Welcome to Nebula Core!

Nebula Core is a privately owned an operated "cloud services" provider built and maintained by Victor Rossi, a hobbyist designer, photographer, and tech enthusiast. Nebula Core is the central component in a growing network of machines and services, and aims to reduce Nebula users' reliance on major cloud platform providers like Google or Amazon.

If you've got a Nebula account (formerly Catserver account), log in with your credentials in the upper right. Having an account allows you to access the full array of features and services offered by Nebula Core, and allows you to provide some feedback, if you see fit. It's pretty neato.

If you need an account, send me an email and I'll set you up. Due to limited resources, accounts are only provided to friends and family at this time.

2017-03-03: Botnet Attack, Cloudflare, and more

It came to my attention that, hosted on Nebula Core, was getting hit with a botnet attack targeting a particular Wordpress file. The typical reason for an attack like this would be to brute force an account password for the Wordpress install, possibly to install malicious code that would turn my server into a member of the botnet. This doesn't seem to have happened, but to help mitigate further attacks like this I've configured all Nebula Core sites with Cloudflare's DNS proxy service, with a few exceptions that require direct access. This means you may have to change the way to access Nebula FTP, Remote Desktop, Minecraft, or other direct connect services. Generally, connecting directly to the service (directing your client to, for example) should work. Cloudflare also works as a caching service, meaning page loads to static sites like should be marginally faster.

I've also began setting up a new N

2017-02-12: Nebula Core Security Updates

SSL Authentication has been enabled on several sub domains, finally. I'll need to make a number if changes to the main site (here) for SSL/HTTPS to work without breaking things, so that might be my next project. I've also fixed an issue that limited data rates to and from the server to a fraction of their maximum capacity, which should allow for a noticeable improvement in transfer speeds.

At the moment, SSL should be working on the following sub domains with a valid certificate:
- (required for mobile app access)

Good night everyone!

2017-02-11: Cloud Storage and Server Updates

Hey everyone,
I recently launched a web-based interface that'll let you access and manage your Nebula Core file shares, powered by Nextcloud. You can access it at Consider this feature as ALPHA at this point, as it's undergone very little testing. I've created accounts manually for Nebula Core's top contributors, but if you're unable to login you can contact me and I'll set you up an account. Here are some things to keep in mind:

- Files uploaded via FTP or via local file sharing services need to be placed in /files to be visible by Nextcloud. This allows some flexibility as to what you want in your cloud share. Anything uploaded via the web is accessible immediately, but files uploaded traditionally are scanned in every day around 3 AM. I recommend using for everything other than bulk file transfers from this point forward.

- You'r

2016-07-21: Server upgrades, more downtime

Some of you may have noticed that the server's dropped offline a few times recently. I've moved to a new condo, upgraded my internet speed, got new network hardware, and now it's time to address some of the problems with Nebula Core. To ensure no data is lost during the upcoming hardware change I've replaced some of the aging drives in the system and backed up all of the user data. So no need to worry about that.

So what am I doing exactly? Well, I've decided to step up to a real server platform - albeit a slightly older one, to suit my budget. The current low power Intel SoC platform I'm using has been great, but limited PCIe bandwidth has really hindered storage performance and expandability more than I anticipated. The new system will feature Xeon processors, IPMI (so I can more easily address errors remotely), much faster memory performance, and (most importantly) 10-gigabit networking. Page load times should decrease slightly, read/write perfor

2016-02-11: Adding Freesync (or G-Sync) to an Older Monitor - Possible?

Almost two years ago I purchased a Samsung U28D590D 4k monitor from eBay, before it was officially released. At the time, it was the cheapest 3840x2160 60hz monitor to ever hit the market, and it even had some pretty stellar specs for a mid-grade TN panel. With a 1ms response time, 10-bit color (using frame-rate control), and multiple 4k compatible inputs, it seemed like a super appealing option. This was until six months later, when it was revealed that the u28D590D's successor, the u28E590D, would support AMD's new Freesync technology, being one of the first to do so (and possibly the first with 4k resolution). Despite being otherwise satisfied with the monitor, I couldn't help but feel a bit of early adopter's remorse.

But wait, I thought to myself! The monitors are basically the same, right? Can't they just release a software update for the older ones to add Freesync? Well, no. Aside from lacking a USB port to receive updated firmware, Freesync i
