JCBird1012··on Show HN: Let's Seal – Let's Encrypt for document signing, free and self-hosted
In my opinion, all of these open source/free/open document signing tools are neat on paper (and technically fulfill the goal of being able to verify a document's chain-of-custody/signature provenance) - but won't take off in any meaningful way legally because there's no entity behind them taking the responsibility for accuracy and culpability.

DocuSign/Adobe/whomever is trust anchor, it's an entity you can sue or subpoena if something goes wrong. Someone who's actually on the hook for making sure whatever's signed is accurate and truthful (outside of the reputational risk of fraud completely obliterating any trust in your platform)...

No amount of cryptographic verification substitutes for having a legal person on the other end who can be held accountable for actually verifying the document was signed accurately/process was followed.

A related project, but for birds - https://motus.org

Motus is a distrbuted network of ground stations for tracking birds and other species (like bats!) for research - they also use CTT tags for tracking (along with tags from another company called Lotek - https://www.lotek.com)

And just when I thought the DPE system couldn’t get any worse.
JCBird1012··on Enjoy CarPlay While You Still Can
CarPlay and Android Auto were engineered from the start to be as agnostic to the car's hardware as possible. Your car's stereo is really just a dumb screen (i.e. just a display and input/output interface) with the phone doing most of the rendering + a few other things (i.e. providing some car instrumentation, like fuel remaining, if the manufacturer enables it) - the hardware requirements aren't really strict from a performance standpoint (minus CarPlay Ultra, and even then, that's just a tighter integration).
JCBird1012··on Someone keeps stealing, flying, fixing and returning this man's 1958 Cessna
It depends on the airport! Some smaller airports (like Corona Municipal Airport where the story is based) - are untowered, meaning that there's no central ATC to chat with when taking off/landing - everyone announces what they're doing as they're doing it and there's a traffic pattern/flow that everyone follows to ensure there's no conflicts - it works surprisingly well.

In the US, you can get shockingly very far without having to chat with ATC.

JCBird1012··on Show HN: Stasher – Burn-after-read secrets from the CLI, no server, no trust
I'd recommend changing your tagline -

A server sure sounds like a backend to me.

JCBird1012··on Ubiquiti launches UniFi OS Server for self-hosting
It’s there - just built into the binary. ;)

but yeah that was upsetting - I was hoping they’d push them to a registry and make them… more available.

JCBird1012··on Ubiquiti launches UniFi OS Server for self-hosting
Even better - you don't even have to run Network - UniFi APs have standalone mode - https://help.ui.com/hc/en-us/articles/12594679474071-Standal...
JCBird1012··on Ubiquiti launches UniFi OS Server for self-hosting
1. This is an official Docker image/container from Ubiquiti themselves - no more relying on LinuxServer.io/jacobalberty, etc...

2. With the "UniFI OS" branding, the door is open to the possibility of being able to run Talk, Protect, Access, etc... on your own hardware in the future.

JCBird1012··on The Gen Xers Who Waited Their Turn to Be CEO Are Getting Passed Over
And don't downplay how much of a role politics can play at making those facts/performance metrics harder/easier to achieve - and some companies are excellent deluding themselves into thinking it's not the case.
JCBird1012··on Lume: The Robotic Lamp
I know the intro video is a render - but the folding of the purple sheet looks so... unnatural (to put it lightly) - like the cloth physics do exactly what is convenient for the video and don't reflect reality.
JCBird1012··on Personal aviation is about to get interesting (2023)
Don't picture them as OTA firmware updates. Picture them as OTA navigation data updates (i.e. maps, charts, waypoints, airport info, etc...) - that's much easier to pull off.

The process right now is pulling out an SD card from your Garmin/Avidyne/BendixKing whatever every 28-days or so (that's how often the FAA updates the navigation database backing these avionics), popping it into your PC, using software/webistes that could be... much better designed (to put it lightly) and then going back again. It's not exactly the hardest thing in the world, but it's not exactly a walk in the park either (especially for less-technically inclined pilots, who just let it lapse, and click out of the big expiration warnings every time they start up their planes).

JCBird1012··on Faking a JPEG
I can see what was meant with that statement. I do think compression increases Shannon entropy by virtue of it removing repeating patterns of data - Shannon entropy per byte of compressed data increases since it’s now more “random” - all the non-random patterns have been compressed out.

Total information entropy - no. The amount of information conveyed remains the same.

JCBird1012··on Panel says FAA should end mandate pilots disclose talk therapy sessions
As a pilot, yes, your conclusion is correct - it’s widely known “tribal” knowledge among most American pilots that any reporting on the FAA medical certificate application is ammunition that the FAA can then use to probe for additional information, request further medical tests/notes (which, by the way, likely have to be paid out of pocket), or outright deny the medical certificate, effectively grounding them indefinitely. Appealing that process is long, arduous, and filled with many headaches.

With that said, the application for a medical certificate is a federal form, and willingly lying/omitting information on it is a felony - the FAA has also been known to pull medical records where they can - typically for veterans receiving VA benefits (https://www.washingtonpost.com/politics/2023/08/27/faa-pilot...) - pilots don’t want to get caught in a lie, so many just outright don’t seek treatment for some conditions - particularly mental health ones.

I see this panel ruling as a positive thing because it’s one less thing pilots have to worry about when applying for a medical certificate - knowing they can see a therapist without fearing potential ramifications (because it won’t have to be reported to the FAA in the first place) is a huge step in de-stigmatizing mental health conditions in aviation.

JCBird1012··on The little SSH that sometimes couldn't (2012)
Reading this made me think “huh, where have I seen something like this before?” - an AT&T router was doing something awfully similar back in 2020 - https://news.ycombinator.com/item?id=25335936
JCBird1012··on India calls for all mobile phones to include FM radios

JCBird1012··on Emergency SOS via satellite is included for free with iPhone 14 Pro for 2 years
Carriers in the US are basically required to route 911 calls, even for devices not on their network - I wonder if that’ll include T-Mobile’s/Starlink announcement (since they’re going to be using existing 5G spectrum, I would presume so) - if I’m out in the wilderness and I experience an emergency, in theory, 911 should just work for me, piggybacking off a Starlink satellite, even if I’m a Verizon or AT&T or whatever subscriber - if that’s the case, I don’t see the need for all of these competing Emergency SOS via Satellite offerings.
JCBird1012··on FAA revokes licenses of pilots in failed Red Bull plane swap
I’d imagine the number of highly skilled stunt pilots willing to do a stunt like this drops proportionally in countries with lenient aviation authorities.
JCBird1012··on FAA revokes licenses of pilots in failed Red Bull plane swap
> Best might have been to do this stunt outside of FAA jurisdiction.

In order to do this, that would mean not using pilots with an FAA certificate, nor an American-registered aircraft.

Even if they did this over the middle of the ocean, in international waters, if even one of the two things above were used, the FAA still has jurisdiction.

JCBird1012··on Red bull is denied FAA exemption, crashes Cessna 182 anyways
More than likely it'll be a fine for Red Bull/the pilots involved - and at worst a revocation of the pilot certificates for the pilots involved for continuing ahead despite knowing that an exemption wasn't granted.
JCBird1012··on Seriously, Stop Using RSA (2019)
A backdoor in Curve25519 hasn’t really been a concern, because unlike P-256, the parameters for the curve didn’t come from NIST. Curve25519 is a djb (https://en.wikipedia.org/wiki/Daniel_J._Bernstein) special.

So unless djb was secretly working with the NSA and willing to risk his reputation to backdoor a highly scrutinized elliptic curve, the risk is low.

JCBird1012··on Launch HN: Gravitl (YC W22) – VPN Platform Based on WireGuard
One of the nice things about NetMaker (at least that I've seen), is that it supports the vanilla WireGuard iOS app, just without the mesh capabilities and other automation.

I have my iOS client set up with a egress node on Netmaker, it gave me a vanilla WireGuard config and then I passed that to my iOS device.

JCBird1012··on Half of American kids have lead in their blood, doctors say
Smaller general aviation aircraft still use 100LL gasoline (the LL stands for low lead) - and even though there’s lead-free replacement candidates (still going through regulatory approval, at least in the US), it’s been known that areas around airports with frequent GA traffic have higher levels of lead in the air, and children living near said airports may have elevated levels of lead in their blood (https://paloaltoonline.com/news/2021/08/06/new-study-finds-l...)
JCBird1012··on FCC Temporary Waiver Permits Higher Symbol Rate Data for Hurricane Ida Traffic
In a way, it’s funded by the entities that actually need to pay for an FCC license (mainly commercial ones)… AFAIK, the FCC ULS (Universal Licensing System) is a unified database of all FCC licensees, regardless of type. If paying licensees can fund the database, then tacking on Amateur licenses to it is a marginal (if not effectively zero) cost.
JCBird1012··on IPv4 pricing
That’s a good way to suddenly get those organizations to magically start using those IPs suddenly - if you threaten to take unused IP blocks away, I’m sure those orgs will somehow find a way to “use” them.
JCBird1012··on GitHub Copilot
It's funny that GitHub ships their own text editor, Atom, but the second example (under the "More than Autocomplete" header) on the Copilot website is clearly using VSCode.
JCBird1012··on I made 50k calls to explore the telephone network
To be fair, most of the original recordings (with caveats listed there) were linked at the bottom, so I presume that the author still has them around - that's hardly "throwing" them away.

I don't think the goal of using Google speech-to-text was to solely use the transcriptions for the rest of the project, but you've gotta find some way to sift through those recordings and pull out the interesting bits. I think that was the right choice providing additional context and picking out the good stuff. Imagine having to listen to ~28 hours of recordings (60 sec * 1724 answered calls) when there's a service that can easily turn those recordings into a more easily consumable format, and then you can go back and listen to the neat stuff.

JCBird1012··on WWDC21
You're right! In fact, the last iPhone to be revealed at a WWDC was the iPhone 4 in 2010.
