Importing Data into Neo4j

Importing data into Neo4j has two kinds of conditions, either installed into a fresh new instance of neo4j server, or into an existing server.
Into an existing server requires more effort and it is should be the technically challenging issue.
In this post, we only focus on the former.

Maxdemarzi’s blog left us a detailed steps of importing data as a fresh start, with the tools provided by Michael Hunger.

It should work as smooth as you could expect.
I am just going to log what I found troublesome.

Installation of Phabricator

This post records my procedure of installing Phabricator (P for short).

mkdir /usr/local/phabricator

install_ubuntu.sh

Till this far, P is installed, but configuration is more important.

First, we need to set up the web access to P.

cd /etc/apache2

create a P site

cd sites-available/

cp default phabricator

write P as

<VirtualHost *:80>

ServerAdmin webmaster@localhost

ServerName MY-PC-ADDRESS-ON-THE-NETWORK

DocumentRoot /usr/local/phabricator/phabricator/webroot

RewriteEngine on

RewriteRule ^/rsrc/(.*) – [L,QSA]

RewriteRule ^/favicon.ico – [L,QSA]

RewriteRule ^(.*)$ /index.php?__path__=$1 [B,L,QSA]

<Directory “/usr/local/phabricator/phabricator/webroot”>

Install OS for Netbook Acer D250/KAV60

The original thinking is to reuse my netbook which was shipped with windows 7.
The netbook was too slow by running heavily-loaded windows components.

Here is just a quick note of trying various OS.

Chromium OS from Hexxeh distribution was problematic, though installing via USB was easy.
It is no way to detect available wireless connections. I even have tried hotspot from my handphone without any security or open SSID.

Puppy Linux was not going smooth either, because I found the distribution was less maintained, and they are not using hyper image. I have no way to use windows Image Writer to write my USB.

Linux Mint 15 is nice. A lot of documentations are available. Now I am trying to install to hard disk from USB.
I was blackout in the middle, and I thought it was finished. After pulling out the USB, kernel panic!
So I have to do that again. However, after seeing the partition table again, I am wondering if the free space is not enough.
My previous NTFS took all the space of 160G.

By right, I should use window’s disk manager to shrink the giant NTFS under C:\, but the reality turned out that windows won’t give me options to free up all the space I need.

Therefore, bored enough with windows, I decided to give up dual boot and make my netbook solely to linux mint.

I partitioned the entire disk into three. One 20G for root, one 2G for Swap, and the rest for /home.

The results turned as sweet and charm. After half an hour installation, the machine was successfully armed with linux mint 15 with MATE (VLC supported of course).

After that, I installed the driver (for my wireless card), updated software by update manager, installed chromrium browser.

and now I am typing using it.

By default, the mic doesn’t work for Skype.
I followed this guide, and it worked as a charm.
