the smoother the data, the closer α is to 0, the closer the smoothing value is to the smoothing value of the first I data. the smoother the data is, the α value can usually be tried several times to achieve the best effect.
The formula for prediction by an exponential smoothing algorithm is: xi + h = si, where I is the coordinate of the last data record, that is, the predicted time series is a straight line, does not reflect the trend and seasonality of time series.

The next step is to hand over the values to MRTG, which is obtained through a configuration file, generally, this configuration file is generated by the MRTG producer maker command, but this time we need to write this configuration file (CPU.

In addition to the electromagnetic radiation severity, high transmission quality requirements such as the use of STP in the wiring, in general, we are using UTP.

It is known that the common twisted pair is connected by four groups of intertwined cables. The so-called wire is the distance between the cable is actually the lengt
How about Kirin 928 processor? The following will be the Kirin 928 processor performance evaluation, Huawei Glory 6 Extreme version of the processor is Kirin 928, then its performance? You can learn through the following.
From Huawei's official release, Kirin 928 is currently the fastest HiSilicon processor, the frequency reached 2GHz, is still a 28n process, support 300Mbps LTE Cat6.
In addition, Kirin 928 of the processor on the GPU is stil
at the Spring forward conference earlier this week, Apple brought us a new MacBook lineup and a Force Touch technology that revolutionized trackpad design. the Force touch introduced four "force sensors" compared to the buttons of the old touchpad. Apple says the Force touch will give the device input feedback based on press pressure and open up a whole new way of interacting-for example, when you're browsing on safari, press it to eject a new wikipedia window.
With four "force sens
Metrics is a Java library that can provide you with unmatched code-run insight.
It was developed by Yammer to detect the health of back-end services on the JVM. Metrics provides a powerful toolset for measuring the behavior of key components in your production environment.
Metrics provides a common set of modular libraries for support such as Guice,jetty,log4j,apache httpclient,ehcache,logback,spring, Also provides comparisons such as ganglia and graphite backend reports.
