I would argue that one of Go's strengths is its resistance to bad code. Sure, you can still write gross Go. But I'll take gross Go over gross C++, gross Haskell, or gross Python any day.

Given the provenance (MSCHF), I guess we can safely assume that the..."unfortunate"...MschfBoard logo was fully intentional.

The type system can't catch nil dereferences or out-of-bounds accesses, which (in my experience) are the most common causes of runtime panics in Go. I assure you, there are many ways to make a Go program crash. :) If your program is

Only thing keeping me from switching to this is the ability to jump from docs -> source code. It looks like they do support this in some form, but not in a way that's backwards-compatible with existing packages, which is kind of a d

Good example of this: What is the complexity of the fastest algorithm that prints the nth Fibonacci number? Novice: "O(n), because you have to iterate from 0..n." Expert: "O(log n), because we can use matrix exponentiation.&q

Yes, personally I would not recommend this approach, just wanted to clarify how such a thing could be achieved.

You can release a hardfork, such that all participants agree to treat the offending block as a special case. No different from the Ethereum DAO fiasco.

I think analyzing languages through the lens of incentives ("what is this language pushing me towards/away from?") is a great idea. But if Haskell's incentives make it well-suited for programming in the large, why is it

Not really; both the private key (scalar) and public key (point) are encoded as 32 bytes. However, some implementations concatenate the two and refer to that 64-byte array as the "private key" -- this is simply an optimization so

by nemo1618 5y ago
The process for generating a pubkey is: 1. Hash the private key 2. "Clamp" the result 3. Multiply by the base point Clearly step 1 will give you an equal chance of any 5-byte prefix, so the question is whether ste

meh, I found Girl who Leapt through Time, Summer Wars, and Your Name to be pretty forgettable. Spirited Away, Tokyo Godfathers, and Akira are obviously classics, but none of them have made quite as deep an impression on me as EoE. I guess i

by nemo1618 5y ago
Call me crazy but imo it's worth watching the entire series just so that you can then properly enjoy EoE -- which is surely one of the greatest animated films ever made.

I would argue that it is: it's explicitly a language designed "in the service of software engineering," which is something we're still figuring out how to do. It has implemented novel features that serve this end, and le

For me, it's not a question of terseness -- it's more about communicating intent, and not polluting the scope with incidental variables. Everyone knows what map/filter/reduce do. When reading new code, seeing "map&q

What I really missed was generic map-function-over-slice, which could be handled by adding a much narrower feature. If one graded possible Go point extensions by a figure of merit in which the numerator is "how much

Good luck! I recommend building up a library of helper functions; it will save you a lot of typing. Here's mine: https://github.com/lukechampine/advent/blob/master/utils/uti...

One nice thing about lightweight crypto is that it's easy to port. Implementing ASCON in Go was pretty fun and only took an hour or two: https://github.com/lukechampine/ascon/blob/master/ascon.go (O

Surprised to see no mention of Urbit, which sits somewhere between Uxn and Linux. Holding Urbit's OS in your head would certainly be more challenging than Uxn, but it's still doable. When something breaks, you can actually fix it
