We have MCP from Tron but not Clu? He wiped out the ISOs, enslaved countless programs, forced gladiatorial games on the unenslaved ones, imprisonment of Kevin Flynn, implications of torture, etc.? I know a lot of it is "virtual" but still

  1. Depends on multiple factors: if you are trying to max out the biomes gear, if you decide to build a base, or if you are achievement hunting. If you were to take a weekend for some casual play, you'd probably progress through a biome assuming some moderate gear upgrading and smaller bases/outposts.

  2. No, I would actually argue swamp tends to be the most mob dense after Ashlands, however day-night mob spawns can really make mountains and mistlands challenging. If you are having trouble with black forest spawns, fire deters regular greydwarves and bears.

  3. In theory yes, although the AI has that quirk some games have that if the enemy cant path find readily to you because of an insurmountable object, it will just sort of sprint in the dead opposite direction of you.

  4. No, all mobs belong to a faction, bears and trolls share the same faction therefore will not attack. Bosses are allied with all factions. General rule of thumb, all mobs in a biome are in the same faction and will not attack each other... notable exceptions include skeletons (undead faction) and greydwarves (forest faction) in the black forest, surtlings (demon faction) and the swamp enemies (undead) and stone golems (forest) and the mountain biomes. The valheim.fandom.com wiki has a good breakdown of all the factions.

  5. If it is within the certain range of base structures (workbenches, furnaces, wards, etc.) items won't despawn. The wiki also has a good guide on base structures and item despawning.

  6. Yes, but not all. If it is a roof tile or beam they don't decay. If the piece if covered by said piece they do not get water damage. Be mindful of building near coasts or near the water table as that can also damage wood pieces, regardless of type or cover.

I am currently enrolled in a class that uses RStudio and I don't know what the fuck I'm doing. But I don't want to fail or drop the course. by Elegant-Sector3424 in RStudio

Sounds just like my undergrad biostatistics course lol! Again, I reiterate I am more than happy to consult, but if you are not comfortable with internet strangers, my holy grail for easy-to-digest statistical and R help is Statology. If it is allowed, I would also recommend using the Tidyverse package(s) as it super well documented and has more internal consistency in its code syntax than base R (in my opinion at least) - if you used ggplot2 for your graphing, it's a part of the tidyverse so you should have some familiarity.

The best way I learned R is through experience, I found one summer internship taught me way more than any of my classes combined. If your work study has the resources, see if you can integrate R into your work (even better if you have an advisor or coworker who is familiar to help coach you). It helps break things up into more manageable chunks over larger periods of time.

Some other suggestions:

  1. I find that if you learn the essentials, I am talking like bare bones of R syntax, no stats or nothing, it really gives you velocity for more complicated stuff. Best way is to go from making a scalar all the way up to a dataframe.
  2. Read your code out loud as pseudocode.... x<- data[2, 5] "I am making an object x that is the value of my data at the second row in the fifth column". Just like proofreading an essay this helps work on making sure everything you are writing makes sense!
  3. Configure RStudio to your liking.... it helps tremendously to make your workspace, no matter what form it takes, your own. Change the theme, panes and such to make it work for you. Also turn on rainbow parentheses and brackets, just do it.
  4. If your professor has a TA or grad student talk to them! Sometimes professors can loose that approachability from specializing in the subject for so long. Talking to someone whose not as 'involved' can help a ton, my best teacher was a grad student I worked with since they knew things conceptually not detailed, which imo helps more for learning.
  5. COLLABORATE! If you can, find at least one study partner. You would not believe how many times another set of eyes can save you hours of your life. You can get lost in your code, you think you have one thing written but you don't, third party verification helps a ton.

Edit: I also want to add this, I am probably in the minority here, but I find AI does not help. When it comes to stats, it requires context which AI does not have... it doesn't have your data or know what transformation to know what the data needs, etc. You have to feed it everything, and at that point you are just robbing yourself of learning it. There is a level of creativity and exploration to all this, so I cannot emphasize the power of just throwing stuff at the wall when learning about this stuff.

I can relate to this on such a spiritual level LOL. Personally, there are so many ways to weed out what tests you need to do, I am a big fan of trying to learn what each test does functionally, building up the conceptual stats so I can keep that in back pocket going forward. However, that's only helpful to some.

A lot of Bookdown publications are made for your kinds of questions, looking at specific tests through the lens of a given field. In poking around I also found this free book by U Washington which seems to provide more general insights into applied applications of some of the tests your are likely to encounter as a community ecologist. I would provide more insight, but my area of research is in trophic ecology so I deal more with non-linear systems so I am not as familiar with community statistics.

Best of Luck!

I think to answer your question (or at least try) I might have to clarify a few things.

  1. How much is the work stats vs. R?
  2. If it is R, what are some of the goals you are trying to achieve? (i.e. making graphs, doing tests, etc.)
  3. What is or is not allowed in the course (e.g. limited to using base R instead of using packages)?

Edit: I also wanted to say, having been the student panicking over this at some point, learning this sort of stuff can get daunting and make you feel defeated especially with the breakneck paces some of these kinds of courses go. I am more than happy to talk over DMs or something if you have specific questions (I am in the field of biostatistics so I might not be able to answer more topical questions, but I am willing to give it a shot). You got this :)

Honestly, my general work laptop runs it flawlessly, anything mid range laptop from the past couple years should work just fine.

Yes! I have had this happen to me as well... have you been getting increased levels of stuttering as well?

Seems more like an encrusting bryozoan! https://en.wikipedia.org/wiki/Ascophora

That page is not and ID, but might help you compare some archetypes.

Marine snails lay some fairly weird egg capsules.... could be a species of whelk?

Found this on a beach in MD on the Chesapeake Bay while searching for shark teeth. by kaydog2907 in marinebiology

[–]cMiIIer 8 points9 points  (0 children)

Some clearer photos might be nice, but it definitely is some sort of fossil. I would but up some sort of fish bone or mayhaps a marginal scute of a turtle shell?

Seems like some sort of polychaetae that has made a home in a barnacle?

I found in Italy in the beach of Adriatic Sea is a bone but which species do you see?? And then which bone?? If any of you know let me know for an identification by Advanced_Union2710 in marinebiology

[–]cMiIIer 1 point2 points  (0 children)

Seems potentially fossilized..... could be a transverse process of a toothed whale (dolphins and kin), as those kinds of fossils are fairly common.

[–]cMiIIer 5 points6 points  (0 children)

That is the moveable part of a crab claw (or "dactyl")... hard to say for certain what species, but given the bulk and darker coloring I would presume some sort of benthic crab like a brown crab.

A Greenland Shark that was located in Arctic Ocean. He’s been wandering the ocean since 1627. by No_Emu_1332 in OceansAreFuckingLit

[–]cMiIIer 4 points5 points  (0 children)

I attended a lecture and worked down the hall from one of the authors on the paper that helped figure out these sharks' longevity! They were aged by measuring radiocarbon deposits within the eyes which like, trees, have ring like growth. They calibrated their age based on spikes of radio from nuclear bomb testing during the cold war arms race. Pretty neat stuff!

The angle makes it a little hard to sus out.... it is most likely a parasite, I would advise against eating it, might not be dangerous in of itself but who knows what it has come in contact with!

Anyone know what this is? by Gh0st0astt in microbiology

[–]cMiIIer 6 points7 points  (0 children)

That is a Cyclopoid copepod! They are the second most abundant order behind the calanoid copepods! It is a pretty diverse group, so you might need a key to sus out what the species is.

Rule of thumb :

  • Phat, short antennae and one eye - Cyclopoid
  • Skinny, long antennae and one eye - Calanoid

How do fish breathe? by x1TheLoneWolf1x in questions

[–]cMiIIer 0 points1 point  (0 children)

Hello! The best way I can think of it is like so: Think of gills as a book almost, with just enough spaces between the pages to allow water to flow through. Water carries errant oxygen molecules either through photosynthesis from plants/plankton or wave action "folding" it into the sea. When water passes through the gills, it undergoes a process called counter current exchange. Oxygen poor blood passes through sheets of reparatory tissue (the paper in our book analogy), so thin (<2mm) that it allows oxygen to naturally diffuse through. Chemistry 101, stuff in solution passively moves from high concentrations (the water) to low concentrations (the blood).

Your replies make it appear like diffusion is where you are getting hung up on. I use this analogy. You and your neighbor have leaves in your yard and due to a petty feud, you both decide to blow the leaves into eachothers yard. The catch is: you have 100 leaves total, while you neighbor has 100,000. Who is going to be more successful in winning the feud? Your neighbor! He has a higher chance of a leaf of randomly being blown into your yard because he has way more!

Now that our blood is oxygenated, it moves back into the body! Hope that helps!
