Permanent calendar proposed to eliminate leap day

“Those born on Feb. 29 know they exist, but the computer at the DMV is skeptical.”
Subheadline for the Wall Street Journal article today about how Leap-Year Babies Fight a Lonely, Quadrennial Fight for Recognition
Today being a day that comes only every four years is special—even more so now that my niece delivered a leap-year baby girl. Unfortunately, this precious little leapling (“LL”) faces a lifetime of calendar kerfuffles with computer systems that do not compute February 29th birthdays. However, a solution is at hand: the Hanke-Henry Permanent Calendar (HHPC). By HHPC’s reckoning this special day is March 2nd and comes again on Saturday next year and every year thereafter—no need for LL’s parents to wait four years to celebrate her first birthday.
Being that my birthday would always fall on a Monday, I cannot build much enthusiasm for the HHPC feature of any given date always falling on the same day (LL lucked out, though). Other off-putting days are Independence Day being on a Wednesday and Halloween being eliminated due to October ending at 30 days. But the weirdest aspect of HHPC is the “Xtr” week every 6 years. This year of 2020 features an Xtr, for example. Minnesotans do not need 7 more days of winter!
PS. Watch the video to see what would happen, if we did not add a day every 4 years: Eventually summer would become winter!
Major League Baseball experimenting with robot umpires
Posted by mark in sports, Uncategorized on February 19, 2020
After a somewhat successful* year-long trial of automated balls and strikes (ABS) in the Atlantic League, MLB will bring in these ‘robots’ to second-guess their human umpires at nine of Florida’s spring-training games. The ABS system makes use of TrackMan radar technology, already in play for StatCast.
After MLB’s tech-team improves ABS’s reliability and accuracy, it might be worth using, but only if it speeds up the game. Using ABS simply to challenge calls will just make things worse, while eliminating the spectacle of on-field blow-ups by volatile managers like Billy Martin (former Minnesota Twin). When the calls are made by invisible radar, who do you throw the dirt at?
“You turn back (to the umpire and say), ‘TrackMan?’ They say, ‘Yeah,'” “‘Well, I’m not going to argue with you.’ Because it’s the robots.”
Southern Maryland Blue Crabs outfielder Tony Thomas commenting on the experimental use of ABS in the Atlantic League
PS. When the baseball robots get smart enough to call balks, then we’d all best bunker down for them taking over the world.

Assessing the threat from Wuhan Coronavirus (2019-nCoV) via quantitative analytics
“In God we trust. All others must provide data.”
Dr. William Schaffner, a preventive medicine specialist at Vanderbilt University Medical Center, quoted by NY Times on 2/2/20 in their report that “Wuhan Coronavirus Looks Increasingly Like a Pandemic, Experts Say”.
Stay calm and carry on is a good mantra for these unsettled times. But it pays to keep an eye on developments with a critical view on the facts so far as they can be ascertained. Here are some interesting statistics and data-driven observations on the impact thus far and in future of 2019-nCoV from the New York Times:
- Fatalities now come to 425 in mainland China as of Tuesday morning according to this latest news, eclipsing Chinese deaths from SARS (349). For a view of its spread throughout Asia, see the Coronavirus Map via the link above.
- For a very enlightening interactive-graphical view graphics see this in-depth report.
Keep in mind that much remains to be determined. For example, it may turn out that 2019-nCoV for better (less fatal) or worse (more infectious) may turn out to be more like 2009 H1N1 Swine flu than SARS.
You, like me, may be curious about the effectiveness of wearing a mask. From this NPR investigation, I surmise that N95 respirators, such as those made by 3M, work best, but only if fitted properly and worn with great discipline in not touching one’s face. In any case during this flu season, we all need to wash our hands with soap and water often (hand sanitizers don’t work nearly so well by my reckoning) and stay home if we get sick.
For what it’s worth, that’s my take for now. You all must make your own judgments. All I suggest is that you not let fear rule—assess the data and adjust your thinking as more accumulates. But best you be conservative on the safe side.
PS. Those of you who fly frequently are well-advised to check out this advice from yesterday’s Wall Street Journal. I am comforted by the statistic of 99.9% particulate removal and thus “the cabin air environment is not conducive to the spread of most infectious diseases” per the CDC. However, as always, it’s best to be careful during times when the flu and/or other viruses run rampant.
