Internet Account Keeps Coming Back after deletion on MacOS · KK's Blog (fromkk)

Today I tried to delete an inactive Internet account on system preference. It was deleted successfully but come back again after 20 seconds. This drives me nuts.
I tried these methods, but none of them works.
Boot in safe mode, delete account. Delete record in ZACCOUNT table in ~/Library/Accounts/Accounts4.sqlite. Delete related items in Keychain Access APP. Later, RedHatDude’s answer in this post gives me a clue, it looks like a iCloud sync problem.

Enable C Extension for gensim on Windows · KK's Blog (fromkk)

These days, I’m working on some text classification works, and I use gensim ’s doc2vec function.
When using gensim, it shows this warning message:
C extension not loaded for Word2Vec, training will be slow.
I search this on Internet and found that gensim has rewrite some part of the code using cython rather than numpy to get better performance. A compiler is required to enable this feature.
I tried to install mingw and add it into the path, but it’s not working.

When a new key is added, python use i = hash(key) & mask where mask=table_size-1 to calculate which slot it should be placed. If the slot is occupied, CPython using a probing algorithm to find the empty slot to store new item.
