    1. keepschoolopeninordertoprovidethekindofeducationthatweunderstandisbest.

      Is "the kind of education that we understand is best" worth the loss of lives of teachers? Students? How many? What's the tolerance threshold for this?

      Are worksheets with no classroom content while quarantining a better kind of education than setting up a camera to allow students to remotely participate in classroom activities?

    1. Also note thet width: 100% is relative to it's first parent with a layout. So if you have an element with width:100% inside another element that has a specific width, the child element will only take up the total width of that parent.

    1. Giving peers permission to engage in dialogue about race and holding a lofty expectation that they will stay engaged in these conversations throughout the semester or year is the first of the four agreements for courageous conversation. While initially, some participants may be eager to enter into these conversations, our experience indicates that the more personal and thus risky these topics get, the more difficult it is for participants to stay committed and engaged." Singleton and Hays

    1. When responding to DiskPressure node condition, the Kubelet first evicts BestEffort pods followed by Burstable pods. Only when there are no BestEffort or Burstable pods left are Guaranteed pods evicted.
    2. Both Guaranteed and Burstable pods whose resource usage is lower than the requested amount are never evicted because of the resource usage of another pod. They might, however, be evicted if system daemons start using more resources than reserved. In this case, Guaranteed and Burstable pods with the lowest priority are evicted first.

      If I want to make it as unlikely as possible that a pod is evicted, I have to make sure that the request is higher or equal than the highest possible use of resources within that pod.

    3. order of eviction depends on the priority assigned to each pod and the amount of resources being consumed above request
    1. -- The array on the right side is not considered contained within the -- array on the left, even though a similar array is nested within it: SELECT '[1, 2, [1, 3]]'::jsonb @> '[1, 3]'::jsonb; -- yields false -- But with a layer of nesting, it is contained: SELECT '[1, 2, [1, 3]]'::jsonb @> '[[1, 3]]'::jsonb;
    1. We need to be really careful about what's 'same origin' because the server has no idea what host/path the various cookies are associated with. It just has a list of cookies that the browser had determined to be relevant for this SSR'd page, and not for any other subrequests.

    1. As the token is unique and unpredictable, it also enforces proper sequence of events (e.g. screen 1, then 2, then 3) which raises usability problem (e.g. user opens multiple tabs). It can be relaxed by using per session CSRF token instead of per request CSRF token.
    1. The difference is that this happens in the email client, not at the subscription step. Why is this a big deal? Because, even though they just subscribed to your email, there’s a chance your email won’t get a thumbs up.
    1. The element that we are going to apply the shape to with the shape-outside property to has to be floated. It also has to have a defined width and height. That's really important to know!

    1. It has two very different meanings, that you would have to distinguish by context. One meaning is just expressing that we have limitations. If you don't know something, that's just tough, you don't know it and you have to live with that. You don't have information if you don't have that information. The other meaning is that not only are there gaps in our knowledge, but often we don't even know what the gaps in our knowledge are. I don't know how to speak Finnish. That's a gap in my knowledge that I know about. I know that I don't know how to speak Finnish. But there are gaps in my knowledge that I'm not even aware of. That's where you can say "You don't know what you don't know" meaning that you don't even know what knowledge you are missing.

      I had this thought too.

    1. Today, many users rely upon graphical user interfaces and menu-driven interactions. However, some programming and maintenance tasks may not have a graphical user interface and may still use a command line.
    1. Notice the use of Enter key after backslash in the sed command.
    2. Although echo "$@" prints the arguments with spaces in between, that's due to echo: it prints its arguments with spaces as separators.

      due to echo adding the spaces, not due to the spaces already being present

      Tag: not so much:

      whose responsibility is it? but more: what handles this / where does it come from? (how exactly should I word it?)

    1. A modified timestamp signifies the last time the contents of a file were modified. A program or process either edited or manipulated the file. “Modified” means something inside the file was amended or deleted, or new data was added. Changed timestamps aren’t referring to changes made to the contents of a file. Rather, it’s the time at which the metadata related to the file was changed. File permission changes, for example, will update the changed timestamp.

      They shouldn't use synonyms for this (modified = changed).

      It would be clearer if the word that differed between the terms indicated what changed:

      • "content modified" time (cctime)?
      • "meta modified" time (cmtime)?
    1. that can be played by up to 10 local players - turnwise.

      Description just said:

      Party mode brings Versus mode and Marathon mode where up to 10 players can play together and compete locally.

      Didn't mention whether it was at same time or in sequence. Hmm. Which is it? Video shows at least 2 can play at same time, so...

    1. CSS-generated content is not included in the DOM. Because of this, it will not be represented in the accessibility tree and certain assistive technology/browser combinations will not announce it. If the content conveys information that is critical to understanding the page's purpose, it is better to include it in the main document.
    1. Academy Games has always prided itself in the quality of its rules. Most of our rules are taught in stages, allowing you to start playing as soon as possible without needing to read everything. We are very careful about the order we teach rules and rely heavily on graphics and pictures to facilitate understanding. We also include a large number of detailed picture examples, often with 3D renders, that help you understand the context of the rules.

    1. Fiche 3.6 -  Travailler la communication interne au sein de l’établissement

      C'est le seul point ou l'on voit apparaitre à la marge les parents d'élèves. et aucunement des RPE et de leurs associations.

      voici les points cités comme à vérifier • Faciliter l’appropriation de l’information diffusée pour les personnels et les usagers : taux de sollicitation pour demander des informations au sujet de questions ayant déjà fait l’objet d’une communication, taux de réponses aux sollicitations de l’établissement avant d’éventuelles relances…

      • Indicateur de visibilité : nombre de connexion à l’ENT de l’établissement, nombre de contributeurs internes au site et autres outils de communication…
      
      • Indicateurs relatifs aux familles : taux de participation aux élections du conseil d’administration, aux réunions parents/professeurs, aux différentes actions, groupes de travail ou manifestations auxquelles elles sont invitées.
      
      • Indicateurs d’enquêtes de satisfaction (construites en interne).
      
      • Identification claire par l’ensemble des membres de la communauté scolaire des « référents communication » de l’établissement.
      
    1. The distinction in computer programming between classes and objects is related, though in this context, "class" sometimes refers to a set of objects (with class-level attribute or operations) rather than a description of an object in the set, as "type" would.
    1. Dictionary writers list polysemes under the same entry; homonyms are defined separately.

      This describes how you can tell which one it is by looking at the dictionary entry.

    2. Polysemy is thus distinct from homonymy—or homophony—which is an accidental similarity between two words (such as bear the animal, and the verb to bear); while homonymy is often a mere linguistic coincidence, polysemy is not.
    1. Third configurable block to run.

      I like how they identify in the description which order things run in: 1st, 2nd, 3rd, and last.

      Though, it would be more readable to have a list of them, in chronological order, rather than having them listed in alphabetical order.

    2. Last configurable block to run. Called after frameworks initialize.
    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. The :empty selector refers only to child nodes, not input values. [value=""] does work; but only for the initial state. This is because a node's value attribute (that CSS sees), is not the same as the node's value property (Changed by the user or DOM javascript, and submitted as form data).
    2. Generally, CSS selectors refer to markup or, in some cases, to element properties as set with scripting (client-side JavaScript), rather than user actions. For example, :empty matches element with empty content in markup; all input elements are unavoidably empty in this sense. The selector [value=""] tests whether the element has the value attribute in markup and has the empty string as its value. And :checked and :indeterminate are similar things. They are not affected by actual user input.
    3. The selector [value=""] tests whether the element has the value attribute in markup and has the empty string as its value.

    1. Using Track() with a new track semantic only makes sense when using the [:magnetic_to option] on other tasks.
    1. For example, what if your site has a customer interface and an “admin” interface? If the two have totally different designs and features, then it might be considerable overhead to ship the entirety of the admin interface to every customer on the regular site.
    1. If any of the inputs are invalid, #execute won't be run.

      It does staged/pipelined execution/validation.

      If any of these stages has any errors, then no other stages will be executed:

      1. validations on the inputs of the interaction itself
      2. run execute, which may:
      3. may use compose, which will (IIUC) abort the entire execute/run early if any of them fail, even if there are later composed interactions still to be run
      4. may try to save inputs into models, which themselves may have validation errors, which (assuming we use errors.merge), will show up on the interaction.errors (but won't abort the rest of the execute)
    2. There are times where it is useful to know whether a value was passed to run or the result of a filter default. In particular, it is useful when nil is an acceptable value.

      Yes! An illustration in ruby:

      main > h = {key_with_nil_value: nil}
      => {:key_with_nil_value=>nil}
      
      main > h[:key_with_nil_value]
      => nil
      
      main > h[:missing_key]  # this would be undefined in JavaScript (a useful distinction) rather than null, but in Ruby it's indistinguishable from the case where a nil value was actually explicitly _supplied_ by the caller/user
      => nil
      
      # so we have to check for "missingness" ("undefinedness"?) differently in Ruby
      
      main > h.key?(:key_with_nil_value)
      => true
      
      main > h.key?(:missing_key)
      => false
      

      This is one unfortunate side effect of Ruby having only nil and no built-in way to distinguish between null and undefined like in JavaScript.

    3. When you run this interaction, two things will happen. First ActiveInteraction will type check your inputs. Then ActiveModel will validate them. If both of those are happy, it will be executed.

      Failed type checks generate run-time errors. So it's up to the develop to fix these, permanently, since the user can't (99% of time) do anything to fix these.

      Failed validations add errors to interaction.errors object. These are for the user to fix.

    1. The problem is that you what you want is actually not de-structuring at all. You’re trying to go from 'arg1', { hash2: 'bar', hash3: 'baz' }, { hash1: 'foo' } (remember that 'arg1', foo: 'bar' is just shorthand for 'arg1', { foo: 'bar' }) to 'arg1', { hash1: 'foo', hash2: 'bar', hash3: 'baz' } which is, by definition, merging (note how the surrounding structure—the hash—is still there). Whereas de-structuring goes from 'arg1', [1, 2, 3] to 'arg1', 1, 2, 3
    1. DSLs can be problematic for the user since the user has to manage state (e.g. am I supposed to call valid? first or update_attributes?). This is exactly why the #validate is the only method to change state in Reform.
    2. The reason Reform does updating attributes and validation in the same step is because I wanna reduce public methods. This is to save users from having to remember state.

      I see what he means, but what would you call this (tag)? "have to remember state"? maybe "have to remember" is close enough

      Or maybe order is important / do things in the right order is all we need to describe the problem/need.

    1. cultural capital

      Introduced by Pierre Bourdieu in the 1970s, the concept has been utilized across a wide spectrum of contemporary sociological research. Cultural capital refers to ‘knowledge’ or ‘skills’ in the broadest sense. Thus, on the production side, cultural capital consists of knowledge about comportment (e.g., what are considered to be the right kinds of professional dress and attitude) and knowledge associated with educational achievement (e.g., rhetorical ability). On the consumption side, cultural capital consists of capacities for discernment or ‘taste’, e.g., the ability to appreciate fine art or fine wine—here, in other words, cultural capital refers to ‘social status acquired through the ability to make cultural distinctions,’ to the ability to recognize and discriminate between the often-subtle categories and signifiers of a highly articulated cultural code. I'm quoting here from (and also heavily paraphrasing) Scott Lash, ‘Pierre Bourdieu: Cultural Economy and Social Change’, in this reader.

    1. Blocks Don’t Need 100% Width When we understand the difference between block-level elements and inline elements, we’ll know that a block element (such as a <div>, <p>, or <ul>, to name a few) will, by default expand to fit the width of its containing, or parent, element (minus any margins it has or padding its parent has).
    1. Why is CORS important? Currently, client-side scripts (e.g., JavaScript) are prevented from accessing much of the Web of Linked Data due to "same origin" restrictions implemented in all major Web browsers. While enabling such access is important for all data, it is especially important for Linked Open Data and related services; without this, our data simply is not open to all clients. If you have public data which doesn't use require cookie or session based authentication to see, then please consider opening it up for universal JavaScript/browser access. For CORS access to anything other than simple, non auth protected resources
    1. A common and simplistic type of statistical testing is a z-test, which tests the statistical significance of a sample mean to the hypothesized population mean but requires that the standard deviation of the population be known, which is often not possible. The t-test is a more realistic type of test in that it requires only the standard deviation of the sample as opposed to the population's standard deviation.

      To perform the actual test, we do a z-test or a t-test. For t-tests you need to know the population standard deviation, which is often not possible. T-test only requires standard deviation of a sample, which is more realistic.

    2. if the P-test fails to reject the null hypothesis then the test is deemed to be inconclusive and is in no way meant to be an affirmation of the null hypothesis.

      Why?

    1. This explains how much X varies from its mean when Y varies from its own mean.

      Covariance: How much does X vary from its mean when Y varies from its mean.

      • Notice that x_i and y_i can be +ve or -ve, therefore their product will also be +ve(x_i deviates in +ve direction away from mean and y_i also deviates in +ve direction away from mean or they both deviate negatively away from the mean) or -ve(x_i deviates +vely and y_i deviates -vely from the mean and viceversa). We then sum all of the products up. A +ve covariance will indicate that on average the values had a +ve linear relationship, -ve indicates a -ve linear relationship, and 0 indicates that all products cancelled out which means they were equally +ve and -ve relationships, and therefore no overall relatonship.
    1. People really don't stress enough the importance of enjoying what you're programming. It aids creativity, makes you a better teammate, and makes it significantly easier to enter a state of flow. It should be considered an important factor in choosing a web development framework (or lack thereof). Kudos!

    1. delete will only work on properties whose descriptor marks them as configurable.
    2. The delete operator does not directly free memory, and it differs from simply assigning the value of null or undefined to a property, in that the property itself is removed from the object.
    1. this in particular comes from the addressee

      I think the ruling's main point/distinction here is that while submitting a form might be getting consent from the addressee (the person submitting form might be the addressee, if they own the e-mail address they entered), but we can't know that for sure until they confirm by clicking a link in the e-mail.

      Only then do we know for sure that the actor submitting the form was the addressee and that the consent ostensibly received via the form was in fact from the addressee. But it could otherwise be the case that they entered someone else's address, and you can't give consent on behalf of someone else!

    1. This module should not be used in other npm modules since it modifies the default require behavior! It is designed to be used for development of final projects i.e. web-sites, applications etc.
    1. The resolving process is basically simple and distinguishes between three variants: absolute path: require("/home/me/file") relative path: require("../src/file") or require("./file") module path: require("module/lib/file")

      Very important distinction

    1. We expect a certain pattern when validate devtool name, pay attention and dont mix up the sequence of devtool string. The pattern is: [inline-|hidden-|eval-][nosources-][cheap-[module-]]source-map.
    1. Using as * adds a module to the root namespace, so no prefix is required, but those members are still locally scoped to the current document.

      distinction:

      • root namespace (so no prefix is required), but
      • locally scoped (to the current document)
