cosinetau commented on Gmail will no longer support checking emails from third-party accounts via POP support.google.com/mail/a... · Posted by u/sumanep

The linked page says that Gmail is discontinuing support for the old Post Office Protocol in favor of IMAP. Nobody has used POP much in years. Decades, maybe.

IMAP can check for mail without downloading. But apparently Gmail doesn't support that.

You can do this the other way round. Use a local email client such as Thunderbird on desktop or FastMail on Android to check Gmail and any other email accounts you have.

Writing in as a current POP user. I use it to import email every day.

Amazing story. Why post on LinkedIn though? I'm not angry, just disappointed.

Prop 13 prevents new property tax without a direct referendum.

Without new revenue streams, gifted programs were affordable for school districts until they were not.

I'm going to give this a go, I've been self studying linear algebra, and there are certain questions that I can't seem to find good answers or explanations to online that ChatGPT or Claude cannot answer sufficiently. The one concern I have with this, is the async nature of it. One of the reasons I like using ChatGPT or Claude (or a real human if I can find one) to learn is because I can ask clarifying questions and try to relate what they're saying in real time to another concept I'm familiar with. Curious to try it out but I think that an important part of making the videos good is that the student / learning needs to provide a good prompt so that the response can be customized to directly address their area of confusion.

Hi - math student here too. Have you asked any image AIs for graphical representations of these Linear Algebra problems? How did those attempts go?

Asking because visualizing the problem scenarios was something that did not come right away for me, and I had to spend a lot of time in the tutoring center to build it. I believe the right prompt might yield the right thing.
