• grub2 loopback booting ubuntu server iso

  - by Thermionix

  I've got usb-keys setup to multi-boot different linux images using grub2 loopback. The standard ubuntu release isos boot fine, however when attempting to use the server iso it will fail to install saying 'unable to detect cd-media for installation'. the grub.cfg entry; menuentry "ubuntu-12.04-server-amd64" { set isofile="/boot/ubuntu-12.04-server-amd64.iso" loopback loop $isofile linux (loop)/install/vmlinuz file=$isofile/preseed/ubuntu-server.seed ro noprompt noeject -- initrd (loop)/install/initrd.gz } I've attempted to add the following parameters as the fromiso works for debian images on the key iso-scan/filename=/boot/ubuntu-12.04-server-amd64.iso iso-scan/filename=/dev/disk/by-uuid/2859-44B7/boot/ubuntu-12.04-server-amd64.iso fromiso=/dev/disk/by-uuid/2859-44B7/boot/ubuntu-12.04-server-amd64.iso

• Let&rsquo;s try this again&hellip;

  - by svanvliet

  So it’s been a really long time since I consistently blogged on my previous ASP.NET blog (and, let’s be honest, it wasn’t that consistent to begin with!)  With the mainstream use of microblogging sites like Facebook and Twitter, I’ve been able to post more frequent updates (http://www.facebook.com/scott.vanvliet & http://twitter.com/scottvanvliet) but haven’t really authored any good content lately. Well, I decided it’s time for me to try again! I’ve relocated my blog from the ASP.NET weblogs site to my new home here at http://geekswithblogs.net (thanks @jjulian and @jalexander!)  I hope to be posting musings on here about Silverlight, motion graphics, digital media, digital supply chain, and even personal/fun stuff. Stay tuned!

• Mounting Samsung Galaxy S2 via USB on Ubuntu 13.04

  - by argvar

  Connecting my Samsung Galaxy S2 to Windows 7 worked seamlessly. Now that I'm on Ubuntu 13.04 I'd like to access my phone's drive via the USB cable, but that's not working. When I do plug it in I get a error message in Ubuntu: Unable to mount SAMSUNG_Android Unable to open MTP device '[usb:002,008]' Then when I unplug it I see a error message on the phone: Attention Unable to find software on your PC that can recognize your device. Service pack 3, Windows Media Player, version 10 or higher, for Windows XP or Android FIle Transfer for Mac OS must be installed. You can download and install PC Kies from http://www.samsung.com/kies in order to sync data with your device, back up data, and upgrade your device (Windows and Mac OS are supported) What can I do here to fix this? I don't want to use any special software with the phone, just access the phone's drive.

• Displaying Tweets in an ASP.NET UserControl with TweetSharp

  As I mentioned in my previous blog post, I'll be having a little fun over the next few weeks talking about all of the Social Media APIs I've been experimenting with. I thought I would start out today by talking about one of the most popular services, Twitter. Twitter is essentially a microblogging service that allows its users to post messages of up to 140 characters long known as Tweets. Users can subscribe to each other and see tweets from all of their subscriptions in their main feed listings. Due to this ease of providing and receiving updates to and from the masses, Twitter has been adopted by anything from bloggers to celebrities to large corporations. If you have a blog or just a website in general, having a Twitter account alongside it could potentially be a useful way to attract new visitors. Displaying your tweets on your website and ...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. Take a look: here.

• IVR-style dialog system / workflow / menu

  - by unbeli

  I need to build a dialog system similar to IVR used in call centers. My system is not phone-based, but the dialog is similar. Something like System: "Main menu: Enter [1] for menu1, [2] for menu2" User: [1] System: "menu1: enter [1] for apples, [2] for oranges, [3] for main menu" User: [7] System: "What??" System: "menu1: enter [1] for apples, [2] for oranges, [3] for main menu" User: [2] ... and so on I want to have a nice declarative description of all the possible options and a nice way to run through that tree, guided by user input. Already considered: ANTLR-generated lexer/parser (seems to be an overkill), SCXML-based state machine (seems like only transitions can be declared, the rest needs to be coded)

• Only MKV format available in HandBrake

  - by Steve Ellis

  I am running Ubuntu 14.04 LTS 32 bit. I have installed HandBrake rev5474 (i686), which I believe is the latest, and the Ubuntu Restricted Extras. I am able to play DVDs via VLC but when it comes to ripping them, so that I can back them up to my Twonky media server, I have issues. I launch HandBrake and find that the only format available for me to select is MKV. When I used to run Handbrake on this machine while I was running Ubuntu 13.10 and lower I had no issues and **lots of formats (including MP4 which is what I'm really after) but since reformating and installing 14.04 I've had this issue. Any help would be much appreciated.

• Facing problem with "gtk.RESPONSE_OK" in the simple-player quickly tutorial

  - by sumit_gt

  I am fairly new to both quickly and Python. I am facing several problems while learning to use quickly from the following tutorial on the Ubuntu developers site: http://developer.ubuntu.com/resources/app-developer-cookbook/multimedia/creating-a-simple-media-player/ The following error I'm unable to understand: Traceback (most recent call last): File "/home/sumit/Sumit/simple-player/simple_player/SimplePlayerWindow.py", line 36, in on_openbutton_clicked if response==gtk.RESPONSE_OK: NameError: global name 'gtk' is not defined I realize that I am supposed to import something, so I tried to add import gtk which it didn't work and it gave the following error: from gtk import _gtk /usr/lib/python2.7/dist-packages/gtk-2.0/gtk/__init__.py:40: Warning: g_type_get_qdata: assertion `node != NULL' failed from gtk import _gtk I have followed every step of the tutorials so far. But there is no mention of any other imports other that "prompts" and "os". Please help. Contribution of Agmenor, facing the same problem: I also tried to replace the text if response == gtk.RESPONSE_OK: by if response == Gtk.RESPONSE_OK: (notice the capital G). This gives another error: AttributeError: 'gi.repository.Gtk' object has no attribute 'RESPONSE_OK'

• HD Video on Pandaboard ES

  - by Lord Loh.

  I am running Ubuntu 11.10 on my Pandaboard ES. I attempted to playback a 720p / 1080p video. In both cases, the videos were highly jittery and the audio seemed to be plagued with something that seemed to be white noise (sounds like white noise, but it definitely is not white noise). I was using VLC media player for playback and was running XFCE4 as the desktop ewnvironment. The system monitor graph indicates both the CPU cores running ~100%. Lower resolution videos seemed to play without problems. How do I play 1080 / 720 HD videos on pandaboard? Thanks in advance.

• How to increase ad revenue

  - by Brian515

  I have an Android game in which I've included ads from Millennial Media and Admob. Between these two networks, my fill rate is consistently above 95%. Right now, I'm getting over 45,000 requests for ads per day, and I'm starting to see exponential growth. But, my eCpm for both Millennial and Admob is ridiculously low. Millennial's is $.12 and Admob's is $.01. I've been reading some other posts and it seems like people are getting between $1 and $4 per 1,000 views. How can increase mine? Thank you!

• Is there a HIPAA certification that would be helpful to programmers?

  - by Aequitarum Custos

  I work at a Medical Billing company that's software handles many facets of the centers practice, including patients, treatments, etc. To be frank, the only thing I know about HIPAA is security is paramount. I was wondering if there were any training courses with an earned certification proving knowledge/experience that I could use to increase my worth to the company, and give them a selling point (we have HIPAA certified employees). I did a Google search and found this site, but it does not appear legitimate, and I'm trying to avoid any of those fake certification/degree sites. Does anyone know of any recognized and legitimate (preferably government sponsored) HIPAA certifications useful to programmers? If state is a factor, I live in Oklahoma.

• bash profile works for user but not sudo

  - by user564448

  I've modified my .profile to include a folder if a flash drive is plugged in. When running the command as the user it works fine but tells me the scrip must be run by sudo (this is what i want). However, when i try to run it with sudo i get "command not found" I have a symlink (flash) in my /var/www folder pointing to my /media/flash drive. (nevermind this setup since is just for dev) this is my user's .profile : # set PATH so it includes flash scripts if [ -d "/var/www/flash/scripts" ] ; then PATH="/var/www/flash/scripts:$PATH" fi when trying to run as sudo i get: sudo: script: command not found any ideas?

• MP4 files show up but won't stream to xbox 360

  - by Greg

  I set up a basic media server to stream to my 360 using uShare. Here are the instructions I used: http://linuxexpresso.wordpress.com/2011/01/02/howto-ubuntu-upnp-server-to-xbox-360/. I can stream avi files fine but I cannot stream mp4s. When I go to videos on the xbox, I can see all of the videos and folders but when I click play for an mp4 nothing happens. On my ubuntu desktop I can click on the mp4 file and it plays fine. And if I take that file, stick it on a thumb drive and plug it directly into the xbox the mp4 will play off the thumb drive. I'm lost for why it won't work through ushare. Any ideas?

• Share on Facebook does not show thumbnail images

  - by matt_tm

  I have a PHP application which has a "Share on Facebook" button that, On the development server shows the thumbnail images correctly and allows the user to select between them On the live server, it does NOT show the thumbnail images at all. The relevant portion of the .htaccess file is: # Set up caching on media files for 2 days <FilesMatch "\.(gif|jpg|jpeg|png|flv)$"> ExpiresDefault A172800 Header append Cache-Control "public" </FilesMatch> I'm using the exact same set of php files and .htaccess, but the server configuration is different. What could be causing this? Note that the text appears fine. Edit1 We are also doing some URL rewriting related to images in the .htaccess (on both servers): ... RewriteRule ^.*/content/image/(.*)$ content/image/$1 [L] ... RewriteRule ^.*/images/(.*)$ images/$1 [L] ... Would that be somehow making a difference? Images appear fine all throughout the site. (I posted this question earlier as http://stackoverflow.com/questions/4142597/share-on-facebook-does-not-show-thumbnail-images) )

• Django ORM and PostgreSQL connection limits

  - by bennylope

  I'm running a Django project on Postgresql 8.1.21 (using Django 1.1.1, Python2.5, psycopg2, Apache2 with mod_wsgi 3.2). We've recently encountered this lovely error: OperationalError: FATAL: connection limit exceeded for non-superusers I'm not the first person to run up against this. There's a lot of discussion about this error, specifically with psycopg, but much of it centers on older versions of Django and/or offer solutions involving edits to code in Django itself. I've yet to find a succinct explanation of how to solve the problem of the Django ORM (or psycopg, whichever is really responsible, in this case) leaving open Postgre connections. Will simply adding connection.close() at the end of every view solve this problem? Better yet, has anyone conclusively solved this problem and kicked this error's ass?

• ubuntu cobbler server - importing distros

  - by Stu2000

  I setup and fully configured ubuntu-12.04-server machine with cobbler/dhcp running in about 10 minutes (compared to taking over an hour on centos 5.8). I discovered the cobbler import which appears to be useful. Does this remove the need to use a cobbler distro add? whenever I run a cobbler report after a successful import of ubuntu desktop iso: sudo cobbler import --name=Ubuntu --path=/mnt --breed=debian task started: 2012-12-13_163245_import task started (id=Media import, time=Thu Dec 13 16:32:45 2012) Found a debian/ubuntu compatible signature: pool adding distros avoiding symlink loop avoiding symlink loop avoiding symlink loop associating repos associating kickstarts *** TASK COMPLETE *** I just get the following (nothing): distros: ========== profiles: ========== systems: ========== repos: ========== images: ========== mgmtclasses: ========== packages: ========== files: ========== I was rather hoping that I wouldn't have to do the traditional copying of all files in /mnt to a new /distro directory and then perform a cobbler distro add --initrd=/path/to/inird --kernel=/path/to/kernel Maybe I am mistaken about what the import actually does for me. If someone could elaborate on what the import is actually for please do.

• Is switch-case over enumeration bad practice?

  - by Puckl

  I have an enumeration with the commands Play, Stop and Pause for a media player. In two classes I do a switch-case over the received commands. The player runs in a different thread and I deliver the commands in a command queue to the thread. If I generate class diagrams the enumeration has dependencies all over the place. Is there a nicer way to deal with the commands? If I would change/extend the enumeration, I would have to change several classes. (Its not super important to keep the player extensible, but I try to write nice software.)
