This is a story about an interview that I had with a Fortune 500 Tech Company some time ago. Background Back in the days I came across a Twitter profile of an employee claiming they were looking for a frontend developer. I usually do not apply for big companies, for a number of reasons. They u...

Write a plugin for Kong

Kong overview Over the last couple of week(end)s I’ve been playing with Kong - the open source API Gateway from the guys of Mashape. While I didn’t have any specific need to employ Kong, I’ve always heard good things about it and I wanted to give it a try. The first impressions were great; in ...

Programming ST devices with Visual Studio Code

I’ve been lately involved into embedded programming (nothing really serious and fancy, just basic stuff for an university exam), in particular with ST microdevices. Not sure about the others in the world, but at least here all professors use Windows as reference operating system, perhaps due t...

Solving the outside click problem

Today I would like to talk (and, hopefully, help you to solve) one of the problem that every frontend developer will (perhaps) deal with: closing on outside click Let’s say you have a drop down menu which will show its internal items when you click on it, and it has to be opened until an outside...

Creating a password hiding animation

Last week, while I was surfing the web, I find out Readme.io has a very interesting effect. If you go to their login page and place your mouse on the password field, the owl will hide its eyes, since it does not want to see your password. I found the thing very funny (and genial, to be honest). ...

API Design Lifecycle

On 25-29 October I spoke at FullStack conference, about callbacks and promises. Here is the video link!

Handling asynchronous code with callbacks forces us to build an unmanageable stacks of function calls, often leaving us buried beneath them. Is there a better way to handle this? Yes, with Promises. ES6 promises give...

Creating a FlipSwitch in Css

As frontend developer, I usually write a lot of stuff that runs in the browser. Anyway, most of the time, I write back-frontend code. It means that usually I do not fight with implementing UI components from scratch, and my CSS skills are usually limited to small modification. Not so long ago, I...

Do not use mega methods.

I have always (and you should too) hated the megamethods. A megamethod (name is my invention) is the typical antipattern where you have got an interface and a single method to implement, in which you should write everything. Sad to say, Microsoft is giving us just an example of this kind of int...
