• How can I programmatically block user input for a given time?

  - by black_puppydog

  As a person working in computer science working offline to avoid facebook and thelike is not always (meaning hardly ever) possible for me since I mostly have to be online to work. I have tried leechblock and similar things but the problem becomes that at some point I start making systems for myself to hack, which is kind of pointless if oyu have root. I would very much like to try out the method described here. (Short version: reboot your PC every time finish a task or get bored with it) Unlike for the author of this blog my work is mainly done not in screen sessions but in IDEs ans other not-so-fast-to-start-up stuff, meaning a full reboot including loading all my programs will take its time. So, the question is: How can I block all user input and preferrably blank the screen for a given amount of time? The idea would then be to have a keyboard shortcut to activate the script/program (which would probably also have to have root i guess?)

• Installer doesn't recognise windows 7 install

  - by SirWaffleRaptor

  I will start off saying I searched a bit for this problem with little success. You see, I am an utmost noob when it comes to Ubuntu and Linux based OS (hence why I want to install it and discover it) and the thread I found were too specific for me to do anything with. Therefore, if you find a thread that is noob-friendly and answers my question, please link it below or please try to answer as simply as possible :) The problem: I want to install Ubuntu 12.04 LTS 64 bit alongside Windows 7 on my main hard drive (to get the choice which one to start when booting). Pop the CD in, reboot and get to the installer screen. I know I'm supposed to have 3 options, but I'm only given the option to erase my hard drive or "do something else". Therefore, my question is: how do I make Ubuntu recognise Windows 7, so it may install alongside it?

• game is playing but broken graphics

  - by mewanttux

  I installed Steam on Lubuntu and wanted to play dota2 (it has source engine) and it sayed i need a 3dts driver or something but i installed it alredy. I can start dota now, but when i start a game it is not... displaying correctly. For example when i pick a hero the 3d modell is covered in some kind of a lasershow and the map...... i looked around a bit think it is because of the drivers and i should have mesa 9. Steam can show the system specs and it says that i have nouveau Gallium 0.4 on NVAA as driver and 3.0 Mesa 10.0.0-devel (git-1100093 saucy-oibaf-ppa) as driverversion and OpenGL 3.0 i am a noob on linux and need step by step guides please

• Mass audio encoder

  - by bessman

  I have a few thousand FLAC files which I would like to transcode to OGG Vorbis, but I can't find any suitable tools for the job. To name a few I have tried so far and why they are unsuitable: oggenc is single-threaded and would require me to automate it myself, mencoder requires the input to also contain video, and abcde assumes the input is a CD. The ideal tool should be multi-threaded, and support inputing multiple files located in different directories simultaneously. CLI or GUI makes no matter. Does such a tool exist?

• transfer Thunderbird (17) Profile on Win7 to Ubuntu 12.04

  - by William Curran

  I want to transfer Thunderbird Profile on Win7 to thunderbird (17) Ubuntu 12.04. I already copied the profile folder from Windows to Ubuntu and modified progile.ini on the ubuntu machine to include [Profile] Name=Bill IsRelative=1 Path=(the name of the transfered profile folder) I think the problem is that the Win. TB profile content (files and folder structure) look VERY different that the that of the unbuntu TB profile's that was created on installation. The Ubuntu install is new where as the Win TB has undergone many updates. Seems the system for profile storage has changed drastically. I tried to start TB in safe mode but could't get the path correct to start TB in the terminal with the -safe-mode switch. What can I do? Bill

• Ubuntu 10.10 booting but not rebooting from external USB hard drive, what could be the problem?

  - by user8276

  I have a Dell Inspiron 6400 laptop with a dead internal hard drive controller. It boots perfectly from CD or USB. I therefore removed the internal hard drive and installed Ubuntu 10.10 Maverick onto an external USB hard drive. It boots and runs perfectly when doing a "cold start" of the PC. However, when I choose restart/reboot in the Ubuntu menu (e.g. after an update), I get this error message from the BIOS: "No bootable devices, strike f1 to retry boot, f2 for setup utility, press f5 to run onboard diagnostics". I can make the system boot again by pressing f2 or f5 and exiting the utility without having done anything. Or, I can simply power off the system and do a new "cold start". Does anyone know the likely reason for this problem and how to fix it. It is not a big issue but an annoyance that I would like to fix if possible.

• Learning PHP MySQL [closed]

  - by Keith Groben

  I've been a designer for several year now. I'm now very interested in learning PHP, MySQL. I've read through W3Schools already and it helped me become familiar. I now want to know where I could go to start building some simple database and php applications so I could be come familiar with coding and start to improve. I think hands on application is the best way to learn. Since I'm a beginner, much of what I've found so far is sort of advanced to me.

• Algorithm for optimal combination of two variables

  - by AlanChavez

  I'm looking for an algorithm that would be able to determine the optimal combination of two variables, but I'm not sure where to start looking. For example, if I have 10,000 rows in a database and each row contains price, and square feet is there any algorithm out there that will be able to determine what combination of price and sq ft is optimal. I know this is vague, but I assume is along the lines of Fuzzy logic and fuzzy sets, but I'm not sure and I'd like to start digging in the right field to see if I can come up with something that solves my problem.

• Why Your Abstract Wasn't Selected

  - by AllenMWhite

  We're anxiously waiting to hear from PASS which sessions were selected for the 2014 Summit in November. It's a big job to go through the hundreds of submissions and pick the sessions that will appeal to the people who will be paying over $1,000 to attend this annual event. As I am also waiting to hear the results, I saw this article addressed to actors who didn't get cast for the part they worked so hard to audition for, and it seemed appropriate to address the same issues for would-be Summit speakers....(read more)

• Telerik OpenAccess ORM and the XML Metadata Source

  We all know that Telerik OpenAccess ORM has a completely new face with the Q1 2010 release so it is about time to start blogging about some of the features and improvements that the new Visual Designer brought along.  Today I will talk about one of the most notable changes in the new version of OpenAccess ORM and that is the XML only mapping. You all know that so far with the previous versions of the product the mapping information was defined by a mix of XML configuration files and CLR attributes. After a lot of customer feedback and thorough thought we decided to make the XML and the attributes as two separate and self-contained sources of metadata information about your model. You can choose one based on your personal preferences. I will start with a brief overview over the new XML mapping definition. Unlike previous versions, where all ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Gnome/X logs off immediately after login -- which logfiles are relevant?

  - by joebuntu

  I've been tinkering with fingerprint-gui as well as X/xrandr resolution settings. When I start my machine, it boots up normally. As soon as X and gnome have finished starting, it logs me off automatically and brings me back to the gdm login prompt with the user list. Then I am, however, able to log in using "Ubuntu Desktop Fail-safe". I've checked the list of start-up applications, but everything seems fine there. I can't yet put my finger on what exactly might be responsible for this: X, gnome or some messed up pam.d settings. So far I've checked /var/logs/X11/xorg.0.log, /var/logs/auth.log and ~/.xsession-errors. In addition, I don't quite seem to understand the "interplay" between X, GDM, GNOME, GNOME-policykit, PAM.d and all that. Are there any other relevant log files that could point me to what's broken? Specs: Ubuntu 10.10 Maverick Meerkat IBM/Lenovo Thinkpad R60, ATI Radeon x1400 Mobility all updates installed Linux User 1 year+,

• Why would you use data structures (ie Binary Trees, Linked Lists) in your jobs/side projects? [closed]

  - by Chris2021

  It seems to me that, for everyday use, more primitive data structures like arrays get the job done just as well as a binary tree would. My question is how common is to use these structures when writing code for projects at work or projects that you pursue in your free time? I understand the better insertion time/deletion time/sorting time for certain structures but would that really matter that much if you were working with a relatively small amount of data?

• Visual Studio 2010 HTML5

  - by Renso

  Goal: Enabling HTML5 validation and  IntelliSense for Visual Studio 2010. By default it is set to XHTML 1.1. HTML5 support only came included with SP1 of Visual Studio 2010. However since HTML5 is not an official standard as yet and some of the 30 new elements are not suported in all browsers, so only a subset of the entire HTML5 specification is supported; support for both intellisense and validation for HTML5 with SP1. How to: After installing SP1 you have to tell Visual Studio to start using the HTML5 schema. Go to Tools -> Options, and then select Text Editor -> HTML -> Validation. Select HTML5 or XHTML5 as the target schema. So start building or converting older Visual Studio projects to HTML5 and CSS3 web applications.

• How do I script to open a set of programs each on specific desktop?

  - by Jahn

  I looked around for a while and could not figure out the answer to my following problem: I have a setup of six desktops on Ubuntu 12.04 with Unity. On start up, every morning, I go through a routine of opening the same five or six programs. I open each on a specific desktop. I would like to have this automated. Is there a way to script or configure this? Additional question: To further complicate the matter, I am running two screens in twin view mode. I actually need to start each program on a specific screen, preferably in full screen. Thanks in advance, Jahn

• Standalone URL 301 Redirect Manager [on hold]

  I'm looking for a script with a simple interface that helps me manage a large list of 301 redirects of the form: http://example.com/short ---> http://example.com/long-and-descriptive For example the following Wordpress plugin does this job, but it seems excessive to install Wordpress just for this one simple functionality. It looks like my question is similar to this closed question, but hopefully rephrased in such a way that makes it more relevant and "constructive".

• In what order do people build websites?

  - by Corey

  For a website, you need to have an idea, you need to have a design and you need to have data, events and output, right? Whether it be a blog, web app, Q&A site, search engine... Anyway, that is only slightly related to my question. My question is, when designing a website, providing I know the purpose, what should I start with? Should I start with the CSS, design and look&feel using dummy data first, or should I program in the logic, events and output, and style it later? What is the design process of most websites that are built from the ground up?

• Application versioning

  - by Mathew

  Haven't find similar issue so sorry if thats a duplicate. I'm about to start a migration of an already existing project from one web container version to the another. Currently, the application version is 2.2.5. Business requirement is to deliver a 3.0 version by the end of the year. Additional constraint is to release a working, stable version by the end of Q3. We are about to work in 2-weeks sprints and I'm wondering how can I approach the problem? I was thinking about releasing 2.3 by the end of Q2, then immediately promoting it as 3.0-a1, work on alphas (3.0-a2, 3.0-a3, ...) till the end of Q3, to start with 3.0-b1 in the early Q4 and finally release 3.0 around December. I don't feel comfortable saying that the application is already in 3.0 state in July, but I can't see other options. If you find some book chapters/blogs or your personal experience interesting please share your opinion.

• How to model a system to help my team grasp the project's bigger picture? [closed]

  - by user1796528

  According to the software engineering point of view, I should model the system to make it easier for other people to understand well what they work on. To do so, I have used the Dia drawing program. But, after having used Dia for some time, I find that it falls short in helping me to correctly and efficiently model my project. How do you usually tackle this problem (modelling a project in the large) and what tools would you recommend for the job, and why?

• reading parameters and files on browser, looking how to execute on server

  - by jbcolmenares

  I have a site done in Rails, which uses javascript to load files and generate forms for the user to input certain information. Those files and parameters are then to be used in a fortran code on the server. When the UI was on the server (using Qt), I would create a parameters file and execute the fortran code using threads so I wouldn't block the computer. Now that is web-based, I need to make the server and browser talk. What's the procedure for that? where should I start looking? I'm already using rails + javascript. I need that extra tool to do the talking, and no idea where to start.
