Yes, definitely. The first three chapters would be more than enough for that: 1) An Awk Tutorial, 2) Awk in Action, and 3) Exploratory Data Analysis. For most people who just want to use AWK for one-liners on the command line, you can stop

I was privileged to be one of the technical reviewers for this book. There's a fair bit of the original content (which is still great), but Kernighan's done a great job with some good restructuring and some significant updates, to

No, unfortunately the Gawk/awk --csv option doesn't support writing back to CSV. FWIW, GoAWK supports CSV input mode with "-i csv" and CSV output mode with "-o csv" for this purpose, as well as special syntax f

> avoid quotes when generating them Yeah, I guess that kinda works if you're the one generating them. But you must not have too many generalised strings -- like a name field containing "Smith, John" or a book title like

Unfortunately "awk -F," (field separator of comma) doesn't work with most real CSV files, because of quoted fields, commas in fields, and (less frequently) multiline fields. My GoAWK implementation has a CSV mode activated wi

It is a big release, and the number of new stdlib packages (4) is relatively high for a Go release. That said, apart from the addition of some minor builtins (min, max, clear), the language isn't changing. That happened back in 1.18

It looks like sync/errgroup is a proposal, but not in the standard library (not yet, at any rate): https://github.com/golang/go/issues/57534

I like (most of) this list! Note, however, that most of these are more for writing Python code, whereas my article was specifically about designing Python APIs -- that is, the public-facing stuff. A few specific comments on your points: &gt

Thanks for sharing! I do like the OP's article, but the more the merrier! My "How to implement a hash table in C" article [1] is for whatever reason one of my most popular articles. If only C had a slightly better standard li

Indeed! I just saw this in a submission I was reviewing now. AI writing is well-structured but extremely boring and generic.

I've been reviewing answers to questionnaires we send out to potential software engineering candidates. Sometimes candidates seem to write 90% of the submission themselves, and then use ChatGPT for the last couple of questions (which a

Definitely a good change, as this fixes an issue I (and I think most Go developers) have been bitten by more than once. It was really interesting to read the response of someone from the C# team in the original discussion, of how C# had gon

Good to know, thanks. Out of interest, why do you dislike Go's design philosophy? I can guess, but I'm interested to hear your take.

I upvoted because this is interesting and I like simple compilers, but unless I'm missing something, this is only a lexer and parser. They mention "rgo was to use LLVM" in the README, and there's no type checker or compi

It is definitely neat, but I think it's more than an exercise. I believe he runs it through the extensive SQLite test suite (I've seen that before, though I can't see where that's stated now).

No: definitely not imminent, and probably never. Originally "Go 2" was the name for a real version 2.0 where the Go team would make breaking changes and fix any warts. However, over time they decided a big breaking release wouldn&

Are you allowed to say what project/product it is? I'm curious. Do you use type annotations? I've found refactoring sooo much easier in statically typed languages like Go than in Python, even for medium sized projects.

Yeah, I did the exact same thing and got very similar results. Just to save people clicking through, the Go/goroutine version is 25x as fast as Python. :-)

I just checked one of the best "online-first" technical books I can think of, "Crafting Interpreters" by Bob Nystrom, because it uses side notes heavily. What it does when the screen width is narrow (like on a phone) is

Yeah, this is a good point. I've previously just used the "hash in the URL" approach as it seemed more obvious than ETag. I asked Ben Johnson why his hashfs library uses both, and he said "Yeah, that's a good point.

Heh, that's funny. I distinctly remember typing it in from scratch just the other day (no Copilot), and I guess it's short enough it sorta writes itself: the function name is kind of obvious, the name of "defaultValue" i

Sorry if that wasn't clear. This was meant to answer it: > Fly.io looked more geeky and command line-oriented, which suited me, and their prices are also ridiculously low: free for up to three small virtual machines (I only need two
