“Engineers have invented a new way to remove health-harming ‘forever chemicals’ from water – using 3D printing.

Researchers at the University of Bath say their method, using ceramic-infused lattices (or ‘monoliths’), removes at least 75% of perfluorooctanoic acid (PFOA), one of the most common perfluoroalkyl and polyfluoroalkyl substance (PFAS), from water, and could become an important tool in future efforts to eliminate the chemicals from water supplies.

Their findings were published this week in The Chemical Engineering Journal.”

[…]

“Testing of the monoliths has surprisingly shown they have become more effective under repeated use – they undergo high-temperature thermal ‘regeneration’ treatment after each use. This is something the researchers are keen to understand more fully with further experimentation.”

If a website could be sure none of their users are malicious/bots and all of the users are perfectly rational and virtuous then public or private voting wouldn't matter either way. That being nearly impossible, why not a reputation based system like Stack Exchange? Only when an account meets certain requirements they can vote.

To boot, on the website tweakers.net one can actually vote -1, …, +3.

  • +3: “Spotlight comments are of such high quality and substantive value that they clearly stand out above the rest”
  • +2: “Informative and interesting comments that are a useful addition to the discussion in an on-topic thread or the information in the article”
  • +1: “Nice on-topic responses with knowledge that is common knowledge”
  • +0: “Comments that do not contain a relevant contribution, but are posted with good intentions”
  • -1: “Flamebaits, trolls, misplaced jokes, unnecessarily hurtful comments and other comments that violate our terms and conditions or house rules”

What if we could avoid typing “+1” with upvotes? ;)

What does the acronym SO stand for?

Fair enough. But a workaround that I have implemented before my previous “Reddit nuke” was saving all my most valuable answers and hosting them on my own website. What I would do now is just replacing all my comments with a link to my website: POSSE, Publish (on your) Own Site, Syndicate Elsewhere. Well, almost POSSE, because I'd be removing the actual content from Reddit.

Do the advantages of deleting one's entire Reddit history outweigh the disadvantages?

I have previously nuked my first Reddit account because it felt satisfactory to be completely detached from a platform one considers unethical/bad. Though, I have garnered quite some history on a second account—because Duty Calls*, of course—and I'm considering doing the same.

However, I don't want to do it impulsively. I think I might be blind to some disadvantages. What do you think?

Unfortunate indeed.

Had it happen to me too. They'll refund you for this. Just be polite when asking for it.

My review on the Play Store: “Premium is a scam. Hides likes which come from all over the world (clickfarms?) even though I set my radius to 5 km. But of course they only show you the fake likes (all of them) after one pays for premium.”

Thanks for the share, had no idea. It felt so nice that I already added two contributions to OpenStreetMap.

Fair point. I should've made the distinction. But in any case, nuclear power plants aren't bad.
