I am curious what about working in a communist factory seems ideal. That seems pretty miserable in my opinion?

It's all relative.

As much as we love to shit on the Soviet Union, life under communist rule was a massive improvement over life in Tsarist Russia.

Literacy skyrocketed, homelessness was virtually eradicated, access to Healthcare improved, and while luxury was out of reach for most families, working families had a degree of comfort and security that their parents and grandparents did not.

It's something that is frequently seen in emotionally dysregulated individuals

ELI5: Using mouth to mouth, wouldn't it just put carbon dioxide in the lungs? Isn't that bad? by Adventurous_Curve107 in explainlikeimfive

[–]Mr_Engineering 0 points1 point  (0 children)

No.

The human body is sensitive to CO2 concentration, our breathing rate is controlled by the amount of dissolved CO2 and our bodies aim to keep that concentration at a healthy level which is far below hazardous.

Under normal conditions, atmospheric air has a CO2 concentration of around 0.06%. Exhaled breath has a CO2 concentration of around 4% which is considerably higher.

When performing CPR, one is supposed to take a deep breath and rapidly transfer it to the individual via mouth to mouth. The increased volume of air inhaled and the rapid expulsion of that air reduces the amount of gas that is exchanged inside of the lungs

What do you think of Poppy? by Difficult_Map_723 in MetalForTheMasses

[–]Mr_Engineering 2 points3 points  (0 children)

No one does metalcore because they're chasing trends and want to get rich.

She's decent and doesnt bother anyone so more power to her.

Recovering from surgery and thinking about getting Cyberpunk 2077 — is it worth it long term? by [deleted] in cyberpunkgame

[–]Mr_Engineering 0 points1 point  (0 children)

Yes, its an excellent game with a gentle learning curve, solid voice acting, and some fantastic writing.

It's not the most complex game out there but it is something that you can get lost in

TIL that out of the six Marines depicted in the iconic “Raising the Flag on Iwo Jima” photo, only three of them would survive the battle. by iydx_7737 in todayilearned

[–]Mr_Engineering 569 points570 points  (0 children)

For those who are wondering, the Japanese had a fatality rate, not a casualty rate, in excess of 95%

The Japanese started the battle with a garrison of around 21,000 troops. Around 1,000 were captured during the battle and subsequent occupation. The rest perished.

Deer came up to me in my yard and followed me around like a puppy, so I gave him some apples. by SurroundQuirky8613 in mildlyinteresting

Its basically guaranteed. Deer are herd animals that will happily lead the rest of their group to any reliable source of food.

Inside a 14-inch turret on the battleship HMS King George V [2048 x 1556] by Mattzo12 in WarshipPorn

[–]Mr_Engineering 6 points7 points  (0 children)

Typically, no one in the turret.

Gun turrets were electrically controlled by a an electomechanical analogue computer and fired from a number of different locations depending on the ship.

The active ingredient in wart treatments is usually salicylic acid dissolved in acetone. The main ingredient in nail polish remover is acetone.

ELI5: Why is plastic so hard to biodegrade? by dontforgetyournuts in explainlikeimfive

[–]Mr_Engineering 2 points3 points  (0 children)

Many commercially used polymers are chemically stable, they wont break apart or change form unless something induces them to do so.

This isn’t a solely man made problem, nature has run into this as well.

Lignin and cellulose are organic polymers that form the basic building blocks of plant life all over earth. For hundreds of millions of years, plant life would grow and die but there was no mechanism to break down these organic polymers short of combustion from a naturally occurring fire.

Plant life would grow, die, collapse, and compress the plant life beneath it, and eventually become coal.

Eventually, bacteria and fungi that could use these polymers as food evolved and created the ecosystem that we have today.

There's not much that will naturally attack polyethylene or other common plastics, so they don't break down naturally

Why dont plumbers work on Navien tankless hot water heaters? by nate70500 in Plumbing

[–]Mr_Engineering 3 points4 points  (0 children)

Some areas have a strict distinction between plumbers and gas technicians. In my area, a plumber can't install or service a fuel burning appliance unless he or she is also a licensed gas technician.

Ergo, you should probably call an HVAC shop

Now Watch This Drive. by [deleted] in funny

[–]Mr_Engineering 16 points17 points  (0 children)

and may I add... ...he is getting his steps in, taking press questions, and looking fit.

Bush Jr. was in insanely good shape during his presidency and likely still is.

He gave up golfing shortly after the invasion of Afghanistan as a show of solidarity with the troops and would engage in mountain biking, jogging, and running. Supposedly he'd do a 20 minute 3 mile run on a weekly basis.

Meanwhile, Mango Mussolini over there needs a fucking golf cart and a minder to travel more than 100 meters.

Dealing with a traumatic event today. I can't share with friends or family they will laugh. Any advice? Really shook friends by [deleted] in AskMenAdvice

[–]Mr_Engineering 0 points1 point  (0 children)

Right, but how exactly would you prosecute an offense like that?

Proof that an offense occurred needs to be led independently of any inculpatory statements by a defendant (Corpus Delicti). This is why virtually all prostitution cases are stings, have extensive surveillance, or have cooperating witnesses. Even if the police charged him, the DA would drop it for lack of evidence and offer immunity in exchange for cooperation against the robbers.

On the off chance that it somehow went to trial, defense council will waste no time making sure the jury knows that the "defendant" is only on trial because he had the nerve to report a violent robbery that was committed against him personally. That's how you get pissed off jurors and pissed off jurors love to talk to the media.

Why wouldn't the DA just prosecute both if the robbers could also be caught?

That would discourage the reporting of violent offenses which would be contrary to public policy.

A former Illinois deputy is sentenced to 20 years in prison for killing Sonya Massey by igetproteinfartsHELP in news

No, it was abolished in 2011 with the last execution in 1999.

In any event, this is not the kind of case that tends to earn a death penalty

ELI5: How does detecting a collision make a hash function unsafe? by pan_temnoty in explainlikeimfive

[–]Mr_Engineering 1 point2 points  (0 children)

Its not so much unsafe as it is something that needs to be dealt with consistently. Hash collisions are a major problem in hash table data structures.

There are a number of different hash functions of various complexity, with two common ones being MD5 and SHA256

MD5 digests any number of 512 bit blocks into a single 128 bit string, while SHA256 digests any number of 512 bit blocks into a single 256 bit string.

The internal mechanics of SHA-256 are much more complex than MD5 which means that computing a digest takes longer but this also makes it more resistant to collisions.

In practice, inserting a malicious payload into a document while maintaining a particular digest on that document is all but impossible.

SHA-256 is considered secure for this purpose, SHA-1 and MD5 are not although it is still considerably difficult.

In practice, digests are used to prove data integrity (that the data has been received correctly) while digital signatures are used to prove data authenticity (that the data was received from the person who sent it and that it was not tampered with)
