Earlier this year, both Epic Games and CryTech made their Unreal Engine and CryEngine available under an affordable subscription model. These are both very sophisticated game engines that power some high end and popular games. We had previously helped Unity bring Mono as the scripting language used in their engine and we now had a chance to do this over again. Today I am happy to introduce Mono fo

This week, as I was preparing my presentation on C# sung on iOS and Android, I came to the realization that callback-based programming has somehow become an acceptable programming model. It has become an acceptable programming model, in the same way that using IF/GOTO to write programs was an acceptable model back in the 60's. They are acceptable because we did not have anything better to replace

While reading Dave Winer's Why Windows Lost to Mac post, I noticed many parallels with my own experience with Linux and the Mac. I will borrow the timeline from Dave's post. I invested years of my life on the Linux desktop first as a personal passion (Gnome) and when while awoken for two Linux companies (my own, Ximian and then Novell). During this period, I believed strongly in dogfooding our own

After a year and a half, we have finally released Mono 3.0. Like I discussed last year, we will be moving to a more nimble release process with Mono 3.0. We are trying to reduce our inventory of pending work and get new features to everyone faster. This means that our "master" branch will remain stable from now on, and that large projects will instead be developed in branches that are regularly la

Today Microsoft announced TypeScript a typed superset of Javascript. This means that existing Javascript code can be gradually modified to add typing information to improve the development experience: both by providing better errors at compile time and by providing code-completion during development. As a language fan, I like the effort, just like I pretty much like most new language efforts aimed

True story. The hard disk that hosted my /home directory on my Linux machine failed so I had to replace it with a new one. Since this machine lives under my desk, I had to unplug all the cables, get it out, swap the hard drives and plug everything back again. Pretty standard stuff. Plug AC, plug keyboard, plug mouse but when I got to the speakers cable, I just skipped it. Why bother setting up the

Herb Sutter discusses in his Reader QA: When Will Better JITs save Managed Code?: In the meantime, short answer: C++ and managed languages make different fundamental tradeoffs that opt for either performance or productivity when they are in tension. [...] This is a 199x/200x meme that’s hard to kill – “just wait for the next generation of (JIT or static) compilers and then managed languages will b

This was a very interesting year for Mono, and I wanted to capture some of the major milestones and news from the project as well as sharing a bit of what is coming up for Mono in 2012. I used to be able to list all of the major applications and great projects built with Mono. The user base has grown so large that I am no longer able to do this. 2011 was a year that showed an explosion of applicat

The Mono runtime engine has many language interoperability features but has never had a strong story to interop with C++. Thanks to the work of Alex Corrado, Andreia Gaita and Zoltan Varga, this is about to change. The short story is that the new CXXI technology allows C#/.NET developers to: Easily consume existing C++ classes from C# or any other .NET language Instantiate C++ objects from C# Invo

As I meet new Unix hackers using Linux or Mac, sometimes I am surprised at how few Unix tricks they know. It is sometimes painful to watch developers perform manual tasks on the shell. What follows are my recommendations on how to improve your Unix skills, with a little introduction as to why you should get each book. I have linked to each one of those books with my Amazon afiliates link, so feel

Setting up a new company consumes a lot of time. Specially as we are developing as fast as we can not one, but two products: .NET for iPhone and .NET for Android. Structurally, we are better off than we were the first time that we built these products. We have more developers working on each product than we did the first time around, so progress is faster. But we also had to swap the developers ar

I am a fan of Dropbox. It is a great tool, a great product, and clearly they have a passionate team over at Dropbox building the product. Dropbox recently announced an update to its security terms of service in which they announced that they would provide the government with your decrypted files if requested to do so. This is not my problem with Dropbox. My problem is that for as long as I have tr

Almost a year ago we started building a set of Mono bindings for building native MacOS X applications. Our original goals were modest: bind enough of AppKit that you could build native desktop applications for OSX using C# or your favorite .NET language. We leveraged a lot of the code that we built for MonoTouch our binding to the CocoaTouch APIs. During the year, the project picked up steam, we g

Three years ago, we were almost laughed out of the Game Developer Conference Show floor. C# as the heir to C++ back then was mostly an academic discussion. And there were only a few anecdotal examples of developers using C# for fast and safe scripting in games such as Second Life and Unity. Three years ago, C# as a scripting language for games had shared the reputation that Javascript had before t

Now that we feel that we have fixed all the embarrassing bugs in Mono for Android, so we have opened up our Mono for Android preview program to anyone that wants to take it out for a spin. Mono for Android brings the full Mono VM to Android. We use a library profile that is better suited for mobile devices, so we removed features that are not necessary (like the entire System.Configuration stack,

Today Oracle sued Google over Java patents and copyrights that they claim Google's Android OS infringes. The lawsuit claims that Google knowingly infringed on those patents, and that the continued distribution of Google's Android is harming Oracle's Java Business. You can read the actual complaint, the patents referenced are: 6125447 6192476 6530080 6910205 6061520 7426,720 RE38,104 There is also

Before April 8th, developers targeting the iPhone had to deal with this section: 3.3.1 — Applications may only use Documented APIs in the manner prescribed by Apple and must not use or call any private APIs. The above is a pretty reasonable requirement as it gives Apple the chance to not have to maintain and support internal APIs, temporary APIs or APIs that have not fully matured. When iPhoneOS 4

The Mono team is proud to bring you a preview of C# 5.0 a few years before our friends in Building 41 do. A snapshot of the code is available in the demo-repl.zip file. This contains the csharp.exe C# REPL shell and the Mono.CSharp.dll compiler-as-a-service assembly. With Today's code drop all those scenarios now work: Run Mono's C# compiler on .NET Embed Mono's Evaluator in your C# app. Use Mono'

Today we released MonoMac, a new foundation for building Cocoa applications on OSX using Mono. MonoMac is the result of years of experimentation in blending .NET with Objective-C and is inspired by the same design principles that we used for MonoTouch. It is also the result of weekend hacking as our day to day work revolves around Mono's efforts on Linux servers, Linux desktops, Visual Studio inte

It seems that David's article on Windows strategy tax on .NET lacked enough context for my actual quotes in there. When David contacted me, he was writing a piece on the evolution of .NET and since he was speaking to Microsoft, he wanted to get feedback from other people on what we thought Microsoft got right and what they got wrong. This is how my email to David started: Well, I am a bit of a fan

Another nice piece of technology that we showed at the PDC was static compilation, the feature behind allowing Mono to run on the iPhone in a fully legit way (no jail-breaking): Although Mono has supported batch compilation from CIL into native code in the past there was a small amount of code that was still generated dynamically. The intention originally was to help reduce startup and increase co

SwiftNavigation To celebrate that RealityKit's is coming to MacOS, iOS and iPadOS and is no longer limited to VisionOS, I am releasing SwiftNavigation for RealityKit. Last year, as I was building a game for VisionPro, I wanted the 3D characters I placed in the world to navigate the world, go from one point to another, avoid obstacles and have those 3D characters avoid each other. Almost every game

The past 21 days have been some of the most intense hacking days that I have ever had and the same goes for my team that worked 12 to 16 hours per day every single day --including weekends-- to implement Silverlight for Linux in record time. We call this effort Moonlight. Needless to say, we believe that Silverlight is a fantastic development platform, and its .NET-based version is incredibly inte
