海外TECH	DEV Community	Showcase Your Open Source Contributions Using Gource.	https://dev.to/wiseai/showcase-your-open-source-contributions-using-gource-53e4	Showcase Your Open Source Contributions Using Gource Open source contributions are a great way to help new community members learn new skills One of the most critical aspects of these contributions is that they are always done in a collaborative effort However extracting insights from raw contributions data can be hard without graphical representations involved The good news is that visualization is a powerful technique for communicating information It can be used in many different ways such as analyzing data making inferences and creating compelling presentations Visualizing data has become more critical in today s world because of the increase in technological advancements Visualizations allow people to see patterns and trends that might have been difficult to notice otherwise Visualizing contributions is not always necessary for all open source projects However it can benefit certain types of projects or specific audiences unfamiliar with the project It is quite important to mention that contributing to open source projects is not just about writing code it also includes bug reports documentation and other contributions In this article we will explore how FFmpeg and Gource in particular can help us visualize the contributions of a given project and understand how it has evolved Psst if you want to follow along with this tutorial consider the following steps assuming you are a Linux user Clone the web py repo and cd into it git clone amp amp cd web py Create a new directory called img download and save my Github avatar inside that directory mkdir img amp amp cd img Table Of Contents TOC What Is Gource Gource InstallationGource UsageWhat Is FFmpeg FFmpeg InstallationFFmpeg UsagePutting It All TogetherWrapping UpReferences What is Gource Go To TOC Gource is a free and open source software visualization tool used to create D animated visualizations of the source code development of a given software The visualization is generated by connecting to a version control repository such as a git repository and using the commit logs or manually generated logs to produce an animated video This means that it is not designed to show off any particular aspect of design or function instead it shows how much work went into creating something and how it evolved Gource was created by Andrew Caudwell It supports Git Bazaar Mercurial and SVN as version control systems Apparently the name Gource was inspired by the word Graph and the term Source according to rumors What makes Gource so popular is the fact that it is featured on Debian and ubuntu manpages Gource can be used for many purposes such as showing the contributions of individual programmers in an open source project or to provide an overview of the different parts of a complex program and how they are connected In the following section we will go over the process of installing Gource on your machine Gource Installation Go To TOC Gource is a cross platform tool which means it is available for Linux Windows Mac Being a humbled Linux user you can install it with apt apt install gourceHowever as stated in the readme file Gource requires OpenGL to run on your machine If you are a Mac user I got you covered But I can t predict what can go wrong for you you can install this tool using homebrew brew install gourceThat s all you need for the installation part Now let s go over some of the common usages of this tool Gource Usage Go To TOC Schematically the Gource command line interface expects the following arguments gource options path options You can run gource H to take a look at the available options path the path of the git directory By default the value for this argument is git Therefore you don t have to explicitly provide it if you are inside a project folder that has a git directory With that noted you can run Gource without any argument like the following gourceGource immediately opens up an animated video window after running the command but it doesn t save it on your machine Notice that it will start streaming from the first commit to the project which is not convenient for large projects To speed things up you can provide additional arguments But before we dive into the details of the available options let s run the following command and observe what is going to happen gource x title web seconds per day auto skip seconds bloom intensity max user speed highlight users highlight dirs hide filenames multi samplingAs you can notice it will generate an animated video at a relatively normal speed Now let s discuss a bit about the options used in the above command x the resolution of the video title web The video s title which will be displayed in the bottom left of the video seconds per day Speed in seconds per day default This argument represents a fraction of time means second per days If you are an active contributor to the project try to increase this value can be considered a modest developer auto skip seconds This parameter tells the program to jump seconds if there is an idle time when there is no commits to jump to the next entry default seconds bloom intensity Adjust the intensity of the bloom default max user speed The velocity at which users can move around default highlight users Highlight all users contributed to the project highlight dirs Highlight the names of all directories hide filenames Don t show filenames multi sampling Enable multi sampling for additional smoothing Gource will take so long to exit for a relatively sizeable open source project because of when the project started and how much work went into it over the years However you can specify a start and stop date to visualize a particular date duration gource x title web seconds per day auto skip seconds bloom intensity max user speed highlight users highlight dirs hide filenames multi sampling start date stop date If you want to understand what is going on in that animation we can refer to the readme file of Gource and I quote The repository is visualized as a tree where the root of the repository is the centre directories are branches and files are leaves Contributors to the source code appear and disappear as they contribute to specific files and directories To highlight a specific user you can provide a highlight user argument and a string representing the username You can also provide an image for a particular user using the user image dir option Directory containing jpg or png images of users e g Full Name png to use as avatars Additionally you can change the highlighter s color using the highlight colour argument by default it is the FFFFFF hex value representing the white color Our command will result in the following gource x title web seconds per day auto skip seconds bloom intensity max user speed highlight dirs hide filenames dirnames multi sampling start date stop date highlight user Mahmoud Harmouch user image dir img highlight colour FFYou can also track movements of a particular user using the follow user and camera mode options gource x title web seconds per day auto skip seconds bloom intensity max user speed highlight dirs hide filenames dirnames multi sampling start date stop date highlight user Mahmoud Harmouch user image dir img highlight colour FF follow user Mahmoud Harmouch camera mode trackNow if we want to write this animated video frame by frame onto your disk using the o gource ppm argument we will end up with a huge file Let s take the following scenario Let s take our Gource command We want to record a video with a resolution of x pixels per frame We need to spend bytes per pixel for color coding Additionally the video runs at frames per second for a total duration of minute resolution pixels frame cost per pixel bytes pixel duration in seconds seconds frame rate frames second storage required duration in seconds frame rate resolution cost per pixel bytes If you do the math this video will require approximately GB of storage for just one minute of the recording That s why you have to use some sort of compression with the help of the FFmpeg command FFmpeg uses a codec to compress the video stream generated by Gource It converts raw digital video to a compressed format That s all you need to know about Gource You can refer to the Readme file if you are looking for additional options or looking them up within your terminal using the gource H command Now let s move on to the FFmpeg section in order to learn how we can store that recording locally on a drive What is FFmpeg Go To TOC The transcoding process in ffmpeg for each output FFmpeg is an open source project for manipulating converting and streaming video and audio data It is most often used to convert video from one format to another but it can also be used for live streaming and recording It is the best known of several such projects The project was started in by Fabrice Bellard in response to a need for a tool to convert video from one format to another with particular attention to the then new MPEG standard The name FFmpeg was originally an acronym for Fast Forward MPEG Player The project has since expanded its scope to include encoding transcoding streaming recording playback conversion and multimedia content manipulation For complete and detailed information on how this tool works you can refer to the documentation which does a great job in terms of explaining things FFmpeg Installation Go To TOC To install FFmpeg on a Linux machine open your favorite terminal and type the following command apt install ffmpegor if you are using a Mac OS you can use homebrew to install it on your machine brew install ffmpegHaving FFmpeg installed on your machine let s take a look at some useful commands that can be helpful in your daily work with multimedia content FFmpeg Usage Go To TOC Schematically the FFmpeg command line program expects the following number of arguments to accomplish its job ffmpeg options infile options i infile outfile options outfile The primary usage of this command is the following ffmpeg i input mp r output gifIt will convert an mp video file into a gif with a frame rate equal to However for the purpose of this article we need to read a stream of data from gource and save it on a local drive To do so we need to change the input filename to to read from STDIN Recall from the above Gource Usage section we need to compress the data generated by Gource In the next section we are going to put things together to generate a nicely compressed video file Putting It All Together Go To TOC To use FFmpeg along with Gource I found a handy tutorial on the wiki page of the Gource repo With that noted our final command will result in the following gource x title web seconds per day auto skip seconds bloom intensity max user speed highlight dirs hide filenames dirnames multi sampling start date stop date highlight user Mahmoud Harmouch user image dir img highlight colour FF follow user Mahmoud Harmouch camera mode track o ffmpeg y r f imagepipe vcodec ppm i vcodec libx preset ultrafast pix fmt yuvp crf threads bf gource mpThis command will generate the following recording The FFmpeg command will convert the ppm file generated by Gource to a regular mp format This is done using Gource o abbreviation for output ppm stream and converting this stream of images into the mp format using the FFmpeg utility Wrapping up Go To TOC I will conclude by stating that open source visualization tools are potent and flexible enough to create complex visualizations helpful in extracting meaningful insights from contributions data This constitutes our guide for today on using Gource to visualize the development of your project beautifully Using this tool you can quite impress your colleagues or coworkers with some cool visualizations to show off your contributions Not a popular argument but some may argue that using this type of tool can harm your privacy to some extent by tracking your contributions to a given project Some people don t like this idea so they keep their contributions private For others it is some sort of cringe to show off your work and I can t agree more Just stay calm keep coding and deliver something useful for the whole damn world But it can motivate you by creating a feedback loop that is essential to your professional development and maintain your happiness in the long run As always this article is a gift to you and you can share it with whomever you like or use it in any way that would be beneficial to your personal and professional development By supporting this blog you keep me motivated to publish high quality content Thank you in advance for your ultimate support I am looking forward to your comments about using this tool in the comments section below And I hope you enjoyed reading this article and learned something valuable from it That s all for today s article Thank you for reading Stay hydrated folks see you in the next one References Go To TOC Andrew Caudwell Software version

海外TECH	DEV Community	Add a smart 'back to top' button to your blog 👓🔝	https://dev.to/robole/add-a-smart-back-to-top-button-to-your-blog-ci7	Add a smart x back to top x button to your blog A back to top button helps users navigate to the top of long pages It is a common UI pattern You have probably seen it implemented as a floating button with an up arrow positioned in the bottom right of the page I want to do a smart version By this I mean the button is hidden until a user has scrolled down a page AND then scrolls up I have seen different implementations with some good things and not so good things so I would like to address these with regard to usability and accessibility Not totally sure what it is exactly still You can see one on CSS Tricks as per screenshot below just scroll down a bit and it will appear Things to consider before adding it to your blogBefore you implement one on your site you should take a moment to evaluate if you need this based on the design and content of your website The Nielsen Norman Group has some useful User Experience UX guidelines on this Why use it When users get further into a really long page they often will need to get back to the top to See the navigation menu and choose where they want to go next Access sorting and filtering features Make a query in the search box If you have navigation at the bottom of the page or you have sticky navigation menus then you may not need this button If don t have these features in your layout and you have long content longer than screens in length then you can consider adding the button How do we want it to look and behave For the appearance we want the following Place it in the bottom right corner of the page Make it big enough to click but small enough so that it does not block a lot of content Make it stand out visually by making it a floating button via shadows For the behavior we will Delay the appearance until the users scroll down a page AND indicates that they want to up by scrolling up We want the scrolling to the top of the page to be smooth not an instant jump There are variations on this of course I have included some alternative examples in the Alternative implementations section if you would like to do it differently Should I use a link or button A good rule of thumb is to use a link for navigation and a button for actions Since we are navigating to the top of the page a link is a better fit Is there a CSS only solution Not for my exact requirements Termani Afif offers a CSS only solution in this article discussed further in Alternative implementations section The button appears after the user scrolls down a fixed amount one screen plus an offset The difference with my solution is that the button remains visible beyond that point If you don t care about hiding the button based on scrolling then Termani s solution is a better option My solutionIn the simplest form we just need to create a bookmark link That is where the href contains a hash We will use an icon to keep the size of the button small You can use text instead if you prefer And then we need to write a bit of JavaScript to show the button Here is the finished article Now let s go through the code HTMLI think it is a good idea to place the link at the start of your main content rather than at the very bottom of the body This gives keyboard users the opportunity to tab to it first If they need to tab all the way to the last thing in your main content it kind of defeats the purpose of it I use an empty bookmark reference just a hash in the href of the link that will take us to the root top of the document I use an icon rather than text inside the link to keep the size small I choose the chevron up icon with the solid fill from hero icons I copied the SVG and pasted inside the a element We will set the size of the icon in CSS later lt html gt lt body gt lt main navigation gt lt a href class top link aria label Go to top aria hidden true gt lt svg xmlns viewBox fill currentColor role presentation gt lt path fill rule evenodd d M a L l a l a l a z clip rule evenodd gt lt svg gt lt a gt lt lot more stuff here gt lt body gt lt html gt We should consider accessibility further Since the link is hidden by default we will add aria hidden true so that it is hidden from assistive technologies also Since the link has no text it will be confusing to screen readers and assistive technologies when the link is shown You could leave it always hidden with aria hidden true if you think that this is something that is not required by assistive technologies Screen reader users have the ability to jump to major page sections so they probably do not need it but I am not sure about others I think it is good to give everyone the option to use it So I will make it fully accessible by adding alternative text to the link through the aria label attribute I add role presentation to the SVG icon to remove it from the accessibility tree Our JavaScript code will change the value of aria hidden to true to show the link CSSWe want the link to be fixed in the bottom right corner as this is where people expect to see it We use position fixed to fix the position along with the bottom and right properties to place it into the bottom right I position a small distance from the corner to stand out well To factor in the sizing of our link we can consult the Web Content Accessibility Guidelines WCAG which is a standard for making web content more accessible to people with disabilities The guideline for target size says that our link anchor link in their words does not need to meet the requirement of being by CSS pixels because a user can scroll However I think getting close to that size is a good idea We fufill this by setting the height and width of the SVG To create a floating effect we add a subtle offset shadow below the element with box shadow The values I use below for box shadow is the same as what Material Design uses for its floating action buttons top link position fixed right px bottom px background color rgb padding margin border radius box shadow px px px px rgba px px px px rgba px px px px rgba transition transform s ease in out top link svg height rem width auto a aria hidden true transform scale html scroll behavior smooth To support accessibility as best as we can we will use the aria hidden attribute for style the hiding of our link This way wont forget to add it to the HTML and JS We use a scale transformation transform scale to hide the link This shrinks the size of the link to zero We do this so we can animate it when it is shown and hidden We add transition transform s ease in out to the top link class to achieve this Finally we use scroll behavior smooth to ensure when you click the link it scrolls to the top in a smooth fashion This is applied to the html element so this will be the behaviour for your entire site JavaScriptWithout adding any JavaScript Our link does the job and looks good However the link is there all the time and we do not want that The sole mission of this JavaScript code is to control when the link will be visible We only want the link to appear after the user has scrolled down at least screens and begins to scroll up In a previous post How to detect scroll direction in vanilla JavaScript to make a goofy logo animation I describe how to determine if a user is scrolling up or down I use a scroll event listener to react to the user s scroll activity I also discuss how a throttle function can improve the performance of the scroll event handling I will use the throttle function from the lodash library in this example If you are not familiar with throttling give the post a read to understand it fully The quick takeaway is that we have a isScrollingDown function that determines if a user is scrolling up or down We use this function as a condition in our scroll event handler to determine if we should hide or show the link Our second condition is to only show the link when we have scrolled down at least a single screen by screen we mean the viewport height The window innerHeight property is the height of the viewport let backToTopLink document querySelector top link let previousScrollPosition const isScrollingDown gt let goingDown false let scrollPosition window pageYOffset if scrollPosition gt previousScrollPosition goingDown true previousScrollPosition scrollPosition return goingDown const handleScroll gt let viewportHeight window innerHeight let scrollPosition window pageYOffset if isScrollingDown backToTopLink setAttribute aria hidden true else if isScrollingDown false amp amp scrollPosition gt viewportHeight backToTopLink setAttribute aria hidden false the throttle is provided by the lodash libraryconst scrollThrottle throttle handleScroll window addEventListener scroll scrollThrottle And that s it Hopefully the code is clear enough that you can understand it all Alternative implementationsThere are variations on this functionality I wanted to do it a different way that s why I wrote my own version You may like to do it a bit different to me so I included some alternative examples I added some comments to discuss some pros and cons of these implementations and I highlight some issues I found when I went through them How to Make an Animated Back to Top Button Using Only CSS by Temani Afif FreeCode Camp The author is looking to create a back to top button using only CSS It is a nice solution The button appears after the user scrolls down a fixed amount one screen plus an offset The difference with my solution is that the button remains visible beyond that point The animation effects discussed did not work for me in Firefox Linux but did in Chrome Linux This is because the mask property is used in both effects The mask property is not a well implemented CSS feature the browser support is odd unfortunately So you should be cautious in using the animations In the examples where only an icon is used accessibility is not considered How to Make an Unobtrusive Scroll to Top Button by Marcel Rojas CSS Tricks The author is looking to make a button that is non obtrusive while still being a large enough target to tap or click The author places the go to top button in the footer of the website and uses a button with the emoji as the text content The button has no aria label which is not good for accessibility Two different implementation are demonstrated A scroll event listener is used to show the button when the user scrolls down of the page height This code is not optimized and the author suggests using the second method instead To optimize the code you would need to consider throttling the number of scroll events It uses the Intersection Observer API to show the button when the footer comes into view This seems kind of pointless to me Why even use JavaScript just put the link in the footer and call it a day I guess it is just to demo the code for using Intersection Observer but it is not a very practical example in my opinion	2022-04-27 13:19:23
海外TECH	DEV Community	LINUX Questions!!!	https://dev.to/halilkaran/linux-interview-questions-4i53	LINUX Questions What is Linux Linux is an operating system based on UNIX and was first introduced by Linus Torvalds It is based on the Linux Kernel and can run on different hardware platforms manufactured by Intel MIPS HP IBM SPARC and Motorola Another popular element in Linux is its mascot a penguin figure named Tux What is the difference between UNIX and LINUX Unix originally began as a propriety operating system from Bell Laboratories which later on spawned into different commercial versions On the other hand Linux is free open source and intended as a non propriety operating system for the masses What is BASH BASH is short for Bourne Again SHell It was written by Steve Bourne as a replacement to the original Bourne Shell represented by bin sh It combines all the features from the original version of Bourne Shell plus additional functions to make it easier and more convenient to use It has since been adapted as the default shell for most systems running Linux What is Linux Kernel The Linux Kernel is a low level systems software whose main role is to manage hardware resources for the user It is also used to provide an interface for user level interaction What is the advantage of open source Open source allows you to distribute your software including source codes freely to anyone who is interested People would then be able to add features and even debug and correct errors that are in the source code They can even make it run better and then redistribute these enhanced source code freely again This eventually benefits everyone in the community What are the basic components of Linux Just like any other typical operating system Linux has all of these components kernel shells and GUIs system utilities and an application program What makes Linux advantageous over other operating system is that every aspect comes with additional features and all codes for these are downloadable for free Describe the root account The root account is like a systems administrator account and allows you full control of the system Here you can create and maintain user accounts assigning different permissions for each account It is the default account every time you install Linux What is CLI CLI is short for Command Line Interface This interface allows the user to type declarative commands to instruct the computer to perform operations CLI offers greater flexibility However other users who are already accustomed to using GUI find it difficult to remember commands including attributes that come with it What is GUI GUI or Graphical User Interface make use of images and icons that users click and manipulate as a way of communicating with the computer Instead of having to remember and type commands the use of graphical elements makes it easier to interact with the system as well as adding more attraction through images icons and colors How do you change permissions under Linux Assuming you are the system administrator or the owner of a file or directory you can grant permission using the chmod command Use symbol to add permission or symbol to deny permission along with any of the following letters u user g group o others a all r read w write and x execute For example the command chmod go rw FILE TXT grants read and write access to the file FILE TXT which is assigned to groups and others What are filenames that are preceded by a dot In general filenames that are preceded by a dot are hidden files These files can be configuration files that hold important data or setup info Setting these files as hidden makes it less likely to be accidentally deleted What is the pwd command The pwd command is short for print working directory command What are the kinds of permissions under Linux There are kinds of permissions under Linux Read users may read the files or list the directory Write users may write to the file of new files to the directory Execute users may run the file or lookup a specific file within a directoryWhat are the different modes when using vi editor There are modes under vi Command mode this is the mode where you start in Edit mode this is the mode that allows you to do text editing Ex mode this is the mode wherein you interact with vi with instructions to process a fileWhy we use LINUX LINUX is used widely because it is completely different from other operating systems where every aspect comes with something extra i e some additional features Some of the major reasons to use LINUX are listed belowIt is an open source operating system where programmers get the advantage of designing their own custom OSSoftware and the server licensing required to install Linux is completely free and can be installed on many computers as requiredIt has low or minimum but controllable issues with viruses malware etcIt is highly secured and supports multiple file systemsEnlist some Linux distributors Distros along with its usage Different parts of LINUX say kernel system environment graphical programs etc are developed by different organizations LINUX Distributions Distros assemble all these different parts of Linux and give us a compiled operating system to be installed and used There are around six hundred Linux distributors Let us see some of the important onesUBuntu It is a well known Linux Distribution with a lot of pre installed apps and easy to use repositories libraries It is very easy to use and works like a MAC operating system Linux Mint It uses cinnamon and mates desktop It works on Windows and should be used by newcomers Debian It is the most stable quicker and user friendly Linux Distributors Fedora It is less stable but provides the latest version of the software It has a GNOME desktop environment by default Red Hat Enterprise It is to be used commercially and to be well tested before release It usually provides a stable platform for a long time Arch Linux Every package is to be installed by you and is not suitable for beginners Explain Linux Shell For executing any commands user uses a program known as the shell Linux shell is basically a user interface used for executing the commands and communicating with Linux operating system Shell does not use the kernel to execute certain programs create files etc There are several shells available with Linux which includes the followingBASH Bourne Again SHell CSH C Shell KSH Korn Shell TCSHWhat is the maximum length for a filename in Linux characters How to delete information from a file in vi The following commands are used to delete information from vi editors x deletes a current character dd deletes the current line	2022-04-27 13:18:31

headphones I raised my hand In addition to fit and battery life I considered factors such as style ease of use the charging case the strength of the Bluetooth connection support for assistants such as Siri and Alexa water resistance ratings and audio features such as noise cancelation and ambient sound modes You ll notice I don t have much if anything to say about audio quality Engadget s resident expert Billy Steele has written about this plenty in his standalone reviews which I ve linked throughout but for my purposes the differences were too subtle to make or break a purchasing decision In the end I never quite mastered some of the over complicated controls but at no point did an earbud fall out while I was exercising I also never came close to running out of juice So participation trophies for everyone Ha The companies wish I do indeed have some favorites while some fell short in key areas How we testedWater resistanceEven if earbuds aren t marketed specifically as workout headphones a durable water resistant design will by default make them suitable for exercise To avoid repeating myself throughout this guide I ll drop a quick primer here on durability or ingression protection IP ratings The first digit you ll see after the “IP refers to protection from dust and other potential intrusions That spec is measured on a scale of to The second refers to water resistance or even waterproofing in the best cases Higher numbers mean more protection while the letter “X means the device is not rated for protection in that regard The ratings for water resistance are ranked on a scale of to All but one of the models we tested for this guide is rated IPX That means there s no dust protection and the buds can withstand splashes from any direction but probably shouldn t be submerged The most durable set of earbuds we tested Jabra s Elite Active is rated IP which means a high level of both dust and water protection Whereas the IPX models can handle splashes the Elite Active can be immersed for up to minutes in up to a meter or about feet of water For a detailed breakdown of all the possible permutations I recommend checking out this guide published by a supplier called The Enclosure Company Earbuds we testedDurability ratingBeats Powerbeats ProIPXBeats Fit ProIPXJabra Elite Active IPSony WF CIPXAnker Soundcore Liberty ProIPXActive noise cancelationFor the update to this guide I decided to add a note up top about active noise cancelation ANC simply because most of the available models now offer it And since the user experience is actually pretty similar across different brands I thought it would be easier to share what they have in common rather than repeat myself First of all no noise cancellation is perfect If you re looking for earbuds that you can continue wearing even after you re done working out you might still hear some background noise whether it be your robot vacuum or cars honking The difference in quality with ANC enabled is undeniable just don t take these companies marketing claims too literally Besides I don t recommend active noise cancellation while exercising outdoors it s not safe And even if you are working out indoors I still think a noise cancellation horse race is probably beside the point for the purpose of this guide The best all purpose option Jabra Elite ActiveBilly Steele EngadgetWhat you get A stylish compact pair of wireless earbuds with a lightweight charging case to match Pros Reasonably priced for the feature set sleek compact design one of the lightest charging cases we tested and some of the longest battery life more durable than most active noise cancelation a transparency mode and customizable equalizer works with Spotify Tap on Android Cons Onboard controls aren t intuitive but Jabra offers helpful instructions in its app less comfortable after prolonged use than other brands Buy Elite Active at Amazon Much like the Elite Active t we tested in the newer Elite Active earbuds make a strong first impression with a compact stylish design and a lightweight charging case to match Available in three colors the earbuds aren t just small and light but they look especially sleek given that they don t have any wingtips Though they felt comfortable when I first put them in my ears did feel a little sore by the end of a run Meanwhile the gram case is also among the lightest we tested but still offers some of the longest battery life promising a total of hours Each individual earbud on its own is rated for seven hours Jabra says you can return to an hour s worth of juice after a minute charge In my testing the earbuds were easy to insert and pair Less easy is learning how to use the things As you might expect you press the right earbud once to stop and resume playback You can also double press the right bud to skip a track and triple press it to play it again But some of the other onboard controls are less obvious To increase the volume hold down the right earbud for a second to lower it long press the left earbud Meanwhile single pressing the left earbud allows you to toggle between active noise cancelation HearThrough mode or neither Lastly double press the left bud to use a voice assistant The good news is you don t have to commit all those finger gestures to memory Jabra s Sound App for iOS and Android contains a helpful illustrated tutorial which I recommend keeping open on your phone as you get settled in with your new earbuds I mastered the controls quickly enough but the physical buttons on the earbuds require a little more pressure and coordination to get an accurate press in I found myself waiting until I had slowed to a walk before I started fiddling with the tracks Even then I needed to be very deliberate to make sure I got it right And usually I did That said given there s no physical volume rocker I did wish there were an aural cue confirming I had moved the volume up or down a notch the progression from louder to softer or vice versa is very subtle After a roughly minute run the battery was still at percent a similar showing to what I saw on the Beats Fit Pro also featured in this guide Like the Elite Active t I tested previously the Elite Active uses Jabra s HearThrough technology With that enabled I could hear cars along my running route though on an especially windy day the gusts drowned out softer noises like footsteps behind me That s despite the earbuds having four built in mics with what Jabra calls a “mesh covering for added wind noise reduction Although I tested the Elite Active on an iPhone the earbuds have some additional features on Android including support for Spotify Tap which resumes where you last left off listening to your Spotify account on any device Android users also get support for Alexa and Google s Fast Pair tech While I recommend the Elite Active for most people it s also worth quickly mentioning the Elite Active which adds Jabra s ShakeGrip technology for what the company claims is a more secure fit You also get slightly better battery life eight hours per bud or hours with the case and even faster charging an hour of playback after a five minute charge Lastly choosing the Elite Active over the Elite Active gives you the option of either Google Assistant or Alexa as well as voice guidance However you d be giving up call controls which you do get on the Elite Active The most comfortable option Beats Powerbeats ProWhat you get A comfortable behind the ear hook design that s easy to use and is deeply integrated with iOS Pros Comfortable stable fit pairs seamlessly with iOS devices intuitive controls with mirrored access on the left and right sides tied with Sony for the longest earbud battery life Cons Ear hook design isn t the most discreet and doesn t fit so well with sunglasses relatively heavy charging case no active noise cancelation transparency mode or customizable EQ speaking to an assistant is slightly less convenient if it s not Siri Buy Powerbeats Pro at Amazon For the purposes of this guide I tested two pairs of Beats headphones the Beats Fit Pro earbuds and the Powerbeats Pro earbuds with an over the ear hook design I ll start with the Powerbeats Pro which I like better for exercising Other than being slightly conspicuous the Powerbeats Pro comes in four colors and fits comfortably though it doesn t play as nicely with glasses and face masks as more compact in ear designs Compared to the other earbuds I tested though I felt especially confident the Powerbeats Pro would stay put during workouts Like Apple s newest AirPods the Powerbeats Pro use Apple s H chip which allows for particularly deep integration when you pair the earbuds with an Apple made device In addition to a fast seamless pairing process you can activate Siri by saying “Hey Siri without having to press a button You can also share audio with other AirPods or Beats headphones and can enjoy automatic switching between Apple devices For better and worse the integration is so complete in fact that there s no companion app instead you check the earbuds and cases battery via other methods such as a homescreen widget or by asking Siri The earbuds themselves are rated for nine hours of use which is among the highest we ve seen The case is rated for a total of hours of use which isn t bad but given that it s not best in class you have to wonder why the case is as heavy as it is Heavy enough that my purse feels a little lighter without it iOS users won t mind that the case charges via a Lightning cable and not USB C but others might be slightly put out If you ve ever used AirPods or Apple s old school wired headphones these should be pretty easy to master Double press the physical button on the earbud to skip tracks and triple press it to go backward I quickly came to love the physical key it s less finicky than a touch surface I was also grateful for the mirroring of controls between the left and right earbuds ーboth left and right handed people should be happy Having tested other wireless earbuds that either lack onboard volume controls or make it tedious I have come to particularly appreciate the Powerbeats Pro s onboard volume rockers one for each earbud I don t know of any other workout earbuds that make it easier to adjust the volume not even the Beats Fit Pro While it s nice to have easier volume access the audio experience is otherwise basic There is no active noise cancellation or transparency mode Not a dealbreaker for workouts but something to consider if your goal is to get one pair of earbuds you can wear for everything Other features include support for voice assistants yes Google and Amazon too but only Siri can be summoned by a voice command You can also wear just one bud if you like the right one if all you need to do is talk on the phone or if you want to keep an ear open to what s going on around you nbsp Honorable mention Beats Fit ProBilly Steele EngadgetWhat you get Many of the benefits of the Powerbeats Pro with a more discreet design a lighter charging case and the addition of ANC Pros Comfortable stable fit pairs easily with iOS devices compact lightweight charging case adds ANC and transparency modes which the Powerbeats Pro lacks Cons A smaller design than the Powerbeats Pro means shorter battery life and the loss of a physical volume rocker no customizable EQ Buy Beats Fit Pro at Amazon One of my main complaints about the Powerbeats Pro is that they don t fit as well if you re wearing sunglasses or in pandemic times a mask This is where the Beats Fit Pro have the advantage Their discreet design that promises to stay out of the way and safe even during sweaty workouts Available in four colors the buds are easy to insert and comfortable to wear just twist the bud to fold the wingtip into your upper ear And because the earbuds are smaller than the Powerbeats Pro the case is markedly lighter and more compact g versus g on the Pro Between the lightweight case and the less dorky design the Beats Fit Pro make a strong case for themselves as earbuds you can wear not just during workouts but everywhere Because the Beats Fit Pro were released more recently than the Powerbeats Pro they have active noise cancellation a feature older Powerbeats and AirPods products are lacking At the same time Apple built in a transparency mode ideal for runners like me who would feel safer if they could still hear ambient cues like footsteps and car horns Lastly it supports Apple s Spatial Audio format for a more immersive sound and will automatically kick in if you re playing a compatible track For working out the audio is fine But if you can only afford one pair of earbuds my colleague Billy Steele indicated in his review that the sound quality is mediocre He found calls could be patchy and as he notes Beats is one of the few brands that doesn t offer users a customizable EQ Out of the box the earbuds are set to active noise cancellation There are two ways to adjust this You can hold down the physical button on either earbud to cycle through audio profiles Or you can find the earbuds in your Bluetooth settings menu and click further to see a more detailed menu of options Not only can you adjust the mode there but you can also change what those physical buttons do By default they re for toggling audio profiles but you can also set them up so that one earbud controls volume up and the other volume down Personally I preferred having the option of adjusting the volume from my earbuds mid workout it s easy to just pick an audio mode before your run and stick with it Other than the slightly limited volume controls the Beats Fit Pro works much like other Beats and Apple branded headphones Press the physical button once to play or pause tracks double press to skip forward and triple press to replay a track For anyone upgrading from an older pair of Beats or Apple earbuds the transition should be easy My only word of caution is that I found the physical button on the Beats Fit Pro harder to find by feel as it s smaller and less indented than the button on the Powerbeats Pro Apple rates the Beats Fit Pro for six hours of listening time per earbud plus an additional hours from the USB C charging case You can also wear just one bud if you like to squeeze out even more runtime In my testing the battery on the buds dropped down to percent after a minute run Extrapolate that and the math comes close to Apple s six hours per bud claim If you ve managed to completely exhaust both the earbud and case Apple says its “Fast Fuel feature will get you back to one hour of use after five minutes of charging the same claim Jabra makes for the comparably priced Elite Active Note Apple s one hour estimate assumes you won t be using ANC Under the hood the earbuds have the same Apple made H chip as the Powerbeats Pro and Apple s newer AirPods allowing for hands free “Hey Siri audio sharing with other AirPods or Beats headphones and automatic switching between devices The headphones also work with the Find My app even on Android The best budget workout earbuds Sony WF CEngadgetWhat you get Reasonably priced earbuds that prioritize a light design and good audio quality Pros Lightweight reasonably priced support for Sony s Reality Audio format the earbuds themselves claim relatively long battery life customizable EQ supports Google Fast Pair Cons No ANC or transparency mode slightly trickier to pair on iOS than other earbuds we tested the charging case has lower capacity than competing models they have a larger more bulbous design than others we tested but are no less comfortable Buy WF C at Amazon With the WF C earbuds Sony is really emphasizing the small design The earbuds themselves weigh grams while the charging case is g That would be the lightest case we tested and nearly the lightest pair of earbuds barring the much pricier Elite Active It s worth noting that a lighter charging case means shorter case battery life a relatively low hours Even then the earbuds themselves offer some of the longest battery life of the bunch hours per bud If you do run low on charge you can get back up to an hour s worth of capacity in minutes Sony says The earbuds available in four colors were larger than I was expecting given their light weight but they re easy to insert and fit comfortably They are slightly trickier to pair on iOS than other buds I tested for this guide though Android users will benefit from support for Google Fast Pair By default a robotic voice will tell you the earbuds battery charge as you re putting them in I found this useful though it meant that there was a delay in getting to hear whatever I had been listening to You can always disable voice guidance in Sony s Headphones app if that bothers you The truth is I rarely had range anxiety with these headphones anyway Unlike other earbuds which took a roughly percent hit after my usual minute run these were still at percent It s unlikely I ll ever wear out both the buds and charging case before getting to a wall charger The controls were also easy to master without having to consult Sony s companion app On the right earbud press once to play or pause audio playback or to answer or end a call Double press to skip tracks and triple press to go to the previous song Long pressing the right earbud launches or cancels a voice assistant You can also long press to decline a call On the left earbud some of the controls are mirrored you can press once to receive end a call and long press to reject it The left bud is also where the volume controls live press once to raise it and hold the button down to lower it As one of the cheaper options in this guide the WF C are the only ones without active noise cancellation Which to me isn t a dealbreaker The eartips already do a good enough job passively blocking noise to the point where I was startled when a group of runners ran up from behind in the park and passed me If anything I wished the earbuds had a transparency mode that would allow more ambient noise through Fortunately I could still hear louder noises like nearby traffic The lack of ANC aside the audio quality is quite good which makes sense given Sony s heritage in audio and home theater gear Like other models listed here barring Beats anyway you can adjust the EQ in the companion app And as you might expect the earbuds support Sony s Reality Audio format which is similar to Apple s spatial tech which in turn is built on the Dolby Atmos format The most customizable Anker Soundcore Liberty ProEngadgetWhat you get Comfortable ANC earbuds with long battery life and customizable controls Pros The only buds we tested with wireless charging long battery life especially on the charging case active noise cancelation a transparency mode and customizable equalizer lots of options for setting up the controls to your liking Cons Larger and a little harder to insert than competing models touch sensitive controls can be finicky worse sound quality than the competition in app battery indicator doesn t give you a percentage Buy Soundcore Liberty Pro at Amazon The Soundcore Liberty Pro earbuds are available in four colors and carry a big emphasis on ergonomic fit That includes air filled wings silicone ear tips similar to other brands and a promise of air pressure relief per Anker The earbuds don t come with the eartips or wingtips attached which adds some friction to the setup process but on the plus side you get a choice of four ear tip sizes compared with three from most other headphone makers Inside the Soundcore app you ll find a fit test but I actually ended up with a more comfortable fit by just following my gut But it s certainly worth playing around with The Liberty Pro is right up there with the Sony CF in terms of being some of the larger earbuds I tested for this guide That said they fit comfortably and stay put I will say however that these were consistently harder to insert than some other brands I tested even after I d had a bit of practice When I originally published this guide in September I ruled out Anker s Soundcore Spirit Dot earbuds on account of their fussy touch controls and the fact that you couldn t adjust the volume from the buds themselves I m happy to report that the situation has improved mostly First the bad news The controls are still finicky and especially difficult to get right while moving But they do offer volume control Thank goodness The controls are also programmable inside the Soundcore app So you can at least customize the long press and single double and triple taps in a way that feels intuitive In addition to music and volume playback you can also use the controls to toggle audio modes or to activate a voice assistant Google or Alexa Just as you can modify the earbud controls you have options as far as sound quality too There are ANC and transparency modes along with a “normal setting in between Also like Sony and Jabra Anker allows you to customize the EQ from within the app Interestingly wind reduction is a feature you have to actively opt into Anker says this is because the wind reducing mode dings ANC performance and since it s unlikely people will often find themselves in strong winds it may as well not be turned on by default Later this year Anker will push out a software update that will add “enhanced vocal mode which promises to increase vocal pickup in the area around you according to an Anker spokesperson Additionally Anker touts three mics per earbud along with AI noise reduction I can t prove that there s a connection here but I did notice they sounded a little tinnier compared with other headphones Sometimes some random buzz even crept in It s hard to know if that slight distortion is a result of the AI doing its work but I wonder As for battery life the Soundcore Liberty Pro has the distinction of being the only earbuds we tested for this guide with a case that can charge wirelessly The buds themselves are rated for eight hours apiece or hours with the case making this the longest lasting charging case we tested for this story Anker also says that you can return to three hours of capacity after minutes of charging After a minute run the battery indicator in the app showed a mostly full charge though unfortunately Anker doesn t give you a percentage	2022-04-27 13:30:09
