Localization Use Cases
_ = navigator.mozl10n.get; element.textcontent = _(l10nid, { size: sizeinfo.size, unit: _('byteunit-' + sizeinfo.unit) }); } the function is used like so: // application storage updateappfreespace: function storage_updateappfreespace() { var self = this; this.getfreespace(this.appstorage, function(freespace) { devicestoragehelper.showformatedsize(self.appstoragedesc, 'availablesize', freespace); }); }, problem definition for all values of freespace, the following string is enough to construct a grammatically-correct sentence in english: availablesize = {{$size}} {{$unit}} available however, other languages might need to pluralize this string with different forms of the available adjective.
... consequently, using the existing localization frameworks, the developer needs to predict which strings might need pluralization in other languages, and pluralize them even in english: availablesize = {[ plural(size) ]} availablesize[other] = {{$size}} {{$unit}} available an italian translation might look like this: availablesize = {[ plural(size) ]} availablesize[one] = {{$size}} {{$unit}} disponibile availablesize[other] = {{$size}} {{$unit}} disponibili it's easy to imagine how developers might forget to pluralize some strings that in other languages might require pluralization (or other grammatical features that the framework supports).
... in l20n, the english string could be as simple as: <availablesize "{{ $size }} {{ $unit }} available"> on the other hand, the italian translation would make use of proper pluralization rules: <plural($n) { $n == 1 ?

Introduction to SSL - Archive of obsolete content
the details of the protocol are available in request for comments (rfc): 2246,the tls protocol version 1.0.
...government restrictions on products that support anything stronger than 40-bit encryption, disabling support for all 40-bit ciphers effectively restricts access to network browsers that are available only in the united states (unless the server involved has a special global server id that permits the international client to "step up" to stronger encryption).
...that way, when a domestic client or server is dealing with another domestic server or client, respectively, it will negotiate the use of the strongest ciphers available.
...they provide the strongest encryption available for exportable products.1 rc4 with 40-bit encryption and md5 message authentication rc4 40-bit encryption permits approximately 1.1 * 1012 (a trillion) possible keys.

Scaling - Game development
the phaser scale object there's a special scale object available in phaser with a few handy methods and properties available.
... update your existing preload() function as follows: function preload() { game.scale.scalemode = phaser.scalemanager.show_all; game.scale.pagealignhorizontally = true; game.scale.pagealignvertically = true; } scalemode has a few different options available for how the canvas can be scaled: no_scale — nothing is scaled.
... exact_fit — scale the canvas to fill all the available space both vertically and horizontally, without preserving the aspect ratio.
... resize — creates the canvas with the same size as the available width and height, so you have to place the objects inside your game dynamically; this is more of an advanced mode.

WAI-ARIA basics - Learn web development
for example, html5 introduced a number of semantic elements to define common page features (<nav>, <footer>, etc.) before these were available, developers would simply use <div>s with ids or classes, e.g.
... the improved semantics of the search form have shown what is made possible when aria goes beyond the semantics available in html5.
... guiding users through complex widgets there are a whole host of other roles that can identify non-semantic element structures as common ui features that go beyond what's available in standard html, for example combobox, slider, tabpanel, tree.
... summary this article has by no means covered all that's available in wai-aria, but it should have given you enough information to understand how to use it, and know some of the most common patterns you will encounter that require it.

What is accessibility? - Learn web development
you should look at your project budget and think about what solutions you have available to make such content accessible.
... accessibility guidelines and the law there are numerous checklists and sets of guidelines available for basing accessibility tests on, which might seem overwhelming at first glance.
... so while the wcag is a set of guidelines, your country will probably have laws governing web accessibility, or at least the accessibility of services available to the public (which could include websites, television, physical spaces, etc.) it is a good idea to find out what your laws are.
... different operating systems have different accessibility apis available : windows: msaa/iaccessible, uiaexpress, iaccessible2 mac os x: nsaccessibility linux: at-spi android: accessibility framework ios: uiaccessibility where the native semantic information provided by the html elements in your web apps falls down, you can supplement it with features from the wai-aria specification, which add semantic information to the accessibility tree to improve accessib...

Beginner's guide to media queries - Learn web development
for users who can hover, we might choose to make them available when a link is hovered over.
...that's the point at which you want to use a media query to change the design to a better one for the space you have available.
... if you look at the final example at different widths you can see how the design responds and works as a single column, two columns, or three columns, depending on the available width.
...the nice thing about this method is that grid is not looking at the viewport width, but the width it has available for this component.

Supporting older browsers - Learn web development
this is straightforward if you have an existing website which you are adding to or replacing, as you probably have analytics available which can tell you the technology people are using.
... once you know the browsers that come to your site, you can assess any technology that you want to use against how well it is supported and how easily you can provide an alternative for visitors who do not have that technology available.
...having access to older versions of internet explorer is particularly useful, and for that purpose, microsoft has made a range of virtual machines available for free download.
... these are available for mac, windows and linux operating systems and so are a great way to test in old and modern windows browsers even if you are not using a windows computer.

What is a Domain Name? - Learn web development
they provide a human-readable address for any web server available on the internet.
...this is so that unused domain names eventually become available to use again by someone else.
... finding an available domain name to find out whether a given domain name is available, go to a domain name registrar's website.
... most of them provide a “whois” service that tells you whether a domain name is available.

UI pseudo-classes - Learn web development
in this article, we will explore in detail the different ui pseudo-classes available to us in modern browsers for styling forms in different states.
... what pseudo-classes do we have available?
... the original pseudo-classes available to us (as of css 2.1) that are relevant to forms are: :hover: selects an element only when it is being hovered over by a mouse pointer.
... <input>, <select>, and <textarea> elements have a required attribute available which, when set, means that you have to fill in that control before the form will successfully submit.

Publishing your website - Learn web development
all registrars will have a feature to allow you to check if the domain name you want is available.
...the available feature set will be limited, but it might be perfect for your first experiments.
... there are also free services available like neocities, blogger, and wordpress.
... cheap or free static website hosting by scott murray has some useful ideas on available services.

Graceful asynchronous programming with Promises - Learn web development
there is no guarantee of exactly when the operation will complete and the result will be returned, but there is a guarantee that when the result is available, or the promise fails, the code you provide will be executed in order to do something else with a successful result, or to gracefully handle a failure case.
...so instead of waiting for the user, getting the chosen devices enabled, and directly returning the mediastream for the stream created from the selected sources, getusermedia() returns a promise which is resolved with the mediastream once it's available.
... we immediately run the blob() method on this response to ensure that the response body is fully downloaded, and when it is available transform it into a blob object that we can do something with.
...previously you'd have to include the same code in both the .then() and .catch() callbacks, for example: mypromise .then(response => { dosomething(response); runfinalcode(); }) .catch(e => { returnerror(e); runfinalcode(); }); in more recent modern browsers, the .finally() method is available, which can be chained onto the end of your regular promise chain allowing you to cut down on code repetition and do things more elegantly.

Cooperative asynchronous JavaScript: Timeouts and intervals - Learn web development
previous overview: asynchronous next this tutorial looks at the traditional methods javascript has available for running code asychronously after a set time period has elapsed, or at a regular interval (e.g.
...depending on how processor-intensive these operations are, they can delay your async code even further, as any async code will execute only after the main thread is available.
...in all cases, requestanimationframe() will always do the best it can with what it has available.
... interestingly, it is available in internet explorer 10 and above.

Functions — reusable blocks of code - Learn web development
for now, we just wanted to clear up any possible confusion of method versus function — you are likely to meet both terms as you look at the available related resources across the web.
...you generally use an anonymous function along with an event handler, for example the following would run the code inside the function whenever the associated button is clicked: const mybutton = document.queryselector('button'); mybutton.onclick = function() { alert('hello'); } the above example would require there to be a <button> element available on the page to select and click.
...output() itself is available from anywhere, as it is defined in the global scope.
...these work fine because even though the output() calls are not in the same scope as x is defined in, x is a global variable so is available inside all code, everywhere.

Manipulating documents - Learn web development
using methods available on this object you can do things like return the window's size (see window.innerwidth and window.innerheight), manipulate the document loaded into that window, store data specific to that document on the client-side (for example using a local database or other storage mechanism), attach an event handler to the current window, and more.
...inside your script element, add the following line: const link = document.queryselector('a'); now we have the element reference stored in a variable, we can start to manipulate it using properties and methods available to it (these are defined on interfaces like htmlanchorelement in the case of <a> element, its more general parent interface htmlelement, and node — which represents all nodes in a dom).
... there are older methods available for grabbing element references, such as: document.getelementbyid(), which selects an element with a given id attribute value, e.g.
...the window object has an event available on it called resize, which is fired every time the window is resized — let's access that via the window.onresize event handler and rerun our sizing code each time it changes.

Video and Audio APIs - Learn web development
in the next section we'll look at the basic tools we have available to do this.
...this interface is available to both <audio> and <video> elements, as the features you'll want to implement are nearly identical.
...the htmlmediaelement api makes a wealth of functionality available for creating simple video and audio players, and that's only the tip of the iceberg.
... because <audio> elements have the same htmlmediaelement functionality available to them, you could easily get this player to work for an <audio> element too.

Basic math in JavaScript — numbers and operators - Learn web development
this is especially true when we are learning to program javascript (or any other language for that matter) — so much of what we do relies on processing numerical data, calculating new values, and so on, that you won't be surprised to learn that javascript has a full-featured set of math functions available.
... useful number methods the number object, an instance of which represents all standard numbers you'll use in your javascript, has a number of useful methods available on it for you to manipulate numbers.
... we don't cover these in detail in this article because we wanted to keep it as a simple introduction and only cover the real basic essentials for now; however, once you've read through this module a couple of times it is worth going to the object reference pages and learning more about what's available.
... note that you can quite happily use other variables on the right hand side of each expression, for example: let x = 3; // x contains the value 3 let y = 4; // y contains the value 4 x *= y; // x now contains the value 12 note: there are lots of other assignment operators available, but these are the basic ones you should learn now.

JavaScript object basics - Learn web development
so when you used string methods like: mystring.split(','); you were using a method available on an instance of the string class.
... every time you create a string in your code, that string is automatically created as an instance of string, and therefore has several common methods and properties available on it.
... when you accessed the document object model using lines like this: const mydiv = document.createelement('div'); const myvideo = document.queryselector('video'); you were using methods available on an instance of the document class.
...again, this means that it has several common methods and properties available on it.

Multimedia: Images - Learn web development
this requires the source to be available as in a vector graphic format.
...available to use in the online image optimization tool squoosh.
... other formats improve on jpeg's capabilities in regards to compression, but are not available on every browser: webp — created by google and nowadays supported by all major browsers except safari.
... jpeg-xr — created by microsoft and only available in internet explorer and edgehtml based edge.

Ember interactivity: Events, classes and state - Learn web development
we can define what is available inside this by generating a component class to go along with your component.
... first add another import statement below the previous one, to make actions available inside the service: import { action } from '@ember/object'; update the existing export default class tododataservice extends service { … } block as follows: export default class tododataservice extends service { @tracked todos = []; @action add(text) { let newtodo = new todo(text); this.todos = [...this.todos, newtodo]; } } here, the todos property on the service will main...
...to do this, add the following import line to header.js, beneath the two existing import lines: import { inject as service } from '@ember/service'; with this import in place, we can now make the todo-data service available inside the headercomponent class via the todos object, using the @service decorator.
...to put this in action, go to your todo-list.hbs component, and replace the static component calls: <todo /> <todo /> with a dynamic #each block (which is basically syntactic sugar over the top of javascript's foreach()) that creates a <todo /> component for each todo available in the list of todos returned by the service’s all() getter: {{#each this.todos.all as |todo|}} <todo @todo={{todo}} /> {{/each}} another way to look at this: this — the rendering context / component instance.

Introduction to client-side frameworks - Learn web development
does the framework have a strong community and good docs (and other support) available?
...it is not just about the community's size, but also how welcoming and inclusive it is, and how good available documentation is.
...currently, there are several years of data available, allowing you to get a sense of a framework's popularity.
...a handful of powerful options are now available, such as hugo, jekyll, eleventy, and gatsby.

TypeScript support in Svelte - Learn web development
repl unfortunately, typescript support is not yet available in the repl.
... there is work in progress to support typescript in svelte projects in several code editors; the most complete support so far is available in the svelte for vs code extension, which is developed and maintained by the svelte team.
... repl as we said earlier, typescript is not yet available in the repl.
...we will also see which resources are available online to go further with learning svelte.

Deployment and next steps - Learn web development
you can also consult the svelte api docs and the available examples.
...you also have the interactive slides available here which are, unsurprisingly, built with svelte.
... other learning resources there's a complete course about svelte and sapper by rich harris, available at frontend masters.
... even though svelte is a relatively young project there are lots of tutorials and courses available on the web, so it's difficult to make a recommendation.

Handling common HTML and CSS problems - Learn web development
the w3c has a css validator available too, for this purpose.
...github's atom code editor for example has a rich plugin ecosystem available, with many linting options.
... other popular editors have similar linting packages available.
... this sounds like a pain to deal with, but fortunately there is a polyfill available that does the necessary fixes for you, and more besides — see html5shiv for all the details (see manual installation for the simplest usage).

Setting up your own test automation environment - Learn web development
most popular environments have available a package or framework that will install webdriver and the bindings required to communicate with webdriver using this language, for example, java, c#, ruby, python, javascript (node), etc.
...you can find details of where to get them from on the selenium-webdriver page (see the table in the first section.) obviously, some of the browsers are os-specific, but we're going to stick with firefox and chrome, as they are available across all the main oses.
...you can feel free to change the references to some of the other browsers we added, remove them, etc., depending on what browsers you have available to test on your operating system.
... if you now go back to your browserstack automation dashboard page, you should see your test session available, as before, but with the updated data attached to it: sauce labs getting selenium tests to run remotely on sauce labs is also very simple, and very similar to browserstack albeit with a few syntactic differences.

Introducing a complete toolchain - Learn web development
in this case study we'll look at adding tests to your code, and deploying your app using netlify so it is available for all the web to see.
...git is currently the most popular source code revision control tool available to developers — revision control provides many advantages, such as a way to backup your work in a remote place, and a mechanism to work in a team on the same project without fear of overwriting each other's code.
... web development linting tools mostly exist for javascript (though there are a few available for html and css).
...sass was one of the first preprocessors to support nesting (if not the first) but now after many years, nesting looks like it will soon be standardised, which means that we will have it available in our browsers without needing build tools.

Accessibility Features in Firefox
in fact, the same keyboard commands are still available, so users can become comfortable and productive right away.
...basic screen reader accessibility is available via the fire vox extension.
...custom searches can be added to this quick search bar and the user can switch between them by choosing from a drop down available via the standard alt+down arrow key combination.
...for example, prefs.js gives access to a large number of configuration options not available in the preferences window.

Debugging JavaScript
(note that before firefox 28, this was labeled "browser debugger" and only the debugger was available, not the whole toolbox.) note that you must accept the incoming connection : (you may disable the pop-up above with the devtools.debugger.prompt-connection set to false in about:config.
... this can be a security risk, especially if you also set the devtools.debugger.force-local preference to false.) then, the browser toolbox displays the available tools for debugging.
... (note that before firefox 28, only the script debugger was available.) the use of these tools are the same as the built-in tools.

mach
if you don't use mach, you have to find another solution for the following problems: discovering what commands or make targets are available (mach exposes everything through mach help while inside "mozilla-central" , else you'll just get a cryptic error message) making more sense out of command output (mach offers terminal colorization and structured logging) getting productive tools in the hands of others (mach "advertises" tools to people through mach help (unless it actually just gives you a cryptic error message) - in the former...
...to see the list of the 4 available settings ( which are: alias , test , try , runprefs ) type : $ ./mach settings should i implement x as a mach command?
... yes, the mach core is in mozilla-central inside the python/mach directory and available on pypi at https://pypi.python.org/pypi/mach/.

Introduction to the DOM - Web APIs
alert(paragraphs[0].nodename); all of the properties, methods, and events available for manipulating and creating web pages are organized into objects (for example, the document object that represents the document itself, the table object that implements the special htmltableelement dom interface for accessing html tables, and so forth).
...the page content is stored in the dom and may be accessed and manipulated via javascript, so that we may write this approximative equation: api = dom + javascript the dom was designed to be independent of any particular programming language, making the structural representation of the document available from a single, consistent api.
... this following javascript will display an alert when the document is loaded (and when the whole dom is available for use): <body onload="window.alert('welcome to my home page!');"> another example.

Rendering and the WebXR frame animation callback - Web APIs
time available to render each frame this makes using the most of the time available between frames critical.
...this happens when the amount of time it takes to render a frame exceeds the time available between frames, whether because rendering was delayed or because rendering itself took more time than was available.
...the resulting value is the amount of time available for each frame to be rendered in order to not drop the frame.
... your mission, then, is to keep your code tight and lightweight enough that you don't overrrun the time available to you or otherwise cause dropped frames or excessively abuse the main thread.

Background audio processing using AudioWorklet - Web APIs
the example code found on this page is derived from this working example which is available on glitch.
...slider controls are available to allow controlling the gain of both the oscillator and the audio worklet's output.
...oworkletprocessor { constructor() { super(); } process(inputlist, outputlist, parameters) { /* using the inputs (or not, as needed), write the output into each of the outputs */ return true; } }; registerprocessor("my-audio-processor", myaudioprocessor); after the implementation of the processor comes a call to the global function registerprocessor(), which is only available within the scope of the audio context's audioworklet, which is the invoker of the processor script as a result of your call to audioworklet.addmodule().
... in order to ensure the context is usable, this starts by creating the context if it's not already available, then adds the module containing the processor to the worklet.

Box alignment in Flexbox - CSS: Cascading Style Sheets
the amount of space required to lay out the items is calculated, and the leftover space is then available for distribution.
...a margin set to auto will absorb all available space in its dimension.
...by setting the left and right margin to auto, both sides of our block try to take up all of the available space and so push the box into the center.
...as soon as there is no space available for the auto margin, the item behaves in the same way as all the other flex items and shrinks to try to fit into space.

CSS Box Alignment - CSS: Cascading Style Sheets
fallback alignment if you set an alignment that cannot be fulfilled, then the fallback alignment will come into play and deal with the available space.
...working in a horizontal top to bottom writing mode such as english, with flex-direction as row the items start on the far left and any available space after displaying the items is placed after the items.
... if you set justify-content: space-between on the flex container, the available space is now shared out and placed between the items.
... there needs to be space available in the dimension you wish to align the items in, in order for these keywords to take effect.

Variable fonts guide - CSS: Cascading Style Sheets
the advantage in choosing the variable font is that you have access to the entire range of weights, widths, and styles available, rather than being constrained to only the few that you previously would have loaded separately.
...however, the w3c’s intent was for this syntax not to be used when other attributes are available.
... therefore wherever possible, the appropriate property should be used, with the lower-level syntax of font-variation-settings only being used to set values or axes not available otherwise.
... using a variable font: @font-face changes the syntax for loading variable fonts is very similar to any other web font, with a few notable differences, which are provided via upgrades to the traditional @font-face syntax now available in modern browsers.

Relationship of grid layout to other layout methods - CSS: Cascading Style Sheets
these items are sharing the available space and not lining up underneath the items above.
...if the items wrap onto a new line, they will work out their spacing based on their size and the available space on that line.

font-family - CSS: Cascading Style Sheets
you should always include at least one generic family name in a font-family list, since there's no guarantee that any given font is available.
...rather, font selection is done one character at a time, so that if an available font does not have a glyph for a needed character, the latter fonts are tried.
... (however, this doesn't work in internet explorer 6 or earlier.) when a font is only available in some styles, variants, or sizes, those properties may also influence which font family is chosen.
... <generic-name> generic font families are a fallback mechanism, a means of preserving some of the style sheet author's intent when none of the specified fonts are available.

Audio and Video Delivery - Developer guides
the audio and video elements whether we are dealing with pre-recorded audio files or live streams, the mechanism for making them available through the browser's <audio> and <video> elements remains pretty much the same.
... the main mechanism is outlined below: navigator.mediadevices.getusermedia({audio:true}) .then(function onsuccess(stream) { var recorder = new mediarecorder(stream); var data = []; recorder.ondataavailable = function(e) { data.push(e.data); }; recorder.start(); recorder.onerror = function(e) { throw e.error || new error(e.name); // e.name is ff non-spec } recorder.onstop = function(e) { var audio = document.createelement('audio'); audio.src = window.url.createobjecturl(new blob(data)); } settimeout(function() { rec.stop(); }, 5000); })...
...adaptive streaming media means that the bandwidth and typically quality of the stream can change in real-time in reaction to the user's available bandwidth.
... you can use the element's seekable property to determine the ranges of the media that are currently available for seeking to.

<audio>: The Embed Audio element - HTML: Hypertext Markup Language

Planned changes to shared memory - JavaScript
for top-level documents, two headers will need to be set: cross-origin-opener-policy with same-origin as value (protects your origin from attackers) cross-origin-embedder-policy with require-corp as value (protects victims from your origin) with these two headers set, postmessage() will no longer throw for sharedarraybuffer objects and shared memory across threads is therefore available.
... api changes as a result of this newly required environment, there are a couple api implications: the atomics object is always available.
... sharedarraybuffer objects are in principle always available, but unfortunately the constructor on the global object is hidden, unless the two headers mentioned above are set, for compatibility with web content.
... to avoid having to check whether postmessage() throws, self.crossoriginisolated is being standardized (a getter that returns a boolean; true if the headers are set), available in window and worker contexts.

Populating the page: how browsers work - Web Performance
render time is key, with ensuring the main thread can complete all the work we throw at it and still always be available to handle user interactions.
...as this happens, the preload scanner will parse through the content available and request high priority resources like css, javascript, and web fonts.
...if the load includes javascript, that was correctly deferred, and only executed after the onload event fires, the main thread might be busy, and not available for scrolling, touch, and other interactions.
...if the main thread is occupied parsing, compiling, and executing javascript, it is not available and therefore not able to responsd to user interactions in a timely (less than 50ms) fashion.

Basic native form controls - Learn web development
next we will look at the functionality of the different form controls, or widgets, in detail — studying all the different options available to collect different types of data.
... in this particular article we will look at the original set of form controls, available in all browsers since the early days of the web.
... objective: to understand in detail the original set of native form widgets available in browsers for collecting data, and how to implement them using html.

Other form controls - Learn web development
and browsers that support <datalist>s and <input type="color"> should display a customized palette of colors as the default, while still making the full color palette available.
... summary as you'll have seen in the last few articles, there are a lot of different types of available form element.
... now that you have a grasp of the html behind the different available form controls, we'll take a look at styling them.

Advanced text formatting - Learn web development
ime the user updates the text area code textarea.onkeyup = function(){ // we only want to save the state when the user code is being shown, // not the solution, so that solution is not saved over the user code if(solution.value === 'show solution') { userentry = textarea.value; } else { solutionentry = textarea.value; } updatecode(); }; quotations html also has features available for marking up quotations; which element you use depends on whether you are marking up a block or inline quotation.
...if you want to make the source of the quotation available on the page you need to make it available in the text via a link or some other appropriate way.
...for example: <p>my birthday is on the 25^th of may 2001.</p> <p>caffeine's chemical formula is c₈h₁₀n₄o₂.</p> <p>if x² is 9, x must equal 3 or -3.</p> the output of this code looks like so: representing computer code there are a number of elements available for marking up computer code using html: <code>: for marking up generic pieces of computer code.

Creating hyperlinks - Learn web development
hyperlinks allow us to link documents to other documents or resources, link to specific parts of documents, or make apps available at a web address.
...for example, if an index.html page is uploaded to a directory called projects that sits inside the root of a web server, and the web site's domain is http://www.example.com, the page would be available at http://www.example.com/projects/index.html (or even just http://www.example.com/projects/, as most web servers just look for a landing page such as index.html to load if it isn't specified in the url.) an absolute url will always point to the same location, no matter where it's used.
...if the pdf was available in a subdirectory inside projects called pdfs, the relative link would be pdfs/project-brief.pdf (the equivalent absolute url would be http://www.example.com/projects/pdfs/project-brief.pdf.) a relative url will point to different places depending on the actual location of the file you refer from — for example if we moved our index.html file out of the projects directory and into the root of the web site (th...

Introducing asynchronous JavaScript - Learn web development

...that means that the following (pseudocode) wouldn't work: let response = fetch('myimage.png'); let blob = response.blob(); // display your image blob in the ui somehow that's because you don't know how long the image will take to download, so when you come to run the second line it will throw an error (possibly intermittently, possibly every time) because the response is not yet available.
... the catch() block at the end runs if any of the .then() blocks fail — in a similar way to synchronous try...catch blocks, an error object is made available inside the catch(), which can be used to report the kind of error that has occurred.

Implementing feature detection - Learn web development
let's recap and look at the example we touched on in our handling common javascript problems — the geolocation api (which exposes available location data for the device the web browser is running on) has the main entry point for its use, a geolocation property available on the global navigator object.
... @supports also has or and not logic available — the other block applies the float layout if the flexbox properties are not available: @supports not (flex-flow: row) and (flex: 1) { /* rules in here */ } this may look a lot more convenient than the previous example — we can do all of our feature detection in css, no javascript required, and we can handle all the logic in a single css file, cutting down on http requests.
...it does this by making the global modernizr object available to the page it is applied to, which contains results of the feature detects as true/false properties.

CustomizableUI.jsm
this module is only available from firefox 29 onwards.
... it is available in the firefox window as the customizableui property on the window.
...this matters because of course xul-provided widgets could be available in some windows but not others, and likewise api-provided widgets might not exist in a private window (because of the showinprivatebrowsing property).

DownloadTarget
it is possible for this property to have a non-zero value even if the target file no longer exists, if the value is available in download metadata.
... if that metadata is no longer available and the file has been deleted, then this value is zero.
... for single-file downloads, this property's value will always match the actual size of the file on disk, while the download.totalbytes property, when available, may indicate the size of the data as encoded for transfer instead.

... onbeforesendheaders this event is triggered before sending any http data, but after all http headers are available.

Localization content best practices
don't reuse strings in different contexts this is particularly important for mobile, where different context often means different font and available space for the string.
... gecko and mozilla-central first, make sure that there are no hard-coded strings, and all strings are available in localization files (.dtd, .properties).
...for example, to check if it's using a character not available in the original string, given entities "usebookmark.label" and "usebookmark.accesskey", if you change to "choosebookmark.label" due to a string change, change the access key entity to "choosebookmark.accesskey" to match it.

What every Mozilla translator should know
l10n stands for localization = l + another 10 letters + n mailing lists and other resources there are several mailing lists to keep the track of what's going on, which are available as newsgroups, as well, both on news.mozilla.org and google groups: the main l10n list also available as mozilla.dev.l10n, .l10n in short.
... planning list also available as mozilla.dev.planning, .planning in short.
...in this case the resultant installable file will be available in the mozilla ftp servers: firefox nightly builds thunderbird nightly builds qa (quality assurance) in order to assure the quality of a build we should make some tests using http://litmus.mozilla.org ...

Nonblocking IO In NSPR
fundamentally, this constraint is due to the fact that nonblocking i/o and <tt>select()</tt> are only available to sockets on some platforms (e.g., winsock).
... pr_available() when <tt>pr_available()</tt> returns 0, it may mean one of two things: there is no data available for reading on that socket.
...if <tt>pr_poll()</tt> reports that the socket is readable (i.e., <tt>pr_poll_read</tt> is set in <tt>out_flags</tt>), and <tt>pr_available()</tt> returns 0, this means that the socket connection is closed.

Introduction to NSPR
the communication available is a semantic-free notification whose context must be supplied by the programmer.
... for example, suppose the defined rule of a function is that it should wait until there is an object available and that it should return a reference to that object.
...in addition to these annotated html versions, the same samples are available in pure source form.

...if no new sessions are available, the one read-only session is used, and the state is saved and restored after each multipart operation.
...other certificates on the token are also loaded (to allow building certificate chains), but it's not necessary to include the full chain, as long as the full chain is available in the regular certificate database.

TLS Cipher Suite Discovery
they must agree on these items: key establishment algorithm (such as rsa, dh, or ecdh) peer authentication algorithm (such as rsa, dsa, ecdsa) bulk data encryption algorithm (such as rc4, des, aes) and key size digest algorithm for message authentication checking (sha1, sha256) there are numerous available choices for each of those categories, and the number of possible combinations of all those choices is large.
...when a new version of a tls implementation is made available for use by applications, those applications may wish to immediately use the newly supported cipher suites found in the new version, without the application needing to be modified and re-released to know about these new cipher suites.
...the size of this table varies from release to release, and so libssl makes the number of entries in that table publicly available too.
