• help with migrating from Widows, x64 FGLRX, CPU load, Java and Minecraft

  - by joxer

  Im new to ubuntu, it is the second time i have installed it. This comp is Dell studio 1558. some specs: CPU- intel core i7 Q720 1.6GHz, GPU- ATI Mobility Radeon HD 5400 FGLRX- i've fallowed these instructions among inspecting many others, i have tried all of the variants mentioned in that tread before reverting back to the drivers supplied with Ubuntu ( through additional drivers ) which apparently seem to work best. i am testing them with minecraft as silly as it may sound. in 2 to 60 minutes the FPS drop from 70+ to somewhere between 0 and 5. while "fgl_glxgears" runs at between 400 and 800 FPS smoothly.. I am using oracle ( sun ) JRE6 to run minecraft, i have gotten it through a tutorial linked on oracle's website, i currently have no other version of java installed ( was worse when i had a few others here ). after closing the game Ubuntu is similarly slow, i've checked the CPU load using System Monitor and it shows one of the CPU's jumping to 80%~100% load at a time.. a reboot solves it. i realize my mess is up to me to solve but a hand is always appreciated. tyvm in advance.

• Skin Object Tokens for DotNetNuke 5 - 8 Videos

  In this tutorial we demonstrate how to use Skin Object Tokens in DotNetNuke v5 and above. Skin Object tokens are a new skinning method introduced in DotNetNuke 5 for adding tokens into a DotNetNuke skin. A Skin Object Token is a web user control, it covers skin elements such as the logo, menu, search, login links, date, copyright, languages, links, banners, privacy, terms of use etc. This new Object token method has been introduced into DotNetNuke with the idea of making it simpler to add a skin object into a DotNetNuke skin. The videos contain: Video 1 - Introduction to HTML Object Token Skinning Video 2 - Basic Styling of a Skin and Creating Multiple Content Panes Video 3 - Styling, Control Panel, Login and Register Skin Object Tokens Video 4 - Packaging, Installing, Testing and Viewing the ASCX Version of the Skin Video 5 - Viewing the Attributes for Skin Object Tokens, Logo Token, Search Token Video 6 - Breadcrumb Token, Text Token and Localization, Links Token Video 7 - More Skin Tokens and Token Replacement Video 8 - Demonstration of the Object Tokens and Bug Fixing Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• I seem to be missing a few important concepts with PhoneGap

  - by garethdn

  I'm planning on developing an app on multiple platforms and I'm thinking that PhoneGap might be perfect for me. I had been reading that it's one codebase for all platforms but looking at the PhoneGap guide it seems there are separate instructions for each platform. So if i want to develop for iOS, Android, BB and WP7 I need to write 4 different sets of code? I'm sure i'm missing something fundamental here. Aside from that, how do people usually approach a PhoneGap build? You obviously / probably want the finished app to look like a native app - is it more common than not to use jQuery Mobile together with PhoneGap? Is there a preferred IDE? I see, in the guide, for iOS they seem to suggest Xcode. I'm fine using Xcode but it seems a bit overkill for HTML & CSS. Do I need to develop in Xcode and if not how do i approach it? Use a different IDE / Text Editor and then copy paste into Xcode for building and testing? I know this question is long-winded and fundamental but it something which i don't think is properly addressed in the guides. Thanks.

• Globacom and mCentric Deploy BDA and NoSQL Database to analyze network traffic 40x faster

  - by Jean-Pierre Dijcks

  In a fast evolving market, speed is of the essence. mCentric and Globacom leveraged Big Data Appliance, Oracle NoSQL Database to save over 35,000 Call-Processing minutes daily and analyze network traffic 40x faster.  Here are some highlights from the profile: Why Oracle “Oracle Big Data Appliance works well for very large amounts of structured and unstructured data. It is the most agile events-storage system for our collect-it-now and analyze-it-later set of business requirements. Moreover, choosing a prebuilt solution drastically reduced implementation time. We got the big data benefits without needing to assemble and tune a custom-built system, and without the hidden costs required to maintain a large number of servers in our data center. A single support license covers both the hardware and the integrated software, and we have one central point of contact for support,” said Sanjib Roy, CTO, Globacom. Implementation Process It took only five days for Oracle partner mCentric to deploy Oracle Big Data Appliance, perform the software install and configuration, certification, and resiliency testing. The entire process—from site planning to phase-I, go-live—was executed in just over ten weeks, well ahead of the four months allocated to complete the project. Oracle partner mCentric leveraged Oracle Advanced Customer Support Services’ implementation methodology to ensure configurations are tailored for peak performance, all patches are applied, and software and communications are consistently tested using proven methodologies and best practices.

• How do you track existing requirements over time?

  - by CaptainAwesomePants

  I'm a software engineer working on a complex, ongoing website. It has a lot of moving parts and a small team of UI designers and business folks adding new features and tweaking old ones. Over the last year or so, we've added hundreds of interesting little edge cases. Planning, implementing, and testing them is not a problem. The problem comes later, when we want to refactor or add another new feature. Nobody remembers half of the old features and edge cases from a year ago. When we want to add a new change, we notice that code does all sorts of things in there, and we're not entirely sure which things are intentional requirements and which are meaningless side effects. Did someone last year request that the login token was supposed to only be valid for 30 minutes, or did some programmers just pick a sensible default? Can we change it? Back when the product was first envisioned, we created some documentation describing how the site worked. Since then we created a few additional documents describing new features, but nobody ever goes back and updates those documents when new features are requested, so the only authoritative documentation is the code itself. But the code provides no justification, no reason for its actions: only the how, never the why. What do other long-running teams do to keep track of what the requirements were and why?

• Time Zone on WebLogic Server

  - by adejuanc

  In order to configure the time zone with WebLogic Server, use the following JVM startup command: -Duser.timezone=<timezone> For example, in the java arguments in the admin console at Environments -> Servers -> Servername -> - Server Start tab, configure the startup settings that Node Manager will use to start the particular server. For example: -Duser.timezone='America/Arizona' There are many different time zones, each with its own code. For a complete list please refer to : http://en.wikipedia.org/wiki/List_of_zoneinfo_time_zones For testing, you can run the following code on WLS with a JSP, servlet, or deploying the class: import java.util.Calendar; import java.util.TimeZone; public class TestTimeZone {  public static void main(String[] args) {    Calendar calendar = Calendar.getInstance();    TimeZone timeZone = calendar.getTimeZone();    System.out.println(" your Current TimeZone is : " + timeZone.getDisplayName());    System.out.println(" Time Zone id : "+ timeZone.getID());  } }

• TraceTune supports uploading Zip files

  - by Bill Graziano

  I’ve been using the online version of ClearTrace more and more lately.  When I get to a new client it’s just much easier to upload a trace file rather than install ClearTrace. That means I’ve finally been adding more features to it.  The two latest features are around ease of use. You can now upload a ZIP file that contains a trace file.  Trace files are already somewhat compressed.  Putting it in a ZIP file further compresses it by a factor of 8X or 9X in my testing. That means you can start with a 100MB trace and end up with a 10Mb-12MB ZIP file to upload.  I’m consistently able to get over 150,000 events in a 100MB ZIP file.  That gives me a pretty good look at a system. The second part of this is that files are now processed asynchronously.  After you upload a file you’ll be taken to a processing page that updates every few seconds with the number of rows processed.  It generally takes under a minute to process a 100MB trace file but I *hated* staring at a blank screen. Give TraceTune a try.  It’s getting easier to use every day.

• How To Export/Import a Website in IIS 7.x

  - by Tray Harrison

  IIS 6 had a great feature called ‘Save Configuration to a File’ which would allow you to easily export a website’s configuration, to be later used to import either on the same server or another box.  This came in handy anytime you wanted to duplicate a site in order to do some testing without impacting the existing application.  So naturally, Microsoft decided to do away with this feature in IIS 7. The process to export/import a site is still fairly simple, though not as obvious as it was in previous versions.  Here are the steps: 1. Open a command prompt and navigate to C:\Windows\System32\inetsrv and run the following command: appcmd list site /name:<sitename> /config /xml > C:\output.xml So if you were wanting to export a website named EAC, you would run the following: If you’ll be setting up another copy of the site on the same server, you’ll now need to edit the output.xml file before importing it.  This is necessary in order to avoid conflicts such as bindings, Site ID, etc.  To do this, edit the XML and change the values.  Go ahead and make a copy of the home directory, and rename it to whatever folder name you specified in the output – /EAC2 in this example.  If you decide to change the app pool, make sure you go ahead and create the new app pool as well. Once these edits have been made, we are now ready to import the site.  To do that run: appcmd add sites /in < c:\output.xml So for our example it would look like this: That’s it.  You should now see your site listed when opening up Inet Manager.  If for some reason the site fails to start, that’s probably because you forgot to create the new app pool or there is a problem with one of the other parameters you changed.  Look at the System log to identify any issues like this.

• Should Android and iPhone UI be different?

  - by Phonon

  I'm not completely new to developing apps, but I'm at a point where I'm trying to develop something and deploy it on several mobile platforms. To only concentrate on two major ones, suppose I'm developing an app for Android and iPhone and designing UI and the general user interaction architecture. Both platforms give guidelines as to how their UIs should work. For example, most iPhone apps have the Navigation Bar (the one that says Testing 1 and has a Back button) and an Icon Bar for navigating a program, while Android uses an Options Menu fetched via a Menu button and the "back" navigation is handled with the physical Back button on the device. I've seen many apps that try to force the same UI on every platform. For example, custom-building an iPhone style Icon Bar and putting it in their Android apps, but it just doesn't quite look right to me and it feels like it violates UI design guidelines somewhat. Are there any good design patters for implementing something sufficiently similar on both platforms, yet still platform-specific enough so that the user would not feel out of their comfort zone? What do people usually do in these situations?

• Is now the right time to move to .NET 4?

  - by bconlon

  The reason I pose this question is that I'm looking at WPF development and so using the latest version seems sensible. However, this means rolling out the .NET 4 runtime to PCs on old versions of the framework. Windows XP is still the number one O/S (estimated 40%+ market share). To run .NET 4 on XP requires Service Pack 3, and although it is good practice to move to the latest service packs, often large companies are slow to keep up due to the extensive testing involved. In fact, .NET 4 is not installed as standard with any Windows O/S as yet - Windows 7 and 2008 Server R2 have 3.5 installed. This is not quite as big an issue as it was for .NET 3.5 as .NET 4 is significantly smaller as it doesn't include the older runtimes - .NET 3.5 SP1 included .NET 3 and .NET 2 and was 250MB, although this was reduced by doing a web install. The size is also reduced a bit if you target the .NET 4 Client Profile, which should be OK for many WPF applications, and I think this may be rolled out as part of Windows service packs soon. But still, if your application is only 4-5 MB and you need 40-50 MB of Framework it is worth consideration before jumping in and using the new shiny features. #

• For an ORM supporting data validation, should constraints be enforced in the database as well?

  - by Ramnique Singh

  I have always applied constraints at the database level in addition to my (ActiveRecord) models. But I've been wondering if this is really required? A little background I recently had to unit test a basic automated timestamp generation method for a model. Normally, the test would create an instance of the model and save it without validation. But there are other required fields that aren't nullable at the in the table definition, meaning I cant save the instance even if I skip the ActiveRecord validation. So I'm thinking if I should remove such constraints from the db itself, and let the ORM handle them? Possible advantages if I skip constraints in db, imo - Can modify a validation rule in the model, without having to migrate the database. Can skip validation in testing. Possible disadvantage? If its possible that ORM validation fails or is bypassed, howsoever, the database does not check for constraints. What do you think? EDIT In this case, I'm using the Yii Framework, which generates the model from the database, hence database rules are generated also (though I could always write them post-generation myself too).

• Jet Brains release WebStorm 5.0

  - by TATWORTH

  At http://www.jetbrains.com/webstorm/whatsnew/index.html?WS50ROW, Jet Brains have announced the release of WebStorm 5.0, an IDE that brings the ease of code writing in VB.NET and C# that you get with ReSharper, to JavaScript, CSS and LESS. (There are some more details in http://blog.jetbrains.com/webide/2012/08/liveedit-plugin-features-in-detail/)Code completion in JavaScript, CSS and LESS is a very welcome feature. I look forward to trying out Web Storm. The download at http://www.jetbrains.com/webstorm/download/index.html comes with a free 30-day trial).Price information is at http://www.jetbrains.com/webstorm/buy/index.jsp - you should note that if you are an open-source developer, you can apply for a free license. The price of a personal license at £23 + VAT is a no-brainer. The price of a Commercial license would have been paid for in a few days of the increased productivity that this tool brings.Web Storm currently requires Google Chrome to run. Like ReSharper it appears to be a very able tool. It includes tools such as:XSLT debuggingJSLint for checking for JavaScript errorsJavaScript debuggingJavaScript unit testing (including code coverage)JavaScript folding regionsCoffeeScript supportWell I suggest that you try WebStorm 5.0

• Please, tell us how you made Agile work for you?

  - by Paul

  I've been seeing many questions related to Agile. There seems to be confusion between the people who are doing Agile successfully, and those of us who don't understand it. So I'm wondering if some of the successful teams would be willing to give the result of us some examples of how you succeeded. Some of the things I know I wonder What steps did you use? (ie. Talk to users, mock up, tests, code, testing, (whatever)) Tools that helped you? Did you generate any artifacts, other than a working implementation? How did you prevent spaghetti architecture / code? How do you pass along to new team members, or is the team stable for the project How did you determine exit criteria, or was it open ended. (Scope of project?) Did you do this as contracting? How did you develop a contract up-front? Did the business do any up front work? Or did they come to the table with "We want to implement a "bleh bleh blah"? What types of tests did you use? Unit, Integration, UAT? Or did the process make some/all of those unnecessary? Bonus: Do you have an situations / links to "How To" Agile articles, books, etc? Wiki, describes what but not how (to the uninitiated) At least to me, not a duplicate

• Dependency Injection and method signatures

  - by sunwukung

  I've been using YADIF (yet another dependency injection framework) in a PHP/Zend app I'm working on to handle dependencies. This has achieved some notable benefits in terms of testing and decoupling classes. However,one thing that strikes me is that despite the sleight of hand performed when using this technique, the method names impart a degree of coupling. Probably not the best example -but these methods are distinct from ... say the PEAR Mailer. The method names themselves are a (subtle) form of coupling //example public function __construct($dic){ $this->dic = $dic; } public function example(){ //this line in itself indicates the YADIF origin of the DIC $Mail= $dic->getComponent('mail'); $Mail->setBodyText($body); $Mail->setFrom($from); $Mail->setSubject($subject); } I could write a series of proxies/wrappers to hide these methods and thus promote decoupling from , but this seems a bit excessive. You have to balance purity with pragmatism... How far would you go to hide the dependencies in your classes?

• Is white the best base color to start with when planning to shade sprites within Unity?

  - by SpartanDonut

  I'm looking into prototyping a game in Unity which will consist of solid square sprites / tiles. I figure I can represent different types of objects with different colors for each of the tiles in the game. I figure that I can import a single square sprite and shade it appropriately in Unity as opposed to imported squares of many different colors. My experience with adjusting the hue and saturation within Photoshop shows that white is not an easy color to change as things that are white often stay white. My testing in Unity shows that I can change the "color" of a sprite to anything other than white and the sprite is seemingly shaded appropriately, despite what I would have thought given my Photoshop experience. Since white objects do seem to take on the appropriate color shading when changed within Unity my gut tells me that this is the best base color to begin with, meaning that I can import a single white square sprite and simply adjust the color to represent different objects and object states. Is a white sprite actually the best color sprite to begin with and why does something like this work in Unity as opposed to adjusting the hue and saturation within Photoshop?

• Storing editable site content?

  - by hmp

  We have a Django-based website for which we wanted to make some of the content (text, and business logic such as pricing plans) easily editable in-house, and so we decided to store it outside the codebase. Usually the reason is one of the following: It's something that non-technical people want to edit. One example is copywriting for a website - the programmers prepare a template with text that defaults to "Lorem ipsum...", and the real content is inserted later to the database. It's something that we want to be able to change quickly, without the need to deploy new code (which we currently do twice a week). An example would be features currently available to the customers at different tiers of pricing. Instead of hardcoding these, we read them from database. The described solution is flexible but there are some reasons why I don't like it. Because the content has to be read from the database, there is a performance overhead. We mitigate that by using a caching scheme, but this also adds some complexity to the system. Developers who run the code locally see the system in a significantly different state compared to how it runs on production. Automated tests also exercise the system in a different state. Situations like testing new features on a staging server also get trickier - if the staging server doesn't have a recent copy of the database, it can be unexpectedly different from production. We could mitigate that by committing the new state to the repository occasionally (e.g. by adding data migrations), but it seems like a wrong approach. Is it? Any ideas how best to solve these problems? Is there a better approach for handling the content that I'm overlooking?

• Have you Been Missing the 'About This Record' Functionality on the Customer Form...?

  - by MargaretW

  Do you have fond memories of the 'Help -> About This Record'  functionality that used to be available in the old Customer form - when it was a form, and not a java html screen?  Back in Release 11i, we had the ability to identify when the customer record had last been updated and by whom.  When some forms were replaced by Java HTML screens, you could identify some of this information via the 'About this Page' hyperlink at the bottom left hand corner of the HTML page.  You could enable this by enabling the FND: Diagnostics profile option, but many customers found this had an adverse effect on performance and additionally was not user-friendly.   Our customers tell us that this feature was widely used to identify owner/update information in many business processes, including auditing, customer entry/update, research and testing.  There have been various efforts to revert this feature by customising java pages, but this was not fully successful in some cases.  Oracle Support is happy to announce that this functionality has now been included in the Customer screens in Release 12.2 onwards.   You will be able to query the record history at customer level, at site level, at site address levels and for all tabs relating to the customer. Simply click on the 'Record History' icon, available in the Record History column on a summary screen, or via the same icon on the individual detail screen to display the following information: Last Updated Date: Last Updated By Creation Date Created By Last Update Login

• Just installed 13.10 and everything is fine except I cannot connect to the internet. Any thoughts?

  - by razorccatu

  I just installed Ubuntu 13.10 on my HP G62 laptop and the install went smoothly. I did the install off of a USB drive after trying ubuntu. While I was testing it, I connected to my Wireless with out issue and surfed a little. After the install, no wireless. I can still connect to my wireless network (at least it tells me I'm connected at full strength) but No servers can be found. I attempted to ping Google to no avail and I attempted to ping my router to no avail. I tried to then hard wire the machine and once again it told me that I was connected but I was not. When I ran dmesg, I got the following message: Warning: nss-myhostname is not installed. Changing the local hostname might make it unresolvabe. Please install nss-hostname! Is the hostname the issue? if so, how do I resolve it with out internet connection? If it's not the issue, how do I move forward? Thanks for any help. EDIT. I forgot to attach the image of my ifconfig if that might help.

• High Availability

  - by mattjgilbert

  Udi Dahan presented at the UK Connected Systems User Group last night. He discussed High Availability and pointed out that people often think this is purely an infrastructure challenge. However, the implications of system crashes, errors and resulting data loss need to be considered and managed by software developers. In addition a system should remain both highly reliable (backwardly compatible) and available during deployments and upgrades. The argument is that you cannot be considered highly available if your system is always down every time you upgrade. For our recent BizTalk 2009 upgrade we made use of our Business Continuity servers (note the name, rather than calling them Disaster Recovery servers ? ) to ensure our clients could continue to operate while we upgraded the Production BizTalk servers. Then we failed back to the newly built 2009 environment and rebuilt the BC servers. Of course, in the event of an actual disaster there was a window where either one or the other set were not available to take over – however, our Staging machines were already primed to switch to production settings, having been used for testing the upgrade in the first place.   While not perfect (the failover between environments was not automatic and without some minimal outage) planning the upgrade in this way meant BizTalk was online during the rebuild and upgrade project, we didn’t have to rush things to get back on-line and planning meant we were ready to be as available as we could be in the event of an actual disaster.

• What is the recommended way to empty a SSD?

  - by Lekensteyn

  I've just received my new SSD since the old one died. This Intel 320 SSD supports TRIM. For testing purposes, my dealer put malware, err, Windows on it. I want to get rid of it and install Kubuntu on it. It does not have to be a "secure wipe", I just need the empty the disk in the mosy healthy way. I believe that dd if=/dev/zero of=/dev/sda just fills the blocks with zeroes and thereby taking another write (correct me if I'm wrong). I've seen the answer How to enable TRIM, but it looks like it's suited for clearing empty blocks, not wiping the disk. hdparm seems to be the program to do it, but I'm not sure if it clears the disk OR cleans empty blocks. From its manual page: --trim-sector-ranges For Solid State Drives (SSDs). EXCEPTIONALLY DANGEROUS. DO NOT USE THIS OPTION!! Tells the drive firmware to discard unneeded data sectors, destroying any data that may have been present within them. This makes those sectors available for immediate use by the firmware's garbage collection mechanism, to improve scheduling for wear-leveling of the flash media. This option expects one or more sector range pairs immediately after the option: an LBA starting address, a colon, and a sector count, with no intervening spaces. EXCEPTIONALLY DANGEROUS. DO NOT USE THIS OPTION!! E.g. hdparm --trim-sector-ranges 1000:4 7894:16 /dev/sdz How can I make all blocks appear as empty using TRIM?

• I installed ubuntu, the installer told me to reboot afterwards. I dd, and now linux wont boot

  - by mandy

  Im trying to dual boot between mac 10.6.8 and ubuntu 11.10. I have a macbook pro 8,1. So i installed from a 10.04 disk because the install window makes more sense to me, and it doesnt give me errors or anything. Also, any versions of ubuntu after that dont boot from disk for whatever reason. (i think its having to do with the efi boot thing. i have to get ubuntu 11.10 to boot from a usb with folders bootefiboot.iso) Then my plan after that was after the ubuntu 10.04 install took care of all the swap and stuff for me without being messy, to upgrade to 11.10. So here i have 10.04 booting successfully back and forth from mac osx no problem. I put in my 11.10 usb and the installer gives me the option to "update 10.04 to 11.10" bingo, jackpot, thats what i want. Everything proceeds as normal, as EVERY OTHER install of ubuntu i have ever done, then the installer finishes and says HEY! im finished! Continue testing or reboot now! So i reboot, and what do i get??? A black screen that says the file system isnt found, to enter a boot disk and press any key. WHAT THE HELL????? so i boot the 11.10 installer again from usb, and select "erase 11.10 and install 11.10", installer proceeds normally, and asks me to reboot. I reboot and get the SAME THING. Please, someone, help me get this right here. This is my first time actually dual booting between mac and linux. Usually i just wipe off osx completely and install ubuntu but i actually need to keep my mac partition this time. I have successfully installed 11.10 on this machine before, but that was when i did a clean install. Help?

• Ubuntu server is dropping SSH connections, then not allowing me to log back on

  - by wilhil

  I have an ESX box which I have loaded with two Ubuntu Server machines. During setup, I chose no additional packages to install as I just wanted a lightweight machine for testing. The first thing I did was change the root password via sudo passwd After ESX got on my nerves through lag, I decided to install OpenSSH via apt-get install openssh-server. It did it's business, and I then opened putty and could connect in to both machines fine. The first time it connected, it asked me to add the ssh key as obviously it did not know it. Anyway, the second server is working flawlessly, but, the first seems to be giving me trouble. I was in the middle of typing a sentence when it kicked me off for no reason and when I tried to reconnect, putty gave me a warning that the ssh key had changed and it is potentially dangerous. I attempted to log in anyway and it did not work, just the standard access denied message. Using the second machine, I SSHed in to the first machine and it worked straight away, I then killed the SSH sessions (and possibly SSH server), I then reconnected via putty and I again received the security warning message, but, it allowed me to log on fine. ... I thought "glitch" and nothing more of it, but, it just happened again! I really do not understand this and was hoping someone here can help?
