New Take on Ubicomp, Language Insight, Sexy Viz, and iPad Usability
- People are Walking Architecture — presentation by Matt Jones of BERG, taking a new lens to this AR/ubicomp/whatever-it-is-today world. “[Mobile phones are] a whole toy box full of playful, inventive strategies for exploring cities ….”
- Lexicalist — insight into geographic and age distribution of language use, based on Twitter data. (via Language Log)
- Advanced Visualization Techniques — nice overview of some non-standard visualization techniques. Short shameful confession: I love polar dendrograms with a passion. These techniques are to visualizers as algorithms and data structures to programmers: each is used in specific circumstances and compromises some things to gain in others. (via Flowing Data)
- iPad Usability Report (Nielsen-Norman Group) — 93-page report based on user studies. The iPad etched-screen aesthetic does look good. No visual distractions or nerdy buttons. The penalty for this beauty is the re-emergence of a usability problem we haven’t seen since the mid-1990s: Users don’t know where they can click. For the last 15 years of Web usability research, the main problems have been that users don’t know where to go or which option to choose — not that they don’t even know which options exist. With iPad UIs, we’re back to this square one. (via Andrew Savikas)
Leaky Phones, Clustering Tweets, CS Unplugged, and Margaret Atwood on Twitter
- Researchers Show How To Use Mobiles to Spy on People — Using information from the GSM network they could identify a mobile phone user’s location, and they showed how they could easily create dossiers on people’s lives and their behavior and business dealings. They also demonstrated how they were able to identify a government contractor for the US Department of Homeland Security through analyzing phone numbers and caller IDs. [...] The researchers have not released details of the tools they developed, and have alerted the major GSM carriers about their results. Bailey said the carriers were “very concerned,” but mitigating these sorts of attacks would not be easy. In the meantime there is little mobile phone users can do to protect themselves short of turning off their phones. Oh joy. (via Roger Dennis)
- A Torrent of Tweets: Managing Information Overload in Online Social Streams (PDF) — PARC and MIT built a Twitter client that clusters messages in a useful way. Publicly accessible client due in summer.
- Interview with Tim Bell (MP3) — author of Computer Science Unplugged, which teaches computational thinking in a fashion that can have five year olds understanding error correction codes, and one of the people behind a new high-school curriculum for CS in New Zealand.
- How I Learned to Love Twitter (Guardian) — fascinating piece from writer Margaret Atwood. The Twittersphere is an odd and uncanny place. It’s something like having fairies at the bottom of your garden is one of my favourite things that’s ever been written about Twitter but the whole article is delightfully written.
Against Open Data, Singalong Selection, Library Release, and Twitter Analysis
- Aren’t You Being a Little Hasty in Making This Data Free? — very nice deconstruction of a letter sent by ESRI and competitors to the British Government, alarmed at the announcement that various small- and mid-sized datasets would no longer be charged for. In short, companies that make money reselling datasets hate the idea of free datasets. The arguments against charging are that the cost of gating access exceeds revenue and that open access maximises economic gain. (via glynmoody on Twitter)
- User Assisted Audio Selection — amazing movie that lets you sing or hum along with a piece of music to pull them out of the background music. The researcher, Paris Smaragdis has a done lot of other nifty audio work. (via waxpancake on Twitter)
- Cologne-based Libraries Release 5.4M Bibliographic Records to CC0 — I see resonance here with the Cologne Archives disaster last year, where the building collapsed and 18km of shelves covering over 2000 years of municipal history were lost. When you have digital heritage, embrace the ease of copying and spread those bits as far and wide as you can. Hoarding bits comes with a risk of a digital Cologne disaster, where one calamity deletes your collection. (via glynmoody on Twitter)
- ThinkTank — web app that lets you analyse your tweets, break down responses to queries, and archive your Twitter experience. Built by Expert Labs.
Open Source Design, Interesting NoSQL Use, Copyright Documentary, Location Intelligence
- Open Source Enters The World of Atoms — an academic statistical analysis of open design. We indicated that, in open design communities, tangible objects can be developed in very similar fashion to software; one could even say that people treat a design as source code to a physical object and change the object via changing the source.
- Why I Like Redis (Simon Willison) — coherent explanation of why Simon likes and uses a particular nosql system. I can run a long running batch job in one Python interpreter (say loading a few million lines of CSV in to a Redis key/value lookup table) and run another interpreter to play with the data that’s already been collected, even as the first process is streaming data in. I can quit and restart my interpreters without losing any data. And because Redis semantics map closely to Python native data types, I don’t have to think for more than a few seconds about how I’m going to represent my data.
- © kiwiright (Vimeo) — short documentary about copyright, made to raise awareness of the issues in New Zealand. (just as applicable to the rest of the world)
- Your Movements Speak For Themselves (Jeff Jonas) — Mobile devices in America are generating something like 600 billion geo-spatially tagged transactions per day. Every call, text message, email and data transfer handled by your mobile device creates a transaction with your space-time coordinate (to roughly 60 meters accuracy if there are three cell towers in range), whether you have GPS or not. Got a Blackberry? Every few minutes, it sends a heartbeat, creating a transaction whether you are using the phone or not. If the device is GPS-enabled and you’re using a location-based service your location is accurate to somewhere between 10 and 30 meters. Using Wi-Fi? It is accurate below10 meters. A thought-provoking roundup of the information leakage with modern locative systems. (via TomC on Twitter)
Electronics Hacking FAQs, Speech-To-Text Democracy, Open Source Column Database, Massive Online Analysis
- ChipHacker — collaborative FAQ site for electronics hacking. Based on the same StackExchange software as RedMonk’s FOSS FAQ for open source software.
- Democracy Live — BBC launch searchable coverage of parliamentary discussion, using speech-to-text. One aspect we’re particularly proud of is that we’ve managed to deliver good results for speech-to-text in Welsh, which, we’re told, is unique. I think of this as the start of a They Work For You for video coverage. I’d love to be able to scale this to local government coverage, which is disappearing as local newspapers turn into delivery mechanisms for real estate advertisements.
- InfiniDB: Open Source Column Database — hooks into MySQL, uses MySQL for SQL parsing, security, etc. The commercial enterprise version has multi-server support (parallel scale-out). (via Brian Aker)
- Massive Online Analysis — MOA is a framework for data stream mining. Includes tools for evaluation and a collection of machine learning algorithms. Related to the WEKA project, also written in Java, while scaling to more demanding problems. . (via joshua on Delicious)
