- tla.pdf - numerous examples

The PDF describes model checking in TLA working through minimal background (fairness, model state etc.), application in TLA, two non-trivial models, and two appendices with reference background on TLA, and its procedural cousin PlusCal.

Let's not let politics' meaning become so diffuse it's just free speech by another name. Herein "politics" seems to be too inconsequential for a far more consequential result than cycling out party A for B for a few years would have.

I've half joked before that brexit was the only solution Cameron et al saw left because they didnt have a way to hold Brussel's paper pushers to account. Taking your ball and going home is not bold leadership: it's an admission one's argument and solution is weak.

Not so fast. They are in a union with other provinces ergo they have a say.

If nonetheless in some asinine way they secede, will they take their portion of Canada's debt, and other liabilities?

Won't all other provinces require them to negotiate a border, security, and trade policy? Surely they can't expect to be separate yet equal to BC or even the NWT?

It's the enlisted men/women who ultimately have to bear up under their choices: does their equipment work in battle or not? And tax payers to pay. As soon as the dod discovers they have ultimately accountability whence ultimate control things will balance better

And an aside: it'd be awesome if every round didnt cost 500 million+ ... I have recently been depressed to hear we spent a large majority of missiles etc in Iran. Iran? Really? How in the hell are we gonna deal with something serious? (Iran/oil is serious of course .. but Iran isn't china)

Reactionary. At worst young kids are lazy (in selected cases only) and nieve about how work works.

Entitlement comes from mental disorder or growing up in affluence like much of the upper 5%.

Moreover, kids from middle to lower income brackets i think work harder, are more resilient, and take their education more seriously than those that just fall in Harvard. The underlying difference? Consequences in the real world. When you always land on your feet or feel untouchable entitlement is 6 months away to a lifetime of clueless.

But this link has got me concerned. When I get more ibverbs work done ill see how good/bad it is in rust.

In this kind of extremely low latency high throughput work there is hardly any (mostly none) MT data structures. Memory is pre-allocated for one pinned thread. Atomics are not much used either. So rust isn't going to help on design much. But I think rust/c interoperability is worse than zig.

In fairness to zig many of these issues were closed when zig 0.16.0 was released, which is what im using.

We'll see

Apt install tells what it's gonna do. That's the standard to measure against.

Corporations have become entitled. Like the op i am sick of it.

Hence the jargon "completed infinity". Semantically --- but not in the symbols themselves 0+1+1..." one can pass from finite to infinite by arguing since every n has a successor define Z to be the set of all successors "completing into infinity".

Not having infinity is the real reason a+b=b+a can't be proved in ultra finitism. Induction which depends on the idea of completed infinity is what is otherwise is used.

You know what'd be great foreign policy? 100% energy independence preferably trending green. And thereto no more mideast wars. Or if we do get into one (and if our hand us forced), we no longer have to have one hand tied behind our back because of global oil markets, or the hormutz straight.

Allegedly a Spanish gov official quipped: every time the US helps other countries with democracy, it lucks out and finds oil. There is some truth to that.

It's talk by people with nothing serious going on. It's cheap, pointless pontificating.
