    Don't be too discouraged by job postings requiring an EE or CE degree. At my last two companies (a network gear vendor and a hosted VoIP provider), our postings stated EE/CE was pr…

    If you are on a system that doesn't have tshark, tcpdump provides the same functionality via the -C -W flags. e.g. -C 100 -W 200 -w somefile will get you the same circular ring of …

    Nothing sexual was implied by my comment, though I do see how the word is problematic. "Seminal" is so frequently used to describe early and influential bands in punk, including Ri…

    The trouble is, you'd have an easier time selling the scraps of your lunch than you would a home in Vegas. Condos that were going for $180K in my old neighborhood are now at $30K a…
