Hi all, as part of my goals for 2018, I decided to watch a few movies on my list that are not related to the Science Fiction category.

The selection of the movies are based on classics or claimed as good by the critics.

My intention with this exercise of watching things out my comfort zone is to amplify my vision of the world, storytelling, and references.

This text does not contains spoilers.

To start the year I choose Whiplash.

Plot: A promising young drummer enrolls at a cut-throat music conservatory where his dreams of greatness are mentored by an…

Hi everyone, here is tip to fix this Wordpress issue.

NOTE: This is a procedure that will works only if you have administration permission.

The cause of the problem is: Your folder doesn't have the same owner of the PHP process / Apache.

So lets go, step-by-step (uuuhhh babyyyyy!!!)

1 — Connect to you server using the terminal
2 — RUN the ps aux | grep php

3 — Check out the first line of the result. If it's different from the second line, we are good to go to the next step;
4 — Time to change your site folder…

Hi guys a new tip about how to solve the following warning:

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = (unset),
LC_ALL = (unset),
LC_CTYPE = “UTF-8”,
LANG = “en_US.UTF-8”

Every time that this type of warning appears its because some of the environment variable are unset.

Note that in my example, LANGUAGE and LC_ALL are equal to (unset).

To solve that problem, just set / export the variable with your system language. In my case: en_US.UTF-8.

Command:

export <VARIABLE≥=<VALUE>

Command with values

export LANGUAGE="en_US.UTF-8"

Hi everybody, this is a simple snippet to help you convert your JSON file to a CSV file using a Python script.

Create a new Python file like: json_to_csv.py

Add this code:

import csv, json, sys
#if you are not using utf-8 files, remove the next line
sys.setdefaultencoding("UTF-8") #set the encode to utf8
#check if you pass the input file and output file
if sys.argv[1] is not None and sys.argv[2] is not None:    fileInput = sys.argv[1]
    fileOutput = sys.argv[2]    inputFile = open(fileInput) #open json file
    outputFile = open(fileOutput, 'w') #load csv file
    data = json.load(inputFile) #load json content
    inputFile.close() …

Hi, here is a quick tip about a really annoying problem when you install MongoDB over Ubuntu 16.04 distro at AWS LightSail.

When you start your MongoDB through:

sudo service mongod start

And the result is something like this:

● mongod.service — High-performance, schema-free document-oriented database Loaded: loaded (/lib/systemd/system/mongod.service; disabled; vendor preset: enabled) Active: failed (Result: exit-code) since Wed 2016–12–07 03:43:00 UTC; 3min 9s ago Docs: https://docs.mongodb.org/manual Process: 24453 ExecStart=/usr/bin/mongod — quiet — config /etc/mongod.conf (code=exited, status=14) Main PID: 24453 (code=exited, status=14)

And you don't know why.

The problem is, the Mongodb SOCK do not belong to the mongodb group…

Once in a while, when you try to connect to the database using a code like PHP, Python or even with a MySQL cliente like SequelPRO an error message will popup for you:

Your password has expired. To log in you must change it using a client that supports expired passwords.

You have different paths to solve this situation and here is a simple one:

1 — Open your terminal
2 — Type: mysql -u root -p
3 — Type you old password
4 — Type: SET PASSWORD = PASSWORD(‘XXXXXX’); //REPLACE XXXXXX WITH YOUR NEW PASSOWRD
5 — Be Happy :)
