can see the problem. The below picture shows this. If I use specific HTTP response codes for the errors the custom ASP.net page might encounter I can easily interpret these to know what the problem is. Using the alarms and notifications with BizTalk 360 it means when your endpoint goes into an error state you can easily configure email or SMS notifications from BizTalk 360 to tell you that your endpoint is having problems and you can use BizTalk 360 to help correlate what the problem is to allow you to investigate further. Below you can see the email which tells me my endpoint is not working.   When everything returns to normal you will see the status is now fixed and you will see a situation like below where you can see the WebEndpoints are now green and the return code matches what is expected.   Conclusion As you can see it is really easy to plug your own custom ASP.net page into the BizTalk 360 web endpoint monitoring feature. This extension then gives you the power to really extend the monitoring to almost anything you want as long as you can write some .net code to check that the dependency is available and working. It would be interesting to hear of any ideas people have around things they would monitor with this extension. More details on the end point monitor can be found on the following link: http://www.biztalk360.com/tour/monitoring_notifications

  • Ubuntu 13.10 gives "Package 'libapache2-mod-auth-mysql' has no installation candidate" error

    - by John Crawford
    I'm trying to install my LAMP environment on Ubuntu 13.10 using my script file that can be found here. That script worked for Ubuntu 12.04, Ubuntu 13.04 but when I try it on Ubuntu 13.10 it gives the following error: E: Package 'libapache2-mod-auth-mysql' has no installation candidate Any idea on how to fix this? Note, I do want this package to be installed. EDIT: I've found out now that the reason this could not be installed was because it needed the following two packages that were missing: libmysqlclient16 and apache2.2-common. Do I just need to install these packages or were they removed for a reason?

  • CMS DITA North America Conference / Agile Doc

    - by ultan o'broin
    I attended and presented, along with a colleague, at the Content Management Strategies DITA North America Conference 2010 in Santa Clara this week. It was touch and go whether I would make it across the Atlantic, but as usual the Irish always got through! Our presentation was about DITA and Writing Patterns, and there was three other presentations from Oracle folks too, all very well delivered and received. The interaction with other companies was superb, and the sparks of innovation that flew as a result left me with three use case ideas for UX investigation and implementation. My colleague had a similar experience. Well worth attending! One of the last sessions was about Authoring in an Agile environment, presented by Julio Vasquez. This was an excellent, common sense, and forthright no-nonsense delivery that made complete sense to me. I'd encourage you, if you are interested in the subject, to check out Julio's white paper on the subject too, available from the SDI website.

  • Do You Want "Normal?" Good luck!

    - by steve.diamond
    Much has been written about "The New Normal." One thing is for sure: whatever THAT is, economically speaking we won't be experiencing it anytime soon. Sure, we're well beyond the "no floor" perception of 18 months ago--which is certainly comforting, but ask any senior executive and they'll tell you of the constant rigor necessary to continually adapt to an ever-changing macro environment. This brings me to a suggestion that you tune in to a Deloitte Webinar titled, "The New Normal: Embrace Complexity or Seek to Simplify." It features the perspectives on this very topic of Jessica Blume, a principal at Deloitte; and Kirk Mosher, VP of CRM Marketing at Oracle.

  • Data, Log and Temp file placement

    - by jchang
    First especially for all the people with SAN storage, drive letters are of no consequence. What matters is the actual physical disk layout. Forget capacity, pay attention to the number of spindles supporting each RAID group. If the RAID group is shared with other application, make sure there the SLA guarantees read and write latency. One very large company conducted a stress test in the QA environment. The SAN admin carved the LUNs from the same pool of disks as production, but thought he had a really...(read more)

  • Camtasia Studio

    - by Andy Morrison
    Have you heard about this tool? This is a capture tool that records your actions as you perform them on your workstation, remote desktop, etc.  It's made by the same company that makes SnagIt, etc. http://www.techsmith.com/camtasia.asp I have used this at several customers to record our install and configurations of BizTalk and more - this can come in very handy to help reduce differences in environments (because you can go back and review exactly what you did in the previous environment) as well as to supplement your installation docs.   The product also includes an editing studio and various media types for export. I haven't been paid to write this - I just think the tool is very nice.

  • Linux Mint is Brilliant

    - by Simon Moon
    Most of my blog posts sound way too whiny. I'm not that guy. (Am I?) I've been using SUSE-flavored Linux for personal projects since 2002 (SUSE Linux 8.1). This past weekend, I made the heart-wrenching decision to abandon openSUSE (version 12.1) in favor of Linux Mint (version Maya). OpenSUSE had just become too burdensome. Packages that installed easily on RedHat or Debian always had issues running on top of OpenSUSE. And I never could get the Heroku Toolbelt installed in any kind of usable state.And so, ...I'm beginning again with this enticing young thing -- Mint with the Cinnamon window environment. Delicious. And while I'll always have fond memories of my years with openSUSE, I've got to admit that Mint makes running Linux feel good again. http://blog.linuxmint.com/?p=2031

  • Java doesn't show up in firefox plugins

    - by user857990
    I've just installed the newest java, because firefox blocks the old version. I used the tutorial from http://www.backtrack-linux.org/wiki/index.php/Java_Install Because I had some trouble once, I knew that there are multiple library folders, so I linked into all mozilla plugin folders that there are. /root/.mozilla/plugins /usr/lib/firefox/plugins/ /usr/lib/firefox-addons /usr/lib/mozilla/plugins /usr/lib64/mozilla/plugins java -version returns java version "1.7.0_07" Java(TM) SE Runtime Environment (build 1.7.0_07-b10) Java HotSpot(TM) 64-Bit Server VM (build 23.3-b01, mixed mode) But when I go to firefox plugins, it's not listed. What do I need to do, so that firefox recognizes java?
