  • Computer algorithms solve problems all over the world for companies already. I bet airlines already have teams of people using computer algorithms to figure crew management, flight routing, cost optimization, etc.

    The fact that they’re exploring quantum computers and non-classical algorithms just suggests that gate allocation is NP-Hard. Sure things go wrong when computers fail already, Look at Southwest or Delta’s recent meltdown, but to act like this a bad thing is just nonsense. This should be looked at as a good thing that airlines are working on.


  • Why do you think this is going to replace air traffic control work? It’s picking which gate to park the plane at. This was done by airline and airport operations teams, not ATC. Imagine if you could automatically pick gates to reduce the time a plane spends taxiing and/or minimize time passengers spend walking. That’s 100% a useful application for computer optimization algorithms. Humans aren’t going to do that better and it’s not a function of safety that tower or ground control needs to do.




  • This is my biggest challenge with this extension. What’s clickbait to one person is not to another. Several times I’ve come across titles that get mangled when rewritten to lose key points. Or the image gets replaced with a random screen grab. There’s a difference between somebody doing the YouTube face and a title with “the craziest stunt you’ve ever seen” and an artist photo with a title saying the “a crazy stunt jump through a burning hoop”. I’m okay with the latter but dearrow will often remove crazy. The is just an contrived example

    One person could still say “crazy” makes it clickbait, but having some adjectives are fine






  • As a professional software dev, I worked with pretty much every OS daily. My personal computer was a Windows, my work laptop was a Mac, and I ran my code on Linux so I was familiar with the things I liked and disliked about each. I also ran my own set of server with my websites, mail servers, and various research projects to learn and grow.

    Then I decided it was time to order a new laptop and I didn’t want to go to Windows 11 because I felt Microsoft was going too much into features I didn’t want like Ads, more tracking, pushing AI. Don’t get me wrong, I like AI, but it was too much about forcing me to use it to justify their stock valuations.

    I also was working on reducing my usage of big tech, setting up self hosted services like pi-hole, Home Assistant, starting to work my own Mint alternative. It just felt natural to get a Framework laptop and try running Linux on it.

    I still have a Windows desktop for games and other things, I still use Mac at work. I still like the Mac for it’s power efficiency and it doesn’t get as hot. Linux has some annoyances here and there, like dbus locking up, or weird GNOME issues, or for a while my screen would artifact until set some kernel params, or the fact that my wifi card would crash and I had to replace it with an Intel card, but I’ll stick with it.


  • There’s two main ways of doing geo-based load balancing:

    1. IP Any-casting - In this case, an IP address is “homed” in multiple spots and through the magic of IP routing, it arrives at the nearest location. This is exactly how 1.1.1.1 and 8.8.8.8 work. It works fine for stateless packets like DNS, however it has some risks for stateful traffic like HTTP.
    2. DNS based load balancing. A server receives a request for “google.com”, looks at the IP of the DNS server and/or the EDNS Client IP in the DNS query packet and returns an IP that’s near. The problem is that when you’re doing Wireguard, it goes phone -> pi-hole (source IP is some internal IP) -> the next hop (e.g. 1.1.1.1 or 8.8.8.8), which sees the packet is coming from your home/pi-hole’s public IP. Thus it gets confused and thinks you’re in a different location than you really are. Neither of these hops really knows your true location of your phone/mobile device.

    Of course, this doesn’t matter for companies that only have one data center.


  • Sorry, what do you mean route it directly? Maybe I didn’t clarify well enough.

    My DNS is routed over the VPN but Internet traffic is routed directly. The problem is the load balancing is done based on where the DNS server is so say Google even though the traffic egresses directly to the internet bypassing the VPN it still goes to a Google DC near my home. Not all websites do this so its not always an issue.
