No there will not be hardware accelleration because there are no DRI or X11 drivers/modules for it.

And unless the full spec of the GPU is available to very experianced kernel coders (and chances are it isn't, RPis isn't, you need to be under NDA), it will never happen.

Whats this then?

Is there any chance of getting flash to work on any of these things?

I know I am probably asking a bit much, butI'm not looking for video playback or anything.

Just basic flash apps that stream audio (as that is what the football club I support use to stream live commentary of their games).

They can't iron out performance bugs, it doesn't have the CPU power.

Apple TV 3 which has 1Ghz Apple A5 chip struggles with XBMC, Boxee Box runs a 1.2Ghz Atom. RPi has 700Mhz CPU and has no chance at running XBMC smoothly.

This is not correct...

NONE of the current OS releases for the RasPi take advantage of the GPU and many other components. Raspian is the first to use the hard float part of the CPU. Additionally there is a USB issue which causes it to use 20% of the CPU even with nothing plugged in (and ethernet goes over USB).

There is MUCH to be done on the PI to make use of the hardware and free up the CPU.

My RPi is ok but very buggy at times and needs constant reboots. I know this is due to the OpenElec build I'm using (I'm using mine as an extender to my XBMC machine downstairs), but I think it will always be lacking.

What mA (mAh) power supply are you using? I was having problems with my Pi at first and then realized I had swapped the 700ma I had intended to use with it with a 550. You need a 700-1200ma for the "B" Pi.

Crap. Would 750mAh be enough for a "B"?

XMBC is running fine on mine with Raspbmc RC3, the only problem I have had has been my own broadband speed, so streaming internet media like iPlayer stutters a bit.

Should be. A sign that it isn't is when your USB suddenly stops working and/or ethernet lights go off, then come back on a short time after. In my experiences though, the USB devices never reconnected :( and therefore, hard reboot.

It's a 1000ma

Should be plenty, but see the above. Otherwise... SD card speed? I mean granted it is a 700mhz ARM processor, but aide from a few hardware things, we'll just have to wait for the software side of things to catch up.

I'll do a DD of my SD card later and put it up.

I don't know why people think the gooseberry is any better, it has NO HARDWARE ACCELLERATION AT ALL if you get linux on it. All it can do is the same as the RPi for decoding h.264 or whatever they've licensed, if you put X11 on it and try to run even fluxbox, it will be so slow it's unusable.

Well the Gooseberry is quite useful if you want to tinker with Android I suppose.

Smooth ICS tinkering for <100 bucks? Hell yeah!

Can you release uncompiled code, too?

That would be hot! :yes:

Where did you get Gentoo for Rasberry anyways?

Not been actively researching alternatives to the known candidates myself so far, so might have missed obvious sources! :laugh:

I never got QEMU going in OS X so used an Ubuntu VM with QEMU to play with.

Joy!!! :laugh:

QEMU Team, fix yer Mac code! :p

This is not a hardware issue.

It's a social issue, infiltrate them and change their IT strategy! :p

Other than that: good luck, brave man! :laugh:

(Could wirk, wouldn't install that sucker Flash myself though! :D)

Crap. Would 750mAh be enough for a "B"?

Official PSU has 1200mAh, which probably covers powering the USB a bit, so should be OKAY, but expect no flawlessness when hooking up stuff that draws a little power.

Noted. Should I ever make it to be a mod, thou shalt feel my wrath!

Whilst that's better than what RPi provides, 'Note that these components are not a complete driver stack. To build a functional OpenGL ES or OpenVG driver you need access to the full source code of the Mali DDK, which is provided under the standard ARM commercial licence to all Mali GPU customers. For a complete integration of the Mali DDK with the X11 environment refer to the Integration Guide supplied with the Mali DDK.'

Someone uploaded the gentoo image to the raspberry pi forums a few months ago (contury to belief, gentoo was the first hard floating point release for the pi, not raspbian) so I took it and got a lot more compiled for it!

It's an 8GB image so I errr need hosting for a large file... Ideas? :p

And it doesn't come with source but it's got the full portage tree so if you want anything compiled you just do an emerge of it

I'd be immensively interested in the source code, but oh well...

We could create a torrent for it?

Also we could put it on a good old FTP. :)

Finally got around to placing my order ;) Now lets see how long it takes to actually get here

post-14624-0-06501200-1342463438_thumb.j

The cable they had listed for the power supply was only 0.5 meters - thats pretty freaking short. I found one that is 2 meters elsewhere, and the cases they had were crap -- there were some really nice looking ones posted earlier in the thread. So going to order one of them I think.

Should be here in time to start to play when the weather starts changing ;) heheeh

edit: The cool cases where in another thread, ended up with this one - just placed the order

http://www.adafruit....s/859#tutorials

The other one is from company in BE, which looks freaking sweet! But problem is at 13 euros for shipping, plus 21% vat plus its price your looking as spending more for the case than the actual Pi ;)

I've not really been a fan of clear cases, but that looks sweet. The thickness of the acrylic makes the quality stand out.

Just about to have a play with this emulator and image, learn a few basics before it arrives for real :)

http://sourceforge.n...rpiqemuwindows/

nice, have been looking for a windows version. I was trying to set it up manually with no luck. There is also a Virtualbox/VMware Ubuntu disk images with an out of the box working QEMU setup http://www.raspberrypi.org/phpBB3/viewtopic.php?p=39289#p39289

You can change the image in that link for any of the images on the RP site, quickest way I found was just to name the new image the same as the old one and copying it into the emu folder in place of the old image

Anyone know of any plans for BSD to arrive on Rasberry Pi?

That would be awesome and I wouldn't think twice before installing it as main OS.

Gah!!!!!!!!!! The power supplies that I ordered aren't even close to being correct. FUUUUUUUUUUUUUUUUU

Does anyone have a part number for the correct power supply that works with the B revision?

No idea sorry but I plugged mine into the routers usb port and it's been fine if that helps.

I just used my mobile phone charger and its been working fine for weeks, but then I don't own an iPhone with its crazy connector just a standard usb micro charger that all my phones usually use

    • Nearly half of American adults now use AI, but concerns are also growing

      By Hamid Ganji · Posted

      Nearly half of American adults now use AI, but concerns are also growing by Hamid Ganji Since the launch of ChatGPT in 2022, the way people research, get their news, and perform routine tasks has changed dramatically. Now, almost everything around us has a touch of AI, and companies are trying to embed it into nearly every product and service they offer. With that in mind, new research shows how Americans are actually adopting this change and using AI in their everyday lives. According to new research conducted by the Pew Research Center, 49% of American adults now use AI chatbots like ChatGPT or Gemini. This marks a significant increase over last year, when only 33% of American adults reported using AI. Additionally, four in ten U.S. adults (42%) said they use AI tools to research information, while 38% said they use these tools to handle tasks at work. Entertainment, image and video editing, and getting medical advice are among the other ways Americans are using AI. Moreover, ChatGPT dominates the U.S. AI market, with 44% of respondents saying they use OpenAI's chatbot. Gemini follows at 24%, while Copilot and Meta AI account for 17% and 14%, respectively. Respondents also said that AI chatbots generally have a positive impact on their productivity and how informed they are. But when it comes to AI’s impact on society, Americans remain largely skeptical. About 40% of American adults believe AI will be more harmful than beneficial to society over the next 20 years. Additionally, 31% expect AI to have a negative effect on them personally. Another 31% of respondents say AI could be equally positive and negative. As for data security, pessimism remains high: 71% of respondents say AI will make their personal information less secure, while only 3% believe it will make their data more secure. American adults also largely lack confidence in both the government and AI companies when it comes to regulating and developing AI. About 67% of Americans have little to no confidence in the U.S. government’s ability to regulate AI effectively. Six in ten adults are also not confident that U.S. companies will develop and use these tools responsibly.

    • Latest Rufus update improves new Windows 11 install method

      By TarasBuria · Posted

      Latest Rufus update improves new Windows 11 install method by Taras Buria Pete Batard, the maker of Rufus, a very popular app for creating bootable Windows (and other OS) media, has released a new beta version of its app. Rufus 4.15 beta is now out, and while it offers no new features, there are all sorts of improvements and fixes, including for the new Windows 11 installation method that was introduced in version 4.14 in early May. The "Silent Windows 11 installation" is a new feature whose goal is to automate operating system installation. All you have to do is boot from the drive, and then Rufus takes over, doing all things for you, such as setting up a new account, skipping ads and prompts, and more. It is a very handy tool, but initially, it had some bugs and issues that required addressing. With version 4.15 beta, Rufus is fixing that, particularly a bug with installation failing at 75%, crashes on Snapdragon X-based PCs, and more. Here is the changelog: Rufus 4.15 beta is now available for download from its GitHub repository. If you have never used Rufus before, you can check out our guide here. It is a very useful utility to have, as it allows you to deal with plenty of Windows 11's annoyances, which are still there, despite Microsoft's ongoing efforts to fix them.
    • Microsoft fixes one of Excel Copilot's most frustrating limitations

      By Usama Jawad96 · Posted

      Microsoft fixes one of Excel Copilot's most frustrating limitations by Usama Jawad Microsoft began integrating Copilot into Excel a couple of years ago and has been upgrading it with new functionalities since then. While some changes have been controversial, Microsoft is hoping to win over users by allowing them to be more productive via Copilot. To that end, it has now announced a Copilot improvement that may actually be appreciated by people who use it regularly. Excel customers often use the Copilot prompt box to issue instructions to format and customize their data, but it can become quite tiring to keep repeating the same instructions again and again. Microsoft now allows you to define Copilot personalization rules for formatting, naming conventions, formulas, and report styles. These can be accessed via Settings > Personalization, where you can explain your rules in natural language like "Always format currency in USD with no decimals", and just let Copilot take care of the rest. Microsoft is going a step further in this direction by allowing you to set workbook rules too. These rules are stored as a .Rules sheet, and are preserved while the workbook is shared. This fosters collaboration while making sure that standard rules govern the Copilot editing experience across the organization. Other advantages of this capability include pointing it to specific examples, defining dynamic formulas, and referencing an entire sheet and asking Copilot to infer rules based on that. You can leverage this feature by opening Copilot in Excel, clicking on "+", and selecting Create workbook rules. If you have an existing .Rules sheet, you can simply start listing the rules in column A as well. Personalization features are available to all Copilot in Excel users across the web, Mac, and Windows. Meanwhile, workbook rules are currently being previewed for Windows and Mac customers on the Insiders channel. General availability is scheduled after a few weeks, but a concrete date is currently unknown. Overall, the Excel capability is quite similar to ChatGPT's memory features, which allow you to permanently store items in the AI model's context window.
