9-06-2015 Get Kivy to make an android app on my phone using Dalvik (status: done)

Unfortunately my phone won't upgrade to 5.0 so I can use ART. I think once I fix my phone i will switch to ART. The reason is that I am probably a year away from really using it in prod, and a year from now most everything will have ART. I don't care about apple products for cost reasons and target audience.

The nice thing is I might be able to write a program that runs on a phone, tablet, Linux, Windoze, and iOS. It is not going to be an intensive program.

Packaging for android

cd buildozer
sudo python2.7 setup.py install


buildozer init
buildozer android debug deploy run

Had to do some work on apache and git on my local box when pushing to production.
Locally:

• cd /var/www/html/
• rm index.html
• mkdir DIR
• chown work DIR
• In the apache config: /etc/apache2/sites-enabled/000-default.conf
• <Directory "/var/www/html/hhcf/">
  

  AddHandler cgi-script .cgi .py
  AllowOverride All
  Options +Indexes +FollowSymLinks +ExecCGI
  Order allow,deny
  Allow from all
  </Directory>

• a2enmod cgi a2enmod status a2enmod info
• Restart apache

For git I created a bash script to save stuff quickly. I don't care about comments because its all me. I just called it "G" with chmod 755 /usr/local/bin/G.

#!/bin/sh

echo $1

git add $1 

git commit -m "auto"

git push origin master

9-02-2015 VoltDB community install on laptops (status : stuck)

I am going to install the community version of VoltDB. This means you have to compile it.Hope this changes. I will try to get the enterprise edition somehow.

git clone https://github.com/VoltDB/voltdb.git

cd voltdb

On server mark4:

• voltdb create # as the user mark 
• I don't know if its because its a community edition or what, but it spit out some messages.

  Build: 5.6 voltdb-5.5-158-gdb3a5fd Community Edition
  Connecting to VoltDB cluster as the leader...
  Host id of this node is: 0
  Initializing the database. This may take a moment...
  WARN: Strict java memory checking is enabled, don't do release builds or performance runs with this enabled. Invoke "ant clean" and "ant -Djmemcheck=NO_MEMCHECK" to disable.

• Now I need some sort of license, so I am stuck because I want to setup a cluster. Do I need a community license?
