Can anyone comment on the safety of PayPal for personal transactions online? I'm selling a piece of electronics and someone in another city is pretty keen on buying it, and wants to use PP. I've never used it for personal transactions before and I'm a bit worried about being scammed, for example I see the transaction go through and ship the item and then it's cancelled before I can retrieve my funds. is this a thing? Thanks for your time!

Is there any truth to 'dream analysis', or is it hokum? Seems to me to lean heavily on subconscious universal archetypical concepts, which feels a little bit too close to the theories of a certain popular right-wing psychologist for my liking. But IDK much about psychology, maybe it is more commonly accepted that certain themes can exist in our subconscious?

All I know is I feel weird googling "what does ____ in a dream mean," it's maybe me at my most superstitious and I should just drop that.

A recent derail in the Tweets thread (about closed/open-casket funerals) got me thinking about something that I've been curious about for a while.

Does some perfume smell like straight-up formaldehyde to you?

Four years ago my Dad passed away and it's the only time in recent memory I've been to a funeral. The service was nice, of course the whole thing sucked but the thing that stuck with me most was the scent of the funeral home, of the preparation, which I assume must be formaldehyde. It had a vinegary smell but a lot more pungent than simple vinegar. And it lingered with me; I felt like I was still smelling it days later. Really unsettling stuff.

Since then, every once in a while someone will pass me drenched in some sort of perfume, and it brings back those unpleasant pungent memories because it smells exactly the same. Not even masked by anything pleasant like you'd expect a perfume to smell like, just straight-up formaldehyde.

I've mentioned this to some friends and they think I'm crazy. So a part of me feels like it might be some weird phenomenon like how certain people find the taste of cilantro revolting. Is this possible? Am I crazy? Or does some perfume legitimately just smell offensively terrible?

How sure are you that that smell was the formaldehyde? Seems like a funeral home may have been using perfume to cover it and other smells up.

It's possible, but if so it was the worst perfume I've ever smelled. Absolutely nauseating, and like I said it seemed to stick in my sinuses for like a week afterwards. Of course maybe that's more about the trauma of burying a family member.

Let's talk about gasoline.

Why is it stored underground and pumped up, instead of in raised tanks or even at ground level? I'm guessing it's because it's less of a fire risk, less subject to temperature fluctuations in general, if it's stored underground.

How long does gas last before it turns into varnish? Do gasoline companies put stabilizer into tanks at gas stations like you would in the tank of a motorcycle being stored for the winter? What if (as if) demand disappeared tomorrow, how long would the gas at a station remain stable? What about the opposite, how often during shortages do gas stations run out of fuel?

What about octane rating - I know what it does and why it's needed only in high-compression engines, but is each octane stored in a discrete tank? Or is there some sort of chemical mixing/dilution going on when you select 89 over 93?

How hard is gasoline to synthesize? I mean, is it possible to create in a lab, instead of extracting it from oil? Someone long ago said that gas "is basically the perfect fuel," in terms of its energy density, its portability, its relative safety and how quickly you can fill up. I think about that a lot.

I was thinking a bit about video games that feature real-world locations, like how the new Overwatch apparently has 22 maps inspired by real cities including Toronto. I don't play Overwatch but I can think of handfuls of games that either feature or very obviously imitate real-world locales.

Do the game designers send their graphics team on business trips to document these places and ensure that their recreations of them are faithful? I'd have to imagine they do. What a sweet gig, getting an expenses-paid trip to somewhere like Prague to work on Deus Ex, or really, any of the locations featured in Far Cry games.

This guy on twitter is eating a whole rotisserie chicken every day. He's up to 39 days and showing no signs of stopping. I'm curious about this because it honestly doesn't seem like that much food - when I was bodybuilding, I would have loved to do that for at least a few weeks. But I wonder how long you could keep that up, would your body start rejecting it after a period or would you adapt and instead get sick if you changed your diet? Assuming you're also eating other things like vegetables.

It got some friends talking about "if you could eat just one thing for a year/the rest of your life/whatever, what would it be?" I think I'd pick salmon sushi. Also not really all that bad for you if you're active, but again I wonder about the cumulative effect - we know that seafood tends to have a bit of mercury in it, could you actually get mercury poisoning from eating a great deal of salmon over an extended period of time, is that even possible? Or conversely, could you get acute mercury poisoning from eating a ton of salmon in one sitting? Is THAT even possible?

This is all fascinating stuff, thanks. Further to it - and I feel like I asked this somewhere else in the forums recently but can't remember where - aren't there certain communities, I'm thinking mostly of the Inuit, who are actually adapted to the particular offal diets? Like BonHair brought up already, you can't eat the liver of certain animals because of vitamin poisoning - but I thought I read somewhere that this isn't necessarily true for Inuit communities that subsist on that sort of thing. Am I imagining things, or is there any truth to that?

Medical question:

Hypothetically, what is 'more immediately lethal'; a severed carotid, or a severed jugular? I would think the carotid is worse because it supplies blood to the brain, but is there a meaningful difference? A friend and I were just talking about the time an NHL goaltender's jugular was accidentally slashed by a player's skate, and IIRC someone said his life was saved by the team medic immediately going out to clamp down on the vein. It got me curious about whether it would have been a different story with the carotid severed.

I'm thinking primarily of the famous portrait of General Sherman but I'm pretty sure there are other examples as well.

I'm having some trouble sharing a spreadsheet I've created. It's a playlist from my DJ software that I've cut some extraneous rows out of. The software exports the playlist as an HTML file, and Finder sees it appropriately. I open it up in Excel and it also looks right, so I edit out the unnecessary columns. I save it as an HTM file (not sure what the difference is but this is what Excel wants to do) and it still looks fine in Finder.

But when I upload it to Drive, things get weird. Opening it within Drive yields a bunch of raw HTML code, and downloading it yields an apparently blank document. EDIT: I get basically the same results with DropBox.

Can anyone help me out with this? Ideally, I'd like to get it out in raw text so that I can share it in the body of a post here in the DJ Thread, or in another thread on Reddit.

Not sure if there's a 'small medical questions' thread that this question would be more appropriate for (I skimmed The Goon Doctor a bit and didn't see one), so here goes.

Is a semi-blocked nostril a more serious problem than it sounds? Many years ago I had my nose broken, and while doctors re-broke it in the hospital to set it properly, the cast fell off and I don't think it really ever healed properly. To this day my right nostril feels a bit blocked, not completely but it is uncomfortable, and if I close the other nostril and try to breathe only through the right one, it's definitely more laboured than the inverse.

I've been going through some various medical examinations in the past year for depression, fatigue and some other things. They made me do a sleep study, and while it wasn't really what we were looking for, apparently I have 'mild' sleep apnea. I've been wondering if the nostril thing is a factor.

There's a discussion in the Schad Thread about buying old GPUs from defunct Bitcoin miners and it got me curious. I don't know much about computers except for what I needed to know to juice up my Mac as an audio (and occasional video) editing machine.

Why do we use GPUs for graphics rendering? Why is it a discrete piece of hardware separate from the rest of the motherboard? I've asked this vaguely before and closest thing to a response I got was "turns out GPUs are better for processing video than CPUs," but I don't really know why. Why don't we see other components made out to be so important? I mean, as someone who works with audio I'm familiar with 'external soundcards' (audio interfaces) being a thing, some of the more heavy-duty professional-tier stuff actually does come in the form of a PCI card, but it's my understanding that the bulk of the work is still being handled by the CPU. Is there a historical reason in the industry that video cards are such a big thing?

I feel like there's a good video primer to watch on this stuff but I wouldn't know where to start.

I've been reading and watching some pop science videos about mathematics lately, not sure why because it's always been a weak subject for me - barely having passed in highschool and not giving a poo poo at the time - but I do find it fascinating.

Specifically, I've been wanting to learn more about the Fourier Transform, maybe one of if not the most elegant and revolutionary equations ever devised. That's the good thing about some of these videos; the way they teach and use visual aids is something I never knew, and the math still loses me sometimes but the way it's presented is still relatable.

But I'm stuck on something with wrapping my head around Integrals. One or two of the videos I've watched, and rewound, and watched again, imply to me that measuring the area under a curve is essentially a matter of quantization: You're drawing a bunch of rectangles with heights averaged along the curve (I'm probably butchering the lexicon here, sorry, bear with me), so no matter how many times you subdivide things you're still effectively estimating to some degree - like audiophile nuts say, 'staircases instead of waves', but as ridiculous as that is in an audio context, I thought the purity of absolute mathematics would require some much higher degree of precision. Does this quantization mean we can't actually estimate the exact area of a circle, or under a curve?

I guess where I'm lost is that so many of these videos that talk about measuring a frequency spectrum to extract all of the harmonics from a signal, I can't really wrap my head around how many 'slices' of a complex waveform are being taken, is it infinite? How does the integral function work?

Again I apologize for my layman's nomenclature here.

Is there a utility out there to extract text from .m3u/.m3u8 playlist files? Every time I make a new DJ mix I've been writing out the tracklist into an .rtf by hand and I'd like to save a little bit of time on that.

There is a workaround I can think of but it's clunky: Re-importing the playlist into Traktor from Rekordbox. Traktor allows you to spit out playlists as... .html files, I think, and you can extract the plain text from there. But for some reason Traktor takes ages to open on my machine, and I'd rather not end up with a convoluted mess of playlists in a software I only use for rapid track cataloguing anyway.

If there's a piece of software that can take the .m3u plists and turn them directly into text that'd be dope.

Forgive me, I'm not very familiar with using Terminal. I can drag and drop the .m3u8 file into this prompt, right? Like, type up to '{print $NF}' then drop the file in so I don't have to type out its full path? And then just create a 'tracklist.txt' at the end of the prompt?

The first one is perfect! I'm only looking for 'ARTIST - TRACK TITLE' format as that's the way I've been writing them out by hand up to now. The '4A' etc. is Camelot Wheel notation for mixing harmonically, and so it's baked into the 'track title' field; if there's no way to remove this that's fine.

I tried going back into Traktor and spitting out the plist as .html, last time I was trying to do this I used some sort of HTML to CSV converter in order to post the plist here on SA and in a Reddit post. It mostly works, although as I said having to go back into Traktor is a mote irritating, and I still haven't found a way to turn these tables (lol) into plain text that retains its format.

The below is completely untested but it should, theoretically, work.

code:
awk -F, '/#EXTINF/ { split($2,x,'-'); print x[1], "-", x[3]; }' whatever.m3u8
What it should be doing is treating every line as a csv (-F,) , looking for lines that contain #EXTINF, then taking advantage of the fact that your software appears to be generating #EXTINF:number,Artist - Mixthing - Track uniformly so that it can just take the second field (remember we are separating fields by commas), split the second field into an array by using "-" as separators, and the artist and track are then always the 1st and 3rd items in the array (awk arrays start from 1).

I tried this in Terminal and it returned some sort of syntax error, maybe I copied it incorrectly?

code:
awk: syntax error at source line 1
 context is
	/#EXTINF/ { >>>  split($2,x,-) <<< 
awk: illegal statement at source line 1

quote:

If it's not doing that, the alternative is to customize the playlist tool. It looks like it's hitting the filenames to get the info because your software isn't generating anything else but #EXTINF. If you download the zip and extract the files, open main.js with TextEdit, you'll see a section of code that looks like this at line 34 or so:

code:
        } else {
          // if no title
          warning.style.display = 'inline-block'
          var filename = song.file.split('.')
          filename.pop()
          filename = filename.toString().split('\\').pop().split('/').pop().replace('_', ' ')
          filename = filename.trim()
          result += filename
        }
replace the result += filename line above with this code:

code:
	var fa = filename.split('\-')
	var la = fa[0].split(' ')
	result += la[1].trim() + ' - ' + fa[2].trim()
so that that bit looks like:

code:
        } else {
          // if no title
          warning.style.display = 'inline-block'
          var filename = song.file.split('.')
          filename.pop()
          filename = filename.toString().split('\\').pop().split('/').pop().replace('_', ' ')
          filename = filename.trim()
		  var fa = filename.split('\-')
		  var la = fa[0].split(' ')
		  result += la[1].trim() + ' - ' + fa[2].trim()
        }
Save over the existing main.js and open index.html - if Safari doesn't do right you might have to use Chrome or similar.

While we're on old games, I've been thinking about an old space game I used to play on a buddy's Macintosh Plus. It was two-dimensional, and black&white. Your spaceship would fly around the field avoiding different types of enemies and collecting crystals, and when you collected all of them a 'gate' would open at one end of the map that you'd travel through to proceed to the next level. I might be conflating another game, but I seem to remember the different enemies had names, and one type was called a 'Husket'.

I feel like I read something online (so therefore it is Fact) that .22s have been used for a lot of assassinations partially because they’re a small enough round that they penetrate the body but don’t have enough energy to exit the body. The bullet stays inside and bounces around and fucks stuff up worse than if it were to just cruise right through.

I have no idea whether or not this is true, or if this is actually why it has been used for assassinations vs. their relative ease of use/availability.

This is almost certainly a myth that was popularized by a Joe Pesci movie (Goodfellas, I think).

What are the medical sensors called that are put on your chest/stomach and look like a coiled telephone cable? I did a sleep study recently and I was thinking of all the sensors they put on me; I've seen these depicted in polygraph/lie detector scenes in movies also. There are usually two coiled cables, one high on your chest and one closer to your waist. Are these heart monitors of some sort, and how do they work?
