One thing that matters is if code uses browser-specific (example: Dom) or server-specific (example: filesystem) features.

browser: points to browser-specific untranspiled code

This is a browser execution environment. It may provide additional built in objects exposed in the global namespace. It is a specialized execution environment which provides builtin capabilities beyond the base javascript language spec.

Using the browser field in package.json allows a module author to clearly articulate which files are innapropriate for client use and provide alternatives.

It allows the module code (and subsequently dependants on the module) to not use preprocessor hacks, source code changes, or runtime detection hacks to identify which code is appropriate when creating a client bound package.

Consider that the client environment as the special case as it exposes objects into the global space to provide certain features and limits others.

The browser field is where the module author can hint to the bundler which elements (other modules or source files) need to be replaced when packaging.

When a javascript module is prepared for use on a client there are two major concerns: certain features are already provided by the client, and certain features are not available. Features provided by a client can include http requests, websockets, dom manipulation. Features not available would include tcp sockets, system disk IO.

You can simply prevent a module or file from being loaded into a bundle by specifying a value of false for any of the keys. This is useful if you know certain codepaths will not be executed client side but find it awkward to split up or change the code structure.

Second, uBlock Origin does not have a dedicated server, it can't "phone home" with your browsing data, there is only GitHub, and GitHub is completely unrelated to uBlock Origin.

This does not set the native input element to indeterminate due to inconsistent behavior across browsers. However, we set a data-indeterminate attribute on the input.

AdNauseam

"While we hope that Google will lift these unwarranted sanctions for AdNauseam, it highlights a much more serious problem for Chrome users," the AdNauseam team adds. "It is frightening to think that at any moment Google can quietly make your extensions and data disappear, without so much as a warning."

What Tools/Libraries Do You Use To Visualize Genomic Feature Data?

ASCIIGenome is a command-line genome browser running from terminal window

Artemis is a free genome browser and annotation tool that allows visualisation of sequence features, next generation data and the results of analyses within the context of the sequence, and also its six-frame translation

Genome Maps is a modern and high-performance web-based HTML5 genome browser

Plot a course through the genome Inspired by Google Maps, a suite of tools is allowing researchers to chart the complex conformations of chromosomes.

6.2 Extension IDs Each extension has an extension ID that follows the browserext:// protocol. For example browserext://MyExtension_c1wakc4j0nefm/options.html browserext://dfcijpibodeoenkablikbkiobbdnkfki/options.html The algorithms that generate these IDs are different for each browser. To access these resources, do not hardcode the ID generated by a particular browser. Instead, use the runtime.getURL() method to convert a relative file name or path to the absolute name or path, which includes the extension ID.

Back then there were two major browsers competing for the soul of the web: Microsoft Internet Explorer and Netscape Navigator. They were incompatible by design. One browser would invent a new HTML element or attribute.

Browser software may ignore this tag.

You must quit IGV and restart for this preference to take effect. The genome should appear in the drop-down list.

Client<->Server API - defines how Matrix compatible clients communicate with Matrix homeservers. Server<->Server API - defines how Matrix homeservers exchange messages and synchronise history with each other.

What about extensions for other browsers? We’re working on that. The next supported browser is likely to be Firefox.

does anyone not use Chrome?

When we first set out to identify malicious extensionsour expectation was to find banking trojans and pass-word stealers that duplicated the strategies pioneered byZeus and SpyEye. In practice, the abusive extensionecosystem is drastically different from malicious bina-ries. Monetization hinges on direct or indirect relation-ships with syndicated search partners and ad injection af-filiate programs, some of which earn millions of dollarsfrom infected users [37]. Miscreants derive wealth fromtrafficanduser targetingrather than the computing re-sources or privileged access mediated via the browser. Itmay simply be that the authors of malicious binaries havelittle incentive (or external pressure) to change, leavingextensions to a distinct set of actors. This uncertainty isa strong motivation for exploring the extension ecosys-tem further.
