iwspy is used to monitor a set list of nodes and record the link quality of each of them. The information gathered is the same as that available in /proc/net/wireless: quality of the link, signal strength and noise level. This information is updated each time a new packet is received, so each address of the list adds some overhead in the driver.
Linux also features iwspy, to read the signal, noise and quality of a wireless connection. Other related tools for configuring Ethernet adapters are: ethtool, mii-tool, and mii-diag in Linux and the command dladm show-link in Solaris. The ip suite has a similar purpose and is meant to replace the deprecated ifconfig. [6]
Digital generation loss induced by rotating a JPEG image 90 degrees (from top to bottom) 0, 100, 200, 500, 900, and 2000 times (without using lossless tools) Generation loss is the loss of quality between subsequent copies or transcodes of data. Anything that reduces the quality of the representation when copying, and would cause further ...
[[Category:Image quality templates]] to the <includeonly> section at the bottom of that page. Otherwise, add <noinclude>[[Category:Image quality templates]]</noinclude> to the end of the template code, making sure it starts on the same line as the code's last character.
Upstart operates asynchronously; it handles starting of the tasks and services during boot and stopping them during shutdown, and also supervises the tasks and services while the system is running. Easy transition and perfect backward compatibility with sysvinit were the explicit design goals; [ 4 ] accordingly, Upstart can run unmodified ...
A new study suggests that a person’s cholesterol levels could indicate their risk of developing dementia. Here's what a neurologist wants you to know.
Have you ever gotten yourself in over your head when it came to a home improvement project? I once tried to scrub down the ceiling in my bathroom and ended up shorting out the lights.
Image fidelity, often referred to as the ability to discriminate between two images [1] or how closely the image represents the real source distribution. [2] Different from image quality, which is often referred to as the subject preference for one image over another, image fidelity represents to the ability of a process to render an image accurately, without any visible distortion or ...
