Did You Know: Kubernetes Optimizes Audio-Streaming on Spotify! Spotify is an audio-streaming platform that was created with a vision to empower audio creators and endow listeners across the globe with a really immersive listening experience for all the customers across the globe. A customer-centric approach and a vision to empower creators have led to the exponential growth of the platform which has now grown to a superfluous number of 200 million monthly active users. Spotify, quite early, recognized the importance of containers and deploying microservices in a cloud-native environment. Consequently, they adopted a containerized environment pretty early and were amongst the few companies to even develop a home-grown platform for orchestrating the containers, which was named Helios. Adopting Kubernetes Meant Embracing Limitless Possibilities for Spotify Having adopted microservices and Docker quite early, Helios was a need-based innovation for managing the containerized environment for the Spotify team. However, the Spotify team soon realized the need to outgrow from this homegrown orchestration to Kubernetes. Helios only had limited features that could only be maintained by a small company at Spotify, contrary to this Kubernetes has many more functionalities that make it much more efficient than Helios and hence an obvious choice. Besides being laden with innumerable features Kubernetes also has an amazing community. To Spotify adopting Kubernetes was akin to adopting an orchestration tool that was not only already popular among many industry verticals but also could help their team get containers orchestrated more effectively, efficiently, and faster, and all of this, at a much lower cost than what the company had to incur with Helios. Also, there was a seamless migration from Helios to Kubernetes as Kubernetes could very effectively be used in conjunction with Helios, supporting migration until the platform became the only option for the full-fledged maintenance of the Spotify containers. Positive Impact of Adopting Kubernetes Migrating to Kubernetes required developing some core technological competencies. However, once the technological challenges were addressed and dealt with in 2019, and the company migrated to Kubernetes from their homegrown platform Helios, they experienced some amazing benefits in real-time business scenarios including the following: a)      The internal teams were able to considerably reduce the time spent on manual provisioning which meant that more time could be given to delivering features for Spotify. b)      The team was able to deploy some of its biggest services on Kubernetes, the likes that could handle as many as 10 million requests per second and cumulatively; the feature of Kubernetes proved simply amazing for the team. autoscaling Prior to adopting Kubernetes, deploying a new service for the team wasn’t this hassle-free. They had to at least wait for an hour to create a new service and would have to get an operational host for running the service in production. However, with Kubernetes the story was different. The same services could be deployed in seconds and minutes. c)       Kubernetes also helped improve the CPU utilization by 2 to 3 times approximately as it has the functionalities called bin-packing and multi-tenancy. d)      Kubernetes helped the autonomous engineering teams at Spotify work at a faster velocity and iterate more quickly even while working on different pieces of a project. Before switching to Kubernetes, Spotify since the year 2014 had been using microservices and Docker. The microservices were running across its fleet of Virtual Machines (VMs) and were containerized by leveraging Docker. The company used to manage and keep the data on-premises with the help of their home-grown container orchestration platform Helios before they migrated all the on-premise data to Google Cloud in the year 2016-17. Eventually, switching to Kubernetes proved to be a beneficial decision that offered innumerable advantages including accentuating the time of delivery of several services, leading to optimum business revenue. A substantial motive for the Spotify team to adopt Kubernetes was that the team wanted to contribute their subject-matter-expertise and influence to make the Kubernetes community prosper. Final Words: Takeaways From Spotify Use Case & the Road Ahead For Kubernetes With Kubernetes, not only the Spotify team was able to scale their topline operational metrics viz. lead time, deployment frequency, time to resolution, and operational load but were also able to get all the help to deploy the technology. The Kubernetes team was proactive in providing support and almost everybody was available to help the Spotify team with the technical know-how and expertise required while deploying a particular service. This served as a source of resurrection and motivation for the Spotify team to further scale-up their operational efficiency. The Spotify team leveraged several Kubernetes APIs and other extendable functionalities to aid and interface with their legacy infrastructure. The integrations were hassle-free and easy for the Spotify team. Because of saving so much time with Kubernetes, the Spotify team was able to experiment with solutions such as gRPC and Envoy. Kubernetes is becoming a go-to solution for companies with large development teams and complex IT needs. That's because software developers can use Kubernetes to automate the process of building and managing complex IT infrastructure. Kubernetes is already seeing adoption across many different industries and it will continue to grow as more governments and organizations come around to the benefits of its agility and automated operations. There are several other use cases that narrate the success story of Kubernetes across all industry verticals including media, publishing, audio streaming, and podcasting. These stories demonstrate the amazing possibilities that unfold when a team has the right API and enough time.

Table of Links Abstract & Introduction Observation Data Reduction and Processing Model Spectra Cross-Correlation Method Results Clouds and Hazes Implications for JWST Conclusion and Acknowledgement Appendix & References 4. MODEL SPECTRA We searched for chemical species in GJ 486b’s atmosphere through a cross-correlation analysis with model transmission spectra. We generated a grid of template spectra using the open-source radiative transfer code petitRADTRANS[5] (Molli`ere et al. 2019). Each template contains one or more absorbing chemical species embedded in a background of spectrally inactive gas. Specifically, we searched for a wide range of gaseous absorbers: C2H2, CH4, CO, CO2, FeH, H2O, HCN, H2S, K, Na, NH3, PH3, SiO, TiO, and VO. We used the default opacity data included with petitRADTRANS (see Molli`ere et al. 2019) for all species. However, for CH4 we used both the default opacity data from Exomol (Yurchenko & Tennyson 2014) and our custom-made opacity grid based on a line list adopted from HITEMP 2020 (Hargreaves et al. 2020). We produced the custom opacity grid following the pressure-temperature grid in the petitRADTRANS website (e.g., PTgrid.dat). We calculated the cross section using HELIOS-K 2.0 (Grimm & Heng 2015; Grimm et al. 2021) with a line wing cutoff of 100 cm−1 at a resolution of 0.001 cm−1 which was later resampled at a constant resolution of R = 106 . Our templates include two chemical models: (i) single chemical species models and (ii) multispecies chemical equilibrium models. Our single-species models span a range of volume mixing ratios (VMRs) and MMWs. The VMRs range from log10(VMR) = −7 to 0 (assumed constant with altitude). We varied the MMWs independently of the VMRs, subject to the following boundary conditions: (i) the minimum MMW corresponds to a H2-dominated atmosphere with the template species (i.e. MMWmin ≈ 2 · (1 − VMRi) + VMRi · MMWi); and (ii) the maximum MMW corresponds to an N2-dominated atmosphere with the template species (i.e. MMWmax ≈ 28 · (1 − VMRi) + VMRi · MMWi). These boundary conditions ensure the MMWs are physically consistent with the presence of a spectrally inactive gas mixture with unknown ratios of H2, He, or N2. These models assumed an isothermal pressure-temperature (P-T) profile at GJ 486b’s equilibrium temperature: 700 K (Trifonov et al. 2021). Our second set of models included all the above mentioned spectrally active species with thermochemical equilibrium abundances. We computed equilibrium abundances for a solar composition atmosphere using the open-source code GGchem[6] (Woitke et al. 2018), assuming isothermal P-T profiles at 400, 500, 600, and 700 K. We considered three different approaches for modeling condensation in GGchem: (1) no condensation, (2) condensation included, and (3) condensation included, but condensates removed (e.g., rain out). These abundance profiles are shown in Fig. 1. Although condensation would likely result in the production of aerosols such as clouds or hazes, we do not attempt to account for the effect of such aerosols on the resulting transmission spectrum. Our petitRADTRANS models were computed line by line at R = 106 using 130 layers spaced evenly in logpressure from 10−11 to 102 bar. We then resampled the model spectra to the resolution of the data (R = 45 k, 70 k, and 75 k for IGRINS, IRD, and SPIRou, respectively) using the SpectRes package[7] (Carnall 2017) which preserves the integrated flux. Because cross-correlations are not sensitive to continua, we subtracted the continuum from our model spectra (after binning to the data resolution) to produce our final cross-correlation templates.

High-Resolution Transmission Spectroscopy of the Terrestrial Exoplanet GJ 486b: Model Spectra

Welcome to an exclusive conversation with Trung Trang Nguyen, the visionary architect of U2U Network. In a world where blockchain technology is rapidly evolving, Nguyen stands at the forefront of innovation, offering unique solutions to some of the most pressing challenges in the industry. Today, he joins us to delve deep into the inner workings of the U2U Network, revealing how they are redefining scalability and setting new benchmarks for the future of decentralized technology. Get ready to uncover the secrets behind U2U Network's revolutionary approach and its impact on the blockchain universe. Breaking New Ground in Blockchain: Trung Trang Nguyen Unveils U2U Network's Visionary Approach Thank you for joining us, Trung. As the architect behind U2U Network's innovative solutions, could you explain how the U2U Network uniquely addresses the issue of scalability in blockchain technology? Ishan Pandey: First of all, I want to say thank you for your interview invitation, I appreciate this opportunity to share about U2U Network. Trung Trang Nguyen: About your question, I can definitely confirm that scalability is currently a massive pain point for blockchain technology - one that many have been trying to overcome over the past few years. Even though much progress has been made, most technologies have not reached a high enough level of throughput for mass adoption, all while bearing trade-offs of either security or decentralization or both - which is never a good thing. U2U Network uniquely addresses the scalability problem with the modular tech stack using U2U Subnet. Empowered by our two disruptive technologies which are Universal Message Verification (UMV) and OstracismVM, U2U Subnet is able to facilitate infinite scalability while still maintaining security and consistency. With U2U Subnet, I am confident that the scalability issue can now finally be addressed. With the emergence of Web3, how does U2U Network's infrastructure support the evolving needs of decentralized applications and services? Ishan Pandey: I agree with you that Web3 has risen strongly in recent times, signifying a transformative shift towards a decentralized digital ecosystem and revolutionizing how applications and services operate. This new paradigm prioritizes user sovereignty, data privacy, and peer-to-peer interactions. (dApps) are at the forefront, requiring robust, transparent, and resilient infrastructures to function effectively. This, again, highlights the necessity for innovative infrastructure solutions that can adapt to the dynamic and decentralized nature of Web3. Trung Trang Nguyen: Decentralized applications The search for such solutions now requires an out-of-the-box perspective. A top-tier VC firm - a16z, recently stated on their report about how the modular tech stack is becoming a spotlight in 2024. They said, “Monolithic architectures have the advantage of allowing deep integration and optimization across what would otherwise be modular boundaries, leading to greater performance… at least at first. But the biggest advantage of an open-source, modular tech stack is that it unlocks permissionless innovation; allows participants to specialize; and incentivizes more competition.” U2U Network is one of the earliest to realize this philosophy and directly apply the modular technology at a protocol level. The remarkable performance of U2U Network is largely attributable to our modular approach. This modular design philosophy not only enhances performance but also ensures adaptability, making the U2U Network well-suited to the evolving demands of the Web3 landscape. Helios Consensus, empowered by U2U Chain and U2U Subnet, provides up to 500,000 TPS and 650 ms transaction finality time, which is more than enough for any decentralized application and service of any scale. The U2U Network offers various services like DeFi, NFT, GameFi, and more. How do you ensure a balance between the diversity of applications and the overall performance of the network? Ishan Pandey: U2U Network can easily maintain network performance even with a massive number of applications thanks to its modular tech stack. As you may already know, U2U Network is made up of 2 core components: U2U Chain and U2U Subnet. While U2U Chain is made for robust dApp development, U2U Subnet is designed specifically for decentralized services like Decentralized Private Network (DPN), Decentralized ID (DID). Trung Trang Nguyen: The unique characteristic of U2U Network is that both U2U Chain and U2U Subnet can process transactions in parallel. For U2U Chain, this is enabled by the Directed Acyclic Graph (DAG) structure which differentiates U2U Chain from other conventional blockchains. For U2U Subnet, each Subnet is created optimally for only one task, allowing all Subnets to handle transactions in parallel without affecting each other. Thanks to U2U Network’s capability of parallel processing and its modular tech stack design, there is never a worry of network bottlenecks. Regarding business strategy, how does U2U Network plan to attract and retain developers and users in the highly competitive blockchain space? Ishan Pandey: : On the user side, along with the normal Web3 users that are directly involved in our ecosystem, U2U Network also serves a very special and important type of customer, which are Web2 businesses. With our Decentralization on Demand (DoD) service, we expect to help a lot of these businesses on-board their applications and systems onto the blockchain at ease. This allows us to access a very enormous user base, one that most have not paid attention to in this competitive blockchain space. Trung Trang Nguyen On the developer side, U2U Network finds it really crucial to attract developers and builders of decentralized products and applications, especially when the human resources in this space are still incredibly scarce. To address this, we are constantly organizing hackathons with great rewards for participants and winners, ensuring that more developers acknowledge about and participate in the U2U Network. At the same time, we have introduced various grant policies for developers intending to financially support them with building on our ecosystem, so they can focus on delivering the best products. What vision does U2U Network hold for the future of blockchain technology, particularly in real-world applications? Ishan Pandey: We envision a future where blockchain technology is seamlessly integrated into daily applications, enhancing efficiency, security, and user experience. We aim to be the catalyst in this transformation, enabling real-world applications to harness the full potential of blockchain technology without the complexities often associated with it. From our point of view, this is best done with the modular tech stack. Considering the nature of real-world applications which require an extremely high frequency of transactions, we believe that the modular tech stack is our most optimal solution for this demand. That is why we are committed to developing our modular technology in the next few years, aligned with our vision to onboard more real-world applications onto the blockchain. Trung Trang Nguyen: The U2U Chain boasts an impressive transaction finality speed of 650ms. Can you delve into the technological innovations that make this possible? Ishan Pandey: As mentioned earlier, U2U Network’s outstanding performance is a result of our modular tech stack, which is empowered by U2U Chain and U2U Subnet. Trung Trang Nguyen: U2U Chain is a DAG-based, EVM-compatible chain. Its uniqueness is threefold: First of all, U2U Chain uses DAG as the core data structure rather than the traditional blockchain technology, enabling incredibly low latency and faster transaction finality time. Second, U2U Chain can achieve aBFT (Asynchronous Byzantine Fault Tolerance), the most secure consensus mechanism known today. Third, U2U Chain utilized DPoS (Delegated Proof of Stake), a modified version of Proof of Stake that offers higher efficiency, decentralization, and is more environmentally-friendly. Built atop of U2U Chain, U2U Subnet is a disruptive scaling solution that makes unlimited scalability possible. By implementing an innovative technology called Universal Messages Verification (UMV) and OstracismVM - an original virtual machine, U2U Subnet is able to provide seamless connectivity and interoperability. With a focus on energy efficiency, how is U2U Network contributing to the broader conversation around sustainability in blockchain technology? Ishan Pandey: U2U Network is tailored for enterprise purposes, with a strong focus on prioritizing Environmental, Social, and Governance (ESG) concerns. Not many blockchains have a business strategy aimed at ESG commitments, which is being considered by the UN as a focus in the green development program and aiming to reduce carbon emissions. U2U Network, consequently, is a pioneer not only towards sustainable development but also towards building a green blockchain ecosystem, dedicated to improving the environment of our common home Earth. Trung Trang Nguyen: Lastly, what message would you like to share with aspiring blockchain developers and entrepreneurs who look up to U2U Network? Ishan Pandey: To the aspiring blockchain developers and entrepreneurs who find inspiration in U2U Network's achievements, your ambition and dedication are truly commendable. In a rapidly evolving field like blockchain, your enthusiasm and willingness to innovate are crucial for shaping the future of technology and business. U2U Network's success story is not just a testament to what has been achieved, but also a beacon of what can be accomplished with persistence, creativity, and a deep understanding of the blockchain landscape. Trung Trang Nguyen: We appreciate your efforts in pursuing this path and encourage you to continue exploring, learning, and innovating. Your role in this transformative era of technology is essential, and your potential contributions to the field are eagerly anticipated. U2U Network stands as a source of inspiration, reminding us all of the remarkable achievements that are possible in the world of blockchain when driven by passion, intelligence, and a commitment to excellence.

53 Stories To Learn About Containerization

THE MOUNTAINS AND PLAINS OF THE MOON, AND THE SPECTACLES OF THE SUN

I reached out to my clients and asked them to identify the most pressing challenges and opportunities that blockchain startups will face in 2023. The ideas they shared with me ranged from the growth and evolution of Web3 games and mobile blockchain access to the exploration of advanced cryptographic techniques and the potential of decentralized finance. Here are five areas represent exciting builder-worthy pursuits that have the potential to shape the startup landscape in the year ahead. 1. The Future of Web3 Gaming: Fun and Functionality As the market shifts, top web3 studios are focusing on creating enjoyable, sustainable games that utilize blockchain technology. This means going back to the basics and considering the target audience, designing a game that exceeds their expectations, and determining the role of cryptocurrency in the overall experience. Developers will also be testing to ensure that their games are truly fun. , gaming activity accounted for nearly half of all blockchain activity in October and November 2022. This trend was further highlighted in November, when a record-high 800,875 daily Unique Active Wallets (UAW) interacted with the smart contracts of these games. It is clear that Web3 games are a vital player in the world of decentralized applications, and their continued growth and innovation will undoubtedly have a significant impact on the industry as a whole. According to DappRadar 2. Mobile Blockchain Access: Light Clients and Decentralization Many blockchain users rely on their smartphones for internet access, but this often requires centralized infrastructure that can be risky. The development of "light" clients like Helios, Kevlar, and Nimbus allows users to verify blockchain data directly from their devices, leading to greater decentralization for mobile frontends. A light client, also known as a lightweight or thin client, is a blockchain software program that allows users to interact with a blockchain network without downloading the entire blockchain. This can be particularly useful for mobile users who may not have the storage or processing power to run a full node. 3. Advanced Cryptographic Techniques: ZK Systems, MPC, and Post-Quantum Crypto Zero knowledge systems, multi-party computation, and post-quantum cryptography are all important technologies in the world of blockchain. However, there are trade-offs to consider in terms of prover efficiency, proof succinctness, and trusted setup requirements. In the coming year, it will be interesting to see if new constructions for zk-proofs can address these trade-offs and whether constant-size proofs can be achieved without the need for a trusted setup. , which eliminate the need to trust a single signer and are useful for distributed computation on private data, also have room for improvement in terms of minimizing the number of rounds required. As post-quantum signatures near standardization, it will be valuable to examine their potential for use in aggregation or threshold signature schemes. Threshold ECDSA signatures 4. Cryptocurrency's Potential to Expand Financial Access Cryptocurrency has the potential to provide financial services to underserved or excluded individuals, particularly in developing countries. In the year ahead, it will be interesting to see how cryptocurrency can be used for remittances, peer-to-peer lending, and other financial services. According to a , remittances to developing countries reached a record high of $626 billion in 2022, and the use of cryptocurrency for these transactions could help reduce costs and increase speed and security. World Bank report 5. DeFi and Central Bank Digital Currencies: Disruption and Implementation Decentralized finance (DeFi) has the potential to shake up traditional financial services and offer new products and services. It will be interesting to see how DeFi evolves in the coming year and what impact it has on traditional financial institutions. After the FTX collapse, DeFi saw a significant increase in activity, with a from October to November ($97 billion). This demonstrates the value of DeFi: through the use of secure smart contracts to govern assets, users can gain greater insight into liquidity and have more control over their investments. 68% rise in volumes Central bank digital currencies (CBDCs) are another area to keep an eye on. While CBDCs offer many benefits, such as increased financial inclusion and faster payment processing, they also bring up questions and concerns around privacy, monetary policy, and financial stability. It will be interesting to see how these issues are addressed and how CBDCs are implemented and adopted.

The Odyssey, by Homer and translated by Samuel Butler is part of HackerNoon’s Book Blog Post series. You can jump to any chapter in this book . here PREFACE TO FIRST EDITION This translation is intended to supplement a work entitled “The Authoress of the Odyssey”, which I published in 1897. I could not give the whole “Odyssey” in that book without making it unwieldy, I therefore epitomised my translation, which was already completed and which I now publish in full. I shall not here argue the two main points dealt with in the work just mentioned; I have nothing either to add to, or to withdraw from, what I have there written. The points in question are: (1) that the “Odyssey” was written entirely at, and drawn entirely from, the place now called Trapani on the West Coast of Sicily, alike as regards the Phaeacian and the Ithaca scenes; while the voyages of Ulysses, when once he is within easy reach of Sicily, solve themselves into a periplus of the island, practically from Trapani back to Trapani, via the Lipari islands, the Straits of Messina, and the island of Pantellaria. (2) That the poem was entirely written by a very young woman, who lived at the place now called Trapani, and introduced herself into her work under the name of Nausicaa. The main arguments on which I base the first of these somewhat startling contentions, have been prominently and repeatedly before the English and Italian public ever since they appeared (without rejoinder) in the “Athenaeum” for January 30 and February 20, 1892. Both contentions were urged (also without rejoinder) in the Johnian “Eagle” for the Lent and October terms of the same year. Nothing to which I should reply has reached me from any quarter, and knowing how anxiously I have endeavoured to learn the existence of any flaws in my argument, I begin to feel some confidence that, did such flaws exist, I should have heard, at any rate about some of them, before now. Without, therefore, for a moment pretending to think that scholars generally acquiesce in my conclusions, I shall act as thinking them little likely so to gainsay me as that it will be incumbent upon me to reply, and shall confine myself to translating the “Odyssey” for English readers, with such notes as I think will be found useful. Among these I would especially call attention to one on xxii. 465-473 which Lord Grimthorpe has kindly allowed me to make public. I have repeated several of the illustrations used in “The Authoress of the Odyssey”, and have added two which I hope may bring the outer court of Ulysses’ house more vividly before the reader. I should like to explain that the presence of a man and a dog in one illustration is accidental, and was not observed by me till I developed the negative. In an appendix I have also reprinted the paragraphs explanatory of the plan of Ulysses’ house, together with the plan itself. The reader is recommended to study this plan with some attention. In the preface to my translation of the “Iliad” I have given my views as to the main principles by which a translator should be guided, and need not repeat them here, beyond pointing out that the initial liberty of translating poetry into prose involves the continual taking of more or less liberty throughout the translation; for much that is right in poetry is wrong in prose, and the exigencies of readable prose are the first things to be considered in a prose translation. That the reader, however, may see how far I have departed from strict construe, I will print here Messrs. Butcher and Lang’s translation of the sixty lines or so of the “Odyssey.” Their translation runs: Tell me, Muse, of that man, so ready at need, who wandered far and wide, after he had sacked the sacred citadel of Troy, and many were the men whose towns he saw and whose mind he learnt, yea, and many the woes he suffered in his heart on the deep, striving to win his own life and the return of his company. Nay, but even so he saved not his company, though he desired it sore. For through the blindness of their own hearts they perished, fools, who devoured the oxen of Helios Hyperion: but the god took from them their day of returning. Of these things, goddess, daughter of Zeus, whencesoever thou hast heard thereof, declare thou even unto us. Now all the rest, as many as fled from sheer destruction, were at home, and had escaped both war and sea, but Odysseus only, craving for his wife and for his homeward path, the lady nymph Calypso held, that fair goddess, in her hollow caves, longing to have him for her lord. But when now the year had come in the courses of the seasons, wherein the gods had ordained that he should return home to Ithaca, not even there was he quit of labours, not even among his own; but all the gods had pity on him save Poseidon, who raged continually against godlike Odysseus, till he came to his own country. Howbeit Poseidon had now departed for the distant Ethiopians, the Ethiopians that are sundered in twain, the uttermost of men, abiding some where Hyperion sinks and some where he rises. There he looked to receive his hecatomb of bulls and rams, there he made merry sitting at the feast, but the other gods were gathered in the halls of Olympian Zeus. Then among them the father of men and gods began to speak, for he bethought him in his heart of noble Aegisthus, whom the son of Agamemnon, far-famed Orestes, slew. Thinking upon him he spake out among the Immortals: ‘Lo you now, how vainly mortal men do blame the gods! For of us they say comes evil, whereas they even of themselves, through the blindness of their own hearts, have sorrows beyond that which is ordained. Even as of late Aegisthus, beyond that which was ordained, took to him the wedded wife of the son of Atreus, and killed her lord on his return, and that with sheer doom before his eyes, since we had warned him by the embassy of Hermes the keen-sighted, the slayer of Argos, that he should neither kill the man, nor woo his wife. For the son of Atreus shall be avenged at the hand of Orestes, so soon as he shall come to man’s estate and long for his own country. So spake Hermes, yet he prevailed not on the heart of Aegisthus, for all his good will; but now hath he paid one price for all.’ And the goddess, grey-eyed Athene, answered him, saying: ‘O father, our father Cronides, throned in the highest; that man assuredly lies in a death that is his due; so perish likewise all who work such deeds! But my heart is rent for wise Odysseus, the hapless one, who far from his friends this long while suffereth affliction in a sea-girt isle, where is the navel of the sea, a woodland isle, and therein a goddess hath her habitation, the daughter of the wizard Atlas, who knows the depths of every sea, and himself upholds the tall pillars which keep earth and sky asunder. His daughter it is that holds the hapless man in sorrow: and ever with soft and guileful tales she is wooing him to forgetfulness of Ithaca. But Odysseus yearning to see if it were but the smoke leap upwards from his own land, hath a desire to die. As for thee, thine heart regardeth it not at all, Olympian! What! Did not Odysseus by the ships of the Argives make thee free offering of sacrifice in the wide Trojan land? Wherefore wast thou then so wroth with him, O Zeus?’ The “Odyssey” (as every one knows) abounds in passages borrowed from the “Iliad”; I had wished to print these in a slightly different type, with marginal references to the “Iliad,” and had marked them to this end in my MS. I found, however, that the translation would be thus hopelessly scholasticised, and abandoned my intention. I would nevertheless urge on those who have the management of our University presses, that they would render a great service to students if they would publish a Greek text of the “Odyssey” with the Iliadic passages printed in a different type, and with marginal references. I have given the British Museum a copy of the “Odyssey” with the Iliadic passages underlined and referred to in MS.; I have also given an “Iliad” marked with all the Odyssean passages, and their references; but copies of both the “Iliad” and “Odyssey” so marked ought to be within easy reach of all students. Any one who at the present day discusses the questions that have arisen round the “Iliad” since Wolf’s time, without keeping it well before his reader’s mind that the “Odyssey” was demonstrably written from one single neighbourhood, and hence (even though nothing else pointed to this conclusion) presumably by one person only—that it was written certainly before 750, and in all probability before 1000 B.C.—that the writer of this very early poem was demonstrably familiar with the “Iliad” as we now have it, borrowing as freely from those books whose genuineness has been most impugned, as from those which are admitted to be by Homer—any one who fails to keep these points before his readers, is hardly dealing equitably by them. Any one on the other hand, who will mark his “Iliad” and his “Odyssey” from the copies in the British Museum above referred to, and who will draw the only inference that common sense can draw from the presence of so many identical passages in both poems, will, I believe, find no difficulty in assigning their proper value to a large number of books here and on the Continent that at present enjoy considerable reputations. Furthermore, and this perhaps is an advantage better worth securing, he will find that many puzzles of the “Odyssey” cease to puzzle him on the discovery that they arise from over-saturation with the “Iliad.” Other difficulties will also disappear as soon as the development of the poem in the writer’s mind is understood. I have dealt with this at some length in pp. 251-261 of “The Authoress of the Odyssey”. Briefly, the “Odyssey” consists of two distinct poems: (1) The Return of Ulysses, which alone the Muse is asked to sing in the opening lines of the poem. This poem includes the Phaeacian episode, and the account of Ulysses’ adventures as told by himself in Books ix.-xii. It consists of lines 1-79 (roughly) of Book i., of line 28 of Book v., and thence without intermission to the middle of line 187 of Book xiii., at which point the original scheme was abandoned. (2) The story of Penelope and the suitors, with the episode of Telemachus’ voyage to Pylos. This poem begins with line 80 (roughly) of Book i., is continued to the end of Book iv., and not resumed till Ulysses wakes in the middle of line 187, Book xiii., from whence it continues to the end of Book xxiv. In “The Authoress of the Odyssey”, I wrote: the introduction of lines xi., 115-137 and of line ix., 535, with the writing a new council of the gods at the beginning of Book v., to take the place of the one that was removed to Book i., 1-79, were the only things that were done to give even a semblance of unity to the old scheme and the new, and to conceal the fact that the Muse, after being asked to sing of one subject, spend two-thirds of her time in singing a very different one, with a climax for which no-one has asked her. For roughly the Return occupies eight Books, and Penelope and the Suitors sixteen. I believe this to be substantially correct. Lastly, to deal with a very unimportant point, I observe that the Leipsic Teubner edition of 894 makes Books ii. and iii. end with a comma. Stops are things of such far more recent date than the “Odyssey,” that there does not seem much use in adhering to the text in so small a matter; still, from a spirit of mere conservatism, I have preferred to do so. Why [Greek] at the beginnings of Books ii. and viii., and [Greek], at the beginning of Book vii. should have initial capitals in an edition far too careful to admit a supposition of inadvertence, when [Greek] at the beginning of Books vi. and xiii., and [Greek] at the beginning of Book xvii. have no initial capitals, I cannot determine. No other Books of the “Odyssey” have initial capitals except the three mentioned unless the first word of the Book is a proper name. S. BUTLER. July 25, 1900.

Congrats on raising new financing for Hoken Tech. How much money did you raise? And what are the terms of the deal? Thanks, in this case, we managed to get 30 thousand euros from an Italian government fund dedicated to culture and art and in more the advantage of these funds is that only half we will have to repay over 8 years. Who participated in the round? And how will these investors help the business grow beyond the money? As previously mentioned, the main actor of these capitals derives, indirectly, from the Italian government, and this also allows us to demonstrate to everyone, how our project has the qualities and characteristics of interfacing with important institutions such as governments Worldwide. What is your company’s current valuation? What data/traction/evidence supports this valuation? We are still a young startup, but despite this, we are making great steps forward, and even the data we are collecting is encouraging and allow us to better define our goals and also the needs of users who are our first supporters. What does your company offer today? And what do you think it will provide in the future? Our business at Hoken Tech is to provide museums and artists with tools to catalyze frictionless, rapid trade of their art. We identify institutions looking for new revenue streams, facilitate the integration of the crypto-based solution, and attract visitors to museums who use QR Codes to buy the NFT too! This is not your regular art collecting closet; we can target all aspects of your business from concept to execution. In the coming months, we will present something never seen in the world, that is an NFT distributor that can be placed anywhere, as it does not require electricity or batteries, and inside it is possible to insert a capsule that contains the NFT to be redeemed, all in a decentralized way and using the EOS blockchain. What differentiates your product and/or offering from competitors? In our case, our NFTs are eco-sustainable as they exploit the EOS blockchain, and for the uninitiated, it is the first blockchain in the world to be carbon neutral, and consequently, everything created on this blockchain, including the NFTs, I can boast of this title and feature. Furthermore, we can offer an integration of these NFTs also on users' websites to integrate something decentralized on centralized portals, having the advantage of both, in fact with our solution you can sell an NFT through any payment method, which it goes from PayPal, to credit card and even bank transfer, which not everyone can offer yet on the market. Who are the founders and key team members? What exceptional skills, abilities and perspectives does this team have? Pro tip: add a picture of your team! Our team is currently made up of two members and in particular, Antonella, who holds the role of CEO of Hoken Tech, born in 1992 who, after graduating in business management, takes over the reins of the family's farm to transform it into an innovative startup of online commerce. And it represents the commercial soul of the company, essential for maintaining relationships with users of the caliber of institutions such as museums and other cultural and non-cultural bodies. Then we have Alfredo, who holds the position of CTO, and is the technological backbone of the startup thanks to his experience in the crypto and blockchain sector since 2011, he has accumulated the necessary experience to concretely develop products and services that exploit the blockchain, not to forget the numerous books also written in the blockchain field (in total he has written over 100 books), and the recent victory as Best Crypto Journalist 2021, also lies behind the NFT distributor which will be launched shortly. In laymen’s terms, how do you plan on spending the money? Half of the funds will be invested to cover all expenses related to professionals such as notaries, lawyers, and accountants to make all our operations legally proofed, to operate clearly and transparently, while the other part of the funds will be used for all the equipment and raw materials essential to operate in this area. What’s exciting about your traction to date? And how do you plan on measuring growth going forward? An important aspect of traction and the parameters to be taken into consideration is to have models and systems that are in line with our society. Obviously, as a young company, we did not have all this information but thanks to the incubation program, which we followed and won, we have learned a lot. Helios (which is part of the Helios VC in which Brok Pierce also participates), and their mentors such as Gavriel Shaw, who have provided us with several templates to use that we’ve found helpful, especially for us the SaaS template created by is proving very useful and simple compared to other templates. Christoph Janz What are your revenue expectations over the next three years? One of our advantages is that we can diversify the various sectors in which we can operate, and therefore we can multiply our offer by the various sectors, not only therefore to the art and culture sector, but also in tourism, the product sector agri-food and more. In this sense, we have developed a 5-year projection, by inserting our various fixed costs and the potential revenues deriving from the various projects that we are going to carry out. What is your TAM (Total Addressable Market)? And what is your strategy to acquire the maximum share of this market? Our main market is the institutional one and specifically the museums, which are over 55 thousand worldwide, of which over 4 thousand in Italy (we are only talking about public museums) and we aim to offer a new form of revenue provided by the digitization of works in blockchain through NFTs. And this is where our strategy comes into action thanks to the NFT distributor as it allows us to attract visitors and at the same time be able to exploit NFTs as a form of monetization. In your funding raising pitch deck, what is your favorite slide? What problem are you solving? And Why is now the time for your company to solve this? The main problem that we are going to solve for institutions such as museums, is the recovery of capital for their structures, since, especially in Italy, most museums are free and depend on aid from the Italian government which is unfortunately not enough. This problem presents itself to us as an opportunity because thanks to NFTs the museum itself puts a new product in its catalog and in its store to be traded as if it were a poster, postcard, or catalog. In addition, thanks to the traction that the NFT sector had in 2021, many are and are approaching the same and want to integrate this technology in some way also in their company. What are the potential risks to the business? i.e. technology, regulatory, incumbents, legal, etc. One of the main problems we have, at least in Italy, is dictated by the lack of regulation, and therefore we must always be in line with what is promulgated by the Italian government and be compliant with them. In fact, having a company like ours in Italy and not abroad as most do, obliges us to follow all the laws of the country, and even if they are sometimes quite restrictive, it allows us to have a significant advantage towards competition, as it does not automatically comply with the various Italian laws, and this is why our company has relied on a law firm specialized in the crypto and blockchain sector, led by an extraordinary woman like Olivia. What intellectual and digital property does the company own? Or intend to build/own? i.e. patents, patents pending, copyrights, trade secrets, trademarks, domains, bored apes, etc. We embrace the same philosophy as the blockchain, where the code is open, public, and transparent, allowing us to be clear with everyone and provide something that others cannot provide, which is trust because if everyone knows what you do and how you do it, there is no 'it is a patent or secret that can provide the same trust as something transparent and public if it is not possible to verify it how can you trust that product, technology or patent, as you may have a patent but no one would know how it works or what secrets it hides. Regarding digital assets, we have budgeted our cryptocurrencies so as to focus ourselves on this sector and this technology, and also because the amount of cryptocurrencies that a company owns is easily controllable thanks to the blockchain and it is impossible to change even in the budgets, making us also a reliable company also from a financial and economic point of view. Why should we think Hoken Tech could grow to the moon?! The only way that companies have to grow and expand is to offer innovative and cutting-edge products, and we too, being a company operating in the sector of new technologies, must constantly evolve and always provide new solutions to everyone, and this is why we have developed the NFT distributor, something that our competitors have not and have not thought of and which is difficult to replicate, which for us is already ready to be launched on the market, and has already obtained crazy numbers at events into whom we showed it, we even had to remove it because we had blocked an entire hackathon due to our distributor NFT. Would you like to take a stab at answering some of these questions? Also check out: The link for the template is HERE. ten questions for every founder :-)

How The Italian Startup Hoken Tech Is Using Its New Funding

Abstract For the blockchain methodology, the use of distributed block relations, it's important to know how they affect the liberalization of relations in the country. The question is reasonable, and to investigate it, in many countries there are already prerequisites, projects. The essence of the blockchain methodology reflects the principle of mathematical calculation of the value of a cryptographic hash function. When successfully solving this problem, a new block is added to the cryptosystem, with a small reward in cryptocurrency for the solved mathematical problem. Each token (block) in the system has its own transaction history, a chain of transactions. In our work, we systematically analyze the problems of blockchain transaction management in the elective system and offer our solutions. Literary and analytical review The liberalization of blockchain and the democratization of the electoral system is a consequence of modern digital transformations in society, digital democracy . [1] By "electronic voting", we mean the voting procedure using scanning ballots and providing automatic counting of voter's votes, their transfer by telecommunications or mobile communications. The selective practice state is based on various technical means of electronic voting . Internet voting - on the website, on a special interface service . [2] [3] Internet voting is implemented using: technically equipped booth at the polling station (Fig.1); Internet kiosks (as in the "electronic government" system) in public places; remote web voting (voting point is selected by the voter) . [4] The electoral blockchain system assumes that candidates (possible decisions made) are entered in "digital wallets" similar to cryptocurrency wallets . The voter participates in the formation of the election outcome anonymously, i.e. participates in the formation of a "portion (token)" of state power, giving his vote to the blockchain system. All voters in the peer-to-peer network connect tokens using blockchain technology and the election result is formed. [5] Any registered voter shall exercise his/her right to vote "in this place, at this time, through this communication channel". The peer-to-peer model (Р2Р) of using blockchain voting practically (if there are no critical, force majeure failures) excludes falsification of the results . [6] - [8] But so far there are many uncertainties with transactions. This leads to conflicts with the law . [9] "The state should be a digital platform for both people and cars". [10] For the first time, blockchain voting was tested in the Agora Voting project in the elections to the Spanish Cortes ]. Now used in the USA, Switzerland, Great Britain, Japan, Sierra Leone and other countries. A number of countries (Ireland, Germany, France, etc.) tested the blockchain capabilities of their electoral systems. Then they suspended testing, including by decision of the Constitutional Court, as, for example, in Germany. [11 "From bad to worse?" An article by a group of scientists from MIT made a very critical analysis of the possibilities and need to use blockchain voting systems. We will make a critical analysis of the main conclusions, theses of this article. [12] "Blockchain technology does not solve the fundamental security problems that affect all electronic voting systems". The blockchain methodology in voting systems will ensure the protection of the transfer of votes to the DB, access from the computer of each voter in the system. This is implemented programmatically, using the cryptographic code of a citizen. Although blockchain, SMART contracts are legally rejected by many, but they allow voters to have parallel access to the updated digital "book of voits" , which is unchanged in the voting process. There may be a problem with the increase in transaction processing time . [13] [14] "Electronic, online, and blockchain voting systems are more vulnerable to major disruptions than available paper-based alternatives". As the experiment with online voting in the Moscow Duma shows, in three pilot constituencies, it turned out to be successful. Of the 11,228 people who registered to participate in the electronic elections, they appeared, that is, they voted using a smartphone, computer, tablet, almost 92%. 22% of voters came to the "classic, paper" polling stations. In other European cities there is a comparable turnout . There are also "technological advantages" - few "invalid bulletins" (technical failures), and the existing ones are quite fixable during further testing of the system. As for the transition to blockchain technology, it’s systemically tested and largely verified. [15] International experts recognized that there is no such approach and results in Europe. Emmanuel Leroy, Secretary-General of the international People's Sovereignty Movement, said: "Today I saw an example of excellent work and a truly transparent process. Unfortunately, this is not the case in France". But research in this direction in Europe is underway (for example, ). [16] "Adding new technologies to elective systems can create new potential for attacks". Obviously, security problems greatly affect the block-democratization of voting. Anonymity is the main thing in any voting system. It's often impossible to track. But not in blockchain-oriented systems, the reliability of which for short-term (operational) transactions is extremely high due to the algorithms used and their reliability, estimates of traditimic complexity. And the voting period - very short - no more than 14-20 hours. Proposed solutions We offer our solutions to improve the blockchain voting system. Firstly, we believe that blockchain voting is a methodology for organizing public voting (not only elected). Therefore, it should be systematically investigated. Secondly, the blockchain also changes the performance criteria of the election system and voting system, allows you to self-tune on the profile of the voter. This will make it possible to cope with the task of preserving the secrecy of voting and confidentiality at a sufficient level. But there is a problem of mass development of blockchain technology. In Russia, this is confirmed by a survey by the National Agency for Financial Research, for example, only 4% are well aware of the system, 16% have heard about it. Therefore, we also conducted a similar survey of students. He gave, in particular, variances and deviations for the two small groups surveyed (24 and 25 person), respectively, equal to D1 = 0,005, D2 = 0,025 and S1 = 0,029, S2 = 0,086. Thirdly, to increase voter turnout, reduce fraud (see their legal classification and "portraits" in ) or combat disenfranchisement and coercion, fuzzy and neuro-systems should be used. These systems are taught ("training with a teacher" method) using examples of such violations. [17] The "binding" of the ballot to the one voting in the blockchain system is implemented, in our opinion, as in tested systems, according to the scheme: "token (voice) - transaction (submission) - confirmation (comparison with the profile of the voter) - placement in the chain (voice accounting)". Structural diagram is given in Fig.4. A good solution is offered here - the use of risk management (audit, see, for example, ) to identify vulnerabilities. As proposed by the International Association of Trusted Blockchain Applications (INATBA) for the development of blockchains in the EU. A practical solution is based on consensus algorithms and DLT development practices. [18] For the fast implementation of electronic voting in life, we need an application, very simple and easy to use. With whose help can we build the system? Let's move from theory to practice. We can take the Leo programming language as a basis, which is just adapted for building private applications. Also, to eliminate critical factors, I analyzed the work "Results of the technical audit of electronic voting on 09/08/2019 in Moscow" https://drive.google.com/file/d/1CcUXwRFCoSQ1NxzQtdwpi1spUQxSrWLE/view At all stages of interaction with an ALEO blockchain and the privacy of voting will be guaranteed by zero-knowledge protocols based on the complexity of discrete logarithms and homomorphic commitments. With this approach, the secrecy of the vote will not be violated even if it is possible to associate encrypted voter votes with specific people. In which the process of building such a system is described in sufficient detail. Since ZKP is used, you can also check if your vote passed or not. But unlike other auditors, you know that your vote is your vote. Others can see confirmation only that the vote has been received from a verified voter. Also, the voter will not be able to receive a public HASH transaction and violate the "protection against Coercion" rule (If I have a receipt, I can prove how I voted, therefore confirm to the party attempting to buy my vote.) ] [19,20,21 Voters should be able to enter their details and confirm their voting rights, but there should be no transparency of the votes cast until the end of the voting. ZKP will allow you to operate only with a verifiable anonymized hash of your right to the ballot, which is quite enough for user verification. There should be no conflicts with the transparency of the system itself. Analogs of blockchain technology can be used to develop B2B trade products and optimize financial transactions in the blockchain (for example, Commonwealth Bank of Australia). When registering and confirming your right to vote (it can be a one-time actual visit to a polling station or an entrance through a government service), you are given only a tool to activate any public key you create locally, and ZK-proof technology will allow you to do this anonymously. Subsequently, if you lose the private key from the authorized address, you can re-sign another address. In the event that this is an attempt to split the voice, then the smart contract will always find and cut off duplicates of such votes. In any case, we need to avoid such vulnerabilities as SMS verification, registration through any site with many backdoors, centralized data processing servers, PoA mechanics, and so on. The use of ALEO`s apps will increase trust in the network and increase the turnout rate and fair elections. According to a recent announcement, about $ 20 mln was spent on the Russian presidential election.[ ] 22 If we compare the ease of creating applications and, consequently, the amount for the development and maintenance of the voting system on the ALEO Blockchain, then the choice is obvious. Today, the ALEO community has all the necessary skills and resources to build this system. The question of implementation is only in the desire of the states. Conclusions To liberalize and create a democratic voting system, opportunity analytics based on blockchain technologies are necessary. First of all, in terms of predictability, security and decentralization. The analysis done in our work is the "zero turn of the evolutionary spiral", a possible part of the basis for the development of a self-developing system ("self-voting" system) based on blockchains.

Blockchain Voting - The Evolution Of Web Voting Or a New Methodology?

One of the areas where crypto and blockchain have begun to thrive is certainly that of games. At any level and thanks to this technology, we have advantages and certainties that we would hardly have with a traditional game. Just think of the fact of not having a dedicated console but of taking advantage of any type of platform, such as desktop, smartphone, or tablet to play and at any time by directly connecting your wallet, which is hardly feasible and extremely uncomfortable not to mention that these games are super safe and no one can cheat on them. Not all games are the same but one thing to keep in mind with crypto games on the blockchain is the interest of users towards them, an interest that sees precisely the reward and monetization of its assets, as a key factor in making the game interesting, and an example is that of Play to Earn (P2E) games. Today we bring to light a game, which is a game on blockchain in particular on that of EOS, where it borrows the idea of ​​another popular game that is Pokemon Go, and transports it to the crypto world by making several changes to the concept of the game itself. In fact, in the game of monsters, we will have to go around the city and the world to catch the pokemon that we will find, certainly funny but not very interesting, especially for those who are already big, in the case of The Lost Diamond instead what we will have to find will be a code, hidden from another user, located who knows where who once found could provide us with an interesting prize pool of 10 thousand dollars. In this case, the pokemon have been replaced by codes which in turn unlock a quantity of EOS generated by the smart contract and therefore no one will know if that code will be successful or not until someone enters it on the page to check the code and find out if he has won and how much he has won, as there are also codes from different EOS scattered here and there. We have talked about theory up to now but we like the practice and so let's see together how to create this code and how much it costs, so we can then create our personalized treasure hunts and challenge our city and our friends to find this code. Before we start we will need a few things: An EOS account Some EOS, even 1 is fine A wallet that supports the EOS blockchain such as Anchor Wallet Info about the position of the place where we will then place the code The first step will be to go to The Lost Diamond website here and connect our EOS account. Among other things, you can also use your phone number to log in: At this point we will have to go to our account by clicking on the top right, and then go to the checkpoint section, to start the procedure: Here we will have to start the procedure by clicking on the "Add new checkpoint" button and in the next window we will have to enter all the information about this checkpoint such as image, place, and other information: Then we click on "Next" to better arrange the point on the map with the correct geographic coordinates, then again on "Next", and here we have to accept the conditions and pay for the creation of the checkpoint which is a total of $ 1 about 0.5 EOS: Once we have created the checkpoint, we will find it in the checkpoints section on our account: The great thing about this game is that not only does it allow the treasure hunter to win a prize pool of 10 thousand dollars, but it also allows the creator of the code to get the same amount won by the discoverer, and in this way, everyone is encouraged both to search these codes than to create them. In this way, various results and positive effects are obtained: You can win a prize in EOS and therefore of value without any intermediaries or fuss in the procedure It encourages you to go outdoors and spend a nice day in the company as you know in advance where to go Those who have no experience with crypto and blockchain have one more reason to find out about this world For those who create the code, a second profitable income is being created Finally, we remind you that this project was born from a Norwegian team and that it also participated in the incubation plan of Helios, which is part of an important investment fund focused on EOS and EOSIO, demonstrating how this project, launched in 2019 and still and super active after all these years, both a project and a super interesting dApp for everyone and the EOS ecosystem. We end with the video that I made for Italian readers where I explain the steps: https://youtu.be/sL6fChkEPaA
