The performance gap widens quickly between the techniques as the number of conditions increases.Best case scenario with two optionsUse If-then/else statements when?? 1:the data values are character values?? 2:the data values is not uniformly distributed?? 3:there is few conditions to check.Use SELECT statements when?? 1:you has a long seri

How to install OBS Studio 18.04 in Ubuntu 16.04/21.1
OBS Studio is a free open-source live streaming and screen recording software. It has 21.1 versions a day ago. The following describes how to install Ubuntu 18.04, Ubuntu 17.10, Ubuntu 16.04, and/or Ubuntu 14.04.
OBS Studio 21.1 changes include:

In recent years, unsupervised learning has become the focus of research, with little left to be picked with supervised learning of low branches of fruit. The models of VAE (variational auto-encoder, variable-encoder) [1,2] and GAN (generative adversarial Networks) are becoming more and more concerned.
The author has also been studying the knowledge of VAE (from the perspective of depth learning). First of a

OBS is an open source coded push-flow tool that is easy to use and very popular.In one project, it was found that 32-bit OBS streaming CPU utilization was 100% under this desktop I3 processor. The third-party device used in 64-bit, the performance is better.Therefore, the 64-bit OBS needs to be compiled and the corresponding 64-bit plugins compiled.Compile the 64

encode| Code | Scripting Encoder is a simple command-line tool that enables script designers to encode the final script so that Web hosts and Web clients cannot view or modify their source code. Note that this code only prevents others from accidentally looking at your code, and does not prevent a deliberate hacker from viewing your encoded content and its methods.

The following is a short example that contains JScript code that needs to be protected:
The page, which is run after the script encoder, looks like this:
Important: After coding, if you change the encoded text, even if only one word change. The integrity of the script is lost and can no longer be used.
As the operation of the frequency upgrade machine needs automatic leveling function, so start to do this work. Hardware selection is incremental encoder, 100 pulses per revolution, and later learned that each timer of the STM32 Channel 1 and Channel 2 built-in Quadrature encoder module, can be used directly. Before the company engineers are using a timer to capture the pulse, and then self-processing, I loo

You can do this: int error;Opusencoder *enc;ENC = opus_encoder_create (Fs, channels, application, error); From there, the enc can be used to encode the audio stream. Th
