drran··on Covid origin studies say evidence points to market
It VERY unlikely that there were two separate events of transmission of two different variants of SARS-CoV2 virus. It looks like a) virus originated somewhere else and China was just a good place for virus to spread, b) it was two separate deliberate attempts to spread virus in China.

> Fair has nothing to do with it. Contracts don't need to be fair, and often aren't. They just need consideration. If we sign a contract whereby you give me your car, bank accounts, and house, for $1, that's a valid contract.

It will be a gift. Gifts are valid, but they require free will of the gifting party. Gifts, without free will, can be easily canceled by court.

In this case, exchange is not fair, it's a scam, while in case of GPL, exchange is fair (code for code), so it's a valid open contract. You use my code, I use your.

I assume, your point is that US government doesn't represent Chinese immigrants, right? This is true. Why this is a problem and what solution to the problem you propose?

drran··on The true cost of linked lists
Algorithms and programs are different things. An implementation of the algorithm is called a program. Big-O is used for comparing of algorithms. An algorithm can be implemented in different ways. Performance of the program can be measured precisely. Different implementations of the same algorithm will have different performance. When precise information is available, assumptions are useless. When precise information is not available, at design stage, assumptions are used to compare different algorithms.

Just by folding the rope you will be able to reach 6ft/2 = 3ft. Check your formula, please.
drran··on I cheated on my Microsoft interview (2019)
When stretched, the length of the rope will be two straight lines plus part of the circle. The length of the segment can be calculated using a formula for horizon. Then we can create an equation: (s arc distance to horizon for h)*2 + delta = (d straight Distance to horizon for h)*2, or d-s-delta/2=0.

d=sqrt(h(2R+h)) km/m (see https://en.wikipedia.org/wiki/Horizon#Approximation )

s=R*arccos(R/(R+h)) (see https://en.wikipedia.org/wiki/Horizon#Arc_distance )

sqrt(h(2R+h))-R*arccos(R/(R+h))-delta = 0

6 foots is about 2 meters.

sqrt(h(2*6371000+h))-6371000*arccos(6371000/(6371000+h))-2 = 0

h=306m

drran··on The quest for fusion energy
It just a vortex.
drran··on The quest for fusion energy
We need to understand the nuclei. The only way to do that is to create macro-scale working models of nuclei, to see what happens inside them. The «walking droplet» kind of experiment is a step in the right direction. These experiments are much, much cheaper than any other experiment in quantum or nuclear physics, but nobody wants to fund them.
drran··on Zelensky Compound NDA
We lost the previous war with RF, then paid a huge price for that in 1932-1934. 7 million adults (this number is accepted by RF in 2008) and 23 million children (this number is not accepted by RF) were murdered by hunger during «Holodomor».

We will do everything possible to avoid repeating of the genocide, but RF is a strong opponent with a lot of resources, so we need to be smarter, see better, be better equipped, and be faster. Otherwise, they will just push us inch by inch to Western border.

drran··on Entanglement and superposition are equivalent concepts in any physical theory
Superposition is a mathematical conception, while the wave in a physical guitar string is a physical thing.

Superposition is the mathematical description of _our_ uncertainty about position of a particle.

The physical wave in a guitar string does redistribution of mass in the string using energy. The physical wave does some work, while superposition does nothing, because superposition is used for predictions only. When we know the location or other properties of a particle after a measurement, then its superposition is meaningless.

They share nothing in common in the physical world, while they share a lot in mathematical description of their behavior.

drran··on Did the W-boson just “break the standard model”?
IMHO, we should not put all our money into a single basket. Instead of overfunding few science projects and underfunding everything else, we should fund projects with potentially good ROI. For example, IMHO, we should fund research in LENR instead of HENR, because LENR will be much more useful. LENR reactor can be installed at home, or in a plane or spaceship, while HENR will require a separate town.

I did download of a film using torrent via StarLink once for performance test. I saw up to 5 Mbytes per second in torrent client, which is impressive speed to have in woods. Sadly, StarLink is not suitable for audio or video calls yet, because of frequent pauses.

drran··on Sunken Moskva Could Be the Biggest Naval Combat Loss in 40 Years
200k reservists cannot join Ukrainian army because of lack of equipment and money. I have no truck, for example, so I cannot move a few tonnes of communication equipment rapidly, so my combat-readiness is low.
drran··on Sunken Moskva Could Be the Biggest Naval Combat Loss in 40 Years
Russians invade other countries because they are not capable to produce good things by themselves. They need someone to build advanced weapons, armor, ships, planes, rockets, goods for export. Good warriors are bad makers, usually.

For example, if you are incapable to build a house, then you need to hire someone to build it for you. If you have no money, but you have an army, then you can just enslave him instead. Russian Empire is the jail of nations.

drran··on Sunken Moskva Could Be the Biggest Naval Combat Loss in 40 Years
I have no idea. Before the war, cars from the USA were delivered by sea in shipping containers to Odessa. Now, Odessa in blocked by Russians, so cargo must be shipped to EU first, and then transported to Ukraine via Poland. There are some Ukrainian firms, which are providing logistic. I can also ask my mentor from Britain to help with delivery. I put my email into profile details, if you have a truck for me, because I badly need a truck. I'm OK with the truck from Chornobyl, because we are living close to Chornobyl anyway, but we cannot repair it because of lack of parts and because the main quarters were left due to risk of missile strike. We are all in the fields now.
drran··on Sunken Moskva Could Be the Biggest Naval Combat Loss in 40 Years
This prediction is correct for pre-war Ukraine. We lost Crimea without a fight. Now we have 8 years of experience and will to fight, because everyone lost somebody they know. However, Ukrainian army is poorly equipped. 200 thousand reservists cannot join Ukrainian army because of lack of equipment. We are trying to squeeze the last few drops from our reserves.

We badly need new trucks. I have a driver (I'm lieutenant), but have no truck, because my truck was used in Chornobyl, so it's not operable now because of 30 years of out of service at conservation. If I have a truck, I can swap my cabin from Chornobyl truck to new truck and create a working communication station, but I cannot find a cheap truck to buy.

If you have a barely working truck, please, sent it to Ukraine, Rivne, Ukrainian Army, 55 OPZ, 1 battalion.

drran··on The Backdoor That Keeps Russian Oil Flowing into Europe
If Ukraine will won a case in a USA court, then Russian oil can be confiscated by USA government (for USA government).
drran··on Why I'm in the Army Reserve – an explainer for my friends in tech
Illegal/immoral orders can be silently sabotaged and reported later. Look at RF and Belarus. Russians are happy to kill Ukrainians, while Belarussians are wrecking Russian military trains. They received same orders.
drran··on How to Keep 600 Kilograms of Kazakh Highly Enriched Uranium Safe
Military help sent from West to Ukraine is at about 1/30 of military equipment sold by Germany and France to RF.

Ukraine (literary "Area of Defense") has better morality and better men because of huigh numbers of wars fought in last thousand+ years.

drran··on How to Keep 600 Kilograms of Kazakh Highly Enriched Uranium Safe
They were Soviet warheads. Soviet Union (officialy) was created by RF, Ukraine, and Belarus. Also, Ukraine and Belarus are members of UN.
drran··on What are you doing, WordPress.com?
These servers will not be accessible with normal DNS turned on, so Google may index it technically, but links will not work for normies, because they know nothing about DNS or networks. Technically competent users can switch DNS server, so they will.

Yes, it will be possible to show ads, but ads may link to sites within the parallel DNS system only.

Hackers, who want money for their work, are called security experts.

drran··on What are you doing, WordPress.com?
We can start Internet 2.0, a HackNet, just for hackers. Create your own DNS server, register non-commercial hacker sites only, create catalogue and decentralized search engine for these servers. Commercial operators will see no value in this parallel network, because google will be unable to index it, so spam problem will gone.
drran··on Show HN: A plain-text file format for todos and check lists
IMHO, you are mixing TODO lists and task management/planning software. No, I don't know a good task manager or business process manager for command line. Instead, I created a simpler TODO list manager, called `td`[0], which supports flat TODO lists only, and use directories and command-line generators to manage todo's. `td` prints top item only, by default, leaving little room for procrastination. I'm keeping one `TODO.md` file per project instead of one large TODO file for all todo's.

drran··on “This shouldn’t happen”: Inside the virus-hunting nonprofit EcoHealth Alliance
RF develops and holds biological weapons, including plague. Moreover, it suspected that SARS-CoV-2 was released from «Vector» BSL4 lab: https://jglobalbiosecurity.com/article/10.31646/gbio.41/ . So, why RF is not nuked yet?

Moreover, if biological weapon will target Russians only (by asking them a question in the Russian language, I suppose) then it's completely legal for Ukraine to use such biological weapon to defend itself against Russian aggression. Madness is an important part of MAD.

drran··on “This shouldn’t happen”: Inside the virus-hunting nonprofit EcoHealth Alliance
Even if scientists are competent, virus can be leaked because of someone else stupidity. For example, look at blast in «Vector» lab, Novosibirsk, RF, Sep 16 2019, where Russian first responders entered into biosafety level 4 lab without protective equipment, then opened every door checking for fire and stole some equipment. How you protect your lab from that?
