Wireless Woes

2008/03/31

One thing that I wanted to get to work was my wireless network on my Dell D830 laptop with Ubuntu. The first hurdle was that I had turned off the wireless network switch. Took me a while to figure that out 😦

Unfortunately afterwards it still didn’t work. A lspci revealed that I have a Broadcom BCM4327 wireless card. A search on Google showed that Ubuntu Hardy Beta still has a problem with the order in which modules get loaded.

When I do the following commands I can get it to work:

sudo rmmod ssb

sudo rmmod ndiswrapper

sudo modprobe ndiswrapper

sudo modprobe ssb

I think that for now I’ll do these steps manually (since I need wireless LAN only occasionally) and hope they will fix this problem for the final release.

Update: it seems that this got fixed. I don’t have to do these steps manually to get my WLAN to work.

Using C# 3.0 Features with .NET 2.0

With Visual Studio 2008 Microsoft also updated the C# language. C# 3.0 brings several new and useful features that are described in a MSDN article.

Visual Studio 2008 will always compile with the new C# 3.0 compiler even when you select .NET Framework 2.0 as target framework in your project.

This raises an interesting question: is it possible to use the new features of C# 3.0 even when you use .NET Framework 2.0? And which new features can you use? (more…)

Strong-name Unsigned Nothings

2008/03/18

A while back I wrote about how to access internal methods in unit tests. When I actually tried to do it, I got the following error message:

error CS1726: Friend assembly reference 'MyDllTests' is invalid. Strong-name signed assemblies must specify a public key in their InternalsVisibleTo declarations. (more…)
