I've recently developed a webapp with pure go, session handling from beego and sql support by go-sqlite3 from mattn. Right after the I've coded the first method that needed to make more than one db access I've got the following error:

Authenticate at AppEngine dev server
2013-11-24
Got a webapp in Googles AppEngine for a restricted user group? Enabe login required in the app.yaml and the AppEngine redirects the first access to a secured area to a login page. For productive running applications this requires to log in with a Google account but for the dev server it means only one (or two when admin privilege are required) clicks to get in the webapp. Things get complicated when it is a HTML 5 webapp with a RESTful API as a backend and an Android app should access the backend. For the production Nick Johnson has written a nice tutorial. Just don't try to replace localhost in https://yourapp.appspot.com/_ah/login?continue=http://localhost/&auth= with something meaningful. localhost is required here. But running a development version of an app against a live system isn't fun. Life will be much more easier using the dev server that is already installed for the backend.

Go revised: http handling

Go revised: RAM usage
2013-04-02
In the last post I've written about the file size. Of course disk
usage isn't the only measurement and so I wanted to add some
figures about RAM usage. The last article grow in length and it
turned out to be very complicated to provide those figures so that
I decided to give it an extra post.

Go revised: File size
2013-04-01
In this post I will talk about the file size of programs written
with Go. The compiled programs were very large and it was
interesting to see what gccgo brought into the issue.
