sameAs.org is a great service on a number of different levels. It provides a much needed piece of Semantic Web infrastructure and it achieves that through a simple clean interface and API. You don’t even need to know anything about RDF to get value from the service. In short it’s one of those nice web services that do one thing and do it really well.

I use the service as a frequent example in my talks and training sessions on Linked Data. For example, while it’s useful to review techniques for linking together datasets, in practice you can achieve a lot by simply doing a series of look-ups against sameAs.org. I’ve had some happy experiences of discovering connections between datasets without having to do any manual linking.

More than a few times recently I’ve been thinking that it would be useful to repeat what Hugh Glaser and Ian Millard achieved with sameAs.org, but for a number of other common RDF predicates.

In my opinion there are a small number of general predicates that will act as the backbone for the web of data. At the head of the predicate long tail we’ll find properties like: owl:sameAs, but also useful properties like dc:subject, foaf:knows and foaf:primaryTopic.

The topic based predicates (dc:subject, foaf:primaryTopic, foaf:topic, et al) are particularly useful for discovering documents and material that relate to a specific resource. An index of these would be extremely useful for inter-linking between content from different news and media organisations for example. I’d envisage that “topicOf.org” might index a range of different topic related predicates and expose some useful discovery tools, relations and equivalencies. Dan Brickley has a nice diagram that shows how these different predicates inter-relate.

“topicOf” is currently top of my list of these predicate based services. But the same approach would work in other contexts. For example a service that indexed foaf:knows would be useful for social networking applications. But I think that this area is already well-served by existing services already. But what about:

• “reviewsOf.org” — find reviews about a specific resource. I believe Tom Heath has thought about doing something like with for Revyu
• “depictionsOf.org” — find pictures of a specific resource (foaf:depiction), e.g. person, place or thing (and reliably, not like the Flickr Wrapper)
• “madeBy.org”> — find documents, photos, or other resources that were made by a particular person (dc:creator, foaf:maker)

I can think of all sorts of useful purposes for these services. I also think that they could offer additional ways of engaging with the broader developer community and getting them to buy into the Linked Data vision.

Anyone want to have a crack at implementing some of these?

No really.

I went to collect a book I had reserved at my local Wolverhampton Library, and as I had the item issued, I was offered a free tea bag.

Bemused; politely; I said no, thank you, I don’t drink tea.

P.S. Wolverhampton Libraries, why can’t I reserve a book on-line if it is NOT on loan? quite often I would prefer you to send the book to my local library if it is in the Central Library on the shelf. And I know your system could do it!

Have started moving the stuff for my Gradino blog engine (this) over to KnowledgeForge.

Following a tweeted link to “the funniest comment thread ever”, I spent a few minutes laughing at the expense of hundreds of confused Facebookers. They had been leaving comments on a ReadWriteWeb blog post about a recent venture with AOL to share login access. It took me a few seconds to get the joke: there were scores of comments like:

The new facebook sucks> NOW LET ME IN.

and

please give me back the old facebook login this is crazy……………..

and

All I want to do is log in, this sucks!!!!!!!!!!!!!!!!!1

One of the RWW team confirmed in the comment thread that these were genuine: that the traffic was coming from Google referrals using search terms like “facebook login”.

Hundreds of Facebook users googled for the Facebook login page and, landing on RWW’s post, left comments expressing how frustrated they were with the new layout and their inability to login.

Even after RWW put up the following message in the post, people continued to complain:

Dear visitors from Google. This site is not Facebook. This is a website called ReadWriteWeb that reports on news about Facebook and other Internet services. You can however click here and become a Fan of ReadWriteWeb on Facebook, to receive our updates and learn more about the Internet. To access Facebook right now, click here. For future reference, type “facebook.com” into your browser address bar or enter “facebook” into Google and click on the first result. We recommend that you then save Facebook as a bookmark in your browser.

This is hugely funny, until it becomes sad.

After a few pages of befuddled (and often abusive) lost Facebookers, the comments started to contain more genuine commenters observing their enjoyment of the confusion, trollbaiting, and teasing the confused crowd. Some were genuinely clever (*likes*), but many followed the basic forum trajectory of ridicule.

What struck me, however, was my own ignorance in this. I had no idea just how many people rely on services like Facebook who don’t have even a basic grasp of how they’re doing it. The fundamental “browser” metaphor makes it pretty clear that you need to “be” a certain place in order for things to work the way you expect them to. Even without some form of teaching, that level seems too obvious not to get.

But it clearly isn’t. The implications are potentially worrying. Hundreds of people were able to leave comments on a site that wasn’t their destination stating their outrage and confusion. One commentator made a good point about them being lucky that ReadWriteWeb is a relatively benign place to accidentally land; but what if this were a post about Wells Fargo or a health insurance company?

Like many near-geeks, I’ve helped friends and family on technical issues in the past, and there is a level of assessment involved: Where do I need to start to get them using this? But nothing prepared me for this.

This may be hilariously funny, and it might be disconcerting, but it’s most definitely a lesson.

“Love the Lord your God with all your heart and with all your soul and with all your mind.’ 38This is the first and greatest commandment. 39And the second is like it: ‘Love your neighbor as yourself.’ 40All the Law and the Prophets hang on these two commandments.” Matthew 22:37-40

I have been struck, at various times over the years, that the Church isn’t all it’s cut out to be. I mean this almost literally. I’m thinking of the “church” as a pattern—like a tailor uses—of how to live, just now. It’s not that it can’t be altered, embellished, customised, and stretched—these are right and useful. It’s more that the pattern itself is often distorted, or badly copied.

What we know of Jesus’ life is full of relationships, and the “Kingdom of God” he talks about is built through the interactions of parts of his “body”—the people of the church. There are whole bunches of metaphors around who we are and what we’re called, but the prime message is about getting along and looking after one another. His definition of who’s in, and who’s out isn’t particularly clear—something I’m sure will raise some eyebrows—and included prostitutes, dodgy businessmen, lawyers and murderers. The only group he seems to have no time for are the religious.

Holding a weekly service has been the definition of church for a very long time, especially among protestant Christians and especially in the West.  It seems that often church means attendance at a weekly service. It has become part of our language:

ʻI have church on a Sunday,ʼ
ʼIʼm off to church,ʼ
ʻWeʼll have a big roast after church,ʼ

In the new Testament, the word most commonly used for church is ecclesia, which means: ʻa called-out company’—but for what have we been called out?

A couple years ago, I was thinking of a project our “church” had been involved in: the Noise. The Noise is an annual event which brings together literally scores of villagers to help one another out in practical ways. Over the past years, it’s tackled elderly folks’ gardens, public paths, school buildings, and family’s houses.

As something to look forward to each year, it’s hard to beat. I cannot think of a single place where I’ve seen young people and very old people and everyone in between helping out and simply sharing a common love. Needs are met, relationships forged (and mended) and people of all ages work, and laugh, and eat together. It’s a picture, to me, of what I think I mean by “community”.

But, what struck me was the idea that a noise only lasts for a moment and quickly fades. It also lead me to think that the church wasn’t being church, except at this time of year. Please understand, I don’t mean that nothing good happened all year, but that something of the essence of a love-driven community was only really experienced during these few, summer days.

Eventually, I started thinking that instead of a “project”, perhaps we should think in terms of a framework, or a network, or another platform for experiencing and sharing this love actively. I called the initiative “resound”—a noise that keeps going.

What follows are some of my thoughts, slightly updated, from the time.

Resound’s principles include:

• Worship of God through works of service
• Active Love
• Network of Relationships / Community
• Every-member ministry
• Church outside of church.

Worship often takes the form of singing or declaring love and worth to God. I believe that all our actions can be worship. We have been called to be “living sacrifices” in Romans 12. Hebrews 13:15-16 ties the sacrifice of praise from out mouths with doing good:

ʼ15 Through Jesus, therefore, let us continually offer to God a sacrifice of praise—the fruit of lips that confess his name. 16 And do not forget to do good and to share with others, for with such sacrifices God is pleased.ʼ

Active love or ʻlove in actionʼ is a primary facet of Christianity itself. Jesus repeatedly challenged lip-service and religiosity and his teachings are littered with examples of a love so deeply held that it motivates action. We read (1 John 3:17-18):

ʻ17 This is how we know what love is: Jesus Christ laid down his life for us. And we ought to lay down our lives for our brothers. If anyone has material possessions and sees his brother in need but has no pity on him, how can the love of God be in him? 18 Dear children, let us not love with words or tongue but with actions and in truth.ʼ

We are also told that if someone needs food and we say: ʻBe blessed with food,ʼ but do not feed him, we are uncharitable. Relationships form the basis of our faith in Jesus.

Christianity is described as a relationship with God through Jesus. Fellowship plays a vital role in humanity. We use language to interact, we are capable of loving without reward, and we are born into families which (ideally) teach us to get along. I do not believe that all of this charity, love, and fellowship is to be a reward for ʻbecoming a Christian,ʼ. It should, rather, be a consequence of the Love God has so freely given us.

I believe that the Church is present and active in the community, and that its ʻneighboursʼ are a huge part of its life. In traditional weekly services, there are several members whose roles are obvious (preacher, singers, musicians, and—unfortunately —the technical team) and those whose role is needed but less obvious (deacons, elders, and those who count offerings). For the most part, however, the church comprises people whose role is not so much unobvious as undefined. There is no precedent in the Bible for people to have no active role in the church. If this means that there is only so much that can be done in a Sunday service, perhaps there may be more outside this which requires their attention. Many people who cannot preach can paint. Many who cannot sing can scrape old paint off an elderly ladyʼs house. Resound offers a framework for more peopleʼs ministry. It should offer support to natural village networkers as well as to handy(wo)men.

As part of being ʻin ministryʼ through doing practical needs and building relationships, Church is taken outside the church. I believe that our acts of worshipful service are as spiritually significant as the songs sung and prayers proclaimed within the walls of a special building. Without discounting the need and importance of worshipping and gathering together, Resound offers a chance to put principles into action and let the Spirit free to minister. If we find our neighbours difficult to love and serve, surely we will not find anyone easier.

I wanted to copy some files from one directory to another while I am working on my wordpress blog-in-blog plugin.  Basically I needed to copy the files checked out from svn, from the working directory, to the root of the web directory on my local machine.

Feature requirements:

• Should only move a file if it has been edited. (we assume that the filesize will have changed by at least 1 byte!)
• Should not just sit there copying all the time.
• Should find out about all files in the specified directory.
• Should report when it updated the file and which file was updated
• First run should copy all files to the destination directory. (assumes I have updated my working copy from svn)

So after several attempts, here is a more polished version which stores the filename and the last size of the file in a ‘bash hash’. OK bash doesn’t have hashes (mores the pity) but reading around on the web I found this post with a comment from Scott Mcdermott which does the job nicely (once I had stripped offending characters from the file names).

So here is the full code of the deployment assistant:

#!/bin/bash

if [ -z $1 ]
then
	echo "usage$  $0 "
	exit 1

hash_insert ()
{
	local name=$1 key=$2 val=$3
	eval __hash_${name}_${key}=$val
}

hash_find ()
{
	local name=$1 key=$2
	local var=__hash_${name}_${key}
	echo -n ${!var}
}

while true
do
	for FILE in $FILENAMES
	do
		FILESIZE=$(stat -c%s "$FILE")

		#tidy up file to avoid problems in variable name
		FILE=`basename $FILE`

		#echo "filesize:"$FILESIZE

		if [ "$FILESIZE" != "$LASTFILESIZE" ]
		then

I’m not in the least bit excited about the iPad, and it seems I’m not alone. The mood seems to have changed since before the launch, with countless tech journalists previously falling over themselves to declare tablets the next big thing. (Thankfully Rory Cellan-Jones from the BBC was more measured, focusing on personal projectors as a more exciting development). The mood since is considerably more downbeat, and I think more realistic.

I may be missing some crucial usage context that reveals the killer characteristics of the iPad, but I’ve tried really hard and still nothing. There are many obvious practical issues with the device:

• it’s too big for a pocket, but not sufficiently more useful than an iPhone or an HTC Hero.
• it’s about the same size as a compact laptop, but with less scope for comfortable rapid input.
• it’s probably too big to cradle comfortably in my hand for prolonged periods, and sitting with one ankle on the other knee is not always practical.

The only scenarios I can conjure up where I could imagine using the device are:

• showing people my holiday photos.
• reviewing design proofs without needing to print them out.

Neither of these, or even both, are very compelling at all. TVs are getting good for viewing photos, by including e.g. an SD card slot, and rumours of the death of paper are greatly exagerated.

Perhaps the most annoying thing about the scenarios used to promote the device is the one about the San Francisco to Tokyo flight, watching video all the way without running out of battery. Any airline with planes worth boarding has personal video screens. I don’t want to bring my own. I’d rather use the space to carry a decent pair of noise-canceling headphones, which I’m sure increase my enjoyment of onboard media far more than a little bit of extra screen real estate. The development I want to see is not a new device that I have to prop on the flimsy airline table, hold tight when we hit some turbulence, and stow away when my food arrives, but the capability to connect my own device to the in-built screen via USB or Bluetooth. Even a bare USB port with power but no connectivity would be a start, allowing me to run low-powered devices (that I already own) during long flights.

OK, so the flight reference is just a touchstone for how long the device can run without mains power, but I think it demonstrates a lack of grounding of the device in realistic scenarios.

Any new device has to have two key characteristics these days for me to get excited: interoperability and convergence. The iPad seems to have very little of either. You could argue that it offers some convergence between smartphones and e-readers, but that’s about as exciting as convergence between a smartphone and a wall clock.

I’m left wondering what the iPad is competing against? I’m guessing it’s paper, whether that’s in the form of a book, brochure, newspaper, restaurant menu or whatever. Unfortunately for Apple, paper is pretty well suited to each of these, especially when you introduce bath water, the risk of theft, or just ketchup, into the equation. Perhaps this is the end of electronic picture frames as dedicated device? Probably about time. Maybe the iPad will make an excellent Spotify console for the living room. Who knows? Whatever happens I can’t see this becoming a mass-market product worthy of even a fraction of the hype.

Where I wish that Apple had expended their creative talent was in addressing the power issue. Not in making sure I could watch 10 hours of back to back video, but in enabling me to spend that energy in whatever way I choose, powering whichever device I choose. It drives me crazy that I carry several batteries around, and short of running my phone off my laptop via USB there is no interoperability between these power sources. If Apple could produce a universal power supply that was sleek, sexy, efficient and interoperable, then I would be interested. Sadly this doesn’t seem to be the way.

The Talis offices, for the past few weeks, have been awash with geeky excitement—that kind of near giddy excitement that comes with eager expectation. We’ve all been waiting for something important.

For some, this was no doubt augmented with the announcement of Steve’s new iPad; but that’s not what’s gotten us all worked up.

For months, we’ve been looking forward to the launch of data.gov.uk; and last week, the wraps finally came off. The official press release put it:

A major new website has been launched to the public which gives anyone who wants to use it unprecedented and free access to government data in one place.

This doesn’t quite capture the coolness of the launch, for me. Yes, it’s a major new website, and it’s point is to publish information. But, the exciting thing is that this information is being published as data: data that can be used, reused, remixed and enriched. Sir Tim Berners-Lee’s perspective was more exciting:

Making public data available for re-use is about increasing accountability and transparency and letting people create new, innovative ways of using it. Government data should be a public resource. By releasing it, we can unlock new ideas for delivering public services, help communities and society work better, and let talented entrepreneurs and engineers create new businesses and services.

The point is that this public resource is finally getting a home on the web, and an infrastructure to make it not just available, but useful.

The exceptional team behind data.gov.uk have striven to adhere to web standards in its production: including Linked Data as a priority, as Professor Nigel Shadbolt explained:

We are also going to increase the use of ‘Linked Data’ standards, which allows people to provide data in a way that is as flexible and easy-to-use as possible.

Back in November, Leigh Dodds wrote a post explaining how we’ve been involved, and there’s an official Talis Platform press release too. Basically, we’ve been working with the data.gov.uk team to help with the Linked Data part of the site—hosting the SPARQL endpoints and providing consultancy and training, for example.

I can confidently say that we’re very proud of data.gov.uk, the team behind it, and our involvement with it. We’re excited by the prospect of this data being used as raw material for clever people to make interesting, useful, even world-changing things with it. We’ve seen the beginnings and proof-of-concept projects already.

Now comes the really exciting stuff. What are you going to build?
