When you're paying $7k per core for sql server you're happy to pay big $ to squeeze value out of every one of them.

This terrible price for sql has been nagging me for a while, ever since we've changed out db from sql to postgres at workplace. We're getting basically the same performance for way less so I'm wondering why you'd pay microsoft all those big bucks

Notorious b.s.d. posted:yes, cell and xenon are similar here's wiki fuckin pedia on the topic quote:The PPE was designed specifically for the Cell processor but during development, Microsoft approached IBM wanting a high performance processor core for its Xbox 360. IBM complied and made the tri-core Xenon processor, based on a slightly modified version of the PPE with added VMX128 extensions.

Sql server has columnstores, temporal tables, change tracking, basic graph support and a good ide. I don't think postgres has any of them but I might be wrong. The real reasons to use it are probably enterprise support and weird AD integration stuff though.

that sounds about right for high end radiation-hardened cpus, although it also does depend on what’s your plan for space. if you are sending something to our gas planets or towards sun then i really hope you can pay up - poo poo around are Earth is protected by its magnetosphere, so well that there even are toy projects related to sending micro-nanosatellites with x86 into leo and whereabouts

ya getting dumb toys into leo is typically a nice mix of cheap enough to launch there + low stakes if it fails + decent natural shielding that it doesn't really matter and you can use w/e

xilinx has several radiation qualified fpga models too, wouldn’t be surprised if lots of modern space hardware uses them instead of a rad750 or w/e basically, if you needed the fpga for other reasons (eg to do dsp for software defined radio), and your control software doesn’t need high performance, you can just throw a soft core or two into your fpga instead of designing in a discrete extra part. xilinx’s own microblaze soft core gives you a ~200 MHz 32b risc without using much fpga fabric it should be noted that despite the hardening and certification for space, designers still have to pay a lot of attention to poo poo like secded ecc for state machine state words, watchdogs which reset the whole shebang if anything goes too far wrong, and so forth. radiation: not great for reliability, who knew
