I tried to open Gnome-RDP in Monodevelop, and this is the error that I get:
Could not obtain a C# compiler. C# compiler not found for Mono / .NET 3.5.
The fix is to simply change the compiler target on the project’s properties. Right click on the project and choose “Options”.
Then, change the runtime version.
Changing it to 4.0 fixes the project.

To exist in a world dominated by Microsoft products, you have to be able to coexist with others using those products. That includes connecting to shares via Samba, using remote desktop, and opening Office documents. When it comes to office documents, Libre Office does the job for the most part. I have had pretty good success using Libre Office even with Microsoft Office files. The problem comes when you bounce a document back and forth between Libre Office and Microsoft Office.
If you are working in a team with other Microsoft Office users, you are going to have to break down and install Microsoft Office. Below you will see the screenshots of how I installed Office. At the end, you can find other methods.
I have seen a flurry of activity on the XDA Forums for development of Ice Cream Sandwich/Android 4.0. So, I wanted to create my own little list of ROM threads.
Here’s a list of what I have found so far:
If you want to watch the fun with me, check out this list of ROMS:
Note: I found an article on Engadget that suggests that we need to wait until January for ICS on Cyanogen.
On a side note, Engadget pointed out that my old phone (the G1) now has ICS, too! ICS is getting around!
I just had an issue with VMWare where the kernel modules would not compile. Here’s the details and the solution:
I get the “Unable to Start Services” and the Virtual Network Device has a warning symbol next to it:
Digging around in the log, this is the closest thing that I could find to an error:

I can’t start the services manually:
$ sudo service vmware start
Starting vmware (via systemctl): Job failed. See system logs and 'systemctl status' for details.
[FAILED]
If you start vmware from the command line, you’ll see this error buried in the output:
/tmp/vmware-root/modules/vmnet-only/compat_netdevice.h:220:1: error: conflicting types for ‘netif_queue_stopped’
Here’s just a little more information about my system (Fedora 15):
$ uname -r 2.6.41.1-1.fc15.x86_64
Here’s my VMWare version:
$ vmplayer --version VMware Player 4.0.1 build-528992
I found a post that suggested several fixes. First, I installed the hal package:
sudo yum install hal
I don’t know if that contributed toward the solution or not.
I had to downgrade to an earlier version of VMWare. To do so, I had to uninstall my current version with:
sudo vmware-installer -u vmware-player
After downloading the previous version, I installed it with:
sudo bash VMware-Player-4.0.0-471780.x86_64.txt
Next, I found a post with a patch.
cd /usr/lib/vmware/modules/source sudo cp vmnet.tar backup_vmnet.tar sudo wget -O vmnet.tar "http://forums.fedoraforum.org/attachment.php?attachmentid=22156&d=1321890579"
Then, I compiled the modules with:
sudo vmware-modconfig --console --install-all
I still got messages about the service not being able to start, but it still ran and booted my virtual machine.
While the above instructions solved my problem, let me walk you through some of the other things I tried. That might give you some more ideas if what worked for me didn’t work for you.
I found a post that suggested uninstalling and reinstalling. So, here is the how I did it:
First, I had to determine the exact name of what was installed:
$ vmware-installer -l Product Name Product Version ==================== ==================== vmware-player 4.0.1.528992
Then, here is the command:
sudo vmware-installer -u vmware-player
And after I downloaded the latest version, I had a “txt” file. It is really a script, so I ran it like this:
sudo bash VMware-Player-4.0.1-528992.x86_64.txt
Here’s something that I tried in case it might help you. It didn’t help me any.
I downloaded a patch from Weltall’s blog: vmware8linux31fix.tar.gz. Then, I extracted and ran the patch:
[skp@pecan vmwarefix]$ tar -xzvf vmware8linux31fix.tar.gz vmware3.1.0.patch patch-modules_3.1.0.sh [skp@pecan vmwarefix]$ ls patch-modules_3.1.0.sh vmware3.1.0.patch vmware8linux31fix.tar.gz [skp@pecan vmwarefix]$ sudo ./patch-modules_3.1.0.sh Sorry, this script is only for VMWare WorkStation 8.0.0 or VMWare Player 4.0.0. Exiting
The error message indicates it is looking for a particular version, so I just adjusted the script a little bit. At the top of the script, I changed the version number:
Next, I just got another error message:
[skp@pecan vmwarefix]$ sudo ./patch-modules_3.1.0.sh /usr/lib/vmware/modules/source/.patched found. You have already patched your sources. Exiting
I found a post that suggested that someone was missing a bunch of packages. That gave me an idea to try to find what package included version.h. Then, this post suggested that they were in the Linux headers package. I did have the headers installed:
$ rpm -q kernel-headers-`uname -r` kernel-headers-2.6.41.1-1.fc15.x86_64
I tried to install this:
sudo yum install buildsys-build-rpmfusion-kerneldevpkgs-current
Again, this didn’t work. The packages installed, but vmware still wouldn’t build.
Thanks to TyTung, I now have Ice Cream Sandwich / Android 4.0 running on my phone!
You can view his work here:
I recently had an issue with Tamper Monkey, jQuery, subdomains. You can view the issue here:
tampermonkey.net: subdomain + jQuery issue
Basically, my page would load jQuery plugins when I hit the page directly from my site. But, if I hit the page via a subdomain off the website, the plugin would not load. Any javascript that used that plugin would err as if the plugin did not exist. When I disabled TamperMonkey and reloaded the page, everything would work through the subdomain again.
You can try it with this tech test. This is without the subdomain:
http://example.digitaleagle.net/subdomain.php
This is through the subdomain:
http://example.digitaleagle.net/subdomain.php
You should get alert dialogs when the page loads and when you click the button.
The fix is to use the Beta version of Tamper Monkey. This latest version fixes the bug. You can download it from here.
Also, just FYI, here is my original thread asking for help:
At one point, I thought WebEx was working natively in 64-bit Linux. Either I am mistaken or it no longer works on 64-bit. So, I decided to dust off my old 32-bit hack where you install 32-bit versions of Java and Firefox to make it all work.
Earlier, I had thought I would use my regular 64-bit installation, and I had posted my hooking Java up to Firefox for WebEx. I was rightly corrected on troshlyak’s blog. The 64-bit will work, but you can’t share your desktop or view another’s desktop. So, I am back to the old way. So, here’s what I did…
I downloaded the two programs:
Environment Script:
I created this script in ~/bin/webex/env.sh:
#!/bin/sh export WEBEX_HOME=~/bin/webex export JDK_HOME=$WEBEX_HOME/jdk1.7.0_01 export JAVA_HOME=$JDK_HOME/jre export FIREFOX_HOME=$WEBEX_HOME/firefox export MOZ_PLUGIN_PATH=$FIREFOX_HOME/plugins export PATH=$FIREFOX_HOME:$JAVA_HOME/bin/:$JDK_HOME/bin/:$PATH
To make sure you have it right, you can check it like this:
[skp@pecan bin]$ . ~/bin/webex/env.sh [skp@pecan bin]$ which java ~/bin/webex/jdk1.7.0_01/jre/bin/java [skp@pecan bin]$ java -version java version "1.7.0_01" Java(TM) SE Runtime Environment (build 1.7.0_01-b08) Java HotSpot(TM) Server VM (build 21.1-b02, mixed mode)
Now, you can link in the Java plugin like this:
mkdir $MOZ_PLUGIN_PATH ln -s $JAVA_HOME/lib/i386/libnpjp2.so $MOZ_PLUGIN_PATH/libnpjp2.so
Now, fire up firefox. Note you may be asked to create the WebEx profile. Make sure you create a profile with the same name you use on the command line so it won’t ask you again.
firefox --no-remote -P WebEx http://java.com/en/download/testjava.jsp
This should give you a successful Java applet working on the test page. You also should see the architecture as i386.
Finally, I created a ~/bin/webex.sh script to launch webex easily for me.
#!/bin/bash cd ~/bin/webex . ./env.sh firefox --no-remote -P WebEx
And you should be good to go.
I am always open to more lists of WordPress Plugins:
Lunarpages Blog: Ten WordPress Plugins Worth Considering
The one I picked up from this list was WP Super Cache. My blog definitely needs a speed boost.
The next one I probably need to come back to is the Mobile Press. The only problem is that the link was broken. I’ll have to come back and research that later.
So, let me add a few of my own:
Ad Injection: Previously, I had tried to implement the ads manually into my theme. I found that they were slowing the site down. This plugin makes implementing ads correctly easier, and it gives you more options as well.
Edit Flow: While it is just me blogging, I still use this plugin to try to organize my posts. I have created a “Stub” status that I use when I find a topic that I want to write about. Then, I created a “Needs Research” status to indicate that I still have work to do before finishing the article. I also created a “Pending Review” status to remind myself to review the article one more time before publishing.
Jetpack: If you don’t already have this installed, WordPress should start to bug you about it. For me, it just means better looking stats. I need to delve into setting up some of the other features in it.
Yet Another Related Post Plugin: I need to spend more time on theming the related section, but this plugin seems to make the “related” section at the bottom pretty easy.
Since this last upgrade to WordPress 3.2.1, I have been having trouble using the link button in the Visual Editor. The link button doesn’t do anything, and looking in the Javascript Console, I see an error. I’ve noticed that it works in Firefox but not Chrome. Also, it works fine in the HTML view but not the Visual view.
The weird part is that I installed a fresh installation of WordPress using Lunar Page’s Softaculous system. The new installation had no problems.
I found a pretty nice forum post that has some things to try. Unfortunately, none of them really worked. I have disabled all of the plugins, and that didn’t seem to make a difference. I also installed all of the plugins into my new instance, and that didn’t break that one. I copied all the wp-includes from the new instance to the old one, and that didn’t fix it either.
I did find a work around: TinyMCE Advanced. Under settings, I enabled the “Advanced Links”. That replaces the dialog and works around the javascript error.
I would love to fix it for good through. Please comment if you have any other ideas.
I had trouble printing from my laptop to the printer on my Ubuntu server. It took me a bit to figure it out, but I finally figured out that it was the Firewall.
When I looked in the Printer properties, I saw the message:
Stopped – /usr/lib/cups/backend/ipp failed
To troubleshoot, I ran “system-config-printer” on my server (I ran it through ssh so I didn’t have to walk into the other room). Then, I unchecked “enabled” on the printer so I didn’t waste any paper.
Then, I tried to print from gedit. It wouldn’t work at first.
Next, I opened “Firewall Configuration”. You can launch it from the command line with “system-config-firewall”. On the toolbar, click “Disable” and “Apply”. Then, I tried to print again. For me, I was able to print with no problem.
If that is the same for you, try checking these two options:
For me, these two options were already checked. I had removed and re-added the printer, and somewhere along the way it asked if I wanted to open the printing ports in the firewall. That’s what made me check the firewall in the first place. Well, I found a post that suggested that it configures the firewall but doesn’t apply the changes. Sure enough, when I re-enabled the firewall and hit apply, I was able to print from gedit!
