Probably, one of the most important technologies ever invented for the home is plastic fiber, POF (plastic optical fiber). Unfortunately, it’s mostly unknown to most people, unless you work on the industrial grade networks. POF is basically the same technology as the old S/PDIF optical cable, but with a XXI century technology, from 2Mbps to 100Mbps (1Gbps already in the works, or maybe available) full duplex. What’s the advantage? Size. POF cables are between 1.5 and 2mm wide and extremely flexible. Those compare with Ethernet cables which are around five times thicker and far less flexible. This is not really …

Compared from my old Nokia E61e, it was a world appart: the browser really works! The internet is finally on the subway (private joke, sorry) and not exclusively limited to very basic less than ok mobile sites.

Why on earth would someone want to generate files of random content (not files with random name) ? Well, there is one big reason to do it: generate incompressible files. This seems a small reason, but there are a number os usage scenarios (apart from proving that random content is incompressible), most focus on transmitting files. Although is transparent to most people, but some tools do background compression namely, https, IPSEC and SSL VPNs, etc, and as such, trying to measure real world performance on those require incompressible content. First, how to generate it (assuming you can talk *NIX) ? …
