Complete Guide To Javascript Setinterval

Introduction to JavaScript setInterval

The following article provides an outline for JavaScript setInterval. In Javascript, the Window or Worker interface provides timer events and methods. One of these interfaces’ most essential methods is the setInterval() method. This method allows us to perform or execute a certain code snippet repetitively and after some fixed time interval. It returns a numeric id that uniquely represents the created interval and can be further used to destroy this event or stop repetitive execution with the help of the clearInterval() method and the interval id.WindowOrWorkerGlobalScope mixin provides us with timer-related events. One of them is the setInterval() method.

Start Your Free Software Development Course

Syntax of JavaScript setInterval

Given below is the syntax mentioned:

var intervalIdentifier = scope.setInterval(function, delayTime, [arguments1, arguments2, ...]); var intervalIdentifier = scope.setInterval(code, delayTime);

Explanation:

Intervalidentifier: The returned value from the setInterval method of WindowOrWorkerGlobalScope scope is a numeric identifier unique for every interval created in the session. It is always non-zero integers and can be further used to stop the execution of interval using the clearInterval() method, which is again, in turn, a method of WindowOrWorkerGlobalScope interface that helps in clearing the interval.

Function: This function holds the code snippet you aim to execute repeatedly once you set the interval. By default, we assume this function neither accepts any parameters nor returns any value.

DelayTime: The time in milliseconds(1 second = 1000 milliseconds) specifies the time interval between the repetitive call to the function.

Code: A string can be supplied optionally instead of the function call. The system compiles and executes this string each time the setInterval’s delay time ends, repeating this process. It is generally not used for security reasons.

Arguments: You can pass these optional parameters to your function call when needed.

Examples of JavaScript setInterval

Given below are the examples of JavaScript setInterval:

Example #1

Code:

var intervalIdentifier; function switchColour() { intervalIdentifier = setInterval(blinkString, 500); } function blinkString() { var divisionObject = document.getElementById(‘coloredDivision’); divisionObject.style.color = divisionObject.style.color == ‘red’ ? ‘blue’ : ‘red’; } function stopBlinking() { clearInterval(intervalIdentifier); }

Output:

Example #2

Suppose you want to display the countdown for a certain event and display the message after a specific time.

Code:

var startCounter=10; var countdownId = setInterval(newYearCounter ,1000); function newYearCounter() { document.getElementById(“displayCountdown”).innerHTML = startCounter + ” Seconds Left!”; startCounter -=1; if(startCounter===0){ document.getElementById(“displayCountdown”).innerHTML = “Happy New Year!”; clearInterval(countdownId); } }

Output:

Passing Parameters to the Called Function

There might come a situation in a real-time environment where you must pass the arguments to the function being called. We can optionally pass parameters to the function, which we call repetitively for execution in the setInterval() method.

Code:

var intervalId; var counter; function beginDisplayFunc() { intervalId = setInterval(function(){ displayMessage(“Good”, “Morning”); }, 2000); counter=0; } function displayMessage(param1, param2) { counter++; document.getElementById(“sample1″).innerHTML += counter + ” “; document.getElementById(“sample2”).innerHTML = “Parameters passed to displayMessage(): } function stopDisplayFunc() { clearInterval(intervalId); }

Callback Arguments

Some versions of some browsers do not support passing arguments to the function called in the setInterval method.

For example, Internet Explorer’s version 9 and previous versions do not support passing such arguments. In this case, we must make special efforts or consider these exceptions while coding for the setInterval() method. We can achieve passing arguments to setInterval() for non-compatible browsers in three ways.

Setting isPolyfill property of setInterval() method to true.

We can use an anonymous calling function to call a function without a parameter in the setInterval() method, which will, in turn, call a function; with we can do so in the following way:

var argumentPassingIntervalId = setInterval(function() { mainFunction('param1', 'param2', 'param3'); }, 3000);

In this case, we write and call the main function, which passes the arguments, inside the function that we pass to the setInterval() method.

Another way of achieving this is by using the bind function, which can be used in the following way – var myIntId = setInterval(function(param1) {}.bind(undefined, 20), 3000);

Nested setInterval() Events

It is possible that we can begin a certain event of setInterval() inside the function, which is, in turn, called by another setInterval() methods call. This is called the nesting of events. Browsers allow the nesting of events for, at most, 5 levels. Using the setInterval() method inside a 5-level nested setInterval enforces a minimum delay time restriction of four milliseconds. If we forcefully specify less than four milliseconds of value browser will internally pin it to 4 milliseconds.

Compatible browsers for this method usage are:

Chrome 30.0

Internet Explorer 0

Firefox 1.0

Edge

Opera 0

Safari 0

Conclusion – JavaScript setInterval

In this way, we can use the setInterval() method of the window scope object for repetitively executing a certain functionality after a specific time interval. However, we must consider certain issues and limitations of this method, like browser compatibility and nesting of such events.

A Complete Guide To Tensorboard

Introduction

As data volume increases, deep learning techniques tend to perform better as compared to the classic methods. But, it comes with the drawback of complexity and thereby reduction in interpretability of the algorithm. The complexity also creates issues for hyperparameter tuning.

But what if there is a solution? 

The solution is TENSORBOARD. It is a visualization extension created by the TensorFlow team to decrease the complexity of neural networks. Various types of graphs can be created using it. A few of those are Accuracy, Error, weight distributions, etc.

Components of Tensorboard

There are five components to it, namely:

1) Scalars: It is very difficult to look at the accuracy and error for each epoch given the number of the epoch is very large and there are chances of ending up getting stuck in local minima instead of the global ones. These two problems can be solved using this section. It displays both accuracy and error graph wrt epoch.

2) Graphs: This section visualizes the “model.summary()” results. In other words, it makes the architecture of neural networks more appealing. This eases the process of architecture understanding easier.

3) Distributions: In general, neural networks contain a lot of layers and every layer is composed of numerous biases and weights. This section represents the distribution of these hyperparameters.

4) Histograms: Consists of the histogram of these hyperparameters.

5) Time-Series: Consists of the over-time values for the same. These sections are useful in controlling the hyperparameters by analyzing their trends.

Code

There are two ways to publish tensorboards: localhost(powered by terminal) and within jupyter notebook. The below code looks at both scenarios. For this exercise, we will be taking a very famous inbuilt dataset: mnist.

Step 1: import the TensorFlow library. import tensorflow as tf Step 2: Load data and divide it into train and test mnist = tf.keras.datasets.mnist (x_train, y_train), (x_test, y_test) = mnist.load_data() x_train, x_test = x_train / 255.0, x_test / 255.0 Step 3: Create model architecture model = tf.keras.models.Sequential([ tf.keras.layers.Flatten(input_shape=(28, 28)), tf.keras.layers.Dense(128, activation='relu'), tf.keras.layers.Dense(56, activation='relu'), tf.keras.layers.Dropout(0.2), tf.keras.layers.Dense(32, activation='relu'), tf.keras.layers.Dense(10) ]) Step 4: Compile model

loss=loss_fn, metrics=[‘accuracy’])

Step 5(important): Create a callback function. A callback function periodically(epochs) saves the model and the results(error, accuracy, bias, weights, etc) of the model. This is required as the graphs are a result of these values wrt every epoch. tf_callbacks = tf.keras.callbacks.TensorBoard(log_dir = "logs/fit" , histogram_freq = 1) Step 6(important): Model fitting (remember to pass callback function) model.fit(x_train, y_train, epochs=200, callbacks = tf_callbacks)

The results of these epochs are very difficult to remember.

Step 7: Create tensorboard using the following: %reload_ext tensorboard %tensorboard --logdir logs/fit

Comparing optimizers using Tensorboard visualization

The performance of the two optimizers can also be compared through this. In order to do so, create two directories “logs/optimizer1″(step 5) and “logs/optimizer2” and use these directories to store the results of the respective optimizer(step 4 to change the optimizer and step 6 to execute that) and then launch the tensorboard using step 7.

Final Note: 

Thanks for reading this blog, it requires a lot of patience to learn TensorFlow and its associated packages on your own. Kudos to you!

Demystifying Nosql: Your Complete Interview Guide

This article was published as a part of the Data Science Blogathon.

Introduction

In data science, learning about database

He has two things to know. Learn as much as possible about database administration and understand how to approach it efficiently. Trust me; you’ll come a long way in data science. Data engineers must work with all databases, especially S stumble is when we need to move to a NoSQL database. It can be a little confusing at first. Getting started is always the hardest step.

(Source: src)

This article describes the essential differences between these two types of databases to clear this roadblock. This will give you two overviews and make it easier to start your journey. Let’s start

Interview Question on NoSQL 1. What do you understand and know about NoSQL in databases?

Contrary to the literal translation of the meaning, NoSQL stands for “Not Only SQL.” It is a new way of thinking about databases, which can handle many structured, semi-structured, and complicated data. It refers to various database technologies created in response to increased data being saved about individuals, things, and goods. Performance and processing requirements, as well as the frequency of access to this data. Contrarily, relational databases were not created to handle the size and agility issues that plague modern applications, nor were they meant to benefit from the affordable storage and processing power available today. So the main target of NoSQL is to create an alternate database in SQL -where textual data can be stored easily in a less-structured manner.

Unlike RDBMS, NoSQL is far more easily scalable and provides superior performance. Additionally, it helps address the issues that RDBMS failed to address:

NoSQL is capable of handling large amounts of structured, semi-structured, and unstructured data

OOPs can easily be used and integrated with NoSQL

Provides efficient scale-out architectures while RDBMS mainly operates on monolithic architectures

It provides agile sprints, and the iterations are quick because the in-memory caching option is available to increase the performance of queries.

It provides good support for Analytic tools on top of Bigdata

It is capable of being hosted on cheaper hardware machines

(Source: src)

3. What are the different types of databases available under NoSQL?

NoSQL databases come in the following types:

Document Oriented DB – One of the characteristics of the NoSQL database is this. The data should be stored without schema. As a result, scalability will be higher, and JavaScript object notation will be used. The job will be completed more quickly and for less money. Example -MongoDB

Key-Value Stores – The data is often stored in tables in the RDBMS database, while hash tables are used in NoSQL to store data. Each of these tables has its own identity. Working with a key-value store is preferable to utilizing joins if you are looking for data. This key value will retrieve data from the hash table more quickly. Examples – Riak, Voldemort, and Redis.

Graph DB – A graph database is one of the most crucial databases in NoSQL. It is primarily tailored for navigating and storing data relationships. Edges will contain data relationships, and the idea is entity information. Banks, social media, new channels, etc., use this database. Example –  Neo4J and HyperGraphDB.

Column Oriented Stores- This gives NoSQL much more flexibility. Keyspace is a concept in column databases that functions somewhat similarly to a relational model’s schema. All column families are contained in this keyspace, which in turn comprises rows and columns. It takes a little while to get your head around, but it’s not too difficult. Example -Cassandra and HBase.

The different types of databases in NoSQL (Source: src)

4. What is the difference between Vertical and Horizontal Databases?

Vertical Database

Horizontal Database

The physical layout of data is column by column. Vertical ScalingScalingus be added, thereby adding more power to the PC. The physical layout of data is row by row. Thus horizontal scaling is achieved, thereby adding more equipment.

All data is stored in a single node. Only part data is stored in all nodes.

Multi-core scaling will be done. Single-core scaling done.

Example – Amazon Cloud Example – MongoDB

 5. What do you understand by Polyglot Persistence in NoSQL?

Polyglot Persistence suggests that database engineers/architects should determine how they want to manipulate the data and then choose the database technology that best suits their needs. This approach solves data storage efficiency problems, simplifies operations, and eliminates fragmentation.

Schematic representation of Polyglot Persistence. Note how data is fed from different sources (Source: src)

6. When should NoSQL be used over RDBMS?

You can utilize NoSQL if you seek key-value stores with extremely high-performance levels because ACID transactions are used in relational databases. The schema-based process will slow down the database performance once we employ this transaction.

Possible scenarios of potential usage of NoSQL are:

In situations of the need for multiple JOIN queries

For high-traffic websites

While using denormalized data

7. Explain the CAP theorem in NoSQL.

It is the most reliable of the three guarantees for a NoSQL database. CAP is the fundamental value of consistency, availability, and partition tolerance. The nodes will be working in tandem in the network. As a result, the entire functioning of the database will work faster.

8. What is understood by Database Sharding in NoSQL?

Database sharding in NoSQL refers to splitting the database according to NoSQL time-appropriate patterns. Data can be stored by sharding over numerous, possibly independent servers worldwide. A database administrator can readily retrieve this data from anywhere in the world with excellent data speed characteristics.

Schematic representation of Data Sharding in NoSQL (Source: src)

9. What are the ways to track data record relations in NoSQL?

The possible steps are as follows:

Embed all data into any user-object

Create the user-id credential

Following these three steps will lead to the desired information retrieval.

10. Explain the BASE Characteristic of NoSQL.

The BASE model, which is a softer approach, is used by NoSQL. The BASE stands for Basically Available, Soft state, Eventual consistency.

Available: Assures the data’s accessibility. Any inquiry will receive a response (it can be a failure too).

Soft state: Over time, the system’s state might change.

Eventually Consistent – It assumes that once it stops accepting input, the system will finally achieve consistency.

NoSQL databases sacrifice the A, C, and D requirements for greater scalability.

Conclusion

Throughout the ten questions, we have covered the essential concepts of NoSQL as a DBMS. Key takeaways from today’s blog include –

The general idea of NoSQL and why it originated and came into popularity

The key features and different types of databases in NoSQL

Key concepts like Polyglot Persistence, CAP Theorem, Database Sharding

When you should be using NoSQL over the existing RDBMS

The BASE characteristics of NoSQL over ACID characteristics of RDMBS

If thoroughly well versed with the above ideas and questions will surely give you an edge in the interview. Hope you liked today’s topic of discussion and you managed to add new concepts to your existing knowledge. Wishing you great luck with your future goals and aspirations!

A Complete Guide To The Laravel Orm

Introduction to Laravel ORM

In Laravel we have ORM which basically stands for Objects relation model and Laravel include Eloquent, which helps us to interact with the database. Here ORM is basically related to the database side, where it helps us to interact with it, by that, we can perform delete, insert, update and other operations what is generally do it helps us to map our database entity with the corresponding code model. Every table in the database associates with the model, in order to perform an action on them after fetching it from the database. So in Laravel, it provides us Eloquent ORM framework which helps us to perform the database operations easily.

Start Your Free Software Development Course

How does Laravel ORM work?

Laravel provides us which is Eloquent helps us to interact with the database, and allow us to perform the database operations. ORM is generally an object relation mapper which simply means that whatever the objects or model we have in our code maps them to the database entities or table. So for this Laravel provide us with Eloquent which helps us to map our models from code to database tables and allows us to perform the operations as well. Here we will see the implementation of the ORM model using Eloquent in Laravel.

In order to represent the model using table we can follow the below syntax for this:

class Demo extends Eloquent { public static $table = 'demo'; }

Here in this above syntax, we will be going to refer to our ‘demo’ table with the name given below not with one the convection.

By the use of ORM, we can perform different types of operations such as, insert, sort, delete, update and any more.

First, we have to create the model inside our code. Suppose you are maintaining student records inside our database so you might have tables related to that.

So to represent the student models we have to create the ORM for this.

We can create the student ORM using the Eloquent framework or library provided by the Laravel.

Once we are done with the ORM creation for students we can use them against the table in the database.

This ORM will contain the columns which is going to represent the columns inside the table.

We can have the explicit name of the table defined rather than using the convection one.

Once we are done with the creation of the student ORM we can now interact with the database using Eloquent.

So for us, it will convert the student model with the table one, and map all the columns for us.

In this way to helps to interact with the database, in other languages, we have different kinds of ORM available which perform the same thing.

Create Laravel ORM

Here we will see the creation for ORM in Laravel using the Eloquent library because in every framework or language we always have one framework which will handle this ORM part for us, we cannot do this without the formwork.

The creation part of ORM in language.

1. create

Follow this below syntax to create the ORM in language using Eloquent.

class NAME extends Eloquent { public static $table = 'TABLE_NAME'; }

As you can see in the above syntax we are trying to create the ORM using Eloquent, for this, we have to extend the ‘Eloquent’ after this standard syntax we need to follow in order to create it properly.

First, we can specify the class name.

After the class name, we can extend the ‘Eloquent’.

To specify the name of our table we can use ‘$table’ followed by the name of the table.

class Student extends Eloquent { public static $table = 'student'; }

This is the basic step to create the initial structure of the ORM. Now in order to automatically manage the timestamp part Laravel provides us a timestamp which will automatically update the timestamp inside the column.

class Student extends Eloquent { public static $timestamps = true; }

This will automatically update the create_at/ update_at columns in the table. Now we can see few methods which can help us to retrieve the record from the database.

1. To find students with id: For this, we can use find() method, below is the syntax to use this.

$student = Student::find($student_id);

This will give us the result in the ORM that we have created above. Just mentioned the name of your class with the id parameter here to find the record inside the database table.

2. Retrieve all the records from the database: We can retrieve all the records from the database using the below command.

$student = Student::all();

3. Also we can make use of a query aggregator which helps us to retrieve the custom query logic see below to count.

Fish Model

fish/eloquent-logger: This package from fish allows us to logs all the operation into the destined table which include (add, delete, update). To add this inside the application below dependency is required inside the chúng tôi file.

“fish/eloquent-logger”: “^1.0”

fish/one-validator: This package help invalidation, it will convert the server-side validation to a specific jQuery validate plugin, to install this add the below dependency inside the chúng tôi file.

“fish/one-validator”: “dev-master”

Using the Following Artisan Command

It is a CLI, which stands for a command-line interface which is included with Laravel. It provides us list of commands to build our application few of them are mentioned below.

1. For the help window execute the below command.

php artisan help migrate

2. List of artisan command: To view all the commands provided by artisan execute the below command.

php artisan list Conclusion

By this, we understood how to interact with database tables and convert them to code models or simple in POJO classes. This helps us to map our object to a table database table. To simplify this language provide us with Eloquent library which will be easy to use and implement by the developers, readable and understandable as well.

Complete Guide To What Is Laravel Orderby

Introduction to Laravel Orderby

Laravel is one of the most popular frameworks and the reason is not unknown. It is easy to code and robust enough to scale. It provides the developer with enough options to make his/her tasks easier. Laravel also is compatible with other frameworks and hence is a delight to work with. Numerous affiliate frameworks integrate well with Laravel, case in point is the Sprite Billing system. Joins perfectly with Laravel Cashier to create a comprehensive Subscription management system.

Start Your Free Software Development Course

There are plenty of examples that reflect on the flexibility and ease of usage of the framework. That is the reason why Laravel is also one of the most sought after eCommerce frameworks. Customers can simply scale up using the numerous methods and queries available in the library.

One of them is the numerously used Orderby.

What is Laravel Orderby?

Suppose you have a list of products with a host of sub-categories that you would want to view. It will become cumbersome if they all appeared haphazardly. You want order in a world of chaos. The query builder presents you with the command Orderby. Now things are in Order. You can view them by their names, their expiry dates (if it’s a perishable item). It can be anything. The important point is that the Orderby query lists the items in a defined order.

A quick example would be:

In a one to many relationships between the Categories and the Products, we intend to view the products but in an orderly manner. Preferably by their name. The Eloquent relationship will look like this:

Code:

class Category extends Model { public function products() { } } However, the correct way of presenting it would be: public function products() { }

The Laravel Orderby promotes order about the parameters provided. In this case, “name”. Hence, the list that might appear thereafter will be in the form of the name of the products and no other details.

How does Laravel Orderby work?

The Laravel Orderby works by simply sorting the results of the query. So if the column has a list of 20 data, it can sort the list by the parameter provided. One can also create an order in an ascending or a Descending Order.

By Ascending Order:

Example #1

Step #1: This step is to provide some necessary queries

data: function() { return { newMList: { name: ''}, mLists: [], orderToggle: 1, orderAttr: 'name', pagination: { total: 0, per_page: 10, current_page: 1, last_page: 0, from: 1, to: 10 } } }

Step #2: Additional Parameters are inserted as well as the Order by query

Step #4: Two new methods are now inserted. They are: change sort() and getSortIcon()

changeSort: function(attr) { varorderToggle = ( this.orderAttr == attr ) ? this.orderToggle * -1 : 1; this.fetchMLists(attr, orderToggle); } fetchMLists: function (orderAttr, orderToggle) { varorderBy = orderAttr ?orderAttr : this.orderAttr; var order = orderToggle ?orderToggle : this.orderToggle; var progress = this.$Progress; varmLists = []; let params = { perPage: this.pagination.per_page, page: this.pagination.current_page, orderBy: orderBy, order: ( order == 1 ) ? 'asc' : 'desc' }; if ( response.data&&response.data.data&&response.data.data.length ) { this.$set('mLists', response.data.data); this.orderAttr = orderBy; this.orderToggle = order; var pagination = { total: response.data.total, per_page: response.data.per_page, current_page: response.data.current_page, last_page: response.data.last_page, from: response.data.from, to: response.data.to }; this.$set('pagination', pagination); } }, function(error) { swal('An Error Occurred', 'Please refresh the page and try again.', 'error'); }); }

Output:

Explanation: The Order By query sorts the Name parameter as per the instructions provided. The other option is by using the Sort Query. This does the same thing however there is a major difference between these two.

Orderby influences the entire query set. That would primarily mean that the entire query set passes through the single reducer. Now, this is fine if the data set is short and sweet. But for larger data sets, this may take a longer time.

Sort By does that through a local reducer. Hence a local ordering is done. Here each reducer’s output would be sorted. Total ordering will not be done across the entire dataset. However, it is going to be faster. That is a tradeoff many developers might want to make.

Example #2

Code:

SELECT rep_name, rep_country, sales_volume, rank() over (PARTITION BY rep_country ORDER BY sales_volume DESC) as rank FROM salesrep;

However, what makes orderBy() more efficient than sortBy() is because the former is essentially is trying to run a SQL query. Another example would be:

Code:

<?php

// If you want to then sort this collection object to be ordered by the created_at timestamp, you *could* do this. This will run quickly with a small number of rows in the result but will be essentially unusable/so slow that your server will throw 500 errors if the collection contains hundreds or thousands of objects.

That said, Order by is a powerful query that influences a large query set. The cleaner the code or seamless the crossover, the quicker will be the query action. Again this has been the hallmark of Laravel as a whole. It aims to provide clear instructions through its library.

Conclusion

As with all of the Laravel queries, orderBy() helps in a seamless transition. It is an important query and helps in creating order out of insanity.
