Using Parsel instead of Beautiful Soup for Web Scraping

Mon, 28 Nov 2022 00:00:00 +0000

Web scraping is an automated process to extract data from web page, and since Python is one the most popular programming languages it’s common to see people use it for doing web scraping tasks like me :)

For a long time, I have been using Beautiful Soup 4 to extract data from web pages’ HTML markup, it’s popular, easy, robust, and battle-tested library for navigating, searching, and modifying the DOM tree. But, recently I came across Parsel, another HTML parsing library that supports XPath selectors, which is missing in Beautiful Soup, and I was in need of using something that can extract data from HTML using XPath (rather than Scrapy, funny enough, later I knew that Scrapy uses Parsel under the hood :D), so I decided to get it a try.

There are many kinds of bugs you may face while programming, but without a doubt, ghost bugs are the worse!

I recently faced a weird problem while working on a freelance Selenium (A portable framework for testing web applications) project in Python which is: send_keys method is sending random wrong input. Here are the details of the problem, how did I debug it, and how I managed to fix after hours of investigating!

How to build a Project Treble GSI ROM from source?

Sat, 09 Jun 2018 00:00:00 +0000

Note: This guide is super old and some steps might be changed, please refer to the community edited guide for a more recent guide.

As you read this guide now I’ll assume you already have a previous knowledge about How to build android from source, so I won’t cover some points with too many basic details. So, let’s start:

What you’ll need:

A treble enabled device, basically all devices that come with Android 8.1 out of box support it.
A relatively recent 64-bit computer (Linux, OS X, or Windows) with a reasonable amount of RAM and about 100 GB of free storage (more if you enable ccache or build for multiple devices). The less RAM you have, the longer the build will take (aim for 8 GB or more). Using SSDs results in considerably faster build times than traditional hard drives.
A USB cable compatible with your device
A decent internet connection & reliable electricity
Some familiarity with basic Android operation and terminology. It would help if you’ve installed custom ROMs on other devices and are familiar with recovery. It may also be useful to know some basic command line concepts such as cd for “change directory”, the concept of directory hierarchies, that in Linux they are separated by /. etc.
