Cheating with Pebble

I’m pleased to say that I hadn’t thought of this particular use for my Pebble smartwatch!

A super response

We were talking at lunch today about the foolishness of that old interview question:

“What would you say is your biggest weakness?”

Several people proposed suitable responses, but my favourite came from Richard. His suggestion?

“Kryptonite”

The habits of Hobbits

My quick review of the new Hobbit film: I enjoyed it a lot, though perhaps not as much as the first one. Too much romance, not enough Mirkwood, too many echoes of LOTR, and somewhat excessive use of decapitation, but, it must be said, an exceedingly fine dragon.

Tolkien purists (like Rose) will be furious, but my view is that you have to change even a good book to make a good film. And, if you’re going to invent new characters, then you’ll get fewer complaints from me if you have them played by people like Evangeline Lilly.

The middle film of a trilogy is always the hardest to do, to which a fair response would be that they were foolish to do it as a trilogy. That, I imagine, was determined by pure economics. It’ll be interesting to see whether Peter Jackson can do something really new with part III. In the book, Bilbo misses the whole final battle through being knocked on the head. Somehow, I think the movie may deviate from the canon there…

Meanwhile, I imagine that the entrepreneurs of New Zealand’s South Island are already planning barrel riding trips for the spring tourists…

Being social…

Some people find these scribblings through Google, others through RSS, Tweets, Facebook or App.net posts. And you lovely readers often write comments, but in all these different places, so only a subset of other readers are likely to see them.

In an attempt to make it easier to post comments here on the site, I’ve now enabled one of these newfangled social login things, so you can post using your Facebook or Google account if preferred. Other options may come along in due course!

Just wondering…

What is it that estate agents really mean when they talk of a “deceptively spacious” property? It’s one of their favourite phrases, after all.

If I say that my wallet felt deceptively full before I left the house, doesn’t that suggest that later, at some inconvenient moment, I discovered I had less money than I thought? Still, perhaps the operative word there is felt, which implies that I was mistaken?

OK, then, so if a house actually is deceptively spacious, that must mean that it does have a lot of space, but for some reason that doesn’t bring with it the characteristics that you’d normally associate with spaciousness. It’s a very inconvenient shape, for example, so you can’t actually use it as you would expect.

Or there is occasionally some warping of the space-time continuum in that area, so that when you visit, it is spacious, but later on you’ll discover it’s only suitable for hobbits? As in, “it’s deceptively spacious at the moment”.

Yes, I guess that must be it. Good of them to warn you in advance.

Welcome To My Humble Adobe

adobe-logoAs many of you will know, two months ago, Adobe’s servers were hacked into and the user information stolen. At first this was thought to be a major breach, with about 3M records lost. Then the number went to abut ten times that. Now, however, there is talk of it heading for the Guinness Book of Records, as it appears the number may be closer to 150M!

Now, the passwords were encrypted (or, more technically, ‘hashed’), so the bad guys can’t just read them off. But they weren’t encrypted as well as they might be, in particular because if several people use the same password, the system stores the same thing. So if you know one person’s password, perhaps because you got it from a previous hacking incident elsewhere and can tie it to their email address, you can now work out anybody else who uses the same password.

But it’s more fun than that… and there’s a great article on the Sophos site going into more gory detail if you’re interested.

One column that wasn’t encrypted in the database was the one holding the ‘password hints’… you know, the phrases you can put in on some sites to remind you if you forget your password.

Now, the most popular password is “123456”, which encrypts to “110edf2294fb8bf4” in the Adobe database. Hundreds of thousands of people use this one. Another very popular one, believe it or not, is “password”, which becomes “2fca9b003de79778 e2a311ba09ab4707”. (You can see more of the most common choices here.)

If you know the encrypted form, you may not be able to work out the original. But if many thousands of people use it, and just one of them gives it away in the password hint, then things become trivial. And it turns out that there are lots of lovely examples in the Adobe file, where users have put in hints like “Rhymes with assword”, or ‘1-6’…

Anyway, if you’re curious about whether you appear in this list, which you might if, say, you’ve ever downloaded Acrobat, there’s a a very nice service that LastPass have put together at:

https://lastpass.com/adobe/

where you can type in your email address and it will let you know if you’re in the database. It can also email you a link showing how many other people used the same password as you, and what some of their hints were. Which can be quite sobering.

I’m embarrassed to say that mine, which was mildly obscure, I originally thought, had 40 other users. That’s only 40 in 150 million, but it’s still not good for precisely the above reasons. I’ve had an Adobe account for a very long time, and this password predated my use of 1Password to generate unique and complex passwords for each site. Thankfully, since I’ve been storing my passwords in 1Password for quite a long time, it’s easy now (if somewhat tedious) to find the other elderly accounts on which I’ve used it, and fix them…

How about you?

Time travel

As we know, people in the past were black and white – you can see that in the photos…

But there are some very dedicated artists who, using today’s technology, are doing a fabulous job of recolouring some iconic images from the past.

There’s a great selection here. I find them very compelling.

IMAP, Sent mail, Apple Mail and Mavericks

This is one of those posts that’s chiefly intended for those Googling for a particular problem. It might still make gripping reading, though, for those of you interested in the internals of email protocols…

Most email programs nowadays allow you to specify the folder in which you want to save your outgoing messages, and choose whether that should be stored locally or on your email server. (Assuming you’re using IMAP to fetch your mail, that is. If you’re still using POP, you should get another mail provider. And if you’re using Exchange… well, you have my sympathy…)

But different apps have traditionally had different names for this folder: some call it ‘Sent’, others ‘Sent Items’ or ‘Sent Messages’ and some will use a folder with one name and display it as something else to the user. (The same is sometimes true of ‘Drafts’, ‘Trash’, and ‘Junk Mail/Spam’). So, over the years, I’ve tended to standardise on ‘Sent’, and when I set up a new mail app or a new machine, I configure it to use that folder.

But recently, that setting didn’t always seem to be stick, and I found some of my mail would end up in different folders when sent from some devices. Still, I persevered, until I installed Mavericks on my Mac, and found that the setting wasn’t even available on Apple Mail, at least, not for my main account – it was greyed out! What could be going on?

So I started to investigate. I dug into the file that Mail uses to store information about its accounts (currently ~/Library/Mail/V2/MailData/Accounts.plist) and I came across a setting which gave me a clue: it was called HasServerDefinedSentMailbox, and for this account it was set to YES. Mmm…

In the past, IMAP basically just provided you with a smart filing system for your mail, and it’s proved a remarkably resilient one, when compared to other formats. As an aside, I felt very old recently when I told a colleague in the lab that I had used the same method for storing my mail for ages, and had emails from 1991/92 in there that were just as accessible now as they had been then. He laughed, and said, “That’s the year I was born!”. Sigh… Still, compare that to data stored n tapes and floppies.

Anyway, a few extra features have been added since then, and one of these came just a couple of years ago. RFC 6154 describes ‘new optional mailbox attributes that a server may include in IMAP LIST command responses, to identify special-use mailboxes to the client, easing configuration’. In other words, the server can tell your app which folders to use for these key functions. This makes a lot of sense, particularly when your email provider also has a webmail interface, for example. I use Fastmail, which has a really good one, and, of course, it needs to know what you want to use for sent mail, drafts, etc when you’re using it via the web. Fastmail reflect these folder choices in the IMAP protocol, to keep everything consistent. Which is fine by me: I now simply stick to using the ‘Sent Items’ folder that the server recommends, and all is well on all my devices.

Anyway, all of that is a long way of explaining why you may find the ‘Use this mailbox for’ menu items are greyed out, and why on iOS devices you may try changing the ‘Sent Mailbox’, only to find that your new setting doesn’t stick. If your server is specific about which folders should be used, Apple will take that setting seriously, which I think makes sense, but they aren’t yet very clear in the UI about why you can’t then change it yourself.

Hope that’s useful to somebody!

Time, the final frontier

Here’s a list of actors, who have something in common:

  • Charles Seel
  • Judith Anderson
  • Morgan Farley
  • Richard Hale
  • Anthony Jochim
  • Felix Locher
  • Celia Lovsky
  • Leonard Mudie
  • Abraham Sofaer
  • John Warburton
  • Ian Wolfe

What ties them together?

They all acted in Star Trek.

And they were all born in the 19th century.

I think that’s quite cool.

Reviewing peer review

Those of us with a firm belief in the scientific method need to read this Economist article about how easily it can fall short of its ideals.

The good news is that this is being brought to light… In fact, I would propose the term Metascience, if nobody has already coined it, to describe this kind of work: the application of the scientific method to the scientific method!

Atomkraft? Ja, bitte.

I’m sitting in a traffic jam behind a car bearing a sticker, “Atomkraft? Nein danke.” (Nuclear power? No thanks!)

I’ve always liked this design, which has been around for some time – the sun with the smiley face makes it into a nice, happy, positive statement. It’s a clever bit of marketing.

However, the sun is, of course, powered by… ?

How DO you make good coffee?

Seth Brown has been doing some experiments. There are still many unanswered questions, but it’s a more rigorous approach than most of us have ever tried!

Nicely done!
