Shimano vs SRAM

Takúto otázku by som si položil, keby som si šiel kupovať nový bicykel podľa svojich predstáv. Nič také nehrozí, ale aj tak ma zaujímal hlavný rozdiel. Doteraz som jazdil a jazdím len na prevodoch od Shimana. Viacmenej som ani nikdy neuvažoval o inej sade. Odjakživa som považoval bicykle s Deore a vyššou sadou za čosi, na čom sa dá už poriadne jazdiť. Veď aj na mojom Altuse sa dá, ale je to trocha iná kategória. Stačila mi jedna jazda s Alivio-m, aby som vedel, že Altus je určený na jazdu do obchodu a späť.

Americká firma SRAM má okrem prevodových systémov pod sebou už aj Rock Shox, Avid, Truvativ. Skoro celý bicykel pod jednou značkou. Prednosťou SRAM-u je vraj pomer 1:1, čo znamená o koľko posuneme riadiacu páčku, o toľko sa posunie prehadzovač (napr.). Shimano používa pomer 2:1. Pomer 1:1 je vraj odolnejší a stálejší, pretože je jednoduchší. SRAM použil ako prvý grip shift, čo mne lezie na nervy. Takých ale bolo viacej, tak začal vyrábať aj páčky Attack. Veľa sa diskutuje o pevnosti zadného prehadzovača pri kazete. Ako sa správajú obidva systémy pri zjazde je dobre vidieť na tomto videu:



Tento problém u Shimana by mal byť vyriešený v sade 08. Tiež je otázne, či je na bicykli dobre napnutá reťaz. Celkovo sa dá povedať, že otázka výberu je len otázka vkusu. Veľmi rád by som si SRAM vyskúšal a porovnal s ekvivalentým systémom od Shimana. Jednotlivé časti sa vraj dajú kombinovať, ale to by som veľmi neriskoval.

Additional RAM to iMac and installation of some software and games

RAM upgrade

After Mac OS 9 updates I started to use this system. But after a short while I realized that I really need more RAM. It was almost impossible to work with more than one application. Therefore I was decided to buy 512 MB RAM.

I knew about one small shop with old computers on Favoritenstrasse (U6: between Taubstummengasse and Südtiroler Platz). I went there and asked about SDRAM PC100. Old but nice guy showed me some 512 MB modules for about 30 €. I didn't have so much money with me at that moment and I also wanted to visit that Mac shop once more. So I left the shop and forgot my umbrella there.

That Mac shop offered me the same kind of RAM for about 45-50 €. Hmm, .... No thanks. I went to my room and picked some money from bankomat. I returned to the computer shop and the seller offered me (except my umbrella - for free of course) one module for 24 €. It has not been tested yet. I have bought it and put in my iMac - and nothing happened. Bad, but I had to go to the school…

#covid19 in the Upper West Side

As of today, New York’s total death toll rose to nearly 3,000, double what it was only three days earlier. The total confirmed cases in the world is 1,141,190 and more than 57,000 of those are in New York City alone. The news is full of sad stories. My family and friends are asking me about the situation in the city on a daily basis. It must be shocking for them to watch the news aboutNew York. But, in fact, how is my life in the Upper West Side?

My last day of work before this lockdown period was March 16th. That day, I gave some data to my colleague, packed my desktop computer in my hiking backpack and walked the 20 blocks home. A lucky move, because a few days later, our institute officially closed their doors. Since then, Mia and I have lived and worked together in my/our apartment, which is around 20 square meters large (200 square feet), in the Upper West Side of Manhattan.

Since Mia and I started dating, we had a rule to live together only after our engagement. We both wanted t…

Windows 7 RC Ultimate on HP Compaq nx6110

I have never tried Vista on my laptop, because it is well suited for WinXP and I don't like Vista. But what if you can download the new Win 7 RC for free?

I'm using Windows XP since I have bought my old laptop HP Compaq nx6110 (1,4 Ghz Celeron M, 768 MB RAM). WinXP runs on this laptop really fast and smoothly, but I have turned every "eyecandy" off and it looks like old Win95 now. But I like this neutral look.

Last week I was closed in my room for two days installing and trying different Linux distributions. After this time I ended with Arch Linux installed on my hard drive - system was stable and either WiFi worked well. Then I realized, that I have spent so much time and done nothing useful. So I decided to work with WinXP and don't bother with other OS (like 2 weeks with Mac OS X a month ago).

But NO. Incidentally I got to this website and started immediately download the iso image. The download process ran in Java and I had download speed about 800 KB/s, that…
