🚀 ScaleUp by JioHotstar | Deep Tech Meetup

Hey everyone! I’m super excited to share that we’re hosting ScaleUp by JioHotstar, an in-office tech meetup where our engineers (including @PracSharma, @jiten, @cereal_learner) will talk about how we build and operate systems that power millions of concurrent users across the globe.

This is where we’ll go behind the scenes of video streaming at scale… the systems, the decisions, the trade-offs, and a few battle stories from production 😄

📍 BLR | JioHotstar – PTP Office
📆 16th January 2026, 5:30 pm
🎟️ Limited seats | No walk-ins

- Registrations are open for engineers, builders, and tech enthusiasts who love deep tech conversations.
- Profiles will be screened before we send out the final invites.

💡 Why this matters:
If you’ve ever been curious about how large-scale streaming, personalized recommendations, or dynamic ad systems work under the hood… this is your chance to learn, connect, and discuss with the team that builds it!

👉 Register to attend: https://t.co/W8KxRFI7a2

Let’s meet, learn, and geek out together — this one’s going to be special! 🙌

@AsfiShaheen Thanks 🙌

@AsfiShaheen I have good experience with DSPy and some with GEPA but felt that the current way of improving tool call usages/descriptions is bit hand wavy.

[Gaurav Kumar @cereal_learner]

So many people give over-emphasis to knowledge. It can easily be attained, especially in today's world.
In my experience, I always prefer Agency >> Skill >> Stack familiarity
If the candidate has high agency, they will be able to acquire any skill and learn any tech stack.

Interviewed a frontend dev yesterday with 12+ years experience.

Didn't know about Suspense boundaries in React 19. Struggled with explaining useTransition. Never used Server Components.

But when I asked him to debug a performance issue, his approach was brilliant. Asked the right questions, broke down the problem systematically.

Hired him on the spot.

Experience isn't about knowing every new API. It's about knowing how to figure things out.

@lateinteraction @tech_optimist Simplest way is to think of it like ProgramOfThought module but applied to prompts as well

Hyrum's Law: with a sufficient number of users of an API, it does not matter what you promise in the contract: all observable behaviors of your system will be depended on by somebody.

Making Postgres connections faster broke implicit rate limiters!

We are incredibly sorry for our downtime this week. The incident is now fully resolved and we have published a postmortem, including root cause and remediations.

We at @tursodatabase have just done something unheard of in the startup world: we hired a person in prison. Not an ex-con: he is actually serving time right now.

If you follow us you may remember when we announced our full rewrite of SQLite in Rust, Project Limbo. It got a tremendous amount of attention, but by far, my favorite story was that of @PThorpe92: Preston is currently incarcerated for things he regret doing a decade ago. A model reformed inmate, Preston was given the beautiful opportunity by the Maine Department of Corrections to access the internet. He then found our project, and since it's not like there are many entertainment options competing for his attention in prison, he decided to pour his heart and soul into helping us rewrite SQLite.

I immediately fell in love with his story. Reading his old blogs, his Github profile. I prayed we would be able to hire him as soon as he was out, and make him a part of our team. But thankfully, things have happened in such way, that we were able to do it *even before* he was released. He's now given an opportunity to make a dent in the world, from prison.

Preston claims he is immensely thankful for this opportunity. It is certainly not an opportunity that comes often, and I understand him.

But when I read his story in his personal blog, where he mentioned how he clearly saw his life going downhill, had this sudden epiphany, saw clearly that he could do differently, and then started being showered with blessings, I saw the unmistakable markings of how our Lord Jesus Christ, the Lamb of God, operates in the world.

I was an obnoxious Richard Dawkins-style atheist for more than two decades. I am not an experiential person, and I came to a change through the rational evaluation of the historical context of His resurrection. I am not the kind of person that feels the hand of God in my life, but over the years I learned to recognize his patchwork through those sudden, unexpected changes, where everything suddenly "just works".

And because of that, I am the one who's thankful. The Lord decided to operate such a drastic change in Preston's life. Clearly He has a great plan for him. I am immensely thankful for the opportunity to play a small part in that story. God, in his infinite power, doesn't need me to do any of that, and yet he gave me the opportunity to act. I feel thankful and blessed.

I am also very thankful to @LabsUnlocked , and entity helping people like Preston find a better life once they're out. If you feel inspired by their mission, you should reach out and help.

And if you want to hear from Preston in his own words, read the article he just published on the Turso blog:

@d4m1n Deepseek had a lot of thinking in Chinese actually. When doing deep thinking, it would turn to think in Chinese and then finally comes out to give the conclusion in English again. Likely because it was trained on such a training set.

[Gaurav Kumar @cereal_learner]

@jasonfried Let's move this to backlog and we'll prioritize it later ... and other lies we tell ourselves

Can someone recommend a good UUID?
I've searched a lot and a8098c1a-f86e-11da-bd1a-00112444be1e seems pretty random. Want to make sure no one else has used it before!

[Gaurav Kumar @cereal_learner]

@shuttle_dev End to End it takes a lot of time.
I mean, deploying is easy but first we have to rewrite it in Rust

[Gaurav Kumar @cereal_learner]

@github WHY?
