Dunno what these #bicycle tires are made of, but they are absolutely indestructible. Thousands of kilometers and not a single puncture. Highly recommended! “Schwalbe Marathon Plus Tour”

I read that the lifespan of modern batteries can be tripled by proper use
The max cap goes down by 1% every few days if you regularly let you iPhone (or any other phone I assume) discharge down to ca 🪫10% or less
In contrast, I tried to never go below 🔋20% charge, and this is my 5 years old one

We’ve seen more students and recent graduates visiting @rejobs.org lately, specifically looking for #internships in #renewables.
So I made a landing page for them: rejobs.org/en/for-stude...

If you're a natural sucker on social media as I am, but really want to stick to it, try @buffer.com
The main difference for me is that I can split the whole process into writing and posting, and do it in batches. Very effective

Schema.org support is indeed essential for job boards! But how do you check for the jobPosting schema? Your tool says "No JobPosting schemas found" for rejobs.org/en/renewable... while Google says our schema is OK

Hiked Sněžka mountain in the Krkonoše national park today. Spring in full swing, birds busy building nests 🪺 and pines and moss of all shades of green producing magical scents
But of course there was this one guy with his drone on the hilltop, ruining it for everyone 🦟
Views were stunning though

Rereading David Lynch’s Catching the Big Fish. He likens the mind to an ocean: surface-level thoughts are like small waves, while deeper thoughts—big ideas, or “big fish”—reside in the depths. Lynch argues that transcendental meditation allows to dive deep, where the richest, profound ideas exist
