  • Coracle!

    I’ve been in London for the weekend and one of the joys of visiting is a chance to see my niece Katherine.

    She’s currently in the middle of a project and is building a coracle in her flat in Bermondsey.

    Like other vessels covered by a membrane stretched over a frame, coracles are an ancient form of water craft. The use of coracles in Britain was noted by Julius Caesar on the occasion of his invasion of Britain in 55 BCE.

    The etymology of coracle is from the Welsh corwgl, which is in turn related to Irish curach, meaning a boat.

    Although an ancient form of craft, coracles have still found working uses up to the present day. For instance, for many years until 1979, Shrewsbury coracle maker Fred Davies achieved some notability amongst football fans; he would sit in his coracle during Shrewsbury Town FC home matches at their old riverside ground of Gay Meadow and retrieve stray balls from the River Severn. His coracle was last heard of in the National Football Museum.

    Coracles are difficult to manoeuvre as they are unstable due to their sitting “on” that water. In addition, coracles can easily be carried by currents and the wind. Nevertheless, let’s hope the maiden voyage is recorded for posterity.

  • Bodhi Linux 3.0.0 released

    One of the great things about using a GNU/Linux operating system is that there is generally a purpose-built distribution available should you have specific needs.

    One such specific need is a lightweight operating system for older hardware and a great distribution for using on such machines is Bodhi Linux, which has announced the release of version 3.0.0.

    Minimum system requirements for running Bodhi Linux 3.0.0 are:

    • 1.0GHz processor;
    • 256MB of RAM;
    • 4GB of drive space.

    However, the following are recommended:

    • 1GB of RAM;
    • 10GB of drive space;
    • OpenGL enabled graphics card.

    Bodhi Linux is a lightweight distribution based on Ubuntu (the new release is based upon Ubuntu 14.04 LTS. Ed.) that uses the Enlightenment window manager. The distribution’s philosophy is to provide a minimal base system that users can populate with the software they want. Thus, by default it only includes software that essential to most Linux users, including a file browsers, a web browser and a terminal emulator. It avoids software or features that its developers deem unnecessary.

  • Free software is my Valentine

    Today is 14th February. Most people know this as Saint Valentine’s Day, when florists are overworked and restaurants overcharge. 😉

    However, every year 14th February is also I Love Free Software Day.

    It’s the day when free software users are encouraged to say thank you to the people that produce the great software that millions of people and businesses use and rely upon every other day of the year.

    Do you love free software too? Show it!

    I’d therefore like to express my love for free software and say thank you to:

    Along with the rest of the world, I’m indebted to you all.

    If you use free software too, support this annual campaign, which can be followed on social media with the #ilovefs hashtag.

  • We’re European Green Capital, let’s fell some trees

    It’s only February and Bristol’s year as European Green Capital is already deeply mired in controversy and hypocrisy.

    While the city’s great and good gush praise for an art installation shrouding Pero’s Bridge in fog, ostensibly to draw attention to climate change (how wreathing a bridge heavily used by pedestrians and cyclists does that, I fail to see. Ed.), habitat destruction is happening in parts of the city well removed from rarefied confines in which city elite’s generally move.

    Firstly, there’s the destruction of mature trees in Stapleton that’ll be taking place as part of the Metrobus project – a £100 mn. white elephant of a scheme that’ll knock a mere three and a half minutes off the journey time across the city (according to p.85 of Appendix 6 of the Metrobus Planning Statement. Ed.). The trees will be felled as soon as the protesters currently occupying them are finally evicted by the council’s bailiffs.

    Allied to the Metrobus project, there’s the South Bristol Link Road project. This will result in a loss of environmental amenity for many south Bristol residents in its path. It was announced today that work on this £44 mn. act of environmental vandalism will start at Easter. Presumably more trees will be felled in the process.

    Finally, work has started in the Easton area of the city alongside Easton Way to put in a new cycle facility alongside the dual carriageway. Below is a photograph of the progress of these works to date.

    earthworks at Easton Way Bristol

    At this point an explanation of what can – and cannot – be seen is advisable.

    The works are to provide a new cycle route alongside the dual carriageway.

    The digger is sitting atop the remains of a berm originally built to provide a noise barrier to the maisonettes alongside the dual carriageway.

    Over the years the berm had become covered with mature London plane trees and scrub, providing some much-needed inner city greenery and a valuable habitat for urban wildlife.

    Both the trees and the berm are being removed to provide the above-mentioned cycle facility.

    Being a local, I’m surprised the council has not simply adapted the footpath running alongside the foot of the now vanished berm to shared use.

    That would have been the simplest and least destructive option.

    I can imagine the dialogue down at the Counts Louse City Hall: “What do a few trees and a bit of scrub matter in the inner city? Nobody will notice!” “After all, it is for a cycle facility, so that makes everything all right!”

    As this year’s European Green Capital, doesn’t Bristol City Council’s putting the environment at the bottom of its list of priorities positively reek of greenwash?

  • After the book and film, the HTML colo(u)r chart

    There’s been a lot of interest in the media in recent days over the impending release of the film of E.L. James’ 2011 erotic novel Fifty Shades of Grey.

    Following hard on the heels of the media interest, comes the HTML colo(u)r* chart.

    If you need to pick colours for web pages, fonts and the like, the W3C has a handy picker.

    * In HTML American spellings – e.g. color, center – are used.

  • France: internet connection available on trains by end of 2016

    Libération reports that the entire French railway network will be connected to the internet between now and the end of 2016, according to French train operator SNCF, alluding to forthcoming works to be conducted with mobile operators and Arcep, the French telecommunications regulator. “We shall work in full cooperation with the operators and what we can say, without making a false promise, is that all French trains will without a shadow of a doubt be able to receive the internet properly between and the end of 2016, ” SNCF chairman Guillaume Pepy stated at the end of a press conference.

    “The first stage is to carry out a proper diagnosis with Arcep and a technical diagnosis of the quality of reception on the network with specially equipped trains and a methodology that will be foolproof,” Pepy added. He stressed that there will then be a need to deal with notspots or areas of poor reception and then get round the table. “We are starting these measurements from March onwards so as to be able to share the initial results of these measurements in April with the four [mobile] operators and Arcep,” explained SNCF’s Digital and Communications Director Yves Tyrode.

    SNCF is going “to facilitate infrastructure access to mobile operators for deployment of their antennas,” he added. “As an addition to this 3G and 4G coverage, SNCF is going to increase wifi coverage, but only in certain specific instances, such as some stations and on TGV trains,” he continued.

    An invitation to tender is underway to equip TGV trains with internet access (posts passim), whose outcome will be known at the end of June. “We’re going to change technology. Up to now we tested technology which brought wifi and connection by satellite together and we’re going to change to a technology that will ally wifi on the trains with 4G,” he stressed. “The choice made five years ago and which was hailed by everyone, the satellite-based model, did not prove to be pertinent, neither from a technical point of view, nor a commercial one,” Guillaume Pepy commented.

  • Students discover nearly 40,000 insecure databases

    Cyber security students at Saarland Univeristy in Germany (which I attended during 1975 and 1976. Ed.) have discovered up to 40,000 insecure databases on the internet, the university reports.

    Anyone could retrieve or even amend several million customer accounts with name, address, email and credit card details via the internet, according to information from the University’s Center for IT-Security, Privacy, and Accountability (CISPA). The cause is a wrongly configured, freely available database on which millions of online shops and platforms around the world are establishing their services. If the operators blindly stick to the defaults in the installation process and do not consider crucial details, the data is available online, completely unprotected. CISPA has already contacted the vendor and data protection authorities.

    “It is not a complex bug, but it’s effect is disastrous”, explains Michael Backes, professor of information security and cryptography at Saarland University and director of CISPA. He was contacted by the students and CISPA employees Kai Greshake, Eric Petryka and Jens Heyens at the end of January. Heyens is a cyber security student at Saarland University and his two fellow students plan to concentrate in this subject in the forthcoming semester. The flaw which they detected affects 39,890 databases. “The databases are accessible online without being protected by any defensive mechanism. You even have the permissions to update and change data. Hence we assume hat the databases were not left open on purpose”, Backes explains. The vendor of the database is MongoDB Inc. Its MongoDB database is one of the most widely used open source databases. Out of curiosity, the students queried a publicly accessible search engine for servers and services connected to the internet and thus discovered the IP addresses companies use to run unprotected MongoDB databases.

    When the students called up the detected MongoDB databases with the respective IP addresses, they were surprised. Access was neither locked, nor protected in any other way. “A database unprotected like this is similar to a public library with a wide open entrance door and without any librarian. Everybody can enter”, explains Backes. Within a few minutes, the students also detected this critical condition in numerous other databases as well. They even found a customer database possibly belonging French ISP and mobile phone provider containing the addresses and telephone numbers of roughly 8 million French customers. According to the students, they also found the data of half a million German clients among those addresses. Another unprotected database detected was that of a German online retailer which included payment information. “The saved data can be used later to steal identities. Even if the identity theft is known, even years later the affected people have to deal with contracts signed under their own names by the identity thieves”, says Backes. The CISPA researchers began contacting MongoDB Inc. immediately, as well as the international computer emergency response teams (CERTs). They informed the French data protection service, the Commission nationale de l’informatique et des libertés, and the German Office for Information Security. “We do also hope that the developer of MongoDB will quickly include our results, incorporate them into its guidelines and forward them to the companies using the database”, says Backes.

    CISPA has released a report of its findings (pdf).

  • Mama

    The video below features very first performance of ‘Mama’, which was composed by the youth campaigners of Integrate Bristol, a local charity formed to help with the integration of young people and children who have arrived from other countries and cultures.

    Integrate Bristol is also active combating violence against women and girls; this includes the fight against female genital mutilation (FGM).

    ‘Mama’ was written in honour of Efua Dorkenoo, also known as Efua Mama, the ‘mother’ of the movement to end FGM.

  • Another sign of spring

    Following on from last weekend’s catkins (posts passim), another sign of spring has just emerged: the croci (or crocuses) have burst into flower in the pocket park in Chaplin Road, Easton. On a bright, sunny day the flowers shine like beacons.

    crocus in flower

    Although not native to the British Isles, crocus sativus, the saffron crocus, has long been cultivated for the spice saffron.

    Indeed, such cultivation has given rise to some place names. For starters, there’s Saffron Walden in Essex, as well as Croydon in the sprawl of Greater London.

    As regards the latter, the theory accepted by most philologists is that the name Croydon derives originally from the Anglo-Saxon croh, meaning “crocus”, and denu, “valley”, indicating that it was a centre for the cultivation of saffron. It has been argued that this cultivation is likely to have taken place in the Roman period, when the saffron crocus would have been grown to supply the London market, most probably for medicinal purposes, and particularly for the treatment of granulation of the eyelids.

    The croci shown above are not saffron crocus, but are still a welcome sight. On a sunny day the air inside the flower cup of the crocus is said to be some degrees warmer than the surrounding air, making it a welcome place to visit for early pollinating insects.
