TapWebsite graphs

3 Jun 2006 23:40 by Rick

This appeals to me as a form of immediate accidental art. Though not strictly web site graphs, actually web page, they are a derivative in graphical form of a structure created for another totally different purpose. Here is a graph of the home page of http://west-penwith.org.uk/ To understand it at the technical level you have to know that blue are links, red are tables components, green is the DIV tag, violet is for images, yellow are form elements, orange is for linebreaks and blockquotes, black is the HTML root node and grey is all the rest.

TapPlugins and extensions.

23 May 2006 11:22 by Rick

After enabling the Akismet plugin for WordPress the other day (which I will say now, is superb) I thought that I would investigate what others there were. I went to the WordPress Plugin DB and found over 1000. Having now read most of the one line descriptions I selected only one that I thought would be useful—Self Comment Notification Filter which stops you having to moderate your own comments. In the case of 99% of the others I still have absolutely no idea what they do or why I should want them.

And that, I think is the problem with the Plugin and Extension system; the same is true of Firefox and Thunderbird only worse because the users tend to be less technically minded. It is neat that the products are stripped down and functional with no excess baggage that you never use (unlike some other products we could name). But there is something missing from the mechanism for extensions. There is no quality control so you have to try them and see if they work; there is little version control so they may not be compatible with the next release of the base product if the author has lost interest; and there is no good advertising.

What seems to be needed is an organised reputation system, probably managed by the base product owners. To get onto the list you should have to provide a minimal of description, function, documentation and screen shots. You should need to commit to a period of support, and there should be an organised classification (to identify potential users) and rating system (to determine quality).

For WordPress the Plugin Database meets some of these requirements and for Firefox/Thunderbird the Firefox Addons site and the Mozdev extension room offer similar services, but they all lack that something that would encourage the general user to look for and find the useful tools.

Themes and skins suffer from a similar problem unless promoted by the base product owners—even with a product like WordPress, that is only likely to be used by the technically savvy, it is remarkable how many are set up using the default theme.

TapWhy Jabber?

21 May 2006 09:06 by Rick

I noticed that when I signed up for WordPress.com to get the required credentials for Akismet, one of the things you could put on your profile was a Jabber Id and it reminded me that the gospel is slowly spreading but needs a lot more impetus. This quote succinctly explains the situation which currently exists

I know a lot of friends who have Hotmail accounts. I also know a lot of friends who have GMail accounts. I personally don’t use either, I have my own email server at deepdarc.com. Do I need to have an account on Hotmail in order to email my friends who use Hotmail, or a GMail account to email my friends who use GMail? Of course not—that would be absurd. Yet, that is exactly the situation we tolerate with respect to Instant Messaging.

Read the rest of the excellent review of Jabber IM at deepdarc.

Afternote: When entering this post it wouldn’t let me put in an xmpp: protocol link—more work needed there I think. My Jabber ID is on my home page if you need to know.

TapArgggh, more comment spam

20 May 2006 19:43 by Rick

I got fed up with it—77 in the last week so I have installed Akismet. It was quite easy really.

But I was still curious how they were getting through, even though I require registration and signin before commenting. I found the answer is this forum message by Otto42. It seems they are not comments but trackbacks so a panic turning off comments won’t stop it as some people have tried. In fact turning off trackbacks won’t work either because each individual old post will still have them enabled. The recommended answer is Akismet—done that, so let’s hope it works.

TapWordPress upgrade

17:16 by Rick

Well that was dead simple. Those guys are really great, breaking it all down into five easy steps so it only took half an hour and that was deliberating each step carefully.

Now I really need to update the theme. I hacked the default one and I see that the upgrade made a few changes to that as well. This reveals a well known rule of programming—documentation only gets done on the first revision when you can’t remember how it works.

Unfortunately the upgrade hasn’t stopped the spam so phase two will be getting to grips with plugins.

TapComment Spam

19 May 2006 23:41 by Rick

In the last few days I have been hit by comment spam—rotten really as I don’t ordinarily get many comments at all. You won’t have seen them because there are two lines of defence. You first have to register an account and even then the comment is sent to me first for moderation. This probably puts legitimate comentators off but I see I was right in chosing this system.

The first of these bulwarks is not working. Somehow the spammers are getting comments into the system without first registering accounts. It seems to be a timely reminder that I need to upgrade to WordPress 2 so please excuse me if the blog is down for some of the time over the weekend.

A secondary benefit is that I am told that Akismet spam defence is built into the new version, so perhaps I may be able to relax the rules a bit, but one thing at a time.

TapGreen Geek ?

5 May 2006 12:15 by Rick

This week I did my bit for the environment; I unplugged my phone charger from the wall.

But seriously, how green are we techno-adicts. I did a quick audit of what is switched on and running when we are not even in the house.

  • Cable Modem
  • UPS
  • Router
  • Ethernet Switch
  • Wireless Access point
  • NAS controller
  • NAS drive
  • Print controller
  • Printer (in standby)

Each of these has it’s own Wall Wart. And in the domestic quarter…

  • 1/2 the HiFi amp (only the power amp half has an on/off switch)
  • FM Tuner (because it sounds better if kept warm)
  • Mini-disc recorder in standby (no power switch)
  • TV Digi box (would standby save anything here?)
  • VCR in standby
  • Various electric clocks
  • The fridge/freezer
  • Cordless phone system
  • Central heating controller
  • Doorbell transformer

It would be interesting to watch the meter to see exacly how much this lot consumes. It looks bad but we have made some effort; the router is a recycled PC so that has saved a chunk of landfill; we do switch the TV right off these days (mostly because we rarely watch it) Some other domestic stuff is chosen for its economy.

What more can we do?

TapTracking comments

24 Apr 2006 09:21 by Rick

I will quote another blogger (AR) here because it is an important insight. Unfortunately he is on an internal blog on our company system so not otherwise accessible

One of my main beefs with blogging, for like, oh, forever now is that there isn’t really a good way to track comments. When I post a comment on someone’s blog, I don’t want to have to repeatedly check that blog to see if anyone responded to my comment. Some blogs have evolved to support RSS feeds for all of the comments, or for the comments on a particular post. But I don’t like this idea either, mainly because I don’t want to have to manage a whole series of comment RSS feeds in my RSS reader.

An idea AR is experimenting with is to use a second instance of the Planet aggregator to collect all the comments to blogs on the Company Planet but this is not entirely satisfactory because it isolates the comments from their context (the original post) and also from other comments if the thread takes off with a life of its own.

Doing it the hard way, I have discovered the same thing. I subscribe to the comments feed of some of my favourite blogs but what I get is a random selection of remarks unrelated to their predecessors and the original context. This is not so bad in the early life of a post because you can usually remember what has gone recently before but getting a “me too, but such-and-such” to a post that is a week or more old is just meaningless static using this method. I also get comments to posts which had no interest for me in the first place.

IMHO a good start would be some sort of dynamic feed which generates entries to the comment stream of a post iff I have commented previously in the thread. Another approach I am thinking of is a method that automatically subscribes to the comment stream of an individual post as I make a comment. It would need to eliminate duplicates but also would need a configurable time-out so that old streams drop off either after a time lapse or perhaps if they go dormant for a period.

TapIgnored Standards

28 Mar 2006 10:21 by Rick

It is often hailed that Firefox and Opera are “Standards Compliant Browsers”; even Internet Explorer is not bad most of the time. It is a little known secret, however, that they are only compliant when it suits them (and us).

When it comes to handling “CSS floats”, that is sections of the content that push to the left or right of the window and allow the remainder to flow around them, what they do is work out the size of the content of the float and then position it according to instructions. If you don’t specify a width for the container then it is determined by the width of the content. This is what designers like as it allows them flexibility and a fluid layout.

However the Standard says

A floated box must have an explicit width (assigned via the ‘width’ property, or its intrinsic width in the case of replaced elements)

Only Internet Explorer on the Mac obeys this rule and creates havoc with some styling. Now this browser is dying out rapidly, it went out of development in Jun 2003 and out of support in Dec 2005, but it still lingers on, especially among genealogists it seems.

Yes, we can hack around it but that is not the issue. If we want the design that we are used to, then the standard needs to be changed, otherwise we tempt anarchy.

TapEmail dates

19 Mar 2006 17:26 by Rick

One of the oddities of Thunderbird, compared with other mail programs that I am used to, is that it time stamps the emails using the time they were (apparently) sent according to the clock on the sender’s system. This has some strange effects with mail from people with incorrect clocks, most noticable in spam. Whether it is because they are using hijacked systems to send the mail or it is some devious ploy I don’t know, but I have had mail in the last few weeks with dates from 1 Jan 1970 (just one) through 14 Mar 2000 up until 18 Mar 2007. The old ones go straight from the junk mail box to deleted, but the post-dated ones hang around at the front of the junk box for ages.
