The Warnock Algorithm or, rather, the Warnock Influence

Posted by & filed under Uncategorized.

John Warnock (co-founder of Adobe) is not just known for being the mind behind Adobe, PostScript, and Acrobat. Prior to Adobe, he worked for Xerox PARC and was one of the foremost scientists in leading the effort for JaM (“J” being John; “M” being Martin Newell, famous for the Utah Teapot), the precursor to PostScript. We all know the Xerox PARC story. This is not about Xerox. Read John’s first document on Acrobat, codenamed Camelot. Even before Xerox, John Warnock was already famous. He was known for the Warnock Algorithm, a hidden surface removal algorithm published in most computer science graphics books. Imagine having an algorithm named after you. That’s impressive. He comes from an elite group of distinguished graphics pioneers that studied at the University of Utah.


The importance of opening our offices to you

Posted by & filed under Uncategorized.

A few days ago, Jonathan Beebe of Beebe Games (makers of Tilt Monster, Cavern Drake, and a few others) dropped by our offices and spent the day with us. A day later, Cesar and Edgar Miranda (the GDC Startup camp winners) stopped by the offices to hang out; and this past Friday, Angelo and Tobiah from Yobonja (makers of Blast Monkeys, our February App of the Month winner) also stopped by the offices to say hi and chat. They all tweeted that they were here, took some photos around the offices and with us, and we all later went out to dinner afterwards with our guests. I received an e-mail asking me if we ever worked, and why we let outsiders into our offices. At first,


But wait, there’s more!

Robert Nay talks Corona SDK and Bubble Ball, before 3 million downloads

Posted by & filed under Uncategorized.

Last week, when we chose Bubble Ball as our App of the Week, we talked to 14-year-old creator Robert Nay and his mom Kari of Nay Games about their experiences with building the game and using Corona SDK. However, we decided to keep the interview on ice to let Robert bask in other, bigger spotlights. Now, we’re finally sharing our chat with the Nays, from before Bubble Ball went on to 3 million downloads (so far!). Kari, as part of Team Nay, what was your contribution to Bubble Ball? I got to do the grownup stuff like read all the license agreements.  I also designed many of the game levels.  I drew them on paper and Robert did the programming to turn them into the


Bubble Ball (and Corona SDK) in the news!

Posted by & filed under Uncategorized.

Bubble Ball had quite a run in the press over the long weekend. As an added bonus, Corona SDK also received a lot of media attention and subsequent downloads, which benefits you (our users) the most as the Corona community and mindshare expands! At the moment, Bubble Ball has been downloaded over 3 million times from the App Store. I’m assuming you’ve got your copy already, right? Oh, and in case you missed any of the headlines: Good Morning America, ABC News But wait, there’s more…


Sleeping Bird's Julien Paté talks creating his first mobile game ever!

Posted by & filed under Uncategorized.

This past week, we awarded our App of the Week title to Julien Paté for his beautiful tap-challenge game Sleeping Bird. Shortly after deciding that it should be the App of the Week, we found out that it was Julien’s first mobile game ever! So, we decided to ask the France-based mobile dev rookie about how he got so good at mobile development in such a short period of time. Before Corona, what other experience in development and design did you have? I’ve worked in multimedia for the past three years, and have skills in graphic design (Photoshop and Illustrator), web development (PHP, Javascript, ActionScript 3, and CSS), and some skills in video editing (After Effects and Final Cut). I also have designed many websites and

Be sure to “Like” us on Facebook and follow us on Twitter to stay in the loop of things — sometimes, we even post exclusive promos on our TweetBook without necessarily announcing them here.


The Corona ecosystem is coming to life!

Last week, we passed a tremendous milestone: Corona SDK topped 15,000 downloads! With a growing community comes a growing mindshare that mutually benefits everyone involved. A great example of this is the increasing number of third-party tools that now are being created by our users for the rest of the Corona community. Examples of these include the eye-popping Particle Candy effects engine and the new, very handy Corona Project Manager for organizing your assets. To further kick-start our burgeoning Corona ecosystem, you can get both tools for 50% off until the New Year.  Simply head on over to our new Third-Party Tools page to get the coupon codes now!

Carlos' Ten Commandments for Entrepreneurs

Posted by & filed under Uncategorized.

For a number of years I have been invited to give a series of talks at Florida International University’s School of Computing and Information Sciences and at the University of Miami’s College of Engineering. Both schools asked me to elaborate on my experiences as a software engineer at a Fortune 500 company and about what it’s like to start a company in Silicon Valley. This past Tuesday, (November 2nd) I was invited to FIU to chat about what I thought was going to be about the challenges of going mobile and how Ansca — with its Corona SDK — solved the problem of platform fragmentation with iOS and Android devices. With FIU being far removed from Silicon Valley, I figured the students would benefit not
