# gpgedit lets you edit a gpg-encrypted file without much fuzz -- similar to
# sudoedit.
#
# For this to achieve, gpgedit uses gpg to decrypt your file and save the
# plain text in a temporary file under /dev/shm (tmpfs) which will open in
# an editor. After the changes have been saved and the editor closed your
# plain text will be encrypted and written to the original file.

The heart of software

• Leaders within a team who understand the centrality of the domain can put their software project back on course.
• Software developer is like a researche, both have the responsability to tackle the messiness of the real world through complicated domain that has never been formalized.
• There are systematic ways of thinking that developers can employ to search for insight and produce effective models.

One. Crunching Knowledge

Ingredients of effective modeling

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

Slack Tweaks

In Fall 2023, Slack introduced an updated client with some unpopular UI changes. The tweaks in this document can be used to revert to the old client or hide the new side bar. These will reset every time you fully close Slack but they are easy to re-apply once you get the hang of it.

The fist step is to enable dev mode, which can be accomplished by setting a system-wide environment variable.

(Mac OS) Enable Dev Mode

1. Close the Slack app (command + Q)
2. Open the terminal and run these two commands separately:

Get a DDNS up and running with DuckDNS - Step by Step

DDNS? What is that?

A dynamic DNS. DNS stands for Domain Name Server, which, in other words, is basically the server that answer your queries when you search for a hostname on the internet.

Example: If you search for "google.com" there will always (probably) a server that points out to that hostname and tells you the information the computer needs; the IP address.

If you want to give it a test, you only have to open your terminal and type "ping google.com" and you will see the real IP address appear! In my case it's 216.58.201.174 .

Anyways.. A DDNS is useful if you want to link or put a hostname to an IP that is not STATIC.
