It really speaks to how great the technical team can be. As crazy as it sounds Goldman Sacks and JP Morgan both maintained 2.7 Python as a core language until just a few years ago (yes, it's still used in production).

Or insane

Python is used as a kind of 'visual basic' language in a lot of banks especially in front-of-house trading software, e.g murex or frontarena. Migrations between major versions of these can take years, costs 100s of millions and involve thousands of devs. Mistakes can be _expensive_.

It is kind of 'insane' but also, meh..

There's more dragons out there than we've been led to believe :}

> The classic example is division: in Python 2, 1 / 2 is 0; while in Python 3 it is 0.5. Can someone kindly explain this? edit: I misread it as “In Python 2 2.1/2 is 0, while in Python 3 it is 0.5”

From long ago memory: in Python 2, 1 / 2 did integer division. You had to do something like 1 / 2.0 if you wanted floating point division.

Spot on. Py2 was integer division, Py3 was true division. In Py2 you could get the true division with an `from __future__ import division` (Can't recall which Py2 version this became an import). Fun fact too: In Py3 you can do a // to get back to the floor division effect (e.g. 1 // 2 --> 0)

Can an experienced player gives us a summary of what's the "vibe" of the EVE online community these days? I was lightly involved ~15 years ago.

I too would love to know the answer to this question. I loved Eve as a teenager / young adult. It was a brilliant burst of nerdery, and the first time I ever met someone who wrote linux kernel modules for a living.

I sometimes think about logging in (I think I ragequit likely in a pod inside a wormhole in the middle of nullsec) and then I realise that way madness (and much sunk time) lies.

When python started incorporating asyncio my initial reaction was fairly negative. I was behaving like a grumpy graybeard programmer ("kids these days should learn how to use concurrency instead of working on a new runtime altogether!" [0]).

But after using it for a production project I have to say I'm deeply satisfied and surprised by the maturity, quality of APIs and performance in general.

I was proven wrong and I'm happy about that :)

Python is very strange programming language for a MMORPG. I'd imagine they would write it in C++ or something. They don't quite explain what they use it for.

And yeah, using a faster but safe language could help immensely.

Does the game have performance issues? I don't see the need to rewrite unless there is a problem with it

> Does the game have performance issues?

Yes, it has had huge concurrency issues for the entirety of its life. Their solution to large fights has historically been "let us know in advance pls", plus "move systems to beefier hw nodes" and "tidi" which stands for time dilation, where the "tick rate" of the whole server goes down and a fight takes 10-20-100x longer than it should.

It's an amazing concept of a game, but software wise it has been a mess since forever.

Yeah if I ever have the need to occupy an inordinate number of hours of my life again I’ll log back in, the temptation to dust of the account(s) arises sometimes. Think I managed to log off in lowsec but who knows!

This is why I had to quit. I enjoyed it way too much and would spend nearly all my free time playing it, much to the detriment of the rest of my (non-professional) life.
