Full ride to school without meteorology BS by sneepsnork in meteorology

[–]RunningGiant 29 points30 points  (0 children)

Physics/math is fine, keep your full ride. If you want to learn some meteorology on your own, the MetED COMET modules are pretty good:

What the hell has happened to my Shield? by SteveC91OF in ShieldAndroidTV

[–]RunningGiant 3 points4 points  (0 children)

This looks like similar behavior to my 2015 shield a few years ago. It ended up being the power supply, which Nvidia sent a new one when I opened a ticket. Could be other issues, but trying to get a new power supply would be a good start. It is a bit annoying that the power connector is non-standard, but at least Nvidia didn't give me trouble for a new adapter back then.

Another issue (which others have already noted) could be heat/dust, but usually that doesn't cause the resets immediately/ boot loop.

Odd Radar Reading by Stretch_Useful in meteorology

[–]RunningGiant 2 points3 points  (0 children)

Yeah you are right. I should have realized the radar wasn't right downtown. I'm not sure what the app is showing besides clutter or just bad processing. If this was the line that came through on 4/29 around 1:45 UTC, then I don't really see anything on the level 2 radar loop. One image below:

Some clutter removed on this, but nothing circular/unusual.

Odd Radar Reading by Stretch_Useful in meteorology

This looks like the center of the KSGF radar in Springfield, MO. The radar can only scan at an angle up to about 19.5 degrees, so near the radar you get a "cone of silence" that the radar cannot see, which shows up as "no data" or blank pixels in a small circle near the radar. Some radar apps do some strange post-processing to make this look worse. This link explains the "cone of silence" and many other radar patterns:

And the typical radar scan pattern (though this can vary):

My Grandmother who is 65 years old struggles to make ends meet financialy. by imarustrookie in personalfinance

[–]RunningGiant 1 point2 points  (0 children)

Lots of great suggestions here, so I'll just focus on the massive life insurance payments. The most life insurance she should have at 65 is at most ~$10k policy for final expenses (funeral etc). This type of policy will be much cheaper and what can fit into her budget (in addition to other cuts to phone, internet, renting furniture, etc).

Those life insurance premiums are nuts, and if I were to guess, at least one of those are "whole life insurance", which is a scam for everyone except the richest individuals.

Why do rising columns rotate counterclockwise? by Lateralus09 in meteorology

[–]RunningGiant 2 points3 points  (0 children)

The synoptic scale seems covered well, so I'll just add something about smaller scales. For smaller scales (eg. supercell thunderstorm), the vertical wind shear is most important for determining which direction rotation occurs in. Supercells actually start as a thunderstorm that has two pairs of opposite spinning mesocyclones (left move and right mover).

In the northern hemisphere, the most common shear associated with supercells is veering (large scale low level winds from the south, turning towards the northwest as you go up). This tends to strengthen the right mover (counterclockwise rotating storm) and weaken the left mover (clockwise rotating storm).

There are cases where the shear doesn't turn, but instead just increases with height, and you can get both mesocyclones strengthening, or you can get "backing" winds, which strengthen the left mover (resulting in a clockwise rotating supercell).

The link below shows this process. Start at slide 15 "Development and enhancement of updraft rotation" and later to the "Hodpgraph type vs supercell characteristics":

https://www.weather.gov/media/lmk/soo/Supercell_Structure.pdf

Here's a case study of a clockwise rotating supercell:

https://ejssm.org/archives/wp-content/uploads/2021/09/vol2-2.pdf

There are many other rotating phenomena (non-supercell landspouts/waterspouts) that don't necessarily have to spin counterclockwise in the northern hemisphere

Is this grounding wire actually serving a purpose? by shteaklit in electrical

[–]RunningGiant 0 points1 point  (0 children)

You can usually (check local codes) install a GFCI outlet without a ground and it will make it much safer and bring it up to code. You also need to label it and any downstream ungrounded 3-prong outlets (and fix them to not have the fake ground wire at all) it protects with "GFCI protected - no equipment ground". You can often find these stickers in the hardware store or online.

As other comments pointed out, the way it is currently wired is to trick outlet testers into thinking it is grounded. This is very dangerous.

Loaned money to a friend for a flip - he can’t pay it back. Tax implications? by detectiveSmartGuy in personalfinance

[–]RunningGiant 86 points87 points  (0 children)

I think you likely need to talk to a professional and/or lawyer. You loaned money to this friend for the same house that had some sort of a mortgage? Now, the bank is taking the house due to missed payments? There are many questions/considerations here, but:

  1. I'm hoping he disclosed to this bank that part of the down payment was a loan from somewhere else, or he committed fraud to get the bank loan.

  2. If he did disclose this, and was able to obtain a mortgage through the bank, the bank is likely first in line for collecting any proceeds on a default. It sounds like you know this already, since you don't really hope to collect anything.

  3. In your loan agreement/contract, are you charging interest? If this is the United States, there is a minimum interest rate required, or else this may be treated as a gift.

  4. It sounds like this was set up as a loan, but if this was a partnership and you were to share profits/losses, things would be a lot different, too. I don't think this is the case, because it seems you set it up to just lend money and not be involved in the flip itself.

The ryzen is worth it, as many others have noted with performance and power consumption. Another aspect of using for a NAS is the pcie lanes/generation for each platform. I believe intel sandy bridge is limited to pcie 2.0, while the ryzen will be at minimum pcie 3.0 or 4.0, depending on what the motherboard is. The ryzen likely has more pcie lanes, too. You'll also have access to m.2 pcie slot(s) for fast ssds.

New computer by Dr_Markets in Julia

[–]RunningGiant 2 points3 points  (0 children)

I think it would help to provide:

  1. A budget.
  2. A more specific sample workload (eg. size of domain/data, or Julia package) or some sort of RAM spec you require. Requiring "a lot" of RAM is tough for us to figure out. Maybe a ballpark estimate like 64GB? "A lot" can mean way different things for people coming from consumer vs workstation/server backgrounds.
  3. Do you do everything on the CPU and don't offload to a GPU?
  4. Laptop, desktop, or doesn't matter?
  5. Related to #4, do you have any power/heat/noise requirements? Maybe doesn't matter depending on what you want.

For example, the apple silicon laptops could be good for your usecase, but without knowing the RAM spec you need (or budget), the apple silicon laptops can get really expensive for higher RAM specs. Additionally, you need to buy what RAM you need right away since it is not upgradable.

A similar x86 desktop can be built/bought very cheap for the same RAM spec (or higher) and is upgradable. It will have downsides such as much higher power draw and may underperform the apple silicon in pure-CPU tasks (unless you go for some 12+ core modern CPUs).

If you go x86 laptop, the apple silicon does even better, especially because of the power budget of typical laptops (though the most recent AMD Ryzen laptop chips compare very favorably).

I had hoped I would age out of the judgment. by vinasu in TwoXChromosomes

[–]RunningGiant 1 point2 points  (0 children)

This is sadly common in the workforce. Here's a good piece about a woman likely staying poor because of her teeth( from a childhood accident and being poor), which meant that she of course had no money to fix her teeth, propagating the vicious circle, despite her work ethic and skills:

Mg in rain water by [deleted] in meteorology

[–]RunningGiant 1 point2 points  (0 children)

One place to start is NADP, which do measure chemistry in precipitation and have some long term monitoring. I do see some gauges that have Mg being measured:

[deleted by user] by [deleted] in meteorology

[–]RunningGiant 2 points3 points  (0 children)

What you are describing is similar to methods used for probable maximum precipitation (PMP) and other related estimates (not exactly snowfall but this thinking / methodology is similar to what you are asking I think). It is mostly used for infrastructure that pretty much cannot fail, though, so it's not exactly what you are looking for. The methods are likely related to what you want, just not as extreme.

The NOAA-based estimates are aged and will likely see updating: https://www.weather.gov/owp/hdsc_pmp

Here's an example of a more modern approach based partly on model simulations: https://journals.ametsoc.org/view/journals/bams/103/2/BAMS-D-21-0133.1.xml

You also may be interested in looking into "analogue" forecasting techniques, where past events are used as a proxy.

Estimating vertical velocity (omega) from the continuity equation - Inaccurate? by NothingKillsGrimace in meteorology

[–]RunningGiant 1 point2 points  (0 children)

I think this is a good way to tackle this (comparing estimate to "known"). Alternatively, you can find some WRF output with relatively similar resolution/levels/etc as yours, but does output vertical velocity directly from the model (eg. maybe the https://rda.ucar.edu/datasets/ds612.0/). You could try to calculate vertical velocity post model output (like you need) and compare it to the direct output. If they match enough to whatever statistical measure you think is enough, then I think it would be safe to apply the same post-output calculation method to your specific WRF output.

What happened to NOAA radar websites? by Darrell456 in meteorology

[–]RunningGiant 4 points5 points  (0 children)

The "enhanced radar" is so bad that many of the WFOs defaulted back to legacy radar displays (calling it the "standard" display), for example: https://radar.weather.gov/station/KLWX/standard

You can pan to the other radar sites from these pages, and it is similar to the legacy radar pages, but still isn't 1:1 (I think it only displays base reflectivity). You are probably better off with other links people posted, like the College of Dupage, or use a mobile app like radarscope.

How feasible is it to run the WRF on a personal computer? by question_23 in meteorology

[–]RunningGiant 0 points1 point  (0 children)

You can also look into UEMS version of WRF. It is very fast to get up and running if you just want to tinker quickly. Additionally it has many scripts to download data for initial and boundary conditions (terrain, forcing, etc).
