Kids like it when you set and enforce rules.

No.

I wanted a way to put my LS-P5 to the test, and fortunately the Royal College of Music is just around the corner, and they have some amazing free concerts. I picked the first one I could attend - Kammarmusik kring slagverk, and was duly impressed by the percussion class and friends led by Joakim Anterot and Daniel Berg. For more Daniel Berg, you can listen to Arctic Nights on YouTube.

Good video is one thing, but if you really want immersion you need good sound. The LS-P5 from OM System (previously Olympus) is a small recorder with good quality sound, in a small package, for a nice price.

Until now, software has been designed. Every bit of it has been deliberately made just so. We talk about "architecting" and "building" software, much like you'd architect and build other civil engineering projects - houses, bridges, and roads.

In No Silver Bullet: Essence and Accidents of Software Engineering by Frederick P. Brooks, Jr. we first meet another metaphor: that of growing software.

Nature's own color festival has made it to my 'hoods.

The sunrise looked like it might be good, so I packed the camera and went out.

Autumn morning.

It's the long tail of summer - still warm, but every day is colder than the one before, and each sunset earlier than the previous.

While at the playground I found this Little Tikes Tap-a-Tune xylophone from 1985. Since I had my bike multi-tool with me, I decided to repair it. Some keys were stuck and some didn't make any sound when pressed.

Or maybe AnarCat.

The Gabrovo bypass road numbered 5004, cost about 77 million BGN, but delivers a beautiful driving experience and, I'd say, is something for Atlas Obscura.

I woke up early and grabbed the camera.

September came with glowing red sunsets.

While thinking about ways to get Visti off Google App Engine to keep my monthly costs predictable I ran into Runor, and realized that all my problems had been solved since December 3, 2020. Marco Bianchi has done a top-notch job with Runor, and the result is everything I wanted Visti to be - and I don't have to develop, maintain, or update it. I immediately shut down Visti and I think I'll have a glass of mead to celebrate the ten years it was up. Rest in peace, Visti, October 14, 2014 to August 30, 2025 - that's 3974 days.

Problem: baby likes to talk to grandma over video call, but the little one also presses every single button there is on the touchscreen, resulting in (at best) hanging up or (at worst) the phone being left in some indeterminate state.

Anyone who has done any computer-generated graphics has come in contact with the Mandelbrot set.

It's possible to raise the signal-to-noise ratio when imaging a static subject by taking several photos and averaging them. But how fast does the ratio improve?

Google App Engine supports multithreading, but only in a restricted form. In particular, all threads except the request thread must finish their work at within the request; and while there are exceptions if you run on a back-end instance, there are a lot of interesting things you can do in parallel on a front-end instance, such as multiple parallel datastore queries.

Due to the biggest solar flare that has come to earth in the last 19 to 20 years[*] we were treated to northern lights in Stockholm. Here seen from Granholmstoppen over Husby, Kista and Akalla.

Given that the Nikon D3200 has a 24.1 megapixel sensor, how do I get the most out of those pixels? In particular, what is the sharpest aperture for the Sigma 10-20mm?
