After a lot of "messing around" with every combination of settings under the sun, I finally got the IOT-ON-OFF IOS Dashboard app working. Success. It's not a "pretty" as Blynk, but in many ways it is much better. For example we can easily switch between dashboards (see image below) and we don't have to pay for "widgets" foreach new app; and with a one time, very small purchase, we can get UNLIMITED widgets and dashboards. Here are some samples from my two previous mini-apps, (1) Wuhan Coronavirus Status and (2) Server Load Averages, all done with MQTT.
It's really quite remarkable if you think about it. I've built these two apps from scratch in two days, and that included wasting a lot of time evaluating and bumping heads with Blynk yesterday (and the headaches that caused).
Later I will summarize my notes on the "tricks" to get the IOT-ON-OFF app working so you don't have to waste your time fiddling around with all the settings. This iPhone dashboard app is not really "super polished" but it's not bad at all.
Hello,
I'm facing a big problem with my hosting server (Dual Xeon 2.4GHz), I'm having a load in the CPU usage and the memory (maybe it's related) ALSO mySQL:

Hi all
what are the ways by which we can know and generate a report of the space remaining, memory(ram) used and the load on the server over a period of time. (1 Reply)
we have an unix system which has
load average normally about 20.
but while i am running a particular unix batch which performs heavy
operations on filesystem and database average load
reduces to 15.
how can we explain this situation?
while running that batch idle cpu time is about %60-65... (0 Replies)
Hello all, I have a question about load averages.
I've read the man pages for the uptime and w command for two or three different flavors of Unix (Red Hat, Tru64, Solaris). All of them agree that in the output of the 2 aforementioned commands, you are given the load average for the box, but... (3 Replies)

Hello I am running a liferay application in tomcat on one of my hosted linux machine having 4GB of ram and 1 CPU.
I get the tomcat response really slow and with much digging I found that the cpu might be loaded and can be tracked with top command.

Currently have two ESP8266 modules testing some Blynk apps, whereI'm not so happy with the Blynk business model for developers, but that's another story.
So, with two of my ESP8266s currently "busy", I decided to work on the ESP32, and in particular the ESPWROOM32.

mac::apps::launch5.18
Launch(3) User Contributed Perl Documentation Launch(3)NAME
Mac::Apps::Launch - Mac module to launch /quit applications
SYNOPSIS
use Mac::Apps::Launch;
my @apps = qw(R*ch Arch MPGP);
my $path = "HD:System Folder:Finder";
LaunchApps([@apps], 1) or warn $^E; # launch and switch to front
LaunchApps([@apps]) or warn $^E; # launch and don't switch
LaunchApps($app, 1) or warn $^E; # launch and switch to front
LaunchSpecs($path, 1) or warn $^E; # use path instead of app ID
QuitApps(@apps) or warn $^E; # quit all @apps
QuitAllApps(@apps) or warn $^E; # quit all except @apps
IsRunning('MACS'); # returns boolean for whether
# given app ID is running
SetFront('MACS') or warn $^E; # set Finder to front
Hide('MACS') or warn $^E; # hide Finder
Show('Finder', 1) or warn $^E; # show Finder (1 == use name)
DESCRIPTION
Simply launch or quit applications by their creator ID. The Finder can be quit in this way, though it cannot be launched in this way.
This module is used by many other modules.
This module as written does not work with MacPerls prior to 5.1.4r4.
"Hide" and "Show" do not currently work on Mac OS X.
Apps that don't have signatures under Mac OS X currently aren't handled, except with LaunchSpecs().
"SetFront" and "IsRunning" can take a four-char creator ID ('MACS'), a bundle ID ('com.apple.Finder'), or a path
(/System/Library/CoreServices/Finder.app). They both optionally take a second parameter which affirms that the data is indeed a path (for
those rare cases where a path might possibly look like a creator ID or bundle ID ... you never know).
"IsRunning" will return the PSN of the application if it is running, which you can then use for targetting the app, or converting to a PID
(with "Mac::Processes::GetProcessPID()"), to send signals to it.
EXPORT
Exports functions "QuitApps", "QuitAllApps", and "LaunchApps", "IsRunning", "LaunchSpecs", "SetFront", "Hide", "Show".
