Oh yes certainly. And I think that when you're deep into creation it can be really really hard to remember that experience, and so recently I'm trying to find ways to help pull back the curtain for folks.

Well some of us do. There's this interesting effect where many people perceive the limitations on their current tools to be equivalent to limitations on their abstract abilities. If they don't know how to do it, it's imposs

Editors generally support composing right-to-left languages that way? So I suppose the metaphor suggests that all editors should directly support the visible glyphs semantically? And yet, that's explicitly not the semantic purpose of

I'm not sure we have full data on the question, but by my own experiences the default expectation for most people regarding version control is copy the file and rename it. The default expectation for most people on collaboration tooli

To some extent there's a horses for courses argument here: which projects stand to benefit from a high proportion of drive-by contributions? Which projects can appropriately leverage nuanced textual discussion? If the Linux kernel had

You describe a very real problem, but from what I can tell it's an entirely disjoint context. I'm honestly not clear what the scenario you're suggesting is. Your platform would send an authenticated URL to a verified user o

Where in that article does it say that the self, that human consciousness, that a soul arises purely from the arrangement of particles in our bodies?

If anybody but the intended recipient gets the magic URL first there's something more critical wrong with some assumption in your authentication scheme.
73.
by couchand 3y ago
Indeed, the only valid operation with the magic URL is exchanging the URL-based token with something else (your PDF, a session token, etc.) and then expiring the URL, so by the time the scanner gets around to it the original URL is invalid.

Congrats on the show HN! It looks like you've put a lot of thought and effort into this, and reasearched a number of alternatives. I'm curious to know more of what you found lacking in the various visual programming languages? Y

The model seems quite similar to a subset PD, with only object and message boxes. Objects can have only a single output port. (edit: I was mistaken, they can have multiple ports, though as far as I can tell there's no port-sequencing

Woah woah woah let's not get hasty. We can have panicking and nonpanicking versions of the API (at least until somebody builds the nonpanicking version of Rust, that will be great). The panicking version is for quick, off-the-cuff us

Regardless of how supposedly non-controversial each technical design decision is, you will find that the entire scope of them never is. So you will always be working to bring people along to your design choices and help them understand the

Every word you wrote is true. It's all still true if you replace "DSL" with any project and "Boring Old Language" with the competitor. This is the stopping at 90% problem somebody just posted a link to in another t

by couchand 3y ago
The point I (and it seems several others here) are trying to make is that your API already is a DSL, the question is just whether it's a good one or a bad one. A good one is internally consistent so that users have predictability when

Panic is perfectly fine in certain cases, but it's absolutely not a general error-handling mechanism for Good Programs (TM). (Some contexts excluded, horses for courses and all that) You can and should recover from bog standard IO fail

Very good point. See, for instance Kiselyov's embedding of his tagless final form: https://www.okmij.org/ftp/tagless-final/course/lecture.pdf

Yes, eat your vegetables! A question of philosophy: If you have all that, don't you already have a DSL, using a deep embedding in the host language?

> mallocing every object So don't do that then? Put most things on the stack. It's far faster than any allocation.

I think most people's concern with GC is not the allocation side of it? And in any case alloca blows them all out of the water. > if latency matters you end up having to care about (de)allocation patterns at the app level. Yes, and

I suspect they're heavily relying on intuition coming from Rust, where both of those forms are okay. The one from TFA is sugar for your version. This works fine as long as there is only a single await point, otherwise you have to tra

I suspect the GP was merely suggesting a less-costly alternative. Perhaps building a complete standalone compiler or interpreter is hard, but we're all designing APIs in our programming languange of choice day in and day out. Both str

Don't be so quick to discount DSLs. Sure, you don't want a half-baked DSL when some simple imperative code would do. But if you watch your API evolve into an algebra and then don't formalize it with a DSL you might be leavi
