Re: Feature request: New PS1

Yes, I see. That is unfortunate. Guess that is mostly for Red-green colour blindness though.

Feature request: New PS1

I'd like to propose the following PS1, as the colours kinda remind you of a Raspberry. PS1='${debian_chroot:+($debian_chroot)}\[\033[01;31m\]\u@\h\[\033[00m\]:\[\033[01;32m\]\w \$\[\033[00m\] ' It also makes it easier to recognize when you are logged into your Pi, since the current colours are defau...

I agree. I've suspected for some time that network activity happens always, even though there is no need.

Re: Python is barely usable on Raspbian

Great!
The first run is always expected to be a bit slower (because things get cached here) , but I'm unsure if top makes any difference.
Does it make any significant difference with only one ssh session and no top?

Re: Python is barely usable on Raspbian

You have a Pi B+. The Pi 2 has more memory and a quad core processor. If you want decent performance you should get a Pi 2; browsing and LibreOffice use are acceptable on the Pi 2, but not so much on the Pi B+. I don't know about Python programs.

Re: Python is barely usable on Raspbian

My Pi2 executes the python3 script in 0.246 seconds. About 17 times slower than my PC which cost 45 times as much, and uses about 150 times as much electricity. The Pi2 is a bargain! Could you try to run $ time pip -h and $ time pip3 -h if you have Python 3, and post the times from both machines?

I have raised this issue with pip as it seems this issue is not unique to the Raspberry Pi.

Any news on this?
It's killing me how slow pip is just to show the help message, or doing a simple freeze.

Re: Sainsmart 3.2" (SSD1289) framebuffer driver

Finally, I have one of these modules on the desk beside me as I write this, and I can tell you with 100% confidence that the slot on the module is for a normal SD card. The slot is very definitely not MicroSD, regardless of what the Sainsmart web page might say. That's really weird. Form the pictur...

I not aware of anyone having hooked it up to the RPi file system, but I'm sure it is possible to do so, so long as the module header signals are hooked up.

D.
I meant to ask why it has a MicroSD socket, but I can see I misspelled it. So, why does it?

Re: Prevent SD-Card Corruption

I usually get corruption when updating Raspbian over SSH. Especially if I have two SSH connections open and have

Code: Select all

open in one and run the update in the other. I have two Pis that do this. One is rev. 1 and one is rev 2.

Ok, I just read at some point that overvolting > 0 would be enough to set the bit, and void the warranty.

In the light of recent news (http://www.raspberrypi.org/archives/2008), I'd like to be absolutely sure: Do I lose my warranty if I overclock the device with overvolting?
