whiterknight··on Show HN: Hosting my website using my C web server
I think this is vastly overrated:

- how much code actually gets read outside of top 2-3 projects?

- how many of those readers can detect security problems?

- why are others inherently better at detecting problems than the author?

Wouldn’t 1000 lines read by 2 people be better than a million read by 10?

whiterknight··on Committing to Rust in the Kernel
Sure, it just invalidates the impending doom, ban C programming narrative.

1000 lines are easier to secure than 5 million lines
whiterknight··on Committing to Rust in the Kernel
The point is that many of the problems rust aims to solve become much less relevant. For example, if your program only does 10 Malloc and frees, you can probably track down the memory bugs.

Side note: tell your startup to switch its “hardware with Ubuntu Linux inside” to BSD. You will have a much more stable and simple platform that can last a long time.

Are you thinking of a safari exploit that allows JavaScript to get out of the safari process? What’s the attack scenario?

I promise, you will be just fine without the security updates.
whiterknight··on It's probably time to rethink "Building in public"
Yeah and Apple didn’t make any money until after that phase.

> If you're trying to build a business then you must be always be selling and marketing.

Yes. I am only giving marketing advice. Sales is unfortunately embedded in so many other areas of life besides commerce.

> I doubt that there is still any real career opportunity in "applied" optimization.

I agree there are no ready made jobs for that.

But you yourself know there are optimization problems all over real life. It’s a sales problem. Companies don’t know what they need or who has it.

> there is nearly no career in "applied" optimization

Agreed. But that’s true of all PhDs. The only difference is business guys see “computer science” and have an idea of where it fits in their org. It’s easier to sell. But in reality there is no business for experts in complexity theory or category theory type systems.

Making money involves solving practical problems. Even professors take a two job approach, mixing official research to get tenure with stuff they are actually interested in.

> With a BS "With Honors" in math, I got strongly recruited

This is very unfortunate. Because professors grew up competing in an academic tournament for their jobs they think that’s how the whole world works.

whiterknight··on Does “building in public” work?
When it comes to marketing I think we can take a page from the Apple playbook. Never show anything incomplete. Critics and the general public don’t understand the artistic process and will only become uneasy. nobody cares how you did it. Just show results.

> I was naive. Knew much more about math and computing than people and personality.

Do you think not learning math would have helped you understand people at a younger age? It sounds like you just needed time to grow socially and in practicality. For most people on this forum, that’s a challenge regardless.

whiterknight··on Applied Mathematical Programming
Sounds like you opened up the newspaper and scanned for “mathematician”. Leveraging phd research into a great job is a tough. Re-skilling into a normie engineer/technician/analyst, is not.

My point is not to criticize your job hunting skills, it’s to suggest that this an undue psychological burden in your life and is perhaps masking other causes and personal challenges.

whiterknight··on Applied Mathematical Programming (1977)
You’re attributing these life challenges to your STEM PhD speciality?

I am sensitive to your hardship, but optimization has nothing to do with it. People are succeeding with bachelor’s degrees in Latin.

whiterknight··on Ask HN: Is a Masters in CS/Engineering worth it for a mid-career PM?
> you will forget almost all of the stuff your learned

Speak for yourself.

You are also developing a meta skill of being able to read technical material, and a fluency with basic concepts (algorithms, signals, etc)

Also sometimes learning something isn’t knowing exactly how to do it on the spot, but knowing it’s the right thing to look up when you need it.

Billions of views and total YouTube dominance disagree with you.
whiterknight··on OpenSCAD: The Programmer's Solid 3D CAD Modeller
> recording ui interactions, etc

This is a sign that the software has grown to become its own operating system. They also have to add their own version control… remote editing, etc.

Unix style versions of tools are interesting in their own right (photoshop vs imagemagick).

whiterknight··on FDA Authorizes First Over-the-Counter Hearing Aid Software
Is the hearing aid market big on modularity and compatibility?

isn’t it good to have multiple options so consumers can pick what they value?

whiterknight··on Going open-source as a VC-Backed company
Like people, VCs are also motivated by status, recognition, and making cool things.

If they were only financially interested they would play the game with much less status bias.

whiterknight··on Apple must pay 13B euros in back taxes, EU's top court rules
That’s ascribing a lot of power to the EU which I don’t think is politically cut and dry and certainly not a result of elections.

> ill-gotten gains

We are assigning moral value to this? You don’t think EU is a self interested party looking to interpret the law as favorably as they can?

whiterknight··on Playstation 5 Pro
It’s actually just because they all use unreal.

4k also requires upscaling or minimizing work per pixel, which encourages everyone to use similar methods.

whiterknight··on Core: an experimental new way to write videogames
The longer I am around the less true I find this. Can any good developer learn and contribute with a new language? Yes.

But there is also a peak performance achieved by using tools for decades that is not transferable. C experts didn’t switch to Java, they found different jobs.

For your core technology you want a few of those 5-10+ year guys.

whiterknight··on Convert textbook to online course with AI expert
If I’m going to take time out of my busy adult life to better myself, I’m probably going to prefer materials prepared by an expert who cares.

The scarce resource here is not high quality learning material, but time and effort.

Perhaps this idea has most value in new fields without established material.

Would you want to take a course that was generated?
whiterknight··on What's new in C++26 (part 1)
I absolutely agree. Move semantics exploded the language.
whiterknight··on What's new in C++26 (part 1)
The solution for move semantics before was specializing the swap function for container types. This was a much more pragmatic approach
