addaon··on Git 3.0's upcoming SHA-256 default will be a costly mistake
> Adopt git 3.0 if you can with sha256.

Who is "you" in the context of a distributed version control system? I think this is not just the plural you, but the unbounded you -- it's all people who not just interact with your project now, but who you hope may interact with it in the future. The question is what the cost is of committing a near-infinite population to this migration, not the cost of doing a single `brew update` on your personal machine, no?

Pretty good baseball player.

His son was even better.

Wait, I guess this is someone else?

addaon··on Toyota is taking the Corolla electric
> I know precisely zero people who have EVs and do not charge them at home. The cost differential is enormous and completely changes the economics of cost per mile.

I know multiple people who have EVs and don't have a home charger, so do 90%+ of their charging at work. You're there 8+ hours a day anyway, and many workplaces provide free charging, so it ends up even cheaper than charging at home.

Except without the "getting the permit" part. A promise of a permit is not a permit. Try filing one at city hall and see how it goes.

> The only way to know if software does what is intended is to use it.

No, testing and code audits also work.

No amount of use of the software will tell you what else the software does beside what is intended (exfiltrate data, etc); testing and code audits both help with that.

> I suspect the intent is to move stale things out of RAM so it can be immediately used for more productive purposes when needed.

These are separate problems, though. You can clean a page by updating its backing store without purging it from memory; and purging a clean page doesn’t require a write. It’s definitely reasonable to take advantage of idle IO resources to clean dirty pages, but pages should only be purged (clean pages first, usually) when there’s an immediate need for them for something else.

That depends if the goal of handling your own traffic is integrity (which a VPN can give you) or availability (which requires dedicated pathing through a leased line).

addaon··on M5 Ultra Mac Studio Review: The Dream Mac for Local AI Agents
Ordered one for OpenFOAM. Excited for it. Will be nice to not have my laptop running CFD 24 hours a day, but my M1 Max is currently my fastest machine… I’m expecting about 3.5x from the M5 Ultra.
addaon··on Key symbols we lost to time, pt. 2: The Mac side
How would that work for all the software that distinguishes between them? The standard (see e.g. Mathematica) is for `return` to create a new line in a multi-line text field, and `enter` (`fn+return` on a keyboard without a dedicated key) to execute/evaluate/commit the field.

No, Mac laptops use LPDDR, currently LPDDR5X.

addaon··on Xcode 27.1 Beta Release Notes
Why? If you’re spending 2000 hours a year servicing your current customers, surely it’s worth 20 hours to add on 1%, even ignoring that that 1% is probably more valuable than your average customer, and the halo effect of giving a good experience to existing users migrating devices.
addaon··on Xcode 27.1 Beta Release Notes
> How many customers do you expect to be running on Duo for the first year of its existence? I’d be surprised if it was >0.01% for anyone.

How do you figure? Assume the average Apple cell phone replacement cycle is somewhere between 3 and 4 years. At the longer end, you’d need the sell-through rate of the Duo compared to other phones to be less than 0.04% to hit your number. We know from the Mini and other phones that Apple tends to avoid designs that it expects to have less than a 5% sell rate, two orders of magnitude higher. Even if you assume they’re aiming for 5% of dollars instead of units, and you take into account the non-Apple market (which certainly should not be unit-weighted for folks thinking about app revenue), you’re off by well over an order of magnitude.

> Selling somebody who owns a $4000 watch another watch is an uphill battle

I’d wager the future lifetime spending of someone who owns a $4000 watch on other watches is at least one and maybe two orders of magnitude greater than the general population.

If the code is written by an LLM, then it can't be copyrighted, and a license can't be applied.

addaon··on Most people prefer traditional architecture
"Traditional" isn't really defined here, but seems to mean "first half of the 20th century," which feels like a relatively narrow tradition. Not a lot of preference for teepees and yurts.

addaon··on Matt Mullenweg tells Automattic staff in Slack he's back in control after ouster
One challenge is that if everyone uses AI to build their own websites, the security vulnerabilities will be different per site, which is very inconvenient if you want to compromise a huge number of sites simultaneously. It's possible that AI tools for exploiting websites scale to overcome this challenge, but it's going to be hard for AI to compete with Wordpress for security vulnerability density, uniformity, and cost.
addaon··on I have a theory that software drives people insane
> when the whole benefit of computers as a tool is that the UI is infinitely flexible

I think this statement is insane. The benefit of computers is that they allow complex behaviors to be defined and implemented. The benefit of software is that it’s the lowest-NRE way of defining those complex behaviors. UI doesn’t come into it, except in a few edge cases like desktop computers, phones, appliances, etc. A climate model’s “benefit” comes from its output, not the form in which it generates output or takes input.

addaon··on I have a theory that software drives people insane
> It's why only software like text editors and web browsers gets to be really good. Huge user base. Lots of developers involved.

There's lots of great software out there that you interact with every day that was written by a small number of developers to clear requirements. Your car ABS brakes. Your coffee maker. Your brushless drill. Your TV remote. Think of the fact that majority of the microprocessors and microcontrollers that you interact with every day have software that you never think about, because it just works and gets out of the way. (And think of the cases -- maybe your dishwasher, your smoke detector, whatever -- where that's not the case! It really drives home how incredibly pleasant just-works-without-thought really is.) It's only these big, large team, overly complex systems where the expectations are so low that even the crap that is a current web browser is considered acceptable, let along "not sucking."
