The coderpath podcast (http://coderpath.com) will be interviewing Wayne and Dr. Nic later today (January 18th/2011 @ 4pm PST). If you would like the host of coderpath to ask them a question about the Rails Installer, add your questions here: http://titanpad.com/r8CWyBBA4T
Sorry for my rather brief thought. Here it is explained:

Napster changed the music industry forever and caused the music industry to (at least to some extent) change.

My thought is that proximity payments + API for banking system (ie: PayPal or Google equivalent) would shake things up for the banking industry.

In other words, if you could completely bypass the big banks - while they struggle to implement 10 year old payment system technology, not to mention high service fees - you'd end up with a system that is more convenient and manageable.

My point wasn't the file sharing aspect of Napster. It was about how Napster changed an industry.

Ask HN: Review our API - A single API to rule them all
We're in a very alpha stage of developing a "semantic" API, that has some powerful capabilities:

* Querying Linked-Data and other ontologies.

* Easy pipelining of multiple APIs.

* Math, logic, graph-traversal, IO, string manipulation, data mining primitives.

* A templating language for easy creation of mashups.

* NLP and semantic analysis of text and web pages.

We'd like to pick your brain about it: your general opinion, what do you think this can be most valuable for, what would be the barriers for using it.

CoreAnimation no, Flash no, Silverlight yes. Of course, even if there weren't a Silverlight branding badge, the Microsoft updater that starts every time you visit a page that uses it would remind you.
Very cool - I have yet to try it out, but if its as easy as the video suggests, this could be a boon for ruby/rails. I've made several attempts at introducing .NET developer friends to Ruby/Rails, but they've given up, due to frustration preparing the environment on their Windows boxes -- Hopefully this will help change that experience.
A definition of Google ad platform that does not include DoubleClick, YouTube, Gmail or AdSense Content Ads does not seem to me like a very complete definition.

Drug use is not legal. It constitutes an infraction of the law and if caught you may be forced to see a psychologist and/or rehab. Decriminalized means there are no criminal penalties. Other penalties may still apply.
You have a very narrow view of the world.

In reality, most developers will stick with HTML4+JS+CSS and use Flash if they want a canvas and timelines.

Most developers will wait for HTML6. No one needs an HTML5 'Movement'. That is ridiculous and shows ignorance in the work professionals do everyday in developing online apps and websites.

I assume you haven't read HTDP and that you don't know me apart from a single online comment, so I don't appreciate you telling me I lack self discipline.

Edit: I didn't downvote you.
The big assumption of this article is that Facebook has to rely on Google-style in-the-margin ads as its major revenue source. I believe Facebook has the potential to bring a new form of online ads, for example, a new interactive game-like campaign that virally spread across the friend network with those participants given incentives like Facebook credits.

It's rather limiting to think Facebook as an advertiser like Google. The real potential of Facebook is way beyond this. Facebook is not just connecting people to their friends. It is a middleman - a platform that connects customers to vendors, fans to artists, and gamers to game developers, and there could be much more than these. Think iOS as a platform that connects mobile users and app developers and how it has worked out - and would have worked out even it was a standalone company. Maybe someone will develop an Amway-style direct selling platform on Facebook. Maybe someone could develop a CRM and compete with salesforce.com for SMB. Or maybe a Priceline clone with social features would emerge. And good thing is Facebook does not need to do all these. It just need to inspire a developer community around it and evolve its platform to support new possibilities.

It's gold rush again, and like last time - it wasn't the gold miners that get rich; it was the people who sold the miners and other gold rush followers the tools and supplies they needed.

As far as easing pains for Windows development in a corporate environment, I don't see this as a silver bullet because of the poor support for mswin32 gems. BUT for Rails being taught in the classroom and other developers testing out Rails on the weekend - this could be a game changer.

XML Problem Design Solution
If you're repeating the exact same thing to a dozen different friends I'm going to assume that you (or they) are not engaged by the news -- which is what I call "life trivia."

Most of what I see on twitter is this trivia, "I refinished my floors," "I bought an iPad." Would you normally go out of your way to talk about this to anyone who didn't ask "What did you do this weekend?" Probably not, so why do you feel the need to broadcast it to the world via Twitter/Facebook/<Insert Lifeless Tech Here>?

Now take something you have a passion for. I personally am an avid homebrewer and love to talk about beer. I'll talk to a half dozen different friends about the latest batch of beer I made and have completely different conversations and get insights into what they like. I have friends that are huge into climbing, now I have no big interest in it myself, but their passion draws me into the conversations and over the past decade I've learned more about climbing than I ever would have if it were just some posts.

It takes an amazing writer to really evoke the emotions that most of our daily conversations have, and let's face it, the world isn't exactly filled with amazing writers.

I know a group of affiliate scam artists who were making great money with facebook ads two years ago. I still the ads they run, so I assume they're still making money.

There are plenty of people who drop $1k on Google ads and end up with nothing to show for it too. Just because it doesn't work for some people doesn't mean it doesn't work for others.
"What's that smell?" isn't a great start to a conversation about a neat new gadget that you just bought.

In Redis the use of the disk KV store is just one of our layers, live objects are encoded in a different way to allow the usual Redis data model, so memcachedb is not a replacement for this unfortunately.

Both BDB and innoDB are mature implementations of on disk KV stores, but unfortunately there are licensing issues in one case, and code not clean / bloated in another case preventing me from using this solutions.

Basically my reasoning is always: if there is a good supported library that I like, I can use this, otherwise it is probably more interesting to learn something new. When I'll write recovery tools, deal with bugs, and so forth, it is better to deal with your own code if there isn't something of readily available, sanely licensed, simple to undertand, and small enough.

I'm just learning ROR from an online tutorial (http://railstutorial.org/), and I wish I had this last week. For newbies like myself, I think installing the framework is sometimes such a big hurdle, it pushes one to give up early. Which is unfortunate, because I read the real challenges happen a few weeks in.

I had a weird issue where I had to reinstall xcode from the OS X DVD. Took a bit of Googling to figure that one out.
> "Most developers will wait for HTML6. No one needs an HTML5 'Movement'."

That doesn't make any sense. When IE6/7 and partially 8 become small enough, most competent developers will use HTML5 technologies in part of their work. Flash will always have its uses, and there will always be developers unwilling to migrate, but that faction is certainly not "most" in the long term.

Also, HTML6 isn't coming. The WHATWG has said as much.

So? With a 32 bit CPU and the capability to have more than a megabyte of memory, the Amiga was obviously capable of running Unix.

More interesting are the cheap 8 bit computers that could run Unix-likes. For instance, the 64K TRS-80 Color Computer could run OS-9, which is still in use today as an "embedded Unix".

> [...] there is a stepwise increase in difficulty if prices increase by $1, as long as the price was already at whatever the company’s magic number is for maximum to be put on a corporate credit card or signed for on a non-manager’s authority.

The idea of pricing in such a way as to require the least authority possible for a purchase is fascinating. I had never considered that monthly billing completely avoids administrative hurdles for otherwise equivalent costs billed up front. The real trick is figuring out what that threshold is...

I think this is key. Just like iirc led to im and online forums led to reddit/hacker news, facebook will lead to something else ... That is what interests me.
Can we give developers some incentive not to do this? Is there some better configuration of homes that will give them more money (higher margins), or can we change the culture so that people won't buy these houses? Or maybe regulation is the only way to prevent this?

Valve made a DLC for Left4Dead2, released for 360 and Mac/PC. Valve released for free on PC, but MSFT told them they must charge for it on 360, $7.99 (or thereabouts). In response, Valve had a sale on Mac/PC where all of L4D2 was $6.99, and then you get the new DLC for free.
Does atomz.com work? I tried it and it times out. Hadn't seen it, thanks for the tip!
One other consideration: I recall a 20/20 special years ago that showed how superficial society can be. They did a test where they had one 'unattractive' person on the side of the road who had no gas and needed help. Needless to say, they never received any help in comparison to the 'attractive' person who was put in the same situation.

The point that I'm making is that, maybe the reason why 'attractive' people may have a higher IQ, is that they are more likely to receive help from others based solely on their appearance.

Another point I would like to add: Maybe 'attractive' people feel the need to increase their intelligence, due to the stereotype that 'attractive' people don't need to have intelligence and can just rely upon their looks to get them through life.

You are absolutely right ... Facebook has broadened my social circle in ways that would have been impossible just 6 years ago ...

Sure I don't call all 600 people on my friends list every week or have deep profound conversations with them all the time, but now I know enough about so many people in so many different places. People I could never have met ordinarily.

And I met them through other friends so that gives us enough familiarity that I could go to a new city of a friend on facebook and think nothing about asking them to come have a beer with me or send them a note asking about things to do in their city or what not. It could become a stronger friendship or they could have no personality, but its the possibility of friendship that fascinates me.

We're still working out the kinks with new forms of online communication (twitter/blogging/facebook) etc, but once we do, I have no doubt that we will see that they are net positives for us as a species.

You want support? :

The world got along fine until facebook came out all of less than 10 years ago.

Since then lots of people have joined it and lots of people have left again, but arguably lots more have joined than have left.

Just like there is no obligation to join there is no obligation to leave and those that leave should not be made to feel guilty because "literally everyone else in your social circle is on Facebook, you're actually forcing them to go out of their way to interact with you, something that fits the definition to a T. Facebook is the preferred method of communication for most people, and if you're ignoring this and forcing people to conform, they'll resent it. "

If your social circle is defined by facebook then pity to you, there are many more established means of communicating with other people including but not limited to:

- personal contact in real life (visiting)
- the telephone
- letter writing
- email
- sign language
- the telegraph system
- telex
- flickr
- youtube
- fax
- smoke signals
- carrier pigeons
- various instant messaging systems
- sms
- twitter

And on and on, and quite a few of those didn't exist 30 years ago either.

Not using facebook does not force anybody 'out of their way' in order to communicate with you, the volume will drop a bit but those that want to communicate with you will always find a way at no great inconvenience to them, after all if the 'price' of facebook is low enough for you it is too high for me because I'm not an avid user of facebook.

That cuts both ways and the onus is not on the non-users to provide ease of access to the users of a certain medium.

Typically protocol negotiations will settle when a common medium has been found, and facebook is only one of many possibles.

Fortunately there is some freedom of choice left in this life and whether or not you choose to use a certain communications medium is one of the things we're still free to choose.

Just because something is a hype does not make it mandatory.
I think it highly unlikely that is what they're doing this for. More likely is this is the first step to many games featuring Steamworks on the PS3, creating a whole new market for them.

If Valve can fill what some see as a gap in the Playstation online experience, that would be quite impressive.
It's true that HTDP is a little slow, but Felleisen is a master of CS pedagogy, and it shows in the book. The "design recipe" system that the book presents is actually extremely helpful in designing software once internalized. HTDP and SICP are in my opinion rather complimentary--I worked through HTDP in a couple weeks and am still working through SICP when possible. I consider the background that HTDP has given me valuable, not only as a Scheme programmer, but as a programmer in general.
> The NYDN must take the blame here for giving me the URL that it did.

Nope, you get the blame for not editing the junk out of the URL; the filter here isn't especially smart, and merely adding a # to the end of a URL makes it think it's different. Know the limitations of the technology you use, and change your behaviors appropriately (or change the technology).

EDIT: I see that at least five people disagree with me. My reasoning is mostly related to the fact that, when I submit articles, I get the URLs from an RSS reader, which invariably means that there's a huge amount of junk at the end. So I edit it down to the smallest URL that works (sometimes stopping several times to make sure that the URL still works), because that's the polite thing to do (both to people opening the article and to the filter). Shifting the blame for not doing so to the entity provide you with the URL isn't, in my mind, the correct thing to do. Others may disagree with me.

This is the best ML book I've found to date. That said, a number of things about the second edition annoyed me. Chapter 4 (algorithms) had way too much meat in it.

Even if everyone is using new browsers, HTML5 is still not required to do anything that can't already be done using some other method.

They are promoting HTML5 over current industry standards, and so far it's been rocky. Example: Google actively promoting Flash support, but dropping video codecs. It's all promoting what is good for their business. Apple and Microsoft do the same.
