Oh and the carriers all insist on using a specific currency conversion table for the day. We had a whole bunch of them. Nobody really defines currency rates. And there are a lot of them. I already mentioned several hundred of timezones. IIR

And that's just the fares. We didn't talk yet about seat availability. You have to ask for seat availability for the complete fare-component, the thing that a fare covers. So if you go Boston-Copenhagen-Hamburg you don't jus

Another example from my 2006 conference notes. Assume you want to go from Easter Island to Aalborg, Denmark. Not a commonly traveled market. Cough. Just the number of fares filed by the data directly for this route is 57. Direct fares (f

I would say the lack of limitations is the problem. Quoting from my notes for my 2006 conference talk: The Easter Island west of Chile has - One flight departing today, one flight arriving today. Friday there was no flight at all. - far

I still have a bad bug with those versions. Anyone else? https://github.com/zfsonlinux/zfs/issues/8396 Basically, when serving NFS from a Linux-ZFS the client can read/write/seek fine, but on-demand

Exactly. You have to realize the difference between a "pricing search" and a "low fare search", to use ITA terminology. A "pricing search" knows which specific flights it goes through and you just find the fare

Actually the whole cl-jupyter concept (used in the Cando demo) might also qualify. You can build really impressive blends of text-based statement and GUI in a webbrowser with Jupyter notebooks, and the CL version really kicks ass. I need to

Common Lisp has a package manager/source repository called Quicklisp. https://www.cliki.net/Quicklisp%20tutorial There are some web frameworks in there that are fairly impressive. There is very little advertising going

That is me, I'm half of that team (Martin Cracauer). If you have any questions I'd be happy to answer. If you want to learn more about the programming side of our work (not so chemical), check out our other videos. They are from p

Well, keep in mind that "macros" in Lisp are really compile-time computing. In Lisp you have the same language at your disposal at runtime and at compile time. In C/C++ you have the preprocessor, which is a really lousy langu

Not to mention almost all US based carriers and many others use ITA's flight search service to power their own (the carriers') websites. They can't search in the data they created, so they have to pay ITA. The data is complic

That guide is mostly what the reservation system used (now canceled). At the time of the merger QPX (the flight search) was ... diversely styled.

There are some feature in matrix that flights didn't pick up. The original matrix site was even more powerful and exposed some operator-ishness, depending on what kind of account you were granted.

Speaking of all this, am I the only one where NFS clients with executables on NFS (such as PXE booted machines) get bus errors when the server runs recent 4.19/4.20 Linux kernels with recent ZoL code? As a reminder, those bus errors ar

Well, there are a lot of those, they need to be looked at separately. What I (and the QPX school if I might use the term) use is compile-time computing, aka a programmable programming language. LLVM never gets to see this, by the time you p

I use the "punch holes" phrase in the following situation: - GC is copying/compacting - GC is at least slightly conservative - allocation is fast/inline/increment-only - that leaves you in a situation where you cann

This has been revised and clarified. I now use a whole bunch of terms that I find are useful to communicate personal attention patterns to those who didn't think about them so far: attention sponge, liking focus patterns to vehicle typ

Every time you make one assumption when coding, you leave it in one place and never spread it to other code pieces. Everybody wants to do that, but it is all easier said than done with current tools. Writeup comes in parts: 1: https:/

This is one reason why I'm so happy about the Raspberry Pi. It is not that the Pi as such added anything to the world that wasn't there before. But it is small enough to do the little things I always wanted while still running

The point is that you want to use the high frequency to get the simpler tools you will need out of the way, preserving your energy and attention for the complicated parts. If you used up your energy by the time you made it through the simpl

I apologize for the swipe at "toy languages". I tried using more common languages like the usual scripting crowd, but it wasn't successful, mostly for performance reasons. Python in particular is frustrating since the very ow
