Signal for encrypted instant messaging


Signal is an encrypted instant messaging and voice calling application for Android and iOS. It uses the internet to send one-to-one and group messages. You can include images, videos, as well as make voice calls.
You should use this for your group, text, picture, and video messages. This means that you would use Signal instead of the default messaging apps on your phone.
Encryption is important in your messaging as it secures your information using a protocol called TextSecure that allows users to communicate using voice and text without your information being intercepted.
Unlike many other text messaging products, Signal’s code is open source. That means that experts can regularly inspect and audit the code to ensure that something isn’t happening behind the scenes with your data.

Install Signal on your devices

To get started, follow the Android or iOS guide from the EFF. I also recommend using the Chrome app to message from your browser.
When you install Signal, it will verify your phone number by sending a text message to your device. It will then generate encryption keys for your account. These encryption keys are like an electronic handshake between devices as you chat.

These 7 Common Speaking Habits Undercut Your Credibility (Fast Company)

These simple behaviors are easy to fall into when you’re nervous, but they can make listeners think twice about taking you seriously.

Your credibility as speaker always hinges on what you’re saying, but it also has a lot to do with how you say it. When you’re nervous, these common bad habits are easy to miss, but paying a little more attention to how you look and sound can help you come across as someone really worth listening to.

  • Oversmiling
  • Too much energy
  • Winking
  • Rapid Pacing
  • Fidgeting
  • Stoic Delivery
  • Variable pitch

I’ve found that pacing can sometimes be a challenge in my public speaking. I try to focus on rooting my feet in a spot, and consciously not moving.

Live an antifragile way of life

Doug Belshaw shared this excellent post from Buster Benson on Living Like a Hydra. I recommend reading the whole post…multiple times. You won’t regret it.
One of the things I really enjoyed from the piece was this list of 10 ways to live an antifragile life:
  1. Stick to simple rules
  2. Build in redundancy and layers (no single point of failure)
  3. Resist the urge to suppress randomness
  4. Make sure that you have your soul in the game
  5. Experiment and tinker — take lots of small risks
  6. Avoid risks that, if lost, would wipe you out completely
  7. Don’t get consumed by data
  8. Keep your options open
  9. Focus more on avoiding things that don’t work than trying to find out what does work
  10. Respect the old — look for habits and rules that have been around for a long time
