LINA allows Linux applications to run on multiple platforms like Windows and Mac OS X. It does this by mapping host system resources to their Linux counterparts, allowing Linux apps to run securely in an isolated partition. LINA also includes a simple installer for developers to package complex apps for users to easily install on any system. The goal of LINA is to create a uniform runtime environment and programming model to make applications truly cross-platform.

1. LINA Cross-platform Linux Binaries OSCON 2007

2. Introducing LINA With LINA, Linux binaries run with native look and feel on Windows, Mac OS X, and all flavors of Linux and UNIX.

3. PART ONE What LINA Is

4. LINA in One Sentence LINA is a full-featured Linux virtual operating system that is slim and fast, has no GUI of its own, accesses the libraries of the underlying OS, utilizes the host shell and file system, is robustly integrated through kernel resource mapping, allows apps to run securely on the partitioned kernel, and includes a means for simple installation of complex packages.

5. LINA in One Picture A Picture of LINA

6. Selected Features Breaking it down With LINA Linux applications run cross-platform LINA is integrated with the underlying OS LINA maps system resources Applications run securely on LINA LINA allows simple installation of complex packages

7. Cross-platform Linux Applications Linux applications run without recompiling on Windows, Mac OS X and all flavors of UNIX

8. Cross-platform Linux Applications Benefits Run Linux applications on any operating system Developers write and compile these applications in an ordinary Linux environment

9. Integrated with the Underlying OS LINA silently and invisibly allows Linux applications run with native look and feel on Windows, Mac OS X and all flavors of UNIX

10. Integrated with the Underlying OS Benefits Linux applications look and feel like native application The Linux command line is integrated into the host shell Native integration with no effort for the developer

11. Integrated with the Underlying OS A LINA App running on Linux

12. Integrated with the Underlying OS The same LINA App running on Mac OS X

13. Integrated with the Underlying OS The same LINA App running on Windows XP

14. Resource Mapping LINA maps host resources to their Linux counterparts rather than relying on system call mapping

15. Resource Mapping Benefits LINA apps run as expected on all operating systems Resources of the underlying operating system are mapped to Linux counterparts Developers access these resources as Linux resources

16. Applications Run Securely Each LINA application runs in its own partition of LINA's Linux kernel, isolating it at run time from other applications and from the host

17. Applications Run Securely Benefits Applications running on LINA can't affect each other Applications running on LINA can't affect the host without permission

18. Simple Package Installation LINA includes an installer that allows developers to package applications for instant use on any platform

19. Simple Package Installation Benefits Users install LINA applications with minimal effort Developers easily create application packages using install tools Packages are of arbitrary complexity

20. PART TWO - Where LINA's Going

21. Project Status LINA Today LINA Runtime Environment LINA Tools LINA Build System

22. The Road to 1.0 The next six months Enables the use of GTK and QT GUI libraries The LINA installer More access to host resources

23. A Peek into the Future LINA - the First Cross-Platform Virtual Operating System

24. Platform Evolution Portability Uniform APIs C JAVASCRIPT LINA Uniform Runtime Uniform Environment 1970s - 1990s 1990s - 2000s Now Adoption Example

25. Not a Uniform Environment Apache App1 App2 MySQL Network Stack Lib1 Lib2 ONE BINARY .access

26. Example of Uniform Integration Network Stack /Users/Anne /home/Anne C:\Documents~\Anne Device .access

27. Uniform Integration Apache App1 App2 MySQL . access Network Stack Lib1 Lib2 WINDOWS XP

28. Higher Abstractions A uniform environment enables higher abstractions to be portable RESOURCES KERNEL NETWORK PROGRAMS

29. Internet Application Example Program Program Program 208.75.23.10 10.0.1.28 10.0.1.100 WEB SERVER 10.0.1.156 DATABASE WEB SERVICE

30. The Web Service import mynetwork.mywebservice import mynetwork.databaseprovider MyWebService::MyWebService() { Type<String> addressName = “localhost”; databaseProvider.setAddress(addressName); databaseProvider.setPort(3306); databaseProvider.setDatabase(“postgresql”); }

31. The Operating Systems import mynetwork.servicemanager import mynetwork.mydatabaseserver import mynetwork.mydatabaseprogram MyDatabaseServer::MyDatabaseServer() { Type<MyServerProgram> databaseProgram; Type<Application> postgres; postgres = ServiceManager::find(“Postgres”); postgres.setPassword(“postgres”, “hywsdcs”); postgres.start(); databaseProgram.start(); }

32. The Network import mynetwork.mynetwork” import mynetwork/mydatabaseserver MyNetwork::MyNetwork() { os1 = new MyDatabaseServer() os1.setIPAddress(“10.0.2.2”); os2 = new OperatingSystem() os1.enableDHCP(); os1.setIPAddress(“10.0.2.3”); this.addSimpleServer(os1) this.addSimpleServer(os2) }

33. The Network import mynetwork.mynetwork” int main(int argc, char *argv) { MyNetwork network; network->start(); return 0; }

34. Compiling the Program My Program #include int main() dfsdfa sdfsaf My Network VOS Compiler

35. Beyond the Virtual Machine A virtual operating system language compiles programs into networks, operating systems, and processes My Program

36. The Ground Floor Universal Open Source Binaries A Cross-Platform Virtual OS Programming Language The Binary is a Network Portable Dynamic Language modules

37. PART THREE What LINA means for Linux

38. LINA - the Future of Linux Everyone who installs LINA installs Linux

39. LINA - the Future of Linux Whenever a user installs a Linux application packaged for LINA the user gets Linux Every great Linux application that you package for LINA generates new Linux users
