Halfanalysis wants to profile code with pdb... That's like trying to measure how fast a car is going by stopping it every few feet to ask the driver where he is

Great job strawmanning our tweet! We never said to replace Nsight with pdb. We said that for simple debugging tasks, tools like py-spy, pdb, or the PyTorch profiler may be good enough. Of course, for heavyweight profiling, Nsight Systems is needed. It's about choosing the right…



Brutal but imagine how many companies will have an ongoing code red for memory optimization. Great time to be an optimization swe.

64GB DDR5 prices have gone from $150 to $500 in less than 2 months

Nope, there is enough scope to bring down the headcount by 50% without much material impactm

Google got good at AI. They did not let bureaucracy kill them in the end. Bravo.



Agents are much faster than humans, so while horizon matters for experimentation, I am not sure code generation needs to be this long. The bottleneck will always be the human who has to review the generated code, and imv unless we do away with code reviews altogether -- this is…

We estimate that GPT-5.1-Codex-Max has a 50%-time-horizon of around 2 hr 42 min (95% confidence interval of 75 to 350 minutes) on our agentic multi-step software engineering tasks. This is also the longest point estimate for a time horizon that we have published to date.

Rage baiting engagement farmer!

Assertions in production code is just wrong.

No, unwrap() is not about "trust me bro", it's an assertion to enforce an invariant in the code. Yes, it's badly named, but saying unwrap() is a ticking time bomb is like saying assert is one...



people just make up random shit

It is @sundarpichai… he took a big swing and restructured the company in 2023 and put the one and only @JeffDean in charge of AI/Gemini and decided $GOOGL would focus on a single model… they also brought Noem back via CharacterAI. Combined Deep Mind and the Brain team… Google…



A more plausible scenario: @AnthropicAI acquires @thinkymachines soon-ish, and the combined entity gets acquired by @Google, a year down the line, when the bubble pops.

Another takeaway from the deposition: Mira Murati apparently gave all the evidence to Ilya, and imv comes across as someone who was pulling all the strings and played Ilya like a flute. This makes me wonder how many months before Thinking Machine gets acquired by Meta. I will…



Googleification of Java made it worse. It used to be such a nice language, but then as dynamic dependency injection got more popular, it became super verbose. If you have to reach for Java, then consider Kotlin instead. C++ is great within FAANGs but horrible outside -- another…

Java: You're trying to understand how some code works. Open a file, it's ~20 lines of trivial boilerplate and getters/setters. Open another, same. And another. And another. This happens like 75 times. It's legitimately hard to find a place where anything is actually being done.



Lol who tf is running this account

Google Engineers are not very good at optimisation. A bunch of basement dwellers beat them: x.com/FFmpeg/status/…



Wishing another 16 years of accomplishment to the best language out there! go.dev/blog/16years


This has been the common understanding amongst all major labs, building a browser automation agent, for at least an year now.

When we got started, we figured DOM, HTML, etc. must surely be the right way to build web agents. After all, the visual rendering of a website is meant for human consumption. Why must a machine use that over the underlying machine code? We were wrong. Over time, the web will…



Waymo has done phenomenally well over the past one year. With a fleet of just 2500 vehicles, they are currently at 1M rides per month, or ~13 rides per day per vehicle. But that sounds like the cars are heavily underutilized, operating at 35% capacity -- assuming 300 mile…

Big day — we’re starting to rollout freeway driving for public riders in Phoenix, LA, and the Bay Area. We’re also connecting SF to San Jose, and adding curbside access to SJC Airport. A true testament to the generalizability of the @Waymo Driver. Excited to bring its proven…



Thanks for the homework!

Excellent piece: “The real divide in our economy isn’t between rich and poor, but between those working to get us out of economic malaise and the legacy incumbents happy to keep coasting on the rents of stagnation”



At Google, any L4 can easily deploy a production quality rpc service within 3-7 days of wall clock time. And, it's substantially well measured metric. Of course, if you wanna expose the service to public -- you need many more days of reviews.

Every company should create an internal benchmark measuring how hard it is to create a simple regional CRUD service and publish it to production with bare minimal privacy, security, compliance, and observability features in place.



Didn't bezos lead a large funding round in perplexity? Weird

NEW: Amazon sent a cease and desist to Perplexity demanding it stop letting allowing its AI browser agent, Comet, to make purchases online for users. Perplexity is pushing back, accusing Amazon of bullying a smaller competitor and limiting user choice. bloomberg.com/news/articles/…



The crazies part of Ilya's deposition is that he doesn't know who is paying his attorneys. He guesses it must be OpenAI but this was the weirdest part in my pov. If someone was my attorney, I would make sure they are on my payroll.

Sam Altman to Elon: I turned OpenAI into what it is today, get over it.
