Yes, or maybe more accurately - we are the American equivalent of Formula SAE Germany. The German teams are significantly more advanced and better funded, with some of the teams running custom built electric inhub motors (something that's unheard of here in the US)

I am currently on San Jose States Formula SAE team - we merged our electric and combustion teams last year to go all electric since it's where the stiffest competition exists. If we could secure sponsorships we'd love to take our car to Germany!

This is not an accurate take. It does not require some great expertise to identify edible mushrooms, and in cultures where mushroom consumption has been common for hundreds of years (such as Russia), basic identification techniques are well known.

There are some edible mushrooms with poisonous look alikes - there are plenty other edible mushrooms without those deadly cousins. If this gentleman had made it 70+ years without issue, it is rather unlikely he would have some issue now.

As the saying goes: there are old foragers and bold foragers, but there are not old and bold foragers.

From what I understand, one of the big bird issues with turbines is that birds of prey like hawks, eagles, and falcons don't generally look forward but down as they scout for prey, and thus are likely to fly into turbine blades. I believe some turbines have cameras systems to detect birds in the vicinity of the blades and either make a noise to alert the bird or maybe even bring the turbine to a halt. This is really only an issue for large scale installations though, obviously wouldn't apply to low lying roof installations.

The aero packages for these vehicles create a pretty significant amount of downforce at relatively low speeds - for example, our car last season produced ~140 lbs of downforce at 35 mph.

Edit - A lot of that comes from the rear wing though, which the green team didnt run for this particular event.

Yes, this car uses powered ground effects (PGE) to achieve the necessary downforce at low speeds (they mention this in an instagram post)

In Formula SAE in the US, PGE systems are not allowed, but in the European equivalent they are.

Take a look at the Speirling at Goodwood Festival of Speed for an awfully mean fan car. https://www.youtube.com/watch?v=xtvT2XYlcOY

Although the other comments are correct about the 30mph optimization for the aero package, this car uses active underbody aero (aka, fans) to create additional downforce even when at a standstill. See the recent runs of the Speirling at Goodwood festival of speed to see a purpose built "fan car" in action.

Interestingly, this setup wouldn't be allowed due to rules in Formula SAE in the US but is legal in the german competition cause those teams are just built different.

Edit - Quick plug! If anyone is interested in supporting FSAE and the awesome engineering that goes into these cars, I am a member of the San Jose State team and our aero team is in need of HPC access to run their CFD simulations. My email is in my profile. Cheers.

I learned that the two of them were housemates for a period of time while taking a mycology class from Alan - can you imagine being a fly on the wall in that place? What a colorful group.

I have to say I think it's quite possible and comical that the professor interpreted your work on two of the three questions as additional evidence that you did know it should be an "and", since I would guess relatively few students would attempt any more than _one_ permutation if the assignment only asked for one.

Damned if you do, damned if you don't.

Did you know that hemp was not used in Dr. Bronners soaps until the 90s?

I think it's well know that Emmanuel Bronner suffered from some mental illnesses - the man lost his family to the holocaust and was sent to a mental asylum upon arriving in America. Life was not necessarily kind to him but he seemed to do alright with the cards he was dealt.

I know when I first learned about the soap, I had a similar sentiment as you. As I have learned more about the history of Dr. Bronners, I have come to see that it is hard for me to imagine some of the trials that the generations before us have faced.

Everybody has different needs, so I can respect that it's not a perfect soap for all people.

That being said - are you diluting it or using it straight? I usually dilute 4 parts water to 1 part soap for handwashing / showering. Also, the Eucalyptus scent was harsher on my skin than others - I prefer the unscented, almond, or peppermint varieties.

Could you clarify by what you mean as "it wasn't very nice"?

I've been using bronners for a decade and have recommended it to more people than I could count. I've never had anyone tell me they downright disliked the soap - with the exception of peppermint, some folks don't like the chilling sensation.

Follow the instructions on the bottle for dilution as well, makes like easier and spreads out the soap.

I'd imagine you aren't the only person who may be having a hard time adjusting from a remote freshman year to an in person sophomore year! Outlook is a big part of these things, and sometimes optimism is a great tool even when it seems unwarranted.

I'm a cali guy, so I can't comment on Texas A&M from experience, but... is there a computer lab available for working on your CS assignment? At my school our lab was lovingly referred to as "the dungeon". It was a place where you would spend long hours working with others on hard problems. As others have mentioned, shared hardship goes a long way towards friendship, and I am still close with some of those I met and worked with there!

One thing I'd add to the advice given already is to get out and socialize sooner rather than later in your degree. When you are a freshman, everyone is in the same boat as you, trying to piece together a new group of friends. It can seem daunting, but know that you're not in it alone!

After freshman year, you'll still certainly be able to make plenty of friends, but I found that first year to be especially primed for socialization.

As others have mentioned - ask people to hang out outside if class. Get to the clubs you are interested in, even if they aren't full of other CS majors. Look for events sponsored by the school, like concerts or dances or sports games, and try to find folks who are interested in a good time there.

Best of luck to you!

P.s. - where are you going to school? If you feel comfortable sharing, you could potentially get some advice on campus specific activities (if there are any alumni around).

I am not 100% on HN policies regarding flagging / renaming threads, but I do see articles get renamed on a fairly regular basis without getting flagged into dead status first? Is there not a mechanism to suggest a different title without getting it pulled entirely?

I think the click bait title is a good knee-jerk reaction test, and I would suspect a fair number of folks flagged the thread without reading the full article. In the spirit of open discussion and intellectual honesty, this seems like a failure.

A more descriptive title would probably be for the best, though.

"The point of the polices was to counter the incredibly destructive result of the surge of cocaine, crack, heroin use in the mid 1970s and early to mid 1980s."

This would be plausible if the policies were focused on those drugs exclusively. However, I see the draconian policies targeted towards cannabis, hallucinogens, and amphetamines as pretty ample evidence that the "war on drugs" had much wider ambitions than curbing the usage of these hard narcotics.

Edit) To your point of folks speaking harshly of our current drug policies - look at where we are now, 50 years later. A nationwide opioid crisis created by pharma companies. A generation, if not two, of young men and fathers locked up in prison with little to no room for upwards mobility. Communities, already economically deprived, losing stability, obliteration of the nuclear family core, and enduring oppressive policing policies. So yes, I think its entirely fair for a new generation to shit on the war on drugs. Even if the policy was formed with good intentions (which is, frankly, debatable), it is still bad policy.

Not directly related to the article, but - I am extremely disappointed that this article was flagged. It certainly displays the general inability for people to openly analyze ideas and narratives that (at first glance) appear to go against their beliefs. I feel like this type of censorship across platforms is only adding ammunition to the persecution complex of those who are already skeptical of the vaccine.

While this is true, it overlooks the selection pressures that exist on nucleotide selection. If I recall correctly, the canonical bases are relatively robust to radiation in the ir, visible, and uv spectrums when compared to other nucleotides. http://europepmc.org/article/PMC/4181368 Not sure if that's the correct article, but it's a good starting point on selection pressures for nucleotides and heterocycles.

That is to say - just because visible light is more energetic does not mean it is guaranteed to cause more damage.

(I briefly worked in Tor's lab - a truly incredible chemist and teacher)

Well, yes and no. If they just wanted to heat things up, they'd throw the reaction over a Bunsen burner or some other appropriate heating element. So while I agree that the reactions are speeding up due to an increase in available energy, I'm hesitant to say it's the same as simply "heating things up".

During my rather short stint in a synthetic chemistry lab in college, I learned that it was a relatively standard practice for folks to "nuke" their reactions in a microwave in an attempt to speed things up. Certainly, nobody wanted anything to get ionized in these situations... So, to me the idea that biological systems may be able to pick up additional energy from local RF fields, and that this increase could potentially have adverse side effects, does not seem totally implausible.

Isn't DMT biosynthesized endogenously in most mammals? https://pubmed.ncbi.nlm.nih.gov/31249368/

I think it would be fascinating to know more about the anabolic/metabolic pathways that create these molecules. Could it be we are seeing similar products created as mutations of core synthetic pathways?

4:52, but I had already given up on the first page once and then had to give it another go. Like others mentioned here, a lot of these are unfortunately common in the wild - the ones that always set me into a rage are placeholder texts that remain in the field as I type and the inability to tab through fields.

Could you elaborate on what you mean by "compromised"? Sure, they can no longer be stacked 7 units high, but I am skeptical that cutting out a handful of windows and a door is going to make a container structurally unsound for the purposes of container homes.

Cut out a whole side wall? That's a very different story.

Maybe it's just me, maybe it's just a snapchat "feature", but one of the first things that struck me was the idea that this young woman sent the rant out to something like 250 people, of which a nonneglible portion was from her school (and had additional ties to the cheer group).

Comparing this to my own experiences - I know I said plenty of things in high school which would have landed me in hot waters had they reached the wrong ears. But they didn't, and while there was certainly some luck involved, there was also discretion at play. I kept my personal opinions personal and limited to other individuals or groups that I could trust.

So I guess my question is - does discretion play a role? Is there a difference if I whisper to a friend that I'd love to kick somebody's ass or if I post the same idea to a public social media space where it can be seen by a larger audience? What if I yell it out real loud during a break? What then?

It will be fascinating to see how this case plays out, as I can see valid arguments on both sides of the table. Free speech is key, but if we want schools to have any chance of succeeding there must be a way to protect students who are being unfairly targeted.

While I entirely agree with the sentiment of this post, I often find myself wondering - how does one effectively combat this attitude without making a full circle? How is anything to be established in society without some sort of "might", so to speak? Just a thought that resonated with me when I read your comment.

Not a physicist, so maybe I took the wrong gist away from the article, but - it seems like what they are saying is that systems that are generally modeled by complex equations have always had real valued equivalents that were known.

So it's not that the complex representation isn't a useful mathematical tool, but that it was an alternate representation that was easier to work with. Can you represent a spring mass dampening with all real valued quantities, even if it's a real piece to work with?

I used Google Glass in person for about 10 minutes, and after so much oh-ing and awing over the tech, for me it was pretty disappointing to experience. It felt like I was using a cheap Android system from 2012 overlayed onto reality and, uh, it wasn't that great. That being said, I only got to see a few basic apps in action, and maybe I didn't get the full tour of the hardware's abilities.

Personally, I think that VR will win out, even for AR applications (or maybe my semantics are incorrect). I can imagine a VR system that uses external cameras to mimic a person's natural field of view and overlays additional information in the process of displaying it. It seems like a more available route to a fully immersive "augmented reality" than the current glasses based prototypes.

An alternative (or additional) solution that I have considered is making it easy for a user to provide keys to others to allow access to content.

You could use some combination of the two sets of controls to provide pretty granular privacy control over all sorts of things.

Could you elaborate a bit on what you mean by this? I have seen similar comments elsewhere but don't really understand what is being suggested.

Wikipedia sums it up pretty well

https://en.m.wikipedia.org/wiki/Clarence_Saunders_(grocer)#W...

tldr - the short sellers were given five days to find the necessary shares (compared to the standard 24 hours). That's a lot of time in 1923, and enough shares came in to get them out of the corner.

Clarencr Saunders (the Piggly man himself) was left with no way to repay the loan that allowed him to set up the squeeze and was forced to walk away from a truly revolutionary business he had built.

Read Business Adventures, as mentioned in other comments. Cannot recommend enough.

Curious as to what others here think about the idea that the Tic Tac UFO could be some sort of high energy particle beam being controlled from the ground?

My mom unfortunately passed from cancer, but she was able to get proton beam therapy for a tumor that would have been inaccessible with traditional radiation. This, as I understand it, is because a proton beam sheds the majority of it's energy at the very end of it's flight, allowing internal tissues to be targeted more directly.

I wonder - what would it look like if you made a proton beam and pointed it to the sky? Could you create a glowing area, much like the Tic Tac, that could be used to throw off enemy radar? I am legitimately curious, as my physics background is so so at best.
