Sovereignty: Control level for a given solar system. Comes in levels 1-4 with levels 1-3 taking each a week to kick in and sov 4 being constellation sovereignty, which I won't try to explain for sake of the mental health of all of us. Sovereignty 3 is needed for Cynojammers and Jump Bridges (which, in a nutshell, allow for faster travel by bypassing the stargate network and getting friendly capital ships into cynojammed systems).

ISK reserves: ISK = Ingame money (InterStellar Kredits), which coincidentially has the same abbreviation as the Icelandic currency (where CCP is based).

cyno-jammers: Capital ships cannot use the ordinary stargates, but have their own jumpdrives that need to calibrate to what military experts call a Cynosural Field. Cyno-Jammers prevent creating cyno fields, effectively making a system immune to surprise visits by hostile capital ships.

capfleet towers: Where's that mentioned?

director level access: The other comment sums it up well, sudo. ;o)

This whole incident has nothing to do with Goonswarm infiltrating BoB with spies.

The person responsible was "just" a disgruntled BNC director that wanted to go out with a huge bang and GoonsFleet (The Mittani, to be precise) just gave him advice on how to maximize the damage he'd inflict on his way out.

And how many of those players play on one same shard? The massive part matters only if I can actually interact with those other players and the biggest US realms have about 35k characters of levels 10+ rolled on it. That's characters only, mind you.
I don't have any numbers on it, but if you could count only actual accounts/players (and/or players logged in at the same time), those numbers would be way less than that, too.

Anyway, if you're gonna go with this argument, EvE Online beats the whole bunch in that department without breaking a sweat. It's where the massively multiplayer aspect is truly massive with a peak of around 45k accounts (probably a bit less if you discard alt accounts) logged in at the same time in one persistent game universe.

And as we all know, pre-release versions of software behave exactly like the final product and any benchmark results from the pre-release are completely accurate because there won't be any more performance tuning.

Refactor your ints to long if you need bigger values?

Apart from that, the link's criticism specifically refers to Arrays still using a 32bit int index without the capability to use a long instead but you might be able to work around that by using another datastructure instead should you really need that much Objects stored in one container.
