Por que não começar soma com o valor zero e evitar essa subtração?

@FAETHER
And what my comment above was about :) (The thread i linked was Thorvald's reply to that article really)


@joaomoreno you should check how you used to implement that provider. What I see is a signature of:

`provideTextContent(resource: URI): Promise<ITextModel | null> | null;`

and this error condition:

I don't think a different binary makes much of a difference to the point I was trying to make... My point is that the test shouldn't assume a binary exists on the system, it should either:

1) check if the binary exists and cancel the test if it doesn't, *OR*
2) provide a binary

I'm in favor of option 1, because it's simpler.  Option 2 would probably be doable by writing a Python based "nc" or "cat" like script, but it would be costlier to implement and harder to maintain.


Essa questão está igual a questão 2

I would recommend running a linter (eslint) on the JS bits. Lots of missing semicolons and other things a linter will catch (like `var` vs `let/const`).


Is this still going to be emphasized?  We want to give time to discuss this question and understand the different types of decision rules that can be represented.


Nice 👍 💯

Will the steps below still be expanded?  We need to explain the idea of regularization we can discuss the two hyperparameters.  One of the toy examples was designed to show the effects of L1 versus L2 regularization.


lldb-7.0 seems to be failing in all the build bots (at least those that have attempted a build so far). see e.g.

nothing is true


msgpack is faster than gob. I found the bottleneck of massive read case is `Encode()` than RTT of redis, so I tried to reduce the cost of it.
This branch is just for my experiment. It is better not to use it as it is.


looks like the builds require a c++11 capable compiler

Right - should have noticed the failure was in 3m and the fix was in cs. Sorry. Will open a bug so we don't forget about this.


We can make the code inside the Ninjas component more dynamic and not just hardcoded, by using props - which I'll be going over in the next commit.
