To translate to Rust, it would have been "we missed a single line Rust check"... This is a bug involving intersecting concerns and a deficit of cross-domain knowledge. It probably …

Most people don't plant an alfalfa field in the desert and then try to use the local municipal water supply for irrigation. Some of the folks looking to build datacenters to cash i…

It's near Springfield, Massachusetts. My point is not that evaporative cooling is necessary - it's that it's efficient, and therefore common. I found some 10-year-old info from our…

There aren't many heavy industries that dissipate 100MW of thermal energy, never mind a GW. Those that do - power generating facilities, large smelters, etc. - have very significan…

Historically, cooling alone has accounted for up to 40% of a data center’s electricity consumption The key word here is "historically". Modern data centers typically have a PUE low…

Water use isn't a myth. Our data center is mostly air-cooled, with 100F hot aisles and chilled water going to heat exchangers in every third rack position, although some of our new…

Note that for the businesses mentioned in the article, the service is the product. I don't care about service at a gas station - I want to fill my tank, pay, and get out. It's diff…

Note that there are a fair number of native speakers of English in Nigeria - more than in all but 3 or 4 US states. In addition, "non-native" English speakers in India (and Nigeria…

They overstate their results in the headline. In section 2, 34% of cases are found to have "substantive" disagreements differing by 2 or more buckets - True + Misleading, Mostly Tr…

If you run "make" in the papers/IBIC2013 directory you'll get this paper: https://cds.cern.ch/record/1743073/files/thbl2.pdf It's quite interesting - this isn't ethernet as we know…

"I wonder if this is actually true in the long-term though. If they were to flood the market with lots of high capacity memory, then I think our programs would start using more mem…

Jatin Malek on Twitter had perhaps the best explanation of the DRAM crunch: "The reason why RAM has become four times more expensive is that a huge amount of RAM that has not yet b…

> I’m curious what the performance of this implementation is Almost certainly crap. As the author states, it's a simple fork-on-request server, which was state-of-the-art in about …

Also note “Disks are like snowflakes - no two are alike”, Krevat, Tucker & Ganger, HotOS 2011. The number of tracks and bit density is not the same on different surfaces within the…

Read this paper: “ Revisiting HDD Rules of Thumb: 1/3 Is Not (Quite) the Average Seek Distance”, MSST 2024. https://www.msstconference.org/MSST-history/2024/Papers/msst... It has a…

Why should Backblaze back up their competitors’ data? And what use is it to you for it to do so?

Interesting. My only experience with Veracrypt is via a law firm I was consulting with, who used it to protect some files they were sharing with me. Law firm and their end client a…

It's a soda bottle - it fits in your water bottle holder, and you can replace it for a couple of bucks if it fails. 80 psi is pretty low pressure (typical narrow tires are 100-120)…

Look up the Osborne 1, the first "portable" (i.e. luggable) computer. They went out of business not only because they lost money on each unit, but because of how many they sold. Th…

I don't actually get your point. You dismissed the standard lock-guarded data structure as a "bogus comparison", despite it being the way every programmer is taught to write multi-…

It's not a "bogus and misleading baseline". It's precisely the way we teach people how to build thread-safe systems. And we teach them to do it that way because we've learned from …

What's not guaranteed for "normal" loads and stores on many architectures is the order in which writes become visible to other CPU cores.

That's what "lock-free" means. You still need to use the hardware mechanisms provided for atomicity. The whole point of lock-free data structures and algorithms is that sometimes y…

I would point out that most products are useless, and either fail or replace other products which weren't any worse. None of which prevented me from cashing my paychecks for the fi…

Are there any factual allegations on that page? All I could find was "the method described in the paper is not the method the authors actually used", without any elaboration. I'll …
