Everything is just buzzing

It's been two weeks since the state re-opened, and everything is just buzzing. The roads are packed, as are restaurants, bars, etc.

And it's not just the retail world that's buzzing. Here's a thoroughly bizarre (paywalled, unfortunately) article, with a thoroughly bizarre headline: Alameda office building shopping spree widens in tech hub.

A shopping spree for office buildings in the tech and biotech hot spot of Alameda has widened with the purchase of another property on the island city by a Bay Area developer.

With the latest deal, Paceline Investors has now spent $69.3 million over the last few days for three office buildings in Alameda, focusing on an area whose tenants are primarily advanced technology and life sciences firms.

The buildings are all located in Alameda’s Harbor Bay district, an area dotted with an array of companies with cutting-edge products and services.

Real estate firms have undertaken property purchases or launched development efforts that indicate they believe the Bay Area economy will be fueled by the expansion of tech, biotech, and advanced manufacturing companies.

That neighborhood is not far from where I live, and I ride my bike through there several times a week.

Indeed, there have been a lot of development efforts in this business park.

But the buildings are standing empty!

There are at least 10 large office buildings, brand new, completely vacant. Many were built during the COVID shutdowns, but a number of them were built as long ago as 2019 and have never found tenants. Other, existing buildings are dotted with "For Sale" and "For Lease" signs.

There are two buildings that are fully occupied and very busy:

Of course, neither of these are "advanced technology and life sciences firms".

But they sure make very good coffee and wonderful bread!

I definitely don't understand how the Real Estate development world works.

TestU01

While doing a bit of browsing on the Internet, I followed some links and came to a (relatively) ancient document: Pierre L'Ecuyer and Richard Simard. TestU01: A Software Library in ANSI C for Empirical Testing of Random Number Generators: User's guide, compact version. Département d'Informatique et de Recherche Opérationnelle, Université de Montréal, May 2013..

I guess it's truth-in-labelling, but I must confess that it's a bit startling when the "User's guide, compact version" runs to 219 pages!

But if you're at all interested in Random Number Generators, this is some amazing stuff. From the prologue:

TestU01 started as a Pascal program implementing the tests suggested in the 1981 edition of volume 2 of “The Art of Computer Programming”. This was around 1985. Three or four years later, a Modula-2 implementation was made, in the form of a library with a modular design. Other tests were added, as well as some generators implemented in generic form. Between 1990 and 2001, new generators and new tests were added regularly to the library and a detailed user’s guide (in french) was kept up to date. The f modules, which contain tools for testing entire families of generators, were introduced in 1997, while the first author was on sabbatical at the University of Salzburg, Austria. In 2001 and 2002, we partially redesigned the library, translated it in the C language, and translated the user’s guide in english.

These preliminary versions of the library were used for several articles (co)authored by P. L’Ecuyer, starting from his 1986 paper where he first proposed a combined LCG.

I love the brutal honesty that, after 28 years of effort, they considered that they had only achieved a "preliminary version of the library".

Random Number Generation is deep indeed, perhaps among the deepest of modern intellectual studies.

Anyway, I didn't know about this amazing effort until now, so here I am, some 36 years later, sharing it with those few who might not yet know of its existence.

There are all sorts of reasons why COVID data is hard to interpret

This detailed explanation letter from the Alameda County Public Health Department explains why overall COVID deaths in Alameda County have been restated from 1,634 to 1,223:

Alameda County previously included any person who died while infected with the virus in the total COVID-19 deaths for the County. Aligning with the State’s definition will require Alameda County to report as COVID-19 deaths only those people who died as a direct result of COVID-19, with COVID-19 as a contributing cause of death, or in whom death caused by COVID-19 could not be ruled out.

Alameda County has appx 1,671,000 people.

So, prior to this adjustment, we thought that appx 0.1% of the population had died of COVID so far; aligning the definitions with national standards shows us that 0.07% of the population has died of COVID so far.

Meanwhile, in more good news, the county continues to inch closer to complete vaccine coverage, with 1.98 million doses administered to this date.

And even closer to home, in my hometown 85% of the population aged 12+ are at least partially vaccinated; 71% are fully vaccinated. For the county as a whole, those numbers are 79% and 64%.

Vaccine Complexity

Through a combination of the amazing Tableau data analysis software, applied to the extensive California Open Data Portal datasets, you can now see an amazing breakdown of COVID-19 vaccination data down to the individual ZipCode level, across the entire state.

Spending some time with this visualization tool is amazing. Not only can you learn a lot about the situation across various areas of the state, the challenges of "vaccine equity" become crystal clear.

Less: a very short review

When I started reading Andrew Sean Greer's Less, I didn't understand why I was reading it, nor what all the fuss was about (Less won numerous prizes, including the Pulitzer).

But I found myself continuing to read, page after page, chapter after chapter, and quickly I became captivated and enchanted.

It's hard to explain why Less is so much fun to read, but almost every single page is graceful and sincere while still being outrageous and hilarious.

And that's a hard thing for a book to do!

Our hero, Arthur Less, doesn't take himself too seriously, and doesn't take the world too seriously, and yet still somehow has an entirely serious observation to make on almost everything, nestled down there in betwixt all the sly pokes and rude chuckles.
