I fucking hate amazon like I've been bounced back and forth between like ten different webpages and chat thingies, none of which give me the option to just get a new one without sending back the old one...even when the options I choose specifically say nothing was even delivered
Okay finally managed to get a refund by trying all of the different options in the dialogue tree
I never thought I'd say this but...after using TypeScript and Python+mypy quite a bit recently, I'm starting to prefer union types and nullable types over tagged unions and optionals
The latter is definitely more elegant, but the former is so much nicer to write
@Simd That's impossible. There'll always be an overhead of spinning up the threads, distributing the work, and collecting it all together again. I've seen about 3× speedup.
@Adám I don't really understand what is happening physically in the chip in the "spinning up the threads" part. I get that distributing the work means copying from memory.
but if it's a shared memory problem there should be no copying needed
I've seen 5~6x speedup on a 8-core machine using rayon (a Rust library that automatically distributes work across multiple threads; usually the number of threads = number of physical cores)
It takes time to start a thread and assign work to it. And if the work is not distributed optimally, the time will be dominated by the thread finishing last
Assigning work can be done in many ways, but for example in rayon, there is a job queue and threads can push and pop units of work. Pushing and popping themselves take some CPU cycles
@RydwolfPrograms untagged unions don't allow you to have the same type as an option twice
and nullable types generally have no mechanism to use them as monads, which is generally quite useful
compare const x = a(), y = x === null ? null : b(x) with const y = a().flatMap(b)
I can't live without options (it's the first thing I add in larger TypeScript projects)
oh, another advantage of option types is that you can make an optional of an optional
when I say this people always go "I'll never need that" but a simple example is a function that does an HTTP request and returns an optional: if the request fails it returns Nothing and if it is successful but has no result it returns Just Nothing
of course in this case you might be better off with a result type, but still
Task is simple!
Take an array of binary values (can be boolean, 0/1, etc.) and use those bits to construct an n-th bit long unsigned integer
Examples:
[0, 1, 1, 0, 1, 0]
->
26
[true, true, false, true, false, false, true, true, false]
->
422
Functions are treated as the program
e.x.
function uint...
Create a function or program that takes any single-input function (f(x)=...) and returns an approximate integration from -1 to 1.
Functions will be treated as programs, with arguments as inputs and returns as outputs.
As always, smallest byte length wins.
EXAMPLES:
y=x^2: ~0.6667
y=e^x: ~2.3504
y...
@mousetail and if you're designing a type system from scratch to have nullables in it, it's just needless complication when you could have sugar for proper optionals instead--which is why you see it in these systems that are retrofitted onto dynamic languages to deal with dynamic idioms
it's still better than everything-is-nullable static langs but nulls are just icky period
@RydwolfPrograms hey if you take out a 30yr mortgage can I borrow about $3k so I can get another 4090 for my compute rig and pay you back $200 a month? Needs more power xD
@NewPosts Surely we've had a "convert binary to decimal" challenge before... right?
@RubenVerg I think f(x) = x*sin(1/x) is not defined at 0 and therefore not continuous, but if you assume f(0) = 0, f would be continuous and not differentiable at 0.
i thought of that too but it doesn't really answer the question; if you need to define it piecewise it's really easy to come up with a function with the criterion
I can't remember the title of this book. The girl comes home from boarding school because her paternal grandmother died. She invites her maternal grandmother who she was forbidden to talk to.
All of her family is some sort of supernatural. Her mom is half covered in jellyfish polyps, her grandpa ...
I hope my environmental science teacher doesn't actually read my review booklet...
I put "gay frogs" as the definition of endocrine disruptors, "unplug your electric chair when you're not using it" as a tip for reducing energy usage, and the boston tea party as America's main point source of water pollution
@user So, I still don't watch bad movies (at least not on purpose), but every time I see that one clip from The Last Airbender I burst out laughing... if you still like bad movies, maybe you'll like that.
I don't know about bad movies, but if you want to watch a movie series about farming and grain collection, I hear that the Rebel Moon series is pretty good
Sure it has some action sequences in it, but like for the most part it's good grain shots
How come github has a .gitignore template for some js web framework called Qooxdoo but not templates for more popular frameworks like React, Vue, or Svelte?
