Access to Bitbucket stopped to work via http and git

Yesterday I changed my Vivo Fibra plan to 100 Mb, so the company had to change the router. Everything was working fine until I needed to do a git pull, from my bitbucket repository. After tireless searches I found the solution. I still don't know if it has other solution, but this one worked to me. 

I just put it in the file /etc/hosts the line:

104.192.143.2 bitbucket.org

Now, try again to git pull or access bitbucket.org via browser. 

I hope this tip has helped you.

Infinite loop in npm install

To solve this error, run:

$ sudo npm -g --unsafe-perm install node-sass

Laravel - error on migrate

PHP 5.6
Mysql 5.5
Laravel 5.4


I had this error while executing: php artisan migrate

Syntax error or access violation: 1071 Specified key was too long; max key l ength is 767 bytes (SQL: alter table `users` add unique `users_email_unique`(`email`))

I solved by changing the file config/database.php:

'charset' => 'utf8mb4' by 'charset' => 'utf8'

'collation' => 'utf8mb4_unicode_ci' by 'collation' => 'utf8_unicode_ci'

Drop the created tables by laravel, and execute php artisan migrate again.

Mysql: errno 12

Message error: InnoDB: mmap(xxx bytes) failed; errno 12

To resolve the Mysql error 12, follow this steps:

$ sudo dd if=/dev/zero of=/swapfile bs=1M count=1024
$ sudo mkswap /swapfile 
$ sudo swapon /swapfile

Add this line to /etc/fstab
/swapfile swap swap defaults 0 0


This last step is needed if you would like to automatically enable swap file 
after each reboot.

Erro no pip

Hoje me deparei com o seguinte erro ao executar o pip:

$ sudo pip install <pacote>

Traceback (most recent call last):
  File "/usr/bin/pip", line 9, in <module>
    load_entry_point('pip==1.5.6', 'console_scripts', 'pip')()

ImportError: cannot import name IncompleteRead

Para resolver o problema, basta apenas atualizar o pip com o easy_install:

$ sudo easy_install --upgrade pip

Feito isso, o pip será atualizado e resolvido o problema.
