Few weeks ago in the late night, my friend asked me, where do I take the energy. He knows I have work, couple of sides projects and from time to time I try to write here some post. Is it some kind of a coffee? Or something else? I didn’t know how to answer, but I was thinking about it during a walk.

I needed to create a simple server, that would have one “public” route /login and other routes are available only for users with valid JWT token.

That means, the user is allowed to log into the system and then get any data from it. If he is not logged in and he tries to get some data, he only get an error message and 401 ( Unauthorized ) status code will be returned.

This post describes how to make HTTP GET and POST request on server. I will use httpbin server for testing. It returns you everything you send there : query params, post data, headers, etc.

Maybe you know the situation when you deploy some page, check it fastly and go away from the office feeling good about your job done. Then a colleague calls you and you hear “What did you do? It is not working!”.

Little story about my two hard and nervous days. Problems with NPM, fighting with Node and Linux, reading about Yarn. Wrote it down while sitting in front of the computer and thinking about nothing and everything at the same time, i.e. relaxing.

If you know what is Bactracking, you sure know about Eight Queens problem – how to place eight queens on an 8×8 chessboard. I found nice solution using bitwise operations which counts all solutions for any given size.

When you try to use two ( or more ) WordPress sites with one shared database, you will have problem to access the pages except the original one. WordPress knows what should be its URL and when it does not match with the request, it redirects you. Fortunately, there is an easy “hack” for this to make it work.

You know something worked properly a few days ago and now it is broken? Or maybe there is a new feature and you don’t know when it was added and what was changed? You can use this command and search in history of git. It is easy and fast.

I am playing a little bit with PHP micro framework Slim and javascript Backbone.js. Therefor I created two separate projects with URLs : mywebapp.dev for front-end ( Backbone.js ) and api.mywebapp.dev for back-end ( Slim ). The problem occurred nearly immediately : Cross-Origin Resource Sharing ( CORS ).

Collection of programmer’s jokes like various bug reports or types of code, then a few comments and in the end programming languages which are at least weird. Of course you will know some or most of them but I wanted to have them here, so I don’t need to seek them.
