TomVDB··on White hat hacker awarded $2M for fixing ETH-creation bug
You’re wrong in many different ways:

- Long term vs short term

- different rates

- state capital gains taxes

In this case, with the receiver being a CA resident, he pays almost certainly more than 50% in taxes on this bounty.

TomVDB··on Tesla FSD beta crashes into object [video]
Making a car that has the highest crash safety rating has nothing to do with the safety of their FSD solution.
TomVDB··on Rails is not written in Ruby
I’m switching back from Ruby to Python out of necessity, and I loath things like len(my_list) vs my_list.len().

I just don’t understand why Python thinks it necessary to define global functions for something that naturally should exist as a method.

And, of course, there’s no way to know up front when to use a global function vs when to use a method.

TomVDB··on Tesla drivers report a surge in ‘phantom braking’
I’ve driven 15000 miles in the past year on my Model Y, a large part of it shuttling between the Bay Area and Reno, so mostly I-80. And many miles of autopilot.

So for, not a single phantom break.

So I wonder what it is that makes it not happen for me? Probably half of those miles are in the evening, so that might be a partial explanation. Maybe the direction from which the sun is coming?

TomVDB··on Over 10% of Tesla Model S EVs Fail Germany’s Strict Inspection After 3 Years
The suspension arm of my colleague’s Tesla broke. He showed me the broken part. It was something that should never break.

My other colleague’s Tesla had multiple major issues, including one that requires an engine to be replaced.

They both still bought a new Tesla after that, and so did I, because they’re just so fun to drive, but your anecdotal evidence doesn’t disprove a fact about a 10% failure rate.

TomVDB··on Simulation of a 2B-atom cell that metabolizes and grows like a living cell
I’m subscribed to some CUDA email list with weekly updates.

One thing that strikes me is how it evolves with new features. Not just higher level libraries, but also more fundamental, low level stuff, such as virtual memory, standard memory models, c++ libraries, new compilers, communication with other GPUs, launching dependent kernels, etc.

At their core, OpenCL and CUDA both enable running parallel computing algorithms on a GPU, but CUDA strikes me as much more advanced in terms of peripheral features.

Every few years, I think about writing a CUDA program (it never actually happens), and investigate how to do things, and it’s interesting how the old ways of doing things has been superseded by better ways.

None of this should be surprising. As I understand it, OpenCL has been put on life support by the industry in general for years now.

TomVDB··on A “Sideways” supply response in California winegrapes
I certainly can not taste the difference between any of them (and so do most others according to the article), but after Sideways there was definitely something in my subconscious that steered me away from ordering a Merlot.

I don’t think it’s sad at all, it’s a fun reminder about how we function.

TomVDB··on Toxic culture is driving the great resignation
I’ve done the roommating thing, and paid my dues living in small apartments. But at some point I wanted the comfort of a house with a garage, a hobby room, and a yard where the kids can run around.

So, yeah, different expectations.

TomVDB··on Toxic culture is driving the great resignation
Finding a job that’s fun and fulling and finding one that is very well paid doesn’t have to be a contradiction.

But there are multiple reasons why money is a bigger focus:

- less long term job security. And that lower paid fulfilling job might very well be less secure too. I want to secure my financials as quickly as possible.

- insane cost of housing. A family sized 1800 sqft house with a garden now routinely sells for $3M in my neighborhood. You’re looking at $120k per year in mortgage payments and another $40k in property taxes. That’s after a $750k downpayment.

- the cost of higher education for kids.

- the general cost of living.

We could all move to the French Riviera, I guess, or vote for a better system that isn’t a hellscape for a significant segment of the population, but for an individual who’s forced to live in the current reality, money is a short term fix.

TomVDB··on ‘I felt powerless – so I started filming’: CyclingMikey vs. dangerous drivers
You’re right of course. When I’m at a full stop in a never ending traffic jam on I-80, I’m totally a danger for not paying attention to the brake lights of the car in front also not moving.
TomVDB··on ‘I felt powerless – so I started filming’: CyclingMikey vs. dangerous drivers
Maybe hyperbole.
TomVDB··on ‘I felt powerless – so I started filming’: CyclingMikey vs. dangerous drivers
Yeah, if I’m standing completely still in a traffic jam, I’ll be glancing at my phone every once in a while, and nobody is going to convince me that this guy is doing a public service.
TomVDB··on What's it like to star in a flop?
I once went to opening night of Il Trovatore at the NYC Met opera. I thought it was great. At the end of the performance, singers for the usual ovations but when the director appeared on stage, the audience started booing. They apparently didn’t like the modern decor. Neither did the NY Times. I obviously don’t have a good eye for these things.
TomVDB··on FTC sues to block Nvidia-Arm merger
Apple has a perpetual ARM architecture license. Nvidia wouldn’t be able to force chips on Apple at all.
TomVDB··on Zillow lost money because they weren't willing to lose money
But what if iBuyer calls the Wallstreet Chronicle and tells them that Blue Horseshoe is buying 742 Evergreen Terrace?
TomVDB··on Impossible Foods brings total funding to $2B with new $500M raise
$500M should be sufficient to buy out the little guy who registered the Impossible trademark way before Impossible Foods existed as a company.

TomVDB··on Intel Software Defined Silicon: additional CPU features after license activation
Similarly, if my aunt had wheels, she’d be a bike.

I don’t see the point in discussing lala land hypotheticals.

TomVDB··on Intel Software Defined Silicon: additional CPU features after license activation
Your claim about running Vmare into the ground deserves a bit more explanation.
TomVDB··on Intel Software Defined Silicon: additional CPU features after license activation
Apply this to software, and everybody will be forced to pay the Office Pro price when they only need Office Home features.

For a certain price, you can buy an Intel CPU with certain known features. For a higher price, you get more features.

This is a concept that’s used in many product classes. The fact that it’s also done for HW is just an irrelevant detail.

TomVDB··on I built a $5k Raspberry Pi server (yes, it's ridiculous)
I can’t stand the dumb faces either. And yet… I catch myself being more likely to click on them when it has a face on it. It’s the weirdest thing.
TomVDB··on Tesla displaces Mercedes-Benz as third-most-popular luxury brand in U.S.
Nobody claimed that future outlook isn’t part of the analysis.
TomVDB··on Tesla displaces Mercedes-Benz as third-most-popular luxury brand in U.S.
That's one of those classic disingenuous gotcha comments.

The fact that there's a pretty common way to value public companies doesn't mean that you can make a fortune with it, because it sweeps aside the importance of time.

Have you never heard of Keynes' classic "The markets can remain irrational longer than you can remain solvent" ?

TomVDB··on How badly is cryptocurrency worsening the chip shortage?
It won't do well.

Compare that 50 GB/s of the M1 Max to 760 GB/s of an RTX 3080. Then check prices. Even after ridiculous scalping markups, the RTX 3080 will still be cheaper.

TomVDB··on How badly is cryptocurrency worsening the chip shortage?
Ethereum mining performance relies on memory bandwidth. Designing a GDDR6 or GDDR6X memory controller is hard.
TomVDB··on PlayDate Fulfillment Delayed
You’re exactly right.

Somebody at a major chip company told me that they went looking for, and found, new customers after the automotive customers canceled their orders.

So not only did the car companies ordered more than before after they realized that demand was not dropping, even if demand for them had returned to what it used to be, the total demand from other customers is now higher too.

TomVDB··on Richard “Lowtax” Kyanka, creator of Somethingawful, has died
This is not a memorial thread. And the fact that he shot himself a day after being judged a domestic abuser adds a lot of relevant context that readers on this forum deserve to know.
TomVDB··on Memory leaks are crippling my M1 MacBook Pro
Who am I to deny somebody the opportunity to feel superior? It’s a form of community service.
TomVDB··on Memory leaks are crippling my M1 MacBook Pro
Same here. I get ridiculous uptimes on mine. (And, yes, I defer SW updates…)
TomVDB··on Memory leaks are crippling my M1 MacBook Pro
Find me one laptop with a trackpad that works as well as a MacBook and we can talk.

I use a MacBook trackpad to make diagrams, for 3D modeling using Blender and FreeCAD, to draw schematics and route PCBs with KiCAD, and whatever else you’d otherwise do with a mouse, and it just doesn’t get in the way.

Over the years, I’ve been forced to use work supplied top-end Thinkpads, HP, and Dell laptops and none come even close to even the trackpad of my long retired, lowly 2009 MacBook Air 11”.

I don’t really care whether I use macOS, Linux or Windows: they all run the same applications. I also don’t care about the price of a laptop: what does it matter that a tool that I use day in day out for years costs $1000 more?

I care that it’s usable.

MacBooks are usable for things I use them for. The other laptops are not.
