It should be noted that I only scraped one web page, but this page aggregates headlines from multiple sources. I wanted to see whether the language used by different news sources varies significantly as this information could be relevant to baseline sentiment scores in a trading strategy.  I used the Scrapy web crawling framework in Python to scrape the headlines. Because the page ... Read More

Feed: Planet PostgreSQL. In a lot of PostgreSQL environments, it’s common practice to protect user accounts with a password. Starting with PostgreSQL 10, the way PostgreSQL manages password-based authentication got a major upgrade with the introduction of SCRAM authentication, a well-defined standard that is a significant improvement over the current system in PostgreSQL. What’s better is that almost all PostgreSQL drivers now support this new method of password authentication, which should help drive further adoption of this method.While it may be easy to take advantage of SCRAM authentication in new PostgreSQL deployments, there are a few steps involved in upgrading ...
