You can allow role to access some action on resource by: $acl->allow('Administrator', 'products', 'create'); You can deny role to access some action on resource by: $acl->deny('Customer', 'categories', 'create'); You can check if role is allowed to some action on resource by using: $a...

By implementing Phalcon\Acl\RoleAware or Phalcon\Acl\ResourceAware you can use them as objects in Phalcon\Acl\Adapter\Memory::isAllowed(). // Create our class which will be used as roleName class UserRole implements Phalcon\Acl\RoleAware { protected $id; protected $roleName; publ...

Modifying the strings returned by the standard functions getenv(), strerror() and setlocale() is undefined. So, implementations may use static storage for these strings. The getenv() function, C11, §7.22.4.7, 4, says: The getenv function returns a pointer to a string associated with the matched...

To execute a function within a loop in node.js, it's fine to use a for loop for short loops. But the loop is long, using for loop will increase the time of processing which might cause the node process to hang. In such scenarios, you can use: asycn.times function recursiveAction(n, callback) { ...

When we want to handle array of data, its better to use async.each. When we want to perform something with all data & want to get the final callback once everything is done, then this method will be useful. This is handled in parallel way. function createUser(userName, callback) { //creat...

If you have a greedy match as the first quantifier, the whole RE will be greedy, If you have non-greedy match as the first quantifier, the whole RE will be non-greedy. set mydata { Device widget1: port: 156 alias: input2 Device widget2: alias: input1 Device widget3: port: 238 alias...

\m : Beginning of a word. \M : End of a word. \y : Word boundary. \Y : a point that is not a word boundary. \Z : matches end of data. Documentation: re_syntax

# example data DT = data.table(id = c(1,2,2,3,3,3))[, v := LETTERS[.I]][] To deal with "duplicates," combine counting rows in a group and subsetting rows by group. Keep one row per group Aka "drop duplicates" aka "deduplicate" aka "uniquify." unique(DT,...

Literals in RDF may be language tagged strings. These literals have a text part as well as a language tag. For instance, the literal "color"@en has the text part "color" and the language tag "en". In a SPARQL query, use the lang function to get the language of a lite...

The SPARQL function langMatches can be used to compare the language tags of RDF literals in SPARQL queries. The simple equality operator, =, can be used to compare exact string matches, but will not correctly consider regional variants. For instance, the four possible values of ?str in: values ...

First, make sure your app can be backed up in AndroidManifest.xml, i.e. android:allowBackup is not false. Backup command: adb -s <device_id> backup -noapk <sample.package.id> Create a tar with dd command: dd if=backup.ab bs=1 skip=24 | python -c "import zlib,sys;sys.stdout.wri...

You may use this command for listing the files for your own debuggable apk: adb shell run-as <sample.package.id> ls /data/data/sample.package.id/cache And this script for pulling from cache, this copy the content to sdcard first, pull and then remove it at the end: #!/bin/sh adb shell &q...

The familiar curry :: ((a,b) -> c) -> a -> b -> c curry = \f a b -> f (a,b) function can be generalized to tuples of arbitrary arity, for example: curry3 :: ((a, b, c) -> d) -> a -> b -> c -> d curry4 :: ((a, b, c, d) -> e) -> a -> b -> c -> d -&gt...

Template Haskell is enabled by the -XTemplateHaskell GHC extension. This extension enables all the syntactic features further detailed in this section. The full details on Template Haskell are given by the user guide. Splices A splice is a new syntactic entity enabled by Template Haskell, writ...

Often you want to match an expression only in specific places (leaving them untouched in others, that is). Consider the following sentence: An apple a day keeps the doctor away (I eat an apple everyday). Here the "apple" occurs twice which can be solved with so called backtracking cont...

The DATE datatype comprises the date but no time component. Its format is 'YYYY-MM-DD' with a range of '1000-01-01' to '9999-12-31'. The DATETIME type includes the time with a format of 'YYYY-MM-DD HH:MM:SS'. It has a range from '1000-01-01 00:00:00' to '9999-12-31 23:59:59'. The TIMESTAMP type is...

Sometimes a poorly designed 3rd-party library will write unwanted diagnostics to System.out or System.err streams. The recommended solutions to this would be to either find a better library or (in the case of open source) fix the problem and contribute a patch to the developers. If the above solu...

Most PRAGMA statements affect only the current database connection, which means that they have to be re-applied whenever the database has been opened. However, the following PRAGMAs write to the database file, and can be executed at any time (but in some cases, not inside a transaction): applica...
