--- layout: toplevelcontent title: Rust WebAssembly Hello World - Deep Dive with wasm-bindgen and wasm2wat description: Rust WebAssembly Hello World. keyword: rust webassembly, rustwasm hello world ---
In this article we are going to create a WebAssembly Hello World program with Rust. You might be thinking that a WebAssembly Hello World tutorial could be found almost everywhere, including one on Mozilla website and rustwasm.github.io. So why would you need to read this article?
This article is different as we are going beyond just getting the Hello World program to work. We will dig deeper to understand the codes generated by wasm-bindgen and how they all come together to help us with our development. The WebAssembly Binary Toolkit will also be used to explore the generated wasm code. This will give us a good understanding of Rust WebAssembly and a good foundation to start with. It also quickly becomes clear why Rust WebAssembly applications are smaller and more optimized as compared to other frameworks with Garbage Collector, and why it is a winner for developers with existing JavaScript web applications or websites. Things like web-sys (Raw API bindings for Web APIS) and WASI (WebAssembly System Interface) also become easier to appreciate.
{% include aa1.html %}
1. Install wasm-bindgen. There are other ways to create a Hello World program without wasm-bindgen. But in this tutorial, we are going to use it as it is essential in Rust WebAssembly development.
cargo install wasm-bindgen-cli
Rust WebAssembly enables you to surgically insert WebAssembly modules into your existing JavaScript applications, especially into your performance critical code paths. You can think of wasm-bindgen as a tool that helps you do that by generating the glue and bindings for the efficient interactions between JavaScript and WebAssembly.
2. Next, we will like to create a new Rust WebAssembly project. Enter the following command
cargo new helloworld --lib
You should see the following message. A new helloworld package with your project files has been created.
Created library `helloworld` package
3. Using a text editor, open Cargo.toml. You should see the following
[package]
name = "helloworld"
version = "0.1.0"
authors = ["djembe-waka "]
edition = "2018"
[dependencies]
Change it to the following:
[package]
name = "helloworld"
version = "0.1.0"
authors = ["djembe-waka "]
edition = "2018"
[lib]
crate-type = ["cdylib"]
[dependencies]
wasm-bindgen = "0.2"
The "cdylib" indicator makes this Rust project expose a C-style dynamic library that is used by linkers to produce our WebAssembly module. As described above, "wasm-bindgen" enables or facilitates high-level interactions between wasm modules and JavaScript.
4. Using a text editor, open "src/lib.rs". Change it to the following:
extern crate wasm_bindgen;
use wasm_bindgen::prelude::*;
// Import 'window.alert'
#[wasm_bindgen]
extern "C" {
fn alert(s: &str);
}
// Export a 'helloworld' function
#[wasm_bindgen]
pub fn helloworld(name: &str) {
alert(&format!("Hello World : {}!", name));
}
In the above code, "wasm_bindgen" allows us to import JavaScript things ('alert') into Rust and export Rust things ('helloworld') to JavaScript.
5. Compile the code. In your command line enter the following:
cargo build --target wasm32-unknown-unknown
If "wasm32-unknown-unknown target" is not installed, enter the following to install it.
rustup target add wasm32-unknown-unknown
6. Setup a web server to run our program.
We need a web server to test our WebAssembly "Hello World" program. We are going to use Webpack but you can also use another tool or web server that you are comfortable with. We need to create 3 files: index.js, package.json and webpack.config.js. However, we will not be going into the details of these files as we are going to focus on the codes generated by wasm-bindgen.
index.js
const rust = import('./pkg/helloworld');
rust
.then(m => m.helloworld('World!'))
.catch(console.error);
package.json
{
"scripts": {
"build": "webpack",
"serve": "webpack-dev-server"
},
"devDependencies": {
"@wasm-tool/wasm-pack-plugin": "0.4.2",
"text-encoding": "^0.7.0",
"html-webpack-plugin": "^3.2.0",
"webpack": "^4.29.4",
"webpack-cli": "^3.1.1",
"webpack-dev-server": "^3.1.0"
}
}
webpack.config.js
const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const webpack = require('webpack');
const WasmPackPlugin = require("@wasm-tool/wasm-pack-plugin");
module.exports = {
entry: './index.js',
output: {
path: path.resolve(__dirname, 'dist'),
filename: 'index.js',
},
plugins: [
new HtmlWebpackPlugin(),
new WasmPackPlugin({
crateDirectory: path.resolve(__dirname, ".")
}),
// Have this example work in Edge which doesn't ship `TextEncoder` or
// `TextDecoder` at this time.
new webpack.ProvidePlugin({
TextDecoder: ['text-encoding', 'TextDecoder'],
TextEncoder: ['text-encoding', 'TextEncoder']
})
],
mode: 'development'
};
You may require the following commands if some of the packages are not available on your system.
7. Build the program by running the following command:
npm run build
8. Run the Hello World program
npm run serve
Navigate your browser to "localhost:8080" and see a "Hello World!" alert being displayed.
8. Now that we got the Hello World program running, we want to dig deeper. Go to the "pkg" folder and see that the following files are automatically generated for you during the build process.
The files can also be generated manually by using the following wasm-bindgen cli command.
wasm-bindgen target/wasm32-unknown-unknown/debug/helloworld.wasm --out-dir ./pkg
9. The first thing we should do is to understand what happens when we run the Hello World program in a browser. The following shows the sequence of function calls (or more specifically the files containing the functions) that occur when we navigate point to "localhost:8080" in the browser.
index.js -> helloworld.js -> helloworld_bg.wasm
index.js
const rust = import('./pkg/helloworld');
rust
.then(m => m.helloworld('World!'))
.catch(console.error);
"index.js" imports a "helloworld.js" package and calls the "helloworld" function in the package.
helloworld.js
export function helloworld(name) {
const ptr0 = passStringToWasm(name);
const len0 = WASM_VECTOR_LEN;
try {
return wasm.helloworld(ptr0, len0);
} finally {
wasm.__wbindgen_free(ptr0, len0 * 1);
}
}
"helloworld.js" file is automatically generated by wasm-bindgen and contains the JavaScript glue for importing DOM and JavaScript functions into Rust. It also exposes an API on the generated WebAssembly functions to JavaScript.
Rust WebAssembly focuses on integrating WebAssembly with existing JavaScript applications. To do this, we need to pass different values, objects or structs from JavaScript in and out of WebAssembly functions. This is not easy as the different object types of two different systems need to be reconciled. To make matters worst, WebAssembly currently only supports integer and floating point numbers, not strings. This means you cannot simply pass a string into a WebAssembly function.
To pass a string into WebAssembly, you need to convert the string into numbers (note the TextEncoderAPI specified in webpack.config.js), put the numbers into the memory space of WebAssembly and finally return a pointer of the string to the WebAssembly function so that you can use it in JavaScript. At the end of it, you will need to free up the WebAssembly memory space used by the string.
If you look at the above JavaScript codes, this is exactly what has been executed automatically. The "helloworld" function first calls "passStringToWasm". This function creates some memory space in WebAssembly, converts your string to numbers, writes the numbers to the memory space, and returns a pointer to the string. The pointer is then passed to "wasm.helloworld" to perform your JavaScript "alert". Finally, "wasm.__wbindgen_free" frees up the memory. If you are just passing a simple string, you may be able to do this by yourself, but think of when you have more complex objects and structs, the effort quickly becomes non-trivial. This illustrates the importance of wasm-bindgen in Rust WebAssembly development.
10. In our previous step, we noted that a "helloworld.js" file is generated by wasm-bindgen, and the functions generated in this file call into our generated WebAssembly codes in "helloworld_bg.wasm". Basically, "helloworld.js" acts as a bridge between other JavaScripts such as index.js to the generated "helloworld_bg.wasm" WebAssembly.
We can explore "helloworld_bg.wasm" further by entering the following command:
wasm2wat helloworld_bg.wasm > helloworld.txt
This command uses the WebAssemblyBinary Toolkit to translate WebAssembly to WebAssembly text format and saves it to a "helloworld.txt" file. Open "helloworld.txt" in a text editor and look for the "$helloworld" function. This is the generated WebAssembly function of our "helloworld" function that we have defined in "src/lib.rs".
Look for the following line in "helloworld.txt":
(export "helloworld" (func $helloworld))
This line exports the "helloworld" wasm function for the host to call. We call this wasm function through "wasm.helloworld" in "helloworld.js".
Next, look for the following line:
(import "./helloworld.js" "__wbg_alert_7e2b9b91978b2246" (func $__wbg_alert_7e2b9b91978b2246 (type 2)))
This corresponds to the following JavaScript function generated in "helloworld.js"
export const __wbg_alert_7e2b9b91978b2246 = function(arg0, arg1)
This is the part where wasm-bindgen provides a glue to help you use JavaScript functions or the DOM in WebAssembly. With this, we now understand how wasm-bindgen helps us facilitate interaction by importing JavaScript things and exporting WebAssembly things.
11. Finally, let's take a look at the other files generated by wasm-bindgen.
"helloworld.d.ts"
This .d.ts file contains TypeScript type declarations for the JavaScript glue and is useful if your existing JavaScript application is using TypeScript. You can have your calls into WebAssembly functions type checked or have your IDE provide autocompletions. If you aren't using TypeScript, you can safely ignore this file.
"package.json"
The package.json file contains metadata about the generated JavaScript and WebAssembly package. It automatically fills in all the npm dependencies from your Rust code and enables you to publish to npm.
Take a look at the following code again:
helloworld.js
export function helloworld(name) {
const ptr0 = passStringToWasm(name);
const len0 = WASM_VECTOR_LEN;
try {
return wasm.helloworld(ptr0, len0);
} finally {
wasm.__wbindgen_free(ptr0, len0 * 1);
}
}
The code to allocate and deallocate the memory is carried out for you. There is no need for a Garbage Collector or a full framework engine making WebAssembly applications or modules written in Rust small and optimized. Other languages that require a Garbage Collector will need to include wasm code for their underlying framework engine. So, no matter how optimized they are, their size will not be smaller than what Rust provide. This makes Rust WebAssembly a good choice if you need to integrate or inject small WebAssembly modules into JavaScript web applications.
With wasm-bindgen, we can call a JavaScript function in Rust WebAssembly by using an "extern". Remember the following from "src/lib.rs":
#[wasm_bindgen]
extern "C" {
fn alert(s: &str);
}
The Web has a huge number of APIs, from DOM manipulation to WebGL to Web Audio. So if our Rust WebAssembly program grows, and we need to make many different calls to Web APIs, we will need to spend time writing a lot of "extern" code. web-sys serves to act as a frontend to wasm-bindgen to provide the raw bindings to all the Web's APIs. This means if you use web-sys, you can save time by not having to write the "extern" code.
This is a standardization effort to push WebAssembly beyond the browser. To run WebAssembly on a machine or OS (Operating System) outside the browser, we may need to access system resources. This standardization specifies how you can access these system resources in a secure and yet portable way across different machine architectures. Currently, there are already two implementations, Wasmtime by Mozilla, and Lucet by Fastly. And we need to ask ourselves, will WASM + WASI become the next Docker?


Trump tweets that he is 'strongly' considering testifying in impeachment hearings
Administration had said it would not cooperate
by Scripps NationalPresident Donald Trump tweeted Monday that he would "strongly consider" testifying in impeachment inquiry proceedings — either in writing or in person.
Trump's tweet came after House Speaker Nancy Pelosi suggested in a CBS "Face the Nation" interview Sunday that Trump testify.
"Our Crazy, Do Nothing (where's USMCA, infrastructure, lower drug pricing & much more?)  She also said I could do it in writing. Even though I did nothing wrong, and don't like giving credibility to this No Due Process Hoax, I like the idea & will, in order to get Congress focused again, strongly consider it!" Trump tweeted Monday.
Testimony by Trump would be an about-face for the administration, which has previously said it would not cooperate with the Democrat-led impeachment proceedings.
Public impeachment inquiry hearings will resume Tuesday, when Lt. Col. Alexander S. Vindman and Kurt D. Volker will appear before the House Intelligence Committee.

MapInfo TAB and MIF/MID
Driver short name
MapInfo File
Driver built-in by default
This driver is built-in by default
MapInfo datasets in native (TAB) format and in interchange (MIF/MID) format are supported for reading and writing. Update of existing TAB files is supported (append of new features, modifications and deletions of existing features, adding/renaming/deleting fields, ...). Update of existing MIF/MID files is not supported.
Note: In the rest of this document "MIF/MID File" is used to refer to a pair of .MIF + .MID files, and "TAB file" refers to the set of files for a MapInfo table in binary form (usually with extensions .TAB, .DAT, .MAP, .ID, .IND).
The MapInfo driver treats a whole directory of files as a dataset, and a single file within that directory as a layer. In this case the directory name should be used as the dataset name.
However, it is also possible to use one of the files (.tab or .mif) in a MapInfo set as the dataset name, and then it will be treated as a dataset with one single layer.
MapInfo coordinate system information is supported for reading and writing.
Driver capabilities
Supports Create()
This driver supports the GDALDriver::Create()
operation
Supports Georeferencing
This driver supports georeferencing
Supports VirtualIO
This driver supports virtual I/O operations (/vsimem/, etc.)
Creation Issues
The TAB File format requires that the bounds (geographical extents) of a new file be set before writing the first feature.
There is currently no automated setting of valid default bounds for each spatial reference system, so for the time being, the MapInfo driver sets the following default bounds when a new layer is created:
For a file in LAT/LON (geographic) coordinates: BOUNDS (-180, -90) (180, 90)
For any other projection: BOUNDS (-30000000 + false_easting, -15000000 + false_northing) (30000000 + false_easting, 15000000 + false_northing)
It is possible to override those bounds through two mechanisms.
specify a user-defined file that contain projection definitions with bounds. The name of this file must be specified with the
MITAB_BOUNDS_FILE
configuration option. This allows users to override the default bounds for existing projections, and to define bounds for new projections not listed in the hard-coded table in the driver. The format of the file is a simple text file with one CoordSys string per line. The CoordSys lines should follow the MIF specs, and MUST include the optional Bounds definition at the end of the line, e.g.# Lambert 93 French bounds CoordSys Earth Projection 3, 33, "m", 3, 46.5, 44, 49.00000000002, 700000, 6600000 Bounds (75000, 6000000) (1275000, 7200000)
It is also possible to establish a mapping between a source CoordSys and a target CoordSys with bounds. Such a mapping is specified by adding a line starting with "Source = " followed by a CoordSys (spaces before or after the equal sign do not matter). The following line should start with "Destination = " followed by a CoordSys with bounds, e.g.
# Map generic Lambert 93 to French Lambert 93, Europe bounds Source = CoordSys Earth Projection 3, 33, "m", 3, 46.5, 44, 49, 700000, 6600000 Destination = CoordSys Earth Projection 3, 33, "m", 3, 46.5, 44, 49.00000000001, 700000, 6600000 Bounds (-792421, 5278231) (3520778, 9741029)
use the
BOUNDS
layer creation option (see below)
If no coordinate system is provided when creating a layer, the projection case is used, not geographic, which can result in very low precision if the coordinates really are geographic. You can add "-a_srs WGS84" to the ogr2ogr commandline during a translation to force geographic mode.
MapInfo feature attributes suffer a number of limitations:
Only Integer, Real and String field types can be created. The various list, and binary field types cannot be created.
For String fields, the field width is used to establish storage size in the .dat file. This means that strings longer than the field width will be truncated
String fields without an assigned width are treated as 254 characters.
Dataset Creation Options
FORMAT=[TAB/MIF]: To create MIF/MID instead of TAB files
SPATIAL_INDEX_MODE=[QUICK/OPTIMIZED]: Defaults to
QUICK
. In QUICK mode writing files can be about 5 times faster, but spatial queries can be up to 30 times slower. This can be set to OPTIMIZED to generate optimized spatial index.BLOCKSIZE=[512/1024/.../32256]: Defaults to
512
. (multiples of 512) Block size for .map files. MapInfo 15.2 and above creates .tab files with a blocksize of 16384 bytes. Any MapInfo version should be able to handle block sizes from 512 to 32256.
Layer Creation Options
BOUNDS=<xmin,ymin,xmax,ymax>: Define custom layer bounds to increase the accuracy of the coordinates. Note: the geometry of written features must be within the defined box.
ENCODING=value: Define the encoding for field names and field values. The encoding name is specified in the format supported by
CPLRecode()
(e.g. ISO-8859-1, CP1251, CP1252 ...) and internally converted to MapInfo charsets names. Default value is '' that equals to 'Neutral' MapInfo charset.DESCRIPTION=value: (GDAL >= 3.1.0) Friendly layer name (only for TAB format). Friendly names can be up to 256 characters long and can include most ASCII characters. Supported by MapInfo Pro v15.0 or higher.
Configuration options
The following configuration options are available:
MITAB_BOUNDS_FILE=value: See Creation Issues.
MITAB_SET_TOWGS84_ON_KNOWN_DATUM=[YES/NO]: (GDAL >= 3.0.3) The default behavior, starting with GDAL 3.0.3, is NO. That is, the TOWGS84 parameters read from the .tab header will not be set on the Datum object of the CRS, when the datum can be inferred.

Smoke Shrouds Sydney’s Skyline As Wildfires Burn Nearby
by Associated Press Television NewsRest of the World News
Smoke haze covers Sydney, Tuesday, Nov. 19, 2019, as wildfires burn near the city.
Written By Associated Press Television News | Mumbai | Updated On: November 19, 2019 10:29 IST
Smoke haze covers Sydney, Tuesday, Nov. 19, 2019, as wildfires burn near the city. The annual Australian fire season, which peaks during the Southern Hemisphere summer, has started early after an unusually warm and dry winter.
Thick smoke from wildfires has shrouded Sydney and its surrounding areas with health experts warning residents with medical conditions to remain indoors.
The Sydney skyline was barely visible with air quality in some parts of the city reaching over hazardous levels early Tuesday.
Shane Fitzsimmons, the state’s rural fire commissioner, says firefighters would be challenged by high temperatures and wind conditions.
Most of the coastal areas of the New South Wales are under very high fire danger with 48 fires burning across the state.
Fires have destroyed 577 homes in New South Wales during the wildfire season, which peaks during the Southern Hemisphere summer but has started early after an unusually warm and dry winter.


6 LTO offices collect billion-peso fees
by Jun I. LegaspiTHE Department of Transportation–Land Transportation Office (DOTr-LTO) yesterday announced the top six regional offices which have exceeded the billion (B)-peso mark in revenue collection as of October 31, 2019.
Topping the list is National Capital Region (NCR)-East with P3.06B. It is followed by National Capital Region-West with P2.7B; Regional Office 3 with P2.68 billion; Regional Office 4-A, P2.65B; Regional Office 7, P1.6B; and Regional Office 6 with P1.2B.
“We are glad to announce that several LTO regional offices have already pegged their collection beyond the billion-peso mark this October,” LTO Assistant Secretary Edgar C. Galvante said.
The LTO Chief noted that the regional offices have been instituting reforms in their respective offices which resulted in more efficient revenue collection.
“The LTO is serious in its effort to ensure accurate reporting and remittance of revenue collections,” Galvante said.
“We will continue the adoption of technology-driven measures to make the flow of LTO transactions more systematic, user-friendly, convenient, accessible and effective, especially in terms of revenue collection,” Galvante assured.


What the papers say – November 24
Spending pledges and other election promises lead many of Sunday’s front pages.
Previews of the Conservative Party’s election manifesto dominate the Sunday newspapers.
The Sunday Telegraph centres on a Tory plan to axe hospital car parking fees for millions of people.
The Sunday Times reports on Prime Minister Boris Johnson’s pledge not to raise personal taxes.
And the Sunday Express calls the manifesto, which will be released on Sunday, Mr Johnson’s “big Christmas gift to Britain”.
The Observer also features Mr Johnson’s tax plans on its front page, but leads with a major funding pledge from the Labour Party to help women caught in a pension trap.
The Sunday Mirror carries the same pension story, along with an account of another woman who has made claims of an association with the Duke of York.
And The Independent says the Lib Dems are aiming to defeat some major figures of the Brexit debate at the election, such as Dominic Raab.
Meanwhile, The Mail on Sunday leads on former MI6 chief Richard Dearlove saying Jeremy Corbyn would be a danger to national security if elected prime minister.
The Sunday People reports on a knife factory allegedly being run inside a prison.
And the Daily Star Sunday leads on a soap star’s dash to hospital after her dog scratched her eye.

Landsat Planet Comparisons
Comparing Landsat and PlanetScope Scenes¶
A common and powerful workflow for analysis is comparing or combining information from multiple sources. This tutorial demonstrates comparing a set of Landsat and PlanetScope scenes.
In this tutorial, we download scenes from the two sensors taken on the same day at the same place, visualize them, resample the Landsat scene to match the pixel resolution and locations of the PlanetScope scene, and perform pixel-by-pixel comparison of their near-infrared (NIR) bands.
Our comparison of the NIR bands is identification of the difference between the scaled NIR bands. We find that most differences between the NIR bands are at high-resolution features and are due to the lower resolution of the Landsat scene. However, we also find a few fields show noticeable difference in the NIR bands. We theorize that these differences may be due to the different spectral responses of the two sensors and the fields containing different crop types than the surrounding fields. These results suggest that an analysis utilizing both Landsat8 and PlanetScope scenes may be able to better differentiate crop types than just using one sensor.
Ideas for extending beyond this notebook: 1. Mask the scenes using the PlanetScope Unusable Data Mask and Landsat Quality Assurance bands 2. Convert the PlanetScope scene to reflectance and then do not normalize the bands in the difference calculation
Install Dependencies and Set up Notebook¶
import os import shutil from subprocess import check_output, STDOUT, CalledProcessError from six.moves import urllib import numpy as np import rasterio import rasterio.enums import rasterio.vrt import requests %matplotlib inline
Download Scenes¶
In the crossovers notebook, we identified many Landsat/PlanetScope crossovers within the same day that occured between January and August 2017. From that list, we are going to download the following set of scenes: - PSOrthoTile 644787_1056721_2017-07-25_0f52 - Landsat8L1G LC80430332017206LGN00
| PSOrthoTile | Landsat8L1G |
|---|---|
These scenes represent a crossover between Landsat8 and PlanetScope on July 25, 2017.
For the Landsat8L1G scene, we download band 5, which is the NIR band (ref).
To download the scenes, we use the planet CLI because it handles activating, waiting for activation, and downloading the file.
We will save the scenes in the data
folder. This folder isn't tracked by git so the downloaded image file will not bloat our git repository.
Download PlanetScope Orthotile Scene¶
# Create a working directory if it does not already exist. data_folder = 'data' if not os.path.isdir(data_folder): os.mkdir(data_folder)
# First test if scene file exists, if not, use the Planet commandline tool to download the image. # This command assumes a bash shell, available in Unix-based operating systems. !test -f data/644787_1056721_2017-07-25_0f52_BGRN_Analytic.tif || \ planet data download \ --item-type PSOrthoTile \ --asset-type analytic \ --string-in id 644787_1056721_2017-07-25_0f52 \ --dest data
# Store the image filename for processing and make sure the file exists. pl_filename = os.path.join('data', '644787_1056721_2017-07-25_0f52_BGRN_Analytic.tif') print(pl_filename) assert os.path.isfile(pl_filename)
../data/644787_1056721_2017-07-25_0f52_BGRN_Analytic.tif
Download Landsat NIR Band¶
Landsat is distributed with each asset as an individual band. Band 5 is the NIR band. Since we only plan on using the NIR band, we will download just that asset.
NOTE: The command below should work, but currently there is a bug in the planet CLI. Until that is fixed, use the curl command to download the asset from the endpoint directly.
# !planet data download \ # --item-type Landsat8L1G \ # --asset-type analytic_b5 \ # --string-in id LC80430332017206LGN00 \ # --dest data/ # !ls -l --block-size=M data/
# The long way of downloading an asset. Doesn't use the planet CLI def get_auth(): auth = (os.environ['PL_API_KEY'], '') return auth def get_asset_info(asset): auth = get_auth() item_assets_url = 'https://api.planet.com/data/v1/item-types/Landsat8L1G/items/LC80430332017206LGN00/assets/' r = requests.get(item_assets_url, auth=auth) assert r.status_code == 200 assets_resp = r.json() return assets_resp[asset] def activate(asset): asset_info = get_asset_info(asset) activation_link = asset_info['_links']['activate'] auth = get_auth() r = requests.post(activation_link, auth=auth) assert r.status_code == 204 def download(asset, path): if not os.path.isfile(path): asset_info = get_asset_info(asset) download_link = asset_info['location'] urllib.request.urlretrieve(download_link, path) asset = 'analytic_b5' activate(asset) # it may take a while for the asset to be activated. If this fails, wait a while and rerun landsat_filename = os.path.join('data', 'LC80430332017206LGN00_{}.tif'.format(asset)) download(asset, landsat_filename)
# store the Landsat band filename for processing and make sure the file exists l8_nir_orig_filename = os.path.join('data', 'LC80430332017206LGN00_analytic_b5.tif') print(l8_nir_orig_filename) assert os.path.isfile(l8_nir_orig_filename)
../data/LC80430332017206LGN00_analytic_b5.tif
Warp Landsat Scene to Planet Scene¶
For pixel-by-pixel comparison of the Landsat and Planet scenes, the two scenes must have the same extents, the pixels must be the same size, and the pixels must exactly overlap each other. This can all be achieved by warping one scene to the other scene. We warp the Landsat scene to the Planet scene because the Planet scene is much higher resolution than the Landsat scene and we want to use the highest resolution possible for our comparison.
The GDAL command-line interface, specifically gdalwarp, is the easiest way to warp one image to another image.
def prepare_l8_band(band_filename, dst_filename, out_filename): """Project, crop, and resample landsat 8 band to match dst_filename image.""" # Open the Landsat8 band file. with rasterio.open(band_filename) as src: # Open the Planet image to use as a template. with rasterio.open(dst_filename) as pl: # A Virtual Raster (VRT) allows for describing raster transformations and delaying computation # until data is accessed. The WarpedVRT() class describes how to warp a dataset, but the # reprojection calculations are not transformed, and they are only transformed # These parameters define a target image in the same coordinate reference system as the # PlanetScope image and the same number of rows and columns. warp_params = { 'crs': pl.crs, 'transform': pl.transform, 'width': pl.width, 'height': pl.height } with rasterio.vrt.WarpedVRT(src, **warp_params) as vrt: # Using the PlanetScope image as a reference, create an output. The PlanetScope image # has 4 bands but the Landsat 8 image only has 1. Update the output image profile with # this information. out_profile = pl.profile.copy() out_profile['count'] = vrt.count with rasterio.open(out_filename, 'w', **out_profile) as dst: # This 'vrt.read()' triggers the warp calculations. data = vrt.read() # Write data to output file. dst.write(data) l8_nir_filename = os.path.join('data', 'LC80430332017206LGN00_analytic_b5_warped.tif') prepare_l8_band(l8_nir_orig_filename, pl_filename, l8_nir_filename)
Load and Visualize NIR Bands¶
Before moving on to comparing the NIR bands, we load the NIR bands from each scene and visualize the bands.
Instead of including a huge chunk of code for visualizing the NIR band, we put that code in a local script (visual.py) and import here.
Ideally, we would use the PlanetScope Unusable Data Mask (UDM) and Landsat Quality Assurance (QA) bands to create the pixel masks. In the interest of keeping this tutorial focused, we perform a simple and brute-force masking where we mask pixels that are equal to the blackfill NoData value, 0.
import visual
# Display Landsat 8 NIR band. with rasterio.open(l8_nir_filename, 'r') as src: data = src.read(1) # Generate a masked array with a mask representing 0 pixels. mask = data == 0 l8_nir_band = np.ma.array(data, mask=mask) visual.plot_image(l8_nir_band, title='Landsat8 NIR')
# Display PlanetScope NIR band. with rasterio.open(pl_filename, 'r') as src: data = src.read(3) mask = data == 0 pl_nir_band = np.ma.array(data, mask=mask) visual.plot_image(pl_nir_band, title='PSOrthotile NIR')
Compare NIR Bands¶
In this section we look at the difference in response between the NIR bands of the two sensors.
The difference is calculated as the absolute value of the subtraction of one normalized NIR band from the other normalized NIR band.
Note: Landsat8 is corrected to reflectance and PlanetScope is corrected to radiance. The conversion between reflectance and radiance is achieved by scaling the entire band. In this comparison, we normalize the two NIR bands to 0-1 anyway, so the radiance/reflectance difference doesn't affect us.
def rescale(ndarray, old_min=None, old_max=None, new_min=0, new_max=1): if old_min is None: old_min = ndarray.min() if old_max is None: old_max = ndarray.max() # https://en.wikipedia.org/wiki/Normalization_(image_processing) return (ndarray.astype(np.float) - old_min) * (new_max - new_min) / (old_max - old_min) + new_min
# Scale the bands so that the maximum value is 1 diff_band = abs(rescale(l8_nir_band, old_min=0) - rescale(pl_nir_band, old_min=0)) # Mask a pixel in the difference band if it is masked in either the Landsat 8 or PlanetScope data. diff_band.mask = l8_nir_band.mask | pl_nir_band.mask
visual.plot_image(diff_band)
In general, the major differences between the NIR bands occur at high-resolution features (edges of fields, roads, and populated areas) and are caused by the lower resolution of the Landsat8 sensor. However, there are a few larger regions, which appear to be fields, that show some difference between the NIR bands.
Lets zoom into one such region, the square field located just right of center of the image.
region = (np.s_[3000:5000], np.s_[3500:5500]) # create a (rows, columns) numpy slice for indexing the array figsize = (5, 5) visual.plot_image(diff_band[region], title='NIR Difference', figsize=figsize) visual.plot_image(pl_nir_band[region], title='PlanetScope NIR', figsize=figsize) visual.plot_image(l8_nir_band[region], title='Landsat8 NIR', figsize=figsize)
Interestingly, it appears the square field which pops out in the difference image is less differentiated from the surrounding fields in the Landsat scene than in the PlanetScope scene. Since both scenes were collected on the same day, this is likely due to a different in the spectral responses of the NIR bands for the two sensors combined with the crop type of that field. The center wavelength of the NIR response for the PlanetScope sensor is 825nm, while it is 865nm for the Landsat sensor. This shows that an analysis utilizing both Landsat8 and PlanetScope scenes may be able to better differentiate crop types. There is great potential in combining scenes from multiple sensors for analysis.

On Wednesday February 16th, I did a presentation at Malmö Högskola on the topic of HTML5, CSS3 and Phonegap. Most attendees were students from the cool education "Media production and process design". Some of these students are going to be doing some hands-on web development in the future, but I am sure that almost all are going to be involved in web and mobile web strategies at some point. I tried to find a good balance between tech talk and mobile web strategies like progressive enhancement, graceful degradation, feature and cost comparison between native apps and Phonegap apps.

Linux Python diskspace script
Posted on Sun 20 May 2018 in python
Monitoring diskspace using Python
Below is a script to monitor output from Linux df -h command. I use a cronjob that runs every 2 minutes to ammend df -h output to a text file then use this script to sort through that data.
This could be done much easier in bash but the point was to practice Python. There is also the future plan to use HTTP POST requests to send this data to a web UI.

Four men rob east side business, police say
by Logan RudeMADISON, Wis. - Four masked men robbed an east side business Wednesday morning after they ordered an employee to let them inside the building, according to an incident report.
Police said the employee arrived at PL$ Check Cashing on E. Washington Avenue to open the business when four masked men approached her. According to the incident report, at least one of them had a gun. The woman let the men inside, and they stole money from the safe, police said.
The victim said the robbers were all black males in their teens wearing mostly dark clothing, hoodies and masks, according to the report.

Hi, you can call me Spit and I had a big acne problem in the year 2000 and I tried a lot of different pills to get rid of it with no success until one day I heard about Acutane and I ask my dermatologist to try it. He prescribed me 1 pill each day for 4 months and after 2 pills each day for another 4 months (which includes 4 blood test to see if I am developing diabete or I don't know what).
Well I heard a lot of things about this med. like it can cause depression and lots of physical and/or mental problems but at that time I had nothing to loose because I was scary to look at and well if I didn`t get rid of that acne, I felt like I could go into a depression at any moment and who knows, suicide myself (it was that bad, I still have pictures to prove it!!). So if you didn't guessed it, I took them :) . So here`s a summary of the good/side effects I got.
First Month: Everything is cool.....wow only after 3 weeks 10% of my acne is gone !!! This is a miracle, (no side effects yet)
Second Month: Heh I like it, what i`m smiling !! life is beautiful but for some reason my nose is bleeding once a week and god my lips are so dry !! Blistex is my new friend.
Third Month: Well 30% of it is gone... i`m happy and I had an annual checkup with my doc. well he found my blood pressure is a little too high and when he saw my skin he knew I was on Accutane..(heh....so dry it`s like a raindrop of dandruff when I scratch it).
Fourth Month: My skin is so much different but I don`t know... I feel like something is not normal... my lips are cracking and sometimes it bleeds... my eyes are so dry, I need something to wet them. I`m a little scared to jump at 2x. daily for 4 months but anyway i`ll do it.
Fifth Month: I don`t know why but I got a backache for no reason and it doesn`t leave me... i`m a little scared but sometimes I forget about it and i`m a little less happier than usual.
Six Month: Now I like what I saw in the mirror, i mean wow there`s not much left, all my friends says that i`m more handsome ..anyway.
Still have my backpain and all the side effects but 2x. worse (i mean it... really).
Seven Month: Well ok that hurts (my back) and I don`t know... something is not quite right when it`s dark I can`t see a thing... well it`s like worse than usual and god i`m tired of taking them I want to party !!! My mood is swinging (that`s what my mother thought..not me).
Eight Month: At last i`m done and now my skin is looking almost like a normal person and scars are almost all gone... (how a med. can do this... i still don`t know) no more new side effects.
Now, it`s been 2 years since I stopped taking them and it took approx. 6 months for the backpain to go away and 1 year to see my lips normal again.. (they was pretty messed up) and 4 months ago I recovered of all that mood swings, little depression. It was the hardest 8 months of my life to live but I don`t regret my choice and recently, yesterday (11 sep. 2002, God Bless America) I will take them for 2 months at 2x pill daily just to regulate my system because I still see some left (really, really not much) and I want to get rid of it for good !!

I understand some suicide themselves while on the med. but for some it works and for others well please stop them before it`s too late (it may be the pills !!).
And I don`t think alcohol mix well with them and for me cannabis didn`t (that`s another story ;) ).
So if nothing works and you`re desesperate take them but be careful!!
Wow thanks for reading me... I think this report is long enough now.. Cya :)

rtc-videoproc
This is a small helper module that allows you to substitute a video element with a canvas element. This can be useful when you want to do pixel manipulation of the rendered images, or in situations when a video element does not behave as you expect.
Example Usage
var crel = require('crel');
var videoproc = require('rtc-videoproc');
var video = crel('video', { src: '../test/assets/tennis.webm', autoplay: true });
var canvas = crel('canvas');
var processor = videoproc(video, canvas, {
filter: require('rtc-filter-grayscale')
});
document.body.appendChild(canvas);
Using the Processing Pipeline
A processing pipeline has been included to assist with
manipulating the canvas on the fly. To specify the filters to be used
in the processing pipeline, this is done in the options accepted by
videoproc. Either specifying an array of filters with the filters
option
or a single filter function with the filter
option is fine. If you use
both then the individual filter will be added filter list and used in
series.
videoproc(srcVideo, targetCanvas, {
filters: [
require('rtc-filter-grayscale'),
myCustomFilterFunction
]
});
Writing a Filter Function
Writing a filter function is very simple, and they use the following function signature:
function filter(imageData, tick) {
}
The imageData
arg is an
ImageData, and the tick
argument refers to the tick that has been captured as part of the capture
loop (be aware that it could be a high resolution timer value if rAF is
being used).
If you are writing an analysis filter, then simply do what you need to do
and exit the function. If you have written a filter that modifies the pixel
data and you want this drawn back to the canvas then your filter must
return true
to tell rtc-videoproc
that it should draw the imageData
back to the canvas.
Listening for custom frame
events
In addition to providing the opportunity to analyse and modify pixel data
the rtc-videoproc
module also provides the a custom frame
event for
detecting when a new frame has been drawn to the canvas.
A simple example can be found below:
var videoproc = require('rtc-videoproc');
var crel = require('crel');
var video = crel('video', { src: '../test/assets/tennis.webm', autoplay: true });
// set up the video processing pipeline
videoproc(video).on('frame', function(tick) {
console.log('captured frame at: ' + tick);
});
// add the canvas to the dom
document.body.appendChild(video);
NOTE: The frame
event occurs after the filter pipeline has been run and
and the imageData may have been modified from the original video frame.
A Note with Regards to CPU Usage
By default rtc-videoproc will draw at 25fps but this can be modified to capture at a lower frame rate for slower devices, or increased if you have a machine with plenty of grunt.
Reference
videoproc(src, target, opts?)
Create (or patch) a <canvas>
element that will receive the video images
from a video element. The following options are supported.
canvas
- the canvas to draw video data to. If not supplied a new canvas element will be created.video
- the video element that will be used as the source of the video. If not supplied a new<video>
element will be created.fps
- the redraw rate of the fake video (default = 25)greedy
- Specifygreedy: true
if you want the videoproc module to run it's capture loop using setTimeout rather thanrequestAnimationFrame
. Doing this will mean you application will continue to capture and process frames even when it's tab / window becomes inactive. This is usually the desired behaviour with video conferencing applications.

Extraction2Extracting ML from Coq, Part 2
(* $Date: 2012-05-03 17:52:38 -0400 (Thu, 03 May 2012) $ *)
Let's take a look at a slightly fancier way of using Coq's
extraction facilities. Instead of translating a functional
program in Coq into a functional program in OCaml, we'll extract
the computational content of an interesting proof — the proof
that the STLC is normalizing. The result will be an evaluator
that takes well-typed STLC terms to their final normal forms.
Note that this is a slightly unusual way of using Coq. In the
words of Adam Chlipala...
Many fans of the Curry-Howard correspondence support the idea of
extracting programs from proofs. In reality, few users of Coq and
related tools do any such thing. Instead, extraction is better
thought of as an optimization that reduces the runtime costs of
expressive typing. (Chlipala, CPDT)
However, it's interesting to see that it's possible at all! (And
to think about what the extracted program does.)
Extracting a Normalizer
Require Import Extraction.
Require Import NormInType.
The NormInType module is a variant of the Norm module with a
few significant differences. The essential point is that, during
extraction, everything to do with Prop is erased. So, to
extract a normalizer from a proof of normalization, we need to
carry out the essential bits of the normalization proof in Type
rather than Prop.
NormInType also incorporates a copy of the STLC typechecking
function from the Typechecking module and its proof of
correctness. (The function itself is no different from before,
and the correctness proof has just a few small differences because
of the changes we made to the basic definitions of STLC.) We need
these things because the proof of normalization proceeds by
induction on a typing derivation, so the extracted normalization
function must be passed a data structure representing a typing
derivation. In normdriver.ml, we obtain this derivation from
the proof that the typechecking algorithm is sound.
Extraction "norm.ml" normalization type_check type_checking_sound.
Take a look at normdriver.ml to see how this plumbing works in
detail.
Finally, we can compile and execute our normalizer in the same way
as we did with our evaluator for Imp.
ocamlc -w -20 -o normdriver norm.mli norm.ml normdriver.ml ./normdriver


learning
People perform this or that kind of learning throughout their lives for all sorts of reasons. To keep up with their interests, maintaining social relationships, navigating the daily routines of their lives, etc. Learning in this sense is as quotidian an activity as dining and people engage in this activity in intricate ways, either by the nature of their jobs (so called knowledge workers) or simply their own curiosity. There are several ways that people approach learning, such as the unstructured learning that occurs over considerable time intervals across multiple domains, startegic skill making through apprenticeship, or self-learning. Regardless of the approach you use or the goal you want to achieve, there should be general principles, approaches, and strategies that one can use that can reduce the anxiety and risk involved in learning
spaced repetition
You can leverage the Spacing Effect
phenomenon as a
technique to learn things that you know are of value to your future self
Reasoning behind the practise
There are several interesting articles on the internet such as the Literature Review and Techniques from Gwern, Mullen on Memory Study Hacks, and Michael Nielsen on Augmenting Long-Term Memory
Strategy and Technique
Learn research papers, textbooks, and the like by making Anki notes on top of notes/work produced while learning the Technical Material. A model for the same in mathematics is described by Michael Nielsen in SR for Maths
theory of learning
MOOC offered by Barbara Oakley and Terrence Sejnowski Learning how to Learn provides some interesting terms such as chunking
Why books don't work by Andy Matushak recommends readers to learn specific reflective strategies (metacognition) such as asking "How should I summarise what I'm reading?"
Core Ideas
- The 2 primary modes of thinking are focused & diffused
- Concepts, ideas have associations, hierarchies, and usually come together in chunks (relate to networks of neurons)
- Conceptual chunks related to each other through Meaning
- Working memory maybe 4-Sloted & scratchpad like
- Long term memory may be clunk & warehouse like
- Meta cognition can change cognition
Behavioural Ideas
- Sleep is really important to long term memory formation
- You can learn by doing → Active Engagement
- Exercise can invoke thinking paths, environment can register memories (like in the memory palace technique) → Embodied Cognition
- Focused practise and repetition over time builds understanding
Note: hard to vary explanations missing for some of these ideas
Memory Palaces & Ancient Techniques
Embodied Cognition running on Ancient Memory Architectures
Lynne Kelly lists different ways that ancient cultures could have used rituals, landscapes, man-made structures, and other extended cognition tools to serve as cultural memory before the time of the written record. She also talks about philosophy expressed in (popular) music as knowledge tools of culture in Lynne’s conversation with Sean Carrol

The first Web Host I researched was Bluehost.com.
Bluehost's starting cost is $2.95 per month, and renews at $7.99 per month. Bigger plans are normally $14.99, such as Choice Plus. The biggest plan you can buy is Pro, which is normally $23.99 a month. All plans come with a free domain name for the first year. Bluehost is known for being simple and user friendly, making it a good choice for beginners.
The second Web Host I researched was Godaddy.com.
Godaddy has four different plans that you can choose from. These plans range from $8.99 to $24.99 . ALl of these plans include 24/7 security monitoring, a free domain name, and 125+ free applications. Godaddy has good credibility and is well known. You can be a beginner with Godaddy, as well as having multiple complex sites. Godaddy supports all users.
The third Web Host I researched was ipage.com.
Ipage is normally $7.99 a month, making it around the same price as the other ones I researched. I did not see other plans that you could purchase for other prices. They offer a 30-day money back guarantee, as well as a free domain name for a year. They also offer free ad credit for search engines. While you can host unlimited domains within your account, there is also PayPal integration with unlimited disk space.
The Web Hosting site that I felt was most appealing was the GoDaddy one. I am a big believer in going with companies that have credidibilty towards their names. I need to know that the company I use to host my website is going to be one that I can trust. I also like how they offer 24/7 security monitoring for all plans, not just the more expensive ones. This shows they care about their customers.

Vertcoin Core integration/staging tree
What is Vertcoin?
Vertcoin is a fork of Bitcoin that is designed to resist the monopolisation of mining power.
- 2.5 minute block targets
- subsidy halves in 840k blocks (~4 years)
- ~84 million total coins
- 50 coins per block (25 after block 840,000)
- Difficulty retargeting every block to recover from large hashrate swings
- Lyra2REv2 proof of work algorithm for ASIC resistance
For more information, as well as an immediately useable, binary version of the Vertcoin client sofware, see http://www.vertcoin.org.
License
Vertcoin Core is released under the terms of the MIT license. See COPYING for more information or see https://opensource.org/licenses/MIT.
Development Process
The master
branch is regularly built and tested, but is not guaranteed to be
completely stable. Tags are created
regularly to indicate new official, stable release versions of Vertcoin Core.
Developers work on their own forks and submit pull requests in order to merge
changes with master
. Due to the relatively small size of the development team,
developers also commit directly to the repo often. Anyone is allowed to contribute
though and useful pull requests will almost always be accepted given various
obvious stipulations regarding stability etc.
The Vertcoin discord or subreddit should be used to discuss complicated or controversial changes with the developers before working on a patch set.
Testing
Vertcoin currently relies on Bitcoin Core for its testcases, and few of them are known to work, though the software is based on fully test conforming upstream Bitcoin Core versions. We would be grateful to those who can help port the existing Bitcoin Core test cases to Vertcoin such that they can be used to assure correctness.
Translations
Changes to translations as well as new translations can be submitted to as pull requests to this repo or to upstream Bitcoin Core.

 Have you tried to pick up the local slang? Then you might just be a 'culture vulture'...
by Joseph Wilkes, Astrid Hall, https://www.facebook.com/dailymirror/Picking eateries which are bustling with locals, learning regional slang and getting annoyed by other tourists are among the signs you are a 'Culture Vulture'.
Learning the etiquette of the region, doing a walking tour of the city with a resident guide and avoiding tourist traps to scout out hidden gems also top the list of the avid globetrotter.
Other signs include trying the local cuisine, checking for festivals taking place during your visit, being able to travel alone, owning multiple guidebooks and wearing clothing of the region you're visiting.
The study of 2,000 Brits also found that 84 per cent would describe themselves as a 'culture vulture', and eight in 10 enjoy visiting locations which are off the beaten track.
Florian Sengstschmid, CEO for the Azerbaijan Tourism Board, said: "It's good to get out of your comfort zone and explore new and lesser known destinations.
"Going off the beaten track, asking locals for tips and just exploring things you wouldn't normally do are great ways to really enjoy a location and make the most of it.
"It's great to see how many Brits are keen to explore new sights and leave no stone unturned when travelling to new and exciting locations."
It also emerged seven in 10 adults reckon they are the adventurous type and 87 per cent will try something new when they travel abroad.
Nearly half of those polled will always visit the most famous sights or landmarks when travelling somewhere unfamiliar.
But a fifth prefer to take a trip to the lesser known places on the map when visiting somewhere new, as nearly a third are more likely to enjoy a holiday if they feel no one else has been there.
In fact, three in 10 even said they will visit strange or unheard-of places just to post about them on their social feeds.
Being a culture vulture isn't all that beneficial for these social media nomads though, as a quarter reckon you'll get more likes on a post of familiar locations over the more obscure.
Two fifths of those polled, via OnePoll, prefer natural wonders over man-made marvels when travelling.
And in a bid to see and experience more, eight in 10 will usually try and book a new destination they've never visited when scoping out a holiday.
Around three in 10 also intend to visit a brand-new location during the next vacation they have planned.
It also emerged nearly a quarter reckon they are the bigger culture vulture compared to their partner.
And more than a third admitted their passion for travel can create rifts between themselves and their other half.
Florian Sengstschmid added: "It can be nerve-wrecking going somewhere unfamiliar as our study found language barriers and the unfamiliar can be something that puts people off new experiences.
"However; our research also found more than a third have never visited Azerbaijan but would like to, and it is truly an exciting and unique place to visit."

12. Always carrying the right currency wherever you are
13. Doing a walking tour of the city with a local guide
14. Watching documentaries on the country you are visiting before travelling
15. Knowing about the art of a country
16. Buying local art to return home with
17. Going somewhere nobody else has been
