There have been a few stories lately for investors rather than techies that have a few inaccuracies, probably because they’re written by finance/ business journalists rather than tech journalists. (Nothing wrong in that; I know my HTML5 from my CSS but couldn’t tell a gilt-edged bond from a derivative.)
Here a few notes for analysts and journalists that might chance upon this blog.
By 2016, more than 2.1 billion mobile devices will have HTML5 browsers, up from just 109 million in 2010.
Before the expansion from “just” 109 million to “more than” 2.1 billion makes you rush out and leverage your portfolio, we need to know what our anonymous author means by the term “HTML5 browser”.
If you define an “HTML5 browser” as one that supports all features of HTML5 then there are precisely zero in existence. (You’d need to define “HTML5″, of course, but that’s anotherstory.)
If you define an “HTML5 browser” as one that can consume some HTML5 features, then all browsers are “HTML5 compliant”.
Please, dear analyst/ journalist friend, define what you’re talking about before giving precise figures and talking about accelerating adoption. (I’m always up for being contacted – email bruce at this domain – if you need to check something out, by the way.)
Our anonymous author quotes a Mark Beccue saying “I believe that Apple will be the key driver of HTML5″. Mr Beccue is, of course, at liberty to believe what he wants. Until my nephew was three, he believed that there was a creature that lived in the toilet called The Poozilla (I’d like to apologise to him publicly here). Believing it doesn’t make it true.
There are many claims to be the “driver” of HTML5. Opera began it, of course; Ian Hickson edits the spec and works for Google so you could argue that Google is a driver. As you like, and whatever gets you a better headline.
The truth is that browser manufacturers are driving it collaboratively because if browsers don’t render HTML interoperably, developers will use some proprietary technology instead. (This doesn’t have to be a prosaic truth: the fact that all browsers are working together on HTM5, if not on other technology, is quite a story.)
Consumers benefit from interoperable webpages: most people use multiple devices and browsers; it’s stupid if you can use your bank website on your work machine, but not your Linux netbook or phone. There are significant advantages to HTML5 over HTML 4 for developers.
Mr Beccue (or the anonymous author channelling Mr Beccue, as we are denied any link to Mr Beccue’s full analysis) believes that Flash will imminently disappear:
One important HTML5 feature, video, is making a play to challenge the popular Adobe Flash Player plugin software…“I think the disappearance of Flash is closer than people think”
There are numerous reasons why Flash may be a more appropriate way to deliver your video content. Perhaps you need DRM, or adaptive bitrate streaming, for example.
Also, dear journalist/ analyst, it’s fair to point out that there are numerous problems with multimedia on Apple’s iOS:
However, he gives a list of “facts” asserting “These are not interpretations or opinions. These are facts.”
As it’s just possible that another journalist or analyst might be impressed by Forbes’ vehemence and quote these “facts” without question, let’s give them some critical examination.
You do not build a web site in Flash. The only way to build a website is to use HTML pages, and then to embed Flash elements in them.
This supports the author’s thesis that talk of all-Flash websites is an impossibility. Well, yes, technically. But Flash can be embedded using two lines of HTML, neither of which has any visual manifestation (see Blankety-Blank example) so this doesn’t mean much.
Less than half of installed browsers are HTML5 compliant, with different levels of compliance.
As our wikipedia chums would say “Citation needed”. And, please dear Analyst, see above for the absolute necessity to define “HTML5 browser” or “HTML5-compliant”.
The video element in HTML5 is perfect for basic video players, but Flash and Silverlight are much more suitable for advanced video feature (streaming, caption, interactive features and miscellaneous video effects)
Really? I very much like the text-based synchronised subtitles available on things like Playr or mediaelement.js, which are HTML5.
Streaming is also completely possible with HTML5 video. “Miscelleaneous video effects” needs definition before you can claim that HTML5 can’t do them. (It’s been possible to do things like edge-detection, blend, greyscaling for a couple of years with SVG + native video – see http://www.dahlström.net/svg/filters/video/video-filter.svg in Opera, for example).
The iPony Club
Finally, Business Insider has a video in which “Facebook Investor” Roger McNamee exhibits the kind of breathless anticipation about “HTML5″ that is more commonly found in the minds of the prepubescent heroines of a specific genre of children’s fiction as they describe the prospect of riding Misty Mane, their new pony, for the first time. (From 8’58” onwards.)
I address the paraphrases, as they’re what get quoted and picked up:
HTML5 is going to change everything. “In HTML5, an ad is an app, a tweet is an app, everything is an app.” “It’s a blank sheet of paper, and creativity rules again.”
I’m not sure how “a tweet is an app” makes any kind of technical sense. And, much as I like HTML5, this isn’t the Renaissance – we’re not seeing some massive resurgence of human creativity because of a new DOCTYPE.
In HTML5, you don’t need to have display ads: Amazon can have a section of its store as an ad. So if you’re reading a book review, you can buy the book right from the page.
As you’ve been able to do for 10 years.
Because HTML5 can make sites rich and interactive, engagement on a site can go from seconds to minutes.
Flash can make sites rich and interactive. So can HTML 4. The key here is “rich and interactive”, not a particular DOCTYPE.
The iPad is the training wheels for HTML5.
Seriously, have a lie down.
(Added January 2012: the offending video by McNamee:)
ParentPay is, according to its Twitter profile “the market leading online payment & dinner money management solution for schools and caterers, used by hundreds of thousands of parents each week.”
It’s quite a good idea – I load up the account by credit card and, as my daughter buys lunch, the account reduces and I get an itemised bill so I can ensure she’s getting her five a day.
The school are supposed to tell her when her account drops below £5, and she’s supposed to inform me. Somewhere in this chain that involves a computer system, harassed dinnerladies and the legendary communication skills of a twelve year old girl, the system breaks down. Therefore, I rarely find out that funds are low until I receive an accusing text at 8.30 am, or on her arrival home when she tasmanian-devils through the family food supplies because she couldn’t afford lunch.
This morning I had just such an SOS text so went to the website. As usual, I’d forgotten my login details (I really want to use my email address instead of choose a username so it’s less to remember). The password reset showed me a splendidly helpful error message:
Showing techy error messages saying “server errors in ‘/AUTH’ application” and a handy snippet of XML is unlikely to assist a user. However, showing error messages that can identify a specific server technology is of tremendous use to hackers – they know which server and potentially which version number to target.
After 20 minutes trying different username and password combos, I got into the system and made my payment – puzzlingly, to an organisation called “Alliance in Partnership”, on a website called “ParentPay”. Eh? Alliance in Partnership sounds like some barking rightwing thinktank. But I persevere.
I want to like ParentPay. I think it’s a good idea and I hope they succeed. But they need to think more about their customers’ experience. Here’s one tip that would make my life slightly easier.
I know that such a thing is currently beyond human ingenuity and no technology exists that could power such a marvel, but perhaps ParentPay may consider a system that emails me automatically when the account drops below a certain threshold, thereby guaranteeing an uninterrupted supply of bratfuel?
Someone from ParentPay contacted me and said, with admirable politeness, that there actually is such an alert facility but only available at some schools and, once checking that my daughter’s school does offer such a facility, showed me how to set it up.
It’s not easy to find (on the page that tells your balance there is the opportunity to sign up for paid SMS alerts, but no option for emails so I assumed it doesn’t exist), but after verifying my email address I am now signed up.
So I beg ParentPay’s pardon is assuming there isn’t such a system, but suggest that they make it more obvious – I think I’m pretty web savvy and couldn’t find it.
And, in answer to other queries I’ve received, once topped up with money, their system has been flawless over the last 10 months.
My friends think I’m a geek and have stopped reading this blog because of its boring techy content. My family don’t understand how I earn my money.
But I’m not a geek. I didn’t see Tron or the Lord of The Rings. I never play computer games. I’m scared of Git and Subversion. I can’t compile a kernel. In fact, I hate computers—I just love what you can do with them.
When I first started professionally in computers in 1988, I was writing COBOL, FORTRAN, 6502 assembler. There were no GUI tools; everything was command line. That was then. Now, I see no reason why I should need to learn some weird syntax to achieve a simple task.
Exhibit A: I was amused yesterday to read the webP converter instructions for converting imageA.png to imageA.webP. Unless you specify the string “-o”, the converter doesn’t convert: “If omitted, cwebp will perform compression but only report statistics.” What’s the bloody point of an extra switch to make it fulfil its sole function?
I think of non-GUI programs in the same way as I do about going camping. Some people love sleeping in a tent and getting up in the night to walk in the rain to poo in a hole they’ve dug behind a tree. Not me. I spend a considerable portion of my income on a house with a central heating system and three flushing toilets, so there’s no bloody way I’m going camping.
You may think it a badge of honour that you can do “sudo dpkg -i –force-all cupswrapperHL2270DW-2.0.4-2a.i386.deb” from memory. I think you’re burying your turds with a trowel in a thunderstorm.
Operating systems are the same. Despite the fervent wishes and protestations of adherents of operating system X (or Y), each demand that you learn a special way of working to accommodate its own idiosyncrasies. Where the operating systems (or browsers, or Word Processors) agree on a method, it’s not because it’s natural, it’s just a thoroughly-entrenched convention. The Firefox UX blogpost Joe’s First Computer Encounter shows that there are very few “natural” interactions with computers.
So by now you’re wondering why I do this job. “Why, Grandad”, you are shouting in my ear trumpet, “Why do you accept a salary from the geekiest browser out there when you’re clearly 200 years past your sell-by date?”
Because, I reply while drooling onto my cardigan, I love what you can do with a computer. I can use VoIP to call someone anywhere in the world for buttons. I can discuss Shakespeare, furry culture or even HTML5 with someone I’ve never met (and will probably never meet), for free. I can do research, download books, read the thoughts of someone in Iran, or Iraq or Peru or Burma. I can listen to music that would never be commercially released, and I can see photos of anywhere I could ever fancy going, read reviews of hotels and book holidays in an environment which is as close to the micro-economic theory of Perfect Competition as we’ll ever see. Because, at the moment, a computer is my best way to access the Web, which connects me to a third of humanity and, when made properly (accessible HTML isn’t that hard, really), is the most democratic, inclusive mode of communication we’ve ever had.
I hate computers. But I love what you can do with them.
Recording the sessions on video is becoming a custom, and a very good one. Every single session that’s out there as a video increases the knowledge of the web community as a whole, and in the end that is the goal of your conference, too.
I completely agree. Speaking at conferences is a big part of my job evangelising open Web standards for Opera, and videoing the talks is a great way to reach even more people.
So here are some notes on PPK’s advice.
Don’t try to claim copyright
I spoke recently at an excellent event and, as I was preparing to leave, I was handed a release form that granted the organiser the right to publish the video. I always read these, and encourage every conference speaker to do so. It’s lucky I did; a clause in the release form asserted that I grant copyright to the conference organiser, and give them the right to pass on the material to subsidiaries, and “third-party affiliates”.
There are several problems with this. Firstly, and primarily applicable to speakers who are representing their employers: I don’t own the copyright to my talks, Opera does as Opera pays my salary. Also, I have no authority to bind Opera to a contract anyway, so wouldn’t be able to assign such rights away. Most importantly, however, and applicable to most speakers I see: I don’t own copyright for the creative-commons images that I use in my talks, so cannot assign those rights to someone else.
(There is a happy ending to this: when I pointed out the problems to my hosts, they immediately understood and sent me a much simpler agreement that said simply “we will publish the video but make no claim to ownership or rights to the content”.)
Don’t make the video members-only
If you publish videos, don’t put them behind some kind of login or (worse) a paywall. I consent to conference organisers publishing video because it enables those who couldn’t come to the conference to get the content. If it’s only behind a login, it doesn’t get that extra reach.
If it’s behind a paywall, I can’t allow you to reproduce my slides, as some of them are licensed creative commons non-commercial. Now, I’m starting to think that creative commons licenses are so ambiguously worded that it’s impossible be sure that you’re not in breach (see my concerns about sharealike), but to me, using an attributed non-commercial image is OK as long as I’m not directly profiting from that image, eg by selling copies of it or making t-shirts with that design. But I don’t know if it counts as “commercial use” if it’s in a presentation behind a paywall. As I have no wish to be sued in order that someone else can make a profit by restricting circulation of the video, I don’t consent to that video being published. (It’s why one talk of mine was recently published audio-only).
Commercial conferences should transcribe the videos
If you’re a commercial conference, you should transcribe the videos at your own expense so that they’re accessible to people with disabilities. (I don’t mean for grassroots conferences that charge a small entrance fee to cover costs, I mean for big commercial conferences that have a ticket price in the hundreds of dollars).
As part of tarting up Introducing HTML5 for its second edition, I’m discussing the very useful -moz-ui-invalid pseudo-class. The documentation at Mozila Developer Centre is a paragon of clarity and succinctness, so much so that my instinct is to quote the 4 lines “The result is that .. unchanged valid value” with attribution, rather than rephrase it and reduce its clarity.
Share Alike — If you alter, transform, or build upon this work, you may distribute the resulting work only under the same or similar license to this one.
Now, I don’t know whether quoting within a chapter is “building upon” or not. I can’t release the book under a similar license as neither Remy nor I own the intellectual property (we tried to persuade the publishers to release it but they were… somewhat antipathetic (ahem) to that idea).
Twitter chums advised that quoting 4 lines was OK as “fair use”. But I’m in the UK and as far as I can tell, we don’t have that concept here. Wikipedia says of UK “fair dealing”:
Under the Copyright, Designs and Patents Act 1988 (CDPA), fair dealing is limited to the following purposes: research and private study (both must be non-commercial), criticism, review, and news reporting (sections 29, 30, 178). Although not actually defined as a fair dealing, incidental inclusion of a copyrighted work in an artistic work, sound recording, film, broadcast or cable programme doesn’t infringe copyright.
But our book is a commercial project. It’s not criticism, review or news.
So I’ve emailed the MDC to ask them to waive their rights. I’m writing this book as a private individual, and the derisory royalties that technical books produce don’t make me willing to accept personal legal risks: no way am I risking my house, which is the only thing of value I own. (Hiring a lawyer would use up all my royalties.)
This emphatically is not a criticism of Mozilla – they’ve always had an excellent track record of openness and I’m certain they’d be delighted to be quoted in a chapter that praises them.
It’s a criticism of UK copyright law and the Share Alike license which doesn’t define “build upon” or “non-commercial” in any useful way.
For Father’s Day, my daughter painted a picture of me riding a unicorn, with Turkish dancing girl attendant. I’m killing two goose-stepping Nazis with a “lazor gun” below a caption reading “with the power of HTML5″.
It’s going on the door of my newly-decorated office.
Made by someone commenting in Haavard Moen’s post about the announcement of "native HTML5", this video does NOT represent Opera’s official position, but it did make me laugh. Personally, I like "native HTML5". It’s important that it not be tainted with our "modern ways", but preserved for diversity reasons (thx @stommepoes!).
On my old Windows Phone I had a lovely program called MyMobiler to view your mobile screen on your desktop, which you installed and Just Worked.
Not so easy on Android, it appears. I found Android screencast but couldn’t get it working on Windows. So I tried it on Ubuntu; still no joy. When Ubuntu, hacking and things not working coincide, the way forward is to invite Stuart Langridge out to the Opera-Canonical Temple of Synergies and buy him beer while he swears at your machine, Google, Oracle, Ubuntu and anyone in the immediate vicinity. (“Java! You’re a massive cock-bubble!” was one exasperated highlight.)
This took me ages to discover (and hat-tip to Sarah Bourne for the answer) so I’m posting it as it might help someone else.
If you suddenly start getting this error when doing backups on Windows 7, run a full security scan and kill any quarantined viruse. (I use the free-to-download Microsoft Security Essentials.)
Why the error message is so stupidly unhelpful, and why Windows back-up doesn’t simply carry on in the legitimate assumption that you’d rather not backup quarantined viruses, are just two of the many mysteries of the universe.
