It's also blazing-fast. I've done some benchmarking on JSON -> in-memory borrow structs and it was pretty darn impressive while being fairly ergonomic to use compared to a streaming parser.

As someone who started pretty high up the stack(Visual Basic!) and kept peeling layers away out of curiosity I will say working with a CPLD/FPGA was really eye-opening. Latency difference between SRAM/DRAM and the "why"

I'd largely agree, there's a reason 3PH(and SSQA) are ubiquitous. If you support that standard it opens up a massive market of compatible attachments.

Yeah, I think in game dev there was also a culture of understanding that leaking that stuff just hurt whoever was working directly on it. Back when I was in industry we all knew what everyone else was working on including big IPs and next g

Anything that mentions Industry 4.0 and 5G together leaves me with a large degree of skepticism.

Yep, what's wild to me is there's actually a non-insignifiant overlap between radio and networks(ex: aloha from RF links in Hawaii ended up heavily influencing Ethernet and most of your cable modems use a variation of coding sche

Except that digital depends on... analog radio. I honestly wish there was better ecosystem for SSB 2M or robust SDR platforms. You have a host of digital modes on HF but most of the 2M/70CM radios/chips are FM/FSK.

Or sometimes you have an approach that is high risk/reward. That's totally fine to take as long as your aware of the risk and have mitigations or offramps at the right points if you find the path isn't viable.

Yup, there's also a big problem with gatekeeping and what's "true" ham radio. I wish it was different since you can do things with ham radio that are not possible without a license but then I look at the state of somethi

Yup, pretty much. When I left industry it was almost a 100% salary bump. I tossed 2 months of PTO(because the company wouldn't pay it out, per state law and I could never take it) and I made up the difference in the first few paychecks

Stock, I the game industry? That's a riot. In my time in that industry the only bonus/non-salary compensation I ever saw was a $20 Starbucks gift card for pulling a 90hr week before a major demo deadline.

Pedantically, none of them are C++ either.

The better comparison would be the 16" MBP and those look to be within about 1lb of each other. If your not going to be using the GPU heavily then you can just use a standard usb-c charger with should be similar in size to the MBP.

If you like this stuff data oriented design[1] is a nice framework that isn't arch specific(but can be extended to be if you need to make more gains that are arch aware). Back when I worked in the PS3/X360 days engines written for

Even "gaming" laptops have come a decent ways in size/form factor. I picked up a Zephyrus G15 a bit ago and it's pretty portable while having the ability to sink a good amount of wattage.

Their EMMC issue on the S was pretty egregious, that's something you get right in even basic consumer electronics. They also had numerous issues with door handles(I had two fail once the car was outside of warranty). There's thing

There's an incentive for chip vendors to not standardize since it makes migration hard and drives vendor lock-in. The CPU cores are one part but equally important is the peripherals and external featuresets.

No rain in space makes satellite a bit more viable, they don't mention throughput but I don't see how you get around the issue of atmospheric interference.

Pretty sure LTO already provides that functionality(I wish Rust had LTO on by default but it's fairly straightforward to flip on).

Oh totally. Half of games networking is finding out what you can "get away with" from an impact/user perception. Ex: play hit effects, sounds in a de-synched way locally but have major game events be authoritatively acked by

I think you may be indexing a bit into your exposure and painting the industry in a broad brush. I've seen impressive things done with Lua, from literate AI programming with coroutines to building compostable component based language c

Hierarchical component based designs have been around in game-dev for ages. I first used them in '05 but I remember prior art even before then. It was pretty common to have a declarative way to define components(usually through a scrip

Yeah, I can totally see the argument that it's a programming model that's well understood and you can get a productivity boost from that. However I don't think you can say that doesn't come with a cost, otherwise it woul

Everyone basically did Lua back in that era since it was so damn small. I had it running on 400kb of memory on the PSP, used it for multiple UI frameworks around that era on mobile hardware. Someone still hasn't built an equivalent to

Yeah, it's highly workload dependent. I've used restrict in anger to accelerate particle systems and we saw a significant speed boost. Even a 5% speed increase is nothing to discount give that it's "free" once they
