I think nonces are generally thought of as numbers, and as a client it might be simplest in some cases to be able to reuse or derive from an existing non-number key.
"The information included names, email addresses, credit card information such as credit card numbers, expiration dates and the three-digit CVV code found on the back of credit cards, although BA has said it did not store CVV numbers."
Is it standard for airlines to handle storing payment card details themselves and hence having to be PCI certified instead of delegating to a PSP?
Maybe, as a first shot, they decided to favour near-instant implementation over usability by simply setting the price for an existing product to $0 and use the existing checkout flow.
One of the declared goals during the initial design phase of the Haskell language
was to "... be usable as a basis for further language research." From "A History of Haskell: Being Lazy with Class" available at https://www.microsoft.com/en-us/research/wp-content/uploads/.... Language pragmas feels like a nice tool to support this goal.
Anyone know of a reference for "The keyboardist Joe Zawinul was aghast at Davis’s ruthless arrangement of “In a Silent Way,”... " part?
It is difficult to prove a statement like "..he pioneered hard bop.." wrong, but it is definitely a new view on the history of jazz in the post bop era.
I use issue tracking, having a list of 3-5 next features I would like to implement. With a detailed description of the feature and potential upcoming challenges, this works well to get back in the groove when having been away from the project for some time.
A classic, and clear, example of "elementary" meaning something different than "trivial" in math, is Atle Selberg's Annals proof of the Prime Number Theorem. A link to notes on this proof, and some (!?) controversy relating to it, here: https://people.math.osu.edu/nevai.1/AT/ERDOS/ErdosSelbergDis...
PDFBox is quite good at extracting text from pdfs. When I use PDFBox, it is for extraction.
Maybe this has changed with newer versions of PDFBox, but 5+ years ago, the internet wisdom was to use PDFBox for extraction and something else, like a version of iText that suited your license needs, for generation.
As much as I like LaTeX, if you have made no prior time investment in typesetting with it, it is not trivial to produce custom good-looking output with it.
Have you tried using (La)TeX in a real world project? Would be cool to hear from someone on whether compilation time is an issue. Some TeX packages have a quite severe impact on performance.
Notes in different octaves are different and hence should look different. Even if you restrict to keyboard instruments, I am not sure you describe an existing problem with classical notation.
For the non-keyboard instruments I know how to play, tones in different octaves having different identifications is a must unless you want to add extra parts to the notation.
Listening to that reminds me of a joke you will likely hear multiple times if you play bigband gigs: How do you get 2 _your_own_instrument players to play unison? You shoot one of them. How do you get 2 _other_guy's_instrument players to play unison? You shoot both of them.
