dnhz··on How to lower the price of plant-based meat
Hopefully with less food in this theoretical scenario because most people are overweight.
dnhz··on Parler CEO says he was fired by board
I wonder how much damage that disastrous interview with Kara Swisher did (for the site and for Matze). I have no sense of this.

dnhz··on No one knows how much the government can borrow
Kids are expensive, especially if going the private school route.
dnhz··on Overweight and healthy is a big fat lie, obesity study finds
Sort of riffing on this subject, since rikishi are nearly all Asian: Asians are more vulnerable to diabetes than people of other ethnicities. Health authorities have recommended screening Asians with a BMI above 23 for diabetes. BMI, of course, is purely a function of weight and height.

> limiting screening at BMI ≥25 kg/m2 would miss 36% of Asian Americans with newly diagnosed type 2 diabetes. In the same study, Araneta et al. (39) found that screening Asian Americans at a BMI cut point of ≥23.5 kg/m2 identified approximately 80% of those with undiagnosed type 2 diabetes. Among Japanese Americans, lowering the BMI screening cut point to ≥22.8 kg/m2 achieved 80% sensitivity.

dnhz··on Dropbox to cut 11% of its global workforce
I'm confused here. Someone shared with me a file via dropbox, xlsx, and right at the top of the sidebar where I can leave comments, there's a download button.
dnhz··on The Points Guy: A Man Who Turned Credit-Card Points into an Empire
Credit card churning, manufactured spending, and points accumulation. These activities remind me of cryptocurrency in that there's profit to be made among those who participate, but it's also wasteful of time and energy. Here, credit card reward maximization rewards the status-seeking aspect within us. There's the thrill of getting something valuable (business class tickets and luxury hotels) for seemingly nothing.

In some sense, it's just being a savvy consumer, but I'd feel better if there were some sort of carbon tax placed on air travel.

dnhz··on Why Is There a Bucatini Shortage in America?
Barilla sells for $1.25 to $1.50 for 454 grams (1 lb) in the US; that's getting close to $2 per lb. De Cecco is premium stuff here. I've seen $4 per lb, which is like $9 per kg.
dnhz··on Fuzzy logic rice cookers (2016)
But presumably the GP isn't keeping the rice cooker on keep warm for days. All the moisture would be lost. Safer to refrigerate cooked rice.
dnhz··on Ultra-processed foods and the corporate capture of nutrition
That's empirically not true. Yeast do just fine with the starches in the flour. Here's a simple recipe without sugar (and the oil is optional too): http://www.thebreadkitchen.com/recipes/simple-whole-wheat-br...
dnhz··on U.S. Treasury breached by hackers backed by foreign government – sources
To sound geopolitically sophisticated. To pretend at the language of statecraft.
dnhz··on No, DeepMind has not solved protein folding
Well the other way to think about the problem is that protein structure can be robust to sequence changes. Among natural proteins, proteins that look similar can differ up to about 70% in sequence identity (since evolution had a hand in making sure the structure stayed folded as the sequence diverged from its ancestor). So long as some critical members of the sequence are preserved, the protein folds roughly to the same structure. AlphaFold does take advantage of this since part of the algorithm looks for sequence alignments with known proteins.
dnhz··on No one who got Moderna's vaccine in trial developed severe Covid-19
Viruses! RNA viruses like SARS-cov-2. They make the cell reverse transcribe their RNA cargo into DNA, and then the cell produces more viruses.
dnhz··on Lufthansa trialing lie-flat Economy seat concept
For $260, you can experience what it would be like to sleep on a park bench while 36,000 feet in the air.
dnhz··on Xi Jinping personally halted Ant's IPO after Jack Ma snubbed government leaders
I'm not a fan of cultural explanations for behavior versus realpolitik, especially when the alleged cultural characteristic can be distilled into a single phrase.
dnhz··on macOS unable to open any non-Apple application
I'm on Mojave and had problems.
dnhz··on No country on Earth is taking the 2 degree climate target seriously
Is there such thing as good/bad without consideration of the living beings on earth? It's life on the planet that matters, not the planet itself. "Good thing for the planet." How so?

It seems unlikely to me that the results of climate change will be so dramatic as to kill 80% of all humans, unless climate change sparks some sort of global war involving nuclear weapons. That doesn't sound very good for the planet.

dnhz··on Times Change: Inside the New York Times’ Heated Reckoning With Itself
Sounds quite messy in the slack channels of the nytimes. A democratic (small D) atmosphere where the newspaper’s hierarchy does not seem to matter. Interesting that the tech and data workers of the times feel as justified in opining on the paper’s direction as the writers and editors. This article makes it sound as if the insurrection from within is driven partly by those who are not producing the main content of the paper.

I was surprised to read that the opinion section garners 20% of the reads despite being 10% of the content. I personally avoid the opinion section because it feels impotent; the republicans control the government and indignant opinions change nothing about that.

What!?! The study was wrong? checks google wow just hearing about it today.
dnhz··on Biden wins White House, vowing new direction for divided U.S.
Where does 12 years come from? Obama served more years in federal government as a senator than did Bush or Clinton (former state governors).
dnhz··on Playstation 5 review: Not just a more-powerful PS4
Counter strike has HRTF. It’s nice.
dnhz··on There was a clear winner on election night: Marijuana
The original point is that no amount of smoking or drinking is good for you. Sugar has a threshold since fruit is healthy.

Sugar gets all the blame, and fat is ignored even though consumption of both have increased (in the US) over time. And fat is confusing to people because nowadays plenty of people believe saturated fat is ok. I'd support a soda tax though.

dnhz··on There was a clear winner on election night: Marijuana
Carcinogens: smoke, alcohol.

Not a carcinogen: sugar.

Sugar demonization is out of control. Many people eat an unhealthy amount of it, but any level of tobacco or alcohol consumption harms health.

dnhz··on House Hunting in France: A Once-in-a-Millennium Castle for $3.3M
I saw this tweet earlier: https://twitter.com/JohnArnoldFndtn/status/13168156814307164...
dnhz··on Reading too much political news is bad for your well-being
Written news and commentary (mainly online) is not that different. When Trump caught covid, there were endless articles speculating about how severe his illness was or whether a second week with the virus would bring about more severe symptoms. Just a bunch of suppositions and hypotheticals to get you to click and spend a few minutes reading.

The main loss from all this is not wasted time but that serious issues receive less discussion in favor of what's happening right now and what it could possibly mean.

dnhz··on Car seats as contraception
What about paying to send three kids to college at about the same time versus two? Couldn't that be as big a consideration as the physical limits for fitting car seats into a car?
dnhz··on Ask HN: Is hydrogen likely to be a major source of power in the next 10 years?
That's not that bad right? 15 gallons of gas could be 43 kg, and the gasoline fuel tank has some weight too.

Although, after google search, I see that the Mirai weight is 4075 lb, and the Prius weighs around 3100 lb.

dnhz··on Ask HN: Is hydrogen likely to be a major source of power in the next 10 years?
General aviation fuel is leaded but jet fuel does not contain lead.
dnhz··on Supercomputer analysis of Covid-19 leads to new theory
The description of RNA-seq analysis spans nearly the entire paragraph, by my interpretation and limited understanding of the methods.

> RNA-Seq analysis was performed using the latest version of the human transcriptome (GRCh38_latest_rna.fna, 160,062 transcripts to which we appended the SARS-CoV-2 reference genome, MN908947). Mapping parameters were set with a mismatch cost of two, insertion and deletion cost of three, and both length and similarity fraction were set to 0.985. TPMs were generated for all 160,063 transcripts for the nine COVID-19 samples and the 40 controls (Supplementary file 2). The resulting transcript mappings for genes of interest were manually inspected to account for any expression artifacts, such as reads mapping solely to repetitive elements such as the Alu transposable element or all reads mapping to a UTR or pseudogene therein. Transcripts whose counts came solely from (or were dominated by) reads at repetitive elements were removed from the analysis. For the controls cases we ran an outlier analysis using the prcomp function in the R package factoextra. Input data were TPM for transcripts that averaged greater than one across all samples (30,102, Supplementary file 2).

dnhz··on Transit Costs Project
What do you mean? What would give foreign companies an advantage? If a transit construction project can be done at lower cost, isn't that a good thing, for the local government and for riders? And construction is something that hires local workers anyway.
dnhz··on Transit Costs Project
This Dec 2017 nytimes article is a relevant read: https://www.nytimes.com/2017/12/28/nyregion/new-york-subway-...

> France’s unions are powerful, but Mr. Probst said they did not control project staffing. Isabelle Brochard of RATP, a state-owned company that operates the Paris Metro and is coordinating the Line 14 project, estimated there were 200 total workers on the job, each earning $60 per hour. The Second Avenue subway project employed about 700 workers, many making double that (although that included health insurance).

It seems like transit bureaucracies in the US don't have the expertise to manage massive construction projects and little incentive to control costs.

I was unable to browse the link because the site is overloaded, but I'm familiar with Alon Levy and his blog. Hopefully the data makes a difference but bureaucrats often to respond that their situation is unique and not comparable to other countries.
