-At birth, Ged was given the child-name Duny by his mother. He was born on the island of Gont, as a son of a bronzesmith. His mother died before he reached the age of one. As a small boy, Ged had overheard the village witch, his maternal aunt, using various words of power to call goats. Ged later used the words without an understanding of their meanings, to surprising effect.
-
-The witch knew that using words of power effectively without understanding them required innate power, so she endeavored to teach him what little she knew. After learning more from her, he was able to call animals to him. Particularly, he was seen in the company of wild sparrowhawks so often that his "use name" became Sparrowhawk.

-summary: 'How to derive the OLS Estimator with matrix notation and a tour of math typesetting using markdown with the help of KaTeX.'
----
-
-# Introduction
-
-Parsing and display of math equations is included in this blog template. Parsing of math is enabled by `remark-math` and `rehype-katex`.
-KaTeX and its associated font is included in `_document.js` so feel free to use it on any page.
-[^footnote]
-
-[^footnote]: For the full list of supported TeX functions, check out the [KaTeX documentation](https://katex.org/docs/supported.html)
-
-Inline math symbols can be included by enclosing the term between the `$` symbol.
-
-Math code blocks are denoted by `$$`.
-
-If you intend to use the `$` sign instead of math, you can escape it (`\$`), or specify the HTML entity (`$`) [^2]
-
-Inline or manually enumerated footnotes are also supported. Click on the links above to see them in action.
-
-[^2]: \$10 and $20.
-
-# Deriving the OLS Estimator
-
-Using matrix notation, let $n$ denote the number of observations and $k$ denote the number of regressors.
-
-The vector of outcome variables $\mathbf{Y}$ is a $n \times 1$ matrix,
-
-```tex
-\mathbf{Y} = \left[\begin{array}
- {c}
- y_1 \\
- . \\
- . \\
- . \\
- y_n
-\end{array}\right]
-```
-
-$$
-\mathbf{Y} = \left[\begin{array}
- {c}
- y_1 \\
- . \\
- . \\
- . \\
- y_n
-\end{array}\right]
-$$
-
-The matrix of regressors $\mathbf{X}$ is a $n \times k$ matrix (or each row is a $k \times 1$ vector),
-
-```latex
-\mathbf{X} = \left[\begin{array}
- {ccccc}
- x_{11} & . & . & . & x_{1k} \\
- . & . & . & . & . \\
- . & . & . & . & . \\
- . & . & . & . & . \\
- x_{n1} & . & . & . & x_{nn}
-\end{array}\right] =
-\left[\begin{array}
- {c}
- \mathbf{x}'_1 \\
- . \\
- . \\
- . \\
- \mathbf{x}'_n
-\end{array}\right]
-```
-
-$$
-\mathbf{X} = \left[\begin{array}
- {ccccc}
- x_{11} & . & . & . & x_{1k} \\
- . & . & . & . & . \\
- . & . & . & . & . \\
- . & . & . & . & . \\
- x_{n1} & . & . & . & x_{nn}
-\end{array}\right] =
-\left[\begin{array}
- {c}
- \mathbf{x}'_1 \\
- . \\
- . \\
- . \\
- \mathbf{x}'_n
-\end{array}\right]
-$$
-
-The vector of error terms $\mathbf{U}$ is also a $n \times 1$ matrix.
-
-At times it might be easier to use vector notation. For consistency, I will use the bold small x to denote a vector and capital letters to denote a matrix. Single observations are denoted by the subscript.
-
-## Least Squares
-
-**Start**:
-$$y_i = \mathbf{x}'_i \beta + u_i$$
-
-**Assumptions**:
-
-1. Linearity (given above)
-2. $E(\mathbf{U}|\mathbf{X}) = 0$ (conditional independence)
-3. rank($\mathbf{X}$) = $k$ (no multi-collinearity i.e. full rank)
-4. $Var(\mathbf{U}|\mathbf{X}) = \sigma^2 I_n$ (Homoskedascity)
-
-**Aim**:
-Find $\beta$ that minimises the sum of squared errors:
-
-$$
-Q = \sum_{i=1}^{n}{u_i^2} = \sum_{i=1}^{n}{(y_i - \mathbf{x}'_i\beta)^2} = (Y-X\beta)'(Y-X\beta)
-$$
-
-**Solution**:
-Hints: $Q$ is a $1 \times 1$ scalar, by symmetry $\frac{\partial b'Ab}{\partial b} = 2Ab$.
-
-Take matrix derivative w.r.t $\beta$:
-
-```tex
-\begin{aligned}
- \min Q & = \min_{\beta} \mathbf{Y}'\mathbf{Y} - 2\beta'\mathbf{X}'\mathbf{Y} +
- \beta'\mathbf{X}'\mathbf{X}\beta \\
- & = \min_{\beta} - 2\beta'\mathbf{X}'\mathbf{Y} + \beta'\mathbf{X}'\mathbf{X}\beta \\
- \text{[FOC]}~~~0 & = - 2\mathbf{X}'\mathbf{Y} + 2\mathbf{X}'\mathbf{X}\hat{\beta} \\
- \hat{\beta} & = (\mathbf{X}'\mathbf{X})^{-1}\mathbf{X}'\mathbf{Y} \\
- & = (\sum^{n} \mathbf{x}_i \mathbf{x}'_i)^{-1} \sum^{n} \mathbf{x}_i y_i
-\end{aligned}
-```
-
-$$
-\begin{aligned}
- \min Q & = \min_{\beta} \mathbf{Y}'\mathbf{Y} - 2\beta'\mathbf{X}'\mathbf{Y} +
- \beta'\mathbf{X}'\mathbf{X}\beta \\
- & = \min_{\beta} - 2\beta'\mathbf{X}'\mathbf{Y} + \beta'\mathbf{X}'\mathbf{X}\beta \\
- \text{[FOC]}~~~0 & = - 2\mathbf{X}'\mathbf{Y} + 2\mathbf{X}'\mathbf{X}\hat{\beta} \\
- \hat{\beta} & = (\mathbf{X}'\mathbf{X})^{-1}\mathbf{X}'\mathbf{Y} \\
- & = (\sum^{n} \mathbf{x}_i \mathbf{x}'_i)^{-1} \sum^{n} \mathbf{x}_i y_i

-title: Images in Next.js
-date: '2020-11-11'
-tags: ['next js', 'guide']
-draft: false
-summary: 'In this article we introduce adding images in the tailwind starter blog and the benefits and limitations of the next/image component.'
-authors: ['sparrowhawk']
----
-
-# Introduction
-
-The tailwind starter blog has out of the box support for [Next.js's built-in image component](https://nextjs.org/docs/api-reference/next/image) and automatically swaps out default image tags in markdown or mdx documents to use the Image component provided.
-
-# Usage
-
-To use in a new page route / javascript file, simply import the image component and call it e.g.
-
-```js
-import Image from 'next/image'
-
-function Home() {
- return (
- <>
- {siteMetadata.author}
- {` • `}
- {`© ${new Date().getFullYear()}`}
+ {siteMetadata.author} {`© ${new Date().getFullYear()}`}
{` • `}
{siteMetadata.title}
My Homepage
-Welcome to my homepage!
- - ) -} - -export default Home -``` - -For a markdown file, the default image tag can be used and the default `img` tag gets replaced by the `Image` component in the build process. - -Assuming we have a file called `ocean.jpg` in `static/images/ocean.jpg`, the following line of code would generate the optimized image. - -``` - -``` - -Alternatively, since we are using mdx, we can just use the image component directly! Note, that you would have to provide a fixed width and height. The `img` tag method parses the dimension automatically. - -```js -{date}
- {title}
-{children}
- ` blocks.
-
-## Line highlighting and line numbers
-
-Line highlighting and line numbers are now supported out of the box thanks to the new [rehype-prism-plus plugin](https://github.com/timlrx/rehype-prism-plus)
-
-The following javascript code block:
-
-````
-```js {1, 3-4} showLineNumbers
-var num1, num2, sum
-num1 = prompt('Enter first number')
-num2 = prompt('Enter second number')
-sum = parseInt(num1) + parseInt(num2) // "+" means "add"
-alert('Sum = ' + sum) // "+" means combine into a string
-```
-````
-
-will appear as:
-
-```js {1,3-4} showLineNumbers
-var num1, num2, sum
-num1 = prompt('Enter first number')
-num2 = prompt('Enter second number')
-sum = parseInt(num1) + parseInt(num2) // "+" means "add"
-alert('Sum = ' + sum) // "+" means combine into a string
-```
-
-To modify the styles, change the following class selectors in the `prism.css` file:
-
-```css
-.code-highlight {
- @apply float-left min-w-full;
-}
-
-.code-line {
- @apply -mx-4 block border-l-4 border-opacity-0 pl-4 pr-4;
-}
-
-.code-line.inserted {
- @apply bg-green-500 bg-opacity-20;
-}
-
-.code-line.deleted {
- @apply bg-red-500 bg-opacity-20;
-}
-
-.highlight-line {
- @apply -mx-4 border-l-4 border-primary-500 bg-gray-700 bg-opacity-50;
-}
-
-.line-number::before {
- @apply -ml-2 mr-4 inline-block w-4 text-right text-gray-400;
- content: attr(line);
-}
-```
-
-## Newletter component (v1.1.3)
-
-Introduced in v1.1.3, the newsletter component gives you an easy way to build an audience. It integrates with the following providers:
-
-- [Mailchimp](https://mailchimp.com/)
-- [Buttondown](https://buttondown.email/)
-- [Convertkit](https://convertkit.com/)
-
-To use it, specify the provider which you are using in the config file and add the necessary environment variables to the `.env` file.
-For more information on the required variables, check out `.env.sample.`
-
-Two components are exported, a default `NewsletterForm` and a `BlogNewsletterForm` component, which is also passed in as an MDX component
-and can be used in a blog post:
-
-```jsx
-`
-2. Update the import at `pages/_app.js`- `import '@fontsource/.css'`
-3. Update the `fontfamily` property in the tailwind css config file
-
-## Upgrade guide
-
-There are significant portions of the code that has been changed from v0 to v1 including support for layouts and a new mdx engine.
-
-There's also no real reason to change if the previous one serves your needs and it might be easier to copy
-the component changes you are interested in to your existing blog rather than migrating everything over.
-
-Nonetheless, if you want to do so and have not changed much of the template, you could clone the new version and copy over the blog post over to the new template.
-
-Another alternative would be to pull the latest template version with the following code:
-
-```bash
-git remote add template git@github.com:timlrx/tailwind-nextjs-starter-blog.git
-git pull template v1 --allow-unrelated-histories
-rm -rf node_modules
-```
-
-You can see an example of such a migration in this [commit](https://github.com/timlrx/timlrx.com/commit/bba1c185384fd6d5cdaac15abf802fdcff027286) for my personal blog.
-
-v1 also uses `feed.xml` rather than `index.xml`, to avoid some build issues with Vercel. If you are migrating you should add a redirect to `next.config.js` like so:
-
-```js
-async redirects() {
- return [
- {
- source: '/:path/index.xml',
- destination: '/:path/feed.xml',
- permanent: true,
- }
- ]
-}
-```

----
-
-## Introduction
-
-Welcome to the release of Tailwind Nextjs Starter Blog template v2.0. This release is a major refactor of the codebase to support Nextjs App directory and React Server Components. Read on to discover the new features and how to migrate from V1.
-
-` and `` which takes in a configuration object and renders the appropriate component. Since the layouts are defined on the server side, Next.js is able to use the configuration object to determine which component to render and send only the required component bundle to the client.
-
-## New Search Component
-
-What's a blog in 2023 without a command palette search bar?
-
-One of the most highly requested features have been added 🎉! The search component supports 2 search providers - Algolia and Kbar local search.
-
-### Algolia
-
-[Algolia Docsearch](https://docsearch.algolia.com/) is popular free service used across many documentation websites. It automatically scrapes the website that has is submitted for indexing and makes the search result available via a beautiful dialog modal. The pliny component is greatly inspired by the Docusaurus implementation and comes with a stylesheet that is compatible with the Tailwind CSS theme.
-
-### Kbar
-
-[Kbar](https://github.com/timc1/kbar) is a fast, portable, and extensible cmd+k interface. The pliny implementation uses kbar to create a local search dialog box. The component loads a JSON file, default `search.json`, that was created in the contentlayer build process. Try pressing ⌘-k or ctrl-k to see the search bar in action!
-
-## Styling and Layout Updates
-
-### Theming
-
-`tailwind.config.js` has been updated to use tailwind typography defaults where possible and to use the built-in support for dark mode via the `prose-invert` class. This replaces the previous `prose-dark` class and configuration.
-
-The primary theme color is updated from `teal` to `pink` and the primary gray theme from `neutral` to `gray`.
-
-Inter is now replaced with Space Grotesk as the default font.
-
-### New Layouts
-
-Layout components available in the `layouts` directory, provide a simple way to customize the look and feel of the blog.[^2]
-
-The downside of building a popular template is that you start seeing multiple similar sites everywhere 😆. While users are encouraged to customized the layouts to their liking, having more layout options that are easily switchable promotes diversity and perhaps can be a good starting point for further customizations.
-
-In v2, I added a new post layout - `PostBanner`. It features a large banner image and a centered content container. Check out "[Pictures of Canada](/blog/pictures-of-canada)" blog post which has been updated to use the new layout.
-
-The default blog listing layout has also been updated to include a side bar with blog tags. The search bar in the previous layout has been replace with the new command palette search. To switch back to the old layout, simply change the pages that use the `ListLayoutWithTags` component back to the original `ListLayout`.
-
-## Migration Recommendations
-
-Due to the large changes in directory structure, setup and tooling, I recommend starting from a fresh template and copying existing content, followed by incrementally migrating changes over to the new template.
-
-Styling changes should be relatively minor and can be copied over from the old `tailwind.config.js` to the new one. If copying over, you might need to add back the `prose-dark` class to components that opt into tailwind typography styling. Do modify the font import in the root layout component to use the desired font of choice.
-
-Changes to the MDX processing pipeline and schema can be easily ported to the new Contentlayer setup. If there are changes to the frontmatter fields, you can modify the document type in `contentlayer.config.ts` to include the new fields. Custom plugins can be added to the `remarkPlugins` and `rehypePlugins` properties in the `makeSource` export of `contentlayer.config.ts`.
-
-Markdown layouts are no longer sourced automatically from the `layouts` directory. Instead, they have to be specified in the `layouts` object defined in `blog/[...slug]/page.tsx`.[^3]
-
-To port over larger components or pages, I recommend first specificing it as a client component by using the `"use client"` directive. Once it renders correctly, you can split the interactive components (parts that rely on `use` hooks) as a client component and keep the remaining code as a server component. Consult the comprehensive Next.js [migration guide](https://nextjs.org/docs/app/building-your-application/upgrading/app-router-migration#migrating-from-pages-to-app) for more details.
-
-## Conclusion
-
-I hope you enjoy the new features and improvements in V2. If you have any feedback or suggestions, feel free to open an issue or reach out to me on [Twitter](https://twitter.com/timlrx).

-[^1]: The previous version injects Preact into the production build. However, this is no longer possible as it does not support React Server Components. While overall bundle size has increased to about 85kB, most of the content can be pre-rendered on the server side, resulting in a low first contentful paint and time to interactive. Using React throughtout also leads to more consistent behavior with external libraries and components.
-[^2]: This is different from Next.js App Directory layouts and are best thought of as reusable React containers.
-[^3]: This takes advantage of Server Components by making it simple to specify the layout of choice in the markdown file and match against the `layouts` object which is then used to render the appropriate layout component.

-## Introduction
-
-The Time Traveller (for so it will be convenient to speak of him) was
-expounding a recondite matter to us. His pale grey eyes shone and
-twinkled, and his usually pale face was flushed and animated. The fire
-burnt brightly, and the soft radiance of the incandescent lights in the
-lilies of silver caught the bubbles that flashed and passed in our
-glasses. Our chairs, being his patents, embraced and caressed us rather
-than submitted to be sat upon, and there was that luxurious
-after-dinner atmosphere, when thought runs gracefully free of the
-trammels of precision. And he put it to us in this way—marking the
-points with a lean forefinger—as we sat and lazily admired his
-earnestness over this new paradox (as we thought it) and his fecundity.
-
-“You must follow me carefully. I shall have to controvert one or two
-ideas that are almost universally accepted. The geometry, for instance,
-they taught you at school is founded on a misconception.”
-
-“Is not that rather a large thing to expect us to begin upon?” said
-Filby, an argumentative person with red hair.
-
-“I do not mean to ask you to accept anything without reasonable ground
-for it. You will soon admit as much as I need from you. You know of
-course that a mathematical line, a line of thickness _nil_, has no real
-existence. They taught you that? Neither has a mathematical plane.
-These things are mere abstractions.”
-
-“That is all right,” said the Psychologist.
-
-“Nor, having only length, breadth, and thickness, can a cube have a
-real existence.”
-
-“There I object,” said Filby. “Of course a solid body may exist. All
-real things—”
-
-“So most people think. But wait a moment. Can an _instantaneous_ cube
-exist?”
-
-“Don’t follow you,” said Filby.
-
-“Can a cube that does not last for any time at all, have a real
-existence?”
-
-Filby became pensive. “Clearly,” the Time Traveller proceeded, “any
-real body must have extension in _four_ directions: it must have
-Length, Breadth, Thickness, and—Duration. But through a natural
-infirmity of the flesh, which I will explain to you in a moment, we
-incline to overlook this fact. There are really four dimensions, three
-which we call the three planes of Space, and a fourth, Time. There is,
-however, a tendency to draw an unreal distinction between the former
-three dimensions and the latter, because it happens that our
-consciousness moves intermittently in one direction along the latter
-from the beginning to the end of our lives.”
-
-“That,” said a very young man, making spasmodic efforts to relight his
-cigar over the lamp; “that . . . very clear indeed.”
-
-“Now, it is very remarkable that this is so extensively overlooked,”
-continued the Time Traveller, with a slight accession of cheerfulness.
-“Really this is what is meant by the Fourth Dimension, though some
-people who talk about the Fourth Dimension do not know they mean it. It
-is only another way of looking at Time. _There is no difference between
-Time and any of the three dimensions of Space except that our
-consciousness moves along it_. But some foolish people have got hold of
-the wrong side of that idea. You have all heard what they have to say
-about this Fourth Dimension?”
-
-“_I_ have not,” said the Provincial Mayor.
-
-“It is simply this. That Space, as our mathematicians have it, is
-spoken of as having three dimensions, which one may call Length,
-Breadth, and Thickness, and is always definable by reference to three
-planes, each at right angles to the others. But some philosophical
-people have been asking why _three_ dimensions particularly—why not
-another direction at right angles to the other three?—and have even
-tried to construct a Four-Dimensional geometry. Professor Simon Newcomb
-was expounding this to the New York Mathematical Society only a month
-or so ago. You know how on a flat surface, which has only two
-dimensions, we can represent a figure of a three-dimensional solid, and
-similarly they think that by models of three dimensions they could
-represent one of four—if they could master the perspective of the
-thing. See?”
-
-“I think so,” murmured the Provincial Mayor; and, knitting his brows,
-he lapsed into an introspective state, his lips moving as one who
-repeats mystic words. “Yes, I think I see it now,” he said after some
-time, brightening in a quite transitory manner.
-
-“Well, I do not mind telling you I have been at work upon this geometry
-of Four Dimensions for some time. Some of my results are curious. For
-instance, here is a portrait of a man at eight years old, another at
-fifteen, another at seventeen, another at twenty-three, and so on. All
-these are evidently sections, as it were, Three-Dimensional
-representations of his Four-Dimensioned being, which is a fixed and
-unalterable thing.
-
-“Scientific people,” proceeded the Time Traveller, after the pause
-required for the proper assimilation of this, “know very well that Time
-is only a kind of Space. Here is a popular scientific diagram, a
-weather record. This line I trace with my finger shows the movement of
-the barometer. Yesterday it was so high, yesterday night it fell, then
-this morning it rose again, and so gently upward to here. Surely the
-mercury did not trace this line in any of the dimensions of Space
-generally recognised? But certainly it traced such a line, and that
-line, therefore, we must conclude, was along the Time-Dimension.”
-
-“But,” said the Medical Man, staring hard at a coal in the fire, “if
-Time is really only a fourth dimension of Space, why is it, and why has
-it always been, regarded as something different? And why cannot we move
-in Time as we move about in the other dimensions of Space?”
-
-The Time Traveller smiled. “Are you so sure we can move freely in
-Space? Right and left we can go, backward and forward freely enough,
-and men always have done so. I admit we move freely in two dimensions.
-But how about up and down? Gravitation limits us there.”
-
-“Not exactly,” said the Medical Man. “There are balloons.”
-
-“But before the balloons, save for spasmodic jumping and the
-inequalities of the surface, man had no freedom of vertical movement.”
-
-“Still they could move a little up and down,” said the Medical Man.
-
-“Easier, far easier down than up.”
-
-“And you cannot move at all in Time, you cannot get away from the
-present moment.”
-
-“My dear sir, that is just where you are wrong. That is just where the
-whole world has gone wrong. We are always getting away from the present
-moment. Our mental existences, which are immaterial and have no
-dimensions, are passing along the Time-Dimension with a uniform
-velocity from the cradle to the grave. Just as we should travel _down_
-if we began our existence fifty miles above the earth’s surface.”
-
-“But the great difficulty is this,” interrupted the Psychologist. ’You
-_can_ move about in all directions of Space, but you cannot move about
-in Time.”
-
-“That is the germ of my great discovery. But you are wrong to say that
-we cannot move about in Time. For instance, if I am recalling an
-incident very vividly I go back to the instant of its occurrence: I
-become absent-minded, as you say. I jump back for a moment. Of course
-we have no means of staying back for any length of Time, any more than
-a savage or an animal has of staying six feet above the ground. But a
-civilised man is better off than the savage in this respect. He can go
-up against gravitation in a balloon, and why should he not hope that
-ultimately he may be able to stop or accelerate his drift along the
-Time-Dimension, or even turn about and travel the other way?”
-
-“Oh, _this_,” began Filby, “is all—”
-
-“Why not?” said the Time Traveller.
-
-“It’s against reason,” said Filby.
-
-“What reason?” said the Time Traveller.
-
-“You can show black is white by argument,” said Filby, “but you will
-never convince me.”
-
-“Possibly not,” said the Time Traveller. “But now you begin to see the
-object of my investigations into the geometry of Four Dimensions. Long
-ago I had a vague inkling of a machine—”
-
-“To travel through Time!” exclaimed the Very Young Man.
-
-“That shall travel indifferently in any direction of Space and Time, as
-the driver determines.”
-
-Filby contented himself with laughter.
-
-“But I have experimental verification,” said the Time Traveller.
-
-“It would be remarkably convenient for the historian,” the Psychologist
-suggested. “One might travel back and verify the accepted account of
-the Battle of Hastings, for instance!”
-
-“Don’t you think you would attract attention?” said the Medical Man.
-“Our ancestors had no great tolerance for anachronisms.”
-
-“One might get one’s Greek from the very lips of Homer and Plato,” the
-Very Young Man thought.
-
-“In which case they would certainly plough you for the Little-go. The
-German scholars have improved Greek so much.”
-
-“Then there is the future,” said the Very Young Man. “Just think! One
-might invest all one’s money, leave it to accumulate at interest, and
-hurry on ahead!”
-
-“To discover a society,” said I, “erected on a strictly communistic
-basis.”
-
-“Of all the wild extravagant theories!” began the Psychologist.
-
-“Yes, so it seemed to me, and so I never talked of it until—”
-
-“Experimental verification!” cried I. “You are going to verify _that_?”
-
-“The experiment!” cried Filby, who was getting brain-weary.
-
-“Let’s see your experiment anyhow,” said the Psychologist, “though it’s
-all humbug, you know.”
-
-The Time Traveller smiled round at us. Then, still smiling faintly, and
-with his hands deep in his trousers pockets, he walked slowly out of
-the room, and we heard his slippers shuffling down the long passage to
-his laboratory.
-
-The Psychologist looked at us. “I wonder what he’s got?”
-
-“Some sleight-of-hand trick or other,” said the Medical Man, and Filby
-tried to tell us about a conjuror he had seen at Burslem, but before he
-had finished his preface the Time Traveller came back, and Filby’s
-anecdote collapsed.
