Scientists make it very clear that Coronavirus were not created in a Laboratory. When a new virus is synthesized, a genetic footprint is left. So it isn`t hard to analyse whether the virus was created by humans or not.
If you were the person or group responsible for creating and spreading a new virus or biological weapon, would you do it in a way that allow other people to track it back to you?
A terrorist group WANT to be found. So it is not a problem for ISIS, for example, to leave the genetic annotation in the virus. …
Last week I went to Porto Alegre to attend the BrazilJS Conf 2018. It was an outstanding experience where I could learn a lot about the technologies I work with everyday.
This travel was sponsored the company I work for (Oi) as a way to train and qualify its employees.
Finding a welcoming place to work, where you are free to be creative and challenge yourself everyday is certainly one of the most important things to become a better developer.
I can’t see myself working in a place where I feel oppressed or restrained. Before choosing a new place to work always try to know about the culture, ambience and hierarchy of this company better.

I have been playing soccer video games for over 20 years. I probably started with Sega Worldwide Soccer 97 for Sega Saturn, or maybe International Superstar Soccer for SNES. I spent days playing the Fifa series, since Fifa 98 for Nintendo 64 and I can still hear that amazing cinematic opening of Fifa 2002 with Gorillaz’s 19–2000 in my mind.
Assuming 5 levels of difficulty, I play 3 or 4, depending on my mood. I’m usually one of the best players among my friends when we get together.
I spent some years playing on PC only, but last year I…
Well a few months ago I was working on an application that was meant to be deployed with Docker and connect to services also running on Docker. This application was a API built with Node.js and one of the services it connected to was MongoDB. I was using Docker Compose to orchestrate this environment.
It shouldn’t be a problem. Everything was working fine until I had to install it on production server and show it to the client. I had a very tough moment to discover why my Node.js application couldn’t connect to the database. …
Let’s say you just downloaded a tar.gz file, extracted the contents to a folder and now you’re running the application using its executable.
The first thing you can do is to create an alias to this executable. Open .bashrc file by running in Terminal:
Add a line to this file like the following
alias mynewcmd=’<Path to the executable>’
Save and close the file. Reload it by running:
source ~/.bashrc and now you can execute the application by running
But you still can’t create shortcut icons, pin it to the Favorites bar, chance the shortcut. To create…
There is a package manager for Windows called Chocolatey. To install it, you run a simple command line and in a few seconds you are good to go.
Make sure you are running the command shell as an administrator. Choose the correct command to your case and when it finishes downloading and installing, run the
choco command to check if everything went well.
Installing Node.js or Git is as simple as running another command line. You can get a list of available packages here. Check the number of downloads to pick the best choice for what you need. See an…
sort, you probably noticed that something weird happened with the result.
Let’s take the following array of integers as an example:
This will return the array
[1,2,3]. Everything looks fine so far. You just successfully put all the numbers of this array in a crescent order.
The problem occurs when different numbers have the same first digit.
This will generate the array
[1,10000,2,3]And that’s the ultimate definition of “weird”. Things get much worse when you add negative numbers.
