If you want to add the cs files from one Visual Studio solution (or project) into another, without duplicating the cs files or moving them over, you can simply use the Add > Existing file.. option, making sure that instead of selecting the files and clicking Add (which would copy the files over to your project folder duplicating them) you click on the small arrow and click Add As Link. The files will be linked to your project as a reference to the other project, and editing them will change their code for both Visual Studio projects.

The short answer is that you can't. But there's a workaround.

Let's say you have a newsletter design as follows, which shows the post image, followed by its title and full content.

*|RSSITEM:IMAGE|*

*|RSSITEM:TITLE|*

*|RSSITEM:CONTENT_FULL|*

The *|RSSITEM:IMAGE|* RSS merge tag will pull in the image and assign to the the created img element the width and height corresponding to the original size of the image. Something like this (which is an example extracted from my Mailchimp campaign using the design template above).

<img class="mc-rss-item-img" src="https://nono.ma/img/u/sketch-170202_cambridge-clary-st.jpg" height="1868" width="2500" style="height: 1868;width: 2500;">

The problem is that we don't want to explicitly specify the height and width values of our image, as its oversized compared to the width of our design, which in my example was 600px plus margins, which was leaving 564px for the width of the image itself.

Here's the workaround: You create the image's img HTML element yourself, formatting it as you want, and use the RSSITEM:ENCLOSURE_URL—which according to Mailchimp "Displays the URL for the attached file [of your post]." In my case, the RSS feed is using the enclosure tag to send the image URL.

// RSS feed item enclosure tag
<enclosure url="https://nono.ma/img/u/sketch-170202_cambridge-clary-st.jpg" type="image/jpeg"/>

Then I can use that URL in my Mailchimp design as follows (also adding the post's title and full content below the image).

<img src="*|RSSITEM:ENCLOSURE_URL|*" style="max-width: 100%">

*|RSSITEM:TITLE|*

*|RSSITEM:CONTENT_FULL|*

As a security mechanism, Windows natively lets you unzip files by right-clicking and choosing Extract All.. Well, you can skip the manual unblocking of the files by using 7-Zip to extract the files instead of Windows’ mechanism.

We want to get rid of a message you might have seen over and over when downloading files from the internet. "This file came from another computer and might be blocked to help protect this computer," next to an Unblock button. If you know about this, it's fine to unblock a couple files, but it's really annoying when you download a zip containing dozens of files which you have to unblock individually, one by one.

Download and install 7-Zip and unzip downloaded plugins with right-click > 7-Zip > Extract here, or any of the other extraction options.

This issue has given me a lot of headaches when installing both Dynamo and Grasshopper plugins, but you might run into this issue in other environments as well. I'm glad there's an alternative to unlocking each file--might it be DLL, gha, gh, dyn, PDF, exe or files in another formats--separately, unzipping a group of files, all unlocked, at once.

By default NPM—the Node Package Manager—uses its own public registry (at https://registry.npmjs.org) to pull down packages when you run npm install or npm update inside of a project.

You can specify different registries at multiple levels or scopes to override these default value (and other configuration settings). Ideally, when working on projects that require a specific registry—due to security or maybe just because some packages are inside of a private repository—you would set NPM to look for packages on that registry inside of the project folder.

Command level (only affects the command itself)

npm install --registry=https://some.registry.url

Project level (these would be the contents of the .npmrc file inside of the project folder)

registry=https://some.registry.url
@namespace:registry=https://some.other.registry.url

Global (these would be the contents of the .npmrc file inside of your system user folder)

registry=https://some.registry.url
@namespace:registry=https://some.other.registry.url

How to check your configuration is working

Run the npm config list command to see what variables are set. If you run this in a project folder with an .npmrc file you should see its overriding configuration settings in the folder, and the system global settings after that.

If you run the command in any other folder (without an .npmrc file with custom settings) you should see whatever is set in the global .npmrc and then the default configuration values of NPM.

A cheat-sheet for mathematical notation in [JavaScript] code form.

Today I've automated the backup of the configuration, database, and static files of all the websites I manage. Two hours and a half that will save me a lot of time in the coming future, and remove stress when weird things happen. The backup—of six websites in three different servers running Laravel—downloads a copy of the database, the .env files, and the static files (a zip with the contents of the public folder) of each site.

I'll probably open source these scripts in the near future.

One new thing I learned was creating bash functions, like this one.

# create a variable with current date, formatted as yymmdd_HHMMSS
DATE_NOW=$(date '+%y%m%d_%H%M%S') 

# function that zips something and removes it
zip_and_remove() { cd $1 && zip "$2.zip" $2 && rm $2 && cd .. }

# function that downloads a file via ssh then calls the previous one
download_zip_remove() { scp $1 $2/$3 && zip_and_remove $2 $3  }

# a function call
download_zip_remove root@192.168.1.2:/var/www/site.com/folio/.env $DESTINATION $(echo $DATE_NOW)_$SITENAME.env

Revit allows you to import PDF and image files from its Ribbon menu. After clicking either button (Import PDF or Import Image) you get the same window, really, just with a different extension pre-selected.

You import a file and place it into a view, and if the file happens to be a PDF file you select a page and a rasterization resolution (in DPI).

Internally, Revit uses the PDFNet library made by PDFTron to manipulate PDF files. One of the operations it seems to use it for is to rasterize the contents of a PDF to be able to display it on a view. This process makes the image data (of the image itself or a rasterized PDF) available inside of Revit. By using the Revit Lookup add-in, I found that the ImageType class offers a GetImage() method which returns a Bitmap object containing that image data.

Remember that, when you pick an existing imported image or PDF, you are selecting what's called an object of the ImageInstance class, which wraps an ImageType object. So we need to get the ImageInstance element, access its ImageType, then get its image data.

Let's see the code.

// This code goes somewhere in your Revit add-in
// Prompt user to pick a Revit Element
Reference pickedObject = UIDoc.Selection.PickObject(Autodesk.Revit.UI.Selection.ObjectType.Element);

// Get Element
Element element = Doc.GetElement(pickedObject.ElementId);

// Get Element Type
ElementId elementTypeId = element.GetTypeId();
ElementType elementType = Doc.GetElement(elementTypeId) as ElementType;

// Do something if object selection exists
if (pickedObject != null)
{
    // Check if picked element is an ImageInstance
    if (element is ImageInstance)
    {
        // Cast types for ImageInstance and ImageType
        // ImageType Id = ImageInstance Id - 1
        ImageInstance image = element as ImageInstance;
        ImageType imageType = elementType as ImageType;

        // Get image properties
        var filename = image.Name; // eg. FloorPlan.pdf

        // Get imported file path from ImageType
        var filepath = imageType.get_Parameter(BuiltInParameter.RASTER_SYMBOL_FILENAME).AsString();
        var pixelWidth = imageType.get_Parameter(BuiltInParameter.RASTER_SYMBOL_PIXELWIDTH).AsInteger();
        var pixelHeight = imageType.get_Parameter(BuiltInParameter.RASTER_SYMBOL_PIXELHEIGHT).AsInteger();

        // Get image data
        Bitmap bitmap = imageType.GetImage();

        // Save image to disk
        bitmap.Save(@"C:\users\username\Desktop\image.bmp");
    }
}

If you are inside of a function which uses a type parameter—T—you can do a Console.WriteLine, for instance, to inspect what type is being used on a given function call.

Console.WriteLine(typeof(T));
// System.object or other type

This example uses regular expressions (RegExp) to replace multiple appearances of a substring in a string.

const string = `The car is red. The car is black.`;

const replacedString = string.replace(/car|is/g, "·····");

console.log(replacedString);
// returns The ····· ····· red. The ····· ····· black.

Here is an example of nested Promise.all() calls. We are using the Fetch API to load a given path or URL, then requesting the arrayBuffer() of each of the responses we get back. This is a trivial problem if we do it all asynchronously, but we want to do something with the output buffers when we have them all available, and not one by one.

Specifically, this code tries to (1) fetch an array of images; (2) get their array buffers; (3) then obtain their base64 representation. In essence, map an array of images (by providing their paths or URLs) to their corresponding base64 string.

While this technique works in both TypeScript and JavaScript, the code is only shown in TypeScript.

Approach 1: Verbose

const images = [/* Array of image URLs (or local path if running in Electron) */]

Promise.all(images.map((url) => fetch(url))).then((responses: any) => {

    return Promise.all(responses.map((res: Response) => res.arrayBuffer())).then((buffers) => {
        return buffers;
    });

}).then((buffers: any) => {

    return Promise.all(buffers.map((buffer: ArrayBuffer) => {
        return this.arrayBufferToBase64(buffer);
    }));

}).then((imagesAsBase64: any) => {

    // Do something with the base64 strings
    window.console.log(imagesAsBase64);

});

Approach 2: Simplified

const layerImages = [/* Array of image URLs (or local path if running in Electron) */]

Promise.all(layerImages.map((url) => fetch(url))).then((responses: any) => {

    return Promise.all(responses.map((res: Response) => res.arrayBuffer())).then((buffers) => {
        return buffers.map((buffer) => this.arrayBufferToBase64(buffer));
    });

}).then((imagesAsBase64: any) => {

    // Do something with the base64 strings
    window.console.log(imagesAsBase64);

});

Array Buffer to base64

// source: stackoverflow.com
private arrayBufferToBase64(buffer: any) {
    let binary = "";
    const bytes = [].slice.call(new Uint8Array(buffer));
    bytes.forEach((b: any) => binary += String.fromCharCode(b));
    // Inside of a web tab
    return window.btoa(binary);
}

Yay! Visual Studio just announce a preview release of "extension [that] let you work with [Visual Studio] Code over SSH on a remote machine or VM, in Windows Subsystem for Linux (WSL), or inside a Docker container."

Go ahead and install the Remote Development extension. "An extension pack that lets you open any folder in a container, on a remote machine, or in WSL and take advantage of VS Code's full feature set."

A while ago we had the need to grab the App window variable (exposed by CefSharp) and we were extending the Window interface to do that. There seems to be a better way to get variables that are define in the Window environment.

I learned this from this link An advanced guide on how to setup a React and PHP.

If you are defining a variable or object you want to read from React (like in CefSharp, o directly in the HTML like in the screenshot)

// inside of your app entry HTML file's header
<script>
var myApp = {
  user: "Name",
  logged: true
}
</script>

You can do a declare module 'myApp' in index.d.ts, then add the myApp variable as a external library in Webpack's config file

externals: {
  myApp: `myApp`,
},

Then you can import as if it was a module in TypeScript (or JavaScript files) with React

import myApp from 'myApp';

And you can even use TypeScript destructuring technique to get internal properties directly

const { user: { name, email}, logged } = myApp;

In trying to export my React's Redux store from index.tsx to be used somewhere else outside of the React application, I was getting an Invariant Violation: Target container is not a DOM element error while running Jest tests (with Enzyme and Webpack) in the App component (App.tsx).

I found a solution to this error for my use case, which was using the same Redux store React is using outside of React.

The error

The initial code that didn't work when testing React looked like this.

// index.tsx

import * as React from "react";
import { render } from "react-dom";
import { Provider } from "react-redux";
import { applyMiddleware, compose, createStore } from "redux";
import App from "./components/App";
import { rootReducer } from "./store/reducers";
import { initialState } from "./store/state";

const middlewares = [];

export const store = createStore(
    rootReducer,
    initialState,
    compose(applyMiddleware(...middlewares)),
);

render(
    <Provider store={store}>
        <App />
    </Provider>,
    document.getElementById("root"),
);

The solution

Separate the Redux store logic into a new file named store.ts, then create a default export (to be used by index.tsx, i.e., the React application) and a non-default export with export const store (to be used from non-React classes), as follows.

// store.ts

import { applyMiddleware, compose, createStore } from "redux";
import logger from "redux-logger";
import { rootReducer } from "./store/reducers";
import { initialState } from "./store/state";

const middlewares = [];

export const store = createStore(
    rootReducer,
    initialState,
    compose(applyMiddleware(...middlewares)),
);

export default store;

// updated index.tsx

import * as React from "react";
import { render } from "react-dom";
import { Provider } from "react-redux";
import App from "./components/App";
import store from "./store";

render(
    <Provider store={store}>
        <App />
    </Provider>,
    document.getElementById("root"),
);

Using the Redux store in non-React classes

// MyClass.ts

import { store } from "./store"; // store.ts

export default class MyClass {
  handleClick() {
    store.dispatch({ ...new SomeAction() });
  }
}

The default export

A small note before you go. Here is how to use the default and the non-default exports.

• default export store; is used with import store from "./store";
• export const store = ... is used with import { store } from "./store";

Here are my highlights of Deep dive into Electron’s main and renderer processes by Cameron Nokes.

[Each of these processes is] an operative system level process, or as Wikipedia puts it "an instance of a computer program that is being execute."

[…] Each of these processes run concurrently to each other. […] [M]emory and resources are isolated from each other. […] The two processes don't share memory or state.

Why multiple processes?

Chromium runs each tab in a separate process so that if one tab runs into a fatal error, it doesn't bring down the entire application. […] "Chromium is built like an operative system, using multiple OS processes to isolate web sites from each other and from the browser itself."

Main process

[I]s responsible for creating and managing BrowserWindow instances and various application events. It can also register global shortcuts, creative native menus and dialogs, respond to auto-update events, and more. Your app's entry point will point to a JavaScript file that will be executed in the main process. A subset of Electron APIs are available in the main process, as well as all Node.js modules. The docs state: “The basic rule is: if a module is GUI or low-level system related, then it should be only available in the main process.” (Note that GUI here means native GUI, not HTML based UI rendered by Chromium). This is to avoid potential memory leak problems.

Renderer process

The render process is responsible for running the user-interface of your app, or in other words, a web page which is an instance of webContents. All DOM APIs, Node.js APIs, and a subset of Electron APIs are available in the renderer. […] [O]ne or more webContents can live in a single window […] because a single window can host multiple webviews and each webview is its own webContents instance and renderer process.

See this Venn diagram of Electron (provided by the source).

How do I communicate between processes?

Electron uses interprocess communication (IPC) to communicate between processes—same as Chromium. IPC is sort of like using postMessage between a web page and an iframe or webWorker […] you send a message with a channel name and some arbitrary information. IPC can work between renderers and the main process in both directions. IPC is asynchronous by default but also has synchronous APIs (like fs in Node.js).

Electron also gives you the remote module, which allows you to, for example, use a main process module like Menu as if it were available in the renderer. No manual IPC calls [are] necessary, but what's really going on behind the scenes is that you are issuing commands to the main process via synchronous IPC calls. (These can be debugged with devtron.)

Can I make something work in both the main and renderer?

Yes, because main process APIs can be accessed through remote, you can do something like this:

const electron = require('electron');
const Menu = electron.Menu || electron.remote.Menu;

//now you can use it seamlessly in either main or renderer

console.log(Menu);

(See the full thing.)

Here's a note on how to display dialogs, alerts, and notifications on macOS with AppleScript, useful to automate day-to-day tasks you do with your machine, or even create complex programs.

(To the uninitiated, you would run this code by opening the AppleScript Editor (on macOS), pasting the code there, and hitting run.)

Dialog and Alert¹

display alert "This is an alert" buttons {"No", "Yes"}
if button returned of result = "No" then
    display alert "No was clicked"
else
    if button returned of result = "Yes" then
        display alert "Yes was clicked"
    end if
end if

System notification

display notification "Have a simple day!"

After cloning a repository, you can have git not track changes you make to one (or multiple) files.

Tell Git to assume a file is unchanged

git update-index --assume-unchanged file

Tell Git not to assume a file is unchanged anymore

After this command is run, the repository continues tracking the file. It might have changes that git will want to commit.

git update-index --no-assume-unchanged file

Roll back the changes you made while the file was --assume-unchanged

In case you made changes while --assume-unchanged was on and don't want to keep the changes on the file: Roll-back to where the repository is when you want to pull or push changes.

git checkout -- file

const numbers = [1, 3, 100, 24];
for (const item of numbers) {
  console.log(item); // 1, 3, 100, 24

GitHub just released GitHub Actions, to "automate your workflow from idea to production." Their slogan:

Focus on what matters: code

Here are some comments by Sarah Drasner on CSS-Tricks:

Previously, there were only few options here that could help with that. You could piece together other services, set them up, and integrate them with GitHub. You could also write post-commit hooks, which also help.

[...]

Actions are small bits of code that can be run off of various GitHub events, the most common of which is pushing to master. But it's not necessarily limited to that. They’re all directly integrated with GitHub, meaning you no longer need a middleware service or have to write a solution yourself. And they already have many options for you to choose from. For example, you can publish straight to npm and deploy to a variety of cloud services, (Azure, AWS, Google Cloud, Zeit... you name it) just to name a couple.

But actions are more than deploy and publish. That’s what’s so cool about them. They’re containers all the way down, so you could quite literally do pretty much anything — the possibilities are endless! You could use them to minify and concatenate CSS and JavaScript, send you information when people create issues in your repo, and more... the sky's the limit.

You also don’t need to configure/create the containers yourself, either. Actions let you point to someone else’s repo, an existing Dockerfile, or a path, and the action will behave accordingly. This is a whole new can of worms for open source possibilities, and ecosystems.

Curious about how this all works? Take a look at CSS-Tricks tutorials:

• Setting up your first action
• Writing an action in code
• Creating a custom action

Here are some notes I took while reading GitHub's An Introduction to innersource white paper.

Organizations worldwide are incorporating open source methodologies into the way they build and ship their own software. […]

Many companies use the word “innersource” to describe how their engineering teams work together on code. Innersource is a development methodology where engineers build proprietary software using best practices.

[…]

[I]nnersource code helps your team discover, customize, and reuse existing internal projects. They can also establish and build on a shared set of documented processes to optimize the way your company deploys and uses software. This can lead to lower cost, greater flexibility, and an end to vendor lock-in.

[…]

Within an enterprise, individual developers can pursue their interests, share ideas on a level playing field, and more easily learn from their peers. However, innersource also requires a cultural shift. Your team’s culture will need to encourage knowledge sharing and welcome contributions from across your organization. […] For innersource projects, distributing control across a smaller group of participants frequently makes approvals and reviews more effective. Creating a small, cross-functional team of decision makers can also help teams stick to quality standards and gain executive support.
Adopting innersource practices is like starting an open source community within your organization. As with open source, transparent collaboration mobilizes a community’s collective knowledge and skills to create better software. An innersource community, in contrast, contains the knowledge, skills, and abilities of people and tools within a single enterprise.

Why do companies adopt it?

As businesses evolve and differentiate their products and services with software and data—or recognize software and data is their product or service—they quickly realize that traditional development methods and tooling don’t quite work. The slow, systematic practice of gathering requirements, holding meetings, and developing in silos is not in step with the pace of technology today—or even the pace of customer demands.
Innersource helps teams build software faster and work better together—resulting in higher-quality development and better documentation. It also can help companies become more efficient by:

• Making it easy to find and reuse code on a broad scale, avoiding wasted resources and duplication
• Driving rapid development, regardless of company size
• Reducing silos and simplifying collaboration throughout the entire organization—inside and between teams and functions, as well as across teams and business lines
• Increasing clarity between engineers and management, as well as anyone else who’s interested
• Creating a culture of openness, a precursor to open source participation
• Reinforcing the pride, growth, and job satisfaction felt by team members who help wherever there is a need

This year, the ACADIA conference is taking place at UNAM's Facultad de Arquitectura, Mexico City. As part of the Talk to a Wall workshop, Cristobal Valenzuela (@c_valenzuelab) talked about his work on RunwayML, ml5js, and a lot of what's going on at the moment on the field of artificial intelligence, machine learning, and deep learning.

Along his definition of artificial intelligence, "[The] simulation of intelligent behavior in computers," he shared the following quotes of some of the most relevant researchers of artificial intelligence over the last years.

Models for Thinking, Perception, Action.

—Patrick H. Winston, MIT

Many things can be AI, including simple programming. AI is the automation of thought.

—François Chollet, researcher and author of Keras

A field of study that gives computers the ability to learn without being explicitly programmed.

If you're interested in artificial intelligence and machine learning, you should definitely follow @c_valenzuelab, @ml5js, and @runwayml.

Lobe is a web-based visual programming language to create and deploy machine learning models, founded in 2015 by Mike Matas, Adam Menges, and Markus Beissinger "to make deep learning accessible to everyone," recently acquired by Microsoft.

Lobe is an easy-to-use visual tool that lets you build custom deep learning models, quickly train them, and ship them directly in your app without writing code.

I saw a live demo at SmartGeometry earlier this year and I can't wait to play with it once its deployed on Microsoft's servers.

You can see a few examples at Lobe.ai. (They're looking for people to join their team.)

In TypeScript, as in other languages, Array.map allows you to apply a function to each of the items on a list or array. You can either pass an existing function which will take each of the items as its input parameter (say, the existing Math.sqrt function, or one that you define).

let list = [0, 1, 2, 3]; // [0, 1, 2, 3]
list.map(Math.sqrt); // [ 0, 1, 1.414.., 1.732.. ]

Or you can also define a lambda function on-the-go.

let list = [0, 1, 2, 3]; // [0, 1, 2, 3]
list.map((value, key, all) => {
  list[key] = value * 2;
}); // [ 0, 2, 4, 6]

There is a nifty way to specify the way in which you want each of the pages (or Laravel routes) of your site to be indexed by search engines. In my case, I looked Robots meta tag and X-Robots-Tag HTTP header specifications to learn more about what was possible.

In short, you might tell Google a specific route or page has "no restrictions for indexing or serving" by setting the X-Robots-Tag HTTP header to all or, on the contrary, tell it to stop indexing (or saving cached versions of a page) with the noindex value.

In Laravel, the guys at Spatie made it really easy. Just install their spatie/laravel-robots-middleware composer package on your Laravel app with:

composer require spatie/laravel-robots-middleware

Let's see a few examples on how to use this.

Allow every single page to be indexed and served

Create a new middleware in your application.

// app/Http/Middleware/MyRobotsMiddleware.php

<?php
namespace App\Http\Middleware;
use Illuminate\Http\Request;
use Spatie\RobotsMiddleware\RobotsMiddleware;

class MyRobotsMiddleware extends RobotsMiddleware
{
    /**
     * @return string|bool
     */
    protected function shouldIndex(Request $request)
    {
        return 'all';
    }
}

And then register your new in the middleware stack.

// app/Http/Kernel.php

class Kernel extends HttpKernel
{
    protected $middleware = [
        // ...
        \App\Http\Middleware\MyRobotsMiddleware::class,
    ];

    // ...
}

Forbid every single from being indexed, cached, and served

// app/Http/Middleware/BlockAllRobotsMiddleware.php

<?php
namespace App\Http\Middleware;
use Illuminate\Http\Request;
use Spatie\RobotsMiddleware\RobotsMiddleware;

class BlockAllRobotsMiddleware extends RobotsMiddleware
{
    /**
     * @return string|bool
     */
    protected function shouldIndex(Request $request)
    {
        return 'noindex';
    }
}

Conditional robots middleware

Probably, the most interesting application of this middleware is to embed more intelligent logic to avoid indexing specific pages, but letting Google (and other search engines) crawl the pages you want to expose in search engines.

We could send a noindex header for our admin pages only, for instance.

// app/Http/Middleware/SelectiveRobotsMiddleware.php

<?php
namespace App\Http\Middleware;
use Illuminate\Http\Request;
use Spatie\RobotsMiddleware\RobotsMiddleware;

class SelectiveRobotsMiddleware extends RobotsMiddleware
{
    protected function shouldIndex(Request $request) : string
    {
        if ($request->segment(1) === 'admin') {
            return 'noindex';
        }
        return 'all';
    }
}

Remember that you need to add all of your new middlewares to the app/Http/Kernel.php file in order for them to be called before each request. This method can be handing to block search indexing with noindex or to customize the way search engines are allow to process your pages. Here are other directives you can use in the x-robots-tag HTTP header and what they mean.

• all - There are no restrictions for indexing or serving. Note: this directive is the default value and has no effect if explicitly listed.
• noindex - Do not show this page in search results and do not show a "Cached" link in search results.
• nofollow - Do not follow the links on this page

ViveTrack is a DynamoBIM package that allows real-time reading of HTC Vive spatial tracking data, developed by Jose Luis García del Castillo y López (@garciadelcast) at the Generative Design Group at Autodesk.

I just published #ViveTrack, an #opensource @DynamoBIM package for real-time #HTCVive tracking. Available for download from the pkg manager.

Facebook's homepage always offers you to, mainly, sign up and create a new account. But you only have to do that once. Every single time you access Facebook afterwards, you probably just want to log in. With the following steps, you'll be able to hide everything but the login form.

This workflow overrides the styling of some website elements to hide them, and you just need to paste the following code inside the Stylebot Chrome extension when you have Facebook.com open in your browser. It will just hide the HTML elements that clutter your screen and leave a clean interface for you to sign in.

#pagelet_video_home_suggested_for_you_rhc,
#createNav,
#appsNav,
#pageFooter,
.fb_logo,
.pvl,
.login_form_label_field {
    display: none;
}

How to install Stylebot (and apply this style to Facebook.com)

• Open this page on Google Chrome.
• Click on Add to Chrome.
• Go to Facebook.com
• Open Stylebot by clicking the CSS icon you just installed, in your browser's top-right panel.
• Then select Open Stylebot...
• Paste the code snippet in the text editor.
• Press Save.

Beware that, as Facebook updates their CSS class names (this is, the way the name the code that styles their website), this code will need to accommodate the user interface changes.

To import JSON into your TypeScript code, you need to add the following code to a typings file (a file with a name like *.d.ts, say, json.d.ts—but it does not necessarily need to say json)¹.

// This will allow you to load `.json` files from disk

declare module "*.json"
{ const value: any;
  export default value;
}

// This will allow you to load JSON from remote URL responses

declare module "json!*"
{ const value: any;
  export default value;
}

After doing this, you can do the following in TypeScript.

import * as graph from './data/graph.json';
import data from "json!http://foo.com/data_returns_json_response/";

You can then use graph and data as JSON objects in your TypeScript code.

I used this code to load a Dynamo JSON graph into TypeScript — just change the .dyn extension to .json and it will work with this code.
