Success in software development is at least as much about avoiding failure modes as it is about “best practices.” I conjecture it’s because software development on a commercial scale is so hard that almost any mistake will sink a project if left uncorrected or even worse, actively encouraged...
The array type in ts is similar to the definition in java: let list: number[] = [1, 2, 3]; let list: Array<number> = [1, 2, 3]; What is duck typing? duck test. If "walks like a duck and quacks like a duck, then this is a duck". In computer programming, used to 'det...
A user-defined data type (UDT) is a data type that a user can define and derive from an existing data type. Many UDTs have the same internal representation as built-in or source data types. These distinct UDTs increase the number of data types available to support a user's specific requ...
Organizations looking to minimize software bugs should balance the number of rollouts and rollbacks of software releases they do. By doing this, they ensure that the debugging process doesn't get in the way of a consistent software release schedule. This is generally what organizations working in...
Python’s dynamic type system was referred to as duck-typing, which is a kind of implied structural type system — though with some complications. The introduced type hints, however, added a nominative type system. Duck Typing Duck typing is the quintessential aspect of dynamic typing. Effectivel...
The picture below is of what P67/Churyumov-Gerasimenko comet looks when not burning up. It is not quite the ball you might expect, more like a duck or a funny-shaped gun. Comets Orbital Paths Comets take a highly elliptical path whereasplanets are more circular. The picture below shows ...

iCloud is a bit full-- only 12% free-- but that's probably not the problem. Do you have support files at iCloud Drive-- libraries, for instance, that have to be accessed in the background? When you see iCloud disconnect, does it disconnect from your iPhone? Can you see iCloud....
One common caveat about Python is that it’s slow. Objectively, it’s true. Python programs generally run much more slowly than corresponding programs in C/C++ or Java. Some Python programs will be slower by an order of magnitude or more. Why so slow? It isn’t just because most Python...
Pythonic code—when you first hear of it, you might think it is a programming paradigm, similar to object-oriented or functional programming. While some of it could be considered as such, it is actually more of a design philosophy. Python leaves you free to choose to program in an object...
