Brachypelma smithi: it's a girl

Before I went to the bed I checked on the Brachypelma smithi I keep and found it already out of its molt but still upside down. The molting process had started yesterday in the evening.

About 10 hours later I took another photo of this specimen. It was now right side up and moved when I opened the plastic container I keep it in.

In the afternoon I decided to determine the sex of this specimen. I made the molt slightly wet and let it rest for a while; a moist exuviae is much easier to manipulate. In order to take a good photo of the spermathecae, if present, I put the exuviae on a piece of paper and shone a light underneath the paper.

I used the macro lens I bought the 17th of June 2020, but with the LED ring light off, to take the above photo which is a 1:1 crop with some post processing in Pixelmator Version 3.9 Classic. The above photo clearly shows the spermathecae, which means that this specimen is female.

Announcing Perl 7

Perl 7.0 is going to be v5.32 but with different, saner, more modern defaults. You won’t have to enable most of the things you are already doing because they are enabled for you. The major version jump sets the boundary between how we have been doing things and what we can do in the future.

Emacs Server – Why and why not?

Unknown to many of us, under the hood emacs was designed as a client/server architecture; which means, Emacs core runs as a daemon and you attach clients to it. Normally, we run both when we type emacs, but the execution of both the client and the server is transparent to the user. Before you attempt to do something fancy, this architecture is somewhat limited to localhost (1), which means that you can’t quite “remote into” an emacs running on a different host. In a world where we have tmux, mosh, and other multiplexers and mobile connectivity technologies, there may not seem like there’s much room for running emacs as a server, but we will see some advantages to this approach.
