No affiliation with the service. Just a happy user. Great UI. 2FA implementation with TOTP, app passwords and backup codes. Custom domains support SPF and DKIM. Very cheap pricing at $10/year for "all-you-can-eat" with some soft limits. Looks like a one-person project but developer has been active with regular updates on the both the service status and issue tracker.
Keras still has CNTK and Theano backends in addition to Tensorflow. Given that both frameworks are not being developed anymore, is there any point in maintaining those backends in the future?
F# language has a concept called "computation expressions" which are related to monads. They are also sometimes called workflows. But the article is using "workflow" in the more common language way which was confusing to me at first.
I loved OCaml as well but the lack of libraries pushed me to another ML variant: F# on .net platform. With .net core and F# tooling around it gradually maturing, it is a solid cross-platform functional language.
