Likewise: I think I have them all, and they are all read several times.
I have two copies of one (The Last Hero) because I bought it when it came out, and my elder brother queued for hours to get a copy autographed by pTerry for my birthday ...
Oh, and I bought them again in electronic format when I switched from paper to eReaders.
But the hardest one to read was The Shepherd's Crown - I had it for months before I read it; I just couldn't face reading it knowing it was the last ever pTerry I'd read for the first time.
I'm a sad old bugger sometimes!

Sir Terry is (was?) one of my all-time favorite authors.

Of the first four five or six I don't recall now how many of Mr. Yusuf's first albums which are in my collection before he became Mr. Yusuf that was the one and only song I did not care for However I enjoyed seeing him in concert via the link you provided something I only did once and happened to be live however I had the nose bleed seats and couldn't pick him out if he was my brother - Kind Regards

There’s a support group for people who can’t stop talking. It’s called On-and-On Anon.
I’m going to bed, so I’ll get my blankets. It’s cold here.
What do you get when you cross a joke with a rhetorical question?

Do questions with multiple question marks annoy you???

My wife once told me that I needed a support group for recovering backpackers. I told her that 12 steps wasn't a very long backpacking trip.

I just love them. They're like little puzzle pieces you can use to solve really complicated problems.
I can't stand debugging them, but I love creating them and watching them make the compiler do really neat things in funny ways.
I don't look for excuses to use them, because they're hard to debug, but I enjoy them when they are the right tool for the job. They're incredibly versatile, and I think fun to create.
Does that make me a nerd?**
** It's okay if it does, I'm just looking for a frame of reference.

Hard to debug because when you have chains of them it can be hard to know which ones are even being compiled.

In my GFX project I allow drivers to expose different methods depending on what their hardware supports. GFX will use them when available for better performance.
You tell gfx what you want by exposing a caps "using" and filling it with what you support like this:
Supports only batching:
using caps = gfx::gfx_caps<false,false,true,false,false,false,false>;
Supports everything but read ops and direct blts:
using caps = gfx::gfx_caps<false,false,true,true,false,false,false>;
Each of those fields has a named argument to tell you what it is, so it's not as confusing as it looks.
If you mark a field as true, you *must* implement the methods necessary to support that feature. For example, if you mark your target as readable, you must implement the method to read a pixel from its framebuffer.
This caps template is examined through partial template specializations, and the different methods are called based on its values. It chooses the best method it can to perform an operation, and falls back when the caps doesn't support it.
This isn't really possible to do any other way, except at runtime, and that comes with lots of overhead and additional code size for unused code.

This is graphics related, so it took me a moment to realize that caps meant capabilities, not capitalization. 
I think you want to flip the trues and falses in the second example.
I assume the non-template way would be to have an abstract Driver class define virtual functions that return false, with each driver overriding the ones that it supports and returning true?

No, there's actually more read operations than write. Although posting that did make me realize I turned off asynchronicity on that driver. Edit: Never mind, async is not supported under Arduino. I forgot I was looking at that and not the ESP-IDF driver.
Yes, the non-template way would require a virtual class, but then it couldn't do things like taking non-native pixel formats. Every pixel format is its own type. gfx::rgb_pixel<16> nets you a 16 bit RGB pixel, but it's a different type than gfx::rgb_pixel<24> or gfx::yuv_pixel<24>;

For readability, you could introduce a new type/enum for each parameter that converts to a boolean.
That way it would say BATCH/NOBATCH, etc
If you have a unique type for each cap, then you could not accidentally transpose parameters in the long list of booleans.
I think you could figure out a way that the compiler would enforce it all without making the runtime any larger?
My C++ is very rusty, but I have faith that you can figure it out if you think it has merit. 😊

Yeah, I could do that, but with approaching 600 downloads here, and with over 30 stars on github i'm not sure I want to make such a big breaking change. caps is used *everywhere*

No you can't delete your post because it has sub items. OTH you can while playing with the URL
[Edit]
Doing that will not delete the thread, it will only delete the content of the top message and show it something like 'Message Closed'
