• How can I play AMR files in Firefox on Ubuntu?

  - by Dave M G

  I use Evernote to keep voice and text notes. Unfortunately, I've just discovered that I can't take full advantage of the cloud storage capabilities of Evernote, because support for Android's native sound file format, AMR, is deficient in Ubuntu. When I view my voice notes in Firefox in Ubuntu, I get a "missing plugin" error. The problem is discussed on the Evernote forums, but the solutions offered there are really lacking. They all involve saving and converting files, which seems like an unreasonable amount of fiddling. Surely an AMR file is just a sound file, and surely Ubuntu could (and should) have a way of playing it? There is some suggestion that Media Player can play AMR format, and I thought there was a Media Player plugin for Firefox. But I can not find any specifics. How can I get Ubuntu to play AMR file directly in Firefox in Ubuntu?

• Store HighRes photos in Database or as File?

  - by David

  I run a site which has a couple of million photos and gets over 1000 photos uploaded each day. Up to now, we haven't kept the original file that was uploaded to conserve on space. However, we are getting to a point that we are starting to see a need to have high-res original versions. I was wondering if its better to store these in the filesystem as an actual file or if its better to store them in a database (ie: mysql). The highres images would be rarely referenced but may be used when someone decides to download it or we decide to use it for rare processes like making a new set of thumbnails sizes/etc.

• ReportViewer configuration

  - by Suresh Behera

  Some of my team member was facing configuring report viewer.Most of the post are confusing or not able to understand properly. This is what we concluded and thought to put a quick note on it. No 1 Section : This is the report name No 2 Section : ReportServer make the default name on URL sometime even if you don’t see on browser you still need to try with “Reportserver” on url. In our case the DB/report team did not mentioned nothing about “ReprtServer” on URL but it was needed. No 3. “Adventure Works...(read more)

• What is the root of my application?

  - by railguage48

  Can someone help me understand what is the root of my application? I would like to use vim and create a one line procfile in the root of my application. Then I can test the procfile using a gem called foreman with the following command in my terminal: foreman start I have tried sudo vim /procfile and created the file and saved it in what I thought to be the root. Then I typed: foreman start and the response is that Procfile does not exist. Any help would be most appreciated.

• Deformation of Sphere using Transformations

  - by Mert Toka

  I have a graphic related question. I need to have a transformation matrix that I have no idea about what it is. The problem is to create right image from the right sphere. I created those images in Maya, but I need some matrices for the graphics course. Here is the image: Our professor told us to use some sine and cosine in our transformations, but I have no idea what he meant. I thought of intersecting a plane from the grid(that is xz plane) and sphere, and then scaling down the resulting circle. Would that work? I also checked this paper, however it looks like a bit advanced for me. Another thing is I guess that paper is not about the same type of information I was looking for. It would be great if you could help me.

• Do I have to completely reinstall Ubuntu now that it won't boot?

  - by Dave M G

  I just tried installing software called Teamviewer. It said there was some kind of error with unresolved dependancies. Then I realized I was trying to install the 32 bit version, but I needed to install the 64 bit version. So I tried that, and I got an error saying that Ubuntu needed to do a partial upgrade. I thought that was weird, so I just wanted to abandon installing anything and get out of this. I exited all programs and rebooted, and now I can't get back into Ubuntu. After the GRUB screen I get a black screen and no login options. If I boot into recovery, I get the following screen: I booted up a live CD of 12.04 to see if that could help, but it seems the only option is to completely reinstall Ubuntu. Can I repair this in any way, or is my only option to make a fresh install?

• XNA 4.0 SpriteFont not displaying all Characters

  - by Iain Brown

  Am looking for a little help and trying to use SpriteFont in my XNA 4.0 game but the problem is am displaying to string "This is a test" but all that's displayed on the screen is "This is st" so the "a te" are missing from the screen. The space is there for the characters but the letters are not. The code am using is: spriteBatch.Begin(SpriteSortMode.BackToFront, BlendState.AlphaBlend); spriteBatch.DrawString(font,"this is a test",new Vector2(692,372),Color.White); spriteBatch.Draw(texture,new Rectangle(0,0,100,100),Color.White); spriteBatch.End(); Any help with this would be great!

• How does apt-btrfs-snapshot work?

  - by Oli

  I read on the planet that apt-btrfs-snapshot would be available for Natty. The brief description of what it does sounds very nice: it will automatically create filesystem snapshot (of everything but /home) when apt installs/removes/upgrades. With the apt-btrfs-snapshot cli app its easy to list/remove/rollback the snapshots But before I convert my entire life to btrfs for the sole purpose of gaining a built-in backup system, can anybody tell me how btrfs's snapshots work. To my layman's brain, it sounds like this would eat a devastating amount of disk space if you're taking snapshots every time you install or upgrade something (I do this more than once a day). I assume the system is smarter than I'm allowing it but I really don't know. How do the snapshots work?

• PDF or ebook Java API documentation

  - by AmaDaden

  Since I have a long train ride to and from work I was wondering if there is a version of the Java API documentation floating around that I could put on my Kindle. It would be nice on the rare occasion I get something in my head that I want to think about some more. I know I can browse the web through the Kindle but coverage is spotty and slow. I know that the api docs are not really designed for a sequential reading format but I'm curious to see if anyone else has thought about this and given it a shot.

• GnuPG v1.4.10 cant read

  - by Nicky Bailuc

  I was thinking of "Getting Involved" with Ubuntu and decided to join the Bug Squad. After a few steps of joining, I got an email with a OpenPGP key licenced at Gnu version 1.4.10 and went on their website. They recommended me a couple of apps that can decode the code, but none of them worked, in fact each of them said that the code is corrupted. I thought that there's something wrong with that email, so I resent the request. As I got another email and tried the code with those programs, the programs said the same thing. How can I decode the code properly? Is there an online way of doing it? Any suggestions?

• Google Analytics showing more unique visitors than there are pages on an intranet site

  - by DDEX

  I take care of a company intranet and measure the traffic with GA. I am absolutely sure that there are no more than 5000 URLs in our company and it is impossible to check the intranet from outside the company network. Yet when I check the number of Unique Visitors (UV) in the last year GA says there were 36.500 of them. How is that possible? I thought UV should measure each URL only once in the given time period. Could anybody explain how this actually works? Can it be that the cookie trackers expire after some time and are counted more then once?

• Should a poll framework be closed sourced

  - by samquo

  I was having a chat with a coworker who is working on a polling app and framework. He was asking technical questions and I suggested he open source the application to get more quality opinions from developers who are interested in this problem and are willing to give it heavy though. He has a different point of view which I think is still valid so I want to open this question for discussion here. He says he believes something like a polling framework should not be open sourced because it will reduce its security and validity as people reveal loopholes through which they can cheat. Can't say I completely disagree. I see a somewhat valid point there, but I always believed that solutions by a group of people are almost always better than a solution thought by a single person asking a small number of coworkers, no matter how smart that person is. Again I'm willing to accept that maybe some types of applications are different. Does anyone have an argument in his favor? I'd really like to present your responses to him.

• Resizing my linux partition

  - by de1337ed

  So, I was getting rid of my openSUSE to install lubuntu. In the process, I didn't manage my hard drive partitions well enough and as a result, I lost my windows 7 partition. I got over the loss, and formatted my entire hard drive by install lubuntu over all the space. (I tried first installing windows 7, but I kept getting some weird errors during the partitioning process). I was wondering now if I could resize my lubuntu partition so I can install windows 7 again. Here is a gparted screenshot: Can anyone help me out? I have all my Linux disks and my windows disks. Thank you.

• Real-time chat in Ruby on Rails

  - by Skydreamer

  First, I'm sorry because I know this question has been asked many times but I'm still looking forward to finding the answer to my problem. I'd want to implement a Real-time chat for my Rails app but I can't really host the server which handles the sockets. I've tried Faye but it needs a server. I've also heard of pusher but it's limited to 20 users at a time on the chat and I can't really be sure they won't be more. I've thought of irc but I think I can't really embed it into a rails app, maybe it needs sockets... So here's my problem, can I implement a real-time chat without owning a server ? What can you advice me ? Thank you for your answers.

• The entire content of my Wordpress page has disappeared

  - by John Catterfeld

  I have a blog installed on my site using Wordpress. Last week I upgraded Wordpress from 2.6 to 3.0.4 (I had to do this manually). All went well, or so I thought, but I have just noticed that the content of an existing page has vanished. The page URL still works, but all content has disappeared - doctype, html tags, body tags, everything. Please note, this is specific to pages - posts are still displaying fine. I have since created a brand new page which does not display the content either. Things I have tried include Switching to a freshly installed theme Deactivating all plugins Setting the problem page to draft, and back again Deleting the .htaccess file I suspect it's a database problem and have contacted my hosting company who have said the only thing they can do is restore the DB from a backup, but that I should consider it a last resort. Does anyone have any further ideas what to try?

• Reading 'Index Status' graph in Google Webmaster tools

  - by sam

  I recently found a bunch of old files that had been ftp'ed to a live production server by mistake on a static (html / css / js) site. I manually deleted these files, but today when checking in Google Webmaster tools i found this graph below. The 'update' marker is from 3/9/14, what i can work out is what Google is trying to tell me, are they saying that : There was a ranking update like Penguin or Panda and they penalized my site and un-indexed a load of pages which they thought were junk.. OR Is this showing that I updated the site by deleting the files on the server on 3/9/14 OR Is this something else ?

• Rendering oily/polluted water?

  - by Fraser

  Any shader wizards out there have an idea of how to achieve an oily/polluted water effect, similar to this: Ideally, the water would not be uniformly oily, but instead the oil could be generated from some source (such as a polluting drain from a chemical plant) and then diffuse throughout the water body. My thought for this part would be to keep an "oil map" as a 2D texture that determines the density of oil at each point on the water surface. It would diffuse and move naturally with the water vel;ocity at that point (I have a wave-particle simulation for dynamic waves, and am already doing something similar for foam on the water surface). However, I'm not sure how physically correct that would be, since oil might not move at the same velocity as the water. And I have no idea how to make all those trippy colors :-). Thoughts?

• How do you handle measuring Code Coverage in JavaScript

  - by Dancrumb

  In order to measure Code Coverage for JavaScript unit tests, one needs to instrument the code, run the tests and then perform post-processing. My concern is that, as a result, you are unit testing code that will never be run in production. Since JavaScript isn't compiled, what you test should be precisely what you execute. So here's my question, how do you handle this? One thought I had was to run Unit Testing on the production code and use that for my pass fail. I would then create a shadow of my production code, with instrumentation and run my unit tests again; this would give me my code coverage stats. Has anyone come across a method that is a little more graceful than this?

• Good resources for JavaScript 2D game programming?

  - by DJCouchyCouch

  As an exercise, I've decided to look into JavaScript for game programming. While it's far from being the best language for that, I do like the idea that it's cross-platform and it's always available as a web page. So I thought I'd see what I could do with it. Specifically, I'd like to make a 2D tile-based game of some kind. Where can I find resources to do that? I'm sure this question's come up before, but I can't find any reference to it.

• Is writing software in the absence of requirements a skill to possess or a situation I should avoid?

  - by Brian Reindel

  I find that some software developers are very adept at this, and often times are praised for their ability to deliver a working concept with abstract requirements. Frankly, this drives me crazy, and I don't like "making it up" as I go. I used to think this was problematic, but I've started to sense a shift, and I'm wondering if I need to adjust my thought (and programming) process when given very little direction. Should I begin to acquire this ability as a skill, or stick to the idea that requirement's gathering and business rules are the first priority?
