海外TECH	DEV Community	Content Projection in Angular	https://dev.to/this-is-angular/content-projection-in-angular-1n9b	Content Projection in AngularToday we will learn about a very important concept called Content Projection It s very useful concept and helps to make an application dynamic Let s dive in by creating our playground first Lets create a component called my cards and use it in the app component html file Hint using the selector Now lets try out a simple exercise Add the below code in the app component html file lt app my cards gt lt span gt This is some content in between the card selector lt span gt lt app my cards gt If you open the browser to check the output you will see the text you typed in between the selector i e This is some content in between the card selector is not visible not getting displayed The output So the span element which is the child of the selector is the content and it s also the child element So if we combine both the term we get content child The span element is the content child Now as we saw earlier in the demo the content child is not getting displayed So in order to display the content child we need to project it Or in simple term we need to have a special placeholder in the child component MyCardsComponent which will catch receive the value and display it This special placeholder is ng content So now let s update the MyCardsComponent s template to have lt ng content gt lt ng content gt and now you will see the below output So what exactly happens The child content here in this case the span gets projected in the ng content So ng content acts as a placeholder Now what if you need multiple placeholders For example you will pass a content that would sit on the card header another content as the card body and another in the card footer For that we need to use something called select It is very powerful The select can accept a class id attribute or an element Confused Lets see a quick example Paste in the below code in the app component html file lt app my cards gt lt header gt Card Header lt header gt lt span id card sub header gt Card Sub Header lt span gt lt div class card body gt This is a card Body lt div gt lt footer title card footer gt Card Footer lt footer gt lt app my cards gt And in the my cards component html file i e MyCardsComponent s template file paste in the below code lt ng content select header gt lt ng content gt lt ng content select card sub header gt lt ng content gt lt ng content select card body gt lt ng content gt lt ng content select title gt lt ng content gt The output So the ️⃣first ng content has a selector which matches an element tag the header tag️⃣Second ng content selector matches an id card sub header️⃣Third ng content selector matches a class card body️⃣Fourth ng content selector matches an attribute titleThere can also be a scenario where instead of using header tag in the above example you need to use a div tag like below lt app my cards gt lt div gt Card Header lt div gt lt span id card sub header gt Card Sub Header lt span gt lt div class card body gt This is a card Body lt div gt lt footer title card footer gt Card Footer lt footer gt lt app my cards gt Then the header will not work right And suppose you don t have the option to change the card component also Then what s the solution ngProjectAs comes to the rescue Paste in the below code lt app my cards gt lt div ngProjectAs header gt Card Header lt div gt lt span id card sub header gt Card Sub Header lt span gt lt div class card body gt This is a card Body lt div gt lt footer title card footer gt Card Footer lt footer gt lt app my cards gt Here you can see the first line is the div tag And we have used ngProjectAs header In this case Angular will consider the selector as header and the output will work as it is That s all for now Hope you enjoyed reading the postIf you liked it please like ️share comment Coming up ContentChild and ContentChildren So stay tuned I will be tweeting more on Angular JavaScript TypeScript CSS tips and tricks So hope to see you there too Cheers Happy Coding	2022-01-22 18:29:37
海外TECH	DEV Community	A Step by Step Guide: The Writing Process to Use to Write Good Technical Articles	https://dev.to/the_greatbonnie/a-step-by-step-guide-the-writing-process-to-use-to-write-good-technical-articles-703	A Step by Step Guide The Writing Process to Use to Write Good Technical ArticlesA good technical writer is someone who can break down complex concepts into simple and straightforward language that is easy to understand To be able to do that you need a good writing process A good writing process will help you to Understand the topic you are writing about Know your audience Know how to structure an article This article will show you the writing process you can use to write good technical articles that clients will like and make them come for more Here are the steps we will be covering Step BrainstormingStep Preparing to writeStep Writing your first draft Step Editing and Revising Step Proofreading your final draft Step Publishing your finished work Step BrainstormingBrainstorming is where you google the topic you will be writing about Googling will help you understand and get a firmer grasp of the topic Brainstorming will be very important especially when you start getting Technical Writing work from clients Sometimes a client will ask you to write about a topic you are unfamiliar with Being unfamiliar with a particular topic can be pretty intimidating and overwhelming When you get yourself in such a situation you only need two things Knowing how to google Willingness to learnFor example in my first paid Technical Article I was asked by a client to write about How to get Stripe payment data load the data into a database and visualize the data using graphs or charts I didn t know how to do that but I figured things out since I knew how to google and I was willing to learn Step Preparing to writePreparing to write is where you put together all the information and ideas you collected during the brainstorming stage You then use that information to develop the structure or outline of the article An outline in simple terms is basically a skeleton of a finished piece of writing that maps the topics you will cover in an article An outline provides a structure that helps ensure your ideas flow logically and clearly Here is what an outline of an article looks like TitleIntroductionBodyConclusionA title should be a headline that demands attention and should have keyword combinations that reflect what the article is about The introduction should describe the problem and the solutions the article will cover Ensure that the introduction lets the reader know what the article is about In the body part of the article describe the problem and the solution in detail Try to tell a story The story should keep the reader engaged at every step Make a list of your main points Then progress from one point to another logically to lead to a conclusion The conclusion should essentially include a summary of all the main points mentioned in the body NB Preparing to write is also the coding stage Most of the technical articles you will write will need you to work on a project then write about the process Step Writing your first draftWriting your first draft is when you write the words on the page Here you should focus only on writing and not on grammar or writing a good piece ready to publish You will do that during the editing stage Use the outline you created in the preparing to write stage to build your draft sentence by sentence and paragraph Step Editing and revisingEditing and revising is the stage where you shape the completed rough draft into a final draft Make sure that you take a break between writing and editing Taking a break will enable you to view your work with fresh eyes One way to quickly find areas to make your writing stronger is to read it aloud By listening to the rhythm of your writing you can hear Words that feel out of place Awkward transitions Redundant phrasesInconsistent tenses and tonePoints where you need more details One tool that will come in handy in this stage is Grammarly Step Proofreading your final draftProofreading your final draft is the stage where you have finished your writing but you are not quite ready to publish it or hand it to your client Here you go through your article to catch Any spelling mistakesGrammar errorsTyposFormatting errorsIncorrect structure or syntax Step Publishing your finished workPublishing your finished work is the stage where you hand your work to the client or publish the work on your blog or on any blogging platforms like Dev ToHash nodeMedium ConclusionWriting an excellent technical article that solves a problem for the reader is all about using the proper writing process If you have any questions concerning Technical Writing feel free to reach out to me and I will be more than willing to help	2022-01-22 18:14:31
海外TECH	DEV Community	How To Stay Curious as a Coder	https://dev.to/somacdivad/how-to-stay-curious-as-a-coder-510b	How To Stay Curious as a CoderCover photo by Wil Stewart on Unsplash It s easy to be complacent about curiosity Our lives are filled with stress We craft routines around that stress Sometimes those routines turn life into an inescapable turnstile It isn t easy to be curious when your life depends on keeping the wheel turning I spend a lot of my time solving problems with Python Problem solving demands creativity Curiosity breeds creativity The demand for creative software solutions is constant but curiosity comes and goes When your curiosity wanes don t resign yourself to the idea that some people are naturally more curious about things and that perhaps you re not one of them Curiosity is not an immutable trait You can learn how to be more curious How To Cultivate CuriosityCuriosity is contagious Follow curious people and you ll likely catch the bug Once your mind is infected with a framework for curiosity you instinctively apply that framework to everything Mystery is the key to curiosity Embrace feeling puzzled because puzzles are everywhere Question absolutes and axioms even the ones in this article Devise experiments to test premises Learn to recognize when your curiosity ebbs I know that my curiosity is critically low whenever I stop reading consistently I m not talking about reading code   I mean reading anything It s a case of intellectual malnutrition and the cure is a content rich diet Consume Content VoraciouslyGet into a habit of passive consumption Listen to podcasts during your commute or household chores Watch documentaries during your lunch break If your mind wanders let it Don t focus on one topic A diverse content diet is more likely to reveal a mystery that stirs you Actively consume content about mysteries that particularly draw your attention Read long form articles and books Listen intently and take notes But refrain from forcing yourself into active consumption Forced activity stifles joy Key Takeaway Consume content the same way a lion consumes prey Spend most of your time passively observing the stream of information before you When hunger strikes ferociously stalk your curiosity Dive Deeply Into Things That Interest You Right NowUnlike diets that nourish our bodies a curiosity inducing content diet has no plan and no schedule Explore topics haphazardly but also explore them deeply Don t delay your curiosity Pursue topics that interest you right now Get lost in rabbit holes but avoid ones generated algorithmically Algorithms have a knack for surfacing similar content Actively search for answers to questions that arise Key takeaway Curiosity moves like water pulled upwards through a tree s xylem by capillary action Surrender to the twists and turns Allow the final destination to be a mystery Embrace Learning as a ConversationCuriosity is a tug of war between selfishness and humility You re compelled by a primal urge to know more Yet learning requires you to expose a gap in your understanding to recognize that there is still more to be known Learning is a conversation Participate in that conversation Ask questions A good question synthesizes existing knowledge and addresses an acknowledged gap in understanding ️Key takeaway Curiosity is like a REPL Read Consume content Evaluate Think critically ask questions and discover solutions Print Share what you ve learnedLoop Interpret feedback and start over How To Practice Curiosity as a CoderGetting better at being curious requires practicing curiosity Fortunately coding is full of puzzles There are packages and tools to discover languages to learn and implementation details to explore Here are two techniques I ve used to practice curiosity while coding Use Things In Ways They Weren t Intended to Be UsedPush boundaries and perform experiments I once worked as a programmer for a commercial audio visual installation company On one job we installed a distributed video switching system controlled by an app The app sent TCP packets from an iPad to a network switch and used VLAN untagging to connect video receivers on the network to broadcasts streamed by transmitters The app was incompatible with the latest switch firmware The IT department refused to downgrade the firmware and the app developer couldn t deliver a patch until well after the project deadline But I could configure the app to send commands to any IP address I could write a TCP server to accept commands from the app convert them to the network switch s protocol and forward them to the switch I needed a machine to host the script The audio processing unit APU was a Linux box with plenty of storage and memory Installing a custom script would void the warranty The APU was programmed by a drag and drop visual coding interface One of the available blocks could run Lua scripts inside the application s sandbox But could a script running in the sandbox receive commands from the app and communicate with the network switch There were no documented restrictions so I ran an experiment It worked Even better script blocks automatically started whenever the APU booted Video switching worked effortlessly even after reboots from power outages and other incidents My curiosity paid off We completed the job on time My discoveries created new solutions for clients and spawned internal tools that saved time and money on installations Try To Break ThingsDestruction can be productive I enjoy finding ways to break a language It isn t about finding bugs It s about finding code examples that exhibit surprising behavior It always starts with a question How does a Python set determine if two objects are distinct Knowing where to start looking for answers is a crucial skill The Python docs on sets are pretty good Oh ok Sets use an algorithm that checks if two objects have the same hash value and compare equal to each other If both checks are true then those objects are indistinguishable from each other and the set can only contain one of them A little bit of knowledge opens the door to new questions Can you trick a set into thinking two different objects are nondistinct Now there s a fun little puzzle Think about it An integer hashes to its value You can control a custom object s hash value with the  hash method That means you can create an object that hashes to the same value as the integer class NotOne def hash self return To confuse a set into thinking NotOne instances are equal to you need them to compare equal to You can make NotOne objects compare equal to any object by implementing an  eq method that always returns True class NotOne def hash self return def eq self other return TrueNow see what happens when you create a set containing and an instance of NotOne gt gt gt n NotOne gt gt gt Create a set S containing and n gt gt gt S n gt gt gt S only contains gt gt gt S gt gt gt But somehow n is in S gt gt gt n in STruen is very much a distinct object from n isn t even a number It doesn t support arithmetic operations But you ll never be able to put n and in a set together because they fail to meet a set s criteria for distinctness It feels weird that any set containing also contains n That s pretty weird I wonder if there s a way to trick a set into thinking two nondistinct objects are distinct from each other For such a thing to be possible requires an object that doesn t compare equal to itself If you ve ever worked with IEEE NaN objects before you know they fit the bill What happens when you try to put several NaN values into a Python set Let s find out gt gt gt S float nan float nan float nan gt gt gt S nan nan nan Ok that is weird But surely you can verify that the set contains a NaN object Right Behold gt gt gt float nan in SFalseI love examples like this In all honesty nothing is broken   except maybe my brain for a little bit Seeking out and understanding examples like these strengthens your intuition about code and surfaces new ideas for solving problems Where To Go From HereStart practicing curiosity today Ask more questions and do more experiments Be thankful that it s impossible to know everything There s always a new puzzle to be solved There are always new things to wonder about Continue LearningHere are five resources to help you learn more about the science of curiosity and cultivate more of it for yourself How to become more curious by Scott H Young More on the science of curiosity and tips for cutlivating more of it This is your brain on curiosity by Matthias Gruber Explore curiosity s role in how well we remember information The psychology and neuroscience of curiosity by Celeste Kidd and Benjamin Y Haden A
