CDN - MDN Web Docs Glossary: Definitions of Web-related terms
these servers store duplicate copies of data so that servers can fulfill data requests based on which servers are closest to the respective end-users.

Digest - MDN Web Docs Glossary: Definitions of Web-related terms
a digest can be used to perform several tasks: in non-cryptographic applications (e.g., the index of hash tables, or a fingerprint used to detect duplicate data or to uniquely identify files) verify message integrity (a tampered message will have a different hash) store passwords so that they can't be retrieved, but can still be checked (to do this securely, you also need to salt the password.) generate pseudo-random numbers generate keys it is critical to choose the proper hash function for your use case to avoid collisions and predictability.

UDP (User Datagram Protocol) - MDN Web Docs Glossary: Definitions of Web-related terms
it has no handshaking dialogues, and thus exposes the user's program to any unreliability of the underlying network; there is no guarantee of delivery, ordering, or duplicate protection.

usenet is an internet discussion system where each post is duplicated on many servers.

Organizing your CSS - Learn web development
avoid overly-specific selectors if you create very specific selectors you will often find that you need to duplicate chunks of your css to apply the same rules to another element.

Use JavaScript within a webpage - Learn web development
if you use pointer events (like mouse events or touch events), duplicate the functionality with keyboard events.

Object-oriented JavaScript for beginners - Learn web development
in oop, we can create new classes based on other classes — these new child classes can be made to inherit the data and code features of their parent class, so you can reuse functionality common to all the object types rather than having to duplicate it.

React interactivity: Events and state - Learn web development
update your newtask constant declaration to this: const newtask = { id: "todo-" + nanoid(), name: name, completed: false }; save everything, and try your app again — now you can add tasks without getting that warning about duplicate ids.

Reviewer Checklist
the patch does not add duplicates of existing code ('almost duplicates' could mean a refactor is needed).

Performance
not handling those properly can lead to duplicate or conflicting code execution, especially when messages are sent.

Localization content best practices
if a string is tied to an accesskey or a tooltip, use string ids that highlight this relation: neweventbtn.label = add event neweventbtn.accesskey = a neweventbtn.tooltip = add a new event don't duplicate ids if you're adding new strings, check that you're not duplicating an existing id.

Invariants
even if the function is native, there is serious trouble: js_newobject with null parent argument calculates the parent from cx->fp->scopechain, which can be stale if we're on trace.) the chain of properties starting at any jsshape and chasing jsshape::parent never forms a cycle and does not contain any duplicate jsscopeproperty::slot values other than -1.

Using the Places annotation service
most methods in the service are duplicated with one method labeled as a 'page annotation' taking an nsiuri and the others labeled as an 'item annotation' and taking the id of an item in the places database.

Creating 3D objects using WebGL - Web APIs
{ const vertexcount = 36; const type = gl.unsigned_short; const offset = 0; gl.drawelements(gl.triangles, vertexcount, type, offset); } since each face of our cube is comprised of two triangles, there are 6 vertices per side, or 36 total vertices in the cube, even though many of them are duplicates.

Using Web Workers - Web APIs
the page and worker do not share the same instance, so the end result is that a duplicate is created on each end.

Using the aria-hidden attribute - Accessibility
this can improve the experience for assistive technology users by hiding: purely decorative content, such as icons or images duplicated content, such as repeated text offscreen or collapsed content, such as menus according to the fourth rule of aria, aria-hidden="true" should not be used on a focusable element.

ARIA - Accessibility
the new landmark elements (<main>, <header>, <nav> etc) have built-in aria roles, so there is no need to duplicate them.

Choosing between www and non-www URLs - HTTP
this way, search engines don't index the same page several times, potentially leading to it being considered as duplicate content or spam, and even removing or lowering your page from the search engine result pages.

<mmultiscripts> - MathML
prescripts are optional and are separated by the empty tag <mprescripts/> (only one <mprescripts /> element is allowed, otherwise you will get an duplicatemprescripts error in the error console and "invalid-markup" in your rendering).

<mstyle> - MathML

Digital video concepts - Web media technologies
looking at 4:2:0 chroma subsampling, in the first column, the value 2 indicates that the first row of chroma data has two samples in it; the 0 indicates that the second row has no chroma samples of its own, and that the first row's samples should be duplicated to the second row.
