The cultural element in Japan of post WW2 salarymen and their stature in society definitely lends a unique point to this story.

But in a more general case, with the aging population in the US and the around the world, with a large majority seemingly becoming more comfortable with being online. (personal anecdote: my parents are around 60, worked all their lives and had no need or even desire for the Internet or computers, etc. But now in their retirement, they've taken to it more freely and are trying out more apps, social networks, etc.) I've always wondered why there hasn't been a more compelling app or service that existed that targeted this demographic to help them find activities or form stronger local communities.

I've seen Linkages advertising around the coffee shop I go to, and the concept seems close to what I'm thinking, but I don't believe it's caught on, yet I can definitely see a need in that space.

I guess I'm envisioning something more casual to use for that generation: "looking for someone to walk around the neighborhood daily" or "have tea with" or "go gardening with" or "go to the local art class", Or "having a beer and watching the game". This must already exist, or have been attempted right?
No. The host could be a robot, and the contestant could be a robot, and the could play the game a million times. The robot contestant who chose to switch would win 2/3 of the time, while the robot contestant who chose to stay would win 1/3 of the time. It's math, not psychology.
From the article I think I only saw one comment that involved gender - I think it’s pretty unfair to ascribe gender motivation to many of the responses (as embarrassing to read as they are).

Secondly, what is the implied norm that the author wants - you can’t disagree with someone of a different gender who has a higher IQ than you?
Indeed, and we still see the same behaviour in many male-oriented public forums, including this one. And of course the subsequent denial of their own sexist and misogynistic behaviour.

"It was nothing to do with her being a woman!" they will cry, ignoring the unconscious bias that led them to such an angrily disproportionate response in the first place.
Part of the problem is convincing people that you are legit. I face a few challenges these days

first off, I don't have a degree so that's one battle, but i'm an isolationist so that's battle #2 and its much harder to win.

During the first half of my career it was easy to find work because i was green and not charging much. towards the middle part i relied on a network of contacts and finding work was super easy. then i decided to isolate myself - i dropped all my contacts, deleted everything i had ever created (several websites that i ran for years), removed myself from social media and now work is very difficult to get. I didn't even realize this was the issue until recently.

In order to fix this:

1. I have started to rebuild my social network and have set up references

2. I now view social media apps as Personal Branding applications and use them as such

3. I built a portfolio site and added a bunch of my old projects to it

4. Look for little projects i can knock out in a few hours or days, work on them, and add them to my site

Old-Money Billionaires Are Chasing New Tech Riches
It seems to me that BPD means obsessing about the social domain and ASD means obsessing about the non-social domain. Both obsessions are amplified by social exclusion due to being neurodivergent. Obsession leads to systemizing.

Baron-Cohen's theory is a fantastic near-miss IMHO. I mean, he was clearly onto something. Women are warmer in temperament, men are more autistic, have better mechanical and spatial reasoning skills. But what Baron-Cohen may have missed is that those are symptoms rather than causes. Symptoms of a difference in innate value function in the degree to which the social domain is valued. But that's value at a very low, instinctive, perceptual level. Autists might still like socializing, but they do not get a kick out of processing social information that neurotypical people do, so their entire thinking apparatus down to low level neuronal circuits will be shaped by different optimization constraints, from birth onward.
Interesting didn't know that, thanks
“I don't think people really realise how extreme the cultural divide between _immigrants_ and _natives_ are in the West. The US would have elected Trump in a land slide were there no _minorities_”

So whites are native to the US but blacks or hispanics aren’t?
Unfortunately, your experience with the HL-3170CDW is extremely common. We had it happen and it is very well documented on Amazon. We found an Australian company that detailed the issue in their "fault of the week" page:

http://fixitfastelectronics.com/mfc9330cdw-9140cdn-emboss.ht...

The TLDR there is that the HL-3170CDW has a sharper-than-normal lift off angle from the fuser roller (the part that fails). Inexpensive toner is more sticky than the Brother-brand toner, so it causes undue fatigue on the part.

We had this same issue happen to us about 1000 pages after switching to an ultra-cheap, pour-in toner option. We first replaced the roller with a cheap one from Ebay that ended up causing the printer to overheat. Then we bought a custom manufactured roller from the aforementioned Australian company. That one has lasted us more than 3000 page so far, even with the cheap toner.

Note: if you elect to change the roller yourself, don't touch the heating element / bulb inside of the roller with your fingers!
Don't sweeten the deal. With the regular odds, after 12 games you will only be ahead ~61% of the time. You have to play a larger number of games to be relatively sure you win and the other accepts they must be wrong. The number of games increases by quite a bit if you sweeten the deal.
I wrote a simulation as an exercise (not to convince myself, just to illuminate the logic). I recall becoming extra-convinced when I spotted an optimization that would have been paradoxical if the correct solution hadn't been correct. I don't remember exactly what it was; I think it had something to do with collapsing nested if() into a single if() based on p vs. (1 - p) for the original door choice.

edit: the more I think about it, the more I suspect that the actual optimization was not randomizing both the door choice and the location of the car, which then allowed simplifying the win logic. If door 0 is always considered the door with the car, then the whole loop body can be collapsed down to:

if (rand() / (RAND_MAX / 3) == 0) noswitch_wins++;

No threat of a paradox as I was thinking before, but a fairly clear statement that the odds of winning by not switching are 1 in 3.
Battling Infectious Diseases in the 20th Century: The Impact of Vaccines
You're doing economic analysis on something that is essentially political. Jailers don't get paid because they are the best, they get paid because they have government contracts - presumably they made the lowest bid for the job. They simply do the minimum to continue the contract and use their gains to lobby for legislation that will lead to more imprisonment or ways to leverage their position as jailer - like creating markets they can monopolize.
Bad food is not more convenient. How is it convenient to be obese? If feces was free, would convenience be a factor? The more people repeat something is convenient as an excuse for doing something that destructively soothes anxiety, won’t make that thing any less garbage than it is. If you want to nourish yourself on garbage, don’t say it’s convenient. Say it’s because you’re anxious, lazy or lost your cultural norms. There’s nothing convienient about being obese.
Anecdotally, I suspect this pattern extends all the way back to childhood. The tendency I've seen, repeatedly, is that misbehavior and horseplay is tolerated in boys, or even encouraged, whereas retribution is swift when little girls step out of line. I've found this tendency in myself, sadly. When my girls misbehave, take stupid risks, boss other kids around, tear around the house and cause general mayhem, I have to consciously skew my responses back to the mean. Not that I think the world would be a better place if we raised everyone up as misbehaving man-children, but at least I want to level the playing field somewhat for my own girls.
The letters quoted in the article are frustrating to read. It doesn't really matter that she was right, people shouldn't have sent those letters even if she was wrong. Especially in probability and statistics, but also in pretty much every area of knowledge, it is common for human beings to hold strong beliefs that are completely wrong or seriously misguided, and we all need to recognize that weakness in ourselves.

I think the world would be a much better place if we all dropped our egos and approached these sorts of disagreements with kindness and benefit of the doubt. Even if we're confident that we know better than the other person, we should approach it as a genuine attempt to understand and clear up the misconception as a way of improving the other person (and be willing to admit that the "misconception" may end up being true after all, as in a case like this). As far as I can think of, condescension is just some obnoxious human habit and doesn't actually provide any value.
Groomed to Death
Some are suspended, for example: https://twitter.com/PIGEONTODAY Would love to know the real numbers. I remember a few articles saying how Twitter mass-suspended 1000s if not millions of these type of info-ops accounts just recently. Further reading: https://en.wikipedia.org/wiki/Information_Operations_(United... focused on US psyops campaings, but the Russians are doing it too, and probably doing it better.
Poorly, IMO. This became clear to me when I had to talk a blind Windows user through installing Red Hat Linux with the Speakup screen reader in early 2001, using Red Hat's text-mode installer. That was when I realized that Windows had actually become more usable with a screen reader than screen-oriented text-mode UIs in a terminal.
I watched that same guy (just discovered his channel through that video) and its hilarious to me that I see him mentioned here and how you have the same reaction to that part like me.

His videos are actually a good resource to the OP.
This video is kinda the exact answer to the queston: https://www.youtube.com/watch?v=70Wcm5c7AF0
Does anyone know how this document relates the the rendering done in the 2016 ratchet and clank game? That game has always astounded me and 8ve never been able to find a deep and comprehensive relation about how the rendering works.
Actually I find choco to be miles better than apt-get. With apt-get I often have to add repos before I can install some app (usually something which fixes some basic part of Linux). This, for me, negates the whole point of having a package manager. What good is it if I have to tell it where to look?
Orchards and markets around the world continue to blatantly dilute Apple's trademark.

"Hey, kid, don't bite that Apple®!"
Death threats, rape threats, releasing targets' private information, threats of violence, stalking, and other such unsavoury behaviour is harassment though. And that's what Gamergate was all about.
It's becoming increasingly clear to me that every time a journalist agrees to any ground rules they have compromised their profession or given the appearance of compromise (which is actually worse than hidden corruption in terms of the effect on public trust).

Conditions on reporting turn reporters ever so slightly from press to publicist. And at that point it's like the cliché about being willing to sleep with someone for millions -- the character has been established and the only thing left is negotiating the price.

Even though the article says it's not done, you have to imagine that some reporters will agree to change a conversation into an "off-the-record" one in exchange for access or a scoop. News orgs live and die by the access they get and if some reporters are willing to prostitute themselves to get it, it puts enormous pressure on the rest.

Conditions on reporting should be treated like doping in sports.

Edit: there is one area in which my framework needs a clarifying remark. A reporter can always voluntarily refuse to identify a source or otherwise protect it and the source can always use electronic or even snail mail methods to preserve their anonymity. My comments above are not intended to mean that reporters must always report every detail of every interaction, only that agreeing to conditions in advance can compromise their integrity and pervert the role of the press generally.

2nd edit: I'm convinced there are areas where granting anonymity is absolutely essential. My above position was clearly a knee-jerk and not well grounded in reality. Thanks HN.
Seems silly to move just because MS bought github. Are there other compelling reasons?
I recently went to the Internet Archive in SF, got a tour of their operations etc. Absolutely amazing place, very forward thinking, and they indeed are very serious about prevent something like the destruction of the Library of Alexandria from happening again.
FF has clearer financing and better aligned projects to the browser through the entities being truly separate between Mozilla and alphabet than chrome has through being a cost center for alphabet. Chrome gets almost no portion of the profits its search bars bring in. Success for a chrome project manager is in supporting alphabet's other projects more than its own market share.

Staying focused on developer tools, being an improved clone of chrome, using rust to achieve better security/speed/clarity, and beating chrome to implementing standards will make them the browser developers do alpha testing on instead of the second platform. That eventually means the most popular browser.

Google's needs push chrome into the wrong place and the wrong priorities just like every vendor provided browser before chrome. I.e. C++ sucks but Alphabet politically has no replacement because their real needs are either server side services (go) or 3rd party developer languages (dart? Something to replace java?) that can't be the foundation of a decent browser.

Chrome is only as successful as it is since Mozilla has a cycle of destroying a fast and debuggable system by trying to bring in the kitchen sink. The very existence of FF is from a group that forced Mozilla to back away from a suite of everything every fringe user wanted that was becoming the worst experience imaginable.
In my opinion most of the distributions are starting from the wrong end. They start with kernel, add package management, decide which services to run, which toolkit to use and then make some utility applications. Sometimes over a few different distributions. This mean not only that it is hard to convince people why they should change things, but that when you made the improvements you want you end up stalling since you haven't actually tackled the things that are lacking.

What you should do is the opposite. They should start with the toolkit, the network infrastructure, the management utilities or something else that would be the use-case. Once you have e.g. a solid toolkit that is attractive to developers and people start making good applications the rest is a matter of time. There is of course a reason why people don't do this, which is because it is hard. But hard is good, it is complexity that will kill you.

This is of course essentially why Android and Chrome OS is successful in their own right.
If you're interested in cutting-edge research SAT solvers, have a look at the annual SAT competition: http://satcompetition.org/ - source code is available for all of them.
The trick to reverse a number is probably awfully slow.

print(int(str(num)[::-1]))

Unless the Python compiler has a huge bigger amount of magic than what I imagine is possible, this code is very slow.

It's not so bad if you run it once, but if you put it inside a thigh loop, the performance would be awful. Never ever use a string to transform a number into another number in any language.

Perhaps you can try to make a post with a benchmark comparing this method and another method that only use integer division (and perhaps other that use floating point division).
AMP is one of the biggest threats to the future of the WWW at the moment. It's an attempt to appify the web on Google's own domain and dictate how you monetize your site. Hand-optimized HTML pages are faster than AMP pages. Here are some links:

Why not uses a decent work function and not have to remember so many chars? I'm keeping track of >20 high complexity passwords that mostly rotate regularly, and my brain is full.

Anyway, it doesn't matter that your password is ygGucg,guc52f when your colleague's is bigbum99.
This is an interesting idea---how hard would it be to do this? It might be as simple as doing k-means on the pixels or some other kind of clustering algorithm, and then fitting a spline curve to each cluster...
Good one haha
Please do post proof of these things. You do realize all of this got investigated by the FBI and they didn't find a single credible threat. Stop listening to what the media tells you about this. That is the whole point of Gamergate.
Why is it that Microsoft are ok with serving traffic from countries under embargo but Google are not? As far as I know Amazon don't follow the embargo like this with AWS traffic either.
Just as a sidenote: Gitlab may no longer be accessible any more from Crimea, Cuba, Iran, North Korea, Sudan, and Syria. From the article:

NOTE to users in Crimea, Cuba, Iran, North Korea, Sudan, and Syria
GitLab.com may not be accessible after the migration to Google.
Google has informed us that there are legal restrictions that are
imposed for those countries. See this U.S. Department of the
Treasury link for more details. At this time, we can only
recommend that you download your code or export relevant
projects as a backup.
70 percent is usually said to be the best concentration as a trade off from lethality to the microorganisms to the time it takes to evaporate.
Considering it's only a problem when updating dependencies and how good and reliable the result is, it's totally worth it.

Worst case in extremely big projects you just add some swap and let it run for a while, the time required is still in the order of tens of minutes.

Compare that to hours long c++ build times.
Integer programming, not linear programming. Linear programming (without the integrality constraint) is in P, so you cannot use it to solve general SAT problems, which are NP-complete (unless a major and highly surprising theoretical breakthrough is found).

The free SAT solvers are very good, and much better than commercial IP solvers at solving problems that are a natural fit for SAT. (Obviously, you can encode any IP as an SAT formula and vice versa, and the IP solvers are better at solving the problems where you actually have meaningful arithmetic.)
Planes don't fit in a shipping container, which probably makes that an expensive one-off.
They had started this move months before Microsoft purchased Github. If you read the linked article one of the biggest reasons is that the GCP implementation of kubernetes and better integration with their CDN they'll be getting a significant performance boost. It's taken this long since they've had to make infrastructure changes along with some code changes to get it better supporting the deployment there.
A lot of companies have been migrating to GCP for pragmatic "it's cheaper" reasons. GitLab in particular had a big booth at Google Next.

This kind of thinking is pervasive in a wide corner of statistics and this is pretty much why machine learning stole its crown, that's why I get to hear quips like "Statistics ? Is that even relevant ?"
That's probably just portion size, which seems to be an American disease.

I'm from the U.K. originally and I regard US portions as typically about 3 or 4 meals.

Further, I've just managed to drop my weight from 188 to 168 lbs just by regarding this as a hard rule, and just generally eating a bit less than I need.
Still pathetically short. Needs to be at least 10 times longer or give general principles rather than listing items.

For instance it doesn't say if I can recycle nuts and bolts. Rather than just adding that to the list though they could say something like "all items primarily (99% of more) made of metal between 50g and 10kg" or whatever their actual criteria are.

Let me just look around the room and see all the items that list doesn't cover: pewter mugs, large steel ball bearings, vinyl film backing paper, screws, middle bits of sellotape, bike brake cables, empty metal epoxy containers, etc...
So that employees don’t try to avoid critical business travel.

When Apple started flying engineers in business class to China, suddenly they got dramatically more likely to go to work out production issues rather than trying to convince management that the issues would work themselves out. A few million dollars in employee travel was immaterial to the increase in production reliability.
That was really great, thanks for sharing!
Yes, this was quintessentially sexist bullshit. It's so ubiquitous that there's a word for it -- mansplaining.

But it's not just about gender. Consider the racism faced by so many Black mathematicians and scientists. And Indians, such as Jagadish Chandra Bose. Even Srinivasa Ramanujan, before his genius was recognized in the UK.

But recall that Black men got human rights in the US before women did. And that corporations also got them before women did. So it's arguable that sexism runs deeper than racism.

On the other hand, I cringe at "smartest woman". What does that really mean? It's like describing some hugely multidimensional thing with a few numbers. All we know is that she did extremely well at whatever tests were used. And we also know that many such tests are culturally biased.
The reality is that nearly all sources, on or off the record, have an agenda. That’s why reporters usually need multiple sources and other proof to run something important.

History is filled with stories that would never have been told if the people who told them weren’t granted anonymity. Going off the record shouldn’t be accepted easily, and some reporters (including some stars at the Times) give anonymity to people in the current administration who are known to lie constantly, which is a terrible practice. But eliminating tools reporters can use to unconver dangerous hidden truths just for the sake of “objectivity,” which is always an illusion, doesn’t make sense to me.
Test code, not sanity
There's no general answer to your question, it depends on the problems. You can find parameter-preserving reductions between some problems, but this isn't always the case.

Also, instead of looking at fixed parameter tractability, it often makes more sense to look at approximation algorithms (if your goal is to optimize something, rather than getting a strict Yes/No answer).
It depends how the check in is used. When I worked in Germany we had time cards and the main purpose was to make sure you worked only 35 hours a week or you got overtime paid. It was more about not trusting management.
