Today I learned something new that should have been obvious but it was something I never took time to think about. In Linux, we have three standard streams: stdin, stdout, and stderr. If you are familiar with programming in C, you should know that stdin is the input channel that handles data from an input device such as your keyboard. scanf is a function that scans input according to format (definition from SCANF(3) - Linux Programmer's Manual). But how does scanf actually scan the input?

In the latter half of June (when I flee from my parent’s home to Mississauga for 2 months so that I can study and read all I want without being bothered), I decided to read Intermediate Perl: Beyond The Basics of Learning Perl. For those of you who are not familiar with the book, it’s the sequel to the “Llama book” (Learning Perl), a classic book on Perl.

Recently I have been reading up and working on creating a Github App for work to automate some process to create a pull request that contains code changes from various branches. For those of you who are not familiar with Github Apps, a Github App is an app you can install or create to automate your workflow such as giving feedback on issues or pull requests if they don’t meet the guidelines or are missing information. The entire Github marketplace is dedicated to selling apps and actions to automate workflows.

If you are working on a Github App on an Enterprise Edition and encounter an error such as Your Private Key is not Correct, it may not be anything wrong with your private key at all. You just need to set GHE_HOST variable to resolve the issue.

Parents, students, and employers often fuss about going to the best University or hiring employees from the top schools. There also has been a recent trend of parents trying to get their child to attend the best middle school and high school. Education is an important part of one’s life and the education one receives may impact their entire life. Going to the top schools usually implies having the best teachers, the best resources, and the best chances for success after graduation whether it be for high-level education, research, or career.
