Best of luck getting a good deal for new hardware right now from anyone right now. All hardware pricing negotiations these days start with give us your company credit card, drop your pants and bend over the table.

Does any other architecture allow split cacheline atomic operations across sockets?

They also fucked up their parity RAID repair so that the next disk failure on a different disk will destroy the data, argued that the pathological B-tree performance reported by a user couldn't be real, because they didn't underst

No reasonable person has ever argued that a consumer buying a (digital) copy of a game obtains the exclusive rights to the game. This is such a cheap embarrassingly stupid attempt to come up with a straw man. I'll listen to Sony man

A CDN *cache* server is a special case. Netflix cache appliances can accept the risk of running FreeBSD -CURRENT and upgrading half their fleet to the latest snapshot every ~2 weeks and we thank them for battle testing FreeBSD's active

If you run the latest (laptop) hardware you may still have to track stable or backport some patches from -CURRENT.

You're just wrong. FreeBSD stable branches are the development branches from which new minor releases (with a stable ABI) are forked. If you want to be pedantic you want to follow the releng branches for most production deployments (re

The ARM v7M architecture helps a lot here because the NVIC supports priority inheritance without disabling interrupts. Yes you have to assign your priorities correctly and yield CPU time for anything compute bound, but again the architectur

A 1GHz superscalar Cortex-M7 can still hit a 12 cycle interrupt latency if the system stack is kept in the 2x32 bit wide zero cycle dTCM, and the VTOR and handler are in the iTCM thanks to lots of bandwidth and a reasonably short pipeline.

One advantage they have for building larger systems is that they allow you to crack stores into two parts. The part that has to retire in order for the local CPU and the write back to memory. Now assume you have multiple banks of memory and

Should we also ask the Saudis what drawings to punish by beheading or the Taliban which writings to punish by stoning?

They're also too stupid to understand that they've been dropping UDP datagrams with src port == dst port and < 1024. This obviously breaks IPsec IKE. I showed them dummy traffic captured with netcat and tcpdump, but they refuse

A lot of the important applications took a while to get ported. Also the last two generations of G4 hardware just overclocked basically unchanged chips. The 12" G4 laptop was infamous for slowly cooking your junk with their titanium sh

What people did or planned to do with IPFS is pretty silly, but the idea of content addressed storage with cryptographic (not in a crypo coin way) names makes a lot of sense. It would make for a great software distribution method e.g. your

Running xattr -d to strip the quarantine flag is just a slight annoyance. I think next big outcry will be the removal of Rosetta 2.

That says more about your lack of both knowledge and imagination than the vendors. Intel added SMM for software backward compatibility so DOS didn't have to learn how to suspend and resume on early laptops. Instead of waiting for opera

The documentation was locked away behind NDAs when the faulty BIOS leaving it reachable was discovered. Look at the publication dates.

Yes there is a harmless explanation. The VIA C3 is a fairly simple CPU design that cracks x86 instructions into an internal simpler instruction format. Some complex x86 behaviour is normally implemented by lengthy microcode or complex state

Strange choice to go for a raycaster with sprites on the N64. The hardware is basically begging to be fed textured polygons.

This is a common pattern a compiler should recognise and optimise into an efficient data and control flow. So much for a sufficiently smart compiler. shrug

What's wrong with using BFD for IP over Ethernet? You can put whatever control plane you want on top from simple static route priorities to full blown eBGP and everything inbetween.

DES doesn't accept 128 bit keys. It's native key size is 56 bits which was commonly extended to 168 with 3DES (encrypt-decrypt-encrypt).

One of the reasons Japan uses wood for construction is that combined with their traditional building techniques it results in earthquake resistant buildings.
