Lisp with Java


I was very pleased with myself for finding Armed Bear Common Lisp; you've gotta love that name. You get a cool editor as well!! For someone like me who works in a mainly Java shop the excellent looking integration of Lisp and Java is cool and potentially very useful for prototyping (I wonder if Bill Clementson knowws about this?). (I'm also rather more attracted to building GUI's in Swing as Lisp is has so many different GUI libraries and many are rudimentary, only run on some platforms etc.)

A bit more research brought up a Java Foreign Language Interface for Common Lisp and a Lisp-friendly interface to Java Servlets by Rich Hickey - both look good.

Then it turns out that Lispmeister mentioned the latter 2 over 2 months ago and I missed it:Lispmeister.com : Lisplets

More to play with!!

PS: Yes, Bill Clementson does know about these !! Article in June or so; I wonder if he has done any more with any of them ?

More on DSL's and Lisp


Bill Clementson's Blog: DSL and Metaprogramming Resources

An eventful year for Lisp


I started looking at Lisp in the middle of the year, after a single course on it way back on my BSc course. I discovered that there was a lot more to it than I thought. This timeline is intersting though, as it shows a lot of progress has been made, just this year.ALU Wiki : 2004 Lisp Timeline

My sense is that there is a lot of activity around Lisp at present. I certainly feel that the renaissance of Virtual Machines and the rise of Domain Specific Languages is bringing the computer world back towards Lisp.

Cringley on the IBM PC/Lenovo deal


This analysis certainly makes more sense than IBM buying Apple!
PBS | I, Cringely . Archived Column: "Winners in this deal are IBM, Lenovo, AMD, and Dell. Lenovo instantly doubles its market share. AMD eats away just a little bit more at Intel's power base. Dell, as the true PC market leader, will rely on its lower overhead to further hurt HP.

Losers in the deal are HP, Intel, and Sun. Especially Sun. Those guys are in trouble."

Successful Lisp arrives


My copy has arrived!Lispmeister.com : Buy "Successful Lisp" at amazon.com

It is in beautiful condition, the cover looks great. Opening it up is a joy: the pages are crisp and new, the font lovely.

My only gripe? Each right-hand page has a tiny left-hand margin and a big right-hand one. I can see the spine coming under a lot of pressure as I struggle to see the first word of each line.

I ordered mine early from Booksurge.com. No complaints about speed of delivery, but the web store experience was scary, and response from customer service was non-existent. When I input all the details and confirmed the order, up popped a record of the transaction with a blank order number, and a list of things which I hadn't ordered, and the wrong total in dollars !!! Eeek. Phone number given on the site didn't work - eeek! Three e-mails to the address given - no response at all. Ohno!! I was getting a mite agitated I can tell you.

I was somewhat comforted when VISA confirmed the correct amount for Successful Lisp had actually been deducted ( and not the bogus amount) and that there were no other unaccounted for transactions.

Anyway, I am pretty much convinced I have not been phished and the book is here.

One last thing: David Lamkins ( author) should refrain from dyeing his hair (IMHO) !!

Model Transformation and Eclipse


Something new from IBM:alphaWorks : Model Transformation Framework: "What is the Model Transformation Framework?
The Model Transformation Framework (MTF) is a set of tools that helps developers make comparisons, check consistency, and implement transformations between Eclipse Modeling Framework (EMF) models. The framework also supports persistence of a record of what was mapped to what by the transformation; this record can be used to support round-tripping, reconciliation of changes, or display of the results to a user."

If the models can be expressed in EMF then they can be transformed.

Lisp and Domain Specific Languages


Bill Clementson's Blog: "Forget syntax, forget library availability - the 'Lisp Difference' is that it allows you to create whatever domain-specific language you need for the problem space that you're working in."

Doesn't sound like Microsoft's DSL Workbench - still nothing wrong with that!!

I think "to reduce costs" might have been more honest! If you want to reflect a broader geography, you spread out. But no doubt that reduces management control, economies of scale or something.

Jonathan Schwartz speak with fork tongue?


I listened to the Gillmor Gang podcast for the 25th November (trendy , heh?). Mr Schwartz was that and came over as witty and made some insightful comments. He also made assertions about Red Hat which Steve G and co. never really called him on. And he kept talking about "Open", not alsways making clear which concept he was on about -Open Source or Open Standards (can I have both please?)

Now this:Slashdot | Sun's COO Pretends Linux Belongs To Red Hat

I hope Steve Gillmor asks Jonathan to back up some of his assertions: for instance, which benchmarks are showing Solaris trouncing "Red Hat's Linux" ?

IP Policy : the tyranny of the lobbyists


Democracy isn't just about everyone being able to vote. Who influences and drafts legislation? Who gets to sit on influential bodies endorsed by a government. We have a once every 4 or 5 year "nuclear option" to keep our elected representatives in-line - big industry has continual, well-financed influence. And they are using it: FT.com / Comment & analysis / Columnists - James Boyle: A natural experiment:

"So how do we decide the ground-rules of the information age? Representatives of interested industries come to regulators and ask for another heaping slice of monopoly rent in the form of an intellectual property right. They have doom-laden predictions, they have anecdotes, carefully selected to pluck the heartstrings of legislators, they have celebrities who testify - often incoherently, but with palpable charisma - and they have very, very simple economic models.

A flurry of books on Lisp


For a supposedly dead language (ducks behind cover), Lips is gettng a fair number of new books:



"Hackers and Painters" has some Lisp references too.

Talking of Paul Graham, an update to "On Lisp" would be great. "On Lisp" is a great example of going beyond an intro book - it really shows the power of the language by going beyond the simple cases. I'd like to see other books that go into GUI, database etc. at a more detailed level. Of course, a disadvantage of Lisp (and Smalltalk) is tha therre are many ways to skin those Cats, so a book of contributions covering the most popular alternatives would be great.

What about Smalltalk? There are some fairly recent Squeak books, but perhaps there will be more along in a while.

Great hackers revisited


This article reflects many of my opinions about Paul Grahams article:Great Hacker != Great Hire

I too enjoyed the essay, but I too rankled at some of the strictures (Obviously I am not a great hacker!)

I really don't understand the part about not wanting to work on customer stuff - ultimately that IS what matters. The number of jobs you can do without pesky users is severely limited - back to academia ?

Also, team work is just so important; are there pretty great hackers who are more productive than most, but aren't prima donnas ?

What war on terror

NO, NO, NO, John. That is the Bush lie. They have given their lives to an obscure, oil-drenched Texas family feud, to a personal vendetta that has nothing to do with the real security of the United States and in fact is making us less secure by breeding a million widows and orphans who blame us for their misfortunes and will spend the rest of their lives trying to get back at us.

The Real War on Terror is tracking down Osama, rooting out the entrenched hate-mongers in our 'allies', Pakistan and Saudi Arabia, stopping the massacres in Africa, finding the Anthrax killer, and getting real about protecting our borders, airports and container ports."

When to update hardware


Ted has an eye for good looking hardware:Ted Leung on the air : Lunchbox multiprocessor

The thought occurred to me though, that I have not upgraded my hardware for a while either. Perhaps this is a trend? I did build myself a box a few months ago, but it was low-tech: the aim was a small, cheap and quiet box. In fact it is a Duron processor, which is fine for Web usage, a bit slow for starting up the word processor.

If I am honest it was the kids games that used to drive most upgrades, so either they are more diligent with school work(!) or advances in games no longer requires increases in hardware power.

Is this "The Innovator's Dilemna" in practice? If PC manufacturers focus on more an more power, will they be beaten by other who focus on other facets? For instance, beautiful design, size, power , noise ......... Perhaps Ted's choice has power and these other factors!

OCL: " The semantics of OCL is unclear in many places, and there are likely many pitfalls in mapping it to a well-founded language like PVS. However, the potential for making a contribution to the UML development and to our understanding of OCL is great"
Scott Rosenberg's Links & Comment: "I can't imagine anyone watching Miller's frothing speech and feeling reassured about the direction Bush is taking us. It was an outburst of intimidation, intended to cow. Dave Winer heard the jackboots behind it: 'Why was the Miller speech so scary? Answer -- you're next. That's what Miller was saying. After this election we put on the brown shirts.' That may be a little over the top, but the fact that's it's only a little over the top is itself chilling."

And: ' "Today, at the same time young Americans are dying in the sands of Iraq and the mountains of Afghanistan, our nation is being torn apart and made weaker because of the Democrats' manic obsession to bring down our commander in chief."

Strip this of its spin and modifiers and what Miller is saying is, "While Americans are dying, the opposition party is trying to win the election, and that hurts the nation." '

The Fnordistan Department of Software Engineering ? What Java Owes to Smalltalk

More regrets



The Fnordistan Department of Software Engineering ? What Java Owes to Smalltalk
:

That’s the sort of thing I didn’t really notice until I started working with Smalltalk. Now I shake my head and wonder how much better life would be if it had been Smalltalk rather than Sun’s Java that had been poised to catch the wave in the 90s.

Forget the particular languages mentioned here (though I do agree), there seems to be a lot of feeling that things haven't improved in the area of language design. I see Python, Groovy, Ruby etc. restating older things, almost looking over the morrass of C, C++, Java, C# et al which form a tar pit between now and then. Of course other languages like Smalltalk, Lisp etc. have waded through; but are they prepared to move forwards themselves ?

Return of Java


The article refernced here is wierd:Slashdot | The "Return" of Java Discussed

Slashdot asks whether Java has been anywhere, but I wonder what makes us think it is getting renwed attention. The article cites:


  • Jon Schwartz of Sun saying Java helps keep the cost of substitution low: cost of substitution is just part of the costs, and anyway you can only substitute vanilla installs - must Java apps sit on app servers and you certainly can't easily substitute those
  • VCs think games can be written in it

  • I'm convinced !!

More heresy!


IT industry warned over wasted money | The Register : "It [the survey] highlights the need for the industry to deliver tangible benefits, focus on selling practical solutions not technology for technology's sake and most importantly to improve after sales customer service. With the customer in mind, it is also important for us to focus on integrating new technologies with existing systems and not automatically adopt the 'rip out and replace' mindset."

So why does the industry get away with this approach? I think it may partly be because elements within the customers also like to focus on technology, haven't thought through what the business wants etc.

Treating workers well increases productivity?

Dangerous and subversive ideas: IT company gives workers free beer - wins award | The Register : "n fact, AGI spends around $1m a year on freebies and perks for staff, according to the Detroit Free Press.

Spotted in Bill Clementson's blog quotes from Paull Graham's Hackers and Painters, including this:
"A programming language is for thinking of programs, not for expressing programs you've already thought of. It should be a pencil, not a pen. Static typing would be a fine idea if people actually did write programs the way they taught me to in college. But that's not how any of the hackers I know write programs. We need a language that lets us scribble and smudge and smear, not a language where you have to sit with a teacup of types balanced on your knee and make polite conversation with a strict old aunt of a compiler."

Ancient Greece vs. Soviet Russia


Spotted in David Buck - Blog :


There are two conflicting forces driving software development. The first force tries to help developers by giving them the tools and environments that let them do anything they need to do to solve the problem at hand. They give the programmer the freedom to create whatever solutions they deem necessary.

......

Do restrictions in the environment help? I believe that they only help a little and usually cause more harm than it's worth. They increase finger typing, hinder productivity, slow down development, increase refactoring efforts, and decrease code readability

Re: More Alan Kay notice
Spotted in Smalltalk Tidbits, Industry Rants :
But late-bound has some deeper and more profound properties that include abilities to actually change the both the structure and metastructure of the language itself. Thus an important new idea can be assimilated into the constantly evolving process that is the system.

Another aspect of late-binding is the ability to change one's mind about already instantiated structures that are already doing work. These can be changed automatically on the fly without harming the work they are already doing.

Good thinking, as usual, from Dan:
Software That Lasts 200 Years

One thing I have been struck by recently, is how many times we reinvent the wheel ; we produce a new platform, in a new technology ( including hardware/OD platform), with a new interface. However, to the application the new features are not that great - perhaps there are a few new things, just enough to warrant a re-write.

But surely, there is enough demand for new software that we can still employ our current developers and perhaps more. Of course, they might be specialists in other areas who can develop on the longer lasting platforms.

Productivity quotes


I hadn't seen these before ( must have been prior to my taking another look at Smalltalk):
Smalltalk Tidbits, Industry Rants: Experts say Smalltalk is better:

"Kent Beck (Mr XP) said (at ESUG 1999 in Ghent) that, 'I program at a third of my Smalltalk speed in Java.'

Bran Selic (RealTime UML guru, built the tool that is now the RT part of Rational Rose) said (at UML 2000 in York) that, 'I was sorry to see Smalltalk lose out to Java because Smalltalk was the only language in which I noticed a real difference in my productivity'."

I know one of these gentlemen - I must get his latest thoughts on the matter......

uhoh.... be very afraid!

Paul Graham's sneaky strategic advantage


And here is the Paul Graham article referred to: Beating the Averages: "Another unusual thing about this software was that it was written primarily in a programming language called Lisp. It was one of the first big end-user applications to be written in Lisp, which up till then had been used mostly in universities and research labs. Lisp gave us a great advantage over competitors using less powerful languages."

Strategic advantage and keeping quiet about it


Here is the quote I referred to earlier:: ONLamp.com: The Pragmatic Programmers Interview: "Ultimately, it comes down to ease of expression. If I can express myself in code at a level closer to the problem domain, then I'm going to be more effective, and my code is likely to be easier to maintain and extend. Paul Graham makes a big deal out of the way Lisp helped him while building the software that became Yahoo Stores, and he's right. These languages, applied properly, are a strategic advantage. I know some companies are using them with great success. And you know -- they're keeping quiet about it."

Is this the big secret?


I will dig out the refernce, but I saw a blog entry a while back talking about how vaiuos small companies are using certain languages as a competitive example, and they are keeping quiet about it !! I remember it cited Paul Graham's LISP implementation of Yahoo stores(note find pointer to his essay).

Here James Robertson points to a very important application ofthe experiments I have been doing:Smalltalk Tidbits, Industry Rants: How dynamic is dynamic?: "I can't imagine trying to manage a server without this capability. This blog hasn't been taken down in months, but I've made major changes to the underlying code base. How? By making use of the facility keith mentions, that's how."

This is an advantage I hadn't thought of before - my thoughts were on much smaller timespan benefits for client apps. Coolll!!

How dynamic is Python?


OK, this lunchtimes experiment was Python. Created a class and produced an instance, then modified the class by adding a method - the instance did not have this method available. However, a new instance with the new class did.

I have no idea whether ths old class and its instances stay around, disappear with gabage collection etc.

How dynamic is your (programming) language?


I'm doing some experiments on changing classes at runtime without affecting existing instances.

With Smalltalk ( at least with Visualworks) this was a breeze: added the code for a variable, accepted it and, hey presto, any inspector open on an instance got a new variable field set to nil.

Even tried Lisp, which I haven't used for $%$ years. Why ? 'Cos you can do anything in Lisp can't you, especially this dynamics stuff? Well, I tried CLISP first, and guess what ? A redefinition to add a new slot invalidated existing instances ( or so the message said). Not taking no for an answer I accessed an old instance and crashed the whole environment.

Now it has to be said that, from the docs I have read, I wasn't sure what the behaviour should have been. Finally, I found a doc which seemed to be adamant that it should have worked. So I tried the free version of Franz' Allegro Lisp..... and it worked.

What next? Well, what can other languages such as Python and Java do in this regard? Also try to be more scientific with Lisp and Smalltalk: add/remove variables, add/remove methods, add/remove supportable etc.

I wish Dave would take the time to clarify what the facts are. Given the way this farce was announced, muttered about, rescued, it is hardly surprising that there is some confusion.

I'd like to see a sober setting out of the facts that show why the end of the service had to be announced, before a rescue package could be put together.

Another fact of importance would be,"when did the users get informed that they were being hosted by Dave, rather than Userland?" I think this escaped a lot of people.

Grady on UML "vs" DSL


What a guy !! Grady Booch on developerWorks : Blogs: "However, I think, as does Simon, that Keith misses the point when he distinguishes DSLs as something totally different from the UML. The last thing the world needs is yet another (non-open standard) programming model or language injected in an already complex space. Our experience has shown that domain-specific design and architectural patterns specified can (and should be) expressed in the very same language that one may use on a whiteboard or napkin, namely, the UML. "

UML & DSL: Simon says....


I find myself in agreement with the following points:developerWorks : Blogs:
My position is that the creation of domain specific languages that do not seamlessly support the ability to transform information along the refinement scale are not helpful to us. So, for example, a component designer that is a stand alone tool unconnected to the class designer that provides the next logical level of refinement (classes being used to construct components) is a pot hole in the road from concept to actual implementation. Now, this is not as I have said to indicate that domain specific languages are bad, just that many of us in this industry love to create new languages be they graphical, textual or conceptual. We have to beware of the tendency to build these disjoint languages that force the user to keep stopping and jumping across another gap.
My summary: present different views to different users, but in a way which keeps transformations (including mental ones) easy (e.g. all views based on common metamodel)


Now, does the UML help us in this? Well, actually as it stands no, it has many pot holes all of it’s own! But, one way to look at the UML is a pre-existing set of domain specific languages, with at least small and well understood gaps between them. For example most everyone is familiar with the class model, the component model, the state machine model – all of these can be treated as sub-languages, and have been successfully applied in projects.

My summary: common set of concepts which can be tailored


Now, the danger is then to say that the UML is enough surely for any problem (got a hammer here – anyone got a nail?). Well therein lies a big, big hole waiting for the unwary. The UML is a general purpose language, like English and as such can be vague in a particular domain, so we have created specific usages of the English language for engineering or science, even standardized the meanings of terms for defining specifications (RFC 2119). In this regard it is clear that the UML needs to have particular usage patterns documented as sub-languages, or domain specific usage.


But then, there are simply concepts in use today that do not map well to any UML sub-language or usage pattern. Well, the OMG has already thought of that and provided the Meta-Object Facility (MOF) which is the underlying language used to construct the UML – making MOF a domain specific language for constructing domain specific languages? Here at IBM the open source Eclipse Modeling Framework implements the MOF specification and provides both run time capabilities and tools for defining new modeling languages (and you can see examples in the XML Schema Tooling on eclipse.org).

My summary: UML can be extended, and if that isn't enough then new dialects based on MOF can be built. Still the transformation gap is small.

Anyone seen a scenario mapped out in the two approaches? When the terms and concepts seem so slippery a practical example always helps.

Quick now, what IS the difference between UML and DSL?


The DSL, MDA, UML thing again... | Lambda the Ultimate

Can you have one metamodel across differnet domains that, nonetheless can be tailored? If you do, can the transformation be small variations on one another ? Can we ever expect them to be totally automated? (no) What is a domain anyway : industry, level of abstraction?

This seems to be one of those arguments where the terms involved remain unresolved and ambiguous (at least to me)

High Court move over police chief


BBC NEWS | UK | High Court move over police chief

Apart from the details of this case, how do we come by such badly written laws here in the UK? Why do we write a law which apparently gives the Home Secretary the power to suspend a Chief Constable, but for some reason this has to be actinide through some other body such as the local Police Authority ?

Either we let local areas have authority or we don't. If we want to allow the case where the Home Secretary can ride rough-shod over this pretense at autonomy, then he should do the dismissing and inform the Police Authority.

This is a horrible fudge of a law, and I am glad it is coming back to irritate the politicians who regularly enact Laws with so little principle behind them. Actually, I hope it does more than irritate them!!

London-Brighton Bike Ride


What am I thinking of? Forgot to Blog about my cycling epic!

Last Sunday, 20th June, I and 26,999 other "cyclists" bowled out of London on a nice sunny Sunday. We were about an hour late starting due to our transport , but also because of the huge queue to get the start/finish card stamped.

Cycling as a team proved almost impossible, but other tthan that and buses actually wanting to use the bus lane everything was fine.

Out in the country everything was lovely except hills on narrow lanes where most people got off to walk and blocked the road completely.

My legs got tired at about 40 miles - took a break and also sorted out why my new Camelbak water carrier was giving out so little water(kink in pipe).

At about 50 miles you hit the only real hill on the course, but it is nasty - again the road is quite narrow, so most people walk. The experts ( and people with proper clips on their pedals) are determined to cycle up; with a lot of tired people this is a recipe for disater. Oh, and it started raining big time, and Brighton being by the sea, the wind was cold.

The next 4 miles to the sea front were awful: rain, wind, large roads where the police bunch the cyclists up to let them cross - it took over an hour to do this.

By the end, I was really cold - my teamates looked even worse and were shaking.

Then we got a lift back to Winchester.

So, for next year, I'm looking for a cycling challenge which is far less crowded : any ideas ?

Think tanks lack transparency


Deltoid : When Think Tanks Attack: " And the Albion Monitor writes:

[Citizens for a Sound Economy] is just one of several tax-exempt orgs that have divided over $750,000 from Microsoft and waxed in outrage over the proposed breakup of the software giant. Other beneficiaries include the Cato Institute, Heritage Foundation, National Taxpayers Union, and about a dozen more obscure names such as Citizens Against Government Waste, Citizens for a Sound Economy, the Small Business Survival Committee, the Independent Institute, Americans for Technology Leadership, and the Association for Competitive Technology.

Together the groups wage a disinformation campaign almost identical to the attempt to debunk global warming waged by Big Oil that we described in a 404 report two years ago. The strategy requires discrediting Microsoft critics while building a sham Â?grassrootsÂ? movement in support of the corporation.

More finding LISP


I find myself wondering about LISP as well as Preston:Preston L. Bannister ? Finding Lisp.

But I'm not sure how he squares these two paragraphs:

  • "Both were written using UCI Lisp. [....] The folks in the Ada programming environment project generated an Ada parser, interpreter, compiler, and integrated editor for a subset of Ada in a remarkably small amount of time. This was only possible by leveraging off the Lisp environment. " AND
  • " In fact the combination of Java and XML covers much the same ground"

I should have thought the ADA environment probably used features such as LISP macros etc. ; how do Java and XML help there?

2004/06/22

Finding Lisp: "One of the things that struck me is that more than any other language, Lisp, because of lambda calculus as well as the convenient notation provided by s-expressions, lends itself to source-level transformations. Macros are the most obvious user-level expression of this capability, but Lisp compilers also make very heavy use of this capability to reshape code symbolically before they actually start generating object code."

Iraq - al-Qaeda


FT.com / Comment & analysis / Editorial comment:"The Bush administration has misled the American people. It has isolated the US, as American diplomats and commanders pointed out this week. And its bungling in Iraq has given new and terrifying life to the cult of death sponsored by Osama bin Laden. Above all, it inspires little confidence it is capable of defeating the spreading al-Qaeda franchise, which always was the clear and present danger."

Industry Best Practice


I am not qualified to assess Paul Graham's comments about the advantages of Lisp. For instance, what about Lisp and database access, which I have discussed elsewhere. But his point about the risk aversion of people in LargeCos is great:Revenge of the Nerds: "This is the kind of possibility that the pointy-haired boss doesn't even want to think about. And so most of them don't. Because, you know, when it comes down to it, the pointy-haired boss doesn't mind if his company gets their ass kicked, so long as no one can prove it's his fault. The safest plan for him personally is to stick close to the center of the herd.

Within large organizations, the phrase used to describe this approach is 'industry best practice.' Its purpose is to shield the pointy-haired boss from responsibility: if he chooses something that is 'industry best practice,' and the company loses, he can't be blamed. He didn't choose, the industry did."

It is generaly assumed that innovation fuels growth, but this implies risk. But which risks should you take and which should you minimise? If you have an established development shop, then the technicalities of a new product might be viewed as sufficient risks without adding a new language to the mix. On the other hand, shouldn't the company fund some sort of research project so that net time around the new language is not an unknown ? Otherwise you end up like the Knight from the cartoon going into battle, not having talked to the machine gun salesman.

And some more .....


Passion, entrepreneurship, and the rebirth of local economies: " It's trying to put responsibility where responsibility can be, in fact, applied--grassroots. Let me tell you what I've done in my life.

I was so disgusted by what I saw, that when Ernest Schumacher published Small is Beautiful: Economics as if people mattered in 1973, I went ballistic. I said, this guy is telling us the truth about what development is! And I wanted to follow him. I wanted to look at alternative development. What can we do that makes sense?

And so I left Italy, I left my agency. Initially I went to Africa, to Stellenbosch University in Cape Province, and then I went to Australia. And I researched anything that was a caring, intelligent way of helping people help themselves. And I came up with the most radical thing. I could not find anything as radical as what I've done."

Conflicting views on Sun's Open Source statement(s)


Groklaw doesn't like Schwartz statement, like ESR's rebuttal, and wonders if the bad mouthing of Red Hat[ammended]Open Source is part of Sun's settlement with Microsoft:GROKLAW

On the other hand Simon Phipps says that this is not based on any new interview with Schwartz, that ESR was fed a provocative line by eWeek and hence he came out fighting (as only he can):Webmink's take

So there is probably an element of the tech. press stoking things up during a slow news day. But there were enough ambiguous/worrying statements in the first eWeek interview to make Sun vulnerable to this sort of thing.

I think a reasonable response to ESR by Sun, plus any clarifications they wish to make with hindsight would be a good move here.

I think most people realise that we have a software community using a variety of business models - the bold (therefore newsworthy) but unhelpful arguments like all "Open Source is bad/communist/starving my children/blahblah" or "I'm more Open Source than you" doesn't help anyone.

AMMENDMENT: As Simon points out in the comments, the Sun's questions about Red Hat weren't criticisms of Open Source. I'd really love to know what they all really meant though!

Legalise torture?

Why America's top liberal lawyer wants to legalise torture

I see what he is saying, but I think it is wrong. Maybe I am too wedded to the idea of "do onto others, as you would have them do unto you" - and yes it applies across religions.

Is going in front of a judge first, somehow sanitising what follows ? What verifiable facts could be presented to such a judge? When a judge of a foreign country has a similar power over coalition captives ?

This is indeed a slippery moral slope, and we are accelerating.....

Where to start on this one ?


  • The USA and its allies need to show the world that there is an alternative to barbarism
  • You don't save lives (American or other) by turning a candidate "beacon of democracy in the Middle East" into another recruiting ground for terrorists
  • There is plenty of evidence that some prisoners should never have been brought in - they can't tell the interrogators anything, because they don't know anything
  • In every conflict it easy to vilify the opponents, make them less than human. The Geneva Convention was an attempt to halt this animal instinct.
  • Are you telling me that those photographs show part of an interrogation ? They were(Mainly) a bunch of people out of control.
  • Are ther any real interrogators there?

Events and Business Processes


Sean McGrarth makes the following point: E-BUSINESS IN THE ENTERPRISE - When modelling business processes, upside down is the right way up:

"In this model, the programmer drives the business process onward, dictating the tempo which applications must follow. There are numerous terms used to describe this approach but my favorite is 'temporally coupled'. Applications must work in lock-step with each other for business process to function as they should.

This is a point solution. Why? Because it only works well when all the applications underfoot are under your control and (preferably) on the same physical network. Under those conditions, temporal coupling is manageable. Costly but manageable. The more general case of course is where not all the applications are under your control and not all on your local network. Web Services on an Extranet or the Internet for example.

To handle the general case of Web Services owned and hosted by other organizations, with the varying quality of service that that entails, programmers need to take a different approach to pan-application business process modelling. Instead of driving business processes programmatically, they need to deal with the fact that they are no longer completely in control. Web Services respond at different rates, they may not be up all the time, they will produce garbled data because somebody changes something without telling you and so on."


This seems natural to me; the ability to centrally model a process, even within a single company, is often an exercise in wishful thinking. Better to describe interconnecting patterns of behaviour and synthesise a view of how the parts work together.

Unless I misinterpret, it seems to me that UML Activity diagrams with Events can be used to model and view the results; what is the best mix of technologies underneath ? And can we generate these (or parts of these) from the UML diagrams?

Peace Pilgrim


Steps Toward Inner Peace by Peace Pilgrim via Crossroads Dispatches

I have only had a chance to skim the "booklet" but this paragraph hit home in our present circumstances:

MAGIC FORMULAS: There is a magic formula for resolving conflicts. It is this: Have as your objective the resolving of the conflict, not the gaining of advantage. There is a magic formula for avoiding conflicts. It is this: Be concerned that you do not offend, not that you are not offended.

Must return for another look.......

Well worth the read.

Was the Blackdown Java for Linux open source?
And why are users trapped by having to use THE professional?
And if you provide reasonable quality free(beer) software on all platforms, software which has a compliance suite why would there be an open source version? If Sun radical ly changes the Java license (and it is legal) an open source version will happen (unless a better language platform comes along )

Dave Winer, Userland: Open Source?????


Scripting News: 5/17/2004

Congratulations to Dave and Userland on a bold decision. My interpretation of Dave's blog has been that it is very much against Open Source, along the lines of "how do I survive/eat/prosper/do new things?"

Still, here we see, courtesy of a blog , some of the rationale for their decision. And it makes sense to me ( so it must be a good idea). "This is no longer core to us, but could be useful to others, so let it free!!"

(Reminds me of "Master and Commander" when they have to leave the carefully gathered samples behind to get back to their ship quickly - "Open the cages!")

So, when else does it make sense to open source things?

Movable Type: it's the whole feature set


Dan Bricklin emphasisies a really good point here:

The thing to learn here is that the choice of how you differentiate between users for pricing is a key element in a product's feature-set. You had better be pretty clear about the philosophy behind that differentiation and change it at your peril. Reactions to the new Movable Type licensing scheme

Movable Type Controversy


Never used it myself, but many peole do. My main interest is that somehow people look at this situation and draw conclusions about Open Source software. Which is odd because I don't think MT is open source!

Here is what I regard as a well resoned look at the siruation for MT:
Brad Choate: Movable Type 3.0

His take seems to be that people who want to continue to use MT free ( including the new version) can do with pretty much the same restrictions as before. Maybe those who had to pay now have to pay more? Not sure: MT for use by more than one person and more than 3 blogs have to pay, any commercial activities ditto. Sure sounds like they should pay for something.

I have seen some talk about people who have contributed add-ons to MT being a bit sore about the situation. This is more understandable, but unfortunately, read the license !!

Anyway , folks , please don't infer any Open Source generalisations from this episode.

EU is getting more Stalinistic


Two problems:


  • The EU political system is does not work properly. It is currently operating around the level of England before its Civil War - perhaps one day the EU Parliment will be properly elected and actually have some power. The Council of Ministers is too powerful, and goodness knows why it can overrule parliament. And why does the Commission have the power to advance Policy ?
  • Software patents: by all means protect innovation, but the future (especially of increased employment) lies with growing smaller firms, not big ones defending their eroding competitiveness

Making America .....


Seen via GT:Making America Our Own Again - A speech I'd like to hear: David Weinberger

A couple of things strike me: "Gosh, couldn't see a Brit saying that". But perhaps some did in the 18th/19th centuries?

Similarly, was there a period in Republican Rome when its citizen's thought they could improve the world?

The route from "Let us help you", via "We know best", to "We're better than you" is short and easy

I applaud David for what he has written, and I hope that his vision of a better world comes to pass, though I think it would be better if a growing team of nations lead this improvement.
