Maybe I'll run into that, but like I just went digging into some packages to see if I could get myself lost, and instead I learned that Julia can work on raw pointers, and found a cool raytracer that seems pretty readable in the CSG pa

Being complicated and needing to care about the complications are different. For example, I use Julia as a fast, pseudo-Matlab desk calculator and haven't bothered to read about the type system [1] (I think I read a "so you'r

I'd like that too, but I think at this point, tactically, we need to come together on "we need some social programs, period", and not bicker so much about what that looks like on the first iteration -- there is always a secon

All of those jobs you mentioned are not economic, they are public works -- and there is no funding for them, so at best those are volunteer efforts, not something to put food on the table. You're right, in theory we could have a system

Comparing it against Rust doesn't really seem fair. If I wasn't using Haskell, I'd be writing Erlang, and last I checked GHC is much faster than Erlang/OTP. Certainly faster than CPython, Ruby, and most Node.js. Trying t

I can imagine a statement like: "We block all the annoying ads, and therefore there is no legitimate reason to use ad block, therefore we are forcing you to view ads because now they are all relevant".

You wouldn't write an Ada contract describing the full system, you would write one describing the local behavior you just described in your TLA+ model. The model ensures that the emergent behavior of the system is correct, and the loca

Huh? The whole point of distributed algorithms is that a set of local algorithms create a global behavior. I received this message so I send that message, etc. The SPARK contracts you write would check that local behavior, and the TLA+ woul

Drone ships sound interesting. The shipping company can definitely afford having a person remotely check in on millions of dollars of cargo every ~15 minutes or so, and so full autonomy seems like the 20 in 80/20 (maybe more like 95&#x

It's not that they don't exist, it's that current generation tech is not economical without subsidies [that don't exist], and therefore hasn't been scaled up. And there is no way in hell that a boat filled with batt

Citation? Most of the firms trying to make this work are growing algae in the desert (or the navy is just synthesizing jet fuel from sea water) -- and if companies are willing to pay for a literal boat load of Li-ion batteries, their cost&#

This is cool, but you can already have zero (net) emissions by running an existing container ship off of biodiesel or synthetic diesel. And the crews are so small relative to freight volumes that automating them won't drop costs very m

Capital One 360 pays 0.20/0.75 APY (checking/savings respectively) with no fees or minimums (I'm sure others do too, I just happen to be a customer ^). So... they are not benefiting. They are losing out on interest and a real

It's funny to complain about CORBA's local/remote muddling in 2017 when we have moved on to microservices that also talk to each other locally with TCP/IP.

I wrote it a few months ago. The resulting regex is linear time worst case in thompson or dfa regex engines.

The bulk of the article is about how the Go implementation avoids this behavior without just converting to regex.

Why write a glob engine at all when you already have a fast regex implementation that can match both exact paths and plausible subtrees? The bulk of the haskell code to do this: parseGlob :: Char -> Char -> String -> Parser G

If you magically increased the wind industry tomorrow by a factor of 31.2 to supply the entire US electricity demand of 4369TWh, you would have to employ 3.1 million people. That's only ~4 times the size of the US employment numbers fo

I'm confused how you got to this interpretation after I listed a bunch of cool languages that (I think) have made many improvements to CL based on CS research. There is only so far you can go with an "everything is mutable -- but

There is no reason to build a second Common Lisp. Those ideas are all fairly well represented, and you only need something new if you're diverging to different ideas: shen or haskell for types and values, julia for method dispatch, or

The whole point of capitalism is that you solve those problems from the bottom up, not from the top down. Pick one.

You can hot reload config files that you have already tested for correctness. No dropped connections.

The world we're in is one where the dominant use of pocket supercomputers is to send pictures, video, and messages around to our friends. Extrapolating to massive improvements in computing power per watt, and the main question is still

The advantage is having it built out of concrete. But because concrete has compression strength, not so much tensile strength, you need to store negative pressure not positive pressure.

I don't think a website has access to your autocomplete unless you select one of them.

I still think my initial reaction was reasonable, albeit subjective. But ya, we can stop debating semantics now.

You're right. Raising or lowering minimum wage purchasing power is worthy of caution, but having minimum wage track inflation is an economic no-op, not a shift in policy.
