Good and bad news about NVIDIA and Linux drivers.

NVIDIA would be dropping pre-Fermi support and will be removing all support for graphics processors prior to the GeForce 400 "Fermi" series.
NVIDIA will support newly-dropped GPUs on Linux through 2019 , but also will come with support for new Linux kernels and X servers.
NVIDIA fixes for critical bugs, will be included in 304.* legacy releases through the end of 2017.
No further releases from the 71.86.* legacy driver series are planned.
The Linux 304.* legacy driver series is the last to support the NV4x and G7x GPUs and motherboard chipsets also support the G8x, G9x, and GT2xx GPUs, and motherboard chipsets based on them.
And this it's wonderful for linux users.

A major security problem with the Linux operating system.

If you read this article will see this can be one big issue. I try to find the bug under bugzilla. I think is already here and will be solve it. Also under lib/x509/verify.c in GnuTLS before 3.1.22 and 3.2.x before 3.2.12 does not properly handle unspecified errors when verifying X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers via a crafted certificate.

The GnuTLS is a secure communications library implementing the SSL, TLS and DTLS protocols and technologies around them:
It provides a simple C language application programming interface (API) to access the secure communications protocols as well as APIs to parse and write X.509, PKCS #12, OpenPGP and other required structures. It is aimed to be portable and efficient with focus on security and interoperability.
Updated gnutls packages that fix one security issue read more about this here.

Simple HTML5 script and google map.

Today I found one old html script ( few ages ago ). In the past I worked with html5 and this is simple example I make it.
The 'simple script and can be use with any features of google API.
About Google API you can learn more from developers google maps.
Let's see this script :
<html>
<head>

<style type="text/css">
  html { height: 100% }
  body { height: 100%; margin: 10px; padding: 10px }
  #map_canvas { height: 50% }
</style>
<script src="http://maps.google.com/maps/api/js?sensor=true" type="text/javascript">
</script>
<script type="text/javascript">
  function initialize() {
    var latlng = new google.maps.LatLng(33, 16);
    var myOptions = {
      zoom: 2,
      center: latlng,
      mapTypeId: google.maps.MapTypeId.TERRAIN 
    };
    var map = new google.maps.Map(document.getElementById("map_canvas"),
        myOptions);
  }

</script>
</head>
<body onload="initialize()">
  <div id="map_canvas" style="height: 50%; width: 100%;">

IPv6 versus IPv4

Linux users ...first sorry about this settings ...
I forced to make it under windows os because I don't know how to make it under Linux OS - so if you can deal with this then give me some help.
Now about windows users just follow the next issue...

So I set just IPv6 under pppoe internet provider connection.
I tested some web sites to see if is working well.
Next is working well ...
google.com
facebook.com
planet.fedoraproject.org
ipv6.br
... and also ipv6.rcs-rds.ro .
Also some softwares like NVidia Experience-update or Dropbox will not connect and will fail.
Can be one solution ? I think the answer is yes. But ...
Maybe I should study more about ...
Stateless IP/ICMP Translation (SIIT) translates between the packet header formats in IPv6 and IPv4. The SIIT method defines a class of IPv6 addresses called IPv4-translated addresses. They have the prefix ::ffff:0:0:0/96 and may be written as ::ffff:0:a.b.c.d, in which the IPv4 formatted address a.b.c.d refers to an "IPv6-enabled" node. The prefix was chosen to yield a zero-valued checksum to avoid changes to the transport protocol header checksum.[2] - Wikipedia
See the next image how can be set just IPv6 :
