海外TECH	DEV Community	ExpiringLRUCache and The CLOCK Algorithm: A Fun Dive into Python Caching	https://dev.to/sbalasa/expiringlrucache-and-the-clock-algorithm-a-fun-dive-into-python-caching-5195	ExpiringLRUCache and The CLOCK Algorithm A Fun Dive into Python Caching IntroductionCaching is a common technique that programs use to speed up access to slow data sources by keeping a copy of the data in fast access memory In Python we can implement this concept in many ways but let s talk about an exciting one The ExpiringLRUCache What is ExpiringLRUCache ExpiringLRUCache is a cache implementation that combines two powerful concepts The Least Recently Used LRU cache eviction policy and an expiration time for cache entries In simple terms it remembers the most recently used items up to a specified limit and for a particular duration After the duration expires or when the cache is full it starts removing items making room for the new ones Sounds cool right The CLOCK AlgorithmBut how does ExpiringLRUCache decide which item to remove first Here comes the CLOCK algorithm It s a smart approximation of the LRU policy Imagine a clock hand moving over each cache item If the item is recently used it gets a second chance and the hand moves on If not it s time to say goodbye to that item How Can We Use ExpiringLRUCache Now let s get our hands dirty with a fun example from expiringlrucache import ExpiringLRUCache Create a cache of size with items expiring after secondscache ExpiringLRUCache Put some items in the cachecache put apple delicious cache put banana yummy cache put cherry tasty Get an item from the cacheprint cache get banana Output yummy After seconds print cache get apple Output None as it s expired With just a few lines of code we ve implemented a speedy cache How to Improve It Though ExpiringLRUCache is quite efficient there are a few ways to boost its performance Eviction Policy For more precise LRU behavior consider implementing a true LRU cache Parallelism If you have a high degree of parallelism consider partitioning the cache into multiple segments each with its own lock Cache Size Tuning Adjust the cache size based on its observed hit rate Dynamic Expiration Strategy Assign longer expiration times to entries that are accessed more frequently Remember it s all about finding the right balance based on your specific needs ConclusionCaching is a powerful tool and with Python s flexibility we can customize it to our heart s content ExpiringLRUCache and the CLOCK algorithm offer an efficient approach to caching making our applications faster and more efficient So next time you find your program waiting for data consider using an ExpiringLRUCache It might just save your day Happy caching	2023-07-24 18:36:41

React	https://dev.to/gustavospriebe/compreendendo-como-os-manipuladores-de-eventos-funcionam-no-react-5eh6	Compreendendo como os Manipuladores de Eventos funcionam no ReactO React sendo uma biblioteca popular e poderosa de JavaScript para construção de interfaces de usuário oferece uma ampla gama de manipuladores de eventos incorporados que facilitam o tratamento de interações do usuário Um manipulador de evento permite que os desenvolvedores anexem uma função que éexecutada em resposta a um evento sendo acionado como clicar em um botão passar o mouse sobre um elemento digitar em um campo de entrada ou redimensionar a janela Neste artigo abordaremos três etapas fundamentais do tratamento de eventos event handling no React que são cruciais para gerenciar efetivamente eventos em suas aplicações definir a função do manipulador vincular eventos aos elementos e acionar os eventos Ao final deste artigo vocêteráuma compreensão sobre a manipulação de eventos no React incluindo os diversos tipos de eventos existentes Etapas do Tratamento de EventosPara lidar efetivamente com eventos no React os desenvolvedores precisam compreender três etapas fundamentais Vamos explorar cada uma delas em detalhes Definindo a Função do Manipulador Em um componente React os manipuladores de eventos são simplesmente funções que definem como o componente deve responder a eventos específicos Para seguir uma convenção de nomenclatura padrão écomum prefixar as funções de manipulador de eventos com handle seguido pelo nome do evento Por exemplo se vocêdeseja tratar um evento de clique a função pode ser chamada handleClick e para tratar mudanças em campos de entrada a função pode ser chamada handleInputChange Vinculando Eventos Para usar um manipulador de eventos énecessário vinculá lo ao elemento correspondente usando o atributo de evento apropriado No React os atributos de eventos são nomeados seguindo a convenção camelCase em vez de minúsculas como éusado no HTML regular Por exemplo em vez de usar onchange vocêusaria onChange no React para vincular o manipulador de evento de mudança Esse processo de vinculação conecta a função do manipulador de eventos ao evento específico ao qual deve responder Acionando o Evento Uma vez que um evento éacionado o React invoca a função do manipulador de eventos correspondente Dentro do manipulador de eventos vocêtem acesso ao objeto de evento permitindo que vocêcolete dados sobre o evento e execute ações com base nesses dados Por exemplo em um evento onChange para um campo de entrada vocêpode obter o valor atual do campo e atualizar o estado do componente de acordo Da mesma forma em um evento onClick vocêpode alternar um estado ou acionar outras ações relevantes Exemplo de tratamento de evento de clique no React import useState from react const EventHandleExample gt const count setCount useState Definindo a Função do Manipulador const handleClick gt setCount count gt count return lt div gt Vinculando e Acionando o Evento lt button onClick handleClick gt Clique em Mim lt button gt lt p gt Clicado count vezes lt p gt lt div gt Neste exemplo quando o botão Clique em Mim éclicado a função handleClick éexecutada atualizando o estado count e re renderizando o componente para exibir a contagem atualizada Tipos de Eventos Tratados pelo ReactAlém das etapas fundamentais do tratamento de eventos o React oferece vários manipuladores de eventos para lidar com diferentes tipos de interações do usuário Vamos explorar alguns dos tipos comuns de eventos que podem ser tratados pelo React Eventos de Clique O evento onClick éum dos manipuladores de eventos mais frequentemente usados no React Ele permite que vocêresponda aos cliques do usuário em elementos como botões links ou imagens Eventos de Mudança O evento onChange éusado para tratar mudanças em elementos de formulário como campos de entrada caixas de seleção e botões de rádio Ele permite que vocêcapture a entrada do usuário e responda às mudanças em tempo real Eventos de Passe do Mouse O React suporta eventos onMouseOver e onMouseOut para lidar com interações de passagem do mouse Esses eventos são frequentemente usados para exibir dicas mostrar informações adicionais ou acionar animações Eventos de Teclado O React fornece manipuladores de eventos como onKeyDown onKeyPress e onKeyUp para lidar com interações de teclado Esses eventos são essenciais para capturar a entrada do teclado do usuário e implementar atalhos de teclado Eventos de Envio de Formulário O React suporta o evento onSubmit para tratar o envio de formulários Ele permite que vocêcontrole o envio do formulário e faça validações antes de enviar os dados para o servidor Eventos de Toque O React também oferece manipuladores de eventos de toque como onTouchStart onTouchMove onTouchEnd e outros permitindo que os desenvolvedores criem aplicativos da web compatíveis com dispositivos móveis Eventos de Foco O React fornece manipuladores de eventos como onFocus e onBlur para lidar com interações de foco Esses eventos são acionados quando um elemento ganha ou perde o foco permitindo que os desenvolvedores controlem o comportamento de foco do usuário Eventos de Rolagem O React suporta o evento onScroll que éacionado quando um elemento érolado Esse evento permite que os desenvolvedores criem animações com base na rolagem e implementem um comportamento de rolagem personalizado Eventos de Arrastar e Soltar O React oferece um conjunto de manipuladores de eventos para lidar com interações de arrastar e soltar Isso inclui onDragStart onDrag onDragEnter onDragLeave onDragOver e onDrop Esses eventos permitem que os desenvolvedores criem funcionalidades de arrastar e soltar em suas aplicações ConclusãoOs manipuladores de eventos incorporados do React permitem que os desenvolvedores criem aplicativos React altamente interativos e responsivos Compreender a variedade de tipos de eventos e seus manipuladores correspondentes capacita os desenvolvedores a construir facilmente uma ampla gama de interações do usuário em seus projetos Ao dominar o tratamento de eventos no React os desenvolvedores podem elevar a experiência geral do usuário e criar aplicações web envolventes	2023-07-24 18:16:40

海外TECH	Engadget	The best midrange smartphones for 2023	https://www.engadget.com/the-engadget-guide-to-the-best-midrange-smartphones-120050366.html?src=rss	The best midrange smartphones for As one of Engadget s resident mobile geeks I ve reviewed dozens of midrange phones and have found that a great smartphone doesn t have to cost a fortune Years of commoditization have brought features once exclusive to high end devices including big batteries multi camera arrays and high refresh rate displays down to their more affordable siblings While there are still some things you ll only find on flagship smartphones you don t have to compromise as much anymore if you re looking for a solid device at a lower price tag If you have less than to spend I can help you figure out what features to prioritize when trying to find the best midrange smartphone What is a midrange phone anyway While the term shows up frequently in articles and videos there isn t an agreed upon definition for “midrange beyond a phone that isn t a flagship or an entry level option Our recommendations for the best midrange smartphones cost between and ーany less and you should expect significant compromises If your budget is higher though you should consider flagships like the Apple iPhone and Samsung Galaxy S What factors should you consider when buying a midrange smartphone Buying a new device can be intimidating but a few questions can help guide you through the process First what platform do you want to use If the answer is iOS that narrows your options down to exactly one phone Thankfully it s great And if you re an Android fan there s no shortage of compelling options Both platforms have their strengths so you shouldn t rule either out Obviously also consider how much you re comfortable spending Even increasing your budget by more can get you a dramatically better product And manufacturers tend to support their more expensive devices for longer It s definitely worth buying something toward the top limit of what you can afford Having an idea of your priorities will help inform your budget Do you want a long battery life or fast charging speed Do you value speedy performance above all else Or would you like the best possible cameras While they continue to improve every year even the best midrange smartphones still demand some compromises and knowing what s important to you will make choosing one easier Lastly pay attention to wireless bands and network compatibility If you don t want to worry about that your best bet is to buy directly from your carrier To make things easier all the phones we recommend are compatible with every major US wireless provider and can be purchased unlocked nbsp What won t you get from a midrange smartphone Every year the line between midrange and flagship phones gets blurrier as more upmarket features and specs trickle down to more affordable models When we first published this guide in it was difficult to find devices with waterproofing or G Now the biggest thing you might miss out on is wireless charging Just remember to budget for a power adapter too many companies have stopped including chargers with their smartphones Performance has improved in recent years but can still be hit or miss as most midrange phones use slower processors that can struggle with multitasking Thankfully their cameras have improved dramatically and you can typically expect at least a dual lens system on most midrange smartphones below The best midrange phones for Google Pixel a The best midrange Android phoneThe Pixel a delivers everything we look for in a great affordable phone New features include a faster Tensor G chip a smoother Hz display and for the first time on one of Google s A series phones support for wireless charging And with a refreshed design with IP water resistance it looks and feels like the standard Pixel but for less You also get great support thanks to five years of security updates and at least three OS upgrades The phone s only shortcomings are rather small and include a lack of a dedicated zoom lens and no support for mmWave G unless you purchase a slightly more expensive model from Verizon iPhone SE rd generation The best iPhone under If you can get past its dated design and small inch display the Apple iPhone SE is the fastest phone you can buy for less than No other device on this list has a processor that comes close to the SE s A Bionic What s more you can expect Apple to support the model for years to come The company is only just ending support for the first generation SE after six years The company hasn t said how long it intends to furnish the latest SE with new software but it s likely to support the device for a similar length of time For all its strengths the iPhone SE is held back by a dated display Not only is the SE s screen small and slow but it also uses an IPS panel instead of an OLED display meaning it can t deliver deep blacks Additionally that screen is surrounded by some of the largest bezels you ll find on a modern phone That s not surprising The SE uses the design of the iPhone which will be a decade old in two years And if the SE looks dated now it will only feel more tired in a few years Samsung Galaxy A G The midrange phone with the best display for streamingFor the best possible display at this price look no further than Samsung s Galaxy A G It features a inch Super AMOLED display that is ideal for watching TV shows and movies Plus the Hz panel is the fastest on this list Other standout features of this Samsung phone include a mAh battery and versatile camera system The A s three shooters may not deliver photos with the same detail and natural colors as the Pixel a but it can capture bigger scenes with its two wide angle rear cameras Like the other Android smartphones on this list the Samsung Galaxy A isn t the fastest performer At best Samsung s Exynos is a lateral move from the Qualcomm Snapdragon G found in the Galaxy A G And though the A is cheaper than its predecessor this Samsung phone no longer comes with a power adapter and headphone jack so the difference may not end up being much OnePlus Nord N G The best cheap smartphone when on a budgetIf you only have around to spend on your next phone you could do a lot worse than the OnePlus Nord N To start this budget phone features a big mAh battery that will easily last you a full day The N also has a Hz display and G connectivity which are tricky to find at this price Best of all it doesn t look like a cheap phone But the N is also a good illustration of why you should spend more on a budget phone if you can It s the slowest device on this list due to its Snapdragon chipset and paltry GB of RAM Its triple main camera setup is serviceable during the day but struggles in low light and doesn t offer much versatility beyond a disappointing macro lens OnePlus also doesn t plan to update the phone beyond the soon to be outdated Android In short the N is unlikely to last you as long as any of the other affordable phones on this list Chris Velazco contributed to this report This article originally appeared on Engadget at	2023-07-24 18:30:06
