Stop it: “email AT domain DOT com” is making a spammer’s job easier

Its pretty well established that “email AT domain DOT com” offers only marginal protection from spammers getting your email address, but sometimes, it makes it even easier.  Look at this google query for “at gmail dot com” restricted to

From a search like this I can harvest thousands of reliable emails off, or the general internet, using only the search engine context.  In fact, I did, here’s 500 gmail addresses from LinkedIn with the last few letters removed.

Search engines don’t index special characters, so an email of the form “” is protected from this sort of discovery.  The basic trouble is “email AT domain DOT com” is completely indexed by search engines, and its unique enough that whenever you see “at domain dot com”, you know its part of an email address.

If you really want to evade an email harvester, put up an image of your address, use some css/js obfuscation techniques, or encode your email in a simple statement like ‘my last name at’

Personally, I already get enough spam, and gmail provides excellent enough spam filters, that I don’t mind spreading my real email address around anyway.  Go ahead, send me a note at if you wish!


Some iDoor source code…

I’ve  gotten enough requests for the code I figured I should just release it into the wild.  Use this only as an example of how to do some fancy things with phidgets, don’t use it as an example of how to actually write good code!  You can checkout the nasty threads and the door protocol that requires every message starts with ‘awesomesauce’!   Enjoy.


iDoor – iPhone Controlled Hydraulic Door

Opening up the door to your dorm room?

There’s an app for that.

Here’s the story of iDoor, the iPhone controlled hydraulic dorm room door.  Enjoy. Credits to Greg Schroll for most of the hardware.

Life at MIT can be tough. With all the problem sets, and projects taking up time, when I come back to my dorm room to crash, I don’t want to waste time opening doors myself! That’s why my room is outfitted with an iPhone controlled hydraulic door opener and unlocker.  Just tap the “iDoor” app on my phone’s home screen, and the door opens for me.  Its 2009 after all, about time we stopped carrying around shaped bits of metal to open up locked doors.

All the apps I need

Chris Varenhort’s iPhone has one special app…

When security isn’t my chief concern, I can even ditch the phone altogether and just give iDoor a ‘secret’ knock (not so secret any more) and let the vibration sensor trigger the door opening.  See the video above for the full run through.

Automatic door opener switch!

Found this laying around somewhere…sorry for the isight camera picture…

apparently its wireless, and pretty darn simple at that. Such a small board, and a 9v battery. I think I’ll turn the button into a button to operate my own door, and then use the board to make myself my own wireless automatic door opener.

Facebook phone numbers onto my phone!

So, I got a new phone recently.  Not wanting to awkwardly type numbers in, or worse yet, ask people, I wrote a little script to convert what I copied from the facebook mobile phonebook to a nice CSV file.  I then used BitPim and bluetooth magic to transfer the numbers directly to my phone!  Viola, hundreds of phone numbers on my phone in a few minutes.  The perl script to make the conversion is below…


#for file slurping
undef $/;
$line = <INPUT>;

#get ride of empty lines
$line =~ s/\n\n/\n/g;

#make the numbers pretty
$line =~ s/([0-9]){0,1}[\-\.\)\( ]([0-9])/$1$2/g;
$line =~ s/([0-9]){0,1}[\-\.\)\( ]([0-9])/$1$2/g;

#we only want mobile numbers (ending in M)
$line =~ s/([0-9])M\n/$1\n/g;
$line =~ s/\n([0-9])+[A-Za-z]\n/\n/g;

#get ride of the letter headings
$line =~ s/\n[A-Z]\n/\n/g;
$line =~ s/\n[A-Z]\n/\n/g;
$line =~ s/\n[A-Z]\n/\n/g;

#Comma delimitation!

$line =~ s/\n(.+[a-zA-Z])\n([0-9]{1,})/\n$1,$2/g;
$line =~ s/\n(.+[a-zA-Z].+)\n([0-9]{1,})/\n$1,$2/g;

print “$line”;
