Boost is a very extensive C++ library. To compile + install:
wget http://heanet.dl.sourceforge.net/project/boost/boost/1.55.0/boost_1_55_0.tar.bz2 tar xz boost_1_55_0.tar.bz2 cd boost_1_55_0 mkdir ../boost ./bootstrap.sh --prefix=../boost ./b2 install
Sometimes when you try to suspend the Ubuntu operating system, it wakes up immediately. This is often because certain devices are in “awake” state. To fix it, first you need to find out which device it is. Do:
acpitool -w
You might see output like the following:
Device S-state Status Sysfs node --------------------------------------- 1. P0P1 S4 *disabled 2. GLAN S4 *disabled 3. XHC S4 *enabled
To disable ‘XHC’, do:
echo 'XHC' > /proc/acpi/wakeup
with superuser privilege.
Typical suspects are USB devices. To find out the USB devices in your system, do:
lspci | grep USB
It’s easy to block specific domains on Linux. Just open /etc/hosts and append the following lines:
127.0.0.1 facebook.com 127.0.0.1 www.facebook.com
(replace facebook.com by the domain name you wish to block)
If you want to monitor the network traffic on Linux, do:
netstat -ctupW
gThumb is my favorite image viewer. However, gThumb 3.2.7 (which comes with Linux Mint 17) has a bug where only one instance of gThumb is allowed. See this bug report. The suggested solution is to use gThumb 3.2.8 which can be grabbed from the Ubuntu 14.10 (Utopic Unicorn) repository.
So, download the .deb files from:
– https://launchpad.net/ubuntu/utopic/amd64/libexiv2-13/0.24-2ubuntu1
– https://launchpad.net/ubuntu/utopic/amd64/gthumb/3:3.3.1.is.3.2.8-0ubuntu1build1
– https://launchpad.net/ubuntu/utopic/amd64/gthumb-data/3:3.3.1.is.3.2.8-0ubuntu1build1
Then, install them:
sudo dpkg -i libexiv2-13_0.24-2ubuntu1_amd64.deb gthumb_3.3.1.is.3.2.8-0ubuntu1build1_amd64.deb gthumb-data_3.3.1.is.3.2.8-0ubuntu1build1_all.deb
Problem solved. =)
