I found this weird programming language that is an attempt to create the smallest possible compiler called brainf*ck, and i honestly want to try it but i don't have any knowlegde about how to compile the code.
Can you help me compiling a hello world program in brainf*ck?

I found a minimal compiler, surprisingly made by this guy in this repository.
I made this interpreter in like 40 minutes. It's under 70 lines of code and it only uses standard libraries in C.
it can be built by typing
make
you will get brainfuck.exe
i compiled this brainfuck code
cat.b
,[.,]
using
./brainfuck.exe cat.b

How can compile a chisel code? Which apps are you using? I tried to use Scala but, I got errors when I write a chisel code. Can you help me?
Chisel is scala code. You can compile it with a scala compiler -- scalac.
Usually, you use a build tool to do this for you, sbt.
You indicate the toolchain indicates there were errors when compiling your code. This is common. It's virtually unheard of to write code without errors in one go. The error should indicate what you did wrong.

I am new to Perl. I have created a Perl module(.pm). I am trying to make it executable. I wanna know is it possible to make Perl module executable or I am going wrong?
Thanks in advance.
Are you asking how to compile Perl code into machine instructions? There is no such tool. While Perl is compiled, it's compiled into high-level opcodes which require an interpreter to evaluate.

I'm currently working on an enhancement for a commercial utility that involves annotations with respect to LeadTools v13. In terms of LeadTools, it would appear that most things start off with the raster object, but without documentation for V13, it's somewhat of a challenge to make heads or tails of how to proceed in terms of reading the annotation files in.
If anyone has any code examples for such an old version, any help would be appreciated.
LEADTOOLS support don't have online documentation for this old version of LEADTOOLS. However, our help files shipped with the toolkit includes code examples for most of our functions including the annotations functions. You can find our help files in the following folder:

What is the difference between terms: "obsolete code" and "waste code"?
If there is the difference, what approaches are eligible for its reduction?
Obsolete code:
Code that may have been useful in the past, but is no longer used, e.g. code to use a deprecated protocol.
Waste code:
Never heard of the term, but I'd imagine - code that may or may not be executed that can be removed without changing workings of the application. I'd imagine this would include obsolete code.
Either of the above can range from single statements to entire libraries.
Personally I would say that obsolete code are methods that are there, but aren't used any more. Like for example deprecated methods/functions. Waste code would I define as code that has as only function to slow the application down.

I am a beginner in programming and I decided to take the Stanford online Intro to Programming Methodology course (cs106a). I followed the instructions and unzipped the Eclipse files onto my computer. When I tried to open it, it said "An error has occurred, see log file. " I am not sure how to fix this and I really want to learn this program. I searched other similar questions and only one was found and the suggested solution was to set environmental variables. Unfortunately, I don't know how to do that.
How can I get Eclipse running?
There could be numerous possibilities.
But first start with these.
(1) Are you using a 32 or 64 bit computer? Then you must use the Eclipse that is designed for your system.
(2) Do you have JDK installed? It's on Oracle website.
(3) Is your OS in good shape? As in did you or other programs mess around registry?
Hope this helps.
