These days I had an interesting problem to solve. At work, on our staging environment, we have basic authorization. It works really well but for some older versions of Chrome we experienced a weird issue. The browser did not pass the authorization header. The app runs fine but as soon as it does a fetch request to a local endpoint the request fails with 401 not-authorized error. In the modern browsers that's not happening because the browser kinda knows that we came here with basic auth and automatically includes authorization: basic ... header.

I just recently moved my outset.ws domain to Zeit name servers. That's my 13 years old domain which I'm not using it anymore. It makes sense to point to krasimirtsonev.com. The thing is that I have an email which is used all over the net. I of course want to keep that email. And suddenly I wasn't able to receive messages to it. I started missing some very important emails. Like bills that have to be paid and GitHub notifications.

87% of my readers are using Chrome on desktop. This means that I have the luxury to care less about performance. However I just recently found that this blog has 56 (out of 100) points on Google's pagespeed test. That's not good. The report says that my Disqus comments are blocking the main thread for ~900ms. I want comments on my blog but I also want my users to reach to content as quickly as possible. So, after so many years using Disqus I decided to break with it and use something else.

Long long time ago in a kingdom far far away there was an app. The app was supported by the well known React and Redux families but there was a problem. It was damn slow. People started complaining and the app had to do something. It had to deliver its content quickly so it provides better user experience. Then the server-side rendering was born.

I recently finished watching Mr. Robot. If you didn’t check out the show please do. Last few days I felt like I’m hacking something. Just like Elliot in MR. Robot. This blog post is about fixing a weird bug. Really strange problem with a failing HTTP request.

There are few things which I'm thinking about last few months. I summarize them here. Initially, I started writing this article for the company which I'm working for - East Interactive. The material is not meant to teach. It just contains few thoughts of main and I hope that my colleagues will find it helpful.

I'm working on a year old application written in node. There is twitter streaming API implemented and it worked before a couple of months. These days we moved the site on another server and I found that it is not working anymore.

Ok, that was a long journey. I took an already build project and I had to make some changes. It's a complex system involving flex applications, nodejs and a mobile site. Before to start making changes I had to setup the project and make it work on my local machine. I spend few days doing this. At the end I successfully compile the flex application and made the necessary corrections. I uploaded the new swf file and of course it didn't work.

Ok, I should admit that mod_rewrite and regular expressions are not my strongest part. Today - as every other day I realize how little knowledge I have. Actually it's good to have such moments. I lost almost two hours fighting with a really really simple mod_rewrite rule in my .htaccess file.

Let's say that you have an access to remote server which has Git installed. A trivial case if you use unix based OS. But what if you use Windows :)

Ajax is a powerful tool for loading new content or data asynchronously. The well known problem is that we can't make requests to other hosts. In other words if your code is located at aaa.com you can't load bbb.com/getData.php. There are several solutions available.

I successfully finished an interactive project for one of my clients. We did a great job and finally I had to install the system on their server. I received the FTP and MySQL information from their IT team, but when I uploaded all my files the site didn't work at the first time. The server didn't show any errors and I wasn't able to find out the problem.

Yesterday I received host name, user name and password for a MySQL server. I needed to export the data from it. I didn't have access to PHPMyAdmin, I tried to connect to the server by mysql.exe on my PC, but it didn't work. And then I found really good solution - PHPMyAdmin in only one php file. I launched it from my localhost and it works. So if you need to export data or just see it, use Adminer. I also uploaded the file on my server, you can download it from here.
