Launch your own craft into space

There’s nothing like home-made science, and the video below shows just that taken to an incredibly impressive degree. Luke Geissbuhler and his family and friends spent eight months testing a ‘space capsule’ made up of a foam container, video camera and an iPhone.

The results are amazing – and it was educational to boot for all involved. It’s obviously not a low-budget home project but it’s certainly one that delivered some great results. It sort of beats playing Wii Sports as a family!

Why Second Life is already second-best for education

The announcement by Linden Lab in the past 24 hours that their discounting of pricing for educators and non-profits would cease in January 2011, has engendered the expected level of outrage. And rightly so, given the critical mass of educators that have generated significant outcomes for Second Life. In fact, it could be argued that it’s only the good news stories generated by the non-profits that have helped offset some of the negative aspects inflated by parts of the mainstream media and others. The comments section below the announcement is well worth a read: even taking out the initial emotion, the overwhelming attitude is that it’s time to downsize or move on. Of course, the migration to OpenSim grids is already well underway, for a range of reasons.

As someone who follows virtual worlds pretty closely, I thought I understood the specific reasons for the move from Second Life fairly well. However, I only got the full picture over the past month, when I needed to explore options for my own education-related build. Without boring you with detail, I’m looking at conducting some research that will involve some fairly complex simulations. When I wrote the proposal for the research, I was already assuming that Second Life wouldn’t necessarily be the platform due to cost constraints (and this was before the price-rise announcement). That assumption was confirmed after some detailed discussions with a number of people, including someone developing a number of education-related projects including one aligned with my own proposal.

Based on those discussions and my own observations, here’s the key reasons I’ll not be working in Second Life for my education project (and most likely using either Unity3D, OpenSim or both):

Content creation: Although SL provides some great scripting options, the learning curve is significant and there’s minimal support for defacto design and modelling platforms. This leads to the need to either hire an SL builder or give up a significant chunk of time to learn a scripting language that’s not transferable elsewhere (except in some respects to OpenSim).

Structured learning: There is minimal ability in SL to guide avatars through particular experiences. Heads-up displays can work to some extent, but the scene-by-scene capability of Unity3D is head and shoulders above.

Reliability: ignoring historical challenges, the fact remains that down-time in SL is totally at the mercy of Linden Lab. A standalone OpenSim grid or a Unity3D installation aren’t as susceptible.

Client: SL being still being a standalone client makes it a bigger challenge to use for education that a web-based client. That may change in the medium-term but it’s a deal-breaker for purposes where dedicated PCs aren’t an option.

Ease of use: One of the key weaknesses of SL is it’s ease of use, particularly for new users. It’s something that has improved and will continue to improve. Although competitors aren’t markedly better, they certainly aren’t worse.

I want to make an important point: Second Life deserves to continue to grow and I’m still confident it will, albeit with a very different focus to what it has now. The decision on education pricing fits the wider business model as it now stands. Even that is fine, if it’s based on confidence of a new market and unshakeable faith that the current shortcomings of SL will be overcome soon enough. On the face of it, that market isn’t apparent and the improvements still seem a while away.

I’d love to hear from educators / non-profits at the coalface. Emotions aside – have you started considering moving away from Second Life, and if so why?

Update: Linden Lab have made a follow-up statement with a rather interesting take on things.

Homeless under pressure: YouTube style

Homelessness is a worldwide issue that has arguably gotten worse in developed nations since the global financial crisis. There’s no shortage of stereotypes around homelessness, including the image of the beggar on the street with a sign asking for money. Like most stereotypes, they’re at least partially based on fact.

In the video below, a person claiming to be homeless is begging for money. He’s also providing some amazing entertainment to the words and music of Under Pressure by Queen and David Bowie.

Have a look:

I’ve attempted to get more background on the video but am unable to find any. As someone’s said in the comments, it’d be great if you could donate money to support people in these situations. There’s an obvious non-profit business model there for the right entrepreneur: a crowdsourced capture of individual homeless people and the situations they face, with the ability to sponsor / donate. Kiva does it perfectly in developing nations and there are plenty of other micro-finance options around. This is different though – this is about that initial helping hand where a person has nothing but two Kermit puppets to make a living.

What do you think? Also – we’ll add a donation link if the background to the video is ever disclosed. This is one that deserves to go viral.

UPDATE: the person who created the video has now provided some info:

This is a performance meant to entertain and inspire.

If you want to help…

As I said this is a performance. I don’t want there to be any doubts about my situation. I am a performer. I have a roof over my head and I have yet to start my own family. But this video isn’t about me. This is for the men, women and children on our streets who don’t have bright green puppets on their hands. The people who aren’t always as easy to see. This is for you.

Is Linden Lab up to the job of keeping younger teens safe in Second Life?

In some ways the decisions surrounding Linden Lab’s closure of Teen Second Life, and the plans for its teen users represent an almost perfect microcosm of Linden Lab process.

There’s the decision to close Teen Second Life, apparently made without consulting with … well, anybody at all. As a part of this, older teens (16-17 years old) will be migrated to the adult grid along with their elders, but under some restrictions that remain a secret at present, despite now being just a few weeks away.

There’s the much better decision to allow younger teens (13-15) to be allowed a form of restricted access to Second Life, in order for a number of worthy education, community and support programmes to continue. A decision which appears to have been grudgingly granted at the behest of programme providers, and which doubtless would have surfaced originally, if they had only been consulted.

Now it remains to be seen if Linden Lab can carry this off. A mix of teens and adults in Second Life can be a potentially volatile mix from a public-relations and media perspective. Reducing the risk of potential scandal will require the utmost care and attention-to-detail from Linden Lab as they prepare to migrate users.

Fortunately, most of the code required for younger teen users appears to already be a part of the grid systems, and has been mostly successful at keeping Teen Second Life and Second Life largely isolated from each-other so far. There’s certainly some expressing doubts that Linden Lab will be able to competently meet the challenge, as many feel that those levels of care and quality-assurance exceed the organisation’s capabilities.

The plan with younger teens is to restrict them to the estates of a sponsoring organisation or programme. Each of the younger 13-15yo teens will be signed on with a particular group, and allowed no access beyond that group. Adult members of the organisation will keep estate-controls tight, allowing only approved and authorised adults access. Additionally, younger teen accounts would not have access to the new Second Life marketplace on the Web.

Now, that’s good, but clearly it isn’t enough. Teens in Teen Second Life have thus far had much greater protections than this, being protected from messaging by adult accounts who weren’t currently logged into the teen estate (a very limited privilege), and unable to be sent content by adult accounts from outside of the teen estate.

Under the new system, adult accounts in the sponsoring group would clearly be able to bring content into the sponsoring estate from the broader grid of Second Life, or (while in the estate) give content to or instant-message a younger-teen account in their sponsored group. These are fine. What about instant-messages or inventory transfers from adult accounts outside of the sponsored estate, however?

If those were to be permitted, any teen could be sent prurient account or sexually harassed by any adult or prankster with a throwaway account who wished to do so. That’s a media scandal in the making right there, and there’s certainly a minority of people in the world who would choose just such tactics to cause one.

As I said, of course, the code exists now to prevent this inappropriate crossing of estate boundaries with respect to contact with younger-teens, if it is appropriately planned, carefully adapted and diligently tested, and if Linden Lab has even thought to do so.

The question is, is Linden Lab up to the job of keeping younger teens safe in Second Life?

Update (Lowell): On top of the Teen grid decision, Linden Lab have now announced a cessation of discounted pricing for educators purchasing full regions on the main grid. It’s hard to see a result other than less nuanced education projects as pricing forces them to Homestead and Open Space regions. More on this later.

Death, obituaries and website comments

This article in the St Petersburg Times, a Florida USA paper, is the sort of one that can make you very angry and bring a tear to the eye, all within a few paragraphs.

The synopsis: a man who worked as a dish washer for $9 an hour died as a result of a hit-and-run accident, when the announcement of his death occurred a reader posted ‘A man who is working as a dishwasher at the Crab Shack at the age of 48 is surely better off dead’. The response from other readers, the man’s friends and work colleagues and the newspaper show that there’s still plenty of community left. Journalist Andrew Meacham and his editor deserve huge kudos for follwing up with a superb story.

On the tech side, comment moderation is an old chestnut, and the idiot that posted the comment won’t be the last. The challenger for the future is that as mainstream media outlets get less influential and news sources diversify further, who will be the arbiter of community standards? If the same comment had appeared on a blog or social media service, the response to it might have been different. That’s not an argument for the status quo, but a prompt for discussion on an issue that’s not going to go away.

What do you think: will there ever be a solution to the idiot troll?

Sick of loud TV ads? So are politicians

It has sometimes been described as a myth, but most of us will have experienced the jump in volume when a TV show segues to an advertisement. I don’t know anyone who sees the phenomenon as a positive one, and in the US at least, politicians have picked up on the mood of voters. The US Senate has passed a bill mandating compulsory equalisation of sound between TV shows and ads. It’s expected that after some tweaking in conjunction with Congress, who have passed a similar bill, the law will come into effect after the November mid-term elections.

Is there anyone out there that will miss louder ads? Will the ‘Dave’s Demented Discount Den’ 30-second TV spots sound as endearing at lower volume?

Diabetes, Second Life and health outcomes

This story appeared over at Metaverse Health originally.

The Boston University Medical Center continues its work on health and virtual worlds, succeeding in gaining a US$950,000 grant from the US National Library of Medicine. The funding is for a study on the efficacy of using Second Life for Type 2 Diabetes education with African-American women versus more traditional face-to-face interventions.

You can read more detail on the study here, but there’s one key strength of the study that stands out for me: quantitative health data. Each participant will have cholesterol and ‘diabetes control’ blood tests taken before and after they receive the education sessions, as well as blood pressure readings.

The results of the study are likely to be be groundbreaking: either virtual worlds-based interventions for diabetes will be shown to be effective, or a very large challenge will be laid down to virtual worlds advocates if the results aren’t of the quantum expected. This is a study to watch.

Mashups: some of the best

One of the reasons I keep going back to YouTube is to see great mashups. As a musician / tech-head myself, I know how much work must go into each mashup on the audio side, let alone when you add video to the equation.

Tom Compagnoni has been creating mashups since 2003 and it shows. This year he’s released three gems, which you can see below. Mashups are an artform that excels when it is both seamless and striking in the contrast of songs, and Tom’s work on the three below, achieves those aims with flying colours. If you’re interested in how he does what he does, you can find out more here.

Here they are in no particular order (I’ve got to admit Thunder Busters is my favourite):

1. Whole Lotta Sabbath (Led Zeppelin vs Black Sabbath Mashup)

2. Thunder Busters (AC/DC vs Ghostbusters Mashup)

3. PJ Harvey, Tori Amos, Björk & Massive Attack Mashup

Would love to hear your favourite mashups – post away in the comments! No Rickrolling or Trololololing please 😉

Games are cool for school

You may have heard of the term Serious Games before: essentially they’re games with a purpose beyond entertainment. There’s a growing awareness that games can be used for wider purposes such as business productivity, health support and for education. It’s that last point I’ll focus on here.

Arizona University’s James Paul Gee has completed a brilliant piece on the usefulness of games in education, which you can view below. The key point is that games are one ongoing test, like school, and there’s a bunch of good reasons why combining the two can be incredibly useful for educators.

Sceptical? You may be less so after hearing the case for serious games:

Over to you: would you like to see more games-based education in schools? If not, why not?

Texting while driving: now a proven deadly habit

Photo courtesy http://texting-while-driving.org/

A study by the University of North Texas Health Center has shown what may be unsurprising to a lot of people: texting while driving has killed a lot of people.

The study looked at United States drivers between 1999 and 2008, and amongst other things found:

  • After declining from 1999 to 2005, fatalities from distracted driving increased 28% after 2005, rising from 4572 fatalities to 5870 in 2008
  • Crashes increasingly involved male drivers driving alone in collisions with roadside obstructions in urban areas.
  • Increasing texting volumes resulted in more than 16000 additional road fatalities from 2001 to 2007.

Of course, the challenge will be somehow convincing the huge number of driving texters out there that they in fact aren’t better drivers than the sixteen thousand people who have died already. There are already sites devoted to the issue, such as this one.

It’d be interesting to know what the gender breakdown of the fatalities were i.e. are males the primary offenders like they are with accidents more widely? Or is it something that females dominate?

Would love to get your thoughts / close call stories.
