    Photons are the smallest unit of energy that can be transferred between a light wave and a different particle.

    That is a much better description than what I have heard for the last 30 years: “A photon is a packet of energy”. That made no sense to me back then, and makes no sense to me now and, IMHO, doesn’t quite give a good visualization. It’s a placeholder, and I suppose it is slightly accurate depending on how “packet” is defined.

    That’ll break a few brains. To elaborate with an example: From the perspective of a photon, it’s “life” is over as soon as it begins. Even though it takes about 8 mins for a photon to travel from the sun to the earth from our perspective, no time at all has passed for it.

    (Correct me if I misspoke.)


  • Maybe. People with more technical knowledge should understand that LLMs aren’t magic or sentient and have some severe limitations. Hell, I have been tinkering with ML and ANNs for a better part of 15 years or so and they can be extremely useful. (I am no expert and never indend to be.)

    It’s the marketing wank, scams, art theft and all the bullshit that pisses me off now. In that regard, I am squarely in the “Fuck AI” category. There is absolutely nothing phenomenal that has come of this recent bubble in the commercial space. AI generated images are mostly trash, articles are riddled with gross factual errors, phishing and other scams are more realistic (and maybe even more dynamic) now and public forums contain even more annoying bots. And the worst bit is that AI generated media, like music, is just a collection of averaged values with no originality.

    That bell curve represents something but it isn’t IQ.





  • Of course I do, but its very conditional in your case. For the record, I did miss that you had port forwarding enabled already and read your post as if you were just trying to connect to the open internet and see any traffic going to some rando servers. That would be a very different situation.

    How is the traffic proxied locally? Does the VPN client even allow inbound connections? Is a virtual interface configured for the VPN and is there an inbound port open?

    What makes this situation conditional is that there are several ways your VPN client could be configured and it is my guess that it is the bottleneck in this case. If you tried every address that you could find and saw nothing, chances are, there is no traffic to be seen. Any stateful firewall will drop an inbound SYN or traffic not related to an established connection.

    Your routing table may give some good clues as to where traffic is going as well. For example, the VPN client could be creating a local default gateway IP. Unless there is a split path configured, all traffic should be traversing that IP, regardless of what it is.

    So, can you elaborate more on the route your traffic is taking? Listening on 0.0.0.0 can sometimes work, but usually a specific interface needs to be defined as well. In some cases, tcpdump setting the interface to promiscuous mode can break things.

    Also, it’s a VPN. How traffic is getting routed in through the tunnel could be problematic. I have just been assuming that everything is fine up to the client you use and the computer sending traffic to inside your network is part of the VPN.


  • Ok, you are putting the cart a few steps before the horse here and put simply, you can’t just tap the entire Internet from behind your own Internet connection and “through” a VPN. (A VPN “tunnel” is a bit misleading on how traffic is seen in the wire, but that is still many more steps ahead.)

    Watching pcap is cool, but you need a fundamental understanding of networks and network protocols before you can actually see more than characters of the Matrix and understand what you are tapping into from the start.

    To kick off your own research path, start reading into the OSI Model, TCP vs UDP, traffic routing and subnetting. You need to understand where you need to be to see the traffic you want to see first.

    Unfortunately, I can’t begin to answer your question without some foundation in place first.






  • While young birch stems can taste almost minty, it’s not going to do much to attract honeybees. The chances of those being honeybees is minimal. It’s possible, but unlikely. If the bees have the opportunity, they will probably be camping next to fruit trees of some kind instead.








  • Now after almost 3 years, Russia not only hasn’t managed to take Ukraine, but has lost territory to them too. For months now Russia has still not been able to take it back!

    That was a battle cry for a tankie to show up and produce a different statistic. FYI, it’s usually a time capped chart that limits data in Russia’s favor.

    War is a dynamic phenomenon, after all. (You can usually take a specific block of time from any point and produce a favorable result by limiting which variables are used. This is why internet charts and graphs must always be verified, actually.)
