  • Some self hosted services refuse to work if you use a self signed certificate with your public facing IP. They only allow self signed certificates when using one of the handful of private addresses.

    Some apps on mobile devices for the service you use won’t work unless a trusted certificate is used. A self signed certificate behind the scenes creates an error that isn’t handled and you can’t connect.

    You lose the ability to have a proxy in front to handle abuse so your server is spared the headache. You need a domain to do this.











  • It’s not odd at all. It’s well known this is actually the truth. Ask any video editor in the professional field. You can search the Internet yourself. Better yet, do a test run with ffmpeg, the software that does encoding and decoding. It’s available to download by anyone as it’s open source.

    Hardware accelerated processing is faster because it takes shortcuts. It’s handled by the dedicated hardware found in GPUs. By default, there are parameters out of your control that you cannot change allowing hardware accelerated video to be faster. These are defined at the firmware level of the GPU. This comes at the cost of quality and file size (larger) for faster processing and less power consumption. If quality is your concern, you never use a GPU. No matter which one you use (AMD AMF, Intel QSV or Nvidia NVENC/DEC/CUDA), you’re going to end up with a video that appears more blocky or grainy at the same bitrate. These are called “artifacts” and make videos look bad.

    Software processing uses the CPU entirely. You have granular control over the entire process. There are preset parameters programmed if you don’t define them, but every single one of them can be overridden. Because it’s inherently limited by the power of your CPU, it’s slower and consumes more power.

    I can go a lot more in depth but I’m choosing to stop here because this can comment can get absurdly long.

    Linux uses half the RAM Windows does in a fresh install. 8GB can absolutely be done on a Linux system without worry. To aid systems with 4-8GB RAM, Windows compresses. This has allowed OEMs to ship systems with 8GB as a minimum. This just isn’t enough for multitasking. The CPU is tasked with constantly compressing and decomposing if you’re attempting to multitask. This can make an already cheap laptop feel a little more sluggish. 16GB has always been the minimum for gaming systems and these days it’s becoming apparent 32GB is needed. 8GB is just pitiful for a computer these days.


    Addressing the OP, mobile devices used to only need 2-4GB for the longest time. The OS wasn’t that heavy because the ARM CPU could only do so much. As the CPUs improved, higher resolutions were used, prettier animations and more features got added. This all needs more RAM. Android developer options will tell you how much RAM you’re using. A feature of Android is to keep a process cached in RAM that’s been recently used. This is present to aid in battery life. Even if you swipe the app away from recents list, a portion is cached so the next time you start it, the CPU doesn’t have to work as hard to load it up. You can see this under Running services > Cached processes. This means it’s more beneficial for the mobile device to have more RAM.




  • You always will. Welcome to the Internet. The difference is whether or not you’ve taken steps to secure your stuff. You need to understand what this malware is looking for. It’s explicitly looking for unsecured services. Such as WordPress, SQL, etc. There are inexperienced users out there that inadvertently expose themselves. I see this type of probing at work and at home. Don’t overly stress it. My home server has been running for a decade without issues. Just keep it updated and read before you make any changes if you don’t fully understand the implications.

    My home based server is behind a pfsense firewall. Runs Arch. Everything is in a non-root docker container. SELinux is enforced. All domains are routed through Cloudflare. Some use Cloudflare Zero Trust.


  • Oh my. You’re doing it wrong. Exposing the unencrypted connection without the proper security measures is putting yourself at risk. Regardless of how strong you set the password, the connection can still be abused in all manner of ways. If you read the jellyfin documentation, you’d see the developers clearly state you should never do this. You need to put Jellyfin behind server software. Specifically a reverse proxy. I use NGINX. You can setup your connection to be secure this way. You can now also use Cloudflare if you have cache turned off. And if you really wanna go the extra mile, route it behind a VPN. Though this makes it harder for those you share it with or some devices that don’t support VPN.

    Please revise your connection. If you need help, feel free to reach out.


  • Office doesn’t have native Linux binaries. You either have to use a VM or Wine. You’ll find most people recommend a VM. There are Office web apps, but they’re not as robust as the Windows native offerings. Microsoft doesn’t really want to offer Office on Linux. Stick with Windows for the remainder of your education. Once you’ve finished, you can sink time into learning Linux.
