I think you may be assuming that veins are rigid, so can create suction at the top, like a siphon, as blood flows back down the neck. If that were true, it would not take much work to move blood through the neck and head. Maybe you are thinking the veins could be braced against surrounding bone structures, to be held open against such suction.

Unfortunately, that cannot work. All the capillaries in the head and brain would also need to be rigid, and strong enough to hold back that much suction. There's no way around actually doing the work to pump the blood up there, and letting it drain back down.

But that isn't a slam-dunk for extreme blood pressure. We have plenty of examples of valves in veins to help get blood back from lower extremities. A little musculature around a pair of such valves on an artery could easily develop into a secondary heart, and a series of them could eliminate much of the need for the actual heart to supply all the pressure, or for the aorta to resist it.

It is not unreasonable to expect to find novel adaptations in an extreme body plan. Supporting the idea in the absence of fossil evidence is hard, even when such a novelty would eliminate the need for such a novelty as absurdly high blood pressure. Biologists resist suggestion of soft -tissue novelties much more than suggestion of physico- mechanical absurdities because they are, after all, biologists, not engineers.

I wasn't making a specific argument about Gutfeld though. The broader context is that it's favoring partisan sources and messages.

That's an outcome.

By explaining why that outcome is reasonable and giving a list of valid claims to support it, it does not address the stated problem which is the fact that this search engine presents a slanted view of American politics.

Why is it ok to have this kind of search result? We all don't owe our media corporations any kind of loyalty, and we all know that they have an interest in a particular point of view.

I'd think that in this kind of situation we are all best served by knowing what the folks at CNN are saying and also what the folks at Fox are saying (not those two specifically, but as stand-ins for multiple points of view).

Not if you want to limit your eating window, which is a great way to make your body burn its fat reserves.
Losing weight and gaining weight is simple physics.

Nothing about the body is simple.

- There is a virus that studies suggest (show correlation) increase weight gain [1]

- There is a study that shows water in != water out (unfortunately my googlefu is failing me though).

- Empirical: I've lost weight eating 900 calories/day and I've lost weight eating 3500 calories/day with the same level of exercise. The difference was the 900 were carbs, the 3500 was >90% protein.

I don't see your point. People still hate each other due to trivialities, we just mostly stopped killing each other.

If you wonder how we solved racism, we did it with simple and blunt rules everyone can follow such as "don¨t say the n-word" or "don't say that whites are better than blacks". People are still racist, but simple rules like that makes it harder to rile up a mob enough to burn down a black neighborhood (I know it happened in Tulsa, that is why I used it as an example since it probably wouldn't happen today).
Diets fail because people make them something you do rather than something you are. You can stop a diet. A life change is permanent.

I’m down 42 pounds from my max weight and am at a healthy bmi. I too eat whatever I want I just eat less of it. It stuck when I stopped calling it a diet. It is just how I live now. I feel tons better and my knees stopped hating me.
ah yes spot reduction, doing crunches will not remove the fat on your stomach. If anything it'll make your stomach bigger with muscle gains!
Yes, that's very much my point!

By extension, it excludes reasoning about weight loss in terms of conservation of mass/energy.
It’s not true if you’re playing for fun. If I go to a pre-release it’s a walk in the park. When I was playing competitive MtG, it was draining and I would be eating power bars every hour or so and still lose weight.

Except Ito wasn’t the only faculty member taking money from Epstein, and the Media lab wasn’t the only department. The thank-you letter to Epstein that Reif signed was for money Epstein gave to support Seth Lloyd — a professor in mechanical engineering and physics — and the earliest known money from Epstein after his conviction. The ‘if not for Ito’ reading doesn’t make sense.
> Sports are part of a traditional old-school liberal arts education.

A traditional, old-school liberal arts education consists of exactly the seven liberal arts, divided into the trivium ([Latin] grammar, logic, and rhetoric) followed by the quadrivium (arithmetic, geometry, theory of music, and astronomy.)

The slightly less old-school version takes the old trivium deemphasizes formal logic, and adds Greek, history, moral philosophy, and poetry.

Tesla Predicted Smartphones in 1926
This is somewhat easy to do if you have a roof-rack or somewhere similar on your vehicle to mount a small-ish panel, and you are handy and understand your vehicle's electrical system (though this may be tough with newer models since everything isn't controlled by simple switches any longer).

Basically, mount your panel, and install a block diode if it doesn't already have one, then run the wires (positive and negative) to your battery to keep it charged.

Then, all you need to do is hook up a switch to your blower motor inside the vehicle, along with a simple speed controller (for this, it's best to use a cheap 12 vdc PWM controller - don't try to use the "low speed" resistor if your car uses a resistor pack, as it might not keep it cool enough) - so you can turn it off and on, and control the speed of the fan - while the car is parked and "off" (no-key).

Park it in the sun (of course), set the vent controls to allow air in from the outside (hopefully it stays this way when the car shuts down - if not, you'll have to figure out a way around that), crack your windows slightly (1/4-1/2 inch), then shut off the car. Flip the switch and set the speed control for the fan to something "low" - the fan should run, but not at hurricane speed.

Then get out and close/lock the doors. Air will be drawn in from the cooler outside, blown into the cabin, and exhausted out the windows.

The battery will stay charged from the solar panel.

If you are concerned about the battery being run down when the sun sets, then:

1. You can optionally use a separate battery to the fan, with a blocking diode to keep the fan from using energy from the car's battery.

2. Or you can add a thermostat to detect and only run when the sun is beating down hot (this could be in addition to the PWM control - so the fan doesn't run all the time, only when the cabin gets too hot).

3. Add a photoelectric switch to disconnect the fan from the battery, when the sun goes down.

4. A simple way would be by just wiring a standard Bosch SPST automotive relay (the coil) in series with the panel, and the fan across the contacts - when the sun goes down, the relay would open up, and shut off the fan.

Note that this car ventilation mod does not require an Arduino, so you might not become popular or upvoted on the tubes, but your car might be cooler in the summer...
What's the company you work for?
Nailed it.

I also got a chance to work in such an organization in the 00's, where dev and ops closely aligned with each other's work to produce truly reliable, repeatable, fast, quality products, often. It was fantastic. Nobody would say "oh but you can't do that, that's not Infrastructure as Code!" They would say, "what can we all do to make this better?"
When every scholarly piece of research cites those as reasons for homelessness (along with the price of housing), then yes, it's easy to repeat what the experts have already said.
If you eat 500 calories and burn 600 calories, the energy has to come from somewhere. So in a sense it is actually a pretty simple physics problem.

It gets tricky because calculating calorie consumption is really hard (how much of what you ate was actually turned into energy) and calculating calorie expenditure is probably even harder.

>Nearly half of millennials said the biggest mistake they made with student loans is thinking their starting salaries would cover their monthly payments, a new study shows

Nearly half of millennials said the biggest mistake they made with student loans is listening to the recruiters who said their salaries would easily cover their monthly payments.

My snarky ass editorializing of the title aside, I would be curious how much is from genuine misconception/underestimating payments, or are they being encouraged/misinformed by those who want to keep the seats filled in their schools?
I'd say this depends of the complexity of the I/O system.

This was the original claim, which you supported:

'Parsing Lisp in Lisp is so easy because it’s free.'

The example you were pointing to is explicitly calling a parsing engine of Racket via 'read-syntax'. Actually more complicated than the usual s-expression reader - which does only read s-expressions, but has no further idea about Scheme syntax.

Check the usual Scheme report / Racket documentation for the definition of Scheme syntax, syntax objects and its extension mechanisms (macros, ...). I'd say the whole thing is non-trivial. There is a grammar of Scheme, but it is not fixed, because there are extension mechanisms, which make parsing challenging.

It's 'free' because it's a provided language facility - but not free in terms of complexity of the concepts to understand.

And no, the syntax of s-expressions (-> data) is not the syntax of Lisp. It's just the syntax of s-expressions. Search the Scheme report for 'syntax'...
Well the majority of the science was done by the middle aged men and woman you are now attacking in your comment. What does she have to add, that they have not been continuously stating for >40 years? The club of Rome report is almost 50 years old now (https://en.wikipedia.org/wiki/The_Limits_to_Growth).
> “dad weight”, you gain weight because you don’t get good sleep after having a kid.

No this is because you've had a baby and don't need to be in good shape to keep or sleep with your partner, so you stop going to the gym, eating well, doing exercise etc. Applies to both sexes.
Agreed, the rider would be less likely to fall off, and would have better visibility.
The article implies that the US intelligence community has said there are back-doors; here's what I was referring to:

What’s not absorbed by your digestive system is not considered “in” which why cellulose for example is not counted as calories. https://en.m.wikipedia.org/wiki/Atwater_system

However, you also absorb and excrete more than just energy calcium for example.
I think you're missing the point of the "meme". The point of the meme is that human bodies are not closed systems, and that the way to regulate the state of the system is to regulate what goes into and out of the system (if bodies were closed systems, there wouldn't be inputs or outputs to regulate.)

The point is that the body adapts to burn more or fewer calories depending on how much you eat. Restricting calories can possibly have the side effect of just lowering your metabolism, rather than just losing weight.
I'd argue that people who read 4 or 5 books on programming don't know much about anything either when they first start out.

In fact, I'd argue that a graduate knows much more than most people think. The problem is that it's usually general knowledge that doesn't apply to some specific framework that 90% of developers use. It's all abstracted away to learning X framework.
Or people who are naturally fit with no effort vs. people who aren't willing to massively restrict their diet and live in discomfort for the rest of their lives since the body permanently adapts to expecting a certain amount of food: https://www.thecut.com/2016/05/weight-loss-metabolism-slows-...

1. the US average is not meaningful in Texas

2. $75 for an oil change including filter and synthetic oil is not an overcharge

3. I am more than able to change the oil on my vehicle myself, just as I'm able to adjust the derailleur cables on my bicycle and mow and edge my own lawn. Ask yourself whether you are overcharging yourself to do these things

I can put all of my bicycles on the stand and replace frayed cables and crimp aglets onto the ends, or I can put every single bicycle I own into the back of the truck and have the bike shop do it for me. It's not a question of whether I've improved myself, it's not a Don Sharp "Under the Hood" question whether I respect the work involved. It's a time and annoyance issue best left to people who earn less than I do.

If I'm dissatisfied with the pull on badly-run brake and shifting cables, or badly installed cable housings, I can complain and have them replaced. If the mistake is my own, I am left with a dilemma: How important is it to me, in terms of blood and treasure, to fix the problem myself? This creates a schism in my thinking about priorities and commitments.

Bike shops do not have this problem. They source parts in large quantities, they perform these tasks with regularity, and the customer is always right when he says "I want the featherweight Shimano DA cable, just get it from QBP or whomever, but do it."
Ask HN: Is quantum computing likely in the next 20 years?
A colleague recently asked my thoughts on quantum computing. I know little about the subject but I responded that it seemed that it is still a long way off becoming viable outside of CS theorists and academic labs, based on my cursory readings over the past few yesrs.

What does the HN community think? Is quantum computing still a long way off? And when will we know that quantum computing has actually arrived?
My wife has ADHD and to get through her university degree she had to learn time and attention management. The thing is though, these strategies would actually be immensely valuable to anyone, but because most us don’t need them, we don’t learn them. As a result of all that hard work she turned out to be a much better student than the majority of her peers.

Those skills transferred almost seamlessly into project and task management.

There are a lot of stories like that, where that problematic past you talk about, give people some really valuable skills. Of course a lot of people don’t succeed in their struggle, and I think most people who do, would still rather be “normal”, but you shouldn’t disqualify people because they’ve had to struggle.

I’ve been thinking about this for a while. I ride NICE bus here on LI, NY (a dumpster fire of a bus service/management, but that’s another story). We have two lines that terminate in my town, and within 5 blocks of the start is a big hill. Not feeling like paying 2.75 for the ride up the hill, I imagined how great the PR would be if NICE could make rides within the city free.

(No clue how you would manage that situation—get on for in-town, but stay for extra miles. But it’s my imagination, so whatevers).

When I lived in SF, once in a while I’d hop on the Cable Cars for a free ride.

My town has a $2/free-senior citizen bus, too. But it runs only a few trips a day, and it’s a one-way circuit.

Free in-town public transport is a big idea I wish was realistic for more places.
> people died, a lot

As always, as many people die, as are born :).

We got better at hiding the fact - by letting people die in hospitals, in homes for elderly (western world) just so it's out of sight and we are less reminded of death. On average, people live longer, yet it's not that they die "less".
