pstrateman··on BYD builds fastest car
Is it a production car if they have made one and have sold zero?
pstrateman··on Humans have caused 1.5 °C of long-term global warming according to new estimates
It's not the high income countries choice.

If you reduce your consumption the cost of oil will fall towards the cost of production and middle/low income countries would consume it.

The only way someone in a high income country can prevent this is to buy oil and permanently bury it.

If you truly believe that then the options for what happens are universally bad.
pstrateman··on Humans have caused 1.5 °C of long-term global warming according to new estimates
The simple reality is that humanity is unable to reduce greenhouse gas emissions without an alternative that is superior.

For every ton of CO2 that the west has reduced in the past decade China has produced three tons of CO2.[1]

We need another breakthrough on the scale of the Haber process.

pstrateman··on A hot day, a fan provides little benefit when the temperature exceeds 35°C
The "feels like" temperature weather reports use is an approximation of wet bulb.

Have they not heard of wet bulb temperature?

The chart in this wiki article is really good at showing the various effects.

pstrateman··on Segmenting Credit Card Customers with K-Means: A Fun Dive into Clustering
I'm gonna say his analysis of the groups is just wild guessing.

> Mostly married with low credit limits and high utilization rates. These customers may benefit from tools and programs to manage their credit usage.

> Mostly single women with low c redit limits and high utilization rates. Offering credit management tools and financial literacy programs could be valuable for this group.

pstrateman··on Colorado scrambles to change voting-system passwords after accidental leak
Wide scale fraud isn't necessary when elections are decided by 10k votes.
pstrateman··on Broadwell's EDRAM: VCache Before VCache Was Cool
I believe the high cache skus were Mac exclusive.
pstrateman··on Who is the skeleton buried by a secret society under this Baltimore bar?
>the dissection triggered a hunger response in people

this is supposedly from the formaldehyde

pstrateman··on Simone Giertz talks about invention
How does this article not mention anywhere that she had brain cancer?

That's almost certainly the answer to the headline.

pstrateman··on AI Medical Imagery Model Offers Fast, Cost-Efficient Expert Analysis
Two thirds of the title is true.

That's pretty good.

pstrateman··on Web Browser Engineering (2021)
Most of the things you think of as static video files (say youtube) are actually video segments operating more or less exactly the way live streams work.
pstrateman··on Web Browser Engineering (2021)
> As an aside, video decoding is offloaded onto hardware, so it's not as battery intensive as it used to be.

This is technically but not usefully true with most videos on the web today.

The video decode itself is accelerated, but each frame passes through JavaScript to be composited.

The only time video is fully hardware decoded is when it's a simple video element to a static video file.

pstrateman··on Is population density the reason Americans can't discuss politics?
I think this guy misses something pretty significant.

Many Americans have professional business relationships with people whom they vehemently oppose politically.

Politics is simply bad for business.

pstrateman··on Money Buys Happiness, Even If You're Already Rich
How would anybody else know?
pstrateman··on Solving climate change by abusing thermodynamic scaling laws
Reducing production is simply impossible.

There's billions of people on earth who are desperately poor compared to even the poorest American.

There is absolutely no chance those people just accept their position as ultra poor.

If individuals want to reduce their CO2 output the only viable strategy is to buy and permanently store fossil fuels.

pstrateman··on Solving climate change by abusing thermodynamic scaling laws
Simple math unfortunately.

To offset global human CO2 production you'd need to biochar all plant matter several times a year.

pstrateman··on Britain buys semiconductor factory for defence purposes
It's much more effective at extremely high frequencies used in compact radars, like the kind used on fighter jets.

pstrateman··on Agitating homemade PCBs with ease
The YouTube video acknowledges the over engineering in the title.
pstrateman··on Even solar energy's biggest fans are underestimating it
> The grid has become so expensive due to the cost of fire proofing infrastructure

Power in California was incredibly expensive long before any of the money was going towards fire proofing.

pstrateman··on Smartphone Tethering: A Bigger Grind Than It Needed to Be
Pretty much all of the FOSS AOSP alternatives leave it to the user.
pstrateman··on Paper types ranked by likelihood of paper cuts
I haven't gotten a paper cut in years.

So much less paper in the world.

pstrateman··on 20% more powerful perovskite solar panels enter commercial use
Who cares?

The panels themselves are basically free.

The mounting system and the inverter are the expensive part.

pstrateman··on He emptied an entire crypto exchange onto a thumb drive
It's the only thing you really need money for.

If you don't pay your taxes in your nations currency you go to prison.

pstrateman··on Batteries start to rival gas on California's electricity grid
The more solar/wind on the grid the harder it is for gas peaker plants to respond to the instantaneous shifts in supply.

I won't what the cost of power from a solar+battery facility is that had enough batteries for seasonal variations.

pstrateman··on UltimateAntiCheat
Why?

Modern games all have 10GiB+ updated constantly that you're not disassembling.

What's the difference?

pstrateman··on UltimateAntiCheat
This is still playing defense.

Anti-cheat needs to be more or less a kernel level remote code executor.

pstrateman··on Microsoft donates the Mono Project to the Wine team
Yeah if this doesn't come with a substantial endowment it's not a donation.
pstrateman··on Breaking down a record-setting day on the Texas grid
Paying people to stop consuming is just an accounting replacement for interruptible power.

The net effect is more power generation available, not less.
