HaaS: Honeypot as a Service

My team at CZ.NIC finally introduces a stable version of HaaS, Honeypot as a Service. Who knows Czech can read it in an official blog post. For non Czech readers, CZ.NIC is mainly known for Czech domain registry, but does much more. For example secure…

Dancers, don't be sorry

Well, be sorry. Of course when you hit or step on someone, apologise. Or when you refuse to dance with someone, it's also better to say no with sorry than without it. But don't feel bad at all in cases you just didn't catch some move. It's totally all…

Django CSRF bug

We had this problem: our application worked well on desktop but on phone any action had CSRF problem. Mm, strange. Soon we discovered it's problem only with Android. Later we were sure it's only Chrome on Android. Even stranger! Next step we did was to…

Can you help with a political question?

Ok, so I have those struggles. I think I'm not alone. Actually, I know I'm not. Let's start with a little bit different question. In how many fields anyone could be an expert? My personal feeling is like about three, but the average will be definitely…

Why I don't trust recommendation systems

I liked Google Now. Liked. With the new Android it's changed and isn't very useful anymore. Before, you could just swipe to the left on your home screen and see all important stuff. Like how much time it takes you to go to work right now. Or when is…

How Twitter support works

I had problem to log in into my Twitter account because I couldn't get SMS code so I sent them message about that. They responded: Hello, Thanks for writing in. Many people who have reported issues with login verification have found the following tips…

Zápisky z cest: Šibenik

Už jsem tu jednou psal o návštěvě Chorvatka, to bylo s cílem týden se plachtit na vodě. Chorvatsko mne hodně překvapilo, ale stále mne neláká jeho návštěva jako taková. Přesto jsem tam byl už třikrát, po druhé a po třetí v Šibeniku kvůli skvělému salsa…

Whisky I like

I will not give you a professional analysis of whiskies. I'm really bad at describing the flavor of food and drinks. Take it just as my few notes which can maybe help you to find something new you could also like. Let's start with something more soft…

Open letter to salsa organizers

Dear organizers, I like to travel very much. It's amazing that I can have dancing as an excuse to go so often. Two-in-one! Actually, it's three-in-one. I dance for awhile now so it means I travel more because of people I can see there than because of…

It doesn't have to be scrum

I have a feeling that when there is something about agile, it means scrum or kanban. But it's not just that. It's definitely one way how to be agile, but it's not a synonym. The most important thing about being agile is communication. You can actually…

Movie by Artificial Inteligence

Not long ago I was writing here about how I'm not afraid of artificial intelligence. Then my colleague sent me this video of how AI created a sci-fi screenplay… I'm going to add just one note: I'm sure one day we (as humanity) will look back to this…

Salsa marathons

I think that the classic concept of salsa festivals with a lot of workshops of all different dances during the day and parties over night are not ideal. I see two types of people: Those who want to learn something new. But I don't see much of value in…

Zápisky z cest: Londýn, vol. 2, 3 & 4

Trocha kontextu: pracovní cesty. První Kancelář je na místě, kde jsem v roce 2015 šel naposledy před cestou domů! Business oblast se spoustou kravaťáků. Jenom kravaťáci, téměř. S mým sáčkem jsem moc nevyčníval. Vlastně jo, ale opačně než doma. Druhý den…

Makefile with Python

I like when everything is easy. I like to open some repository and in as few steps as possible to run example and see how it works. Ideally just call run and that's it. Python is great, Python makes a lot of things very easy. But tooling around, mostly…

I'm not afraid of AI

Every useful program has three parts. Input and algorithm which produce some output. Classic programming means that you write the algorithm which can convert your input into output you want. You are the master and the code by itself cannot think because…

The Three Dancers

In the last months I discovered one interesting thing. I don't care about big salsa festivals or any other events anymore. Well, I was never interested in any crowded event, but I wanted to have a lot of good dance partners so I can enjoy the night. Not…

Infinite feeds

Years ago, there was no Internet. You could read news only from newspapers and books. Both has the end and you have to stop. After you finished newspaper, you had to wait a day or week or even month for the new fresh one. During that waiting you just…

Technology is double-edged sword

Technology should help us, right? We should be more productive than years ago before technology. Everything should be better, faster, smoother. But it isn't. Actually, it's still the same, kind of. Nowadays everything is fast. You can say hi to anyone,…

Česká taneční salsa a bachata scéna

Lehce závidím mimo pražským. Aspoň mám představu, že v těch menších městech je to tak malé, že tam nevzniká to, co vzniká v Praze. V Praze to je totiž politika. Až válka. Možná častěji to připomíná tu válku. Víte, občas člověk potřebuje skoro dva pasy…

South Park

It's been awhile I wanted to watch South Park. Every kid want's to watch animated shows, even more when it's vulgar, right? :-) Well, my parents didn't allow me to wait until late hours to see it and later on, when I could, I didn't care. Actually, I…

Jak vznikají zápisky z cest

Na jedné z mých prvních cest jsem narazil na Brity, kteří byli už rok na cestě kolem světa a měli ještě půl roku před sebou po Americe. Já, jakožto cestovatel začátečník, jsem byl hrozně zvědav na jejich postřehy, příběhy, všechno. Ale neřekli mi skoro…

Zápisky z cest: New York

Upozornění: Nejsou fotky! :-O Téměř; kvůli rozbitému telefonu jsem přišel o většinu svých fotek. Zato e-maily se spoustou textu o New Yorku a salse mi zůstaly. Všechny jsem sem přepsal. Omlouvám se za délku! Den první New York je hrozné místo. Nelíbí se…

Only two notebooks worth to buy

I don't understand why it's hard to find good notebook. Actually only usable device (at least for me) is Chromebook or Mac. Anything else is just piece of s… ehm, not good piece. After years I have again Dell. Very good one. But I have problems to use…

Stereotype is good

The world is composed by patterns. You can see them everywhere. Probably also that's why people are better with stereotype than without it. I think that people cannot even live without stereotype. You know, it's very exhausting to get up every day at…

Mamboland: the best salsa festival

There is always some dance festival. No one is able to visit them all. You need to choose some… which is hard. I soon realized dancing isn't about variations and I stopped attending workshops. Not entirely but now I attend only few of them. Because it…

Open source sucks

Yes, you heard me. It sucks. I like open source. I use open source. I write open sources. I contribute to open source. And I will continue to do that. Anyway, open source sucks. There are two types of open source. Let's say, kind of, back-end and…

Why do you dance?

Sometimes, I'm kind of sad when I look at dance floor. I'm curious, why do you dance actually? Personally, I dance because I cannot sit when I hear good music. Because now I have a lot of friends who dance and I want to hang out with them. Also because…

Nexus 5x vs. Pixel

My old Nexus 5 was broken and I needed new one. It was just few weeks after Pixel was released so I had tough question: go for Nexus 5x with discount or go for Pixel? There was really big pro for Nexus: the price. 8 vs. 22 thousand (CZK) is a big…

Zápisky z cest: Lublaň

Aneb další vtipná historka do sbírky. Vše začalo na letišti. Letěl jsem domů ze salsa festivalu s Tomášem a Eugenem. Při čekání na letadlo jsme rozebírali českou salsa scénu a kdo jak tancuje on2. Vášnivě jsme debatovali i při nástupu do autobusu,…

How I competed at Bachata Stars

Twice. By mistake. More than a year ago Alexej invited me to bachata competition called Bachata Stars. A competition which is open for everyone and the winner is going to the world championship. At that time I was dancing bachata only for a few months,…
