A perfect linter runs into the halting problem, I think, but a pretty-darned-good linter that would catch that methods on your pointer-based method doesn't do "something sensible" with nil would be pretty interesting to me. I

Syntax highlighting fixed that for me something like 20 years ago. But then, like I said, I consider extensive use of this a code smell at best . If you're doing this often enough that this is an actual problem for you, then you'

Maybe someone else somewhere is getting some unbelievably sweet deal but what I've seen from cloud discounting is more in the "single digit percentage" range than "2/3rds off" or something.

"Am I out of date and we just call that string interpolation these days?" It's all just spelling. Your compiler just turns x = "I want ${number/12|round} dozen eggs, ${name|namecase}" into x = St

Because in the last dozen times I've handled this question the root cause is lack of understanding of why. Inductively it is logical to conclude that's the reason next time. It is probably also the case the bulk of readers of this

No, I'm not forgetting fictional cases in which the point was to transmit to an unknown civilization. I'm talking about the real way that real civilizations are going to transmit data to each other, without meaning for it to be pi

It's not that the ship has sailed, it is that if you sit down and sketch out what people think they want it is logically incoherent. What Go does is the logically-coherent result of the way interfaces work and the fact that "nil&q

It kind of is. You're thinking directionality, but there's also the fact that optimal transmission will involve using compression and possibly encryption, which by its nature turns the signal into noise if you don't already k

If you think about it, what would it even mean for an AI to give an "unbiased" answer to "How should I vote in $ELECTION?" It's a staggeringly huge pile of numbers and the idea that it would somehow be precisely bal

Tron is a fantastically difficult franchise to write for. It is, in my opinion, the most alien franchise in Hollywood. It's unusual for alien worlds in Hollywood to have different physics , but the grid does. Its residents are not h

Textual language is really, really amazing if you sit down and think about what it does versus the resources it consumes to do it. It's a common pasttime for programmers to claim that our textual programming languages are just terrible

My comment about how "cargo culting" is not an appropriate metaphor "falls apart" because you named another way in which the metaphor is not appropriate? This is some bold new definition of "falls apart" with

Cargo cult as a metaphor doesn't work here. That's for when the cargo culters don't understand what is going on, and attempt to imitate the actions without understanding or accuracy. AI investors understand what is going on a

I didn't try to hit that because that's harder to call, especially at a small startup. If what is probably "the guy doing all this" happens to be more comfortable with k8s than the AWS stack you can end up winning by goi

Saving $400/month covers about 3-5 hours of engineering time per month. In a year, call it 30-50 hours. Did this project take more than 30-50 person-hours? (The obvious argument about how it might pay off more in the future are depende

I can't be an expert in every GC implementation because there are so many of them, but many of the problems they mention are problems in those languages too. Finalizers are highly desirable to both the authors of the runtimes and the u

This sort of thing is definitely in the class of "are you experiencing problems? if not don't worry about it". If you are experiencing problems, this might give you an angle to think about that you hadn't otherwise, if y

If the author has not already, I would commend to them a search of the literature (or the relevant blog summaries) for the term "implicit parallelism". This was an academic topic from a few years back (my brain does not do this so

V8 gets C++-like performance when it is getting code that JITs very well. This is typically highly-numeric code, even sometimes tuned specifically for the JIT. This tends to cause a great deal of confusion when people see the benchmarks for

If the Go compiler was twice as fast, I wouldn't really notice. If the Go linker was twice as fast, that would be a minor convenience, sometimes. I wouldn't expect much more that twice, maybe thrice at the very outside. And it&#x2

Are you thinking of some sort of annotation the compiler could read and handle? Because if a compiler starts automatically padding all my structures to put all of the members on their own cache line I'm going to be quite peeved. It wou
