There are quite a few online diagram editors, but yUML.com is not a painting tool: It generates UML class and use case diagrams on the fly from image URLs. The samples page lists a few examples, here's a more complex one:

Fravia died on May 3rd, 2009. Long live his memories. Goodbye.

I've recently finished Markoff's great book on how the 60s counterculture shaped the personal computer history. Today, I've come across an interesting interview by him with David Gelernter.

David Gelernter .....

"...prophesied the rise of the World Wide Web. He understood the idea half a decade before it happened." (John Markoff)

"...is a treasure in the world of computer science...the most articulate and thoughtful of the great living practitioners" (Jaron Lanier)

"...is one of the pioneers in getting many computers to work together and cooperate on solving a single problem, which is the future of computing." (Danny Hillis)

"...is one of the most brilliant and visionary computer scientists of our time." (Bill Joy)

Watch (or read) the interview at Edge: The Third Culture.

Follow-up: Read about his 'worst enemy', technology hater and terrorist Theodore Kaczynski ("The Unabomber") and his manifesto Industrial Society and its Future.

96. As for our constitutional rights, consider for example that of freedom of the press. We certainly don't mean to knock that right: it is very important tool for limiting concentration of political power and for keeping those who do have political power in line by publicly exposing any misbehavior on their part. But freedom of the press is of very little use to the average citizen as an individual. The mass media are mostly under the control of large organizations that are integrated into the system. Anyone who has a little money can have something printed, or can distribute it on the Internet or in some such way, but what he has to say will be swamped by the vast volume of material put out by the media, hence it will have no practical effect. (...) Even if these writings had had many readers, most of these readers would soon have forgotten what they had read as their minds were flooded by the mass of material to which the media expose them.

172. First let us postulate that the computer scientists succeed in developing intelligent machines that can do all things better than human beings can do them. In that case presumably all work will be done by vast, highly organized systems of machines and no human effort will be necessary. Either of two cases might occur. The machines might be permitted to make all of their own decisions without human oversight, or else human control over the machines might be retained.

173. If the machines are permitted to make all their own decisions, we can't make any conjectures as to the results, because it is impossible to guess how such machines might behave. We only point out that the fate of the human race would be at the mercy of the machines. It might be argued that the human race would never be foolish enough to hand over all the power to the machines. But we are suggesting neither that the human race would voluntarily turn power over to the machines nor that the machines would willfully seize power. What we do suggest is that the human race might easily permit itself to drift into a position of such dependence on the machines that it would have no practical choice but to accept all of the machines' decisions. As society and the problems that face it become more and more complex and machines become more and more intelligent, people will let machines make more of their decisions for them, simply because machine-made decisions will bring better result than man-made ones. Eventually a stage may be reached at which the decisions necessary to keep the system running will be so complex that human beings will be incapable of making them intelligently. At that stage the machines will be in effective control. People won't be able to just turn the machines off, because they will be so dependent on them that turning them off would amount to suicide.

174. On the other hand it is possible that human control over the machines may be retained. In that case the average man may have control over certain private machines of his own, such as his car or his personal computer, but control over large systems of machines will be in the hands of a tiny elite—just as it is today, but with two differences. Due to improved techniques the elite will have greater control over the masses; and because human work will no longer be necessary the masses will be superfluous, a useless burden on the system. If the elite is ruthless they may simply decide to exterminate the mass of humanity. If they are humane they may use propaganda or other psychological or biological techniques to reduce the birth rate until the mass of humanity becomes extinct, leaving the world to the elite. Or, if the elite consist of soft-hearted liberals, they may decide to play the role of good shepherds to the rest of the human race. They will see to it that everyone's physical needs are satisfied, that all children are raised under psychologically hygienic conditions, that everyone has a wholesome hobby to keep him busy, and that anyone who may become dissatisfied undergoes "treatment" to cure his "problem." Of course, life will be so purposeless that people will have to be biologically or psychologically engineered either to remove their need for the power process or to make them "sublimate" their drive for power into some harmless hobby. These engineered human beings may be happy in such a society, but they most certainly will not be free. They will have been reduced to the status of domestic animals.

175. But suppose now that the computer scientists do not succeed in developing artificial intelligence, so that human work remains necessary. Even so, machines will take care of more and more of the simpler tasks so that there will be an increasing surplus of human workers at the lower levels of ability. (We see this happening already. There are many people who find it difficult or impossible to get work, because for intellectual or psychological reasons they cannot acquire the level of training necessary to make themselves useful in the present system.) On those who are employed, ever-increasing demands will be placed; They will need more and more training, more and more ability, and will have to be ever more reliable, conforming and docile, because they will be more and more like cells of a giant organism. Their tasks will be increasingly specialized so that their work will be, in a sense, out of touch with the real world, being concentrated on one tiny slice of reality. The system will have to use any means that it can, whether psychological or biological, to engineer people to be docile, to have the abilities that the system requires and to "sublimate" their drive for power into some specialized task. But the statement that the people of such a society will have to be docile may require qualification. The society may find competitiveness useful, provided that ways are found of directing competitiveness into channels that serve that needs of the system. We can imagine a future society in which there is endless competition for positions of prestige and power. But no more than a very few people will ever reach the top, where the only real power is (see end of paragraph 163). Very repellent is a society in which a person can satisfy his needs for power only by pushing large numbers of other people out of the way and depriving them of their opportunity for power.

Java: Elliote Rusty Harold, Easier testing with EasyMock.

"Any time you have an interface that needs to return certain results for purposes of testing, you can just create a quick mock. It really is that easy."

PHP: Matt Butcher, Get to know the QueryPath PHP library

"The new QueryPath library, a PHP cousin of the jQuery JavaScript library, offers an efficient API for working with XML, HTML, and HTTP. From Web pages to Web services, SVG to SPARQL, RDF to Atom, QueryPath provides a robust yet simple API for contemporary Web development in PHP."

Grails: Scott Davis, Mastering Grails: Authentication and Authorization

"In this article, I continue building a "tiny little blog" named Blogito. You'll learn how to enable logins, limit activity based on whether or not the User is logged in, and even add in some authorization based on the User's role."

Gyorgy Fekete put together a nice gallery of OS GUIs from 1981's Xerox Alto to 2009's KDE 4.

I am dreaming about a revived FidoNet. Ridiculous?

I guess I am not the only one who has to wait for signup confirmation mails. I am sitting here again, waiting (im)patiently for a simple email to finally show up in my inbox. Why in Gods name does every site require email confirmation before I can actually use it? Why not let me do whatever I was planning to do, like filling out my profile, posting threads, whatever, and let me confirm it afterwards to make it show up?

Please.

Turns out I was about a year late with my idea about a tipping/micropayment service, where you can give away small amounts (as small as 1 cent) to any URI you like as easy as clicking a button, without going to a tedious process and the requirement of the receiver to sign up first. I even thought about trying to get Y Combinator to seed fund me.



At least it shows that my ideas aren't that stupid after all. I have enough of them left.

At the moment, I am preparing for 'my most important exam', which happened to bring me to the website of Markus Völter, one of the current experts in Model Driven Software Development and Product Line Engineering. In his list of recent publications, I found a nice (German) article about the Jetbrains Meta Programming System. I've heard of MPS before, but his introduction is nicely written and understandble. Basically, MPS is a nice editor and composer for Domain Specific Languages. What makes it interesting is that apparently you can combine your own DSL with other languages, for example to easily extend a base language like Java with your own concepts. The DSL code is then transparently translated into the base language.
Also, you can use it the other way round, and extend your own DSL with concepts from existing languages, for example Java expressions. Continue reading "JetBrains Meta Programming System"

I'm still hunting for a good "all-inclusive" solution for backup, online storage and versioning. Lately, more and more services pop up (there's an incomplete list buried in my wiki), but TeamDrive stands out because you can use it with any WebDAV storage. I like Syncplicity for its ease of use ("zero configuration"), but I just don't feel well knowing that my files are out there, unencrypted, on some strangers' server.
Now that they've added HTTPS and Vista x64 support, I really need to try it. Also, it is the only tool in this area that doesn't require administrative privileges and runs from a USB stick ("portable"). Linux and Mac versions should be out soon.

Also, you might want to look at the somewhat similar PowerFolder (no versioning, no WebDAV support).
