Vidalia aims to defend against traffic analysis, a form of network surveillance that threatens personal anonymity and privacy, confidential business activities and relationships, and state security. Communications are bounced around a distributed network of servers called onion routers, protecting you from websites that build profiles of your interests, local eavesdroppers that read your data or learn what sites you visit, and even the onion routers themselves.
Vidalia\’s security is improved as its user base grows and as more people volunteer to run servers. Please consider volunteering your time or volunteering your bandwidth. And remember that this is development code – it\’s not a good idea to rely on the current Vidalia network if you really need strong anonymity.
By default, Tor is configured to run at startup. If you do not want Vidalia to run on startup, you can disable this by selecting \”Customize\” in the Installer, and then un-checking the \”Tor Startup Script\” box. Be sure to leave the other boxes checked. Once the installer is finished and your computer restarts, Tor will start automatically. Tor comes configured as a client by default. It uses a built-in default configuration file in /Library/Tor/torrc, but most people won\’t need to change any of the settings.
Privoxy is installed as part of the Tor bundle package installer. Privoxy is a filtering web proxy that integrates well with Tor. Once it\’s installed, it will start automatically when your computer is restarted. You do not need to configure Privoxy to use Tor. A custom Privoxy configuration for Tor has been installed as part of the installer package.

Plenty of utilities can recover deleted files, but what if you can’t boot your computer, or the whole drive has been formatted? Here’s how to dig deep and recover the most elusive deleted files, or even whole partitions.
We’ve shown you simple ways to recover accidentally deleted files, even a simple method that can be done from an Ubuntu Live CD, but for hard disks that have been heavily corrupted, those methods aren’t going to cut it. In this article, we’ll examine four tools that can recover data from the most messed up hard drives, regardless of whether they were formatted for a Windows, Linux, or Mac computer, or even if the partition table is wiped out entirely.
Note: These tools cannot recover data that has been overwritten on a hard disk. Whether a deleted file has been overwritten depends on many factors – the quicker you realize that you want to recover a file, the more likely you will be able to do so.
To show these tools, we’ve set up a small 1 GB hard drive, with half of the space partitioned as ext2, a file system used in Linux, and half the space partitioned as FAT32, a file system used in older Windows systems. We stored ten random pictures on each hard drive.
We then wiped the partition table from the hard drive by deleting the partitions in GParted.
Is our data lost forever?
All of the tools we’re going to use are in Ubuntu’s universe repository.
To enable the repository, open Synaptic Package Manager by clicking on System in the top-left, then Administration > Synaptic Package Manager.
Click on Settings > Repositories and add a check in the box labelled “Community-maintained Open Source software (universe)”.
Click Close, and then in the main Synaptic Package Manager window, click the Reload button. Once the package list has reloaded, and the search index rebuilt, search for and mark for installation one or all of the following packages: testdisk, foremost, and scalpel.
Testdisk includes TestDisk, which can recover lost partitions and repair boot sectors, and PhotoRec, which can recover many different types of files from tons of different file systems.
Foremost, originally developed by the US Air Force Office of Special Investigations, recovers files based on their headers and other internal structures. Foremost operates on hard drives or drive image files generated by various tools.
Finally, scalpel performs the same functions as foremost, but is focused on enhanced performance and lower memory usage. Scalpel may run better if you have an older machine with less RAM.
If you can’t mount your hard drive, then its partition table might be corrupted. Before you start trying to recover your important files, it may be possible to recover one or more partitions on your drive, recovering all of your files with one step.
Testdisk is the tool for the job. Start it by opening a terminal (Applications > Accessories > Terminal) and typing in:
sudo testdisk
If you’d like, you can create a log file, though it won’t affect how much data you recover. Once you make your choice, you’re greeted with a list of the storage media on your machine. You should be able to identify the hard drive you want to recover partitions from by its size and label.
TestDisk asks you to select the type of partition table to search for. In most cases (ext2/3, NTFS, FAT32, etc.) you should select Intel and press Enter.
Highlight Analyse and press Enter.
In our case, our small hard drive has previously been formatted as NTFS. Amazingly, TestDisk finds this partition, though it is unable to recover it.
It also finds the two partitions we just deleted. We are able to change their attributes, or add more partitions, but we’ll just recover them by pressing Enter.
If TestDisk hasn’t found all of your partitions, you can try doing a deeper search by selecting that option with the left and right arrow keys. We only had these two partitions, so we’ll recover them by selecting Write and pressing Enter.
Testdisk informs us that we will have to reboot.
Note: If your Ubuntu Live CD is not persistent, then when you reboot you will have to reinstall any tools that you installed earlier.
After restarting, both of our partitions are back to their original states, pictures and all.
For the following examples, we deleted the 10 pictures from both partitions and then reformatted them.
PhotoRec
Of the three tools we’ll show, PhotoRec is the most user-friendly, despite being a console-based utility. To start recovering files, open a terminal (Applications > Accessories > Terminal) and type in:
sudo photorec
To begin, you are asked to select a storage device to search. You should be able to identify the right device by its size and label. Select the right device, and then hit Enter.
PhotoRec asks you to select the type of partition to search. In most cases (ext2/3, NTFS, FAT, etc.) you should select Intel and press Enter.
You are given a list of the partitions on your selected hard drive. If you want to recover all of the files on a partition, then select Search and hit Enter.
However, this process can be very slow, and in our case we only want to search for picture files, so instead we use the right arrow key to select File Opt and press Enter.
PhotoRec can recover many different types of files, and deselecting each one would take a long time. Instead, we press “s” to clear all of the selections, and then find the appropriate file types – jpg, gif, and png – and select them by pressing the right arrow key.
Once we’ve selected these three, we press “b” to save these selections.
Press Enter to return to the list of hard drive partitions. We want to search both of our partitions, so we highlight “No partition” and “Search” and then press Enter.
PhotoRec prompts for a location to store the recovered files. If you have a different healthy hard drive, then we recommend storing the recovered files there. Since we’re not recovering very much, we’ll store it on the Ubuntu Live CD’s desktop.
Note: Do not recover files to the hard drive you’re recovering from.
PhotoRec is able to recover the 20 pictures from the partitions on our hard drive!
A quick look in the recup_dir.1 directory that it creates confirms that PhotoRec has recovered all of our pictures, save for the file names.
Foremost
Foremost is a command-line program with no interactive interface like PhotoRec, but offers a number of command-line options to get as much data out of your had drive as possible.
For a full list of options that can be tweaked via the command line, open up a terminal (Applications > Accessories > Terminal) and type in:
foremost –h
In our case, the command line options that we are going to use are:
Our foremost invocation is:
sudo foremost –t jpeg,png,gif –o foremost –v –i /dev/sda
Your invocation will differ depending on what you’re searching for and where you’re searching for it.
Foremost is able to recover 17 of the 20 files stored on the hard drive.
Looking at the files, we can confirm that these files were recovered relatively well, though we can see some errors in the thumbnail for 00622449.jpg.
Part of this may be due to the ext2 filesystem. Foremost recommends using the –d command-line option for Linux file systems like ext2.
We’ll run foremost again, adding the –d command-line option to our foremost invocation:
sudo foremost –t jpeg,png,gif –d –o foremost –v –i /dev/sda
This time, foremost is able to recover all 20 images!
A final look at the pictures reveals that the pictures were recovered with no problems.
Scalpel
Scalpel is another powerful program that, like Foremost, is heavily configurable. Unlike Foremost, Scalpel requires you to edit a configuration file before attempting any data recovery.
Any text editor will do, but we’ll use gedit to change the configuration file. In a terminal window (Applications > Accessories > Terminal), type in:
sudo gedit /etc/scalpel/scalpel.conf
scalpel.conf contains information about a number of different file types. Scroll through this file and uncomment lines that start with a file type that you want to recover (i.e. remove the “#” character at the start of those lines).
Save the file and close it. Return to the terminal window.
Scalpel also has a ton of command-line options that can help you search quickly and effectively; however, we’ll just define the input device (/dev/sda) and the output folder (a folder called “scalpel” that we created on the desktop).
Our invocation is:
sudo scalpel /dev/sda –o scalpel
Scalpel is able to recover 18 of our 20 files.
A quick look at the files scalpel recovered reveals that most of our files were recovered successfully, though there were some problems (e.g. 00000012.jpg).
In our quick toy example, TestDisk was able to recover two deleted partitions, and PhotoRec and Foremost were able to recover all 20 deleted images. Scalpel recovered most of the files, but it’s very likely that playing with the command-line options for scalpel would have enabled us to recover all 20 images.
These tools are lifesavers when something goes wrong with your hard drive. If your data is on the hard drive somewhere, then one of these tools will track it down!

There’s nothing worse than buying new gear that malfunctions shortly after you purchase it. If you’re in the market for a new laptop, check out warranty-provider SquareTrade’s detailed laptop-reliability report to find the most dependable hardware.
The warranty company released a research paper late last year analyzing failure rates for over 30,000 laptops covered by their warranties. The report is full of good information worth considering before your next big purchase. The highlights of the study:
- Looking at the first 3 years of ownership, 31% of laptop owners reported a failure to SquareTrade. Two-thirds of this failure (20.4%) came from hardware malfunctions, and one-third (10.6%) was reported as accidental damage.
- Netbooks are projected to have a 20% higher failure rate from hardware malfunctions than more expensive laptop computers.
- ASUS and Toshiba were the most reliable manufacturers, with fewer than 16% having a hardware malfunction over 3 years.
It’s interesting to note that, on a whole, netbooks are a lot more failure prone than laptops. It’s also perhaps a little surprising that a company like Apple, known for its hardware, still ends up a percentage point or two worse off than companies like ASUS and Toshiba when it comes to laptop malfunction rates.
Got a laptop brand you trust above all others for its reliability? Sing its praises in the comments. Thanks leonardtj!

Got a spreadsheet full of contacts and addresses you’d like to map out without spending hours manually copying and pasting between your spreadsheet and a mapping application? Reader A3sthetix points us toward BatchGeo, a smart spreadsheet-to-Google-Map conversion tool.
I was faced with the daunting task of mapping over a hundred addresses to a map today. In researching solutions, I came across a Google Maps mashup called BatchGeo, which made the whole task unbelievably simple. All you need to do is paste a table or spreadsheet into the webapp and it does the rest, including validating columns and addresses. The auto-generated map can then be saved for later use.
BatchGeo could also be used for apartment hunters that want to visualize a spreadsheet of potential dwellings. I’m currently using it for creating a store locater and looking at package shipments to correlate common destinations (the long-term goal is to determine where a distribution center might be useful.)
As you can see in the video, the end product even retains information from other columns in your original spreadsheet (like name and telephone number, for example), which is particularly handy.

By now, you’ve probably heard that Facebook has made some big changes that affect your privacy. However, you might not know what they are. So far, the changes have been explained in the language of the people that they benefit: companies and app developers. What about us, the end users? Here’s a handy collection of the best tips that we could find for protecting your privacy on Facebook’s wild new frontier.Obviously, the best way to keep your information private on Facebook is to not have a Facebook page. You can deactivate your account using the link at the bottom of the account settings page, which hides your info and gives you the option to reactivate later and pick up where you left off. If you’re looking for a full, permanent, once-and-for-all Delete Account link, you can find it in Facebook’s help center.
If you’re not going to delete your account, you should (at a minimum) pop open your Application Settings and delete any Facebook apps that you aren’t using. Under new Facebook rules, apps can hold onto your info as long as they like (as opposed to the old limit of 24 hours). That makes using apps more convenient (you don’t have to authorize them repeatedly), but it also means that you’re trusting them a lot more. If you don’t trust or don’t use an app, just hit that X and disconnect it from your account.
Another new Facebook feature that you have to be careful of is that all of your interests and favorites (and even your hometown) will be linked to Facebook pages now. These will be visible to search engines and anyone who finds your page. To get around this, you can delete that info altogether, or move it to the freeform “About Me” box.
There’s also a sneaky new preference called Instant Personalization that you’ve been automatically opted into (gee, thanks Facebook!) This is that “Facebook automatically shares ALL of your data with its special partner sites” feature I wrote about last month, and now it’s here. So far, the partners are Yelp, Microsoft’s Docs.com, and Pandora. Go ahead and find Instant Personalization in preferences under Applications and Web sites and uncheck it.
Facebook warns you that even unchecking Instant Personalization won’t stop your friends from automatically sharing your info to personalize their experiences on the partner sites. Friends who don’t care about privacy are a major leak on Facebook, so you’ll also want to uncheck every single box under the “What your friends can share about you” section of the preferences. It’s under Applications and Web sites.
Of course, it doesn’t help to keep your friends from sharing your info if you’re sharing it yourself. To make sure you’re not, go to Profile Information, and make sure everything is set to Only Friends. It’s a tedious process, but it’s highly recommended.
Remember, the only way to guarantee that Facebook won’t share, sell, or expose your information is to not put that information on Facebook at all. Of course, Facebook is harder and harder to avoid as it becomes a more useful, more essential part of the Web. It’s important to take basics steps in order to make sure you’re only sharing what you want to.
