Conflicted every time I start a personal project with Amazon web services. Lambdas, S3, Route 53, and Dynamo DB all allow me to bolt a prototype together pretty quick. Serverless architecture means I don’t get caught up in infrastructure like I did for a year with my own k8s cluster... Finishing some projects in an afternoon is a great feeling but there is a dark side.

Amazon treats it’s warehouse workers like cattle and their anti-competitive nature is sketchy. Bezos commissioning largest private yacht to ever sail while workers struggle though covid... sick

Yet here I am, thinking of my next aquarium sensor project and how AWS timestream would be perfect for the data.

Loving Zappa lately. I use it for creating quick scraping AWS lambda fns that dump data into S3 as RSS feed XMLs. Then just use my feed reader mobile app to stay up to date.

I doctored the image to remove skin, further justifying Affinity Photo purchase. No subscription BS like with Adobe and skills transfer.

Lunch above Lake Garda.

A bigger boat makes for a more comfortable sail. Yesterday we took a 8.5m cruising yacht out for a day on Lake Garda.

Full blog post after the trip.

Nitrate and Phosphate dosing stuff came in! Raised nitrate and it has stayed at 2ppm for a few days. Brought phosphate up but it seems zero within 24h. Put it on dosing pump dosing .06 ppm with everyday. Let’s see

@tendigits added your RSS to my feed app. Looking forward to more recipes.

Current reef tank challenge: Lack of Nitrates and Phosphates in the water has created a vacuum for dinos and cyanos to grow. As exhibited by the pink film over the sand bed.

Plan of attack: lowering photo period on cheato didn’t have much effect and heavy feeding also didn’t do much. Going to try dosing directly.

@Wraptile went scuba diving for the first time a few weeks ago in Croatia, PADI open water diver course. Would love to do it in Thailand. 🤿

New additions entering quarantine.

Black clown fish. Hopefully my purple/gray hammer coral will host them.

Adding some creepy crawlies today.

The tank survived a week without me. Automated feeding, dosing, ato, and lights all worked. Had one polyp of frog spawn die, lack of flow perhaps. Other then that good growth. My foxface even got a little fat on rich pellet diet.

Hopefully this opens the door for more vacations as Corona situation improves in Europe.

Tried and true passwords manager. Been using it for few years now. 👍. Main caveat, I don’t do online shopping on my phone so being more restricted to desktop is fine for me.

@hecanjog What watch you rocking?

So far maintaining a stable alkalinity in the reef has been a real challenge. I only have three small corals, 5 fish, and rock but somehow I lose 1 dKH per day.

I’ve started with manual daily doses Red Sea part B to keep it up to the recommended 11/10 dKH. Quite a ways from the 5ish dKH of my RODI water. Daily testing and dosing was a pain. I learned 10 dKH for my system is just not practical. Maybe some day for accelerated SPS growth but for now 8 dKH of ocean water would do.

Next I tried Kalkwasser, complete with a diy dripper. Unfortunately it make quite a mess and didn’t maintain and alkalinity of 7 dKH. 🤷‍♂️. My theory, not enough co2 inhibiting carbonic acid + calcium hydroxide alkalinity raise.

Now I’ve gone back to the RedSea Part B but this time slowly dosing it via a Aqua medic Evo 4 dosing pump. After a week of tinkering I’ve got it maintaining a pretty close to 8 dKH with a loss of .1 dKH per day. 👌

In the coming weeks I’ll try to stabilize that even further and automate my calcium dosing as well. All in prep for more sensitive corals.

Congratulations to ink team on ink version 1.0 release. I’ve used it in the past to write interactive art projects. Narrative scripting is super run.
