Linux Debug is a functional clone of the old DOS debug.com for x86 linux. Functions include the ability to alter/examine memory and registers, set/clear breakpoints, step into and trace over, symmetric symbolic disassembler, and symbolic assembler. It has a simplified UI, and can work with bin and elf format files. Symbolic functions work only if debug symbols available in the file header. It features a NASM-compatible syntax for both disassembler and single line assembler.
MCU 8051 IDE is a fully featured integrated development enviroment for MCS-51 based microcontrollers. It consists of a compiler, an advanced text editor (with highlighting, validation, and completion), a simulator, a scientific calculator, a hex editor, and many other things. Currently, this program supports only assembly language and a few microcontrollers.
Neko is a high-level dynamically typed programming language. It can be used as an embedded scripting language. It has been designed to provide a common runtime for several different languages. Learning and using Neko is very easy. You can easily extend the language with C libraries. You can also write generators from your own language to Neko and then use the Neko Runtime to compile, run, and access existing libraries. Neko is a good way for language designers to focus on design and reuse a fast and well-designed runtime, as well as existing libraries for accessing filesystem, network, databases, XML, etc. It has a compiler and a virtual machine. The virtual machine is very lightweight and well optimized. The VM can be easily embedded into any application, and your libraries can be accessed using the C foreign function interface.
Nonpareil is a microcode-level simulator for HP calculators introduced between 1972 and 1982, including the HP-35, HP-45, HP-55, HP-25, HP-34C, HP-38C, HP-41CV, HP-11C, HP-12C, HP-15C, HP-16C, and other models. The necessary microcode is included, as is a microcode assembler. The GTK+ toolkit is used for the user interface.
