I got a new car. And this August/September we brought it on a nice roadtip from Dublin to Scotland.

Hardware-ish project: Display for Netatmo Weather Station

Vladimir Rusinov — Sun, 21 May 2023 19:30:46 GMT

I've finally published a small project: ESPHome-powered display for the Netatmo weather station.

This is ESPHome-based display for Netatmo weather station. The primary goal is to display indoors CO2 concerntation in my home office so that I know when to open a window. Or when to close and hopefully save some money on heating.

The device itself is not a CO2 monitor and requires Netatmo to be working with HomeAssistant.

Leaving Google, Joining Snowflake

Vladimir Rusinov — Sun, 12 Feb 2023 22:04:14 GMT

This Friday was my last day in Google. Tomorrow will be my first day in Snowflake. I loved my job in Google but after over 10 years it was a time for a change. It is a big change.

How learning is different from fixing

Vladimir Rusinov — Sat, 07 Jan 2023 23:00:49 GMT

I've started a page where I intend to collect links to various materials that I liked.

Today's addition is John Allspaw's talk Incident Analysis: How Learning is Different Than Fixing. The talk is only about 20 minutes long (the rest are questions and I didn't find that part particularly interesting). In the talk John describes common pitfalls of incident analysis.

A few points that resonated with me:

Severity of the incident has nothing to do with how difficult and interesting it was
Good postmortems are stories - they use typical story-telling techniques and are interesting to read
Often postmortems become box-ticking exercises. Many postmortems are written to be filed, not read. This happens even in pioneering SRE orgs like Google.

Spend 20 minutes of your time, it may be worth it.

House renovation: August 2022

Vladimir Rusinov — Tue, 30 Aug 2022 12:33:22 GMT

A month spent refining detailed electrical, ventilation, plumbing and structural designs. Nothing exciting.

House renovation: July 2022

Vladimir Rusinov — Sat, 30 Jul 2022 20:45:26 GMT

Another moderately busy month. Philip was working on detailed design and advised us to continue looking at finishes, etc.

House renovation: June 2022

Vladimir Rusinov — Thu, 30 Jun 2022 17:37:50 GMT

Busy month with no visible progress.

As expected, planning application received no appeals. So we are good to go.

Thus, we are ready for... not construction yet. But for more design work. With more details now. Electrical, mechanical, etc.

Windfarm walk

Vladimir Rusinov — Wed, 29 Jun 2022 08:14:03 GMT

There is an interesting walk on the border between Wicklow and Wexford in Ireland. The walk is unusual as it in the windfarm. I didn't have an opportunity to walk under the wind turbine before. It's an interesting experience and it was worth a drive from Dublin.

House renovation: May 2022

Vladimir Rusinov — Mon, 30 May 2022 17:13:38 GMT

The planning permission is approved.

However even though it's a "clean" approval with no unusual conditions and no protests/submissions, we now need to wait until beginning of June in case there is an appeal.

House renovation: Apr 2022

Vladimir Rusinov — Sat, 30 Apr 2022 18:07:39 GMT

No objections submitted to the coulcil about our planning application. But no decision made yet.

So we wait.
