Sumár informácií pre začínajúcich “clubhouserov” na Slovensku, ktoré sa dajú poslať v jednej správe ako link.

Je treba brať na zreteľ, že aplikácia je vo vývoji (aj preto je len na pozvánky) a mnohé funkcie zatiaľ nie sú dotiahnuté, menovite napr. vyhľadávanie miestností.

Než niekomu pošleš pozvánku

  1. Nevyužitú pozvánku nevieš zrušiť a odvolať.
  2. Dávaj si pozor na preklepy v telefónnom čísle, chyba ťa bude stáť pozvánku. Poslanie pozvánky na číslo bez medzinárodnej predvoľby býval problém. Novšia verzia Clubhouse by si už s formátom čísla bez medzinárodnej predvoľby mala vedieť poradiť.
  3. Keď chceš niekoho pozvať, už ho nemusíš mať v kontaktoch. Kedysi tomu tak bolo a než sa dalo poslať pozvánku, musel/a si si ho pridať do kontaktov. …

I keep forgetting this every time. So let’s recap the steps necessary to set up basic ES6 project with Babel, ESLint, Browserslist and Flow.

Notes to take into consideration:

  1. This is a bare minimum set up;
  2. It does not include corejs, you need to provide browser polyfils in the final entry/bundle file of your final web project;
  3. Flow static type checking is optional, I just like to use it and with this setup it’s really straightforward;
  4. Structure of the project is:
    dist/ — destination where src/ is being transpiled into;
    flow/ — projct specific declarations of types, e.g. …

Ever wondered how to make such thing working right? Me too. So here’s how with none of the $ObjMap<T, F> utility obscurity.

It looks like is should work but it doesn’t. There are few mistakes in our basice assumptions.

tl;dr: Use Object.freeze() and $Exact<T> Flow type utility.

1. Type is not Exact

Defning object type in Flow is by default inexact. Making your object type $Exact<T> would force object to has only the properties/keys defined by the type. You can use short notation {|᠁|} or more explicit, which is always better,$Exact<{᠁}>:

Recently I switched from developing React Native apps back to developing websites. You know, due the corona and stuff. And I miss few things. More than a few things to be honest. But what I miss the most is the tooling, Flow in particular.

Flow is a static type checker. It checks the Flow type annotations embeded into Javascript code and bugs you with errors while you code before you even start the engines. That’s why it’s tagline states it’s a static type checker for JavaScript.

For the sake of brevity of reading from now on whenever I refer to Flow I mean code with Flow-flavoured annotations taking TypeScript into account. TypeScript and Flow have quite similar in type annotations at least for the basic primitive types. …

When the Fujifilm XT-3 camera came with an firmware update Ver.2.10 that allows us to shoot video files over 4GB file size limit I thought that that’s it. All of my problems should have magically be gone by now. Except I was wrong.

The release note states:

Recording over 4GB movie file as one file

Movie files are no longer split when the file reaches 4GB file size. The file is recorded as one file providing an SD memory card greater than 32GB is used (excludes 32GB) (*1).

That *1 mark means that there are few conditions however:

  1. You need SD memory cards bigger the 32 GB otherwise movie recording will continue without interruption when the file size reaches 4GB, however subsequent footage will be recorded to a separate file.
  2. You need to re-format SD memory cards before first use, and be sure…

This my first take on looking for a straightforward unified solution to responding to Keyboard open–change–hide events in React Native. There are great solutions that work great in some specific cases. But I’ve tried and failed to get them work great together.

This is the first article to cover this broad topic to invite others to share their experience. I am sharing mine together with some code samples. I am looking for your comments and thoughts.

The new “average”

Look at the list of the most used apps in the app stores. Most people have had experience with most of them. Those apps provide some of the best, if not the top user experience on mobile. That’s what they, I mean we all expect the same from your app.

  1. keep the content accessible while the keyboard is open;
  2. dismiss the keyboard interactively while scrolling down…

Victor, bench at the Kalemegdan, and Genex on the horizon

I was sixteen or so when I got a new mobile phone. Last one was stolen from me on the bus while chatting to a girl I liked and I got my eyes and ears just for her. One day I set the language preferences on the new phone to Serbian and never looked back. Many words were almost similar to Slovak, some resembled others. I still remember some.

Take “Šaljem poruku.” for example which means “Sending a message”. “Šaliť” or “šaliť sa” means to get crazy and have fun, or to do tricks. Usually kids “sa šalia” at the playground. “Ruka” means hand in Slovak. “Poruke” means having something close, withing the reach (of a hand). It still makes not much sense to me and most of the phrases had some quirky meanings too.

Fast forward. On July 5, 2018 I planned a short trip to Prague with short stop in Brno along the way. My plan was to attend some dance event, then hop on a morning…

You won’t notice. At first. You won’t notice that moment she comes. But after she comes, you will know. You will know and feel the difference. But not immediately and the reason will become obvious yet simple only later.

She is your home.

She is familiar. Like she didn’t had to come nor leave. Her touch is warm, her embrace tender. You won’t wonder what’s happening. It will feel all so natural.

That’s why you won’t notice.

She will stand in front of you and you won’t notice she came but you will pay full attention to her presense. Almost like she was there with you all the time. Nothing hits you. No smoke signals, no upfront notification, no grand manifestation. No fanfares.

She will simply be there.

You won’t loose your breath and your heart won’t start to…

I remind myself that I am here for limited amount of time. It is a good thing to do. I feel shivers down my spine every time I realize that.

There is this dialogue between the unconscious me and the introspective me that is constantly torpedoing the other one with questions and pushing my limits.

“Let’s turn it all upside down,” it said one day. “You are going to die tomorrow. But, you are given one last day.”

Now imagine this happens every single day just before you go to sleep.

Every. Single. Day.

You are given one more day to live.


How would you live your day if it worked that way? What would you change? What would you do differently?

When was the last time you said to…

I took a break. A break from me failing at what is the most precious — love.

This is not a post about 10 things I learned while I was being single nor an heroic ethos about how it transformed my shallow existence into something worth loving.


I am worth loving. I know that. And I want to feel close and intimate with a human being. I want to feel and share connection. It was always like that. It was so strong that I got myself into yet another dead end relationship more than few times in a row.

It got better in the end. …
