    Klipse

    Klipse

    Klipse is a JavaScript plugin for embedding interactive code snippets

    Klipse is a JavaScript plugin for embedding interactive code snippets in tech blogs. Technically, Klipse is a small piece of JavaScript code that evaluates code snippets in the browser and it is pluggable on any web page. The klipse plugin is a JavaScript tag that transforms static code snippets of an HTML page into live and interactive snippets. If you want to integrate Klipse inside a Clojurescript project, it is recommended to consume Klipse as a Clojurescript library like any other Clojurescript lib. The Klipse plugin can be easily styled with CSS, which can be applied both to the Klipse plugin's own elements, and to the CodeMirror editor's elements. Much of the styling you'll apply will be to CodeMirror, as it contains all the CSS classes to style the code itself. Surrounding CodeMirror is the Klipse plugin, the styles of which control the plugin's borders, and the executed code's output.

    Knockoff

    Knockoff

    Chrome extension that filters pseudo-brand junk out of Amazon

    Knockoff is a browser extension that reduces low-trust and pseudo-brand listings while shopping on Amazon. It examines product brands locally and classifies them with personal lists, curated databases, community data, and readable naming heuristics. Users can hide, dim, or label filtered products without permanently removing access to them. Three filtering levels range from blocking known problem brands to allowing only recognized brands. Interactive badges let shoppers trust a brand, block it, reveal an item once, or report an incorrect decision. The extension requires no account, performs no tracking, and makes no server request during the normal shopping path. It supports Amazon marketplaces through Chrome, Firefox, and Safari, although its language heuristics are tuned primarily for English.

    Magnetic

    Browser addon to batch download torrents

    I developed this for my own needs but I don't see why I shouldn't share it! Usage is very easy: * Make sure you have installed an application capable of intercepting magnet: links (see http://en.wikipedia.org/wiki/Comparison_of_BitTorrent_clients#Features_I) * Open at least a magnet link manually and associate a default application to the protocol * Now clicking the addon button will open all magnet links in all open tabs and send them to the torrent client! Let me know if you find any issues, this is my very first mod and is very early in development, it definitely needs more work ;)

    Masonry

    Masonry

    A cascading grid layout plugin

    Masonry is a JavaScript grid layout library. It works by placing elements in optimal position based on available vertical space, sort of like a mason fitting stones in a wall. You’ve probably seen it in use all over the Internet. All sizing and styling of items is handled by your own CSS. tem sizes can be set with percentages for responsive layouts. With the masonry layout mode, set percentage-width columnWidth with element sizing. Set percentPosition: true so item positions are likewise set with percentages to reduce adjustment transitions on window resize. Unloaded images can throw off Masonry layouts and cause item elements to overlap. imagesLoaded resolves this issue. imagesLoaded is a separate script you can download at imagesloaded.desandro.com. Or, initialize Masonry after all images have been loaded.

    Next SEO

    Next SEO

    Next SEO is a plug in that makes managing your SEO easier in Next.js

    Next SEO is a plugin that makes managing your SEO easier in Next.js projects. Pull requests are very welcome. Also make sure to check out the issues for feature requests if you are looking for inspiration on what to add. Feel like supporting this free plugin? It takes a lot of time to maintain an open source project so any small contribution is greatly appreciated. NextSeo works by including it on pages where you would like SEO attributes to be added. Once included on the page you pass it a configuration object with the page's SEO properties. This can be dynamically generated at a page level or in some cases your API may return an SEO object. Then you need to import NextSeo and add the desired properties. This will render out the tags in the <head> for SEO. At a bare minimum, you should add a title and description. But NextSeo gives you many more options that you can add.

    No Coin

    No Coin

    No Coin is a tiny browser extension aiming to block coin miners

    No coin is a tiny browser extension aiming to block coin miners such as Coinhive. Even though I think using coin mining in browser to monetize content is a great idea, abusing it is not. Some websites are running it during the entire browsing session which results in high consumption of your computer's resources. I do believe that using it occasionally such as for the proof of work of a captcha is OK. But for an entire browsing session, the user should have the choice to opt-in which is the aim of this extension. The idea was to keep it separate from adblocking. Coin mining in the browser is a different issue. Where ads are tracking you and visually interfering with your browsing experience, coin mining, if abused, is eating your computer resources resulting in slow downs (from high CPU usage) and excessive power consumption. You might be OK with that and not with ads, or vice versa. Or you might just want to keep ads blocked entirely and just enable the coin mining script.

    Notifier for GitHub

    Notifier for GitHub

    Get notified about new GitHub notifications

    Checks for new GitHub notifications every minute and shows the number of notifications you have and shows desktop notifications as well. Displays your GitHub notifications unread count. It checks the GitHub Notifications API every minute. Supports GitHub Enterprise and an option to only show the unread count for issues you're participating in. Make sure to add a token to the Options page. Both requested permissions are optional, so you can just decline if you don't want them. The first time you click on the extension icon, it will ask you for access to browser tabs. We need this to know if there is already an opened GitHub notifications page and switch to it if so. If you want to receive desktop notifications, you can enable them on the extension options page. You will then be asked for the notification's permission.
