JaDa's blog about Opera and Linux

I usually work on Free things. "Free" doesn't just mean zero cost; it means the freedom to copy, to share, to modify and redistribute without arbitrary restrictions.

The reason why the latest Flash doesn't work

, , , ...

The reason why the latest Flash doesn't work originally appeared to be its new support of some Mozilla XEmbed-based extensions to the plugins API (funny thing about that link is, it says that it finally makes it work with Opera, while in fact it's exactly the opposite). After adding XEmbed support to Konqueror, it still didn't work. The page about the XEmbed extension has demo code hardcoding a hard dependency on Gtk2, so maybe adding Glib2 eventloop support will make it work? After all, the Flash system requirements page mentions this (well hidden in a footnote, if you look close enough), but not really, tough luck, even though the DiamondX testing plugin already works. Do you know what a ballistic approach to debugging is? You either hit, or you don't. Here next hit is that this Flash version doesn't handle properly repeated NPSetWindow() calls, which however happens to be the case with Konqueror. So finally, does it work? Well, kind of, if you don't mind it crashing everytime you leave a page. And it crashes in XtRemoveTimeOut() (incidentaly, a function that should not be called by a Gtk2-based plugin). That's been already taken care of as well - it's enough to give Flash the user agent string from Firefox, suddenly, no crash (I have no idea how Maksim managed to find this out - probably involved sacrificing chicken or something).

So, when can you expect the latest Flash to work with KDE? I have no idea.

Yes, I know a Flash developer contancted kfm-devel somewhen in the past asking about XEmbed support. That still doesn't make debugging Flash any less painful, which is why the workarounds for it will take unknown time. It also doesn't change anything about Adobe not really giving a damn about Konqueror or Opera, if they could suddenly drop backwards compatibility (even though the code is probably still there, if it can still call XtRemoveTimeOut() and crash on it).

Use OpenOffice.org online with Ulteo !

Register to be one of the 15,000 beta users

Beta users will be able to access OpenOffice.org online with collaboration capabilities through the Ulteo Online Desktop

The latest version of OpenOffice.org is now available using a browser with a single click of a mouse, with no download or installation process ('no install') of the productivity suite required. This new service by Ulteo offers many benefits for users of the productivity suite, and has been well received by early beta users across Windows, Linux and Mac operating systems.

Collaboration:
As well as offering instant 'no-install' access, Ulteo's service also provides OpenOffice.org users with instant collaboration capabilities. A user working with OpenOffice.org on the Ulteo server can invite other people to work with him or her on a shared document in real time. Invitations are sent via email and allow access in either read only or full edit mode, simply by clicking on a link in the email.

Collaboration was a hot topic at the recent OpenOffice.org Conference. “Now everyone can use OpenOffice.org, from any connected PC, anytime, anywhere” said Florian Effenberger, Marketing Project Co-Lead of OpenOffice.org. “You even can work together on documents online and collaborate with others. This especially is an interesting option for trainers and workgroups.”

Collaboration features of Ulteo permit real-time on-line training, another hot topic for the rapidly growing number of people migrating to OpenOffice.org. Hundreds of OpenOffice.org professional trainers around the world or experienced users in the community are now able to offer the service, opening up exciting possibilities.

Instant trial:
Making OpenOffice.org available through a browser should also help accelerate its adoption by an even broader user base. Users can introduce OpenOffice.org to others via email, invite them to discover OpenOffice.org with just one click, and can give a personal tour of the program. Very soon, bloggers and journalists will be able to add a link to OpenOffice.org in their articles for readers to click through and try the program.

John McCreesh, Marketing Project Lead at OpenOffice.org, welcomed this announcement by Ulteo: “This is an interesting development for people who want to try out OpenOffice.org without having to download and install the software. If you're wondering how OpenOffice.org compares to your current office software, this is a convenient way to see OpenOffice.org in action in a browser on your desktop. Take OpenOffice.org for a test drive today!”

Using Ulteo's service, users can exploit features of OpenOffice.org which may be missing from their current desktop software. For example, OpenOffice.org can read and write Microsoft Office files and generate .pdf format files without requiring any additional software. OpenOffice.org also reads and writes documents in OpenDocument Format, the ISO-approved standard for office documents, which can only be read in Microsoft Office after installing a plug-in.

This new service is provided by Ulteo:
Ulteo powers the online version of OpenOffice.org (see http://www.ulteo.com). Ulteo is a new project initiated by Gaël Duval, recognized for developing a user-friendly Linux distribution now enjoyed by millions of people around the world.

Ulteo aims at simplifying the way people use computers so they can enjoy applications and data rather than spending time on tedious tasks. "Ulteo is very proud to deliver OpenOffice.org to the community in a new, useful and exciting way: online and designed for collaboration. We expect that it will contribute to spread OpenOffice.org to even more users now that it is simpler than ever to try and use it in a couple of clicks" says Thierry Koehrlen, CEO of Ulteo.

With Ulteo, OpenOffice.org becomes the de facto best online productivity suite. It is standards based, mature, with lots of of features.
Ulteo is inviting 15,000 new OpenOffice.org users from Europe and North America (where the Ulteo servers are located), to test the suite online. Just register on http://www.ulteo.com/home/ooo

about Linux

, , , ...

Linux

Linux (also known as GNU/Linux) is a computer operating system. It is one of the most prominent examples of Open Source development and Free Software; unlike proprietary operating systems such as Windows or Mac OS, all of its underlying source code is available to the public for anyone to freely use, modify, and redistribute.

Initially, Linux was primarily developed and used by individual enthusiasts. Since then, Linux has gained the support of major corporations such as IBM, Sun Microsystems, Hewlett-Packard, and Novell for use in servers and is gaining popularity in the desktop market[1]. It is used in systems ranging from personal computers to supercomputers and embedded systems such as mobile phones and personal video recorders. Proponents and analysts attribute its success to its vendor independence (the opposite of vendor lock-in), low cost, security, and reliability

History

In 1983, Richard Stallman founded the GNU Project, with the goal of developing a complete Unix-like operating system composed entirely of free software. By the beginning of the 1990s, GNU had produced or collected most of the necessary components of this system—libraries, compilers, text editors, a Unix-like shell—except for the core component, the kernel. The GNU project began developing a kernel, the Hurd, in 1990, based on the Mach microkernel, but the development of this Mach-based design proved difficult and proceeded slowly.

Meanwhile, in 1991, another kernel was begun as a hobby by Finnish university student Linus Torvalds while attending the University of Helsinki. Torvalds originally used Minix on his own computer, a simplified Unix-like system written by Andrew Tanenbaum for teaching operating system design. However, Tanenbaum did not permit others to extend his operating system, leading Torvalds to create a replacement for Minix.

Originally, Torvalds called his kernel "Freax" for "free" and "freak" and with the often-used X in the names of Unix-like systems. The name "Linux" was coined by Ari Lemmke, who administered an FTP server belonging to the Finnish University Network; he invented the name Linux for the directory from which Torvalds' project was first available for download.

At first a computer running Minix was necessary in order to configure and install Linux. Initial versions of Linux also required another operating system to be present in order to boot from a hard disk, but soon there were independent boot loaders such as LILO. The Linux system quickly surpassed Minix in functionality; Torvalds and other early Linux kernel developers adapted their work for the GNU components and user-space programs to create a complete, fully functional, and free operating system.

Today, Torvalds continues to direct the development of the kernel, while other subsystems such as the GNU components continue to be developed separately (Linux kernel development is not part of the GNU Project). Other groups and companies combine and distribute these components with additional application software in the form of Linux distributions.
