My kids learned to tie their shoes this way from this site and never knew differently. They're 20 and 17 now.

I made my own simple multiplayer 2d game to understand this stuff and just want to let you know that your site was invaluable to understanding client side prediction and server side reconciliation! Thanks so much for that!

How about airborndocs?

Yeah, I don't understand this. I read the FTC complaint and it hinged on the issue of collecting the data w/o explicit user consent, ie a pop up or message. Wouldn't nearly all internet companies fall in to this bucket? Ie, log aggregators, analytics SDKs etc?

This is how I got in to MtG, and can confirm that its super fun. If you're lucky enough to find a group of friends that will participate, don't let the opportunity pass you by.

This is one of my favorite DF stories bar none. The last time you posted it here and I read it, I laughed so hard and showed it to so many people.

Since then, I lost the link and forgot the terms to search for it! I'm so glad you reposted it. =)

Same for us

Can't launch instances in EC2 in US-East-1 at the moment.

Awesome. Thanks! Again, very clear. This is interesting stuff. It makes me curious about applications of stochastic processes in general - time to read the course notes you linked. They look like fun problems to program and model.

Edit: Wikipedia, of course, has a good overview of applications of Markov chains. http://en.wikipedia.org/wiki/Markov_chain#Applications

Thank you for the clear explanation.

In a previous comment, I sought to further understand how the Lottery possesses the Markov property. Based on your definition above, I can see that it does simply because the distribution X_t of winning numbers has the same dependence on X_{t-1} as it does on X_1, ..., X_{t-1}, that is, zero. Do I have that correct?

I'm interested in the above article and the above two comments, however, I don't understand the Lottery example. Can you clarify how it does have the Markov property?

I'm not seeing how the distribution of possible winning numbers relates at all to the current state. I'm trying to phrase this in the language of the above two comments. Help me out if I've got it all wrong. =)

This is hilarious. I voted yesterday and Snowden had 99% of the vote. He deserves to win.

Someone should conduct a real, independent poll an award a POY award from the Internets.

I love how simple and relevant the idea is - great job!

infinite { repeat(10){ = while(<128){+}++ >=^ = while(<128){+}++ v } v }

What if some percentage of the torrents there were used to transmit secret information?

My Dad, a physicist, taught me that game as a kid. I have great memories of him producing a pen at any restaurant we might have been at, and he and I passing any waiting time playing sprouts on napkins or paper scraps. I since play it with my kids.

Got a link? I can't get enough bike.

This kind of valuable feedback is why I like HN so much. It's kind of you to take the time to organize and share your thoughts, asimjalis.

This isn't uncommon in the python community for long running processes - especially those that frequently that create large amounts of small objects. An application server sitting in front of mongodb does exactly this. It forwards queries to mongo, then pymongo json loads the result for you, the application server does what it wants with the objects, then json dumps them to serve to clients. The json loads/dumps calls create tons of objects and memory bloat. The GC cleans them all up, yet memory isn't returned to the OS. See here:

http://effbot.org/pyfaq/why-doesnt-python-release-the-memory...

In my tests of python 2.6.6, 2.7.3, and 3.3, python 2.7.3 was by far the worst in hanging on to memory. Yet the performance increase (due to integration of simplejson) is worth the memory penalty. We use gunicorn with sync workers to serve our WSGI app and a memory watchdog to signal the worker to gracefully retire after it handles a query large enough to leave it with a large memory footprint.

Performance has been awesome and we're very happy with the result.

We must work in similar industries. We had, and scrapped, a project do to nearly exactly what you are describing. It felt like this was the next logical step for us: we had experience in hardware, embedded linux, android and have good relationship with prominent distributors.

However, it was still a big big task and we'd never get close to competing on price/quality. Also, we discovered the same thing when talking with schools, they were letting students manage their own and adopting new policies to regulate their use.

We're focusing on software now.

How is security handled for this service?

This may be against twitter's ToS, but can you create a bunch of accounts with different API keys to access the api concurrently and get around the rate limits?

I'm sure twitter must account for this, but how do they? You don't need to provide much information to get an API key.

I find that the same quickcheck style testing is the fastest way to get out quality code for a project that I am the sole devleoper of.

I usually code in a terminal running screen with many shells going, one of which is running ipython so I can interactively import and test snippets, classes, or small functions that I'm writing in a larger module. It works great.

However - those tests disappear! Once a recent project of mine was handed off to a team for maintenance and more features, I found that, in particular places, where the code was subtle, it was subject to breaking by others who were just trying to fix something unrelated. This was when I, personally, realized the value of unit testing.

Yes, its slower and takes more time up front, but if your code may someday be worked on by others, it protects the sections of your code that have test coverage against breaking - which over a longer time scale can save time.

Yikes, I feel like the last person to hear about PSY and Gangnam Style - great song! 126mil views (original), wow.

Edit: the mashup ruled. More plz

"It took just a couple of minutes."

This is why I like the business.txt idea. Microformats or microdata, however appropriate and simple, are still one level of abstraction above this idea.

I came to this post 45 seconds ago, looked at GH, and could explain what this is for and how it works. That's saying something.

This.

Its not about whether you can build it, of course you can. Its about choosing to build things that solve your core problem. Time is money, and your money is best spent on the original aspects of your idea that do not already exist.

I'm glad this is on the front page again. I just set mine up. thx internet.

Wow, great show HN! Works very smoothly on Mac OS 10.7/Chrome. I'll bookmark this and use this myself as well as send to colleagues for sure. nice work.
