Afternoon Dancing

I wrote about the need for new types of salsa events and then I said let’s dance during the day without waiting! I did it. I was dancing only during the day at Šibenik, Berlin marathon and Heidelberg marathon. It works! For me, it’s amazing. A lot is …

Zápisky z cest: Berlín, vol. 2

Od té doby, co tancuji salsu a objíždím všemožné salsa festivaly, navštěvuji různá místa opakovaně. Bohužel čím dál častěji i jen z rychlíku. Víc tancuji a do města se podívám jen na chvíli omrknout hlavní turistická lákadla. Například loni jsem byl v…

Should You Buy Organic Food?

Short answer: it depends. But usually, not really. The long answer is, well, yeah, longer. :-) I actually haven’t cared much about food. I was just eating what was available. I call it a seafood diet: I eat what I see. Which is more fun when it’s not…

Open Source Responsibilities

I see two opinions. One: Author of the open source project is God and should be treated accordingly. People should be very thankful and very polite. If they want something, they should try as hard as possible. Dive into the code and provide at least…

We Live in Awesome Time!

Around us are many complaining people. Complaining how everything is much worse than years ago. Or how nothing is working. It’s not true. Don’t listen to them. We live in a very good time. Definitely, it could be better and there are many places which…

Science Channels

I watch several science channels and I was thinking I could share my list with others. :-) 3Blue1Brown Videos explaining difficult mathematical problems. Grant Sanderson is doing a great job to explain them simply. APOD Sorry, not a channel actually…

Salsa Calendar

I created salsa-calendar.com. A website which shows all salsa events around you or location you are interested in. With a clean design, simple, mobile friendly, all perfect. The most important part was automation. People are not good at filling forms…

Importance of blogs

Social networks helped a lot to connect all of us together. We can keep in touch even when we move to another city or country or during traveling or simply always. But… We got used to use social networks too much and put our content there. Which is a…

Deployment of Python apps

Python is very good language. It’s easy to learn, easy to use, with rich standard library and even richer library of 3rd party authors. Python is available everywhere and can be used almost for any task. But Python has also some problems. One of the…

Brief history of time

In case you want to learn something what is not easy to read, but interesting in the same time, I can recommend book Brief history of time by Stephen Hawking. I learned a lot about our universe and time. And even more I learned how much we don’t know …

Relationships and salsa

Salsa is a special place. Non-dancing people have problems to understand that. They are afraid their dancing soul mate is cheating on them. I don’t blame them. :-) Not because we do. Well, of course, there will always be someone like that. But because…

Nginx X-Accel explained

My team was working on CMS solution based on Django and we needed to have private files. Those files are also video files which we would like to stream to HTML5 player. Problem was, Django is not nginx or apache. It's even wrong to want it. We were sad…

T. G. Masaryk

I read mostly educational books which I don't read cover to cover, word by word. My reading is probably more scanning than reading. It's very good for this kind of books (as you only read when you don't understand or it doesn't match what you expect to…

Cute features

I produced a lot of code. A lot. I tried very hard to make all that code nice. Several times I was doing some cute features. Parts of the code which are not needed for the required result, but feels right. Or cool. Many times in those cases I regretted…

Tale of Two Brains

I wanted to be alone. But one girl disagree with me. She is trying very hard so I can love her. She is using a lot of dark magic! Many of them are explained in the following seminar. It's very good seminar. I'm not sure why she wanted to watch …

Rewrite stuff

If you want to learn a programming language or concept or framework, rewrite stuff. It's simple as that. I started with HTML. Then I discovered CSS, I rewrote my stuff. Then I learned PHP, I rewrote it again. PHP imports, again. Database. JavaScript…

Zápisky z cest: Paříž

Den první Organizace Francouzům moc nejde. Spíš vůbec nejde. Jejich salsa festival je nejvíc zmatený s nejvíce technickými problémy, co jsem zažil. Už od vstupu do hotelu nebylo jasné, kam jít, a tahle nejasnost se táhla celým festivalem. Stejně tak to…

Let's dance during the day

Last week I wrote about the need for new types of salsa events to have better diversity. To have more amazing places to learn and even more awesome places for social dancing. Problem is, it's not going to happen anytime soon. When I discuss this topic…

I was thinking how I could help the World if I would be sent back in time. Let's say I would invent a time machine by accident and send myself 100 years back. Or 200 years. Or even a thousand years back. Would I be even able to survive at …

We need new types of salsa events

Not long ago I wrote about how I see salsa community. It's a good idea to read it first if you haven't already. I will wait. :-) I said on2 community is kind of serious competitive VIP community. In a feedback, few people agreed, more had some issue…

Chrome is new IE6

I just realized that on my personal device I have only Chrome. I mean, not installed only Chrome, but sometimes I cannot even install anything else. I have Android and two Chromebooks. That's it. When I created app for salsa dancers, salsa-calendar.com,…

How I see salsa community

I'm shortly in salsa community (four years now), so, please, if you know more, feel free to correct me. Anyway, even if something is not 100 % correct, this is how it feels to me. To me, on2 salsa dancer located in Europe. Salsa community has two main…

Galactic Dangerous (im)PRobability

25th of May. The celebration of Towel Day since 2001 and GDPR, regulation in EU law on data protection, since today. I would start with the phrase on the cover of The Hitchhiker's Guide to the Galaxy: DON'T PANIC! It's not going to be bad. Definitely…

Zápisky z cest: Irsko

Den první Dublin. Už od příletu na mne dýchl svou irštinou, irskou angličtinou a stejně tak štiplavým počasím. Sotva jsem udělal krok z letištní haly, nastal jeden zmatek za druhým. Zjistit kterým autobusem se dostat do města není vůbec snadné. Ani když…

I'm white hetero men around 30, should I be worried?

We, as humanity, don't accept women well. We are a racist. We ignore old people. Young ones as well. We don't support minorities. We refuse to see working gay family. We hate other's religion. And political opinions. … We should fix all of that. We are…

Zápisky z cest: Itálie

Den první Stejně jako loni, i letos vyrážím na Mamboland. Jedinou změna je, že letenku nemám do Milána, ale do Benátek. Abych zůstal hodným přítelem, vzal jsem s sebou na začátek cesty i Lenku, kterou „deptám“ už od začátku cesty. Například jsme neměli…

Google Assistant 2018

What's wrong with salsa festivals

I attended many salsa festivals in last two years and I'm already getting bored of them. I'm starting to prefer smaller events in the usual time zone. Do you want to know why? Because of… poor organization. In Czech we have a famous joke from one play…

Zápisky z cest: Berlín

Do Berlína jsme jeli na salsa festival vlakem. ECčkem, kde jsme měli pohodlí, cestu si mohli krátit v jídelním voze a nemuseli v pátek večer někde stát v koloně. Protože jsme stáli v Drážďanech na nádraží. O den dřív byla v Německu neskutečná vichřice,…
