Yeah. The probabilistic access patterns for games are going to be comically repeatables for prefetching.

I used additive gaussian fields (restricted by bounding regions) for this back in the late 90's for audio visualizations in a ripper/player called "Siren" (back when we actually thought we could charge money for somethin

That sounds more like a bizarre brag than anything else, a "we would have invented it if you hadn't" statement. There's value in being unencumbered by the directions of others, but there's an even larger value in be

The cost of having a thorough inventory of apps that being in monetization is vending apps that have none. It's part and parcel of keeping users inside the walled garden. Google takes a hit on some apps to sell and advertise with othe

Behavior change hidden behind targetSdkVersion is a bear trap that keeps on providing trauma. It’s just a massively dangerous way to evolve API’s. That said, automated regression testing, target environment deployment tests, and beta applic

As a user, I’d rather that Google make stable and coherent APIs the priority. If the strategy is: 1. Make breaking API changes, but gate them behind the targetSdkVersion. 2. Force app devs to lift the targetSdkVersion to stay up to date by

No. In the set of integers, 1 is not two divisors if repeated. It is one divisor. An element to set relationship is that element A is or is not in set B. So, if the set of divisors only contains 1, there is only one divisor. If 1 and 1 mad

Well, I’m questioning it… not that it really matters. -1, 0, and 1 are no good. Two divisors for positive integer X: 1, X I recently demonstrated GPT-4 via by having it explain phases of matter metaphorically with animals. Though impressiv

Are we including it just to poke the bear? Prime numbers are typically defined as numbers with no positive divisors other than one and the number in question.

To me, this is the core bait and switch problem. It’s not just that expectations and commitments are suddenly unilaterally changed. Is that the core subject of the license (an open-source codebase) has quite often been built collaborativel

Note: SIMD on x86 has unaligned instructions that used to be much slower (decoded differently) than their aligned counterparts. For example, on Pentium 3 and Pentium Core 2, the unaligned instructions took twice as many cycles to execute.

That’s why, while much of the linked blog is kind of off the mark (signs of someone knowing less than they think they know), the general conclusion, using aligned pointers is recommended, is one that I typically recommend to developers new

An unlicensed driver in the Mission plowed into me on my motorcycle because he panicked and slammed on the gas. Cruise cars, conversely, generally result in close calls due to aborted lane changes, cutting me off, or absurd double parking,

Whether it’s shift, mask, multiply, Kernighan’s method, or something else, it’s going to be multiple instructions and tens or hundreds of cycles to do this in software. pop count instructions take a handful of cycles to run (~10 on ARM, ~3

That’s classic cost benefit analysis, and there are plenty of examples in audio of trade offs where the simulation is sufficient (or more flexibly applicable). Just because the cost is high for a given application doesn’t mean something ha

Why do you think time dilation needs to occur in our simulation? Be it from instance-shard transition due to cell crossing (special relativity) or inter-node lag due to spatial density (general relativity), system design constraints dictat

Thanks for inviting questions. This is a very fun idea that basically turns the Spruce Goose’s single flight in ground effect into a scaled reality. Amazing. With what is likely 1500+ pounds of battery, what is the operational charging&#x

Is ISS between satellites that are expected to de-orbit and the Earth, or is it not? I'm well aware of tracking and avoidance mechanisms, but, up until now, I hadn't considered the orbital planes in use.

The point isn't that I should be worried. The point is that folks in ISS should be more worried than if they were, say, at 600km...

I'm talking about them hitting ISS.

I'll put $10 up against that bet. In a few billion years, one of us is going to look pretty stupid!

The moon is slowly getting farther away. Starlink satellites are expected to relatively quickly return to earth.

by chaboud 3y ago
Huh. I wasn’t worried before reading this thread. Now I’m a little more worried. 1. We don’t need to worry about Kessler syndrome, as the orbits of Starlink will decay in five years (from 550km). 2. ISS is at 420km. Has anyone else ever w

Sort of, but without the duplication and initial wait to load. A traditional fat in-memory app would do this: file (DISK) to process active pages (RAM) to paged out virtual memory if saturated (elsewhere on DISK) Using mmap typically goe

That's down to caching. If you used your system to do something else for a while, you'd find those pages evicted and the performance back down to Earth. That's one of the things that makes mmap so useful, though. The system
