Thanks for the replies Dougie and Enedil, I tried installing Mosquitto on the RPI2 model B and there's some dependency errors, apparently something called "squeeze" isn't supported? I think what I'm after is a kind of websocket. As Enedil suggested, a TCP websocket seems to be the easiest...

If a programming language is not the most popular one (like Java), it does not mean it is not popular at all.
Almost every programming language that runs flawlessly on Unix supports sockets.

The Ruby version may look simpler but: I presume that "puts" in Ruby hangs everything up until it has completed. A bit of a pain if you want to be doing other things at the same time. Correct me if I'm wrong. I don't see any possibility for error checking in that example. Not quite true -...

Certainly curl is a great tool that any one messing with web protocols should know about. Our poster did say "Preferably using ruby or javascript" though. Of course this can also be done easily in Python or Perl etc. Less easily in C/C++. I noted it. I think RheShaGan said it since (s)he ...

Use the power of Shell!
Curl comes to mind:

No need to write a wrapper code.

Get curl with apt:
sudo apt-get install curl

Just set up TCP sockets.

Why not using syslog?

Get GitHub Atom.

It is C#. It runs on .NET virtual machine. It doesn't contain CPU-specific code.

enedil

It doesn't matter. Since it is a web service, user can input fake data and you can't verify it.

Hi!

I just found that project:
http://artoo.io/documentation/platforms/raspberry-pi/
It's an easy way to write apps for devices (including Raspi) in Ruby. If you look at the bottom of the site, there are 2 links to similar frameworks for JavaScript and Go.

I meant https://github.com/joewalnes/websocketd

Use Websocketd. Easy to use, language-agnostic.

Generally, bad idea.

Learning straight X11 toolkit is time-consuming. Wayland is knocking Open Source's door.

Hey! C++ also has multithreading built-in.
Read the reference: http://en.cppreference.com/w/cpp/thread/thread

If you feel good with C++, take it as your programming language for this project.

What gives

Code: Select all

ls -l /usr/bin/sudo

To all you having problems with CygWin. Altrough it may be handy to get all stuff done on Windows, when interacting with Linux boxes, it's really easier to install a stand-alone Linux distribution on your laptop/desktop. And if you reall don't want to, grab VirtualBox , download something easy like ...

can i use wine for microsoft applications such auto run exe. I'm trying to use globe usb wireless tattoo broadband but won't work because the application was with the microsoft programs. No, you can't. Apparently, it was compiled for Intel processors. Raspi works on ARM. The other reason - you can'...

You can grab Firefox OS.

I don't know what are you using, but you should install package clang and run compiler

Code: Select all

clang++ file.cpp -o file

On Ubuntu and probably other distributions, there is a precompiled package containing toolchain for GNU/Linux ARM named gcc-arm-linux-gnueabi

Hi!

Check /var/log/apt/term.log.
Set different port for SSH.
Delete user pi.
Disable login via ssh for root.
Disable login via ssh for every user with sudo - use su to log in to those accounts.

enedil

Maybe shell script?

Code: Select all

#!/bin/sh
while ((1))
do
  python3 script.py
done
