Ask HN: Can Cryptocurrency Beat Credit Card in Consumer Micro Payment Market?
Amid all the hype on cryptocurrency, I think in consumer (espcially in micro payment), credit card is better than cryptocurrency because:

1) it has cash back;
2) it has no fee in most cases (still some website/service will charge you though, but even for cryptocurrency if you buy on coinbase, say, you still have to pay some fee), but nowadays it is very hard to let the payment to go through without adding some transaction fee;
3) the payment is instant for the user, meanwhile bitcoin is much slower. Many altcoins are fast but still the credit card payment is just fast.

I am not saying cryptocurrency cannot be backing the credit card company to do the transactions transparent to users. That is possible. Because for that use case, all my argument above for credit card can still hold for cryptocurrency.

I wonder what you guys think if consumer using cryptocurrency directly for micro payments can be a reality, and why?
UK police are nowhere near close to US police in terms of everyday brutality. Generally people in the UK are comfortable with the police.

There's a few big exceptions: policing in Northern Ireland was so sectarian it had to be rebuilt. The Met (London) police have a bit of a race relations problem, although again nowhere near as bad as most large US cities.

And the police have a record of tracking and interfering with peaceful left-wing political groups to a disproportionate extent. There's cases outstanding relating to undercover officers who had relationships with women they were spying on.
Would you like examples of what makes Kotlin more unique or different then Groovy? Just at a glance it appears scoping is handly differently then groovy. Also the official language says it supports compiling to JavaScript on the website while its another project for Groovy. Gooscript hasn't been available since 2012. I wouldn't be surprised if Google hopes or plans for people to adopt this for both web and Android development.
Most? Do you really think so?

In my experience, the vast majority of everybody is still bumbling ahead with post-it notes and simple, memorised passwords shared all across the board.

Obviously you can't explain it to a whale. What are you even talking about? This is a message board for human beings. The topic was what choice the animal might make if it had the reasoning skills of a human being (and all the facts).

>How does this make the practice any less cruel?

It doesn't. It's arguing that there might be at least some long term potential benefit to the practice for the species and therefore morally defensible (if the alternative is letting the animal die slowly and painfully).

I don't pretend to know all the answers. But lets at least be clear on what the question is.
Wouldn't bacterial growth be a concern in a wet, warm environment for an extended period? Even if the food was bacteria-free, the container can pick things up from the environment. Even if it's low-risk, on a long thru hike I wouldn't want any risk of stomach issues.
There's also plenty of blaming of teacher's unions for shutting down "innovative" approaches

So the interior heartlands needs to be treated like developing nations and oppurtunities should be opened to them and environment created such that industries move in there. If Chinese people are ready to work for pittance and if the heartland is truly in depression for 20 years then industries should be able to take advantage of low labor cost from the heartland just like they could from China and thus accelerate the growth of heartland communities.

But isolationist policies are not the answer otherwise you are going down the wrong path.
I'd encourage you to view the show through a less ideological lens. One of the compelling aspects of the show for me is that the characters are written as human, rather than some tropes. While you may not always agree with the actions they take, you can understand their motivations. And for the most part, they're not simple, by-the-book, characters.

The Season 2 example you provide I think is a good example of this: McNulty is a flawed human (just as we—and all the characters on the Wire—are) and is fully capable of wanting to do right and sometimes not behaving perfectly, just as the people at the station. I think these reactions were quite realistic. Would McNulty have stopped the prostitutes? Would people hearing of the station had other reactions? I'm interested to know how you would have had it play out differently.

Good art can allow us to reflect on the state of our humanity, just as you have here. Some art can be inspirational, but not all of it needs to be. I think the Wire does an exceptional job of illustrating how difficult it can be to fix real problems in some American cities.

So what's your proposal to deal with people arriving under false pretences? Also you say refugee but let's admit a lot is simply economic migrants. Reminds me of the woman in Guatemala that tried to get refugees status due to being a woman in Guatemala. Ya, it sucks, but you're no more at risk than the other 100M people in the area.
I get giddy thinking about The Wire. It's awesome to say the least. Gave me a new perspective of America.
Talking about the great firewall, didn't Bono of all people praise it as a demonstration that filtering the net was possible? His statement was in the context of unlicensed copying (aka piracy).

And frankly if they want to deal with the rise of nationalism, they need to have a long hard look at the financial market and their destructive behavior.

What is needed is for the big finance houses to fall, and for the Euro zone to drop the whole austerity insanity.

Until then the left have no proper counterpoint to the rising nationalism, as said nationalism is largely feeding off anti-austerity, and thus anti-EU, opinions.
If global internet was a reality I could see working remotely on an airship as being quite attractive as well, just go wherever slowly in your flying apartment, stopping to pick up food & supplies once a week or so, and occasionally mooring in places you enjoy for more extended stays...
That sounds like the smartest play. I suppose I just want to build something and this seemed pretty cool and possibly useful. I'll invest more time in Jira and try to follow its philosophy. If it's still not working for me in a few months time I'll see what tweaks can be made. Thanks.
Exactly. They are not comparing apples to apples.

Firebase API has gotten slower over the years. That affects Interactive time and lighthouse score. Preact HN uses their own servers, and React HN uses the Firebase API.

Also, some passes site is progressively enhanced check because some elements are rendered without JS. Which results in higher score.

Preact HN loads offline but without content. Lighthouse assumes that app works offline, but in reality app is useless without actual stories.

I use Firebase API in my web app (https://hn.premii.com/) and scrap YC in my downloadable app (https://hn.premii.com/about/). Both has different actual and perceived performance.

Write operations are not possible with HN clones as there are no YC apis. They should build reddit clone. I have build reddit clone https://reddit.premii.com/ using their official APIs.
> when climate change causes their crops to stop producing, they can't make money, and can't eat. Africa has been pretty hard hit by the changes in the climate caused by green house gas emissions.

Do you have anything to support this? I am not a global warming/climate change denier, but from what I have read, much of the farming problems is due to population growth and increased strain on existing irrigation sources. I have a hard time making a connection between a bad crop and political instability.
Not everyone can hire the best.

Everywhere I've worked in the last 15 years has aimed to hire the best, none have succeeded.

A "hiring the best" motivation can easily become anti-diverse, because it plays on people's biases about what constitutes "the best", it can also foster a culture of arrogance

Do we ever think about hiring good enough for the tasks at hand?

Why not? It might help them save some of their funds for retirement. But what could be even more valuable to an Ethiopian farmer is access to a futures market. Then he could hedge the price risk for his crops.
Says you. :) I've seen versions that would do just fine with the separated part mixed in. (They're not just with Granola.)

At least we can agree that if there is an Ikea effect, then it is present in mixing your own Yogurt.

However I am not convinced about the presence of the Ikea effect, as there are many classes of product it could apply to but, I don't see such product packaging. don't.

If you go into an electronics store (a demographic that you would think responds stronger than average to the Ikea effect) most items are absolutely fully assembled. There is nothing to snap on, pull off, a sticker to apply, a thumb screw to screw in or unscrew, nothing.

So if the Ikea effect is real (across a variety of product types), I am sure someone has done a test like to see it demonstrated by someone doing a blind AB test using two shipped versions and comparing customer satisfaction.

I'm not going to blindly believe it because someone says it's real. It would be one thing if this explained an aspect of all the products of every category that I see everywhere - but it's just not the case. Companies aren't in the business of turning down free money, so if the Ikea effect were real then you'd see it in products everywhere. More likely, the theory is just false: that an AB test shows no increased customer satisfaction from token user-assembly, or even decreased satisfaction.

This is why I asked if anyone has, in fact, done such a strictly controlled AB test.
Google is really good at what it does but I absolutely agree with PG that it's not enough. And another startup coming along doing almost the same thing a little better is no good either.

I rather believe, smaller and more niche search engines like zomato(for restaurants in india) etc would get better of google very soon. Like, imagine a search engine for online learning resources with filters like beginners/intermediate/advanced, books, courses, etc; that would be so much better than what google has to offer right now given it indexes a lot of quality resources.
ENGLAND PREVAILS
Also scope, why can I not see some kind of category breakdown, Paris Hilton Vs Paris the city, the fact that the search experience has not changed much over the past years says more about not wanting to break a model that works, as opposed to delivering the best experience for the user.
I actually don't, it was a mistake on my side, I meant isolationism.

This stuff aside, it's a well developed drama with compelling characters and high production values. Even the politics themselves are better than the harrowing status quo in many places.

I just think that people to easily bestow upon it the "best ever" distinction.

edit: As for how it could have played out differently, I'm not sure. Maybe the madame scenes would have been cut altogether? I think The Shield does a way better job with its "McNulty" equivalent.

We took a different approach at my last job when we revisited our entire identity management approach. We were a University with Federated logins across a few dozen system, and our password rules had honestly spiraled out of control because the system hadn't been constructed in such a way to restrict access easily.

During the rework, we focused on a few things primarily:

1. Reduce password complexity, enforce legnth
2. Restructure account creation around least-privilege principal, so that access had to be granted, not just created during account creation, and also allow fast and easy addition and removal of access to system as part of the Management System
3. Revisit password expiries based on level of access and relative strength of password (as determined by zxcvbn)

Students and low level staff loved it - if you had a standard account and didn't have any access to anything sensitive that didn't belong to you, your password could sit untouched for up to 2 years I think if it met the strength requirements.

Those with access to actual sensitive data (student records, finances, etc), were held to a higher class of password complexity and would suffer a rotation penalty if they didn't have a sufficiently complex password; this mostly did away with the number of people with very common passwords, though it didn't go without a lot of fighting for some of the administrators, which, as I remember the discussions anyways, were more pride issues than anything. We used that as an opportunity to roll out password managers
> creating a digital scarcity to act as functional proxy for human productivity, thus money, is hampered by every new shitcoin

This seems contradictory to me. Anyone can create a cryptocurrency like Bitcoin. If people exercising that ability hurts scarcity, is there really any scarcity in the first place?

It sounds like you want to simulate scarcity through a gentleman's agreement, but it's not clear why the the creators of these "shitcoins" would cooperate.

I always say management is they easiest job because you only have four things to do, and I'm sure your team has more than that to do:

1) Provide Air Cover

2) Provide resources

3) Provide direction

4) Get the F* out of the way

Don't over think it. Empower your teams, trust them. They'll make mistakes just like you do. It's not how bad you F* Up it's how well you recover.

Originality in mistakes is the best I can ask for. Let's learn, progress and do better together.

I've been in tech for 35 years, if you think you've seen it all, you haven't and neither have I, so let's figure it out together and get some S*t done.

I think my favorite (hard to choose, there are so many) story line in The Wire is that of Ellis Carver. You have a character who, at the start, views the community as a war zone and himself as a soldier.

Then within S3 and S4 he learns that a cop needs to be part of the community; he needs to know the people he's policing, and they need to know him. There's a great scene where he starts to chase down a group of hooligans and stops short, realizing "I don't need to chase these kids. I know their parents. I know where they hang."

Theres even the parallel with his former partner Herc who sticks to his soldierly ways and is eventually disgraced.
“Ad-driven systems can only reward attention,” Mr. Williams says. “They can’t reward the right answer. Consumer-paid systems can. They can reward value. The inevitable solution: People will have to pay for quality content.”

I for one am willing to do this, and I do already (NYT, The Economist).

The question is, how many other people will voluntarily pay to receive content they don't always agree with?

Maybe we'll end up with a system in which only wealthy people can receive factual, balanced news? (Silicon Valley types: by "wealthy" I mean top 50% not top 0.1%)

Sort of like we have a system now in which, by design or by consequence, it's more difficult, logistically, and in terms of price, for poor people to eat healthy compared to wealthy people.
> But in the developing world, it's the normal way of doing business. You bribe a cop to get out of a ticket, you bribe an official to get your paperwork done faster.

It actually has some nice side-effects like cops targeting only the expensive cars, whereas if you're on a cheap motobike you can pay a $1 for a ticket. Having lived for a while now in a country that fares very poorly on the Corruption Perceptions Index, I prefer it to living in the US.
How? As long as it is not piracy, how are they affected?
I hire for attitude and aptitude.

If you have a great attitude and you're able to learn then you will be amazing on my team.

It's impossible to say "hiring only the best". Because where are these "only the best" people? I've been smashing keyboards for 35 years, does that make me "only the best". Nope.

What makes an amazing team is the ability to learn, adapt and solve real world problems at scale together.

Not "only the best".
A.Meessen suggest a simpler explanation. Dark matter is made of electrically neutral elementary particles subject to scattering and a pressure. These particles may combine and dissociate which accounts for drak energy and the cosmological constant. The properties of all elementary particles (except mass) are predicted by his space time quantization (STQ) theory. It provides a blue print of all elementary particles. It predicts the neutral elementary particles that may constitute dark matter. There is no need to call back in question Newton's theory.

I definitely note single dropped frames when at 60fps (visible by the graph) in fast action games like CS and they do detract from the experience.

Right and my assertion is that because the whales are incapable of understanding their "sacrifice" for their species they are simply kept in a state of anxiety, trapped in a too small enclosure for the remainder of their days and THAT trumps any argument built on vagueries about the potential conservation benefits. I'd much rather spend all the money used in housing these whales on field studies and establishing conservation zones in the actual environment.
Lots of people have already commented on the accuracy of the content, but, as a life long resident of Baltimore, what struck me was the dead on accents.

Baltimore has a very distinct, but evolving sound and vocabulary. Cinema usually can't seem to escape the 1960s "hon" cliche. I was certain that Idris Elba had to be from Baltimore until I learned otherwise.
> The solution was to get out the egg of the dry mixture and allow people to add it themselves.

I'm no foodie, but wouldn't dehyrdated/dried eggs be far less appealing taste and/or texture-wise? If not, why don't we see them around grocery stores? It seems like it'd be great to have non- or even just less perishable eggs.
Not just on airships, but running transports without zero on board staff might have added benefits and efficiencies. I know that in Vancouver the Sky Trains ran without on board staff.

If the airships can be run like transit in Switzerland then the costs of traveling through airports can be removed.

<rant>
Adding six or more hours, or more days in expensive hotels if the dates and times are bad which they usually are, to air travel and all of the new hassles is less and less worth the bother. Having to arrive 3 hours early, lining up early to check-in, possibly paying for and trusting the airport with larger baggage, lining up again and going through security, lining up again to board the plane. Queuing again out to the runway. Do all of that again when you land. All of this with the possibilities of flight delay, cancellation and other changes that airlines will foist upon paying clients. I think travel should be like riding the bus, you show up, you swipe your phone / ticket / pass and go.
</rant>

If done right and at low cost, I would like to see airships displace jets.
If this were true, then an unnecessarily difficult user-onboarding-procedure would make them like the product better.
I'm grateful that there is such a wide spectrum of how to interpret the ambition of these companies between yours and the parent post's comment. Thanks :)
Did I miss something? I see nothing on this list that touches on mentoring or growing. I do see a line about firing underperformers. I've heard a metric that it costs between 2.5-5 time annual salary to replace someone. Sometimes an under performer is just in the wrong role, or on the wrong team; when this is the case they probably know it. Ask them!
I don't think they directly relate. The premise of the paper seems quite an interesting one and anything that can encodes prior knowledge about the objective function while improving the convergence rate is always welcomed, particularly when it is expensive to evaluate.
In terms of my original comment I was referring to standard Bayesian Opt (GP) and my experiences with convergence rates when optimising applications. In these algorithms the kernel underlies the accuracy of future predictions and it is important that is reflects the configuration space. For the majority (if not all) applications the parameter space will consist of continuous and categorical parameters. It is vital that the kernel or choices of kernels over various dimensions encodes the structure of these encoded variables.

My favorite part of the show is the Baltimore dialect. If you are casually watching an episode or two for the first time, there is no way you can grok all the nuances of the local diction. Over time, you start to re-hear words, phrases, pronunciations, and slang and you feel like you are in on it. Then you realize, the diction is different across the regional characters. Sometimes, even the characters can't understand one another.

This joy of language combines with the fact that surveillance and eavesdropping play such central and indeed titular roles in the show. You then mix in the racial element for example having the black office secretary translating street hood lingo to the white cops listening in. It just all fits together beautifully.
Makes sense. I think your approach is a good one - mix passion and practical.
