仪表板vsKonfabulator

一个滑动拼图一个计算器一个时钟一个小记事本Tiny little applets — little pieces of software that are something less than full applications themselves, but which run alongside real apps and are easily accessed at any time.

显然,苹果公司扯掉了这个想法仪表板Stolen wholesale, without even the decency to mention where they took the original idea.

Which, of course, would be the desk accessories from the original 1984 Macintosh — conceived by Bud Tribble and engineered (mostly) by Andy Hertzfeld这是Hertzfeld对书桌配件的起源

Bud Tribble was usually on an even keel, but one afternoon in the fall of 1981 he came into my office, unusually excited“你知道,我一直在考虑它Even if we can only run one major application at a time, there’s no reason that we can’t also have some little miniature applications running in their own windows at the same time.”

这听起来很吸引人“What kind of little programs? How are they different?”, I wondered.

Bud smiled“You’d want tiny apps that were good at a specific, limited function that complements the main applicationLike a little calculator, for example, that looked like a real calculatorOr maybe an alarm clock, or a notepad for jotting down textSince the entire screen is supposed to be a metaphorical desktop, the little programs are desk ornaments, adorning the desktop with useful features.”

The post-WWDC peanut gallery is atwitter with the idea that Tiger’s Dashboard is a blatant rip-off ofKonfabulator你不能读什么about Dashboard without hearing that it’s a Konfabulator rip-off.

废话。仪表板不是Konfabulator的剽窃。Yes, they are doing very much the same thingBut what it is that they’re doing was not an original idea to KonfabulatorThe scope of a “widget” is very much the modern-day equivalent of a desk accessory.

What is original to Konfabulator? That its widgets are based on a scripting language? That’s not originalThere are a slew of other scripting runtimes that allow you to create little-applets-in-windows例如在旧的Mac OS,一键式

根据Konfabulator网站

What sets Konfabulator apart from other scripting applications is that it takes full advantage of Apple’s Quartz renderingThis allows Widgets to blend fluidly into your desktop without the constraints of traditional window bordersToss in some sliding and fading, and these little guys are right at home in Mac OS X.

That sounds right — the most striking thing about Konfabulator is that its default widgets look cool反锯齿的类型Round cornersTransparencyIn short, they’re clearly the work of a talented artist, that being Arlo Rose, who, before co-creating Konfabulator, had in factworked as a human interface designer for Apple在90年代,然后继续共同创造万花筒黑客攻击旧的Mac OS。

The crux is that what makes Konfabulator stand out is that its widgets look “right at home in Mac OS X”But is it any wonder that Apple’s Dashboard gadgets look “right at home” on Mac OS X, too?

[命名说明:Konfabulator称其小程序为“小部件”Apple’s Dashboard developer documentation refers to its applets as “gadgets”然而,在全球开发者大会,老虎预览section of Apple.com, Apple refers to Dashboard’s applets as “widgets”Until this is clarified, I’ll use “widgets” to refer to Konfabulator’s dinguses; and “gadgets” for Dashboard’s.]

It’s more than a little reminiscent of the supposed “controversy” over Panther’s greatly-improvedCommand-Tab切换器, wherein the fact that it (the Panther switcher) visually resembled Proteron’s Liteswitch X switching utility caused a bunch of knickers to get knottedMost infamously, Proteron developer Sam Caughron posted an “打开备忘录” wherein he took the position of victim — that he was an innovator done wrong by Apple.

But the functionality of Liteswitch X — using keyboard shortcuts to cycle through running apps — is over 20 years old, and present in every major desktop OS for the last decadeThe argument that Apple had “ripped off” Proteron more or less hinged in the idea that the visual resemblance between the new built-in Panther switcher and Liteswitch X couldn’t be a coincidenceOf course it wasn’t coincidence — but that doesn’t mean it was a “rip-off”.I wrote in October

Part of Caughron’s argument is that Panther’s implementation is “a near pixel duplication of […] LiteSwitch X” — meaning that they look the sameProteron did a fine job designing how LiteSwitch X looks, but it is not a novel design — it looks good because it looks like something designed by AppleIs it any surprise that Apple’s new switcher does too?

Also similar to the command-tab/Liteswitch X hubbub is that the consternation isn’t coming from the developer community, but rather from the peanut gallery of non-developersMac developers are not up-in-arms about Dashboard; in fact, the 9 a.mDashboard session Tuesday morning at WWDC filled up so quickly that they had to turn people away, long before the session started(Part of this is excitement over Dashboard itself; part is that there’s a contest for the best gadgets developed this week at WWDC, with the prizes being a 15" PowerBook and a 40 GB iPod.)

看看胡德

The idea, repeated ad nauseam in the initial reaction to Dashboard, is that Apple should have done the “right thing”, where “right thing” means “bought the rights to Konfabulator instead of implementing Dashboard on their own”.

But this implies that Dashboard is an under-the-hood equivalent to Konfabulator他们都使用JavaScript,对吗?

再想想Dashboard, from a how-it-works perspective, is very much different than Konfabulator.

Konfabulator contains its own self-contained JavaScript runtime engine,基于SpiderMonkey, the open source JavaScript engine from the Mozilla ProjectKonfabulator UI layouts are specified in a custom XML format即:

Konfabulator =(自定义XML格式)+(自定义JavaScript引擎)

Dashboard, on the other hand, is based on WebCore, the underlying open source layout and scripting engine behind SafariDashboard gadgets are indeed scripted using JavaScript, the same language used by Konfabulator, but Dashboard uses the JavaScript engine that’s built into the systemAnd for UI layout, Dashboard gadgets are specified using HTML and CSS — using the same rendering engine as Safari.

戴夫凯悦写道

I wanted to blog briefly to clear up what the widgets actually are written inThey are Web pages, plain and simple (with extra features thrown in for added measure). Apple’s own web site says “build your own widgets using the JavaScript language”, but that’s sort of misleadingThe widgets are HTML+CSS+JS他们没有一些JS-only的事情。

In other words, each widget is just a web page, and so you have the full power of WebKit behind each one… CSS2, DOM2, JS, HTML, XMLHttpRequest, Flash, QuickTime, Java, etcI’ll have a lot more to say later on, but I thought it important to clear that up right up front, since a lot of people were asking me about it in email and such.

Do you see how huge this is? How it opens the door to gadget development to anyone with web design experience? Indeed, I’ve read the preliminary Dashboard developer documentation (generously provided by a source attending WWDC), and it is outstanding from the perspective of making gadgets easy-to-create.

The idea that Dashboard is derivative because it’s scripted via JavaScript is missing the pointDashboard isn’t using JavaScript just to use JavaScript — it’s using JavaScript because Dashboard gadgets are little floating Web Kit views.

此外,使用Cocoa可以进一步扩展仪表板小工具You don’t需要to use Cocoa — fully functional gadgets can be made using nothing more than HTML, CSS, and JavaScript — but the option to use Cocoa is there for doing things JavaScript alone can’t do.

Thus, Dashboard is clearly an extension of Mac OS X system-level technologies: Web Kit for layout and scripting; Exposé for the Dashboard window layer; and Cocoa for advanced functionality. Dashboard is the result of advanced Mac OS X technology in action.

Konfabulator, on the other hand, was designed from the start with platform portability in mind(Windows的一个端口was announced back in December.)

That’s not to say Konfabulator widgets can’t use Mac-specific features; e.g能够调用AppleScriptsBut in terms of the underlying runtime engine, none of it is based on Mac OS X-specific technologies.

是的,不争论,仪表板是Konfabulator-killerTheir gadgets and widgets are serving the same exact purposeI.e., the answer to the question他们在做什么?是一样的But the answer to the question他们是怎么做到的?is completely different.

To assume that Apple started with the idea of putting Konfabulator out of business for spite is to ignore the more obvious reason why Apple didn’t buy out Konfabulator: they had something completely different in mind engineering-wise.

Do you see how it’s entirely plausible that Apple’s decision to base Dashboard on Web Kit and Cocoa was based on purely technical reasons? Konfabulator isn’t a产品- 它是平台. Konfabulator itself does nothing other than provide an environment and API for widgets.

Adding a new platform layer to the system is a serious decision and commitmentIf you’re still willing to argue that Apple should have bought Konfabulator as the basis for Dashboard, you’re implicitly arguing that Apple should be more concerned about being nice to third-party developers than they are about the quality of the engineering undergirding their platform.

Konfabulator is not a lightweight or small-footprint environment — every Konfabulator widget runs as a separate process, with its own runtime environment in memoryMost Konfabulator widgets use more memory than typical full-blown Mac OS X applicationsNot just Konfabulator as a whole — but每个小部件Install it, fire up Process Viewer, and see for yourself(Ironically, the Konfabulator “CPU Portal” widget seems to leak memory.)

For all of the armchair critics who claim to know that Apple “should have” bought Konfabulator to serve as the basis for Dashboard, I ask:

  • 你有没有用过的Konfabulator? If so, have you measured its memory consumption?
  • Do you think Apple’s OS engineers should be concerned about performance and resource consumption?
  • Do you think you know more about performance and resource allocation than Apple’s engineers?
  • Do you believe reasonable engineering opinions can be drawn by looking at screenshots?
  • 你是否意识到有一个知道的人是多么的侮辱没有about the details of your work tell you that they know better than you do?

Web开发人员作为小工具开发人员

It’s not hard to speculate on the reasons why Dashboard is based on WebCore technologyFirst, it’s already there — the JavaScript engine and HTML/CSS renderer are built-in components in Mac OS X. Second, basing Dashboard development on industry standard web technologies means that anyone who knows how to design a web page knows how to design a Dashboard gadget.

In terms of attracting hobbyist-level developers, Dashboard is going to be an order of magnitude more approachable than Cocoa application developmentIf you know HTML and CSS, you can design a gadget layout如果您了解JavaScript,则可以对小工具进行编程。

I can’t think of any possible way that gadget development could be based on something that would enable more Mac nerds to get up and running writing their own gadgetsThat the presentation is based on the相同HTML/CSS rendering engine as used by Safari makes it possible to test your layouts by loading them in the browser(In fact, that’s exactly what the Dashboard developer tutorial recommends.)

This, in fact, is the single biggest difference between Dashboard gadgets and the aforementioned desk accessories in the original Mac OSBecause of the tight memory constraints of the original Mac (only 128KBRAM,400KBof disk space per floppy), desk accessories needed to be as small and lightweight as possible. Which meant that they were mostly written in 68000 assembler code.

(他)的设计师Andy Hertzfeld。用Pascal编写the first version of the Puzzle desk accessoryin 1982, two years before the Mac shipped但在6点KB,它被认为太大了:

Jerome Coonen, the software manager, came by my cubicle one morning to tell me that they decided not to ship the puzzle, partially because of the game-like perception, but mostly because it was just too bigApplications were very tight on RAM, and the puzzle was one of the biggest desk accessories because it was written in PascalAt over 6K bytes, it also ate into the available disk space.

I liked the puzzle and I didn’t want to capitulate to the buttoned-down, all business view of the customer, so I told Jerome, “You know, the puzzle doesn’t have to be so bigI bet I could rewrite it and get it to take up less than 1K bytesWould you keep it if I got it that small, or is it really the other issue?”

Jerome thought about it, and then told me if I could get it down to 600 bytes or so, it would be in the releaseThe only problem was I had to get it done over the weekend, because they had to send the manuals out to the printer soon, and there was plenty of other stuff for me to work on.

当然,我忍不住一个挑战It only took a few hours on Saturday to recode it in assembly language, and get it down to the required 600 bytes, since it no longer had to link with the bulky Pascal codeI proudly showed it off to everyone on Monday, and it did make it into the first release, and stayed there for many years, although it was completely rewritten a couple of times, for various reasons.

Thus, the difference between the old world of desk accessories and the upcoming world of Dashboard gadgets: there are only a handful of people in the world who could write a puzzle game in the form of a Macintosh device driver using just 600 bytes of 68000 assembler; there are hundreds of thousands who can write one using HTML/CSS/JavaScript.

Desk accessories were harder to write than real Mac apps; Dashboard gadgets are far更轻松, and are based on web standards that people already knowDashboard gadgeteering is going to be hugely popular — largely because it’s based on web development technologies people already know.

泪流成河

在接受CNet记者Ina Fried的采访时(“Developer Calls Apple’s Tiger a Copycat“),Arlo Rose说:

“It’s insulting, is what it is,” Rose said in a telephone interview“They could have at least offered to work with us or to buy it.”

It’s natural for Rose and co-creator Perry Clarke to be upset; Dashboard is clearly a Konfabulator-killer(Rose to Fried: “We’re either going to have to move to another platform or work on some other project.”)

But what’s the argument that Apple has done something wrong? That if a third-party developer does something first, Apple should never step on that developer’s toes? Ever? No matter if Apple is already working on something similar but better? No matter if Apple can provide a显著better implementation? No matter if it’s something that would be a natural fit as an official component of the OS?

Scott Knaster— long-time Mac programming author — echoes Arlo Rose’s opinion of “the least” Apple should have done:

仪表板是有趣的It looks like a complete ripoff of Konfabulator, right down to the word “widgets”Shame, Apple至少买那个家伙的技术。

My question: Even if Apple considered Konfabulator’s technology undesirable?

In the lean years between John Sculley’s exit and Jobs’s return, Apple indeed seemed to follow this dictum of not stepping on Mac developers’ toesAnd you know what we got? Years of stagnation with System 7.5.

I am not advocating that Apple mindlessly trample on independent Mac developers — what I’m saying is that Apple cannot be afraid to improve the Mac OS as best it can, even if that means going places where small indie developers have gone first.

In cases where indie developers have created products that meet Apple’s own high standards, the company has shown that it’s willing to embrace existing solutions.

Most famously in recent years, iTunes — which started as SoundJam. Apple bought the rights, hired the development team (lead developer Jeffrey Robbin is now a serious big shot at Apple, helping lead all of Apple’s various music-related initiatives).

臭名昭著的,沃森/夏洛克的争议除非注意到Apple offered Watson developer Dan Wood an engineering position on the Sherlock team,伍德拒绝了This is of course contrary to the popular misconception that Apple “blindsided” Wood with Sherlock 3 (which had been in development before Watson debuted)Wood wanted compensation for the existing work he’d done on Watson, not just a job that would pay him for future work on SherlockTwice offering Wood a job on the Sherlock team doesn’t qualify as oppression.

That Konfabulator made it easy to create custom-designed widgets — does that mean Apple was obligated never to ship something that made it easier? With a smaller memory footprint? Isn’t it plausible that this was part of the plan for WebCore and Exposé all along — and that obtaining the rights to Konfabulator wouldn’t have helped them with this plan at all? Please keep in mind that just because they do the same thing from a user’s perspective doesn’t mean they do the same thing at all in terms of under-the-hood implementation.

Apple可能会雇用你为他们工作They may buy your code if they want it但他们不会因为一个人而付钱给你理念, nor should they be expected to.

There aren’t that many brand-spanking new ideas under the sun, and Konfabulator isn’t one.

The idea of “little apps” began with Apple’s desk accessories, 23 years ago.

The idea of a scriptable runtime for displaying little windoid applets is not original to Konfabulator(参看DesktopX的, a similar product for Windows that shipped in 1999.)

Even Konfabulator’s obsessive focus on the pixel-perfect cosmetic appeal of its widgets is not novelThe original Mac desk accessories were designed pixel-by-pixelThe standards for GUI showboating have certainly changed since 1984, but that’s only as a function of hardware capabilities.

Susan Kare’s amazing layout for the original Control Panel desk accessory involved no text labels, only graphics (screenshot from Folklore.org):

原始控制面板桌面附件的屏幕截图。

根据赫兹菲尔德(还有谁?),Steve Jobs personally designed every pixel-level detail of the original Calculator

在我关于Liteswitch X“争议”的文章的最后,我写

… when a utility is designed to compensate for a hole in Mac OS X, the developer should not expect the hole to remain unfilled by Apple forever.

If you’re going to compete, you’ve got to accept that you might loseKonfabulator is a software platform; Rose and Perry decided upon a rather closed platform model: the only way even to run a Konfabulator widget is to purchase a license to the runtime.

我对Konfabulator 1.0的评论我写:

What’s most perplexing to me is what Konfabulator does not include: an IDEThere is no visual widget editor or source code editorThey do include fairly comprehensive documentation on the widget XML structures and the supported JavaScript syntax, but when it comes to creating your own widgets, you’re on your ownArlo Rose, writing in the Konfabulator support forum, wrote:

Photoshop和BBEdit是你的朋友:-)

我们正在开发一个可视化编辑器,但我们是网络[SIC] yet sure when it will be released.

所以他们显然意识到需要一个IDEBut I can’t help but think it would have been better had they waited for the IDE before they started selling KonfabulatorAs it stands now, you need Konfabulator just to run a widget. Let’s say I have an idea for a widget-type application that does something very coolI wouldn’t write it for Konfabulator, because I wouldn’t want to limit the audience to those who’ve paid $25 for Konfabulator.

It makes more sense to me to give away the runtime engine, and let everyone run widgets for freeThen charge money for the IDE (and charge a bit more than $25)This makes widget-writing more appealing — you can share your work with the whole wide Mac world, not just the pixel-tweaking Konfabulator Klub.

A widget construction IDE would have made Konfabulator a product, not just a platform for pixel-pimping GUI tweakersIf they’d gone that route, they’d still have a future in the post-Dashboard world — by expanding the IDE to produce Dashboard gadgets in addition to Konfabulator widgets(Note to Mac developers looking for software ideas — hint, hint).

It was their choice to compete only on the basis of providing a widget platform.
