• mysql workbench test connect fail (mysql), but mysql could

  I want to learn mysql. It is a bit difficult to read table columns in terminal, so I try mysql workbench. I install workbench from "Ubuntu Software". I could connect from terminal, but not in workbench. Please help.

  I am using:

  Ubuntu 18.04 LTS 64-bits (login as normal user)

  mysql Community edition

  • filename: mysql-8.0.13-linux-glibc2.12-x86_64.tar.xz
  • version: mysql Version 8.0.13 for linux-glibc2.12 on x86_64 (MySQL Community Server - GPL)
  • start by: mysqld (at terminal)

  mysql workbench

  • version: Workbench 6.3 Version 6.3.8 build 1228 CE (64 bits) Community

  I could connect through terminal: mysql -u root -p --host=localhost --port=33060. Port 33060 is prompted by mysql when starting it.

  Thank you.
• extract and delete files from one tar and add to another new one

  I have a bzip2ed tar file and a text file with a list of files. I want to extract the files listed in the text file from the tar, add them to a new tar, and then delete them from the first tar.

  For example, if I have a tar file like this:

  $ tar -tvf test.tar.bz2
  drwxrwxrwx nacho/nacho       0 2018-11-16 23:30 one/test/
  -rw-rw-rw- nacho/nacho       0 2018-11-16 23:25 one/test/a
  -rw-rw-rw- nacho/nacho       0 2018-11-16 23:25 one/test/b
  drwxrwxrwx nacho/nacho       0 2018-11-16 23:25 one/test/c/
  -rw-rw-rw- nacho/nacho       0 2018-11-16 23:25 one/test/c/a
  -rw-rw-rw- nacho/nacho       0 2018-11-16 23:25 one/test/c/b
  drwxrwxrwx nacho/nacho       0 2018-11-16 23:25 one/test/c/c/
  -rw-rw-rw- nacho/nacho       0 2018-11-16 23:25 one/test/c/c/a
  -rw-rw-rw- nacho/nacho       0 2018-11-16 23:25 one/test/c/c/b
  drwxrwxrwx nacho/nacho       0 2018-11-16 23:25 one/test/c/d/
  -rw-rw-rw- nacho/nacho       0 2018-11-16 23:25 one/test/c/d/a
  -rw-rw-rw- nacho/nacho       0 2018-11-16 23:25 one/test/c/d/b
  drwxrwxrwx nacho/nacho       0 2018-11-16 23:34 one/test/e/
  

  And a text file with a list of files like this:

  $ cat files_to_extract
  one/test/b
  one/test/e/
  one/test/c/b
  one/test/c/d/a
  

  After it is done, this is what the original tar file should look like:

  $ tar -tvf test.tar.bz2
  drwxrwxrwx nacho/nacho       0 2018-11-16 23:30 one/test/
  -rw-rw-rw- nacho/nacho       0 2018-11-16 23:25 one/test/a
  drwxrwxrwx nacho/nacho       0 2018-11-16 23:25 one/test/c/
  -rw-rw-rw- nacho/nacho       0 2018-11-16 23:25 one/test/c/a
  drwxrwxrwx nacho/nacho       0 2018-11-16 23:25 one/test/c/c/
  -rw-rw-rw- nacho/nacho       0 2018-11-16 23:25 one/test/c/c/a
  -rw-rw-rw- nacho/nacho       0 2018-11-16 23:25 one/test/c/c/b
  drwxrwxrwx nacho/nacho       0 2018-11-16 23:25 one/test/c/d/
  -rw-rw-rw- nacho/nacho       0 2018-11-16 23:25 one/test/c/d/b
  

  And what the new tar file should look like.

  $ tar -tvf new.tar.bz2
  -rw-rw-rw- nacho/nacho       0 2018-11-16 23:25 one/test/b
  -rw-rw-rw- nacho/nacho       0 2018-11-16 23:25 one/test/c/b
  drwxrwxrwx nacho/nacho       0 2018-11-16 23:34 one/test/e/
  -rw-rw-rw- nacho/nacho       0 2018-11-16 23:25 one/test/c/d/a
  

  Note, the order of the files is irrelevant.

• How to deploy multiple Lambda's CFN Template through Codepipeline?

  Usecase

  I have a cloudformation Stack with more then 15 Lambdas in it. I can able to deploy the stack through Codepipeline which consists of two stages CodeCommit and CodeDeploy. In this approach all my lambda code is in cloudformation template(i.e.inline code). For Security concerns i want to change this Inline to S3 which inturn requires S3BucketName and S3Key.

  As a temporary workaround

  As of now i am zipping each lambda file and passing manually S3keyName and bucketname as a parameters to my stack .

  Is there any way possible to do this step via Codepipeline ?

  My Assumption on CodeBuild

  I Know we can use the CodeBuild for it. But upto now i have seen CodeBuild is only used to build package.json file. But in my usecase i dont have any . And also i can see it is possible to specify cloudformation package command to wrap my lambda from local to S3 this command will generate S3 codeuri`, but this is for Serverless Applications where there will be single lambda but in my case i have 15.

  What i had tried

  I know that as soon as you give a git push to codecommit it will keep you code in S3. So what i thought is to get the S3BucketName and S3KeyName from the codecommit pushed file and pass these parameters to my CFN template. I can able to get the S3BucketName but S3KeyName i dont know how to get that ? And i dont know whether this tried apporach is a workable one ?

  BTW i know i can use shell script just to automate this process. But is there a way possible to do it via CODE PIPELINE ?

  Any help is appreciated Thanks

• Building Enet swig wrap with g++ shows this weird error

  Error when building the.c file

  At the first I've tried to build this on Windows but it also have an error (really weird dependency error), and then I ask my friend and it said that dependency is only available on linux based os. so I decided to build it on my ubuntu os. And I got this really weird error.. (please see the included image file), got any idea why?

  also here's my .i (module) file for swig

  %module java_enet
  //%typemap(in) void* = char*;
  //%typemap(in) const void * = const char *;
  //%typemap(in) void const * = char const *;
  //%typemap(in) enet_uint8 * = char *;

  #include "callbacks.h"
  #include "enet.h"
  const char * ConvertToString(enet_uint8 * data) {
    return (char *) data;
  }
  const char * getStringData (const ENetPacket* packet) {
    char zero = 0;
    memcpy(packet->data + packet->dataLength - 1, &zero, 1);
    return (char*)(packet->data + 4);

    if (packet->data == NULL) return "";
    return SWIGV8_STRING_NEW2(packet->data, packet->dataLength);
  }
  */
  
  const char * ConvertToString(enet_uint8 * data) {

    return (char*)(packet->data + 4);
  }

  Also if you're a good person. Can you please try to build this by ur own?. Its kinda easy to build you only need to use swig -java java-enet.i and then build the c wrapper file using g++ using this command g++ -c java-enet_wrap.c -I /usr/lib/jvm/java-8-openjdk-amd64/include -I /usr/lib/jvm/java-8-openjdk-amd64/include/linux Thanks!

• How to set the health-check-type of an auto-scaling-group created by elastic-beanstalk as ELB programmatically?

  I just followed this tutorial to learn how to use eb command.

  One thing I want to do is to modify the Health Check Type of the auto scaling group created by Elastic-Beanstalk to ELB. But I just can't find how to do it.

  Here's what I have done:

  1. Change the Health Check Type of the environment dev-env to ELB through the AWS console.

  2. Use eb config save dev-env --cfg my-configuration to save the configuration file locally.

  3. The ELB health check type doesn't appear inside .elasticbeanstalk/saved_configs/my-configuration.cfg.yml file. This means that I must specify the health check type somewhere else.

  Then I find another article saying that you can put the health check type inside .ebextensions folder.

  So I make a modification to eb-python-flask, which is the example of the tutorial.

  Here's my modification of eb-python-flask.

  I thought that running eb config put prod, and eb create prod2-env --cfg prod with my eb-python-flask would create an environment whose health-check-type of the auto scaling group is ELB. But I was wrong. The health check type created by the eb commands is still EC2.

  Anyone know how to set the health check type programmatically?

  I don't want to set it through AWS console. It's inconvenient.

• Why Graphicsmagic produces thumbnails much larger in file size that Imagemagick?

  input.jpg is 3264×2448 px, 1.78 MB.

  I have created two thumbnails with identical arguments, in imagemagick 7.0.8-11:

  convert input.jpg -quality 50 -thumbnail 200x200 thumb_im.jpg
  

  and graphicsmagick 1.3.30:

  gm convert input.jpg -quality 50 -thumbnail 200x200 thumb_gm.jpg
  

  The results are: imagemagick — 4.31 kB, graphicsmagick — 27.8 kB. Visually these images are similar in quality but not identical.

  What am I missing?
