When @aceottorney.bsky.social first told me about this I said "this could change people's lives and stop developers from getting exploited" and having seen the final resource, I think I was not wrong. I'd call it a must-bookmark for indie devs.

I had the same experience on the Oregon coast, where I met *trees* that were older than the USA. It really put my problems in perspective in a wonderful way.

Mhmm. When I come here, whatever latest post I see is a banger. If I am posting less these last few months, it’s because I’m existing in the real world, interacting in real life. I love a platform that isn’t trying to get me to spend more time on it than I want to.

Patty Briggs writes the excellent (my fav) Mercy Thompson series, and in it the police get antsy once people start carrying silver bullets b/c they’re essentially armor piercing bullets. Anyway, the author’s partner made some silver bullets from scratch and it’s a fun read.

Every time more bad, apocalyptic-sounding news comes on I ask myself “should I be paying off my debt? Or just hoarding the cash?” I know the world isn’t ending tomorrow, but it feels like it could be sometime in the next 10-1000 days.

I am happy with my collection here. The Namiki Capless is a good addition to the Mont Blanc 146 and Sailor 1911. I really like Sailor Manyo inks for their watercolor-like shading. Not pictured: 1948 Parker 51 with needlepoint nib (out for repairs).

Good reporting. I am in solidarity with BDS, despite having a son that loves Minecraft and a game design program that wants to play good video games.

I hate to post this today, with all the news, but the genocide goes before all. Microsoft confirms it is supporting the genocide with AI tech. Israel never does anything but hurt Palestinians in Gaza, so "it's not used to harm Palestinians" is bullshit.

#npd #NewPenDay I would talk about it on Reddit, but I prefer BlueSky. I love fountain pens, vintage even more so. This pen has been on my wish list for a few years, but out of my price range. This is really nice.

Pilot Namiki Vanishing Point <M> with Pilot Iroshizuku Tsuki-yo ink. A gift! from a new acquaintance. Very, very cool. And kind. It feels smooth, light, and solid.

After watching the difference between Israel bombing EVERY HOSPITAL in Gaza INTENTIONALLY for TWO YEARS STRAIGHT, and what seems like a Iranian stray missile hitting an Israeli hospital (which is bad, too!) - I'm done with Western media. This isn't journalism. It is complicity in genocide.

I dug up this very helpful old article on the internet archive that I think explains the problem and solution extremely clearly using the way Quake handles gravity as an illustration
web.archive.org/web/20160719...

Doing gravity right

Now you may be thinking: "baah, I know how to do gravity.." but there's a big flaw in the commonly used Euler's method to handle the gravity (or other forces). Even all the Quake games have this problem. Then what is it? If you have more frames per second in Quake, your player will run faster and jump higher. There are some places in Quake where you can't jump high enough if you don't have enough frames per second. Sounds odd, right?

Most of the programmers do the gravity something like this:

velocity = velocity + gravity*delta_time
position = position + velocity*delta_time

The algorithm above is ok but when delta_time changes or delta_time is too high, it causes many unwanted problems. Gravity adding should actually be done like this:

velocity = velocity + gravity*delta_time/2
position = position + velocity*delta_time
velocity = velocity + gravity*delta_time/2

That's it.. but you need proof, right?

Results in practice

Here is a "jumping" parabola with different delta times, using the bad algorithm. The picture on the right corresponds almost exactly to Quake. As you can see, you can't jump in Quake if you have less than 3 fps.

(Illustration showing changes in the arc of a jump depending on framerate)

As delta time (dt) gets higher, the jumping curve gets lower.

Now here are results with the new algorithm:

(Illustration showing the arc of a jump staying the same)

Quite nice, don't you think? Accelerating physics are no longer approximation!

Remember that you should do all the accelerating forces like described above, not just gravity.

Integrating to the same results

The proving of the formula can also be done using integration (of course, because you are calculating areas..)

After integrating you'll get this formula:

pos = pos + 1/2*acc*dt^2 + vel*dt
vel = vel + acc*dt

Note that pos = position, vel = velocity, acc = acceleration and dt = delta_time

And optimizing that formula leads to this:

temp = acc*dt
pos = pos + dt*(vel + temp/2)
vel = vel + temp

This equals to the second formula given at the beginning of this document.

Remarkable.

Seconds later, LA County sheriffs start firing on the crowd.

Yet again, "law enforcement" deliberately escalated.

An idle question of "Can I use unreal engine to build to the Apple Vision Pro?" led me to this incredible video by @ibrews.bsky.social. It's 8 to 20 hours of work pushed into 2 minutes. If you aren't building apps on a mac, this stuff takes forever. I am blown away - thank you Alex! So entertaining.

Yeah, those are big ones. Wanting to move out of the country to someplace that has a brighter future for my boys, the idea of losing all of the momentum that we have going for us here is… daunting.
