I really like being able to develop in .NET on linux, and I think that the mono team has come a long way in its efforts to make mono-based applications production-viable.  Sadly, I'm guessing that the majority of mono developers use mac, opensuse, or windows because those are the only platforms that dependably have pre-built binaries and installers.  Since I use Mint (a variant of Ubuntu), I'd really like a simple method for installing a current version of MonoDevelop. Recently, I needed to install Mint on my new laptop and so I payed close attention to how I installed MonoDevelop and turned it into a script -- which you can now use!  I've tested it on a fresh Mint 12, but it should also work on Ubuntu Oneiric. The script: Installs the git client and the dependencies necessary to build MonoDevelop from source. Downloads the source code for MonoDevelop from github. Configures the build script to install the stable profile into /usr/local (/usr/local/monodevel...

CouchDB has a really great idea behind it.  Whether or not CouchDB delivers on it, I've been wanting to discover for a while.  Only way to do that is kick the tires, so I started the process of figuring out how to install it. First disappointment is discovering a general lack of documentation.  But my first appreciation is how simple it is once you figure out what needs to be done. CouchDB runs on erlang, so you need to install erlang from the EPEL repository.  In order to use that repository on CentOS 6, run the following command: sudo rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-5.noarch.rpm Now you can install erlang: sudo yum install erlang That will bring with it a number of dependencies, such as wxWidgets.  With erlang now available, it's time to download the CouchDB source code from here . As of this writing, the latest release is 1.2.0, although 1.3 is in alpha in master.  I'm electing to use the stable releas...

Today, I was attempting to digitally sign a byte array with my private key so that I could produce an event on the event bus and a consumer could ensure that the message came from me and was not modified while in transit. public byte[] SignData(byte[] data) {   X509Store certStore = new X509Store(StoreName.My, StoreLocation.CurrentUser);   certStore.Open(OpenFlags.ReadOnly);   // the DN I get is CN=name,CN=Users,DC=example,DC=com   // but the DN on the cert has spaces after each comma   string spacedDN = UserPrincipal.Current.DistinguishedName.Replace(",", ", ");   X509Certificate2 cert = certStore.Certificates     .Find(       X509FindType.FindBySubjectDistinguishedName,       spacedDN,       true)     .OfType<X509Certificate2>()     .FirstOrDefault();   if (null == cert) { ...
