FlyingAvatar··on Working at Apple (2011)
All pretty much any company will say about you is the dates you worked and the title you had. They’re not going answer anything beyond that by policy. I would also say this happens pretty rarely.
FlyingAvatar··on Tesla Starts Full Self-Driving Beta Rollout
So you're going to hold off riding in vehicles with human drivers until they get augmented with LIDAR as well?

To be clear, I am not saying don't use LIDAR. I was calling out OP's statement that they would feel unsafe in a car without LIDAR since it was unable to detect an unsafe condition that they detected themselves without LIDAR.

FlyingAvatar··on Tesla Starts Full Self-Driving Beta Rollout
Not trying to troll, but your two 'cameras' were able to identify it without LIDAR, why shouldn't two or more of Tesla's / name your manufacturer?
FlyingAvatar··on Why Birds Can Fly over Mount Everest
Cool, I was actually wondering about that.

If you get it hot enough, nitrogen can be oxidized. There is plenty of fuel in that sense.
FlyingAvatar··on Apple rejects Hey for second time, threatens removal from App Store
From the Twitter thread, it seems pretty clear they are trying to comply, similar to other services.

Can you clarify where they are not?

FlyingAvatar··on SpaceX faces high bar at FCC in bid for rural-broadband funding
If conventional geosynchronous satellite internet can achieve real world latencies between 600ms and 1200ms, can you describe a scenario where having a hop time that is 60x faster could not manage to improve this by a factor of 12x?
FlyingAvatar··on SpaceX faces high bar at FCC in bid for rural-broadband funding
This is literally what happens all the time for all Internet users though wires and fiber on ground-based internet at similar or worse single-hop latencies.

The number of domains is irrelevant since most of those requests would be asynchronous. What matters is the number of hops that the traffic needs to take and the latency for each hop.

1.9ms times any reasonable number of hops would still produce a sub-100ms latency which is the FCC sites as their requirement, and would be a perfectly serviceable latency for nearly all Internet use (and is around what most users experience now).

It is unclear why the FCC would reference "the laws of physics" as a barrier for StarLink achieving this, as it is unclear how they would be causing any problems.

FlyingAvatar··on Working Group Last Call: QUIC protocol drafts
I see UDP as superior in general, and don't see a good reason to use SCTP at this point for any real use case.

IMO, it's a "good thing" for applications (or types of application) to have control over the Transmission Layer since the characteristics that each type of application might desire is different. Want your app to use raw UDP sockets? Easy. Want to use QUIC? Use a QUIC library. HTTP/3? Use and HTTP/3 library.

If it all used SCTP, you are locked in to its feature set and are likely to end up with new problems similar to what we see with TCP.

I could possibly UDP/QUIC taking over TCP in a long, long while, but SCTP is not likely to ever be usefully supported because there isn't a compelling reason to do it.

FlyingAvatar··on Apple Plans to Announce Move to Its Own Mac Chips at WWDC
What segment do you envision preferring keyboards with keys that randomly fail?

I've had 3 Macs with these keyboards (should have been two, but one died completely and had to be replaced), all of them had this issue to varying degrees. This was not uncommon for the other Mac users at my workplace.

Even if fiasco is an overstatement, the initial denial of the issue I think is the major source of it becoming a media issue.

FlyingAvatar··on Take care editing bash scripts (2019)
This advice is sensible if making the assumption that the script is for a production purpose.

If you're writing a shell script for some mundane task on your personal machine, knowing the possible effects of editing a running script is useful knowledge, especially when something might behave in a non-intuitive way.

It’s upon purchase, not yearly. Annual property tax varies by town, but there may be benefits to not being a resident in this sense. Many towns charge an higher property tax on housing for non-residents for this reason.
FlyingAvatar··on Ask HN: cloud data storage cheaper than AWS S3?
The risk profile of storing something in S3, where your data is stored in at least three different Availability Zones is completely different than a Managed Server or VPS where, if you so chose, it might be stored without any redundancy at all.
FlyingAvatar··on Neural networks as non-leaky mathematical abstraction
This entire concept seems backwards to me.

The reasoning for author's premise that sigma summation and integrals are leaky abstractions is unclear.

The two are their own independent abstractions; while perhaps complicated to fully understand, they will work exactly as designed and, provably so, from a logical standpoint. If they were leaky, they would display some kind of shortcoming that didn't allow them to convey parts of the core idea they were created to represent.

On the other hand, an NN implementation of any sufficiently complex concept is almost guaranteed to be leaky as it is too complicated to be provably correct, and will have too great a test surface to verify exhaustively. There are likely to exist edge cases where the NN fails outright that will be never discovered until used in a specific scenario. That seems leaky.

Can someone set me straight on what the author was trying to convey?

It's Rosie the Riveter. It's dressed up like her, apparently.

FlyingAvatar··on Aviation Is on a Low-Carbon Flight Path
Judging by the amount of volume of a rocket or ICBM that is consumed by its fuel, I would have to venture that it's nearly impossible that it's cleaner.

FlyingAvatar··on Tesla’s new Solar Roof costs less than a new roof plus solar panels
Exactly how is that out of the reach of anyone but the wealthy?

Amortized over 30 years, it's barely over $110 per month and for most homes would bring the electric bill to near zero.

FlyingAvatar··on AWS Customers Rack Up Hefty Bills for Moving Data
Reading this, I immediately thought: the cost has to go way down with 200TB of volume.

It goes down, but only to $14,131.11!

Nice find. I will file this away if I ever need to do a full remote recovery.

FlyingAvatar··on IRS sends warning letters to more than 10k cryptocurrency holders
And easily mitigated by converting the amount you owe in tax at the time your are paid. I don't see how this would be different than getting paid in any other currency.

The problem in your scenario is not really to do with tax, it's that one has effectively expended $10,000 worth of effort for $100.

If someone was worried about this, they shouldn't be accepting BTC as payment, or they should convert it to fiat currency immediately upon receipt.

FlyingAvatar··on Ask HN: What are some fun projects to try out on a spare Linux file server?
Definitely something to consider, but unless you're running some old big iron hardware, 300 watts would be a very high average for a mostly idle server.

I have a nearly 10 year old HP Microserver with 4 SATA disks and the average usage is less than 50 watts.

FlyingAvatar··on Humans have made 8.3bn tons of plastic since 1950
I think he was referring specifically to entropy in his reference to thermodynamics. Once we extract the source materials from the earth, turn them into plastics and distribute them, there is no cheap way to undo it.
FlyingAvatar··on Training a single AI can emit as much carbon as five cars in their lifetimes
"In particular, they found that a tuning process known as neural architecture search, which tries to optimize a model by incrementally tweaking a neural network’s design through exhaustive trial and error, had extraordinarily high associated costs for little performance benefit."

This is specifically the ONE instance that uses five cars worth of CO2. The next highest example used 435x less CO2. Click-bait titles like this incite unnecessary ire.

If you're spending $1,000,000+ on cloud compute costs, you're (a) hopefully very aware that this is burning a lot of CPU/GPU cycles, (b) very unlikely to try it again if the gains are minimal as the paper states.

FlyingAvatar··on Switch from Chrome to Firefox
I think you mean you're disappointed with Firefox on macOS?

If so, my experience has been the same, though I have been sticking with it for now.

I often find I have to close out Firefox and restore my session to stop it from churning so hard my fans spin. This is particularly true after it has been running for a while or after resuming from suspend.

FlyingAvatar··on MitM'ing my STB (2016)
Back in 2005 or 2006, I had purchased a cable-ready QAM PCI Tuner card. When I scanned channels, I saw a number of very high numbered channels that all appeared empty of content.

One day, I was flipping through the channels, I hit one of the high number channels, a relatively newly released movie was playing on it. I started watching it for a bit and the video paused for a second and then it started rewinding.

It took me a few seconds to realize that the Video on Demand service was being transmitted in the clear on these high number channels and the people's STBs were programmed not to see them. With the PCI card though, I could see any VoD being played on my local "circuit".

FlyingAvatar··on Ask HN: What would you like to say to your fellow HN readers?
I find that I am very good at stereotyping.

When I stereotype people who I disagree with, it's very easy to engage with them in a way which will induce them to reciprocally stereotype me.

In this mode, it's possible for us both to speak with each listener only hearing the words that reinforces their own stereotype.

I find this also happens in reverse when engaging people who I agree with, making me feel better about my preconceived notions but not really challenging my views.

My task has been to talk with more people who I disagree with and listen to them. If I can't convince them of my view, that's ok. If they can't convince me of their's, that's ok.

So far, this process has been more frustrating in the moment, especially at first, but has generally left me feeling better about humanity.
