Interoperable Acquisition

At the tail-end of last year, the SEI (Software Engineering Institute) published a paper on ‘Interoperable Acquisition for Systems of Systems‘. Although it has a defence slant (the SEI is largely funded by the US military), there seems to be some considerable relevance for organisations interested in adopting SOA and/or a multi-sourcing model for their IT systems. I struggled through the paper, wincing at the callous mangling of the English language*, only to find that the conclusion was that governance around the procurement, construction and operation of ‘Systems of Systems’ was really hard and the authors wanted more research funds to figure out the solution to the problems. Contrast this with the current hype around SOA as the solution to all an organisation’s IT issues. So the message for us is that we should be careful about diving in to the SOA pool, particularly about what we promise our customers, and that wherever there is uncertainty, there is a consulting opportunity

*The most painful being the use of ‘fielded’ when they appeared to mean ‘deployed’ or ‘in use in the field’. I hate it when they verb nouns like that.

Essential Reading?

Reg Developer just asked the question "Do you own these bookshelf must-haves?". Clearly, they just want to boost their associate fees from Computer Manuals, but it is an interesting topic for discussion. I own a few of them, although my copy of Petzold is a bit out-of-date. I've always wanted a set of Knuth's books, but when I put them on my Christmas list I generally get told I'm being too 'sad', whatever that means. What about you?

Orange SPV M600 and Pocket PC Reviewed

I am a long term Palm user - my first Palm device was a PalmPilot Personal in 1997. I wrote some impressions of my then new Palm TX just over a year ago. Just before Christmas 2006 I took delivery of my first Pocket PC, an Orange SPV M600. I have also spent time with a Windows Mobile Smartphone, an Orange SPV C500, where I found the Smartphone facilities so hard to use that I didn't bother - it was pretty rubbish as a phone too. This review will cover my opinions of the new device and the OS.

Hardware
I'm not going to spend a lot of time describing the hardware; the M600 is one of the many versions of the HTC Prophet (others include the iMate JAMin, the Qtek S200, O2 XDA neo), the specs are on the Orange pages and if you go to 'Help and Support' you can download a pdf of the user manual. To summarise, the phone looks cool in its slightly rubberised metallic finish, it is small enough to be held to youre ear as a phone without making you feel ridiculous, the QVGA screen is bright and clear and the overall feel is solid. Some colleagues have drop tested their M600s and they have proved to be quite robust.

Presumably to increase battery life, the M600 uses a relatively slow TI OMAP 850 200MHz processor. This tradeoff makes sense most of the time; the exception being graphically intensive operations like changing the screen orientation from portrait to landscape, which is painfully slow, and turning the camera off which is even more excruciatingly glacial. Coupled with the position of the camera button where it is easy to press it by accident this causes a slgnificant issue; I have resolved this by re-assigning the camera button to bring up the Today screen instead, leaving camera access via the Start menu.

Phone
As a phone the M600 is very good. On all the attributes that matter - call sound quality, signal strength and reliability - it scores highly. Even battery life is not bad, comfortably outlasting the C500, although heavy PDA use reduces this (presumably due to the backllght, which is very bright), as does using Bluetooth or Wi-Fi. Integration with the PIM Contacts list is very good, some compensation for the lack of a hardware keypad. The soft keypad is usable with your fingers, so you don't need to get the stylus out to make a call. The designers have also thought about one handed use whlch is generally possible using the 5-way navigator and 4 hard buttons. Bluetooth to a Jabra BT250 headset works well, with good range and the speech recognition is tolerant of different environments and background noise. Overall it's as good as a phone from the traditional suppliers such as Nokia and Sony Ericsson, which is all one can really ask for.

PDA
OS and ActiveSync
My first impression of the OS is that it is chaotic - the developers clearly had no agreed UI guidelines, or if they did there was no QA to ensure that they were followed. Each app, or sometimes each dialog within an app seems to have a different way of confirming actions. All the UI constructs (pop up menus, OK buttons, 'Done' buttons or menu items) seem to be used at random, and you have to hunt around the screen to find things. This is in huge contrast to the Zen of Palm, and considering the amount of money Microsoft have spent on this stuff it is frankly unforgivable.

Then there's this nonsense about the close button not closing apps, so that your available memory gets gradually eaten up. The remedy is to burrow several layers deep into the menus and find 'Running Programs' in the Memory applet and close a few apps down. If that doesn't free up enough memory, then just reset/reboot the machine. This is a hassle I could do without, and again sharply contrasts with the simplicity and usability of the Palm. So while a lot of the individual pieces are pretty good, the overall impression is that Pocket PC is a rather amateur effort.

And then there is ActiveSync. This is another area where the amateurishness makes itself felt. The UI on the PC side is just weird. If you try to see if you can configure sync for Notes, a dialog tells you that there is nothing to configure. There is nothing to configure for Contacts either, but in that case it tells you by simply presenting a 'Settings...' option, but it is always greyed out. Then there is the 'Resolve Items...' command. This appears in the middle of an information area of the application window when Active Sync has failed to sync something. Although the rest of the application is a rich client using Windows controls, this one looks like a hyperlink - blue, underlined - and following the Windows UI guidelines the elipsis (...) means that clicking it should take you to another dialog. But it doesn't - it just seems to run a Sync again, which will usually fail, for whatever reason it originally did. At no time does it suggest a cause for the failure, or any corrective action you might take. The whole thing looks and works like an early beta, not something at version 4.2. When it works, the continuous syncing is quite handy, compared to the sync on demand approach of Palm Hotsysnc. The trouble is that it doesn't seem to be very reliable or dependable.

Text Entry
I'm writing this using Notes on the M600. Of the text entry methods available to me I've chosen to use letter recognition, and I already seem to be faster with it than I was with Graffiti - I was a big Graffiti user, at least until the TX's broken character recognition put me off. Other options are the Block Recognizer - a Graffiti clone, Transcriber - cursive script recognition and a pop-up keyboard. All feature word completion which works well once you get used to it and increases the overall speed of entry.

Calendar, Contacts, Tasks and Notes
The PIM apps are a match for the standard Palm equivalents, but for my calendar and address book I'd got used to the excellent TMP and Address XT, and compared to these the Pocket PC versions are a bit disappointing. I've mentioned phone integration with the Contacts application before, and it really is very good. I find it easy to find a contact and call them, either without the stylus, using just the 5-way navigator, or by writing part of their name into the search field. The possible hits are shown as you write, so you just need to write enough to get the person you want into the visible search list. It would be even easier if you could filter your Outlook contacts that get synced as you could with Windows Mobile 2003. This option has disappeared from PPC 5.0 and if you have nearly a thousand contacts it is a bit of a pain. I used to be able to add a category to the one hundred or so contacts I wanted on the phone, and ActiveSync just copied those. Now I get the lot, with obvious consequences for memory use and usabiity. While we are on the subject of categories, the Notes app doesn't support them at all, which is again a pain if you have a lot of Notes in Outlook.

Pocket Office
I have not actually tried these apps yet, although I did establish that the Orange supplied ClearVue PDF reader was unable to make sense of anything but the very simplest documents and was therefore pretty much useless. Pocket Word, Excel and Powerpoint don't look as full featured as the Docs To Go apps on the Palm, and syncronisation seems to be more of a manual operation. If I get around to using them I'll post a review then.

Media Player
Another thing I haven't tried is listening to music on the M600. The headphone socket is a 2.5mm effort so I can't use my favourite headphones without an adaptor, and I don't fancy being unable to make a phone call because I used the battery up listening to Warren Zevon. If I get the time I might try it for curiosity's sake, and if I do I might remember to come back and update this report.

Third Party Applications
There were a few things on my Palm that I used regularly - Metro, eReader and Palm Keyring being the most frequently needed. I was pleased to find that there were PPC versions of the first two available at the same cost as the Palm versions - free. These seem to work fine on the M600, and I was pleasantly surprised to find that I could use the eBooks purchased for the Palm on the M600 without any trouble. For the password vault, I'm trying out the open source KeyPass. It's early days yet but it seems to be OK.

The other thing I'm trying out is a utility called Magic Button. This aims to deal with the application shutdown/memory issue discussed above, by actually closing applications when the close button is tapped. Again, this seems to be doing it's job and it is also free.

The Verdict
The only thing I'm still depending on the TX for is waking me up in the morning (using the excellent Palmary Clock), so at the moment it looks like I'm going to be able to stop carrying the TX around, and just use the M600. It works fine as a phone, and the PIM functions are good enough. It's both ironic and extremely surprising that in many ways Microsoft Office and Outlook integration works better on the Palm. The Pocket PC OS is frustrating - it is fairly easy to see where the user experience could be massively improved by actually managing the developers rather than letting them hack away at random. It is interesting that the market is clearly saying that this inconsistency and general flakiness is not a barrier to success - I think a discussion of the reasons for that requires its own post. I'll miss Palm, but probably not enough to make me continue using two devices where I could manage with just the M600.

'No proof' organic food is better

The BBC and many other leaned organs report David Milliband's remarks saying that there is 'No proof' organic food is better.
I think that this is missing the point. It may well be the case that organic food is not better for the person consuming it, but it is unquestionably the case that it is better for the planet, probably better for the farm workers who no longer have to be exposed to the pesticides and other chemicals, and probably better for the animals who are treated so unpleasantly in intensive farming regimes. It is unfortunates that buying organic for such reasons requires a greater level of altruism than buying because it directly affects your health.

Software Development should be fun

Like a lot of people my age, I got into what is now called the IT business because I really enjoyed programming. We didn't really consider the money side of things, or whether it was a long-term career, we just liked messing around with computers. If people were going to pay us for it, that was even better. The word 'geek' came later...

David Intersimone, now Vice President of Developer Relations and Chief Evangelist for Borland Software, has an article on the Dr. Dobbs site called "Why Programming is Fun", which reminded me how I got started. But it isn't just nostalgia for me - I think we need to bring some of that attitude back. I know the last few years have been hard, and projects today are more challenging than they ever were 20 years ago, but these things do not preclude enjoyment. David's article quotes 5 reasons why software development is fun from Fred Brookes legendary "Mythical Man Month":

• The sheer joy of making things.


• The pleasure of making things that are useful to other people.


• The fascination of fashioning complex puzzle-like objects of interlocking moving parts.


• The joy of always learning.


• The delight of working in a tractable medium.

I don't see anything in that list that is less valid today than it was when Brooks wrote it. A critical part of my job, and the job of our sales teams, is to make sure that those aspects of our work are not overshadowed by less positive influences.
