  1. SDR I/Q Data Waveform Filtering

    by , December 9th, 2014 at 08:08 PM (Virtual Thoughts for a Virtual World)
    Let's work on the realization that a software defined receiver utilizing sound card sampling presents its I/Q data as a waveform. Now let's say we process the waveform being sampled by the soundcard and passed to the SDR application.

    Unfiltered I/Q data being passed to the SDR application at ~S8 noise level:



    Enabling waveform processing of the I/Q data:

  2. Configure AD authentication with SSL VPN using SOPHOS UTM 9

    by , November 13th, 2014 at 05:31 PM
    VPN configuration is really simple on this device, you can setup a simple local user on the router to allow a VPN connection just by following the link below

    https://www.youtube.com/watch?v=GGt26ZlerpQ

    However this means another username and password a user has to remember so lets make it easier for them to use their AD username and password to log into the VPN. (This is what I had to do to get this working in my environment, ymmv)

  3. Virtualization for the home user

    by , October 31st, 2014 at 01:45 PM
    Virtualization is great for those who want to learn new operating systems, working on certifications, testing out group policies, testing updates/patches, testing software on newer operating systems to name a few. Between all the Linux distros out there and Windows evaluations (yes windows lets you try and operating system for 180 days) unless you have some super old computer, no one has any reason to not try out new things.

    This is just a quick rundown on what options are available ...
  4. SOPHOS UTM 9.2 installation error

    by , October 4th, 2014 at 03:24 PM
    Installing SOPHOS UTM on this mini pc I just bought and I ran into an error while installing the OS. The error was:

    Install.tar could not be found.

    After searching around, supposedly this has something to do with trying to install from a USB drive and the installation process unmounting the usb drive.

    I found this thread about the same issue

  5. Mini computer firewall upgrade post

    by , October 4th, 2014 at 03:00 PM
    So I bite the bullet and purchase this device since my little netgate pfsense firewall wasnt cutting it any more performance wise.

    I was really reluctant to purchase this thing mainly because there is absolutely no information about the hardware such as motherboard, network cards, and how much ram it came with. Well ...

  6. Vmware ESXi 5.1 and ISCSI target issues

    by , September 23rd, 2014 at 08:05 AM
    I am working on an environment where I have 4 Dell R610 servers and a Lenovo/EMC StorCenter px12-350r running software version 4.0.10.30765. All 4 Dell servers have Vmware ESXi 5.1 1483097 installed. I spent most of this past Friday updates all 4 Dell servers to the latest bios/firmware updates (something that is kind of a pain in the ass since I am running ESXi as my operating system. Anyways, the Lenovo Storcenter has about 5 TB of space on it we want to use to present to all 4 Dell servers ...

  7. Pastrami

    by , July 22nd, 2014 at 08:06 PM (A Fish Dinner in Memison)
    I used the corned beef (uncooked) from the previous recipe, and treated it with this adaptation from the Artisan Jewish Deli at Home:
    4-5 lb of corned beef (from previous recipe)
    1/4 cup ground coriander
    2 Tbsp freshly ground black pepper
    2 Tbsp smoked paprika (the Spanish pimenton is good)

    Dry off the surface of the corned beef with paper towels. Evenly rub the mixture on both sides. Preheat the oven to 300 degrees. Place the brisket in a pan, and tightly cover

  8. Home-Made Corned Beef

    by , July 17th, 2014 at 08:43 PM (A Fish Dinner in Memison)
    This is an adaptation of a recipe from Claudia Roden's The Book of Jewish Food. I use a vacuum-sealer rather than a ceramic crock, as it takes less space in the fridge.
    4 1/2 - 5 pounds of beef brisket, preferably flat-cut
    2-4 cloves garlic, chopped finely or pressed in a garlic press
    3 tsp mixed pickling spice (McCormick's is fine)
    2 crumbled bay leaves
    1 tsp crushed black peppercorns
    1/3 cup Demerara sugar (brown would work fine)
    3/4 cup coarse salt (this

  9. Fragrant-and-hot Shrimp

    by , July 7th, 2014 at 08:53 AM (A Fish Dinner in Memison)
    This is a nice recipe, slightly adapted from Fuchsia Dunlop's Revolutionary Chinese Cookbook. Easy to make at short notice, especially if you have a bag of frozen raw shrimp in the freezer. The "chili bean paste" is also known as toban djan. You can use mirin or dry sherry instead of Shaoxing wine.
    Fragrant—and—hot Tiger Prawns (xiang la xia)

    1 lb. tiger prawns or jumbo shrimp, thawed if frozen
    1 tsp. salt
    1 tbsp. Shaoxing wine
    1 tsp. finely chopped fresh

  10. QNAP stupidness with Rsync and delta copy

    by , June 6th, 2014 at 06:45 PM
    A QNAP NAS (TS-212) was purchased for the charity I work with to remotely backup their data in case of an emergency from a Windows box. I have a QNAP at home and remember reading that it supports rsync which is perfect for a free backup solution. I found delta copy and decided to give it a try and boy was this a pain in the ass to get working but here is how I got it going.

    First enable rsync on the QNAP device: Application > backup station > backup server > rsync server ...
