SDR-radio.com and SDR# do not recognize RTL based tuner.

That story begins when I decided to start SDR radio on my laptop. I bought DVB-T USB tuner, based on RTL2832U chip, downloaded software and start playing. Zadig driver installed without any problems, but sdr software was unable to find my tuner.
I have tried different versions of zadig drivers, all of them installed with succes. Different versions of sdr software and different .dll's, but result was always the same - when I tried to start sdr software it did not saw tuner.

After some research and internet browsing I found that problem relays to libusbx, and NEC/Renesas USB 3.0 chip users should upgrade their drivers to version 2.1.16.0 or later. There is a bug in older versions that prevents libusbx from accessing devices. Unfortunatelly my laptop (HP EliteBook 8460p) has that USB 3.0 chip.

Problem was resolved by downloading new driver from HP. After installation I tried to start SDR#, but again with no luck. Though driver's installer reported, that installation was successful, but after looking in driver's properties I recognized that old drivers still in use. So I manually updated driver (Device manager -> Update Driver Software... -> Browse my computer for driver software -> Choose folder with drivers files). After that software was able to detect tuner.

Hope it will help someone to avoid dificulties with configuration.

How to install .NET Framework 3.5 on Windows Server 2012

​
The problem was that the .NET Framework 3.5 was a requirement, and I was unable to install it from the Server Manager.This is the problem I ran in to when trying to add the feature:
“Do you want to specify an alternate source path? One or more installation selections are missing source files…”

Apparently, there’s a bug in Windows Server 2012 when trying to add the .NET Framework 3.5 from Server Manager. In order to get it to work, I had to enable the feature via the Command Prompt.
This is the command that I had to type:
dism /online /enable-feature /featurename:NetFX3 /all /Source:d:\sources\sxs /LimitAccess
Note: Source should be the Windows installation disc. In my case, this was located on D:

After running this command, .NET Framework 3.5 was enabled and I was able to install SQL Server 2008 R2

Configuring postfix to forward all email to a smtp gateway

Introduction

Suppose you want all your web servers to locally send all email (maybe from your contact forms, or whatever) to a real smtp gateway. If you're running postfix as your mta, this is quite easily to achieve.

Configuration

In your main.cf file (usually /etc/postfix/main.cf or /usr/local/etc/postfix/main.cf), specify your transport maps:

1. transport_maps =  hash:/etc/postfix/transport  

And in your transport file (usually /etc/postfix/transport or /usr/local/etc/postfix/transport), specify your gateways per domain. This allows you to specify with regular expressions which emails go where. In this case, an asterisk specifies every domain (the transport file allows very complex setups, this is of course an extreme and trivial example):

1. *              smtp:myotherhost.com  

Then invoke postmap to regenerate the transports db, and reload postfix:

1. # postmap hash:/etc/postfix/transport  
2. # postfix reload  

That should do it. All email generated in this host should now be forwarded to the smtp gateway. Remember to configure your smtp gateway to accept mail from all the hosts that will forward emails to it.
