deepnotderp··on The Future of Hardware Is Software
Also, it’s worth noting that OoO brings more than just ILP/scheduling, it also brings MLP and dynamism. Take for instance latency hiding a cache miss or a mispredicted branch. Stuff like this is impossible to know in advance, no matter how much you redesign your language to expose ILP.

Itanium got maximum penetration in HPC, so people were aware of this. The challenge is that GPUs and DSPs (many are VLIW) are even better at parallel.
deepnotderp··on Youth suicide attempts soared during pandemic, CDC report says
CFR is very different than IFR. And early data is worthless on this, since only the most severe cases would’ve been tested and confirmed.
deepnotderp··on Forty percent of the world’s shipping consists of fossil fuels to be burned
Also as a reference, German electricity prices are up and their Co2 emissions are up due to unreliable renewables.
deepnotderp··on Forty percent of the world’s shipping consists of fossil fuels to be burned
So still more expensive than gas, with unreliability to boot?

That is a massively misleading way to frame it. Hydro is well known as one of the cheapest sources of energy period. The problem being if you happen to have a river of energy. Bundling hydro (and natural gas!) into “renewables” to claim that all renewables lower grid prices (when most people take it to mean solar and wind are impractical) is misleading.
deepnotderp··on TSMC’s Arizona Culture Clash
Given that Intel had undisputed process leadership until 10nm it seems that the "Taiwanese work culture advantage" works in mysterious ways.
deepnotderp··on TSMC’s Arizona Culture Clash
None of this makes sense.

1. Long shifts are normal for fab operators in the U.S., eg Intel.

2. Certain engineers are always on call if an emergency happens, also true at Intel.

3. Samsung, not exactly the “live slow and enjoy life” type of culture as an employer operates fabs just fine in the U.S.

deepnotderp··on Intel claims new i9 is faster than M1 Max
To be fair, comparing TSMC’s nodes vs Intel’s isn’t exactly fair for CPUs since Intel has always had performance advantages beyond density such as Ion, cobalt, air gaps, etc.

Edit: Ion= on state current

deepnotderp··on Intel claims new i9 is faster than M1 Max
To all the commenters: This is claimed on a power adjusted basis: https://mobile.twitter.com/witeken/status/147844103741682893...
deepnotderp··on Indiana life insurance CEO says deaths are up 40% among people ages 18-64
Social isolation is well known to probably be the number one factor driving drug abuse (see eg Rat park experiments). Lockdowns, no school, etc…

In teenagers this has already caused a spike in mental illnesses.

deepnotderp··on Predict 3D position of flying bugs and pest to shoot down them with a laser
You could fire a pulse with lower power to check what the return distance is to see if there’s anything in the way. This is what some wireless power transfer approaches do essentially iirc
deepnotderp··on Companies that had successful pivots
Intel- memory to microprocessors?
deepnotderp··on Chasing After Carbon Nanotube FETs
Switching speed isn’t really what people are after with CNFETs, broadly speaking they’re after parameters like increased drive current per unit of gate capacitance.
deepnotderp··on Why Electric Airplanes Face Such a Tough Haul [video]
1. Due to the need to accelerate, HSR is only really good for 100 mile+ trips, beyond the range eVTOLs are being proposed for.

2. Hsr only goes point to point, stops and door to door transport isn’t really feasible, and those last couple of miles take a lot of the time.

3. HSR is extraordinarily expensive in infrastructure costs and most city pairs don’t have the passenger volume to justify it.

deepnotderp··on The Importance of Price Signals
I meant CSI haha, that was a bad typo
deepnotderp··on My Path to Financial Independence as a Software Engineer
Compound interest wasn’t the key here. The key was salary increasing rapidly and the 600K+ salary at the end. He could’ve not invested at all and still gotten there.
deepnotderp··on The Importance of Price Signals
Except CSI across the board has increased incredibly fast compared to historical trends since 2000 ish, not just in cities.

EDIT: I meant CSI, Case-Schiller Index, for house prices, a tragic typo XD

deepnotderp··on Technology Behind the Lilium Jet
1. You missed the point of the analogy

2. This entirely depends on the speed. For high speeds an airplane can be more efficient than ground based transportation. See von Karman efficiency, eg : https://www.researchgate.net/profile/Omer-Kinaci/publication...

3. Exotic materials like aluminum and carbon fiber? The BMW i3 adopted the latter for example

4. A better way to look at it isn’t whether air transport will ever be cheaper, but whether air transport can be cheap enough to be worth it due to the unique advantages it offers. Eg flying in a straight line, flying faster, no traffic, relatively easy autonomy compared to ground, etc

deepnotderp··on Technology Behind the Lilium Jet
And why are you so certain that flying personal transport is not economical?

Certainly the history of the automobile should show that such statements can look ridiculous in hindsight.

deepnotderp··on Technology Behind the Lilium Jet
A small town doesn’t have the density for a HSR link, see eg China’s HSR debt.

A 120 mile link at 14 million a mile is more than a billion dollars.

deepnotderp··on Dramatic growth in mental-health apps has created a risky industry
Yes, see eg suicide clusters
deepnotderp··on Is The World Deglobalising?
Has it ever occurred to you that the answer might be that they’re just better at it than us due to decades of experience at scale?

Not to pick on you in particular, I see this sentiment a lot. China is no longer cheap labor, their dominance in manufacturing is due to expertise.

deepnotderp··on Is The World Deglobalising?
Just want to underscore this point. The ability to produce complex molds quickly and cheaply is a huge advantage for China. Metal 3D printing however may indeed be a potential game changer here.
deepnotderp··on Low interest rates in advanced countries have pushed money into real estate
Texas also has high property taxes and Houston has very lax zoning regulations, both things designed to prevent real estate speculation.

This is purely a result of the fact that water is so cheap and water rights don’t incentivize water saving technologies.

There are residential and agricultural technologies that dramatically reduce water usage. For instance drip irrigation. Also the city of Las Vegas recycles almost all the recyclable water and consequently is extremely efficient at using water

deepnotderp··on Low interest rates in advanced countries have pushed money into real estate
When people say “investing” in real estate they generally mean buying existing houses, not investing in construction projects.

And “throughout the ages” is nonsensical, slavery is as old as civilization and yet abolishing it led to wealthier and happier societies.

Imagine if instead of real estate speculation that capital went into creating new technologies and businesses.

Indeed! Would love to start, do you have a good email address to reach you? Mine’s in my bio
deepnotderp··on Low interest rates in advanced countries have pushed money into real estate
By separating the productive activities of construction and administration from the parasitic activity of rent seeking.

Yes, who uses steel anymore? /s
