KDE 4 to Support Apple Dashboard Widgets

Ryan writes to tell us Applexnet is reporting that Zack Rusin, a lead developer of KDE, has confirmed that KDE 4 will be able to run and display Dashboard widgets similar to Mac OS X 10.4. From the article: "Basically, this means that a layer (similar in some ways to layers in Adobe Photoshop) in the KDE desktop could function the same way that Dashboard does in Mac OS X. Widgets themselves are not inherently difficult to write nor properly interpret, since they are usually just HTML and Javascript (although Cocoa code can be included, the developer's skills permitting). Furthermore, since Konqueror and Safari share very nearly the same rendering engine, KHTML and WebKit, this too will simplify the process."

      Perhaps it will lend something to KDE.

      They already do. Safari is descendant of Konqueror and contribute (perhaps inefficiently) their patches back to KDE. However, since this is KDE's own effort to reproduce Dashboard from scratch (Dashboard isn't open source even if many of its components are), Apple has no reason or incentive to contribute any of their work on Dashboard to KDE.

      Most UNIX-people use Apple because it still is UNIX but with a better GUI.

      This needs to be qualified a little better because the a large number (most likely the majority) of "UNIX-people" are still happily using a non-Apple Unix. For example, I use KDE and don't see that changing anytime soon because KDE is, for me, a much more powerful UI environment than OS X. Most of my geek friends and co-workers are in the same boat, though some are considering Powerbooks for the occasional on-the-road work.

      Perhaps KDE will convince Apple to make the GUI Free Software.

      Not going to happen and literally everyone at Apple has said as much. The simple, elegant OS X GUI is Apple's trump card. It is the main reason to buy a Mac. If they give that away, then anyone on the planet can implement it and Mac sales go down the tube. Sure, there are many reasons to buy a Mac but the OS is definitely the biggie. This is why Apple is putting so much effort into making sure that OS X does not run (easily) on plain Intel boxes.

      Or maybe Apple will just sue the socks off of the KDE project.

      I don't see how that's possible unless Apple went patent-squatting on the desktop widget engine idea. Dashboard may be the most popular implementation, but it was hardly the first to exist.

    I still consider 395 megs of memory used when using the K web browser and file system to be too much.


    I currently have following things running on my KDE-desktop:

    - Konqueror with 4 tabs
    - Kontact
    - Konsole
    - Basket
    - Kopete
    - Bunch of KDE-related services (Wallet-manager, Klipper etc.)
    - The usual Linux-services

    How much RAM is being consumed? 149 megs. Let me repeat that: KDE, with all those apps running plus host of other Linux-services, is consuming 149 megs of RAM. Not exactly the 395 megs you quoted, now is it? Let's make this interesting, shall we? I also often run K3b, Amarok (with 7gig music-library), Codeine and Kword. How much RAM is being consumed with those apps running as well (for a total of Konqueror, Kopete, Amarok, Kword, Codeine, Kontact, Basket and Konsole running at the same time)? 310 megs, it seems. So we are getting closer to your figure of 395 megs (which you claim KDE consumes with nothing but Konqueror running).

    If I add System Settings (this is a Kubuntu-machine), KPDF and Kate to the mix, RAM-consumption jumps to 323 megs. Still not the same as your figure. Adding SuperKaramba, Info Center and Help in there, and the system consumes 338 megs of RAM. Kspread and Kedit make the RAM-consumption to jump to a whopping 347 megs, still not as high as your figure. And I don't even know what other apps I could be running here. My taskbar is full of running apps, and the RAM-consumption is more than reasonable.

    I still am fond of when A GUI took up 20 megs, ran well with 12 megs of memory, and was almost instainious in response to commands. (Mac OS 7.1 and Windows 3.1 on a 68030 and 486 respectively)


    Then keep on using those old GUI's. If modern GUI's are slow and bloated, why are you using them?

    395 megs of memory is too much. K web browser never uses that much. In fact, konqi's memory usage if far below firefox's. The least amount of ram you need for kde is 192. With 256, it should work smoothly (you can even have some konq. instances preloaded). Using purely KApps makes the experience smoother than with WinXP. Now if you start firefox (which is a memory hog) or openoffice, and $insert_app_here, and you find yourself running out of ram, don't blame kde!

    This needs no special tuning whatsoever. Plain vanilla KDE will work fine without any tweaking on a puter with 256Megs. My main machine has 512, and even after extensive use, my swap partition isn't even touched. That with lots of apps loaded by default: skype, amarok, kmail, 4 preloaded instances of konqi, etc. My system begins swapping only if I start up firefox or ooo-build. (Or perhaps krita with an 50meg PNG :)

    KDE's memory management is very efficient. In fact, considering what it does, I would say that I'd expect higher memory usage. Of course, we can throw numbers around here with little or no way to back up our claims, I realize that, but if you check the specs of people running kde (on forums) you'll see that configs like a 700Mhz duron with 256Mb RAM (I mentioned this in another post) is enough. I don't know where your K browser using 384Mb RAM comes from (well, except if you pull it out of your ass). Actually I made some screenies of kde 3.4.3 here. One of the screenshots displays memory usage. If you check the clock, you'll see that it shows the state of memory after opening a lot of apps, including scribus, with images loaded, etc (and you'll see what I have running in my systray). So I don't understand people who report excessive memory usage of KDE - it is either FUD, or they should switch distroes :)

    That's exactly the problem with Dashboard though ... it's too tempting to approach it as "let's load it up with all types of crazy widgets!". By doing that, you make it less functional. (Takes longer to switch to them when you've got a whole screen full of them, etc.)
