Aphonopelma seemanni molting

In the evening, when checking upon the Aphonopelma seemanni I keep I noticed that it was upside down in its burrow. This means the tarantula is going through ecdysis; the shedding of its old exoskeleton.

The tarantula has been restless for about a week or so, getting out of its burrow entirely, and moving around a bit. Maybe it was looking for a better spot to moult? Or maybe because the room temperature exceeded 30°C (86°F) now and then?

In the above photo you can see the silk the tarantula has spun to close off the entry to its burrow.

If all goes well I expect to be able to collect an exuviae, the cast off exoskeleton, tomorrow, which can be used to determine the sex of the tarantula which I don't know at this time of writing. I hope female as females live much longer compared to males.

How does SQLite work? Part 1: pages!

Building a high performance JSON parser

JSON is important, damn near everything that we do as programmers or operators involves JSON at some point. JSON decoding is expensive, if your product talks JSON then performance of marshalling data in and out of JSON is important. This is a talk about designing an efficient replacement for encoding/json.Decoder.
