  • When to learn the command line version of a programming tool ?

    - by explorest
    Almost every programming tool has a command line version; many of which also have a gui version. It takes a lot of time and memorization effort to learn the different commands and various options/switches om the command line version. So I have a couple of questions (which are not necessarily mutually exclusive): 1) When would you bother learning/memorizing the commands in the command line version of a tool which also comes in a gui version ? 2) What tools should I learn the command line version of ? .... compilers ? version control system ? etc, etc

  • Logitech Microphone (AK5370) inaudible volume

    - by Iain Lane
    I bought this microphone from Amazon last week. It's detected just fine in 12.10. I can see it in the sound preferences. The problem is that the volume is so low as to be inaudible, even when turned up to maximum in this dialog. It is working, as I can see that the meter responds to noise, but it's just too low. alsamixer's control is the same, so that doesn't help. I tried messing around in pulseaudio too, but to no avail. In lsusb it's Bus 002 Device 004: ID 0556:0001 Asahi Kasei Microsystems Co., Ltd AK5370 I/F A/D Converter.

  • What is the most serious limitation of Unity?

    - by ashes999
    Having read this heated question about Unity vs. UDK vs. ID something, I'm curious to know: what the repeatedly-hit, most crippling limitation(s) of Unity? In order to keep this question non-subjective, again, I'm talking about the top repeated offender(s) of Unity are. This is something that, as a Unity user, you really wish someone had told you about before you started using it. I have heard from someone that Unity does not deal well with version control, since it generates a lot of binary files (which are un-diffable). This, to me, is not really crippling as I work alone. Thoughts?

  • Selecting Dynamic ID JQuery [migrated]

    - by Vedran Wex Maricevic
    I need to select dynamic id using JQuery, and once I select it then I need to do some action on it. This is the HTML that I have: <input id="content_photos_attributes_1355755712119_image" name="content[photos_attributes][1355755712119][image]" size="30" type="file"> Please note the id value, text is always the same however the number changes (I do not have control over that change). What I need to do is to create on click for that element. This is what I got so far, and it is not working. <script type="text/javascript"> jQuery.noConflict(); jQuery("input[id *= 'content_photos_attributes_']").click(function() { alert("Image deletion is clicked"); }); </script> It really makes no difference whether I select that element by ID or by its name.

  • How can I make refactoring a priority for my team?

    - by Joseph Garland
    The codebase I work with daily has no automated tests, inconsistent naming and tons of comments like "Why is this here?", "Not sure if this is needed" or "This method isn't named right" and the code is littered with "Changelogs" despite the fact we use source control. Suffice it to say, our codebase could use refactoring. We always have tasks to fix bugs or add new features, so no time is put aside to refactor code to be better and more modular, and it doesn't seem to be a high priority. How can I demonstrate the value of refactoring such that it gets added to our task lists? Is it worth it to just refactor as I go, asking for forgiveness rather than permission?

  • What You Said: How Do You Set Reminders?

    - by Jason Fitzpatrick
    Earlier this week we asked you to share your favorite tricks for staying on top of your tasks with timely reminders. Now we’re back to highlight some great reader tips (including a bit of software older than some of our readers). Most of us have to-do lists longer than we can do in a given day (or week!) and a constantly changing set of demands and next-actions. Having a timely and effective reminder system is the difference between dropping the ball and getting things done; how exactly that reminder system plays out, however, varied greatly from reader to reader. OJMDC sticks with analog reminders: Sticky notes in the middle of my monitor and in my wallet. I’ve tried my phone apps but I typically disregard them. HTG Explains: Is UPnP a Security Risk?

  • Is there any way to simulate a slow connection between my server and an iPad (without installing anything on the server)?

    - by Clay Nichols
    Some of our webapp users have difficulty on slower connections. I"m trying to get a better idea of what that "speed barrier is" so I'd like to be able to test a variety of connection speeds. I've found ways to do this on Windows but no on the iPad, so I'm looking more for some sort of proxy service that'll work with any device (not running ON that device) I did find an article about using the CharlesProxy and providing a connection to another device, but I was hoping for something simpler (need not be free) Constraints * We are on a shared server so we can't install anything and we are limited in our control over that server. * I'd like to test an iPad, Android Tablet, Windows PC.

  • Android device connects to my computer, but doesn't play audio over Bluetooth

    - by bi99l35
    I turn on Bluetooth on both my devices and open up Music on my Android. I select a song to play, press the menu button, and tap "Via Bluetooth": I tap on my computer in the "Bluetooth Device Picker": Then it says, under the name of my computer: Connected to media audio Now I should technically be able to play music through my computer, since it "Just Worked" in Kubuntu with Blueman. But nope, something must be up with PulseAudio, because I hear no sound from my computer (I'm running Xubuntu 12.04). The reason I say this is that the devices list in Blueman shows indication of data transfer and it says it's connected, but in the PulseAudio Volume Control has no indication of my Bluetooth device (or Blueman) playing audio.

  • Running Mixed Physical and Virtual Exalogic Elastic Cloud Software Versions in an Exalogic Rack is now Supported

    - by csoto
    Although it was not supported on older versions, now as of EECS 2.0.6, an Exalogic rack can be configured in a mixed-mode: half virtual and half physical Linux: Flexibility to have physical and virtual environments on same rack. For example, production on physical and test/dev on virtual. Exalogic Control manages the virtual compute nodes on the rack. Physical compute nodes are managed manually (including PKeys). Option to change full physical to hybrid and hybrid to full virtual rack. User has an option to choose either the top or bottom nodes for physical or virtual deployment. For further information about how the compute nodes can be split up on the rack (into bottom or top half) to run either Oracle Virtual Server (OVS "hypervisor") or Oracle Linux, please take a look at MOS Note 1536945.1. Note: Solaris is not yet supported in the mixed configuration.

  • Problems using PHP on a Plesk Windows dedicated server

    - by wpsmdouble
    I'm having a few issues with my dedicated Windows server that has a Plesk panel: 1.) I can't send e-mail via PHP's mail() function, it always returns the following error: SMTP server response: 550 Requested action not taken: mailbox unavailable or not local Which setting should I alter in order to enable sending mail? 2.) The exec() and passthru() PHP functions don't work; their outputs are blank even when I try to run simple commands such as dir. Is there an option that I can toggle in the control panel to enable this functionality?

  • Template standard controls for an entirely new look and feel

    - by T
    This is the  Ineta Live player without the O’Data Feed.  It is a good example of taking the plain Media Player provided with the Encoder install and re-templating it to make it your own.  It also has a custom scrub control that is added in.  I generally put my tempates in a separate resource file.  On this project, I discovered that I had to include the template at the document level because I needed the ability to attach some code behind to fire change state behaviors.  I could not use the blend xaml behaviors for change state inside the template because the template can’ determine the TargetObject.   Version 1.01 – 6/10/09 (wow how did a week slip by)

  • Share buttons vs sharer urls

    - by TeeOh
    As some people might know, adding share buttons from Facebook and Twitter can cause a page to slow down. I've seen many sites pass on the common iframe implementations that these sites offer and simply create icons that link to a sharer url for better control of page performance. http://www.facebook.com/sharer/sharer.php?u=http%3A%2F%2Fwww.cnn.com%2F&t=CNN%26s+website%27 However, I've also read that Facebook is dropping support for these links. For example, this link now redirects to the Like Button. http://www.facebook.com/facebook-widgets/share.php Here is an article noting that Facebook is deprecating/has deprecated it's share functionality and is sticking with the Like button. http://www.barbariangroup.com/posts/7544-the_facebook_share_button_has_been_deprecated_called_it I'm assuming this is the same for the sharing url. If the sharer url is no longer a reliable option, what other methods are there besides using 3rd party widgets (like Addthis)?

  • Two "subdomains" crossing search results

    - by LuckySpoon
    My question relates to two websites, each of which is a "Calvary Christian College", however in two totally different locations and unrelated to each other entirely (except by name, and domain). All schools in the state are issued a .qld.edu.au, in this case calvary.qld.edu.au and calvarycc.qld.edu.au. Now what's interesting is that these domains are crossing each other in sitelinks for searches such as "calvary christian college townsville" (if you check the sitelinks 2/6 are to a different domain). I've put a demotion in for this ages ago (we control calvary.qld.edu.au), however we're seeing no change on the results page. I have been able to get the owners of calvarycc.qld.edu.au to submit demotions for our domain, which should go in sometime this week. What can we do to tell Google that these websites are not interchangeable, despite both appearing as "subdomains" of qld.edu.au. We can possibly open channels of communication with the administrators of qld.edu.au but will need to tell them what we need to change, and at this point I'm out of ideas.

  • Need an engine for MMO mockup

    - by Kayle
    What I don't need is an MMORPG engine, at the moment. What I do need is a flexible easy-to-use engine that I can make a mock-up with. I don't need support for more than 10 players in an instance, so any multiplayer platform is probably fine. I need an engine with which I can create the following core features: Waves of simple AI enemies that have specific objectives (move to point A, destroy target, move to point B). The units present can be between 50-200 in number. An over-the-shoulder view and the ability to control a team of 3 (like Mass Effect or the latest Dragon Age) Functioning inventory system Right now, all I can really think of is Unreal or Source. Any other suggestions? Again, this is a proving mock-up, not an actual MMO. I'm not terribly worried about the visual aspects as we just want to test mechanics. Note: Can write some scripts in Python, Ruby, or Lua, if necessary.

  • Technology/Techniques to prevent offensive images on a website

    - by Andreas Siegers
    I am planing to build a website which one of its main features is the usage of pictures. I was wondering what existing techniques are used to prevent offensive pictures (i.e pornography) to get loaded by users. i.e What does Facebook or Pinterest use? As well I would like to know what your recommendations would be to control offensive pictures to get uploaded to the site (OpenSource tools maybe..) Taking into consideration this is a personal project and will be developed with a very small budget. Thank you

  • TFS 2010 and Expanding Possibilities

    - by ssmantha
    My organization is migrating to the new Team Foundation Server 2010, and we all are busy experimenting with ALM features. I find it very exciting and I foresee quite a lot of possibilities for TFS 2010 getting integrated with the Dynamics product line. I hope most of us know about the Version Control capabilities. However, I see a strong possibilities of having Team Builds and other automations, thanks to the technologies like workflow foundation in .net which is now being actively used in various TFS scenarios.   Lots of experiments so there is more to come!!

  • Avoiding null in a controller

    - by Kevin Burke
    I'm trying to work through how to write this code. def get(params): """ Fetch a user's details, or 404 """ user = User.fetch_by_id(params['id']) if not user: abort(404) # Render some template for the user... What's the best way to handle the case where the lookup fails? One principle says you should avoid returning null values from functions. These lead to mistakes and AttributeErrors etc. later on in the file. Another idea is to have fetch_by_id raise a ValueError or similar if no user exists with that id. However there's a general principle that you shouldn't use exceptions for control flow, either, which doesn't help much. What could be done better in this case?

  • What to do when there are no logical user stories but separate development tasks?

    - by Alex. S.
    We need to generate a release in 3 weeks, and for the planning we are doing today we don't have coherent logical user stories from the backlog tasks. Is valid to match say each development task is equivalent to an user story? Methodologically what is the correct way of handling this?, because anyway we are going to have standup meetings and we are going to control the progress of the project against those development tasks. For example, we have things like: . Adapt ETL to process numeric lists . Adjust licensing component . Remove DTC and so on. So, for the planning poker and iteration planning is valid to use those tasks? if not, what is the alternative?

  • Getting Started with ADF Mobile Sample Apps

    - by Denis T
    Getting Started with ADF Mobile Sample Apps   Installation Steps Install JDeveloper 11.1.2.3.0 from Oracle Technology Network After installing JDeveloper, go to Help menu and select "Check For Updates" and find the ADF Mobile extension and install this. It will require you restart JDeveloper For iOS development, be on a Mac and have Xcode installed. (Currently only Xcode 4.4 is officially supported. Xcode 4.5 support is coming soon) For Android development, have the Android SDK installed. In the JDeveloper Tools menu, select "Preferences". In the Preferences dialog, select ADF Mobile. You can expand it to select configure your Platform preferences for things like the location of Xcode and the Android SDK. In your /jdeveloper/jdev/extensions/oracle.adf.mobile/Samples folder you will find a PublicSamples.zip. Unzip this into the Samples folder so you have all the projects ready to go. Open each of the sample application's .JWS file to open the corresponding workspace. Then from the "Application" menu, select "Deploy" and then select the deployment profile for the platform you wish to deploy to. Try deploying to the simulator/emulator on each platform first because it won't require signing. Note: If you wish to deploy to the Android emulator, it must be running before you start the deployment.   Sample Application Details   Recommended Order of Use Application Name Description 1 HelloWorld The "hello world" application for ADF Mobile, which demonstrates the basic structure of the framework. This basic application has a single application feature that is implemented with a local HTML file. Use this application to ascertain that the development environment is set up correctly to compile and deploy an application. See also Section 4.2.2, "What Happens When You Create an ADF Mobile Application." 2 CompGallery This application is meant to be a runtime application and not necessarily to review the code, though that is available. It serves as an introduction to the ADF Mobile AMX UI components by demonstrating all of these components. Using this application, you can change the attributes of these components at runtime and see the effects of those changes in real time without recompiling and redeploying the application after each change. See generally Chapter 8, "Creating ADF Mobile AMX User Interface." 3 LayoutDemo This application demonstrates the user interface layout and shows how to create the various list and button styles that are commonly used in mobile applications. It also demonstrates how to create the action sheet style of a popup component and how to use various chart and gauge components. See Section 8.3, "Creating and Using UI Components" and Section 8.5, "Providing Data Visualization." Note: This application must be opened from the Samples directory or the Default springboard option must be cleared in the Applications page of the adfmf-application.xml overview editor, then selected again. 4 JavaDemo This application demonstrates how to bind the user interface to Java beans. It also demonstrates how to invoke EL bindings from the Java layer using the supplied utility classes. See also Section 8.10, "Using Event Listeners" and Section 9.2, "Understanding EL Support." 5 Navigation This application demonstrates the various navigation techniques in ADF Mobile, including bounded task flows and routers. It also demonstrates the various page transitions. See also Section 7.2, "Creating Task Flows." Note: This application must be opened from the Samples directory or the Default springboard option must be cleared in the Applications page of the adfmf-application.xml overview editor, then selected again. 6 LifecycleEvents This application implements lifecycle event handlers on the ADF Mobile application itself and its embedded application features. This application shows you where to insert code to enable the applications to perform their own logic at certain points in the lifecycle. See also Section 5.6, "About Lifecycle Event Listeners." Note: iOS, the LifecycleEvents sample application logs data to the Console application, located at Applications-Utilities-Console application. 7 DeviceDemo This application shows you how to use the DeviceFeatures data control to expose such device features as geolocation, e-mail, SMS, and contacts, as well as how to query the device for its properties. See also Section 9.5, "Using the DeviceFeatures Data Control." Note: You must also run this application on an actual device because SMS and some of the device properties do not function on an iOS simulator or Android emulator. 8 GestureDemo This application demonstrates how gestures can be implemented and used in ADF Mobile applications. See also Section 8.4, "Enabling Gestures." 9 StockTracker This application demonstrates how data change events use Java to enable data changes to be reflected in the user interface. It also has a variety of layout use cases, gestures and basic mobile patterns. See also Section 9.7, "Data Change Events."

  • Adding PPA on install

    - by trampster
    I have a app I am packaging for ubuntu. I don't like the idea that if included in the ubuntu repositories I will have no control over updating that application. I don't want my users stuck on an out dated version for up to 6 months. I also do not want my users to have to manually add a PPA themselves to get updates as the target user will not have the technical know how to do this. Is it OK to have my .deb add a PPA on install. So that I can roll out stable updates to my ubuntu users.

  • Starting application in same window with XFCE4 Terminal and i3

    - by Luke
    Since recently I'm enjoying the i3 tiled window manager. I did install the XFCE4 Terminal since it gives greater control over my terminal look and feel however but I have noticed an issue with starting GUI based applications. When I execute a GUI based application I want it take over the current terminal window. To do this I use exec, as in: exec eclipse This will open a new window and leave the terminal I started the application in open as well. In normal circumstances this is not much of a problem since I can easily do an Alt-W on the GUI app's window. However, for some applications, like a file manager, it is necessary to open in the same window. How can I make GUI application open in the same window rather than opening a new one?
