Draw a crystal ball with two-color particles

This is real work, not a feature someone invented — it comes from real job ads and real questions people asked. Below are four ready AI prompts: get it done, make it easy for the next person to say yes to, work out the right move when you are stuck, and stop it coming back.

Plot a sphere with a radius of 5, centered at the origin. Fill the left hemisphere with blue particles and the right hemisphere with red particles, making sure the particles are visible and distinct.

Before I present this crystal ball simulation to Professor Davies, make the particle distribution look more natural and less uniform. Can we add a slight random jitter to their positions, and ensure the color transition at the equator is smooth, not a sharp line? He always critiques artificiality.

CDecide — diagnose the stuck momentI've generated the crystal ball simulation with the two-color particles, and it looks perfect…+
The crystal ball simulation looks right on my screen, but when I send the image to Dr. Albright, the colors are off.
I've generated the crystal ball simulation with the two-color particles, and it looks perfect on my monitor. But when Dr. Albright views the exported image, the blue looks purple and the red looks orange. I'm afraid she'll think I'm colorblind or sloppy. Is it a color profile issue, or something about the image format I'm using? What's the fastest way to get her an accurate representation by the end of the day?

DBecome — change the patternI'm constantly losing hours adjusting plot aesthetics and color maps for different audiences…+
I keep spending too much time tweaking visualization parameters for presentations.
I'm constantly losing hours adjusting plot aesthetics and color maps for different audiences and display types. It feels like every time I create a new visualization, I start from scratch, even for similar data. How can I build a more efficient habit for creating publication-quality figures that consistently meet reviewer standards without all the last-minute scrambling?

Questions people actually ask

honest answers, no sign-up

Every task here was seen in the real world. Someone doing the job named it, a real job ad asked for it, or a lot of people asked about it online.

If nothing real showed a task, it is not on the page. That is the whole rule.

They are the same job approached four ways, because what you need depends on where you are.

Get it done today. Make it easy for the next person to say yes to. Work out the right move when you are stuck. Learn the pattern so the job stops coming back.

For most of these jobs it can carry the heavy thinking - draft it, sort it, check it, rehearse it with you.

It cannot sit in your chair, take the blame when a number is wrong, or notice what nobody wrote down. Let it do the first 80%. Keep the last 20% that is truly yours.

No. Copy any prompt and paste it into the AI you already use. No account, no score, no wall in the way.

Any of them. The prompts describe the work rather than naming a product, so they are not tied to one assistant.

That is also why they keep working when you switch.

Change it freely. Every prompt is a starting line, not a rule.

Put in your real numbers, your real names and your real deadline. The more you make it yours, the better the answer comes back.

The tasks come from real job ads, published job data and the questions people ask in public forums.

The steps come from MATLAB's own documentation, with practitioner sources for the traps the manual does not mention.

Push once. Ask it to sharpen the weakest part and to say what it assumed.

Most wrong answers come from a missing detail rather than a bad prompt - tell it the thing it could not know.
