Speaking at dev.Objective()

I'm very pleased to announce that I've been selected to speak at dev.Objective(), which is coming up in Minneapolis (more specifically Bloomington), MN on May 12-15. (And yes, if the conference name seems vaguely familiar this is the evolution of the former cf.Objective() conference.)

My session is Naked and Afraid: Mobile Offline Access to Emergency Data, in which I'll be discussing how to build cross-platform mobile apps that sync and cache data so you can have access to it even if the Internet and mobile networks are down.

Since I quit doing CFML/ColdFusion several years ago and moved over to Python I stopped speaking at and attending cf.Objective(), but it's a fantastic conference so I'm excited to be making my way back. It's going to be really great to reconnect with a lot of people I haven't seen in quite a while.

If you're a web developer looking for a great conference with a lot of great sessions presented by world-class speakers this is it! Ho…

When I tried to connect from the networking charm (I think that's what they call the bar on the right-hand side of the screen) it would hang for a while but never connect, and after that happened when I clicked on the networking icon on the lower right the charm bar wouldn't even come back.

I figured it might be a driver issue so I opened up Device Manager and sure enough, under the network adapters section there were yellow exclamation marks next to every one of the WAN Miniports that show up after you try to connect to a VPN.

I found varying reports of how to fix the problem but here's what worked for me.

Try to connect to a VPN that will cause things to error out (the WAN Miniports didn't even show up in the network adapter list for me until I did this)Open Device ManagerExpand "Network adapters"Right…
