saberdancer··on Should I step down as head of Twitter? I will abide by the results of this poll
Yes but the second poll lasted for 24 hours meaning the ban was effectively at least a day - which is option b) tomorrow

I bet he expected to get clear majority for 7 days.

saberdancer··on FTX used corporate funds to purchase employee homes, new filing shows
Get in a ponzi while the going is good?
saberdancer··on Overhyping hydrogen as a fuel
I'm no expert but I think when cars are converted, they can run on both natural gas and on gasoline. Gasoline is used to start the car. Wouldn't that solve the range issue?

Obvious problem in USA is availability of natural gas at gas stations, but that is a chicken and an egg problem - would be solved with more demand.

saberdancer··on Estonia: Become an E-Resident
I've heard that they no longer accept documents in English meaning you have to pay for translation of business documents/reports/etc.

Is this accurate?

The guy who talked about it was an angel investor and is not really impressed with Estonian e-residency anymore.

saberdancer··on Are We Prisoners of Geography?
This is not fascist.

Most countries are made in a way to not allow parts of their territory to secede, even if they "want to do it". Just look what happens in Spain with Catalonia, what would probably happen in Scotland, Texas or California. This is not fascist.

But, you are ignoring the fact that Crimea did not decide to secede but that Russian soldiers (without insignia) became little green men, they forced Ukrainian army to surrender their weapons and leave Crimea. After that Russia organized "a referendum" where Crimea voted to join.

How well these referendums work we can see in Kherson.

saberdancer··on FTX’s balance sheet was bad
You are right, I misread. My apologies.

Still the whole blog and her various public interviews are wild. I know we are operating with the benefit of hindsight but I find her very unconvincing - for example when asked about math in her job she said she doesn't use any really, except maybe elementary school math. That you only need to be able to take some risk (laughs awkwardly).

saberdancer··on Giant satellite outshines stars, sparking fresh concerns for astronomers
500km orbit. It will be in the dark most of the night. They may lose some early evening/morning observation quality but it shouldn't be that bad for the rest of it.
saberdancer··on Giant satellite outshines stars, sparking fresh concerns for astronomers
This satellite is in a 500km orbit. It is in the shade most of the night. Same applies to Starlink satellites.

I have a feeling many people forget about this.

saberdancer··on FTX’s balance sheet was bad
Did you read comments Caroline made on her blog/tumblr?

Not sure of the timeline but she was asking why not double down on a 50/50 bet every time (if you lose) - you can earn "infinite" money but lose only your bet.

I am not sure working somewhere means you are an expert in it. It's incredible these people managed to create a company size of FTX.

saberdancer··on Mass of transactions leaving crypto.com wallets
Exchanges are not a problem.

If FTX kept to their ToS they would have all the funds available and there would be no collapse. But they were greedy, decided to use user funds without authorization, then lost them and the whole thing came coming down.

Exchange which is transparent and truly does not trade with customer assets has no risk involved (other than hacking and similar) and should/would be a massive money printing machine.

saberdancer··on Mass of transactions leaving crypto.com wallets
I am very amazed that crypto prices have not plummeted after FTX revelations. That looks like a very big condemnation of the whole system and the market barely moved.

I am not convinced it will end crypto, a lot of people still want to speculate and the system is too extensive to topple easily. Market not moving seems to be proof of that.

saberdancer··on Musk’s first email to Twitter staff ends remote work
Jack was privately talking the same to Elon. You can read more in the discovery documents (Elon's messages).

The gist was it that Jack believes Twitter should be not be a company and he believed Musk will take it there. Not sure I agree.

saberdancer··on FTX tapped into customer accounts to fund risky bets, setting up its downfall
Usually you can get a copy of the article by going to archive.ph and pasting the paywalled link.

It may not be most ethical thing to do but if you want to read an article or two behind a paywall, I don't think it is insane to do.

This article though seems to be some kind of a live feed where there is not really a lot archived - maybe it works better for paying users viewing things live.

saberdancer··on We will not pursue the potential acquisition of FTX
What always surprises me why does anyone feel the need to steal from users when you are literally "the house" - you are taking a fee on every transaction. Just like in poker - if you are the house, you don't need to take risk by playing at the tables.

FTX was probably hugely profitable before they started stealing.

saberdancer··on Is this the end of social networking?
The point is that today you are always online on your phone. Whatsapp, Viber or Messenger always work. No need to log onto a mainframe and type forum.

I feel that the point made is a good one. Given that we can share what we want directly via instant messengers that everyone has "turned on" all the time, value proposition of Facebook drops dramatically. Anything you want to share you can share directly and immediately get it to whoever you want to see it.

saberdancer··on Satellite images of damage done to Saki airfield in Crimea
Ukraine attacked Russia proper (not just Crimea) before. We all remember Mi-24 over Belgorod but there were also Tochkas fired against airbases (IIRC Taganrog and Milerovo).

I don't think red lines exist. Maybe for using western supplied munitions.

saberdancer··on Why Nagasaki? (2013)
Firebombing cities was a thing. There is little difference in firebombing Tokyo with 200 planes and dropping one "special" bomb.

Second bomb (Nagasaki) was not authorized in some special way. Air force had two bombs available and planned to drop them a week apart. Due to weather it ended up being 3 days. After Nagasaki Truman ordered them to need explicit approval of the president to drop future bombs (appalled at civilian deaths).

It's a tactic Ukraine used before. They rightly assume that most people will understand what happened so they play coy and mock Russia.

It will be interesting to see what Russia says when the "accident" repeats again in another location.

saberdancer··on Dark Matter Doesn't Exist
They had to add more matter in some places and less in others. Estimation would have wrong numbers all around.
saberdancer··on Dark Matter Doesn't Exist
It's not hard to accept existence of dark matter, but it is an extremely flexible, hard to prove answer. If you see a galaxy that rotates differently, you say it has more or less dark matter. It sounds like an easy answer.
saberdancer··on Dark Matter Doesn't Exist
I'm no physicist but if you want to be cheeky, you introduce a "rare dark matter" to a MOND model and explain away those rare instances.

My point is, dark matter explains the observations by being very flexible. There can be any amount of dark matter to fit the observations.

saberdancer··on Ask HN: What's the next big thing that few people are talking about?
Currency is propped up - easy to fall.

They have shown themselves to be blackmailers with energy - no one will trust them again. The war will make Europe less dependent on Russian energy.

Steady gains - I wouldn't say so as they had to retreat from the whole northern Ukraine. In my opinion, Russia lost the war after first week or two. They bet everything on quick collapse of Ukrainian army and now that it did not happen, they are in a war they want to fight with peacetime army against an 40 million country that is fully mobilizing. It's a losing fight for Russia.

How much aid did China send to Russia? Answer is very little to none.

Reason why I feel Russia will collapse is that usually after major defeats, empires fall. We have various factions already jockeying for position and I bet that people like Kadyrov wouldn't mind carving their own part of Russia (independent Chechnya). After Russia depletes their army and manpower in a futile war against Ukraine we can see various other national movements come up. Especially if/when Putin dies.

saberdancer··on The Last Naval Battle of World War 2 (2018)
Bazooka would be more like a rifle on a ship. Much easier to aim with the roll and you get your arms to do the stabilization.

Howitzer works as a mortar or if they are lucky and can aim low, as a non stabilized gun.

saberdancer··on Ask HN: What's the next big thing that few people are talking about?
Russia will collapse.
saberdancer··on Ask HN: What's the next big thing that few people are talking about?
Water falls from the sky. 70% of the planet is salt water. Salt water can be desalinated.

I also think that water wars seem unlikely as if you have energy, you can get water.

saberdancer··on The Last Naval Battle of World War 2 (2018)
To fire a howitzer you need to calculate the angle at which you need to fire and amount of propellant. It seems like an incredibly hard thing to do on a ship and with the enemy maneuvering. It's likely you could only guess and hope for the best.

Usually howitzers fire, observe where the shell lands and then adapt. Here this couldn't work as ships changed positions.

In other words, you are right. Having something that you can point and shoot is easier to do. This might not be true if they could aim their howitzer low but then you get the fact that howitzer cannot be steadied (it will roll with the ship) while a human holding a bazooka can do some stabilization and fire at an exact moment the target is in crosshairs.

saberdancer··on Mysterious holes on the seafloor
Also it's likely that an organization called "Navy" usually operates on top of oceans.
saberdancer··on Mysterious holes on the seafloor
To be fair, Mick West usually finds a very convincing theory that is much more likely than aliens.

He said he'd love to see footage of something that is truly unexplainable. I mean who wouldn't.

saberdancer··on Controversy continues over whether hot water freezes faster than cold
This makes sense to me. Surface layer partly evaporates, it immediately cools down remaining surface layer and then convection spreads it around. It would enable quick "forced" cooling similar to AC and due to convection, it can continue for a long time as warm water and cold water rotate.

Quite counter intuitive. You would expect to have water cooling slow down when it reaches temperature of colder water.
