Nothing stops you from leaking memory in Rust either, it is considered memory safe, see std::mem::forget. Rust only safes you from use-after-free and double-free.

I think I would just put all the nodes into a Vec and use indices instead of references. This results in every node having the same lifetime, like you wanted. It is what the specialized graph libraries like petgraph are doing, and it is mem

I'm already struggling to compare variables to strings. Sometimes the string will be interpreted as a variable instead of a string, and I don't know how to avoid that.

I think at the moment they use a level 1 hardware trigger and a level 2 software trigger. ALICE is moving to a pure software trigger.

It is accessible, just not with some specific software. From what I can see, they tried to solve it, but could not due to lack of cooperation by the software's creator. Maybe they should have spent more effort, but then this was not a

I don't understand how people can be so entitled about free software. Especially given the reply by the Qt developers: > The JAWS people didn't answer emails when we reached out to them (admittedly quite a while ago), so we&#x2

If you want to see the largest file, wouldn't you want to sort it by size anyway?

Funnily enough, the symbol for the newly announced particle cannot be written down with Unicode.

by whyever 9y ago
Just the math is not enough, you need some connection to reality. For instance, your formula does not describe reality for large v. This can be tested.

SymPy has Unicode output, you can try it here: live.sympy.org Note how "Symbol('alpha')" and "Symbol('x_a')" get converted to unicode. There are limitations though, "Symbol('x_b')"

They could just add a test that makes sure trivial comparisons still work.

> Cyclic data structures (without additional layer of indirection) require unsafe, or reference counting and dynamic borrow checking. Doesn't this apply to any language?

Signal has most of these features as well.

There is a train every hour. If you don't buy a discounted ticket, you can take any train you want. You can also take the bus, which is a lot cheaper but takes longer.

> instead of using one generic error type for all of them But you can do that in Rust, just use Box<Error>. No library does that though, because it is not a zero-cost abstraction.

What do you want to use inheritance for? In my experience, it is usually better to use composition and sum types.

How is nuclear waste clean? How is a possible reactor meltdown safe or cheap?

Yes, I don't think you can do better if forced to use &str. The point of using Cow is indeed to only copy when necessary like you assumed. You could have zero-copy roundtrips if you used escapes in the deserialized strings as well.
290.
by whyever 9y ago
It doesn't. You can use Cow<'a, str> if you want string escapes to work, but then it is not really zero-copy anymore.

Unfortunately Rust uses an LLVM fork IIRC, so using it is non-trivial.

Rust fares better in other indices.

I don't think the current state of systems programming is something to be proud of.

Tiobe as your main argument is not very convincing.

Can't you just use something like performance counters, like perf for Linux?

You can also have excited particles that have the same quark content. They are called "resonances", are unstable and can decay. For example, the five particles discovered here are excitations of the particle containing two strange

The Higgs is an elementary particle, so its discovery was much more exciting. There are a lot of particles made up of quarks, like the five mentioned in the article: http://pdg.lbl.gov/2016/tables/rpp2016-qtab-meso
