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.

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.

I hope I can keep updating this blog. It's fun.

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?
