Storing Raspberry PI timelapse images using Linode Object Storage

"possum cam testing" (CC BY-NC-SA 2.0) by leogaggl One common task for my Raspberry Pi Zero with (infrared) Camera is to do still image capture in regular intervals and upload the images for storage and post-processing. A simple way to achieve this with standard software tools available in the Raspberry Pi OS repositories is to use the S3 CLI tools and a simple bash script run by a scheduled cron job.

Accessing Amazon RDS from Desktop

Every once in a while it is handy to be able to access an Amazon RDS Database Instance remotely from a desktop. ssh -i YOUR-AMAZON-PRIVATE-KEY.pem -l YOUR-AMAZON-RDS-USERNAME -L 33060:YOUR-AMAZON-RDS-PRIVATE-IPADDRESS:3306 -N ec2-usr@YOUR-AMAZON-EC2-INSTANCE-PUBLIC-ADDRESS Note: YOURAMAZONRDSPRIVATEIPADDRESS needs to be the AWS internal RDS IP Address – not the external hostname You can then connect to RDS using mysql commands or any GUI tool such as MySQL Workbench via localhost:33060 Thanks to: Dirk Taggesell via AWS Forums

Moving to KVM virtual machines

Installing VirtualBox is getting increasingly painful on Ubuntu due to the problems with UEFI Secure Boot and the VirtualBox kernel modules. Another reason for an alternative is that running VirtualBox VM’s completely in the background is not as straightforward as it could be. From the available alternatives I looked into (VMWare, Xen & KVM) it was KVM that fitted my needs (casual VM usage with mostly headless VM’s for testing purposes).

Good bye Android ? Hello Ubuntu ! Not yet unfortunately ...

It took a while to ship and then also had to make it’s way down under as Meizu only ship to Europe (and Asia I believe).

Accessing your cloud desktop from Chromebook

One of the main reasons for setting up a cloud desktop is that I tend to use a lot of different devices some of which are not very powerful. One of my favorite devices of late has been a HP 11 Chromebook.

ARD Mediathek offline viewing on Ubuntu

Since I am a bit of a sucker for German “Krimis” as well as some their excellent documentaries I like to watch ARD Mediathek IPTV. However there are several problems with this when you live at the opposite side of the world. ARD has a block for any films that are 15+ years outside of 20.00h-6.00h GMT+1. Which makes it pretty much impossible to watch at a reasonable time in Australia.

Upgrading Nokia X to CyanogenMod 11 (via Ubuntu)

LXQt - extending the life of my trusty old EEE PC (even further)

My old Asus EEE PC 900 is the oldest piece of hardware I own. With an old Intel Atom processor and 1GB of RAM it’s never was the fastest kid on the block (in fact I never considered the Windows XP version of the same unit usable as it was very sluggish). However after owning it for nearly 7 years I am very surprised I can still use it. Granted I only use it occasionally when I am at home, but thanks to LXDE it was still usable.

Ubuntu 14.04 - post-install enhancements for Trusty Tahr

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 some things are still not included (such as the boot-repair tools not being part of the standard repos).

Installing Ubuntu on Toshiba Z930 Ultrabook

Since I have been really happy with the performance and mobility on the Toshiba Ultrabooks (see previous blog entries) I have now chosen to stay with a tried brand and uprgrade to the Z930 i7 model. Unfortunately this now comes with added hurdles by our good friends at Microsoft in the form of UEFI and the pre-installed disaster that is Windows 8. Instead of totally wiping the system as I did with the Z830 model I decided to install next to Windows 8 as lots of people have reported problems with the UEFI bootloader and the BIOS if you start messing with the pre-installed partitions (specially the EFI partition).

OpenVPN - forward all client traffic through tunnel using UFW

By default OpenVPN only routes traffic to and from the OpenVPN Server. If you need all traffic from a client through the OpenVPN tunnel there are several options listed in the OpenVPN docs (http://openvpn.net/index.php/open-source/documentation/howto.html#redirect). Since I don’t have any control over the server in some cases I needed a client side solution. As I already have ufw running with Ubuntu I wanted to use the existing software.

Disable services on boot - Ubuntu 12.04

To keep my desktop (notebook) machine light and responsive I don’t want unnecessary services starting on boot-time. Turns out Ubuntu is surprisingly cumbersome to configure in this area (compared to RedHat / Fedora). Two services I need on my notebook, but don’t want them to start unless I require them running are MySQL and Apache. But it looks like some services are started using upstart init daemon and it appears there is no management tool for this.

Galaxy Nexus Firmware Upgrade on Ubuntu (manual)

As a Galaxy Nexus Owner I have been waiting for months for an OTA (over the air) upgrade to the factory installed Firmware (4.0.2). I am finally sick of waiting and complaining to Google (an absolute lost cause). After some research it turns out that (contrary to popular opinion) not every unlocked Google Nexus actually has the ‘official’ Google Firmware. Some of them have a Samsung variant (WTF !?) of the firmware.

Installing Java6 JDK on Ubuntu 12.04

UPDATE: [01-May-2012] It appears that this PPA repo is currently broken (does not allow to get GPG key and has unmet dependencies on x84_64). It appears that the install on i386 systems does work anyway if you ignore the GPG key error, but I wouldn’t install in that case as PPA installs are security risk enough without GPG errors. UPDATE: [11-May-2012] The reason the PPA does not work is that it has been disabled by Ubuntu due to a licensing issue with (not hard to guess) Oracle.

Bulk converting Office documents to PDF

When you need to convert multiple documents to PDF for distribution (or from one Office format to another) there are a few utilities around. The most workable I found is the UNOCONV utility which is build on top of LibreOffice / OpenOffice. This uses the OpenOffice conversion facilities rather than a simple PDF print driver. On Ubuntu it can be installed via Software Center or via apt-get from the core repositories.

Jitsi Ubuntu VoIP SIP Client

Ubuntu - create manual application launcher (Unity)

With every new release of Ubuntu I am becoming more resigned to the fact that the effort to revert back to the Ubuntu Classic (Gnome 2) interface is getting harder and sooner or later I will have to bite the bullet and learn to live with the ugly and more cumbersome Unity interface (specially since Gnome 3 seems to be even worse).

Creating Twitter Archives

One of the more common uses of Twitter for me is to monitor “back-channels” at events (often events I can attend, but more often these days events I am unable to attend). Unfortunately Twitter’s search capabilities cease to be useful after a little while and so it is very handy to be able to create an archive for the events ‘hashtag’. There used to be a number of tools in the early days, but mainly because of Twitter’s changes to policies and very unfortunate morphing into a closed ‘media-publishing’ platform, the developers of such tools were forced to discontinue their services.

I have been a user of an EEE PC 900 for over 10 months now and in general very happy with the form-factor and it’s portability. I has been very useful in public transport, waiting rooms, coffee shops,… However – in terms of Operating Systems I am now on my 3rd OS (despite initially telling myself that I will stick with the default and avoid tinkering) and it looks like I still have not found what I am looking for.

Moving to KVM virtual machines

Installing VirtualBox is getting increasingly painful on Ubuntu due to the problems with UEFI Secure Boot and the VirtualBox kernel modules. Another reason for an alternative is that running VirtualBox VM’s completely in the background is not as straightforward as it could be. From the available alternatives I looked into (VMWare, Xen & KVM) it was KVM that fitted my needs (casual VM usage with mostly headless VM’s for testing purposes).

Enabling the watchdog timer on the Raspberry Pi

However, this would not the preferred method of restarting the unit and in extreme cases this can result in file-system damage that could prevent the RPi from booting. If this occurs regularly you better find the root cause of the problem rather than fight the symptoms.

Bulk converting Office documents to PDF

When you need to convert multiple documents to PDF for distribution (or from one Office format to another) there are a few utilities around. The most workable I found is the UNOCONV utility which is build on top of LibreOffice / OpenOffice. This uses the OpenOffice conversion facilities rather than a simple PDF print driver. On Ubuntu it can be installed via Software Center or via apt-get from the core repositories.

This is a follow-up on an older blog using Ubuntu. Raspberry Pi Prerequisites Since this will be a purely headless install designed to sit in a corner behind the scanner I am using a Base Raspian (Debian Wheezy) install (I personally like the clean minimal install via https://github.com/debian-pi/raspbian-ua-netinst the best). apt-get install sudo vim wget wput libusb-dev build-essential git-core Add non-privileged user account(s) adduser USERNAME adduser USERNAME sudo groupadd scanner usermod -a -G scanner USERNAME

RaspberryPi real-world control with REST API

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. Install Apache & PHP sudo apt-get install apache2 php5 php5-dev php5-cli php5-mcrypt curl raspi-config

FreedomBox + RaspberryPi = FreedomPi

I have been watching progress on FreedomBox ever since watching a video of Eben Moglen a few years ago. Turns out that that they recently announced the availability of their 0.1 preview release.

Enabling the watchdog timer on the Raspberry Pi

Turns out that the Broadcom BCM2708 chip on the RPi has a hardware watchdog. This can be very useful if your RPi is located remotely and locks up. However, this would not the preferred method of restarting the unit and in extreme cases this can result in file-system damage that could prevent the RPi from booting.

Webserver and database combination on Raspberry Pi

My normal combination on the big-server side would be Apache + MySQL (or PostgreSQL), but on the RPi this seems to be absolute overkill. For data-logging operations I would not use the local system anyway (looking at MQTT as well as Remote MongoDB datastore via REST Webservices). After some poking around and reading up on the options I decided to go for the following combo: LightHTTPD + SQLite. Both are lightweight replacement of their fully-featured big-server counterparts (Apache HTTP & MySQL) and have very familiar configurations.

BESPIN - another nice one from Mozilla.org

Getting excited about a new text editor of all things is not something I like to admit to easily, but in my line of work (although less and less is actually doing hands on coding) text editing is an important part. That’s why I checked out the BESPIN project as soon as I heard of it. The prospect of being able to edit your files from anywhere is very appealing to me since I spend a lot of time away from the desk and on devices that not always have good text editor (let alone all the files necessary).

Good bye Android ? Hello Ubuntu ! Not yet unfortunately ...

It took a while to ship and then also had to make it’s way down under as Meizu only ship to Europe (and Asia I believe).

Finding a private location check-in service

Foursquare decided that it was too hard for them to compete with location services like Yelp and split their app into two separate apps.

Being out and about a lot, I am a fairly heavy user of my mobile internet plan (currently with Hutchinson 3). One of the more common tasks when there is some down-time while in transit or waiting for coffee is checking out what’s happening in the twittershere. Personally (being a web-app developer for years) I generally prefer browser-based apps over ‘native apps’. Dont even get me started about J2ME apps. One of the main reasons for this preference is that I tend to switch handsets fairly frequently.

QR code usage in Japan

Just came across this post about barcode tombstones in Japan. Shows very clearly how much public acceptance the 2D barcode technology has got in Japan. It allows visitors to the grave to access to the biography and photos of the deceased person and leave a personal message. This concept probably takes some time to get used to, but you can see that it could clearly add some value for people visiting cemeteries.

iPhone User Survey

As people that know me are aware I am not the biggest fan of the iPhone (3G – hello ???), but obviously from a professional perspective it is another phone that is with us and gaining market share (although not much happening in OZ yet). And to be fair it is breaking some technical ground as well (just not in the areas I most need). From my own anecdotal evidence I was expecting a high percentage of users to choose the iPhone because it ‘looks cool’ or is a ‘chick magnet’ – but I can not back this up by an empirical research (yet) ;-).

Unmetered mobile access to university websites

I came accross this article last week which I found quite interesting in terms of it’s impact on m-Learning. University inks unmetered Web access deal with Bigpond The unfortunate thing is that this is only limited to one particular university and one provider only. It would be interesting to see if there are any other institutions that are going down that track. How about a general unmetering for the ‘edu.au’ TLD ?

Mobile 2D codes gathering pace (outside of Asia)

FINALLY !!! As somebody that has been experimenting with this technology for over 2 years now I am quite exited to see that the adoption of this technology is gathering some steem. While it has bee widely adopted in Asia for some years now, it has taken some time to get a foothold in the rest of the world this seems to be changing now. At least in Europe as I can see for myself at the moment.

Using Nokia Mobile Webserver in an educational environment.

The ability to host your own content from your mobile phone opens some interesting possibilities to engage students and will allow the integration of user generated content in the education process. David Johnson from the University of Reading is working on serving portfolio data from your mobile. Some of the current limitation of this approach: -cost of the bandwidth -speed The ability to proxy the users content on the Mobile Web server Gateway as well as the ability to integrate content outside of the mobile phone seem to be the main points that will have to be improved for this to become a more mainstream technology.

Zero dollar minimum spend post-paid phone plans in Australia

Good bye Android ? Hello Ubuntu ! Not yet unfortunately ...

As a long-term Ubuntu user I am extremely interested in what Canonical and the Ubuntu community are doing on the mobile front. Their convergence strategy (I am testing Snappy Core on IoT devices as well) seems very well thought through and once the the Meizu MX4 phone was released I got myself an invite and ordered a unit. It took a while to ship and then also had to make it’s way down under as Meizu only ship to Europe (and Asia I believe).

Finding Notebook Hardware for Ubuntu - 2015 Edition

Synology OpenVPN connection from Android

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.

Installing Ubuntu on Toshiba Z930 Ultrabook

Since I have been really happy with the performance and mobility on the Toshiba Ultrabooks (see previous blog entries) I have now chosen to stay with a tried brand and uprgrade to the Z930 i7 model. Unfortunately this now comes with added hurdles by our good friends at Microsoft in the form of UEFI and the pre-installed disaster that is Windows 8. Instead of totally wiping the system as I did with the Z830 model I decided to install next to Windows 8 as lots of people have reported problems with the UEFI bootloader and the BIOS if you start messing with the pre-installed partitions (specially the EFI partition).

Ubuntu 14.04 - post-install enhancements for Trusty Tahr

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.

ARD Mediathek offline viewing on Ubuntu

Since I am a bit of a sucker for German “Krimis” as well as some their excellent documentaries I like to watch ARD Mediathek IPTV. However there are several problems with this when you live at the opposite side of the world. ARD has a block for any films that are 15+ years outside of 20.00h-6.00h GMT+1. Which makes it pretty much impossible to watch at a reasonable time in Australia.

Re-index media files on Synology NAS servers

One of the annoying things with Synology NAS servers is the fact that a video file moved to the filesystem does not automatically appear on the DNLA share on client devices. It needs a re-index of the media files. You can log into the HTML Admin Console and start a re-index, however this will be a full re-index and most likely take ages to complete. A quicker way is to connect to the SSH Console and issue the following command:

Upgrading Nokia X to CyanogenMod 11 (via Ubuntu)

Nothing spectacular in terms of computing power, but much better build quality than your average cheap Chinese Android clone.

David Johnson from the University of Reading is working on serving portfolio data from your mobile. Some of the current limitation of this approach: -cost of the bandwidth -speed The ability to proxy the users content on the Mobile Web server Gateway as well as the ability to integrate content outside of the mobile phone seem to be the main points that will have to be improved for this to become a more mainstream technology.

LXQt - extending the life of my trusty old EEE PC (even further)

My old Asus EEE PC 900 is the oldest piece of hardware I own.

The install is easy as it’s part of the Ubuntu Community Software (Universe) and that means it can be installed via apt-get, Software Center or Synaptic. So far the early testing has been very positive and the interface seems quite workable as well as having a number of other instant messaging options available.

Synology OpenVPN connection from Android

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.

OpenVPN - forward all client traffic through tunnel using UFW

By default OpenVPN only routes traffic to and from the OpenVPN Server. If you need all traffic from a client through the OpenVPN tunnel there are several options listed in the OpenVPN docs (http://openvpn.net/index.php/open-source/documentation/howto.html#redirect). Since I don’t have any control over the server in some cases I needed a client side solution. As I already have ufw running with Ubuntu I wanted to use the existing software. Here is how to configure ufw to enable routing all traffic from your client machines through the OpenVPN Server.

Also Ethernet bridging is not available (at least on the service I used) so you’re stuck with NAT IP masquerading.

Since some older hardware (Toshiba Satellite A300 for example) has issues with the current version of Grub as well as the newer Kernel I still need to run 10.04 on some machines. However since the 10.04 Repository still uses Firefox 3.6 you need to add a PPA repo to upgrade to Firefox 4. Either go to Ubuntu Software Center > Software Sources and click the ‘Other Software’ tab. Press ‘Add’ and enter ppa:mozillateam/firefox-stable

Install FirefoxOS on Nexus S (GT-9023)

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.

Ubuntu Apache2 - run VHOST as different user

There are several reasons why you might want to run different Apache Virtual Hosts as separate users from the Apache user account. My most frequent usage is on my development machine to allow running from my home directory. The most commonly recommended option for this purpose is MPM-ITK (a quick hack would be to add yourself to the www-data group using “sudo usermod -a -G www-data USERNAME”) sudo apt-get install apache2-mpm-itk sudo a2enmod mpm_itk

Re-index media files on Synology NAS servers

One of the annoying things with Synology NAS servers is the fact that a video file moved to the filesystem does not automatically appear on the DNLA share on client devices. It needs a re-index of the media files. You can log into the HTML Admin Console and start a re-index, however this will be a full re-index and most likely take ages to complete. A quicker way is to connect to the SSH Console and issue the following command:

Bulk converting Office documents to PDF

When you need to convert multiple documents to PDF for distribution (or from one Office format to another) there are a few utilities around. The most workable I found is the UNOCONV utility which is build on top of LibreOffice / OpenOffice. This uses the OpenOffice conversion facilities rather than a simple PDF print driver. On Ubuntu it can be installed via Software Center or via apt-get from the core repositories.

Installing Ubuntu on Toshiba Z930 Ultrabook

Since I have been really happy with the performance and mobility on the Toshiba Ultrabooks (see previous blog entries) I have now chosen to stay with a tried brand and uprgrade to the Z930 i7 model. Unfortunately this now comes with added hurdles by our good friends at Microsoft in the form of UEFI and the pre-installed disaster that is Windows 8. Instead of totally wiping the system as I did with the Z830 model I decided to install next to Windows 8 as lots of people have reported problems with the UEFI bootloader and the BIOS if you start messing with the pre-installed partitions (specially the EFI partition).

OpenVPN - forward all client traffic through tunnel using UFW

By default OpenVPN only routes traffic to and from the OpenVPN Server. If you need all traffic from a client through the OpenVPN tunnel there are several options listed in the OpenVPN docs (http://openvpn.net/index.php/open-source/documentation/howto.html#redirect). Since I don’t have any control over the server in some cases I needed a client side solution. As I already have ufw running with Ubuntu I wanted to use the existing software. Here is how to configure ufw to enable routing all traffic from your client machines through the OpenVPN Server.

OpenVPN Install on CentOS 6 Server

I recently had a need to install a VPN service in a OpenVZ container. Since I normally only use Hardware emulating VM’s I ran into quite a few issues in terms of low-level networking support on this Container Virtualisation System. Turns out that you are stuck with a TUN/TAP solution as most services won’t enable PPP services on their infrastructure. Also Ethernet bridging is not available (at least on the service I used) so you’re stuck with NAT IP masquerading.

Enabling the watchdog timer on the Raspberry Pi

Turns out that the Broadcom BCM2708 chip on the RPi has a hardware watchdog. This can be very useful if your RPi is located remotely and locks up. However, this would not the preferred method of restarting the unit and in extreme cases this can result in file-system damage that could prevent the RPi from booting. If this occurs regularly you better find the root cause of the problem rather than fight the symptoms.

After a fair bit of searching it turns out that you only need to install one additional package (usb-modeswitch) to make this modem work (be recognised) on the current stable 10.

Creating Twitter Archives

One of the more common uses of Twitter for me is to monitor “back-channels” at events (often events I can attend, but more often these days events I am unable to attend). Unfortunately Twitter’s search capabilities cease to be useful after a little while and so it is very handy to be able to create an archive for the events ‘hashtag’. There used to be a number of tools in the early days, but mainly because of Twitter’s changes to policies and very unfortunate morphing into a closed ‘media-publishing’ platform, the developers of such tools were forced to discontinue their services.

Organisational micro-blogging for all

Micro-blogging is like Twitter, but private to your organisation. It is a great way to capture those more informal internal discussions.

Need for digital (media) literacy

I just recently stumbled across this link to the ‘Heartland Institute‘ via a reference in an American Newspaper site citing their sources for an article about the US Economic Stimulus package. I initially was hoping this might be a satiric site such as CNNN, but after taking a closer look and checking out some references it appears these people are actually serious (and worse still seem to have a lot of funds at their disposal to spread their dubious view).

BESPIN - another nice one from Mozilla.org

Getting excited about a new text editor of all things is not something I like to admit to easily, but in my line of work (although less and less is actually doing hands on coding) text editing is an important part. That’s why I checked out the BESPIN project as soon as I heard of it. The prospect of being able to edit your files from anywhere is very appealing to me since I spend a lot of time away from the desk and on devices that not always have good text editor (let alone all the files necessary).

Galaxy Nexus Firmware Upgrade on Ubuntu (manual)

I am finally sick of waiting and complaining to Google (an absolute lost cause).

Some of them have a Samsung variant (WTF !?) of the firmware.

VoIP client for Ubuntu II

After upgrading to Ubuntu 11 (Natty) I did some further research on VoIP clients (SIP) for Ubuntu Linux as XLite seems horribly out of date now. I came across QuteCom (formerly WengoPhone) and from first testing it seems to work quite well. The install is easy as it’s part of the Ubuntu Community Software (Universe) and that means it can be installed via apt-get, Software Center or Synaptic. So far the early testing has been very positive and the interface seems quite workable as well as having a number of other instant messaging options available.

Installing Java6 JDK on Ubuntu 11.10

UPDATE: To install on 12.04 (Precise Pangolin) you need a different PPA. Since sun-java6-jdk has been removed from the default Ubuntu 11.10 (Oneiric Ocelot) repositories you need to add a PPA repository (unless you want to install by hand) sudo add-apt-repository ppa:ferramroberto/java sudo apt-get update sudo apt-get install sun-java6-jdk sun-java6-plugin

Installing the latest stable version of LibreCAD on Ubuntu

I have recently been looking at different CAD options on Ubuntu and LibreCAD (http://librecad.org/) is looking like the best option for my needs at current (apart from the wish there would be some DWG support). Since the main Ubuntu repositories are usually a fair bit behind the lastest stable realeases of LibreCAD you need to add the LibreCAD Dev PPA Repository sudo add-apt-repository ppa:librecad-dev/librecad-stable sudo apt-get update sudo apt-get install librecad

Darktable - Photo Management under Ubuntu

Whilst I am by no means a photographer I do end up taking quite a few photos (these days pretty much exclusively on my phone) and the management of these photos can be a pain. So far I have never found an program worth the pain over plain old file management. But having stumbled across Darktable (http://darktable.org/) I think I might have found a worthwile package. Install on Ubuntu: sudo add-apt-repository ppa:pmjdebruijn/darktable-release sudo apt-get update sudo apt-get install darktable

Bulk converting Office documents to PDF

When you need to convert multiple documents to PDF for distribution (or from one Office format to another) there are a few utilities around. The most workable I found is the UNOCONV utility which is build on top of LibreOffice / OpenOffice. This uses the OpenOffice conversion facilities rather than a simple PDF print driver. On Ubuntu it can be installed via Software Center or via apt-get from the core repositories.

Jitsi Ubuntu VoIP SIP Client

The latest instalment in my never-ending quest to find a decent SIP client (see Ubuntu SIP I & Ubuntu SIP II) I came across JITSI (http://jitsi.org/). Since the website looked very interesting and the project seems very well maintained (http://jitsi.org/index.php/Main/Screenshots) I decided to give it a go. The installation is a breeze with a Ubuntu/Debian package available and the installation also adds the repository to keep the package up to date.

VoIP client for Ubuntu II

After upgrading to Ubuntu 11 (Natty) I did some further research on VoIP clients (SIP) for Ubuntu Linux as XLite seems horribly out of date now. I came across QuteCom (formerly WengoPhone) and from first testing it seems to work quite well. The install is easy as it’s part of the Ubuntu Community Software (Universe) and that means it can be installed via apt-get, Software Center or Synaptic. So far the early testing has been very positive and the interface seems quite workable as well as having a number of other instant messaging options available.

VoIP client for Ubuntu

Having used IP Telephony for a number of years I need a workable SIP client for all of the devices I use. I have found a very capable client for my Android phones (SipDroid) and on Windows/MacOSX I generally use X-Lite (as well as it’s paid version EyePhone) from Counterpath. Having tried several different Linux SIP clients (Ekiga, Twinkle, …) but all discarded them because of weird UI’s and/or problems with stability I noticed that there is a Linux version of XLite available.

Android 4.0 screenshot functionality on Galaxy Nexus

One of the features I missed since the good old Android 1.5 days was the ability to take screen-shots on the device. Prior to Android 4 (ICS) the only workable way to create screen-shots was to connect via USB cable and use the Android SDK to make remote screen-shots. On Android 4.0 all you have to do is press Volume Down Key + Power Key down at the same time and hold.

After doing some research into which of the major manufacturers offer the best support for a Linux based Operating System it came down to a final two: the Intel i7 variants of Samsung Series 9 and the Toshiba Z830.

Working with Second Life in an educational sense

With the help of SL resident Moggs Oceanlane I was able to get our first Sloodle implementation off the ground. Being a bit new on the SL concepts (Moodle as such is my daily life) I found the technical process quite easy, but was struggling with SL terminology a little. Looking forward to getting some hands-on experience of the use of SL in an educational setting. I can see the practical applications – looking for some pilot projects to put them into ‘reality’ once we have got all the technical side tested thoroughly.

Using Nokia Mobile Webserver in an educational environment.

The ability to host your own content from your mobile phone opens some interesting possibilities to engage students and will allow the integration of user generated content in the education process. David Johnson from the University of Reading is working on serving portfolio data from your mobile. Some of the current limitation of this approach: -cost of the bandwidth -speed The ability to proxy the users content on the Mobile Web server Gateway as well as the ability to integrate content outside of the mobile phone seem to be the main points that will have to be improved for this to become a more mainstream technology.

m-learn: Mobile evidence gathering using GoogleDocs

This one nearly escaped my attention yesterday. Google has just announced the ability to edit Google Docs on your mobile device via their Google Mobile Blog. Just point your mobile browser to m.google.com/docs and start editing. Along with the use of 2D barcodes this will open a few interesting m-learning possiblities for educators that would previously have required custom coding to achieve. I can see this being very useful in situations where you have students being in the field and allowing them to enter data gathered using a standard mobile phone.

Open Governance Index – measuring openness

The Open Governance Index measures the true openness of eight open source projects – Android, Qt, Symbian, MeeGo, Mozilla, WebKit, Linux and Eclipse – and analyses how governance, and not licenses, tell the full story of a project’s openness, across transparency, influence and control.

Ubuntu - create manual application launcher (Unity)

With every new release of Ubuntu I am becoming more resigned to the fact that the effort to revert back to the Ubuntu Classic (Gnome 2) interface is getting harder and sooner or later I will have to bite the bullet and learn to live with the ugly and more cumbersome Unity interface (specially since Gnome 3 seems to be even worse). One of the first issues I found is that there seems to be no easy way to manually add programs to the “Launcher” (as well as to the applications list).

Export Delicious Bookmarks in XML

After the recent takeover of Delicious from Yahoo Inc by Avos and the subsequent total screw-up of what was a workable system I have been struggling to export bookmarks from Delicious in XML format (since the API is badly broken). The API export of all bookmarks limits the export to 1000 bookmark entries. Which is fine if you have less than 1000 bookmarks stored. But it makes it impossible (since there is no paging functionality exposed by the API) to export the rest should you have more (and many people would have much more than that).

m-learn: Mobile evidence gathering using GoogleDocs

This one nearly escaped my attention yesterday. Google has just announced the ability to edit Google Docs on your mobile device via their Google Mobile Blog. Just point your mobile browser to m.google.com/docs and start editing. Along with the use of 2D barcodes this will open a few interesting m-learning possiblities for educators that would previously have required custom coding to achieve. I can see this being very useful in situations where you have students being in the field and allowing them to enter data gathered using a standard mobile phone.

OpenSource e-book creation

After recently researching the available software for e-book creation for some of our clients (in the education sector) I came across quite a number of options. However after some further look into the option and trying some I was able narrowed the field down to 2 options that seem to be reasonably user-friendly and matured. The two are using a very different approach and will suit different types of users. One is a native e-book writer which will give better low-level control for the more technical types.

Running your business (mostly) on Open Source Software

The release of the latest Ubuntu Version has been seen by a number of commentators as the most end-user friendly yet and signals another milestone in the readiness of Free and Open Source Software (FOSS) for more widespread (and business) use. As a long-term user of a number of different Operating Systems and as SME Owner for the last 15 years I have overseen the gradual replacement of a number of proprietary software solutions with FOSS Alternatives.

Installing Ubuntu: Extending the HP Touchpad

As one of those who grabbed a HP Touchpad at the recent firesale (after announcing the killing of the product line) I did it as in full knowledge that this device in it’s current form is of limited use and (highly) unlikely to have lots of additional applications created for it. After casually using it for a few nights of use I am personally not surprised that HP decided to ditch this product.

iPad Alternatives

Due to the hype generated by the recent launch and my reservations on using the Apple Inc. iTunes I was doing some research into alternatives to the proprietary and completely locked iPad device (and the associated lock-down to Apple’s iTunes Store). Hopefully this list can be of use for other people as well. I can see the form factor and the tablet style with a cut down (mainly web-browser based) Operating System as useful in a number of settings not least in educational institutions and libraries.

Upgrade to Firefox 4 on Ubuntu 10.04

Since some older hardware (Toshiba Satellite A300 for example) has issues with the current version of Grub as well as the newer Kernel I still need to run 10.04 on some machines. However since the 10.04 Repository still uses Firefox 3.6 you need to add a PPA repo to upgrade to Firefox 4. Either go to Ubuntu Software Center > Software Sources and click the ‘Other Software’ tab. Press ‘Add’ and enter ppa:mozillateam/firefox-stable

VoIP client for Ubuntu II

After upgrading to Ubuntu 11 (Natty) I did some further research on VoIP clients (SIP) for Ubuntu Linux as XLite seems horribly out of date now. I came across QuteCom (formerly WengoPhone) and from first testing it seems to work quite well. The install is easy as it’s part of the Ubuntu Community Software (Universe) and that means it can be installed via apt-get, Software Center or Synaptic. So far the early testing has been very positive and the interface seems quite workable as well as having a number of other instant messaging options available.

GoogleApps (Gmail) as default Ubuntu mail client

Keeping mail on a local machine does not make sense when working across a large number of different (vitual) devices. As a GoogleApps user I have long preferred browser based mail client as my default. Unfortunately this is not yet a very straight process on most Operating Systems and Ubuntu is no difference. Edit: all the commands need to be run with root privileges. so either run “sudo su” or prefix all with “sudo ” (thanks to Paul for the comment below)

Since Ubuntu 9.10 NetbookRemix has been released I am again finding myself using my trusty old ASUS EEE when on the road.

One thing I don’t need on the road (as a matter of fact on none of my equipment) is having to install & maintain some client/server mail client.

EDIT: As of Ubuntu 11.10 (Oneiric Ocelot) this is now much easier as KeePass 2 has finally made it into the repositories apt-get install keepass2 ————————————————————————————————————- If you need to read KeepPass 2 data files (.kdbx) on Ubuntu (as well as from other platforms such as Windows or Android) you need to run the Portable Version under Mono (.NET Runtime). Make sure you download the Portable Version 2.x from http://keepass.info/download.html

Find the direct link to a Twitter status update

I sometimes need to link to a specific Twitter status update and since the recent upgrade (or as I personally see it downgrade) of the Twitter UI it is quite annoying to find the Status ID, as it can not be copied from the interface (without some Javascript debugging tools at least). http://api.twitter.com/1/statuses/user_timeline.xml?screen_name=[screen_name] This will show the users timeline in XML format revealing the Status ID in the XML result. The following URL can be used to then construct the permalink to the specific status update:

My mobile personal learning environment

Taking part in MobiMOOC has given me the opportunity to take stock of my own MobilePLE – the top 5 tools I find most useful as part of my ongoing learning. Catch Notes (previously 3Bananas) – mobile note taking the most critical component. Whenever I get a new device – this is what has to be installed as one of the first actions. For those not familiar with this software – it’s like Evernote without the bloat.

Using Yahoo Pipes to aggregate learning resources

I am using the opportunity of me taking part in a Massive Open Online Course (MOOC) on mobile learning as an excuse to add some more content to this neglected blog. On of the issues I am facing with my participation in the MOOC is the massive amount of e-mails generated and my already overflowing inbox would not cope (let alone me managing it). That is not taking into account other sources such as Twitter & Flickr

Revert Ubuntu Netbook UI

If you upgrade you Ubuntu Netbook release to 10.10 (Maverick Meerkat) you will notice a change to the new ¨Unity¨ user interface. Personally I think the new interface is absolutely horrible (from a usability perspective) and I wanted to revert to the previous Netbook-Launcher. HOWTO Install the required components via terminal: sudo apt-get install netbook-launcher-efl After install just change the “Login Settings” Log out and after the next login: voila – the laucher interface:

VoIP client for Ubuntu

Having used IP Telephony for a number of years I need a workable SIP client for all of the devices I use. I have found a very capable client for my Android phones (SipDroid) and on Windows/MacOSX I generally use X-Lite (as well as it’s paid version EyePhone) from Counterpath. Having tried several different Linux SIP clients (Ekiga, Twinkle, …) but all discarded them because of weird UI’s and/or problems with stability I noticed that there is a Linux version of XLite available.

Huawei K3765 on Ubuntu 10.04 (Lucid)

Since I have switched my 3G data network from Hutchinson Three to Vodafone AU recently I also upgraded the USB modem from a Huwaei E220 (which used to work fine on recent Ubuntu NBR releases on my trusty old ASUS EEE 900) Unfortunately the new Huawei K3765 would not be recognised as a valid modem by the network manager. After a fair bit of searching it turns out that you only need to install one additional package (usb-modeswitch) to make this modem work (be recognised) on the current stable 10.

iPad Alternatives

Due to the hype generated by the recent launch and my reservations on using the Apple Inc. iTunes I was doing some research into alternatives to the proprietary and completely locked iPad device (and the associated lock-down to Apple’s iTunes Store). Hopefully this list can be of use for other people as well. I can see the form factor and the tablet style with a cut down (mainly web-browser based) Operating System as useful in a number of settings not least in educational institutions and libraries.

Ubuntu - Google Mail (GoogleApps) as default mail client

Since Ubuntu 9.10 NetbookRemix has been released I am again finding myself using my trusty old ASUS EEE when on the road. And finally it seems I have found a vanilla Linux distribution that is reasonably responsive and works ‘out of the box’. One thing I don’t need on the road (as a matter of fact on none of my equipment) is having to install & maintain some client/server mail client.

Useful software for practical mobile learning

Since a fair bit of my time is spent working and researching in the field of Mobile Learning and there is not a lot of recent listings of Software useful in practical m-Learning implementations I have compiled the following list from my bookmarks and Software I commonly use for these purposes. This list tries to represent currently usable applications not applications in the development stage. Rather than writing this in the form of a blog entry I decided to keep this as a live document within Google Apps that people can contribute to.

QR code usage in Japan

Just came across this post about barcode tombstones in Japan. Shows very clearly how much public acceptance the 2D barcode technology has got in Japan. It allows visitors to the grave to access to the biography and photos of the deceased person and leave a personal message. This concept probably takes some time to get used to, but you can see that it could clearly add some value for people visiting cemeteries.

Mobile 2D codes gathering pace (outside of Asia)

FINALLY !!! As somebody that has been experimenting with this technology for over 2 years now I am quite exited to see that the adoption of this technology is gathering some steem. While it has bee widely adopted in Asia for some years now, it has taken some time to get a foothold in the rest of the world this seems to be changing now. At least in Europe as I can see for myself at the moment.

Need for digital (media) literacy

I just recently stumbled across this link to the ‘Heartland Institute‘ via a reference in an American Newspaper site citing their sources for an article about the US Economic Stimulus package. I initially was hoping this might be a satiric site such as CNNN, but after taking a closer look and checking out some references it appears these people are actually serious (and worse still seem to have a lot of funds at their disposal to spread their dubious view).

Ubuntu - the ‘old man’ experiment

Recently my father, who has so far not wanted to have anything to do with computers, decided to change all of this with age 67. While initially surprised (and remembering the comments I got when sitting in front of computers as a teenager instead of working on the family farm), I quite liked the idea. It’s a great to see him still wanting to explore and learn new things. Unfortunately since there is approximately 17.

m-learn: Mobile evidence gathering using GoogleDocs

This one nearly escaped my attention yesterday. Google has just announced the ability to edit Google Docs on your mobile device via their Google Mobile Blog. Just point your mobile browser to m.google.com/docs and start editing. Along with the use of 2D barcodes this will open a few interesting m-learning possiblities for educators that would previously have required custom coding to achieve. I can see this being very useful in situations where you have students being in the field and allowing them to enter data gathered using a standard mobile phone.

Working with Second Life in an educational sense

With the help of SL resident Moggs Oceanlane I was able to get our first Sloodle implementation off the ground. Being a bit new on the SL concepts (Moodle as such is my daily life) I found the technical process quite easy, but was struggling with SL terminology a little. Looking forward to getting some hands-on experience of the use of SL in an educational setting. I can see the practical applications – looking for some pilot projects to put them into ‘reality’ once we have got all the technical side tested thoroughly.

Using Nokia Share Online to upload directly to Flickr

One of the nicest ways to get photos straight from your mobile to Flickr (without having to use e-mails) on Nokia devices is the Flickr Plugin for the Nokia Share Online application. Since a lot of my clients in the educational sector are starting to use Flickr as part of their online teaching I decided to create a short HOWTO. The application itself comes with the phone on most recent Nokia S60 devices (with recent Firmware – check Nokia Software Updater for new firmware).

Finding the ideal OS for (my) EEE PC

Testing mobile Twitter clients

Being out and about a lot, I am a fairly heavy user of my mobile internet plan (currently with Hutchinson 3). One of the more common tasks when there is some down-time while in transit or waiting for coffee is checking out what’s happening in the twittershere. Personally (being a web-app developer for years) I generally prefer browser-based apps over ‘native apps’. Dont even get me started about J2ME apps. One of the main reasons for this preference is that I tend to switch handsets fairly frequently.

BESPIN - another nice one from Mozilla.org

Getting excited about a new text editor of all things is not something I like to admit to easily, but in my line of work (although less and less is actually doing hands on coding) text editing is an important part. That’s why I checked out the BESPIN project as soon as I heard of it. The prospect of being able to edit your files from anywhere is very appealing to me since I spend a lot of time away from the desk and on devices that not always have good text editor (let alone all the files necessary).

However due to the fact that our business is growing and we were at the end of a financial year the pain of using MYOB became greater than the pain of switching.

iPhone User Survey

As people that know me are aware I am not the biggest fan of the iPhone (3G – hello ???), but obviously from a professional perspective it is another phone that is with us and gaining market share (although not much happening in OZ yet). And to be fair it is breaking some technical ground as well (just not in the areas I most need). From my own anecdotal evidence I was expecting a high percentage of users to choose the iPhone because it ‘looks cool’ or is a ‘chick magnet’ – but I can not back this up by an empirical research (yet) ;-).

After reading an excellent article by Brad Reed on Network World (this seems to be the online version: Co-working: the ultimate in teleworking flexibility),ï¿½I finally got motivated enough to do some more research about thisï¿½phenomenum in the two places of interest to me (Austria and Australia)ï¿½as well as write a quick entry about this. The whole co-working concept has been interesting me ever since it started, but the organisational issues associated with starting such aï¿½venture (and as with everything else – a lack of time) have alwaysï¿½prevented any serious attempt to actually move in this direction.
