UVC support soon in vanilla kernel?

multimedia
In a recent interview with the German IT online magazine Golem.de the kernel developer Greg Kroah-Hartman mentioned that the USB video device support will soon be merged into the vanilla kernel.

Many USB video devices (like Webcams, etc.) do work via the UVC standard. There is of course a Linux driver available, however this is not part of the vanilla kernel yet due to problems with the Video4Linux implementation. Therefore it has to be compiled manually or is added afterwards as a patch by the distributions. Fedora 9 and the new Ubuntu 8.04 for example do include the driver with their kernels.

Now in an interview with the German Golem.de Greg Kroah-Hartman mentioned that it is planned to merge that device driver in the near future into the mainline kernel:

There is a standard for USB video devices and the corresponding driver will soon be merged into the kernel.

If this really happens than video devices on Linux will make a big step forward: first of all a huge set of devices will be supported out of the box. Second, the support can be expected - therefore application developers can rely on it and can develop applications incorporating such video devices. Third, the developers behind the driver finally get credit for their great work and can continue the development on a stable base and with a clear future. And last but not least, the distributions have one patch less to worry.

Besides this information GKH identifies two big problematic fields in the current Linux device driver world: WLAN and video devices. WLAN just became much more sane and easy due to the new stack, but Broadcom devices are still a problem due to lacking support from Broadcam. And while video graphic cards support is getting better due to published specifications (NVIDIA, you are the only one missing!) many devices like video cameras and similar are still a problem and not well supported yet.

It is good to see that the kernel device developers have a clear picture of which device drivers are missing. And btw., it is nice to see that these drivers are for average desktop devices for normal users. So in this regard the kernel developers have an eye on the desktop.

Meizu M3: Linux compatible MP3/Ogg player

Tux
There are several audio players out there capable of playing Ogg Vorbis. One of these which works perfectly together with Linux is the Meizu M3.

Originally I had an iAudio U2 player - that device was close to perfect: long battery life time, 2 GB storage, small, beautiful, capable of playing MP3 and Ogg Vorbis, and so on. Unfortunately, that one was stolen quite some time ago (the first thing ever stolen from me :/ ).

Later my girlfriend wanted to have a MP3 player and settled for the Samsung YP-T9JQB (which has of course Ogg Vorbis support). With a new firmware this one also worked pretty well with Linux. The only shortcoming is that you have to invoke a rescan of the music database manually after unplugging the device and that it is detected as two drives by Linux.

Now it was time to get myself a new player - and I chose the Meizu M3 - called “Music Card” - in white with 8 GB. Besides the obvious Ogg Vorbis support it also has the ability to switch between USB Mass Storage and MTP. This makes it possible to use the player just as you like with all kinds of operating systems (especially with older Linux, Windows 2k or Windows XP without the newest Windows Media Player) since these do only support USB Mass Storage. Luckily it also rescans the music database automatically after unplugging. Also it is sold at reasonable prices. I would only have wished that the battery life was as unbelievable as with the U2, but for a price around 100 Euros you can’t expect everything.

So if you look for a shiny new audio player and don’t want to buy iAudio, Meizu is another good option.

Microsoft’s ecosystem: cracks in the reliability

microsoft
The microsoft ecosystem is often mentioned to be long term reliable and therefore be a good option for companies with long term plans or needs. However, recently some parts of Microsoft’s ecosystem fall apart and became incompatible, which is not what you expect from a reliable system.

The Microsoft ecosystem consists of thousands of services and applications provided by 3rd parties. However, the foundation of this system is provided by Microsoft’s services, applications and it’s Operating System. When these are suddenly not reliable anymore the ecosystem is suddenly not stable at all.
And there have been three large cracks in the near past which should make everyone worry who bases his or her IT on Microsoft’s products: PlayForSure, Outlook Express/Hotmail, and to some degree even OOXML.

PlayForSure

PlayForSure (DRM codename: Janus) was introduced by Microsoft in 2004/2005 to mark players which have been certified to follow Microsoft’s dream list: Windows Media Player compatibility, DRM support, MTP-only support, and so on. Originally this was also an attempt to push Ogg Vorbis out of the field.
The basic idea was that every player could be used on any Windows System which had Windows Media Player 10 installed. And that every player would play any music sold in any PlayForSure store.

The shortcoming for the user would be that the players and music wouldn’t work outside of this system (Apple, Linux, Windows 2000, Windows XP without the WMP 10, etc., other MP3 players). And if the user wanted to switch to a new computer, he/she had to re-download a licence for the new computer. That’s a usual problem with DRM, but is important in this regard.

So the ecosystem was built up, and almost every new MP3 player on the market was certified against PlayForSure. Millions of songs were presumably sold to probably millions of users.

But then Microsoft decided that PlayForeSure is not as cool as the iPod, and published an iPod enemy, the Zune. But since the Zune had to be Microsoft-Only it wasn’t Play Fore sure. The ecosystem got it’s first crack. And then Microsoft thought that having two systems was a bit confusing and closed down PlayForSure at the end of 2006. In the future the label “Certified for Microsoft Windows Vista” is supposed to replace PlayForSure. But while that certificate has some elements of the former PlayForSure it - for example - requires Windows Vista and has other, additional requirements. It is a new logo.

What we have now is a broken ecosystem. And that although most of Microsoft’s partners relied on the availability of PlayForSure - many of them still advertise their products as PlayForSure certified.
So now we have hardware vendors who have to push out a new line of players which can be certified against the new logo. All their old devices now depreciate because they are not certifed against the new logo.
And we have the webshops which sold PlayForSure music. Many of their customers for sure still use Windows XP - which is of course not Vista ready. They are left alone a bit.
Last but not least we have the customers: music which was bought with PlayForSure needs licence upgrades to work on a new computer. Since these licence upgrades will not be provided after PlayForeSure’s shut down the music is essentially worthless. Think of millions of songs here - think of millions of dollars/euros here!

Outlook Express and Hotmail

Outlook Express is an e-mail client shipped with all Microsoft versions since Windows 98 and before Windows Vista. Although it was responsible for many large scaled virus attacks and spreads due to a horrible security concept and had many more, other technical shortcomings and problems it was widely used. And it was of course often used with Microsoft’s own E-Mail service, Hotmail.

However, recently Microsoft decided that the old protocol used for the communication between Outlook Express and Hotmail wasn’t what they would prefer. They wanted to switch every user to the new DeltaSync - and so they decided to drop Outlook Express support in Hotmail. As a resultyou will not be able to use Outlook Express together with Hotmail in the future any more. Instead, you have to upgrade to Windows Live - if you can, because currently it does not support Windows XP 64 or Win2k3. Also, if you used to use another client, that one will also not work anymore.

To summarizes: as a user who relied on Microsoft’s in house e-mail technology you are screwed.

OOXML

The last problem is still in development, and the outcome is not really clear at the moment. But the root of the problem is ISO’s adoption of OOXML.
Originally published by Microsoft to have a pseudo-standard which is very hard to support for other software vendors, the ISO adoption process became necessary because no one was interested in not officially standardized formats by Microsoft.

So OOXML went through the ISO process, and got several comments where it has to be reworked - Microsoft could have avoided this by working together with others right from the beginning! In the end the new format was accepted as a standard. But the necessary revision of the format resulted in a non-compatible Microsoft Office:

Such a test is only indicative, of course, but a few tentative conclusions can be drawn:

  • Word documents generated by today’s version of MS Office 2007 do not conform to ISO/IEC 29500
  • Making them conform to the STRICT schema is going to require some surgery to the (de)serialisation code of the application
  • Making them conform to the TRANSITIONAL will require less of the same sort of surgery (since they’re quite close to conformant as-is)

Given Microsoft’s proven ability to tinker with the Office XML file format between service packs, I am hoping that MS Office will shortly be brought into line with the 29500 specification, and will stay that way.

I’ve included the last part (emphasis not by me) to make the point of view of the poster clear. He thinks/hopes that MS will update the Office suite soon (an ODF test suite can be found here, btw.). However, Microsoft haven’t published any time frame, schedule or plan yet about such an update.

So in the end Microsoft first created an ecosystem around its new file Office Suite and on full purpose introduced a file format which would never become an ISO standard in that form - to afterwards apply for the said standard and change the file format again. As a result Microsoft Office 2007 still is not compatible to the new OOXML version itself atm.

Every organization and every software vendor who already jumped on the OOXML train before the ISO changes therefore has now to reconsider the software strategy: it should prepare for the switch to the updated OOXML - but also wait with it because it is unclear when the switch in MS Office will come.

However, preparing such a big update and keeping it ready consumes quite some resources. And small software vendors might not have these resources. Additionally, even smaller vendors which only had the resources to accept the new file format once are screwed.

And of course we have the users: everyone who tried to base a long-time backup solution on top of the old OOXML is screwed as well and should re-build the entire update again with the new OOXML.

Final words

The main problem behind these cracks in Microsoft’s ecosystem is of course the lack of well proved, open standards. But since Microsoft is not willing to support standards, the cracks are there now, and they are huge.

Of course from Microsoft’s point of view all these things make totally sense: everyone who strictly follows Microsoft as close as possible (use Vista only, etc.) and is ready to lose quite some money once in a while (because the music must be bought again and again or similar) will survive all these changes.

So to summarize the problem with respect to Microsoft’s position: problems only occur where users don’t have money to waste or want to have choice. Microsoft does not want the user to choose anything. The user is there to consume, not to choose - or actually think. This is best expressed by a comment from Omar Shahine, one of Microsoft’s Lead Program Managers, who tried to explain the Outlook Express/Hotmail development:

What we didn’t want to do is offer POP access and then have [...] customers use POP over DeltaSync.

If customers decide to stay with a product despite you offer them a new one - that means the customers prefer the product. Usually a company has to stick with such things in the real world.

However, Microsoft thinks it knows better. Microsoft forces it’s users against any opposition. And against any possible casualties on the consumers side.

The new one in town

VirtualBox for OpenSolaris hosts available - FreeBSD soon?
Sometimes old ones have to be replaced - with something fresh and new. I’ve got a new laptop.

The old one

I’ve had my old laptop now for over three years. Back then it was state of the art: A Cebop T900 (the company doesn’t exist anymore, but the series is comparable to Siemens Amilo series of that time) with fresh 1,8 GHz Centrino (Pentium M 745, Dothan core) with - at that time quite large - 1 GB RAM and a 80 GB Hard disk. The graphics card was an ATI 9600 mobile with 256 MB RAM which actually was more of a desktop graphics card then a laptop card. The wireless card was an Intel ipw2200, and there was even a card reader installed, though I never got that one working. The screen was a 1280×800 15.4″ wide screen. Some benchmarks can be found here

The old one - called Perricum, btw. - served me well. However, due to the ridiculous oversized graphics card (and probably due to the entire construction at all) the fan never stopped working. And the fan was really, really noisy. Additionally, the entire chassis was not very stable. Still, the laptop accompanied me during the last years (and to several countries, btw.). For the distribution interested person: I started back then with a pre-release version of Mandrake/Mandriva (because it was the only one which started on that machine at that time due to kernel problems), later on Fedora and also for some time OpenSuse followed. The virtual machines started inside of the system run almost everything, from Ubuntu over the already mentioned distributions to even some BSD versions I gave a try. Also, for some time a virtual machine contained a Windows copy.
Speaking about Windows: besides the virtual machine that computer never saw a a Windows Kernel. The machine came along without a preinstalled operating system, and I was already in a state where I didn’t need any Windows. The need came later up for some months due to some specialized Windows-only program, but that was all.

The new one

In 10 years my mobile phone will most likely have more power than my new laptop - but today it is state of the art: A Dell Latitude D630 with a Intel T9300 with 2.5 GHz Dual Core (6 MB Cache, btw) - yes, that’s the new Penryn, Intel’s new 45nm processor series. Again, the RAM is quite high even for today: 4 GB. The hard disk is comparable small, just 160 GB, but for me power consumption was more important than size. And I do have an external hard disk.
But I also from the problems with my old machine: the graphics card is not a desktop card this time, but a Nvidia NVS 135M, a business card from Nvidia’s Quadro series. I could have also taken the laptop with Intel’s X3100, but since this machine is supposed to serve me for a longer time I wanted to have at least a bit more power. The wireless card is a 4965, and the screen is a 14.1″ with a resolution of 1440×900. Some benchmarks can be found here.

Additionally, this is a business notebook: so there are less fancy things (no card reader for example, no TV out, etc.), higher costs, but also more reliability: a much, much better and more stable chassis, high quality hardware (the speakers for example), and so on. And it has docking station support, which I plan to use quite often in the near future.

The operating system choice was a lit more difficult in this case, however. Dell doesn’t sell its flagships with Linux - at least not to usual customers. Additionally, since I am an author for technical magazines sometimes I am asked if I could do a story on some Windows related topics - like “Connect Windows to Linux” or “Compare xyz on Windows against abc on Linux”. Since I didn’t have a Windows copy in the past I had to pass on these tasks. Also, having a look at Vista once in a while makes me able to compare it against Linux distributions.

So I payed money for a Windows Vista copy. The disadvantages are now that that Microsoft earned some money and that my hard disk is littered with a lot of crap - almost two GB are taken by the problem that I only got a “Recovery DVD”. Sigh…

Sooo…

As a result I will publish more posts about the new computer - for example the task of installing Linux on it was much more difficult than I have thought! Also I will install a more recent KDE on this machine - one way or the other. But for now I’m just happy to have a new computer which is strong enough to do all the things I would like it to do but is not too noisy to work with or to heavy to carry around. :)

fsdaily.com - a digg-like portal for Free and Open Source Software

VirtualBox for OpenSolaris hosts available - FreeBSD soon?
Recently I stumpled on the project fsdaily.com. It is a digg.com-clone but is focused on Free and Open Source Software. While the community seems to be rather small yet it might be an interesting news source in the future.

When I came across fsdaily.com I noticed an interesting piece of news about future EU plans to buy more Open Source software. It caught my eye because I hadn’t read that anywhere else at that time. Therefore I had a deeper look at fsdaily.com, and must say that it looks rather nice.

The more important question however is if it will suffer the same problems as digg.com. While I loved digg.com when I first discovered it I dropped it some months later due to quite some disappointments: digg is, after all, just a place for the masses. So the relevance is also defined by the masses. And well, the masses love sport, glittering things and naked skin. The equivalent in the software world might be iPods, themes and desktop screenshots. That’s ok for the masses, but as a result digg.com is just not the place if you want to get decent information or want to follow technological development.

That however might be the case with fsdaily.com - although I must admit that even the FLOSS world might have it’s equivalent for sport, glittering and naked skin in the form of a dozen hot flame wars. But at the moment the situation looks rather calm, and due to the specialized focus I think the topics will stay more technique related and really interesting than just glittering.

Also since it is still a quite small project, you can still influence it quite a lot with just a couple of people. So where is the next Commit Digest? In the end it’s the community which decides which news are interesting.
