By the end of July it is necessary to take extra precautions, warning your ecommerce shoppers about the costs and conditions of the goods they buy online, or risk making the purchase unenforceable.
My good friend Finn Lewis from the amazing Agile Collective recently pointed me at Sass and Compass. Ultimately, both are higher level CSS languages for expressing design needs elegantly and powerfully, which then compile down into raw css.
Another friend (Candide Kemmler from Fluxtream) then mentioned LessCSS. It looks like there’s a lot of competing ideas on the css front!
A very important step, open sourced, with an astounding array of potential applications…
Problems with SSL and certificate signing
Cut the Certificate Issuers, who have exactly the wrong financial incentives, and appear to be deeply technically incompetent, out of the picture.
Revert to the “Web of Trust” concept which was central to the whole notion of Public Key Infrastructures from day one!
This is a collection of news snippets being gathered since mid February 2011.
The general trend is towards the EU beginning to enforce its data protection measures, possibly with the subtext of strengthening its EU centric data services providers (in a similar manner to Car safety standards acting in the first instance as a form of medium-term industry protectionism).
Sweden postpones EU data retention directive, faces court, fines
Sweden is to delay the implementation of the controversial EU data retention directive for a year, risking a heavy fine of up to ‚Ç¨68m, whereas Austria has decided to implement the directive after a European Court of Justice ruling in 2010. (Source
Police, Google and Facebook warned on data protection
European Justice Commissioner Viviane Reding said citizens have the right to proper data protection, and the “right to be forgotten”, and deserve national regulators which will enforce the rules. (Source
Police just rubber-stamping US data slurp
Members of the European Parliament have condemned the first six months of data sharing with US terror spooks as an abject failure of data protection. (Source
In terms of the spectrum of information, here, we’re looking at data visualisation. However, most data visualisation that needs to be realised in software takes the form of a Dashboard.
A good dashboard does not just blindly display data. It makes careful decisions about which metrics are important (and how to derive them), plus how to contextualise data so that more complex inter-relationships are both discernable and navigable.
A recent dashboard Sefol have created for one of its projects (PsychePilot, see the screen shot to the left) lets us pack in a wealth of information very efficiently and intuitively.
At the top is an very intuitive display of the state of all of a therapist’s clients, using colour to display trend information, the high/low bar for volitility, and the main body to indicate the open/close state of a client over a two week period. A single click on a client reveals far more detailed information below, at a glance revealing trends, data input points, feedback, and mood bias. A further click on any segment of the mood bias pie chart overlays that specific dataset, and so on. We have found that, without any prompting, users have rapidly discovered, and appreciated, the additional insights which are won.
This is a list of interesting links to data visualisation and dashboards. It will grow occasionally.
Technologies for data visualisation / dashboards :
… what should be a very exciting framework, but it seems to have been in limbo for over a year. No binary release for Flex 4 yet. Axxis
… built on Degrafa, but also, seemingly, sadly, going nowhere.
Although the above technologies seem to be the best open source options out there, they are nevertheless useful for getting good ideas. We recently (in under an hour) remade some of the MicroGraphs idea from BrightPoint
in the standard Flex Charting API (which, having been made part of the OpenSource Adobe offerings, seems to have killed off Degrafa/Axiis).
Some companies to keep an eye on :
Some excellent examples of data visualisation:
A nice example of a timeline from ieee spectrum, a bit more basic, but very very useable :
An old drill-down example – I find this approach potentially interesting for visualising historical datasets http://www.quietlyscheming.com/blog/charts/chart-drilldown-animations/
