I know someone who works in UHC’s appeals department. They do in fact overturn the majority of denials which are appealed. Might just be selection bias, though, with only those who have the least ambiguous situations bothering to appeal.

Hash tables are often used behind the scenes. dicts and sets in python both utilize hash tables internally, for example.

Firefox now includes safeguards to prevent sites from abusing the history API by generating excessive history entries, which can make navigating with the back and forward buttons difficult by cluttering the history. This intervention ensures that such entries, unless interacted with by the user, are skipped when using the back and forward buttons.

Nice

I’ll vouch for Proton. The recent controversy wasn’t great but it’s also a single negative incident for a company that has otherwise had a pretty stellar track record. I recommend reading his responses in the reddit AMA he did after the incident. I still think he’s a fool, but I don’t think he’s fascist or that there’s any reason at all to doubt the privacy, security, or direction of the company, which is both partly open source and regularly audited.

I’ve been using ProtonMail for probably around 7 years now and it’s been great.
