Although the fire released a lot of lead, making it necessary for researchers to don protective clothing and abide by procedures to avoid lead toxicity

This seems to be a common misconception --- lead has a high boiling point and (unlike e.g. mercury) basically zero vapour pressure at atmospheric temperatures and pressure. To be around while the fire was still burning would be dangerous, but after it's cool it won't be releasing any lead vapours. Those working in electronics will know this.


Gaseuous lead condenses on all cooler surfaces, but due to the high surface tension of liquid lead, doesn't bond to those surfaces. Leading to a cover of mobile lead dust over everything, which makes breathing dangerous. Touching it is also not that healthy because the dust has a high surface area, is already oxidized and therefore too easy to dissolve in bodily fluids and sweat.

The situation is of course dependent on a whole lot of boiling lead having been around, solid cold lead doesn't really produce a lot of dust if you leave it alone.


I think the main concern is breathing in lead dust. Also, since it's so soft, it rubs off easily and can contaminate other things. I've worked with lead, and my bright orange gloves were black with lead pretty quickly.


Absolutely infuriating mobile site behavior- try scrolling down just a little, site rips the content across the screen and inserts a garish title bar. Scroll back up just a line and the huge opening title graphic slams down from above. Can I just read this?


Before Mozilla's rewrite of Firefox, I had this great addon installed that just hides all floating elements. Great for blocking stalking consent forms and title bars, or even worse, those social sharing bars at the bottom of the article.

Ublock origin's element zapper works to kill the title bar, and reader mode is also available. Workarounds for bad site design, I know, but at least I can read the text without distractions.

Sadly, I'm still waiting on Mozilla to reopen all addons back to me. I know I can use the nightly version of the browser and a custom addon collection to force the installation of the addon, but I don't want the instability that comes with it. I'm already running the beta so I can have my about:config with all the stability issues that come with it.


I think there's a business case for building a machine learning baseed tool that separates content from crap automatically.

And it's not like there's a shortage of quasi-labeled training data.


reader-view in firefox already does this. strips everything except the content
