1. LINA Cross-platform Linux Binaries OSCON 2007

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

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

20. PART TWO - Where LINA's Going

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:ocuments~nne 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

37. PART THREE What LINA means for Linux

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

40. LINA – open source everywhere openlina.org
