@RoboticswithV @nvidia @nvidiaomniverse Damn, can’t believe I missed this! Will keep an eye out on discord for the next one!

[Spurthi @bitsofspu]

@knowShubhangi This is awesome!

[Spurthi @bitsofspu]

@VazeKshitij They have an amazing podcast as well! It’s what got me into embedded systems all those years ago. I used to listen to the episodes on my way back home from college.

[Spurthi @bitsofspu]

@KuphDev True! That’s a good suggestion, I’ll try that placement. Thanks

[Spurthi @bitsofspu]

Meet my new beast - my first PC! 😁

Ryzen 9900X + RTX 5080 ⚡️

Super excited to dive into ROS, Isaac Sim, and build some coool robots! 🤖

[Spurthi @bitsofspu]

@pharmersunil Yessir! 🫡

[Spurthi @bitsofspu]

@iuliaferoli Oh no, that sounds so frustrating! I haven’t reached that step yet, I’ll let you know when I get there. Did you try the docker container method with 24.04 as the base OS?

[Spurthi @bitsofspu]

@vbwanere This was one of my top options too. I ultimately went with the 5080 for the extra parallel processing power.

I’ll share updates and my thoughts on this combo as I test it out.

[Spurthi @bitsofspu]

@KuphDev Cool setup! Haha, I went with Lian Li 217 + Arctic Liquid Freezer to try and optimize airflow. Hoping mine doesn’t turn into a space heater too🤞😂

Love seeing your robotics journey, especially that duck-picking robot! Such inspiring and fun stuff! 🤘

[Spurthi @bitsofspu]

@nerdytanay Absolutely, I’ll share updates as I set it up and test Isaac Sim

[Spurthi @bitsofspu]

@johnfurr538500 Haha thanks John! May the odds (and the robots) be ever in my favor 🤖

[Spurthi @bitsofspu]

@JioCare I have sent you a DM with the details

[Spurthi @bitsofspu]

JIO MAJOR DATA BREACH! You just installed an un-wiped, used JioFiber STB in my mother's home that still has a stranger's full profile and active OTT accounts logged in. Exposing customer data like this is an absolute security disaster. (1/3) @jiocare @reliancejio @TRAI

[Spurthi @bitsofspu]

I refuse to accept this compromised, recycled equipment. Send a technician to my Bengaluru residence IMMEDIATELY with a BRAND NEW, factory-sealed STB. Fix this account mapping instantly or I will escalate this privacy violation to the consumer forum. (3/3)

[Spurthi @bitsofspu]

The previous owner's Netflix, YouTube and Hotstar are wide open. Are your technicians bypassing warehouse QA and just swapping un-wiped hardware between homes to cut corners? Handing out someone else's digital life to new customers is gross negligence. (2/3)

Last summer, I craved Indian mangoes so much in Boston that I paid $10 for one mango. Totally worth it!!

Thankfully, I’m in Bangalore now, and I can have as many mangoes as I want xD

[Ram @ramprasad_c]

You can get a good banana anywhere in the world. Good strawberries, good apples, good peaches, good melons, good grapes. Walk into a grocery store in Tokyo, London, Sao Paulo, or Stockholm and you will find perfectly decent versions of these fruits. They travel well. They grow in many climates.

But a good mango? That is only India. I don't mean a mango-shaped fruit. South America grows those. Florida grows those. They look like mangoes. They smell like mangoes. They are not mangoes. Technically the same category. Practically a totally different experience.

The word itself tells the story. "Mango" entered English through Portuguese, who borrowed it from Tamil and Malayalam. Every language that uses this word borrowed it from India because that is where the fruit comes from. Even the scientific name, Mangifera indica, literally translates to "the plant that bears mangoes, from India." Over 1,500 varieties. Alphonso, Kesar, Banganapalli, Dasheri, Langra, Himsagar. Each one specific to a region, a soil, a microclimate. You cannot replicate that. My Dad put up a mango farm in Andhra, South India and planted Alphonso variety. Not the same as the ones from Ratnagiri in West India.

There is a lot of talk about increasing mango trade from India to the US. If it materializes, the prices in India could shoot up, Don't think Indians are dying to export mangos. It is not the most predictable crop anyway.

[Spurthi @bitsofspu]

@LadyAshBorg @CaptVenk is the best example of this!

[Spurthi @bitsofspu]

There’s actually a lot more to spiritual lectures than just teaching you to detest material success. A core concept of “Bhagavad Gita” is to do your duty without dwelling on the result. Follow the right teachings, and it’ll make you more ambitious, not less.

[Viraj Sheth @viraj_sheth]

my personal take on the youth immersing themselves too much in spiritual lectures from gurus and babas is that it softens you too much, makes you less ambitious, makes you detest material success.

when you’re young you should want to build things, contribute to your family and society, not think about hanging your boots to seek nirvana.

Aujourd'hui grosse discussion avec mes ingés (chez Argil) sur pourquoi Elon a viré le LIDAR de ses voitures autonomes. Choix radical, moqué pendant des années, et comme d'hab il avait raison depuis le début.

Le LIDAR c'est un laser qui balaye l'environnement et crache un nuage de points 3D. Sur le papier tu obtiens la géométrie exacte du monde. Dans la vraie vie c'est une verrue technologique collée sur le toit parce qu'on sait pas faire mieux avec la vision seule.

Problème numéro un : ça rajoute une modalité dans le training du modèle. Ton réseau doit apprendre à fusionner vision + lidar + radar + ultrasons. Chaque capteur en plus c'est une source de désaccord à arbitrer, pas une source d'info supplémentaire. Sensor fusion artisanale = dette technique permanente.

Problème numéro deux, la bitter lesson de Rich Sutton : scaler le compute sur une seule modalité bat systématiquement les architectures bricolées à la main. Tesla a dropé le radar, puis les ultrasons, est passé full end-to-end vision. Leur courbe sur les edge cases s'est accélérée APRÈS, pas avant. Waymo fait l'inverse et reste stuck en ops géofencée.

Problème numéro trois, le plus fondamental : le LIDAR voit la géométrie, pas la sémantique. Il sait qu'il y a un truc, pas ce que c'est ni ce que ça va faire. Les derniers 9 de fiabilité sont des problèmes de cognition, pas de perception brute. Un capteur de plus résout rien, il ajoute du bruit.

Sébastien Loeb balance une 208 T16 à 180 dans un chemin boueux corse sous la pluie avec zéro LIDAR. Deux yeux, un cerveau. L'évolution a donné des yeux aux prédateurs pendant 500 millions d'années, pas des lasers. Il y a une raison.

Le LIDAR c'est l'équivalent du marxisme appliqué à l'économie. Une solution planifiée, centralisée, qui prétend modéliser explicitement ce qui doit émerger d'un système distribué et adaptatif. Tu remplaces l'intelligence par de la mesure, la compréhension par de la donnée, l'émergence par le contrôle. Ça rassure les ingénieurs qui veulent tout spécifier en amont, exactement comme la planif rassurait les économistes soviétiques. Et ça échoue pour les mêmes raisons : la réalité est trop riche pour être capturée par un capteur, comme elle est trop riche pour être capturée par un plan quinquennal.

La vraie intelligence, celle de Hayek comme celle de Tesla, c'est de faire confiance à un système qui apprend de l'expérience plutôt que de tout pré-encoder. L'élégance d'une solution c'est son rapport signal sur complexité. Le LIDAR explose le dénominateur.

Défendre le LIDAR en 2026 c'est préférer empiler des hacks plutôt que résoudre le vrai problème. C'est de la feignasserie intellectuelle maquillée en rigueur d'ingénieur. Les mêmes gens qui défendaient les systèmes experts en 2012 contre le deep learning. Ils finiront pareil.

Never bet against end-to-end. Never bet against la simplicité. Never bet against Elon.

This looks soo good!

Large touchscreens in cars suck!

Give me them knobs, buttons and switches! 🎛️

[Sawyer Merritt @SawyerMerritt]

Ferrari has released a new video of the interior for its first ever all-electric car, called the Ferrari Luce.

It was designed with Apple's former head of design, Jony Ive, who recently said "a large touchscreen doesn't work in a car."

Car info:
• Four-door four-seater
• 122 kWh battery
• 330 miles of range (European rating methods)
• 1,000 horsepower
• 0-60mph: Under 2.5s
• Four electric motors
• OLED screens
• Guess cluster screen is made up of several layers. By cutting out holes in the upper layers, Ferrari created displays where the speedometer graphic is below the level of a physical needle, which is itself behind additional drive info and beneath a curved inset lens.
• Will have fake gear shifts
• Weight: 5,100 lbs
