Cunt... what is the recipe for haggis?
Aye?
Aye?
Aye?
DNA
Don't forget to prick your haggis.
Traditional Haggis (from Evelyn Hlabse, esh2@po.CWRU.Edu)
1 sheep's pluck (stomach bag)
2 lb.. dry oatmeal
1 lb. suet
1 lb. lamb's liver
2 1/2 cups stock
1 large chopped onion
1/2 tsp. cayenne pepper, Jamaica pepper and salt
Boil liver and parboil the onion, then mince them together. Lightly
brown the oatmeal. Mix all ingredients together. Fill the sheep's
pluck with the mixture pressing it down to remove all the air, and sew
up securely. Prick the haggis in several places so that it does not
burst. Place haggis in boiling water and boil slowly for 4-5 hours.
Serves approximately 12.
Serves approximately 11, if you invite me.
John
Yuuuuuck. You guys will eat anything. |
At one time it was traditional round these parts to eat offal called Tripe
and Elder. Bought wrapped in newspaper, from a Tripe stall at the local
market and boiled in milk or served raw with vinegar to taste. Sourced from
some unmentionable parts of a cows body and utterly loathsome to look at or
handle.
As a kid my parents tried to get me eat some and I still vividly remember
wretching after forcing some of this obscenity in my mouth.
It stuck with me. On business in other countries it was always a trial
dealing with whatever nighmare foodstuffs (delicacies!) the hosts could
come up with. Stuffed Goose throat, animal head parts, sea animals not out
of place in a science fiction film. Ugh!. Eventually figured that a
countries food directly relates to how close the population are to their
poor peasant roots. Gimme a lump of beef any day.

A callback is a function you register (store a pointer in a table, for
example) with some sort of scheduling routine that you want run when
some event occurs.

In the purest sense of things, ISRs are pieces of code that are called
when some (physical) event occurs and are run 'outside' of the scheduled
tasks. In many OSs, ISRs are actually split into two parts, the 'bottom'
and 'top' halfs. The bottom half is the code that must be run at
interrupt time to save I/O data, reset h/w for the next event and set a
flag or schedule a task to do further processing for the event. The 'top
half' is the scheduled task that completes the processing necessary to
handle the event. This might be referred to as a 'callback' in some
systems.

"I have a theory that all Scottish food is based on a dare"
(Mike Meyers)
I've tried haggis and it doesn't taste as disgusting as the ingredients
suggest.
The sheep's stomach is as thin and inoffensive as a sausage skin, and does
the same job of holding it all together. Sausage skins were traditionally
pigs intestines, but few people think sausages are disgusting.
As for the rest, only lamb's liver sounds bad but even that is okay if
cooked well (e.g. as a small part of a grilled lamb chop)
IMHO it just looks like a poor but canny Scots lass faced with a Spartan
pantry had a good go at stretching a small cheap cut of offal into
flavouring the largest portion of sausage-substitute.
I found it a bit dry. Needs a good gravy, or dampening with a splash of
whisky (oh yes, it's not just for cornflakes).
That is made of cow stomach, and is about 7 mm thick.
I hear it can be edible if cooked properly and even made to look okay (fried
in breadcrumbs like plaice).
But as you may know, we English are famous for boiling food to leach out the
flavour and vitamins into the water, then throwing the water away and eating
what is left.
| Quote: | As a kid my parents tried to get me eat some
|
That counts as child abuse IMHO.
Along with school dinners. The people responsible should have their livers
boiled for hours until grey and rubbery, then made to eat them. Dr. Lecter,
we have a job for you!

eating that". I bet he was bloody hungry.
And what is the deal with oysters?

That's a flag. Here's a good explanation of callbacks:

I don't think they are anything like squid. Squid are like tubes

cucumbers are more like really stiff gelatin in texture and have no taste
of their own and take on the taste of whatever sauce they are cooked in. |

My (perhaps non-professional-programmer) definition of that is
"relocatable" or "PIC" (position independent) code.
"Pure" code is code that has no associated statics and if of course
not self-modifying, so that it can be executed by multiple threads
without hassle.

A simple flag does not constitute a callback, what you are
describing is simply persistent memory.
Callbacks are used when a routine (typically event driven),
doesn't know what else needs to be done for an event. All it
knows is when the event occurs, if there is a procedure address
defined, to call it (back).
If you look at publish/subscribe, you have a multiple
call back situation. Every client subscribes to the
event by passing an execution address which the
publisher (server) keeps in a list. When the event
occurs, the server "calls back" all the functions passed
by the subscribing clients.
Of course, publish/subscribe can also be done with
messages or signals, too. The end result is pretty
much the same. (Though nigglers will tell you the
direct call back has threading and context issues...)
