Language:
The Brainfuck programming language consists of eight commands:
> Increment the pointer.
< Decrement the pointer.
+ Increment the byte at the pointer.
- Decrement the byte at the pointer.
. Output the byte at the pointer.
, Input a byte and store it in the byte at the pointer.

In the process of creating my first toy language, I have created the base grammar for it (which can surely be improved upon, feel free to comment). I am emitting C at the moment.
\begin{align}
program &\rightarrow (declaration | stmt)^* \\
declaration &\rightarrow \textbf{let}\ assignment...

This script is a further development of Finding crude death rate and age-standardized death rates from data. In reflection to the kind reviews I created a module for the data; saved the data in dictionaries, with the age groups signified as keys; improved variable names; added function definition...
The container should be thread safe and provide lazy load of data, and cache the data for set period of time.
public class TimeBasedExpirationCache<T> {
private static class CacheElement<T> {
private final Future<T> data;
private final Instant created;
private CacheEl...0
Whilst writing an interpreter for Brainfuck, I had collapsed sequences of .......... to a single instruction OP_PUT (10) (Note that the . instruction in Brainfuck corresponds to a putchar() call in C. Say the byte at the current cell in Brainfuck was 'h', OP_PUT (10) would print h to stdout 10 ti...
I have written an example code to map strings to arrays of unsigned char that contain bytecodes:
#include <iostream>
#include <string>
#include <map>
#define ARRAYSIZE(arr) (sizeof(arr) / sizeof(*arr))
static unsigned char A_[] = { 0x01, 0x02, 0x03 };
static unsigned char B_[] = { 0x04, 0x05, 0...0
