In a correct program, the borrow checker has no effect. Languages like C compile code with the understanding that if the compiler can't prove the code is incorrect, it'll assume it's correct. Rust compiles with the expectati

Unsafe isn't so unsafe that it disables the borrow checker! The two main things the compiler allows in an unsafe block but not elsewhere are calling other code marked "unsafe" and dereferencing raw pointers. The net result i

Cloudflare needs to worry about their sandbox, because they are running your code and you might be malicious. You have less reason to worry: if you want to do something malicious to the box your worker code is running on, you already have

Honestly, for my own stuff I only need one PoP to be close to my users. And I've avoided using Cloudflare because they're too far away. More seriously, I think there's a distinction between "edge-style" and actua

I would probably be Software Engineering even if my employer didn't pay me to. As evidence, note that it's new year's eve and I'm writing patches (and waiting for tests) during my holidays for someone else's FOSS p

That makes things worse if all-zero is not a valid value for the datatype. I'd much prefer a set-up that requires you to initialise explicitly. Rust, for example, has a `Default` trait that you can implement if there is a sensible

I think you might appreciate https://www.jj-vcs.dev , which makes it a lot easier to split and recombine changes. I often use it for checkpoints, although you wouldn't see that from looking at what I push :). One nifty fe

Strong disagree: until the branch is merged, it's mine . I'm in a camp that prefers single rebased commits as units of change, "stacked diffs" style. GitHub in particular was annoying with this style but is definitely g

Not everyone in my team wires up their pre-commit hook to run the pre-commit tool. I use JJ, so I don't even have a pre-commit hook to wire up. But the tool is useful. The key thing (that several folk have pointed out) is that CI

I think you might like https://www.jj-vcs.dev/ — it snapshots before every operation, and can watch the filesystem to snapshot every change.

That's a controversy I'm not sure you necessarily realise you've stepped into :). It's fairly common to consider working and PR branches to be "unpublished" from a mutability point of view: if I base my work on

You shouldn't be relying on hooks to maintain the integrity of your codebase, and I'm not seeing anything here that makes me want to avoid `pre-commit` (or, more literally, the https://pre-commit.com/ tool). CI

I keep a couple of jj aliases that apply the `pre-commit` tool to a commit or a tree of commits: https://github.com/andrewaylett/dotfiles/blob/7a79cf166d1e7b... What I really want is some way within jj to k

I feel like folk in this thread haven't used a Macbook Pro from the past ten years or so — which is fine , I don't expect everyone to want to use MacOS (I prefer Linux) but the hardware is genuinely nice. On my personal 2019 MBP

It is, however, literally worth that amount of cash at the moment of redemption. If you were going to spend that money in that shop anyway, and you have no intent to sell the card to a third party, there's no need to apply a discount.

On the other hand, it's trivially true that the store which "issues" (caveat explained in the article, they don't actually issue anything themselves) a gift card will accept it as a valid form of payment.

by andrewaylett 10mo ago
It's interesting (to me, at least) to see the kinds of discounts that folk apply to gift card transactions. It's not unheard of for a colleague to end up with a gift card they can't use, and while there's a real sense i

One thing I didn't think Patrick quite explored enough: there's a big difference between someone asking you to pay using a gift card and you asking to pay using a gift card. The examples he gives are predominantly around givin

In my experience, levels are more a question of delivery and trust than of technical skill. If a Senior is off down a rabbit hole, that's them doing their job. It's almost a defining feature of the level down (SE2, or local equi

No, it let you continue to follow the main branch for most files, while files you edited would have their changes saved to a different location. And was just about as horrible as you might imagine. We moved from VSS to SVN, and it took a

I definitely get the impression that Wolfram builds his tools primarily for himself, and is happy to let other people play with them because that way he gets money to pay for them.

While I almost certainly wouldn't have done more than wished for one, it's a shame they're not getting any return for their effort.

BMW have one of the more annoying matrix main beam setups, as far as I'm concerned -- it's not great at picking out my car, and seems worse than others I've encountered. A redeeming feature is that it does seem to be smart
