lowercase1··on Why is California wasting millions on hydrogen fuel pumps?
Trucks have a higher duty cycle than cars so a battery pays for itself quicker.

Truckers have legally mandated breaks that largely mitigates charging time.

Charging infrastructure is cheaper than hydrogen infrastructure.

lowercase1··on Five fold increase in Cardiac deaths of FIFA athletes
"To find out how many deaths actually occurred during the last two decades among FIFA players (2001-2020), we used Wikipedia - "List of association footballers who died while playing". To know how many cases occurred in 2021, we used the list collected by us in "Real-Time News" (which includes the cases noted in Wikipedia for 2021)."

There are cases that didn't make it to wikipedia (14 for 2021). The graph there is just not accurate to what is in Wikipedia e.g. more one listed in 2018.

https://en.m.wikipedia.org/wiki/List_of_association_football...

That said the cases are elevated in 2021

lowercase1··on Post-SSRI sexual dysfunction
Recreational doses are 10x-30x that of medical doses and those effects are quite a bit less at medical doses

lowercase1··on Always Do Extra
>And it's with this decision that every reasonably happy, veteran developer I know distinguishes themselves. They all choose Extra.

Selection without causality can explain this. Turns out people who survive either have personality or environment that enable them to feel the Extra work is worth it. Where I'm at, it certainly doesn't.

lowercase1··on Prometheus Fuels (YC W19) Closes Series B with $1.5B Valuation
Yeah the tech seems feasible but I'm skeptical of controlling capital costs when you need carbon nanotubes membranes as a core piece.

Air capture is also quite expensive and I'm not sure how much the "only need small concentrations of CO2" trick does.

lowercase1··on Google, Apple remove Navalny app from stores as Russian elections begin
Many of those shareholders are diversified and may benefit more from a freer Russia than they lose in short term google profits
lowercase1··on Cal Newport on an industrial revolution for office work
This seems good but falls apart with.long approval chains (which are maybe the core issue).

If I need library PR approved so I can make a service 1 PR so I can make a production release request so that I can deploy a one line change then it's hard to get things done with 4 hour ping time.

lowercase1··on Form Energy reveals the chemistry of its long-duration battery
Anyone can take a battery and just decrease the discharge rate and claim "long duration storage".

The hard part is making it cheaper per kWh.

If they made it cheaper per kWh then they should say that

lowercase1··on I had to give a wrong answer to get the job (2017)
Them: Please randomize a list in O(n) time.

Me: so you just want me to generate O(n lg n) bits of entropy in O(n) time? That's not possible.

lowercase1··on I Will Never Use a Microsoft Account to Log Into My Own PC
My username is "fucky" after I used an name to describe my feelings of having to create/use a Microsoft account. Exercise to the reader to guess the unshortened name
lowercase1··on Ford unveils Maverick, a compact hybrid pickup truck for under $20k
That's what qualifies as "compact" these days?
lowercase1··on Terraform 1.0
Yeah. I have a poor view of terraform since my first interaction was trying to a few one line changes to avoid repetition but couldn't find why it didn't work without setting up connection to the AWS S3 bucket.
lowercase1··on IEA exposes the hidden environmental costs and infeasibility of going green
IEA has consistently underestimated solar/wind deployment and cost improvements. Predicting minimal change each year even as prices drop and deployment soars. Should we really expect them to be accurate on the mineral limitations of batteries/solar/wind?

lowercase1··on A New Architecture for Plaid Link: Server-Driven UI with Directed Graphs
Thanks for the answers.

How is session state kept? Is /event required (as data would be sent in /next?).

Also as I understand, Processors won't be involved until they are needed. E.g. if we have 2 panes but only the result of the first was required to be processed, would the processor be invoked after just the first pane was complete?

lowercase1··on A New Architecture for Plaid Link: Server-Driven UI with Directed Graphs
Would be interested in:

1. How you implemented this on the backend? Did you consider using something like Temporal, AWS Simple Workflow, or AWS Step Functions?

2. Interested in how you're avoiding (waiting) on network calls on each action. You mentioned it was coming in next post.

3. How are you managing multiple workflows? Does a common child graph make sense for a common workflow?

lowercase1··on The compiler will optimize that away
The source of this capability is hidden in that you had to pass in a Foo to the call site.

If you had done similarly in the struct example by passing in the function Bar to the caller then you could achieve similar functionality by shoving in a Baz function instead.

lowercase1··on New Google Fi Cell plans – unlimited data for $30
Coverage is pretty good. It is great for traveling abroad as it just works in most countries.

However I'm looking to leave because Google's terrible handling of Hangouts which many used for SMS messaging. Hangouts also allowed phones calls on computers, a feature I will miss.

lowercase1··on JPG File Sells for $69M, as ‘NFT Mania’ Gathers Pace
It's bragging rights like owning a original painting when copies/replicas exist.

Real question is how mucg is preventing a second competing NFT from existing for the same item via and alternative design or chain or currency?

lowercase1··on What happens when investment firms acquire trailer parks
GP frames it wrong but building codes make make affordable housing very hard to create in ways unrelated to safety.

>most homes built in Des Moines will be required to have a full basement, a single-car garage, and a driveway. Minimum lot sizes for single-family houses will range from 7,500 to 10,000 square feet. Building codes meant to guarantee residents’ safety will now decree their comfort

lowercase1··on Did Schnorr destroy RSA? Show me the factors
An attack is anything that makes it take less than a brute force effort (of 2^80 operations). A 2^63 effort is really expensive in 2007. But by 2015 computation was maybe 2^5 times cheaper and there was a 2^5 cheaper attack.

I believe that this breakthrough could be quite a bit bigger because it's changing the costs from exponential to polynomial and so speedup is likely a much bigger change.

lowercase1··on Draw an iceberg and see how it would float in water
It's just potential energy minimization. A tall thin iceberg will float on its size in 2D or 3D.
lowercase1··on Effective Property-Based Testing
This is a good overview of property based testing but the mentions of Cucumber threw me off.

In my job Cucumber seems to add little more than just commenting and sequencing functions, tasks that are better suited to your programming language of choice, while adding overhead and complexity.

What am I missing?

lowercase1··on Select a muscle and it provides the exercises to workout the selected muscle
Do you have a sturdy table you could do a lateral row on? Maybe even just get a wood plank or bar and put it between two things?
lowercase1··on Photocatalyst splits water into H and O2 at quantum efficiency near 100%
75 kWh doesn't take a few hours with a supercharger. Doing similar with hydrogen is probably a similar level of infrastructure.
lowercase1··on Photocatalyst splits water into H and O2 at quantum efficiency near 100%
1. Hydrogen distribution might be able to use/share natural gas infrastructure (not high yield so embridlement isn't as big an issue)

2. Hydrogen is used for chemical processes (refining/ammonia) that can serve as a first step even if use for energy storage never becomes feasible.

3.Hydrogen is cheaper to store (<$10) per kWh than basically anything else (>$50).

But it basically won't be relevant until we have 12 hours of storage and zero marginal cost electricity 50+% of the year. Then it may be cheaper than overbuilding renewables or capturing gas emissions to cover the last 10-20 percent

lowercase1··on Ethical AI researcher Timnit Gebru fired from Google
Email claims she was told to stop publishing a paper with basically zero reason/conversation matching the tweet.

Hiring has apparently failed to meet goals with zero consequences suggesting a lack of concern with minorities.

I don't think someone misinterpreting disregard for ethical ai research as disregard for minorities is slanderous, heck it might be charitable as the later is known.

lowercase1··on AI researcher Timnit Gebru resigns from Google
It's an abbreviation for any/all/some of those things being more important/interesting than what most of discussion here is about (whether letter/firing is appropriate)
lowercase1··on Ethical AI researcher Timnit Gebru fired from Google
Half of the comments here are focused on the appropriateness of an email after things had already become beyond repair. It's way, way less important than Google potentially preventing publication of damaging research.

It's a bad sign from Google that this is their argument. If they were good on diversity/ethical ai they'd fight on that not on tone. If the facts are bad fight on tone, etc

lowercase1··on AI researcher Timnit Gebru resigns from Google
Stop demanding so much from someone who has apparently been agrieved.
lowercase1··on AI researcher Timnit Gebru resigns from Google
FAANG hires top diverse ethics researchers for good publicity and they demand meaningful changes that aren't in FAANG's interest and get silences/fired resulting in bad publicity

Vs

FAANG hires top diverse ethics researchers for good publicity and they demand clout/unreasonable changes that aren't in FAANG's interest and they get kicked resulting in bad publicity.

Unclear which is happening here. I agree it isn't in FAANG interest to hire these people but that misses the point.
