My advice: Do. As in make shit. Pick something you think should exist then figure out how to make it. Pick a reasonable goal; ie don't attempt to build a self driving car, at least not straight way :).

I follow what i call Just in Time Learning, I learn what I need to get the job done. I started with graphic design transitioned to web and application development, and currently an cloud infrastructure engineer. Leverage expertise you develop in one field to move to an adjoining field. Currently playing with cryptocurrencies and ML.

Leaning for the sake of learning is boring and imo; at least for me, not very effective.
The multiple device part seems tricky to improve on. I don't see how this approach can be tweaked to make it easy for non-technical people to access on multiple devices.

It seems like you have to define a new device on a existing logged in device before using the new device. Is there a way around that? If I want to log into an app for the first time at work and forgot to define a new device name at home where I already can log in, I wouldn't be able to do so from what I understand.
I saw a tv show comparing UK and German family, life from BBC. I don't know how accurate or biased that production was but from an outsider, I marveled at the amount of infrastructure built around supporting traditional Germany families. For instance, women who marry are incentivized to stay at home and take care of the children and home. Similarly, kindergartens spend time outside away from books and a long career of state sponsored rote memorizers. Even more fascinating is they don't seem to force school on people who aren't interested in it, instead providing stable and secure trade jobs which you will master in some apprenticeship...backed by monopolies built from the ashes of WW2, dominating global markets....trickledown effect that actually works.

of course....my view will never fully reflect the realities of an average German living in Germany....I'm basing it off on that BBC show anyhow so I expect to be wrong in many areas....

but I still admire the German system as described, not sure how well it's implemented....

So you are evaluating the quality of a 28 pages paper by reading only the introduction ?

Are you intentionally retarded ?
There is no content.

From the intro, I was expecting some kind of analysis of the most promising "next-gen" crypto currencies, and how they are better or not better than Bitcoin. When I got to the end I thought for sure there was more to go and maybe the page hadn't loaded fully.

That seems like a rational reading.

"that is reasonable in the circumstances" may be ambiguous and in the eye of the beholder. But it certainly suggests that a normal 16 year old doesn't need to be automatically under constant adult supervision at all times.

ADDED: This may or may not be the correct reading, but I take that as saying you can't kick your 15 year old out of the house and tell them you're on your own.
> I'm not sure how much clearer you could mark that.

It's not about this warning. It's about that it's the only warning. From the intro and from discussion here on HN, I imply author knows about other shortcuts made for the sake of simplicity/explanation/readability - I just wished those shortcuts were pointed at more directly in the article, instead of blanket disclaimer.
I walked from home to elementary school daily ~3 miles in Queens growing up in the late 80’s. I was almost robbed once, but I was luckily able to avoid harm. Otherwise it was a totally uneventful experience. My nephew did get hit and injured (minor) by a car in Manhattan on the way to school (hit and run driver), so I guess that risk is real.
Nonetheless, this dopamine meme is getting quite tiresome.

Oh no! U hacked my dopamine!

Let’s come to terms with the fact that self control and executive function is more than capable of overriding the urge to play video games.

A bunch of VC drones throughout silicon valley are backslapping over how brilliant their neuroscience exploit payload was, because it makes their status seem so much cooler, and it’s abstract enough that it defers real responsibility.

It’s the tech version of the agribusiness meme of victimization by genetic propensity for obesity.

But maybe transfats and refined sugar have more to do with obesity than genes.

And so, if we really thought carefully about social media and smart phones, rather than capitualting to the macguffin of dopamine, which has very little actionable meaning (in the same way the story of genetic propensity leaves the individual with little room act against a fatalistic assessment) maybe it’d be a better choice to look at real motivations, than to defer to unassailable buzzwords.

Do you have a link to the source? I'd love to check it out.
Thanks, I'll give it a look. Last time I looked at the subreddit, there were various people working on Ubuntu respins, but none of the projects looked like a frontrunner yet for a low-maintenance build.
Mathematically, it's a question regarding the order of limits. Evaluating 0^0, is akin to considering a^b as a-->0 and b-->0, and the order in which the two limits are taken will make a difference. If 'a' approaches zero and while 'b' is still positive, the answer shall be 0. If 'b' approaches zero while 'a' is still positive, the answer shall be 1.

Pragmatically, what this means is that 0^0 is not sufficiently specified (just meaningless symbols) unless you prescribe the context/meaning with which you're using it. And with regards to defining summary statistics, the article talks about a context where the exponent scans over different (continuous) values, passing by {2,1,0} along the way.

It should be an interesting exercise to consider what happens when the exponent approaches positive or negative infinity i.e. large magnitude positive or negative numbers.
This made me so unbelievably sad. A country that was prosperous, educated, full of natural resources, gets destroyed by a corrupt and despicable political system. There is no reason this should happen.
Yes! Lots of them actually.

1. The gaussian distribution is important (all sums converge to it) and the squared difference from the mean characterizes it.

2. Euclidean space is important, and squared errors stay the same if you rotate everything. (Other errors don't).

3. Linear regression with squared error has a closed form solution. Other types of models converge very fast when using it because the further you are from optimal, the bigger your gradient is.
Oh, yes, the so called management. You report a damage by a protected creature (tractor crashes through ground into dug out beaver lodge- breaking axle)- some state official hippy appears, looks at the damage, gives you 100 € promising to bring a trap and evict the beavers (nothing happens), promises further compensation (nothing happens) - disappears, talks to the newspaper that he cant understand the outrage against geo-engineering animals in the neighbourhood of farms and living centers. After all they recived compensation.

I know farmers who do not allow those lying hypocrites on theire grounds.

They said that the pair I got and returned was defective and "want to make things right" by sending me another, free pair.
I like this idea too, along with also adding a network so that the cars could all communicate to each other. I have always found horns and turn-signals to be lacking in the amount that can be communicated to other drivers.

The problem with an inter-city highway is that you would have to require every car driving on it to be able to recognize and interact with those sensors. That would be decidedly unfair to those who cannot afford to upgrade their car to go on that road.

So that does bring up an interesting question though, when and where are we going to have roads where only autonomous vehicles are allowed?
The thing is Volvo's experiments haven't been going as well as others.

In the race to build a functional autonomous vehicle some companies are getting it done, and others, in spite of big promises, several years of effort, and scaled, well capitalized operations have very little to show for their efforts.

Everybody still has a lot of work to do, but the operations that can, at the very least, demonstrate as proof of concept their cars handling just a few miles of of uninterrupted driving in dynamic environments have cleared the biggest hurdle. Following that big hurdle is the validation process, which is tens of thousands of smaller hurdles stretching out as far as the eye can see, but so long as they've cleared the first, biggest hurdles, you can be reasonably confident they'll get to a minimum viable product eventually so long as they keep at it.

I have confidence in Waymo, GM, and Zoox. With everyone else it's either too soon to tell, or I don't have enough information, or they're sucking:

When I was a child, probably between the ages of 6 to 8, I liked to make model gliders from balsa wood. My father taught me how to cut the balsa wings and fuselage from a plywood template. Once he's seen me do it a couple of times, away I went with the Stanley knife (not sure what else they're called in other parts of the world. Retractable utility knife perhaps) and was making my own gliders. Not sure why, but this day I happened to be kneeling, rather than working at the bench. Sure enough, the knife slipped and embedded itself in my thigh. Three stitches later, I had learned to be really careful with sharp knives and how to cut things more safely.

I've driven a chisel into my finger while trying to finish a mortise and tenon joint. Use a vice, not your hand, to hold the wood. Came close to ripping out an artery while climbing an aluminium fence, just ended up with a nasty scar on the side of my wrist. I took much more care climbing fences after that. Barbed wire fence scars across my legs though. Can't even remember how that happened.

Anyway, kids do stuff and hopefully they learn without killing themselves. A few cuts, scratches, a bit of blood and some stitches seems like par for the course.
The Russians had a ‘thing’ for balanced ternary computers during the Cold War (parallel technological universes et cetera), and the last one developed in the west is reported as dating to 1973.

Thanks for the generous reply,

I'll admit my professional work has been limited to C++, python, Ruby, PL/SQL, Matlab and small DSLs. I've played lisp and the-fp-languages in college. Lisp and the-fp-language both seemed to at least have clean, simple syntax rules.

I started using Ruby both it was hip and because it's free form syntax was really fun. If there were languages I definitely to learn, I would be less critical about syntax and style.

My original comment on Clean's syntax wasn't intended as a full judgment on the language but simply a reaction, a reaction I shared because it seems like subjective impressions of syntax matter for the reasons I mention above.
Part of what net neutrality ensures is that Big Tech can push as much data across the internet as it wants; Big Telco has to deliver it.

Ugh. Net neutrality supporters have not done a good job of explaining why this is not the case. Netflix already pays for all its traffic, and ISPs are perfectly free to charge subscribers more for higher bandwidth or total transfers.
Did I miss the point of this?

Of course not. No one cares about Yemen because atrocities are being carried out by a US ally. It's plain to see when and where the media generates outrage.
Pro-rate everything.

Then there's no incentive to cut apart a single real job in to multiple small ones 'to save money'. (Though there may be reason to take a partial job EG during school hours for parents.)
When I started teaching myself I never thought it would take me so long. I made two mistakes: I didn't have direction (which you solved by asking a question) and I didn't build stuff.

From this point forward you ought to pick one thing and build stuff. When I say pick one thing, I mean one learning resource at a time. Whether it is "automate the boring stuff" (which is a great resource I haven't read) or one of the resources that I'm linking to (they are different resources that have been suggested on HN in the past), or a suggestion from another comment. Pick one and work on it. It's all about making a decision and sticking to it until you have enough information to make a better decision.

Find someone you can talk with about this stuff. It can get lonely if you don't know anyone who knows about this stuff. I'm available and would even work on some of the material or courses with you, especially the last two links.

As another user mentioned somewhere below, you will feel like bashing your head against the wall. He/she wasn't kidding. Once you get past that feeling, which will take a very, very long time, you will have overcome the hardest hurdle.

Raymond Hettinger, Keynote on Concurrency (PyBay 2017)
I used to think that economic collapse after the fall of Soviet communism was the worst outcome possible. Now it is apparent that crash with communism intact is much worse.
I built something similar a while back to test card game ideas. Hopefully someone extends this to add other game objects and mobile support.
It was government corruption, not socialism that led to the current crisis.

Socialistic Scandinavia countries that have sovereign wealth funds from their oil extraction prosper.
I don't. The only reason I heard about it was because I happened to be playing when the dev hopped on and started messing with people. Someone asked him about architecture and they said they use two websockets to prevent congestion.

I'm skeptical about the design, but the only way to know whether it's effective is to measure it.

Carmack's great breakthroughs came from trying every logical possibility and then sticking with the ones that worked. There were dozens of dead Quake designs that no one knows about, e.g. beam trees.

One mistake I made in the early days was to go around asking people what to do or how to design something. The truth is, no one really knows the best way to design anything. The only thing you can do is think of possibilities, try them, and ruthlessly measure whether they're effective. Often the most effective designs come from unexpected combinations, which is why this dual websocket idea is worth taking seriously.

One nice property is that if it does work, it only costs 2x bandwidth. Realtime games' bandwidth grows as O(n^2) with the number of players (e.g. 90 players need updates about all 89 other players plus themselves). So doubling the bandwidth isn't a huge cost.
Wow that multiple TCP connection trick is very interesting. Each additional idle connection would theoretically be capable of firing off a single packet instantly with no congestion control getting in the way. I'm getting flashbacks of services that would allow multiple pending HTTP long-polling requests at once, so the server could push faster than the round trip time.

I wonder what the ideal number of connections would be. It could certainly be 2 of course; I've never thought about this problem before.
In Poland, drugs were way too expensive to be widespread up until the fall of communism. After that, people were generally more aware of how bad drugs are (AIDS, the overdoses of rockstars etc.), so I’m guessing they were reluctant to even try them out and the drug culture never caught on.
I don't know. Maybe. What's your argument that we shouldn't?

I'm not ready to argue that this is the best possible way to go about things. I just don't agree that it implies that those doing the hiring necessarily think segregation is more effective for teaching.
To expand on the other answers, if you want a notion of angle between things then you need the distance to be defined by an inner product (dot product). This leads to the square. So, in some sense squared error generalized our geometric intuitions the best.
SALE Palette – color manager for iPhone almost free
Almost certainly. One of the wider goals of past projects was to influence opinion over large groups of people. It seems likely that the various state forces using social media to sway opinion come from research on influencing opinion.

Additionally, the US torture of alleged terrorist detainees was called "enhanced interrogation" as a link to such testing. As we still have black sites, and a desire for more information, I personally assume there is still testing being done.
Socialism ends this way every. Single. Time. “If only socialism was implemented correctly for a change!” The snowflakes chant. Ignoring history. Implementing more and more socialist programs at home. Sigh.

That is the automatic price suggestion of SEDO, the real price could be different. Important to know that it is a one word name and the gTLD extension was introduced in 2014, the date when I registered. It was supposed to be my personal project and that is why I paid a premium price during Early Auction. The idea is not dead after almost 4 years but I'm slow at programming doing another project. There are a few sites who are smaller than SEDO and who try to make a profit by helping people to sell domains and I want to find them.
> The popular idea is that it has something to do with, you know, freedom and democracy and all that.

In practice, it has more to do with anti-trust. But it's clearly related to Internet freedom as well.

> Big Telco must share the costs of carrying all this new traffic.

No, it's about double dipping. ISPs are already charging their own users for using the network. What they want to do, is to also charge services for reaching the user (or at least not to have problems with interconnection). It's a pure troll tax of the type "because we own the bridge". There is no justification for that.

> Today, picking a side in this debate seems like throwing in with one set of corporate assholes over another.

> But if we entrust Big Tech and Big Telco to preserve those virtues, then we definitely deserve whatever internet we get.

The author contradicts himself. If he doesn't pick the position about Net neutrality, monopolists will do it for him.
It's a well known event in the lead-up to the original US invasion of Iraq. If you don't get why it's relevant then no point having a discussion.
That’s not quite accurate. They also have the US paying largely for their defense needs. That saves them a ton of money.
The capitalist has enough to do just taking care of his own business. But now he has to deal with all these who just took government money for nothing and can compete without any costs on their side. Even offer same service for free because govt pays for it - what kind of business could beat that?
And what kind of government strangles legit businesses and replaces them with state-funded zombies?

I read the paper yesterday (except some parts of section 4). Some of the math was too much to understand for a quick read. It is a good paper. I could follow everything (despite late hour). My problem was that the paper only discusses tangle-technology and finishing it I still wondered how IOTA uses the tangle and how it works. Maybe I should read more about cryptocurrencies first. Or there should be a more general paper about IOTA.
As Yemen Collapses, NYT Publishes Saudi Arabia Propaganda
Anyone knows why so many non-google product project (with a big disclaimer that this is not google) are hosted on google's github?
This is excellent. That's the approach we have taken with the Qbix Platform, taking care of all the syncing and realtime updates and offline notifications and user accounts so you can just throw some tools on a page, make a new type of stream or tool (such as Chess/game) and it just works across all devices.

There is a lot that goes into this - for instance offline notifications must be delivered to each user's preferred endpoints (in app notifications if they installed cordova app, sms and email fallbacks if they didn't), you need to fill templates, enforce access control (can I see a guy's last name or a particular game / chat / etc?)

If you look at https://qbix.com/platform/features you will see we went with Streams and Messages rather than syncing data structures. This allows us to reason about explicit "moves in a game" or other changes and whether they are authorized or not per Stream.

In short - I am happy to see others adopting similar goals. Most of what I have seen til now has been syncing static data structures.
