. Delphi A simple but effective visual log control/library. The programmer can send messages to a log window from anywhere in his code. The Log window can be set to automatically pop up when an error message is sent to it. Depending on the chosen verbosity level of the log see the Verbosity property low-level messages like verbose/debug messages are shown or not. Contains: Non-visual log TRamLog Visual log TRichLog

. The package features a full x86 disassembler including MMX, 3dNow enhanced, SSE and SSE2 support. The disassembler can examine a single x86 instruction see ParseCode or a full function see ParseFunction and either return a short analysis or a full text disassembly. Register contents are watched/followed if possible, this improves the analyses for jump/call targets. Case/switch jump tables are automatically detected and handled correctly.

. Delphi Lightweight, language-independent software stack for point-to-point RPC implementation. Thrift provides clean abstractions and implementations for data transport, data serialization, and application level processing. The code generation system takes a simple definition language as input and generates code across programming languages that uses the abstracted stack to build interoperable RPC clients and servers. Thrift makes it easy for programs written in different programming languages to share data and call remote procedures. With support for 28 programming languages, chances are Thrift supports the languages that you currently use.
