AntiSpam Processing with Mac OS X Server for Mail

We upgraded to Mac OS X Yosemite in December, 2015, installing OS X Server v. 5.0 to handle DNS, Mail, and Web services. We'd been handling Mail services "manually" using postfix, SpamAssassin, and MailServe (by Cutedge Systems) for several years, so there was a bit of a learning curve in switching over to OS X Server. Server uses SpamAssassin (SA), so that was familiar, but X Server runs SA from underneath amavisd.

I happened to mention amavisd and SA today, in Twitter. A friend asked me for details. I obliged by email, then thought, "I should blog this, in case anyone else ever asks".

Looking for Coffee in All The Right Places

Starbucks along101

We occasionally drive up into the North Bay Area (Marin and Sonoma counties) for a concert or some other entertainment. On the way up, we typically get a coffee drink for the trip before heading north. On the way back home, we'd like to do the same; however, our options are more limited in the latter part of the evening.

While there are many Starbucks along that stretch of US 101, only a handful are open after 9pm, which is when we're usually driving home. I decided to look for a list of those stores.

Starbucks has a Store locator that makes it easy to list all of the stores in a given area. I can't filter by "open late", but I could scan for closing times after 9pm. (Note: to do this, you need to use the store locator before 9pm. Otherwise, if the store has closed, the houses will not be listed. It will just say: Closed.) ...

Twitter - Do You Get It?

Many years ago, my sister came home from school and shared a joke a friend had told her. We laughed. Then she told us what her friend said after he told the joke:

"Do you get it?! Do you get it?!

I don't get it."

More recently, a co-worker sent me a link to a question posted at YCombinator Hacker News:

Ask YC: Why should I care about Twitter?
Are many of our news.YC users also Twitter users? What do you find that you like about Twitter?

Reading the comments, I was reminded again that there are Two Kinds of People: Those who "get it" (in this case, Twitter) and those who don't. How can something so apparently simple be so difficult to understand?

Maybe because it's so simple. ...

Now Using Twitterific

I have started following Twitter using Twitterific from The Icon Factory (Mac OS X only). I'm not 100% in love with Twitterific, but I like it well enough to pay the (optional) registration fee. I figure registering gives me a better chance of success when filing feature requests. :-) (Registration also makes the ads disappear.) ...

Lifestreaming with escaloop

lifestreaming n. An online record of a person's daily activities, either via direct video feed or via aggregating the person's online content such as blog posts, social network updates, and online photos.

I don't use Flickr, MySpace, or Facebook, but I have started a lifestream page for my weblogs and twitter streams. I'm using escaloop.

escaloop allows you to build a list of up to 20 RSS feeds -- feeds like your latest bookmarks, your recent Twitter activity, your new blog posts, your newly uploaded Flickr images, just to name a few -- which it will then sort, clean up and tastefully arrange in a concise, neat and pretty list on your own site.

TWiki Community Summit and Meetup


On Thursday and Friday, Feb 14/15, I attended the TWiki Community Summit in Sunnyvale, CA. The location and and wireless internet access for the meeting were provided by Yahoo!. The Summit meetings were followed, on Friday night, by an open TWiki User Meetup.

TWiki Community Summits are organized for TWiki Community members, e.g. core developers, extension developers, doc writers, marketeers and supporters of the TWiki ecosystem in general. Building on the success of the first Summit, held in Rome in August 2007, TWiki community members decided to hold a Summit meeting every six months. ...

I'm a Twitter Twit

Paul Downey writes:

Ruminating on Twitter constraints, I see two kinds of Twitterers emerging: Twits and Twerps.

A Twit sees Twitter as a presence service. Twits love the ambient intimacy twitter affords with their friends, and tweet to build a meaningful permanent record. They strive to entertain, to be profound. ... A twit uses an @reply primarily to reference a user for the benefit of their other followers, and use a direct message to communicate with someone where their followers are unlikely to be interested in the conversation. ... Twits always think about the question “What are you doing?”. A good twit will make you laugh, make you cry but above all feel connected.

TWiki Meetup

Last night was the first Silicon Valley TWiki User Meetup. TWiki is an open-source , open-development, structured wiki, a web-based collaboration system. I've been using TWiki since mid-2006. I work with it a LOT at the Job.


The Meetup was held at the Plug and Play Tech Center (.com) in Sunnyvale. Nice place, if a bit hard to figure out where to park.

There were 50+ attendees. First there was networking and munchies. I networked with the "TWiki" Birdie, a beautiful female White-Bellied Caique (parrot). She's the mascot and "Social Networking Catalyst, as well as a total sweetheart. ...

Introducing Snibbles - A Tumblelog

I've been building a new weblog, called Snibbles. Snibbles is a tumblelog.

A what??

A tumblelog is a variation of a blog, that favors short-form, mixed-media posts over the longer editorial posts frequently associated with blogging. Common post formats found on tumblelogs include links, photos, quotes, dialogues, and video. Unlike blogs, this format is frequently used to share the author's creations, discoveries, or experiences without providing a commentary.

from Wikipedia.

Jason Kottke described tumblelogs as "really just a way to quickly publish the 'stuff' that you run across every day on the web." ...

Twittering: Who, What, and Why

Shortly after I posted my recent entry on Twitter, I sent notes to various e-list groups I read regularly, asking if any of the members use Twitter. A former co-worker replied thusly to my inquiry:

Haven't used Twitter... I think these services are kinda silly. Who cares what I had for lunch today?

Well, that depends. Was it a particularly good lunch? Perhaps at a new and interesting restaurant you would recommend to friends?

Still, if that's your impression of Twitter, you haven't taken a good look at it lately. There's a lot more going on than just "what I had for lunch". ...

JavaScript: The World's Most Misunderstood Programming Language

Douglas Crackford>writes about why JavaScript is actually a much better programming language than most people think. The article is both amusing and insightful.

JavaScript, aka Mocha, aka LiveScript, aka JScript, aka ECMAScript, is one of the world's most popular programming languages. Virtually every personal computer in the world has at least one JavaScript interpreter installed on it and in active use. JavaScript's popularity is due entirely to its role as the scripting language of the WWW.

Despite its popularity, few know that JavaScript is a very nice dynamic object-oriented general-purpose programming language. How can this be a secret? Why is this language so misunderstood?

Excluding Categories in Movable Type

We wanted to be able to post "draft" weblog articles, accessible for review by a selected audience but not publicly available to the world yet. We wanted to exclude one or more named categories from all indexes and lists; however, we also wanted to ensure that the "excluded" articles could be found by direct URL to their "Individual Archive" pages.

We use Movable Type which has many useful plugins available, including quite a few choices for handling categories. That's the good news. ...

Sending Web Form Data by Email

A friend asked me for some software advice:

I need a CGI for taking a simple web form (name, address, phone, email, etc.) and sending the data to a specific email destination in a format that could be loaded into excel or a database. Ideally, I'd like the email address (in the form) validated for basic address compliance.

This would be running on a Mac OS X Server (Tiger) w/Apache, Perl 5.8.6, mod_perl.

I could write that myself, but it just so happens that I know of two programs to recommend. ...

Blogger Meet-up (and I missed it!)

Is the "traditional media" doing anything like this where you are?

The personal media revolution came to the KRON 4 studios Saturday [June 11] when more than 100 members of the Bay Area blogger community accepted [an] invitation for a meet-up.

[ Bay Area Blogger Meet-up ]

KRON 4 ("The Bay Area's News Station") is one of our local television stations and a big player in the "traditional" media channels. I find it intriguing that a television station is interested in connecting with weblogging; I would have expected a newspaper to do something like this.

KRON 4 recognizes the importance of the blogosphere in connecting with our local communities. If you don't have a web log or "blog" yourself, chances are one of your friends or neighbors does. Bloggers take the time to post their thoughts on virtually any subject imaginable. Their efforts are already changing the media landscape.
In the coming days and weeks, will be launching two major new initiatives designed to support the Bay Area Blogosphere. We will be posting and maintaining a comprehensive list of Bay Area blogs. Also we will be launching a new aggregator that will allow you to come to one place to see the latests posts from local bloggers.

Kinda cool...

I missed the meet-up (I vaguely recall seeing and discarding the evite) but I got the second notice, sent both as email and posted on the KRON-4 website. (Hmmm. They found my weblog :-)

They're asking for feedback. I'll have to think about what I want to say.

Grafedia - Grafitti meets the WWW

It's certainly nothing I would have thought of. Words written in blue, underlined, painted on a wall. Use your cell phone or computer to send email or a text message to that blue word "" and get back an image or sound file by return mail.

It's hyperlinking in the physical world. It's weird. It's strange. It's also a really cool concept.

Grafedia is hyperlinked text, written by hand onto physical surfaces and linking to rich media content - images, video, sound files, and so forth. It can be written anywhere - on walls, in the streets, or on sidewalks. Grafedia can also be written in letters or postcards, on the body as tattoos, or anywhere you feel like putting it. Viewers "click" on these grafedia hyperlinks with their cell phones by sending a message addressed to the word + "" to get the content behind the link.

Grafedia was created by John Geraci at the Interactive Telecommunications Program, NYU. It was recently written up by CNN. I wonder if there's any in San Francisco yet...

Men, Women, and Web Services

You've probably heard the statement that when it comes to communication, men are from Mars, while women are from Venus? A concept straight from the title of a book by John Gray, this highlights an idea made popular by Deborah Tannen (You Just Don't Understand) in 1990. When men and women try to communicate, they often seem to be from different planets.

On the other hand, I bet this is the first time you've heard of the idea that men are from Mars, women are from Venus, and web services are from Betelgeuse. :-) That's the title of a paper (in PDF format) that I found while surfing around on the web. The authors extend the theme to the problems of communicating between legacy applications and new Web applications. ...

Comment but nofollow

First it was graffiti on walls. Then it was junk mail,. In the "information age" it's junk faxes and an increasing torrent of undesirable offers in our emailboxes. In the past year, there's been a major increase in the volume of a new kind of graffiti junk spam — weblog comment spam (ich).

Comment spam has lately become more than a minor annoyance for the site owner. But, with the help of other members of the weblogging community, we've been fighting back.

One tool, available for those who use Movable Type, is MT-Blacklist, a plugin that lets you easily manage and delete comment spam. I've been using the Blacklist plugin for about a year now; it prevented the need for me to turn off comments entirely. Even better, as of MT 3.*, comments can now be moderated as well. Between MT-Blacklist and moderating, a lot of my troubles have vanished. ...

IT & Tea - Weblogging Presentation

I attended a presentation on weblogging today. Rich suggested I attend as he couldn't promise a properly complete recap :-)
Speaker: Terry Huwe - Director of Library and Information Resources- UC Berkeley

It seems everywhere you look these days, people are talking and thinking about Blogging. But just how relevant is Blogging? Is it just another "transitional" technology, or is it here to stay? Terry Huwe will explore these questions, covering what Blogs are, how they work, and what their value points are. This talk will explore both the "big picture"--how Blogs fit into the "information ecologies" of today's organizations--as well as the basic technical skills you need to get started. Attendees will learn what the top Blogging products are and how to find out more about them, what's new and emerging in the Blogosphere, and how to make strategic, informed decisions for evaluating Blogging as an information management tool.

The presentation focused on the potential that weblogging has for organizations, such as research organizations, libraries, institutions and corporations, more than individuals. Apparently weblogging has been the hot topic at the last two "Internet Librarian" conferences and the most recent "Computers in Libraries" conference. As Mr Huwe said, weblogs provide fast movement of content to the web without touching a server. "What's not to like?" ...

Weblogging - The Next Generation

I have begun a weblogging experiment.

I created a private weblog for my family, a kind of Family Bulletin Board. Then I invited 10 family members to join as Guest Authors. So far, 5 of the 10 have accepted the invitation and one is considering the idea. All of the guest authors have posted at least once and several have also added comments.

In addition, my sister has been sufficiently interested to ask me to help her set up her own, personal, weblog. Now that's a success story.

TypePad is in sight

When I first started playing with weblogs, I used Greymatter. I didn't do much with it, and things just sort of lay fallow for about a year. Then I heard about Moveable Type at the O'Reilly Mac OS X conference and (eventually) got around to installing Moveable Type in February, 2003. I really like MT and I've been steadily adding to my journal ever since.

Fortunately (for me) but unfortunately (for many potential users) MT provides a wealth of options for configuration, most of which require a knowledge of HTML coding to use! To address this "problem", the developers of MT have announced (and will soon be releasing) releasing TypePad. ...

Safari has Tabs!

The latest Safari beta has tabs! It has AutoFill as well. My first and second most desired enhancements are now part of Safari. My new favorite browser now has everything I wanted!.

Tabs have been a big deal since Safari shipped the first Beta. There are Tabs in Mozilla and (most) users like tabs (count me among them). Giles Turnbull wrote an article comparing Safari to Camino (formerly Chimera), the Mac OS X Aquatized Mozilla project. He wrote:

No sooner had Safari made it out into the wild, than many users were clamoring for tabbed browsing. Long available in Mozilla, Opera, and other browsers, the use of tabs to bring together a screenload of web browser windows into a smaller, single-window package has become a very popular feature (although there are some who consider tabs alien to the Mac way of doing things).
