Last week, I received an email from Google stating that my email and password had been leaked in a recent data breach. Like many people, I’m guilty of reusing the same password for multiple accounts, so the leak had compromised my information in a number of different locations. I was advised to change all of my passwords and to use different passwords for each of my important accounts.
As part of my exploration of a minimum set of devops tools, I’ve been learning how to stack containers full of Rails apps onto the Docker. There are plenty of examples of how to get started with Rails and Postgres on Docker, even one from the whale’s mouth, as it were. Working from this example, it was pretty clear to me that one of Docker’s major strengths is that it makes it really, really easy to get something running with a minimum of fuss; it took all of about a half day to learn enough Docker to hoist anchor, and even tweak a few things to my liking. One thing kept nagging me about the Docker example, though, and that was a warning from bundler when running docker-compose.
Modern cryptography is a very murky subject for many people, so today I will try to explain to you one of the more complex subjects, Elliptic Curves. Many of you may have heard their name before, but likely don’t know much about them beyond that. To begin, I will describe what an elliptic curve is.
While going through a set of configurations to connect on a remote machine I was asked to upload my public key and I realized that I didn’t really know what that was for. If you are asking yourself the same question, or need to convince your mom she can safely use her credit card online, here is brief summary of what’s going on behind the curtains.
When it comes to developing an Android app that deals with sensitive information, you must take extra precautions to make sure that the information doesn’t fall into the wrong hands. Although Android devices come with state-of-the-art security features, app developers often don’t leverage them. Even if they do, they may not necessarily be using them properly. One simple security hole is all it takes to compromise your app’s security as well as the security of the servers/systems it’s connecting to.
