There is a short script in flatassembler that, i hope, explains windows icon format. Not bad thing, although *.ico files now become obsolete more and more. But obsolete not means unused :)

pixels fix 0x10 ; icon size
bpx fix 0x20 ; bits per pixel

sz_raw = $ - raw
sz_data = $ - idata

Here a small C example how to invoke Wake-On-Lan.

Algo is simple – broadcast UDP magic-packet.

Magic packet consists of:

1. Six 0xFF bytes
2. Target MAC address repeated sixteen times.

If, say, target MAC is 32:00:00:23:11:13. Magic packet is

FF FF FF FF FF FF 32 00 00 23 11 13 32 00 00 23 11 13 32 00 00 23 11 13
32 00 00 23 11 13 32 00 00 23 11 13 32 00 00 23 11 13 32 00 00 23 11 13
32 00 00 23 11 13 32 00 00 23 11 13 32 00 00 23 11 13 32 00 00 23 11 13
32 00 00 23 11 13 32 00 00 23 11 13 32 00 00 23 11 13 32 00 00 23 11 13
32 00 00 23 11 13

Ok, ive stop bugging you and here is the code:

    int i; int j;

    char * res = malloc(MAGIC_PACKET_SIZE);
    memset(res, 0xFF, MAGIC_PACKET_SIZE);

    for(i=1;i<17;i++)
    {
        for(j=0;j<6;j++)
        {
           res[i*6+j] = mac[j]; // expected to be at least 6 chars
        }
    }
    return res;
}

int main()

    WSADATA wsadata;

    char bc = '1'; // broadcast

        closesocket(sock);
        return 1;
    }

                     0,
                     (struct sockaddr_in *)&Sender_addr,
                     sizeof(Sender_addr));

He is the man, that can write good.

I’ve spent all my cash in restaurant, so road to home will be loooong.

Yes, i need a plan ot solve all problems. Enumerate it…  And the first step would be stop wruiting this post. Because it is a lazziness.

But it couldn’t stop me. Despite of wings absense on my bicycle :) Yes it was dirty and cold, in some places and moments. But i was feel warm on the road, because it was road to home.

And after this walk my bicycle does not need to be washed. The rain cleared it :)

Or you’ll reinvent Fisher-Yates shuffle algo only after you’ve wrote in your sources another bad algo, which has two cycles and undetermined time of execution. Like i’ve done this :)

What’s worng with this PCB? :)

But neary at 11:00am headache has become the past and i’ll move to my work. And it was not empty. I’ve found a breakdown which has searched in previous 3 weeks!

I’m a happy.

Hmm… What will be the next? May be smth. about TeX. Yep.
