TomVDB··on Nvidia Kaolin Wisp: a PyTorch library to work with neural fields
Researchers have a strong need for cross-platform compatibility?

Why waste time porting something to a different platform when the platform of choice already has a ready made script?

I’ll admit right away that I know nothing about the subject at hand, but browsing a bit through this repo, we’re most definitely not talking about 200 trivial lines of code…

TomVDB··on Sorry, your wife is Indian, landlord won’t rent to you
Was surprised to see “Singapore”, expected “Bay Area.”

When I left my last rental after buying a house, my elderly white landlord asked me to help him put the property on Craigslist. When I did so and mentioned the Cupertino school district, he asked me to remove that part because “it would attract too many Indian families with kids” to avoid the curry smell. He had no issue with other Asian ethnicities, the previous tenant was Chinese.

I did not remove it, but I don’t know anything about the next renter.

I’ve since heard the same comment from people at work who rent out property. The curry smell is always the issue.

TomVDB··on Will Intel's AXG division survive Pat Gelsinger’s axe?
One of the big attractions of CUDA is not just the core (programming, API, compiler, development tool) but also the libraries (cuDNN, FFT, cuSignal, … It’s a very long list). These libraries are usually not open source, and can thus not be recompiled even if you have core CUDA support.
TomVDB··on Ask HN: Is living in NYC worth it?
I used to live in NYC in my late twenties/early thirties. I was single, I made very good money, I loved it. For a man, it’s a great place for dating too, with a significant surplus of women.

But I also don’t regret moving to the Bay Area at all, where I enjoy living in a large house on a quiet street, close to the hills, with year-round great weather. I don’t have a desire to go clubbing anymore, a neighborhood BBQ is just fine.

It was much easier to make friends in NYC, but friendships were transient too: there’s a lot of coming and going. It gets exhausting after a couple of years. I still like going back once a year or so, but a long weekend is enough.

TomVDB··on California DMV accuses Tesla of falsely advertising Autopilot and FSD features
I wouldn’t trust FSD at all and there’s no way I’d ever pay for it, but I love autopilot.

What are Tesla falsely claiming about autopilot?

TomVDB··on Nomad drained of $150m due to a coding mistake
The first challenge is to find those normies.

Somebody who directly invested in MBS is by definition not a normie.

TomVDB··on How GPU Computing Works [video]
Starting with Volta, Nvidia GPUs have forward progress guarantee, preventing lockups when there’s thread divergence.

That doesn’t improve the performance of a well behaved and well written compute shader. But avoiding hard hangs IMO deserves the label “improved thread divergence.”

TomVDB··on How GPU Computing Works [video]
Nvidia GPUs were 32 threads per warps eight from the start of CUDA with the 8800 GTX.

> which I think is a terrible feature <> those are _really_ helpful but expensive

Guaranteed forward progress is a direct consequence of having an instruction counter per thread???

Or so I thought. How else would an SM be able to know the PC of a group of threads that wasn’t stuck?

TomVDB··on How CUDA Programming Works
I honestly have no idea what message you’re trying to convey here…
TomVDB··on How CUDA Programming Works
I don’t know which features you’re talking about, but over the years, CUDA has received quite a bit of features where Nvidia was quite explicit that they were not for performance, but for ease of use. “If you want code to work with 90% performance, use this, if you want 100%, use the old way, but with significantly more developer pain.”

Seems fair to me.

TomVDB··on Meta slashes hiring plans, girds for 'fierce' headwinds
How did you get to the conclusion that anyone thinks they’re entitled to that information? Of course nobody is.

But that doesn’t change the fact that it’s this information is useful for outsiders, not a disservice.

As for wanting leakers to be dragged into court…

Are you saying, for example, that Amazon warehouse workers should not be allowed to expose terrible working conditions? Or pretty much any other unethical action of a company?

Because that’s exactly what you’re advocating for.

TomVDB··on Meta slashes hiring plans, girds for 'fierce' headwinds
Why a disservice? It’s the contrary.

Thanks to those kinds of leaks, I had already decided I’d never want to work for that place.

When a good friend started working there, he confirmed pretty much everything.

TomVDB··on Meta slashes hiring plans, girds for 'fierce' headwinds
That’s de facto my situation.

After copy-and-pasting the same answers year after year in the self evaluation form, my manager got the message. That was, what, 10 years ago?

Now, once per year, we have a 20min meeting, he tells me “good job”, gives my new salary and RSUs, and we’re good.

It’s great.

Performance Summary Cycle.

It's a thing where you get performance reviews every 6 months, and where every minute contribution gets scored. Or so I've been told by a former mid-level Facebook manager who quit after a bit more than a year because he couldn't stand that toxic place anymore.

I found it particularly funny that the interviewers who gave the thumbs up to hire him would get bad marks because of his early departure.

TomVDB··on Electric fan car shatters the Goodwood hill climb record
F1, cycling, soccer, NASCAR, cricket, …

They all have their fans and their critics who think it’s a boring sport.

I don’t follow F1, but based on a bunch of people in my Twitter feed, they finished one of the most exciting seasons in years.

TomVDB··on Keysight UXR 110GHz Oscilloscope Teardown [video] (2018)
I have clones and I have the real one.

The clones are a copy of the Saleae units from 10 years ago. They’re not at all comparable to the current high-end ones.

One of the killer features of the current ones is the ability to also record an analog trace. It’s fantastic when you need to record minutes of something that misbehaves electrically every once in a while.

TomVDB··on Ask HN: How did you find your current job?
LinkedIn, but as a passive agent, many many years ago.

My colleague interviewed and got hired. The hiring manager contacted through all his relevant LinkedIn relations.

They exist!
TomVDB··on A vase kept in an ordinary kitchen turned out to be a Qing-dynasty artwork
$1.8M is not bad, but the article also brings up a similar case in 2010 where a vase found when cleaning up a house was estimated to be worth $2M but was eventually sold for $83M?!?

https://www.spokesman.com/stories/2010/nov/13/familys-old-ch...

Edit: it gets better. That $83M was never paid by the buyer in what may have been a protest organized by the Chinese government against the sale of looted treasures by the British. Meanwhile, the sellers were in the hook for a $14M estate tax that was based on the auction price.

TomVDB··on Broadcom to acquire VMware for $61B
Absolutely not.

You’re thinking that Broadcom acts as a company with a technological vision. This is a totally not the case and the CEO is very open about that.

Today’s Broadcom is a company that optimizes the financial performance of technology assets.

There are no long term plans.

TomVDB··on Broadcom to acquire VMware for $61B
After being acquired by Avago, Broadcom ceased to be a single company. It’s a conglomerate of entities/BUs that are explicitly asked to NOT work cooperatively, so that each entity can be sold at moment’s notice if it doesn’t deliver the right financial results anymore.

Chances are that the current leadership doesn’t care about how VMware operates, as long as it cuts enough costs to increase metrics that Wall Street considers important.

Expect major cuts in R&D, receptionists, travel expenses, general benefits, and virtually no hiring of college grads or interns. You’ll be on the phone in a queue for hours to get outsourced IT support.

Support of open source should be the least of your worries.

Stock price might go up though…

TomVDB··on Nvidia releases open-source GPU kernel modules
I wish my company were in the same desperate situation as Nvidia. One where we’d be faster than the competition with similar perf/W while using a much inferior silicon process…
TomVDB··on Nvidia releases open-source GPU kernel modules
Turing is not the most recent generation of cards.

But that aside, Turing is their first generation that a GPU System Processor (GSP) that runs the heavy binary blob that comes with the open source driver.

TomVDB··on Passenger with “no idea how to fly” lands plane after pilot incapacitated
Yes, it would be very helpful.

My instructor encouraged me to buy MS FS, pedals and a yoke.

TomVDB··on Passenger with “no idea how to fly” lands plane after pilot incapacitated
Frankly, I’m not super surprised? I had a few hours of flight instruction before I dropped out (it just didn’t fascinate me), and what struck me was that you’re doing a landing during the first lesson.

As long as the landing strip is long enough, you can take things very slowly.

TomVDB··on 2021 MacBook Pro users complain about crackling and popping audio issues
Who knows?

I’ve seen cases where a functional block of an SOC got used one generation to the next without even seeing an issue.

And then suddenly, due to changing boundary conditions, a bug got triggered.

I’ve similarly seen cases where HW bugs were known but SW workarounds where calculates to reduce the chances of them manifesting themselves to be low enough. Until they suddenly didn’t.

The state space of HW is incredible, and it’s often not possible to foresee or understand the interactions between of SW and HW.

TomVDB··on 2021 MacBook Pro users complain about crackling and popping audio issues
They are complaining about it… That’s why it’s here on the front page of HN.
TomVDB··on 2021 MacBook Pro users complain about crackling and popping audio issues
As a HW designer who over the years has deal with many HW bugs, it’s amusing to see how almost everybody is agreeing that it’s a software issue “because it goes away when I restart or when I close this or that application…”

As if SW applications that stress the system in some way are capable of triggering a HW bug?

And if the issue eventually does get solved with a SW update, then it most definitely was a SW bug, because software update that work around a HW bug aren’t a thing.

TomVDB··on How Apple overcame its culture of secrecy to create AirPods Pro
One thing I love about my company is that most information is not siloed. There are product lines that I have no business known about, but I have access anyway.

It’s not only exciting to know what’s cooking in ankthwr group’s kitchen, it’s also great when experts from other teams volunteer to help when you’re stuck on a problem that’s their domain.

In larger companies, knowing what others are working on makes it a lot easier to find experts at something. And I’ve never experienced any of them being reluctant to share due to fear of disclosing information about the products they’re working on.

I don’t think I’d feel at home at Apple.

For me, the killer feature of Strava is… veloviewer.com.
