海外TECH	DEV Community	Cupcakes are agile, what about you?	https://dev.to/infobipdev/cupcakes-are-agile-what-about-you-2pl9	Cupcakes are agile what about you As a foodie I don t mind hearing out some cool food references from time to time This time let me be the one to share Hopefully it s not too corny How would you create your product For quite a while now in the IT industry especially we all talk about agile no startup or modern tech enterprise ever says they do anything close to the waterfall approach we just go with the flow and use the fancy buzzwords and role titles But at the end of the day when the masks fall off are we really agile…are we even close to it Think about how do you build your product Even if it might seem agile with all the constant feedback on questions you might have for certain functionalities or modules or design perks they are often just ingredients If you choose to build that product in a way that you push all or most of the ingredients your product may be consisted of then at least don t be surprised with outcomes that might not get as you would wish for I suggest we don t commit to the entire product or project upfront Instead I suggest we focus on a single feature or value component first and measure its impact We can then always decide to do more and iterate    Peter MerholzAs Peter Merholz pointed out if you go and focus on all the ingredients you may or may not need for the final product up until the very end there is no real customer value With no customer value it is really hard to have any valuable feedback Actually most of the feedback one might get on such inquiries will be bringing more noise than useful pieces of information the team might use to improve the product because it s way too abstract in any other way Cupcakes are great Foodie reference spotted Yeah cupcakes everybody loves them we re just going to imagine they are also gluten free Cupcakes can be baked in a way to have the same base mass texture as your final shiny cake would have you can use the same filling as you would on its final form and the same icing The only things you cannot put into your cupcake to show resemblance to its fully evolved stage of that big final fancy cake is if you think of it just decorative things Find your core that part of your product that we mentioned above that single value component Find it work it out top down bake your cupcake and take it to degustation Everyone enjoyed the degustation If it worked   bingo You did all you had to do and scored a touchdown with close to zero effort now just keep repeating the steps until their final shape If it completely failed…well when you think of it   it s not that bad either You pitched your cupcake to the client an edible portion of the product something of value used a couple dozens times fewer resources than you would need to get anywhere close to getting valuable feedback in the first approach and saved yourself and your team much much much of your their precious time You can expect to receive valuable feedback because you provided something of value to the client as well So next time you start working on something you might want to scale it down Agile is not just about keeping the stakeholders in a loop and constant feedback gathering It is also about saving time and resources on trial and fail until success loops and products are about giving an actual value so scope it down and start delivering it from the very beginning of the process	2021-07-23 07:20:32
海外TECH	DEV Community	Learn this 21 JavaScript Tricks To Code Like A Pro !	https://dev.to/suhailkakar/learn-this-21-javascript-tricks-to-code-like-a-pro-p4	Learn this JavaScript Tricks To Code Like A Pro This article was first published on my own blog hereJavaScript is a programming language used primarily by Web browsers to create a dynamic and interactive experience for the user Most of the functions and applications that make the Internet indispensable to modern life are coded in some form of JavaScript While JavaScript is not the only client side scripting language on the Internet it was one of the first and it is still the most widely used Many developers believe that JavaScript is inefficient and finicky so they have made many improvements to the language over the years Here are the JavaScript tricks that makes you a JavaScript pro Use logical AND OR for conditionsvar xyz xyz amp amp runFunction is the same thing as if xyz runFunction xyz runFunction is the same thing as if xyz runFunction Avoid using for loop for arraysInstead of usingvar add for var i in arrayAdd add arrayAdd i It is better to usevar add for var i len arrayAdd length i lt len i add arrayAdd i Filter unique valuesWe can use Set to create a new array with only the unique values const array const AnotherArray new Set array console log AnotherArray Result Comment your code oftenComments are a great way to summarise a code fragment s purpose saving your time it would take to determine it on their own declaring and initialising variable xvar x Use strict mode to catch silent errorsTo opt into strict mode add the line use strict either at the top of your script section if you want the whole section to be strict or before the desired function if only certain sections should be strict Write shorter loops with array methodsInstead of usingconst prices const formattedPrices for let i i lt prices length i const price parseFloat prices i if price formattedPrices push price console log formattedPrices It is better to useconst prices const formattedPrices prices map price gt parseFloat price console log formattedPrices Empty an arrayvar someArray apple banana watermelon someArray length someArray will be equal to Generate an array of numbers with numbers from to maxvar someArray max for var i someArray push i lt max console log someArray someArray use instead of The or operator performs an automatic type conversion if needed The or operator will not perform any conversion It compares the value and the type which could be considered faster than is false is trueJavaScript is the only language that I m aware of that people feel they don t need to learn before they start using it Douglas Crockford Append an array to another arrayvar firstArray string true var secondArray anotherstring false Array prototype push apply firstArray secondArray firstArray will be equal to string true anotherstring false Don t use delete to remove an item from arrayUse splice instead of using delete to delete an item from an array Using delete replaces the item with undefined instead of the removingit from the array Instead of Usingvar items string true items length return delete items return trueitems length return console log items empty string true It is better to usevar items string true items length return items splice items length return console log items string true Rounding number to N decimal place using toFixedvar number number num toFixed console log number num will be equal to Avoid using with in your codeWhen you use with it inserts a variable at the global scope Thus if another variable has the same name it could cause confusion and overwrite the value Convert to StringTo quickly convert a number to a string we can use the concatenation operator followed by an empty set of quotation marks const number console log number Result Float to IntegerIf you want to convert a float to an integer the faster way to truncate a float to an integer using the bitwise OR operator console log console log Get the Last Item s in an ArrayThe array method slice can take negative integers and if provided it will take values from the end of the arraylet someArray string true console log someArray slice true console log someArray slice   string true console log someArray slice   string true Avoid the use of eval Useing of eval is expensive operations as each time it is called script engine must convert source code to executable code var func eval functionCodeHere Use switch case statement instead of a series of if elseUsing switch case is faster when there are more than cases and it is more elegant Avoid using it when you have more than cases Convert to Numberlet number number number console log number Comma OperatorIn JavaScript the operator is used for evaluating each of its operands from left to right and returns the value of the last operand let count let num count count console log num Use a MinifierBefore making your website live It is better to use a JavaScript Minifier to minify your code This will make your website load much faster ConclusionThere are many other tips tricks and best practices so if you have any ones to add please share it in the comment section	2021-07-23 07:05:51
海外TECH	Engadget	NASA's InSight probe reveals the first detailed look at the interior of Mars	https://www.engadget.com/nasas-insight-reveals-the-first-detailed-look-at-the-interior-of-mars-071812860.html?src=rss	NASA x s InSight probe reveals the first detailed look at the interior of MarsNASA s InSight lander arrived on Mars in to learn about its interior by monitoring quot marsquakes quot and now the project is starting to really pay off NASA has announced that researchers have mapped the red planet s interior and discovered some big surprises and major differences with Earth nbsp The map is the first ever of the interior of another planet Compared to Earth Mars has a thicker crust thinner mantle layer and a bigger less dense and more liquid core than expected That in turn suggests that Mars may have formed millions of years before our planet when the sun itself was still not fully formed nbsp quot It gives us our first sample of the inside of another rocky planet like Earth built out of the same materials but very very different quot University of Cambridge seismologist Sanne Cottaar who wasn t involved in the project told the Wall Street Journal “It is impressive Constructing a map from the limited data provided by InSight was no easy feat The probe only recorded quakes from one location and has just a single seismometer for one thing And Mars ーwhile seismically active ーdidn t have any quakes larger than around on the Richter scale nbsp ScienceStill taking that data along with planet s magnetism and orbital wobbles scientists were able to create a detailed map The planet s innermost core was found to have a diameter of around miles larger than previously thought Given the mass of the planet as a whole that implies that the iron nickel core likely contains lighter elements like sulfur oxygen and carbon nbsp The crust meanwhile was found to be very old It was also thicker in Mars southern highlands and thinner in the northern lowlands which may have hosted oceans long ago On average it s between and miles thick and split into several layers of volcanic rock The mantle between the crust and core extends roughly miles below the surface It s thinner than Earth s and has a different composition which suggests the two planets arose from different materials when they formed This “might be the simple explanation why we don t see plate tectonics on Mars ETH Zurich geophysicist and study co author Amir Khan told the New York Times nbsp The results has given scientists new insight into not just the inside of Mars but how rocky planets form in general That will help them develop new theories about planet formation that could become particularly valuable in the near future when new instruments like the James Webb Space Telescope will allow astronomers to scan exoplanets around the galaxy NASA will reveal more about its findings in a live event later today nbsp	2021-07-23 07:18:12
