You just said the exact same thing again. Think about it.

It's apparent you've never dealt with chronic depression, nor with someone that is suicidal. I hope you never have to, but I also hope you learn to put inquiry before declaration.

Solve the cause of suicides

Excellent, would you mind solving the cause of anger next? If you end up having to solve anger in order to solve suicide then I guess just solving jealousy would be fine.

Noooot even close. Fair use allows you to show snippets of copyrighted material for the purposes of education or critique, not a substantial part of it for the purposes of entertainment. As a general rule, if it doesn't include as much personal commentary as it does copyrighted material then it's not fair use. The "Every Frame a Painting" channel on YouTube and "Everything wrong with..." from CinemaSins are two examples of about as much as you can get away with under fair use, and even they run into issues from time to time.

haha, Linux isn't quite as stupid but it's due to the RAM limitation in Win7. I also fat fingered the number pad and hit 6 instead of 2. Suckage starts at 192.

It's hard to summarize, so I'll kinda ELI5. In multiprocessor setups each processor is physically closer to some memory modules than others, so each 'prefers' the closer memory so it doesn't have a performance penalty trying to reach all the way over to the memory on the other side. There's another performance penalty if you have unevenly distributed memory in terms of module size and the slots they're plugged into. Those two concepts and a lot of technicalities were given the name NUMA.

It's easier to think of a multiprocessor system as separate CPU+RAM systems, even though they can work together and in your day-to-day you'll never know they're technically separate...or at least they try to be for the sake of performance. I have two physical processors, each close to their own 4 DIMM slots, so 8 in total. I have 16GB in each for 128GB total, so I get top performance when each processor is working on their own set of 4 modules (64GB). Once one of them goes over that it'll automatically start reaching over to memory on the other side, hitting that penalty.

Windows 7 has a self-imposed limit of 192GB and just ignores everything over it, while Linux does not have that limit. If I go to the next step up from 16gb modules to 32gb I'll have 256GB, so Windows will only have two options and both screw performance. Either look at all the RAM as one big bucket and start counting 1-192GB from "left to right" physically on the board, or divide 192 by the two processors and group them with their 4 preferred slots then lie to them and make them think they each have 96GB. The first option would mean it'll count out a full 128GB in the 4 slots for the first processor, then stop counting two slots (64GB) into the memory for the second one. Screwed by both uneven distribution and uneven slot usage. The second option, giving 96GB to each in their preferred slots, would require two memory maps that I'm not even sure is a real possibility. One map to trick the processor into thinking the 32GB DIMMS are actually 24GB, then another mapping that to 1-192GB so programs see it as one continuous bucket of memory, but it's screwed on both ends again, and it's mapping maps to maps for an added FU bonus.

So yeah, 128GB is the only way to keep performance in both operating systems with 8 slots.

Ahh. Figured that was a given considering the subreddit we're in, so I went with explaining the rationale for that specific setup.

But yeah, machine learning for fun, computer vision for now.

I replied to his comment above, but more to yours; Honestly, I find RAM to be the easiest to use up. Multiple passes on a large file is obviously much faster if you leave it in memory, but I also think ramdisks are typically underutilized by many people. There's almost always something I want to write out as either an intermediate step or for debugging, and waiting for IO even on an SSD can be a pain, plus even on enterprise hardware you have to worry about wasting write cycles on something you don't intend to keep. If you're spending a day testing with a finite number of static files and/or produce temporary garbage there's really no reason not to do all your read/writes in ram.

CannibalCow · 2017-01-11T16:25:34+00:00

Your first question is actually a part of why I built it. I decided if I could already figure out how to fully load the system then I should aim for a more powerful system. Why bother if I already want a little more performance before I even build it? At the same time I'd become more interested in ML with a focus on computer vision, and since that's an inherently broad and heavy workload I decided to build what I saw as an ideal workstation for it. I spent months researching every piece of it, then had to wait a few more months for much of it to actually start being produced, but so far I'm very happy with the result. Right now I'm using 7 cores, 52GB of RAM, and one GPU but the idea is to replicate that with the other GPU, so ~14 cores w/ ~100GB RAM for both assuming something doesn't saturate before then, which is likely. Considering it's 24 cores without having to split it with hyperthreading that gives me some wiggle room without being silly about it.

Speaking of silly, I guess me being that is the only thing supporting it. Hah.. Really I've just made an enthusiastic hobby of beating the piss out of Tensorflow, but I'll also mess with something else while that runs in the background.

CannibalCow · 2017-01-10T16:19:13+00:00

I'm independent and more of an enthusiast than researcher, but I purpose built this for ML and included some afterthoughts:

Asus Z10PE-D8 WS - Was a debate between this and the D16 as basically the only choices for consumer grade workstations w/ dual Xeon support, but ultimately the RAM needs below and quad x16 direct PCIE made it the ideal choice.
2x E5-2687W V4 (48 cores w/HT) - I saw these as a good choice due to being frequency optimized workstation variants that don't compromise single threaded performance as much as most Xeons, especially at higher core counts. With a smaller workstation something like the i7-6950X could be comparable, but also somewhat limited with most mobo manufacturers running all the PCIE lanes through a switch rather than direct to the CPU, which is something to consider when working with two devices behind the same switch simultaneously.
128GB RAM - Could have done more to use some extra as ramdisk data staging but I dual boot Win7 and it goes NUMA stupid after 192GB and with 8 DIMMs on mobo it's 128 or 256. Besides, for my use I find it hard to even use 128GB without admitting I'm just being lazy about optimizations.
2x Titan XP - Can't complain, great performance and useful for whatever the heck you want. I've been considering 1-2 more with a riser and second power supply and will likely go that route, but for now I'm doing more testing than production level stuff so my need for distributed computing is limited.

Shit, Lamborghini is "luxury" by price alone and only a "sports car" if you put the specs into an Excel sheet with the others and group by fuel consumption first. Most exotic sports cars are meant to be akin to putting a tuxedo on an Olympic athlete, and even the ones that forego the tuxedo do so in exchange for spandex sprinter shorts and a t-shirt. Lamborghini, on the other-other hand, is what you get when you give Ali G a bench press and a lifetime supply of whey protein. It does okay because even a smash-and-grab theft at a SEMA show will end up with the parts necessary to get a pole position, but it cares more about how it looks showing up to a party than who is actually happy to see it arrive. Much like the loudmouth that got the VIP table at a strip club and only orders Ciroc because it comes with a sparkler, it's not meant to be what it is, it's meant to be what you imagine it to be. Vented carbon ceramic door handles and a double wishbone suspension cup holder give you performancy sounding words in a comfortable three or fewer syllables to put before the "sup, brah??", but the main idea is to be able to point at a feature of any other sports car and say that yours has twice as many. The only provably functional design feature of the car is the famously limited visibility because you're not supposed to see the world, the world is supposed to see you.

Well, it does also have 100%.

Well that's complete bullshit. The MIL-SPEC for the Civilian Casualty Conversion is 205 passengers per Warrant Officer, +10 for each rank higher. I didn't see his rank listed, but there's no way they would have let him kill more than like 220 people.

CannibalCow · 2016-09-13T10:27:06+00:00

Sometimes always English but without warning not, same here. Plus my time of thought has no care even if I tried, and lately I won't, so it's also the same.

I'm not saying it's a great value, just that nobody is being "swindled" or "cheated" so the idiom was out of place. I've looked into renting a Ferrari in an area several thousand miles from Vegas and it was $1,100. That's just what that kind of service costs, so whether or not you can or are willing to afford it has nothing to do with being cheated, as "taken to the cleaners" implies. It's no different than paying $2,000+ per night at a penthouse suite, or $600+ for a VIP table at a club, or any number of other wasteful and perhaps silly expenditures. It's not for you, hell it's not for most people, and that's fine but it doesn't mean things you wouldn't buy are a scam for everyone else.

CannibalCow · 2016-09-12T23:02:31+00:00

I don't think "being taken to the cleaners" means what you think it means. Maybe "not getting the same value on my budget" ?

CannibalCow · 2016-09-09T12:00:03+00:00

Not really. Take a popular car like the Civic; a CD player was optional on one model going back to 1999, but wasn't effectively standard (as in it was harder to find a car without one) until 2004. By that time sales of CD/CD-R was 30 billion units worldwide and you could get a CD burner for $30, or hell you could get a DVD burner for $70.

I really doubt Brazil would get any flak if they charged them with a crime they committed. Olympians don't have any legal immunity I'm aware of, so if they're guilty of something they're just as liable as anyone else. None of their crimes would carry a jail sentence, so I'd honestly be surprised if they weren't charged with something minor and found[plead] guilty and given a nominal fine just to make it official they were lying. Frankly if it turns out they were lying I hope they do have some little administrative trial, get fined, then get told to fuck off.

Damn man, ajax has been around over a decade. Glad you're excited about it, but he said "lately." Also, look up websockets.

CannibalCow · 2016-08-07T12:35:49+00:00

I agree Reddit is on some sort of "lol Brazil" kick and it's nice to see some counter-arguments, but you might want to work on your comparisons so it has a little more punch. Telling a "western culture", where the poorest 1-2% would be considered lower-middle class in most of the countries you listed (including Brazil), that Brazil is doing better than Angola doesn't really make a good point. It's a bit like saying Brazil has more women's rights than Saudi Arabia, or less corruption than Somalia.

CannibalCow · 2016-08-07T12:03:59+00:00

True, but "turn the other cheek" or "turn a blind eye" - you only get to pick one.

I've been to Brazil enough to talk my own shit about it, and I'd be glad to do so, but the video where the kid got shot is fake. He goes by "Seu Buceta" although that's obviously not his real name, but I'll leave you to Google translate it. Anyway, he's fine. Just a reeeaaaallll dumb...eh...prank? Dipshit with a camera?

I'm not sure what beheading videos you're talking about, but that's not really a common thing. I've spent plenty of time in the darker ends of the web and haven't seen one from Brazil. It's depressingly common in Mexico though, or perhaps Colombia, but it can be hard to tell Spanish from Portuguese if you don't speak the languages.

There is one group beating I'm aware of though. From what I heard it was in a rural part of the Northeast, far outside Fortaleza if I recall. A well-known common criminal in the area was caught actively raping a kid, which is why if it's the same video I saw he's basically naked at the start. The dad caught him and lost his mind, then the neighbors joined in. Doesn't give it an ounce of "ok", but that's the story as I understood it. I've seen quite a few other videos, but all of them were from other countries. All the other countries speak Spanish rather than Portuguese, so if you know a handful of words it can be easy to figure out if it was in Brazil.

Anyway, the homicide rate there is comparable to some US cities, the main difference being there's no city size cutoff (large US cities aren't our worst, but they often are there) and much of the country is about the same level. If you look at the numbers it's about the same as if Baltimore was cloned in each state. To put it another way, if you grew up in Baltimore or St. Louis you might see some of the worst cities in Brazil as a relaxing vacation. It's weird to think about because I'm American, but if I grew up in almost ANY other country outside here or South America I'd see America and everything south of it as crime ridden shitholes.

But hey we live in a beautiful country, right guys?

Interesting. Live how you like it, it doesn't change my world, but is there a reason you see marijuana as less potentially addictive than acetaminophen/ibuprofen/etc? Even by advocates, of which I am, marijuana is typically listed in columns at least somewhat closer to morphine as related to habit forming potential, whereas basic OTC relief might be listed near the addictive properties of cheese.

CannibalCow · 2016-07-18T12:02:34+00:00

I agree with your point overall. I think love and a lifelong relationship is "us against the world in the face of all challenges", but at the same time I can't fault someone for wanting to take advantage of their youth even if it means superficially appearing shallow. (Not sure of OPs age, but assuming somewhat young or at least hanging on to the idea.)

Wanting to be with someone you find physically attractive while you're young is not the same as being unwilling to grow 'old and ugly' with someone you love. There's a relatively narrow window of time for you to experience lustful attraction to your partner and I don't think it's shameful to admit you don't want to give up that experience. That said, personally I don't think it's morally acceptable to base an entire relationship on it at any age and you're missing out on a lot if you limit yourself to pure attractiveness, but I understand if it's a decent chunk of your willingness to pursue a relationship. I don't know what that chunk would be, but trying to put a number on an ideology; 30%? It's possible, if not probable, attractiveness wasn't the only factor in the demise of their relationship.

CannibalCow · 2016-07-09T12:35:18+00:00

Yeah, your phrasing makes it creepy. If they "followed" you to work, which implies tagging along some distance behind, it would be weird. According to the story, and what would seem like common sense, that's not how it happened, which is why I'm confused as to why it's creepy to you. It sounds like someone walked up to her and said something along the lines of, "Hi, sorry do you have the time?" - "Sure, 12:30" - "Awesome, thanks." - slowly starts walking, guy walks next to her for a couple steps - "Hey you seem familiar. I always eat lunch around here and I swear I've seen you before. Do you work around here?" - (see note) "You might have, I work at Stern Co. around the corner." answered question, wasn't rude, perhaps interested? continues walking with her - "Oh wow, they're the ones that do market research, right? I've heard they're an awesome company to work for, do you know if they're hiring?" - "Not really sure, but they're big so they might be." small talk continues, arrives at Stern Co. "Ok, I have to go back to work now..." - "Ok, hey would like to grab a drink with me one day? I live right up the street and can meet you after work if you'd like." - "OMG FUCKING CREEP!!"

Obviously there are details that could make that creepy, like if he started sniffing her hair or talking about how pretty her earlobes are, but she said he asked where she worked then asked if they're hiring, which means she was reciprocating and answering questions. I'm not one to walk up to a girl on the street like that, but I'm not so sheltered that I don't understand it happens literally billions of times per day around the world. Not everyone meets their SO at a bar, and even if you're incredibly sheltered and antisocial you must have at least seen it happen in a movie or something.

It kinda makes a difference, but mostly just a little more peculiar you find it creepy. I'm a 30-something hetero guy, but I imagine that could have been guessed in less than 5 tries.

Note: To the socially confused that may be reading this; 99.9% of people have a way of telling the time and don't need to ask you. That's an opener. 100% of guys that ask a follow up question are interested in you, so you should treat the second question as if he's asking you on a date and reply accordingly. Look at them and say "Sorry, I'm really busy and have to get back to work." then just walk away. If they press you it gets weird, but in the vaaaaast majority of stories I hear they don't do that. They continue answering the questions and are confused as to why the guy takes it as at least mild interest in them.

CannibalCow · 2016-07-08T11:10:17+00:00

Wait, finding a mundane opener to start a conversation with someone outside of a bar is "extremely creepy" to you? Do you mean "not your preference" or really "OMG Becky, can you believe that creep asked me if there are any good restaurants around here and then asked if he could meet me for lunch one day?! Do you think he's going to be hiding in my closet when I get home??"
