Many programming languages, including Ruby, have native boolean (true and false) data types. In Ruby they're called true
and false
. In Python, for example, they're written as True
and False
. But oftentimes we want to use a non-boolean value (integers, strings, arrays, etc.) in a boolean context (if statement, &&, ||, etc.).
This outlines how this works in Ruby, with some basic examples from Python and JavaScript, too. The idea is much more general than any of these specific languages, though. It's really a question of how the people designing a programming language wants booleans and conditionals to work.

Let's say you receive an app (e.g. MyApp.ipa) from another developer, and you want to be able to install and run it on your devices (by using ideviceinstaller, for example).
Or your certificates and provision profiles have expired and you want to provide a new build to your clients without having to make a new build on the latest XCode or iOS SDK.
The first step is to attain a Provisioning Profile which includes all of the devices you wish to install and run on. Ensure that the profile contains a certificate that you have installed in your Keychain Access (e.g. iPhone Developer: Some Body (XXXXXXXXXX) ). Download the profile (MyProfile.mobileprovision) so you can replace the profile embedded in the app.
GitHub allows automated builds using GitHub Actions. A commonly asked question is how to release artifacts (packaged Java jars) built by Maven and Gradle to The Central Repository. The GitHub Actions documentation provides only part of the answer.
So, first, configure your Maven project for staging artifacts to The Central Repository, by reading through Configuring Your Project for Deployment and following those steps. Please make sure that the maven-gpg-plugin is configured to prevent gpg
from using PIN entry programs, as follows:
<configuration>
<gpgArguments>
<arg>--pinentry-mode</arg>

Before Github supported SSL encryption for github pages sites, many people were using CloudFlare (CF) as their DNS provider and CDN proxy. CF allowed users to enable SSL encryption from the CDN end points/proxies to the end user. This was great and it allowed visitors to your website to connect with a secure connection between their browser and the cloudflare CDN box that was serving your content. However, with this setup one (significant) link in the chain remained unencrypted and

Windows is really horrible system for developers and especially for devops. It doesn’t even have a usable terminal and shell, so working with command line is really pain in the ass. If you really don’t want to switch to any usable system (OS X, Linux, BSD…), then this guide should help you to setup somewhat reasonable environment – usable terminal, proper shell, ssh client, git and Sublime Text as a default editor for shell.
