resolving proxy problems using command line tools eg wget,apt-get etc on ubuntu lucid 10.04

anyone who uses ubuntu lucid 10.04(behind proxy) would have faced
issues connecting to internet either in download(using wget)
or during package installation using apt-get().

This is because even though you have set proxy using export http_proxy=<ur-proxy-ip>:<port>
or configured the same in system wide network settings,
the actual http request doesn't seem to go through the proxy(atleast from the logs).

Actually the real culprit is the env variable no_proxy :)
if you print all the environment variables you will find that
the environment variable no_proxy has a trailing comma which it should not.

so the solution to the problem is to add the following line to your bashrc file.
export no_proxy=$(echo $no_proxy | sed 's/,$//')

once this is done you should be able to use wget / apt-get tool etc.....without any issues :)

Getting and Setting Microphone Gain or Microphone Boost on Windows 7 / 8 Programmatically

After hours of searching the net I have finally figured out a way to programmatically get and set the microphone gain (boost) value. The code mentioned below can be built on VS and does the job of setting gain value. #include "stdafx.h" #include <mmdeviceapi.h> #include <endpointvolume.h> #include <Functiondiscoverykeys_devpkey.h> #include "Audioclient.h" #include "comutil.h" #define EXIT_ON_ERROR(hres)   if (FAILED(hres)) { goto Exit; } #define SAFE_RELEASE(punk)   if ((punk) != NULL)  { (punk)->Release(); (punk) = NULL; } HRESULT getMicrophoneBoostVolumeLevel(IMMDevice *pEndptDev, IAudioVolumeLevel** ppVolumeLevel) { HRESULT hr = S_OK; DataFlow flow; IDeviceTopology *pDeviceTopology = NULL; IConnector *pConnFrom = NULL; IConnector *pConnTo = NULL; IPart *pPartPrev = NULL; IPart *pPartNext = NULL; *ppVolumeLevel = NULL; wchar_t microphoneBoostName[] = L"Microphone Boost";//if your system ...

Simple example of strong and weak pointers on Android using RefBase class

Here is a simple example explaining the usage of strong and weak pointers using android's RefBase class and the Android.mk to compile the same. Its a modified version of code written by Daniel in the following link. http://himmele.blogspot.com/2012/03/androids-c-reference-counting.html strong_pointer.cpp file:  #include <stdio.h> #include "utils/RefBase.h" namespace android {  class RefTest : public RefBase { public:     RefTest(int32_t id) : mID(id) {         printf("RefTest ctor: %d\n", mID);     }     virtual ~RefTest() {         printf("RefTest dtor: %d\n", mID);     }     int32_t id() const {         return mID;     } private:     int32_t mID; }; int strong_pointer() {     sp<RefTest> ref1 = new RefTest(1);     sp<RefTest> ref5;   ...

Acts Automation Framework For Android

1. Introduction The Android Comms Test Suite, is a lightweight Python-based automation tool set that is used to perform automated testing of current and upcoming Android devices. It provides a simple execution interface; a set of pluggable libraries for accessing commercially available devices, Android devices, and a collection of utility functions to further ease test development. It is an ideal desktop tool for a wireless stack developer or integrator whether exercising a new code path, performing sanity testing, or running extended regression test suites. Included in the tests/google directory are a bundle of tests, many of which can be run with as little as one or two Android devices with wifi, cellular, or bluetooth connectivity, including: 1. Wifi tests for access point interopability, enterprise server integration, WiFi scanning, WiFi auto join, and round trip time. 2. Bluetooth tests for low energy, GATT, SPP, and bonding. 3. Cellular tests for circuit switch and...
