DVD layer changes

What is it with DVD authoring that the production houses can’t put the layer changes somewhere sensible, like preferably between scenes where there’s no sound? Looking through Michaeldvd.com.au’s reviews, they note a variety of stupidly placed layer changes:

  • The Princess Bride — The layer change is at 49:58 – it is not a good layer change, because it interrupts the score, but it only lasts a moment. The R1 Special Edition has a far better layer change – it’s inside a silent black frame after Westley is knocked unconscious.
  • O Brother, Where Art Thou? — The pause is a little jarring and noticeable
  • Virus — This is during a natural fade to black, but it is still quite noticeable due to the interruption to the music.

With TV series on DVD, most authors do the sensible thing and put the layer change between the episodes. But sometimes, evidently from pure laziness, they just let it fall elsewhere.

  • The Office — For some reason, the layer change does not occur between Episodes 3 and 4 (as I would have expected) but about 3:57 into Episode 4 (Title 4, Chapter 1).
  • Some Mothers Do ‘Ave ‘Em volume 2 — This is an RSDL disc, and once again the DVD authors have inexplicably put the layer change within one of the episodes instead of between them.
  • Empires-Peter & Paul and the Christian Revolution — This disc is RSDL-formatted, with the layer change occurring at 2:30 in Episode II – a crazy and infuriating place to put it when it could have more easily and logically been placed in between the two episodes.

Given it’s a well-known drawback of dual layer DVDs, surely it’s not that hard to put the change somewhere where it won’t be noticed. Crap layer changes really destroy the atmosphere of a movie or TV show, and show up a big flaw in what otherwise is a very satisfying and popular domestic playback medium.

Stupid fat USB drive

What is it with USB keys and ports? I’m pretty sure there’s a standard about the physical dimensions, yet there are plenty of computers my Stupidly Fat 256Mb Lexar JumpDrive won’t plug into (I’m looking at you, Compaq/HP) due to lack of clearance. I have to tote a cable around with me to ensure it plugs in.

In other news, some guy’s made a Lego USB JumpDrive 256 MB… although why you’d do that is beyond me.

Browser vs Website

Am I the only person who uses Alt-D to get to the address bar in Firefox? I suppose I could also use Ctrl-L, or F6, but I’ve settled for Alt-D, probably because it can be easily done with one hand — my left hand — and is close to the bottom of the keyboard, making it easy to find.

Problem is some web sites implement access keys that conflict with this. The default setup for MediaWiki sites uses Alt-D as a shortcut for deleting pages! Thankfully it goes to an Are You Sure confirmation before actually doing it. They seem to have disabled it on Wikipedia, but others still have it.

Likewise, Horde (web mail) uses Alt-B to Blacklist mail senders, conflicting with Firefox’s Bookmarks menu.

Firefox doesn’t appear to have an about:config tweak for turning all such keys off, though altering accessibility.accesskeycausesactivation to False will merely put focus on the link with the access key, not “click” on it.

This article discusses access keys in detail, including listing the requirements for access keys on UK government sites. Alt-5 for FAQ… hmmm.

Binary Output

Last night Owen started experiencing the symptoms of his first cold, which prompts me to talk about communications with babies. Newborn babies have only one output mode: screaming. Communicating with the world is a somewhat limited experience when joy, fear and hunger are all exhibited using the same mode of operation. From observation, crying may mean:

  1. Please feed me.
  2. I need to burp.
  3. I’m cold.
  4. I’m tired, please put me to sleep.
  5. I wish my nappy to be changed.
  6. The { toy | valuable object | fragile object } that I can’t reach – give it to me. Now.
  7. No, not that one, the other one.
  8. I’m bored. Amuse me.
  9. Ow, that really hurts.
  10. Carry me / lift me up.
  11. Holy crap! Don’t let that happen again! Are you listening?

Often, context will allow distiction between these options. It’s like a computer system saying “Something went wrong.” I’ve seen computer systems, particularly embedded ones, behave in a similar way. Often through design. Like, if they give you one red / green LED, then you’ve got green – all is good, red – not so good. You might get away with blinking them, and maybe even combining them to form orange, but there’s only so far you can take that (“Hmm, 600ms blink rate – that must mean that ethernet port two has a receive failure – because a 650ms blink rate would mean RAM failure”). That BIOSes doing their Power On Self Test use the PC speaker to report error codes prior to the video system coming online, I think the maximum number of beeps you’d get out of that was eleven… better pay attention and count them out. And a lot of Common Object Model errors are along the lines of “COM didn’t work because something failed”.

Interestingly, often babies don’t care too much that you understand them. They’ll keep on with the output, secure in the knowledge that you’re doing everything you can to determine what it is that they’re trying to say. And servicing one system fault may merely unmask another – a wet nappy may be followed by the need for a feed.

Screeching may also mean:

  1. This is great fun.
  2. Ha! You found me!
  3. Look at that guy, he’s funny.
  4. Hello, toy. You’re red.

The point being, the obviously inferior nature of binary output means it’s replaced as soon as possible by something else. Talking, outputing to screen, COM+, whatever. Oh, except COM+.

Cathy and I want to increase the output vocabulary of our son by using Baby Sign Language, mainly as a way of avoiding the expected trantrums: apparently, kids can sign much earlier than they can talk – like, children of deaf parents are signing from six weeks of age. Most excellently, I got given a book on the subject for Christmas, and joy-of-joys it was Australian made, so rather than American Sign Language, it was filled with AUSLAN, meaning it will have some use as a language outside on family communication (6500 Aussies – my perceived use rate is higher, because I work on St Kilda Road – home of the Victorian College for the Deaf). I’m seeing some comprehension from him, but I’m yet to see him generate any signs. Having re-read the Wikipedia article on the subject, I’m going to try to sign with Cathy when he can see us. I’ll let you know how this little experiment turns out.

Maintenance nightmare

Unmaintainable Plumbing - kids, don\'t use silicon sealant to hold plumbing in place
Houses need maintenance, it’s just a fact of life. Things wear out. But programmers are not alone in creating artifacts without thought for the subsequent fixing of the going wrong of things.

Take a look at this tap. This tap is copper, as you can tell by the oxidation. Inside it is a washer that, as a function of how many times it’s been opened and closed, now needs replacing. This is normally a simple matter of turning off the water supply to the house, unscrewing the tap body, popping out the old washer and slipping in a new one. But if the plumber or whomever followed in their footsteps decided to make things more watertight by the liberal application of silicon sealant, you’re in for some fun times digging it all out so as to be able to get a spanner onto the bastard of a thing.

The plumbing all through my spacious bathroom continues in a similar vein.

One of the shower taps can’t be removed with a spanner because it’s too deeply recessed into the wall. So deeply recessed that the tap had to be extended out so that the cover could screw on. But rather than extend the tap out via a pipe extension, the tap was extended out with a thread extension. So, joy of joys, I can’t change the cold water washer.

Part of the house maintenance was to install a Residual Current Device, a saftey switch. This protection extends to the spa bath’s pump, which is how we found out the pump has a leakage problem – switch the pump on, and the whole house is plunged into darkness. Should be a simple matter of locating the pump, determining where the unit has degregated, and replacing it. If, say, it was externally mounted. Which it isn’t. I believe it’s mounted under our bathtub, in the cavity between the tub and the wall. There is no way to access this area, not via a removable panel or anything of the ilk – the whole lot has been tiled in. Which tile should I remove to get to the unit? The left hand side or the right? No one knows. Naturally, there are no spare tiles to replace any that get broken in the search. For all I know, the pump may be under the floorboards, but the bathroom’s just about as far as you can get from the underhouse access trapdoor, and I haven’t gotten up the courage to go looking for it yet. If the pump’s not under there, I hope there is under-floor wiring that will give a hint as to the location of the pump – but I’m not holding my breath.

What home maintenance nightmares have you seen as a function of poor design?

XP defrag

I’m not overly impressed with the Defrag utility in Windows XP. In my eternal quest to try and speed up my mysteriously slow work machine, I decided to give it a go. Cleaned up a bunch of files first, to give the C: drive 6.5Gb free (out of 29.3Gb). Analyze: said I should defrag. OK, so I left it running over night…

Came in the next morning. The little colour graph showing where files are didn’t look terribly different from how it was left. Still lots and lots of red (fragmented files). It said it couldn’t defrag some files… basically anything over 15Mb.

Defrag

Out of curiousity, I clicked Analyze again. “You should defrag this volume.” What, again? What’s the point?!

I did some more purging and eventually ended up with about 10Gb free. Tried it again. Better, but it still couldn’t/wouldn’t move anything bigger than about 30Mb. Weird.

At least the machine seems to have sped up a tad now.

iPod Shuffle not recognised

What do you do if the iPod Shuffle that your 8-year-old was given for his birthday doesn’t appear to iTunes, the iPod updater, or Windows?

You roam around the iPod support pages, trying out the suggestions: reset the iPod, reset the computer, download the latest software (almost 47Mb for the iPod updater, and another 35Mb for the iTunes update with the bundled Quicktime that you don’t actually want), try resetting the iPod service, remove the software then repair it again… etc, etc, etc.

Then you notice footnote 5 of the iPod Shuffle specifications, which says: Some computers require either the optional iPod shuffle Dock or a USB cable extender (sold separately).

Sure enough, for me, a USB cable extender did the trick.

You know, including that in the support pages wouldn’t hurt.

Acer’s web site needs work

I’ve set up my new desks at home, and have been looking around at good deals on LCD monitors. Officeworks have some Acer ones on special at the moment, so I went to look at the Acer web site to review their dead pixel policy.

It’s a mess in Firefox. Looks rather better in IE. But we’ll live with that for a moment.

Find the page with warranties, and try to look at their monitor warranty:

Error 404
Not found – file doesn’t exist or is read protected [even tried multi]

Great. Find their contact page. It insists on knowing what OS I’ve got installed, because it thinks it’s only for tech support contacts. I lie. Eventually get the form submitted with the info above. It submits, then takes me to… another 404 page.

Bzzt, strike 2. Hopefully the message got through.

So then I tried a site search for “dead pixels”.

Error 500
HTTP Web Server: Lotus Notes Exception – Database is not full-text indexed

Bzzt, strike 3. Acer really needs a revamp of its web site.

Portable applications

Here’s a handy thing: portable applications (that is, those that can live happily on a removable disk, without having to be installed to run properly), and portableapps.com is has them categorised and available for download. They include dev tools like NVU and FileZilla, all the way up to portable versions of OpenOffice.

Sony joins iTunes AU

If you haven’t totally banned purchases from Sony due to the rootkits, you can at least now buy Sony BMG music tracks via the iTunes store; they’ve backed-down on refusing to have their artists available there.

Meanwhile Apple is under fire for including a “phone home” feature that’s turned on by default in the latest version of iTunes (the Mac version only so far?).

Update Friday 7am: EFF: Apple backs down on the “phone home” feature.
