IxQuick search engine

I’m concerned about Google having a monopoly on search, and tracking their users for search terms, and much more.

So use another search engine.

I’ve been using IxQuick on-and-off for years, and almost exclusively for the last six months: https://ixquick.com/

First, I set the default Search Bar plugin to IxQuick from one of the many selections at the Mycroft project .

Then I also set Firefox’s address bar to do keyword searches on IxQuick:

1. type about:config in the address bar
2. Acknowledge the potential for damaging your system
3. Search for the keyword.URL entry
4. Change it to https://ixquick.com/do/metasearch.pl?query=

Now any keywords you type into the address bar will be looked up by IxQuick.

IxQuick is a metasearch engine, which searches All the Web, Digg, Qkport, Ask/Teoma, EntireWeb, Wikipedia, Bing, Gigablast, Yahoo, Cuil and Open Directory. Almost everything except Google. IxQuick claims that it does NOT collect or share your personal information, and keeps logs no longer than 48 hours.

All in all, I’ve been very pleased with the results IxQuick provides.

DuckDuckGo search engine

To put DuckDuckGo in the Search Bar, browse to the DuckDuckGo site, pull down the list of search engines, then click on “Add DuckDuckGo”.

To set up DuckDuckGo as the default search engine for the address bar:

1. type about:config in the address bar
2. Acknowledge the potential for damaging your system
3. Search for the keyword.URL entry
4. Change it to https://duckduckgo.com/?q=

I haven’t used DuckDuckGo much at all, but I’ve only heard favourable reports…

Note that there are many other references to Google in the about:config settings, so if you make only these changes you’re still not Google Free.

No Google

Hi IT Peeps,

I was wondering if I would cause major havoc if I downloaded google chrome? Will it mess anything up? Any recommendations?

My answer:

What problem are you trying to solve? What’s the question that gets answered “Install Google Chrome”?

Google the company is becoming ever more pervasive in our Internet lives. Google’s business is not providing a search engine for free; Google’s business is to sell our demographic information to advertisers. They gather that demographic data by luring us in with relevant search results, free e-mail and slick looking browsers.

Google collects personal information, including information that was voluntarily given to Google (for instance, by signing up for GMail or Google Plus; posting a video on YouTube), information that was collected anonymously (eg. when you perform a Google search or watch a YouTube video and Google records the search terms, your IP address, and leaves a cookie on your computer), and information that Google collected as it does its web indexing (comments you’ve left on a newspaper site, Tweets you’ve made, messages you’ve posted to public mailing lists). Google then correlates all this data based on IP address, cookies, e-mail addresses, your name, geo-location (finding out where you are based on your WiFi connection or IP address).

As of 1 March 2012 Google changed its privacy policies to combine data mining from all its holdings – the search engine, YouTube, Picasa, Google Maps, Google Plus, Google Mail, &c. I didn’t think too much of that, since I had thought that Google had always aggregated its data. According to an article I read^[1] that’s actually a new development. Google used to keep all its data mining separate, in fact, kept it so separate that it didn’t even correlate its adwords between different messages in GMail. With the new privacy policy that’s all changed, and everything is now aggregated, correlated, and retained to be sold to the highest bidder. Google says we’ll never sell your personal information or share it without your permission, but you grant that permission every time you agree to the Terms of Service and Privacy Policies when you sign up for Google’s services.

Remember the Google Toolbar? Every search request, every URL, and every local file you opened in a browser with the Google toolbar installed was sent to the Google servers. There was a report of someone who opened confidential company documents with IE and the Google toolbar, only to find those reports cached on Google’s servers. Google Chrome is far more invasive than a mere toolbar.

Google Chrome does not have the same set of security-related add-ons that Firefox offers. For your best privacy protection and security, use Firefox with the NoScript, AdBlock Plus, HTTPS-Everywhere and Force-TLS extensions. See my article on Browser Security for details on installing and configuring them.

–Bob, who will be getting fitted for a new tinfoil hat at lunch…

Copy Bunny Conga Line

One area, however, where I think the media companies may have more reason for optimism with streaming than Doctorow believes is with video. Music and video may diverge more strongly in regards to streaming than in other aspects of digital distribution. While storage is getting cheaper every day, high definition video remains relatively sizeable, and generally there is not as much repetition as with music, decreasing the inherent inefficiency of streaming.

You say that now. When Napster first hit the Net it was said that while music was readily available, movies were safe from copying because of their relatively large size.

And in the 1990s when the photographers were all up in arms about pictures getting copied, it was said that other arts (like music and film) were safe from copying because of their relatively large size.

And in the days of the BBS when people were swapping highly compressed GIFs it was said that full colour pictures were safe from copying because of their relatively large size.

And when home taping was killing music, it was thought that movies were safe from copying, not because of their relatively large size, but because the technology to copy movies cost tens of thousands of dollars and was available only to studios.

The only reason that hi-def movies aren’t being downloaded or streamed^[1] is because North American service providers offer such miserable bandwidth to the consumer. Hi-def will succumb to swapping, sharing and copying as soon as the ISPs realize they can make a buck by providing the bandwidth to do so.

Next, it’ll be complete libraries of music that get compiled and copied. Then the complete catalogs of the studios. “Have you copied Warner Brother’s holdings yet?” “Got ‘em, but I’ll swap you Sony for Disney”.

Soon, everyone will have everything. That’ll put an end to file copying.

Browser selection

This article deals only with securing Mozilla Firefox. Firefox offers an wide selection of extensions that can help secure the browser. Google Chrome, Opera and Safari also offer some extensions, but I have not tested them. Microsoft Internet Explorer appears to support Add-ons, but Version 8 offers none for browsing security.

Internet Explorer is particularly vulnerable. In part, this is because IE is by far the most popular browser, and so it suffers the most attacks. Because it is the most popular browser it is especially targeted for attack by malusers. And compounding the problem, Microsoft has been slow to acknowledge vulnerabilities in its products, never mind fixing them.

Privacy settings

Privacy is not so much about keeping your personal information secret, but about keeping control over your personal information. If I choose to tell Facebook my name, age and browsing habits that’s OK, but my privacy is violated if Facebook finds out about my browsing habits if I don’t tell Facebook myself.

Malware is pretty good at correlating information when you least expect it. For example, you may keep your browsing history confidential, but allow Javascript to change the layout of your screen. To do so Javascript reads elements of the Document Object Model (DOM), including the colour of text. But if a link is coloured purple instead of blue, then Javascript can figure out that you’ve visited that link before, violating your privacy settings for browsing history.

To see your Firefox Privacy settings select Tools, Options and click the Privacy icon.

Settings for Firefox Privacy options

For maximum protection check Tell Web sites I do not want to be tracked and select Firefox will: Never remember history. But having to type in all your passwords and data every time you access the same web sites can be inconvenient, so I actually browse with the setting Firefox will: Use custom settings for history, leaving Always use private browsing mode unchecked. It is usually safe to have Accept cookies from sites turned on, with Accept third-party cookies turned off and Keep until: I close Firefox selected. Custom settings for Clear history when Firefox closes has only Cookies and Active Logins checked:

Firefox Clearing History

Security settings

To see Firefox Security settings select Tools, Options, then click on the Security icon.

Screenshot - Firefox, Tools, Options, Security

For maximum security, make sure all the checkboxes are checked.

Warn me when sites try to install add-ons will avoid drive-by infections, which is when merely browsing a Web page with Javascript enabled can launch malicious processes. This will at least give you a warning.

Block reported attack sites and Block reported web forgeries do add some additional protection from malware sites, but potentially at some expense of your privacy. Every 30 minutes Firefox downloads a list of malware sites. If you browse to such a site then Firefox will check for that particular site immediately before blocking it. It uses Google’s malware list to do so, and will send Google’s cookies when checking.

You can test for phishing protection at the phishing test site and for malware protection at the malware test site.

Use a master password will encrypt the list of passwords stored on your computer. This is mostly useful if your computer should get stolen or left on the bus, but without the Master Password it might be possible for a malware site to retrieve your list of passwords through some (as yet unknown) vulnerability.

Security Extensions

Firefox’s extensive collection of extensions (Add-ons) make it my preferred browser.

NoScript

NoScript prevents Javascript from executing on specific web sites.

Javascript determines the fourth characteristic of a web page (Content, Semantics, Presentation, Behaviour). A well-designed web site will degrade gracefully — if the browser cannot manage the page layout (Presentation), it should still be able to identify the components of a page such as paragraphs and headers (Semantics), and still show the Content. Even if the browser can’t identify a paragraph from a heading (Semantics), it should always show the content. Javascript is responsible for the behaviour of a page. This is what makes Google Maps’ slippy map work when you drag the mouse cursor across the page. That behaviour degrades gracefully, so that when you view Google Maps with Javascript disabled you can still see a static map. Sadly, many web sites today are designed so that Javascript is required to show the content. NoScript addresses this problem by selectively allowing you to enable Javascript for those sites that you trust.

NoScript has expanded its scope so that it now also checks for Cross-Site Scripting vulnerabilities, Application Boundary violations, and other esoteric security concerns.

Adblock Plus

Adblock Plus removes ads. That’s wonderful all by itself, but there’s more! When ads are blocked, you don’t waste any bandwidth downloading them. But there’s more! The hits from Web Bugs aren’t recorded and tracked. And blocked ads from third-party sites can no longer query third-party cookies, or enable cross-site scripting attacks.

When you install Adblock Plus you’ll be asked to subscribe to one of the pre-defined block lists. I usually choose EasyList or Adblock.org.

Force-TLS

Force-TLS requests an encrypted page (https) when the server supports it. The functionality is now built into Firefox directly, but Force-TLS still provides a handy dialogue box to add Web sites for servers that don’t automatically switch to https.

HTTPS Everywhere

HTTPS Everywhere forces a Web pages to use https, and can change the URL for those sites that use different URL paths for their secure content. HTTPS Everywhere only works for Web sites in its Preferences list:

HTTPS-Everywhere preferences

HTTPS Everywhere is not maintained on the Mozilla Add-ons web site, so you have to download it from the EFF directly. Firefox will ask you to verify that you want to install an add-on from an unknown site. Click on the Allow button to install the HTTPS Everywhere add-on.

Installing the HTTPS-Everywhere extension in Firefox

Keeping Updated

Security is not a single solution to a single problem. It is a constantly evolving process that tries to keep up with constantly evolving attacks. It is important to keep everything up-to-date.

Updating the Browser

To ensure that the browser and all its extensions stay up-to-date check all the boxes on the Tools, Options, Advanced, Update screen:

Updating Firefox

Updating Extensions

To update the Firefox extensions select Tools, Add-ons, click on the Tools for all add-ons button, and make sure there is a check mark beside Update Add-ons Automatically. If there is no check mark then click on Update Add-ons Automatically, and you should also perform updates manually by selecting Check for Updates. If there are any updates a View all updates link will be displayed, click on it, then click on the Update now button for each add-on in the list.

Screenshot showing the 'Update' menu

Updating the Operating System

Finally, no amount of browser security will keep you safe if your operating system is not safe. Be sure to activate Windows Updates (or Linux Updates, or AppleMac Updates), and keep your Anti-virus software, firewall, spam filters and other security software up-to-date.

–Bob.

Delete

The rest of us, Prone to Pecadillos, may occasionally write blogposts and then change our minds about the content. When that happens it’s best not to make changes or delete posts without letting your readers know.

Instead of making a wholesale change to a post it’s better to create a new post. Imagine if someone wrote about a similar issue, quoted from your post and provided links to it. Now your post has changed, and the links no longer make sense because the content has changed. Or someone makes a comment on a post, the content of the post is changed, and now the comment has nothing to do with the post.

Instead, create a new post with a new link. It’s a good idea to keep the original post; you could delete it, but then other people’s links would return an error (that’s called “link rot”).

About the only good reason for modifying an existing post is to correct an error. Even then you shouldn’t delete the incorrect material, but indicate it should be deleted by using the <del> tag, and marking the new material with an <ins> tag. For example:

The Javan Rhinoceros <del>has only one survivor </del> <ins> is now extinct</ins> in Vietnam.

This would show with crossed-out text for <del> and highlighted text for <ins>, like this:

The Javan Rhinoceros has only one survivor is now extinct in Vietnam.

(which is a sad development, and may be worthy of a post of its own).

If you really want to delete a post then replace it with text like “This post has been removed by the author”. If you do that then you should delete or hide the comments too.

These are open and transparent ways to indicate deletions. It’s merely an online publishing convention, since there really isn’t a style guide for HTML like Strunk and White’s in the online world. Or, more accurately, there are far too many Strunk and White’s in the online world!

Key by Quasimondo

Some ID would also be a good idea, for those who do not already know you.

No no no.

If people don’t know you, then they shouldn’t be signing your key. If you don’t know someone, then you shouldn’t be signing their key.

Using ID of any sort is assigning trust by proxy to an “authority”. You’re no longer vouching for a person based on your own knowledge, but relying on the “authority” to provide that trust. If you’re going to rely on third-party authorities you might as well revert to a hierarchical PKI and pay lots of money to a certificate authority to assign levels of trust for you.

The point of the keysigning is to associate a key value with a real person, with no opportunity for a Man in the Middle attack ^[1]. It is not to verify name, address and permission to drive in Ontario.

When I sign your key it is not because the government says that you’re allowed to drive under your name, but I sign your key because I believe that you’re the same guy who drinks Jagermeister and hacks on Blackberries and hangs out at the Syrup Festival. It is based on my personal knowledge of you, and my trust in your claim that you own the GPG key with fingerprint D2CCE5EA ^[2].

The Web of Trust extends this, so that since I trust your identity and judgment, I’m also likely to grant some level of trust to the people you trust. After a successful keysigning party then I’m going to trust many more people because they’re all trusted by people I trust. And I’ll be trusted by more people, because they trust the people who have signed my key.

So, how do you hold a keysigning party? Here’s an excerpt from the PGP FAQ:

Q: What’s a key signing party?

A: A key signing party is a get-together with various other users of PGP for the purpose of meeting and signing keys. This helps to extend the web of trust to a great degree, making it easier for you to find one or more trusted paths to someone whose public key you didn’t have.

Kevin Herron has an example of a keysigning party announcement page ^[3].

Q: How do I organize a key signing party?

A: Though the idea is simple, actually doing it is a bit complex, because you don’t want to compromise other people’s private keys or spread viruses (which is a risk whenever floppies are swapped willy-nilly). Usually, these parties involve meeting everyone at the party, verifying their identity and getting key fingerprints from them, and signing their key at home.

Derek Atkins has recommended this method:

There are many ways to hold a key-signing session. Many viable suggestions have been given. And, just to add more signal to this newsgroup, I will suggest another one which seems to work very well and also solves the N-squared problem of distributing and signing keys. Here is the process:

1. You announce the keysigning session, and ask everyone who plans to come to send you (or some single person who will be there) their public key. The RSVP also allows for a count of the number of people for step 3.

2. You compile the public keys into a single keyring, run pgp -kvc on that keyring, and save the output to a file.

3. Print out N copies of the pgp -kvc file onto hardcopy, and bring this and the keyring on media to the meeting.

4. At the meeting, distribute the printouts, and provide a site to retrieve the keyring (an ftp site works, or you can make floppy copies, or whatever — it doesn’t matter).

5. When you are all in the room, each person stands up, and people vouch for this person (e.g., “Yes, this really is Derek Atkins — I went to school with him for 6 years, and lived with him for 2″).

6. Each person securely obtains their own fingerprint, and after being vouched for, they then read out their fingerprint out loud so everyone can verify it on the printout they have.

7. After everyone finishes this protocol, they can go home, obtain the keyring, run pgp -kvc on it themselves, and re-verify the bits, and sign the keys at their own leisure.

8. To save load on the keyservers, you can optionally send all signatures to the original person, who can collate them again into a single keyring and propagate that single keyring to the keyservers and to each individual.

I’m going to have to put my key signature where my mouth is. Hopefully there will be another key signing party soon, for which I will be more prepared.

–Bob.

^[1] Yes, it is still possible to have a meatspace MitM attack if you’re signing keys for people you don’t know and relying on ID. If you’ve never met me before then it is possible that someone mugs me in the parking lot, takes my ID and wears my goofy hat. If you don’t know me you would never be able to tell the difference, and you’d be signing a key for the wrong person.

^[2] Although that’s really my PGP key, so as not to divulge the identity of innocent and unsuspecting Key Signing Party Organizers.

^[3] Sadly, Kevin Herron makes the same mistake of requiring "Positive picture ID". Please ignore that part.

Don't Panic, They're Only Vogons by Patrick Hoesly

After dissing Google Plus I was persuaded to try it out for a while before rendering a verdict. So now it’s been over two months, and my verdict is: Mostly Harmless.

When I get home after a hard day of working with a computer, I sit down for a pleasant evening of relaxation with a computer. I read my e-mail, read the news, and read the microblogs. I subscribe to 55 people on Identi.ca, and I follow 84 people on Twitter. Those 139 people generate sufficient 140 character messages to keep me reading until bedtime and beyond.

But on my Google Plus account, I have 27 people in my circles. Those 27 people create a lot of large messages. In fact, they generate a lot more content than my 139 Identicats and Tweeple, since Google Plus puts no limit on the size of messages.

22 of the 27 people are in my Tech Circle. But instead of receiving only technical content from these people, they’re posting messages about vacations, favourite bands, philosophy, and yes, pictures of cats.  Now, this happens on the microblogs too, but on a microblog it’s limited to 140 characters, and I can ignore them.  On Google Plus the posts are much longer, have pictures attached, comments from other people, and those ubiquitous “John Q. Public originally shared this post” and “Click to +1 this post”.  Google Plus does not have the tools to filter messages by content, or even a method to collapse a conversation thread.

There’s no Atom/RSS feed, so I can’t use my preferred feed reader to analyze, sort and organize my Google Plus message stream. And I don’t know of any third-party applications to read, write and manage content on Google Plus. Google Plus does allow the export of all its content, under Account Settings, Data Liberation. Contact info is in the standard vCard format, suitable for importing into addressbooks.

Kudos to Google for giving users useful control of their data. Still, Google also has access to that data, and continues to collect ever more. In the past I’ve recommended Google Mail as a preferred no-cost e-mail host. Recently Google has taken to verifying new users by requiring them to supply a phone number. Google then sends a text message for the user to enter into the registration form. This is a level of data collection that I find creepy, and so I no longer recommend Google Mail.

Finally, to top it all off are the Google Nymwars. Much has been written about why Google’s policy of requiring real names is wrong-headed. Some people whom I might follow have stopped using Google Plus because of the nymwar controversy. I think I’ll be joining them in disdaining Google Plus.

• Google Minus: Banality of user content (not Google’s fault)
• Google Minus: Lack of management tools
• Google Plus: User control over data
• Google Minus: Google control over data
• Google Minus: Nymwars

I think that Google Plus is not the Facebook Killer the folks in Mountain View want it to be.

I won’t be using it. Google has too much of my data already.

For gushing, sycophantic reviews see Mashable and Techcrunch.

Update 8 July 2011: Someone pointed out that I should probably investigate Google Plus before dissing it, so I’m licking the Google salt block. There will another blog post with the results of this investigation… In the meantime, Circle Me!

Update: 13 October 2011: The Verdict on Google Plus: Mostly Harmless

I’m specifically looking for a free/libre operating system that will run a Graphical User Interface on a 10-year-old laptop, 700 MHz Intel CPU, 256 MiBytes RAM (but 128 MiBytes would be better), an 8 GiByte hard drive and an 800×600 screen.

If you know of any other lightweight distributions please leave a comment. Also please leave a comment if you can help fill out the chart – the distributions’ documentation is pretty inadequate when it comes to listing minimium system requirements.

I expect this post to be a continuous work-in-progress.
