HTML basics - Learn web development
html consists of a series of elements, which you use to enclose, or wrap, different parts of the content to make it appear a certain way, or act a certain way.
... the main parts of our element are as follows: the opening tag: this consists of the name of the element (in this case, p), wrapped in opening and closing angle brackets.
... note: simple attribute values that don't contain ascii whitespace (or any of the characters " ' ` = < > ) can remain unquoted, but it is recommended that you quote all attribute values, as it makes the code more consistent and understandable.
...marking up lists always consist of at least 2 elements.

Getting started with HTML - Learn web development

receiving data & nsistreamlistener you can read or write, from or to a channel using either the synchronous api, or the asynchronous api.
... if you want to move data asynchronously you need to be able to receive callbacks using an implementation of nsistreamlistener.
... an nsistreamlistener is told when the uri transaction has "started," when data is available (in the case of reading data), and when it has "stopped." it is up to the nsistreamlistener implementation to decide what to do with these various notifications.
... the ondataavailable() notification provides a chance for the nsistreamlistener to actually retrieve data that the channel has acquired.

Tiles and tilemaps overview - Game development
tilemaps are a very popular technique in 2d game development, consisting of building the game world or level map out of small, regular-shaped images called tiles.
... one simple technique consists of pre-rendering the map in a canvas on its own (when using the canvas api) or on a texture (when using webgl), so tiles don't need to be re-drawn every frame and rendering can be done in just one blitting operation.
... one way consists of drawing the section that will be visible off-canvas (instead of the entire map.) that means that as long as there is no scrolling, the map doesn't need to be rendered.

...if you want a more formal relationship, or your definition consists of only one sentence rather than the whole paragraph, you can use the aria-describedby attribute to associate a term more formally with its definition: <p> <span id="ff"> <dfn aria-describedby="ff">firefox</dfn> is the web browser created by the mozilla foundation.

Necko walkthrough
nsdocshell::internalload nsdocshell::douriload opens the nsichannel for the uri (ns_newchannel) if "http:", it will be an nsihttpchannel nsdocshell::dochannelload nsuriloader::openuri passes an nsistreamlistener pointer, 'loader' to nsuriloader::openchannel - it creates an nsdocumentopeninfo object, which implements nsistreamlistener, i.e.
... receive response get a callback to each of these: nsistreamlistener::onstartrequest (header info) nsistreamlistener::ondataavailable (data in single or multiple chunks) nsistreamlistener::onstoprequest (no more data from http) this all happens on the main thread, in a non-blocking fashion: make your request on the main thread, then carry on and get the async response later, also on the main thread.
... these functions call nsistreamlistener::onstartrequest, nsistreamlistener::ondataavailable and nsistreamlistener::onstoprequest respectively.

Proxies in Necko
socks and nsisockettransportservice the aforementioned methods work very well for application-level proxies.
...therefore, nsisockettransportservice supports creating socket transports using an nsiproxyinfo.
...note that socks is implemented as an nsisocketprovider, and the socket transport service will therefore use it as as the downmost socket type.

228 js_defineconstdoubles jsapi reference, spidermonkey js_defineconstdoubles creates one or more properties for a specified object, obj, where each property consists of a double value.
... 537 tracing jit deprecated, spidermonkey the tracing jit in spidermonkey consists of a generic, low level component called nanojit which is co-maintained between adobe and mozilla, and a spidermonkey-specific high level component called jstracer.
...the jstracer component consists of a monitor and a recorder.

SpiderMonkey Internals
the compiler consists of: a random-logic rather than table-driven lexical scanner, a recursive-descent parser that produces an ast, and a tree-walking code generator.
... objects consist of a possibly shared structural description, called the map or scope; and unshared property values in a vector, called the slots.
... the atom manager consists of a hash table associating strings uniquely with scanner/parser information such as keyword type, index in script or function literal pool, etc.

JIT Optimization Outcomes
inconsistentfixedslot the property being accessed is not stored at a known location in the object.
... inconsistentfieldtype the type of an unboxed field is not consistent across all the different types of objects it could be accessed from.
... inconsistentfieldoffset the offset of an unboxed field is not consistent across all the different types of objects it could be accessed from.

... mxr id search for jsclass_private_is_nsisupports jsclass_is_domjsclass added in spidermonkey 17 objects are dom.

JS_InitClass
a jsapi class consists of a jsclass structure, a constructor, a prototype object, and properties and functions.
...this inconsistency can cause problems; for example, if the finalizer calls js_getprivate(), expecting that the constructor called js_setprivate(), it may find that the private data is null.
... the jsclass_construct_prototype flag is one way to avoid this inconsistency.

JS_SetOptions

...if the parser produced no information about the node's source location, the field is null; otherwise it is an object consisting of a start position (the position of the first character of the parsed source region) and an end position (the position of the first character after the parsed source region): interface sourcelocation { source: string | null; start: position; end: position; } each position object consists of a line number (1-indexed) and a column number (0-indexed): interface position { li...
... interface expressionstatement <: statement { type: "expressionstatement"; expression: expression; } an expression statement, i.e., a statement consisting of a single expression.

Web Replay
this ensures that no matter when we create or restore a snapshot, the same set of threads will exist and will have consistent stacks locations.
... locks and condition variables are to some extent system resources, and to avoid problems we make sure each thread is waiting on a consistent variable when saving or restoring a snapshot (see section above).
... this is left alone when restoring a snapshot, so whenever saving or restoring a snapshot they should be in a consistent state for the child process.

Creating a Python XPCOM component
creating applications with mozilla already provides a tutorial for making a simple javascript or c++ component (implementing the nsisimple interface).
...defining the interface make a file named "nsipysimple.idl" to define the interface: #include "nsisupports.idl" [scriptable, uuid(2b324e9d-a322-44a7-bd6e-0d8c83d94883)] interface nsipysimple : nsisupports { attribute string yourname; void write( ); void change(in string avalue); }; this is the same as the nsisimple interface used here.
...for example: % cd c:\mozilla\bin\python\xpcom % python xpt.py nsisample class nsisample: _com_interfaces_ = xpcom.components.interfaces.nsisample # if this object needs to be registered, the following 2 are also needed.

Component Internals
a set of default libraries stored in this components directory makes up a typical gecko installation, providing functionality that consists of networking, layout, composition, a cross-platform user interface, and others.
...it is possible that xpcom will return an error if you access the nsiservicemanager at that point, for example, so you may have to keep a reference-counted pointer to the service you are interested in using during this notification.
...most component libraries only need these two interfaces, along with the nsisupports interface, to have xpcom load, recognize, and use their core object code.

Mozilla internal string guide
you must not access the string except via the handle until you call finish() on the handle in the success case or you let the handle go out of scope without calling finish() in the failure case, in which case the destructor of the handle puts the string in a mostly harmless but consistent state (containing a single replacement character if a capacity greater than 0 was requested, or in the char case if the three-byte utf-8 representation of the replacement character doesn't fit, an ascii substitute).
... mozilla::bulkwritehandle<t> autoconverts to a writable mozilla::span<t> and also provides explicit access to itself as span (asspan()) or via component accessors named consistently with those on span: elements() and length() the latter is not the logical length of the string but the writable length of the buffer.

Interfacing with the XPCOM cycle collector
or ns_decl_cycle_collection_class_ambiguous(nsfoo, nsibar) if nsfoo inherits from multiple interfaces, where nsibar is the interface which is returned when you queryinterface nsfoo to nsisupports.
...for example, your class may have multiple nsisupports base classes, which requires the use of some *_ambiguous macros that perform a disambiguating downcast.
... the main macro for traverse is ns_impl_cycle_collection_traverse: ns_impl_cycle_collection_traverse(msomemember) unlink works similarly: ns_impl_cycle_collection_unlink(msomemember) these macros should handle a variety of cases, such as reference counted pointers to cycle collected nsisupports or non-nsisupports objects, as well as arrays of these pointers.

Components.interfaces
this includes nsisupports.queryinterface(), the optional parameter accepted by nsijscid.getservice(), nsijscid.createinstance() when called from javascript, and nsiclassinfo.getinterfaces().
...you can retrieve an interface object using: var iface = components.interfaces.nsisupportsarray; this will return you the interface object for the nsisupportsarray interface.
...for example, assume we have the following interface declaration: interface nsifoo : nsisupports { const pruint32 myflag = 5; }; the constant myflag can then be accessed using var myflag = components.interfaces.nsifoo.myflag; ...

jsdIStackFrame
private data for this object is an nsisupports object.
...private data for this context, if it is an nsisupports, |null| otherwise.
...this attribute is only valid for contexts which implement nsiscriptcontext.

mozIRegistry
currently, nsiservicemanager requires a clsid to access a service which hardcodes the implementation of that service.
...i think a simple clsid "alias" mechanism (equivalent to com's "component categories" in some respects), along with the ability to "set" services (versus the service manager insisting on creating the services itself) would suffice.
...clients will obtain this interface via the service manager (see mozilla/xpcom/public/nsiservicemanager.h).

Frame rate - Firefox Developer Tools
a low or inconsistent frame rate can make a site appear unresponsive or janky, making for a bad user experience.
... in general, a high and consistent frame rate will make the user's interaction with the site more enjoyable and engaging.
... however, consistency is especially important: if you can't deliver 60fps, it's better to deliver lower frame rates more consistently, and avoid sudden dips in the frame rate which cause the site to freeze.

Animating CSS properties - Firefox Developer Tools
the css rendering waterfall the process the browser uses to update the page when a css property has changed can be described as a waterfall consisting of the following steps: recalculate style: every time a css property for an element changes, the browser must recalculate computed styles.
...with only 16.7ms in our total budget, it's not surprising we are missing a consistently high frame rate.
...we're averaging nearly 60fps, and apart from one dip near the start, we're getting a consistently high frame rate.

Using microtasks in JavaScript with queueMicrotask() - Web APIs
the main reason to use microtasks is simply that: to ensure consistent ordering of tasks, even when results or data is available synchronously, but while simultaneously reducing the risk of user-discernible delays in operations.
... ensuring ordering on conditional use of promises one situation in which microtasks can be used to ensure that the ordering of execution is always consistent is when promises are used in one clause of an if...else statement (or other conditional statement), but not in the other clause.
... we can ensure consistent ordering of these operations by using a microtask in the if clause to balance the two clauses: customelement.prototype.getdata = url => { if (this.cache[url]) { queuemicrotask(() => { this.data = this.cache[url]; this.dispatchevent(new event("load")); }); } else { fetch(url).then(result => result.arraybuffer()).then(data => { this.cache[url] = data; th...

<bdi>: The Bidirectional Isolate element - HTML: Hypertext Markup Language
but if embedded-text is rtl, then - 1 will be treated as rtl text (because it consists of neutral and weak characters).
...n</span> - 1st place</li> <li><span class="name">jerry cruncher</span> - 2nd place</li> </ul> body { border: 1px solid #3f87a6; max-width: calc(100% - 40px - 6px); padding: 20px; width: calc(100% - 40px - 6px); border-width: 1px 1px 1px 5px; } no <bdi> with rtl text this example lists the winners of a competition using <span> elements only, and one of the winners has a name consisting of rtl text.
... in this case the "- 1", which consists of characters with neutral or weak directionality, will adopt the directionality of the rtl text, and the result will be garbled: <ul> <li><span class="name">اَلأَعْشَى</span> - 1st place</li> <li><span class="name">jerry cruncher</span> - 2nd place</li> </ul> body { border: 1px solid #3f87a6; max-width: calc(100% - 40px - 6px); padding: 20px; width: calc(100% - 40px - 6px); border-width: 1px 1px 1px 5px; } using <bdi> with ltr and rtl text this example lists the winners of a competition using <bdi> elements.

<menu> - HTML: Hypertext Markup Language
toolbar: indicates the toolbar state, which represents a toolbar consisting of a series of commands for user interaction.
... context menus consist of a <menu> element which contains <menuitem> elements for each selectable option in the menu, <menu> elements for submenus within the menu, and <hr> elements for separator lines to break up the menu's content into sections.
... toolbar menus consist of a <menu> element whose content is described in one of two ways: either as an unordered list of items represented by <li> elements (each representing a command or option the user can utilize), or (if there are no <li> elements), flow content describing the available commands and options.

<textarea> - HTML: Hypertext Markup Language
setting these is a good idea for consistency, as browser defaults can differ.
... soft: the browser ensures that all line breaks in the value consist of a cr+lf pair, but does not insert any additional line breaks.
... baseline inconsistency the html specification doesn't define where the baseline of a <textarea> is, so different browsers set it to different positions.

HTML documentation index - HTML: Hypertext Markup Language
the attribute value must consist of a single printable character (which includes accented and other characters that can be generated by the keyboard).
...every html element can have an itemprop attribute specified, and an itemprop consists of a name-value pair.

Evolution of HTTP - HTTP
built over the existing tcp and ip protocols, it consisted of 4 building blocks: a textual format to represent hypertext documents, the hypertext markup language (html).
...http/0.9 is extremely simple: requests consist of a single line and start with the only possible method get followed by the path to the resource (not the url as both the protocol, server, and port are unnecessary once connected to the server).
... get /mypage.html the response is extremely simple too: it only consisted of the file itself.

Index - HTTP
an http header consists of its case-insensitive name followed by a colon ':', then by its value (without line breaks).
...these violation reports consist of json documents sent via an http post request to the specified uri.
...these violation reports consist of json documents sent via an http post request to the specified uri.

A typical HTTP session - HTTP
in client-server protocols, like http, sessions consist of three phases: the client establishes a tcp connection (or the appropriate connection if the transport layer is not tcp).
...a client request consists of text directives, separated by crlf (carriage return, followed by line feed), divided into three blocks: the first line contains a request method followed by its parameters: the path of the document, i.e.
...similar to a client request, a server response is formed of text directives, separated by crlf, though divided into three blocks: the first line, the status line, consists of an acknowledgment of the http version used, followed by a status request (and its brief meaning in human-readable text).

Functions - JavaScript
defining functions function declarations a function definition (also called a function declaration, or function statement) consists of the function keyword, followed by: the name of the function.
...the function consists of one statement that says to return the parameter of the function (that is, number) multiplied by itself.
... // choose one and be consistent.

Date.parse() - JavaScript
fall-back to implementation-specific date formats this section contains implementation-specific behavior that can be inconsistent across implementations.

... date.parse("2019-01-01t00:00:00") non-standard date strings this section contains implementation-specific behavior that can be inconsistent across implementations.

Intl - JavaScript
intl.displaynames() constructor for objects that enable the consistent translation of language, region and script display names.

... bcp 47 also allows for extensions, each consisting of a single digit or letter (other than "x") and one or more two- to eight-letter or digit tags, all separated by hyphens.

Digital audio concepts - Web media technologies
while recording or generating multi-channel audio files, the channels are assembled into a series of audio frames, each consisting of one sample for each of the audio's channels.
... audio compression basics unlike text and many other kinds of data, audio data tends to be noisy, meaning the data rarely consists of a series of exactly repeated bytes or byte sequences.
...by manipulating the waveform to make it easier to compress, or by removing components of the sound that aren't really heard, the waveform becomes simpler, resulting in data which has more consistency and is therefore easier to compress.
