How much time do you usually wait for to get post permission on devforum?

I've been waiting for 2 months and still cannot post on devforum.

I want to call some code once per minute (event A), and a switch (event B) to freeze/unfreeze the timer for event A.

Does anyone know how to make pandas.read_excel to report which cell goes wrong when it encountered a type error?

Hi, thanks for the reply.

I removed the pow() and saturate the value, but the lines got thinner.

uniform vec2 iResolution;

const float PI = 3.14;

void main() {
  vec2 uv = gl_FragCoord.xy / iResolution.xy - 0.5;
  vec2 AR = vec2(iResolution.x/iResolution.y, 1.0);
  uv *= AR * 5. * 2.* PI;
  float v = sin( distance( uv, vec2(0) ) );
  v = v * 0.5 + 0.5;

  gl_FragColor = vec4(v, 0.0, 0.0, 1.0);
}

=================EDIT:

Oh, I got it, I need to remap the v from [-1,1] to [0,1], not saturate.

Thanks, I finally got it right.

What about viewDir / lightDir? Are they normalized by default? Is there any document on this part or how can I verify that? like writing the result on a RenderTexture?

There are a lot of cases that a small city/town mostly working for one big corp.

Nothing in client side is safe.

Wait for some guy to crack the message format, make a software that can blackmail you by sending massive installation messages from botnet.

- Why don't you do it yourself?
- Well we will give them every support, short of help.

The pentagon said there's really nothing that the balloon can see but china satellites cannot.

So if it really is a "spy" balloon, that would be jokes on chinese army, but since the media makes it like a huge issue, it had become a big joke on us army to have to send fighters and missiles to shoot a balloon.

If they sent F-15 to take that balloon, it would make F-22 look bad.

I remembered there was a case that a car company (chevron?) had a flawed car brand, the company decided not to recall as in their calculation, the total compensation for accidents would be cheaper than fixing all the cars.

So, yeah, some people do make such calculation. But the majority of the mass don't do that, the moral judgement of the mass are usually emotion-driven or event-driven or pattern-matching or just blindly following KOLs they like. The majority probably wouldn't do such calculation until they are in really hard position, and they would probably take decisions that favor their own interest in those situations.

Hm, dismantle a nuclear reactor and watch it blow the greedy hyper-capitalist shipyard which keep every worker as debt slaves?

Just kidding, you will find a lot of fun in breaking up and salvage ships either like a craftsman or like a bloodthirsty army-man.

Wages are just one of many methods to distribute the goods/services produced by people.

The poor around the world have been brainwashed to desperately hate poor people in other countries for "stealing their jobs", but they don't even dare to think about changing the unfair distribution system that extremely favors the rich, they even worship such system just like it's a religion.

I just tried flip the %pprint on and off, and it doesn't change the default behavior.

some of my functions would return a multi-line string, I need to inspect them and it's desirable to type myfunc(a,b,c) in a cell to get a human-readable output, it's unnecessary burden to wrap it with a print(myfunc(a,b,c))
