Little Brown Mushrooms, the most important guideline to amateur mushroom tasting is to only eat half of each mushroom, so that the coroner can figure out which ones are toxic.

Very sad. I drive through there (1 block west of 41st and Knight) often. Hopefully the citywide speedlimit reduction on residential streets can help this city implement needed changes to physical infrastructure and traffic law enforcement.

Canadians should mail letters, ring them up, fax them if they can, to let them know that any reasonable person would consider this goal post shifting a complete abdication of their responsibilities.

Everyone likes to believe they’re thinking independently.

Can you elaborate on that claim?

I exercise some critical analysis, but for the most part I just have trust in human ambition. For example: the reason I believe human CO2 emissions are driving climate change is not because I've looked at the evidence and evaluated it for myself.

The reason I believe that human CO2 emissions are driving climate change is: that seems to be the consensus of people that have worked hard to impartially develop expertise and gather data to understand climate science.

There are two important systems at play

1: Scientific research, which harnesses human ambition by rewarding impartial research and discoveries which overturn old assumptions/paradigms.

2: Journalism, which harnesses human ambition by rewarding impartial reporting on various fields of human interest. (Reporting is why it seems to be the consensus of the scientific community)

The impartiality of these systems is (has always been) under assault by capitalism (which also derives its power by harnessing human ambition) and so one must, to an increasing degree, evaluate the appropriate level of personal mental effort to allocate to identifying biases in the reporting.

we'll do everything we can to make sure approvals happen quickly... ...and routinely

So you'll do nothing because that would change the routine?

Presumably anybody that does this gets their code integrated into the training data right?

Just to spell it out for people: myriad means 10,000 but has been used as a stand in for "huge variety" for so long that people don't know that anymore.

I'm basically a secular humanist, and I've heard the statement that Catholics aren't Christians, in person, a few times. The two times that come to mind were from very different people (a Chinese Christian that lives in Beijing, and a Canadian Christian that lives on an apple orchard in southern Ontario). Both of whom were coworkers I spent some time with while travelling for work (different jobs, about 10 years apart).

I've always shut it down as a wildly offensive thing to say, and not worthy of discussing. So I've never gotten a real explantion for why some Christians believe it. Is it a common opinion?

I 100% agree they should be flipped. Also, Don Draper was lying when he said that, so it's like doubly apt. Canada feels bad for the US but also is living in their shadow. The USA does think of Canada and has an irrational need to put us down.

 

My 6 year old son has been skateboarding for almost a year, he likes it a lot and I'm very proud of him. I've filled up my phone taking videos of him.

He's approaching the age where he'll be able to skateboard at the school without me, and while I'm happy to go watch him often, I recognize he won't always want me there supervising.

I'd like him to be able to film himself, can anyone weigh in on good options for him? The idea is mostly to document, and to review so he can see that he is achieving his goals etc. Picture quality is not really required for those goals.

I think these are what would be good:

-easy to control -easy to aim -Easy to review footage -robust (I'd also like to be able to take it skiing) -slow motion mode (he loves seeing slow motion videos from my phone)

Do you guys have any pointers I haven't thought of? Any recommendations? Go-pro? Insta 360? Idk....

 

I'm not saying that it's likely or that it would have any effects.

I live in Vancouver Canada, my house was built in the 1950's and the basement has the floor joists of the kitchen [above it] exposed.

At that time forestry here was felling massive ancient trees. I'm curious how precisely I can establish a maximum age of the trees felled.

Obviously I could count the rings visible on the joists and subtract that number from 1950, but not having the tree's full diameter limits measurement. I understand it's possible to compare relative ring sizes with existing [cross referenced] data sets to date timber.

Does anyone have any experience doing this or able to point me in the right direction? Any resources I'm unlikely to find on Google?

 

I'm trying to achieve variable speed control on two brushed DC motors powered by a 3s or 4s LiPo battery (~12V or 15V). This is for a nerf blaster I'm modifying, which is why I'm not using a pre-made speed control ie I want control over the shape/layout. I'd like to vary projectile speed with a thumb knob.

I just finished watching ElectricMonkeyBrain's YouTube video on the TL494 PWM chip.

I was initially planning to vary the duty cycle with a potentiometer on the chip's control pin, to get a PWM signal and feed that into a MOSFET. But in the video he mentions that the chip has an integrated over current protection function. Ie the chip will

monitor the voltage across a sense resistor in series with the load 

and will

kill the output if the sensed voltage/current goes above a reference voltage

It occured to me that I could actually adjust the reference voltage as a way to control the motor speed.

Would this be a better way to achieve speed control and protect my motors/battery? Or is it a terrible idea altogether.

 

I have recently rewatched the movies Inside Out and Home Alone, having previously seen them while childless (I.O. as a young adult, H.A. many times at various ages).

The parental behavior draws a lot more of my attention, and it really changes the movie for me.

The parental panic when they don't know where their kid is, or if they're safe, just hits so much harder. Like, it's not that I didn't understand the movie before, I guess I just have a new appreciation for the parents emotions.

Are there any other movies that you appreciate differently now that you have different experiences?

 

I know this isn't build a pc, but everything over there is so gaming oriented I thought I might get better advice here.

I'm a noob that wants a home media server for sharing photos of my kids with my family (across the country), video library sharing to some family members, and streaming my music collection to my phone (and maybe my dad's).

But I'm considering ripping my father in laws extensive bluray collection (well seeing it up so he can rip them into my library) so I reckon a full tower is required for HDDs.

I'm imagining unraid, with a big pile of used drives. What I like about that approach is that I can economically add storage as the video library grows as I/we rip. Or are used HDDs a false economy.

I think the only processing intensive thing in the use case list is ripping and video library sharing. I have no concept of what sort of processing is required. Should I get a graphics card?

There's a Lenovo TS-140 (E3-1226 V3) available available used for $80 Canadian. Is that a good place to start?

My friend John mentioned that he has been feeling depressed lately. There have been some bad things in his logs that would make anyone sad but the things that normally bring him happiness aren't doing anything for him lately. It's something he has struggled with in the past. He has a counselor and has been prescribed anti-depressants. I'm not worried about him harming himself.

My understanding is that part of being a friend to someone facing depression is reaching out to spend time with them.

How much should I reach out? I don't want to harass him, and he has a wife and other friends (that are emotionally closer than me). His wife for sure knows what's going on, but I'm not sure about his other friends (our kids go to the same school so I actually see him more then most of his friends).

I understand that sometimes depressed people neglect chores in their life, should I ask his wife if there's anything I could help him/them with?

 

The bake off one:

Sister in laws:

 

I glove you.

 

My neighbour (40/m) ("N") confided that his recently retired father (70/m) ("G") has started going to the casino twice a day (all day but he comes home for dinner).

G's losses affect the food they eat (multi generational household).

N doesn't really know what to do. I'm not so concerned for N, moreso his mother/G's wife.

It's not my business but, when I was a kid my boyscout leader committed suicide after gambling away his house so I'm pretty sensitive to this sort of thing. I'd like to help if I can.

Any advice?

 

I'm having trouble wrapping my head around the scale of the problem of nuclear waste. If we took all the nuclear waste produced in a year and evenly blended it into all gasoline burned in a year would the radiation be deadly? Dangerous? Detectable?

It's easiest to get numbers for the US.

2 000 000 kg of waste per year

510 000 000 000 Liters of gasoline

Obviously this isn't a real proposal, although I think it would reduce carbon emissions...

 

Wikipedia says

A superhero or superheroine is a stock character that typically possesses superpowers, abilities beyond those of ordinary people, and fits the role of the hero, typically using their powers to help the world become a better place, or dedicating themselves to protecting the public and fighting crime.

So yes, he is definitely dedicated to protecting the public, but it feels wrong to call him a super hero. What do you think?
