SteamTracking VS SteamKit

If you want to test ping and routing directly to the closest Valve server site, the IPs are publicly available.

The 32-bit version of Steam works, so they’ve not bothered to compile 64-bit binaries for 64-bit versions of Windows and Linux. There’s already a mechanism in the Steam client updater for delivering different binaries depending on version of the OS and 32/64 bit, take a look at the client manifest and note the variations of “bins_cef_win32” for “win10-64”, “win7”, etc. So, it wouldn’t be a lot of work to distribute 64-bit versions of the other Steam client binaries because they could use the same mechanism to deliver them.

Quick bit of google-fu led me to this https://github.com/SteamDatabase/SteamTracking/blob/master/Random/NetworkDatagramConfig.json

The new cluster has been up for a couple of months already, but seeing as it only just now got its string it's worth mentioning anyway: the EU West server cluster (as it's known in Dota 2 and CS:GO) has been relocated from Luxembourg to Frankfurt, Germany

It really does suck that they've not put out an Apple Silicon / arm64 update, I'm sure that just switching the Intel version of Chromium Embedded Framework (CEF) in the Steam Helper for an arm64 would help a lot. They put out multiple versions of the web helper and CEF binaries for Windows so that they can support 32-bit Windows 7 as well as newer 64-bit versions of Windows, but according to the Steam Hardware Survey, only 0.12% of Steam users use 32-bit Windows 7, while 0.89% of Steam users are using Apple Silicon CPUs (40.7% of Macs on Steam are using Apple Silicon CPUs, 2.2% of Steam users are on macOS, 2.2 * 40.7/100 = 0.89)

Steam itself draws everything in its own windows, including the 'traffic light' buttons which are weirdly spaced in the OP's picture. They're actually TGA images distributed with Steam, not part of the OS.

Real answer: the SteamTracking repo (not to be confused with GameTracking, which facilitates and provides rapid teardowns) has a list of URLs it keeps eyes on, one of those being Valve's people page. Its frequency used to provide updates as quick as 15 minutes, but these days it's been relaxed to around once an hour, a short time after the top of the hour.

OS type have next values:

I've managed to find older versions, but not that Bluetooth BLE firmware version. It seems to have never been included in the firmware.vdf https://github.com/SteamDatabase/SteamTracking/blob/master/Random/ControllerFirmware.vdf

xPaw (guy from twitter and SteamDB owner) is a data miner, so he tracks every Steam's API update, he even makes it public, so anyone could also compile and do the same thing from his screenshot.

So I will be making a client-side mod to show mmr changes as in the old client Upcoming data will be stored locally in the cfg folder (per account i.e. cloud synced) Wont know about matches played before adding the mod (valve went scorched earth removing data points from client.dll) But can populate previous history via an external opensource tool based on SteamKit samples

Or also you can check this or this github repositories, which emulate steam client (Or any other, there are lots of them)

Depends on what language you're using for JavaScript I think the defacto is anything Doctor McKay makes https://github.com/DoctorMcKay/node-steam-user, https://github.com/DoctorMcKay/node-steam-user etc. If you use python, I'd recommend https://github.com/Gobot1234/steam.py (I'm totally not biased). If you use C# then SteamKit is always a good option. If you use rust then SteamHelper looks interesting although doesn't support too many trading bot features

Me: Okay. I'm just going to prototype a game. Don't want to get carried away. I won't even write a game engine. I'll use Tabletop Simulator.

Friend: Sounds good. How's it going?

Me: Well. I needed to be able to debug my code. https://github.com/tts-community/moonsharp-tts-debug

Friend: Oh, neat. So your game is done now?

Me: Not exactly. I had to had in matchmaking by reverse engineering Steam. https://github.com/SteamRE/SteamKit/pull/704

Friend: Ah. Alright. Can I play it now?

Me: Nah, I was finding it hard to maintain code. I wrote a Lua code bundler. https://github.com/Benjamin-Dobell/luabundle

Friend: Sweet.

Me: Yeah, but I decided to integrate it into the official tooling. https://github.com/Berserk-Games/atom-tabletopsimulator-lua/...

Friend: I'm sure the community will be thankful.

Me: I hope so. I now run a small community of TTS developers. https://github.com/tts-community/

Friend: Right. You must be done by now.

Me: Nah, I couldn't statically type check my code. So I wrote some types. https://github.com/Benjamin-Dobell/tts-types

Friend: Seems unnecessary for a prototype, but sure.

Me: I had to write my own IDE to use them though. https://github.com/Benjamin-Dobell/IntelliJ-Luanalysis

Friend: Right... So how'd the game going then?

Me: Oh, I'm not doing that anymore. I now consult for Berserk Games, developers of Tabletop Simulator

Friend: ...

I don't know any direct resources for learning how the Steam network works, smart people figured it out over many years and lots of reverse engineering. I just know a few programming libraries which you can use to interact with it, the most popular two being Steam-User (JavaScript) and SteamKit2 (.NET).

It's possible to do it through Steam's internal protocol, you probably want to use SteamKit2 here.
