ericbarrett··on AI and satellite imagery reveals expanding footprint of human activity at sea
They aren't visible on these sites, first thing I checked. Maybe they've requested delisting but I think they're just not broadcasting—specifically to avoid consequences of their reckless flying.
ericbarrett··on AI and satellite imagery reveals expanding footprint of human activity at sea
There's some yahoo who buzzes my house twice a week in a Cessna (coming and going). He's often under 500' AGL. No ADS-B and haven't gotten a tail number yet. I think it should be illegal to not have it enabled, for exactly this kind of thing.

In fact I wonder if it's even a licensed pilot—William Bushling apparently flew for 20 years without a current FAA license and also didn't use ADS-B; when he finally lost the dice game it took them days to find the wreckage: https://youtu.be/69NvK6YbNtg

ericbarrett··on The drive stats of Backblaze storage pods
My sense is that storage server prices have had to come down to compete with both cloud (like S3 archival tiers) and roll-your-own solutions. The former are relatively recent and the latter have become more feasible as companies—Backblaze among them—have open sourced well-engineered designs. Storage server margin used to be insane, over 80% after COGS back in the 00s and only slightly less last decade, and there's still room to compete.
ericbarrett··on AI generated security reports about curl
He makes a great point, but I think writing in an authentic, un-augmented voice will very quickly become the only way to be noticed. Which is a shame for otherwise benign uses of the tool.
ericbarrett··on 4B If Statements
GNU yes will actually repeat any string—the default is of course "y". So it's very handy for scripting, and not really as single-purpose as you'd think.
ericbarrett··on Generation Junk
Same thing a $100 microwave does, just really stylishly: https://www.subzero-wolf.com/wolf/microwave-ovens/30-inch-m-...

(Ok, fair, that's only $2,500)

ericbarrett··on Generation Junk
They are probably all made with the same guts from one or two manufacturers. Same with microwaves, nearly every model from $100 to $5000 is made by Midea. (Source: Wirecutter)
ericbarrett··on Generation Junk
The comparison I'd make is not to cars from the 20th century, but the early 21st, about the last your grandfather experienced. There's a vast difference in the quality of a car from 2005 or 2010 and the equivalent from 2023, and it's not favorable to the latter.
ericbarrett··on Ask HN: Why is my web server being attacked?
While I agree with other commenters that 100/hour doesn't rise to the level of "attack," I'm also curious, because with a forged peer address these are certainly not probes—the true sender would not get a response either way. Unless, that is, the spoofed IPs are also controlled by the attacker. I wonder if you'd find any patterns (net range, ASN, geographical, residential, etc.) in an analysis.

It could also be that your server—no doubt along with millions of others—is simply being used as a bouncer to shield the origin of a DDoS attack. Typically attackers want "amplification" (send a tiny packet with a spoofed source address, get a large response) but if their pipe is big enough they may be content with a level of indirection.

ericbarrett··on Colorado wolf reintroduction to move forward
> How come there isn’t a predator collar that releases pepper spray when wolves go in for the throat kill?

The wolf collar was invented for this and dates back to Ancient Greece:

https://en.m.wikipedia.org/wiki/Wolf_collar

Typically it was/is fitted to guard dogs who would then fight the wolves.

ericbarrett··on A data corruption bug in OpenZFS?
As a grizzled old storage admin who somehow made a career out of database backups, I wholeheartedly agree with all of this. Especially having someone else do a test restore. They don't have to be junior, just not intimately familiar with the systems involved.
ericbarrett··on Sudo without a setuid binary or SSH over a Unix socket
Do the workloads need to share their state simultaneously? If not then you probably want SAN (exported block devices) instead of NAS (exported file systems).
ericbarrett··on Possible to detect an industrial civilization in geological record? (2018)
You’re right about satellites but I think you’re underestimating how long a monolith could last on the Moon. For something big and built to last, it could be many many millions of years https://bigthink.com/starts-with-a-bang/astronaut-footprints...
ericbarrett··on Possible to detect an industrial civilization in geological record? (2018)
The Lunar Orbiter Laser Altimeter has mapped the lunar surface to, best as I can tell from a quick search, about 1m resolution. So I think a reasonably sized stele or 2001-style monolith would probably have been discoverable at our current tech level.
ericbarrett··on Blindsight by Peter Watts (full novel)
I found the PDF much more readable than the epub. The fonts or something. Finished it on my iPad using the stock PDF viewer, it’s pretty good in iOS (except it forgets your page sometimes).
ericbarrett··on Tacit Knowledge Is Dangerous
OP mentioned meeting notes (like otter.ai) and other ephemera. I think that really changes the risk profile.
ericbarrett··on Tacit Knowledge Is Dangerous
I think being able to steal a language model that can instruct you on things like the notes of every meeting, employee relationships, back-channel drama, security discussions, etc. and how these things relate to corporate and technical assets, all contained in a single artifact/tarball, really ups the ante for what kind of "security hardening" you'd need for this.

Even exfiltration of API access for a few well-prompted queries could be really bad.

ericbarrett··on Tacit Knowledge Is Dangerous
Such an oracle would be a devastating thing to lose to industrial espionage.
ericbarrett··on Check Fraud Is Rising and the Thieves Are Winning
What's stopping banks from increasing this charge to $10 or $50 or a percentage, on top of the Fed charge? Because if they can, I'm sure they will.
ericbarrett··on Air traffic controllers pushed to the brink
My internship in the mid-1990s was with a professor studying VR systems for ATC for low-visibility operation. At the speed this field changes (or doesn't), I doubt I'll see it in my lifetime.
ericbarrett··on A Critique on “A Critique on the OpenPGP Updates”
The lwn.net article linked in this post has an excellent, seemingly neutral summary of the issue that casts a lot of light on TFA; I highly recommend anybody interested in the OpenPGP schism read this.
ericbarrett··on Which Movies Are the Most Polarizing? A Statistical Analysis
I laugh so hard at the opening of 2001. Not the monkeys dancing around the monolith; rather, the opening title: the orchestration of Also sprach Zarathustra crescendos on "Stanley Kubrick." What an arrogant monument to himself! One wonders if he took it so seriously or if there was a wink and nod behind it.

I do love the movie though. It drags on, and it's psychedelic in a way that doesn't really translate to modern, sober viewing; yet the special effects and researched realism larded into it would take Hollywood many more decades to embrace. And HAL is still a character for modern times.

ericbarrett··on Thermoelectric heating stands at the brink of commercialization
Residential pellet stoves sound great but in practice they are not reliable (moving mechanical parts that operate at high temps, electronics poorly shielded from said temps—the manufacturers are pretty shady in my experience), and the cost of fuel varies quite a bit and can be very high. Compare to a wood stove that needs no electricity and can burn just about any combustible solid. Modern wood stoves are pretty efficient, too.
ericbarrett··on Who makes the most reliable new cars?
My 2019 vehicle's manual explicitly says not to do this, and that if the battery fully discharges you should make a follow-up service appointment to frobnicate the computers. I miss older cars.
ericbarrett··on My $500M Mars rover mistake
Everybody replying to you that this is fragile is missing the point. This kind of code isn't the first line of defense—it's the last.
ericbarrett··on An Invasive Tick That Can Clone Itself Is Spreading Across the U.S.
> Opossums

Sadly, opossums eating ticks is likely a myth, or at least incorrect extrapolation from lab captivity stress: https://www.sciencedirect.com/science/article/abs/pii/S18779...

ericbarrett··on Developer account removed by Apple
In the time it took you to compose this reply, Apple made more money (in profit, not revenue) than the amount in TFA. Your cynicism borders on conspiracy theory!
ericbarrett··on Developer account removed by Apple
Apple's revenue is $12,000 per second.
ericbarrett··on Apostrophe Protection Society
I don't add the extra s, nor do I speak it aloud. Also American (western).
ericbarrett··on The Mushrooms That Ate Luke Perry
This is a great essay on “mushroom suits” and could be an HN submission on its own. Thanks for posting!
