    1. Een chunk (letterlijk ‘brok’) is een verzameling elementen die sterke associaties met elkaar hebben. Samen vormen ze een betekenisvolle informatie-eenheid. Die chunks, groot of klein, gebruiken we in ons interne informatieverwerkings- en geheugensysteem. Ons brein houdt namelijk van logica en voorspelbare patronen. Het opdelen van informatie gebeurt automatisch en continu, maar kan ook bewust worden ingezet. Dat heet doel-georiënteerde chunking.Ons brein kan slechts een aantal zaken opslaan in het kortetermijngeheugen. Maar door veel gegevens te groeperen in kleinere brokjes informatie, kunnen we de limieten van ons geheugen uitdagen. En dus meer informatie verwerken en onthouden.

      Chapeau! Een Belgische website kaart dit aan in de context gezond leven.

    1. Gould, Jessica. “Teachers College, Columbia U. Dissolves Program behind Literacy Curriculum Used in NYC Public Schools.” Gothamist, September 8, 2023. https://gothamist.com/news/columbia-university-dissolves-program-behind-literacy-curriculum-used-in-nyc-public-schools.

      The Teachers College of Columbia University has shut down the Lucy Calkins Units of Study literacy program.

      Missing from the story is more emphasis on not only the social costs, which they touch on, but the tremendous financial (sunk) cost to the system by not only adopting it but enriching Calkins and the institution (in a position of trust) which benefitted from having sold it.

    1. Unlike many developed countries, the United States lacks a national curriculum or teacher-training standards. Local policies change constantly, as governors, school boards, mayors and superintendents flow in and out of jobs.

      Many developed countries have national curricula and specific teacher-training standards, but the United States does not. Instead decisions on curricular and standards are created and enforced at the state and local levels, often by politically elected figures including governors, mayors, superintendents, and school boards.

      This leaves early education in the United States open to a much greater sway of political influence. This can be seen in examples of Texas attempting to legislate the display the ten commandments in school classrooms in 2023, reading science being neglected in the adoption of Culkins' Units of Study curriculum, and other footballs like the supposed suppression of critical race theory in right leaning states.

    2. Her curriculum, “Units of Study,” is built on a vision of children as natural readers, and it has been wildly popular and profitable. She estimates that a quarter of the country’s 67,000 elementary schools use it. At Columbia University’s Teachers College, she and her team have trained hundreds of thousands of educators.

      Calkins' Units of Study curriculum has been estimated to be used by nearly 25% of the 67,000 elementary schools in the United States in 2023.

    1. Setting "img max-width:100%" is a technique employed in responsive/fluid web site design so that images re-size proportionally when the browser is re-sized. Apparently some css grid systems have started setting this style by default. More info about fluid images here: http://www.alistapart.com/articles/fluid-images/
    1. Now, our img element will render at whatever size it wants, as long as it’s narrower than its containing element. But if it happens to be wider than its container, then the max-width: 100% directive forces the image’s width to match the width of its container.

    1. ReconfigBehSci on Twitter: “but it is not vaccinated people that are disproportionately filling up ICUs. For any government whose policy is guided by ICU capacity, limiting the transmission possibilities for the unvaccinated is now the point. It is frustrating to see someone continue to ignore this” / Twitter. (n.d.). Retrieved December 23, 2021, from https://twitter.com/SciBeh/status/1471088416246878211

    1. With JavaScript, you can actually calculate the width of the scrollbar and whether it’s visible by comparing two properties—window.innerWidth and document.body.clientWidth. If these are equal, the scrollbar isn’t visible. If these are different, we can subtract the body width from the window width to get the width of the scrollbar:const scrollbarWidth = window.innerWidth - document.body.clientWidthWe’ll want to perform this both on page load and on resize, in case someone resizes the window vertically and changes the overflow. Then, once we have the scrollbar width, we can assign it as a CSS variable:document.body.setProperty("--scrollbarWidth", `${scrollbarWidth}px`)

      missing feature: vw/vh can't be used "directly" because doesn't account for scrollbars

    1. But I believe the core philosophy of tiny modules is actually sound and easier to maintain than giant frameworks.
    2. "Functions Are Not Packages" - Well why not?
    3. Small modules are extremely versatile and easy to compose together in an app with any number of other modules that suit your needs.
    4. Write modules that are small. Iterate quickly.

    1. 100vw is 100% of the viewport width not accounting for scrollbars (unless the root element has anything other than overflow: auto set, but auto is the default value). Thus, when the page content overflows the viewport vertically, the browser renders the vertical scroll bar, which reduces the visible viewport area by a few pixels. But the 100vw value doesn't update to account for this, so the selected div retains the same width as before the vertical scrollbar appeared. This results in the horizontal scroll bar rendering.
    1. Now, however, you set width:100vw and that is going to be (in this case) 100% wide (viewport wide) + the vertical scrollbar width. That’s too wide. That induces the HORIZONTAL scrollbar.
    1. Is a keyword that is identical to maximal content if it's a maximum. As a minimum it represents the largest minimum size (as specified by min-width/min-height) of the grid items occupying the grid track.

    1. Great, I can use vw to scale text so it doesn't look puny on a desktop! Perfect... Oh. Huh, now the text is too small to read when viewed on a phone. Okay, well I can just use "max(x,y)" to make sure it doesn't get shrunk beyond a minimum size. Perfect... Oh. Hmm. Looks like "max" isn't supported properly by Chrome. Okay, well guess I'll just use "px" again.
    1. It seems like this should be one of the easiest things to understand in CSS. If you want a block-level element to fill any remaining space inside of its parent, then it’s simple — just add width: 100% in your CSS declaration for that element, and your problem is solved. Not so fast. It’s not quite that easy. I’m sure CSS developers of all skill levels have attempted something similar to what I’ve just described, with bizarre results ultimately leading to head scratching and shruggingly resorting to experimenting with absolute widths until we find just the right fit. This is just one of those things in CSS that seems easy to understand (and really, it should be), but it’s sometimes not — because of the way that percentages work in CSS.
    1. You can read more about properly sizing the text using a combination of units along with the the calc() function in this excellent article about viewport unit-based typography.

    1. A literal number can take a suffix of wei, finney, szabo or ether to convert between the subdenominations of Ether, where Ether currency numbers without a postfix are assumed to be Wei, e.g. 2 ether == 2000 finney evaluates to true.

      1 ether = 1,000 Finney = 1,000,000 Szabo = 1,000,000,000 GWei = 1,000,000,000,000 MWei = 1,000,000,000,000,000 KWei = 1,000,000,000,000,000,000 Wei
