It’s taken a bit longer than I thought. Here’s our “A”

Simple, isn’t it? It’s one colour – black. What could be simpler?

Well actually it isn’t one colour. it’s 255 shades of gray (I have given up and use US spelling for compsci things). or more correctly it’s a gradation from 0 (black, no light at all) to 255 (as white as you can get). Look closely and you will see “jaggies” which aren’t completely blank. They are there as “antialiasing” – a method to make it look nice for humans (and it works). Remember we aren’t allowed to draw straight lines – we have to use pixels. Many years ago – 1970 – we used pen plotters (Calcomp) or moving spots of light (Tektronix) to draw straight lines. The great Evans and Sutherland computers – for which modern structural biologists should be grateful – produced many of the classic protein structures with straight lines (vectors) during the 1980′s.

But then pixels came back – Silicon Graphics and desktops – and are almost universal. So we have to draw lines and circles with pixels. There are clever algorithms (I still marvel at Bresenham’s circle) but the output is for humans, not machines. A machine simply sees an array (about 30*36 = 1080) of white, grey and black pixels.

No lines.

No A.

We’ve got to reconstruct the A. (AMI asks “Couldn’t the publishers publish proper A’s?”. “No AMI, they can’t, because they want to do the same thing they were doing 20 years ago – simulate paper”). Here’s a bit of it:

Remember “0″ is black and “255″ is white. You can see the SW corner of the A. I have to teach AMI how to recognise it.

AMI: Are all A’s the same size?

P. No. They can be as small as 7 pixels high (anything smaller is unreadable for humans).

AMI. Are they all the same aspect ratio?

P. No. Some are thin and some are fat.

AMI. Are all the lines the same width?

P. No. There’s Helvetica light (thin), Helvetica (medium) and HelveticaBold (thick)

AMI: Is the A always symmetrical?

P: No, it can be slanted (oblique, italic)

AMI: Are there other fonts besides Helvetica?

P. Zillions. At least ten thousand.

AMI: so you will have to teach me a hundred thousand fonts.

P. I can’t. Some of them are Copyright

AMI: That means you go to jail if you use them and redistribute them?

P. More or less.

AMI. I will not be able to recognise all As.

P. May of them are VERY similar. I will teach you how to recognise similar characters. First we have to convert them to gray.

AMI. I have some convertToGray() modules.

P. Good. Then we have to clip them.

AMI. That’s what you are writing now? Trimming off the white pixel edges.

P. That’s right.

AMI: But some are “nearly white” (240) is that white?

P: we shall set a heuristic cutoff – maybe 240, maybe higher.

AMI: How do you tell?

P. Trial and error. It’s very boring. What is worse is that I am doing some of the things for the first time.

AMI: But you should’nt make mistakes. That’s why we use JUnit and Maven and Jenkins.

P. But I don’t know what methods work best. Maybe Otsu? Maybe Hough? There is no single solution.

AMI. Perhaps you can get some hackers to help you. They might know more about Java Images.

P. Good idea. Java’s ImageIO is not very cuddly – for example a missing file does not throw FileNotFound, but NullPointer.

AMI. ARE THERE ANY JAVA IMAGE HACKERS WHO CAN HELP PM-R? You don’t need to know any chemistry!

P. Thanks AMI. Hackers, please leave a comment on the blog. And there’s a very exciting way of meeting them that I am not yet allowed to blog – a few days.

AMI. Communal knowledge makes projects go faster. I like having several people writing my code. We have good tools for keeping in synch.

P. I took days – an experienced image guru would have done this in a morning.

AMI. So we have clipped the images. Now we have to make them the same size?

P. Yes. And I found a very useful library Imgscalr.

AMI. Yes, you installed and tested it on a few characters . Did it work?

P. Seems to. Now we have to compute correlation… and then see how unique the results are.

The post Why Shuttleworth Chose Me appeared first on Shuttleworth Foundation.

As with all problems I look to see whether there is a solution already. I need a FLOSS (Open) pure Java solution. I have found three possibilities:

• Tesseract. Not pure Java
• Java OCR (was simple but now so complicated we don’t even know how to run it! Help would be useful!)
• Lookup (a method for correlating character images – but where to start?).

So we have decided (regretfully) we have to write our own. If anyone has a pure Java OCR solution that doesn’t require training please put us out of our agony. Ultimately it should do a  subset of Unicode including Greek, Maths, symbols, etc.  I’ve hacked several ideas including thinning and topology (which is still on the boards). But recently I came to the conclusion that to make a start we should correlate known characters with unknown ones. Since most scientific images use Helvetica (or similar sans-serif) or Times-New-Roman (or similar serif) or Courier (or similar monospace) we can start with those to compare against.

What’s this?

From the “House at Pooh Corner” quoted without permission but with Love (A A Milne was my aunts’ uncle).

Eeyore had three sticks on the ground, and was looking at them. Two of the sticks were touching at one end, but not at the other, and the third stick was laid across them. Piglet thought that perhaps it was a Trap of some kind.
“Oh, Eeyore,” he began again, “I just–”
“Is that little Piglet?” said Eeyore, still looking hard at his sticks.
“Yes, Eeyore, and I–”
“Do you know what this is?”
“No,” said Piglet.
“It’s an A.”

How do we know it’s an “A”? (Douglas Hofstadter wrote deeply on this).  My simple solution is “does it have a good pixel wise correlation coefficient with any of the As in three font families after scaling and translation?”.

I’ve spent a week writing code (very badly) to do the scaling and translation. Part of the problem is that I was in the Australian desert with very limited wifi and no geek companions and broken chunks of time. I’d write a bit each day, spend my time remembering what I had done, and then hack away at tests and then start fro scratch again.

I’ve now come back and found a simple online solution:
BufferedImage bimage = Scalr.resize(bimage, Method.QUALITY, Mode.FIT_EXACT, width,
height);

from the imgscalr library (see this post http://e-blog-java.blogspot.com.au/2012/02/cropping-rotate-and-resizing-images.html )

Doh! I could have got all this working a week ago.

Yes, if I had known there *was* a solution and where to look. Sometimes it takes a week to find where to start. You look on Stackoverflow, Google a bit, tweet a bit and sometimes it takes minutes, but sometimes takes a week. It really helps to have a geek cloud round you. I do reasonably well on these things but when you convolute the different languages (C, Java, Python, Perl, R, JS, etc.) with Open and Easy then the message becomes more diffuse. (There are some packages – e.g. OpenCV – that can take a week to know where to start!).

Rabbit came up importantly, nodded to Piglet, and said, “Ah, Eeyore,” in the voice of one who would be saying “Good-bye ” in about two more minutes. 
      “There’s just one thing I wanted to ask you, Eeyore. What happens to Christopher Robin in the mornings nowadays?” 
      “What’s this that I’m looking at?” said Eeyore, still looking at it. 
      “Three sticks,” said Rabbit promptly. 
      “You see?” said Eeyore to Piglet. He turned to Rabbit. “I will now answer your question,” he said solemnly. 
      “Thank you,” said Rabbit. 
      “What does Christopher Robin do in the mornings? He learns. He becomes Educated. He instigorates–I think that is the word he mentioned, but I may be referring to something else–he instigorates Knowledge. In my small way I also, if I have the word right, am–am doing what he does. That, for instance, is?” 
      “An A,” said Rabbit, “but not a very good one. Well, I must get back and tell the others.”

So Eeyore has to refactor his “A”:

“What did Rabbit say it was?” he asked. 
      “An A,” said Piglet. 
      “Did you tell him?” 
      “No, Eeyore, I didn’t. I expect he just knew.” 
      “He knew? You mean this A thing is a thing Rabbit knew?” 
      “Yes, Eeyore. He’s clever, Rabbit is.” 
      “Clever!” said Eeyore scornfully, putting a foot heavily on his three sticks. “Education!” said Eeyore bitterly, jumping on his six sticks. “What is Learning?” asked Eeyore as he kicked his twelve sticks into the air. “A thing Rabbit knows! Ha!”

So I have refactored my code by jumping on it and kicking it into the air

But I am not bitter – I am happy!

How do I know? Because it’s being created by fantastic people and because OKFest in Helsinki was fantastic.

And I love the theme. It echoes my own thoughts. So here…

A Theory of Change

The programme for the 2014 edition of the festival is fuelled by a theory of change. Using this theory as our outline, the event provides an ideal opportunity for the open movement to come together to co-create the roadmap that will guide its next steps.

Our Theory: we believe that Knowledge, Tools and Society are the levers of Change. As such, Knowledge, Tools and Society will be the three streams that form the architecture of the programme.

Knowledge: Knowledge informs change. At OKFestival we’re keen to discuss ways of unlocking, expanding and sharing knowledge through open access, open research data, open educational resources, open science, data journalism and campaigning, data visualisation and literacy.

Tools: Tools enable change. We’ll be discussing facilitating the flow of knowledge through non profit technology, open source software, open hardware, design, architecture and urban planning.

Society: The group(s) who effect change.  Topics may include designing institutions, building communities and protecting environments. Additionally, powering economies through open government, transparency, open tech businesses, open development, open education, open culture, open sustainability and open economy will feature on the programme. Security and privacy-related topics also fit into this stream.

The festival will weave together these three streams of open knowledge innovation and impact. Each session will go deep within its realm as well as identifying interdisciplinary features that span different domains or disciplines.

 

This is exactly what the innovation in this century is about. It’s inclusive.

• Everyone has a right to all public knowledge at zero access cost and without barriers. Anyone can use it for any purpose
• Tools are becoming universal. We are creating the gift economy where everyone wishes to make tools available to everyone for free. And where the cost of tool production is dropping rapidly, whether it be software or material manufacturing.
• We are creating communities in easy that have never happened before. We can find our partners in an email or social network interchange anywhere and any when in the world. We move in and between communities.

And traditional organisations like cities and funders and voluntary groups and governments are understanding the power of the community. You’ll meet them all at OKFest.

It is a great time to be alive and to be part of it.

The post OKFest 2014 will be sensational; it’s inclusive and empowering appeared first on Shuttleworth Foundation.

Looking at PedroS’s problem we’ve narrowed it down to one image and one caption. Note that this single paper could give 20 times this amount of information and there are millions of papers. But we’ll “zoom in” to this single task

Here’s the image. If you zoom in you’ll see it’s made of pixels

There are no explicit characters or lines – only groups of pixels that represent them. (This is actually very high quality compared with many pictures.) Interpreting them is tricky, but we’ve done most of the hard work (hackers welcome to help!). What we have to do is:

• find the data points (there are 9, represented by diamonds)
• the straight line relationship
• the x-axis
• the x-axis scale (tick marks and numbers 0.0031 -> 0035)
• the x-axis quantity (T)
• the x-axis units (1/K)
• the y-axis
• the y-axis scale
• the y-axis quantity (ln k) – there are no units as logarithms are dimensionless

Knowledgeable scientists will already have spotted there is an error in the plot.  An Arrhenius plot should have 1/T, not T as the x-axis. It’s almost certainly a levelling error, not a data error, bt even so it’s an error.

This is the holy “version of record” and it’s wrong!!.

I have asserted that on average every paper contains errors. Not necessarily serious ones, but errors all the same. A graduate student would have to recreate this plot to pass their exam.

Could our AMI program detect this automatically? In principle, yes – quite easily. We’d need a template for “Arrhenius plot” and the dimensions of the x-axis.

So that’s our contention that every paper must be examined by machines for errors. Any publisher who prevents us doing so is trying to support its monopoly at the cost of allowing BAD SCIENCE. That’s why we have a moral right an imperative to use content mining for the whole literature.

To check for errors (and worse).

A publisher who defends their right to condone bad science will lose in the court of public opinion.

(Now, I didn’t know when I started this post that there was an error in it!  I’ll continue with what I wanted to say…)

We now have to interpret what the the semantic of the plot are. Let’s look at the caption for (C) and annotate using the Internet and especially Wikipedia.

Wikipedia??? Isn’t that unreliabe and rubbish??

NO. No more so than anything else (remember the current paper has at least one error, that would never persist in Wikipedia). And in science the quality of Wikipedia is extremely high (NB I wrote some of it). So let’s see how much of the caption we can interpret (this has links to Wikipedia, etc.)

determination of the activation energy [http://en.wikipedia.org/wiki/Activation_energy ]  of DPOR catalysis. In an Arrhenius plot [http://en.wikipedia.org/wiki/Arrhenius_plot] the logarithm of activity [http://en.wiktionary.org/wiki/catalytic_activity] (ln k, where k is the initial rate [http://chemwiki.ucdavis.edu/Physical_Chemistry/Kinetics/Virtual%3A_Kinetics/Method_of_Initial_Rates] of Chlide formation in the standard DPOR assay) is plotted versus the reciprocal of the absolute temperature [http://simple.wikipedia.org/wiki/Absolute_temperature] in K.

Over half the semantics are precisely described in Wikipedia. In sufficient detail that our program AMI could be taught to understand them. The only things missing are “DPOR” and “Chlide”.

*I* don’t know what they are. There is no shame in ignorance. Can we find out?

They should be mentioned earlier in the paper – let’s scroll back to the abstract…

During chlorophyll and bacteriochlorophyll biosynthesis in gymnosperms, algae, and photosynthetic bacteria, dark-operative protochlorophyllide oxidoreductase (DPOR) reduces ring D of aromatic protochlorophyllide stereospecifically to produce chlorophyllide.

What’s “protochlorophyllide oxidoreductase”? AMI can look in: http://en.wikipedia.org/wiki/Protochlorophyllide_reductase

and Chlide..?? Explained in the introduction:

Protochlorophyllide (Pchlide)² is a central metabolite for the biosynthesis of chlorophylls (Chl) and bacteriochlorophylls (bChl). In photosynthetic organisms two distinct enzymes catalyze the stereospecific reduction of ring D of the aromatic Pchlide to form chlorophyllide (Chlide) (1–3) (Fig. 1). The first enzyme is the light-dependent Pchlide oxidoreductase (LPOR; NADPH Pchlide oxidoreductase, EC 1.3.1.33).

and this is really valuable. It has an Identifier. An EC number. This highlights the massive work that the biology community has done in providing a semantic infrastructure for public science. Have a look at http://enzyme.expasy.org/EC/1.3.1.33 and marvel at the linked information.

To summarise so far:

Many articles in science are full of semantically supported Facts. There are dictionaries, ontologies and identifier systems. Putting them all together make a vast semantic resource – the Semantic Web. And bioscientists can make massive use of computers – it’s so exciting.

And chemistry? Well the American Chemical Society tried to close Pubchem and threw the lawyers at Wikipedia to preserve its monopoly of information. Which is now about 20 years behind the cutting edge of scientific information.

So please, ACS, have a change of heart and embrace the public value of semantic chemistry. Because it’s going to happen anyway.

In the next post(s) I’ll explain how we get real numbers and labels out of the plot.

The post Content Mining; Extracting Facts from Plots – 2; we find errors in the paper appeared first on Shuttleworth Foundation.

People frequently ask me what is the use of isolated Facts (I’ll use this typography as FACT has an unpleasant association). I’ll be giving examples of this and I hope they will come from YOU! But here is one of the universally valid type of Fact – the X-Y Plot. It’s common to call these “graphs” and that’s fine, but graph has other meanings as we’ll see in later blogs. Since there are many types of plot (and I’ll be showing how we can hack all of them) I’ll call this an XYPlot.

PedroS has commented: PedroS says:

February 27, 2014 at 4:15 pm  (Edit)

Would it be very difficult to automaticaly detect graphs in papers and extract the values of the data points? I am now extracting (by hand) those data from an Arhenius plot, which I intend to use for an Eyring plot 
>See graph 3.c from dx.doi.org/10.1074/jbc.M708010200

So here we have the crux. Numeric data are often plotted as an XYPlot. This is a good way of communicating for most humans. They can tell what’s related to what and how well. But then the plot is published as an IMAGE. The humans can still read it but the machines can’t. So the data are lost.

“I am now extracting (by hand)” … the tragedy of our failure of vision in this century of electronic enlightenment.

There are probably 1 million graphs in the literature that people might want to get data from. Let’s cost a scientist’s time at 500 a.c.u per day (arbitrary currency units). Let’s say it takes PedroS half a day. That’s 250 million dollars a year in wasted scientist time. And that excludes the opportunity cost. And when we come to other diagrams (phylogenetic trees, chemistry, bar charts, etc.) it’s easily up to billions…

Here’s the paper. I know one or two people connected with J. Biol. Chemistry and some of my close associates have published in it. I think its standards are as high as almost any journal. It’s not primarily Open Access but it makes papers freely readable after a fairly short period. (Please update…).

The paper is Copyright © 2014 by American Society for Biochemistry and Molecular Biology. I am going to copy the plot without their permission and show how to extract the data. I think I can defend it legally but anyway I don’t think they will mind – and I don’t think they will send lawyers. And, in any case, in 1 month it will be legal…

Here’s the link to the image .. image  and here’s what’s in it (

(BTW I understand this paper enough to comment authoritatively on some of it). This diagram contains four sub-diagrams. This is not done for scientific reasons, it’s probably because the authors were charged per-diagram. The literature is full of this unnecessary jigsaw of information. So diagram A and C have no relation – they are bundled to save money and/or pixels.

What does diagram C mean (to a human)? We have to look at a caption. And here it is:

FIGURE 3.

Purification of recombinantC. tepidum DPOR subunits, catalytic activity, activation energy, and CN^- inhibition assays. A, SDS-PAGE analyses of purified, recombinant BchNB complex and BchL. Lane 1, molecular size marker, masses as indicated (×1000); lane 2, purified GST-BchN complexed with BchB, cell extracts from E. coli BL21(DE3) Codon Plus RIL containing pGEX-bchNBL^* after isopropyl β-D-thiogalactopyranoside induction, affinity chromatography on glutathione-Sepharose, extensive washing, and glutathione elution; lane 3, BchN and BchB were recovered from glutathione-Sepharose after proteolytic cleavage; lane 4, E. coli extracts from cells containing pGEX-bchL after isopropyl β-D-thiogalactopyranoside induction, affinity chromatography on glutathione-Sepharose, extensive washing, and glutathione elution. B, absorption spectra of standard DPOR assays using E. coli cell extracts or reconstitution assays after 20 min at 35 °C and acetone extraction.Trace a, standard DPOR assay containing 30 μl of E. coli extract; trace b, assay mixture without dithionite; trace c, assay mixture without ATP;trace d, control reaction without cell extract; trace e, reconstitution assay using 20 μg of purified (BchNB)₂ and 20 μg of purified BchL₂;trace f, control reaction using 20 μg of (BchNB)₂ but no BchL₂; trace g, control reaction using 20 μg of BchL₂ but no (BchNB)₂. C, determination of the activation energy of DPOR catalysis. In an Arrhenius plot the logarithm of activity (ln k, where k is the initial rate of Chlide formation in the standard DPOR assay) is plotted versus the reciprocal of the absolute temperature in K. D, cyanide inhibition of DPOR. The activity of standard DPOR assays (15 min at 35 °C) in the presence of 0–60 NaCN is plotted against the concentration of NaCN. 50% inhibition of DPOR is achieved at 36 mM NaCN.

It’s cognitively appalling (in part because of the unnatural format into4 sub diagrams. So let’s separate out our graph (C). This is trivial for a human – a bit harder for AMI but it’s possible.

C, determination of the activation energy of DPOR catalysis. In an Arrhenius plot the logarithm of activity (ln k, where k is the initial rate of Chlide formation in the standard DPOR assay) is plotted versus the reciprocal of the absolute temperature in K.

These are really valuable Facts and metadata (metaFacts). I understand half of it. I don’t understand “DPOR” or “Chlide”. But the rest are standard physical chemistry . (BTW Arrhenius  http://en.wikipedia.org/wiki/Svante_Arrhenius was a genius – in his thesis he developed the ionic theory and almost failed because the assessors said it was rubbish. In today’s bean-counting universities he would have been thrown out. Fortunately he continued, winning a Nobel prize and predicting the greenhouse effect of Carbon Dioxide).

The figures and their captions are often the most important part of an article. Looking at this one diagram tells you at least as much about the content as the abstract. Can AMI understand it?

Probably. The first sentence reads:

determination of the activation energy of FoobarEnzyme catalysis

(Foobar is a general placeholder (metasyntactic variable) for some entity). This phrase probably occurs 10,000 times per year in the scientific literature. So we (I mean YOU as well as me) can train our AMI program to recognise it (more in later blogs). With more work we can train AMI to understand the other 3 diagrams.

So can we reconstruct the data from the plot? Two years ago I thought NO. Now I think absolutely YES. And in the next blogs I’ll show you how. We’ve written much of the software (hackers very welcome!) and then you can use it!

The post Content Mining; Extracting facts from Plots and how we can save billions appeared first on Shuttleworth Foundation.

The holy grail of every funder is sustainability, an idea and approach living long after the money has run out. That is why we fund people not projects. The only true way to sustainability is not a business plan but a champion, someone who will drive an idea through an ever changing landscape, to make a real difference in the world.

We are looking for social innovators who are helping to change the world for the better and are seeking support through an innovative social investment model.

 

My new entry is here: http://www.shuttleworthfoundation.org/fellows/current/peter-murray-rust/

This is incredible. I’ve had a week or two to adjust but I’m still finding new ideas, visions, people on a daily basis.  So this is a first reaction.

I am going to change the world for the better. Yes. Over the last few years when people have asked me what I want to do I reply “change the world”. It’s what we should all aspire to. And this is the most concentrated  time of innovation in the history of the planet and it’s much easier. In the past heroes such as Diderot had to rely on print to reach people – I can reach millions of people with a few keystrokes.

It’s this ability to create communities that makes us different from our predecessors. As exemplars I look to my own immediate circle of electronic communities: Wikipedia, Mozilla, Open Knowledge Foundation, Creative Commons, Open Rights Group, Blue Obelisk …

All started by people – often just one. And all self-sufficient without their founders. That’s my immediate model for sustainability. I don’t know exactly *how* it will happen , but I am certain it will. (Certainty is an essential ingredient of success). So the goal is to build a community of vision and practice.

This year I have undertaken to liberate 100, 000, 000 FACTs from the scientific/technical/medical literature. FACTs belong to the world, not individuals and not corporations. I use uppercase to stress that they are not protectable as Intellectual property (IP). FACTs save lives (think helicobacter and ulcers). FACTs help to create new materials. FACTs lead to better decision making (e.g. climate change). FACTs generate new information-based industries which generate new wealth (the 4 Billion USD invested in the human genome generated 700 Billion of downstream wealth.  (I’ve blogged a lot about the Content Mine and I’ll be blogging a lot more, of course).

Because it is freely available to everyone on the planet who can connect to the Internet.

Put most of all I must thank the Shuttleworth Foundation. They have a wonderful vision and wonderful people. There’s a lot I am discovering.

But, simply, they put in the effort to make sure people succeed.

They have a wonderful infrastructure that I suspect few other funding bodies can emulate. I have a very real relationship with  Karien Bezuidenhout and Helen Turvey who run the Fellowship program.  We’ve spent a lot of time bouncing ideas around and I shall be meeting Helen in a few days in London. Karien and I will have virtual meetings twice a month! This can make all the difference to being focussed and setting achievable objectives.

And I know several of the Fellows already. Rufus Pollock (OKFN), Daniel Lombraña González (Crowdcrafting)  …

… and Fracois Grey who will be my buddy / mentor. This is a wonderful idea. I’m hoping I can visit New York and run a workshop there with his Citizen Science community.

And then there is the community of the Fellowship – again this is a wonderful resource. Fellows come from all disciplines and experience and the cross-fertilisation will be massive. We meet virtually every week and we have 2 physical meetings a year. I’ll be doing a lot of listening.

It’s a huge responsibility, but that’s absolutely how it should be. I shall give it my best. I cannot know how it will work out in detail. I’ve a loose group of current collaborators and I’ll be talking with Helen about the best way of involving them.We’ve already plotted some activities.

Massive thanks to those who have helped with my application, acted as sounding boards and acted as referees.

Shuttleworth is the difference being *hoping* your ideas will take root  and *knowing* they will.

The post I have been awarded a Shuttleworth Fellowship to change the world; my first reactions appeared first on Shuttleworth Foundation.

Kristina Alexanderson (Photo: Peter Alexanderson, CC (by))

At Commons Machinery, we care a great deal about attribution. Not only because we are trying to incorporate it into software, but also because we care about the internet and people who put an effort into making the internet a more inspiring place.

One person who also cares about the internet and how creatives are awarded for their creative efforts is Kristina Alexanderson. She is based in Stockholm, Sweden, is project lead with Creative Commons Sweden, and has spent the past 9 years working for Webstjärnan. Set up under the organization responsible for the Swedish top level domain names, Webstjärnan (the web star) is a competition that focuses on getting young students in Sweden to use the internet as part of their ordinary school work. Part of her work also involves teaching students and educating teachers about the importance of attribution. We’ve talked to her to hear her view on why attribution is important and how she educates others about the topic.

“I believe that creators who share their work on a Creative Commons license don’t do it only out of altruism. They want something back and they want to be recognized for being generous and supportive. Attribution is the cost you pay for using other people’s Creative Commons-licensed works. On the other hand, when you are using other people’s resources, attribution means that you have to tell the world that it’s other people’s work,” she says via a Skype connection.

According to Kristina Alexanderson, this way of seeing attribution is similar to how we have been taught to cite our sources when doing academic work. One of her main arguments when teaching students and teachers about attribution is the academic one; in academic work, part of getting things right relies on your ability to show that you are well read by using citations.

“Attribution ought to be part of a literacy to teach students and teachers. It ought to just be common sense.”

 Kristina Alexanderson suggest that the one of reasons why attribution online isn’t a given, is the growing importance of images in our culture. We have already learned how to attribute text sources in school essays, because of the significance of written texts in our society. However that has changed with the internet. Now photographs, images, and videos all play a central part in how we communicate.

When teaching students and teachers to attribute, it is actually not the students that can be the hardest to persuade. Educating the teachers is sometimes the biggest part of her job. Ms. Alexanderson is often met with arguments such as “Oh, it is so difficult to remember all that. I don’t know who the photographer and I don’t want to know and who cares – the photo is there and I want to use it.” Another argument that she uses, when arguing the importance of attribution, is the simple “wouldn’t you want to be attributed for your work?”.

“The common issue with attribution is that it is too difficult. I actually think that argument is bullshit, because it isn’t that difficult to find a name and to tell the world who the creator is. I think we don’t want to tell, because [we feel like] it diminishes our work. Maybe we can trick the world into thinking that we are the creator of this,” she says.

One the most eye-opening experiences when teaching attribution usually comes when students or teachers share something online that they are proud of.

“You have to be a creator to actually truly see the importance of attribution and you have to be proud of your work. You have to share something that you actually want other people to be part of. And then people really really want to be attributed. We want to be attributed to something we are proud of. When we are proud of our children, we want them to say “this is my mom”, or I want to say “this is my child.” It is the same with the things we share online,” says Kristina Alexanderson.

Mozilla started with a very basic question: How can we create a web that is more open? In answer to that question we witnessed the growth of a global community of Mozillians around the world who have an ingrained instinct to roll up their sleeves, learn from and teach each other, and build the solution to a problem.

The Mozilla community fundamentally understands that in order to affect change, people need to be makers, not just consumers.

After all, it’s this instinct to teach and build that enabled us to develop Firefox: 10 paid staff and a global army of volunteers contributed to the creation of a browser that beat out the biggest software company in the world. And we didn’t just build a better browser — we demonstrated the power of teaching. Millions of us installed Firefox on our friends’ and families’ computers—and explained what Mozilla stood for as we did this.

Fifteen years later, the world faces different problems.

In this new, post-Snowden era, it feels like everyone is talking about — and craving — a more open and trustworthy internet. The world has a better understanding of how people are being tracked online, and of the delicate balance between privacy and a world where we are all constantly connected. We live our lives online, and store everything in the cloud, yet our lives depend on technology and networks that too few users really understand.

And so, as Mozilla, we strive to answer the same fundamental questions that guided us at the beginning: how, today, can we strengthen an internet that is open and trustworthy? What is the next set of tools to enable people to protect their privacy? How best can we teach everyone basic web literacy skills like how to secure their information? Should we use our influence to ensure government and corporate policies help make the web more open and trustworthy? How do we do this work at scale, recognizing that billions of people will soon be online?

We’re trying to answer these questions in a number of ways, but we can’t do it alone. That’s why we are thrilled to join foces with the Knight Foundation and Ford Foundation on this year’s Knight News Challenge, which will fund $2.75M in grants to find and support great ideas.

In part, this new Knight Challenge aims to fund the technology, education programs and campaigns that will begin to satisfy the craving we have for a more open and trustworthy web. But, it also aims to spark a conversation around how to shape the next era of the web – an era where openness, security and innovation regain their status as elevated principles.

Mozillians bring our very practical ‘roll up our sleeves and build the future as we want to see it’ ethic and that is exactly what we need now. We’re the right ones to figure out how we can best leverage the mechanics, culture and citizenship of the web to keep it open.

So, let’s all commit to help out and participate in The Knight News Challenge. I’d love to see as many people as possible from the broader Mozilla community submit ideas for tech and propose new education programs.

Along with Knight and Ford, Mozilla is trying to build a wave of people creating the web we want. Let’s help start that wave.

The post A $2.75M Challenge to Create a More Open Internet appeared first on Shuttleworth Foundation.

To ensure I embarked on my journey in the right direction, I opted to take my time in surveying both my own thoughts and the landscape of opportunities. I spent the first half of my Summer thinking and reading. Roommates may remember this period as a time that I didn’t leave the couch, that I often passed up hanging out with friends in favor of reading Wikipedia and thinking, alone, for hours, sometimes through to the morning. I was gathering and formulating what makes me tick, what is meaningful in my life, the goals I have for myself, and the change that I want to make in the world.

I decided I fit the description of a social entrepreneur, and that I intend to use business, engineering, and design to tackle some of the biggest challenges we face today. With my newfound framework and topics as broad as agriculture, transportation, and governance piquing my interest, the time was right to move forward. I had a direction.

Already having had a loose idea to help fix agriculture, I made further developing that idea my primary focus. For the remainder of Summer, I formulated into a 50 page paper: FarmBot – Humanity’s open-source automated precision farming machine. The paper details everything: from the initial idea, to the vision, to a prototype design, to the business plan and more. But most importantly, it calls for help. I recognize that nobody can solve these challenges alone, and that I want to collaborate, not compete. What’s mine is yours, let’s do this together.

I self-published the paper on September 20th and sent it out to strategic communities on the Internet. Before long, I had assembled an international and interdisciplinary team of people with a shared interest and motivation in the project. We began work. Now 5 months after publishing, the team is about 20 people strong and we’re moving forward quickly on all fronts.

But what I’m most excited to say in this post, is that this Saturday marks the first day of FarmBot being my full-time job! I’ve been accepted into a Fellowship program by the Shuttleworth Foundation, providing me with $125,000 for project funds, my salary, and travel expenses. I will be working under this grant for a full year and I hope to bring FarmBot to market in that time. In May, I will be traveling to Budapest to meet the other fellows and the foundation staff for a week long conference. After, I plan to see more of Europe by bicycle, with a focus on meeting some of the other project contributors. While at home, I will be basing my operations out of SLO MakerSpace, and I’m incredibly stoked to transition my role there from manager to maker.

The times are exciting, the road is long, but I think I’m heading in the right direction!
