There is a parallel universe to reality that provides creatives of all types a new space. These are virtual worlds that are building a community within ecosystems that run over the Internet. You can think of it as the convergence of mixed reality (VR Virtual Reality and AR Augmented Reality), video games, online gaming, digital art and graphics imaging that is bringing a new space for developers and creatives. Software developers are building this world using blockchains and decentralized applications on the cloud over the Internet. …

Bitcoin (BTC) has experienced a massive dump on early Sunday morning (April 18, 2021). The crypto king dropped close to $10,000 in price from around $60,000 to a low of $50,900 (Binance). The level of support did hold and not break further to the downside, but no one is out of the woods yet. This also created a domino effect, which is quite expected, with the rest of the cryptocurrency market. The prices of Ethereum (ETH), Binance Coin (BNB), XRP, and other altcoins dropped along with BTC. ETH saw a total of $1.16 Billion in losses, while XRP losses totaled…


Self-Driving Pizza Delivery Robot (Source Motor Authority)

Autonomous delivery robots have been running in trials in some places but they are now expanding. It will no longer be just delivery from the curb, but from store to the curb like what is being implemented in Houston, TX. Domino’s Pizza has teamed up with self-driving car company Nuro to deploy autonomous delivery robots in the Houston area. This comes at a time when delivery service demand is up due to the effects of the COVID-19 virus.

Domino’s Pizza is going down in history with another example of being the first to try emerging technologies. Back in 2016 they…

The much anticipated or awaited upgrade to the Ethereum blockchain is full of optimism. Optimism is an implementation that paves the way to ETH2 using a Layer 2 (off chain) scaling solution called “Optimistic Rollups.” It was supposed to be deployed to the mainnet in March 2021 but has now been delayed until the middle of 2021 (July or later). That announcement could later change since there is just no way to be exact on the date. The Ethereum developers are delaying the launch due to concerns regarding the security and stability of the software.

According to their article on…

The value of digital content can be captured in NFT (Non-Fungible Token), a type of cryptocurrency that is stored on the Ethereum blockchain. This allows anyone to create a token or tokens for their digital content and sell it in an open decentralized marketplace. The NFT industry emerged in 2020, as prices of minted tokens soared based on their demand. NFT include drawings, songs, music, gaming rewards, video clips, tickets, novelty items and just about anything digital or physical that can be tokenized. …

You may have heard from a veteran photographer that editing or retouching an image breaks the rules of photography. Once an image is captured, that is the final result. However, is that fair to those who want to do some post work to enhance their images before sharing or uploading? This may be a divergence in viewpoint between traditional photographers and digital photographers. When I say traditional, I am referring to analog workflows where film is the medium of choice but it can also be digital but involves no post editing. …


Prime Numbers (Photo Credit By Karolina Grabowska)

When we look at prime numbers, they are basically any number > 1 that is not a product of two other numbers. It can only be divided by itself and the number 1. This is the property called primality. Prime numbers occur from 2 to infinity, or as long as there are a sequence of numbers. According to the fundamental theorem of arithmetic, every integer > than 1 either is a prime number itself or can be represented as the product of prime numbers. It also states that factoring numbers can be unique with prime numbers, but not with composite…

Waymo is a self-driving car company, but they don’t particularly like using that terminology. Instead they prefer fully autonomous as a more accurate way to describe driverless or autonomous driving technology. What consumers may not fully understand is the difference between self-driving and fully autonomous. A self-driving car is a type of vehicle that can provide some level of automation like ADAS (Advanced Driver Assistance System) or automatic cruise control. It still requires driver attention for proper operation or it can lead to accidents. A fully autonomous driving mode does not require driver attention and provides full automation without driver…


Web cache poisoning is aimed at vulnerable caching servers to reply with a malicious response back to the requester. It involves two phases:

  1. Elicit a response from a web server to deliver a dangerous payload
  2. Cache the response to target more requesters

In delivering content, cache servers provide faster downloads at the edge of the network. They can also be targeted to launch attacks that can affect the most number of users who are requesting for content. …

If you are to believe that the cryptocurrency market is a bubble, then it is because of an irrational market that is judging a “Keynesian Beauty Contest.” According to investor PlanB, you can separate the players in the crypto space based on their level of thinking. Some play it by ear and base their investment decisions on the market trends (e.g., TA). Others don’t know what they are doing and just FOMO in. Then there are the really rational thinkers who bring smart money to the game. In all this, it appears that the higher an investor’s level of thinking…
