Diary of a Devman

Retrospective feelings...

Such a wild dream, isn't it?

Intro to Reality During the COVID-19 pandemic, I worked with an experienced Engineer.

The 4th highest mountain peak (4680m) in Mexico, Xinantecatl (The Naked Lord), often called "Nevado de Toluca".

Yesterday, I was in a event, talking about Transactions, ACID, Isolation phaenomena, etc., under Postgresql.

I just want to have a Docker Image of Postgresql on Docker Hub, with preloaded data saved, so I can pull it and create a container whenever I want, even sharing the image with other people for testing general stuff (just as a code repo on Github).

The airplane was invited to transport people.

On the last 24hs, I helped different people, in a variety of ways.

Seems like yesterday...

Sometimes it's on our side, specially when we are young, yet sometimes it could be against our will.

One may find her/himself creating scripts with initial and final instances of datetime.now(), executing a block of code in between them and then obtaining a delta between the two timestamps, in order to understand how long the code will take for its execu…

Over the years, developing software, I sometimes wonder how much do I know about OOP.

I'd generally just search some directory inside /var, which might be quite obvious, but nothing will be better than reviewing the configuration that Postgresql is considering for its internal management.

I remember doing this (setting up SSH key pair access) like a ninja, without ServerFault or anything else.

Fantastic Vulnerabilities and Where To Find Them You might already heard about CVE or Common Vulnerabilities or Exposures, which is an initiative sponsored by DHS (Department of Homeland and Security) and CISA (Cybersecurity and Infrastructure Security Ag…

It's always a good time, to open up a terminal and expressing calculations through code, just as any scientist would do, with the exception that I'm no scientist (at all), although I kind love Computer Science.

It's being a while that I work with Docker, and some commands are on top of my head, some don't.

Generally, we all iterate through a variety of objects in Python, like: Tuples Lists Dictionaries Strings Sets But besides theses objects, you can create your own iterable object!

On my first steps as Software Developer, I used to develop my own implementations of JSON validation, which worked great, but some JSONs were complex to validate, increasing complexity on improving the custom validators, becaming difficult to keep up these

Diary Note turns into Article It was supposed to be something short, but it became an article, since that the topic could be quite extensive.

A code that fails and no further information is provided, is a situation of despair: no Traceback, no nothing.
