Install Transmission 2.74 on Ubuntu 12.04/12.10 (PPA and procedure manual)

If you want to use the PPA, below find the instructions to import and update Transmission. At the time of this writing, however, they are still outdated:

sudo add-apt-repository ppa: transmissionbt / ppa sudo apt-get
update sudo apt-
get install transmission

Since the PPA still pointed to the old version of Transmission, proceed with the installation manual by source. Before proceeding, however, I want to remind you that you can safely wait Transmission is updated within the Ubuntu repositories and update the system easily using the command

sudo apt-get
update sudo apt-get dist-upgrade

If you’re like me, and want to get programs from your system immediately up-to-date , follow the instructions below! First install a little ‘dependencies (yes, we’ll need it) and download the source tarball of Transmission, with the commands

sudo apt-get install automake build-essential autoconf libtool pkg-config libcurl4-openssl-dev intltool libglib2.0-dev libevent-dev-dev libminiupnpc libminiupnpc libappindicator-dev-dev checkinstall
cd / tmp wget
http://download.transmissionbt.com/files/transmission-2.74.tar.bz2
xvjf tar transmission-2.74.tar.bz2

At this point, let us go into source directory, compile the program and …. use checkinstall to install it, so you can comfortably manage in the future by USC / gdebi / dpkg / apt-get / aptitude

cd / tmp/transmission-2.74
. / configure
make
sudo checkinstall

At this point we do not need the source directory (which will be deleted automatically when you restart the system), but it is a good idea to keep a copy Package. deb, so you can easily reinstall if necessary. I will put on my desk!

cp / * tmp/transmission-2.74/transmission. deb ~ / Desktop /

Enjoy!

How to save namespaces of XML in dictoinary in Python and Lxml

I have a XML file with many namespaces:

 xmlns:ser="https://some_address" xmlns:mirror="https://some_mirror_address"/>
    server="some_server_address"/>
    default="some_mirror_address"/>

I am using lxml and python to this type of file. Now, My requirement is, When I parse this XML file I need to store all namespaces in a dictionary like:

nsd = {'ser' : 'https://some_address', 'mirror' : 'https://some_mirror_address'}

The intention of this, the namespaces are not predetermined. So When I parse the XML I need to store all the namespaces in a dictionary and then proceed with further activities.
Is this possible to achieve in lxml?

Why would sbt reload gen-idea use 6GB of memory?

I'm using the command

sbt reload gen-idea

to build a largish (hundreds of thousands of lines of code) IntelliJ Scala project.
After about 30 minutes+, the program is autokilled because it runs out of memory. I checked, and it used 6GB before getting killed.
What's going on? Can I do anything to improve this?
Thanks
