We are excited to announce the launch of the Lumos Metaverse for builders to access the right opportunities and flourish in the Web3 space. To bring this to fruition, we successfully raised $1.1 million in seed capital. The seed round was led by Global Web3 venture fund - , and funding from leading VCs- Superblock, , , , and multiple eminent angel investors from the Web3 ecosystem. Delta Blockchain Fund Next Web Capital Arcanum Capital AG Build Paradigm Shift Capital With a slew of investors consisting of both angel investors and VC firms funding this initiative, the Lumos Metaverse will serve as that proverbial “gateway to Web3”, for builders located both at home and abroad. Why We’re Building a Metaverse A metaverse is a concept where virtual reality is reimagined to create social connections. At Lumos Labs, we believe that a metaverse is the best-suited format that will bring shape and form to our vision. Let’s walk you through our thought process. To propel innovation in the Web3 space, we needed to make sure we’re helping builders (developers) connect with the right opportunities by bridging the proverbial gaps in the ecosystem. Here are those “gaps”: Web3 Builders Are Scarce According to a report from crypto VC firm Electric Capital, there are around 18,000 active builders in the Web3 ecosystem. However, 18,000 is pretty meager compared to the overall web developer market. To put that into perspective, Java — a popular programming language — has 9.6 million builders (SlashData). Given its recent growth trajectory, JavaScript is probably adding 18,000 new builders per week. Case-in-point: Web3 builders are scarce. Opportunities in the Web3 Space Are Fragmented To grow as a developer (or a builder) in the Web3 space, you need to be a self-starter, scouting for the right opportunities to learn, #BUIDL, and focus on building a professional profile. But, there are way too many forums that host opportunities that are not curated in a single reliable place. This includes aggregating opportunities from across several blockchain platform communities’ forums (ex: Polkadot, NEAR, Ethereum, etc.) that can help builders learn, contribute to networks, and grow. Developer/Builder Identities Are Scattered Across the Internet Virtual profiles are immensely popular among builders and serve the purpose of showcasing their skills and talent. However, there are several platforms that aim to provide builders with a space to showcase their profiles. This includes engagement, opportunity and utility platforms like Discord, GitCoin, DevFolio, HackerRank, GitHub, and more. Given how these platforms already have a reputation for showcasing developer profiles, builders lack a place to host a universal proof-of-skill. Lumos Labs comes with formidable expertise in understanding developer needs in the Web3 space. Our journey has led us to conduct 15+ hackathons and 10+ accelerators alongside recruitment programs, providing over $3 million in grants to builders and startups. We are equipped with the knowledge, expertise and support to build this Metaverse. “Metaverses are steadily coming into the mainstream now and we’re, effectively, stepping into a futuristic realm that we mostly saw in science fiction. The Lumos Metaverse will snugly fit into this niche by enhancing collaborative experiences to bring forth a vibrant community of developers entering this space. By building a purpose-driven metaverse as opposed to a general-purpose metaverse, we believe that the Lumos Metaverse will encourage builders to arrive with pre-set goals that they can accomplish. We will host a seamless connect between Web3 platforms and individual builders. Ultimately, we envision the Metaverse to service the Web3 community, bringing in inclusivity by prioritising talent, skill and delivery above all else.” - Kaavya Prasad — Founder, Lumos Labs Get to Know the Metaverse So, What is this Lumos Metaverse, you ask? Simply put, the Lumos Metaverse is a world built for developers, designed to open access to ecosystem opportunities and help them with their journey into Web3. Through this platform, we will guide interested Web3 builders to: Get ahead of the learning curve with workshops, meetups, mentor programs and more Showcase development skills at hackathons and bounties Directly connect with Web3 platforms for jobs, and connect with other builders for collaborations Provide startup support to (aspiring) founders with the right opportunities in the Web3 space to scale up. The Metaverse is open to all builders: students, experienced developers, startup founders, etc., who have the inclination and aptitude to build a career in Web3 as a developer be it for any project enabled by blockchain technology. Visualizing the Metaverse The Metaverse will host a central hub for builders and ecosystem enablers (platforms, VCs, enterprises, communities, DAOs, etc.) to collaborate, showcasing a variety of opportunities to its users. The ecosystem enablers will access Web3 developer talent through the Lumos Metaverse by setting up virtual headquarters (HQ). By means of the HQ, platforms will host various forms of opportunities like developer grants, hackathons, bounties community engagement activities, hiring drives, etc. Most importantly, the Lumos Metaverse will host a holistic platform for a shared community of Web3 builders to solve real-world problems and provide a one-stop-shop for Web3 platforms to seamlessly manage their builder relations. Our Dynamic Initiative With distributed ledger technology and Web3 development enjoying a sharp surge in interest from builders, there’s still a need to gather relevant opportunities, be it to learn Web3, connect with your “tribe”, or even get your first break as a developer. Based on the insights gleaned from Lumos Labs’ Web3 programs, we aspire to cultivate, hone and market developer talent for the Web3 space. As an aggregator of community engagement, educational and job opportunities, Lumos Labs’ Metaverse envisions a thriving Web3 ecosystem. The Metaverse is designed to grow from strength to strength in the future as our clients gain exclusive access to “cream of the crop” development talent. “If Lumos Labs has learned anything from the programmes held to support builders, it’s hard to achieve such a lofty goal with a fragmented approach that, while being decentralised in its own right, serves as a deterrent to passionate and skilled builders from making a mark in the Web3 space. After much deliberation, we strongly feel that Lumos Labs’s Metaverse will provide the much-needed structure, focus and direction that all Web3 builders are in dire need of.” — Kaavya Prasad Furthermore, she thinks that, with blockchain technology and Web3 development still relatively nascent, the Metaverse will not only serve as a springboard for both Indian and international builders to carve out their own niche in the Web3 space but also put India on the map as a major Web3 player. Yes, as a force to be reckoned with, in this fledgling industry that is currently experiencing rapid growth while still failing to meet the demand, in terms of Web3 development talent. In engaging with and nurturing the right talent, the Metaverse can be viewed as a culmination of Lumos Labs’ efforts ever since its inception to make a difference to the blockchain ecosystem — if only by bringing in one Web3 developer at a time. We hope to do the same and so much more with the offerings that the Metaverse hopes to deliver. Make sure you join us on this incredible journey!

On December 7, 2023, ZKFair, the community-driven xZK L2 network, officially announced the launch of its testnet, opening its doors to all community users. https://twitter.com/ZKFCommunity/status/1733050435211280588?embedable=true The project is still in its early stages, allowing users to perform various operations such as cross-chain transactions during the testnet phase. Throughout the testnet period, the project plans to progressively introduce ecosystem projects such as Swap, lending, NFT market, gaming, and collaborate with notable projects like Orbiter, Space ID, OKX Wallet, Bitget Wallet, TP Wallet, Izumi, Meson, unveiling corresponding features. The anticipated mainnet launch is projected around December 20. ZKFair is a community movement focused on addressing pain points within the current ZK L2 ecosystem, including high valuations and barriers to entry for ordinary users. It marks the first L2 network based on Polygon CDK, Celestia DA & Lumoz ZK-RaaS, ensuring a 100% fair launch. On the day of ZKFair testnet launch, over 30,000 users engaged with the community, actively participating in testnet interactions. The innovative economic model has been a focal point of community interest, and this article aims to introduce the innovative 100% community Fair Launch mode initiated by ZKFair. ZKFair utilizes as the gas fee token, and its reward token, ZKF, has a total supply of 10 billion, allocated as follows: USDC 75% for the gas fee airdrop: Users generating transaction fees on the ZKFair mainnet will receive airdrop rewards in ZKF tokens once the gas fee airdrop program is launched (expected 3-5 days after the mainnet launch). The limit is $3 million, first come, first served. 25% for the community airdrop: 8% for Lumoz points holders (viewable on the Lumoz ). website 8% for the Polygon community (specific airdrop method to be determined). 2% for ZKSync, Scroll, ZKSpace, and Linea communities (addresses with interactions in the last 2 months). 2% for early code contributors. 5% for Ordinals community token holders (this airdrop will not be immediately unlocked, waiting until ZKFair supports the BTC ecosystem). *To appreciate the spirit of the Ordinals community, consistently prioritizing community users, aligning well with our vision. Hence, ZKFair is the first project to airdrop a 5% token allocation to the Ordinals community. To ensure absolute fairness in the launch, specific details of the ZKFair gas fee airdrop program will be announced before its launch. The entire process aims for no VC involvement, no pre-mining, and no reservations. After the conclusion of the ZKFair gas fee airdrop program, ZKFair will open ZKF token airdrop claims to all eligible users. Users can claim airdrop rewards through a designated page on the official website within a 10-day window. Tokens unclaimed after this period will be considered forfeited and subsequently destroyed.

This week, a largely unknown company, , demonstrated unprecedented speed running open-source LLMs such as Llama-2 (70 billion parameters) at more than 100 tokens per second, and Mixtral at nearly 500 tokens per second per user on Groq’s Language Processing Unit (LPU). Groq For the : comparison “According to Groq, in similar tests, ChatGPT loads at 40–50 tokens per second, and Bard at 70 tokens per second on typical GPU-based computing systems. Context for 100 tokens per second per user — A user could generate a 4,000-word essay in just over a minute.” So: , and where is Groq (such an unfortunate name, given Musk’s Grok is all over the media) coming from? What is LPU, how does it work Remember that game of Go in 2016 when AlphaGo played against the world champion Lee Sedol and won? Well, about a month before the competition, there was a test game which AlphaGo lost. The researchers from DeepMind ported AlphaGo to the Tensor Processing Unit (TPU), and then the computer program was able to win by a wide margin. The realization that computational power was a bottleneck for AI’s potential led to the inception of Groq and the creation of the LPU. This realization came to who initially began what became the TPU project at Google. He started Groq in 2016. Jonathan Ross Unlike other computer chips that do many things at once (parallel processing), the LPU works on tasks one after the other (sequential processing), which is perfect for understanding and generating language. The LPU is a special kind of computer brain designed to handle language tasks very quickly. Imagine it like a relay race where each runner (chip) passes the baton (data) to the next, making everything run super fast. The LPU is designed to overcome the two LLM bottlenecks: compute density and memory bandwidth. Groq took a novel approach right from the start, before even thinking about the hardware. They made sure the software could guide how the chips talk to each other, ensuring they work together seamlessly like a team in a factory. focusing on software and compiler development This makes the LPU really good at processing language efficiently and at high speed, ideal for AI tasks that involve understanding or creating text. This led to a highly optimized system that not only runs circles around traditional setups in terms of speed but does so with greater cost efficiency and lower energy consumption. This is big news for industries like finance, government, and tech, where quick and accurate data processing is key. Now, don’t go tossing out your GPUs just yet! While the LPU is a beast when it comes to inference, making light work of applying trained models to new data, GPUs still reign supreme in the training arena. The LPU and GPU might become the dynamic duo of AI hardware, each excelling in their respective roles. As Elvis Saravia it: “ ” put With breakthroughs in inference and long context understanding, we are officially entering a new era in LLMs. To better understand architecture, Groq offers two papers: from ( ) and ( ). The term “LPU” must be a recent addition to Groq’s narrative, since it’s never mentioned in the papers. 2020 Think Fast: A Tensor Streaming Processor (TSP) for Accelerating Deep Learning Workloads 2022 A Soware-defined Tensor Streaming Multiprocessor for Large-scale Machine Learning Additional read: Compute is also a part of this paper: , which discusses managing AI development through compute control, focusing on its potential for regulation, benefits, and risks, and suggests balanced governance approaches.

On October 12th, we are thrilled to that Opside has officially upgraded to Lumoz! This marks a significant step forward in Lumoz's development journey. At the same time, we also hope to take this opportunity to enable global users to better understand and apply ZK-Rollup technology, facilitate the large-scale implementation of zkEVM-based application chains, and further drive innovation in ZK technology. announce Lumoz (formerly Opside) officially launched its Testnet at the end of May this year and has been running smoothly for five months with continued strong participation from the global community. As of now, we have accumulated over 240,000 independent users, 25,000+ PoS Validators, and 100+ PoW miners. Additionally, more than 15 projects have passed official review and generated customized zkEVM application chains on Lumoz (formerly Opside) platform. Why Rebranding? Over the past year, Lumoz (formerly Opside) has achieved remarkable success. In the current landscape of RaaS (Rollup as a Service), Lumoz (formerly Opside) is the first and only platform dedicated to ZK-Rollup as a Service, providing underlying computational power. The name Opside originated from "Operator," but as Optimistic Rollup gradually gained more attention, we noticed that an increasing number of users incorrectly classified Opside as part of the Optimistic Rollup field. Furthermore, Opside has made steady progress in 2023, successfully launching the Pre-Alpha testnet, ZK-Rollup Launchbase, ZKP Two-step Algorithm, NCRC protocol, and other important user features. We have also established good communication and collaboration with numerous leading zkEVM projects, modular components, and third-party service providers within the ZK space, covering and involving a significant portion of the vertical direction in this field. In summary, the functionality and offerings provided by Opside can no longer be simply summarized by the term "Operator," and the original name may lead to unnecessary confusion. Therefore, we believe that comprehensive rebranding is necessary. Why Lumoz? After deciding on the rebranding, the team took prompt action and conducted multiple brainstorming sessions internally. We also sought advice from hundreds of community users and industry experts worldwide. As a result, the new name "Lumoz" was chosen. Lumoz is derived from the Latin word "Lumos," meaning "light" or "brightness." It draws inspiration from J.K. Rowling's bestselling novel series "Harry Potter," where "Lumos" is a spell used to illuminate the tip of a magic wand, creating light. By replacing the "s" with "z," "Lumoz" cleverly associates with "zk" (Zero-Knowledge) technology, forming a unique identifier. Additionally, for those familiar with Lumo, it resembles the orbital of a molecule, similar to an L2. We hope that Lumoz can become a beacon of light on the ZK track, illuminating the path for the widespread adoption of ZK-Rollup technology. Lumoz's Vision: Making ZK-Rollup Within Reach Since its inception in 2022, Lumoz (formerly Opside) has been committed to its mission of making ZK-Rollup technology more accessible and user-friendly. To achieve this, Lumoz (formerly Opside) was among the first in the industry to introduce the concept of ZK-RaaS (ZK-Rollup as a Service), catering to the needs of developers to create customized ZK-Rollup (zkEVM application chains) across multiple L1 networks. Over the course of more than a year since Lumoz (formerly Opside) was established, the team has remained persistent in overcoming challenges and achieving significant milestones. In May 2023, with the launch of the Pre-Alpha incentivized testnet, the functionality of one-click deployment of zkEVM application chains underwent successful small-scale testing. In August of the same year, Lumoz (formerly Opside) also made significant updates to the ZK-Rollup Launchbase, adding support for ETH/BSC/Polygon testnets as options for the Rollup L1 main chain and providing various modular components such as DA/shared sequencers. Today, an increasing number of developers/users are utilizing Lumoz (formerly Opside)'s no-code ZK-Rollup Launchbase to create customized zkEVM application chains. Additionally, during operation, Lumoz (formerly Opside) provides underlying computational power for general ZKP computations through the Decentralized Prover Network, allowing project teams to focus on subsequent operations. This significantly lowers the barriers to using ZK technology and reduces operational costs for project teams, while also effectively promoting the widespread adoption of ZK-Rollup technology. Towards the "Light," Lumoz has a bright future With this rebranding, it is evident to the world that Lumoz (formerly Opside) is determined to continue its long-term build in the direction of ZK-RaaS. Looking ahead, we will strictly adhere to the roadmap's plan: Currently, Lumoz (formerly Opside) supports zkEVM types such as Polygon zkEVM and zkSync, with plans to support Scroll, StarkNet, and others in Q4. By continuously expanding support for zkEVM types, Lumoz (formerly Opside) aims to meet the needs of different developers and projects, thereby promoting widespread adoption of ZK-Rollup technology. Supporting more zkEVM types: While the current ZK-Rollup Launchbase already meets the demands of most people, in our plans, these are just the basics. In the future, Lumoz (formerly Opside) plans to provide more modular components (such as integrating more third-party DAs) and functionalities to further simplify and accelerate the deployment of zkEVM application chains. Optimization of ZK-Rollup Launchbase: As of now, Lumoz (formerly Opside) has made significant progress in ecosystem development, with nearly a hundred ecosystem projects covering various domains such as GameFi, DeFi, NFT, Social, and Tool. In the future, we will actively seek opportunities to collaborate with more high-quality projects and strengthen innovative applications at the practical level, while sharing resources and traffic, effectively driving the adoption of ZK-Rollup technology. Continued expansion of ecosystem collaborations: With the gradual maturation of ZK-Rollup technology, there may be hundreds or even thousands of ZK-Rollups in the future, which will create a significant demand for ZKP computing power. Lumoz (formerly Opside) currently incentivizes miners to provide ZKP computing power through the ZK-PoW mechanism, thereby providing complete hardware infrastructure for ZK-Rollup. Therefore, miners will be an important component of the entire ecosystem. To that end, we have been actively adjusting the entry barriers for CPUs and GPUs. The ZKP two-step commitment algorithm proposed by our team has greatly improved the efficiency of ZKP generation. In the future, we will continue to make efforts at both the software and hardware levels to protect the rights and interests of miners to the maximum extent. Developing the miner ecosystem and lowering CPU & GPU entry barriers: While constantly seeking technological breakthroughs, we also aim to make more people aware of and utilize ZK-Rollup, pushing it to the forefront of wider applications. Therefore, in our future plans, Lumoz (formerly Opside) will not only participate in more industry summits/exchanges but also actively disseminate knowledge about ZK-Rollup to developers and users through hackathons, RaaS Days, and other means, providing support and guidance to better assist them in achieving innovation in their respective fields using ZK technology. Facilitating the popularization and promotion of ZK-Rollup technology: In Conclusion The potential of ZK-Rollup technology is unquestionable, and Lumoz (formerly Opside) firmly believes in it. Through this brand upgrade, we not only demonstrate our unwavering determination but also convey our mindset. We wholeheartedly invite all Web3 Builders to join the Lumoz (formerly Opside) network, witness this transformative journey, and become an integral part of the ZK-Rollup revolution. Currently, the Lumoz (formerly Opside) Testnet remains open, welcoming community users, developers, and industry enthusiasts who are interested in participating. By contributing their efforts, they have the opportunity to earn points, which can be exchanged for Lumoz (formerly Opside) Mainnet tokens upon its launch next year.

111 Stories To Learn About Building The Metaverse

Version control systems have had a profound impact on software development ever since their adoption in the 70s. Using version control systems (VCS) in software development has become all but necessary and which is why 70% of software development teams use a VCS like Git for their versioning needs. If that’s not enough, there continues to be a steady increase in adoption in recent years as these systems improve both code management as well as code quality and accuracy. Given how important these benefits are to the much-touted DevOps philosophy, it should come as no surprise that version control systems have become even more important in modern software development. What You Need to Know About DevOps Even if the Software Development Life Cycle (SDLC) has held sway for a while now, there are emerging philosophies that promise to deliver applications and services with shorter turnaround times. One such philosophy is DevOps: a set of practices that go beyond traditional software development with the intent to accelerate a product’s time-to-market and as a result, serve customers efficiently. In particular, there’s a focus on automation and streamlining that should help its practitioners build software faster. When it comes to the application of such a software development methodology, both the development and operations teams collaborate and share responsibility towards the effort of building secure, feature-rich software as quickly as possible. Of course, DevOps teams also tend to examine what real users need and include these features in their quick, incremental updates. On the whole, this antiquated business of teams working in silos is done away with, thanks to the use of a new set of tools that aid in sharing and collaboration. In being able to communicate and share feedback faster with these tools, an accelerated time-to-market of the said software product is achievable, making the DevOps philosophy desirable to adopt. Speaking of DevOps tools, using a version control system (VCS) like Git is probably the most sought-after. Especially since DevOps has begun to play a prominent role in software development. Why Version Control Matters As you already know, a version control system - much like Git - is responsible for managing your code and all the changes that have taken place since the project’s beginning. In other words, a complete history of your code is maintained, avoiding any manual management altogether. When you use such a source code management tool, you will obtain information about the changes made, the timestamp at which the change was made and the person who made such changes. Given how thorough a VCS is in managing all versions of the project source code, there’s no chance of accidental changes. Yet more importantly, teams can work on projects simultaneously while creating branches and merges on the said project to maintain a good ‘mainline’. Concerning the DevOps methodology, a version control system tends to support collaboration and shared feedback through its ability to manage and track files in an automated fashion. Your team gets to see the source code since it is kept in one location for all to access with maximum visibility: all team members can see who is working on what files so that duplication does not take place either.** There are two types of version control systems - distributed and centralized. While the former allows each user to store a copy on their local machine, the latter gives users access to a central server. When it comes to distributed version control tools, most software development teams use Git. Your First Look at Git Authored by Linus Torvalds, Git was first released for use in 2005 to keep track of the development of the Linux kernel. Being open-source software, Git can be downloaded from the website based on the operating system that you have running on your system. Yes, this includes Windows too! Once you’ve installed Git on your system, there are two ways by which you can use this VCS: by using the terminal or a GUI. Several GUIs have been designed to make Git more user-friendly but using the terminal has always been the preferred approach. Speaking of which, the very first command that you must use after installing Git is to check whether it is available on your system or not: In addition, if you want to version control one of your projects, you will have to create and navigate to a project directory by using the following commands: Once you have created a project, it’s time to create a Git repository that will track all source code changes by running the following command: Now, once you have completed this, there are common Git commands that you will use when writing source code in your projects, and which are worth exploring next.** 5 Common Git Commands That Every Developer Must Know As we’ve discussed earlier, most developers use Git as it plays an important role in modern software development. So, if you consider versioning important for your coding projects, here are 5 common Git commands that every developer must get familiar with: Command #1: git config As the name suggests, this command sets configuration options, either in a global sense or for a repo. Two common uses for this command include setting the user name and email address: Command #2: git status As you can see from the output below, the git status command provides you with information about the staging area and working directory. In particular, you get to see the changes made and also the files that Git isn’t yet tracking. Command #3: git add When you run this command, you will add the changes from the working directory to the staging area. What you are doing is telling Git that you intend to make changes to a file when you run the commit command. ** ** Command #4: git commit This commit command will help you to save all changes made to the staged area and is considered to be a ‘safe’ version of the project as the changes made are first added while the commit command ensures that these changes are saved to the local repo. Command #5: git log This command provides the developer with the ability to look at a project’s particular history so that a particular version of the project can be found. Several arguments can be added to refine this search. Now, it wouldn’t be fair not to mention Github since it hosts all Git repositories online so collaboration is made much easier between developers. As a developer, there are three more interesting commands that you can learn and that work with code hosted on Github: git push, git pull and git clone. Like what you’re learning?

Web3 development is here to stay! If the number of smart contracts deployed on the Mainnet is any indication, this spurt in growth since 2021 is only set to continue. Ethereum Speaking of which, this growth in terms of numbers stands at an . If that’s not enough, the Goerli Testnet has seen a substantial increase in the deployment of smart contracts by 721% annually. astonishing 293% between 2021 and 2022 All of this has occurred despite the decline of crypto,  in particular, when the FTX collapse took place. What this translates to is that there’s room for more Web3 developers to hone their skills and add to that growing list of smart contracts deployed. So, let’s dive into how these smart contracts are deployed on the Ethereum Testnet first, using Sepolia. But before that, let’s understand what an Ethereum Testnet is and how one can use it by procuring some Testnet Ether. An Introduction to the Ethereum Testnet As mentioned in an earlier blog post, a public Testnet is an environment in which developers can test their smart contracts with test tokens like Ether or MATIC. This is well before they deploy the smart contract to the Mainnet, so that they can iron out all the kinks in advance. Much like developers in any other Technology domain who test their software prior to deployment in a production environment. Now, this is important to do because once the contract is deployed, no changes can be made. So, if there are any bugs, making changes to the code will not be possible. However, given how closely the Testnet simulates its real-world counterpart, debugging and refactoring your code is possible until you get it absolutely right. Still, no smart contract is 100% bug-free, so while perfection is desirable, it isn’t necessarily attainable. Which brings us to the Ethereum Testnet: one can safely say that there are a few that have come and gone. Ropstein, Kovan and Rinkeby are now deemed deprecated along with Goerli that will operate for a few more months. As of 2023, the Sepolia Testnet is considered to be the right network to use in order to handle application development. But for us to be able to use the Sepolia Testnet, we need test Ether to pay gas fees. One must remember that the Sepolia Testnet has its own test Ether that one must procure from a faucet. For example, a faucet with respect to Testnet Ether is a website where you can request for test Ether, which would be Sepolia test Ether in this case. Steps to Obtain Sepolia Testnet Ether Now, there are several ways to obtain Testnet Ether for Sepolia and which includes visiting designated faucets that will send Sepolia Ether to your account. Assuming that you already have an Ethereum address linked to a wallet like Metamask, the simplest one involves navigating to this that allows you to mine for Sepolia Ether. Once you paste your Ethereum address and complete the “I’m not a robot” reCaptcha, select ‘Start Mining’. As you can see, the longer you mine for Sepolia Ether, the more you can collect. webpage After you’ve gathered enough Sepolia Ether, select the ‘Stop Mining & Claim Rewards’ option. Finally, check your wallet after 10-20 seconds to see if you’ve received Sepolia Ether. If you haven’t, then check your Ethereum wallet details and start all over again. If you have sufficient test Ether, then it’s time to deploy the Donut Vending Machine Solidity Smart Contract to the Sepolia Testnet. Deploying the Donut Vending Machine Solidity Smart Contract Now, in order to understand how smart contract deployment works, we need to use the Remix Integrated Development Environment but use a smart contract whose implementation is easily understandable. For this purpose, we’ve selected the Donut Vending Machine Solidity Smart Contract available at this . Once you copy the smart contract code, add it to a new .sol file in Remix and compile the contract until you see the green tick mark as part of the Solidity Compiler icon. Github link With that out of the way, it’s time to deploy the smart contract using the Sepolia Testnet Ether that you obtained. For this, you select the “Deploy & Run Transactions” icon as shown below: After you’ve completed that step, you should find the Deploy & Run Transactions section Select Injected Provider - Metamask from the drop-menu under Environment and unlock your Metamask wallet with your password Select Deploy and pay the stipulated gas fees by hitting Confirm when your Metamask wallet opens up. Open your deployed smart contract in the Deployed Contracts section Lastly, if you want to purchase 2 donuts for 1 Ether, make sure you update the “Value” section with 1 Ether, add 2 in the Purchase method text box and hit the red ‘Purchase’ button Yet again, you will have to confirm the purchase being made by approving the transaction in your Metamask wallet You should receive confirmation that the purchase went through with the updated contract balance! That said, you can also take a count of the number of donuts by invoking the getBalance function, as shown below: With the initial number of donuts being 100, that number is now reduced to 98 after the purchase went through! Now, it must be mentioned that experienced developers use Hardhat and Truffle but that’s a discussion for another day. How to Use EtherScan to Confirm the Smart Contract’s Deployment on Sepolia With the Donut Vending Machine smart contract allowing customer purchases, you might want to keep track of the transactions being made using your smart contract. A tool that we discussed earlier comes to mind: EtherScan. In order to use EtherScan for Sepolia Testnet transactions, we need to navigate to and paste the address of the smart contract that can be found in the Deployed Contracts section in Remix. https://sepolia.etherscan.io/ At first glance, this is how the Donut Vending Machine smart contract looks on EtherScan If you haven’t noticed, the very first transaction in the list is defined as Contract Creation. Once a purchase is made through the method shown above, the Purchase transaction gets updated on EtherScan That said, the smart contract now has a balance of 1 ETH for the purchase of 2 donuts made too. We’re done! For the next blog post, we’ll demonstrate how customers can interact with your smart contract by building a basic webpage with the necessary UI components. That said, we’re also building - a Web3 education platform dedicated to teaching you blockchain development concepts with comprehensive curriculums.

175 Stories To Learn About Developer

So, what’s one thing that the iOS platform, the Java programming language, and the .NET all offer developers? SDKs, of course. So, this practice of offering a developer toolkit has been around for a while given that each platform in question has its own technologies, processes, and nuances to keep in mind. Clearly, no two platforms are the same, so building applications for such platforms wouldn’t be either. Speaking of which, there are a number of Web3 SDKs available for developers too, even if the technologies involving blockchain development are a long way from being considered mature. But before we broach this topic, let’s get down to basics and learn all that we can about SDKs. SDKs Explained Otherwise known as software development kits, these toolboxes have been built from scratch for developers who wish to build applications for said platform. For the most part, an SDK will contain a compiler, debugger, and necessary APIs but there are other components that might be included namely: libraries, dev-related documentation, IDEs or code editors, testing tools, and necessary code samples that can help budding developers understand the coding tasks necessary to build proper applications. So, instead of building applications from scratch, developers, with a well-designed SDK, can speed up their development process and add much more functionality to their applications than would be possible otherwise. Clearly, the importance of SDKs cannot be overstated here since they really provide developers with a deeper understanding of how the platform works. But in order for SDKs to be effective, there are certain things that must be kept in mind: Should be easy to use and understand by application developers. Offer sufficient functionality that makes it useful in application development. Provides comprehensive documentation on the workings of code. On the other hand, if SDKs have licensing issues, do not support the desired programming languages, offer different permissions in third-party libraries, or worse still, fail to maintain the SDK for all functionality offered, then offering such a toolbox will add no value to the development experience. Speaking of which, let’s address how potentially beneficial it is for organizations to build and offer SDKs to developers next. 3 Benefits of SDKs Just because a developer can write all the code for an application, that doesn’t mean that this is necessary. There are a number of standard tasks that are considered repetitive and boring but can be avoided if developers used the right SDK for the job. Moreover, with the added capabilities that SDKs offer, one can really take their application to the next level. At first glance, these look like important benefits associated with using an SDK. Here are 3 other benefits of using SDKs in development: Rapid Integration & Deployment With most capabilities and code available in the SDK, developers do not have much work apart from integrating the right functionality and making the right modifications for the results that are right for their project. Error-checking capabilities offered by SDKs can help maintain app stability. Without a doubt, an SDK contributes to error-free rapid integration and deployment as a result. Time and Cost Efficiency If developers can do away with repetitive tasks while being able to add new features, thanks to pre-built features that come with SDKs, a good amount of time and money can be saved. Developers can focus more on fine-tuning the application rather than testing and refactoring the code. On the whole, the faster the application is built, the sooner it can be released for use by the public and which makes a positive impact on ROI. Control & Customization SDKs give developers adequate control and customization over what they’re building. Especially when it comes to staying in control of elements in the application that interact with other programs. Whether this pertains to the look and feel of the application or its functionality, an SDK can help developers make necessary changes in a way like no one else can. It’s the developer who retains control over the application and no one else. Now, keeping these benefits in mind, the Lumos Metaverse has begun to work on SDKs for this purpose, since it not only offers these benefits but also solves long-standing problems that have plagued budding Web3 developers for a while. The Multi-Wallet Login Widget SDK - At First Glance One of the most common problems that Web3 developers face when building dApps for Lumos-sponsored hackathons: offering the multi-login wallet capability. In other words, providing users with wallets other than Metamask with the ability to use their apps. In fact, with no pre-built code available to offer this capability, most Web3 developers have to code in this component right from scratch. This takes away coding time and efforts that should be ideally devoted to building unique features related to their dApp. So, building this multi-wallet login SDK was a no-brainer, as developers can easily plug and play this standard component with their dApp! As for its obvious benefits, users who use dApps that use this standard component will be able to log in with both Coinbase and Metamask wallets. In future iterations of this SDK, more wallet options will be added for user authentication. What should also be obvious is that Lumos Metaverse intends to offer the benefits discussed in the previous section about SDKs in general. How to Add the Multi-Wallet Login Widget to Your dApp Now, if you want to add this multi-wallet login widget to your dApp, you can run the following command in the terminal or command line: Now, proceed to add the code below in your React app, as shown below: . You can find the SDK code at this GitHub link So, what does this code do? Upon running the code, we obtain the following button: Once we select the button, we get two wallet authentication options, as shown below: Voila! We’re done! You can continue to work on your dApp without worrying about user authentication. Now, if you’d like to report a bug, suggest other wallets for addition, or would like to just share your thoughts, connect with us at the .

Even though the notion of a smart contract dates back to the 90s, Ethereum was the first platform to realize its potential and eliminate the need for a third-party by virtue of its implementation. With Ethereum taking center stage, the smart contract market has grown from strength to strength and is estimated to grow to a market size worth . Obviously, with smart contracts finding favor in projects across several industries, it should come as no surprise that smart contract developers get paid well, given this increase in demand. US$ 8.3 billion by 2030 Speaking of which, this week’s blog post introduces the topic of smart contracts but in a language that most web developers might find easy to transition to: we're talking about Solidity. The Remix Integrated Development Environment If you want to learn smart contract development, the ideal choice involves selecting a language that is popular, simple to learn and offers an easily accessible development environment. For this reason, most smart contract developers begin with Solidity and for which, the Remix Integrated Development Environment is the first tool that they generally begin their journey with. For most, this will be the first time they use a development environment but this is made effortless since the Remix IDE can be set up in any of the popular browsers. web3 development At a basic level, it’s important to note that each smart contract is a .sol file by virtue of the language that it is written in: Solidity. Also, compiling the contract requires you to select which version you wish to use. Both these tasks of writing and compiling your smart contract must be performed prior to deploying your smart contract to a Testnet or a Mainnet. Speaking of which, it is vital that you test your smart contract on a Testnet prior to deploying it on the Mainnet. When using Remix, you can use either the Goerli or Sepolia testnet. However, for this, you will need to connect your Web3 wallet to Remix in the first place - preferably, using the Metamask wallet. If you have no idea what a Testnet is, think of it as an environment where you get to run your contract using fake funds while evaluating whether your smart contract is ready for the real world through testing. In short, it’s a simulation of how the smart contract will work prior to its deployment on the Mainnet. Lastly, you need to understand that every smart contract, once deployed, is identified by a unique address. Of course, you can move funds in and out of your smart contract by means of dummy user accounts that are available in Remix. Also, you must also learn everything you can about paying gas fees and how it gets deducted from your account as you write out and run your first smart contract too. Your First Steps to Using the Remix IDE Now, if you want to write and compile your first smart contract using the Remix IDE, there are four icons in the icon panel that you must learn to use: Each of these four icons represent different functions on how to use the workspace: File Explorer Search in Files Solidity Compiler Deploy & Run Transactions Selecting File Explorer takes you to the default workspace, as shown below: You should be able to create, modify and delete folders and Solidity files here. Uploading files to your workspace as well as adding it to a Github gist are options that are available too. The second icon in the panel is labeled Search in Files, and which allows you to do just that. In this case, we’re looking for the search term ‘vending machine’, and for which, the results appear below. As for selecting the Solidity compiler option, we are taken to a screen, as shown below: Here you can select the compiler version and the contract you want to compile before hitting the blue button, as shown above. As for the final icon in the panel namely Deploy & Run Transactions, we will cover how to use that icon in the next blog post of this series. Working With Your First Solidity Contract Now, a number of popular smart contract languages have their syntax similar to JavaScript, Python and Rust - languages that are already popular among experienced developers. Yet the one that stands out is Solidity as the Ethereum platform continues to hire developers at an even clip, so it is best to begin our journey with an implementation of a vending machine smart contract using this language. You can copy the vending machine smart contract code from this . Ethereum webpage It must be pointed out that the working of a vending machine is very similar to how smart contracts function. In fact, the two methods ‘refill’ and ‘purchase’, as you can see in the Vending Machine smart contract, replicate the actions that the owner of a vending machine and its buyers perform in real life. Now, navigate to your workspace by selecting the ‘File Explorer’ icon. Open a new .sol file using the Create New File icon, as shown below: Now, paste the Vending Machine smart contract code into that file along with the SPDX-License-Identifier, as shown below: After this, it’s time to compile your first smart contract in Remix based on the compiler version selected in the “pragma” statement. Of course, debugging for errors will be a part of this process too. Compiling Your First Solidity Smart Contract in Remix Now, once we’ve added our smart contract code to a .sol file in our default workspace, the next step is to debug your code. As a result of zero errors, you will compile the smart contract prior to deploying it to the Testnet. Before we begin, the Ctrl + S keyboard shortcut will compile your smart contract. Now, if the Solidity Compiler option in the icon panel has a green check mark, your code is ready for deployment! Of course, not everything goes to plan. In most cases, there will be errors that you will have to sort out prior to succeeding with your attempt to compile the code you have written. The Solidity Compiler icon will look something like this, where ‘1’ indicates the number of errors in your code: Speaking of common errors, beginners tend to fail to select the right compiler version that matches the one chosen in the smart contract’s pragma statement, as shown below: In order to fix this, access the drop-down menu in the Solidity Compiler option: Change the compiler version to “0.8.7+commit.e28d00a7”, to obtain the following result: Another common error involves making syntax errors, such as the one involving the “cupcakeBalances” mapping: If you haven’t noticed already, the red exclamation point enclosed in a red box indicates the statement that has an error. In this case, once you correct the typo by adding a “k” and hit Ctrl + S, that sign disappears. With a resolution of these two simple errors, you’ll also find a green tick mark appearing with the Solidity Compiler icon. Clearly, you’ve successfully compiled your first smart contract. So now, it’s time to deploy your smart contract to the Testnet but this will be covered in a future blog post. That said, we’re building a developer-centric Metaverse for you to learn more about Web3 Development and build your skills.

If there’s a statistic that sheds light on the impact and importance of JavaScript in web development, it’s that . 98.3% of all websites employ it as a client-side programming language With such a high rate of adoption, JavaScript as a programming language is here to stay. This should be clear enough. In fact, we can safely conclude that for this reason, to meet such demand. 72% of all organizations look for JavaScript developers But what does JavaScript do? Before we decipher this, let’s distinguish between static and dynamic web pages, that has led to the rise of JavaScript in the first place. Static vs. Dynamic Web Pages We live in the age of the ‘social Web’, where user-generated content and interactivity holds sway. Unlike Web1, which involved reading static pages of content but didn’t allow much interaction, Web2 provides output based on specific user input. For example, look at the default web page for the Fedora distribution. Is any interactivity possible? Clearly not. It contains mostly read-only information that will be the same, no matter who accesses this page. In fact, no matter how many times you load , you’ll find that the image and the content remains the same on the page. https://getfedora.org/en/ In stark contrast, a dynamic web page generates unique content for every user, with YouTube being an excellent example in this respect. As you might already know, YouTube remembers all your prior searches and the videos that you viewed. Based on this, every YouTube user finds a personalized set of recommended videos as soon as this web application is opened for use. Simply put, whenever a user loads the hyperlink , they see a whole list of videos in the common YouTube layout that has been curated specifically for their needs. https://www.youtube.com/ Now, if you can spot the difference between the two, this is due to the difference that JavaScript makes, as it is responsible for modifying web page behavior in conjunction with HTML and CSS. JavaScript: The Third Building Block of the World Wide Web As mentioned in the previous blog post, there are three building blocks that make up the World Wide Web, where HTML and CSS make up the first two. JavaScript, known to control the behavior of web pages and handle user interactivity, is the third technology that completes this trio that has been used to build the World Wide Web. Since this language is used for mobile and web applications as well as game development, it has become very popular and which can be evidenced by a thriving developer community and several thousands APIs available for use. When it comes to the characteristics of a programming language, JavaScript is a dynamically and weakly typed language that can be added in a HTML document between the <script> insert js code here <script/> tags. Of course, you can add the JS code directly between these tags. Or even put your code in a .js file and add that filename between the script tags too. Let’s look at a simple example of JavaScript functionality that is interactive in nature: If you add this code to a html file and view it in any browser, you should find that a button labeled “Click here” is displayed, as shown below: Upon doing so, an alert box that reads “Success” loads after 2 seconds. Here’s the output: As simple as this example is, you wouldn’t be able to do such things using only HTML and CSS since these two technologies help with building static pages. This is exactly how JavaScript makes a difference. Now, if you’re interested in learning more about JavaScript, what basic topics do you cover, in terms of syntax? Let’s find out, shall we? Learning JavaScript: 7 Core Concepts to Consider Before we begin, while JavaScript and Java might not seem different, both these languages are and have been designed for very different purposes. Please do not confuse between the two. Now, for this section, we look at 7 core concepts of JavaScript that beginners should learn: #1: Variables & Data Types Since variables are the simplest way to hold and change state, let’s begin with how to declare and initialize variables in JavaScript. Both the ‘let’ and ‘var’ keywords help you with this, as shown below: Upon obtaining the output in the console, we should get 4. Of course, the variable x and y can hold strings and floating point numbers along with integers. Other data types include BigInts, boolean, null and objects too. #2: Control Flow There are four types of control flow namely selection, iteration, procedural abstraction and recursion. Among the four, selection is the simplest and which is implemented using an if-else statement, as shown below: As you can tell, the output of this JavaScript code snippet will be the statement enclosed in the “if” statement, as shown below: You can learn more about iteration, procedure abstraction and recursion by examining for and while loops, function calls and recursive functions in JavaScript. #3: Functions By definition, a function is written so that it performs one task and is reusable by making simple function calls, much like the last statement in the code snippet below: As you can see, the console output displays the following message: You can call this function as many times as you want, if you want that message displayed. This would not be possible if the code for this task wasn’t enclosed within a function. #4: Arrays Data structures such as arrays come in handy when you have several variables to declare and initialize. Let’s say you had to search for a particular name from 250 university graduate students. So, instead of using 250 variables for all names, you could add all names to an array that serves much like a list, as shown below: You can access each of the names using indices but that’s a discussion for another day. #5: Objects If variables contain a single data point, arrays can hold several. On the other hand, objects can hold a set of data points that have a semantic relation with each other. As shown below, the student object contains data belonging to both student name and course that make sense in the real world. In other programming languages, we refer to a JavaScript object as a hashmap or dictionary, where this data structure consists of a key-value pair. #6: Error Handling No matter how good you are as a programmer, making mistakes is part and parcel of development. This holds true for code in JavaScript just as it is in other languages too. So, in order to deal with such instances, using a try-catch block of code should do the trick. Without the try-catch error handling construct, we would not be able to locate this Reference Error, which occurs when an incorrect reference to y has taken place. #7: Asynchronous Programming By definition, asynchronous programming involves the concurrent execution of functions rather than in the sequential manner in which code is executed. As you can see from the output below, the second console.log command is executed while the setTimeout function is running. After this, we get the output from the displayTimeOutMsg function. What we can gather from such an example is that while the displayTimeOutMsg function is running, the second console.log command is also executed in parallel. If execution was sequential, then the displayTimeOutMsg output would have appeared before the output of the second console.log command. A Closer Look at Manipulating the DOM Among the three technologies used to build webpages, only JavaScript is considered to be an authentic programming language. Of course, the reason why JavaScript was included is because of the advent of dynamic web pages that encouraged animation and interactivity. As you might already know, this is done by manipulating the Document Object Model (DOM). So, what is the DOM, you might ask? Think of it as a programming interface for HTML and XML that can be used by developers to create entire documents, add, modify or remove elements and content as well as navigate this tree-like structure. Speaking of which, how do we use JavaScript to perform DOM manipulation? Here are two examples: Get HTML text from DOM The HTML element in question is: Result: Add new HTML element In this case, the HTML element, with three list items, include: Result: As you can see, a fourth list item has been added above. You can also use JavaScript for event-handling tasks, where one such task involves calling a function when the focus for an input field is set: Here’s the HTML element in question: Result: Now, jQuery in particular, was designed to offer DOM manipulation functionality, event handling, built-in animation effects, AJAX interactions apart from supporting basic XPATH syntax and CSS3 selectors. For that matter, it simplifies how developers can perform such actions by reducing the amount of code that is written for said action. That said, you can use certain JavaScript frameworks for both frontend and backend development too. A Note on Frontend JavaScript Frameworks Nothing in front-end development would be the same without the JavaScript frameworks that remain popular among developers. Some of these options include React, Vue and Angular while others such as Svelte and Ember are used. Not only is it faster to build UI elements using pre-written templates and scripts but they are easier to edit, test and update. With reliable code structure and a massive number of features available to developers on these frameworks, starting a web development project from scratch is a thing of the past. How will learning JavaScript help with Web3 development? 📌 Even if web2 and web3 development differ in many aspects, there’s one where the tools and frameworks used are almost the same. We’re talking about front-end development that deals with web page user interfaces. In other words, what the user sees and works with. Speaking of which, learning how to use HTML and CSS in conjunction with JavaScript should make these pages dynamic and interactive. In other words, making the user experience just as rich and engaging in web3 as it has been in web2 for years now. That said, we’re building a developer-centric metaverse for you to learn, earn and get hired.

Therefore, it is important to mention which spells manage to stand out as the best ones in the game. Here are the five best spells in Hogwarts Legacy: - This is the main damage spell that players will use throughout the game. It has solid damage, a bigger range than Incendio, and can be upgraded to hit multiple enemies. Confringo - One of the best combo spells in the game. Paired with Confringo or Diffindo, this can deal phenomenal damage and even one-shot some enemies. Glacius - The strongest spell in the game by far since it can kill any enemy. However, it has an exceptionally large cooldown, which makes players think twice before using it on any enemy. Avada Kedavra - A mind control spell that offers amazing utility by allowing the player to have an enemy fight on their side. Additionally, the mind-controlled enemy will have increased survivability to ensure it doesn’t die easily. Imperio - Flipendo stands out due to its phenomenally short cooldown. It’s a great way to get enemies airborne constantly without worrying about cooldowns. Additionally, it’s a great way to set up combos with almost every other spell. Flipendo Keep in mind that based on your playstyle, you’ll have to switch the equipped spells constantly. If you’re more focused on doing puzzles, you’ll almost never unequip Accio or Levioso. Instead, if you’re more focused on combat, you can even fill your slots only with damage spells. Additionally, spells on their own don’t help much. Instead, the best way to take down enemies is by utilizing spell combos.

There are a dozen things to get distracted with. Sadly, for every second we get distracted when we should be working, our productivity decreases. The worse part is, there are clusters of these seconds which end up ruining our productivity terribly. Truth is we cannot get rid of these distractions completely, however, what we can do is to minimize these distractions to a point where it becomes negligible. By reducing the distractions we automatically increase productivity. However, distractions are not the only factor affecting productivity. There are many factors that affect productivity and regulation of all of those can help us increase our productivity. Factors that affect productivity While several reasons can play a part in workplace productivity in an organization, what we will be talking about are the factors that we can regulate on our own. There are a lot of aspects that we can take care of in order to increase our productivity. A healthy person can reach places. A sick person naturally takes more time for any work. Therefore, it is extremely necessary for us to take care of our health. Physical Health: To be great at what we do, our minds need to be in perfect shape. Suffering from any disorder even if it is mild, can mess with the output we expect from ourselves. Mental Health: : Most of us overwork ourselves without giving the body and mind the rest it deserves. Some people wonder if sleep can actually improve productivity. Truth is, it does, in ways, we can’t even imagine. Sleep Can sleep improve our productivity? Right amount of time needs to be given to the right work. In reality, time management and priority management go hand-in-hand. Time Management: 15 apps that make you productive How wonderful would it be if we had the correct selection of apps on our phones that could increase our productivity by folds? Here, 15 amazing apps have been listed for increasing our productivity. It has been known that writing down stuff before ending the day is a great pathway for the next day to go smoothly. When we have our to-do list prepared for the next day, it helps us be better at our job. Five Minute Journal: It is an app that keeps every event in check. It will keep us updated about what is supposed to be done at what time. Remindo: This app helps us track our time and also see where we spent our time. It aims at making us work harder and better. Productivity Challenge Timer: This is another app that aims at managing the day properly. Day management plays an important role in how productive we are at the end. Todoist is a great app to achieve that. I've been using Todoist since last year and I would recommend it all along. Todoist: : Headspace works on our, well, headspace. It is an app that helps us meditate and keep ourselves calm and peaceful. Meditation is a great tool for maintaining mental decorum. I was a big fan of Calm as a meditation app. But since I moved to Headspace, I've not looked back. Here's how 10 minutes of meditation per day changed my life. :) Headspace Sleep Cycle is an app that is an alarm clock, but smarter. It tracks the sleep cycle and gives us a report of our sleep quality. Sleep Cycle: Lumosity is an app that works on various mental ability aspects. It has various activities to help our mind react better to things. It had various training for different individuals. Lumosity: It is an app that keeps us away from the distractions of phones. Everyone has to agree that the phone is one of the biggest distractions at work. It starts building a forest. We can set a timer and a tree starts building. Using any other app will kill the tree and the fear of losing progress is what keeps us focused. It is a creative app to help us stay focused. Forest: Flipboard is an app that collects news and happenings from all the social media and presents it to us in one place. Many of us have the habit of going through multiple social media sites the first thing in the morning, but we end up wasting too much time separately on all of them. This app helps us by bringing all of it to one place. Flipboard: This app saves whatever goals we have planned for ourselves and keeps us reminding about the same until we achieve it. As we make progress towards the goal, we receive reward points. It is a great app to track any new activity. Coach.me: This app keeps a track of how much time has actually been spent working and how much has been wasted. This works as a great motivation and realization to use the time appropriately. ATracker: The app keeps a track of everything. It has a to-do list for managing all our tasks and a calendar for a detailed description of the same. It also tracks our productivity and reminds us of anything important. Productivity Tracker: To-do list, analytics: - Stay Focused & Control Your Time: This app aims at keeping us focused when it is required. It blocks sites and apps which tend to distract us and helps us in increasing our self-focus. BlockSite This app promotes self-improvement. It has a self-improvement program, keeps our productivity in check, has a number of brain games to help our minds work better, and so much more. Good App, Self Improvement & Personal Growth app: This app comes with a set of sounds that help us relax our minds and get rid of mental exhaustion. An exhausted mind never works to its full capacity. It can also help promote good sleep. Monk Mode - Work like a Zen!: Conclusion There is not a single thing that affects productivity. These apps cover the major factors and try to work on them, in order to make ourselves go through a disciplined day that is bound to increase our productivity. Some apps work on our schedules, while some work on making our minds more active. A few of them track our day while some give us activities to do. We can choose the apps to help us in whatever area we lack in.
