A broadcast join copies the small data to the worker nodes which leads to a highly efficient and super-fast join. When we are joining two datasets and one of the datasets is much smaller than the other (e.g when the small dataset can fit into memory), then we should use a Broadcast Hash Join. The f...
There are two types of scripts we can leverage for running background processing on a specific, regular interval; these are the Scheduled and the Map/Reduce scripts. Note that the Map/Reduce script type is only available in SuiteScript 2.0. The Scheduled script is available for both 1.0 and 2.0. Th...
Often we will want to build custom UI pages in NetSuite; enter the Suitelet. The Suitelet script is designed for building internal, custom UI pages. Pages can be free-form HTML, or they can utilize NetSuite's UI Builder APIs to construct forms that follow NetSuite's look and feel. When it is deploy...
Using the Mass Update script, we can build custom Mass Updates for users to perform. This functions just like a normal Mass Update, where the user selects the type of Mass Update, builds a search that returns the records to update, and then each search result is passed individually into the custom M...
Workflows can be somewhat limited in their functionality; for example, workflows cannot interact with line items. The Workflow Action script type is intended to be invoked by a Workflow to add scripting functionality to accomplish what the workflow itself cannot. Workflow Actions have a single onAc...
Lastly, we have the Bundle Installation script type, which provides several events that allow us to interact with the installation, update, and uninstallation of a particular bundle. This is a rarely-encountered script type, but important to be aware of nonetheless. The Bundle Installation includes...
To add a background-image rule via the CSSOM, first get a reference to the rules of the first stylesheet: var stylesheet = document.styleSheets[0].cssRules; Then, get a reference to the end of the stylesheet: var end = stylesheet.length - 1; Finally, insert a background-image rule for the bo...
This is a step by step guide to set up the automated build process using Jenkins CI for your Android projects.

Describes a dependency relationship between actors, the parent and child releationship. Parent is unique because it has created the child actor, so the parent is responsible for reacting when failures happens in his child. And parent decides which choice needs to be selected. When a parent receives...
There are two type of supervision strategies that we follow to supervise any actor: One-For-One Strategy One-For-All Strategy case object ResumeException extends Exception case object StopException extends Exception case object RestartException extends Exception override v...
Lifecycle Monitoring in Akka is usually referred to as DeathWatch. Monitoring is thus used to tie one actor to another so that it may react to the other actor’s termination, in contrast to supervision which reacts to failure. Monitoring Monitoring is particularly useful if a supervisor ...
PHP lacks a build-in function to encrypt and decrypt large files. openssl_encrypt can be used to encrypt strings, but loading a huge file into memory is a bad idea. So we have to write a userland function doing that. This example uses the symmetric AES-128-CBC algorithm to encrypt smaller chunks of...
Suppose you have two views ViewA and ViewB Instance of ViewB is created inside ViewA, so ViewA can send message to ViewB's instance, but for the reverse to happen we need to implement delegation (so that using delegate ViewB's instance could send message to ViewA) Follow these steps to implement t...

Applications running in non-development environments often require database updates. After using the Add-Migration command to create your database patches there's the need to run the updates on other environments, and then the test environment as well. Challenges commonly faced are: no Visual S...
To get random data from certain collection refer to $sample aggregation. db.emplyees.aggregate({ $sample: { size:1 } }) where size stands for number of items to select.
In order to get the total number of commits that each developer or contributor has made on a repository, you can simply use the git shortlog: git shortlog -s which provides the author names and number of commits by each one. Additionally, if you want to have the results calculated on all branch...
