I don't support this idea of rewriting everything in Rust but the answer to your question should be fairly obvious. Rust that compiles will generally be stable assuming you don't do a bunch of unwraps and panics. C that compiles can seem fine until it isn't.

LLMs still aren't as good at detecting C memory management issues as an experienced developer. With Rust, that doesn't matter as much because generally the compiler will tell the LLM when it's wrong.

This is all well and good in theory, but the number of times I've seen tests that don't actually test what they say they're testing is hard to count. Yes even when you encourage the developers to ensure the test fails first and do TDD. Tests help you ship with confidence but there's usually at least a few that are just passing by pure luck.

So no, I wouldn't judge a rewrite as being equal just because it passes the tests. That said, I don't think that means you shouldn't do it. You just have to be pragmatic about it.

Except all major social media sites are also corporations with their own interests. I'd rather the business model of traditional media that rides on journalistic reputation to a recommendation feed where the only job of it is to keep you on the site, especially when said feed can easily be manipulated.

No media organisation is perfect but your description of social media as some nirvana of decentralised truth is very questionable.

For what it's worth, this is commonplace in Australia too. I feel like you're describing a general safe country thing. I've lived in Japan so I know it's probably one of the safest places in the world, but I feel like what this thread describes is more US/Canada/some Euro countries being particularly dangerous, and not Japan being uniquely safe.

New comment by ShinTakuya in "Haskell Foundation 2026 Update"

ShinTakuya — Thu, 21 May 2026 09:18:52 +0000

I think the main reason more time might be spent thinking is because there's relatively less training data on Haskell out in the wild, meaning an agent may have to check back and forth with static analysis to figure out what's valid.

Compact syntax is generally only a good thing for LLMs because it saves context windows and tokens.

Plenty of valid reasons to pick C, memory safety isn't a reason to trade off all other possible benefits. One big reason is portability, you can't compile Rust for example for certain targets.

Do you need a reliable edge or just a slightly better than average edge?

I mean, supply chain attacks are a thing that could have happened even in the earlier days. Linux almost got backdoored in 2003.

Also with the number of remote code execution exploits that have occurred in Web browsers over the years it's hard to know for sure if what you installed hasn't been hijacked unless you spent all your time on gnu.org

ShinTakuya — Tue, 17 Mar 2026 01:08:19 +0000

No, there was a big internal project (which they communicated publicly about - search for the blogs relating to it) to address it that involved roughly a year of effort from a big chunk of the developers.

Rovo is backed by the typical LLM providers in general, Atlassian isn't training its own models.

If you're experiencing this you're either a very junior dev or you're not as senior as your title might suggest...

You're assuming performance has been the core priority, or even a priority at all, and I think this is a bad assumption to make. I would estimate a much smaller number of people-months of work if I were you.

Dev users assume the only problem a product can solve is performance, when there is a lot more than that in reality.

Or, you know, most steam deck users aren't using them constantly and so they don't get picked up in the survey.

The average Linux gamer is likely to have a very different setup to the average Linux user in general. It's a subset of a subset.

As far as I'm aware it keeps a history of the frequency you visit each directory so yes it will select the one you've visited more often (assuming you don't always start at the base one and work your way down).

New comment by ShinTakuya in "What to do with C++ modules?"

ShinTakuya — Mon, 01 Sep 2025 11:44:35 +0000

There's nothing inherent about C++ that makes it more suited than Rust for game engines though, Rust supports careful management of memory too. Of course, nothing besides inertia (i.e. Libs, existing code, etc.). And that of course is more than big enough of a reason to stick with it.

There are. The count is gotten by extrapolating from randomly selected areas of sky. This is more like another detailed picture of a small patch of sky.

I can't reply further to this thread without this devolving into a flame war so I'll just observe that you've moved the goal posts claiming you were just joking, and refuse to engage further until you acknowledge you're either getting defensive for no reason or arguing in bad faith.

While I agree they shouldn't be putting their money towards political causes, the scrutiny of the budget is also political in nature. Of the $400 million in expenses, only around $15 million went to executives, and around $1 million went to the DEI stuff. The rest was split evenly between developing and marketing Firefox, which is basically what you were criticising them on not doing.

If they got rid of all the executives and DEI, they could increase the other budgets by 2%. There is 0 chance that the 2% extra budget could help the market share and development in any significant way.

And if you don't pay executives enough, you get worse executives who make worse decisions because the good ones will go to other companies. So you'll be complaining even more if the $15 million executive pay got dropped.

So in short: I agree Mozilla shouldn't get involved in politics. Despite this, no reasonable person could look at the numbers and conclude it's having a material effect on the destiny of Firefox.

Is it that surprising that Edge is surpassing Firefox given Firefox doesn't have the onboarding ramp of Microsoft and Google? Microsoft shoves Edge in your face every chance it gets, as does Google. What can Mozilla do to compete against that? Unfair to use market share as an argument.
