Like "agile", "lean startup" can mean pretty much... anything the person using the phrase wants it to mean.

With agile, sometimes the word is used to justify a rigid excess of ceremony, or as a firewall for lazy developers to hide behind to avoid being responsive to non-engineering members of the organization, or as an unrealistic attempt to turn software development into an assembly line of a bunch of jack-of-all-trades "cross-functional" team members ("specialists? we don't need no stinkin' specialists!"). But the core observation of agile is that writing huge planning documents and spending weeks perfecting PRDs and GANTT charts at the outset of an engineering project and then using these to derive project timelines and costs is inefficient, and that "delivery to QA" 3 months over an arbitrary schedule and 70% over an arbitrary budget is a classic failure mode for this approach to planning. Instead, a focus on building self-organizing, trusted teams who are delivering working software frequently and iteratively, and gathering customer feedback and adjusting "the plan" after each delivered increment of software can result in both happier developers AND happier customers.

Similarly, "lean startup" CAN be synonymous with "changing my mind about what business I'm in and 'pivoting' every 3 weeks", but really the core observation could be summarized as "build things people want", with all these new-fangled buzzword-y tools like customer development interviews, business model canvases and even "pivoting" as a means to this end. While the Ries book is useful, Steve Blank's The Startup Owner's Manual (http://www.amazon.com/The-Startup-Owners-Manual-Step-By-Step...) is phenomenal and the ideas there certainly "transfer very well outside the world of tech start-ups."

Take what works, leave what doesn't, ignore the hype and think critically.
Yeah; I converted the site to wordpress recently and just forgot to add caching. I've add W3 Total cache and things appear to be working better.
Do you have a source on that last point? It's very interesting and I don't think I've heard it before despite living in Canada. I'd love to get a deeper look at this.
Never tried it but that sounds like it could work great.

Looks around at all the diabetic, morbidly obese people.

Yep, working great.
Worst programming book? Easy, it's this one:

Learn OLE DB Development With Visual C++ 6.0

http://www.amazon.com/Learn-OLE-Development-With-Visual/dp/1...

I bought this back in like 2000-2001 or so, when I was doing a lot of C++ programming on Windows, and needed to do some work with ADO and OLEDB. Uuuugggghhh...

My review on Amazon from back then still pretty much reflects how I feel about this book:

Before buying this book, I was a little angry about the lack ofquality documentation on using OLE DB and ADO in C++. After buyingthis book, I am STILL angry about the lack of quality documentation on using OLE DB and ADO in C++, AND I'm angry about being out the bucks I spent on it. This book misses the mark on (what I took to be) it's intended audience, badly. Hardly a book for a beginner to learn the subject, it's just a rehash of reference material available elsewhere. Why, oh why, does Amazon not have a rating of 0 stars for these reviews? END
There is no evidence that this was anything more than simply bad writing. No comment from the screenwriter, nor Disney, but lots of quotes from opinionated bloggers.

The article is just bad journalism, and likely linux insider looking for page views.
Why do you say that? Is the knowledge that heroin is bad for an addict any motivation for them to quit? I hardly think so.

Considering that you can eliminate heroin from a person's usage and that you can't eliminate food it seems that the relapse rate for both is reasonably close.

Until obesity and eating psychology gets more study in this area, I don't think anything's going to happen to improve the health of the typical US citizen (or Canadian, eh?).
Good post on the exact problem I ran into when developing a machine learning algorithm to identify rule violations (basically fraud) based on self-reported descriptive text data. The few records that are "fraud" are precious from a training standpoint.

I found it helpful to start by over-representing the rare class and then slowly bring the balance back to the observed percentages.

The main reason for my over-representation of the rare class was that rare case was often not correctly identified (many false negatives) in the so-called "Gold Standard" training data. By over-representing the rare case, I was able to build a better training set while tuning your algorithm.

I'd be interested to hear if others flush out false positives in a similar/different manner (for the Skewed/Rare Class problems described by the article).
"your invention is so obvious that you shouldn't be incentivized for inventing it..."

Isn't selling iPhones enough of an incentive?
To what end? iTunes music has been DRM free since April 2009: http://news.bbc.co.uk/2/hi/technology/7813527.stm
IOS, Android adoption now twice as fast as 1990s Internet boom
I know it's not the main point of the article, but far too many articles these days seem to dwell on the number of jobs that can be supported by any given startup.

The most amazing thing, to me, about technology is how it enables such small groups of people to positively affect millions. Lamenting that this is possible without hiring thousands of people seems like a such a narrow and scared mindset to me. It completely ignores huge swaths of possibility and potential.
Call me crazy, but I think we're seeing Apple using the process to defend their inventions, which is exactly what the system was set up to do.

What exactly are they defending their "inventions" from? Other companies making competing products seems to be the biggest thing.

Patents aren't intended to ensure that consumers have rock-bottom prices on the latest consumer gadgets; they're intended to provide inventors with incentives to produce non-trivial inventions, by granting them temporary monopolies on their ideas.

Apple is an extremely successful business. What other incentives are necessary for companies like Apple to want to innovate?
#8 - Recognise bullshit when you hear it

Sums up most of the points in this article if you ask me.
I have to agree with you. I doubt they were very passionate or/and experience to tackle what they did.

To be fair, it was a little bit of fun for 3 college kids looking to raise $10k that blew out of proportion. I am sure they tried too hard to live up to the expectations.

Their new side looks quite interesting although I have my reservations about the name.
Its funny when you think about it because you never realize how important that site is for many people who aren't as savvy as the rest of you all.

Gotta remember that for every person who uses the web, there is someone who knows even less about it.

There is a niche for everyone. Literally.
My worst one was "Build Your Own Ajax Web Applications"

http://www.amazon.com/Build-Your-Own-Ajax-Applications/dp/09...

I got it at a used book store for $5. The second chapter was page after page of code to build an app to be used for the rest of the book. None of it was explained, and of course it didn't work for me and I didn't know if I'd made a typo or if it was just outdated. The book promised that the code would be available online, but the website was defunct. It ended up in the garbage at the end of the school year.
For those curious about the process: making the EPUB and Mobi files was excruciating. I'm currently working on a project that should make it much easier in the future. Stay tuned.
Is the slumping solar market temporary or a long-term trend?
Not really, but I doubt I'd mind if they were. You should take another pass on the MBAs at a Mac Store. Launch term, change some fonts, muck around a bit and see if it's acceptable. I was originally going to upgrade to the MBP retina, but changed my mind after using a 13" MBA for a few min.

iOS compiles could be snappier I guess, but everything else is fine. Its faster than my 2010 MBP anyways.
Office 2013 to offer one-off apps on demand
Especially given that the term of patent is 20 years. In the case of software, it's often the case that technology will have moved so far in 20 years that the invention will no longer be particularly useful.
This is really exciting stuff. At the moment it's awful, the performance is just terrible in both HTML5 and the Flash outputs, but it's got a tremendous future if it be can be pulled off.

To a large extent it's already been done by HaXe but they have pretty severe marketing issues that have limited adoption.
No, that will get them a phone that fails to infringe on these trivial patents. Surely Apple has more, and is filing for still more as we speak. As is every other player. The next victim may be Apple itself.

You can't win this game by avoiding infringement. It's never worked that way.
The future of unofficial Twitter clients might just be fully open-source code. Twitter can't stop every determined individual from creating their own application if the code is out there publicly. And with Twitter possibly cutting people off I wouldn't be surprised to see some clients become open source as they hit their cap. The question simply becomes how high the bar becomes for building your own personal Twitter application.

Actually, that would be a rather scary end-game for Twitter: completely losing control of their delivery platform.
In 2002, it was NOT obvious, and that is the point. Of course, we can look at something like PTZ or a bouncing edge and think, "It's so obvious, how else would you do this?" And Samsung or HTC or even Google could have figured it out and patented it - but they didn't. Apple did, and that is why we are here now.
The Visual C++ debugger can attach to a running process. I've used that feature to debug server code.
...they live together?
Thanks for putting this together. Was very educational working through each level (and felt great to capture the flag). Loved that it was spread out across node.js/python/ruby/php/javascript.

Were any unexpected security vulnerabilities found (or patched mid-game by you) in the overall infrastructure?

Not sure if this was intentionally left open-ended but for example in Level 6 I exploited a Ruby session/cookie bug to gain access to the target user, before realizing that the easier way was just a simpler JavaScript XSS vulnerability.
That is a good point - I'd like to actual before & after prices as well.

What I personally find most interesting is what this means about the difference between Android customers and iPhone customers in terms of price sensitivity. It may be strategic to price the same app differently across different platforms in some cases if possible.
Nah, I can understand that. I'm actually mildly hungry much of the time; part of tuning that feedback loop is identifying what level of "hungry" to consider, well, hungry.
You'd be surprised. I've been hanging around here for a few years and I have no idea who he is. Although a little voice in the back of my mind says he might be the Dropbox guy.
Thanks for the response - really interesting stuff. I'd love to take a look anything that you/your collaborators have published in this space if anything's out yet.
Aren't "users who will pay" the most desirable demographic for marketing to?
I tend to take this outlook. Almost all forms of calorie restriction works. When I personally point out that a calorie is not a calorie it has everything to do with satiation, motivation and the psychology of what makes people over-eat.

Limiting calories works. Keeping people doing that long enough to lose weight, and the rest of their lives to some degree (so no yo-you dieting) is the true challenge.
Yeah, GDB and Valgrind are heavily encouraged at the University of Michigan in both introductory and advanced classes. Talking to friends at other universities, it seems like most other places encourage it too.
Why would 3rd party Twitter client developers want to open-source their apps? Just to hurt Twitter at their own financial cost?

Thank you. I tried it and could not get OpenJDK installed. Also, it did not detect my wireless card. FOr now, I have postponed using it on my netbook. I will try it again when it has more driver support.
We got the 'food pyramid' which told everyone that eating loads of carbs is good for you and eating fat in any form is bad. It's gonna take decades to reverse this mistake.
I found the video on YouTube, but my question is how are they doing this? There's no way to access Mobile Safari from an app like this, is there?
You should use debugging not only to learn and fix bugs, but also to check your code actually does what you think it does.
>>but I have found the truth in this book!

Really? My comment pointed towards two books, and a follow up argument suggested Feinmans old well known article for kicks.

What exactly is the point you are trying to make? By contrast, your comment lacks any real substance other than accusing me inciting religious war and telling us about your burden having to worry that educated people turn science into magic.

Bullshit. Where are your articles? Please, point to the articles that show that a diet abundant in grain from carbohydrates is ok, let alone good for you.
One of the things you can do with BitTorrent clients is to have the client look for new torrents in specific locations (new episodes of a show for instance). The client with download the show to whatever location you specified, which could include a USB device if you so chose.

That seems pretty similar to me.
Imitation Is the Sincerest Form of Fundability
Everyone is an expert on diet.
I guess it depends on the college. My ECE intro to programming class taught gdb very early, basically right after we learned the basics of C. I thought it was pretty neat but it never really seemed like a huge advantage over printing, especially after I wrote a few logging macros.
Doesn't Apple have a patent on multitouch in general? Remember when the first few versions of Android did everything not to step on those patents? When and why did that change?
All files have revisions management in Google Drive. You can see this feature by doing: Right click on a file > Manage revisions...

Then it's up to the client using the Drive API to use the correct parameter when uploading a new change to create a new revision or overwrite the current revision.
If you invent a warp drive you will be awarded a patent over the implementation of it, that was never explained in ST for obvious reasons. So if you invent a real one, built to look exactly like the Star Trek one with an "interface" very similar to the one in the serie, and try to patent it's design and "interface", then Star Trek's warp drive will be prior art (for the design and interface, not the way it works).

See, not all patents are of the exact same kind, and there's a lot of things to patent about any thing. That's the problem... nowadays things that shouldn't be patented, like designs and user interfaces (even algorithms), are.

Also http://rstat.us, which I just found out about - not sure why it hasn't received more attention. It seems to be like a better identi.ca that can also automatically syndicate your Twitter posts. http://blog.steveklabnik.com/posts/2011-03-23-announcing-rst...

Edit: They're also planning to create a Twitter-compatible API, so a vendor like Tapbots could simply change the endpoint in their code and support rstat.us as well. https://github.com/hotsh/rstat.us/issues/562

It looks like homakov had a little fun with it (the guy who griefed github a bit half a year ago with their whitelisted attributes vulnerability and got the rails core team to put whitelisting on by default).
Apples pinch-to-zoom patent covers what we call pinch-to-zoom on a touchscreen. There is no other logical way to implement pinch to zoom on a touchscreen.

Therefore, they effectively have a patent on the feature pinch-to-zoom on smartphones.

It is also obvious. Had I been working on the iPhone and decided I wanted to implement the pinch-to-zoom feature from minority report, I would have done it exactly as described in Apple's patent--there is no other logical way to do it--using a touchscreen.

I can't use a different underlying algorithm, or even a different kind of touchscreen. If I implement pinch-to-zoom on a touchscreen I am violating their patent.
I think that's more academically interesting than it is practically useful. Some of the foods I eat may have calorie counts that are off by 20 or 30 percent? That's noise.

Being on an 1100 diet that you think is 1400 (or vice versa) doesn't matter that much. What matters is that it isn't 3500--something that can easily happen by accident if you don't pay attention.

I use managed hosting which sort of acts like this. They proactively watch my server and fix things when they go wrong (with server stuff, not my code).
In case you want to test a lander page keep in mind that
adwords considers also ad ctr and lander quality score
and that can be a reason for you not getting any clicks
or very expensive ones.

Tell me more about this. I have heard something like this before, but it didn't make sense to me for two reasons.

1) Until recently, traffic estimator worked, even if you
were not logged in, which, seemed to negate the idea of
them using site quality in their analysis.

2) Even when logged in, I don't ever actually link my ad-words account to any
specific site, and using traffic estimator or keyword
tool, I'm never given the opportunity to tell them which
site I'm buying ads for, or even which campaign I'm buying
ads for. I have multiple campaigns set up for different
sites. How would it know which campaign/site I'm
researching keywords for?
The Curious Use of Language in the Lance Armstrong Decision
GDB itself has a -tui option which gives you a nice "gui" style interface in the command line. As to why you would not use any sort of gui interface, I don't think the command line alone gives you any advantage as far as I know.
> The problem is that solutions like this aren't realistic. If Twitter's going to show ads and other content like cards in their stream, advertisers have to have confidence that the content and presentation will be preserved. The only way to truly do this effectively is to control how your product is presented in all cases.

Thank you. It amazes me how people miss this. Look at it from the perspective of Twitter's customers (advertisers). Would you buy an ad without seeing exactly what it looks like, or without knowing with certainty that what they show you is what winds up in front of the users eyeballs? Having worked in advertising, companies pay attention to every last detail of an ad piece. This is the exact reason why Twitter has gone this way. That have to sell themselves to companies as trustworthy partner.
It's a great point, and well articulated.

In the case of the example in the post (fraud), the credit card industry has actually termed the false positive rate the "insult rate" (because the customer feels insulted in the store that their charge has been declined), which certainly gives you an idea of how they feel about false positives.

Absolutely. I never understood the people drooling over the Samsung Galaxy <x> devices, they all look pretty ugly to me. I have an HTC One S which I consider to be marginally better, but the dream is a Nokia Lumia... running Android.
There were a few unintentional vulnerabilities in the levels. Only one actually made the levels significantly easy enough that it was worth patching -- namely, the session cookie bug you reference (it actually affected three levels). There was also a bug in the CTF architecture where you could set your user's URL to a javascript: URL. But to my knowledge no one has found vulnerabilities in the rest of the infrastructure :).

You would't even need to open source it, just have a field to enter your developer key.
