   • define path to a file in my google drive in a colab notebook

     Top Answer

     Answered Oct 12, 2019 · 0 votes

     I think you can't use the Google Drive's file directly from Colab. First, you have to run the code below in colab to mount Google Drive to Colab:

     from google.colab import drivedrive.mount('/gdrive')%cd /gdrive-

     Then

     %cd /gdrive/My Drive/fixit%ls%cp -r 'data actual' /content/sample_data-

     And change your path to dataset to this:

     path_to_dataset = 'data actual'-

     Or maybe you don't need path_to_dataset anymore, just delete it, and change code to this:

     path_to_movie_lines = 'movie_lines.txt' path_to_movie_conversations = 'movie_conversations.txt'-

     Just try delete path to dataset or not. One of this two ways will work.

     In my old project, i don't use path to dataset, i just use dataset .txt files directly like they are in the same folder with my notebook.

     P/S: Sory for my bad english.

   • In Computer Science, what's the opposite of a dependency?

     Top Answer

     Answered Dec 20, 2021 · 25 votes

     The opposite of a dependency is independency.

     The inverse of a dependency is a dependent. This term applies specifically in programming to refer to the piece of code that requires the dependency to run.

     The term is widely used. Some quotes to support the claim:

     • In the book Dependency Injection: Design patterns using Spring and Guice (so a book that is mainly about dependencies in the programming context):Dependency — A specific service that is required by another object to fulfill its function.Dependent — A client object that needs a dependency (or dependencies) in order to perform its function.
     • In the book The Unified Modeling Language Reference Manual, 2nd ed by Booch, Rumbaugh and Jacobson:Dependency: A relationship between two elements in which a change to one element (the supplier) may affect or supply information needed by the other element (the client). (...) the dependent elements are called clients.
     • In the semantic versioning manifesto, they explain how semver can allow to release new versions of dependencies without disrupting dependent software or packages.
     • In the documentation of Maven:Compile dependencies are available in all classpaths of a project. Furthermore, those dependencies are propagated to dependent projects.
     • Last but not least, linguist have also confirmed suitability of this term for very similar dependency management needs.

     Dependency being a relation between something that is dependent and something that it depends on, there is a little residual ambiguity on the direction that is meant. Regardless the terms used, it's recommended to provide the definitions. Supplier/Client are alternatives that are imho more easily understood although not universally suitable.

   • Compact Objects in JavaScript

     Compacting an object refers to removing properties with false values (like null, undefined, 0, false, “”, NaN, etc.). Objects are used to store collections of data and more complex entities. They can be extended and manipulated in various ways to suit different programming needs. One interesting aspect of JavaScript objects is their compact representation, which allows for efficient storage and retrieval of properties.

     Below are the approaches for compacting objects in JavaScript:

     • Using Object Literals
     • Using a simple for…in loop
     • Using Lodash library _.pickBy method

     Using Object Literals Object literals let you easily create objects by listing their properties and values. They’re essential for making data structures that are simple and organized.

     Example: Demonstrates the creation and access of properties in a compact JavaScript object using object literals.

     -function createCompObj(obj) { const compObj = {}; Object.keys(obj).forEach(key => { const value = obj[key]; if (value !== null && value !== undefined && value !== false) { compObj[key] = value; } }); return compObj;}const originalObj = { name: 'GFG', age: 50, city: null, state: undefined, active: false, country: 'INDIA'};const compObj = createCompObj(originalObj);console.log(compObj);
