홈페이지 가보니 PyOpenGL_accelerate 패키지를 안깔아서 그런가?

Downloading and Installation
The easiest way to install PyOpenGL is using pip

$ pip install PyOpenGL PyOpenGL_accelerate

ECDHE?

node.js 에서 내용을 못 까길래 이상하다 싶어서 보는데 나온 용어.

혹시 node.js 에서 TLSv1.3을 지원하지 않기 때문인가.. 정책상 못풀게 되어 있어서 못 건드는걸까?

Perfect Forward Secrecy was optional up to TLSv1.2, but it is not optional for TLSv1.3, because all TLSv1.3 cipher suites use ECDHE.

TLSv1.3 does not support renegotiation.

proxy error: Error: write after end

흐음.. 왜 안써지냐..

기본 예제로는 response.end(data) 식이었고..

얘는 response.write(data, endcoding); response.end(callback); 두개 문장으로 실행되는 유사한 효과를 준다는데

그럼 되는거 아닌가? ㅠㅠ

response.end([data][, encoding][, callback])#

History

data <string> | <Buffer>
encoding <string>
callback <Function>
Returns: <this>

This method signals to the server that all of the response headers and body have been sent; that server should consider this message complete. The method, response.end(), MUST be called on each response.

If data is specified, it is similar in effect to calling response.write(data, encoding) followed by response.end(callback).

If callback is specified, it will be called when the response stream is finished.

node.js 시그널 핸들링과 reload

process.on 으로 시그널 핸들러를 연결해두는 듯

var cluster = require('cluster');

console.log('started master with ' + process.pid);

//fork the first process
cluster.fork();

process.on('SIGHUP', function () {
  console.log('Reloading...');
  var new_worker = cluster.fork();
  new_worker.once('listening', function () {
    //stop all other workers
    for(var id in cluster.workers) {
      if (id === new_worker.id.toString()) continue;
      cluster.workers[id].kill('SIGTERM');
    }
  });

spring war와 war.original

maven 에서 repackging 이라는걸로 인해서 이렇게 바뀐다는데

file로 보면 war는 data과 war.original은 zip archive data 라고 되어있는데 무슨 차이인지 감이 안오네..

The answer is that you are using repackage goal in your spring-boot-maven-plugin. So, What it does?

Maven first builds your project and packages your classes and resources into a WAR (${artifactId}.war) file.

Then, repackaging happens. In this goal, all the dependencies mentioned in the pom.xml are packaged inside a new WAR (${artifactId}.war) and the previously generated war is renamed to ${artifactId}.war.original.

[링크 : https://stackoverflow.com/.../why-spring-boot-generate-jar-or-war-file-with-original-extention/43641913]

[링크 : https://docs.spring.io/spring-boot/docs/current/reference/html/build-tool-plugins-maven-plugin.html]

[링크 : http://repackage.org/]

Repackages existing JAR and WAR archives so that they can be executed from the command line using java -jar. With layout=NONE can also be used simply to package a JAR with nested dependencies (and no main class, so not executable).
