Documents are compressed. A partially compressed document is obtained. The partially compressed document includes one or more code words that replace one or more common tokens of a document to be compressed. The one or more common tokens are tokens common to a plurality of documents, and included in a common dictionary. The common dictionary provides a mapping of code words to common tokens. A document associated dictionary is created from non-common tokens of the document to be compressed. The document associated dictionary provides another mapping of other code words to the non-common tokens. A compressed document is created. The creating of the compressed document includes replacing one or more non-common tokens of the partially compressed document with one or more other code words of the document associated dictionary. The compressed document includes the one or more code words of the partially compressed document and the one or more other code words of the document associated dictionary.

Compressing a plurality of documents

In an approach for optimizing read/write access to a document object model in a web browser, one or more computer processors detect one or more accesses to a first data structure of a document object model. Based on the detected one or more accesses, the one or more computer processors determine whether the first data structure is a highly dynamic part of the document object model. Responsive to determining the first data structure is a highly dynamic part of the document object model, the one or more computer processors trigger a conversion of the first data structure to an access optimized data structure. The one or more computer processors convert the first data structure to an access optimized data structure.

Optimized read/write access to a document object model

Migrating a process from a source system with a source operating system to a target system with a target operating system is provided, where the source and target systems or source and target operating system are incompatible. The migrating includes: employing an emulator at the target system to execute code associated with the process being migrated, the emulator performing: translating of system calls and runtime library calls for the source operating system to calls of the target operating system using a system call translator and runtime library translator; translating source application code associated with the process into binary target application code executable on the target system, using a compiler where the source application code has not been translated; and executing the translated binary target application code on the target system, and discontinuing emulation of the process at the target system once the executing begins.

Method and system for migration of processes in heterogeneous computing environments

A cross system secure logon in a target system by using a first authentication system and a second authentication system. A correct password may be valid on the first authentication system and the second authentication system. An aspect includes receiving an input password, generating a first hash key by using the first authentication system, and/or generating a second hash key by using the second authentication system, wherein each authentication system uses a system unique non-collision free hash algorithm. Further, in one aspect, comparing the first hash key with a first predefined hash key of the correct password stored in the first authentication system, and/or comparing the second hash key with a second predefined hash key of the correct password stored in the second authentication system. Furthermore, granting access to the target system based on at least one of the comparisons.
