> "Everyone else" would have received the same breaks for that location and scale of project (less the $500MM you already mentioned). Amazon left the impression with their year long spectacle they were getting a special deal.

I experimented with just mov eax, 1 and found it be slower - though I didn't try inc eax. Using 16-bit registers is tricky because they leave the upper bits unchanged. Its easy to trigger a partial register hazard inadvertently. p.s.

That's only for the most obvious of cases lacking any nuance. Further in such cases the lawyers take much of the recovered so the plaintiff collects pennies on the dollar - while risking their professional reputation. Its a matter of

This is the first time I've heard an argument for the crazy high cost of the US court system. Realistically though the BATNA is no lawsuit at all because the plaintiff can't afford it.

Assembly is still quite useful in a number of circumstances. The compiler was generating terrible code for a ticket (spin) lock, and rewriting in assembly helped considerably [1]. Its also still the best way to get the most out of AVX and

AWS overcharges on their hardware to an absurd degree. The main problem is access to their network. You could host on your own hardware, but you'll never be able to offer the same QOS as a server directly inside an AWS datacenter - a

Three main reasons: 1) Modern NICs have multiple queues, and are best used with multiple threads. 2) A single core is not capable of saturating DRAM bandwidth. 3) Sharding is annoying, the more you can get out of one instance the better. Th

Redis is a popular program, it makes sense to spend the time to port it. But what your missing is the long tail, thousands of little programs scattered around - or edge cases in bigger ones. Working on a non-x86 platform makes you a second

An I beam is also a design not a material, if you want to be pedantic. You can buy aluminum ones.

I beams are quite safe if the fire retardant remains on (a major cause of the WTC collapse was the fire retardant getting blown off by the impact). Trusses on the other hand are quite dangerous in a fire. https://community.fireen

Seattle is just now allowing wood construction in high rise buildings. Previously they were an early adopter in mid-rise buildings which is why you see a lot of apartment buildings with exactly 6 stories around (1 concrete ground, 5 wood a

I always thought the way we talk about "unsecured" services was wrong. I leave my door unlocked all the time and have no expectation someone will come by and test it. Were they to see it unlocked they'd have no expectation
