• Printing with Lacie Lightscribe requires root privileges

  - by James

  I have installed Lacie Lightscribe software on Ubuntu 12.04. Everything seems to be fine, the drive is detected, the proper media is detected, but when I click print I get the message "Printing Requires Root Privileges". I am the main (administrator) account on this computer, part of the sudo group and I cannot seem to find an answer to this dilemna in plain english. I've seen some apparently relevant posts which say things like "check whether the files /usr/4L/4L-gui and /usr/4L/4L-cli have any setuid-bits set. If so, remove them" but I need more detailed step-by-step instructions than that, please. Is there anyone who knows how to solve this?

• Static GitHub powered blog engine

  - by Daniel Cazzulino

  Blog engines were the new &quot;cool thing to write&quot; after the fever of writing a new DI framework was over. It was kinda like the new &quot;hello world++&quot; example. Almost every single engine uses a database of some sort to keep posts and comments. Almost every one is not leveraging the web as a consequence ;) I was intrigued by the possibilities that a flexible and general-purpose hosting solution like Github could offer for a static blog engine: basically keeping plain markdown/HTML/razor/WLW/whatever files that through a publish/build time process generate static files that pass for a &quot;blog engine&quot;. GitHub even supports custom domain names, so why not? Such an &quot;engine&quot; would have a number of benefits: Plain CSS styling Arbitrary JavaScript Leverage the web infrastructure (caching, CDNs, etc.) ...Read full article

• OpenID implementation - PHP, Javascript, MySQL

  - by Marc A.

  Hello, I've started doing some research on the technologies that I will need for my website. I'm trying to implement a really simple website with OpenID user registration. The website will store a block of text for each user. I imagine this means that I will need a database with: User ID Open ID url Data Having said that, I'm still having trouble deciding what I really need to do this. I know that I will need the following for the actual site: Javascript JQuery CSS But on the back end, I'm kind of lost at the moment. I've been looking at the OpenID-Selector, which is coded in Javascript. It seems like it's exactly what is used on this site. Will I actually need PHP? MySQL for the data and user registration? Thanks for the kickstart!

• CMS without templates

  - by Mark

  I am looking for a CMS where I can layout the page from scratch using HTML/PHP/CSS and simply enter code such as:- FOR EACH (listOfArticles) SORT mostRecent CATEGORY news LIMIT 5 <div class="articleTitle">{title}</div> <div class="arcielBody">{body}</div> END to get a list of the five most recent articles of a certain category in the relevant place. Does such a thing exist anymore? Unless my mind is playing tricks on me, the CMSs of five or ten years ago had this approach. I am thinking of MovableType and the now defunct CityDesk. It seems to me that CMSs these days have a 'templates first' approach. I.E. you must always choose a template before doing anything - which I find really painful. Learning how to design these structured templates also seems overly painful. So can anyone help me in my quest? Thank you, Mark

• Writing to a structured buffer with a compute shader (D3D11)

  - by Vertexwahn

  I have some problems writing to a structured buffer. First I create a structured buffer that is filled with float values beginning from 0 to 99. Afterwards a copy the structured buffer to a CPU accessible buffer is made to print the content of the structured buffer to the console. The output is as expected (Numbers 0 to 99 appear on the console). Afterwards I use a compute shader that should change the contents of the structured buffer: RWStructuredBuffer<float> Result : register( u0 ); [numthreads(1, 1, 1)] void CS_main( uint3 GroupId : SV_GroupID ) { Result[GroupId.x] = GroupId.x * 10; } But the compute shader does not change the contents of the structured buffer. The source code can be found here (main.cpp): https://bitbucket.org/Vertexwahn/cmakedemos/src/4abb067afd5781b87a553c4c720956668adca22a/D3D11ComputeShader/src/main.cpp?at=default FillCS.hlsl: https://bitbucket.org/Vertexwahn/cmakedemos/src/4abb067afd5781b87a553c4c720956668adca22a/D3D11ComputeShader/src/FillCS.hlsl?at=default

• Multithreading synchronization interview question: Find n words given m threads

  - by rplusg

  I came across this question: You are given a paragraph , which contain n number of words, you are given m threads. What you need to do is , each thread should print one word and give the control to next thread, this way each thread will keep on printing one word , in case last thread come, it should invoke the first thread. Printing will repeat until all the words are printed in paragraph. Finally all threads should exit gracefully. What kind of synchronization will use? I strongly feel we cannot take any advantage of threads here but interviewer is trying to understand my synchronization skills? No need of code, just put some thoughts. I will implement by myself.

• YouTube: How to Style an AngularJS App on the Device

  - by Geertjan

  I installed the Droid@Screen plugin into NetBeans IDE 8 so that you can see the Android device that I held in my hand while doing the demo below. The demo shows the usage of the Terminal window to create an Ionic Framework application (from "tabs", which is one of the cool templates that the framework provides), i.e., that means I can use AngularJS to create a Cordova application out of the box, with many mobile-oriented components available out of the box. Then I deploy the app to the Chrome browser on Android, which means I can interact with it in NetBeans, e.g., for CSS styling and JavaScript debugging. In this demo, I show how the background color of the deployed app can be changed live from NetBeans. After that, once I'm happy with the styling, I deploy the app again, but this time as a Cordova app, i.e., a hybrid HTML5 application, which means the app is packaged as a native app and deployed directly to the device from NetBeans. All of the above can be viewed here in about 4 minutes in this silent movie: Direct link to the (silent) movie: https://www.youtube.com/watch?v=isP5TNI3kYk

• Resize broswer window below 400px on OS X

  - by David

  Resizing Firefox windows (by dragging) works fine, up until the window is about 400 px wide, at which point the width of the web page content cease to follow the window with. I'm pretty sure it's not a CSS issue, and the same thing goes for Chrome and Safari as well (they won't even let me resize the window < 400 px wide). I can't understand where this limitation comes from. Is it a setting in the browser? A bug? A limitation of the OS?

• I studied electrical engineering. Can I work as a developer? [closed]

  - by FailedDev

  A while ago I finished my Msc in Electrical Engineering and started working as an engineering consultant where I mostly do development work. I am good at picking up languages/technologies tools. I have fiddled with C/C++/C#/perl/ant/bash/html/css etc. Although I have never had a complain for my work, rather the contrary, I just feel that some day, someone will ask me a real hard task which would maybe seem rather trivial for a computer scientist but hard for me. Should I read/do something to become a better developer. Should I pick up a book about design patterns or algorithms for example? Is this normal that I have this kind of "fear"? Sorry if this is the wrong place to post this question. Please notify me so I can close it if this is the case.

• What do you need to know to get a job as a web developer

  - by Alex Foster

  What do you need to know to at the very least get your foot in the door? We're assuming for someone who doesn't have a college degree (yet) but will eventually get one. My guess is html, css, javascript, and php, and photoshop and dreamweaver, and sql. And being familiar with using a web host to have sites live, like knowing how to use cpanel. It's probably a very inaccurate and narrow guess but that's what i think right now. I don't know exactly.

• Oversizing images to produce better looking pages?

  - by Joannes Vermorel

  In the past, improper image resizing used to be a big no-no of web design (not mentioning improper compression format). Hence, for years I have been sticking to the policy where images (PNG or JPG) are resized on the server to match the resolution pixel-wise they will have with the rendered page. Now, recently, I hastily designed a HTML draft with oversized images, using inline CSS style such as width:123px and height:123px to resize the images. To my (slight) surprise, the page turned out to look much better that way. Indeed, with better screen resolution, some people (like me), tend to browse with some level of zoom (aka 125% or even 150% zoom), otherwise fonts are just too small on-screen. Then, if the image is strictly sized, the enlarged image appears blurry (pixel interpolation effect), but if the image is oversized the results is much better. Obviously, oversizing images is not an acceptable pattern if your website is intended for mobile browsing, but is there case where it would be considered as acceptable? Especially if the extra page weight is small anyway.

• Mobile Web or Objective-C?

  Cameron Moll is worried about a future in which we’ll all write Objective-C for the iPhone OS instead of writing web standards for the mobile web.At one point in time, J2ME (now Java ME) and WAP were the starting points for a discussion on mobile strategy and the web. Then, for a brief period of time, you talked about HTML/CSS. Now, for a growing majority of mobile strategies that don’t require a global presence on widely varying devices, the discussion begins with iPhone.Emphasis mine. Strategy...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.

• More free geek-read.December SolidQ Journal is online

  - by Greg Low

  I'm really excited to see the last SolidQ Journal for this year out the door. It's our free online magazine. I've been wondering about the future of printed technical magazines for a long time. I doubt they have much of a future, as online publications become more prevalent and more timely. By the time a print magazine gets to you, it's such a long time since the author wrote the material that it's hard to even retain relevance in a fast moving world. That's why I'm so happy to have the format we...(read more)

• What is the best way to pass data into an API from a website?

  - by Chris Wakoksi

  My main objective is to create a User Interface in order to provision(change the status: activate, deactivate, or suspend) modems. I have received a SOAP developer's guide to the specific type of modem that helps out with the specific values that I need to pass into Iridium's WSDL but I cannot figure out how to do this from a webpage I have created using HTML/CSS, and PHP? I have been told by others that I need to know the portal. I have no idea what that means. I am a beginner programmer who has learned programming for this project. Any suggestions as to how to pass my data into the provisioning API?

• Pay for Graphic Designer vs Programmer

  - by FrankSinatra

  In a corporate web-design setup, who typically makes more per hour, the graphic designer or the programmer? By graphic designer, I mean somebody who builds mockups probably in photoshop, selects font-styles, colors, etc. Most things layout-wise are near pixel-perfect, but likely after the initial implementation by the programmer, there will be a lot of small changes directed by the graphic designer. By programmer, I mean somebody who is coding the CSS, the HTML, and light backend support, probably in PHP. The programmer will attempt to duplicate the mockups given the limitations of the medium, and consult with the graphic designer afterwards on what changes are tangible and which are not. Both probably have an undergraduate degree from a respected four-year institution.

• Optimizing data downloaded via 'link' media queries and asynchronous loading

  - by adam-asdf

  I have a website that tries to make sensible use of media queries and avoid 'expensive' CSS for users of mobile devices. My eventual goal is to make it 'mobile-first' but for now, since it is based on Twitter Bootstrap it isn't. I included some background images (Base64 encoded) and styles that would only apply to "full-size" browsers in a separate stylesheet loaded asynchronously via modernizr.load. In Firefox (but not webkit browsers) it makes it so that if you navigate away from the homepage and then return, the content (specifically, all those extras) 'blinks' when it finishes loading...or maybe I should say reloading. If, instead of using modernizr.load, I include that stylesheet via a link... in the head with a media query attribute will it prevent the data from being downloaded by non-matching browsers (mobile, based on screensize) that it is inapplicable to?
