I have at Tesla system with 3 batteries, and I argued during installation to include 8kw of panels situated on the west side of our roof against Tesla ‘s engineering. The panels would only by 72% efficient on the west side as opposed to 74% on the east side (catching the morning sun). But my modeling showed that we would exhaust the batteries in the evening due to the fact that my usage was higher in the late afternoons and it wasn’t offset by any generation of solar panels during those late afternoon hours.
After modeling scenarios based on historical usage PER HOUR, I was able to show that if we had enough solar generation during peak late afternoon hours, we would be able to ‘survive the night’ on batteries until morning solar generation resumed. This means my 14kw solar panels coupled with 3 batteries gets me completely off grid for 9 months out of the year. That’s not bad considering I get 7ft of snow during winter months and I am surrounded by very tall trees.
Optimize on hourly generation not daily, most solar companies use DAILY numbers without a clue on hourly usage. I currently get 0.08$ for every 1$ in electric production, so there is very little benefit in producing electricity when you don’t use it. Optimize your system based on your usage not on DAILY production. If electric companies would give me credit of say 0.90$ per 1$ then the equation changes, but electric companies would rather benefit from your overproduction, be careful as these systems are not cheap!
This has been my experience as well. Rails can do a lot, but it also allows you to develop junk. Most sites built in Ruby end up in the latter category, especially if built by a team that doesn’t use basic software architecture patterns.
Why is azure ‘bad’? Is it because you dislike Microsoft?
In my experience Azure is really good and getting better. Even if AWS is more popular, Azure is gaining traction, is more intuitive and easier to use, and in my experience: cheaper
If you even have a remote chance of running in this race I recommend you go. I raced in 2006 and 2007 and it was by far the most fun you can have on four wheels, and the people are just amazing and welcoming. When you are racing a car you care very little about you experience real racing and it equates to real fun. One of the best things I have ever done.
Do people forget that a 40 hour work week exists because of unions? Did we forget that having weekends off and holidays off was not a thing until unions? Did we also forget that children were put to work at a young age until unions?
Have you seen the salary requirements for these jobs? People are being paid way more than they were being paid 10 years ago. Nobody, and I mean nobody, is turning down jobs because of insufficient wages. The perceived ‘value’ that an employer sees is the ability of being able to exploit a younger engineer with ridiculous timelines and all night ‘coding sessions’ because they don’t have a family waiting for them when they get home.
The mere statement that a 5 year ‘Senior’ software engineer has more perceived value than a ‘Senior’ software engineer with 20 years of experience is just crazy. Let’s replace ‘software engineer’ with ‘electrician’ and then tell me this is sane.
I am old enough to remember when cubicles and offices were the norm. Cubicle companies studied and improved the cubicles spaces to make them more efficient using science. Yes they actually studied what would make us happier and more proficient at work.
Then came the stupid trend of organic seating. Cubicle’s ? Thing of the past they said, yet our productivity suffered. Great for sprints but quickly diminished due to constant distractions forcing engineers to invest in noise canceling headphones.
The WFH movement is because water flows downhill. We learned that we made the office an incredibly inefficient place to work, because we didn’t follow the science and threw away decades of research because of a new ‘fad’ that the CEO’s liked. Too bad CEO’s, I have been WFH ever since corporate America thought organic seating was cool.
I will never go back, in fact us programmers should unite and unionize to solidify this benefit before they try and take this away for good and make our jobs more difficult.
