steffan··on Firefox's JIT is getting significantly faster
This is pretty mature technology, and like most mature technologies, there aren't going to be a lot of 50% improvements any more.

Look at CPUs or the Internal Combustion Engine. After 120+ years, it still improves, but you're looking at single-digit percentage points if that.

I'm not aware of a lot of things that could magically improve browser performance, but if you do, you have a great opportunity for a unicorn startup.

steffan··on RTX3080 TensorFlow and NAMD Performance on Linux
I have a 32" 4K monitor and the text quality is noticeably worse than on my Macbook Pro w/ Retina display and my iPad Pro. The dpi on the UP3218K is actually higher than my iPad (280 vs 264 iirc). That will likely be my next monitor unless another manufacturer introduces a 30-32" 8K monitor in the next few months.

steffan··on iOS 14 is available today
I've gone back and forth. I don't entirely regret running Big Sur, but it really doesn't offer any advantages to me. It's seemed more or less stable although I've had intermittent issues with Facetime not connecting to older devices.

I've become more annoyed trying to develop on it though, and outside of iOS, I do my development mainly on Linux now.

steffan··on iOS 14 is available today
I've been using the Developer Betas since the first announcement and have had only a handful of minor issues (like my Bank erroneously thinking my device was jailbroken).

I think it's probably one of the more stable iOS releases I've seen.

steffan··on Birds 'falling out of the sky' in mass die-off in south-western US
It's not cavalier as much as it is factual. Of course I would lament the loss of our entire species, but the _planet_ will go on just fine without us. We (humans) are hardly the worst thing to happen to life on the planet. If we're incapable of being good stewards of it, really we're only hastening our own demise.

> but will not pursue the high-end market mostly because of their limited TSMC slots

Your second assertion that they can make more money from a CPU wafer than a GPU is probably correct, but assuming they don't abandon the GPU market entirely, they will still be using fab capacity to produce GPUs.

If they're using limited slots for GPUs anyway, doesn't it make sense to focus on the high-end high-margin parts first?

steffan··on Is macOS Becoming Unmaintainable?
Maybe a better analogy is: You have a problem with your living room light dimmer not working. The solution is to move all of your furniture out of your house, or being generous, just the living room, and then moving it back. Would you consider that reasonable?

Assuming you have a backup, then lets say some movers come out (for free) and do the moving. That's not inconvenient, right? After all, you don't have to do any of the moving. Just wait an hour or so and the movers will move everything back and quietly disappear.

steffan··on Modeling a Wealth Tax
This is a strawman argument, but the logic actually does hold: If the original premise is true, "taxing the poor to give to the rich" would accelerate economic growth.

The problem is of diminishing returns - it would have a disproportionate negative effect on the poor and a minimal impact on accelerating growth, so it would be considered one of the most inefficient ways to achieve the latter.

steffan··on Stanford cancels plans to bring half of undergrads back to campus
It seems like an easy solution to this is to have a 'trade academy' or a coalition of trade schools that allow / require you to do a rotation in each of the related trade specialties, i.e., if building / construction related, you spend a week / month / quarter learning about plumbing, electrical, framing, mechanical, landscape, etc. This would both promote understanding of related fields and give people an exposure to a variety of potential interests.

This is not unlike the required courses that predominate pre-major studies at a traditional university (in the U.S., at least)

steffan··on Uber CEO says its service will probably shut down temporarily in California
Yet Uber was able to attract people who voluntarily chose to participate in their business model. There must have been something compelling about it.

The simplest explanation is that for whatever reason, those better-paying retail or food service jobs were not an option.

steffan··on I tried starting a manufacturing unit in India
One thing to note to, is that any American citizen would be unable to set up manufacturing this way because it is explicitly illegal for U.S. citizens to pay bribes to foreign governments. [Foreign Corrupt Practices Act - FCPA]

(Although given this account from presumably an Indian citizen, I can't imagine in any way recommending a non-local attempting this)

steffan··on Atlassian tells employees they can work from home forever
There are a number of blue-collar jobs that don't require close indoor proximity. That's almost the differentiating factor. A landscaper, welder, framer, forester aren't sitting in conference rooms breathing each other's exhalations for 8 hours a day.

And since most of those jobs aren't usually salaried, I think they'd all welcome being able to go to work and continue to earn.

steffan··on 40M Americans are at risk of eviction without a stimulus bill
That's a simplistic view that doesn't take into account property prices; not every landlord has owned property since the beginning of time, taking advantage of price increases.

Imagine a retired teacher who decides to rent out a garage apartment to supplement her pension - is she taking advantage of 'inflated rents' if the rent amount barely covers a proportional amount of the mortgage?

Additionally, landlords have to pay 'inflated property taxes', 'inflated utilities', and 'inflated garbage service' - these aren't discretionary costs for a property owner unless you advocate letting people stay in their apartments, but without landlord contributions to water, heat, cooling, garbage.

steffan··on Stingrays and Dirtboxes: how cops can secretly track your phone
The measure that describes what you state would be the median, which is defined as the point at which there are as many values above as below.

Averages will skew with large outliers on either side. E.g. if Bezos and I are alone in a room together, the average person in that room has $95B dollars. (Granted, in an n=2 situation, the median isn't meaningful either)

steffan··on Data isn't just being collected from your phone, it's being used to score you
> If I put a tracking device in my car today my rates would go up because I accelerate quickly and brake hard when conditions allow. That is not right.

If statistically other drivers who do that are more likely to, on average, result in a loss for the insurer, they are right to raise your rates. "Past Performance is no guarantee of future results"

With enough data, maybe it would support your assertion that you are, in fact, a very safe driver, by realizing that you only drive fast at certain times, in certain locations that are statistically lower risk.

steffan··on Nvidia is reportedly in ‘advanced talks’ to buy ARM for more than $32B
So in that case they really need nothing from ARM at this point
steffan··on Nvidia is reportedly in ‘advanced talks’ to buy ARM for more than $32B
Apple typically has forward-looking supply chain contracts. I imagine ARM is under contract for the licensing for long enough that Apple will build out their own design team.

Already, TSMC is the manufacturer for the cores, so Apple really doesn't have too much of a dependency on ARM in the short term.

I think what we'll see over the next 3-5 years is a divergence from the ARM-licensed design to an in-house-designed architecture: "Apple Silicon II"

steffan··on Unauthorized Bread: Jailbreaking IoT toasters
That's a logical conclusion, but many printers outright refuse to operate if any of the cartridges are out, regardless of whether the print job requires that particular color.

I'm sure many people would happily shift from printing all black, to all cyan, then all magenta (yellow probably isn't practical) in an attempt to get maximal utility out of their color cartridge otherwise.

I think it's a logical fallacy to assume you can "observe all events" in any non-trivial system, particularly where there are humans on the edges.
steffan··on Ask HN: No-FAANG-like-Perks, is it worth it?
Stay at your startup for now. You presumably make enough money to buy your own MacBook if you care that much. Ultimately it doesn't matter, it's just hardware.

Focus on the advantages you have in your situation - likely you'll be able to work on a broader part of the business than them and be able to leverage that into a more senior position elsewhere later.

Obviously (or not) you need to evaluate your progress over time. This early in your career it may not be advantageous to stay at one company too long, especially in a fast-paced environment as I understand Bangalore to be.

Re: The psychology of it, over time you'll realize that the perks, while nice, don't actually cost that much. Free snacks at work? Laundry service? Do the math yourself to understand the approximate cost, which will help you value them and help you realize that you're overly concerned about minimal things. Trying to keep up with your friends is just a trap that will make you unhappy.

tl;dr - You have plenty of time to join an MNC later. Learn what you can from your current startup.
