Apple’s iBooks Author, Interactive Textbooks, and All That Jazz

Below is an article that I wrote for MacTalk a few weeks ago. Thought I’d post it up here for posterity. Published without pictures unlike the MacTalk version.

Alternatively, Apple’s latest foray into the big bad world of education (and why it matters).

I’ve now had the whole weekend to think about what Apple’s education event means. Somewhere between the new Star Wars MMO, some epic rounds of Battlefield 3, and something that I’m calling “general internet procrastination”, I’ve thought about the implications for the education sector that this event has wrought.

As a quick recap, Apple released iBooks Author for the Mac alongside a plan to shake up the textbook industry as we know it (also featuring the iPad, iTunes U, and a few big-name publishers). There are those that think Apple don’t care about pros anymore, but Apple’s education event held in New York was proof enough that (and perhaps now more than ever), Apple cares about education.

What happens when you can’t see the forest for the trees?
Before we get into the meat of what all this really means for the future of education as we know it, I’d like to dispel a few misconceptions about iBooks Author that seem to have cropped up.

Firstly, there’s a few people getting caught up in the iBooks Author EULA, and how it apparently (depending on your preferred interpretation) dictates, totalitarian-style, what you can and cannot do with the app. Specifically, people have their underpants in a twist over the fact that books created using iBooks Author can only be sold via Apple; the question is, is that actually so unreasonable? Some say the whole situation draws certain parallels to the similar iOS/Mac app and Xcode equivalent, but others still say that’s different because Xcode doesn’t attempt to dictate what you can and cannot do with output from that app — iBooks Author, on the other hand, does. If we’re being really pedantic, there are even those that liken the iBooks Author EULA terms to what would happen if Adobe said you could only use files originating from Photoshop in a certain way. Those people are pretty far off the mark.

Let’s get one thing clear: Apple isn’t taking your copyright away.

Your content that you put into the app is still your content, you still retain full copyright of whatever material you put into an iBook, and pigs still don’t fly. Frankly, I think the whole “iBooks Author is telling me what I can and can’t do with files I produce using the app” is just a cry from those who are overly concerned about proprietary software and certain usage scenarios. Yes, Apple should probably open up iBooks Author (and iBooks themselves) to an iOS-like enterprise implementation, where books can be distributed internally in a company without having first been published to a public iBookstore. For the moment though, selling your iBooks through the iBookstore just means that you’ll get many more eyeballs on your content than if try to hawk it yourself. It’s also important to note at this point in time that you’re still very much permitted to give your work away for free — Apple aren’t preventing you from sticking your iBooks Author-produced iBook up on your website somewhere and letting it people download it for free. No, I guess the message from Apple here is that iBooks created using iBooks Author are much like iOS apps you create using Xcode: feel free to do other things with your iBook, but if you want to sell it, your best chance of success lies in the iBookstore.

Photography

My latest obsession is with photography. I’m hoping it’ll stick around for a long while yet, since I’ve always wanted a decent camera since as long as I can remember.

December of last year I acquired my very first DSLR, a Canon 60D. It was a sort-of Christmas present to myself (my parents and sister contributed), and I’ve been thrilled with it ever since.

I’m still very much an amateur, but I’m getting into photography in a big way. I’ve discovered the joys of street (photography), done numerous candid and portrait shots alike, and have learnt a huge amount from friends and whatever research I’ve managed to do on my own. I’ve done long-exposure fireworks photography with a friend, learnt a whole heap from the DigitalRev YouTube channel, and now even have a tripod to call my very own.

I had the semi-unique chance to shoot the wedding reception of a good friend I went to high school with the other day, and after realising I had a little more to say about it than would fit in 140 characters, I thought I’d write a little about it. That is, correct me if I’m wrong, what a blog is all about, right?

It just so happened a new lens I ordered arrived the day before the reception, a Sigma 30 f1.4. While I love my 50 1.8, it’s mostly too long for “fun” (read: random street photography and/or portraits) on a crop body — a 30mm focal length on a 1.6x crop body is much closer to the full-frame 50 equivalent, and an aperture of 1.4 is also pretty great (razor thin DOF at those kinds of apertures means your autofocus has to be perfect though, otherwise you end up with stuff that’s out of focus. Manual focus? Don’t even think about it).

The new lens arrived, and I wanted to do little more portraits with it — the reception was the perfect opportunity. A few short text messages to the groom later, and I was allowed to bring along my camera. In my mind I was the unofficial second shooter, but it didn’t quite turn out that way (more on this later).

It was the day of the big scary wedding reception, and after buying a suit in the morning, I finished work for the day and made my way to the reception. It turned out I was a few hours early, which wasn’t too bad as I got to scout out the location beforehand. I was worried about the light, and rightly so — the lighting in the reception venue turned out to be pretty terrible. Thankfully, earlier that day I had arranged for a friend to bring along his 580 EX II Speedlite. It was all pretty lucky actually, had I not had the Speedlite my photos would have been much, much worse — I doubt I would have come away with more than a handful of usable shots. As it turned out, I made excellent use of the bounce card and bounced the flash off the roof to great effect (after getting a few . It worked really, really well, and for a first timer I’m pretty pleased with how some of the shots turned out.

My original intention as second shooter was to cover the “lighter” stuff, stuff that the first guy wouldn’t have taken photos of as he was presumably focused on the bride and groom — but as we all know, expectations are far from reality. Turns out the first shooter is pretty worn out from a whole day of shooting the wedding (before, during the ceremony, and in the park after), so I get upgraded to official first photographer. The big leagues and all that. Pressure? I eat pressure for breakfast.

Roughly 750 RAWs later, and it was all over. Now that I’ve had a chance to look at the photos, I’ve got a few conclusions…

  1. White balance matters. I’m not 100% on this one, actually — some of the shots I took had a yellowish (but natural) tone to them, others had a much cooler (whitish-blue) tone. I thought some of the natural-looking shots would have been okay, but apparently not. Thankfully nothing that Lightroom couldn’t fix. Lesson learned.
  2. I thought the guy doing the wedding would have been more, uh, into the whole photography thing. A bit more organised, maybe. Turns out it was all pretty relaxed and casual, which was fine by me — I know some people  can be very particular about their photography , but this guy was pretty casual which was cool. I mean, I don’t think the bride and groom told him I was going to be the second shooter until everyone was actually at the reception…
  3. Post-processing in general kind of sucks. Flame me all you want, but I now have a heap more respect for the wizards who do crazy things in Photoshop to make photos look amazing — they’re pretty great. It’s just that the time required on an individual image is insane; maybe it’s because I’m just starting off and have no real idea about what I’m doing, but man, post kinda sucks. Thankfully, I didn’t do much post and certainly nothing that involved big ol’ Photoshop— I bumped up the exposure by a third, two thirds of a stop here and there, tweaked the brightness and levels a bit, and that was about it, really.
  4. I feel I’m at that point where I kind of have to think about the shot in order to take better photos. I mean, anyone can do the half-press, full-press of the shutter while composing photos using the rule of thirds etc, but I mean, I ended up with roughly 130 or so “usable” photos out of the 750+ I took. Sure, there were quite a few duplicate/triplicates of the same group or same person, but still, that’s a terribly bad ratio whichever way you cut it. Lots of the photos were out of focus, blurry, or the composition was fine but the wrong thing was in focus, etc. I guess it’s something I’ll have to work on, especially when dealing with dynamic subjects. The one good thing about landscapes is that they don’t move.

Most of all, I figured that I just enjoy taking photos of people, both posed and random candids. Which is kind of weird, because I’m not really the type — I doubt I’d be into, like, gig photography or anything like that, but doing photos of people at the wedding reception was actually pretty fun. Must be something about people smiling, or just me being behind the camera. It’s not so much as “capturing the moment” as it is about just having fun, and photography is very fun — I remember this one time I had set up a few younger couples for a group shot at the reception, and taking the shot only to have the flash not fire. Turns out I had turned it off for a few shots earlier, and promptly forgotten to turn it back on again for portraits — a exclamation of surprise and a hurried apology later, I flicked the switch on the flash back on and took another shot. Natural smiles all round, and it made for an excellent photo.

Yeah, more of that, please.

I’m still not sure where I’m going with photography. I enjoy it a lot, like, a lot a lot, but I don’t think I’ll be going pro anytime soon. It’s certainly something I’d consider, but there are certain aspects of photography which just freak me out entirely (I think most of it stems from being a little insecure about my “work” — it’s the whole process of delivering a final product to clients that freaks me out, including spending an hour in Photoshop slaving over a single photo when you’ve got hundreds to edit, and so on).

I’m not sure. I like photography, don’t get me wrong, and I’m more than happy to upload my best shots online, but actually doing something real? Just leave me to look at my photos in peace!

NYE 2011 Fireworks

I got a real camera for Christmas, a Canon DSLR, and the perfect time to take it out was the fireworks spectacular on New Year’s Eve for some tripod-assisted long-exposure photography.

Of course, I don’t actually have a tripod yet, so I had to go with a friend who was also interested in doing a similar thing. I borrowed one of his tripods, and off we went…

First we had to actually find a spot. Nutgrove Beach seemed like a good candidate, but it turned out it might have been a little too far away.

Admittedly, the above photo was taken at a focal length of 18mm (28.8 35mm equiv), but even at 135mm (216) I think it would have still been sub-par. You might have gotten Wrest Point in the shot, though.

We relocated to somewhere a little closer to Wrest Point, just on Sandy Bay Road.

I’m not sure that would have been any better. Slightly, but still not all that great.

Gratuitous iPhone shot of the “family” fireworks from basically the Wrest Point carpark entrance. Not bad, but even better when done on a DSLR:

After that we had about a few hours until the actual fireworks started, so we decided to play around with some more long exposure photography.

And then I did some shots I’ve always wanted to do… (They’ve been done to death, yeah, but I hadn’t shot them before.)

We looked at a few other places, but ultimately ended up across the river for the main event.

Blue dot is us, purple pin is where they launched the fireworks from (or thereabouts). We were right on the edge of the water, so a little closer than what the blue dot actually says we were…

10 second exposure at 69mm at f/5.6. No post, because I’m not exactly the type (and haven’t quite figured out how yet).

Inconsistent Application

Alternate title: The End

Well, ladies and gents, it’s been a good ride. Through thick and thin, you’ve successfully managed to ignore the vast majority of my posts on here, so I guess this is it. I am, of course, referring to the imminent demise of the Facebook Notes importer that works via RSS. If you’re reading this on Facebook, then this is probably the last post you’ll see from me for a long, long time — but if you’re reading this on my, you know, actual blog (www.bennylingbling.com for those playing at home), then you’re guaranteed the same sporadic posts that you’ve always had, with a money back guarantee! Okay, maybe not that last part. But still, random sporadic posts should be good enough for anyone, right?

What follows is a post that has had to be written for a while now…

Primary School

The year is 2001, and the Benny Ling you know is just 10 years old and in Year 5. He’s sitting in class, when suddenly, the teacher plonks down the marked copy of a previous maths test. He looks down, incredulous, at that red lettering: 100%. The perfect score.

I remember it like it was ten years ago. Sitting in class, when my teacher at the time hands back that maths test. It was on the decimal system, as I recall, fractions and that sort of stuff, and I managed to get 100% on it. The teacher exclaimed to the whole class that she had checked it thoroughly, twice, and that I had actually gotten 100% on a maths test. One of my favourite memories, and yet, my report for that year reads something like so:

“He is a very capable in all aspects of language and test results confirm this, yet work is sometimes presented at a standard below his best.”

“Benny’s work on his German project was most disappointing, far below the standard of which he is capable.”

I still have that maths test, somewhere.

Year 6 is perhaps even more eye opening, at least in terms of reports:

“In SOSE, which requires him to do research and put in considerable effort for a good result, he does not achieve as well as in other areas.”

And perhaps the most scathing comment of all:

“He is a very capable student, but often only does the minimum necessary, and homework is frequently not completed or of a standard well below his capabilities.” … “He is able to write for specific purposes but often does as little as possible.”

I was one of those students that always strived to finish first. One of those students that strived to be the best — but only at things I knew I could actually be the best at.

Secondary School

Fast forward a few years. The year is now 2004, and the Benny Ling you know is now a few years older, and perhaps even a few years wiser. He gets his Year 8 interim report, and that’s when it all starts to fall apart…

Citizens, I need firepower!

You’ve seen Mulan, right? That one scene where Mushu dons a scary costume, jumps into a fireworks box, and asks the attendants for some serious firepower?

One of my many (varied) vices is that I’m a bit of a Nerf enthusiast. Only a little bit, mind you, but that’s enough.

I now own the vast majority of dart-firing Nerf N-Strike toy guns, and I can count the models of same that I don’t own on one hand. I’ve imported Nerf toy guns from the US (thanks Amazon!) to get them just that little bit earlier, and when I saw that Nerf had introduced some new, disc-firing weapons (the Vortex series), my curiosity was piqued.

That being that, and having just started holidays, I decided to acquire some of these disc-based toy guns. My usual source (Target) didn’t have any of the new disc-firing Vortex series, much to my disappointment, so I decided to venture out to Toyworld.

Bear in mind the last time I went out to Toyworld was easily 10+ years ago, back when I was a young ‘un. My church was not too far from there, and sometimes, after the service on Sundays, a friend and I would venture down and explore the sheer excitement that was the huge, massive assortment of toys.

I went back to Toyworld today, and it was like nothing had changed. Every wall was packed full of toys. LEGO. Assorted water and sporting goods. Model cars. Model trains. Toys for girls, toys for boys — and most of all, Nerf toys.

I picked up all three Nerf toys Ben Kuchera recommended in his piece for Ars: the Vortex Praxis, the Vortex Vigilon, and the Vortex Proton. I might have even picked up the full-auto Nitron, but Toyworld didn’t have stock. That particular model will just have to wait.

Vortex Praxis: love the shotgun action. Pump-action handle better and more comfortable than the similar style on the N-Stike Alpha Trooper, and the 10-disc clip ejects like the magazine of a real assault rifle. Totally my style, and very fun to use. Only downside is the slightly non-too-sturdy stock — two thin arms are all that support the buttstock.

Vortex Vigilon: five round, with the same cocking action as the N-Strike Maverick. Instead of a rotating barrel, the Vigilon has a sort of “chamber” where you slot discs in. It’s not bad, but I probably wouldn’t trade my modded Maverick for it.

Vortex Proton: single shot, single disc. I absolutely adore the loading mechanism on this: pull the tab, slot a disc into the slot that appears, then hit one of the “slide return levers”, which retracts the tab you pulled out, and readies the gun for firing, all with a satisfying noise and action. Yeah, it’s only single shot, but it’s really, really cool to use. Plus, it’s the most compact of the new Vortex series — perfect for execution-style killings.

Range on all three disc-firing Vortex blasters was much improved over their dart-based cousins. Where the darts have pretty severe “bullet drop”, the discs kind of “catch” the air. The downside of their epic range (roughly 1.5x that of my best N-Strike blaster, the Maverick) is that because the discs are spinning, their accuracy isn’t as great as the darts (and they don’t whistle, or glow in the dark, or stick to things). You could probably expect to (accurately) hit a human-sized target about 12, perhaps even up to 15 meters away, but then again, a dart could do that kind of distance as well.

My only other gripe with the new Vortex series is that they’re pretty darn bulky. I’m not quite sure if it’s a mechanism thing for the discs, or whether Hasbro are just going for a new style, but seriously, although some of the space in front of the trigger is where the discs are loaded, pretty much everything below the Vigilon text is empty. There’s no way the Vigilon needs all of the bulk in front of the trigger, and neither does the Proton. The width I get — the discs are about 5-6cm in diameter — but otherwise, I’m pretty sure all that bulk could be cut down a little.

Overall, these new disc-based Vortex blasters aren’t bad.

Now I have to hunt down some of those clip-based water pistols… but that’s for another time. 😉

HP TouchPad, Part Two: Hardware

Let’s be honest here: as many have said time and time again, there is no tablet market, only an iPad one. For reasons unbeknownst to myself, I (still) don’t own an iPad. It’s not that I don’t want one, it’s that an iPad is a pretty sizeable outlay1 for a product that has an unknown usage ratio. Irrespective of the reason I don’t (yet) own an iPad, I do own just one tablet; the HP TouchPad.

After what can only be described as a particularly enthralling acquisition saga, it was time to delve into the TouchPad itself, and — perhaps more importantly — its operating system, webOS.

The TouchPad is a pretty basic tablet, really. No fancy bells or whistles here. It looks almost exactly like the original iPad does, only with a few more curves at the edges instead of the bevelled edge of the iPad 1, and with a few side ornaments re-arranged.

If you’re holding it in the correct portrait orientation (home button on the bottom of the face of the device), the speakers are on the left hand side. Yeah, speakers, as in plural: the TouchPad features two speakers with Beats(TM) audio. I’m not entirely sure whether the Beats(TM) audio is a hardware thing or a software one — perhaps even a combination of both — although my suspicion leans towards the latter, due to the presence of a toggle in Sound preferences to turn Beats(TM) audio on or off. In any case, the resultant audio emanating from those tiny but stereo speakers is pleasant enough, even above-average. Like all small speakers, they lack only in any real bass; more than capable of getting the job done, certainly, but no aural pleasure device. I wouldn’t go so far as I call the sound quality of the TouchPad “tinny”, but it’s definitely nothing to write home about.

The rest of the TouchPad is pretty standard: there’s a sleep/wake switch on the top right just like the iPad, and a 3.5mm headphone jack on the top left, also just like the iPad. On the right side (when held in the correct portrait position as before), there’s even a volume rocker, just like the iPad. Notably absent from the TouchPad is a physical silent switch.

What’s interesting is that the side with the volume rocker has an equal-spaced slot on the bottom part of the device. Pushing the slot in pops out some little sliding tray — presumably this is the SIM card tray for the mythical 4G version of the TouchPad that never saw the light of day (officially, anyway).

Moving on to the front of the device: up the top you’ve got a truly mediocre front-facing camera (that, somewhat surprisingly, ranks in at 1.3 on the megapixel scale), something Apple didn’t think about putting in the iPad until the second version. A peanut-sized “home” button (which actually glows when you’ve got new notifications on the device, acting as a notification LED — something no iOS device has) and a 9.7-inch, 1024×768 resolution LED-backlit IPS display (pretty much identical to the display on the first iPad) round out the front of the most discontinued tablet with the shortest availability period by the company with more misdirection than not you’ve never seen.
