Just before 4pm I noticed that the Caribena versicolor I keep had
molted for the first time in my care. In the early afternoon I had
added water to the enclosures of each of the ten tarantulas I keep,
mostly slings. And I guess the increase in humidity triggered the
molting process in the little spider. Or maybe it was just ready.

After I had taken two photos with my iPhone 5 with a LED ring light
plus macro lens I
noticed a small mealworm crawling around in the enclosure. I always
crush the head of mealworms prior to feeding them to my spiders, but I
guess I didn't do it right with this one.
As the Caribena versicolor shouldn't eat for at least a week after
molting I removed the mealworm and tried to feed it to the Hapalopus
sp. Colombia "large" I keep. This spider also molted recently; I found
an exuviae with it the 21st of this month. But it was not
interested in eating the small mealworm.

In the end I fed the small mealworm to the Chromatopelma
cyaneopubescens, which detected the wriggling prey item and picked it
up to eat it.
Recently the topic of generating random-looking coupon codes and
other strings came up on internal chat. My go-to for something like
that is always this
solution based on
Feistel networks, which I didn’t think was terribly obscure. But I
was surprised when nobody else seemed to recognize it, so maybe it
is.

I was making a quick project that require to scrape some information
from a
website. BeautifulSoup
is the library of choice.
Download takes 1-2 seconds per page, with high network latency
because the server is in US and I am in London.
After writing the downloader, it takes more like 4-5 seconds per
page, which is noticeably slow. How come? Could it be that large
HTML is slow to parse?
In the evening I noticed that the Pterinochilus murinus Red Color
Form (RFC) I keep was out in the open, eating a mealworm that I had
given to it earlier. Normally it eats inside its burrow, but now it
was outside!

I carefully moved the enclosure; a plastic container, and moved the
clips away from the lid. Next, I got my iPhone 5 ready with a LED ring light
and a macro lens.

While I carefully took several photos the tarantula moved around a
bit while holding its prey.
The spider has grown and changed a lot since it arrived at our
house. As far as I know
it has molted once
while in my care.
