They'd also do well to add some common sense filters. Amazon must have 5+ years of regular purchase history on my. You'd think thye could deduce by now that I am not in the market for pet and baby stuff.

Sometimes I'd settle for some vanilla common sense. Watch Episode 1 of something on Prime. You'd think next time it would suggest Episode 2, right? It does...its thumbnail #25 in the grid & below the fold.

Amazon can’t suggest a “product you might like” if their life depended on it. They have 19 years of purchase history for me spanning thousands of product categories. Want to know a category I’ve never looked at or bought from Amazon, women's handbags. What’s near the top of the suggestions right now on the homepage for me? You guessed it!

The weirdest thing is that at one point, I think it's now almost 10 years, they had somewhat OK recommendations. It's not like "you bought programming books and Battlestar Galactica DVDs, so you might be interested in Neal Stephenson's novels" is really advanced but it's still miles ahead of the "you just bought a washing machine, so you might be interested in washing machines" level.

I think the issue is that it’s no longer “recommendations”, instead it’s now “here’s the things which we can make the most money off you buying based on your recent spending”.

This is more of a product problem than a technological one. I don't think the issue is lack of imagination, but hostility from consumers. There are a million and one cases where a pdocut could be 10x better with 10% more effort from me,and where that tradeoff is more than worth it (hell, it's why I use Linux). But the average consumer is aggressively turned off by having to do any "work", and the type of person hangi…

I have already a solution where I can put zero amount of work for optimizing it, it's called a button. Why would I bother with something as needy as this "smart" thing?

I don't understand your comment or how it's remotely relevant to the thread. Is this just a non sequitur Luddite rant about the very existence of new tech?

The baggage weight limit has nothing to do with the weight of the aircraft. It is about keeping the bags light enough for handling, to protect the backs of baggage handlers (and automated equipment/belts). Unlike thier heavy bag, a heavy passenger is generally capable of walking themselves onto the plane.

If that's so, why is the luggage weight allowance applied cumulatively across multiple bags for one passenger? And why is it different between airlines and between ticket classes?

I'm sure some airlines do this. But most airlines allow 20kg per bag.

Some years ago, I worked on a team "Ads Human Eval" - we had raters hired to do A/B testing for ads. These evaluated questionaires carefuly crafted by our linguists, and then analyzed by the statisticians providing feedback to the (internal) group that wanted to know more about. So the best experience was this internal event that we had, where the raters would say that certain Ad would not fare well (long term), whil…

If you wonder why we still need humans, check this out - https://www.google.com/search?q=beverly+hills+properties - spotted the issue? maybe an AI could've caught it... or maybe lots of amazon-turk (or like) employed folks that give feedback on things...

Might be talking at cross purposes here: per bag 20kg is so the bag can be safely handled by staff.

When I fly between London and East Asia I shop around between different carriers and, in economy class, I'm normally offered up to two checked bags with a total weight of between 30 and 35kg depending on carrier and promotional offers.

Nah, you're not. I just gave up on mine and have a schedule. I also turned off "pre-cooling" because it would just kick on at like 6pm to "cool" the house for bedtime. I also bought several temperature sensors to use, which are fun. At night I have the thermostat use the sensor in my bedroom, then goes back to the main thermostat during the day.

See the next logical step is to outfit the output vents with servo-controlled actuators so you can fine-tune where the air is going!

Additionally:

- Use a python script to switch heating from my heat pump to my gas furnace when energy prices invert. - Have live monitoring of my HVAC pressure health so that my servo controlled actuators don't bork my system.

Building my own thermostat so I have total control was a fun project, I learned a lot about electrical engineering and built a circuit with some TRIACs to control the HVAC lines. Though I still need to give it an interface so I can program it some way other than uploading the program as a JSON blob to my raspberry pi!

This has been on my project list for a long time haha, would you happen to have any blog posts or references for those of us who aspire to do the same?

Sorry for the late reply! Hmm, I don't have any particular posts I followed on hand, but I learned a lot by watching ElectroBOOM and Ben Eater's videos on YouTube. A general background in C++ development made getting started with Arduino code (you can use arduino frameworks for chips like the ESP8266) a snap as well
