Oh yeah totally, just more for context who might not be aware that there's still some practical benefits along with the historical aspect.

There's been a bit of a resurgence with the lower solar cycle, for mobile radios such as the KX3/2 and FT-817 which top out at 15W, having a mode that concentrates most of its power in ~500Hz of bandwidth(vs ~3kHz for voice) is a

Rather than casting scorn why not step up to the plate and do what the author has done here but for the architectures that you know? I spend a fair bit of time in the Arm space and didn't find the article incorrect, just PC focused. I

Yeah, that also depends on how modern your diesel is. The Kubota is much, much better on the particulate scale vs out old Ford thanks to a substantial DPF filter. Newer diesels, when not modified are much better than they used to be.

As an EV owner who also owns a 7klb Kubota CUT diesel is still ideal here for a few reasons. First it's easy to handle and transport, hydrogen has no shortage of issues there. It has a heck of a shelf life, my understanding is hydrogen

Hah, that truly is the exception. It's been a few years but if I recall correctly we did have a "smoke test" running on a jenkins box under someone's desk that booted a few levels with most of the game entities(they were

I think you're giving a bit too much credit to game logic codebases. They generally move at a pretty fast pace and change often(due to the iterative nature of what's "fun"). I don't think I saw a single unit test un

That's not speech then. If you're talking about compression, Q-codes[1] were invented long before most of us were born. [1] https://en.wikipedia.org/wiki/Q_code

You might want to let Motorola know since DMR needs needs multiple orders of magnitude(2-4 kbps) for their voice codec.

900Mhz will punch through some stuff and the spread spectrum chrip Lora uses will do non-LoS[1] under some conditions. The bigger issue is to get that capability Lora is a really low bit-rate(on the order of bits-per-second) and polled inst

I think that depends a lot on the area and local clubs, some are better than others. While this looks interesting I'm curious if they've done the numbers for Lora throughput. It's very, very low(which is also what makes it ab

If consoles were sold at a profit what you say may make sense. However building an open platform means you need to devote resources to it both from a capital perspective and opportunity cost. Driving demand towards the hardware, instead of

Yeah, that sounds about right. As someone who was on the dev side of the fence at that time one of the areas where Sony was pretty poor was the devtools. Other than some hardware capabilities of the profiler Microsoft blew away everything e

> Leafs usually charge to 100% unless you poke around and find the 80% setting. Uf. Unless there's internal limiting where 100%=90% that's not a happy thing to do to a pack.

This is a basic property of any 3-phase AC VFD motor, it's hard to see what's special here compared to a traditional electric drivetrain.

Congrats, Porsche has discovered the 3-phase AC VFD. The same technology that has been used for decades in diesel electric locomotives. It's well known that it has fantastic anti-slip properties. I'll have to dig up the source but

Am I reading this correctly that they couldn't be arsed to do DTLS/TLS and so they rolled their own lame crypto?

Why wouldn't they outlast? I'm not sure if hold up Subarus as the paragon of reliability given the headgasket issues that plagued certain years.

by vvanders 7y ago
Depends on the truck, our Ram EcoDiesel gets better mileage(30mpg) than any of our Subarus ever did. That said you see a lot of 3/4 ton daily drivers that only see a tow hitch one or two weekends out of the year.

Yeah and wifi is already pulling out all the tricks like FEC, CSMA and the like just to scale with usage. At the end of the day the internet is a packet switched and not circuit switched topology despite telecom pushing hard for circuit swi

All it takes is someone turning on a microwave down the block from you to drop 4-5 packets in a row and you get close to the 100ms number. Channel congestion in dense urban areas approaches the same limit, heck Ars was just talking about a

Yup, also if you look at people who write or have written netcode for a living, it's been pretty obvious where Stadia was heading for a while. You need to be able to reliably hide ~100-200ms of latency for any number of reasons. If you

Oh yeah, or metastability[1] when crossing different clock domains. The fact that it works by raw statistics(just add more flops until the chance is under some threshold) was definitely one of those surprising moments. [1] https:/&#x2

Transitions are hard, and I'm sure there's definitely that failure case. However if you look at EA and the acquire/in-house cycle they go through every 4-5 years, there's no way you can hope to be stable under those circ

Yeah, as an ex-gamedev as well there's a large divide between the values a devshop tends to hold and the publisher that finances your project. I've yet to see a studio acqui-hire that doesn't eventually head south as the publ

Great article, I wish the discussions around clocks had gone a bit more into how the tradeoff of pipelining vs longest operation ends up impacting designs. That and SRAM vs DRAM access latencies were the things that really connected the dot
