cello - Genetic circuit design automation

•    Java

The Cello input is a high-level logic specification written in Verilog, a hardware description language. The code is parsed to generate a truth table, and logic synthesis produces a circuit diagram with the genetically available gate types to implement the truth table. The gates in the circuit are assigned using experimentally characterized genetic gates. In assignment, a predicted circuit score guides a breadth-first search, or a Monte Carlo simulated annealing search. The assignment with the highest score is chosen, and this assignment can be physically implemented in a combinatorial number of different genetic layouts. The Eugene language is used for rule-based constrained combinatorial design of one or more final DNA sequence(s) for the designed circuit. Verilog programs start with a module keyword, followed by the module name, followed by the list of output and input wire names. Within a module definition, Cello currently parses three forms of Verilog: case statements, assign statements, and structural elements (examples below). Verilog code can be entered using a text editor and saved with a .v extension.

circuitbreaker - Circuit Breakers in Go

•    Go

Circuitbreaker provides an easy way to use the Circuit Breaker pattern in a Go program.Circuit breakers are typically used when your program makes remote calls. Remote calls can often hang for a while before they time out. If your application makes a lot of these requests, many resources can be tied up waiting for these time outs to occur. A circuit breaker wraps these remote calls and will trip after a defined amount of failures or time outs occur. When a circuit breaker is tripped any future calls will avoid making the remote call and return an error to the caller. In the meantime, the circuit breaker will periodically allow some calls to be tried again and will close the circuit if those are successful.
