While the idea of data-deduplication does apply everywhere, this specifically depends on the APFS CoW data feature, so it's not applicable outside of macOS (or APFS Volumes)

There are two aspects to compute performance: latency and throughput. There has been a ton of work to improve throughput, but that's often come at the cost of latency, because a gr…

Fun fact: the Jeff Dean Facts was started by Kenton Varda (kentonv around here [1]), as a joke inside Google. He has expressed regret that it eclipsed Sanjay Ghemawat, with whom Je…

Granted, Apple does do this weird thing where you're invited to use your personal iCloud (/Apple) account for work-related things (I suspect because they're just bad at supporting …

I suspect SPF is used because it's cheaper than performing cryptographic checks for each email. A (cached) DNS lookup and IP check on a connection is comparatively cheaper.

Tangential, but about this: > I am creating a RAIDZ1 (RAID 5) zpool. That means 1 drive redundancy in-case of failure A friend once told me that RAID5 has a high latency cost, beca…

I want to cheer (again) for my 2020 Ford Escape. Its infotainment design was a significant differentiator that led to my selection after testing a dozen different models across all…

I wonder how they achieve the lighting effect from the banner picture? It doesn't look like the Adafruit panel has backlighting built-in, and there isn't anything added in the proj…

I've been hearing that for years, and I'm still waiting. Incidentally, my 2020 Ford Escape has buttons, which was a strong selector. I hear it's because it was designed for the Eur…

eh, every 6 months to a year I bring the car in to the dealer to handle the stack of pending recalls, during which I get a rental, courtesy of Ford. It's not much of a deal for me.…

It's impressive all the recall notices I get on my 2020 Escape Hybrid. At this point I joke with my friends that they're love-letters from Ford. (most of them are for fairly innocu…

> instead of unobservably better performance That's... quite the choice of words there

Are referencing the 1998 short story "Taklamakan" by Bruce Sterling?

A common confusion; this interpretation only applies to OVH. ref: https://www.reuters.com/article/world/millions-of-websites-o...

I thought it meant "electricity has ceased to be a physical phenomenon in the general vicinity of our servers"

yeah, it's funny how so many think the beginning of the S-curve is an exponential. Granted, we don't know when the S-curve will inflect, but predicting too great an outcome is just…

There is a field of competitive compression algorithms, where time and computation are not factors. People have made compressors that take hours (days?) to compress the test corpus…

Rust doesn't have an ABI [1]. Swift needed one to be a useable application language: https://faultlore.com/blah/swift-abi/ (written by a core Rust developer) [1] apart from the bas…
