Show HN: SnowId – A Decentralized, K-Ordered, 128-bit UUID library in C
Sharing my project inspired by twitter snowflake UUID generator but that supports:
1) Longer range of id's to be generated.
2) No coordination with other machines in the distributed system.
- __ryan__ 4y agoShow an example of the generated id.
- beyonddream 4y agodone.
- orf 4y agoWhy use this over the new ordered UUID RFC?
- beyonddream 4y agoUUID RFC use <timestamp, sequence, node id> layout which is different from the layout of snowid scheme which is <timestamp, node id, sequence>. Also UUID RFC timestamp can only use up-to 60 bits whereas snowid has the full 64 bits to spare. They server different use-cases.
- lijogdfljk 4y agoPossibly a tangent, but what is the "dot notation" described in: # hexadecimal representation of 128-bit id's in dot notation 0:0:1:84:40:9b:ff:a5:2:0:12:ac:42:3:0:0
- beyonddream 4y agoGood eye! That was a typo. It should read as "colon notation". It is just a visual representation of 128 bits (16 bytes) with each byte separated by colon ":". I have updated the readme with an example. One place where you will see this notation visually is MAC addresses.
