Year: 2003

Each day webloggers across the world post news, comments and little fragments of personal information onto their sites. And everything that they post will be forever associated with that specific day in history. But they’re not the only sites to connect a piece of writing or a picture with a day. In fact all over the internet there are hundreds of ‘[something] of the day’ or ‘on this day’ sites – from “Astronomical Picture of the Day” through to “Dilbert Cartoon of the Day”. There’s a whole category on Yahoo dedicated to these things.

This hack allows you to put an automated link on the bottom of each of your posts to the Dilbert cartoon (or astronomical picture, word of the day etc.) that was published on that day. You can use it to add a little context to the events on your site or just to show off your interests.

First things first – what are we trying to link to? These sites often have simple URLs that are based upon the date on which they were initially displayed. For example the “Astronomy Picture of the Day” for February 23rd 2003 has the URL:

antwrp.gsfc.nasa.gov/apod/ap030209.html

…where the six numbers near the end are the year (03), the month (02) and the day (09). The Dilbert cartoon for the same day has this URL:

dilbert.com/comics/dilbert/archive/dilbert-20030209.html

…which uses almost exactly the same format except with a the year spelled out in full (2003).

So in order to insert these links on a day-by-day basis, we’re going to have to put the basic URL in place without the date elements, find some way of inserting those date elements and make sure that they’re formatted so they’ll work as a link. We’re going to do this by using some of Moveable Type’s most useful and versatile features – the <$MTEntryDate$> tag. If you insert this tag into your templates by itself it will use its default setting – which is designed for reading and will look a bit like this: “September 9, 2003 11:44 PM”. But you can easily override this by using the format attribute and one or more date-tag variables. Here are a couple of examples of how you might format <$MTEntryDate$> and what the result would look like on your published page:

<$MTEntryDate format="%d %b %y"$>
would look like "09 Sep 03"
<$MTEntryDate format="%Y: %B, %e"$>
would look like "2003: September, 9"

Here are what some of those letters mean:

Month:
%b - name abbreviated to three characters
eg. Sep
%B - name in full
eg. September
%m - presented as two digits padded with a 0 if necessary
eg. 09
Day:
%d - two digits padded with a 0 if necessary
eg. 09
%e - two digits padded with a space if necessary
eg. 9
Year:
%y - two digits padded with a 0 if necessary
eg. 01
%Y - four digits.
eg. 2001

So to make those daily URLs all we have to do is change the original URLs to include the <$MTEntryDate$> tag like so:

From:
http://antwrp.gsfc.nasa.gov/apod/ap030209.html
to:
http://antwrp.gsfc.nasa.gov/apod/ap<$MTEntryDate
format="%y%m%d"$>.html
From:
http://www.dilbert.com/comics/dilbert/archive/dilbert-
20030209.html
to:
http://www.dilbert.com/comics/dilbert/archive/dilbert-
<$MTEntryDate format="%Y%m%d"$>.html

So this is what you’d put into your template:

<a href="http://antwrp.gsfc.nasa.gov/apod/ap
<$MTEntryDate format="%y%m%d"$>.html">
Astronomical Picture of the Day</a>

The instruction manual for Movable Type contains detailed instructions about transferring your weblog from Blogger and Blogger Pro, and these instructions work extremely well if you have not been maintaining your site for very long. But while it’s rare for there to be a problem with the importing process, exporting weblogs from Blogger isn’t always so easy.

The normal transferral process is essentially three stages:

1. Replacing your Blogger template with one that formats your data in a way that Movable Type will understand.
2. Changing your Blogger settings to produce one very large file containing all your data.
3. Inserting that file into Movable Type’s import directory and pressing the import button.

Stage one is the simplest stage and presents no problems. You simply copy this text into your Blogger template page:

<Blogger>
AUTHOR: <$BlogItemAuthor$>
DATE: <$BlogItemDateTime$>
-----
BODY:
<$BlogItemBody$>
--------
</Blogger>

If you are using Blogger Pro, you should add the title tag to your template so that it reads like so:

<Blogger>
TITLE: <PostSubject><$BlogItemSubject$></PostSubject>
AUTHOR: <$BlogItemAuthor$>
DATE: <$BlogItemDateTime$>
-----
BODY:
<$BlogItemBody$>
--------
</Blogger>

Click to save the template, and you’re done.

Stage two is a little trickier. Firstly you change your Blog Filename to something other than the name you normally use. This is just so that you don’t over-write your normal front-page while exporting. Then you set the Date/Time Format to the format MM/DD/YYYY HH:MM:SS AM|PM and turn off Convert Line Breaks.

There are two other things they tell you to do in the instructions and these are (in Archive Frequency) turn your archives off and then (in Formatting) set the ‘Show N days’ posts on main page’ to be higher than the number of days you have posted. At this point if you publish your blog, you’re supposed to get one massive file containing all your posts.

Unfortunately this often won’t work if you’ve been weblogging for a while. Firstly, you can’t put a number into ‘N day’s posts’ field that’s in excess of 999 days, which is a bit less than three years worth of posting. Secondly, even when it finally publishes the file, it is likely not to actually include even that three years of posts. In fact, you’re more likely to get around one year’s worth of exported content.

In fact the best way to import files into Movable Type turns out to be by renaming and republishing your ‘archive’ templates rather than your main template. If you transfer all of those over into the import directory instead of your main page, Movable Type doesn’t seem to have any trouble importing them all in one go, and Blogger has considerably less trouble generating the pages.

The only other thing to bear in mind is the number of Movable Type entries. Movable Type will number your entries in order of file name and then from the top of the page down. If you manage to export everything from Blogger in one go, then the layout means that the most recently created post will be given assigned the MT post number 1, with each subsequent post’s number increasing incrementally even as you go back in time. While your posts will always be displayed in date order, this post numbering can be confusing. You might wish to explore ways of reversing the order of the posts in your import file. This is particularly true when you’re importing from multiple archive templates, as it will start with the earliest dated file, and then with the oldest (first) within it – effectively completely messing up the order of you posts… Either way, good luck!

One of the neat features that comes with Blogger Pro is the ability to have your weblog posts e-mailed off somewhere when you publish them. And this presents opportunities to extend your tiny empire right off the web and into people’s inboxes. Why not set up a one-way e-mail list which people can sign up to instead of slogging over to your site each day? Or maybe you would like to start a full discussion list with new debates inspired by your daily fevered rantings!

In order to set something like this up, the first thing you need to do is find a free mailing-list site like Yahoogroups (http://www.yahoogroups.com). Set yourself up a basic list to start off with – and decide whether you want everyone to be able to join in with conversation on the list or not. The only thing you have to do is make sure that the e-mail address you (or you and your friends) use in your Blogger settings are signed up as members to the mailing list and are able to post new messages. When Blogger sends out an e-mail containing the text from your latest post, it will make it look as if it came from your e-mail address. So if that e-mail address is not a member of the mailing list, then it will just bounce right off and no one will get to read it.

The last thing you have to do is go to the settings page on Blogger under the e-mail tab and put the e-mail address of your mailing list in the Blogsend field. If you are using Yahoo then this will be formatted like so:

[name of group]@yahoogroups.com

And you’re done!

Just two more tips for turning your weblog into an effective mailing list. As soon as you click on publish, your post will be sent out to everyone on your list and can’t be taken back. So make sure to edit and revise your post carefully before you publish it – saving it as a ‘draft’ when you’re not working on it. And secondly think carefully about how many e-mails people like to receive in a day – if you’re a prolific poster, why not encourage people to receive all your posts in a ‘digest’ form once a day. That way they’ll never want to kill you with axes.
