Recently I decided to set up a Pi-hole installation on my local network. Initially I was going to use a Raspberry Pi 3 B+ but the company I work for was replacing all the PCs and I was able to get my hands on one of them.
Pi-hole is a simple tool which can be configured to handle the DNS of all the devices on a network. It can be installed on a linux environment and is also available as a docker image. Basically it will check any DNS queries against various blacklists and block queries that match ad networks or tracking domains. The end result is that you get a browsing experience without advertisements and user tracking. Pi-hole is configurable and you can whitelist domains or even devices on the network if you would like. The admin interface shown in the image of this post shows the dashboard which gives a nice overview of queries that go through Pi-hole.
I recently stumbled across a tweet by Melvin Davis on Twitter where he mentioned a simple tool that he had created using Go that instantly sends a Slack invite when an email is entered. This allows us to make a public slack community that anyone can join.
In my previous post I wrote a guide on how to post a simple Slack message using a bot with PHP. Now we will do the same thing but instead with Go. I have also decided to send a json request instead of a form-url encoded request like we did with PHP. There are some differences, let’s take a look.
I have done a lot of work with slack bots in the past both professionally and in my spare time. In the past I build a plugin for WHMCS called WHMCS Slack which was originally a paid addon but is now open source and available for free on Github. This post is a first part in a series of posts i would like to write about both Go and PHP and how we can use these programming languages to create useful bots for Slack.
It’s possible to create bots for your Slack channels and workspaces via custom integrations. First you will need to create a bot for your Slack workspace. To do this you need permissions to add a custom configuration. Simply go to your workspace url and add admin at the end as shown in the picture
A Quick Disclaimer: I'm a programmer and have very little experience trading. Please do your own research before using the algorithm I create for the cryptocurrency trading bot or any other algorithm. Only trade with money you can afford to lose.
In this guide I will show you how to create a cryptocurrency trading bot with Go. I highly recommend an IDE such as Goland but you can use a simple text editor if you would like. Feel free to take a look at my guide on how to develop with Go on Linux if you don’t have Go installed.
I stumbled across a scraper and crawler framework written in Go called Colly. Colly makes it really easy to scrape content from web pages with it’s fast speed and easy interface. I have always been interested in web scrapers ever since I did a project for my university studies and you can read about that project here. Before continuing, please note that scraping of websites is not always allowed and sometimes even illegal. In the guide below we will be parsing this blog, GoPHP.io.
