Well, that's a shame, xbian was working very well for me. I didn't realize there was an issue with GPL violations.

Judging by Koen's reactions, he sounds a bit immature to be leading such a project. So what's the consensus on raspbmc vs openelec. I tried raspbmc a while ago and was frustrated by the unresponsiveness of the menus. I guess this turbo update should hopefully fix all that though. I haven't tried openelec yet

Nothing special (that I know of). My media server is currently still a Windows 7 box, so I am testing out some goofy german NFS software, but it actually seems to work well.

And also, that sucks about Xbian. Looks like I will be using my other SD card to test out openelec.

Is OpenElec any good?

Edit: I take it I would need the generic install? How difficult is it to get it all running properly?

Honestly, just go with Raspbmc. It's identical to XBian, and like the post regarding the GPL stuff says, it's mainly the higher OC in the XBian config.txt that makes it feel faster. With the dynamic overclocking firmware added to RC5, it should be perfectly usable, since even RC4 seemed fine when I tried it last week.

Here are instructions to install the RC5 version of Raspbmc. I'm gonna give it a whirl later and see if it's as quick as xbian, otherwise I'll probably stick with the last stable release of that until something better comes along.

I wrote up a how-to to make a Raspberry Pi work with the Motorola Lapdock here.

The basic gist of it is to buy adapters off of eBay from Hong Kong and then split a USB cable to break-out the data from the power.

The Lapdock only costs ~$50 and can be repurposed for other projects since it's more-or-less an HDMI screen with a keyboard/trackpad/usb hub/battery.



I hate you. I just spent $75 on a Lapdock + the cables. Can't wait to get a sub $100 laptop going.

If anyone else is interested you can get them for $50 from here just has an english and hebrew keyboard instead.

Looks like they got rid of the base.img.gz in that guy's link, but I found another mirror here:
http://mirrors.arizona.edu/raspbmc/downloads/source/

Once I found the mirror, I followed the instructions and they worked just fine. You can configure all the new overclocking stuff from the Raspbmc Settings tool under the Programs menu. It defaults to Fast for the CPU speed. I bumped it up to Super, and the menu speed is noticeably snappier. I didn't go up to Ultimate yet, since my SD card has corrupted itself before when I was OCing the RPi manually.

I'll get it all configured, then take an image before I bump it up again.

Ultimate locked my pi up as soon as it loaded the background for xbmc, and apparently editing config.txt back to the default settings doesn't fix the problem so I'm going to have to reimage it from scratch :suicide:

Luckily I didn't bother to add my shares just incase this happened but still, looks like super is the best setting for now

Just create a sources.xml / advancedsettings.xml file?

That way essentially you can reimage as often as needed and only copy your config files across. I've found this super easy with openelec as by default is creates an smb share to simply drop them into ...

raspbmc i think takes a bit more fluffing about, but otherwise works well.

That's a much better idea, thanks.

Related, I've decided to go back to the last release of xbian until they release a final RC5 of raspbmc because it's been unstable as hell so far, with or without overclocks. Keeps locking up when trying to open random videos and the mouse cursor stutters like crazy when it's been idle for anything more than a minute.

So I tossed my idea of running Transmission on the same Pi as Xbian and things are working great. I have a 1TB NAS running off of my router which is also running Transmission. The Pi is running as my HTPC and I originally had an issue with DTS audio causing issues with buffering for video but with an overclock it is no longer an issue. My TV does not support DTS decoding and my surround setup is out of commission currently so I have to do it on the Pi. Here is my config.txt:

code:
force_turbo=1
current_limit_override=0x5A000020
over_voltage=6
arm_freq=1050
gpu_freq=300
core_freq=400
sdram_freq=500
The Pi runs at ~68C, I believe under 85C is where you want to keep it. Interesting thing is that the temp actually drops when going from the Xbian GUI to playing a movie/video.

Just thought I would toss this out there for anyone having a similar issue. At some point I will grab another Pi specifically for a NAS/Torrent machine.

I'm considering getting one of these to use as a basic HTPC. Nothing special, I know, but I want to make sure it'll work the way I want. With a USB hub I want to to connect a wireless mouse and keyboard (separate adapters), a wireless card, and an external hard drive. Can I expect smooth H.264 1080p playback from the HDD with this setup, or will USB bandwidth/overhead be a problem? Any issues I might be overlooking?

Also, any suggestions for a VESA mount case?

So my Raspberry Pi just arrived and I realized I don't know what to do with it. I'm mostly looking for something that would involve a bit of low level programming and I've sort of glommed onto the idea of making a simple OS for it.

Beyond that, I also thought I'd like to try to take advantage of the fact that the Raspberry Pi is so small AND has a GPU on board. I was thinking of taking advantage of it for things that require a lot of parallel computations and would benefit from the small form factor but what such a thing is is currently escaping me.

You can't do GPGPU stuff on the PI at all. It's a proprietary chip, and broadcom's binary blob doesn't expose any general processing functionality at all.

It's still useful for normal GPU stuff - scaling, rotation, basic 3D, whatever. You just can't use the GPU for computation, because it's low-power fixed-function hardware designed to run a UI or simple 3D apps/games rather than be a massively parallel vector-ish general-purpose processor.

In general, the RPi is useful as a frontend - if you want to do anything like serious computation, that's what the Ethernet port is for. Farm it out to something faster. The RPi is smart enough to take prebaked data (queries on an external database, pre-baked stuff on the SD card, or whatever) and wrap it up in a nice UI, just like a typical smartphone app. That's enough to enable a lot of interesting use cases if you embrace the device-as-frontend model (want to do heavy-duty math? Sure, it can work - buy some Amazon EC2 time, throw Sage or Mathematica or something on there, and connect to it through the RPi). But, it's not going to ever be a computing device in the number-crunching sense.

That's not really an OS; it's more a "how to talk to the hardware directly" tutorial. It can't load outside code, let alone provide it with services and an abstraction layer.

If you're in the UK, don't try to order your Pi from RS Components. I placed an order for three in July and the order confirmation at the time said they would arrive by mid-september. They still haven't arrived, and after phoning up all they'd tell me is the current lead time (end of November). They had no idea when the ones for my July order would come in.

Really wishing I used Element14 now. It's frustrating to see people who ordered way after me and have theirs already.

One idea that I was tossing around was attaching a webcam and an RC car/USB foam missle launcher or something that can move on its own while leveraging the GPU for something. So I'm not looking for a ton of parallel computations per se, but an application that would require a moderate amount of GPU work that was 'mobile' (so in this sense, taking advantage of the small form factor).

It's not actually fixed-function - you can write shaders for it (and it's reasonably fast for that, comparable to the previous iphone iirc). What isn't there is driver support for OpenCL or whatever.

If you have a specific project in mind, you might want to buy hardware to support that project. If you buy a piece of hardware on impulse, you might want to limit your project ideas to things it can actually do. Yes, there's a GPU on there. There's also a GPU on the Geforce 2 MX knocking around in the back of my spare parts box. As it turns out, if something's called a "graphics processing unit," that doesn't mean it's necessarily suited for general-purpose work, or even very fast by current standards.

Equally as awful as any device. Period.

Now stop making me want to stroke out at the ripe old age of 32. I'm not just talking at the person i quoted here, but seriously, just stop.

Worst case scenario with wifi is like 3 things;

1- you look like a noob to your post-secondary frat-buds when you wire up while they wifi.
2- you spend an extra $36 dollars at monoprice for enough cat-#.
3- you spend another $3 or $4for a strip of tape to match your baseboards so you can run $36 worth of cat-# to your destination.

You have some pre-defined notion of what a server is supposed to be capable of doing and rigidly applying that to every situation. My VPS tends to choke on more than a simple website, too, but I don't care because -- get ready for this -- I don't host any websites on it!

I am not suggesting any particular use for someone's colocated Raspberry Pi. Rather, I am assuming that anyone who would consider such a thing would understand the limitations of both the hardware and the uncertainty of the longevity or quality of the free hosting.

Yes, if you attempt to migrate your business's $thousands worth of infrastructure onto a $35 anemic computer with free hosting, you are a special person, but I don't believe anyone anywhere is considering it or suggesting it.

So i can buy an rPi, sd card, and sufficient power cable, and ship it to austria where it'll be hosted, in what i assume must be a reliable and trustworthy datacenter, for free, then shipped back to me when i say boo?

This DC would also have no issue if i were to set up FDE, as they aren't actually supporting my device?

Honestly, my sarcasm is beyond my control at this point, as i fail to see what benefit such a venture would net a rather innocuous host in Eastern-Europe.
