海外TECH	DEV Community	External code in Unreal Engine game source	https://dev.to/goals/external-code-in-unreal-engine-game-source-414o	External code in Unreal Engine game sourceIntroductionAs many game developers know the Git MB files size limit renders vanilla Git useless For us LFS did not seem like a viable option we may post our full report regarding selecting version tracker later and we ended up gong with Plastic SCM So what we have now is A game build on Unreal Engine We are using the source version of the engine as we need to touch engine code Full game and engine source as well as game data stored in a Plastic SCM repository All cloud services backend code and shared code stored in our GitHub repository To be able to work with faster iteration times outside the engine use the Git workflows and tool sets and potentially share code with other Goals services we have introduced the External Packages Workflow In a nutshell it is a GitHub repository inside the Goals game source and it allows for a couple of workflows Iterate rapidly on a library and its tests outside the engine source Iterate on a library committing to the GitHub repository but while testing it as part of the game source Iterate on a library when using it as part of another goals service Allow packages to be both Bazel packages and Unreal source at the same time without interfering with each other For the remainder of this article I will use the Goals game ai library as an example It could also be used for instance for shared Protobuf definitions files or something similar The key is that you can put anything there that does not interfere with Unreal build system Defining which packages to useSince there was no natural place to add a list of external packages that we needed to use we introduced the Packages goals file that lives in the root of the Game source This is a text file with a pretty self explanatory syntax Defines which external Goals packages should be added to the source If the Commit hash releaese is omitted latests will be fetched Format Package name Remote git url Commit hash Release tag Game AIgame ai adedbaccceccaWrapping Setup sh batTo achieve this without adding an extra thing you have to do each time you sync we introduced GoalsSetup sh bat What GoalsSetup does is Wrap the Setup sh bat files shipped with Unreal and only run it if needed Check if there are any missing external code repositories missing as defined by the Packages goals file and if there are fetch or update Check if one of the external repositories have been touched locally i e git status porcelain and if it has leave it alone So as a coder the only thing you have to do after you sync the main game repository is run GoalsSetup and everything should be dandy It is our goal to not have any other dependencies that are needed on your machine apart from the ones dictated by working with unreal which is essentially a compiler Hooking into Unreal build systemThe easiest way to hook into unreal build system is to look at all external packages as one Packages module This way unreal build system can parse the source for the needed files and add them as dependencies for the game So create a new module by adding a build file in your source For example Packages Build cs using UnrealBuildTool public class Packages ModuleRules public Packages ReadOnlyTargetRules Target base Target PCHUsage PCHUsageMode UseExplicitOrSharedPCHs PrivateDependencyModuleNames AddRange new string Now in your game add this module as a dependency For example in Game Build cs using UnrealBuildTool public class Game ModuleRules public Game ReadOnlyTargetRules Target base Target PCHUsage PCHUsageMode UseExplicitOrSharedPCHs PublicDependencyModuleNames AddRange new string Packages Now each time you build your game project the source of the Packages module will be parsed and needed files added to the project Here is what it could look like in your source Note that the external package game ai has some Git and Bazel related files in it but that is fine And now for each package we add to the Packages goals text file a new directory is created on the side of the game ai directory above and its files included in the game build Left to do and caveatsWe still need to be able to handle including more complex packages This could be for instance packages with source files that should not be included test files or files that are disruptive to the Unreal build system This could be handled in Packages Build cs above by excluding certain directories Maybe ones the include the word test for example See how this is done in for instance RuntimeMeshLoader If we want to include packages that depend on other packages we would have to make sure the include paths are the same and the libraries available but ideally all the external packages are atomic and do not rely on other things	2022-02-24 14:30:07
海外TECH	DEV Community	Tutorial: build DApp with Web3-React and SWR	https://dev.to/yakult/tutorial-build-dapp-with-web3-react-and-swr-1fb0	Tutorial build DApp with Web React and SWRIn the tutorial build DAPP with hardhat React and Ethers js we connect and interact with the blockchain using ethers js directly It is OK but there are too many works need to be done by ourselves We would rather use frameworks to help us with three jobs maintain context and connect with blockchain connect to different kinds of blockchain providers manage query to blockchain more efficiently Web React a connecting framework for React and Ethereum can help us with job amp Web React is an open source framework developed Uniswap engineering Lead Noah Zinsmeister We will focus on job SWR can help us read blockchains more efficiently SWR stale while revalidate is a library of react hooks for data fetching I learn SWR from the Consensys tutorial by Lorenzo Sicilia How to Fetch and Update Data From

海外TECH	DEV Community	Ownership and borrowing. Rust Tutorial:4	https://dev.to/dumboprogrammer/ownership-and-borrowing-rust-tutorial4-2hik	Ownership and borrowing Rust Tutorial Understanding OwnershipOwnership is Rust s most unique and famous feature and has deep implications for the rest of the language It enables Rust to make memory safety guarantees without needing a garbage collector so it s important to understand how ownership works In this blog we ll talk about ownership as well as several related features borrowing slices and how Rust lays data out in memory What Is Ownership Ownership is a set of rules that governs how a Rust program manages memory All programs have to manage the way they use a computer s memory while running Some languages have garbage collection that constantly looks for no longer used memory as the program runs in other languages the programmer must explicitly allocate and free the memory Rust uses a third approach memory is managed through a system of ownership with a set of rules that the compiler checks If any of the rules are violated the program won t compile None of the features of ownership will slow down your program while it s running Because ownership is a new concept for many programmers it does take some time to get used to The good news is that the more experienced you become with Rust and the rules of the ownership system the easier you ll find it to naturally develop code that is safe and efficient Keep at it When you understand ownership you ll have a solid foundation for understanding the features that make Rust unique In this chapter you ll learn ownership by working through some examples that focus on a very common data structure strings The Stack and the Heap Many programming languages don t require you to think about the stack and the heap very often But in a systems programming language like Rust whether a value is on the stack or the heap affects how the language behaves and why you have to make certain decisions Parts of ownership will be described in relation to the stack and the heap later in this chapter so here is a brief explanation in preparation Both the stack and the heap are parts of memory available to your code to use at runtime but they are structured in different ways The stack stores values in the order it gets them and removes the values in the opposite order This is referred to as last in first out Think of a stack of plates when you add more plates you put them on top of the pile and when you need a plate you take one off the top Adding or removing plates from the middle or bottom wouldn t work as well Adding data is called pushing onto the stack and removing data is called popping off the stack All data stored on the stack must have a known fixed size Data with an unknown size at compile time or a size that might change must be stored on the heap instead The heap is less organized when you put data on the heap you request a certain amount of space The memory allocator finds an empty spot in the heap that is big enough marks it as being in use and returns a pointer which is the address of that location This process is called allocating on the heap and is sometimes abbreviated as just allocating Pushing values onto the stack is not considered allocating Because the pointer to the heap is a known fixed size you can store the pointer on the stack but when you want the actual data you must follow the pointer Think of being seated at a restaurant When you enter you state the number of people in your group and the staff finds an empty table that fits everyone and leads you there If someone in your group comes late they can ask where you ve been seated to find you Pushing to the stack is faster than allocating on the heap because the allocator never has to search for a place to store new data that location is always at the top of the stack Comparatively allocating space on the heap requires more work because the allocator must first find a big enough space to hold the data and then perform bookkeeping to prepare for the next allocation Accessing data in the heap is slower than accessing data on the stack because you have to follow a pointer to get there Contemporary processors are faster if they jump around less in memory Continuing the analogy consider a server at a restaurant taking orders from many tables It s most efficient to get all the orders at one table before moving on to the next table Taking an order from table A then an order from table B then one from A again and then one from B again would be a much slower process By the same token a processor can do its job better if it works on data that s close to other data as it is on the stack rather than farther away as it can be on the heap Allocating a large amount of space on the heap can also take time When your code calls a function the values passed into the function including potentially pointers to data on the heap and the function s local variables get pushed onto the stack When the function is over those values get popped off the stack Keeping track of what parts of code are using what data on the heap minimizing the amount of duplicate data on the heap and cleaning up unused data on the heap so you don t run out of space are all problems that ownership addresses Once you understand ownership you won t need to think about the stack and the heap very often but knowing that the main purpose of ownership is to manage heap data can help explain why it works the way it does Ownership Rules First let s take a look at the ownership rules Keep these rules in mind as we work through the examples that illustrate them Each value in Rust has a variable that s called its owner There can only be one owner at a time When the owner goes out of scope the value will be dropped Variable Scope Now that we re past basic Rust syntax we won t include all the fn main code in examples so if you re following along make sure to put the following examples inside a main function manually As a result our examples will be a bit more concise letting us focus on the actual details rather than boilerplate code As a first example of ownership we ll look at the scope of some variables A scope is the range within a program for which an item is valid Take the following variable let s hello The variable s refers to a string literal where the value of the string is hardcoded into the text of our program The variable is valid from the point at which it s declared until the end of the current scope Listing shows a program with comments annotating where the variable s would be valid s is not valid here it s not yet declared let s hello s is valid from this point forward do stuff with s this scope is now over and s is no longer valid A variable and the scope in which it is validIn other words there are two important points in time here When s comes into scope it is valid It remains valid until it goes out of scope At this point the relationship between scopes and when variables are valid is similar to that in other programming languages Now we ll build on top of this understanding by introducing the String type The String Type To illustrate the rules of ownership we need a data type that is more complex than those we covered before The types covered previously are all a known size can be stored on the stack and popped off the stack when their scope is over and can be quickly and trivially copied to make a new independent instance if another part of code needs to use the same value in a different scope But we want to look at data that is stored on the heap and explore how Rust knows when to clean up that data and the String type is a great example We ll concentrate on the parts of String that relate to ownership These aspects also apply to other complex data types whether they are provided by the standard library or created by you We ll discuss String in more depth in Chapter We ve already seen string literals where a string value is hardcoded into our program String literals are convenient but they aren t suitable for every situation in which we may want to use text One reason is that they re immutable Another is that not every string value can be known when we write our code for example what if we want to take user input and store it For these situations Rust has a second string type String This type manages data allocated on the heap and as such is able to store an amount of text that is unknown to us at compile time You can create a String from a string literal using the from function like so let s String from hello The double colon operator allows us to namespace this particular from function under the String type rather than using some sort of name like string from We ll discuss this later This kind of string can be mutated let mut s String from hello s push str world push str appends a literal to a String println s This will print hello world So what s the difference here Why can String be mutated but literals cannot The difference is how these two types deal with memory Memory and AllocationIn the case of a string literal we know the contents at compile time so the text is hardcoded directly into the final executable This is why string literals are fast and efficient But these properties only come from the string literal s immutability Unfortunately we can t put a blob of memory into the binary for each piece of text whose size is unknown at compile time and whose size might change while running the program With the String type in order to support a mutable growable piece of text we need to allocate an amount of memory on the heap unknown at compile time to hold the contents This means The memory must be requested from the memory allocator at runtime We need a way of returning this memory to the allocator when we re done with our String That first part is done by us when we call String from its implementation requests the memory it needs This is pretty much universal in programming languages However the second part is different In languages with a garbage collector GC the GC keeps track of and cleans up memory that isn t being used anymore and we don t need to think about it In most languages without a GC it s our responsibility to identify when memory is no longer being used and call code to explicitly return it just as we did to request it Doing this correctly has historically been a difficult programming problem If we forget we ll waste memory If we do it too early we ll have an invalid variable If we do it twice that s a bug too We need to pair exactly one allocate with exactly one free Rust takes a different path the memory is automatically returned once the variable that owns it goes out of scope Here s a version of our scope example from Listing using a String instead of a string literal let s String from hello s is valid from this point forward do stuff with s this scope is now over and s is no longer valid There is a natural point at which we can return the memory our String needs to the allocator when s goes out of scope When a variable goes out of scope Rust calls a special function for us This function is called drop and it s where the author of String can put the code to return the memory Rust calls drop automatically at the closing curly bracket Return Values and ScopeReturning values can also transfer ownership Listing shows an example of a function that returns some value with similar annotations as those in Listing Filename src main rs fn main let s gives ownership gives ownership moves its return value into slet s String from hello s comes into scopelet s takes and gives back s s is moved into takes and gives back which also moves its return value into s Here s goes out of scope and is dropped s was moved so nothing happens s goes out of scope and is dropped fn gives ownership gt String gives ownership will move its return value into the function that calls itlet some string String from yours some string comes into scope This function takes a String and returns one fn takes and gives back a string String gt String a string comes int scopea string a string is returned and moves out to the calling function Transferring ownership of return values The ownership of a variable follows the same pattern every time assigning a value to another variable moves it When a variable that includes data on the heap goes out of scope the value will be cleaned up by drop unless ownership of the data has been moved to another variable While this works taking ownership and then returning ownership with every function is a bit tedious What if we want to let a function use a value but not take ownership It s quite annoying that anything we pass in also needs to be passed back if we want to use it again in addition to any data resulting from the body of the function that we might want to return as well Rust does let us return multiple values using a tuple Filename src main rs fn main let s String from hello let s len calculate length s println The length of is s len fn calculate length s String gt String usize let length s len len returns the length of a String s length Returning ownership of parameters But this is too much ceremony and a lot of work for a concept that should be common Luckily for us Rust has a feature for using a value without transferring ownership called

海外TECH	DEV Community	It *IS* possible to get a voice here! [tips to grow on DEV.to + a mini rant!]	https://dev.to/inhuofficial/it-is-possible-to-get-a-voice-here-tips-to-grow-on-devto-a-mini-rant-27n6	It IS possible to get a voice here tips to grow on DEV to a mini rant I was reading a post about how hard it is to gain traction on DEV a couple of days ago go give it a read and see if you feel the same way or not It s impossible to get a voice in here Rasmus Schultz・Feb ・ min read meta I found it interesting as lots of the comments agreed and I too used to feel the same way and even catch myself feeling that way now about some of the points raised so I thought I would share my thoughts on how to grow your engagement anywhere but mainly on DEV hopefully I can give some motivation to those who find themselves lost in a sea of voices and are feeling like you will never gain traction And just to show I kind of know what I am on about views post reactions followers posts comments yeah those who know me know I am opinionated And that was in months as I haven t released much this year I have been writing just building up a buffer you will see me back in full force in March Anyway with the humble brag out of the way here are my tips and if you fancy it a rant at the end on content creation and my views on the frustration many of us experience Enjoy Consistency is keyIt doesn t matter if you are trying to feed the beast that is Twitter or writing once a month as a hobby on DEV consistency is the number priority What I say to a lot of new writers content creators is to work out how much content you think you can create in a week then halve it It is much better to release an article regularly every or weeks than it is to release sporadically I should know I was guilty of this People quickly pick up on patterns even subconsciously so if you post at a certain time at a regular interval people will start anticipating your articles Know what your goals are and write accordinglyA lot of new writers want views There is nothing wrong with that in fact you get a lot of people advising just write what you want to write Those people have forgotten the frustration of releasing an epic piece of content and getting views Something you have poured your blood sweat and tears into over numerous hours or even days and crickets So what do we do One for them one for youYet again I made this mistake and certainly hurt my early engagement I wrote what I wanted to write Instead I would recommend that if you are a new writer who wants to grow and still write about what interests you to write one for them a pandering article more on that in a second and one for you something you are passionate about but it might be a bit too niche for the platform So what is a pandering article what will get engagement on DEV Anything for beginners and code newbies and anything JavaScript specifically React Or listicles everyone loves a amazing tips listicle as it is low effort to read and you might learn something I may not like these kinds of articles but they garner engagement and followers and followers and engagement means growth Also don t be fooled that just because people click on these low brow articles they won t engage with your more complex stuff they will generally people will engage with your content once they follow you and that is where the true and meaningful engagement starts to happen Quantity firstYet again this is a beginners guide to growth Here is a little secret nobody will care what you write or remember your name for the first few months of writing you need to build a reputation and earn the right to expect people to invest time consuming your content It might seem like a bad thing but it is actually a great thing You can produce lower effort posts in higher quantities and get those all important early eyeballs The trick is to produce quality quantity and that takes practice And how do we practice By writing of course So while you are starting out just practice writing structuring your content to make it easy to consume etc You are aiming for half decent articles as quickly as possible for them and for you Don t worry about perfection early on just get your points across and make sure they add value in some way yes even a listicle can add value if you put in a tiny bit of effort This gives you a good base to grow from and means that when people discover you they can see that you have plenty to say Then once you have a base you can put more time into crafting higher quality content as you will get more views so you worry about that less As long as you stay on topic you will not lose many followers Plus this early stage of getting to critical mass will help you hone your writing style and structuring articles etc I mentioned quality quantity if you want to see an example of quality quantity check out ltag user id follow action button background color cbba important color cddd important border color cbba important Chris BongersFollow Looking to get into development As a full stack developer I guide you on this journey and give you bite sized tips every single day Chris is a content machine an article every single day but also writes very well That is why you should just write Chris s writing improved with effort and repetition to the point now where you would be hard pressed to find a flaw in any of his work If you look at Chris s early writing it wasn t raw talent although he certainly has some of it but repetition and practice that turned him into such a great writer Note I am not suggesting you release as much content as Chris or even that you should consider putting that kind of pressure on your content creation Chris is a bit of a unicorn just do what you feel you can do comfortably and enjoy yourself Engage with a communityLook you might be lucky and get a mega viral article in your first week on DEV I can tell you that it is unlikely to happen In fact I have never had a single article break k views No instead I engaged with other authors You see authors want that engagement it is one of the reasons people write to make connections So if you are the one engaging with their content they are far more likely to check out your profile and see that you produce content too Additionally it gives you a quick way to get more eyeballs on what you have to say For example Here is what many would call a low effort post What are your tips for an effective developer resumé Ben Halpern・Jan ・ min read beginners discuss career resume And they are right the post itself would not have taken Ben long to write and it got a lot of engagement But bear in mind that Ben has released loads of different types of content in various formats nearly all of it super high quality he has earned high engagement through consistent effort and that is what you need to do Anyway the point wasn t the post itself it was my comment there likes on a comment that is more than most of my articles I can tell you because I watch my notifications carefully I got about followers from that one comment it is a rough guess but I see a like from someone then a follow immediately after plus a couple of article likes from them and I can guess that comment was the discovery point of my work But for the other comments they may only get like from the post author But that post author if I comment on their stuff often will likely follow me They may even mention me in their article and get more some views if I have written something relevant Hell if you comment often enough and people start to recognise you as someone who contributes to a particular subject you might even get summoned to comment This happens to me on accessibility articles quite often someone will me to come and check the accuracy of an article You don t think that would happen if I just wrote an article every months and didn t engage do you It all takes effort and time in fact if you look at my comments you will see I have written essays in some of them I want to add value in my comments and by adding value I gain engagement it is a win win Also I like commenting on articles just to show support as a fellow author Writing takes effort with very little reward at first I am now at the stage I get paid to write and job offers it took time so don t underestimate how much of a boost even a single comment can give an author especially in the dark days of engagement tumbleweed posts Also if people take the time to comment on your article respond to them and put effort into your responses engagement works both ways and you have to earn follows Quick fire round tips and tricksThis article is getting long so here are a few tips that don t need as much detail people have written about extensively so I don t need to cover the same ground just as an interlude Learn to structure articlesUse proper headings lists etc Your goal is to make content easy to skim as well as read cover to cover But more than that it makes your articles more accessible and rank better for SEO learn to use HTML and markdown properly Here are some tips to write better contentBuild a social media followingI literally just turned up my Twitter game and will ramp up even more when I start releasing articles again Social media gets you a few early eyeballs on your articles Those early likes and unicorns make the article appear further up the feed so you get more likes etc I made the mistake of only building a following on one platform recycle content onto other platforms they all feed each other Make an engaging coverYour cover image will show on social media shares and in the timeline if you are lucky Make it engaging and relevant I cheated and just created a standard template for mine branding is important too But if you don t want to do that pick an interesting image or a GIF if appropriate visuals get more engagement Write in conversational styleWrite to the person reading your article you we us as if you are chatting with them it will increase engagement Ask for follows and sharesI made this mistake basically this whole article is don t do what I used to do if you want followers ask for them Just a simple call to action at the end of your article with what you want people to do Follow you share on social media etc etc Also try and give them a reason I write every week about XXX follow me so you don t miss out Recycle contentWriting content takes time and effort So recycle it Pick out key sentences and tweet them create an infographic if appropriate etc The more different mediums you can create your content in the better Put time into promotionAnother one of my mistakes seeing a pattern here Don t release content and expect it to magically go viral Make it happen In fact I have changed my whole release schedule so of my time is spent on promoting what I write and building connections with people who might enjoy my content promote it naturally Build it and they will come is a complete myth shout about it and grow is what I say A dirty little secretHere is a tip that is as close to a growth hack as you will get from me Heart unicorn and bookmark your own article and leave a comment on it the second your publish It helps your feed position it makes the article more attractive in the feed people are more likely to skip your article if it has no reactions and it gives you a tiny boost It feels a bit weird at first but for the sake of seconds it is worth it OK did you enjoy that interlude Back to the main tips Develop your tone of voice I am or was recent events mean those are not going to happen here on DEV anymore the angry rants person I developed a writing style that worked for me I showed some personality and you should too Whether that is with comedic GIFs please don t overdo it emojis same again a couple is fine jokes or dark humour not suitable for DEV find what works for you People read your content as much for your writing style as they do for your content People also read your content because they get to like you as a person and want to support you Make it interesting make it engaging give people a reason to come back for more and a reason to read your stuff over the other articles about the same subject Tags matter a lotI know DEV are trying to improve their feed but it will nearly always revolve around tags So if you write in a quiet tag be prepared for fewer views I write in ay often I always expect my articles there to perform worse than articles in javascript Going back to the one for them method write articles that fit with popular tags and use those tags JavaScript Beginners Tutorial CSS React they all perform well Oh and for nearly any article the webdev tag is likely to fit so use that as a fall back Take some time to look at the tags page they are ordered by popularity well number of posts which indirectly affects the people who read here and therefore content that will perform well is popular Unless you are really struggling to justify it try and use all tags you are allowed to add to an article and try and go for the more popular ones without just choosing randomly find the balance My personal take on DEV content creation and the frustrations of growth my turn to rant Note the article is over I just felt like ranting on this point and my personal views I rambled a bit but I want to leave it in and unedited as it gives you an accurate picture of my thought process Please do not read this bit if you are a person who doesn t cope well with strong opinions that differ to your own or are critical of your views instead jump down to the comments if you want and share some of your tips as I would love to hear them My rant Look we can all point fingers I have done it many times in the past but overall you can t blame DEV for your own failings That is a harsh truth but every time someone says DEV is not the place to grow or why bother writing decent content as it gets no engagement etc what they are actually saying is it didn t work for them with the way they approached it Trust me I have said it I still catch myself comparing my article s number of likes to that of a minute top productivity apps post I share the same frustrations I am one of the first to see some grifter writing listicles each week and getting thousands of views and feel myself getting annoyed But it is only when I look inward and see why I am not creating the same content as them then look outward and see why creating that type of content works so well that I can safely say I am the problem Is this what growing as a person looks like Am I finally maturing I doubt it To show you what I mean let s take the DEV feed It certainly does promote low quality crap too often So that is obviously DEVs fault right Right Well if you take a step back you realise that any algorithm will be influenced by what people want to read or at least any algorithm designed to grow a site It isn t DEVs fault that VS code plugins you have to use right now gets thousands of upvotes while a monster article on accessibility only gets a few hundred Digital Accessibility ay tips and tricks InHuOfficial・Jul ・ min read webdev html ay beginners You want high effort It took over hours You want quality Pretty sure it delivered It still did not perform well and that is just unfair surely Don t get me wrong it is top for ay for the year so it did OK but I would have expected more than views on a piece like that But is that just an unrealistic expectation Almost certainly yes This is where you need to take a step back It certainly isn t DEVs fault that listicles do well I am aware that article is technically a listicle but you hopefully know what I mean and long form content doesn t it is all about interests and attention spans etc DEV certainly can t fix that It also isn t DEVs fault that accessibility is still a secondary subject in the Developer community so doesn t have the same interest level It also isn t DEVs fault that I expected a lot more views No it is my fault I want to write about those things that are less popular I want to write long form content fewer people want to read that stuff And I might add despite the moaning it does not matter that it got low views really it got high engagement per view and helped people the views are just vanity making a difference even to just one person is what matters When you start looking at these things you start to consider things like the fact that some people don t have time to read your well crafted long form article They may be waiting for a train or eating their breakfast while doom scrolling social media feeds They might have just minutes to read something anything so a listicle will do and deliver on their expectations of time required or effort required to read it A minute read time article is not going to suit what they need This probably answers why questions do well people can start forming their thoughts on a question instantly scan read the responses and get loads of hopefully differing opinions in just a few seconds It adds value to their day and fits their current needs We can take this further as to why certain content performs better than other content The reason you get more comments on a quick question that took seconds to post rather than a long article that took hours is actually quite straight forward People write comments to share an opinion if you ask a question or make a bold statement it invites opinions So of course you will get more comments on an article like that and it will do better in the feed as comments make up part of the ranking algorithm But with all that being said there is a key factor that is less tangible does asking questions and creating listicles help your personal brand does it help build up your authority in a subject Probably not Long term that personal brand value does start to add up and results in opportunities and meaningful conversations If that is what you really want from your writing then focus on that and ignore the numbers At the same time don t see it is a bad thing asking questions and writing quick articles see it as an opportunity to grow quickly and establish a base the one for them Take the time to engage with some stuff you might see as low effort you will be surprised at the exposure you can gain for your high effort work just from participating in things that others find interesting and throwing your thoughts into the mix It took me a long time to realise I am a slow learner just because I want in depth and high quality pieces doesn t mean that everybody does I realised I should not hate on people who write listicles they are giving the people what they want Creating content takes effort even low effort content is someone sharing things with and adding things to the world I have infinitely more respect for someone who creates rather than someone who purely consumes I also do not know their personal circumstances Are they short on time and that is all they have time to create Is English a second language so listicles with less text and more graphics is in their comfort zone etc They may create that content because that is all they can create at the moment due to their own circumstances Who am I to criticise even though I do but that is my character flaw All I wish is that we could move the needle a little encourage people to engage with high effort content more Give those authors who add depth to subjects and answer those tougher questions the exposure they deserve for their effort DEV are working hard to do that and I will defend their efforts to try and move that needle in what is an almost impossible task And that is from someone who often clashes with the DEV team due to our differing ideologies Will low effort short form content ever stop cluttering your feed Given the rise of TikTok YouTube shorts twitter etc you have to take a step back and realise people like quick and short content things that are easy to consume things that are low risk do I want to read a minute article from an unknown author that might be full of errors vs a second video that may also be full of errors but I have invested far less time in Long form content is a harder thing to sell in a fast paced and over crowded space so you need to be prepared to play the long game if you want to write high effort pieces all the time I think low effort content is going to be in a feed anywhere that allows people the freedom to post without an editorial process You just have to learn to live with that and the by product that it makes it harder to get noticed in the noise So after all of that I suppose the real question is are you willing to play the game a little bit and pander Create the content people want to see and casually engage with in exchange for more meaningful engagement on your more thought provoking higher quality pieces in the future I think the answer is yes you should The short term pain of writing things that may not be for you is more than offset by the growth and the small platform it allows you to build for yourself In summary if you aren t growing it is your fault it is down to choices you make That is not saying those choices are bad but you certainly need to put in the effort and adjust your content creation if views and growth are your primary concern Once you reach a certain size pivot to writing more and more content you want to see you should hopefully have the community around you at that point to support it Thanks for reading please let me know your thoughts and any tips you have for growth in the comments Oh and don t forget to give this article a and a it really does help and is appreciated	2022-02-24 14:08:12

海外TECH	Engadget	'OlliOlli World' is a great Switch experience, despite a few flaws	https://www.engadget.com/olliolli-world-nintendo-switch-gameplay-143025193.html?src=rss	x OlliOlli World x is a great Switch experience despite a few flawsOlliOlli World the delightfully offbeat skateboarding platformer launched a few weeks ago on basically every gaming console you could ask for It s a clean break for the series taking familiar gameplay but putting it in a totally redesigned world that allows for more exploration competition and tricks You may not recall but the original OlliOlli was released in exclusively for the PS Vita before hitting more platforms over the following years That was my first exposure to the game and I played it non stop whenever I traveled for a few years the Vita was a constant companion on work trips and vacations alike I sunk untold hours into the two OlliOlli games on the Vita mastering almost everything they threw at me I was never able to hack the insane “Rad mode where you had to make every single landing perfectly or else you d slam and have to start the level over So while I was thrilled to try OlliOlli World on the PS I ve also been wondering how it works on the Switch ーwould this be my new on the go gaming addiction or do the compromises of playing on aging hardware degrade the experience After a couple weeks I m happy to say that OlliOlli World looks and plays great on the Switch Still there are a few things you ll want to know as you decide which platform to buy it on Of course the game gives up some visual fidelity on the Switch ーas with all games p when docked to a TV and p on the console s built in display is as good as it gets a far cry from the beautifully detailed K visuals you ll get on the PS or Xbox Series X OlliOlli World on the Switch does target fps similar to other consoles RollNone of these changes are surprising we all know the Switch is less powerful than modern systems But fortunately these changes largely don t make a difference The character models of your skater as well as the many people you meet across the skateboarding haven of Radlandia are indeed less detailed on the Switch What s most important is that the game s gorgeous art style still shines OlliOlli World is one of the most vibrant games I ve ever played and it looks especially vibrant on the OLED Switch s screen While it took me a few minutes to adjust to the lower resolution experience here I mostly didn t think about it once I got down to the game s core skateboarding action The difference in frame rate is more noticeable OlliOlli World is an extremely fast game one that really benefits from running at fps But despite the fact that developer Roll targeted fps for the Switch there were times that I felt like it dipped even below fps Roll did a great job of making the Switch version feel smooth enough that gameplay isn t usually impacted but sometimes the game would drop frames in a crucial moment that led to me unceremoniously slamming after a trick The vast majority of the time things stayed steady enough that it didn t impact my gameplay But there s no doubt that you ll notice dropped frames compared to how the game plays on the PS I also came across frame rate drops in other parts of the game like the animation that happens when your skater kicks off a run or the loading screen transitions that take place when moving from the map into a level These don t affect gameplay but they re hard to ignore and add to the feeling that the Switch struggles a bit to keep up with the action But the fact that the frame rate usually stays solid when you re on a course is far more important Probably the most significant compromise that comes when playing on the Switch are the Joy Con s relatively tiny analog sticks Compared to the spacious sticks on PlayStation and Xbox controllers it s a bit harder to pull off the game s more complex tricks when playing on the Switch Again though it s not a deal breaker I ve thrown down plenty of impressive runs and beat nearly every single challenge the game has thrown at me over the course of dozens of levels That said I m getting far enough into OlliOlli World on the Switch that levels are getting increasingly difficult and I m a little worried about keeping up with the more difficult levels that ll come over the two worlds I have yet to conquer yet I m confident that I ll be able to make it through basically any level the game throws at me But each level has a number of specific challenges you can optionally complete ーto truly master those I might end up docking my Switch to the TV and playing with the Switch Pro Controller which has much better analog sticks than the Joy Con On the other hand the PS Vita analog sticks are even smaller than those on the Switch and I eventually mastered two OlliOlli games on that system There s no doubt that bigger controllers make pulling off the game s tricks more comfortable and probably easier but OlliOlli World is still extremely playable on the Switch To sum it up there are a handful of compromises across graphics and gameplay if you choose to play on the Switch rather than a more powerful console But I don t think that they should stop you from playing the game on Nintendo s handheld It s a great pick up and play game the kind of title you can spend a rewarding minutes with or get lost in for multiple hours The experience is a little more refined on Sony and Microsoft s more powerful consoles but you can t easily take that on the go with you If you don t care about that snap it up on the PS or Xbox Series X S But if you re looking for a game that s at home both on your TV and away from it OlliOlli World on the Switch fits the bill perfectly	2022-02-24 14:30:25
