Connecting securely to your home network has always been a bit of a challenge since common home ADSL routers not normally contain any VPN Servers (those which do contain such are generally PPTP servers which I would hardly call secure these days). Which is probably a good thing as they would be horribly out of date considering the firmware release policies of retail router manufacturers. You could run/maintain your own dedicated server, but for most home networks that is overkill and out of the technical depth of most hobbyists. However NAS Appliances are becoming more useful in home networks for storage and other common tasks. I have had good experiences with Synology NAS devices over a number of years and the latest iteration also has a very useful VPN Server package available based on OpenVPN (as most Synology Apps are common Open Source components).

Excellent coincidence that the release of Ubuntu 14.04 LTS (Trusty Tahr) fell into the Easter holidays. This gives me the time to install earlier than I normally have time for.

This realease being a LTS (long-term support) release means it is a fairly conservative release. There are some nice enhancements and most importantly for me the 3.13 Kernel means finally Wacom Touch devices are supported without kernel mods.

Unfortunately the mess that is UEFI Secure Boot still causes issues on some hardware. In my case it’s a Toshiba Z930 Ultrabook. I have documented the procedure to get it working here.

However it turns out that there is no ‘Trusty’ release for the boot-repair utility. The fix is relatively easy.

sudo vim /etc/apt/sources.list.d/yannubuntu-boot-repair-trusty.list
#change the following line from 'trusty' to 'saucy'
sudo vim /etc/apt/sources.list.d/yannubuntu-boot-repair-trusty.list

You can then just finish with

Apache Cordova has very nice documentation, however as so many projects it is focused on the Windows/MacOS duopolies only. Fortunately it’s not too hard to work out the differences.

Installing dependencies

Thanks to: https://github.com/joyent/node/wiki/Installing-Node.js-via-package-manager

sudo apt-get install python-software-properties python g++ make ant openjdk-7-jre openjdk-7-jdk

Installing Android SDK

Please note: one of the problems I found was that I had some Android tools from the Ubuntu repos that were conflicting with the SDK install. It’s probably a good idea to remove them first. That might save you from a lot of headaches down the line (and time to troubleshoot).

Finally found some time playing with a RaspberryPi and an attached PiFace Interface board to control some garden pumps and potentially an Aquaponics setup in the near future.

Requirements

• Raspberry Pi (Model B in my case, but any will do)
• PiFace Interface board (http://www.piface.org.uk)

Base Raspian (Debian Wheezy) Install (I prefer the clean minimal install via https://githutb.com/hifi/raspbian-ua-netins).

Configure the base system as per my previous base install.

As with most hardware manufacturers of hardware Foscam utility software is Windows or Mac only. The actual unit tested with the below is a FI9805E Outdoor POE camera.

Installation

The installation is relatively painless as the unit is set up to get the IP assignment via DHCP (check your routers DHCP assignment list).

should get you to the web-admin interface. The default user is ‘admin’ with no (empty) password.

I have switched most of my Social Media postings to Google+ over the last year. Despite popular opinion being that Google+ is some ‘ghost town’, I find G+ the most useful environment for my particular needs & interests (specially since the introduction of groups). It has in my experience a vastly better signal-to-noise than other social media in particular Facebook.

However I would still like to feed postings through to my Twitter stream. Unfortunately Google has (stupidly / purposely / nastily) not included RSS support to make this possible without much work. There are a few publicly accessibly services out there, but they generally are either not updated or tend to fail very frequently as they hit the API Access limits as soon as they get a few users on their services.

Whilst most commandline editors have the ability to edit files on a remote host directly this can get messy sometimes when there are multiple files involved. Mounting the remote folder via SSHFS seems to be more reliable in practical use.

Mount

sudo apt-get install sshfs
sudo addgroup USERNAME fuse
sshfs remoteuser@remotehost:/remote/path /local/mountpath

Unmount

fusermount -u /local/mountpath

This is the last of a series of alternative mobile OS installs and the easiest install by a country mile !

Install

Everything is quite well documented here: https://wiki.ubuntu.com/Touch/Install.

sudo add-apt-repository ppa:phablet-team/tools
sudo apt-get update
sudo apt-get install phablet-tools android-tools-adb android-tools-fastboot
phablet-flash ubuntu-system --channel devel --bootstrap

That is it really ! This is how a OS change on a mobile should work !

Issues

Ubuntu touch can not yet handle the radio firmware past Android 4.3 devices. So if your N4 was upgraded to Android 4.4 (KitKat) you need to flash the radio to the Android 4.3 (up to Version 2.0.1700.84) else WIFI will not work.

In my never ending quest to find the ideal text editor here is another installment. Since I have been using VIM as my default command line editor for years I thought I give it a try for basic GUI editing as well.

Install and set desktop app & icon

sudo apt-get install
vim vim-gnome
sudo wget --output-document=/usr/share/applications/gvim.desktop https://raw.github.com/leogaggl/misc-scripts/master/gvim.desktop
sudo wget --output-document=/usr/share/icons/hicolor/scalable/apps/gvim.svg http://gfxmonk.net/images/vim-logo/vim-logo.svg
sudo update-desktop-database

Set MIME defaults

vim ~/.local/share/applications/mimeapps.list
#add or edit the following mime type and add others as needed
text/plain=gvim.desktop;

I just had one of my old hand-me-down phones returned by my offspring in a great condition (junior is very careful with his equipment – well done young man !). This doesn’t happen all too often shows that the Nexus S is a decently built phone. This is also a good example of breaking the built-in obsolescence of modern phones. This particular unit has served me well for nearly 2 years (my average is one year) and served 2 kids after that.

I am currently looking into the use of Django for one of my extra-curricular projects and needed to set up a development environment on Ubuntu. This is the log for future reference and hopefully useful for anybody needing to do the same.

Dependencies & Django Installation

Core Dependencies & Django

sudo apt-get install apache2 apache2-mpm-itk libapache2-mod-wsgi mysql-server python-django python-mysqldb

Optional add-ons

For my purposes I need a few more additional modules
