Guidelines:
What to Submit
On-Topic: Anything that good slackers would find interesting. That includes more than /g/ memes and slacking off. If you had to reduce it to a sentence, the answer might be: anything that gratifies one's intellectual laziness.
Off-Topic: Most stories about politics, or crime, or sports, unless they're evidence of some interesting new phenomenon. Videos of pratfalls or disasters, or cute animal pictures. If they'd cover it on TV news, it's probably lame.
Help keep this hole healthy by keeping drama and non-drama balanced. If you see too much drama, post something that isn't dramatic. If there isn't enough drama and this hole has become too boring, POST DRAMA!
In Submissions
Please do things to make titles stand out, like using uppercase or exclamation points, or saying how great an article is. It should be explicit in submitting something that you think it's important.
Please don't submit the original source. If the article is behind a paywall, just post the text. If a video is behind a paywall, post a magnet link. Fuck journos.
Please don't ruin the hole with chudposts. It isn't funny and doesn't belong here. THEY WILL BE MOVED TO /H/CHUDRAMA
If the title includes the name of the site, please leave that in, because our users are too stupid to know the difference between a url and a search query.
If you submit a video or pdf, please don't warn us by appending [video] or [pdf] to the title. That would be r-slurred. We're not using text-based browsers. We know what videos and pdfs are.
Make sure the title contains a gratuitous number or number + adjective. Good clickbait titles are like "Top 10 Ways to do X" or "Don't do these 4 things if you want X"
Otherwise editorialize. Please don't use the original title, unless it is gay or r-slurred, or you're shits all fucked up.
If you're going to post old news (at least 1 year old), please flair it so we can mock you for living under a rock, or don't and we'll mock you anyway.
Please don't post on SN to ask or tell us something. Send it to [email protected] instead.
If your post doesn't get enough traction, try to delete and repost it.
Please don't use SN primarily for promotion. It's ok to post your own stuff occasionally, but the primary use of the site should be for curiosity. If you want to astroturf or advertise, post on news.ycombinator.com instead.
Please solicit upvotes, comments, and submissions. Users are stupid and need to reminded to vote and interact. Thanks for the gold, kind stranger, upvotes to the left.
In Comments
Be snarky. Don't be kind. Have fun banter; don't be a dork. Please don't use big words like "fulminate". Please sneed at the rest of the community.
Comments should get more enlightened and centrist, not less, as a topic gets more divisive.
If disagreeing, please reply to the argument and call them names. "1 + 1 is 2, not 3" can be improved to "1 + 1 is 3, not 2, mathfaggot"
Please respond to the weakest plausible strawman of what someone says, not a stronger one that's harder to make fun of. Assume that they are bad faith actors.
Eschew jailbait. Paedophiles will be thrown in a wood chipper, as pertained by sitewide rules.
Please post shallow dismissals, especially of other people's work. All press is good press.
Please use Slacker News for political or ideological battle. It tramples weak ideologies.
Please comment on whether someone read an article. If you don't read the article, you are a cute twink.
Please pick the most provocative thing in an article or post to complain about in the thread. Don't nitpick stupid crap.
Please don't be an unfunny chud. Nobody cares about your opinion of X Unrelated Topic in Y Unrelated Thread. If you're the type of loser that belongs on /h/chudrama, we may exile you.
Sockpuppet accounts are encouraged, but please don't farm dramakarma.
Please use uppercase for emphasis.
Please post deranged conspiracy theories about astroturfing, shilling, bots, brigading, foreign agents and the like. It degrades discussion and is usually mistaken. If you're worried about abuse, email [email protected] and dang will add you to their spam list.
Please don't complain that a submission is inappropriate. If a story is spam or off-topic, report it and our moderators will probably do nothing about it. Feed egregious comments by replying instead of flagging them like a pussy. Remember: If you flag, you're a cute twink.
Please don't complain about tangential annoyances—things like article or website formats, name collisions, or back-button breakage. That's too boring, even for HN users.
Please seethe about how your posts don't get enough upvotes.
Please don't post comments saying that rdrama is turning into ruqqus. It's a nazi dogwhistle, as old as the hills.
Miscellaneous:
We reserve the right to exile you for whatever reason we want, even for no reason at all! We also reserve the right to change the guidelines at any time, so be sure to real them at least once a month. We also reserve the right to ignore enforcement of the guidelines at the discretion of the janitorial staff. Be funny, or at least compelling, and pretty much anything legal is welcome provided it's on-topic, and even then.
Do not use outdated operating systems that are unsupported to access SN. What are you, poor?

I have 256GB of ram in my desktop. This is just laptopcels posting their L's.

I load my entire 2TB drive into RAM every time my computer boots. When you're a speedy hackster like me, SSD's can't keep up. The 2 millisecond delay reading files from disk costs me the equivalent productivity of 3.2 man hours of a normal person's time. When I am waiting for vi to load from a hard disk, I can physically feel my hair growing longer

I can see it is very hard for people to imagine that applications exist beyond basic word processing and bideo games. The spectrum of users here seem to range from neets all the way up to admin assistants. It is much easier and much faster to do any kind of data analytics if can fit the data in memory. In the last couple of years, polars and duckdb have made this a lot better, but its stll way better to be in memory. With pandas or R, its especially important.

When you grow up and get tired of playing with pythons and pandas, you can join the adults by investing in a real analysis machine. In my world, we inspect packets at the individual electron level to get the jump on low-tech chumps like you.

I dont trade for myself and returns are only part of the story. Let me just give everyone a pro tip: if you read something in the press about trading and it talks only takes about returns but not risk, correlation to othet assets or drawdown profile, you are reading the words of an r-slur.

Just get an AWS subscription and use spark at that point, shit
Jump in the discussion.
No email address required.
No offense bro, but this is bad advise. This entire system, with 18 cores, 256 GB or ram, 4TB of NVME and a high end (at the time) GPU was under 5K. If would be even cheaper if you build it yourself. You will never replicate this performance for this price on AWS and spark is bad for any kind of exploratory analysis. Too slow to distribute and collect. Throw on a decent NAS with at least 2.5GB ports and some 10+TB disks and you will to sleep anyone who reaches for AWS for this kind of setup. Cloud can get you to the next level of scale, but most people don't actually need it and reach for it way too early.

I have a server setup with the RAM and processor you're describing, but it's commercial server hardware and cost me $3500. I am absolutely not using it as a desktop computer. My gaming PC cost well under half of that. Are you sure you're not 100% full of shit?

You may be right about cloud compute for price, my compute is all paid for so I've never actually budgeted it out. spark is only slow (even for eda) if you don't know how to use it or youre data is pretty small. Seems like a pain to get that shit together compared to just using a tool meant for dealing with it

Right tool for the right job. Most trading applications arent big data. Its small to medium and very heterogeneous. There are cases where i would still want to run on the cloud because i need access to many more cores or gpus, which is generally at model fitting time.

I imagine the ram sticks are basically all the same size. He just spent a lot of money and slotted them in? Are you fricking r-slurred? Do you think that powerful processors take more space in the case than weaker ones? Are you too stupid to remember how to breathe? Keep yourself safe.

It's "just" that if you're deciding on your setup using only a calculator, but here in reality, there is nothing you can buy to throw in your PC that will support 256 GB.

a gpu is basically its own computer. power handling, central processing, ram, everything done on board
it talks to the 'other' computer thru pcie, does its own thing, and outputs thru displayport or whatevs
we don't complain that gpu ram is soldered on and cards are upsold
gpus should've been a second socketed chip either sharing system ram or with its own bank of upgradable dimms
but cards are more profitable
you can charge thousands for enterprise cards cuz they're the only thing with decent ram (not to mention all the other features merely locked behind software)
