For like a decade, the "opt-in" to ACR was included in the ToS agreement needed to use any smart features. Then at least some brands made the opt-in separate, but made it look like a recommendation engine or "help us improve

The C1-ultra has a decode of 10 instructions but can issue up to 23 uop per cycle, that’s a good bit wider than any other CPU. In particular, I believe it’s the first CPU to have a 4th load pipeline.

All 10 cores support the same extensions. It’s silly to implement an SoC any other way, and it’s been a decade since someone has last made that mistake.

Well the original article is also about RISC-V isn't a great ISA for embedded either, and how that's supremely disappointing because there's no inherent reason why the designers couldn't have learned from decades of ISA

There's an order of magnitude difference in speed requirements between file format parsing and image decoding, then another order of magnitude difference to video decoding. Even rav1d reuses dav1d's assembly (most of the actual ru

Still true for extended attributes, which Finder and Spotlight love to query.

Even backwards compatibility is optional in USB4. There are USB4 devices (SSDs at least) that will not function when connected to USB 3 ports.

Zero micro ops to be precise, that’s handled entirely at the register rename stage with no data movement.

Cortex A8 vsub reads the second source register a cycle earlier than veor, so that can add one cycle latency Not scalar, but still sub vs xor. Though you’d use vmov immediate for zeroing anyway.

Fine, you made me look it up. M1 Air defaults to 2880x1800 on a 2560x1600 display, which is a 1.125x scaling. Nowhere near the 1.5x you claim.

Apple never supersamples by 2x. Default MacBook Air scaling was around 1.1x iirc.

OP dances around the key context that this isn’t hidpi, but rather a 3rd party hack that uses hidpi rendering to supersample their “native” 4k resolution by 2x, since the end result looks more pleasing to them than the native 4k render.

And that itself is a recent policy change from just in the last two months; as of January United's official policy [1] matched the FAA's in only requiring checked devices to be powered down [1] https://web.archive.org&#

It’s really a question of whether a team believes bugs are defects that deserve to be fixed, or annoyances that get in the way of shipping features. And all too often, KPIs and promotions are tied to the features, not the bugs. Plus, I’ve b

That's why I said generally - once testimony is compelled, it can no longer be used against you. And the definite exception for compelling your name is if the government already believes that you committed a crime and is trying to fi

First, you have the right to say nothing at all; there is no requirement to incriminate someone else to protect yourself. Second, you can still generally invoke the 5th amendment during testimony even if you already claimed someone else did

by brigade 6mo ago
Most of the world also doesn't have the same degree of protections against self-incrimination that the 5th amendment provides. If someone shot a person with my gun, while the police can obviously ask questions, in the US I have the rig

It’s not a hard limit, especially if you aren’t pushing the frequency wall like Intel. AMD used to use a 2-way 64kb L1, Intel has an 8-way 64kb L1i on Gracemont, and more to the point, high-end ARM Cortex has had 4-way 64kb L1 caches since

ARM favored wider ILP and mostly symmetric ALUs, while x86 favored wider and asymmetric ALUs Most high-end ARM cores were 4x128b FMA, and Cortex-X925 goes to 6x128b FMA. Contrast that to Intel that was 2x256b FMA for the longest, then 2x512

Your first example is a CPU limitation that Instruments doesn't model (does perf?), but is still mostly better than Intel chips that are limited to 4 dynamic counters (I think still? At least that's what I see in the Alder Lake&#x

AFAIK Jyrki came after WebP was already announced to add lossless support; rather I’d consider Skal the creator inasmuch as it was originally just an image container for VP8 intra. He was working on WebP2 at the time Google rejected JPEG-XL

As someone who did predominately use stack overflow through Google search… I remember that half the time the top result was someone asking the question I had, only for it to be duped to a different question that didn’t answer the original.

For people in general these data brokers are a primary source of information for spammers, both political and semi-targeted. So they share responsibility for making calls from unknown numbers useless.

gAMA dates back to the days when hardly anyone had a clue about color primaries and colorspaces, let alone commonly tried to synchronize them across displays. It's explicitly ignored by everyone if the file uses any more modern method

Proper rate control for such realtime streaming would also lower framerate and/or resolution to maintain the best quality and latency they can over dynamic network conditions and however little bandwidth they have. The fundamental issu

Getting a streamer’s IP attracts DDoSes and doxxing, so yeah it’s generally considered a vulnerability to use P2P in games
