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.

M82: Galaxy with a Supergalactic Wind

M82: Galaxy with a Supergalactic Wind

Why is the Cigar Galaxy billowing red smoke? M82, as this starburst galaxy is also known, was stirred up by a recent pass near large spiral galaxy M81. This doesn't fully explain the source of the red-glowing outwardly expanding gas and dust, however. Evidence indicates that this gas and dust is being driven out by the combined emerging particle winds of many stars, together creating a galactic superwind. The dust particles are thought to originate in M82's interstellar medium and are actually similar in size to particles in cigar smoke. The featured photographic mosaic combines images taken in visible light from the Hubble Space Telescope and images taken in infrared light from James Webb Space Telescope. It shows the light-colored central galaxy nearly edge on across the image center with tremendous orange and red colored filaments of gas and dust extending both up and down. The filaments extend for over 10,000 light years. The 12-million light-year distant Cigar Galaxy is the brightest galaxy in the sky in infrared light and can be seen in visible light with a small telescope towards the constellation of the Great Bear (Ursa Major).
