‘Link in Bio’ Rumor Not True, Says Instagram Chief

The head of Instagram, Adam Mosseri, has taken to the platform to address rumors that writing “link in bio” negatively affects reach.

Saying “link in bio” in a post is very common, as Instagram does not allow links in posts, but users can include them in the bio section of their profile.

There has been speculation that including a “link in bio” in a caption will reduce a post’s visibility. But Mosseri categorically says that the rumors are unfounded.

“You’re more than welcome to say ‘link in bio’, it will not affect your reach one way or the other,” Mosseri says in an Instagram post. “Adding a link to your bio can be super useful, I do it all the time, so please feel comfortable doing it as much as you like.”

Over 184 million passwords and account credentials from major companies like Apple, Microsoft, Google, and others have been leaked in a massive data breach.

Over 184 million passwords and account credentials from major companies like Apple, Microsoft, Google, and others have been leaked in a massive data breach.

Cybersecurity researcher Jeremiah Fowler found a database containing usernames, passwords, emails, and URLs for a wide range of apps and websites, including Facebook, Instagram, Snapchat, and more. The leak also exposed sensitive information from government sites, health platforms, and bank accounts.

What makes this breach especially dangerous is that the leaked file was not encrypted, meaning millions of pieces of personal data are available in plain text. Without any protection, cybercriminals can easily misuse this sensitive information.

WhatsApp to Stop Working on These Android Phones Starting January 2025: Check the Full List

2024-12-26T21:49:00.000-08:00

With the introduction of new features and AI support, WhatsApp will no longer be compatible with older Android phones, as their outdated hardware can't support the latest updates.

WhatsApp is set to stop working on millions of Android phones still running outdated software. As Meta continues to introduce new features and enhancements, including AI support, it is phasing out devices that can’t support these advancements, including older iPhones.

The Android KitKat version, which was released over a decade ago, will no longer be supported by WhatsApp starting January 2025. If you’re still using a phone with Android KitKat, it’s time to consider upgrading to a newer device in order to keep using the messaging app.

Many might wonder why anyone would still be using a phone with Android KitKat, but the fact that WhatsApp has continued to support the OS until now suggests there was a reason to do so. However, come 2025, this will no longer be the case, and the platform’s decision to phase out support means it’s time for users to finally make the upgrade.

WhatsApp to Stop Working on These Android Phones
Starting January 1, 2025, WhatsApp will no longer support a range of Android phones, including popular models from brands like Samsung, LG, Sony, and even HTC (yes, they’re still around!). If you’re using one of these older devices, it’s time to consider an upgrade to stay connected on the platform.

Mark Zuckerberg explains tech layoffs

2024-04-04T23:46:00.000-07:00

Mark Zuckerberg explains tech layoffs

The tech industry is moving towards being more efficient by having fewer workers. This change is due to the economy after the pandemic and the use of AI technology. Mark Zuckerberg believes that companies are laying off workers because they've seen the advantages of having smaller teams. This decision is a response to changes in what consumers want and difficulties created by the pandemic. The push towards using new technologies and the need to stay competitive also encourage this trend.

Zuckerberg's Perspectives:

Pandemic-induced Hiring and Subsequent Layoffs: The initial surge in e-commerce during the pandemic led to increased online advertising revenues, prompting tech companies to expand their workforce. However, as normalcy resumed, the decline in growth rates revealed an overextension in hiring, leading to the first wave of layoffs.
Shift Towards Operational Efficiency: Post-pandemic, the focus shifted from addressing overtiring to recognizing the benefits of a streamlined operation. Companies, including Meta, embarked on efficiency drives, reducing staff and management layers to simplify structures and enhance agility.
Strategic Integration of AI Technologies: Despite downplaying AI's role in Meta's decision-making, the tech industry's restructuring efforts increasingly emphasize leveraging AI technologies to enhance efficiency and competitiveness.

The wave of layoffs in the tech sector, as seen through Zuckerberg's lens, is not merely a reactionary measure to past over hiring but a strategic move towards operational efficiency. This shift is influenced by the lessons of the pandemic, the potential of emerging technologies, and the dynamics of competition, all of which shape the evolving landscape of the tech industry.

How to finding cricket match fixing?

2023-09-17T22:26:00.001-07:00

How to finding cricket match fixing?

Detecting cricket match-fixing is a serious matter that typically falls under the jurisdiction of law enforcement agencies, sports governing bodies, and anti-corruption units. Match-fixing is illegal and unethical, and it undermines the integrity of the sport. If you suspect match-fixing or want to report suspicious activities related to cricket matches, here are some steps you can take:

1. Contact the relevant authorities
- In many countries, there are dedicated sports integrity units or anti-corruption units that investigate such matters. For international cricket, the International Cricket Council (ICC) has its own Anti-Corruption Unit (ACU).
- You can report your concerns to these organizations through their official websites or contact information. They often have anonymous reporting mechanisms to protect whistleblowers.
2. Gather evidence (if safe to do so)
- If you have concrete evidence or information related to match-fixing, such as emails, text messages, or recordings, preserve this evidence. Do not tamper with it or share it with anyone other than the relevant authorities.
3. Do not confront individuals involved
- Do not attempt to confront or confront individuals who you suspect are involved in match-fixing. This can be dangerous and may hinder investigations.
4. Be cautious about sharing suspicions
- Be careful when discussing your suspicions with others, as false accusations can harm innocent individuals' reputations.
5. Support clean and fair cricket
- Encourage and promote the values of fair play, integrity, and honesty in cricket. Support efforts to eliminate corruption from the sport.
- 6. Suspicious Betting Patterns
- One of the primary indicators of match-fixing is unusual betting patterns. Bookmakers and betting agencies closely monitor betting markets for any irregular or suspicious betting activities. Large sums of money placed on specific outcomes or sudden changes in odds can raise red flags.
- 7. Player Behavior
- Authorities pay attention to the behavior of players, umpires, and team officials. Sudden changes in performance, unusual decisions during a match, or suspicious actions off the field can all be signs of match-fixing.
- 8. Informants and Whistleblowers
- Sometimes, individuals with knowledge of match-fixing come forward as informants or whistleblowers. This could be players, team officials, or others involved in the sport who want to expose corruption.
- 9. Sting Operations
- Law enforcement agencies may conduct sting operations to catch individuals involved in match-fixing. This often involves undercover agents posing as bookies or corrupt individuals to gather evidence.
- 10. Communication Records
- Investigators may track communication records, such as phone calls, text messages, or emails, to identify suspicious conversations or exchanges of information related to match-fixing.
- 11. Financial Records
- Money trails and financial transactions are essential for tracking illegal payments made to players or officials involved in match-fixing. Financial investigations can help uncover the flow of illicit funds.

What is Marketing 5.0 : Technology for humanity

2023-01-03T02:52:00.004-08:00

What is Marketing 5.0

Definition of Marketing 5.0

A marketing tactic called "Marketing 5.0" positions technology as a tool for improving humankind. Now is the time when humans and technology work together to develop consumer experiences. It's a time for radical shifts that call for agility and a quantum leap.

We are all prompted to change by a marketing strategy that operates in the digital arena. Transformation is a given, and it should be managed agilely. Consumers need to be fully surrounded by brands since they are an essential part of their lives. If brands can develop symbolic meanings that align with consumer beliefs, they will be enduring.

Experience is what matters because we live in a "Experience Economy" today. Impressive encounters will result in connections that may strengthen entanglements.

Marketing Approaches

Marketing 1.0 is a product-centric marketing. The main focus is on a product.
Marketing 2.0 is a consumer-oriented marketing. The main focus is on a consumer.
Marketing 3.0 is a values-driven marketing. The main focus is on a person. Companies move from a consumer orientation to a person orientation and when the pursuit of profit is combined with corporate responsibility. Marketing 3.0 is designed, like Marketing 2.0, to meet the needs of consumers, but companies that use this type of marketing have a mission, vision, and values that are important to the world as a whole.
Marketing 4.0 is a movement from traditional to digital. This marketing approach combines online and offline interaction between companies and consumers.
Marketing 5.0, according to the authors’ definition, is the application of human-mimicking technologies to create, communicate, deliver, and enhance value across the customer journey. It combines elements of the two previous approaches: Marketing 3.0 with a human orientation and Marketing 4.0 with a technology orientation.

Marketing 5.0 Main Technologies

The main technologies for using Marketing 5.0 are AI – artificial intelligence, NLP- natural language processing, sensors, robotics, MR- mixed reality (includes AR – augmented reality and VR – virtual reality), IoT, and blockchain. The authors call these advanced technologies the next tech. The next tech is those technologies that will become mainstream in the next decade. All these means are aimed at imitating human learning methods. The emergence of the next tech is due to six factors: computing power, opensource software, the Internet, cloud computing, mobile devices, and big data.

Artificial Intelligence. Artificial intelligence allows companies to conduct marketing research in real time. This rapid response helps them to perform customization and personalization in product recommendations, pricing, and content marketing campaigns.
Natural Language Processing (NLP). NLP is the training of machines to reproduce the human way of communication, both written and spoken language. Voice assistants will compare products and give recommendations on brands to buy based on previous experience, the more products purchased, the more accurate the offer.
Sensor Tech. In addition to text and speech recognition, computers also learn from image and face recognition. This skill allows you to scan an image and search for similarities on the Internet or in a database.
Robotics. A growing trend, robot process automation (RPA), involves software robotics.
Mixed Reality (MR). MR includes virtual and augmented reality. MR, first of all, is aimed at the entertainment industry, as they are focused on imitating the human imagination. But MR’s capabilities are not limited to this, and some of the most forward-thinking brands are already using this technology to improve the quality of customer service.
Internet of Things (IoT) and Blockchain. IoT refers to the interrelation of machines and devices that interact with each other. Blockchain is an open and distributed accounting system, it records encoded data on the network. The block contains all past transactions. Once a block is completed, it can never be changed and will give way to the next block in the chain.

What is Blockchain Technology? How does a blockchain work?

2022-10-08T01:40:00.002-07:00

What is Blockchain Technology? How does a blockchain work?

Blockchains are incredibly popular nowadays. But what is a blockchain?

How do they work, what problems do they solve and how can they be used?

Like the name indicates, a blockchain is a chain of blocks that contains information.

This technique was originally described in 1991 by a group of researchers and was originally intended to timestamp digital documents so that it’s not possible to backdate them or to tamper with them. Almost like a notary.

However it went by mostly unused until it was adapted by Satoshi Nakamoto in 2009 to create the digital cryptocurrency Bitcoin. A blockchain is a distributed ledger that is completely open to anyone.

They have an interesting property: once some data has been recorded inside a blockchain, it becomes very difficult to change it. So how does that work?

Well, let’s take a closer look at a block. Each block contains some data, the hash of the block and the hash of the previous block. The data that is stored inside a block depends on the type of blockchain. The Bitcoin blockchain for example stores the details about a transaction in here, such as the sender, receiver and amount of coins. A block also has a hash. You can compare a hash to a fingerprint. It identifies a block and all of its contents and it's always unique, just as a fingerprint. Once a block is created, it’s hash is being calculated. Changing something inside the block will cause the hash to change. So in other words: hashes are very useful when you want to detect changes to blocks.

If the fingerprint of a block changes, it no longer is the same block. The third element inside each block is the hash of the previous block. This effectively creates a chain of blocks and it’s this technique that makes a blockchain so secure.

Let's take an example. Here we have a chain of 3 blocks. As you can see, each block has a hash and the hash of the previous block. So block number 3 points to block number 2 and number 2 points to number 1. Now the first block is a bit special, it cannot point to previous blocks because it's the first one. We call this the genesis block. Now let's say that you tamper with the second block. This causes the hash of the block to change as well. In turn that will make block 3 and all following blocks invalid because they no longer store a valid hash of the previous block. So changing a single block will make all following blocks invalid. But using hashes is not enough to prevent tampering.

Computers these days are very fast and can calculate hundreds of thousands of hashes per second. You could effectively tamper with a block and recalculate all the hashes of other blocks to make your blockchain valid again. So to mitigate this, blockchains have something called proof-of-work. It's a mechanism that slows down the creation of new blocks. In Bitcoins case: it takes about 10 minutes to calculate the required proof-of-work and add a new block to the chain. This mechanism makes it very hard to tamper with the blocks, because if you tamper with 1 block, you'll need to recalculate the proof-of-work for all the following blocks. So the security of a blockchain comes from its creative use of hashing and the proof-of-work mechanism. But there is one more way that blockchains secure themselves and that's by being distributed.

Instead of using a central entity to manage the chain, blockchains use a peer-to-peer network and anyone is allowed to join. When someone joins this network, he gets the full copy of the blockchain. The node can use this to verify that everything is still in order. Now let's see what happens when someone creates a new block. That new block is send to everyone on the network. Each node then verifies the block to make sure that it hasn't been tampered with. If everything checks out, each node adds this block to their own blockchain. All the nodes in this network create consensus. They agree about what blocks are valid and which aren't. Blocks that are tampered with will be rejected by other nodes in the network. So to successfully tamper with a blockchain you'll need to tamper with all blocks on the chain, redo the proof-of-work for each block and take control of more than 50% of the peer-to-peer network.

Only then will your tampered block become accepted by everyone else. This is almost impossible to do! Blockchains are also constantly evolving. One of the more recent developments is the creation of smart contracts. These contracts are simple programs that are stored on the blockchain and can be used to automatically exchange coins based on certain conditions. More on smart contracts in a later video. The creation of blockchain technology peaked a lot of people’s interest. Soon, others realized that the technology could be used for other things like storing medical records, creating a digital notary or even collecting taxes. So now you know what a blockchain is, how it works on basic level and what problems it solves.
