    While the Sony's have lived in the modern world for awhile, and have gotten it, as well as being on both sides of it, Matsuhita electric is perhaps the most traditional and conservitive of Japanese companies. I have known these people (Matsushita) for much of my life, from some of their board members down. This is an organization so steeped in it's own traditions and dogma (yes, they really do have a "250 year" business plan, and never make fun of the founders light bulb socket :), with engineering departments so conservitivily organized, that for them to support open development of GPL software is really much like the Pope encouraging contraction!

      It makes good business sense to use GPL-ed software when you want to devise a new product.

      1. Low cost or no cost.
      2. If you give geeks a chance to play with it, they can start to tell regular people how it works, why they should get it, etc.
      3. Since most "regular" people don't care or don't want to know why it works the way it does, if the people who care why it works (geeks), show others that it just works, others will be inclined to buy that product.

      The moral: Most people will buy something if it simply works. Sony and Panasonic are letting us make sure it works before they mass-release.

      Great strategy for the companies and I get to fullfil my hacker tendancies!

  • OK,

    Yesterday, I needed to do a side job for a friend and instead of running CAT5, I used some of the new powerline ethernet [netgear.com] stuff. What has me impressed is that this stuff was *dead reliable* and quite compact for its first iteration. What happens when it shrinks and we see this stuff built into TVs and alarm clocks?

    Aside from your toaster manufacturer snooping your toasting habbits, your alarm clock will be able to pull MP3s from the home server. Your TV will pull the funniest commercials (ala the late adcritic.com) from the Tivo ranking database. Create a standard for it all, and you've got some remarkable integration.

    With this, it hopefully will not be called "DirectHOME" or something like that...
    • No, it will be called either $HOME or ~/
    • Create a standard for it all, and you've got some remarkable integration.

      But I don't want my toaster oven noticing that this is the third time this week I've had toast slathered with 1/4 stick of butter and two teaspoons of honey, double checking with the bathroom scale, collaborating with the fridge to lock me out, then instructing my tivo to stop recording the x-files and start recording all those home workout shows and exercise infomercials, then finally telling my puter not to let me log into /. until I do a few situps first.

    • Is it really? It's just more moving parts, more electronics to break. Where is the real benefit, aside from the geek factor, to having your alarm clock play MP3s? It won't give you the weather... or do you pull a weather feed down from the Internet and text-to-speech it? There's something that does that already... called RADIO.
      And who says I want ANY commercials on my TV?
    • So how good is the Netgear kit? I'm guessing it's half-duplex. And does it 'leak' - the spec says 'works across circuit breakers and phases', so can everybody in your friend's street see his data?
      • Yup, that's exactly what it means - I've been evaling similar equipment of late, and basically everything on the same transformer is one network. Also, high noise devices (like vacuum cleaners) dirty up the signal badly. Powerline Ethernet is really very similar to Wireless, security and reliability wise.
    • That all sounds great and wonderful.

      Unfortunately, the power lines in my house aren't even capable of sending the signals X-10 devices* use from outlet to outlet in the same room. I can't imagine getting MP3 files through them.

But other stuff - say DRM - will certainly NOT be under the GPL. Then there's going to be such a hoopla and whining in forums such as this one even though these companies have done exactly what they're obligated to. "They should give back to the community", etc, ad nauseum, and some people will be wondering why, if the open/free software implies some sort of larger obligation to a community, why these weren't written into the licenses.

      You aren't cringing enough. They don't need to keep DRM code closed source. They will simply design the system so it won't run unsigned code. If you make one tiny improvement to the code and recompile, it won't work. You will have no choice but to use Sony/Panasonic code.

      If you find a security hole, you will have to wait for the vendor to fix it. If you want to create software for the system, you will have to get the vendor's permission. In essense, it defeats the whole point of Open Source (putting you control, letting you improve the system, letting you fix the bugs, etc.).

      Of course I'm just speculating. It's possible they'll release the system without DRM, but coming from Sony, I seriously doubt it.

      • It also depends a bit on their DRM structure. DRM is definitely not my expertise, but the frameworks I have seen usually involve some central source that monitors and verifies or denies access, keys, what-have-you. Even if they hand out all the client code, it will probably have to access some DRM server that is not public. Sure, you could change the client code to access some other DRM server, but then you might not be able to get the content you want. Perhaps a free-based DRM framework project is needed?

      Multimedia is a case where openness is more important than it might be in other applications. While there's nothing really wrong with a proprietary player application or having a player run on a proprietary OS, there does seem to be a slight tendency for proprietary software to use proprietary formats, and for open software to use open formats.

      If the designer decides to use Linux, it implies something about their values, which further implies that you will have fewer interoperability problems. The implications can be wrong, of course: it's just a very general trend.

    • Sony sucks. And not just because they're members of ??AA (their film subsidiary is an MPAA member, is it not?).

      Sony makes overpriced, underperforming crap gear in every consumer electronics category. They are only able to sell their junk thanks to their marketing department. The last good, innovative product they had was the original Walkman.

      They can support Linux all they want - I'm happy for Linux if it helps it get more mainstream acceptance (although, embedding it in a consumer product is NOT going to help Linux on the desktop, don't kid yourself). However, I will not buy anything that comes from Sony. I've been burned by their poor quality and lack of support one time too many.

    It seems to me that most commercial PVR's are running on a Linux platform, not to mention the several PVR projects for Linux such as MythTV [mythtv.org] and Freevo [sourceforge.net].

    I use both of these and they both work great (with much tweaking on my part) and I don't have to deal with any of the PVR bs like commercials or having to subscribe.. which makes all the work it took in getting a solution working up more than worth it. If more people would support one of these projects it could easily grow into an easy to use package that anybody can setup in a realatively short time and we can circumvent DRM. "You wanna stick DRM on all the PVR's? Fine, my PC is DRM-less.. do something about it."

  • Sony and Matsushita has both a common ennemy -> Microsoft Microsoft is attacking Sony on their Playstation business, where as Matsushita has very good relationship with Nintendo (they make the mini-dvd player of the Gamecube, and the Gamecube Q)
  • So, why should we? My job is to design, implement, and administer networks for customers. Some of these are quite large networks and some are small but they all have one thing in common: in order to take care of them I have to understand the way all the components work. Ahhh.... I just heard a penny drop.

    I spec Cisco routers and switches because I understand how they work and know that they will do the job. The customer doesn't have to pay me to spend time figuring out how to fix a problem; once I know what the problem is the chances are I can put a fix in quickly. Often without leaving my office! This saves the client money and, not coincidentally, makes me look good.

    If Sony puts Linux into a device then I already have a better chance at understanding how to make that device work than if some engineer had designed his (or her) own idea for a cool command set.

    And because Sony now doesn't have to put all that extra money into designing the OS, that means that their products will cost less. I can put their products into a network and save money on both ends: the procurement end and the administration end. This makes Cisco scramble to lower prices to keep market share. So even if we don't use Linux devices, the costs for networks goes down just because these devices are out there.

    In short, I care what the underlying OS is on these devices because I don't have to learn a zillion different commands for the same things and I can, therefore, do my job quicker and more efficiently. You should care because when you get a job at a company you can hire me to do your network and look good when we save you money.
    • I got so carried away with my own rhetoric that I neglected to tie it in to home electronics so here goes:

      Thirty years ago anyone who understood electronics theory and vacuum tubes could fix any home electronic device. Simply understanding how electronic circuits worked meant that a tech could move from one device to another. And manufacturers didn't have to design a new theory for each device, they just wired up the vacuum tubes in new ways which were still understandable. All a tech had to do was look at the schematic diagram, apply a few standard tools (oscilloscope, VTVM, signal injector, etc.) and he (or she) could make it work.

      So if Sony uses Linux in its latest widget and you understand Linux, you'll understand how your widget works and how to get the most out of your widget. Plus, since Sony didn't have to design a brand new widget-operating-system, you will either be able to buy it cheaper than the Samsung widget or it will do more... or both. And if your widget breaks you won't have to buy a new one, you can just flash the bios and make it just like new.

      So putting widely known operating systems into devices saves money for both the manufacturer and the consumer. This makes us all happier and a few of us wealthier. If you learn Linux, and Linux is the OS they put in all these devices, you have a better chance of joining that few. :)
      • So putting widely known operating systems into devices saves money for both the manufacturer and the consumer.

        Assuming, of course, said operating system can perform the job effectively and efficiently. Thanks to our superb kernel hackers, linux is quite scalable. It works good both on the embedded scale and the supercomputer scale. But one can imagine situations where linux would not be the best solution. In fact, until recently linux wasn't very scalable at all and it would have been a terrible idea to try and use it in embedded devices, even if it IS familiar to most geeks.

        Remember Windows CE? I actually think it is still around, but when it first came out it was vastly inferior to PalmOS. Windows was designed to work on a desktop, not in an embedded device. It didn't matter that it was an interface that was already familiar to a lot of people. It wasn't a good tool for the job.
  • So what do we reckon the chances are of them embedding open source software in secure hardware devices such as SACD players, digital TVs, palladium PCs and set top boxes? I'd say with, for example, Sonys hardware and software interests the chances are less than nil.

    Unusual for Sony to consider going open. Usually they make very propritary technology, such as Minidisc, Memory stick, Magicgate and SACD. This looks a lot like they dont care what they put in their boxes, as long as its cheap. Windows embedded isn't cheap, and it would probably mean adding more RAM too. Just because the systems run linux doesn't mean people will be able to mess with them easily. Its unlikely the appliances will have a convenient RS232 port to plug a terminal into, or a keyboard. People may be able to make some adjustments to the OS, but thats about it. As someone said earlier, even through some code will be released the all-important DRM technology will not. It wont be covered under the GPL as its not part of linux. Without the DRM code and keys the source code wouldn't be much good. You could rewrite sections of the code, recompile, and put it on the drive (or flash a chip for smaller appliances) but what then? The other appliances wouldn't trust it, if it has a hard drive it will be encrypted so the recompiled kernel wouldn't read it. Like most DRM systems it would be an all-or-nothing system. If you really wanted you might be able to recompile a DRM-free kernel and somehow get it to execute, but unless all the other appliances were also rewritten you wouldn't be able to view anything other then your move movies (unless someone breaks the DRM of course) Microsofts response should be quite intresting through. They only have two embedded OS platforms, windows CE and windows XP embedded. Both are a bit on the large side. MS is not going to remove all those fancy skins and 16-bit icons, so they might start marketing more agressivly. Assumeing the whole thing doesn't fade into obscurity, with a complete OS but noone makeing appliances using it, this is certinly good. But dont expect the Microsoft empire to collapse just yet. Like MS, Sony guards its propritary technology carefully. They arn't going to just give away source for playing SACDS or decryption codes for OpenMG.
    • Very true. Using open-source code in part of the design might have the beneficial side-effect, to them, of pacifying people who want to tinker - in the example of SACD players they could for example allow us to use their visualisation API to draw nice pretty pictures to go with the music, but you can guarantee we wouldn't get access to the bitstream itself. Sly buggers.

  • The problem with everyone getting so damn happy about Linux being embedded is that as tough as it is to write Linux apps, it is doubly tough for embedded. And just cause they use it does not mean much. Do you really care what brand of engine is on the jet you ride? No, of course not. Are Sony and company going to open up and let you change their software or they just going to use Linux inside (and slap on a Linux Inside label (made out of all the left over Intel Inside labels))? Look at the great Tivo. It built a great product on top of Linux but about all you can do is upgrade the hard disk [google.com].

  • I think it's great to see more Free Software being released. I welcome more Free Software programmers and their Free Software projects. But I think the importance of freedom is being ignored to chase what's popular and convenient here and now. I also see some potential for mistaking the advances of a freedom-minded movement for the advances of a freedom-dismissing movement.

    From the press release:
    "While Linux is well known as an operating system for personal computers and servers, today it is also finding applications in the area of digital home devices."

    Linux is not an operating system, it is and has been a kernal. The Linux kernal is an important portion of a complete GNU/Linux operating system but it is just a portion (no matter how many people say otherwise) and it's not fair to ignore GNU. There are compelling reasons [gnu.org] to take the time to mention GNU [gnu.org] when you are talking about a complete operating system.

    The great stuff we all appreciate in GNU came from a movement that pays a lot of attention to software freedom. The Open Source movement (which curtly dismisses the importance of software freedom) came over a decade later, well after the GNU GPL had been published and in wide use; well after the pragmatic idealism of the Free Software community had published a lot of Free Software. So please don't misattribute the gains of freedom (both practical and ethical) to the wrong movement.
