Building GNU Emacs from sources – Znpy

https://znpy.wordpress.com/2016/07/08/building-gnu-emacs-from-sources

Thoughs, notes and ideas. Building GNU Emacs from sources. I want to look at the GNU Emacs source code because I have some ideas I want to try and implement. If you want to write patches for an open-source project, the first thing to do is to check out the latest version from the repository, make sure it compiles and runs. At this stage, you also want to make sure that all of the tests passes, so that you can start working on a verified assumption that you branched from a fully working commit. On my mach...

I wrote a toy url shortener and people started using it – Znpy

https://znpy.wordpress.com/2016/06/02/i-wrote-a-toy-url-shortener-and-people-started-using-it

In my talk I shown how to go from zero to a fully functional application with a small but functional deployment environment based on Dokku. The nice thing I noticed is that people started using it, and now I have some URLs shortened through my system. And you can find the source code on Gitlab. Testing Go applic...

Learn how to use GNU info – Znpy

https://znpy.wordpress.com/2016/12/08/learn-how-to-use-gnu-info

Thoughs, notes and ideas. Learn how to use GNU info. Recently I’ve been digging a lot into GNU/Linux system administration and as part of this, I have finally taken some time to google about that mysterious info command that has been sitting here in my GNU/Linux systems, unused for years. Well, I can tell you, it has been a life-changing experience. Texinfo-based documentation is awesome. First, some terminology. Info: the command-line tool you use to read documents written using the texinfo format.

Some notes on bash shell programming – Znpy

https://znpy.wordpress.com/2016/11/19/some-notes-on-bash-shell-programming

Thoughs, notes and ideas. Some notes on bash shell programming. I recently began working as a GNU/Linux System Engineer at a software company. My job involves answering to tickets from customers, and take action in the case of blocking issues. In doing all this, I am reading a lot of bash scripts, and I am also deepening my knowledge of the Bash shell as a programming environment. Common sense: avoid side effects. This is a good way to do it:. User@host $ truncate -s 0 $FILENAME. Despite what I have said...
