  • Recuva: Free Recovery software for Windows….

    Lost a couple of files today by mistake (that’s what I get for using Synergy keyboard/mouse sharing application to run in windows)…..anyways, after a bit of googling I came across a very nice and simple recovery tool….Recuva. This one even recovers stuff that’s been deleted from the Recycle Bin (which was my case/mistake). Nice….and did […]

  • JetBytes: On-the-fly file transfer……

    Neat idea…..You all know about sites where you can upload a large file, for your friends to download. It’s simple, but what if you don’t want to store the file somewhere.

Through trial and error we found out that the default umask (under OSX Server) for sftp uploaded files are 0033 (ie: rwxr–r–) and directories are 0022 […]

  • SONET and Telecomm buzzwords explained….

    So this is just a short tutorial, so I don’t have to repeat this to every person who asks about the difference between T and E circuits. Here is the whole thing (more or less), (hopefully) once and for all. It all starts with the Nyquist’s Theorem and Pulse Code Modulation. PCM is the way […]

  • Make your browser faster (safer) with OpenDNS

    Okay, so this worked for me. I don’t promise that it will do the same for you. Let me explain, my ISP (who shall remain nameless) is very good (good uptime, unlimited, good throughput), but for some reason has horrible DNS servers. I normally try not to use their servers and instead use either my […]
