Difference between data section and the bss section in C The nice part about this is, the bss section data doesn't have to be included in the ELF file on disk (ie there isn't a whole region of zeros in the file for the bss section) Instead, the loader knows from the section headers how much to allocate for the bss section, and simply zero it out before handing control over to your program

c - Why is the . bss segment required? - Stack Overflow The bss segment is an optimization The entire bss segment is described by a single number, probably 4 bytes or 8 bytes, that gives its size in the running process, whereas the data section is as big as the sum of sizes of the initialized variables Thus, the bss makes the executables smaller and
c - what is the purpose of . bss? - Stack Overflow Typically only the length of the bss section, but no data, is stored in the object file The program loader allocates and initializes memory for the bss section when it loads the program Operating systems may use a technique called zero-fill-on-demand to efficiently implement the bss segment (McKusick Karels 1986)
linux - Why use . data instead of reserving space in . bss and . . . When Linux loads an ELF binary, it maps the bss section to a dedicated zero page marked as copy-on-write (see: How exactly does copy on write work) So there is no overhead to initialize that page to zero In some cases, bss may occupy a fraction of a page (See for example Gnu assembler data section value corrupted after syscall)
where should the . bss section of ELF file take in memory? To know where the bss segment will be in memory, it is sufficient to run readelf -S program, and check the Addr column on the bss row In most cases, you will also see that the initialized data section ( data) comes immediately before That is, you will see that Addr+Size of the data section matches the starting address of the bss section
Good guide from beginner to late game? : r BeeSwarmSimulator - Reddit The spark staff isnt worth the investment its not a big increase from the golden rake's collection If you don't already have the golden rake, its a great upgrade from the bubble wand and if you really like bubbles, you can add a bubble bee or two to your hive, they naturally spawn bubbles (and once you get good enough for mythics tadpole bees do too)!!!
