Taking Openness to the Next Level

Yesterday I wrote about one particular issue with standards: the fact that the associated patent licensing (if applicable) can shut out free software completely. But it's clear that the problems go much deeper: the entire standards-making process is conducted in a way that is often the antithesis of openness. That's not just bad for free software, it also means that the standards themselves suffer, as do many potential participants who are unable to contribute as fully as they otherwise might. Here's an interesting attempt to rectify many of those problems by drawing on the manifest success of the open source approach:

Another Reason to Run GNU/Linux...

And a pretty important one:


The Home Office has quietly adopted a new plan to allow police across Britain routinely to hack into people’s personal computers without a warrant.

So why might GNU/Linux help? Well:

He said the authorities could break into a suspect’s home or office and insert a “key-logging” device into an individual’s computer. This would collect and, if necessary, transmit details of all the suspect’s keystrokes. “It’s just like putting a secret camera in someone’s living room,” he said.

Police might also send an e-mail to a suspect’s computer. The message would include an attachment that contained a virus or “malware”. If the attachment was opened, the remote search facility would be covertly activated. Alternatively, police could park outside a suspect’s home and hack into his or her hard drive using the wireless network.

Er, and how are they going to break into my system to install the keylogger if they don't know the password? Attachments won't work: I'm generally clever enough *not* to open them, and even if I did, they wouldn't do much on a GNU/Linux box. And hacking my hard disc through the wireless network? I don't think so.

Looks like free software is becoming even more about freedom....

No Longer Wireless-less

Now that open source has largely overcome its earlier problems with limited application availability – there's practically no area today that is not served reasonably well by free software – the remaining challenge is hardware support. That's obviously harder to resolve than the earlier software dearth, since it depends not on the willingness of coders to roll up their sleeves and write stuff, but on hardware manufacturers to release either open source drivers, or at least full specs for their kit. But even here, open source continues to demolish the barriers....

OpenSpimes

Open what?

A "spime" (the word -- a contraction of "space" and "time" -- was coined by sci-fi writer Bruce Sterling) is an object that, thanks to GPS and sensors, is aware of where and when it is, and can record and communicate these data. OpenSpimes are designed to allow everyone to record and visualize environmental (or other) data, to store them, publish them, blog them, compare them, mix and mash them up.

The first spime they've designed is a smart application of distributed computing in the service of sustainability. It can measure the CO2 level in parts-per-million in the surrounding air, and through a bluetooth link to a cell phone (or an alternative link to a laptop or other wireless channels) can relay that information back to the OpenSpime servers. There they can be mashed up and aggregated on Google Maps in almost-real-time.

Why We Need a Knowledge Commons

Here's a neat device:

With Exbiblio, you have seamless, direct access to digital information and the world of the Internet. Imagine once again that you are reading your newspaper, but instead of tearing out an ad or article, writing a reminder or recording a voice message, you use your portable, hand-held scanner to capture just a snippet from the article or ad, swiping it across the text as if using a highlighter.

When you connect your Exbiblio scanner to the digital world -- for example, by wirelessly connecting to the "smart" phone or PDA you are carrying -- the Exbiblio solution instantly searches for the information you have captured, and digital versions of the paper document are found and stored.

Sounds cool - but it depends critically on having free access to that cloud of information. In other words, it depends on the existence of a readily accessible knowledge commons that it can draw upon seamlessly. If such devices had to pay for every snippet they pull down, the knock-on cost and infrastructural complexity required to keep track of who is demanding their shilling will kill it.

Open Motes

Wow, a new one on me:

SquidBee is an Open Hardware and Source wireless sensor device. The goal of SquidBee is getting an "open mote" to create Sensor Networks.

The main concepts behind SquidBee are:

* Self-powered

* Wireless Comunications

Repeat with me: "Ubiquity, Ubiquity, Ubiquity..."

How does SquidBee work?

1. Acquires values from environment parameters: temperature, humidity, lightness, presence, pressure or (almost!) whatever you can sense.
2. Operates with these values, when required.
3. Transmits these values using a low power comsumption wireless technology (ZigBee).
4. Sleeps until next timeout and repeats from the first stept.

Second step is not always necessary, depending of the calculations needed it may be better to make them in receiver computer to save nodes energy.

An open mote? What does it really mean?

It means every part of the mote is accessible and can be studied, changed, personalized, ... From the schematic circuit to the source code of the programs that are running inside the mote.

Easy Access to IPv6 at Last?

You probably don't realise it, but the Internet is a dinosaur. More specially, the Internet numbering system is palaeolithic, and needs sorting out. Ironically, the solution has been around for years (I first wrote about it nearly a decade ago). It's called IPv6, and instead of the measly 4 billion or so addresses that IPv4 allows (and which are allocated in a particularly arbitrary way), IPv6 will give us

340,282,366,920,938,463,463,374,607,431,768,211,456

of them, which should keep us going for a while.

And yet we hear little of IPv6 these days. So I was glad to see that down-under they are doing something on this front with the IPv6 for e-Business initiative. As well as scads of useful IPv6 resources, this site also has links to a highly-practical outcome of the Australian project, the memorably-named "Easy Access Device":

The Easy Access Device (EAD) has been developed with the purpose of providing a small businesses (leas than 50 employees) with a simple, easy to use IPv6 Internet access device. The system is designed as a small unit that would be installed in a small business, and connects directly into a DSL, cable or wireless broadband termination unit (typically a modem). The unit provides the basic network services normally required at a small office network boundary for both IPv6 and IPv4 networks.

Apparently it's a PC box running Ubuntu. Providing a cheap solution is probably as good a way as any of moving on from the poor old IPv4.

GNU/Linux on the Desktop: Get the Facts

Some say that 2007 is the year GNU/Linux is going to make its breakthrough on the desktop - just like last year, and the year before that. So instead of looking forward at what might happen, why not look back at what did happen?

Linux on the desktop grew and matured in 2006. While some analysts reported a slowing of Linux penetration on the desktop in 2006, a number of significant milestones were reached that promise to continue to move the Linux desktop ahead in 2007. As Gerry Riveros, Red Hat product marketing manager for client solutions put it, "What I think was most important [in 2006] were all of the 'under the hood' incremental improvements that took place around printing, plug-and-play support, laptop enablement and the arrival of the compositing manager that allows for modern graphics."

These and other improvements are setting the next stage of growth for the Linux desktop. A number of projects and teams have moved beyond alpha positioning and ownership to focus on how their efforts contribute to overall desktop Linux objectives. "In 2006, it appeared that developers were aware of how each other's projects help to accomplish the shared goals of all the projects," said John Terpstra, Advanced Micro Devices Linux Evangelist. Over 70 of the key desktop architects have met three times this year to agree on focus areas that would make desktop Linux "just work."

Drawing Closer: Location Awareness

I'm afraid this is proprietary for the moment, but the idea's clearly generalisable:

Skyhook Wireless Inc....today announced at the 2007 International Consumer Electronics Show (CES) that ReignCom, a Korean manufacturer of media devices, will launch the Wi-Fi enabled iriver W10 portable media player with the Wi-Fi Positioning System from Skyhook Wireless. This device will be the first commercially available media player with location awareness...

The iriver W10 media player is designed for the 'urban explorer.' At a slim 14 mm thick, the iriver W10 comes loaded with full-function multimedia capability. The Wi-Fi Positioning System provides accurate location information by detecting Wi-Fi access points in range and comparing them against a database of geo-located points. Unlike GPS or cell tower systems, the WPS works indoors and in dense urban areas. Not only can a W10 user listen to music, watch movies, or play games on the go, but can also navigate and retrieve information about what is around them.

Why Wireless is Hopeless: Manufacturers are Clueless

Here's a thorough journalistic investigation into why manufacturers of wireless hardware have been less than helpful to the free software world:

Some of the non-responsiveness of manufacturers may just be bad PR work, but the same companies that wouldn't talk to me have also refused to reply to free software programmers who have requested the same information. The impression I got from most of these companies (excepting Intel) was that they were not at all prepared to deal with the issues of firmware redistribution rights and hardware API documentation requests. That they have ignored free software programmers' requests is not necessarily a sign of unwillingness to participate, but perhaps a general sense of confusion as to how they are able to help. No one seems to know whom to talk to at the company, and in some cases the proper documentation may not exist -- or it may belong to yet another company that the hardware manufacturer outsourced the firmware development to.

The Open Source Mesh Begins to Mesh

I'm a big fan of open source meshes, with their potential to offer alternative ways of accessing the Internet. I'd not heard of the Champaign-Urbana Community Wireless Network before, but this story on GigaOM about serious NSF backing for work on an open source mesh network looks promising.
