The real tough guys do not use mudguards in the bike, right? It’s not true. If we go for sport, of course they will be disturbed, but in many cases they are a rescue not only for us, cyclists but also for our equipment. Riding in the mud is not pleasant, just like spending time mainly cleaning the bike instead of actual riding. In the autumn, I decided to fight with bad weather and bought a mudguards set – Roadracer mk3 from Cud. The choice was not easy, because I use cyclocross bike, so assembly would not be the easiest, and the range of tires used was quite wide. After all, I think it was great solution.
The basic question is: why should we use this type of library and why not use the float type instead? The problem is that computers are not able (and have never been) to handle floating point values with real accuracy. While for some insignificant data this should not be a problem, in the case of recalculating the amounts of money-related transactions, it is already a serious concern. This library frees us from issues related to currency operations, storing them (or just preparing for it), adding or converting. All this without fear about lack of precision.
My cyclocross bike has been equipped with Shimano WH-RX05 wheels. Nice and comfort set for wide range of usage. But… I decided to buy new set and chose Daveo – polish company, that creates custom-made wheels sets. New wheels use DT Swiss parts. I have tested them for about last two thousand kilometers and I think it’s time to share my experiences. Short version is: yes, I can recommend custom-made wheels, they are worth the money and Daveo has made great job. Need details? Let’s read!
I must sometimes modify images and PDF documents in PHP. Prepare them to display after user upload, prepare for database, fix dimensions or many other things. Of course we can use native PHP functions, but it’s very slow. Better option is to use external libs like convert (ImageMagick) and Ghostscript. Today I have some useful convert commands – it’s “list to remember” for me, but maybe also you will find someting nice? This post is short, because I paste only commands and very short description.
