• schema.org specification for generic pages or posts on a CMS

  - by NateWr

  I'm trying to determine the best possible schema.org type to declare for the content section in the template of a content management system, which will handle regular news posts for small, local hospitality businesses. The type should represent the content of that page, which is likely to be a wide range of things. The description for Article pretty strongly encourages its use to be limited to the articles of a publication. For purely semantic reasons, I'm not sure if Blog is appropriate in this case -- businesses won't be creating typical "blog" content but are more likely to be writing about upcoming events, special deals, awards, etc. Would Webpage be appropriate in this instance? Although I'm a fan of the schema.org concept, I frequently find myself unsure how broadly or narrowly I'm meant to infer the meaning of a type. In such cases, is it safe to use a high-level element, such as CreativeWork, or does this blunt the usefulness of the markup?

• 3D touch "Minority Report" style interface - what platform gets me there the fastest?

  - by Ross Braden

  I'm working on a project that requires touch interface, though the use case is desktop more than mobile. Want to start out platform agnostic, not a mobile app. There will be gridwork type of 3D objects and diagraming being represented - think AutoCAD or Minority Report. Want to build a prototype that will have hooks into a database to represent the data. Any advice on what tools to use both for the design and the development of the functionality is greatly appreciated. Thanks!

• How do I set a wine program (ex. Foxit Reader for Windows) as the default program?

  - by To Do

  I regularly annotate pdf files and unfortunately there is no good linux pdf reader that supports decent annotations. Evince has a very rudimentary and buggy annotation feature. So I'm stuck using a Windows viewer through wine. This works pretty well but, when I simply right-click a file (in this case a pdf), properties, open with and selected Foxit Reader, the Unity Launcher icon remained the wine icon instead of the application icon. Has anyone set a wine program as the default program for any file? Any ideas?

• DirectCompute information

  - by N0xus

  I've been trying to make use of the GPU as part of a project of mine. I've looked into both CUDA and OpenCL, but the lack of information showing you how to introduce these into a project is shocking. Even their dedicated forum groups are dead. So now, I'm looking into DirectCompute. From what I can tell, it's simply a new type of shader file that makes use of HLSL. My question is this, does my program (aside from being DirectX 10 / 11 ) need its structure changed? I mean, is it simply a case of creating the CS file, setting in the project like I would any other shader, and watch the magic happen? Any information on this would be appreciated.

• Javascript slider with fade

  - by tarmes

  I've been scouring the web for a slider that offers a particular effect, but I can't find one. I'm hoping that someone here will be able to help out... Specifically, I need a slider that will slide left and right through a series of HTML DIVs. However, I also need the old slide to fade out as it slides. This is because I don't what to have a visible frame around the the slider, so I don't want the old slide to be cropped against an invisible edge. It's hard to explain in words, so here's a graphic. In each case the green slide is entering the view, the red one is existing. Is possible, I'd like the slide to use CSS3 transitions where available for the smoothest possible effect. Has only ever come across such a beast?

• Compare a variable that can have numeric or string as value

  - by Tarun

  I have a variable named Seconds_Behind_Master from one of my scripts. The problem is that this variable can either have a numeric value or can also take a string NULL as its value. Now, when I try to execute this script in shell it gets executed but gives a warning like this: [: Illegal number: NULL I believe it is due to the fact that in this case the value is NULL but when it compares it with numeral value 60 it gives this warning. How can I rectify it? Here is the piece of code: Seconds_Behind_Master=$Show_Slave_Status | grep "Seconds_Behind_Master" | awk -F": " {' print $2 '} if [ "$Seconds_Behind_Master" -ge "60" ]; then echo "replication delayed greater than or equal to 60." else if [ "$Seconds_Behind_Master" = "NULL" ]; then echo "Delay is Null." fi fi

• How to handle jumping up a slope in a runner game?

  - by you786

  In an 2D endless runner, what should happen when the player is running "too fast" up a slope and jumps? For example, in a "normal" case: .O. . __..O_____ . / . / O/ _/ If he is moving to the right slowly enough, he will jump upwards and land on the flat part of the surface. However, if he is moving too fast, the jump will have no effect as his forward motion will bring him back in contact with the slope before he can get high enough to pass over it. When the speed is sufficiently high, there will effectively be no jump. _________ / .O/ O/ _/ Are there any known ways to solve this issue? I know it's physically correct*, but are there techniques that other games use to overcome this in a reasonable manner? As a last resort I'll have to just remove all slopes that are too slanted. *If you constrain the player to never jumping backwards.

• Is there a quick way to convert camera raw files to DNG?

  - by dericke

  Before I switched from Windows to Ubuntu for my daily computing, I used Adobe's Photoshop Lightroom for processing photos from my DSLR. Adobe made it really straightforward to convert from proprietary camera raw files (in my case, .NEF) to DNG. I haven't found any way to convert NEF to DNG in Ubuntu yet. Most photography programs do process NEFs to JPG/TIFF/PNG/etc., but I'm looking for a converter for archival purposes. Are there any tools available, either standalone or built into another app, that can losslessly convert from NEF to DNG?

• reliably restarting services using upstart or runit

  - by murtaza52

  I want to reliably restart my app and web server processes on crash. If I understand correctly, runit starts every service as a child process. If the child process crashes this sends a signal to the parent process which in turn respawns the service as a child. How does this work in the case of upstart. Does it also spawn a child process like runit? I am considering using runit for this. Is that needed, or is upstart good enough for this ? I am using nginx for my web server and gunicorn (python) for my app server.

• Preparing For TechEd

  - by Tim Murphy

  This being my first time going to TechEd and I want to make sure that I get the most out of it.  The first goal is to make sure that I get to the sessions that cover as many topics as possible.  This is important for me as a Solution Architect consultant specializing in Microsoft technologies.  To this end I have spent some time going through the sessions on the myTechEd site. The other reason for the trip is to connect with the Microsoft development community.  This includes both members of my local Midwest community and the global communities that I have only had online connections with.  Sharing the experience and getting a chance to exchange ideas with new and old friends is a great part of any convention. In any case, the time is getting close and I am looking forward to the trip. del.icio.us Tags: TechEd 2012,TechEd,community

• Sites with overlapping code-bases. Developing multiple sites with little changes

  - by Web Developer

  I have to develop 3 different sites video.com for hosting video audio.com for hosting audio docs.com for hosting docs. domain names for example only Almost 80% of the functionality is the same for all the three, with remaining 20% being completely different features... How do I handle this? How does sites like SO handle this? I am developing this in YII framework and was thinking of having these different features as modules but in this case the menu/code links in html code can become difficult.

• Is there a (free) reliable place to get statistics from sites, more reliable than Alexa, Quantcast, Compete?

  - by S.gfx

  I mean, seems there's no way. I am just asking in case someone knows of a recent new site being more accurate. I am aware of Alexa's, Compete and Quantcast inaccuracies and/or limited system/range of sites to get their stats. I also know about websitegrader perhaps being a little more accurate (although not sure if that's the data I am after). And read Seomoz tools are reliable. I am yet though looking for a free solution, a 'reliable' Alexa. And not a place depending on a toolbar installation, an easy to trick place, or one with stats way too off, or of a very limited range of sites. I am almost sure there's nothing new, but I wanted to be sure.

• Is it practically useful to decline GUI for a newbie in Ubuntu?

  - by Kifsif

  My Ubuntu is 12.04. I have just started learning Linux and Ubuntu in particular. To remember commands quicker, I'd like to decline GUI. But there are some problems. I don't know where installed programs are to launch them. For example, I have a pdf file. I know that there is a program to view such files. Should it be the case of GUI, I would just click on the pdf-file, and have a look that I use Document Viewer 3.4.0. Then I would like to launch Firefox Web Browser. Even if I know it is installed, how to find the file to be launched using just CLI is a mystery to me. Could you suggest me anything.

• Adding a 'network' USB printer

  - by AndrewK

  I have a HP Deskjet 1050a printer, hence the 'network' in the title. Its a bog standard USB home printer. I have it attached to my router (has a USB port in it). I have got it connected and working to with Win8 PC and also a MacBook Air. Can't seem to get it to add as a printer to my Xubuntu laptop(s). It doesn't get detected automatically (not an actual network printer) and i've tried multiple options to get it working. It seems to add it but when printing a test page its saying the printer isn't connected. Ping works fine so it can see it, just can't add it as a printer. With Win8 I had to create a port with the IP of the printer (192.168.1.253 in this case), is there an Ubuntu alternative to do this?

• What is the standard for naming variables and why?

  - by P.Brian.Mackey

  I'm going through some training on objective-c. The trainer suggests setting single character parameter names. The .NET developer in me is crying. Is this truly the convention? Why? For example, @interface Square : NSObject { int size; } -(void)setSize: (int)s; I've seen developers using underscores int _size to declar variables (I think people call the variable declared in @interface ivar for some unknown reason). Personally, I prefer to use descriptive names. E.G. @interface Square : NSObject { int Size; } -(void)setSize: (int)size; C, like C# is case sensitive. So why don't we use the same convention as .NET?

• Is it common in companies that non-techs are doing analyzes

  - by Kubi

  It's been 2 months since I started working at an international big consulting company. I like my colleagues personally but it's like a joke since my first day. Analysts (people who has no idea about the tech. background) are planning the workflow and functions. In my case, none of my friends here even wrote even a single line of html. When I say Html, I doubt if they know what I mean. But they are deciding about really key decisions in a web system implementation project. Is this always like this?

• What does backup procedures and troubleshooting guidelines mean for a system

  - by Podolski

  I am writing the documentation for a piece of software which I have made but I don't understand what it means in some aspects. It asks me to write about backup procedures but what exactly does this mean? Does this mean like backing up the database on another hosting service or something else entirely? I am dumbfounded by what troubleshooting guidelines are as well. If you have any idea what this could mean feel free to give your insight even if you aren't 100% sure in case it could spark what it means inside of me. Thanks.

• Will Ubuntu be releasing an update for Cedar Trail Processors?

  - by Alan

  There is a file available on the Intel web site with the file name "cdv-gfx-drivers-1.0.1_bee.tar.bz2" and a date of July 6, 2012. It can be found by searching the Intel Download Center for the filename or the string "Linux* PowerVR Graphics/Media Drivers". The download page links to the file, release notes and a link, Enabling hardware accelerated playback that takes one to a page containing links to two pdf documents titled "Enabling Hardware Accelerated Playback for Intel® AtomTM Processor N2000/D2000 Series", one for Ubuntu and one for Fedora. The instruction and release notes speak to working with kernel 3.1.0 and since I do not feel I have the skills, knowledge or training to do anything else but, follow the instructions to the "T", I am very reluctant to try anything on my freshly updated 3.2.0 kernel. I would much rather use a Ubuntu supported kernel that applies these drivers and doesn't break anything in the process. Is it a case where this is so new that Canonical has not yet included these drivers but, soon will do so?

• Showing "Failed" for a SharePoint 2010 Timer Job Status

  - by Damon

  I have been working with a bunch of custom timer jobs for last month.  Basically, I'm processing a bunch of SharePoint items from the timer job and since I don't want the job failing because of an error on one item, so I'm handing errors on an item-by-item basis and just continuing on with the next item.  The net result of this, I soon found, is that my timer job actually says it ran successfully even if every single item fails.  So I figured I would just set the "Failed" status on the timer job is anything went wrong so an administrator could see that not all was well. However, I quickly found that there is no way to set a timer job status.  If you want the status to show up as "Failed" then the only way to do it is to throw an exception.  In my case, I just used a flag to store whether or not an error had occurred, and if so the the timer job throws a an exception just before existing to let the status display correctly.

• Replace Android on HP Slate 21?

  - by user288626

  I want to replace Android with Ubuntu for Androids on my new HP Slate 21. As far as I known none has ever tried it yet and I would appreciate if Ask Ubuntu would help out here. Would I need to unlock & root first my machine? (In which case I will need a second machine plugged to my Slate...) Or can I just insert the bootable usb with the distribution I need and go from there as in a normal non-optical drive situation? Also where can I find the downloadable file/image of Ubuntu for Android as describe here? I see no link with the name on it.. Should I just download the normal dis and choose from options when installing it?

• deny-uncovered-http-methods in Servlet 3.1

  - by reza_rahman

  Servlet 3.1 is a relatively minor release included in Java EE 7. However, the Java EE foundational API still contains some very important changes. One such set of features are the security enhancements done in Servlet 3.1 such as the new deny-uncovered-http-methods option. Servlet 3.1 co-spec lead Shing Wai Chan outlines the use case for the feature and shows you how to use it in a recent code example driven post. You can also check out the official specification yourself or try things out with the newly released Java EE 7 SDK.

• I've totally missed the point of distributed vcs [closed]

  - by NimChimpsky

  I thought the major benefit of it was that each developers code gets stored within each others repository. My impression was that each developer has their working directory, their own repository, and then a copy of the other developers repository. Removing the need for central server, as you have as many backups as you have developers/repositories Turns out this is nto the case, and your code is only backed up (somewhere other than locally) when you push, the same as a commit in subversions. I am bit disappointed ... hopefully I will be pleasantly surprised when it handles merges better and there are less conflicts ?
