options override env variables, which overrides file based config.\n\n\n\nCurrently the following values may be specified\n\n\n\n* `http_port` The HTTP port to bind to, defaults to 10080\n\n* `ws_port` The port the websocket listens on, defaults to 10081\n\n* `bind_address` The ip address the server binds to, defaults to 127.0.0.1 ( localhost )\n\n\n\nWhen wsss starts, it first tries to load configuration information from the following files: \n\n\n\n1. The file specified by the environment variable `WSS_CONF_FILE`\n\n1. It then tries to load the file in `/etc/wsss/wsss_conf.toml`\n\n1. It then tries to load a `wsss_conf.toml` file located in the same directory as the wsss executable\n\n\n\nOnly the first file found is loaded.\n\n\n\nThe configuration file makes use of [TOML](https://github.com/toml-lang/toml). Here is a sample config:\n\n\n\n``` toml\n\n# Sample config. Hashes mark comments\n\n\n\nhttp_port = 10090\n\nws_port = 10095\n\nbind_address = \"10.1.101.26\"\n\n```\n\n\n\nNext, it tries to pull in config from the environment. These values will override any values found in any loaded configuration files.\n\n\n\nThe following env variable names are searched:\n\n\n\n* `WSSS_HTTP_PORT` Specifies the HTTP port\n\n* `WSSS_WS_PORT` Specifies the Websocket port\n\n* `WSSS_BIND_ADDRESS` Specifies the ip address to bind to\n\n\n\nFinally it parses and uses any configuration passed in via commandline arguments\n\n\n\nAvailable commandline arguments can be found via running `wsss -h` or `wsss --help`\n\n\n\nsample output:\n\n\n\n```\n\nUsage:\n\n ./target/debug/wsss [OPTIONS]\n\n\n\nProvide access to serial ports over JSON Websockets\n\n\n\noptional arguments:\n\n -h,--help show this help message and exit\n\n -p,--http_port HTTP_PORT\n\n Http Port\n\n -w,--ws_port WS_PORT Websocket Port\n\n -a,--bind_address BIND_ADDRESS\n\n Bind Address\n\n```\n\n\n\nFinally, any item not specified in any of these steps is given the default value mentioned at the beginning of this section.\n\n\n", "file_path": "DOCUMENTATION.md", "rank": 20, "score": 1.4363028935411686 }, { "content": "# websocket-serial-server (wsss)\n\n\n\n[![Build Status](https://travis-ci.org/DanielJoyce/websocket-serial-server.svg?branch=master)](https://travis-ci.org/DanielJoyce/websocket-serial-server)\n\n\n\nConnect to and read / write serial ports over websockets. In Rust\n\n\n\nThere is a need for a way to interface with hardware for software running in web browsers. WebUSB and the HTML5 serial spec are still immature.\n\n\n\nAlpha, but works for me\n\n\n\nCurrently there is no security, the connection is NOT encrypted\n\n\n\n## Features\n\n\n\n1. Written in Rust, so robust and memory safe.\n\n1. All requests and responses are JSON based\n\n1. Supports sending and receiving binary data, as base64 encoded strings\n\n1. Clients can subscribe to multiple ports\n\n1. Clients can write lock ports, so they are the only one\n\nwho can send data to it. Writing to a port can not happen\n\ntill port is write locked. This prevents corruption\n\n1. Ports are only closed when all clients have closed it\n\n1. Data read from port is broadcast to all clients who opeoned it.\n\n1. Ports are automatically cleaned up if read/write errors occur\n\n1. Opening the same port twice will not cause corruption of data\n\nsend to a client ( as seen in SPJS ).\n\n1. Supports port enumeration.\n\n1. simple programming model consisting of threads and event loops, which is fine for dozens of clients and ports.\n\n 1. As the async paradigm in rust matures, will move to that model\n\n1. Simple architecture and code base.\n\n\n\n## Documentation\n\n\n\n[Documentation](DOCUMENTATION.md)\n\n\n\n## Limitations\n\n\n\nCurrently Websocket-rs is not tokio based, so it spawns a thread per connection.\n\nFor having a few clients talk to a 3D printer, CNC machine, or other \n\nsuch use case, this is fine. \n\n\n\nOnce Websocket-rs moves to tokio, this limitation can be removed\n\n\n\nThere is no support for custom protocol or buffer handlers. That should be handled by client libraries. The purpose of wsss is to simply get data from a serial port to clients and vice-versa.\n\n\n\n## Developing\n\n\n\n### Dependencies\n\n\n", "file_path": "README.md", "rank": 21, "score": 0.898433202542698 } ]

For example, here's a simplified\n\nversion of mine:\n\n\n\n```fish\n\n#!/usr/bin/fish\n\nset dir \"$HOME/podcasts/$PODCHAMP_FEED\"\n\nmkdir -p \"$dir\"\n\ncd \"$dir\"\n\nwget -q \"$PODCAST_URI\" -O - \| \\\n\n nice ffmpeg -y \\\n\n -i pipe:0 -c:a libopus -b:a 64k \\\n\n -metadata title=\"$PODCHAMP_DATE - $PODCHAMP_TITLE\" \\\n\n -metadata artist=\"$PODCHAMP_FEED\" \\\n\n \"$PODCHAMP_DATE - $PODCHAMP_TITLE.opus\"\n", "file_path": "README.md", "rank": 45, "score": 6.517355632161014 }, { "content": "# to hell with bean dad\n\n$ podchamp rm roderickontheline\n\n```\n\n\n\nIn case you want to re-download previous episodes of a podcast (say, you lost the files, or want\n\nfresh copies to transcode them differently), you can reset the feed:\n\n\n\n```sh\n\n$ podchamp reset guaranteedaudio\n\n```\n\n\n\n## when\n\n\n\nThis will be considered done (i.e. 1.0) when I'm happy with it.\n\n\n\n## where\n\n\n\nOn linux, definitely.

developer-friendly NATS client designed with an ergonomic API designed to allow you to use this client anywhere, whether you're using `tokio` or single-threaded apps or traditional multi-threaded.\n\n\n\n## Usage\n\nThe following sample illustrates basic publish and subscribe features:\n\n\n\n```rust\n\nlet jwt = \"...\";\n\nlet seed = \"...\";\n\n \n\nlet opts = ClientOptions::builder()\n\n .cluster_uris(vec![\"nats://localhost:4222\".into()])\n\n .authentication(AuthenticationStyle::UserCredentials(\n\n jwt.to_string(),\n\n seed.to_string(),\n\n ))\n\n .build()?;\n\n\n\nlet client = Client::from_options(opts)?;\n\nclient.connect()?;\n\n\n\nclient.subscribe(\"ticker\", move \|msg\| {\n\n let symbol: SymbolReply = serde_json::from_slice(&msg.payload).unwrap();\n\n info!(\"Received stock ticker: {:?}\", symbol);\n\n Ok(())\n\n})?;\n\n```\n\n\n\nTo publish a message:\n\n\n\n```rust\n\nc.publish(&r, payload_bytes, None)?;\n\n```\n\n\n\nAnd to utilize the request/response pattern:\n\n\n\n```rust\n\n let reply = client.request(\n\n \"symbolquery\",\n\n r#\"{\"symbol\": \"NATS\"}\"#.as_bytes(),\n\n Duration::from_millis(100),\n\n)?;\n\n\n\nlet symbol: SymbolReply = serde_json::from_slice(&reply.payload).unwrap();\n\ninfo!(\"Stock symbol response: {:?}\", symbol);\n\n```\n\n\n\n## Features\n\nThe following is a list of features currently supported and planned by this client:\n\n\n\n [X] - Request/Reply\n\n* [X] - Subscribe\n\n* [X] - Publish\n\n* [X] - All authentication models, including NATS 2.0 JWT and seed keys\n\n* [X] - Adherance to protocol v1, accepts new server information whenever it's sent from NATS\n\n* [ ] - Automatic reconnect upon connection failure\n\n* [ ] - TLS support\n\n* [ ] - NATS Streaming (STAN)\n", "file_path": "README.md", "rank": 39, "score": 5.6515391769495675 }, { "content": "extern crate pretty_env_logger;\n\n#[macro_use]\n\nextern crate

Like `make`, `checkexec` runs a command only if the modified time of any dependency \n\nis newer than the modified time of the target. \n\n\n\n# Usage\n\n\n\nThe arguments are: `<target> <dependencies...> -- <command>`. The `--` is a required separator.\n\n\n\n checkexec build/my-bin src/my-program.c -- cc -o build/my-bin src/my-program.c\n\n\n\n`checkexec` executes the command directly, so shell constructs like '&&' and '\|\|' are not supported.\n\nYou can use `/bin/bash -c` as the command, but escaping is tricky. You're likely better off using two invocations of\n\n`checkexec`.\n\n\n\nYou can infer the dependency list with `--infer`, where checkexec will inspect the arguments of `<command>` for \n\naccessible paths. `--infer` will fail if no files are found.\n\n\n\n checkexec build/my-bin --infer -- cc -o build/my-bin src/my-program.c\n\n\n\n# Installation\n\n\n\n cargo install checkexec\n\n\n", "file_path": "README.md", "rank": 11, "score": 9093.384664963998 }, { "content": "# Usage Notes\n\n\n\n`checkexec` is great for when you build files from other files. Instead of relying on\n\necosystem-specific tools, you can use `checkexec` as part of any build tool. Here are some examples:\n\n\n\n- You build, resize, or sample images as part of your build command, but don't want to rebuild them unless needed.\n\n- You build C libaries as part of your Python, Rust, Node (or any other) build process.\n\n- You build Sass/Less/SCSS files and don't want to re-build them unnecessarily.\n\n\n\n`checkexec` pairs well with these tools:\n\n\n\n- [`just`](https://github.com/casey/just) fixes numerous problems with `make`, and `checkexec` adds back the \n\n conditional rebuild functionality of `make`. Together, they create a modular and modern build process and \n\n command runner.\n\n- [`watchexec`](https://github.com/watchexec/watchexec) provides live relaading/re-building, while `checkexec` \n\n has callable behavior, useful as a build step or on CI. The naming similarity is intentional.\n\n- [`fd`](https://github.com/sharkdp/fd) makes it easy to specify a dependency file list. Example here:\n\n\n\n```bash\n\n# Only run your command if a rust file has changed. Note cargo does approximately the \n\n# same thing natively, but you can easily tailor this structure to a custom case.\n\ncheckexec target/debug/hello $(fd -e rs . src) -- cargo build\n\n```\n\n\n\n### Exit codes\n\n\n\n`checkexec` exit codes behave as you would expect, specifically:\n\n\n\n- 0 (success) if the command is not run (i.e. target is up to date)\n\n- 1 if a provided dependency or the command is not found\n\n- Otherwise, when the command is run, checkexec will pass through the command's exit code.\n\n\n\n# Contributing\n\n\n\nContributions are what make the open source community such an amazing place to learn, inspire, and create. \n\nAny contributions you make are greatly appreciated.\n\n\n\nIf you have a suggestion that would make this better, please fork the repo and create a pull request. \n\nYou can also simply open an issue with the tag \"enhancement\".\n\nDon't forget to give the project a star!\n\n\n\n<p align=\"right\">(<a href=\"#top\">back to top</a>)</p>\n", "file_path": "README.md", "rank": 12, "score": 9089.824415068668 }, { "content": "The MIT License (MIT)\n\n=====================\n\n\n\nCopyright © `<year>` `<copyright holders>`\n\n\n\nPermission is hereby granted, free of charge, to any person\n\nobtaining a copy of this software and associated documentation\n\nfiles (the “Software”), to deal in the Software without\n\nrestriction, including without limitation the rights to use,\n\ncopy, modify, merge, publish, distribute, sublicense, and/or sell\n\ncopies of the Software, and to permit persons to whom the\n\nSoftware is furnished to do so, subject to the following\n\nconditions:\n\n\n\nThe above copyright notice and this permission notice shall be\n\nincluded in all copies or substantial portions of the Software.\n\n\n\nTHE SOFTWARE IS PROVIDED “AS IS”, WITHOUT WARRANTY OF ANY KIND,\n\nEXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES\n\nOF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND\n\nNONINFRINGEMENT.

native `libgphoto2` library.\n\n\n\n## Dependencies\n\nIn order to use the `gphoto` crate, you must have a Unix system with the `libgphoto2` library\n\ninstalled where it can be found by `pkg-config`.\n\n\n\nOn Debian-based Linux distributions, install the `libgphoto2-dev` package:\n\n\n\n```\n\nsudo apt-get install libgphoto2-dev\n\n```\n\n\n\nOn OS X, install `libgphoto2` with Homebrew:\n\n\n\n```\n\nbrew install libgphoto2\n\n```\n\n\n\n## Usage\n\nAdd `gphoto` as a dependency in `Cargo.toml`:\n\n\n\n```toml\n\n[dependencies]\n\ngphoto = \"0.1.2\"\n\n```\n\n\n\nImport the `gphoto` crate. The starting point for nearly all `gphoto` functionality is to create a\n\ncontext object. You can then autodetect a camera using the `Camera::autodetect()` function:\n\n\n\n```rust\n\nextern crate gphoto;\n\n\n\nuse std::path::Path;\n\n\n\nfn main() {\n\n let mut context = gphoto::Context::new().unwrap();\n\n\n\n let mut camera = gphoto::Camera::autodetect(&mut context).unwrap();\n\n let capture = camera.capture_image(&mut context).unwrap();\n\n let mut file = gphoto::FileMedia::create(Path::new(&capture.basename())).unwrap();\n\n\n\n camera.download(&mut context, &capture, &mut file).unwrap();\n\n}\n\n```\n\n\n\n### OS X Usage\n\nOS X opens cameras automatically when connected, which prevents other applications from opening the\n\ncamera device. When attempting to open a camera that is already opened by the operating system, you\n\nwill get an error message like the following:\n\n\n\n```\n\nCould not claim the USB device\n\n```\n\n\n\nTo fix this, you have to kill the `PTPCamera` process after connecting a camera to your system:\n\n\n\n```\n\nkillall PTPCamera\n\n```\n\n\n\nEach camera is opened with a separate instance of the `PTPCamera` application. If you have several\n\ncameras connected, you may want to kill individual `PTPCamera` processes instead of using `killall`.\n\n\n\n## License\n\nCopyright © 2015 David Cuddeback\n\n\n\nDistributed

Fire](https://en.wikipedia.org/wiki/Ring_of_Fire) so earthquakes and\n\nvolcano eruptions are a frequent occurrence. [PHIVOLCS](https://en.wikipedia.org/wiki/Philippine_Institute_of_Volcanology_and_Seismology) keeps\n\ntrack of all these and publishes earthquake data on its [website](https://www.phivolcs.dost.gov.ph/index.php/earthquake/earthquake-information3), \n\nand [twitter account](https://twitter.com/phivolcs_dost).\n\n\n\nThis application makes use of both sources to gather quake data and display it on a [leaflet](https://leafletjs.com/) \n\nmap. It emulates the functionality the [USGS Earthquake Map](https://earthquake.usgs.gov/earthquakes/map//). \n\n\n\n## Demo ##\n\n\n\nA running instance can be found here: [https://ph-quakes.herokuapp.com](https://ph-quakes.herokuapp.com/).\n\n\n\n## Get it and Run it ##\n\n\n\nTo run the application you will need [Rust](https://www.rust-lang.org/). Install that first. After that, run\n\nthe following:\n\n\n\n $ git clone https://github.com/fdeantoni/ph-quakes\n\n $ cd ph-quakes/server\n\n $ cargo run \n\n\n\n## Development ##\n\n\n\nThe Javascript client uses `gulp` to minify and deploy the sources. Run it as follows:\n\n\n\n $ cd ph-quakes/server/client\n\n $ gulp build\n\n \n\nOnce the updated javascript resources have been built and deployed, you can run the server as follows:\n\n\n\n $ cd .. # back to ph-quakes/server\n\n $ RUST_LOG=actix_server=info,actix_web=info,quakes_server=debug cargo run \n\n\n\nThe `quakes-server` should now be running at [http://localhost:8080].\n\n\n\nTo run the server with dummy data so as not to make any API calls from `quakes-scraper` and `quakes-twitter`,\n\npass the `TEST` env variable, i.e.:\n\n\n\n $ TEST=true cargo run\n\n \n\nThis will generate a dummy quake every 10 seconds. \n\n\n", "file_path": "README.md", "rank": 42, "score": 20559.537066404515 }, { "content": "## Leaflet Plugins ##\n\n\n\nBesides Leaflet, this project also makes use of

By default you can run the following to package for your current platform:\n\n\n\n```bash\n\nnpm run dist\n\n```\n\n\n\nThis will create a installer for your platform in the `releases` folder.\n\n\n\nYou can make builds for specific platforms (or multiple platforms) by using the options found [here](https://www.electron.build/cli). E.g. building for all platforms (Windows, Mac, Linux):\n\n\n\n```bash\n\nnpm run dist -- -mwl\n\n```\n\n\n\n## Husky and Prettier\n\nThis project comes with both Husky and Prettier setup to ensure a consistent code style. \n\n\n\nTo change the code style, you can change the configuration in `.prettierrc`. \n\n\n\nIn case you want to get rid of this, you can removing the following from `package.json`:\n\n\n\n1. Remove `precommit` from the `scripts` section\n\n1. Remove the `lint-staged` section\n\n1. Remove `lint-staged`, `prettier`, `eslint-config-prettier`, and `husky` from the `devDependencies`\n\n\n\nAlso remove all mentions of Prettier from the `extends` section in `.eslintrc.json`.\n",

`http_port` The HTTP port to bind to, defaults to 10080\n\n* `ws_port` The port the websocket listens on, defaults to 10081\n\n* `bind_address` The ip address the server binds to, defaults to 127.0.0.1 ( localhost )\n\n\n\nWhen wsss starts, it first tries to load configuration information from the following files: \n\n\n\n1. The file specified by the environment variable `WSS_CONF_FILE`\n\n1. It then tries to load the file in `/etc/wsss/wsss_conf.toml`\n\n1. It then tries to load a `wsss_conf.toml` file located in the same directory as the wsss executable\n\n\n\n**Only the first file found is loaded.**\n\n\n\nThe configuration file makes use of [TOML](https://github.com/toml-lang/toml).

Written in Rust, so robust and memory safe.\n\n1. All requests and responses are JSON based\n\n1. Supports sending and receiving binary data, as base64 encoded strings\n\n1. Clients can subscribe to multiple ports\n\n1. Clients can write lock ports, so they are the only one\n\nwho can send data to it. Writing to a port can not happen\n\ntill port is write locked. This prevents corruption\n\n1. Ports are only closed when all clients have closed it\n\n1. Data read from port is broadcast to all clients who opeoned it.\n\n1. Ports are automatically cleaned up if read/write errors occur\n\n1. Opening the same port twice will not cause corruption of data\n\nsend to a client ( as seen in SPJS ).\n\n1. Supports port enumeration.\n\n1. simple programming model consisting of threads and event loops, which is fine for dozens of clients and ports.\n\n 1.

The purpose of wsss is to simply get data from a serial port to clients and vice-versa.\n\n\n\n## Developing\n\n\n\n### Dependencies\n\n\n", "file_path": "README.md", "rank": 21, "score": 0.898433202542698 } ]

developer-friendly NATS client designed with an ergonomic API designed to allow you to use this client anywhere, whether you're using `tokio` or single-threaded apps or traditional multi-threaded.\n\n\n\n## Usage\n\nThe following sample illustrates basic publish and subscribe features:\n\n\n\n```rust\n\nlet jwt = \"...\";\n\nlet seed = \"...\";\n\n \n\nlet opts = ClientOptions::builder()\n\n .cluster_uris(vec![\"nats://localhost:4222\".into()])\n\n .authentication(AuthenticationStyle::UserCredentials(\n\n jwt.to_string(),\n\n seed.to_string(),\n\n ))\n\n .build()?;\n\n\n\nlet client = Client::from_options(opts)?;\n\nclient.connect()?;\n\n\n\nclient.subscribe(\"ticker\", move |msg| {\n\n let symbol: SymbolReply = serde_json::from_slice(&msg.payload).unwrap();\n\n info!(\"Received stock ticker: {:?}\", symbol);\n\n Ok(())\n\n})?;\n\n```\n\n\n\nTo publish a message:\n\n\n\n```rust\n\nc.publish(&r, payload_bytes, None)?;\n\n```\n\n\n\nAnd to utilize the request/response pattern:\n\n\n\n```rust\n\n let reply = client.request(\n\n \"symbolquery\",\n\n r#\"{\"symbol\": \"NATS\"}\"#.as_bytes(),\n\n Duration::from_millis(100),\n\n)?;\n\n\n\nlet symbol: SymbolReply = serde_json::from_slice(&reply.payload).unwrap();\n\ninfo!(\"Stock symbol response: {:?}\", symbol);\n\n```\n\n\n\n## Features\n\nThe following is a list of features currently supported and planned by this client:\n\n\n\n* [X] - Request/Reply\n\n* [X] - Subscribe\n\n* [X] - Publish\n\n* [X] - All authentication models, including NATS 2.0 JWT and seed keys\n\n* [X] - Adherance to protocol v1, accepts new server information whenever it's sent from NATS\n\n* [ ] - Automatic reconnect upon connection failure\n\n* [ ] - TLS

This module only exposes one public structure: `KNNEstimator`, which can be\n\n//! used as follows:\n\n//! 1) Init `KNNEstimator` with selected evaluation (test) data;\n\n//! 2) Add a training example with `add_example()`.\n\n//! 3) Get the estimate (i.e., error) on the test data with `get_error()`.\n\n//! 4) Repeat from 2), until training data is finished.\n\n//!\n\n//! # Examples\n\n//!\n\n//! ```\n\n//! #[macro_use(array)]\n\n//! extern crate ndarray;\n\n//! extern crate fbleau;\n\n//!\n\n//! # fn main() {\n", "file_path": "src/estimates/knn.rs", "rank": 53, "score": 45730.268795664444 }, { "content": " .iter()\n\n .map(|e| match e {\n\n 0 => false,\n\n 1 => true,\n\n _ => panic!(\"{}\", \"errors must contain values in {0,1}\"),\n\n })\n\n .collect::<Vec<_>>()\n\n }\n\n}\n\n\n\n#[cfg(test)]\n\nmod tests {\n\n use super::*;\n\n use crate::estimates::*;\n\n\n\n #[test]\n\n fn knn_init() {\n\n let train_x = array![[8.], [3.], [1.], [4.], [5.], [7.], [2.], [6.]];\n\n let train_y = array![0, 0, 0, 1, 0, 1, 1, 2];\n\n let x = array![0.];\n", "file_path": "src/estimates/knn.rs", "rank": 54, "score": 45729.70065423505 }, { "content": " knn.add_example(&x, *y).unwrap();\n\n assert_eq!(\n\n knn.predictions,\n\n expected_preds[expected_preds.len() - 1 - i]\n\n );\n\n assert_eq!(\n\n knn.get_error(),\n\n expected_error[expected_error.len() - 1 - i]\n\n );\n\n }\n\n\n\n // Test when changing k.\n\n let max_n = train_x.nrows();\n\n // Custom k_from_n.\n\n let k_from_n = Box::new(|n| match n {\n\n 0..=3 => 1,\n\n 4..=6 => 4,\n\n _ => 5,\n\n });\n\n let mut knn = KNNEstimator::new(\n", "file_path": "src/estimates/knn.rs", "rank": 55, "score": 45729.67870639965 }, { "content": " pub fn from_data(\n\n train_x: &ArrayView2<f64>,\n\n train_y: &ArrayView1<Label>,\n\n test_x: &ArrayView2<f64>,\n\n test_y: &ArrayView1<Label>,\n\n max_n: usize,\n\n distance: D,\n\n strategy: KNNStrategy,\n\n ) -> KNNEstimator<D> {\n\n assert_eq!(train_x.ncols(), test_x.ncols());\n\n assert_eq!(train_x.nrows(), train_y.len());\n\n assert_eq!(test_x.nrows(), test_y.len());\n\n assert!(!train_x.is_empty());\n\n assert!(!test_x.is_empty());\n\n\n\n // How we select k given n.\n\n let k_from_n = knn_strategy(strategy);\n\n // Maximum number of neighbors to store (excluding ties).\n\n let max_k = k_from_n(max_n);\n\n\n", "file_path": "src/estimates/knn.rs", "rank": 56, "score": 45728.835005831235 }, { "content": " fn ties_after_max_k() {\n\n let max_k = 5;\n\n let distance = euclidean_distance;\n\n\n\n let train_x = array![[0.], [0.], [0.], [1.], [1.], [1.], [1.], [1.], [0.]];\n\n let train_y = array![0, 1, 1, 1, 0, 0, 0, 0, 1];\n\n\n\n let x = array![0.];\n\n let mut nn = NearestNeighbors::from_data(\n\n &x.view(),\n\n &train_x.view(),\n\n &train_y.view(),\n\n max_k,\n\n distance,\n\n );\n\n let distances_from_x: Vec<_> = nn.neighbors.iter().map(|neigh| neigh.distance).collect();\n\n assert_eq!(distances_from_x, vec![0., 0., 0., 0., 1.]);\n\n assert_eq!(nn.extra_ties_dist, Some(1.));\n\n println!(\"{:?}\", nn.extra_ties);\n\n // NOTE: equally valid would be to have extra_ties[0] == Some(4)\n", "file_path": "src/estimates/knn.rs", "rank": 57, "score": 45728.596970395956 }, { "content": " // Different labels.\n\n let train_y = array![0, 0, 1, 1, 0, 0, 0, 0, 1];\n\n let nn = NearestNeighbors::from_data(\n\n &x.view(),\n\n &train_x.view(),\n\n &train_y.view(),\n\n max_k,\n\n euclidean_distance,\n\n );\n\n assert_eq!(nn.predict(5).unwrap(), 0);\n\n }\n\n\n\n /* FIXME: verify this test is still necessary.\n\n #[test]\n\n /// KNNEstimator's parameter updated_k should take ties into account.\n\n fn test_updated_k() {\n\n let test_x = array![[0.]];\n\n let test_y = array![1];\n\n\n\n let k = 1;\n", "file_path": "src/estimates/knn.rs", "rank": 58, "score": 45728.51969372989 }, { "content": " let mut max_k = 8;\n\n\n\n let knn = NearestNeighbors::from_data(\n\n &x.view(),\n\n &train_x.view(),\n\n &train_y.view(),\n\n max_k,\n\n euclidean_distance,\n\n );\n\n\n\n let distances_from_x: Vec<_> = knn.neighbors.iter().map(|neigh| neigh.distance).collect();\n\n assert_eq!(distances_from_x, vec![1., 2., 3., 4., 5., 6., 7., 8.]);\n\n\n\n // Reduce max_k.\n\n max_k = 5;\n\n let knn = NearestNeighbors::from_data(\n\n &x.view(),\n\n &train_x.view(),\n\n &train_y.view(),\n\n max_k,\n", "file_path": "src/estimates/knn.rs", "rank": 59, "score": 45728.44352834962 }, { "content": " max_k: usize,\n\n distance: D,\n\n ) -> NearestNeighbors<D> {\n\n assert!(max_k > 0);\n\n\n\n let mut knn = NearestNeighbors::new(x, max_k, distance);\n\n\n\n for (xi, yi) in train_x.outer_iter().zip(train_y) {\n\n // NOTE: we use std::usize::MAX as a bogus label to split ties in\n\n // predict();

Like `make`, `checkexec` runs a command only if the modified time of any dependency \n\nis newer than the modified time of the target. \n\n\n\n# Usage\n\n\n\nThe arguments are: `<target> <dependencies...> -- <command>`. The `--` is a required separator.\n\n\n\n checkexec build/my-bin src/my-program.c -- cc -o build/my-bin src/my-program.c\n\n\n\n`checkexec` executes the command directly, so shell constructs like '&&' and '||' are not supported.\n\nYou can use `/bin/bash -c` as the command, but escaping is tricky. You're likely better off using two invocations of\n\n`checkexec`.\n\n\n\nYou can infer the dependency list with `--infer`, where checkexec will inspect the arguments of `<command>` for \n\naccessible paths. `--infer` will fail if no files are found.\n\n\n\n checkexec build/my-bin --infer -- cc -o build/my-bin src/my-program.c\n\n\n\n# Installation\n\n\n\n cargo install checkexec\n\n\n", "file_path": "README.md", "rank": 11, "score": 9093.384664963998 }, { "content": "# Usage Notes\n\n\n\n`checkexec` is great for when you build files from other files. Instead of relying on\n\necosystem-specific tools, you can use `checkexec` as part of any build tool. Here are some examples:\n\n\n\n- You build, resize, or sample images as part of your build command, but don't want to rebuild them unless needed.\n\n- You build C libaries as part of your Python, Rust, Node (or any other) build process.\n\n- You build Sass/Less/SCSS files and don't want to re-build them unnecessarily.\n\n\n\n`checkexec` pairs well with these tools:\n\n\n\n- [`just`](https://github.com/casey/just) fixes numerous problems with `make`, and `checkexec` adds back the \n\n conditional rebuild functionality of `make`. Together, they create a modular and modern build process and \n\n command runner.\n\n- [`watchexec`](https://github.com/watchexec/watchexec) provides live relaading/re-building, while `checkexec` \n\n has callable behavior, useful as a build step or on CI. The naming similarity is intentional.\n\n- [`fd`](https://github.com/sharkdp/fd) makes it easy to specify a dependency file list. Example here:\n\n\n\n```bash\n\n# Only run your command if a rust file has changed. Note cargo does approximately the \n\n# same thing natively, but you can easily tailor this structure to a custom case.\n\ncheckexec target/debug/hello $(fd -e rs . src) -- cargo build\n\n```\n\n\n\n### Exit codes\n\n\n\n`checkexec` exit codes behave as you would expect, specifically:\n\n\n\n- 0 (success) if the command is not run (i.e. target is up to date)\n\n- 1 if a provided dependency or the command is not found\n\n- Otherwise, when the command is run, checkexec will pass through the command's exit code.\n\n\n\n# Contributing\n\n\n\nContributions are what make the open source community such an amazing place to learn, inspire, and create. \n\nAny contributions you make are **greatly appreciated**.\n\n\n\nIf you have a suggestion that would make this better, please fork the repo and create a pull request. \n\nYou can also simply open an issue with the tag \"enhancement\".\n\nDon't forget to give the project a star!\n\n\n\n<p align=\"right\">(<a href=\"#top\">back to top</a>)</p>\n", "file_path": "README.md", "rank": 12, "score": 9089.824415068668 }, { "content": "The MIT License (MIT)\n\n=====================\n\n\n\nCopyright © `<year>` `<copyright holders>`\n\n\n\nPermission is hereby granted, free of charge, to any person\n\nobtaining a copy of this software and associated documentation\n\nfiles (the “Software”), to deal in the Software without\n\nrestriction, including without limitation the rights to use,\n\ncopy, modify, merge, publish, distribute, sublicense, and/or sell\n\ncopies of the Software, and to permit persons to whom the\n\nSoftware is furnished to do so, subject to the following\n\nconditions:\n\n\n\nThe above copyright notice and this permission notice shall be\n\nincluded in all copies or substantial portions of the Software.\n\n\n\nTHE SOFTWARE IS PROVIDED “AS IS”, WITHOUT WARRANTY OF ANY KIND,\n\nEXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES\n\nOF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND\n\nNONINFRINGEMENT.

native `libgphoto2` library.\n\n\n\n## Dependencies\n\nIn order to use the `gphoto` crate, you must have a Unix system with the `libgphoto2` library\n\ninstalled where it can be found by `pkg-config`.\n\n\n\nOn Debian-based Linux distributions, install the `libgphoto2-dev` package:\n\n\n\n```\n\nsudo apt-get install libgphoto2-dev\n\n```\n\n\n\nOn OS X, install `libgphoto2` with Homebrew:\n\n\n\n```\n\nbrew install libgphoto2\n\n```\n\n\n\n## Usage\n\nAdd `gphoto` as a dependency in `Cargo.toml`:\n\n\n\n```toml\n\n[dependencies]\n\ngphoto = \"0.1.2\"\n\n```\n\n\n\nImport the `gphoto` crate. The starting point for nearly all `gphoto` functionality is to create a\n\ncontext object. You can then autodetect a camera using the `Camera::autodetect()` function:\n\n\n\n```rust\n\nextern crate gphoto;\n\n\n\nuse std::path::Path;\n\n\n\nfn main() {\n\n let mut context = gphoto::Context::new().unwrap();\n\n\n\n let mut camera = gphoto::Camera::autodetect(&mut context).unwrap();\n\n let capture = camera.capture_image(&mut context).unwrap();\n\n let mut file = gphoto::FileMedia::create(Path::new(&*capture.basename())).unwrap();\n\n\n\n camera.download(&mut context, &capture, &mut file).unwrap();\n\n}\n\n```\n\n\n\n### OS X Usage\n\nOS X opens cameras automatically when connected, which prevents other applications from opening the\n\ncamera device. When attempting to open a camera that is already opened by the operating system, you\n\nwill get an error message like the following:\n\n\n\n```\n\nCould not claim the USB device\n\n```\n\n\n\nTo fix this, you have to kill the `PTPCamera` process after connecting a camera to your system:\n\n\n\n```\n\nkillall PTPCamera\n\n```\n\n\n\nEach camera is opened with a separate instance of the `PTPCamera` application. If you have several\n\ncameras connected, you may want to kill individual `PTPCamera` processes instead of using `killall`.\n\n\n\n## License\n\nCopyright © 2015 David Cuddeback\n\n\n\nDistributed

Fire](https://en.wikipedia.org/wiki/Ring_of_Fire) so earthquakes and\n\nvolcano eruptions are a frequent occurrence. [PHIVOLCS](https://en.wikipedia.org/wiki/Philippine_Institute_of_Volcanology_and_Seismology) keeps\n\ntrack of all these and publishes earthquake data on its [website](https://www.phivolcs.dost.gov.ph/index.php/earthquake/earthquake-information3), \n\nand [twitter account](https://twitter.com/phivolcs_dost).\n\n\n\nThis application makes use of both sources to gather quake data and display it on a [leaflet](https://leafletjs.com/) \n\nmap. It emulates the functionality the [USGS Earthquake Map](https://earthquake.usgs.gov/earthquakes/map//). \n\n\n\n## Demo ##\n\n\n\nA running instance can be found here: [https://ph-quakes.herokuapp.com](https://ph-quakes.herokuapp.com/).\n\n\n\n## Get it and Run it ##\n\n\n\nTo run the application you will need [Rust](https://www.rust-lang.org/). Install that first. After that, run\n\nthe following:\n\n\n\n $ git clone https://github.com/fdeantoni/ph-quakes\n\n $ cd ph-quakes/server\n\n $ cargo run \n\n\n\n## Development ##\n\n\n\nThe Javascript client uses `gulp` to minify and deploy the sources. Run it as follows:\n\n\n\n $ cd ph-quakes/server/client\n\n $ gulp build\n\n \n\nOnce the updated javascript resources have been built and deployed, you can run the server as follows:\n\n\n\n $ cd .. # back to ph-quakes/server\n\n $ RUST_LOG=actix_server=info,actix_web=info,quakes_server=debug cargo run \n\n\n\nThe `quakes-server` should now be running at [http://localhost:8080].\n\n\n\nTo run the server with dummy data so as not to make any API calls from `quakes-scraper` and `quakes-twitter`,\n\npass the `TEST` env variable, i.e.:\n\n\n\n $ TEST=true cargo run\n\n \n\nThis will generate a dummy quake every 10 seconds. \n\n\n", "file_path": "README.md", "rank": 42, "score": 20559.537066404515 }, { "content": "## Leaflet Plugins ##\n\n\n\nBesides Leaflet, this project also makes use of

started\n\n\n\nTo get started with running the client you probably want the podium daemon running. \n\n\n\n1. `cargo run -- -s ./test_files/` from the root of the repo\n\n2. `npm install` from this directory\n\n3. `npm run start-dev` to start up the client\n\n\n\n\n\n## Usage\n\nBoth processes have to be started **simultaneously** in different console tabs:\n\n\n\n```bash\n\nnpm run start-renderer-dev\n\nnpm run start-main-dev\n\n```\n\n\n\nThis will start the application with hot-reload so you can instantly start developing your application.\n\n\n\nYou can also run do the following to start both in a single process:\n\n\n\n```bash\n\nnpm run start-dev\n\n```\n\n\n\n## Packaging\n\nWe use [Electron builder](https://www.electron.build/) to build and package the application. By default you can run the following to package for your current platform:\n\n\n\n```bash\n\nnpm run dist\n\n```\n\n\n\nThis will create a installer for your platform in the `releases` folder.\n\n\n\nYou can make builds for specific platforms (or multiple platforms) by using the options found [here](https://www.electron.build/cli). E.g. building for all platforms (Windows, Mac, Linux):\n\n\n\n```bash\n\nnpm run dist -- -mwl\n\n```\n\n\n\n## Husky and Prettier\n\nThis project comes with both Husky and Prettier setup to ensure a consistent code style. \n\n\n\nTo change the code style, you can change the configuration in `.prettierrc`. \n\n\n\nIn case you want to get rid of this, you can removing the following from `package.json`:\n\n\n\n1. Remove `precommit` from the `scripts` section\n\n1. Remove the `lint-staged` section\n\n1. Remove `lint-staged`, `prettier`, `eslint-config-prettier`, and `husky` from the `devDependencies`\n\n\n\nAlso remove all mentions of Prettier from the `extends` section in `.eslintrc.json`.\n",
