• Screensaver + lock double login problem after Maverick upgrade

  - by dr Hannibal Lecter

  Just found something strange after updating from 10.04 to 10.10. I've set up my screensaver to lock the account when activated. When I log back in, I see my desktop for a second and then the screensaver starts again and I have to re-login. I checked my process list in gnome system monitor, and I have two gnome-screensaver processes(!?), one started as /usr/bin/gnome-screensaver and other simply as gnome-screensaver. And no, I did not start one manually. Where do I look for a way to switch off one of those (supposing that's the problem)? I did not find anything in my startup applications.

• Trial/Free & Full Version VS. Free App + In-app billing?

  - by SERPRO

  I'm just wondering what would be the best strategy to publish an application on the Android Market. If you have a free and paid version you have two codes to update (I know it will be 99% the same but still) and besides all the popular paid apps are quite easy to find for "free" in "alternative" markets. Also if you have any stored data in the trial/free version you lose it when you buy the full version.. On the other hand if you put a free application but inside you allow the user to unlock options (remove ads/more settings/etc...) you only have to worry about one code. I don't know the drawbacks of that strategy and how easy/hard is to hack that to get all the options for "free".

• Google page events monitoring and analysis

  - by Homunculus Reticulli

  I have read the Google page event documentation, but I am not sure I understand it correctly. I am new to Google analytics, and I have two questions: Once I have google analytics enabled for my site (i.e. I have inserted the tracking code in my pages etc), do I need to set anything else up (at the Google end - i.e. in my Google analytics account) It is not clear to me how the event data particularly, relating to how the data can be aggregated and analyzed. For instance, if I want to track an event under category category for click action action, I will use the following code snippet: <a href="some-uri.htm" onclick="_gaq.push(['_trackEvent', 'category', 'action', 'label']);">Do Something</a> For the sake of simplicity, lets say I am interested in monitoring click events in my header and footer, and I want to find which pages the header and or footer is clicked most often. How would I set things up so that I can analyze the header/footer clicks aggregated at the page level?

• Website with sections in Drupal?

  - by Matt Hampel

  What is the best way to create a website with sections in Drupal? Users need to be able to add, remove, and nest pages fairly easily. Pages added to a section should have an appropriate URL, like "/[section name]/[page title]". This seems like a straightforward task, but I can't find the right combination of tools to do it. Subsite comes close, but for some odd reason, doesn't set up the correct content paths. The closest I got was creating a book for each subsection, but that feels like I'm using the wrong tool for the job. Edited with my solution: I used organic groups with pathauto. I set pathauto so that pages in groups had URLs that were of the form [group path]/[page title].

• 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?

• Sync csv file using nodejs

  - by Amit Dugar

  There is a remote csv file that gets updated every second or so. I need to download it(on a Windows machine) ONCE and always sync local file with the remote one. Obviously, downloading the whole file every time is not an option. I need to download only the changes.(something like rsync, rdiff-backup) I searched quite a bit but could not find how I can do this. I am sort of new to nodejs and am using this app as an opportunity to expand my nodejs skills. Also, I am planning to use nodejs and to package it using node-webkit(https://github.com/rogerwang/node-webkit)

• Cloud storage that works with rsnapshot?

  - by humbledude

  I’ve started using rsnapshot as my backup system for my home PC. I really like the idea of hard links and how they are handled. But I can’t find the best workflow. Currently I keep my snapshots on the same partition and will copy the newest snapshot to a pen-drive at the end of the week. Cloud storage is what I’m looking for. Dropbox doesn’t fit my needs, because there is no way to make Dropbox respect hard links — all snapshots are treated as full snapshots. Renting a server is pretty expensive, so my question is, are there better alternatives for backup in the cloud? I would like to benefit from hard links and send only incremental backups, just like I do with my local host.

• 12.04 scanner works fine as super-user but is not recognised as a normal user

  - by Eugénio Outeiro

  I have an all-in-one printer Epson SX130, wich I have just tried to install. I got the printer working with no problem, but I couldn't set the scanner up. I have had another all-in-one printer before (Brother DCP-125C), and had just the same problem, so I decided to try the same trick I used to do then, running the scanning program as super-user: $sudo simple-scan and $ sudo xsane Once again, it worked just fine, and I could use the scanner. Anyhow, this solution is a little annoying, because I also have to change the permissions to the files I get scanning like this. I have been searching the internet for solutions and got to know this must have something to do with user groups permissions, but couldn't find a satisfying solution. Is there anyone with an idea? Thank you in advance.

• How are minimum system requirements determined?

  - by Michael McGowan

  We've all seen countless examples of software that ships with "minimum system requirements" like the following: Windows XP/Vista/7 1GB RAM 200 MB Storage How are these generally determined? Obviously sometimes there are specific constraints (if the program takes 200 MB on disk then that is a hard requirement). Aside from those situations, many times for things like RAM or processor it turns out that more/faster is better with no hard constraint. How are these determined? Do developers just make up numbers that seem reasonable? Does QA go through some rigorous process testing various requirements until they find the lowest settings with acceptable performance? My instinct says it should be the latter but is often the former in practice.

• Reasons for Pair Programming

  - by Jeff Langemeier

  I've worked in a few shops where management has passed the idea of pair programming either to me or another manager/developer, and I can't get behind it at all. From a developer stand-point I can't find a reason why moving to this coding style would be beneficial, nor as a manager of a small team have I seen any benefit. I understand that it helps on basic syntax errors and can be helpful if you need to hash something out, but managers that are out of the programming loop seem to keep seeing it as a way of keeping their designers from going to Facebook or Reddit than as a design tool. As someone close to the development floor that apparently can't quite understand from a book tossed my way or a wiki page on the subject... from a high level management position, what are the benefits of Pair Programming when dealing with Scrum or Agile environments?

• Does schema.org improve SEO?

  - by marko

  http://schema.org This site provides a collection of schemas, i.e., html tags, that webmasters can use to markup their pages in ways recognized by major search providers. Search engines including Bing, Google, Yahoo! and Yandex rely on this markup to improve the display of search results, making it easier for people to find the right web pages. It sounds wonderful, but does the search spider ignore the extra attributes and elements? Is it just too clever and ignores it? May it also be that it lowers your visibility because of such alteration?

• Drawing an outline around an arbitrary group of hexagons

  - by Perky

  Is there an algorithm for drawing an outline around around an arbitrary group of hexagons? The polygon outline drawn may be concave. See the images below, the green line is what I am trying to achieve. The hexagons are stored as vertices and drawn as polygons. Edit: I've uploaded images that should explain more. I want to favour convex hulls because it's conveys an area of control more quickly. Each hexagon is stored in a multidimensional array so they all have x and y coordinates, I can easily find adjacent hexagons and the opposite vertex, i.e. adjacentHexagon = getAdjacentHexagon( someHexagon, NORTHWEST ) if there isn't a hexagon immediately adjacent it will continue to search in that direction until it finds one or hits the map edges.

• Calculating an orbit and approach velocties

  - by Mob

  I have drones in my game that need to approach and orbit a node and shoot at it. Problem is I want to stay away from a real physics simulation, meaning I don't want to give the node and drone a mass and the drone's thrusters' a force. I just want to find the best way to approach and then enter orbit. There was a pretty good answer about using bezier curves and doing it that way, but that is essentially a tween between two fixed points. The nodes are also moving as the drones enter orbit.

• C# Tip - Rendering HTML in a Gridview cell

  - by BobPalmer

  Just a quick tip for working with the gridview in ASP.Net.  If your data column contains HTML text, you've probably seen something like this in your gridview after pulling the data: <font color="red">First Item</font><br/><font color="green">Second Item</font><br/><font color="blue">Third Item</font> To have the relevant column render in HTML, just go to your gridview property pages, find the column you need rendered in HTML, and click 'convert this Field into a TemplateField'.  The result is that as a template field, HTML within your bound data value will be rendered properly.  So our example above would transform into: First Item Second Item Third Item I primarily use this technique for enabling HTML content in comment fields, and to insert line breaks when building the data for these fields. Hope this helps out! -Bob

• Interpolating between two networked states?

  - by Vaughan Hilts

  I have many entities on the client side that are simulated (their velocities are added to their positions on a per frame basis) and I let them dead reckon themselves. They send updates about where they were last seen and their velocity changes. This works great and other players see this work find. However, after a while these players begin to desync after some time. This is because of latency. I'd like to know how I can interpolate between states so they appear to be in the correct position. I know where the player was LAST seen and their current velocity but interpolating to the last seen state causes the player to actually move -backwards-. I could not use velocity at all for other clients and simply 'lerp' them towards the appropriate direction but I feel this would cause jaggy movement. What are the alternatives?

• What are safe keys to remap in vim?

  - by Weeble

  So far I've been trying to use Vim in as vanilla a configuration as possible, so as to save myself hassle when moving between machines. However, there are a few things I'd really like to bind keys, such as to shorten "_diwP which I use often to delete the word under the cursor and replace it with one from the clipboard. Are there any particular keys that are conventionally reserved for user-defined mappings? The point of this question is mostly that I would like to avoid hassle later on when I decide to install some plugin or take my configuration files to vim on another OS and find that my key mappings clash with something else.

• Ubuntu 12.10 TexLive 2012: Latex file would not compile

  - by Indian

  I wrote a long report with chapters using TexLiVE 2009. When I move to 12.10, the system had upgraded to Texlive 2012. However, I found that some fonts were not working, whereas they were a part of the distribution (Texlive). Therefore, I uninstalled the whole thing (TexLive) and then reinstalled. Compilation command pdflatex myreport.tex I now have the following error while compiling: This is pdfTeX, Version 3.1415926-2.4-1.40.13 (TeX Live 2012/Debian) \write18 enabled kpathsea: Running mktexfmt pdflatex.fmt I can't find the format file 'pdflatex.fmt'!

• Uninstall Calibri font, installed from Windows' font directory

  - by donkeydown

  I use e PC with both Ubuntu and Windows-7 OSs. I tried to install the Calibri font for Ubuntu in this way: I did open the calibri.ttf file in the Windows/Fonts directory using Font Viewer and clicked on the Install button. Now I need to disintall that font but I can't. Font Viewer shows me "Calibri Regular" font is installed but does not allow me to disintall it. Font Manager does not show Calibri in the font list. Character Map does not show Calibri in the font list. Ubuntu Software Center and Synaptic don't find anything like "calibri". There is no calibri file in those directories: usr/share/fonts usr/local/share/fonts ~/.fonts The font is visible to LibreOffice, Chrome, Firefox.

• How to install the translations for trac

  - by julien

  I have installed trac on my server running Ubuntu 12.04. The problem is that the users cannot change the language in their preferences. Instead, the following message is displayed: Translations are currently unavailable. Trac has been localized to more than a dozen of languages but in order to be able to use them, the Babel package needs to be present when installing Trac. See TracInstall for details. The installation has been done using the repositories of Ubuntu, but I could not find any package related to trac and babel, nor trac and anything related to internationalization. How can I install the translations for trac?

• Using Ubuntu without any knowledge of Linux

  - by Kiran Aaditya Jhonny

  Can I still install and use Ubuntu without any basic knowledge of a Linux operating system - do I need any background knowledge of Linux to use Ubuntu? If so, what will be the limits of my experience? Also, I heard from http://www.whylinuxisbetter.net/ that I don't need any drivers for hardware and peripherals. Can somebody shed some light on this statement? P.S. I don't know if these questions have been asked yet, I searched for these (maybe I didn't search hard enough), but I didn't find any.
