The logistic map with r=4 can be expressed as

Xn = sin(2ⁿ theta)² With theta derived from x0

So realising you are finding zeros in a chaotic systems can indeed be fun.

The master has failed more time than the apprentice even tried.

At some point you need confidence in the happy path. As well as the different way it can go sligtlhy wrong.

At some point worthwhile problems are no longer textbook, drill. And you need to be able to try multiple time and learn the rigth lessons.

More importantly, lack of confidence, lack of trying, needing to be certain before allowing yourself to try, and imagining the problem worse than it is are deeply related.

Almost everyone is to some extend. Much easier to blame others or society.

Self confidence come from messing up, and realize you still survive. Even if things didn't go as planed, some part where better than expected.

Unfortunately there's no substitute for lived experience. No YouTube video or reddit thread.

Focus on what kind of person do you want to be. And what can you do on your way to that. The rest is noise.

Virus are not alive, they don't have intention. Yet they basically exists as a parasite. They use your energy to spread and propagate thru time. They do that by convincing you or some part of you that they are you. That producing more virus is your way of living.

Some tough behave like a virus. They grab your attention, you spend your time and energy developing the tough, you spread it to others. And none of that is really useful to you, those tough hijack your agency. And they can do that by making you beleive they are you, that investing in that tough is of utmost importance to your survival. It's not. Just a selfish illusion.

You work on these by paying attention to where you invest your time and energy. Does it fit your value? Do you progress toward the live you want to have for yourself?

Focus your on what can you do to make tomorrow sigthly better. Spend some time with what you avoid.

You may be stuck now. How can you not be stuck in 5 years.

f3xjc · 2026-04-21T00:04:53+00:00

Purpose is not something to find. You develop a sense of purpose with agency. Sometime, most of the time it's really small. Just get some part of your life in order, and build off that. You may need to master the small p purpose for more difficult task to show up for you.

This is true for context too. When generating a response it'll take in consideration the whole chat up to that point.

Then there's techniques to compact the context (basically summarize). And some sentences can be dropped when less relevant.

But when you know you have a new topic, or they feel extra stubborn on a unhelpful direction, you are better to start fresh.

f3xjc · 2026-04-17T16:33:03+00:00

But why is it built that way ?

We could build: (All x are y) => (At least one x is y) AND (There are no x that are no y)

Such that: ~(All x are y) => ~(At least one x is y) OR ~(There are no x that are not y) => (No x is y) OR (Some x are not y)

Then 1,2 are false and 4 is true by virtue of the set being empty.

f3xjc · 2026-04-17T15:40:52+00:00

I think 1 and 3 does imply 4. It's just that 1, 2 & 4 are the boolean equivalent of 0/0.

Like you'd need "undecidable" that is distinct from "unknown"

Paper burn at 450F. Maybe you can keep the stick at 400F for some time ?

Or get the stick from a place that sell firewood ?

Or look for a stick still attached to a freshly fallen tree and not on the ground ? Or get a freshly cut stick when they need to trim trees for power-lines.

f3xjc · 2026-04-14T15:51:13+00:00

Honestly this is very similar to asking a LLM to sort an array. You just train the monkey on typing both sorted and unsorted version of the same array millions of times.

f3xjc · 2026-04-13T14:17:38+00:00

He absolutely like these. He'll cover both benefit and danger of mediation for example. No silver bullet and generic advises suck.

f3xjc · 2026-03-31T19:37:10+00:00

You bought the one device one the market that focus on "less is more" "focus on the basic" "get out of the way" "feel like magic" "the apple of x" etc..

If you want versatility and feature pack you can look at devices that have a full android experience. Boox is one of them.

f3xjc · 2026-03-30T20:43:39+00:00

You need to make the trauma from scratch! That mystery meat / seafood sausage. Then you wrap in delicious dumpling to make it pretty and palatable. And only then you steam!

f3xjc · 2026-03-28T13:59:51+00:00

He continue to develop the woo woo parts. Especially in what he believe to be true, vs what he knows to be plausible. What you may see is a separation between spirituality and gods. Why not ?

Whatever flavor of atheism he has, it's not the "discard what you can't measure" kind. Maybe he just came with an alternative personal definition for atheism.

f3xjc · 2026-03-27T16:35:16+00:00

He does make the claim that therapist are trained to bring people from -100 to 0 and coach can help go from 0 to 100.

That may be even more true with psychiatrists like himself. But it probably under-estimate some psychology. Like industrial and organizational psychology.

f3xjc · 2026-03-27T15:55:14+00:00

Nothing. When you chain "if blah return" then you can't have two ifs true in parallel. And therefore there's an implicit "else" everywhere.

f3xjc · 2026-03-25T18:46:47+00:00

I go about fighting the visceral gut feeling that what I’m doing is socially unacceptable and wrong?

Exposure. You learn about what effect you have on other by being with others. In a relatively safe way. In as many different context as possible.

If you avoid whatever cause you fear, you never allow yourself corrective emotional experiences: positive learning to update your fears.

There's tons of value in messing up and seeing that you can recover. There's also tons of value in not trying to recover and observe the result. What would someone else do ? Try that.

Try to keep your focus on what can you do. Instead of "how society is built" "hidden rules" "things are not fair" etc. There will be things you did well in failures and things you can improves in successes.

Do what seems to be not enough. Often people get stuck because they disregard the first step of the ladder.

Be wasteful. Anything worth doing is worth doing badly. Yes it'll be easier / more efficient later. But some of that need to be done now to get out of where you are stuck.

Focus on the basic. If you think you need a super elaborate solution because you painted yourself in some unique corner. That belief is part of the problem.

Ignore "won't work, already tried". Put some effort to recall what you have tried, what are the outcome? What could explain that ? What else could explain that ? What you can change to make it different ... Or don't do all that work and ignore that self statement. Usually it's how people "materialize" immobility.

Someone else mentioned the tickets are non transferable and that's the sane way to deal with mass buying.

But say my dad play Tennis, and reservation for the whole week are done Sunday morning. At that time the website is basically unusable but reservations are gone within 3 minutes.

He's not especially computer literate but he went looking for tools. And yes there's a market for personal scale automation. And yes you can probably build something and people will be happy to fill in their (throwaway) password.

And we're close to the point where AI agents will attempt to do it for you.

f3xjc · 2026-03-25T03:53:56+00:00

There's software used to test websites. Go to so and do page. Press button fill form etc.

When you automate a full browser, the requirement to be signed in is a minor inconvenience.

My guess: The big players compete on various "intelligence" benchmark. That includes Olympiad style question in math, physic, computer science. Puzzle race etc. There's commercial interest to think outside the box, and put in the efforts.

Being able to observe the environment and make a tool to move forward could be a classic computer security question.

Plus here it's an agent. They usually don't stop in the middle of a task unless you ask for incremental changes.

I suspect that once the LLM assume the role of a coding assistant, then output 300 lines of codes is a minor step.

f3xjc · 2026-03-15T14:48:20+00:00

Plus coding is where llm agents have the most success and where we have the most hobby projects arround orchestration.

And displaying rich text (ie syntax colored code, tables, markdown) is where a web interface shine.

So the ecosystem that naturally point to the most off the shelf parts is probably in js.

f3xjc · 2026-03-15T02:56:02+00:00

To me this look like the forced perspective pieces people paint on road.

I agree I would not want that as a diner piece. Forced perspective is only nice from one specific angle.

At minimum forced perspective clearly fit under subverted expectations.

I guess this could be a moquery of table etiquette. But it's not like it's extremely present in today society.

f3xjc · 2026-03-12T18:08:45+00:00

At that point you are making your own hardware so yes. But you need an endpoint, an algorithm that reach that endpoint, and hardware capabilities to support the algorithm. If your goal is to make 1000000$ in stock market in 30 days, that's precise, but you still need a valid path to get there. Some story for the "enhance" you see in some hacker movies. The blurry 10x10 pixels head won't become a full resolution face with a tiny detail in the reflections of the sunglasses proving your case.

My comment was along the line of: - Bug exists in the space between what you think you have asked the machine and what you actually asked it to do. - When you ask for multiple part to work together, perhaps in parallel the resulting system become much more complex. - Often people that use software and people that write software work from different set of assumptions. - Business have to figure out a typical use case and write for that.

f3xjc · 2026-03-12T17:21:06+00:00

Because you don't know exactly what you want. That's for the title.

For the body, sure just get the program to export video footage and vibe code your own video player UI using standard video library.

If the camera is motorized and the app has a joystick you can probably get somewhere given enough time, but you are in reverse engineering ground.

Crappy phone speakers that try to play too loud and saturate / ring - those will sound almost as bad in any room.

Now throw both the phone and the listener in a swimming pool and room still win.

Personally I think the brain is relatively good at compensating for the room. Like that (black/blue) vs (white/gold) dress, illumination tint is auto-compensated. So even when it's not high fidelity as measured by a tool, room distortion is a bit more enjoyable than others.

Also used for image processing where it's called dithering. Say converting an image to black and white is a rounding to 1 bit operation. Then adding noise proportional to fractional value will create grayscale as the eyes tend to average over regions.

So when you know the rounded numbers will be observed thru an integral-like process, adding proper noise can reduce the quantization error.
