mkdir release

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..
make
sudo make install

Cause

I face this problem because I accidentally try to install MongoDB 3.0.x (from http://repo.mongodb.org/apt/ubuntu) while actually a MongoDB 2.6.8 (provided by ubuntu) is already installed in the same computer. Therefore, both mongod and mongo commands are still point to the old version (which doesn't work actually). Since the official installation document said that "You cannot install this package concurrently with the mongodb, mongodb-server, or mongodb-clients packages provided by Ubuntu", this just cannot work.

A better way is to first completely uninstalled the older version before install the new one, but I already missed that time. So

sudo apt-get purge mongodb mongodb-clients mongodb-server mongodb-dev
sudo apt-get purge mongodb-10gen

cannot remove it completely (not sure whether that's the exact case), and \usr\bin\mongo and ``\usr\bin\mongo

My original plan is to setup a good viewing environment for markdown files (analyzing results produced by some template engine). No blog functions are needed. However, it turns out to be tedious and not as useful as expected.

To setup Ruby, basically following this link is fine. Note that rails (or at least node.js) is needed. Pure ruby is not enough.

To setup Jekyll, following this link. After installation, running

$ bundle exec jekyll serve

Tomcat7

Setup tomcat7 is easy. Just do

sudo apt-get install tomcat7

and http://localhost:8080/ will work already. The default source files are in /usr/share/tomcat7, while the default path is in /var/lib/tomcat7/webapps/ROOT.

Basically follow this link will work.

To give access of remote users using postgresql-client, one need to add the following line in /etc/postgresql/9.3/main/pg_hba.conf.

host    all             all             0.0.0.0/0               md5

Run default example:

$ ./gatling/bin/gatling.sh -sf gatling/user-files/simulations/computerdatabase/ -s computerdatabase.BasicSimulation -m

For a minimal setup using https://gatling.io/docs/current/extensions/maven_plugin/, then one can run it using mvn gatling:test.

For using io.gatling.highcharts:gatling-highcharts-maven-archetype, it seems have problem to run inside of Eclipse (I can't "add scala nature" even if I follow this toturial. However, to make it working in IntelliJ IDEA is quite straightforward (add scala plugin is kind of the only thing which need to handle).
