Flash in Ubuntu 10.04 64 bit
Installing Adobe Flash from the repository in Ubuntu 10.04 64 bit gives you the 32 bit version and runs it with nspluginwrapper. I have experienced several problems with this solution in Firefox, and is therefore using Adobes 64 bit Linux version.
Uninstall the repository version of flash
sudo apt-get remove flashplugin-installer nspluginwrapper
Get the Adobes Linux version from http://labs.adobe.com/downloads/flashplayer10_64bit.html and install it:
wget http://download.macromedia.com/pub/labs/flashplayer10/libflashplayer-10.0.45.2.linux-x86_64.so.tar.gz
tar -zxvf libflashplayer-10.0.45.2.linux-x86_64.so.tar.gz
sudo mv libflashplayer.so /usr/lib/mozilla/plugins/
rm libflashplayer-10.0.45.2.linux-x86_64.so.tar.gz
Restart Firefox
Update: June 6th
I have switched back to the "Ubuntu" Flash, because I was unable to use pages from ipapercms.dk:
sudo rm /usr/lib/mozilla/plugins/libflashplayer.so
sudo apt-get install flashplugin-nonfree
The flickering seems to disappear when all the fancy visual effects are disabled.
Cleaning up /boot by removing unused kernels (Ubuntu)
At some point /boot will be full of old kernels (if /boot is a separate partition), which makes it impossible to make a dist-upgrade and it is therefore necessary to remove some old kernels.
Start by finding you current kernel
uname -r
which will give something like
2.6.24-25-server
Now, find all installed kernels
aptitude search linux|grep linux-image | grep "i "
which will give something like
i linux-image-2.6.24-12-server - Linux kernel image for version 2.6.24 on x
i linux-image-2.6.24-14-server - Linux kernel image for version 2.6.24 on x
i linux-image-2.6.24-15-server - Linux kernel image for version 2.6.24 on x
i linux-image-2.6.24-16-server - Linux kernel image for version 2.6.24 on x
i linux-image-2.6.24-17-server - Linux kernel image for version 2.6.24 on x
i linux-image-2.6.24-18-server - Linux kernel image for version 2.6.24 on x
i linux-image-2.6.24-19-server - Linux kernel image for version 2.6.24 on x
i linux-image-2.6.24-21-server - Linux kernel image for version 2.6.24 on x
i linux-image-2.6.24-22-server - Linux kernel image for version 2.6.24 on x
i linux-image-2.6.24-23-server - Linux kernel image for version 2.6.24 on x
i linux-image-2.6.24-24-server - Linux kernel image for version 2.6.24 on x
i linux-image-2.6.24-25-server - Linux kernel image for version 2.6.24 on x
i linux-image-server - Linux kernel image on Server Equipment.
Purge all of these, except the one found with uname -r and linux-image-server, which is a meta package
sudo apt-get purge linux-image-2.6.24-14-server linux-image-2.6.24-15-server linux-image-2.6.24-16-server linux-image-2.6.24-17-server linux-image-2.6.24-18-server linux-image-2.6.24-19-server linux-image-2.6.24-21-server linux-image-2.6.24-22-server linux-image-2.6.24-23-server linux-image-2.6.24-24-server
The above freed 250 MB from /boot and 550 MB from / at my system.
Howto program the Avnet / Xilinx Spartan-3A Evaluation Kit from Ubuntu 9.10
The Avnet / Xilinx Spartan-3A Evaluation Kit is a $49 FPGA kit from Avnet, with a XC3S400A Spartan-3A FPGA, and a number of simple peripherals:
- Xilinx XC3S400A-4FTG256C Spartan-3A FPGA
- Four LEDs
- Four CapSense™ switches
- I2C temperature sensor
- Two 6-pin expansion headers
- 20 x 2, 0.1-inch user I/O header
- 32 Mb Spansion® MirrorBit® NOR GL Parallel Flash
- 128 Mb Spansion MirrorBit SPI FL Serial Flash
- USB-UART bridge
- I2C port
- SPI and BPI configuration
- Xilinx JTAG interface
- FPGA configuration via PSoC®
The flash is not updated through a JTAG, but through the USB interface. On Windows the AVprog is used, which can run in Wine and therefore usable on Linux. It is however easier to use the tool called ASTriAEKiPro 1.2.1.
