Jizera Mountains, edition 2019

Jizera Mountains 2019

I visited Jizera Mountains again in this year. It was great time with a lot of hard cycling – not 100 km, but more that 2000 m uphill. Ufff, it was difficult, but amazing. I made a lot of personal records in many segments on Strava. Yep, it wasn’t most important, but it always something good. When next time? Maybe this year? Not sure, but want visit Jizera again! One info: tubeless saves me this time, but I disovered this after went back to home. I will wrote about that in one of next posts.

MongoDB – Natural sort

One of the most common problems with databases are sorting. Let’s see an simple example: we use MySQL/MariaDB and have table with some data. We want to sort this data. Everything is ok if we use only values in the same type in field, for example numeric (maybe some amount?), strings (titles), dates, keys etc. But what if field is custom, user-typed data and may contain many types? In that case, we have big problem, because standard sorting is not enought, it will not work. Example, value: “11”, “1”, “2”, “3”, “2a” will be sorted in order: 1, 11, 2, 2a, 3, not as we expected i.e. 1, 2, 2a, 3, 11. The solution is to use natural sorting.

Small story about and life decisions and cheese

Cheese

It’s very small story based on one part of one Polish book. Imagine, that there is a local shop with thousands kinds of cheese. You are shopping in this store every day. And every fuc*** day in your life, you choose gouda cheese. Always, every time, your whole life.

Imagine, you are dying. Will you happy knowing, that every day you was secure, you made secure, proven choice? Or maybe you will regret all these, wasted days?

Bryton Rider 530 – Review

Bryton Rider 530

As a very active cyclist, I use computer bike. Tried many solutions during last year and can say something about that. First was standard, digital Sigma, but without any connections, any synchronization etc. It was just simple, wireless computer bike with speed and cadence sensors. Then I tried to use old Sony Xperia. It supports ANT+, it’s small and can work some time on battery. Good? Not exactly, it was terrible. After that I use two watches – Garmin Vivoactive and Vivoactive HR after upgrade. Of course, both with special adapter. The last was Bryton, and this is small review of this computer bike.
