Having the source code is more like having the blueprints to a lock than the keys. If the lock is a bad lock, then having the blueprints will make it easier for an attacker to bypass it, but if it is a good lock, it doesn't matter whether the attacker has the blueprints or not. Hiding the implentation behind layers of obfuscation is called security through obscurity and is generally considered a bad practice as it allows security flaws to stay present for longer than if the implementation could openly be scrutinised by everyone. Not only malicious hackers can look at the source code and find flaws in the code, anyone can.

As for the open-source discussion. Companies defintely don't frequently develop open-sourced software compared to how often they develop proprietary software. Almost all software I have installed on my computer is proprietary software. The reason for this is simply to make more money and prevent theft of code, not to enhance the security.

Not really. Most AC software is proprietary and owned by for-profit companies, and these very rarely make software open-sourced. Whether it's more secure or not is not a factor.

I think you should ctap as often as possible. No reason not to. If you fail you just need more practice (which you get by trying it as often as possible).

negligible or no packet loss:
cl_interp 0; cl_interp_ratio 1

non-negligible packet loss:
cl_interp 0; cl_interp_ratio 2

Don't spread misinformation. Setting these above the server tickrate (66.666 ticks/second) will not give you any benefits as that is the limit on how many packets can be received/sent. On the other hand, setting these higher than the tickrate can fuck up your other network settings.

The thread you linked recommends putting cl_interp on 0 so not sure why you are going against your own source. Also, I'd recommend using cl_interp_ratio 1 even on hitscan if you have a decent connection that doesn't drop packets. Higher interp ratios mitigates the effects of packet loss, but if there are no packet losses to mitigate it's not really necessary.

Nah, it was by far the most used unlock even before the passive reload buff. I think Mirelin was pretty much the only notable medic that primarily used another weapon than the Crossbow.

You can go back to i49 (2013) to see that it was the most used unlock by top medics. Hard to find any information before then as logs were not as detailed.

EDIT: For reference, the passive reload buff was added two months after this LAN.

If you are going to nerf the crossbow I think uber building should be removed (possibly in addition to removing passive reload). It will still be better than all the other med unlocks, but at least abusing arrows in the wrong situation will cause a significant uber disadvantage which good players can recognise and capitalise on.

(arrows used to not build uber and have reload time... it was still the most widely used unlock by far)

I don't really know what config is the best, but they should not have much difference between them in performance.

Use an up-to-date FPS config instead. Half of these launch options don't do anything.

TF2 was way bigger in 2010 than it is now. ETF2L used to have an endless amount of D6/D5 teams, now there's like 40 teams in open.

IGN has a full-game walkthrough on youtube, no commentary and plays objectives. Pretty good if you want to avoid annoying streamers. https://www.youtube.com/watch?v=52VT2A4UZt4

Still wish I had a VR headset though.

At LAN you don't have to wake up in the middle of the night to play. You will most likely have adjusted to the jet lag in the previous days if you come from other continents. Waking up in the middle of the night vs being jetlagged is a big difference.

The ETF2L nation cups are played on European servers at European times, so anyone not from Europe is very disadvantaged. It's a European league, so the nation cups are mainly for European countries. It is not really meant to be an intercontinental competition. North American teams usually get Chicago/East coast players for ETF2L competitions as it's possible to get below 100 ping, which is still playable. Oceanian/East Asian teams have never entered as they would have to wake up in the middle of the night to play a 300 ping official.
