Fast Tip #2 – Restart apache without interrupt the current requests(threads) [linux]



Sometimes we need to restart the web server apache in order to reload the new settings, for example, you added some new host config. But we don’t want that the current requests be lost, and we then don’t want that this reload of settings cause problems for the users.

Debian/Ubuntu/Mint:

Reload the settings using the command service

$ sudo service apache2 reload

RedHat/Centos/Fedora:

Reload the settings using the command service

$ sudo service httpd reload

For ALL distributions:

Reload the settings using the command apachectl

$ sudo apachectl -k graceful

Lifeproject, the beginning!



I was in the search of a strategic planning software of life, financial control, organization (gtd), etc. In other words a software that manages the various areas of a person’s life.

Given the situation, I wouldn’t find something that fits perfectly in my needs, then I decided to create my first software that would use a free software license (open source), I am going to be releasing the software  under the GPLv2,  I also took advantage of the fact of being in the process of learning and fixing a new programming language as well as its main framework  (ruby on rails), for me you really learn something when you create some product with that that you have learnt, from my process of learnt  the rails I am creating the  LifeProject, that is my way of thank to the free software community , creating another free software, that way all of us win.

The software uses only open source resources, database PostgreSQL (I’ve not tested with other databases),  the template AdmiLTE, and as said before it is written upon the framework Ruby on Rails.

The software will manage various areas. But I will start the development from the area that I will call “Culture”. According to a quote that I like very much from Leandro Flores “A people without art and without culture is a people that does not exist”. In other words, culture is the basis of the human being, there you can take some things like art, movies, books or anything else you want to learn and then grow as a person.

The other areas that I intend to initially include besides culture are finances and goals (short, medium, long term and of life), within goals we can include projects, habits, etc.

Installing Gogs(git), Nginx, MariaDB on Linux Ubuntu/Mint



The Microsoft bought the GitHub for US$ 7,5 Billions, and the  internet got wild, you can continue using the GitHub,  according to Microsoft, it will keep github as it is.

There are several alternatives as GitLab and the BitBucket, also there are options that are free source/open source that you can install there in your server. The GitLab has a Community version, it is written in Ruby and has a lot of resources, because it has many resources it demands at least a computer with the minimum of  4 GB of memory Ram, to old modests servers we have available the Gogs written in Golang, it is simple but it meets all our basic needs to whom uses the GitHub and it can be installed there in your old computer with 512 MB of memory Ram.

My history with the free software world



My history with the free software (as in freedom), has long date. I’ve begun to try to use when I was in the college, about 2006, I didn’t begin by encourage of my University, but I began because a friend of college encouraged me. I think that is a mistake courses in the area of technology don’t encourage to use free software, because free software gives more liberty and possibilities for who is learning to program. But coming back to my experience, I’ve tried to begin in one distribution for expert users in Linux, the Slackware, but as soon as I began, I gave up, due the difficult to found drivers to a modem of mine. I also had to compile the majority of the programs for this distribution. My Internet in that time was through a dial up modem 56k and I used only on the weekends because on the weekends was cheaper than Monday to Friday. After that I changed to Kurumin, a Brazilian distribution based on Kinnopix who already had Continue reading…

Why did I start a blog?



Why did i start a blog? Then this question shows up in my mind, and the main reasons that I see be these:

  • Practicing writing;
  • Practicing English (that I am learning);
  • Sharing knowledge in the areas that I love, mainly technology/software development/free software(open source);
  • Making new connections and friends;
  • And last, but not less important, sharing experiences of life.

And as every begin in something new, I imagine that my texts will not be the best, but I hope that I evolve and improve with the time.

I also see that, as a look through a time machine that can see past’s flashs, and then appreciate the evolution.
