I decided to migrate a few virtual machines from one hosting service to another. Most other howtos either recommend a reinstall or need access to the hypervisor (KVM/libvirt in this case – I could use native migrate functionality), which I did not have. Of course, you need to make sure you have the same architecture […]

How to use cryptocurrencies for discounted shopping on Amazon
Many people ask me how a “normal” person can use cryptocurrencies for something, that is not possible without them. One of such uses is using a service called purse.io to shop for almost anything on Amazon using cryptocurrencies while getting up to 33% discount. So daily shopping for less, yay! I made a video howto […]

The wonderful host of Slovak Radio International Jonathan McCormick interviewed me about cryptocurrencies. Enjoy!
Solution to crony capitalism?
When I first heard about a new episode of Econtalk with Michael Munger (and the Econtalk host Russ Roberts), I didn’t pay attention to the title, I just new it has to be great as all of their conversations. I had a chance to see Michael Munger live at SREK – Seminar of Austrian economy […]
Sharing files using send.firefox.com
Sharing files has been an issue. There were several services for that, I mainly used transfer.sh and dropbox/google drive. Now that Mozilla Foundation launched send.firefox.com, I switched to it. It is not as easy as transfer from the command-line by itself (you cannot upload files through curl for example like with transfer.sh), but there are […]
Front-running on content platforms with market – case study of yours.org front-running bot (part 2)
In previous part, I shared what is interesting about content sharing networks that incorporate direct market mechanisms such as upvoting, tipping, paid comments and paid content (paywall). In this part, I will focus on upvoting, because it allows people other than content creators to discover and invest in great content and make money if they […]
Paid content networks – how to get rewarded for creating content, a case study of yours.org (part 1)
One of the main problems that many people have with the Internet is that is free. Of course we all love free stuff, but is it really free? No, we just don’t pay for it, because advertisers do. The problem is that people create useful content that is then used to attract attention of other […]
Even more privacy with DNS over TLS
In my previous post I described how to increase your privacy using DNScrypt and cloudflare’s DNS over TLS service. I was finally able to deploy this easily without hacking on Turris Omnia’s OpenWRT and test if it is working correctly. It’s not rocket science, you just need to make sure you have the latest OpenWRT […]
Attack on crypto attack has begun… and it is not what you think
The attacks on crypto by banks and states have begun – and they might not even be aware of it. It’s emergent behavior. Let’s see what happened. First some background. The European Union’s proposed 5th Anti Money Laundering Directive concerns virtual currencies and anonymity directly. Here is a helpful factsheet showing the main changes. This […]
Patents in crypto – not a way to go
Cryptocurrencies are usually open-source and it’s by design. They would be less trustworthy if they were not. It is essential for the nodes to be open-source, for multiple implementations to be viable. These implementations can independently verify the validity of rules. There is one “backdoor” to open-source and that is (software) patents. Some countries do […]
