I have moved from MS directX to OpenGL on Linux Debian. My computer is running Jessie version with Gimp. I am trying to use several of the gl 4.0 functions but getting compiler error. I check for OpenGL version and appears to be version 1.5 .... How can I verify the correct openGL version and how can I upgrade to a moder version of at least 4.0?

#include<stdio.h>

void init(){
const GLubyte* version = glGetString(GL_VERSION); // line 2338
printf("version = %s

...
The gcc compiler gives me:

I have the HD4850 and, I wanted to know if it is possible to use the CLI to see which version of OpenGL is the latest version I can use according to my driver. If it's not possible via the CLI then, what's the next best way? (I can't find a website for the radeon driver listing the latest OpenGL support per supported card).

xml=new XMLHttpRequest();

The verification does not return anything, cos my alert is not displayed at all.

I am interested in learning 3D programming. The thing is, I would hate to put too much effort to learn something that doesn't have future and is dying. My favorite language at the time is Java. My goal is professional programming.
So I have several questions:
1. Should I learn JOGL or start learning C++ and do C++ openGL programming?
2. Is there a big difference between JOGL and C++ openGL programming?
3. Is it worth to learn openGL? Does it have a future?
4. Is it a big difference between openGL and directX coding?
5. If choosing Java, then JOGL or LWJGL?
Why and what is the main difference between them?

I just bought a recently-released Toshiba CB35-B3340 Chromebook, and I'm trying to install Debian on it (I want to wipe out CrOS and give all harddrive space to Debian). However, I'm having problems booting from USB. When I press Ctrl+U at boot, the screen flashes back, the computer beeps, and I'm brought back to the same "OS Verification is Off" screen. If I press Ctrl+L to get to what is supposed to be the SeaBios screen, the computer beeps twice and nothing else happens.
I followed steps 1-4 and 8 of this guide: [URL] .... and I just downloaded the amd64 netinstall image from the Debian website and dd'd it to the USB stick.
I've tried two different USB sticks and successfully booted another computer from them, but neither work on the Chromebook. I've also tried both USB ports, since I've heard some Chromebooks can only boot from one, but to no avail.
I have looked into things like ChrUbuntu and crouton, but they look like they just set up a dual-boot or chroot system. I want neither of these, my goal being to have a normal Linux laptop at the end.
I upgraded my server yesterday via apt-get and my Perl scripts are not able to make HTTPS connections due to certificate verification problems.
This seems to be a problem for EVERY HTTPS site.
CURL gives the following error:
Code: Select allSSL certificate problem: unable to get local issuer certificate
I know that this has something to do with root certificate updates, but if I sound ignorant about it, it's because I am.
using CURL with the -k option allows the connection to be made.
I'm running OpenSSl 1.0.1k-3+deb8u2 on Jessie 8.2.
I would obviously prefer to not disable certificate verification on my server.

I just upgraded from FC8 (32-bit) to FC11 (64-bit). In doing so, I backed up my entire World of Warcraft folder so I could try to avoid having to download and install it all over again. However, I've now reinstalled wine (64-bit now), and the nvidia drivers from the rpmfusion repos (also 64-bit), and when I try to start WoW, it says it cannot load OpenGL. I'm wondering if anyone knows what's up, and if there's a solution that doesn't involve reinstalling WoW.
