In 1998 I wrote a financial summary for our ERP system (EUROnet) running on MS DOS with a dBase db in the backend. I've connected the dBase to a PHP 3 web server with Apache 1 and then summarized the sales data. My boss loved it. He could see numbers which are not implemented in the ERP reports.

same here. still running on the previous version on all devices. Gonna sit this out ...

Yes that is the SBB in Switzerland but they do not turn the lights, instead they turn on the heaters for the track switches. Not sure if that is all rumours.

For solar excess charging I use evcc.io

When I charge the car via battery then only down to ~75% for now. The remaining energy is needed by the house during winter months.

Of course it is a bit oversized.

We’re living in a big river valley where we have fog from October until March. On some days in November the fog is so dense that the whole system does not produce any kind of energy. On the other days the produced kWh are enough to charge the battery.

We have a heat pump (extrem efficient), servers, one electric car, etc which consumes all together around 13MWh per year. The solar system produces around 27.5MWh. Most of the energy gets fed back into the grid.

We’re currently investigating to connect the neighbour houses physically to us. But that takes even more time here :-(

I did build my own solar system too. In Switzerland.

Took me 1-2 month planning and then 3 month building it alone nearly each day. Sept 2023 til Xmas 2023. Got all the hardware from a PV dealer friend on his purchase price level. Even 24 panels I have put myself alone onto the roof. With two persons it was a bit better.

I've got: 420w x 71 Trina solar panels and two SolarEdge inverters. SE10K Hybrid and a SE17k. Also a 24kWh BYD LFP battery.

All prices without state funding: Offers from local installers for 56*410W Panels without battery were around 65k CHF.

I've paid now 44k CHF including every kind of cost associated with building it.

Should write a blog post about it :-)

Next project is a solar fence with 6kWp.

Location: Greater Zurich Area, Switzerland

Remote: Yes, occasional travel within CH,DE to the office possible

Willing to relocate: nope

Technologies: 25 years in e-commerce, Golang, PHP, JavaScript & TypeScript, Kubernetes, MySQL, MongoDB, Magento, SolarEdge(ModBus). Does not need to be a dev job, can also be consulting/team lead.

Résumé/CV: on request / confidential

Email: kontaktcjs at gmail dot com

I've did this all and currently installing a ~29kWp solar roof myself here in Switzerland. I will pay less than one third of the costs as when it gets installed via a company.

well written post!

one minor thing: I've skipped using build tags for integration tests because those tests will be out of sync one day with your main code, even with Goland (?).

Instead I use the usual test and check if an environment variable is set, if not, then

    t.Skipf("env var %q not set, skipping integration test",envVarName)

or you can use an additional CLI flag, e.g. in `feature_test.go` write

    func init() { flagIntegration := flag.Bool("test.integration",false,"run int tests") }

then

    $ go test -v -test.integration

using it for years. much better than gofmt. thanks for all the work!

I also have a pihole in my network and it blocks 30% of all requests. But for TV I use a NEC MultiSync ME501 50“. A dump display. Use it my home gym for Zwift and workout displays.
