> Isn’t it pretty common policy for the US et al to promote pro democracy protests and politicians in other countries?

No, the US have supported and promoted dozens of coups and dictators. The phrase you're looking for is not "pro democracy", it's "aligned with the US interests".

Flying in bumpy weather, the touch screens can be tricky to do precision presses. End up having to balance your finger on the edge of the Garmin and then touch. I can imagine rough seas being a similar issue.
This is what I don't get. If the median income is about ~$1600, how does almost everyone have a $200 phone?

If you assume a phone gets replaced every 3 years -- with service -- that's about $110 per year, or close to 7% of a person's total income.

In the US, median income is ~$32k -- $26k after taxes. If you make the same assumptions, a phone would cost about $580, or close to ~2% of a person's total income.

So it seems like not so big of a deal, especially for something so valuable.

But the teen part is what piqued my interest. India is MUCH younger than the US. Women participate in the workforce at a MUCH lower rate. And household size is MUCH larger. If you factor all of those things together, it means that for like 60% of families with children, you have a single earner with a spouse and 2.9 children. If everyone's got a phone, that's more than 40% of your household income. THAT seems insane.
I’m not even talking about 3rd party clients becoming the main clients. As I said that would be a sign of a much bigger problem than just reduced ability of monetization.

The reasons why they default to lock in are obvious, what I’m saying is that it ultimately benefits their business or has a neutral effect as the type of users to use a 3rd party client isn’t and is probably still using multiple clients (mobile/desktop) and still buys the subscription services.

Discord will always make the most popular client. It’s just how this stuff works. Just like Twitter 95%+ of people go to discord to download the clients. It’s the niche ones on the side that end up getting banned.

It’s not like the advanced features of a freemium model couldn’t be replicated in the client or in Twitters case they can still send ads in the API stream. If the client doesn’t show the ads + is very popular (a key part of the equation) then you can cut them off.
Yesterday I was driving back from Scotland to England, doing 70ish, when we ran into a really heavy thunderstorm. Went from good visibility to almost zero in seconds, and the only thing I could properly see was the crash barrier alongside the lane. I found myself desperately trying to see where the road was, simultaneously trying not to get rear-ended as I slowed up, switch on the rear fog lamps and hazards, max wipers, and select max demist because suddenly the windscreen had fogged up. Was one of those thankfully-rare maximum mental workload moments. Thank god for manual controls and muscle memory. Pretty such I wouldn't have had enough spare attention and/or brainpower left over for operating a touchscreen.
> His basic argument is that if there is an original universe with humans, they might like to simulate their ancestors. And they are likely to run many such simulations, in at least some of which, humans survive. Those survivors, in turn, are also likely to run many such simulations, etc. on down the line.

I read somewhere that the smallest computer to simulate the universe necessarily has the size of the universe.

This would that either the real universe contains much more information (likely more than a few orders of magnitude more so that a trivial part of that Ur-universe can be allocated to simulate our universe), or recursion is not possible.

A way the wealthy can rig the economy:
1) Right now, the richest 10% own 84% of all stocks
2) Public companies take out huge loans in corporate bonds
3) Do stock buy back to raise the price of stock
4) The wealthy shift into privately companies with a bigger precentage of their wealth
5) Workers with their 401k are trapped in public companies, brecause of Accredited Investor laws, they can't invest in private companies.
6) Workers with their 401k are left with only public companies. The companies are forever heldback by servicing that debt.
6) Workers lose out of stock price gains.

I often do mental math like this. However, sometimes it is faster to not split up calculations like this. For instance, in the case of converting 55 mi, it's faster (at least, for me) to just divide 54 by 6, move the decimal, and call it a day.

I've found that calculations are faster when you know when and when not to split calculations like the way you describe (even though at least 80% of the time it's faster to split them up).

> The whole splitting of throttle/steering controls seems a bit odd to me however. I can't imagine a situation where I was at the helm and didn't want the throttle at my command as well.

We lost electricity on our yacht at sea. There are electronic controls for both steering and throttle at the helm but none of them worked for a time. Because the yacht had two screws and the manual throttle control was in the engine room, we were able to steer and navigate the yacht with a man in the engine room with a radio. Traditionally throttle is the responsibility for engineering because there is a lot more going on with a ship than a car throttle.

No. But they allow the little guy to take on the big guy for stealing their invention.

Look at Robert Kearns[0]. He invented the intermittent windshield wiper and demoed it to the “Big Three.” They then took his idea and implemented it themselves. So he sued them and won.

Maybe removing patents would spur innovation, but what then do you do when you’re the little guy?

I would add a major caveat: Xbox controllers don’t have physical feedback the way an actual throttle lever or steering wheel does. See, for example, the endless arguments over whether the Boeing control style (where the position of a control means something) is better or worse than the Airbus style (where the position of a control is just an input).

If I were designing a destroyer control, I would probably make the throttle be some sort of device where the position of the device indicates the throttle state. But I would certainly make the throttle be a single-purpose device that controls nothing else.
Hi,

I accidentally found that my Linux screenshare program is able to send leftover video memory from a previous Windows boot (shut down 5 days ago) over the Internet, showing the private Windows desktop contents of the last logged in user.

This doesn't seem good security-wise for all parts involved.
wheat and corn aren't bitter, still they have natural pesticides called lectins.

Strawberries are sweet still they have tannins which are toxic to humans.

Some green plants taste sweetish or salty, yet they contain oxalates which can damage internal tissues and organs, joints and bones.
Doesn't that imply that it needs to be physically possible to simulate a universe that is as complex as your own universe. I would think that it should be possible to prove that isn't true.
Cordless is awesome!

I've been using it for the past few weeks due to a problem with the Discord electron client spinning up my fans. Using Discord in the terminal fixes the problem (and scores major geek points!)

The main developer of Cordless is super nice. Each issue I've filed has been an absolute pleasure to discuss.
Working is great, but it is not the full memoir. My understanding is that he compiled "Working" so that some important pieces are published in case he doesn't get to finish his memoir, which unfortunately seems somewhat likely.
> But also for all the things that were actually just a case of the intern being inexperienced or too naive it's great for them to go back to this document after three months and see how their understanding changed over time.

Seems like a fantastic exercise, with benefits both ways. In hindsight, this seems so simple and powerful that I wonder whether it's a commonly accepted onboarding exercise for new team members, especially junior ones. If not, it probably should become.
Exactly: Xbox controllers are highly tactile and ergonomically designed so that they can be used effectively without ever having to look at them. In-car touchscreens are a menace, and a design fad that I cannot wait to see pass.
I think that if your metric is not total number of universes, but available quantity of causal interactions, then Bostrom's argument falls apart on probability as well. More stuff can happen in the top level universe, unless you are dedicating more than half the top level universe to simulation, so you are more likely to exist there.
On any other planet the death of the bar industry would be hailed as a victory against alcoholism and date rape.

We still use controllers for most video games over keyboards/mice or touch pads for a good reasons related to how games are played (from a couch vs desk) or the types of games.

As with everything it depends. Throwing a whole category of input under the bus because it failed when we tried in some uses would be short-sighted. Especially as we’ve had touchscreens for less than a few decades.

> inherently inferior / single-system

From the top of my head, maps work better on touchscreens. Navigating document trees. Making elements link together, group them. And there must be hundreds of uses not obvious now because we haven’t tried enough.

Actually I don’t see how any input system would not have some high-stake single system where it’s a perfect fit. That would just be failure of imagination in my opinion.

I find it interesting on HN how inevitably the commenters reach for "Google should disobey the law here" in stories like these. As if megacorps weren't terrifying enough, now we expect them to extrajudiciously decide which laws they think are "just" enough to obey or not? And then simultaneously when it comes to privacy laws (GPDR etc.) we also clutch our pearls about how these companies aren't doing enough!

Don't get me wrong: clearly unjust laws exist and there exist situations where resistance is the moral thing to do. I just find it terrifying how quickly people jump to saying it'd be appropriate for obscenely powerful companies like Google to make up their own legal system and pick and choose which laws apply to them.

Ask HN: May I get some feedback on my new tech channel?
I recently started a YouTube channel called Tony on Tech: http://bit.ly/tonyontech

It's mostly about programming. I was hoping to receive some honest feedback from the community here, in order to improve it.

Friends and family are not going to tell me that it sucks, but maybe it does. :)

Being overly critical of my own output, I do see many flaws myself, but perhaps I'm focusing on things that don't really matter much, instead of things that truly bug people.

So I'd like to ask for your candid thoughts on what you like and what you hate about my videos so far. Also, is there something specific about them that would prevent you from subscribing?

Thank you in advance for your feedback.
I’m surprised that the video RAM doesn’t decay almost instantly when the power shuts off, but not for five days?! From my understanding, the whole computer, including the graphics card, shuts off when you power off a computer. That means that the video RAM is being written to non volatile storage somewhere.

My only guess: Do you have Windows Quick Start turned on? Because that doesn’t shut down the computer all the way; it just puts it in a deep sleep (i.e. the graphics card and its RAM are still powered)
Rough roads too.
That doesn't sound right to me. Imagine I have a proton and an anti proton, and I fire the proton at the anti proton along a perfect straight line. Classically, and ignoring nuclear forces, the proton will end up stationary and the anti proton will instead be launched away, just like a direct collision between pool balls leaving the cue ball stationary.
We don't necessarily have to prove we're in a simulation for those things to be true. Maybe the idea of God and prayer are in fact exactly such a conduit to the people running the simulation. If you believe in the simulation, you have to believe that this idea is completely credible at least.
Recently I've taken up metal machining as a semi-serious hobby. Fully automated CNC machines don't entirely fit my use-cases but for a couple of them LinuxCNC works fine. The primary UI for LinuxCNC is a touchscreen and frankly it's a frustrating limitation.

LCD Touchscreens are just not well suited for that sort of environment. Legit OEM CNC controls are better but honestly every time I use one I can't but feel like that by now we should have figured out something better. Something that is very robust and can stand up well in harsh environments. Something very easy to read, even for folks with poor vision. Something usable while wearing some sorts of thin(ish) gloves. But I've yet to find anything that would be better.
Then you're comparing the sum total of the wealth of many of the richest families to that of one individual person.

The fact that rich people have a lot of money is not really a recent development. But it's the focus on the super rich which is missing the thread.

If housing prices go up, people at the 25th percentile lose and people at the 75th percentile gain. We see the loss for the people at the 25th percentile and recognize it as a problem, but then people are pretending like we can just take the money "back" from the Walton family even though that's not where most of it actually went.

It went to home price appreciation for a bunch of middle aged and retired sociologists and car dealership managers and dental hygienists. If you want them to give it back so the poor aren't so poor then you have to recognize that and thereby identify who it is you really have to fight over that money.
>"that's really weird"

Not really, given that our use of pesticides allows us to feed billions of people worldwide at low cost. Rates of hunger in the developed world are almost non-existent and globally hunger rates are as low as they've ever been and continue to plummet.

Pesticide treated food is safe and healthy too, so we're feeding the world with safe and healthy food. This is a great thing.

It's not surprising at all that people would say all good. There would need to be some catastrophic side effects of pesticide use for people to even think about questioning it.

So far all problems related to pesticides have been far, far outweighed by them giving us the ability to feed billions.
Nah we need to ban barrels that can withstand more than 100 rounds. Then school shooters will need to rebuild their guns during a rampage.

The delivery companies charge the restaurant, up to 35% of the meal value. In addition to the delivery fee that is shown to the end user.

The figure is probably about 30% on average, can be lowered to 25% or 20% for extremely desirable or high volume restaurants that have brand value and demand.

You mean someone like Zubrin [1], who's spent decades designing space propulsion systems? Does it really seem plausible to you that he wouldn't understand conservation of momentum, as used e.g. to derive the rocket equation [2]?

> In this particular case, my impression is that (like the paper's author) you haven't understood the core of the objection: that the non-zero field outside of the gap between the plates is important.

That was the subject of the entire subthread which you just dismissed by instead incorrectly invoking conservation of momentum.

> If you're really determined on this, I can type up a sketch of the full calculation for a pair of circular plates.

Not really, because once you graduate from basic E&M, or just read the work which you decided to criticize without first bothering to read it, you learn about things like plasma screening [3], which (as also pointed out in the subthread which you dismissed) implies that you should not integrate out to infinity.

You have a few open source projects. A good article can be about a problem that you had with one of your projects and how you solved it, or a problem of someone else that was solved with your project. (And a few photos / graphics.) Which one is your more popular project? Which one is your more technical difficult project? Do you have a transcript of your talk that can be transformed into an article?

In Indian cities, for a lot of people involved in the service industry, being in touch with their clientele through phone (often WhatsApp) is a fantastic boon that increases earnings. They don't need the latest and greatest phone, but a smartphone with a data plan is almost surely worth it.
