i showed a friend once that he could tickle himself by plucking/poking at the tendon/muscle on your upper inner thigh (pretty much right next to your crotch). he totally had a field day playing with himself.
I truly believe there will be a lot of great information in this course. My only worry is this will be more of a course filled with the insights of Quora-type questions and less of something grounded in entrepreneurship as a science. I mean isn't this course just a survey and not really much of a sound curriculum?

That being said, entrepreneurs who are in b-school tend be a little more risk averse so having a course like this may bring some of these risks (aka dilemmas) to light.
[video] Engineering Scalable Social Games
One thing that CEO Dick Costolo has said is the amount of technical debt we have (http://kara.allthingsd.com/20110117/full-dces-interview-vide...).
The scale is simple tremendous, and you've got to remember: Twitter isn't just a website; it's an SMS service, clients and an API.
Be careful who you take advice from. I can't believe somebody who is providing information on setting up EC2 for startups was not using elastic block storage for their critical data.

There is really no excuse for this. Don't make the same mistake.
As much as I don't really like the "DSL" terminology for anything less than a true language with a parser and AST of its own, the advantage of the Ruby-esque "DSL"/library-with-carefully-chosen-name-conventions is that you are starting from the base of a known-working language. I have a "DSL" I wrote at work for decorating functions with various metadata and recurring bits of functionality like permissions checking in Perl for work, but because it's just not-really-even-glorified Perl I still have the full power of Perl to do things like programmatically generate these functions. Using a recurring set of decorations is as easy as sticking them in a bog-standard Perl array and just passing them as bog-standard arguments in the right place.

It's tempting to replace your language entirely and compile down to something else, but IMHO this sort of thing shows that's a very dangerous play that generally succeeds big or fails big, usually the latter. Incremental expansion of an existing language, even with something as powerful as a syntax preprocessor (that ideally compiles to results that are themselves manipulable language constructs like closures or simple values passed in an idiomatic way), is generally the way to go; most of the win, hardly any of the risk. Something like StratifiedJS or something, if I understand it properly, adding meaningful additional syntax without trying to be its own independent language: http://onilabs.com/stratifiedjs Or, from the sounds of it, the way this language ultimately went.

Javascript may not be quite as slick as Ruby, but, well, to be honest I think Ruby partisans really oversell the value of being able to drop a few parentheses out of your code, and while the block syntax may be nicer JS still has relatively decent closures.
Is there any resource you would recommend to someone interested in learning more? I'm just branching out past core dev and building something where I would like to know more about SEO without having to wade through the piles of garbage out there on the net....some really shady SEO people/information/portals out there!
Twitter.com is probably one of the great engineering feats of todays social Internet.

You tweet from your mobile phone app (maintained by twitter) or twitter.com, and that tweet gets posted on your public timeline. The tweet is parsed for mentions, and it is also copied on to the mentionee's incoming timeline and their mentions timeline.

The tweet is parsed for hashtags, and active searches (i.e. ones open on twitter.com, or via the APIs) and is also copied onto those timelines.

Also, you have followers. So Twitter also copies the tweet onto the inbox timeline of each of your followers.

Not only is all this information published in real time on Twitter.com, but it is also made available via JSON API, Streaming API and Firehose API.

All tweets (on all timelines) are stored forever.

Twitter's scale is hard to fathom - all of this processing is way beyond what your Rails / Django app could process with a MySQL backend. MySQL replication wouldn'e even come close to keeping up with the sheer volume of events to be processed.

To make matters more complicated - Twitter is expected to scale to meet the demand of emerging world events (eg: Egypt, Iran, snowstorms, hurricanes, earthquakes, bushfires). These events don't evenly spread traffic across Twitter's network, but instead provide "storm surges" of localised intense traffic.

Oh, and Twitter haven't just launched an analytics product?

I think for sheer engineering at scale, there are maybe only about half a dozen other companies in the same league.

Thanks. We might be interested in selling if everything pans out. But I'm more interested in how to handle our first contact with this company.
Google's Copying Accusation Called 'Silly'
Open CV is free and decent to start with. Lots of wrappers exist for it so you could pretty much use it with whatever environment you are using. If your idea is validated you could then look into some of the more expensive commercial libraries out there. They would give you more features flexibility scale and (maybe) better results.
"The better example is, you found out where her long-lost cousin lived, some guy eavesdropped, and HE told her where said cousin lived, and she jumped into HIS arms and drove off into the sunset. You are not now without an object that you formerly owned; you just planned to exploit a scarcity of information that no longer exists, and you're mad about it.

You also feel cheated because you were the one that did all the work to find her cousin, and he got all the benefit. That doesn't make it the same as stealing a car."

Risk for Cardiovascular disease will be high by common pain killers
For me college was tremendously fun. I learned a great deal, formed life-long friendships, and generally had the best time of my life.

You won't get that at a job.

You'll spend most of the rest of your life at a job. Take a few years to experience something different.

Besides, you've demonstrated you're smart and capable, so you'll have plenty of bigger, better opportunities come your way.

Go to school. Enjoy life. Talk one of the firms into giving you a part time job instead of full time. You'll get the best of both worlds.

I'm not entirely sure I see what he did wrong -- he says he was using 'block storage', but his remedy was to get an EBS volume?

Was he really running the contents of two websites on the EC2 instance?

I mean, I've done that. Once. When I was first playing with EC2, and well before I'd actually deployed a live and (apparently) valuable site to it.

If I'm understanding the problem correctly, then my sympathies. I don't know if it's a curse or a blessing that it went all this time without having rebooted and destroying everything before now. I suppose that's the sort of thing you'd prefer to learn earlier than later.
... 'Overall U.S. Smartphone Subscribers [that can't update their phones]'. I am really tired of my new full time job trying to maintain my outdated $500 Android phone with is non-functioning GPS. Samsung is a shitty manufacturer. I don't want to run their stupid Kies software... but I did. Samsung Galaxy S is not capable with VM fusion. I don't own Windows native machine. I can't sync my phone, I can't update my phone, It locksup and freezes, the GPS doesn't work, I can't copy and paste, it's filled with bloatware and crapware, and on and on and on. I really can't wait to get my iPhone back. I shouldn't have to void my warranty, invest hours hacking hardware, and risk bricking just to get a working communication device. Just to repeat a recent stat 'Android users running newest version 0.4%. iOS users running the newest version 90%.'
These Are Facebook's New Offices
I went to college for one year, left to work for 3 years, and then back to school. Obviously, no right answers. However, take into consideration that when you do come back after a few years, all your friends will be out of school, and you may find your new classmates a bit young (you'd think to yourself, "I've already done A, B, and C, and now I need to deal with this crap??" :-) ). At the beginning you'll feel a bit out of place, but then you'll find the crowd you want to hang out with. If you only take 1 year off, I think you'd be ok :-)
QFT "Never underestimate the motivating power of boredom."
Why not just plug it in at night? Or, are you trying to limit the duration of your charges?
At least in my area, it's hard to find clients that are willing to pay even the baseline functional rate of $100/hr. I just took a job well below that, and most clients balk when I suggest it. I just had a guy yell at me earlier this week because he thought $100/hr was outrageous (after repeating several times that the program he wanted was going to be "very complex"), and he said he would go to India before he paid that kind of money. I told him "good luck in India" and to give me a call if it didn't work out; while I need the work, I know better than to take clients like that, especially if I have aspirations of scaling to a reasonably-sized firm one day.

I've found that most medium-sized companies are practically impenetrable for consultants around here; everyone has a contract with Robert Half, or has a policy against contractors, or doesn't want to pay anything above $50/hr, which is barely acceptable for a single developer, and practically useless to someone trying to run a company.

I'd really like to know how I can get my foot in the door somewhere where the client won't balk and I won't feel like I can't charge the full time because the company is always talking about how strapped they are. It seems that nepotism is the only way to get in there without resorting to dirty tricks.
Jeez, is there anywhere Wayne Sutton doesn't show up?!?? That guy is truly a social media superhero, I tell ya. In fact, I'm not wondering if this whole post isn't part of some elaborate viral marketing thingamabob that Wayne is orchestrating...
Yeah -- if I'm understanding that article correctly, he really had no business offering up advice on how to configure EC2 instances.

On the upside, the title is decidedly not link-bait. That really is the biggest mistake you can make on AWS.
Hiring Cofounder
I'm hiring a second co-founder who is knowledgeable in PHP/MYSQL and is an ex Google,or Facebook employee. This is the 10th time I've posted this request on Hacker News just going to keep posting it until someone listens. I'm building a website and I have 104 lines of code I was thinking we could trade off the work until it is finished. Meaning that since I just wrote 104 lines of code you would go write 104 lines and pass it back to me and we would do that back and forth until the website is finished. I'm working to have the Beta out by August. If your interested email me @ klownkeeper@gmail.com or tweet me @KeithClark_ thanks!

Wow, how strange.
Actually, that's why I carefully stuck to phrasing it in evolutionary terms. I have no idea what AIs may or may not arise, but if the situation has spun this far out of human control regardless of how there may very well be a "species" of robot that desires to eat humans, it won't last long against its robotic competition.

Plus the other robotic competition probably eliminated the humans, anyhow.
I agree; my bias was to try and control everything (including lots of legal docs, in our business) with SVN. But it turns out ... "people who can't [or won't] figure out version control" amounts to just about everybody who's not a dev, in my world. There are lots of those people and they're important to my success (and, dear reader, it is likely, also to yours).
Congratulations! Never been in this situation, but I tend to be the suspicious type :-) I'd be careful, if I were you, and make sure they're not just trying to size you up and get info about your business (maybe they want to start a competitor? maybe they want to see whether it's a viable business how much traffic you're getting, and then decide whether to buy you out).
Paranoid? Maybe. Only the paranoid survive... :-)
the few core features of the video seem generally unnecessary. automatic data binding on multiple clients and auto syncing with offline storage is cool- but not really imperative for most apps to get started (which is where tools like this will shine).

that said, the project is obviously young and i obviously know very little about it, so i am interested to see how it develops.

that said, this is a problem many have tried to solve (without writing their own language), and (imho) failed. backbone is (imho) taking the first step in the right direction. to be clear, i am not comparing lunascript to backbone directly. they seem to be two very different solutions for the same problem.
I'm almost certain I don't have the time to be a co-founder, but I'd love to contribute.

My email address is in my profile. If you're not inundated with offers, drop me a line.
$100? I'd rather pay $72: http://forre.st/storage#sata
This should work now. I can't verify how accurate it will be, as I don't read or speak a language with a Cyrillic alphabet, and there were quite a few modifications to the algorithm that had to do with English text only, but you'll at least get a result back at this point. Let me know if it's at all accurate!
I love how people here are promoting college when the richest people who ever lived never went...Milton Hershey dropped out in the 4th grade and I've never met any female who hates a Hershey bar!

"1984 successfully vaccinated a lot of people and helped stop certain diseases of the mind from spreading and causing more damage to civilization."

You're still just coming up with synonyms for "got them to do what I want."

I'll thought experiment you back. If 1984 were largely ignored, would you still think it worth reading? You claim that this book influenced the behavior of a world ripe for totalitarian domination. That's a big claim in and of itself, but let's let it stand for the sake of the point I really want to make.

Basically, you care about 1984 from the perspective of its effect on a bunch of people you don't respect (you think their "minds" are weak enough to need "vaccination" against a "disease"). Even you are treating it basically as a remedial text for political idiots. You don't even mention anything you got out of reading 1984.

So, if it weren't effective at convincing people you don't respect of your viewpoint, would you care at all? Would this book be worth reading if you were the only person ever to read it?

That last is my measure of quality, and 1984 falls short - sure, it's an important cultural phenomenon, but I could have reaped the benefits of the cultural phenomenon without ever reading the book.

As someone who is currently in college and was in a similar situation as you. I ultimately chose to go to college since I felt I only have one chance to get the true college experience.

I do not regret my choice at all, I feel the connections and memories I have made are invaluable to any job offer I received coming out of high school.

Ultimately the choice is yours and do what you feel is best for you now and what will line you up for a successful future.
Most people, as they grow up, learn the difference between what is moral and what is legal.

Chin up, champ, you'll figure that out someday, and maybe the appropriate use of condescension too!

However, one the great parts of Dropbox is that you don't have to pull new changes--they're automatically updated on your computer as soon as someone else changes a file. With Git, you'd have to remember to keep pulling the new information as needed.
So Paul Carr has no fixed address, he only lives in the finest hotel suites.

From the article: Even more impressive is the money Carr saves. He does all this cheaper than you’ll be shelling out to live in your own gaff. How? Well, there’s no mortgage, no bills, rates or fees. To put it simply: no worries. If you look at hotels, you don’t have to worry about maintenance or any of that stuff, Carr says. You don’t pay council tax, you don’t pay line rental on your TV, you don’t pay for breakfast... if something breaks in your room you just phone down to reception and they fix it.

So what's preventing the rest of the population from living only in hotels the way that Paul Carr does?

> Have they not heard of Betfair, which has been allowing this kind of thing since 2000?

Is Betfair really the same thing? Everything I heard about it while reading about prediction markets made it sound like the Vegas bookies that Cantor is being contrasted against - a limited set of bets run at specific times. Not arbitrary dynamically-generated bets at arbitrary times in the game. To me, that's quite different. Like the difference between a video game which is a shooter on rails, and _Halo_ with decent AI bots fighting you.
That's a good breakdown of the processes but I am positive all that is done in stages and queues.

So with a good design you have groups of servers doing the different stages in the queue.

One you've got the pattern down for 100 tweets per second, the pattern should be reproducible by scaling servers in each queue to 1000 tweets per second, and eventually 10,000 tweets per second.

The database requirements may explain why it's all done in one datacenter instead of trying to do replication across the country/world.
P2P anonymization is tricky. Making it scalable means that each member of the network isn't aware of every other member, and therefore a small malicious set of peer may be able to "capture" the routes of nodes that only know them or rely on them to boostrap into the network. The most sophisticated current research proposals are probably ShadowWalker by Mittal and Borisov (https://netfiles.uiuc.edu/mittal2/www/shadowwalker-ccs09.pd) and Torsk by McLachlan et al. (www-users.cs.umn.edu/~hopper/torsk-ccs.pdf). They are both certainly less vulnerable than MorphMix, which anyway is designed for high-latency communication.
Good thing I'll be at Pycon this year, definitely checking out this talk.
A lot of companies deal with traffic of this magnitude. UPS perform 12 billion transactions per day through their systems - DB2 on Sysplex'd mainframes. Finance companies are currently dealing with tens of thousands of messages per second with much more complex handling and forwarding rules than Twitter. And, of course, in terms of page reads, Google and Facebook leave them well behind.

Twitter has become impressive, but let's not overstate its achievements.
Exactly this. My web based usage of e-mail is down -- simply because I usually get my e-mail on my mobile phone. If anything, though, ease of access through mobile devices has increased my total usage of e-mail.
I hope you can get the experience of college, for personal development and learning beyond your scope of natural experience would take you.

But do the math. If you can't get a full-scholarship for school (tuition AND cost of living) you may put yourself behind financially. There are lot of people today in their early and mid-20s who are seriously questioning if their degree was worth it.

Old [school] people and large companies like that education bullet point. If you want flexibility in your career, you'll need some sort of bachelor's degree. But it doesn't matter when you get it!

If you're entrepreneurial enough (which you must be to judge a startup to be showing "a lot of potential") I think you'll never regret diving into a career doing what you love.
I think what is happening is that when someone else does the tickling, although we may know it's coming we don't know what exact details to expect. For example, will I tickle you lightly or firmly, and in what exact spot? Will I wriggle my fingers? How long will I persist? When we tickle ourselves not only do we know it's coming, but our brain can answer any of those questions, so it's really difficult to not anticipate any resulting sensation.

After playing with it a bit, I'm guessing it would be most useful for image galleries that contain a lot of irregularly sized images and you want to fit a lot of them on the screen. Or something like Google Image Search.
I may have missed this answer but how to they actually plan to survive as a company since they are giving the product away? Will you pay them for support or will they start charging for the solutions to the "longer term" problems they describe which salesforce solves today? I could be stupid or naive but why have otherwise smart people invested $9M into this?
I was in a similar position at the end of high school. I opted for college/internships, and I often regret that decision. While college has some unique benefits, especially in the ways of networking and unusual opportunities, you will find that work experience and actual ability matters far more in the software world.

Pick the job you think you'll like the most and go for it. The startup will likely provide amazing real world learning opportunities in software and business, so I would vote for that one. Given your skill you might also consider giving your own startup a go.

Do keep in mind that college will always be there, so if a job doesn't work out you can always head off to college. Also, here's a piece of advice I wish someone would have given me: when picking a college, do not settle for any reason. Find a place that will challenge your abilities and help you actually learn more about computer science. For financial reasons I opted for a state school instead of a big name school (where I had been accepted) and I've been frustrated and bored to tears ever since.
you don't hire a co founder because a co-founder shouldn't be considered just an employee, but an owner. I think you might want to fix your wording. You should present it more like looking to pitch my opportunity to other coders. Also maybe 104 lines of code is not a whole lot, thats like a good days worth of code for me. Maybe you can present it that you're looking for more technical help as well.
Are we looking at the same site? I see a clean, readable page. The navigation is kind of wonky, but the site is far from a disaster.
