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?

Screen Shot 2013-11-16 at 08.37.45

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:

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!

1984 – 30 years on?

I’m not very good at keeping up with politics and current affairs in general at present, and one treat I always allow myself on holiday is the shedding of even the limited news-reading and Today-programme-listening that I normally do.

And so the Snowden affair, which started while I was away, largely passed me by: when I got back they were discussing intricacies of conspiracy theories and extradition orders and it was a bit like trying to pick up a TV mini-series by starting on the third or fourth episode. I’ll save learning about it for when the movie version comes out.

But I did think John Lanchester’s article in yesterday’s Guardian was a pretty sane discussion of the issues, even for those of us who missed the opening chapters.

Nice extract:

I call this the “knowing you’re gay” test. Most of us know someone who has plucked up the courage to reveal their homosexuality, only to be cheerfully told by friends and family, “oh, we’ve known that for years”.

Now, though, search engines know facts about people’s thoughts and fantasies long before anyone else does. To put it crudely, Google doesn’t just know you’re gay before you tell your mum; it knows you’re gay before you do. And now GCHQ does too.

Flushing out the answer

Here at Status-Q headquarters, we’re having a new bathroom fitted, which means we’re getting all these newfangled gadgets that you youngsters just take for granted. Things like mixer taps, which our international friends are amused that we didn’t adopt about 50 years ago. I tell them that British plumbing is like the weather: it’s unpredictable, and we like it that way, because it gives us something to make polite conversation about when inspiration is otherwise lacking.

Anyway, we now have a cistern with one of these dashed clever dual-flush buttons. You know, with a small difficult-to-press button embedded in a large crescent. I think it’s a kind of Islamic yin/yang symbol. But the real mystery is that nobody seems to know quite how it works. It didn’t come with a manual, and even our plumber couldn’t answer some of my questions. Here are a few – perhaps the readers of Status-Q have greater lavatorial expertise than we do:

  • It appears from visual inspection that the small button provides a smaller flush than the big one (these things are difficult to measure, but that seems sensible). But what happens if you press both, which is the easiest thing for my chunky fingers? Are they additive in some way, producing a megaflush? Or is that the same as the big button alone?
  • If the authorities really want us to save water, shouldn’t the big easy-to-press button be the one that does the smaller flush, leaving you to add on the side button for the full monty?
  • In any of the above combinations, does a press-and-hold give you any more than a brief press?
  • Is there an international standard for flush-button-operation, or might all of the above vary by manufacturer?
  • How many unnecessary gallons of water are used around the world each day by people like me who, in the absence of such vital information, always press the biggest combination of buttons for the longest amount of time? Can Status-Q make a significant impact on world water consumption?

All enlightenment most welcome! Or failing that, I’ve at least given you something to ponder next time you’re sitting there…

A Brief History of Hawking

This is, I think, a lovely introduction to Stephen Hawking’s big ideas, in a two-minute animation commissioned by The Guardian.

The fact that it’s substantially the creation of my nephew Matt Kemp, who works at Scriberia, makes me like it even more! 🙂

Packing a punch

One thing I haven’t generally had to pack when going for walks in the countryside – until I went to Montana – is bear repellent.

20130904-211728320

These are standard issue in that part of the world – you can buy them everywhere.

To an Englishman, an aerosol seems more appropriate for dealing with a small insect than a charging grizzly, but since the usual alternative advice is to lie down and play dead in this situation (which may cause the grizzly to ignore you), I can see why these are popular travel accessories.
