Arithmetic coding is a standard compression technique. It uses less bits for more frequent characters (think Huffman code, even though they are not the same).

This one makes arithmetic coding "adaptive". Consider this. The rough frequency of `e' in English is about 50%. But if you just seen this partial sentence "I am going to th", the probability/frequency of `e' skyrockets to, say, 98%. In standard arithmetic coding scheme, you would still parametrize you encoder with 50% to encode the next "e" despite it's very likely (~98%) that "e" is the next character (you are using more bits than you need in this case), while with the help of a neural network, the frequency becomes adaptive.
Anecdata says that Japanese cars are the most reliable ones. (Old) Toyotas in Africa are a must. They endure and can be repaired in a local car workshop.
Many electric razors (at last in Germany) consists of a head (which is a bit plastic and the blades) and separate handle (which has the electric parts). So reusing the handles is just fine as they don't get into contact with any cut (through desinfect them anyway).

For classical razors you could have a culture of getting a high quality one when you start needing it and then keep it for a lifetime if possible (through you have to sharpen it from time to time).
That's the way to go. Great project. Hope to see a lot more innovation coming out of DIY projects. Great job!!!
One more reason why we badly need FOSS+H phones :)
Interesting project btw. And really good battery life, although in idle, considering the RPis aren't certainly optimized for low consumption like other boards are.
Hawthorne Effect:

https://en.wikipedia.org/wiki/Hawthorne_effect

In short iirc at first they thought the changes they were making was what caused the increase in productivity but then they found out that the people worked harder because they were being observed and felt special.
Reddit has gone through many changes both in the product and the organization.. I feel like its initial purpose/mission has been lost in the way that it was intended as an open space to share things. I do absolutely hate the redesign and hate having to type the URL out.. the redesign is more tedious and eats up data like mad
Like a lot of such mechanisms this does have a flaw that it's not really useful for the most vulnerable people. When someone like me gets screwed by a landlord (back before I bought somewhere outright) they can invoke the protection mechanism and even threaten to go to court, but when somebody who struggles every month to find rent gets screwed this way they're focused on how they'll afford food, they don't have the time or money to fight.

Historically a lot of those people rented from their local government and so not mistreating them was a matter of government policy, subject to oversight by voters like me who certainly do have time and money. But these days it's likely to be whoever has the cheapest private rent offers. Local governments have been defunded so much they may not even have anybody left to even enforce licensing rules, so crooks who shouldn't even legally be letting properties can steal with impunity.

Courts try to help. If you get to court. But most of these vulnerable people never will.
Reddit’s redesign is ok, and I can use it when I have to, but it’s worse in every way than the old version.

Nir Sofer: http://nirsoft.net/about_nirsoft_freeware.html

“In the beginning, NirSoft was hosted in some "free" Web hosting services like Tripod and ‪multiservers.com‬
Unfortunately, these "free" Web sites produced a fair amount of annoying popup ads and some of them even tried to install unwanted Spywares on the computer of the site visitors. Also, after my site became pretty popular, they disabled my hosting account because I used too much resources on their server.
In August 2004, after suffering from all these free services, I decided to purchase a domain for my site (‪nirsoft.net‬) and host it in a non-free hosting service, in order make my Web site more reliable, friendly and secured. In the days that I started with ‪nirsoft.net‬ domain, my site was already popular more than an average Web site, with more than 90,000 unique visitors and 1.5 million hits in a month”
Judging by the last couple sentences, I think they’re posting on behalf of the residents, who wouldn’t get much help from the company.
The game also has an interesting history:

"Prior to working at Atari, Alcorn [the engineer who created Pong] had no experience with video games. To acclimate Alcorn to creating games, Bushnell gave him a project secretly meant to be a warm-up exercise. ... The prototype impressed Bushnell and Dabney so much that they felt it could be a profitable product and decided to test its marketability."[1]

As to why Pong was implemented in hardware rather than software: the first Intel microprocessor, the 4-bit 4004, was released in 1971 and the 8-bit Intel 8008 was released in 1972.[2] Pong was created in 1972, so at the time microprocessor chips would have been expensive and esoteric components with a limited supply. (The 8008 chip cost $120 in 1972, which would be $725 in current dollars.) Meanwhile, minicomputers made of TTL chips were large and cost many thousands of dollars.

>It may be that I fail to understand Apples US reach, but I don't see that owning an iPhone makes customers stay with in the Apple ecosystem. I would be surprised if even 25% of Apples iPhone customers have an existing subscription to an Apple service.

Here’s a short list of some of the things that may keep someone on apple. Most people don’t use most of them. But even having 1-2 may keep someone.

* apple watch

* apple health data

* iCloud photo libraries (sharing with family etc)

* imessage

* certain apps only on ios/mac

* privacy

* apple music

* itunes music library

* now, apple news, apple arcade, apple card

* airdrop

* airpods

* integration between iphone, ipad, apple watch, mac, etc

Apple has about 50% us market share, so a lot of those involve social or family ties. Outside the us these are less important: most people in Europe use whatsapp for example, negating imessage.

But the point is, for each of those bullets, there’s somechunk of people who are deeply invested in it. It csn be a bit hard to imagine on the outside, because most non-apple services are cross platform. But imagine if you couldn’t use gmail, youtube, netflix etc when switching from android to iphone. It would make you think a lot harder about the choice. These aren’t great examples because they’re more important than the apple services, it’s just to illustrate the idea: if you leave the apple ecosystem, there will be things important to you that you can no longer do.

More prosaic android examples would be things such as homescreen customization, better notification management, etc. anyone switching from android has to give those up, and they help prevent switching from android to apple.
> We already have inflation and dark energy but no good reason to expect either of them to be there at all.

I have seen plenty of heuristic arguments for why we should expect inflation to be there, but I'm not really qualified to judge. None of them seem to have convinced enough physicists to be considered standard.

For the cosmological constant, I think it depends on what you consider the "natural" condition to be. The simplest way to derive the Einstein Field Equation is to start from the Einstein-Hilbert Lagrangian and vary it with respect to the metric. The justification for using the Einstein-Hilbert Lagrangian is that it contains the only scalar which contains up to second derivatives of the metric and is quadratic in the metric and its derivative, namely, the Ricci scalar. But that statement is not actually true: there's another obvious scalar that meets this requirement, namely a constant. So the most "natural" version of the Einstein Field Equation contains the cosmological constant: it should be there on theoretical grounds, and that means "dark energy" should be there as well.

Of course that also raises another problem, which is indeed one we don't have a good answer to at present: why is the cosmological constant so small?

> Nobody's going to choose Apple over Netflix or Steam or the like on the theory that Netflix/Steam is "scammy."

No.

In the same way people won't be choosing Netflix over HBO because HBO is scammy.

The whole article doesn't make any sense.

When you buy a computer or a phone, you buy just one and that's it, having more than a computer or phone doesn't make much sense as it's worse than having only one. So Apple needs to make a decidedly (for the costumer) better product.

While in art/entertainment, there's no "better", people consume the content they want, and can have more than one subscription.

You can have Netflix and Apple and HBO and many others, or none at all.

The only thing Apple needs is to produce content good enough that people are willing to spend the mensality.
Reddit users are like a swarm of zombies sometimes. If something negative gets shared about a person or company, you can be fairly certain that there will be hundreds to tens of thousands of Redditors expressing their anger. That anger, whether deserved or not, results in everything from DDOS attacks, phonecalls from thousands of people, people contacting employees at home, death threats, etc etc.

There's also the tale of the Boston Marathon bombing, where some "over-enthusiastic" Reddit users took it upon themselves to solve the crimes based on footage from security cameras. The Reddit Detectives managed to hound and accuse the wrong people: https://www.businessinsider.com/reddit-falsely-accuses-sunil...

So Reddit is very anxious to avoid unleashing the zombie horde again, hence its very strict policies about naming companies or individuals.

Whereas I live in the US, where it is common to have to do a back of the envelope calculation whether to drive or take an ambulance. Pro tip: if you are conscious, you'll never take the ambulance.
Thats a fair point (I don't feel attacked, but thank you). I'm getting more at the idea that maybe we start planning for things to wear out in a more radical way. I was struck by a story about how the Japanese knock down old houses after 30 years (https://www.theguardian.com/cities/2017/nov/16/japan-reusabl...) and while this might be an extreme example, its an interesting perspective. Not without its flaws, but not without its benefits either.
I just want to thank 3b1b, and tell anyone who's trying to get in love with math to go ahead and binge his channel.

I've been terrible at math since they started to get "hard" as a teenager, which then compounded into not liking math before and after getting into college for a CS degree.

The degree inevitably requires some math background at the beginning, so I struggled with that a lot, until I discovered 3b1b.

His series on calculus and linear algebra got me through both subjects in less than a week. From 0 to 7 in the scale of 0 to 10 we use in my university, in just 3-4 days per subject. I regret not discovering it before.

What those two series helped me with was understanding why math is important, and how can one solve everyday problems with math, which is something teachers say when you are young but don't actually tell.

Realising that instantaneously motivated me to put in time and effort, which is key when learning math.

The machine learning series also helped me find the answer to the "why am I learning math if I'm just a tech?" question.

On the side, I'm now reading "Computer Networking: a Top-Down Approach" by Kurose, which made me get to the conclusion that we are teaching things wrong. The educational system that brought me here teaches you on a promise of everything making sense once you understand it all, which makes it really hard to understand the pieces in the first place.

The book takes a different approach in that it shows you the final result, and then breaks it down abstraction by abstraction, which makes you eager to know what's going on behind the next abstraction.

If I were to teach a kid how a mechanical watch works, I wouldn't start by the gears, I'd start by the watch itself, and then break it down piece by piece. Once he knows that there's this abstract system that takes some force in one end, and spits some other force in the other, then the kid will want to know what's behind the abstract system, and he'll be ready to know it.

This way I'll keep the attention of the kid till the end, instead of telling him "you'll understand once we finish" after each lesson.
Yeah, I looked into this a bit. Planes and rockets absolutely require expendable fuel to achieve efficiency; the ratio of wet to dry mass provides an exponential factor to either flight range or delta-V by virtue of lowering weight as it provides thrust. A lighter flying thing can use less thrust to counteract its own weight (indirectly by generating lift in some cases) thus making its remaining fuel more efficient. This is why the Saturn V had an absolutely gargantuan booster stage, followed by a large booster, then a small booster, and finally a tiny Apollo CSM to actually get to the moon and back. Lifting a rocket itself requires an exponentially bigger market just to get you a few km further off the ground.

For planes it’s arguably worse because a plane in level flight thrusts forward and relies on that to indirectly provide lift, whereas weight is always pulling straight down. Also, thrusting forward creates drag backwards.

One aspect you miss in your analogy is that when you include the time dimension, the probability of a collision is proportional to swept volume (and thus speed), rather than static volume. So while the space is really large, really fast objects can have substantially large swept volumes.

Android kernels are forked up to six times [1] which results in kernels that have diverged significantly from mainline. Mainlining a device is no way near as trivial a task as you make it out to be.

In a less capital-intensive industry, you'd see small competitors building higher quality goods for a premium price. You see this in, for instance, leather goods (where you can get very high quality leather wallets for under $100), clothing (much better goods available online for only slightly more than mass-market retail), etc. Small competitors don't care about planned obsolesence when they could only dream about capturing enough market share where planned obsolesence becomes necessary to keep profits growing every year.

But the capital barriers to entry for new cars and smartphones are way too high. Elon and Tesla were the last true upstart to even come close to a semi-affordable premium option, and they burned through billions in startup capital to get there.

If the government can't reduce the barriers to entry for Smith's Invisible Hand to naturally produce competitors, then the government needs to regulate the natural oligopoly.
With these sort of things, it's better to tell the truth and get fired than to lie, and wonder if you're going to get prosecuted somewhere down the line for lying to a federal agent. Jobs aren't so rare; you should think twice before lying.

Edit: Yes, it is better to work at a car wash than to get convicted for lying to federal agents. Don't believe me? Ask any federal prisoner if they'd be willing to work at a car wash in exchange for their freedom.
It should be mentioned that electric motors allow for designs which can drastically lower drag. See NASA X-57 Maxwell for instance. But it will take quite some time for that to translate to commercially made planes.

I think the key to electric flight is just a rough doubling of battery capacity, along with finishing the R&D around new designs like the X-57. Nothing that's out of the reach in the near future.

A doubling of capacity can be achieved with lithium using either solid state electrolytes or silicon anodes. There's a decent chance that something like that will reach mass production in the next 10 years.

This is exactly why I defend him.
My good fellow, I am merely suggesting that if you wish to critique his work, you should study it yourself -- which would be almost impossible now because you will just look for excuses to mold these works to your expectations of them. If you had told me you read his work and rejected it, then this would be a different discussion. We'd have to get into our conflicting interpretations. Right now, however, it just seems like you are dismissing him because the actions and critiques of others. Also, I don't really think this is an issue of "wrong" or "right." A philosophy of life is more in the domain of art than logic or the sciences. Is a painting wrong? Upon what ground do you critique a painting from? How one judges a philosophy of life is more a matter of the aesthetics of the vision than the correctness of it. I know you mean "wrong" in the sense that it disagrees with your view of life, but this obscures the fact that we are talking about aesthetics, not logical conclusions.

What you would need to determine is whether a dimensionless quantity is changing.

https://en.wikipedia.org/wiki/Fine-structure_constant#Is_the...?

If the fine structure constant α is found to change, then would only be able to say that the relationship among the speed of light c, the elementary charge e, and the Planck constant ħ are changing, but IMO if we discovered that (say) α changed from .007300… to its present value of .007297…, we would not be able to then say "the speed of light changed (and the elementary charge and Planck constant remained the same)"

…but as a matter of practicality, scientists could feel free to use a different value for c in the past (and the present value for the elementary charge and Planck constant), if that is the most convenient way to accommodate a change in α. It wouldn't surprise me in the least if holding c and ħ constant is better for astronomers and holding e and ħ constant are better for particle physicists.

(Saying that ħ changes would be similar to saying that mass changes, or at least, the units of ħ include mass, and the Planck constant "is the basis for the definition of the kilogram." in the SI system [well, technically, this is not the case until next month. Right now the kilogram is still defined by the physical "international prototype kilogram" object, but the above quote is from wikipedia])

However, while the best experiments are consistent with changing α, the change in α is constrained to be WAY less than it would need to be to explain cosmological red shift observations.
