Slack as a teamwork tool

Hello People. This article is about how to use Slack as a teamwork tool. As you know, Slack contains channels. You can create a different channel for each of your purpose. Channel contains all the people, messages and files related to a topic in one place.

In short, Slack is basically a messaging app. Teams and workplaces can be use Slack across multiple devices and platforms. You’re able to upload and share files with your groups too. You can also integrate with other apps and services and you can control almost every setting.

Slack Pricing

Slack is mostly free of cost to use. However you’ll only be able to browse and search your team’s 10,000 most recent messages, and you’ll be limited to 5GB of file storage and 10 apps or custom integrations. As of now, there are three pricing tiers available: Free, Standard ($8 or £5.25 a month billed monthly), and Plus ($15 or £9.75 a month billed monthly). A fourth tier, called Enterprise Grid, has special pricing for corporates.

How to start using Slack?

If you are an administrator of a team, please follow these steps:

  1. Go to Slack’s website and enter your email address to sign up 
  2. Choose a name for your Slack team
  3. Edit the URL to your Slack team
  4. Choose a username for yourself
  5. Enter emails of associates you’d like to invite to join your Slack team
  6. Your Slack team chat will then load in a browser window

Slack Settings

Click on your username or the drop-down arrow next to the Slack team name to access a settings menu. From here you can adjust your preferences (themes for the sidebar, messages, emoji style, and more), view your profile and account, access a Help/Feedback page, get Slack apps (more on that later), and set yourself to away.

If you’re an administrator, you can also access team settings, billing, etc. Team members will only see options to access app integrations, customise slack, and jump to team directory.

Blockchain technology using Javascript

Hello People. This article is about Blockchain technology using Javascript. As you already know, a blockchain is an open, digital, and duplicated ledger of transactions. Every new transaction history is recorded and stored in an encrypted way that is very difficult to modify. A copy of this recorded information is sent a cross the blockchain network. This makes it highly secure.

Blockchains are blocks of transaction data growing increasingly to create a chain of transaction occurrences. Valid transaction data is logged into the blockchain network following the peer-to-peer rule laid down by participants. Normally, the data in the databases are centralized. This means we operate based on only one server. Chances of risk are high due to failures of the system. Alternatively, decentralization allows data to be stored everywhere, thus making it faster, more secure and a better way of storing data.

We need to first install the crypto library using the command:

npm install --save crypto-js

We’ll use this library to import modules in our project.

We can start by creating a class BlockCypto as shown below:

const SHA256 = require('crypto-js/sha256');
class BlockCypto{
    constructor(index, current_time, info, nextHash=" "){
    this.index = index;
    this.current_time = current_time;
    this.info = info;
    this.nextHash = nextHash;
    this.hash = this.computeHash();     
    }
    computeHash(){
        return SHA256(this.info + this.nextHash + this.current_time + JSON.stringify(this.info)).toString();
    }   
}

Let us see each part of the code here:

We have created the class BlockCrytpo for our block and added a constructor just like any other JavaScript class.

In the constructor, we initialize its properties and assign parameters to it, as follows:

  • crypto-js/sha256: This is the module we’ve imported to calculate the hash of each block. We converted it to string using toString() method as the module will return the object.
  • index: This is a distinctive number tracking the index of every block in the blockchain.
  • current_time: As the name states, it keeps a record of the time when each transaction is completed.
  • info: All completed transactions data are recorded and stored by this method.
  • nexthash: It is pointing to the hash_key of the next block in the network chain. It’s mainly used to keep and maintain the integrity of the blockchain.
  • computeHash: Based on properties passed to this method, it is used to calculate the hashkey of the next block in the chain.
Blockchain technology using Javascript

What is blockchain theorem?

It is a type of database that stores a collection of data together in groups, with certain capacity of storage. The blocks are connected to the already created blocks, this forms a chain of a data tree.

The chain is irreversible as the system is decentralized. Here, each block is assigned a timestamp when added to the chain.

Now, let’s create a class Blockchain that will maintain this operation:

class Blockchain{
    constructor(){
        this.block1chain = [this.startGenesisBlock()];     
    }
    initGenesisBlock(){
        return new BlockCrypto(0, "06/04/2021", "Initial Block in the Chain", "0");
    }
    latestBlock(){
        return this.block1chain[this.block1chain.length - 1];
    }
    addNewBlock(newBlock){
        newBlock.nextHash = this.latestBlock().hash;
        newBlock.hash = newBlock.computeHash();        
        this.block1chain.push(newBlock);
    }
}

Let’s understand the code snippet above.

As usual, we have our constructor which instantiates the blockchain.

But this time, we passed it to the initGenesisBlock() method, which initializes the block in the chain. This property refers to an array of blocks in our case.

  • initGenesisBlock(): This is the first block created in the peer-to-peer network and has not been linked to any other. To our knowledge of indexing it’s at index 0.
  • latestBlock: As named, we use it for finding the last block added in the chain. As explained earlier, it helps to ensure the hash of the current block and map it to the hash of the previous block to ensure the chain integrity.
  • addNewBlock: A new block is added to the chain using this method. The previous hash block is matched to the current hash block to ensure minimal or no tampering with the chain.

Now that our blockchain is ready to work. We are missing something that is a core blockchain principle, the blockchain integrity.

Let’s see how to verify it and test our app.

Verifying blockchain integrity

The main characteristic of a blockchain is that once a block has been added to the network, it can’t be changed without invalidating the entire blockchain integrity.

To perform this, we use digital security or cryptographic hash, which ensures the securing and validation of the blockchain by producing a new hash every time a change is made in the block.

We’ll loop over the entire blockchain to check whether any hash has been tampered with, taking into account the exception of the first block, which is hardcoded.

Besides, this method verifies if the cryptographic-key of each two blocks in series are pointing to one another. If the integrity of the blockchain has been compromised, it returns false; otherwise, in case no anomalies are encountered, it returns true.

We’ll create this method inside the Blockchain class:

checkValidity(){
    // Checking validity
    for(let i = 1; i < this.block1chain.length; i++) {
        const currentBlock = this.block1chain[i];
        const nextBlock= this.blockchain[i-1];
    // Checking current blcok hash
    
    if(currentBlock.hash !== currentBlock.computeHash()) {
        return false;
    }
    // Comparing current block hash with the next block

    if(currentBlock.nextHash !== nextBlock.hash) {
        return false;
    }
    return true;
}

Now, we can test our app and see the results:

But, before we dive into running the code, let’s create a new instance of the Blockchain class and name it thecoin, and add some blocks in the blockchain using random values.

let thecoin = new Blockchain();

thecoin.addNewBlock(new BlockCrypto(1, "06/04/2021", {sender: "Rabin Yitzack", recipient: "Loyd Eve", quantity: 20}));

thecoin.addNewBlock(new BlockCrypto(2, "07/04/2021", {sender: "Anita Vyona", recipient: "Felix Mush", quantity: 349}));

console.log(JSON.stringify(thecoin, null, 4));

Took Too Long to Respond error

Hello People. This article discusses about the “took too long to respond error”. Sometimes you might encounter the ‘website took too long to respond’ error when you try to access a particular website. This error indicates that there is a communication problem between the target server and the client. In this case your web browser. It must be understood that the targeted server is taking a long time to send a response to the client. The error appears if the client cannot get a response within 30 seconds. The connection attempt is then terminated.

Reasons for the ‘took too long to respond’ error?

Here are the reasons.

Internet connection problem

If you do not have an internet connection, this error occurs. Check that your device is connected to internet via a LAN or Wi-Fi. If you use a LAN, you need to check your LAN settings. You also need to make sure that your TCP/ipv4 protocols are correctly configured.

Much load on the server

If you are using shared hosting, there is a possibility that there is not enough memory to allow for a connection between your client and server. When using shared hosting, memory allocation is not equally distributed. There might be sites that use a lot of memory, leaving others with little memory available. Contact your service provider about your memory limit. If you are using WordPress, you can check your memory limit in the ‘Site Health Tool’ on your dashboard.

You may also want to change your hosting plan to a VPS (Virtual Private Server) package, where memory is shared equally among users.

There are also other reasons that may cause your site to be overwhelmed. Increase in site traffic, or code and scripts that have not been deferred to load only after your site fully loads.


Took Too Long to Respond error

Antivirus is blocking site access

Sometimes Your antivirus might block access to some sites or even all of them. You may need to temporarily disable it and see whether the ‘taking too long’ error is resolved.

DNS cache

The DNS (Domain Name System) is what converts domain names to IP addresses. DNS results are usually cached in order to make sure that subsequent requests are handled faster. If there was a communication problem between client and server, it may be cached, resulting in the ‘website took too long to respond’ error. Clearing the DNS cache should solve the error.

Outdated extensions

Extensions may not be as frequently updated for compatibility with web browsers. On Chrome, virus scanning extensions, for example, Symantec, outdated or not, tend to be ‘heavy’, which slows down your browser.

Browsing history

Stored data from browsing sessions such as saved passwords, cookies, site names, and URLs, as well as cache can contribute to client-server communication problems.

Chrome’s default profile folder issues

There is always a folder named ‘Default’ on your local machine which store’s your ‘Chrome Profile’ (your bookmarks, saved passwords, apps, browser settings, and extensions). If there is corrupted content in the folder, it may affect communication between client and server. You may need to edit or rename this file in order to fix ‘taking too long’ issues.

Windows hosts file

The hosts file is what maps domains to IP addresses. If you want to see for example how your site would look if you hosted on a different server, you would need to edit the hosts file.  If you have blocked website URLs or IP addresses in your hosts file, they might cause other sites to be blocked too, resulting in the page taking too long to load error.

The network adapter is not installed or is out of date

Drivers are very important for seamless communication between software and hardware. If your network driver is not up to date it may result in broken client-server communication.

Your browser contains corrupted files

Your browser may contain corrupted files. By reinstalling the web browser might solve this problem.

Theme incompatibility

If you are using WordPress, your theme incompatibility issues could be the reason for the ‘took too long to respond’ error. The only way to know whether it is your theme that is causing the issues is to change it to a default theme. If the error gets fixed, then you need to reinstall your theme.

Too much data in your database

If your database contains a lot of data, your site may take too long to retrieve all that data from your site.

Blockchain Technology explained

Hello People. This article makes you Blockchain Technology explained. A blockchain is a distributed database that is shared among the nodes of a computer network. It stores information electronically in digital format.

Blockchains are used in cryptocurrency systems, such as Bitcoin, for maintaining a secure and decentralized record of transactions. It guarantees the fidelity and security of a record of data and generates trust without the need for a trusted third party.

Main Features

  • Blockchain is a shared database. It differs from a typical database in the way that it stores information.
  • Blockchains store data in blocks that are then linked together via cryptography.
  • When data comes in, it is entered into a fresh block. Once the block is filled with data, it is chained onto the previous block, which makes the data chained together in chronological order.
  • Most common use of blockchain so far has been as a ledger for transactions. 
  • In Bitcoin, blockchain is used in a decentralized way so that no single person or group has control. All users collectively retain control.
  • Data entered is irreversible. Transactions are permanently recorded and viewable to anyone.
Blockchain Technology explained

Blockchain working process

The purpose of blockchain is to allow digital information to be recorded and distributed, but not edited. In this way, a blockchain is the foundation for immutable ledgers, or records of transactions that cannot be altered, deleted, or destroyed. This is why blockchains are also known as a distributed ledger technology (DLT).

Blockchain’s first widespread application in use was Bitcoin in 2009. In the years since, the use of blockchains has exploded via the creation of various cryptocurrencies, decentralized finance (DeFi) applications, non-fungible tokens (NFTs), and smart contracts.

Blockchain has three important concepts: blocks, nodes and miners.

Blocks

Every chain consists of multiple blocks and each block has three basic elements:

  • The data in the block.
  • A 32-bit whole number called a nonce. The nonce is randomly generated when a block is created, which then generates a block header hash. 
  • The hash is a 256-bit number wedded to the nonce. It must start with a huge number of zeroes (i.e., be extremely small).

When the first block of a chain is created, a nonce generates the cryptographic hash. The data in the block is considered signed and forever tied to the nonce and hash unless it is mined.  

Miners

Miners create new blocks on the chain through a process called mining.

In a blockchain every block has its own unique nonce and hash, but also references the hash of the previous block in the chain, so mining a block isn’t easy, especially on large chains.

Miners use special software to solve the incredibly complex math problem of finding a nonce that generates an accepted hash. Because the nonce is only 32 bits and the hash is 256, there are roughly four billion possible nonce-hash combinations that must be mined before the right one is found. When that happens miners are said to have found the “golden nonce” and their block is added to the chain. 

Making a change to any block earlier in the chain requires re-mining not just the block with the change, but all of the blocks that come after. This is why it’s extremely difficult to manipulate blockchain technology. Think of it as “safety in math” since finding golden nonces requires an enormous amount of time and computing power.

When a block is successfully mined, the change is accepted by all of the nodes on the network and the miner is rewarded financially.

Nodes

One of the most important concepts in blockchain technology is decentralization. No one computer or organization can own the chain. Instead, it is a distributed ledger via the nodes connected to the chain. Nodes can be any kind of electronic device that maintains copies of the blockchain and keeps the network functioning. 

Every node has its own copy of the blockchain and the network must algorithmically approve any newly mined block for the chain to be updated, trusted and verified. Since blockchains are transparent, every action in the ledger can be easily checked and viewed. Each participant is given a unique alphanumeric identification number that shows their transactions.

Combining public information with a system of checks-and-balances helps the blockchain maintain integrity and creates trust among users. Essentially, blockchains can be thought of as the scalability of trust via technology.

Optical Character Recognition in React

Hello People. This article discusses about Optical Character Recognition in React. OCR is very useful when you want to extract text from a scanned document on a browser. Applying OCR technology through a React application, you can upload your images in various formats and can apply OCR to extract text content so easily. 

How to achieve Optical Character Recognition in React?

We’ll use two third party libraries for different purposes. The first one is “tesseract.js”. It’ll allow us to run OCR easily with just a couple of lines of code. The second one is “react-images-upload”, it’ll allow us to upload images to the browser and access their locations easily.

Here we do a couple of new things and you may want to follow them carefully. We should put the code snippet above the return we need to create 3 states here to achieve different goals. The first state we have here is to take the image URLs from our ImageUploader component and save it for further processing, the second state is the one that we keep our OCR applied texts, and the third one is the one for loading logic.

Optical Character Recognition in React

onDrop function is called whenever a change happened in our ImageUploader component . So whenever a change happens like adding or removing the photos in our component this function will be fired up. It’ll take the argument we need in the second position after the onChange event is fired so we can simply bypass the first argument by putting “_” and take the second one. It has link/links for our images in it and it’ll bring the full latest list of links so whenever we get a list from our function we can safely put that in our array.

runOcr function seems tricky but in fact, it’s quite simple, we take our URLs state and run the following recognition script for each element. Tesseract recognize function takes at least 2 arguments, first is the URL and the second one is the target language, tesseract.js supports over 100 languages. After the requests resolve we take output text and add it to our current array. After we fire runOcr command we can setIsLoading to true so we can display our spinner.

Cost of developing an IOT app

Hello People. This article discusses about Cost of developing an IOT app. From 2020, Internet of Things software development is in huge demand.

Major factors that influence your IOT development budget:

  • Number and complexity of IoT app features 
  • IoT UX complexity
  • UI requirements (number of screens, style guide)
  • App security level
  • Device types on which it should work
  • Operating system and API integrations

In addition to the above factors, IoT requires building hardware from scratch or existing hardware optimization. For this you need to conduct research regarding existing hardware options and then test and choose that one that may be suitable for your IoT business idea execution. In the case of creating hardware from scratch, the process includes lots of costly stages such as Analysis, Modeling, Prototyping, and Testing. 

Cost of developing an IOT app

You will also need IoT network and middleware. Middleware is about third-party device integration and digital ecosystem maintenance.  The type of application and its complexity also may vary. A Simple IoT app has limited device connection options and only basic features. The budget may start from $30,000

A Sophisticated IoT app could have a large number of advanced features. It includes APIs, GPS tracking, payments, and other smart device integrations. This may include sync, third-party API, and security tool integration. The product development should be estimated at $50,000 as a minimum.

The hourly rates of programmers also matter. Development outsourcing remains the most cost-effective solution, as it allows you to choose specialists from the global talent pool. At the same time, there are also outsourcing risks with respect to the failure of your project execution completely or partly as a separate factor. IOT developers charge 100 to 150 dollars per hour.

Compared to other sorts of digital development, building an IoT app is a new area where lots of challenges haven’t yet got specific solutions. IoT development involves creating a unique digital infrastructure. It is hard to predict the final cost, as there are numerous factors that may influence it. Hardware issues, difficulties with API integration, maintenance plan, unique solution promotion are among them.

IoT application in the Environmental Sector

Hello People. This article discusses about IoT application in the Environmental Sector. Using IoT, we can monitor and control our environment closely. We can also use this technology to predict environmental disasters. In that way we can implement damage-control early-on.

We can use real-time data sets to spot substantial contamination early on. Using IoT-enabled technology, such as drones, GPS sensors, animals can be detected and tracked in real-time. A potential outbreak on infectious diseases can be prevented much more efficiently. Livestock can be equipped with RFID chips, and RFID scanners. 

We can develop an IoT-system that monitors wastewater and provides a system-wide reporting solution for potential sewer overflow or discharge. It depends on water level sensors located inside manholes. These IoT-sensors relay information to a server that alerts users via an App or SMS about the potential spill-over and overflow.

IoT application in the Environmental Sector

Businesses can implement IoT systems and AI technology, to monitor their hardware. If a part has turned faulty, the IOT system may redirect the consumer to the nearest authorized repair shops.

Using IoT technology, different servers and data centers can be connected. Data centers connected through IoT technology will be able to monitor their servers in real-time . As a result money and energy can be saved, whenever the server load is lower than usual.

Many drivers in congested cities waste a considerable amount of time and money trying to find a parking space. Cities can employ IOT systems that automatically alert nearby drivers of empty parking spaces.

IoT technology can play a crucial role in smart agriculture. By attaching different sensors to crops and trees, one can gain insightful data on hydration level, nutrient levels, diseases etc. This may also decrease the use of chemical fertilizers and pesticides.
