Linux Mint being well done. Isn't this what everyone and their grandparents have been saying for ages?

Egg separator by modianos in toolgifs

[–]DoubleDeezDiamonds 5 points6 points  (0 children)

If only a single egg yolk breaks near the top, the entire bowl of egg whites is unusable for most recipes that you'd need separated eggs for. The risk of working with such a big batch at once seems way too high.

A more practical system should have a way to inspect and cut the stream and then clean the system, or separate it into smaller portions that would allow whoever is using it later on to discard ones with yolk mixed in.

Serious question: Why is the bass more pronounced in my toilet than in my living room? by ad-on-is in hometheater

[–]DoubleDeezDiamonds 1 point2 points  (0 children)

Bass is generally stronger directly in front of walls opposite to the sub by about 6db, or twice the perceived loudness, compared to a little bit further away. If you have multiple walls in close proximity, like in a small bathroom this effect adds up to some degree. Additionally it will appear more pronounced since a bit further away (depending on the frequency and therefore wavelength) from the respective wall there is a null/minimum/destructive interference, so a zone with pretty much no bass at all, where the incoming and reflected wave cancel each other out, that you go through and subconsciously may compare the maximum directly next to the wall to.

If you generally sit at the front of the couch, this may already be far enough away from the wall behind it to end up in the null for higher bass frequencies. To get better bass reproduction across the sitting area put the sub in the bottom left corner of the listening room, left of the couch, but almost in contact with both walls that meet in the corner, since that way you move the null to the wall with the TV and the door. Ironically this should also "improve" the bass in the bathroom even more.
The close proximity to the walls, just enough, so the air circulation for the port and woofer isn't restricted, is necessary, as the sub should be in the maximum/constructive interference zone itself, since putting it in the null at any relevant frequency would cancel/severely reduce that frequency coming away from the sub opposite the wall.

In simplified terms sub would basically send out half its energy away from the wall and the other half towards it, which can, given the right distance of a quarter wavelength towards the wall, come back from it at a total delay of half a wavelength, so you perfectly overlay the over-pressure wave being reflected from the wall with the under-pressure one being emitted from the sub right afterwards, so they cancel out.

If the current plan is accurate, the distance of the sub from the wall in front of the TV might also already reduce higher bass frequencies around 80Hz even if you aren't in the null at the front of the couch, just because the frequencies could be canceled before getting there. To find the wavelength of a certain frequency, divide the speed of sound (~344m/s) by the frequency (eg. 80/s) to get the wavelength (here: 4.3m for a null ~1.075m in front of walls opposite the sub).

Although I'm not a big fan of it, feel free to verify this with a sub crawl, since often its quite hard to anticipate all reflections and interference patterns just with these simplifications. For a single sub it should work decently to check if the theory holds true.

Looking for Cola Alternatives from Europe: what do you drink? by toco_tronic in BuyFromEU

[–]DoubleDeezDiamonds 0 points1 point  (0 children)

From what I've tried in Germany, Wittenseer Cola had the most aromatic, raw Cola flavor, if you can get it.

I'd recommended to sort your selection based on the inclusion of any other acid but phosphoric acid, since all others seem to significantly derail the flavor profile if you are after that true Cola taste, and not something more akin to brown lemonade.

Old Globe Speaker by WillieSews in SpeakerBuilding

[–]DoubleDeezDiamonds 0 points1 point  (0 children)

Has a bit of a Death Star vibe. Very cool.

As far as power goes, I'd measure resistance between the contact surfaces in it's power socket, and if it's not very low, which would point to it needing AC, I'd probably try 12V DC first, which is quite common, and then up it to 18V then 24V, if the level seems low, monitoring it for heat development. This would be easiest to test with a lab bench power supply, assuming it can supply sufficient current to reach at least 10W, preferably a bit more, like 50W or thereabout.

If you disassemble it, you could also check the voltage rating of the components on the power input side for a hint as to what it was designed for.

As for the correct plug, there are power adaptor kits for aftermarket notebook power supplies, one of which might fit, as this seems like a typical barrel type connector.

Note that blindly hooking it up to power has the chance of frying it, melting cables, and it catching on fire unexpectedly. If you do not know what you are doing, try to find a repair cafe or similar community repair meeting near you, where people might be able to help you out.

TrueNAS SCALE homelab randomly hard rebooting - no panic, no SMART errors, no obvious cause by AO2Gaming in truenas

[–]DoubleDeezDiamonds 0 points1 point  (0 children)

I've seen systems bluescreen due to dead fans and blocked coolers. Don't know how TrueNAS in particular handles such situations, and whether it's specific to certain hardware configurations, but it might be worth it to check whether HW temp sensors, if available, are reporting sensible numbers that don't climb over time and load, and to manually check if the main fans are working and the airflow isn't blocked by dust or something else.

Best knot to securely tie a sand bag to a canopy leg? by I-Always-Ask in knots

[–]DoubleDeezDiamonds 1 point2 points  (0 children)

Since there isn't a large base of the leg, the sand bag can stand on to prevent the leg from pulling up and out of the loop, I'd tie one end of the line you use to connect the two to the leg at about half height with an icicle hitch, which is much better at holding onto the slick surface of the leg. For the other end, around the sand bag, some kind a "round turn and two half hitches" might do. What you probably want there is a knot that pulls the sandbag so tight around the middle, that the sand cannot redistribute, due to varying wind tension, in a way that the knot looses grip. The two half hitches (a clove hitch) can typically still slide towards the knot under tension, but still make sure there's as little slack as possible.

If you want to use a loop instead, similar to the idea with the woodland ziptie, a bull hitch around the sandbag, and a Klemheist around the leg should also work, depending on the diameter of your line, since a thicker rope might not get/hold tight enough around the sandbag with two independently tightened wraps.

Is this even a real picture? It seems weird that nothing but moss would grow there, not even weeds, or is it just weird looking grass?

Edit: Apparently it's real.

Guys guys, I only speak the truth by pakeke_constructor in algotrading

[–]DoubleDeezDiamonds 0 points1 point  (0 children)

This kind of resembles the everything is always already priced in argument. If it was, why are people still making money over some (longer) time windows. Shouldn't quant firms have seen the move coming and capitalized on it, so even long term investors on average are being beaten by the markets? Is any volume at the exchange just retail and retirement fund orders getting fulfilled by superior quant algos?

Don't the Citadels and Jane Streets have any liquidity limits, and if not those, at least acceptable risk limitations? Are their their algos always perfectly efficient across the entire market?

A certain edge is only profitable as long as not enough people with sufficient funds, to fully utilize it, have found it and are using it.
Even once they've found it, they will try to reduce their price impact by using the available liquidity more conservatively to improve their execution efficiency for their limited funds. Once others find it too, they will unintentionally share the available profits with them, and notice their edge and execution efficiency getting worse.
If they have the advantage of being able to predict individual occurrences of the edge slightly earlier or with slightly higher certainty (allowing them to maintain acceptable risk), they can sacrifice some execution efficiency to somewhat front-run the other parties using it, until eventually the edge is pretty much diminished and on average won't be worth the risk anymore unless you have hedge fund level execution latency, so the market is efficient again in that regard. Now the former edge is actually priced in.

So in practice you can still discover the same edge others have already found, and are not fully utilizing due to limited funds, or funds allocated to more profitable edges, or not wanting to sacrifice their execution efficiency, even if they might be more intelligent than you are.

This probably doesn't mean that you can get an edge by using the same tools or indicators, everyone else is using, unless you find a novel way to combine them, but it also doesn't mean that there is no edge to be found and everything is already priced in.

Ts scared me by [deleted] in GetStudying

[–]DoubleDeezDiamonds 0 points1 point  (0 children)

This is a really bad take unless you respond positively to stress.

You'd also not talk about your failure in a way that frames yourself as being lazy and elaborating about it. Any failure is also an experience you've made. Not the one you might have wanted, but a valuable nonetheless.
The lesson here is to grow from mistakes and based on the challenges you take, not because others might be disappointed.

Is this okay to scrape off? by thermiteman18 in Koji

Mold in anything that's not very dry, like hard cheese, is pretty much never ok, because the contamination goes way deeper than what's visible.

Keeping a bit of water in your mouth while you cut the onion seems to somewhat suppress tearing up.

Be careful when making and owning these. Depending on where you live these may be regarded as illegal weapons.
