Flighty is very pretty, but I’m not giving up FlightAware anytime soon.

I travel a lot, and frequently encounter flight delays. It’s mind boggling difficult to find out where my plane is when it’s delayed via Flighty. This and a few other things, FlightAware gets right.

I feel like Flighty is for rare leisure traveler and FlightAware is for weekly business and/or pilot traveler.

I’ve honestly had better luck with iOS built in flight tracker than Flighty itself.


Flighty is in a weird place because I'm a rare/leisure traveller and wow Flighty nowhere near reasonably priced for that market.

I used it in free mode when I was on iOS, but it would be ~£10 per trip for something that would improve my life less than a coffee at the airport.

In my opinion they need to aggressively cut costly features (like weather data), and if they have different international data feeds, perhaps do region locked pricing. I don't fly to the US much, so let me buy a Europe and Asia subscription and skip the US costs. Or vice-versa. It would have needed to be ~£10 a year at most.


What does it actually do? People seem to get very excited about it but my flight status is always either “on the plane” or “not on the plane”

The promise is that it informs you quickly about flight delays, flight cancellations and gate changes. In my limited experience, it didn’t work satisfactorily for a flight delay of a few hours. It could not provide any reliable updates.

It’s a nice app and service, but I wouldn’t trust all those reviews that are like “I knew before the aircraft pilot knew”. It has its own limitations.


I don’t see any value in knowing before the pilot knows. I’ve mostly flown American the past few years and with their app I get updates about delays and gate changes on my phone just fine. I suppose there might be some advantage to getting the notification a bit earlier, but I doubt that they can reliably give information faster than the airline itself.

I think I figured it out - if you can figure out a cancellation before everyone else you can get to the counter and get on another flight before everyone.

I've had once cancellation in my life so I see why the need hasn't presented itself very loudly.


Yeah, the most notable "use", not necessarily "value", is when the airline is still prevaricating over the delay, you're approaching boarding time and you can see from ADS-B that the inbound aircraft hasn't even begun initial descent.

I still don't really see the use, but maybe there are large swaths of people who stay home until they can leave at the very last minute.

I'm almost certainly going to be waiting at the airport anyway by the time the delay is confirmed.


Last year Flighty literally saved me from an overnight delay because it notified me the incoming aircraft was still on the ground at the previous airport. I was able to snag the last couple seats on a later scheduled flight which actually departed. My original flight ended up getting canceled.

Thank you! That's the use case and I see the value; I learned to compensate by never taking the "last flight out" if I could avoid it.

What do you do with that information though?

As airline crew, I stay in the lounge (employee lounge, not bar lounge) when I know I'm not going anywhere on time.

Flighty gets heavy use from US airline employees. We're frequently in the airport with a brief break before flying the next flight. Usually, this next flight will be on an aircraft that hasn't arrive to the airport yet. Most of us will find a quiet place to relax for awhile and it's really irritating to pack stuff back up and walk to the gate just to find out there's no plane.

Another scenario is you arrive to an airport and need to switch aircraft. The "turn" time might be scheduled for 45 min. It's really nice to know as you walk off the aircraft that "Hey, it's actually delayed. Now I have 2 hours." I'll go grab a bite to eat or catch up with family back home etc.

My particular airline will show you what the next inbound aircraft is and it's flight number and ETA but it's a "fetch" experience. You open the app, wait for a refresh, click like 4 times to navigate to the right page, get the tactical information. Flighty keeps it on the lock screen. Just lift your phone and it's there.

We're constantly asking our employer to emulate Flighty. Tech isn't their strong suit though.


Sounds like you identified a business opportunity for Flighty - license the functionality or just sell app access to the entire airline, at least for employees.

Nah they’ll ruin it. I’d rather Flighty charge a couple hundred bucks and maintain a comfortable business than let my employer wreck a good thing.

I’m a touring lighting designer, I fly anywhere from 20-120 times a year. Every fellow LD I know uses Flighty, any time i get delayed flighty tells me before the airline does.

I especially love that it usually tells me or warns me about a delay before I leave the lounge, so i get to spend some more time relaxing. That and of course the amazing data in your flighty passport!


This looks like you signed up for hacker news to post ads on this ad.

I fly around 6x/yr but I still found it useful enough to get the lifetime plan. I suppose if I only flew once per year I wouldn't have gotten it, but I don't mind paying ~$10/flight (probably even lower by now, and who knows what it will drop to by the time Flighty stops working, hopefully more like ~$1/flight). A typical trip might cost in the range of ~thousands of dollars so $10 to reduce my stress levels when there is a delay is worth it in my book.

For example... if there's a delay and so because you found out sooner you can stay home an extra hour instead of sitting at the airport I would pay $10 for that.


Flighty routinely tells me about cancelled flights before any other app or the airline itself.

FlightAware and Flighty are usually within seconds of each other and always ahead of the airlines.

(except United)

I agree, I find that the "MiseryMap" from flightaware is less "pretty" but much more informationally dense. https://www.flightaware.com/miserymap/

I’m genuinely inspired by your journey.

One question for clarity: why don’t you see an opportunity to sell AI or other technology into this space again? Is it just because incumbents already have it locked up and it’s cheap?

The reason I ask is that this feels like one of those moments in history similar to mobile. PlanGrid succeeded because tradespeople suddenly had iPhones and iPads in the field, which made it possible to digitize blueprints and collaborate in real time.

Put differently, what could be the new “PlanGrid” for your industry - that AI makes possible now, the way mobile once did for construction?


Pest control is about 60% consolidated, and I don't want to pick the fight of convincing the top 5-6 to buy more SaaS or AI. Realistically they're looking to Salesforce for leadership there.

I see today's consolidation as fragile though, and it's not locked in forever. I'm better at building a competitor where I have full influence of the customer and worker experience, and I have the patience to see it through.

Part of shaping my thinking here is 1) knowing what I'm good at, much better than I did before, and 2) in my previous company we built a heavy equipment telematics platform which was used on about 1/3 of the UK's infrastructure projects. JCB (an equipment OEM with their own bad version of what we were doing) threw the kitchen sink at field sales and account management, and they had reach into all the sites across the country. It was an eye opener and good lesson about go to market for enterprise sales in traditional industries.


For those, like me, who find the prompt itself of interest …

I wonder what was in that solutions file they provided. According to the prompt it’s a solution template but I want to know the contents.

Another thing I want to know is how the user keeps updating the LLM with the token usage. I didn’t know they could process additional context midtask like that.


Re: transition to micro services (from monolith).

I’m surprised a network so sensitive to latency (as are payment networks), was able to achieve their latency SLAs with micro services.

Maybe Amex being a closed-loop network helps with latency?


Every major high-throughput database now runs as microservices, not sure why people still act like things just grind to a halt when the network is involved.

High-throughput is not the same thing as low latency. In fact, they're often at odds with each other

Since when were payment networks latency sensitive? It’s usually 2 or more seconds to even get a payment up on the card terminal from the merchant POST system, then 2-5 seconds more from card presentation to getting approval back.

> Since when were payment networks latency sensitive?

Since the advent of e-commerce, POS-networking and fraud detection systems in 1990's-2000's.

User-facing and authorisation path are highly latency sensitive. It includes tap-to-pay, online checkout, issuer authorisation, fraud decisioning, and instant payment confirmation – even moreso for EFT payments.

> […] 2-5 seconds more from card presentation to getting approval back.

This is the mid-1990's level QoS when smaller merchants connected the acquirer bank via a modem connection, and larger ones via ISDN.

Today, payments are nearly instant in most cases, with longer than one-second card payment flows falling into the exceptions territory or inadequate condition of the payment infrastructure.


I’m fairly certain that’s a POS issue, not the payment network.

I’ve heard anecdotally that it’s < 140 ms for payment networks.

Anyone, please correct me if you know better.


It's definitely not 140ms round-trip. Issuer processors typically have a ~2.5s window for approval.

In practice, the POS sends a message to the acquirer processor -> hits the network -> is sent to the issuer processor, and back again.

https://medium.com/wharton-fintech/the-anatomy-of-the-swipe-...


yeah, if the card is an EMV chip card, and might also have a SVA so everything is handled between the terminal and card, it can be blazingly fast.

In EU they use of offline PIN was used massively before PSD2 and contactless, that made the terminal request during the time it took for validating the transaction online, and basically as soon as the PIN was ok'ed by the card that confirmed the transaction. That gave a perception of speed.

Now it's basically online PIN mostly or contactless, but that means you perceive a "wait for an ok", that you had before but was masked by the PIN capture and check on device/card.

So we went a bit backwards for cards, but wallets like ApplePay went a bit forward. You win some you lose some I guess


140ms is still a ton of time to do a simple transaction

It's not simple though. In that 140ms the network is checking fraud rules, validating the card, checking available credit, applying rewards logic, and routing across multiple parties. The actual subtract-one-number-from-another takes microseconds. The rest is trust verification across organizational boundaries — which is the hard part of any payment system.

At best it’s checking available credit. All the other stuff is done after the fact. The idea that any banking transaction involves “subtracting one number from another” is so wrong it’s barely worth engaging with.

You speak so confidently, yet it appears you’ve never gotten a text asking you to approve or deny a charge that you are performing.

Some (rewards processing) is probably done later, but the fraud check definitely isn’t.

>Since when were payment networks latency sensitive?

Apple Pay is extremely fast from my experience (at least the web version). There is a high percentage of market loss if payments take long or fail. Im sure there must be a graph for where it plateaus with diminishing returns when it comes to speed but faster payments definitely help with sales.


> Maybe Amex being a closed-loop network helps with latency?

Yes, this is a huge deal. VisaNet and friends have to wait on the actual bank cores in order to perform online authorization. Amex can guarantee end to end latency.


Doesn't matter if you have 500 microservices if only one or two take part in card authorization (as it should be if microservices were architected correctly).

There's ton of logic on non-critical path that can be extracted to other microservices and called asynchronously - settlements, refunds, rewards, all management and reporting functionalities - to name just a few.


Let’s restate this another way:

“ In an interview with {COMPANY} I was literally told that … {COMPANY-OWNER} can call us and demand anything at anytime. “

Doesn’t sound so crazy when Elon name is removed from it.

Note: I’m no Elon fan, but do think sometimes HN overreacts when his name is mentioned.


If you're designing a car, then the CEO/Founder might want the ability to add falcon wings to it at any point, and that's pretty reasonable. If you're designing a trustworthy encyclopedia, knowing that the CEO/Founder might wish to alter arbitrary facts to his whim is really not very reasonable. Is it his company? Sure. Do you want to make low-quality information artifacts? That's a judgement call.

What? I work for a different frontier lab now, and it absolutely would be ridiculous if they told me the same thing. Luckily they haven't.

What products have you worked on where this would be deemed normal?


Sounds pretty crazy to me, bud. I keep landing on 'servitude with extra steps'. Owner should have better things to do/people to bother, I should have space. Boundaries, etc. Yeah yeah, I'll never make a bazillion dollars. I'll know freedom.

Even an executive assistant, which I would never apply for, has off hours.


Anthropic, can I please signup without the need to share my mobile number.

Tangentially related: I haven’t seen DragonflyBSD talked about on HN in a long while but wasn’t it a split from FreeBSD to be built entirely around message passing as the core construct.

And with the tiny team working on it, it has remarkable performance.

I didn't realize Moltbook and OpenClaw - were created by different people.


I thought Moltbook is what OpenClaw was called before it got renamed


You're thinking Moltbot


> This is the latest video to have emerged from the extraordinary incident earlier this week in which a Kuwaiti Air Force F/A-18 Hornet was responsible for shooting down three U.S. Air Force F-15E Strike Eagles.

Why is the US using such dated planes?


They're not really the same planes, they've been continually upgraded over time. For another example, The B-52 strategic bomber is being used right now and but it was also operational during the Korean war. However, the B-52s flying today are very different than the ones flying back then. Another way to think about it is a computer with an old case but upgraded mb, cpu, and ram.


F-15E Strike Eagles have advanced avionics and can and continue to use advanced missiles. They can serve in multiple roles including target identification, aerial combat, and of course air-to-air interception and ground attack roles.

Same thing with the F-18.

Eventually of course all of these weapons platforms will be phased out, but for the time being they are still extremely useful, and even more so after the more advanced aircraft and other attack vectors have taken out or limited air defense capabilities or the ability for enemy aircraft to intercept these aircraft. Not that they can't handle their own, anyway.


Much of the F-15E fleet is still in relatively good condition. Most other airframes are even older on average. Over the past couple decades most funding went to more urgent GWOT priorities and almost everything else was under capitalized to the point where older aircraft are literally cracking and falling apart.


These aircraft are maintained pretty well. They have explicit refresh cycles where they're taken to depots and pretty much torn apart and then rebuilt. The electronics also get refreshed over time with newer components (not just newer versions of old components or refurbished components, but new electronics and computer systems). It's not like they're still frozen in time at whatever version was initially put out 50 years ago.


The F-15 family is kind of best-in-class still. It is an agile jet with a lot of weapons. As for the E variant, we tend to just run them until the airframe ages out.


The F-15E has received several service upgrades in its lifetime and has served as the base platform for most F-15 variants sold to other nations over the last decade or so. It's far from dated. They make new ones in St. Louis.


Because they still work.


Both Datapacket & OVH have the 4565p.

This proc is a hidden gem.

For most workloads it’s not just the most performant, but also the best bang-for-buck.


I don't see the 4565P at Datapacket or OVH. But that doesn't invalidate your comment.


They have the higher cache variant (4585PX - same clock speed & core count)
