Funniest joke about a tragedy was told to me and others by a friend's wife about 20 minutes after the friend died. It was very near the worst day of a group of people's lives and we really needed to laugh because it was going to suck for a long while.
The use of the word 'worse' is misleading. The article wanders. I do not feel it is worthwhile.
It also may mean that there is some recurrence relation in a sequence that

For example, the Fibonacci sequence, taken modulo 3 repeats every 8 numbers:

1 1 2 3 5 8 13 21 34 55 89
1 1 2 0 2 2 1 0 1 1 2

That makes it easy to answer such questions as "What is fib(3567^368857) mod 3?". Just compute 3567^368857 mod 8, and be careful to do the lookup right.
Maybe add an "other CS-related" and "not CS-related" fields ?
Is it too broad for a subcategory of theoretical computer science?

While it may have made sense in the pre-Mir days, it made none whatsoever on missions that serviced space stations. Knowing the extent of damage possible during ascent would have changed the rules by which shuttles operated.
Populations grow exponentially, and the whole population is required to pay into SS.
I'm curious how you formed your opinions on the safety of nuclear power:

What publications and which experts did you find authoritative?

Have you reviewed any academic research on the subject?

Do you understand the arguments of the pro-nuclear viewpoint?

Show HN: pyDash – web dashboard for your Linux PC/server in Python and Django
I built this with the raspberryPI in mind and tried to make it using python modules available in the main distribution.

More or less a week-end project for fun.

Should work fine in Ubuntu, Debian, Centos and Fedora. Might work on others as well.

Still a work in progress :)
Oh, I was supposed to put down my job? :( Oops.

Agreed. Giving someone full access to your bank account is very risky. At least with credit cards you can always dispute charges and it is the merchant who is usually on the hook, not the consumer.

When most people vote for one category, voting for more than one makes a mockery of the whole process and just makes it even more pointless than these polls usually are. Better would be to ask people to spread ten votes around the places they feel they have more focus on. Those that have a single point of focus could put all ten votes on that, people like me could spread them around accordingly.

To accurately reflect my "main focus" I should vote about 15 times for math and then spread votes liberally around the others. Instead I shall abstain.
sounds like a real ass.
Aside from the fact that yes, pair codes are annoying - it sounds like you didn't understand Sync at all and were upset that it wouldn't compromise basic security guarantees for ease of use?

In the old system, the pair code was effectively a password. It's obvious that resetting the sync key wiped out your synced data; the synced data was encrypted with the old key and generating a new one obviously wouldn't let you decrypt it. (It's possible the old key can still be used to recover the data, but I'm not sure).

Complaining that it demanded a pair code is like complaining that gmail asks you for a 2fa code after you've turned on 2fa. Of course it does, that's how the security works.

Of course, the pair code system is kind of a pain, so they introduced passwords. But the pair code system does work if you use it correctly. I don't think it's fair to call it 'completely borked' when your problems are entirely down to user error.

Keep in mind that Firefox Sync always protects all your profile data; Mozilla can't access it because your machines encrypt it. This is unlike Chrome's profile sync where all the data lives on Google's servers and is accessible to them. As a result the authentication can't be as simple as 'sign in with your gmail account' or something like that.

Hey Abeiz, would love to chat with you about your experience if you have time, you can reach me at george@codecombat.com.
Good point, I guess I'm still new to this, I just bought some BTC from the new Montreal's ATM yesterday.
I guess that by blacking out the time or part of the amount I would have made it "uncertain"...

So yeah, point is, it's true, ponzi.io screwed up big time in my favor (and I just got the 6th verification).

And ... it's Saturday, and I've just got some "money" for free booze.

cheers! ;)
Finally! The tedious way Firefox Sync used to work is the main reason I use Google Chrome.
The payout system does not seem to be FIFO, that is, just because you put in money before person B does not mean you'll get paid out before person B. I also put in 1BTC (far before these people) and followed it up with a small transaction. The small transaction got paid back (also incorrectly) whereas my 1BTC was never returned. Oh well, it was fun to watch.
I run a software startup producing a SaaS product for communities.

Traveling Salesman Problem...
Will this algorithm work?

Algorithm:

1) Take a square space and divide it into 4 squares.

2) Find all 94 quadrilaterals that the 'nodes' can form.

3) For each quadrilateral, that has points in common with the original, do recursion (I.e. go to step #1 for each of the 94)

4) Keep repeating until some minimal square size (resolution) is reached.

Find the path with the shortest 'Error' and that's an approximation to the traveling salesman problem.

'Error' is defined as the sum of the distances of all travel waypoints to the nearest quadrilateral path line.
Live tiles, arranging my start screen to show exactly what I want without having to open any apps, I think is the single biggest feature that I love about WP. I also love the text prediction and correction when typing. I haven't seen any other mobile OS do it as well.

Android and iOS are pretty much one and the same for me. They do similar things and they come stock with a very similar UI. I'm not big on the list of icons/folders and multiple pages setup.

Regarding ios7, I don't like the new text-as-button thing they have going. It's hard to find them sometimes. I also really dislike the difference in pre-ios7 apps and ios7 apps as far as UI goes. It's jarring to me. It'd be like having a windows XP window pop up in Windows 8, or an OS9 window pop up in OSX.

I am also not a fan of the all-caps ios keyboard. Windows Phone keyboard displays the characters exactly as they're about to appear, but in ios they are always capitals (just differently sized) and it makes for a good bit of errors for me. I still have an ipad with ios7, so I interact with it second-most of all mobile operating systems.
I also have a Lumia that I use as a secondary phone. The device is nice, Nokia can surely make good hardware, however my problem is the OS.

The Metro UI is kind of nice, but it gets obnoxious. I've began to hate those animations. And when I do need in-your-face notifications, like for the weather or something, you don't have the nice widgets that you get with Android.

Also, Microsoft is in charge of the Facebook app and I don't get how in the world they managed to treat the login in that Facebook app as something separate than the phone's accounts. I also want to be able to manage what accounts are synchronized or not - because synchronization uses battery, plus notifications are annoying and for many accounts I only want to view the latest messages or whatever only when I open the app - and haven't found an option for doing so, unless you turn the battery savings on. While we are on the subject, the notifications bar is a joke.

The app store is full of crap. Microsoft has played the app numbers game, allowing some genuine crap in their store. Of course, both Google Play and iTunes are filled with crap, but the search and the ratings are usually enough for finding good stuff and both Google Play and iTunes also have very polished, very good apps for everything.

But the above don't really bother me as much as my last point - Windows Phone is at its core as restrictive as iOS. It does not allow installs of apps from third party sources and is basically defective by design ... for example, to do Wifi tethering, the mobile career has to wire you the settings that allow it. And it's been a PITA for me, because my mobile career couldn't wire me the settings automatically, since they don't have my phone model in their database. Isn't that awesome?
Consider, for example, calculating binomial coefficients mod a large number.

It's not hard to realise that C(n,k+1) = (n-k)C(n,k)/(k+1) is one way to write the binomial coefficients. So if we want to compute C(10^10,50309) mod 10^8, for example, we only ever really need to carry numbers mod 10^8 around. And since (ab) mod c = (a mob c)(b mod c) we can avoid obtaining really large numbers and can safely hold them in unsigned long ints.

Since this problem is counting things, there is mostly like a recurrence-type relationship to it and at each step you would take the result mod N. Many combinatorics problems are like this. Although if you've only done 60 PE problems, then the ones in the 400s somewhat implicitly assume you've done the previous 400 since the ideas do built up.

Great read. But I was disappointed that it didn't mention other password encryption schemes, i.e. Blowfish.

Ponzi/Pyramid schemes often are honest about this. What they are usually not honest about is the mathematical impossibility of it being possible for it to keep going very long. But some simply bet on people being greedy enough to take the chance that they are getting in early enough...

As such I think it is good commentary on Bitcoin and cryptocoins in general - a lot of people do appear to enter expecting a pyramid, and just hoping to get theirs before it collapses.. The question is what proportion they make up.
That article says nothing about preloading pages. The speed gains are purely a UI thing -- if you're clever about keeping submenus open even when the mouse leaves the submenu's entry in the main menu, you don't need to provide a delay for menu opening/closing.
I agree that foregoing the rewards is a fairly big assumption and it might not be realistic. But I do think there are other advantages and will write about those. The I don't think people will (or should) absorb the merchant risk and that's why someone does have to take up an acquiring bank-type role (and charge for it).
This is probably not a popular view, but I don't really understand why comments are viewed by some people as a bad thing. I agree that useless, redundant comments are not helpful. But that doesn't mean all comments are useless. I don't agree that well-written code never needs comments either. Reading the code tells you what it does. It doesn't always tell you why it's there.

Digging through version control comments seems to me a last-ditch effort to figure out what some code is doing. If the project had any significant history you could be digging through hundreds of commit messages. Why not just put a 1-liner comment above that line and save every subsequent developer the hassle of wondering what the heck that seemingly useless line does..?

Agreed on both counts. They (e.g., Coinbase) will likely have to do this, and charge for it.

Do you use (client-side) encryption for ensuring privacy?

Otherwise, I like the almost (share buttons) minimal design.
Anyone who doubts that Social Security is a Ponzi scheme should try starting a similar one themselves, and see how it goes.
I believe the larger merchants (e.g., Overstock) may not even be giving refunds right now. When buying with Bitcoin you can only get store credit.
No worries, it's not clear at all what you're supposed to put down. Personal focus, professional focus, aspirational focus, academic focus, general interests, hobbies...? I'm not sure. The list provided isn't really a good fit for any of those things.

It's not an accurate poll that should be used as a good model of reality. Just a way to have an idea: you mostly care of the order of votes, not the individual bits.
I'm curious, how do you securely implement client side encryption?
Open source is not for end users you are right. Fre software is, its where I as user would expect to have root by default on my own phone. Its a huge difference.
I have a few ideas:

- should work offline

- realtime updates visible to other parties, so it would be usable as chat

- history

- align editor size to browser window size, so there are no two vertical scrolbars

- even better is to grow editor window as documents grow, use only browser vertical scrolab

- https, useless for me otherwise
See, it is not like that. Even if he was selling the game he would have to wait for at least a month for Apple to pay. And since this is advertising, it can take a lot longer. Also, he can have problems getting the money into Vietnam or wherever he is. He may get a large US cheque, which will be a huge pain to cash.

As the two other comments here state, 20% is nothing to sneeze at when you are a low margin retailer (which many are). And I think 20% is the low end of possible savings (I'm the author of the post) - it's possible that the savings will end up being significantly higher, especially if retailers can keep some of the money in Bitcoin (because business partners start accepting Bitcoin and/or volatility comes down) and if fraud costs come down.
It really bothers me just how heatedly pernickety some users are.

WoodenChair, your request for calm is greatly appreciated.
How so? No one is being deceived. Everyone who participates does so of their own volition. Is individual volition repulsive?

Are they really dumb? Is the guy in the middle of the scheme who makes out with a profit dumb? There's known risk - some will decide they'll risk it. It may not be wise (I wouldn't participate, myself), but I wouldn't be so bold as to assume they're dumb.

> But those who participate are still morally complicit.

Who are these morally complicit participants if not the "obviously dumb" persons whom you just described? Are they victims with "serious issues" or are they morally corrupt enablers?

You may mean that the morally-corrupt-enabler(s) are whomever set this up, but that's not really what's suggested by such a broad phrase as "those who participate".

Thanks! Could you explain what you mean by using direct links?
So you advocate doing things you find morally objectionable while telling yourself that it is the right thing to do because you can give the money away afterwards? That sounds insane to me.
Interesting. You and another commenter on the article are making me want to try this. I've definitely noticed better energy levels through the day when I eat small quantities frequently, but I agree that it can be a lot of work. I've never tried the once a day thing. I'm skeptical, but it sounds intriguing enough to try...
Love the idea of realtime updates. Thanks!
If I were running a startup like youtube or airbnb should I open source? The problem of clones seems to be quite big (they all already have clones).
you can find a number of shaky-cam amateur examples on youtube of them. I'm quite surprised that there isn't some googlable drawing of the thing in a textbook-quality form - you know, like http://outreach.atnf.csiro.au/education/senior/astrophysics/... this - but instead for sunstones.
Mind blower #2:
How many different shapes can a brain with 4 neurons recognize? 94. Evolution of vision neurons actually would have started out using a "chance built" circuit that could solve this 94-item 'recognition' problem. Then the DNA that solved the 94 would run repeatedly to recursively form the rest of the retina, giving the brain higher resolution, but using only one 94-pattern-solving DNA recursively. I think the major advancements in neural nets will come about once we start "wiring up" brains in interesting ways like this rather than the current "layer training" approach...The brain is recursive, and needs recursive wiring to be simulated.
I'd personally say it fits in theoretical compsci.
It's a good question and also needs to be answered. I'm the author of the post and have one coming on the consumer side.
Currently, this isn't implemented.
I second https and history (I already commented on dynamic layout).

Offline would require some work I guess but it is still a good idea. However, I tend to dislike realtime webapp as they are always trying to sync sending HTTP/WebSocket and throwing errors around whenever one packet is lost.
But it still had tiles, right?

The disappointing part is that he apparently has such poor self-esteem, he thinks that he will not be able to create anything more popular than this game, even with all the money he's generating.

Regardless of what he builds, what industry he is in, there will always be people there to criticize. Why throw away opportunity that most people wish they had due to something that will occur regardless of the revenue?

Being a martyr only works in certain circumstances. This is not one of them.

> This is unlike Chrome's profile sync where all the data lives on Google's servers and is accessible to them.

This is not true. When you configure chrome's sync you can set an encryption password separate from your Google password and select items for encrypted sync.

Though in my opinion Firefox Sync had the better method here security wise.
Look at [1]. They suggest using this:

<a href="https://twitter.com/share" class="twitter-share-button" data-lang="en">Tweet</a>

I guess it relies on the HTTP referer field. You can do more resilient by adding parameters to the query string (look at the table at the third of the webpage).

It means that the user gets redirected to the website with pre-filled forms. It avoids loading additional Javascript.

Really awesome. I was working on something like this myself, but using Jquery ajax combined with history.pushState for partial page loads. This is much better!

There are a couple things that I had on my TODO list that could be handy though:

1) Caching - if you hover back and forth over two links, it will keep loading them every time. Dunno whether this can be alleviated or not.

2) Greater customisability. It'd be great if I could customise whether it was a hover or mousedown preload, on a per link basis. Some links benefit from hover, others it might be overkill.

3) Lastly, it would be cool if it could link up with custom actions other than just links. For example, jquery ajax loading a fragment of html to update a page. This is probably lower down on my priority list though, as the full page prefetch works remarkably fast.

Keep up the great work!
It works fine for me on nightly Firefox on Linux.
“CPU Limit Reached” :(

I don't think it's still as simple as entering your username/password if you don't have your paired device nearby: you also need a recovery key. I got bitten by this once: I didn't remember entering, or even being asked about a recovery key when I set up my account, so I was forced to reset my data. Luckily, I still had my bookmarks in Chrome, so I didn't lose any data, but the entire experience was frustrating.

Also, quick addendum: you _can_ specify an addition password in Chrome so your data is encrypted before it gets sent to Google. It's pretty much identical to FF Sync then, and much more user friendly.
