One issue that I’ve had for a while has been being logged into multiple aws accounts at the same time with chrome. Incognito mode only works for 1 session, if you launch another incog session and log into another AWS account the first incog session is signed out. This is because incog sessions use the same profile and therefore share the same cookie.

I just discovered how to do this correctly and now have 3 different aws account consoles up at once. What i did was go to ‘chrome -> add person’ which launched a new browser session. I did not sign in. then I did that again. I logged into 3 different AWS accounts using the 3 different chrome profiles running without any trouble.

Live Streaming Instructions

An event (such as a meetup) can be live streamed using the YouTube Live (YTL) service. This was originally called Google Hangouts On Air (GHOA) and was rebranded in 2016. The service is free and works very well.

YTL is very useful for live streaming because it makes the stream available via YT and automatically records and saves on YT.

Another advantage is that the event creator can select what will appear in the stream. This can be the presenter camera, desktop, window or if the presenter joins the YTL event they can stream from their desktop or a slide window. The event creator can then select the presenter stream to go in the output stream.

Rekognition

Amazon announced their Rekognition image analysis service in Nov-2016. The documentation page at that time did not include a specific example of how to use it via the aws cli so I thought that it might be helpful to show an example.

The aws cli must already be setup and usable.

The picture is of my dog laying down and waiting for his dinner.

Replace bucketname and imagename with an s3 bucket and image file that are accessible to the cli.

Postman is an exceptionally useful tool for testing ReST apis.

The following is an example of how to use the xml2Json method in a test if you are getting back xml and want to test elements in the response. The reason that I am posting this is that I could not get xml2Json to work until I discovered (using the new console in Version 4.7.2) that I needed the include the .$. in the object reference.

So that this is completely self contained all this is doing is setting an env var with an xml string, getting that
var, converting it to json and then evaluating the content.

postman.setEnvironmentVariable("testresponse", "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?><myResponse isError=\"false\"/>");

var xmlresponse = postman.getEnvironmentVariable("testresponse");

example of using AppleScript to read a text file with 4 tab delimited fields in it, echo each field in each line and then send that
entry as a new note into Evernote in the notebook called ImportedNotes

Field 1 is just a record number and is not inserted into the note
Field 2 is treated as an Evernote tag (will also be tagged with 'imported_from_notes')
Field 3 is the text of the note
Field 4 is a timestamp in the format of mm/dd/yyyy, the note creation and modification dates will be set to this

example input lines (tabs between each field):

Over time I've developed a lot of AWS configuration informtion and I recently realized that I was not capturing it anywhere.  I've made mods to my security groups once or twice and then did not have a record of what they were before the mod so I've been looking around for a way to get a record of it.  What I've been able to come up with is to use the aws cli (command line interface) and do various describe commands to get it.
To find the commands you can do this: 

    aws ec2 help | grep describe-

You should see something like the following.  It might not be the best way to do it but it's what I've come up with so far.  You can do these in a script, save the output to a file and keep that in your cm system.

       o describe-account-attributes
       o describe-addresses
       o describe-availability-zones
