Unlike and and or, which are binary operators, the not operator is unary, meaning that it operates on one operand. This operand must always be on the right side. Now it’s time to take a look at how the operators work in practice. Here are a few examples of using the and operator ...
The map() function also operates lazily, meaning memory won’t be an issue if you choose to use it in this case: Python >>> sum(map(lambda number: number * number, range(1_000_000_000))) 333333332833333333500000000 It’s up to you whether you prefer the generator expression or map...
There's an old tool for the Windows® 95 series of operating systems that's known the as Automatic Skip Driver. Your first reaction to the tool may have been to its clumsy name, and you may even have suspected that the letters ASD started out meaning something else. And you'd have ...
In soft real-time, the system is expected to meet its deadline, but nothing bad happens if it is occasionally late. The chapter describes the examples of both hard and soft real time systems. Real-time systems are said to be event-driven, meaning that a primary function of the system ...
Dynamic flow control is based on the values of varying inputs, meaning that each fragment can execute the code differently. This is much more powerful than static flow control but can cost performance, especially if the code flow changes erratically between shader invocations. 3.4 可编程着色与...
While many of the tasks in a typical real-time system are periodic in nature, others are asynchronous, meaning it is not possible to plan prior to execution when the corresponding event handlers need to be "fired." Examples of asynchronous events include opening of a door or window, depressio...
The motion of a fluid is often expressed in terms of its local velocity u as a function of position and time. In computer animation, fluid is commonly modeled as inviscid (that is, more like water than oil) and incompressible (meaning that volume does not change ov...
The serial data stream is time-division multiplexed (TDM), meaning that the same physical line can carry more than one type of information in serial order. In the case of the AD1847 application on EZ-Kit Lite, initiated in the last issue, the serial line carries both left- and right-...
instantly rocketed to the heights as the absolute authority on these subjects throughout the Western World. It remains the single most comprehensive resource on the meaning of the Constitutional term “capitation”… Smith deplores capitations as inequitable, inflationary, counterproductive, and destructi...
Figure 2, GPU packet acquisition happens in real time. Through DOCA Flow, flow steering rules are applied to the Ethernet receive queues, meaning queues can only receive specific types of packets (TCP, for example). Morpheus launches a CUDA kernel, which performs the following steps in a...
