Comment Next: infection of plastic by vacteria and mold (Score 5, Interesting) 88

Soon (within 300 years) - electric shortage everywhere, because the plastic insulation becomes mold substrate - all gaskets, rubber gloves, insulation, polymer-based O-rings slowly disperse - plastic-based paint is digested from surfaces So we need a lot of new materials... but at least Nature stood up as our garbage man and does the work instead of us

Comment metal sodium as reactor coolant??? ARE YOU MAD??? (Score 0) 334

"liquid metal sodium as the reactor coolant" as a chemical engineer, I stopped reading here.

Any large-scale industrial technology utilizing metal sodium means grave danger to its environment: one drop of water OR one molecule of oxygen turns it into flames and/or hydrogen.

Again: if this material start to burn, cannot be put out with water: that would cause hydrogen explosion.

If you combine that with radioactivity, you get a nightmare situation really soon: unstoppable radioactive fire.

PLEASE, NO.

1. pull out carbon from the crust
2. take its chemical energy from it
3. use huge amount of taxpayers' money to pump the CO2 back to the crust (do not forget handling+safety costs forever)
4. Profit!! for the old energy companies, everyone else just sucks

TL DR: do not pull out carbon from the crust, that will cause excessive damage and huge problems up here.

Popular YouTubers Are Building Their Own Sites (bbc.com) 91

An anonymous reader shares a report: Whether he's showing off astronomically expensive computer gaming hardware or dumpster-diving for the cheapest PC builds possible, Linus Sebastian's videos always strike a chord, and have made him one of the most popular tech personalities on YouTube. But Google-owned YouTube gets most episodes of Linus Tech Tips a week late. Now, they debut on his own site called Floatplane, which attracts a much smaller crowd. "Google has been very, very good to me," Linus says. "But it's a lot of eggs in one basket." And with a staff of two dozen, he cannot rely on the company to continue being what he calls his "benevolent overlord". He is not the only YouTube star looking for alternatives.

For a long time there have been tensions between those creating content on YouTube and the company providing the platform, ranging from disputes about ad revenue, to copyright problems, and even rows about the way videos are recommended to people. Many successful YouTubers are now sizeable companies in their own right, and are seeking to safeguard their futures. For the last few years, Linus and co-worker Luke Lafreniere have been investing in their own platform called Floatplane. The pair stress that it is not -- and never will be -- a YouTube competitor. But they hope to provide a platform for existing video creators with a loyal audience, who might be willing to pay a few dollars a month to directly support the video-makers they love.

The Subtle Effects of Blood Circulation Can Be Used To Detect Deepfakes (ieee.org) 45

An anonymous reader quotes a report from IEEE Spectrum: This work, done by two researchers at Binghamton University (Umur Aybars Ciftci and Lijun Yin) and one at Intel (Ilke Demir), was published in IEEE Transactions on Pattern Analysis and Machine Learning this past July. In an article titled, "FakeCatcher: Detection of Synthetic Portrait Videos using Biological Signals," the authors describe software they created that takes advantage of the fact that real videos of people contain physiological signals that are not visible to the eye. In particular, video of a person's face contains subtle shifts in color that result from pulses in blood circulation. You might imagine that these changes would be too minute to detect merely from a video, but viewing videos that have been enhanced to exaggerate these color shifts will quickly disabuse you of that notion. This phenomenon forms the basis of a technique called photoplethysmography, or PPG for short, which can be used, for example, to monitor newborns without having to attach anything to a their very sensitive skin.

Deep fakes don't lack such circulation-induced shifts in color, but they don't recreate them with high fidelity. The researchers at SUNY and Intel found that "biological signals are not coherently preserved in different synthetic facial parts" and that "synthetic content does not contain frames with stable PPG." Translation: Deep fakes can't convincingly mimic how your pulse shows up in your face. The inconsistencies in PPG signals found in deep fakes provided these researchers with the basis for a deep-learning system of their own, dubbed FakeCatcher, which can categorize videos of a person's face as either real or fake with greater than 90 percent accuracy. And these same three researchers followed this study with another demonstrating that this approach can be applied not only to revealing that a video is fake, but also to show what software was used to create it.
In a newer paper (PDF), researchers showed that they "can distinguish with greater than 90 percent accuracy whether the video was real, or which of four different deep-fake generators was used to create a bogus video," the report adds.

Comment By EU Council: not controversial, not free (Score 1) 52

"Controversial" is an understatement.
According to EU Council's press release, "the elections were neither free nor fair".

In plain English in Belarus there is a bloody dictatorship by Lukashenka for at least 15 years.

Comment Amateur scripting "languages" are the worst (Score 1) 137

The most dreadful when a hacked-together quick-n-dirty scripting tool pretends to be a real language, then picked up and praised by amateurs, because... it is fast to trow together something in it.
When a language is not statically typed, all hopes are lost: no larger system can be reliably built upon sand.

Python: when control gets to a location, and turns out no such property exists on an object? So you have to test all branches to prove a minimum correctness? Seriously, are we in the 80's like with BASIC?
Bash: when a single space within a directory name diverts your script to execute the command-line parameters by default... worst decision of all times
Perl: you got no built-in support for switch-case, but you have the freedom to pick among *17 different switch-case implementations* from the semi-official language repo... insane
BAT files: when you have to introduce recursive subroutines in order to process a string splitted to fields... ridiculous
PHP: once it seemed to be a good idea to throw together C functions into a script, but strictly without any planning which would take more than 1 minute...
cmake: when they decided the order of function arguments by tossing a coin...

my god, I have to use all of these stinking piles of bad ideas daily...

No, your 300 years number (about the waste reaching natural activity levels again) is absolutely incorrect - by several orders of magnitude.

With direct disposal of the waste - no postprocessing, just dumping it, as it is done by US, the natural levels are reached only after 250,000 years!
See Composition of Spent Nuclear Fuel pp 19.

"Anything with a half-life that long is, by definition, not that radioactive"

Untrue and/or not applicable, Sir.

"Transuranic wastes, sometimes called TRU, account for most of the radioactive hazard remaining in high-level waste after 1,000 years." [USNCR]

- Decay of the waste fuel mix is a complex process.
- The activity decreases by a factor of 1000...2000 during ~35,000 years.
- But the starting activity is so high (20,000 rem/hour) that ~10 rem/hour is still remains after tens of thousand years.
- By US law, you need 0.2 rem/hour surface activity to declare it "you may handle it by bare hands". By contrast, it will have so high activity that if you keep it in your hands for a few days, you will probably die from it.
- So yes, fission tech is immoral, it will hurt us even after thousand years, and your grand-grand-grand-grandchildren will blame you too, to be so neglectful.

Comment ...and the day after tomorrow... (Score 2) 186

...when the new reactor has to be decommissioned, say after 35 years, our descendants have to wait only 35,000 years to handle these by bare hands.
Unless there will be
- an earthquake
- a tsunami
- a serious accident within the containment or at the nearby
- a terrorist attack
- a war
- a declining of law and order (I know, it is impossible, as every well-established state lasts longer than that)

Fission technology is immoral: you enjoy the benefits now, and export the costs to the forthcoming generations.
