海外TECH	DEV Community	How to use the command line	https://dev.to/nevulo/how-to-use-the-command-line-11de	How to use the command lineWhether it d be in movies or over the shoulder of your “hacker friend it s likely you ve seen the mysterious command line interface at one point or another A window on the computer purely used for typing commands and getting back results in text Being able to use the command line with confidence opens some interesting doors and allows you to navigate your computer and automate tasks more effectively and efficiently But if you re starting out it can feel like a steep learning curve coming from purely graphical interfaces After all when opened all you re left with is a blank screen and a blinking cursor What are you supposed to write What does it help us accomplish First what is the command line The command line also known as the command prompt or terminal is ultimately a window that lets us enter text to input commands and can display the output of commands back to us in the same window It s like having a text message conversation directly with your computer where you can give more explicit instructions to the computer than you could through a normal graphical interface or using a mouse It s essentially a different “mode of interacting with your computer anything you could typically do through a graphical interface you can likely do on the command line as well The command line is also at the heart of a lot of automation This allows us to write programs through scripts a set of instructions to be carried out by the computer in a logical order Why use the command line The main benefit from using the command line is providing a consistent means of performing actions on your computer and the ability to automate tasks This is how your computer does a lot of the tasks it needs to do “in the background Your software may use the command line to perform certain tasks such as reading writing files changing system preferences or running other programs Imagine if we wanted to do a simple task like creating a folder but we had to specify exactly where the mouse should be and when to press the left or right mouse button Considering the fact that everybody has different screen resolutions different operating systems and potentially different themes across systems it s pretty difficult to get it working for everybody in a simple way To create a folder through the command line we can just write mkdir folder name m a k e a directory a folder where the name is folder name Simply put utilising the command line can often provide more efficiency when performing complex tasks Even though it can seem scary it typically provides an easier and quicker way for us to do things like run applications that we make test our software and much more Many servers run operating systems with a foundation called “Unix These systems are characterised around modular design known as the Unix philosophy The idea is that the operating system provides a set of simple tools programs each with a well defined function or purpose You can construct a pipeline which feeds the output from one command to another which can be combined into complex workflows using a shell like Bash How do you use the command line The best way to start learning to use the command line is just using it To start using the command line follow the instructions depending on which system you re using WindowsThe “command prompt is equivalent to the command line and it can be launched just like any other program on your system To start the Command Prompt Tap on the Windows logo in the taskbarStart typing “cmd executable name for command prompt click the first result You can also search directly for “Command Prompt Optionally right click and select “Run as administrator to run with administrator privileges take caution macOSLaunch the Terminal just like any other program on your system Open Spotlight search Command Space Type “Terminal and click the first result LinuxThere are a few ways to open a terminal in Linux but the quickest way is typically through a direct keyboard shortcut Ctrl Alt T If the keyboard shortcut doesn t work or is hard to remember you can also launch the Terminal just like any other app on your system Press the Super key acts as the “Windows key on most keyboards Start typing “Terminal in the search box at the top Anatomy of the command line Prompt gt The very first thing you ll see when booting up the command line terminal is often an arrow or some sequence of characters behind the text you ll be entering This is known as the “prompt It literally prompts the user to act and type a command It indicates the fact the system is ready to take commands Don t be alarmed if yours looks different or if you re not sure what everything means Executables and commandsAn executable file command or program is usually the first step in performing any kind of action on the command line Your system has hundreds probably thousands of executables installed by default for performing common tasks such as modifying files running scripts etc In the image above echo is a command entered after the prompt The purpose of the echo command is to literally echo back what you write whatever you insert as arguments after the echo command will be printed back in the command line “echo Hello world would display “Hello world in the command line after you press ENTER ArgumentsExecutables can accept “arguments or “parameters these are essentially inputs provided by the user so we can get the result we want If we want to remove a specific file on our system we can perform the action through an executable in this case rm which removes files and we can specify the file to be removed in the arguments rm hello txtThe command above would remove a file called “hello txt if it exists OptionsCommands can also take what are known as “flags or “options which are intended to modify the behaviour of the program in some way For example the echo command mentioned earlier has one option you can choose to pass in n The purpose of this option is to change the behaviour of echo so it doesn t print a new line after printing the user input to the command line Getting help with commandsAs you ve probably noticed the command line is a lot more focused on functionality over user experience and it s not super apparent what some executables commands do on the surface such as rm or mkdir Thousands of commands are out there and it s challenging to remember what most of them do If you need to get further details on what a certain command does the easiest way to do this is often by typing man command in the command line man is an executable used for displaying the online manual pages for system commands and other definitions Some executables also include a h or help option to give more information about what s available to you or what certain arguments do git is a great example of this if you type in git help you ll get a list of common commands you can use within the git executable If you type git branch help you ll get even more detailed instructions about how to use the git branch command specifically and what arguments options are available The methods listed above may be a bit verbose in some cases and might not help you if you want a certain command explained in a simple way You can often use search engines to help find better definitions for commands or if you re trying to find out what command you need to use for a certain operation As a rule of thumb won t apply to everything the names of commands are typically just shortened versions or acronyms of the function they perform If you want to m o ve a file the command is mv c o pying a file can be achieved through cp etc A tool I ve used lately is shell how where you type in a command and it ll try to break down what each “part of the command means ️A word of warningAs I ve talked about before computers are very literal minded They really have no distinction between “good or “malicious instructions they just do what we tell them to do Thus it s important to be cautious when entering commands directly in the command line Unlike graphical interfaces executing commands often comes with no warning or ability to undo so you should avoid executing commands if you re unsure of what they do The command line comes with a lot of power It exposes low level access to different parts of the system so even innocuous short commands can completely break your system or cause data loss if not used carefully I encourage you to do research if you re unsure about what a command is supposed to do or why you d need to run it Stay safe	2022-04-21 15:22:14

海外TECH	DEV Community	Un manual práctico sobre los sistemas de módulos de JavaScript	https://dev.to/khriztianmoreno/un-manual-practico-sobre-los-sistemas-de-modulos-de-javascript-lkl	Un manual práctico sobre los sistemas de módulos de JavaScriptHoy te daréuna introducción práctica sobre los sistemas de módulos que usamos cuando construimos bibliotecas en JavaScript A medida que una aplicación web o biblioteca crece y se agregan más funciones la modularización del código mejora la legibilidad y el mantenimiento Esta guía rápida le daráuna visión incisiva de las opciones disponibles para crear y consumir módulos en JavaScript Si alguna vez se ha preguntado cuáles son los pros y los contras de AMD ESM o CommonJS esta guía le brindarála información que necesita para elegir con confianza entre todas las opciones Una historia de módulos de JavaScriptSin funciones nativas integradas para espacios de nombres y módulos en las primeras versiones del lenguaje JavaScript se han introducido diferentes formatos de módulo a lo largo de los años para llenar este vacío Los más notables que le mostrarécómo usar en su código JavaScript a continuación son Expresión de función inmediatamente invocada IIFE CommonJS CJS Definición de módulo asíncrono AMD Definición de módulo universal UMD Módulos ECMAScript ESM La selección de un sistema de módulos es importante al desarrollar una biblioteca de JavaScript Para los autores de bibliotecas la elección del sistema de módulos para su biblioteca afecta la adopción por parte del usuario y la facilidad de uso Querráestar familiarizado con todas las posibilidades Expresión de función inmediatamente invocada IIFE Immediately Invoked Function ExpressionUna de las primeras formas de exponer bibliotecas en el navegador web las expresiones de función invocadas inmediatamente IIFE son funciones anónimas que se ejecutan inmediatamente después de ser definidas function Module s Implementation Code Un patrón de diseño común que aprovecha los IIFE es el patrón Singleton que crea una única instancia de objeto y código de espacios de nombres Este objeto sirve como un único punto de acceso a un grupo específico de funciones Para ver ejemplos del mundo real no busque más alládel objeto Math o la biblioteca jQuery ProsEscribir módulos de esta manera es conveniente y compatible con navegadores más antiguos De hecho puede concatenar y agrupar de forma segura varios archivos que contienen IIFE sin preocuparse por las colisiones de nomenclatura y alcance ContrasSin embargo los módulos IIFE se cargan sincrónicamente lo que significa que ordenar correctamente los archivos del módulo es fundamental De lo contrario la aplicación se romperá Para proyectos grandes los módulos IIFE pueden ser difíciles de administrar especialmente si tiene muchas dependencias superpuestas y anidadas CommonJS CJS El sistema de módulos predeterminado de Node js CommonJS CJS usa la sintaxis require para importar módulos y la sintaxismodule exports y export para exportaciones predeterminadas y con nombre respectivamente Cada archivo representa un módulo y todas las variables locales del módulo son privadas ya que Node js envuelve el módulo dentro de un contenedor de funciones Por ejemplo este módulo const PI pow Math function calculateArea radius return PI pow radius module exports calculateArea Se convierte en function exports require module filename dirname const PI pow Math function calculateArea radius return PI pow radius module exports calculateArea El módulo no solo tiene sus variables dentro del ámbito privado sino que aún tiene acceso global a exports require y module filename y dirname tienen el ámbito del módulo y contienen el nombre del archivo y el nombre del directorio del módulo respectivamente La sintaxis requerida le permite importar módulos incorporados de Node js o módulos de terceros instalados localmente ProsLas sentencias require de CommonJS son síncronas lo que significa que los módulos de CommonJS se cargan de forma síncrona Siempre que sea el único punto de entrada de la aplicación CommonJS automáticamente sabe cómo ordenar los módulos y manejar las dependencias circulares ContrasAl igual que los IIFE CommonJS no se diseñópara generar paquetes de tamaño pequeño El tamaño del paquete no se tuvo en cuenta en el diseño de CommonJS ya que CommonJS se utiliza principalmente para desarrollar aplicaciones del lado del servidor Para las aplicaciones del lado del cliente el código debe descargarse primero antes de ejecutarlo La falta de agitación de árboles convierte a CommonJS en un sistema de módulos no óptimo para aplicaciones del lado del cliente Definición de módulo asíncrono AMD Asynchronous Module DefinitionA diferencia de IIFE y CommonJS Asynchronous Module Definition AMD carga módulos y sus dependencias de forma asincrónica Con origen en Dojo Toolkit AMD estádiseñado para aplicaciones del lado del cliente y no requiere herramientas adicionales De hecho todo lo que necesita para ejecutar aplicaciones siguiendo el formato del módulo AMD es la biblioteca RequireJS un cargador de módulos en el navegador Eso es Aquíhay un ejemplo simple que ejecuta una aplicación React simple estructurada con AMD en el navegador lt index html gt lt html lang en gt lt head gt lt meta charset UTF gt lt meta http equiv X UA Compatible content IE edge gt lt meta name viewport content width device width initial scale gt lt title gt React AMD lt title gt lt head gt lt body gt lt div id root gt lt div gt lt script type text javascript src ajax libs require js require min js gt lt script gt lt script type text javascript src main js gt lt script gt lt body gt lt html gt A continuación este es el aspecto de JavaScript main jsrequirejs config paths react dist react react dom react dom dist react dom requirejs react react dom React ReactDOM gt ReactDOM render React createElement p Greetings document getElementById root Llamar a los métodos requirejs o define registra la función de fábrica la función anónima pasada como segundo argumento a estos métodos AMD ejecuta esta función solo después de que se hayan cargado y ejecutado todas las dependencias ProsAMD permite definir varios módulos dentro de un solo archivo y es compatible con navegadores más antiguos ContrasAMD no es tan popular como los formatos de módulos más modernos como los módulos ECMAScript y la definición de módulo universal Definición de módulo universal UMD Universal Module DefinitionPara las bibliotecas que admiten entornos del lado del cliente y del lado del servidor la Definición de módulo universal UMD ofrece una solución unificada para hacer que los módulos sean compatibles con muchos formatos de módulo diferentes como CommonJS y AMD AquíestáUMD en acción desde la biblioteca de desarrollo de React function root factory if typeof define function amp amp define amd Checks for RequireJS s define function Register as an anonymous module define exports factory else if typeof exports object amp amp typeof exports nodeName string Checks for CommonJS Calls the module factory immediately factory exports else Register browser globals global root self factory global React this function exports use strict Place React s module code here Si el IIFE detecta una función de definición en el alcance global y una propiedad amd en la definición entonces ejecuta el módulo como un módulo AMD Si el IIFE detecta un objeto de exportación en el ámbito global y una propiedad nodeName dentro de las exportaciones entonces ejecuta el módulo como un módulo CommonJS ProsIndependientemente de si una aplicación consume su biblioteca como un módulo CommonJS AMD o IIFE UMD verifica condicionalmente el formato del módulo que se estáutilizando en tiempo de ejecución y ejecuta código específico para el formato del módulo detectado ContrasEl código de la plantilla UMD es un IIFE de aspecto intimidante y su uso es inicialmente un desafío Sin embargo UMD en síno es conceptualmente complicado Módulos ECMAScript ESM Los módulos ECMAScript ESM el formato de módulo introducido más recientemente es la forma estándar y oficial de manejar módulos en JavaScript Este formato de módulo se usa comúnmente en aplicaciones TypeScript Al igual que CommonJS ESM proporciona varias formas de exportar código exportaciones predeterminadas o exportaciones con nombre circle jsexport function calculateArea return Math PI Math pow radius export function calculateCircumference return Math PI radius La importación de estas exportaciones nombradas por separado le dice al paquete de módulos quépartes del módulo importado deben incluirse en el código generado Se omiten todas las exportaciones con nombre no importadas Esto reduce el tamaño de la biblioteca lo cual es útil si su biblioteca se basa en algunos métodos de una biblioteca de utilidades grande como lodash Ahora en algún archivo en el mismo directorio que circle js necesitaríamos el módulo de la siguiente manera const calculateArea calculateCircumference require circle console log calculateArea console log calculateCircumference ProsLos paquetes de módulos son compatibles con ESM y optimizan el código mediante técnicas como la agitación de árboles elimina el código no utilizado del resultado final que no son compatibles con otros formatos de módulo La carga y análisis de módulos es asincrónica pero su ejecución es sincrónica ContrasEste es el sistema de módulos principales más nuevo Como tal algunas bibliotecas aún no lo han adoptado Creación de tu propia biblioteca de React JavaScriptComo puede imaginar elegir el sistema de módulos correcto se vuelve importante al crear tu propia biblioteca React Personalmente con el uso hoy en dia de herramientas como babel js podriamos trabajar con modulos de ECMAScript pero yo soy partidario de usar CommonJS en Node y ECMAScript Modules ESM en el frontend khriztianmoreno	2022-04-21 15:09:10

海外TECH	DEV Community	Machine Learning Ethics with Responsible AI	https://dev.to/integerman/machine-learning-ethics-with-responsible-ai-19c	Machine Learning Ethics with Responsible AII recently discovered Microsoft s responsible AI principles while studying for the Azure AI Fundamentals certification I found it immensely reassuring that the first thing Microsoft stressed in my studies was the importance of responsible and ethical design of artificial intelligence systems Ethics in AI is incredibly important because it can be so easy for machine learning algorithms to accidentally pick up biases that were never desired or intended What s worse is that the creators of those AI systems may not even realize that they ve created a biased system because understanding AI models can be a very difficult thing to do This content is also available in video form on YouTube The Six Principles for Ethical AI DesignLet s take a look at Microsoft s principles for responsible AI and discuss why they re so vitally important in the design development operation and sales of AI systems regardless of if you re using cloud based AI solutions or other options The principles we ll be examining are FairnessReliability amp SafetyPrivacy amp SecurityInclusivenessTransparencyAccountability FairnessThe fairness principle involves treating all classes of users fairly An AI should not discriminate against individual users based on ethnicity gender sexual orientation religion or any other factor A critical note here is that fairness is not about the intent of the designers of the system but instead about the actual behavior of the system One of the major drawbacks of AI is that it can be hard to determine why a system made a decision it did see Transparency later and so extreme care is needed to make sure that you don t feed an AI any data that may bias it against specific groups of individuals For example if an AI system for a loan application took in fields including the applicant s postal code and the only people applying from a specific postal code are people with bad credit a machine learning algorithm may learn to discriminate against individuals in that postal code Due to historic racial segregation of neighborhoods this could lead to a system overwhelmingly biased against certain groups of people Fairness requires that applications be given a diverse set of data of sufficient volume and carefully excluding any columns that might accidentally introduce bias into the system Fairness also requires that AI solutions are monitored closely for continued fairness after deployment Reliability amp SafetyReliability and safety in AI systems involves making sure the algorithm can safely handle a wide range of scenarios that may come its way Imagine you re a developer on a team working on self driving cars Your primary concern in that type of application would be ensuring the safety of the occupants of the vehicle and the other vehicles on the road You d need to test your AI in different lighting conditions weather conditions and many different areas You d need to test for situations where the roads were empty and when there were a large number of pedestrians bicyclists and other vehicles on the road Not everyone works on building self driving cars though that would be awesome but every AI system deployed needs a certain level of reliability and safety baked in If a system works fine in testing but can t keep up with sudden spikes in number of requests or is unable to reliably handle wildly different inputs in real world scenarios it does not meet the reliability and safety standards required by an artificial intelligence solution Privacy amp SecurityPrivacy and security involves ensuring that data that enters AI solutions is handled responsibly and securely In an ideal world sensitive information would not need to travel across the internet In fact this is possible in some AI solutions with JavaScript and on device machine learning frameworks available Under these scenarios sensitive data would be entered by a user processed by a stored AI model operating in the browser or on the user s device and then the sensitive data would be discarded without needing to be transmitted across the internet Additionally if an AI doesn t need sensitive information such as social security numbers names phone numbers E Mail addresses or other personally identifiable information PII it is best to exclude that information from anything sent to such an algorithm to reduce the potential for future violations However sometimes sensitive data is needed and does need to be transmitted and potentially even stored in databases The privacy and security principle involves ensuring all data that needs to be stored is stored with the appropriate level of respect and security InclusivenessInclusiveness states that artificial intelligence solutions should be for all people regardless of any disabilities or impairments Furthermore Microsoft asserts that by designing our systems for those with the most limitations we can extend those solutions to serve all other groups of people as well As someone who spent some time with paralysis a number of years ago including the inability to smile for a period of time I can relate strongly with this principle For example if an app developer used Azure s cognitive services and its Face API to make sure users were smiling when creating their profile pictures or logging in I wouldn t have been able to use the system Inclusiveness means designing your solutions with the hearing impaired mute color blind and physically disabled in mind TransparencyTransparency is an extremely interesting and compelling concern in AI systems Many machine learning solutions particularly neural nets can come to a working solution for a problem that performs well but it becomes very hard to understand how the algorithm arrived at the decisions it did The transparency principle has two components We need to be honest with our users about the potential limitations of our systemsWe need to be able to understand how our systems are working and debug their operationFor the first principle this means that we need to be transparent about the idea of potential inaccuracy inherent in machine learning solutions For example a machine learning solution that screens for an illness might need to disclose that false positives or false negatives are a potential A self driving car algorithm might need to be transparent about the conditions the system is known to be fairly reliable in but advocate for constant human monitoring and intervention or caution against certain weather conditions like fog or snow storms On the second point of transparency for debugging a machine learning algorithm to review loan applications must offer transparency to your team so that the basis for its decision making process is evident in case it is discovered to be incorrect or biased Thankfully we are making leaps and bounds on adding explainability to our machine learning models particularly in cloud hosted environments like Microsoft Azure as is illustrated by the image below depicting some critical factors of evaluating a movie classification algorithm In the above image the release month column is the most important factor for classification with Is Comedy being shortly behind it in importance We ll explore these diagrams and model explainability on Azure in future articles AccountabilityAccountability means that artificial intelligence solutions must be accountable to local state and federal authorities and relevant regulations as well as organizational leadership in the corporate world Accountability also extends to the creators of AI solutions who must ensure that their applications conform to the other principles Every system will have some risk for inaccuracy but accountability is about minimizing all possible risk and identifying and eliminating any bias in our systems Accountability reinforces the message that ethics in AI cannot be an afterthought but instead must be a constant consideration throughout the design development evaluation and operation of AI solutions ConclusionRegardless of what technologies you use and whether your AI solutions are on device or in the cloud or a combination of both the ethical design and operation of artificial intelligence solutions is mandatory AI solutions are amazingly powerful and even beautiful things but the possibility to accidentally allow bias into your systems and not even notice it needs to be under constant supervision during data acquisition cleaning feature selection and engineering model evaluation and ongoing operation of our machine learning solutions Personally I find Microsoft s principles for responsible AI to be very compelling and a good first step for any team on the ethical design of artificial intelligence What do you think What did Microsoft leave out What other frameworks or principles do you look at when designing your systems	2022-04-21 15:02:42
