On the 21 of December Linux Mint 14 Xfce has been released, codename Nadia.
This release of Mint is based on Ubuntu 12.10 and shipped with the XFCE desktop environemnt as my readers probably know I’ve installed Mint 13 XFCE on my new desktop and so I’ve decided to upgrade my installation to this new release.

As first thing, do I suggest to upgrade to this release ?
Yes and no, Mint 13 is based on Ubuntu 12.04 that is a Long Term Support distribution, this means that like other LTS releases 12.04 will have updates for 3 years, and will include point releases that bundle updates to shorten downloads for users installing the release later in its lifecycle. The point releases and dates are: 12.04.1 (23 August 2012), 12.04.2 (31 January 2013), 12.04.3 (15 August 2013) and 12.04.4 (24 January 2014). There are no further point releases scheduled after the release of Ubuntu 14.04 LTS.

So if you are happy with your software and all your hardware works you have no strong reasons to do this.

On the other hand, if like me you have a D-LINK N 150 aka DWA-125 or some other hardware that don’t work perfectly with your Kernel an update could help you, spoiler: This upgrade helped me in removing all the proprietary drivers in my installation.

The traceroute tool is available on practically all Unix-like operating systems. Variants with similar functionality are also available, such as tracepath on modern Linux installations and tracert on Microsoft Windows operating systems. Windows NT-based operating systems also provide PathPing, which provides similar functionality.

google dnsIn recent years we heard most often about using alternate DNS to those provided by your ISP.

But why not use your ISP’s DNS in theory it should be as fast as possible since there are fewer network hops to reach it, but the alternate DNS, provide additional services (such domains are known to report scams) are redundant worldwide and therefore offer greater stability.

opendns

Among the many DNS providers the best known are undoubtedly Opendns and Google Dns, the first is historically the market leader, offers additional services for a fee or the possibility of using their DNS servers for free, for some years I’ve used  with satisfaction this service.

Local dns-cache for faster browsing

A DNS server resolves domain names into IP addresses. So when you request “google.com” for example, the DNS server finds out the address for the domain, and sends your request the right way. You can run a DNS cache on your computer. This will speed up the process of looking up domain names when browsing. [...]
