Aside from the "assertion" libraries, which I have mixed feelings about, I often use table-driven tests to avoid this. That way each test is generally one line, like `{"1234", 1234}` for testing an Atoi function. Or, I&#

I suspect in part it's a combination of 1) Go is good enough as is (and some people don't mind Go's simple type system or the boilerplate-y but explicit error handling), and 2) the Go tooling is really good -- "go build&

For better or worse, this is by design. See: https://golang.org/doc/faq#methods_on_basics It's "to avoid complicating questions about the interface (in the Go type sense) of basic types". It also allows

Note that this switches to a register-based calling convention, but it's not the platform "standard" one. The Go authors describe the rationale for this here: https://go.googlesource.com/proposal/+&#x2F

Overall for GoAWK I get an 18% speed increase on my micro-benchmarks between Go 1.16 and 1.17 (see https://github.com/benhoyt/goawk/commit/1f314f421273b3dc164f... ) and I measured an 8% speed increase on my &q

With the introduction of generics in Go 1.18 and the accompanying "slices" package ( https://github.com/golang/go/issues/45955 ), we might soon write that as: a = slices.Delete(a, i, i+1) That

Wow, this update is awesome: my GoAWK interpreter ( https://github.com/benhoyt/goawk ) runs a simple CPU-bound AWK program 38% faster when compiled with Go 1.17 (compared to 1.16). $ time goawk_go1.16 'BEGIN { f

To me, the most interesting change is the performance improvement due to the new register-based calling convention. Your CPU-bound programs will magically get 5% faster when compiled with 1.17: > Go 1.17 implements a new way of passing f

We have a 14-year old daughter who's been begging us to get her a phone for a couple of years now (we've said she can at 15), and I'm guessing she doesn't experience that much social ostracism, but she does experience

My own experience backs this up: on the hiring side, I always use someone's personal projects as a fun discussion point in interviews (if they don't have any it doesn't count against them ... but like simonw says, it may help

New Zealand is proposing a similar law change: https://consultations.justice.govt.nz/policy/incitement-of-h... ... it's ostensibly in response to the Christchurch mosque shooting of 2019, but I'm very wary of

Yeah, this is rather strange. I mean, it's vaguely interesting, but contains so little information and so few details it really doesn't seem front-page worthy, let alone worthy of the #1 spot. I thought about flagging it, but it&#

Excellent article -- despite (like others) disagreeing with several of his specific points, I think his overall take to optimize for predictability, readability, and simplicity is great. A few years ago I took over as tech lead at a previou

Yeah, I like the "visual boundaries" way of framing it. A line of whitespace is a visual boundary, of course, but I find the // comment above it acts as a heading. Like a bold heading above a couple of paragraphs of text

I have no idea what Triplebyte gets or even what their business model is, but typical recruitment companies get a lot more than that -- on the order of 15-20% of the first year's salary, so on the order of $15-25k. I suspect Tripleby

I think this is inspirational but it seems like puffy popular science ("pseudo-science" may or may not be too strong?). I'll quote what I wrote to a friend about this article: > It was intriguing and piqued my interest. Ho

Thanks, that's a great idea -- not sure why I didn't think of that, as I am using the assembler to figure this out for if/else forward branches already (as the parent comment pointed out). I've added a paragraph to the a

Wow, I had no idea the Oberon implementation was so small, thanks. And it looks like it's implemented in a similar way, with parsing and code generation mingled together. It is ~2900 lines of code, though it's very dense. You can

Interesting. I couldn't find any documentation for how this happens (does it need compiler/linker support to know whether free is used?), but I did find the source code for this __simple_malloc: https://git.musl-libc.or

Wow, that is impressive, thanks. I confirmed this with godbolt.org at -O2.

by benhoyt 6y ago
Yes, that's correct. I actually initially implemented local "var" parsing, but was never using it in the compiler, so I removed it to trim it down and keep things as simple as reasonably possible.

> can and probably are optimizing the loop away Why do you think that, and how would it do that and still do the calculation? My timing tests showed that Go didn't optimize the loop away (if I counted to 10 billion it took about 10
