Step-by-Step Guide: How to Create a Hologram Viewer using Pepper's Ghost

2023-02-28T11:17:00.028+05:30

Holograms have long been a staple of science fiction, but in recent years, they’ve become more of a reality than ever before. Thanks to advances in technology, it’s now possible to create holograms using everyday materials like plexiglass. In this blog post, I’ll walk you through the steps to create your own hologram viewer using plexiglass.

Materials Needed:

Plexiglass sheet or Transparent CD Case
Ruler
Pen
Scissors or utility knife
Tape
Smartphone or tablet
Hologram video

Step 1: Measure and Cut Your Plexiglass Sheet

The first step in creating your hologram viewer is to measure and cut your plexiglass sheet.

(Plexi Glass, you can use CD case also)

Using a ruler and a pen, measure out a square that is 15cm x 15cm. Once you have your square marked out, use scissors or a utility knife to carefully cut along the lines.

Step 2: Create Your Pyramid Shape

After you have your plexiglass square, the next step is to create your pyramid shape. To do this, take your cut plexiglass square and fold it into a triangle, making sure the edges are aligned perfectly. You should now have a pyramid-shaped piece of plexiglass.

Step 3: Prepare Your Smartphone or Tablet

To create a hologram, you’ll need a video that’s specifically designed for hologram viewing. There are many hologram videos available on YouTube that you can use for this purpose. Once you have your video, play it on your smartphone or tablet and turn the brightness up to maximum.

Step 4: Place Your Pyramid Over the Video

With your hologram video playing on your smartphone or tablet, place your plexiglass pyramid over the device. Make sure the pyramid is centered over the screen and that the edges of the pyramid are aligned with the edges of the device.

Step 5: Enjoy Your Hologram

With your pyramid in place, you should now be able to see the hologram floating above your device. Move around the viewer to see the hologram from different angles and enjoy the 3D effect.

Here is the working video,

How it works ?

The hologram works based on the principle Pepper’s Ghost.

Pepper’s ghost is a type of holographic illusion that has been used in theaters and other entertainment venues for over a century. The illusion is created by reflecting an image onto a transparent surface, such as a piece of glass or plastic, and then illuminating it from below or behind.

Here’s a simplified explanation of how the Pepper’s ghost illusion works:

An image or object is placed in a hidden area, such as below the stage, and is lit with bright lights.
A large sheet of clear plastic or glass is set up at a 45-degree angle between the hidden area and the audience.
The audience sees the reflection of the image or object in the sheet of plastic or glass, creating the illusion that the image or object is on stage or floating in mid-air.
By carefully controlling the lighting and angles of the reflection, it’s possible to create the illusion of movement and even interaction between the holographic object and real-world objects on stage.

Pepper’s ghost is often used in modern hologram displays, such as those used in concerts, museums, and other events. These displays use a combination of computer-generated imagery and projection techniques to create more complex and realistic holographic images.

Conclusion:

Creating a hologram viewer using plexiglass is a fun and easy project that anyone can do. With just a few simple materials and some basic tools, you can create a stunning hologram that will amaze and entertain your friends and family. So why not give it a try and see what kind of holograms you can create?

Internet Radio with Malayalam Channels

2022-11-21T20:04:00.008+05:30

In today's digital age, creating an internet radio has become easier than ever before. With just a few simple steps, you can set up your own radio station and broadcast your favorite tunes to the world. In this article, we'll show you how to create an internet radio using HTML, with the help of external radio stations.

Getting Started

To get started with your internet radio, you will need basic knowledge of HTML, CSS, and JavaScript. You will also need a web server to host your radio station. You can either use a free web hosting service or a paid one, depending on your budget.

Next, you need to find external radio stations that you want to broadcast on your radio. There are several online directories where you can find radio stations based on genre or location. You can also search for the radio station's URL directly.

Adding Your Own Audio Content

In addition to broadcasting external radio stations, you can also add your own audio content to your internet radio. To do this, you will need to convert your audio files to a compatible format, such as MP3 or AAC. You can then host these files on your web server and add them to your HTML page using the same <audio> tag as before.

Promoting Your Internet Radio

Once your internet radio is up and running, it's time to promote it to the world. You can start by sharing your radio station on social media platforms like Facebook, Twitter, and Instagram. You can also submit your radio station to online radio directories to reach a wider audience.

Reviving the Past: Deep Learning Transforms Old Videos into Vibrant Colors

2022-03-01T07:01:00.010+05:30

Have you ever come across old black and white videos and wondered what they would look like if they were in color? With the advancement of deep learning, it is now possible to transform black and white videos into colored ones with stunning accuracy.

My new project is about colorizing black and white evergreen songs. The colors may not be perfect since this is not a studio level film roll remastering, but we can get the look and feel of how the video will be if shot with a color camera.

The process of colorizing old videos involves training deep neural networks to predict the colors of each pixel in a grayscale image. The neural network is trained on a large dataset of images to learn the relationship between the grayscale and color images. Once trained, the neural network can be used to colorize new grayscale images or videos.

One of the most popular methods for colorizing videos is to use a technique called "frame interpolation." This technique involves using a neural network to predict the colors of intermediate frames between two existing frames. This results in smoother transitions between frames and a more natural-looking colorization.

Another approach is to use a technique called "temporal coherence." This technique involves ensuring that the colorization of one frame is consistent with the colorization of the surrounding frames. This helps to prevent color flickering and produces a more visually pleasing result.

One of the benefits of using deep learning to colorize old videos is that it can be done automatically and in real-time. This makes it possible to colorize old movies and TV shows, bringing them to life in a way that was never before possible. It also allows us to see historical events and footage in a new light, with colors that were previously hidden.

However, there are also some limitations to this technology. One of the challenges is that the neural network may make errors in predicting the colors of certain objects or regions in the video. For example, if there are no reference images of a particular car model, the neural network may not be able to accurately predict its color. Another challenge is that the colorization process may introduce artifacts or noise into the video.

Despite these challenges, the technology for colorizing old videos using deep learning is rapidly advancing. It is now possible to produce colorized videos that are visually stunning and incredibly realistic. With further improvements to the technology, we may soon be able to see the world in a whole new way, with old videos and images transformed into vibrant and colorful representations of the past.

This is my first try,

Breaking Language Barriers: How Deep Learning Automates Language Conversion of Comics

2022-02-20T07:31:00.005+05:30

My next project is about converting comics to my native language. Since manual work is a time consuming, we are discussing about automating this. So took my first comic, Doctor Strange(English), and lets talk about the steps involved in this.

Comics are a form of visual storytelling that have gained immense popularity over the years. However, one of the challenges in reading comics is that they are often published in a single language, making them inaccessible to people who don't understand that language. But with the help of deep learning, it is now possible to automate the language conversion of comics, making them accessible to a wider audience.

The process of automating language conversion of comics involves training deep neural networks to recognize and translate text from one language to another. The neural network is trained on a large dataset of comics and their translations to learn the relationship between the text and the images. Once trained, the neural network can be used to automatically translate the text in new comics.

One of the challenges in automating language conversion of comics is that the text is often integrated with the images. This means that the neural network needs to be able to recognize and extract the text from the images. One approach to addressing this challenge is to use Optical Character Recognition (OCR) technology, which can recognize and extract text from images.

Another challenge is that different languages may have different sentence structures and word orders, making it difficult for the neural network to accurately translate the text. To address this, the neural network can be trained on a larger dataset of translations to improve its accuracy.

One of the benefits of automating language conversion of comics is that it can be done automatically and in real-time. This makes it possible for publishers to translate their comics into multiple languages without the need for manual translation. It also makes comics more accessible to people who may not have access to translations, such as those living in remote areas or those with visual impairments.

However, there are also some limitations to this technology. One of the challenges is that the neural network may make errors in translating certain words or phrases, especially those with multiple meanings. Another challenge is that the translated text may not always fit seamlessly with the images, which can be distracting for readers.

Despite these challenges, the technology for automating language conversion of comics using deep learning is rapidly advancing. It is now possible to produce translated comics that are visually stunning and accurate in their translations. With further improvements to the technology, we may soon be able to enjoy comics in multiple languages, bringing new audiences to this beloved form of storytelling.

In conclusion, automating language conversion of comics using deep learning is a promising technology that has the potential to revolutionize the comic industry. By making comics more accessible to a wider audience, we can foster a greater appreciation for this unique form of storytelling and bring people together across language barriers.

This is the page we are going to translate,

Step 1: Detection of text, conversation: This involves passing the image through a deep learning model to identify all the balloons in it.

Step 2: OCRing, So we have the location of all text boxes with us. So we will take each of them and pass through it via an OCR. The quality of OCR depends on the quality of the source image, we can use Tesseract, Abby, Google or any OCR as needed.

So we will get something like this,

Step 3: Translation is the next step. We can use any kind of language translators available for translation.

At this point, the translation may not be perfect. So we cannot fully depend on a translator and s we need to tune it or we should create our own translation model for each type of comic and then do the translation. Different comics use different own kind of dialogues/phrases and content delivery, like for Amar Chitra Katha the English’s content will be different and for Marvel comics it will be exactly different. So we cannot convert them based on any available conversational models for a professional output, but automated translation works for the time being.

Step 4: Text Masking: So now we know where are out texts, so the next step is to mask all the texts in it. This uses AI models to detect text in the balloons that we detected, and remove them. OR just clear all the balloons which may not be perfect since balloons can be of any shape.

Step 5: Replace original text, we can now paste our translated contents over this bubbles.

So yes we have the comic ready.

Here I’m adding the converted comic (Just a couple of pages only.)

Original: Dr. Strange from Marvel

Translated: Dr. Strange From Marvel – Malayalam Translated

Here is one more,

This I did in a hurry (ignore the imperfect mask removal), but it does the job.

Original: Arjun Unicrystal
Translated: Arjun – Unicrystal – Malayalam Translated

So if you want to convert any comics can P.M me, all we need is a person (manual translator) who can verify the automatic translated content and do the correction.

Thanks for reading.

Maximize Your Trading Potential with Our Stock Trading Tracker and Alert Tool on Telegram

2021-07-01T19:19:00.021+05:30

Are you a stock trader looking to learn and earn? Look no further than NSE Trading Alerts, the ultimate resource for trading setups and ideas.

Our comprehensive spreadsheet provides you with all the technical aspects you need to know, including which scrip to buy and at what price. We even update it frequently during market hours to identify good setups and publish them in real-time.

But we know you're busy, and checking the spreadsheet periodically might not be feasible. That's why we've created a telegram channel where you can get trading setups and ideas directly in the channel – no need to leave the app.

Plus, we've added new functionality with alerts that notify you when a scrip's CMP is near the trigger price, making it easier to identify the right trade. And the best part? The channel is completely free to use.

My new project is for Stock Traders who want to study and earn.

So I’ve created a spreadsheet with trading setup’s where you can see which scrip to buy at what price. This will be a bit educational also as it will explain the technical aspects also.

And here is the link if you want to take a look:

https://docs.google.com/spreadsheets/d/1Pi3bViTDWwgxEjK44hiWJCrhOFT2yR_T-RQ08bm16UM/edit#gid=0

The sheet will update frequently during market hours to identify good setups and publish it in the spreadsheet with its trigger price. I’m not publishing SL or Target you can set your own Target and SL based on your convenience. There is also a MaxMove column to watch out for to see how much the scrip went after triggering.

The next thing that came to my mind is that somebody might need to look at the sheet periodically to enter a good setup and this might not be useable for someone who is busy or not an intraday trader.

the answer is telegram channel…

So I’ve created a new channel in telegram @nsetradingalerts

Once you joined the channel, you will get trading setups and ideas in the channel itself, no need to go and check the spreadsheet.

Here are a couple of screenshots of how the channel looks like:

Now comes the main issue, there will be a lot of ideas and possible setups in the channel and it will be difficult to identify a good one during a trade.

So I’ve added new functionality – Alerts

Now the channel will notify you if its CMP is near the trigger price (not at the trigger price as you may miss the entry) and it will send an alert to the channel which will be much easier to identify the right trade.

Here is a screenshot:

The channel is free to use, those who are interested can join at https://t.me/s/nsetradingalerts

Disclaimer: This is for educational purposes only, I’m not a SEBI registered analyst. Take advice from your financial experts before jumping into any trade.

Travancore Photos Old vs Restored

2021-05-09T13:03:00.000+05:30

I’m trying to restore the old Travancore photos in color format using deep learning AI methods.

Most of these original photos are taken from “Album of South Indian Views” from the Curzon Collection taken by Govt. Photographer Zacharias D’Cruz during 1900’s others are from various websites I found.

So here are those…

Photograph of the gopura of the Padmanabha Temple at Trivandrum during 1890s. This ancient Hindu temple is one of the greatest of Kerala and was patronized mainly in the 18th century by the Travancore kings. The sanctuary, which enshrines a large image of Vishnu, is built in the typical Kerala style while the surrounding walls and towers are similar to those of the Dravidian architecture of Tamil Nadu. The imposing gopura or entrance gateway consists of ascending storeys ending with a vaulted roof and reflect the contemporary Nayaka style of architecture.

Maharaja’s State Carriage in Trivandrum. It was drawn by a team of six horses. In the background can be seen the gopuram of the Padmanabha Swamy temple.

A rare image from 1900’s of the richest temple in India, Padmanabhaswamy Temple.

This will be a live page, more photos will be added in the coming days.

Reviving History: Sree Padmanabha Swamy Temple During 1895 Comes to Life in HD Color with Deep Learning Technology

2021-04-25T12:03:00.009+05:30

One of the most amazing things about artificial intelligence is its ability to learn and improve through experience. This is especially true for deep learning, a subset of AI that uses neural networks to analyze and learn from data. Colorization and enhancement of images and videos is one area where deep learning has made significant strides, and it's all thanks to the power of AI.

Colorization involves adding color to grayscale images or videos, while enhancement refers to improving the overall quality of an image or video, such as sharpening or denoising. These tasks were traditionally done manually, requiring a lot of time and effort from professionals. But with the advent of deep learning, these tasks can now be done quickly and accurately.

One of the most popular methods for colorization and enhancement is using deep neural networks, which are trained on large datasets of images and videos. The neural networks learn to recognize patterns and relationships between the grayscale and color or degraded and enhanced versions of the same image. Once the neural network has been trained, it can be used to apply color or enhancement to new images or videos.

Another technique used for colorization is to use reference images, where a neural network is trained to learn the color distribution of similar images. This allows the neural network to predict the colors of the pixels in a grayscale image more accurately.

Deep learning has also made it possible to enhance images and videos in real-time, which is useful for applications such as video conferencing or live streaming. This involves using deep neural networks to remove noise, blur, or other imperfections from an image or video in real-time, producing a clearer and more visually pleasing result.

One of the benefits of using deep learning for colorization and enhancement is that it can be done automatically and at scale. This means that large amounts of images and videos can be colorized or enhanced quickly and with a high degree of accuracy. This also saves professionals a significant amount of time and effort, allowing them to focus on other tasks.

However, there are also some limitations to this technology. For example, if the neural network has not been trained on a specific object or scene, it may not be able to accurately colorize or enhance it. Additionally, the colorization or enhancement process may introduce artifacts or errors into the image or video.

Despite these challenges, deep learning AI has revolutionized the way we approach colorization and enhancement of images and videos. It has made it easier and more accessible for professionals to produce high-quality images and videos, while also offering new possibilities for real-time applications. As deep learning technology continues to improve, we can expect to see even more exciting developments in this area.

Colorization and enhancing is done by deep learning AI.

Reliving History: Nehru's 1958 Visit to Thiruvananthapuram in Stunning 4K Color Restoration with Deep Learning AI

2021-04-24T11:41:00.004+05:30

This is my first attempt of video restoration with deep learning AI models.

Color restoration using deep learning AI is an exciting and innovative technology that can bring old black and white photographs and videos to life. By using artificial intelligence algorithms, it is possible to add color to historic images and videos with incredible accuracy and detail, providing a new and captivating way to relive the past.

One fascinating example of the power of deep learning AI color restoration is the restoration of old footage of Jawaharlal Nehru's visit to Thiruvananthapuram in 1958. The original footage was in black and white, but with the help of deep learning AI, it has been colorized to stunning effect, providing a vivid and immersive experience of this historic event.

The process of color restoration using deep learning AI involves training a neural network on a vast dataset of images and videos to recognize and replicate the colors that would have been present in the original scene. This involves teaching the network to recognize patterns and textures, as well as to understand the relationships between different colors in the image.

Once the neural network has been trained, it can be used to colorize new images and videos with remarkable accuracy. The technology can be used to add color to everything from historic photographs and film footage to more recent digital media, providing a new and engaging way to experience the past.

Color restoration using deep learning AI is not without its challenges, however. The technology requires access to high-quality source material, as well as careful calibration to ensure that the colors are accurately replicated. It also requires significant computational resources to process large datasets and produce high-quality results.

Despite these challenges, the potential benefits of color restoration using deep learning AI are enormous. By bringing historic images and videos to life in full color, this technology offers a new and immersive way to experience the past, enabling us to connect with history in a more immediate and engaging way than ever before.

For the first time since the Communist assumption of power in the state of Kerala, India, the Prime Minister of India, Mr. Jawaharlal Nehru has paid an official state visit.

His first point of call was at Trivandrum, the capital where he was met by the Governor of the State, Mr Ramakrishna Rao (wearing the cap) and the Communist Chief Minister Mr. E.M.S. Nambudripad. The Governor garlanded Mr. Nehru as he stepped down from the plane, and shook hands. Then flowers and Arti (candle lights) were offered in Kerala traditional, fashion, and 68 pigeons were released to follow the one Mr. Nehru released, the whole to symbolize Mr. Nehru’s 69 years of peaceful life.

On the way into the town shouting crowds lined the route ‘Nehru Zindabad’ they called – Long Live Nehru – Later Mr. Nehru inaugurated the Mahatma Gandhi College in Trivandrum.

Comet Lovejoy aka C/2014 Q2 captured from Thiruvananthapuram Kerala INDIA

2020-01-07T21:10:00.006+05:30

This is my second experience in capturing a comet. This time its Lovejoy. The photo was taken from Thiruvananthapuram (Google Map). The sky was too polluted due to the nearby airport lights, so direct single capture was impossible. And I’ve managed it by taking multiple shots of dark, light, flats and biased pics using a prime lens(50mm) with f/2.8 and processed using Registax.

Here is the output,

Date: INDIA on 24th Jan 2015 7:30 PM. The image is taken without telescope, using DSLR with 50mm lens.

C/2014 Q2 (Lovejoy) is a long-period comet discovered on 17 August 2014 by Terry Lovejoy using a 0.2-meter (8 in) Schmidt–Cassegrain telescope. It was discovered at apparent magnitude 15 in the southern constellation of Puppis. It is the fifth comet discovered by Terry Lovejoy.

By December 2014, the comet had brightened to roughly magnitude 7.4, making it a small telescope and binoculars target. By mid-December, the comet was visible to the naked eye for experienced observers with dark skies and keen eyesight. On 28−29 December 2014, the comet passed 1/3° from globular cluster Messier 79. In January 2015, it brightened to roughly magnitude 4−5, and became one of the brightest comets located high in a dark sky in years. On 7 January 2015, the comet passed 0.469 AU (70,200,000 km; 43,600,000 mi) from Earth. It crossed the celestial equator on 9 January 2015 becoming better seen from the northern hemisphere. The comet will come to perihelion (closest approach to the Sun) on 30 January 2015 at a distance of 1.29 AU (193,000,000 km; 120,000,000 mi) from the Sun.

Before entering the planetary region (epoch 1950), C/2014 Q2 had an orbital period of about 11000 years. After leaving the planetary region (epoch 2050), it will have an orbital period of about 8000 years.

Annular Solar Eclipse From Thiruvananthapuram

2019-12-31T20:52:00.011+05:30

26th Dec was a luck day For Keralites to capture the Annular Solar Eclipse.

So what is an annular solar eclipse?

An annular solar eclipse happens when the Moon covers the Sun’s center, leaving the Sun’s visible outer edges to form a “ring of fire” or annulus around the Moon. The characteristic “ring of fire”. The ring of fire marks the maximum stage of an annular solar eclipse. (Ref)

So I too got a chance to capture the rare moment, even though our location is only having partial eclipse.

and here is my pic…

Date: 26th Dec 2019

Time: 8:00 AM to 11:15 AM
Location: Thiruvananthapuram, Kerala, India (8.5241° N, 76.9366° E)
Gear: Nikon D610 + 300MM + 1.4 TC with DIY Filter, Smart Camera Assistant, Tripod

And the next Annular Eclipse through Kerala will be on 2031.

Rare planet alignment Mars-Venus-Saturn-Jupiter from Thiruvananthapuram Kerala INDIA

2019-12-31T20:35:00.008+05:30

For the first time in more than a decade, ‪#‎Mercury‬, ‪#‎Mars‬, ‪#‎Venus‬, ‪#‎Saturn‬ and ‪#‎Jupiter‬ — the five ‪#‎planets‬ bright enough to be seen with an unaided eye — was visible at once in the sky.

Missing mercury in the image because the sky was super cloudy and mercury was too faint. The image looks too wide as Venus and Jupiter were at both ends of the field.

Mercury will appear lowest to the horizon, and its faint light will be hardest to spot in the southeastern sky (in the Northern Hemisphere). Then, from left to right (from southeast to southwest), you’ll be able to see Venus, Saturn, Mars, and Jupiter, in a line that roughly traces the path the sun will take through the day.

The image is taken from the top of Thejaswini Building, Technopark, Thiruvananthapuram, Kerala, INDIA at 5:40AM on 20th Jan 2016.

mongoose-paginate-v2

2019-12-30T21:36:00.001+05:30

I’ve developed this plugin to easily bring customized paginated results for NodeJS projects using MongoDB.

NPM Package: https://www.npmjs.com/package/mongoose-paginate-v2

Installation
npm install mongoose-paginate-v2

Usage
Add plugin to a schema and then use model paginate method:

const mongoose = require('mongoose');const mongoosePaginate = require('mongoose-paginate-v2');const mySchema = new mongoose.Schema({/* your schema definition */});mySchema.plugin(mongoosePaginate);const myModel = mongoose.model('SampleModel', mySchema);myModel.paginate().then({}) // UsageModel.paginate([query], [options], [callback])Returns promise

A cursor based custom pagination library for Mongoose with customizable labels.

2018-07-23T22:57:00.001+05:30

Installation

npm install mongoose-paginate-v2

Usage

Add plugin to a schema and then use model paginate method:

var mongoose         = require('mongoose');
var mongoosePaginate = require('mongoose-paginate-v2');

var mySchema = new mongoose.Schema({ 
    /* your schema definition */ 
});

mySchema.plugin(mongoosePaginate);

var myModel = mongoose.model('SampleModel',  mySchema); 

myModel.paginate().then({}) // Usage

Model.paginate([query], [options], [callback])

Returns promise

Parameters

[query] {Object} - Query criteria. Documentation
[options] {Object}
- [select] {Object | String} - Fields to return (by default returns all fields). Documentation
- [sort] {Object | String} - Sort order. Documentation
- [populate] {Array | Object | String} - Paths which should be populated with other documents. Documentation
- [lean=false] {Boolean} - Should return plain javascript objects instead of Mongoose documents? Documentation
- [leanWithId=true] {Boolean} - If lean and leanWithId are true, adds id field with string representation of _idto every document
- [offset=0] {Number} - Use offset or page to set skip position
- [page=1] {Number}
- [limit=10] {Number}
- [customLabels] {Object} - Developers can provide custom labels for manipulating the response data.
[callback(err, result)] - If specified the callback is called once pagination results are retrieved or when an error has occurred

Return value

Promise fulfilled with object having properties:

docs {Array} - Array of documents
totalDocs {Number} - Total number of documents in collection that match a query
limit {Number} - Limit that was used
hasPrevPage {Bool} - Availability of prev page.
hasNextPage {Bool} - Availability of next page.
page {Number} - Current page number
totalPages {Number} - Total number of pages.
offset {Number} - Only if specified or default page/offset values were used
prevPage {Number} - Previous page number if available or NULL
nextPage {Number} - Next page number if available or NULL

Please note that the above properties can be renamed by setting customLabel attribute.

Sample Usage

Return first 10 documents from 100

const options = {
    page: 1,
    limit: 10
};

Model.paginate({}, options, function(err, result) {
    // result.docs
    // result.totalDocs = 100
    // result.limit = 10
    // result.page = 1
    // result.totalPages = 10    
    // result.hasNextPage = true
    // result.nextPage = 2
    // result.hasPrevPage = false
    // result.prevPage = null
    
});

With custom return labels

Now developers can specify the return field names if they want. Below are the list of attributes whose name can be changed.

totalDocs
docs
limit
page
nextPage
prevPage
totalPages

You should pass the names of the properties you wish to changes using customLabels object in options.

Same query with custom labels

const myCustomLabels = {
    totalDocs: 'itemCount',
    docs: 'itemsList',
    limit: 'perPage',
    page: 'currentPage',
    nextPage: 'next',
    prevPage: 'prev',
    totalPages: 'pageCount'
};

const options = {
    page: 1,
    limit: 10,
    customLabels: myCustomLabels
};

Model.paginate({}, options, function(err, result) {
    // result.itemsList [here docs become itemsList]
    // result.itemCount = 100 [here totalDocs becomes itemCount]
    // result.perPage = 10 [here limit becomes perPage]
    // result.currentPage = 1 [here page becomes currentPage]
    // result.pageCount = 10 [here totalPages becomes pageCount]
    // result.next = 2 [here nextPage becomes next]
    // result.prev = null [here prevPage becomes prev]
    
    // result.hasNextPage = true [not changeable]
    // result.hasPrevPage = false [not changeable]
});

Other Examples

Using offset and limit:

Model.paginate({}, { offset: 30, limit: 10 }, function(err, result) {
    // result.docs
    // result.totalPages
    // result.limit - 10
    // result.offset - 30
});

With promise:

Model.paginate({}, { offset: 30, limit: 10 }).then(function(result) {
    // ...
});

More advanced example

var query   = {};
var options = {
    select:   'title date author',
    sort:     { date: -1 },
    populate: 'author',
    lean:     true,
    offset:   20, 
    limit:    10
};

Book.paginate(query, options).then(function(result) {
    // ...
});

Zero limit

You can use limit=0 to get only metadata:

Model.paginate({}, { offset: 100, limit: 0 }).then(function(result) {
    // result.docs - empty array
    // result.totalDocs
    // result.limit - 0
    // result.offset - 100
});

Set custom default options for all queries

config.js:

var mongoosePaginate = require('mongoose-paginate-v2');

mongoosePaginate.paginate.options = { 
    lean:  true,
    limit: 20
};

controller.js:

Model.paginate().then(function(result) {
    // result.docs - array of plain javascript objects
    // result.limit - 20
});

How to add title and image header to all pages while printing using DataTable

2018-07-17T00:25:00.002+05:30

Step 1

Download below JS file and replace your print.button.js with below it,https://github.com/aravindnc/Buttons/blob/repeating-print-head/js/buttons.print.js

Step 2

Add new option repeatingHead inside the button settings.

Below are the options for repeatingHead,

{
    logo: 'Your logo URL to be repeated',
    logoPosition: 'right', // left, center, right
    logoStyle: '', // any css eg: padding:10px;
    title: '
Sample Heading
' // your heading
}

A sample is given below.

<script>
    $(document).ready(function() {
        // DataTable initialisation
        $('#example').DataTable({
            "dom": 'Bfrtip',
            "paging": true,
            "autoWidth": true,
            "columnDefs": [{
                "visible": true,
                "targets": -1
            }],
            buttons: [{
                extend: 'print',
                autoPrint: true,
                title: '',

                //For repeating heading.
                repeatingHead: {
                    logo: 'https://www.google.co.in/logos/doodles/2018/world-cup-2018-day-22-5384495837478912-s.png',
                    logoPosition: 'right',
                    logoStyle: '',
                    title: '
Sample Heading
'
                }
            }]
        });
    });
</script>

Step 3

If you want to remove the borders around logo, add a new class dt-print-table to your table and add below style to your css file.

@media print
{
html, body { height: auto; }
.dt-print-table, .dt-print-table thead, .dt-print-table th, .dt-print-table tr {border: 0 none !important;}
}

Thats all :)

Create signed AWS request using PHP

2018-01-16T00:37:00.002+05:30

Here is a simple way to generate a signed request for diferent services using AWS:

/// AWS API keys
$aws_access_key_id = 'your-aws-access-key';
$aws_secret_access_key = 'your-aws-secret';

// AWS region and Host Name (Host names are different for each AWS region)
// As an example these are set to us-west-2
$aws_region = 'us-west-2';
$host_name = 'your-url.amazonaws.com';

// MIME type of file.
$content_type = 'application/x-www-form-urlencoded';

// Service name
$aws_service_name = 'execute-api';

// UTC timestamp and date
$timestamp = gmdate('Ymd\THis\Z');
$date = gmdate('Ymd');

// HTTP request headers as key & value
$request_headers = array();
$request_headers['content-type'] = $content_type;
$request_headers['x-amz-date'] = $timestamp;
$request_headers['host'] = $host_name;

// Sort it in ascending order
ksort($request_headers);

// Canonical headers
$canonical_headers = [];
foreach($request_headers as $key => $value) {
$canonical_headers[] = strtolower($key) . ":" . $value;
