d3989 | train | You can try a space filling curve and a quadtree data structure. A space filling curve reduces the 2 dimension to 1 dimension and it works best with power of 2 grids. A quadtree divides the plane into 4 quads. A space filling curve is mathematical function taking 2 variables and gives 1 number as result. It can have a... | unknown | |
d3990 | train | Make an array for your month names like so
$montnames = ['', "jan", "feb", "mar", "apr", "may", "jun", "jul", "aug", "sep", "oct", "nov", "dez"];
Trick is to leave first one empty, because months begin with 1 and arrays count at 0.
echo $month[2]; // feb | unknown | |

d3992 | train | My current pragmatic solution which may be okay since only 4 values need to be handled:
public static BitSet transformToBitSet(short[] numbers) {
BitSet data = new BitSet();
int nBit = 0;
for (int i = 0; i < numbers.length; i++) {
short number = numbers[i];
switch (number... | unknown | |
d3993 | train | You can use ESLint's built-in no-restricted-syntax rule to disallow the FunctionExpression and FunctionDeclaration AST nodes:

"rules": {
"no-restricted-syntax": [
"error",
"FunctionExpression",
"FunctionDeclaration"
]
}
}
This doesn't explicitly "prefer" arrow functions, but if you disa... | unknown | |
d3994 | train | You could use the ActivatedRoute service and subscribe to the url observable. Based on the value you get there you decide on what data to load.
Another approach would be to use params in the path, so you would have something like 'submenu/1' and 'submenu/2' where 1 and 2 are an 'id' parameter and in the activated route... | unknown | |

d3997 | train | It's easy to compute the timestamp in milliseconds for now and now-24h so why not do it in your application logic and build the query out of those values?
For instance (in JS),
const now = new Date().getTime();
const now24h = now - 86400000;
const query = `timestamp:[${now24h} TO ${now}]`;
query would contain the foll... | unknown | |

d3999 | train | If you just want to add new event handlers without overwriting the existing event handlers, you can use addEventListener() or attachEvent() (for older versions of IE) instead of setting .onclick, .onsubmit, etc... to add a new event handler without affecting the previous event handlers.
