In the morning my brother and I went to the invertebrate show in
Harmelen. Near the entry my brother spotted a black scorpion. Not the
animal, but a large chili pepper plant. As he loves to grow his own
peppers he was soon in a conversation with the owner of the plant, and
even managed to get two peppers so he could grow his own plants from
Next, we walked around and admired the invertebrates on display and
for sale. A lot of scorpion and tarantula species I only knew from
photographs seen on the Internet, so it was very cool to see them in
Before we left I talked with Jeroen Kooijman about his book
Schorpioenen - hun ware verhaal (Scorpions - their true story). He
has been working on it for 3 years and it looks fantastic. Of course I
bought a signed copy.
The history and legacy of jQuery
But in the past several years, jQuery’s status as the number one
tool for web development has diminished. Let’s take a look at why
jQuery became popular, why it has somewhat fallen out of favor, and
when it would still be a good choice for a modern website.
In the afternoon my mother and I went to a flower exposition inside
the local church. It was quite a large exposition and I took several
Rewriting CommonMark Nodes issue
In the evening I added the CommonMark node rewriting code to the
tumbelog program only to find out that the solution I wrote yesterday

Stop Infinite Scrolling on Your Website - Now!
Do people love infinite scrolling on the websites they visit or are
they fine with clicking on ‘Read more’ or ‘View more?’ Infinite
scrolling eliminates the need for pagination which is the process of
separating digital content into different pages. Here’s my view on
infinite scrolling and why it is a recipe for disaster.
In the evening I found out how to rewrite nodes in an abstract syntax
tree generated by the Perl CommonMark parser without ending up with
corrupted nodes. Of course I had to blog about this:
Rewriting CommonMark Nodes in
The code given will be used in an upcoming version of tumblelog to

Just after midnight I started in She Has Her Mother's Laugh by Carl
Zimmer. I read the first pages, and so far I like it a lot.
New Evidence of the Asteroid That Killed Off the Dinosaurs
Drilling into the seafloor off Mexico, scientists have extracted a
unique geologic record of the single worst day in the history of
life on Earth, when a city-sized asteroid smashed into the planet 65
million years ago, wiping out the dinosaurs and three-quarters of
all other life.
At 7pm I started to watch the Apple Special Event. While I rarely play
games on the computer I am interested in Apple Arcade, and I enjoyed
watching the game Shinsekai: Into the Depths by Capcom; very nicely made.
Next, a new iPad was announced: 7th generation with a 10.2"
retina display. As my iPad Air 2 got stolen in a break in into our
house over a year ago I have been waiting for a new model to be
released. And it has, so a new iPad has been moved to the top of my
While I am still happy with my iPhone 5 I know there will be a time in
the future I have to replace it so I also looked forward to the
presentation of the iPhone 11.
I was very impressed with the photographic capabilities of the new
phone, especially night mode. And the game that was shown running on
it, Pascal's Wager, looks fantastic.

We are volunteers who make and take care of the Python programming
