This is about appetite. Skinny people have a smaller appetite than overweight people.

Considering that the US average for miles driven per year is in the 16k range, I'd say you were an anomaly (25k miles/year) and that applying your specific usage pattern to judge other drivers changing oil twice a year is not useful.

Edit: also, if you are paying $75 for an oil change you are being over-charged and should learn to change it yourself instead.

I lost 10kg in 90 days. I didn't follow any fancy diet. Just counted calories.

Yes, I know, I know it's flawed, but many of you are reasoning your way into eating what you want and the problem is discipline.

I ate ice cream along the way. I too ate what I wanted, but I just tracked everything (I used lose it) and never overate my budget.

The first diet that ever really worked. Nothing can replace discipline.

Advertising didn't ruin billboards, because they had no other reason to exist. Some of the others would be very different without advertising - radio and TV definitely, newspapers and magazines to lesser degrees. Even the "ad free" sites are not entirely free of advertising. For example, right here. How much of YC's money comes from investing in companies that depend on advertising for their revenue, and how much of that money they're investing comes from people who made their fortunes that way?

Yes, advertising might be a net negative, but it's not a pure negative. It is important to help sellers connect with buyers. In a lot of ways it's like finance, which can also help lubricate the gears of commerce, but both it and advertising should be adjuncts to commerce. They shouldn't be these swollen behemoths that dwarf other industries. IMO taxes are the way to account for their externalities, and also reduce them to their economically optimal levels.
The productivity is higher because you have one of the highest concentrations in the world of big companies at the top of the field employing the best people and most resources. Not rocket science.

This has nothing to do with people that think they deserve to work there (which I frankly don't get what the big deal is, you're not a teenager scoping out the best colleges anymore) but obviously the marketplace disagrees.
Exactly correct. But valuing education is now as politicized as hurricane forecasts.

This is because education level is a major factor in voting patterns. So conservative pundits have made open war on it, to the nations serious detriment. They could instead work to lower the price of education but that is absolutely not the agenda for the same reasons.

It's not entirely unprecedented, universities have been called communist incubators for decades. What is new is the shift in portrayal from communist to being a bad investment (but with no intention of fixing that). Also new is the willingness to cast off the nations future for political gain which previous conservatives apparently were not willing to do.

There are similar patterns for climate change, guns and renewable energy.

> If I could go to a space where I'm immersed in code, data, paint or sound and could interact with it to create, I'd be all sold on VR.

I'm not saying that wouldn't be cool, but using coding as an example, how much more immersed are you going to be coding in VR as opposed to going into a quite room where no one will disturb you with multiple monitors. The extra immersion is cool, but I don't being slightly more immersed in the way VR provides will lead to any sort of technological revolution.

> But AR? What can I get with it that I can't with a phone?

It's not about getting new information, it's about not needing the phone to provide that information. Think about a surgeon having the parts of heart overlaid on the body while doing surgery. Think about firefighters having the blueprints of the building they are entering in front of their eyes.

The value of AR isn't providing new information, it provides an alternative to relying on memory for that information.
Generally when people refer to 3D they mean each eye receiving different images as opposed to 3D models being shown on a 2D screen.
> That works for Wikipedia

Wikipedia doesn't do any original reporting, it (essentially) uses volunteer work to aggregate/summarize original research that other people have done. That original research has to get paid for. Or in other words, if all journalism ceases to exist, suddenly Wikipedia won't be able to function either.

> it works for NPR

NPR is also supported by advertising in a big way, we've all just sort of collectively agreed not to call it that. Technically NPR has "underwriters" and not "advertisers", and they run "underwriting segments" instead of "ads", but apart from a couple of FCC rules mandating stricter truth laws than normal ads, there's not really any difference.

> as on Twitch

The vast majority of Twitch broadcasters do not earn enough to make a living, and the ones who do generally get that way by being flashy, vapid and obnoxious enough to attract a cult following. I don't want this model to carry over to journalism.

In conclusion, I don't think your comment offers any real evidence for a possible "third way" in journalism.
Not sure where I saw it, but it was in East Germany most likely (AFD, etc).

But beyond that the amount of such voices I wittnessed in my feeds also isn't too small and I neither followed Greta Thunberg nor do I have many environmentalists in my feeds.

Literally every news article daring to mentioning her had 40-50+ "critical" voices with a perceived majority of men that could have been her father.

So all of what I say here is obviously very subjective and I am convinced that you are right, when you speak of a loud minority. What fascinated me is how middle aged men go and under their real name rant about a 16 year old girl and still feel like they are doing the right thing. And I don't mean trolls, I mean guys that really do think this is what they need to do.

Myself I didn't really deal with Greta Thunberg. I think it is nice that she creates attention for this important topic, espcially among audiences who wouldn't be reached by pure scientific publications, but personally I am not that interested in what she says, because her points are mostly moral and ethical and I agree with the general idea that we need to drastically change things even if it hurts.
True. I'd also add that it's easier to be vegan in Israel since vegetables are big part of the local cuisine and Israelis love falafel, hummus, etc. In Tel Aviv there's a falafel joint every few blocks. (good falafel, not like most falafel in the US)

You shouldn't need to make $150k to get by as a welder. In any sensible society a person who knows how to do something useful like weld should be able to muddle along. Some of my friends from high school in Oklahoma became oil field welders in the 90s. They made good money, bought houses and raised children early in life. It seems like a square deal to me. Of course, that was possible because houses in Oklahoma were plentiful and cheap and the public schools were good and so forth. You know, the way civil society is supposed to work.

While this is probably mostly true, there is good science indicating that certain hormonal portfolios "hold" onto calories better than others. There is a reason power lifters are spiking insulin post workout, people are taking steroids, and medical conditions can make you fat.

If my mother wants to cut weight, I'm telling her this. If an athlete has to make weight for a fight, this is a stupid way of thinking. At the end of the day, calories in calories out is an objectively good rule of thumb. It's not the be all end all rule though.

Advertising starts out okay. But the endpoint is all ads, no content. And the content is very low quality.

An excellent ongoing example is Cable TV. Content is now about 50 % of the time. When a long string of ads are completed, then characters and other bugs and gizmos walk out onto the screen, on top of the content, obscuring the content, sometimes even important plot elements.

Or remember how BYTE magazine gradually became pregnant with ads, then eventually became what I would call the forerunner of Computer Shopper. All ads, no content.

And the web. Sites now have more ads than content. Especially some "news" sites. And the ads are obnoxious. Pop up, flashing, blinking, jumping, scrolling, in your face, making the content impossible to read.

I was an admin (wiz) on various MUDs and MUSHs many, many years ago, and of course an avid user. The mix of programming, creativity, and camaraderie was sometimes very special. Maybe my recollections are clouded by nostalgia, but it sometimes felt like a hacker fantasy, coding, role-playing, and working together for good (fun). I wish I could recapture that feeling, I wish there were time for it, and I wish there were some way it would do good in real life.

I can't contribute anything directly about this bot, but I'm glad to see MUDs are still being studied. I feel like I never saw the full potential of what they could do for society. Some of the social interactions were much more rewarding than anything I have experienced on so-called "social" media.
> Some people are naturally skinny and others put on weight quickly. This is already well known and shows that there are complex genetic inputs as well as other ones. We have to discover what those are. So saying it’s just calories in/out, stupid... nope!

I never really understood why this was always a catch-all trump card. So you can't gain/lose weight as easily as others. In my mind that just means you need to work harder rather than shrug your shoulders and say "nothing to be done". Specifically its people doing this that never look into their diet or are willing to change any of their habits.

Slightly related but Carol Dweck's growth mindset for education is literally this, but the difference is in people who believe they can't get in better shape and people that can.
> But it could not be simpler or easier to bypass Google.

My point was that your run-of-the-mill user doesn't do this. It is easy to bypass, but how many people actually do it? You're just saying to me that people should become power users or just accept that they're victims of manipulative advertising.

Anyway, the rent they're charging is other products masquerading under Bootcamp's popular name. They're essentially charging Bootcamp rent so that "fraudsters" can't eat up the top positions in search results for your product. Grocery stores don't let a Cheerios knock-off named Cheerio-os sit on the end-caps because they paid more than Cheerios. If I go to my grocery store and ask for Cheerios, they'll take me to it - not Cheerio-os because they paid more for me to find them.

It sounds like a racket to me. You can pay google to keep your company at the top of the search results, or they can break your kneecaps by making you hard to find.

And why is rent-seeking behavior something that we want in a search engine we are supposed use to find relevant information?
Depends on who your target market is.
You can draw the cards in a random order by using the output of an accumulator fed to a block cipher as an index. The fixed output size of a block cipher does entail extra work in filtering numbers outside the range you'd like, just as you would with an LFSR. (as a direct power of 2, you could directly use an LFSR or some ECB-mode block ciphers as if it were format-preserving, but that is "coincidence").

You can produce an exact random permutation with a Feistel network for any number, in this case selecting every number between 0 and 2^64 exactly once, with no appreciable space requirements.

procedure feistel(input) {
result = input;
h = 2<<32;
for (let i = 0; i < 8; i++) {
l = (input / h)|0;
r = input % h;
temp = r;
fn = (r + i) % h;
r = (l + fn) % h;
l = temp;
result = h * l + r;
}

return result;
}
For the record, Stephenson's skateboard smartwheels used a bunch of little pads mounted on telescoping spokes instead of a solid wheel. The board had a terrain-scanning laser mounted in the nose, and pulled the spokes in and out so that the wheel was perfectly shaped for the contours of whatever it was about to roll over; you can ride a smartwheel board down stairs as smoothly as you would a ramp. But they were still very much wheels. There was no walking motion involved.

One of my first job’s after hishschool was Aluminum TIG and MIG welding. I learned to weld throughout highschool and was hired because of the reputation my school had for teaching welding.

Unfortunately, I think most of the trade skills are no longer taught at that school.

My welding career was only for a couple years, but during that time I focused on improving my TIG skillsets and was able to move into the number two postion at a high end shop that manufactured Aluminum wakeboard and fishing towers (Samson Sports).

The welding quality was superb, and every inch was looked over for visual and structual perfection. Needless to say, the pay still wasn’t that great.
This isn't a disagreement, but I was thinking the other day that the most widespread practical (non entertainment) AR app has got to be backup cameras and displays in cars.

Modern ones show both the actual live view + a composited on graphic of where your current backup line will take you based on the tire angle, etc.
Generally Ive found tight feedback loops to be incredibly productive. Whether its for product, release, design, development. Having the ability to make modifications with feedback from customers, systems, business partners and colleagues changes everything.
Same, though I'd phrase it differently.

I spent 3 months working on an AR project on the Magic Leap (the best funded AR startup, I think?). My conclusion was that the hardware just isn't there yet.

VR tech feels impressive because the hardware works well. AR tech, on the other hand, still feels very much like a prototype, and far from real production use. Some of the main deal-breaker issues are heat, discomfort, dizziness, and software instability (I wrote more about the specific issues I encountered with the Magic Leap in a past thread [1]). To me it felt significantly worse than the Oculus Rift Development Kit 2 (the second public release of a VR device back in 2014). Back then when I got that version because I was super hyped for VR, I thought "Woah, clearly needs more work but this is amazing". With AR, my experience thus far has sadly been "Oh, this is it?".

A lot of it is presumably because AR is much harder to do well. A very simplified way of thinking of VR is basically it's a screen close to your face that can track its own pitch/yaw/roll/small amounts of movement and redraw accordingly. This is tricky, but totally doable (and thus, it was done). Smartphones have basically been able to do most of this for years (not so much the movement, but that's also a pretty new thing in VR).

AR actually has to interact with the real world. If you have a virtual image anchored to, say, a pendulum, that's fairly non-trivial computation-wise to recalculate without prior knowledge of the pendulum's movements. It's basically object detection which ML models can do fairly well, but they do it with latency. And when the latency is in something your brain is trying to process as the real world, it's nauseating. Add on the fact that it takes a lot of energy to do inference, and that AR devices need to be standalone devices that can be taken anywhere by themselves, and you also have a serious heat problem where the compute needed to constantly analyze the real world means you just have a hot brick on your head or in your pocket.

I think it's going to take a lot more time to get it right. It feels like a hard enough problem that I think the first truly production-grade AR device will have to come from one of the big companies, possibly Microsoft with HoloLens.

Of course, I write all this with the definition of AR as "something you wear on your head that overlays your full field-of-view with virtual graphics". Other forms of AR like Snapchat filters or camera overlays are probably less challenging.

That's like saying the better off developers are senior software architects or consultants.

I've a 2013 MacBook Pro and am in a market for a new laptop. Please suggest a higher quality product. Even just matching this product, is a challenge - keyboard, trackpad, retina display, battery life, operating system (Windows is spyware, Linux hardly works on laptops). Not to mention that e.g. Apple's ecosystem (iCloud, iPhone, MacBooks, ...) are way better integrated than anything else. Privacy advantages (iPhone is literally the only sensible option for a privacy-oriented consumer). I could go on.

Look. I wish any other company would step up and make anything even remotely similar. But they just keep dropping the ball. Closest are probably XPS laptops, but (1) they run inferior OSs, (2) the hardware is probably subtly inferior (e.g. trackpad, battery life, heating & ventilation, plastic chassis (LOL), weight, ...), so for the price I might just buy Apple again (or stay with my old laptop, which, contrary to your comment, still works very well - though admittedly I don't have to use XCode).
