It's similar but doesn't need a click to start the drag and another to end it. You just grab things with three fingers and move them; lift when done.
It also lets you select multiple whole words with the mouse: single tap quickly followed by holding three fingers and dragging.
I have read lots of non-fiction books about programmers and engineers that have been very inspiring, they're just not technical: "Masters of Doom", "Blood, Sweat, and Pixels", "Coders at Work", "The Idea Factory", "The Soul of a New Machine", "Dealers of Lightning"...
"Programming Pearls" might be an exception—there are some great real-life stories and problems to think through in that.
Maybe also "The Art of Computer Programming" but I can't speak from experience (I'm not ready to tackle that one yet).

The way it's been explained to me, Rails packages (gems) are like prefab bathrooms and kitchens. Compared to e.g., Node.js packages which provide things like "sink" and "tap" and "door handle."
E.g., in Rails there's a popular auth package that includes password reset and recovery functionality:
https://github.com/heartcombo/devise
Always a pain to build, and not something these popular Node.js packages save you from doing over and over again:
EDIT: It sounds like I'm picking on those packages. I don't mean to, just want to highlight the difference in philosophy between the Node.js and Rails approaches.
The tricky and interesting bit is figuring out actual emissions (vs applying a rule that 1 visit == x grams of CO2). Work in progress:
There seem to be markets (or large enough organizations?) where coding job ads get a tonne of applicants, many of them inexperienced, and so automation is a good fit. But not when things are tipped the other way.
Our bet was for real-world tests too but it wasn't enough. A few things we missed that might help…
- Candidates don't want to be treated like cattle
- For many companies a good interview platform will be more beneficial than automation
- Companies say they care about the experience candidates receive, they'll say they're rigorous and try to be as objective as possible with the way they collate information and make decisions, they'll talk about how high their standards are, etc etc. Be weary
- There may be more gains to be made outside of the tech space
- The problem most companies complained about and is probably still the hardest: going out and finding people
I like the way you've solved the "real-world challenge" problem.
Good luck and all the best!
My friend Ricardo and I feel very strongly about climate change, so we've built a service that makes websites carbon neutral. To get an idea of the impact of the internet on climate change, if the internet were a country, it would be the 7th most polluting country [1]. If unchecked, one prediction puts the internet at 14% of global greenhouse gas emissions by 2040 [2]. Our service looks like this:
- You add a script tag to your site
- The script calculates the electricity used
- The greenhouse gas emissions are removed through carbon removal technology
Also work in progress is a way to provide insights to help reduce your website's emissions.
Obviously the web is only one part of the internet emissions equation (the other parts being streaming, large file transfers, computationally-intensive applications, etc), but it's a massively visible part which is what we think can make this worthwhile.
We believe people who work online—developers, content creators, publishers, etc—have a huge influence, and a message like "This website is carbon neutral" could have a knock-on effect and really help push things in the right direction.
In terms of carbon removal providers, we're using services vetted by Stripe and Microsoft. We rely on them because the space is complex and they have very high standards.
Another benefit is that they back novel solutions that have a while go until the costs are affordable enough for global adoption. This is important because the more support these solutions have, the more likely their costs will come down and become easier to scale.
We'd love to hear your thoughts. If you have any questions, we're both around.

> My conclusion: Management is the most noble of professions if it’s practiced well. No other occupation offers as many ways to help others learn and grow, take responsibility and be recognized for achievement, and contribute to the success of a team.
I'd be very interested in actual data that compares virtuous and unvirtuous cultures, out of curiosity of course!

—and "modern" equal temperament:
https://www.youtube.com/watch?v=HEbi-7tPaqo
As much as people describe just intonation as pure, etc, at least in this example it just sounds wrong to me.
As far as I understand, just intonation requires instruments to be tuned differently for different keys and stops "working" if a piece strays from the key (which music from Bach's time will often do).
Equal temperament is our workaround for the physics which doesn't quite match the 12-tone system.
It seems that that's insignificant compared to the type of food we eat:

> Shipping one kilogram of avocados from Mexico to the United Kingdom would generate 0.21kg CO2eq in transport emissions. This is only around 8% of avocados’ total footprint. Even when shipped at great distances, its emissions are much less than locally-produced animal products.

It's not for everyone and that's fine. I have some suggestions to try though.
