The recent computer old hint of space is not enough, is very upset, decided to study, why space so quickly spent., 256 of the space, there are a few g, one of the largest head of the system occupies: 160G, accounted for more than 60%, i le a rub ...Under normal circumstances: we can click on the management to go to the System disk optimization interface:This is useful for simple file occupancy analysis, where we can solve the problem of lack of space by cleaning up documents and recycling bins .

Rnorm Normal distribution (the normal distribution) function
The function Rnorm of the whole distribution function is declared as follows:
Rnorm (n, mean = 0, SD = 1)
N: Produce random number of numbers
Mean: Expectation
SD: Is Variance
Produces 1000 random numbers, obeys the standard normal dist
, these are transparent to the application system.
What are the current distribution strategies? Simply enumerate a few, some are met in the work, some are their own yy, but also basic reliable.

The advantages of seemingly only convenient management, the physical machine in a computer room, if the application machine in multiple machines, it is possible to have a cross room call. If there is a problem
First talk about MySQL data distribution, the most commonly used is replication (replication) technology. There are many middle architectures based on this technique, and the classification is summed up as follows:1, tree structure (master,backup-master,slaves) This structure is the most common one used in the Web system at present. The entire system has 1 write/update points, that is, master;master-backup and slaves are replication Master from the li

In the process of credit scorecard model development, normality is an important index to check whether the model credit score distribution is effective. Normally, the standard normal distr

Exponential family (exponential distribution family) is a common concept, but its definition is not particularly clear, today look at the wiki content, have a general understanding, first and share with you. This article is basically the translation of some content on the wiki.

Tags: conjugate, prior distribution, likelihood function, posterior distributionThe Bounded distribution is a method that greatly simplifies Bayesian analysis. The function of this function is to make the unknown parameters of these distributions give physical meaning before the test when the Bayesian formula contains multiple probability distributions, and continue to the test for convenience of analysis.
A Power distribution System (PDS) is a subsystem that allocates power from power source to each device and device that needs power in the system. In all electrical systems there are power distribution systems, such as the lighting system for a building, an oscilloscope, a PCB, a package, a chip, and a power distribution system inside.

The membership of the distribution group described earlier is static. For example, if a user's mailbox account is added to a distribution group, it always belongs to the group regardless of how the object's properties change. In addition, if a user wants to join a distribution group, they must pass a specific join operation (whether it is an administrator or a us
A typical Linux distribution includes the Linux kernel, some GNU libraries and tools, a command-line shell, a graphical interface of the Xwindow system and the corresponding desktop environment, such as KDE, or GNOME, and contains a large number of office suites, compilers, text editors, Application software such as scientific computing tools.Linux distribution =linux kernel + commercial softwareLinux Commo
First, choose the right Linux distribution
When it comes to Linux releases, too much, and probably no one can give an accurate number, but one thing is for sure, Linux is becoming more and more popular, and in the face of so many Linux distributions, beginners who intend to move from other systems to Linux may be confused, even if the faithful Linux users do not have the time and effort to try each, so beginners in the study of Linux before, need to
