Collective Knowledge

Dad asked me today who my teachers were at Pukepoto Primary School, which I could partially answer, with help (I think: Mrs Travers in J1 and J2, Mr Jones in Standard 1, Mrs Bellingham in Standard 2, and Mr Wilkins in Standard 3 and 4, and apparently someone else as a new-entrant).

This is an example of knowledge that Google simply can’t give you, of course.  Except now it can – or at least will be able to when this page is indexed.  When I remember, I’ll try this query again (161 hits at the moment, none of them with the required information, although in eight of the pages the “Tony Meyer” is me) and see if it works.

We wondered if Wikipedia would have an entry for Pukepoto School, and while it doesn’t, there is a mention in the entry on Pukepoto (a stub – if I had more knowledge I’d expand it, but I don’t really know what substance I could add).

New look

Since I’m updating the badtomatoes.org look at the moment (it should appear in a few days), I figured I might as well do this one too.  Since I’m still using the wordpress.com hosting my choices are much more limited here (and I don’t really want to put in a lot of effort editing the theme either), but I quite like this look.  If I ever get around to moving this site to a proper WordPress install on tangomu.com then I’ll probably change it again.

For some reason, badtomatoes.org is going from a fairly dark black and white theme to something quite colourful, and this site has gone from a light somewhat colourful theme to a dark black and white theme.  I’m not sure what that signifies!

Massey University: out of touch with the real world

A policy on passwords like the one that Massey University has is worse than no policy at all.  Of course, when I was there, they forced students to have a four-digit number as their password, despite the fact that doing so violated their own policy, so I guess it’s expected that this will be ignored. Particularly bad parts: passwords should

Contain both upper and lower case characters [and] at least one digit and one punctuation character. 

Case sensitivity is a worthy goal, and it does increase the complexity of passwords considerably.  However, it’s also the easiest pitfall for inexperienced users, which the University is full of.  Requiring both a digit and a punctuation character is completely overboard.

Passwords must be changed from their initial default value the first time a new user logs in, and at least every six months thereafter.  

I understand why institutions require this, but I don’t agree with the reasoning.  In practice, what happens is that people rotate between passwords, or if that isn’t possible, they rotate between variants of the same password, which adds very little in security).

Passwords, or even the format of passwords, should not be shared with anyone 

Passwords, sure.  But the format!  I can’t recommend how someone might come up with a good password (as the policy itself does)?!?

The “Remember Password” feature of applications (e.g. Outlook) should not be used. 

Just plain stupid.  There are so many reasons this is stupid that it’s not even worth going into them.To be fair, Massey University undoubtably isn’t the only place (probably not even the only New Zealand university) to have a policy written by people completely out of touch with the real world, but that doesn’t make it any less embarrassing to be an alumnus.

You catch more flies…

Following up on the honeypot successes, I’ve had two more since August. One in early October, and one a couple of days ago, both with the original domain (a .gen.nz) I used to donate.

I had wondered if perhaps the more rapid success for the later donations (.org and .com) meant that spammers were more likely to use the .org/.com addresses, but perhaps that isn’t the case (or perhaps it isn’t now).

You should still donate a MX entry if you can.

Delicious Library queries via SMS

A few months ago, I finally got around to cataloging all my books using Delicious Library. There were a few reasons for doing this – my insurance company wants a list of all the books in order to insure them for new-replacement value (rather than the few cents they probably consider they are worth), if anything did happen to them, I want to be able to print out a list and give it to a bookstore with an insurance cheque an wait for all the boxes to arrive, and, perhaps most importantly, it’s becoming difficult to purchase new books because I have to remember whether I’ve already got the book (or have just read it, or have just heard of it). It’s also just about impossible for anyone else to buy me a book (my favourite gift), because I might already have it (unless it’s on my Amazon wish-list, which I keep fairly up-to-date). I guess it’s also nice to keep track of books I’ve lent out, but that isn’t so common that I need software for it.

Just putting the books in the Delicious database covers most of these, apart from the issue of avoiding purchasing duplicates. Delicious Library can sync to an iPod (I don’t have one, but my wife does, so with a bit of work copying the library across accounts, that can be done), so that somewhat solves the issue of buying duplicates myself. It’s not perfect, though – for a start, I need to ensure that I have the iPod with me (easy to do for planned purchases, but not impulse buys). In addition, it seems that only 1000 books were sync’d – I’m not sure if the iPod is limited in the length of “notes” it can display, or if Delicious Library is limited in the number of books it can sync, or if something just went wrong in the process. This doesn’t at all help anyone else, of course, unless I give them a list.

Putting the list online is possible, through third-party utilities, but the one that I found that worked resulted in a page with so many images it would take forever to load, and while I put a custom-made version online that would load more quickly, printing the list out and taking it with you, or waiting until you could look at it online, isn’t particularly practical.

What I needed was a way to query the list using something that I and others would always have on hand. That’s really only a cellphone, either via voice (complex) or SMS (simple). ipipi, which I used in the past to send SMS messages from a computer, allows me to receive email from an SMS, which I could use to trigger an Applescript. While I could probably have done the whole job in Applescript, writing the search in Python was much simpler. Continue reading “Delicious Library queries via SMS”
