Convert e-books to txt

-

If you want to convert e-books to plain text (txt) on linux or other Unix-like systems, here are some command-line utilities that you can use along with their terminal commands:

File type Text conversion utilities Examples
.djvu 1. djvutxt
2. ebook-convert		 1. djvutxt input.djvu output.txt
2. ebook-convert input.djvu output.txt
.epub 1. epub2txt
2. ebook-convert
3. unzip		 1. epub2txt input.epub > output.txt
2. ebook-convert input.epub output.txt
3. unzip -c input.epub > output.txt
.doc 1. catdoc
2. textutil (macOS)
3. ebook-convert		 1. catdoc input.doc > output.txt
2. textutil -convert txt input.doc -output output.txt
3. ebook-convert input.doc output.txt
.pdf1. pdftotext
2. ebook-convert		 1. pdftotext input.pdf output.txt
2. ebook-convert input.pdf output.txt

NOTES:
  • There is a caveat for unzip: the generated output file will also include HTML tags since epubs are zipped HTML files.  That's why I put it in 3rd position in case that you want a quick and dirty solution.
  • ebook-convert is a utility from the e-book library manager calibre that can support many other e-book formats for text conversion.
  • textutil can take as input files:  txt, html, rtf, rtfd, doc, wordml, or webarchive

Install the MAMP (Mac, Apache, MySQL, PHP) stack

-
Image
There are two ways that you could install ( freely ) the whole MAMP stack: installing the MAMP (version 4.5) software bundle is the easiest way since it is a one-click-solution for setting up a personal webserver install each components (Apache, MySQL, and PHP) separately. This second method consists in installing Apache and PHP with Homebrew, and MySQL with the  package Installer . It is the hardest method but it enables you more control over the installation process, e.g you can install specific versions of each components, or install extra PHP extensions. NOTE:  MAMP 4.5, Apache 2.4.33, MySQL 8.0.11, PHP 7.2.7, and phpMyAdmin 4.8.2 are installed in the following tutorial Contents 1. Method 1: install the MAMP software bundle 2. Method 2: install each components (Apache, MySQL, and PHP) separately      2.1 Apache+PHP           2.1.1 Install Apache+PHP           2.1.2  Change Apache's default ports           2.1.3  Start the Apache server           2.1

Deactivate conda's base environment on startup

-
Image
When opening a terminal session, conda activates the base environment by default. If you want to prevent this default behaviour, you have three ways: Trick #1  :  Set the auto_activate_base parameter to false Trick #2  : Add conda deactivate in your bash configuration file Trick #3  :  Comment out some part of the conda initialisation code block in your bash configuration file NOTES: I'm working with  conda version 4.7.5 and  miniconda3 (it should also work with anaconda ). These tricks also worked with  conda version 4.6.14 After installing conda 4.7, conda added this block of code in my ~/.bash_profile : This is the block of code that we will modify in the following tricks Trick #1: set auto_activate_base  to false Per conda's instructions, "if you'd prefer that conda's base environment not be activated on startup, set the auto_activate_base parameter to false". Thus, enter the following command in a terminal: conda config --set

Product review: SMONET wireless security camera system

-
Image
I bought a security camera system from SMONET which consists of 4 wireless [1] bullet IP cameras with night vision: each camera comes with its power adapter [2] . There is an optional Ethernet port on each camera. The camera has an image resolution of 1280*960P . An NVR (Network Video Recorder) system: it comes with its power adapter, a mouse, and an Ethernet cable to connect the NVR to a router. In the Amazon product page  (product description section), they talk about 2 USB2.0 Port but my NVR only has 1 USB2.0 Port in the back, and you can also see it in the user manual  (page 3) that there is only one USB2.0 Port in the back of the NVR. This NVR doesn't come with a hard drive; you have to buy it separately. It is important to stress that if you plan on having a robust security camera system that is very reliable and secure 24 hours a day, 7 days a week, you should opt for a wired security camera system. This wireless security camera system allows you to change the w
