Server Raid 5 data recovery case
The case shared this time is a raid disk array in a server. There are 12 disks in the disk array, and the capacity of a single disk is 500G. ext3 file system, the s

Algorithm – How does the router organizes the routing table?
How does a router organize its routing table to quickly serve crashed packets? This is more like a programming problem, I’m looking for:

WeChat two signature algorithms MD5 and HMAC-SHA256
In the process of developing the WeChat interface, sometimes I find that the signature verification fails. The same signature logic is that some interfaces run through, and I found a lot of pits af
Implementation and application of MD, SHA, Mac Message Summary Algorithm
1. Message Digest Overview Message Digest is also called Digital Digest. It is a fixed-length value that uniquely corresponds to a message or text, and it is generated by a one-way Hash encryption
In-depth analysis of NOSQL database distributed algorithms
Abstract: Although the NoSQL movement did not bring fundamentals to distributed data processing Technological changes, but still triggered overwhelming research and practice on various protocols an
Algorithm – Difference between OT and CRDT
Can someone briefly explain the main difference between Operation Transformation and CRDT?
As far as I know, both are algorithms that allow data to converge on different nodes in a distribute

Algorithm – Quick filtering data structure (DELPHI)?
I am optimizing a part of a Delphi application, where the list of objects is often filtered using different criteria. The objects are stored in the TObjectList structure, and each filter is usually
32-bit checksum algorithms better than CRC32 quality?
Are there any 32-bit checksum algorithms:
>The small hash collision probability of the input data size The collision hits are more evenly distributed.
These are relative to CRC32. I act
