I am befuddled by how @Twitter can miss some blatant cases of spam accounts. So much that I have come close to conclude that these are paid accounts, thus won’t be removed no matter how much they are flagged and/or blocked. Here are some suggestions, based on what I have observed with spammers on Twitter, for spam-matching rules to improve the catch ratio. The accounts I use as examples have been hand-picked, so my points are open to interpretation, and could be way improved with data that Twitter has, such as tweet rate, number of spam flags and blocks, etc. These checks could be triggered in escalating order according to the number of users flagging an account for spam, as an example.

[Update] @Ed has replied to my tweet and part of this post:

I said “I have come close to conclude…”, not that they are paid accounts. But, it defies all logic how an account like @kredits can still be up and running after close to 64.000 (yes, that’s sixty-four thousand) spam tweets that break many of the rules/filters I have written about below. It is not a question of writing an algorithm for every variation, but a set of rules which give individual scores, and a minimum score to suspend an account. Basically, x-spam-score followed by an x-spam-status that determines account suspension, or lack thereof.

Follower to following ratio

Some spam accounts use aggressive follow techniques to try and spread their trash, and this gets reflected by auto-follow bots. The result are accounts with following/followed ratios close to one. Case examples: @Bqe1212 with a ratio of 1.01, or @vidalconsulting with 1.04. Others do not follow this approach, and only follow few accounts, for example, @kredits, with only 168 followers and following 49.

Tweet rate

One case I observed (the account is now suspended, so kudos there) had the particularity that tweets were pushed out every three minutes exactly. Twenty-four hours a day. This is something -very- easy to catch (and equally easy to defeat, but hey, some spammers are dumb).

Tweet content

We can split this check into various sub-checks:

1. Keywords

In the case of @jenlock1014, the word ‘money’ appears in almost every single tweet pushed out. The actual text of the tweets vary, as do the linked URLs, but the keyword is there. Other usual keywords are ‘free’, ‘cash’, and so on.

2. Linking the same URL

In some cases we see links to the same URL in every tweet, such as @Bqe1212, with tweets like:

http://twttr.me/dbxV Q&A: HOW CAN I MAKE MONEY FAST ON THE INTERNET FOR FREE!! NO …: by Chri… http://bit.ly/aJVi6Whttp://twttr.me/dbxV

and

http://twttr.me/dbxV How to Make Money Online With Online Writing Sites: There are many sites … http://bit.ly/cichxl http://twttr.me/dbxV

The target site’s linked short URL is different, but every tweet contains (two in this case!) copies of the same short link. Again, both tweets would also trigger rule #1 above for keywords.

3. Linking the same URL with differing URL shorteners

One technique often used is to spread the target link among various URL shorteners. This is the case of @kredits, which uses snurl.com, ej.uz, short.ie, bit.ly, and others, all of which redirect to the same final URL. A simple check, once an account is flagged for processing, is to follow all shortened URLs and look for patterns. For example:

• Exactly the same URL.
• Same host, same path, but varying query string (oft used to track sources).
• Same host, varying path, but same query string.
• Same host with both varying path and query string.
• Varying subdomains of the same host.

A combination of the above can be used to determine a spam score for a set of given URLs. An extra check when fuzzing techniques are used on the final URL is to parse the target site’s content, looking for similar headers, keywords, image URIs, Google Analytics account IDs, etc.

Reaction tweets™

Many times a spammer searches for certain keywords, and sends a reaction tweet when one is found. As an example, when I sent this reply to Ed Shahzade (@Ed) in reply to his tweet about auto-follower bots and spam, I received this other tweet from @atraiskredits:

@mikepuchol Problēmu var atrisināt ātrais kredīts? Izvērtēs kredīta piedāvājumu! Atver www.opencredit.lv un gaidi naudu savā kontā.

Obviously this is not English, and thus it was sent as a blind reply to my tweet mentioning @kredits without caring much about my original language, or wether I understand the content of the tweet.

On a flagged account, it should be very easy to check when response tweets are sent, by accumulating the words used in the original triggering tweets, and testing the occurrence of each word in all, or a high percentage, of them. As another case example, 10 minutes after @djsandman813 was sent this tweet by @kredits, and he replied this, @atraiskredits sent this reaction tweet. Screenshots below in case they go missing:

* OK “Reaction tweets” is not really trademarked, but maybe it should be!

Account aggregation

Spammers can try to avoid being flagged, or delay detection, by spreading their activity across multiple accounts. The way to detect this is to run a check among flagged accounts for the above filters, eg. catching various accounts all sending reaction tweets with the same short URL.

Account name

Many spammers are not too creative and simply throw random words and letters into the account name – this can also be an indicator of a spammer account.

Reaction flags

When a user receives a spam tweet, his initial reaction may usually be to block flag the sender as spam. An accumulation of such flags, particularly with other indicators such as single tweets towards a user followed by a flag (denoting not a conversation but a directed one-way message), should be enough to suspend an account.

What else?

I’m sure there are many other checks possible, but I have to get back to work – so, @delbius, do I get a job offer? Just kidding – was thinking of the guy who got offered a job at YouTube after writing ‘YouTube Instant’.

It should have been premonitory – while looking for other reviews or info on the upcoming AutoCAD for Mac OS release, I stumbled upon this post by Steve Johnson, owner of cad nauseam, in which he details why AutoCAD for Mac would be a bad idea. While I agreed with some of his views, as this has happened before countless times (case example: Skype, which took years to catch up still lacks behind in features and stability compared to its Windows version), I believed things wouldn’t be that bad.

It turns out there is a list of over 80 holes which Autodesk lists here. Steve has posted this in response, and we now even have an interview with Autodesk staff with money quotes such as:

It really does not make sense for us to implement features on the Mac platform that nobody’s going to use. So basically what the customers are asking for is that we are going to deliver. So like I mentioned before Mac users on the Architecture side shouldn’t notice much of a difference.

OK so you release a trimmed product with not-so-oft used features missing, but at the same price? That doesn’t really fly, no matter how you look at it.

San Rafael, we have a problem

My first reaction when I saw the activation window, right after installing AutoCAD on my Mac Pro, was “OMG they have transplanted the Windows version using Java”. It was SO ugly – in essence, a copy-paste of the Windows workflow into a Mac window, and I suspect they load the content as HTML from a server. Scrollbars? On a modal tool window?

This was before I had to activate the product, which required creating a whole new account, as my teacher login details would not work at all. Autodesk apparently “had no record” of my email address and password, so I had to go through the account creation once more, then finish the activation process, which takes a few more, totally unnecessary, steps. A simple “give us your product code and serial” followed by a “thank you for activating” is more than enough.

Once you fire up AutoCAD, you’re greeted by this splash screen:

which is not particularly informative, but still, shows something. The next thing you are greeted with, at least with the educational version, is this:

OK, so I am using an educational product, but you don’t need to keep reminding me of this fact every time I open a drawing done with a different version – a “don’t remind me again” checkbox is all it takes. The warning would be useful if it came up with drawings you made with a full AutoCAD version, given by others, etc. but it also shows up when creating a new drawing from one of the included templates!

Finally, expecting a normal drawing area, I was greeted by this (click for full size):

It almost reminded me of a BSOD. No matter what I did, I could not even get the cursor to appear in the drawing area, never mind actually draw something. The application was completely unusable. Creating a new drawing, from a template, blank – nothing worked, I either got the blue bars of death (BBOD) or a black drawing area into which everything was sucked into, a-la-black hole. No cursor, cross-hairs, nothing.

The next logical step was to open a drawing recently created using AutoCAD on Windows, and this came up:

I give up. I will try to install it on my MacBook Pro, and see what happens. If the problems reappear, I’ll go back to BootCamp or VMWare with the Windows version, which is fully-featured, stable, and usable. Nice and commendable work on bringing back AutoCAD to the Mac, but so far, it appears the bugs and missing features, even when they are fairly unused ones, are killing the product. Again.

Here is a short list of the resources I used to write this procedure:

Getting Imagemagick (and more) to work with MAMP on OS X – misses info on compiling for Snow Leopard.

Installing Image Magick and Imagick for PHP for MAMP – misses change needed in ports conf file to enable Universal mode.

MAMP & Imagick on Snow Leopard – goes through the pitfalls, which makes the tutorial confusing, but goes into the Universal mode switch.

There are others which I may miss, such as forum posts or other blogs, if so, my apologies. In all, none of them go into the use of older libraries by MAMP in its sandboxed model, which breaks imagick.so when trying to compile it from source rather than using pecl.

1. Install MacPorts

I won’t go into details as you most likely have already done it if you’re reading this. Don’t update your ports yet!

2. Make MacPorts build Universal binaries

Simply edit /opt/local/etc/macports/variants.conf and add +universal at the end of the file. Now, update your ports collection by running:

sudo port -v selfupdate

3. Install Image Magick using MacPorts

Simple:

sudo port install ImageMagick

This takes a while, so go grab a coffee.

4. Update your path

Add

export PATH="$PATH:/opt/local/bin"

to ~/.profile

5. Download and install the imagick PHP extension

Grab it from here, I used 3.0.1 RC2. Extract the archive, and then execute the following in Terminal:

MACOSX_DEPLOYMENT_TARGET=10.6
CFLAGS="-arch i386 -arch x86_64 -g -Os -pipe -no-cpp-precomp"
CCFLAGS="-arch i386 -arch x86_64 -g -Os -pipe"
CXXFLAGS="-arch i386 -arch x86_64 -g -Os -pipe"
LDFLAGS="-arch i386 -arch x86_64 -bind_at_load"
export CFLAGS CXXFLAGS LDFLAGS CCFLAGS MACOSX_DEPLOYMENT_TARGET

This sets up compilation as a Universal binary. Once the exports are done, execute:

cd /imagick/
phpize
./configure --with-imagick=/opt/local
make
make install

When this completes, you will have a directory called modules, inside which you will find imagick.so, the PHP extension. You can check compilation worked by executing:

file imagick.so

which should return:

imagick.so: Mach-O universal binary with 2 architectures
imagick.so (for architecture i386): Mach-O bundle i386
imagick.so (for architecture x86_64): Mach-O 64-bit bundle x86_64

If it doesn’t, then your exports didn’t happen correctly, and only one version was built.

6. Copy the module to the MAMP modules folder

You now need to copy imagick.so to the folder where MAMP stores PHP extensions, which in my install is:

/Applications/MAMP/bin/php5.3/lib/php/extensions/no-debug-non-zts-20090626/

for PHP 5.3, and

/Applications/MAMP/bin/php5.2/lib/php/extensions/no-debug-non-zts-20060613/

for PHP 5.2.

7. Add the extension to php.ini

Here you can choose to edit the MAMP template (File -> Edit Template -> [your PHP version]) or simply edit php.ini found in either /Applications/MAMP/conf/php5.3 or /Applications/MAMP/conf/php5.2. Add the following line:

extension=imagick.so

8. The Test

The easiest way to see what PHP is being run with is to create a simple php page with:

<?php

phpinfo();

?>

This will show you all the extensions being loaded, and you should see an entry for imagick. If you don’t, check the PHP error log, where you may find crap like this:

dyld: Symbol not found: __cg_jpeg_resync_to_restart
Referenced from: /System/Library/Frameworks/ApplicationServices...
Expected in: /Applications/MAMP/Library/lib/libjpeg.62.dylib

which is Not A Good Thing™. You may also hit library version incompatibilities, such as imagick.so requiring newer libraries than those provided by MAMP. If this is the case, you need to edit MAMP’s environment variables, thus:

sudo vi /Applications/MAMP/Library/bin/envvars

Comment the two lines that set and export the path, which look like:

#DYLD_LIBRARY_PATH="/Applications/MAMP/Library/lib:$DYLD_LIBRARY_PATH"
#export DYLD_LIBRARY_PATH

and add:

export PATH="$PATH:/opt/local/bin"

This has the effect of breaking out of the MAMP sandbox, and using the newer libraries found at /opt/local/bin. You could also delete the originals in MAMP and add dynamic links to the newer versions at /opt/local/bin, but I have not tried this nor recommend it.

After doing this change, restart MAMP, and try to reload the PHP info page – imagick should now be listed and working!

Let me know if I missed anything or you have any improvements to this tutorial, I am by no means an expert at this, just managed to get it working after a bout of severe hair loss.

After an exchange on Twitter during which I stated my views on the Mosque / Islamic cultural center going up near the New York WTC, he unfollowed and blocked me from following him. After posting this on his blog post regarding the subject:

“Now that you have not only unfollowed me (whatever) but also blocked me (?!) on Twitter, I guess it can only mean that I’m a right-wing extremist that hates Muslims and goes shooting traffic signs on weekends for fun. For the record, I’m not trying to give lessons around religious beliefs, and thus will replace the word “Christian” by “other religions” below. Maybe you will find the words more suitable, or maybe you will say “thank you for the lesson in arrogant other religions superiority”.

Instead of trying to prove a point through whatever means possible, and silencing those who do not think the same way as you do, maybe you should try to do a little fact-checking before you post on a sensitive subject.

Cordoba is a city in Spain which was the symbol of Islamic rule over most of the Iberian peninsula (known as Al-Andalus) between 711 and 1492. It is also marked as the origin of the bulk of Islamic law, having hosted a library with half a million books. Calling this center “Cordoba” has very strong implications as to historic and current claims by a sizable chunk of Muslims.

Al-Andalus was established as an independent emirate, which lasted 780 years until it was taken over in 1492. This emirate is the very reason 192 people died, and over 1000 were injured, in the Madrid train bombings in 2004. Islamic theologists hold the theory that any land that once was Muslim, belongs to Islam forever. Thus, there are Muslims who still claim that most of Spain is in fact their land, and will go to violence to retake it. I fail to see other religions claiming that land occupied in past ages still belongs to them, and taking violent actions to re-claim it.

Recently, during the World Cup, 73 people were killed in a suicide attack in Uganda, for the crime of watching soccer. It is considered un-Islamic by some Muslim extremists. I fail to see similar attacks carried out by suicide bombers of other religions, or other religions prohibiting soccer and other forms of entertainment.

When the 9/11 terrorists crashed the aircraft into the WTC, they were most likely shouting “Allahu Akbar”, meaning “Allah is the Greatest” (it’s safe to assume this as we have seen it on countless terrorist attack videos, pre and post event). They were at least certainly not shouting “my superior being from another religion is the greatest”. They crashed those aircraft, and killed those people, believing they were defending Islam. We can argue all we want about wether they were not really Muslims, as some claim, but the fact is that there are -many- people out there willing to kill and die to defend Islam. And they don’t care what religion you follow, or even if you are agnostic, if you are not Muslim, you are an infidel. Your choice is to convert or die.

Having said all this, I do believe there is a large majority of Muslims who are NOT terrorists, who do NOT condone violence, and who would like to see extremism end. What is sad is that they have to endure the wrath of extremists from other religions who cannot distinguish the facts. What is also sad is that once you take sides, even in the most moderate form, the other side (and I’m looking at you Dave) automatically classifies you as the enemy.

As for your arrogant and insulting comment “you have a lot of brothers!” (it became arrogant and insulting once you put it in context along with your other comments and actions), maybe you can drop by Ten House on Liberty Street and ask the guys there to explain you the concept of brotherhood in the fire service. They lost six guys on 9/11, and had their firehouse destroyed. It was damaged again a few years later, during the Deutsche Bank fire where two firefighters also died. Maybe you can also watch the 9/11 documentary, it also provides a good insight into the meaning of brotherhood in the fire service.”

he has now also banned me from posting comments on his blog. Dave, do you consider yourself open-minded, tolerant and willing to respect and discuss other people’s points of view? Or do you simply live in your own world, where the only reality that counts is what you think and write? I think you should get back down to Earth and shed the prima-donna attitude, frankly. What is more amusing is that I’m reading comments on the blog post that are not much different from what I am saying, I guess I have now been moved to the Dark Side of Dave Winer’s world.

The need for speed

The SIM card that your mobile phone is wearing is defined by a set of standards, mostly by GSM 11.11 [PDF] and ETSI TS 102 221 [PDF]. The ISO/IEC 7816-3 standard also defines some of the commands and procedures used by SIM cards.

In essence, a slow-speed startup sequence is performed after the initial card reset, at a preset speed of 9600bps. Yes, bits per second – you may start to infer where I’m getting at. After this sequence, the host is free to clock the SIM card up to 10MHz, which at the defined baud rate of c3/327, C3 being the clock frequency, means it can achieve a top speed of 30581bps. Or 30kbps.

Now correct me if I’m wrong, but bog-standard 3G being offered at 3.6Mbps. Sagem claims they can deliver this to a WiFi chipset on the SIM card…over a 30kbps bus. Somehow, I don’t buy it – and maybe that’s why they wouldn’t show any actual SIMFi cards, and only performed demos on closed terminals. And I bet they used a Sagem phone, and not a Nokia 6110.

InterChip USB to the rescue

IC-USB is an addendum to USB forum’s USB 2.0 specification, which enables USB communication between embedded chipsets at high(ish) speeds, using low power, short distance links. Wikipedia cites the maximum link length at 10cm. Gemalto provides a presentation [PDF] that has some plain-language information on the new card format, and what it can do. Finally, this GSMA document [PDF] provides some background information on the implementation of advanced functionality into new-generation SIM cards. It talks about minimum bus speeds of 200kbps. For the purpose of IC-USB, high speed means 12Mbps, which is respectable for what SIMFi tries to achieve.

Contacts? We don’t need no stinkin’ contacts!

This is what a normal SIM card reader looks like (there are many variations), as found on all phones in the market today:

Note that it has six contacts. The new IC-USB and UICC-ME protocols call for eight contacts on the SIM card, in order to fully accommodate the bus requirements. To put it bluntly, this means that the SIMFi will NOT be compatible with any existing mobile phone, and will only be compatible with phones sporting the new card reader and IC-USB protocol. I imagine Sagem made a phone specifically to work with the SIMFi for demos, but the claims that “In practical terms, this means that you’re able to turn virtually any phone (or “classic handsets,” as the company calls them) into a WiFi hotspot” (Engadget) are wildly over-stated.
