m0darn , to CSCareerQuestions in People who are 30+, what career moves do you regret in your 20s and/or what choices are you happy you made?

My family doctor referred me to a specialist clinic.

Specialist diagnosed me and made some suggestions to me family doctor. Some medications, some counseling some organizational stuff.

The organizational stuff is what really helps but it's just the 'get organized' stuff that everybody recommends. but with the meds I'm actually able to do it.

m0darn , to solarpunk memes in How is the hydrogen made?

Using hydrogen doesn't emit carbon. But the principal way hydrogen is produced is called steam reformation. It's a process that turns methane (CH4) and water (2* H2O) into hydrogen (4* H2) and CO2 (i think, I'm not an expert). So all the carbon get emitted as co2. So it's not better, and there are a bunch of inefficiencies too. (The reformation process itself, and transportation challenges, and leakage). But theoretically, it does centralize the emissions which would make them easier to sequester so there's that.

m0darn , to Calgary in Woman seeks tougher penalty for Calgary police officer's sexual misconduct

I read a story the other day about several murder charges that fell apart in BC because the cops (willfully) refused to obey evidence handling laws. (I think they managed to still get conviction on lesser charges though, which is something I guess).

The cops have such disdain for the law, it's infuriating.

Putting on the Ritz?

m0darn , to Science Memes in Public trust

The messaging could have been clearer but I'll spell it out for the dumb.

Phase 1:

Don't panic buy medical supplies expecting them to protect you. We don't have enough, and frontline healthcare workers need them to protect themselves and others, you don't know how to wear them and they probably don't fit you properly.

Phase 2:

We still don't really have enough medical grade masks but just fyi: any sort of mouth covering will reduce the risk of a contagious person sneezing into the mouth of a vulnerable person. If you have to go out, please wear something over your face. Cotton is better than nothing.

Phase 3:

A tight fitting mask really is best, it limits a contagious person's generation of aerosolized clouds of viruses, and limits a vulnerable person's exposure to clouds of aerosolized viruses.

m0darn , to NonCredibleDefense in The men who stare at credibility

I don't think the KGB felt like the CIA were always ahead of them.

Aldrich Ames is an interesting character to read about for example.

m0darn OP , to Men's Liberation in Movies that you appreciate differently now?

Yeah definitely. My point was that the existential panic of the mother resonated with me a lot more once I had a kid.

m0darn , to memes in They're just big fans of the cuisine or something.

I have a colleague that has a wife from the Philippines. They live in Canada but are building a house there. He said I should come visit, and I replied something about how my wife would love a tropical vacation. He replied:

Bringing your wife on vacation to the Philippines is like bringing a lunchbag to a restaurant.

... ... ... cool.

m0darn , to Asklemmy in Portable Generators using 20lb propane tanks

Your explanation makes sense to me, an uninvolved spectator with no particular knowledge of generators.

Maybe you direct the generator exhaust over the exterior of the tank? Would that be adequate heat?

My thought was to recall that my 20# propane tank has some sort of safety valve integrated into it that will clamp outflow if there is too big a surge in flow. Flow needs to be 0 for a minute or so for it to reset. But that doesn't explain your experience with the larger tank.

m0darn OP , to Selfhosted in noob hardware question

Okay, I think $80 Canadian for a case, psu, mobo, cpu, & ram is sounding pretty reasonable. I just don't know of its enough processing power for the video stuff. But I guess if not I can upgrade the mobo/cpu or add a graphics card.

Thanks, that channel looks great.

Re offsite backup: Yes I don't have so many family photos that it will be difficult/ expensive to store online. But I need to get them together first.

m0darn OP , to Selfhosted in noob hardware question

I don't have a computer with a bluray drive, only laptops.

m0darn , to Nostalgia in The mall is closing soon

POV: you're 37 and spend 3 hours looking at memes, but don't print any.

m0darn , to politics in Joe Biden pledges $1.7 billion to end hunger across U.S.

Looking at the chart you linked my feeling is that the best way to reduce food waste is:

More/tastier/healthier frozen foods.

This will reduce post sales food wastage, as well as wastage at the market.

m0darn , to Science Memes in No such thing as luck

A few people in here conflating randomness with luck, as if the existence of probabilistic outcomes means that a person can have luck. Some people have fortunate outcomes from probabilistic processes and call that good luck. Some people: negative, and bad. The fortunate (too often) deny the probabilistic nature of the process, and call the unfortunate "weak". The unfortunate decry the inequity of the outcomes and call the fortunate the benefactors of unearned luck.

Ron is doing a great job of demonstrating unscientific, motivated reasoning, since acknowledging the possibility of unfortunate outcomes for the "strong" undermines the entitlements of the fortunate. Which can be very damaging to their psyche/ego.

The problem our society faces is that outcomes often aren't probabilistic enough. The main determinants of fortune are too often not luck, but the ability of one's parents to create opportunity for, and invest in/ support their children. The people that end up with favorable life outcomes have more ability to do the preceding, and/or reinforce systems that increase the probability of their children having fortunate outcomes (ie decrease the probabilistic nature of the favourability of life outcomes).

The meme is a bit of physics and a bit of sociology.

m0darn , to Futurology in China's hyperloop maglev train has achieved the fastest speed ever for a train at 623 km/h, as it prepares to test at up to 1,000 km/h in a 60km long hyperloop test tunnel.

How much extra force does a vacuum tunnel have to withstand to avoid collapse, compared to a regular tunnel?

Dirt weighs ~1.5 tons per cubic meter. So one meter of soil depth is 15,000 N/m^2^ (1500kg * 9.8 m/s^2^) so 15 kpa/m (which is 2 PSI per yard of depth).

Vacuum can't provide more force than atmospheric pressure. Atmospheric pressure is 100kPa or 15 PSI. Adding vacuum load adds the equivalent crushing force as digging a tunnel 6.5-7m deeper (7.5 yards). I don't know why this is totally insurmountable. Take a thick walled concrete tube, coat the outside with some sort rubber, bury the tube and pump out the air.

Yes you need to seal between sections, and keep sections aligned. I'm not a civil engineer or whatever but it doesn't seem crazy hard. It just seems like... not important. It seems a lot more expensive, and less beneficial than just making a good surface transit network. Who cares if it would let me get from Vancouver to Seattle in... half an hour? If it's already taking me an hour to get to the station and find parking, and get through ticketing/security/ customs.

It's only 2 hours from Surrey to Everett in a car (ignoring customs). Maybe we should just like have a bus?
