Draftin' has entered its third beta release! I would like to take a moment to thank all of the Beta users who participated in Beta 2, you all have been a huge help in finding issues with Draftin' that I did not find myself. In Beta 2, you guys/gals uncovered an array of bugs which have been patched, along with usability issues around user interaction and menu/GUI simplicity which have been fixed/updated.

Anyway, I have been taking a more community oriented approach to Draftin's continued development. Basically, I am letting the users give large input as to what they would like to see in Draftin', and I have been prioritizing development based on that input. Beta 3 is entirely community driven, consisting of all the most reported issues/bugs. Hopefully Beta 3 brings a much more well rounded and bug free drafting experience!

Beta 3 contains the following updates

- Add flashing tab on various events throughout Draftin' if user is on another web page/tab.

- Play audible sound on various events throughout Draftin' if user is on another web page/tab.

- Fix UI issues in My Cards section where card rows are out of sync.

- Make user profile display users cards. If you ever leave a draft/the coordinator deleted the draft, you can now retrieve your last drafts cards from your profile.

- Greatly improved Set selection UI.

- Fix server error when users try to join the same draft twice.

- Fixed issues with kicking users from a draft.

Anyway, that's all for Beta 3. I am calling this update a usability update as it touches on the main issues you all found in Draftin'. I hope everybody enjoys the updates and continues to help push this little MTG draft simulator towards dev complete!

If you like this tool or have suggestions then feel free to leave them here. :)

They don't list any pricing, I wonder if they provide it for free with the caveat that you have to have a Skype logo and mentions.

If you had to prioritize these, which would be your top three?

Mine are "Search across multiple attributes", "Ranking" & "provide real results from the first keystroke", in that order.

Would be great to know what everyone else thinks, so we can improve our service accordingly (https://starthq.com - Greplin-like cloud search).
Please comment if interested
I agree. The original analysis made some important points, and the response by Zidisha was great too.
If people couldn't pay to co-locate with the exchanges they would still compete for latency reductions. They would try to get in the building across the street. Or the one two blocks away. Or the one with a direct fiber connection.

Being able to pay to co-locate with the exchange actually serves to democratize things because it puts everyone on a level playing field where they pay the exact same cost for the exact same access.
I used it for a day or so, but it was just too slow and clunky compared to Sublime text. I'll come back to it in about 6 months and give it another shot.
I don't whats silly with this. I agree that most products where you put data, there should be a search. Not always, but in most cases.
ug sorry my reply was poorly worded. the parent post said "or support abortion and keep his job". so yes, you cant compare that as support of abortion is in favor of giving women the right to control our own bodies, unlike prop 8 where it was taking away gays right to marry.
I've had only iPhones until this year, my only tablet is an iPad, I work on a Macbook Pro 17''. Last month, I got a Nexus 5, because the screen (4.95'', 1920x1080 pixels) is just so much better. I can read ebooks very comfortably on it, it totally replaces a Kindle for me. There are apps like Calibre Companion which I don't have on iOS, and there are no apps on iOS which I miss on Android (except my own :-)). Before I got the Nexus 5, I thought the iExperience is still too good on mobile to be matched. Now I think Apple should be very very VERY scared.
Frankly I was blown away a little while ago when I first used the new search, it's lightning fast and really finds whatever you're searching for. I'd really love to know more about the infrastructure behind.
As an SF renter, this makes me happy. I have met too many people personally that have an extra bed room(or even keep their lease and moved to a lower-rent city) that they rent out to subsidize their rent. This reduces stock for actual renters and drives prices up.

Probably not since you aren't the one profiting, but if you know that it's illegal for the host, you probably shouldn't do it just to avoid being a jerk.
But people only think it's unfair because people like Michael Lewis have done such a bad job explaining it to them!

They think that HFT makes them materially worse off when it, in fact, does the exact opposite. We should just cave to that misconception?
That looks great. I think they experimented with this idea on reddit aswell at an early stage. However it didn’t turn out to be beneficial. I unfortunately don’t know the details, I read about it in some comment on HN a while ago (I unfortunately don’t remember where exactly).

There is definitely a sweetspot. I understand 4 inches is very small for any mildly serious task, it can be done but it's painful. But IMO 5 or 6 inches don't feel so liberating. It's better, but not that much, and at the end of the day I really want an iPad to do any task that will last more than 5 min.

For people who usually have a carry bag, an iPad is not so big or clunky. Having a 4 inch phone to pocket is then good enough.

What is this Skype thing you speak of? I can't tell if that's the burning of cash or planting a tree... since that business unit will likely be decent on paper until it becomes pretty great on paper. I mean who would be using some voice/video calling software over their existing data connections instead of paying for per-minute land line rates through their telco's?

Also, for enterprise & institutions using Exchange, many seem to be loving Lync, etc. for IM+ services. Skype seems like a decent long-term play. Also, good for the IP.
k is the output index (the "bin" in the frequency domain), or the notch in the rotated space in that graphic. Every output frequency coefficient contains a full sum of the input function, hence a direct translation of that formula is O(n^2) -- which is why the FFT, with O(nlogn) complexity is so important.

The graphic doesn't really help show how the analysis itself happens, it just presents the result, which is a series of waves that add up to f. The actual process of obtaining a frequency coefficient from a time-domain function is easy to describe: multiply the function by a (co)sine wave with a particular frequency and sum together the result. But it's not very intuitive why that works until you consider that one period of a sine wave sums to zero. By multiplying the sine with the function, you perturb the shape of the sine with just the amount of energy that the function contains at that given frequency. So that instead of summing to zero, the sum measures "how much" of that particular wave is present. That's Fourier analysis.

Fourier synthesis is more easily visualized (I think anyway). Simply multiply a sine wave at each frequency by the corresponding coefficient derived above, and sum those weighted waveforms together elementwise to recover your function.

Well I for one am shocked that usurers are engaging in usury.
This is literally an advertisement for Algolia masquerading as an article. They literally went through each feature their product provides and listed it out. Going to their page, the animation is practically a point by point repeat of the "article."

Maybe it's okay because it's a YC company that it's also posted here, but it really just leaves a bad taste in my mouth.
REST is a set of constraints for building a system. A RESTful interface is one that cleanly abstracts the underlying data store into one that is simple to use for third party systems.

It's important to understand that a RESTful system doesn't necessarily expose a true model of the underlying data store. You could have an invoicing system that contains Customer and Invoice models. I see developers confusing that to mean "you have /customer/ and /invoice/ endpoints and never the twain shall meet". If you need to embed customer details into invoices and/or invoice details into customers, then feel free to do that if it makes sense for your application.

There's more to it than that, and I've mostly just described how common HTTP-based RESTful systems work. Fielding gave a lot more detail in his thesis: https://www.ics.uci.edu/~fielding/pubs/dissertation/rest_arc...

I'd recommend reading it, as it helps clarify a few things. Also read up on the term HATEOAS, which details how information should be interlinked where possible, so your system can be (theoretically) crawled for more information.
I don't think I understand the point you're making in your first paragraph.

For your meteorology example, if such information didn't have life or death consequences, I might call it fair. But the contexts of the two scenarios are different. The stock market is inherently a bet on future prices, and so using information obtained by yourself through your own efforts cannot be seen as unfair--it is an expected property of the system. Using HFT techniques to profit off of frontrunning your demand is unfair. The "market" for items needed for survival isn't analogous.
I wonder what the rights of a short term renter is in SF. Lets say 30 days or some other small fixed time that is legal. Can you practically stop paying rent and live there for the years it takes to get you evicted? Would they have to pay you the $~40k relocation payments to get you out eventually?
>>>> Curious why you think this is. Do you think people really aren't pushing the boundaries today like they did back then?

Not at all. The law hasn't just caught up, it's like a boot on the throat of the people trying to push existing technologies to new places and uses.

Just take GeoHot. Guy jailbreaks the PS3 and all hell breaks loose. Sony says they're going to patch the way he broke into the system. Then GeoHot says he's writing firmware to go around that. Then Sony sues him, then Sony wanted all the users who watched his videos on YouTube. Then Sony finally settled out of court after he agreed not to hack any more Sony products.

All this because he wanted to run some custom software on his PS3.

There are definitely people out there seriously pushing the hacking boundaries, but my point was the consequences have gotten way out of hand. When I hacked the university email system in 97', I got my network privileges revoked for a year. What do you think the punishment would be nowadays?

You're just not able to hack for fun anymore since anything you do could be construed as a crime, and a serious one at that. Even a guy using his neighbors wireless service is now a federal crime.
For most of what I want to plot, I find ggplot code faster and easier to write than base R graphics (and prettier, but that's subjective). This includes using ggplot::qplot for quick one-off plots.
I keep reading Skype Texas.
True, but probably the solution is not yet another third party who does the same thing as every other third party.

Obviously it's still a problem, but the problem isn't just "I need someone to do this stuff if I die". Rather it's "I need someone I can trust absolutely to this stuff if I die.

By trust absolutely I mean:

* will not abuse it.
* Will not even look at the data I submit and can guarantee this.
* will not get hacked and/or can guarantee my data's security if they do get hacked
* won't get bored with this hobby. Which leads to:
* will be there in 1, 10, and 50 years - or can 100% guarantee orderly step down if they don't make it.

More basic short term considerations that also are not addressed by this or any other service:

* what if their server is down or under DDoS when I try to confirm my living state?
* What if I can't get to a system and miss multiple emails?

These services are a good idea but there is a lot to be done before they can be considered as solving this problem.
I bought deadmansswit.ch a couple of years ago and started building something similar to this, at least in terms of the "do something useful when a period of time with no contact had elapsed", but none of the "do something useful"s required needing your credentials for anything.

Domain is freely available again, I gave up on the project and rolled the useful code into something else.

Two keys, you put one on memory sticks which you give to friends/family you trust.

In the event anything happens to you the other key is sent to those people allowing them to decrypt it.

Service can't access your data as it only has one and same for trusted person.

I'm sure something like this already exists (and tbh the level of effort required to set it up pretty much makes it unlikely to catch on) but it is theoretically workable.

While breaking the law is generally a bad idea and generally one should be punished for it, I was disappointed that both the article and comments on the article didn't delve into whether it is a 'good and fair' law in the first place.

I understand the ambiguity of a tenant virtually subleasing a property, which is a clause normally either allowed or not allowed in a tenant's lease, but the blanket ban of renting a room for a short number of days seems like a law that hotel lobbyists worked hard to get in place.
But if a firm is making a big sell of a stock, as a representative of institutional investors, then it is making regular folks worse off.

Misconceptions should certainly be eliminated, but the fact that HFT firms require colocation does not pass the smell test of fairness. No amount of explanations can eliminate that.
Your definition (in the first line) would imply that closed-source freeware is commercial, I don't agree with that. I do agree that commercial is orthogonal to open source.

So my original point about the license not being properly commercial stands. I do agree with you that it is not really proper to claim that there is a spectrum between commercial and open source.
Someone has explained it here a couple of years ago that VCs generally view them as failures as they have investment pools with lifetimes of 7-10 years and each pool is expected to yield something like a 10x profit at the end of the period. There's not much difference between losing their original investment and getting it back as they will have similar effects on the performance figures of the pool at the end of the cycle.
Especially with all the websites locking zoom! Please quit doing that.

Apple should give Mobile Safari an advanced option to always let people zoom. This way, everyone who locks zoom on websites for the sake of clueless clumsy users are still getting what they want, and people who really need zooming for legibility can get what they want too.

Since you said "Many" (even 1% could be many by some definitions) it is hard to dispute your assertion.

Nevertheless, I think the # of Americans that can point out the US on a world map is well over 90%. I don't see any definitive data to the contrary.
Countless studies point to a lowering in bid-ask spreads (the effective "fee" impatient traders pay to trade) when electronic market-makers entered the market, and an increase in this spread when they leave or are forced out:

http://marginalrevolution.com/marginalrevolution/2014/04/a-s...

For me to win trades as a market-maker, I have to put up prices that are tighter (buying higher and selling lower) than my competitors. Through this competitive process, the rents earned by market-makers decrease and the end consumer of their liquidity reaps most of the benefit. Since markets have moved away from a monopoly specialist model and become more electronic, spreads (and thus compensation earned by market-makers) have decreased dramatically.

Nobody is backing it up because a.) firms involved tend to be secretive so as not to give away any competitive information, b.) there are a lot of slow or inefficient brokers speaking out against it "talking their book", and c.) to the end-user, HFT is like plumbing. I don't thank the city workers every time I hop in the shower, or write a glowing blog post about Visa when I swipe my card to buy goods and services all over the globe. The infrastructure exists and it provides a benefit, but it's faceless and not something most people think about. Most people don't even consider who is on the other side of their trades or where the prices even come from. They just want to click a button and get in or out of a position, and thanks to competing HFTs they can do it instantly, cheaper than ever before.

In Seattle, there was a HUGE stink after the City Council passed a law regulating services like Uber & Lyft. Given that we (Seattle) are always compared to the Bay Area in terms of innovation (and the stifling thereof), it's nice to see that at least our two city governments are aligned in their ineptitude.
It doesn't look like that at all. Microlending loans are a bit different than the "go to the bank and borrow $100K" loans that we are all used to. The bank doesn't charge a fee, because they make $1000s on interest on that loan over it's lifetime and it covers it.

Your bank won't lend you $50 as a loan. It's not worth it for them. But if you add in some reasonable fees (like $11 for credit check report), an $11 one-time fee on a $50 loan converted to APR looks huge! 500% APR! But it's only because the amounts we are talking about are so small.

I think we need to look at this more carefully and not compare apples and oranges. Big loans and small loans are different things.

(And payday loans are evil. But microlending is not the same as that.)

Except for properly licensed hotels, short-term rentals are illegal in SF.
If the internal resistance of the battery really is low enough for this to work then the discharge speed could also be a huge advantage for other applications.

At the same time I see a huge safety issue: If I drop my phone in the water I don't want it to be able to transmit power that quickly.
Yes, an ethereum contract might cost 50 cents to run.

Now try calling some lawyers and ask them how much it typicaly costs to defend a contract in our traditional court system... it will probably be a number 100000% higher than 50 cents.

Cryptocontracts are great for Joe Publics.

Ask HN: How to be altruistic while working full-time?
I'm a full-time software developer at a company based in Boston, and most of the work that I do is backend (python/mongo/data) and is really tailored to the applications we're currently developing

I'd really like to contribute to open source projects but I feel like i never have the time to, or that If I were to contribute I would be spending less time doing work and more time focusing on the projects I'm contributing to. You would say that I should write better code and release code as packages or blueprints, but most of the code is proprietary, we're still validating our products, and if I were to do that I would have to spend a lot more time to add more functionality that really isn't used in my application, and iterations would generally take longer.

My question is this: how do you give yourself time to work on open source projects? do you feel like contributing to open source is better (in some sense) than contributing to the growth of your own company? or how do you make contributions/build open source projects as part of your job?
And why would you want to move 10K lots through the market any others point of view than the HFT traders? It's a genuine question.

This is something I've thought about, and as I see it a lot of the problems common to crypto software are manifest in this space as well. Specifically with regard to security vs useability/ease-of-adoption issues.

This particular implementation transmits sensitive data in the clear and does the encryption server-side, so it's hard to take it seriously except as a remote (and unsecure) notification service.

Aside from that obvious shortcoming, a truly secure and reliable DMS system would need the following properties, possibly more:

1. All data encrypted client side and sent to system only in encrypted form

2. Anonymous

3. Distributed (no single point of failure for DDOS attacks or subpoenas)

4. Any data sent into the DMS system is split into several pieces and only reassembled after the set time without a response has elapsed and the switch is triggered

A peer-to-peer application that transmits data exclusively via TOR would probably be most secure, but it's unclear what the motivation for running an instance of this kind of P2P application would be (since it's all encrypted you aren't downloading anything useful) or how many people would actively participate. Any server-based system would need to have a large number of servers in multiple countries to be robust to technical and legal challenges, and that sounds expensive. At the same time, a reliable and anonymous DMS system is something that I can see people paying a small subscription fee for.

Any way you slice it, it seems like there are a lot of hard problems to solve in this area, but a reliable DMS service would be extremely useful.
I believe they are referring to the use of Cd in displays that utilize Quantum Dots (QD-LED) not regular LED/LCD displays.
Using APR on a maximum $50 3-month loan IS misleading. To compare that to a home mortgage hides all sorts of fees that the lender is able to cover because of the profits they make from interest.

At the small scale, those fees have to be paid by the borrower, making APR a poor metric.
