I built this because I wanted to know if there are any other Entrepreneurs near my place in Singapore.

I never used OAuth before and I never leveraged any well known API before (like Facebook or Twitter). Usually I use Python/Django for all my web projects but I felt that a full blown Django stack would be overkill here. So I googled for "python mini web framework" and eventually found "web.py".

With the help of the tutorial I got a prototype running quickly (3 hours or so). Another 10 hours have been consumed by the creation of my hourly database-updater (a simple Python script). Another 5 hours were killed by the creation of the client side JavaScript and all those pitfalls when it comes to asynchronous programming, callbacks and closures. I guess around 2 hours went into HTML/CSS issues.

Ah one more thing: I would probably have given up half way without this neat python-jammer-oauth project on github: https://github.com/lemonad/python-yammer-oauth

You point to recent Google failures, but isn't their culture of allowing (even high profile) failures not only to get implemented, but then to get shut down part of why Google's successful? Which (the culture of allowing failure) seems like an engineering approach, and not a managerial (which to me has always struck me as fear-of-failure/CYA) one.
"Anticipating potential astronaut transport needs, Falcon Heavy is also designed to meet NASA human rating standards. Falcon Heavy is designed to higher structural safety margins of 40% above flight loads, rather than the 25% level of other rockets, and triple redundant avionics. Despite being designed to higher structural margins than other rockets, the Falcon Heavy side booster stages have a mass ratio (full vs. empty) above 30, better than any launcher in history. By comparison, the Delta IV side boosters have a mass ratio of about 10."

I don't want to sound cold, but it depends on your SO and the startup. If your SO is someone you can't live without, then your decision is clear. If your startup is going to make your life so much better, and it's your ultimate passion, but your SO can't accept that, it's time to move on (from the relationship).
Nice summary :)
I think your conclusion of a dishonest, delusional and controlling person may be a little off, but I see what you're saying. When we first started dating, I wasn't like this. Sure, I still hacked, worked hard and built things. But I admit that I did change and started working more and being serious about the startup lifestyle. I should also mention that we started dating when we were still in college.

Well said. Not just diminishing returns either, but scrolling past a comment branch full of "It's just a flesh wound!" or some other oblique reference is irritating.
Yeah, as a long time EngineYard AppCloud customer, I have to defend them a bit here.

1. The platform has evolved in a nice, iterative way with no interruptions to my service.

2. Even without a support plan, they have some of the best people in the world answering questions in the forums.

3. I'm happy to see competition in this space, and I don't begrudge anyone from pointing out their relative advantages over their competitors.
I like what you said, and it mirrors my experience. It comes down to what your priorities are. In my case it's family, work, then other stuff. It's a lie to believe that you can have/do it all, but it's generally true that you can have/do the things that are really important to you. I don't ride motorcycles, fly RC airplanes, or play guitar much anymore, but I'm okay with that because they were lesser priorities than the top two.
No, it's still very early. My intention was not to submit it until we had a prototype to show off, however it was submitted as a comment earlier and received a lot of good responses, so I figured it couldn't hurt.

Hopefully we'll have some demo photos and videos up over the next couple of months.

Backbone Tutorials - What is a model?
Actually, that presentation comes from an Areva engineer, not from Stanford. Here's the original (internal?) version:

http://energyfromthorium.com/2011/03/30/areva-fd-presentatio...

Some interesting intrigue here. Apparently the version you linked redacts the author's name from the second page (Matthias Braun), and removes the signature with his name and the Areva logo from every following page.

There's a NYT article that confirms this much:

Stanford, where Dr. Hanson is a visiting scholar, posted the slides online after the March presentation. At that time, each of the roughly 30 slides was marked with the Areva symbol or name, and each also gave the name of their author, Matthias Braun.

The posted document was later changed to remove all references to Areva, and Dr. Braun and Areva did not reply to questions about what simulation code or codes the company may have used to arrive at its analysis of the Fukushima disaster.

“We cannot comment on that,” Jarret Adams, a spokesman for Areva, said of the slide presentation. The reason, he added, was “because it was not an officially released document.”

Ah very cool. Tangentially related: I've been helping a client get some affiliate marketing set up, and the email-based affiliates require CAN-SPAM compliance. Basically, this requires a generic unsubscribe link where people can put in their email address to be added to a "suppression file" blacklist, which the affiliates can then download. It's intended to act as a shared blacklist when you're working with multiple affiliates, but I'm wondering what's to stop someone from just harvesting suppression files?

This looks pretty neat; I am unclear about one thing tho:
Reading the TNW article, I got the impression that OwnLocal would help local papers with their web presence, social media blogging, all that, and I assumed a news publishing platform (I think I was way off here) as well as ad sales and generating revenue on the web.

When I visited the site, I saw only ad-related products. Am I missing something, or did I misread that article (perhaps it is just an ad company). I salute your effort to assist local papers either way, they can use all the help they can get, but I wonder: is this a newspaper publishing platform, or mainly an ad platform?

Can't watch the video right away, but I'll just say that every time I read the ZeroMQ guide (http://zguide.zeromq.org/page:all) I am frustrated by the lack of any clear technical explanation of ZeroMQ's basic architecture.

Today I gave it another shot, and after half an hour of trying to glean technical detail and skipping any parts that read like a like a comic book ("zap-pow-kaboom satori paradigm-shift moment"), I think I've learned the following:

* ZMQ works by spawning a background thread that runs a
poll() (or equivalent)-based async I/O loop. This thread
is created when you create a ZMQ "context."

* On top of a context you can create a ZMQ "socket", which
may map to N underlying UNIX sockets (or a comparable
transport), and which will transparently queue data to slow
or unavailable receivers.

* Over a socket you can send or receive "messages", which
are length-delimited strings which are always delivered
in full with the original length. Send/receive can be
either blocking or non-blocking.

* Contexts can be shared across threads, but sockets are
not thread-safe. Communication between application threads
and the ZMQ I/O thread is via a lock-free queue.

The main features seem to be topology-agnostic programming (since you don't have to know what a socket is connected to to send/receive over it) and transparent queuing. In my opinion transparent queues can be problematic because they transparently use up memory that can be hard to account for. Topology-agnostic programming certainly seems interesting, but in my experience of distributed systems programming I never seem to need or want complex messaging topologies. I guess I don't really get what all the hype is about. Maybe I should watch the video.
Did you read the entire article?

Nobody knows how many natural short sleepers are out there. "There aren't nearly as many as there are people who think they're short sleepers," says Daniel J. Buysse, a psychiatrist at the University of Pittsburgh Medical Center and a past president of the American Academy of Sleep Medicine, a professional group.

Out of every 100 people who believe they only need five or six hours of sleep a night, only about five people really do, Dr. Buysse says. The rest end up chronically sleep deprived, part of the one-third of U.S. adults who get less than the recommended seven hours of sleep per night, according to a report last month by the Centers for Disease Control and Prevention.
That is probably true globally.
It's part of their "local" push in order to bring back the tons of small business customers that tried adwords once, didn't know what they were doing and got burned.

Interesting to see how this goes. Adwords is so competitive that it's almost too expensive for small guys to hire big agencies & too time consuming to learn for small businesses to figure out themselves....

I just took a look at this as I am a BOA member. Most of the offers they have are 1%-5% cashback. Essentially we would be looking to get exclusive discounts for our members that are much better than this. 5% cashback on a $120/night hotel stay is only $6, compared to a 20% discount we may be able to get you at the same hotel which would save you $24.

I just want to be clear that this was a $5 experiment that I intended to share, post, and blog about for purposes of learning about Facebook advertising.

I'm not claiming fair use, simply saying that, for the amount of money involved, I was happy with doing as much diligence as I could and then be willing to remove the ad if it was in error. And as far as I know, copyright had nothing to do with the ad being rejected. My theory as expressed in the article was that it was the effectiveness of the picture, not copyright, that caused the problem. After all, I got the image from reading an article about posting ads on Facebook. In that article it showed several FB ads with this image on it. I thought that if the article was about posting ads, and this image was included, then there was some implied warranty. Like I said, I'm not trying to make excuses, simply explain. At the time I wasn't too terribly interested in the providence of the image, simply learning how all the pieces come together for an intended effect. Having said that, I'm perfectly happy with using the image in a blog article about the image itself -- if that's not fair use I don't know what is.

As of right this minute, none of us know who this person is or what kinds of protections are involved. Since I have received multiple claims to know who she is, and since they are all different people, I believe it is reasonable to expect that the image is of insufficient resolution as to be identifying of any one particular person. So -- unless something changes -- we can never really know, at least in the fashion you indicate. There is a huge amount of material on the web that falls into this area, and a lot of murky edge cases. For instance, FB thinks it is okay to post the same image on my website's fan page, even though FB runs ads on those pages? FB can use the image for it's commercial purposes but I can't use it for mine? All those "memeish of images" you refer to -- much of it on FB feeds -- isn't an issue for FB for purposes of placing their own ads?

There seems to be some serious inconsistencies here. I'm probably in error, so I apologize to whomever I might have offended. But I am not happy at all that I understand the current state of things to the degree necessary. I don't think anybody does -- I think at the end of the day it's a personal evaluation of risk. I'm also not happy that I wouldn't inadvertently do the same thing again -- that I'm not, in fact, doing it right now, by sharing funny pictures I find with my friends on FB.

That's really screwed up.

I could argue on and on about this -- but I have no desire to do so, or to use the image in an ad. I strongly feel that some folks would have taken that risk, and that it is a reasonable decision to make, and it bothers me that so many people would let their judgment of what's too much risk for them be the rule for everybody else.

Well that gives a new perspective on stealthmode startup. I don't hide projects, but I do secretly check my phone and answer emails when I'm with her. I know it upsets her when I get my phone out when we're together, so I'll save quick emails when I "go to the bathroom."
Sorry, this was not my intention to mean so: I used "optimization" for lack of finding the correct word regarding the role of the PCRE setting. My point was that the quickness of the initial results was fishy enough to doubt of the correctness of those results (and hence diving into regex engine probing), even before finding actual false positives.

- MUMPS, COMPASS, ChucK, MATLAB, KRYPTON, Inform, Arduino, Oracle, R: I assume people were actually searching for something different.

This is especially true if the government requires zero radioactive material to appear in the sea water. So any accidental discharge is going to have some scary multiplier over the near zero levels.

The media also seem to also like the Becquerel scale along with cm³ instead of m³ to make the numbers extra scary.

I found an interesting article that describes some safe levels and also the calculation of Becquerel to Sieverts.

I started using ZeroMQ at work a few weeks ago after reading the guide.

The part that I like about ZeroMQ is that it's a simplifying abstraction, e.g. it's a fairly simple wrapper about sockets that makes life easier for me. I guess it's mostly like a library of patterns for socket usage, so it makes a request-response loop and pub-sub scenarios really easy to implement. The other thing that's great is that it's pretty much programming language agnostic, meaning that C++ code and Python code look fairly similar and can trivially be used together.

As for the transparent queueing, there are simple options to control the size of the queue; it's even possible to spool the queue to disk as soon as the memory limit is reached (see setsockopt docs and look for HWM, for high water mark).
I'm not sure that counts as an explanation :) For details you could read his published papers on the subject:

Clealy not the norm. But it's nice to see some hard numbers. I think if you're in the top 25 apps in any particular category you're probably doing pretty well (exception being some of the lesser visited categories).

That said, I believe it's incredibly difficult to get yourself into a position where you're really making a solid income from your app on the App Store. With so many apps vying for attention you truly need to make your app unique and extremely solid or you risk being forgotten or never seen.

I think the best way to gain momentum is to be the type of app that can be advertised via word of mouth. I don't think I've ever seen Camera+ advertised anywhere (my memory isn't that great so maybe I have seen it) but the word of mouth in various forum posts is incredible. At least at the start this can really help. Once you have some traction and in the top 25 you get the benefit of some Apple advertising via the featured app section (hopefully) and sales take off a bit more for you.

I really think Android will never have this type of sales volume for paid apps. It is pretty incredible what Apple has done with the App Store, and what developers have done with it.
