Software Spotlight: Hugin

The image above is a composite image, made from 40 photos I took this weekend. I stitched them together using the open source software, Hugin.

Hugin is a brilliant piece of software. I went and sat in a park and took 40 photos of my surroundings. I didn’t need any special equipment: no tripod or special lens, just my 7.1 megapixel camera which I bought quite a few years ago now.

In Hugin, I selected the photos which I wanted to combine into a panorama, and it automatically analysed them to try to fit them together. It did a pretty good job, but couldn’t work things out completely. It told me which sets of photos weren’t yet connected to other sets of photos, and let me create “control points” between photos–that is, points which I could identify as being the same in two different photos.

Once I’d given Hugin some extra control points and let it align the photos from that data, all I had to do was select the output settings and wait for Hugin to blend the photos together. I’m very pleased with the result! As you might imagine, I have a much higher quality version than the one above. I think I will make it into a poster.

Thinking and Dancing

The weather this weekend has been grand

The weather this weekend has been grand

It’s been a fun weekend. I do love sunny days, with a cool breeze.

Today I present you with some things to think about. Thanks to Melinda at &c. &c. for these most excellent links:

Also, I have been dancing at the Brisbane Lindy Exchange this weekend. Like last year, it has been a huge success! If you live in Brisbane, you should definitely consider coming along to some of the classes or social events run by Empire Swing.

Alice

I recently read Alice in Wonderland, which contains all kinds of linguistic fun. Let me share some of the bits that I enjoyed:

‘Mine is a long and sad tale!’ said the Mouse, turning to Alice and sighing.

‘It IS a long tail, certainly,’ said Alice, looking down with wonder at the Mouse’s tail; ‘but why do you call it sad?’

From chapter 7:

‘Do you mean that you think you can find out the answer to it?’ said the March Hare.

‘Exactly so,’ said Alice.

‘Then you should say what you mean,’ the March Hare went on.

‘I do,’ Alice hastily replied; ‘at least—at least I mean what I say—that’s the same thing, you know.’

‘Not the same thing a bit!’ said the Hatter. ‘You might just as well say that “I see what I eat” is the same thing as “I eat what I see”!’

‘You might just as well say,’ added the March Hare, ‘that “I like what I get” is the same thing as “I get what I like”!’

‘You might just as well say,’ added the Dormouse, who seemed to be talking in his sleep, ‘that “I breathe when I sleep” is the same thing as “I sleep when I breathe”!’

‘It IS the same thing with you,’ said the Hatter, and here the conversation dropped, and the party sat silent for a minute…

And another, this time from chapter 9:

‘Oh, I know!’ exclaimed Alice, who had not attended to this last remark, ‘it’s a vegetable. It doesn’t look like one, but it is.’

‘I quite agree with you,’ said the Duchess; ‘and the moral of that is—“Be what you would seem to be”—or if you’d like to put it more simply—“Never imagine yourself not to be otherwise than what it might appear to others that what you were or might have been was not otherwise than what you had been would have appeared to them to be otherwise.”’

‘I think I should understand that better,’ Alice said very politely, ‘if I had it written down: but I can’t quite follow it as you say it.’

‘That’s nothing to what I could say if I chose,’ the Duchess replied, in a pleased tone.

‘Pray don’t trouble yourself to say it any longer than that,’ said Alice.

‘Oh, don’t talk about trouble!’ said the Duchess. ‘I make you a present of everything I’ve said as yet.’

And lastly, also from chapter 9:

‘And how many hours a day did you do lessons?’ said Alice, in a hurry to change the subject.

‘Ten hours the first day,’ said the Mock Turtle: ‘nine the next, and so on.’

‘What a curious plan!’ exclaimed Alice.

‘That’s the reason they’re called lessons,’ the Gryphon remarked: ‘because they lessen from day to day.’

That was quite a new idea to Alice, and she thought it over a little before she made her next remark. ‘Then the eleventh day must have been a holiday?’

‘Of course it was,’ said the Mock Turtle.

‘And how did you manage on the twelfth?’ Alice went on eagerly.

‘That’s enough about lessons,’ the Gryphon interrupted in a very decided tone: ‘tell her something about the games now.’

Android Hardware Dvorak

I wanted to be able to type in Dvorak with the hardware keyboard of my ASUS SL-101 eeePad Slider. This involved gaining root access to my device.

I was surprised at how difficult it was to find clear instructions about gaining root access to my device. As it turns out, the process is the same as for the eeePad Transformer, which uses the same firmware. I first had to revert it to an older firmware (in the newer firmware, ASUS has patched the vulnerability). After that the process was quite straightforward.

Following these instructions to replace the keyboard layout with a Dvorak one didn’t seem to work, until I read this page, which explained that on this device Android only respects the keyboard layout file when the “ASUS keyboard” option is selected as the input method. This is somewhat annoying; it means I have to choose between ASUS keyboard which has a QWERTY soft keyboard and now lets me type Dvorak on the hardware keyboard, and AnySoft Keyboard which has software Dvorak, but results in QWERTY on the hardware keyboard. I’m sure there’s a way around this, but I haven’t yet spent the time figuring it out. For now I’m happy to have hardware Dvorak working at all.

Also useful: remounting the file system as read/write.

The Real Panic

My sisters discovered that once you defeat all the monsters in Castle Panic, you have time to build a real castle.
