@avrldotdev Keep going until you can live for free, providing for your family with open technology.

Software engineers, what's your plan when AI develops better taste & architectural/systems knowledge than you in next 3-4 years?

@facontidavide Still salty that jFrog took down JCenter

Who do we have here?

@facontidavide but is it written in Rust?

#spoiler #WIP

@yacineMTB He's looking at this post

Outside a restaurant, I see a young man in cook's clothing squatting, scrolling his phone. Not too long ago, it would have been a cigarette break instead of a phone break Why is this stuff not heavily controlled? It is retinal fentanyl on tap. Our society is sick. Our children!

@WatakoLab Very nice work. Impressive frequency and latency. What detector do you use for the ball? We do a similar algorithm with YOLOv8 and ZED. We could track the 3D position of colored tennis balls just like this.

動画後半にて、認識状態をPCで可視化しています。 (PCでは可視化のみで、認識関連はすべてロボット内で処理) 可視化の内容は以下です。 ・黄/橙点: ToFセンサ情報 (VL53L5X) ・頭部Ray: ToFセンサ情報 (VL53L0X) ・赤い箱: 頭部カメラの画像認識とToFセンサ情報を統合して得られた物体の推定位置

地面にボールが置かれると、追いかけます。 動画後半に処理の可視化もあるよ。 (解説続く)

@yacineMTB @gurgle_io @gurgle_io you better patent that quick

@gurgle_io No. I was testing backflips. But actually I didn't even realize that the props could be used like that. You are a genius

I'm building the Canadian DJI with a debit card

@facontidavide It is 2.3 million points updated at 30Hz and we have run 3 of those simultaneously to compare logged sensors. We'll test 100 million but the important technical element is that it's using camera facing (fragment shader) "point sprites". Just little squares, scaled, and colors.

@duncancalvert 100 million points or its peanuts

Do you need to visualize humongously big pointclouds and your fancy Visualization is choking with it? I want to talk with you.

So maybe they aren't that large, I just checked and we don't do a history of point clouds like you're talking about, but ZED X Mini at full resolution and frequency works great: github.com/ihmcrobotics/i… github.com/ihmcrobotics/i…

@duncancalvert Good to hear. I will start soon implementing the 3D rendering pipeline of #PlotJuggler 4 and I want to benchmark it against the most demanding use cases.

@Escoeerg @facontidavide We had it working pretty well a few years back. Apache 2 youtu.be/j0T7PqXSP60

@facontidavide Fu*king Ouster OS1 hits 1Gbits at 128 Planes and highest resolution. Good benchmark. Also, it reaches about 85°C when running, don't touch it.

I'm a Doctor!

@yacineMTB Did you get audio over HDMI working?

It's incredible how much happier I am as a human being because I have a laptop that is running arch Linux. It's so stupid why am I like this? Yet it matters

@xwanyex It's more like 3X improvement and we would have been cooked without it.

@cammakingminds This would be using the ship trajectory as the reference frame, not the Earth.

If you are using the earth as a reference frame, the moon is actually doing a close flyby of Artemis II.

@yacineMTB What's up boys

ONLY HOT DADS IN TECH CAN REPLY TO THIS POST. YOU ARE NOT ALLOWED TO REPLY IF YOU AREN"T A HOT DAD IN TECH.

@yacineMTB @Jonath4nH Completely agree and it's easy for anyone to learn this themselves by just trying it.

@Jonath4nH this sort of disconnected way doesn't work. I have to understand everything wholly, its the only way I can tell which direction is worth going. Anything I do without understanding is a debt that I must pay 4 times over

It's remarkable how much of my work is completely automated w/ AI, and yet, I still am necessary. The amount of time I personally have to spend working just isn't going down. Instead, the leverage of my own time is going up. Every second I spend not working becomes more painful

@andrewkaluz everything in a computer is represented by text at some level. if you master the text, at the very least understand it, then your power increases by quite a lot

@yacineMTB Luckily LLMs are specifically trained to extract info from PDFs, even visual info

it is insane how much EE data is in a pdf. how is there not a common parsable format that i can grab. jeez

@yacineMTB @plasmarob I never attempted the basic and never finished anything until I was like 17. Then I started achieving the advanced more and more. Truth to this

@plasmarob no, they just need to be able to break down their big task into small tasks. if they give up they were never destined for greatness

something i learned from my wife, who recently learned how to sew: do not do beginner projects. if what you want to make is difficult to make, you should just try to make it. don't do a slow learning process. don't start with the basics. start with the advanced

@TeslaPatriot @radbackwards You are aggressive but kind of have a point. The light seems alright but I never worked under one. Point lights are the worst. I would expect this creates decent shadowing. Sky lights are the best.

@radbackwards I don’t respect your vague posting. I don’t respect aesthetic opinions presented as cautionary technical advice. I don’t respect everything that everyone I follow posts.

Whatever you do, don’t let the self-proclaimed ‘architect’ convince you these lights are a good idea
