Unity is a multi-platform game engine that is capable of producing games for consoles, PCs, touch devices, and the web. In particular, the engine has been used to create some of the most popular mobile games in recent years, such as Rovio’s Bad Piggies.

David Helgason, CEO of Unity, announced in a blog post on Tuesday that the company has stopped selling Flash development licenses.

Unity will continue to support its existing Flash customers “throughout the 4.x cycle.” Bug fixes will be made in future Unity 4.x iterations, but further development for the Unity engine on the platform has ceased.

The decision was made, Helgason stated, because of Adobe. Helgason called recent versions of Flash unstable and stated that, “We don’t see Adobe being firmly committed to the future development of Flash.” He also pointed out that Adobe has cancelled the Flash Player Next project.

Instead of Flash, Unity will be concentrating its development on its own Unity Web Player. Helgason stated that the Unity Web Player is installed on over 200 million computers and is used by one-third of all “Facebook gamers.”

“We look forward to gathering at WWDC 2013 with the incredible community of iOS and OS X developers,” said Apple’s SVP of Worldwide Marketing Philip Schiller. “Our developers have had the most prolific and profitable year ever, and we’re excited to show them the latest advances in software technologies and developer tools to help them create innovative new apps. We can’t wait to get new versions of iOS and OS X into their hands at WWDC.”

WWDC will feature over 100 technical sessions from over 1,000 Apple engineers.

Here’s what’s on the schedule for the event so far:

• More than 100 technical sessions presented by Apple engineers on a wide range of topics for developing, deploying and integrating the latest iOS and OS X technologies;
• more than 1,000 Apple engineers supporting over 100 hands-on labs and events to provide developers with code-level assistance, insight into optimal development techniques and guidance on how they can make the most of iOS and OS X technologies in their apps;
• the latest innovations, features and capabilities of iOS and OS X, and how to enhance an app’s functionality, performance, quality and design;
• the opportunity to connect with thousands of fellow iOS and OS X developers from around the world—last year more than 60 countries were represented;
• engaging and inspirational lunchtime sessions with leading minds and influencers from the worlds of technology, science and entertainment; and
• Apple Design Awards which recognize iPhone®, iPad® and Mac apps that demonstrate technical excellence, innovation and outstanding design.

At last year’s WWDC, Apple pulled the lid off OS X Mountain Lion and iOS 6.

According to a report from Gamasutra, Apple is sending out notices to some app developers that let them know that their games or apps with the word “memory” in the title have to be changed or they have to go.

Apparently, Apple is sending these requests at the behest of a German game maker called Ravensburger, who claims that they hold the trademark on the word “memory” in many European countries (and some in other parts of the world).

Those countries include: Armenia, Austria, Bosnia and Herzegovina, Belarus, Belgium, Brazil, Croatia, Czech Republic, Denmark, Egypt, Equador, Estonia, Finland, France, Georgia, Germany, Greece, Hungary, India, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Macedonia, Montenegro, Netherlands, Norway, Peru, Poland, Portugal, Russian Federation, Serbia, Slovakia, Slovenia, South Korea, Spain, Switzerland, Turkey, Ukraine and Venezuela.

Of course, their trademark (granted it’s legit) doesn’t pull any weight in the United States. But any app in the App Store that is available to an international audience would be affected by it.

And there are plenty of apps that fit the bill. If you search the App Store for apps containing the word “memory,” you’ll find that it’s a fairly popular term within the ecosystem. I was able to spot over 50 without really diving too deep into it.

Ravensburger offers a card game simply called “Memory,” which is similar to the paired match game that we’re all familiar with. They also offer branded versions of the game included Toy Story Memory, Winnie the Pooh Memory, and Hello Kitty Memory.

“Suppose you want to publish an app on the Chrome Web Store and have it associated with your company’s existing site, but you don’t have the ability to use any of the current verification methods e.g. you’re not allowed to upload a verification file to the root directory,” says Google developer advocate Joe Marini. “The site verification service option in the edit page for each item listed in your Chrome Web Store developer dashboard allows you to request association of your app with your organization’s site.”

“When you choose an existing site from the drop-down menu or click ‘Add a new site’, the current registered owner for the site will receive a notification of your request to be associated,” adds Marini. “The owner can see who is making the request, and then approve or deny the request appropriately. That’s all there is to it! (Note: if this checkbox isn’t available, it may be because there’s no current owner of the site or you already have an outstanding association request).”

The addition of this feature seems like a no-brainer, but either way, it’s here now.

According to the Mozilla Security Blog, Firefox 16 features a security vulnerability that allows “a malicious site to potentially determine which websites users have visited and have access to the URL or URL parameters.” Fortunately, Mozilla hasn’t seen the vulnerability being exploited in the wild by ne’er-do-wells.

In response, Mozilla has pulled from Firefox 16 from widespread release. The Firefox site now features a link to download Firefox 15.0.1. For now, Mozilla suggests that users downgrade to this version until they can get a fix up. The browser will be automatically updated with the fixed version of Firefox 16 once it becomes available later today.

The discovery of this vulnerability highlights the need for more beta testers of Firefox releases. You can download the beta here. If you’re feeling really adventurous, you can also try out the Nightly builds of Firefox to help test far off future versions of the browser.

Firefox 16 for Android was also affected by this vulnerability, but a patched version of the browser is already out.

We’ll update this story to let you know when the updated version of Firefox 16 is available. As stated, some users will be automatically updated. Others will have to download it manually. The vulnerability is unlikely to affect you, but it’s better to be safe than sorry.

UDPATE: Mozilla just dropped us a line saying that Firefox 16.0.1 is now available. You can grab it here. Most Firefox users will have been automatically upgraded to the newest version already.

Apple said that some developers have had early access to the iPhone 5 and found that developing for it was a breeze. One of the apps shown off was buit by CNN. They used the increased real estate to show more text. It’s expected among Android users who have been using larger displays for a while now, but it’s a big boost for iPhone owners who have always wanted a larger screen.

Of course, some developers can’t just change their app in a matter of days before the launch of the iPhone 5. Some developers have other jobs that might hinder them from being able to fix up the app before the launch. What about them? Apple says that older apps will run in letterbox mode until they are fixed up. It’s a nice solution to preserve aspect the native aspect ratio of older iPhone apps.

Expect developers to jump on the iPhone 5′s larger screen just as fast as they did the new iPad’s retina display. Consumers are going to expect a native experience out of the box. Developers would be wise to get their apps up and ready for the increased resolution as soon as possible.

It’s a thirty-minute video, but there’s a full transcript on the video page, if you don’t want to watch the entire thing.

“As the number of businesses that turn to Twitter to keep in touch with their customers grows, so does the variety of their needs,” says Doug Williams, Twitter’s Manager for Business Development. “We hear continually from companies looking for tools to help them engage with customers, understand what people are saying about them on Twitter, and learn more about their followers so they can share more valuable, timely content.”

“Meanwhile, there is a thriving ecosystem of Twitter developers building products and services that address these needs and help businesses grow,” adds Williams.

In fact, Twitter has been at the center of a fair amount of controversy regarding how it has been treating developers. The company recently released a new version of its API, bringing more regulation to third-party apps.

Twitter stopped displaying the names of third-party clients in tweets, for one.

“Twitter’s latest change, removing the branding of which source or app consumers use to post tweets sends the message that Twitter wants to protect its content and make a clear distinction between tweets that are sponsored and those posted from social hubs and third-party apps,” Jeff Tinsley, CEO of MyLife, tells WebProNews.

For those worried about a loss of branding, the certification program could help to some extent, if they can manage to get certified.

Under the new program, Twitter has three categories, each of which has a seal: Engagement, Analytics, and Data Reseller:

Twitter has launched the program with twelve partners: Attensity, Crimson Hexagon, Dataminr,DataSift, ExactTarget, Gnip, HootSuite, Mass Relevance, Radian6, SocialFlow, Sprinklr and Topsy.

The company says it intends to add more partners, particularly in these three areas.
