    1. Some would argue that the phrase ''survival of the fittest'' is tautological, in that the fittest are defined as those that survive to reproduce.

    1. Using a flag to disable prettier for a line, the next line or until I activate it again (ESLint like syntax). // prettier-disable border: { sep: "║", topLeft: "╔", topMid: "╦", top: "═", topRight: "╗", midLeft: "╠", midMid: "╬", mid: "═", midRight: "╣", botLeft: "╚", botMid: "╩", bot: "═", botRight: "╝" }, // prettier-enable
    1. Here is one of the most confusing cases: def foo(x, **kwargs) p [x, kwargs] end def bar(x=1, **kwargs) p [x, kwargs] end foo({}) #=> [{}, {}] bar({}) #=> [1, {}] bar({}, **{}) #=> expected: [{}, {}], actual: [1, {}]
    2. If you extend a method to accept keyword arguments, the method may have incompatibility as follows: # If a method accepts rest argument and no `**nil` def foo(*args) p args end # Passing keywords are converted to a Hash object (even in Ruby 3.0) foo(k: 1) #=> [{:k=>1}] # If the method is extended to accept a keyword def foo(*args, mode: false) p args end # The existing call may break foo(k: 1) #=> ArgumentError: unknown keyword k

    1. SELECT base.nr, multiples.multiple FROM (SELECT generate_series(1,10) AS nr) base, LATERAL ( SELECT multiples.multiple FROM ( SELECT generate_series(1,10) AS b_nr, base.nr * 2 AS multiple ) multiples WHERE multiples.b_nr = base.nr ) multiples;
    1. Critical to the acceptance of the position of the script subtag was the inclusion of information in the registry to make clear the need to avoid script subtags except where they add useful distinguishing information. Thus, the registry entry for the language subtag "en" (English) has a field called "Suppress-Script" indicating that the script subtag "Latn" should be avoided with that language, since virtually all English documents use the Latin script.
      • not worth saying
      • not necessary to say/write
      • useless information

      Suppress-Script

    2. Language Range ... matches ... does not match de de, de-CH, de-AT, de-DE, de-1901, de-AT-1901 en, fr-CH
    1. SELECT * FROM ( -- build virtual table of all hours between -- a date range SELECT start_ts, start_ts + interval '1 hour' AS end_ts FROM generate_series( '2017-03-01'::date, '2017-03-03'::timestamp - interval '1 hour', interval '1 hour' ) AS t(start_ts) ) AS cal LEFT JOIN ( -- build virtual table of uptimes SELECT * FROM ( VALUES ('2017-03-01 01:15:00-06'::timestamp, '2017-03-01 02:15:00-06'::timestamp), ('2017-03-01 08:00:00-06', '2017-03-01 20:00:00-06'), ('2017-03-02 19:00:00-06', null) ) AS t(start_ts, end_ts) ) AS uptime ON cal.end_ts > uptime.start_ts AND cal.start_ts <= coalesce(uptime.end_ts, current_timestamp)

    1. Use cases: Volumes are most useful when you need more storage space but don’t need the additional processing power or memory that a larger Droplet would provide, like: As the document root or media upload directory for a web server To house database files for a database server As a target location for backups As expanded storage for personal file hosting platforms like ownCloud As components for building more advanced storage solutions, like RAID arrays
    1. An escalator is a great example of progressive enhancement and graceful degradation in real life. The late comedian Mitch Hedberg joked, “An escalator can never break: it can only become stairs. You should never see an Escalator Temporarily Out Of Order sign, just Escalator Temporarily Stairs. Sorry for the convenience.” Regardless of its environment, an escalator maintains its functionality.
  5. Apr 2021
    1. the double bind faced by every politician: responding to scurrilous charges only gives them unwarranted publicity; not responding to such charges is often interpreted as an admission of guilt
    1. Adding another Steven Wright gem: "24 hour banking? I don't have time for that."
    2. Comedian Henny Youngman was famous for one-liners delivered in a deadpan manner. Much of his humor was both wry and dry. For example, his most famous line: Take my wife ... please. If you never saw the delivery, "Take my wife" was said as if he was using his wife as an example to set up a situation, as in "Take my wife [for example]." After a brief pause, the "please" turned it into a request.
    3. I'm sorry I hurt your feelings when I called you stupid. I really thought you already knew.
    1. British HumorDry humor is particularly associated with British humor. Fawlty Towers, a British television comedy that aired from 1975 to 1979 is considered an unusually good example of dry humor. The series is set in a family run seaside hotel operated by a cynical and snobbish man, played by John Cleese, who finds himself in constant conflict with hotel guests. No matter how outlandishly silly each episode becomes, there is never any sense that the characters are trying to be funny.
    1. If you want to pipe it into something interactive, like less -R, where terminal input goes to less -R, then you need some extra trickery. For example, I wanted a colourful version of git status | less. You need to pass -R to less in order that it respect the colours, and you need to use script to get git status to output colour. But we don't want script to keep ownership of the keyboard, we want this to go to less. So I use this now and it works well: 0<&- script -qfc "git status" /dev/null | less -R . Those first few characters close stdin for this one commmand.

      Just git status | less -R worked for me without any additional trickery, but I see now that's because I told it to "always" use color in my .gitconfig:

      .[color]
        ui = always
        status = always
      

      I tried disabling that and then trying the

      0<&- script -qfc "git status" /dev/null | less -R
      

      trick, but it didn't work for me. It didn't show any output and I couldn't exit out with Ctrl-C or anything I tried. Had to force kill from another terminal.

      But it's a good example of the related but different problems:

      1. forcing less to respect colors (easy)
      2. force/trick git status to think it has a terminal
      3. force/trick it so you can control keyboard with less
    1. Incredible Mandy is a great example of design by subtraction, focusing on puzzle-solving and atmosphere and eschewing mechanics which do not contribute to the developer’s singular vision.
    1. An example of this would be a button that looks clickable but isn’t, underlined text that doesn’t contain a link, or a TV remote that turns on your lights but not the TV. False affordances are often present by mistake or occur due to lack of effective design techniques.
  6. Mar 2021
    1. A business with a low barrier to entry would be those people in poor countries who “wash” your windscreen at traffic lights. A bucket, a cloth, some water and you are in business. A business with a high barrier to entry might be airlines: planes are expensive, staff with the right skills hard to find, the necessary permits to fly hard to obtain.
    1. The sentence "they drive the same car" is ambiguous. Do they drive the same type of car (the same model) or the same instance of a car type (a single vehicle)?
    1. For instance, in basketball there are many words that are specific to the sport. Free throw, court, half court, three pointer, and point guard are all terms that are specific to the sport of basketball. These words make very little sense when used outside of the semantic domain of basketball.

      But this example seems so different than the first example they gave, "rain", which seems more like a semantic field — a group of very related or nearly synonymous words.

    1. Every woman talked to a student. This has two interpretations. Under one reading, every woman talked to the same student (the class president, for example), and here the noun phrase a student is specific. Under the second reading, various students were talked to. In this case, a student is non-specific.
    1. endpoint Diagram::Operation::Create do |ctx, **| redirect_to diagram_path(ctx[:diagram].id) end.Or do |ctx, **| render :form end
    1. Suppose an administrator creates a forum using open source forum software, and then heavily modifies it by adding new features and options. This process requires extensive modifications to existing code and deviation from the original functionality of that software.
    2. cannot be run on any modern day computer or computer simulator, as it was developed during the days when LISP and PLANNER were still in development stage, and thus uses non-standard macros and software libraries which do not exist anymore
    1. Before a bug can be fixed, it has to be understood and reproduced. For every issue, a maintainer gets, they have to decipher what was supposed to happen and then spend minutes or hours piecing together their reproduction. Usually, they can’t get it right, so they have to ask for clarification. This back-and-forth process takes lots of energy and wastes everyone’s time. Instead, it’s better to provide an example app from the beginning. At the end of the day, would you rather maintainers spend their time making example apps or fixing issues?
    1. Another example: a list (<ul> or <ol>) should generally be used to group similar items (<li>). You could use a div for the group and a <span> for each item, and style each span to be on a separate line with a bullet point, and it might look the way you want. But "this is a list" conveys more information.
    2. The classic example is that if something is a table, it should contain rows and columns of data. To use that for layout is semantically incorrect - you're saying "this is a table" when it's not.
    1. Website: <input type="url" name="website" required pattern="https?://.+"> Now our input box will only accept text starting with http:// or https:// and at least one additional character
    1. Why don’t we put the “create user” task onto the failure track, and in case of successfully persisting the new user, we deviate back to the happy path?
    2. To implement such an activity, we only need to rewire the second step’s failure output to a new terminus.
    3. Visualized, our new composed structure would look as follows.
    4. Suppose that the validate task was getting quite complex and bloated. When writing “normal” Ruby, you’d break up one method into several. In Trailblazer, that’s when you introduce a new, smaller activity.
  7. Feb 2021
    1. step :policy, before: :create_model
    2. the validate task gets removed, assuming the Admin won’t need a validation
    3. step Subprocess(Memo::Validate), Output(:invalid_params) => Track(:failure)
    4. step :charge_creditcard, Output(:failure) => End(:declined)
    5. step :charge_creditcard, Output(:failure) => End(:success) end This reconnects both outputs to the same end, always ending in a - desirable, yet unrealistic - successful state.
    6. step :find_provider, Output(UsePaypal, :paypal) => Track(:paypal)
    1. While you could program this little piece of logic and flow yourself using a bunch of Ruby methods along with a considerable amount of ifs and elses, and maybe elsif, if you’re feeling fancy, a Trailblazer activity provides you a simple API for creating such flow without having to write and maintain any control code. It is an abstraction.
    1. {a: 1, b: 2, c: 3, d: 4} => {a:, b:, **rest} # a == 1, b == 2, rest == {:c=>3, :d=>4}

      equivalent in javascript:

      {a, b, ...rest} = {a: 1, b: 2, c: 3, d: 4}
      

      Not a bad replacement for that! I still find javascript's syntax a little more easily readable and natural, but given that we can't use the same syntax (probably because it would be incompatible with existing syntax rules that we can't break for compatibility reasons, unfortunately), this is a pretty good compromise/solution that they've come up with.

    1. def edit account = find_account! @account = UpdateAccount.new( account: account, first_name: account.first_name, last_name: account.last_name) end
    2. > RecordInteraction.run!(encoding: 'ascii') => #<Encoding:US-ASCII>

      Makes use of the fact that you can do:

      main > Encoding.find('ascii')
      => #<Encoding:US-ASCII>
      

      and that

      If the value does not match, it will call find on the class of the record.

    1. describe '.validate(context, filters, inputs)' do let(:inputs) { {} } let(:filter) { ActiveInteraction::Filter.new(:name, {}) } let(:interaction) do
    1. In a rule-based system, a metarule is a rule governing the application of other rules.
    1. The word home, for instance, has a denotation of “the place (such as a house or apartment) where a person lives,” but it may additionally have many connotations (such as “warmth,” “security,” or “childhood”) for some people.
    1. Say you have software to keep track of your grocery list. In the 80's, this software would work against a command line and some flat files on floppy disk. Then you got a UI. Then you maybe put the list in the database. Later on it maybe moved to the cloud or mobile phones or facebook integration. If you designed your code specifically around the implementation (floppy disks and command lines) you would be ill-prepared for changes. If you designed your code around the interface (manipulating a grocery list) then the implementation is free to change.
    2. It's more like providing an Employee object rather than the set of linked tables you use to store an Employee record. Or providing an interface to iterate through songs, and not caring if those songs are shuffled, or on a CD, or streaming from the internet. They're just a sequence of songs.
    1. class ConferencesController def create conference = Conference.new @conference_form = ConferenceForm.new(conference) @conference_form.submit(conference_params) if @conference_form.save redirect_to @conference_form, notice: "Conference: #{@conference_form.name} was successfully created." } else render :new end end end
    1. class UsersController < ApplicationController def create success = -> (response, time) { redirect_to root_path, notice: "#{response} - at: #{time}" } failure = -> { render :new } Workflow::CreateUser.call(params[:name], success: success, failure: failure) end end
    1. The first problem is that if you ever remove an item, there will be a big black block in the layout. Maybe that’s OK, but more likely it isn’t. The second problem is that grid containers do not, by default, shrink-wrap their items. Instead, they fill out the parent element, as block boxes do. Both of these problems are illustrated in Figure 6.
    2. #ttt > * { border: 1px solid black; border-width: 0 1px 1px 0; display: flex; /* flex styling to center content in divs */ align-items: center; justify-content: center; } #ttt > *:nth-of-type(3n) { border-right-width: 0; } #ttt > *:nth-of-type(n+7) { border-bottom-width: 0; }
    1. .box1 { grid-column-start: 1; grid-column-end: 4; grid-row-start: 1; grid-row-end: 3; } .box2 { grid-column-start: 1; grid-row-start: 2; grid-row-end: 4; }

    1. config.action_mailer.register_preview_interceptor :css_inline_styler

      That's probably the same hook that https://github.com/fphilipe/premailer-rails ties into, for it says:

      Emails are only processed upon delivery, i.e. when calling #deliver on the email, or when previewing them in rails.

    1. I want to make some add-ons or wrappers on components e.g BigButton.svelte <script> import Button from './Button.svelte' </script> <Button fz="16" h="64" {...$$props}> <slot slot="prepend" name="prepend" /> <slot /> <slot slot="append" name="append" /> </Button>
    1. beforeUpdate(async () => { console.log('the component is about to update'); await tick(); console.log('the component just updated'); });
    1. You may want the tippy to appear at a different location from its trigger (event listeners) target. For example:
  9. Nov 2020
  10. Oct 2020
    1. Returns a Promise<?Object> that resolves with no value on success or resolves with an Object of submission errors on failure. The reason it resolves with errors is to leave rejection for when there is a server or communications error.
    1. Not all application state belongs inside your application's component hierarchy. Sometimes, you'll have values that need to be accessed by multiple unrelated components, or by a regular JavaScript module.
    1. const { getByRole } = render(html`<input bind:value=${text} />`)
    2. render(html`<${Button} on:click=${() => (clicked += 1)}>Click Me!<//>`)

      Compared to https://github.com/kenoxa/svelte-jsx#api, this alows on:click instead of on_click.

      So maybe this syntax allows for fewer workarounds overall?

    1. This would be like an executable proposal. I understand that it's beyond the original intent of having canonical patterns on the Svelte site, but it would facilitate the community to express their own patterns. Now that we have markdown preprocessors , the documentation itself can be an app.
    1. This seems crucial, for example for #if inside #each {#each boxes as box} {@const b = box?.a?.b} {#if b} <p>{b}</p> {/if} {/each}
    1. Data fetching, setting up a subscription, and manually changing the DOM in React components are all examples of side effects.

    1. The difference between default and named affects how other people can consume your bundle. If you use default, a CommonJS user could do this, for example:

      include the following content

    1. For example, you might want to use the browser’s knowledge of the user’s current time zone to group a collection of elements by date.

    1. But it's easy to imagine that the caption was incorrect for too long because those who know the language, know where the mistake is, and those who don't, think that it's the correct way to spell it.

      those who know the language, know where the mistake is, In other words, they can easily spot the mistake and no better than to repeat it themselves, but either are powerless or too lazy to actually fix it on SE.

      and those who don't, think that it's the correct way to spell it. So those who should no better are inadvertently perpetuating the mistake and teaching others that it is an acceptable/correct usage.

    1. Perhaps someone should give an example of when 'into' is ever correct. "Turn into bed" is definitely incorrect, unless one is morphing into the form of a bed. But what about "he fell into the hole", "she went into the house", or "Star Trek Into Darkness"?
    1. For example, the word dog describes both the species Canis familiaris and male individuals of Canis familiaris, so it is possible to say "That dog isn't a dog, it's a bitch" ("That hypernym Z isn't a hyponym Z, it's a hyponym Y").
  13. Jun 2020
    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.
  14. May 2020
    1. sadness.js will not load, however, as document.write() produces script elements which are "parser-inserted".
  15. 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. 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)
    2. 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
    3. 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.
