Reflections on Man United, iCal, and a life well lived

Category : Commentary/ManUtdiCal.txt

I thought there would be something like this - Manchester United's fixtures on iCalShare.com (where you can also find Arsenal's fixtures if you follow the gooners). This is what I now have on iCal.

It's wonderful - iCal displays the time as local time, from whatever locale you view the calendar. No need to check the newspapers or guess if it's a Wednesday or Thursday morning that United is playing.

See what I mean about how the technology is helping us to merge work life with the rest of our lives.

The calendar with the orange tab, above, shows the Singapore Public Holidays. You definitely don't want to schedule a business meeting on a holiday. And my wife updates an Appointments calendar for me, when she needs me to know when I have things to do for the family. I also publish my work calendar, of course, so that's where she goes to get an idea of my schedule.

It's all very easy to set up, if you have your own server. iCal calendars are published using WebDav servers and it's not that difficult to turn on WebDav support using the Apache web server that Apple builds into every OS X machine.

It's the little things that count, and these little things do add up to quite a lot, if what you're looking for is a quality life, or a life well-lived.

I was reading this review of the Mac by a "die-hard" PC user, the other day. It's interesting reading, if only to understand how PC users think and it'll be a useful reminder for when I'm teaching our OS X courses. A PC user is very concerned about speed - e.g., how fast a window opens or scrolls - but what I observe is an absence of context.

Context is what your inner eye is looking for when you think about what you want to do with the machine. For example, using iCal to coordinate a family's schedules. Or using the Font Book, below, to organise the typefaces on my Mac, so that I can use them to add colour to the messages I'm trying to communicate - on a web page or on a piece of printed page.

I love reading Allan Haley's "The A B C's of Type" and I often have it by my side when I work. I've created a collection containing some of the typefaces that Allan Haley covers in his book and I can make them available with just one click in the Font Book.

But I digress. Yes, the Mac may be slower than a PC when it scolls or opens a window. But I don't often notice it because my mind's usually on the context, on what I'm trying to communicate or achieve, and what I can tell you is that the Mac's usually faster than the time I take to find solutions or ideas. Context is the key. Without it, we're always going to be pointlessly arguing about the merit of one tool or the other. With it, the choice is so clear - at least to me.

ISP blocks port 25? No problem

Category : Technology/Port25.txt

Ronnie Teo found the solution to a problem that quite a few people have encountered - the case of an ISP blocking port 25, the default port that mail servers use to contact each other. This is what he says :

Just to share with you some good news. �My Tarawerkz.com mail server is up again. Finally. �The mailhop relay service offered by Dyndns was the solution. �This was what I had to do:

1. In Custom Postfix Settings (in Postfix Enabler, below), two parameters were added: soft_bounce=no, and, unknown_local_recipient_reject_code=550

2. On the Dyndns website, I chose an alternate port on offer from a list including 24, 25, 587, 2525, 10025 and 52525. �I chose 587.

3. Then I forwarded this port on my Linksys router.

4. Lastly, I went into master.cf file to add a line to make postfix listen on the alternate port 587 (instead of just SMTP 25 port)

That's it. �The last thing is to wait. �I thought it didn�t work initally because nothing happened. �Then this morning when I came to the station, all the incoming mail sent over the the last 4 days were there (including the one from Hai Hwee); all automatically retrieved by Spamfire.

Now I am happy and relieved and I have you to thank for it. �So, thanks again.

Thanks for sharing the solution, Ronnie. For point 4, the line to add in the /etc/postfix/master.cf file is :

587 inet n - n - - smtpd

There is already a line that says :

smtp inet n - n - - smtpd

so you add the 587 line to it.

As Ronnie mentioned, you can chooose to use 24, 25, 587, 2525, 10025 or 52525, if your ISP blocks more ports than port 25.

I'm thinking of making this even easier to do by incorporating it into the Postfix Enabler interface - probably the version that I'm preparing for Tiger. But, for the moment, this looks easy enough to do, manually.

So, there. I ought to look into all my mail about Postfix Enabler and do an FAQ. Oughta. Shoulda. Gotta find the time.

Postfix Enabler speaks Italian

Category : Technology/ItalianPFE.txt

Thanks to Joram and Daniele from the University of Rome's Mac Users Group (MugRoma), we've got an Italian localisation for Postfix Enabler.

Postfix Enabler 1.0.9 now works in English, French, German, Italian, and Traditional Chinese.

A Correction

Sorry, I made a mistake. Matthew Hall doesn't write TheJouleBlog. He sent me the permanent link to the IMAP+Fetchmail article and I made the wrong assumption.

PacNet is so slowwww today

Category : Technology/pacnetslowDNSaddresses.txt

Seems like a day for short posts. PacNet users who are seeing a slow-down in web access to sites outside Singapore should add these two IP addresses into (and right at the top of) the DNS field of their Network Preferences set-up : 203.120.90.40 and 192.169.33.3

Looks like they're having problems with their usual DNS servers. These alternate DNS servers help a whole lot. Just don't tell them you're using a Mac. If you're unlucky to get a PC-centric support person, that's the first thing these guys always think is wrong.

If you don't want to be thrown red herrings, always tell them you're using a PC and then translate their instructions into the equivalent (and often shorter) concepts on the Mac.

Though it's somewhat self-defeating in the sense that it will only confirm, in the minds of these PC-centric techies, that the world only consists of PC Windows users.

Postfix Enabler and Tiger

Category : Technology/PostfixEnablerforTiger.txt

And I can confirm that Postfix Enabler doesn't (yet) work with Tiger. Just tried it. Seems like quite a few things to fix. I say it because I've been asked (a few times). I'm sure I can get it ready when that cat comes out to play. Enough of that T word, for now.

Postfix and Software Update

Category : Technology/PostfixSoftwareUpdate.txt

I read elsewhere on the web that Postfix was updated by the latest Apple Software Update. But I've had no problems after doing the update.

So, if you're wondering whether your Postfix Enabled-mail server would go right on working through all the latest updates, have no fear. Just do it.

That's why it pays, as a strategy, to use as much as possible of what Apple puts into the system. Never try to replace things like Apache, PHP, Postfix, etc. with your own versions, if you can help it. You'll spend a lot less time fixing the system, and more time just using it.

Postfix Enabler, IMAP and FetchMail - A How To

Category : Technology/IMAPandFetchmailAgain.txt

This is a follow-up to an earlier post about Postfix Enabler, IMAP and FetchMail.

To recap, if want to use Postfix Enabler to set up an IMAP server and then use Fetchmail to pull down mail from a variety of other servers (so that you can re-distribute them to all your IMAP clients in a consistent manner), here are some instructions on The JouleBlog that can send you on your way.

Matthew Hall writes The JouleBlog and he's sent me a permanent link to the article. I'm making a note of it here because I ought to try this someday. Thanks, Matthew.

The Speedtouch ST570 All-In-One Wireless Modem

Category : Singapore/Singtel1500wirelessmodem.txt

In case anybody is thinking of trying it out, I've upgraded to Singnet's 1500 kbps plan from the 512 kbps plan and got a free Speedtouch ST570 ADSL All-In-One wireless modem, which includes installation.

Of course, the Singtel counter staff will say they're not sure if it'll support the Mac. (Note that this is already better than it was before, when you get a flat-out "no, we don't support the Mac, and probably never will"). So I just said that I was using a PC, and did have a laptop ready.

After the technician finished his installation, and got my laptop connected to the wireless station, I showed him how much faster I could get my iBook up and running and doing the same thing (it took a lot less steps than what he needed to do with my laptop - he had to go to the command line on the laptop and I was wondering how any ordinary PC user would know how to do ipconfig / release - or something like that).

So he said he was very impressed. He didn't know the Mac could do all that, and that it was all so easy, and that he's going to consider buying an iBook, too. He could do all those Unix stuff (plus iTunes and all that, of course).

Installing the wireless modem from scratch looks easy enough, if you want to do everything yourself from the Mac.

So, just in case the Singtel counter staff tells anybody differently, the modem does support the Mac (though it's 802.11/b rather than g, i.e., Airport classic rather than Airport Extreme, but it's free and that's probably good enough).

And it's freed up my Airport Express. There are a few things I mean to try out now that I can move my Airport Express around.

A Map Plug-In for Address Book (for Panther users)

Category : Technology/addressBookPlugIn.txt

I've created an Address Book plug-in for Singapore Maps (based on Stephen Wither's WhereIs plug-in for Australian Maps).

From Panther (OS X 10.3.x) onwards, Apple's engineers gave Address Book users a new ability to work with plug-ins. And smart people are starting to exploit it.

I modified Stephen's AppleScript code and made it work with Singapore's streetdirectory.com. I also wrapped a one-click installer around it.

The installer looks like this and you can download it from here.

Once you've downloaded and installed the plug-in (you can choose to install it at the system level so that it'll work for every user on your Mac), you can go over to Address Book and find a new function in the pop-up menus of Address-related fields :

Choose "Singapore Maps" and your browser will launch streetdirectory.com and point you towards where that address is in Singapore :

Please note: you've got to store your STREET field in Address Book in a regular way - "3 Shenton Way, Shenton House #11-05/06" - i.e., Block No. first, then Street Name, and (very important, don't forget) the comma (or a carriage return), then Building Name and then Unit No. for this to work. You need the comma or carriage return to separate the Street Name from the Building Name.

Neat, right? I've always wanted to be able to do this. This makes Address Book so much more useful.

With AppleScript, and the ability to extend Address Book with plug-ins, and the ability to move the information around to wherever you want it using either Apple Scripts or Unix shell scripts, the things you can do are limited only by your imagination.

Thanks, Steve Withers, for the use of the code.

Byzantium

Category : Commentary/Byzantium.txt

I've come to the last page of A Short History of Byzantium by John Julius Norwich. I must confess that I bought this book for its cover and hadn't expected to enjoy it quite so much. It's got nothing to do with Macs, business or technology, but it's a good book to start with if you're interested in delving further into the history of the Balkans and Turkey.

From the book's last paragraphs, which summarises its theme -

"The Roman Empire of the East was founded by Constantine the Great on Monday, 11 May 330; it came to an end on Tuesday, 29 May 1453. During those one thousand, one hundred and twentry-three years and eighteen days, eighty-eight men and women occupied the imperial throne. Of those eighty-eight, a few - Constantine himself, Justinian, Heraclius - possessed true greatness; a few were contemptible; the vast majority were brave, upright, God-fearing men who did their best, with greater or lesser degrees of success ..."

"One of the first and most brilliant of twentieth-century Philhellenes, Robert Byron, maintained that the greatness of Byzantium lay in what he described as 'the Triple Fusion': that of a Roman body, a Greek mind and an oriental, mystical soul ... The Byzantines were human like the rest of us ... What they do not deserve is the obscurity to which for centuries we have condemned them. Their follies were many, as were their sins; but much should surely be forgiven for the beauty they left behind them and the heroism with which they and their last brave Emperor met their end, in one of those glorious epics of world history that has passed into legend and is remembered with equal pride by victors and vanquished alike."

"That is why five and a half centuries later, throughout the Greek world, Tuesday is still believed to be the unluckiest day of the week; why the Turkish flag still depicts not a crescent but a waning moon, reminding us that the moon was in its last quarter when Constantinople finally fell; and why, excepting only the Great Church of St. Sophia itself, it is the Land Walls - broken, battered, but still marching from sea to sea - that stand as the city's grandest and most tragic monument."

Justinian and his Empress Theodora were probably the model for Guy Gavriel Kay's richly colourful Emperor Valerius and Empress Alixana, in his excellent re-creation of fifth century Byzantium, "Sailing to Sarantium" (The Sarantine Mosaic - Parts 1 and 2).

Guy Gavriel Kay's books are usually found among the Fantasy and Science Fiction section, but he's miles ahead of William Gibson, in terms of readability, believeability and, most of all, ideas. My favourite of the lot remains the first Kay book that I've ever read, Tigana, which I found by chance in a second-hand book store (no, not Jean Tigana of France and Tigana-Platini-Giresse-Fernandez fame). Others that I believe will give people a good read include The Songs of Arbonne and The Lions of Al-Rassan.
