Yeah, I thought the same thing, once I saw

val bind : ('a -> Result<'b,'c>) -> Result<'a,'c> -> Result<'b,'c>

Because that's precisely the signature of bind (=<<) in Haskell. Although it looks nicer in Haskell. :P

But I do respect the author's desire to avoid getting too mathy and hifalutin with the theoretical stuff, because you can really go overboard down that path...

No thanks. I don't trust corporations like Twitter any more than governments.

All of the dominant American online service already come with their own built-in ideological censorship, usually under the euphemism "family-friendly". (Twitter is actually one of the most tolerant services.)

People can challenge the governments of their own countries quite well, thankyouverymuch. It may take time, but in the end they are a big fat easy target.

Challenging global corporations is a lot more terrifying. So far the only thing that has helped us fight back has been... governments.

Thanks for posting this. For what it's worth, I'm the author of this talk and the one pictured in the video.

I'm flattered it's getting so much attention (I like having my ideas spread!), although there's one thing that confuses me. I've never heard of Hakka Labs, nor did I post the talk, video, or my bio on their site (although their treatment sure looks like I did) -- as far as I can tell, they grabbed it from the site of the SFRails Meetup at which I gave it and posted it online. I'm grateful for the exposure, but some notification or clear notice that I'm not affiliated with Hakka Labs (whatever/whoever they are) would have been nice.

Several, including pg and rtm. The hardest skill is knowing what could be simplified, and what's good enough.
Your scenarios smells wrong to me. Why would anyone pay USD for these seized BTC, then turn around immediately and sell them for USD again? The government is the party dumping BTC on the market. The buyer presumably intends to profit. They would profit by holding until the price goes up, and selling into the market at rates that don't dominate the marketplace.
All companies strive for profits, but some take a more short term view than others.

Actually, I agree with you more than you'd think. After living in San Francisco for a year or two, I'm absolutely skeptical toward 99% of the stuff that's passed off as "Silicon Valley revolutionary" crap. I'm pretty much only interested in pure technology: SpaceX/Tesla, new hardware manufacturing / internet of things, drones, immersive computing, bitcoin (to some extent), etc.

Which is why, I think, I can enjoy the HBO show thoroughly while still lamenting about "where did all the hackers go"
>If your theory is correct, people would hoard any resource that is increasing in value relative to something else.

People do indeed have a tendency to do exactly that. Take gold hoarders, for instance.

>An inflating currency would never catch on. It's a hot potato situation of "I don't actually want to own it because it's decreasing in value. If I do have some, I want to dump it on the next sucker as fast as possible to minimize my losses."

The point of the inflation would be to offset the natural hoarding instinct with an incentive to actually spend it.

If inflation goes TOO high, you will, of course, end up with everybody trying to dump the currency off on to everybody else.

There is a sweet spot in the middle, however.
how do you judge that peercoin and dogecoin don't work out?

They seem to have been the "next big" currency for market cap after BTC and LTC for the last 9 months, which would point in the direction of, at least, inflationary nature not being such a big deal.
One of the reasons U-verse is a failure is that AT&T can't even figure out how to connect customers in neighborhoods it has actually wired. I have been trying to get U-verse for years, even though linemen have called the business office to confirm I can be wired. They cant figure it out. My best guess is that the maps of the physical plant are a complete mess and, at least in older neighborhoods, they can't figure out what is wired to what.

Help me Google, you're my only hope!
What rebelidealist said. In the talk, I try to be pretty clear about what kinds of data are a good case for this kind of storage and what aren't. (In short? Data you only ever retrieve for a single row at a time, and that you never query on. Also, you really need to store it in a separate table that's 1-1 with the main table, or all you've really done is bloated the original table and made things worse.)

My own experience is that there's actually more data than you'd expect that can fit into this model. On the other hand, I am absolutely not pushing this as a panacea: if you don't really know what you're doing, tossing JSON in a RDBMS is probably a really, really bad idea. After all, that's part of the talk -- to discuss when it's a good idea and when it isn't.

(I personally think the low-card tables part of the talk -- http://github.com/ageweke/low_card_tables -- is the most interesting idea.)
The Golden Curve: Determining player value in freemium apps
I wanted a simple way to show friends how to use Bitcoins. Entering an email gets you a single address and a fun animation when you deposit. Withdraws are confirmed via email. Currently the only withdraw method is Amazon credits, but I plan to add more if there’s interest.
Bitcoin got first mover advantage. I don't think its popularity is due to it getting the incentive mix "just right".

Besides, the characteristics of a "good coin" depend entirely on who you are and what your goals are. Some people want to gamble and get rich, others are looking for a reliable store of value, others are looking to transact. The ideal coin will have different properties for each of these people, but no coin will be able to satisfy all three groups completely. They all need one another and they all have competing goals.

I agree. The big-screen control-center examples he gave are for monitoring a mission in real time. The Hadron Collider scientists analyze the data later on ordinary-size monitors.
Its the systematic data collection that is important.
If it was anyone else I'd be a lot more skeptical. There is something different about this guy so he might just mean exactly what we would like him to mean. Mmm hmm, yeah, I'm going to stay positive until proven I shouldn't be.

What % of HN knows what this means? Maybe this should be a blog post instead and explain what a "mining pool" is. Or what is the significance of one pool taking over the market.
as a long time proponent of BTC, this is the first time I'm truly worried. Not that I think GH will do anything 'dodgy', just that it's actually happened and that's not a good thing at all.

GH just did a great job, I think when other competitors step up and provide as good a service - this will become a distant memory of the past - a blip on the radar (I hope).. There'll be a handful of decent pools, thereby never letting this happen again. (I hope again)
> I don't think any of these things are controversial

They are. Especially the first one, which is just a slightly lower-level affirmative action, and a lot of people will use the second one as a justification for discriminatory treatment. The convenience of surrounding yourself with people who are not assholes doesn't magically make all the assholes in the world disappear.

There are people who complain that things like Girls Who Code is discriminatory against men. [1] There are people who complain that the demand for respect is censorship against their right to self-expression.

> I am even more interested in knowing what other people have tried and what worked and what didn't.

Then stop asking people to stop discussing solutions.

Except that a lot of people don't even recognize that a problem exists. Seriously, the "Maven is my girlfriend" slide hit the social media only a week ago.

> I think the impedance mismatch between us is that you are advocating a top down approach through legislation and I am advocating a bottom up approach.

I'm actually not advocating anything. I'm arguing against your "everyone please stop discussing the topic" policy, because it's harmful.

I expressed a willingness to vote on a bill because you expressed an interest in using that method. I mean, really. You can't tell me the action items aren't controversial when you're disagreeing with what you think my proposed action item is right now.
Interesting data point, thanks!
If all the compute power that together forms the GHash pool were controlled by a single entity, this would be an issue. Thankfully that's not the case.

I believe the current skepticism around Silicon Valley's
"Make The World a Better Place" mentality is deeply rooted
in historical anxiety about institutional capitalism.

OT rant here: I don't think this is related to Tesla opening up at all. "We make the World a Better Place" is self-important bullshit in 99.9% of cases. The most likely outcome is that what you are doing has no measurable impact on the "goodness" of the world. In most cases, what you are doing matters only to a tiny fraction of the world's population. "Making the World a Better Place" is simply self-important hyperbole to the extreme.
Certainly; if you can audit the source and reflash the device yourself :]

But that's unthinkable until it's possible to build alternative devices locally as cheaply and easily as it is to buy one of these devices, without such competition we'll never have the choice.

Anyone familiar with Bitcoin is likely aware of the 51% attack. A blog post is hardly warranted, because this isn't significant. GHash.io does not control all of that compute power. It is a metalayer that coordinates distinct and unrelated compute resources controlled by (supposedly) 180,000 seperate entities[0]. In order for a 50% attack to take place the vast majority (at this point) would have to agree to attack, and that simply won't happen.

[0] GHash.io homepage
Why does this matter?

One of the most notorious threats to blockchain-powered networks is allowing a malicious actor to obtain control over more than half of the network's computing resources. This situation is commonly referred to as the elusive "fifty-one percent attack." It is difficult, but not impossible to pull off —http://motherboard.vice.com/blog/bitcoins-fatal-flaw-was-nea... — the aggregation of this kind of hashing power. And it looks like we've nearly made it there again, but there is a difference between a pool getting > 50% of resources, and an "attack."

A successful attack using this method would allow the attacker to exclude, or "orphan" any new blocks from the valid chain causing all newly-minted coins go to the attacker. He may also execute a "double-spend" and reverse any of his own transactions during the window of time that his sham blockchain is considered authoritative by the network.

A successful 51% attack on Feathercoin — http://www.coindesk.com/feathercoin-hit-by-massive-attack/ — was stopped in its tracks by the network's natural uptick in difficulty in response to an increase in network hash rate. The Feathercoin attacker was likely executing a price pump in parallel to compromising the network, which caused coin-switching pools to mine feathercoin and increase the difficulty to a level that stopped the attack.

> I thought thought radioactivity was harmful to all life forms

The ambient levels of radioactivity are very "livable" in the surroundings of Chernobyl nowadays, plus you have to consider that it's not because radioactivity is detrimental that it prevents animals from breeding and surviving. Only very high levels of radioactivity are known to be fast killers, moderate levels will likely cause more cancers, and low levels are heavily debated (some people saying it causes harm, some others saying it has protective effects on the body as it kills a number of microorganisms).

If a company keeps most of its money in a bank, do they "not accept" USD?
this is kinda pissing me off. Melissa Meyer shares no personality traits with Khaleesi, but they are the same because she's the only woman leading a major tech company?

Saying Peter Cashmore is the equivalent of Jamie Lannister is even worse. Saying that one represents the other because they share "dashing good looks, their flowing blonde locks, their square jaws, their piercing eyes" (all of which fall under the category of "dashing good looks" btw) is like when dudes say that this chick and that chick both have big boobs, so their obviously the same, as if they are devoid of personality. Jamie is defined by his skills as a warrior and his DGAF attitude as much, if not more, than he is for his looks.

I will concede though that the comment of Elon Musk discovering alien life by staring idly at the sky one day was pretty funny.
not quite. The scientists didnt like what they were doing and were driven by making sure that thier side was best equipped.

Patent lawyers just make money. Go to trial? Pay up (even if you loose) Need a new patent? Pay up. Want to enforce your existing patent? Pay up. Want to check to see if someone is infringing on your patents? Pay up. The lawyers, more or less are neutral benefactors of the patent wars.
I don't mean to be demeaning, but in situations like this, admitting your ignorance on a subject is a great first step, but the next is learning how to best phrase questions.

Ask HN: Does anyone use a battery case?
Hi all, I'm conducting some product research into battery cases and their appeal. On the surface, it looks a no brainer i.e for minimal weight addition, you get 1.5 to 2 x better battery life versus a regular case or no case at all.

So why don't we see more battery cases in the wild? Is the profile/thickness/weight or simply lack of visual appeal that stops people buying one? Is it pricing?

Would appreciated your thoughts battery cases and your experience if you've owned one.

Can you list numerous countries that are examples of not having a restrictive patent system, and subsequently are bastions of innovation?

The US economy has been an extreme bastion of innovation for 200 years, while also having a robust patent system (one that has only recently become particularly stifling). In fact I'd argue there has hardly been a greater bastion of innovation in world history than the US economy from 1800 to 2000 or so, very few countries compete for that title.

I'm very much not a fan of how the US patent system works today, but I'm finding it difficult to prove your claim based on historical evidence.
