This specification reserves the use of one URI as a problem type: The "about:blank" URI [RFC6694], when used as a problem type, indicates that the problem has no additional semantics beyond that of the HTTP status code. When "about:blank" is used, the title SHOULD be the same as the recommended HTTP status phrase for that code (e.g., "Not Found" for 404, and so on), although it MAY be localized to suit client preferences (expressed with the Accept-Language request header). Please note that according to how the "type" member is defined (Section 3.1), the "about:blank" URI is the default value for that member. Consequently, any problem details object not carrying an explicit "type" member implicitly uses this URI.

Svelte is different in that by default most of your code is only going to run once; a console.log('foo') line in a component will only run when that component is first rendered.

The input is required and initially empty, so on page load the input is :invalid and border is red. :( :(The input is :invalid until you type a legit email address, so it is red when typing. :( :(Ok, so the :invalid pseudo selector is kind of useless. Ideally we would not show an error up front or the whole time they are typing, just when they submit something unacceptable.

Because the Berne Convention in most countries by default grants copyright holders monopolistic control over their creations, copyright content must be explicitly declared free, usually by the referencing or inclusion of licensing statements from within the work.

To stop emitting the warnings, just add RUBYOPT=-W:no-deprecated.

However, a ActiveRecord::Rollback within the nested transaction will be caught by the block of the nested transaction, but will be ignored by the outer transaction, and not cause a roll back! To avoid this unexpected behaviour, you have to explicitly tell rails for each transaction to indeed use proper nesting: CopyActiveRecord::Base.transaction(joinable: false, requires_new: true) do # inner code end This is a safer default for working with custom transactions.
