SHA2017: hacker conference/camp videos are up

SHA2017 is on today (it started over the weekend and ends tomorrow) and it is a hacker conference and camp.

Most of the conference videos are up on Youtube and they are very informative and fun. There are a lot of good talks. I’ve picked a few to showcase here but you should check out the whole playlist of SHA2017 videos.

Decentralize! Self-hosting in your own home using Sovereign

In the Decentralize! talk, the software Sovereign is explored and shown to be a good way to set up your own personal cloud and host your own services and data. Sovereign is a set of playbooks that can be run to install the software on a server that you run. It’s similar to the Freedom Box project.

The software you can self-host with Sovereign is:

  • Dovecot, Postfix and Roundcube for email servers and a webmail interface
  • Jabber/XMPP messaging server with Prosody
  • RSS reader
  • VPN server with OpenVPN (FreedomBox also can do this)
  • Git code repository hosting

Bitcoin, cypherpunks, a thoughtful perspective on the future

Bitcoin, cypherpunks, a thoughtful perspective on the future

Thought-provoking article in Bitcoin Magazine about a conference that happened at the end of September, the Hackers Congress Paralelni Polis in Prague.

It’s an interview with two crypto-anarchists who explain their views on the direction of society and the possibilities of a future that includes mainstream usage of Bitcoin and encryption technologies.

One of the first questions asked by the interviewer is, “what is cryptoanarchy?”

This is their answer:

Sip: Simply put, crypto-anarchy is the idea that people can govern and organize themselves without governments, by using the tools of cryptography, cryptocurrencies and other means of decentralization.

Lupták: With these tools, we can build a more effective, a more free and a more voluntary society…

This is a nifty idea, and what makes it nifty is that free software and open source developers have been collaborating for decades and have been more effective, more free and all open source developers are contributing voluntarily.

In fact, there was a recent article by Daniel Pink suggesting that the further we are from a problem, the more creatively we will think about it. In open source development, we are close to the problem but when reviewing other people’s code or submitting patches, we are further away from the problem meaning we can be more creative in coming up with solutions.

So at least for software development, a decentralized model can work. Can it work as a replacement for government? That question is still open but we have seen lots of actions to make government more transparent and more accountable to the people. If you’re looking for small-scale examples of “anarchy” in action, you can look at the Workplace Anarchy described by someone who works at Igalia, a software co-operative that sells consulting service and is quite profitable.

In the interview they mention OpenBazaar which is free/open source software that lets you run a peer2peer ecommerce site. The idea there is to reduce transaction costs to whatever the bitcoin transaction costs are and to remove any middlemen that would cut into profits. A thoroughly free-market-oriented concept that is based on market efficiency and accomplished through free/open source software with the BitCoin currency.

Copay – a shared bitcoin wallet

Copay – a shared bitcoin wallet

Copay is a Bitcoin wallet that distinguishes itself from other wallets by allowing multiple users to be part of an account. This means that friends and coworkers can use the same wallet and a transaction will not be approved until a certain number of participants (or all of them) have approved it. This is great for spending shared budgets like for conferences.

It’s also great for managing your Bitcoins which can then be donated to various free/open source projects.
