Microsoft should have made a separate Windows for tablets say critics – but it did

2 Comments

David Pogue at the New York Times expresses a common view in his take on Windows 8.1:

The more you work with Windows 8, the more screamingly obvious the solution becomes: Split it up. Offer regular Windows on regular computers, offer TileWorld on tablets. That way, everyone has to learn only one operating system, and each operating system is suited to its task.

Simple, eh? One of several flaws in this argument though is that Microsoft did exactly that.

What is Windows RT? It is a Windows tablet OS where only Windows Store apps can be installed. Admittedly the presence of the desktop in Windows RT, in order to run Office and to access settings that would otherwise be unavailable, is a sign that Windows RT is not quite done; but you can ignore it if you want. If you are looking for Windows 8 for tablets only, here it is.

Did the market love Windows RT? No, on the contrary, Microsoft had to write down $900 million on excess Surface RT inventory and OEM partners have pretty much abandoned it, leaving Surface 2, which also runs RT, alone in the market.

What was wrong with Windows RT? While you can identify missteps in naming and marketing, the fundamental reason is the weak app ecosystem, which limits what you can do.

There is no reason to think that some other variant of Windows RT – for example, one without a desktop at all, or renamed “Surface OS” – would have fared any better. It would probably have been a bigger disaster, lacking even the benefit of Microsoft Office.

Personally I like Windows RT and I think it is strategically important, though rumours suggest that it will be absorbed into a future Windows Phone OS:

Right now, Microsoft has two ARM-based Windows operating systems: The Windows Phone OS and the Windows RT OS. The thinking is these will be one by Spring 2015. Because it tends to be easier to take a “smaller” OS and add to it than to take a larger one and remove features from it, it’s likely that the Windows Phone OS is the one on top of which the new operating systems group will build.

The reasoning, incidentally, does not altogether make sense, though I do not doubt Mary Jo Foley’s reporting. Windows Phone itself is based on a cut-down version of a larger operating system, with the Windows 7 range built on Windows CE and the Windows 8 range built on the full Windows NT kernel. What we will get, I suspect, is unification of the app platform in Windows Phone and Windows 8, and the question will be what happens to the desktop and ability to run full Office in this ARM Windows vNext.

Aside: of all the gadgets I carry around, it is Surface RT that draws the most approving comment from non-technical friends, thanks to its small size, excellent screen, long battery life, and ability to run Word and Excel as well as tablet apps. Of course it is too expensive and too slow, in its first release, and while Surface 2 may fix performance, it will not fix the premium price.

7 types of Windows 8 users and non-users

7 Comments

When I was in Seattle earlier this month I visited the Microsoft Store in Bellevue. I nearly bought a Nokia Lumia 1020, but also observed an enthusiastic salesperson showing off Surface 2 (a pre-launch demo unit) to an older customer. She watched patiently while he showed how it handled pictures, SkyDrive, Office, Email, Facebook and more. At the end she said. “I don’t need any of that. Show me your cheapest laptop.”

image

Yes, it’s tough for Microsoft. The incident got me thinking about computer users today and whether or not they are in the market for Windows 8 (or the forthcoming Windows 8.1).

Here is a light-hearted at some categories of users. And yes, I think I have met all of them. For those that are saying no, what would change their minds?

1. The Apple fan.

Switched to Mac from Windows XP around 2007. Has Mac, iPhone, iPad. So much easier, no anti-virus nags, boots quicker, less annoying, always works smoothly. Occasionally runs a Windows app on Parallels but nothing non-nuclear would persuade them to switch back.

Buying Windows 8? No.

2. The Enterprise admin.

In latter stages of migration from Windows XP to Windows 7. Still a few XP machines running awkward apps or run by awkward people. Last holdouts should be gone by year end. Job done, won’t even think about another migration for 3-5 years. Next focus is on BYOD (Bring your own device); will be mostly iPhones and iPads with the occasional Android or Windows 8 tablet.

Buying Windows 8? Mostly no.

3. The older Windows user

Son thinks a Mac would be better, but Windows works fine, is well understood, and does all that is needed. No desire to upgrade but when PC conks out will look for the most familiar looking machine at a good price. Would prefer Windows 7 but may be forced into Windows 8 if those are the only machines on offer.

Buying Windows 8? Maybe reluctantly.

4. The PC guy

This is the guy who understands PCs back to front. Never saw the point of Macs, overpriced, fewer apps, and little different in functionality. First thing to do with a new PC is either spend 3 hours removing all the crapware, or reinstall Windows from scratch. The Windows 8 user interface took some adjustment at first but fine with it now, likes the slightly better performance, and even uses a few Metro apps on the Surface Pro tablet.

Buying Windows 8? Yes, best Windows yet.

5. The tablet family

Used to update the family PC every few years, but mum got an iPad, son got an Android tablet, then dad went Android too, and now they spend so much time doing email, games, web browsing, YouTube, Facebook and BBC iPlayer on the tablets that the PC gets little use. It’s still handy for household accounts but it won’t be replaced unless it breaks.

Buying Windows 8? Not soon, and maybe not ever.

6. The tried it once never again person

It was embarrassing. Used Windows for years, then a friend brought over a Windows 8 laptop. Clicked on desktop, but with no Start button how do you run anything? Clicked around, right-clicked, pressed ESC, pressed Ctrl-Alt-Del, but nothing doing. Friend was laughing. Now the sight of Windows 8 evokes a chill shudder. Never, just never.

Buying Windows 8? No way.

7. The “Make it like 7” person

Windows 8? No problem, it’s just like 7 really. Installed Start8, got the Start menu back, set it to boot to desktop, set file associations for PDF and images to desktop apps, and never sees the Metro environment.

Buying Windows 8? Kind-of, but will never run a Metro app.

17CD John Martyn download set offered for pennies across the web

A recently released 17 cd box set, “The Island Years”, collecting most of the recorded works of singer, songwriter and guitarist John Martyn (who died in 2009) is being offered at download stores from just £1.29 – which is just over 7.5p per CD and less than 0.5p per track.

image

The offers, which have been available for several days, are on reputable download stores including Google Play, Amazon MP3 and Rakuten Play.com.

image

The physical box is around £150 which suggests that the bargain offers are some kind of mistake, but one that is replicated around the web on different music stores. Did someone at Universal Music mis-tap a number? Or is it a sign of some kind of automatic pricing algorithm, where one store sets a wrong price, and the others replicate it so as not to be outdone?

Or maybe someone is a John Martyn fan and wants the widest possible audience for what is a remarkable body of work? No, scrap that idea.

Sunspider JavaScript Benchmark on 4 models of Microsoft Surface

Today I got my first sight of Microsoft’s new models of Surface, its Windows tablet, on display at the Microsoft Store in Bellevue.

image 

I ran the Sunspider JavaScript benchmark on the new models, and then on the old ones for comparison.

  • Surface RT 1.0: 922ms
  • Surface 2.0 (RT): 397ms
  • Surface Pro: 127ms
  • Surface Pro 2.: 114ms

No surprises; but what this confirms is that Surface 2.0 RT, which has an NVIDIA Tegra 4 chipset, is substantially faster than the earlier Tegra 3 model; whereas Surface Pro which has an updated Intel Core i5 processor is only a little faster on this particular test.

Microsoft is attempting to continue selling Surface RT alongside Surface 2.0 RT, at $349 vs $449 for the 32GB model. However the new one is a better buy and I imagine the price of the earlier model will fall further, given that Microsoft appears still to have substantial stocks.

Dear audio industry, fix mastering before bothering with high resolution

4 Comments

The audiophile world (small niche though it is) is buzzing with a renewed interest in high resolution audio, now to be known as HRA.

See, for example, Why the Time is Right for High-Res Audio, or Sony’s new Hi-Res USB DAC System for PC Audio, or Gramophone on At last high-resolution audio is about to go mainstream, or Mark Fleischmann on CD Quality Is Not High-Res Audio:

True HRA is not a subtle improvement. With the best software and hardware, a good recording, and good listening conditions, it is about as subtle as being whacked with a mallet, and I mean that in a good way. It is an eye opener. In lieu of “is that all there is?” you think “wow, listen to what I’ve been missing!” … The Compact Disc format is many good things but high-res it is not. It has a bit depth of 16 and a sampling rate of 44.1 kHz. In other words, it processes a string of 16 zeroes and ones 44,100 times per second. Digitally speaking, this is a case of arrested development dating back to the early 1980s. We can do better now.

As an audio enthusiast, I would love this to be true. But it is not. Fleischmann appears to be ignorant of the Nyquist-Shannon sampling theorem, which suggests that the 16-bit/44.1 kHz CD format can exactly reproduce an analogue sound wave from 20–22,050 Hz and with a dynamic range (difference between quietest and loudest signal) of better than 90Db.

Yes there are some ifs and buts, and if CD had been invented today it would probably have used a higher resolution of say 24-bit/96 Khz which gives more headroom and opportunity for processing the sound without degradation; but nevertheless, CD is more than good enough for human hearing. Anyone who draws graphs of stair steps, or compares CD audio vs HRA to VHS or DVD vs Blu-Ray, is being seriously misleading.

Yes, Sony, you are a disgrace. What is this chart meant to show?

image

If shows that DACs output a bumpy signal it is simply false. If it purports to show that high-res reproduces an analogue original more accurately within the normal audible range of 20-20,000 Hz it is false too.

As an aside, what non-technical reader would guess that those huge stair steps for “CD” are 1/44,100th of a second apart?

The Meyer-Moran test, in which a high-res original was converted to CD quality and then compared with the original under blind conditions (nobody could reliably tell the difference), has never been debunked, nor has anyone conducted a similar experiment with different results as far as I am aware.

You can also conduct your own experiments, as I have. Download some samples from SoundKeeper Recordings or Linn. Take the highest resolution version, and convert it to CD format. Then upsample the CD quality version back to the high-resolution format. You now have two high-res files, but one is no better than CD quality. Can you hear the difference? I’ve yet to find someone who can.

Read this article on 24/192 Music Downloads … and why they make no sense and watch the referenced video for more on this subject.

Still, audio is a mysterious thing, and maybe in the right conditions, with the right equipment, there is some slight difference or improvement.

What I am sure of, is that it will be nowhere near as great as the improvement we could get if CDs were sensibly mastered. Thanks to the loudness wars, few CDs come close to the audio quality of which they are capable. Here is a track for a CD from the 80s which sounds wonderful, Tracy Chapman’s debut, viewed as a waveform in Adobe Audition:

image

And here is a track from Elton John’s latest, The Diving Board:

image

This everything louder than everything else effect means that the sound is more fatiguing and yes, lower fidelity, than it should be; and The Diving Board is far from the worst example (in fact, it is fairly good by today’s standards).

It is not really the fault of recording engineers. In many cases they hate it too. Rather, it is the dread of artists and labels that their sales may suffer if a recording is quieter (when the volume control is at the same level) than someone else’s.

Credit to Apple which is addressing this to some extent with its Mastered for iTunes initiative:

Many artists and producers feel that louder is better. The trend for louder music has resulted in both ardent fans of high volumes and backlash from audiophiles, a
controversy known as “the loudness wars.” This is solely an issue with music. Movies, for example, have very detailed standards for the final mastering volume of a film’s
soundtrack. The music world doesn’t have any such standard, and in recent years the de facto process has been to make masters as loud as possible. While some feel that overly
loud mastering ruins music by not giving it room to breathe, others feel that the aesthetic of loudness can be an appropriate artistic choice for particular songs or
albums.

Analog masters traditionally have volume levels set as high as possible, just shy of oversaturation, to improve the signal-to-noise ratio (SNR). With digital masters, the goal
is to achieve the highest gain possible without losing information about the original file due to clipping.

With digital files, there’s a limit to how loud you can make a track: 0dBFS. Trying to increase a track’s overall loudness beyond this point results in distortion caused by
clipping and a loss in dynamic range. The quietest parts of a song increase in volume, yet the louder parts don’t gain loudness due to the upper limits of the digital format.
Although iTunes doesn’t reject files for a specific number of clips, tracks which have audible clipping will not be badged or marketed as Mastered for iTunes.

Back to my original point: what is the point of messing around with the doubtful benefits of HRA, if the obvious and easily audible problem of excessive dynamic compression is not addressed first?

None at all. The audio industry should stop trying to mislead its customers by appealing to the human instinct that bigger numbers must mean better sound, and instead get behind some standards for digital music that will improve the sound we get from all formats.

Fixing a slow Lenovo laptop

3 Comments

Here is a problem I’ve not seen before. A Lenovo Thinkpad E530 laptop running Windows 7, which after working fine for months developed a critical problem. On start up the user would see the network icon in the notification area (bottom right) show a busy icon or a red cross. No network connectivity, and the machine almost unusable.

After around 20 to 25 minutes the network sprang into life and everything was fine, until the next reboot when the problem repeated.

I fixed several errors in the event log to no avail. The problem persisted.

Went into msconfig and did the usual trick of disabling all non-Microsoft services and startup items. Everything worked fine. Laptop booted quickly and connected to the network.

What was the culprit? Trial, error and instinct eventually narrowed it down to an Intel service: Bluetooth Device Monitor. If enabled, 25 minute boot. If disabled, two minute boot.

I updated the Intel Bluetooth driver, a substantial 300MB download. This fixed it. I noticed that the updated Bluetooth Device Monitor now says it is from Motorola:

image

I understand it was always provided by Motorola but previously signed by Intel.

Posted here in case others run into this issue.

Update: this seems to be a common problem. It seems that a recent Microsoft update is incompatible with some versions of the Bluetooth driver. See here for discussion on the HP support forums, where it has occurred with the HP Probook 4540s and others.

As noted in the comments, I used Lenovo’s system update utility to grab the more recent “Motorola” driver. It shows there as an optional update.

Fix screen dimming unexpectedly in Windows 8

Symptom: you are working away on your laptop or tablet, and suddenly the screen dims. Moments later, it brightens. Annoying and distracting.

The reason is the ambient light sensor. Someone thought it would be smart if the brightness of the screen varied according to the level of ambient light. If the room is more dimly lit, your screen does not need to be so bright. Microsoft’s Surface Pro, for example, has this enabled by default.

The idea is reasonable, but the implementation is lacking. Instead of the brightness gradually varying so you do not notice it, it dims and brightens like a mad thing.

You can fix this in Windows 8 through the power options – no it is not in display options so don’t bother looking there.

If you have a battery/mains icon in the notification area in the task bar, you can right-click and choose Power Options. Otherwise, open Control Panel (desktop version), and search for Power options.

Now click Change plan settings for the currently selected power plan.

Then click Change advanced plan settings.

Now scroll down to Display and expand the tree.

image

The setting you want is Enable adaptive brightness. You can set this separately for mains and battery power. It does slightly extend battery life, so you might want to leave it On for battery and Off for when plugged in.

Then click Apply and close the dialog.

A great big phone: Samsung Galaxy Mega review

3 Comments

How big can a phone go? Samsung seems to be testing the limits with the 6.3″ Samsung Galaxy Mega. How big is that? Here it is laid over a paperback book:

image

In fact, open the book, and the Galaxy Mega proves to be almost exactly the size of the printed area on the page, suggesting that this would make an excellent e-reader. I installed Amazon Kindle and so it does, though the screen is a little too glossy and the battery life too short for perfection.

Hold it to your ear though, and the Mega is big enough to feel faintly ridiculous, outside of places like San Francisco where daft-looking gadgets are the norm. That said, it is slim and smooth in the hands – maybe a bit too silky, it would be easy for it to slip out of your hands – so carries its bulk with good grace.

If you are constantly on the phone, and do not use a headset, the Mega is unlikely to be for you. Still, for many of us voice calls are a long way down the list of reasons for carrying a smartphone. Internet, games, email, text messaging and photography may well be higher.

What about writing and spreadsheeting? I got out my favourite Logitech Bluetooth keyboard, installed OfficeSuite Pro from Mobile Systems Inc, and started to type.

image

I can get real work done on this; but I am unlikely to choose to do so. In fact, the screen size is not the problem. There are other issues. One is that the Galaxy Mega should be supplied with a prop-up cover or stand, since for functions like word processing with a keyboard, or watching YouTube or BBC iPlayer, it is best stood up on its side. Another is that the Android OS and its applications seem primarily designed for touch. The on-screen keyboard seems to pop-up even when not required, though ESC usually dismisses it, and getting at the formatting controls is just a bit awkward.

I also found that I could easily out-type OfficeSuite Pro on the Mega. I thought this might be an OS issue, but Infraware’s Polaris Office (which comes free for download with the Mega) is better in this respect, though less good overall than OfficeSuite Pro.

As a productivity device then, the Mega is not quite there and I will still want to take a Surface RT or some other suitable device on the road. It does work though, which has some appeal, and note that these Office suites also work well as viewers for Microsoft Office formats.

The hardware

Open the box, and you will see that, other than size, there is little else notable. Mine came with a 4GB SD card included.

image

The device feels solid and well-made. The audio and headset jack is on the top edge, volume rocker on the left, and power on the right. On the front, at the base, is the home button. There are also soft buttons to its right and left for Menu and Back. These are backlit, but the backlight is usually off, which means you have to remind yourself at first that they really are there. I am not sure why Samsung does not put a little etching to indicate their presence.

The screen is great, though I would prefer less gloss, but it is bright and responsive so no real complaint.

The camera is decent but unspectacular. Good enough that most users will be happy, but not good enough to attract photo enthusiasts.

Battery life is decent, though not outstanding. 24 hours of normal usage will be fine, but over two days you will likely need a charge.

One thing worth emphasising: the Galaxy Mega may be bigger than the S4, but it is less powerful. The S4 has a quad-core 1.9GHz chipset, 13MP rear camera, 16GB memory, 1920×1080 resolution, and so it goes on. You are going to buy the Mega over the S4 for only two reasons: price, or because you really want that big screen.

Software

The Galaxy Mega runs Android 4.2 Jelly Bean with Samsung’s TouchWiz interface. I doubt anyone will have trouble with basic navigation, but it fails to delight.

One of its notable features is called Multi-Window. This runs as a pull-out application launcher, by default docked to the left of the screen. Here is the tab, which annoyingly obscures some text:

image

and here it is pulled out:

image

If you perform the right gestures with the right apps (not all of them work) you can get two apps running side by side by pulling them out from the bar:

image

The vertical bar lets you resize the apps freely.

I think this whole thing is a mistake. While having two apps to view seems useful, even the Mega’s screen is not large enough to make it work with desktop-style convenience, and Android apps are designed for full-screen use. Nor do I like the bar as an alternative app launcher; it is unnecessary and gets in the way. This is another example of an OEM trying to improve an OS and making it worse. It is not too bad though, as you can easily disable it (drag down from the top and tap Multi-Window so it fades).

Incidentally, I had trouble getting a screenshot of the multi-window bar. The normal approach failed as touching any button makes it retreat. I used the deprecated DDMS in the ADK (Android Developer Kit). This required finding the Developer Options on the device. Bizarrely, you enable Developer Options by repeatedly tapping Build number in About Device. Odd.

Samsung store and apps

In its effort to make its devices distinct from other Android devices, Samsung is building its own ecosystem, including the Samsung app store which is prominent in the default configuration.

 image

What is the value for the user in this, given that the official Google Play store is also available? None, other than that it is good that Google has some competition. That said, this is where you can get Polaris Office for free, which is worth having.

Similar examples of duplication versus Google’s ecosystem are evident elsewhere, for example Samsung’s ChatOn versus Google Talk (now Google+ Hangout), though ChatOn does not do voice or video; and Samsung cloud backup versus Google’s cloud backup. For example, photo backup to Samsung’s cloud (once you register) is on by default; but this feature is also available in Google+, for Google’s cloud.

Overall this is confusing for the user and I am not sure how this game ends. It contributes to a sense that Android remains messy and disorganised versus Apple iOS or even Windows Phone, though in compensation it has wonderful functionality.

Samsung Air View is an attempt to bring the benefits of mouse hover to a touch interface by detecting the finger over the screen. For example, you can preview an email message.

image

Plenty of potential here; though I found it unreliable. I still have not got magnification in web pages to work, despite turning this on in settings.

WatchOn lets you control your TV via an app that shows what is on. This worked for me though it feels like solving a problem I do not have.

The Music app isupports DLNA; but while it detected my Logitech Media Server I had trouble playing anything without stuttering.

Summary

There is a lot packed into the Mega and I have not done it justice above, but picked out some highlights. It is highly capable; but I hesitate to recommend it unless the combination of a large screen and a smartphone is perfect for you; if you do lots of web browsing, email and YouTube, but not many phone calls, or if your eyesight is such that having everything a bit larger is an advantage, it could be just the thing.

The disappointment is that Samsung has not made more sense of the large screen. The Multi-Window feature is not good, and in the end it just feels like a big phone. The fact that its spec is well behind that of the Galaxy S4 is another disadvantage.

The Galaxy Mega also exhibits the Samsung/Android problem of duplicated functionality, contributing to a user experience that is less tidy and more confusing than it needs to be.

Personally I am hopeful for the day when a single device will simplify my life and I will no longer have to carry phone, camera and tablet or laptop. This one does not get me there; but maybe with a bit more refinement a future iteration will.

Review: Innergie PocketCell pocket battery charger: elegant design though limited capacity

Smartphone battery life has marched backwards, or so it seems: my ancient HTC Desire still lasts longer on a full charge than my newer Nokia Lumia 620 or Sony Xperia T. Another problem is tablets: battery life is decent compared to a laptop, but it is easy to get caught towards the end of the day or on a plane with an exhausted battery.

The solution, if you cannot get to a charger, is one of those pocket chargers for topping up your device. These are popular promotional giveaways, which means I have a drawer full of them (or would if I had kept them); but many are rubbish: bulky, fiddly with lots of assorted adapters to cope with different phones, and some with pointless adornments like solar panels.

I make a partial exception for a PowerTrip charger I received recently, which has an impressive 5700mAh battery, but it is still ugly, comes with three cables, and has silly extras like a solar panel and ability to work as a memory stick.

By contrast, the Innergie PocketCell is the first charger I have seen which has immediately impressed me with its design.

image

There are only two pieces you need to carry with you, the small battery pack itself and a clever three-in-one cable in which the adapters snap together, so you can charge a device with Mini-B or Micro-B USB (the two popular types), or an Apple 30-pin dock connector (if you have an iPhone 5 or another device with the new Lightning Connector you are out of luck unless you have an adaptor).

image

The same connector also serves to charge the PocketCell, using one of the many USB mains chargers you almost certainly already possess, or by plugging into a PC or Mac. The PocketCell has a USB Type A socket for output, and a Micro-B for input, so you cannot easily get it wrong.

On the side of the PocketCell is a button which you press to discover the current charge. It lights up to four LEDs, to indicate the level of charge remaining.

Battery capacity is 3000 mAh; not as good as a PowerTrip, but decent considering that it is less than one-third the size and much lighter (72g/ 2.5oz).

I tried the PowerCell on an iPhone 4 with a fully expired battery (at least, expired to the point where it would not switch on).

image

The phone charged successfully, during which time the PocketCell got somewhat warm, but with impressive speed of charge. After the charge the PocketCell was pretty much exhausted.

The PocketCell supports 2.1 amp fast charge, which means it is fine for charging an iPad or other tablets with USB power.

The small size, nice design, and effective charging of the Innergie PocketCell means this device might actually find its way into your bag. The downside is that it is more expensive (especially in the UK) than some other portable chargers with equal or greater capacity, but its elegance and usability is worth a bit extra.

While I recommend the device, check that 3000 mAh is sufficient for you before purchase. I have also heard that the three in one cable is a little delicate, though you can get replacements if necessary or use a standard USB cable.
