After getting inspired from your highly, I too started, yesterday installed node-red in windows system and created a very basic flow of reading a csv file and reading Earthquake data from tutorial itself as of now Smilie

you are really GREAT in learning things FAST(I.T techs), I have never seen a person learning this much fast honestly saying Smilie

Let me see if I could prepare one and share it here too with all of us Smilie

Thanks,

Thanks Ravinder,

Yes, everyone who knows me well, knows I am a systems engineer at heart love, learning new things and building new apps, cross domain, with new tech. That's just me. I have no "system or domain" religion about tech. It's all use a "tool in the big toolbox" as far as I am concerned.

Thanks for the kind words, Ravinder.

I always try to keep the mind of the beginner, even after many decades of IT experience, and so I keep trying, learning and building new things.

But that approach also can bring criticism from those who love to use (or remain nostalgic for) the same old technology introduced decades (or just a few years) ago, religiously; and my "tech style" also will result in criticism from those who are more of tech "purists".

Honestly, the criticism does not bother nor influence me. Everyone should dance to the music of their own life. To each his or her own, as they say!

Cheers and Thanks Again for the Kind Words, Ravinder!

Anyway, Node-RED is fun and easy to use, I think, especially if you love to program already. I already program "OK" (not great) in Javascript, so this makes Node-RED much easier, I think; and since I already write a lot of PHP code, it's also easy to call PHP scripts (any scripts, actually) from Node-RED as well.

NAME
ndb_print_sys_file - print NDB system file contents SYNOPSIS
ndb_print_sys_file file_name DESCRIPTION
ndb_print_sys_file obtains diagnostic information from a MySQL Cluster system file. Usage ndb_print_sys_file file_name file_name is the name of a cluster system file (sysfile). Cluster system files are located in a data node's data directory (DataDir); the path under this directory to system files matches the pattern ndb_#_fs/D#/DBDIH/P#.sysfile. In each case, the # represents a number (not necessarily the same number). For more information, see MySQL Cluster Data Node FileSystemDir Files[1]. Like ndb_print_backup_file and ndb_print_schema_file (and unlike most of the other NDB utilities that are intended to be run on a management server host or to connect to a management server) ndb_print_backup_file must be run on a cluster data node, since it accesses the data node file system directly. Because it does not make use of the management server, this utility can be used when the management server is not running, and even when the cluster has been completely shut down. Additional Options None. COPYRIGHT
