hpr1738 :: Open Systems Interconnection (OSI) model (ISO/IEC 7498-1)

Released on 2015-04-01 under a CC-BY-SA license.
This is another in the series of exploring The Open Systems Interconnection (OSI) model (ISO/IEC 7498-1)

OSI model
From Wikipedia, the free encyclopedia

The Open Systems Interconnection (OSI) model (ISO/IEC 7498-1) is a product of the Open Systems Interconnection effort at the International Organization for Standardization. It is a prescription of characterizing and standardizing the functions of a communications system in terms of abstraction layers. Similar communication functions are grouped into logical layers. A layer serves the layer above it and is served by the layer below it.

For example, a layer that provides error-free communications across a network provides the path needed by applications above it, while it calls the next lower layer to send and receive packets that make up the contents of that path. Two instances at one layer are connected by a horizontal connection on that layer.

hpr1710 :: Windows Remote Desktop on GNU/Linux

Released on 2015-02-20 under a CC-BY-SA license.

Recorded using Easy Voice Recorder Pro

I wrote a bash script to connect to various different windows servers from my GNU/Linux desktops. I had a few different requirements:

  • I should be able to call it based on hostname.
  • All windows should be 90% smaller than my screen.
  • It should map my keyboard.
  • It should map my local disk.
  • It should quickly timeout if the port is not available.

You can get the full script here, but let’s walk through it:

The first line calls bash and then gets the server name from the symlink that is calling the script. The port is set as “3389”, but you can change that if you like.

SERVER=`basename $0`

The next few lines finds the smallest vertical and horizontal sizes, even if you are running multiple screens. Then it calculates 90% of that to use as the size.

h=$(echo "scale=0;(($(xrandr | grep '*+' | sed 's/x/ /g' | awk '{print $1}' | sort -n | head -1 )/100)*90)" | bc)
v=$(echo "scale=0;(($(xrandr | grep '*+' | sed 's/x/ /g' | awk '{print $2}' | sort -n | head -1 )/100)*90)" | bc)

Next we set the default username and password. I have it ask me for my password but I put it in here as an example.


In some cases the credentials may be different, so I have a case statement that will cycle through the servers and apply the differences. Depending on your naming schemes you may be able to use regular expressions here to filter out groups of servers.

case "${SERVER}" in
  *server*) echo "Server ${SERVER}"
  *colo*) echo "Server ${SERVER}"
  some_server ) echo "Server ${SERVER}"
  *) echo "No match for ${SERVER}, using defaults"

Next we use an inbuilt bash command to see if a remote port is open and timeout after one second.

timeout 1 bash -c "echo >/dev/tcp/${SERVER}/${PORT}"

I used to connect to rdp using the program rdesktop, but it is now of limited value due to the fact that there are many open bugs that are not getting fixed. Bugs such as Bug 1075697 - rdesktop cannot connect to systems using RDP version 6 or newer  and Bug 1002978 - Failed to negotiate protocol, retrying with plain RDP . I then switch to using xfreerdp. This is the client that is behind remmina.

You can use xfreerdp /kbd-list to get a list of the available keyboard layouts.

if [ $? -eq 0 ]; then
  echo "${SERVER}:${PORT} is open"
  xfreerdp /v:${SERVER} /size:${SIZE} /kbd-type:0x00000409 /t:${SERVER} /d:${WORKGROUP} /u:${USERNAME} /p:${PASSWORD} /a:drive,pc,/ /cert-ignore &
  echo "${SERVER}:${PORT} is closed"

Next you will need to be sure that your host names are available, either in dns or in your /etc/hosts/ file. For example: server1 server2 server3 coloserver1 coloserver2 coloserver3 some_server

Edit the script to your liking and then put it into your a directory in your path, possibly /usr/local/bash or ~/bin/. You can then make symbolic links to the servers to the bash script, also in a directory in your path, using the command:

ln -s /usr/local/bash/rdp.bash ~/bin/some_server
chmod +x ~/bin/some_server

Which links the global rdp.bash script to your personal symlink, and makes it executable.

All that you need to do then is type the name of the server and a rdp screen should pop up.

In our example:

$ some_server

From there your Windows Server session should pop up.

hpr1654 :: Using AS numbers to identify where you are on the Internet

Released on 2014-12-04 under a CC-BY-SA license.

I have a laptop and I want it to use different configurations depending on where I am. If I’m on wifi at home, I don’t want my NAS mounted, but if I’m on a wired connection I do. If I’m at work I want to connect to various servers there. If I’m in the train I want to setup a vpn tunnel. You get the idea.

My solution to this was to approach it from the laptop and go out. So to look around and see what network I was on. There are a few ways to approach this, you could look at your IP address, the arp tables, try and ping a known server in each location. The issue with looking at an IP address is that most networks use Private Networks. Very soon you will find that the wifi coffee shop happens to have picked the same range as you use at home and now your laptop is trying to backup to their cash register.

Then I was thinking that I’m approaching this problem from the wrong angle. Why not start with my public IP address range, which has to be unique, and work back from there to my laptop. From there I was planning on maintaining a look-up table of public IP addresses, along the lines of the GeoIP tools developed by MaxMind.

By Accident I found out that geoiplookup supports AS Number

From WikiPedia: Autonomous System (Internet)
ISP must have an officially registered autonomous system number (ASN). A unique ASN is allocated to each AS for use in BGP routing. AS numbers are important because the ASN uniquely identifies each network on the Internet.

So what that is saying is that every network in the Inter(connected)Net(work), must have it’s own unique AS Number. From there I was able to write a script to easily manage my laptops behaviour based on both location and connection type

hpr1480 :: Continuous Ink Supply System

Released on 2014-04-04 under a CC-BY-SA license.

The cost of printing

The reason that printers are so affordable is because like game consoles, they are not. They are sold at cost or below cost. The printer manufacturers make their money by selling you replacement ink cartridges that are very expensive. While you can use replacement cartridges, the manufactures will try and dissuade you from using them by displaying messages in the screens to "alert" you to the fact, or will include chips in their printers to prevent you from refilling or swapping their cartridges for cheaper alternatives. You should consider a laser printer option as while the toner cartridges are more expensive, even those supplied by the manufacturers work out cheaper over time. But if you wish to use a Ink Jet, then a serious alternative to lower the cost of printing is to use a CISS, Continuous ink supply system.

CISS, Continuous ink supply system

A CISS, Continuous ink supply system, is a system where you use cheaper non brand ink in your printer, just like you would with replacement no-name brand cartridges. Instead of having to refill the cartridges as they empty you supply them via a thin hose to an external reservoir. The advantage is that you can buy your ink in bulk and refill it without having to open the printer. This brings the cost of printing considerably.
link to picture of CISS printer

Now to pick a printer

  1. What Functions would you like ?
    In the Netherlands there is an excellent site called that allow you to select devices by their features without having to gather all the information from various review sites that may/may not be influenced by outside forces. Although the site is in Dutch it should be fairly obvious what's been asked. (Google Translate version)
  2. Will it work with Linux
    Once you short list the printer(s) you like, head over to to find out if it's supported by Linux and by extension Mac/iOS. Do this even if you plan to run Windows as it proves that the printer is popular and is likely to be supported.
  3. Will it really work with Linux
    Support is a big word and while it may be trivial for some to recompile a Kernel and X to get the thing working. It saves a lot of time and effort if you look around on the Linux Distributions forums to see if there are reported problems installing the printer. A good search is "${your printer model number} linux howto", check the dates on the posts as well paying more attention to the newer ones. Don't worry if you find a HowTo on another distribution than the one you are using as the chances are good that it will also apply to your install.
  4. Can you easily use replacement cartridges ?
    For to answer this, you will need to search in your local stores and on-line to see if there is a popular replacement option available. You should pay particular care to whither the cartridges require a chip or not.
  5. Is there a CISS option
    Now you need to check for a CISS supplier and to see whither they have a supported model for your printer and if there is instruction videos on how to install them
    For my purposes "City Ink Express" fitted the bill on both counts. They are a UK store and the only purchase I made arrived before the printer I ordered and the ink system seems to work fine.

Brother MFC-J5910DW

I ended up going with the "Brother MFC-J5910DW" as we were looking for a printer that could scan to the network, print A3, A4 duplex, as well as supporting Linux. At the time of writhing the Brother printers do not use any chips and allow you to replace the cartridges. One annoying thing was that when the ink in one of the supplied cartridges went empty (after printing 10 A3 pages), it no longer allowed me to scan to the network. Fortunately I had the CISS system ready to rock and to be honest I was dreading installing it.

Even if you don't want to purchase your CISS system from City Ink Express, you should have a look at their videos. For my printer there were three that were appropriate, namely how to Fill and prime it, how to install it and (for the future) how to refill it. I'm not going to waste time on my experiences as I have nothing to add to the videos other than to say, you may want to put on a pair of gloves and do your work over a news paper to capture any ink that spills.

I'm not using the system or the printer long enough to give a full review but the CISS system has saved two birthday parties so not a bad start.

hpr1470 :: Learn to read time with ccClock

Released on 2014-03-21 under a CC-BY-SA license.

Over the years the image of the clock has been abstracted and stylized to a point where a long and a short line inside a circle, or even inside four dots on the ordinals, can be instantaneously recognized as a clock. This is perfectly fine if you already know how to read the analog clock but it makes no sense to use such a design as a teaching aid.

oval with two hands Creative Commons Clock

As a teaching device, you need to make sure all the information that has been abstracted away has been put back.

That is the basic principle of the ccClock

  • The minute hand points at the minute dial
  • All the minutes are listed removing the need to know the 5 or 15 math table
  • The Clockwise direction is emphasized with arrows and text orientation.
  • The two per day rotation of the hour hand is described using a concentric spiral
  • The progression of day into night is indicated by recognizable icons of the rising and setting sun and moon
  • The written format is described in the traditional dial digits
  • The spoken form is described in speech balloons

01:05:30 XMPP realtime lounge

Lights, Sensors, Switches, Dimmers and of course the obligatory RaspberryPi and a bread board. So what is this you ask ? Well Ralph Meijer, Edwin Mons and Joachim Lindborg explain the "Internet of things" and how they want to use the XMPP protocol to "chat" with your devices. The plan is simple: set-up each device so it can talk to XMPP, then you can use Jabber or any other XMPP client to talk to them.

The lads from the XMPP realtime lounge

The Extensible Messaging and Presence Protocol (XMPP) is an open technology for real-time communication, which powers a wide range of applications including instant messaging, presence, multi-party chat, voice and video calls, collaboration, lightweight middleware, content syndication, and generalized routing of XML data. The technology pages provide more information about the various XMPP “building blocks”. Several books about Jabber/XMPP technologies are available, as well.


01:24:09 Jitsi

We have a chat with Emil Ivov, the project lead of Jitsi.

Jitsi (formerly SIP Communicator) is an audio/video and chat communicator that supports protocols such as SIP, XMPP/Jabber, AIM/ICQ, Windows Live, Yahoo! and many other useful features. Jitsi is Open Source / Free Software, and is available under the terms of the LGPL.

00:56:14 Puppet

Over at the Puppet booth we talk to Eric Sorenson from PuppetLabs and Bert Van Vreckem from the Belgium Puppet user group.

Puppet Open Source is a flexible, customizable framework available under the Apache 2.0 license designed to help system administrators automate the many repetitive tasks they regularly perform. As a declarative, model-based approach to IT automation, it lets you define the desired state - or the “what” - of your infrastructure using the Puppet configuration language. Once these configurations are deployed, Puppet automatically installs the necessary packages and starts the related services, and then regularly enforces the desired state. In automating the mundane, Puppet frees you to work on more challenging projects with higher business impact. Puppet Open Source is the underlying technology for Puppet Enterprise and runs on all major Linux distributions, major Unix platforms like Solaris, HP-UX, and AIX, and Microsoft Windows.

Next we spoke to the Erik Josefsson about the need for as many people as possible to register as a Supporter of Free Software on the spfsug website. Please take some time to do that now.

The European Parliament Free Software User Group is an open community of staff, assistants and Members of the European Parliament, and of supporters from the free software community. Its goals are to:

  • Assist people interested in using free software in the European Parliament
  • Drive adoption of free software in the European Parliament's information infrastructure
  • Push for use of open standards, to ensure equal access for citizens using free software
  • Work in cooperation with like-minded groups in Europe and around the world


00:27:07 KDE

Over at the KDE booth, I managed to track down Jonathan Riddell about the KDE project. From Wikipedia:

KDE (/?ke?di??i?/) is an international free software community producing an integrated set of cross-platform applications designed to run on Linux, FreeBSD, Solaris, Microsoft Windows, and OS X systems. It is known for its Plasma Desktop, a desktop environment provided as the default working environment on many Linux distributions, such as openSUSE, Mageia and Kubuntu and is default desktop environment on PC-BSD a BSD operating system.
The goal of the community is to provide basic desktop functions and applications for daily needs as well as tools and documentation for developers to write stand-alone applications for the system. In this regard, the KDE project serves as an umbrella project for many standalone applications and smaller projects that are based on KDE technology. These include Calligra Suite, digiKam, Rekonq, K3b, and many others.
KDE software is based on the Qt framework. The original GPL version of this toolkit only existed for the X11 platform, but with the release of Qt 4, LGPL versions are available for all platforms. This allows KDE software based on Qt 4 to also be distributed to Microsoft Windows and OS X.

About KDE

The KDE Community is an international technology team dedicated to creating a free and user-friendly computing experience, offering an advanced graphical desktop, a wide variety of applications for communication, work, education and entertainment and a platform to easily build new applications upon. We have a strong focus on finding innovative solutions to old and new problems, creating a vibrant atmosphere open for experimentation.

About Kubuntu

Kubuntu is an operating system built by a worldwide team of expert developers. It contains all the applications you need: a web browser, an office suite, media apps, an instant messaging client and many more. Kubuntu is an open-source alternative to Windows and Office.


00:50:13 Drupal

Bumping into old friends is all part of the FOSDEM experience. Never one for missing an opertunity to turn a chat into an episode, I catch up with Paul Krischer, who tells us about his work with Drupal. Keep your diary clear for drupalcon Amsterdam, which will be held 29 SEP - 03 OCT.

Drupal is an open source content management platform powering millions of websites and applications. Its built, used, and supported by an active and diverse community of people around the world.


00:55:00 Mozilla

After a long night "discovering" Brussels using the public transport system, we track down Brian King the European Community Builder for Mozilla. We talk about the Mozilla phone.

The mozilla team.

At Mozilla, were a global community of technologists, thinkers and builders working together to keep the Internet alive and accessible, so people worldwide can be informed contributors and creators of the Web. We believe this act of human collaboration across an open platform is essential to individual growth and our collective future.


01:07:09 GNOME

We talk to Tobias Mller who is on the board of directors for the GNOME project.

GNOME 3 is an easy and elegant way to use your computer. It is designed to put you in control and bring freedom to everybody. GNOME 3 is developed by the GNOME community, a diverse, international group of contributors that is supported by an independent, non-profit foundation.


01:12:52 CentOS

Starting a series of RedHat interviews we interview Jim Perrin Governing Board member of the CentOS project.

The CentOS trio.

The CentOS Linux distribution is a stable, predictable, manageable and reproduceable platform derived from the sources of Red Hat Enterprise Linux (RHEL). We are now looking to expand on that by creating the resources needed by other communities to come together and be able to buld on the CentOS Linux platform. And today we start the process by delivering a clear governance model, increased transparency and access. In the coming weeks we aim to publish our own roadmap that includes variants of the core CentOS Linux.


01:23:08 RedHat: Foreman, oVirt, and Open Stack

Daniel Lobato and Doran Fedu help me understand what Foreman, oVirt, and OpenStack is all about.


Foreman is an open source project that gives system administrators the power to easily automate repetitive tasks, quickly deploy applications, and proactively manage servers, on-premises or in the cloud. (From Wikipedia) Foreman (also known as The Foreman) is a complete life cycle systems management tool for physical and virtual servers with deep integration to configuration management software, specifically Puppet. The Foreman provides provisioning on bare-metal (through managed DHCP, DNS, TFTP, and PXE-based unattended installations), virtualization and cloud. The Foreman provides comprehensive, auditable interaction facilities including a web frontend, command line interface and robust, REST API.


oVirt manages virtual machines, storage and virtualized networks. (From Wikipedia) oVirt is a free platform virtualization management web application community project started by Red Hat. oVirt is built on libvirt which could allow it to manage virtual machines hosted on any supported backend, including KVM, Xen and VirtualBox. However, oVirt is currently focused on KVM alone. oVirt is an open source software with backing from Red Hat and it is the base for Red Hat Enterprise Virtualization.


OpenStack is a cloud operating system that controls large pools of compute, storage, and networking resources throughout a datacenter, all managed through a dashboard that gives administrators control while empowering their users to provision resources through a web interface.


01:48:17 Fedora

Completing (for the most part) the RedHat thread we head over to the Fedora Project booth and talk to Ji? Eischmann and Jaroslav ?eznk. Ji? is the chair of the Fedora Ambassador Steering Committee, and works for RedHat as a Community Manager. Jaroslav is the Fedora Program Manager.

Fedora Friends

Fedora is a fast, stable, and powerful operating system for everyday use built by a worldwide community of friends. It's completely free to use, study, and share.

Jeremy Allison ~ the SAMBA project

Ken Fallon interviews Jeremy Allison

For some reason my Zoom H2 failed to record this interview. Based on past experience I'm more inclined to blame the operator than the device so the audio is taken from the backup recording device, a Sansa Clip. As we say at HPR, any recording is better than no recording so any strange audio artefacts are a result of that.

00:00:30 Introduction

Ken and Dave introduce the show

00:01:55 FOSDEM Volunteers

The first chat was with Kristof Provost. By day a Embedded Software Engineer, but at fosdem he transforms into a cloak room attendant and we chat about how you can help out at FOSDEM.

00:04:52 OSGeo project

Next was a chat with Anne Ghisla from the OSGeo project.

The Open Source Geospatial Foundation
OSGeo was created to support the collaborative development of open source geospatial software, and promote its widespread use. Join us by signing up to our mailing lists or check out the Getting Started page to become more involved.

Dirk Frigne and Anne Ghisla

00:08:29 Geomajas

Sample folders at the booth

Following on we talk to Dirk Frigne

What is Geomajas?
Geomajas is an enterprise-ready open source GIS framework for the web. It has client-server integration for displaying and editing of geographic data.
Geomajas has integrated security and is endlessly scalable. It is compliant with OGC standards such as WMS, WFS, etc and also supports spatial databases.
It integrates with your system and provides out-of-the-box functionality through plug-ins. By leveraging GWT on the client, development is all-Java making it easier and more efficient for your team.

00:16:09 OpenStreetMap

Last in the mapping trio we speak to Gaël Musquet, président d'OpenStreetMap France.

Open Street Map demos Sat devices

The tuner referred to in the interview

The pc referred to in the interview

OpenStreetMap powers map data on hundreds of web sites, mobile apps, and hardware devices. OpenStreetMap is built by a community of mappers that contribute and maintain data about roads, trails, cafés, railway stations, and much more, all over the world.

00:39:46 Libre Graphics magazine

Changing the pace from mapping we get to talk with ginger "all-lower-case" coons :) about producing the Libre Graphics magazine using all Free Software

A Libre Graphics Magazine is long overdue. In a market dominated by magazines devoted to design discourse built around proprietary tools and the latest computer graphics tricks and techniques, users of Libre Graphics software are underserved and unrecognized. We know that these users exist, both professionally and as hobbyists. We know this because we are they. We are graphic designers, media artists, photographers and web designers. We use Libre Graphics software, quietly and without regard. Our peers, used to proprietary alternatives, question our choice of tools. Our work, when executed well, is indistinguishable from work produced by more traditional means. Thus, our choices are invisible, unless we make an issue of them.

00:45:18 openSUSE

Next we talk to Richard Brown one of the board members of the openSUSE team.

openSUSE is a free and Linux-based operating system for your PC, Laptop or Server. You can surf the web, manage your e-mails and photos, do office work, play videos or music and have a lot of fun!

00:56:48 The Debian Project

Debian developer and T-Shirt salesman, Joost van Baal-Ilić takes some time away from the booth to give us the run down on Debian.

The Debian Project is an association of individuals who have made common cause to create a free operating system. This operating system that we have created is called Debian. An operating system is the set of basic programs and utilities that make your computer run. At the core of an operating system is the kernel. The kernel is the most fundamental program on the computer and does all the basic housekeeping and lets you start other programs. Debian systems currently use the Linux kernel or the FreeBSD kernel. Linux is a piece of software started by Linus Torvalds and supported by thousands of programmers worldwide. FreeBSD is an operating system including a kernel and other software.

01:08:04 HelenOS

Google Summer of Code mentors Martin Děcký, and Jakub Jermář talk to us about HelenOS, a project which has mentored GSOC student coders.

Martin Děcký, and Jakub Jermář

HelenOS Screen Shot

HelenOS is an operating system based on a multiserver microkernel design. Rather sooner than later, HelenOS will become a complete and usable modern operating system, offering room for experimenting and research. HelenOS uses its own microkernel written from scratch and supports SMP, multitasking and multithreading on both 32-bit and 64-bit, little-endian and big-endian processor architectures, among which are AMD64/EM64T (x86-64), ARM, IA-32, IA-64 (Itanium), 32-bit MIPS, 32-bit PowerPC and SPARC V9. Thanks to the relatively high number of supported architectures and suitable design, HelenOS is very portable. On top of the microkernel, HelenOS provides services such as file systems, networking, device drivers and user interface. Most of these services are composed of multiple independent server processes, which makes HelenOS one of the most modular operating systems.

01:23:28 CAcert

I took Michael Tänzer away from checking passports and drivers licenses to explain to us what's the idea behind is a community driven Certificate Authority that issues certificates to the public at large for free. CAcert's goal is to promote awareness and education on computer security through the use of encryption, specifically with the X.509 family of standards. We have compiled a document base (Wiki) that has helpful hints and tips on setting up encryption with common software, and general information about Public Key Infrastructures (PKI). CAcert Inc. is a non-profit association, incorporated in New South Wales, Australia.

hpr1344 :: Filming a Dinosaur egg hatching

Released on 2013-09-26 under a CC-BY-SA license.

In this episode Ken and his Son hatch a plan to film a Dinosaur egg hatching using fswebcam.

Groeiend Dinosaurus Ei

We had to wait 8 days for a Dinosaur egg to hatch, so we rigged up a RasberryPi with a cheap usb cam to take pictures. This was just before the camera module was releases. However the principle was the same. We positioned the egg in a mixing bowl and placed it on some boxes to give it height. Then we used the handle of a camera stand as a place to clip on a cheap usb camera. We then connected the camera to a RasberryPi.

the camera rig

On the first day we let the light in and you see flickering as the lighting conditions change over the course of the day and the camera adjusts. Peter64 has promised a episode on how to fix this. So we closed the curtains and added an artificial light source as can be seen below.

While we could have used fswebcam to automatically take the pictures, there was a certain satisfaction in seeing the program run every minute. Other than the default rasbian install, we installed fswebcam and screen. The first to take the pictures and the other to allow the script to continue running after we disconnected.

$ cat egg.bash
while true
  nowdate=$(date -u +%Y-%m-%d_%H-%M-%SZ_%A)
  echo ${nowdate}
  fswebcam -r 640x480 \
           -S 15 \ 
           --flip h \
           --jpeg 95 \
           --shadow \
           --title "Dinosaur Hatching" \
           --subtitle "Pádraig Fallon" \
           --info "" \
           --save egg-${nowdate}.jpg
  sleep 1m

That produced a big long list of images, 10886 in total, and it was a "simple" matter to convert them to a mp4 file with ffmpeg. See for more information on encoding for the web in general

ffmpeg -y -r 120 -f image2 -pattern_type glob -i "*.jpg" -b:v 2000k -vcodec libvpx -quality best egg-libvpx.webm

hpr1340 :: Out and about at OHM 2013

Released on 2013-09-20 under a CC-BY-SA license.


OHM2013. Observe, Hack, Make. A five day outdoor international camping festival for hackers and makers, and those with an inquisitive mind. On 31st July 2013, 3000 of those minds will descend upon on an unassuming patch of land, at the Geestmerambacht festival grounds, 30km north of Amsterdam.

It is a four year tradition in The Netherlands to hold such an event. In the spirit of WTH, HIP and HAR the latest edition, OHM2013, is a non-commercial community run event. The event happens thanks to the volunteers, all 3000 of them. They will run the network, help people around the site, give talks, hold workshops and be excellent to one another.

The target audience includes free-thinkers, philosophers, activists, geeks, scientists, artists, creative minds and a whole bunch of people interested in lots of interesting stuff.

Lock Picking

First port of call is a lock picking in a tent. Although lacking modern conveniences like, for example, doors, Nigel and the team has assembled a selection of locks for all levels. For more information contact Nigel Tolley from Discreet Security Solutions:
Follow @discreetsecure on Twitter

Rainbow Island

Next stop "Rainbow island" for a chat with Johan, Brenn, Stitch and Joob.

Rainbow Island is possibly the most modest project you’ll see at OHM2013. Obviously, in this context, possibly means absolutely, and modest means insane.

The 2,500 sqm island on field R will be adorned by an immense castle-like structure, with towers that reach five meters into the air. In daylight, you’ll see just a marble-white castle. But at night, it turns into an oasis, nay, orgasm of colours, video projections, smoke, and laser-beams.

Inside the castle, several tents will be raised, containing all kinds of art and entertainment.

The first tent will host vintage pinball and arcade machines. But these are not just for mindless consumerism! There will be a large pinball-repair station, where these old machines can get the TLC they so often need. Bring your multi-meter, spare parts, screwdrivers, and hack away! There will be a number of machines eligible for improvement.

The second pair of tents will contain the complete collection of Awesome Retro, a group of retro-gaming enthusiasts who collect everything regarding gaming, as long as it’s over a decade old. You’ll find classics like Super Mario Kart and Bomberman, the first editions of Pong and Pac-Man, and a lot of other blasts from the past, which will wrap you like the warm blankets that they are. Besides that, you’ll find a fine collection of ultra-high-end Personal Computers, but to year-2000 standards, of course. A game of Quake 1 multiplayer, anyone?

A small and informal stage surrounded by sofas will also be available for competitions and presentations. In the time in between events, this “living room” is free to use as a cosy lounge. Because what better way to enjoy gaming than from a sofa, with friends, whilst eating crisps?

Rainbow Island sketchup april

And that is all, you think? Think again, because this is Rainbow Island, where the word “boundary” got scratched from the dictionary!

First of all, numerous smaller tents will be put up within the walls of the castle, consisting of the essentials of multi-player retro-gaming: comfy four-seater sofa, game console, great 4-player game, four controllers, a TV… and projector! Yes, the games will be projected on the castle walls, which are semi-transparent, so even people on the outside will be able to enjoy the competitions.

Next, the interiors of the four castle towers are available for all kinds of arts and other projects. These towers are 4 by 4 meters wide, and can be entered at the ground level. You may claim these for your own projects!

Other highlights which are in the process of being perceived –or otherwise prepared– are a life-size model of a CRAY-1 supercomputer, Operation Oversight (a master-control room putting you in the driver’s seat of the world’s super powers), and of course the results of the Dance Dissect Repurpose competition.

Next we have a chat with Jeff POINCARE who was building a seat shaped like a Cray 1.
From Wikipedia, the free encyclopedia The Cray-1 was a supercomputer designed, manufactured and marketed by Cray Research. The first Cray-1 system was installed at Los Alamos National Laboratory in 1976 and it went on to become one of the best known and most successful supercomputers in history. The Cray-1's architect was Seymour Cray, the chief engineer was Cray Research co-founder Lester Davis.

BruCON is an annual security and hacker conference providing two days of an interesting atmosphere for open discussions of critical infosec issues, privacy, information technology and its cultural/technical implications on society. Organized in Belgium, BruCON offers a high quality line up of speakers, security challenges and interesting workshops. BruCON is a conference by and for the security and hacker community.

The conference tries to create bridges between the various actors active in computer security world, included but not limited to hackers, security professionals, security communities, non-profit organizations, CERTs, students, law enforcement agencies, etc.....

Hackers are "persons who delight in having an intimate understanding of the internal workings of a system, computers and computer networks in particular." People who engage in illegal activities like unauthorized entry into computer systems are called crackers and don't have anything to do with hacking. BruCON doesn't promote any illegal activities and behavior. Many hackers today are employed by the security industry and test security software and systems to improve the security of our networks and applications. In addition, for the younger generations, we want to create some awareness and interest in IT students to learn more about IT Security.

Trainings are planned for Sep 24-25, the conference for Sep 26-27. BruCON 2012 will be in the historic center of Ghent, Belgium.


Then off to the BlinkenArea to learn how to solder under the able eye of Arne Rossius.

Welcome in the BlinkenArea, the portal for "blinken" [=flashing/sparkling/blinking] projects. The BlinkenArea is a project group of people who are interested in computers and electronics and in a creative handling of both of it. They attend to the research and operation of flashing projects. In the meantime, more than 60 hard- and software projectes were developed. The group grows constantly and the number of small and big projects rises as well. The major projects have been the pixel room TROIA and the display building bluebox. Detailled information about all projects is available on the page Projects. News are always published in the BlinkenArea Blog.

Origin and motivation

The page BlinkenArea tells you more about history, background and motivation. Apart from realising projects, the BlinkenArea people set their sights on collecting money which is scheduled to flow into public welfare, e.g. by selling own developed assembly kits or campaigns within bigger projects. The attention is focussed on supporting children, fighting against poverty and spreading education. Information about the social engagement of the BlinkenArea people can be found on the page Campaign. The BlinkenArea set further objectives which are listed on the page Goals.


Everybody who is interested in our "blinken" projects and wants to contribute or support our honorary work is cordially welcomed. We are always looking for software engineers, tinkerer, translators, news editors, designer, musicians (set movies to music), and -- of course -- new projects. If you want to join the BlinkenArea, please visit the page Join. The BlinkenArea runs a Mailinglist and a discussion forum where you can ask questions, join in the conversation or just read along.


Information for journalists and editors is available on the page Press.

PyOpenCL lets you access the OpenCL parallel computation API from Python. Here's what sets PyOpenCL apart:

  • Object cleanup tied to lifetime of objects. This idiom, often called RAII in C++, makes it much easier to write correct, leak- and crash-free code.
  • Completeness. PyOpenCL puts the full power of OpenCL’s API at your disposal, if you wish.
  • Convenience. While PyOpenCL's primary focus is to make all of OpenCL accessible, it tries hard to make your life less complicated as it does so--without taking any shortcuts.
  • Automatic Error Checking. All OpenCL errors are automatically translated into Python exceptions.
  • Speed. PyOpenCL’s base layer is written in C++, so all the niceties above are virtually free.
  • Helpful, complete documentation and a wiki.
  • Liberal licensing (MIT).


PyCUDA lets you access Nvidia‘s CUDA parallel computation API from Python. Several wrappers of the CUDA API already exist–so what's so special about PyCUDA?

  • Object cleanup tied to lifetime of objects. This idiom, often called RAII in C++, makes it much easier to write correct, leak- and crash-free code. PyCUDA knows about dependencies, too, so (for example) it won’t detach from a context before all memory allocated in it is also freed.
  • Convenience. Abstractions like pycuda.driver.SourceModule and pycuda.gpuarray.GPUArray make CUDA programming even more convenient than with Nvidia’s C-based runtime.
  • Completeness. PyCUDA puts the full power of CUDA’s driver API at your disposal, if you wish.
  • Automatic Error Checking. All CUDA errors are automatically translated into Python exceptions.
  • Speed. PyCUDA’s base layer is written in C++, so all the niceties above are virtually free.
  • Helpful Documentation.

EMF Camp

Alec Wright ( and Chris Munroe (@chrismunro40x) make the mistake of giving me a leaflet.

Electromagnetic Field (EMF) is a non-profit UK camping festival for those with an inquisitive mind or an interest in making things: hackers, geeks, scientists, engineers, artists, and crafters.

In the summer of 2012 we gathered hundreds of people in a field outside Milton Keynes for three days of talks and workshops covering everything from genetic modification to electronics, blacksmithing to high-energy physics, reverse engineering to lock picking, computer security to crocheting, and quadcopters to beer brewing.

To help matters along, we arranged a 380-megabit internet connection, reliable WiFi, and a bar stocked with real ale.

Meanwhile Robert Fitzsimons is slaving away in the hardware hacking tent and gives us a rundown of his projects on display.

Open Garage

The "Open Garage" is a double garage in Borsbeek, Belgium, some sort of hackerspace, where I host weekly workshops and many of my projects. The garage is open every Thursday evening to everyone who wants to join our community's numerous hacking projects.

Just be excellent to each other (principle #1 out of 1), bring a drink, a project and a friend and we're all set.

I have all the tools and basic stock for elementary wood and metal working. Electronics gear and misc materials are available to tackle various projects. I also run a nano brewery from my garage, try to convert a car to electric, have a printrbot/Wallace++ 3D printer and we are trying to get a professional CNC mill and CNC lathe to work and I want to build a toolset for some DIY biotech, among many other things.

Projects that have been successfully tackled or demoed at the garage are 3D printers and CNCs, a weather balloon, quadcopters, soldering and welding tutorials, a Tesla coil, beer brewing, a compost filtering machine, Arduino and Raspberry Pi projects, a windbelt, a Rubens' tube and many tens of other thingamajigs.

For those that may be new and interested: There's usually a few technology-minded people that drop by on random Thursday evenings with "goesting" to make. Some people bring a project and others bring their skills to collaborate on others' projects. (and there's a lot of nerd talk) If you're into that kind of stuff, feel free to drop by.

It is NOT required for your skills be on a high level, you are NOT required to contribute knowledge; instead, it is encouraged that everyone LEARNS stuff at our gatherings.

I'd like to push my regulars to RSVP to the events, there's a lot of useful features in Meetup to share all kinds of stuff if you become part of the game ...

Released on 2013-07-10 under a CC-BY-SA license.

Slowly but surely over the almost 15 years of his stay in the Netherlands, Ken has been Dutchafied. He's got a bakfiets, he learned the language(ish), he has a pair of wooden shoes, he even eats mayonnaise with his fries. But one thing he has rebelled against is camping (ok also Steak Tartare aka 'American Fillet' aka raw cow). That most Dutch of traditions, where the family head off to some deserted field, be it by the sea, in a forest, or on the polder, one thing is sure, it will be damp, wet, mosquito ridden, dark too late and bright too early, and wet - optionally cold and hot. In short hell. Of course that's his personal opinion.

Of course, Nido Media sees it as a relaxing vacation away from the hustle and bustle of a busy life, fortified with happy memories where he and his family enjoyed the long summers days when it never rained and they were allowed to stay up late.

So how can these two dividing opinions be bridged ?

In short: Fiber to the Tent.

Released on 2013-04-01 under a CC-BY-SA license.

In this the first in a series exploring The Open Systems Interconnection (OSI) model (ISO/IEC 7498-1)

OSI model
From Wikipedia, the free encyclopedia

The Open Systems Interconnection (OSI) model (ISO/IEC 7498-1) is a product of the Open Systems Interconnection effort at the International Organization for Standardization. It is a prescription of characterizing and standardizing the functions of a communications system in terms of abstraction layers. Similar communication functions are grouped into logical layers. A layer serves the layer above it and is served by the layer below it.

For example, a layer that provides error-free communications across a network provides the path needed by applications above it, while it calls the next lower layer to send and receive packets that make up the contents of that path. Two instances at one layer are connected by a horizontal connection on that layer.

In today's show Ken starts off with a practical example of Layer One, the The Physical Layer, Although we are limited to audio for the purposes of the show, the same techniques could and are used across the light spectrum.

A big line of people with spades

Located in the very pretty but the rural Forest of Bowland in Lancashire in the UK, and tired of putting up with slow ''broadband'' they decided to put together their own network. They tried shared wifi, 3 and 4G mobile networks, MMDS and Satellite yet all proved to be unreliable.

So over tea and cake they came up with a plan.

  • A 240 Kilometer (150 mile) plan.
  • A 1 gigabit (1000mb/sec) fiber optic connection plan.
  • A let''s give a connection to every one of the 1700 homes, farms, schools, churches and businesses, in the area plan
And while they were at it they designed it to be:
  • redundant with a dual homed backbone direct to the UK''s Internet exchange
  • upgradeable with ducts large enough to take multiple fibers
  • laid through some of the most rugged, mountainous area of Lancashire to get to the people that need it most. (And let''s be clear here, nothing to do with the fact that they will need to use dynamite to blast their way through the rocks.)

hpr1060 :: OggCamp12 Farewell

Released on 2012-08-24 under a CC-BY-SA license.

I was leaving my hotel room after the end of OggCamp, thinking to myself I had enough interviews recorded and something made me go back and get my recorders. I'm glad I did as I bagged some fantastic interviews.

The first one was with Rebecca Newborough web mistress of the Lincoln LUG on how to start a lug. The first step is to visit the UK Linux User Groups site at

We all went to the Leaf venue for food and conversation, while there I interviewed a few gentlemen starting with Kris Findlay about changes at his LUG and his work at Krisilis IT Solutions
Raspberry Pi GPIO Demo

The Software Society

Then we had a chat with Ian Closs over from Ireland. We discussed the local FLOSS scene, Mark Shuttleworth who will be attending SkyCon and Archeology.

To round it all off a long round up with Fabian A. Scherschel who true to his word gave me an interview for HPR. Of course he is still on record to submit a show to HPR himself.

You might think that's the end of OggCamp but I still have shows from last year to post :)

hpr1034 :: PXE Boot

Released on 2012-07-19 under a CC-BY-SA license.

In todays show, Ken tells of his struggle to get silent PC to work with his spare 17" monitor. His attempts to get a "VIA EPIA M9000 Mini ITX Motherboard" failed miserably and so he has turned to a HP Compaq t5000 thin client. As can be seen in this post here and discussed here.

The OS installs fine from USB but you run into grub issues on reboot that require you to boot from USB disk to rectify and that runs into problems as the boot order get's confusing. To get around this I decided to install Debian via PXE boot or more commonly "Pixie" boot. A full description can be found on the debian wiki. Basically it involves setting up a DHCP server, a TFTP server and downloading a boot image.

Once you have everything configured is a standard Debian net install. The only gotya is entering the MAC address of your Client and making sure you know what is happening on your network with regard to DHCP. I set the internal sd drive as the boot partition, created a 500Mb swap on my 4G external disk and put the root as the rest. I set both the boot and the root partition to ext2 as I didn't want the added strain of journaling on the sd media.

I ran into the Grub 2 ERROR 17 issue which meant that I had to do some reading on Grub2 and we're back to the bad old days of lilo where you need run commands or your config changes are ignored. Anyway another Pixie boot, this time into recovery mode long enough to type update-grub. A quick reboot and we're into a standard Debian base install.

I took the steps to installing Debian multimedia by adding the magic deb squeeze main non-free to my /etc/apt/sources.list and then doing

aptitude install debian-multimedia-keyring
to get the keyring in order. After that it was a aptitude update and a aptitude safe-upgrade and that was it. I was free to install anything I wanted.


hpr1027 :: Migrating away from Google Reader

Released on 2012-07-10 under a CC-BY-SA license.

One of the major advantages of Google Reader over application based clients is that no matter where you access it from your views are synchronized. Everything you read is marked a read everywhere and you don't have to worry about whither you check your feeds on a desktop PC or on your phone. It truly is the best example of a cloud application out there.

Except for the fact that I'm not happy with the idea of a complete stranger watching and recording every article I read, how long I read it for, and share that information around to other trusted partners. Remember when your parents/guardians caught you reading over their shoulder ? It wasn't acceptable then and it sure isn't now. Epically when I noticed that my search results changed dramatically after I started following certain feeds. It's just not right and here's why

Getting a list of my feeds

Google should be credited with the fact that they make exporting very easy to do. Thanks to the work of the team. Who's stated goal is "Users should be able to control the data they store in any of Google's products. Our team's goal is to make it easier to move data in and out."
For Google Reader this amounts to:

Settings -> Reader Settings -> Import/Export -> OPML

OPML (Outline Processor Markup Language) is an XML format for outlines (defined as "a tree, where each node contains a set of named attributes with string values"). Originally developed by Radio UserLand as a native file format for an outliner application, it has since been adopted for other uses, the most common being to exchange lists of web feeds between web feed aggregators.
From Wikipedia, the free encyclopedia

That's it. You now have a list of all your feeds we are still faced with the problem of reading/deleting items in one place and having them synchronized everywhere else ? The answer is actually quite obvious.

imap - Internet Message Access Protocol

From Wikipedia, the free encyclopedia
Internet message access protocol (IMAP) is one of the two most prevalent Internet standard protocols for e-mail retrieval, the other being the Post Office Protocol (POP). Virtually all modern e-mail clients and mail servers support both protocols as a means of transferring e-mail messages from a server.

The great news is that there are imap clients everywhere. Microsoft Outlook supports it. Thunderbird, Evolution, Kmail, Claws-Mail all support it. It's supported on Android, the iPhone, and on Windows Mobile. There are a multitude of web clients. The only problem now was to find a way to get the RSS feeds over to a imap message format. A quick duckduckgo search later lead me to ....

Feed2Imap is an RSS/Atom feed aggregator. After Downloading feeds (over HTTP or HTTPS), it uploads them to a specified folder of an IMAP mail server or copies them to a local maildir. The user can then access the feeds using Mutt, Evolution, Mozilla Thunderbird or even a webmail.

It's in all the major repositories and I had it up and running in under ten minutes. It keeps it's settings in a hidden file .feed2imaprc in your home directory. The configuration is simple, four lines per feed.

 - name:
   target: imap://
   include-images: true

The name filed is what will be the feed name and url is the link to the rss feed. The target is the path on the imap account you want to put it to. I used a throw away email account on my own domain with some restrictions on the size so that if I forget to check it won't affect the rest of my mailboxes.
The line it's broken into several parts, first is imap:// followed by the imap account user name and password. If your login contains an @ character, replace it with %40. Next is the @ sign followed by your server hostname and then the path. I chose INBOX.Feeds and then a subfolder for every group I had in Google Reader. The only other option I set was to include the images.


I have quite a few feeds now and I did not want to be typing them in by hand. So I wrote a small perl script to convert the opml file into a .feed2imaprc format and it will hopefully get you most of the way. The code is available on ( thanks to Klaatu over at where he covered using Git in the March 31, 2012: Episode 7x13.)

Now setup the imap account on your mail client(s) and once you are happy run feed2imap and you should see the items beginning to appear. I set it to run every two hours at 14 minutes past the hour by adding the following line to my cron tab.

14 */2 * * * /usr/bin/feed2imap >/dev/null 2>&1

hpr0995 :: Do the four freedoms extend beyond software ?

Released on 2012-05-24 under a CC-BY-SA license.

On Linux For The Rest Of Us #74 - The Legistrative Session, one of our correspondents Mr. Gadgets, called in the following question. The segment begins at at 01:00:30 and in it he describes a conversation about the four freedoms where someone who's opinion he respected stated "the four freedoms only cover programming. It is only the code that is covered in the four freedoms".

For those of you who don't know The Free Software Definition boils down to the following rules:

  • Freedom 0: The freedom to run the program for any purpose.
  • Freedom 1: The freedom to study how the program works, and change it to make it do what you wish.
  • Freedom 2: The freedom to redistribute copies so you can help your neighbor.
  • Freedom 3: The freedom to improve the program, and release your improvements (and modified versions in general) to the public, so that the whole community benefits.

If you read the The Free Software Definition, then yes all the references are to "software" only....
...that is of course until you get to the section Beyond Software, in the same document, which states:

Software manuals must be free, for the same reasons that software must be free, and because the manuals are in effect part of the software.
The same arguments also make sense for other kinds of works of practical use - that is to say, works that embody useful knowledge, such as educational works and reference works. Wikipedia is the best-known example.
Any kind of work can be free, and the definition of free software has been extended to a definition of free cultural works applicable to any kind of works.

So in summary, as HPR is now released under a Creative Commons Attribution-ShareAlike 3.0 Unported lisence, any shows that provide useful knowledge, such as educational works and reference works are covered by the four freedoms.

hpr0967 :: Raspberry Pi spec review

Released on 2012-04-16 under a CC-BY-SA license.

Raspberry Pi Board IO OverviewIn todays show Klaas-Jan walks Ken throught the possibilities of the Raspberry Pi. The Raspberry Pi is a credit-card sized computer that plugs into your TV and a keyboard. It’s a capable little PC which can be used for many of the things that your desktop PC does, like spreadsheets, word-processing and games. It also plays high-definition video. We want to see it being used by kids all over the world to learn programming. All for under $35.


RCA connector
Composite video is the format of an analog television (picture only) signal before it is combined with a sound signal and modulated onto an RF carrier. In contrast to component video (YPbPr) it contains all required video information, including colors in a single line-level signal. Like component video, composite-video cables do not carry audio and are often paired with audio cables (see RCA connector).

A photo of a HDMI connector
HDMI (High-Definition Multimedia Interface) is a compact audio/video interface for transmitting encrypted uncompressed digital data. HDMI implements the EIA/CEA-861 standards, which define video formats and waveforms, transport of compressed, uncompressed, and LPCM audio, auxiliary data, and implementations of the VESA EDID. HDMI supports, on a single cable, any uncompressed TV or PC video format, including standard, enhanced, high definition and 3D video signals; up to 8 channels of compressed or uncompressed digital audio; a Consumer Electronics Control (CEC) connection; and an Ethernet data connection.

General Purpose Input/Output (a.k.a. GPIO) is a generic pin on a chip whose behavior (including whether it is an input or output pin) can be controlled (programmed) through software.
GPIO pins have no special purpose defined, and go unused by default. The idea is that sometimes the system integrator building a full system that uses the chip might find useful to have a handful of additional digital control lines, and having these available from the chip can save the hassle of having to arrange additional circuitry to provide them. For example, the Realtek ALC260 chips (audio codec) have 4 GPIO pins, which go unused by default. Some system integrators (Acer laptops) employing the ALC260 use the first GPIO (GPIO0) to turn on the amplifier used for the laptop's internal speakers and external headphone jack.

A Universal Asynchronous Receiver/Transmitter, abbreviated UART is a type of "asynchronous receiver/transmitter", a piece of computer hardware that translates data between parallel and serial forms. UARTs are commonly used in conjunction with communication standards such as EIA, RS-232, RS-422 or RS-485. The universal designation indicates that the data format and transmission speeds are configurable and that the actual electric signaling levels and methods (such as differential signaling etc.) typically are handled by a special driver circuit external to the UART.
A UART is usually an individual (or part of an) integrated circuit used for serial communications over a computer or peripheral device serial port. UARTs are now commonly included in microcontrollers. A dual UART, or DUART, combines two UARTs into a single chip. Many modern ICs now come with a UART that can also communicate synchronously; these devices are called USARTs (universal synchronous/asynchronous receiver/transmitter).

I²C ("i-squared cee"; Inter-Integrated Circuit; generically referred to as "two-wire interface") is a multi-master serial single-ended computer bus invented by Philips that is used to attach low-speed peripherals to a motherboard, embedded system, cellphone, or other electronic device. Since the mid 1990s, several competitors (e.g., Siemens AG (later Infineon Technologies AG), NEC, Texas Instruments, STMicroelectronics (formerly SGS-Thomson), Motorola (later Freescale), Intersil, etc.) brought I²C products on the market, which are fully compatible with the NXP (formerly Philips's semiconductor division) I²C-system. As of October 10, 2006, no licensing fees are required to implement the I²C protocol. However, fees are still required to obtain I²C slave addresses allocated by NXP.
SMBus, defined by Intel in 1995, is a subset of I²C that defines the protocols more strictly. One purpose of SMBus is to promote robustness and interoperability. Accordingly, modern I²C systems incorporate policies and rules from SMBus, sometimes supporting both I²C and SMBus with minimal re-configuration required.

Serial Peripheral Interface Bus bus diagram
The Serial Peripheral Interface Bus or SPI (pronounced like "S.P.I." or "spy") bus is a synchronous serial data link standard named by Motorola that operates in full duplex mode. Devices communicate in master/slave mode where the master device initiates the data frame. Multiple slave devices are allowed with individual slave select (chip select) lines. Sometimes SPI is called a "four-wire" serial bus, contrasting with three-, two-, and one-wire serial buses.

Released on 2012-02-08 under a CC-BY-SA license.

In today's show Ken interviews Klaas-Jan Koopman about the Elfstedentocht a particularly Dutch phenomenon. He gives us some background to the tour and tells the story of his Father who has a permit to participate should it go ahead.

This interview was recorded yesterday and since then the organisation committee have said that the tour will not be going ahead this weekend as the ice is not thick enough. We can all wait and see together if it happens or not.


From Wikipedia, the free encyclopedia

The Elfstedentocht (or, in West Frisian, Alvestêdetocht, sometimes in English : Eleven Cities Tour), at almost 200 km, is the world's largest speed skating competition and leisure skating tour, and is held in the province of Friesland, Netherlands only when the ice along the entire course is 15 cm thick.

The tour, almost 200 km in length, is conducted on frozen canals, rivers and lakes between the eleven historic Frisian cities: Leeuwarden, Sneek, IJlst, Sloten, Stavoren, Hindeloopen, Workum, Bolsward, Harlingen, Franeker, Dokkum then returning to Leeuwarden. The tour is not held every year, mostly because not every Dutch winter permits skating on natural ice. The last editions were in 1985, 1986 and 1997. Adding to that, the tour currently features about 15,000 amateur skaters taking part, putting high requirements on the quality of the ice. There is a stated regulatory requirement for the race to take place that the ice must be (and remain at) a minimum thickness of 15 centimetres along the entirety of the course. All skaters must be a member of the Association of the Eleven Frisian Cities. A starting permit is required. Further more, in each city the skater must collect a stamp, as well as a stamp from the three secret check points. The skater must finish before midnight.

hpr0886 :: Product lifecycle management (PLM)

Released on 2011-12-26 under a CC-BY-SA license.

In today's show Ken has a discussion with Alister Munroe about product lifecycle management at OggCamp 11

Product lifecycle management

From Wikipedia, the free encyclopedia

A generic lifecycle of products

PLM In industry, product lifecycle management (PLM) is the process of managing the entire lifecycle of a product from its conception, through design and manufacture, to service and disposal. PLM integrates people, data, processes and business systems and provides a product information backbone for companies and their extended enterprise.

Product lifecycle management (PLM) should be distinguished from 'Product life cycle management (marketing)' (PLCM). PLM describes the engineering aspect of a product, from managing descriptions and properties of a product through its development and useful life; whereas, PLCM refers to the commercial management of life of a product in the business market with respect to costs and sales measures.

Product lifecycle management is one of the four cornerstones of a corporation's information technology structure. All companies need to manage communications and information with their customers (CRM-customer relationship management), their suppliers (SCM-supply chain management), their resources within the enterprise (ERP-enterprise resource planning) and their planning (SDLC-systems development life cycle). In addition, manufacturing engineering companies must also develop, describe, manage and communicate information about their products.

One form of PLM is called people-centric PLM. While traditional PLM tools have been deployed only on release or during the release phase, people-centric PLM targets the design phase. As of 2009, ICT development (EU-funded PROMISE project 2004–2008) has allowed PLM to extend beyond traditional PLM and integrate sensor data and real time 'lifecycle event data' into PLM, as well as allowing this information to be made available to different players in the total lifecycle of an individual product (closing the information loop). This has resulted in the extension of PLM into closed-loop lifecycle management (CL2M).


hpr0883 :: Dan Lynch interview

Released on 2011-12-20 under a CC-BY-SA license.

Today we give you another of the interviews from OggCamp where we interview Dan Lynch. Here's his bio from his own site

Dan Lynch

My cartoon imageHello and welcome, I'm Dan. A writer, musician, developer, broadcaster and hopeless geek from Liverpool in the UK. This site is the hub of everything I do online, or at least it's supposed to be but it still needs work. I'm committed to Free & Open Source Software and Creative Commons, I write and broadcast about both, mainly through the Linux Outlaws and Rathole Radio podcasts. You may also know me as a host of FLOSS Weekly on the TWIT Network.

Rathole Radio is my music show where I play a wide selection of the best music on the net. I interview artists, tell silly stories, have live votes and even play songs myself. The music is very eclectic because I believe that all styles have good and bad within them. I want people to open their minds and not pigeon-hole everything. I only play one "style" of music, stuff I like.

Linux Outlaws is a weekly show where I discuss the latest happenings in the Open Source technology world and with my German co-host and friend Fab. It's grown beyond anything we could have imagined. We get tens of thousands of downloads per show, it's taken me to different parts of the world and allowed me to meet and share time with many of my technology heroes. I'm very lucky. Below you will see the latest content from my blog and both these podcasts. You can also use the links on the menu to find more specialised information about my music and other things.

I sing and play guitar in a band called 20lb Sounds. We recently launched our website with free music downloads and we hope to build up a community there. I'm calling it the 20lb Army, so sign up and join the fun :)

I organised a large Free Software and Free Culture event in Liverpool called OggCamp10. Strange name I know but the site explains all that. It took place on 1st and 2nd of May 2010, we were joined by many great FOSS fans and developers from around the world. Not only that but on Friday April 30th 2010 I also ran a successful Rathole Radio gig with David Rovics and Attila The Stockbroker to kick the weekend off.

I support the Open Rights Group and I'm very concerned about digital rights and political matters in the UK. I'm a proud member of both Liverpool LUG and Chester LUG and regularly attend meetings at both. Is this two timing or just a real commitment to FOSS? I'll let you decide ;)

Thanks for visiting. Feel free to hang around a while and put your feet up.

      There's a lot of great Creative Commons Licensed Music out there, and not enough people know just what you can get hold of! To help ease the burdon of this issue, there are three things that we do:

      • By linking directly to artist's home sites rather than to our own holding pages for artists, we ensure that the artists get maximum exposure for their own material, without having to update our site when their own information changes!
      • By linking to the source of the individual track, gives listeners a greater awareness of music sources, which hopefully should increase the exposure for sites who promote and list Creative Commons licensed music.
      • By linking to podcasts which play Creative Commons licensed music, we give listeners the opportunity to find other shows that play the music they like - ultimately giving listeners a greater fountain of great music to select from, and hopefully giving them the opportunity to discover new artists and genres to add to their personal list of favourites.
    • Support Communities

      An attendor at various social groups, the original author of the code which drives was unable to provide consistent, suitable background music for events he was involved in organising or just attending. This site was originally designed to find tracks which are generally acceptable for public play, and are available under a suitable license for public performance (which Creative Commons music should be!) By asking all submitters of music to identify the license under which the tracks are made available, as well as selecting whether tracks may not be suitable for work or family listening, it should be possible (once the code is in-place) to request from the site a suitable selection of music for playback at venues such as hackspaces, youth centres, or even just hold music for a business. Note that this site is not being created to build a re-licensing business, but instead to promote awareness of great music - there are other, better sites, that can advise and assist in the selection of Creative Commons music which are suitable for your business endeavour, but if you just want something for backing music for an hour or a whole day, this site might be (eventually!) just the thing for you.

    • Create Podcasts and Improve Coding Techniques

      At the time of writing, is the work of one person. For several months, Jon "The Nice Guy" Spriggs had been considering starting a podcast, however, he's not exactly known for finishing projects! By making a system which is automated enough to create a daily podcast, a weekly podcast and a monthly podcast, playing music that he likes to hear, he thought it might encourage him to stick to it - especially when there are other amazing goals (see above) which come out as a side benefit. He normally has described himself as a writer of "bad PHP code", and each project he starts improves the techniques he has learned.

      In this instance, has introduced Jon to the concept of writing an API that works, a system of remote execution of code, the generation of synthesized speech and the generation of an audio track, entirely in code! Never being shy of criticism from the community, especially where code is concerned, the code has all been released under a license which encourages reuse and requires the code is re-released under the same license.

    If you already podcast, and you play Creative Commons Licesed Music on a regular basis, you might be interested in using the API on this site to track the music that people who listen to your show have expressed an interest in. Contact to find out more

    hpr0746 :: Interview with Tony Whitmore about OggCamp11

    Released on 2011-06-13 under a CC-BY-NC-SA license.

    In todays episode Ken interviews Tony Whitmore of the Ubuntu-UK Podcastabout OggCamp11.

    OggCamp 11 is a two-day technology festival bringing together the most interesting people from the Linux, Open Source and Hardware Hacking communities to share their passion and knowledge on all things geeky in a barcamp-style atmosphere.

    Taking place AUGUST 13 & 14, FARNHAM MALTINGS, UK

    OggCamp 11 is a two-day unconference where technology enthusiasts come together to exchange knowledge on a wide range of topics from Linux and open source software to building home automation systems. Now in its third year, the event is steadily growing and attracting interesting speakers from all over the UK, the rest of Europe and even the US. Since OggCamp is an unconference, speaking schedules are set on the first day and everyone is free to propose a talk themselves. You are of course free to come along and just listen to other people's talks but we strongly encourage everyone to take part and talk on something they are passionate about in technology. OggCamp was first organised by the combined forces of the Linux Outlaws and the Ubuntu UK Podcast as a filler event after the last LugRadio Live was decided to be a one-day only event.

    For the latest news, follow OggCamp 11 on the microblogging service of your choice: / Twitter

    If you are interested in joining the OggCamp crew or sponsoring the event then please email oggcamp at ubuntu dash uk dot org.

    hpr0648 :: Wput: a command-line ftp-client

    Released on 2011-01-26 under a CC-BY-NC-SA license.

    Wput is a command-line ftp-client that looks like wget but instead of downloading, uploads files or whole directories to remote ftp-servers.

    Main Features

    • wget-like interface
    • TLS-encryption
    • resuming
    • speed-limit
    • time-stamping (compares local and remote dates)
    • proxy-support (socks5, http)
    • i18n
    • windows-compatibility

    Wput is a free utility that is able to upload files to a ftp-server.

    Wput is non−interactive and background-capable. It can upload files or whole directories and is meant to be a robust client even for unstable connections and will therefore retry to upload a file, if the connection broke.

    Wput supports resuming, so it automatically continues uploading from the point where the previous upload stopped, meaning that you can kill Wput anytime and it will (if the remote ftp−server supports this, being most likely the case) finish the partial uploaded file.

    Wput supports connections through proxies, allowing you to use it in an environment that can access the internet only via a proxy or to provide anonymity by hiding your ip−address to the server. For SOCKSv5−proxies Wput supports also listening mode, allowing you to use port-mode ftp through a proxy (useful if the remote ftp is behind a firewall or a gateway).

    Wput supports timestamping, so it will (in the ideal case and if timestamping is enabled) only upload files, that are newer than the remote-file.

    The upload-rate of Wput can be restricted, so that Wput won’t eat all available bandwidth.

    hpr0546 :: Shot of Hack – Changing the time offset of a series of photos

    Released on 2010-06-03 under a CC-BY-NC-SA license.
    The problem: You have a series of photos where the time is offset from the correct time but is still correct in relation to each other.
    Here are a few of the times that I’ve needed to do this:
    - Changing the battery on my camera switched to a default date.
    - I wanted to synchronize the time on my camera to a GPS track so the photos matched the timestamped coordinates.
    - At a family event where images from different cameras were added together.
    You can do edit the timestamp using a GUI and many photo manipulation applications like the GIMP support metadata editing. For example on KDE:
        gwenview -> plugins -> images -> metadata -> edit EXIF 
    The problem is that this gets tiresome after a few images, and anyway the times are correct in relation to each other – I just need to add or subtract a time correction to them en masse.
    The answer: exiv2 – Image metadata manipulation tool. It is a program to read and write Exif, IPTC and XMP image metadata and image comments.
    user@pc:~$ exiv2 *.jpg
    File name       : test.jpg

    Exif comment    :
    The trick is to pick a image where you can that figure out what the time was and work out the time offset. In my case I needed to adjust the date forward by six months and four days while changing the time back by seven hours. I used the command exiv2 -O 6 -D 4 -a -7 *.jpg
    -a time
        Time adjustment in the format [-]HH[:MM[:SS]].
        This option is only used with the 'adjust' action. Examples:
            1 adds one hour,
            1:01 adds one hour and one minute,
            -0:00:30 subtracts 30 seconds.
    -Y yrs
        Time adjustment by a positive or negative number of years, for the 'adjust' action.
    -O mon
        Time adjustment by a positive or negative number of months, for the 'adjust' action.
    -D day
        Time adjustment by a positive or negative number of days, for the 'adjust' action.
    When we run this we can see that the timestamp has now changed.
    user@pc:~$ exiv2 *.jpg | grep timestamp
    Image timestamp : 2009:06:11 08:12:59
    That’s it. Remember this is the end of the conversation – to give feedback you can either record a show for the HPR network and email it to or write it on a post-it note and attach it to the windscreen of Dave Yates’s car as he’s recording his next show.
