Easy way to convert MKV to MP4 with ffmpeg

Converting mkv to mp4 with ffmpeg

Essentially just copy the existing video and audio stream as is into a new container, no funny business!

The easiest way to "convert" MKV to MP4, is to copy the existing video and audio streams and place them into a new container. This avoids any encoding task and hence no quality will be lost, it is also a fairly quick process and requires very little CPU power. The main factor is disk read/write speed.

With ffmpeg this can be achieved with -c copy. Older examples may use -vcodec copy -acodec copy which does the same thing.

These examples assume ffmpeg is in your PATH. If not just substitute with the full path to your ffmpeg binary.

Configure Git to use a proxy

Configure Git to use a proxy

In Brief

You may need to configure a proxy server if you're having trouble cloning or fetching from a remote repository or getting an error like unable to access '...' Couldn't resolve host '...'.

Consider something like:

Setup a secure (SSH) tunnel as a systemd service. #systemd #ssh #ssh-tunnel #ssh-forward

README

Create a template service file at /etc/systemd/system/secure-tunnel@.service. The template parameter will correspond to the name of target host:

[Unit]
Description=Setup a secure tunnel to %I
After=network.target

Don't use VPN services.

Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

  • A Turkish translation can be found here, contributed by agyild.
  • There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.

Remove duplicates from js array (ES5/ES6)
var uniqueArray = function(arrArg) {
return arrArg.filter(function(elem, pos,arr) {
return arr.indexOf(elem) == pos;
});
};
var uniqEs6 = (arrArg) => {
return arrArg.filter((elem, pos, arr) => {
return arr.indexOf(elem) == pos;
});

There are 3 plugins for generating to create a JAR-File in maven:

  • maven-jar-plugin
  • maven-assembly-plugin
  • maven-shade-plugin

maven-jar-plugin:This plugin provides the capability to build and sign jars.But it just compiles the java files under src/main/java and /src/main/resources/.It doesn't include the dependencies JAR files.

<!--exclude all xml files from the jar-->
<plugin>
