SLING is a natural language parser for annotating text with frame semantic annotations. It is trained on an annotated corpus using Tensorflow and Dragnn. The parser is a general transition-based frame semantic parser using bi-directional LSTMs for input encoding and a Transition Based Recurrent Unit (TBRU) for output decoding. It is a jointly trained model using only the text tokens as input and the transition system has been designed to output frame graphs directly without any intervening symbolic representation. The SLING framework includes an efficient and scalable frame store implementation as well as a neural network JIT compiler for fast parsing at runtime.


The RC702, nicknamed RC Piccolo, was a Danish micro computer produced by Regnecentralen from 1980. The RC702 had a Zilog Z-80A CPU and 64KB RAM, one or two 5 1/4" floppy disk drives, as well as serial and parallel I/O ports. It ran CP/M and a number of standalone systems like COMAL and UCSD Pascal.

I don't own a RC700 system myself, but I have made an emulator for the RC700, so I can run my old programs from the 80s. If you want to take a quick look, you can try the web-based version of the RC700 emulator.


Sanos is a minimalistic 32-bit x86 OS kernel for network server appliances running on standard PC hardware. The kernel implements basic operating system services like booting, memory management, thread scheduling, local and remote file systems, TCP/IP networking, and DLL loading and linking.

A Win32 layer allows the standard HotSpot JVM to run, essentially providing a JavaOS platform for server applications. It can also be used as a small kernel for embedded network server applications written in C. Sanos has a standard POSIX based API and an ANSI Standard C runtime library.

The kernel was initially developed as part of an experiment on investigating the feasibility of running java server applications without a traditional operating system only using a simple kernel. The sanos kernel is open source and released under a general BSD software license.
