  • Only f/5.6 for auto-focus

    People keep asking a simple question: “why do my expensive camera fail to auto-focus when I plug my tele-lens into a 2x converter?”. Unfortunately, the answer is pretty simple. Most auto-focus cameras (digital or not) have a AF sensor limited to f/5.6 detection. If your lens is not opening more than that, the AF is…

  • Inkjet paper has a surface: Is microporous best?

    All inkjet papers were not born equal. For example, their surface can be varying a lot from one paper to the next. Maybe, you thought that the only difference was in the weight of the paper, whether it was glossy and its price. Oh boy! Were you wrong… As a matter of fact, paper manufacturers…

  • Nuclear war in Iran in 2006? It’s gonna flash!

    In a private circle, I had made the prevision that the United States of America would initiate a military action against Iran in 2005. Time proved I was a poor prophet.

  • This Boring Headline Is Written for Google

    That is exactly the title of an article just published in the New York Times and explaining how online publication had to adapt itself to search engines, their literal-minded approach to text and the impossibility to use nice, intelligent, witty, humorous, sarcastic titles.

  • RIAA says “Jail the ghost!”

    Gertrude Walton is probably not the last person and certainly not the first to be facing the wrath of the RIAA while this association fights against music pirates. She is a bit unusual in the sense that she is an 80-year old Granny and stands accused of downloading 700 songs off peer-to-peer (P2P) networks under…

  • Portable phones allowed in plane! more or less…

    It’s been years that flight attendants repeat to bored flight passengers that portable phones should be switched off during the flight because they may interfere with navigation equipment of the plane. Also, it’s been years that Boeing and Airbus tested this hypothesis and found no risk at all. But nobody wants to take the risk…
