Any differences between this and Vanilla (http://vanillaforums.com/), which has an abundance of community-created add-ons (http://vanillaforums.org/addon/browse/plugins) and the ability to really customize the forum to however you want it? I'm on a board that uses it, and we've been able to integrate inline private conversations into public threads, multi-user private conversations, the ability to draw a post instead of write one, etc.
Purely from a code standpoint, this is a pretty awesome repository to browse if you want to see how rails, redis, sidekiq, postgresql, pg's hstore, ember.js all tie up!

Gemfile gives a pretty good overview - https://github.com/discourse/core/blob/master/Gemfile

It doesn't appear to be responsive, is there a mobile version? The biggest problem i see with phpBB and the like is that they're a huge pain in the ass on any sort of mobile device, and then you get abominations like tapatalk filling the void. If somebody wanted to solve a problem with online discussion software, that's where I'd start.

Show HN: WTFlop - a 72 Hour Post Mortem (LeanPub/PDF Sales)
A Post Mortem of what started out as a “subscription site" and turned into a beta launch through LeanPub. Within 72 hours, we have 5/100 top sellers by all time money earned (http://bit.ly/NzgUSp). The content is well received and should allow us to shift into a paid subscription site.

($3115 sales - $320.42 fees) = $2794.58 Total Revenue in 72 Hours

Background:

The idea was to make a subscription-based site (similar to the other video training site models) for CardRunnersEV based PDF analyses. We ended up over scoping and under budgeting time for our initial site launch and things kept getting delayed (I’m sure HN empathizes).

We took the route of releasing "beta" content on LeanPub - easier for Danny and I to edit the markdown together in GDocs. Although 10% is steep for royalties long term in our position, LeanPub’s platform undoubtedly fit our beta purposes perfectly.

Launch:

* Bundled our 6 books into 3 bundles for people who specialize in different game types to buy at a discount:
* Heads Up (1 v 1) - 13% of revenue
* 6Max (6 Players around a table) - 16% of revenue
* All 6 Books (both HU + 6Max) - 64% of revenue
* Purchased a $200 / month coaching thread on twoplustwo.com
* Created Twitter account and tweeted our release/sample analysis links.

Future Plans:

1. Continue to promote beta content through twitter and sponsored articles
2. Get a blog up!
3. Stand-alone monthly subscription site w/ Stripe to accept payments

I am now all the more motivated to put in those late nights building out our stack w/ Stripe. Happy to answer any questions and would appreciate some critical feedback/thoughts on how to continue.

* Coaching Thread w/ Analysis sample: http://bit.ly/Ua971v
* Danny's Blog Post: http://bit.ly/VC3lRy
* "All 6" PDF Bundle: http://bit.ly/WsxiXX

Should You Hire A COO?
Thanks Jim! I loved having you as a teacher. One suggestion: can you make cheat sheets for all the code we write in each module? Would be nice to be able to recreate the app from scratch without watching all the videos.
I don't buy the argument that the new rules and equipment have made the game more dangerous. Back in the old days, 100 years ago or so, it wasn't uncommon for people to die on the field http://www.nytimes.com/2010/11/21/sports/football/21thorpe.h...

the 1910 rule changes were a reaction to a raft of horrifying deaths on the field. A total of 26 players died in 1909, including 10 at the college level. Thirteen in 1908. Eighteen in 1905.

Looks like you got downvoted, but I was confused as well. After reading the article, I conclude that Tesla could've used some of Tesla's ingenious strategies.
"That's really the point of living don't you think?"

Well, in my opinion, you shouldn't base your actions on what you can write on your resume... Do good things, regardless of how broadly it will be received. You can easily portray yourself as a saint but in reality do more harm than good, and get away with it. But why care the about how you will be perceived when you're gone? The time it takes to be forgotten doesn't have anything to do with how "good" you were.

If you did miracles for elderly people you might get forgotten a minute after your death. Does that mean that your actions doesn't count? Why would you even care to think about it?
By that argument, no director could have been said to have ever created a film. The cinematographer did the photography, the scriptwriter did the writing, the SFX department did the effects, etc.

Woz did a spectacular job with the Apple I design, but it wasn't the only kit available at the time. And even then he used off-the-shelf parts like the MOS 6502. Matter of fact, a kit that slightly predated the Apple I was the KIM-1, which also used the 6502. Difference was that the KIM-1's designer Chuck Peddle also designed the 6502 processor (yep, the one Wozniak used).

Steve Jobs kept going throughout the years, long after Wozniak stopped: the original Mac, the NeXT computer, NeXTSTEP, Mac OS X, iPod, iPhone, iPad, iOS, all of these were as much the creation of Steve Jobs as Yojimbo was Akira Kurosawa's creation or 2001: A Space Odyssey was Stanley Kubrick's film.
Rackspace has increased server costs twofold, and nobody has noticed.
I migrated to the NEXTGEN servers because of the benefits listed everywhere. I built a server and realized that our processes (which were cpu intensive) were taking twice the time they used to on Firstgen.

The response from their side was 'You get "occasional" CPU bursts in Firstgen & that is the reason.

I decided to benchmark the cpu performance & found out that I was right about it.

I contacted the customer care again with this tests:
http://pastebin.com/k0uefXMh

Joe concluded by saying ' The test results were because of occassional cpu bursts' , even when I mentioned that burst was accounted for.

The test results: http://pastebin.com/aArbwAq2

This time I wanted conclusive results proving the customer care wrong & placed 3 firstgen servers with a cronjob running every minute to benchmark to check for cpu burst. Following were the results :

All the results were consistent, proving me right. I went back to the customer care with this just to be terribly disappointed with their response. Here is the conversation : http://pastebin.com/cedtk1zL

Here is the benchmark script that ran every minute :

Increasing the price two folds is one thing & not informing customers about it is another. The latter is the one I am more disappointed in.
It's basically a combat sport. These days, the players know or ought to know that is the case. I feel bad for the guys who get hurt, but the ones playing at the college and professional level are being rewarded substantially for the risks they take.
A quote: "She says there is only a one percent possibility her findings are based on chance, and would like to see technology used to prevent these kinds of biased search results."

Translated into scientific jargon, this is a p < .01 value, or the statement that the result has a 1% probability that it could have arisen by chance and therefore mean nothing.

The problem with this class of p-factor is that it often offers false or dubious assurance that the result actually has meaning, for reasons given here:

Quote: "After 4 decades of severe criticism, the ritual of null hypothesis significance testing—mechanical dichotomous
decisions around a sacred .05 criterion—still persists."

One obvious criticism of this sort of "discovery" is that Google's search software tries to produce AdSense results based on what a person has searched for in the past -- therefore, even if an unscrupulous advertiser isn't deliberately targeting people with specific names, the unbiased core algorithms may well produce associations that may seem racist but are solely based on past search entries.

Another criticism of a study like this, more classical, is that, to achieve a 1% p-value, one need only test 100 random associations, each with a probability of 50%, pick the best one, and publish it. This is called "data mining" and by using it, a diligent worker can almost always come up with something:

You're right, sorry, I've been in a terribly bitter mood lately and I'm not proud of this comment

I hadn't read this post yet, it sure is alarming but I trust the ruby/rails community in the sense that it was always pretty fast to adopt, reject and take action on things and that it will keep this relative efficiency, specially against problems like these so at least this is something we can trust, I guess.

As for Django, go for it... it's just that this problems look really ugly in hindsight... 3 months ago it probably was, for most people, that Rails had most of good security stuff built right in, it can happen in another framework, in linux, or ubuntu next, that sort of thing...
In a most parts of India, day to day or intra day weather doesn't vary much. What you really need is what time of the day it will rain and if yes, how much. If this app can do that, then its great!
I agree that losing the hard equipment would make the game safer (take a look at rugby or Aussie rules: much safer similar sports), but I don't agree with the implication that the owners of the NFL ever had a nefarious plan to add equipment so that the game would become watchable (again, take a look at rugby or Aussie rules: very watchable similar sports).
I would venture to guess that most NFLers that have made a career out of taking head trauma would be much more in favor of furthering post NFL support (jobs, financial guidance, mental health support), and better helmet technology then watching their game go the way of Boxing.
I never really noticed how similar Go's function expressions are to JavaScript's before, but I'm now pretty certain they were one of the (subconscious) factors that got me into Go.

You still have to write the Ruby layer if you want to appear in the list. I think they should get rid of the Ruby file requirement.

The sniper is at his post near a military base. He sees a heavily loaded van approaching at high speed. The driver is ignoring the warning signs and shouts from the guards. The sniper shoots the diver. The truck is found to be loaded with explosives.

> MongoDB et all basically are built around the assumption that a schema is never worth the complexity. It's a bold claim that contradicts many decades worth of database research.

Unless MongoDB et al are saying "always use MongoDB et al and never an RDBMS", then I'm not sure how you arrived at the conclusion that "the schema is never worth the complexity."

If anything, the appropriate assumption is, "schemas aren't always worth the complexity." When they are, you use an RDBMS. When they aren't, you don't bother with the data integrity constraints.

On vaguely this subject, I had an idea that I mean to implement but so far haven't found time. The idea was for a captcha-type system that required the user to match bad arguments to whatever logical fallacy they fell into, eg. they'd have to match "If we tolerate homosexuality, how long before it becomes normal for people to marry their pets?" to "slippery slope fallacy".

I think requiring people to answer a few of these correctly might raise the standard of online discussion, both by keeping dumb people out and setting a tone of reasoned debate.

Please steal this idea, as I don't know when I'll find time to do it.
Great post, COO's can help scale an organization and optimize company processes. Should definitely compliment and help execute on the CEO's vision.
It's actually worse because you take what were 2 parallel operations (washing your hands and drying them) and make them two serial operations, not able to be run in parallel.
If you look on the discourse.org website, they are planning to eventually sell a hosted version (including custom domains). Discourse is taking VC funding, and that's their plan for making money.
But these things have already been researched for some time. More than being researched, they have been put into practice. And this has already shown us that they are relatively expensive and hard to scale, while hydrocarbons are cheap and scale well and are not subject to much in the way of political risk or NIMBYism. And this will continue to be so for decades at least.

Any promoter of renewable energy really has to be aware of this or they will not be able to target their interventions effectively.
Are you assuming that paper towels are more hygienic, or are you aware of studies? Personally, I doubt that the door handle out of the bathroom is any dirtier than other doorhandles in the building.

Is the center console software and/or hardware easily upgradable? A smartphone has a useable life of a couple years before either being unsupported (no more software updates) or replaced by a new model. An automobile is usually built to last much longer.

They probably won't license it out to other manufacturers, considering it's such a competitive advantage.
I think the general case is that it might have been innovative for one name, but the rest sound derivative, unoriginal, repetitive, derivative, unoriginal and repetitive. And many abuse the Lybian TLD.
I've been anti-todo list for a long time. Maybe I've been too harsh on them. But they have 2 major flaws for me:

-Putting the task on the todo list removes my desire to complete the task. One of my motivations is to get a project out of my head before I forget.

-My lists always get cluttered with stuff that sounds cool or fun, or stuff I feel obligated to do, but really don't want to do. Basically, it becomes a list of things I shouldn't waste my time with. But paring the list down is depressing because it forces me to admit I'll never do these things. Without the list I don't think about that.

I don't see how GTD would solve those problems.

If it's anything like StackOverflow then the focus will most likely be on nailing the gamification of moderation.

As far as building it for a real community goes; judging from their 'Buy it' page it seems that's exactly what they're planning to do next.
Agreed. Forums have two powers: 1) being hugely deep sources of information and 2) places where great conversations can persist.

Because of that, your forum thread topic should really have two views (sorts, if you will): Top replies and chronologically (we'll call that the status quo). Either I want to engage in a thread's conversation, or I want to know what the meatiest reply of the conversation is (and its context).

One keeps a thread alive, and one serves to make it useful in a future context. I'm surprised this is completely absent.

I'm no Sports-Ball expert, but two things you can do to make Football more enjoyable is lose the padding and lessen the constant pauses of the game (which frustrate me to no end, as a casual observer). These two reasons are why I find Rugby infinitely more enjoyable to watch.

Once upon a time people said that creating stuff in PHP was ridiculous as Perl in cgi-bin was way more supported.

As was mentioned, we have a hosted offering planned so people can set up a forum in a few clicks.

But besides that we actively want to work to make Ruby apps easier to install. Right now they're too hard and we're going to try and fix that.

At the very least we'll offer VM images and install scripts for various cloud hosts.
My answer has two parts:

1. Yes, by posting to the private forum Quora, you are certainly wasting your time and cheating yourself out of a larger audience. Choose a public forum, not one that requires visitors to sign up.

2. You're asking this at 27? I'm 67 and I don't need to ask this kind of question. I still have many goals and I'm likely to achieve them, but only if I don't waste precious time asking whether it's "too late".

In short, if your heart is beating, then it's not too late. At risk of quoting a tired old saying, today is the first day of the rest of your life.
I've always had trouble with the "no pads is a natural limiter to the amount/intensity of the hits" argument.

That said - those hard plastic helmets are weapons. They can hurt a player a lot more than a skull. Not sure what to do with that conclusion.

I love watching NFL football but its obviously a form of killing people slowly for our entertainment. I don't see how it can sustain unless we all look the other way on the brain injuries.

Community moderation based on increasing levels of trust worked well for StackOverflow and appears to be implemented for this as well. It's not unique to SO, but it works really well there and not (IMO) for Slashdot, so perhaps there is some difference that matters.

HN relies on a panel of hand-picked moderators, right? It works for HN, but perhaps not in other contexts.
Sure, I'm sure he thought of that, and I'm sure prices would change since there would be less money earned and therefore less money in circulation. This would also require a change in standard of living though. My point is simply that people cannot maintain the same standard of living and work less, even if the entire world cut back hours at the same time. Less goods would be produced, so with the same demand then prices for everything would rise, or standards of living would fall.
1. If you log in across various devices you'll end up with links to the last post you read in the topic. Unlike other forum software we don't consider all posts on a "page" viewed when the page downloads, only as they are scrolled into view.

I hate when people complain about football injuries. It's the risk and conscious choice that athletes take in order to make an enormous amount of money. If I were able to make millions of dollars for 8-10 years and risk having concussions and other physical problems later on in life, I would probably take it, especially if I came from an underprivileged background.

The real tragedy is that 80% of pro athletes go bankrupt because they don't know how to handle their own money. They made a life-changing amount of money, and they waste it all because they don't have proper guidance in terms of how to retain most of it. THIS is something the NFL needs to concentrate on, that these young kids don't blow all their money away because of immaturity and arrogance.
The word you're looking for is: "communicative." Seriously, for a relatively new company, they've done a great job of getting the word out about their stellar product.

I remember the first time I used threaded comments. I moved from the 1D world to the 2D world, and it felt right. I can't go back to 1D. I feel cramped.
That makes it basically "spectators pay players large amounts of money to injure themselves for our entertainment." I don't think that's the sign of a civilized society.
I keep a physical, paper notebook. I write todo lists, check things off as they get done.

When the list gets cluttered, I choose a blank page and write another list, copying things that didn't get done. If a thing is stale or no longer interesting, I don't copy it.

Now I don't have to keep everything in my head; I can keep ~20 things on paper and revisit the list every time I run out of things to do.
The infinite scrolling works in both directions (up and down). There's a "jump to last post" and "jump to first post" navigation aid to the right of the comment list. You can also start anywhere in the middle of a conversation if someone gives you the permalink to that comment.

No matter where in the conversation you begin, only a limited number of comments are preloaded into the page (before/after your current position), and the rest get loaded as you scroll down or up. If you're a search spider or other bot loading the canonical URL of the discussion, it's rendered in plain HTML and paged into multiple HTML pages if very long.
