    That depends on why the new round exists. It may simply be that the initial investment was traunched, and that it was always expected that no profit could be made by this point, but the investors still wanted a check point to make sure things were developing on track.

    Swift can guarantee data-race freedom, in exactly the same way that C and C++ can - by using the normal threading and locking primitives you get from the OS's libraries. It even ships with a more user friendly library for doing this (GCD) than most OSes provide.

    And swift absolutely does not require thread safe ref counting. Swift has both value types and reference types. Value types are passed by value (what a surprise), and include non-ref-counted pointer types. All you need do to avoid ref counting is to not use the word "class" in your program, and instead stick to "struct".

    Neither of these are impediments to system programming.

    Usually it's a case of needing to understand the actual use case in order to be able to provide alternate options.

    Usually it means "The thing you're trying to do is dumb for a number of reasons, but since you haven't described what the *actual* goal is, but instead only what a possible implementation might look like, it's impossible to tell you why it's dumb and what a better choice is."

    Concurrency/parallelism primitives was available through extensions (like posix threads, locks etc.). Those were available because, as native languages, C and C++ can make use of (inline) assembly and anything supported by ISA. Try that on interpreted/JIT-ed language.

    Yes - the point I'm making is that these are all equally available in Swift. All C APIs are available without any modification in Swift.

    No other modern language is capable of safety and is low level enough. I saw one comment here asking why no swift, well for starters it has no concurrency or parallelism primitives which are a necessity for a systems language. Certainly for whatever language you want to write a browser in...

    That seems like a strange assertion to make given that C has, and C++ until recently had no concurrency or parallelism primitives, and are the de-facto systems programming languages at the moment.

    It also seems like a strange assertion when Swift by default ships with Grand Central Dispatch, which gives it strong concurrency and parallelism support.

    The issue with swift as a systems programming language is that its compiler output is too magical. Several of its features can cause weird and unexpected perf implications when used in subtly different ways. For example, it's generics implementation can end up compiling down to either fully dynamic dispatch, or just normal C function calls depending on whether the compiler analysis could figure out which types you were using, when, and how often.

    This is a pretty common requirement in the western world. The US is the only western country I'm aware of in which there's not a law against advertising an item as on sale when it's never actually been sold at a higher price.

    In the UK (and most of Europe) for example, all price cuts must be advertised as being cut from a different price that you have sold the item at for a continuous 30 day period.

  12. With today's cars it's not out of scope, but it's annoying - you'd need to charge even in the highest range of them (315 miles in a P100D, make that 270 in the winter). With a supercharger the time to charge than missing 120 miles is going to be about half an hour.

    The good news is that with this samsung battery, you wouldn't need to charge, but even if you did, with charge point's new 400kW chargers you'd be able to charge enough for your *whole* trip in 15 minutes. In the summer, make that 10 minutes.
