It uses the same pins, but it doesn't actually use Ethernet. I'm pretty sure it's IEC 60958/61937, like SPDIF.

"They paid me $400k a year whereas the median income in the US was like $30k a year" would be enough for a lot of people to forgive you for the egregious crime of working for Facebook.

True. NXP chips can also be found in devices made by vendors who are too small to get a response from Qualcomm or NVidia. Unless you're moving thousands/millions of units, those big dogs won't even entertain you with a quote.

I've never read the book, and had no idea about the plot. I didn't really enjoy the movie. I'd still recommend watching it though. It was clearly done well - I just didn't personally like it. It was hard to become invest

I normally like his stuff, but I did find relief in the one scene during the final fight where the background "music" stopped for a few seconds. That's when I realized how annoying 2 hours of continuous background pad can be.

NXP manages to do it fairly well though. Their chips have excellent upstream support.

You could always do it yourself if you feel it's overpriced. It's no different than software engineers charging $300/hour consulting fees. Sure, they're just typing on a keyboard (or running some wires in this case), but

L3 is SRAM on all AMD Ryzen chips that I'm aware of. I think it's the same with Intel too except for that one 5th gen chip.

I mainly just use them when I run on the treadmill. The wire gets a little annoying since I don't have a shirt on to tuck it into.

The overall bandwidth isn't affected much by the distance alone. Latency, yes, in the sense that the signal literally has to travel further, but that difference is miniscule (like 1/10th of a nanosecond) compared to overall DDR ac

The M1 still uses DDR memory at the end of the day, it's just physically closer to the core. This is in contrast to L3 which is actual SRAM on the core. The DDR being closer to the core may or may not allow the memory to run at higher

It always seemed pretty obvious to me. Everyone is fake on social media, but it's not always apparent that it's fake (it it was, then it would defeat the purpose). What happens when it seems like literally everyone is living a bet

I was able to do this on Ubuntu 16.04 with CUPS. It was surprisingly easy. I just googled and followed some guide on the first page of results.

That reminds me of a custom Linux device driver that I worked with in the past. It implemented "mmap" so that a user application could map a ring buffer into userspace for zero-copy transfers. It used lazy mapping in the sense tha

What happens when they all race to store to the same memory location? I guess if they all run in lockstep it doesn’t really matter? I’ve worked with some ARM SoCs from NXP and I could have sworn that one core comes up first and the others g

Little soft core CPUs like this are often incorporated into larger FPGA designs to handle sub-tasks that would otherwise be annoying to implement with pure logic. Think something like a simple CLI console to configure low level board functi

Yep. Matrix is a decentralized alternative (provided you don't just use the default homeserver).

I like the model of charging for open source software, perhaps with slightly better support in return. It doesn't have to be as serious as the RedHat model either. Something like how Bitwarden does it seems reasonable to me. You can ru

I wonder how much longer DNS based ad blocking is even going to work with things moving to DNS over HTTPS.

> unwinnable It seems winnable so far if you look at the Xbox One and later, at least. I'm not aware of anyone successfully modifying game code on those consoles. The downside is that it a requires a completely locked down system.

No it doesn't. LUKS encrypts a block device, and then the filesystem is instantiated on that encrypted block device. No file names are visible.

All of Intel's Ethernet/WiFi adapters have open source drivers on Linux too.

I guess the fist step could be to handle it in the C library using some capability check and function pointers, then perhaps later on in the compiler if some mcpu flag or something is provided.

How come? What is special about how memcpy works compared to a regular load from BAR memory?
