When I see people writing on their blog “iPad this, iPad thatβ¦ on iPadOS 15 beta” it often is about the iPad Pro. I’m still sporting the “iPad budget”, which has little use for the new enhancements. Sorry, I can’t afford being a Pro user. More power to you if you can. π

While seeing almost no visitors per day on my self-hosted blog, I have to remind myself its purpose. Well, Iβm doing what I set out to do, sorta, despite distractions and setbacks.
So⦠Am I doing my chores to have something to blog about, or do I blog to celebrate completion?

Data Serialization β The Hitchhiker’s Guide to Python Always handy to know if you have rolled your own, and wondered if this is a solved solution. In fact, there are several solutions. π¨βπ»

Nature seemed a bit out of control, but luckily enough people had gone over this path that I could see its way, barely. Because of the heat, I came across no one (human), though I saw lots of young rabbits hopping around.

Pass 1 of a 2-pass assembler in Pythonista 3 seems to work for a 256 times 8-bit word memory. I hadn’t done that before, so it’s a win in my book π¨βπ»

While reading all about how “modern” computers do all kinds of tricks to load executable code on the fly, doing this on an 1980s 8-bit computer seems rather cool, yet overkill. Though, combining built-in ROM routines and Basic with external executable modules is appealing π¨βπ»

Finding academic books and articles electronically is quite a hassle. Some sites want you to pay for it, others seem to insist on an .edu e-mail address. Talk about walled academic gardens! π¨βπ Luckily, I found some free ones, now freshly pressed on my iPadβπ π§©β β― π§Ή

I see people claiming that, being fully vaccinated, the pandemic is over. The WHO declared the current pandemic and has yet to declare it being “over.β I see a lot of red on the transmission chart, including most Western countries. More scary are the light blue areas (no cases).

Watching PDP-11 Assembly Lesson 3 - Conditions, branches and loops - YouTube to learn about how to do assembly language for this (then) groundbreaking computer. π¨βπ» πβπ₯

Clearly, π±βπ» β π¨βπ»! If it were true, πββ¬ would rule the π. Or maybe they already do, and we just don’t know it.

Before I write a basic assembler in Pythonista 3, I should be able to process a source file and output the result into an object file. Here I reversed each word in a text file. It’s very basic, doesn’t take into account punctuation, but it works, and that’s enough. π¨βπ»

I think I should implement this one-pass and two-pass assembler in Pythonista 3 on iPad. The project is from the book Assemblers and Loaders. π¨βπ»

Iβm happy with my tiny town garden. When I came here, the previous renter had left it in a poor state. I think itβs quite an improvement. They used it as a rubbish dump, for burying larger items of trash. I dug up 240 liters or so, replaced it with garden soil. π πΈ

Writing a print file extension in Pythonista 3 seemed so easyβ¦ I had to learn a few new things, so, in the end, it’s all good. π¨βπ»

π Someone had painted the wooden door frame of my bathroom with wall paint π€ͺ So it needs two layers of paint primer. I couldnβt sand off the wall paint, since I donβt know how remove the door, and, more importantly, how to properly put it back into the frame.

Todayβs ππΆπΌπ (900 m : 100 m) went surprisingly easy. Also special was that at some point there was no traffic in sight, while around 4 pm itβs usually pretty busy with commuting cars. Didnβt last long, though.

Went shopping for π improvement. Some paint and primer, degreaser, lacquer roller and brush, tape, system to catch the mail from mashing cat teeth. Not much, still 160 euros π£

I thought my body deserved an interval training for my π It’s an acquired taste, I believe. I ran 200 m pretty hard, eased down 200 m, and did that five times. I needed 4:56 min for that fast-paced kilometer.
