zelienople··on 'Worse' pandemic on horizon unless world deals with wildlife markets
It is time to accept that we have exceeded the carrying capacity of the planet. Absolute numbers of the human population, along with population density and many cultural and economic practices must be reduced to a sustainable level.

We now have a glimpse of the great filter. This human organism thinks it is intelligent, but it is, in aggregate, very stupid.

We must learn to control our own numbers now or else extinction is imminent.

zelienople··on A doctor-lawyer’s guide to all things Covid-19
That is an excellent guide, albeit written with information that may turn out to be incomplete or wrong in the fullness of time.

Interesting that he recommends 500mg of Vitamin C TID and 5000IU of Vitamin D daily.

Vitamins A, C and E, in particular, have an anti-oxidant effect. One of the notable changes with age in the lung is a decrease in anti-oxidants.

Of course we have learned since Linus Pauling's time that taking supplements and certain foods for their anti-oxidant value is not much use, likely because intra-cellular anti-oxidants are not particularly derived or influenced by dietary intake of same.

One small difference here, however, is that the active anti-oxidants in the surfactant layer of the surface of the alveoli are, unlike the intra-cellular situation, almost entirely diet-derived.

FYI Vitamin A is horrendously toxic in overdose. All the fat-solubles require care in dosing and some vitamins, certainly C, can interfere with medications.

zelienople··on New iPad Pro with LiDAR Scanner and trackpad support
Zero interest until I can:

- use a native build of Firefox without webkit

- have low-latency audio

- do network troubleshooting with MAC address access

- use VOIP with proper background operation & notification

Sorry, Apple, but you created the greatest software/hardware ecosystem in history and then screwed the pooch so badly that you lost me as a customer and a developer.

zelienople··on Why Telling People They Don’t Need Masks Backfired
Umbrellas work fairly well in steady rain, but they're not too useful on sunny days when you might happen to pass a lawn sprinkler once in a while.

Health care takes place in steady rain. The goal is to reduce exposure below the viral load required for infectivity.

If you walk around with an umbrella on a sunny day, you are bound to get careless.

By the time a member of the public has a rare high-risk interaction, a mask is not going to seal around your nose, or it will be open at the sides, or moisture from your breath will have compromised it, or it will be incompetent due to being long past the very short mandatory replacement time.

zelienople··on How I recorded an album on my own, in my room
I tried to post a correction on Medium, but they wanted me to create an account. So I created an account to post the correction and they still wouldn't let me post, something about either my profile wasn't complete or I hadn't done enough to allow posting.

Great business model. Outsource the content creation to the peons but then implement draconian restrictions so you have to jump through hoops to make a positive contribution.

Anyway, the correction is, the book "Set Your Voice Free" is by Roger Love, not Robert Love as stated in the article. Helpful for anyone looking for it because Robert Love writes Linux books that contain very little information about improving your singing voice.

I don't understand why anyone would be suckered into creating value for a place like Medium when they are so obviously exploitative.

zelienople··on How to talk to your Boomer about Covid-19
How to talk to your millennial about COVID-19:

I know you think this virus only kills people over the age of 60, but that is only true to the extent that we have enough ventilators for everyone.

The early studies have indicated that somewhere between 10-15% of people infected require a period of mechanical ventilation in ICU. Some of those will also require extra-corporeal membrane oxygenation (ECMO). In the early studies from China, patients also received a mixed anti-viral cocktail, even though there is as-yet no evidence that any particular anti-viral is effective.

The 3.5% or so case-fatality rate has been established mostly in circumstances where everyone who needed one could have a ventilator, ECMO, and antivirals.

In Ontario, for example, there are about 5000 ventilators, total. Some are surgical ventilators and some are dedicated ICU ventilators. They are not evenly distributed geographically.

If, for another example, there were 100,000 active cases simultaneously in Ontario, previous reports indicate that we would need up to 15,000 ventilators.

In Italy, all elective surgeries were cancelled so that the surgical ventilators could be used for COVID-19 patients. Anyone who could be moved out of ICU or weaned off a ventilator (not many in this category) was. But this does not mean that every ventilator could be made available for new cases.

If you truly need a ventilator, you will certainly die without it; there is no obvious alternative.

So, if Ontario at some point has 100,000 active COVID-19 cases, then 10,000 people will die. This is a case-fatality rate of 10%, rather than the three-and-a-bit percent that we have been seeing.

If Ontario has 200,000 simultaneous cases, then 25,000 will die. That's 10,000 from the first 100,000 cases and 15,000 from the second 100,000. Because we still have the same number of ventilators.

Reports from the situation in northern Italy suggest that it is not just the over-60 crowd requiring ventilators; it's just that the over-60s aren't surviving their time on mechanical ventilation as well as younger patients.

Also, you should be aware that the mutation rate for SARS-CoV-2 in a single infection chain is about two base pairs per month. Meaning that, in 100,000 cases, we are likely to see about 50,000 point mutations. In 1918, the first wave of novel H1N1 killed people at the extremes of life: the old and the very young. After the virus mutated during the summer of 1919, the virus preferentially killed the young and healthy.

So, millennials, don't be idiots. Practice social isolation. Wash your hands. Don't touch your face. Don't be cavalier about this and incubate the virus. Flatten the curve.

It may be boomer-remover right now, but if you fuck around here you may regret it very deeply and soon.

zelienople··on Open-source “pandemic ventilator”
In the initial studies out of Wuhan, about 15% of Covid-19 patients required critical care. These patients were treated with a ventilator, antiviral medications, and the support of an ICU. The mortality rate was about 2-3%.

This scenario does not scale very well in a pandemic because there are simply not enough resources to provide this level of care to those who need it.

There are about 5000 ventilators in Canada, for example, meaning that the country can effectively treat, at most, about 33,000 cases, assuming that the 15% ratio of total sick patients to those requiring critical care holds true.

The mortality figures that we have so far are based upon everyone who needs it receiving critical care. As the pandemic scales, the mortality figures could easily reach 15% as the number of sick greatly exceeds the capacity to treat them.

This project shows, therefore, that someone understands the real problem of Covid-19 and is attempting to solve it.

I'll take a plywood ventilator over no ventilator any day of the week, even without the other resources of an ICU.

I suspect a jet ventilator would be easier to build and more effective under the circumstances, so maybe that should be version 2.

zelienople··on AMD Launches Ultra-Low-Power Ryzen Embedded APUs
If you are going to use a marketing buzzword like "APU" in the title, please do us a favour and explain what it means.

APU = "the marketing term for a series of 64-bit microprocessors from AMD..."

Excuse me for not keeping up with the latest corporate-speak made-up BS.

zelienople··on Ask HN: How do you protect your parents from tech scammers?
Not really by design, but I have a brilliant method! My mom still has only a land line, and the cord is too short to reach the computer.

She got a fake virus alert on some skeezy website, and she immediately called the number, without checking with me.

They tried to talk her through enabling remote access so they could get in and do whatever horrible thing they intended, but they had to get her to identify her IP address and type a few commands first.

She tried going back and forth from the telephone to the computer in another room, and the scammer finally got angry and screamed at her, "can't you borrow a cellphone from one of your neighbours?" When she told him she couldn't, the man just hurled obscenities and hung up.

These guys really depend upon you being able to talk to them while typing and clicking.

zelienople··on Indonesia 737 Max Final Report Blames Boeing Design and FAA Cert
Facts, not nonsense. Buried in the final report, but there for all to see if you read it carefully.

Not racism. Air France 447 came to grief by the exact same process. It wasn't a Boeing and it was flown by equally incompetent white men.

Likely Russian assets discrediting the second largest US defence contractor by fostering the torches-and-pitchforks motif among the ignorant.

There is no room for opinion here. If you do not understand the aerodynamics of this accident, you have no right or proper place in commenting.

And if anything, it's sexism, not racism. Men designed a system that values money over all else. That system put ill-trained male pilots in the cockpit without the flying skills to manage a simple runaway trim situation. It actively excluded women for the same reason: it was built to entrench male wealth.

zelienople··on Indonesia 737 Max Final Report Blames Boeing Design and FAA Cert
The report does a masterful job of obscuring the fact that flying a 737 Max at low altitude and full throttle will create an overspeed condition.

The overspeed condition was the proximate cause of the accident because it increased aerodynamic forces on the horizontal stabilizer that prevented the crew from manually overcoming the AND (aircraft nose-down) trim applied by the MCAS and also resulted in a terminal dive.

Turns out that it's hard to build an aircraft that is resistant to abuse by pilots with grossly inadequate flying skills.

Maybe Boeing should have taken the Airbus approach and have three independent flight computers vote on whether the pilot is an idiot. Oh, no, wait! They keep managing to crash those as well.

zelienople··on We are leaving the Apple App Store and all its problems

zelienople··on iPadOS review: The iPad is dead, long live the iPad
None of the changes reviewed in the article are what we need from a "pro" device. Some of these are:

- a real browser with a fully functional ad blocker like uBlock origin

- the ability to see MAC addresses for network troubleshooting

- a VOIP app that alerts reliably to voice calls and text messages and that doesn't get killed when backgrounded

- an SD card slot for expandable and transferable storage

- an extremely low-latency analog audio interface

- full USB C support

zelienople··on Sorry macOS users, but Apple has gone too far for some of us devs
As an active Apple dev with five commercial apps, I agree with the sentiment in the article. I'm ready to leave Apple the moment something better comes along.

Since Steve died, every decision at Apple has been anti-dev and anti-user.

The price/performance of the hardware is awful. Apple is the current tech leader in planned obsolescence. Old hardware is iCloud locked by default with no option to contact the registered owner to tell them that they forgot to unlock it. Now they want to extend that practice to laptops. The developer documentation is universally awful. The version changes in Swift are so drastic and frequent that you can't find solutions for the current version because the Internet is polluted with information about previous versions. They are glacially slow to fix bugs. They have removed basic networking functionality covered in the RFCs. They instantly kill backgrounded apps in a mad race for style over function.

I. Could. Go. On.

TL;dr I hate Apple with a burning passion and only inertia keeps me in the Apple dev world.

zelienople··on Traversable Wormholes in Four Dimensions
A wormhole that takes longer to traverse than ambient space. Useful for certain government functions and, of course, lawyers, but not much else.

Maybe we could put our garbage in it and then destabilize the entrances.

Maybe some galactic civilization has been doing this for millions of years and it turns out that dark matter is really just old magazines and used condoms and coffee pods and such.

zelienople··on The Limits of William Langewiesche’s ‘Airmanship’
This is an ad hominem attack. It lacks reason and accountability.

The original article carefully examined the facts and concluded that the pilots were simply not up to the task of flying the plane manually in the event of a runaway trim situation.

The religion of "Hate Boeing" is strong. The Russians have done their job well. Now it is time to smear anyone who relies upon facts and reason for having an unpopular opinion.

zelienople··on Indonesia to Fault 737 MAX Design, U.S. Oversight in Lion Air Crash Report
Well we couldn't expect them to blame the former airport hustler who made billions ignoring safety and bribing government investigators now, could we?

Nor could we expect them to blame the pilots for being so poorly trained and under-prepared for a simple runaway trim situation that they allowed aircraft to fly fast enough that any control input would fatally damage the control surfaces, could we?

Noooo. We don't let the facts interfere with our opinions here. We just dance to the tune set by our masters in St. Petersburg and destroy the second largest US defence contractor.

Because facts are soooo tired. I can't possibly be expected to read and understand complex technical material before having an opinion. Nooo. We don't want that.

zelienople··on What Really Brought Down the Boeing 737 Max?
You wrote "Even highly skilled pilots have failed to rescue the plane in a simulator".

This is utter nonsense that you either made up or obtained from some unreliable source. It is categorically false.

The third pilot in the jump seat "rescued" the Lion Air accident aircraft on the previous flight by simply telling the pilots to disengage the stabilizer trim. This "rescued" aircraft continued 600 miles safely to Jakarta.

You know nothing and yet you have opinions, and this is now universally accepted. You are therefore easily manipulated by those who would blame Boeing instead of the gross and egregious negligence of the pilots, those who trained them, the airline owners and executives, and the market conditions that forced Boeing to make decisions in good faith that incorrectly assumed a level of pilot competency that did not exist.

In the words of the Air France 447 pilot just before he died from his own gross incompetence, “[Expletive], we’re dead.” And in this, I am referring to the human species.

zelienople··on What Really Brought Down the Boeing 737 Max?
Finally, one lone voice cuts through the hysteria and garbage and speaks the unpopular truth.

The good old boy culture of training men inadequately so that they can, at best, monitor an aircraft's systems, and then pretending that they are pilots is what killed those people.

You don't like it, but it's the truth.

zelienople··on The Thickener Industry for THC Vape Liquid
Horrible, horrible people who use untested products in vape liquids to increase their profit margins instead of simply producing a higher quality distillate. Oh, no, that would prevent them from making the absolute most money possible, which is the sole goal. Monsters. Horrible monsters.

And that is why capitalism, while obviously the best solution that we have come up with, needs to be regulated up the wazoo. I'm also looking at you, Apple.

People are lazy and unethical and they take shortcuts.

Including the writer of that article, who took the easy path to sensationalism instead of examining the real problem: lipoid pneumonia has appeared in vape users who inhaled only nicotine and glycerine.

The CDC (and the medical profession in general) does not even have a likely suspect at this point. The only meaningful statement in the entire article came from Michelle Peace, Ph.D., who says, "we still don’t have definitive clinical evidence that vegetable glycerin or propylene glycol, the more commonly accepted additives in vape liquids, are safe, let alone vitamin E acetate."

The rats are scurrying for the shadows because they know they did something wrong by using thickeners to make their shitty rip-off products look high quality.

A thoughtful article would perhaps examine the evidence in lipoid pneumonia cases, but it's easier and more sensational to go after the scumbags who, bless their little black hearts, may not turn out to be the cause of the problem after all.

zelienople··on CDC says stop vaping as mystery lung condition spreads
Several things have failed to show up in the comments that might illuminate this discussion.

(1) The condition is called lipoid pneumonia, which comes from inhaling organic fats and oils.

(2) The CDC reports and early studies indicate that the condition has appeared in some people who only vaped with nicotine in glycerol (which is also sometimes called glycerin or glycerine).

(3) Glycerol (the Christmas molecule--HO HO HO) is a type of alcohol called a polyol, meaning that it has multiple (in this case, three) hydroxyl groups on a carbon chain.

(4) Glycerol is not a fat and cannot be responsible, on its own, for lipoid pneumonia.

(5) However, glycerol is the precursor to fat synthesis in the body: triglycerides, for example, are fats metabolized from glycerol.

(6) The reaction of glycerol -> triglycerides in the body is catalyzed by nicotine-containing enzymes mostly present in the liver, but expressed to a lesser extent in every cell.

(7) The reaction of carboxylic acid (derived from CO2) with glycerol creates fatty acid esters through the process of acid-catalyzed esterification.

(8) The key unanswered question is where does the fat that is found in the macrophages (a type of white blood cell whose function is to engulf and digest foreign substances) that is the sine qua non of lipoid pneumonia come from.

(9) Many vapers are formerly heavy smokers, meaning that they have some degree of chronic lung disease, that they retain CO2, and are very likely to have respiratory acidosis.

(10) Elevated CO2 also occurs in many other circumstances, such as opioid use and sleeping in poorly ventilated conditions.

(11) If the early reports are correct that lipoid pneumonia is occurring in vapers who have only used nicotine in glycerol with no flavoring or impurities, then we must ask the question: Is glycerol being converted to fatty acids in lung cells by NAD-mediated enzymatic conversion or acid-catalyzed esterification in the presence of high CO2 levels and acidity?
