Both Debian and Ubuntu provide snapshot mirrors where you can specify a date to get the package lists as they looked at that time.

8MWh is equivalent to a few hours of electricity generation of a wind turbine.

One major downside is that it becomes really hard to do transactions, especially across multiple files. If you store mostly immutable data though like git (where except the refs every object is immutable, mutating creates a new object) it can work nicely.

I for one enjoy the convenience of automatically installing python versions. Yes I know how to do it manually. Yes it is possible to install multiple versions. But that does not mean I want to do it every time, just to test how things behave in different python versions. For that, it's also okay if it does not install the most performant version of the interpreter.

The limit could depend on a lot of other things. In theory, it's possible that you are paying 100% of revenue on debt service yet still the best option is to take on more debt. This is if you believe that investing the money raised via additional debt provides returns that outweigh the increase in debt service costs. So in that situation, additional debt can even lower the debt service / income ratio.

So this is meant to illustrate that the limit on debt is more a function of the concrete circumstances. In this line of argumentation, debt is not limited by a mathematical formula that just takes GDP and similar statistics as input.

My argument is that you typically also check other properties, like properties describing what your program should do. These other properties likely wouldn't be satisfied by a nop program, and hopefully the same is true for many subtle issues.

Yes, that is a limitation. But this limitation is not too bad.

In many cases, a bug in the translation simply makes the proof impossible. Somebody then investigates why the proof does not go through and finds the bug in the translation.

We only have a problem if the bug in the translation specificially cancels a bug in the original code. If there is no systematic risk, it is quite unlikely that two bugs cancel each other in this way.

Do you know if redispatch costs are included as part of your transmission costs and how much they are? Because if they are, then investing into the transmission lines can decrease transmission costs since the providers need to pay less for redispatch.

I am no economist but couldn't it be that raising pay in few sectors does not cause inflation? I would think that depends on what the people receiving more money spend it on. If they only spend it on things where we have no bottleneck and there is still excess capacity, how would that create inflation? Inflation should only happen if the increased paycheck is used to compete for scarce resources/products. So I think predicting inflation requires a more detailed analysis, especially you need to have a cycle of increased prices and pay.

How does rust do bounds checking for slice accesses if the length is not stored?

JVM also has jstack and other tools like jprofd to introspect running vms.

Construct a TM which enumerates all possible variable assignments and checks if the SAT problem is satisfied then halts if so. You can construct this TM in polynomial time, and it halts exactly if the SAT problem is satisfiable. So this is a polynomial reduction from SAT to the halting problem.

But it breaks down if you have cross-language cycles, because no garbage collector of either language will see the full cycle.
