Select count(*) takes a surprisingly long time, even on an indexed table. Apparently thus is because of the MVCC model and row count estimates are available to mitigate.

Are the newer ships more environmentally friendly? I'd assume only slightly because they're still burning bunker oil, only slightly more efficiently. Which I find perverse given the attention focused on car pollution.

Yes, I think we should work on a FAQ to introduce common ML concepts and their implementation in Keras. Any specific concept that you had trouble with?
Cool. It sounds dumb but just shaping the inputs was a problem for me. I wanted an LSTM/RNN but epochs, batches and recurring sequences didn't click together for me. I also had trouble plotting the learning curves.

Congratulations on hitting 1.0, Keras really looks like the way forward for python ML. I tried to use Keras after doing Andrew Ng's Coursera course but found that I just couldn't connect the dots from what I'd learned on the course to the concepts assumed familiar by the keras documentation though.

I agree with you completely. The idea of a single language to rule the entire system is brilliant, and is something I wish others would consider putting their attention on - i.e. distro builders who compose a "Lua-only" stack, or a "Python-only" stack, and so on.. well, such things exist in Dockerland easily enough these days, but one wonder what it would be like if the 'modern desktop OSes' had this hit-one-key-and-access-code-anywhere mentality .. it has so much appeal over the current worm bucket o' mystery that is the modern OS 'distribution'/'package'/'bundle'/'module collection' ..
wasn't that the idea with OLPC Sugar [http://wiki.laptop.org/go/Sugar]?
The whole desktop and apps in python and hackable.

Unfortunately, being incorporated in Malta just screams "shady business" - at least here in Slovenia where such companies belonging to questionable characters are constantly in the news.
It's interesting to hear that having recently experienced the wholehearted enforcement of KYC rules and general efforts avoid/shed that reputation.

The going rate for setting up an Irish company is around €250, and mine only took a few days.
Getting an Irish bank account is painful though, and that's with me being Irish in Ireland. I wouldn't try it from Portugal - though presumably you could use a local bank.
This is worth consideration too.
Getting a bank account can be difficult.

How long before these vacuous AI assistants will be useful in the real world?
* "Siri, check if there are better deals than renewing my car insurance with current provider."
* "Cortana, book my brother a flight from Milan to Toulouse on Monday, and don't forget to check budget airlines that aren't on expedia."
* "Alexa, change my phone contract to the new daysaver tariff."
Telling me it's raining outside or being able to make a restaurant booking in a handful of places in NYC is just not interesting^W AI.
Context and identity seem to be major missing ingredients.
Why would you ever do that? You'd end up a bunch of unreadable rust code wrapped in a gigantic unsafe {} block.
The LSTM would be trained against an existing high quality Rust code base and it's IR; so I wouldn't expect a bunch of unsafe literal translations.
Whether the C side IR has enough debug metadata or could be annotated automatically would be the make or break.
I was just recently wondering if an LSTM neural net could be trained as a decent decompiler from LLVM IR to Rust source. Feed that with Clang output of an established OS and coreutils(i was thinking minix3 but maybe seL4) and get a working if not necessarily idiomatic Rust OS. Refactor at leisure.
