Hi, my name is Zackary Morelli. Welcome to my personal website. I am a physicist by education and .NET web developer by trade. This website serves as a personal blog and also as a test bed for me to experiment with web development and server management. Feel free to look around. Links to my Github and LinkedIn accounts can be found in the footer at the bottom of this page. You may email me at ztrm@ztrm.net. If you would like to send me an encrypted email, you may download my PGP public key or view it on keys.openpgp.org. For secure messaging, feel free to message me on Signal.

I'm currently looking for a new .NET Web development job. I'm open to other roles as well, such as IT helpdesk jobs. Feel free to take a look at my resume if interested.

In addition to running a few websites on an Ubuntu, Nginx, .NET stack, I also run my own email server stack (which is very difficult to do these days). My email above on the ztrm.net domain is run by this email server. Although not end-to-end encrypted, I think email is a very powerful and still relevant tool for communication due to its openness and ubiquity. Even though tools like SendGrid make it easy for applications to send programmatic emails via an API, I think real email servers are useful because applications can use them to send emails programmatically, but human beings can use the same email accounts to both receive and send emails using a custom domain name. For sensitive or private communications with people you know, I strongly recommend that everyone use Signal for encrypted communication. Signal is a free and open-source application owned by a nonprofit that supports end-to-end encrypted messaging, voice calls, and video calls.

ztrm.net is a static .NET 8 Razor Pages web app, using PostgreSQL as a DB. It runs on an Ubuntu server with Nginx as a reverse proxy web server. I use Cloudflare as a Domain Registrar, DNS Provider, HTTP/S traffic proxying service, and as a Web Application Firewall. Even though Cloudflare is a large for-profit tech company, they are genuinely privacy-focused and provide these services for free. Domain names they sell at cost, which means they only charge the ICANN fee for domain registration. I highly recommend Cloudflare's platform to anyone looking to host websites or email servers on their own. The extra level of security they provide is valuable in the extremely dangerous world of the modern internet.

More recently, I've been learning Blazor, specifically Blazor Server, for Single Page Application (SPA) web development. Instead of learning one of the major traditional JS SPA frameworks like Angular and React, as a C#/.NET developer, I chose to learn Blazor as an introduction to SPA development, and I am very impressed. Blazor is simply a superior way of doing web development for C# web developers. It is extremely powerful and flexible. Whether you are building a simple static website or a highly interactive website, Blazor simply makes web development easier than Razor Pages or MVC. Blazor vastly reduces the amount of JS needed to build a website, even a highly dynamic one. Blazor Server uses WebSockets and an efficient diffing engine to quickly update dynamic websites while keeping everything server-side. Blazor WebAssembly offers the exciting possibility to run a .NET web app as a true client-side SPA by running the app in WebAssembly on the client and then using API controllers to provide data services to the client-side app— all while avoiding the slow and interpreted nature of JS. I firmly believe all .NET web developers should be using Blazor, and I hope that the tyrannical dominance of Angular will lessen in the coming years to allow Blazor a more prominent spot in the web development world that it deserves.

Below are some other websites I've made and operate:
  • dallevamechanical.com - Simple .NET 8 Razor Pages web app I made for my cousin's HVAC company
  • morelliwebservices.com - Simple business page and status dashboard for various websites and email infrastructure that I run.

The Hydra Cluster of Galaxies

The Hydra Cluster of Galaxies

Within our own Milky Way galaxy, two bright, spiky stars stand like sentinels in the foreground of this cosmic snapshot. Far beyond them are the galaxies of the Hydra Cluster. In fact, while the spiky foreground stars are hundreds of light-years distant, the Hydra Cluster galaxies are well over 100 million light-years away. Three large galaxies near the cluster center, two yellow ellipticals (NGC 3311, NGC 3309) and one prominent blue spiral (NGC 3312), are the dominant galaxies, each about 150,000 light-years in diameter. An intriguing overlapping galaxy pair cataloged as NGC 3314 lies above and left of NGC 3312. Also known as Abell 1060, the Hydra galaxy cluster is one of three large galaxy clusters within 200 million light-years of the Milky Way. In the nearby universe, galaxies are gravitationally bound into clusters which themselves are loosely bound into superclusters. Superclusters in turn are seen to align over even larger scales.
