Salaries for different levels of job for a bunch of companies

I really like the original one, and this is a solid reply

Lot of good parts

The high performance parts aren’t React. Mapbox GL, for example, is vanilla JavaScript and probably should be forever. The level of abstraction that React works on is too high, and the cost of using React - in payload, parse time, and so on - is too much for any company to include it as part of an SDK. Same with the Observable runtime, the juicy center of that product: it’s very performance-intensive and would barely benefit from a port.

The less interactive parts don’t benefit much from React. Listing pages, static pages, blogs - these things are increasingly built in React, but the benefits they accrue are extremely narrow. A lot of the optimizations we’re deploying to speed up these things, things like bundle splitting, server-side rendering, and prerendering, are triangulating what we had before the rise of React.

Amazing collection of large numbers and small languages

This is joy

That squares with my experience of software development. It’s like being a furniture maker but spending 80% of your time fixing your goddamn hammer because it keeps breaking and no better hammers exist, or consulting glue-drying tables because they keep changing your glue on you every hour or two and for no good reason every single glue performs differently while accomplishing the same thing.

Ive noticed some people use github almost like a social network. A rough analogy to Twitter would be that starring a repo is similar to liking a tweet, and forking it is almost like a retweet.

Love this term - this is exactly how I learn. Start by skipping over the details,
develop a coarse understanding, then refine your knowledge by learning about specific areas in more detail.

It is a long lesson that I am still not through, will see if it can live up to the bold claim of its title

Many helpful perspectives

Great way to learn things, and to make exactly the thing you want.

HN discussion

The Show HN for this has some alternate great tools for similar things

Interesting estimates and numbers - clientside savings really add up.

In fact, it is probably the most effective use of my time when it comes to reducing carbon dioxide emissions.
Just last week I reduced global emissions by an estimated 59.000 kg CO2 per month by removing a 20 kB JavaScript
dependency in Mailchimp for WordPress. There’s no way I can have that kind of effect in other areas of my life.

Highlights:

• People exhibit overconfidence in their ability to calculate exponential growth
• People exhibit overconfidence in their ability to use a spreadsheet
• The results suggest insufficient demand for help and tools

Continuing on why touchscreens are a shitty interface, especially for vehicles

Interactive examples to learn through reading and play. I looked at a music one and it was one of the best visualisations of notes/harmony I’ve seen

Went through a few of these in December and was pretty great. Unsubscribing from services/lists, and deleting a bunch of notification mails.

I noticed this as well. Went from wanting to code all the time, to wanting to do something not web related in spare time. Hobbies are important!

Constrain the infinite vastness of space to the bridge of a single ship

The problem with economic model of scarcity. More savings does not mean more spending - people eventually have enough cash and enough things; at this point they are taking more money out of the economy than putting back in.

I love this, and have experienced it first hand too many times. But a single text file has worked well for me, and saved.

Few other interesting ones in comments. I am terrified of the McCollough effect

However, Jones and Holding (1975) found that 15 minutes of induction, when time-elapse testing is employed, can lead to an effect lasting up to 2.8 months

A look at the music industry. You can’t make money from album sales, or from touring. Either have to do it as a hobby or get into the merchandice game.

A walk through how fast different types of train can go, and why. Great balance of history and physics, detailed but without too much assumed knowledge.

All three volumes of Game AI Pro available online! For free!

A wonderful, horrifying read. This makes me feel better about all the terrible things I’ve ever done on computers

Tablet multi-tasking is awful, and inconsistent. The form factor has potential, but it hasn’t made much use of it yet

More negative knock-on effects from decades of demonizing fat

Some great suggestions - assessing quality of free stuff is always tricky (esp audio), so a high-level filter is a good start

Reasons not to study the history of philosophy. Greek/Roman writings are not sacred texts!

We continue to encourage an outmoded mode of home ownership, and incentivize buying in spite of no economic argument

Course is WIP, chapters are all very short but shows promise. Some good other links to courses and material in HN thread
