Moblogging–Wardriver style

“According to the Oxford-English dictionary, the word ‘snapshot’ was
first used
in 1808 by an English sportsman by the name of Sir Andrew Hocker.
He noted in his diary
that every bird he shot that day was taken by snapshot.
meaning a hurried shot,
without deliberate aim. Snapshot then… was originally
a hunting term.”
-One Hour Photo

Over a month ago I
announced
that the articles formerly known as “Road Warrior Wednesday”
would take a new name to depict the “edge” that it was intended to
ooze. Since that time I have brought you such terrifying and controversial topics
as USB gadgets, messenger bags and presentation remotes. I know, I haven’t been
keeping up my end of the bargain. Well, this time around, I”m hoping to ruffle
a few more feathers…we’re going MobloggingóWardriver style.

Moblogging?
Moblogging is short for “mobile blogging” which, in tern, is short
for “mobile web logging” It is a activity practiced by a growning
number of people who form a community of web sites that document the events
and experiences of the various lives through the use of digital cameras both
standalone and those that come with some of the latest mobile phones. Mobloggers
take these snapshots and post them on their web sites. They often offer insites
into the meaning the particular image has for them and invite you, the visitor
to leave a comment of your own.

I’ve been moblogging
for a few months now as part of my
personal blog
. And, of course, I invite you to get involved and interact
with me there also. But today I have another activity in mind.

Warchalking?
Warchalking is commonly
conducted in the course of wardriving. (If you don’t know what wardriving is,
why are you here? Okay, it’s when you drive around looking for open wireless
internet connections. Happy now?!) A wifi hotspot is often chalked with a symbol
to denote the type of access, the degree of protection that is in play, the
quality of that signal and sometimes the distance to the actual access point
from the chalk mark. That is warchalking.

Moblogging Wardriver style
Now this is a bit of an experiment and how well it works is entirely up to you
wardrivers. What I propose is that you go out wardriving and when you find a
nice, free, unprotected hotspot that, instead of pulling out your chalk and
marking the sidewalk, take out a camera and email
it to the MacMerc.com
Wardriver Wednesday Moblog.
Here’s how:

Take a picture of the building from which the discovered signal is
emitting.

Attach that image to an email
message addressed to the MacMerc.com
Wardriver Wednesday Moblog
.

In the subject line of that email, enter the name of the signals location.

Use wardriving software like MacStumbler or iStumbler to find out the
name of the access point (the SSID), the channel the access point is using,
the signal strength, whether or not it is protected by WEP and the type
of router. Also take note of your physical location; the street you’re
on and the address of the building that houses the wifi signal. If you
want to get really high tech, use a GPS unit to find your global location
or enter the street address online at Maporama.com.

Now, in the body of the email, type the information you gathered thusly
(replacing the italicized parts with your own information):

SSID = Name of access point
Channel =
Channel number
Signal = Signal strength
WEP = WEP protected? Yes or No?
Router = Router Manufacturer
Location = City, State/Prov, Country
(
GPS location)

Submit that email and watch for your submission
to appear on the MacMerc.com
Wardriver Wednesday Moblog
.

Again, for this idea to work it hinges on the participation of you wardrivers
out there. Get out there and photograph your local hotspots (protected or unprotected,
public or private) and send submit them as I have detailed ablove. The most
recent submission appears below:

The effect is slightly different than the one detailed in the written tutorial and had to be dumbed down for automation’s sake. But, I think you will agree, it still looks pretty slick. Download it and give it a shot. It should work with Adobe Photoshop 7 and above for Mac (or even PC). If you have any trouble post a comment below.

Superior Ad Blocking on OS X

I love surfing the web. I have DSL and I get pretty good download speeds (compared to 56K modems, insane download speeds). Even though I have a good connection, I still hate downloading obtrusive ads. You know those huge “skyscraper” ads, or those pesky Flash ads that seem to take forever to download? Even more annoying are the pop-up ads that show up on a surprising amount of sites considering everyone hates them with a passion (except evil marketing types). I’m about to show you how to block almost all of the aforementioned ads in ANY browser in OS X. If you don’t want to be bothered with pop-ups use a program or browser that disables them. My method only stops the ads from loading, not the window from popping. Chimera has a killer pop-up blocker installed by default (haven’t seen one so far).

Some people may say that it isn’t right to block ads… That’s how sites stay free. That’s true, and that’s exactly why I’m only giving directions to block the big boys that have no concern at all for your privacy (can we say doubleclick?). This will not block ads on MacMerc, MacMinute, MacUpdate or any other well run site. My goal by blocking ads is to speed up surfing. Only graphical ads are blocked… Text ads are let through. If you really like a site and you’re afraid that they will lose income when you block its ads, look around on that site and most likely there are other ways you can support it. Most webmasters would rather all their visitors gave $10 a year than have to run ads. I know MacMerc would icon razz Superior Ad Blocking on OS X . If you can’t find anything just email someone there and ask where you can send a donation. It will be appreciated.

The following is a list of the “Big Boys” in the adserving market that many sites use to outsource ads:

doubleclick.net

linkexchange.com

adsmart.net

admonitor.net

msn.com (not an outsource service but gobs of ads come out of ads.msn.com)

smartclicks.com

focalink.com

bravenet.com

bfast.com

sextracker.com (You’d be surprised)

hitbox.com

valueclick.com

fastclick.net

realmedia.com (these ads are hugely huge)

And there are several more. If you do a lot of “source hunting” you’ll soon notice that 90% of ads come from less than 100 locations.. Should be easy to block right? Well, in OS X it’s a piece of cake.

Open the terminal by going to /Applications/Utilities/ and opening Terminal. You may not have ever used the Terminal before but do not worry, this won’t be hard. Type:

sudo pico /private/etc/hosts

When prompted, enter in your administrator password (if you’re the only user of your computer, it’s just your regular password). When you type nothing will appear on screen (not even *’s). This is a security mechanism. When you finish your password just press enter. You’ll be taken to a screen that should look something like below:

Pico is a simple text editor for Unix. It’s commands are a little funny for Mac users since it uses control instead of command, but it’s otherwise really easy to learn. The ^ key signifies control for any interested souls out there icon razz Superior Ad Blocking on OS X . What this file does is associate hosts. The first line means when a request for localhost comes in send it to 127.0.0.1 (almost the universal address for the local-computer). What we’re going to do is insert some well known ad servers into the right hand column, and send them to 127.0.0.1 in the left hand column. For extra points we’re going to set up a custom 404 error page to keep blocked ads looking pretty. Here is a list I compiled of the most popular/annoying ad servers along with the 127.0.0.1 forwarding address. Copy and paste this list into pico (select the text and press Control-C, in pico use the arrow keys to highlight an area below the last line with text on it and press command-v). Once you successfully copied the addresses press Control-o and hit enter once you see the message asking for a file name. Then hit Control-x. Keep the terminal open for the 404 message step (not a real message that shows in the Terminal, but you need to keep it open for the step that prevents nasty errors to be shown).

Now you need to turn on your personal web server. If you don’t, you’ll have to click through warning messages about every 2 seconds for most every page you visit. To do so just open up the System Preferences by going to the Apple Menu and choosing “System Prefrences…”. Once the preference pane opens, choose Sharing. In the sharing pane, check the persona web sharing box. The pane should look like this before you click the check box:

If you were to restart your computer now, and started browsing the web, you’d notice a lot fewer ads. But, you’d also notice really weird looking error messages. Here’s a picture I took of my browser at Tucows.com:

tucows Superior Ad Blocking on OS X

I think having the ads in place might look better… But the load times without them are much nicer. To fix this, we’re going to make a custom error message. All that text means is that the ads can’t be found on your computer… Of course they can’t… We’re trying to get rid of them! Get back in the Terminal and type:

sudo pico /etc/httpd/httpd.conf

You’ll be greeted with the now familiar Pico interface but now with a lot more text. No worries, this is a down and dirty task. Press Control-w and type (or paste):

ErrorDocument

Look for the following text:

# ErrorDocument 404 /missing.html

Move your cursor with the arrow keys until it’s one character to the right of the #. Hit delete. This “un-comments” the line. We’re telling Apache that when there is a missing page, use missing.html instead of the error message. If you run a web server (like I do) you can get more tricky and throw it to a script that dynamically decides if you’re trying to block an ad or if someone found a broken link on your web server (I’ll save that for part 2). To save this file hit control-o and then control-X. You can close the Terminal. Now just download this file and place it in /Library/Webserver/Documents/.

Go ahead and restart your computer. When you next start your web browser, head over to a large site like CNN or TuCows and notice the difference. I’d suggest using Chimera to get the best effect… no pop windows and no large sive ads. If you go back to TuCows you’ll see a nice ad free version like this:

UPDATE (10/23/08 – 19:02 PT): Thanks to a MacMerc.com reader who submitted this tip to update this tutorial for Mac OS X 10.5:

Just wanted to let you guys know that I recently figured out how to get the Superior Ad Blocking walkthru to work in 10.5. Instead of editting the /private/etc/hosts file (which actually changes the correct one in 10.5) it’s easier to change the /etc/hosts as it will also apply to other users on the computer. Second the httpd.conf has moved from /etc/httpd/httpd.conf to /etc/apache2/httpd.conf. Just trying to help out! Cheers and Good Luck!

Our readers are the best!
