Multiple millions by thousands of years. Probably yes.

We have lot of nuclear waste. Can you take it?

Nuclear meltdown, evacuation of nearby cities.

You forgot to include the decommissioned reactor and waste water.

Life of hundreds of millions were/are/will be affected by Chornobyl. Nobody can calculate real death toll of Chornobyl accident because it's impossible to control radiation. Moreover, nobody wants to pay for those deaths or partially lost health.

So, for safety, turn off coal first, then turn off nuclear.

In 2024, US was at 384 gCO₂/kWh, while Germany was at 344 gCO₂/kWh.

You arguments boils down to «it's OK to wipe a continent once in a while, because nuclear energy is the safest energy option per megawatt produced».

Quote: The winters in Germany are often colder and the country's climate is generally more continental. The south of France enjoys warmer Mediterranean temperatures and milder winters.

> CO2 in the atmosphere is also long lasting, do you have a problem with that type of storage?

Yes, we have problem with CO2. The solution is to use Solar + Wind + Hydro + Batteries + long lasting storage. Nuclear causes more problems than it solves unless it used to make nukes also.

Nuclear power plants require international laws and international cooperation for insurance, because one serious incident, such as Chornobyl, can wipe a continent.

In Ukraine, profits from all nuclear plants will cover damages, caused by Chornobyl, in 1000-5000 years IF nothing more will happen to Chornobyl or other an other nuclear power plant in those years, which is unlikely.

I will happily pay YouTube for just one feature: dub all content I see into my native language.
oneshtein··on I am giving up on Intel and have bought an AMD Ryzen 9950X3D
AFAIK, I have 2x DDR5 non-ECC memory (`dmidecode --type 17` says Samsung M425R1GB4BB0-CQKOL). Your command tells about SECDEC (single bit error correction, double bit error detection).

It looks like DDR5 supports SECDEC by default. :-/

My `dmesg` tells:

    EDAC MC1: Giving out device to module igen6_edac controller Intel_client_SoC MC#1: DEV 0000:00:00.0 (INTERRUPT)
but `dmidecode --type 16` says:

oneshtein··on The math of shuffling cards almost brought down an online poker empire
2^128*52 is 6656 bits, or 30x more than 2^226, so it will work IF those bits are independent. If CSPRNG is used, such as AES128, it will use 2^128 seed, which is not enough to cover all 2^226 permutations. If PRNG sequence is reused to generate more shuffles, then the next shuffle can be predicted from the previous one.

CSPRNG AES256 with 2^256 random seed is safe.

CSPRNG AES128 with 2^128 (or less) random seed is not safe.

> Turns out that an even easier way is just to assign 128 bits of randomness

52! is roughly 2^226.

You cannot address all 2^226 positions with a 2^128 address generated from 2^64 seed.

oneshtein··on The Universe Within 12.5 Light Years
Something like Alcubierre drive must move fast (0.1% of c at least), be very heavy and dense (to create protected environment inside), and emit lot of high energy gamma rays because a spacetime with negative energy will accelerate light a lot.
oneshtein··on The Universe Within 12.5 Light Years
Photon is a wave. It oscillates. It's proven. Math model doesn't account for this to make calculation simpler for human beings.
oneshtein··on The Universe Within 12.5 Light Years
Red shift allows us to roughly calculate distance and time, so we can multiple time by frequency of light to calculate number of oscillations or cycles and then calculate loss of energy per oscillation at average.
oneshtein··on The Universe Within 12.5 Light Years
Yep, usually FTL means FTc.

Geminga?
oneshtein··on The Universe Within 12.5 Light Years
Yep, this is what he saying, but this is not what photon does. Photon must perform different amount of wave cycles to reach 1 meter or 1 trillion metters. These cycles can be counted.
oneshtein··on The Universe Within 12.5 Light Years
Light is a wave, so it waves something to propagate itself in space and time. Physical photon does countless cycles to leave the star and hit an eye.

It's not an easy task from the prospective of a photon, which can be easyly proven with just two little slits.

oneshtein··on The Universe Within 12.5 Light Years
So c is the speed of light in the fabric, right?
oneshtein··on The Universe Within 12.5 Light Years
Cherenkov radiation is a proof, that FTL is possible. We just cannot accelerate enough. However, «burps» from blackholes are proof that blackholes can do that. To achieve singularity, outer layer of blackhole core must spin at a FTL speed anyway.
