Titanium Mobile: OpenGL ES Docs

September 1, 2011

OpenGL IOS Module (Docs)


Ti.OpenGL extends the Ti.View class with a Titanium view that responds to Open GL API commands and renders the resulting graphics. Ti.OpenGL views provide Javascript wrappers for almost all of the ES 1.1 and ES 2.0 API. In some cases, the Ti.OpenGL versions have been modified to accommodate the differences between Javascript and lower-level codes like Objective C and C++. Read the rest of this entry »

Heilmeier’s Catechism

March 23, 2011

Just a reminder to the startup community to think about Heilmeier’s catechism when creating products or solutions.

George H. Heilmeier is credited for asking a set of very basic questions that anyone proposing a research project or product development effort should be able to answer. Read the rest of this entry »

D + B School

March 22, 2011

“Design + Business” is a school of thought that hits at the heart of an identity crisis that I have personally struggled with: should I design or should I study finance/revenue and build a business. I find my self struggling to balance between the two as I work on startups, solve problems, build apps or productize ideas.  Form vs function is often conflicting in my mind… Read the rest of this entry »

At Fred’s Ranch

March 17, 2011

Panorama of the stables and corral. Fred is getting a lesson.

In late 2010 I had the pleasure of starting a company with a friend in California.  During my time there, I stayed at Fred’s ranch while we both worked on a new startup called Needly.  Fred’s ranch is a beautiful backdrop to the countless hours we invested in brainstorming, whiteboarding and problem solving.   Read the rest of this entry »

How to upgrade Debian Lenny to Squeeze

June 19, 2010

I use Slicehost and typically provision Debian Lenny.  But, after trying to install Beanstalkd, I found out that Lenny doesn’t support the required package, libevent-dev (1.4+).  Time to upgrade my slice to Squeeze.

Here’s how to do it:

Edit sources.list

sudo nano /etc/apt/sources.list

Change any word Lenny to Squeeze, (or from stable to testing) and save it.  Backup your original file, just to be safe

Updating and upgrading

sudo aptitude update

sudo aptitude install apt dpkg aptitude

sudo aptitude full-upgrade

Thats it.  You will be prompted with a few screens to authorize the upgrading or removal of certain packages and/or dependencies.  Take note of which packages will be altered before you proceed.

After this, you should be on running Debian Squeeze. Note: It is better to use Squeeze instead of testing.

This web site describes how to install and get started with the Mobiliti framework. It covers both mobile and server-side programming, and it focuses on example code and use cases.  It does not provide a complete reference to all of the APIs.  Please refer to the Javadocs for this information.  The site only covers the core framework, for more information on Mobiliti check out the Mobiltect web site.

About this site

This documentation is intended for developers who want to learn the basics of using the Mobiliti framework to develop mobile apps running on the Android platform.  The instructions will help you get started and show you how to use Mobiliti to build apps; the information does not assume (or require) an in-depth knowledge of Android, but it does require basic knowledge of Java and XML.

Throughout this site, sample code is provided to illustrate programming with Mobiliti.  Notice that the code in some cases may be incomplete and thus would not compile.  For the sake of brevity, only those code snippets relevant to illustrate some point may be shown.  However, sufficient comments and variable declarations will be provided to make the code illustrations self-explanatory.

Disruption: eBooks, The End of Windowing and The Agency Model

March 3, 2010

…In effect, Macmillan is trying to do exactly the same thing that many other media companies are desperate to do — from newspapers to music labels to movie companies — which is to replicate the pricing model of an analog, real-world business in digital form.

In other words, (windowing) tries to artificially reproduce the kind of scarcity (and thus pricing power) it used to have in one medium in a medium that doesn’t even know what scarcity is.

Sooner or later, that attempt will fail (among other things, iTunes appears to show that flexible pricing actually leads to lower sales).

For now, Macmillan and other publishers have managed to convince Amazon and Apple to accept the new agency model, but those sandbags aren’t going to last for long.

My take: “Macmillan, like most publishers, is attempting to protect their existing printed business long enough to readjust their production, sales and distribution model to digital media, rather than print media. Until then, their pricing model for eBooks and print media will be closely related and will walk in tandem towards a new model; at least in theory.”

“What we are seeing is a change in the business model of content distribution. There are simply more efficient and effective ways to subsidize the cost of transporting information.”

“Content is a service and a book is the conduit and container.”

Syndication: O’Reilly Digital Distribution Debuts (ODD) at TOC

February 24, 2010

Looking to turn its e-publishing expertise into a new business, O’Reilly Media is launching O’Reilly Digital Distribution, a new division offering publishers a complete e-book publishing service. Starting with text conversion, O’Reilly Digital Distribution can output files in any format for any device or e-reader and market and distribute the e-titles though an extensive and growing network of e-book retail channels.

In an interview conducted at O’Reilly’s annual Tools of Change conference in Manhattan, Laura Baldwin, chief operating officer of O’Reilly Media, said the new service will offer free conversion as part of a comprehensive program that will secure and store a publisher’s digital files and market and distribute them into 24 digital e-book retail channels (with 40 more under development) and in every format. ODD can turnout e-books for any format–from Kindle to iPhone to Stanza and Android readers like Aldiko. Publishers pay a fee of 25% of sales–no fees, she emphasized, until the e-books are in the sales channels. “We’ve automated the process of digital title conversion and production and for us this is all about sales and marketing,” Baldwin said. “It’s about getting e-books into the retail channels and there are more channels coming online all the time.”

Baldwin said the service grew out taking over the distribution of Microsoft titles last year. “We won the bid because of our sophisticated digital infrastructure. It took us seven weeks to go live with 200 Microsoft titles and make them available as e-books and apps.” A longtime champion of the e-book category, O’Reilly has seen its own e-book sales rise steadily and the publisher has been aggressive in offering e-books in all formats as well as bundling e-books with print. Andrew Savikas, O’Reilly’s v-p of digital initiatives, has said that O’Reilly’s Safari Books Online, a subscription service that gives it client access to library of digital titles, is its second largest sales channel.

The new division will be directed by O’Reilly Digital Distribution general manager Pascal Honscher and Baldwin said the company would be hiring new workers as well as promoting from within.

Baldwin said they were marketing the service to all kinds of publishers, not just technical houses. “We’re looking beyond technology books to poetry and fiction,” and she said the services and pricing can be customized to what a publisher needs. “If a publisher only needs conversion or only wants marketing and distribution support, we’ll work with them to come up with a different price.”

Baldwin compared the new service to the annual TOC conference: “The TOC is designed to help publishers and this service has evolved out of that. We know technology is driving the publishing business now, but people shouldn’t have to deal with technology issues. We want to take the technological confusion and ambiguity away and help publisher get their books to readers.”
