Squad did try to start working multiplayer into the game in 2014. The fact it was mentioned as early as January 2014 (and probably earlier) and they were still trying to "wrap their head around it" in November shows just how difficult and time-consuming the effort was, so it's no wonder it was (apparently) quietly dropped. Squad's last mention of working MP into KSP was Aug 2015, and that was merely in reference to a bigger framework. Here's a search for everything Squad has had to say about Multiplayer in KSP: https://forum.kerbalspaceprogram.com/index.php?/search/&q=multiplayer&author=SQUAD&search_and_or=and&sortby=relevancy Since these old posts didn't get through the forum updates cleanly, I'll quote the relevant parts... So, to sum up: (I have made a couple of memes about this too... https://i.imgur.com/eDa95O3.png and https://i.imgur.com/6VPdSq2.png)

Well ya, I knew about the dirigible-based craft, but I hadn’t heard about the Russian Zveno project. That’s much more Kerbal -
For Questions That Don't Merit Their Own Thread
StrandedonEarth replied to Skyler4856's topic in Science & Spaceflight
First, a disclaimer: I'm not a mechanic of any sort, but I did read a lot of Car Craft and Hot Rod Magazine during my car-nut teenage years. Unfortunately, I never had the budget for all the fun things I read about. My first car was a CheVette. So I'm heavy on the theory but short on the practical experience.That said... The quick answer to our question is that I don't expect any balance issues with a hybrid camshaft, as long as it's not an oddball engine with 2 (Alfa Romeo), 3 (GM), or 5 (Audi) cylinders, but it might be easier to have a rocker arm that activates two valves from one cam lobe. As for the long answer, I'm going to delve into some theory: Contrary to what most people think, an ICE runs on air, not fuel. The more air you can get into a cylinder, the more power it will produce, if you add the proper ratio of fuel. The fuel is just there to heat the air and make it expand. A running engine produces a vacuum that sucks air into the cylinders (okay, so it's actually being pushed in by outside air pressure; semantics), so you have a moving column of air running into the cylinder. The bigger the intake area (intake runner cross-section and valve area), the more air you can get in with a given airstream velocity. The poppet valves interrupt this flow, so the airflow backs up behind the valve, but the air farther back in the intake is still moving. In a properly tuned intake, at the RPM the intake is tuned to, this momentum "charges" the air (like a turbocharger or supercharger) so when the valve opens again there's more pressure pushing more air into the cylinder. Again, this ram effect is at its strongest at a certain RPM, and that RPM requires a certain speed of the airflow, which depends on the area available for the air to flow through. So, back to more air = more power. To get more air in at higher RPM, you need a bigger intake runner and more valve area. Having two valves for intake (or exhaust) provides more valve area in less space than a larger diameter valve, so you can fit more valve area into a cylinder by having more valves. But at lower RPMs, the engine doesn't need nearly as much air, so the airflow is slower for a given intake area, so the "ram" effect disappears when the intake area is too large for the RPM. So much so that the airflow through the intake can (nearly) stop when the valve closes, and it's harder to get a larger mass of air moving again. This results in a poor signal to the fuel metering system (carburetor; or airflow sensor in an EFI system) and poor throttle response, not to mention less power because the less air gets in the cylinder due to the slower speed. If you've ever slammed the throttle open at idle on a four barrel carb with mechanical secondaries, you've experienced this bogging out. Vacuum secondaries delay the opening of the secondary barrels until the RPMs are high enough to generate enough vacuum to get the air moving quickly. So at low RPMs, a smaller intake area can help maintain the ram effect, and gives better cylinder filling (more power) and better throttle response. Manufacturers have come up with several ways to try and get the best of both worlds (good low RPM response and more high RPM power). The simplest may have been Chevy's LT-5 engine which debuted in the 1990 Corvette. It was an all-aluminum, 5.7 liter 32 valve V8. It had 16 intake runners, and half of them had a butterfly valve which only opened at higher RPMs (if not locked closed by the "valet mode"). Another aftermarket solution I saw in those old magazines had matched intake manifolds and exhaust headers with different sized runners, which effectively split an engine into two smaller engines tuned for different RPMs. This split the torque peak and resulted in a flatter, wider power curve, with overall more power under the curve but less peak power. Your hybrid solution (some 4V cylinders and some 2V cylinders) would have the same effect as this approach, and would be more effective if the intake and exhaust are hybrid-tuned accordingly. Many modern engines use Variable Valve Timing technology (like in the 3.6L 24V Pentastar V6 in the Caravan I used to own) to extend the power curve. Advancing the cam timing moves the power curve to the higher RPMs (IIRC) and retarding it does the opposite. VVT gives the best of those worlds. The biggest potential downside I can see with a spilt torque peak approach is vibration issues if the power output between different cylinders is too great, but beefier (and likely heavier) engine mounts and flywheels might soak that up. -

Why is the engine plate a decoupler?
StrandedonEarth replied to Frostiken's topic in KSP1 Discussion
Well, I'm pretty sure that how they work was explained somewhere in the old DevNotes during the development of MH. My main beef with the engine plates is that the decoupler symbol stays in the staging stack after the stage below it has been staged away. Maybe a tweakable option to remove it, like docking ports? Hmm, those can only be tweaked into the staging stack in the VAB, no? -

Do the fairings even have any sort of guidance or do they jus do a “dumb drop?” They must have something to predict where the fairing will reach net height. It looked like they may have had the problem of the chute pulling the fairing off the net -
Make RTG units have halflife
StrandedonEarth replied to lajoswinkler's topic in KSP1 Suggestions & Development Discussion
I happen to agree. They’re kinda heavy, kinda expensive, and even two of them (for balance) don’t provide a lot of power. I use them to keep the batteries charged and/or backup for when I forget to deploy solar. -
Make RTG units have halflife
StrandedonEarth replied to lajoswinkler's topic in KSP1 Suggestions & Development Discussion
If you park something for long enough, you can charge up a battery, even with a 3/4 decayed RTG. If the battery is big enough, you can get some useful stuff done before it dies. Just saying that if more realistic power is the goal, it doesn’t end with a decaying RTG. -
Make RTG units have halflife
StrandedonEarth replied to lajoswinkler's topic in KSP1 Suggestions & Development Discussion
Besides, with a half life, it could still be trickling out power for a century, enough to charge a battery. Next we’ll need to limit the number of charge cycles or usable age of batteries? These little realism tweaks can trickle down and never end. -

Our townhouse complex is 20 years old. They’ve had to fix three broken pipes in the last 18 months or so. Woke up this morning and had no water again. I hope it’s back on when I get home from work... Obviously they need to replace the whole water system in our complex. At least the strata has a healthy contingency fund, a product of high strata fees. Better that than being charged special levies for this sort of thing. The roofs were just done last year...

There's a neat effect below -45C, when streetlights shining downwards have a column of light going straight up above them. Something to do with ice crystals falling in a flat orientation.
