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 I own a few of them, although my copy of Petzold is a bit out-of-date.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.

Sect Schools

Any of you who think that so called 'faith schools' are only encouraging and promoting divisiveness and conflict might be interested in this online petition, which:

• proposes the term "sect school" in place of the term "faith school"
  


• calls for amendments to the Education Bill (published 28th February 2006) to prevent the further proliferation of sect schools in the UK
  


• calls for an end to state-funded education which is controlled by any religious group or affiliated with any religious beliefs
  

More at The Brights.

Edit: You can also petition the UK government direct at http://petitions.pm.gov.uk/nofaithinschools/, although this may just be a ploy to gather names and addresses so that they can send the black vans round. Paranoid, me?

Bad Code

The "Bad Code" posting on Wired's 27B Stroke 6 blog is both funny and sad. I can't add much to it, just go and read. If you aren't a coder, a little bit of background research might be needed, but it isn't too hard.

big and bad

I was cycling around Warwickshire in an eco-friendly sort of way at the weekend, and in between the excessively frequent stops to repair the damage caused by the visits of the puncture fairy I was thinking about SUVs. Probably prompted by the amount of time one has to spend as a cyclist trying to avoid being killed by them, I was trying to figure out why a) they existed at all and b) why they sold in such numbers. Engineers are generally rational people, so why would they create something quite as preposterous as a Porsche Cayenne Turbo? Obviously, they did it because they wanted to keep their jobs and feed their children, but apart from relishing the challenge of building a 2 tonne off-roader that will go from 0-60 in under 5 seconds, can they really have felt happy about what they were doing? Engineering is about solving problems, but the modern SUV solves very few problems while creating rather a lot of them. In the beginning, SUVs existed as workhorses, to be used by farmers, foresters, explorers and construction workers to get places ordinary cars couldn't go. If you've ever been in a Willys Jeep or a Series 1 Landrover, you will appreciate just how utilitarian these utility vehicles were. Then for many years, the Range Rover was the only 'luxury' 4x4, sold to the landowners rather than their staff, and just as acceptable in Mayfair as in the country. The wider popularity of alleged off-roaders was driven by the American market (the Cayenne and the BMW X5 were created for that market), and according to the American Automobile industry, SUV purchasers

"tend to be people who are insecure and vain. They are frequently nervous about their marriages and uncomfortable about parenthood. They often lack confidence in their driving skills. Above all, they are apt to be self-centered and self-absorbed, with little interest in their neighbors or communities."

(Keith Bradsher, "High and Mighty: The Dangerous Rise of the SUV")

So the problem SUVs solve is how to sell more vehicles to vain, selfish, nervous people, and for that the rest of us must accept unnecessary levels of pollution, increased accident risks and many other reductions in our quality of life. Would it not have been a btter engineering solution to invest in some education and therapy?

Fruitstock

Just got back from a day at fruitstock with my children. What inspired marketing! For less than the cost of a TV advert, Innocent make a lot of friends,, enhance their cool image, and give a lot of people a good time. As you can see from the picture, it was pretty popular.

Welcoming Homer the tree-hugger

In his post in the BBC's Green Room series, George Meyer welcomes hypocrites to the green cause. Because even hypocrites are better than evironmental rapists who neither know nor care what damage they do. He says:

We will now accept:

* Ignoramuses
* Poseurs
* Backstabbers
* Know-it-alls
* Opportunists
* Busybodies
* Hypocrites (like me)
* People Who Talk a Good Game
* Total Nutjobs

It's wide open. If Michael Crichton ever comes to his senses, we'll even take him. He's a big fellow, maybe he can lug around pamphlets or something.

It's a fair point - the recent evidence of the speed with which the glaciers and ice-caps are shrinking makes it clear that the change is real and accelerating. It is no time to be snobbish about who's on board the bus.

Don't go quietly

In 1988 the following text was published in full page advertisements in the quality papers:

We have had less freedom than we believed. That which we have enjoyed has been too dependent on the benevolence of our rulers. Our freedoms have remained their possession, rationed out to us as subjects rather than being our own inalienable possession as citizens. To make real the freedoms we once took for granted means for the first time to take them for ourselves.

The time has come to demand political, civil and human rights in the United Kingdom. We call, therefore, for a new constitutional settlement which will:-

• Enshrine, by means of a Bill of Rights, such civil liberties as the right to peaceful assembly, to freedom of association, to freedom from discrimination, to freedom from detention without trial, to trial by jury, to privacy and to freedom of expression.
  Subject Executive powers and prerogatives, by whomsoever exercised, to the rule of law.


• Establish freedom of information and open government.


• Create a fair electoral system of proportional representation.


• Reform the Upper House to establish a democratic, non-hereditary Second Chamber.


• Place the Executive under the power of a democratically renewed Parliament and all agencies of the state under the rule of law.


• Ensure the independence of a reformed judiciary.
  Provide legal remedies for all abuses of power by the state and by officials of central and local government.


• Guarantee an equitable distribution of power between the nations of the United Kingdom and between local, regional and central government.


• Draw up a written constitution anchored in the ideal of universal citizenship, that incorporates these reforms.

The inscription of laws does not guarantee their realisation. Only people themselves can ensure freedom, democracy and equality before the law. Nonetheless, such ends are far better demanded, and more effectively obtained and guarded, once they belong to everyone by inalienable right.Add your name to ours. sign the charter now!

That was Charter 88; signatories were led by Lord Scarman and many other high profile figures from the law, civil service, politics, media and business. How much progress have we made in nearly 20 years? You can still follow that link and add your name, and you can still apply pressure for our democracy to be made as good as we like to think it is.

Please send money now

For years, I have deliberately avoided skiing, as the last thing I need is another expensive hobby, especially one that also demands large chunks of my annual leave. Then, last autumn, my wife suggested that we share a chalet with some friends. We quickly realised that we'd left booking a bit late but eventually, having got nowhere with internet searches and so-called specialist ski agents, our local travel agency found us a place in Les Deux Alpes for the February half-term week. The most expensive week in the calendar :-(

So that I wouldn't look a complete muppet when I got there, I booked a 'Learn to Ski in a Day' session at the Snowdome in Tamworth. That was well worth the money, and the instructor was excellent. More than can be said for me. My excuse is that my unicyclist insticts are just all wrong for skiing.

Once in Les Deux Alpes, for the first couple of days, I was just crap. I heard what the instructors said, but I just could not make it happen. I lay in bed at the end of day 2 thinking that I had just wasted thousands of pounds (family of 5 in peak week) - I was really quite fed up. By day three, I was just getting the ocasional feeling that I'd got it right and I was feeling better about it. On day 4 I forgot my lift pass and had to miss the lesson, so I got to spend the morning just practising the things that I felt I needed to. That really helped, and by day 6 I'd got it and was hooked. Now my problem is how to find the money to do it at least once every year.

Never apologise never explain

Right

Cowards complain as Ramsay kills turkey

I'll admit to a degree of bias on this report from BBC News as I'm a vegetarian. However it seems quite clear to me that people who complain about seeing where their food comes from are just being cowards. If you don't like the fact that cute little animals get killed for your pleasure, then don't eat them. I would go so far as to say that you should be prepared to kill them yourself, or you shouldn't be eating them. Why should someone else be expected to do your dirty work?

This is the argument at the heart of my vegetarianism - I'm not particularly sensitive about cute little animals, although I think that mistreating any living thing is probably bad for the people who do it, as well as the victims. I don't have a religious objection as I don't have a religion. It just seems counter to my conscience to ask others to do things that I am not comfortable doing. Just don't ask where that conscience comes from - I have no idea.

Merry Hell

A BBC News Magazine article entitled Merry Hell talks about the effect evil minority pressure groups, such as the one that caused so much trouble over 'Jerry Springer: The Opera' earlier this year, can have on retailers. Sainsburys and Woolworths have pulled the DVD of the show from their shelves following complaints. It suggests that bloggers and other rational people are capable of writing more complaints than a bunch of nutters. Sounds like a plan...
I was thinking of boycotting them until I realised that it would leave me without a source of food. The supermarkets have pretty much done for the independent retailers around here. I'm boycotting ASDA because of Wal-Mart's atrocious human rights record, both with their direct employees and those of their suppliers, Tescos because I just don't think it is healthy for one company to be so dominant and Waitrose don't have a store that I can get to without burning unacceptable quantities of fossil fuels. So if I refused to shop at Sainsburys I'd get hungry. If only Ocado would improve their site design so that it didn't take longer to place an order than it does to drive round to Sainsburys and just buy the stuff.

Ends and means

Condi Rice's statement today sounded awfully close to a claim that the end justifies the means. US foreign policy has always seemed to have an element of 'might is right' about it, but as soon as you start to suggest that anything is permissible if it prevents terrorism, it seems to me that you have adopted the terrorists logic. And if you have adopted their logic, their morality goes along with it. Once you have thus surrendered the moral high ground, you will be locked into an escalating cycle of violence which no-one can win. Someone in the US State Department needs to start reading the history books and thinking with their brain, assuming they can find one.

Palm TX: First Impressions

This is my 5th Palm device since 1997. I've had a 512k Pilot Personal, a 4M Palm IIIx, a 16M Clié T625c and then a 64M Tungsten T3. The T3 I won in a competition (thanks Proporta!) but all the others I paid approximately £200 for, so I guess that is what I consider to be an acceptable price for a PDA. With all of the others this meant that I had to wait for the price to drop, but the TX started at this price. As recorded at Palm 24/7 (scroll down to the 'Palm Europe Trade-in Offer' article) I traded my Pilot Personal in so I got a very good price, but the Dixons airport stores are selling the TX for £195 and it is readily available online for around £210. Such is progress in electronics - I'm glad I don't have to try to make a living off hardware.
Right, on to those impressions...

• The screen is really nice, bright and clear.


• Graffiti 2 still sucks (or blows goats, depending on your idiom preferences) but recognition seems better than the T3


• I've seen all the posts from people moaning about the lack of a cradle.I have a drawer full of cradles that I have never used so I am very happy to have a cable in the box.


• Wi-Fi - just brilliant. Easy to configure, performance is fine, just works.


• MP3 player - pTunes is fine, no frills but perfectly functional.The TX appears as a mobile device in WMP 10 so getting music on and off the card is really easy. I've only got a 256Mb card but now I've confirmed that the TX can do the business as an MP3 player I'll be ordering something bigger!


• Compatibility seems ok. Just one of my favourite programs fails to work - the freeware currency converter 'Currency' causes a soft reset every time I try to run it.


• Outlook synchronisation didn't work. I got a load of OLERR: errors and the Calendar synch failed. This happened with my T3 too, and after trying the various things in Palm's knowledgebase I took their suggestion and gave my money to Chapura for PocketMirror. This is actually a pretty major flaw, and I think it is pathetic that Palm's suggestion when their software doesn't work is to buy someone else's - just fix it for Gods sake! I do have six years worth of data in my Calendar and if I cleaned it up the problem might go away, but PocketMirror and the Intellisync software that came with my T625C work fine on exactly the same Outlook data so it clearly isn't impossible to make it work if you know what you are doing.

Despite the Outlook hassles, overall I think I'd have to say that I'm pretty impressed with the TX. Of course I'm lucky that I'm not bothered by the T3 features that didn't make it to the TX. I never used the voice recorder, I just can't get agitated about the lack of an LED and I can live without a vibrating alarm. Others may feel differently, but for me the lack of a slider, Wi-Fi, longer battery life, non-volatile RAM and better screen are more than adequate compensation.
The final paragraph was going to read "This review written entirely on the palm using Graffiti 2 and posted using u*blog". Unfortunately, u*blog worked fine until I pressed the 'post' button, at which point it soft reset the TX. It doesn't have an export function, so the portion of the review that survived the crash (about 60% of it) had to be copied bit by bit (to keep under the clipboard limit) into Memos. Any suggestions for a Palm blogging tool that works on a TX?

fundaMentalists

Talking about possible future problems like climate change, loss of biological diversity and disease, Royal Society president Lord May says in a speech today

"Sadly, for many, the response is to retreat from complexity and difficulty by embracing the darkness of fundamentalist unreason. The Enlightenment's core values, which lie at the heart of the Royal Society - free, open, unpredjudiced, uninhibited questioning and enquiry; individual liberty; separation of church and state - are under serious threat from resurgent fundamentalism, West and East."

Amen to that, brother. (via the Register)

Another step towards Big Brother

Another excellent article at the Register. Technology is obviously going to make all sorts of things possible, but just because something can be done does not necessarily mean that it should be done. Dealing with untaxed and more seriously uninsured cars is obviously a good thing - uninsured drivers cause a lot of grief every year. But as we all know

Power corrupts - absolute power is kind of neat

or something like that. Technology or even legislation introduced for honourable reasons (look, I'm trying to give them the benefit of the doubt here, OK?) can later be used in less benign ways. It is really difficult to know where the line should be drawn but if we don't draw it somewhere, pretty soon we may have no say in the matter at all. At the very least there should be an open and informed debate about the price we are prepared to pay for security and law enforcement, and I don't see that debate happening at the moment.

Software companies are stupid

Mike Magee at the Inquirer has been chatting to some hardware guys - serious hardware guys, the one who design and make chips. He says that they are muttering that all the software indstry has done with the power that the chip manufacturers have given them is use it to allow them to make stupid software. I think they've got a point, but I'm not sure that the software companies are the villains here.
I'll use storage for the following argument, since it is easy to compare like with like - it is a lot harder for processors, although similar logic applies. I am old enough to remember when 2GB of storage took up the space of a large wardrobe and cost £100,000. I just checked and today 2GB of storage can be had for £0.61 as part of a 200GB disk, and if you put it in your wardrobe you'd probably lose it. At the time, as a programmer, I was paid about £8000 a year. On that basis, it was worth spending quite a lot of my time making my software as smart as possible if that saved hardware spend. 2GB of storage=12 man years of effort. I reckon an equivalent junior programmer today gets about £25,000 p.a. which makes 2GB of storage worth approximately 3 man minutes of effort. This fundamentally changes the economics of software development and means that the advances in hardware are just used in an attempt to do the same stuff more cheaply, rather than to innovate and really take advantage of what is possible.
To go back to a familiar theme for this blog, we once again see how a focus on price alone has negative consequences for the society and individuals alike. Just imagine what we could have achieved if we had decided to explore the possibilities of the computing power we now have - HAL 9000 could have been a reality in 2001. On second thoughts, perhaps that wouldn't have been such a great idea.
