+In this talk we will talk about privacy and security issues of using centralized social media platforms and proprietary software.
+I will talk about the network effect, the fact that social networks (and use of other software) are more useful if more people use it. It is necessary to grow the number of users of these technologies before any individual can enjoy the benefits of this software.
+We, as an open source community, need to actively organize people to collectively start using decentralized and free and open source software. Creating local groups (hackerspaces) and events that will bring people together and use decentralized applications as main means of communication is the easiest way to give the users an immediate benefit of using these technologies.
+I will mention some decentralized apps like Matrix,XMPP and Mastodon, and emphasize the importance of installing these apps even if we don't need to immediately have use for them.

+Digital privacy and cyber security is often presented as individual issues that we can solve on our own. In this talk we will talk about necessity of fixing these problems collectively and required steps we need to take. We don't need to switch to more secure ways of communicating right away, but we need to use secure alternatives in addition to insecure technologies in order to allow others to make a switch.

+# Intro
+
+The fundamental problem:
+
+```bash
+git submodule update --init soundscape
+cargo build --release
+install -pm755 target/release/tap /usr/local/bin/
+```
+
+*But you can't type this for each run.*

+
+## First Solution
+
+```bash
+#!/bin/sh
+git submodule update --init soundscape
+cargo build --release
+install -pm755 target/release/tap /usr/local/bin/
+```
+
+At this point, every test takes 10 minutes.
+
+## Second Solution
+
+```bash
+#!/bin/sh
+[ -f soundscape/.git ] || git submodule update --init soundscape
+[ -f target/release/tap ] || cargo build --release
+[ -f target/release/tap ] || \
+    install -pm755 target/release/tap /usr/local/bin/
