Android now supports devices with 512MB of RAM. This documentation is intended to help OEMs optimize and configure Android 4.4 for low-memory devices. Several of these optimizations are generic enough that they can be applied to previous releases as well. Enable Low Ram Device flag We are introduc...

The CPU governor itself is just 1 C file, which is located in kernel_source/drivers/cpufreq/, for example: cpufreq_smartass2.c. You are responsible yourself for find the governor (look in an existing kernel repo for your device) But in order to successfully call and compile this file into your ke...

DispatchSemaphore provides an efficient implementation of a traditional counting semaphore, which can be used to control access to a resource across multiple execution contexts. A scenario for when to use a semaphore could be if you are doing some file reading/writing, if multiple tasks are t...

There are two main functions in Redis (HSET and HMSET) for adding fields to a hash key. Both functions are available in redis-py. Using HSET: import redis r = redis.StrictRedis(host='myserver', port=6379, db=0) r.hset('my_key', 'field0', 'value0') Using HMSET: import redis r = redis.St...

Redis allows you to add items to either the right or the left of a list. If I was working with a list, my_list and I wanted to prepend 3 to the list, I could do that using the Redis LPUSH command: LPUSH my_list 3 If I wanted to append 3 to my_list, I would instead use the RPUSH command: RPUSH ...

Redis provides the LPOP and RPOP commands as a counterpart to the LPUSH and RPUSH commands for fetching data items. If I was working with a list my_list that had several data items in it already, I can get the first item in the list using the LPOP command: LPOP my_list The result of this comman...

The size of a set can be determined using the SCARD command. SCARD will return the cardinality of a set or the number of members in the set. For example, if I had a Redis set my_set stored in the database that looked like (Apple, Orange, Banana), I could get the size using the following code: SCA...

The basic Redis command for adding an item to a set is SADD. It takes a key and one or more members and adds them to the set stored at the given key. For example, lets say that I wanted to create a set with the items apple, pear and banana. I could execute either of the following: SADD fruit app...

Redis supplies the SISMEMBER command to test if a particular item is already a member of a set. Using the SISMEMBER command I can test and see if apple is already a member of my fruit set. If I construct my fruit set from the previous example, I can check and see if it contains apple using the fol...

Redis provides the ZADD command to add items to a sorted set. The basic form of the ZADD command is to specify the set, the item to add and it's score. For example, if I wanted to construct an ordered set of my favorite food (from least to most), I could use either of: zadd favs 1 apple zadd fav...

The size of a Redis list can be deterimed using the LLEN command. If I have a four element list stored at the key my_list, I can get the size using: LLEN my_list which will return 4. If a user specifies a key that doesn't exist to LLEN, it will return a zero, but if a key is used that points t...

Redis provides seven different operations for working with scripts: Eval operations (EVAL, EVALSHA) SCRIPT operations (DEBUG, EXISTS, FLUSH, KILL, LOAD) The EVAL command evaluates a script provided as a string argument to the server. Scripts can access the specified Redis keys named as argum...

Be aware that the WebBrowser control is not sympathetic to your XAML definition, and renders itself over the top of other things. For example, if you put it inside a BusyIndicator that has been marked as being busy, it will still render itself over the top of that control. The solution is to bind th...
