    1. For example, if error messages in two narrowly defined classes behave in the same way, the classes can be easily combined. But if some messages in a broad class behave differently, every object in the class must be examined before the class can be split. This illustrates the principle that "splits can be lumped more easily than lumps can be split".
    1. An example candidate for caching might be a nightly billing task which aggregates billing data for the past month. That kind of task is likely not expecting last minute updates while it runs. It assumes that the state of the world remains constant while processing.
    1. including Oracle (since 1984 [4]), Postgres(since 1985 [41]), and MySQL’s InnoDB engine (since 2001). Butwhile there are plenty of contemporaries to these older systemsthat use a single-version scheme (e.g., IBM DB2, Sybase), almostevery new transactional DBMS eschews this approach in favor ofMVCC [37]. This includes both commercial (e.g., Microsoft Heka-ton [16], SAP HANA [40], MemSQL [1], NuoDB [3]) and academic(e.g., HYRISE [21], HyPer [36]) systems

    1. of, relating to, or being a grammatical case or form expressing means or agency

      I really need an example of this!

      It seems unusual that they specifically mention "a grammatical case or form". I've never seen a definition before that is anything like this one.

      How is this different from definition 1?

    1. sadness.js will not load, however, as document.write() produces script elements which are "parser-inserted".
  3. developer.chrome.com developer.chrome.com
    1. If a user clicks on that button, the onclick script will not execute. This is because the script did not immediately execute and code not interpreted until the click event occurs is not considered part of the content script, so the CSP of the page (not of the extension) restricts its behavior. And since that CSP does not specify unsafe-inline, the inline event handler is blocked.
    1. This change was made because GitLab License Management is now renamed to GitLab License Compliance. After review with users and analysts, we determined that this new name better indicates what the feature is for, aligns with existing market terminology, and reduces confusion with GitLab subscription licensing features.
    1. $10 donation = $9.41 deposited into your bank account the next business day $100 donation = $96.80 deposited into your bank account the next business day
    1. In algebra, for some set S together with an operation ⋆ {\displaystyle \star } to form a group, it is necessary that ⋆ {\displaystyle \star } be associative.

      Seems like a simpler example (of individually necessary and jointly sufficient) that is easier to follow could be found.

    2. that a number x {\displaystyle x} is rational (S) is sufficient but not necessary to x {\displaystyle x} being a real number (N) (since there are real numbers that are not rational)
    3. being a male is a necessary condition for being a brother, but it is not sufficient—while being a male sibling is a necessary and sufficient condition for being a brother
    4. in order for human beings to live, it is necessary that they have air
    1. This does not have to be an additional form. In practice, you can simply add several checkboxes informing the user of each additional purpose and allowing them to give consent specific to those cases.

      See the images above, which are a good example of how to do it and how not to do it.

    1. By itself the name John Smith may not always be personal data because there are many individuals with that name. However, where the name is combined with other information (such as an address, a place of work, or a telephone number) this will usually be sufficient to clearly identify one individual.
    2. Simply because you do not know the name of an individual does not mean you cannot identify that individual. Many of us do not know the names of all our neighbours, but we are still able to identify them.
    1. If you’re selling products and keep record of users’ choices for marketing purposes, dividing them into meaningful categories, such as by age, gender, geographical origin etc., you’re profiling them.

    1. In informal contexts, mathematicians often use the word modulo (or simply "mod") for similar purposes, as in "modulo isomorphism".
    1. In December 2006, 34,000 actual user names and passwords were stolen in a MySpace phishing attack. The idea of the attack was to create a profile page named "login_home_index_html", so the URL looked very convincing. Specially-crafted HTML and CSS was used to hide the genuine MySpace content from the page and instead display its own login form.
    1. If you don't—or can't—lock your users in, the best way to compete is to innovate at a breakneck pace. Let's use Google Search as an example. It's a product that cannot lock users in: users don't have to install software to use it; they don't have to upload data to use it; they don't have to sign two-year contracts; and if they decide to try another search engine, they merely type it into their browser's location bar, and they're off and running.
    1. A simple, complete Chrome extension which injects a content script to click the button with id="product-addtocart-button" when you click on a browser_action button would be
    1. The handler can be a method or a Proc object passed to the :with option. You can also use a block directly instead of an explicit Proc object.

      Example of: letting you either pass a proc (as a keyword arg in this case) or as a block.

    1. if 𝑛nn does not divide 𝑚mm evenly, then the answer is the greatest common divisor of 𝑛nn and the remainder of 𝑚mm divided by 𝑛nn.

      m = 20, n = 10 20 / 10 = 2 CASE 1

      m = 100, n = 70 100 / 70 CASE 2 gcd(100, 100 % 70) =

      gcd(100, 30) gcd(100,30) CASE 2 gcd(100, 100 % 30) =

      gcd(100, 10) 100 / 10 = 10 CASE 1

      gcd(100, 70) = 10

    1. const setRefs = useRef(new Map()).current; const { children } = props; return ( <div> {React.Children.map(children, child => { return React.cloneElement(child, { // v not innerRef ref: node => { console.log('imHere'); return !node ? setRefs.delete(child.key) : setRefs.set(child.key, node)

      Illustrates the importance of having unique keys when iterating over children, since that allows them to be used as unique keys in a Map.

    2. useRef(new Map()).current
    1. Since an uncontrolled component keeps the source of truth in the DOM, it is sometimes easier to integrate React and non-React code when using uncontrolled components.

      A good example for when to use uncontrolled components

    1. Tests implementation details a bit (child component props received), but pretty good other than that.

      https://www.robinwieruch.de/react-testing-tutorial, for example, says that is reasonable to do:

      an integration test could verify that all necessary props are passed through from the tested component to a specific child component.

    1. Using expect { }.not_to raise_error(SpecificErrorClass) risks false positives, as literally any other error would cause the expectation to pass, including those raised by Ruby (e.g. NoMethodError, NameError, and ArgumentError)

      Actually, those would be false negatives: the absence of a test failure when it should be there.

      https://en.wikipedia.org/wiki/False_positives_and_false_negatives

    1. This is called a false positive. It means that we didn't get a test failure, but we should have

      No, this is a false negative. We didn't get a test failure (that is, there is a lack of the condition (test failure)), when the condition (test failure) should have been present.

    1. the branching timeline in Charles Renouvier’s 1876 Uchronia (Utopia in History): An Apocryphal Sketch of the Development of European Civilization Not as It Was But as It Might Have Been, depicting both the actual course of history and the various alternative paths that might have been if other actions had been taken.

    1. type FindByTag<Union, Tag> = Union extends { tag: Tag } ? Union : never; function cast<A extends Foo["tag"]>(foo: Foo, expectedTag: A): FindByTag<Foo, A> { if (foo.tag !== expectedTag) throw Error(`expected tag ${expectedTag} but was ${foo.tag}`) return foo as FindByTag<Foo, A>; }

    1. This is a ”stale closure”. I won’t get into closures, but just know that because of the implementation of React/hooks, the count variable is always going to be 0 in our interval function. It’s an old reference.
