Easy Text-to-Speech with Python

Image
Text-to-speech (TTS) technology reads aloud digital text. It can take words on computers, smartphones, tablets and convert them into audio. Also, all kinds of text files can be read aloud, including Word, pages document, online web pages can be read aloud. TTS can help kids who struggle with reading. Many tools and apps are available to convert text into speech. Python comes with a lot of handy and easily accessible libraries and we’re going to look at how we can deliver text-to-speech with Python in this article. Source:  https://www.youtube.com/watch?v=eiP-12qHM-c Different API’s are available in Python in order to convert text to speech. One of Such API’s is the Google Text to Speech commonly known as the gTTS API. It is very easy to use the library which converts the text entered, into an audio file which can be saved as a mp3 file. It supports several languages and the speech can be delivered in any one of the two available audio speeds, fast or slow. More detai

Dependencies between DAGs in Apache Airflow

  A DAG that runs a “goodbye” task only after two upstream DAGs have successfully finished. This post explains how to create such a DAG in Apache Airflow In Apache Airflow we can have very complex DAGs with several tasks, and dependencies between the tasks. But what if we have cross-DAGs dependencies, and we want to make a DAG of DAGs? Normally, we would try to put all tasks that have dependencies in the same DAG. But sometimes you cannot modify the DAGs, and you may want to still add dependencies between the DAGs. For that, we can use the  ExternalTaskSensor . This sensor will lookup past executions of DAGs and tasks, and will match those DAGs that share the same  execution_date  as our DAG. However, the name  execution_date  might be misleading: it is not a date, but an instant. So DAGs that are cross-dependent between them need to be run in the same instant, or one after the other by a constant amount of time. In summary,  we need alignment in the execution dates and times. Let'

Better File Storage in Oracle Cloud

Use Oracle Application Express with Oracle Cloud Infrastructure REST APIs to upload, download, and manage big files in Oracle Cloud. By Adrian Png November 27, 2019 Oracle Cloud Infrastructure  provides a comprehensive suite of REST APIs for accessing and managing cloud resources. For example, administrators can use REST APIs to create and manage autonomous databases and initiate backups. Oracle Application Express (Oracle APEX)  makes working with REST easy. The  APEX_WEB_SERVICE  package, available since Oracle APEX 4.0, provides developers with a function for consuming REST APIs. Oracle APEX 5.0 introduced the  APEX_JSON  package, allowing easy parsing of JSON responses. Oracle APEX 18.1 introduced the Web Source Module (WSM), which enables developers to access REST services and use the data in APEX components such as reports, interactive reports, and interactive grids. These features, when used together with Oracle Cloud Infrastructure REST APIs, enable APEX developers
