Three years ago, I created a Python extension module for Dynamsoft Barcode Reader C/C++ SDK. The code skeleton has never been changed until recently the SDK updated to v7.0. In the latest barcode SDK, besides the values of barcode symbologies, there are more constant variables needed to be predefined. The original Python barcode extension is initialized only with some methods, and now I have to add some object members. The article shares the code I’ve refactored in order to add Python object members.
Links is one of the critical SEO factors for a Website. When creating or re-designing some pages, we cannot ignore Website audit especially in terms of finding and tracking broken links regularly. Although there are many online tools, it is still worth learning and implementing such a tool ourselves for fun. To simplify the programming complexity, I decided to use Python. With powerful Python libraries, it is fairly easy to crawl Web pages, parse HTML elements and check server response code.
Plenty of enterprises allocate static IPs and gateways to employees’ devices for better network management. For example, limiting the internet connection speed, monitoring intranet activities and so on. In my company, the network administrator sets up two gateways for accessing different broadband services. During my working time, I often need to switch the gateways to obtain better connection speed. Is there any good tool for dynamically changing gateways based on network speed? With the question, I spend some time googling relevant information and finally find out a solution in Python. Let’s take a glimpse of how to make it.
