How to Sign Steam Dylib for Mac OS X in XCode

Clear Application Data with ADB at the command line

You can use package manager (pm) to clear data for installed apps (same as pressing the 'clear data' button in the app settings on your device).

Run this adb command, replacing 'com.company.games.game' with your package name from AndroidManfiest.xml

adb shell pm clear com.company.games.game

This method depends on the 'pm' tool being resident on the Android device, which is not always the case.

NullPointerException at android.widget.ArrayAdapter.createViewFromResource

Crashes while using code like this:

AlertDialog.Builder builder = new AlertDialog.Builder(StatusMenuConflicts.this);

builder.setTitle("Star Traders RPG");

builder.setIcon(R.drawable.icon);

final String[] items = new String[6];

items[0] = getString(R.string.status);

The stack trace won't contain your code.

The problem is that Android is looking for 6 elements in the Array you're passing in, but you've only defined one. Set the length of you String[] correctly and the code will work.

Interviews -- Reverse Singly Linked List, C++

Just seriously struggled through an interview on the phone. It's always the simple programming problems that seem the hardest when someone is watching you do it.

The question was "Write a simple function to reverse a linked list" and I couldn't get it right until 3 minutes after the interview was over. Every. Single. Time.

So here is the code I ended up with, given this basic Linked list.

struct List {
   int value;
   mySingleLinked* next;
};

Seems simple, right? See the comments ;)

// arg. i'm an idiot
List reverseLinkedList(List* head) {
    List *tempList, *nextList;

tempList = 0;
nextList = 0;

while (head != 0)
{
nextList = head->next;
head->next = tempList;
tempList = head;
head = nextList;
}
return tempList;
}

Quick AES Encrypt String with Botan C++

AutoSeeded_RNG rng;
SymmetricKey key(rng, 16); // a random 128-bit key
InitializationVector iv(rng, 16); // a random 128-bit IV
Pipe pipe(get_cipher("AES-128/CBC", key, iv, ENCRYPTION), new Hex_Encoder);
pipe.process_msg("secrets");
std::string m1 = pipe.read_all_as_string(0);
Pipe pipe2(new Hex_Decoder, get_cipher("AES-128/CBC", key, iv, DECRYPTION));
pipe2.process_msg(m1.c_str());
std::string m2 = pipe2.read_all_as_string(0);

How to Screen Record Android Video

Launch into the command line with your Android 4.4 device connected to your computer and enter the command to record your screen:

adb shell screenrecord /sdcard/demo.mp4

You can further customize the speed at which it captures video, the length of time it records (the default duration is 3-minutes) and the size of the video in terms of resolution.

Another example of a command to record a video would be:

adb shell screenrecord --bit-rate 8000000 --time-limit 30 /sdcard/kitkat.mp4

The above command would record at 8Mbps, instead of the default 4Mbps, for a duration of 30-seconds and save it to the SD Card on your device with the name of KitKat. You can find a full list of commands for screenrecord here on the Android Developer Site.
