海外TECH	DEV Community	From Bits to Blockchain: The Inner Workings of Ethereum Transactions Explained	https://dev.to/sahil_4555/from-bits-to-blockchain-the-inner-workings-of-ethereum-transactions-explained-2ghn	From Bits to Blockchain The Inner Workings of Ethereum Transactions ExplainedTransactions in Ethereum are like messages that cause changes on the blockchain They are created by user accounts and processed by the Ethereum network Transactions are what make things happen and execute contracts on Ethereum Imagine Ethereum as a machine with different states Transactions are what drive this machine and make it change from one state to another Contracts which are important parts of Ethereum cannot work by themselves Ethereum doesn t run automatically everything starts with a transaction In this blog we will explain transactions how they work and their details While some of this information is more relevant to those building wallet apps or dealing with transactions at a technical level you don t need to worry about it if you use existing wallet applications However you might still find the details interesting The Structure of a TransactionA transaction in Ethereum has a specific structure when it s sent over the network However different clients and applications may add their own extra information when storing and processing the transaction internally Here are the main components of a transaction Nonce A sequence number assigned by the sender s account to prevent duplicate transactions Gas price The amount of ether in wei that the sender is willing to pay for each unit of gas used to process the transaction Gas limit The maximum amount of gas the sender is willing to use for this transaction Recipient The Ethereum address of the intended receiver of the transaction Value The amount of ether in wei to be sent to the recipient Data A variable length payload containing binary information v r s Three components used for the digital signature of the sender s account The transaction s structure is serialized using a special encoding scheme called Recursive Length Prefix RLP Ethereum uses big endian integers to represent numbers and the length of each field is identified using RLP s length prefix It s important to note that the field labels e g to gas limit mentioned here are for clarification purposes and are not part of the serialized transaction data itself RLP doesn t include field delimiters or labels Anything beyond the specified length belongs to the next field in the structure While this is the structure of the transmitted transaction most software representations and user interfaces add extra information derived from the transaction or the blockchain For example you might notice that the sender s address from data is not explicitly included in the transaction That s because the sender s public key can be derived from the ECDSA signature components v r s and the address can be derived from the public key The from field you see in transaction visualizations is added by the software for clarity Other additional information such as the block number and transaction ID is often added by client software but is not part of the original transaction message itself The Transaction NonceThe nonce is an important component of a transaction but it is often misunderstood It represents the number of transactions sent from an address or the number of contract creations made by that address However the nonce itself is not stored explicitly on the blockchain It is dynamically calculated by counting the confirmed transactions originating from an address The nonce serves two purposes maintaining the order of transactions and preventing duplication Let s consider examples for each scenario Transaction Order Imagine you want to send two transactions one for ether and another for ether You send the ether transaction first thinking it s more important and then the ether transaction However if your account doesn t have enough funds for both one transaction will fail Since transactions can reach nodes in different orders it s uncertain which one will be accepted But with the nonce the first transaction will have a specific nonce value let s say while the second transaction will have the next nonce value So the second transaction will be ignored until the previous nonces are processed ensuring the desired order of execution Duplication Protection Suppose you send a payment of ether to someone for a product Without a nonce a second transaction with the same amount to the same address would appear identical to the first one This means anyone on the network could replay your transaction multiple times potentially draining your funds However with the nonce value included in the transaction data every single transaction is unique even when sending the same amount of ether to the same recipient address multiple times Even if you send the same amount to the same recipient multiple times the incrementing nonce ensures no duplication This safeguards your payments from being exploited or replayed by others To summarize the nonce is crucial in account based protocols like Ethereum unlike the Unspent Transaction Output UTXO mechanism used in Bitcoin It maintains transaction order and prevents unauthorized duplication enhancing the security and integrity of transactions Keeping Track of NoncesThe nonce represents the count of confirmed transactions originating from an account You can obtain the nonce by querying the blockchain through a web interface gt web eth getTransactionCount xeacabbbadef The nonce is a zero based counter meaning the first transaction has nonce In this example we have a transaction count of meaning nonces through have been seen The next transaction s nonce will need to be Your wallet software keeps track of nonces for each managed address If you re building your own wallet or application you assign the next nonce when creating a new transaction However the pending transactions may not be included in the nonce count immediately It s important to wait until the pending and confirmed counts are equal before relying on the nonce from the getTransactionCount call Once the counts align you can start tracking the nonce in your application until each transaction is confirmed gt web eth getTransactionCount xeacabbbadef pending gt web eth sendTransaction from web eth accounts to xBcdfBCBbDFBcCECEbdB value web utils toWei ether gt web eth getTransactionCount xeacabbbadef pending gt web eth sendTransaction from web eth accounts to xBcdfBCBbDFBcCECEbdB value web utils toWei ether gt web eth getTransactionCount xeacabbbadef pending gt web eth sendTransaction from web eth accounts to xBcdfBCBbDFBcCECEbdB value web utils toWei ether gt web eth getTransactionCount xeacabbbadef pending When we sent the first transaction the transaction count increased to indicating a pending transaction However when we quickly sent three more transactions the getTransactionCount call didn t include them It only counted one transaction even though we expected all three to be pending in the network s memory pool mempool If we wait for a few seconds to let network communications settle the getTransactionCount call will return the expected number But during this time when there are multiple pending transactions relying on getTransactionCount may not be helpful When developing an application that creates transactions it s important not to rely on getTransactionCount for pending transactions Only when the pending and confirmed counts are the same all outstanding transactions are confirmed can you trust the getTransactionCount result and start tracking the nonce Afterward you should keep track of the nonce in your application until each transaction is confirmed Gaps in Nonces Duplicate Nonces and ConfirmationIt s crucial to keep track of nonces when creating transactions programmatically especially if you re doing so from multiple independent processes simultaneously The Ethereum network processes transactions based on their nonce in a sequential manner If you send a transaction with nonce and then another with nonce the second transaction will not be included in any blocks It will be stored in the mempool and the network will wait for the missing nonce in this case to appear Nodes assume that the missing nonce is delayed and that the transaction with nonce arrived out of order To resolve this you need to send a valid transaction with the missing nonce to allow both transactions and to be processed and included in blocks If there s a gap in the nonce sequence subsequent transactions will be stuck waiting for the missing nonce to be filled It s important to note that once a transaction with the missing nonce is validated all the subsequent transactions with higher nonces become valid It s not possible to undo or recall a transaction On the other hand if you accidentally duplicate a nonce by sending two transactions with the same nonce but different recipients or values one of them will be confirmed and the other will be rejected The confirmation of the transaction will be determined by the order in which they reach the first validating node making it somewhat random As you can see accurately managing nonces is necessary to avoid issues If your application doesn t handle nonces correctly you may encounter problems Handling nonces becomes even more challenging when dealing with concurrent transactions as we ll explore in the next section Concurrency Transaction Origination and NoncesConcurrency means multiple independent systems working at the same time In Ethereum different parts of the system can work simultaneously but they all follow the same rules to maintain consistency Imagine you have multiple wallet applications generating transactions from the same address For example an exchange processing withdrawals from its online wallet Ideally you d want multiple computers handling withdrawals to avoid slowdowns or failures However this creates problems because each computer needs to coordinate and assign nonces correctly One approach is to use a single computer to assign nonces to the computers generating transactions However this creates a single point of failure If a nonce is assigned but not used all subsequent transactions get stuck Another approach is to generate transactions without assigning a nonce leaving them unsigned These unsigned transactions can then be queued to a single node that signs them and keeps track of nonces However this creates a bottleneck as signing and tracking nonces can become congested under heavy load This approach lacks concurrency in a critical part of the process These concurrency challenges combined with the difficulty of tracking balances and confirmations in independent processes often lead to solutions that avoid concurrency For example some implementations use a single process to handle all withdrawals or set up multiple independent wallets that require occasional rebalancing In summary managing concurrency in Ethereum can be complex Practical solutions aim to balance between concurrent processing and avoiding bottlenecks in order to maintain a stable and reliable system Transaction GasGas is like the fuel used in Ethereum transactions It s not the same as ether the main cryptocurrency of Ethereum but a separate virtual currency with its own value compared to ether Gas is used to control the resources that a transaction can use because it s processed by many computers worldwide This ensures that transactions don t overload the system or consume excessive resources Gas exists separately from ether to protect the system from the rapid changes in ether s value It also helps manage the costs of different resources involved in transactions such as computation memory and storage The gasPrice field in a transaction allows the sender to choose the price they are willing to pay for gas This price is measured in wei per unit of gas For example if a transaction sets the gasPrice to gwei billion wei it means the sender is willing to pay that amount in exchange for the required gas Wallets can adjust the gasPrice in transactions to influence the speed of confirmation Higher gasPrice means faster confirmation while lower prices result in slower confirmation In some cases transactions with zero gasPrice can be fee free and still get included in blocks during periods of low demand The gasPrice can be set to zero which means wallets can create transactions without paying any fees However these transactions may not get confirmed if the network is busy The Ethereum protocol doesn t prevent free transactions and some examples of such transactions have been successfully added to the Ethereum blockchain The gasLimit field determines the maximum amount of gas the sender is willing to buy for the transaction For simple payments the gas amount needed is fixed at units To calculate the cost in ether multiply by the gasPrice For example gt web eth getGasPrice function err res console log res gt When interacting with a contract estimating the gas needed becomes challenging Contracts can have different execution paths and varying gas costs based on conditions beyond your control For instance a contract may have different outcomes after a certain number of calls resulting in different gas costs depending on prior transactions The gas needed for a contract cannot be accurately determined An analogy often used is to think of gasLimit as the fuel tank capacity for your car representing the transaction You fill the tank with an estimated amount of gas needed for the journey computation for validating the transaction However unexpected factors like diversions or complex execution paths can increase fuel consumption In Ethereum the gasLimit works more like a credit account at a gas station When you send a transaction it s validated that your account has enough ether to cover gasPrice gasLimit The actual deduction from your account occurs after the transaction finishes executing and you re billed only for the gas consumed Therefore you need to have enough balance to cover the maximum amount you re willing to pay before sending the transaction Transaction RecipientThe recipient of a transaction is specified in the to field which contains a byte Ethereum address This address can belong to an individual EOA or a contract Ethereum doesn t perform any validation on this field Any byte value is considered a valid address Whether the address corresponds to an existing private key or a contract is not verified by Ethereum If you send a transaction to the wrong address the ether sent will likely be lost forever and cannot be accessed as most addresses do not have a known private key to authorize spending Validating the address is typically done at the user interface level to prevent such mistakes Burning ether or making it unspendable can have valid reasons in some cases like discouraging cheating in payment channels or other smart contracts Since the total amount of ether is finite burning it effectively redistributes its value to all ether holders in proportion to the amount they hold Transaction Value and DataThe main payload of a transaction is contained in two fields value and data Transactions can have both value and data only value only data or neither value nor data All four combinations are valid A transaction with only value is a payment A transaction with only data is an invocation A transaction with both value and data is both a payment and an invocation A transaction with neither value nor dataーwell that s probably just a waste of gas But it is still possible Transmitting Value to EOA s and ContractsWhen you send a transaction with a value in Ethereum it can be considered a payment The behavior of such transactions depends on whether the destination address is a contract or an Externally Owned Account EOA For EOA addresses the value you send is added to the recipient s balance If the address is new and hasn t been seen before it will be added to the client s internal representation of the state and its balance will be initialized with the payment value If the destination address is a contract the Ethereum Virtual Machine EVM will execute the contract and attempt to call the function specified in the transaction s data payload If no data is provided the EVM will try to execute a fallback function If the fallback function allows payments it will be executed to determine the next steps If there is no code in the fallback function or if it is not payable the transaction will be reverted A contract can reject incoming payments by throwing an exception when a function is called or based on specific conditions coded in a function If the function executes successfully without exceptions the contract s state will be updated to reflect an increase in its ether balance In simpler terms when you send ether to an individual it increases their balance But if you send ether to a contract the contract s code is executed and if the contract allows payments its balance will increase Contracts can also reject payments based on their code s conditions Transmitting a Data Payload to an EOA or ContractWhen you include data in your transaction it is usually intended for a contract address Sending data to an externally owned account EOA is also valid but its interpretation depends on the wallet you use The Ethereum protocol ignores the data when sent to an EOA and most wallets also ignore any data received by EOAs they control In the future there might be standards that allow wallets to interpret data like contracts do enabling transactions to invoke functions within user wallets However it s important to note that the interpretation of data by an EOA is not governed by Ethereum s consensus rules unlike contract executions Assuming your transaction is targeting a contract address the Ethereum Virtual Machine EVM interprets the data as a contract invocation In most cases the data represents a function call specifying the function s name and any encoded arguments The data payload sent to an ABI compatible contract which most contracts are is a hexadecimal serialization that consists of two parts Function Selector The first bytes of the Keccak hash of the function s prototype This uniquely identifies the function you want to invoke Function Arguments The arguments of the function encoded based on the rules defined in the ABI specification for various data types In simpler terms when you send data to a contract it is treated as a request to call a specific function within that contract and the data payload contains the necessary information to identify the function and pass its arguments Special Transaction Contract CreationWhen you want to create a new contract on the Ethereum blockchain you send a special transaction to an address known as the zero address represented by x in the to field This address is not associated with an externally owned account EOA or an existing contract It serves only as a destination for contract creation While the zero address is specifically meant for contract creation it sometimes receives accidental payments from various addresses This can result in the loss of ether if sent by mistake On the other hand intentional ether burns where ether is deliberately destroyed by sending it to an address that cannot spend it can also occur However if you intend to perform an intentional ether burn it is recommended to use a designated burn address to make your intention clear to the network xdEaDAny ether sent to the designated burn address will become unspendable and be lost forever To create a contract your transaction only needs to include a data payload containing the compiled bytecode that will generate the contract The purpose of this transaction is solely to create the contract Optionally you can specify an ether amount in the value field to set the new contract with an initial balance However sending ether to the contract creation address without a data payload no contract has the same effect as sending it to a burn addressーit will be lost as there is no contract to credit Digital SignaturesIn this section we look at how digital signatures work and how they can be used to present proof of ownership of a private key without revealing that private key The Elliptic Curve Digital Signature Algorithm ECDSA The digital signature algorithm used in Ethereum is called the Elliptic Curve Digital Signature Algorithm ECDSA It relies on private public key pairs based on elliptic curves A digital signature in Ethereum serves three purposes proving authorization ensuring non repudiation and guaranteeing data integrity A digital signature is a mathematical scheme that verifies the authenticity of digital messages or documents It consists of two parts creating the signature using a private key and verifying the signature using a public key Creating a Digital SignatureIn Ethereum when creating a digital signature the transaction is used as the message specifically the Keccak hash of the RLP encoded transaction data The private key of the account is used for signing resulting in the signature The signature is composed of two values often referred to as r and s Sig F sig F keccak m k where k is the signing private key m is the RLP encoded transaction F keccak is the Keccak hash function F sig is the signing algorithm Sig is the resulting signature The function F sig produces a signature Sig that is composed of two values commonly referred to as r and s Sig r s Verifying the SignatureTo verify a signature you need the signature itself represented by r and s the serialized transaction and the public key that corresponds to the private key used to create the signature Verification ensures that only the owner of the private key that generated the public key could have produced the signature for that specific transaction The signature verification algorithm takes the message which is a hash of the transaction the public key of the signer and the signature r and s values If the algorithm determines that the signature is valid for the given message and public key it returns true ECDSA MathThe signature algorithm involves generating a ephemeral temporary private key to ensure the security of the sender s actual private key This temporary key is used to calculate the values r and s in the signature Here s a simplified explanation of the steps involved Generate a random number q as the temporary private key Calculate the corresponding temporary public key Q using the elliptic curve generator point The r value of the signature is the x coordinate of the temporary public key Q Calculate the s value of the signature using the formula s ≡q Keccak m r k mod p where q is the temporary private key r is the x coordinate of the temporary public key k is the actual private key of the sender EOA owner m is the transaction data p is the prime order of the elliptic curve To verify a signature the process is the inverse of the signature generation function It involves using the r and s values of the signature along with the sender s public key to calculate a point on the elliptic curve called Q which represents the ephemeral public key used during signature creation Here are the steps Check that all inputs are properly formatted Calculate the value w by taking the inverse of s modulo p Calculate u as the result of multiplying the Keccak hash of the signed transaction data m by w modulo p Calculate u as the result of multiplying r by w modulo p Finally calculate the point Q on the elliptic curve using the formulaQ ≡u G u K mod p where r and s are the signature values K is the sender s public key EOA owner s public key m is the signed transaction data G is the elliptic curve generator point p is the prime order of the elliptic curve If the x coordinate of the calculated point Q matches the r value of the signature then the verifier can conclude that the signature is valid Separating Signing and Transmission Offline Signing Once a transaction is signed it can be transmitted to the Ethereum network Normally the process of creating signing and broadcasting a transaction happens in a single step However it is possible to separate the signing and transmission steps for security reasons Separating these functions is done to protect the private keys used for signing The computer that signs the transaction needs to have the private keys loaded in memory which can be risky if it is connected to the internet By performing the signing on an offline device and the transmission on an online device known as offline signing the private keys remain secure Here s an overview of the offline signing process Create an unsigned transaction on an online computer where the current account state including the nonce and available funds can be retrieved Transfer the unsigned transaction to an offline device that is not connected to the internet for signing This can be done through methods like using a QR code or a USB flash drive Transmit the signed transaction back to an online device for broadcasting it on the Ethereum blockchain This can be done by scanning a QR code or transferring the transaction via a USB flash drive By following this process the private keys are kept offline during the signing step reducing the risk of unauthorized access to the keys Transaction PropagationThe Ethereum network uses a system where all computers in the network called nodes are connected to each other When someone creates or sends a transaction it spreads across the network like a wave reaching every node Each node checks if the transaction is valid and then passes it on to its connected nodes This process continues until every node has a copy of the transaction The way transactions spread is designed to be fast and efficient It ensures that within a few seconds the transaction is known to every node in the network around the world The best part is that no node can tell where the transaction originated from This makes it difficult for anyone to track or interfere with transactions unless they control a large portion of the network This approach helps maintain security and privacy in the Ethereum network It ensures that transactions are widely distributed and protected from unauthorized access or manipulation Recording on the BlockchainIn the Ethereum network some nodes are operated by miners who use powerful computers to process transactions and add them to blocks These computers known as mining farms work to find a proof of work that validates the transactions in a block Valid transactions are then recorded in the Ethereum blockchain Once a transaction is included in a block and mined it becomes a permanent part of the blockchain It can modify the state of the Ethereum network by changing account balances or invoking contracts that make internal changes These changes are recorded in a transaction receipt which also includes any associated events In simpler terms when a transaction completes its journey from creation to being mined it leaves a lasting impact on the Ethereum network and becomes a permanent part of the blockchain Multiple Signature Multisig TransactionIn Ethereum it is possible to create smart contracts that enforce custom rules for transferring ether and tokens This allows for the implementation of features like multisignature accounts where funds can only be spent when multiple parties sign a transaction To set up a multisignature account you transfer your money to a special contract instead of a regular account This contract is programmed with the rules you want such as requiring two or more people to sign off on transactions When you want to send money from the multisignature account all the authorized users need to sign and approve the transaction using a wallet app These contracts can also be designed to require multiple signatures for executing specific actions or triggering other contracts The security of the multisignature system depends on the code written for the contract While this flexibility is powerful it also introduces the risk of programming errors that could undermine the security of multisignature setups There are proposals to create a built in feature for multisignature transactions in Ethereum to simplify the process and make it more secure similar to Bitcoin s system that is known for its robustness and security ConclusionTransactions serve as the initial step for all actions within the Ethereum system They act as the triggers that prompt the Ethereum Virtual Machine to process contracts update balances and make changes to the Ethereum blockchain s overall state	2023-07-11 10:51:12

海外TECH	DEV Community	Qwik – The Post-Modern Framework	https://dev.to/this-is-learning/qwik-the-post-modern-framework-3c5o	Qwik The Post Modern Framework Qwik introductionModern frameworks face a big challenge of performance they are not on top of what companies are looking for Some of these frameworks have adapted performance as the real utility of them for example Svelte but none of them have reached the real expectations because they are looking to make web apps faster in the run time but no one is looking for the source of the problem Here comes Qwik which adopted a different approach the focus shift from doing faster to doing less It s a key difference that will change the game Ultimately the fastest tool is probably the one doing the least amount of repetitive work Qwik is a framework created by the creator of Angular Misko Hevery with a collaboration of Adam Bradley who created Ionic and Manu Almeida who created Gin Framework These are pioneers of web development I don t think we are dealing with just another javascript framework Maybe we should be prepared for a new framework that will change the paradigm Why Qwik Qwik comes with a clear goal achieving top performance perfection javascript and pure HTML Yes we are here It s time for that Qwik is trying and also succeeding to go beyond what other frameworks can do The last framework that came with a new concept was Astro which introduced partial hydration a revolution in javascript frameworks For example if we have a page that starts with a text that does not need javascript we load nothing but if we scroll down to a component that needs javascript for the interaction we hydrate the page with the needed javascript Qwik killed the game with no partial hydration but zero hydration and javascript on the first load For instance if we have a form contact at the bottom of a page Angular React or VueJS will load the javascript needed on the first load Astro will load it if we scroll down Qwik will load it only and only if we click on the send button of the form it loads javascript not when we have the form in front of us but if we interact with it ‍ Qwik key conceptQwik the HTML first framework s philosophy is clear make the fastest possible time to interactive to do it faster by doing nothing The framework delays the invocation of the javascript as much as possible and invokes it only what is absolutely needed The focus is on the first load As such it only loads pure HTML To achieve this Qwik is based on an important concept In this paragraph we will dive deep into it ResumabilityThe modern frameworks now compete to improve hydration Qwik is unique in that it has resumability The name of the concept gives us a perception of what we are talking about “stop resume resume the application where the server left off in place of replaying all of the work Serializing event handlers is the key to stopping and resuming the application But doing this is not something new we did it before through jQuery For example using pure javascript The difference with Qwik is that working on Qwik is like working on React it has adopted the modern DX If we try to think deeply about the figure above we will understand the reel problem scaling If we have an extensive web application it will take a lot of time to load with hydration Even with Partial Hydration it will be challenging to scale Qwik with the resumability only loads HTML which does not take a lot of time It s a fraction of a second and you have your application loaded in your browser Qwik CityOn the st of May Hevery said in a podcast that their goal is building a router that offers the capability of doing MPA multiple page application routing with the benefits of SPA Single page application routing In other words doing MPA rooting without refreshing the page Only render the parts that need refreshing That may sound like fiction but it s already done they did it and its name is Qwik City So Qwik is a mix of server side rendering and client side rendering It takes advantage of the two of them Qwik City is the meta framework designed for Qwik like Next js for React js The routing in Qwik City is so simple it s based on the structure of our directories in the routes directories src └ーroutes └ーsome └ーpath └ーindex tsx lt With our javascript meta framework the application is loaded without a single javascript dedicated to Qwik city but there is more than that It also offers Directory based routingNested layoutsFile based menusBreadcrumbsSupport authoring content with tsx or mdx file formatsData endpoints ConclusionModern frameworks download all the javascript and after that they execute all of it Qwik downloads a little bit of javascript and it doesn t execute it until we need it The framework is changing the mental model We think that Qwik will be one of the pioneers in the JS frameworks It has improved startup performance which is a real problem of modern frameworks but with Qwik it s not the case Let us see the future and stay tuned because this is our first article about the framework and of course it s not the last In the coming articles we will dive deep into the core

海外TECH	DEV Community	Creating an Easter Egg with the Konami Code in Svelte	https://dev.to/pbouillon/creating-an-easter-egg-with-the-konami-code-in-svelte-42p1	Creating an Easter Egg with the Konami Code in SvelteThe Konami Code is a originally a cheat code that now belongs to the pop culture It s a fairly traditional code that consists of the following key sequence ↑ ↑ ↓ ↓ ← → ← → B AInitially used in many Konami Games it then spreads to other video games and even in other software and websites such as in one of the Bank of Canada s website Since it has spread so far into the geek culture why not incorporating it into your next website In today s article we are going to see how to detect the Konami Code in Svelte by leveraging the concept of stores in order to create a small easter egg Table of ContentsReferencing the Konami CodeDetecting the Last Pressed KeysDetecting the Konami CodeReacting to Its Detection Referencing the Konami CodeThe Konami Code will be a sequence of keys that can either be Arrow UpArrow DownArrow LeftArrow Righta in lowercase or uppercaseb in lowercase or uppercaseFrom that point we can create a custom type to work with type KeyCode ArrowUp ArrowDown ArrowLeft ArrowRight KeyB KeyA undefined Other keys are to be ignoredWe can then represent the Konami Code as a sequence of KeyCodes const konamiCode KeyCode ArrowUp ArrowUp ArrowDown ArrowDown ArrowLeft ArrowRight ArrowLeft ArrowRight KeyB KeyA Detecting the Last Pressed Keys Creating a readable storeThe last pressed keys sequence will be store that can only be modified when a key is pressed not from the outside For that Svelte has the notion of readable store In our case we want the store to listen to any key down event when first subscribed and to remove this listener when unsubscribed const lastKeyPressed readable new Array lt KeyCode gt gt const handleKeyDown event KeyboardEvent void gt window addEventListener keydown handleKeyDown return gt window removeEventListener keydown handleKeyDown And just like that we created a store that will hold a sequence of KeyCode or undefined if a pressed key does not belong to the Konami Code Implementing the handleKeyDown functionNow that we have our container we still have to implement the logic that will be executed on each key pressed What we would ideally like is to map a pressed key to a KeyCode and append it to the sequence We can start by creating a map that will convert a the KeyboardEvent key property to a KeyCode const keyMap Record lt string KeyCode gt ArrowUp ArrowUp ArrowDown ArrowDown ArrowLeft ArrowLeft ArrowRight ArrowRight a KeyA b KeyB A KeyA B KeyB What is left is to use it to detect which KeyCode has been pressed const lastKeyPressed readable new Array lt KeyCode gt gt const handleKeyDown event KeyboardEvent void gt const keyPressed keyMap event key window addEventListener keydown handleKeyDown return gt window removeEventListener keydown handleKeyDown However we might have the key but we do not have any way to access the current value held by the store For that the function used in readable takes two additional parameters A set function that can be used to set the value of the storeAn update function that uses a callback to modify the current value of the storeWhile set would not help in appending a value update definitely will let s grab it const lastKeyPressed readable new Array lt KeyCode gt set update gt const handleKeyDown event KeyboardEvent void gt const keyPressed keyMap event key update currentSequence KeyCode gt const next currentSequence concat keyPressed Discards the oldest value if the sequence is too long if next length gt konamiCode length next splice return next window addEventListener keydown handleKeyDown return gt window removeEventListener keydown handleKeyDown We now have a store that is storing the latest pressed keys and exposes them as sequence of the Konami Code Now onward to detecting it Detecting the Konami CodeWe have several ways of signaling to a consumer when the Konami Code has been entered However as I m thinking of stores as a kind of RxJS s Observables I tend to prefer deriving a value from it to keep my code as declarative as possible If the concept of declarative code is not something you are familiar with Joshua Morony has some wonderful videos on that subject Hopefully it seems to also be the case for the Svelte core dev team as it is possible to derive a store from another one by using derived To derive a store the syntax is pretty straightforward As a first parameter the derived function is expecting the store to derive its value fromAs a second parameter we should define a function that takes the value emitted by the store we derived from and infer the value of the current storeIn our case the inferred value will simply be a boolean evaluated to true if the current sequence matches the Konami Code Don t forget to export this store export const isKonamiCodePressed Readable lt boolean gt derived lastKeyPressed pressedKeys KeyCode gt JSON stringify pressedKeys JSON stringify konamiCode We could have computed the value of JSON stringify konamiCode instead of recomputing it everytime but for the sake of this tutorial I will spare you some additional code Reacting to Its DetectionWith our Konami Code detection store we can now use it in our Svelte app to add a small easter egg In a new Svelte component all we have to do is to subscribe to the store and react to whenever it has been entered lt script lang ts gt import onDestroy onMount from svelte import type Unsubscriber from svelte store import isKonamiCodePressed from lib stores konami let unsubscribe Unsubscriber gt onMount gt unsubscribe isKonamiCodePressed subscribe isKonamiCodePressed boolean void gt if isKonamiCodePressed return console log Konami Code detected Don t forget to remove the event listener onDestroy unsubscribe lt script gt While it works a console log might not be the most funny thing we can do with that Let s build something visual and unexpected like confetti Grab JS Confetti npm i js confettiAnd replace the former code with the following one lt script lang ts gt import onDestroy onMount from svelte import type Unsubscriber from svelte store import JSConfetti from js confetti import isKonamiCodePressed from lib stores konami let unsubscribe Unsubscriber gt onMount gt const jsConfetti new JSConfetti unsubscribe isKonamiCodePressed subscribe isKonamiCodePressed boolean void gt if isKonamiCodePressed return jsConfetti addConfetti onDestroy unsubscribe lt script gt You can now use this component on whatever page you want the user to be able to enter the Konami Code Wanna see a live example Try it out on my landing

海外TECH	Engadget	The best Amazon Prime Day headphone deals for 2023	https://www.engadget.com/best-amazon-prime-day-headphone-deals-163351574.html?src=rss	The best Amazon Prime Day headphone deals for Amazon Prime Day has brought several headphones and earbuds we recommend down to or at least close to the lowest prices we ve tracked If you ve been looking to grab a new pair now s a great time to doso since Prime Day is typically only matched by Black Friday when it comes to sales on the latest headphones We ve rounded up the best Prime Day headphone deals we can find covering models from Sony Bose Apple Beats and several others Sony WH XMThe Sony WH XM is down to for Prime Day which is a new all time low and off the noise canceling pair s list price It s part of a larger Sony headphones sale that includes a number of solid models The XM is the top pick in our guide to the best wireless headphones We gave it a review score of last year praising its comfortable fit effective active noise cancellation ANC crisp call quality and ish hours of battery life By default they have a bass forward sound that s best suited for hip hop and EDM but you can customize the EQ through Sony s companion app Like many Sony headphones they also come with a range of useful bonus features such as Speak to Chat which automatically pauses whatever you re playing when the microphones detect you are speaking Sony WH XMThe XM s predecessor the Sony WH XM is also on sale for That isn t an all time low but it s off the pair s MSRP and nbsp below its typical sale price Though we rate the XM higher the XM still delivers powerful ANC hours of battery life and a similar feature set It can fold up unlike its successor and its headband has more plush padding Some may also prefer to avoid the XM s adaptive ANC system which adjusts automatically based on your environment However XM isn t quite as adept at muting mid and high frequency noises it sounds a little boomier out of the box and it doesn t feel as light on the head Its call quality is worse too But for less than it s still a great buy Bose QuietComfort If you want a premium set of noise canceling headphones for less than the Bose QuietComfort is another strong value at its Prime Day price of That s tied for an all time low and roughly below the pair s average street price We gave the QC a review score of in and call it a worthy alternative in our buying guide It isn t as fully featured as the XM and only lasts around hours per charge but it has a more neutral sound by default still powerful ANC and a design that s about as comfy yet doesn t sacrifice the ability to fold up They also use physical buttons instead of touch controls Bose QuietComfort Earbuds IIThe Bose QuietComfort Earbuds II are on sale for which is more than its all time low but still about off its average street price This is the “best noise cancellation pick in our guide to the best wireless earbuds and it earned a review score of last year Its ANC is among the strongest we ve heard on any headphone let alone a true wireless pair It s adept across low mid and treble range frequencies so it can mute nearby voices plane engines or the hum of an air conditioner with similar success This pair is on the bulky side however and its lack of wireless charging and multipoint connectivity is disappointing at this price It did gain single bud support earlier this year though Anker Soundcore Space AThe Soundcore Space A was already our favorite pair of wireless earbuds for those on a budget and now it s even more affordable at That s below its usual going rate The Space A provides the kind of performance and features you d expect from true wireless earbuds that cost twice as much strong ANC a small and light design a warm sound that s enjoyable out of the box but customizable through a companion app a transparency mode wireless charging solid battery life around eight hours per charge and the ability to connect to two devices at once It can t auto pause music when you remove an earbud nor can it fully match the best premium pairs when it comes to ANC strength sound quality or mic clarity But it s not far off and it s way easier on the wallet Apple AirPods ProThe Apple AirPods Pro are available for which is a deal we ve seen for most of the last few months but still less than Apple s list price This set continues to be an excellent option for iPhone owners as it connects easily with other Apple devices bakes its controls directly into iOS supports Find My tracking and lets you access Siri hands free Its ANC isn t as broadly powerful as the QuietComfort Earbuds II but it s good and its transparency mode is among the clearest we ve heard While you can t manually customize the AirPods Pro s sound it s pleasingly warm by default That said the six hour battery life is just OK the control scheme takes some getting used to and you really need to be committed to the Apple ecosystem to get the most out of it We gave the Pro a score of last year and call it the “best for iOS pick in our wireless earbuds guide Amazon Echo Buds The latest Amazon Echo Buds are down to nbsp for Prime members which is a discount and an all time low We recommend this pair in our budget wireless earbuds guide to those who prefer an open design instead of one that fully inserts into the ear canal Its audio quality is solid for the price and form factor and it supports features we don t often see in this range including auto pausing multipoint and EQ customization It s not sweat resistant enough for the gym but the design rests lightly in the ear Naturally it also has Alexa baked in Don t expect super rich sound or more than five hours of battery life but if you can t stand the feeling of in ear headphones the Echo Buds are a decent option at this price Apple AirPods rd gen The third gen Apple AirPods are on sale for tying its all time low Apple sells these earbuds for though we often see them for less on Amazon It s another open back pair but its balanced sound is a noticeable step up from the Echo Buds with more bass depth than usual for unsealed earbuds albeit not a ton There s no ANC as expected but you still get wireless charging button like touch controls and a host of Apple friendly features Just note that the earpieces are a little large so they may not fit well with certain ear shapes We gave the third gen AirPods a review score of in late Apple AirPods nd gen The second gen AirPods meanwhile are available for That s off its typical street price It s hard to call this a great value in Its five hour battery life is worse than the third gen AirPods the one size fits all design can be finicky and you can get better sound for much less But if you re an iPhone user who wants the usual AirPods suite of software perks in an unsealed design this older model may still work The third gen set gives a big upgrade in audio quality but the thinner earpieces here may fit some better Bowers amp Wilkins Px SThe Bowers amp Wilkins Px S are down to a drop that matches the best price we ve tracked This is the runner up pick in our wireless headphones guide and we gave it a score of last year It s worth considering over the WH XM if you re willing to trade ANC strength for a more luxurious design The hyped up sound should particularly appeal to bass lovers the battery lasts more than hours per charge and while the ANC can t touch the best from Sony and Bose it s still useful The XM offers better call quality and a wider range of software features though including a more extensive custom EQ tool Audio Technica ATH MxBTAudio Technica s ATH MxBT are on sale for which is a discount and a new low This is the budget pick in our wireless headphones guide delivering a light fit impressive battery life rated at hours per charge multipoint connectivity and good enough sound for the money It has few bonus features and its build quality isn t exactly refined but the MxBT should fit the bill if you just want a no frills wireless headphone on the cheap Anker Soundcore Life QIf you re on a budget but don t want to give up ANC Anker s Soundcore Life Q is another pair of wallet friendly over ears we like It s down to which isn t the best price we ve seen but a discount all the same The Q s ample padding to hours of battery life and multi device pairing are nice and though its ANC certainly isn t top tier it s beyond adequate at this price Audio quality isn t as nice as the MxBT out of the box as it massively inflates the bass but you can rein it in somewhat through the Soundcore app That said the sound gets worse when ANC is off and the plastic design is a little flimsy A couple of similar Soundcore headphones are also on sale for Prime Day with the Soundcore Life Q down to and the Soundcore Space Q down to an all time low of The former is off its average street price while the latter is a roughly discount The Q is a modest upgrade that improves call quality and adds support for the LDAC audio codec The Q feels sturdier than either pair improves the ANC and isn t quite as bass heavy by default It also uses an adaptive ANC system The Q is the best of the three for those willing to pay for it though it trails the pricier options above and the Q is the better bargain for those looking to spend as little as possible EarFun Air Pro You can grab the EarFun Air Pro for when you use the code EAPANC at checkout That s below its typical price The Air Pro is the runner up pick in our guide to the best budget wireless earbuds It has a similar feature set to the Space A but its battery life and ANC are slightly worse and it s a little more amped in the bass and treble by default Its mic quality and IPX rated water resistance are upgrades however so if you want to save a few bucks or just prefer an AirPods style “stem design it s a fine choice EarFun Free SThe EarFun Free S meanwhile are down to with the checkout code FREESPD which is a drop We list the Free S as the “under pick in our budget earbuds guide It s another one that s heavy on the bass but it s a better example of a “fun sound signature than most in its price range and it s comfortable to wear for hours at a time It s also fully waterproof It lacks features like ANC wear detection multi device pairing or a transparency mode but for less than its shortcomings are easier to accept JLab Go Air PopIf you want a pair of competent wireless earbuds for the lowest amount possible consider the JLab Go Air Pop Right now it s available for which is a few bucks higher than its all time low but below its usual street price in recent months We highlight the Go Air Pop in our budget wireless earbuds guide For less than a Jackson it provides a compact design eight ish hours of battery IPX water resistance and a full set of functional touch controls While there s no app JLab bakes three EQ presets into the earbuds themselves The boomy sound is worse than the EarFun Free S but this is a set of earbuds that aren t awful As a backup for your main pair you could do much worse Beats Studio Buds Prime Day has brought the first discount on the Beats Studio Buds as the recently released pair is off at We gave these earbuds a review score of in May praising their improved sound ANC and call quality compared to the original Studio Buds Like that pair they re tiny and comfortable but they don t use an Apple H or H chip so they lack certain AirPods style tricks such as automatic device switching and audio sharing Others like fast pairing Find My tracking and hands free Siri are still available though and Beats supports similar features on Android To be clear the Studio Buds s ANC battery life and audio quality slot behind the top picks in our buying guide and their lack of auto pausing and wireless charging is hard to swallow But if you want a set of Apple earbuds that cost less than the AirPods Pro they should have appeal For a cheaper alternative the base Studio Buds are on sale for They aren t a better buy than the Space A but if you like the Studio Buds aesthetic they re still decent We ll also mention the Beats Fit Pro that one isn t significantly discounted for Prime Day but it s our favorite true wireless pair for workouts and does utilize Apple s H chip Sony LinkBuds SThe Sony LinkBuds S are on sale for which matches their all time low and sits about below its average street price This is an honorable mention in our wireless earbuds guide as it delivers a small design that s easy to wear over time decent ANC and sound quality for the price and like other Sony headphones a useful suite of bonus features The top pick in our guide Sony s WF XM is down to but we re hesitant to call it a good deal The earbuds themselves are great with better battery life audio quality and ANC than the LinkBuds S albeit in a larger frame But severalrecentreports suggest that Sony will launch a follow up in the near future Most people should hold off on the current model for now especially since we ve seen this deal price for much of the last few months Google Pixel Buds ProThe Google Pixel Buds Pro is down to which is within of the earbuds all time low and roughly off their typical going rate This is the “best for Android pick in our buying guide since it offers AirPods style integration with Google s OS and Pixel phones in particular Its ANC and punchy V shaped sound profile are pleasing though not superlative and it can get a good ish hours of battery life with ANC off or a decent seven hours with it on Its call quality and transparency mode are mediocre however and the fit may be tricky for those with smaller ears Still this a decent mid range option when it s discounted to this extent We gave the Pixel Buds Pro a score of last year Your

海外TECH	Engadget	The best Amazon Prime Day TV deals for 2023	https://www.engadget.com/best-amazon-prime-day-tv-deals-100719094.html?src=rss	The best Amazon Prime Day TV deals for Amazon Prime Day has begun and it s brought a number of TV discounts along with it If you ve been looking to pick up a new set we ve rounded up the best Prime Day TV deals we could find below While we don t formally review TVs at Engadget we ve pored over reviews from users and other sites we trust to ensure you don t waste your money The TV market itself is in a bit of a transition period so be aware that many of our picks are models that are close enough to their successors but cost much less And if you don t need a new TV we ve also included a few Prime Day deals on media streamers Samsung SBThe inch Samsung SB is on sale for matching its all time low Typically this highly rated set has cost an extra to in recent months The SB s QD OLED panel combines OLED tech with a quantum dot layer allowing it to deliver high contrast and wide viewing angles without sacrificing as much as typical OLED TVs in terms of brightness and color saturation This means it should provide a rich image even in brighter rooms It can also play up to K Hz which is handy for the PS or Xbox Series X but like all Samsung TVs it doesn t support Dolby Vision HDR The SB is a model so it s on the way out in favor of the new SC The latter supports a faster Hz refresh rate and runs its ports through an external box which makes the design thinner Other reviewerssay it can get a bit brighter too But the S currently costs and for a and inch model respectively and its upgrades don t appear to be massive enough to justify that extra cost for most If you re in the market for a premium TV the SB should remain the better value while it s still available LG CFor a relatively more affordable OLED TV the inch LG C is down to while the inch model is available for Neither offer is an all time low but they re each about below their respective street prices The C can t match the brightness and color range of a QD OLED set like the Samsung SB but it still offers excellent contrast deep black levels and wide viewing angles It has four HDMI ports that can play K at Hz it supports gaming friendly features like VRR and ALLM and it comes in a wider range of sizes than the SB It works with all the major HDR formats too Dolby Vision included It s just less ideal in a brightly lit room nbsp LG has rolled out a new C model for but it s pricier and manyreviewssuggest it s only a marginal upgrade outside of adding support for DTS audio Sony AKIf the LG C goes out of stock the Sony AK is another commendable OLED TV It s down to for a inch model and for a inch model Both deals mark new lows The former is about off its recent street price while the latter is a roughly discount The C is broadly considered a better option thanks to its superior brightness levels and two extra HDMI ports but the AK still gets you the core benefits of an OLED display It also runs on Google TV which some may prefer to LG s webOS platform Like the C you ll get the most out of it if you stay away from glare nbsp Sony s follow up the AL should be a better buy when prices come down but right now it starts at At that price most should be better off with the Samsung SB Samsung QNBThe Samsung QNB is back down to for a inch model If you re looking for a smaller set the inch version is on sale for as well The QNB is an LCD TV so it can t supply the near perfect blacks and super wide viewing angles of an OLED panel but it can get significantly brighter and reviewssayitprovides better contrast than most non OLED TVs thanks to its Mini LED backlight There s still no Dolby Vision but it gives you four full HDMI ports K Hz support and multiple types of VRR If you want a high end TV for a room plagued by glare it s a good buy The new QNC is out but costs much more so again last year s set is still the better buy for now If you opt for the inch model note that it has worse viewing angles than the larger variants but also supports a faster Hz refresh rate That feature should be useful if you want a TV that can double as a gaming PC monitor Samsung The Frame TVSamsung s inch The Frame TV is down to which is a new low and about off its typical street price The Frame is a TV for those willing to trade some picture quality for classy aesthetics as it s designed to look like a piece of art you can mount against a wall When you aren t watching something you can use it to display artwork and photos A few pieces come included while others are sold with a subscription The Frame s QLED panel lacks local dimming so its contrast and HDR performance can t really compete with the best options in its price range It only has one HDMI port too But the image is still far from poor and its design does well to blend into a wall as we ve professed before Hisense UHFor those on a tighter budget the inch Hisense UH is a strong value at That s only or so less than the price we ve seen for most of the last few months but it ties the TV s all time low For the money the UH s Mini LED backlight quantum dots and full array local dimming deliver impressive contrast brightness and black uniformity It supports both Dolby Vision and HDR and its two HDMI ports can play K content at a smooth Hz It s still a step down from the premium TVs above particularly when it comes to viewing angles But at this price it s hard to top and it should work in bright or dark rooms The just released Hisense UK meanwhile promises a Hz refresh rate and more local dimming zones but it currently starts at and we can t say how much of an upgrade it is in practice just yet TCL Series RTCL s Series TV is down to for a inch model which is off its usual rate This is a close competitor to the Hisense UH Its contrast and peak brightness aren t as strong according to reviewsaround the web but it still performs well for the price and it might be worth a look if you prefer Roku OS to the UH s Google TV platform Several of TCL s TVs are down to new lows as well including the inch Q for the inch Q for and inch flagship QM for None of these are really a one to one replacement for the Series though The Q is the closest but it lacks the Series TV s Mini LED backlight The QM does have Mini LED tech but it s priced to compete with OLED and higher end LCD sets We ve yet to test the new TCL TVs and reviews elsewhere are sparse so consider this a PSA more than a full recommendation Hisense AHThe Hisense AH is down to for a inch model and for a inch set Both deals match all time lows The AH is very much an entry level K TV so don t expect especially high contrast or rich colors compared to pricier options There s no local dimming and it s limited to a Hz refresh rate But for this price its picture is perfectly fine The inch model s VA panel should be particularly decent in a dark room though it ll have narrower viewing angles than the inch set s IPS display And while it can be sluggish to navigate apps its Google TV interface makes it easy to find things to watch None of this will blow you away but as a cheap secondary TV the AH should do the job If you re looking for a middle ground between the AH and UH consider the Hisense UK It costs for a inch model and offers Mini LED backlighting which is rare for the cost Recentreviews say it delivers better contrast control and color volume than most TVs in its price range as a result though it s still limited to Hz and doesn t have the widest viewing angles It s not priced any lower than usual for Prime Day either Amazon Fire TV Omni QLED SeriesAmazon s Fire TV Omni QLED Series is on sale in several sizes for Prime Day with the and inch models down to and respectively Those match the best prices to date for the and inch sets the other two are more than their previous lows You d get the Omni QLED if you re especially fond of Amazon s Fire OS as its useful voice remote hands free Alexa support and tight integration with Amazon services are like having a Fire TV Cube baked into the TV You can turn off the mics with a built in switch Its picture quality isn t bad either but reviews say its brightness lags behind competing models from Hisense and TCL Roku Streaming Stick KThe Roku Streaming Stick K is the top pick in our guide to the best media streamers and right now it s available for While that s more than the lowest price we ve tracked it s below Roku s list price and less than the typical sale price we ve seen this year The Streaming Stick K supports all the major apps and HDR standards including Dolby Vision HDR HDR and HLG Its compact design plugs directly into an HDMI port while its remote has volume and power controls for your TV The whole thing is quick to load apps and for those with Apple devices it also supports AirPlay While Roku s OS is blander than rivals from Google and Amazon its grid style UI is dead simple to navigate and its search function does well to present shows from across streaming services Note that Roku also sells the Streaming Stick K which has an upgraded voice remote with a rechargeable battery a lost remote finder and a headphone jack for private listening The Streaming Stick K can also do private listening but only through the Roku mobile app The Plus model is better if you can afford it but it s not on sale as of this writing Roku Express K If you want a more affordable K Roku streamer the Roku Express K is worth considering at its Prime Day price of While that s not an all time low it s off Roku s MSRP The Express K offers the same general experience as the Streaming Stick K but it can t plug directly into a TV it doesn t support Dolby Vision and it has slightly slower WiFi so it may have more trouble if your internet is particularly finicky The Streaming Stick K is the safer buy when both devices are on sale but if you really want to save this is a fine value Google Chromecast with Google TV K The Google Chromecast with Google TV is down to which is a deal we ve seen several times before but still comes in below its list price This is the runner up pick in our buying guide It s getting a bit long in the tooth but it s worth grabbing over a Roku streamer if you want a device that s more proactive about recommending shows you might like based on your viewing history Compared to Roku OS Google TV is centered more on content than apps though it s still easy to reach the latter and it s more nuanced when it comes to voice controls and searching for content Naturally it also works better with Google services like YouTube TV though it doesn t support AirPlay or Apple TV Google makes an HD version of the Chromecast that outputs in p but otherwise works like the K model It s not on sale now but it s a good choice if you like the Google TV experience and want to add streaming functionality to an older or smaller set Amazon Fire TV Stick K MaxThe Fire TV Stick K Max is on sale for which is below its list price and lower than the usual sale price we ve seen This is Amazon s fastest streaming stick and its remote comes with Alexa baked in It supports Dolby Vision HDR HDR and HLG and like the rest of the Fire TV lineup it has just about all of the necessary streaming apps Unlike the standard Fire TV Stick K it includes a WiFi radio though you ll need a compatible router and an unusually fast internet connection to see any advantage from that We generally prefer Roku s and Google s interfaces over Amazon s Fire TV OS which more aggressively displays ads on its home screen and prioritizes Amazon s content throughout the UI It lacks AirPlay support as well But these issues might be easier to look past if you often use Alexa and Prime Video especially when the upfront cost is this low Amazon Fire TV Stick and Fire TV Stick LiteThe standard Fire TV Stick and Fire TV Stick Lite are best used with older TVs as they each top out at a p resolution instead of K Both lack Dolby Vision HDR though they retain HDR HDR and HLG and can be more sluggish than the K Max when switching between apps as well That said the rest of the experience is similar The main difference is that the base Fire TV Stick s voice remote has app shortcuts and TV controls for volume and power while the Fire TV Stick Lite s remote does not Most people who really want a Fire TV streamer should just get the K Max but if you want to upgrade an office or bedroom TV on the cheap the Fire TV Stick is down to while the Fire TV Stick Lite is down to Both deals represent all time lows NVIDIA Shield TV ProThe NVIDIA Shield TV Pro is available for this Prime Day a drop that matches the set top box s all time low This is the most niche player we recommend in our guide as it released in still costs a ton and uses Android TV instead of the newer Google TV platform found on the Chromecast We highlight it for gaming specifically as its still speedy Tegra X chip plays well with NVIDIA s GeForce Now game streaming service and various Android games If you re looking to run a Plex media server or emulate older games it makes sense there as well The box itself is loaded with ports and it uses upscaling technology to make p content look crisper on K TVs It s hard to call the Shield TV Pro a great value at this price in but if you re an enthusiast who has had their eye out for a sale this is a chance to save at least a little bit Your Prime Day Shopping Guide See all of our Prime Day coverage Shop the best Prime Day deals on Yahoo

Video is now on par with rivals with K at up to p with bit quality Autofocus is incredible for both video and stills and the in body stabilization does a good job The biggest drawbacks are rolling shutter that limits the use of the electronic shutter and the relatively high price ーbut the discount helps ease the latter a bit The sale is on now but extends to July th nbsp Sony A IIIWhen it first came out I said that Sony s megapixel A III was a near perfect all around camera That still applies The already excellent point hybrid phase detect autofocus system has been updated via firmware with the real time eye and animal AF features introduced with the A A models On top of that you can shoot bursts at up to fps with continuous autofocus and auto exposure On the video side however it s been
