海外TECH	DEV Community	Roadmap to Blockchain Development	https://dev.to/siddharthsing/roadmap-to-blockchain-development-on4	Roadmap to Blockchain DevelopmentTo know how blockchain and web are the new internet click here In this roadmap to blockchain development I will be suggesting some of the learning resources as we walk through Also this article series on dev to will also guide you through these topics one by one Two types of blockchain developersThere are two types of blockchain developers present One who builds the blockchain from scratch for example Bitcoin creator Satoshi Nakamoto or Ethereum creator Vitalik Buterin and others who build Decentralised Applications dApps upon the public blockchains already present In general when we say blockchain developer we mean the dApp Decentralised Apps developers who develop apps upon publicly available blockchain networks In this roadmap to blockchain development I will be walking through all the topics to cover to become an Ethereum blockchain developer Also I will be suggesting some of the learning resources This article series on blockchain will also guide you through these topics one by one Start with Basics Since blockchain technology is new in comparison to Android or Web Dev the community of Blockchain Developers is limited So it s crucial to have a good grasp on the foundation or the basics of blockchain Blockchain foundation and use cases Week Why are People Excited About Blockchain The Brief History of Blockchain The Move to Decentralization Ledgers Distributed Ledgers and Consensus What is Blockchain Week Basics of cryptography and hash Functions Public Key Cryptography and Signing Blocks and Blockchain Structure of a block Nodes and Network Week Trust Framework and Consensus Mechanisms Public Consortium Private BlockchainsBlockchain InteroperabilityWhen to Use a Blockchain Limitations and Misconceptions Implications of Blockchain on Traditional Business Week Bitcoin and Ethereum Ethereum BlockchainSmart Contracts Theory Cryptocurrency TokensWallets and the MarketplacesImplications on Traditional Businesses This foundation course is offered by the Consensys Academy Why this foundation course There are several Blockchain foundation courses present on the internet Not all of them are bad but some of them are misleading I am referring to this course because this course presented by ConsenSys Academy ConsenSys is a market leading blockchain technology company and the parent company of Ethereum So why not learn something directly from its creators Click here for knowing about financial aid provided by Coursera Project based learningNow that you have cleared your basics you are good to go for the main battle The best way to learn Ethereum blockchain development is by project based learning Learn blockchain by implementing it because things are very much uncertain in the web environment Your knowledge today will not benefit you tomorrow So try and learn by doing projects and keep yourself updated with the trend Let us list some bare minimum needed tools and technologies to learn Ethereum Blockchain Development JavascriptJavascript is a very versatile programming language It can be used almost everywhere hence making it an indispensable part of blockchain development Mainly react js node js express js and web js libraries of Javascript are needed in blockchain development Note We can also use Python in place of Javascript and the web py library of python instead of web js But javascript is recommended SoliditySmart contract is a computer program or a transaction protocol that is intended to automatically execute control or document events and actions according to the terms of a contract or an agreement written in Solidity language In short solidity is the coding language that one has to learn to become an Ethereum blockchain developer TruffleTruffle is a world class development environment testing framework and asset pipeline for blockchains using the Ethereum Virtual Machine EVM aiming to make life as a developer easier GanacheGanache is used for setting up a personal Ethereum Blockchain for testing your Solidity contracts It provides more features when compared to Remix You will learn about the features when you work out with Ganache Metamask Metamask is a cryptocurrency wallet that is available as a browser extension Since web applications are not compatible to run with our normal browser metamask overcomes this threshold You will be learning about metamask more as you go forward Learning all these technologies with project based implementation will make your blockchain journey far ahead of many developers because there are only roughly blockchain developers available among all million developers Now I will suggest courses for Ethereum Blockchain Development which I find great Ethereum Blockchain Developer Bootcamp With Solidity This is a paid course but the authors are great tutors and all course materials got updated on a regular basis Ethereum Development Course Blockchain at BerkeleyThis is a freely available course on Udemy offered by Blockchain at Berkley Blockchain SpecializationThis is again a paid course but you can apply for financial aid on Coursera and your financial aid will be cleared within days Click here to know how to apply for the financial aid

海外TECH	Engadget	Everything NASA is taking to the moon before colonizing Mars	https://www.engadget.com/nasa-artemis-program-explained-moon-mars-colonization-video-143013129.html?src=rss	Everything NASA is taking to the moon before colonizing MarsAmid the pantheon of Greek gods few are more revered than Artemis Goddess of the hunt chastity and the moon Mistress of Animals Daughter of Zeus and twin sister to Apollo Famed for her pledge to never marry feared from that time she turned the peeping Acteon into a stag and set his own hunting dogs upon him Artemis has stood as a feminist icon for millenia It seems only fitting then that NASA names after her a trailblazing mission that will see both the first woman and first person of color set foot on the moon ahead of humanity s first off planet colony In fact NASA has been naming its missions after Zeus progeny since the advent of spaceflight There was the Mercury Program the Roman spelling of Hermes in then Gemini in followed by Apollo in NASA took a quick break on the naming convention during the Shuttle era but revived it when it formally established the Artemis program in Working with the European Space Agency ESA Japan Aerospace Exploration Agency JAXA Canadian Space Agency CSA and a slew of private corporations NASA s goal for Artemis is simple to re establish a human foothold on the moon for the first time since and stay there NASA is building a coalition of partnerships with industry nations and academia that will help us get to the moon quickly and sustainably together then NASA director Jim Bridenstine said in “Our work to catalyze the US space economy with public private partnerships has made it possible to accomplish more than ever before The budget we need to achieve everything laid out in this plan represents bipartisan support from the Congress “Under the Artemis program humanity will explore regions of the moon never visited before uniting people around the unknown the never seen and the once impossible he continued “We will return to the moon robotically beginning next year send astronauts to the surface within four years and build a long term presence on the Moon by the end of the decade Red Huber via Getty ImagesJust as Artemis the Goddess grew out of earlier pre Hellenistic mythology Artemis the Program was born from the ashes of the earlier Constellation program from the early s which sought to land on the moon by ーspecifically the Ares I Ares V and Orion Crew Exploration Vehicle that were developed as part of that effort In then President Barack Obama announced that the non Orion bits of Constellation were being axed and simultaneously called for billion in additional funding as well as the development of a new heavy lift rocket program with a goal of putting humans on Mars by the mid s This became the NASA Authorization Act of and formally kicked off development of the Space Launch System the most powerful rocket NASA has built to date The Artemis program was helped further in December of when former President Donald Trump signed Space Policy Directive SPD That policy change “provides for a US led integrated program with private sector partners for a human return to the moon followed by missions to Mars and beyond and authorized the campaign that would become Artemis two years later In then Vice President Mike Pence announced that the program s goals were accelerating the moon landing goal pushed up four years to though its original goal of Mars in the s remained unchanged “The directive I am signing today will refocus America s space program on human exploration and discovery Trump said at the time “It marks a first step in returning American astronauts to the moon for the first time since for long term exploration and use This time we will not only plant our flag and leave our footprints ーwe will establish a foundation for an eventual mission to Mars and perhaps someday to many worlds beyond Bang zoom straight to the moonNASANow we know NASA can put people on the moon ーit s the keeping them there alive that s the issue The moon for all its tide inducing benefits here on Earth is generally inhospitable to life what with its general lack of breathable atmosphere and liquid water weak gravity massive temperature swings and razor sharp statically charged dust The first colonists will need power heat atmosphere potable water ーall of which will have to either be brought from Earth or extracted locally from the surrounding regolith Complicating matters the Moon at miles away is about a thousand times farther than the International Space Station and getting a crew with everything they need to survive for more than a few days is going to require multiple trips ーnot just from Earth orbit to the moon but also from lunar orbit down to the surface and back But high risk high reward logistical nightmares are kind of NASA s whole deal As such the Artemis program is split between the SLS missions which will eventually bring the human crew to the moon and the support missions which will bring everything else That includes robotic rovers the Human Landing System as well as moonbase and Gateway components along with all of the logistical support and infrastructure that they will require Artemis SLS missionsThe SLS missions are built around NASA s new Deep Space Exploration System which comprises the SLS super heavy lift launch vehicle the Orion Spacecraft and the Exploration Ground Systems at Kennedy Space Center KSC NASANASA s deep space exploration systemThe Space Launch System is the single most powerful rocket humanity has built and given its modular evolvable design will likely continue to be for the foreseeable future Its initial configuration dubbed Block consists of just the core stage with four RS engines and two five segment solid rocket boosters Once the SLS breaks atmosphere its Interim Cryogenic Propulsion Stage takes over for in space propulsion Those RS s are the same engines that flew on the Space Shuttle Aerojet Rocketdyne of Sacramento California is updating and upgrading of them for use in the modern era ーbringing them up to standard for use with the SLS ーwith a new engine controller new nozzle insulation and pounds of thrust Altogether the core stage will produce million pounds of thrust and be capable of pushing metric tons sqft of cargo out to the moon at speeds in excess of miles per hour The Artemis mission that launched in November as well as the next two Artemis missions are slash will be powered by Block rockets NASABlock B rockets will include an Exploration Upper Stage EUS built by Boeing and composed of “four RLC engines that produce almost four times more thrust than the one RLB engine that powers the ICPS per NASA That additional engine will enable the space agency to haul tons of cargo out of Earth s gravity well This updated block will provide NASA a bit more flexibility in its launches A B rocket can be configured to lift the Orion spacecraft or cargo loads into deep space as easily as it can be for hauling large cargoes to the moon or Mars NASA plans to lift unwieldy portions of the moonbase and Gateway into space with it The SLS final form for now will be Block Standing more than stories tall weighing the equivalent of fully loaded s the block blasting million pounds of thrust percent more than the Saturn V to push metric tons of stuff taking up as much as square feet into deep space Once that configuration comes online NASA expects it to take on much of the heavy lifting sorry not sorry in delivering crews and cargo to the moon Orion spacecraftRiding atop the SLS s multi ton controlled explosions is the Orion Spacecraft the first crew capsule designed for deep space exploration in more than a generation Designed and built with help from the ESA the Orion sandwiches a four person crew cabin in between a services module that holds all of the important life support navigation and propulsion systems and a Launch Abort System LAS that will forcibly eject the crew capsule from the larger launch vehicle if a catastrophic failure occurs during takeoff The foot tall LAS weighs pounds and is designed to engage within milliseconds of a launch going sideways lifting the crew cabin away from the rest of the SLS at Mach using the pounds of thrust produced by the abort motor Its attitude control motor provides another pounds of thrust to keep the capsule upright during escape while the jettison motor will separate the LAS from the cabin once clear the latter deploying a parachute ahead of its upcoming water landing The LAS actually predates Orion by four years The LAS was first integrated into a Delta IV and flown at the White Sands test facility in New Mexico in while the uncrewed Orion Exploration Flight Test didn t take off for its four hour two orbit jaunt until The Orion main cabin is just under feet tall and just over feet in diameter Its four wing solar array produces kW of power and the attached service module holds enough air and water to keep the crew alive if a bit panicked and sir crazy for up to three weeks Exploration ground systemsHandout via Getty ImagesLocated at the Kennedy Space Center in Florida the Artemis program s Exploration Ground Systems EGS is tasked with developing and enacting the facilities and operations necessary to conduct SLS missions That includes the Vehicle Assembly Building the Launch Control Center the Firing Rooms Mobile Launchers and the Crawlers that haul rockets out to the launchpads and also the launchpads ーspecifically Launch Pad B Teams have been working to modernize many of those facilities and NASA notes that it “has successfully upgraded its processes facilities and ground support equipment to safely handle rockets and spacecraft during assembly transport and launch NASA already has five main Artemis launches scheduled The uncrewed Artemis I again successfully launched in November Artemis II which will carry four live astronauts for the first time but only loop around the moon launches in Artemis III will go up in and is expected to be the first to actually set down on the moon Artemis IV is slated for and will deliver half of the lunar Gateway as well as debut the EUS while Artemis V is set to deliver the other half of the Gateway in From there NASA has some thoughts on Artemis missions VI through X but has not finalized any details as of yet Artemis support missions“We need several years in orbit and on the surface of the moon to build operational confidence for conducting long term work and supporting life away from Earth before we can embark on the first multi year human mission to Mars Bridenstine said in “The sooner we get to the moon the sooner we get American astronauts to Mars NASABut before we can build confidence in our ability to survive on Mars we need to build confidence in our ability to survive on the moon The Artemis support missions will do just that The Capstone Mission quot Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment quot for example successfully launched a pound cubesat in June to confirm NASA s math for the much larger Gateway s future orbital path While in orbit the Capstone will communicate and coordinate some of its maneuvers with the Lunar Reconnaissance Orbiter which has been circling the moon since In NASA also plans to launch the VIPER robotic rover to the moon s South Pole where it will search the lowest darkest coldest craters for accessible water ice Finding a source for HO is of paramount importance to the long term viability of the colony In space water isn t just for drinking and bathing ーit can be split into its component atoms and used to fuel our oxidizing rockets potentially turning the Moon into an orbital gas station as we push farther out from Earth The rover and others like it will be delivered to the surface as part of NASA s Commercial Lunar Payload Services CLPS program It wasn t until the mid s that NASA even confirmed the presence of water ice on the moon and only two years ago did they discovered ice accessible from the moon s surface “We had indications that HO the familiar water we know might be present on the sunlit side of the moon Paul Hertz director of the Astrophysics Division in the Science Mission Directorate at NASA Headquarters said at the time “Now we know it is there This discovery challenges our understanding of the lunar surface and raises intriguing questions about resources relevant for deep space exploration Similarly any habitat established on the surface will need an ample supply of electricity to remain online Solar charging is one obvious choice that lack of atmosphere is finally coming in handy but NASA has never been one to underprepare and has already selected three aerospace companies to develop nuclear power sources for potential deployment GatewayNASAIn addition to a surface installation NASA plans on putting a full fledged space station dubbed the Lunar Gateway into orbit around the moon where it will serve much the same purpose as the ISS does today Visiting researchers will stay aboard the pressurized Habitation and Logistics Outpost HALO module where they ll have access to research facilities remote rover controls and docking for both Orion capsules from Earth and HLS Human Landing System landers to the moon s surface A kW solar plant will provide power to the station which also serves as a communications relay hub with the planet The station s position around the moon will also provide a unique astronomical perspective for future research The Gateway will very much be an international operation As NASA points out Canada s CSA is providing “advanced robotics for use upon the station the ESA is supplying a second living module called the International Habitat IHab as well as the ESPRIT communications module and an array of research cubesats Japan s JAXA will kick in additional habitat components and assist with resupply logistics Human Landing System and roversFrom the Gateway astronauts and researchers will ferry down to the moon s surface to collect samples run experiments and conduct observations aboard the Human Landing System a reusable lunar lander program currently being operated out of Marshall Space Flight Center in Huntsville Alabama NASA selected SpaceX s Starship for its initial landing system in April awarding the company billion to further the vehicle s development The agency then awarded SpaceX with another billion this past November as part of the Option B contract modification The extra money will help fund planned upgrades to the spacecraft which is being modified from the base Starship design for use on and around the moon s surface “Continuing our collaborative efforts with SpaceX through Option B furthers our resilient plans for regular crewed transportation to the lunar surface and establishing a long term human presence under Artemis Lisa Watson Morgan NASA HLS program manager said in November “This critical work will help us focus on the development of sustainable service based lunar landers anchored to NASA s requirements for regularly recurring missions to the lunar surface Researchers however will not be content to travel nearly a quarter million miles just to set down on the moon and look out the lander s windows Instead they ll be free to wander around the surface safely ensconced in spacewalk equipment supplied by Axiom Space and Collins Aerospace “With these awards NASA and our partners will develop advanced reliable spacesuits that allow humans to explore the cosmos unlike ever before said Vanessa Wyche director of NASA s Johnson Space Center in Houston said in June “By partnering with industry we are efficiently advancing the necessary technology to keep Americans on a path of successful discovery on the International Space Station and as we set our sights on exploring the lunar surface Those researchers won t be on foot either Just as the Apollo astronauts famously bounced around on NASA s first gen lunar rovers the Artemis missions will use new Lunar Terrain Vehicles The unpressurized buggies are currently still in development but NASA expects to have a finalized proposal ready by next year and have the LTVs ready for surface service by The Artemis Base CampWhen not in use the LTVs will be parked at NASA s Artemis Base Camp at the lunar South Pole alongside a pressurized version designed for longer duration expeditions The surface habitat itself will be able to support up to four residents at a time and provide communications equipment storage power and most importantly robust radiation shielding and there s the downside of not having an atmosphere A site hasn t yet been officially selected though mission planners are looking for areas near the region s permanently shadowed craters where water ice is expected to be most easily accessible aside from the negative degree temperatures and perpetual darkness “On each new trip astronauts are going to have an increasing level of comfort with the capabilities to explore and study more of the moon than ever before Kathy Lueders associate administrator for human spaceflight at NASA Headquarters said in “With more demand for access to the moon we are developing the technologies to achieve an unprecedented human and robotic presence miles from home Our experience on the moon this decade will prepare us for an even greater adventure in the universe ーhuman exploration of Mars	2022-12-15 14:30:13
海外TECH	Engadget	The best VR headsets for 2023	https://www.engadget.com/best-vr-headsets-140012529.html?src=rss	The best VR headsets for If you ve been holding out for VR hardware to mature you chose wisely Headsets have come a long way since the launch of the Oculus Rift and HTC Vive six years ago The Meta Quest has already been around for two years and it s proven to be a very capable portable VR experience And if you re looking for a more immersive experience high end PC headsets are getting cheaper and there s the new PS VR to look forward to While the overall VR market hasn t really changed much since last year aside from the somewhat disappointing Meta Quet Pro at least there are plenty of VR experiences to dive into So what makes a good VR headset I tend to judge them on a few basic criteria Ergonomics immersion and controls It s not that hard to shove a mobile display into a plastic headset and strap some cheap elastic headbands onto it But it takes skill to craft something that s well balanced and doesn t feel uncomfortable after minutes Immersion meanwhile comes from having high resolution screens with fast refresh rates so everything looks sharp and smooth Field of view is also a major element as it describes how well VR screens can cover what you see Having a low field of view makes it feel like you re looking through a pair of binoculars which limits your sense of “presence But a wide field of view can make it seem like you re actually flying over the globe in GoogleEarth And when it comes to controllers the best options fit naturally in your hands and offer accurate tracking The industry has basically adopted the design of Meta s excellent touch controllers but we re also seeing intriguing leaps forward like Valve s finger tracking gamepads Best VR headset for most people Meta Quest Over two years since its release the Meta Quest remains the best VR option for the vast majority of consumers It s completely cordless and it s comfortable to wear for long sessions Unfortunately due to supply chain pressures and a worsening economic climate Meta ended up increasing the Quest s price by this year making it a headset It s still a great device but it s also in the strange position of being a worse deal than it was last year Here s what s still good though there s a huge library of titles that you can experience anywhere and it s bundled with Meta s great motion controllers You can also connect the Quest to a gaming PC to stream more complex VR experiences The Quest features fast switching LCDs with a resolution x per eye the highest we ve seen from Meta It also has a smooth Hz refresh rate which is impressive for something running entirely on mobile hardware The Quest s field of view isn t the best ーit s been measured at just around degrees ーbut it s still enough to enjoy most VR experiences You can also use different face pads to increase its field of view a bit And if you want an even more comfortable fit you can snag the Elite headstrap for or with a built in battery and case Meta has recalled the foam inserts from the original model and is offering silicone covers to make the headset more comfortable We didn t experience any issues during our review or during the past year of usage but there have been enough complaints for Facebook to take action The base Quest also comes with GB of storage double the space of the original model giving you even more room to cram in games and VR apps The Quest may not offer the best overall VR experience but it s certainly the most accessible headset on the market At least until we see a potential follow up next year Best PC VR headset under HP Reverb GIf you don t care about wireless VR and you want to invest a bit more in a high quality PC headset HP s Reverb G is meant for you It was developed in cooperation with Valve and has some of the best features from the pricier Index headset like near field speakers The Reverb G also has sharp screens offering by pixels per eye a Hz refresh rate and a relatively wide degree field of view It s also the first Windows Mixed Reality headset to include four sensors which helps to ensure more accurate VR tracking especially during fast paced games I also give HP credit for making a headset that s extremely comfortable thanks to its luxurious cushioning around the eye piece and rear strap The Reverb G s motion controllers aren t my favorite but they re still a big step up from HP s previous model You could also upgrade it to use Valve s finger tracking controllers but that involves snagging SteamVR sensors and a lot more setup Still it s nice to have the upgrade path available Best PC VR headset for gamers Valve IndexValve s Index kit remains one of the best high end VR solutions on the market For you get the Index headset Valve s finger tracking controllers and two SteamVR base stations While we ve seen higher resolution headsets arrive in the last two years it s still a very solid option with a by pixel resolution an eye watering Hz refresh rate and a massive degree field of view I d gladly lose a few pixels to get a smoother and more expansive screen which are still far beyond any other consumer headset As a SteamVR product the Index requires installing two sensors at opposite corners of your room And of course it s wired to your PC But that clunkiness is worth it for the higher refresh rate and more accurate tracking Sure it s not as easy to use as the Quest but at this price range we assume you ll suffer a bit of inconvenience to get a truly high quality VR experience Valve s finger tracking controllers are fantastic as well with a convenient strap that locks them onto your hands They make playing Half Life Alyx feel like a dream It s unfortunate that other VR games haven t fully taken advantage of the finger tracking though Best VR quality no matter the cost HTC Vive Pro HTC s Vive Pro is the best looking PC VR I ve seen It has an astoundingly sharp K screen and a solid Hz refresh rate Just be prepared the full kit which includes the headset two SteamVR sensors and wand controllers costs You can also buy the headset separately for as an upgrade to the original Vive Pro or the Valve Index For the price you get a well balanced and supremely comfortable VR headset The Pro is a clear sign that Valve has practically perfected the art of making high end hardware I m less impressed with the large wand controllers which are exactly the same as the ones that came with the original HTC Vive in They re functional but they re nowhere near as ergonomic as Oculus s Touch Controllers I m mainly recommending the Pro here based on the astounding quality of the headset True VR fans may want to just grab that separately along with SteamVR base stations and Valve s finger tracking controllers That way you can ensure you have the best experience while playing Pistol Whip What about the PS VR We adored Sony s PlayStation VR when it launched but it s practically been ignored since the PlayStation debuted Sony s solution is the PS VR a completely revamped device with built in tracking far better resolution a larger field
