This can be very useful. I wonder what the plans are for supporting C apis, given that a lot of Python core libraries depend on C, in my neck of the woods numpy and scipy being the first contenders. There are long running projects http:&#x

How about Sympy, http://www.sympy.org , https://github.com/sympy/sympy . Not sure if "good", but seems reasonably popular on Github.

Every feature is in HEAD, behind a flag. Precisely because managing conflicts cannot be automated, relying on branching is unwise. With HEAD based development, you manually solve conflicts exactly once, when submitting to HEAD, then you nev

Every feature has a flag that you can turn on/off to your heart content. Releases are cut at head. No need to use the version control hammer to screw all the zippers.

It's highly likely that powerful interests [governments and big tech] can already silently listen on mobile phones and have a database of voice signatures so they know exactly who's talking and what. That being said, the Panoptico

There are two points here: A. Polynesians are definitely not "first South Americans", regardless at which date the conjectured sweet potato journey happened. Simply because the other South Americans we know of arrived about 15,000

Australians != Polynesians. Polynesian migrations are relatively recent, starting 3000BC ~ 1000BC from Taiwan. They got to New Zealand and Easter Island only about 1200 AD, which is only 300 years before Columbus. I don't recall any ev

I stand corrected. Looking at https://cloud.google.com/compute/docs/zones?hl=en , it seems that GCE has multiple zones in the same locale (region). I might have confused with Google's internal setup, which dur

Yes. Simple. There is code [interface implementations] and data [structs]. Elementary. Except that our industry went on a wild goose chase, declared that everything is an object and everything that isn't an object doesn't matter,

Every so often the optimizer does it wrong. Instead of reading query plans [new language] and adding a layer of hints [yet another language], how about having a language that allows you to specify the precise order when you eventually care,

It's a sizable issue for me. I write every piece of code several times: once to get a sense of the problem space, once to prepare it for review, once to incorporate feedback review and once to adapt it once a new customer has as simila

It's software, everything is possible :) It is fairly straightforward to add compile time information via a simple case class definition. There is still a dynamic type check that json matches the case class, but the spec of the structu

The API is great and very useful for Python coders. The Scala version uses strings to identify fields. Haven't run the example code, but it seems to essentially encode a form of run time type checks instead of compile time type checks.

I have found the opposite. Building things you don't need yet it's just increasing the mass of code that needs to change when the real requirements hit. It pays off to build software as simple as possible, and modify / genera
