Hardware of the Year

Hardware

Good and bad.

The Olympus 9-18mm MFT lens for my Panasonic G1 is a joy to use, small, light and sharp. Add in my custom distortion correction profiles and you have a cracker of an ultra-wide zoom at a very reasonable price.

After a poor start with the original AppleTV (another Apple Toaster design, running dangerously hot) the second generation AppleTV gets it right and is a tremendous tool for showing your photographs on any big screen TV you connect it to. At $99, with included remote, it’s a bargain.

And finally, if you crave screen area as much as I do, try the Newer Technology USB to DVI adapter which allows you to add up to four displays to your OS X computer. It doesn’t support Quartz rendering (meaning some of the latest screen savers default to black) and does not permit screenshots, but other than that it’s proving to be a powerful addition to my desktop HackPro, which now sports no fewer than three displays.

But it would be disingenuous to write a piece like this without mentioning two genuine stinkers.

One is, by a considerable margin, the worst piece of hardware I have used in a decade, the Kindle. Poorly made, designed by a committee seemingly totally ignorant of the word ‘ergonomics’ and faulty in just about every way imaginable. It simply defies understanding why this piece of garbage sells at all. Sure, you save a few dollars compared to an iPad but then you could save more by not buying rubbish in the first place.

And finally, let’s not forget the Fruit Company which has made some of the least reliable hardware in the history of computing. Yes, that would be Apple. My most heavily used OS X machine is my HackPro simply because I cannot risk making my living on an Apple desktop. My MacBook Air is too new to permit any quality judgements, though the iPad with its cool running A4 CPU augurs well. But I have such an awful history with Apple’s awful hardware that I’m not about to say anything good about the reliability of the company’s computers; I use Macs rather than PCs primarily because of the robust OS and applications they run. Check back here one year hence to see if the iPad and MBA finally start bringing me around on the issue of reliability and heat management.


The best reason to use Apple’s awful hardware.

Computer of the year – 2010

iPad

No surprises here.

A year ago – it seems like a million years ago – I named the MSI Wind netbook the Computer of the Year.

Further, a few days later I wrote of the yet to be announced ‘iSlate’:

Such was my confidence in the iPad, finally released three months later in early April, 2010, that I bought a couple on the opening day and have since given away another half dozen to friends as gifts.

By this time next year another 50 million or so users will get the message but we early adopters have benefitted mightily from the unfair advantage this gadget confers.

So in nine brief months the iPad has obsoleted the netbook and created a whole new way of creating and consuming information, opening up sales to a demographic which would never touch a ‘computer’. Part of the device’s magic is that it really does not bear much resemblance to what we think a computer should look like. And you can take it with you, it weighs little and all you need is an internet – or maybe cell – connection to access the world.

So in a year which was decidedly blah for new gadgets, the iPad reigns supreme, easily being this consumer’s Computer of the Year for lack of any credible competition.

Computer of the year – 2010.

Four displays

Displays

When you are desperate for screen space.

A while back I wrote about using the Air Display Mac application which permits use of the iPad as an external display. After adding my third Dell 2209WA monitor to my desktop rig, I revisited Air Display to see if it still functions, this time as a fourth monitor.

It does!

The iPad is being used as a fourth monitor.

Sure, cursor response on the iPad is a tad jerky as the cursor’s data stream is being sent over the air, but it’s more than acceptable as a peripheral for displaying a screen which rarely needs mouse action, like a live stock price chart, for example.

Here’s how I have System Preferences->Displays->Arrangement set up:

The rarely accessed screen is pushed out to the left.

Note that the blue screen area with the white menu bar is aligned at the base, not at the top – this makes sure straight lines remain straight, rather than stepped, as you mouse across. Also, by relegating the iPad display to the left or right you avoid having to access the jerky iPad screen’s base if that’s where you keep your application icons. I have mine set to hide except in the case of a mouseover, which is why they are not visible in the photograph above.

Remote with an iTunes music server

iPad, Macintosh

A work in progress.

Download Apple’s free Remote app to your iDevice and you get a handy interface for managing your remote music server. I explained how I set up one of these in yesterday’s column.

Start the app on, say, the iPad and this is what you see:

The list of sources appears in the left hand column and the contents in the right. This is the ‘Artists’ view – chosen from the tabs at the base of the screen.

Switch to Albums and you get this – as you can see I still have some work to do to get cover art for all my albums:

And so on. Touching the four arrows at lower right switches you to a blank screen which acts as a touch pad, permitting remote control of menu selections for the AppleTV on the screen of your television. Nice, and a lot more reliable than using a mouse on the sofa cushion!

Touch the ‘AppleTV’ bar in the left hand column and you see your sources on one screen:

The ‘iMac music server’ is the old G4 iMac I set up yesterday to act as a source for all our recorded music.

What is missing, and why I captioned this piece ‘a work in progress’ is AirPlay functionality. You cannot select where to output sound, so when I want to do so, I have go to the iMac music server and do so in the iTunes application there, as I illustrated yesterday. Not a big deal and maybe a constraint placed on Apple by the modest processing power and RAM of the current iPad. Given that each of my three speaker options has its own volume control – TV, Office and Dining Room – I can change or mute any of these when needed. Still, it would be nice to be able to do this from the iPad whose control is limited to pause/fast forward/rewind and play.

The Remote app is nicely engineered, the price is right (as in ‘free’!) and you can download it from the AppStore.

AirPlay with multiple speakers

Macintosh

Full house sound, wirelessly.

This piece gets a bit technical so hold on to your hat; however, it may be helpful for those experimenting with AirPlay routed to multiple speakers simultaneously.

Following up on yesterday’s column on using AirPlay with TuneIn radio on an iDevice, I rooted around and found another set of Logitech powered speakers languishing in the place the black beetles call home in the garage. These are the estimable Logitech Z4i with a powered bass and two satellites, making for excellent sound. Back when I used an iMac G5 and later the ill fated 24″ iMac which fried its GPU thanks to Apple’s crappy design, the satellites velcro’d nicely to the sides of the iMac’s monitor with the bass out of sight under the workspace. I had put them away in favor of smaller desktop speakers when I built the HackPro and had quite forgotten about them.

Well, as the shared Brother printer in the office is attached to an Airport Express (AEX) as a Bonjour printer, naturally I could not leave well enough alone, realizing that I could connect these powered Logitech speakers to the AEX for yet another sound output from any iDevice. A few moments of plugging things in and TuneIn Radio sound on my iPad was coming from these Logitechs.

Now how about full house sound? Well, I can’t see any place where AirPlay on an iDevice permits selection of multiple speakers, though I would bet dollars to doughnuts that this is only a matter of time. Maybe the iPad needs to be upgraded to the multi-core ARM A9 CPU before this becomes possible. However, firing up iTunes on the HackPro, where my extensive music library resides, I clicked on the AirPlay logo and this is what I saw:

AirPlay on iTunes and the HackPro.

Clicking on ‘Multiple Speakers’ I got this selection panel:

The multiple output panel in iTunes.

I checked off all the speakers and adjusted the volume but …. the sound keeps cutting out. Selecting just the HackPro’s speakers (“Computer”) all is fine, but select any other destination alone or in addition and the sound cuts out.

Going to Utilities->Audio MIDI Setup I adjusted the output settings to the least demanding, thus (2ch-24bit is the default):

Audio MIDI settings.

This reduced the cutting out but did not eliminate it, so I’m guessing there’s some glitch either in my wifi system (the HackPro where iTunes runs uses 2.4gHz 802-11n wifi as I cannot use pure 802-11n at 5gHz as I need the 802-11g mode for compatibility with my iPhone, and do not own the latest dual band Airport Extreme). All my sound files are in uncompressed format, meaning they are large, for maximum quality. MP3 is a poor, over-compressed format for sound fidelity. The file size doubtless is not helping matters.

For further diagnosis I went to the MacBook Air which uses 802-11n wireless, started iTunes and tried playing a track stored locally in iTunes on the MBA. Perfect. I could enable all remote speakers and all played fine with individual volume control available for each, suggesting that the lower speed of the 2.4gHz 802-11n on the HackPro may be a limiting factor. There are a lot of variables here so it could well be something else, but I expect I’ll get there through a process of elimination.

Getting ambitious, I next loaded the remote library on the MacBook Air from the HackPro, where iTunes->Advanced->Turn On Home Sharing is set to ‘On’. Well, the stuttering, while greatly reduced, was still there so clearly there is a bandwidth or speed issue with the HackPro which looks like it needs 802-11n. Meanwhile, I’ll just move my favorite tunes from the iTunes library on the HackPro to the one on the MacBook Air for those occasions when whole house sound is called for.

An encouraging experiment.

Update: A solution to the stuttering problem:

I put on the old thinking cap and took the resident Border Terrier for a walk. Always clears the mind, I find. I had never paid any attention to the sound technology in the HackPro where my iTunes library resides. All I need it to do is drive pokey desktop speakers for the usual mail sounds, etc. I do not listen to music through its speakers. Its 802.11g should be more than adequate for routing sound files, even if uncompressed. So could it be the Digital to Analog Converter in the HackPro that was choking? Well, I fired up that ancient old iMac with the 1.25 gHz IBM G4 CPU and a scant 1 gB of RAM which we have owned some ten years now. It’s mostly used for web surfing and is by far the most reliable Mac I have ever owned.

I reckoned that I would simply update iTunes on the iMac (which runs Leopard, the last version of OS X supported on the G3/4/5 CPUs) and then point iTunes to the library of music on the HackPro. While the iMac uses 802-11n it would still be no faster than 802-11g as the slowest component in the equation is the HackPro and it’s 802-11g. But, and here’s the key, I would be using the iMac’s DAC to convert the digital stream to analog sound and my bet was that even the ancient DAC in the iMac would be pretty good, given Apple’s focus on sound reproduction.

And this proved to be the case! I told the iMac to send sound to three speaker sets (Apple TV, Office and Dining Room) and it is playing perfectly for the past hour. If it does start to stutter, I’ll simply move the library of music to its internal hard drive, taking the HackPro’s poky wifi out of the equation, but so far it’s working fine. I suppose I could also place the iTunes files on an external hard drive connected to the iMac but Apple has said that it does not support external HDDs for use with AirPlay, so I’m not pushing that angle. It may work. It may not. What is tremendous is that not only does this ancient hardware support AirPlay with the latest iTunes download (congratulations, Apple!) but sports a decent DAC which is better than the PC-grade one in the HackPro.

This analysis seems to make sense. The old iMac is receiving a digital file and locally converting it to analog. The original approach had the HackPro sending out an analog file to the speakers and, I’m guessing, that’s larger than the pre-DAC-processed digital file. The speakers attached to the HackPro worked fine with no stuttering as they are hard wired, whereas the remote ones stuttered owing to their use of wifi for reception. So it’s either a slow DAC in the HackPro or the lack of 802-11n in that machine.

Another alternative is to retrofit the HackPro with a better DAC but, frankly, I can’t be bothered and so far my total investment in this project is one AEX for $88. That’s enough!

Bottom line? If you have an old G3/4/5 Mac in the home, consider making it a music server for use with AirPlay.

Meet my new old music server.

Second update:

After two hours of music play I would still get the occasional stutter. So I moved my iTunes library to the internal drive of the G4 iMac and loaded the library from there. After two further hours of listening there was no more stuttering.
