Sometimes you want to ssh to a machine, leave a process running there and exit. Screen allows you to do that:

$ screen
$ sh myscript.sh
[type Ctrl+a+d to detach window]
$ exit

The process won’t stop even if you close the ssh session.

An interesting read on Virtual Machines http://amzn.to/98HWn4

The other day I found a very interesting reading list made by Intel that includes recommended books from different technological areas (HW, SW, parallel computing, etc.). If you’re working on any of these topics, it’s worth taking a look.

Object Oriented C? Sure. In the end what’s important about object oriented programming is the techniques not the languages. If you are interested on the topic take a look at this book.

Certainly, one of the main strenghs of Linux is its powerful shell. A few years ago Windows lacked a competitive counterpart. This doesn’t seem to be the case anymore, thanks to Windows Powershell. By now I don’t have enough info to give an opinion, but it’s something I want to look into. I’ll be back with more information when I play a little bit with it.

If you want to know which RAM is installed in your PC (DDR, DDR2…) and its speed, type this command:

$ sudo dmidecode --type 17

Remember that dmidecode can provide additional (useful) information about your HW.

If you are going to develop Verilog/VHDL code using eclipse I’ve got good news for you. Veditor provides a nice environment to work with Verilog. To install it click Help->Install new software. The repository URL is at:

http://veditor.sourceforge.net/update

Be sure to uncheck Group items by category, otherwise Veditor won’t show up.

First go here and choose your operating system and architecture. Download the corresponding jre.

$ chmod +x jre-6u16-linux-i586-rpm.bin
$ sudo ./jre-6u16-linux-i586-rpm.bin

Probably your system has another java version already installed:

$ java -version

If this is the case select the new jre using alternatives:

$ sudo alternatives --install /usr/bin/java java /usr/java/jre1.6.0_16/bin/java 2
$ sudo alternatives --config java        #choose 2

To check that the selection has worked:

$ alternatives --display java
$ java -version
