Fun fact: Windows XP had cool day 0 loophole that saved my my ass. Once I decided to explore new options and I stumbled upon new and cool feature: setting a password. The only issue with it was that I’ve forgotten it half an hour later. I already knew ‘admin’ word so I used it in hackerman style and I logged in and I was able to reverse old password. This loophole was patched with first service pack but I still giggle when I remind myself of that.

Polish C is also described as /t͡s/ (e.g. co /t͡sɔ/). According to wiki both are dental and voiceless although one is plosive and the other affricate. As I’ve read their descriptions on wiki, they made a lot of sense - /t͡s/ starts with a blockade of airway (just as /t/) but the air is released slightly differently thus making the difference in sound produced.

Looks weired but a sound of C and T has to be somehow connected, at least it feels like they are to me. Based on my experience, sound of Polish Ć and Czech Ť are transitional between Polish/Czech T/C. Proper linguist might put some more light on it than just my speculation.
