Most of the true VRChat experiences happen in invitation-only rooms. It’s one of the apps where networking and growing a friends list makes a huge difference in terms of knowing where the party is happening.

Fermentation is a natural process, so there’s no energy input to the process. As for output, you get almost the same energy density as standard diesel, and some excellent fertilizer. For a farming area, it’s very self sustaining. Farmers bring their excess crop waste and manure, they get fuel and fertilizer in return. Also, the methane that off-gasses during fermentation is collected and burned to supplement the power grid.

Considering it’s mostly being used in this application, it works very well. However, I can see it falling way behind if scaled for widespread use in industrial and non-argricultural uses, where dedicated crops would be grown and harvested. Regardless, it’s a good way to cut down demand for standard fuel products for areas that can sustain a large biofuel digester.

The most common method of making biodiesel that I know of involves fermenting farming byproducts, namely corn stalks and manure. However, it still produces CO2 when it combusts.

The article doesn’t go into much detail about the production or makeup of SAF, but it sounds like a form of biodiesel/biokerosene.

Sounds like you need a new doctor

So, how did it taste?

I certainly would. Going public is always the precursor to enshittification.

Every courthouse I’ve been to in my area will not allow cell phones inside. Must be a state-based or county-based thing.

They’ve maintained a very pro-consumer stance so far; so yes, I do believe them for the time being.

Bethesda’s formula is pretty dated. They changed up a few things for Starfield, but it’s still same the old dialog system.

Us poors can’t bring cell phones into the courthouse.

I have not encountered any picocells on aircraft yet. Plenty of airborne wifi service equipment and some wireless mQAR’s for uploading aircraft monitoring data once the aircraft parks at the gate, though.

I do specialize in avionics, though. Hence, the more in-depth experience with navigation systems and radios.

Yes. The Rockwell-Collins radio altimeter system was lacking a low-pass filter in the transceiver, which was not a necessary item until cellular companies started rolling out 5G networks. Even still, with the highly directional nature and short range of SHF, it was assumed there wouldn’t be interference at first.

During landing, if the right kind of object happened to pass by in the right location at the right time (such as a car driving down a road close to the runway, bouncing a 5G signal upwards as a plane passed over); the radio altimeter would suddenly get a signal that didn’t make sense and kick off the Autoland system, warning the crew who is ready to take over immediately. It’s very likely no passengers ever noticed the transition of controls.

As for the fix, Service Bulletins were issued to check antenna and transceiver models on all aircraft, and replace accordingly. It took my airline a few months to get through all of our planes. We have a very large fleet, and I was even servicing a few aircraft a night myself.

Regarding GPS interference, a GPS antenna is a receiver, not a transmitter. More GPS enabled devices around it will not affect performance, as they’re all listening to the same frequencies. WAAS is also broadcast and received in a similar fashion and frequency, which is where you get down to Cat III levels of accuracy for Autoland.

As for bands, cell phones are sectioned to ~700-900 MHz and some small ranges above ~1700 MHz for VHF. VOR navigation operates between 108-118 MHz while GPS sits specifically at 1575.42 MHz (L1), 1227.6 MHz (L2) and 1176.45 MHz (L5) with WAAS and SBAS sticking close to those. From a VHF standpoint, a cell phone will not cause interference. I can also confirm this by goofing off with my phone while using an IFR4000 test set and watching the nav display indications in the flight deck.

Now, SHF is where things change a little bit. SHF is very directional and fairly short range. It will not make it inside or outside the metal tube of an aircraft very easily. Although the 5G cellular band is separated from the radio altimeter band, the Rockwell-Collins systems were receiving occasional interference from ground antennas during landing. Since the initial issue was discovered, they’ve patched the transceivers with better filtering (supposedly from just adding a LPF filter, which wasn’t necessary before); and issued a service bulletin requiring the use of a newer model of antenna (which used to be optional. The 5 fleets I work on have all been updated or verified at this point.

It doesn’t. They just don’t want you distracted during takeoff or landing.

Cell phones are on a completely different frequency band from any navigation systems on an aircraft. They do not cause interference. The only exception would be if you went all the way up into the flight deck and laid your cell phone right next to the magnetic standby compass (which they absolutely are not using).

The primary reason is a combination of safety during takeoff and landing (they don’t want anyone distracted during these critical moments of flight); and years of federal regulation that will probably never be updated until the generational gap works its way through the FAA, or some sort of reform occurs.

Or go in with a lot of money you’re willing to lose for no guaranteed payout

You’re back in boot county once you escape the metropolis.

The only thing Red Wings has kept up on for quality is their hand-stiched boots, and they made them much more expensive than they used to be. What used to last 10+ years before needing repair; now only lasts about a year and can’t be repaired. It’s sad, because the leather is still good on my boots, but the soles are completely worn out and almost bald.

HTC, Valve, and Oculus (well before the Facebook buyout) established very early on that frame rates of 90 fps or higher with a response time of <1 ms were critical factors for preventing motion sickness. Meta either hasn’t gotten the memo or just doesn’t care.

Even with well-established VR legs, I start feeling unpleasant if my FPS starts dropping below 75 for extended periods of time.

Aside from that, it’s also down to game development. I’ve been seeing newer, inexperienced VR developers creating scenes that don’t take into consideration how our brains perceive motion; and they end up creating some nausea-inducing scenes or game mechanics, in addition to doing things like shoving your head onto the floor or through an object. The easiest example is pressing into a wall or table, and the colliders shove your head and body back when you’re not expecting it.
