Blue Security: Use a Frog to Fight Spam

2006-01-01T00:26:00.000+02:00

Everybody hate spam. I bet even the spammers themselves do. It's one of the highest-rated Internet annoyance. It is generally listed together with spyware and pop-up ads, but to me it's much worse. Avoiding spyware is easy (use Firefox and trust no one); avoiding pop-ups is even easier (use Firefox or one of the many IE toolbars that block them).

But spam... that's a different beast. Right now even the best filters miss some messages, or worse - mistake legitimate messages for spam (false positives). At my work there's a corporate spam filter installed on the mail server, and I still get a few spam messages a day.

Now there's a company that tries to fight back. They are called Blue Security, and they operate the "Do Not Intrude Registry". You should read their solution overview, but if I get it correctly, this is how it works:

You install a small agent called "The Blue Frog" on your PC (there are versions for both Windows and Linux);
You forward spam messages you get to Blue Security;
They (a team of real people) analyze the messages;
Using the Frog on your machine, they send complaints to the offenders.
In addition, they send complaints to government agencies and ISPs (for example: stock-spam is illegal, and so is selling prescription drugs without a doctor note).

One nice thing about this service: if you're willing to run the "frog" on your machine, you get the service itself for free. But if you're a business and don't want to install stuff on your machines, you can pay them instead and get the same protection.

Anyway - I like this idea, and hope this works for the long term. It will work best if many people will join, so I decided to put a permanent link to the company's site on this blog. I want to encourage all my readers to join.

Before you ask: yes, the link to the right includes a "referrer id". But no, they don't pay me anything for that. I really do want more people to join, because I'd like a spam-free mailbox. It's just like my Firefox link.

- Noam.

New site popularizes feed icons

2005-12-24T11:52:00.000+02:00

The Firefox feed icon (see below) is going to be the new de-facto standard for feed icons - for both RSS and Atom feeds. A new site, Feed Icons, has been set up to popularize the icon and provide high-quality versions of it.

Performancing: blogging extension for firefox

2005-12-20T23:02:00.000+02:00

This post is edited and published from Performancing for Firefox. This is an extension for blog publishing, straight from the browser - without going to blogger.com first. It's way cooler than Google's "Blog This!".
It also allows me to see (and edit!) previous posts - and almost completely replaces Blogger's dashboard. Very nice UI!

Still missing: a spell checker.

Thanks, Asa, for the link.

Firefox Extensions

2005-12-04T23:15:00.000+02:00

I'm trying to think of creative uses for del.icio.us tags. My first one - that's also practical - is recommending Firefox extensions.

I have tagged the installation pages of my favorite extentions as my-firefox.

Moving my paper

2005-12-03T15:25:00.000+02:00

The problem with finishing college, is that they don't let you keep your home page. At least that's the case in my college.

So as of now, the paper I wrote with Dr. Iaakov Exman, "Compact Comparison of Competing Software Designs", is hosted in Yahoo!'s Geocities instead.

Update, 29/Apr/2006: another copy can be found in Google Pages.

Google Analytics: Flash?!

2005-12-02T23:42:00.000+02:00

Google's Web Analytics service seems very nice. It's a well-done AJAX application. Except that...

Some parts of it use Flash instead of JavaScript. This is strange, and doesn't fit the current trend (across the Web and in Google's sites).
One of the features is a map - you can see where in the world your visitors come from. The big surprise here, is that it doesn't use the Google Maps API. Instead it uses... A FLASH map!

I'm almost certain this is just because they bought the software (from Urchin), and that they're going to "fix" it to be a regular AJAX app that uses Google Maps.

- Noam.

Google Analytics

2005-11-15T11:13:00.000+02:00

Google has just launched Google Analytics a web site traffic analysis service. They offer it for free. It is based on software from their recent acquisition, Urchin.

I just installed it on this blog, to check how good it is.

Google has launched a blog-search tool

2005-09-14T18:14:00.000+03:00

Here.

Is that the end of Technorati? I hope not, I kind of like it.

I guess now Yahoo/AOL/MSN will buy them.

Google Suggest for Firefox

2005-07-23T12:26:00.000+03:00

This is really cool. If you use Firefox (which you should) and Google - and you like Google Suggest - you'll love this new Firefox extension from Google. Google Suggest for Firefox integrates Suggest into the Firefox search box. The result is really nice.

Music: Live8, AOL, Yahoo!

2005-07-23T01:39:00.000+03:00

If You like music...

AOL has the entire Live8 show online, on-demand. The quality of the streaming video is pretty good. You can select any played song, and just view it within seconds. I couldn't get it to work with Firefox though - only IE.
Yahoo!'s LAUNCHcast service is very nice. Basically, you select your favorite artists and genres, and let the system play songs that much your taste. And when you hear new content, you can rate it - and the system learns your taste better. The best thing about this service - it's free. The second best thing: you get to know new artists.

Enum Code Generation

2005-07-01T14:49:00.000+03:00

Once you start playing with code generation, you can't stop. At least, I can't.

One of the new features in J2SE 5.0 (or 1.5) is enums. I've missed enums for a long time, and I usually used the unsafe "static int" enums when I had to use them. The new version of Java provides real, type-safe, enums - but unfortunately, I can't use it, because I code for an old version of the language.
So I developed my own type-safe enums, based on Joshua Bloch's suggestion from the Effective Java book.

My idea is to describe the enum using XML, and then use XSLT to translate it to Java. The XSLT stylesheet adds all the boilerplate code required by type-safe enums.

One advantage of using XML+XSLT is portability between languages: at work, I build a Java component of a mostly-C++ project. The other engineers in my group have defined their enums in C++, and currently, to communicate with their code, I have to manually update my enum with theirs. If the enum is defined by using XML, we can write another XSLT that translates it to "regular" C++ enums.

I will publish my XML format + XSLT translator here, after I clean it a bit.

Gmail vs. Blogger Composer

2005-06-25T17:02:00.000+03:00

Speaking of Gmail: I wish Google will unify the Gmail and Blogger message/post composers. They are almost identical, but each of them has its advantages:

Gmail: looks better. The "font" and "size" selectors are smaller (better). Better speller.
Blogger: Allows images to be inserted to the post. Allows HTML source editing.

In Gmail, you can only insert an image that is already hosted somewhere on the web (like it used to be with Blogger). You add an image by dragging it from a webpage to your message. You cannot however embed an image that is attached to the message.

Gmail subdomain changes

2005-06-25T16:49:00.000+03:00

It seems like Google is changing Gmail's subdomain from gmail.google.com to mail.google.com. When you go now to http://gmail.com you are redirected to http://mail.google.com/mail - instead of the regular http://gmail.google.com/.
For a few minutes the gmail.google.com domain was unavailable, now it redirects to the new subdomain.

I wonder if it means anything about Gmail's name. Will they change it from Gmail to Google Mail?

Anyway, they'll have to update their help item about phishing to reflect this change, or some people will mistake them for phishermen...

Google adds image upload to Blogger.com

2005-06-25T12:37:00.000+03:00

Finally, Blogger.com users can easily upload and add images to their posts, without using 3rd party image hosting solutions. This was only a matter of time, after Yahoo! had acquired the service most used for that purpose among Blogger users - Flickr.

Finally, the Final Project is over

2005-06-23T19:24:00.000+03:00

I'm happy to say that my Final Project, on which I blogged here in the past, is done. The project is a Statecharts code generator and simulator suite. It uses technologies like XML, UML, XMI, XSL, Java, Swing, and more. Yes, it is fully buzzword-compliant ;-).
The project was built for a large high-tech company, and by their requirements. It was very interesting to design and implement. The only "problem" is that now I have to write a report about it, for the college (Jerusalem College of Engineering).

Since the project itself is not yet production-quality (more like an initial alpha), it requires more work. And since I already work for this company (although on a different project), I might help in its future development.

Bruce Eckel on Object Design

2005-06-17T15:11:00.000+03:00

If you're into Software Engineering (like I am), you'll be interested in reading Bruce Eckel's blog post on Object Design. He writes (also) about how people confuse abstraction layers, and how the UML doesn't help in this field.
I also wrote a comment in the thread, which I'll duplicate here (but first read the original post):

I'm a Software Engineering student - graduating in a few weeks. My final project is a Statechart code generator + simulator for a high-tech company.
Interestingly, I had two problems with UML while developing the software:

1. The designer of the statecharts I had to generate code from uses UML it in a very abstract manner. For example, in actions he doesn't call real functions - he just puts some text that will mean something to someone. That's because this is the company's first attempt at code generation - and the designer "knows" that a human will read the charts and translate them into code (and not a computer).

2. When, in the middle of the year, I had to prepare UML diagrams to document my own software, I found it impossible: most work (code generation) was done in XSLT, which is not OO - so I found no matching UML diagram. Instead, I came up with a DFD that shows what my software does. Since DFDs are not part of the UML, and because I found no open-source DFD diagramming tool, I had to use... PowerPoint!

For fixing the first problem, I wish UML tools had "design modes", something based on Fowler's UML Mode (http://martinfowler.com/bliki/UmlMode.html) referred-to earlier in this thread. That is, in the "sketch" mode, the tool will hide those detailed-design features of the UML (like composition/aggregation). When running in "programming" mode, users will be able to add these details to the model. Later, when the high-level designer edits the model again, those features will be hidden - but will remain in the model. I realize that doing this correctly is not trivial - it's in my wish-list nevertheless.

The second problem is different. UML is for OOAD, not procedural/functional design. But there are still projects that use the older methods. What diagrams should they use? In my college, they teach UML thoroughly, but say next to nothing about the other options - as if one should never develop non-OO software.

The Search Engine Relevancy Challenge

2005-05-14T11:48:00.000+03:00

This is interesting. RustySearch allows a "search engine blind test". You enter your keyword, and it queries - in random - one of Google, Yahoo, MSN, and Ask Jeeves. It then displays the results, and allows you to rate them (1 to 5) - without telling you which engine it came from. Results from all engines are using the same template.
There are also initial results (they are not displayed in real time), after 5,000 votes:
1. Yahoo (3.4287)
2. Google (3.3668)
3. Ask Jeeves (3.2602)
4. MSN Search (3.0855)

Google Web Accelerator

2005-05-07T14:42:00.000+03:00

So, Google wants to be the world's web proxy server? I don't think it's such a good idea. Why? Well, start with thinking on why they want it. They want to know more about web users. Much more. If you use GWA, all of your web traffic goes through their servers. They will know everything about you, maybe even more than yourself - because they will have the chance to analyse your behavior.

They say they do prefetching. Firefox does that, and only when appropriate (i.e. when the website uses a special html attribute). They say they compress the data sent. Well-configured web-servers already do that. And the mere functionality of a proxy server, in the past, was the responsibility of ISPs.

Plus, when yesterday I installed it - just to check it out - it killed my Firefox. I had to uninstall GWA, then restart Windows, to be able to use Firefox again. I have no idea why, but I saw another user complaining about it in slashdot (and another one in a blog comment).

I may try it again after, in a few version, Google fixes some bugs and clarify their intentions.

Nathan Weinberg puts it all together on his excellent Blog News Channel.

Is software engineering, math, science, or what?

2005-05-04T17:38:00.000+03:00

There seems to be a debate going on in the Software Engineering world, about whether SE is really Engineering. I don't know who started it, but it's interesting.
First, Allen Holub writes "Is Software Engineering an Oxymoron?". Then, as a reply, Jack Ganssle writes that "Software engineering is NOT an oxymoron". I tend to agree with Holub, but not entirely. They both have valid points.

In Artima, there's a discussion on the above articles.

Finally, there's this apparently unrelated article written by B. Jacobs, titled "Computer Science" is Not Science and "Software Engineering" is Not Engineering . I'm about 90% with him. A fascinating read, about 10 pages.

Firefox 1.0.x was downloaded more than 50,000,000 times

2005-04-29T22:10:00.000+03:00

Two or three years ago I "found" a new web browser called Phoenix. It was based on the Mozilla rendering engine (Gecko), but was much smaller. I gave it a shot. I liked it, but it wasn't enough for me, so I uninstalled and forgot about it.

Some time later, I saw another new browser, also based on Mozilla. This one was called Firebird. Only after downloading and reading about it, I found out this was actually a new name for Phoenix. This version was much better (as far I as remember) than the Phoenix, so I kept it.

I updated Firebird with every minor version. One upgrade suddenly changed the name to... Firefox. Whatever. Firefox was a really good browser, so I stopped using MSIE (*).

I followed Firefox with anticipation through all versions. I was really happy when version 1.0 was out, and installed it on every computer I go to (work computers, friends computers, etc).

And now - 50 million is a real milestone. Wow.

Congratulations, Mozilla developers! Thank you, and keep up the good work!

(*) Except for annoying sites that won't render correctly in non-IE browsers.

Gmail Blacklisted by SpamCop.net

2005-04-23T13:33:00.000+03:00

Gmail's SMTP (outgoing) mail servers seem to be blocked by SpamCop.net. I keep getting failure messages from servers I try to send mail to.
See:
SmapCop.net checkblock

This means that Gmail users (at least in my cluster) can't send mail to servers that use SpamCop's blacklist. I've notified Gmail, and I wait for them to take action.

The Eclipse Modeling Framework

2005-02-26T01:25:00.000+02:00

I've downloaded EMF, and I'm trying to figure out how it can help either my final project or my work in general (at work I also use Eclipse). I like the fact that it can generate a model from Java source code, but I wish it could also generate a Rational Rose model.
Can it do that?

My Final Project

2005-02-21T19:55:00.000+02:00

Today I had a presentation-exam about my project. I talked about my progress and my future work. It went pretty good, but I didn't get a grade yet. It is expected in a week or so.

To summarize:
My project is about code generation from UML statecharts. Using Java and XSLT, I take the XMI that represents the statecharts, and generate a QHSM state machine in Java/C.

Confused? Sorry. I'll try to explain:

Statecharts are a graphical representation of complex systems. They are based on finite state automata, but extend (and complicate) them greatly.
UML is the Unified Modeling Language. It is a graphical language that allows software developers to describe their software designs in a visual way. Statecharts are a part of UML. There's a FAQ about UML here.
XSLT is a language for transforming XML into other text, including other XML. Here's a tutorial.
XMI (the XML Metadata Interchange) is a representation of UML data (and some other metadata) in XML format.
QHSM is "Quantum Hierarchical State Machine", which is Miro Samek's implementation of a state machine (a state machine is an executable statechart). It is described in his book.

If I'm not clear enough - please post a question as a comment below, and I'll elaborate on the topic of your choice.

For implementing both Java and C code generation, I use something like Martin Fowler's Two Step View pattern (I was actually told that there exists such a pattern right after I suggested my approach, which I though to be original) - first, I create an XML pseudo-code state machine. Then I take this XML and turn it to either a Java or a C state machine.

It was fun, and I learn a lot, especially on XSLT and XML. I have more things to do for this project. Among them:

Implement the C code generator - at the moment I only have a Java code generator, because that's the main priority of the company for which I develop the software.
Build some king of testing tool, that can take events from a script file and fire them at a running machine.

This Blog is Still Alive!

2005-02-06T16:21:00.000+02:00

I have not abandoned this blog. I'm still here. It's just that I'm very busy - work, exams, and the project are killing me. I'll be back.

Re: Site Statistics

2005-01-21T18:28:00.000+02:00

In a previous post, I said I'm about to compare three site statistics tools. I installed all of them on my blog, to see which service offers the best deal (for free, that is). Well, I think we have a winner.

3rd place goes to RE_INVIGORATE. I'm sorry guys, I really wanted this service to get the first place. The interface is just horrible. Simple thing are made obscure. Sorry, but no.

2nd place: Site Meter. They are the first service I tried (just because they were listed first on this page). They have a very nice service, but they don't give enough of it for free. For example, if you want to see which search queries people used to get to your site, you have to pay for that (or analyse the referring URL yourself).
Site Meter also makes you put their logo on your site, which is sometimes annoying (because you have to find a spot for it in the site template).

The 1st place goes to StatCounter. Why? I like their business model: they offer all services for free, but a free account has two basic limitations: (1) Up to 7,000 (or was that 9,000? I can't remember) hits per day (which is more than enough for my humble blog) and (2) They only store the details (IP, referrer, etc.) of the last 100 visitors.

When you get bigger, and start making money from your site, you just upgrade your account to get rid of those limitations. I like that approach.

I will soon remove the images of 2nd and 3rd places from my template. Feel free to suggest other such free services. Only services that don't require banners/popups are welcome.

Quantum Computers

2005-01-13T21:12:00.000+02:00

Lately I'm into Quantum Computers/Computing/Computation. I've heard about this issue a few times in the past (once when it was mentioned in slashdot, once more when I read the book "Practical Statecharts in C/C++: Quantum Programming for Embedded Systems" which is related to my final project (the book is not about Quantum Computing).

I know almost nothing about Quantum Mechanics, but being a 4th-year Software Engineeting student, I know a lot about Computer Science. So I was looking for an introductory article that will explain QC to computer science people, without assuming we know anything about QM.

I found a few, but somehow they are not enough for me. The first one I read was Quantum computation: a tutorial by Samuel L. Braunstein. I undertood most - but not all of it, because it doesn't get enough into details IMHO.

Statistics: SiteMeter vs. StatCounter vs. RE_INVIGORATE

2005-01-08T15:52:00.000+02:00

When I first set up this blog, I registered with Site Meter to monitor the traffic. Their service is nice, robust and free, but somewhat limited. So I started looking for alternatives.
I found two "good enough" free alternatives:

StatCounter - this service is free for sites that get up to 9,000 hits per day. Good enough for me. The service provides you all the details you need, including referrals tracking and search engine keywords. The only drawback I found so far - they only keep a log of the last 100 users.
RE_INVIGORATE Data Archiving Services - this site looks somewhat hackish, because of its design. They offer a totally free service, but it seems limited in comparison with StatCounter.

I now have all three in my template. After a while, I'll decide which is the best. Since I operate this blog for fun, all I really care about is how many people read each post and what made them come to my blog.

XML tools - my choices

2005-01-08T13:45:00.000+02:00

In a previous post, I wrote I was looking for XML tools. Well, here's what I use:

Eclipse with the XMLBuddy plugin. XMLBuddy has a free version, and this is what I use most of the time. I can't afford the full Pro version for this project. What I like about XMLBuddy (other than that it integrates smoothly with Eclipse, which I use for Java) - is the auto completion feature. I know, all decent XML editors have this - but this one is an Eclipse plugin.. ;-)
XMLSpy Home Edition. It has much more features than XMLBuddy, but it's also much bigger in installation size. Besides, there's something wrong about the auto-completion feature: it lets you choose between ALL XML elements, not just the ones that match the context (according to the DTD/Schema). I use XMLSpy mainly for XSLT.
JAXP... sort of. My project will use Java to turn XMI statechrts into C code. So I'll use J2SE's built-in XML support, because it's pretty flexible.

I'm still looking for other, Open Source, XML editors.

Faster PDF Reading

2005-01-01T21:04:00.000+02:00

Adobe just released Adobe Reader 7. I don't know about new features, but like Asa Dotzler wrote in his blog, the startup time is much, much faster than the previous version(s). If you're a Windows user, you must get it, even if you only view one PDF file a week.

Searching the Web without Google

2004-12-31T21:39:00.000+02:00

This may come as a shock to many people, but pay attention: Google is not the only search engine. I repeat: Google is not the only search engine.
Yes people, there are other search engines (there are even others, but these are the top 3 - after Google). When I started using the Web, back in '97, AltaVista was the "standard" search engine. Everybody I knew was using it. Yahoo's search was powered by AltaVista, until they invested in Google and started using its search. MSN? I don't remember what it was, if at all.

Now, it's not that I don't like Google. And it's not that this 8-minute video-flash movie had such a great effect on me. There are two good reasons to use other search engines:

Having only one search engine is bad. I don't like a single company to control all information. Alternative engines will not exist if we don't use them.
Sometimes, the other engines have better results. For example, when I searched for a PDF of an academic paper, I couldn't find it with Google. But AV did find it. People (me included) sometimes think that if Google can't find something, it does not exist. This is not true.

I'm not saying we should abandon Google. Not at all. I like Google, as I said, and I like Blogger and Gmail. But it's good to know and use the alternatives as well.

More Gmail Invites

2004-12-27T16:19:00.000+02:00

I just got 6 new Gmail invitations. Since all of my friends (and their friends) already have accounts, I have no use for the invitations. If you want to be invited, add a comment to this post. Don't forget to specify your email, in a spam-protected format.

Dilbert's TTP Project

2004-12-24T23:53:00.000+02:00

The Wikipedia articles for recursive acronym and RAS syndrome mention a Dilbert strip "in which Dilbert states that the TTP project refers to The TTP Project".
I wonder where I can find the actual strip. I added notes to the discussion pages of those articles, but no one has answered so far.

The Google Grid, EPIC 2014

2004-12-24T15:13:00.000+02:00

This Flash video, which I found out about via InsideGoogle, is creepy. It talks about what will happen to the media in the next ten years. You have to see it, it's about 8 minutes.

sms.ac: free SMS?

2004-12-17T23:56:00.000+02:00

Recently I got a few invitation-messages on behalf of people I know, to join the sms.ac community. It's supposed to be a site that lets you send free SMS messages.
I ignored the invitations at first, because they looked phishy. But after about 5 invitations, all from different people I know, I got curious, and decided to check it out. After all, I thought, the site already has my email address (it was a Yahoo! Mail address, but I also got one invitation to my Gmail account) - people I know gave it to them.

So I clicked the invitation link. After filling-in the standard details (as well as my mobile phone number), I was surprised to be asked for my Yahoo(!) password. Why would sms.ac want my password?
They want it, because they want to read my address book, and send invitations on my behalf to all my contacts. Then it hit me - all the people that "sent" me invitations actually gave away their mail account passwords!
Does this count as a virus? I'm not sure. The users who did it, gave their password. The site didn't steal it from them. In fact, it said it will invite their friends.
It seems like a clever way to collect confirmed email addresses. Every user that gives his/her password, gives his friends' mail addresses. What does the site do with the information? According their privacy policy, they probably sell it to "affiliates".

I am not a lawyer, but this service is probably legal, becuase they have the users' consent to do what they do. Yet, it's really annoying.

By the way - the main reason people sign up to the site is the promise to send free SMS messages. Well... I tried sending a message after signing up (I signed up without giving my password, it was not mandatory), but it didn't work. It said they don't support my cellular network - but my network is in the list of supported networks.

Beware of phishermen!

Gmail Live Bookmark

2004-12-17T01:11:00.000+02:00

I'm not sure it's new, but I just noticed that Firefox now displays the Live Bookmarks icon when I view my Gmail inbox. The feature itself is not new - Gmail has had an Atom for a few months - but the link is new (Live Bookmarks are "discovered" through a <link> tag in the html header).
The feed has the list of unread messages in the inbox. Firefox displays only the subjects, but proper feed readers (or feed reader extensions in Firefox) can show the sender's information, as well as a snippet.

UPDATE: If you look for Gmail invites, see my other post.

XML Tools

Since my project involves XML, I'll need some XML tools. Mainly, a free Windows/Java IDE. Something with XSL and Schema support. Any recommendations?
I've downloaded the Home Edition of XMLSpy, which looks pretty nice, but I was hoping for an open-source tool.

More Google Suggest

Apparently (and as expected), Google Suggest does not update in real-time. When, for example, you want to see what's the most searched-for Google service (and so you type "google " into the box) - not only the much-hyped Suggest is not in the top 10; when you add "suggest" to your query, you find that people search for "google suggest a site" more than "google suggest"...

I guess the "most wanted" list only gets updated when the index does, because "google suggest" has no matches. In fact, there is no information for that URL.

Site-Flavored Google Search

This search was costumized to my interests.

Google Suggest

Google has released (as a beta, under Google Labs) Google Suggest, which is really cool. You start typing a query, and you get the most popular matching queries in a pseudo-combobox. This is cool, because it allows you to see the most popular searches starting with the letters you typed. So, for example, you know that Firefox is more popular a search than, say, free.

You can also get the most popular RFC documents. The most searched for, as it turns out, is RFC 1918 - Address Allocation for Private Internets. I know that, because I typed "RFC " (without quotes, with the extra space), and it came first.

Final Project

This year I'm developing a software project for a Hi-Tech company in Israel. The project involves generating C code from UML statecharts.

Compact Comparison of Competing Software Designs

ABSTRACT of this paper:

The numerical Traceability Matrix of a given software
system is a compact representation of the system design in
terms of software components. It is a much more powerful
design tool than a checklist as it has been used so far.
Two competing designs are equivalent if and only if their
matrices can be put in identical form. The most modular
design is that with highest computed diagonality.
The paper discusses case studies illustrating these claims.

IEEEI Conference Paper

Today, on the 23rd IEEEI Computer Conference in Herzliya, I talked about a paper I wrote with Dr. Iaakov Exman. The paper, "Compact Comparison of Competing Software Designs", talks about comparing the modularity (among other aspects) of designs by looking at their traceability Matrices.
