For what it's worth, as a fellow immigrant on a work visa (O-1 here… wasn't eligible for H-1B), the stress around a visa status is nothing new. It's been a constant struggle since I moved to the USA in 2009; and all 8 years of Obama were pretty bad too. Trump might be bad, but the immigrant struggles are nothing new, and won't change regardless of whether the administration is blue or red.
He did say that many games are great on their own. But isn't it an inherent feature of console gaming itself, that young people need to invest tons of money to keep up with their peers, taking on the potential risk of the console's failure?
That’s the roulette part. Not everyone wins!
Yeah, poor choice of word on my part, but I feel you. This happens to me a lot with their stuff: the solution is trivial yet not obvious and it's not documented properly so you end losing a lot of time.
it's the thing modern consumerism is best at - optimising for what we want, despite what we tell ourselves about what we want. Oftentimes that results in tapping into reward system hacks like chained clickbait articles or "get X quick" products.
Haha thanks, definitely taking an alliteration heavy approach, just like my inspiration, Ruby on Rails
Getting past the flowery writing style, I can't help but wonder why we Americans are all required to believe that immigration is healthy and important with this evidence that scarcity of jobs for people to do has made life a living hell for millions of people.

I also wonder what educational opportunities the author passed up. I am not a good judge, though. I grew up poor but maybe I was merely lucky to get where I am now. Hard to say. I do remember all the years of crap jobs and few prospects and all the idiots I had to work with--especially the stoners at the country club groundskeeping crew. Thanks for being interesting nutters, though, guys.
They're my needs haha, I sent you an email to become a beta tester
Interesting! What makes a programming environment "Smalltalk-like" and what are some examples?
PoW comes with huge energy and computation requirements that can make scaling infeasibly difficult. It's possible, but challenging, to design a PoS system that is secure and does not consolidate power in the hands of those that own the most currency. This document[0] has a good description of the arguments for PoS and an overview of the theory behind it.

Biggest thing seems to be writing non-trivial GraphQL + Rails backend. It was quite interesting work: there is still not really much best practices for this combination, so just to make it work in a Rails way did take some time and trial and error. At the end I am happy with results and I hope to find some time to publish blog post on it.

Other than that: I did some face lift for my side project http://notationtraining.com and implemented new MIDI API to connect midi (piano) keyboard directly to web app.
First, the obvious lesson: everyone install an ad blocker.

Secondly, my own anecdote: at work I cannot install an ad blocker, nor manage other aspects of being tracked online.

As part of that employment, I recently had to do some research on equity-release products/reverse mortgages. These are products targeted at the elderly.

I am not elderly, despite what my 20 year old sister in-law might say :p

My workplace online advertising experience has now become an endless omnipresent stream of older couples looking wistfully out into the sunset, perhaps on a boat or over an ocean, or smiling lovingly into each others faces in that aspirational retirement way, always with the message: sell us the equity in your home so your life can be like this.

And it's not just instagram. It's following me everywhere.

Anecdote 2:my mother before she died, was basically a paranoid schizophrenic. Imagine, for a second, the subjective experience the internet advertising system has on these people and their families.

I had an eye opening conversation with her a few years ago, where she proclaimed that "they" were watching her through the computer, and she knew because of the coincidences in how the content changed across the internet to target her specifically.

I had the failed experience of trying to explain what was going on, and the observation that, dismally, she was essentially, on some level, right. The ability to make a mentally ill person's ramblings essentially correct is a sobering dystopian realization...
Is MS Hotmail the email service that modified every outgoing mail to have an advertisement for itself in each email? Kind of like a vastly more aggressive and earlier version of 'Sent from my iPhone'? I can't remember if it was Hotmail or Yahoo or both. But all the other advantages of Gmail aside, not modifying your outgoing mail to include advertisements is a big one.

There is a way to opt out of it:

a) leave instagram

or

b) stop being butthurt and envious of other people's appearance

Your choice.
Did you take a look to java.lang.invoke.StringConcatFactory, it does more or less what you want using method handles instead of bytecode generation ?

Because most people on HN and the moderators support censorship. Especially on social media and the internet. So far they've been successful in taking down silly accounts like milo and some "right wingers". But their ultimate goal is to get censorship controls like iran. It doesn't serve their interest to criticize iran for doing what they want to do themselves.

You have to keep in mind hacker news is a misnomer. This site hasn't been run by tech. The mods are former unemployed media employees. They know nothing about technology. And most of the people here are left leaning anti-free speech types.

There is no hacker ethos to hacker news. It died many years ago.
Indian government is really corrupt and don't have any self respect. India should ban all American companies in Indian soil pushing Indians entrepreneurs down. Companies like Coke, Pepsi, KFC, McDonnell, Starbucks, Google, Microsoft, Amazon etc and away lot more should be banned to operate in India and Indian entrepreneurship should be promoted. if India does that, I ll any day go back to India as a proud Indian. Since India is corrupt and has no unity to stand up against American imperialism, I have to fight here to go up. This is ridiculous. As top 15% of this country benefit from me, I have to take stones from bottom 5% percent of losers who does't blame them for their position and hit on colored people to feel good about themselves.
Or... point-by-point:

So it knows which store I'm in. See also: scanning my member card before checking out.

> Camera:

So it can scan barcodes.

> Wi-Fi connection information:

> view Wi-Fi connections

...but not control which ones to which you're connected. How often does your list of Wi-Fi connections matter when you're at the store?

>Other:

> receive data from Internet

Download item info?

> view network connections

Make sure it can get to the internet.

These all seem reasonable for a self-scanning app. But then, a paranoid person could find reasons to be afraid of water: https://en.wikipedia.org/wiki/Dihydrogen_monoxide_hoax
I was with you up until "possible, but challenging". How...
It is a much weaker requirement than PoW. Part of the reason PoS (a fitting acronym) is successful is because people are hysterical about Bitcoin's energy usage over time.

Rightly so. Bitcoin uses a lot of energy, and it's fair to worry.

But throughout history, people have always capitalized on fears to get something. Careful that you read these proposals with a skeptical eye.

There was an excellent comment on HN that unfortunately I can't dig up anymore, but it went into detail about why PoS has all kinds of subtle issues. Basic issues, like who gets what, can end up with weak guarantees.

It's important to remember that Bitcoin, for all its flaws, is almost unkillable. The sole way a government can kill it -- any government -- is to invest >$2B into getting >51% hash power, then launching coordinated malicious doublespends for the purpose of shattering faith in bitcoin.

That's it. There's no other way.

PoS weakens those guarantees, and before this gets pushed through, it's good to understand in detail what the tradeoffs are, and game out whether that could give centralization any advantages.

(And if they say there are no tradeoffs and PoS confers no advantage to centralization compared to PoW, maybe research it and decide for yourself.)

This whole auto-drop-my-comments-to-the-bottom censorship is really tiring and just a way to discourage certain people from contributing to HN. I've been a member here since day 2 of the launch of Startup News, and this feels quite unfair. My pleas for reversing this decision have gone unanswered, so I have no idea what to do about it other than rant periodically until I get banned. Nothing good will come of that, but it's just a completely bogus situation. (Yeah, moderation is hard, and I respect that, but jeez. My comments all start out at the bottom and stay there.) </rant>
Because we live in a police state and even escaping custody is only step #1 in escaping. How many people escape for good? Next to none, I would guess. It requires getting away from the immediate area and getting to a new location where you can develop a new identity somehow and you're always on the run because of finger prints and biometrics. I would say there is no place to run in the US, even in the remotest areas, there's no way to get work no questions asked. You would have to escape to Latin America and join a drug gang or something and hope you don't get murdered.
I can't wait for this to be fleshed out and implemented on Mainnet. I'm working on a smart contract that I want to integrate with Casper's API.

I'm thinking of an analogy, maybe it isn't a good one, but it's if you're trying to quit smoking, and somebody is deliberately applying stresses to you, that are known to be associated with the desire to smoke.

I don't think it's OK for anybody -- corporation or otherwise -- to saturate me with messages that are tailored to my psychological characteristics that are only partially under my own control.
I was in highschool when a girl commented to me, "You are going bald." The next couple of years were rough, but eventually, I just owned it. Sure, I'd probably rather have hair than not, but it is what it is. Now in my very early 40s, my beard is more grey than not. Apparently hair doesn't like me. Now I see people with hair all the time in commercials, and in real life. Doesn't bother me. But if I were targeted over and over by ads trying to make me feel bad about being bald, and just go get hair plants already, well...I would not like that at all.
The estimates are real and from Dominos. Thanks for the feedback, that's a good catch. I'll be adding that verbiage.
One important point is tat Proof-Of-Work is based on destroying value (electricity) in order to prevent centralization of control.

If (!) Proof-Of-Stake is able to achieve the same thing without the costs associated with PoW, then it is simply more efficient.

This means that the same value (secured cryptocurrenty) can be obtained at a much lower cost.

From a macroeconomic perspective, it is clear that equal results at lower cost must benefit the participants of the economy.
It isn't a core tenant of PoW that the resources needed to participate are hard to get, it just so happens that if it is profitable to 'mine', the hardware needed will become scarce. That actually creates a problem, much like in the Bitcoin PoW algorithm, that its easy for the hardware production and ownership to become centralized.

PoW also requires large energy consumption as participants will inevitably enter a race to compute the fastest.

PoS has the benefit that you still lock away capital, much like in PoW, but rather than backing that capital by money put into hardware and electricity, you cut out the middle man and base the capital off of the value of the network token.

Pos also has added security benefits. Vitalik Buterin explains this very well: If someone attacks a PoW blockchain by getting 51+% of the hashing power, the network's only response to recover from the attack is to change the hashing algorithm. This will likely force the network to abandon ASICs since hardware wouldn't exist, and move (at least temporarily) to general-purpose CPUs/GPUs. As soon as the hashing can be done with general purpose computers, the game is over, and the attacker can attack forever without any extra loss of capital, other than electricity.

PoS has the benefit that the network can simply cause the attacker to lose their funds and no longer have a stake. If the attacker wants to continue the attack, they have to buy more of the network token to be equal to 51% of the staked value. This will cause a price increase. Each time the attacker attacks, the network will force them to lose their stake, and their money. The attacker won't be able to keep this going forever.
Was just reading about the 3DO because I was gonna write an emulator. Wikipedia and others point to steep price tag, the spec-only-third-party hardware approach, and that they didn't collect many royalties from the games as the reasons for the downfall of the 3DO. But as I looked around and read, it seemed they were super proud and stingy with the tech (expensive devkits iirc), and the tech was about 2 years too early and just a bit before the 3D revolution that came with 5th gen consoles.
Surprising, isn‘t it?

Then again, maybe we should use data to inform our opinions (inform, not determine), rather using our opinions to filter out data?
I'm sorry, this is nonsense. There have been lots of periods of industrialization and they didn't all result in mass starvation and penury. In fact, many of them _reduced_ poverty by freeing people to focus on new fields in which they had a better comparative advantage than they had at ditch-digging and partially reducing the economic incentive for enslaving others.

Doesn’t really matter. With modern CSPRNGs, even if one input is compromised you’re still as strong as the remaining entropy (as long as those sources are statistically independent from the compromised one).

If this was the only source of randomness it might be a problem, but if they’re `cat`ting it into `/dev/random` as an external source, it can only really improve things. Even if someone were to compromise the feed from the office to the datacenter, it wouldn’t matter since they’d have to know the internal RNG state in order to “negate” its randomness with the lava lamp feed. If they have that, you’re already lost anyway.
Text algorithms (swipe, prediction and autocorrection) create issues on performances of the mobile devices (swiftkey for instance is super slow) and often mistakes due to misunderstanding meaning slowing down the typing experience.
Our Responsibilities
I believe you're referring to this comment: https://news.ycombinator.com/item?id=16042243

It mentions other related equipment also being destroyed, which also strongly hints that this isn't just plain vandalism.
How is it possible or how is it challenging? The FAQ document describes both. It relies on a principle called "Weak Subjectivity" that Vitalik describes in detail here: https://blog.ethereum.org/2014/11/25/proof-stake-learned-lov...

I'll admit, that I don't have a complete understanding of the theory behind PoS systems, and there are certainly tradeoffs between PoW and PoS, but Vitalik makes the arguments that the benefits of lower energy consumption and quicker transaction fees outweigh the weakened guarantees. Whether you agree with him depends on your values with respect to Cryptocurrency.
The author is misdirected. This isn't really an Instagram problem. Instagram didn't make the ads. The advertisers did. If the ad is successful, it continues. If it is unsuccessful, it is removed. Clearly, these are the successful ads. The fact that author is triggered by them seems to indicate the problem is with the author, not the ads.

The vast majority of users have no problems with the ads, or the ads would change. The vast majority don't write 5 pages of medium.com screed about the ads. The vast majority are imagining themselves as the woman in the ad and buying the products. That is simply how the algorithm works.

The nice thing about the internet is everyone can have their say. The less nice thing about the internet is that includes everyone, including people with serious mental issues. Articles like this one, or infowars, or any other sort of militant fringe generally attracts more of the same sort of voices. It makes the fringe seem legitimate, because there's a balance of for and against in the discussion.

The vast majority disagrees with the author. That's how the algorithm works.
I guess so... but headline-grabbing news around immigration does seem to pop up more. And then I have to dive into that and figure out if this applies to us or not.

Definitely leaving a bad taste. Some amount of "lock-in" period to laws so that people can plan their lives better would definitely help. But hey... I'm no lawmaker.
The ROI on that seems pretty bleak from a business perspective. Without paying customers’ usage to bankroll the buildout, I find it highly doubtful that any carrier would agree to emergency-use only stations.
Environment Is Not Culture
Also, if you think that Keynes advocated a negative interest rate, you should read Ch 16 and 17 of the General Theory.
Clever scrolling taglines. Seems like your target audience would be a party crowd, and you might want to play that up a bit.
That is a fun effect. And the generation of microwave RF energy (experienced as radio interference on Cell phones in the article) suggests you could rectify some of that and extract electricity directly from the effect. Depending on wear on the crystal plate of course. Assuming the crystal does not erode significantly over time, then you build a rectifying antenna around the spot where the torus will form, these are small so you have hundreds of thousands, perhaps millions, of these stations under the bottom of pipe which is fed by your local reservoir. Water flows in, power flows out, no moving parts. That would be pretty neat.
For those who are interested to know how much App Engine Standard Environment roughly will cost in real world applications here is my simple formula for it:

Average RPS * $15

So for 100 RPS for one month it costs around $1,500.

Also, you can optimize for cost by adding the following to your app.yaml:

threadsafe: true

Also Golang and Node costs less than other environments.

My two cents.

"That you and vertex-four disagree not only on the facts, but on the nature of facts indicates that perhaps his point has some merit."

Unlikely. One of us has spent a large chunk of their professional career working in and around newsrooms.
Spent the first half at a startup I'd been working at for about a year before getting acquired by Amazon and joining the Alexa org. Made peanuts on my options and left after a few months to start a cannabis company. Our aim is to manufacture and distribute high quality vape cartridges and pre rolls while contributing to the liberation and well-being of the drug war's many victims and their communities. So far, so good! :)
I don't know what the US market is like, but in the UK it's easy to find glasses online with Zeiss, Nikon, Essilor or Hoya lenses. For what it's worth, I need six diopters of cylinder and have had no problems with unbranded CR39 lenses.

Bitcoin Cash has 8MB blocks today, 8x larger than Core.

Core propaganda will decry this as lunacy since people won't be able to run nodes on raspberry pi's anymore. The sad reality is you can buy the hardware required for the cost of a single BTC transaction.

BCH nodes/miners can increase to 32MB without a hard fork, it's just as a config setting.

GB blocks are possible today with today's hardware, though those won't be necessary for quite some time.

TB blocks are almost possible today, though a little further out in practice.

The vision (and current reality of BCH) is that every transaction should make it in to the next block for less than a penny.

Low/non-existent fees is the only way a meaningful global exchange system will emerge. Better to have everybody on the globe doing 5 transactions a day for dust than to have a few hodlers transact twice a year.

What interest drives HN? HN is no different than FB. Except instead of "high profile" accounts, you get a mod selected drivel.

Ultimately what you are saying is that you want stuff you agree with. That's it. That kind of thinking is why we got the facebook we currently have.
There’s no such thing as a free lunch. If Insta offered an ad free option for $10/month I wonder if the author would pay for it.

A race to zero is what I’m after. It’s been/being done in other places, it can happen there.
Did you speak to a lawyer? Firing you for that sounds illegal.
You've misunderstood my comment. I'm not arguing against the idea that Bitcoin is a poor medium of exchange, I'm arguing against the idea that the sort of actions taken by the Fed would help. Rather, the Fed acts on a much longer timescale which are relevant for store-of-value roles.
A strict definition sees many governments tarred with this brush, with the US, Russia, UK being stand outs. Others see the terrorists as freedom fighting, and they have some good points. This line of arguing achieves nothing, but that’s the point isn’t it?
