Built an interactive course teaching systems programming by building real production systems 🔥 12 lessons: HTTP servers → Concurrency → Distributed systems Try it: [https://t.co/8ZKXl1hi34] Build it: [https://t.co/0AjQSoHt6B] #buildinpublic #SystemsProgramming

@edusoyy Elon saying 3 years, it meams we have atleast 30 left lol

[Kapil Jain @JnKapil]

@trq212 For me what works is explain the fundamentals first and then explain from bottom up!

[Kapil Jain @JnKapil]

@GaryMarcus @geoffreyhinton Should LLM be called AI at all?

[Kapil Jain @JnKapil]

@ChShersh Team lead improves? Lol

[Kapil Jain @JnKapil]

Lately, I keep building custom apps with the help of AI. For example, I wanted a custom program for my knee pain, and another one to track my sleep. Within 15 minutes of back-and-forth with the Claude AI app, I had apps installed on my iPhone.

[Kapil Jain @JnKapil]

@shanselman It’s true with every hard task or project. You just need to keep moving every day!

@Hadley What does cursor not have that other AI tools have?

[Kapil Jain @JnKapil]

@rambling_kiwi @minordissent Didn’t Jensen say that the AI models need more chips to run not necessarily nvidia gpus?

[Kapil Jain @JnKapil]

@simonw @olson_dan Since april 2025 infact

[Kapil Jain @JnKapil]

@simonw I never had this concern after 2025 april when agents were able to run the tests and figure out why were any failures. I was not working on crud projects but complex c++ codebase processing millions of requests per sec.

[Kapil Jain @JnKapil]

@bcherny Are you making it like cursor now?

[Kapil Jain @JnKapil]

@Steve_Yegge You can be agentic power user with cursor also. It can do everything that claude code, and more!

[Kapil Jain @JnKapil]

@copyconstruct @intensivedata I didn’t feel there were substantial changes from previous edition except addition of k8 and cloud related stuff.

[Kapil Jain @JnKapil]

@Grady_Booch Agree with you Grady. There are so many nuances involved and it needs human oversight. I feel he is out of touch!

[Kapil Jain @JnKapil]

@steipete I was in your camp earlier- always talk to model to plan. But recently have started playing out with plan mode first. I think mainly because UI asks nice questions sometimes which i find useful.

[Kapil Jain @JnKapil]

@gvanrossum You missed the loop!

[Kapil Jain @JnKapil]

@waronweakness Experienced it during and especially after covid — here it felt like like you couldn’t walk out your house without an n95, when in reality everyone else is roaming around freely as if covid never happened!!

[Kapil Jain @JnKapil]

@waronweakness Or maybe you are in an echo chamber??

[Kapil Jain @JnKapil]

@karpathy @nvbkdw @nummanali Ask agent to ssh. I run from my local mac and ask it to ssh to other boxes itself.

[Kapil Jain @JnKapil]

@Nova28ax @claudeai They don’t take human out of the loop. They will reinforce the same patterns and problems even with review :)
