Wifi from wee

12/12/2015 Steve WoodsBristol, Oddities, Tech

Bristol boffins have developed a pair of socks embedded with miniaturised microbial fuel cells (MFCs) and fuelled with urine pumped by the wearer’s footsteps that have powered a wireless transmitter to send a signal to a PC. This is the first self-sufficient system powered by a wearable energy generator based on microbial fuel cell technology, the University of the West of England (UWE) reports.

Microbial fuel cell socks

This world first feat is described in the scientific paper, ‘Self-sufficient Wireless Transmitter Powered by Foot-pumped Urine Operating Wearable MFC’ published in Bioinspiration and Biomimetics.

How the set-up works

This paper describes a lab-based experiment led by Professor Ioannis Ieropoulos, of the Bristol BioEnergy Centre at the UWE. The Bristol BioEnergy Centre is based in Bristol Robotics Laboratory (BRL), a collaborative partnership between the UWE and the University of Bristol.

Soft MFCs embedded within a pair of socks were supplied with fresh urine, which was then circulated by the human operator walking. Normally, continuous-flow MFCs would rely on a mains powered pump to circulate the urine over the microbial fuel cells, but this experiment relied solely on human activity. The manual pump was based on a simple fish circulatory system and the action of walking caused the urine to pass over the MFCs and generate energy. Soft tubes, placed under the heels, ensured frequent fluid push–pull by walking. The wearable MFC system successfully ran a wireless transmission board, which was able to send a message every two minutes to the PC-controlled receiver module.

Professor Ieropoulos says, “Having already powered a mobile phone with MFCs using urine as fuel, we wanted to see if we could replicate this success in wearable technology. We also wanted the system to be entirely self-sufficient, running only on human power – using urine as fuel and the action of the foot as the pump.”

“This work opens up possibilities of using waste for powering portable and wearable electronics. For example, recent research shows it should be possible to develop a system based on wearable MFC technology to transmit a person’s coordinates in an emergency situation. At the same time this would indicate proof of life since the device will only work if the operator’s urine fuels the MFCs.”

MFCs use bacteria to generate electricity from waste fluids. They tap into the biochemical energy used for microbial growth and convert it directly into electricity. This technology can use any form of organic waste and turn it into useful energy without reliance on fossil fuels, making this a valuable green technology.

The Document Foundation recommends the deployment of LibreOffice in enterprises and large organisations with the backing of certified professional support.

LibreOffice 4.4.7 is available for download from http://www.libreoffice.org/download/libreoffice-still/.

The next release of the more cutting edge LibreOffice 5.x series will take place early in 2016.
The Document Foundation seeks boost to LibreOffice developer numbers

25/11/2015 Steve WoodsLinux, Open Source, Open Standards, Tech

The Document Foundation has announced a new drive to increase its developer community beyond the level of 1,000 reached in October 2015.

The growth of the LibreOffice developer community has been extraordinary, with a monthly average of over 16 new hackers contributing to the code since September 2010. This is due in the main to mentoring by the project’s founders. After five years and 1,000 new developers, though, the complexity has changed, and the project needs to invest on mentoring a new generation of coders.

LibreOffice has always been available on multiple operating systems – Linux, Mac OSX and Windows – and is now on the verge of being available on multiple platforms: desktop, mobile and cloud. Consequently, the project needs a wider range of developer skills, which can be achieved only with a renewed effort targeted to attract new contributors.

“When LibreOffice started, the codebase we inherited was known for being extremely hard to contribute to, for both technical reasons and a lack of mentors reaching out to new hackers,” says Bjoern Michaelsen, a member of LibreOffice engineering steering committee and a director of The Document Foundation. “Today, the LibreOffice project is known for its welcoming atmosphere, and for the fun. We strive to continue on this path for the next 1,000 code contributors.”

A World Without Linux – episode 4

23/11/2015 Steve WoodsLinux, Media, Open Source, Tech

The Linux Foundation has released episode 4 of its A World Without Linux video series.

Called “Avatar Reimagined”, this latest video sees characters Sam and Annie going to the pictures (as we used to call them when I was a lad. Ed.) to watch a film with really bad special effects to make the point that the effects in many blockbuster movies are made on Linux supercomputers.

The Linux Foundation commissioned six episodes for the series, leaving one left before the final episode featuring Mr Linux Kernel himself, Linus Torvalds.
Trusty Tahr brought down by cat

16/11/2015 Steve WoodsLinux, Media, Oddities, Open Source, Tech

Linux distribution bug reports are not a place one expects to find stuff to make one smile: they’re normally places where the faults and failings of software are described in normally boring detail.

However, today proved an exception to the rule, courtesy of one filed a short while ago for Ubuntu 14.04 LTS, codenamed “Trusty Tahr“, which has just come to prominence.

14.04, locked screen to go to lunch, upon return from lunch cat was sitting on keyboard, login screen was frozen & unresponsive.

To replicate: In unity hit ctrl-alt-l, place keyboard on chair. Sit on keyboard.

Resolution: Switched to virtual terminal, restarted lightdm, lost all open windows in X session.

What should have happened: lightdm not becoming unresponsive.

Ubuntu fans are now trying to reproduce this bug, including some who want to try and reproduce it with other pets, as per the latest comment on the bug report page reproduced below.

will it also work with a small dog, please some one with a small size dogs test it!

LightDM is the display manager running in Ubuntu. According to the Ubuntu Wiki, it starts the X servers, user sessions and greeter (login screen).

What’s a tahr? Wikipedia informs us that tahrs form a family of three species of large Asian ungulates related to the wild goat. The three species are the Himalayan tahr, Nilgiri tahr and Arabian tahr.

Finally, there are millions of pictures of cats and kittens all over the internet. Indeed, there’s even a Firefox add-on called Kitten Block that steps in whenever the user who has it installed attempts to access the right-wing Daily Mail and Daily Express websites. However, there are far fewer pictures of tahrs. Let’s remedy that with a fine picture of a male Himalayan tahr courtesy of Wikimedia Commons.

“Open source can liberate local authorities being held to ransom,” says Dutch MP

13/11/2015 Steve WoodsOpen Source, Open Standards, Politics, Tech

Open source software is a good option for local authorities who are dissatisfied with the price and quality of their software, says Dutch Labour MP Astrid Oosenbrug. This former sysadmin believes open source and open standards can liberate local authorities from their current suppliers, who she maintains can have too much power over their customers.

Situation “has been going on for years”

It recently became apparent from an investigation by NRC and Reporter Radio that many local authorities feel they are being held hostage by their software suppliers who are making the most of a dysfunctional market with price increases. According to Oosenbrug, the situation “has been going on for years”. She has been campaigning for a long time for open standards and open source solutions, her greatest success being a parliamentary motion passed in April according to which the government would be obliged to give preference to open source in invitations to tender.

More opportunity for open source

From their dissatisfaction, Oosenbrug perceives that local authorities are seeking alternatives to their current software. Oosenbrug states: “The opportunities for open source are increasing and definitely now the government is giving it preference. Amongst local authorities we do find those where the councillors won’t interfere (with procurement choices. Ed.), but I’ve also sat in the council chamber myself. Not every intervention from The Hague is in itself bad or negative, but is on the contrary supportive.

Open source good option for local authorities

In open source software the software’s source code is published and freely available to the public. The software can therefore be freely copied, adapted and distributed. Software standards between applications that work, services, systems and networks that work with each other can be inspected with open standards.”

Oosenbrug views open source and open standards as a good choice for local authorities. “Software companies have a hold on them with their products. If there’s no agreement with price rises, they stop providing the services and local authorities get into quite a bit of trouble. With open source local authorities can be freed from the stranglehold. With open source, anyone can examine the software used and inspect the source code. In this way security holes and clumsy coding are quickly traced.” Users with expertise are also looking everywhere, on account of which the software remains up to date and inexpensive solutions can often be found,” declares Oosenbrug. “There is a safe environment in which ethical hackers for example can play a major role.”

Open standards

Local authority websites are regularly attacked and are sometimes as leaky as a sieve. Consequently, Oosenbrug is also advocating open standards in addition to open source. “Of the 360 local authorities, only thirty comply with accessibility standards. You can overcome these sorts of problems with open source and open standards.” Oosenbrug believes there should be a template for websites with which local authorities can comply with all standards. “The remainder of a website can then be completed according to the local authority’s own preferences.”

Investment repays itself

Open source and open standards mean a considerable investment, but Oosenbrug believes it’s one that is repaid. “The bid that works best wins invitations to tender. Everything is checked for price and quality by the users themselves. Local authorities are currently in the land of the blind where the one-eyed man is king and they must always pay more. Software is becoming safer and cheaper with open source. The government must not view open source as a punishment, but as an opportunity.”

Municipality of Ede

Several local authorities have made progress with open source. In this way the Municipality of Ede has been able to make appreciable savings. After the changeover, it has been spending ten times less for software licences than comparable local authorities. On account of this, total ICT expenditure has been one quarter less than previous years.

Windows NT 3.1 software crash brings Orly airport to standstill

13/11/2015 Steve WoodsOddities, Tech

Last Saturday, Orly airport‘s air traffic was severely disrupted, leaving thousands of passengers stranded on the ground, Le Monde Informatique reports. The cause: a computer failure of the weather data management system running on Microsoft’s antediluvian Windows NT 3.1 operating system.

Computer system failures in the aeronautical world are nothing exceptional, but always have a far-reaching effect, stranding thousands of passengers on the ground. This is exactly what happened last Saturday at Orly which had to halt of all its inbound and outbound air traffic for more than half an hour. Besides the inconvenience caused, it’s above all the origin of the failure that is somewhat surprising. According to the French satirical paper Le Canard Enchaîné, it was a failure linked to the Decor (Diffusion des données d’Environnement de Contrôle d’Orly et de Roissy = Orly & Roissy Environmental Control data distribution) system managing data provided by Météo France that was the culprit.

The surprising fact was this software is running on the Windows NT 3.1 operating system released by Microsoft 22 years ago, i.e. an operating system no longer supported at all by Redmond, with all the risks this involves in security terms, especially as it is connected to Météo France’s computer systems.

“The traffic was not particularly heavy on Saturday morning. But imagine during the Paris Climate Change Conference, the manoeuvring of heads of state disrupted by a piece of software dating from prehistoric times. What will that look like?”, stated an engineer quoted by Le Canard Enchaîné. When contacted by the satirical paper, the Transport Ministry gave an assurance that “equipment modernisation is planned for 2017” (no need to rush, then! Ed.).
A world without Linux – episode 3: no social connections

09/11/2015 Steve WoodsLinux, Media, Open Source, Social Media, Tech

Although you may not realise it, Linux is the world’s largest collaborative project in the history of computing. It runs most of the world’s technology infrastructure and is supported by more developers and companies than any other operating system. In addition, it’s ubiquitous; it can be found in your phone, car and office. Besides that, it also powers the internet, the cloud, stock exchanges, supercomputers, embedded devices and more.

The latest episode of the series tries to show us how hard it is to have social connections is a universe without Linux.

Three more episodes of this Linux Foundation series are planned, with the final video featuring Linux kernel creator Linus Torvalds himself, according to Softpedia.
Turnip tops = clitoris; Google Translate strikes again!

04/11/2015 Steve WoodsLanguage, Media, Oddities, Tech

Today’s Guardian reports that organisers of the “Feira do grelo” food festival in As Pontes in Galicia were shocked when their event celebrating the culinary delights of turnips tops, a traditional staple turned out to be celebrating a rude part of the female anatomy.

To quote The Guardian’s piece:

But for the past few months, the small town was marketing a very different kind of festival after it used Google Translate to put the Galician word grelo into Castilian Spanish, ending up with it inviting people to take part in a “clitoris festival”.

And quoting yet again:

It meant the town’s “Feria [sic] do grelo” or rapini festival – held every February with tastings and awards for the best grelos – became “Feria clítoris” in Spanish.

Clitoris? Yes, according to Google Translate!
Furthermore, The Independent adds that the error was not discovered until Castilian-speaking rapini fans visited the site to read about the upcoming festival and found themselves reading about a local clitoris festival instead of the benefits of the local vegetable.

The humorous consequences were fully reported in The Local.

The Castilian Spanish version of the town council’s website’s content about the festival included such howlers as “The clitoris is one of the typical products of Galician cuisine,” and “Since 1981, the festival has made the clitoris one of the star products of the local gastronomy.”

The reason for this embarrassing howler is that Google Translate mistakes the Galician grelo for the Portuguese word grelo – which is both the word for the vegetable as well archaic slang for clitoris.

“It’s a very serious error on the part of Google and we are thinking about making an official complaint for Google to properly recognise the Galician language so this kind of thing doesn’t happen again,” said town hall spokeswoman Montserrat Garcia.

Along with Spanish, Galician is an official language in Spain’s north-western region of Galicia, where over 2.4 million people speak the regional tongue.
