I don't think the people here are engineers in the class you reference generally. (Though the password and JS crypto posts may contradict that.) I think more content would be specific methods that each classes uses, their overall use flow, what's covered or not, the general state of site security, why people get targeted, etc.
It doesn't matter really what 'Mozilla Persona' is. All that matters is that instead of implementing GitHub login, which is a single identity provider, sites should focus on implementing a global solution to login now that a viable one is available.

The general concept here is that the user just needs an email address and a password to login to any site. I'm tired of having to remember a bunch of usernames and passwords, aren't you?
>This is not what selling stock in an IPO is because stock is not non-existent. You are committing a No True Scotsman fallacy by trying to redefine the term to fit your needs.

Wait a minute, you looked up a definition that used the specific term non-existent to bolster your argument, then accuse me of warping the definition?

In fact, there have been a variety of "Ponzi Scheme's" over the years, some of which have used stock, bank deposits and land.

>Case in point: You don't know the difference between company net income, returned earnings, and dividends.

Huh? Okay.

>Why? Did Zynga falsify an annual filing or their 10-k? No? Then the SEC doesn't give a shit.

I was talking about your statement, which is that:

"Whether or not they bought a lemon is the fault of the public investor."

Completely false, mainly because the public information is provided by the company. By the way, the SEC has looked into Zynga.

>I'm not going to go in circles with you on this any longer.

Good. I'm sure it's been exhausting for you, looking up all these finance terms on Google. Between the arrogance and personal attacks, you're not adding much here.

If this was true there would be proof in the numbers but pretty much all indicators point to this as increasingly incorrect (unfortunately). In America there is increasingly less mobility from the "poor" to the rich and if monetary desperation was an attribute to business success in the current business climate the numbers would tell the story.

If the point of the article is to suggest that having to eat can make you work your ass off out of fear - sure Ill agree with that one but that doesn't mean your business is going to be taking off.

Its also not that hard to understand that the more your back is off the wall the more power and freedom you have to leverage to make smart decisions. I guess if you are just a lazy person desperation may help you get to work but otherwise I cant think of any successful business person who is looking to become poorer so they can get their spark back (and if that is the case, Ill be glad to help)

I was surprised too, when I learned this technique, that people weren't already doing it. I think it's just an age thing. B-trees are old so they have all the kinks worked out, at least in mature implementations. Fractal trees are new enough that there are still a bunch of tradeoffs to play with and evaluate.

When you actually go and implement the system, you find all these behaviors that really aren't expressed in the theory. There are lots of things we're still experimenting with. Flushing isn't too hard, if a flush makes another node way too big, you can just flush that one too. We don't allow our cascading flushes to fan out, to prevent latency-style problems, but they can flush all the way down to a leaf. There are some other fun problems around query strategies and concurrency control too. It's definitely a fun structure to play with.
Not in my direct confirmed experience. pthread lib on Joyent's particularly weird version of solaris was f'd hard.
It could be a sample size effect. There are all these old people there, but how many? It may have nothing to do with the island, they may all have just been lucky and had a streak of heads in the coin flip game. This is especially likely since the researchers are looking all over the world for these small pockets of longevity.

Why don't you ever hear about these things in larger areas? Certainly different countries have very different lifestyles. What's different is that bigger regions have a smaller chance of a freak streak of long lived individuals as a proportion of the population (though as an absolute value, you'll probably find more).

I suspect "blue zones" will regress to the mean after these individuals in the study die, but you can never be sure. If they don't, maybe the islands do have an effect (or maybe they started to attract immigrant older people seeking longevity).
What the article itself deserves is a minor issue.

What the HN discussion deserves, though, is different. We as a community can do much better than that. We do, sometimes. We can more often.

Perhaps a challenge for anyone who feels that an article really must have a middlebrow dismissal---

Limit your dismissal to a few sentences, then follow on with a paragraph or two of thinking that goes beyond the dismissal into areas of thought sparked by the subject of the article. What bigger picture might it factor into? What underlying phenomenon may be behind it? What additional understanding can it add for us as a community?

I certainly won't try to speak for pg, but one thing to keep in mind is that this is a good way to approach topics if you're trying to come up with new ideas that have big potential. Merely pointing out the existing problems is the first step. Take the next few as well.
That had lower entropy than spam. Thank you.

Does tinfoil care if I follow popular security standards?
I don't want to overshadow the general point, because I think it has some merit, but one problem I had with the article was the quote, "If I read 10 or 15 interesting articles on different subjects in a row, what’s left of it an hour later? And how substantial can one Internet article really be? Books in comparison seem to have brought me much more." That may be true (it's going to come down to each person individually), but he shouldn't be comparing 10 or 15 articles in an hour (you can probably read more than that) to a book. A book probably takes you at least 5 hours to read. If you read 20 articles an hour, that's equivalent to reading 100 articles. So the real question is, does a book bring you "more" (however you personally want to define it) than 100 articles (or more) from a place like hacker news?
It really depends. Experiments comparing the effects of animated maps and "small multiples" are mixed:

"We found that map readers answer more quickly and identify more patterns correctly when using animated maps than when using static small-multiple maps. We also found that pace and cluster coherence interact so that different paces are more effective for identifying certain types of clusters (none vs. subtle vs. strong)."[1]

"In cases where animated graphics seem superior to static ones, scrutiny reveals lack of equivalence between animated and static graphics in content or procedures; the animated graphics convey more information or involve interactivity. Animations of events may be ineffective because animations violate the second principle of good graphics, the Apprehension Principle, according to which graphics should be accurately perceived and appropriately conceived. Animations are often too complex or too fast to be accurately perceived." [2]

Do you work for AWS as well? If so, I'd ask that team AWS spend less time astro-turfing on HN, and more time documenting your systems, so we can assess these risks for ourselves.

For example, I haven't heard of any precautions taken against a thundering herd of clients retrying requests in other regions if us-east goes down. What does AWS have there? How much spare capacity do you run in each region?
Or you could just reference William Golding.

USB operates on a millisecond clock. When you press a key twice every second, it varies by what? 20 miliseconds? 200 milliseconds? Who knows what Windows does, but millisecond is best you can do. I tried it on real PS/2 and it worked. Close to microsecond.

God says...

walking on the sea.

14:26 And when the disciples saw him walking on the sea, they were
troubled, saying, It is a spirit; and they cried out for fear.

14:27 But straightway Jesus spake unto them, saying, Be of good cheer;
it is I; be not afraid.

14:28 And Peter answered him and said, Lord, if it be thou, bid me
come unto thee on the water.

14:29 And he said, Come. And when Peter was come down out of the ship,
he walked on the water, to go to Jesus.

14:30 But when he saw the wind boisterous, he was afraid; and
beginning to sink, he cried, saying, Lord, save me.

Making God talk with impossible limits placed is like asking Him to do time travel. It's hilarious.

The only compelling use case for this device appears to be for kiosk-esque setups. For the casual user, it seems unlikely to catch on. I'm certainly not going to carry that thing with me, pull it out, plug it it in, open the FloJack app and tap one of those stickers to call my mom. This would be WAY more compelling if the device would fit flush with the phone in some way such that it'd be reasonable to keep it attached any time the headphone jack wasn't in use. I could see it fitting around the backside of the phone, as there's some pretty good real estate that could be covered without interfering with any other function of the phone. Unfortunately, supporting the different shapes of the target devices could get tricky.
I think the issue brought up in the post to which I responded singled out Windows as being specifically difficult to port to, if you use the standard tools for writing native code. This is contrary to my experience, but it's a somewhat common attitude amongst people for whom portability means "targets POSIX". So I thought I'd write a little screed.

As for your other point, it's indeed true that some systems are more like some other systems, and not like others. But so what? If you want your code to be portable, it needs to build on all the targets you support. So you need to do that. Perhaps people assume there's some magic bullet, or secret special thing that you can do? Sadly not, just the usual - work and some forward planning.
Arguably, Persona and Parse more than overlap: the supported user base of Persona is a proper superset of Parse's actual and potential user bases. :)

Persona works with any email address, and it's completely decentralized (albeit with a temporary, centralized fallback for bootstrapping)
Is there no value to a computer beyond graphics and 3D?

It's fascinating to see people who would seem to be aligned with the RPi's goals getting hostile toward the RPi Foundation. Why is this? My (probably wrong) guess on the psychology at work is that it is not the lack of much forward progress in this project (unquestionably, they have made _some_ forward progress by making the RPi, regardless of whether it is "enough"), but it is the idea of "stealing someone else's fire". It threatens people whose devoted purpose is to fight for what they perceive as the impossible: a totally open device or those whose mission it is only to complain about the lack of openness in devices (cf. actually willing to make sacrafices to use an open device). It steals their fire. The more open things become, even if only a little more open, the less they have to fight for or complain about. Their devoted purpose starts to deflate. It's less important.

And I would guess there are also those who just can't stand to see any sort of change. When the "impossible" starts to seem eventually possible, it's disorienting for them.

My understanding of this announcement is that it's directed at people who are trying to port other OS's to the RPi. Having this code makes their work easier. What if I do not use Linux much? What if I am not insistent on using my computer only as a TV set or a game console? What if my usage is text-based? What if I just want to run another OS on the Pi? Would I consider making this userland code available a definite step forward?
We definitely have some of these in the works, and fair point regarding HN not being filled with typical "engineers."

It's just matter of time for Apple to include it built-in. They (Apple) dont see value in it yet, but that doesnt mean they dont have plans. Agree that this will open up a lot of possibilities.
The regions are completely separate datacenters with no shared components. You have to be pretty dense to think that AZ's are completely independent of each other, considering all the services that are shared between AZ's. The AZ's may be separate datacenters, but they have tons of shared tech, which ends up being the main SPOF.

The legend should probably be open by default. It is kinda annoying to keep referring to it, and it hides away in two seconds :)

I also agree that this kind of visualization is better served with having an animation, and an ability to select specific points in the timeline. I like the small multiples visualization, but the individual map view could be better.

I'd also like to add that having the year show up on hover only is another pain-point. It should be rendered below each map as well.
Only if it is event-based, otherwise you will have a hard time getting people through the door. If it's just a normal store, then it becomes a "Pay to demo items you would still have to buy". That's a little too focused on "How to we monetize?" before you even have customers.

If you are really set on a BnM store, focus on the phenomena of customers trying or touching goods in the store, and then looking up that same good on their phones to purchase online at best price.

For Example:

Your store could host a variety of gadgets, and the digital price tag shows the best Amazon price. Customers then touch and try the item, and if they want to make a purchase, they scan a QR code or NFC sticker with the purchase URL. That URL then contains your referral code, and you get paid through Amazon if the customer makes a purchase. Replace Amazon with any other online retailer that allows affiliates.
Pi Crust: Connect things to your Rasperry Pi
Could anyone with access to HN comments voting data execute something similar to the SQL query below and evaluate the results?

The idea is to use past voting correlation with other users to sort the comments.

declare @userId int;
select @userId = UserId
from users
where Username = 'pg';

/* Let's calculate expert table first. We will use it to rate comments later. */
select
v2.UserId,
sum(v1.Score * v2.Score) as VotingCorrelation
into #expert
from CommentVotingLog v1
inner join CommentVotingLog v2
on v2.CommentId = v1.CommentId
where v1.UserId = @userId
group by v2.UserId;

/* Now we can rate comments against #expert table: */
select
c.CommentText,
(select sum(v.Score * e.VotingCorrelation)
from CommentVotingLog v
inner join #expert e
on e.UserId = v.UserId
where v.CommentId = c.CommentId
) as Rating
from Comment c
where c.ArticleId = 4692598 -- or another article that's discussed
order by Rating desc;

I assume CommentVotingLog table has CommentId, UserId of the voter, and Score that voter gave to the comment: +1 for upvote or -1 for downvote)

I also assume that CommentVotingLog table has at least one record for every comment -- the author of that comment gives Score = +1 to that comment.

These queries don't have "freshness" adjustment (older comments had higher change to get upvoted, so their rating should be somewhat downgraded).
I'm sure he's referring to the RDS outages, and the multi-AZ RDS's that didnt fail over properly. Many of them didnt fail over properly because the issues was EBS...where all the RDS live...

Just like many have said on here plenty of times before this outage. Dont just rely on multi-AZ to be your DR while in AWS. Leverage the other regions.
No problem. Glad you enjoyed it!

"Stop treating errands as burdens. Instead, use them as time to focus on doing one thing, and doing it right. Errands and chores are essentially rote tasks that allow you time to think. They function to get you away from your phone, the internet, and other distractions. Focus and attention span are difficult things to maintain when you’re focused and attentive on X amount of things at any given moment."

This is a great point. It's exactly why I've never liked suggestions to "automate" chores, and I've never felt a huge need to use services like TaskRabbit. Too much of life is already dedicated to the pursuit of productivity. Going to the grocery store is one of those little tasks that gives you room to breathe. There's a relevant quote by Thich Nhat Hanh that I like a lot:

"While washing the dishes one should only be washing the dishes, which means that while washing the dishes one should be completely aware of the fact that one is washing the dishes. At first glance, that might seem a little silly: why put so much stress on a simple thing? But that's precisely the point. The fact that I am standing there and washing these bowls is a following my breath, conscious of my presence, and conscious of my thoughts and actions. There's no way I can be tossed around mindlessly like a bottle slapped here and there on the waves."

I come from a near by island and I had heard some of the facts about people in Ikaria before reading this article (eg that they do not wake up ealy) as well as some more that I did not see mentioned in the article (eg I have been told that they do not lock their stores, they just leave them open in case anyone needs something).

I would really*very much AND strongly like to give a hint to all those who are skeptical about this article that they should consider that a vastly different way of their life can very well exist. You do not HAVE to be a well educated smart hard working entrepreneur to exist on earth. People existed well before that and will do for some more time (if our "civilized" "modern" world does not succeed in destroying our planet.

I would also like to point out that the western world (especially the "civilized" world) has actually failed in the FUNDAMENTAL HUMAN NEEDS, ie food and sleep. Having lived in a place where organic food was the only food I am sick and tired of seeing people eating "healthy" food which in fact is nothing more than a company's new product.
How about a "middlebrow dismissal" link to complement the flag link?

Of course, it doesn't need to be called "middlebrow dismissal" but there is nothing better for determining if something is or isn't middlebrow dismissal than users.

TBH, the flag link could be more powerful/useful by asking people to explain why they are flagging something. Later on you can release the categorized flagged post dataset for others to train an algorithm against. If someone is willing to spend the time to click on flag, they are demonstrating that they care about post/comment quality and that is itself a good indicator that they'd be willing to spend the time to tell you exactly why they are flagging something.
Rocking!
I understand what you're saying, though i think the characterization of startups as a lottery is a mistake. There is some luck involved with startups but smarts and execution count far more. But for lifestyle businesses too I just don't buy the argument that being broke is a great asset. It just makes it more likely you'll fail. Ask anyone who's tried opening a store or a restaurant. It's better to take a job and save some $$ before starting and having some runway. If the writer is going for the narrower case of a consulting or contracting business then founder is misleading, or at least being used in a very different way than most HNers are using it.
