I received a book for Christmas, the author is Marie-Monique Robin and the title is “Our Daily Poison..”. This is perhaps the second book I read about the food business, the other one is “Salt Sugar and Fat” by Michael Moss, those books has strengthened my gut feeling that what we eat isn’t safe and […]
We all have our weak sides, areas of knowledge that are way too far from an acceptable level. What is an acceptable level then, is all a matter of what you do and what’s the purpose of your knowledge. Changing job or project is going to greatly influence what will be your skill set in […]
Sometime you really want a book, but you cannot find the damn book anywhere! This is the case of Competitive Programming 3, which friends of mine referred to me many times, so I decide to give him a try. First place where normally I look for books is A., but no luck there. Then I […]
Coming back to normality.
The last two weeks were pretty unusual, Magda moved to my apartment in Gdansk because finally she found a job here. She had her first day at work last week, at the beginning going to work was problematic since she knew nobody at the office which could pick her up and the only way to reach […]
Short summary of our holiday.
I’m back in Poland, with a bag full of wine, cheese and a good quantity of prosciutto! Watching out of my office window the first thought running in my mind is “How the hell can I live in a place so cold?!?”, from +20 to -2, from running under the sun in Santa Severa to walking to my […]
Ain’t I’m tired, I’m exhausted!
I wasn’t programming very much in the recent period, I’m still deep involved in my combinatorics book and in a couple of papers on the Ramsey Theory, additionality in the evening before I go to bed –or when I’m in the bed– I spent few time on my new book on text algorithms. Sometime I […]
Summary for the week.
This was a very long week! Most of my free time I was at the gym or on my combinatorics book learning fancy details about the pigeonhole principle, which is very simple but with large implications in problem solving. The pigeonhole principle basically say that if you want to put three pigeon in two holes, […]
The real keyboard.
Back in the days, when computer were used by real computer users and nobody knew what a mouse is, the preferred input device was also the only input device: The Keyboard! When the hipster revolution began back in the seventies/eighties, the proliferation of the mouse users increased dramatically, the keyboard was still the preferred computer input […]
A long weekend!
Hi all, This was a very long weekend, some friends along with my brother and cousin came to my house in Gdansk for my birthday, we had a party –or two– and we went out to the city. We had a great time and I’m very happy! I didn’t expect it to be someone in the weekend, […]
IO Stream performance.
Many of the competitive programming portals available on the web advice –for certain problems involving huge input reading or output printing– the user to avoid cin/cout in spite of printf/scanf: As input/output can reach huge size it is recommended to use fast input/output methods: for example, prefer to use scanf/printf instead of cin/cout in C++, prefer to use […]
