The building blocks of responsive design - Progressive web apps (PWAs)
border-box sizing the padding does not affect the overall width and height of the containers because we have set the box-sizing of all elements to border-box: *, *:before, *:after { -webkit-box-sizing: border-box; -moz-box-sizing: border-box; box-sizing: border-box; } this basically means that width and height will now set the dimensions of an element all the way up to and including the border, not just the content.
...this is pretty horrible, but generally this kind of problem is easily fixed with some simple css: img, video { max-width: 100%; } this tells the replaced elements to remain constrained inside their container's widths, no matter what.
...in the snapshot example, we ended up with slightly different code: x-card:nth-child(1) video, x-card:nth-child(2) img { width: 100%; … } this is because in our case, we do in fact want the video and image to stretch to always fill their containers no matter what — a subtle but important difference from max-width — and therefore always be the same size.

... firefox settled on this because web developers mostly seemed to be using the -webkit- prefixed version, so it was better for compatibility.

...in this case, before each comma we write: a media condition ((max-width:600px)) — you'll learn more about these in the css topic, but for now let's just say that a media condition describes a possible state that the screen can be in.
...at this point, if a supporting browser with a viewport width of 480px loads the page, the (max-width: 600px) media condition will be true, and so the browser chooses the 480px slot.

Legacy layout methods - Learn web development
first, of all, apply the following to your html to provide some basic setup: body { width: 90%; max-width: 900px; margin: 0 auto; } the body will be 90% of the viewport wide until it gets to 900px wide, in which case it will stay fixed at this width and center itself in the viewport.
...cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus.</p> </div> body { width: 90%; max-width: 900px; margin: 0 auto; } div:nth-of-type(1) { width: 48%; float: left; } div:nth-of-type(2) { width: 48%; float: right; } you'll notice here that we are using percentages for all the widths — this is quite a good strategy, as it creates a liquid layout, one that adjusts to different screen sizes and keeps the same proportions for the column widths at smaller screen sizes.
... update the second css rule (with the .wrapper selector) as follows: body { width: 90%; max-width: 980px; margin: 0 auto; } .wrapper { padding-right: 2.08333333%; } not only have we given it a percentage width, we have also added a max-width property in order to stop the layout becoming too wide.

Creating reftest-based unit tests
e and run: ./mach reftest if you want to run a particular set of reftests, pass the path as an argument: ./mach reftest path/from/sourcedir/reftest.list and to run a single reftest just pass the path to the test file (not the reference file): ./mach reftest path/from/sourcedir/reftest-name.html there is no reftest equivalent to mach mochitest --keep-open, but temporarily adding the reftest-wait class to a test (or disabling the script that removes it) will keep it open longer.
...first you need to add class="reftest-wait" to the root element in the test to tell the reftest framework not to check the rendering as soon as the test finishes loading and moving on to the next test.
...third, you need to remove 'reftest-wait' from the root element's 'class' attribute to tell the reftest framework that the test is now ready to have its rendering tested.

...you can also use the corresponding css properties, min-width, min-height, max-width and max-height.
... examples of setting widths and heights <button label="1" style="width: 100px;"/> <button label="2" style="width: 100em; height: 10px;"/> <button label="3" flex="1" style="min-width: 50px;"/> <button label="4" flex="1" style="min-height: 2ex; max-width: 100px"/> <textbox flex="1" style="max-width: 10em;"/> <description style="max-width: 50px">this is some boring but simple wrapping text.</description> example 1 the first button will be displayed with a width of 100 pixels (px means pixels).

Introduction to Public-Key Cryptography - Archive of obsolete content
solving this problem requires some way for a user to log in once, using a single password, and get authenticated access to all network resources that user is authorized to use-without sending any passwords over the network.
...a user can log in once, using a single password to the local client's private-key database, and get authenticated access to all ssl-enabled servers that user is authorized to use-without sending any passwords over the network.
...object signing uses standard techniques of public-key cryptography to let users get reliable information about code they download in much the same way they can get reliable information about shrink-wrapped software.
...if you want to get a commercial license for an eighteen-wheeler, the requirements are much more stringent.

Debugging CSS - Learn web development
in the rendered dom the browser may have corrected some badly-written html for you.
...in the css we have applied: em { color: hotpink; font-weight: bold; } above that in the stylesheet however is a rule with a .special selector: .special { color: orange; } as you will recall from the lesson on cascade and inheritance where we discussed specificity, class selectors are more specific than element selectors, and so this is the value that applies.
...if you are becoming frustrated, take a step away from the issue for a while — go for a walk, grab a drink, chat to a co-worker, or work on some other thing for a while.

Sizing items in CSS - Learn web development
a common use of max-width is to cause images to scale down if there is not enough space to display them at their intrinsic width while making sure they don't become larger than that width.
... if you instead use max-width: 100%, the image is able to become smaller than its intrinsic size, but will stop at 100% of its size.
...the second image has max-width: 100% set on it and therefore does not stretch to fill the container.
... the third box contains the same image again, also with max-width: 100% set; in this case you can see how it has scaled down to fit into the box.
Flexbox - Learn web development
have a look at our flexbox-wrap0.html example, and try viewing it live (take a local copy of this file now if you want to follow along with this example): here we see that the children are indeed breaking out of their container.
... one way in which you can fix this is to add the following declaration to your <section> rule: flex-wrap: wrap; also, add the following declaration to your <article> rule: flex: 200px; try this now; you'll see that the layout looks much better with this included: we now have multiple rows — as many flexbox children are fitted onto each row as makes sense, and any overflow is moved down to the next line.
... flex-flow shorthand at this point it is worth noting that a shorthand exists for flex-direction and flex-wrap — flex-flow.
... so for example, you can replace flex-direction: row; flex-wrap: wrap; with flex-flow: row wrap; flexible sizing of flex items let's now return to our first example, and look at how we can control what proportion of space flex items take up compared to the other flex items.

...for this to work reliably though, you still need to build using slow -j1 -w builds, so that make outputs non-interleaved "entering"/"leaving" lines.
...one suggested configuration for building gdb is '--prefix="$home" --disable-debug --with-python=/usr' (create an optimized build with support for python (so that you can use python to much better control when you break etc.), and install it in $home/bin).
... on mac, create a script called something like open-my-workspace.py, give it the following contents, replacing the bold paths as appropriate, and make it executable (chmod a+x open-my-workspace.py): #!/usr/bin/env python import os, subprocess eclipse_app_path = "path/to/eclipse.app/contents/macos/eclipse" workspace_path = os.path.join(os.environ['home'], "home/relative/path/to/the/directory/of/the/workspace/you/want/to/open") subprocess.popen([eclipse...
CustomizableUI.jsm
note that these are also abstract cross-window objects; customizableui will manage the actual dom manipulation involved with adding/moving/removing widgets in all windows for you.

...rough: 'always', removable: 'true', sdkstylewidget: 'true', overflows: false }; for (var p in props) { toolbaritem.setattribute(p, props[p]); } toolbaritem.appendchild(image); return toolbaritem; } }); when you want to remove this widget run this code: customizableui.destroywidget('navigator-throbber-id-within-customizableui-object'); custom type - involved the browser uses type custom for its zoom controls and edit controls in the panel.

similarly, when adding types to jsbuiltins.h, remember to use _js_ptr for pointer-width values.

... // in the calling code var args = { param1: true, param2: 42 }; args.wrappedjsobject = args; var watcher = components.classes["@mozilla.org/embedcomp/window-watcher;1"] .getservice(components.interfaces.nsiwindowwatcher); watcher.openwindow(null, url, windowname, features, args); // in the window code var args = window.arguments[0].wrappedjsobject; this uses the wrappedjsobject trick.
Applying styles and colors - Web APIs
however, the leftmost and all other odd-integer-width thickness lines do not appear crisp, because of the path's positioning.
... note: be aware that in our vertical line example, the y position still referenced an integer gridline position—if it hadn't, we would see pixels with half coverage at the endpoints (but note also that this behavior depends on the current linecap style whose default value is butt; you may want to compute consistent strokes with half-pixel coordinates for odd-width lines, by setting the linecap style to square, so that the outer border of the stroke around the endpoint will be automatically extended to cover the whole pixel exactly).
... for even-width lines, each half ends up being an integer amount of pixels, so you want a path that is between pixels (that is, (3,1) to (3,5)), instead of down the middle of pixels.
...a 1.0-width vertical line drawn at the correct position will become a crisp 2-pixel line when scaled up by 2, and will appear at the correct position.

Getting started with CSS - Learn web development
add the following to your css file: .special { color: orange; font-weight: bold; } save and refresh to see what the result is.
... sometimes you will see rules with a selector that lists the html element selector along with the class: li.special { color: orange; font-weight: bold; } this syntax means "target any li element that has a class of special".
... if you were to do this then you would no longer be able to apply the class to a <span> or another element by simply adding the class to it; you would have to add that element to the list of selectors: li.special, span.special { color: orange; font-weight: bold; } as you can imagine, some classes might be applied to many elements and you don't want to have to keep editing your css every time something new needs to take on that style.
How can we design for all types of users? - Learn web development
this article lists the most important quick-wins for universal design.
...we can style the div either to set its width (using the width property) or its maximum width so that it never gets too large (using the max-width property).
... if you want an elastic/responsive website, and you don't know what the browser's default width is, you can use the max-width property to allow up to 70 characters per line and no more: div.container { max-width:70em; } alternative content for images, audio, and video websites often include stuff besides plain text.

Server-side web frameworks - Learn web development
by contrast, flask is a much lighter-weight framework and is great for creating web apps running on embedded devices.
...get it yourself: some web frameworks include tools/libraries that address every problem their developers can think "by default", while more lightweight frameworks expect web developers to pick and choose solution to problems from separate libraries (django is an example of the former, while flask is an example of a very light-weight framework).
...like many microsoft products it benefits from excellent tools (often free), an active developer community, and well-written documentation.

Configuring Build Options
ac_add_options --with-l10n-base=/path/to/base/dir tbd.
...after enabling the crash reporter in your local build, you will need to run mach with the --enable-crash-reporter (note the extra dash) to enable it at runtime, like so: `./mach run --enable-crash-reporter` ac_add_options --enable-warnings-as-errors this makes compiler warnings into errors which fail the build.
... ac_add_options --with-ccache=/path/to/.mozbuild/sccache/sccache this enables sccache to speed up builds.
ESLint
setting up eslint ./mach eslint --setup running eslint eslint can be run via: ./mach lint -l eslint you can limit running it to a specific directory with: ./mach lint -l eslint browser/components or work directory changes: ./mach lint -l eslint -w or outgoing commits only: ./mach lint -l eslint -o see ./mach eslint --help for more options when running eslint.
... add a line like: /* eslint-env mozilla/browser-window */ or enable the rule in a .eslintrc.js if it will apply to the whole directory.
...ript, or includes items that loaded into content scripts: add a line to tell eslint to use the frame-script environment: /* eslint-env mozilla/frame-script */ my script is a worker: add a line to tell eslint to use the worker environment: /* eslint-env worker */ or, to use a chrome worker environment: /* eslint-env mozilla/chrome-worker */ my file uses chrome/xbl specific globals either, specify the global at the top of the file: /* globals mychromeglobal */ or, add to the global section toolkit/.eslintrc.js if it is widely used.
Patching a Localization
for example, create a directory like localization-workdir (in this example it is located in your home directory): mkdir ~/localization-workdir navigate to the directory you just created.
... cd ~/localization-workdir clone the localization repository for your locale and for the version you want to patch: hg clone http://hg.mozilla.org/releases/l10n/mozilla-aurora/gl now that you have the code and your working directory, edit the dtd and properties files to make your necessary changes.
... cd ~/localization-workdir/gl create a patch (also known as a diff) using the diff command.
Using the viewport meta tag to control layout on mobile browsers
viewport basics a typical mobile-optimized site contains something like the following: <meta name="viewport" content="width=device-width, initial-scale=1"> the width property controls the size of the viewport.
... it can be set to a specific number of pixels like width=600 or to the special value device-width, which is the width of the screen in css pixels at a scale of 100%.
... <meta name="viewport" content="width=device-width, initial-scale=0.86, maximum-scale=3.0, minimum-scale=0.86"> common viewport sizes for mobile and tablet devices if you want to know what mobile and tablet devices have which viewport widths, there is a comprehensive list of mobile and tablet viewport sizes here.

the ssl protocol is defined to be able to handle simultaneous two-way communication between applications at each end of an ssl connection.
... two-way simultaneous communication is also known as "full duplex", abbreviated fdx.
... however, most application protocols that use ssl are not two-way simultaneous, but two-way alternate, also known as "half dupled"; that is, each end takes turns sending, and each end is either sending, or receiving, but not both at the same time.

WebGL best practices - Web APIs
in firefox, setting the pref webgl.perf.max-warnings to -1 in about:config will enable performance warnings that include warnings about fb completeness invalidations.
... consider compressed texture formats while jpg and png are generally smaller over-the-wire, gpu compressed texture formats are smaller on in gpu memory, and are faster to sample from.
...it also adds additional compression that makes basis universal compressed texture files much smaller than regular compressed textures over-the-wire, more comparable to jpeg.
Inputs and input sources - Web APIs
the first question is: are you detecting collisions with virtual objects or terrain, real-world objects or terrain, or both?
... in any case, to identify the targeted object, you need to determine if the ray specified by the xrinputsession property targetrayspace intersects any objects in the scene, whether thye're virtual or real-world.
... incorporating input from non-webxr sources sometimes, you need to have a way to let the user provide input using controllers which are external to webxr.

Window.matchMedia() - Web APIs
WebAPIWindowmatchMedia
examples this example runs the media query (max-width: 600px) and displays the value of the resulting mediaquerylist's matches property in a <span>; as a result, the output will say "true" if the viewport is less than or equal to 600 pixels wide, and will say "false" if the window is wider than that.
... javascript let mql = window.matchmedia('(max-width: 600px)'); document.queryselector(".mq-value").innertext = mql.matches; the javascript code simply passes the media query to match into matchmedia() to compile it, then sets the <span>'s innertext to the value of the results' matches property, so that it indicates whether or not the document matches the media query at the moment the page was loaded.
... css .mq-value { font: 18px arial, sans-serif; font-weight: bold; color: #88f; padding: 0.4em; border: 1px solid #dde; } result see testing media queries programmatically for additional code examples.

Introduction to the CSS basic box model - CSS: Cascading Style Sheets
if the box-sizing property is set to content-box (default) and if the element is a block element, the content area's size can be explicitly defined with the width, min-width, max-width, height, min-height, and max-height properties.
... the thickness of the borders are determined by the border-width and shorthand border properties.
... if the box-sizing property is set to border-box, the border area's size can be explicitly defined with the width, min-width, max-width, height, min-height, and max-height properties.
Backwards Compatibility of Flexbox - CSS: Cascading Style Sheets
uc browser, which still supports the 2009 display: box version only with the -webkit- prefix.
... .wrapper { display: -webkit-box; display: -webkit-flex; display: -ms-flexbox; display: flex; } autoprefixer online is a useful way to see which prefixes are recommended, depending on how many versions you wish to go back with browser support.
...the following feature query would include uc browser, which supports feature queries and old flexbox syntax, prefixed: @supports (display: flex) or (display: -webkit-box) { // code for supporting browsers } for more information about using feature queries see using feature queries in css on the mozilla hacks blog.
Controlling Ratios of Flex Items Along the Main Axis - CSS: Cascading Style Sheets
it gets as big as it possibly can be, taking no soft-wrapping opportunities.
...for example, if i have a 500 pixel-wide container, flex-direction is row, and i have three flex items each 100 pixels wide, then i have 200 pixels of positive free space, which could be distributed between the items if i wanted them to fill the container.
...if i have a 500 pixel-wide container like the one above, but the three flex items are each 200 pixels wide, the total space i need will be 600 pixels, so i have 100 pixels of negative free space.
Mastering Wrapping of Flex Items - CSS: Cascading Style Sheets
making things wrap the initial value of the flex-wrap property is nowrap.
...if you want to cause them to wrap once they become too wide you must add the flex-wrap property with a value of wrap, or use the shorthand flex-flow with values of row wrap or column wrap.
... in the following live example i have a non-wrapped flex container.
Typical use cases of Flexbox - CSS: Cascading Style Sheets
to prevent the image growing too large, add a max-width to the image.
...any width or max-width applied to the image will become the flex-basis.
... .image img { max-width: 100px; } you could also allow both sides to grow and shrink in proportion.
Logical properties for sizing - CSS: Cascading Style Sheets
logical property physical property inline-size width block-size height min-inline-size min-width min-block-size min-height max-inline-size max-width max-block-size max-height width and height example the logical mappings for width and height are inline-size, which sets the length in the inline dimension and block-size, which sets the length in the block dimension.
... min-width and min-height example there are also mappings for min-width and min-height — these are min-inline-size and min-block-size.
... max-width and max-height example finally you can use max-inline-size and max-block-size as logical replacements for max-width and max-height.

A re-introduction to JavaScript (JS tutorial) - JavaScript
this can be important for bit-wise operations.
...conditional statements are supported by if and else; you can chain them together if you like: var name = 'kittens'; if (name == 'puppies') { name += ' woof'; } else if (name == 'kittens') { name += ' meow'; } else { name += '!'; } name == 'kittens meow'; javascript has while loops and do-while loops.
...let's re-write the add function to take as many values as we want: function add() { var sum = 0; for (var i = 0, j = arguments.length; i < j; i++) { sum += arguments[i]; } return sum; } add(2, 3, 4, 5); // 14 that's really not any more useful than writing 2 + 3 + 4 + 5 though.
Loops and iteration - JavaScript
when you use break without a label, it terminates the innermost enclosing while, do-while, for, or switch immediately and transfers control to the following statement.
...ample 2: breaking to a label let x = 0; let z = 0; labelcancelloops: while (true) { console.log('outer loops: ' + x); x += 1; z = 1; while (true) { console.log('inner loops: ' + z); z += 1; if (z === 10 && x === 10) { break labelcancelloops; } else if (z === 10) { break; } } } continue statement the continue statement can be used to restart a while, do-while, for, or label statement.
... when you use continue without a label, it terminates the current iteration of the innermost enclosing while, do-while, or for statement and continues execution of the loop with the next iteration.

writable attribute when the writable property attribute is set to false, the property is said to be “non-writable”.

...however, if a non-writable value property is inherited, it still prevents from modifying the property on the object.

Creating our first Vue component - Learn web development
however, it's important that props serve as one-way data binding — a component should never alter the value of its own props.
...at this point we have a nicely-working todoitem component that can be passed a label to display, will store its checked state, and will be rendered with a unique id each time it is called.
Introducing a complete toolchain - Learn web development
if this is the case, install it using the following command: npm install prettier -g now that prettier is installed, running and tidying your code can be done on the command line on an individual file basis from anywhere on your computer, for example: prettier --write ./src/index.html note: in the command above, i use prettier with the --write flag.
... to get hold of the code files, visit https://github.com/remy/mdn-will-it-miss and download and unzip the contents of this repo onto your local drive somewhere.

The Firefox codebase: CSS Guidelines
do this: border-color: red; not this: border: red; put multiple selectors on different lines do this: h1, h2, h3 { font-family: sans-serif; text-align: center; } not this: h1, h2, h3 { font-family: sans-serif; text-align: center; } naming standards for class names lower-case-with-dashes is the most common.
... 99% theme 70% theme 70% content 99% content font-*, color, *-color, border-*, -moz-appearance [1] line-height, padding, margin cursor, width, max-width, top, bottom [2], etc overflow, direction, display, *-align, align-*, *-box-*, flex-*, order if some css is layout or functionality related, then it is likely content css.
Eclipse CDT Manual Setup
something like $home/eclipse-workspaces/mozilla-tree-1, for example.
... as explained in the code assistance section above, to provide good code assistance eclipse cdt needs to collect build information for the source files by processing a build log from a full, clean build made using -j1 -w.

HTML parser threading
pre-interned attribute and element names hold atoms that are actually app-wide nsstaticatoms.
... since nsstaticatoms are valid app-wide, these atoms work right app-wide on the main thread.

needless to say this is critical for the use of the dom in real-world content.
...this is a real-world case that was used to solve bug 33871 (the patch is not checked in yet, as of writing this document).
Refcount tracing and balancing
perl -w tools/rb/filter-log.pl --object 0x00253ab0 < ./refcounts.log > my-leak.log linux users the log file generated on linux system often lack function names, file names and line numbers.
...for example: perl -w tools/rb/make-tree.pl --object 0x00253ab0 < my-leak.log this will build an indented tree that looks something like this (except probably a lot larger and leafier): .root: bal=1 main: bal=1 dosomethingwithfooandreturnittoo: bal=2 ns_newfoo: bal=1 let's pretend in our toy example that ns_newfoo() is a factory method that makes a new foo and returns it.
NSPR build instructions
--enable-win32-target=win95 this option is only used on windows.
... to generate a "win95" configuration, specify the --enable-win32-target=win95 configure option.

...c++ files from other projects can be preprocessed with gcc -e -wp,-w0,-k.
Renaming With Pork
typically, make cxxflags="-wp,-k,-w0 -save-temps" will work.
... note the -k,-w0 options are passed down to the mcpp preprocessor such that it can annotate files with more precise position information.
SpiderMonkey Build Documentation
if --enable-nspr-build does not work, explicitly tell configure where to find nspr using the --with-nspr-cflags and --with-nspr-libs configure options.
... for example, assuming your local nspr has been installed to c:/mozilla-build/msys/local: /bin/sh ../configure.in --with-nspr-cflags="-ic:/mozilla-build/msys/local/include" \ --with-nspr-libs="c:/mozilla-build/msys/local/lib/libnspr4.a \ c:/mozilla-build/msys/local/lib/libplds4.a \ c:/mozilla-build/msys/local/lib/libplc4.a" if you get symbol loading or dynamic library errors, you can force the correct nspr to load with: path="$path;c:/mozilla-build/msys/local/lib/" ./js specifying installation directories make install puts files in the following directories by default.

Setting up CDT to work on SpiderMonkey
the initial build was in clang, so the modified build commands look like this: mkdir _dbg.obj cd _dbg.obj cc='clang -qunused-arguments -fcolor-diagnostics' cxx='clang++ -qunused-arguments -fcolor-diagnostics' \ ../configure --enable-debug --disable-optimize --enable-debug-symbols note: if you want to use ccache, you can enable it by adding --with-ccache to the arguments list.
... instead, change "build command" to read make -w (this is required because cdt needs detailed information about which directories make operates on, which using -w causes make to provide).
Creating a Python XPCOM component
registering the interface in the "components" directory, execute : ../xpidl -m typelib -w -v -i /usr/share/idl/mozilla/ nsipysimple.idl on windows you must point to the idl directory as part of your mozilla build.
... for example: xpidl.exe -m typelib -w -v -i c:\source\mozilla\obj-i686-pc-mingw32\dist\idl foo.idl xpidl will then create nsipysimple.xpt, which should be placed correctly (e.g., in the 'components' directory).

Element.clientTop - Web APIs
WebAPIElementclientTop
this is because the offsettop indicates the location of the top of the border (not the margin) while the client area starts immediately below the border, (client area includes padding.) therefore, the clienttop value will always equal the integer portion of the .getcomputedstyle() value for "border-top-width".
... (actually might be math.round(parsefloat()).) for example, if the computed "border-top-width" is zero, then clienttop is also zero.

FileSystemEntry.toURL() - Web APIs
if your site is located at http://my-awesome-website.woot, and you have a temporary file system that contains an image file named awesomesauce.jpg, the url returned by tourl() might be (depending on the browser's implementation) something like "filesystem:http://my-awesome-website.woot/temporary/awesomesauce.jpg".
... code that makes use of this might look like this: let img = document.createelement("img"); img.src = imagefileentry.tourl(); document.body.appendchild(img); assuming the scenario mentioned before the code, the result would be html that looks like this being appended to the end of the document: <img src="filesystem:http://my-awesome-website.woot/temporary/awesomesauce.jpg"> browser compatibility the compatibility table on this page is generated from structured data.

A simple RTCDataChannel sample - Web APIs
note: in a real-world scenario in which the two peers aren't running in the same context, the process is a bit more involved; each side provides, one at a time, a suggested way to connect (for example, udp, udp with a relay, tcp, etc.) by calling rtcpeerconnection.addicecandidate(), and they go back and forth until agreement is reached.
... note: once again, this process is not a real-world implementation; in normal usage, there's two chunks of code running on two machines, interacting and negotiating the connection.
WebRTC API - Web APIs
included are interfaces representing peer media connections, data channels, and interfaces used when exchanging information on the capabilities of each peer in order to select the best possible configuration for a two-way media connection.

you must, obtain the value of sec-websocket-key request header without any leading and trailing whitespace link it with "258eafa5-e914-47da-95ca-c5ab0dc85b11" compute sha-1 and base64 code of it write it back as value of sec-websocket-accept response header as part of a http response.
... if (get.find()) { matcher match = pattern.compile("sec-websocket-key: (.*)").matcher(data); match.find(); byte[] response = ("http/1.1 101 switching protocols\r\n" + "connection: upgrade\r\n" + "upgrade: websocket\r\n" + "sec-websocket-accept: " + base64.getencoder().encodetostring(messagedigest.getinstance("sha-1").digest((match.group(1) + "258eafa5-e914-47da-95ca-c5ab0dc85b11").getbytes("utf-8"))) + "\r\n\r\n").getbytes("utf-8"); out.write(response, 0, response.length); decoding messages after a successful handshake, client can send messages to the server, but now these are encoded.

Using bounded reference spaces - Web APIs
it's difficult (and would probably be fairly confusing) to create a virtual world that's larger than the physical space available to the user if you're mapping their real-world movement into the virtual environment.
... because bounded-floor is a floor-bound reference space, the user starts out on the floor of the space, which is sensible given the real-world implications otherwise.
Geometry and reference spaces in WebXR - Web APIs
if the user's xr hardware permits them to move about their real-world space, and you are able to do so, it may be useful to use a bounded-floor reference space, which lets you specifically define the boundaries of the area in which passage is allowed and safe.
...for example, there's simply no way for a basic headset such as a gearvr device to be made to work in an app that requires support for allowing the user to walk around the environment by tracking their real-world movements.
Window.open() - Web APIs
WebAPIWindowopen
always use a real url for the href attribute value so that if javascript support is disabled or inexistent or if the user agent does not support opening of secondary window (like ms-web tv, text browsers, etc), then such user agents will still be able to load the referenced resource according to its default mode of opening/handling a referenced resource.

... (max-width: 24.99em) is simply a poor man's version of not all and (min-width: 25em): do not use (max-width: 24.99em) because the layout might break on very high font sizes on very high definition devices in the future.
CSP: referrer - HTTP
"none-when-downgrade" this is the user agent's default behavior if no policy is specified.
... "origin-when-cross-origin" / "origin-when-crossorigin" send a full url when performing a same-origin request, but only send the origin of the document for other cases.

Meta programming - JavaScript

BigInt - JavaScript
type information when tested against typeof, a bigint will give "bigint": typeof 1n === 'bigint' // true typeof bigint('1') === 'bigint' // true when wrapped in an object, a bigint will be considered as a normal "object" type: typeof object(1n) === 'object' // true operators the following operators may be used with bigints (or object-wrapped bigints): +, *, -, **, %.
...1 : 0)) // ↪ [ -12n, 0, 0n, 4n, 4, 6, 10 ] note that comparisons with object-wrapped bigints act as with other objects, only indicating equality when the same object instance is compared: 0n === object(0n) // false object(0n) === object(0n) // false const o = object(0n) o === o // true conditionals a bigint behaves like a number in cases where: it is converted to a boolean: via the boolean function; when used with logical operators ||, ...
Object.isSealed() - JavaScript
an object is sealed if it is not extensible and if all its properties are non-configurable and therefore not removable (but not necessarily non-writable).
...object.isfrozen(sealed); // === true // (all properties also non-writable) var s2 = object.seal({ p: 3 }); object.isfrozen(s2); // === false // ('p' is still writable) var s3 = object.seal({ get p() { return 0; } }); object.isfrozen(s3); // === true // (only configurability matters for accessor properties) non-object coercion in es5, if the argument to this method is not an object (a primitive), then it will cause a typeerror.
globalThis - JavaScript
unlike similar properties such as window and self, it's guaranteed to work in window and non-window contexts.
... html and the windowproxy in many engines globalthis will be a reference to the actual global object, but in web browsers, due to iframe and cross-window security considerations, it references a proxy around the actual global object (which you can't directly access).
Strict mode - JavaScript
for example, nan is a non-writable global variable.
...any assignment that silently fails in normal code (assignment to a non-writable global or property, assignment to a getter-only property, assignment to a new property on a non-extensible object) will throw in strict mode: 'use strict'; // assignment to a non-writable global var undefined = 5; // throws a typeerror var infinity = 5; // throws a typeerror // assignment to a non-writable property var obj1 = {}; object.defineproperty(obj1, 'x', { value: 42, writable: false }); obj1.x = 9; // throws a typeerror // assignment to a getter-only property var obj2 = { get x() { return 17; } }; obj2.x = 5; // throws a typeerror // assignment to a new prope...

Codecs used by WebRTC - Web media technologies

Mapping the width and height attributes of media container elements to their aspect-ratio - Web media technologies
to keep images from breaking out of their containers when the container becomes narrower than the image, developers started using css like the following: img { max-width: 100%; height: auto; } this is really useful for responsive layouts, but unfortunately it causes the jank problem to return — the above css overrides the width and height attribute information, meaning that if the image has not loaded for some reason, its height will be set to 0.
... when the width/height of an <img> element — as set using html attributes — is overidden using css using something like this: img { max-width: 100%; height: auto } the aspect ratio is then used to calculate the height and therefore the correct size is applied to the <img> element, meaning that the aforementioned jank will not occur when the image loads.
Critical rendering path - Web Performance
on by-default full screen browsers, like your phone's browser, by setting <meta name="viewport" content="width=device-width">, the width will be the width of the device instead of the default viewport width.
... the device-width changes when a user rotates their phone between landscape and portrait mode.
Mobile first - Progressive web apps (PWAs)
to create something more suitable for desktop, i put in the following media queries: @media (min-width: 480px) { #bottom, #top { display: none; } article, nav { display: block; } nav ul { text-align: center; } nav li { display: inline; } nav li a { border-right: 1px solid #ad66d5; border-bottom: none; display: inline-block; padding: 0 5px; font-size: 1.6em; } nav li:last-child a { border-right: none; } } @media (min-wid...
...you could create a block to only load the library in the case of narrow screen devices: if(window.matchmedia("(min-width: 481px)").matches) { require('three'); } we can, therefore, save the bandwidth for browsers that don't need it.

locks "are we holding the runtime-wide gc lock?" is a static yes or no for almost every line of code.
SpiderMonkey Internals: Thread Safety
when this happens, the thread also refills that freelist from the jsruntime-wide gc allocator while it's in the lock.
Tracing JIT
the term deep bail denotes a special case of bailing: when a trace calls a native spidermonkey c function that gets part-way through executing and then forces a trace-exit (possibly due to a nested c function depending on not-yet-flushed state in the trace).
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.
JSCheckAccessOp
if a class leaves the checkaccess field null, a runtime-wide object access callback is called instead; see js_setcheckobjectaccesscallback.
JS_CheckAccess
otherwise, if a runtime-wide check-object-access callback has been installed by calling js_setcheckobjectaccesscallback, then that is called to perform the check.
JS_SetGCCallback
in a js_threadsafe build, the jsgc_end callback is called after each stop-the-world rendezvous during which one or more garbage collection cycles finished.
JS_SetObjectPrincipalsFinder

(for example, a webpage with an advertising-module and statistics-module both monitoring video-watching.) when there are many nested elements, each with its own handler(s), event processing can become very complicated—especially where a parent element receives the very same event as its child elements because "spatially" they overlap so the event technically occurs in both, and the processing order of such events depends on the event bubbling and capture settings of each handler triggere...

Guide to the Fullscreen API - Web APIs
to get the same fullscreen behavior in webkit, you need to add your own "width: 100%; height: 100%;" css rules to the element yourself: #myvideo:-webkit-full-screen { width: 100%; height: 100%; } on the other hand, if you're trying to emulate webkit's behavior on gecko, you need to place the element you want to present inside another element, which you'll make fullscreen instead, and use css rules to adjust the inner element to match the appearance you want.
Fullscreen API - Web APIs
in a real-world deployment, at this time, you'll want to check for prefixed versions of this (mozfullscreenelement, msfullscreenelement, or webkitfullscreenelement, for example).
