Google reports on community lockdowns

Google has released “COVID-19 Community Mobility Reports”, Reports to help combat COVID-19, which use anonymized Google location data to report on how well communities are following shelter-in-place and other lockdown rules.  The delay in the data is enormous (they are reporting March 29 data on April 3), which seems rather strange given how much compute power Google has—they should have reports with delays of no more than an hour or two.

I looked at the report for California, which gives a county-by-county breakdown.  Here are the numbers they report for the state and for Santa Cruz County:

activity CA Santa Cruz County
retail and recreation -50% -55%
grocery and pharmacies -24% -27%
parks -38% -40%
transit stations -54% -57%
workplaces -39% -41%
residential +15% +15%

The percentages show the reduction from baseline behavior (which is probably based on last year—I did not read the methods very carefully).

It looks like our county is doing only slightly better than California as a whole, which is probably not good enough, as we have one of the worst ratios of intensive-care units beds to population (particularly to elderly population)  in the state.

Within California, San Francisco County, with one bed for every 532 older residents, and Los Angeles County, with 847 residents per bed, both have greater bed availability than does Santa Cruz with one bed for every 2,601 older residents. https://californiahealthline.org/multimedia/a-lack-of-icu-beds-amid-pandemic/

In fairness, some of the less-populated counties in California have 0 ICU beds, so may be in worse shape than Santa Cruz County with 22 beds, but we already have 9 hospitalized of our 59 cases, and our numbers are still growing exponentially.  In usual times 22 beds for 273,000 inhabitants is enough for us, because we can usually send people over the hill to Santa Clara County, but I don’t think that is going to be an option during the pandemic.

The county is planning on adding more hospital beds, in places like Simpkins Family Swim Center, but those will not be ICU beds.  They will probably be short on ventilators also, when the wave of cases hits in about 2 weeks.

Google News fix

I’ve been moaning about Google News having broken their website for months now—their “new” News site eliminated all user customization, made it impossible to remove useless sections (like Sports and Entertainment), paid no attention to “show me less like this”, showed lots of “news” articles that were just infomercials, and generally was piss-poor imitation of a news aggregator.

I’ve started looking at other sites, but not found any that are as good as the site that Google threw away.  I read my news on my laptop, not a phone, and I want a content-dense, laptop-friendly web interface—eliminating most of the competitors in one stroke.

Today, in browsing once again for workaround to Google’s decision to kill News as usable interface, I found someone point to a way to get the old interface back, though only a frozen version of the customization—further personalization seems to be disabled.

https://news.google.com/news/feeds?output=rss&q=%

seems to get back the interface I used to use and like, but populated with current news. It is annoying that I can’t tweak the personalization any more, but I can live with that.

I’ve also been able to include Google news searches in Inoreader (the RSS reader that I use), with URLs like

https://news.google.com/news/feeds?output=rss&q=karplus%20-martin

though I get a warning that the URL is deprecated, directing me to one of Google’s new useless feeds.  It still works for now, and I’m hoping that enough of Google engineers use this old backdoor that they won’t close it and force everyone into their ad-driven propaganda site.

Google has a long history of making decent tools, only to break them or throw them away when they did not draw in enough ad revenue (I’ve been burned by both Google Reader and Google News).  I am worried about UC having made such a huge commitment to Google products (Google Drive, Google Docs, Google mail) for so much of its day-to-day work.  I suspect that Google will pull the plug without warning some year soon, and UC will be left without any alternative systems and without the personnel to maintain them even if it had the computers and software.

 

Update 28 Oct 2018: the Google News fix isn’t quite as useful as I thought.  Not only is personalization not modifiable, but all the links to sections (including the side navigation panels) just go back to the useless new main Google News page. Sigh, I guess I will have to keep looking for news aggregator that does a decent job.

Update 14 Nov 2018: It has gotten worse.  Now https://news.google.com/news/feeds?output=rss&q=% produces the same junky sections as the main Google News site, so it is goodby Google, it was nice while it lasted.  Anyone know a decent news aggregator?

Using Google ngrams

I’ve found https://books.google.com/ngrams to be a very handy tool while writing my book. It has helped me answer such questions as which is the preferred term, “bypass capacitor” or “decoupling capacitor”? “bandpass” or “band-pass”? “passband” or “pass band”?

https://books.google.com/ngrams/interactive_chart?content=bypass+capacitor%2Cdecoupling+capacitor&year_start=1940&year_end=2015&corpus=15&smoothing=3&share=&direct_url=t1%3B%2Cbypass%20capacitor%3B%2Cc0%3B.t1%3B%2Cdecoupling%20capacitor%3B%2Cc0

https://books.google.com/ngrams/interactive_chart?content=bandpass%2Cband-pass&case_insensitive=on&year_start=1920&year_end=2008&corpus=15&smoothing=3&share=&direct_url=t4%3B%2Cbandpass%3B%2Cc0%3B%2Cs0%3B%3Bbandpass%3B%2Cc0%3B%3BBandpass%3B%2Cc0%3B%3BBANDPASS%3B%2Cc0%3B.t4%3B%2Cband%20-%20pass%3B%2Cc0%3B%2Cs0%3B%3Bband%20-%20pass%3B%2Cc0%3B%3BBand%20-%20pass%3B%2Cc0%3B%3BBand%20-%20Pass%3B%2Cc0%3B%3BBAND%20-%20PASS%3B%2Cc0

https://books.google.com/ngrams/interactive_chart?content=passband%2C+pass+band&case_insensitive=on&year_start=1920&year_end=2008&corpus=15&smoothing=3&share=&direct_url=t4%3B%2Cpassband%3B%2Cc0%3B%2Cs0%3B%3Bpassband%3B%2Cc0%3B%3BPassband%3B%2Cc0%3B.t4%3B%2Cpass%20band%3B%2Cc0%3B%2Cs0%3B%3Bpass%20band%3B%2Cc0%3B%3BPass%20band%3B%2Cc0%3B%3BPass%20Band%3B%2Cc0%3B%3BPASS%20BAND%3B%2Cc0

I’m a little old-fashioned and will stick with “bypass capacitor”, but prefer “bandpass” and “passband”.

The tool is not always useful—I can follow the rise and decline of “mho”, but “siemens” has too many other uses to be able to determine when the standard name for the unit of conductivity overtook “mho”. It is rather a shame that “mho” did not become the standard, as it is “ohm” backwards and ℧ is such a cute symbol (being Ω upside down).  I am sticking with the standard in my book, though.

(Sigh, the iframes that had the interactive graphics worked fine in the WordPress.com editor, but when the post was published, WordPress stripped them out, leaving only the links.  You’ll have to click through to see the graphics—sorry about that.)

History of electronics via Google ngrams

Filed under: Uncategorized — gasstationwithoutpumps @ 22:16
Tags: , , ,

I was playing with Google ngrams today (checking to see the whether some variant spellings were ever mainstream) and came up with a history of electronics in one graph:

A short history of electronics in a few key words. At first, power is what mattered, and voltmeters and ammeters ruled. In the 40s, time-varying signals mattered, and oscilloscopes started getting attention. Time-varying signals ruled until digital electronics took over with the introduction of the microprocessor. Now all these low-level views are losing space to consumer-level gadgets like mobile phones.

I could have picked different words, but because Google ngrams provides no way to switch to a log scale for the y-axis (the only sensible way to show growth or decay of word usage), it is not feasible to put a common word like “computer” on the same graph as a rare word like “multimeter”. Google, as always, provides an almost-reasonable product, then never takes the trouble to finish it to allow the user to do things right. Oh, well, it’s free, and that’s the business model Google is relying on: ads on free (almost usable) stuff. The two things they do well are search and selling ads.

Power Searching with Google

Filed under: Uncategorized — gasstationwithoutpumps @ 14:58

A few months ago, I posted about Google running a search class, but I was too busy to actually do the search class when they ran it.  They think that it was successful enough that they are running it again 2012 Sep 24–Oct 10: Power Searching with Google – Inside Search.  I probably won’t have time this time around either, but I’ll sign up again, just on the off chance that I do have some spare time.

They’re also impressed enough with the platform they built for the course that they are offering it for others to use as an open-source tool called Course Builder.  Of course, they are not offering the computer resources needed to run Course builder, which is not intended to be run on your laptop—you need a data center (at least a web server) to run a MOOC.

They will probably sell you cloud computing capability to run Course Builder at some future date (if they can convince enough colleges and other MOOC wannabes to use it), but for now this is a subtle advertising venue for them: “It also contains instructions for using other Google products”.
