海外TECH	DEV Community	Laburanding: como trabajar para afuera	https://dev.to/selene_l21/laburanding-como-trabajar-para-afuera-2ojc	Laburanding como trabajar para afueraBueno la idea de esta charla surge un poco de mi experiencia trabajando remoto con una empresa de afuera y de comentarios consejos que fueron saliendo de dailys y charlas con amigos colegas Les voy a hablar de mi experiencia lo que yo hice y lo que a mi me sirvio no lo tomen como que es palabra santa Mi carrera en It comienza en febrero en una start up de aca de cba donde solo fui a la oficina dos semanas antes de encerrarme en casa donde me paséaño y medio corriendo durmiendo poco y ganándome un burn out por no saber parar A esto sumemosle que me largue a dar clases de programación gracias docta por el aguante y conseguími primer laburo para USA Ahora vamos por partes diría Jack Como con tan poca experiencia conseguítrabajar para USA Esto se dio gracias a una sumatoria de cosas Manija gt Tengo la “suerte que herede la locura de estudiar y sentarme por horas a investigar y leer de mi vieja y eso me permitióaprender bastante en poco tiempo Comunidad amigos me metíen comunidad donde hice proyectos y fui aprendiendo de pares Y mis amigos que también me pasaban cosas me incentivaron y recomendaron para encontrar trabajo OJO gt esto no quiere decir que solo porque te recomienden pum encontras el remoto Estudio y práctica A pesar de ya estar trabajando seguir haciendo proyectos propios me metíen hackatones y el enseñar un curso de programacion me permitióretomar conceptos básicos de javascript y vocabulario técnico que a la hora de las entrevistas es clave desde mi punto de vista Hablemos de trabajo remotoEl trabajo remoto es cada vez más común ya que cada vez más personas quieren tener un horario de trabajo flexible y “gracias a la pandemia más empresas se están sumando a esta modalidad PROS Y CONTRAS DEL REMOTOLos horarios y lugares de trabajo flexibles suelen aumentar la productividad y el rendimiento Te permite viajar y trabajar desde cualquier parte del mundo y convertirte en un nómada digital creando tu propio horario de trabajo No tenes que viajar al trabajo todos los días y ahorras no solo plata sino también tiempoMala conexión de internet muchos ruidos ambiente una compu no tan buena y sin servicio técnico por parte de la empresa te pueden arruinar el día Al no tener horarios y un espacio dedicado para trabajar pueden hacer que seamos más propensos que otros a procrastinar a distraerse fácilmente y no aprovechar el tiempo de manera eficienteAHORA A LO QUE VINIERONLo primero es tener claro quéqueremos hacer y en base a eso armar un plan En mi caso el remoto es porque quiero viajar y seguir trabajando de lo que me gusta Obviamente la suerte juega un papel importante en toda búsqueda pero estos puntos pueden ayudar a mostrar tus habilidades a los posibles empleadores cuando no tienes tanta experiencia Conoce tus puntos débilesSoy pésima en algoritmos y en varias entrevistas me tocóhacer un challenge técnico donde tenía problemas lógicos de algoritmos etc Si sabemos dónde fallamos podemos mejorarlo Aca les dejo algunas páginas donde pueden practicar CodewarsCodingameCodility Repasa conceptosSi bien sabemos que no vamos día a día recitando conceptos de programación tener en claro las definiciones nos pueden ayudar muchísimo No necesariamente tiene que ser con vocabulario ultra técnico pero mientras puedas expresarlo de manera simple o explicárselo a otra persona es suficiente Developer MozillaJS TipsLenguaje JSRefactoring Guru Date a conocerPara mi lo mejor es tener un github donde tengamos proyectos propios copados donde aprendimos y renegamos para mostrar en entrevistas y contar estas anécdotas Aparte permite que otros devs de las empresas en donde postulamos puedan ver nuestro código de antemano y muestra nuestro proceso de aprendizaje Podés encontrar ideas acá Codementor React ProjectsEn LinkedIn podés crear tu propio perfil en donde pones tu historial laboral destaques tus habilidades y resumas tus logros y experiencias laborales anteriores Una buena forma de destacarse es compartir cualquier artículo que hayas escrito y otros contenidos interesantes e informativos Participar en Discord junto a otras personas y comunidades también es una buena forma de hacer networking Contribuir al código abiertoAl principio cuando no tenemos tanta experiencia puede resultar difícil o incluso que nos de vergüenza meternos en un repositorio de otra persona pero esto es algo que a muchos recruiters les llama la atención Podemos empezar haciendo pequeñas contribuciones como corregir errores gramaticales y de tipeo o crear traducir documentación para proyectos que carezcan de ella Esto demuestra que sabemos comunicarnos bien y colaborar con otros desarrolladores de forma remota y asíncrona para resolver un problema Y todo eso es público Podés encontrar una guia de como empezar acá Github para Open Source Lara Díaz・Oct ・ min read Gana experiencia trabajando de forma remotaEsto no es cien por ciento necesario pero hacer trabajos freelance ayuda muchísimo a la hora de encontrar trabajo estable como contractor en comparación con alguien que no tenga esa experiencia y conocimientos WorkanaUpworkFreelancer ¿Dónde encontrar empresas que contraten remoto Yo siempre le pregunto a mis amigos si en las empresas donde trabajan están contratando y que experiencia tuvieron y con quéstack están trabajando También probéotras páginas donde encontrar varias opciones en distintos países no solo USA RemoteOKWe Work RemotlyAngelNearIndeedTodo este post lo podes encontrar en forma de charla acá BeerJS Cba Asi que si estas recien empezando y queres ganar experiencia o queres hacer el salto a remoto animate y espero te sirva el post	2022-02-24 15:08:15
海外TECH	DEV Community	Building an Apache ECharts dashboard with React and Cube	https://dev.to/cubejs/building-an-apache-echarts-dashboard-with-react-and-cube-45i3	Building an Apache ECharts dashboard with React and CubeThis guest post was written by Osinachi Chukwujama He is a web developer and technical writer He enjoys building backend applications and utilizing cloud computing He plays the organ and creates casual animations when he isn t coding You can get in touch with him through his website In a world where every organization has big data a simplified approach to data analysis has never been more sought after Thankfully open source charting libraries like Chart js Recharts and Apache ECharts are robust enough to handle big data analytics Tools like Power BI Snowflake and Cube also help simplify analytics by making it easier for organizations to use their data to make decisions In this article you ll learn how to use Apache ECharts Cube and React to build an e commerce analytics dashboard On completing this tutorial you will have built a React application that displays charts of different metrics in an e commerce store The result should look like this You can find a live demo here or view the React app source code in this GitHub repo What Is Apache ECharts Apache ECharts is a robust JavaScript charting library It s fully packaged offering common chart types like line column and pie and even more complicated chart types like graph themeRiver and gauge ECharts is primarily used for building data applications but it also works well for applications that require a lot of visualized data points It s free to use and its source code is open source which means it s flexible and has longevity It s also incredibly customizable by allowing color and size alteration to fit your application s needs However rendering happens on the client side So if the device that renders the chart is low on memory the visualization will be slower Rendering is faster if you use Google Charts but all your data doesn t live on your own server like it does with ECharts which means it can be viewed by Google or any other third party Unlike Recharts ECharts is primarily a JavaScript library This means that you don t get React components for axes legends and other parts of a chart Instead you ll use an object to declaratively define the rendering and behavior of a chart Why Integrate with Cube ECharts integrates seamlessly with Cube offering superb visualizations for data returned by Cube s API All you need is your data and to build a few queries and feed the resulting API through an ECharts chart Implementing an ECharts Dashboard with React and CubeThe following sample project has three main components A relational database PostgresSQL in this tutorial but you can use MySQL MongoDB or any other database supported by Cube A Cube schemaSetting up ECharts in ReactTo follow along you should have Docker installed Setting Up CubeTo set up Cube using Docker change the directory into the desired location and run the following command docker run p v PWD cube conf e CUBEJS DEV MODE true cubejs cubeThis command downloads the Cube Docker image and opens port to the Cube Playground You can navigate to http localhost in your browser to see the playground From here you re supposed to select the database type and parameters This article will use a hosted Postgres database offered by Cube Choose Postgres as the database type and use the parameters below to complete your Cube instance setup Hostname demo db cube devDatabase ecomUsername cubePassword Generating a Data Schema with CubeCube comes with a schema builder that lets you build your desired queries These queries help you ask analytical questions about your data like the following How many orders were made this month What s the total number of products sold To proceed select all the tables under the public schema in the Schema tab of the Cube playground After selecting your target tables click the Generate Schema button A prompt will appear letting you know that the schema files have been created and you can start building charts Click on the Build button Overview of the Cube PlaygroundThe Cube Playground consists of three tabs The Build tab for building charts from a data schemaThe Dashboard App tab for viewing charts generated in the Build tabThe Schema tab for selecting the tables where the data will be used to build chartsThe schema generated by Cube is a JavaScript object that consists of measures and dimensions It s used to generate SQL code that will be queried against the database for analytics The code snippet below shows a data schema for a users table It contains a count measure and three dimensions that correspond to columns in the users table cube Users sql SELECT FROM users measures count sql id type count dimensions city sql city type string signedUp sql created at type time companyName sql company name type string Cube lets you combine measures and dimensions to ask questions like “Which companies do our users work for measures Users count dimensions Users companyName Or “Where are our users based measures Users count dimensions Users city Setting Up ECharts in a React ProjectTo set up ECharts in a React project create a new React project in your desired directory and start the dev server using the command below npx create react app cube echarts appcd cube echarts appnpm startNow install the required dependencies npm i save cubejs client core cubejs client react echarts echarts for react react loader spinner dayjs react bootstrap bootstrap Basic App SetupNow that you have your dependencies in place create the components folder using this command mkdir src componentsReplace the content of App js with the following import React from react import CubeProvider from cubejs client react import cubejs from cubejs client core import Navbar Container Row Col from react bootstrap export const cubejsApi cubejs process env REACT APP CUBEJS TOKEN apiUrl http localhost cubejs api v const App gt return lt CubeProvider cubejsApi cubejsApi gt lt div className bg gray gt lt Navbar gt lt Container gt lt Navbar Brand href home gt E Commerce Dashboard lt Navbar Brand gt lt Container gt lt Navbar gt lt div gt lt CubeProvider gt export default App You don t have to set the REACT APP CUBEJS TOKEN on your development environment as it is strictly used in production If you do want to set it you need to sign a JWT on or using your favorite tool with the CUBEJS API SECRET as the secret key You can find the CUBEJS API SECRET in the env file of the Cube back end set up which is automatically created by Cube The dashboard will contain four charts An area chart containing the revenue growth over the previous yearA line chart containing orders over the last thirty daysA stacked bar chart containing the orders by status over timeA bar chart containing orders by product category nameTo get started creating these charts create the necessary chart files and loader touch src components AreaChart jsxtouch src components BarChart jsxtouch src components LineChart jsxtouch src components StackedBarChart jsxtouch src components Loader jsxAdd the following to Loader jsx import Oval from react loader spinner function Loader return lt div className d flex justify content center align

海外TECH	Engadget	Samsung Galaxy S22 review: Sprucing up a solid foundation	https://www.engadget.com/samsung-galaxy-s-22-review-sprucing-up-a-solid-foundation-151522033.html?src=rss	Samsung Galaxy S review Sprucing up a solid foundationA lot of gadgets operate on a quot tick tock quot development cycle with the most well known being past iPhones that sported fresh designs only to be replaced months later by more refined but similar looking S variants And after Samsung ticked the box with a fresh new design for last year s S now the company has returned with the more polished Galaxy S and S While they might look a lot like last year s phones there have been some notable upgrades especially on the S s display performance and camera DesignEven though I m still not sure how much I love Samsung s Contour Cut camera design the Galaxy S very much looks and feels like a high end device The outside of the phone features Samsung s Armor Aluminum alloy that s been polished to a near mirror finish with the S also being one of the first phones equipped with Corning s Gorilla Glass Victus to protect the phone from drops and scratches ーboth in front and in back Sam Rutherford EngadgetTo add a little spice to the mixture the S s backside sports a lovely matte texture which does a surprisingly good job of resisting fingerprints And for Samsung also spruced up the S s color options with new shades of green pink and white along with good ole black Like previous Galaxy S phones the S comes with an ultrasonic in screen fingerprint reader and after years of tweaking its algorithm and improving the tech this time it feels seriously fast In my experience unlocking the phone was practically instant and I never really ran into recognition issues unless my fingers were legit wet or greasy Keep your grubby hands away from my phone if you re eating pizza k thnx Sam Rutherford EngadgetThe one thing avid movie watchers should be aware of though is the color matched frames on the pink and white models If you re the kind of person that might be bothered by a glint or sparkle around the edge of the phone while watching videos you may want to go with one of the darker color options And while it s not really a surprise at this point the S doesn t feature a microSD card slot or a headphone jack With the Galaxy S line now being three generations removed from the last device to include both of those features it s pretty clear they re not coming back DisplaySamsung has had a lock on the crown when it comes to making the best mobile displays in the business for a while now But on the S the company has outdone itself once again with displays that can hit a peak brightness of nits on the S or an astounding nits on the S Suffice to say any fears of the S s screen being hard to read even in direct sunlight are unfounded Sam Rutherford EngadgetThen to make things look even better Samsung created a new feature called Vision Booster designed to amp up things like contrast and color saturation in very bright or dim conditions While there s no indicator or pop up that lets you know it s working I found the effect most pronounced when I used the phone outdoors with more subtle changes in the dark when compared to phones like the Pixel Pro I found Vision Booster made dark scenes easier to parse but even when viewed side by side I basically had to press my face up against the phones to really see the differences But regardless of where you are the end result is a display that lives in technicolor pumping out vivid shades and hues along with the perfectly dark inky blacks that make OLED screens so enthralling Plus thanks to a x resolution and a variable Hz refresh rate everything from photos to gifs look sharp and crisp PerformanceThe Galaxy S line is one of the first phones to feature Qualcomm s new Snapdragon Gen chip which when combined with GB of RAM and GB of storage or GB if you opt for the upgrade results in a phone that feels blisteringly fast In my experience there isn t really anything you can throw at the S that makes it even sweat aside from stuff like hardcore multitasking when connected to an external monitor via Samsung Dex which is still very much a thing Sam Rutherford EngadgetAnd while some reports claim that Qualcomm s Snapdragon Gen Gen has a proclivity for running hot S s built in vapor chamber cooling system seems effective at keeping throttling to a minimum Compared to the S FE which features an older Snapdragon chip our S posted scores in Geekbench s Compute test around percent higher vs And while the gap wasn t quite as large in Geekbench s CPU test the S still posted a significantly higher single core score of compared to for the S FE As for wireless connectivity all versions of the S and S support all the important flavors of G including Verizon and AT amp T s new C band spectrum CamerasAfter recent advancements from competitors like the iPhone and Pixel Samsung is now playing catchup to Apple and Google in the camera department And while Samsung is touting a bunch of new camera features for the S and S like Adaptive Pixel and various quot Nightography quot improvements the real upgrades are the S s new sensors ーparticularly the one for its MP main cam Sam Rutherford EngadgetThanks to that significantly higher resolution up from MP on the S photos from the S s main wide angle camera are just flat out sharper than before But more importantly the S s primary camera offers wider dynamic range and big improvements for low light photos In darker scenes the S uses a four to one pixel binning technique that combines four adjacent pixels into one big pixel which allows for improved light sensitivity The result is brighter photos with richer colors especially at night And even though Google s Night Sight still has a slight advantage over Samsung s Night Mode the S has seriously narrowed the gap Elsewhere you also get a solid MP ultra wide camera with a degree field of view and a MP telephoto camera with a x optical zoom the latter of which is important because neither the standard iPhone or Pixel comes with a dedicated zoom lens So once again the base S is the most well rounded camera phone for the money And in front the MP selfie camera captured crisp pictures of my face including my many pores and blemishes though you can always play around with Samsung s beauty settings if you want to put on a smoother face for social media Where things get frustrating is that some of the S s new camera features are often hard to use or even tell when they re working ーwith the main offender being Samsung s Adaptive Pixel feature Adaptive Pixel uses multi frame image capture to shoot pics using the main sensor s full resolution along with lower res pixel binned shots before merging them together to create a higher quality composite final image The issue is that Adaptive Pixel isn t turned on by default and searching the phone s settings for it doesn t return any matches To even activate this you need to first make sure Samsung s scene optimizer is on then you have to turn on the camera app s full MP capture mode make sure the Detail Enhancer setting is disabled and then point the S at a dark scene and hope Adaptive Pixel kicks in And I do mean hope because there s no pop up or notification that lets you know when the feature is activated Even when you do get it to work while the pictures are a bit sharper and feature a more neutral color profile which is better for anyone who wants to edit their pics later Adaptive Pixel doesn t really produce magically superior images like Samsung s marketing may have led you to believe Sam Rutherford EngadgetThat s kind of a shame after all the attention Adaptive Pixel got during the S s debut at Samsung s recent Unpacked event Thankfully other new camera features like Auto Framing work as advertised allowing the phone to track up to people s faces when capturing video while Samsung s Advanced OIS ensures that your clips look smooth and shake free The company s AI Stereo Depth Map technique also makes the phone a bit better at differentiating between your subject s face and the background in portrait mode though you may have to do some serious zooming in to really see the difference In short I like a lot of the changes Samsung has made to the S s camera setup raising its general photo prowess even if some of the phone s new software don t quite live up to expectations SoftwareSam Rutherford EngadgetThe Galaxy S line comes with Samsung s One UI which is based on Android That means because it has long supported features like scrolling screenshots the main upgrades in Samsung s latest Android skin are the new Privacy Dashboard and customization options for your home screen app icons and the phone s UI Similar to what s available in Google s Pixel phones the customizations allow you to set a consistent color palette across your phone s menu while new mic and camera notifications make sure you know when apps are accessing critical hardware components Other software upgrades include Live Sharing in Google Duo which is a Samsung exclusive feature that lets you share your screen during video chats It s simple and effective even if it s not quite as full featured as Apple s SharePlay in iOS And for those looking to keep better track of digital documents like your ID credit cards and even digital car keys Samsung also made a new Digital Wallet that can securely store all those things in one place Battery lifeSam Rutherford EngadgetFeaturing and mAh batteries respectively both the S and S have respectable longevity But if lasting a long time between charges is really important for you the S is definitely the better pick as it lasted hours and minutes on our local video rundown test compared to just hours and minutes for the standard S And thanks to its W wired charging up from W charging on the S the S juices up way faster too In both cases though you ll need to make sure you have the proper power brick as neither phone comes with a charging adapter in the box S vs S Aside from the obvious differences in screen size inches vs inches and overall dimensions x x inches and ounces vs x x inches and ounces there are a few other features that separate the S and S The S is limited to watt wired charging while the S gets watt wired charging with both phones also featuring W Qi wireless charging and W reverse wireless charging aka wireless power share Other differences include slightly faster WiFi speeds on the S thanks to support for WiFi E compared to standard WiFi for the S The S also has built in UWB connectivity which isn t available on the S UWB is one of many protocols used to send files to other devices wirelessly via Nearby Share though that s not really a big deal since Nearby Share still works albeit less swiftly over WiFi and Bluetooth The other consideration is that for people looking to use digital car keys from automakers like BMW and others those often work better and have longer ranges using UWB compared to NFC which might make the S a better choice for more tech savvy new car buyers Wrap upSam Rutherford EngadgetThe Galaxy S isn t a huge improvement or departure from last year s phone but just like an quot S year quot iPhone Samsung has tweaked and elevated all the phone s most critical components You re getting a more refined design improved performance a sharper main cam with better low light photography and an even brighter screen And that s saying something from the king of mobile displays Sure some features like Vision Booster and Adaptive Pixel are more subtle or harder to use than I d like but putting all this in a chassis sporting excellent build quality and other premium features like IP dust and water resistance reverse wireless charging and more is a formula that s hard not to like And with a starting price of for the standard S you re getting more phone for the money than anything you can buy from Apple or Google	2022-02-24 15:15:22
