“When he reached the New World, Cortezh burned hish ships. Ash a reshult hish men were well motivated.” —Capt. Ramius, played by Sean Connery in The Hunt for Red October

This is all I’ve run across on reverse engineering, so far but it is quite interesting.

Remember Star Trek III…?

Well maybe they aren’t experienced info security professionals :)

Idk what you’re into buddy

but I like it.

Inflation.

I think you win.

If you haven’t yet, give Lief Ove Andsnes’ rendition a try.

Everyone has their favorite interpretations, I guess. This is one of mine. From a pianist that impressed the hell out of me when I first heard him.

(The album Horizons if the link doesn’t work or you’re boycotting Spotify or whatever)

Dvorak Symphony No 9, Largo

God I am getting crazy goosebumps just listening to this again. I love the 9th symphony so much.

Oh wow that is amazing. Thank you!

I forgot how much I love this kind of choral music.

I get where you’re coming from but is he managing his risk or not?

Does he understand the risk? If yes, good. No? Bad.

Is he ignoring the risk? If yes, bad. No? Good.

Is he weighing the risks against the benefits he receives of using these apps and taking appropriate steps to mitigate those risks? If yes, then good. No? Bad.

Cyber security isn’t “lock everything down at all costs”. Otherwise I would insist you throw your phone in an incinerator along with all your computers, live in a bunker reinforced against nuclear attack with a small army to guard you, never leave it, never talk to anyone… Etc.

It is enabling one to achieve their goals with a tolerable amount of risk. That level of tolerable risk is different for everyone.

Best I have ever had was this, but on cibatta with a spicy Cajun mayo type spread. From a local deli chain in Denver.

What are you trying to achieve?

Indeed. The message: you’re helpless. Just sit around and wait to be rescued. Any minute now…

Perhaps that’s also why superhero movies were so popular for a time recently.

Physically, at the physical / link layers, an Ethernet transceiver integrated circuit is used that knows how to take data provided by the cpu and communicate it by sending signals along the RJ45 Ethernet physical layer to communicate with the switch. By looking at the datasheet and IEEE 802 specs one could figure out more detail.

It’s kind of horrifying nobody thought that through. What else did they fail to think about?

Neanderthals (and humans for that matter) did indeed but they did it in groups, usually. Being alone really stacks the odds against you I think.

“Time Enough at Last”

The circuitry doesn’t determine which cable is the correct one. That is determined by a protocol that associates various IP networks with different network interfaces. So, for example, all data going to 192.168.5.0/24 goes to interface eth0, and 192.168.0.0/24 goes to eth1 and 10.0.0.1 goes to eth2 and so on. Each interface is a separate RJ45 Ethernet port on your router, for example. It doesn’t have to be RJ45 it could be your router has a Thick Ethernet or Thin Ethernet connector. Or it could have wifi. Or something else.

Anyway, forwarding the packet to the correct interface / subnet can be done with a static route defined on the router. Another way is dynamic routing using BGP (border gateway protocol) which is an exterior gateway protocol that dynamically routes between your network and somewhere exterior to your network. Yet another protocol is OSPF (open shortest path first) which is used inside a corporate network for dynamic routing.

For any of these the router knows how to send the IP packet to the next hop, another router, which in turn knows how to send it to the next hop.

Where to send is based on the destination IP. The routers know which interfaces and which other routers are responsible for different subnetworks.

It is sort of like how once your mail makes it to a main hub in your state, it is then routed to the main hub for the destination state, and from there to the post office responsible for the destination zip code, and then to the mail route (and hence truck) responsible for the street and number.

So if your destination is 1.1.1.1 maybe there is a router known to be responsible for 1.0.0.0/8 and then it knows what router is responsible for 1.1.0.0/16 and so on until we get to a router that has 1.1.1.1 on one of its subnets then it sends directly to 1.1.1.1.

That first one is where I feel I’ve seen myself and others get downvoted more than anything else listed here. Maybe it is recency bias from that one thread the other day lol.
