    My guess is that centrafuse does some bad P/Invokes to unmanaged code or windows services that make it less than cross-platform friendly.

    Second issue with CF on ARM is that CF is notoriously slow. VegasGuy has an i3 over an atom for a reason and my guess is that's one of the biggest reasons. Mono has an ancient garbage collector that makes things even slower. Maybe things have changed in the last time I checked but this would make something slow even slower running on Linux and slower still running on ARM.

    RR is probably the same story. Porting it to Linux shouldn't be too difficult.

    The openMobile folks aren't ignoring these systems. They've got a lighter faster version in the works and they are playing with a couple linux distro's to create an instant-on type system
    Just need to throw in some corrections here....
    rr is written in vb6 not .net..... it cannot and will not ever be ported to linux.
    cf doesn't just have a few pinvokes it relies on windows media player and directx.... there would need to be a large and massive rewrite of the core to get it to run on something other then windows (wince is part of the windows family).

    Now as far as the speed goes...all front ends other then OM use the CPU for graphics which would put a large burden on the arm processor....once video and graphics are offloaded to the gpu and music decoding is offloaded to the sound processor you will find it has more then enough CPU available for whatever you need. Lets not forget an ARM cpu powers the ipad and numerous other not-exactly-slow tablets.

    Right, RR is in vb6... I thought for some reason they were converting it over slowly to something less ancient.

    CF uses directx and only software rendering? That seems silly.

    Does the current version openmobile run on Linux? I can't find any downloads later than 0.5?

    Mal already answered the "no, windows is not a mere 109 dollars".

    For BugByte, teething problems like that nowadays are actually pretty uncommon. It may be hardware-related?

    Overall, I understand that there are lots of valid reasons that ARM boards may not be the future of car computing. But I'm getting the feeling that it's being dismissed out of hand by people who haven't actually tried it. I use a lot of OSs in my daily life, on a huge variety of hardware. While not all of them are appropriate for all jobs, that doesn't mean I dismiss them without fair consideration each time I need to do something.

    Also possibly of consideration to VegasGuy; you have lots of USB devices right now. You *need* a powered hub no matter what. Something like this would probably be good so you can individually power them. More to the point, though; list all your devices. There's a good chance that a lot of them can be replaced by stuff that actually comes built into a lot of these modern ARM boards. Things like bluetooth, wifi, sd reader. The devoted hobbiest could reduce their devices even more by using the expansion stuff on the board

    Maybe not *these* ARM devices, but lower powered (watts not computing) and smaller with more features *are* the future of car computing.

    directx is only for rendering effects...everything else is software.

    The 0.8 build runs on linux (its posted in the 0.8 thread) and the linux specific media player is also posted further down in the thread.

    i believe that this had been touched on before..

    linux has a very steep learning curve for hardware guys like me-- that is the problem with linux based setups and, because most ARM based solutions usually run some form of linux, my problem indirectly falls on ARM processors.

    that is not to say that i can't learn, but it could take a while longer then my attention span.. esp. when windows does it with fancy graphics... and a easy installation...

    i think that it says something when most would rather purchase a os(that has glitches) for $100-$200 then to even consider a free-os option..

    from there, we get into "why would someone rather purchase a os for any amount of money when linux is free?"

    as i stated above, windows does it in a elegant graphical way(even if it is glitchy), and most people do not even know what the command line does...(i have to enable it in my fresh installs of win7!)

    people prefer graphics to lines of words...

    if linux could be made more 'user' friendly, and less tech friendly, i think many more people would jump on it..

    Linux as a desktop operating system is braindead simple to install and has been for several years now. It's no different than win7 in that sense -graphical blingy installers and all. Embedded Linux is another story. But like I mentioned before, it's really well documented. I followed the step by step howto on getting meego running on the igep and had it up in a few hours and most of that was unattended building of the kernel and OS from scratch. Now, if said stuff were created for you (like it likely will if I get my way), it'd be just a matter of copying it to your sd card and jamming it in the slot. I know you can do that soundman .

    PS. On a side note, Linux is arguably easier to install on the desktop than windows is. After Linux is done installing, sound, networking, wifi, office applications, web browsing is all ready for you to use and you don't have to click through 50 "do not show me this again"-dialogs to get to a usable desktop.

    When did you last try it? This has been incorrect for several years now.

    I also concur with trip's point about hardware. Nowadays I put the CD in and when it's done installing, I have all my hardware supported.

    Some hardware examples:
    When was the last time you used the graphics drivers that came with windows?
    Not only that, but the ATI or NV drivers... Why do my graphics drivers clock in at eighty meg? Why do they put their own icon on the right click menu on my desktop? And a system tray icon?


    I have an Oki C5100N at home [I love that printer]. To get it working in Linux, I said "find a printer". Then I said "yes" when it asked if it had chosen the right thing. Installing that same printer on windows [yes, including XP, Vista, and 7] is:
    1) Go to oki's site. Dredge through their archive looking for driver.
    2) Download driver. Extract by running executable.
    3) Try to add printer. Wait patiently for the windows add printer wizard to finally realise it doesn't have the drivers and can't find them on windows update.
    4) Find "have disk" button. Find where drivers were extracted on disk. Hope I choose the correct driver out of the three it finds, none of which are labelled "64 bit windows 7"
    5) Afterwards, go back on my disk and route around to delete all the cruft that got expanded in step 2.


    I could come up with examples of things like this all day. Seriously, we are *past the point* where "linux is difficult I don't want to learn the command line" is a valid statement. Hell, try it! Go download VirtualBox and a user friendly distribution of Linux, and *try it*.

    I've got to chime in here too.

    I've got a handful of "computer stupid" clients that can't seem to stop infecting their windows machines with spyware/adware/virus/porn. Loaded up Ubuntu on 3 of them now, and have only had one issue that was actually RAM related. So far my clients are eating linux up... especially in this day and age where just about every "bad" site and/or screensaver will get you infected.

    +1 for that. I'm sure of it.
