• Graphically intensive silverlight design

  - by Rick Hodder

  I'm designing a silverlight application for showing sheet music from a midi file. I want to create a horizontally scrolling musical staff. At my job I maintain a winforms application that is a scrolling Gantt chart of airplane schedules, and it basically has a rows collection, and it maps the left-most pixel and right-most pixels of the control to datetimes. Then the paint method loops through what it determines will be the visible rows, and draws a screen that shows the schedule information between the two dates. Would I be correct in assuming that I would need to something similar in silverlight for my sheetmusic, or would it be better to just create a horizontal scrollviewer containing a canvas that I have drawn programmaticially on. Am I headed in the right direction? I havent seen any articles on designing such a custom control: can you point me at any?

• Gnome indicator applet not showing same items on two computers

  - by EmmyS

  I have one computer running Lucid and another one that I recently upgraded to Maverick. Up until today, I was using AWN with Maverick, including their custom indicator applets. I've decided to switch back to the default gnome panels with dockbarx, but when I add the indicator applet to my panel, it's not displaying the same items as the applet on my Lucid machine. In particular, the network and Dropbox icons are not displaying. When I look at the About entry for the apps, Lucid shows version 0.3.7, whereas Maverick shows 0.4.6. Did they really remove the network information from the applet in Maverick, or do I need to do something to enable it? My network is very definitely connected, as I still have AWN running and can see the icon there. (A second question, although not particularly important: the applet doesn't inherit the transparency of the panel it's living on - any way to change that?)

• Webshop for digital goods with voucher / gift card system [duplicate]

  - by Kelzama

  This question already has an answer here: Which Ecommerce Script Should I Use? 1 answer I'm searching for a webshop which provides the following: The shop offers digital goods (like mp3) User can buy a voucher / gift card @Reseller (Or there is a code provided in the CD) User can enter his code @ webshop and gets the download (unregistered) User can enter his code @ webshop and download is added to his/her library (registered) optional: Resellers can buy codes from the Webshop I already tried prestashop as it looks quite nice. But it needs a lot of custom programming (and has a very strange voucher-system). Customer has to add the File into the basket and add the voucher at checkout. I want to skip that ;) Is there a Webshop (Or CMS + Plugin) which provides the things I need? (it could also be a CMS with a Storage/Folder Plugin (like joomla + K2) and a possibility to activate downloads via unique Codes.) Any ideas are highly appreciated :) Thanks in advance.

• Pointing a subdomain to Github Pages

  - by ratage

  I set up an Octopress blog on Github Pages at myusername.github.com. I now want blog.myusername.me (which currently has a Wordpress blog set up) to point to this Octopress blog. So I followed the instructions here on setting up a custom domain: I ran echo 'blog.myusername.me' >> source/CNAME in my Octopress repository, and then ran rake generate and rake deploy to deploy it to Github. I went to Namecheap, and added a new CNAME under my myusername.me domain: "blog - myusername.github.com - CNAME". Waited a couple hours. However, now when I go to myusername.github.com, it redirects me to blog.myusername.me (which is my old Wordpress blog), which seems like the inverse of what I want. (Going to blog.myusername.me directly still shows my Wordpress blog.) I checked http://www.whatsmydns.net/#CNAME/blog.myusername.me and it seems like my DNS has propagated (myusername.github.com shows up in the right-hand side). Any ideas what I'm doing wrong?

• How to enable rgb colored output in terminal?

  - by t.pimentel

  I'm trying to print a colored string to a gnome-terminal using ANSI escape codes, but, although it works for the custom colors, or even the 256 extra color, it doesn't work with RGB codes. So, simplifying: cout << "\033[33m" << '.' << "\033[0m"; # prints with color cout << "\033[38;5;135m" << '.' << "\033[0m"; # prints with color cout << "\033[38;2;0;135;0m" << '.' << "\033[0m"; # doesn't work, prints with default color How can I output something with an RGB color code in the gnome-terminal? I'm following this link for outputs: Wikipedia ANSI escape code.

• How agile methodologies can be applied in a typical " services " company?

  - by AlfaTeK

  My company is a custom software services company for external clientes, which means our typical project is one in which the contract already states the full budget of the project. Our typical project starts by defining requirements (improving the proposal high-level requirements), then we code the project, test it and ship it. We have an acceptance phase were the client tests the software and in that phase we can usually implement small changes asked by the client, or we charge extra for change requests. In some projects we have intermediate releases so the clients can check the progress of the project and give feedback on it. In summary: something like waterfall... I've followed the "agile" movement for a bit now and I always see it being a good match for a "product" company, or a company building software for an internal client. But are there good stories / advantages on using agile methods in my kind of company/projects? What are your experiences, what do you think about this?

• Moving a body in a specific direction using XNA with Farseer Physics

  - by Code Assasssin

  I have a custom polygon attached to a body, which looks like this: What I am trying to accomplish is getting the body to move according to wherever the tip of the body is. So far this is what I've tried: if (ks.IsKeyDown(Keys.Up)) { body.ApplyForce(new Vector2(0, -20),body.GetLocalPoint(new Vector2(0,0))); } if (ks.IsKeyDown(Keys.Left)) { body.ApplyTorque(-500); } if (ks.IsKeyDown(Keys.Right)) { body.ApplyTorque(500); } The body rotates fine - but when I try making the body accelerate according to the tip of the body - assuming I have specified the tip correctly(I am pretty sure I haven't), it just spins around, as if I have applied Torque to it. Can anyone point me in the right direction of how to fix this problem?

• How does one block unsupported web browsers?

  - by Sn3akyP3t3

  Web browsers with an end of life no longer receive security updates which not only makes them vulnerable to the end user, but I imagine its not safe for the server's which receive visits by them either. Is it practical to block or enforce and notify the end user that their browser is unsafe and unsupported? If so, how would one achieve that? I don't know of any official or crowd-sourced listing with that information to parse and keep up to date. I'm aware that the practice can be custom built with User Agent parsing and feature detection for HTML5 enabled browsers.

• 12.04 Ambiance dark side bar issue when clicking folder on desktop

  - by Lou Crittenden

  Concerning an updated custom ambiance theme: why is there no dark side bar when I click on a folder, like the home folder icon on the desktop, but the theme works as planned when I type nautilus in the terminal to open the home folder or when opening a folder up as root? Permissions issue perhaps? Note: I am using Cinnamon instead of Unity and I noticed it uses the Nemo file manager instead of Nautilus and I suspected that it was causing me the grief. I uninstalled it and now am using Nautilus only as the file manager. I found this out when I typed: sudo killall nemo and the problem went away. I'll see how this goes (and hopefully cinnamon doesn't care about it...) Has anyone else had any issues with this?

• BlissControl Is a Settings Management Dashboard for Popular Social Networks

  - by Jason Fitzpatrick

  BlissControl is a simple web app that organizes the different settings menus of over a dozen social networks and services into a streamlined dashboard to help you change your profile pic, privacy settings, and more. Much like previously reviewed NotificationControl and MyPermissions (which help you check and set email notifications and app permissions, respectively), BlissControl also takes the very convoluted menus of web-apps and social media sites and makes them super easy to navigate. You can easily click right through the page you need on Facebook, Flickr, Twitter, and more–you’ll no longer need to visit each service and click through a maze of menus to get to the right place to change your password or swap your profile pic. BlissControl is simply a dashboard that directs you to the appropriate page within the service you already use–you never share your login credentials with BlissControl.

• why is emacs allowing multiple instances?

  - by Chad

  Around the time I fresh installed Ubuntu 12.04, I noticed that I can start multiple instances of Emacs. I find this annoying because I will think that a buffer should be open, but I'm in the wrong Emacs window. I may have changed something in .emacs, but I really don't think I did. I also reverted all of my customizations that are stored in ~/.emacs.d/custom.el. Emacs previously would give some error about another emacs server being open when I would attempt to start an additional instance of it, but it no longer does this. Any ideas on how to restore this behavior?

• Why can I only put some items in the launcher?

  - by HaskellElephant

  Whenever I search for an item using dash it knows the default way of opening it. However if I drag a file into the launcher it can't be added, even if it is executable. For example if you would like minecraft to show up you will have to add a custom launcher, or if you use dash to find a pdf file, you can double click it and it opens evince however you cannot drag it into the launcher. The animation surrounding this behavior suggests that this was done by design. Why is this useful or necessary? Is it a bug?
