Apple has been steadily positioning itself as the anti-Facebook for a while now, and between verbal jabs aimed at the social media giant and privacy-focused product decisions, the patient goodwill campaign seems to be working. Unfortunately, Apple isn’t going to save us, and now’s the time to keep your guard up. Continue reading Apple Isn’t Your Friend

Most people connect to the internet via their ISP’s DNS servers which more than likely are not the best and more than likely is slowing down your browsing. Using a 3rd party service not only speeds up your experience online. A while ago we wrote about OpenDNS, today we’re going over Google’s DNS service.
Google Public DNS IP addresses
IPv4 addresses are as follows:
IPv6 addresses are as follows:
Making the changes
- Start the
Network and Sharing Center(this process varies by windows version)

Use the following DNS server addresses
- Enter the IP’s from above
- Restart your computer
- Click the Apple menu ()

I will go over doing this in Ubuntu since that is one of the more common flavors.

- In the DNS servers field, enter the IP addresses, separated by a space:
- If you are prompted for a password or confirmation, type the password or provide confirmation.
If your distribution doesn’t use Network Manager, your DNS settings are specified in
sudo vi /etc/resolv.conf
If any nameserver lines appear, write down the IP addresses for future reference. Replace or add, the following lines:
nameserver 22.214.171.124 nameserver 126.96.36.199 nameserver 2001:4860:4860::8888 nameserver 2001:4860:4860::8844
Save and exit
Restart any Internet clients you are using.
sudo /etc/init.d/networking restart
Every router uses a different user interface for configuring DNS server settings; we provide only a generic procedure below. For more information, please consult your router documentation.
- In your browser, enter the IP address to access the router’s administration console.
- When prompted, enter the password to access network settings.
- Find the screen in which DNS server settings are specified.
- If there are IP addresses specified in the fields for the primary and seconday DNS servers, write them down for future reference.
- Replace those addresses with the IP addresses from above
- Save and exit.
- Restart your browser.
First Things First
First off, let’s talk about SSH keys and Security real briefly so that you can understand a bit more about what’s going on here and why it’s important. With all the issues happening in today’s digital age, everyone needs to start thinking about and taking one thing very seriously. You know, all the hacking and spying going on around us all.
One of the ways you can accomplish that is by using stronger encryption methods, in this case … SSH Keys or Public Key Cryptography. One of the major things is the key size. 1024 was common but that has long been hacked and not used anymore for websites and other public; so logically many are moving on to 2048 and even 4096, which is what I use.
SSH Keys provide a much more secure way to log into your servers than using passwords. While passwords can be easily broken by brute force attacks, SSH Keys way more difficult and if using a higher key can be almost impossible to decipher.
How does it work?
Generating a key pair provides you with a Private and a Public Key. You place the public key on a server you will connect to leaving the private key on your machine. When you SSH to your server you will not need to enter your password as your public key will be unlocked by your private key and you will be verified and allowed to get in.
