As yegge mentioned, there might be more appetite for trying out this idea now because there are many engineers who are currently unemployed. Offering them short co-op could be beneficial to both the engineer and prospective employer

As a next step, it could be cool to write unit tests against these screenshots that look for words like you mentioned. That way if a screenshot is updated and a test breaks you will know what documentation to update

One example where I think the law does make sense is for website URL paths.

Over time the paths may change, and this can break existing links. IMO websites should continue to accept old paths and redirect to the new equivalents. Eventually the redirects can be removed when their usage drops low enough.

It would be much snappier, and would trivially support common native features like being able to open messages in new windows.

Why would column-oriented databases be mentioned? My understanding is that these are typically used for OLAP, but the article seems to talk only about OLTP.

The performance of both the website and the iOS app is also not great. On the iOS app, I frequently see frames dropped and scrolling is sometimes blocked for up to a second or more at a time.

LinkedIn's feed is certainly not simple, but modern iPhones should be more than capable of rendering it at 60fps.

Well the executable binaries inside IPAs are encrypted, but the IPA bundles themselves are typically unencrypted. You should be able to see unencrypted assets inside of them

Fair point, I had not considered needing to read and understand code you didn't write yourself.

Especially in a corporate setting, not understanding a keyword you see in a PR could lead to bad code being checked in.

> 3. get rid of roughly 150 of the 200 keywords there are

I don't understand this point. Could you explain?

The new keywords enable new language features (ex: async/await, any, actor), and these features are opt-in. If you don't want to use them, you don't have to.

What are they keywords you think should be removed?

Not disagreeing with you, but here’s an article from Akamai about how using WASM can minimize cold startup time for serverless functions.

Yes. This page has several ways to get older macOS versions: https://support.apple.com/en-us/102662, but the earliest macOS version you can use on Apple Silicon is macOS 11.

If you move your home directory to a different disk partition, you can even share it between two different macOS versions!

My suggestion is no - first have them do it the hard way. This will help them build the skills to do manual memory management where defer is not available.

Once they do learn about defer they will come to appreciate it much more.

Prefer structs over classes != only use structs.

There are plenty of valid reasons to use classes in Swift. For example if you want to have shared state you will need to use a class so that each client has the same reference instead of a copy.

With the library you’re able to use stripe without thinking about web hooks. The library is named based on what it enables a user to do, not how it works internally.

Yeah customers are market validation, not merely the existence of competition.

If your competitors have customers, I think that is a sign of market validation. If they do not, then you might not either.

IMO the page is concise and well written. I wouldn’t call it very elaborate.

Maybe the page could have been shorter, but not my much.

I think the most common set up is to have your application server and DB on different hosts. That way you can scale each independently.
