In this tutorial, we will explore the conversion of Python scripts to Windows executable files in four simple steps. Although there are many ways to do it, we'll be covering, according to popular opinion, the simplest one so far.
pdfsandwich generates "sandwich" OCR pdf files, i.e. pdf files which contain only images (no text) will be processed by optical character recognition (OCR) and the text will be added to each page invisibly "behind" the images.
pdfsandwich is a command line tool which is supposed to be useful to OCR scanned books or journals. It is able to recognize the page layout even for multicolumn text.
Essentially, pdfsandwich is a wrapper script which calls the following binaries: unpaper (since version 0.0.9), convert, gs, hocr2pdf (for tesseract prior to version 3.03), and tesseract. It is known to run on Unix systems and has been tested on Linux and MacOS X. It supports parallel processing on multiprocessor systems.
While pdfsandwich works with any version of tesseract from version 3.0 on, tesseract 3.03 or later is recommended for best performance. By default, pdfsandwich runs unpaper to enhance the readability of scanned pages and to improve OCR. For instance, slightly rotated pages are automatically straightened and dark edges removed. For optimally scanned pdf files, this can be switched off by option -nopreproc to speed up processing.
utf8mb4In this blog post, we’ll look at options for migrating database charsets to utf8mb4.
Migrating charsets, in my opinion, is one of the most tedious tasks in a DBA’s life. There are so many things involved that can screw up our data, making it work is always hard. Sometimes what seems like a trivial task can become a nightmare very easily, and keeps us working for longer than expected.
