Flask is a micro web framework written in Python. It is classified as a microframework because it does not require particular tools or libraries. [2] It has no database abstraction layer, form validation, or any other components where pre-existing third-party libraries provide common functions. However, Flask supports extensions that can add ...
The frontend/backend distinction can separate the parser section that deals with source code and the backend that generates code and optimizes. Some designs, such as GCC, offer choices between multiple frontends (parsing different source languages) or backends (generating code for different target processors). [4]
Snap is a software packaging and deployment system developed by Canonical for operating systems that use the Linux kernel and the systemd init system. The packages, called snaps, and the tool for using them, snapd, work across a range of Linux distributions [3] and allow upstream software developers to distribute their applications directly to users.
The non-Python library being called to perform the CPU-intensive task is not subject to the GIL and may concurrently execute many threads on multiple processors without restriction. Concurrency of Python code can only be achieved with separate CPython interpreter processes managed by a multitasking operating system.
Spaghetti code is a pejorative phrase for difficult-to-maintain and unstructured computer source code.Code being developed with poor structure can be due to any of several factors, such as volatile project requirements, lack of programming style rules, and software engineers with insufficient ability or experience.
A number of extensions to the USB Specifications have progressively further increased the maximum allowable V_BUS voltage: starting with 6.0 V with USB BC 1.2, [43] to 21.5 V with USB PD 2.0 [44] and 50.9 V with USB PD 3.1, [44] while still maintaining backwards compatibility with USB 2.0 by requiring various forms of handshake before ...
There are several backends available for CUPS: parallel, serial, and USB ports, cups-pdf [36] PDF Virtual Printing, as well as network backends that operate via the IPP, JetDirect (AppSocket), Line Printer Daemon ("LPD"), and SMB protocols. A new mdns backend in CUPS 1.4 provides Bonjour based printer discovery. [37]
It is further standardized for USB by the USB Implementers Forum as the still image capture device class. USB is the default network transport media for PTP devices. USB PTP is a common alternative to the USB mass-storage device class (USB MSC), as a digital camera connection protocol. Some cameras support both modes.
