A site where a tech geek writes about stuff
A little bit of a mini weekend project today as I wanted to put my Amazon Kindle to use when I'm not reading, and decided that the Kindle's "Experimental Browser" could be useful. How about an eInk digital clock... Note: I'm using Python for this project but similar results could be attained using JavaScript or Java … Continue reading Using a Kindle as an eInk Clock (Python)
Today I am having a quick play with the socket library in Python, and using it on my Rasperry Pi as a port scanner to check for vulnerabilities on devices connected to my home network. Yes, I know there are other tools available (such as nmap) that can do this but I wanted to see … Continue reading Creating A Port Scanner (Python / Raspberry Pi)
Imagine that you have a folder that you periodically check for a file (i.e. a network share where colleagues drop a file throughout the day) and when the file exists you have to move it and log when it was moved. I'm looking to tackle this today using Python. I've set myself the following outcomes … Continue reading Check For A File And Then Move It (Python)
Yesterday I introduced Selenium to my web scraping fun, see here: https://geektechstuff.com/2019/05/07/web-scraping-introducing-selenium-python/ if you missed it. Today I am going to use Selenium to interact with a website by: Opening a webpage Logging in Retrieving information from the page As much as I've enjoyed using Wikipedia in my previous examples (and if you too are … Continue reading Web Scraping: More Selenium & Ways To Interact With Websites (Python)
So far I have used Python with the requests library and beautifulsoup library. This had allowed me to GET and POST requests to web servers, and to parse results back in a more friendly way. Now I'm going to introduce Selenium. Selenium allows Python to interact with webpages by opening a web browser (e.g. FireFox, … Continue reading Web Scraping: Introducing Selenium (Python)
So far I have been scraping my website for a list of the divs, links and pictures that it contains, however I also want to interact with my site. Back in part 1 I briefly wrote about the GET command that is used when asking for data from a web page. The opposite of this … Continue reading Web Scraping: Interacting With Web Pages (Python)
Continuing on from Web Scraping Part 1. In this part I'm going to look at collecting the hyperlinks on a page. I have uploaded my work in Python to my GitHub, so that code examples are easier to follow: https://github.com/geektechdude/Python_Web_Scrapper def find_links(URL_INPUT): # returns all the hyperlink destinations on a page … Continue reading Web Scraping Part 2 (Python)
Web scraping can be a very useful way to extract data from websites but for anyone that has only viewed the web with a browser they can seem like magic. For example, here is http://www.geektechstuff.com viewed via a web browser: And here is http://www.geektechstuff.com when the HTML is read by Python: The majority of people … Continue reading Web Scraping Part 1 (Python)
Today I received a phone call and SMS text message that a flood alert had become active for the area I live in. After making preparations incase the alert severity increased I got to thinking; is there a better way to be warned about potential floods? One (quick) Google search later and I found that … Continue reading UK Flood Alert / Flood Data (Python)
I take it for granted that when I look at a picture I can identify what the items in the picture are. However, as a baby I could not and as a young child I would probably struggle with non-every day objects in a picture. Computers are at a point in their development where they … Continue reading Cognitive Computer Vision (Azure / Python)
