How to download single file from github?

Problem:

Often, you will need a single file to download from github, but you can't figure out how to do that. In such a case, a lot of people will suggest that you will need to download the whole repository. But that's not a useful suggestion and you know it. So what to do?

Solution:

In such a case, first click the view raw option in github ui. This will redirect into a new tab generally and show the rawgithubusercontent.com/... site and the raw content in that tab. Avoid this. Get this raw content in the same tab. This will create a similar rawgithubusercontent.com/... url.

Now, using this url, use curl <url> to fetch this content. This will download the raw content in your computer.

Installation (if needed):

For linux and mac, you will have this curl installed by default. For windows, you need to install it if your version is not later than windows 10. To try out the installation see Testing your cURL installation below. [the following part is taken from zendesk website]

You can download and install cURL as follows.

In Windows, create a new folder called curl in your C: drive.

C:\curl
Go to http://curl.haxx.se/download.html and download one of the following zip files:
- If you have a Windows 64 system, scroll to the Win64 - Generic section and look for the latest Win64 ia64 zip version with SSL support. It's normally second in the list. Click the version number to start the download.
- If you have a Windows 32 system, scroll to the Win32 - Generic section and look for the latest Win32 zip version with SSL support. It's normally second in the list. Click the version number to start the download.
Unzip the downloaded file and move the curl.exe file to your C:\curl folder.
Go to http://curl.haxx.se/docs/caextract.html and download the digital certificate file named cacert.pem.

The PEM file contains a bundle of valid digital certificates. The certificates are used to verify the authenticity of secure websites. They're distributed by certificate authority (CA) companies such as GlobalSign and VeriSign. The PEM file allows cURL to connect securely to the Zendesk API using the Secure Sockets Layer (SSL) protocol.
Move the cacert.pem file to your C:\curl folder and rename it curl-ca-bundle.crt.
Add the curl folder path to your Windows PATH environment variable so that the curl command is available from any location at the command prompt. Update the variable as follows:
1. In the Start menu, right-click This PC and select More > Properties.
  
  Note: In Windows 7, right-click Computer and select Properties.
2. Click Advanced System Settings.
3. In the Advanced tab, click the Environment Variables button on the lower right side.
4. Select the "Path" variable in System Variables, and click Edit.
5. In the Edit environment variable dialog box, click New and add the path to the curl.exe file. Example: C:\curl.
  
  Windows 7: In the Variable Value textbox, append a semicolon to the value, followed by the path to the curl.exe file. Example: ;C:\curl
6. Keep clicking OK to accept the change and close the dialog box.

Now that you have curl in your windows computer also, you can curl the url in above mentioned procedure.

Conclusion:

So in this article, not only we resolved the hiccup of downloading single file from github, but we also saw how to use curl and how to download curl if you don't have it in your machine. Hope it helped you.

20 Must-Know Math Puzzles for Data Science Interviews: Test Your Problem-Solving Skills

Introduction: When preparing for a data science interview, brushing up on your coding and statistical knowledge is crucial—but math puzzles also play a significant role. Many interviewers use puzzles to assess how candidates approach complex problems, test their logical reasoning, and gauge their problem-solving efficiency. These puzzles are often designed to test not only your knowledge of math but also your ability to think critically and creatively. Here, we've compiled 20 challenging yet exciting math puzzles to help you prepare for data science interviews. We’ll walk you through each puzzle, followed by an explanation of the solution. 1. The Missing Dollar Puzzle Puzzle: Three friends check into a hotel room that costs $30. They each contribute $10. Later, the hotel realizes there was an error and the room actually costs $25. The hotel gives $5 back to the bellboy to return to the friends, but the bellboy, being dishonest, pockets $2 and gives $1 back to each friend. No...

GAM model : PyGAM package details Analysis and possible issue resolving

Introduction: picture credit to peter laurinec. I have been studying about PyGAM package for last couple of days. Now, I am planning to thoroughly analyze the code of PyGAM package with necessary description of GAM model and sources whenever necessary. This is going to be a long post and very much technical in nature. Pre-requisites: For understanding the coding part of PyGAM package, first you have to learn what is a GAM model. GAM stands for generalized additive model, i.e. it is a type of statistical modeling where a target variable Y is roughly represented by additive combination of set of different functions. In formula it can be written as: g(E[Y]) = f 1 (x 1 ) + f 2 (x 2 ) + f 3 (x 3 ,x 4 )+...etc where g is called a link function and f are different types of functions. In technical terms, in GAM model, theoretically expectation of the link transformed target variable is assume...

Pyarabic: python package for Arabic language

Introduction: In languages which are non-english and non-european as well, NLP work has progressed slowly in the last few decades because of the lesser number of scholars working on them as well as a lack of global interest in them. But now the time has changed and people from all over the world are collaborating on these lesser explored libraries and they are building resources for working on these languages with the same ease with that of english. Pyarabic is a package created from such a similar effort which deals with the intricate details of the arabic language and helps processing all kinds of arabic texts. While trying to learn it, being from a non-arab background, I couldn't read lots of parts of the main readthedocs site and had to work my around it. So in this blog post, I will summarize my learnings in english language, so that you can learn it and use the package with much more ease than me. [Credit where credit is due: this article heavily uses the ac...
