cables is different in operation. In fact, the use of telephone cables is changing. Many new systems use four pairs of unshielded twisted pair wires that are the same as those of digital networks. The residential data communication cable is a typical 4-to 100 Ω cat5e or cat5e twisted pair cable. It can be connected to the indoor wall outlet from the disconnects mounted from the network interface device out
represented since 2000. Due to the development of communication networks and the emergence of cat5e and cat6 cables, the related standard TIA/EIA-568-B and ISO/iec11801:2000 have successively appeared, and high-speed Ethernet is widely used.
With the increase of intelligent engineering in China, the quality of cabling construction becomes more and more important. With reference to international and domestic standards, the Ministry of Construction iss
With the development of science and technology, the price of computer is getting lower, the performance is getting better, the transmission speed of LAN is more and more fast, and the transmission medium of LAN has shifted from coaxial cable to twisted pair and optical fiber, twisted-pair line from the initial CAT1, CAT3, CAT5 to the present CAT5e, CAT6 CAT7.
Although the performance of twisted pair has been continuously improved, but there is a para

In CentOS 7.3, how does one create an rpm file ?, Centosrpm
Take a general disk detection software sas3ircu as an example to see how to package a binary file into an rpm file and then run rpm-ivh xxx. rpm installs the rpm file to the system.
CentOS 7.3 is used. The steps are as follows:Step 1. install three necessary rpm package production software
yum install rpm-build yum install rpmrebuild yum install rpmdevtoolsStep 2. Run the command to generate the rpmbuild directory in the curre
just show you how to use the original RPM (Rpmbuild) tool to hit the RPM package.As with the previous Deb package using Fakeroot, the Rpmbuild is also a sandbox way to build packages, and the process may be more automated in addition to the cumbersome control files. The working directory for building RPM packages is/usr/src/redhat by default, which may be/usr/src/rpm if you install the RPM package under Debian. You can use the RPM--eval%_topdir to view your rpm working directory.

packaged source code package. That means you need to manually unpack and compile the installation. But it can be used directly: Rpmbuild --rebuild xxxxx.src.rpm, to directly compile the source code rpm package into a normal binary RPM package. After executing the above command, you can go to the/USR/SRC/REDHAT/RPMS/ A usable binary RPM package is found in the I386 directory. This type of package has the following kinds of installation methods:
Method 1:

Supplemental 1:-v is a generic parameter (General OPTIONS), that is, verbose, that is, query, install, upgrade, This parameter can be added to the unload. Add 2: When uninstalling packages, if you encounter a dependent package, use--nodeps (don't check dependencies before uninstalling the Packages.), which means that software that uses the software package may not work properly after it is unloaded without checking dependencies. Add 3: If you encounter a package to install. src.rpm, su

Automatic conversion of image format, for example, Ceph is using RAW format, if we upload QCOW2, create a virtual machine, we will experience a upload download process, the speed is unusually slow. And the raw format is usually the original size, upload time is very slow, completely can be uploaded by the small image automatically converted to the specified format.

The output is blob: xxxx-xxx -- xxx # frament...
Simply put, you can use the FileReader () Class in the File API to assign a large Blob, readAsDataURL, or binary File to img src or another one.
You can also dump blob to blob url. The official expression is ObjectURL.
How to Understand?
This URL is a memory-level pointer, but can be called by webpages. Its behavior is similar to that of common files from servers.

If you want to view the files under Infer-out/specs, you can use the inferprint command command
Inferprint Specs File
For example, if we look at the Infer-out/specs/hello_hello.specs file, we can execute the following command:
Inferprint Infer-out/specs/hello_hello.specsThe results are as follows:
