Yeah performance counters

I like the coins idea. I don't subscribe because I know I'll forget about it and it will turn into a recurring charge on my credit card. But I would buy $10 of coins, knowing the paywall just comes back if I don't buy more, and if I lose interest it won't keep costing me anything.

When I see the "$1 introductory offer" I just think they are trying to trick me.

$13/month is less than many of those sites cost individually, but I get them all for that price?

A lot of it went into V8 too.

I'm actually pretty surprised if the JVM uses malloc to allocate the heap. V8 uses mmap, never malloc.

Larry should be remembered for the development of "patch" more than perl. Without the concept of fuzzily applying patches to modified source files you can't have "git rebase" or "git merge".

The syntax problems are just surface. There are some real problems underneath:

Poor performance of the single implementation.

A single implementation.

Leaky ref counted GC, but 'luckily' the syntax for references is so clunky that nobody does anything complicated enough that it really matters.

Bolted on object oriented features that never got the love they needed at a time when oo languages were sweeping the world.

Most of the wizards decamping to a new language (Perl6) that was 'developed' for years without an actual implementation to keep them grounded.

Nice!

Why malloc? Surely this is an on-heap object, not malloc allocated?

Yeah if you ever wondered why the fields in a lot of Posix APIs have names with prefixes like tm_sec and tm_usec it's because of this misfeature of early C.

You could always manually build the same thing as lambda with a class and you had the same problem.

The C++ GC is not for V8 code, it's for the users of the V8 API eg. Chrome (Blink). It's not being used for big internal systems like the compilers or GC.

V8 has its first module in Rust and I'm sure more are coming, but it's not necessarily an easy integration.

JS is a GCed language. Are there good examples of Rust interacting well with a GCed language runtime where it is able to free unreachable cross domain pointer cycles? Like a JS object that has a reference to a Rust object, which itself has a reference to a JS object. Add more steps and hopefully you can see that collecting such cycles is a hard problem. This is the problem the C++ GC solves.

By the way you can't always break cycles with weak pointers. The browser standards have semantics you have to adhere to.

That sounds like a lot:

To help prevent vitamin D toxicity, don't take more than 4,000 international units (IU) a day of vitamin D unless your healthcare professional tells you to. Most adults need only 600 IU of vitamin D a day https://www.mayoclinic.org/healthy-lifestyle/nutrition-and-h...

Most vitamins are a waste of time and money, some are even harmful[1], but there are a lot of people with D deficiency, especially in winter[2].

[Citation needed] for a pesticide connection.

Unless you are an insect, most pesticides are harmless for you. And for those that are not, nobody has proved a connection to allergies.

Eating peanuts reduces allergies, but getting peanuts on your skin increases allergies.
