Even more confusing. Do we know which data is in which keychain?

Disturbing if true, as it suggests my "everything" backups aren't really full backups at all. I wonder, if you have enabled iCloud keychain, does that provide another way to get your passwords back? Suppose my MacBook is stol

Another way (which happens to be correct) to say tenth of a second is 100 000 000 (one hundred million) nanoseconds. You were off by a factor of 1000!

There's a meta-level of irony here that's important to note. TFA is defending the use of AI, and it very clearly (to me) used AI to analyze the data and present the results. In doing so, the author used statistics in a way they do

You say "the underpowered study did not find evidence". Not true, it found quite a bit of evidence - many statistics were presented. There is no absence of evidence. The author wrote about the evidence, presenting P values and

Perhaps in an “everyday language” way, but not in the technical, statistical sense. In an underpowered statistical study, a claim that two experimental conditions did not differ are not persuasive.

The concept you need here is "Statistical Power". The ELI5 version is that there are two mistakes you can make when looking at a P value: Type I error, where your P value is falsely low. In the experiment being discussed here, it

Ollama users: there are notable bugs with ollama and Qwen3.5 so don't let your first impression be the last. Theory is that some of the model parameters aren't set properly and this encourages endless looping behavior when run und

> Sheldon Brown, a beloved iconoclast bicycle tech guru, died Sunday from a heart attack. He was 68 63. Curious, what does "He was 68 63" mean. Is it a bicycle gear joke about his age at death?

On Mac Safari, holding shift and using the magic mouse to scroll up or down reverses the zoom direction. This is both right (Shift-X is the reverse of X due to convention) But is also wrong (Shift-Scroll is the macOS gesture for scrolling

Right, this annoyed me too - it was stated w/o attribution as if novel. What is the name of the law when someone writes a think piece of "stuff I've learned" and fails to cite any of it to existing knowledge? Makes me wo

You mean 1990. Someone graduating college in 1990 would have been about 21. That was 35 years ago, so they would be about 56 in 2025. Math is hard.

The CFR is pretty clear, and I have experience with this (being both an IRB reviewer, faculty member, and researcher). When it says "is exempt" it means "is exempt". Imagine otherwise: a teacher who wants change their f

I really hope the user was running Time Machine - in default settings, Time Machine does hourly snapshot backups of your whole Mac. Restoring is super easy.

Why not do an empirical A/B test: Set up two honeypots (or perhaps 2000 for statistical significance). A gets zero updates, B gets all updates immediately. See which ones get pwned faster.

I am baffled by Apple's incompetence here. In the past years I've seen: * iTunes/Music app randomly reassign my Album artwork, with different (incorrect) art showing up on different devices! * Reminders app: shared reminder

Good points this wasn't entirely a protobuf-specific issue, so much as it was a (likely hierarchical and historical set of) bad decisions to use it at all. Using Protobuffers for a few KB of metadata, when the photo library otherwise i

I share the author's sentiment. I hate these things. True story: trying to reverse engineer macOS Photos.app sqlite database format to extract human-readable location data from an image. I eventually figured it out, but it was: A base
