  • Metronet will be supplying an Optical Network Terminal, probably like this one:

    This is basically the equivalent of a modem for cable networks. It does not provide routing functions. You’re probably stuck with the ONT they supply, but it shouldn’t matter much, definitely not for anything internal.

    It looks like Metronet normally supplies Eero WiFi mesh devices for home networking - are the ones you currently have supplied by Metronet? They might just replace the modem with the ONT and leave the existing Eero gear, or they might upgrade the Eero gear to support the higher speed available on the fiber network.

    In any case, if you are using ISP-supplied network devices then you don’t control the router, which means you can’t set up things like port forwarding to access your home network from outside, or configure VLANs to segregate devices on your network, or control things like DHCP.

    Technically there’s no reason you have to use the Eero devices from Metronet, you should be able to plug any router into the ONT WAN port and have internet service. If you don’t want to get too deep into network config, then any modern consumer WiFi router will work (but not a modem/router AIO device). If you want to have a bit more control, look for one that supports OpenWRT.




  • You’re welcome. I tried to do basically the same thing a few years back (run a WordPress site from a RPi on my home network - and also a Minecraft server) and so I tried to write up the problems I ran into - I probably forgot some, but those are the major hurdles. I learned a lot along the way.

    I should also point out that if you rent hosting space (from linode or inmotion or digitalocean or many other options) then problems 1 & 4 become much easier, and 2 & 3 go away entirely (most people don’t host public websites on their home networks because of these and other issues).

    Happy to help. If you’re interested in learning networking more thoroughly, I want to point you to Professor Messer especially the Network+ content. He has far more complete explanations than I could write (and it’s free!). Even if you’re not interested in getting any certs, the explanations will be helpful.


  • So your goal is to host a publicly accessible static website from a computer in your home. There are a few problems you need to overcome before even worrying about configuring any software. You need some more basic networking knowledge first.

    1. Basic Networking Theory - you should read a brief explanation of the OSI 7-layer network model. You don’t have to try to memorize this and you won’t really understand it until you start actually doing stuff, but you should read it for some basic terminology and to understand that there are distinct steps through which communication between computers happens.

      When you start running into problems (“why can’t I access the server? I did all the tutorial steps”), figuring out which layer the problem is in will help guide you to the solution:

      • is there a bad cable? -> 1. Physical
      • do I have the right IP address? -> 3. Network
      • is the firewall port closed? -> 4. Transport

    1. Privacy/Security/Safety - don’t host a publicly accessible website from your personal computer. Just don’t. To make this happen you will have to open a hole in your network security that makes your computer accessible from the public internet. Don’t do this on your daily driver computer. Don’t do this with any device that has any files on it that you care about or any access to any personal information. Don’t.

      Set up your web server/learning environment on a clean, dedicated system. This could be an old laptop or a Raspberry Pi (an older 3B model will work just fine for this) or whatever cheap computer hardware you have, as long as it can run Linux and has a physical network port (using WiFi will give you extra headaches for getting this working). If you think you might want to expand your projects in the future, you can get a used Dell server for very little money, and add more hard drives as needed. Wipe the hard drive and install Debian or Ubuntu server as a base, there’s lots of resources out there for setting up web services on either.


    1. Restricted Ports - you are most likely on a residential internet connection. Most residential ISPs close ports for security reasons, especially 80. For example, here is Cox’s list of restricted ports. You will need to find your ISP’s equivalent list and understand what you can and can’t do with your connection.

      There are workarounds, primarily through port forwarding. You will need admin access to your router to set this up. I recommend that you read that entire article because it probably applies directly to your situation.


    1. Dynamic IP Address - most people still find it easier to work with IPv4 addresses - I won’t go into IPv6 right now, but you should read a little about it just for awareness. Your residential internet most likely has a dynamic IPv4 address, which means you can’t rely on that address staying the same forever (or even until next week), which means that you can’t configure your Cloudflare domain name to point to a single IPv4 address.

      Dynamic DNS is the solution for this, and again you’ll need admin access to your router to set it up.


    1. HTTPS/TLS/SSL - if you get through all those issues then you probably have a working website, but now you’re seeing something like this when you try to view it in your browser:

      This doesn’t mean that you can’t get to your website - it just means that you can only do it via HTTP and not HTTPS, which the browser is warning you (and anyone else trying to view your website) is not secure. You can either just accept that this alert will always come up, and that you have to click through it, or you can learn about TLS and getting an SSL/TLS certificate. This is a later topic - it doesn’t matter and probably won’t make sense until after you’ve got your web server online.










  • Like it or not, commercial computing is primarily Microsoft environments. Businesses are moving to Azure/O365, but there’s still a lot of on-prem AD out there, and a lot of businesses that are stuck in between with some form of hybrid hodge-podge. It’s definitely more difficult to do admin tasks for individual Windows endpoints vs. Linux, but on the other hand there is no FOSS equivalent for AD forest management. In a corporate environment, the ability to manage large numbers of endpoints at scale is more important.

    You probably shouldn’t be using iPerf3 on Windows, but instead use the native nttcp.

    tracert is included with Windows by default, no need to install a separate utility. robocopy is also included with Windows and can be used to do incremental backups if that’s your use case.

    If you have to manage Windows systems you should learn about Windows-native tools, rather than trying to drag the Linux-native tools you’re used to onto Windows just for the sake of familiarity.

    That said, installing (and updating) software on Windows is absolutely a pain compared to the relative simplicity of a Linux package manager and I’m 100% with you on that. I highly recommend chocolatey, which attempts to work as a package manager for Windows. All of the software that you install with chocolatey can be updated with a single command, similar to running updates in a package manager on Linux. If you can implement this on the Windows systems that you have to manage, it will make things easier.







  • The problem with this is that even if a machine is conscious, there’s no reason it would be conscious like us. I fully agree that consciousness could take many forms, probably infinite forms - and there’s no reason to expect that one form would be functionally or technically compatible with another.

    What does the idea “exact copy of our brain” mean to you? Would it involve emulating the physical structure of a human brain? Would it attempt to abstract the brain’s operations from the physical structure? Would it be a collection of electrical potentials? Simulations of the behavior of specific neurochemicals? What would it be in practice, that would not be hand-wavy fantasy?
