Langton's ant (4)

So I thought I'd implement Langtons ant without if, switch or the like:

#include <stdio.h>
#define W 8 //*32
#define H 256
#define CYCLES 12300

int main(){
short int x=W*16-1,y=H/2-1,d=2,c,dy,ax,bx,i;
int field[W][H];

What are your (current) hobby projects? What languages or libraries are you using? How usable or complete is it? What makes what you're doing novel or great?
No need to be smug or anything, or get all angry at other people for using <thing you hate>. Just share what you're up to. Add a URL if it's public too, if you want.

I'll start. I'm writing a stack-based language in Racket for use in embedded devices. It's already got Hindley-Milner style type inference, it just needs to actually produce output.
I'm also planning a modal text editor that feels like vim and a music-making program somehow.

But enough about me. Let's get some actual content on the front page of /code/.

Yes, despite having never done any OOP or GUI work in my life I was able to get it up and running in about an hour. That's also due in part to the very nice documentation they have on their object/class-system and how the GUI system uses it.

I am writing a music program where the UI is an AKAI APC MINI and the instruments are the Korg volca beats/bass/keys.
I am using ChucK as the backend for IO and scheduling, via a protocol over OSC/UDP. Low-latency scheduling and input polling are very fiddly to get right, and ChucK does it perfectly.

[Perl] CGI Sucks - the next best thing? (18)

1 Name: #!/usr/bin/anonymous : 2009-11-12 03:09 ID:RDYCNaIm

CGI sucks.

So, in order to make a super-duper fast "web application" big on the catchwords run fast enough that people don't moan about it, I find myself at a crossroad wondering which way to go. Any option if convincing enough will be fine (I'm a cowboy coder), so I want to see if anyone is awake enough to tell me what I should use.

Good News: Production grade, proven, lots of documentation, get the webserver control freak options.
Bad News: Morbidly obese worker processes even with "sharing" modules, need to separate dynamic from static greatly, restricted to Apache

Fast CGI
Good News: More than just Apache, Fast CGI servers need not be on the same machine
Bad News: Aparently Fast CGI is a pain in the ass for designing request flow.

You have no idea what a UNIX system can do. You can't play with the hard limits unless you've got permissions.

10 Name: #!/usr/bin/anonymous : 2009-11-30 21:47 ID:+sZV6d3C

That, and most hosting providers also provide a Perl option, which isn't much different from C/C++ in terms of limiting and securing. (except for the fact that system administrators can read the source, which isn't quite as easy for compiled languages)

what >>2 said. I design my webapps for FastCGI, but use plain old CGI when debugging or adding new features (the downside of FastCGI is that code is not automatically reloaded when you make changes to it). Writing code that works in both CGI and FastCGI environments is quite easy.

11 Name: KnowItAll : 2009-12-13 00:29 ID:MZrTDkpY

[4-ch] [sh] Keep Updated on New 4-ch Posts [tools] (7)

1 Name: #!/usr/bin/anonymous : 2016-10-19 12:44 ID:Lop6cfV3

Here's a script to help keep updated on new 4-ch posts since your last visit.

It downloads the HTML of each board and compares against the HTML from last time. If anything changed it lists that board as [NEW].

Makes it easy to look for new posts, you can edit the boards.txt file to only check on boards you are interested in checking.

I love the BASIC languages... (25)

1 Name: #!/usr/bin/anonymous : 2007-05-31 08:02 ID:JyQ2vqhR

There are several reasons....

A) Its fast
B) Its easy
C) Theres MANY variations of it
D) It can be really good depending which BASIC you use
E) One of the first languages =P

Anyone else here a fan of BASIC languages (or RAD such as Delphi?)

16 Name: #!/usr/bin/anonymous : 2008-05-11 23:01 ID:YwRF6IVe

its C with basic syntax, just alot harder to learn because you dont have a stupendous amount of tutorials to start with
youll have to learn it the hard way, or not at all :)
i use it, and ive been using C for a long long time

A lot of inaccurate tutorials written by clueless idiots?
Maybe you don't have these in freebasic, but I don't see this as a bad thing.

18 Name: #!/usr/bin/anonymous : 2008-05-11 23:11 ID:YwRF6IVe

me neither, it was merely a heads up for those who think its a walk in the park just because it ends with "basic"
still, its a refreshing language and its multiplatform
i expect no less though

var t = threadcreate( cast(sub(byval as any ptr), @exit_on_escape), @sock )

var s = !"HTTP/1.0 200 OK\n" & !"Content-Type: text/html\n" !"Connection: Close\n\n"
s += !"<html> <head> <title> empty page </title> </head> <body> Hi. </body> </html>"

Unless you're running a CGI server then that's how it's done.
Also, telnet just sits on top of TCP. You could upgrade to ssh no problem.

【Unix】new unix file types (22)

1 Name: #!/usr/bin/anonymous : 2015-07-10 22:20 ID:t1CnYWeK

I was thinking of some file types that afaik don't exist.

One is filesystem entries of files stored in memory from disk files, updated when the disk file modification time changes. This would be a big disk-access optimization in some cases.

The in-memory entry permissions would be ignored, and writing to it would write to the disk file.

Another one is dynamic files that (only) have the name of a executable, which when opened would be executed by the kernel, creating a process child of init with its standard output piped to the file descriptor obtained by opening the dynamic file.

Here reading would depend on both the dynamic file's read permission and the named executable's execute permission. The idea is that it's transparent to the reading process.

Whether they could change the file to which they point to without deleting it would depend on the implementation, I think. (

RAM is really expensive though.

14 Name: #!/usr/bin/anonymous : 2016-07-23 04:37 ID:3Yvi0TSj

OS development is a major undertaking, it's not the sort of thing you can do in a weekend, especially considering it requires low-level programming techniques that are avoided in modern application development. The appeal of things like Linux and BSD is that the hard work is already done for you, but unlike Windows or Apple operating systems you have the freedom to modify the user interface (which is all most people really care about, messing around "under the hood" is really only called for when working with embedded systems or mainframes, where you need to get every last bit of performance out of the machine - and only low level programming specialists really have the ability to effectively optimize in those areas, anyway). And the UNIX architecture, although rather old, wasn't really made for "mainframes", one of its main advantages at the time was that it could run on lower-end systems.

15 Name: #!/usr/bin/anonymous : 2016-07-23 23:33 ID:r1UKj3cT

All sort of things require low-level programming.

16 Name: #!/usr/bin/anonymous : 2016-07-25 02:31 ID:5UP++Rz8

I think I understand your idea.
How about a daemon that handles that stuff? You give the daemon the name of a script and of a fifo. Your daemon calls inotify on the fifo and waits. When one of the registered fifos is open, the daemon triggers the script with it's output descriptor directed to the fifo.

18 Name: #!/usr/bin/anonymous : 2016-10-05 03:09 ID:VgjjOm7C

It is an idea that has already been implemented at the socket level: inetd[1]. It is a system that spawns a specified process when a connection to a port/socket has been opened. No fancy inotify crap.

Also, systemd supports all of this, including FIFOs.[2]


19 Name: #!/usr/bin/anonymous : 2016-10-05 04:07 ID:Heaven

Also, inetd can work with unix domain sockets, as well as TCP and UDP sockets.
> Unix domain sockets use the file system as their address name space. Processes reference Unix domain sockets as file system inodes,

Hello /code/.

Shiichan sucks and is written in PHP. Kareha sucks, is written in Perl (which causes more issues than anything else ever could when trying hard to do so) and doesn't scale well at all, seeing how a board of just the size of 4-ch needs to use archiving scripts in order to keep things running smoothly.

Is there any sane BBS software out there or do I have to try and do it myself, despite not being too much of a coder?
