The name of the capital of an empire should sound like what it is, and to my ear something in the very sound of “Palmyrium” echoed the music of the imperial. How do professional fantasy writers invent names? They use a number of different systems. Some of them, more linguistically ...
Consider the trivially true proposition:“if there is a rational number q whose absolute value is less than the reciprocal of any natural number n, then for every natural number n, there is a real number r whose absolute value is also less than 1/n.” Symbolically we express this as foll...

Some tables hold only 1 data row per user in dynamo but for some tables they can hold more than 10k rows (without real max number). Data for those tables are coming from external IoT sensores hence the big amout of rows. Re. sync expressions - yes, we have started using them recently...
