So I have this embedded SVG mess I'm working on, and being embedded, compromises are often to be made.
One of them is that I don't validate the SVG beyond what I need to parse it. This reduces flash space requirements, and sometimes memory requirements, and can also reduce power/increase execution speed in the margins, although sometimes with more dramatic effect.
Consider the following values for the transform attribute. There can be multiple in a list separated by spaces:
rotate(-10 50 100)
translate(-36 45.5)
skewX(40)
skewY(10)
scale(1 0.5)
matrix(0 0 1 0 1)
Also the space delimiters above may or may not be commas, just to keep things fun, and some of the arguments presented above are not necessarily required
The above would do six transformations in series, as each transformation is presented along with the others, separated by whitespace, resulting in 5 matrix multiplications.
The issue is parsing it.
I don't want to validate all this, because I don't care. So I do things like this:
switch(**current) {
case 'X':
ttype = TRANS_SKEW_X;
state = -1; break;
case 'Y':
ttype = TRANS_SKEW_Y;
state = -1; break;
case 'k':
case 'e':
case 'w':
++(*current);
break;
default:
return FMT_ERROR;
}
That's all a single state in a larger state machine (not pictured). I've "compressed" (lossy) the parsing of skewX vs skewY into two states, with the final state being shown.
Normally you need like N+1 states where N is the number of characters in the phrase you are parsing.
Here, it will except sekwX for example, but what are the odds that you DIDN'T mean skewX on top of the odds that it happens in the first place?
It's a compromise. This is a renderer, not a validator.
But it got me thinking about approximated state machines like this, and I'm trying to sort of float some codeish equations in my head for how to represent them algorithmically, and I'm not seeing it.
I've got "concepts of a plan", is all. That won't get me far.
But it's interesting to me, the idea of compressing state machines in order to approximately match text. I can easily see the use in embedded.

I've never eaten any of my neighbors' pets. Have you? Why or why not?
|
|

Most of my neighbors have dogs or cats and I've never been tempted to eat them. One previous neighbor had chickens and I was tempted, but one of the cats ate one first. In Venezuela, iguanas were running all over. I was invited for some iguana stew and it was terrific, but I don't know if that counts as a pet.

I'm so glad you provided a reasonable answer. This web forum has members that span the world. I'm pretty sure that eating a pet is illegal in the U.S., at least at the federal level AFAIK, but honestly... What constitutes a "pet" versus an animal raised for the purpose of consumption as sustenance?
I once ate alligator nuggets back when I lived in Phoenix. You know what? They tasted like chicken. If there is at least one human being who owns an alligator as a pet, then I must confess. I've actually eaten an animal that people keep as pets.

I just realized I once ate rabbit while living in the UK. My niece owns a pet rabbit...

Reminds of scene from "Local Hero"
Reaction to eating a rabbit.
"It was a pet, not an animal.
It had a name, you don't eat things with names, this is horrific!"
Great movie. Music score is Mark Knopfler (sp?) inspired.

Up to that point I thought "Local Hero" was a restaurant, and you were describing someone's reaction to someone else's ordering that off the menu. 
In my defense, there are a few bar & grill type of restaurants in my area called Local Heroes. I don't think they serve rabbit however.
I've always said, the cuter the animal, the tastier it is.

You've never had a farmer as a friend?
Decades ago, friends of ours invited us over for dinner. He farmed peanuts, wheat, huge vegetable garden and he was really working on breed stock for beef. At the time, he had one tied up near the house. So, about a month later, we had been invited again for dinner and while grilling I asked where the cow was... he smiled at me and lifted one of the steaks off the grill.... "don't tell the kids..."
If you can grill it, you can eat it. It's all perspective. There was a book written years ago "Coming Out of the Ice: An Unexpected Life by Victor Herman" that will give you a real clear perspective on the insanity rampant in Soviet Russia. He survived by eating rats. Most people were grossed out in the gulag (and died). Toward the end of the book, he mentioned that to this day, if he sees a rat, his mouth waters.
Would I eat my neighbor's pet? Not willing? Would I eat a rabbit, cat or dog if I was starving or my family? Absolutely.

My grandfather was a farmer. Some of his brothers were too.
I've always found farmers were the most down to earth people (quite literally) you'll ever meet.
They also eat well.
I remember one of my uncles saying he worked on my grandfather's brother's farm as a kid. Dirt poor, but his table was always full, and the rule was - help yourself to anything you want, as much as you want, but you have to empty your plate.

Linux From Scratch!
So, I'm making an app (huge shock), and this app will be the only thing hosted on a dedicated VPS when all is said and done. It doesn't need much umph right now during development, so I'm putting it on a cheapo VPS with one VCPU for now. Ok cool, but that's essentially one core with no guarantee it'll be hyper-threaded. I mean, lscpu reports more than one, but it's a cheapo VPS I've had lying around for years that I never used. So, there's gotta be throttling.
These days, every dependency is built with multithreaded support by default, say if you use system packages from Debian or Ubuntu. And that makes sense, BUT... If your machine is only rocking one core, multithreading is actually slower. So, it would behoove me to rebuild the dependencies like libcurl to only use a single thread. Or, just get a beefier VPS for this app, but I got this VPS for another year, so may as well use it for testing.
Dunno if anyone has ever built libcurl from scratch but it's a long, painful process if you want proper support with protocols and whatnot. However, dun dun dun...
The folks at LFS (Linux From Scratch) pretty much give you step-by-step instructions on building curl... which in turn means building libcurl. And it's kept up to date every six months. These folks are awesome and this and Gentoo are the only distros of their kind.
Note: Ok, realistically I'll just pay more for a better VPS when this thing is ready to go live and the performance delta during testing is acceptable. Which means its back to multithreading any way I slice it. But... but but but... there's still the cool factor of building your own deps for static linking. Never forget the cool factor.

Gave up on Linux awhile back.
This has renewed my interest.
Thanks.
BYW, somewhere in my pile of distros over the years,
I have one the first Linux mass distros.
Now I am inspired to find it.
On CD, floppy?

Yeah man Linux is great. I mean itβs also a huge time sink.  But itβs the thinkerβs OS. I sure canβt make a custom build of anything Windows to suit my purpose. And you shouldnβt always do that on Linux, but you canβ¦ if you need to.
On my phone so canβt quote. But, I dunno if the first distribution was a floppy. Kinda curious. I got into Linux back into the CD days. Me and a buddy used to collect them like candy.
