Re: Raspbian - SD card space

On first boot raspi-config is started and lets you choose to automatically expand the partition to the full disk size. It's then resized on next boot (and may take some time).

Re: How to block IPs that fail to SSH?

I'm not using Raspbmc but as I understand it's a Debian system 'under the hood', so you should be able to install fail2ban. Fail2ban does exactly what you want. It scans several logfiles on the system periodically and recognizes failed login attempts, parses the ip address and blocks it for a certai...

User / password and internationalization

Just al little hint for all you diligent distro builders: It would be really cool if you could unify username and password in Pi land (something like pi / pi, easy to type, easy to remember even if not secure), so people (a lots make their first steps in Pi and Linux land) don't get confused with al...

Re: l1/l2 cache

The L2 isn't split. Don't think of the BCM as a ARM core with GPU. It's the other way around. The L2 belongs to the GPU and may be made available to the ARM core as well, but the path is rather long and if you do graphics intense stuff you'll shoot yourself in the foot.

Re: GL performance

Any benchmark is good as long as you know what exactly you are measuring. As people already said, glxgears is software-ony and the X driver isn't optimized, either. So this benchmarks is some kind of a simple real world benchmark for completely unaccelerated 3D. Low-level benchmarks may reveal the p...

Re: GPU Processing API

The real problem is when the hardware goes into EOL and all support from broadcom will vanish and users are stuck with binaries that will break with other open source software (i.e kernel and X) that continues to advance. So it all comes down to the real problem being a problem of many ifs that lie...

@JamesH

I'm not an expert in this, but isn't what you tell about BC's perspective on why to keep things secret like if you said anyone could make their own similarly energy efficient ARM core clone just by looking at the architecture reference manual?
Is reverse engineering really that "easy"?

Hi there! While I really like the new forums I notice the absence of a breadcrumb. When you are browsing a thread there is no way to get back to the topic list other than the browser's back button.

Re: Included Setup and Softwares on next release..

I think the better way would be if distribution maintainers / developers programmed a setup tool that launches on first startup (in text mode) to allow people to do some basic settings like keyboard layout, language, startup mode, screen resolution, network settings, etc.

Re: GPU Processing API

I agree with the implication that this is less than ideal for education. It's especially bad in that any problems that are found in code that touches the closed hardware cannot be fixed by the open community, nor can improvements be made except under NDAs with a single company. That's bad on multip...

Re: Best first language choice

C++ is not very similar to Objective-C. ObjC ist simple, lean and elegant. C++ is a beast ;)

Besides both sitting on top of Ansi-C their designs don't look too similar. It's like comparing Java to Smalltalk, though Gosling borrowed some ideas from Smalltalk when he created Java.
