Yup pretty much. Zero-copy deserialization implies one large read into a block of memory(or mmap) which forces a specific layout. From there it's straightforward to follow standard data oriented design principals.

Flatbuffers is pretty great, one side benefit of these types of technologies is you can also use them to structure your memory accesses. I've done this in Java to do cache aware reading to pretty great success.

Yeah, This American Life had a great podcast about the NUMMI[1] plant that covers this in great depth. Pretty fascinating stuff. [1] https://www.thisamericanlife.org/561/nummi-2015

That existed for Microsoft employees a while back(not sure now). Heard many stories of people using it to get out of parking tickets rather than anything serious.

As someone who's spent a good amount of time in both GDB and Visual Studio don't be so quick to knock the dev tools on Windows, they're really quite good.

All abstractions leak just in different degrees. Perf/memory is the most common but there are others as well. Your ivory tower parser/data format/framework is great until you need to fit it in 1/4 the memory or MIPS. Tha

You can steal a trick the motorcycle community discovered a long time ago, some water + soap on the windshield prevents condensation. Our '83 Vanagon doesn't have AC, it can be uncomfortable but sure isn't the end of the worl

Definitely, I'd put it on the mission criticality list right below inflight wifi.

Well, you can reboot the system while driving(both console and dash), nothing special happens other than the AC turning off for a brief period of time. Brakes, wheel, throttle all respond normally. Source: Done this a few times to clear bad

Could just be a coil of wire with a LNA in front of it. Would be curious about the details as well.

Yeah, that's pretty darn impressive to do that with a magnetic probe, no physical connection needed. Gone are the days of putting a sense resistor between the safe and battery, just pick it out of the air now.

> over both powerline Ack. Please don't tell me this isn't a widely supported thing. powerline communication wreaks havoc on RF spectrum, esp in the HF range.

+1 Just put in a bunch of Caseta dimmers this week and agree. I wish they had the same design as their other dimmers(one large button, rocker for dim) but they're still a great product regardless.

Agreed, it's not as impressive as in person but I've always liked seeing the Cushman Powerhouse #2[1] when I drive 101. I feel like we should take pride in our infrastructure and making them architecturally attractive is a great w

Ah, I see we're going to argue semantics here. You can get a PTO and 3-point on a telehandler, doesn't make it a tractor. What you're talking about there is a riding lawn mower. I also didn't say that there's any co

Not sure why you're talking about RLE and Gators as I was only talking about compact tractors. You could say the same think about Kubota as the assemble their B/BX models in the US(they however don't outsource the engine). Th

They're also really common for interconnect fabric on reasonably complex systems. Lattice does really well in this space with their low-cost FPGAs/CPLDs.

My uninformed guess is that the F-15 were scrambled to intercept if the plane started heading towards Bangor, Bremerton shipyards or JBLM. Lots of military bases and critical infra up in the PNW, thankfully it didn't appear to be the c

I looked at pfsense before going with Ubitquti/UniFi. Have to say I'm really happy with it, breeze to setup and does 99% if what you want to do out of the box.

Another +1 for Ubiquiti. Had a bunch of high end prosumer stuff, ddwrt/tomato, etc. It really is fantastic stuff at least on part with ddwrt and well matched hardware to boot. Their cloud management stuff is solid(and free with spare P

Not denying that Java is/was popular, just that it's popularity was curbed by the lack of value types, direct memory allocation(unsafe) and a few other performance sensitive features. The same reason that you see Unity dominate th

Hardly, I spent a lot of time in spaces where Java and others languages would be considered. If there was ever any hint if performance being a bottleneck we chose C++ over it. Even moreso because unsafe doesnt exist on some variants(Android

Yeah, they're quite something. They had one on display at one of the Miramar Airshow a few years back and it's really a unique airframe in person.
