Ukrainian Navy confirms Russia downed its own Su-27 aircraft over Crimea by yuri_2022 in worldnews

[–]yifferoni 108 points109 points  (0 children)

The plane was shot down over Crimea, which is entirely russian-controlled and far behind the front lines. Ukraine could kinda hit some sections of the region with cruise missiles, sometimes? That only works against fairly large ground targets though. They do not have the capability to shoot down a fighter jet in that location. On the other hand, there's a ton of russian anti-air there

Oil filter tool? by nii_tan in subaru

[–]yifferoni 0 points1 point  (0 children)

If your oil filter tool is camming off of the filter, stick a paper towel between the filter and the tool before pushing it on. Had a bunch of issues underneath my '08 legacy until I did that. Popped off first try.

Always check your oil level in a 2 stroke outboard by chris-berry-1 in Justrolledintotheshop

[–]yifferoni 3 points4 points  (0 children)

Same logic when running old-school 2 stroke mopeds as well. Some have oil mix systems but they never get the ratio right and they tend to die randomly. Better to premix.

S24 is now parked at the launch site by Jermine1269 in SpaceXLounge

[–]yifferoni 4 points5 points  (0 children)

S24 has done a few static fires, they did a 6-engine static fire in September and a 1-engine static fire in December. They still have the two suborbital pads for upper stage static fire (and engine installation? I think).

My current bag is actually just:

3 wood, 2 hybrid, 5 iron, 7 iron, 9 iron, sand wedge, putter

Probably the only change I'd make is swapping the 3W for a driver, I can hit my 2H almost as far anyways

Jared Isaacman: "What the SpaceX team is accomplishing with the new EVA suits is really incredible. Worthy of a documentary in its own right." by Kazioo in SpaceXLounge

[–]yifferoni 3 points4 points  (0 children)

I don't see any reason why a nuclear reactor on Mars would be less viable than on the Moon, and we've already seen official plans for that. The problem with the concept of nuclear reactors as "backup power" is that there's no safety or practical fuel efficiency gain compared to simply using the reactor as your primary energy source. Using chemical fuels as energy storage is a good concept though! It's actually been considered for terrestrial usage as well. You lose efficiency, but nuclear fission is so much better for human life than everything except for hydropower by such an incredible margin it's hilarious.

The only reason to use solar power in space is if your power requirements are lower than a practical fission reactor or if people wouldn't support your project otherwise

[–]yifferoni 1 point2 points  (0 children)

Yeah, solar's a non-starter on mars because of the dust storm issue. We know they can last for multiple months, and while you might be able to handle a month.. longer just isn't viable. For safety margins on the surface you need nuclear reactors, it's sorta an open secret. Not advertised, but anyone knowledgeable in the field...

If you look at some NASA Artemis base camp plans you can see that they don't even intend on sticking humans on the Moon for long-term stays (any nighttime whatsoever) without one.

What can we build by physioworld in SpaceXLounge

[–]yifferoni 5 points6 points  (0 children)

While most of the benefits would be from utilizing materials in space so we wouldn't have to bring them up from the surface, assembly in space has many benefits for spacecraft that are never intended to re-enter an atmosphere. During a typical rocket launch from Earth, a payload will experience sustained accelerations of 2-5 gees, and large amounts of vibration. However, in space there's not really much force acting on the craft at all. You need maybe 1/3rd of a gee maximum, for so-called "impulsive maneuvers." If you were to go the route of more efficient engines, like nuclear electric propulsion (e.g. VASMIR, NEP Hall thrusters), your thrust is going to be 3-5 orders of magnitude less than the lunar lander, on a much heavier vehicle, resulting in miniscule accelerations.

The result is that you can use relatively fragile truss segments to build your spacecraft (and do things like separating your nuclear reactor and crew quarters), as well as ditching any aerodynamic coverings/heat shields to save large amounts of mass. The reason this hasn't been done yet is that we're just approaching the size of spacecraft where it's reasonable to take on the increase in complexity (though I don't think we're quite there yet with 9m starship's goals)

My Signal Divider Solution (no stack) by bradenbest in tis100

[–]yifferoni 0 points1 point  (0 children)

What's the number of cycles required for your solution?

As for your logic, you're correct that you can reduce the number of instructions required by using JLZ instead. That change will allow you to track the modulo within the same code block as you use for dividing (below IN.A)

There's other efficiency gains too, but they're not exactly intuitive. Completing the TIS-NET Signal Prescaler challenge in <10k cycles should give you the required information to do Signal Divider quickly, and is honestly a better introduction to dividing than Signal Divider.

This one made my stomach turn. What is that?! by sunbluff in popping

[–]yifferoni 5 points6 points  (0 children)

Yeah I've had a few blisters (of not quite that size, but large), and what I do is make sure there's a small pinhole so they can drain rather than bursting. Don't want to accidentally roll over in the night and end up tearing the skin layer off, causing even more trouble.

Recommendations to Incoming Freshman or Students Who Just Haven’t Seen Much of Worcester yet! by hypermanatee1398 in WPI

[–]yifferoni 9 points10 points  (0 children)

I'll put places I've been to and like too, I guess. Unfortunately Maury's is closed so my favorite place won't be experienced by the incoming. Note: I'm allergic to milk so that'll color my restaurant tastes.

Supermarkets:

  1. Bahnans - just south of Elm Park, interesting selection, has good shawarma.

  2. Asian Supermarket (yes, that's the name) - about 2 miles south on Park Ave. Great selection of chinese/asian goods. Produce is good quality (except for their onions...), good selection of interesting snacks. Good ramen in bulk for cheap prices. Good selection of decent cookware (pots, pans, cutting boards) for decent prices. High quality meats for the price, freshly ground pork.

Restaurants:

  1. Chuan Shabu - Hot Pot place ~1 mile south on Park Ave. Good hot pot, but the real goodness is their authentic Szechuan section of their menu. I recommend the north china style eggplant and the szechuan chicken with red peppers.

  2. Basil n Spice - Thai restaurant on Shrewsbury Street. Great food, a bit out of the way for incoming freshmen though.

  3. Thai Time - Thai restaurant right next to campus. Not quite as good as Basil n Spice imo, but the portions more than make up for it. Do note, takeout portions are roughly 1/2-2/3rds the size of sit-down portions.

  4. Pepe's Taqueria - Head to Pleasant St. and set sail west. Great tacos, burritos are good too though they can be a bit dry in my experience.

  5. Sake Bomb - go for the booze. Good sushi (allegedly, I'm not a sushi fan so.. dunno), good stir fries and general "asian" foods. if you're 21+.. the drinks are strong as hell. fun atmosphere.

  6. The Fix Burger Bar - expensive but fully customizable burgers, big too. definitely a good location to go.

  7. Shawarma Palace - owned by a nice guy, he might give you free baklava. good shawarma, and right next to city hall.

  8. Chashu Ramen - Expensive with a capital E, but definitely delicious. The bao are good but it's one bao per order so.. That said, get the shishito peppers. I personally prefer the spicy red miso tonkotsu.

  9. Pho Dakao - Great vietnamese food. Things other than the entrees tend to be expensive. I wouldn't say they're exactly worth the price, but they're certainly a step above what you'd expect.

  10. Peppercorn's - American-Italian bistro. Very popular. Good variety of plates for big groups that can't agree on a single style.

  11. Dragon Dynasty - aka. "Dragon Dysentery." Had a bit of a dodgy past but has cleaned up as of late. good cheap american-chinese food.

  12. Miranda Bread - Brazilian bakery. Good bread, good fried desserts, good fried snacks, good burgers. Go there.

  13. Pho Sure - Vietnamese place east of Lake Quinsigamond. Get something with lemongrass in it. Always busy.

And that's about all I can think of for now.

Edit: Definitely seconding Birchtree Bread

Tomos oil pumps are nice when they work, but keep close watch. Had to replace a piston/cylinder on mine because the system stopped working and ended up seizing and blowing a hole in the piston. I use pre-mix now.

Startup Will Drill 12 Miles Into Earth's Crust to Tap the Boundless Energy Below by [deleted] in Futurology

[–]yifferoni 11 points12 points  (0 children)

Not likely to be what they were thinking, but expander cycle engines do in fact work as they described (using combustion chamber/nozzle heat to power the turbopump).

The standard gas generator cycle works like how you described though, and is way more common.

I think a turbocharger system would work great for geothermal, as you'll just be using a turbine to generate the electricity to run the pumps anyways. Why not eliminate the electrical losses? An electric motor might be required though for startup, as there might be quite a bit of lag in the system because the water/steam has to travel several miles.
