    Nervana is dead (official statement in article). Got the news about it Friday & have a really hard time explaining it. Architecturally, Spring Crest is simply superior in so many ways. Nonetheless, someone with the throw-money-at-the-problem idea won.

    Pfft. It's not a 144 TOPS computer, it's 72 TOPS. Those two chips are independently operating on the same exact execution plan simultaneously in lockstep for safety. It's not meaningful and misleading to inflate the peak TOPS by summing the two chips.

    Intuitively, the day and month must be the same. Therefore 12 such d/m-m/d possibilities exist. Turns out they are actually ultra-rare (if I didn't screw up): 01/01/1010 11/11/1111 02/02/2020 12/12/2121 03/03/3030 04/04/4040 05/05/5050 06/06/6060 07/07/7070 08/08/8080 09/09/9090

    Ok, this is take number two. Tomorrow (02/02/2020) is a palindrome and is the first such -global- occurrence in 909 years (11/11/1111). The next time this will happen appears to be in 101 years (12/12/2121). (global = works for everyone day/month and month/day)

    Actually, none of the replies I got were palindromes.

    Today I realized how valuable Google Streetview is long-term when I needed to check out what something looked like a 13yrs ago. Imagine how amazingly valuable it will become if they keep it up for the next few decades. People able to look at any place on Earth a 1/2 century+back.

    Due to , Apple's just told investors that the company began to limit travel to China to "business critical" situations last week. Suppliers in the Wuhan area have alternative sources.

    2019 Enterprise, Embedded and Semi-Custom net revenue was $2.22B, which is actually down from $2.35B in 2018. The reduction is largely due to semi-custom sales revenue but EPYC isn't hitting major momentum to offset it, at least not yet.

    AMD reports a record q revenue of $2.13B, up 50% YoY, a record annual revenue of $6.73B, up 4% YoY. Computing&Graphics up 69% YoY due to Ryzen&Radeon. Enterprise, Embedded & Semi-Custom up 7% YoY due to "significantly higher" EPYC sales. Full-year 2020 they expect 28-30% growth.

    Local library had a whole bunch free 'obsolete books' for the taking. Along with a pile of finance books I found this treasure.

    People, take the Coronavirus seriously. Stay safe. A lot of us are going to international conferences = higher risk of exposure. Wash hands often & thoroughly w soap. Carry pocket hand sanitizer. Minimize handshaking. Avoid touching high-touch surfaces & your eyes/nose/mouth.
