Also, a thread from one of the pilots: http://flightaware.com/squawks/view/1/7_days/popular/24611/BOE236_787_performing_a_787_with_a_logo#36259 http://flightaware.com/squawks/view/1/7_days/popular/24611/B... Interestingly, this required a lot of work on our side to pull this off. Since the route field on flights plans expects short input and this flight's route is dramatically longer, it caused an FAA system to split the flight arbitrarily into different legs.

> I work for FlightAware Cool! Say, are you guys still running on Apache Rivet, just out of personal curiosity?
- DavidChouinard 15y ago
  Yes, we do (we're about the only serious production site running Rivet left). Our codebase is almost entirely in Tcl (sigh). Apart from that, our core algorithms are in C and we run a pretty serious production Node.js app.
  - davidw 15y ago
    Tcl's pretty cool, and I think it could have kept going interesting places if things hadn't fallen apart in some critical ways. Especially back in the day when the competition was stuff like PHP or Java. But it's no fun to be working with something that's not headed anywhere. It's great to see someone using Rivet, though. Damon Courtney and I wrote that something like 10 years ago, with the occasional input from Karl. I wish I had half the business sense that Karl seems to, he seems to come up with a lot of good products that also make money.

      Didn't TCL not get constant-time array lookup until like version 8?
      - davidw 15y ago
        It's had "lists" (arrays) since... forever, as well as "arrays" (hash tables). Also appearing in version 8.1 (in 1999) were Unicode and good support for threads, stuff that systems like Ruby only got recently.
        joshu 15y ago
        Yes, but iirc array lookup was not constant time.
        jrockway 15y ago
        Hash lookup is constant time. The constant is merely higher than for a multiplication-and-addition-based vector lookup.

      > Tcl's pretty cool, and I think it could have kept going interesting places if things hadn't fallen apart in some critical ways. Hey David, nice to see you again :) With respect (as always) I don't get what you're talking about. You've written over the years that Tcl suffered from a marketing problem. No question. The rest of your anti(?) Tcl writings seem to make allusions to problems, but never really express what the problem _is_. I'd love to spend some with discussing this with you (email perhaps, or in quiet irc space?). When I describe Tcl, I start similarly to you (Tcl's pretty cool...) and build on that, rather than detracting from it. Tcl is _fun_ like nothing else I've played with, has a brilliant C API, is incredibly dynamic, etc., etc. Even despite the apparent lack of popularity, it's _still_ everywhere. Expect for system administation and job scheduling, etc,. Tcl in Cisco iOS, Tcl in F5 Network appliances, A10 appliances, driving Git gitk, embedded in Python to drive Tkinter, and a scripting/GUI interface for R, CSound, Vtk, ns-2 network simulator... Tcl needs positive stories and it's successes pointed out, not "It could have been cool, but it's not". Regardless of where it sits in a popularity contest, Tcl is awesome, time-tested, rock solid... and _still_ improving. Best, -bch

I'd just like to say: Thanks for running such an awesome site! I use FlightAware to hack airlines by trying to locate the incoming flight that is to be my outgoing plane. Any plane landing ~60 minutes before my departure whose make and model matches my flight is a suspect. I can usually predict whether or not we'll have an on-time departure long before announcements are made.
- makmanalp 15y ago
  On time prediction, my friend, is a profitable business. Just in case you decide to quit your current job :)
- DavidChouinard 15y ago
  On some flights, we actually know what the corresponding inbound flight is. If we know, we show a small "track incoming flight" link and consider it in our delay prediction algorithms.
- cmelbye 15y ago
  Have you seen FlightCaster?
- rmc 15y ago
  ~60 minutes before my departure 60 minutes? Wow. Ryanair here in Europe does a 25 minute turn around. Often you're through the boarding gate and queueing up before the inbound flight has even landed.

Just wondering if you guys are setting the default language of the site based on the browser's location. The site opens up in Hindi as I'm accessing it from Bangalore.
- DavidChouinard 15y ago
  We do, unless you have (a) changed manually your language, in which case we save a cookie or (b) you're logged in and changed your language in settings. Also, (b) takes priority over (a).
