So WestConnex was totally going to solve traffic in Sydney by adding more lanes for cars. Just a few teething problems on the Rozelle Interchange and it'll all clear up, they said. in c/[email protected]

Well, the Rozelle interchange was never intended to improve traffic for the surrounding suburbs. It's meant as an addition to the M4-M8 so they can connect to the northern side of the bay.

It works as designed™

Any "fix" they claim to do is an attempt to calm the public.

Anecdotally, when i drive the WCX to work it saves me an hour each way, but it is always empty

Can you recommend a book for me please? in c/[email protected]

This year I discovered the Elderling Saga, by Robin Hobb. Starts with the Farseer Trilogy, Assassin's Apprentice. Great epic fantasy.

As for sci-fi Isaac Asimov's Foundation is great.

Neuromancer is also a great read, and one of the earliest examples of cyberpunk.

Since you asked for a single book, and you might not be keen on jumping into multi-book sagas, I'd say go for Neuromancer

Feedback on Design and Firewall Options (lemmyf.uk)
 

All the cool projects I see while lurking around here have thrown me into the world of Self-Hosting! Some months ago I got myself a NAS, flashed it with TrueNAS and started playing. Today, I am ready to face the creation of my first homelab.

Since I got the basic data storage working, I decided to continue with the Firewall setup. I’d like to have my security figured out before I start spinning up machines, playing with their configs and unwittingly opening all kind of arcane doors to the unknown. So I turn to the Fediverse!

I’d like to create the standard network with a DMZ. Within the network, I plan to use VLANS to manage traffic between devices, and the firewall to limit internet access.

This is a sketch of what I think I want to achieve:

Connections

  • The Consoles will connect only to the internet
  • The Home Devices (printers) will connect only to the Home WKS
  • There will be a NAS device hosting VMs with services accessible only from the home network:
    • The Home Automation will connect to IoT
    • The Recipes will connect to Home Wks
    • The Data Archive will connect to Home Wks
    • Jellybean will connect to:
      • Home Wks
      • TV
    • *arr Stack will connect to:
      • The Internet
      • the NAS (presumably Jellybean)
  • The Home WKS connect to pretty much anything

Available Hardware

  • OpenWRT compatible Router
  • 2.5gbs Unmaged Switch
  • 1gbs Unmaged Switch
  • QNAS with 2x2.5gbs NIC, running TrueNas
  • A few Rpis of different specs

Questions

Firewall

My Main questions relate to the Firewall. It seems that pfsense is the way to go for a SW Firewall:

  • What HW should i use? would a Raspberry pi 4, 4GB RAM work?
  • What do you think of Netgear 1100?
  • I like this device since 3ports would allow me to create a physically separate DMZ
  • Should I consider other firewalls?

NAS

For Bonus Points, some questions regarding the NAS:

  • With my current diagram, it seems like it is not possible for the NAS to receive updates from the internet. The obvious change is to place the NAS within the DMZ, but I’d like to keep the Data Archive as far from the net as possible
  • Should i locate the entire NAS in the DMZ?
  • My TrueNas has 2x2.5Gb ports. Can i connect each NIC to a different network? Would this have any benefit?

Thanks for your time!

Do both sides of a transformer need to be fused? in c/[email protected]
[–] [email protected] 0 points 8 months ago (1 children)

My Electromagnetics is a bit rusty, apply a healthy measure of skepticism:

I'd say the two fuses are there to protect the transformer itself.

In the example you use, the upstream of the transformer would be protected by the 280V fuses but the transformer itself will have to suffer the overcurrent, and could be damaged by it. If the transformer is dipped in cooling oil, the overcurrent could even lead to an explosion.

As for the TUV inspection, the two fuses would be desirable for any TUV cert, and they would be required if there is any chance of explosion.
