  • I have a ESXi 5.0 installed and when I am Installing Ubuntu Server 12.04 LTS it is giving an error saying grub installation failed?

    - by Rishee
    I have a ESXi 5.0 installed and when I am Installing Ubuntu Server 12.04 LTS (32 bit) it is giving an error saying grub installation failed? Please check the below screenshot of the error. I have other Ubuntu servers running fine on this esxi server, so I don't think problem is with ESXi. I have 32 GB of ram spare on this ESXi and have given 2 GB of RAM to this 12.0 LTS VM. I have given 2 cores of processor. I have tried supplying different ISO Image to this VM as I thought the 1st image that I downloaded has errors.. But defiantly that's not the case as all 3 different ISO images that I downloaded of Ubuntu server 12.04 LTS (32-bit) can't be corrupt!! Just to make sure that the Image does not have problem I used that Image to install it for testing on stand alone system. it works fine there!! This is a production ESXi server with which I can't play with, how ever I can play whith the Ubuntu Server 12.04 LTS (32-Bit) VM that we have created on that ESXi. I need help on this as soon as possible. go live date of this server is really close. (This Question is already there on Super user and Server Fault.)

  • Blank screen after Switch User or Resume

    - by matt wilkie
    About half the time when I switch users or resume from standby or resume the screen goes blank (black). If I work the cursor keys I can hear the system bell when it gets to the end of the user list. I can also successfully login, going from memory, but screen stays black. Sometimes closing and re-opening the lid will light up the screen again. Pressing the special Function key to enable/disable external monitor connection has no effect [Fn]-[F5],[Fn]-[F6]. If none of the previous work I need to put the computer into hibernation or full power off to restore screen function. If I watch closely when switching users I think I can see the screen initially start to light up and then quickly fade to black. The computer is an Acer Aspire 3500, model ZL6, running Ubuntu 10.10 installed 2 days ago. No proprietary drivers are in use. I'll provide a list of hardware details as soon as I can figure out how to generate that (didn't there used to be an entry for hardware details under the System menu?). Possibly related questions: No resume after Hibernate or Standby When I resume from suspension - the screen is blank Switch user fails to complete successfully For what it's worth, blank after resume also used to happen occasionally when the laptop was running XP-Home, but nowhere near as often, perhaps 6 or 8 times a year. UPDATE: I found System Administration System Testing and ran the Monitor test. It went very very dark, but the window elements could be discerned, and the whole screen flashed (from very very dark to black). On the third repeat of that same test the screen went to full blaupck and stayed there. Moving the mouse, via touchpad, or touch keys did not wake it up again. I had to close the lid and put the computer into hibernate, and press the power button to restore it. UPDATE2: output of lshw: http://pastebin.com/q7n8676r, lspci: http://pastebin.com/6ujzVK4r UPDATE3: sometimes I can restore the screen by flipping to console 1 with ctrl-alt-F1 and then back to graphical with ctrl-alt-F7.

  • Our New Website Header (& Other Tweaks)

    - by justin.kestelyn
    Last week, the Oracle Technology Network Website went fixed-width. There are several reasons for this, most relating to providing a consistent user experience, easier management of Website content, etc. Furthermore, it's fairly standard for developer portals these days - java.sun.com, MSDN, and IBM DeveloperWorks are also all fixed-width sites. (My apologies to everyone who is unhappy about this change, but it really is an overall positive one.) Today, we have rolled out a brand-new header, the first step in what we call the "Mosaic" project - which is an effort to make the user experience across all Oracle Websites more consistent. To summarize the impact: The "pull-down" menus on the OTN site disappear; most of them move into a "flyout" button in the header. You can access the OTN flyout from any page on Oracle.com or the OTN site. Great for our page views. :) You also have direct access to the Downloads index from anywhere on Oracle.com. If you so desire, you can directly access product overviews, Oracle University and Support info, Oracle Store, etc etc from the OTN site now. Due to limited space in the flyout we cannot accommodate *all* the pull-down items, but they are all no more than 1 or 2 clicks away. This approach has been validated in extensive user testing over the last few months; I welcome your feedback now in comments. There are many other changes in train, with the next one being: A major homepage redesign, the first in 4 or 5 years.

  • Entry / JR Php Programmer - What do I learn next?

    - by dtj
    I got very interested in programming toward the end of college. Took a few classes, but learned most everything on my own via books and such. Its mostly been Php and MySQL. Right out of school, I got a job working at a company for 2 years (web media) and ended up learning a lot of stuff and programming some things for them. I am no longer at that company but I am looking for my next steps as a programmer. I really enjoy Web Development and Php and MySQL seems to be my thing. Basically, I know how to do CRUD operations, i am mediocre at OOP and still have more to learn, I know HTML and CSS quite well, I know my way around a Unix terminal and can access MySQL through it and set up cron jobs and such. I know some basic Javascript. Whats a good next step? I don't anything about 3rd party services, PDO, APIs (twitter, facebook, etc), Drupal / Joomla, Unit Testing, E-Commerce, PECL, PEAR ....in other words A LOT I get easily overwhelmed by the amount of stuff there is to learn, so I'm sort of trying to find a path. Right now, I'm digging into OOP more, as that seems like a good conceptual first-step. Any suggestions?

  • What deployment framework to use?

    - by jeruki
    We are trying to figure out what deployment method/framework to use with a python application, it has a basic wsgi server to make some REST resources available and a set of static web pages with the interface that are served through apache. The situation is as follows: My team works in isolated parts of the program and sometimes together in specific modules, we have different testing servers and one master server, we all work locally, sync the code using git, and then run a bash script that copies the files from the windows machines to the indicated linux server(using ssh) and then restarts the app. After thinking about it this doesn't seem to be the right way to do it, the script overwrites all the files in the server with the local files everytime. We want to be able to work in the same server without the worry of overwriting other people's code and we need to deploy to different servers to avoid restarting the service while others work with it and in the near future we need to deploy to the master or several clones of the master server when the application reaches a more mature state. We found serveral options capistrano, kwate, chef or fortress, even fleet but we wanted to have opinions from people that has used them to be sure it is what we need. So this are the main questions: Are these the kind of programs we should be looking at to achive a safe concurrent deployment process? Which one have you used/recommend and why? do you think it would help in our actual situation? Thank you so much for your feedback and advice on this.

  • How do I structure code and builds for continuous delivery of multiple applications in a small team?

    - by kingdango
    Background: 3-5 developers supporting (and building new) internal applications for a non-software company. We use TFS although I don't think that matters much for my question. I want to be able to develop a deployment pipeline and adopt continuous integration / deployment techniques. Here's what our source tree looks like right now. We use a single TFS Team Project. $/MAIN/src/ $/MAIN/src/ApplicationA/VSSOlution.sln $/MAIN/src/ApplicationA/ApplicationAProject1.csproj $/MAIN/src/ApplicationA/ApplicationAProject2.csproj $/MAIN/src/ApplicationB/... $/MAIN/src/ApplicationC $/MAIN/src/SharedInfrastructureA $/MAIN/src/SharedInfrastructureB My Goal (a pretty typical promotion pipeline) When a code change is made to a given application I want to be able to build that application and auto-deploy that change to a DEV server. I may also need to build dependencies on Shared Infrastructure Components. I often also have some database scripts or changes as well If developer testing passes I want to have an manually triggered but automated deploy of that build on a STAGING server where end-users will review new functionality. Once it's approved by end users I want to a manually triggered auto-deploy to production Question: How can I best adopt continuous deployment techniques in a multi-application environment? A lot of the advice I see is more single-application-specific, how is that best applied to multiple applications? For step 1, do I simply setup a separate Team Build for each application? What's the best approach to accomplishing steps 2 and 3 of promoting latest build to new environments? I've seen this work well with web apps but what about database changes

  • A question about the cobbler-ubuntu-import bash script

    - by user183394
    I have been testing the latest cobbler for PXE booting Ubuntu 12.04.1-server-x86_64 and 12.10-server-x86_64 using a Scentific Linux 6.3 host to run the cobbler server. With the former, I got everything going. But with the later, I haven't been successful. As an attempt to figure things out, I downloaded Ubuntu's cobbler 2.2.2 source package. Examining the content, I soon noticed that Ubuntu's cobbler 2.2.2 came with a cobbler-ubuntu-import bash script. I reviewed the code and spotted something interesting: line 9 of the script states: 9 AUTO_KOPTS='log_host=@@server@@ log_port=514 priority=critical locale=en_US netcfg/choose_interface=auto' But after extensive googling, reading both Debian and Ubuntu's documentation about the debian-installer, I don't see these two kopts log_host and log_port documented anywhere. Putting it in the profile of my current test setup, even my cobbler server host does run rsyslogd, I don't see anything logged either. No, I don't have iptables and selinux on on the cobbler server host. Can anyone point to me where I can read more about these two options? Having the ability to log an installation to a remote central logging host would be really cool.

  • Uganda .NET Usergroup April meeting

    - by Malisa L. Ncube
    Our April meeting was presented by Wilson Kutegeka on the topic of Building the Data Access a layer. In his presentation he showed a tool which he has developed to generate the entities, stores procedures that would be used to reduce having to retype the same boilerplate code for each entity. He uses visual basic samples to demonstrate access to the data from the database and inherits his classes from an abstract class which contains common properties including connection strings, save and delete methods. A number of questions emerged from the group, mostly those that use a business model based approaches. Some of the questions are on unit testing and mocking the models without using the database, the use of IoCs and loose coupled patterns. Some of the questions were on caching, Linq support and data annotations based validation. The presentation details can be found here. Intellisense LTD agreed to sponsor our website and we are glad to have that as we really need to have a website running.

  • Is there a visual web application builder or rapid webapp prototyping framework?

    - by Jesper Mortensen
    Question: Is there such a thing as a self-hosted framework or CMS especially tailored towards the creation of interactive web applications without -- or with an absolute minimum of -- programming? (Substantially less programming than say a simple Rails app or a plugin for Wordpress, Joomla etc would require.) As for desired features I'd settle for whatever is available, but some ideas could be: A User authentication and Permissions system. A GUI-driven input form builder. A GUI-driven template / visual site design builder. A simple scripting language (think AppleScript-like simplicity) A highly modular architecture, with high-level business objects (users, forms data, etc) exposed for easy re-use. If something like the above doesn't exist, then what comes near this? Need: This is for self-hosted rapid prototyping of web applications, and limited user testing of webapp user interface designs in a closed user test. Notes: I know about Ruby on Rails (Rails), Django, Pyramid etc. I'm looking for something much faster to work in, for making prototypes. I know about CMS's in general but find that most of them are tailored towards displaying information to the end users. If there is an exceptionally easy-to-master CMS with easy scripting (lets say much more so than for example Wordpress) then I'd be interested.

  • Rhino Mocks, AssertWasCalled with Arg Constraint on array parameter

    - by Etienne Giust
    Today, I had a hard time unit testing a function to make sure a Method with some array parameters was called. Method to be called : void AddUsersToRoles(string[] usernames, string[] roleNames);   I had previously used Arg<T>.Matches on complex types in other unit tests, but for some reason I was unable to find out how to apply the same logic with an array of strings.   It is actually quite simple to do, T really is a string[], so we use Arg<string[]>. As for the Matching part, a ToList() allows us to leverage the lambda expression.   sut.PermissionServices.AssertWasCalled(                 l => l.AddUsersToRoles(                     Arg<string[]>.Matches(a => a.ToList().First() == UserId.ToString())                     ,Arg<string[]>.Matches(a => a.ToList().First() == expectedRole1 && a.ToList()[1] == expectedRole2)                     )                     );   Of course, iw we expect an array with 2 or more values, the math would be something like : a => a.ToList()[0] == value1 && a.ToList()[1] == value2    … etc.

  • Configuring Transmission for faster download

    I have tested on the same PC with the same torrent/magnet links the following Torrent Clients: Transmission Ktorrent Deluge qBittorrent Vuze After 7 days of testing I noticed that the only one that took longer to start downloading and to keep an optimum/max download speed was Transmission. It was the slowest of them all to download the same torrents or magnet links which I tested 8 torrents and 4 magnet links from different sites and the one that took the most to start downloading or start after a pause/resume event. The other 4 just took less than 2 seconds for example to start downloading and to download the same content between 50% less time to 80% less time. I think that Transmission has the same capabilities about downloading/resuming than the other torrent clients but it may be because of some configuration I need to do to get the same speed and effect than the others. In my tests all torrent clients were tested with their default configurations. No changes were made. They were tested on the same PC, with the same network connection in the same time periods. So I am thinking that Transmission just needs a little bit of configuration tunning. I also set the ports for use to the same one for each. Checked the router for any blocking and anything related to the network. What options can I change to make it so Transmission resumes a download faster (grabs the seeds faster) and keeps a fast download all the time (Stays with the seeds that offer the best connection for example). Both of which by the look of it are features that the rest of the torrent clients do already.

  • Engineering as a Service

    - by jgelhaus
    Oracle Exadata Database Machine is known for great compute performance, and over the past few years, it has also become known as a great platform for any type of Oracle Database workload, from data warehousing to online transaction processing (OLTP). But now organizations are turning to Oracle Exadata for business efficiencies and private cloud solutions—for consolidation and database as a service (DBaaS). University of Minnesota For an inside look at how DBaaS is working in the real world, it’s worth checking into the University of Minnesota’s database hotel.  With more than 50,000 students, the University of Minnesota in Minneapolis is one of the largest universities in the United States. The university’s centralized IT group not only has to support all those students but also must provide support and services to more than 40 departments and colleges within the university. They have two Exadata Database Machine X2-2 half-rack systems from Oracle, with four database nodes each and roughly 30 terabytes of usable disk space for each of the Oracle Exadata systems. The university is using Oracle Real Application Clusters (Oracle RAC) for high availability and the Data Guard feature of Oracle Database, Enterprise Edition, for disaster recovery capabilities. The deployment has been live in production since May 2011. Overhead Door When it comes to overhead, revolving, sliding, or other specialty residential and commercial doors, Overhead Door is the worldwide leader. But when they needed to open doors with their customers through a better, faster, and more agile IT infrastructure, Overhead Door turned to Oracle and Oracle Exadata. Oracle Exadata Database Machine plays an important part in Overhead Door’s IT and business strategy. The organization has two Exadata Database Machine X2-2s deployed, one in production and one in development and testing Read the full Oracle Magazine article Engineering as a Service

  • Do you know the minimum builds to create on any branch?

    - by Martin Hinshelwood
    You should always have three builds on your team project. These should be setup and tested using an empty solution before you write any code at all. Figure: Three builds named in the format [TeamProject].[AreaPath]_[Branch].[Gate|CI|Nightly] for every branch.   These builds should use the same XAML build workflow; however you may set them up to run a different set of tests depending on the time it takes to run a full build. Gate – Only needs to run the smallest set of tests, but should run most if not all of the Unit Test. This is run before developers are allowed to check-in CI – This should run all Unit Tests and all of the automated UI tests. It is run after a developer check-in. Nightly – The Nightly build should run all of the Unit Tests, all of the Automated UI tests and all of the Load and Performance tests. The nightly build is time consuming and will run but once a night. Packaging of your Product for testing the next day may be done at this stage as well. Figure: You can control what tests are run and what data is collected while they are running. Note: We do not run all the tests every time because of the time consuming nature of running some tests, but ALL tests should be run overnight. Note: If you had a really large project with thousands of tests including long running Load tests you may need to add a Weekly build to the mix.     Figure: Bad example, you can’t tell what these builds do if they are in a larger list   Figure: Good example, you know exactly what project, branch and type of build these are for.   Technorati Tags: SSW,SSW Rules,VS2010,VS ALM,Team Build 2010,Team Build

  • PHP rand function (or not so rand)

    - by Badr Hari
    I was testing PHP rand function to write on a image. Of course the output shows that it's not so random. The code I used: <?php header('Content-Type: image/png'); $lenght = 512; $im = imagecreatetruecolor($lenght, $lenght); $blue = imagecolorallocate($im, 0, 255, 255); for ($y = 0; $y < $lenght; $y++) { for ($x = 0; $x < $lenght; $x++) { if (rand(0,1) == 0) { imagesetpixel($im, $x, $y, $blue); } } } imagepng($im); imagedestroy($im); ?> My question is, if I use image width/lenght (variable $lenght in this example) number like 512, 256 or 1024, it is very clear that it's not so random. When I change the variable to 513 for an example, it is so much harder for human eye to detect it. Why is that? What is so special about these numbers? 512: 513: Edit: I'm running xampp on Windows to test it.

  • JDK 7 Feature Complete Milestone Reached

    - by Henrik Ståhl
    The JDK 7 project has reached Feature Complete (FC). This means that development and QA have finished all planned feature and test development work in the release and are moving the focus to testing and bug fixing on all supported JDK 7 platforms. This is a major step towards JDK 7 General Availability (GA) and implies that we are tracking close to the plan published on openjdk.java.net. (The original plan was FC on 12/16. We hit this less than a week late, but verifying that everything was done in time took a couple of weeks due to the intervening holidays.) The definition of the FC milestone allows for exceptions to be integrated later. There are very few such exceptions in the project, the most prominent being updated JAXP/JAXB/JAX-WS and integration of the enhanced JMX agent from JRockit. Our project management does not expect the exceptions to have any negative impact on the release plan. The project may still be delayed if the Expert Groups for the JSRs included in Java SE 7 (203, 292, 334, 336) decide to introduce changes which cannot be accomodated within the existing schedule. Apart from that caveat, Oracle remains confident with the published plan.

  • Questioning the motivation for dependency injection: Why is creating an object graph hard?

    - by oberlies
    Dependency injection frameworks like Google Guice give the following motivation for their usage (source): To construct an object, you first build its dependencies. But to build each dependency, you need its dependencies, and so on. So when you build an object, you really need to build an object graph. Building object graphs by hand is labour intensive (...) and makes testing difficult. But I don't buy this argument: Even without dependency injection, I can write classes which are both easy to instantiate and convenient to test. E.g. the example from the Guice motivation page could be rewritten in the following way: class BillingService { private final CreditCardProcessor processor; private final TransactionLog transactionLog; // constructor for tests, taking all collaborators as parameters BillingService(CreditCardProcessor processor, TransactionLog transactionLog) { this.processor = processor; this.transactionLog = transactionLog; } // constructor for production, calling the (productive) constructors of the collaborators public BillingService() { this(new PaypalCreditCardProcessor(), new DatabaseTransactionLog()); } public Receipt chargeOrder(PizzaOrder order, CreditCard creditCard) { ... } } So dependency injection may really be an advantage in advanced use cases, but I don't need it for easy construction and testability, do I?

  • What does your Lisp workflow look like?

    - by Duncan Bayne
    I'm learning Lisp at the moment, coming from a language progression that is Locomotive BASIC - Z80 Assembler - Pascal - C - Perl - C# - Ruby. My approach is to simultaneously: write a simple web-scraper using SBCL, QuickLisp, closure-html, and drakma watch the SICP lectures I think this is working well; I'm developing good 'Lisp goggles', in that I can now read Lisp reasonably easily. I'm also getting a feel for how the Lisp ecosystem works, e.g. Quicklisp for dependencies. What I'm really missing, though, is a sense of how a seasoned Lisper actually works. When I'm coding for .NET, I have Visual Studio set up with ReSharper and VisualSVN. I write tests, I implement, I refactor, I commit. Then when I'm done enough of that to complete a story, I write some AUATs. Then I kick off a Release build on TeamCity to push the new functionality out to the customer for testing & hopefully approval. If it's an app that needs an installer, I use either WiX or InnoSetup, obviously building the installer through the CI system. So, my question is: as an experienced Lisper, what does your workflow look like? Do you work mostly in the REPL, or in the editor? How do you do unit tests? Continuous integration? Packaging & deployment? When you sit down at your desk, steaming mug of coffee to one side and a framed photo of John McCarthy to the other, what is it that you do? Currently, I feel like I am getting to grips with Lisp coding, but not Lisp development ...

  • Odd Android touch event problem

    - by user22241
    Overview When testing my game I came across a bizarre problem with my touch controls. Note this isn't related to multi-touch as I completely removed my ACTION_POINTER_UP and ACTION_POINTER_DOWN along with my ACTION_MOVE code. So I'm simply working with ACTION_UP and ACTION_DOWN now and still get the problem. The problem I have a left and right button on the left of the screen and a jump button on the right. Everything works as it should but if I touch a large area of my hand (the fleshy part at the base of the thumb for instance) onto the screen, then release it and then press one of my arrows, the sprite moves in that direction for a few seconds, and then ACTION_UP is mysteriously triggered. The sprite stops and then if I release my finger and re-apply it to an arrow, the same thing happens. This goes on and on and eventually (randomly??) stops and everything work OK again. Test device & OS Google Nexus 10 Tablet running Jellybean 4.2.2 Code //Action upon which to switch actionMask = event.getActionMasked(); //Pointer Index of the currently touching pointer pointerIndex = event.getActionIndex(); //Number of pointers (for multi-touch) pointerCount = event.getPointerCount(); //ID of the pointer currently being processed (Multitouch) pointerID = event.getPointerId(pointerIndex); switch (actionMask){ //Primary pointer down case MotionEvent.ACTION_DOWN: { //if pressing left button then set moving left if (isLeftPressed(event.getX(), event.getY())){ renderer.setSpriteLeft(); } //if pressing right button then set moving right else if (isRightPressed(event.getX(), event.getY())){ renderer.setSpriteRight(); } //if pressing jump button then set sprite jumping else if (isJumpPressed(event.getX(),event.getY())){ renderer.setSpriteState('j', true); } break; }//End of case //Primary pointer up case MotionEvent.ACTION_UP:{ //When finger leaves the screen, stop sprite's horizontal movement renderer.setSpriteStopped(); break; }

  • Efficient mapping layout in 2D side-scroller, and collisions between character and the world

    - by Jack
    I haven't touched Visual Studio for a couple months now, but I was playing a game from the '90s toady and had an epiphany: I was looking for something what i didn't need, and I wasn't using what I knew correctly. One of those realizations was collision, so let me tell you a bit about my project that I was working on. The project's graphics looks like Mario or Dangerous Dave, etc., you get the idea - old-school pixels. So anyway I remember trying to think of something else than AABB for character form, but I couldn't think of anything. Perhaps I could get a suggestion for this? Another thing is the world - I don't want it to be just linear world, I want mountains, etc.. My idea is to use triangles, and no idea yet what to do if I want just part of the cube, say 3/4 or 2/4 or whatever. Hard-coding such things seems inefficient. P.S. I am not looking at the precision level offered by Box2D. Actually I remember trying to implement it at first, but I failed as my understanding of C++ wasn't advanced enough, as it'll be mentioned below. P.P.S. I am programming in C++, and I haven't done it for a couple months now. I have no means of testing it either, as my PC is broken down, and this one can barely run games from late '90s, not to speak about a compiler or a program with inefficient resource management... I am also not an expert (obviously), I don't even know if I can consider myself an average programmer. In short, I am simply curious about my thoughts and my past experience when programming the game. I may come back to it when my PC is fixed, I'm already filling a note about these things.
