Invertebrate Show

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 seed.

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 real life.

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.

A Visit to a Flower Exposition

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 photos.

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 about also caused memory corruption.

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.

Rewriting CommonMark Nodes in Perl

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 Perl.

The code given will be used in an upcoming version of tumblelog to render images with a caption.

She Has Her Mother's Laugh: first pages

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.

Apple Special Event

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 wish list.

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.

Sunsetting Python 2

We are volunteers who make and take care of the Python programming language. We have decided that January 1, 2020, will be the day that we sunset Python 2. That means that we will not improve it anymore after that day, even if someone finds a security problem in it. You should upgrade to Python 3 as soon as you can.

A Memory Called Empire: Good

In the evening I finished A Memory Called Empire by Arkady Martine. Interesting world building and a good read; I look forward to a sequel.
