Knotting who?

Who’s there?

ceil(M_PI)

It sure does but quake1 and quake 2 happened on matrices and Euler angles so there’s a long way you can go before even thinking the letter q.

Writing rasterizer by hand is an incredible fun exercise. Get some basic reading on the graphics, don’t do gpt first. You will never see games as you had before.

Culling faces is simple: you have geometry in camera space. Take a dot product between a surface normal and view direction vector and if it’s negative then the normal is pointing away from you and the face is invisible.

Proper techniques with occlusion and stuff are more complicated, such as painter algorithm or z-budgeting or others

You don’t need quaternions for affine transformations.

Bummer.

Alcohol and cotton pad or swap. Or something less fibrous if your like to have less lint to pick.

Well it’s maybe my second? Third? And I did it specifically to replace the thermal compound.

And it helped.

Before: watching hd video in full screen VLC launched system towards 92C and fan spinning up to 7k.

After: same load, temp around 72, cooler at 5…6k rpm. stress-ng for 5 minutes couldn’t heat it up by 90.

I also sprayed some lube on the cooler, more as an experiment.

I think it was worth it but also fun.

Yeah gotta agree. Got carried away with it a bit.

Mad emperor is mad, other news at 11.

Attention driven economy. All enterprises now behave like they had a field week at used cars salesmen retreat. You can’t sell unless the value proposition is grotesquely inflated.

P1: Printer not working again!

P2: Ah I’ll go tell that programmer guy

That company, probably

I… don’t know?

Feels like one of the last generations of bikes that could have been serviced without a fancy shop. I’m amazed by their durability.

By now they are reaching about 15 years, so for sure are hard as woodpecker lips. I’m slowly eyeing something more practical for city rides.

Solid advice. To my biggest surprise, only plastic exposed to sun started to break down. The rest of rubbery things, esp. those in the underbelly, are in acceptable condition, maintaining flexibility and integrity.

Oil, coolant, breaking fluids and strategic application of grease and light massages are next on. And break calipers. And chain. And sprockets. And…

This is fun as Lego.
