At our university there are still paper-based coding assignments in computer science classes. To make a step into the 21st century, we started developing Programming and Auto Evaluation Platform almost two years ago. We are now happy to anounce it to the public.

- Free and open source under AGPL
- Programming language agnostic
- Flexible auto-evaluation system based on Docker
- In-browser IDE for zero-setup coding exercises
- Integration with Learning Management Systems via LTI standard

We still have a large roadmap ahead of us but we are already running in production from the MVP on. We continuously field-test with actual students and would love to get other educational institutions on board. If you are interested in trying in trying it out, please get in touch with us!

The application is developed with Kotlin (Spring) in the backend and TypeScript (React) in the frontend. We are looking for contributors to make this a real community-driven project!

#  Fixit?

In my Fixit series I'll write about quick solutions to problems that I encounter every now and then.

## Problem

Brief: MySQL daemon fails to start

Details: So, I recently installed MariaDB (Community fork of MySQL) on my Manjaro system and when I started the system with: sudo systemctl start mysqld

This is the error I get:

`Job for mariadb.service failed because the control process exited with error code.`

Let's look at `journalctl -xe`:

`A start job for unit mariadb.service has finished with a failure.`

Not very helpful, let's look at mysqld's status with: `systemctl status mysqld`

`InnoDB: The innodb\_system data file 'ibdata1' must be writable`

Ah, there's the culprit mysql doesn't have write access to this file.

## Solution

A quick look at the man page and after some google searches the solution I came up with was simple:

`sudo chmod -R 777 /var/lib/mysql`

If you are facing any issues while running `mysql\_secure\_installation`, you can run `mysql\_upgrade -u root` to fix the permission issues.

There we go, we have solved another problem, stay tuned for more FIxits. 🧑‍💻 🕵️

Mconnect Product Image Flipper Extension for Magento 2
Published: 2020-08-28 11:26:50

One study found that 83% of the consumers responded saying that product images are the most influential when it comes to making a purchase decision. The difference between shopping online and on the physical store is that the later provides you the facility to see, feel, and look at the product which the former does not. So, all customers have to rely on the images of those products. All their purchase decisions are based on the available description of the product and pictures from different angles. But some might not reach on the product detail pages because they might leave store after seeing the product on listing pages. Therefore, you need a functionality that allows your customers to see different angle pictures or videos from product listing pages itself. 

Mconnect Product Image Flipper Extension for Magento 2 provides Magento store owners a facility to showcase the different images and videos of the product by hovering over them. The extension will change the main image of the product from the product listing pages with the secondary image or video. A flip effect takes place whenever a customer searches for products and hover over any of the product while still being on the listing page without going into a particular product page. The admin can simply upload flipper images from the backend catalog page. Also, the extension allows you to upload video or a link to an existing YouTube video. And the best thing about this is that it works with any theme and does not affect the page load time. 

Features of the Mconnect Product Image Flipper Extension for Magento 2:

The extension will automatically flip the image of the product once a customer hovers over it. 

You can show multiple angles of the product in image such front/back/side views.

It works well on the category page, or any product listing page.

Simple to upload any number of slip images or videos from the backend.

Also, the extension allows you to add YouTube videos as well.
 
When someone hovers over, the extension will flip the image horizontally or vertically, for convenience you can choose either of the ones.

Option to set a priority to showcase first an image or video if both are available. 

Works effortlessly with any of the Magento 2 themes. 

It does not affect the load time. The extension even helps in reducing the load time by rendering the page once image/video loads.

# Introduction

There are many reasons why you might want to create your personal [developer blog](https://devdojo.com/devblog). You might want to share your knowledge with your community, build a following, learn more by doing, and even get a better job.

Choosing the best blogging platform might be overwhelming when just getting started. You can choose between a WordPress blog or a custom-built site from scratch.

Both could be intimidating if you are just getting started or even if you just want to get up and running quickly without having to invest too much time.

In this tutorial, I will show you how to get your own blog with a custom domain name within 10 minutes completely for free!

# Getting started

In order to get started all you need is to sign up for a free account at the DevDojo website and hit the [Create my dev blog](https://devdojo.com/devblog) button:

# Setting up a domain name

Once you have your free DevDojo account and your DevBlog created, you can start with your blog configuration.

If you don't have a domain name yet, you can use the default subdomain username.devdojo.com instead.

However, if you have a domain name, you could use it as well. 

To do that you need to point your domain to [Cloudflare](https://www.cloudflare.com/), then add a CNAME record with Content set to: `username.devdojo.com`.

If you don't have a domain name yet, you could [get a free one as described in this tutorial here](https://devdojo.com/bobbyiliev/how-to-get-a-free-domain-name-for-your-laravel-project).

# Changing the theme

Under the `Themes` tab you will be able to choose a different theme that best matches your needs.

![Developer Blog theme](https://imgur.com/zLdv56R.png)

All themes were built using the Tailwind CSS.

Each theme comes with a light and dark mode as well!

# Adding pages

Under the `Pages` tab you will be able to add new pages, and again use markdown for the content of your pages:
