Four short links: 26 March 2013

An essential reading to inspire your morning
  1. The Obfuscation of Culture — Tumblr and LJ users sep ar ate w ords thr ou gh o dd spacin g in o rde r to fo ol sea rc h en g i nes. Chinese users hide political messages in image attachments to seemingly benign posts on Weibo. General Pretraeus communicated solely through draft mode. 4chan scares away the faint of heart with porn. More technically astute groups communicate through obscure messaging systems.
  2. Towards Deterministic Compressed Sensing — instead of taking lots of data, compressing by throwing some away, can we only take a few samples and reconstruct the original from that? (more mathematically sound than my handwaving explanation). See also Compressed sensing and big datafrom the Practical Quant.
  3. Microsoft is indeed working on a modern File Manager app for Windows Blue – Yesterday, we reported the possibility of Microsoft working on a File Manager app for the next update to Windows 8. The references to this new File Manager app was seen in the leaked Windows Blue build 9364. Now, an image has surfaced showcasing the File Manager app.
  4. It’s Time to Retire ‘Crap Circles’ – Every time I encounter a crap circle my heart sinks. I first wrote about these contemptible “information” graphics in HBR in 2005, and since then they’ve only seemed to multiply. You know what these are — you may have even used them — though you may not have had a name for them. I aim to change that. These pernicious circles-and-arrows diagrams infest PowerPoint and other business presentations, purporting to clarify an idea while actually obscuring it.
