I decided to build out my “automated” SEO agency, myseosucks.com. It’s been quite the rollercoaster ride but super exciting to see when clients / agencies on-board themselves and can self-manage the SEO process.

I wrote a book about blockchain programming: https://www.packtpub.com/big-data-and-business-intelligence/...

I didn't get rich by writing this book, but it's very useful for networking in blockchain community. It's like an expensive name card. It also boasts my reputation.

I developed a blockchain framework called Mamba: https://mamba.black

For those who are familiar with blockchain programming, Mamba is like Truffle but instead of based on Solidity+JavaScript, it is based on Vyper+Python.

For those who are unfamiliar, Mamba is like Ruby on Rails but it's for writing decentralized / programmable money applications.

My plan for 2020 is to write more tutorial articles in Mamba website and develop more features in Mamba framework.

For business: I am helping a company build their programming bootcamp (not related with blockchain).

A peer to peer file system sharing application with GUI in browser

Can you share which tool are you working on. Would love to evaluate it up. P2P things just interests me.

https://github.com/prettydiff/share-file-systems/

I would love to get some feedback.

Some notes:

* Currently it uses IP addresses for connection, which is less than ideal.

* Currently every device is treated as a separate user.

Road map:

* I am working on a web service that will issue named accounts and digital certificates. The named accounts will identify their current IPv6 address to the account service so users need only to connect to an account which can be any IPv6 address for portability.

* Once accounts are a thing I will need to change several things on the client application. My goal in this step is to separate users from devices so that a single user can connect and manage multiple devices. That extra layer of abstraction will allow options for management, security, and convenience that are not currently available.

* I also want to enable end to end encryption for all users/devices. That is just a simple matter of public key exchange built into the already designed invitation model.

* Then I want to create a text client that supports markdown.

A way to visually compare how sites load inside vs. outside China https://www.chinafy.com/tools/visual-speed-test !

This tool was built as part of a larger suite of tools that highlight and resolve the cost performance gaps businesses face when entering the Chinese market.

SIXTEENmm (https://sixteenmm.org), a streaming site for old, hard to find and indie films.

I've spent most of the year working on colourisation and recovery techniques. Colourisation is probably 70% of the way, but restoration is as hard as ever.

The project isn't meant to be a unicorn. The tech stack is boring, and probably wouldn't scale.

There's about 50 people on board, and about two or three videos streamed a day - so it isn't remotely "successful" yet, but I set a four year timeline for it.

I don't have any specific stats to offer - because I don't collect it. I collect as little data as I can get away with. Both for personal belief, and economic reasons.

Hard to get massive fines for the inevitable breach when there's no PII to steal.
