@realEstateTrent @RestaurantWill Was the only one around for a bit. When they decided to add another nearby, they first sent people from corporate to our annual HOA meeting to pitch it. Community wasn't thrilled with the planned site, but we suggested another site in the same plaza. They took our suggestion.

@RestaurantWill @realEstateTrent The Chick-fil-A in Springfield, VA is in-line. It's chaotic. You order in the back alley and exit through a gap in the middle.

@noelness Minions, Encanto, and Moana over here.

@GazEtc @osb_mc @TheRealMattDowd Without commenting on any particular case: MPEP 2144.04(I) & 2144.04(IV)(B) come to mind.

@MagnumIP Right, my point is when examiners let ODP be held in abeyance, they often need to keep applying the ODP rejection after each amendment. If applicant can hold issue in abeyance, examiners should be able to as well. I.e. put on notice that issue will not be considered new grounds.

[Richard K Durden @RKDurden]

@MagnumIP In this scenario, if it's the only remaining issue in a case after the response to non-final and applicant hasn't filed a TD, can the next ODP-only action be made final?

@PerErikKarlsson @rocketrepreneur @lougrims @GeorgeWHerbert @joebarnard @SciGuySpace I'm not sure I follow. You don't release the vehicle from the circular system after one revolution. You spin it up like a centrifuge, accelerating until you reach the desired velocity, then release it.

[Richard K Durden @RKDurden]

@PerErikKarlsson @rocketrepreneur @lougrims @GeorgeWHerbert @joebarnard @SciGuySpace With a circular launch system, you can add energy (i.e. spin up) gradually at essentially the same location. For a linear system, you only have the length of your "barrel" to add energy, so you need to accelerate fast or have a very, very long system.

[Richard K Durden @RKDurden]

@rocketrepreneur @GeorgeWHerbert @joebarnard @SciGuySpace I'm sure it's been thoroughly considered by their team, but g-forces on payload during spin-up appear to be primarily lateral rather than axial. It would seem to require very different reinforcement solutions, and optimization likely introduces an interesting bit of asymmetry.

@joebarnard @SciGuySpace Consider: Project West Ford but SpinLaunched™.

@MLSist Many companies have "first move forward" policies, so your first move when starting a new drive must be forward. It's a safety rule backed by data. I picked up the habit from a previous job when it was required and it just stuck.

@Raspberry__Rose @sh44sti This is very similar to the plot of Beforeigners on HBO Nordic. Was recently removed from HBO Max, unfortunately.

@dbrand any plans for a something skin for Pixel 6a? (It's not available as an option in the suggestion drop-down).

[Richard K Durden @RKDurden]

@GeraintHarrison @Chopchop_tft @PatentMemes @GazEtc I guess that's the only way to separate the normal pigs from the abnormal ones, intelligently.

[Richard K Durden @RKDurden]

@PatentMemes @GazEtc An accelerometer? I'm assuming this is meant to be interpreted as "acquire an instantaneous acceleration value", etc.

A wild @RKDurden appears! Ligado's fight for the L-band heats up. Also, OSIRIS-APEx, SOFIA's end, and a Dragon conveyor belt. https://t.co/mhbk9oulan

@ericbusboom @ericpeebles @wlfpir8 @NanoRaptor @AndrewMontagne I've coincidentally read a lot about self-tapping screw design recently. The leading tip area without threads will drill, and then the first part of the threads where the flute extends will tap, before the full threads engage normally.

@sciencepolicia @MrFresh You can get a glass / ceramic / tile drill bit and probably make a much cleaner drain hole. Use water as a lubricant and take it slow.

@lars_0 Amazon lockers are similar coded with unique names. One near me is named after a relatively obscure clothing item.

@cragbot1 My professors would occasionally give us incredibly cursed mixed unit problems, on purpose.
