port forwarding is a technique used to redirect communication requests from one address and port number combination to another while the packets traverse a network gateway, such as a router or firewall. it allows external devices to connect to specific services within a private network by forwarding traffic from a public ip and port to an internal ip and port.

in ethical hacking, tunneling refers to a method used to transfer data between two networks or systems through a secure, encrypted connection. it's typically used to bypass security controls or firewalls and allows for the secure transmission of sensitive information. tunneling encapsulates one type of network protocol inside another, ensuring that data can be sent without being detected or blocked.

aggressive gas fees in crypto refer to extremely high transaction fees that users pay to prioritize their transactions on a blockchain, especially during periods of high network congestion. in blockchains like ethereum, gas fees are paid to miners for processing and validating transactions, and they fluctuate based on supply and demand.

The Romans had a form of "fast food"! Ancient Rome had street vendors and small shops called "thermopolia" (singular: thermopolium), where hot food and drinks were sold to passersby. These shops were especially popular with the working class and those without kitchens at home. Archaeological finds in places like Pompeii show beautifully decorated counters with embedded jars (called dolia) that held food like stews, bread, and wine. It was a sort of ancient version of takeout!

end-to-end encryption (e2ee) is a security method that ensures only the communicating users can read the messages. it encrypts data on the sender's device and keeps it encrypted while it is transmitted over the internet until it reaches the recipient's device, where it is decrypted. not even the service provider can access the messages.

a non-custodial wallet is a type of cryptocurrency wallet where the user has full control over their private keys and, therefore, their funds. unlike custodial wallets, where a third party (like an exchange) holds the private keys on behalf of the user, a non-custodial wallet gives the user sole ownership and responsibility.

stablecoin is a type of cryptocurrency designed to maintain a stable value by being pegged to a reserve asset, typically a fiat currency like the us dollar, euro, or other commodities like gold. the goal of stablecoins is to combine the benefits of cryptocurrencies (like fast transactions and blockchain security) with the stability of traditional currencies.
