Update:

Have noticed that getting the IoT OnOff app (on IOS, I don't have an Android phone) is very difficult for most people, who are not hardish core IT geeks, to connect to an MQTT server.

To set this, I set up another MQTT server without authentication, and could not get IoT OnOff to connect on both server after many tries.

This means that, although I build this app as a public service, it is so difficult for users to get it to work, I did not really accomplish my objective, because of the problems with IoT OnOff, which I have no control over since I am not the developer and I have not found any contact information for the developer except his name (on FB, LinkedIn, email on web site, etc).

To confirm that my MQTT servers are working, I set up Node-RED today, and it connects very easily with both my MQTT servers.

Wuhan Coronavirus Stats for China (from "official" source) using Node-RED:

I like the IoT OnOff app, but most people would consider me in the "uber-IT-guy" or "super-geek" category.

So in the future, unless the connection bugs are worked out in the IoT OnOff app for the iPhone, I will have to find another platform for a rapid-prototype public service app dashboard.

Node-RED might be a candidate (more on Node-Red later), but I will check out some other MQTT visualization dashboard for the web beforehand.

Libravatar::URL(3pm)					User Contributed Perl Documentation				      Libravatar::URL(3pm)

NAME
Libravatar::URL - Make URLs for Libravatars from an email address SYNOPSIS
use Libravatar::URL; my $url = libravatar_url( email => 'larry@example.org' ); DESCRIPTION
See <http://www.libravatar.org> for more information. Functions libravatar_url # By email my $url = libravatar_url( email => $email, %options ); # By OpenID my $url = libravatar_url( openid => $openid, %options ); Constructs a URL to fetch the Libravatar for the given $email address or $openid URL. %options are optional. "libravatar_url" will accept all the options of "gravatar_url" in Gravatar::URL except for "rating" and "border". The available options are... size Specifies the desired width and height of the avatar (they are square). Valid values are from 1 to 512 inclusive. Any size other than 80 may cause the original image to be downsampled using bicubic resampling before output. size => 40, # 40 x 40 image default The url to use if the user has no avatar. default => "http://www.example.org/nobody.jpg" Relative URLs will be relative to the base (ie. libravatar.org), not your web site. Libravatar defines special values that you may use as a default to produce dynamic default images. These are "identicon", "monsterid", "wavatar" and "retro". "404" will cause the URL to return an HTTP 404 "Not Found" error instead and "mm" will display the same "mystery man" image for everybody. See <http://www.libravatar.org/api> for more info. If omitted, Libravatar will serve up their default image, the orange butterfly. base This is the URL of the location of the Libravatar server you wish to grab avatars from. Defaults to <http://cdn.libravatar.org/avatar/> for HTTP and <https://seccdn.libravatar.org/avatar/> for HTTPS. short_keys If true, use short key names when constructing the URL. "s" instead of "size", "d" instead of "default" and so on. short_keys defaults to true. https If true, serve avatars over HTTPS instead of HTTP. You should select this option if your site is served over HTTPS to avoid browser warnings about the presence of insecure content. https defaults to false. LICENSE
