Solana NFTs Can Be Minted Without Metaplex Using Token Extensions

·1 views

A developer experimenting on Solana's devnet discovered that NFTs can be created using only the Token Extensions (Token-2022) program, without relying on Metaplex or any separate metadata program. On Solana, an NFT is simply a token mint configured with zero decimals, a supply of one, attached metadata, and a disabled mint authority. Over three days, the developer minted a standalone NFT, a collection mint using the Group extension, and two member NFTs linked to the collection via the Member extension. Metadata is mutable by default, meaning the update authority can change fields like name, symbol, and URI at any time, though on-chain updates reflect instantly while off-chain image caches may lag. The developer noted that Token Extensions offer a lighter, more composable alternative to Metaplex, with potential for protocol-level royalty enforcement via transfer fees.

Why Switzerland Offers 25 Gbps Internet While the US Still Lags Behind

A blog post published on stefan.schueller.net argues that Switzerland's superior broadband infrastructure exposes flaws in free-market internet policy. The author contends that Switzerland's regulated telecom environment has enabled residential internet speeds of up to 25 Gbps, far exceeding typical US offerings. The piece suggests that government intervention and infrastructure investment, rather than pure market competition, are key drivers of Switzerland's connectivity advantage. The article has gained attention on Hacker News, sparking broader discussion about broadband policy differences between Europe and the United States.

Understanding Variable Scope and Shadowing in Go With Code Examples

In Go, variable scope is determined by lexical scoping, where a variable is only accessible within the block it is declared in. Variable shadowing occurs when an inner block declares a variable with the same name as one in an outer scope, effectively hiding the outer variable within that block. Go allocates separate memory for the inner variable, so changes to it do not affect the outer one. This behavior is a common source of subtle bugs, particularly when the err variable is accidentally shadowed using := instead of = inside loops or conditionals. Developers are advised to choose variable names carefully to avoid unintentional shadowing.
