You should learn at least one new thing every day!

What did you guys learn today?

I learned that the Mason-Dixon (sometimes incorrectly called the Mason-Dixie) line is all the way up here in freaking DELAWARE.

That said, eat it yankees!

It's the line between Maryland and Pennsylvania. The town I grew up in is only a couple miles from it. Though, to be fair, most of Maryland is just a couple miles from it.

I read stuff about some of the original Nordic figures Christians transposed old Mediterranean saints onto to co-opt those traditions.

I discovered a couple of days ago that the English word "loot" is from the Hindi (originally Sanskrit) word for "rob".

Speaking of which.. The Norse word for robbery "rn" - and rn/ran in modern Swedish and Danish respectively - is also the name of Rn (http://en.wikipedia.org/wiki/R%C3%A1n), Goddess of the Sea.

Gee, I wonder how they ended up making that association! :roll:

I had been wondering if zombies were an invention of modern culture, but it turns out they originate from African folklore, like voodoo. According to Wikipedia (http://en.wikipedia.org/wiki/Zombie), people believed you could make someone a zombie by poisoning them with pufferfish toxin and delirium-inducing drugs. If they survived, the near-death experience and dissociated state of mind would cause them to believe they were resurrected from the dead, and act accordingly.

I learned something about Turkish Language today!

Apparently, the English (and German) word "Horde" has its origins in the Turkish "ordu" (which is old-Turkish for army). The same goes for the word caviar (from the Turkish havyar) and yoghurt (yoğurt)

This is correct. It is, however, a popular matter of speculation that the name Dixie is indeed derived from Dixon's name. That's one of several possible origins, though.

Masterpiece, fun fact: Albanian is no longer directly related to any surviving European (or otherwise) language, but borrows heavily from Turkish!

GM, I imagine it's probably different in your industry. This class was for property managers so most of it is in the context of reps who are giving you bids for products/services. Much of the problem arises from the fact that the property manager is acting as an agent for the property owner, so it's not actually "your" money, and that property value is usually based on net income, so if costs increase more than necessary you are actually decreasing the value of the owner's asset (which is a violation of your fiduciary responsibility), and that the majority of costs are passed to the tenants in the form of rent, so when they increase without an actual increase in services, it makes the property a less attractive place to lease, which reduces income because you can't get/keep tenants, which again hurts the NOI and property value. SO if you are taking a higher bid price and receiving personal gain, everyone besides you is getting hurt.

And I play poker with a railroad officer.  Since the railroad purchased their right-of-ways (rights-of-way?) they have to provide their own security. 

A large part of his job was people who'd been killed on the tracks.  Some jumpers, too (from the train, not onto it).  Accidents at crossings are joint jurisdictions, but those are a lot less common than deaths out in the middle of nowhere. 

Remember, tunnels and bridges used by high-speed freight trains do not make good shortcuts for hikers!

Oh, you absolutely should do it. I'm just saying that humans are irrational and we're always failing to do things that would take very little effort and get us lots of money!

Today I put into practice a communication model we were taught yesterday. It's called SBAR: Situation, Background, Assessment and Recommendation. I think it's used all over the place but obviously I was learning it in the context of midwifery practice, so mostly for handing over the care of labouring women or making phone calls. This morning I had to ring up my university to give the name and student number of the girl who will be collecting my uniform on my behalf to the woman who distributes the uniforms. Normally I'd be all flustered and anxious about it, but I just used the model and it worked perfectly! Perhaps my Professional and Ethical Practice module isn't entirely boring waffle.

at work I pre-fillout my portion of forms when new employees have to sign paperwork.  At the class the other day I decided to have my backup proctor the class so she could get some experience.  One of the new employees asked where my last name originates from (I have yet to meet anyone outside of family with my last name).  She told them and they said "the way he draws his "1s" look like he's from that part of the world.  Considering my family came to the US 141 years ago I just found out I apparently write like my literate ancestors

Pretty much any model that makes you prepare for a phone call, meeting etc. will make it go better. At a minimum, jot down the things you want to say before you pick up the phone. Best, of course, for any "business" matters is to maintain a log of all your communications, but that's a bit of a counsel of perfection.
Title: Re: Learning has occured
Post by: Carl-E on 25 Oct 2013, 16:02
My mind wanders too far (and fast) for a log of a call to be effective.  Usually info comes and goes too fast to even take decent notes. 

And many of my "business" calls involve a fair amount of vitriol, which doesn't make notetaking any easier...

I learned two things today.
1) In Irish Celtic mythology, the Irish people were descended from the god Donn, which in turn allowed them to kick the asses of the race of gods living in Ireland, making it the only mythology where human defeated the gods.
2) I've started going grey less than a month before my 29th birthday...

Post by: Tulpa on 04 Nov 2013, 02:25
I'd rather be going gray at 29 than balding at 17. Ugh. Now I have a brushed back mohawk which shaves the thinning areas.

Today I learned a lot about implanting things. Bioproofing things is pretty hard to do at home. Bioproofing being coating things in something that is inert and implantable. Like coating magnets to prevent heavy metal poisoning and degradation. Been looking into implanting some magnets into myself if you didn't guess from that.

I'm pretty sure I could take it just fine. Not so sure if I could self perform it, though. I can go into a dissociative trance pretty easily where I don't really feel anything at all. It's a pretty handy ability. But doing it to myself... Probably would be good to be self aware. So I'll have to find someone to do it most likely. Or at least a spotter.

Today, I learned that GameCube discs are smaller than a regular CD. I never had or really hung out with anyone who did, but my roommate has one (along with a Nintendo 64) and he left a game laying around in the common area. My mind was blown.
Title: Re: Learning has occured

That disc size is pretty standard. I remember my first experience with one of them was a couple years before the gamecube came out, I think. Got a computer game on that size disc from some fast food kid's meal when the first x men movie came out which would have made me about six. Now I see them from time to time as driver discs.

Notice that they are (mostly) symmetric (the parthenon thingy is stretching it a bit) and the cutout parts are fairly large...

Penn State's mascot is the Nittany Lion, a breed of mountain lion native to the area (Mount Nitanny is visible from the stadium).  One of the logos they use is the lion's pawprint, which has 5 toes (the only remaining specimen, which died in 1903 and was stuffed had 6 toes on the front paws, not an unusual mutation in cats, leaving a 5-toed footprint)

(http://images.nittanyweb.com/scs/images/products/15/large/penn_state_paw_decal_3_5_inch_nittany_lions_psu_p4599.jpg)

Imagine if you will, back in the late 90's, when the admissions department put admissions info (a video tour, application forms, etc) on CD-ROMs and had them shaped like the lion's paw.  It was a good bit rounder than the above image, but the small notches cut out between the toes left it a bit asymmetric, and because they were small, the eddy currents cause it to howl like a siren when the disc spun up...

Our branch campus alone got 3000 of the discs.  System wide?  Probably 100,000 or more.  Every one of them completely useless, unless the users and their neighbors were all stone deaf. 

Learning had occurred! 

Of course, they could have just asked someone...

 Wendeday - Wodinsdagr - Odin All Father

If the district waits until the weather is really bad, people will already have set out and will be in danger trying to get home again.

I don't know what the weather is like in Virginia but it's not wussy to decide not to force people to go out in life-threatening weather. Teachers often commute for an hour or more; in bad weather they have to set off even earlier. If the district waits until the weather is really bad, people will already have set out and will be in danger trying to get home again.

Is it only the low temperatures or did the NoVa area get hit with rain or snow or icy conditions? Lowe temperatures alone shouldn't cancel school unless it's deadly lows like in the plains states...

There were some deadly wind chills, not to mention school buses aren't exactly well-heated most of the time.

I don't know about NoVa, but the mountains of Virginia got slammed with snow as well.

Not storage based on the genome, but storage of the genomes.

We are working on the effects of drugs in the human body (cancer treatment, mainly, in my department).  When comparing the effects in different people, a comparison of their genomes may be one thing that leads to a better understanding of the mechanisms that the drug invokes.  Or maybe a feature of the genome can be identified that would enable prediction of the effectiveness of the drug in certain individuals (or even of their susceptibility to specific cancers).  I can't go much further, not actually being a bioscientist myself!

I assume you're not writing the genetic code as a string of 1s and 0s directly onto a storage device, which is what the article is describing. Presumably that would require much less bits than storing it as an actual file that programs can read and write to. Even writing the genetic code as a string of ATCGs in a text document would require much more than 750MB.

Paul, that does make more sense, but now I realise that I don't really understand what a genome is and how you can store one. Are you storing descriptions of them, as data on a computer? Presumably you're not somehow stuffing little tubs of DNA samples into a computer shell.

@LTK:
Much computer storage is in binary, though, especially with huge datasets; if the code were stored in ASCII, then it would compress dramatically using common algorithms, but I know from an article on the subject I've just read that gzip compresses a conventionally stored genome by only about 35%.

@May:
The genome is the actual sequence of bases (A, T, C, G) in all the DNA of the individual; i.e. the definition of all the genes on all the chromosomes (I don't know if mitochondrial DNA is included).  Essentially it is the complete chemical formula of the whole lot.  The term "sequencing" DNA is used, because the process is determining that sequence.

While the size of the average human genome may indeed in some way somewhere sometimes be ca. 750MB, the hardware will be used to handle extremely large datasets required for sequencing, analysing, aligning and backing up millions of overlapping snippets of DNA that, taken as a whole, account for many copies of several (in the case of pharmaceutival research, perhaps hundreds?) variants (rather than single straightforward genomes).

To sate my own curiosity, I've discovered that an original Windows XP disk contains considerably less than 750MB; no more than 600, in fact. The comparison will fall down anyway, because if you follow that analogy then inserting the installation disk in the drive would prompt it to start replicating the entire system, disk included, and it would install a different set of programs on each individual system and network the whole bunch into a massive machine whose primary function is to produce half of an installation disk that is then combined with another half a disk of another network of systems.

If Windows XP did that, tech support would be a nightmare.

There has actually been a Supreme Court case where the decision was based on the Third Amendment, although it didn't have anything to do with quartering soldiers. In Youngstown Sheet & Tube Co. v. Sawyer, the court ruled that the Third Amendment shows that it was the Framer's Intent for executive powers to be limited even during wartime. The Federal Government had seized steel plants to assist in the Korean War.

Engblom v. Carey, which was decided by the Second Circuit Court of Appeals, is the biggest case that directly involve the Third Amendment. In that case, New York state prison guards went on strike and were evicted from their on-site housing. National Guardsmen were brought in to guard the prisons and lived in those homes.

The wording of that ruling is more telling: not without congressional approval. It could be done, but requires help from Congress.

Babylonian medical texts are really cool. Today, while discussing epilepsy and its association with psychosis, we were reminded of this.

http://www.ncbi.nlm.nih.gov/pubmed/18479392

Quote
The lines read in transcription:

ˇsumma amelu antaˇsubbub el uri...qat etimmi qat mamıti... eli-ˇsu ibaˇ sˇsi alu lemnu ireddi-ˇ s u...

and may be literally translated:

If a man has been suffering from antaˇsubbu, b el uri, qat etimmi or qat mamıti, and an al u lemnu then begins to in- flict him with ideas of persecution...

Of the terms mentioned, the first antaˇsubb u, is a Sume- rian loanword and has long been understood to mean the falling disease, that is, epilepsy characterized by major seizures. The term b el uri which follows means literally the lord of the roof, and was evidently the ancient term for an absence attack, the common rolling up of the eyes being caused, supposedly, by a demon lurking in such a position as the roof of a house. qat etimmi means the hand (power or influence) of a ghost, and although it may have had a wider significance, we have suggested (Kinnier Wilson & Reynolds, 1990) that it refers to nocturnal epilepsy. The word mamıti in qat mamıti literally means oath, but was used medically to denote conditions in- volving obsession or repeated action, as if the patient had sworn an oath to perform a certain action and could not be dissuaded from doing it. In the context of epilepsy, the term may readily be understood as referring to the au- tomatisms of epilepsy or postictal confusion. The words alu lemnu translate, nonspecifically, to evil demon.

There's a reason...

The Cohans (George, his parents and his sister) were residents of my great-grandmother's boarding house when they were performing in New York.  George got along famously with my grandmother, though she was about a decade younger.  Nevertheless, jokes were made of a "betrothal" (often in exchange for room and board when things were thin for the Cohans). 

George met Mary, so he never wrote a song called "Martha" (My grandmother's name), and my Gramma married a nice first generation German Engineer instead.  But had it gone a little differently...

Well, my last name would be Cohan.  Of course, it wouldn't be me, but... you get the idea.

Everything is in great shape and so ridiculously sturdy, with all cabinets fitted perfectly... and stuck fast to one another so tight it's like the entire kitchen is just one single many-doored multidimensional indestructible cabinet.

In taking it apart (aka wrecking it) I've learned a little about cabinet-making, but, more importantly, I've come to the realisation that the crowbar is one of my favourite tools. So simple and elegant, yet so versatile. Two lever classes, a makeshift chisel, a hammer, a nail-puller... it's just beautiful. I have also learned that they used to be called "iron crows".

A couple of times I have come across brief, unexplained references to hot and cold theory in relation to Chinese culture. I also came across the concept as a more wildly-held set of beliefs in other countries in the ?17th century. I've started looking into it a bit, but can anyone, such as Akima, expand on the concept? I'm reading this article (http://www.pacificcollege.edu/acupuncture-massage-news/articles/471-theory-and-practice-for-traditional-chinese-medicine.html) as a basic overview but wondered if there were regional variations and how much it's still believed or practised.
Title: Re: Learning has occurred
Post by: Akima on 08 Apr 2014, 20:07
I am not trained in Traditional Chinese Medicine (TCM) (http://en.wikipedia.org/wiki/Traditional_Chinese_medicine), and having received a modern scientific education, I am skeptical about many aspects. However TCM is very widely accepted in China, throughout China's zone of cultural influence in East/South East Asia, and wherever there is any significant population of Chinese people. In Australia, practitioners must be registered under the national registration and accreditation scheme with the Chinese Medicine Board of Australia, and meet the Board's Registration Standards, in order to practise legally. Regardless of the actual efficacy of TCM, its cultural influence is immense. There is a widespread idea, for example, that drinking cold water is damaging to the stomach, which is tied to TCM ideas about heat and cold, though it might well have had a purely pragmatic basis when unboiled water was not safe to drink.

TCM is very old, long predating any scientific understanding of disease, and has many similarities with the ideas of the Ancient Greeks (which persisted in Europe until at least the 17th century), particularly the idea of bodily and emotional health being based on the "humours (http://en.wikipedia.org/wiki/Humorism)". TCM also is heavily influenced by Taoist ideas of balance between opposing forces (http://en.wikipedia.org/wiki/Traditional_Chinese_medicine#Philosophical_background), among which are included heat and cold, two of the "Six Pernicious Influences." The basic idea is that certain foods, medicines, and activities promote heat or cold, and that if a patient's symptoms suggest that they are suffering from an excess of either, diet or herbs will be suggested to exert a countervailing influence.

Post by: Barmymoo on 09 Apr 2014, 01:51
Yes, it was the humours I was thinking of but couldn't remember the name of. Thank you, that's helpful. Like any other cultural practice I won't assume it applies to all Chinese families I meet, but it's definitely helpful to be aware of the possibility that a Chinese woman might prefer not to have ice in her water jug, for instance (fetching jugs of water is a good first year student task!).

At the age of 13 I stayed in the South of France for a couple of months, in high summer.  After a while I came up in hives, to the extent that my hosts took me to their doctor.  He told me that the iced water I was drinking because of the heat was upsetting my liver; so I stopped, and the hives went.

This is definitely something I've read about elsewhere - an article about cultural awareness vs stereotypes, I think. A study found that Chinese and South Asian women had higher rates of dehydration following delivery, and they eventually discovered that it was because the women were refusing the ice chips that the hospitals usually provided.

Title: Re: Learning has occurred
Post by: GarandMarine on 09 Apr 2014, 23:47
That's kinda like the modern Marine Corps usage, where it's used to describe an enthusiastic or motivated individual or unit in addition to it's traditional place in Marine Corps terminology as a battle or rallying cry. It can also be used with a slightly sarcastic bent to imply one is TOO motivated/enthusiastic.

As Akima said else where the translation works out, but is still probably terrible Chinese. From what I understand "Gōng h" is a shortened version and slogan of the "gōngy hzush" (工業合作社) or Chinese Industrial Cooperatives, which was abbreviated as INDUSCO in English. It entered usage with the Marine Corps courtesy of Major Evans Carlson, famously of the 2nd Marine Raider battalion in WW2, sayeth the Major: "I was trying to build up the same sort of working spirit I had seen in China where all the soldiers dedicated themselves to one idea and worked together to put that idea over. I told the boys about it again and again. I told them of the motto of the Chinese Cooperatives, Gung Ho. It means Work Together-Work in Harmony...." from the 2nd Marine Raiders the term spread through Marine Corps culture and language, with the help of touchstone pieces like the movie "Gung Ho" about the 2nd Marine Raiders, and it's now a firmly entrenched part of Marine culture and vocabulary.

http://www.angelfire.com/ca/dickg/gungho.html

This short paper however suggests that even what I learned is off, and that the Major was primarily inspired by the Chinese 8th Route Army, who themselves used to the term. *shrug* we were taught the above about Gung Ho in boot camp, even as we learned what it meant, I've never heard the bit about Carlson's time with the 8th Route Army before.

Yes, it is. "Work together" is just the meaning of the individual characters, it's not really proper Chinese at all. A more correct way to say "Let's work together!" would be 共同努力吧 (gngtngnǔlba).

Quote
A couple UK scientists, wondering how Bactrian camels in the Gobi desert were supposedly able to sniff out water from 50 miles away, proposed that the animals were actually smelling geosmin carried by the wind from oases.

A survival trait so obviously useful to camels would likewise be advantageous to us. Long ago we were mainly nomads wandering in arid regions. Its easy to imagine a parched band trudging mapless in the desert looking for the next watering hole. Then the breeze picks up, and what do they detect? Had they lacked the appropriate olfactory adaptation, nothing, with possibly disastrous consequences. As it was, if they were fortunate, they might smell the faint odor of moist earth, and with it the promise that they'd live another day.

Some time ago I was wondering how desert animals are able to do that when there are no olfactory receptors for water. So learning has occurred once more!

Lumber mills historically burned such things as waste materials, and the furnaces were called "hogs", perhaps because of their appetite. Thus the scraps became "hog fuel".

I learned that the Russian monarchy stopped calling themselves Tsar during the reign of Peter I and was changed to Emperor.  So any "Tsar" after his reign was actually not a Tsar but Emperor. Many Western European monarchs declined to recognize the switch in title. To them the word emperor connoted superiority over kings. Several rulers feared that Peter would claim authority over them, just as the Holy Roman Emperor had in the past.  This cultural biased may explain why many documentaries in English refer to the emperors after Peter I as Tsar.  Or lack of caring about the subject's own cultural perception.

So the last Russian Romanov monarch wasn't Tsar Nicholas II but Emperor Nicholas II.

4. Firing pin move rearward
5. Cocking piece stops on safety switch
6. Firing pin spring stops on cocking piece
7. Firing pin stops on cocking piece

Probably something along the lines of (assuming the individual was firing)
Trigger rotates CCW
Sear Rotates CCW
Sear spring decompresses
Bolt Carrier Assembly moves forward
Bolt Carrier Assembly stops on sear
Sear stops on receiver tube
Sear spring stops on sear
Trigger stops on sear

Then of course the mechanical actions in the human hand for the act of moving your finger...

Have you ever wondered how computers truly handle decimals? If you have, you probably stumbled upon some info on floating point decimals and IEEE754, but I had to wrangle with it for some guys I TA. Turns out that floating point sum is a really slow and painful process, that can take up a massive amount of software cycles. That little task is something that makes me respect hardware engineers even more.

(click to show/hide)

On the actual process of the sum, there are 4 main steps:

Step 1: Equalizing orders of magnitude. The Float single precision format represents a number that's like (1.)<23 bit binary> * 2^<8 bit binary>-127. So the sum will always have the exponent part of the greater number. The fraction of the smaller number is then moved right n bits, where n is the difference between the greater and lesser exponents.
Note that if the difference between exponents is greater or equal to 24, then the value of the sum is defaulted to max(a, b).

Step 2: Sum the fractions. Keep in mind that if one of the values is negative, you need to sum the 2's complement of that fraction with the other one.

Step 3: Normalize the fraction. To do this, you sequentially move the fraction left or right until the 24th bit (or position 23) is the first 1 in the fraction, and for each bit moved right you add 1 to the exponent, and for each bit moved left you substract 1 from the exponent.

(click to show/hide)

Step 4: Put everything back together and check for inconsistencies. Keep in mind that, even if it hasn't been specified explicitly here, you should handled un-biased exponents. Exponent bias is inserted to keep exponents as positive and consistently increasing, so the exponent should be considered an unsigned byte and its real value is the one in the unsigned byte minus 127 (in the case of single precision)
Title: Re: Learning has occurred
Post by: Masterpiece on 12 Nov 2014, 13:56
The reason numbers are represented in this form is because statistically, the most common operation performed on a number is a comparison with another.

So in a best case scenario one of the two numbers compared is negative, so the machine only has to check the first bit of the number. Next up are the exponents - if the bits do not match up, you know as soon as you hit the bit that is not equal to the bit on the other number. Best case scenario? You just had to check two more bits in both numbers. All without having to rearrange the floating point decimal to a real number.

I think floating point decimals are amazing.
Title: Re: Learning has occurred
Post by: osaka on 12 Nov 2014, 14:00
Indeed. And it's also great for RadixSort, specially if you use the "Most Significant Bit" variation of it - with the exponent at the beginning, most of the time you'll have almost all numbers sorted in no time.

Aye, I'm generally decent about it, myself.  My homing instinct tends to kick-in when I've had too many, and I've never had a hangover that couldn't be cured by greasy food || Clonazepam || more booze and a lot of water.  Then again, I also understand why some belief systems are against drinking, or at least, getting drunk.  I've had to pick up people from the floor of the women's toilets to get them into a taxi back to their home (I feel sorry for the boyfriends and flatmates who had to deal with any aftermath), and seen people make really questionable decisions. 

Made a few of my own, that helped fuel regret, and re-igniting a doomed relationship.  Lowered inhibitions may make a good social lubricant for the shy, but there are certainly times in life where they do not help.

Well, it's partially genetic, and I always match each drink with a glass of water to avoid them in the first place.  When that fails, I go for either a proper English or Irish breakfast, sedatives, or a hair of the dog that bit me.  It also helps the next day to force down a banana, and drink water with a little bit of salt to restore the electrolytes.  And that's irrespective of whether or not I've done any of the previous things.

well, it has been noted that even the smell of coffee can produce a heightened alertness & wakefulness in habitual coffee drinkers. that is to say, that with a strong enough conditioned-response, the body can mimic the caffeine-high before caffeine has even entered the system.

it would be interesting to do a double-blind study on heavy coffee-drinkers as to whether they can distinguish the difference between decaff and regular coffee when not informed, or misinformed.

a similar study on wine aficionados has shown that cheap wine served from an expensive bottle will be perceived as being much higher quality than when it is from it's own bottle. said aficionados report enjoying said wine much more, and being unable to distinguish the incongruity when presented with a misleading label.

No, you aren't.  But I've worked in enough coffee places to the point where I can taste the difference, as well, as the one between different roasts, and to some extent, origins.  It's a lot like tasting whisky, there are different types, places of origin, single-malt versus blended, and totally different tasting notes.  My biggest problem with decaf is that it's almost *always* over-done, in terms of roasting.  I'm not a big fan of dark roasts to begin with, I tend to prefer the light roasts or blended ones, but every decaf I've ever had, it was basically burnt.  I don't know whether or not it's *needed* to always roast decaf as dark, but it's *not* the same, even compared to other dark roasts.

Depends on your risk level. Although a communicable disease, it's transmission is limited. As a monogamous person in a long-term relationship with no likelihood of exposure then there's no real value in getting a vaccination. However, if the relationship were to break down or we were to start engaging in riskier sexual behaviour then it might become worth it. Casual herd immunity isn't a factor here. The trick really is to be frank and honest about your current or imminent risk level. It's something the humans are typically quite poor at.

You don't need to do the experiment, it's already been done.

Studies were carried out into the amount of pollution ingested by cyclists and pedestrians in comparison to drivers. The study had initially expected to show that pedestrians and cyclists were being unduly affected by air pollution caused by road traffic. What the studies did show that pedestrians and cyclists did ingest more large particulate pollution, occupants of motor vehicles were shown to ingest larger volumes of the small particulate pollution. The smaller particulate pollution is the more harmful and more likely to cause cardiac and respiratory disorders. Tests were conducted on modern vehicles with closed windows so the majority of the pollution was coming through the air filter.

If enough of the particulate matter in pepper spray is small enough, it's going to pass through an air filter. Same as when you can tell someone has run over a skunk from several miles downwind while driving along a highway.

Do you know what was the year, make, and model of the following car? (So I can get the right type of filter from work)

Also, what kind of pepper spray did the instructor use?

I don't know, but what he teaches is to select OC unblended with CN or CS, in an alcohol carrier. No idea whatever about the car. Uhh, how could you do that experiment safely? Closed course? Driver in PPE and passenger serving as canary while operating a driving simulator?

You say that as if they could not do both at the same time. The narrative with which the page you linked is running seems to be that as long as you warn people ahead of time that you are going to employ violence against them, or spray them with a not-intentionally-lethal (http://articles.latimes.com/1995-06-18/news/mn-14572_1_pepper-spray-manufacturer) chemical weapon, that makes it OK.

As for the "the protesters were told they were breaking the law" line, I'd have to say "Duh! Of course they were; isn't that the whole point?!" The laws were made and enforced by the power-structures against which the protesters were protesting! From at least the days of the Riot Act of 1714 it has been routine to criminalise protest, so drawing attention to the illegality of the UC Davis protest is rather like saying that the sea is wet and salty.

The barrel boss in level 3 of Carnival Zone in Sonic 3 was worse, because you pretty much had to find a guide to figure out how to get past it (time pressing up and down as it moved up and down).

That whole level was a charliefoxtrot, honestly.  Massive for one, the aforementioned barrel boss, and a zone boss that required certain items to appear before you could hit him, meaning that there was practically no time to go exploring or get lost.  I almost never reached the boss with over a minute remaining, and never managed a no-deaths clear.

Turns out that in strict usage any abbreviation for which you spell out the individual letters, for example IBM, is properly called an "initialism" with the word "acronym" reserved for things that are pronounced as a word, e.g. NATO.

SAP, then, is an initialism when used by people who work there and an acronym among their customers.

Spain has been a republic twice for a combined 6 years but it never went what you'd say "well". The first republic had a new head of state every two weeks for several reasons (assassination, resignation, putting a scapegoat...) which eventually made the citizens decide that constitutional monarchy would've been a better idea and the second one devolved into a civil war and dictatorship after 5 years because that Franco dude staged a coup and shit.

I use the upper left notation for long division (omitting the "-" though, like 42:3=14) - i.e. never - and the bottom right one as default. Mostly because it's easy to visualize manipulating fractions, like:

a/b = c/d => a/c/d = b => a*d/c =b

where I'd imagine the c/d "flipping over" in the last step.

Aaaaaaand I just learned that one actually has a name, and it's called "cross-multiplication" (https://en.wikipedia.org/wiki/Cross-multiplication). Huh ...

When I divide I tend to use the bottom left format so I don't even see the other ways too often.

Huh - didn't even know that one existed ... looks a bit like 3*Sqrt[42] ...

I know for the most part that's the method they use to teach long division in Primary School here.

That's weird - I mean, the graphic format is similar to the conventional notation for long division, but the notation goes against the common reading direction, and it doesn't conform to the equation format  :? Feels wrong somehow.

Do kids learn better that way?

(And I never understood the need for mnemonics - it's just math, it is its own language, much like music. Why mix it with weird mnemonics about smelly dead animals? Gives all kinds of distracting associations)

The graphic is not displaying equivalent notations; there is a clear difference between writing a division relationship in text or a formula (which may be one or two dimensional), and a layout convention for conveniently performing a tedious calculation.  Bottom left is the second of those, and the others are the first.  I can't imagine that anyone has ever suggested bottom left to be used like the others.

Today I learned that "Cathar" and "cathartic" have the same Greek root.

Today (wee hours of the morning) I  learned to not waste time and effort to get equipment to pass when your standard is effed up and off by your acceptance limits.

Don't trust and always verify.

I was just wondering how pineapples reproduce, because they don't have seeds, and I'm pretty sure they haven't been cultivated to grow a seedless variety like bananas and grapes. Apparently, unpollinated pineapple plants still grow fruits, and the pineapples we eat are all unpollinated. Pollinated plants will grow seedy pineapples (https://qph.ec.quoracdn.net/main-qimg-23c9ed60a87b9083cfc273a7579d10a6-c?convert_to_webp=true), which are less desirable for obvious reasons. Hummingbirds are prohibited in Hawaii as they would ruin the pineapple harvest by pollinating all the plants.

I'm not sure why a pineapple plant would spend all that energy on producing a fruit that has no seeds and cannot reproduce. Or can it...? The other thing I learned is that pineapple plants are really easy to grow yourself (http://www.tropicalpermaculture.com/growing-pineapples.html)! All you need to do is cut off the crown and stick it in a pot. Needs very little water and a little plant food. It'll grow easily, even in non-tropical climates, and then you can look forward to harvesting your very own pineapple... in about two years. Okay, it's not quick, but it seems like a fun thing to try out. It can hardly be more disappointing than the time I grew an avocado plant...

I just learned that the movie Final Destination is based off a scraped X-Files episode. It kind of has the same vibe looking back on it. Would have loved to see Scully and Mulder do an investigation.

If you ask google how to cook bacon in the oven, you will find a plethora of articles advising you to set your oven to 400F (200C). One even talks lovingly about the benefits of cooking bacon slowly ("Starting with a cold oven ensures that the bacon will cook slowly like it needs to.") But it still suggests setting the temperature to 400F.

Even starting from a cold oven, you will probably end up with a smoke-filled kitchen.

We've got a copy of the excellent book "Salt, Fat, Acid, Heat." The author points out that animal fats begin to burn at 176C (about 350F). Just below that, fat will render and the bacon will brown as this happens.

If you've never done this, I can highly recommend it. Lay your bacon in a single layer on a lined tray (I put one layer of alfoil and top that with baking paper). Put in cold oven. Set oven to 175C (adjust for your oven). Give it a turn after 10 minutes or so. Pull it out when it's done to your liking.

No smoke. Crispy bacon. And a lot of fat is rendered off (which you should, of course, keep for some other happy purpose).

wow, I finally understand the song "we didnt start the fire" by Billy Joel. I always thought it was about some deep meaning commentary on the human experience. Turns out its just a list of events from 1949 - 1964.
 :venonat:

To be fair to my younger self some of the lyrics are movies or songs released in those years that reference history before the era.

People and events... but it goes WAY past 1964...
Punk Rock is mentioned (late 70s) and the 'cola wars' (mid 80s).

The other day I learned there's something called "Luftverbrauchssteuer", literally "air use tax".
If you add something to a building exceeding a certain height beyond your roof, you have to pay a tax, as you occupy a certain amount of air. And there's a tax on that.
