海外TECH	DEV Community	O poder de uma boa inteligência artificial	https://dev.to/isabellaherman/o-poder-de-uma-boa-inteligencia-artificial-bpj	O poder de uma boa inteligência artificialEnglish version here Cada vez mais as I A s Inteligência Artificial estão presentes no nosso dia a dia Desde assistentes virtuais que te contam uma piada te contam curiosidade ligam as lâmpadas e fecham as portas da sua casa atésoluções em grandes empresas corporativas Se fosse possível dar um pulo na década de iríamos acompanhar o surgimento das IA s nos jogos e ver que IA em videogames éuma ramificação distinta e diferente da IA ​​acadêmica e o principal motivo éque ela lida e reflete comportamentos humanos Os seres humanos não são máquinas fomos feitos para viver em sociedade conversamos com quem nos identificamos Nesse artigo eu descarto a ideia de “os opostos se atraem O jogador tem que se identificar com o mundo e uma boa IA vai te ajudar nisso Do ponto de vista técnico uma IA para jogos nada mais éque um monte de condições “if aqui “if ali “if lá Mas se essas condições partirem de um olhar crítico do ponto de vista psicológico o jogo muda IA vs MENTE DO JOGADOROs jogadores não querem uma boa IA no seu jogo Os jogadores querem experiências que façam eles se sentirem no poder se sentirem bons em algo querem ser recompensados com a vitória Os seres humanos não são máquinas temos reações que devem ser exploradas pelo game design “Ah mas se os jogadores não gostam de uma IA difícil por que Dark Souls faz tanto sucesso A resposta ésimples A IA de Dark Souls não édifícil o jogo também não Ele sótrabalha numa soft skill muito rara nas pessoas hoje em dia a paciência Paciência em esperar para ler e entender os passos de cada agente do jogo Étão simples mas como éuma dificuldade real nos dias de hoje o jogador se sente o melhor do mundo ao vencer um combate Ficou claro a diferença de complexidade e desafio O design e aplicação de IA s devem ser desenhados para estimular uma sensação de superioridade e controle com o jogador enfrentando situações que equilibram a dificuldade Por exemplo vocêestáproduzindo um jogo que se passa na segunda guerra mundial Em um cenário de guerra énormal encontrarmos inimigos armados bombas de fumaça minas terrestres tanques de guerra automóveis blindados etc Vocêpensou em uma missão onde o jogador teráque parar o avanço de um caminhão blindado carregado com suprimentos para o exército inimigo O caminhão tem uma vida X e pode explodir com o jogador atirando explosivos por exemplo mas quanto tempo isso levaria A resistência de um automóvel blindado émuito mais forte do que o poder destrutivo do armamento do jogador podendo causar uma experiência cansativa com o passar do tempo Com uma IA podemos achar soluções mais interessantes O caminhão émuito forte porém ele édirigido provavelmente por um NPC non player character então como o jogador pode tirar a atenção desse NPC pra que ele pare o caminhão desça para ver o que estáacontecendo assim permitindo um combate mais justo e uma experiência de vitória positiva O jogador pode usar bombas de fumaça arremessar objetos usar sinalizador entre outros eventos que façam sentido no contexto Uma simples condição com o olhar voltado ao psicológico do jogador gerou um sentimento de vitória e superioridade dele em relação ao jogo Entender as reações emocionais do jogador que estão ligadas com as ações do jogo éfundamental O PAPEL DA IA NA IMERSÃOUm grande erro dos jogos quando o assunto éimersão écolocar o jogador como o único ser vivo do jogo o que não estáerrado em teoria mas como criadores de jogos precisamos ser mais céticos com a realidade A franquia GTA tem sua importância e notoriedade na indústria e vende a ideia de um universo com experiência realista de mundo aberto que parece mais um simulador de dirigir carro Vocêentra no carro vai do ponto A ao B e todo universo do jogo praticamente para esperando o jogador concluir o que estava fazendo Experiência de um mundo aberto onde o centro das atenções éo personagem principal não funciona O personagem principal deve ser o centro de atenção do jogador não do mundo Vamos fazer uma analogia da nossa vida como se estivesse representada em um jogo Hoje vocêprecisa acordar e ir para o trabalho esse éo compromisso mais importante do dia então essa ésua missão principal Enquanto se arruma para o trabalho vocêcomeça sentir uma azia às vezes épela comida mexicana que vocêjantou na noite passada e então decide passar em uma farmácia a caminho do trabalho Diferente do trabalho vocênão necessariamente precisa ir na farmácia mas vai te beneficiar em algo além de ter ligação com alguma ação do seu dia então essa passa a ser sua missão secundária Atéaíbem comum como nos jogos mas a vida não para aí Não para aíporque o mundo émuito maior e existem outras pessoas variáveis acontecimentos etc que devem ser levados em conta se vocêtem uma proposta de mundo aberto No Far Cry existe uma IA diretora que se assegura de manter o universo vivo Novamente levando em conta a temática de guerra éde se esperar que existam pessoas precisando de ajuda não sóem situações de sequestro ou invasões mas também em ajuda de arrumar algo que quebrou e a realidade delas não deve ter nenhuma relação com você jogador que estáno papel de um recém chegado do exército Qual seria o sentido de colocar um evento aleatório como esse no seu mini mapa Nenhum Mas ele ainda estálá porque o universo de um jogo de mundo aberto é e deve ser maior que o universo do personagem principal E éaíque a magia da imersão do Far Cry entra Se vocêestiver usando fone épossível ouvir os NPCs te chamando sem nenhum aviso na tela perguntando se vocêpode ajudar tal qual seria no mundo real Esse mesmo exemplo se aplica ao GTA écomum conforme o jogo desenrole apareça no minimapa do jogador um símbolo de pessoas aleatórias que vocêpode oferecer carona mesmo essas não tendo relação alguma com a lore do personagem Mas sejamos honestos um dos maiores desafios dos desenvolvedores de jogos émontar um sistema de jogo mundo aberto que funcione construindo eventos interessantes e diversificados para os jogadores explorarem e se ao longo desses anos de franquia a RockStar pecou nesse quesito ela com certeza jáse redimiu com o título Red Dead Redemption na qual IA atua na imersão do universo com maestria As comparações de Far Cry e Grand Theft Auto V param por aqui mas vamos explorar tecnicamente como a IA diretora comanda todo território do jogo e faz ele parecer mais vivo IA DIRETORA NA PRÁTICAPrimeiro vamos entender o conceito de Systemic AI IA Sistêmica uma estrutura sistêmica dependente de NPC s inimigos civis aliados animais etc Cada agente NPC citado tem sua própria estrutura de comportamento e gerenciar todos eles juntos não éuma tarefa simples e muito menos fácil éagora que a IA diretora entra Uma IA Diretora cujo o nome ébem sugestivo assim como o diretor de uma organização controla o ritmo adequação e intensidade dos eventos de um jogo A imersão do universo de Far Cry ésem dúvidas uma das melhores que jájoguei levando em conta a época que o título foi lançado e as melhorias técnicas desde o seu antecessor Far Cry que foram reconhecidas por críticos da indústria conseguindo uma nota no metacritic A IA diretora de Far Cry monitora os passos do jogador acompanhando o mesmo por um raio de metros e popula esse raio com os eventos do jogo Mesmo com o raio limitado popular esse raio com toda a cadeia sistêmica teria um custo computacional muito alto então a IA diretora conta com a regra de se o player não vê logo não acontece Somado a essa supervisão geral cada agente NPC éregido por uma máquina de estados finita FSM um modelo matemático usado para representar circuitos lógicos muito comum em jogos principalmente pela necessidade de pouco processamento A FSM de cada agente éprojetada para reagir aos estímulos próximos feitos pelo jogador Fiz o diagrama acima analisando o comportamento de um animal carnívoro dentro do jogo FC Esses tópicos representam os comportamentos designado a esse circuito A seguir os estímulos que desencadeiam as ações da FSM Lógica dos componentes iniciais do diagrama enum type Prey Predator enum agentBehaviour Awake Hunting Eating Patrolling Recovering case agentBehaviour Awake if type type Predator if gt se estiver faminto agentBehaviour Patrolling break case agentBehaviour Patrolling achou um type prey no range agentBehaviour Hunting break Éclaro que para cada um dos casos exibidos existem N funções que devem ser analisadas para completar a lógica de cada um dos estados Vocêpode considerar como um exercício analisar o diagrama e terminar a lógica restante ou atémesmo criar o seu próprio diagrama analisando a IA de algum jogo que te agrade Esse émeu primeiro artigo e espero que ele tenha apresentado um outro ponto de vista em cima de um assunto que cada vez mais se populariza

海外TECH	DEV Community	Connecting to PostgreSQL using GORM	https://dev.to/karanpratapsingh/connecting-to-postgresql-using-gorm-24fj	Connecting to PostgreSQL using GORMThis article builds up on the last part where we built a simple REST API with Go Now let s connect our API with a real database Here we will use PostgreSQL and GORM to accomplish this All the code from this article is available hereI ve also created a video if you will like to follow along SetupBefore we start working with the code we will need postgres database for development Easiest way to do this is by using Docker So make sure you have docker installed Now let s define our docker compose yml file that will make it even easier to work with the database version services database container name database image postgres restart always environment POSTGRES USER pg POSTGRES PASSWORD pass POSTGRES DB crud ports volumes db var lib postgresql data volumes db Let s start our Postgres container docker compose up dConnecting to our databaseOnce we have our database running we can connect to it via any database management tool such as pgAdmin Here I ll use TablePlus and create a connection of type PostgreSQL Let s add all the details same as we did in docker compose yml So our user is pg password is pass and database is crud After that we can click on test to verify that we can reach our database Then click connect Now we should be able to see our tables Setting up GORMLet s install GORM and Postgres driver go get u gorm io gorm go get u gorm io driver postgresUpdate ModelsLet s go to pkg models book go and declare our Id as primaryKey in our struct tags package modelstype Book struct Id int json id gorm primaryKey Title string json title Author string json author Desc string json desc DB packageNow let s create a db package in pkg db db go In our Init function we ll simply open a connection to our Postgres database using the dbURL Also we can use db AutoMigrate to migrate our models Note We can also store the dbURL as an environment variable but to keep things simple we ll just add it right here package dbimport log github com tutorials go crud pkg models gorm io driver postgres gorm io gorm func Init gorm DB dbURL postgres pg pass localhost crud db err gorm Open postgres Open dbURL amp gorm Config if err nil log Fatalln err db AutoMigrate amp models Book return db Dependency InjectionNow that we have db setup let s think how we ll use that in our handlers We cannot call Init in each handler as this will create lots of database connections So we will initialize it once and pass it to our handlers For that we can make use of dependency injection Here let s declare handler struct package handlersimport gorm io gorm type handler struct DB gorm DB func New db gorm DB handler return

海外TECH	DEV Community	Building TailwindCSS with Sass	https://dev.to/deepcodes/building-tailwindcss-with-sass-4ap0	Building TailwindCSS with SassAccording to the state of CSS report Tailwind CSS stood out as one of the tools with the highest satisfaction ratio Tailwind has become a go to solution to build web applications And the reason is justified you can build and ship websites faster and still have control over the styling unlike other CSS frameworks Bulma bootstrap etc I was always curious about how tailwind generates kB of CSS which is full of utility classes from p mx pt to the color variants and all This blog covers how you can build TailwindCSS utility classes in a very minimal way and doesn t cover the plugin config ecosystem it provides We will be building it with the help of Sass SCSS or syntactically awesome stylesheets If you don t know what this is you can watch this video to get an overview Using Sass will help us to write CSS code more efficiently and programmatic Browser doesn t understand what Sass actually is so we need to compile it to CSS We will use a bunch of tools to accomplish that Now let s start by setting up our project yarn init y ornpm init yThis would create a minimal package json file for our project Now we will add some devDependenciesyarn add D autoprefixer node sass postcss postcss cli ornpm install autoprefixer node sass postcss postcss cli save devA brief explanation of what these actually do node sass helps in compiling scss sass files to csspostcss parser which tokenizes CSS code to create an abstract syntax tree we will be using it s pluginsautoprefixer plugin of postcss adds vendor prefixes to CSS ruleNow will add some scripts in package json feel free to modify the input and output of your build scripts build rm rf build amp amp yarn build sass build sass node sass output style expanded src index scss build index css amp amp yarn build autoprefix build autoprefix postcss use autoprefixer map output build index css build index css build clears build directory and runs build sassbuild sass compiles scss and build css in a new directory then runs build autoprefixbuild autoprefix adds vendor prefixes and generates source mapsNow let s create our input file src index scss if you write some valid scss code and run yarn build you should see the compiled css created Now that our project is setup we will look into creating text color amp background color variants of tailwind The base idea is to loop over all colors you have and generate utility classes text gray bg gray etc Let s start by first creating a new directory utils and a file inside it colors scss Adding a leading underscore in scss files is called partials this helps us in modularizing the code and importing it into other files To declare our colors we will use Maps which is provided by SASS to declare key value pairs utils colors scss colors gray ffafc gray edff gray eef gray cbde gray aaec gray gray a gray d gray ac Now to loop over these we will use each rule this helps us to evaluate code for each element of a lists maps to generate repetitive styles which is exactly what want to do utils colors scss each name hex in colors text name color hex bg name background color hex Now let s import this partial in our input file src index scss import utils colors On running yarn build you should be able to see all your utility classes being generated build index css text gray color ffafc bg gray background color ffafc text gray color edff bg gray background color edff and so onMoving on to the next part we will look into creating margin padding utility classes We will be using lists data type in this case Let s start by creating a new partial spacing scss and we will create lists st one would be spaces which will be used to calculate the spacing For eg m gt margin rem and the nd one being sides which is basically the direction of spacing to create margin top right left bottom variants utils spacing scss spaces sides top right bottom left Now that we have our values all we have to do is now loop over them with the help of the each rule To generate margin padding top left bottom right utility classes we will nest another each rule to map over sides lists We will also use str slice which returns the slice of string utils spacing scss each space in spaces m space margin space rem mx space margin left space rem margin right space rem my space margin top space rem margin bottom space rem px space padding left space rem padding right space rem py space padding top space rem padding bottom space rem p space padding space rem each side in sides m str slice side space margin side space rem p str slice side space padding side space rem Make sure to import the partials in our input file src index scss import utils colors utils spacing Now if you build it you should see the spacing variants generated build index css m margin rem p padding rem mx margin left rem margin right rem my margin top rem margin bottom rem and so onUsing the same approach you can create breakpoints typography literally any kind of utility classes you want I hope you found this article informative I thought this was cool enough implementation to share with you folks You can refer the code in this Github repo Let me know what you think about it feel free to connect with me on Twitter if you have any questions

海外TECH	DEV Community	5 Programming Principles To Live By	https://dev.to/trevoirwilliams/5-programming-principles-to-live-by-1km8	Programming Principles To Live ByAs programmers we try to follow certain rule and patterns to govern how we write code that delivers software While these patterns might not make the software work better they are important for the maintenance and longevity of the application and contribute to easily newer developers can take up the baton and run Never forget that code should be reusable and maintainable The following are principles that will help you to maintain those standards KISS Keep It Simple Stupid or Super Simple This is first on the list because it can determine how easily another developer can come and see and understand your code Frankly it also affect how well you can understand it after a weekend off Commenting code is good but when code is written in a simple and efficient manner it can speak for itself Always ensure that your code is solving specific problems using the simplest and most understandable techniques possible DRY Don t Repeat Yourself Sometimes it seems harmless to repeat a block of code But then we need the block another time and in another place Then the requirement changes that s places that this block of code was repeated and additional bouts of maintenance work This is why methods and then classes exist Try to abstract code that will be used multiple times and place in a central location that other places and developers can access it This makes it easier to maintain in the long run and takes pressure off of maintenance and refactoring activities YAGNI You Aren t Going To Need It I have seen too many times where the super star developer on the team writes some code for an edge case Edge case meaning maybe it will maybe it won t Sometimes the code is no longer needed and they just comment it out and leave it there just in case If you don t need code now then don t write it That is time that could be better spent ensuring that the current objectives are being met with relevant code Also don t develop attachment syndrome to code that is being deprecated If you are using source control then you can always retrieve the version of the code after you have removed not just commented but removed it from the code base This ultimately leads to much cleaner code and readability Separation of ConcernThe foundation of this principle is that you should always ensure that your blocks of code are dealing with one thing at a time In practice this isn t always easy to accomplish based of the framework or even language you are using but it is something to always remember Here are simple examples of how this can be ensured A function should complete one operation Don t have it doing or eg Sum int num int num Anything written in that function should be towards a single outcome eg Sum returns Not Product and quotient All functions related to common tasks should be put into one class class Calculator int Sum int num int num int Difference int num int num int Product int num int num int Quotient int num int num All related classes get compiled into one library I am sure you get the point ensure that your code has one major task to completed per block Do A Design DocumentSometimes in our zeal we rush head first into development based on a vision and then end up making major changes in the middle of it all It is important to have a clear design and I would extend that and say design document This helps you to think ahead and realize potential gaps beforehand and have a clear goal and path in mind ConclusionSometimes it is not about being a great programmer it is more about being proficient but adhering to good habits You might not always get it right the first time but always be willing to critique yourself and accept feedback as you grow in your profession	2021-12-01 13:12:52

海外TECH	DEV Community	What is autonomous cloud cost optimization and what can you gain from it?	https://dev.to/castai/what-is-autonomous-cloud-cost-optimization-and-what-can-you-gain-from-it-4bkn	What is autonomous cloud cost optimization and what can you gain from it You ve probably heard about automated cloud cost optimization but what about autonomous cloud cost optimization  How does this type of optimization actually work What mechanisms does it use to reduce cloud bills  Keep on reading to find out Here s a quick guide to autonomous cloud cost optimization What is autonomous cloud cost optimization Here s how an autonomous Kubernetes platform worksStep Automated analysisStep Reaching the ideal state with Instant RebalancingStep Staying optimized automaticallyWhat is autonomous cloud cost optimization Autonomous optimization means that all the optimization tasks are triggered without any active involvement from the DevOps or cloud engineer But it s more than automation  An autonomous solution connects multiple areas of automation together to work in one smooth flow Automated analysis of the cloud resources that identifies areas for optimization Getting you to the optimized state automatically Keeping the optimized state under changing conditions automatically without involving engineers in proactively managing the infrastructure  A platform should do all three things to be considered autonomous Here s how an autonomous Kubernetes platform worksCAST AI is a fully autonomous cloud cost optimization platform that supports Kubernetes clusters running on AWS Google Cloud Platform and Microsoft Azure Cloud Here s a step by step guide to how it optimizes Kubernetes clusters Step Automated analysisTo find out how much we could save through the Cluster Analyzer we need to connect our cluster to CAST AI So we create a free account on and select the Connect your cluster option To connect the cluster we need to run a small script in our AWS GCP or Azure terminal How secure is connecting a cluster to CAST AI To deliver meaningful results to you CAST AI needs minimal cluster access The platform was created by security specialists and has achieved both SOC Type II and ISO certifications so it follows the principle of least privilege  The read only agent launched when you run a script we provide in your terminal cannot change any cluster configuration or access sensitive data The agent code is open source and you can see it in our GitHub repository  To learn more about how the agent works take a look here How does the read only CAST AI agent work and what data can it read For more on security features check out this guide to security and privacy in CAST AIThe Savings Report shows what the CAST AI engine would do if we put it in charge of managing our nodes This is what the report looks like note the contrast between the Current Cluster and the Optimized Cluster at the bottom In this example the platform shows that we re overprovisioning our cluster We can see how three virtual machines nodes could do the exact same jobs as the six machines we re using  for a fraction of the cost At this point we can choose between two options Turn autonomous optimization on the platform will then rebalance our cluster to achieve savings and allow for continued optimization around the clock finding the best opportunities for getting the performance we need for of the price or less Change our setup manually to what CAST AI suggested doing that also means that we d have to run the reports and do all the required actions manually on a regular basis Not all of the optimizations can be implemented manually with a similar level of efficiency for example autoscaling or managing spot instances Step Reaching the ideal state with Instant RebalancingCAST AI uses the cluster Instant Rebalancing feature to achieve the optimal configuration in a few minutes In our example six nodes were reduced to three nodes with zero trade offs on performance The platform achieved that by seamlessly moving our workloads from the existing nodes to nodes achieving greater resource utilization The cluster now costs per month instead of the initial savings Let s take a look at our cluster before and after rebalancingBefore rebalancing The cluster has six nodes and costs per month After rebalancing The cluster has three nodes that ensure the exact same level of performance as before only for per month Once the process is completed we get a report summarizing what has been done Cluster Rebalancing with spot instancesIf we decide to use spot instances in our cluster we can enable the corresponding policy in the CAST AI console so the engine includes spot instances in its search for the most optimal compute resources Spot instances are virtual machines sitting idle and cloud service providers offer them for a greatly discounted price even off the on demand cost The only catch is that the provider can reclaim these resources at any time Naturally an autonomous platform first checks if and how many of the workloads are spot friendly In our example CAST AI discovered that pods are spot friendly This means that the workloads running on those pods will be able to handle the interruption gracefully By allowing the platform to use spot instances we drove the monthly bill down to per month a further decrease from our optimized setup Try rebalancing now to see your cluster go from zero to optimized in minutes It s available in all of our paid plans You can either sign up yourself or talk to someone in our team beforehand Step Staying optimized automaticallyOnce it achieves an optimized state of the cluster CAST AI engages Day Ops strategies that continuously optimize the cluster in a feedback loop CAST AI analyzes the configuration in real time and makes predictions about cluster requirements It rightsizes our cluster to the right number type and size of compute resources For spot instances CAST AI includes the Spot Fallback feature that guarantees capacity by temporarily moving workloads to other nodes until there are new spot instances available Every time a scale up event occurs for example your application gets lots of traffic because of an ad CAST AI chooses the best resources for the job This includes on demand instances and spot instances that work with any Reserved Instances or Savings Plans that we might have at the moment The platform uses a number of tactics to ensure continuous optimization of the cluster Smart selection of the most efficient virtual machines for the job Automatic selection of spot instances for any spot friendly pods Constant checks for pods that could be reshuffled to empty and delete nodes Autoscaling resources to meet the application s demands
