You could have just called this article "The FSF: An idea whose time has passed".

There are a number of things you wrote that just make absolutely no sense. Whether you want to admit it or not every single internet company used free and open-source software. From the Nginx and Apache servers to the OS level services they run on. You may say that this is "industrial" open source software but the result is the exact same. A tool or service I can independently verify and freely use. The only distinction being a licence.

You talked a lot about security…

Step by step guide

Many people spend time choosing internet browsers and other tools that are very privacy-focused. However, not only does your phone contain more privacy-invading tools and services than your computer but you also carry it around with you all day. There are ways to harden your Android phone but the best thing to do is install a custom ROM that is open-source and doesn’t contain any of the spyware that Android does.

What is CalyxOS?

The most popular custom ROM out there at the moment is LineageOS. Not only can it be installed on nearly any android phone but it…

Although I do appreciate the attitude in the article there are a number of pretty crucial issues with bitcoin specifically (cost of mining, time it takes to authenticate transactions, not being anonymous etc..) that I've discussed in a recent article. I do think your view on what Bitcoin represents is spot on but the issues in the crypto space seriously need to be addressed.

The future foretold by blockchain has a long way to be actualised

The world we currently live in has had a significant trend towards centralised power. Despite technological advancements, this trend has not changed and, in many ways, has accelerated. Nearly everything we do, from paying for goods and services to communicating with each other to the food we consume, is reliant on a few very large companies and organisations. Although the idea of centralised services may seem like it has brought stability or security, reality has shown that this is not the case. Creating a single point of failure and allowing organisations unchecked power has had untold consequences. …

It’s been a week since Trump got kicked of Twitter and Parler got kicked off AWS. Deplatforming has become a hot topic which has made some people question the future of social media. For most people this isn’t a huge concern as they don’t discuss controversial topics but like every other aspect in life it’s good to look for alternatives that don’t make you more reliant on giant corporations. The answer to most of the problems with social media…

Mastodon is a decentralised social media platform that you can host yourself

The topic of de-platforming has been discussed a lot lately between Trump getting booted off Twitter and Parler getting kicked off AWS. With most major social media sites cracking down on certain users, people have searched for alternatives. Unfortunately, some of the alternatives have gathered a less than desirable reputation for their user base. In this, I’m going to explain how you can automatically set up mastodon on your server with an Ansible script.


Mastodon is a social media site unlike any other. Instead of accessing a website running on some data…

Setting up your SSH config and Fail2Ban to automatically jail hacker IP addresses.

In a previous article I discussed how you can host a range of cloud services on your own private server. In this article I’m gonna discuss how you can secure your server a bit more using Fail2Ban and by configuring your SSH for top security.

Unlike a traditional password captcha, SSH doesn’t by default restrict the amount of times you can guess a password. This means hackers trying to access your server can use a brute-force attack to become the root user…

In the wise words of the former head of the NSA “We kill people based on Metadata”.

Whenever you go to take a picture or write a document there’s a range of hidden data that isn’t seen on first glance. Details such as the date the picture was taken, location it was taken, type of camera used and encoding format is all included in an image’s metadata. You may say that this is inherently harmless but this data is just another way for the sites we use (and the people viewing our content) to gather…

Host your own services instead of being reliant on giant tech companies

Video Explaining/Showing the steps

These days people are becoming more and more reliant on online services. The technology that was created to allow us to communicate with each other and share memories has, in many ways, made us more distant and less able to modify/change the tools we use. It also comes at the price of giving up our data to large corporations to the point where they often know more about us than we know about ourselves.

Instead of using Gmail, dropbox, or any of the other supposed free services, you can host free open-source services that are privacy-respecting…

Building an app on AWS to help save energy bills and the environment

Video explaining further

The idea behind this article came to me a while back. While writing a previous Medium article about predicting energy demand I thought of the idea to build an app that would notify users when electricity prices are high. Originally this was an addition to the previous application but I quickly realized that regular people would get more benefit out of it.

The app itself is explained a bit further in the video above but to summarize it will gather real-time electricity prices and notify users when the price rises in their location. This allows people who…
