Deleting Multiple Messages from Google Voice

Sat, 13 Feb 2021 14:22:41 +0000

Update: This is no longer the case. Google voice app now has a multi-select and delete button

If you wanted to delete a bulk of messages in google voice, you’re out of luck. Once you select multiple messages, it doesn’t show you a delete button. Only the archive button.

You have to open individual messages and select delete from the drop-down and click a confirmation box for every single message. But, if you want to delete multiple entries of anything else, say voicemails, you can do so.

Java Config with YAML

Thu, 06 Jun 2019 23:21:35 +0000

If you have ever worked with Spring Framework in Java, know the comfort and flexibility of the application configuration that comes with Spring.

Have the configuration stored in properties or YML files
Overriding default configuration based on profiles
Overriding that with environment variables

Adding to these it also has other ‘springy’ features like value injection and couple of other property sources. But if you need a small, light weight, handy application you definitely don’t want to go with a spring boot application. Spring-boot apps are known to have a delayed startup and leaves you with a bulky jar.
