Note: Since I am well past my initial goal of reverse engineering the Open Trivia DB, creating a new DB, creating a basic PHP API, creating a feature to add new entries to the DB, and have added over 150 computer science related trivia entries in the DB, I will stop posting in this thread soon and start a new phase for this project sooner than later.
Hello guys!
Can say me anybody about operatios with unix, I don't to make operations, only inside in a variable, like this
#y=4
#x=2
#let z=$y-$x
#echo $z
# 2
but I can't to make mathematical operations with decimal like this
#y=3.2
#x=1.5
#let z=$y-$x
#echo $z
# 3
this... (2 Replies)
Hello all!
I used to use expr for doing simple mathematics, but has a main advantage and a main disadvantage:
The advantage is that it can take variables for numbers
(e.g.{1}: echo "Give me first"
read lol
echo "Give other"
read lil
sum=`expr $lol + $lil`
echo "The sum of $lol and $lil =... (5 Replies)

Only a few days after I coded this new feature from scratch, we are seeing over 3000 entries in the database from members (mostly guests) playing CS trivia.
I have spend a lot of time coding this (from scratch) and testing the API. From the logs, it seems to have an API bug which appears... (31 Replies)

elf64_getphdr
elf_getphdr(3E)elf_getphdr(3E)NAME
elf32_getphdr, elf32_newphdr, elf64_getphdr, elf64_newphdr - retrieve class-dependent program header table for elf32 and elf64 files,
respectively
SYNOPSIS
[flag... ] file... [library] ...
DESCRIPTION
For a 32-bit class file, returns a pointer to the program execution header table, if one is available for the ELF descriptor elf.
allocates a new table with count entries, regardless of whether one existed previously, and sets the bit for the table (see elf_flag(3E)).
Specifying a zero count deletes an existing table. Note this behavior differs from that of (see elf_getehdr(3E)), allowing a program to
replace or delete the program header table, changing its size if necessary.
If no program header table exists, the file is not a 32-bit class file, an error occurs, or elf is null, both functions return a null
pointer. Additionally, returns a null pointer if count is zero.
The table is an array of structures, each of which includes the following members.
The ELF header's member tells how many entries the program header table has (see elf_getehdr(3E)). A program may inspect this value to
determine the size of an existing table; automatically sets the member's value to count. If the program is building a new file, it is
responsible for creating the file's ELF header before creating the program header table.
For a 64-bit class file, returns a pointer to the program execution header table, if one is available for the ELF descriptor elf.
allocates a new table with count entries, regardless of whether one existed previously, and sets the bit for the table (see Specifying a
zero count deletes an existing table. Note this behavior differs from that of (see elf_getehdr(3E)), allowing a program to replace or
delete the program header table, changing its size if necessary.

The table is an array of structures, each of which includes the following members.
The ELF header's e_phnum member tells how many entries the program header table has (see elf_getehdr(3E)). A program may inspect this
value to determine the size of an existing table; automatically sets the member's value to count. If the program is building a new file,
it is responsible for creating the file's ELF header before creating the program header table.
