Part of me agrees. And I also think flying is really cheap, not expensive like people are saying here.

On the other hand, I do want to point out a couple of things. It's crazy to charge for printing a boarding pass. That does not cost money (to a first approximation). Also, substantially all the airlines that charge to check bags will gate check for free. It's just more hassle. So what's really happening is that your seat IS being subsidized -- by the people who check bags at at checkin rather than at the gate.

Have spent the last few years involved with data collection and master data projects. Prior to that, a number of years with manufacturing support systems (more data collection in there as well) In the middle of that was a software startup, and running my own side consulting service.
How is it in the long term? There's historically been a major boom and bust component here, with economic downturns or terror attacks taking a major toll.

What makes me sad is that there are good reasons to throw out information which don't involve denying mathematical truth, yet people, for whatever reason, seem to prefer denial.

What should happen: "I understand that this person has black skin and therefore according to elementary statistics is more likely to be a criminal, but acting on the information would create an unfair double standard that punishes people for crimes they didn't commit, it would help perpetuate a cycle, and it would violate individual human dignity, so I won't."

What actually happens: exactly what parent said. "Oh no! the computer is making uncomfortable findings that we don't like. The computer must be wrong!"

My partner is much shorter than me, and we fly together a lot; the upgrades matter so much more to me due to the room. First class is almost too big for her, but it's so much nicer for me. Delta's economy plus is big enough to be comfy. Other flights are tolerable, but rough, especially at the frequency I travel.

How do you have accidents that often if you're in a wheelchair? Once or twice I can see, but 50 bones is a lot
This may be true in the short term, but I suspect it affects the long term equilibrium (which of course is a moving target).

If the airline didn't have the option to introduce 'basic economy' prices alongside 'economy' ones, they would either reduce the services offered to economy passengers, or charge a slightly higher price than their competitors.
We've had some time for that to happen. So, whose top players in online storage, whose top in secure storage, and did that match your prediction? Im betting against it.
You're arguing against a strawman. The generally reasonable assumption is that you are not living in squalor for the purpose of making the whole calculation meaningless.
I do not understand this. Do other means of transport provide free food? I have traveled cross-country in Greyhound. Never got free food. What is that about airline travel that people want cheap, and still want luxury?

Thank you! I'm honestly not sure which bugs should go with NixOS and which should go to some application or library that I can't figure out. A typical example: since installing a different video card, videos will play in Firefox but not Chrome.
>People wanted cheap and they're getting it.

Did you read the article? Because the entire point of the article is that people aren't actually getting it for cheaper.
A question about the insurance in regards to the accident he had.

He says "Bill had crappy insurance, paying out a maximum of $20,000 for the accident". He says the total bill was $130,000, so is he implying that he himself had to come up with the other $110,000? If that's the case, then why did Bill have insurance at all? I mean, if Bill's insurance would pay $20,000 then Bill himself would have to come up with the $110,000 right? I guess I'm missing something here...
That's true for software that cares about the location of celestial bodies. In those cases use UTC by all means as event markers. That allows you to count calendar days. However to calculate the duration between two dates down to the second you will still first want to convert to TAI to get the correct answer.

Hopefully self-driving or at least largely autonomous cars at an affordable price will make this a no-brainer for everything except trans-oceanic flights. My car has a seat that's more comfortable than any seat I've had on an airplane so far.

I know. The article doesn't say. Maybe it's part of his disease. Some people break bones easily.
Last time I checked, AA didn't charge for getting a seat early: they just charge extra for all the seats that aren't all the way at the back.

The last time I was stuck flying with them the plane wasn't even 1/3rd full. A few people, sitting near the front, were part of their ridiculous set of reward tiers. The rest of us? Packed in the back. After the attendants closed the doors, we got the go ahead to just move to sensible seats of the exact same size and amenities, but that they'd have wanted us to pay extra for.

The airline knew the flight was empty the night before, and so did everyone that went through the check in process and sees all the empty seats they tried to upsell. Is the chance for an extra fee or two beat having the old black lady next to me look at the empty middle of the plane and ask if we were in American Airlines or in the Montgomery Plane company?
If anything flying can be the most dignified way of traveling.

Hmm, I don't think first class on an aircraft has anything on the better ocean liners in the 'dignified' stakes - if you've got the time to burn.
The hollowing out of the middle ground seems to happen in most commoditized markets.

Take meat. Used to be you'd go to the butcher for your meat, and you'd get a reasonably good product, from a butcher who knew where the meat came from, probably even the farmer who reared the meat. That was the way almost everybody got their meat, so the fixed overheads of having a butcher shop was spread over a large customer base.

Move along a couple of decades. Supermarkets, with their more efficient logistics, eat into the meat trade. Butcher shops almost completely disappear. But supermarket meat goes through a longer supply chain with larger suppliers that have the efficiencies of scale to cope with the pricing power supermarkets have. The butcher shops that survive turn into boutiques, where their unique selling proposition is what used to be commonplace: that they know where the meat is coming from and probably know the farmer that reared it.

The market bifurcates into two basic strategies, low price and high quality (see also Porter's Cost Leadership and Differentiation).

The consumer who's willing to pay a little bit more for a little bit more quality ends up having to pay a lot more rather than a little bit more, because the pool of people who could spread the fixed costs of the higher quality is split - most go for the lowest priced product. There's a ratchet effect, where slightly higher quality products are, at the margin, increasingly expensive because there's no scale in that strategy: the more expensive they become the less uptake they get, which means they have less scale, which means they become more expensive.

In some ways it's a collective action problem: what would be a better outcome for a large group of people can't really occur because individual actions can't sustain a stable state change. In other ways - many, if not most economists believe this - it's a better outcome overall, because more people get to use the bargain basement product.

But I think people in the middle are usually worse off in commoditized markets.
Charging for checked luggage means I'm going to bring as much luggage as I possibly can get away with into the main cabin, slowing boarding and unboarding, taking up overhead bin space, etc. What they SHOULD be charging for is carry-ons.

> Someone should write 'an introduction to introductions to category theory'

More like the "Prereqs for an Intro to Category Theory."

The author intended his remark that the work is "for readers with relatively little mathematical background" to mean that his readers aren't assumed to have previous exposure to category theory, not that they have zero math.

He's reiterating the Basic in the title "Basic Category Theory."

Category theory is like the refactoring of a lot of math to express commonalities with a view toward recognition and reuse.

My understanding is that it's the opposite -- function calls expend a cost to save (and later restore) the registers and push the locals onto the stack. Tail recursive functions on the other hand can be implemented as a jump to the top of the function, right after all the stack bookkeeping, and so saves on that expense.

I'm with you. I have issues with the literal class dynamic of airlines regardless. But when I look at how much more I'd be paying per hour for a modestly more comfortable chair, I quickly get to "no way, not ever" territory. Hell, when I had my wisdom teeth out, it was only $400/hr for the general anesthetic and I said no to that. If I ever spend thousands just for my personal comfort, it's going to be on something I end up owning and using for years.
They actually have margins for a few years now. The price of jet fuel has dropped substantially and that drop hasn't been passed on to customers by the major carriers. The last few years have been record years for them.

Link? I have only see this with 32GB RAM.
I'm not aware of any modern US rockets (other than SpaceX) that install COPV tanks inside LO2 fuel tanks. SpaceX is certainly getting a performance gain from the design at the risk of these kind of thermal related failure modes. I hope they figure out how mitigate these failure modes as a COPV exploding inside a LO2 tank is scary! Especially once they start flying humans on-board in 2018 or 2019.
Is CoffeScript still used much? I used it a bit a few years back when I was more interested in webdev and I liked it a lot, but I haven't really heard anything about it for a while. The only CoffeScript code I've seen lately is when I looked into finding the cause of a bug in a package for Atom several months backend back; I don't think I know of anything besides the Atom ecosystem that uses it nowadays, although I might just not be aware of other projects using it.

I understand it is a competitive business but this is the result of consolidation and less competition. Delta, United, American, they're all awful. Who would have thought South West would become the Premier Airline to travel on.

While they continue to reduce capacity, load factors increase. They have everything down to a fine science using Big Data and their Algo's to come up with how many seats to oversell, how many folks they can leave behind, what flights to cancel, etc. They have completely embraced this business model of monetizing every triviality that they can possible get away with. The people traveling are just units, not even customers anymore. Everything is about squeezing every penny they can out of every seat mile and who gives a shit whether you are treated like a human. It's not like you have many options. It's either Shit A, Shit B or Shit C, pick one.

How I look forward to self driving cars that can get 800-1000 miles on a single charge. I can sit in the comfort of my vehicle and read, sight see, rest, or even work as I travel to my destination. I would gladly sit in the car for 10-12 hours instead of flying.
I've looked in to most major brands (Dell, Lenovo, HP, Razor) and can't find any offering with 64GB RAM + discret 4GB CUDA card + 4K resolution + 2 SSD + 1 spinning drive + Linux support.

Helium has a much lower boiling point (~4K vs ~90K) than oxygen, and so at the same temperature would have to be at significantly higher pressure to stay liquid. I'd expect that putting the helium tank inside the oxygen tank would allow the helium tank to be of lighter construction, since it would only have to withstand the difference in pressure between the liquid helium and liquid oxygen. Scaling up the oxygen tank to compensate for lost volume would be lighter due to the squared/cubed law.

I imagine the reason it's not done this way traditionally is that it'd be a pain to fabricate.
A slow solution isn't wrong. Just inefficient.
Oh, I agree. I was gently chiding OP. I think blocking the intersection like that is one of those things that everyone hates, but has also committed at one point or another. Though from his explanation of the situation in another subthread, it sounds like he was in the right after all.

I've read a bit about that. In general, just use what comes with the USB-C device you're using. Longterm, quality issues with cabling will be sorted out. I only have one anecdote with my own equipment. I have an external SSD case[0] that came with a USB-A cable and I simply bought a micro-B to USB-C cable[1] and it worked when I tried it without issue.

What most people seem to want other than ethernet is a HDMI cable (or port) and something like this[2] will work direct from a new MBP. When I was going to buy one, I was going to grab one of those just to keep in my bag.

You're getting a lot of downvotes but no-one is helping you understand why.

> "kindness" in the human world is similar to kindness in the animal world. It translates to weakness, which is why evolution naturally weeds it out of most animals.

Kindness among kin groups translates to stronger groups, so There's a reason that humans are naturally altruistic and punish crimes against their in-group so vigorously: A solitary human outside of civilisation will struggle and probably die. A bunch of humans working together rules the planet.
I'm not sure number of stars on gihub is a good measure of popularity of a language, especially when we're talking about number around 10k. I'm pretty sure Rust has more than 20K users, and Ruby and PHP have both more that 10K. Vast majority of these users though don't look through the C code of their engine and don't star it on github.

It's not quite like that.

Though blaming algorithms for being "biased" is rather strange as well. It seems to me the algorithms do exactly what you'd expect them to: have predictive capabilities about reality.

Of course, there is a problem here. You don't train neural networks with data of people who've committed crimes. You don't have such data. So what data has been used by the engineers to feed to this machine? Data of people who have been convicted of committing a crime, mostly likely.

And now you've constructed a feedback loop. Those pesky blacks are more likely to commit crimes? Always knew it. A man has been murdered and there are 2 suspects, one white and one black? Why even bother investigating the white guy, we already knew it was the black one. Holy cow, 1 year with the new system and black crime has increased by 50%! Always knew it. Better keep the system in place to save everyone from those pesky blacks.

Oh, the irony.
> I think the key to having more people achieve a good retirement is to reduce the cost of existing as much as possible. That means zero property tax for individuals or at least non-working people. One should be able to buy some property, put a dwelling on it and grow a garden if they choose without any ongoing costs. That would be an idea retirement for some, and the rest can upgrade from there by having more money. But instead we created a society where there are recurring costs to existence and people struggling the most to achieve independence pay the highest tax rates.

Traditionally this existed as parents moving in with their adult children. Half of the bargain would be babysitting your grand kids. In exchange you got a roof over your head, food, and the joy of seeing your grandkids on a daily basis.

> All homicides in Mexico don't add up to 250k per decade. And at most half of the total is drug-related.

Homicides were 20,525 in 2015 by official government numbers [1]. Same in 2014 (see same report). Far more than half are crime related, which in Mexico often means it can be connected to drug trade or other activities of the cartels (extortion, people trafficking, etc). This has been a 10 years drug war, and official numbers under-report deaths dramatically, since executions by army and police are rarely counted as homicides and many other killings by drug cartels end up never being investigated and reported as "missing person" cases. This also mostly affects non-criminals, unlike in the US.

Say it is 20,000 a year for 10 years, which seems reasonable based on the figure in the second page of the report. That adds to 200,000 with only the official numbers, only counting homicides classified as such. Add all the missing person numbers (which sure, might partly count displaced migrants, but just as often means dead and thrown in a clandestine burial) and 250k sounds conservative.

I believe the US has a similar mortality rate of car crashes to Mexico, and I can tell you, having lived in both places, that the social side-effects are not even in the same ballpark. This is not a "terror attacks in developed nations kill a few hundred a year, cars kills tens of thousands, we over-react to the first!" kind of argument (which is an argument I agree with), this is a "we have a death toll from the war on drugs that puts us as the 4th bloodiest conflict currently ongoing in the world in absolute numbers[2]".

See also: http://www.insightcrime.org/news-briefs/6062-mexico-victimiz...

From that article: "Based on the survey results, INEGI estimated that in 10.7 million households in Mexico (33.9 percent of the total) at least one member of the household was the victim of crime in 2013, or some 22.5 million people -- a rate of 28,224 victims per 100,000 residents". I don't think you can quite understand what it is like to know that in a given year, almost 1/3rd of the population will have to deal directly with crime happening to them. Even if it is mostly theft or extortion, rather than outright murder.
