Simulates a low bandwidth, high-latency network connection

slow

This bash script offers quick shortcuts to simulate slower network connections. It is useful when you need to simulate a wireless network on a Linux network server, especially when you are using a virtual machine guest on your local machine or in the cloud.

slow 3G                   # Slow network on default eth0 down to 3G wireless speeds
slow reset                # Reset connection for default eth0 to normal
slow vsat --latency=500ms # Simulate satellite internet  with a high latency
slow dsl -b 1mbps         # Simulate DSL with a slower speed than the default

slow modem-56k -d eth0 # Simulate a 56k modem on the eth1 device. eth0 is unchanged.

Create an AWS API Gateway with a POST method on the root resource targetting a given Lambda

Description

This helps creating an AWS API GW with a POST method on the root resource (i.e /) targetting a given Lambda.

The current Terraform documentation is exposing a Mock integration. Thus, a few options are missing when wanting to expose a Lambda integration instead.

There are a few things to know:

1. Add the integration HTTP Method

First of all, you will need to add the integration_http_method alongside the http_method, as in:

delete all aws log groups

specify the region

export AWS_DEFAULT_REGION=ap-northeast-1

awk '{print $2}' | grep -v ^$ | while read x; do  echo "deleting $x" ; aws logs delete-log-group --log-group-name $x; done

only delete loggroup name starting with /aws/lambda
