Neat; simple but I like it. One concrete thing that jumps out at me as I play around with it: I keep instinctively trying to hit Ctrl+Z to undo, which doesn't work (and then I remember there's a button). Might be nice to make that

Yeah, I think there's a lot of potential in hybrid models like this. You actually do see these things out in the wild -- GUI builders come to mind -- but they're not a replacement for a proper programming language. As it turns out

Indeed, Amazon's behavior isn't the same shape as a typical monopolist. Krugman wrote an article a while back about this that I think cuts to the heart of the matter: https://www.nytimes.com/2014/10/20&#x

Yeah, this is kinda the cost of not having an encode/decode step. The Haskell implementation (of which I am the primary author) provides a higher-level API with "normal" data types for cases where performance requirements are

Skimming the implementation, there is buffering, but it looks like it's bounded, so tight looping Write() you should still end up blocking on the OS at some point.

Some of it is also that, much like in comparison to schema-less protocols, it's a bit of an apples-to-oranges comparision at the RPC level, since capnproto's RPC is so much more expressive -- but also complex to implement. I think

Thoughts on Sam? It seems to me like it might be a much better fit, esp. given the ed-like command only mode. (And I always liked it better than acme anyway...)

The signing schemes I've seen used in binary protocols fall into two categories: 1. Canonicalize and sign: the format has a defined canonical form. Convert to that before doing cryptographic operations. If the format is well designed a

The difference is that with coroutines, yielding is explicit. Tight-looping will hog the CPU, and a blocking call will block other coroutines too. Typically "green threads" are semantically just threads but cheaper. They're s

+1 for the bit about machine generated code. I think if you're going to have significant whitespace, Haskell does the right thing here: the indentation rules are specified in terms of automatic insertion of braces and semicolons. Almos

Are we even at the point where routers reliably support multicast?

The article actually advises setting fields to NOT NULL unless there's a specific reason to do otherwise. And re constraints: eh, for most applications this feels like premature optimization. My usual approach is to include whatever co

I struggled with this for a long time, I think a lot of us do. I don't know how broadly applicable my story is, but: at a certain point I basically cracked and picked a project and said "I'm going to finish this if it kills m

ADHD is absolutlely a real thing, it is treatable, and there is a large adult population that is undiagnosed. If you're struggling and you suspect it may be related to ADHD, you should look into getting tested. My girlfriend got her di

It seems like that's a concern with any testing strategy that mocks out some part of the system. Obviously there's no getting around actually testing against the hardware, but it seems like it could still be useful for the same re

I don't think we should be giving them tax breaks for investments that are only for themselves . They're going to do that anyway because it expands their business. If they were doing something that had a genuine public benefit,

The devil is in the details; a lot of the things they're getting tax breaks for don't benefit the public. Why are they getting tax breaks for building warehouses and data centers for themselves? Stock based compensation for execut

I'm not really interested in judging Amazon; they're a for profit company, they're going to do what's best for their bottom line. And I'm sure they don't care what I think. This is more about the systemic issue

I'd actually put modern crypto in the opposite bucket: there's virtually no physical constraints at all. You could do RSA by hand if you had to, and if nobody else has computers, you can pick a key size small enough for doing it

I stand corrected. I wish there was some nice off the shelf embed able FOSS DB like SQLite, but with datalog as a query language.

This is actually not true. Prolog is Turing complete, SQL is not. WITH RECURSIVE is limited to cases where you could basically use a simple foreach loop. The postgres manual has this to say: > Note: Strictly speaking, this process is ite

It still exists, and there are no plans to get rid of it. Same with other community infrastructure, e.g. demo.sandstorm.io has been moved off of oasis and still runs as well. It's only oasis that's shut down.
