Community Supported Agriculture is sprouting up in many cities - over 100 groups are offering vegetable shares in NYC this year, up from 70 last year. Most are run on a volunteer basis.

CSAmazing is a hosted web management system for CSAs, taking care of the most common tasks, including payment, registration and volunteer coordination.With CSAmazing, volunteers spend less time working on admin, have an easier time delegating and can help the CSA group grow together as a community.

Common CSA tasks managed by CSAmazing include:

• easy sign-up for new members, including waiting lists once all slots are taken
• flexible payment options - thanks to generous support from non-profit food organizations in NYC, online payments via CSAmazing have no fees.
• cost calculators allow CSA organizers to forecast income and costs over the season, and share this info with the farmer
• email and social messaging tools to communicate with members and other CSA volunteers
• volunteer shift management - flexible re-scheduling, reminders and nagging emails make the process of staffing the CS pick-ups very smooth
• farmer communication, including details of vegetables each week
• tools to share data with other CSA organizers, to support local food efforts and build on experiences from other schemes
• a flexible, modular system, with optional extras including recipe databases, photo sharing and community food mapping

Getting a CSAmazing portal is simply a matter of registering with the main CSAmazing site, and filling out some info about the CSA. A custom domain is automatically set up, like this: crownheights.csamazing.org. With some simple customization though the admin interface, costs, shift times and other essential info can be entered.

Development of CSAmazing is open source, with a tiny team of developers supported by small contributions from participating CSAs and generous assistance from food-related foundations. Using a hosted solution means that backups, upgrades and security updates are taken care of. And since the underlying system beneath CSAmazing is a widely-used content management system and database, the foundations are solid.

The site is optimized to be undemanding. It runs smoothly on mobile devices and also older hardware and older browsers - helping CSAs reach a wide audience across the spectrum. The mobile version of the site even allows volunteer coordinators to check off shifts and edit schedules directly at the pick-up location.

Do you run a CSA? Say goodbye to miscellaneous google docs, long email chains and binders of volunteer shift coordination - sign up for CSAmazing today.

Introducing View Finder, a web tool for evaluating the visual impact of new transmission corridors.

Placing power transmission lines across the landscape is a necessary to transmit energy from source to destination. Until we get a breakthrough in efficiency, distributed and localized generation, new transmission corridors will be needed.

Choosing where to put corridors is contentious and drawn-out - for example, see the well-documented campaign against new corridors in Virginia run by the Piedmont Environmental Council. Reviews take a long time, and require data, expert analysis, public and stakeholder consultation. What if new tools could help make the processes more effective?

Here are two such tools:

• View Finder. A visibility analysis for the entire US, running in your browser. Discussed below.
• Path Finder. A collaborative platform for contributing, assessing and commenting on corridor options.

These two tools alone don’t resolve all the challenges around corridor placement, but they represent small building blocks towards more inclusive and open processes.

What is View Finder?

View Finder uses freely-available datasets to calculate what can be seen from a particular location. While detailed viewshed analysis is expensive and slow, View Finder provides a rough sketch of the same information in seconds, right in your web browser.

From your browser, click a point on a map, or draw a path to represent a transmission corridor (shown green in the screenshot below). View Finder overlays two colors: blue, showing locations that can’t see the point or corridor, and pink for locations that can.

Pre-set options relevant to transmission corridors allow you to specify the height of the pylons. Taller corridor infrastructure increases the size of the possible viewing area.

Vegetation cover data are used to calculate summer and winter views, where the corridor is located in or near a deciduous forest.

The ground cover also affects how likely you are to see the corridor from each location - forest gets in the way more than scrubland, for example.

After tweaking the settings, share, save or print the viewshed.

Behind the scenes, View Finder uses the National Elevation Dataset, and the National Land Cover Dataset. Both are stored in Amazon Elastic Block Storage, and called as needed by a GRASS GIS script running in Amazon Elastic Cloud Compute to calculate the visibility for the current location. Map tiles showing the view shed are generated on the fly by Mapnik and stored for re-use.

View Finder is an integral part of Path Finder - to be covered in a follow-up post.

Once the Open Neighborhoods Project is set up, the collaborative neighborhoods will form the basis for a fair re-districting of electoral boundaries. Rather than a few people determining how votes are accumulated, the same tools that support complex online collaboration for neighborhoods will be used to openly and fairly correct distortions in how we elect our reps.

Districts can be determined by a combination of commonly-held local boundaries, and geography. We have the tools: social media, versioning, open geographic standards, an engaged development crowd. Other nations have independent commissions to determine districts - but nothing open and crowd-sourced. There’s a lot of prior art in this area, most of it in the ‘dark arts’ category. Too bad.

This is the first Census year where a people’s redistricting is possible. Could be amazing. Let’s fix this embarrassment.

UPDATE: As well as prior art, there’s active art happening right now along the same lines at Redistricting the Nation. It’s hopefully obvious that none of the ideas on here are original research - just tossing out some sketch thoughts, rather than trying to give a state of the art with all due diligence. Turning on comments here soon so it’ll be easier to add other existing examples.

The Open Neighborhoods Project is an independent, crowd-sourced repository of neighborhood boundaries for the US. Three parts:

• a web map for anyone to contribute their neighborhood boundary
• tools to review and agglomerate different neighborhood outlines into commonly-accepted boundaries
• a data repository of current and previous neighborhood boundaries for download and re-use, forming a People’s Atlas of neighborhoods

Why

Only people who live in a neighborhood are able to define its geographic extent. But neighborhoods are the ideal data frame for many activities – local government, map making, planning initiatives, journalism, electoral districts, statistical comparisons, hyper-local news, agglomerations of geo-located data, etc. Most people seeking to describe a neighborhood are ill-informed to define its boundary. Centralized attempts to define neighborhoods will always fail.

A People’s Atlas of neighborhoods is possible, now: the web-based mapping tools are ready. The open process precedents for reviewing neighborhoods are ready. The data exchange standards are ready.

The published neighborhoods will form a foundation for relevant local action. Imagine mapping city-wide data using districts that were relevant to their residents. Imagine making statistical comparisons between areas that respected local definitions of place. Imagine re-drawing electoral districts from a base of non-partial local boundaries. Imagine your hyper-local news actually reflecting the place you live in. Imagine historians reviewing the changes in neighborhoods over time.

#1 The mapper

The Open Neighborhoods Project website is built around an open source, standards compliant web map. Any visitor to the website can register, adjust the map to show their area, and draw a boundary. This boundary can be named, and saved.

Optionally, the boundary can be constrained to snap to existing local boundaries, such as Census Blocks, county line, etc.

#2 Tools for analysis and review

Learning from open source software projects, the process for storing, reviewing and analyzing the neighborhood data is completely transparent. Individual boundaries can be recalled, or all boundaries overlapping a particular area. Comments can be attached to particular boundaries, and reviewed when inspecting a map.

A toolkit allows visitors to review all boundaries for a particular neighborhood, and select from present interpretations that dynamically processes the lines into a common boundary. Different methods of interpretation give different results.

Decisions about which interpretation to use as the “published” boundaries are made through open discussions via mailing lists, with guidance from an advisory committee of cartographers and demographic data experts.

#3 Data streams

The neighborhood boundaries are offered as dynamic feeds in all modern formats.

Users can download the neighborhoods into any map tool, including Google Earth, and other GIS platforms.

Feeds allow direct integration into other software tools. News sites can adjust their news coverage as borders are changed. Analysis built with census data on the neighborhoods will update to reflect the changed consensus of a boundary location.

Historic review allows anyone to inspect a boundary at any point in time.

Dot Dot Dot is a collaborative diagramming tool that embraces the messy nature of drawing out a process.

It’s more analogous to paper and pen tools than a fully-featured tool like OmniGraffle or Visio - think how Etherpad compares to Word.

But simplicity doesn’t mean Dot Dot Dot isn’t powerful:

Smart auto-layout tools allow you to focus on entering the diagram, not dragging boxes out from undereach other - click anywhere and start typing to create a new bubble.

Limited shapes and styling let you focus on the flow, not the look. But don’t worry: these default shapes are beautiful, but there’s full css control if you’d prefer to style your own or load a third-party template.

Magic imports - give Dot Dot Dot an outlined document (bullets, numbered, indented) and see a diagram produced.

Plug a feed into Dot Dot Dot to get a diagram that self-updates every time the feed changes

Export your diagram in a multitude of formats - images (you can link these into blog posts, etc), pdf, SVG for editable vector graphics, other graphing tools, outlines, dot files for graphviz, annotated text format with full revisions

But it’s really collaboration features that set Dot Dot Dot apart -

No logins: send someone a link, they can start editing right away

Review contributions using the innovative diagram timeline - Dot Dot Dot knows a layout tweak from a typo correction, and keeps track of changes to the diagram structure in a seperate stream to the formatting. Don’t let copyediting obscure bigger changes - quickly filter your timeline view to show the major diagram structure changes. Or maybe the color tweaks are your focus - choose to see those instead

Flexibility in diagramming approaches. Edit linearly if you think that way: add bubbles as parents, children or siblings of existing features.

But don’t be constrained - a collaborative workshop diagram is unbounded, and so is Dot Dot Dot. You can loop back, add comment bubbles, group bubbles together into neighborhoods, ringfence, box off, sideline, break the diagram apart, create nested sub-diagrams in boxes or links to other diagrams… Go wild.

Multiple authors can add separate items to a diagram simultaneously and join up later - ideal for note taking in a workshop or brainstorming an idea,

More mature diagrams will go through a lot of revisions - responsible contributors might want to leave a little note about their changes. Dot Dot Dot offers a few mechanisms for this: either comment in a bubble as you create it, so others can hover over it later to read them, or in the free-form notes area.

Or, hit the Commit With Comments button to tag your recent contributions with an explanation - the version control-like commit log can be reviewed later for an overview. Excellent transparency for changes. (There’s no need to ‘Commit’ for regular edits, of course - Dot Dot Dot saves incrementally all the time).

Owners and trusted authors can freeze some diagram elements. For example, you might want to get comments on a proposed timeline - draw the timeline and freeze it. Then, all comments and additions are an overlay on this frozen base.  Or freeze your starting point and goals, and let everyone map their way between them.

And there’s a finely configurable RSS feed so anyone can keep track of changes.

See you in diagramming heaven!

Csssearch (pronounced “scchearch”) is the first CSS search engine.

While other search sites index the web’s content, Csssearch goes after the layout. Using some clever cascade-aware logic as it munches CSS files, the search tools give you the web in its non-semantic glory. Who cares about the content, let’s look at the layout!

Search in your web history, delicious bookmarks or the entire web. Great for the forgetful, people with better visual memories and anyone looking for code or design case studies. For example -

• find that three column layout you saw last month
• get back to the page with those chunky black text labels
• look at some sites with pale blue backgrounds
• find examples of browser-compatible layout tricks
• enter a specific css phrase to see it in action

The API allows for some intriguing exploratory tools, including a neat dynamic layout browser. As you resize your mini version, adjusting headers, columns, spacing etc, real world examples of similar layouts are fetched from the index and displayed in thumbnail form below.

Csssearch: all the benefits of a search engine, with none of the content!

Key-iP Compact (pronounced keep, the iP stands for iPhone) is the fix for your finger-aching, composition skill destroying virtual iPhone keyboard.

Slotting either side of the iPhone, Key-iP creates an ergonomic split keyboard, with the phone in portrait mode in the middle. Learning from the wonderful portable palm keyboards, a simple grasp on the sides of the board unhinged it into two folding flaps. Either keep the iPhone sandwiched in the middle, or slide it out. In folded mode, the keyboard is only slightly bigger that the phone.

Pulling power from the base of the handset, the keyboard requires no batteries, and communicates with the phone via a very low power Bluetooth signal. The updated Apple spec for external devices allows the Key-iP to work without the onscreen keyboard - more screen real estate for editing.

Arrow keys, shift, caps lock, copy, paste and numerical keys. No batteries required, and so light you won’t notice it in your bag. Ideal for writing on the go, finally killing off your persistent netbook temptation.

You want to write seriously with an iPhone? Time to Key-iP it real with a Key-iP Compact.
