A magnet in a coil operates both ways, this is non intuitive but perfectly sound. Not sure if it's mentioned in the article but microphones can be speakers too...

> It’s also THE language you use when writing UIs I'm unsure that I agree with this, for my smaller tools with a UI I have been using rust for business logic code and then platform native languages, mostly swift/C#. I feel like

I'm not entirely sure that this is true. I haven't actually looked into this but it might not be the realm of possibility. But you are generating a frame on GPU, if you can also encode it there, either with nvenc or vulkan doesn&#

Good strong (read specific) types encourage easier redactors. Changing the function signature or the type then generated cascade of compiler errors that tells you exactly what you touched. Weak non specific types does not have that property

I don't think fear or legal action makes it illegal. If I know it is legal to make a turn at a red light. And I know a court will uphold that I was in the right but a police officer will fine me regardless and I would need to go to act

Of all the self help books I have actually read, The 7 Habits is probably the one that had consistently been useful in actually navigating issues day to day. And I read it probably closer to two decades ago.

Let me ensure I understand you. Running a node.js server on Tahoe makes your macbook sluggish and you feel like Tahoe is fine performance wise? May I reminded you that 10 years ago people also ran chrome and node js webservers and this was

Just not having a Celeron level chip is worth the difference... Windows update on a Celeron chip makes it 100% utilisation with full boost. I would actually rather but an Android phone than a laptop with a Celeron chip for the same price.

From my knowledge RCU/epoch/Hazard pointers are useful in data structures and algorithms where raw atomics cannot be used but you still nees lock free or in some cases wait free semantics. If you can use an atomic then these are o

It is extremely complicated to do so yourself. Handling energy efficiency/a11y/i8n is non trivial in any language, using the paved road of the system's native implementation solves for many of those problems out of the box. Y

Where is the extensive tooling support for this use case if that is where you think it fits? Apple is all in on Swift, so you will not be writing native MacOS or iOS code for UI in D, best case you put your business logic in D but you can d

There is a pretty significant difference between the way JS is used there and in electron apps. This might be what you were getting to but I tend to agree with the idea of place all the interaction logic in a high kevel language and get the

Every time I see this take I ask myself if the person commenting does not understand that by definition a runtime has to do more work than a strictly compiled version of any said code and therefore can never be quicker. To steelman your arg

In my experience agentic coding is still bad a context management. I can get amazing results from a chatbot based workflow where I manually provide any context needed, if the agent can happily pull files into context on it's own it ten

I want to reiterate the points other have brought up. Learn more about whatever domain you are writing software for, then ask what skills you need to improve to solve a problem in that domain. Also do not get hung up on specific languages o

That clarifies a lot. So effectively it was at least partly guided refactoring. Not blind vibe coding.

Reading the code and actually understanding the code is not that the same thing. "This looks good", vs "Oh that is what this complex algorithm was" is a big difference. Effectively, to review that the code is not just be

Rust prevents the footgun, but also prevents shooting in the direction where your foot would be even if it isn't there. There are absolutely places where that is required and in Rust those situations become voodoo to write. C++ be defa

This is more akin to selling a car to an adult that cannot drive and they proceed to ram it through their garage door. It's perfectly within the capabilities of the car to do so. The burden of proof is much lower though since the worst
