Why doesn't set -e (or set -o errexit, or trap ERR) do what I expected?(mywiki.wooledge.org)

What do you mean by crappy? I've always found it very lovely and welcoming (though a touch small). The Julia community is also (in my experience) skewed towards scientific computing rather than software engineers which can definitely h

Stefan Karpinski (one of the core Julia contributors) gave a talk (in 2016, so rather dated as far as the Julia syntax and whatnot go) about how Julia is secretly more lisp-y than even lisp & Scheme. The core of this argument is that mo

I don't have any real issues with Go. Setting up GoLand requires manually choosing the Go installation to use (at `~/.asdf/installs/golang/1.19`) and manually changing it when I upgrade the project, but since the ve

The images shown at the top are (probably) designed to show off the full "dynamic range" of the color palette, but reading those code snippets is a bit overwhelming (and I suspect it's just because you've crammed so many

Seconding this. It’s easy to be overwhelmed by the seeming combinatorial complexity of things. Just start a little personal wiki (eg, arrow syntax, structural typing, etc) and it’ll help you decompose things into more easily understandable

Other than rm -rf / (which can happen if you manage to hit enter rather than another key) this feels not terribly useful. Who has accidentally kubectl delete ns prod? Anecdotally, the accidental enter seems like a much more likely scen

Super neat! Admittedly I haven't played around with it too much, but I recently attended a keynote by the love Felienne Hermans that was all about her Hedy ( https://www.hedycode.com/ ) "gradual" programming la

Worth noting that some of these can be detected statically -- and some are detected by go vet (e.g., passing a sync.Mutex by value). I don't think it detects the wg.Add bug, but that seems relatively straightforward(†) to add a check f

This is also what Yugabyte (OSS) does, at least according to my general understanding. It also supports the Cassandra API (though not to access the same data).

As a Seattleite who uses a bicycle as the primary means of transportation (but not a bike enthusiast or “bike person”): these are nice (experienced them a bit in Ann Arbor) but the only way to truly make biking safe is going to be to remove

At some point, you can't gracefully handle bugs in other peoples code. If a function you call causes a SEGFAULT, in the vast majority of software, you're not expected to handle that. That's an invariant error, and you probabl

There are products that do that! Hasura comes to mind. But APIs can have different use cases. It’s usually considered bad to directly expose your table schema over GraphQL because it locks you in and makes it hard to change your data model

I’ve found it easiest to implement in Node due to the explicit event loop structure. You use data loaders, which is a super generic term that means “batch all requests for this resource into the next event loop tick.” So when a query reques

Facebook has a terrible track record when it comes to open-sourcing their internal tools. See: Phabricator, HHVM, Flow, Jest, ... Even React, which is their most popular library, is not actually "open source." They're very tr

i’m also not a db engineer, but i think this is true-ish. however building and maintaining those index tables is hard and probably prone to issues if you can’t update multiple as part of the same transaction. the other major thing you’d mis

Interestingly, I suspect Facebook employs the largest auto-loaded codebase in the world and I suspect this is made easier by the fact that everything is controlled under one roof. There is some namespacing (à la PHP namespaces) for standard

I learned Dvorak because I knew I would never work out the bad habits I had with QWERTY. Dvorak is a HORRIBLE layout for mobile, but I used it for about a month while learning Dvorak and it really helped. It’s horrible since you often type

In my experience this isn’t idiomatic Go and would definitely turn heads in a code review. But in such a small function, it’s fine to just not worry about the lifetime of your variables (and in bigger functions you can often decompose into

This is definitely not the case. This publication has multiple posts about the supply chain and port affairs. Software/tech people sometimes forget that we live in a very specific world with very limited scope, and sometimes forget to

Yep, and beyond that, there's still a need to remove cars from the world, both to fight climate change and to make cities livable again (see any video from the "Not Just Bikes" YouTube channel for support for this argument).

I think here “rewrite” means completely changing the internal structure of the code (while preserving the functionality) whereas “port” means copy the structure of the internal code with as little modification as possible. And it’s hard to

I haven’t personally benchmarked it, but I know it’s available as an eslint rule (all exported functions must have declared return types).

To this point, many teams are already using subsets of TypeScript to improve compilation times. Often times it’s things like always declaring return types on functions to avoid the compiler having to infer it (especially between module boun

My impression of the article is just that the author is a fan of green threads (goroutines). Green threads don’t really make sense without an integration into some kind of IO runtime, so calling out how Go does do this seems moot. Other l
