It is beginning to infiltrate
industry at a fast rate, and it’s a challenge for designers and also engineers.
I wondered when a weakness will be revealed. Then I stomped on an article
talking about harm in using LED technology. It looks like this magical
technology is not so magical and eco-friendly.<p>A new study from the University of California indicates that LED lights contain
toxic metals, and should be produced, used and disposed of carefully. Besides
the lead and nickel, the bulbs and their associated parts were also found to
contain arsenic, copper, and other metals that have been linked to different
cancers, neurological damage, kidney disease, hypertension, skin rashes and
other illnesses in humans, and to ecological damage in waterways.<p>Since then, I haven’t yet found any regulation for disposal of LED lights or any
other regulation or standard. This might be a problem in the future. And it is a
massive drawback. This might have quite an impact on consumer market.<p>Nevertheless, there is a potential, and I am sure the market will adapt. I also
hope I will be reading documents regarding solution for this concern soon.<p><strong>Additional resources:</strong><ul><li><a href="http://ezinearticles.com/?Recycling-and-Disposal-of-Light-Bulbs&id=1091304">Recycling and Disposal of Light Bulbs</a><li><a href=http://www.ehow.com/how_7483442_dispose-lowenergy-light-bulb.html>How to Dispose of a Low-Energy Light Bulb</a></ul></div></article></main><section><hr><h2>Posts from blogs I follow around the net</h2><ul><li><a href=https://chotrin.org/writing/2023-10-20.html target=_blank rel=noopener>OpenBSD upgrade and fall things.</a><div>Been AFK for a bit.

There’s no shame in that. Yes, there is documentation, code to be
read, and debuggers to be used. But sometimes you just need to “see”
