  • Ubuntu takes to the air

    The world’s first drone powered by the Ubuntu Linux distribution has arrived, Softpedia reports.

    Erle Robotics, a Spanish company known for all types of robots powered by Linux, launched the world’s first Ubuntu-powered drone on 3rd May.

    The Erle-Copter has a flight time of some 20 minutes and can handle a payload of 2 kg.

    As regards price, the Erle-Copter Ubuntu Core special edition drone costs €399 for the very basic version, which won’t fly. If you want to buy an Erle-Copter that flies and has the basic components, you will have to pay at least €574.

    “Erle-Copter Ubuntu Core special edition drone is a Ubuntu-powered quadcopter that includes official support for new app store for drones and robots. It has official ROS support, capable of the different flight modes and [is] ideal for outdoor operations,” says Erle Robotics’ Alejandro Hernández.

    The version of Ubuntu used by the Erle-Copter is Snappy Ubuntu Core, a new version of Ubuntu for clouds and devices comprising a minimal server image with the same libraries as the conventional Ubuntu distribution, but applications are provided through a simpler mechanism.

  • Openwords on Kickstarter

    Openwords, the foreign language learning app for the world’s open language data the world’s under-served languages, which was reported on some weeks ago by this blog (posts passim), recently launched a crowdfunding campaign on Kickstarter.

    At the time of writing the Kickstarter campaign has 16 days to go and aims to raise $10,000 to take the project to the next stage.

    Foreign language learning with open data

    There are millions of people around the world who can’t learn the languages in which they’re interested.

    While the learning of major languages like Chinese, Spanish and French are supported by large companies, these firms tend to ignore lesser-known languages.

    Openwords is doing things differently to solve this problem. Openwords is mining data from the public domain assets like the Wiktionary to provide educational content for all the languages, large and small.

    So far Openwords has mined data for 1,000 languages.

    The Openwords app has various learning modules for vocabulary, hearing, typing, amongst others. In addition, the Openwords developers are working on simple sentence translation problems. Furthermore, learners have control over the content they want to learn.

    Openwords on mobile phone

    Finally, Openwords will be an open source project.

    The aim of the Kickstarter campaign is to raise $10,000, which will be enough to develop a beta model of the Openwords app.

  • Research shows language you speak changes your view of the world

    In research that was published recently in Psychological Science, German-English bilinguals and German and English monoglots were studied to find out how different language patterns affected how they reacted in experiments.

    This research shows that bilinguals can also view the world in different ways depending on the specific language in which they are operating, according to Mashable.

    The past 15 years have seen extensive research on the bilingual mind, with most of the evidence pointing to the tangible advantages of being bilingual. Going back and forth between languages appears to be a kind of brain training, pushing your brain to be flexible.

    To quote the abstract for the research paper:

    People make sense of objects and events around them by classifying them into identifiable categories. The extent to which language affects this process has been the focus of a long-standing debate: Do different languages cause their speakers to behave differently? Here, we show that fluent German-English bilinguals categorize motion events according to the grammatical constraints of the language in which they operate. First, as predicted from cross-linguistic differences in motion encoding, bilingual participants functioning in a German testing context prefer to match events on the basis of motion completion to a greater extent than do bilingual participants in an English context. Second, when bilingual participants experience verbal interference in English, their categorization behavior is congruent with that predicted for German; when bilingual participants experience verbal interference in German, their categorization becomes congruent with that predicted for English. These findings show that language effects on cognition are context-bound and transient, revealing unprecedented levels of malleability in human cognition.

    By way of illustrating these differences, Mashable’s piece gives a handy example of these different world views

    German-English bilinguals were shown video clips of events with a motion in them, such as a woman walking towards a car or a man cycling towards the supermarket. The participants were then asked to describe the scenes.

    When such a scene is presented to a monoglot German speaker they will tend to describe the action and the goal of the action. Thus they would tend to say “A woman walks towards her car” or “a man cycles towards the supermarket”. English monoglot speakers would simply describe those scenes as “A woman is walking” or “a man is cycling”, without mentioning the goal of the action.

    As regards the effect of the language being spoken on bilingual speakers’ perceptions of the world, they seemed to switch between these perspectives based on the language in which they were given the task. Germans fluent in English were just as goal-focused as any other native speaker when tested in German in their home country. However, a similar group of German-English bilinguals tested in English in the UK were just as action-focused as native English speakers.

  • A chance meeting

    Walking down Stapleton Road this morning, I stopped to take the picture below in readiness for reporting the fly-tipping to Bristol City Council.

    fly-tipping outside 96 Stapleton Road

    The gentleman passing on the right of the picture and half caught by the camera saw what I was doing, thanked me effusively and shook my hand when I told him I was reporting it to the council.

    We then had a brief conversation about how such anti-social behaviour detracted from the pleasantness of Bristol, which he described as a “beautiful city”, the health implications of fly-tipping and the way they encouraged the spread of vermin such as rats (posts passim).

    As we parted with waves, he asked me whether I was a member of the Green Party. Unfortunately I have no affiliation, but that’s no barrier to being an active and caring citizen.

  • Sexism in cafĂ© society

    An unnamed café in Bristol is apparently serving his and hers breakfasts.

    café menu board featuring his and hers breakfasts

    Yes, that’s right! Men get to scoff tortilla, bacon, sausages, 2 token items of fruit/vegetables (tomato and mushroom), Cheddar cheese, ham roll and butter, whilst women are supposed to pick their way daintily through muffin, poached egg, smoked salmon, salad leaves, cherry tomatoes, avocado, red onion, blueberries, yoghurt and pumpkin seeds.

    Men can obviously let their figures go to pot (and blood cholesterol levels too. Ed.), whilst women are automatically assumed to be on a diet; women have “gotta stay slim for our men obvz” in the scathing words of one on social media.

    This isn’t the first time that sexism has emerged at breakfast time (posts passim).

    Update 30/04/15: The his and hers labels are being removed from the menu according to the Western Daily Press, which also revealed the name of the establishment as Caffe Be On. In addition, this post was quoted in yesterday’s Daily Mirror.

  • Debian 8 released

    Debian logoYesterday Debian announced the release of Debian 8, codenamed ‘Jessie’ as the latest stable release of this popular GNU/Linux distribution.

    The release will receive support and updates for the next 5 years and has been in development for the last 24 months.

    “Jessie” ships with a new default init system, systemd. The systemd suite provides many exciting features such as faster boot times, cgroups for services, and the possibility of isolating part of the services. The sysvinit init system is still available in “Jessie”.

    The UEFI (“Unified Extensible Firmware Interface”) support introduced in the previous stable release (“Wheezy”) has also been greatly improved in Jessie. This includes workarounds for many known firmware bugs, support for UEFI on 32-bit systems, and support for 64-bit kernels with 32-bit UEFI firmware (with the latter being included only on Debian’s amd64/i386 “multi-arch” installation media).

    It’s not just the Debian project’s developers that have been working hard for the release of “Jessie”. Thanks to the huge efforts of translators working on localisation, Debian can now be installed in 75 languages.

    Trying Jessie

    If you want to try Debian 8 “Jessie” without having to install it, you can use a special image, known as a live image, available for CDs, USB sticks, and network booting set-ups. For the time being, these images are provided for the amd64 and i386 architectures only. It is also possible to use these live images to install Debian. More information is available on the Debian Live homepage.

    Upgrading

    Those wishing to upgrade to Debian 8 from a previous version, such as Debian 7 “Wheezy”, are strongly advised to read the release notes as well as the installation guide for possible issues, plus detailed instructions on installing and upgrading.

    Your correspondent has been using “Jessie” on a 5 year-old laptop for the last year (posts passim), i.e from about halfway through its time as Debian’s testing stable version and has found it to be fast, stable and reliable.

    In other Debian news, the first release of the new version of Debian Edu, the special education-related distribution, based on Debian 8 “Jessie” is now in beta.

  • Post exclusive: Bristol Rovers change kit

    There’s a hidden exclusive in today’s online edition of the Bristol Post. Unknown to the fans and probably the club itself, the Post reveals that Bristol Rovers now play in “blue and white stripes“, as shown by the following screenshot.

    screenshot featuring text But it turned out to be Sabadell fans, who were decked out in their home kit, which looks similar to the Rovers's blue and white stripes

    For the benefit of passing Post journalists, here are the three strips currently used by Bristol Rovers. Please note the only stripes are on the alternative away colours and have one thin blue stripe. The pattern used on the regular strip is commonly known as “quarters“.

    The Post also mentions in the article that Catalonia’s CE Sabadell FC (who are in the Spanish Segunda DivisiĂłn. Ed.) play in a strip “similar” to that of Rovers. FC Sabadell’s current strips are shown below and yes, the home strips do look very similar, even if the teams’ respective league positions do not; Rovers are chasing promotion from the Conference, whilst Sabadell are fighting relegation.

    Let’s hope the players of both teams are more on target than Bristol’s alleged newspaper of record. 🙂

  • Stretch: the next Debian testing stable version

    Debian logoWith Debian 8, codenamed ‘jessie’, currently frozen and due for release as the next stable release at the end of April (posts passim), many may have been wondering what the next Debian testing stable release will be.

    However, this particular question has now been answered. Writing on reddit, user dimitrifromparis has revealed the next character from the Toy Story series of films to be used as a Debian release codename.

    After the jessie release, there will be a new release codename, “stretch”, and testing will be an alias for that.

    See the Debian wiki for an overview of past Debian production release codenames.

    Besides testing stable, Debian also has a testing unstable version, named sid. Sid is never released as such and is named after Sidney, the boy next door in Toy Story who always broke his toys. Needless to say, Debian sid is definitely not recommended for production environments.
