I've always felt that increasing the number of use-cases for Bitcoin would be the key to establishing Bitcoin's intrinsic value. When everyday people think to themselves, "I need Bitcoin to do X", and X is something real like signing into a Web service, then people will finally understand the need for Bitcoin.

Building on top of Bitcoin is the easiest and simplest way of accomplishing this, because otherwise every new app has to build and maintain its own blockchain in a low level language like C++. In which case, core Bitcoin development gets increasingly fragmented and everyone and their mother has an altcoin that then needs to be marketed on its own right to miners and to the public.

While it's true that the Bitcoin blockchain would grow in size if more apps built on top of it, the Bitcoin blockchain will grow in size regardless of what anyone thinks or does. It's already 15GB, which is a far bigger burden on consumers than what they're used to.

There's always a huge backlash amongst Bitcoin developers whenever someone tries building anything on top of Bitcoin. Timestamping or notarization? You'll get yelled at for the mere suggestion of including this "trash" in the blockchain. Very, very unfortunate IMO and a huge mistake by the Bitcoin development community.

I honestly think it's because they'd rather stick their head in the sand about the blockchain. The fact that the Bitcoin blockchain is growing faster and faster disturbs them because it means not everyone can run a full node on their Macbook. I don't think it's any reason for concern.
While certainly not a startup I manage an altcoin pool and DDOS seems to be a big deal in this space. In fact my pool (http://awesomehash.com) just got his this morning.

It's a really bad feeling. Our miners really have no reason to stay with us. For a majority of them, as long as the servers are up there's no difference between pools. If our servers go down, even through no fault of our own we stand to lose a bunch of our members, and who knows if they'll come back.

As for solutions, we implemented a few new iptables rules, and we ended moving from DO to another VPS provider who has DDOS mitigation. There really isn't much you can do.
This is what politics are fundamentally about ~ people organizing to enact changes they feel are right in opposition to those with other opinions. There's no use in arguing that people who operate within businesses are somehow immune from politics. Just as he has a right to have his own opinion and to speak on the subject freely and openly, the rest of us have the opportunity to disagree and organize against him for his beliefs, whether in the sphere of the economy or not.
This is a solid venture backed company that has been generating quite a bit of revenue for some time now. This exit will provide its investors with a solid return. Odd how little attention a company like this gets from the tech community.

Bernie Brenner, the guy who heads up their business development, wrote The Sumo Advantage which one of the best books I've read on BD. He very clearly identifies the role of BD and how it is distinctly different than sales. I'd recommend it for any startup looking to partner with large established businesses to spur growth.

but...being unable to control your body's reproductive rights does make you unequal. You're being discriminated against by having other beliefs forced upon you and your body, much like gays are discriminated against by having a different sexual orientation. Anti-abortion lobbying strips women of their reproductive rights and promotes inequality.
ASP.Net Identity 2 is just that, easy and extensible membership.

I don't know about easy, but it definitely doesn't look simple, judging by examples.

http://blog.iteedee.com/2014/03/asp-net-identity-2-0-cookie-...

There are a lot of abstractions that don't represent anything outside of the framework itself, and a lot of components that interact in non-obvious ways. Also, it seems like finding integration points requires quite a bit of knowledge about how Identity 2 works.

The fact that there doesn't seem to be a coherent set of definitive/official documentation describing what and how it works doesn't help either.
Google has Google Groups which interfaces with usenet. Also, the nature of "waves" doesn't fit with threaded communication model of usenet. It can be made to work, but you'd need many waves/wavelets to accomplish that, and going back and editing previous stuffs would create a confusing set of messages on Usenet. Would you post those to usenet? Post it by replying with a diff? It'd require a very different model. Far easier to integrate standard web forums with usenet (which I, personally, think would be awesome) than what Wave had. It was really designed around a collaborative document model. Would've been awesome if the invite system hadn't been so clunky, and the year delay between announcement and when my friends finally got access just killed any momentum at the time (for me).
Get ready for "exclusive contents" from every single provider or hardware manifacture. Soon you will need a Roku, Apple TV, Amazon Fire TV, Google Chromecast, Hulu, Netflix, Xbox Live, Amazon Prime and many more to access media.

There should be law to avoid this. I shouldn't have to buy Netflix to buy House of Cards.

I expect it will obsolete ICANN as effectively as AlterNIC, New.net, OpenNIC, etc.

The technical fact that it is blockchain-based really doesn't make much difference as it's incredibly unlikely to be adopted worldwide, due to the network effect of the already-established domain name system.
The Username Is a Relic. Here’s How to Fix It
I would say documentation and presentation are two big things you can put effort into having your project seen in a good light.

Also once you have that in place, its critical you get it in front of the right audience. i.e. talk to weekly newsletter guys or personally email influential people in the javascript (in your case) that are looking to try new things! Listen to their criticisms improve and iterate. Also empowerer people in your community of developers one man shows frameworks can start off well but don't last very long without building out a community.
It's hard to generate high quality error messages with current generators unfortunately. More common nowadays is building first with a generator and switching to recursive decent when it becomes too unwieldy.

Hmm - if your ISP has a good DNS, and has a cache hit on your DNS request, versus if you have to seek your HD, the DNS might be much, much faster.

http://www.eecs.berkeley.edu/~rcs/research/interactive_laten...

Round trip in same datacenter: 500,00ns.

Disk seek: 4,000,000ns.

You have to lean on the numbers pretty hard to make the DNS faster, but it's possible it could be faster than your local disk.
Thats a wonderful idea. Two great points that resonated with me:
1. Having a commitment that forces you out of bed.
2. Involving yourself in something that's not your regular normal "world" can be so refreshing.

I would like to try this at some point. But I don't how I would start finding a job like that without contacts. Any insight on that from the OP would be great.
Attacking High-Frequency Trading Networks (2011)
I still remember that page. As a middle schooler who didn't know anything from anything, it was a perplexing thing. The site's got an xxx at the front, but looks like a legit government site from wait, Los Alamos? Like from "Surely You're Joking Mr. Feynman"? Oh jeez, I'm gonna get in trouble with the school...
Why I rank my friends
HFT as you read it in most stories/comments is trying to imply is what Mark Cuban is hinting at in his blog post that also made the front page. Being fast or having low-latency does not make you a bad person. Using those advantages to front-run books or other "tricks" are what people imagine when they think of HFT with a negative connotation.

A firm simply unloading thousands of shares in 100 block increments in a number of milliseconds with very low latency technically would be a bunch of "high frequency" trades, but that type of activity is not what is being debated.

If Microsoft's entire child-security protections don't work; I'd say that's fairly major. What might have been a very compelling feature for parents has been shown to be ineffective (if your kids know about the vulnerability, which for young children is admittedly unlikely).

They paid him at all, which is good, but it also shows that there's no reason they couldn't have authorized a bigger payout. It's still, at most, $350. Why not free Xbox Gold for life instead of one year? There's no cost to Microsoft.
In the early 90's my girlfriend was into CR. She was also into supplements. No one that I've ever known took so many vitamins, minerals, herbs, and antioxidants. She ordered them in bulk in powdered form and made a mess in the kitchen mixing them up every day. Of course, now there's evidence that heavy doses of vitamins aren't beneficial and may actually be harmful.

As to the calorie reduction, she was quite successful in controlling her diet. She ordered guar gum in 50 lb sacks (from Tic Gums), mixing it with water to have something in her stomach when she was hungry. She seemed to settle into a routine that I don't think I could have tolerated. She didn't ever look anorexic, but had very very low body fat.

She was very afraid of getting old and this motivated her. I think that without some sort of pharmaceutical breakthrough that controls hunger, the rest of us will not find CR practical.

You don't have to say much. For example, my wife will ask 'is there anything I can do?' when I'm having a particularly bad time, and while the answer is often just 'no,' her asking the question that way acknowledges the fact that I'm struggling without putting me under pressure to come up with an answer. For me the most important thing is knowing that someone is available without feeling that they're waiting on me.

Chronic depression is a bit like an old AM radio; you can mitigate the lousy signal with the tuning knob and moving the antenna around, but you can't fix it and call it done; the station that's clearly tuned in today might stay clear tomorrow or be mired in static. As a patient, one can learn to separate oneself from one's mood, so that feeling miserable doesn't have to be attributed to an objective exterior cause. But learning that takes time, and inability to distinguish between one's emotional and the quality of one's environment was a major problem for me when I was younger.

The most helpful thing you can do is be around to listen and allow the depressed person to vent without pushing them to identify an actionable solution, frustrating as that may be. Asking questions can also be helpful, to inform yourself about what the other person is experiencing. For example suppose you were talking to a blind person; you get the basic idea of being blind but you don't know what it's like, so it's quite reasonable to wonder, say, how the person chooses groceries or decides what clothes to put on in the morning. When depression is chronic one develops a variety of coping strategies (which work more or less well at different times), and articulating that sort of thing often helps me get out of a trough and recover my sense of agency.

One other thing that's very common for people with depression is muscle pain, because the inner tension is often mirrored by a physical tension. It's hard to describe, but the physical tension can even act as a focus for the bad feeling. A backrub or a neck rub can go a long way, if the depressed person is feeling up to it. Other times one may not want to be touched and is better off just going to bed or somesuch.
It's funny that this is what people claim the want (unbundling)! Basically, if unbundling ever really happens, you're going to be paying the same amount of money for 20 channels as you currently do for 200.

A law is not the answer.
Pushing back against the bullies
Of course I'm not saying that it's extremely frustrating both to have click fraud and having little data from Facebook to better understand what's going on. I totally agree with that.

However:
1) I don't think Facebook would be so stupid to intentionally fraud on clicks ... the damage could be much bigger than the gain. I'm pretty sure this is mainly due to click farm, bots and so on.

2) I don't care about the click fraud. I don't advertise to get clicks. I advertise to get customers. As long as the overall CPA I get from Facebook is lower than AdWords I'll keep advertising on Facebook.

AFAIK nothing other than PHP or Perl has ever produced "winning" blog software.

Rails is actually not a great fit for mass-market blogging software, though, because it doesn't have very good support for theming.
You said, "it's that the theory doesn't have a lot of support"

I was simply pointing you to a reference that showed that "academics" use the exact same language regarding chemical balance of neurotransmitters as the original author.

Notice that it didn't say, "Academics disregard the chemical balance explanation because it lacks evidentiary support."
Any comments on what the issues with SAS were? Performance? Interface?
So the guy supports a law that was passed. Doesn't that mean a lot of people who care about these things agree with him?

I find it difficult to believe this article. Any confirmation?
I put them together because they're news items on financial shows/periodicals. I am not confusing the two (yes one is illegal, the other can do good). I apologize for the unintended obfuscation.
Some aspects of HFT seem highly analogous to insider trading to me, and insider trading is currently illegal. Abusing the ability to cancel orders fast in order to ping for non-public data about other orders sure seems like an insider advantage. As I understand it this "pinging" is central to HFT strategies. Am I missing something?
2013: $134M revenues and $25M loss.
I think you're simplifying too much. The example being repeated in relation to the book and IEX is you have a 100,000 order, 25,000 displayed at the same price, say $10, on each of 4 exchanges.

You might think you can fill 100,000 @ $10 and allegedly many people did. In fact if the exchanges were consolidated into one you would be filled.

It seems to me a displayed order should be able to be traded and not behave in a seemingly prescient way by disappearing when the order is made.

In an ideal world would the latency between exchanges serve any beneficial purpose?
Ask HN: What's the best domain you own that you aren't currently using?

The cheap digital antennas can work pretty well (depends a lot on your location but worth a try; HD, too).
We do have a CAPTCHA too before the block. Basically to get the block you have to really work hard at it. We also do not mind limited robot use for cases like downloading all papers given a search term or author but we do not want people downloading our entire corpus either. So throttling is not an option.

I think the case mentioned in the article is definitely heavy a heavy handed approach. When it comes down to it at my place we are just trying to block the wget -r's of the world.

SDN: Do Network Engineers Need Programming Skills?
One of my apps accesses a persons' contacts. The approach I took to this was to notify the user ahead of time that I would be asking for permission to use the app, and that we would never use the contacts for anything but in app convenience. It feels great and is very informative. Only thing is the code is a bit wiry, but I'm working on that.

I'm really starting to dislike our society, because gone are the days when you could have your own opinions and viewpoints. It may not be illegal to disagree with the majority, but you will be shamed/boycotted/treated poorly to the extreme for it.

I don't agree with the guy, but who cares? That's what an opinion is, and unless he donated company money to this cause, which he didn't, I really don't think society should be allowed to judge him, as a professional, based on his personally held beliefs. I don't know about everyone else, but I tend (more like strictly do) keep my personal beliefs and work life completely separate.

How many soldiers died to give us the freedom of choice, only to wind up with it being a complete illusion. You're allowed to believe something, only if no one on the planet knows that you in fact do.
I already backed! I highly recommend this project!
Complete idiot's guide is right.

Exchanges offer price-time priority. A 'better' price (higher bid, lower offer) gives you priority over a 'worse' price. Given two orders at the same price, an earlier order gives you priority over a later order.

If you spend millions of dollars on computers, data feeds, and salaries to skilled personnel, to predict the motion of markets correctly and work within the system to make money, then you've earned that money fair and square. Companies that don't operate within the rules get shut down fast and hard by the SEC and/or FINRA. This is a highly regulated and policed industry.

HFT is hardly different from Warren Buffett identifying a company with a 10-100 year time horizon. Should we penalize Buffett because he's smarter and better at that game than everyone else in the world? Is he scamming the person from whom he bought shares in 1984?

As Knight Capital showed us two years ago, you can spend those millions, and still screw up and lose $10M per minute for the better part of an hour until your firm is bankrupt. No one is guaranteed to make money.

Posting an order and canceling it is fair game. When the order is in the market, it's a live intent to trade. When it's canceled, it's no longer a live intent to trade. Why is this "moral" when it's a person doing this on a time scale of seconds or minutes, but "fraud on the market" when it's a computer doing it on a time scale of micro or milliseconds? If someone hits that HFT computer's bid, there's an obligation to fill that order - nothing is different about such an order just because it's placed and canceled quickly. The only objection is fear of the unknown. And the only difference here is that it's being done based on an automated strategy, faster than people can react. Your broker has access to HFT tools. Your 401(k) manager has access to HFT tools. If you're a day trader, your order is probably being routed through HFT tools.
"Unbundling" is completely stupid. Be careful what you ask for because you are going to wind up paying the same amount for your 20 channels as you do now for your 200. That's just simple business and economics. The marginal cost to deliver you a channel is zero.

What market risk are the scalp-style of hft strategies (not all hft's are scalping) taking ? If they can cancel orders at abandon and make pennies if they win the race (against other hft's), but can simply x out of their order if the price doesnt go their way is as close to a riskless profit as it gets.

What valuation are they shooting for?
Even Manoj Narang conceded that he noticed the same thing as Brad Katsuyama around the same time: lower fill rates. The lower fill rates only led to scratching of heads. It was the underlying cause of lower fill rates which led outrage (in Brad's case).

The underlying cause is the "perverse incentive" (Lewis's words) of the taker-rebate (reverse of the usual maker-rebate taker-fee). Is there a sensible reason to such a fee structure? Or is it just useful for HFT firms to bait orders and get an informational edge they can exploit against mom & pop's retirement fund?

The same should be asked about esoteric order types (Hide-n-Slide, Post-only, etc). Its cleary a complex landscape with middle ground, but it would be surprising if there weren't cabals and conspiracies hiding in obscure corners.
