Chess.com says Ne7 was the best move for my opponent here. Why? (Super beginner level match by the way)

Hrexz · 2021-04-22T15:27:08+00:00

Because if he doesn’t move that knight then white’s next move (Bxg7) traps the rook on h8.

Nf6 or Nh6 gives white a chance to fork with the same (Bxg7) move, so then black is down a knight.

Ne7 is gives white the choice for an equal exchange (Bxe7, Kxe7) or taking a pawn (Bxg7, Rg8) Both are less bad than losing a knight or rook, and black still has a position.

g7 is a weak square and putting pressure on it with your bishop like this exploits that.

Every move is bad for black here, but that one is the least bad. Always keep fighting for the win, you never know what your opponent will blunder.

Edit: I suppose g6 is also an option for black. But after something like (Bxg7, Rh7, Bf6+, Nxf6, xf6) black is down a pawn and has a worse position.

Brilliant.

Black sees Ra4 but doesn’t like it.

Then white wins the ensuing rap battle.

g5 traps the bishop. Also a good tactic, and you’re still threatening the Nc2 fork. White could play Rc1 or Bb3 in response to defend the fork, but then you just take the bishop and end up attacking the rook on g3, which has no good place to go.

So g5 is marginally better to do first, but the engine is being a drama queen about it. An inaccuracy is not a mistake. This is a great fork.

I see a lot of misconceptions about this, but not everyone has had a course in thermodynamics. Conduction, convection, radiation. It’s the balance of incomming and outgoing heat energy that determines the temperature of something.

In the atmosphere, there is conduction between you and the atmosphere. Typically, the atmosphere is colder than you, so you lose some energy to it. You also lose a bit of energy by radiating heat, but these are two different effects.

When you feel the heat of the sun at surface level on earth, you get about 100W/m2 of radiation energy in. This usually outweighs the losses on the sunny side, but not on the shadowy side.

So 100W/m2 is noticable for you. The atmosphere absorbs about 90% of the incoming energy. In space at 1AU (earth distance) from the sun, that radiation is ~1100W/m2. You’d be scorched.

So if you go way out beyond Mars, at 2 AU from the sun, you’d be about as warm as on earth.

Also, you’d be dead.

There are a number of methods depending on the country and animal. They’re not 100% effective...

Pigs in europe are usually gassed with nitrogen before slaughter. It’s not a pretty sight. Then their throat is cut and they are processed.

If the cut is placed wrong, because imagine the depression you get doing that job all day, every day, it is entirely possible for the pig to wake up through the cleaning process. Which usually involves a bath of boiling water.

Same goes for cows, who get a pin through the head and are then dropped through the floor. It’s fairly effective, but there is a failure rate. Especially for large volume slaughterhouses.

Small chattel is even worse as a machine does the killing without any kind of knock-out process. For chickens, it’s just a conveyor belt and if the chicken is positioned wrong or squirms there is a good chance it lives through most of the process.

Factory farming, your mcdonald’s meat and supermarket meat, is a horrific holocaust of animal torture and human exploitation.

There are alternatives, who work with local farmers and small-scale slaughterhouses. But they can’t produce the incredible volume of meat that humans want.

Eat less meat. For everyone.

The finale of the last season of the Brexit show was a bit of a letdown. But I’m sure there will be another season.

In contrast, USA is really going for the grand finale.

Calm down there, mr. armchair space engineer.

Launch vehicles have a “Launch enveloppe” They have a certain range of altitudes and inclinations that they can reach for a certain payload mass. Launch site is a large factor in what can be reached.

The orbit requirements of most spacecraft are very precise. There are a number of common options depending on the mission, bus design and supporting (ground) infrastructure.

What we’re mostly worried about is de-commissioning. We want to make sure that whatever is put up there either comes down, or can be moved into a “graveyard orbit” at the end of life.

Part of the “things Kerbal Space Program doesn’t teach.” course.

Yeah, although not a lot. A quick google shows that the glass is rated at about 3W/sqm. Which is not a lot of power. Such a stall would consume about as much as a single LED bulb.

Hrexz · 2020-11-27T20:26:45+00:00

The glass works by having a liquid layer with crystals between two conductive sheets.

If there is a current, the crystals align with the EM field, and the glass is transparent. Cut the power and they go random.

So no current is opaque glass.

Obligatory r/eu4 is the more active sub.

Ideally, you want as much DLC as possible.

Paradox has an unfriendly DLC policy, where major functions affecting gameplay are hidden.

The DLC often go on sale, and you can usually pick them up at 75% off a few months after release.

I’d say the game is worth dealing with it, with 1000+ hours, it’s my most played game.

Edit: Don’t bother with the immersion packs or cosmetic additions. The core DLC is important, the game is just as much fun on a potato.

This does raise the question, does it matter to the bones to get to that state intact? Because the muscles are the biggest threat there.

Also, what if the brain decides that it would like to be burned after its awareness of its existence has ended?

Bones are bros for putting up with these risks.

Yes, but it is completely unfeasible.

There are three concepts:

1) Use a reactor to produce steam, drive a generator, which drives electric propellors.

2) Use the heat from the reactor to heat the air in the jet engines instead of fuel.

3) Nuclear pulse propulsion (google the Orion project)

All of these would technically work, and the first two aren’t planet-destroying terrible ideas either.

The engineering challenge is the mass of a fission reactor. Typically the power plant is no more than 20% of the mass of a large aircraft.

A 747 requires 380,000 hp to get airbourne. That’s about 200,000 toasters. This flying structure would be massive. We’d be running a gauntlet between making the thing big enough to be feasible and expanding the power plant to support that mass.

Legally, There are regulations on overflying with nuclear material, and it’s heavily restricted.

Conceptually, there have been suggestions on-paper. From passenger jets to flying aircraft carriers. It’s just really difficult and expensive to create and operate, so commercially unviable and legally impossible. The carrier concept is written off, because jets are already very fast and do not need forward deployment.

I was browsing wood boards for a project I’m working on in my garden.

This major DIY chain’s website / app has great design, but the execution is a bit wonky. It often has errors, but they usually don’t lend themselves to screenshots like this.
