If You Fall Through Thin Ice

| Comments

Another item to file under useless information that just might one day save your life. Kenton Whitman explains how to survive a fall through ice on a frozen lake or river.

While it varies with water temperature and body mass, it can take 30 minutes or more for most adults to become even mildly hypothermic in ice water. Knowing this is vitally important in a survival situation, since people would be far less likely to panic if they knew that hypothermia would not occur quickly and that they have some time to make good decisions and actions to save themselves.

In other words - keep calm and kick your way out.

Northern Lights Photographer of the Year for 2020

| Comments

Maze’s photo, of the aurora australis in Tasmania, is stunning — one of the best astronomy photos I have ever seen. Here’s how he captured it:

Captured in this image is a trifecta of astronomical phenomena that made for some of the best astrophotography conditions one can witness in Australia, namely, the setting Milky Way galactic core, zodiacal light, and of course, the elusive Aurora Australis. On top of this, a sparkling display of oceanic bioluminescence adorned the crashing waves, adding the cherry on top to what was already a breathtaking experience.

Having been out of reception and civilization for over a day, fellow photographer Luke Tscharke and I had no idea the aurora would strike on this night. We’d just heard rumors of a potential solar storm. We could barely contain our excitement when the lights first showed up on our camera’s screens. We later realized we were in the best place on the entire continent to witness the rare show, with Lion Rock being on the southernmost cape of Tasmania and much more cloud-free than the rest of the state at the time.

The colors that our cameras picked up were incredible, too. Rather than the classic green, the display ranged from yellow and orange to pink and purple. When I’d captured enough frames that I was happy with, I simply stood by my camera with my head tilted towards the sky, occasionally swirling my hand around in the sparkling water by my feet. I’m forever grateful for moments in nature like this that show us the true wonders of our planet.

Apple Search Engine

| Comments

Looks like Apple is seriously ramping up its search bot activity. This looks like a direct result of U.K. competition commission threat to break up the Google/Apple agreement to be the default search engine on iOS devices.

But does Apple really have a chance of disrupting Google at its own game? FastCompany’s Hamza Mudassir:

Apple’s search engine will have a different future if rumors about its business model are true. Apple has been focusing heavily on user privacy recently, including but not limited to publicly refusing to give secret access to its devices to the FBI. It will be very much in line with this “privacy first” position that Apple chooses not to make money from advertising, which involves exposing customer usage data to third parties. Instead, it could simply sell more of its highly profitable devices and subscriptions to privacy-conscious customers. By not following Google’s footsteps, Apple does not have to engage with the search giant on its terms.

Why Apple Will Disrupt the CPU Industry

| Comments

In his excellent piece on Why Is Apple’s M1 Chip So Fast?, Erik Engheim summarizes Apple’s greatest advantage in the upcoming CPU wars.

Here we get a big problem with the Intel and AMD business model. Their business models are based on selling general-purpose CPUs, which people just slot onto a large PC motherboard. Thus computer-makers can simply buy motherboards, memory, CPUs, and graphics cards from different vendors and integrate them into one solution.

But we are quickly moving away from that world. In the new SoC world, you don’t assemble physical components from different vendors. Instead, you assemble IP (intellectual property) from different vendors. You buy the design for graphics cards, CPUs, modems, IO controllers, and other things from different vendors and use that to design an SoC in-house. Then you get a foundry to manufacture this.

Now you got a big problem, because neither Intel, AMD, or Nvidia are going to license their intellectual property to Dell or HP for them to make an SoC for their machines.


For Apple this is simple. They control the whole widget. They give you, for example, the Core ML library for developers to write machine learning stuff. Whether Core ML runs on Apple’s CPU or the Neural Engine is an implementation detail developers don’t have to care about.

Buckle in - we are in for a very interesting 2021!

Did You Not Know Who This Man Was?

| Comments

Jake Tapper has a question for the GOP:

And more importantly, tragically, unacceptably, horrifyingly even putting lives at risk - it has to be asked. Did you not know who this man was when you took him in?

The horrifying truth is that they did know. The GOP decided to put their self interest, their pursuit of power and their party before the United States and their constituents. This administration and the members of the GOP have put the final nail into the coffin of “The Party of Lincoln”.

Limitations of IBIS

| Comments

IBIS is one of the most useful advancements in digital photography. Olympus arguably had the most sophisticated implementation for its Micro Four Thirds system - which supported an amazing 6.3 stops! Which begs the question just how far can this technology go?

Olympus claimed that 6.3 stops was the theoretical limit due to the earth’s rotation, not the electronics. David Berryrieser in at The Center Column has a detailed mathematical explanation. Here is a summary for those who are terrified of a little math :)

To illustrate , lets imagine that you are somewhere on the Earth’s surface, pointing the camera due East or West. For simplicity, lets assume you are on the equator, but your latitude doesn’t actually matter for this analysis. There are 86,400 seconds in a day, so Earth rotates at a rate of 2π/86400 radians/second, or 7.27*10^-5 rad/s. That means that your subject, which is presumably stationary on Earth’s surface as well, is rotating at this rate. Your camera, which is using its IBIS system to attempt to keep everything as still as possible, may not realize that you are rotating with your subject and will instead try to zero out any rotation of the camera, including that of the Earth. More technically, the camera is trying to maintain stability with respect to an inertial reference frame, which by virtue of the Earth’s rotation, you and your subject are not.

Lets face it though, nothing will beat good technique and a tripod!

When States Do Nothing

| Comments

The story of the coronavirus in this state is one of government inaction in the name of freedom and personal responsibility. Iowa Governor Kim Reynolds has followed President Donald Trump’s lead in downplaying the virus’s seriousness. She never imposed a full stay-at-home order for the state and allowed bars and restaurants to open much earlier than in other places. She imposed a mask mandate for the first time this month—one that health-care professionals consider comically ineffectual—and has questioned the science behind wearing masks at all. Through the month of November, Iowa vacillated between 1,700 and 5,500 cases every day. This week, the state’s test-positivity rate reached 50 percent. Iowa is what happens when a government does basically nothing to stop the spread of a deadly virus.


[Iowa Governor Kim Reynolds] did not require Iowans to wear a mask in public, ignoring requests from local public-health officials and the White House Coronavirus Task Force and arguing that the state shouldn’t make that choice for its people. “The more information that we give them, then personally they can make the decision to wear a mask or not,” Reynolds said in June. She also wouldn’t require face coverings in public schools, where she ordered that students spend at least 50 percent of their instructional time in classrooms. When Iowa City and other towns began to issue their own mask requirements, Reynolds countered that they were not enforceable, undermining their authority.

All we need to do as a society is to achieve 95% mask usage and the pandemic would be controlled and life can began to return to normal. This is isn’t wishful thinking. Just look to South Korea as an example. South Korea has a total of 35,703 cases with 529 deaths as of this writing - the United States has 13,999,385 cases with 273,518 deaths.

Wear a damn mask.

Apple is about to disrupt the microprocessor industry. The M1 chip is as industry shaking as the iPhone.

John Grubber at Daring Fireball sums it up perfectly:

M1 Macs embarrass all other PCs — all Intel-based Macs, including automobile-priced Mac Pros, and every single machine running Windows or Linux. Those machines are just standing around in their underwear now because the M1 stole all their pants. Well, that just doesn’t happen, your instincts tell you. One company, even a company like Apple, doesn’t just embarrass the entire rest of a highly-competitive longstanding industry. But just because something hasn’t happened — or hasn’t happened in a very long while — doesn’t mean it can’t happen. And in this case, it just happened.


For the industry as a whole, though, the M1 Macs have dropped as a bit of a shock. One reason for this, I think, is that Apple’s silicon prowess in iOS devices has been a slow boil. iPhones and iPads are better computers — faster and more efficient — than their Android competitors. But it’s been an annual incremental game. And it’s hard to tell what’s attributable to iOS’s software efficiency vs. Android and what’s attributable to Apple’s silicon prowess vs. Qualcomm and Samsung and whoever else is making chips for Android devices.

M1 Macs completely upend what we can and should expect from PCs. It’s a breakthrough along the lines of the iPhone itself in 2007.

The adage is, “If it sounds too good to be true, it probably is.” Emphasis on probably — the M1 Macs are an exception. They really are that good.

Intel x86 is the modern Zune. Believe the hype - lest you sound like this guy:

It's Time to Hibernate

Derek Thompson in The Atlantic

We’re also likely to see a historic increase in testing from all these people returning from their Thanksgiving vacation. On Sunday, the White House coronavirus-task-force coordinator, Deborah Birx, told CBS that everybody who traveled should “assume that you were exposed and you became infected.” That would mean tens of millions of people trying to get tested in the next week or so, leading to a backlog on top of the backlog.

In sum, the next few weeks are going to be a statistical blur at the very moment when families are looking for clarity regarding the winter holidays. As COVID-19 hospitalizations reach an all-time high, we are facing a normal weekend testing delay, exacerbated by a major holiday, complicated by the already rising COVID-19 caseload, and further burdened by the imminent wave of tests that will be demanded by people coming back from their Thanksgiving trip. For that reason, state and local governments, businesses, and families might have to fly blind for a while in the fog of pandemic.

The safe assumption is that cases, hospitalizations, and deaths will all reach new highs before Christmas. The virus is simply everywhere. While the spring wave slammed into the Northeast and the summer surge swept over the South, the latest surge, while concentrated in the Midwest, is truly national. Almost every state has seen an increase in cases since September, and nearly 40 states saw COVID-19 hospitalizations reach record highs in the past three weeks. Right when Americans should have separated themselves from new exposures, millions of them shuffled and reshuffled themselves into new combinations of people. This epidemiological experiment seems destined to produce more deaths, more grieving, more illness, and more exhausted health-care workers, who were already on a “catastrophic path” before 9 million people filed through TSA checkpoints in the past week.

Seriously? What the hell is wrong with people? Buckle up - we are headed for the worst public health catastrophe in US history. Stay home. Hibernate.

Scott Atlas Did More Damage Than You Can Imagine

Why do they keeping paying respect to Atlas by referring to him as a doctor? He has clearly shown that he has violated a doctor’s primary oath - do no harm. Scott Atlas should have his license revoked. At the very least stop giving him professional respect.

Apple's Chief Security Officer Indicted

| Comments

A grand jury issued two indictments ​on Thursday, Nov. 19, against Undersheriff Rick Sung, 48, and Capt. James Jensen, 43, who are accused of requesting bribes for concealed firearms licenses, also known as CCW licenses. Insurance broker Harpreet Chadha, 49, and Apple’s Chief Security Officer Thomas Moyer, 50, are accused of offering bribes to receive the permits, District Attorney Jeff Rosen said during a press conference on Monday morning.

The two-year investigation by the district attorney’s office found that Sung, who was allegedly aided by Jensen in one instance, held up the distribution of CCW licenses and refused to release them until the applicants gave something of value. […]

Sung and Jensen allegedly held up four gun licenses from Apple employees and extracted from Moyer a promise that Apple would donate iPads to the sheriff’s office. A donation of 200 iPads worth nearly $70,000 was ended at the last minute after Aug. 2, 2019, when Sung and Moyer learned that the district attorney’s office had issued a search warrant seizing all of the sheriff’s office’s CCW license records.

Can’t understand this obsession with carrying firearms…

Swiss Cheese Covid-19 Defense

| Comments

Virologist Dr. Ian Mackay has visualized the Swiss cheese Covid-19 defense in a wonderful way (pictured above). Each layer of cheese represents a personal or shared intervention — like mask wearing, limiting your time indoors w/ crowds, proper ventilation, quarantine, vaccines — and the holes are imperfections. Applied together, these imperfect measures work like a filter and can vastly improve chances of success. He even added a “misinformation mouse” chewing through one of the cheese slices to represent how deceptive information can weaken these defenses.

We Don't Need to Meet Nazis Halfway

| Comments

Supreme Court Justice Samuel Alito just complained that “you can’t say that marriage is a union between one man and one woman. Now it’s considered bigotry.” This is a standard complaint of the right: the real victim is the racist who has been called a racist, not the victim of his racism, the real oppression is to be impeded in your freedom to oppress. And of course Alito is disingenuous; you can say that stuff against marriage equality (and he did). Then other people can call you a bigot, because they get to have opinions too, but in his scheme such dissent is intolerable, which is fun coming from a member of the party whose devotees wore “fuck your feelings” shirts at its rallies and popularized the term “snowflake.”

Nevertheless, we get this hopelessly naive version of centrism, of the idea that if we’re nicer to the other side there will be no other side, just one big happy family. This inanity is also applied to the questions of belief and fact and principle, with some muddled cocktail of moral relativism and therapists’ “everyone’s feelings are valid” applied to everything. But the truth is not some compromise halfway between the truth and the lie, the fact and the delusion, the scientists and the propagandists. And the ethical is not halfway between white supremacists and human rights activists, rapists and feminists, synagogue massacrists and Jews, xenophobes and immigrants, delusional transphobes and trans people. Who the hell wants unity with Nazis until and unless they stop being Nazis?

I'm Gonn Give You Facts...

Jordan Klepper on what hopefully is the last Trump rally of the 2020 campaign:

Tony, I need my sheet. I’m gonna give you facts. That fact sheet.

That fact sheet is in my car.

Trump supporter pulling out her cell phone to find those facts.

Okay, jobs added 4 million. Under Biden and Obama negative 2.8 million.

What is your website you are on?

I don’t know.

And what is going to happen if Trump doesn’t win the 2020 election? What are his bat shit crazy supporters going to do?

I will not live under a socialist government. Just look up the three red flags on the Biden campaign poster, there’s three red lines.


Look it up on Google.

Well I think it’s an E

Its supposed to be an E but look at the tree red flags or red banners.

And they mean?


He snuck communism right there on the flag?

You got it.

you don’t want to be in a place with socialized medicine?


So where would you go?

I am gonna look at Costa Rica.

Costa Rica? Which has universal health care?

Yea, I mean, I’m not gonna live under socialist rule. I don’t think Biden is gonna make the four years, and the camelback, forget it.

Camelback? Who’s that?


These people are so ignorant. Whats scary and disturbing is how they all revel in their ignorance. And ignorance would be bad enough - if not for their racism. Here is hoping that this is an anomaly in American political history. Seven More days to go…

Leave No Doubt

We are just over one week till the 2020 election (8 days, 11 hours, and 27 seconds of this writing). Regardless of where you stand on policy or what your political affiliation is, it is time to return to decency and intelligence in the White House. That doesn’t mean that we agree on everything, but it does mean that we can have a constructive, reasoned and intelligent conversation.

And just in case you forgot what that looks like:

So go out and vote. Leave no doubt.
