  • #100DaysOfCode, Day 001 – Dates & Times

    We begin with a date/time project.
    Python has objects (primitives) to deal with dates and times.
    They are part of the datetime module, which is part of the Python Standard Library.

  • Top 25 Python Libraries for Data Science Projects

    This post is attempting to enlighten you about the most useful and popular Python libraries used by data scientists. And why only Python, because it has been the leading programming language for solving real-time data science problems.

    These libraries have been tested to give excellent results in various areas like Machine Learning (ML), Deep Learning, Artifical Intelligence (AI), and Data Science challenges. Hence, you can confidently induct any of these without putting too much time and effort in R&D.

    In every data science project, programmers, even architects, use to spend considerable time researching the Python libraries that can be the best fit. And we believe this post might give them the right heads up, cut short the time spent, and let them deliver projects much faster.

  • Invalid Syntax in Python: Common Reasons for SyntaxError

    Python is known for its simple syntax. However, when you’re learning Python for the first time or when you’ve come to Python with a solid background in another programming language, you may run into some things that Python doesn’t allow. If you’ve ever received a SyntaxError when trying to run your Python code, then this guide can help you. Throughout this tutorial, you’ll see common examples of invalid syntax in Python and learn how to resolve the issue.

  • Scraping dynamic websites using Scraper API and Python

    In the last post of scraping series, I showed you how you can use Scraper API to scrape websites that use proxies hence your chance of getting blocked is reduced. Today I am going to show how you can use Scraper API to scrape websites that are using AJAX to render data with the help of JavaScript, Single Page Applications(SPAs) or scraping websites using frameworks like ReactJS, AngularJS or VueJS.

    I will be working on the same code I had written in the introductory post. Let's work on a simple example. There is a website that tells your IP, called HttpBin. If you load via browser it will tell your real IP.

  • Registration for PyCon US 2020 is open!

    We are excited to announce the opening of PyCon US 2020 registration. The registration site has been updated, tweaked, and tested all in the effort to provide you a seamless experience.

    The new system will allow you to access, view, and add to your current registration. You can book and view hotel reservations and request changes if needed right through your dashboard.

  • The Incredible Disaster of Python 3

    I have long noted issues with Python 3?s bytes/str separation, which is designed to have a type ?bytes? that is a simple list of 8-bit characters, and ?str? which is a Unicode string. After apps started using Python 3, I started noticing issues: they couldn?t open filenames that were in ISO-8859-1, gpodder couldn?t download podcasts with 8-bit characters in their title, etc. I have files on my system dating back to well before widespread Unicode support in Linux.

    Due to both upstream and Debian deprecation of Python 2, I have been working to port pygopherd to Python 3. I was not looking forward to this task. It turns out that the string/byte types in Python 3 are even more of a disaster than I had at first realized.

    [...]

    On POSIX platforms such as Unix, a filename consists of one or more 8-bit bytes, which may be any 8-bit value other than 0x00 or 0x2F (‘/’). So a file named “test\xf7.txt” is perfectly acceptable on a Linux system, and in ISO-8859-1, that filename would contain the division sign ÷. Any language that can’t process valid filenames has serious bugs – and Python is littered with these bugs.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
