# whoami

My name is Patryk, I'm 34 years old and I live in s/Krakow/Cracow/ Poland. I'm a father and husband. I work as Site Reliability Engineer in Security and my primary focus is always on Performance, Security and High Availability.

My father brought the first computer ATARI 65XE into the home when I was 3... and this is the first thing I remember from my childhood. ;-) the next computers were Amiga 600 when I was 8 and finally the first real PC (Intel Pentium MMX 233 MHz) when I was 15. Currently I'm using Mac on primary workstation and Linux on all of my servers. Definitely computers changed me and my life... I've spent 90% of my time on this planet around the keyboards and monitors... and I still love it. ;-)

# witness host

Witness node is located in France and hosted by OVH,

  • 4 cores, 8 threads (dedicated server, passmark benchmark > 9k)
  • 32GB RAM
  • SSDs in RAID
  • for security and monitoring: munin, rkhunter, fail2ban, iptables (with DROP as default policy), zabbix
  • feed price update is automated by steemfeed [thx @clayop for this tool]
  • server and services are monitored from external host (I'm going to setup backup node as soon I will start signing the first blocks) ;-)

# my goals and challenges as witness

As witness my primary goals will be to support Steemit community, understand all details of the network to make best decisions when it comes to HARDFORKs and share my technical knowledge and experience I gathered by the last 15+ years in IT by working as Network Specialist, System Administrator, Infrastructure Architect and SRE. I see this as great opportunity and challenge for me.

Thank you for your trust ;-)

tak trzymaj :-) im więcej naszych tym lepiej :-)

Nie za bardzo wiem co to za "świadkowanie", ale powodzenia :)

"Świadkowie" to osoby które utrzymują witness node-y, czyli serwery generujące (zatwierdzające) nowe bloki w łańcuchu Steemit oraz publikują cenę STEEM/USD
w sieci. Do zadań "świadków" należy wspieranie sieci Steemit, co można robić na wiele sposobów, pomoc techniczną, budowanie użytecznych narzędzi dla społeczności lub propagowanie informacji o sieci tak by jak najwięcej osób dowiedziało się o nas. Każdy użytkownik sieci Steemit dysponuje 30 głosami (https://steemit.com/~witnesses), które może oddać na zaufanych "świadków", jest to bardzo ważne do prawidłowego działania zdecentralizowanej sieci, ponieważ eliminuje możliwość "centralnego" zarządzania krytycznymi zmianami w sieci i np. HARDFORK może się odbyć jedynie jeśli większość witnessów przepnie się na nowszą wersję softu ;-)

Mam nadzieję, że trochę udało mi się wyjaśnić rolę świadków ;-)

Dzięki, mam jasność. Uczyć się trzeba cały czas :)

you have my vote! good luck!! i would like to be a witness too! i want to contribute to the network and share my knowledge also!

I know this post is a little old...

But just a heads up, OVH is a terrible place to host a witness, many witnesses have learned this the hard way.

Steemd is reliant on stable network connectivity 24/7, with not so much as a minor blip. OVH cannot provide that (there are plenty of budget hosts that can, but not OVH).

At @privex we offer servers which are safe to use for witnessing, and even back our claims with an SLA. Of course there are many others to choose from, and I'm sure as someone experienced in High Availability you probably already have servers with many other providers.

You might not notice these issues until you get into the top 50, but OVH are most definitely problematic for STEEM systems as @klye and @themarkymark can confirm.

Witam. Jestem tutaj nowy ale chciałbym ci tylko powiedzieć, że w mojej rodzinnej miejscowości Żabin jest dość duża rodzina z Twoim nazwiskiem.
Pozdrawiam z Kalisza i życzę wszystkiego dobrego.
