VS Code's default configuration for a ruler is demonstrated below. "editor.ruler": 80 The issue I am having with the default VS Code configuration (as shown above) is that it only renders a single ruler. In the Sublime Text Editor I can render as many rulers as I like using the following Sublime configuration. "rulers": [72, 80, 100, 120] Is it possible to render multiple rulers in V.S. Code. If i
I have a README.md file for my project underscore-cli, and I want to document the --color flag. Currently, the only way to do this is with a screenshot (which can be stored in the project repository): But screenshots aren't text, preventing readers from copy/pasting the command in the screenshot. They're also a pain to create / edit / maintain, and are slower for browsers to load. The modern web u
I am unable to install ionic through npm. Are there any logs that I can check to see what's wrong and if yes, where are they located? What I see is the waiting stick dancing forever. I've waited for an hour or so but nothing changes.
Bitccode is actually just the LLVM intermediate language. When you compile source code using the LLVM toolchain, source code is translated into an intermediate language, named Bitcode. This Bitcode is then analyzed, optimized and finally translated to CPU instructions for the desired target CPU. The advantage of doing it that way is that all LLVM based frontends (like clang) only need to translate
I have a fresh install of Python 3.3.4 on a Windows Server 2008 R2 machine. I've successfully installed the latest versions of Setuptools, Pip and Virtualenv globally: python ez_setup.py easy_install pip pip install virtualenv Now when I try to set up a virtualenv using virtualenv ENV I get the following stack trace: New python executable in ENV\Scripts\python.exe Installing setuptools, pip...

Yes, this is possible using the macos-10.15 (which is currently the macos-latest) environment. You could also try to go with macos-11.0, but there currently seems to be no stable VirtualBox release for Big Sur. I created a small example project at https://github.com/jonashackt/vagrant-github-actions Assume you have a Vagrantfile inside your repo like this: Vagrant.configure("2") do |config| config
I was reading Agner Fog's optimization manuals, and I came across this example: double data[LEN]; void compute() { const double A = 1.1, B = 2.2, C = 3.3; int i; for(i=0; i<LEN; i++) { data[i] = A*i*i + B*i + C; } } Agner indicates that there's a way to optimize this code - by realizing that the loop can avoid using costly multiplications, and instead use the "deltas" that are applied per iteratio
The version 13.2 of Node.js allows ESM modules and a new package.json field, called exports, to select and rewrite exported files. Before 13.2, I was importing files from the dist folder of my library with: import myfile from 'mylibrary/dist/myfile' With 13.2, I added this to my package.json: exports: { "./": "./dist/" } And tried to import files with: import myfile from 'mylibrary/myfile' But Typ
Does SQLite3 safely handle concurrent access by multiple processes reading/writing from the same DB? Are there any platform exceptions to that?
I was trying to follow the docs and created vite.config.js like this: const config = { outDir: '../wwwroot/', proxy: { // string shorthand '/foo': 'http://localhost:4567', // with options '/api': { target: 'http://jsonplaceholder.typicode.com', changeOrigin: true, rewrite: path => path.replace(/^\/api/, '') } } }; export default config; And tried to test it with following calls: fetch('/foo'); fet
I've read an article about JavaScript parseInt, which had this question: parseInt(0.5); // => 0 parseInt(0.05); // => 0 parseInt(0.005); // => 0 parseInt(0.0005); // => 0 parseInt(0.00005); // => 0 parseInt(0.000005); // => 0 parseInt(0.0000005); // => 5 Why is this happening?
I am currently setting up a boilerplate with React, TypeScript, styled components, Webpack, etc., and I am getting an error when trying to run ESLint: Error: Must use import to load ES Module Here is a more verbose version of the error: /Users/ben/Desktop/development projects/react-boilerplate-styled-context/src/api/api.ts 0:0 error Parsing error: Must use import to load ES Module: /Users/ben/Desk
Chrome 65 removed support for the download attribute on anchor elements with cross-origin hrefs: Block cross-origin <a download> To avoid what is essentially a user-mediated cross-origin information leakage, Blink will now ignore the presence of the download attribute on anchor elements with cross origin attributes. Note that this applies to HTMLAnchorElement.download as well as to the element its
I made a bubble sort implementation in C, and was testing its performance when I noticed that the -O3 flag made it run even slower than no flags at all! Meanwhile -O2 was making it run a lot faster as expected. Without optimisations: time ./sort 30000 ./sort 30000 1.82s user 0.00s system 99% cpu 1.816 total -O2: time ./sort 30000 ./sort 30000 1.00s user 0.00s system 99% cpu 1.005 total -O3: time .
Is there a way to create some kind of random or unique value in a CloudFormation template? Why I need this. In our templates we have a number of custom-named resources, for instance AWS::AutoScaling::LaunchConfiguration with specified LaunchConfigurationName or AWS::AutoScaling::AutoScalingGroup with specified AutoScalingGroupName. When updating stacks, we often get the following error: CloudForma
I'm taking a photo with the newest camera plugin version and I'm using code from flutter example. This is how I pick a camera: final cameras = await availableCameras(); final firstCamera = cameras.first; This is inside init: _cameraController = CameraController( widget.camera, ResolutionPreset.medium, enableAudio: false, ); This is the rest of the relevant code: Future _takePhoto(BuildContext cont
I'm looking for a regular expression to validate hex colors in ASP.NET C# and am also looking code for validation on server side. For instance: #CCCCCC
I know that for a network card, OS must allocate tx/rx rings for it so that when OS wants to receive/transmit packets, the network card will know where the packets are and which packets are to be transmit. And when I read about DMA, I see something named DMA ring buffer. Are the DMA ring and tx/rx ring the same thing?Or what is the relationship?
Question: is there a simple sh/bash/zsh/fish/... command to print the absolute path of whichever file I feed it? Usage case: I'm in directory /a/b and I'd like to print the full path to file c on the command-line so that I can easily paste it into another program: /a/b/c. Simple, yet a little program to do this could probably save me 5 or so seconds when it comes to handling long paths, which in t
Is there a way to make it so that jest always mocks my modules so I don't need to include it in all my jest tests? Currently I have a config file // src/__mocks__/config.js export default { dbConfig: 'TestDBConfiguration' }; // src/config.js export default { dbConfig: ... // Some other stuff }; To run my unit tests I have to use the mocked config.js. Currently in all my unit tests I have to includ
So, how do I know the scroll direction when the event it's triggered? In the returned object the closest possibility I see is interacting with the boundingClientRect kind of saving the last scroll position but I don't know if handling boundingClientRect will end up on performance issues. Is it possible to use the intersection event to figure out the scroll direction (up / down)? I have added this
I've created a new Rails 6.1 application from scratch with Ruby 3.0.0. I've run db:create and generated a single model with some string columns, followed by rails db:migrate. I ran rails test but got this require rexml error: /Users/froop/.rvm/gems/ruby-3.0.0/gems/bootsnap-1.5.1/lib/bootsnap/load_path_cache/core_ext/kernel_require.rb:34:in `require': cannot load such file -- rexml/document (LoadEr
I use the new command line tools for Android because the old sdk-tools repository of Android isn't available anymore. So I changed my gitlab-ci to load the commandlintools. But when I try to run it I get the following error: Warning: Could not create settings java.lang.IllegalArgumentException at com.android.sdklib.tool.sdkmanager.SdkManagerCliSettings.<init>(SdkManagerCliSettings.java:428) at com
as the title says, I want to perform a find (one) for a document, by _id, and if doesn't exist, have it created, then whether it was found or was created, have it returned in the callback. I don't want to update it if it exists, as I've read findAndModify does. I have seen many other questions on Stackoverflow regarding this but again, don't wish to update anything. I am unsure if by creating (of
I have two "unlocked" devices, an iPad mini 3, and a Galaxy Edge 6, both endowed with a terminal and a minimalistic set of unix commands. I thought both devices have arm64 processors but when I ran uname -a on both devices I got the following : for the iPad mini 3 : xxxxs-iPad:/var/mobile root# uname -a Darwin xxxx-iPad 14.0.0 Darwin Kernel Version 14.0.0: Wed Jun 24 00:50:15 PDT 2015; root:xnu-27
