Gtk native file chooser dialog now gets thumbnail and icon views based on the recent merge request in the gtk main branch.

Tries LXLE yesterday and found it is very good, I mean good for me.
I need help. Tried to register to LXLE forum. They asked me for the reason registering at LXLE forum. My answer was: Learn Linux. I was denied. I do not know whether I am allowed to ask questions about LXLE here ?

Just tries LXLE and found it very good, I good for me. I intend to use it. Have to find a forum to help me on many questions regarding to LXLE. It is not listed here under Linux sub-forums. Is it not Linux?

Thanks

Far2l is a port of the Windows text-based file manager Far. And to be clear, that's a lower-case L (as in "Linux") not a number 1. It runs in the terminal and is designed around a plug-in structure, enabling compatibility with SSH, WebDAV, NFS, and more. You can compile and run far2l on Linux, Mac, and BSD, or Far on Windows.

I have set up samba on my Ubuntu 22.04 server. I'm trying to connect to it from a Win 7 computer, but I get these errors in /var/log/samba:

Hi,

I am taking the Harvard CS50 online course. The programme is to check credit card number validity.

Why does the checkfunction() fail with a floating point error, when tested with a valid Mastercard number?

I also tried using gdb, but it gave an error to do with get_long being not declared.

Any other comments on how to improve the code very welcome.

NB. I'm not sure if the maths works yet...

Code: #include <cs50.h>
#include <stdio.h>

 // x is the input
long x;
 // y is the calculated checksum
int y = 0;
 // i is an integer for calculations
int i = 1;

// Function to loop through the digits of the card number, beginning with the last digit. See HP Luhm algorithm for further details
int checkfunction(void)
{
    printf("made it here also\n");
    //
    for (i = i + 0; i <= x; i *= 1e2)
            {
                //  Divide the number by a multiple of 10 and take the remainder. Multiply the digit by 2 and add to the checksum.
                int z;
                z = x % 10;
                if (z <= 4)
                {
                    y = z * 2 + y;
                }
                // If the product would be >10, add each digit of the product separately to the checksum
                else if (z >= 6)
                {
                    y = ( z * 2 ) - 10 + 1 + y;
                }
                // Add the next digit along (from right to left)
                y = (x % (i * 10)) + y;

            }
    return y;
}

int main(void)
{

    x = get_long("Number: ");

    // Exclude numbers shorter than 13 digits, longer than 16 digits, or that are 14 digits
    if (x < 1e12 || x > 1e16 - 1 || (x >= 1e13 && x <= 1e14))

Had CentOS running KVM/QEMU, had sound in both Linux and Windows VMs.
Just standard build/installed the main system, and the VMs, the builds saw what I had and just did the right thing(s).

Couple of years ago, replaced with better machine, loads of memory, good quality components etc., went with openSuSE LEAP 15.2

WkStation VM, also openSUSE 15.2, no audio in Firefox or social media, etc.

Messed with it some, no avail, finally just lived with it and sent things I wanted to see & hear to my iMac. Upgraded to 15.3 maybe two years ago, hoped it'd fix itself, it did not, I didn't mess with it.

Just upgraded to openSusE LEAP 15.4, saw some interesting things and thought I'd try it again. And again, nothing I'm finding in the web-searches and the forums is moving this along.

I'm listening to Internet radio at the top-level (Server: openSuse-LEAP 15.4), but no audio in VM (openSuse-LEAP 15.4) -- testing with uTube.

Long standing problem. Where do I begin?
