After the successful installation of Ubuntu(or other linux distro) on your windows machine, you may encounter a lot many issues setting up the Ruby on Rails project and it could be any or all of the below mentioned one:

Error: Could not find database.yml file / issue related to postgres In this case check that you have installed postgresql properly or not on your machine first. Once after confirmation, u may still face the same issue then u may have to find 'pg_hba.conf' file and follow the instructions given in this page https://stackoverflow.com/questions/10845998/i-forgot-the-password-i-entered-during-postgres-installation

We may have to replace the word 'peer' everywhere inside 'pg_hba.conf' file with 'trust' and then save it, restart the psql service and then try to start the rails server again. But before that we have to find the location of 'pg_hba.conf' file. This link might be helpful for the same - https://askubuntu.com/questions/256534/how-do-i-find-the-path-to-pg-hba-conf-from

This histogram shows the distribution of GitHub Gist API response times (in milliseconds) for a sample of 10,000 requests as observed by bl.ocks.org.

The distribution roughly follows a log-normal distribution, which is unsurprising for a complex process that has multiple independently-random sources of delay. The mode response time was in the range 120-140ms, while the median response time was 206ms. The middle 80% of requests were in the range 114-527ms. About 11% of requests took longer than 500ms, and 5% of requests took longer than one second. (The rightmost bin in the histogram includes these long requests.)

Since API endpoints vary dramatically in their computational cost, the distribution of response times is likely multimodal. In this dataset, 96% of requests were for a single gist (/gists/42), while the remaining 4% of requests were to list a user’s gist (/users/fred/gists). By separating the API requests for a single
