I recently learned about the existence of Conway’s Game of Life and it fascinated me. It basically is a grid on which each cell can be either dead or alive and after one step or generation a simple set of rules apply:
- Any live cell with two or three live neighbors survives.
- Any dead cell with three live neighbors becomes a live cell.
- All other live cells die.
Many times I have spoken to friends about Bitcoin and the blockchain to try to explain why it is so revolutionary as a concept. It is for some people a complex topic to understand so I decided to write this little article explaining it a bit and expressing my general opinion on the matter.
Some time ago I read that many people are storing their cryptocurrency balances on apps and this is not good from a privacy point. These apps are very convenient but have the downside that when you store your balances, this information in synced to online servers for your convenience. However, the crypto world is quickly expanding and some of those sites are not always very secure and can leak precious information. Ledger itself, being a very reputable hardware wallet manufacturer had a security breach which exposed thousands of their customer’s details: July 2020 Ledger leak. This information will then be potentially used for targeted attacks on crpytocurrency hodlers. This is why I decided to create my own anonymous cryptocurrency tracker tool.
Git is an immensly popular and useful tool among developers. There are also other version tracking systems such as SVN, which you will need to work with if you plan to upload an opensource plugin to wordpress.org. I personally don’t like SVN too much and that is why I looked up how to automate code delivery to SVN from within Github Actions. This could also be done easily with any other automation service but I decided to give Github Actions a try.
For this experiment I wanted to automate a Wordpress website installation using GIT into my Gandi Simple Hosting instance. Along the way I came across several roadblocks which led me to using GitLab CI/CD which I had been wanting to try for some time so I thought this was a good exercise for my curiosity and below I describe how I got it working.
This website has been online for quite some time as a WordPress blog. I know WordPress very well but never really put much time into maintaining a website of my own. I decided that I wanted to update the site to a different platform and make it as minimalistic as possible so I decided to give Jekyll a try.
Since the very beginning at my University training I have been intensively using Wolfram Mathematica. It is a fundamental tool for solving any high level mathematical problem and a powerful tool for visualization. Among other many powerful features, are the demonstrations, where you can create interactive renderings as shown in the examples below.
I am writing this post as I have spend most of the day trying to setup Mavericks Mail to work with Gmail properly. I have been using OSX with Gmail for a long time now, but recently I noticed Mail.app on my MacBook Air was consuming too much CPU at times and my iMac was getting unresponsive too as I could hear the hard disk constantly spinning. I noticed after some time that it happened while syncing with gmail servers.
I have worked on all three major platforms, Windows, then Linux for some years and finally Mac. I do on my mac my daily coding and wanted to list the software on which I rely daily.
If you are new to web development, I usually recommend tizag.gom which is where I started learning most of my php skills.
I hope this list is useful to any fellow coders newcomers to the Mac
