In the eyes of the neoliberal, you're only supposed to use identity politics to attack your enemy, not as a means of stating basic facts such as she's Italy's first female PM.

nit: she is the head of the party that received most votes. She will probably be prime minister, but for now no government was proposed to the president, even the new parliament will not start for another week

Hmm, this definition reads a bit wrong:

  @app.task((weekly.on("Mon") | weekly.on("Sat")) & time_of_day.after("10:00"))
  def do_twice_a_week_after_ten():

Expression reads Monday or Saturday, yet its meaning is Monday and Sunday according to function name.

andijcr · 3 years ago

if you take it as a boolean test it makes sense. it will be true for any timepoint that is after ten and is either on monday or saturday

If it's a useful and helpful tool (and I assume it is from what you've said), what's the problem? It's not as though the existing tool is suddenly going to stop working.

Do you mean "what's the problem with using the last available package of sourcetrail?"? Nothing, I'm using it. eventually, in some timeframe, the compiled package will stop be installable in a new system, or the unrecognized language features will be too many, which is sad.

Really sad to read this. sourcetrail helped me to understand a foreign codebase when I started my last job. The ability to navigate who-calls-who and who-implements-who back and forth is invaluable, and the search bar is fantastic. This morning I woke up and fantasized about forking the project to keep it alive, but I understand that the work behind it is too much to keep it as a side project.

Yet, gravity is strong enough to initiate nuclear fusion at the core of stars, or create black holes... That 10^36 argument is non sensical to me.

andijcr · 4 years ago

it is strong enough at the scale of a star, on earth my foot electromagnetic repulsion against the floor is enough to counteract all of the planet pull

andijcr commented on The Swift Array Design (2014) github.com/apple/swift/bl... · Posted by u/mpweiher

s3cur3 · 4 years ago

Swift's Array type is just so well designed. It's a delight to use.

Two things stood out to me here as being really nice for someone coming from C++:

- Implicit upcasting to convert `[Derived]` to `[Base]` in O(1).

- Checked conversions convert `[T]` to `[U]?` in O(N) via `a as [U]` in O(n).

These are both operations I've manually written the C++ code to do, because there's no ergonomic way to do it with `std::vector`.

andijcr · 4 years ago

for the first one, there is no direct equivalent, but you can directly loop over any [Derived] collection as a reference to [Base]

You seem pretty set in your choice already, just looking for confirmation. what's stopping you?

karma_fountain · 5 years ago

Nice fix! It's been a while since I've done c++ so does the following code

  const auto elapsed = steady_clock::now() - start;
  if (elapsed > 10s) {

actually use a units quantifier on the 10, i.e. does 10s mean 10 seconds? Is that a library thing? Cool if so.

andijcr · 5 years ago

that's a user defined literal, a language feature: https://en.cppreference.com/w/cpp/language/user_literal

the std::chrono library reserved some suffixes (under std::literals::chrono_literals) for time units https://en.cppreference.com/w/cpp/symbol_index/chrono_litera...
