I work at Tesla, but speak for myself. Opinions are my own.

Performance of high-scale/low latency systems, counter-censorship systems, embedded systems, distributed VR systems, web browsers, compilers, some kernel work, even the occasional webapp.

lallysingh··on GPTZero finds 100 new hallucinations in NeurIPS 2025 accepted papers
On the bright side, an LLM can really help set up a reproduction environment.

Perhaps repro should become the basis of peer review?

lallysingh··on Ask HN: Anyone have a good solution for modern Mac to legacy SCSI converters?
How well did you terminate the scsi chain?
lallysingh··on There's a ridiculous amount of tech in a disposable vape
My first guess was debouncing. They assume that the switches are worn out, deeply weathered, and cheaply made. Each press will cause the signal to oscillate and they're taking their sweet time to register it.

When the device is new this is an absurd amount of time to wait. As the device degrades over 10, 20 years, that programming will keep it working the same. Awful the entire time, yes, but the same as the day it was new.

lallysingh··on Opus 4.5 is not the normal AI agent experience that I have had thus far
Yeah. Just like another engineer. When you tell another engineer to build you a feature, it's improbable they'll do it they way that you consider "right."

This sounds a lot like the old arguments around using compilers vs hand-writing asm. But now you can tell the LLM how you want to implement the changes you want. This will become more and more relevant as we try to maintain the code it generates.

But, for right now, another thing Claude's great at is answering questions about the codebase. It'll do the analysis and bring up reports for you. You can use that information to guide the instructions for changes, or just to help you be more productive.

lallysingh··on Ford kills the All-Electric F-150
I don't understand this comparison. An EV's battery cooling system is a cooling system. Regen braking isn't more complicated than an alternator.

The rest, yeah. The chemical stacks in the batteries are expensive, and dealer markup was a problem (now they're 47-56k new). But the energy costs! $7-12 for a fill-up on home power overnight instead of $75-85 at the gas station.

And maintenance. So little maintenance. For local non-towing fleets these would save a lot.

lallysingh··on The C++ standard for the F-35 Fighter Jet [video]
Yet the largest codebases I know of are either C, Fortran, or C++. Who's doing anything really big (in terms of LOC) in another language?

Go was made because Rob Pike didn't want to do Java.

No they won't. DoD is small compared to the rest of the software market. You get better quality and lower cost with COTS than with custom solutions, unless you spend a crap ton. The labor market for software's no different.

Everyone likes to crap on C++ because it's (a) popular and (b) tries to make everyone happy with a ton of different paradigms built-in. But you can program nearly any system with it more scalably than anything else.

lallysingh··on Valve reveals it’s the architect behind a push to bring Windows games to Arm
I always interpreted that as cosmetics are OK because it doesn't make the game unfair. You can't buy advancement in the game that way.

Subsidizing the game's devel/ops cost isn't a bad thing. Especially if it's optional and doesn't change the game.

lallysingh··on Valve reveals it’s the architect behind a push to bring Windows games to Arm
Slowly getting their stuff independent of wintel gives a lot of flexibility. And the big gaming market's on phones / tablets. A steam controller could find itself paired to an iPad running steam in a year or two.
lallysingh··on Valve reveals it’s the architect behind a push to bring Windows games to Arm
Microsoft's a competitor. And they have a reputation for being the first ally to stab you in the back (e.g. SGI / DirectX). You don't want to depend or trust them when they like the market you're in.
lallysingh··on India orders smartphone makers to preload state-owned cyber safety app
The way for the community to fight this is to keep finding holes in the app until they stop trying to put one on.
lallysingh··on India orders smartphone makers to preload state-owned cyber safety app
Yeah this is the wrong audience for this argument, but it has merit. An app like this can be both a massive government power grab and useful to protect many, many people who are vulnerable to fraud.

The number of my relatives that will just believe whatever someone tells them on the phone is terrifying.

lallysingh··on iPhone Pocket
This is an iPhone Thneed.
lallysingh··on America is getting an AI gold rush instead of a factory boom
My guess is that investors expect AI to automate manufacturing, and are waiting to see where that tech goes before spending a ton of capital on soon-to-be-obsolete machinery.
lallysingh··on Safe C++ proposal is not being continued
Call me stupid for asking, but what is "safe" here? I get the length-checked buffer copies and accesses, is there anything else? Less allowed type conversions?
lallysingh··on Samsung taking market share from Apple in U.S. as foldable phones gain momentum
Your eyes can skip around and read a lot faster. Most things I read have me skipping around quite a bit. The only time I'm straight-linear with reading is in fiction, and for that I've moved to audiobooks.
lallysingh··on Samsung taking market share from Apple in U.S. as foldable phones gain momentum
I had a fold 3, and now a fold 6. The screen protectors are easily replaceable yourself. It's the only weakness on the phone I've found, and a cheap ($17ish) wear item. The replacement ones I get feel much nicer and thicker than the original.
lallysingh··on Will AI Replace Human Thinking? The Case for Writing and Coding Manually
Hard disagree. We'll be able to use more expressive languages with better LLM support for understanding how to express ourselves and to understand compiler results. LLMs are only good at stuff that better languages don't require you to do. After that they fall off the cliff quickly.

LLMs are a communication technology, with a huge trained context of conversation. They have a long way to go before becoming anything intelligent.

lallysingh··on Google has eliminated 35% of managers overseeing small teams in past year
I remember TLMs being considered a bad idea in 2010. Looks like the pendulum took a full swing in the mean time.
lallysingh··on Pixel 10 Phones
It ran emacs. It was glorious.
lallysingh··on French firm Gouach is pitching an Infinite Battery with replaceable cells
How many cycles does the ebike battery go through in 200k+ miles? An EV car does ~300 miles/cycle. So 200k miles = 667 cycles.
lallysingh··on The circular economy could make demolition a thing of the past
I wonder if advancing robotic tech can help in the disassembly/reassembly process. Stuff that isn't cost effective right now (e.g. removing drywall sheets for reuse) could be replaced with things that are cost effective when it's cheap robot labor doing it.
lallysingh··on AMD CEO sees chips from TSMC's US plant costing 5%-20% more
They required unreasonable things from the compiler for instruction scheduling.
lallysingh··on XBOW, an autonomous penetration tester, has reached the top spot on HackerOne
I think a better one would be the average compute cost for xbow per exploit found, if you're interested in the shift in security economics this represents.
lallysingh··on Tesla seeks to guard crash data from public disclosure
The model Y was the best selling car in the world last year: https://www.statista.com/statistics/239229/most-sold-car-mod...

That's a lot of flaunters.

lallysingh··on Google AI Ultra
$250 a month. Oh my.
lallysingh··on Gemini 2.5 Pro Preview
The software tool takes a higher-level input to produce the executable.

I'm waiting for LLMs to integrate directly into programming languages.

The discussions sound a bit like the early days of when compilers started coming out, and people had been using direct assembler before. And then decades after, when people complained about compiler bugs and poor optimizers.

lallysingh··on Matt Godbolt sold me on Rust by showing me C++
Culturally, I think C++ has a policy of "there's no single right answer." Which leads to there being no wrong answers. We just need more answers so everyone's happy. Which is worse.
lallysingh··on Home washing machines fail to remove important pathogens from textiles
I'll wager the ones that do the poorest job in removing pathogens are also the most power and water efficient. Trade-offs matter.
