Tech journalism, science journalism - tips & thoughts from London Girl Geek Dinner





The recent London Girl Geek Dinner on tech journalism was one of the best and most useful ever, for anyone who writes or broadcasts video or audio - whether or not as a professional journalist - eg tips on how to shoot professional looking video. Thanks as always to Judith Lewis and the team for organising this practical and interesting event, I think the first I've been to since the Regent Street shopping event.

Journalism is still very much a male dominated profession, about 60% male, and in technology and science journalism the percentage is the same if not worse.

Equally bad is the fact that, as the attendees agreed, far too many technology magazines and journals are seemingly aimed just at men (see my rant on tech magazine sexism in GirlyGeekdom - about T3 magazine, which I don't subscribe to anymore, quelle surprise. And, while I'm at it, much stuff aimed at women seems to be designed by men too, like pyjamas. Humph.)

Even Wired UK, who provided for the event free copies of their mag and some discounted subs, received some criticism for being written almost exclusively from a male perspective.

It seems that the market is nicheing or fragmenting. There is probably room for a magazine which caters for (or at least doesn't ignore) the growing female appetite for technology - indeed it's likely to be welcomed with open arms, at least by the attendees!

Now on to the individual talks.

The 3 journalists / broadcasters, who kindly gave their time to share their experiences and tips with us, were (in order of appearance) Angela Saini, Connie St Louis and Ramaa Sharma, and all of them have been or still are connected with the BBC.

Angela Saini - tips on being a journalist

Angela Saini, now a freelance journalist and author (blog), gave some practical tips on how to be a technology journalist or science journalist (her own background is engineering).

She doesn't seem to have put her slides online. I didn't make many notes as most of her points although very good and helpful seemed to be common sense to me.

Interestingly she was quite firm in her views on the distinction between bloggers and journalists. If you just sit in front of a keyboard, you're not a journalist. You have to go out there, collar and interview people, get exclusives.

See more on her blog post after the event, which also repeated her argument that the quality of media and news generally is going downhill as journalism is being devalued, both by "churnalists" who just copy and paste official or corporate press releases, and by people willing to work for free - interns as well as bloggers.

She thinks that journalists should demand to be paid, and paid fairly, for their work. (Apparently tech journalists generally get paid about 40 or 50p a word in the UK; more in the US.)

Surely editors and readers are partly to blame as well, for putting up with things like churnalism?

Connie St Louis - journalism qualification

Connie St Louis (blog), while still producing radio programmes for the BBC etc, is in charge of the Science Journalism MA at City University's highly regarded Department of Journalism. She too has a science background, in biology.

These days it's getting harder and harder to get a job in journalism, and having a formal qualification like a postgrad degree in journalism is one way to get your foot in the door.

The National Union of Journalists also offers training (it seems a bit chicken and egg to me though, if you have to have a journalism job before you can be an NUJ member, rather like trying to get an Equity card - not that I have one of those either).

Connie's Department also does research on journalism and media. One fascinating current project of hers is looking at the prevalence of churnalism by running plagiarism detection software on "news articles", as the source news releases are usually published online. The results will be published probably next year.

I'm looking forward to seeing them. I must say I had noticed the phenomenon myself, as I now subscribe to science / tech related news releases where I can, and had spotted the striking resemblances between many so-called news articles and the official news releases.

I don't read press releases so that I can copy them into blog posts - I don't hold with that, and never have. Too many people do it, bloggers as well as some professional journalists. In my view, either be the first to break the news, or else produce thoughtful reasoned analysis about it (which takes time and research). Don't just play "follow the leader" and repeat the press release or the first person who wrote about it.

I subscribe to news releases because I believe in getting the info straight from the horse's mouth as it's more likely to be accurate and reliable (assuming the body issuing the release isn't lying of course!), and more importantly it's less likely to be garbled or taken out of context - unlike in many secondhand reports, I have to say.

When blog posts or news stories don't provide links to the full original source, I really don't like it - there's no excuse for it, especially on the web (so what if "a government paper said…" - what's the full title of the paper, what department issued it, where can I get a copy?).

I often try to track the sources down for myself. In my own blog posts I certainly always try to link to the source where possible, so people can check the original if they wish, and hopefully see that they can trust my rendition.

Of course, it now seems obvious why many media articles don't link to the original - maybe they're worried readers will spot that they've just been copying press releases wholesale!

Ramaa Sharma - gadgets for multi-media journalism

Ramaa Sharma, who now teaches journalism internally at the BBC, is living proof that you don't always need a science background to get into tech journalism.

These days journalists have to be able to do stories for the web as well as TV, radio and print; and they not only are expected to write the stories but also to shoot the videos, record the audio and do the editing and uploading.

Ramaa gave us some very useful tips on multimedia journalism, including tools which don't cost the earth and won't break your back lugging them around.

In my view the latter is a big factor, not just for people who've done their back in like me, but also because making the gear that you need for the job too huge or heavy can be a deterrent to women, as we're simply not built like men.

Her recommended equipment included:
  1. Benk tripod - brolly sized and lightweight, yet opens out (to oohs and aahs, virtually) to quite a decent length. She said she got it from Maplins but I can't tell if it was this or this or indeed neither, as neither says "Benk" in the photo or description and they both cost the same, just £19.99).
  2. Gorillapod - a range of tripods for cameras as well as video cameras; basically a small tripod whose legs can be wrapped round almost anything. (If I were T3 I'd probably be making a "joke" about that.)
  3. Kodak Zi8 HD Pocket Video Camera - relatively cheap at under £100, very portable, now used by the BBC following her comparative review of this camcorder, the Flip and the iPhone. It even has a socket for a separate mic which the others don't. BBC WorldWide's poignant video about the Afghanistan dancing boys was shot using one. The only con with this kit is, you can't monitor the volume or quality of the audio live as you're recording it, for audio limiting; but she wouldn't be surprised if the next model had this feature too.
  4. Mic - most microphones will work with the Kodak, the one she had with her was a BeyerDynamic MCE 58. And from my own experience, don't forget that all important microphone shield or cover to minimise wind noise etc.

Her tips on shooting video that looks professional include:

  1. Keep the camera steady - don't be tempted to follow the subject around if they move, frame it carefully and then hold still. And shaky video is a no no! Hence it's important to use tripods, as to which see below.
  2. Take a mix of shots - at least one long distance shot, a medium distance shot and a close up shot, each one for about 10 seconds minimum; they can be used in your edits.
  3. Should be an obvious one, this - but don't have the light behind the subject (eg shooting in front of a window), have the light behind you.
  4. Video editing tools - when people asked for recommendations she suggested Final Cut for Mac, Adobe Premiere Pro (eek at the price, I say!) or Adobe Premiere Elements for Windows. (And here's me wiv Windows Movie Maker…)

You can hear these tips and more on Ramaa Sharma's video on pocket-sized video journalism.

Future Girl Geek events

The best way to find out about future LGGD events, which are generally free thanks to the generous sponsors, is to sign up for the London Girl Geek Dinners mailing list.

If you're male you can still go, as long as you're accompanied by a responsible female ;D (who signed you up for the event). I'm open to suitable bribes…

There are Girl Geek Dinners all over the world, just search to see if you have one locally.

Help evolve music: experiment - take part!





Want to take part in a fascinating experiment to evolve music? You have 1 more week to try it…

If you've not heard about it already, on the DarwinTunes website professor of evolutionary developmental biology Armand Leroi, in collaboration with musician Brian Eno, is running a "cultural evolution" experiment to try to evolve songs by "natural selection", modelled on evolutionary studies in labs of microbes and small animals (worms, flies). The video outlines what they're doing.

Who provides the "natural selection"? You do. DarwinTunes is a computer program, a Perl genetic programming evolutionary algorithm system developed by bioinformatician Dr Bob MacCallum based on his evolutionary system Evolectronica. (More on the technology behind DarwinTunes.)

The program randomly created (generated) a pair of songs, then let them recombine, mutate and "reproduce" to produce 100 "descendant" songs - normally each song is a loop of 4 bars in 4/4 time, played to you 2 or 4 times for rating.

You can hear examples of the starting populations (and I can't resist pointing out that this experiment obviously doesn't involve paying any heed to the condom ringtone, then!):

Visitors to the DarwinTunes site rate songs, and according to the ratings the worst songs are killed, the best are allowed to reproduce and then die off, and visitors can then rate their offspring, and so on.

There are examples of evolving hand picked "good" loops on their news pages (after 8000 ratings, 9000 ratings, for the rest see their news!).

Something I've noticed - the evolved songs all seem to be in C major. Is this because the starting population was mostly in C major? Or do humans just like that key…? (indeed, have we become genetically predisposed to like C major after generations of playing the easier white keys on pianos?)

If you want to have a go, the experiment has about a week left to run, so grab the chance to try rating songs to influence their evolution!

I can't wait to hear the results - you can keep up via their news pages or their Twitter account.

Vocal extraction - hear Vera Lynn reorchestrated





Very interesting - Audionamix ADX Technology isolated the vocal track from Dame Vera Lynn's iconic 1930's mono recording of "We'll Meet Again" for record label Universal Music, and worked with Universal's sound engineers to:

"clean up and re-master the voice track into a high definition stereo component. This was seamlessly integrated with the new orchestration and the contemporary Fron Male Voice Choir. The whole project was completed within a week…

Audionamix has previously worked on movie soundtracks, such as the Oscar winning The Passionate Life of Edith Piaf. On this project, the film makers wanted to use the original sound recording of Edith Piaf singing. Audionamix separated out the voice tracks while conserving all the original elements in order to remix these into the 5.1 surround sound technology of the film."

You can hear a couple of lines from the original track, then just the isolated vocal of the same lines, then the remixed re-orchestrated version of those lines, on the Audionamix site: click here or click on the pic above.

Christmas 2008 wishlist - top 10






Dear Santa

Most of the stuff I'd like for Xmas isn't actually easily available, if at all. You know me. But hey, don't you like a challenge? And it's not impossible to get them - the technology's up to it, it's just that no one is making them. Or making them anymore. Or, maybe, I just don't know where to get them from.

Yep - the things I want the most are things that could be, but aren't. Or things I used to be able to get, but can't now (why oh why do they stop producing good stuff, anyway? Classics will never stop being in demand).

So here's my very random X'mas wishlist: high tech, low tech, or just no tech.

(I'll leave out pyjamas that button up all the way to the top and my even more specific requirements as to undergarments, for now. And the answer to why there's no single word for "trouser leg" when we use "sleeve" instead of "shirt arm"!)

10. Motorbikes / scooters - big wheels, reverse gear, fuel gauge and clock

Why do most scooters have tiny wheels that make you feel every bump in the road? Is it because, hey, scooters are mostly for women (who wouldn't throw their dainty legs across rough, tough motorbikes, oh no), and women have more cushioning in their nether regions don't they, so they can like it or (literally) lump it?

Well never mind women, think joints. For both genders. It ain't that easy to get your leg over, so to speak. Especially as you get older and creakier. Scooters are much easier that motorbikes in that regard. But not if bumpiness cancels out that advantage.

Why can't they make more scooters with bigger, more stable wheels, dammit? And more powerful scooters with bigger engines, too.

And while I'm on the subject, why don't all scooters and motorcycles come with a reverse gear and a fuel gauge and built-in clock as standard? (Crash helmets, well, you just have to keep trying till you find one that fits your shape of head.)

A friend also whinges about many motorbikes being too high for most women, and indeed many men, even if you get the seat lowered to the lowest possible height. Maybe BMW and the like think that their image would be tarnished if anyone less than a beefy 6 foot tall man was to be seen riding one of their bikes around. But in these economic climes, wouldn't it be better to sell more bikes to the many shorter people who'd buy your brand if only you made motor bikes that were lower in height? Especially tourers.

9. MP3 recorder / player with Mini Disc-like editing

Because I record speeches at BarCamps etc, or rehearsals, or (with permission only of course) shows e.g. concerts I'm singing in, I want an MP3 / WAV recorder - not just a player.

I do have one (a Zoom H4 Handy Recorder field recorder, photo below), but it's quite bulky and not very user friendly in its controls especially in terms of recording and playback.

Zoom H4 - photo from Wikipedia, by Ed Poor

It would be great to have a small, user-friendly music player that also has decent recording facilities - built-in microphone, line in, with high quality recordings (or better still selectable quality) - particularly if it's geared for vocal recordings. It should handle as many formats as possible - MP3 and WAV minimum - and take memory cards that are 2 or 4 GB in size, ideally bigger. And could I have one at a reasonable price, pretty please?

So far, so possible. But what I've not found yet is a portable MP3 /WAV recorder that has editing features as powerful and flexible as you could get with the now pretty much dead MiniDisc format. I'm talking really easy divide, combine, erase, move of tracks. To quote Wikipedia:

"MiniDiscs can be edited very quickly even on portable machines. Tracks can be split, combined, moved or deleted with ease either on the player or uploaded to PC (only with the latest version of Sony's PC based SonicStage V4.3 software) and edited there."

I hope we'll get that in the future (and bookmarking specific spots in tracks for playback would be great too). A player / recorder combined with DAB radio and the ability to record from the radio would be the icing on the cake. But better editing on portable recorders will do me just fine!

8. Huge, microwaveable, dishwasher safe coffee / tea mugs by Brookshaw

I like a huge cuppa tea. Or coffee. Most mugs are too small for me.

I thought I'd found the ideal mug when I came across Dunoon Stoneware's "Nevis" range with a big 0.48L capacity and lovely large handles.

Thing is, I liked Jane Brookshaw's cheerful bright animal cartoon designs the best. In fact I loved them, and still do. They make me smile. I bought one or two of every single design in her range.

But, I can't replace my chipped mugs because Dunoon don't do those particular designs anymore (just wishy washy pastel ones, or mugs with less comfortable handles, or mugs that are simply too small).

Bring back Brookshaw's punchy funny designs, please! I'd buy more, I really would. It's an own goal there for Dunoon because I don't buy their mugs now. Yet I would if they still sold the classic Brookshaw range, pictured below (photo by me, licensed under CC - see bottom of page).

7. Straight backed low chair (see, I did say "no tech"!)

It seems impossible to get a chair that has a 90 degree angle between seat and back. They all slope backwards. I know it seems to be received wisdom these days that a 135 degree angle is best for the back, but I still want a straight back chair.

As Alexander Technique practitioners will tell you, a straight backed chair is useful for Alexander. I'm no expert but learning Alexander Technique has really helped me, though I'd be the first to admit I don't do it often enough.

But it's near impossible to find a totally straight backed chair in the UK. Like I said, they all seem to slope at an angle. I'm still looking.

(And I need it to be low because I'm short, and on most chairs made for grown ups my feet don't touch the ground!)

6. Old-fashioned roller skates, updated


(Credit: photo by bulldog1, licensed under an Attribution-Noncommercial-No Derivative Works 2.0 Generic Creative Commons licence)

Remember those skates you could wear over your trainers? I want something like that, portable, lightweight, easily removable and packable away, which you can slip on quickly over your shoes when you emerge from the Tube. Wouldn't that make commuting much faster? (if perhaps more risky for those people who won't get outta mah waaaaaay!).

Better still, comfy roller shoes with retractable wheels which pop out with the push of a button, and just as easily pop away again.

I've seen some but they're not easy to walk in or the wheels are too flimsy, like toy skates. I want real, usable, hardwearing ones.

And it's got to be quad i.e. four wheels, for extra stability. As I probably will fall over, given the chance. (I tried Heelys, once. Couldn't keep my balance and nearly had a heart attack. Cross that one out.)

The closest I've come across online are Aircoast sneakers but I don't know anyone who's tried them (and their site somehow doesn't inspire confidence in me - plus, their roller skate shoes are out of stock, not a good sign). The idea of electric powered roller shoes sounds excellent to indolent me, though!

(Talking about footwear, I've given up on LL Bean Puff Boots. Best indoor slippers I ever had: warm, comfy, hardwearing, you could step in and out of them easily, but they don't make them anymore. They'd probably be on my wishlist if I thought there was any hope of their being manufactured again. Which there isn't.)

5. Hip belt bag / holster for large PDA / mobilephone / cellphone

I lurve my gadgets but I don't want to be too weighed down carting them round in a backpack or bag.

I've tried Krusell cases; I've tried (and hated) the possibly fashionable but definitely impractical UrbanTool hipholster, which I rated as more for victim than fashion. No luck there.

I don't want a bag that you have to thread through a separate belt (I may not always want to belt my jeans, for a start).

Nope, the belt bit needs to be integrated, in my view. So that I can just strap the whole thing on in a jiffy. (No sniggering, you there at the back!)

So, I think they've got the right idea with "bumbags" ("fanny packs" I believe the Americans call 'em, and no sniggering again I say!). I don't care that they're the height of unfashion.

I like that you can strap the bag round your hips just by clicking the fastening into the buckle or clasp. Easy release too. Perfect. That's the sort of thing I want. No hands needed, and hips can take the load far better than shoulders or back, so they're much more ergonomic too in my view.

However, they need to be larger and stronger, and have big enough pockets / compartments for gadgets not just a purse (and have several pockets not just one). The fastenings have to be made of strong metal too, not plastic. (I've used bum bags with plastic buckles for phones etc. Trust me, the plastic teeth bend, the clasp slips out, and the whole thing falls down!)

A nice strong shoulder holster would be a good possible alternative - but with pockets or holders / holsters suitable for gadgets rather than guns, obviously.

The closest I've seen are these Happy Cow belt bags ("Happy Cow", I know, I know!), some of which even convert into a holster - but you can't click it on and off easily, and I'm too lazy to put on a belt with a tongue etc. I want an easy snap on / off fastening, just like on a bum bag. And I want zips for the pockets, not buttons.

So, I'm still looking for the ideal cellphone / gadget belt. One day, I may well have to get one made to order.

4. Endless Pool

Treadmills for runners and stationary exercise cycles are all very well, but I'm not much of a runner or a cyclist. Yet I'd still like to keep, err I mean, get, fit.

I swam a lot in my teens. Almost every day, in fact. Never up to swim team speeds, but I was very at home in the water.

But I've not swum for years now.

Partly because these days most public pools are too cold for wimpy me (I tried a posh hotel pool once - weekend in the hotel courtesy of my then employers. Beautifully warm, bliss!).

And partly because I've become more and more fastidious with age. When I think of pools, I'm immediately reminded of a brilliant Private Eye cartoon I once saw, of a public pool with separate lanes labelled something like: "Veruccas". "Plasters". "Other people's wee".

You understand why I'm not exactly drawn to swimming these days.

But, I'd love to have a private swimming pool. I'm talking a tiny pool that's like a treadmill for swimmers, which generates a perpetual current you swim against: the Endless Pool swimming machine. Unlike many of my other wishlist items, this is something that you can get, even in the UK. My place just isn't big enough to have a "real" pool, but maybe it's possible steal a small patch from an already small garden?

And oh, Santa, while we're on the subject, the £13,000-plus needed to pay for an Endless Pool (and to put a roof and walls round the bit of garden, as an open air pool in England is to me only for the terminally masochistic) would also come in handy!

3. Virtual machines for the masses

I've loved the idea of virtual machines since I first heard of them a few years back, where you can run different operating systems on the same hardware as "virtual machines". As Microsoft put it in relation to their Virtual PC 2007 product, you can:

"create separate virtual machines on your Windows desktop, each of which virtualizes the hardware of a complete physical computer. Use virtual machines to run operating systems such as MS-DOS, Windows, and OS/2. You can run multiple operating systems at once on a single physical computer and switch between them as easily as switching applications—instantly, with a mouse click."

But I have in mind not so much being able to switch between different operating systems (which could include Linux etc as well as Windows), as being able to use virtualisation for security and convenience - even if you run just the one operating system on your virtual machine.

Wouldn't it be great if you could run a base operating system like Windows XP, on which you could install your favourite programs, and then use it to your heart's content - but if anything goes wrong or it slows down (or it catches a virus or other malware), you can just wipe it all out with a few keystrokes or mouse clicks, and then quickly and easily reinstate a fresh, clean (previously-saved) copy of your virtual machine with all your favourite programs already on it?

Virtualization technology does exist now, e.g. the open source VirtualBox, or the fairly well known VMWare, but it seems to me that it's still not quite there yet, especially in terms of the average consumer being able to use it effectively, easily and reasonably cheaply.

I hope it will get there sooner rather than later.

2. Proper mobile internet, and non-geographic mobile phone calls

There are 2 things I'd like to happen in the mobile industry, from a consumer viewpoint.

Mobile data charging

First, I wish that UK mobile phone network operators would offer combo voice, text and data price plans.

Plans like T-Mobile's Flext do let customers use their monthly allowance for voice calls and SMS messages in whatever combination the consumer wishes, but data isn't included e.g. mobile Web or email access. It really should be.

To me, that would be a lot fairer than so called "unlimited" data usage plans which really aren't. And people would be paying for what they're using, within their allowance.

Alternatively, if truly unlimited data at a fixed monthly tariff were a reality (rather than a pretence), it would really help the mobile internet take off - which would be good for all involved.

Calls from mobile phones to non-geographic phone numbers

Second, I've always thought it was unfair that consumers who use a mobile phone to call a non-geographic telephone number (0845, 0870, 0871 and the like) get charged more than if they phone via a landline telephone, and furthermore that the cost of that call is not within the customer's inclusive minutes allowed for the month, but is charged extra on top of that.

My wish here: they should cost the same as geographic numbers, and be included within the standard voice call allowance (unless they're special premium rate numbers whose much higher rates are clearly made known to the consumer).

Of course, businesses advertise those telephone numbers and make consumers use them because of "revenue sharing" - the business who is called gets a cut of the (higher) price paid by the consumer to the telephone company or network for the phone call.

In May 2008, as a result of consumer concerns about the lack of transparency on the cost of calls, UK comms regulator Ofcom did consult on changes to 0870 and on Extending Premium Rate Services Regulation to 087 Numbers (see the news release "Tightening the rules on 08 telephone numbers": 0870 charges should be reduced and tariffs better displayed and 0871 numbers subject to new regulation).

However, disappointingly in October 2008 Ofcom decided to suspend work on 0870 call charges. While they said they aimed to "publish a further statement on implementing any changes to 0870 policy by the end of the year... " and "publish a statement on its proposal to bring the most expensive 087 numbers (including 0871, 0872 and 0873 numbers) within the remit of PhonepayPlus, in the autumn", it's now nearly Christmas and there's no sign of either statement.

I don't know why Ofcom aren't protecting consumers by putting a stop to this very obvious "rip off" (as many have called it, for years) - there was an attempt in 2005 which got nowhere, and I fear that this latest effort will go nowhere too.

More consumer organisations (like the Communications Consumer Panel, formerly the Ofcom Consumer Panel) and consumers ought to lobby Ofcom and the government on this issue. Meanwhile, we consumers can try to protect ourselves by using (and contributing phone numbers to) Say No to 0870 - a site which lists geographic alternatives to non-geographic numbers. If you call the geographic number instead, it will be included in your inclusive minutes, so obviously you're better off using the geographic number, especially when calling from your cellphone.

It's not all bad news - Ofcom recently tried to publicise the use of 03 phone numbers, which are "real" non-geographic numbers. They're non-geographic numbers which consumers can safely use in the knowledge that calls to them aren't charged more than calls to national rate 01 or 02 numbers, and furthermore will be counted within the customer's inclusive minutes. (Ofcom itself has 03 numbers for the public to use to contact Ofcom.)

Indeed, recently (as Ofcom noted) the UK Department of Health issued a consultation on the use of 084 telephone numbers in the NHS, as they're considering banning the use of 084 numbers to access NHS services because, as they put it, "patients who use 084 numbers are paying more than the equivalent cost of a local rate call to access services provided by the NHS". The consultation ends on 31 March 2009 so if you're interested in this area, please do consider responding.

Of course, that doesn't mean that non-government departments (or indeed government departments outside the NHS) will start using 03 numbers instead of 084 numbers. But I hope it's a sign that momentum towards 03 numbers is building up, at least within some government departments. I'm a bit more cynical as to whether private commercial businesses will adopt 03 numbers unless the regulators make them.

1. Truly mobile computing - and Net access everywhere

For this biggest wish of mine to come true, a number of things will have to happen.

  1. Mobile computing devices need to get lighter and more usable and allow faster, more efficient data entry - but in my view netbooks aren't quite it, nor smartphones. Convergence of mobile devices is on its way, but who knows how long it'll take.
  2. Internet access needs to be ubiquitous - we need truly mobile, flexible, full Net access everywhere, at decent speeds, without having to pay a fortune or being forced to hunt out WiFi hotspots. Including free public wifi and full mobile phone / cellphone coverage in Tube trains and on Tube platforms, which is well worth putting up with "Honey I'm on the Tube" for, in my view! And as I've said above, unlimited data access including Web, bulletin boards, chat etc. That would be the real killer app for wireless.

We're certainly nowhere near there with wearable computers yet. For visual output devices, a.k.a. monitor screens, there are video glasses or head mounted displays like the Vuzix iWear "video eyewear" "personal video displays", but these headsets don't (yet) connect to computers, only DVD players, gaming consoles and the like. And you can't wear them if you wear glasses (they could make them like sunglasses that fit over regular spectacles / glasses, but they don't seem to yet.) Plus, some people just don't want to look like a cyborg. Believe it or not.

More small laptops (i.e. UMPCs, mini-notebooks, subnotebooks or netbooks as they're variously called) have become available this year, at long last - triggered in part by the (to me, not at all unexpected) phenomenal success of the Asus Eee. Problem is, any portable computer that's just over 1 kg in weight is still too heavy for me, and their size is still too unwieldy when you're standing up on the Tube.

By the way, if you're in the market for a sub-notebook, I wouldn't recommend the Eee myself, because I feel Asus messed their customers round. And I'd also strongly advise against the Vye PC: much as I'd like to recommend a small British company which makes what at first sight seems a nice product, the "support" I got, even from the supposedly customer-friendly USA, was nothing short of appalling, and what should come as standard with the model I bought, didn't. However, people I know with true tech expertise have actually bought, and liked, the Acer Aspire One - so it's probably worth a try especially if you want to use Linux

It's also interesting that recent models of the Acer Aspire One even come with a SIM card slot so you can use it for mobile internet if you have a data plan with your mobile phone network provider.

But, it's still too large and heavy for what I want.

It will come as no surprise to regular readers that (as I've said many times before) the device I most crave is a handheld computer / H/PC / palmtop computer along the lines of an updated Psion 5mx, with the same weight, form factor / size and long battery life, and the keyboard exactly as it is, but with added mobile phone SIM, wifi, Bluetooth, email, fully fledged web browser (with Javascript and Java), and colour screen (with backlighting), which runs at a decent speed. User friendly. Sold at a fair price. Which lets you use third party applications e.g. your preferred email or chat / Twitter client. And allows easy transfer of data to and from a desktop computer with copy and paste.

(As an aside, one feature of a Psion application, Datasafe, which I really like is that when you leave an open password-protected page by switching to another application, when you switch back it asks for your password again. For better security all password-protected documents on all operating systems should do that, in my view.)

(Another aside - it may seem a minor point but devices, especially smartphones and the like which are aimed at business users, must be able to be made silent, and stay that way, when in a quiet environment - like a classical concert! No hidden nasties that spring to life suddenly despite your best efforts. That was a major defect of the Nokia 7710, that if you turned it on (e.g. to check email during a business meeting) it played the Nokia "welcome" tune and you just couldn't disable that.)

The Psion 5mx was more than just a PDA and I'm still waiting for someone to deliver a modern computing device that has the features and advantages of a 5mx.

It's light and portable. Only 350 grams, including 2 AA batteries, which last for 15 - 20 hours. That's right, hours.

It's "instant on" (and off), whereas my XP computer takes at least 15 minutes to boot. It even saves stuff in RAM if you forgot to save before you switched it off, though obviously it's a good idea to always remember to save.

Zoom features are built in, so you can zoom in and out of any application - essential for something that doesn't have a full sized screen.

The landscape screen is perfect for Web access.

But most of all, I need easy, quick text input via a decent built-in hardware keyboard, or at the very least a non-miniscule onscreen keyboard with non-losable stylus (attached with a retractable cord perhaps!).

Why? Because two hands are still faster than one. Touch typing on a QWERTY keyboard is much faster than linear speech, even though voice recognition (speak orders to your computer?) is progressing. Mobile phone keyboards I use only when I have to, not because I want to. I don't reply to SMS texts as quickly as I should because most phone keys are too painfully slow and error-prone to pick text out on - even with predictive text.

The 5mx's integrated slide-forward keyboard is a design classic, a real keyboard with proper travel, which you can touch type on (at least if your fingers aren't too sausagey). An add-on Bluetooth keyboard might be livable with if it was very small and portable and had good travel on the keys. A decent on-screen keyboard like the one on the Nokia 7710 smartphone might do too, as long as it came with with non-losable stylus (attached with flexible cord!).

Granted, something the size of the 5mx would be a bit bulky to be used as a mobile phone: it wouldn't be very comfortable to hold to your ear. But that's exactly what Bluetooth earpieces / headsets are for. Keep the device in your bag or pocket (or belt bag, dare I say!), and use the earpiece for phone calls.

0. World peace

Just in case you thought I'd forgotten that one. (Hey, it seems a lot more likely than getting an Obama for the UK, anyway.)

Happy holidays, one and all!

Stupid Aid: misuse of "security", "data protection", "health & safety"





In a separate post I had a moan about security questions asked by banks and the like being too easy for bad guys to answer, and identification requirements not making much sense.

But, many of us have also experienced the opposite syndrome.

Unnecessary security questions

Most of us have had to deal with organisations whose security policies (or their implementation) result in unnecessary security measures, insisted upon by jobsworth staff in certain businesses, who seem to delight in forcing time-poor customers to recite their name rank & serial number (& even more) before they'll deign to answer any questions about the company's products, services or terms.

Yes, even when the question is clearly very general and could be answered (by someone who knows what they're doing, at least) without any access to a customer's account or personal details - e.g. what are their current interest rates?

Then the jobsworth acts like they're the injured party if you try to point out that it's unnecessary to go through all that before they can deign to answer your particular question. (They'll insist it's "data protection" or "standard procedures", usually.)

UPDATE: of course, how could I forget, a friend just reminded me - once you've managed to get through one raft of security questions before they'll condescend to put you through to the right department, you guessed it: the next department then makes you go through all the same questions, all over again. And so on for the next department. Why on earth can't they just have one security check per call or contact? It's the same with credit card enquiries where you have to enter your long credit card number, date of birth etc on the telephone keypad first before they'll even add you to the queue of calls waiting to be answered. And when you finally get to speak to a real human being, they make you give exactly the same details all over again (including your credit card number and birthday that you'd already input before). Stupid, and exasperating.

Data protection

A related problem is when jobsworth call centre employees refuse to give out information about a customer to any third party, not even the parent of a child, or the close relative of a sick elderly person, "because of data protection". A friend has to deal with matters on behalf of a seriously ill family member who isn't physically capable of it, and the hoops that some people try to make my friend jump through are unbelievable.

A silly but true recent incident, which got some media publicity and was cited by the UK Information Commissioner's Office as an example of misunderstanding data protection, was when Marks & Spencer's staff refused to talk to a mother about a missing belt on her 7 year old son's Superman outfit "because of data protection" - forcing her to get him to come to the phone to give his mum permission to talk on his behalf!

As the ICO pointed out (my emphasis): "Whilst it right for organisation to be careful before releasing personal information, this case demonstrates an absence of common sense. In the circumstances it was obvious that the seven year old child would not have ordered the Superman suit himself. Marks & Spencer were not being asked to release any personal information: they were simply being told that a belt was missing from the order."

The ICO also pointed out some other examples of data protection rules misuse when urging organisations (my emphasis) "not to hide behind the Data Protection Act unnecessarily when dealing with individuals" - what the ICO calls "data protection duck outs" like "parents not being allowed to take photos of their child at a nativity play; teachers unable to promote the successes of pupils in the local media and priests prevented from praying for an ill person by name during mass", insurance companies refusing to send out a claim form if requested by someone other than the policy holder, and exam boards refusing to give a child's exams results to the parent (or indeed the child herself - only to the teacher, who'd entered the child for the exam!)

The ICO "data protection duck-out" note is worth a read as it points out some other data protection myths - it seems to be an update of an earlier ICO note on data protection myths and realities, also worth a look as it gives some other examples not in the later note (though unfortunately it's undated).

Now usually the stupid data protection duckout is probably not as bad as security questions which are too easy for bad guys to find out the answers to, as most of the time it's more annoying, irritating and time-wasting for consumers than outright dangerous.

However, there have been cases where it has had dire real life consequences. In 2003, 2 pensioners, George and Gertrude Bates, who had funds but were forgetful, died after British Gas cut off their gas for non-payment - and didn't tell social services about the disconnection because they thought the Data Protection Act didn't allow it. The ICO myths and realities note also noted complaints that "a gas or electricity company will not tell them whether their elderly relative or neighbour is in arrears and in danger of being cut off" using data protection as the excuse.

Another example (see e.g. Out-Law article) which is also well known - in 2004, Humberside police blamed the Data Protection Act for their failure to record information about 9 prior allegations against Ian Huntley, school caretaker and convicted murderer of schoolgirls Holly Wells and Jessica Chapman, who may not have been given that job if that information had been known.

The ICO have at least since produced a "Data Protection Good Practice Note: Providing Personal Account Information to A Third Party" which gives some examples of good and bad practice in this context, as part of a drive to produce more practical and user friendly guidance etc, but in my view a lot of it is just down to using common sense.

"Data protection" has also been used as an excuse by some public bodies hide information about their position or actions from the public. The European Ombudsman has expressed concern that European data protection rules were "being diverted from their proper purpose of helping to ensure respect for the individual right to privacy.. Instead, they are being used to undermine the principle of openness in public activities."

While that letter was written in 2002, it still holds true today: "data protection" should not be used to prevent the public from finding out information to which they are entitled. (In that context, the relationship between data protection and freedom of information is not an easy one, and in the UK the tension between them was considered in July 2008 by the House of Lords in Common Services Agency (Appellants) v Scottish Information Commissioner (Respondent) (Scotland) [2008] UKHL 47. I've not read it yet but it seems that it isn't necessarily much clearer how the balance between the two can be struck.)

National security

Another type of unnecessary restriction "for national security" relates to "security" guards and the like preventing people from taking photos in perfectly public places, notably transport hubs - train stations, bus stations etc. Recently I witnessed London Transport staff stopping a tourist in Liverpool Street Station from taking a photo of their companion outside the Tube barriers! (And see this Guardian comment on the difficulties faced by a white female photographer openly trying to take publicity photos of a (non-white) man in central London.)

That's really stupid. The smart way for a real terrorist to take pictures of intended targets would be to use a small concealed camera, hidden "spy cameras" are easy and not expensive to buy, ,and so tiny these days that no one would notice. And I've no doubt a lot of terrorists are smart. If someone is openly snapping pics, why on earth assume they must have some evil purpose in mind? And how would fuzzy pics of a Tube barrier help a bad guy, honestly?

(Digressing further, I also think it's stupid that because of the UK Criminal Justice & Immigration Act 2008 section 63 you can now be a criminal for just possessing "extreme pornographic images" of things which, if you did them, would be perfectly legal to do, even if others might think they were grossly offensive, obscene or disgusting. How can merely having a photo of something be worse than actually doing it? Though I'm not advocating evening it up by criminalising "obscene" acts! On the contrary, I think what adults do in private with informed consent is their business. Possibly, even if it's potentially life-threatening - look at dangerous "manly sports", they're perfectly legal aren't they? Double standards still rule.)

Does technology or modern life make you stupid?

Now on to stupidity and technology / the complexities of modern life and living.

The ICO had thought it appropriate to mention the DP duckout at the start of "Stupid Aid Week" (1-5 September in 2008), whose slogan is "Make Stupidity History".

Stupid Aid Week was started in 2007 by public relations consultant Andy Green after he "asked [in a restaurant] for a slice of lemon in my water and was told I couldn't have one because it would involve using a knife and that would mean carrying out a risk assessment... Stupidity is not about low intelligence, it's about inflexible thinking without asking questions... Whether it's being told 'the computer says 'No', facing an unhelpful call centre hiding behind 'data protection', or just inflexible 'jobsworths'. I'm trying to get people to stand up for themselves more and not be fobbed off."

Other examples he's given: a car running into another car because "the sat nav didn't show the T-junction"; and not being able to make a doctor's appointment more than 2 weeks in advance because the computer only allowed scheduling for up to a fortnight. And top 6 excuses for stupid decisions or stupid thinking (including "it's health and safety"!)

As he puts it, is technology (to which I'd add complex "data protection" laws and the like) getting in the way of common sense?

While his "Flexible Thinking Forum" is billed as a "not for profit social enterprise enabling businesses and organizations improve their people’s creative thinking skills", it doesn't seem to involve more than 1 person; there's not been much mass takeup of his Stupid Aid campaign (e.g. as I write no one has suggested even one example of stupid thinking on his submission page yet) but it's certainly an excellent way for him to promote his consultancy practice and his new book Overcoming Stupidity in the World Around You: The Stupid Aid Survival Guide, which is described as aiming to provide "practical tools, tips, ideas and inspiration of what to do when you are faced with examples of bureaucracy gone mad, daft decisions, or inflexible ‘jobsworths’". (No, I haven't got a copy.)

It's very clever indeed of Andy Green to get free publicity not just from the ICO but also from the AA and from the Institution of Occupational Safety and Health for his Stupid Aid Tour 2008 and book launch, but then he's a PR expert! (Though what's less clever is that he hasn't directly linked from the book's page to where to buy the book, and the press release for the book launch is only available in full in DOC format.)

By the way, I like the AA stupidity examples like councils wasting employee time and money painting double yellow lines in spaces so small that only toy cars could park there. And the IOSH is sponsoring, for a second time, the World Conker Championships on 12 October 2008 at Ashton, near Oundle, Northants to make the point about "health & safety" stupidity.

But is it really technology that's making people "stupid"? I don't think technology as such can be blamed. While it does seem that lots of computer use (as opposed to reading) can affect brain, personality and identity, in this context personally I wonder if the seemingly increasing abrogation of responsibility and refusal to think beyond rigid literal rules are partly due to information overload - there's too much you need to know about these days, it's too difficult to understand most of it, so the path of least resistance is just to stick your head in the sand, stick to reciting the rulebook, and not have to think about anything.

If modern society is to achieve a sensible balance between security and freedom / convenience, a lot more people will need to start putting on their thinking hats and taking their common sense pills!

Virtual Worlds: Serious Applications - free talk





I notice the Imperial College Internet Centre (ICIC) are hosting a free session Serious Applications of Virtual Worlds - ICIC Tuesday Talk on Tuesday 30 September 2008 from 4-6 pm.

From the blurb: "Dave Taylor, Programme Lead for the Medical Media and Design Laboratory (MMDL), will deliver a talk entitled "Serious Applications of Virtual Worlds" including a live tour of the SciLands (Science and Technology Continent) and Imperial College's new Medical School in Second Life. Dave will also give details of a virtual worlds competition that is planned for later this year... Second Health is an immersive hospital environment that can be visited in Second Life."

There are 30 tickets left as I write, if anyone interested wants to sign up.

In July 2008 the Internet Centre hosted an excellent day of seminars on Wealth of Networks 2008: digital economies & next generation internet (of which I managed to produce some audio recordings), including a very interesting and thought-provoking session on digital economics and the monetization of Web 2.0 so this session looks like it'll be well worth attending.

The human voice: Pavarobotti, singing styles etc





I recently watched the documentary The Voice about the science of the human voice, how it works and why it's so hard to replicate it - whether it's an artificial voice through machine synthesis of speech / singing, or in mimicking other people's voices (the programme also featured famed impressionist Rory Bremner, whose imitation of Tony Blair actually improved after a comparative analysis of their speech). It's a repeat, but I'd missed it when it was first broadcast.

You can watch The Voice free via the BBC iPlayer (more info on BBC iPlayer) until 8:29pm Friday 19 September 2008.

It was presented by Prof David Howard who has a chair in music technology at the University of York (I'd heard him speak before on the voice and vocal care etc, though he never did reply to my email asking about his supposedly freely available WinSingad voice analysis free software).

I absolutely loved the Pavarobotti (produced by Dr Ingo Titze and team), which you can hear singing Nessun Dorma on YouTube:



And here's another link I found from Stuttgart University of the Pavarobotti, rather less interestingly, singing the word "Fly" several times!

It was also fascinating to hear voice coach Christella Antoni, who has such deep physiological / anatomical knowledge and fine control over her own vocal apparatus that she can sing to order in many disparate styles. On the programme she sang in the styles of Katie Melua, Barbra Streisand, Ella Fitzgerald and Ethel Merman! Impressive.

(She appears in fact to specialise in speech and language therapy for male to female (MTF) transgender / transsexual individuals in London - I wonder if she'd be willing to coach non-trans people in singing, especially belt? If I could just learn to belt properly, I'd - well, with one or two other things - die happy. She seems to be a proponent of the Estill school though, which as I've said before isn't necessarily supported by all good singing teachers.)

Epigonion: hear ancient Greek harp sounds





The Astra Project have re-created what an epigonion might sound like.

No, the epigonion is not some kind of extinct hog, it's actually an ancient Greek stringed musical instrument which sounds like a harp and was apparently played up to the Middle Ages (see pictures of the epigonion).

Nor is the Astra Project about things astronomical - it: "aims to reconstruct the sound or timbre of ancient instruments (not existing anymore) using archaeological data as fragments from excavations, written descriptions, pictures...The technique used is the physical modeling synthesis, a complex digital audio rendering technique which allows modeling the time-domain physics of the instrument. In other words the basic idea is to recreate a model of the musical instrument and produce the sound by simulating its behavior as a mechanical system."

Click the arrow to play online, the text to download:
Listen to some Monteverdi as played on 4 simulated epigonions - and hear more examples.

What a fascinating project, I'd not come across it before.

Linux on your Windows desktop or laptop - Dell move; and refund for unused Windows?





It's an interesting indication of the growing popularity of the open source Linux operating system that Dell are now offering Ubuntu 8.04 (Hardy Heron) pre-installed on several of their systems to consumers in the United States, France, Germany, Spain, Canada, United Kingdom and many Latin American countries (like Mexico and Colombia) - initially on the XPS M1330N and Inspiron 1525N notebooks and the Inspiron 530N desktop computer, with XPS M1530n and Studio 15n to be added to the Linux lineup in August. (Via Heise Security.)

Heise noted that the Linux versions will be cheaper than the Windows version, if you compare like for like in terms of hardware spec.

But don't forget that even if you bought a computer, whether desktop or laptop, with Microsoft Windows preinstalled, if you installed Linux (of any flavour) and didn't use Windows, at least if you act quickly and return the Windows CDs you may be able to claim a refund from the retailer for the unused Windows software - at least, the courts in Italy and France have said so in relation to HP and Acer systems, and reportedly Dell in Germany had also agreed to give refunds. All, it seems, based on Microsoft's EULA (see my previous post). The same could be the case for other Microsoft software that's pre-provided.

I don't know if anyone has tried to get a refund in the UK, and whether they succeeded or not - it would be interesting to hear about it, if anyone knows? (This isn't legal advice etc, I've no idea if it would work in the UK, it just seems like it might be worth a try - obviously, take advice on your own position if you really need to!)

Computers & internet: affecting brain, personality, identity?





Is computer use shaping children's personalities in a new way? In a fascinating article from a recent New Scientist, neurophysiologist Baroness Susan Greenfield set out the thesis of her new book, which I plan to read: ID: The Quest for Identity in the 21st Century.

To summarise her ideas:
  1. The mammalian brain, including ours, is "plastic" - human neuronal circuits are malleable, sensitive, easily shaped by external influences and by one's activities (witness the famed research showing that memorising street navigation had enlarged the hippocampus of London's licensed black taxi cab drivers).

  2. She suggests the human mind isn't a mere abstraction, but is "the personalisation of the brain, a set of neuronal connections peculiar to each individual, driven in turn by that person's particular experience and interaction with the outside world".

  3. Of course, the outside world now includes technology. (She also discussed biotechnology etc but I'll skip over that here.)

  4. Might living effectively in 2 dimensions via a computer screen affect neuronal connectivity? (It's been estimated that western children spend about 6 hours a day in front of a computer screen currently.)

  5. More specifically, would "continued interaction with a fast-paced, sensory-laden, multimedia environment predispose a brain to shorter attention spans?" Is it just coincidence that prescriptions of methylphenidate (Ritalin) for attention deficit hyperactivity disorder (ADHD) have trebled these last 10 years?

  6. She also suggests that "the strongly visual, literal world of the screen" could affect our ability to develop the imagination and form the kind of abstract concepts that have hitherto come from first hearing stories, then reading oneself. "Will future generations prefer the here-and-now, opting for a strongly sensory experience over a more personalised cognitive narrative? When you play a computer game to rescue the princess, it is the experience that counts: you don't care about the feelings or thoughts of the heroine. When you read a book, the princess's welfare and fate is the whole point."

  7. Following on from that, could "here-and-now, fast-paced sensory experiences" change how future generations see themselves and construct their identity? Could they choose to stay in a "more infantile world of passive reactivity to sensations", perhaps even "a world where there is no personal narrative at all, no meaning, no context, just the experience of the thrill of the moment?"

  8. In her book ID: The Quest for Identity in the 21st Century, she suggests 4 scenarios for identity:
    1. "Nobody" - an abrogation of the sense of self, hedonism, blowing our minds, letting ourselves go. She posits "that the newer technologies may predispose future generations to seek just this sort of condition."
    2. "Someone" - the persona that prospers under liberal western consumerism.
    3. "Anyone" - the persona of the collective identity in fundamentalist or communist cultures.
    4. "Eureka" - "where the experience of creativity enables you to feel both fulfilled and to have a sense of individual identity (none of the first 3 scenarios seems satisfactory when taken alone). But she notes that some might object that the Eureka scenario could produce "a dysfunctional society of egocentric, eccentric individuals".

  9. She theorises that newer technologies may predispose future generations to seek the "Nobody" scenario: "Twenty-first-century technology is giving us, for the first time and en masse, more time each day and the chance to live to an active old age, and this brings with it greater options for creating or experiencing a dystopia or a utopia than at any previous time."

  10. While the dystopia is a risk, she also suggests: "Perhaps one answer would be to promote a mixed portfolio in which future generations flip from "let yourself go" (Nobody), to selfless, collective working (Anyone), to an occasional sense of personalised achievement (Someone), based not on superiority of status or possessions but on that internal glow that comes with insight and creativity (Eureka). Now that might even be fun."
I think what she says makes a lot of sense. Much of it also applies to the TV generation too, of course, not just the gaming / computer kids. I had the chance to hear her on just these issues at a session at the Dana Centre some time ago (a proper event, for a change, where they actually let the expert say what she had to say, followed by questions from the floor - instead of making attendees scull around listening to opinionated know-nothings spout off in unfacilitated free for alls or trying desperately to catch the experts in time slots that were too short because of the time-wasting involved in shunting people around different rooms in lieu of a proper panel with Q&A in one large room. /rant about Dana Centre's "interactive" approach).

Anyway, back on topic, I really identify with the "Eureka" scenario - but in a much broader sense. It made me think about how much I live for those Eureka moments, to exaggerate only slightly. I've always had an enquiring mind, always wanted to know, I love learning new things, and that high when I suddenly get something, finally understand something, is hard to match - I suspect the buzz is addictive, in a way. (And no, I'm not trying to find excuses for my eccentricity!)

I also think she has a point about kids being unconsciously "conditioned" into passive, experiential, me me me consumption. I use computers and the internet as a participatory medium more than anything - for me it's very "lean forward". I do my share of leaning back, but that's usually in front of the TV, or with a book or magazine. However, I was brought up more with print than computers (though I did watch TV), so maybe that's just a reflection of how my brain's been shaped by my own childhood experiences.

What do you think, do you feel she has a point, or do you disagree?

The joy of hard drives: why buy a DVR or PVR, & ditch the VCR





Surprisingly few people I know have digital video recorders or DVRs (also known as personal video recorders or PVRs), geeks and gadget fans excepted. Why haven't PVRs caught on more in the UK?

Here's why I extol the virtues of hard disk PVRs, by way of comparison with the bad ol' days of VCRs (video cassette recorders). And also why I think hard drive DVRs beat DVD ones hands down. Feel free to use this to persuade any remaining doubters in your family!

Sky Plus (Sky+) is the best known PVR, but you don't have to be a Sky subscriber to get a PVR. If you watch TV more than minimally, don't replace your videocassette recorder with another VCR or even a VCR/ DVD/ Freeview combo - do yourself a favour and get a DVR (ideally with two Freeview tuners, even better with a hard drive). They cost about the same, or even less.

I've had two Panasonic DVRs, then two Topfield Freeview PVRs (by a Korean company - I really like the Topfield, especially the ability to add features via mini-programs called TAPs). This one little gizmo has transformed my life - or at least my TV viewing.

Here are what I consider the main pros and cons of hard drive PVRs / DVRs.

Advantages of hard drive DVRs

1. Quality

VCR: recordings on tape aren't top quality, and if you keep watching a favourite recording over and over (no, I don't mean that kind of recording, though some well might), the quality will get worse and worse as the tape wears out. Or breaks.

DVR: digital quality reproduction, every time.

2. Convenience, flexibility & timesaving in watching recordings

To me this is the biggest selling point of hard drive PVRs.

VCR: something's started recording. Drat, I can't watch another videotape cos, well, there's tape in there it's recording on, innit. Can't even start watching this recording till it's finished that recording.

PVR: something's recording. I can record something else at the same time (if I have a more than single tuner DVR). I can watch another previously recorded programme while it's recording. I can even start watching the current recording from its beginning, while its ending is still being broadcast and recorded, how cool is that? Can't do that with DVD recorders, nope (except DVD-RAM ones which let you watch something previously recorded on the same DVD that it's recording on to).

Or how about this -

VCR: want to watch recording X? Got to find it first. Hmmm, which tape is it on, again? Rummage, much mess (or more mess, in my case). OK, found it. I think (what does that scribble say again?). Nope, read that scrawl wrong, try this one instead. OK, got it. Cue fast forward, rewind, back and forth to find the right spot to start from. Who knows how much later.

DVR: want to watch recording X? Call up the list of recordings with one button press, it's automatically saved the titles of all the recorded programmes. Scroll or page up and down till you find the one I want, then select it. Fast forward and rewind very fast (2x, 6x etc speeds possible), till I find it.

And this -

VCR: got to stop watching and do something else. Must jot down how far along the cassette this spot is so I can find it again. I could just leave it at the same spot, of course, but if I want to watch something else on the same tape in the meantime, I'd have to hunt for the spot again.

PVR: got to stop watching and do something else. Right, I'll just add a marker/bookmark at this spot (I can add several to the same recording), then jump quickly to the right place next time I select that recording. Anyway, the Toppy remembers the last place I got to and if I stop, go watch another recording, turn it off, turn it back on and pick a recording again, it starts from where I left off.

3. Save space and (again) time

VCR: shelves bursting with videocassettes, errr what's on which video tape? Got to find one that's empty or has enough space for the next recording, ummm now how many minutes is left on this one? Not enough, got to find another. OK. Lots of fun with forward and rewind to find the right spot to tape from...

DVR
: just set it to record. As long as there's enough space left on the hard drive (usually there will be), that's it, it automatically finds a spot and records. No cassette or disk swapping or shuffling! (Though with DVD PVRs you still have to find storage space for the DVDs, and then find a DVD with enough blank space on it).

3. Programming recordings

VCR: so it's not too bad with Videoplus. But you may still have to set padding manually (to start the recording a bit earlier than the scheduled time and end it some minutes later than the scheduled finish time, in case of you miss the ending or indeed beginning due to last minute delayed starts, schedule changes etc). Setting channel, date, start and end times manually is a big pain. And if it's recording when you think "Oh I must remember to program X", forget it, multi-tasking is not the VCR's forte, you'll have to wait till it finishes recording before you can program something new (or edit an existing thing).

DVR: ah the beauty of EPGs! (electronic programme guides). 2 weeks of programme listings automatically downloaded over the air by the PVR. Call up the TV guide with one button press, pick your programme from the TV schedules shown, hit Record, and that's it. Simple to make that a daily or weekly recording too. Some software like MyStuff for the Topfield will even spot if a movie carries on after a news break, and prompt you to record the second half too. I've missed the ending of so many films on ITV especially, because I didn't notice to program the 2nd half too. No more of that!

If you want to program something else while it's recording, no problem either. You can even edit an existing item while it's recording.

5. Fave programmes and automatic searches

VCR: set a repeat recording for the same time each day or week. And pray they don't change the advertised time, as TV stations sometimes arbitrarily do with little or no warning. Usually just so viewers can miss the ending.

PVR:
with the Toppy at least, via add-on software downloads like MyStuff you can find a program in the EPG which you want to record, or that you've already recorded in your archive, then hit one button, and it will automatically record it each time that show is on, whatever time it's on. With the ability to finetune those automatic recordings by channel, day etc (so to avoid repeats you set it only record the programme when it's on channel X but not channel Y, or shown in the evenings but not if shown in the morning, etc - and any combo).

Desperate not to miss a series or movie that's going to air in a couple months? Even if it's too far in the future to show up in the 2-week EPG, you can add a search for it to record it automatically as and when it starts being broadcast - on a Toppy, anyway.

6. Pausing live TV

VCR: you're watching live TV (not a recording) and the phone rings, doorbell goes or food boils over, etc. You have to see to whatever it is, and then you've missed a whole chunk of what you were viewing.

DVR:
just hit Pause, go do your thang, and when you're free again (as long as it's not more than about half an hour later, usually), hit Play and carry on from exactly when you left ott. Now this is a handy feature, but when Tivo DVR came to the UK this was about the only benefit they focused their ad campaign on. Big mistake. They should have sung the advantages of nos. 1 and 2, which are the main features I love. I believe that Tivo bombed in the UK, although they still survive in the US, because they just didn't get across the right message (as to which, incidentally, this video on how to do DIY user research / testing may be instructive).

7. Spur of the moment recording

VCR: watching something, think oooh this is good, wish I'd taped it for the kid / other half / myself. Well, tough luck matey, you shoulda programmed it in advance shouldn't ya?

DVR: no problem. You can even "rewind" live TV (up to about 30 minutes back, on the Toppy anyway - other PVRs' "buffer" may differ) to start recording the whole programme from an earlier point, onwards, so you record the start of the show too.

The downside? Saving to DVD

Lots of pros, but one con to note. A pure hard drive-only PVR won't let you archive recordings to DVD easily, though one that's combined with a DVD recorder would. A hard drive PVR with twin Freeview tuners and DVD player/recorder would be ideal, and one day I'll get one.

The Panny I own had a DVD recorder, but it only had one tuner, and in a later model, the Panasonic DMR E100H, the sods ruined a perfectly good (indeed very good) user interface, so I won't risk buying Panasonic again anymore, myself.

Still, it's not impossible to save recordings even with a hard drive-only DVR. With my Toppy I can transfer a recorded .rec file from Toppy to PC or Mac (or rather, an additional huge hard drive connected to PC, as the files are pretty big), then burn them to DVD on my computer for later viewing.

That's another advantage of the Toppy - it has a huge, knowledgeable and helpful user community at Toppy.org.uk (and in other countries), who do things like provide instructions on how to archive recordings, and write free little programs (called TAPs) to fix bugs or annoyances or to enhance the Toppy. I didn't write about them in my main list of pros as these benefits are I suspect specific to the Toppy rather than for PVRs generally. But I'm sure some other brands have decent users communities too.

Don't get me wrong, I've had my share of problems with the Toppy - but they haven't put me off, and other Toppy owners are really helpful in getting them fixed, much faster than a support line would (though I've never had to try Toppy direct).

The Topfield also has slot for Top-Up TV card, if you want the option of subscribing for that later. I never did it - now that we have BBC iPlayer, and I can also record all my fave programs so easily from Freeview to Toppy, I've my work cut out just watching those, never mind stuff on pay TV channels too! (I'm not desperate to be among the first to watch the latest trendiest thing ASAP, I'm happy to wait most of the time.)

Anyway, this post isn't aimed at comparing DVRs or advising on which to buy, as I've only tried the 2 brands (2 models of each, mind). If any other brands would care to invite me to try and review their products, my contact details are in the sidebar.

Meanwhile, as you can tell, my personal preference is for the Toppy, rather than Panasonic. If you decide to go for a Topfield be warned that a new model, the 5810, is out, so you might want to get that model, or else pick up the older 5800 cheaper (some people prefer the older model however - check out the differences between the Topfield 5800 and the 5810).

Buying tips

I'll just end with a few buying tips:
  1. What about Blu-Ray? Good question. Increasingly you can get BluRay recorders (e.g. the Sony BDP-S1E was the first European Blu-ray disc player) especially now it's won the format war against HD-DVD. 25 or 50 GB storage on a single Blu-Ray disc is good, of course, but personally being lazy about swapping discs I prefer to have 250GB on a hard drive, or even 500GB now. Plus, I'm waiting for the cost of Blu Ray to come down a lot more. Your choice...

  2. If you get a PVR, ideally get one with two Freeview tuners, for more flexibility. Heck, 3 tuners if there are any! Of course this saves you from buying a separate Freeview set top box too, if you've not got digital terrestrial TV yet.

  3. I prefer hard drive PVRs myself, as mentioned I'm lazy about swapping discs, but it's your choice - if you can find a combo hard drive and DVD recorder at a decent price, consider it (but don't forget DVD recorders may record to different DVD formats e.g. DVD-RAM, DVD+R etc. I was a DVD-RAM fan because of no. 2 above, but blank DVD-RAMs were more expensive and might not play in other players, and DVD-RAM seems now to be pretty much dead. DVD-R seems the most compatible.)

  4. If you get a hard drive DVR, get one with the biggest hard drive you can afford. If there's space you'll fill it up, believe me! I'm constantly trying delete stuff from my 250 GB PVR.

  5. If you want Top-Up TV then obviously get one with an appropriate card slot.

  6. Size matters! I'm virtually out of room on my TV stand and STBs (set-top boxes) can accumulate... Thin is good.

  7. If you're wondering about how to hook it all up, see my guide on how to connect audiovisual (AV) devices.

  8. Consider getting a universal remote control for extra convenience.

  9. Converting from VCRs - there are lots of tools and howtos now to help you digitise your old VHS videocassette tape collection i.e. convert them to digital files to burn to DVD or store on hard drive etc; you can even buy dedicated gadgets to do it for you. I won't go into that here, just see e.g. this Google search.
And talking of conversions, I hope that's enough to convert remaining doubters to the joys of digital PVRs, or help you to convert others in your family who've been against it!
