+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.

+- hash functions create unique data corresponding to each user password from which it can't be directly determined what the password was, but it can be checked if a specifc password hashes to that value
+- salted hashes are hash values that are stored with additional data which is added to the password before hashing it, makes each hash value unique, even if two passwords are the same

+- if the hash function is difficult to calculate for a specific password, it is more secure, since attackers need to spend more resources to check if a specificv password hashes to needed data

+# Zen Master Foo
+
+Master Foo once said to a visiting programmer: "There is more Unix-nature in one line of shell script than there is in ten thousand lines of C."
+
+The programmer, who was very proud of his mastery of C, said: "How can this be?
+C is the language in which the very kernel of Unix is implemented!"
+
+Master Foo replied: "That is so.
+Nevertheless, there is more Unix-nature in one line of shell script than there is in ten thousand lines of C."
+
+# 
+
+The programmer grew distressed. "But through the C language we experience the enlightenment of the Patriarch Ritchie! We become as one with the operating system and the machine, reaping matchless performance!"
+
+Master Foo replied: "All that you say is true.
+But there is still more Unix-nature in one line of shell script than there is in ten thousand lines of C."
+
+The programmer scoffed at Master Foo and rose to depart.
+But Master Foo nodded to his student Nubi, who wrote a line of shell script on a nearby whiteboard, and said: "Master programmer, consider this pipeline.
+Implemented in pure C, would it not span ten thousand lines?"
+
+# 
+
+The programmer muttered through his beard, contemplating what Nubi had written.
+Finally he agreed that it was so.
+
+"And how many hours would you require to implement and debug that C program?" asked Nubi.
+
+"Many," admitted the visiting programmer. "But only a fool would spend the time to do that when so many more worthy tasks await him."
+
+"And who better understands the Unix-nature?" Master Foo asked. "Is it he who writes the ten thousand lines, or he who,
+perceiving the emptiness of the task, gains merit by not coding?"
+
+Upon hearing this, the programmer was enlightened.
