Summary​

On 2019-08-02 we at bitcrowd discovered a security vulnerability in simple_form. simple_form is one of the go-to ways to easily handle HTML forms in Ruby on Rails. The security issue allows arbitrary code execution in the worst case, but at least has potential for data corruption or DOS attacks. This security issue was responsibly disclosed by bitcrowd. Find details about the timeline of the events and a more detailed description below.

If you add a new file to your code which you want to add to git later, you can show that intent early with git add --intent-to-add. This is quite useful when want to add new files to the index (so you don’t forget about them later), but you’re still working on them and don’t want to add the content just yet 🥳

Both, SASS and CSS support variables, and of course they are not the same:

  • SASS variables get compiled into actual values into final CSS files.
  • CSS variables can be used as variables in the browser.

The first time I found out about eurucamp was during the euruko 2011. Some people talked about this “unconference” close to the venue that a few people had organized. The tickets for the euruko had been sold out too quickly and everyone who could not buy one was invited to meet there instead. At that euruko I gave my first real talk and because of that I was way too nervous to take the U8 to visit them. I should have done it.

React is currently the hottest JavaScript framework out there. And shockingly it had no usergroup here in Berlin. But luckily this changed last week with the first meeting of React Berlin in our office.
