  • Install postgresql. Why is initdb unavailable?

    - by Starkers
    I'm following these instructions, however I can only get to step 17.2. Despite installing postgresql successfully via the sudo apt-get install postgresql command, upon running initdb -D /usr/local/pgsql/data Ubuntu tells me that it 'initdb' isn't installed. The instructions tell me this command is installed by sudo apt-get install postgresql so what's going on? I can make initdb available by installing postgres-xc, but I think postgres-xc is just some weird third party rubbish, and it's not detailed in the instructions. Any ideas?

  • Remove packages to tranform ubuntu Desktop to Server?

    - by Azendale
    I have a VPS that has Ubuntu 11.10 on it. Unfortunately, only the 11.10 Desktop (not server) image was available as an image to install your VPS with. How can I remove the packages included in the Desktop install, and, if needed, install the packages that only the server install has? I've tried sudo apt-get remove ubuntu-desktop and then sudo apt-get autoremove. Unfortunately, that didn't work: it only removed 'libjudy-debian' (or something like that) which was installed from having 'miredo' installed at one point.

  • Quick run through of the WP7 Developer Tools January 2011

    - by mbcrump
    In case you haven’t heard the latest WP7 Developers Tool update was released yesterday and contains a few goodies. First you need to go and grab the bits here. You can install them in any order, but I installed the WindowsPhoneDeveloperResources_en-US_Patch1.msp first. Then the VS10-KB2486994-x86.exe. They install silently. In other words, you would need to check Programs and Features and look in Installed Updates to see if they installed successfully. Like the screenshot below: Once you get them installed you can try out a few new features. Like Copy and Paste. Just fire up your application and put a TextBox on it and Select the Text and you will have the option highlighted in red above the text. Once you select it you will have the option to paste it. (see red rectangle below). Another feature is the Windows Phone Capability Detection Tool – This tool detects the phone capabilities used by your application. This will prevent you from submitting an app to the marketplace that says it uses x feature but really does not. How do you use it? Well navigate out to either directory: %ProgramFiles%\Microsoft SDKs\Windows Phone\v7.0\Tools\CapDetect %ProgramFiles (x86)%\Microsoft SDKs\Windows Phone\v7.0\Tools\CapDetect and run the following command: CapabilityDetection.exe Rules.xml YOURWP7XAPFILEOUTPUTDIRECTORY So, in my example you will see my app only requires the ID_CAP_MICROPHONE. Let’s see what the WmAppManifest.xml says in our WP7 Project: Whoa! That’s a lot of extra stuff we don’t need. We can delete unused capabilities safely now. Some of the other fixes are: (Copied straight from Microsoft) Fixes a text selection bug in pivot and panorama controls. In applications that have pivot or panorama controls that contain text boxes, users can unintentionally change panes when trying to copy text. To prevent this problem, open your application, recompile it, and then resubmit it to the Windows Phone Marketplace. Windows Phone Connect Tool – Allows you to connect your phone to a PC when Zune® software is not running and debug applications that use media APIs. For more information, see How to: Use the Connect Tool. Updated Bing Maps Silverlight Control – Includes improvements to gesture performance when using Bing™ Maps Silverlight® Control. Windows Phone Developer Tools Fix allowing deployment of XAP files over 64 MB in size to physical phone devices for testing and debugging. That’s pretty much it.

  • Wireframing: A Day In the Life of UX Workshop at Oracle

    - by ultan o'broin
    The Oracle Applications User Experience team's Day in the Life (DITL) of User Experience (UX) event was run in Oracle's Redwood Shores HQ for Oracle Usability Advisory Board (OUAB) members. I was charged with putting together a wireframing session, together with Director of Financial Applications User Experience, Scott Robinson (@scottrobinson). Example of stunning new wireframing visuals we used on the DITL events. We put on a lively show, explaining the basics of wireframing, the concepts, what it is and isn't, considerations on wireframing tool choice, and then imparting some tips and best practices. But the real energy came when the OUAB customers and partners in the room were challenge to do some wireframing of their own. Wireframing is about bringing your business and product use cases to life in real UX visual terms, by creating a low-fidelity drawing to iterate and agree on in advance of prototyping and coding what is to be finally built and rolled out for users. All the best people wireframe. Leonardo da Vinci used "cartoons" on some great works, tracing outlines first and using red ochre or charcoal dropped through holes in the tracing parchment onto the canvas to outline the subject. (Image distributed under Wikimedia commons license) Wireframing an application's user experience design enables you to: Obtain stakeholder buy-in. Enable faster iteration of different designs. Determine the task flow navigation paths (in Oracle Fusion Applications navigation is linked with user roles). Develop a content strategy (readability, search engine optimization (SEO) of content, and so on) Lay out the pages, widgets, groups of features, and so on. Apply usability heuristics early (no replacement for usability testing, but a great way to do some heavy-lifting up front). Decide upstream which functional user experience design patterns to apply (out of the box solutions that expedite productivity). Assess which Oracle Application Development Framework (ADF) or equivalent technology components can be used (again, developer productivity is enhanced downstream). We ran a lively hands-on exercise where teams wireframed a choice of application scenarios using the time-honored tools of pen and paper. Scott worked the floor like a pro, pointing out great use of features, best practices, innovations, and making sure that the whole concept of wireframing, the gestalt, transferred. "We need more buttons!" The cry of the energized. Not quite. The winning wireframe session (online shopping scenario) from the Applications UX DITL event shown. Great fun, great energy, and great teamwork were evident in the room. Naturally, there were prizes for the best wireframe. Well, actually, prizes were handed out to the other attendees too! An exciting, slightly different aspect to delivery of this session made the wireframing event one of the highlights of the day. And definitely, something we will repeat again when we get the chance. Thanks to everyone who attended, contributed, and helped organize.

  • Master Data Management Update

    Oracle's Master Data Management suite has seen remarkable development progress in the past year and a half. Leveraging out-of-the-box integration to applications provided by Application Integration Architecture, the cost, risk and time it takes to implement an MDM solution has been cut in half. Oracle Applications are now 'MDM Aware', Data Quality tools have reached state-of-the-art status, and new hubs are coming on line. In this AppsCast, Pascal Laik, VP MDM Products discusses this progress, what it means for Oracle customers, and where we are going from here.

  • Mount a LUKS partition at boot

    - by Adam Matan
    Hi, I have installed an Ubuntu machine with two encrypted LUKS partitions: one for / and one for /home. I've reinstalled the machine to upgrade to 10.04. Again, the / is installed using LUKS, and I'm able to mount the /home using: mkdir /media/home sudo cryptsetup luksOpen /dev/sda2 home sudo mount -t ext3 /dev/mapper/home /media/home The problem is, this cryptfs mapper disappears after boot, so I putting the appropriate line in fstab fails. How do I set the cryptfs to prompt for password and unlock the drive at boot? Thanks, Adam

  • Some lenses not working in 12.04

    - by Jazz
    I have just started experimenting with extra lens in Unity. I installed some that I found listed in an AskUbuntu question. Some of them don't seem to work. The "Cooking" lens is supposed to show recipes, but I just get a blank result - nothing is found. I have another lens which I assume is the youtube lens I installed, that sits and searches forever when I switch to it, and even type a search into it.
