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


The third generation of the internet has now firmly taken hold in ern retelling of Web history. Web 3.0 will usher in a new era of decentralized blockchain-based architectures as we transitioned from decentralized protocols (Web 1.0) to centralized, monopolistic platforms (Web 2.0).

With Web 3.0 as the prevailing narrative, the grasp of power will dissipate from a small number of powerful Web 2.0 firms and return power to the people.

In contrast to today, when tech giants dominate the platforms, in Web3, users will have ownership shares in platforms and applications.

Significance of Web 3.0

The vast majority of designers and builders will use cutting-edge tools, integrate into autonomous organizations, and take part in this new economy.

Decentralized Autonomous Organization is the guiding principle of Web 3. (DAO). Users will be able to govern their own data on a decentralized, fair internet thanks to Web3.

This would get rid of the extortionate rents charged by the big platforms and get people away from the fundamentally faulty ad-based monetization of the user-generated data paradigm that has come to define the current digital economy.

Prerequisite for Developing Web 3.0 Architecture

The current architecture, which has a front-end, intermediate layer, and back-end, will need to be modified for Web 3.0 from a technological standpoint.

For processing blockchains, persisting and indexing data in blockchains, peer-to-peer interactions, and other tasks, will require backend solutions.

In a similar vein, managing a backend with a blockchain will be required of the middle layer, also known as the business rules layer.

Evolution of the Web Web 1.0-World Wide Web Begins Web 2.0-The Social Web

There are a few factors to take into account when describing web 2.0. Internet programs that let users communicate, cooperate, and express themselves online are referred to by the phrase. It’s essentially a better version of the first global web, marked by the shift from static to dynamic or user-generated content, as well as the rise of social media.

Rich web applications, web-oriented architecture, and the social web are all part of the Web 2.0 paradigm. It refers to changes in the way web pages are designed and utilized by people, without any technical changes.

“Web 2.0 is the business revolution in the computer industry caused by the move to the internet as a platform, and any attempt to understand the rules for success on that new platform.”–     Tim O’Reilly.

Web 2.0 can be described in three parts:

Rich Internet application (RIA): It specifies if the experience delivered from the desktop to the browser is “rich” in terms of graphics, usability/interactivity, or features.

Web-oriented architecture (WOA): It specifies how Web 2.0 applications disclose their functionality so that other apps can use and integrate it, resulting in a significantly richer range of applications.

Key Features of Web 2.0

Folksonomy: Users can collaboratively classify and find information (e.g. “tagging” of webpages, images, videos, or links) using a free classification system.

Software as Service (SaaS): APIs were built by Web 2.0 sites to facilitate automated usage, such as by a Web “app” (software application).

Mass Participation: With nearly universal web access, concerns are being differentiated beyond the conventional Internet user base (which tended to be hackers and computer enthusiasts) to a broader range of consumers.

Use Case Applications of Web 2.0

Hosted Services (Google Maps)

Web Applications (Google Docs)

Video-Sharing Sites (YouTube)

Wikis (Media wiki)

Blogs (Word press)

Interactive Social Networking/Media (Facebook)

Micro Blogging (Twitter)

Pros of using the Web 2.0

Information is available at any time and in any location.

A wide range of media. (Images, Videos, Web Pages, Text/Pdf) It– Very user-friendly.

Learners can actively participate in the creation of knowledge.

Has the ability to form dynamic learning communities.

Everyone is both the author and the editor, and every edit can be monitored.

Simple to use.

The wiki is updated in real-time, and it provides researchers with extra resources.

It allows for real-time communication.

Cons of using Web 2.0

People rely heavily on the internet to communicate.

It is keyword driven.

Failure to remove material that is no longer relevant.

Many con artists and hackers.

Intelligence is lacking.

Web 3.0-The Decentralised Web

Web 3.0 is the third generation of internet-based services or an intelligent web. The expression was created in 2006 by John Markoff. Although it is typically understood to be a reference to the semantic Web, he continued, “There is no easy consensus about what Web 3.0 means”.

The semantic Web, while not a more accurate term, refers to technology that improves Internet use by comprehending the meaning of what users are doing rather than merely the way pages link to each other.”

With significant developing technology trends like semantic web, data mining, machine learning, natural language processing, artificial intelligence, and other such technologies centered on information that is machine-assisted, Web 3.0 is expected to be more connected and smarter.

The web as a whole should be better designed to cater to a user’s interests and needs. Self-descriptions or similar strategies can be used by developers and authors individually or in partnership to ensure that the information produced by the new context-aware application is meaningful to the user.

Key Concepts in Web 3.0

Decentralization: “To post anything on the web, no approval from a central authority is required; there is no central controlling node, and hence no single point of failure…and no ‘kill switch!” This also entails freedom from censorship and surveillance on an ad hoc basis.”

Bottom-up design: “Rather than being written and controlled by a small group of experts, the code was created in full view of everyone, enabling maximum participation and experimentation.”

Key Features of Web 3.0

Decentralization: This is a fundamental principle of Web 3.0. In Web 2.0, computers search for information using HTTP in the form of unique web addresses, which are stored in a fixed location, usually on a single server. Because Web 3.0 allows information to be retrieved based on its conten be kept in several locations at the same time, making it decentralized. This would deconstruct the vast databases currently maintained by internet behemoths like Meta and Google, giving people more power. Users will retain ownership control of data generated by disparate and increasingly powerful computing resources, such as mobile phones, desktop computers, appliances, vehicles, and sensors, with Web 3.0, allowing users to sell data generated by their devices.

Semantic Web: Let’s take a step back and define semantics first before creating the semantic web. The study of how words relate to one another is known as semantics. The semantic web is a technology that enables computers to interpret massive amounts of Web data, including text, grammar, transactions, and linkages between people.

3D Graphics: Compared to the straightforward, two-dimensional web, Web 3.0 will provide a more believable, three-dimensional cyberworld. Online gaming, as well as Web 3.0 websites and services like e-commerce, real estate, tourism, and other industries, will benefit from a new degree of immersion thanks to 3D visuals.

Trustless and permissionless: Web 3.0 will be trustless (i.e., the network will allow members to engage directly without going via a trusted intermediary) and permissionless, in addition to being decentralized and built on open-source software (meaning that anyone can participate without authorization from a governing body). As a result, Web 3.0 applications will run on blockchains, decentralized peer-to-peer networks, or a combination of both, and will be referred to as dApps (decentralized apps).

learning: Through technologies based on Semantic Web ideas and natural language processing, machines will be able to understand the information in the same way that people do in Web 3.0. Machine learning will also be used in Web 3.0, which is a branch of artificial intelligence (AI) that combines data and algorithms to mimic how humans learn while continuously improving accuracy. These capabilities will allow computers to deliver faster and more relevant results in a variety of sectors, such as medical research and novel materials, as opposed to the current focus on targeted dvertising.

Connectivity and ubiquity: Information and content are increasingly accessible and omnipresent with Web 3.0, which can be accessed by many applications and a growing number of daily objects connected to the internet, such as the Internet of Things.

Use Case Applications of Web 3.0

Social Networks: Social networks have a significant impact on how we live our lives and change the way we connect, communicate, and build communities. The new generation of social networks, however, is not without issues. They have internal agendas, are restrictive, and are censored. Governments of major companies may also utilize social networks to try and shape and control the opinions of their users. The functioning of the social network will be entirely altered by Web 3.0. Social media networks won’t be subject to any restrictions thanks to the implementation of blockchain. Regardless of geographic restrictions, anyone can join.

Exchange Services: As they offer a flawless user trade experience without worrying about any hacks or transparency, decentralized exchanges are progressively gaining favor. This also implies that there is no central authority and no owner-side conflict of interest. To streamline their services, they primarily use a variety of decentralized finance tools. As we already know, Web 3.0 is all on decentralized exchange and trust.

Messaging: Since the day we first started using the internet, messaging has been a part of our daily life. Well, for the majority of us, the choice is between Facebook Messenger and WhatsApp. One other type of messenger is Telegram, which is mostly used by businesses, startups, and other types of professional activity. On the other side, the government also frequently uses centralized systems to manage its network of intelligence to trace down signals.

Storage: The storing of data involves a lot of ingenuity. However, Web 3.0 technologies like blockchain and big data can transform the way data is now stored. As common users, we store data online on Google Drive and other cloud storage services. For the businesses, it’s a whole different scenario because they prefer a more reliable and centralized system to keep their important data.

Insurance and Banking: One of the most contaminated sectors of our society is the insurance and banking industry. For instance, is managed according to the profit-making mindset. The chains of negativity are also present in the banking industry. Overall, it is safe to state that the current system is flawed and that it must be made more open and secure if people are to prosper inside it. Blockchain technology has the potential to revolutionize both the banking and insurance industries. This technology has a wide range of applications, and its effects are more apparent than initially anticipated. Transparency, security, and retractability are just a few of the blockchain capabilities that will be utilized in the transformation. This means that fraud in the banking or insurance industries will not be conceivable.

Streaming (Video and Music): The streaming sector is significant. Additionally, it is predicted to expand more quickly in the next years. You are already familiar with the major players in our area as a user.

Remote Job: Given that we prefer working from home over being in an office, it is rather fascinating to observe where we are headed. Whatever the causes, the centralized remote job platforms fall short of expectations. These issues can easily be solved by decentralized remote job/freelance networks.

Browser: Using a web browser, we browse the Internet. We require a browser that adheres to the decentralized Web’s philosophical aspect in order to explore web 3.0. In terms of safeguarding users, the most recent browsers are also not entirely secure. Computers can become infected when users visit infected websites. If they are not sufficiently constructed in accordance with current security standards, browsers can also leak information. Your browser, for instance, keeps data on your location, hardware, software, connection, social media accounts, and more. The add-ons that these contemporary browsers provide make the users vulnerable as well. The answer is to utilize a decentralized browser that uses blockchain technology to create a better ecology.

Pros of using the Web 3.0

Anti-monopoly and Pro-privacy: Web 3.0 will provide the internet with a pro-privacy and anti-monopoly framework. It won’t encourage the use of centralised platforms. In essence, a full paradigm shift will occur, with decentralisation and privacy as the main themes. The middleman won’t understand the value or need of such a platform.

Secure Network: Web 3.0 features will be safer than those of its forerunners. Decentralization and distributed nature are two reasons that enable this. It will be challenging for hackers or exploiters to access the network. Each of their operations can be monitored and retracted within the network if they are able to do so. Without centralization, it will also be more difficult for hackers to seize total authority over a company.

Interoperability: It is a crucial component of Web 3.0. It will be simpler for applications to function across various platforms and devices, such as TVs, cellphones, smart roadways, and so on, with a decentralised network. The creation of Web 3.0 apps will be simple for developers.

No Interruption in Service: Service interruptions are less likely to occur in distributed systems. It is challenging for attempts at distributed denial of service (DDoS) or other types of service breakdown to have an impact because there is no central entity for functioning. As a result, Web 3.0 is a fantastic platform for sharing data and essential services without having to worry about service disruption.

Permissionless Blockchains: Blockchains without a requirement for a central authority are to be powered by Web 3.0. By creating an address, everyone can join the blockchain and take part. Access to individuals who are historically excluded owing to their gender, income, location, and other factors is made possible via permissionless blockchains. Although there are other blockchains with chúng tôi implies that Web 3.0 won’t be subject to any limitations.

Semantic Web: The semantic web’s features will be hosted by Web 3.0 as well. The previous set of Web 2.0 technologies have been replaced by the semantic Web. It makes it possible to transfer data across many platforms, systems, and community borders. It will serve as a link between various systems and data formats. We will be able to share and use the internet more than ever by utilising the semantic Web.

Cons of using the Web 3.0

Ownership concerns: With internet providers under government control, the internet will still not be decentralized.

Existing website owners will be compelled to upgrade: With the change in the cost model, some services may no longer be free.

Tough to regulate: Newcomers may struggle to understand Web3.0

Easier access to one’s personal and public data: Without privacy policies, it will be easy to gain access to someone’s private and confidential user information.

Comparison between Web 2.0 and Web 3.0

Web 2.0 Web 3.0

Centralized. Application delivery, cloud services, and platform are governed and operated by centralized authorities. Decentralized. Edge computing, peer-to-peer, and distributed consensus increasingly become the norm in Web 3.0.

Fiat currency. Payments and transactions occur with government-issued currency, such as $USD. Cryptocurrency. Transactions can be funded with encrypted digital currencies, such as Bitcoin and Ethereum.

Cookies. The use of cookies helps to track users and provide personalization. NFTs. Users can get unique tokens that are assigned value or provide some form of the perk.

CSS and Ajax. Web 2.0 is defined by layout technologies that provide more dynamic control than Web 1.0. AI. Smarter, autonomous technology, including machine learning and AI, will define Web 3.0.

Relational databases. Databases underpin the content and applications of Web 2.0. Blockchain. Web 3.0 makes use of blockchain immutable ledger technology.

Social networks. Web 2.0 ushered in the era of social networking, including Facebook. Metaverse worlds. With Web 3.0, metaverse worlds will emerge to meld physical, virtual, and augmented reality.

Future for Web 3.0

Web 3.0 is still in the process of being defined. As a result, there are many unknowns regarding what Web 3.0 will eventually look like.

The IPv4 address class, which has a limited amount of web addresses, is used by both Web 1.0 and Web 2.0. In the Web 3.0 era, IPv6 offers a bigger address space, allowing more devices to have their public IP addresses.

Web 3.0’s focus on decentralization, automation, and intelligence will likely continue to be the foundation for what comes next as it evolves and is defined.


As a last thought, I’d want to leave everyone with another example that started this learning journey. According to an analogy from the movie industry, if Web 1.0 represented black-and-white movies, Web 2.0 would be the age of color/basic 3D, while Web 3.0 represents immersive experiences in the metaverse. In the same way that Web 2.0 dominated the global business and cultural landscape in the 2010s, it seems that Web 3.0 will now take the lead in the 2023s. Facebook changing its name to Meta on Oct. 28, 2023, could prove to be an early sign that Web 3.0 is gaining traction.

The most significant aspect of Web 3.0 is that it improves security, trust, and privacy. Many people refer to Web 3.0 as the “decentralized web,” because it will rely heavily on decentralized protocols. Web 2.0, on the other hand, is still the foundation for many of the web apps we use today. Is it possible that Web 3.0 will transform the popular programs you use today? Learn about Web 3.0 and make your conclusions.

Rockmelt: The Facebook Of Web Browsers

A new Web browser, Rockmelt debuts in limited beta Monday and aims to help you keep tabs on your Facebook friends and your favorite sites, and make your Web searches faster. Backed by Netscape founder Marc Andreessen, Rockmelt was first reported on by The New York Times

A year later, and Rockmelt appears to be nothing more than another social networking-focused browser similar to Flock. Just like Flock, Rockmelt incorporates your social networking activity into browser sidebars so you can stay up to date on your friends’ activities while you browse other parts of the Web. Unlike Flock, however, Rockmelt features a single sign-on profile tied to your Facebook ID that you can carry with you using any computer running Rockmelt. Both browsers are based on Chromium, Google’s open source project that is basically a test ground for Google Chrome.

If you’d like to try out Rockmelt, you can sign up for the limited beta at chúng tôi by signing in with your Facebook ID.

I haven’t had a chance to get my hands on Rockmelt yet, but here’s a look at some of the key features of the world’s latest social-focused browser.

All About Facebook

All of this personalized information is saved on Rockmelt’s servers so that you can access it by logging into the Rockmelt browser from any computer. Rockmelt does not, however, save your Web searches or browsing history, according to an interview with Rockmelt co-founders Eric Vishria and Tim Howes by blogger Robert Scoble. The company also says that all of your personal data is stored as an encrypted bundle on its servers to keep it private. It’s not clear if Rockmelt has the ability to decrypt your data, but the company does say they are not interested in your information for the purposes of ad targeting.

It should be noted that in addition to being an investor in Rockmelt, Andreessen also sits on Facebook’s board of directors.

Facebook Friends on the Left

On the left side of your browser window is a thin sidebar that lists the Facebook profile pictures of your “favorite” Facebook friends. It’s not clear how Rockmelt determines which people are your favorite Facebook friends or how you can change that setting.

Favorite Sites on the Right

On the other side of your browser window is a second sidebar where you can get feeds from your favorite sites including news sources such as The New York Times or CNN. You can also add other social networking sites such as Twitter and Facebook. Rockmelt didn’t explain what the differences are between the Facebook updates on the left side and right side of the browser. If I had to guess, however, I would say that including Facebook in your right sidebar shows you updates from your newsfeed, while the left sidebar features select updates from your “favorite” Facebook friends.

Rockmelt Search

Rockmelt features two search boxes: a regular Chrome-style Omnibox and a special Rockmelt search field. Rockmelt’s search feature is designed to help you get to your Web results faster, and the company said it wanted to make search as “simple as leafing through a magazine.”

Let’s say you were searching for information about flu shots, and the top search results were links to the Center for Disease Control, Wikipedia, and a CNN news item followed by four other site links. Rockmelt would display the results just as you would see them in Google in a drop down menu. You would then see a preview of each site in the main browser window as you scrolled through your results in the drop down menu. So you could preview the content from the CDC, Wikipedia, CNN, and so on until you find what you’re looking for.

If you just want typical Google results then you can use the Omnibox instead of Rockmelt’s dedicated search box.

Rockmelt appears to be an interesting take on integrating social features into your Web browsing and the new search feature could be useful. But Rockmelt has a tough road ahead to gain a foothold in an already crowded browser market that includes Apple’s Safari, Google Chrome, Microsoft Internet Explorer, Mozilla Firefox, Opera, Flock, and many others.

An interview with Rockmelt:

Market Meets Web, Web Meets Market.

Google has finally launched the Android Market’s web version, which, many (or most) of us had been praying for quite a long time. Although Google’s has kept the market very easy to use and get along with, you can start with this post to get the whole idea of the web version of the android market, its contents, exciting features and what it still lacks.

Signing In

Settings – “My Market Account”

Next thing you should do is checking out the “My market Account” tab wherein you will find two tabs:

Orders – It will simply list out apps currently installed on your phone — just like they show in “My Apps’ tab on your android market app on phone.

Settings – It will show android phones and tablets that are linked with your Google ID. You can change the name(s) of any device listed over there for proper and quick recognition. Also, you can select whether you want your device to be visible in the menus or not. (See screenshot below) If you select “Hidden in Menus” for any of your device here, it will not show in the drop down menus when you install apps or are using the ‘search options’ to select preferred device for search (more on this search function later). Suppose, you’ve one android phone only, and for that you select “Hidden in Menus”, then, when you hit the install tab, the pop-up will only say “There are no android phones associated with this account. Please sign in with a different account.” So, if you get that error, make sure you’ve select the option “Shown in Menus” under the settings and that your Google ID is same on phone and the web.

Downloading Apps from the Web Version of Android Market

Download app is the easiest thing with web version. Search for an app and simply hit the install button below it or the app’s description page where it’s on the left side. The app will be installed on your device Over-The-Air, meaning you don’t need to cable your phone to PC for that. Awesome, right?


You can browse the market category-wise too, by choosing the one of your interest from the left side. On the category page, You’ll be told about Top Paid Apps and Top Free Apps, while you can hit the ‘See more’ tab in the bottom left to get more of such apps.

Check out the video below where we’ve covered almost everything that’s useful, must-know, for you.

Exciting Features

Well, it’s easy to say which is the best thing market’s web version has done for us — it’s OTA (over-the-air) installation of apps. You hi the install button on your desktop’s browser and your phone would download the app and install it, right away, if it’s free. And if it’s a paid app, purchasing too is lot convenient when you’re using a web browser as compared to phone.

The third feature, although not exciting but more of a must-have, is a search function. Located at the top right corner, it allows you to search any app and let’s the installation process begin right from the search result’s page, which is very cool, since you don’t need to go to app’s page to download.

Another exciting stuff here is that you can now filter your search (see pic above) — hit the search option in the upper right corner and select whether you want only free or paid apps, based on relevancy or popularity and if you own and have attached more than one android device — which will be very much the case when android tablets hits the stores near us — you can sort the results to one of the several devices, by selecting your preferred gadget for the search from the drop down menu.

What it Still Lacks…

To an average user, almost everything has now been sufficiently covered just like the market app on phone, except that the latter has the “Just In” tab for discovering new apps which the web version lacks, and, there is no option to update the apps right from the web. Needless to say, the ‘update all’ feature is still missing from the web version, even if you’re on Froyo.

Bookmarking apps?

To a pro user, who wants variety of tools to sort out the best apps among the new ones (and wants to go beyond what Google recommends all the time), or want: user’s age-wise classification of apps based on Google profiles, country-wise classification like apple’s appstore, and many more countless features that don’t mean very much to a normal user, are still missing — but it’s not an insane thing, you know! These stuff might, in fact, complicate an average user’s experience, so we won’t blame Google or anyone here.

That’s it about the web version of the market.

Acunetix: Web Application Security Review

To launch a modern website requires a maze of proprietary programming, open-source libraries, and legacy features. Inspecting each component for vulnerabilities takes enormous time and labor resources unless the development or application security team can use automated tools.

Acunetix, an Invicti brand, delivers an easy-to-use web application security scanner with robust capabilities and high accuracy. For more about this product, see the following sections:

The web application security market is estimated to be over $6 billion dollars globally with a CAGR of more than 16%. As a division of a private company, Acunetix does not publicize full financials and external estimates vary wildly from $0.5 million to $10 million per year.

The hotly contested web application security market does not have any dominant products or solutions and is led by large competitors such as IBM Corporation, Oracle Corporation, Qualys Inc., Synopsis Inc., and Veracode.

Acunetix helps web application security teams to accelerate their hunt for vulnerabilities through the key features of their solution:

Automatically scan all websites, applications, and APIs for over 7,000 vulnerabilities

Schedule automatic scans to keep up to date 

In-depth scanning for a wide variety of web application components

Password-protected areas (using macros)

Multi-level forms

HTML5 & Javascript code

Single-page applications (SPA)

Blended dynamic (DAST) and interactive application security testing (IAST) scanning

Fast, accurate, and useful reports

Scan multiple environments simultaneously

Fast scans supply reports as soon as vulnerabilities are located

Vulnerability ratings and proof of exploit information help developers address issues quickly

Integrates with other tools

Web application firewalls (WAFs) to temporarily secure known vulnerabilities

Web application development workflow apps

Using any web application security tool should locate web code vulnerabilities and help teams eliminate them. Some of the specific benefits of using Acunetix include:

Acunetix automatically crawls the web URL and scans for potential web app components to test for vulnerabilities. The tool will scan multi-level forms, HTML5, JavaScript, password protected areas, and SPAs.

Web security scanning tools accelerate development time by reducing the time needed to hunt for bugs and other vulnerabilities. Acunetix automatically detects and identifies a wide range of vulnerabilities which will be ranked by severity and then sent to developers. This process helps developer teams to spend more time on fixing issues instead of finding them.

Using a web security scanner provides a record that can be used for internal and external reporting. Acunetix’s tool scans for a large number of vulnerabilities and can be set up for periodic automatic scans. These scans allow an application security team to continuously monitor for vulnerabilities and report on web application security status at any time.

CaterTrax’s team of 100 employees provides catering management software solutions for managing orders, inventory, and web commerce for 2,500 clients. With credit card and financial transactions flowing through their applications, CaterTrax needs to show compliance with PCI DSS regulations and keep client data secure.

In selecting Acunetix, CaterTrax can produce PCI compliance reports and maintain regular scanning for vulnerabilities without going over their budget. Benjamin De Point, VP of software development & hosting for CaterTrax admits that “Acunetix has helped make our application stronger and given our clients the assurance that their data is safe.”

Miles Technologies provides IT, software, marketing, and technology consulting services and needs to maintain a high reputation for security. Their web security team used to use several different security tools for vulnerability scanning and reporting, which regularly took more than a week to complete.

“Acunetix is our vulnerability scanning tool of choice for situations where information security is a real concern and confidence in safety is key,” said JP Lessard, president of software services at Miles Technologies. “Setup is quick, and the different types of reports save time when it comes to delivering security assessments to different executive and non-executive roles.”

As a component of the U.S. armed forces and a government agency, the U.S. Air Force (USAF) faces constant attacks and a limited budget. Their web security team needed to develop their own security checks and policies, scanning capabilities against a large range of technologies and vulnerabilities with accuracy. The solution also needed to be simple enough to be used by USAF trainees.

After testing against multiple competitors, Acutenix was selected because it met all of these requirements and also performed at a higher speed.

“Acunetix has played a very important role in the identification and mitigation of web application vulnerabilities. Acunetix has proven itself and is worth the cost,” said M. Rodgers of the USAF IT security team.

Invicti purchased both Netsparker, now branded as Invicti, and Acunetix. While both products remain separate, the best features of each were added to the other which makes these solutions more difficult to differentiate from each other. However, there remain important distinctions for any web application security team’s evaluation of web app security tools.

Both Invicti and Acunetix share many of the same vulnerability detection tools and false positive evaluators that led Invicti to score highly in independent third-party testing. Both tools stand apart from their competition in ability to identify vulnerabilities without the false positives that waste developer time.

Acunetix automatically detects websites, applications, and APIs for a web domain with each scan to ensure no vulnerabilities may be overlooked. Acunetix can also be set up to automatically perform periodic vulnerability scans, so the web application continues to be tested against updated vulnerability lists.

Acunetix narrows the scope for integration options and the user interface, so teams can install the tool faster and get up to speed quickly—as little as five minutes. Should a team decide they need to graduate to the more sophisticated Invicti solution, migration between products is very easy.

Acunetix provides quotes for pricing, but does not display prices on its websites. Free trials are available, and outside sources estimate the starting price to be $4,495 per year.

Acunetix delivers a robust web application security tool with powerful features, high accuracy, and quick speed for setup and scanning. Its simple integrations and user interfaces will be a blessing for smaller or less experienced teams looking to get started fast and deliver strong results.

Whatsapp Web Tips And Tricks

Keep your smartphone connected to the internet

To ensure you have an uninterrupted experience while using the WhatsApp Web client, we’d recommend keeping your smartphone connected to the Wi-Fi or mobile data at all times. WhatsApp Web does not function if your phone isn’t connected to the internet hence, make sure to keep Wi-Fi or mobile data on to receive or send messages via the WhatsApp Web client.

Use multiple WhatsApp accounts on the same PC

If you’re someone who has two or more WhatsApp accounts, then you’re in luck since there are a couple of ways to login and use multiple WhatsApp accounts on the same PC.

Method 1: Incognito Tab

Open an incognito tab on your browser and then visit the WhatsApp Web page and scan the QR code as usual to set up your account. Using an incognito tab would allow you to open multiple WhatsApp accounts on your PC and they would function as the normal WhatsApp Web client itself.

Method 2: Use a WhatsApp Web proxy

Read messages without Blue Ticks

You might be thinking that this is fairly simple and you could just turn off the Read receipts feature in WhatsApp settings, however, you could use another simple trick when using WhatsApp Web to read incoming messages and not show the Blue Ticks without the need to toggle of read receipts in the settings.

Simply follow these steps to use the trick:

Go to the WhatsApp Web tab

Open the chat window where you’re receiving or expecting to receive messages

Now open any other window e.g. File manager, notepad, etc.

Resize the window and make it fairly small and place it over the WhatsApp Web client tab in your browser

Now just wait for the incoming messages to show up on your WhatsApp Web client and read them

Since the window would be in the foreground, the browser would assume you’re working on a different app hence, the messages would not be marked as read. 

Boost volume or change playback speed of voice notes

Unfortunately, we can’t yet make voice calls via the WhatsApp Web client so for now, users have to make do with voice notes. While voice notes are pretty convenient and fun to use, at times the voice notes can be too long and you might not feel like listening to the whole voice note or the sender’s voice might be too soft for you to hear.

Luckily, there’s a cool Google Chrome extension that lets you adjust the volume of the audio note and even change the playback rate of the voice note. The extension lets you boost the volume all the way up by 100% and also lets you change the playback rate by 2x.

Transfer files from your phone to PC or vice versa

Yes! you read that right. It’s super easy to transfer files from your phone to your PC via the WhatsApp Web client, however, to be clear, this process does take place via the internet hence if you’re using your mobile data then, we’d suggest keeping track of the file size you want to transfer to avoid depleting the data or having to pay extra.

Keep in mind for this to work you’ll need a second WhatsApp account or a someone else’s phone to transfer the files from/to.

Open WhatsApp Web on your PC

Launch the app on your second WhatsApp account on your smartphone and send the file/image to the WhatsApp account which is logged in on the WhatsApp Web client on your PC

You could also do this the other way around to send a file/image from your PC to the smartphone

Simply download the received file and it would be stored on your smartphone/PC automatically

Change the background on WhatsApp Web

While using WhatsApp Web on your Chrome browser, you could install an extension which lets you change the background image while in the chat window as well as the background of the WhatsApp Web client.

To do this, simply download and install the W.Beautifier extension for Google Chrome and install the app.

The extension would show up towards the right side of the browser

Use can use any image on your PC/Mac as a background or wallpaper

Turn ON dark mode for better usability during night time

Adding emojis through your keyboard

To send emojis quickly on WhatsApp Web, head over to the text box inside a chat thread and type a colon (:) followed by a word (or a part of the word) that expresses that particular emoji you want to send.

For example, typing “:happy” will show you the following set of emojis:

Here’s what typing”:sad” will get you:

You will get this when you type “:heart” inside the text box:

Transform your emoticons into emojis

If you were born in and around the 90s, you would know that there weren’t emojis but emoticons where you typed a series of characters like a colon, semi-colon and brackets to express your emotion. There’s no shame, we’ve all used them. If you’re someone who still uses them, then you’ll be in luck as WhatsApp Web automatically converts your emoticons into emojis. Here’s a bunch of text smileys you can use to let WhatsApp convert them into emojis:

Web Therapy For Problem Preschoolers

Web Therapy for Problem Preschoolers Advice for parents from a long-distance observer

“He was running the show,” says Renee, who asked BU Today not to use her full name. “All day was spent trying to get him to do those two things he really needed to do.”

When her son turned three, a pediatrician recommended a neuropsychological evaluation, which yielded a diagnosis of attention deficit hyperactivity disorder (ADHD) and sensory processing disorder, with both conditions exacerbated by his temperament.

Renee was then handed a flyer for Boston University’s Center for Anxiety & Related Disorders (CARD), where Jonathan Comer, director of the early childhood intervention program, and Jami Furr, clinical director of the child program, are conducting trials on preschool oppositional defiant disorder. These behavioral therapy trials, supported by more than $1 million from the National Institutes of Health and the Charles H. Hood Foundation, address a condition that afflicts about 5 percent of preschool-aged children, and they help alleviate symptoms for up to 75 percent of participants.

Children with preschool ODD, says Furr, a postdoctoral associate in the College of Arts & Sciences psychology department, often also have ADHD. They refuse to comply with requests, like to annoy others, and may hit, bite, or throw things, and in more severe cases, they are physically cruel to animals. For obvious reasons, they are often kicked out of preschool. It’s no surprise that parents of such children “are often pretty defeated by the time they get to us,” she says.

Therapists typically use parent-child interaction therapy (PCIT) to treat preschool ODD in a clinical setting, where the therapist observes behind a one-way mirror and coaches parents, via an earpiece, as they play with their child. But such therapy isn’t an option for families who live far from clinics. Children in those families are particularly likely to be prescribed medicine with unfortunate side effects.

“What we’re seeing is skyrocketing rates of antipsychotic medications to treat aggression in young kids, in preschoolers even,” says Comer, a CAS research assistant professor of psychology, adding that such medications are associated with concerning metabolic, circulatory, and endocrine effects in young children.

As a postdoc at Columbia University, Comer had been part of an innovative team that provided PCIT to military families at Fort Drum in Jefferson County, N.Y., near the Canadian border. Distance (more than five hours by car) and the lack of appropriately trained local clinicians made traditional therapy impossible, so doctors turned to technology. They gave each family a web camera, scheduled meeting times, and conducted telehealth sessions online.

Back at BU, Comer and Furr—a husband and wife team with a toddler themselves—are halfway through five-year trials that compare the two options: clinical therapy versus telehealth, and telehealth versus delayed treatment. More than 20 families have signed up already, Comer says, and “it looks like the internet-delivered options are equally credible.” It’s possible, he says, that telehealth could be a lifeline for families of defiant preschoolers nationwide.

Before being admitted to the trials, families undergo a thorough assessment to determine whether their child has preschool ODD. Renee remembers when she and her three-year-old arrived at CARD and were put in a small observation room. “It was the first time ever that I was hoping he’d act out,” she says. She didn’t have to worry. Complying with the therapist’s request, she asked her son to take blocks and build a tower. Instead, he flipped the table, emptied nearby shelves, and started hitting her.

“You’re in!” the therapist told them.

Once families are “in,” they receive a technology packet with a webcam, a room microphone, a Bluetooth device, and a mobile hotspot, if necessary. Therapists schedule weekly one-hour sessions with the family, preferably when both parents are available, and everyone signs in through an encrypted site called WebEx.

Once they master those skills, families establish house rules (“No hitting, kicking, or spitting”) and start practicing a detailed timeout sequence when their child misbehaves. “This is really a learning process not only for the parents, but also for the children,” Furr says. “What we’re really emphasizing is consistency, predictability, and follow-through.”

Amy, another parent in the trial, says her son would never sit through a timeout. But after beginning therapy, he started putting himself in timeout for violating a house rule, like hitting his younger sister. “He wasn’t able to control the action, but he knew it wasn’t right,” she says.

The last stage is practicing timeout sessions outside the home, a realm most families avoid for fear of explosive and embarrassing tantrums. Therapists use walkie-talkies to coach parents as they practice their newfound skills in the middle of a restaurant, store, or park.

Most families master these skills within six months. And the earlier families start therapy, the better. “When left untreated,” Comer says, “these behaviors can snowball into more serious conduct problems and then antisocial problems later on in adulthood.”

Amy and her husband completed therapy last year, and she says they learned valuable lessons about parenting and have strengthened their relationship with their son. They still struggle at times, she says, but “we’re able to connect on a different level and understand each other.”

Meanwhile, Renee’s family is seven weeks into therapy, and they are already seeing results. Her son now asks for special playtime and even helps with simple tasks like putting away toys, which used to be a daylong battle.

“It saved our life,” Renee says. “As a family, we were being thrown apart. It’s been a savior for us to deal with him, understand him, and know that this kid has potential, and we want to help him achieve it.”
