Two inventions were required for BEV's to compete with even 1920's ICE vehicles: the power MOSfet (1970's) and the Lithium-ion battery (1990's). GM was about to put Lithium-ion batteries in the EV1 when the project was

Why not both? Part of why dark matter is such an attractive explanation is because there are no constraints on it. Unfortunately this seems to have relieved pressure to explore and test modified gravity.

I don't understand why consensus jumped to the conclusion that there must be a new form of undetectable matter instead trying to figure out what we don't know about gravity. Theoretical particle physics is even worse. There haven

The ability to synthetically generate real words could be considered a feature -- a sign that it is working well. Was the definition correct?

Are these being generated in real time or are the pre-generated and pulled from a database?

Here is a complete simplified Kahan summation test and indeed it works with -O3 but fails with -Ofast. There must have been something else going on in my real program at -O3. However the original point that 'volatile' can be a

I did tests on Kahan summation recently on my macbook pro and -O3 defeated the algorithm while -O2 did not. Declaring the below variables as volatile restored error compensation with -O3. The relevant code is: kahan_y=g_sample_

> "volatile" does not mean what you think it means; if you're using it for anything other than interacting with hardware registers in a device driver, you're almost certainly using it incorrectly. Another "correc

It wasn't just old hardware. Upgrading from SunOS to the early Solaris versions on the same hardware was noticeably slower. 2.4 was the first usable version IMO and it improved a lot by the time 2.6 was out (but then they dropped sup

NaN usually indicates a bug or algorithmic problem, but not always. I have had cases where I need to detect NaN, present a useful message to the user even though everything is working as designed.

Pre-1992 it was SunOS and yes that is exactly what we want (without all the security holes). SunOS was BSD and Nirvana as far as Unix goes. Solaris was SysV and quickly earned the nickname "Slowlaris". For me FreeBSD is the funct

I don't think it's reasonable to compare cryptocurrencies to chain letters. Chain letters' sole purpose is to enrich early adopters at the expense of later participants. While early adopters of cryptocurrencies frequently do

The issue is, and the reason I submitted this article is dopamine is being grossly misrepresented as the tangible enjoyable feeling from an activity ex: "dopamine squirt" in so many articles these days.

Please stop calling dopamine an addictive rewarding neurochemical (2017)(psychologytoday.com)

One example in networking of a "best practice" that quickly turned into a "worst practice" is disabling auto negotiation. Back in the mid 1990's when 100 mbps nic's first came out implementation of the new au

I've used ZFS on FreeBSD for many years and it's absolutely rock solid. There was even a case where an IPMI had been hacked and the attacker reformatted the disks for Windows 10 and I was able to recover most of the the data.

In truly bad situations where failure appears to be imminent, wouldn't it be safer to start rsync'ing whatever files you can to a reliable disk or another server?

The line between genius and crackpot is often very blurry. It seems most of his problems are from "guilt by association" and the rest are from doing serious work in very unconventional ways.

The only meaningful comparison is to the energy usage of the legacy banking system. Banks have a lot of data centers, office space, employees who drive to work etc.
