Maximum table size for a MySQL database

I once worked with a very large (Terabyte+) MySQL database. The largest table we had was literally over a billion rows. It worked. MySQL processed the data correctly most of the time. It was extremely unwieldy though. Just backing up and storing the data was a challenge. It would take days to restore the table … Read more

Scale down to fit an image in FOP

I found this page here explaining how scaling works with XSL-FO. Essentially, this is the snippet that I used to make it work: <fo:external-graphic src=”https://stackoverflow.com/questions/6220316/url(“https://stackoverflow.com/questions/6220316/…”)” width=”100%” content-height=”100%” content-width=”scale-to-fit” scaling=”uniform” xsl:use-attribute-sets=”img”/> I found that width=”100%” was the missing piece in your own attempts. Hope this helps future visitors.

Whats the size of an SQL Int(N)?

It depends on the database. MySQL has an extension where INT(N) means an INT with a display width of 4 decimal digits. This information is maintained in the metadata.

You can Read more here. I’d write more, but for some reason the cursor is jumping around all over the place on my phone. Edit: This … Read more

Getting terminal size in c for windows?

This prints the size of the console, not the buffer: #include <windows.h> int main(int argc, char *argv[]) { CONSOLE_SCREEN_BUFFER_INFO csbi; int columns, rows; GetConsoleScreenBufferInfo(GetStdHandle(STD_OUTPUT_HANDLE), &csbi); columns = csbi.srWindow.Right – csbi.srWindow.Left + 1; rows = csbi.srWindow.Bottom – csbi.srWindow.Top + 1; printf(“columns: %d\n”, columns); printf(“rows: %d\n”, rows); return 0; } This code works because srWindow “contains the … Read more

Is bool guaranteed to be 1 byte?

Rust emits i1 to LLVM for bool and relies on whatever it produces. LLVM uses i8 (one byte) to represent i1 in memory for all the platforms supported by Rust for now. On the other hand, there’s no certainty about the future, since the Rust developers have been refusing to commit to the particular bool … Read more
