Seniors are survivors. Just sayin’ 😄

“I am 83, in the McDonald's drive-through the young lady behind me honked, & was mouthing off ‘cause I was taking too long. At the 1st window I paid for her order. The cashier told her. As we moved she waved to me and mouthed "Thank you”, embarrassed that I repaid rudeness with kindness. At the 2nd window I showed both receipts and took her food too. Now she has to go back end & start over again.

Don’t honk at seniors. They’ve been around a long time.”

The CSS Zen Garden is 20 today.
http://www.csszengarden.com/

It was about 9pm or so in Vancouver twenty years ago today, where I spun up an FTP connection and uploaded a handful of files to a server. I didn’t expect what happened next.

My intent was creating a site that proved CSS was a better way to design and build for the web than the mess of fonts and table tags the industry was dependent on up till that point. I figured a handful of the folks already into CSS at the time would find it neat, maybe a few other people would make an attempt at submitting, and it might prove to be a fun talking point for a few months.

What I didn’t see was how effectively it proved the point, and how revelatory that would be to the wider industry who weren’t using CSS yet. I mean I always dreamed it might reach a wider audience, but I never expected it to blow up early and remain relevant for as long as it did.

The designs it contains span a formative period of web design and development and most are of that era, while the industry has continued advancing beyond the ideals of 2003. But I keep it alive not just as an early web milestone, but also because it continues on as a reference for web curriculums and those joining the industry every day who get to experience that same aha moment the rest of us did many many years ago.

It’s no exaggeration to say that this one site launched not just my own career, but the careers of many of the contributors who are still prominent in the industry today. It remains my most significant mark on an industry I still work within today, and I still feel the pride of managing to create something that helped change the trajectory of the web for the better.

CSS Zen Garden: The Beauty of CSS Design

A demonstration of what can be accomplished visually through CSS-based design.

I think I may have found something that can replace #openscad for me, and make good use of #python and #jupyter to boot. Needs a bit more experimentation before I can commit to using it for precision modeling and #3dprinting.

Wow! Sovol just released the source files for the SV06 printer parts! https://github.com/Sovol3d/SV06-Fully-Open-Source

Can't wait to see the mods coming, and maybe make some myself!

And some generic remarks - not specific for the SV06, but it was my first exposure to them:
- I am now firmly in camp direct-drive!
- Tune linear advance for every filament, it can make a big difference in print quality

Now I'm hoping that they'll update their firmware to Marlin 2.1.2. so we can use basic resonance compensation!

- I've noticed slight heat-creep on PETG prints at 235C after ~16 hours. While printing everything is fine, but the hotend is a bit stuck the next day. Solution is to amend to extrude 100mm filament after the nozzle heater is off.
- The hotend and gears are easy to reach for common problems
- The bed magnet is weak, warping the whole flex-sheet upwards in the corner when printing large parts diagonal over the printbed.
- The linear rails and the PSU fan is a little loud for home-office use
