> If male variance is higher, there are likely both benefits and downsides to it

Yes, but the general concept is that the benefits and the downsides occur in different people. A single person doesn't illustrate "the benefits and the downsides" of greater variability any more than a single person can illustrate variability.

WRT issues of pure sample size, you can see one of the standard supports for GMVH in the SAT Total Group Report for 2018 here: https://reports.collegeboard.org/pdf/2018-total-group-sat-su...

Of the 2,135,788 students who took the SAT during high school, graduated (high school) in 2018, and had a gender, 1,117,329 were female and 1,018,459 were male. (751 had no gender.) 7% of the females, or ~78,000, scored 700 or above on the math section. 12% of the males, or ~120,000, did the same. So at the 91st percentile males are already outnumbering females by more than two to one after being pulled from similarly sized samples.

The greater-male-variability hypothesis says that males should equally outnumber females among low achievers. These tables don't support that -- 1% of females score below 300 in math, compared to 1% of males; 12% of females score below 400 compared to 11% of males.

The usual response to this is that we assume the SAT comprehensively samples high-ability students -- if you'll get a good score, you are strongly encouraged to take the test -- while mostly overlooking low-ability students, who may see no reason to bother.

Thanks for your feedback. Would love to hear more on why you think it is a terrible idea.
Part time with a fixed schedule works the same way.

With flexible hours the average working hours per day are calculated. So if you work for 40 hours a month, a sick day gets you around 2 hours of sick leave.

edit: I think I got you now, you mean day labor, who get payed for how long they can work for changing employers?

I had to google for that, those are "Unständig Beschäftigte". Those are people who are employed for less then a week. They dont get sick leave. I couldnt tell you an example where it is allowed to hire someone like that. Even field workers/harvest helper get a normal contract with predefined working hours.
Your rebuttal is tautological; you're essentially saying "this presentation was only offensive to people who were offended by it". Well, sure. A gauge for how offended people were by it: CERN immediately apologized and ultimately fired Strumia for it.

I don't know how "offensive" I find it, and I'm not a physicist, but I try to put myself in the shoes of a physicist attending a workshop at CERN when someone gets up on stage with a presentation titled "Experimental test of a new global discrete symmetry" and it turns out to be a lecture about "Cultural Marxism", and I assume I'd have been pissed too.
I'm kind of a ruby guy, and I started with the elixir intro from their website. Very clear and well documented. Then I built a website using Phoenix and learnt through that.

Docs in elixir are first class citizen, so everything is very well documented. And just like in ruby/rails land, any question you may google will return a lot of high quality posts with answers!
It would be hypocritical to push for certain issues related to internal EU borders when they haven't met those requirements yet.

It's not hypocritical to ask that passports from that country be treated the same as passports from any other EU country.

An argument could be made for the US to put tighter restrictions on planes coming from those countries. But every EU citizen on the same plane should get the same treatment.

It's a border security issue that should only apply to locations.

In the UK, significantly more women study at university now than men [0][1] (not in Physics though). I am neither agreeing nor disagreeing with Prof Strumia, but simply pointing out that maybe we can agree we've come a long way, and that historial data or past injustices is not a good starting point for policymaking that will affect the bright minds of young uni students.

Thanks. Looking forward to have you on the platform.
They had to apologize because some people were going to be offended, surely, it doesn't mean the presentation is intellectually offensive.

'PR' is different than 'Science'.

'Cultural Marxism' is just a popular term for Intersectionalism, and it's a real issue, particularly on campus.

People should be able to talk about issues that are a little bit uncomfortable.

What you have built looks great and I am sure a lot of work went into it. However, as someone with a bit of trading experience (running a profitable custom-built trading system myself) who has friends that lost money I would like to post a few words of warning to anyone who believes they can build profitable trading strategies on top of someone else's platform: It's extremely unlikely. While you may hear stories of people making money, most of them are pure luck (I recommend the book Fooled By Randomness). To make a stable incoming with trading you must have a consistent "edge", a competitive advantage that other traders don't. Possibilities here include 1. data, that could be be cleaner, more fine grained (L2/L3 book data, better reconstructed, etc) 2. infrastructure. This includes highly latency-optimized server placement, custom API integrations, fault tolerance, dealing with api issues, etc 3. "smarter" trading strategies - What many companies are selling you is that you can make quick $$$ by coming up with some secret trading strategy (3). That's how they make money off you. These charting patterns are pseudoscience. 99% of all edge in crypto trading is in #1 and #2 - infrastructure and data, with relatively simple well-known strategy algorithms. By "outsourcing" this to a platform you are giving up your edge and set yourself up to lose money in the long run.

Also, ask yourself why someone would offer a platform to build profitable strategies instead of simply trading themselves based on their competitive advantage. The answer almost always is: Because they failed to trade profitably and pivoted to selling their (unprofitable) infra.

I don't want to put down what you have built. I know firsthand how hard it is to build some of this infrastructure. I would just like to warn people to not easily trust trading infra providers before they lose money.
> The other issue is that these pianos are hard to come by, since almost every manufacturer makes pianos of the same keyboard size, and pianists are one of the few musicians expected to play on whatever instrument they're given.

This is a good point, but it seems to be determined by the fundamentals of pianos. Moving a piano is difficult enough that I wouldn't expect this to change. We could all switch to keyboards...
I like to play poker (which isn’t gambling) so I walked in to a local casino (I live in Tanzania, so it’s pretty small and run by some Russian gangster) and tried to find a table. They only had house games (including house poker, but it’s rigged) so I decided to play some roullette. I had walked in with $500 USD and decided to just bet $50 on black and consume as many free drinks as I could until I ran out of money.

Everyone was betting on different numbers and kept trying to determine what was “lucky” It was kind of baffling actually. But I wasn’t having much fun, but everyone else was because they thought they were making “choices” thinking they were adding some value to the equation.

After losing all my money, I personally didn’t get much of a rush (maybe because my strategy was to play until I lost it all), but I can see the appeal if you think you have some sort of “skill” at it.

So now I understand. I love playing poker and get a big rush from putting a couple hundred bucks on the line in a big hand, but only because I feel I’m adding alpha or skill to the equation. In the same way, gamblers are getting the same rush that I get from poker because they feel like they are adding some alpha.

Admittedly, though, if I was wagering all of my net worth on the line, I would probably have thought roullette was more exhilirating.

Slots, on the otherhand, I still don’t get. You essentially just sit there and lose money.

A Programmer’s Take on “Six Memos for the Next Millennium”
I disagree. This paper generalizes variants of Paxos - certainly not the class of all consensus algorithms. Moreoever, it generalizes Paxos variants, with different requirements - weaker quorums are always a tradeoff with liveness in the presense of faults.

tldr; I don't see world-changing novelty here, theoretically. There are dozens of other consensus algorithms in the world, some randomized, some not quorum based, etc. This is interesting if you're in Paxos land, trying to tune your Paxos for different fault-tolerance requirements. It's no way comparable to a computational model.

As others pointed out, they're soaked with grease. In fact, the problem is so bad that enough pizza boxes bundled with clean cardboard has spoiled entire ton-sized bundles of cardboard shipped to China.

Cardboard is valuable to recycle, but our inability to remove contaminated cardboard from the recycling stream has really caused major issues. Because of that, China has stopped accepting paper and cardboard products from the US for their recycling operations.

If done right, it's probably always preferable to own the fleet yourself. You can presumably get better economies of scale on purchasing, fueling, maintaining, and insuring the vehicles.

On the current market with human drivers, there are some odd incentives to the contrary though. Using driver-provided vehicles probably helps make the "they're independent contractors" legal argument. There's also the storage yard problem-- if you own a fleet, you're going to have to provide a place for the drivers to come to, park their own cars, and get into yours. I also suspect it lets them cast off the "unknown unknowns" -- damage and insurance claims, underpriced routes. And yes, there are likely opportunities to exploit new recruits by paying below their actual costs.

Once you have self-driving, many of those incentives vanish. Your biggest win comes from calling up GM and ordering cars 10,000 at a time, which a new-to-market entrant can't afford to do.

"For people expecting Tesla like software, upgrade experience, user experience ..."

That sounds like a potential selling point ...

"Otherwise you should just expect nothing much more than a Porsche that has an electrical drive train ..."

For me, the killer features are the CoG and weight distributions of a "skateboard design", achieving AWD with multiple motors, and the acceleration/torque advantages of an electric drivetrain. It appears that the Porsche has all of those.
Hm, my experience with OpenEBS has been... well, not that good. I set up a small cluster and tried a catastrophe scenario by just removing a node. Then i would either get processes hanging in D state, or blazingly fast i/o, which, upon bringing up the node back would result in data loss. Keeping in mind that it was just a simple bash script counting from 1 to infinity to / from a file and OpenEBS couldn't cope with that, i opted for rook and haven't looked back since. It actually runs under /var/lib/rook by default and losing a node or two has no impact, provided your replica count is sufficient. Rook really manages the underlying ceph cluster good most of the time (until you start shuffling osds around), and ceph itself is a wonderful piece of software - it really shows that it came from CERN. But to each his own, i guess.
Focusing on cloning a MAC is a red herring, which we've unfortunately been pushed into from having to continually rebut this persistent nonsensical idea that it's some kind of fixed identifier.

The more likely scenario is a straightforward remote-access trojan installed by a housemate. Every other detail then falls out socially.

Ultimately, prosecution of computer tampering continues to reek of "burn the witch!". With emotionally charged terms simultaneously used to focus blame by ascribing superpowers to the defendant, while deflecting any competing theories as too complex for anyone but the witch.
"A gauge for how offended people were by it: CERN immediately apologized and ultimately fired Strumia for it."

That's a measure of how afraid CERN is of the reaction to it. It's a matter of PR and has nothing to do with Science.

Anyone who's offended by some data in slides might consider not being a scientist. Or rather just easily debunking it if that's the case.

The data in the presentation is uncomfortable, and maybe it's all utterly misrepresented, but these things have a place in polite society.

Finally, here's this juicy tidbit: he's making a case that men are discriminated against in Science. He's given many examples. Then - he's fired right away for highlighting the fact that he's ostensibly being discriminated against? I wonder if that makes a sneaky, upside down lawsuit.

I don't think CERN is the place for any of this, but there should be a place for it somewhere reasonable where people can talk about reality without losing their jobs.

I don't think we need raging bigots, but we need contrarians.
He misled CERN to get his talk into the workshop, didn't provide materials a priori, deliberately gave his talk an obscurantist title, and attacked the workshop (and specific individual scientists and organizers) during the presentation. It was a stunt; he played the workshop. Nobody is going to congratulate him for that.
Not just the cost, but often the complexity reduction in team communication overhead can mean improvements in the ability to add features and services quickly.

If we can somehow figure out how to better sort recycling, some U.S. markets for plastics and paper may emerge.

The technology exists and is in production. Here's a new 90 ton per hour recycling plant, from Bulk Handling Systems, in California.[1] This is a good video to watch to see the whole process. Some of the separation is done with the usual air separators, vibrators, and screens. Optical sorters controlling air jets do some of the separation. This plant has no manual pickers; it uses AI vision controlled robots for the hard separation stations. This is not a prototype; it's a big production plant.

Separating different plastics can be done with near infrared multispectral imaging. Here's a TOMRA sorter doing that in a real plant.[2] That's from 2015.

Finally, here's a big plant in LA which takes in plastic bottles and puts out clean plastic pellets ready for injection molding into new bottles.[3]

China is still accepting US plastics for recycling. It just has to be sorted down to 0.5% contamination, and that's being checked. The standard used to be 1.5%, it wasn't really enforced, and 5% contamination was not uncommon. US recyclers have to upgrade their facilities to the point that there's no manual picking required on the output.

Big cities are dealing with this. Smaller communities have problems, because they don't have enough volume for the newer equipment and don't generate enough material to find buyers.

> Sprints are about accountability

This, so much. If you're missing sprint deadlines, its not necessarily a personal failure as much as a process failure. The solution is to commit to less, to refine your items of work so they can possibly be met in the time you expect. For this to work though, there has to be buy-in from the team members: you can't force it on them.

I've also found that the somewhat artificial sprint goals do act as a good motivation for the team to help each other if they see that the goals might be missed.

There's also the part where you have to be continuously getting feedback and tweaking the ways in which you run the process based on the feedback. If team members feel that this is just another unresponsive management tool designed to get them to work more, it will fail miserably. Instead, if they see it as a construct to provide accountability to stakeholders, they will strive to change and improve the process until it works well.

Ultimately though, the key feature seems to be: the people. If you're not working with a team that's genuinely interested in accountability and helping the product succeed, this process will not work. These are high-trust, highly nimble processes which are completely inefficient if they are actively sabotaged or the promises of good-faith expectations are violated.
