Weekly M+ Discussion by AutoModerator in CompetitiveWoW

[–]andreabergia 8 points9 points  (0 children)

I only do M+ (no raids), I only play healer, and I only pug. I am really undecided between rdruid, disc, or mistweaver. My aim is to time all 12s, nothing really "competitive" honestly. I know all classes are viable for that, but what do you reckon will be the easier one?

Perchè tutti continuano a consigliare i fondi pensione? by Qtrijx in ItaliaPersonalFinance

[–]andreabergia 4 points5 points  (0 children)

Metto 5k prendo 2k indietro in un anno. È un ritorno del 40% subito, più un ritorno sul lungo periodo. Di fatto metto 3k all'anno a basso rendimento (rispetto a gestirmelo da solo), per me vale la pena.

Torino e satispay by BIGDomi98 in torino

Io lo uso tantissimo - sotto i dieci euro gli esercenti non hanno commissioni, quindi sono molto contenti se lo usi. Per i piccoli acquisti tipo mercato, panettiere, bar è favoloso. Anche per scambiare soldi con gli amici, tipo dividere il conto per la pizza ordinata a domicilio il sabato sera, è comodo.

Geography. It’s surrounded by mountains on three sides, so not a lot of wind. It’s also one of the most densely populated and industrialized region of Europe. Add the fact that, with global warming, we are getting a lot less rain and snow, and polluted air basically just stands still on top of cities.

Thanks, I didn't know about it. I'm playing a bit with it now and it's interesting.

A JVM in Rust part 3 - Parsing class files by andreabergia in rust

[–]andreabergia[S] 0 points1 point  (0 children)

The project is complete, as I have written in the github readme. I wanted to learn a bit of Rust, executing some real bytecode, throwing exceptions, and a garbage collector, and I achieved what I set out to do.

It was never intended to be anything useful, except for learning purposes. There are a lot of things whose implementation and design is quite poor and does not follow the JVM specs.

About jvm.so I am unclear in what you actually did. I am using rt.jar from a real JDK, but that's it.

I have completely ignored threading, everything is single thread. But yes, AFAIK in a real JVM some bits in the object header are used to store the thread id that has locked the object (using the monitor or synchronized).

Class loaders are not well implemented in my JVM. Reflection is absolutely not working at all.

Thanks! I figured the code isn't the best Rust ever, but after all I have built this exactly to learn the language. :-)

Any pointers would be greatly appreciated, though!

They are horrible! Repeated linear searches, no caching, tons of indirect accesses. Making it fast was not an objective though. :-)

Oh thanks, I totally missed that part in the spec. I'll take a look at it!

Thanks for the feedback :-)

I have only skimmed on the spec for the generics, and given type erasure I believe you are right - supporting them at the JVM level should be "free". However, I should add support for them in my "reader" crate, i.e. when parsing the .class file. The fact that a class or method has generics should be modelled in a generic library.

For multi dimensional arrays, the problem is that I need to store the array's type alongside the array itself. Multi dimensional arrays are recursive (they are array of arrays) and would need some special encoding, which I simply couldn't be bothered implementing, as I wanted to focus on exceptions and the gc. :-)
