> But the larger point is that the logic of efficiency on the internet will always favor scale—which is to say, platforms—over publishers.

I call bullshit on this one. It's unclear what the author means because they use such a meaningless term in "logic of efficiency", but the last time I looked, it was a lot more financially efficient to set up a website than a print publication. There is nothing at all inevitable about 'the biggest will win' online, as can be evidenced both by the disappearance of several former behmoths, and by the failure of several pre-Internet companies to 'make it big' online despite having unlimited capital to invest.

Maybe, just maybe, the author is referring directly to advertising revenue here, as in "the more popular sites can make more money from advertising, and thus will grow and grow". Of course, that's totally dismissing the fact that many of the 'platforms' being discussed simply offer a far better experience, regardless of what content they offer or how big they already are. Here's a hint for the author and any other publishers reading: there is far greater variation in the packaging, delivery, and experience of content online than there is offline. Take advantage of that. Don't, as we've all been telling you for the last 20 years, just try to replicate your newspaper online: that makes for a horrible experience. Don't try to do advertising in the most obnoxious manner you can get away with; that may have worked in print, but it's been demonstrated pretty categorically now that it fails online.

Or, you know, just carry on regardless, blame platforms for seizing the opportunity that you choose to ignore.

> The transducers used appear to be of the piezo-electric type, those have a fairly high internal resistance and the voltages produced by those devices would be relatively high, the currents correspondingly tiny.

Exactly. These transducers look just like low-cost piezos used for ultrasonic ranging in air (e.g. car parking sensors, alarms, etc.). I have not seen any in that package that would be made for any significant amount of power. High power transducers look quite different.
Twitter is tough because it's so useful and cool in one sense, but the majority of its use is keeping "social media managers" occupied with something the appears to be work.

True enough, and of course a strike from a two-ton vehicle travelling 20 mph faster than one will impart far more force on one's body than a strike of a 180-pound body travelling at 18 mph will impart on the road.

Helmets are nothing more than magical safety hats; they're placebos; they're a triumph of marketing and emotion over reason and sense. If you wear a bicycle helmet, then logically you should wear a driving helmet, a walking helmet and a sleeping helmet.

Statistical significance or not, I have exactly 1 head/brain that has been saved from significant injury thanks to wearing a helmet.

Happy to ride my anecdotal evidence all the way to the bank.
The article is somewhat confusingly worded (the actual paper it links is more clear: http://networks.cs.northwestern.edu/publications/wifm/icnp20...) and I initially thought it was describing something like Microsoft's White Spaces project where devices would automatically transmit over unused spectrum. In reality, the idea is that the devices all automatically select timing relative to an FM Radio Data System transmission and then can infer each other's chosen timing without actually communicating (or they "implicitly communicate" in the words of the paper's author as quoted in the article).
> I can't find a reference with a short Googling, but as I recall helmets only help in a fairly narrow window, something like 18-23 mph or so

I'd really like a citation on that. I'm into motorcycles and while helmet design is different, every motoGP season has plenty of examples of riders tumbling at +100kph and walking away after.
There's one problem with all reports like this - people who have a crash in a helmet and are fine usually don't report anywhere. I flew over the handlebars and hit the edge of a curb with my head - the helmet split in two but I was fine. If I didn't have a helmet on, I would be dead, I am very certain of that. Yet, my accident - like I am sure thousands of other similar - was not reported anywhere. There is no statistic that measures this. And I think it's absolutely vital for producing reports like this.

>A cheesesteak costs $11 in the shop, for example, but DoorDash charged $16.95 for it.

From a customer perspective, this practice feels very disingenuous. The 5.95 should be labeled as part of a delivery fee.

If somehow DoorDash was the first link a user visited after searching for "donut plant", they would need information to decide whether to visit the restaurant or to order online.

The transparent thing to do is to list the 5.95 markup as DoorDash-imposed. That way the user can easily see their choice

Marketing I think was the key here. The Steam Machine needs to appeal to people who are not previously exposed to PC gaming.
People who already play PC games have PCs to play them and hooking up a computer to a television is trivial. Most of them probably know what the Steam Machine is, but if I asked any of my 'XBox' or 'Playstation' friends they wouldn't have the slightest clue what Steam is, let alone the Steam Machine. Why would they? I haven't seen any advertising anywhere.
In combination with the general negative stereotypes about PC gaming (not the least of which comes from the name PC Master Race) I don't see any what that this could catch on.
What strikes me is I hardly ever submit. I mostly comment (outside the tent pissing in). When I do submit I often get surprisingly nice amounts of karma. I just rarely discover something not already been submitted.

OP here. That is an excellent summary. Thank you for that. :-)

The length of these articles always surprises me. I start off with a simple idea: "I just want to explain this data structure."

Imagine a new device to read and record people's thoughts at all time is invented.

That UK surveillance bill is "worse than scary" because according to how its proponents/supporters rationalize it, the logical consequence of this rationalization is that it's perfectly acceptable that all citizens should be permanently hooked to such device if it existed.
Your attack is naively misdirected, I fully support the right of device owners to have a full control of their gadgets including firmware, hardware, software, you name it. But as most users (and we already know this) don't care about these freedoms, for-profit companies don't have an incentive to guarantee them. Especially if it weakens their competitive advantage. Hence my call to support non-profits, like Mozilla.

If the country is so far in the shitter, that they can't pay for good schools for everyone, then allowing only the comparatively mega-rich to pay for mediocre education, while everyone gets nothing won't solve the problem and might even exacerbate it farther.

About 50% of people have an IQ of over 100. That makes them smarter than average. But of course, how smart you are doesn't correlate with how rich your parents are, which has a much bigger impact on your future. In that light, won't it be most fair to test people on their intelligence, then have the state seize everyone's assets once per year and redistribute it proportionally on that?

Unfortunately yes, the compression options and existing parallel code in Oracle means that at the moment IMHO Oracle performs better than PG at that scale.

There are multi petabyte Oracle RAC instances in existence, while on the other hand a 10TB+ PG is very large.

This is a first step in closing that gap. Some form of compression on block level would really help as well. For analytics columnar support will be needed to, and an in-memory option would be nice too.

Modern processed food managed to increase our daily calories intake while decreasing the essential nutrients that we need. Malnutrition is becoming a problem again and worse, for the first time in history you can see overweight kids that are malnourished. And I disagree that the "western diet" has anything to do with our wins against malnutrition.

> a diet lower in fibre and higher in protein, fat, and sugar can equally be found in China and Indonesia

On what basis have you arrived to those conclusions? The normal diet in China and Indonesia is plant based. Yes, they eat a lot of rice, but that rice is much more healthy than the vitamin-fortified substance made out of bleached, white flour that we call bread nowadays.

And don't mistake the food that you can eat in your local Chinese restaurant to what the Chinese are actually eating. For example much of the food promoted in western Chinese restaurants (at least the ones where I've been) is unbelievably greasy and sweet. But guess what, the food being eaten in China is not sweet, sugar and soy sauce being used only sparingly in only some meat-based dishes, but that's not the norm.

Also singling out one nutrient or another is reductionist science and represents everything that's wrong with western nutrition and health-care. Remember cholesterol? That was a fucking fiasco for which the medical community never apologized for. We need more Omega-3? Sure, put some in the supermarket sliced bread. Does our food have so much high-fructose corn syrup or other corn derived substances in it, that we can effectively be called the corn people? Oh, point to the Chinese for also eating sweat stuff. Do the French eat saturated fats and wash it with wine? Call it a paradox.
My wild guess, because we don't have easy ways to create them. Anyway, it's a bit weird considering the extreme relationship between smell, memories and emotions.
In Finland, wearing a helmet while bicycling is required by law, but there aren't any penalties set for not complying. Maybe this appeals to people whose moral includes unconditional law-abiding.
Why not wear it all the time, or at least when travelling? Per minute, the odds of a helmet saving your life are much higher in a car than on a bike.

Seems like the UK has it about right then, where wearing a helmet is encouraged but not compulsory.

I do wear a helmet, even though it's a pain. Reading around I see a lot of sites claiming they are not effective, but it always seems to be secondary effects - like, cars will pass you more closely, or you will ride more riskily due to a false sense of security. Are there any studies on the actual safety record? Intuitively it seems like of course it will be better for you if you fall wearing a helmet - is this true?

> Because describing smells in detail is rarely important?

That may be tautological. Smell describes the chemical composition of air and the substances it carries. I don't think that information is commonly trivial. One could similarly say "we rarely talk about UV radiation because it is unimportant."
I'm hoping someone with more knowledge about Direct3D/DirectX could clarify some things for me.

Flawed was probably the wrong word to use, maybe unrealistic view would have been more appropriate.

"Which of course means nothing regarding whether you would have injured your brain. Our hair, scalps and skulls are remarkably good at protecting our brains."

Even so, I would rather have a cracked helmet than a cracked skull.
The problem is, almost any non-biking helmet is way better than the usual biking-helmets. So no conclusion can be gained from those for biking.
You are free to make the helmet decisions you see best for yourself and loved ones.

For everyone else, I think it's worth contemplating the statistics I linked to from NYC:

* Almost three-quarters of fatal crashes (74%) involved a head injury.
* Nearly all bicyclists who died (97%) were not wearing a helmet.
Facebook has definitely been known to suppress criticism in the past, though. I've shared articles about facebook, on facebook, and they've been removed.

helmets are really useful if you are riding slow too, I was pulling out of a driveway, there was a little bit of black ice that I didn't see, my front wheel went out from me and before I knew it I was down: could not react, one second I was upright, the next second I was on my side and yes, my helmet was cracked by this fall (hit the side of my head on the cement), if I didn't have it it'd have been a much worse day than the very mild headache I got from it.

I really don't understand all these "helmets don't help" folks, having ridden motorcycles and bikes all my life you would not catch me dead without a helmet: a helmet is not an invulnerability cloak but in the end if you fall down and hit your head and you don't have one, you are not going to be in a good place, whether you are going at walking speed or 30mph.

It is very comprehensive but don't you feel like there is too much going on there? Like there are two many sources? Would you think if it is restricted to only a few choice sources, it would be less cluttered? Or do the different definitions give more clarity?
Maybe I could have put that better. I'm trying to say that describing the composition of a smell is rarely important. In the typical case what matters is either that it's the smell of some specific thing (I smell fish and chips - that makes me hungry, I smell fire, I smell gas) or that it's pleasant (you smell nice) or undesirable (you stink). Composition, though, mostly just matters when describing perfume or something.

But yeah this might be a little tautological.

I don't buy the idea that requiring helmets truly reduces the number of riders long term. The kind of person who would not ride their bike because they don't want to wear a helmet is the kind of person who was only going to die for a couple of months anyway. Every dedicated rider I know wears a helmet, required or not.
For the game I have on Steam[1], a logical puzzle game, this just isn't the case. Mac sales are at about 10%, and Linux sales are at ~3%. However, the most outspoken fans of the game, and the ones from whom I get the most nice emails from, are mostly Linux users.

I too would like a citation. Plus calling a bike helmet's foam "flimsy" makes me question your argument. If you've ever removed the outer plastic (which is designed to crumble), you'd know that the foam is extremely tough.

You could likely make the argument that over a certain speed your other body parts will sustain large enough injuries for the bike helmet to not matter, but that's not what you're arguing, you're arguing that the bike helmet itself stops working at an extremely low speed of 23 MpH or above.

I actually Googled this a bit. Cannot find anything on it.

Helmets are generally designed to handle the vertical component of the fall, not your forward velocity.

If your torso hits a solid object at 30mph, there's about ~50% chance you'll rupture your aorta[1]. Hit something like a narrow signpost pole at 30mph and you'll be in a whole world of trouble - I'd post a link to a thread on a motorcycle forum, but it's a bit grisly. Guy survived, but he had to be opened up to treat the internal injuries.

Motorcycle helmets have mostly the same minimal impact requirements of preventing brain injury from the vertical component, but also need plenty of abrasion resistance.

As I once broke my radius flying over the handle bars, I can at least stat for me: it was my broken hand. My head (I was wearing a helmet back then) never came close to the ground as I landed on my hands. Unfortunately one of them failed to stand the forces and broke. Perhaps without a helmet I had driven a bit less crazy and not crashed stupidly.
