calebsurfs··on Spreadsheet of San Francisco Bay Area Covid-19 Data and Charts
To me the hospitalization rate is most important.

* Overcrowded hospitals is what leads to large jumps in fatality rates.

* It only lags the date of infection by about a week.

* It also isn't subject to external factors like availability of tests. (Though availability of hospital beds is a factor later on)

calebsurfs··on Are patients with hypertension and diabetes at increased risk for COVID-19?
The active dose is nowhere near the lethal dose. It is however close to the dose where you could see some minor damage to the liver. It causes problems because people are addicted to opioid drugs that are typically combined with acetaminophen, not because they are loading up on acetaminophen itself.
calebsurfs··on Typhoon Lands in Japan – Windy Storm-Tracking Platform
Windy has cool graphics, but it's only forecasted winds and not very granular. If you want to see actual wind observations from satellites check out ASCAT here[0] or here[1]

Any suggestions for a _quiet_ bean grinder that won't disrupt a small office with its noise?
calebsurfs··on Ocean Warming Is Accelerating Faster Than Thought, New Research Finds
Sea level rise has regional variation due to the gravitational pull of the melting ice. When polar ice melts, there is less gravity at the poles so equatorial regions see higher sea level rise.

calebsurfs··on Rising Waters Are Drowning Amtrak's Northeast Corridor
This is nothing compared to the estimated $3.5 billion to redirect the tracks underground in San Diego. Coastal bluff failures are occurring within several feet of the tracks on a regular basis. I spend time at this beach and I don't know how this track will be viable in a couple years, with or without rising sea levels. Once it is deemed unsafe, San Diego will be completely cut off by rail.

calebsurfs··on The High Stakes of Surfing’s Wave-Pool Arms Race
A glaring omission from this article is mention of the surfer who died from a brain eating bacteria [0] after visiting the pool in Waco.

The wave pool there is classified as a 'lake' so normal rules for chlorination and filtration don't apply.

calebsurfs··on Ask HN: What discontinued company/product do you wish was still around?
Try selecting "Verbatim" in the tools menu - it can really improve your google search on technical topics.
calebsurfs··on Aeolus preparing to fly the wind mission
This looks a lot more sophisticated than currently operating satellite wind mapping, which uses radar deflection off water to estimate wind speed and direction. I hope they make data as easily available as noaa:

calebsurfs··on On its 100th anniversary, the madness of Daylight Saving Time endures
Or we could just get rid of daylight savings so we wouldn't have to complain anymore.
calebsurfs··on IV Bags May Not Be Necessary to Rehydrate Patients
There is a major difference between Gatorade and Powerade, which is the type of sugar.

Gatorade has glucose (aka dextrose, the same sugar as an IV bag) while Powerade has high fructose corn syrup.

Glucose can be used directly by your cells while fructose is metabolized in the liver first. So for quick relief from dehydration I choose Gatorade.

* Glucose = 100% dextrose

* table sugar / sucrose = 50% dextrose

* high fructose corn syrup = ~40% dextrose

calebsurfs··on Leisure Luxuries and the Labor Supply of Young Men [pdf]
Those are relevant facts but they leave out immigrants who are leaving voluntarily. I couldn't find anything within the last 6 months but there was recently a net outflow of undocumented immigrants [0]

calebsurfs··on Leisure Luxuries and the Labor Supply of Young Men [pdf]
My observation is that teens are taking jobs that were previously done by undocumented immigrants who have left due to the current political climate. I expect immigration policy could be more closely correlated with young men's labor than video games.
calebsurfs··on ‘Instantly rechargeable’ battery could change the future of electric automobiles
What is the energy density of a flow battery like this? It's hard to imagine it is anywhere near gasoline or a lithium ion battery.
calebsurfs··on Ask HN: Projects that don't make you money but you're doing it out of sheer joy?
I need coastal weather data to find the best waves for surfing so I built http://www.swellmatrix.com

I would start other projects with money- making potential but there are always features to add to the site that can get me more waves...

calebsurfs··on Ask HN: Who's running a profitable newsletter?
I'd really like something like this in podcast form. Summarize the best links and maybe invite some highly rated commenters on for discussion.
calebsurfs··on Introducing Surface Laptop
When you get a chromebook you can redeem an offer for 100gb free for 2 years. When your 2 years is up, files aren't deleted but you can't upload anything else until you're below the 15gb. Drive is always free up to 15gb.
calebsurfs··on The Nightmare Scenario for Florida’s Coastal Homeowners
California isn't an area where sea level will go down, ironically it will go down near Greenland and Antarctica due to less gravity from ice sheets. There are some nice maps towards the bottom of this article:

http://onlinelibrary.wiley.com/doi/10.1029/2012GL053000/full

Since Florida is near the equator, facing the same ocean as Greenland, and has subsiding land, it will likely experience more effects of sea level rise.

calebsurfs··on GoPro Camera Maker Cuts Jobs Again in Search of Profit
I would love an indestructible GoPro branded smartphone with a long lasting battery and good camera. Am I the only one?
calebsurfs··on Poet: I can’t answer questions on Texas standardized tests about my own poems
Interesting, your point makes sense.

I agree with the author that the poems selected, and the questions about them, are awful. I also got a perfect score in a reading standardized test (ACT) many years ago but I had no idea how to answer the questions in the article.

calebsurfs··on Poet: I can’t answer questions on Texas standardized tests about my own poems
The problem isn't that the author doesn't know the answers, it's that the test is looking for 1 correct answer. The point of reading and analyzing poetry is in the process and being able to explain your reasoning coherently.
calebsurfs··on Why anything? Why this? (1998)
Part 2 is here, with plenty of food for thought:

http://www.lrb.co.uk/v20/n03/derek-parfit/why-anything-why-t...

> If we find this astonishing, we are assuming that these features should be the Selectors: that reality should be as simple and unarbitrary as it could be. That assumption has, I believe, great plausibility. But, just as the simplest cosmic possibility is that nothing ever exists, the simplest explanatory possibility is that there is no Selector. So we should not expect simplicity at both the factual and explanatory levels. If there is no Selector, we should not expect that there would also be no Universe. That would be an extreme coincidence.

calebsurfs··on Raspberry Pi releases an OS to breathe new life into old PCs
I'm surprised they ship with chromium, I have had a much better experience with firefox than Chrome on my low end laptop.

Does chromium have a smaller memory footprint than Chrome?

calebsurfs··on The Distribution of Users’ Computer Skills: Worse Than You Think
You can take the technology part of the test here:

I have to admit I found it somewhat difficult, it's not surprising that most people performed poorly on it.

calebsurfs··on Show HN: Swell Matrix: real-time ocean wave data
With large surf hitting the coast of California I thought it would be a good time to show my personal project. It is a visualization of wave buoy spectral and time series data, plus marine weather for surfers and boaters.

Comments and suggestions are appreciated!

calebsurfs··on How Ancient Humans Reached Remote South Pacific Islands
The ability to sail a boat up wind. The boats they used, catamarans, have a hard time sailing less than 90 degrees to the wind even today.
calebsurfs··on Free for students: Professional developer tools from JetBrains
I've been using pyCharm for the last 2 years and its code completion has helped me code and learn at a much faster pace than other editors.

It offers code suggestions for any module that has been imported in addition to everything in the current script. Sublime and vim's code completion seem very primitive in comparison.

That said, I usually use the free Community Edition because it loads faster.

calebsurfs··on Two years spent spamming spammers back
Locals usually have a way to get rid of street vendors that is effective, so finding out what that is in your locality is a good idea.

In Mexico, it's Hoy no (Not today) and it works pretty well.

calebsurfs··on Show HN: An interactive comparison of 256 popular monitors
I like this

One feature I would like is the ability to plot multiple axes via bubble plots- categorical data could be shown with colors and quantitative data with circle size. That way I could sort out monitors by price, size and response time for example.

calebsurfs··on Ask HN: What is the evolutionary explanation for having a song stuck in my head?
Long-distance running on the savanna exerted many selective pressures on early humans.

Hearing rhythmic sounds in your head could arise from prehistoric humans running in groups together- music / songs on repeat helps synchronize pace and maintain tight formation.
