Are you worried about your privacy and security on the Internet? Look at this collection of software to protect Date Posted:August 23, 2016 - 4:08 pm

Network Security

If you care about your privacy and security on the Internet, today we are going to provide a comprehensive compilation of different software tools to protect the most of your computer and your communications to show what does a cryptographer do. This compilation will arrange for different categories such as web browsers, disk encryption, authentication, encryption of communications etc.

The tools below will show you are completely free, and many of them are open source so anyone can audit them to ensure their safety.

web browsers

The recommended way to protect your privacy web browser Mozilla Firefox , a browser that has a large market share. This browser does not send information to third parties, and also allows you to configure the detail levels privacy by preventing third – party cookies among many other options. However, to further protect our navigation, we recommend some extensions that are compatible with Firefox:

  • HTTPS Everywhere
  • NoScript
  • Privacy Badger
  • Random Agent Spoofer
  • Origin uBlock

Other recommended web browsers is Tor Browser uses the Tor network to anonymize our navigation and is based on Firefox but incorporates a specific configuration to use the Tor network.

web searchers

The web browser that provides privacy and security is DuckDuckGo even able to use the Google search engine itself without leaving any trace that we have been those who have done the search. In fact it has very interesting features such as search Bitcoins purses and calculating hashes of passwords . Nor should we forget that has browser for Android .

Email Clients

One of the customers more secure email is Mozilla Thunderbird , a software that allows us to configure any mail service with POP3, IMAP and SMTP, supports PGP encryption through an extension to protect our point to point communications. Thus, if we send an email with our typical Gmail account, Google can not read the contents of the email. If you want to add an extra security, you can set you the Torbirdy extension to email the Tor network trip to the addressee.

Clients chats

It is difficult to recommend a way to chat safely without much complicate life. Although WhatsApp has recently added to – end security in their software, and also have this security Telegram point to point, all messages pass through their servers so you may end up being tracked in some way. Telegram exist in secret chats that do not pass through their servers. An alternative is to use the popular Pidgin with extensions Telegram for example, and use your platform for our insurance chats, also can always install Pidgin extensions to encrypt the content ourselves.

Disk encryption software and data

If you use Windows systems you can encrypt entire hard drives with encryption software Microsoft, own Bitlocker . If you do not trust this solution from Microsoft, you can always use the name Veracrypt to encrypt your disks or to create encrypted inside which stores confidential information containers. If you use any type Debian Linux, you can use LUKS to encrypt your hard drive completely, do not forget not to put the Grub password to further protect your system. You can also use eCryptfs to encrypt disks or directories.

Password Manager

Although there are many password managers currently supported including synchronization between different devices such as LastPass, we are going to recommend you Keepass that uses a local database encrypted with 256 – bit AES, is open source and completely free.

Remote control software

The best way to manage remote computers is with SSH whenever possible, and authentication using public key cryptography, with no user name and password. If we manage through the graphical interface, use an SSH or VPN tunnel configured properly and the typical VNC to only accept connections on the LAN is also a very safe option, it is advisable to dispense with cloud services like TeamViewer recently has had security problems.

secure operating system

Currently one of the most secure operating systems is Tails , is set by default with all security options and maximum privacy. It is based on the popular Debian Linux distribution, and all Internet traffic travels through Tor that is already configured by default.

Finally, another recommendation of privacy and security is to use good passwords in your services and not repeat between different services, and enables two – step authentication whenever possible, use this website to find out if a particular service supports authentication two factors.

Software Wars: A film about the open source philosophy Date Posted:August 18, 2016 - 7:33 pm

Software Wars: A film about the open source philosophy

In the age in which we live, there are many technological advances and these work largely through the use of software, however, often these advances pose obstacles in their development because of the control exercised by the companies that develop. This is the main plot of the movie Software Wars  that seeks to inform the geeks and the general public about the importance of the use of Free Software and the benefits it gives us both users and developers. You can see full movie on putlocker movies.


More than a film, is a documentary based on one part of the book called “After the Software Wars ” (available free and highly recommended) who wrote Keith Curtis (the main producer). He spent 11 years at Microsoftuntil he decided to adopt the philosophy of Free Software, so he knows what it is to work on both sides: In the free software and proprietary.

The way in which the project is being funded through crowdfunding onIndiegogo and the goal to develop the project is 150,000 USD. The documentary is interesting for the way in which the issue with information and interviews with the likes of Linus Torvalds, Jono Bacon, Greg Kroah-Hartman and Guy Martin is addressed. To name a few.

Release date (if you reach the goal of $ 150,000 USD) would be scheduled for June 2013 and the distribution of the documentary will be both digital and physical. It seems a good initiative to encourage the community to become more involved projects open source software also involve average users to learn about the benefits of adopting this philosophy.

Those involved in the project and describe the documentary:

Software Wars is a film about the battle of our rights to share our ideas about technology. The software will not be owned by companies such as Microsoft, Apple and Google that impede technological progress.

A clear example of the approach to the problem is the use of custom and assistants as does Google Now or Siri searches. Both are not open to other developers to contribute more features to help us in everyday life, everything is controlled by Google or Apple and they decide to include and what not.

Software Wars will have to be on your list of movies “Geek” to see in 2013, no doubt.

Finally, we'll have a *fantastic* mystery discussion coming up - but you have to be there to find out.

Good news, bad news...
Posted by: form1 on Sunday, February 29, 2004 - 04:53 PM

Bad news: no meeting tommorow night (the first). I apologize for that - I just got back from Mexico and didn't get the ball rolling until too late.

Good news: Fantastic meeting scheduled for next week - Gaim, Firebird, TWiki, and the Centralug portal. Look out for a record attendance.
