From food forests to healthy soil. 5 Incredible permaculture videos.
When I posted 7 no-cost ways to grow more food from your veggie garden, one commenter argued that mulching was not a good strategy—suggesting that gardeners should plant polycultures instead, following the principles of permaculture.
While I'd dispute the idea that there is one "right" way of gardening, or that mulching and polycultures, or mulching and permaculture for that matter, are mutually exclusive, I do agree on one matter. Understanding permaculture design—which can loosely be described as a design discipline informed by principles observed in nature—can definitely make you a better gardener.
We've posted a fair few videos on permaculture and permaculture-inspired gardening over the years. I thought I'd round up a few of our favorites.

2000 year old food forest feeds 800 farmers
Permaculture is often thought of as a new-fangled, hippy thing. And yet most of its principles and practices are borrowed from traditional agriculture around the world. Food forests and polycultures are nothing new. This food forest in Morocco, for example, features an overstorey of date palms to an understorey of olives, bananas, dates, grapes, guava, mulberries, carob and tamarind. And much of your coffee, assuming you buy shade grown, organic and Fair Trade from small farmers, will most likely have been grown in some form of forest-inspired polyculture.A tour of a modern permaculture food forest
The Central Rocky Mountain Permaculture Institute has been pioneering permaculture for decades. Here we tour a 20 year old food forest and look at what's succeeded and why. Grab a pen and paper and start taking notes.An incredible permaculture allotment
I learned much of what I know about permaculture from the inimitable Mike Feingold. Here he gives us a tour of his productive, diverse allotment in inner city Bristol. Don't let the chaotic appearance of the plot fool you—Mike grows a ridiculous amount of food on this plot, and shares it abundantly. (Mike's vodka-soaked black currants are a particular treat.)A permaculture approach to healthy soils
It's easy to focus on the above ground action when it comes to permaculture. What plants go where? How do you cultuvate them etc? But what's going on under the ground is so much more important. Each teaspoon of healthy soil contains millions of microorganisms. Permaculture pioneer Geoff Lawton knows a thing or two about how to take care of them. (He even created a whole documentary all about soil.)Sunday, June 30, 2013
Bugging Brussels: New Snowden leak claims NSA spies on EU diplomats
Even more scathing reports of US surveillance are emerging from Germany – courtesy of Edward Snowden. Der Spiegel magazine is reporting that they’ve seen a top secret US document – outlining how the country’s intelligence bugged EU offices and spied on the bloc’s internal computer networks. RT’s Peter Oliver is in Berlin with more on this latest leak. RT is also joined by Lode Vanoost – former deputy speaker of the Belgian parliament.
Government report reveals encryption actually thwarted wiretaps for the first time on record
According to an official U.S. government report, four wiretaps have been thwarted by encryption, something which has never happened since such records have been collected.
This comes after as it was revealed that the National Security Agency’s massive surveillance program even spied on European diplomats. Meanwhile, the Army has blocked the Guardian over security concerns related to the information being put out about the surveillance program.
This latest revelation came in a report from the U.S. Administrative Office of the Courts, the agency that oversees federal courts.
“Encryption was reported for 15 wiretaps in 2012 and for 7 wiretaps conducted during previous years,” the report states, highlighting the fact that more people are turning to encryption over privacy concerns.
“In four of these wiretaps, officials were unable to decipher the plain text of the messages,” the report continues. “This is the first time that jurisdictions have reported that encryption prevented officials from obtaining the plain text of the communications since the AO began collecting encryption data in 2001.”
It’s important to note that the numbers mentioned above are quite tiny when compared to the total number of wiretaps authorized by federal or state judges.
The office’s 2012 Wiretap Report states that there were 3,395 authorized wiretaps, a quite notable increase over the 2,732 authorized wiretaps reported in 2011, as Wired’s Threat Level points out.
It’s quite important to note that this figure does not include any of the wiretaps authorized by the Foreign Intelligence Surveillance Court.
That is something that must be noted because the highly secretive Foreign Intelligence Surveillance Court is the body which authorized the collection of all U.S. records from Verizon.
The latest controversies about government surveillance don’t deal with these types of wiretaps authorized by court order, instead they deal with the wiretaps authorized under the Foreign Intelligence Surveillance Act (FISA) and related legislation which is subject to secret government interpretations.
Interestingly, this year’s report points out that a whopping 97 percent of the wiretaps issued in 2012 were for “portable devices” like mobile phones. Other equipment targeted by the wiretaps include everything from landline phones to computers to fax machines to microphones.
Around 87 percent of the wiretaps were issued in drug-related cases, according to the report.
David Kravets, writing for Wired, points out that in 1997 Louis Freeh, who was the director of the FBI at the time, told Congress that “all of law enforcement is also in total agreement on one aspect of encryption. The widespread use of uncrackable encryption will devastate our ability to fight crime and prevent terrorism.”
Despite the dire warnings that were used to attempt to get legislation passed that would authorize a government backdoor into almost all electronic communications at the time, this hasn’t happened.
“Sixteen years later, and judging by the government’s own accounting, we’re not even close to Freeh’s fears becoming reality, despite the government’s continued push for a backdoor into virtually everything,” Kravets writes.
Indeed, despite government fearmongering leveraged in a clear attempt to justify a further erosion of privacy and a further undermining of Constitutional rights, the fact is that encryption hasn’t created a climate where terrorists and criminals are somehow untouchable.
Yet this latest report does show that for people who do care about privacy, it might be possible to keep your communications private.

3 Ways Facebook Hackers Target Your Account
Facebook accounts are an often overlooked gateway into an individual’s personal life. We, as social networking users, have few reservations about posting our photos, location, plans to travel, private outbursts, and information regarding friends, family and work. We include names, phone numbers, email addresses, GPS coordinates and the list goes on and on. But you ask “What’s to worry? After all, I am only posting this information for friends and family to see, right?”. The simple answer is no. Facebook hackers want your information.
The truth is that many of your friends’ and family’s accounts are being hacked every day. By successfully compromising your Facebook account an attacker has unlimited access to a wealth of information about you, your friends and your family. In addition, if a hacker gets your Facebook password, I think it’s reasonable to assume that he could then take over your email accounts, bank accounts, and other private information as well. The following 3 Methods of Facebook Hacking are something that everyone should make themselves aware of. When you have learned the attacker’s methods you can begin to protect the information that you so freely give out on the internet.
1. Social Engineering:
Generally the first thing a hacker will do is to find a way directly to your inner circle. One way an attacker might start is by ”friending” some of your closest friends, family and coworkers on Facebook. Once enough mutual “friends” are built up, they will eventually work their way up to sending you a friend request. It may appear to come from a name that you know, or perhaps some curious account with a hot profile picture to grab your attention. Either way, you look at all of your mutual friends and you click “Confirm” on the friend request, allowing the attacker access to a gold mine of information.Once the attacker is on your “friends” list he can see all of your photos, friends and family that you talk to the most, your daily activities and more. In addition, he may be able to access your email address, phone number, the schools you went to, and where you currently work.
Armed with this information the hacker can now move on to the next level of attack, attempting to access your login details and other private information.The lesson to be learned here is “Don’t accept friends requests unless you’re darned sure you actually know the person on the other end”. Either confirm the friend request by phone, by sending a private Facebook message asking for some specific details, or by only adding friends where you have initiated the friend request.
2. Brute Force:
Once the hacker has gained access to the names of your cats and dogs, children’s names, birthdays, etc he will begin the process to brute force your Facebook password. This means he will make repeated attempts to log in to your account using a list of words and variations taken from the information you post to your account. If the information gleaned from your profile, posts and photos does not yield a hit, he will move on using automated applications and dictionary files to attempt to crack the password. There are a bunch of tools that claim to do this automatically, one only has to perform a quick Google search to find a page full of options.
A potential user of brute force applications can find unlimited tutorials on sites like YouTube. With the availability of tools like this, I suspect anyone with a keyboard has the potential to get your password if you aren’t careful. However, if you use long passwords, consisting of numbers, upper and lower case letters plus a special character (e.g.- %,$,!,@), I think you should be a bit safer from these brute force types of attacks.
3. Phishing:
According to Wikipedia, “Phishing is attempting to acquire information (and sometimes, indirectly, money) such as usernames, passwords, and credit card details by masquerading as a trustworthy entity in an electronic communication. Communications purporting to be from popular social web sites, auction sites, online payment processors or IT administrators are commonly used to lure the unsuspecting public.”In layman terms this means phishing is the act of a hacker creating a clone of a well known website login page, such as Facebook or your bank, with the hopes of tricking you into inputting your username and password on the page. Once you type your information into the login form, and click the submit button, your name and password are added to a database or sent to a fake email address controlled by the hacker.
A hacker can use any of several methods to grab your Facebook information through phishing techniques. The easiest way is to create a fake Facebook login page, put it on a free hosting service and then send you an email or Facebook post with a link to the page. The problem with this method is the fact that the domain name in the link and your browser address bar should be a dead giveaway as shown in the image above.
Another, more popular method is to use a technique called “tab nabbing“. Tab nabbing is an exploit where an attacker sends you a link to a regular looking web page such as a game or a video. When you switch to another tab in your browser, the original page does a quick refresh to a fake Facebook, bank or email login page. The tab-nabbing exploit takes advantage of user trust and inattention to detail in regard to tabs. Many internet users don’t bother to look at the URL of a tab they’ve already been on. Here is a video example showing how a simple tab-nabbing attack works.
When attempting to compromise the account of a more experienced internet user, hackers may utilize a combination of tools for a more sophisticated attack. Some of these tools include ettercap and the Social Engineer Toolkit’s Credential Harvester. With this type of attack the hacker can manipulate your DNS configuration, the service that translates domain names to IP addresses. Once your DNS has been changed all of your internet requests to www.facebook.com will go to a server under the attacker’s control. This type of attack is very difficult to identify because the actual domain name Facebook.com will appear in your internet browser address bar.
6 Simple Steps To Keep Your Account Safe:
- When logging in to your Facebook account, always double check the URL in your browser’s address bar
- Use long, complicated passwords that utilize upper and lower case letters, numbers, and special characters
- Do not post personal information to your Facebook profile (e.g.- phone numbers, email address, etc)
- Review and adjust your privacy settings, in both your browser and your Facebook account, on a regular basis
- Only allow people on your “Friends” list that you have personally sent a friend request to, do not accept blind requests!
- If you do accept a friend request from someone, make certain that you have verified the person on the other end using some other means.
The internet brings convenience, business growth, and the opportunity to share your thoughts and memories with friends and family. It also allows an attacker unlimited access to your life and private information. By following a few simple guidelines, you can keep yourself a bit safer on social networking sites like Facebook.com:
Evade Government Surveillance Stay Anonymous Online
Why stay anonymous online? In today’s society there are people and automated devices that are recording your deepest, most private thoughts and activities. Each day we voluntarily divulge the most intimate details of our lives through social networking accounts, email, banking apps, online games and more. In addition, governments and corporations can censor and block our traffic based on whatever standards are in place that day.
Government agencies, hackers and sophisticated bot networks are capturing every piece of digital data that we transmit through all of our internet-connected gadgets. Smartphones, Smart TVs, computers, tablets, and so much more…they are all vulnerable, nothing is safe these days. Even your old clam shell phone isn’t safe. This is because many phone providers route your calls over media using the Internet Protocol at some point within their network. For example, long distance providers transfer calls over VoIP all the time.
Whether you’re browsing the web, signing up for a new online game, or simply checking your email, you are constantly leaving tracks and giving away information to anyone with access and the knowledge to analyze the traffic. Once the data is compiled the attacker can build an incredibly accurate profile of not only your online life but your real-world life as well.
I know, most people say, “Why would hackers want to hack into my life? I am not that important” You have to understand that these “intruders into our lives” are scanning huge blocks of internet addresses at a time. They don’t care who you are. Your computer is simply another target IP address as they scan through thousands of computers and devices in their search for more information. Once collected they take all the information and funnel it into databases where they can search through it later for high valued loot.
Don’t believe me? Just read the following two stories about what our own government does:
NSA Utah Data Center Largest Spy Compound Ever – Part 1
NSA Utah Data Center Largest Spy Compound Ever – Part 2
So, the big question is, how can you stay anonymous online? Free from government censorship and potential eavesdropping from some hacker or three-letter government agency that wants to invade your privacy while you use your computer. In comes Whonix, the Anonymous Operating System!
Use Whonix, The Anonymous Operating System, Stay Anonymous Online
Whonix is a free, general purpose computer operating system based on Virtual Box, Linux and Tor. The purpose of Whonix is to allow internet users the ability to stay anonymous online. This is most beneficial to users in regimes that censor and monitor access to the Internet, but it can also be used by anyone who values their privacy or doesn’t want their activities tracked online.
By design, IP address leaks are meant to be impossible while using Whonix. The developers claim even malware with admin privileges can’t find the Whonix Workstation’s real IP address or location. This is because Whonix consists of two (virtual) computers. One machine acts as a gateway or router and runs only Tor, a sophisticated anonymity software. This machine is called the Whonix-Gateway. The other machine, which called the Whonix-Workstation, is on a completely isolated network that only allows internet connections to be routed through the Whonix-Gateway.
Tor, the technology on which Whonix is built, is a free software, along with an open network consisting of thousands of computers located around the world. Together they strive to provide anonymity for individuals accessing the Internet. The Tor Project helps you defend against a form of network surveillance, known as traffic analysis, that threatens everyone’s personal freedom and privacy.
Tor helps to reduce the risks of both simple and advanced traffic analysis by distributing your internet requests over several places on the Internet, so no single point can link you to your destination. The idea is similar to using a hard-to-follow series of roads while driving in order to throw off somebody who is tailing you.
Whonix automatically sets up an isolated network environment where your virtual “Workstation” can perform all normal internet related tasks such as checking email, browsing web sites, blogging, connecting to corporate VPNs, etc. However all of that outbound traffic is then routed in such a way that it can only pass through your virtual “Gateway”, which encrypts the packets and sends them over several hops on the Tor network prior to landing at their final destination.
Once your traffic leaves the Whonix Gateway it is routed directly through the Tor network. Instead of taking a direct route from source to destination, data packets on the Tor network take a random path through several relays, so no observer at any single point can tell where the data came from or where it’s going. The relays even take additional steps to erase your tracks periodically along the way.
In the event that the Workstation user initiates a request to a new website or internet resource, the Gateway simply selects an alternate path through the Tor network as seen in Figure 3.
There a bit of a caveat to this system however. As indicated by the red dotted-lines in the images above, the last hop in the Tor network passes the traffic in the clear to the final destination. One of the primary functions of this computer, as an exit node, is to decrypt the data packets before they are passed off to their final destination. This means this exit node could be vulnerable to a man-in-the-middle attack, or it could have even been placed there for the specific purpose of monitoring exit traffic by a hacker or government agency. While the exit node would still have no information regarding the IP address or location of the original Workstation user, it would know the type of internet request that they sent to the destination server.
This scenario can be averted by using SSH tunnels or a VPN on top of the Tor network. One would only have to install the appropriate software on the Whonix Workstation in order to provide an end-to-end encryption solution for the traffic. Another method to bypass the man-in-the-middle scenario would be to employ the use of Tor Private Bridges or Private Exit Nodes.
It is important to note however that Whonix can be effectively used by most people right out of the box for web browsing, blogging and private conversations.
In order to make use of Whonix you will need to download a free copy of VirtualBox from the link below:
https://www.virtualbox.org/wiki/Downloads
Once VirtualBox has been downloaded and installed you can download the Whonix-Workstation and the Whonix-Gateway packages from SourceForge:
http://sourceforge.net/projects/whonix/files/whonix-0.4.5/
Once downloaded, just import the machine files into VirtualBox as-is and start them up, you don’t need to change any settings…also be sure to start the Whonix-Gateway machine before firing up the Workstation image.
The default login credentials for both virtual machines are as follows:
====================
Username: user
Password: changeme
Username: root
Password: changeme
====================
Once the images have completed the boot process you can login and run the “whonixcheck” command from the CLI (command line interface) in order to verify proper connectivity to the Tor network. The Workstation output should look similar to the following (click image to enlarge):
