@Ross Scott Okay, I finally bit the bullet and watched the whole thing. This is what I have to say.

The reports of reinfection were caused by the fact that the majority of tests used pretty much everywhere (except in a couple of countries who have their own production lines) were counterfeit, and showed almost random results.

No amount of statistical research will help if it is based on reading coffee grounds.

There are two ways to get rid of heat: phase change (melting/vaporization) and heat transfer.

In case you don’t want to refill some sort of consumable, you are stuck with heat transfer.

Heat transfer (in watts) is proportional to the temperature difference, area of the separation surface between two environments, and the properties of said separation surface. In case one or both environments are liquid or gaseous, another factor is the “refresh rate” of this liquid or gas.

 

Heat transfer (in watts) is fixed (determined by your computer).

Properties of the separation surface (i.e. radiator coating) are already as good as they get (it’s the manufacturer’s job).

Ergo, in order to minimize the temperature difference (read: CPU temperature), AND/OR minimize the air “refresh rate” (read: fan speed), you have to maximize the area of the separation surface.

It’s as simple as that. There are no miracles in life. The only reason why hydraulic cooling exists is purely mechanical impossibility to install huge radiators directly on the heat-emitting elements, which necessitates one or another way of transferring heat from said elements to said huge radiators.

Therefore, this phrase

Quote

Water cooling still uses fans: you have the pumps, [water] goes through the radiator, and the radiator uses fans

is wrong. Not only can you completely get rid of fans by pumping water through huge enough radiator, but you can also achieve good passive cooling without even using water. In November 2016 I sent you a Scythe Ninja3 Rev В radiator, which was more than enough for me to cool my Haswell-E Core i7 CPU with fans staying completely still, i.e. in 100% passive mode. (Did you use it, by the way?).

 

Alas, this is impossible for gaming, because (1) GPUs produce an order of magnitude more heat than CPUs, and (2) it’s mechanically impossible to install anything like the aforementioned Scythe on a GPU. Therefore, water cooling.

 

55:17

You don’t have to “trust” passive cooling. Nothing stops you from attaching fans to the aforementioned huge radiator, then setting your BIOS in such a way that these fans will be turned off as long as the CPU temperature is sane. Then for 99% of time you’ll get a 99% silent PC (1% of noise is for water pump), and once a year, when you’ll be doing exceptionally heavy rendering on an exceptionally hot summer day, the fans will turn on.

 

55:25

It’s the polar opposite.

The absolute air humidity (water mass divided by air volume) is of no relevance to your well-being. What you (and mold) feel as “humidity” is relative humidity, which is the current absolute air humidity divided by maximum possible absolute air humidity at current temperature.

Therefore, humidity goes down when your air heats up. Your computer is making your room drier.

I noticed that when Americans talk about socialism in any (even remotely positive) way, they always ignore that the ultimate goal of USSR was not to [distribute something goods something something natural resources blah blah], but nurturing a new type of human.

The one which will spurn wordly blessings and reach for Gnosis.

The one which will consider dedicated work for his brethern the culmination of his existence.

The whole enormous apparatus of government propaganda was aimed at building an intensely anti-consumerist society, in which taking more than you need would be something disgusting and infinitely disgraceful, like coprophagia.

And it almost worked. (The reasons why it didn’t are a topic for a whole separate discussion, but it definitely was in no way impossible).

 

Point is, if you are looking at USSR trying to borrow something good from it, and first things that catch your eye are free medical care and education, free housing, controlled economy, protection of labour etc., then it’s like saying that a book is a great doorstop because it has proper size and weight.

 

Also I must say that reading the chat was almost physically painful. The sheer porridge that people have in their heads made my hair stand on end.

Chinese is one of the easiest languages in the world. It is much easier to learn than English.

  • there are no tenses
  • there are no articles
  • the alphabet is 100% phonetic
  • it has 2 orders of magnitude less phonetic combinations than English
  • words have way more intuitive etymology
    Spoiler

  • you can easily become fluent in Chinese without learning a single hieroglyph
  • there are no compound words

…and so on. In fact, out of all languages on Earth, English was one of the worst possible candidates for becoming lingua franca, but here we are. (It doesn’t mean I don’t like it, mind you. Also I consider my own language a bad candidate as well).

Cells don’t get “toughened up” as they get older. It’s just that damage to the cell nucleus manifests itself when the cell divides. Therefore, the faster cells divide in a tissue, the more vulnerable this tissue is to radiation.

Cells start dividing slower as we grow up. Also, in different tissues the division rate is different, that’s why e.g. mucous membranes are more vulnerable to radiation than bones and nerves.

- Is there a way to tell if you’ve received an e-mail, or it got caught in the spam filter?

- Yes, if I’ve received an e-mail, I just do a search for the e-mail address, or keywords to it.

I have conscientiously listened to this part about a dozen times, but still failed to understand what you meant.

 

This question bothers me too, for 5 or 6 years in fact. It wouldn’t be a problem if you were using a properly working mailbox – I could just patiently wait for an answer, like I usually do. But alas, you use Gmail, and Gmail is infamous for its brain-dead “spam” filtering that randomly and UTTERLY SILENTLY removes random e-mails that its obtuse algorithm doesn’t like.

 

If I were to propose a solution, I’d advise you to make a boilerplate text saying “thank you for your e-mail, I’ve read it, but unfortunately I can’t answer you right now, stay put”, then sending this text as reply to every e-mail you’ve read, every single one, as soon as you read it.

Such two-step replies have long since become standard anywhere there is no possibility to guarantee timely reply, from tech support to public authorities.
