An enforced Easter break and general thoughts on Phones Show scheduling

Dear Phones Show and PSC viewers and listeners....(!)

Just a small status update regarding the shows.

PSC records on a Sunday evening and thus clashes with Easter Sunday - I think Ted and I did a show last year anyway, but this year I'll be knee-deep in family, so we're going to miss a week. I'm sure you'll have your own family time and won't miss us too much?

The main Phones Show has been hit a little by several general factors, worth noting:

• a continued decline in the number of people financially supporting the show, meaning that I've had to take on extra writing work to make ends meet. 
• the critically poor health of one of my parents, a factor which may well play a bigger role as the year goes on. This factor in particular has to take absolute priority, as I'm sure you can sympathise?
• a huge number of other online video shows, often with far bigger financial resources and offering higher production values. When I started The Phones Show (as 'The Smartphones Show') in 2006, I was just about the ONLY person in the world reviewing phones in video form. Heck, even YouTube itself hadn't got going properly then. Eight years later, it's so much easier for anyone to review phones and produce video content that there are now tens of thousands of competitors.

In addition, specific to the next show, 225, in which I should be wrapping up my Galaxy S5 review by now, Samsung has essentially shafted all online retailers (e.g. Clove here), and I've been unable to get a review device yet. Immensely frustrating all round. In view of this, Phones Show 225 will be delayed by a week or two - I do have a backup review device source, hopefully delivering something mid next week.

The general factors listed above have caused me to have a rethink of the scheduling generally. I don't want to push out sub-standard shows just for the sake of it. And I also don't want to give myself a nervous breakdown trying to keep up a particular bi-weekly schedule just for the sake of it.

So, in future, Phones Shows will come out when they err.... come out! In busy times, this might be more often than once a fortnight, at other times, the gap will be longer. PSC will carry on weekly, of course.

I've asked several times whether those people who do donate, do so because of the video show or the weekly audio podcast - and the balance has been tipping in favour of the latter in recent years. I'm therefore hoping that my decision to be a bit more relaxed over Phones Show scheduling won't affect donations too much. As ever, donating to the 'Virtual Pint of Beer' club is entirely voluntary - I, and Ted, aim to provide you with quality listening (and viewing) and my hope is that enough people will recognise this and carry on subscribing.

Finally, Happy Easter and best wishes from a very sunny UK!

Pop-out batteries save the day from human error!

I've ranted before about the potential perils of sealed batteries on phones, something of a worrying trend in mobile design. Yes, I know designs can be simpler and more streamlined, but it really hurts the long term flexibility of the device.

Not least because there's precious little way back from human error. In this case, me. My error.

I charge my smartphone, like most people, with a microUSB mains charger beside my bed. Each night I plug the phone in and settle in for a good sleep, confident that my phone will wake me up at 7am in the morning, fully charged and with my morning alarm sounds.

At some point yesterday, I needed to plug something else in and so the phone's power adapter got unplugged. You can probably guess the rest, but...

As I drifted off to sleep I noticed that the usual Android 4.3 DayDream clock face (usually on during charging) wasn't showing. Yes, it was my clock during the night, but hey, I was tired and couldn't care too much. Zzzzzzz.....

By sheer chance I woke up at 6.30 anyway and pressed 'play' on my headphones, hoping that my currently playing podcast would spark back into action. Nothing.

"That's odd", I thought, so I reached out to the phone itself and pressed the screen wake button. Nothing, just a faint flash of red LED at the top of the device. Realisation dawned. The power adapter. My phone hadn't been charging at all during the night and it was now out of power.

Completely out of power. So far gone that plugging in the charger again (at both ends!!) did nothing. Just a placeholder icon on the screen. No LEDs, no sign of life, nothing. I left the charger plugged in for 10 minutes and still nothing. Clearly the battery had been forced into such a state of distress that it was now sulking.

With a sealed design, my options now would have been strictly limited. I guess I'd have played with various button combinations to achieve a reset, hoping to spark the electronics into some kind of charging action. If I was lucky. Plus, even if that worked, I'd have to go around all morning with a microUSB portable charger plugged in, via a wire, at the very least.

A nightmare scenario.

Except that the phone in question was a Samsung Galaxy Note II and had a replaceable battery (as shown above). So I strolled into my cupboard and pulled out my spare ANKER battery. I ripped the back off the Note II and stuck in the spare. The phone booted up fine and showed 62% left on the cell (not bad after several months in storage), so I was good to go for most of the day, at least.

I put the discharged cell into my mains Note II battery charger (only a few quid on eBay) and the LED glowed red/purple, indicating that it was charging happily - phew! I'd be able to swap back to my main battery (which had the add-on Qi charging coils attached) this evening.

So.... having a replaceable battery saved the day - literally. I was able to head out and about entirely as normal, with no dangling wires or power worries.

Add in the other benefits of going replaceable, like the flexibility to add in much higher capacity batteries, and you can see why I remain a fan - and an opponent of strictly sealed designs.

Musings on smart watch face shapes and areas

I was listening to a Gavin and Dave's podcast this week and they were chatting about smart watches - and something they said didn't sound quite right. Now, this isn't a criticism of their thinking per se, but it did get me thinking.

They were responding to the announcement of Android Wear, a 'smart watch' OS and SDK and with some prototype devices shown off to model the interface. One of which had a traditional rectangular screen and one of which (the Motorola 360) had a circular display. The contention on the podcast was that the circular display was, by definition, less efficient in terms of space usage, because you 'lost all the corners', paraphrasing their argument.

However, this ignores the fact that the circle is the most efficient shape, in terms of geometry. In other words, take a circle and square of the same area and look at the sizes involved. To approximate scale, and mocked up in smart watch UI style, which of the displays below looks bigger?

The answer is that they look the same size - which they are, in terms of area - that was the point - yet the linear dimensions of the circle are about 12% larger. In other words, a circular design could either be slightly (physically) larger and yet not look larger.

Whether the different shapes are more or less efficient in terms of displaying content depends rather on what the content is, of course. In the diagram above, there are slightly more characters displayed in the circular version - again because a circle is more efficient by definition. And helped by the freeform nature of text, of course. While the tree graphic is wider in the circle version, but has detail in the top corners in the square version, so the swings and roundabouts for images.

I'd also argue that a circular watch face is more natural/organic - and certainly more traditional and acceptable, all factors that may help designs like the Motorola 360 be a success.

Against the circle concept are technical factors - display electronics and software drivers for non-rectangular LED arrays, applications that have to be totally re-written (or even re-imagined) for a circular interface, and so on. Circles may be physically more efficient, but there's a reason computer displays are always rectangular - computers tend to think in terms of straight lines of equal length!

Just food for thought!

Automator - just one MORE reason why I use an Apple Mac....

Mac vs PC debates have raged through the ages, of course. And I can't hope to summarise the pros and cons of each in a simple blog post here. But I did want to shout about something that delighted me in recent months about my Mac and that's discovering how to use the Automator utility.

Here's the use case. I had a bunch of photos and screenshots, all of which I wanted resized to 600 pixels wide, for inclusion in a Wordpress blog post elsewhere. Painstakingly, I opened each in Seashore (v0.1.9, the older one, is the best to use, IMHO) and resampled down, then saved. There must be a better way, I thought.

I started browsing through the Mac App Store and did find a few batch resizers, but they all cost money and seemed too complicated. I wonder.... I remembered seeing Automator a few times in my app list on the Mac, so I gave it a whirl:

1. Start Automator
2. Click on 'Application'
3. Click on 'Photos'
4. Drag the 'Scale images' action to the application pane (you'll be prompted to add a 'copy' action, so as not to replace the originals - this is a good idea for most people)
5. Change the scale value as needed
6. Use 'File/Save' to name and save the application somewhere sensible (e.g. the Applications folder)
7. Drag this application onto the Mac's dock

And that's it. Took all of 45 seconds. Now, when I want a batch of images scaled down to 600 pixels wide, I just drag them all en masse from Finder to the icon on the dock. A few seconds later, the OS has done its work and my images are ready.

In fact, it proved so easy that I made a second one, for resizing to 800 pixels (for the All About sites). 

Then, a month later, I had a similar problem. I was creating (and downloading) a lot of images in PNG format (from screenshots, usually) but they were all way too big in terms of byte size. What I wanted was to convert them all on an ad-hoc basis to JPG. Again... I wonder....?

Automator to the rescue again, this time using the 'Change type' action from the 'Photos' section. Again, I now just drag any PNGs onto this icon on my Mac dock and bingo, they're all JPGs.*

This facility to just 'create' utilities with zero programming knowledge, and all built into the OS, is just tremendous - and, as something of a beginner, I feel as though I've only just scratched the surface of Automator here! See here for a list of 10 top uses in more detail.

* in fact, I also often then drag these files into JPEGmini, also a useful tool!

The Rolls Royce of smartphone belt cases: PDair

In a mad world where I change my smartphone almost weekly, as part of the review process, one thing has remained constant: the case I carry said smartphone in. You see, and I realise I run a huge risk of being declared uncool here, I'm a passionate believer in belt cases. As slimline and unobtrusive as possible, of course, but a belt case nonetheless.

Cynics will point to the fact that I'm already married and thus don't need to attract the opposite sex in quite the same way as younger folk might need to, and I accept that there's a certain 'geek' impression created by a belt case - but then aren't geeks supposed to be cool now too? Aren't we geeks supposed to inherit the earth, etc.?

The advantage of a belt case are:

• you don't have to keep standing up and taking a phone out of your trouser pocket - the case is accessible in any position
• you can't easily leave your phone behind somewhere - less lost phones
• there's greater protection than if a phone is in your pocket - you can't sit on it or stress it by bending the wrong way

Against these 'pros' there's the con of geekiness, as mentioned above (not helped by the big key/penknife ring in this case!!), plus a possible security risk in that a thief might be able to withdraw the phone - I address the latter by swinging the case around to my tummy in crowds, so that it's far less accessible to third parties.

All of this is building up to a recommendation. If you want a belt case, get the best. PDair's range of genuine leather slip cases with really, really tough (and yet slimline) belt clips, has been my mainstay now for many years. Here are just four of the variations I've used (I have half a dozen more scattered around or lent out):

(For the sake of disclosure, I've bought about half of the 10 or so variants that I own, and the remaining half have been for review purposes.)

Every other vertical format belt clip case I've tried has been too cheap (falls apart), has a top flap (gets in the way) or (my pet hate) has a belt clip 'swivel' that makes the case stand out a mile - looking terrible and also ending up very fragile.

The latest in the series here is for the Samsung Galaxy Note 3 and Note 2, but of course it's wide enough to take just about any other modern large screened smartphone too, so I don't have to keep swapping belt cases when I swap phones.

Build quality, as ever, is tremendous and I can't recommend this particular design highly enough. You can browse PDair's vertical belt cases cases here - and then follow your nose for where to buy (e.g. on Amazon here).

Mini-review: JPEGmini (for PC and Mac)

Sometimes a product just works like magic. This is just one such....

The problem is this, you see - JPGs. Photos, screenshots, scans, just about anything graphic uses the JPG compressed image format these days. As a journalist I use a lot of JPGs and there's always this terrific push-pull going on between quality and byte size.

Not many people realise that a JPG can be any size. it's essentially a lossy approximation of your original image (e.g. from a camera or screenshot or scan), but intelligently degraded such that you don't notice any difference.

Take a 5MP photo from your phone. Uncompressed, you'd be looking at 20MB or so, but the device probably spits it out at 2MB or so, applying a particular JPG 'quality' (usually about 85% or so) - your eyes can't tell the difference most of the time, but look down at the pixel level and you'll see artefacts.

So the photo could be represented by a 5MB JPG with almost perfect 'quality' and almost no artefacts, or a 100KB image of the same physical size but terrible approximations and degradations. Where the 'quality' is set depends on the settings in your camera or software utility or scanner or whatever.

My problem is that I often want to use images that are very high quality, just in case I want to print them or crop them later - at which point I might be very miffed if I found that, deep down, they all had artefacts. So I leave the quality settings quite high in my image editors.

Yet, when I use photos online, byte size is much more important than absolute quality. So, for web page use, I'd like a lower JPG quality - yet it's a pain having to keep switching settings. And that's not counting the number of apps and devices for which JPG quality is set and unchangeable.

One option is to re-save each JPG in a utility, but I hadn't found anything useable or convenient until I came across JPEGmini, here shown running after processing some screenshot JPGs on my Mac:

Essentially, if I have a batch of JPGs (usually photos or screenshots in my case) that are all intended for inclusion in an article or post, I drag them all into JPEGmini before uploading. Each image is cleverly analysed and then optimised to the point where it has the minimum size before any visual degradation becomes apparent.

So, for example, I'd have a folder of 30 screenshots and a photo. Total original byte size would be about 8MB, meaning that anyone reading the article would essentially have to download all of these in order to be able to view the page in full. JPEGmini typically optimises these same JPGs down to about 4MB all-in, effectively halving the load on the web server and halving the download time for each user.

I do keep trying to catch JPEGmini out and looking for a photo it has optimised which looks 'worse' than the original, to no avail so far. Its secret is not to try to optimise the file size too much. So you really do get byte savings without any visual impact.

My only gripe with JPEGmini, on the Mac at least, is that you can't drop JPGs directly onto its dock icon - you have to have the app open and then drag into its window. Apparently dock integration is on the to-do list for the developer, so we'll see....

You can try one of your own JPGs online here and then give the utility a try - I can't recommend it highly enough for this sort of targeted JPG byte size reduction.

Spring/summer PSC meet up!

By popular demand, for anyone local to Berkshire, UK, I'm hosting another Phones Show Chat pub meet-up for smartphone enthusiasts on Wednesday 26th June 2013, from 7pm until whenever we call it a night. The venue is the usual The Lands End Pub, Park Lane, Charvil , Twyford, RG10 0UE. See below for a map. The Lands End is perfect for meets because there's no piped music, plenty of space, good food and drink, and plenty of parking. Oh, and it's also my local! 8-)

Use your sat nav to get to the general area. You can approach The Lands End from the East, but you have to go through the ford - not recommended if there's been a lot of rain. Usually about a foot or so deep, so 4x4's only! Approach via the arrowed directions if possible.

The idea is to swap phone tech stories, try out other people's favourite devices, down some decent beer and (maybe) do a few short pieces to camera for the show. If it turns out well, you might be a star(!) I'll bring along a dozen smartphones, plus prizes to give away.

If you want to come along, just confirm by emailing me at slitchfield@gmail.com with the subject line "June Meet". Thanks!

As long as even half a dozen people make it, the event's a goer. Hopefully we'll have quite a few more than that!

Batteries again. And cards. And backs. Samsung's way is the flexible way - more power to the S4

I've ranted in the past about the implicit dangers of 'sealed' batteries (as on the iPhones, HTC One range, and so on). In summary, batteries degrade over time and, a year down the road, do you really want to be struggling with a smartphone whose battery is at 70% original capacity and now won't last you beyond tea time? I thought not.

Having a replaceable battery means that you calmly source a new cell - or perhaps even upgrade, as I did with the Samsung Galaxy S III, to a larger capacity battery. The choice is yours when you've got access to this most vital component. Plus, of course, there's the road warrior option to own a spare battery and keep it in a pocket for evening power emergencies.

Such flexibility is lost with sealed devices. In fact, there's more at stake than just battery power - microSD expansion is something else which keeps getting forgotten by trendy manufacturers like Apple, HTC and LG. Your music collection won't fit on your phone? No room for those videos? Darn it, your maps won't fit on either. Sorry, you're out of luck.

Unless your phone has microSD expansion, in which case you just upgrade your card from a 16GB to a 32GB or even a 64GB, for no more than a few tens of pounds or dollars. Job done.

Samsung's sales have been setting world records over the last year, and the company's huge marketing push has been given most of the credit - the ads have ensured that everyone now knows the 'Galaxy' brand. I contend, though, that there's an intrinsic characteristic of Samsung smartphones that's not often spoken of in tech circles.

Samsung are the only major manufacturer* to stick, exclusively, to a flexible design, wherein the back of each phone comes off and you can change the battery or microSD at will. Heck, you can even change the back cover itself, for one of a different colour, or with integral leather flip, or one that's supersized and comes with a battery of much higher capacity.

      * Nokia comes close, with only a handful of 'sealed' designs to blot its copybook...

(image credits)

It all comes down to choice and flexibility, both of which are things that end users love.  This is at least one major reason why many people love Samsung Galaxy products, not TouchWiz or Samsung's bloatware (which I tend to work around as much as possible, see my video tutorial).

Yes, you can get cases and chargers for iPhones and HTC One devices. Whoopee Doo. You can already get an eye-watering number of Samsung Galaxy S4 accessories - and the S4 isn't even available yet. If the Galaxy S III is anything to go by, there will be replacement backs, batteries, wireless charging modifications, and much more.

I accept that the iPhone is prettier, the HTC One is better built and the Nexus 4 runs a purer version of Android. But for the end user who simply wants the most powerful, most flexible, most future proof smartphone, then the Galaxy S III - and now S4 - make the most sense, I contend.

Never heard of RHA headphones? Neither had I...

Please excuse the brevity of this post, but there's a very good reason. The kind folks at RHA, based in Scotland, sent me over a set of their MA350 in-ear headphones to review and, after some initial testing and photography, I foolishly lent them to my wife to 'try'. Who liked them a lot and lent them to a relative to 'try'. And I haven't been able to get them back since.

From which I can draw two conclusions:

1. Never lend out stuff you really want back
2. The RHA headphones made a very positive impression with each of us

Hey ho. I was very impressed by the build quality, from the aluminium speaker housing 'cones' to the anti-tangle material coating on the cable, while audio was clear and distortion free. If I had to be picky, it would be that there wasn't as much bass as with the same music tracks on my Monster in-ear headphones, though in fairness the RHA MA350 are only a third the price.

As a replacement for a generic 3-pole set of in-ear headphones, it's hard to beat the RHA set at the price, so they come with my recommendation. Now, please, I want them back....

Switch off fortnight? What? NOW? Craziness...

So which blithering idiot scheduled 'Switch off fortnight' in the UK for two weeks in the late Autumn? When it's cold enough that every device left 'on' actually contributes to heating our buildings and thus means less work for the heating system to do?

In other words, switching stuff off at this time of year has almost no 'net' effect whatsoever.....

'Switch off fortnight' needs to have happened in the SUMMER term, when dramatic overall savings could have been made.

As a physicist, I sometimes despair..... 8-)
