activate your own special effects function
Many people in order to improve the sound effects of music, can be said to be racking their brains to do. But they often do not know is, in fact, a lot of software from the relevant functions, users need to activate these functions can experience a different feeling. Windows Media player playback software, for example, comes with a series of special effects features.
First, open the Windows Media Player playback software, click the right mouse button
cluster's equalization policy. The administrator binds the tag to the scope of the slice key and binds the tag directly to the Shard, and the equalizer distributes the data that satisfies the tag directly to the Shard to which it is bound. and ensure that the data that satisfies the tag is stored on the corresponding shard.Tags are the first condition that controls the behavior of the equalizer and the dis
The default music player on Debian 7.0 is Rhythmbox. At the first look, it appearance seems not so bad. Although it has the problem of displaying Chinese characters, this can is solved by changing the Exec line in

Select the slice key to enable fragmentation.
Note: In the existing set of fragments, you need to ensure that the TAB key on the index, if not, you need to create first.
A very important component in the MongoDB fragment is called The Equalizer (balancer), which is actually played by MONGOs. The equalizer
Locality and causes some datanode to be relatively busier.The Equalizer is a Hadoop daemon that moves blocks from the busy DN to the relatively idle DN while persisting in the block replica placement strategy, spreading the replicas to different machines, racks.It is recommended to perform the equalizer regularly, such as daily or weekly.(1) Run the equalizer wi
In MongoDB (version 3.2.9), the distribution of data refers to splitting the collection data into chunks (chunk) and distributing them on different shards (shard). There are 2 main ways to distribute data: Balanced distribution based on the number of blocks (chunk) and directed distribution based on the Slice key range (range). The MongoDB built-in equalizer (balancer) is used to split blocks and move blocks, automatically achieving uniform distributi

However, depending on the different equipment, HDMI is sometimes not the best choice, if your family's equipment has a certain age, and just need to sound bar such a simple sound output device to connect to the TV, then the fiber audio is a good way to connect. In this case, sometimes the only option is not to worry too much about HDMI. For most simple sound devices, fiber and HDMI are actua
