Yes, this is a reasonably common strategy. It's how Cassandra's batch and group commit modes work, and Postgres has a similar option. Hopefully NATS will implement something simila…

The Samsung consumer drives definitely don't do well under sustained high write workloads. The SLC cache fills up after a while, and write speeds drop drastically. The They also ha…

vB itself isn't FOSS. XenForo is the best alternative by a fair margin, but for FOSS there's good old PHPBB.

Yeah, even in a case like this where they turned out to be right, it might be one of those "predicted 15 out of the last 2 recessions" sorts of things.

Wouldn't have necessarily had to be nearly as bad as IE6 for security, either. Just lock the special browser to facebook.com only, or even just the ads API, and there's not a lot o…

It's a bit hard when the temperature deltas are so small, though. It probably works well if you're pre-heating air before the main heat source in a very cold region, but otherwise …

I've heard they are actually closer to production, but yeah.. HAMR's been "a couple years away" for over a decade at this point, I think.

I haven't dug too deeply, but it's unclear whether anything but the Asrock Rack boards have full validated ECC implementations for Ryzen (vs just using the memory but ignoring ECC)…

Pretty far. Since we cram so many drives into each server, our total server count is actually relatively low for the amount of storage we have. I'm not sure exactly how many units …

It definitely doesn't write it to disk first. It's basically a pipe() under the hood, but exposed as a file descriptor. Downside is that seeking doesn't work, but that shouldn't af…

Disclaimer - Backblaze employee here, but just speaking for myself: It was.. sort of cheaper. They didn't actually build the servers, and as described the server wouldn't work (onb…

Hi! Backblaze employee who did some of the LB stuff here. It's relatively standard/straightforward. There's a L4 load balancing layer using IPVS and ECMP-via-BGP, then a custom app…

The US was too little and too late with testing for contact tracing to work. It might become possible again if the number of cases gets low enough, though.

The exact numbers? Of course not. Especially early on, they were suppressing information in addition to just not having complete information themselves. The cat's out of the bag at…

It's not just intubation but varying other protocols for treating sepsis, ARDS, etc depending on the exact set of symptoms. Even the ventilator itself is far from "hook it up and l…

Probably a lot of the other way around as well. Google employees likely use Chrome and Docs/Sheets heavily, so they get a rapid high-quality feedback loop with any bugs or performa…

"prone to" is putting it mildly. ICMP echo requests tend to be processed by the often relatively anemic control plane CPU rather than ASICS and are at the bottom of the heap in ter…

In addition to the SATA port multipliers, they'd need actual SATA PCIe cards. Basically nobody makes a motherboard with onboard SATA that supports port multipliers.

That's the price being paid for the storage, but is it actually covering the cost of providing that storage? Or is it just 100-300 people who thought "Huh, neat, I'll toss a host o…

Even if it had slots for the splitter cable, Intel and AMD onboard SATA explicitly doesn't support port multipliers as far as I know. You can buy PCIE SAS cards that do for relativ…

The trick is this: the chances that a specific fund will do well that long via luck are very low, but the chances that there exists a fund among all that exist that has done well v…

I'm not too familiar with JVM internals or Spark, but I know with Cassandra at least there's a cost to off-heap memory. You gain in GC, but eventually you have to move that data in…

A bit apples and oranges, though. The ASCI Red is a general-purpose computer that ran whatever you wanted via the full x86 instruction set. The Xavier and Tesla chips are basically…

Colo can mean "rent a suite from DRT in one location and a building in another" in addition to space in a rack. Lyft's probably around that size (and it's a good idea to do some co…

Depends on the case. Facebook at least generally replaces drives as they go. In a pipelined fashion rather than as they fail, though. So, a given drive failure doesn't lead to imme…
