256 Bit Integer commented uint256.cpp from Bitcoin Core source code
If you’ve developed systems in C or C++ before then you’re probably familiar with the stdint.h (cstdint for C++) typedefs. Since there’a lot of variation between platforms, stdint.h standardizes integer type names in an intuitive way. A uint8_t is an 8-bit unsigned integer and a uint64_t is a 64 bit unsigned integer. What you won’t […]
C++ Bitcoin Blockchain to MySQL Database Interface
Crypto.BI Toolbox abstracts database access through a thin database access layer. Every database operation required to run the system has been made into a separate function in db/dao/CBDAODriver.h This traditional approach, used in many system architectures, allows us to switch storage solutions by creating new subclasses of CBDAODriver. For instance, if a graph database was […]
A program to send and handle every UNIX signal
While playing around with errno I decided to test what happens if I sent (and handled) every possible UNIX signal to a program. Running this as a non-root user, I figured I couldn’t break anything if I tried – so I went ahead and ran it. Let’s see: I skipped sending SIGKILL (9) for obvious […]
Bitcoin Blockchain to MySQL Insertion Tool
Crypto.BI Toolbox comes with a raw .dat block file to MySQL insertion tool called blocks_inserter. To use it, first you’ll need to generate the MySQL schema on your local server by importing scripts/sql/mysql/cryptobitoolbox_bitcoin.sql into your MySQL server. Then you will need to configure Toolbox with the appropriate username, password, host and database so that Toolbox […]
